Description

[Technical field]

[0001] The utility model relates to a gas stove which can prevent abnormal over-combustion. [Background technology]

[0002] In today's era of frequent smart electronic products, especially the invention of mobile phones, people forget to turn off the working gas stove because they answer calls or use mobile phones while cooking, causing the gas stove to over-burn, burn appliances, electronic components, and even cause fires and other accidents. In reality, such accidents happen from time to time, so some people set NTC contact thermostats on gas stoves to sense temperature and prevent dry burning, so as to cut off the gas source by controlling the valve to close at a certain temperature.

[0003] However, the use of NTC contact thermostat has obvious disadvantages:

[0004] 1. Application scenarios are limited: NTC contact thermostats are installed in the center of the burner and in contact with the bottom of the cooking utensil. Therefore, the flame of the burner center fire ring cannot be sprayed toward the center for combustion due to structural limitations.

[0005] 2. High cost: NTC contact thermostats have high manufacturing precision. Because they need to be used in high temperature scenarios, most of the thermistors used in existing NTC contact thermostats need to be imported.

[0006] Therefore, it is necessary to further improve the valve body of this structure. [Contents of the utility model]

[0007] The purpose of this utility model is to overcome the above-mentioned problems. We provide a safety device for preventing abnormal over-combustion of a gas stove. The safety device is not limited by the burner structure and has a low cost.

[0008] To achieve the above-mentioned purpose, the present invention provides a gas stove that prevents abnormal over-combustion, which includes a stove body, on which a burner head assembly, a gas pipe, a sudden jump thermostat and a valve body are arranged, the gas pipe is respectively connected to the burner head assembly and the valve body, the valve body is used to open or cut off the gas pipe, the sudden jump thermostat is installed inside the stove body and close to the burner head assembly, the temperature sensing end of the sudden jump thermostat contacts the panel of the stove body for temperature sensing, and when the temperature measured by the sudden jump thermostat reaches a preset value, the valve body cuts off the gas supply of the gas pipe.

[0009] In one or more embodiments, the panel is a glass panel or a sheet metal panel.

[0010] In one or more embodiments, the sudden jump thermostat is fixed to the lower end surface of the panel by silicone bonding.

[0011] In one or more embodiments, a touch-control operation circuit board is disposed in the stove body, and the touch-control operation circuit board is installed at the bottom of the panel, and the touch-control operation circuit board can be controlled by touching the panel.

[0012] In one or more embodiments, the sudden jump thermostat is electrically connected to a touch-operated circuit board, and when the sudden jump thermostat is triggered, the power supply of the touch-operated circuit board is cut off.

[0013] In one or more embodiments, a thermocouple is provided on the burner head assembly, and a sudden jump thermostat is electrically connected to the thermocouple and the valve body. When the sudden jump thermostat measures a temperature reaching a preset value, the sudden jump thermostat cuts off the thermoelectric potential of the thermocouple so that the valve body cuts off the gas pipe.

[0014] Compared with the background technology, the utility model has the following effect: the gas stove adopts a sudden jump thermostat for temperature monitoring, and the sudden jump thermostat is set at a panel position close to the burner head assembly, and the heat radiated from the burner head assembly to the panel is sensed to judge whether there is an abnormal over-combustion state, and the gas source is cut off in time. It has the advantages of low cost and is not limited by the burner structure.

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0019] Please see attached Figure 1-3The utility model provides a gas stove for preventing abnormal over-combustion, which comprises a stove body 1, on which a burner assembly, a gas pipe, a sudden jump thermostat 2 and a valve body 3 are arranged, the gas pipes are connected to the burner assembly and the valve body 3 respectively, and the valve body is used to open or cut off the gas pipe, the sudden jump thermostat 2 is installed inside the stove body 1 and close to the burner assembly, so as to better monitor the combustion temperature of the burner assembly, the temperature sensing end of the sudden jump thermostat 2 contacts the panel 4 of the stove body 1 for temperature sensing, and the valve body 3 opens or cuts off the gas pipe according to the temperature measured by the sudden jump thermostat 2. When the burner assembly heats the cooking utensil for cooking and the cooking utensil is in a dry-burning state, the cooking utensil heats up rapidly and radiates the high temperature around, and the panel is heated and transmitted to the sudden jump thermostat. When the temperature measured by the sudden jump thermostat reaches a preset value, the valve body cuts off the gas supply of the gas pipe.

[0020] The panel 4 is a glass panel or a sheet metal panel. The sheet metal panel and the glass panel are commonly used gas stove panels on the market, and the two materials are easily available on the market.
