Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 and figure 2 As shown, a gas water heater control method that automatically adapts to multiple gas sources includes the following steps: 1) collecting the data of inlet water temperature, outlet water temperature, and water flow through the controller; Carry out calculation; 3) Automatically adjust the input current of the gas proportional valve and the speed of the variable speed fan according to the calculation data until the output heat load reaches the set value; 4) Store the input current of the gas proportional valve, the input voltage of the variable speed fan, and the variable speed Fan input current data.

[0018] Then the gas water heater exits the adjustment or keeps running according to the stored data parameter, and will also run according to this parameter in the future. If the air source is changed again, it can be readjusted ...

Abstract

The invention belongs to the technical field of the control of a gas water heater and discloses a control method for the gas water heater for automatically adapting to multiple gas sources. The control method comprises the following steps: 1) collecting the data of inlet water temperature, outlet water temperature and water flow by a controller; 2) calculating the data by the controller according to a preset formula; 3) automatically adjusting an input current of a gas proportional valve and a rotating speed of a speed-changing fan according to the calculated data, till an output heat load reaches a preset value; and 4) storing the data of the input current of the gas proportional valve, the input voltage of the speed-changing fan and the input current of the speed-changing fan at the moment. By improving the control method according to the invention, the gas water heater can adapt to multiple gas sources, without exchanging or improving the gas water heater, so that the cost of a user is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of gas water heater control, and in particular relates to a gas water heater control method automatically adapting to multiple gas sources. Background technique [0002] Existing gas water heaters can only use a single type of gas. When the gas water heater uses different types of gas sources, the user needs to repurchase the gas water heater with the corresponding gas source, or renovate the original gas water heater, and these solutions require the user to pay A lot of cost. Contents of the invention [0003] In order to solve the above-mentioned shortcomings in the prior art, the present invention designs a gas water heater control method that automatically adapts to multiple gas sources, so that the user does not need to replace or refit the gas water heater and can also apply to multiple gas sources. [0004] The specific solution of the present invention is: a gas water heater control method that au...
