Claims

[Scope of claim for utility model registration] A water heater 2 to which a bathtub 4 is connected via piping on the downstream side;
A hot water filling device comprising a preliminary hot water supply means such as a solar water heater 1 which is connected via piping to the upstream side of the water heater 2, and a hot water temperature setting device 52 that sets the temperature of hot water to be supplied from the water heater 2 to the bathtub 4. A cold water circuit 7 supplies cold water to the bathtub 4, a cold water temperature sensor 71 detects the temperature of the cold water supplied from the cold water circuit 7, and a cold water temperature sensor 71 detects the temperature of the cold water supplied from the cold water circuit 7, and a cold water temperature sensor 71 detects the temperature of the cold water supplied from the cold water circuit 7. A hot water temperature sensor 12 that detects the temperature compares the detected temperature of the hot water temperature sensor 12 with the hot water filling temperature set by the hot water temperature setting device 52, and if the former detected temperature is higher than the latter hot water filling temperature, the water is lukewarm. Temperature comparison means 6 that outputs a request signal, and required hot water amount calculation means 8 that determines the required amount of hot water LH to be poured into the bathtub 4 from the preliminary hot water supply means such as the solar water heater 1 using the following calculation formula.
and the temperature of the hot water supplied from the preliminary hot water supply means such as the solar water heater 1, which is detected by the hot water temperature sensor 12, is T.
H, the temperature of the water supplied from the cold water circuit 7 detected by the cold water temperature sensor 71 is TC, the target water volume for hot water filling is LO,
When the hot water filling temperature set by the hot water temperature setting device 52 is taken as TO, the required hot water amount calculation means 8 calculates:
Required amount of hot water LH=LO×(TO-TC)/(TH
-TC), and when a lukewarm request signal is output from the temperature comparison means 6,
Hot water is filled until the total amount of hot water of the required hot water amount LH supplied from the preliminary hot water supply means such as the solar water heater 1 and the cold water supplied from the cold water circuit 7 reaches the hot water filling target water amount LO. Device. a water heater 2 to which a bathtub 4 is connected via piping on the downstream side;
In a hot water filling device equipped with a preliminary hot water supply means such as a solar hot water heater 1 which is connected via piping to the upstream side of the hot water heater 2, and a hot water temperature setting device 52 for setting the hot water filling temperature, A cold water circuit 7 connected to a flow path connecting a preliminary hot water supply means such as the water heater 1, etc., and a mixture amount adjustment valve 33 that adjusts the mixing ratio of hot water of the preliminary hot water supply means such as the solar water heater 1 and cold water of the cold water circuit 7. , a mixed water temperature sensor 36 disposed on the downstream side of the confluence of the cold water circuit 7 and a flow path led out from a preliminary hot water supply means such as the solar water heater 1; and the mixed water temperature sensor 36.
A mixed water temperature comparing means 60 is provided which compares the water temperature detected by the water temperature with the hot water filling temperature set by the hot water temperature setting device 52 and outputs a lukewarm request signal when the former detected water temperature is high. When the request signal is output, the mixing amount adjusting valve 33 is controlled to increase the amount of chilled water from the chilled water circuit 7 until the signal disappears, and conversely, the mixing amount adjusting valve 33 is controlled to increase the amount of cold water from the chilled water circuit 7.
The hot water filling device controls the mixing amount adjusting valve 33 to reduce the amount of cold water supplied from the cold water circuit 7 when the lukewarm request signal is not output from 0.
