[0008] V2 is a three-way valve provided in the middle of the return boiler 3 of the return boiler 3 of the additional boiler circulation line 1 in the additional boiler B on the downstream side 3b of the boiler. The switch can be made in any one of a → c, for example, by using an electromagnetic three-way valve or the like so that the switch can be made electrically. Reference numeral 6 denotes a water supply pipe connected to the water supply path a → b of the three-way valve V2 for guiding remaining hot water and the like to the washing machine D. Further, the latter half of the downstream side 3b of the return pipe 3 is connected to the hot water supply path a → c of the three-way valve V2 so as to guide the additional heating circulating flow or hot water from the hot water supply device C to the bathtub A. E denotes a temperature detection sensor for detecting the temperature of the remaining hot water in the bathtub A. In the embodiment, the hot water temperature detection sensor of the additional heating device B is used, but it may be provided separately in the bathtub A and the like. F is a water level detection sensor that detects the level of remaining hot water in the bathtub A to detect the presence or absence of the remaining hot water. It is provided. G is an electronic control unit. The electronic control unit G includes the detection sensors E and F, the on-off valve V1, the three-way valve V2, the circulation pump P, and the gas burner 11 of the water heater 9 of the water heater C.

Is operated. In the figure, reference numeral 13 denotes a hot water supply pipe branched from the hot water supply pipe 5 and piped to a kitchen sink or the like. I have.

The operation of the above configuration will be described below. First, control of water injection to the washing machine D will be described for each mode. (1) Remaining hot water injection mode When pouring the remaining hot water in the bathtub A to the washing machine D when the remaining hot water is cooled to a set temperature or less, when the remaining hot water is to be poured into the washing machine for heating, the following diagram is used. As shown in the flow chart of FIG. 1 and FIG. 3, when the water supply switch of the operation panel 15 is turned on in step 101 and started, it is determined that there is a water supply request in step 102, and the process proceeds to step 103 to supply the remaining hot water 14. The presence or absence is detected by the water level detection sensor F. In this case, since there is remaining hot water 14, the process proceeds to step 104, and it is determined whether or not a hot water request is set by the operation panel 15 (a hot water request is present in this mode). Then, with the on-off valve V1 closed, the three-way valve V2 is switched from the water injection path a to the water injection path b to the b side, and then the circulation pump P is turned on. Thus, as shown in FIG. 1, the remaining hot water in the bathtub A is the upstream side 3a of the recirculation line 1 of the reheating unit B → the circulation pump P → the return line 3 of the circulation line 1. → Heat exchanger 7 of bath kettle 4 → First half of downstream side 3b of return pipe 3 → Three-way valve V2 → Inject water to washing machine D in the route of water injection pipe b. In this case, since the request for hot water has been confirmed in step 104, it is determined in step 105 whether or not the remaining hot water 14 is at or above the set temperature, and the temperature detection sensor E detects that the temperature is at or below the set temperature. Then, a heating required command is output to burn the gas burner 8 of the bath kettle 4 of the reheating unit B, and to supply hot water while heating the remaining hot water passing through the heat exchanger 7.

(2) Remaining Hot Water Injection Mode When the remaining hot water in the bathtub A is injected into the washing machine D without heating without heating, the process proceeds to step 104 in the same manner as in the above-described remaining hot water heating and water injection mode. It is confirmed that there is no demand for hot water, and the three-way valve V2 is switched from the water supply path a to the water supply path b while the on-off valve V1 is closed to the b side, and then the circulation pump P is turned on. In this mode, since there is no demand for hot water, the gas burner 8 is not burned, and the remaining hot water is poured into the machine D for washing as it is.

(3) Hot water supply / pour mode When the hot water is supplied to the washing machine D and the water level detection sensor F detects that there is no remaining hot water in the bathtub A, as shown in the flowcharts of FIGS. Then, the process proceeds to step 106 to determine whether or not there is a request for hot water (in this mode, there is a request for hot water). Then, the on-off valve V1 is opened to connect the reheating unit B and the hot water supply device C, and the three-way valve V2 is switched from the water supply path a to the b side to the b side. Water such as tap water is passed through the pipe 12. Therefore, the tap water or the like is supplied to the water supply pipe 12 of the hot water supply device C → the heat exchanger 10 of the water heater 9 → the hot water supply pipe 5 → the upstream side 3a of the return pipe 3 in the additional heating circulation line 1 of the additional heating apparatus B → The water is supplied to the washing machine D by following the path of the heat exchanger 7 of the bath 4 → the first half of the downstream side 3 b of the return pipe 3 → the three-way valve V 2 → the water supply pipe 6. At this time, the necessity of heating is determined in step 107 based on the request for hot water, and if cold water is supplied, the gas burner 11 of the water heater 9 of the water heater C is burned based on the heating necessary command. The heat exchanger 10 is heated and the hot water at the set temperature is poured into the washing machine D. It should be noted that the water injection does not flow toward the forward pipe 2 at the check valve V3. In this case, the gas burner 8 of the bath kettle 4 of the reheating apparatus B may be burned. In addition to the water injection to the washing machine D, water supply or hot water supply to a kitchen sink or the like can be performed at the same time.

(4) Water Injection Mode In the hot water supply / injection mode described above, when hot water is not required, the operation panel 15 does not set a hot water request, so that it is determined in step 106 that there is no hot water request, and the on-off valve V1 Is opened to make the reheating unit B and the hot water supply device C communicate with each other, the three-way valve V2 is switched from the water supply path a to the b side to the b side, and tap water or the like is supplied to the water supply pipe 12 of the water supply apparatus C while the circulation pump is OFF. Pass water. In this case, the burners 11 and 8 are kept in a combustion stopped state, and tap water or the like supplied to the hot water supply device C is poured into the washing machine D as it is.

Next, the hot water supply and additional heating operations will be described. When new hot water is supplied from the hot water supply device C into the bathtub A, the open / close valve V1 is opened to connect the additional heating device B with the hot water supply device C, the three-way valve V2 is switched from the hot water supply path a to c, and the circulation pump P When the water temperature is turned off and the gas burner 11 of the hot water unit 9 is burned at the same time as tap water is passed through the water supply pipe 12 of the hot water supply device C, the temperature of the set temperature raised by the heat exchanger 10 of the hot water unit 9 is increased. The hot water is supplied to the hot water supply pipe 5 → the upstream side 3a of the return pipe 3 in the additional heating circulation line 1 of the additional heating apparatus B → the heat exchanger 7 of the bath 4 → the first half of the downstream side 3b of the return pipe 3 → The three-way valve V2 is supplied in the order of the second half of the downstream side 3b of the return pipe 3 to the bathtub A. In addition to the hot water supply to the bathtub A, the hot water supply to the kitchen sink can be performed at the same time simply by opening the hot water tap.

When supplying hot water only to a kitchen sink or the like, the gas burner 11 of the water heater 9 burns when hot water is supplied by opening the hot water tap provided at the end of the hot water supply pipe 13 by closing the open / close valve V1.

In order to reheat the water in the bathtub A, the on-off valve V1 is closed and the three-way valve V2 is switched from the hot water supply path a to c. Then, the circulation pump P is turned on and the gas burner 8 of the bathtub 4 is turned on. When the fuel is burned, the hot water in the bathtub A is discharged from the forward pipe 2 → the circulation pump P → the upstream side 3 a of the return pipe 3 → the heat exchanger 7 of the bath 4 → the first half of the downstream side 3 b of the return pipe 3 → three directions The valve V2 → the second half of the downstream side 3b of the return pipe 3 → recirculates along the route of the bathtub A and is heated and heated. Each of the modes (1) to (4) and the hot water supply / post-heating operation is performed based on the set values and commands input from the operation panel 15 and the detection values from the detection sensors E and F. G automatically controls the circulation pump P and each of the valves V1, V2, V4, V5, and the like.

[Effect of the invention]

 As described above, this device allows the remaining hot water to be heated by the additional heating device and then injected into the washing machine with the circulating pump, so that it does not consume extra fuel and has a longer waiting time until water is injected unlike the conventional device. It is unnecessary and convenient. In addition, when hot water is not required, it is economical because the remaining hot water can be poured directly into the washing machine with a circulation pump without heating. In addition, since tap water can be injected as it is or as hot water, rinsing with clean hot water or water can be performed freely, and it is economical because water can be heated according to the need for hot water. . For example, it is possible to selectively use the hot water pouring only when using a detergent such as a bio-detergent whose cleaning effect is remarkably improved with hot water, which is very convenient. In addition, according to the bath apparatus with a washing water injection function according to the second aspect, the user switches between the water injection modes based on the presence / absence of remaining hot water in the bathtub, the temperature of the remaining hot water, and the presence / absence of a hot water request. There is no need to confirm, and it is easy to use.
