Description

Technical Field

[0001] This utility model relates to the field of catering production, and in particular to a gas-fired cooking stove with flameout protection. Background Technology

[0002] Traditional gas-fired cooking stoves are widely used in commercial or canteen environments, but they pose significant safety hazards. When cooking with large-capacity pots, the soup often boils over or strong winds cause the flame to go out unexpectedly, making it impossible to quickly stop the gas leak. Furthermore, the continuously leaking gas can easily spread through the open exhaust vent, which may cause a deflagration accident when it comes into contact with an open flame or high temperature. The exhaust vent usually does not have a quick sealing mechanism, and the residual gas in the combustion chamber cannot be effectively isolated after the flame goes out.

[0003] Therefore, in order to address the above problems, a gas-fired cooking stove with flameout protection is now being developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices during use, this utility model provides a gas-fired cooking stove with flameout protection.

[0005] The technical solution of this utility model is:

[0006] A gas-fired cooking stove with flameout protection includes a large cooking stove, an air inlet pipe installed on the right side of the large cooking stove, an igniter installed at the bottom of the large cooking stove, annularly distributed exhaust ports at the top of the large cooking stove, and an opening and closing mechanism on the large cooking stove for sealing the exhaust ports.

[0007] Furthermore, the opening and closing mechanism includes an opening and closing cover. Multiple opening and closing covers are rotatably connected to the upper part of the large stove. The opening and closing covers are used to seal the exhaust port. Each opening and closing cover is connected to a locking member through a drilled hole. The locking member has an assist block. The upper inner side of the large stove is provided with a limiting block corresponding to the number of locking members. The limiting block is used to block and limit the locking members.

[0008] Furthermore, it also includes a sealing assembly, which includes a pot lid, the pot lid being placed on top of the large stove, and the pot lid having a handle installed on top.

[0009] Furthermore, a ignition switch is rotatably installed on the front left side of the large cooking stove, and a firepower adjustment knob is rotatably connected to the front right side of the large cooking stove.

[0010] Furthermore, a sealing ring is provided on the inner side of each of the opening and closing covers.

[0011] Furthermore, the bottom outer side of the pot lid is provided with a fitting structure, which can be engaged with the upper edge of the large pot stove.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are:

[0013] This invention employs a dual protection mechanism that cuts off the gas supply via a solenoid valve and quickly locks the exhaust port, instantly isolating the gas leakage path and blocking the conditions for reignition, significantly improving the flameout safety level. The locking component, in conjunction with the limit block, ensures the sealing reliability and opening / closing stability of the cover. Attached Figure Description

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] A gas-fired cooking stove with flameout protection, such as Figures 1-4As shown, the appliance includes a large cooking stove 1. A ignition switch 2 is rotaryly mounted on the front left side of the large cooking stove 1. A flame control knob 3 is rotaryly connected to the front right side of the large cooking stove 1. An air intake pipe 4 is installed on the right side of the large cooking stove 1, and a solenoid valve 5 is installed on the air intake pipe 4. An igniter 6 is installed at the bottom inside the large cooking stove 1. A ring of exhaust vents 7 is located at the top of the large cooking stove 1. An opening and closing mechanism 8 is installed on the large cooking stove 1 to seal the exhaust vents 7. The structure 8 includes an opening and closing cover 81. Multiple opening and closing covers 81 are rotatably connected to the upper part of the large pot stove 1. The opening and closing covers 81 are used to seal the exhaust port 7. Each opening and closing cover 81 is connected to a hole with a locking element 82. The locking element 82 has an assist block. The upper inner side of the large pot stove 1 is provided with a limit block 83 corresponding to the number of locking elements 82. The limit block 83 is used to block and limit the locking elements 82. A sealing ring 84 is provided on the inner side of each opening and closing cover 81.

[0021] It also includes a sealing component 9, which includes a pot lid 91. The pot lid 91 is placed on the top of the large pot stove 1. A handle 92 is installed on the top of the pot lid 91. The bottom outer side of the pot lid 91 is provided with a fitting structure 93, which can be engaged with the upper edge of the large pot stove 1.

[0022] It should be noted that before use, the pot lid 91 is snapped onto the upper edge of the large pot stove 1 through the interlocking structure 93 on the outer bottom to form an auxiliary seal. When igniting, the ignition switch 2 is turned counterclockwise, the solenoid valve 5 is opened to allow gas to enter from the gas inlet pipe 4, and the igniter 6 is started simultaneously to ignite the gas. The flame burns in the stove cavity to generate heat and high-temperature flue gas. Then, the locking part 82 is turned to disengage from the limit block 83, so that the opening and closing cover 81 is kept in the open position, and the flue gas can be smoothly discharged from the annularly distributed exhaust port 7. The sealing ring 84 on the inner side of the opening and closing cover 81 can tightly fit the edge of the exhaust port 7 when closed to ensure sealing. The firepower is adjusted by rotating the firepower adjustment knob 3 to adjust the gas flow.

[0023] When the flame is accidentally extinguished (e.g., soup spills out and extinguishes the flame), immediately shut off the solenoid valve 5 to stop the gas supply. At the same time, the high-temperature smoke disappears. Quickly rotate the lid 81 to reset and close it. During the rotation, the locking element 82 is blocked and locked by the limit block. At this time, the sealing ring 84 presses tightly against the exhaust port 7 to form a physical seal. The dual protection mechanism jointly prevents gas leakage and air from entering the stove cavity, eliminating the risk of gas accumulation and explosion. When cleaning or inspecting, drive the locking element 82 to disengage from the limit block 83 to lift the lid 81. To restart the flame, you must first manually close and lock the lid 81, reset the ignition switch 2 to the off position, and then operate according to the normal ignition procedure to forcibly confirm the sealing status. The snap-fit ​​seal of the pot lid 91 further reduces heat loss and reduces the possibility of reignition, improving safety and thermal efficiency.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
