The present embodiment is configured as described above.
The cleaning operation will be described based on the flowchart shown in FIG. First, when the cleaning button 31 of the remote control 30 is turned on,
The ON signal is applied to the control unit 28, and the drain signal 13 is opened by the control signal from the control unit 28 to drain the dirty bath water when the bathtub 1 is filled. Then, it is determined in step 102 whether or not the drainage of the hot water is completed.

That is, after transmitting the open signal of the drain valve 13 in step 101, the control unit 28 determines whether or not the T time required until the hot and cold water in the bathtub 1 completely flows has passed is determined using, for example, an internal timer. Do it. Drain valve 13 while T time does not elapse
Is left open, and when the time T has elapsed, it is determined that the water in the bathtub 1 has been completely drained, and the drain valve 13 is closed. Then, in step 104, the detergent on-off valve 16 is opened,
At the same time, it is judged whether or not ₁ h predetermined T has elapsed in step 105. That is, the control unit 28 is a detergent on-off valve
After the open signal was added to 16, a predetermined amount of time to count the time by using an internal timer, while the time T ₁ has not elapsed leave open the detergent-off valve 16, the time T ₁ has elapsed (For example, 20 cc) of detergent is supplied from the detergent tank 23 to the detergent supply pipe 19.
It is determined that the liquid has been supplied to the return pipe 20 and the detergent on-off valve 16 is closed.

Next, at step 107, the water supply on-off valve 27 is opened. Then, washing water such as tap water is supplied to the bathtub together with the detergent through the return pipe 20 and the washing liquid supply pipe 15 through the water supply pipe 26.

The T ₂ hours washing water that is supplied to the tub, (mixture of water and detergent) cleaning liquid required for operating smoothly the pump 17 on the bottom side of the tub is accumulated. If the amount of the cleaning liquid is too small, the air in the bathtub 1 is sucked from the return pipe 20 when the pump 17 is started, which impairs the smooth operation of the pump. In contrast, the water supply on-off valve 27 is
By supplying the washing water after opening for T ₂ hours, an amount of washing liquid that does not hinder the operation of the pump is secured, and the smooth operation of the pump is enabled.

After the T ₂ hours have elapsed, the water supply on-off valve 27 is closed,
In step 110, the pump 17 is started. This pump 1
By the activation of 7, the cleaning liquid accumulated at the bottom of the bathtub 1 is sucked into the pump 17 through the return pipe 20, and the sucked cleaning liquid passes through the pipe 24 from the discharge side of the pump 17 to the heat exchanger 25. Here, the cleaning liquid is heated to a temperature suitable for exerting the chemical cleaning ability, in this embodiment, 50 to 60 ° C., and the heated cleaning liquid of the hot water is supplied from the heat source outlet pipe 18 to the cleaning liquid supply pipe 15. The water enters the bathtub from the washing nozzle 14 to remove dirt from the inner wall surface of the bathtub.

The jetted cleaning liquid flows down to the bottom side of the bathtub 1, and the cleaning liquid flowing down to the bottom side returns to the return pipe 20.
Then, after being sucked by the pump 17 and similarly passing through the heat exchanger 25, it is jetted from the washing nozzle 14 into the bathtub through the washing liquid supply pipe 15. As described above, the temperature control of the cleaning liquid is performed step by step while the circulation injection of the cleaning liquid is repeatedly performed using the circulation pipe.
It is performed from 111 to 114.

That is, based on the temperature detection signal obtained from the temperature sensor 22, the control unit 28 sets the temperature of the cleaning liquid to T ₃ ° C (for example, 60 ° C).
It is determined in step 111 whether the value is less than or equal to. When the temperature of the cleaning liquid is lower than T ₃ ° C, the gas burner of the heat exchanger 25 is burned in step 112 to heat the cleaning liquid. The temperature of the washing liquid in step 113 it is determined whether it is T ₃ ° C. or more, T ₃ at below ° C. was heated continue performing combustion of the burner of the heat exchanger 25, the temperature of the cleaning liquid T ₃ ° C. or higher In step 114, the burner combustion of the heat exchanger 25 is stopped in step 114.

Next, in step 115, the pump 17
There it is judged whether or not the lapse T ₄ hours is started.
When not elapsed T ₄ hours repeats the operation from step 111 114 continues to control the temperature of the washing liquid circulating injection to a temperature of T _3. Time the pump 17 is stopped in step 116 when the elapsed T ₄ hours, open the drain valve 13. Then, in step 117, the water supply on-off valve 27 is opened. Then, the cleaning water supplied from the water supply pipe 26 passes through the heat exchanger 25, passes through the heat source outlet pipe 18, the cleaning liquid supply pipe 15, is jetted from the cleaning nozzle 14 to the inner wall surface of the bathtub, and adheres to the inner wall surface of the bathtub. The cleaning solution and the dirt components removed by the cleaning solution are washed off to the bottom side of the bathtub 1. On the other hand, the washing water supplied from the water supply pipe 26 is also supplied to the bottom side of the bathtub 1 through the return pipe 20, and the washed washing liquid and the dirt component are discharged out of the discharge unit 12. . In step 118, the water supply on-off valve 27 is determined whether or not it has passed a predetermined T ₅ hours opened, after washing off of T ₅ hours is performed in succession,
In step 119, the water supply on-off valve 27 is closed, and the automatic cleaning of the bathtub 1 is completed. After the washing of the bathtub 1 is completed, the drain valve 13 is closed and the bathtub 1 is appropriately filled with water.

Next, the reheating operation will be described with reference to the flowchart of the reheating operation shown in FIG.

First of all, with the bathtub filled with water, the reheating button
When 35 is turned on, the signal is applied to the control unit 28.
The control unit 28 receives this signal and starts the pump 17 in step 201. Then, return pipe 20 to pump 17, pipe line 2
4. Circulation of hot and cold water is performed through a circulation pipe that reaches the washing nozzle 14 via the heat exchanger 25, the heat source outlet pipe 18, and the washing liquid supply pipe 15. At this time, it is determined in step 202 whether the circulation of the hot and cold water is normally performed. That is, the control unit 28 receives the water flow detection signal from the water flow sensor 21, and when an appropriate amount of hot water flow is not detected in the circulation conduit, determines that the water filling to the bathtub 1 is incomplete, and at step 207 the pump Stop 17 and immediately stop the reheating operation. On the other hand, when the flow of the appropriate amount of hot water is detected, it is determined that the water filling is performed normally, and the temperature control of the additional hot water is performed in the next steps 203 to 206.

That is, in step 203, the detected temperature of the hot water temperature detected by the temperature sensor 22 is compared with the reheating setting temperature set by the temperature setting unit 36, and when the detected temperature is equal to or less than the reheating setting temperature T _S ° C. It is determined whether or not there is. When the detected temperature is equal to or higher than the set temperature T _S ° C, it is determined that reheating is unnecessary, and the pump 17 is stopped in step 207 to stop the reheating operation.
Step 20 when the detected temperature is lower than the reheating set temperature
In 4, burner combustion of the heat exchanger 25 is performed to heat the circulating hot and cold water. Then, in step 205, it is determined again whether the hot water temperature has become equal to or higher than the reheating setting temperature T _S ° C. When the detected temperature is lower than the set temperature, the hot water is continuously heated by the heat exchanger 25, and when the detected temperature becomes equal to or higher than the reheating set temperature T _S ° C., the combustion of the burner of the heat exchanger 25 is stopped, Subsequently, at step 207, the pump 17 is stopped to end the reheating operation.

According to the present embodiment, since the cleaning unit 32 is housed and mounted in the wall hole 10 for the supply / exhaust tube of the balance bath, even if the cleaning machine is installed, this narrows the effective use space of the bathroom 9. Therefore, an automatic washing machine can be introduced without trouble even in a small bathroom.

Further, the maintenance of the bathtub washer can be performed from the bathroom without the necessity of assembling a scaffold outside the bathroom 9, which is very convenient. The effect is particularly remarkable in a multi-story apartment house.

Further, since the balance bath is removed from the bathroom 9, the bathtub 1 can be enlarged accordingly, and the bath can be enjoyed in a relaxed mood.

The present invention is not limited to the above embodiment,
Various embodiments may be employed. For example, in the above embodiment, one washing nozzle 14 is provided on the inner wall surface of the bathtub. However, as shown by a broken line in FIG. 2, for example, a plurality of washing nozzles 14 are provided on the inner wall surface of the bathtub, The cleaning liquid supply pipe 15 may be connected to each cleaning nozzle 14 from the heat source outlet pipe 18 by piping.

Further, in the above embodiment, the heat exchanger 25 is configured to perform the heating of the cleaning liquid and the heating of the reheating water, but the heat exchanger 25 only heats the cleaning liquid, and the reheating of the hot water is performed in the bathroom. An electric water heater is installed in the water heater, and reheating is performed using the water heater, or reheating is performed by supplying high-temperature insert water from a water heater provided in a separate room such as a kitchen. You can also. When the heat exchanger 25 is not used as a heat source for reheating as described above, the washing nozzle 14 can be installed at a place other than the bathtub, for example,
As shown in FIG. 5, it may be provided on the lid 2 side of the bathtub 1,
Further, as shown in FIG. 6, the lid 2 is formed in a folded shape, a cleaning nozzle 14 is provided at a central portion of the lid 2, and a cleaning liquid supply pipe 15 is connected to a base end side of the lid 2, and the cleaning liquid supply pipe 15 is connected. Tube 15
A passage 34 for the washing liquid from the nozzle 2 to the washing nozzle 14 may be provided inside the lid 2.

In the above embodiment, the cleaning liquid is heated by the heat exchanger 25. However, the heat exchanger 25 may be omitted, and the cleaning liquid that is not heated may be injected from the cleaning nozzle 14 toward the inner wall surface of the bathtub. . However, when the cleaning liquid is heated by the heating source as in the present embodiment, the cleaning power of the cleaning liquid is enhanced, which is more preferable.

Further, in the embodiment, the return pipe 20 is provided on the bottom side of the bathtub 1 so as to circulate and inject the cleaning liquid. However, the return pipe 20 is omitted, and the detergent supply pipe 19 is moved to the suction side of the pump 17. The cleaning nozzle 14 may be connected to the cleaning nozzle 14 to spray the detergent supplied from the detergent tank 23 directly as a cleaning liquid onto the inner wall surface of the bathtub.

Furthermore, in the above embodiment, the detergent tank 23 is
Although it was taken out of the case 32 and provided in the bathroom, the detergent tank 23 can be accommodated in the washing unit 32 (in the case of the washing unit). However, if the bathtub is cleaned frequently, for example, once a day, it is necessary to replenish the detergent contained in the detergent tank 23 within a relatively short period of time. It is more convenient in use that the detergent tank 23 is put out of the case of the washing unit 32 as in this embodiment and is disposed at an appropriate position in the bathroom where the detergent can be easily replenished.

In the above embodiment, the wall hole 10 for the supply / exhaust tube of the balance bath is used.
If a wall hole for the supply / exhaust tube of the balance bath is already provided on the outer wall of the bathroom in an existing apartment, etc., the wall hole can be used. This eliminates the necessity of the construction work for newly forming the accommodating wall hole of the cleaning unit 32, which is advantageous because the cleaning machine can be very easily introduced. In addition, if the balance bath is removed, a larger bathtub can be set up and the bath can be taken in a relaxed mood.

[Effect of the invention]

In the present invention, the washing unit of the washing machine is accommodated and installed in the wall hole for the supply / exhaust tube of the balance bath in the bathroom. Therefore, the washing machine is installed without narrowing the effective use space of the bathroom. Therefore, it is possible to easily introduce a washing machine even in a house with a small bathroom.

In addition, when installing the cleaning unit and performing maintenance after the installation, these operations can be performed from the inside of the bathroom without building a scaffold outside the building. Is big. Also,
Since the wall holes for the supply / exhaust tube of the balance bath are used, the troublesome work of opening a new wall hole for installing the washing machine is unnecessary, and the installation and introduction of the bathtub washing machine can be performed extremely easily. The effect that it can be obtained is obtained. Further, in a configuration in which the detergent tank of the cleaning unit is taken out of the case of the cleaning unit and disposed in the bathroom, an effect is obtained that it is very easy to replenish the detergent to the detergent tank.
In this case, the use space of the bathroom is somewhat narrowed by disposing the detergent tank in the bathroom, but a large part such as a pump of the cleaning unit is housed in the case of the unit and the supply / discharge of the balanced bath kettle of the bathroom is performed. Since the detergent tank is installed in the wall hole for the cylinder, even if the detergent tank is arranged in the bathroom, there is no particular problem in effective use of the bathroom space.

Furthermore, in the configuration in which the heating source for heating the cleaning liquid is provided in the cleaning unit, the heating source is installed in the wall hole of the bathroom, so that compared to the case where the heating source is installed in the bathroom, The bathroom can be used more widely, and the cleaning liquid supplied to the cleaning nozzle can be heated to a temperature at which the chemical cleaning ability can be exhibited, and the heated cleaning liquid can be sprayed from the cleaning nozzle to the inner wall surface of the bathtub. The synergistic effect of the chemical cleaning power and the cleaning power due to the collision of the cleaning liquid with the cleaning liquid makes it possible to cleanly clean the inner wall surface of the bathtub.

Furthermore, the pipeline from the bottom of the bathtub to the cleaning nozzle is used as a circulation pipeline for both the cleaning liquid circulation and the reheating circulation, and
In the case of devising a configuration in which a heating source that serves both heating of the cleaning liquid and reheating of hot and cold water is provided in the circulation pipeline, cleaning liquid heating and reheating can be performed by one heating source. Is simplified, and the cost of the apparatus can be reduced. In addition, since the dual-purpose heating source is installed in the wall hole for the balanced bath in the bathroom as a washing unit having the function of a bath, the space for installing the bath in the bathroom can be omitted. Minutes, a large bathtub can be installed,
You can relax and take a bath in a large bathtub.
In washing the bathtub, the washing liquid sprayed from the washing nozzle to the inner wall surface of the bathtub is collected from the bottom side of the bathtub, guided again to the washing nozzle through the circulation pipe, and repeatedly circulated and sprayed. It is possible to save (use waste of detergent). In addition, the cleaning liquid to be circulated and jetted is heated by a heating source when passing through the circulation pipe, and can be jetted from the cleaning nozzle at an optimum temperature for exhibiting the chemical cleaning ability of the detergent. By the synergistic effect of the above, the effect of being able to cleanly remove dirt on the inner wall surface of the bathtub is also obtained. Furthermore, at the start of bath tub cleaning, a control structure for automatic preparation of a cleaning liquid for storing an amount of cleaning liquid necessary for pump operation is provided on the bottom side of the bath tub, so that the amount of cleaning liquid collected on the bottom of the bath tub during bath tub cleaning. Is sufficient to smoothly operate the pump, that is, a small amount that does not hinder the operation of the pump.Therefore, the impingement force of the cleaning liquid sprayed from the cleaning nozzle is not greatly reduced by the cleaning liquid accumulated in the bathtub. It can strongly act on the bottom surface, thereby exerting an effect that a strong jet impingement force can be exerted not only on the inner wall surface of the bathtub but also on the bottom surface of the bathtub to clean the entire inner wall surface of the bathtub cleanly. .
