Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to a built-in safety protection stove capable of realizing multiple timing functions. Background Art

[0002] With the continuous progress of society and the improvement of people's living standards, gas stoves are becoming increasingly popular in households. However, existing gas stoves generally have some problems and hidden dangers, especially in terms of safety and intelligence. Specifically, existing gas stoves lack effective timing control functions. When using gas stoves, users often need to manually control the heat and time when cooking. This can easily lead to dry burning problems due to negligence or accidents, resulting in safety hazards and energy waste.

[0003] Dry cooking occurs when a gas stove is left running for an extended period without liquid or ingredients, causing the pot's temperature to rise rapidly, potentially damaging the cookware or even causing a fire. Existing gas stoves typically rely on manual adjustments to power and cooking time, lacking automated control. Even the slightest negligence can lead to dry cooking accidents.

[0004] Furthermore, existing gas stoves have limited functions for power adjustment and timing, lacking intelligent control methods. For example, when users need to cook at different power levels, they must constantly monitor the power level and manually adjust it. This not only increases the complexity of the user's operation but also fails to ensure cooking accuracy and consistency. Therefore, further improvements are necessary. Utility Model Content

[0007] Furthermore: the detector is a potentiometer connected to the valve stem.

[0008] Furthermore: the detector is an encoder connected to the valve stem.

[0009] Furthermore: the valve stem passes through the bottom of the valve body, and the detector is installed at the bottom of the valve body.

[0010] Furthermore: the main control system has a built-in timing circuit, and the main control system sets a corresponding countdown to close the solenoid valve according to the detection value of the detector.

[0011] Furthermore: in the main control system, when the detector detects that the valve stem rotation angle is 75°-105°, the timing circuit automatically closes the solenoid valve after a 30-minute countdown.

[0012] Furthermore: in the main control system, when the detector detects that the valve stem rotation angle is 45-75° and 105°-175°, the timing circuit automatically closes the solenoid valve after a countdown of 60 minutes.

[0013] Furthermore: in the main control system, when the detector detects that the valve stem rotation angle is 175°-230°, the timing circuit automatically closes the solenoid valve after a countdown of 90 minutes.

[0021] The present invention is further described below in conjunction with the accompanying drawings. A safety protection cooker with a built-in function capable of realizing multiple timing functions comprises a bottom shell 1 and a panel 2 covering the surface thereof, wherein a mounting cavity is formed between the bottom shell 1 and the panel 2, wherein a burner 3 is mounted in the mounting cavity, the burner 3 being located at the bottom of a heat dissipation hole on the panel 2, and a flame distributor 4 and a stove frame 5 being mounted above the burner 3; the burner 3 being connected to a gas valve 6, which provides mixed gas for combustion to the burner 3; the gas valve 6 comprising a valve body 61 and a valve stem 62, the valve stem 62 driving a valve core located within the valve body 61 to move, thereby adjusting the firepower; the valve stem 62 being further connected to a detector 7, which is connected to a main control system 9, and which provides the main control system 9 with feedback on the firepower by detecting the rotational position of the valve stem 62; and the gas valve 6 being further provided with a solenoid valve 8, which is used to open and close the gas path and is electrically connected to the main control system 9.

[0022] In one embodiment, the detector 7 is a potentiometer connected to the valve stem 62 .

[0023] In one embodiment, the detector 7 is an encoder connected to the valve stem 62 .

[0024] In one embodiment, the valve stem 62 passes through the bottom of the valve body 61 , and the detector 7 is installed at the bottom of the valve body 61 .

[0025] In one embodiment, the main control system 9 has a built-in timing circuit, and the main control system 9 sets a corresponding countdown to close the solenoid valve 8 according to the detection value of the detector 7.

[0026] In one embodiment, in the main control system 9, when the detector 7 detects that the rotation angle of the valve stem 62 is 75°-105°, the timing circuit automatically closes the solenoid valve 8 after counting down for 30 minutes.

[0027] In one embodiment, in the main control system 9, when the detector 7 detects that the rotation angle of the valve stem 62 is 45-75° and 105°-175°, the timing circuit automatically closes the solenoid valve 8 after counting down for 60 minutes.

[0028] In one embodiment, in the main control system 9, when the detector 7 detects that the rotation angle of the valve stem 62 is 175°-230°, the timing circuit automatically closes the solenoid valve 8 after counting down for 90 minutes.

[0029] Working Principle: This stove consists of a base housing and a panel covering it. A mounting cavity is formed between the base and panel, housing the burner. The burner is located below the heat dissipation holes on the panel, and a flame distributor and a stove stand are mounted above the burner. The burner is connected to a gas valve, which consists of a valve body and a valve stem. The valve stem drives the valve core inside the valve body to adjust the heat output.

[0030] The valve stem is connected to a detector that provides feedback on the power level by detecting the valve stem's rotational position. The detector, which can be a potentiometer, encoder, or other detection method, is mounted on the bottom of the valve stem. When the gas furnace is operating, the detector transmits the detected power level information to the main control system, which then processes and controls the power level accordingly.

[0031] The main control system has a built-in timing circuit that can set a corresponding countdown based on the feedback value of the detector. When it detects that the valve stem rotation angle is within a specific range, the timing circuit starts counting down.

[0032] When the countdown time is reached, the main control system controls the solenoid valve to automatically shut off the gas supply to ensure safety.

[0033] For example, when the valve stem rotation angle is detected to be 75°-105°, the system identifies it as high fire mode, and the timing circuit automatically closes the solenoid valve after a 30-minute countdown; when the valve stem rotation angle is detected to be 45°-75° and 105°-175°, the system identifies it as medium fire mode, and the countdown is 60 minutes; when the valve stem rotation angle is detected to be 175°-230°, the system identifies it as low fire mode, and the countdown is 90 minutes.

[0034] Compared with traditional technology, the detector monitors the fire power in real time and feeds back the fire power information to the main control system. The main control system sets a variety of countdown functions according to different fire power states, which can ensure both cooking effects and fire safety.

[0035] The stove of this utility model is not only suitable for home kitchens, but also can be used in commercial kitchens such as restaurants and hotels, with broad market application prospects. It is compatible with existing gas stove systems, allowing users to upgrade without large-scale renovations, which improves the market acceptance of the product.

[0036] In summary, this stove has significant technical advantages in terms of safety, intelligence, versatility and structural design, and can effectively meet the needs of modern families and commercial kitchens for efficient, safe and intelligent stoves, so it can be widely promoted and used.

The above embodiments and descriptions are merely illustrative of the principles of the present invention.
