Embodiment 1

[0040] This preferred embodiment discloses a gas water heater. Such as figure 1 with figure 2 As shown, the gas water heater includes a housing 1 and a water pipe 2 arranged in the housing 1. A water flow servo 3 is provided at the water inlet end of the water pipe 2. The water flow servo 3 includes a water flow sensor 31, a stepping motor 32, Water regulating valve core 33 and temperature sensor 34.

[0041] At the water inlet end of the water pipe 2, a water flow server 3 with the function of monitoring and adjusting the water volume is provided to ensure that the water intake can be adjusted in time when the water intake changes, and it is always maintained at the set value to realize the stability of the water intake.

[0042] The stepping motor 32 is arranged on one end of the water regulating valve core 33; the water flow sensor 31 is arranged on the inner wall of the water inlet end of the water pipe 2, and the water regulating valve core 33 is arranged on the channe...

Embodiment 2

[0061] This preferred embodiment discloses a gas water heater, the structure and control method of which are basically the same as those of the first preferred embodiment. The gas water heater includes a shell and a water pipe arranged in the shell, and a water flow servo is arranged at the water inlet end of the water pipe; the water flow servo includes a water flow sensor, a stepping motor and a water regulating valve core; when the water inflow changes, the water flow The servo is used to adjust the water intake to the set value. The control method is to continuously detect the water intake. When the value of the water intake deviates from the set value, the water flow servo is used to compensate the water flow, and the gas valve is adjusted synchronously to ensure a constant outlet water temperature.

[0062] The difference is that the water flow servo does not include a temperature sensor, and the water flow sensor and stepper motor can be used to adjust the water intake....

Abstract

The invention discloses a gas water heater and a control method thereof, belongs to the field of water heaters and control methods thereof, and is designed for solving such problems as difficult realization in a traditional device. The gas water heater comprises a shell, and a water pipe arranged in the shell; a water current server is arranged at a water inlet end of the water pipe, and includes a water current sensor, a stepper motor and a water adjusting valve element; and when the water inlet quantity is changed, the water current server is used for adjusting the water inlet quantity to reach a set value. The control method based on the gas water heater continuously detects the water inlet quantity; when the numerical value of the water inlet quantity is deviated from the set value, the water current server is used for compensating the water flow; and a gas valve synchronously adjusts to guarantee constant water outlet temperature. The gas water heater can keep stable water inlet quantity to guarantee stable water outlet temperature thereof. The control method based on the gas water heater is convenient for use, easy to operate and more precise in control of the water outlet temperature.

Description

technical field [0001] The invention relates to the field of water heaters and control methods thereof, in particular to a gas water heater and control methods thereof. Background technique [0002] Gas water heaters use gas to heat water. In order to control the outlet water temperature, it is necessary to ensure a stable water intake and a stable gas flow. In daily use, because there are multiple faucets in the family, when other faucets discharge water, the water intake at the water heater will change, which will lead to large changes in the outlet water temperature and poor user experience. [0003] An existing gas water heater is provided with a steady flow compensator on the water inlet pipeline to ensure more stable water inlet. The disadvantages are: there is no corresponding water heater control method; the steady flow compensator is a high-level concept, and it is difficult to realize due to the lack of specific structures or names of components.
