Problems solved by technology

[0003] However, during the ignition process, if the user only presses the knob without rotating it, or presses and rotates without maintaining the pressing action, the ignition generally cannot be successful.
The ignition operation steps of this type of gas stove are cumbersome, and when the elderly use the gas stove, they often fail to ignite because they do not press in place or do not rotate after pressing or do not maintain after pressing and rotating.
At the same time, because the gas stove ignition and ventilation switch are integrated on the same knob, it is easy to misuse, that is, the user rotates and presses the knob but fails to ignite successfully. It is customary to maintain the pressing action and wait for the flame to appear. If the electric ignition fails, it will cause A certain amount of gas leakage will affect the life and property safety of users in serious cases

Embodiment 1

[0039] In this example, if figure 1 As shown, a gas stove includes a thermocouple, a pulser, an ignition needle, a gas pipeline, and a first valve body and a second valve body connected to the gas pipeline, and the second valve body is connected to the thermocouple and the second valve body respectively. The delayers are connected in series and opened by a switch structure independent of the first valve body. When the gas pipeline is turned on, the second valve body is subjected to the thermal electromotive force generated by the thermocouple within the time set by the delayer. The role is to keep the gas pipeline open.

[0040] In this embodiment, the switch structure of the second valve body is set independently of the first valve body, which reduces the air leakage caused by accidental operation. The opening time of the second valve body during the fire process, and when the gas is accidentally extinguished, the second valve body is controlled to close by the thermoelectri...

Embodiment 2

[0054] In this example, if figure 2 As shown, a control method of a gas stove is also provided, the first valve body is connected in series with the second valve body, and connected to the gas pipeline, and when the first valve body is opened, a delayer is connected to the opening The second valve body of the thermocouple and the second valve body of the thermocouple are ignited at the same time, so that the second valve body is kept open by the thermal electromotive force generated by the thermocouple within the setting time of the delayer.

[0055] In this embodiment, when the first valve body is opened, one-button ignition can be realized through the second switch, and it is not necessary to perform operations such as rotation, pressing, and pressing and maintaining when a single knob is used in the prior art, which simplifies the ignition steps At the same time, a delayer and a thermocouple are added to the second valve body to facilitate more accurate control of the on-o...

Abstract

The invention relates to the technical field of gas stoves, in particular to a gas stove and a control method thereof. The gas stove comprises a thermocouple, a pulse, an ignition needle, a gas pipeline, and a first valve body and a second valve body connected with the gas pipeline; the second valve body is serially connected with the thermocouple and a delay, and is controlled to open by a switchstructure independent from the first valve body; and under the condition of conducting the gas pipeline, the second valve body is acted by thermoelectromotive force generated by the thermocouple within time set by the delay to maintain conduction of the gas pipeline. The control method comprises common control of the first valve body and the second valve body and maintenance of the conduction ofthe gas pipeline under the continuous thermoelectromotive force effect generated by the thermocouple within time set by the delay. The gas stove is convenient to operate, safe in use and suitable forpopularization.

Description

technical field [0001] The invention relates to the technical field of gas stoves, in particular to a gas stove and a control method thereof. Background technique [0002] The ignition system of the existing gas cooker generally includes: a knob, a pulser, an ignition magnetic needle, a thermocouple and a solenoid valve connected with the thermocouple. When the user presses the knob, the pulsator starts to discharge, the ignition magnetic needle generates electric sparks, and then the user rotates the knob to open the cock valve channel. At this time, the gas in the burner is ignited, and the user keeps pressing until the flame burns stably. Stove ignition process. [0003] However, if the user only presses the knob but does not rotate it during the ignition process, or if the user presses and rotates without maintaining the pressing action, the ignition will generally fail. The ignition operation steps of this type of gas stove are relatively cumbersome, and when the elde...
