specific Embodiment approach 1

[0027] Specific implementation mode one: the following combination Figure 1 to Figure 6 Describe this embodiment, the anti-dry burning device for gas cooker with self-generating function described in this embodiment, it includes a microprocessor 1, it also includes a thermocouple 2, a direct flame fuel cell group 3, a direction adjuster 4, and a thermal insulation body 5 and rechargeable battery 6,

[0028] The direct flame fuel cell group 3 is composed of a plurality of sheet-shaped direct flame fuel cell cells, and the plurality of sheet-shaped direct flame fuel cell cells are connected and fixed in series through stainless steel connectors;

[0029] The direct flame fuel cell group 3 is used to be placed in the flame of the gas cooker, the temperature measuring end of the thermocouple 2 is embedded in the heat preservation body 5, and the temperature measuring end of the thermocouple 2 is used to contact the temperature measuring point of the upper pot body of the cooker, ...

specific Embodiment approach 2

[0036] Specific implementation mode two: the following combination Figure 4 Describe this embodiment. This embodiment will further describe Embodiment 1. This embodiment also includes an alarm 7 , and the alarm signal input end of the alarm 7 is connected to the alarm signal output end of the microprocessor 1 .

[0037] The microprocessor 1 outputs an alarm signal by controlling the alarm 7, and the alarm 7 can realize the alarm by sounding a buzzer or flashing a light-emitting diode indicator light.

specific Embodiment approach 3

[0038] Embodiment 3: This embodiment further describes Embodiment 1 or 2. The thermal insulation body 5 described in this embodiment is a porous ceramic block, ceramic fiber block, silica brick, clay brick or magnesia brick.

[0039] The shape of the heat insulating body 5 can be cylindrical or cubic, and it has two functions: one is to prevent the temperature measuring end of the thermocouple 2 from contacting with the hot air flow, and the other is to increase the specific heat capacity of the thermocouple 2 and reduce the temperature signal. fluctuation.

[0040] The thermal insulation body 5 can be made of a poor conductor of heat, for example, solidified by refractory cotton plus a coagulant.

Abstract

The invention provides a gas cooker dry burning preventing device with a self power generation function, and belongs to the technical field of cooker dry burning prevention. The dry burning preventing device provided by the invention aims to solve the problem that an existing cooker dry burning preventing device is inconvenient to use due to the requirement for an external power source. A direct flame fuel cell of the gas cooker dry burning-preventing device is placed in a flame of the gas cooker; the temperature measuring end of a thermocouple is embedded in a thermal insulating body, and is used for being contacted with the temperature measurement point of a pot on the cooker; the thermocouple is arranged on a direction regulator; electric energy output by the direct flame fuel cell is used as working power supply to a microprocessor and is also used for providing charging power supply to a rechargeable battery; the power supply end of the rechargeable battery is connected with the power supply end of the microprocessor; the temperature signal acquisition end of the microprocessor is connected with the temperature signal output end of the thermocouple; a control signal output by the microprocessor is used for controlling a gas valve to be closed. The gas cooker dry burning preventing device is used for dry burning prevention of the gas cooker.

Description

technical field [0001] The invention relates to an anti-dry-burning device for gas cookers with self-generating function, and belongs to the technical field of anti-dry-burning for cookers. Background technique [0002] With the development of kitchen culture, various anti-dry cooking utensils have been born one after another. Anti-dry cooking utensils can complete the work of detecting dry-boiling, alarming and stopping dry-boiling. The principle is to collect the temperature of the pot body by placing the temperature sensor inside the cooker or close to the outside of the cooker, and then analyze the collected temperature information through a single-chip microcomputer. After it is judged to be dry burning, control the alarm device to alarm or directly cut off the power supply or gas source to achieve the purpose of preventing dry burning. The Chinese patent "Anti-dry Burning Gas Cooker", the publication number is CN202561827U, and the publication date is 20121128, disclo...
