Embodiment 1

[0063] combine figure 1 with Figure 9 As shown, the embodiment of the first aspect of the present invention proposes a water heater control method. The water heater includes a burner, a fan, a gas proportional valve and a pressure detection device arranged at the gas outlet of the gas proportional valve. Delivery air, water heater control methods include:

[0064] Step S102, controlling the pressure detection device to obtain the gas outlet pressure value of the gas proportional valve;

[0065] Step S104, adjusting the opening of the gas proportional valve according to the gas outlet pressure value, and adjusting the speed of the fan according to the gas outlet pressure value.

[0066] The control method provided by the invention is used in a water heater, and the water heater includes a shell, and a heat exchanger, a burner and a fan are arranged in the shell. A combustion chamber is formed in the casing, and the burner and the heat exchanger are located in the combustion...

Embodiment 2

[0089] On the basis of Embodiment 1, the step of obtaining the output heat value of the water heater specifically includes: receiving the set target outlet water temperature value, inlet water temperature value, outlet water temperature value and inlet water flow value; The temperature value and the water flow value are calculated to obtain the output heat value.

[0090] Such as Figure 4 As shown, the control methods of the water heater include:

[0091] Step S402, receiving the set inlet water temperature value, outlet water temperature value and inlet water flow value;

[0092] In step S404, the output heat value is calculated according to the inlet water temperature value, the outlet water temperature value and the water flow value.

[0093] In this embodiment, the inlet water temperature value, the outlet water temperature value and the inlet water flow value are obtained, and the water temperature difference can be determined according to the inlet water temperature v...

Embodiment 3

[0100] In the above embodiment, the step of adjusting the speed of the fan according to the outlet pressure value specifically includes: obtaining the second target pressure interval, determining the third target pressure interval according to the second target pressure interval; A comparison result between the pressure range and the third target pressure range adjusts the speed of the fan; wherein, the minimum value of the third target pressure range is smaller than the minimum value of the second target pressure range, and the maximum value of the third target pressure range is greater than the second target pressure range the maximum value.

[0101] Such as Image 6 As shown, the control methods of the water heater include:

[0102] Step S602, controlling the pressure detection device to obtain the gas outlet pressure value of the gas proportional valve;

[0103] Step S604, obtaining the second target pressure interval, and determining the third target pressure interval acc...

Abstract

The invention provides a control method of a water heater, the water heater and a readable storage medium. The control method of the water heater comprises the following steps that a pressure detection device is controlled to obtain the gas outlet pressure value of a gas outlet of a gas proportional valve; and the opening degree of the gas proportional valve is adjusted according to the gas outletpressure value, and the rotating speed of a fan is also adjusted according to the gas outlet pressure value. The water heater can automatically adjust the opening degree of the gas proportional valveand the rotating speed of the fan, self-adjustment is achieved, and therefore a user does not need to adjust various parameters of the water heater, and the use convenience of the user to the water heater is improved. When the gas outlet pressure value is abnormal, it shows that the opening degree of the gas proportional valve and the rotating speed of the fan need to be adjusted, the output heatof the water heater can meet the use requirement of the user, gas combustion is more sufficient, harmful gas is prevented from being generated, the problems of vibration and squeal are avoided, and the safe use of the gas water heater is guaranteed.
