Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for installing a purification facility for a 24-hour bath mechanism in a bathroom.

[0002]

2. Description of the Related Art The so-called "24-hour bath mechanism", which is capable of continuously using hot and cold water in a bathtub for a long time without being replaced and has a function of keeping hot water and hot water so that it can be bathed at all times, is becoming popular recently. The 24-hour bath mechanism heats and heats the hot and cold water in the bathtub continuously or at regular intervals while circulating it, and also passes through a purification facility to decompose, filter, and sterilize organic matter in the hot and cold water. Purification processing is performed.

To provide such a 24-hour bath mechanism in a bathtub, as shown in FIG. 7, together with a pump, a heater, and other heat retaining / heating means for circulating hot water, a purification treatment such as organic matter decomposition, filtration, sterilization, etc. It is necessary to install a purification facility to do this.

[0004]

In order to construct a 24-hour bath mechanism, in addition to a pump and a heat retaining / heating means, a treatment tank for decomposing / filtering organic matter in hot and cold water and a sterilizing device for sterilizing hot and cold water Since it requires a purification facility equipped with the above, the whole becomes bulky. Therefore, when the 24-hour bath mechanism is to be installed in the bathroom, if it is arranged along the wall surface, there arises a problem that the room becomes too small and the appearance becomes poor.

Therefore, it is conceivable to install the 24-hour bath mechanism outside the bathroom, but in this case, the equipment construction becomes complicated and large-scale.

[0006]

SUMMARY OF THE INVENTION The present invention provides a new installation structure for purification equipment for a 24-hour bath mechanism, which is characterized by a counter installed between a bathtub and a bathroom wall surface. It is to arrange the purification equipment in the lower part of. The purification equipment is installed under the counter installed between the bathtub and the wall surface of the bathroom, and the purification equipment is installed so as to be higher than the floor of the washroom.

The bathtub may be provided with a hot water supply mechanism for automatically supplying hot water adjusted to a preset temperature or a jet bath mechanism for circulating hot water to mix air and blow it out.
When the jet bath mechanism is attached, the pump for the jet bath mechanism and the pump for circulating the purification equipment are shared, and the pump is almost the same height as the upper edge surface of the bathtub formed on the outer surface of the washbasin side of the bathtub. It is possible to adopt a configuration in which the transfer table is provided in the interior space having a certain height.

[0008] It is also conceivable to form a transfer table having an almost same height as the upper edge surface of the bathtub on the outer surface of the bathtub side, and disposing the purification equipment in the internal space thereof.

In this case, when the jet bath mechanism is additionally provided, the pump may be provided below the counter installed between the bathtub and the bathroom wall surface.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION When a bath system is attached to a bathtub for 24 hours, the place of installation of the purification facility having the largest volume among the components is a matter of concern. Generally, the pipes for the bathtub and the bath kiln and the pipes for hot water supply / water supply are stored under the counter installed between the bathtub and the wall surface of the bathroom. In the present invention, the purification equipment is arranged in the lower space of the counter, and the height position thereof is set higher than the floor surface of the washing room. Specifically, the purification equipment may be attached using a bracket that fixes the counter. With such a configuration, the purifying facility is not exposed, and the problems of impairing the appearance of the bathroom and narrowing the bathroom space are solved. Further, since the height position of the purification equipment containing the electric equipment is set to be higher than the floor surface of the washing place, there is no possibility of contact with drainage, and it is possible to prevent an electric shock accident or an electric leakage accident.

When a hot water supply mechanism having a function of automatically supplying hot water adjusted to a set temperature to a set water level when the water level in the bathtub falls below a certain value is attached to the bathtub The hot and cold water mixing tap can be omitted. As a result, the pipes connected to the hot and cold water mixing taps are eliminated from the space under the counter, so that the usable space volume is expanded and a large-scale purification facility can be installed. Therefore, it is possible to install a 24-hour bath mechanism having a higher capacity than the conventional one in the bathroom.

Examples of the hot water supply mechanism include hot water mixing means for mixing hot water and water to obtain hot water of a preset temperature, and a hot water of an appropriate temperature by controlling the heating amount of the water from the water supply source. The water stored in the tank is heated and kept warm so that hot water at a set temperature can be supplied.

When a transfer table having the same height as the upper edge surface of the bathtub is formed on the outer surface of the bathtub in the washing area, it is conceivable to use the internal space of the transfer table as the installation space for the purification equipment. The transfer platform allows elderly people and people with disabilities who struggle to cross the upper edge of the bathtub to sit on the upper surface and move the body so that the bathtub and the washroom can be separated without crossing the upper edge of the side wall of the bathtub. The purpose is to allow people to enter and leave the room. In this way, it is possible to adopt an embodiment in which the storage part of the purification facility is a transfer table which is extremely useful for bathers, although the bathroom volume is slightly reduced.

When a jet bath mechanism is additionally provided in the bathtub, the location of the circulation pump is a problem. Therefore, by providing the transfer table on the outer surface of the bathtub, both the lower part of the counter and the inside of the transfer table can be used as a storage space, and one pump is shared by the 24-hour bath mechanism and the jet bath mechanism. With this configuration, it is possible to provide an embodiment in which a pump in which the purification facility is commonly used for the other space is provided in one of the spaces below the counter and inside the transfer table.

【Example】

[First Embodiment] FIG. 1 shows an embodiment in which a hot water supply mechanism 10 is attached to a bathtub 1 together with a 24-hour bath mechanism 30. The hot water supply mechanism 10 has a hot water supply function that automatically supplies hot water adjusted to a set temperature to a set water level to the bathtub 1, a supply function that automatically supplies hot water to the set water level when the water level falls below a certain value, and a bathtub. When the temperature of the hot water inside becomes lower than a certain temperature, the hot water is circulated to heat the hot water to a set temperature, and the hot water has a reheating function.

By attaching the hot water supply mechanism 10 having such a function, the hot and cold water mixing tap, which is conventionally installed in the counter C installed between the bathtub 1 and the bathroom wall W, becomes unnecessary. Therefore, since a large storage space is secured under the counter C, it is possible to easily store the bath mechanism 30 in this space for 24 hours.

The 24-hour bath mechanism 30 has a pump and a purification facility inside, and the inflow part 30a and the intake port 4 of the bathtub 1 are connected by an intake pipe 41, and the outflow part 30b and the bathtub 1 are connected. The discharge port 2 is a return pipe 4 connected in the middle of the hot water pipe 5.
2 has been contacted. That is, the hot water discharge port 2 for additional heating and the purified hot water return port are used in common.

In this embodiment, the 24-hour bath mechanism 30 is used.
Is a bracket K that fixes the counter C to the wall surface W
We adopted a structure that uses the above to support above the floor of the washroom. This mounting structure has an advantage of preventing the 24-hour bath mechanism 30 including the electric components from coming into contact with water.

FIG. 2 shows an outline of the piping condition and wiring condition of this embodiment. The hot water supply mechanism 10 has a hot water supply path 14 for supplying hot water adjusted to a set temperature to the bathtub 1, and a hot water supply path 26 for circulating hot water in the bathtub 1 by a pump 25 for additional heating. Hot water supply path of hot water supply mechanism 10 and bathtub 1
Of the hot water supply mechanism 10 and the one-mouth circulation port 3 of the bathtub 1 are connected to each other by a suction pipe 8 and a discharge pipe 9 which form a circulation pipe line.

The one-port circulation port 3 for connecting the suction pipe 8 and the discharge pipe 9 communicating with the additional heating passage of the hot water supply mechanism 10 to the bath 1 is a member as shown in FIG. 3, for example. In this, the suction part 3A communicating with the suction pipe 8 and the discharge part 3B communicating with the discharge pipe 9 are provided side by side in one member. By using the one-mouth circulation port 3, there is an advantage that only one opening is provided in the bathtub 1 for connecting the suction pipe 8 and the discharge pipe 9. Of course, although not shown in the drawing, it is also possible to provide two independent openings for suction and discharge in the bath 1.

In the hot water supply passage 14, a hot water supply pipe 7 having a water supply pipe 6 communicating with a water supply source, a heat exchange section 21 and a burner 23.
A hot / water mixer 12, a temperature sensor 13, an open / close valve 15, a vacuum breaker 16 and the like connected to and are provided.
Reference numeral 11 denotes a valve body driving motor of the hot water mixer 12.

On the other hand, in the reheating path 26, the heat exchange section 22,
A reheating function section 20 including a burner 24 and a pump 25 is provided.

The operation of each device in the hot water supply mechanism 10 is performed by the water level detection sensor 18 provided near the bathtub 1 in the suction pipe 8.
Also, it is controlled by the controller 17 based on the information from the hot water temperature detection sensor 19.

As the hot and cold water mixer 12, a hot and cold water mixing tap whose mixing valve body is driven by a motor 11 is used. The controller 17 controls the motor 11 of the hot and cold water mixer 12 based on the water temperature information obtained by the temperature sensor 18,
The mixing ratio of hot and cold water is adjusted so that the water temperature becomes the set temperature. An electromagnetic valve is generally used as the opening / closing valve 15, and an electrically operated valve can also be used.

The water level detection sensor 18 is a pressure sensor for detecting the water pressure of the hot water stored in the bathtub 1, and the position of the water level detection sensor 18 is not only in the middle of the suction pipe 8 shown in the drawing but also inside the bathtub of the mouthpiece circulation port 3. The surface, the surface of the bite circulation port 3 outside the bath,
It is desirable that it is near the bathtub or in the vicinity of the bathtub, and is as low as possible, such as the connection between the bite circulation port 3 and the suction pipe 8 and the inner surface of the bathtub.

The hot water supply mechanism 10 configured as described above operates as follows. When supplying hot water to the bathtub 1, the opening / closing valve 15 is opened through the controller 17. Then, the water from the water supply source and the hot water from which the burner 23 has been heated are supplied to the hot and cold water mixer 12, where they are mixed at an appropriate ratio to become hot water and sent to the hot water supply passage 14. The hot water temperature is constantly measured by the temperature sensor 13, and the controller 17 controls the motor 11 of the hot water mixer 12 based on the water temperature information to move the mixing valve body and adjust the mixing ratio of the hot water so that the hot water reaches the set temperature. To do. The hot water is discharged into the bathtub 1 from the discharge port 2 through the hot water pipe 5 via the vacuum breaker 16 of the hot water supply path 14. When the water level in the bathtub 1 reaches the set value, the water level detection sensor 18 of the suction pipe 8 detects this,
The controller 17 closes the open / close valve 15 to stop hot water supply.

When the amount of hot water in the bathtub 1 drops below a certain level due to the user's bathing or the like, the water level detection sensor 18 detects this and the controller 17 automatically opens the open / close valve 15 to supply hot water to the bathtub 1. Lead inward. Hereinafter, the steps until the water level in the bathtub 1 returns to the set water level are the same as above.

When the temperature of the hot water in the bathtub 1 decreases, the hot water temperature sensor 19 provided in the suction pipe 8 detects it and activates the reheating function. That is, the pump 25 of the reheating function part 20 is started to suck hot and cold water in the bathtub 1 from the suction pipe 8, and is heated by the burner 24 while flowing through the reheating path 26, and then the heated water is discharged from the discharge pipe 9. It is blown out into the bathtub 1 from the bite circulation port 3 via.

The 24-hour bath mechanism 30 continuously or at regular intervals sucks hot water from the intake port 4 through the intake pipe 41, performs an appropriate purification process on the hot water, and then returns it from the discharge port 2 through the return pipe 42. It is returned to the bathtub 1.

In the purification passage 31 extending from the inflow portion 30a to the outflow portion 30b of the 24-hour bath mechanism 30, a pump 32 and a purification facility including a treatment tank 33, a water flow switch 34, and a sterilizer 35 are provided. . A three-way valve 38 is provided on the downstream side of the purification path 31, and a drain pipe 40 is connected to this. The three-way valve 38 is an electric type that is switch-controlled by the driving force of the motor 39. Each of the above devices is controlled by the controller 36.

The treatment tank 33 is mainly for adsorbing and decomposing organic substances in hot and cold water, and contains a filter medium having microorganisms attached thereto. Further, a stirring motor 37, which is provided when periodically removing the processed material accumulated on the surface of the filter medium, is attached.

The water flow switch 34 is for detecting the flow state of the hot water in the purification passage 31. If dust is accumulated in the filter and the hot water intake is blocked, or if the water level in the bathtub is insufficient or water runs out, the flow velocity in the purification path 31 is attenuated or the flow disappears.
The water flow switch 34 detects this and stops the operation of the purification equipment 30.

As the sterilizing device 35, it is preferable to use a sterilizing device such as a sterilizing lamp that can perform sterilizing treatment without contact with hot and cold water, and avoid a device that directly treats hot and drinking water such as addition of a disinfectant.

The drain pipe 40 connected to the three-way valve 38 provided between the sterilization device 35 and the outflow portion 30b in the purification path 31 is discharged from the treatment tank 33 after the cleaning of the treatment tank 33 is performed regularly. It is for discharging the cleaning wastewater to the outside. The cleaning of the filter medium is performed by stirring the inside with a motor 37 attached to the treatment tank 33 to remove the deposits on the surface of the filter medium, and discharging the cleaning wastewater to the outside from a drain pipe 40 connected to a three-way valve 38. It is something to do. The filter medium cleaning process can be automated.

The controller 36 is connected to the pump 32, the filter material stirring motor 37 of the processing tank 33, the sterilizer 35, the drive motor 39 of the three-way valve 38, and the like by wiring to control them.

By combining the 24-hour bath mechanism 30 and the hot water supply mechanism 10, the following advantages can be obtained. When the cleaning of the filter medium in the treatment tank 33 is automated, it is common to wash the filter medium using the hot water in the bathtub 1 and then discharge the cleaning drainage to the outside. Will reduce the water level. Therefore, if left for a long period of time, as a result of periodical automatic cleaning of the filter medium, the hot and cold water in the bathtub 1 may be washed out. When hot and cold water is given from the bathtub 1, the inside of the treatment tank 33 is dried and the microorganisms adhering to the filter medium are killed. Therefore, even if hot and cold water is supplied to the bathtub 1 again, the purification treatment can be immediately executed. It is difficult, and it takes a certain period of time to stabilize the microorganisms. However, since the hot water supply mechanism 10 has an automatic hot water supply function, even if the filter medium cleaning of the treatment tank 33 is automated, hot water is automatically replenished as the water level decreases, so that the above problems do not occur. Therefore,
The function of the 24-hour bath mechanism can be favorably maintained for a long period of time.

In the general 24-hour bath mechanism, it is necessary to provide a heater for keeping heat in the purification passage 31 or the return pipe 42 in order to keep the temperature of the hot water constant so that the bath can be always bathed. In the example, since the hot water supply mechanism 10 has the additional heating function, the heater can be omitted, and the rated capacity of the circuit can be reduced.

[Second Embodiment] In FIG. 4, a transfer table 1a having substantially the same height as the upper edge surface of the bathtub 1 is formed on the outer surface of the bathtub 1 on the side of the washing basin.
It shows an embodiment used as a storage portion of the 4-hour bath mechanism 30.

Since the transfer table 1a needs to have a size such that a bather can sit on the upper surface thereof, the internal space 1b
The volume of will also increase. Therefore, in this embodiment, it is possible to store even a fairly large 24-hour bath mechanism 30.

The intake pipe 41 and the return pipe 42 that connect the 24-hour bath mechanism 30 to the intake port 4 and the discharge port 2 of the bathtub 1 are the flange portion 1c normally formed at the upper edge of the bathtub 1.
Can be disposed on the back side of the.

In this embodiment, since the hot water supply mechanism 10 having an automatic hot water supply function is additionally provided, the hot water mixing plug is omitted in the counter C installed between the bathtub 1 and the bathroom wall W, but When the table 1a is provided and the bath mechanism 30 is provided in the internal space 1b for 24 hours, it is possible to install the hot and cold water mixing stopper on the counter C as in the conventional case.

[Third Embodiment] With a 24-hour bath mechanism,
There is a case where a jet bath mechanism that circulates hot and cold water in a bathtub and mixes air and ejects the air is installed. FIG. 5 shows an embodiment in such a case, in which a hot water supply mechanism 10 is additionally provided, and a pump 50 and piping for circulating hot and cold water are shared by the 24-hour bath mechanism and the jet bath mechanism, and the bathtub 1 The bath mechanism 30 is disposed in the lower space of the counter C that is installed between the bathroom and the wall surface W of the bathroom for 24 hours, and the pump 5 is supplied to the lower space 1b of the transfer table 1a formed on the outer surface of the bathtub 1 on the washing area side.
A configuration in which 0s are arranged is adopted.

Since the lower space of the counter C and the inner space 1b of the transfer table 1a are used as a storage space for the bath mechanism 30 and the pump 50 for 24 hours in this way, the use space of the bathroom or bathtub is narrowed and the appearance is impaired. It is possible to install large equipment with high capacity in the bathroom without any trouble.

In this embodiment, hot water taken by the pump 50 from the intake port 4 of the bathtub 1 through the intake pipe 41 is guided to the bath mechanism 30 for 24 hours and allowed to pass therethrough, and then returned through the return pipe 42 to the discharge port 2a, The air is blown into the bathtub 1 from 2b, and when the jet bath mechanism is in operation, the air taken in from the air switch 53 that also functions as an air intake and a start switch provided in a proper position of the bathtub 1 is discharged from the discharge ports 2a and 2b. It is supposed to be mixed in hot water near the. Further, the intake pipe 41 and the return pipe 42 are arranged on the back surface side of the flange portion 1c formed at the upper edge of the bathtub 1.

FIG. 6 shows an outline of the piping condition and wiring condition of this embodiment. In the drawings, the same numbers as those used in FIG. 2 indicate common components. The present embodiment is different from the first embodiment in that the purification equipment of the 24-hour bath mechanism 30 and the pump 50 are separated from each other.
The flow path switching valve 51 between the cleaning path 31 and the purification path 31, and the flow path switching valve 51 has a piping configuration capable of bypassing the outflow portion 30a and the outflow portion 30b of the purification path 31, and the air switch 53. An air intake solenoid valve 54 for mixing the air taken in through the hot water is provided near the outlet of the return pipe 42, and a controller 55 for the jet bath mechanism that controls the operation of the pump 50 and the air intake solenoid valve 54. And the controller 36 for the 24-hour bath mechanism 30 are communicatively connected.

In the case of using the jet bath mechanism, the flow of the hot water flowing directly from the inflow portion 30a to the outflow portion 30b does not pass through the purification equipment in the bath mechanism 30 for 24 hours by the switching operation of the flow passage switching valve 51. Forming a path. Pump 50
The hot and cold water sucked from the intake port 4 by the flow path switching valve 5
1 is immediately sent out to the return pipe 42 through which air is mixed and blown out into the bathtub 1 from the discharge ports 2a and 2b.

When using the 24-hour bath mechanism 30,
By the switching operation of the flow path switching valve 51, the hot and cold water sucked by the pump 50 passes from the inflow portion 30a through the purification equipment including the treatment tank 33, the sterilization device 35, and the like, and then the outflow portion 30b.
A flow path is formed through the return pipe 42 from the discharge ports 2a and 2b. The pump 50 is preferably set to operate at a high output when using the jet bath mechanism and to operate at a low output when using the 24-hour bath mechanism.

By using one pump 50 for both the jet bath mechanism and the 24-hour bath mechanism as in this embodiment,
It is possible to reduce the rated capacity of the entire circuit, and it is necessary for safety to dispose an insulating transformer when bringing a pump into the bathroom, but this can be done with one unit. Further, by sharing the hot water discharge ports 2a and 2b and the intake port 4, the number of openings formed in the bathtub can be reduced, and the number of filters can be reduced, thereby providing many advantages.

Other Embodiments The embodiments of the present invention can be applied in various ways other than the above. For example, the heat source in the hot water supply mechanism may be gas, petroleum, or electricity, and the heating system may be either an instantaneous boiling system or a hot water storage system.

Further, although the hot water supply mechanism of each of the embodiments has a heating function, the hot water supply mechanism is heated by providing a warming heating means such as a heater in the purification passage or the return pipe of the 24-hour bath mechanism. It is also possible to omit the functional part.

Further, in the third embodiment, the cleaning equipment for the 24-hour bath mechanism is installed in the lower space of the counter, and the pump is installed in the inner space of the transfer table. On the contrary, the pump is installed in the lower space of the counter. It is also possible to adopt a configuration in which the cleaning equipment of the 24-hour bath mechanism is installed in the internal space of the transfer table.

Others The present invention does not prevent various modifications according to the embodiments.

[0053]

According to the present invention, by utilizing the lower part of the counter installed between the bathtub and the wall surface of the bathroom as a storage space for the purification equipment, the volume of the bathtub and the space used in the bathroom can be narrowed, or It is possible to dispose the bath mechanism in the bathroom for 24 hours without spoiling the appearance.

The same effect can be obtained when the transfer table is formed in the bathtub and the bath mechanism is provided in the internal space for 24 hours.

Further, when the 24-hour bath mechanism and the jet bath mechanism are provided together, the circulation pumps of both are shared, and the lower space of the counter and the internal space of the transfer table are utilized, whereby the 24-hour bath mechanism is used.
