Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub apparatus, and more particularly, to a bathtub hot water purifying apparatus for purifying hot water in a bathtub to keep the hot water constantly clean. The present invention relates to a hot water suction device attached to the tip of a hot water suction pipe that sucks hot water from a bathtub.

[0002]

2. Description of the Related Art Recently, hot water in a bathtub is sucked up by a circulation pump, dirt is filtered by a filter device, heated by a heater, and further sterilized by ozone so that the hot water is constantly kept clean and can be bathed for 24 hours at any time. A bath water purifier has been developed and widely used.

In the bath water purifying device, since the hot water contains a large amount of large dirt such as hair, the filter material of the filtering device is clogged in a short period of time, or a device such as a circulation pump or a water flow sensor. It is preferable to attach a prefilter for removing a large amount of dirt to the tip of the water-absorbing tube in order to prevent the hairs from being damaged due to hair sticking.

Further, recently, a so-called bubble bath device, which circulates hot water in a bathtub and accelerates the flow velocity of the hot water by using a jet jetting device and jets it again into the bathtub as a jet jet mixed with air, is widely used for household use. Has come.

Therefore, even in the bath water purifying device, a jet spouting device is provided as a spouting device so that the purified hot water is not simply spouted into the bathtub as a natural flow.
In many cases, it is becoming a device that ejects as a jet jet so that you can also enjoy a bubble bath.

An example of such a bath water purifying apparatus is shown in FIG.
As shown in FIG. 1, this device sucks the hot water 2 in the bathtub 1 with the hot water pipe 3 having the prefilter 4 attached at the tip by the operation of the circulation pump 7, and first filters the dirt with the filtering device 5, and subsequently, Heat it with the heater 6 so that it keeps a certain temperature,
The heated hot water is jetted again from the jet jetting device 9 at the tip of the jet pipe 8 into the bath 1.

An intake pipe 10 provided with an electromagnetic valve 11 is attached to the jet injection device 9, and an ozone pipe 12 provided with an electromagnetic valve 14 and an ozonizer 13 is branched from the intake pipe 10.

In the apparatus constructed as described above, the solenoid valve 1
If both 1 and 12 are closed, the jet ejector 9
Although hot water is jetted out in the normal state, when the solenoid valve 11 is opened, it is sucked from the intake pipe 10 and a jet jet in which air is mixed in hot water is jetted to form a bubble bath.

Further, when the solenoid valve 14 is open, the hot water mixed with the air ozonized by the ozonizer 13 is used as the jet jet from the jet jetting device 9 to form the jet jet.
The hot water 2 is sterilized by ozone.

When the ozone-generated air is jetted into the bathtub by the jet jetting device and sterilized, the hot water can be effectively sterilized, and the slime of the bathtub and the growth of mold on the bathroom wall can be prevented. By doing so, the function of the bath water purifying device is further improved.

In order to facilitate the attachment to the bathtub and the piping, the hot water suction device in which the prefilter is installed and the hot water spray device in which the jet ejection device is installed are not directly attached to the bathtub, In many cases, the pipe is attached to the bathtub as an integral suction unit.

An example of a conventional hot-water spray unit is shown in FIG. 12, in which the hot-water jet mechanism in which the jet jetting device 9 is installed is located at the upper side, and the hot-water suction mechanism in which the prefilter 4 is installed is located at the lower side. A hot water pipe 3 and a hot water pipe 8 which are attached to the bathtub 1 as a unit 15 and are connected to a cleaning unit 16 in which a filter device or the like is provided in the hot air jet unit 15.
Is connected to the bathtub 1 while being fixed to the bathtub 1 by a transfer rod 17.

[0013]

However, the conventional suction and injection unit has a drawback that the hot water inlet and the hot water outlet cannot be provided at arbitrary positions in the bathtub.

That is, it is preferable that the hot water inlet is provided below the bathtub as much as possible in order to remove the dirt of the hot water in the bathtub that has settled at the bottom of the bathtub.

On the other hand, it is preferable that the spout is provided above the bathtub as much as possible in order not to weaken the strength of the jet jet due to the resistance due to water pressure or to apply the jet jet to the upper part of the body of the bather. .

[0016] However, in the suction unit in which the hot water suction mechanism and the hot water jet mechanism are integrated as described above, since the position of the hot water suction port and the hot water spout are arranged at predetermined positions, Especially when the bathtub is deep, it is difficult to dispose both the inlet and the outlet in preferable positions.

When the bath is deep, if the suction unit is installed so that the position of the spout is as low as possible, the position of the spout will also be considerably lower, and conversely If you install the suction unit so that the position is on the upper side, the suction port will be on the upper side and the dirt sunk on the bottom of the bathtub will not be able to be sucked in.

Further, in the bath water purifier, the prefilter of the hot water absorber is so dirty that it is immediately clogged, the amount of circulating hot water is reduced, and the cleaning ability deteriorates. It must be removed from the hot water absorber and frequently washed, and the hot water absorber is a very important device that governs the ability of the bath water purifier.

Nevertheless, in the conventional hot water absorbing device, it is not easy to attach / detach the prefilter, and it is troublesome to remove and wash the prefilter, so cleaning is neglected, and the lid comes off to attach the prefilter at the time of removal. If the hot water is contaminated by dirt, when installing it, install it upside down to eliminate the effect of the prefilter at all, or if it is upside down and the water inlet is facing up, smoothing the hot water absorption. It caused various problems such as being unable to do so.

It is an object of the present invention to solve the various drawbacks of the prior art as described above and to provide a hot water suction device most suitable for a bath water purifying device.

[0021]

[Means for Solving the Problems] That is, according to the present invention, a hot water in a bathtub is sucked up by a circulating pump from a hot water pipe equipped with a hot water suction device, and a circulation path is provided with various cleaning devices such as a filtering device. In the apparatus for purifying bathtub hot water in which the hot water that has been subjected to the cleaning treatment is forcibly circulated and is again jetted into the bathtub from the spouting apparatus attached to the end of the spout tube, the hot water suction device is A hot water absorbing device for a bathtub hot water purifying device, characterized in that it is formed as a separate hot water absorbing unit, and is connected to a hot water unit through a hot water absorbing pipe to be integrally attached to a bathtub. However, a unit main body with a hot water pipe connection port, a prefilter case with a large number of water passage holes in which a prefilter is housed in this unit main body and detachably attached, and the unit main body or A hot water absorbing device for the bathtub hot water purifying device, comprising a unit cover having a hot water inlet that is detachably attached to the refiller case, and a unit main body and a prefilter that compose the hot water absorbing unit. The case and unit cover are formed in an asymmetrical outer shape, and at the same time, a reverse insertion preventing rib is provided on a mating surface to form a reverse insertion preventing shape in the vertical and front-rear directions. Further, there is provided a brim for attaching / detaching the case to / from the unit body on the outer periphery of the prefilter case of the hot water absorbing unit, which is the hot water absorbing device of the bath water purifying device, and further, the hot water absorbing unit. The pre-filter case and / or the pre-filter is provided with a detaching portion for easily removing the pre-filter from the pre-filter case. It is 吸湯 apparatus of the bath water cleaning apparatus according to claim.

[0022]

The present invention is configured as described above, and the hot water absorbing device is formed as a hot water absorbing unit separate from the hot water melting unit as the hot water melting device, and the hot water absorbing unit is the hot water melting unit through the hot water absorbing pipe. Since it is connected to and integrated with the unit, it is easy to attach / detach the suction / injection mechanism to / from the bathtub and to install piping.

Further, since the hot water unit and the hot water unit are connected by the hot water pipe, the length of this connection can be freely adjusted, whereby the position of the height of attachment of the hot water inlet and the hot water outlet to the bathtub can be adjusted. Can be optimized for each.

Further, the water-absorbing unit has a collar as a handle on the prefilter case so that it can be easily taken out from the unit body. Moreover, since the prefilter is stored in the case in a condition that it can be taken out easily, the prefilter can be washed. It is easy and always kept in a beautiful state, and the effect of cleaning the hot water is further enhanced.

When the prefilter case is removed from the unit body for cleaning the prefilter, the required prefilter case and the unit cover can be removed together, so that the dirty prefilter is exposed in the bathtub and stains hot water. There is no such thing.

Further, since the respective parts to be fitted are formed in a shape for preventing the reverse insertion not only in the upper and lower sides but also in the front and rear sides, the filtration effect by the prefilter is not lost because the prefilter case is attached in the reverse direction. At the same time, by preventing the reverse insertion in the vertical direction, the unit cover can be installed upside down, and the hot water inlet can be reversed so that the hot water cannot be smoothly absorbed.

[0027]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a perspective view of the integrated suction / injection mechanism. Reference numeral 18 denotes a hot water suction unit to which the hot water suction pipe 3 is connected. The hot water suction unit 18 sucks hot water to the hot water suction pipe 3. A unit main body 19 having a pipe connection port on the upper side, a prefilter case 20 for accommodating a prefilter fitted to the unit main body, and a unit cover having a hot water inlet port which is fitted with the prefilter case 20 and covers the front surface of the case on the lower part. A suction cup 22 for detachably attaching the hot water suction unit 18 to the bathtub is attached to the rear side of the rear surface of the unit body 19.

Reference numeral 23 is a fountain unit. The fountain unit 23 is connected to a fountain pipe 8 and an intake pipe 10, and the air sucked from the intake pipe 10 is mixed with the hot water sent from the fountain pipe 8 to form a jet jet. A jet ejecting device 9 for ejecting the water is attached, and a suction cup 24 for detachably attaching the fountain unit 23 to the bathtub is attached to the rear side of the rear surface.

Further, since the hot water pipe 3 penetrates through the hot water unit 23, the hot water unit 18 and the hot water unit 23 to which the hot water pipe 3 is connected are connected to each other through the hot water pipe 3. The two are integrated and can be attached to the bathtub and piped together.

In addition, since the length of the hot water pipe protruding below the hot water unit 23 can be freely adjusted, the distance between the hot water inlet of the hot water unit 18 and the hot water port of the hot water unit 23 is the depth of the bathtub to be installed. It can be freely adjusted according to your needs.

Next, the detailed construction of the hot water absorbing unit 18 is shown in the exploded perspective view of FIG. 2, the side sectional view of FIG. 3, the front view of FIG.
Will be described with reference to the side view of FIG.

The unit main body 19 is formed as a case having a predetermined depth with an open front surface, a hot water pipe connecting port 20 is provided on the upper surface, and recesses provided in the prefilter case 20 are provided on the inside of the left and right side surfaces. Is provided with a protrusion 26 for fitting the two suction cups 22 to the left and right on the rear side of the rear surface.
Is rotatably attached in a horizontal direction by a split pin 27, and the hot water absorbing unit 18 is also attached freely at the corner of the bathtub.

Further, as is apparent from the front view of FIG. 7 (a) and the rear view of FIG. 7 (b), the outer shape of the unit main body 19 is formed by cutting out the corners at the lower ends of the rectangle and reversing the vertically asymmetric vertical direction. It has a shape that prevents insertion.

As can be seen from the front view of FIG. 8 (a), the front view of FIG. 8 (b) in which the filters are stored, and the rear view of FIG. 8 (c), the pre-filter case 20 has an open front surface.
This is a case of a predetermined depth in which a large number of water passage holes 28 are provided on the rear surface, and the outer shape of the rectangle is cut out at both lower corners to prevent vertical asymmetric reverse insertion.

On the rear surface of the prefilter case 20, there is provided a predetermined gap to support the prefilter in a state where the flow of hot water is good. Therefore, an outer peripheral rib 29 that surrounds the outer periphery slightly inside, and a vertical rib 30 that connects the vertical and horizontal centers, The horizontal rib 31 is erected, and more bosses 32 are erected.

The outer peripheral rib 29 is not only for accommodating the prefilter at a predetermined gap from the rear surface, but also prevents the water from leaking around the prefilter by the rib provided on the back side of the front surface of the unit cover 21, which will be described later. It also plays the role of holding firmly.

On both ends of the upper portion of the rear surface of the prefilter case 20, diagonal ribs 33, which are slightly higher than the ribs and bosses for supporting the above-mentioned prefilter, are erected so that the corners are notched.

The diagonal ribs 33 are provided because the prefilter has a cut corner, and a gap is provided between the corner of the case and a fingertip so that the fingertip can be stored and taken out easily. This is for facilitating the position alignment when storing in.

On both sides of the prefilter case 20, there are provided projections 34 which fit into the recesses formed on both sides of the unit cover 21, and on the outer periphery of the unit main body 19.
A flange 35 is provided as a handle for facilitating removal from the pre-filter case 20.
The reverse insertion preventing ribs 36 are provided at both ends to prevent the reverse insertion of the unit main body 19 in the front-rear direction.

If a reverse insertion preventing rib 36 is provided on the back side of the rear surface of the prefilter case 20, the prefilter case 20 is attached to the unit main body 19 with its front and back reversed, and the unit cover 21 is obstructed by the reverse insertion preventing rib 36. Since it cannot be attached, notice that the prefilter case 20 is attached to the unit body 19 in the front-rear direction.

37 is a prefilter such as a sponge,
This prefilter 37 has both lower corners cut out so as to match the shape of the prefilter case 20, and both upper corners are also between the corners for facilitating removal from the case as described above. A notch 38 for removal is provided in order to make a gap into which a fingertip can enter, and as a result, the top and bottom and the left and right are symmetrically formed, so that it is not necessary to pay attention to the attaching direction when attaching to the filter case.

As a detaching portion for easily taking out the prefilter 37 from the prefilter case 20, a detachment notch 38 is formed in the prefilter 37 in the above embodiment.
Although the removal notch 39 may be provided on the outer periphery of the prefilter case as shown in FIG. 10, of course, the removal notch is provided at a position where both the prefilter 37 and the prefilter case 20 face each other. It may be provided.

As is clear from the front view of FIG. 9A and the rear view of FIG. 9B, the unit cover 21 has an opening at the rear surface, and the shape of this opening is a rectangle like the filter case 20. It is formed as a case of a predetermined depth, which is formed by notching the corners at the lower end of each of the notches, and which prevents asymmetrical up-and-down reverse insertion.

A hot water inlet 40 is provided below the front surface of the unit cover 21, and a pressing rib 41 is provided at a position surrounding a slightly inner side of the outer periphery on the back side so as to face the outer peripheral rib 29 of the prefilter case 20. .

Further, two vertical ribs 42 are provided on the back side of the front surface of the unit cover 21, and these are ribs for preventing the prefilter 37 from being inserted by mistake in order to prevent the prefilter 37 from being stored by mistake.

In assembling the prefilter unit 18 having the above-described structure, the prefilter 37, which has a symmetrical shape in the vertical and horizontal directions, does not require any particular attention to the mounting direction.
It is accommodated in the prefilter case 20 together with 3, and then the unit cover 21 is fitted to the prefilter case 20 accommodating the prefilter 37.

In this case, the prefilter case 20 and the unit cover 21 are formed in such a size that the outer shapes are tightly fitted to each other, and the projections 34 provided on the outer sides of the left and right side surfaces of the prefilter case 20. Not shown in the drawing, but also fits into the recesses formed on the inside of both the left and right side surfaces of the unit cover 21, so that the unit cover 21 does not come off when the pre-filter case 20 is removed from the unit body 19. Is fitted with.

When the unit cover 21 is fitted to the prefilter case 20, the prefilter 37 accommodated in the prefilter case 20 becomes the prefilter case 2.
Outer peripheral rib 29 and unit cover 21 provided on
The surroundings are firmly pressed by the restraining ribs 41 provided on the, so that no water leaks from the surroundings.

Next, the prefilter case 20 in which the prefilter 37 is housed and the unit cover 21 is firmly fitted is fitted to the unit body 19 attached to the bathtub 1 to which the hot water pipe 3 is connected.

The pre-filter case 20 and the unit body 19 are fitted not only by external fitting but also by a unit case in which the projections 26 provided on the outer sides of the left and right side surfaces of the unit body are not shown. It is also fitted with a recess provided at a position facing the inner protrusions 26 on both left and right side surfaces of 20.

Unit body 1 of prefilter case 20
It is necessary to make it easy to remove from the unit 9 and make sure that the unit cover 21 never comes off from the prefilter case 20 at the time of this removal.

Therefore, the external fitting of the prefilter case 20 with the unit body 19 is weaker than the external fitting with the unit cover 21, but nevertheless, the fitting using the projection 26 is used. Therefore, the prefilter case 20 does not come off from the unit body 19 naturally.

In the assembly of the hot water absorbing unit 18 as described above, the unit main body 19, the prefilter case 20 and the unit cover 21 have the outer shapes which are not vertically symmetrical or the reverse insertion preventing ribs are provided as described above. Since it has a shape that can prevent reverse insertion in the vertical direction and the front-back direction, it can be assembled easily in the correct direction.

The flow of hot water when sucking the hot water in the bathtub from the hot water suction unit 18 is as shown by the arrow in FIG.
Hot water is first sucked in through the hot water inlet 40 of the unit cover 21, large dirt is filtered by the prefilter 37 of the prefilter case 20, then enters the unit main body 19 through the water passage hole 29, and passes through the hot water pipe connection port 25. It flows to the hot water pipe 3 to be cleaned by the cleaning unit.

When the hot water cleaning process is continued for a predetermined time, the prefilter 37 is clogged with relatively large dirt such as hair and small stones, the circulating amount of the hot water is reduced, and the cleaning ability is lowered. As described above, the hot water absorbing unit 18 is disassembled, the prefilter 37 is taken out, and is washed regularly.

When disassembling the hot water absorbing unit 18, first,
When the flange 35 of the prefilter case 20 is held and pulled to the front, the prefilter case 20 together with the unit cover 21 can be easily removed from the unit body 19 attached to the bathtub.

When the plate filter case 20 is removed, as described above, the unit cover 21 is firmly fitted to the pre-filter case 20 and therefore does not come off. Therefore, the dirt attached to the pre-filter 37 is not removed. There is no need to worry about the hot water in the bathtub getting dirty.

Next, the prefilter case 20 removed from the unit main body 19 is brought to the washing place, and the brim 35 of the prefilter case 20 and the cut portion 43 below the unit cover 21 are held and pulled to pull the unit cover 21. It comes off easily.

Finally, the notch 38 for removal of the prefilter 37 is put into the gap 44 formed between the upper part of the prefilter case 20 and the finger is peeled off, and the prefilter 37 is taken out of the prefilter case 20.

Since the prefilter 37 is elastic when it is new, it can be easily taken out from the prefilter case 20 by pinching it with fingers, but it is constantly sucked to the rear surface side of the filter case 20 by the suction force of the circulation pump. Moreover, since the elasticity soon loses due to the deterioration, if it is used for a while, it sticks to the prefilter case 20 and becomes difficult to take out.

However, if the prefilter 37 is provided with the notch 38 for removal as a detaching part, a gap 44 for a finger can be formed between the upper part of the prefilter case 20 and the prefilter case 20 of the prefilter 37.
Easy to remove from.

Further, as shown in FIG. 10, even if the prefilter case 20 is provided with a notch 39 for removal as a removal portion, the prefilter 37 can be easily removed from the prefilter case 20.

When the cleaning of the prefilter 37 is completed,
The hot water absorbing unit 18 accommodating the cleaned prefilter 37 is assembled and the hot water absorbing operation is started again.

At the time of this assembly, as described above,
Since each part is assembled in a shape that can completely prevent vertical and front-back inversion, even if an old man or a child assembles, due to incorrect assembly, the water inlet may be turned upside down, It does not happen that the filter case is turned upside down and the function as a water-absorbing unit cannot be exerted, or things that cannot be fitted together are forcibly fitted to damage the parts.

[0066]

The present invention is constructed as described above, and the hot water suction unit is mounted at a free position independently of the hot water discharge unit, which makes it suitable for sucking dirt below in a bathtub of any depth. A hot water inlet is provided in the pipe, and the hot water suction unit and the hot water discharge unit can be easily attached to the bathtub as a single unit for piping.

Further, when the prefilter becomes dirty, it can be easily removed without any fear of polluting the hot water in the bathtub, so that the prefilter can be washed frequently to prevent clogging, and thus the circulating amount of hot water can be improved. It does not reduce the ability of cleaning to stay forever.

Further, even if the prefilter is removed for cleaning, even when the prefilter is reattached, even an old man or a child does not have to worry that the parts will be inserted upside down and in the reverse direction of the front and back to be fitted by mistake.

As a result, the water inlet may be turned upside down,
It does not happen that the pre-filter case is turned upside down and the function as a hot water absorbing unit cannot be exerted, or the parts that cannot be fitted cannot be forcibly fitted and damaged.
