Abstract

The invention provides an air inlet stop valve module, an automatic anti-freezing gas water heater and a control method of the automatic anti-freezing gas water heater, and relates to the technical field of water heaters. The valve body comprises a fluid flow channel, the fluid flow channel is provided with a first port and a second port, and the valve body is provided with a side connector; the stop block is provided with an air flow channel and is slidably connected to the side connector. The check block is in transmission connection with the driving piece, and the driving piece is used for driving the check block to slide inwards or outwards so that the check block can block or open the fluid flow channel; the fluid flow channel and the air flow channel are not communicated at the same time. The automatic anti-freezing gas water heater comprises a gas inlet stop valve module. Through the air inlet stop valve module, the situation that in the prior art, an automatic drainage anti-freezing water heater system cannot ensure that residual water in the heat exchanger is completely drained is relieved, and the technical effects that the residual water in the heat exchanger can be completely drained, and the heat exchanger is prevented from frost cracking are achieved.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to an intake shut-off valve module, an automatic antifreeze gas water heater and a control method thereof. Background technique [0002] After the gas water heater is used, there is usually residual water in the heat exchanger, the water inlet pipe and the water outlet pipe. In the case of low temperature in winter, the residual water is easy to freeze and cause the pipe to burst. In order to prevent the pipeline from bursting, the most commonly used methods are manual and automatic drainage and antifreeze. [0003] For example, when manual drainage is used for antifreeze, the existing gas water heater can manually adjust the drain plug to release the residual water in the heat exchanger. However, users often cannot find the manual in time or are not at home, and cannot perform drainage and antifreeze protection according to the operation process of the manual. [0004] F...
