Description

Technical Field

[0001] The invention relates to the technical field of stove equipment, in particular to a high-temperature protection and exhaust fan linkage device for a gas stove. Background Art

[0002] With the continuous advancement of modern kitchen technology and people's increasing requirements for cooking environments, gas stoves, as important kitchen appliances, have become a focus of consumer attention for their safety and intelligence. However, the use of gas stoves poses certain safety risks due to the high temperatures during cooking and possible unexpected situations, such as forgetting to turn off the flame.

[0003] (1) Existing gas stoves lack effective high-temperature protection measures. During cooking, if an unexpected situation causes the stove head to overheat, it may cause a fire or other safety accident. For example, if the oil in the pot overheats and catches fire, if timely measures are not taken, the fire may spread rapidly.

[0004] (2) Existing gas stoves are usually not linked to exhaust fans. The fumes and hot air generated during cooking cannot be exhausted in time, which not only affects the air quality in the kitchen but also harms human health. In addition, high temperatures can accelerate the aging and damage of gas stoves.

[0005] (3) Although some gas stoves have a temperature display function, they cannot automatically take protective measures based on the temperature. Users need to pay attention to temperature changes at all times and operate manually, which may lead to safety problems due to negligence in actual use.

[0006] (4) The safety performance of existing gas stoves mainly depends on the correct operation and vigilance of the user. If the user is negligent during use, such as forgetting to turn off the fire or leaving the kitchen without turning off the gas stove, serious safety accidents may occur. Summary of the Invention

The installed infrared temperature sensor 50 can monitor the temperature at the center of the stove head in real time and transmit the temperature information to the control box 40 internal control unit. The single chip microcomputer 43 on the control panel; the single chip microcomputer 43 processes the received temperature information. When the temperature is too high, on the one hand, the exhaust fan 31 is started by controlling the electromagnetic switch 42 connected to the output end of the single chip microcomputer 43, and the exhaust fan 31 on the side seat 30 is used to discharge the waste gas and heat generated by the high temperature in time to reduce the ambient temperature; on the other hand, the single chip microcomputer 43 outputs a control signal to close the solenoid valve 15 on the air inlet pipe 14, stop the gas input, and prevent safety accidents caused by excessive temperature; the side seat 30 not only provides an installation position for the exhaust fan 31, but also the temperature display screen 33 installed on the top of the outer wall on one side close to the stove body 10 can also display the monitored temperature in real time, so that the user can understand the temperature of the stove at any time; the control box 40 plays the role of protecting and integrating the control circuit to ensure the stable operation of the entire linkage device; in summary, the high temperature protection and exhaust fan linkage device of the gas stove can effectively improve the safety and reliability of the use of the gas stove.

[0040] Furthermore, a bracket 11 for placing the cooker is mounted on the stove body 10. Bracket 11 is coaxially arranged with the burner head 20. Made of cast iron, bracket 11 allows the cooker to be stably placed above the burner head 20, ensuring stability and safety during cooking. Bracket 11 is made of cast iron, which has good load-bearing capacity and durability, further extending the life of the cooker.

[0041] Specifically, shock-absorbing bases 13 are mounted at each of the four corners of the bottom of the stove body 10. These bases are made of high-temperature-resistant rubber and are 5-10 mm tall. This reduces vibration and noise during cooking, improving the comfort of the cooking environment. Furthermore, the high-temperature-resistant rubber ensures that the shock-absorbing bases 13 maintain stable performance even in high-temperature environments, extending the life of the stove body.

[0042] The bottom of the side stand 30 is equipped with a mounting socket 34 that plugs into the side wall of the stove body 10. The top surface of the stove body 10 is equipped with at least two sets of fixing screws 12 for fixing the mounting socket 34. The top surface of the fixing screws 12 is flush with the top surface of the stove body 10.

The stainless steel mesh material makes the protective nets 32 have excellent corrosion resistance and durability, further improving the service life of the exhaust fan 31.

[0044] Furthermore, a data cable 41 is installed at the output end of the control box 40. The end of the data cable 41 is fitted with a plug connector for plugging into the bottom of the side base 30. The bottom of the side base 30 features an insertion slot 35 that is sized and compatible with the plug connector of the data cable 41, making the connection between the control box 40 and the side base 30 more flexible and convenient. The design of the plug connector ensures a more secure data cable connection, preventing malfunctions caused by a loose connection. Furthermore, the provision of the insertion slot 35 makes installation and removal of the data cable 41 easier and quicker.

[0045] It is worth noting that microcontroller 43 is an AT89S52, which gives the control system higher performance and reliability. The AT89S52 microcontroller has rich functions and good stability, meeting the control requirements of the gas stove high-temperature protection and exhaust fan linkage device, improving the intelligence level and operational efficiency of the entire system.

[0046] The working principle of the high temperature protection and exhaust fan linkage device of the gas stove:

[0047] First, gas is introduced into the cooker body 10 through the gas inlet pipe 14 to provide fuel for the burner 20. During the cooking process, the infrared temperature sensor 50 at the center of the burner 20 monitors the temperature in real time and transmits the temperature information to the single-chip microcomputer 43 on the control panel in the control box 40.

[0048] If the temperature is normal, the device continues to operate normally; when the temperature rises to a certain level, the single-chip microcomputer 43 performs processing; on the one hand, the output end of the single-chip microcomputer 43 controls the exhaust fan 31 on the side seat 30 to start through the electromagnetic switch 42, and the exhaust fan 31 starts working to discharge the surrounding hot air and exhaust gas; on the other hand, the single-chip microcomputer 43 outputs a control signal to close the electromagnetic valve 15 on the air inlet pipe 14, stop the gas input, and prevent the temperature from further rising and causing danger; at the same time, the temperature display screen 33 on the top of the outer wall of the side seat 30 close to the stove body 10 displays the current temperature in real time, making it convenient for users to understand the situation.

[0049] When the temperature of the cookware on the gas stove reaches the set temperature, generally set at around 70°C, the exhaust fan 31 automatically turns on and the temperature can be freely adjusted; when the temperature of the cookware on the gas stove is too high, the gas stove automatically turns off, and the high-temperature flameout temperature can be freely adjusted, generally between 220°C and 300°C; the control signal of the single-chip microcomputer 43 is input by the infrared temperature sensor 50, and the controller is connected to the switching circuit of the solenoid valve 15 to control the gas supply to the gas stove.
