Embodiment 1

[0040] This preferred embodiment discloses a gas water heater. like figure 1 and figure 2 As shown, the gas water heater includes a casing 1 and a water pipe 2 arranged in the casing 1, and a water flow server 3 is arranged 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 arranged to ensure that the water inlet volume can be adjusted in time when the water inlet volume changes, to ensure that it is always maintained at the set value, and to achieve the stability of the water inlet volume.

[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...

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 casing and a water pipe arranged in the casing, 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 inlet changes, the water flow The server is used to adjust the water intake to the set value. The control method is to continuously detect the water inflow. When the value of the inflow deviates from the set value, the water flow server is used to compensate the water flow, and the gas valve is adjusted synchronously to ensure a constant water temperature.

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

Abstract

The invention discloses a gas water heater and a control method thereof, belongs to the field of water heaters and the control method thereof, and is designed to solve problems such as difficult realization of existing devices. The gas water heater of the present invention 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, and the water flow servo includes a water flow sensor, a stepping motor and a water regulating valve core; The water flow servo is used to adjust the water intake to the set value. The control method of the present invention based on the above-mentioned gas water heater is to continuously detect the water intake, and use the water flow servo to compensate the water flow when the value of the water intake deviates from the set value, and the gas valve is synchronously adjusted to ensure a constant outlet water temperature. The gas water heater of the invention can maintain a stable water intake, thereby ensuring a stable temperature of the water outlet from the water heater. The control method based on the above-mentioned gas water heater of the present invention is convenient to use, easy to operate and more accurate to control the outlet water temperature.

Description

technical field [0001] The invention relates to the field of water heaters and a control method thereof, in particular to a gas water heater and a control method 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 that the water inlet is stable and the gas volume is stable. In daily use, because there are multiple faucets in the home, 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] In the existing gas water heater, a steady flow compensator is arranged on the water inlet pipeline to ensure a more stable water inlet. The defects are: there is no corresponding water heater control method; the steady flow compensator is a high-level concept, and it is difficult to realize without specific structure or component names.
