Embodiment 1
[0064] An optional embodiment of the present invention will be described in detail below by taking a water heater as an example in conjunction with the accompanying drawings.
[0065] This embodiment provides a method for controlling the outlet water temperature that can realize automatic adjustment. figure 1 It is a flow chart of a method for controlling outlet water temperature according to an embodiment of the present invention, such as figure 1 As shown, the method includes:
[0066] S1, obtain hot water temperature and cold water temperature;
[0067] Wherein, the hot water temperature refers to the temperature of the hot water in the hot water pipeline of the water heater, and the cold water temperature refers to the temperature of the cold water in the cold water pipeline of the water heater. The above hot water temperature and cold water temperature.
[0068] S2. Determine the proportion of hot and cold water according to the preset outlet water temperature set valu...
Embodiment 2
[0078] This embodiment provides another outlet water temperature control method, which includes:
[0079] Step 1: Obtain the hot water temperature T1 in the hot water pipe and the cold water temperature T2 in the cold water pipe through the temperature sensor. The flow rate of hot water is m1, the flow rate of cold water is m2, and the flow rate of outlet water is m1+m2. The user setting of the water heater sets the outlet water temperature is T (T is the common outlet water temperature, 38≤T≤45℃), then the formula is: It can be deduced that: The ratio of cold water flow m1 to hot water flow m2 can be obtained, and the temperature adjustment module can be used to adjust the ratio of cold and hot water to realize the actual outlet water temperature adjustment;
[0080] Step 2: Acquire the actual outlet water temperature T3 of the first water use cycle D multiple times according to the preset time interval d through the temperature sensor, wherein the water use cycle D can be...
Embodiment 3
[0086] This embodiment provides a structural diagram of an outlet water temperature control device capable of automatic adjustment, Figure 5 It is a structural diagram of an outlet water temperature control device according to an embodiment of the present invention, such as Figure 5 As shown, the device includes:
[0087] The obtaining module 11 is used to obtain the hot water temperature and the cold water temperature; the control module 12 is used to determine the ratio of cold and hot water according to the preset outlet water temperature setting value, the hot water temperature and the cold water temperature, so that the outlet water The temperature reaches the set value of the outlet water temperature; the correction module 13 is used to correct the set value of the outlet water temperature according to the outlet water temperature and the set value of the outlet water temperature, and set the corrected outlet water temperature The value is transferred to the control m...
