I have.

The operation of the above configuration will be described below. First, the 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 and warming machine, the following diagram is used. As shown in the flowchart 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 in step 102 that there is a water supply request, and in step 103
Then, the presence or absence of the remaining hot water 14 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 request for hot water is set by the operation panel 15 (in this mode, there is a request for hot water). Then, with the on-off valve V1 closed, the three-way valve V2 is switched from the water supply path a to the water supply path b to the b side, and then the circulation pump P
Turn ON. Thus, as shown in FIG. 1, the remaining hot water in the bathtub A is forward pipe 2 of the circulation pipe 1 of the reheating unit 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. A command is output to burn the gas burner 8 of the bath 4 of the reheating unit B 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 poured into the washing machine D without heating without heating, the process proceeds to step 104 in the same manner as in the above-mentioned remaining hot water heating and water injection mode. It is confirmed that there is no request for hot water. After the on-off valve V1 is closed, the three-way valve V2 is switched from the water injection path a to the water supply path b to the b side, and then the circulation pump P is turned on. In this mode, since there is no request for hot water, the gas burner 8 is not burned, and the remaining hot water is poured into the machine D for washing.

(3) Hot water supply / water injection mode When the hot water is injected into the washing machine D, when 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. 2 and 3, the process proceeds to step 106 to determine whether or not there is a hot water request (in this mode, there is a hot water request). Then, the on-off valve V1 is opened to connect the additional heating device B and the hot water supply device C, and the three-way valve V2
Is switched to the injection path a → b to the b side, and the circulation pump is
Tap water or the like is passed through the water supply pipe 12 of the hot water supply device C with the FF. Accordingly, the tap water or the like is supplied from the water supply pipe 12 of the water heater C → the heat exchanger 10 of the water heater 9 → the hot water pipe 5 → the upstream side 3a of the return pipe 3 in the additional heating circulation pipe 1 of the additional heating apparatus B → the bath. Heat exchanger 7 of shuttle 4 → First half of downstream side 3b of return pipe 3 → Three-way valve V2 →
The water is injected into the washing machine D following the path of the water injection 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 being supplied, the gas burner 11 of the water heater 9 of the water heater C based on the heating necessary command.
Is burned, the heat exchanger 10 is heated, and hot water at a set temperature is poured into the washing machine D. In addition, water injection is performed by the check valve V3.
It does not flow to the side. Also, in this case, the reheating unit B
The gas burner 8 of the bath kettle 4 may be burned. Also,
Water supply or hot water supply to a kitchen sink or the like can be performed simultaneously with water injection into the washing machine D.

(4) Water injection mode If hot water is not required in the hot water injection mode described above, no hot water request is set on the operation panel 15 so that it is determined in step 106 that there is no hot water request, and the on-off valve V1 To make the additional heating device B and the hot water supply device C communicate with each other,
The three-way valve V2 is switched from the water injection path a → b to the b side, and tap water or the like is passed through the water supply pipe 12 of the water heater C while the circulation pump is OFF. In this case, the burner 11 and the burner 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, and the three-way valve V2 is switched from the hot water supply path a to c,

When the fuel 1 is burned, the hot water of the set temperature heated and raised in the heat exchanger 10 of the water heater 9 is supplied to the hot water supply pipe 5 → the upstream side of the return pipe 3 in the additional heating circulation line 1 of the additional heating apparatus B. 3a → bath pot 4
Heat exchanger 7 → front half of downstream side 3 b of return pipe 3 → three-way valve V
2 → the second half of the downstream side 3b of the return pipe 3 → supply in the same route as the bath A. In addition to the hot water supply to the bathtub A, the hot water supply to the kitchen sink or the like can be performed simultaneously by simply opening the hot water tap.

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

In order to reheat the water in the bathtub A, the on-off valve V1 is closed, the three-way valve V2 is switched from the hot water supply path a to c, and then the circulation pump P is turned on and at the same time the gas burner 8 of the bathtub 4 is burned. Then, the hot and cold water in the bathtub A is supplied to the outgoing pipe 2 → the circulation pump P → the upstream side 3a of the return pipe 3 → 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 →
The second half of the downstream side 3b of the return pipe 3 is refluxed in the same route as the bath A, and is heated and heated. Each of the modes (1) to (4) and the hot water supply / additional heating operation is performed based on the set values and commands input from the operation panel 15, detection values from the detection sensors E and F, and the like.

[Effects of the Invention] As described above, the present invention allows the remaining hot water to be heated by the additional heating device and injected into the washing machine by the circulation pump, so that the conventional device does not consume extra fuel and can be used until the water is injected. There is no need for waiting time, which is convenient. In addition, when hot water is not required, the remaining hot water can be poured into a washing machine without heating by a circulation pump without heating, which is economical. In addition, since tap water can be injected as it is or as hot water, rinsing with clean hot water or water can be freely performed, and the water flow can be heated according to the necessity of hot water, which is economical. For example, it is possible to selectively use hot water pouring only when using a detergent such as a biodetergent whose cleaning effect is remarkably improved with warm water, which is very convenient. Further, since the water injection mode is switched based on the presence or absence of the remaining hot water in the bathtub, the temperature of the remaining hot water, and the presence or absence of the hot water request, the user does not need to separately check the remaining hot water, which is convenient.
