[0061] In the first embodiment of the present invention, a constant temperature control method for a water heater, the bypass pipe is connected between the water inlet main pipe and the water outlet main pipe of the water heater, such as figure 2 As shown, the method includes the following specific steps:

[0062] Step S101, setting a first water server on the main pipe of the water inlet, except for the part diverted by the bypass pipe, the rest of the total water inlet flow of the water heater flows through the first water server;

[0063] Step S102, when the total inflow water flow fluctuates, adjust the bypass ratio of the water flow by controlling the first water servo to maintain a constant temperature of the water outflow from the water heater.

[0064] Specifically, the method further includes: setting a second water servo for detecting the total water inlet flow on the main pipe of the water inlet, and the total water inlet flow flowing through the second water servo...

[0071] In the second embodiment of the present invention, a constant temperature control method for a water heater, the bypass pipe is connected between the water inlet main pipe and the water outlet main pipe of the water heater, such as image 3 As shown, the method includes the following specific steps:

[0072] Step S201, setting a first water server on the main pipe of the water inlet, except for the part diverted by the bypass pipe, the rest of the total water inlet flow of the water heater flows through the first water server;

[0073] Step S202, when the set temperature of the water heater changes, adjust the bypass ratio of the water flow by controlling the first water servo to maintain a constant temperature of the outlet water of the water heater.

[0074] Specifically, step S102 includes:

[0075] When the set temperature of the water heater increases, the target value of the water flow of the main road where the first water server is located is determined based o...

[0081] The third embodiment of the present invention is a method for constant temperature control of a water heater. The method in this embodiment is substantially the same as that in the first or second embodiment, the only difference being that the method in this embodiment also includes:

[0082] When the total water inlet flow fluctuates, the total water inlet flow of the water heater is adjusted by controlling the second water servo to help maintain a constant temperature of the outlet water of the water heater.

[0083] Specifically, when the water flow fluctuates, the total water inlet flow of the water heater is adjusted by controlling the second water servo to help maintain a constant temperature of the water outlet of the water heater, including:

[0084] When the second water servo detects that the total water inlet flow increases, the opening of the second water servo is reduced so that the total water inlet flow returns to the state before the increase;

Abstract

The invention provides a constant-temperature control method and device for a water heater. A bypass tube is bridged between a main water inlet pipeline and a main water outlet pipeline of the water heater. The method comprises that a first water server is arranged on the main water inlet pipeline; according to the water flow, all the incoming water of the water heater, excepting the water flowing through the bypass tube, flows through the first water server; when the total incoming water flow fluctuates or the set temperature of the water heater changes, the first water server can be controlled to adjust the bypassing ratio of the water flow so as to keep the constant temperature of the outgoing water of the water heater. According to the constant-temperature control method and device for the water heater, the water server capable of accurately adjusting the bypassing ratio of the water flow is additionally arranged on the water heater equipped with the bypass tube, so that the time of a gas water heater reaching the constant temperature can be further decreased, the problem of temperature delay can be solved, and the constant temperature performance of the gas water heater can be improved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a constant temperature control method and device for a water heater. Background technique [0002] With the rapid development of social economy, the improvement of people's living standards has a higher pursuit of quality of life. At present, gas water heaters generally have problems of water stoppage, temperature rise, condensate water and temperature lag, especially for high-power machines. ; Electric water heater also has the problem of stopping water temperature rise. [0003] In order to better improve the constant temperature performance of the water heater, the solution for the existing gas water heater is: [0004] 1. If figure 1 As shown, adding a bypass pipe solves the problem of excessive temperature rise and condensed water without water supply. However, the proportion of water flowing into the bypass pipe is fixed, and the required water proportion cannot be...
