Embodiment 1

[0037] Embodiment one: if Figure 1 to Figure 4 As shown, this embodiment provides a constant temperature control method for a gas water heater, wherein the gas water heater includes a heat exchange system 1, a water inlet pipe 2 and a water outlet pipe 3, and the heat exchange system 1 is connected to the water inlet pipe 2 and the water outlet pipe 3 respectively. A bypass pipe 4 is provided between the water inlet pipe 2 and the water outlet pipe 3 to connect the water inlet of the water inlet pipe 2 with the water outlet of the water outlet pipe 3, and a first valve body 21 is arranged on the water inlet pipe 2, and the first valve body 21 For detecting and adjusting the water flow of the water inlet pipe 2 , a second valve body 41 is arranged on the bypass pipe 4 , and the second valve body 41 is used for detecting and adjusting the water flow of the bypass pipe 4 .

[0038] The gas water heater of this embodiment has a simple and compact structure, which can effectively ...

Embodiment 2

[0047] Embodiment two: if figure 1 , image 3 and 4 As shown, this embodiment provides a constant temperature control method applied to the above-mentioned gas water heater. The constant temperature control method specifically includes the following steps:

[0048] Step S101, during the normal operation of the gas water heater, restart the gas water heater when the water inlet pipe stops entering water and after a period of time.

[0049] In this embodiment, the user turns off the gas water heater to temporarily stop the water supply after bathing for the first time, and restarts the gas water heater to work when the user needs to continue bathing after a period of time. Step state to close the first valve body.

[0050] Step S102, detecting the water flow rate of the water inlet pipe, and collecting the water outlet temperature of the water outlet pipe at the same time.

[0051] Step S103, compare the obtained water flow of the water inlet pipe with the minimum starting w...

Abstract

The invention discloses a constant temperature control method of a gas water heater. The constant temperature control method comprises the following steps: in the normal operation process of the gas water heater, when the water inlet pipe stops water intake, restart the gas water heater; detect the water flow rate of the water inlet pipe, and simultaneously collect Outlet water temperature of the water outlet pipe; compare the obtained water flow of the water inlet pipe with the minimum starting water flow, the collected water outlet temperature of the water outlet pipe and the preset target temperature, and control the first valve body and the second valve according to the comparison results Body action to keep the water flowing out through the outlet pipe at a constant temperature. The method is simple and feasible, and can effectively solve the problem of excessive water temperature fluctuations during the use of the water heater.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a constant temperature control method for a gas water heater. Background technique [0002] In the related art, most of the gas water heaters (except the circulation system models) need a period of time to reach the previous bathing temperature after the water valve is closed and restarted during use, which affects the bathing comfort of the user. [0003] Whether the water heater has a constant temperature has always been the most critical factor to measure the excellent performance of the water heater. The constant temperature performance is the most direct experience for the user's comfort. At present, the constant temperature performance of gas-fired water heaters is mainly guaranteed by two aspects: First, the constant temperature algorithm of the water heater matches the best heat load range by calculating the temperature difference between the inlet and outlet w...
