Abstract

The invention discloses a gas distributor and a gas water heater comprising the same. The gas distributor includes: a housing; multiple chambers are arranged in the housing, and each chamber is correspondingly provided with an air inlet and a plurality of gas nozzles communicating with the chamber; each inlet The air port is provided with a valve seat, an elastic member and a valve plug, the valve plug is arranged on the fluid outflow side of the valve seat, and the elastic member is biased in a direction such that the valve plug abuts against the valve seat The elastic coefficients of the elastic parts in each of the air inlets of the valve plug are different. The gas distributor is provided with elastic members with different elastic coefficients in different chambers, so that different air inlets are opened according to different air pressures (or called "wind pressure"). In this way, there is no need to set solenoid valves, and the gas distribution Different segments can be automatically selected according to the air pressure, which greatly simplifies the control process and the overall structure of the gas distributor.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a gas distributor and a gas water heater containing it. Background technique [0002] At present, the gas distribution devices of gas water heaters mostly adopt a segmented structure, and the intake air of different segments is controlled by solenoid valves, and the solenoid valves are controlled by the main control unit of the gas water heater. The outlet water temperature is used to control the opening and closing of the solenoid valve. The gas distribution device needs to be equipped with a solenoid valve, and the gas water heater also needs to be equipped with a connection between the master control unit and the solenoid valve and a control program. See Chinese Invention Patent Publication CN202361649U. [0003] These lead to a relatively complicated internal structure of the gas water heater, and since the solenoid valve closes toward the gas outflow direction, the valve plug of...
