In particular, the present invention relates to a solar heat collection device that recovers waste heat from residual hot water in a bathtub.

The heat exchange section 55 of the thermal circulation circuit B, which communicates with Temperature sensing sensors 60 each detecting the temperature of the hot water are provided, and when the temperature of the bath water is higher than the temperature of the hot water, based on the sensing by the temperature sensing sensor 60,
A solar heat collection device has been proposed in which the waste heat of the bath water is stored in the heat storage tank 56 by switching the three-way valve 58 (
For example, see Japanese Utility Model Application Publication No. 57-121828).

収量はさらに減少するという問題があった。However, in this conventional solar heat collecting device, waste heat cannot be recovered effectively enough because the water in the heat storage tank 53 and the remaining hot water in the bathtub 56 exchange heat, and the water temperature in the heat storage tank 53 is There was a problem in that if the amount of waste heat recovered was still high (if the hot water supply load was low), the amount of waste heat recovered would further decrease.

3 through the second route pipe 88, and the heated tap water is passed through the water pipe 89 to the hot water storage tank 9 of the solar water heater 90.
A solar heat collection device has also been proposed in which hot water from a hot water storage tank 91 can be sent to a bathtub 81 through a hot water supply pipe 92 (for example, Utility Model Publication No. 62-17956).
(See Publication No. 8). In this solar heat collection device, the detector 93 can be manually set at the end of bathing to recover waste heat, or the detector 93 can be automatically set at an arbitrary predetermined time after the end of bathing to recover waste heat. It is something to do.

問題があった。[0005] However, in this solar heat collecting device, if a method is adopted in which the detector 93 is manually set, water will not be supplied to the hot water tank 91 if you forget to set it, and there will be no water in the hot water tank 91 the next morning. There is a problem in that heat is collected in a low or extremely low state, making it impossible to collect heat effectively, and there is also the risk of equipment damage due to dry heating. Also, if you adopt a method that automatically sets the time to a fixed time after bathing, there will be no inconvenience as described above, but since bathing times are irregular, it is necessary to set the time later to allow some time. There was a problem that efficient waste heat recovery was not possible.

A circulation circuit is provided in a heat exchange relationship with the water supply pipe, a circulation pump is provided in the circulation circuit that starts driving by a heat recovery switch and stops driving when the hot water storage tank becomes full of water, The solar heat collector is provided with a water supply control valve that opens when the circulation pump is driven and when the detector detects that the hot water storage tank is not full of water outside the time when the bathtub is used. A thermal device is provided by which the above objectives are achieved.

When it is detected that the hot water tank is not full of water outside of the time period when the hot water tank is filled with water, the water supply control valve opens and water is supplied to the hot water tank, so there is no need to forget to fill the hot water tank.

Indicates when is not pressed. First, the time period in which the bathtub 2 is used is set by the timer 22. The time period in which the bathtub 2 is used refers to the time period from when hot water starts being supplied to the bathtub 2 until the last person completes bathing, and in a normal household it is from around 16:00 to around 24:00. However, depending on the usage situation of the user, for example, from around 17:00 to around 22:00, or from around 15:00
The time can be set arbitrarily, such as from around 3:00 a.m. to around 3:00 a.m. During the time period when the bathtub 2 is used, the timer contact 23 is connected to the b side. That is, the water supply control valve 7 is opened from the power supply 25, and even if the water level in the hot water tank 3 falls and the float switch 6 is closed, the water supply control valve 7 does not open and water is not supplied to the hot water tank 3. Therefore, for example, during the time period when bathtub 2 is used from around 16:00 to around 24:00,
The hot water in the hot water storage tank 3 can be used as a load in the evening or for filling the bathtub 2 with hot water. In this way, when hot water is used as a load in the evening or to fill the bathtub 2 with hot water, the hot water storage tank 3 is empty or the water level is extremely low, and the float switch 6 is closed.
Relay contact R1 is also closed.

な構成にしてもよい。Next, after taking a bath, when the heat recovery switch 21 is pressed, the relay R2 is energized and the relay contact R2 is closed (
Relay R3 is originally energized and relay contact R
3 is closed), the circulation pump 9 and the water supply control valve 7 are opened, and water is supplied to the hot water tank 3 while exchanging heat between the remaining hot water in the bathtub 2 and the water supplied to the hot water tank 3 in the heat exchanger 11. When the hot water tank 3 becomes full, the float switch 6 opens and the relay contact R
1 and R2 open and the water supply control valve 7 closes, at the same time the circulation pump 9 stops. That is, water that has undergone heat exchange with the remaining hot water in the bathtub 2 can be supplied to the hot water storage tank 3. In addition, in order to prevent the circulation pump 9 from running idle, a configuration may be adopted in which the circulation pump 9 is not driven when the water level in the bathtub 2 is below a predetermined value.

The contact 23 switches to the a side. At this time, the water level in the hot water tank 3 is low and the float switch 6
is in a closed state, the relay R1 is energized, the relay contact R1 is closed, the water supply control valve 7 is opened, and water is supplied into the hot water tank 3.

による機器の破損もない。When the water level in the hot water storage tank 3 exceeds a predetermined value, the float switch 6 and relay contact R1 are opened and the water supply control valve 7 is closed. Therefore, the hot water storage tank 3 is full of water when heat collection starts the next day (for example, at 6 o'clock). In this way, when the bathtub 2 is not used, the float switch 6
By installing a water supply control valve 7 that opens when it is detected that the hot water storage tank 3 is not full, you will not forget to supply water to the hot water storage tank 3, and the next day's effective heat collection will be possible. No damage.

However, with the above configuration, even if hot water is supplied from the hot water tank 3 during the day, the water supply control valve 7 will open and water will be supplied to the hot water tank 3. The hot water storage tank 3 can be filled with water by the evening when the time period when the hot water tank 2 is used starts, and heat can be collected efficiently. Note that even if hot water is supplied from the hot water storage tank 3 during the day, water may not be supplied to the hot water storage tank 3.

The band may also be determined. When determining the time period in which the bathtub 2 is used using the solar radiation sensor, the time period may be set such that, for example, sunset is the start of this time period and sunrise is the end of this time period.
