Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower device connected to a hot and cold water mixing faucet installed in, for example, a bathroom, and in particular, it prevents a problem caused by jetting of hot or cold water deviating from the optimum temperature of the shower. It relates to a mechanism for preventing the discharge of high-temperature water and low-temperature water that have been lost.

[0002]

2. Description of the Related Art A shower head connected to a hot and cold water mixing faucet by a hose is supplied with hot water having a flow rate and temperature adjusted on the faucet side. The mechanism for adjusting the temperature of the hot water is basically a two-valve type that adjusts the valve openings on the water side and the hot water side, respectively, and the valve opening on the water side and the hot water side is detected by detecting the temperature of the hot water. Thermostatic mixing valves that automatically adjust the temperature to maintain the set temperature are also widely used.

In these hot and cold water mixing faucets, hot water lower than or higher than the set temperature may be ejected due to fluctuations in the supply pressures on the water side and the hot water side even with a thermostatic mixing valve. In particular, when hot water is jetted out, it is uncomfortable to take a shower, and if the temperature is too high, it is dangerous. Even when low-temperature water lower than the optimum operating temperature is ejected, it is very difficult to use, especially in the cold season.

To such a temperature fluctuation of the hot water from the shower head, it is one effective means to discharge the hot water of an abnormally high temperature to the outside of the flow path before reaching the shower head. Is. An example of such a mechanism is disclosed in Japanese Patent Publication No. 3-9354.

In this system, a valve body held by a spring made of a shape memory alloy is provided in a flow path extending from a hot and cold water mixing faucet to a shower head, and an open discharge pipe is provided outside the flow path. Then, when the temperature of the hot water is within the comfortable temperature range, the valve body holds the flow passage to the discharge pipe side at a position to close the shape, and when the hot water from the hot and cold water mixing faucet exceeds a certain temperature. The valve element is moved by the deformation of the memory alloy spring to close the flow path to the shower head side and at the same time to open the flow path to the discharge pipe side.

[0006]

However, since the hot water of abnormally high temperature spouts out of the discharge pipe as it is,
The hot water remains hot and runs down to the bathroom floor. For this reason, the hot water will reach the feet of the user, and even if there is no hot water gushing out of the shower, it is necessary for the user to move their feet quickly and escape from the hot water. , You will find it difficult to use.

As long as hot water of an abnormally high temperature is supplied from the hot and cold water mixing faucet, this hot water is discarded from the discharge pipe without being used at all. Therefore, all the hot water is wasted until the temperature is readjusted or the use is stopped.

As described above, in the conventional hot water spouting prevention mechanism, spouting of the abnormally hot water from the shower head can be sufficiently prevented and a comfortable shower can be taken, but the abnormally hot water is discharged. There are new obstacles.

Also, when low-temperature water lower than the optimum operating temperature is suddenly ejected while taking a shower, the person using the shower may change the direction of the shower in a hurry to take cold water. It will be avoided. On the other hand, for example, when the shower head is used while being hung on the wall holder, it is impossible to immediately avoid the body, and the shower head is exposed to low temperature water.

As described above, not only the problem on the high temperature side, but also on the low temperature side outside the optimum use temperature, there are similar problems in terms of usability. However, like the one described in the above publication, only the conventional measures have been focused on measures against high-temperature water, and one issue remains how to prevent low-temperature water ejection in shower facilities. ing.

The problem to be solved in the present invention is to eliminate the danger by removing the abnormally high temperature hot water by radiating it at a low temperature and making it possible to utilize the hot water without wasting it. Is to eliminate the damage caused by this.

[0012]

According to the present invention, in a shower device having a water discharge outlet communicating with a water supply / hot water supply source and having a shower function, a flow path from the water supply / hot water supply source to the water discharge outlet is provided. It is characterized in that a blocking / releasing means for discharging the spray to the outside is provided at the same time as closing the flow path toward the water outlet with the temperature as a boundary.

In such a structure, the boundary temperature is set to the first temperature and the second temperature higher than the first temperature, and the first temperature is set to the first temperature.
When the temperature is lower than the above temperature and / or when the second temperature is higher than the second temperature, the shutoff / release means closes the flow path toward the water discharge port, and at the same time, the system can discharge the spray to the outside.

Further, the water / hot water supply source may be a hot and cold water mixing faucet for mixing water and hot water and discharging mixed water.

Further, the shutoff / release means is made of a shape memory element having a valve body for opening and closing the supply flow path toward the water discharge port, and a shape memory element having a shape memory characteristic of being deformed by a temperature change so that the valve body closes the supply flow path. The shift spring and the spray nozzle having the discharge end exposed to the outside and allowing the passage to communicate with each other only while the valve body closes the supply passage can be used.

The shut-off / discharging means can be detachably provided between the joint provided at the mixed water outlet of the hot and cold water mixing tap and the base end of the hose whose tip is connected to the water outlet having the shower function. You may make it provide in the shower head provided with the water outlet which has a shower function.

[0017]

The temperature of the hot water from the hot water supply / hot water supply source is high by providing the shutoff / discharging means for supplying the water to the spouting port side based on the temperature at a certain boundary or discharging it to the outside without going to the spouting port. Water discharge from the water discharge port automatically stops depending on the situation of low or high temperature, and low-temperature water or high-temperature water is not discharged.

When the first temperature on the low temperature side and the second temperature on the high temperature side are set as the boundary temperatures, the cutoff
Since the discharging means can supply only the temperature range from the first temperature to the second temperature to the spout, it is always comfortable if these temperature range widths are set to those suitable for the shower. Temperature shower watering is obtained. Then, since the high temperature water that exceeds the second temperature is sprayed and goes out, it is possible to make the spray water whose temperature has decreased due to the increase in the surface area, and the low temperature water that is lower than the first temperature can also be discharged into the air. It is released by spraying in a form that does not make you feel cold.

When a hot and cold water mixing faucet is used as a hot water supply source, even if the hot water valve is erroneously operated or the water supply and hot water supply pressure fluctuates drastically even if it has an automatic temperature adjustment function No hot or cold hot water spouts from the spout.

Further, in the case of utilizing the shift spring of the shape memory element and the valve body, the deformation of the shift spring according to the temperature of the hot water from the hot water supply source can be effectively utilized, and it can be electrically operated. No complicated mechanism such as opening and closing of the flow path is required.

If the shut-off / release means is detachably attached between the joint of the hot and cold water mixing tap and the hose of the shower, it can be reformed by incorporating it into an existing product.

Further, when the shut-off / release means is incorporated in the shower head, for example, when the above second temperature is exceeded, high temperature water is sprayed and released, and this released amount is accompanied by a temperature drop due to spraying. It can be used as it is as part of shower watering.

[0023]

The present invention includes a structure for preventing ejection of either or both of high temperature and low temperature deviating from the optimum use temperature. First, an embodiment for preventing ejection of hot water will be described.

FIG. 1 is a left side view showing a shower facility for a bathroom.

In the figure, a faucet body 1 of a hot and cold water mixing faucet is fixed to a wall of a bathroom, and a shower head 3 is connected to a tip of a hose 2 connected to the faucet body 1.

FIG. 2 is a perspective view of the faucet body 1, which is provided with a water pipe 1a and a water pipe 1b which are connected to a water pipe and a hot water pipe which are wall-piped, and a water discharge pipe 1c is provided at the lower end thereof. An inverted J-shaped joint 1d is provided on the back for connecting the flow path to the hose 2 side while being connected. The faucet body 1 has a function of a thermostat mixing valve for automatic temperature control capable of maintaining a conventionally-known wax element, a shape memory alloy, or the like as a temperature-sensing portion and presetting valve openings on the water side and the hot water side. have. At the right end of the faucet body 1, a water discharge pipe 1c
Side and the shower head 3 side are provided with a switching handle 1e for switching the flow path and at the same time for adjusting the flow rate, and a temperature adjusting handle 1f is provided at the left end.

When hot water of an abnormally high temperature is supplied from the faucet body 1 between the joint 1c and the hose 2, the hot water is removed outside until the temperature of the hot water returns to a comfortable temperature for shower use. A shutoff / release means for temporarily stopping the supply to the showerhead 3 side.

As shown in the enlarged vertical sectional view of FIG. 3, this shut-off / discharge means is a cylindrical housing 4 which also serves as a connecting member for connecting the joint 1d to the hose 2 and a spray protruding outward from the peripheral surface thereof. It is composed of a nozzle 5.

Inside the housing 4, there is provided a valve body 4a which is coaxially movable and has a plurality of flow passage holes 4b, and these flow passages are provided at the end of the hose 2 side. Hole 4
A packing 4c on which the b portion is seated is provided. Further, the spray nozzle 5 is located at a substantially intermediate position in the axial direction of the housing 4.
An outflow hole 4d communicating with is opened, and a cylindrical fixed seat 4e for connecting the spray nozzle 5 is provided coaxially therewith.

A bias spring 6 utilizing a normal coil spring is interposed between the valve body 4a and the packing 4c, and a shift spring 7 made of a shape memory element is incorporated between the valve spring 4a and the packing 4c and the end face of the joint 1d. These springs 6,
By appropriately setting the respective spring constant relationships of 7 in FIG. 3, when the mixed water is supplied from the faucet body 1, the resistance against the valve body 4b between the minimum flow rate and the maximum flow rate is shown in FIG. As shown, the peripheral surface of the valve body 4b covers the flow path hole 4d so that it can be held at a closed position. As a result, in the steady state, the valve body 4a closes the flow path to the spray nozzle 5 side and opens only the flow path to the hose 2 side to supply the mixed water to the shower head 3.

In order to maintain the position of the valve body 4a as described above, the temperature of the mixed water is the maximum temperature (eg, 3) which is suitable for the shower.
It is possible under the condition of up to about 5 ° C to 45 ° C). Then, the shift spring 7 using the shape memory element is deformed in the extending direction when the maximum temperature is exceeded, and pushes the valve body 4a toward the packing 4c side to seat it on the packing 4c side as shown in FIG. Have. That is, the shift spring 7 has a characteristic that the generated load increases in an atmosphere of a temperature of 45 ° C. or higher.

By providing the shift spring 7 as described above, when the temperature is below the limit temperature for use of the shower, as shown in FIG.
As shown in (3), only the flow path to the hose 2 side is opened by the flow path hole 4b, and the mixed water can be jetted from the shower head 3. Then, when the temperature exceeds the limit temperature, as shown in FIG.
As shown in, the flow path hole 4b is closed by the packing 4c, the jet from the shower head 3 is automatically stopped, and the mixed water flows out from the flow path hole 4b to the spray nozzle 5 side.

FIG. 5 shows the spray nozzle 5 connected to the fixed seat 4e.
Is an enlarged vertical sectional view, and FIG. 6 is a vertical sectional view taken along the line AA of FIG.

The spray nozzle 5 is provided with a head 5a screwed to the fixed seat 4e and a tip 5b fitted in the center thereof. A communication path 5c communicating with the outflow hole 4b is opened in the head 5a in the axial direction, and an annular flow path 5d communicating with the communication path 5 is provided on the back surface of the chip 5b. Further, in the center of the tip 5b, there is a spray hole 5 having a small inner diameter.
While opening e, the spray hole 5e and the annular flow path 5d are connected by three supply paths 5f as shown in FIG.

These supply passages 5f are formed by denting on the back surface side of the portion where the spray holes 5e are opened, are connected to the spray holes 5e, and have a port 5e-having an inner diameter larger than that of the spray holes 5e.
It has a tangential posture with respect to the inner wall of 1.

In such a spray nozzle 5, the outflow hole 4d
The mixed water from is supplied from the supply path 5f along the inner wall of the port 5e-1, and since the flow passage areas of the supply path 5f and the port 5e-1 are minute, the flow of the mixed water is accelerated. Causes a swirling flow in the port 5e-1. Therefore, the mixed water discharged from the spray hole 5e having a diameter smaller than that of the port 5e-1 is ejected as a small mist in a conical range having the spray hole 5e as its apex.

The direction of the spray nozzle 5 is the housing 4
Although it can be changed in various ways depending on how to attach it, it is preferable to set it in the direction facing the wall or the direction in which it is swung to the left and right, so that spraying does not reach the user's legs or the like.

In the above construction, the inside of the housing 4 is lower than the maximum temperature when the shower is used when the shower head 3 is not used, so that the valve body 4a is shown in FIG.
The flow path is open only to the hose 2 side at the steady position shown in.

When the flow path is switched to the shower side by the switching handle 1e, the mixed water is sprayed from the shower head 3 through the housing 4 and the hose 2.
While the shower head 3 is being used, if the temperature of the mixed water is stable and stable in the set temperature range, the shift spring 7 is not deformed and the supply to the hose 2 side is continued. It

Here, when the mixed water from the faucet body 1 changes to a high temperature side and reaches a temperature exceeding the use limit of the shower, this high temperature atmosphere causes the shift spring 7 to separate from its steady state and extend. Deform. Therefore, as described above, as shown in FIG. 4, the valve body 4a is seated on the packing 4c to close the flow path hole 4b, and at the same time, the outflow hole 4d is opened in communication with the spray nozzle 5 side. As a result, the hot water supply to the shower head 3 side is stopped, and the mixed water is sprayed in the form of mist from the spray holes 5e of the spray nozzle 5.

Since the mixed water from the spray holes 5e is in the form of fine mist of droplets, the temperature of the mixed water is higher than that in the case where the mixed water flows while drawing a streamline as it is because the surface area is increased by the mist formation. It suddenly drops. Therefore, even if the temperature of the mixed water to be discharged exceeds the maximum limit temperature when using the shower, when it is actually discharged to the outside, it becomes low temperature water. For this reason, even if the user's foot touches the foot of the user after being discharged, it does not feel the heat, and it is not necessary to move the foot away from the floor or move the body to avoid hot water. .

As the temperature of the mixed water from the faucet body 1 decreases and returns to the steady temperature, the shift spring 11
The shape memory starts to deform in the direction of contraction, and after returning to the steady state, returns to the position of the valve body 4a shown in FIG. Therefore, when the release of the high-temperature mixed water that has been released to the outside is completed, the appropriate-temperature mixed water is supplied again to the shower head 3 side. This allows the user to comfortably use the shower without bathing in hot water.

Further, since the temperature of the spray discharged from the spray nozzle 5 is low, instead of providing the housing 4 on the back side of the faucet body 1, any position in the flow path to the shower head 3 can be used. Even if it is installed in, the user does not take hot water. Therefore, shut off the shower head 3
By incorporating a discharge means, it is possible to use normal watering when the mixed water temperature is in a steady state, and to use water spraying from the nozzle when the temperature becomes abnormally high,
An example thereof is shown in a schematic vertical sectional view of FIG.

In the figure, the interior of the shower head 3 is provided with an annular space between the shower head 3 and the inner peripheral wall of the housing 8.
Are connected to each other in a double pipe shape, and a water sprinkling plate 9 having a large number of water sprinkling holes 9a is attached to the lower end of the housing 8. The water spray plate 9 has a shape in which a water spray hole 9 a is opened only in a portion occupied by the housing 8 and covers the entire lower end of the shower head 3.

As in the previous example, the valve body 8a having the flow passage hole 8b opened therein, the packing 8c for seating the valve body 8a for closing the flow passage toward the sprinkler plate 9 and the peripheral wall are provided inside the housing 8. It is provided with a plurality of opened outflow holes 8d. Also,
A bias spring 10 and a shift spring 11 made of a shape memory element are incorporated above and below the valve body 8a. The holding of the valve body 8a by the springs 10 and 11, the movement of the valve body 8a due to the temperature change, the positional relationship between the valve body 8a and the outflow hole 8d, and the like are exactly the same as in the previous example.

Around the housing 8, a plurality of spray nozzles 12 are annularly arranged by using a water spray plate 9. The same spray nozzles as those shown in FIGS. 5 and 6 can be directly applied to these spray nozzles 12, and those having appropriate dimensions and shapes with respect to the size of the shower head 3 can be adopted.

Even in such a configuration, if the mixed water has a temperature suitable for the shower, the valve body 8a is held at the position shown in the figure, so that the mixed water supplied from the hose 2 flows through the housing 8. It escapes and is sprayed from the spray hole 9a.

When the temperature of the mixed water exceeds the maximum temperature suitable for use, the valve body 8a is deformed by the shift spring 11 as in the example shown in FIG.
Is closed by the packing 8c, and the outflow hole 8d communicating with the spray nozzle 12 side is opened. Therefore, the high temperature mixed water is sprayed from the spray nozzle 12 in the form of mist, and the mist is formed to obtain the spray having the lowered temperature.

As described above, when the temperature of the mixed water becomes abnormally high, the injection from the spray nozzle 12 is automatically switched. Even if the mixed water in the shower head 3 has an abnormally high temperature, the mist after coming out of the spray nozzle 12 has a low temperature and water droplets do not come into contact with the body. There is no. Therefore, even if the temperature of the mixed water frequently changes and exceeds the preferable temperature, the operation of stopping the water discharge by the switching handle 1e of the faucet body 1 is not necessary, and the temperature fluctuation of the mixed water is eliminated. You can continue to take a shower regardless of whether or not you are wasting hot water.

When the temperature of the mixed water falls and returns to the steady state, the shape memory of the shift spring 11 returns to the state of FIG. 7, and normal water spray from the water spray hole 9a is restarted.

In the above example, it is possible to shut off and release hot water of an abnormally high temperature, but when the optimum operating temperature is deviated not only on the high temperature side but also on the low temperature side, this low temperature water is also shut off and discharged. It is also possible, an example of which is shown in FIG.

In the figure, a joint 1d on the back of the faucet body 1
Then, the cutoff / release means shown in FIGS. 3 and 4 is connected for high temperature cutoff. This high-temperature cut-off / release means is
It is exactly the same as the previous example, and each member is designated by a common code. The operation is also exactly the same as the above description.

At the lower end of the housing 4 for shutting off high temperature, a shutoff / discharging means for shutting off low temperature is connected. The shut-off / release means is the same as that of the high temperature side except for the arrangement of the bias spring and the shift spring and the shape memory characteristic of the shift spring. A mechanism is incorporated and a hose 2 is connected to the lower end.

The flow path hole 1 incorporated in the housing 13
The valve body 13a having the opening 3b can be seated by using the packing 13c on the lower end side as a valve seat, and the peripheral wall of the housing 13 is provided with a fixed seat 13e for opening the outflow hole 13d and connecting the spray nozzle 14. Similarly to the previous example, the spray nozzle 14 has a head 14a with a tip 14b incorporated therein, and the tip 14b can be discharged as spray water.

A bias spring 15 using a normal coil spring is interposed between the valve body 13a and the upper end side of the housing 13, and a shift spring 16 made of a shape memory element is provided between the valve body 13a and the end surface of the packing. Incorporate. These springs 15 and 16 are also springs 6 on the high temperature shutoff side.
7 is the same as the relationship of 7, and when the mixed water is supplied from the faucet body 1, the peripheral surface of the valve body 13a has a flow path hole against the resistance received by the valve body 4b between the minimum flow rate and the maximum flow rate. 13d
Is held in the closed position. As a result, in the steady state, the valve body 13a opens only the flow path to the hose 2 side and the mixed water is supplied to the shower head 3.

The position of the valve body 13a can be maintained under the condition that the temperature of the mixed water is up to the optimum temperature (about 35 ° C. to 45 ° C.) which is suitable for the shower, as in the high temperature shut-off side. The shift spring 16 using the shape memory element has a shape memory characteristic of deforming in a contracting direction when the temperature is lower than the lower limit value of the optimum temperature. That is, the shift spring 16 has a characteristic that the load generated in the temperature atmosphere of 35 ° C. or less.

By providing the shift spring 16 as described above, when the temperature of the mixed water becomes 35 ° C. or lower, the spring constant of the shift spring 16 is lowered and the balance with the bias spring 15 is disturbed. By the urging force of the valve body 13a, the valve body 13a is seated on the packing 13c similarly to the movement of the valve body 4a shown in FIG. 4, and the flow passage hole 8b is closed and the outflow hole 8d is opened at the same time. Therefore, the jet from the shower head 3 automatically stops,
The mixed water flows out from the flow path hole 4b to the spray nozzle 16 side.

As described above, by providing the high-temperature side and low-temperature side shut-off / release means, when the mixed water toward the shower head 3 exceeds 45 ° C., it is discharged in the form of mist from the spray nozzle 5 and also mixed. When the water falls below 35 ° C., it is similarly discharged from the spray nozzle 14. Therefore, a person taking a shower not only does not take hot water, but can also use it without worrying about being exposed to cold water.

The low-temperature hot water discharged from the spray nozzle 14 is sprayed in a mist form from the tip 14b. For this reason, even if the temperature is low in the flow path before being sprayed, it is dissipated in the air in the form of a mist, so that even if it touches the body, it is less likely to feel cold. Also, when low temperature water is released after taking a shower at an appropriate temperature, the temperature in the bathroom is also high, so the mist of low temperature water tends to rise in this temperature atmosphere. , It does not affect the actual use.

[0060]

According to the present invention, when hot water above or below the temperature suitable for showering is supplied, it is possible to discharge water in the form of spray to the outside without sprinkling water from the spout, so that the person using the shower is hot. Not only does it not be exposed to hot or cold water, but even when hot water is discharged, it is sprayed and the temperature drops sharply, so even if the discharged water touches your feet, you can safely use it without feeling any heat. it can.

Furthermore, when a hot and cold water mixing faucet is used as a hot water supply source, even if the valve operation is erroneous or the temperature of water supply or hot water changes if it has an automatic temperature control function,
You can always use it safely.

Further, in the case where the shift spring and valve body made of a shape memory alloy are used as the shut-off / release means, a simple structure can be obtained by utilizing the relationship between the shape memory characteristic of the shift spring and the temperature of the hot water. Yes, there are no cost obstacles.

Further, if the shut-off / release means is detachably attached between the joint of the hot and cold water mixing tap and the hose of the shower, it can be easily incorporated into an existing product and can be sufficiently adapted to reform.

If the shut-off / release means is incorporated in the shower head itself, even if the hot water reaches an abnormally high temperature while taking a shower, only the mist whose temperature has been lowered due to spraying is used. There is no need to damage people or interrupt the shower on the way, improving usability. Further, since it is possible to take a shower without wasting hot water, it is preferable in terms of energy saving.
