Alternatively, an additional heating return path is formed. The constituent elements of the water heater 2 described above are controlled by a control command from the controller 18. The controller 18 also fetches operation control commands from a hot water supply remote controller 19 as an operation unit for supplying hot water from the water heater 2 to another location, and a wash water injection remote controller 20 which is an operation unit of the laundry water injection mechanism 7, while washing water injection is performed. The configuration is such that a control command is exchanged with the mechanism 7.

The washing water injection mechanism 7 has a third flow path switching valve 21 and a water flow sensor 22, and under the control of the controller 23, a flow path for supplying hot water from the water heater 2 to the bathtub 3,
The third flow path switching valve 21 and the flow path to be supplied to the fully automatic washing machine 6 are selectively switched and formed via the third flow rate sensor 22.

The fully automatic washing machine 7 has a solenoid valve 2 at the water inlet.
Have four. In addition, the fully automatic washing machine 7
In addition to automatically executing operating procedures such as washing, rinsing, and dehydrating, any operating procedure may be used.

Next, the washing water pouring remote controller 20, which is the operating portion of the washing water pouring mechanism 7, will be described. As shown in FIG. 2, the laundry water injection remote controller 20 includes an operation switch 25 and a standby switch 2.
6. It has a washing switch 27, a rinsing switch 28, and an OFF switch 29. The operation switch 25 is for starting and ending the operation of the water heater 2. The standby switch 26 connects the flow path from the water heater 2 to the fully automatic washing machine 6 and the bathtub 3.
The flow path for supplying to the fully automatic washing machine 6 is formed in the ON state so as to follow the start of operation of the fully automatic washing machine 6. By operating the washing switch 27, when the fully automatic washing machine 6 is in the washing mode, the water to be poured into the fully automatic washing machine 6 is selected as hot water, water, remaining hot water, and remaining hot water, and the display unit is displayed. It is a structure displayed on 30. The rinsing switch 28 is used to select hot water or water in the rinsing mode, and is configured to be displayed on the display unit 31. OF
The F switch 29 forcibly turns off the standby switch 26. Further, the laundry water injection remote controller 20 has a wool switch 32, and a washing mode,
In either case of rinsing mode, it corresponds to wool (suitable temperature 25 ° C to 30 ° C) having a relatively low wash compatible temperature of warm water.

The bath apparatus 1 for carrying out the wash water injection method of the bath apparatus having the wash water injection mechanism according to the present invention is constructed as described above, and its operation will be described below. Operation switch 25 of the laundry water injection remote controller 20
Is turned on to start the operation of the water heater 2, and the standby switch 2
When 6 is turned on and the water supply procedure is executed by switching the flow path to be supplied to the fully automatic washing machine 6, (1) hot water is supplied from the water heater 2 to another place while the fully automatic washing machine 6 is in operation, (2)
The operation of the fully automatic washing machine 6 can be executed while hot water is being supplied from the water heater 2 to other locations.

First, (1) a procedure for supplying hot water from the water heater 2 to another place while the fully automatic washing machine 6 is operating will be described with reference to FIGS. 3 and 5. In the washing mode of the fully automatic washing machine 6, the water to be poured into the fully automatic washing machine 6 can be selected by the washing switch 27 as hot water, water, remaining hot water, or remaining hot water. Further, by turning on the wool switch 32, it is possible to inject warm water of 25 ° C to 30 ° C. Here, when the hot water or the wool switch 32 is turned on, hot water of 25 ° C to 30 ° C is selected and water is injected, and the total water supply amount V1 to the water heater 2 detected by the first flow sensor 13 and the second flow sensor. Based on the amount V2 of water supplied to the fully automatic washing machine 6 detected by 15, it is determined whether washing is in use or hot water is being supplied to another place. That is,
If V1 = V2, it is assumed that only washing water is injected.
Continue the washing procedure. On the other hand, if V1> V2, it is assumed that hot water is being supplied, and the hot water supply temperature is set to the predetermined temperature (45 ° C).
Make a comparison judgment with.

Here, the reason for the predetermined temperature (45 ° C.) will be described. Keep the hot water temperature from the water heater 2 high (60
When water is supplied to the washing machine at (° C or higher), the washing machine is made of synthetic resin, so heat deterioration occurs and the washing machine is damaged. Moreover, the object to be washed is also damaged by the high temperature water. Furthermore, the hose connecting the faucet and the washing machine bursts or falls off when hot water of 50 ° C. or higher is continuously passed.
Taking the above points into consideration, the predetermined temperature is set to 45 ° C,
This temperature was set as a threshold.

If the temperature setting is 45 ° C. or lower, the wool switch 32 is turned on to determine whether or not hot water washing wool is set. That is, if hot-water washing wool is set, hot water is supplied to other places as a priority for hot water supply, water injection at a warm water temperature (25 ° C to 30 ° C) suitable for wool is stopped, and a standby state is set. On the other hand, the wool switch 32
If is turned off, the hot water is given priority, and the water is poured into the laundry at the same time with the hot water supplied to another place. If the temperature setting is 45 ° C or higher and the wool switch 32 is turned on, hot water is supplied to other places as a priority for hot water supply, water injection at a warm water temperature (25 ° C to 30 ° C) suitable for wool is stopped, and a standby state is set. . If the wool switch 32 is off, the hot water supply set temperature is set to 45 ° C. or lower to give priority to washing, and simultaneous hot water supply to other locations is executed.

Next, (2) the procedure for operating the fully automatic washing machine 6 while hot water is being supplied from the water heater 2 to another location will be described with reference to FIGS. 4 and 5. When the fully automatic washing machine 6 is operated while hot water is being supplied from the water heater 2 to another location, the temperature setting is 45 ° C. or lower by making a comparative judgment between the hot water temperature required for temperature setting and the predetermined temperature (45 ° C.). Then, the wool switch 32 is turned on to determine whether or not hot-water washing wool is set. If the wool switch 32 is not turned on, the hot water supply is prioritized and the fully automatic washing machine 6 is simultaneously filled with water at the same temperature as the hot water supply temperature. When the wool switch 32 is turned on and the washing water wool is set, the hot water is given priority and hot water is supplied to another place.
Water injection at a warm water temperature (25 ° C to 30 ° C) suitable for wool is stopped and put in a standby state.

On the other hand, when the hot water supply temperature is set to 45 ° C. or higher, first, the wool switch 32 is turned on and off to determine whether hot water washing wool has been set.
That is, if the wool switch 32 is not turned on, the washing priority is given, and the hot water supply temperature to another place is set to 45 ° C. or lower, and the simultaneous hot water supply is performed. When the wool switch 32 is turned on to set hot water washing wool, hot water is given to other places as a priority and hot water temperature (25 ° C to 30 ° C) suitable for the wool is stopped to wait. And

In this way, regardless of whether the laundry is washed first or later, depending on the temperature of the hot water to be poured into the fully automatic washing machine 6 and the hot water supply temperature to other places, the washing water injection can be prioritized. Since the procedure that gives priority to hot water is executed,
Water injection according to the capacity of the water heater 2 is executed, and fluctuations in the amount of hot water and fluctuations in the hot water temperature can be suppressed.

When the washing mode ends after the above water injection procedure is executed, the mode shifts to the rinse mode. In the rinse mode, it is possible to selectively inject water as hot water or water. Further, the wool switch 32 can be turned on to set hot water washing wool, and water can be injected at a warm water temperature (25 ° C to 30 ° C) suitable for wool. At this time, by the rinse switch 28,
When hot water or wool switch 32 is turned on and hot water washing wool is selected, water injection and hot water supply are performed in the same procedure as the water injection procedure in the aforementioned washing mode.

[0019]

As described above, according to the present invention, regardless of whether washing is performed first or later, priority is given to washing water injection depending on the temperature of hot water to be poured and the temperature of hot water supplied to other places. Or, since the procedure that gives priority to hot water supply is executed, always,
Water injection is performed according to the capacity of the water heater, fluctuations in the amount of hot water,
Fluctuations in hot water temperature can be suppressed.
