Embodiment 1
[0034] see figure 1 and figure 2 , a control method for a gas water heater, comprising the steps of:
[0035] S1, collecting water flow data passing through the water flow sensor;
[0036] Specifically, each collection of water flow data is recorded as a[0], a[1], a[2], a[3]...a[n], where n≥99, and a[0] is the earliest For the collected water flow data, a[n] is the latest collected water flow data. In this embodiment, 100 times of water flow data are specifically collected, that is, the latest collected ground water flow data a[n] is a[99] ;
[0037] By collecting water flow data multiple times, it is possible to more accurately analyze whether the water flow sensor is stuck, control the decontamination device in time, clean and remove the sewage flow sensor, and prevent it from being stuck.
[0038] S2, comparing and analyzing the water flow data, and obtaining a water flow change value;
[0039] see figure 2 , specifically, each collection of water flow data is compa...
Embodiment 2
[0052] A water heater comprising:
[0053] The water flow sensor is used to receive the water flow signal and adjust the water flow signal;
[0054] The collection module is used to collect the water flow data of each water flow sensor;
[0055] The processing module compares the water flow data collected by the water flow sensor each time with the earliest collected water flow data a[0];
[0056] The control module receives the processing signal from the processing module, and controls the operation status of the decontamination device;
[0057] The decontamination device receives instructions from the control module and is used to clean and decontaminate the water flow sensor.
[0058] Specifically, the water flow sensor includes a magnetic rotor for sensing water flow signals
[0059]The cleaning and decontamination control method of the water flow sensor adopted in the water heater can prevent the water flow sensor from being stuck and affect the normal operation of the...

Abstract
The invention provides a control method of a gas water heater and the water heater applying the control method. The control method comprises the following steps that S1, water flow data of water passing through a water flow sensor are collected; S2, comparative analysis is carried out on the water flow data, and a water flow change value is obtained; and S3, according to the water flow change value, the operation state of a decontamination device is controlled, and the step S1 is performed again. The control method of circularly collecting the water flow data can prevent the phenomenon that the water flow sensor is stuck, and the water heater can be normally started.
Description
technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a control method of a gas water heater and a water heater using the same. Background technique [0002] Most water heaters have water flow sensors, which can sense water flow signals and adjust water flow. The role of magnetic rotors in water flow sensors is very important; however, in the process of using water flow sensors, since natural water contains more minerals or other impurities, due to The magnetic rotor is magnetic, which will make all kinds of impurities adhere to the surface of the magnetic rotor. When it is used for a long time or the water quality is poor, it is easy to cause the water flow signal sensed by the magnetic rotor to be too weak, causing the water heater to fail to start normally, that is, the water flow sensor is stuck. The dead phenomenon affects the user experience. Contents of the invention [0003] The object of the present invention ...
