Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath device, and in particular, the bath water is kept clean and at an appropriate temperature while the bath water is kept at the bath temperature while being subjected to cleaning treatment such as filtration and sterilization while forcibly circulating the bath water. The present invention relates to a so-called 24-hour bath device that can be kept for 24 hours and take a bath whenever desired.

[0002]

2. Description of the Related Art Recently, a bathtub hot water purifying apparatus, that is, a 24-hour bath, which constantly keeps hot water in a bathtub clean and at an appropriate temperature, enables comfortable bathing for 24 hours, and saves water, has been actively used. It has become.

[0003] An example of such an apparatus for cleaning bath water is shown in FIG. 6, wherein 1 is a bath tub, 2 is hot water, 3 is a suction pipe for pumping hot water 2 in bath tub 1, and 4 is a hot water suction pipe. An apparatus main body in which devices for cleaning the hot water pumped up by the water suction pipe 3 are collectively provided, and 9 is a fountain pipe for ejecting the hot water treated by the apparatus main body 4 into the bathtub 1 again. .

In order to remove dirt from the bath water, the apparatus body 4 is filled with various granular filter media such as activated carbon, activated stone, porous ceramic balls, etc., or a fibrous filter, individually or in combination, and a filtration tank 5. A circulation pump 6 for forcibly circulating hot water, an electric heater 7 for keeping the hot water at an appropriate temperature, and a cleaning device such as an ozonizer 8 as an ozone generator for sterilizing the hot water with ozone are provided. .

Numeral 10 is a prefilter attached to the tip of the hot water pipe 3 for removing large dirt in advance before it is pumped up to the apparatus main body 4, and 11 is hot water after cleaning treatment in the bathtub 1 as a jet flow having a high flow rate. Intake pipe 1 ejected to the
Reference numeral 2 is a jet nozzle connected to the ejector section.

A solenoid valve 13 for opening and closing the pipe line is provided at the tip of the intake pipe 12 connected to the ejector portion of the jet nozzle 11, and an ozonizer 8 is provided on the way, and when the solenoid valve 13 is opened, the jet nozzle 11 is opened. The air is sucked from the intake pipe 12 by the intake force of the air, and this air is mixed in the hot water at the ejector portion 24, and the hot water is jetted from the jet nozzle 11 into the bathtub 1 together with the hot water to form a bubble bath. The generated air is ozoned and jetted into the bath 1 to sterilize the hot water 2 with ozone.

[0007]

However, in the apparatus constructed as described above, since the hot water is heated by the electric heater, the running cost is high first, and the power consumption of this electric heater is about 800 W. Since it is large, it is inconvenient to use other electric equipment due to the wiring capacity because the cleaning device is installed in the bathroom, and the heating speed of the hot water is slow, so when changing the hot water or operating the device. There was a problem that it took a very long time to heat the hot water to the bathing temperature when the hot water temperature dropped significantly because it was stopped for a long time.

For this reason, recently, as shown in FIGS. 2 and 3, a cleaning pipe and a combustion-type reheating pipe are connected in series or in parallel to replace the heating of the bath water with electricity to generate gas or A kettle oil cleaning device for bath water has also been developed, and the drawbacks of conventional electric heating have been solved, but new drawbacks have arisen due to the connection of a combustion-type reheating conduit to the cleaning conduit. .

FIG. 2 shows an example in which an additional heating line and a cleaning line are connected in series, and 14 is a cleaning device in which the same components as those of the conventional example are designated by the same reference numerals. The cleaning device 14 is provided with a cleaning pipe 15 having a structure of a pipe in which the circulation pump 6 and the filtration tank 5 are provided by removing the heater from the conventional cleaning device. An ozonizer 8 is also provided in the middle of the intake pipe 12 connected to the jet nozzle 11 which is the negative pressure portion of the chemical conversion pipe 15.

Reference numeral 16 denotes a combustion-type reheating device which uses kerosene or gas as a fuel. In addition to the reheating pipe line 17 for reheating the hot water 2 in the bathtub 1 to an appropriate temperature, , A tap water pipe 25 connected to the tap water, a going pipe 26, a heat exchanger 27, a return pipe 28, and a hot water pipe 29 connected to the shower, the currant, etc. are connected in series in order to heat the tap water to supply it to the shower etc. A hot water supply pipe 24 is also provided.

In the reheating pipe line 17, a hot water inlet pipe 18 for inhaling the hot water for reheating and a hot water outlet pipe 23 for discharging the reheated hot water are provided via a forward pipe 19 and a return pipe 22. The reheating pump 20 is connected to the heat exchanger 21, and the reheating pump 20 is a pipe provided in the middle of the outflow pipe 19, and the hot water inlet pipe 18 and the hot water outlet pipe 23 are both connected to the hot water pipe 9 of the cleaning pipe 15. The additional heating line 17 is connected to the cleaning line 15 in series.

Therefore, the hot water 2 in the bath 1 is circulated by the circulation pump 6.
Is sucked into the hot water suction pipe 3 from the pre-filter 10 as a hot water inlet, is cleaned by the cleaning pipe 15 and is first jetted to the hot melt pipe 9, and then the hot water pump 18 is operated to add the hot water from the hot water pipe 18. After being sucked into and reheated by the heating pipe line 17, it is again discharged from the hot water discharge pipe 23 to the hot water discharge pipe 9, and the clean and appropriately heated hot water is again discharged from the jet nozzle 11 serving as a hot water discharge port to the bathtub 1.

In this way, the cleaning line 15 and the additional heating line 17 are provided.
, If the filtration tank 5 of the cleaning line 15 is clogged, the amount of hot water circulating in the additional heating line 17 decreases and abnormal heating of the hot water occurs, causing hot water to jet from the jet nozzle 11 to the bathtub 1. There is a risk that the bather will get burned, and since the circulation pump 6 and the additional heating pump 20 are operating at the same time, the hot water will flow backward and the circulation will not be smooth.

In order to eliminate such a drawback, as shown in FIG. 3, the reheating line 17 is connected to the cleaning line 15 by
The hot water pipe 18 is connected to the hot metal pipe 3, and the hot water pipe 23 is the hot water pipe 9
It is also conceivable to connect in parallel with each other.

Even in such a parallel connection, if the circulation pump 6 and the reheating pump 20 are simultaneously operated, the bathtub 1
Since the hot water sucked from the hot water suction pipe 3 is sucked in both the cleaning pipe 15 direction and the additional heating pipe 17 direction, the operation of the circulation pump is stopped when the additional heating is performed to clean the hot water. There is a drawback that the conversion must be stopped.

As described above, if the reheating pipe line 17 is directly connected to the cleaning pipe line 15, cleaning and reheating cannot be performed at the same time even if they are connected in parallel. Therefore, as shown in FIG. 4 or FIG. One possible method is to separate the inlet and outlet of hot water by the cleaning pipe 15 and the reheating pipe 17.

That is, as shown in FIG. 4, the pre-filter 10 and the jet nozzle 11 as the inlet and outlet of the cleaning pipe 15 and the jet nozzle 11 are provided in the bathtub 1 at the same time as in the conventional case, and at the same time the hot water in the reheating pipe 17 is filled. First, it is conceivable to separately provide the inlet / outlet unit 30 in which the mouth and the outlet are integrated.

However, in the case of this example, it is necessary to make three holes in the wall of the bath tub 1, and there is a drawback that the installation work of the apparatus becomes difficult.

As shown in FIG. 5, as in the case of FIG. 4, the bathtub 1 is provided with an inlet / outlet port unit 30 in which the inlet and outlet of the additional heating line 17 are integrated and is cleaned at the same time. Prefilter 10 as hot water inlet and outlet of pipe 15
And a suction nozzle unit 3 that integrates the jet nozzle 11
This is an example of deploying 1.

In the case of this example, it suffices to make two holes in the bath for mounting the apparatus, but the great feature of the cleaning apparatus is that cleaning can be performed effectively and at the same time the cleaning is completed. It becomes impossible to fully enjoy the bubble bath by jetting the hot water into the bathtub as a jet jet.

In the suction-blow unit 31, the positions of the suction port and the spout are the same, so this suction-blow unit 3
If No. 1 is installed in the lower position of the bathtub, the hot water inlet is located below, so that dirt collected on the bottom of the bathtub can be well sucked in and effective cleaning can be performed, but the jet outlet of the jet flow is located at a low position. The flow does not hit the upper body of the bather and he cannot fully enjoy the bubble bath.

Of course, if the suction fountain unit 31 is arranged in the upper position, the jet flow will hit the upper half of the body of the bather well, and the bubble bath will be fully enjoyed, but dirt collected at the bottom of the bathtub will be removed. Since it cannot be inhaled well, cleaning cannot be performed effectively.

The present invention solves the above-mentioned drawbacks of the prior art, and the apparatus can be easily installed by making two holes in the bathtub, and cleaning and reheating can be performed at the same time. An object of the present invention is to provide a bathtub hot water purifying device that can suck hot water that has been cleaned from the lower position of the bathtub and eject the hot water that has been cleaned from the upper position of the bathtub as a jet flow.

Further, the present invention, even in the device which achieves the above-mentioned object, has an automatic water filling function capable of automatically pouring a predetermined amount of hot water into the bathtub from the hot water supply pipe through the reheating pipe according to the water level of the bathtub. Is also intended to be given.

[0025]

[Means for Solving the Problems] That is, the present invention provides a hot water pipe for sucking hot water from a bathtub for cleaning a cleaning device such as a filtration tank and a hot water pipe for jetting hot water after cleaning into the bathtub. A hot water purification pipe for the bath water that is connected to the bathtub and forcedly circulated by a circulation pump is formed, and a hot water pipe that reheats the heat exchanger through the outflow and return pipes draws in hot water from the bathtub and the reheating ends. The hot water is discharged to the bathtub.It is connected to the bathtub to form a hot water reheating conduit for the hot water that is forcedly circulated by the reheating pump, and the water is heated by a heat exchanger in the hot water heating pipe. The hot water supply pipe is connected by a connecting pipe equipped with a pressure sensor that detects the water level in the bathtub to form an automatic water filling pipe in the bathtub that can automatically fill hot water according to the water level. A hot water inlet unit that connects the hot water pipe and the hot water pipe.
The apparatus for cleaning bath water is characterized in that a spout tube and a spout unit to which the spout tube is connected are provided at an upper position, and a check valve for preventing backflow is provided at the spout tube.

[0026]

The present invention is configured as described above, and since the cleaning pipe and the reheating pipe are not directly connected to each other, the cleaning and the reheating can be performed at the same time, and the bathtub is provided with a hot water inlet. Since it is a unit and a spout unit, the device can be installed by making two holes in the bathtub.

In the cleaning pipe, the hot water pipe is connected to the hot water inlet unit below the bathtub, so that the dirt accumulated at the bottom of the bathtub can be sucked in effectively and the cleaning can be effectively performed. Since it is connected to the spout unit above the bathtub, you can enjoy the bubble bath by directly applying the purified hot water to the upper body of the bather as a jet stream.

Further, since the reheating pipe line and the hot water supply pipe line are connected by the connecting pipe provided with the pressure sensor, the hot water supply pipe line is connected to the bathtub through the reheating pipe line while detecting the water level of the bathtub by the pressure sensor. It is possible to form an automatic water filling pipe that automatically fills water.

Furthermore, since a check valve is provided in the hot water outlet pipe of the additional heating pipe, the hot water inlet pipe of the additional heating pipe is connected to the hot water inlet unit below the bathtub, and the hot water outlet pipe is placed at the upper hot water outlet unit. Even if there is a head difference between the hot water inlet and the hot water outlet, the hot water in the reheating pipeline will not escape even if the hot water supply is temporarily stopped due to the 0 point detection during automatic hot water filling. Absent.

As a result, the pressure sensor provided in the connecting pipe sets the water level at the inlet to 0, and the pressure at a predetermined water level can be accurately detected to accurately and automatically fill the bathtub. .

[0031]

EXAMPLES Next, examples of the present invention will be described with reference to the piping diagram of FIG.

In FIG. 1, since the same components as those of the conventional example are designated by the same reference numerals, the description of these components will be omitted, but the reheating device 16 includes the reheating conduit 17
The forward pipe 19 and the return pipe 28 of the hot water supply pipe 24 are the connecting pipe 3
An automatic hot water filling pipe 32 is formed, which is connected by 3 and injects tap water heated in the hot water supply pipe 24 into the bathtub 1 through the reheating pipe line 17 to fill the water.

A switching valve 34 and a pressure sensor 35 are provided in a connecting pipe 33 for forming the automatic water filling pipe 32. The switching valve 34 heats the hot water supply pipe 24 and returns the hot water to the return pipe. It is a valve for switching the pipe line for sending water from 28 to the hot water supply pipe 29 in order to supply hot water to a shower, a curran or the like, or sending it to the connecting pipe 33 in order to fill the bathtub 1 with hot water.

The pressure sensor 35 detects the pressure of the water level filled up to a higher water level with the pressure at the time when the water is filled up to the reference water level H1 which is the position of the hot water inlet of the bathtub 1 as 0 point. This is a sensor that automatically detects that water is filled up to a predetermined water level H2.

A water flow sensor 36 is provided on the outflow pipe 19 of the reheating pipe line 17 in addition to the reheating pump 20, and the water flow sensor 36 is operated along with the operation of the reheating pump 20.
It is detected whether or not hot water 2 has been sucked from the bathtub 1 to 7, and the combustion burner 38 is ignited or extinguished, and whether or not the hot water has been filled up to the reference water level H1 when the bathtub 1 is automatically filled with water. It is a sensor that detects whether or not.

Further, a check valve 37 is provided in the hot water outlet pipe 23 of the additional heating line 17, and the check valve 37 will be described later in detail in detail. At this time, since the hot water was drained from the automatic water filling pipe 32 and the water was filled up to the reference water level H1 which is the position of the water inlet, the pressure sensor 35 could not detect the pressure and the 0 point adjustment could not be performed. Prevent it from getting lost.

A water flow sensor 39 is also provided in the outflow pipe 26 of the hot water supply pipe 24, and the water supply pipe 25 is provided in the hot water supply pipe 24.
It is determined whether or not the water is supplied from the water supply via, and the combustion burner 40 is ignited or extinguished.

The bathtub 1 has a water inlet unit 41 at a lower position.
Is installed, and a spout unit 42 is installed in the upper position. The cleaning unit 15 is installed in the intake unit 41.
The hot water suction pipe 3 and the hot water inlet pipe 18 of the reheating pipe line 17 are individually connected, and the spout metal pipe 8 of the cleaning pipe line 15 is connected to the jet nozzle together with the intake pipe 12 at the spout mouth unit 42, and is also heated. The tap water pipe 23 of the pipe line 17 is separately connected.

Explaining the automatic filling of water in the pipe as described above, in the automatic filling of water, first, the pressure detected by the pressure sensor 35 at the time of filling the bathtub 1 to the position of the inlet, that is, the reference water level H1 is detected. The water level is set to the standard water level H
The amount of increase of 1 or more is detected by the pressure increase amount of the pressure sensor 35, and when the pressure increase amount corresponding to the water level of H2 which is the predetermined water level is reached, the water filling is stopped and the predetermined water level is reached. Can be filled with water automatically.

When automatic filling is performed based on such a principle, in order to detect that the bathtub 1 has been filled up to the reference water level H1 which is the position of the suction port, the water level of the hot water is the position of the suction port. When the additional heating pump 20 is operated at this point, hot water is sucked into the hot water inlet pipe 18 and starts to flow into the additional heating pipe line 17, and this may be detected by the water flow sensor 36.

Therefore, when the automatic filling is started, first, in order to fill the bathtub to the reference water level H1 and adjust the zero point of the pressure sensor 35, the hot water is supplied for a predetermined time and then stopped. It is necessary to operate the additional heating pump 20 each time to determine whether or not the water flow sensor 36 detects the water flow until the water level reaches the reference water level H1 repeatedly until the water flow sensor 36 detects the water flow. .

However, the hot water inlet pipe 18 and the hot water outlet pipe 23 of the reheating pipe line 17 constituting the automatic hot water filling line 32 are connected to a hot water pipe unit 41 and a hot water pipe unit 42, respectively, which have a head difference.

For this reason, assuming that the check valve 37 is not provided in the hot water outlet pipe 23 of the reheating pipe line 17, when hot water is supplied to the bathtub through the automatic water filling pipe line 32 for filling the bathtub. Although the hot water is discharged from the hot water inlet pipe 18 and the hot water outlet pipe 23 to the bathtub and the automatic hot water filling pipe 32 is filled with the hot water, as described above, it is necessary to detect whether or not the reference water level H1 has been reached. Once the hot water supply is stopped, the hot water filled in the automatic hot water filling pipe 32 is discharged from the hot water pipe 18 to the bathtub 1 and escapes.

In such a state, the standard water level H1 is set in the bathtub 1.
This occurs even when the water flow sensor 36 is filled up with water and the water flow sensor 36 detects this. Therefore, if the hot water in the automatic water filling pipe 32 is drained at this time, it is natural that the pressure sensor 35 produces a pressure corresponding to the water level in the bathtub 1. Cannot be detected, and therefore the pressure sensor 35 cannot be adjusted so that the time when the reference water level H1 is filled with water is zero.

If the pressure sensor 35 cannot be adjusted to 0 when the water is filled to the reference water level H1, it cannot be detected that the water has been water-filled to the predetermined water level H2, so that automatic water filling cannot be performed.

However, if the check valve 37 is provided in the hot water outlet pipe 23, the backflow of the hot water outlet pipe 23 can be prevented even if the hot water supply is temporarily stopped during the automatic hot water filling, so that the automatic hot water filling pipe line 32 is filled. The hot water that is being poured will not be discharged from the hot water pipe 18 to the bathtub 1 and will not escape.

Therefore, the pressure sensor 35 can be adjusted by setting the pressure at the time when the water flow sensor 36 detects the water level up to the reference water level H1 to 0 in the bathtub 1, and naturally, up to the predetermined water level H2. The pressure sensor 35
Detected by, and automatic water filling can be done.

Further, in the above-mentioned piping, if the bathtub 1 is provided with two holes for attaching the hot water inlet unit 41 and the hot water outlet unit 42, the apparatus can be attached and the construction can be simplified.

Furthermore, since the hot water suction pipe 3 of the cleaning pipe 15 is connected to the hot water inlet unit 41 located below the bath 1, the dirt accumulated at the bottom is well sucked in and the hot water is effectively used. Since it can be cleaned and the spout tube 9 is connected to the spout gate unit 42 located at the upper position, the purified hot water can be jetted again into the bathtub 1 while hitting the upper half of the bather's body as a jet stream to enjoy the bubble bath.

[0050]

EFFECTS OF THE INVENTION The present invention has the above-described configuration and operation, and even if the filter medium is clogged, there is no fear of abnormal heating and hot water spouting into the bathtub, so that combustion-type reheating can be performed with peace of mind. (EN) Provided is a bath water cleaning device that can be cleaned at the same time as being heated by a device.

Further, in the bath water purifying apparatus of the present invention, since it is not necessary to make too many holes in the bath for sucking and draining the hot water, the installation work is simple, and the dirt accumulated at the bottom is also absorbed by the hot water pipe. You can effectively cleanse the soup by inhaling it well, and you can enjoy the bubble bath as the jet flow of hot water that has been cleaned up as a jet flow.

Further, in the bath water purifying apparatus of the present invention,
In addition to reheating, it is possible to accurately fill the bathtub with water up to a predetermined water level with high accuracy.
