Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0029] First, introduce and explain several terms involved in this application:

[0030] The duty cycle refers to the ratio of the duration of the positive pulse to the total period of the pulse in an ideal pulse sequence (such as a square wave), which can be understood as the ratio of the power-on time to the total time. For example: a pulse sequence with a pulse width of 1 microsecond and a signal period of 4 microseconds has a duty cycle of 0.25.

[0031] PWM is the abbreviation of Pulse Width Modulation, which means pulse width modulation. It modulates the width of a ...

Abstract

The invention relates to a gas device and a control method thereof. The method comprises the steps that when an ignition instruction is received, the current voltage of a power source is obtained; if the obtained current voltage is smaller than the preset voltage threshold value, the power supply is controlled to supply power to the strong suction coil, so that the fuel gas passes through the electromagnetic valve; after the power supply supplies power to the strong suction coil for a first preset duration, the power supply is controlled to supply power to the maintaining coil and controlling the power supply to stop supplying power to the strong suction coil; and after the power supply stops supplying power to the strong suction coil, an igniter is started to ignite the fuel gas passing through the electromagnetic valve. According to the embodiment, when it is determined that the electric quantity of the power source is low, the power source is controlled to supply power to the strong suction coil, and the igniter is started after the strong suction coil is disconnected, it is avoided that two loads powered to be large currents are started at the same time, the output stability of the power source at the low electric quantity is guaranteed, the ignition success rate is increased, or power shortage caused by the fact that two loads powered on to be large currents are started at the same time is avoided, and the purpose of saving power is achieved.

Description

technical field [0001] The present application relates to the technical field of gas devices, in particular to a gas device and a control method thereof. Background technique [0002] Currently, gas appliances (for example, gas cookers and gas water heaters) include solenoid valves, igniters, and batteries. Among them, the solenoid valve is used to switch the gas. The solenoid valve includes two sets of coil drives, one set is a strong suction coil, which is used to drive the valve core to open the solenoid valve; the other set is a maintaining coil, which is used to keep the valve core open. The battery serves as the power source for the solenoid valve and the igniter, which is used to ignite the gas. [0003] However, when the battery power is low, the ignition success rate of the gas appliance is low or. Contents of the invention [0004] The present application aims at the shortcomings of the existing methods, and provides a gas device and its control method to solv...
