[0023] With the above technical scheme, the water temperature is set on the controller 113, when the user 125, the user 127 and the user 117 take a bath, the water faucet is first opened to wet the body, when the body is wet, the shower gel is needed, and the hot water faucet is closed for the purpose of saving water resources, when the water faucet is closed, the wall-mounted stove 119 also stops heating the cold water, when the user needs to wash the body, the water faucet is opened again, the wall-mounted stove is ignited, and the wall-mounted stove can effectively heat the cold water only after the water flow in the pipeline circulates for 10 seconds, during the 10 seconds of water flow circulation, the cold water flows through the wall-mounted stove 119 and the circulating pipeline, and enters the inner cavity of the constant temperature hot water circulator shell 1, at this time, the temperature sensing probe 109 in the constant temperature hot water circulator shell 1 transmits the sensed temperature data to the controller 113, when the temperature is lower than the set temperature of the controller 113, the controller 113 starts the electric heating pipe 107 to quickly heat the cold water, so that the cold water is quickly heated to the set temperature, at this time, there is no cold water in the hot water circulating pipe; when the user opens the water faucet once and then closes the hot water faucet, the controller 113 starts the brushless water pump 115 to suck the water in the return water pipe 112 back to the wall-mounted stove 119 for reheating, at the same time, the controller 113 also starts the electric heating pipe 107 to quickly heat the cold water, and after 1 minute, the hot water is discharged out of the constant temperature hot water when the hot water faucet is opened again. By setting the constant temperature hot water circulator at the bottom end of the wall-mounted stove, the water temperature can be constant, the hot water can be used twice without cold water or warm water, and the hot water can be heated immediately, so as to achieve the purpose of saving water resources.

[0024] In one embodiment, for the above-mentioned electric heating tube 107, the top end of the electric heating tube 107 is one centimeter away from the top cover 102, thereby prolonging the cold water heating length, increasing the cold water heating time, and thus making the cold water reach the top end of the hot water outlet pipe 116 just reach the set temperature; the top end of the hot water outlet pipe 116 is one centimeter away from the top cover 102, thereby increasing the time for cold water to reach the top end of the electric heating tube 107, thereby increasing the cold water heating time, and thus making the cold water reach the top end of the hot water outlet pipe 116 just reach the set temperature.

[0025] In one embodiment, for the above-mentioned cold water inlet pipe 106, the end of the cold water inlet pipe 106 is one centimeter away from the electric heating tube 107, thereby increasing the time for cold water to reach the top end of the electric heating tube 107, thereby increasing the cold water heating time, and thus making the cold water reach the top end of the hot water outlet pipe 116 just reach the set temperature.

[0026] In one embodiment, for the above-mentioned temperature sensing probe 109, the temperature sensing probe 109, brushless water pump 115, and electric heating tube 107 are all electrically connected to the controller 113.

[0027] In one embodiment, for the volume of the above-mentioned thermostatic hot water circulator shell 1, due to the limited installation space in the family, the volume of the thermostatic hot water circulator shell 1 can be set according to the following description, assuming that the power of the electric heating tube 107 is P, the ignition time of the wall-mounted stove is t, the mass of the cold water passing through the water pipe in t time is m, the set temperature of the controller is T, the temperature difference of the cold water heated to the set temperature T is Δt, and the temperature of the water pipe under the condition of no ice formation is 0 degrees,

[0028] That is, the maximum temperature difference is Δt = T - 0 = T

[0029] According to the formula Q = cmΔt, it is transformed as:

[0030] Pt = cvρ 水 Δt, v = Pt / cρ 水 Δt, the maximum required volume of the thermostatic hot water circulator can be calculated.

[0031] In summary, by virtue of the above technical scheme of the present application, when the user 125, the user 127 and the user 117 take a bath, the water faucet is first opened to wet the body, and when the body is wet, the shower gel is needed, and the hot water faucet is closed for the purpose of saving water resources. When the water faucet is closed, the wall-hanging stove 119 also stops heating the cold water. When the user needs to wash the body, the water faucet is opened again, and the wall-hanging stove is ignited. Only when the water flow in the pipeline circulates for 10 seconds, the wall-hanging stove can effectively heat the cold water. Within the 10 seconds of water flow circulation, the cold water flows through the wall-hanging stove 119 and the circulating pipeline, and enters the inner cavity of the thermostatic hot water circulator shell 1. At this time, the temperature sensing probe 109 in the thermostatic hot water circulator shell 1 transmits the sensed temperature data to the controller 113. When the temperature is lower than the set temperature of the controller 113, the controller 113 starts the electric heating pipe 107 to quickly heat the cold water, so that the cold water is quickly heated to the set temperature. At this time, there is no cold water in the hot water circulating pipeline. When the user opens the water faucet and then closes the hot water faucet, the controller 113 starts the brushless water pump 115 to pump the water in the return water pipe 112 back to the wall-hanging stove 119 for reheating. At the same time, the controller 113 also starts the electric heating pipe 107 to quickly heat the cold water. After 1 minute, the hot water is discharged when the hot water faucet is opened again.

[0032] Beneficial effects: By setting the thermostatic hot water circulator at the bottom end of the wall-hanging stove, the water temperature can be constant, the hot water can be used twice without cold water or warm water, and the hot water can be heated immediately, thereby achieving the purpose of saving water resources.

[0033] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
