Embodiment 1

[0046] This embodiment provides a control method for a water heater constant temperature system, which is applied to the water heater constant temperature system. The water heater constant temperature system includes a water tank and a water heater, and the water heater is connected to the water inlet of the water tank through a first water outlet pipe. Wherein, the water heater is a gas water heater, an electric water heater, or a heat pump water heater, etc., which is not specifically limited.

[0047] In an optional embodiment, after being heated by the water heater, the cold water flows into the water tank through the first water outlet pipe to be stored in the water tank for standby use.

[0048] like figure 1 As shown, the control method of the constant temperature system of the water heater provided in this embodiment specifically includes the following steps:

[0049] Step S100, if a user's boot command is received, execute one of steps S101-S103 according to the magn...

Embodiment 2

[0078] This embodiment provides a constant temperature system for a water heater, including a water tank, a water heater, a memory, a processor, and a computer program stored in the memory and operable on the processor. The water heater is connected to the water inlet of the water tank through a first The outlet pipe is connected, and the processor implements the control method described in Embodiment 1 when executing the computer program.

[0079] In an optional embodiment, the water outlet of the water tank is connected to the third water outlet pipe, and the constant temperature system of the water heater further includes:

[0080] In the first three-way valve, one water inlet is connected to the first water outlet pipe, and two water outlets are respectively connected to the water inlet and the second water outlet pipe;

[0081] In the second three-way valve, two water inlets are respectively connected to the second water outlet pipe and the water outlet, and one water out...

Abstract

The invention discloses a water heater constant temperature system and a control method thereof. The control method of the constant temperature system of the water heater includes: if the start-up command from the user is received, the following steps are performed: if the set target temperature is lower than the water temperature of the water tank, the water heater is controlled to operate at the target temperature, and the water heater and the water tank are controlled to move toward the water point Water supply; if the set target temperature is equal to the water temperature of the water tank, only control the water tank to supply water to the water point, and control the water heater to run according to the target temperature and fill water into the water tank when the water volume in the water tank is lower than a certain value; if the set target temperature If the water temperature is higher than the water tank, only control the water tank to supply water to the water point, and control the water heater to operate at the target temperature and fill the water tank; after the water heater operates at the target temperature for a period of time, only control the water heater to supply water to the water point. The invention can specifically reduce the influence of residual water on the outlet water temperature of the water point, and further solve the problem of hot and cold outlet water temperature.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a water heater constant temperature system and a control method thereof. Background technique [0002] With the improvement of people's living standards, the quality requirements for hot water use are also getting higher and higher. In the traditional circulating heating system, after the heating is completed, there will be alternating cold and hot water in the water pipe, and when the external water pressure fluctuates, there will also be intermittent cold and hot conditions. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the hot and cold water in the water pipe alternates after the heating of the traditional circulation heating system is completed, and when the external water pressure fluctuates, the water flowing out of the water heater is intermittently cold and hot. A water heater...
