Description

Technical Field

[0001] This utility model relates to an automatic start-stop gas stove, belonging to the field of gas stove technology. Background Technology

[0002] Commercial gas stoves are cooking equipment specifically designed for commercial catering establishments, such as restaurants, canteens, and hotel kitchens. They use natural gas as fuel and adjust the flame intensity via valves. However, to maximize efficiency, chefs typically don't adjust the valves during cooking. This results in significant fuel waste during idle periods such as ingredient preparation, plating, and washing, increasing production costs. Furthermore, the hot burner inevitably comes into contact with cold water, and this rapid temperature change can cause the burner to crack and break. Since existing gas stoves have a one-piece burner structure, the entire unit must be replaced after damage, which is time-consuming, labor-intensive, and costly. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an automatic start-stop gas stove that can realize the automatic start and stop of the gas stove, and the burner has a split structure, which is convenient to replace and has low replacement cost.

[0004] The automatic start-stop gas stove of this utility model includes a gas stove platform with a split-type burner assembly installed on the platform. The split-type burner assembly includes a burner plate and a lower burner, with the burner plate located above the lower burner. The burner plate supports the cookware, and a burner head is installed at the center of the lower burner. The automatic start-stop gas stove also includes a flexible push rod assembly, which includes a push rod. One end of the push rod passes through the lower burner and contacts the bottom of the burner plate, while the other end of the push rod contacts a micro switch. The micro switch controls the opening and closing of the gas valve and the starting and stopping of the igniter.

[0005] The technical solution of this utility model is to provide an automatic start-stop gas stove, which is equipped with a burner plate and a lower burner basin. When a pot is placed on the burner plate, the pot presses down on the burner plate, causing the push rod to move down, the micro switch is turned on, the gas valve is opened, and the igniter is ignited at the same time, and the gas stove starts to work. After the pot is removed from the burner plate, the push rod moves up, the micro switch is turned off, the gas valve is closed, and the gas stove is turned off.

[0006] Preferably, the lower furnace basin has an annular protrusion on its top periphery to position the upper furnace plate and prevent it from shifting during use.

[0007] Preferably, the elastic push rod assembly further includes a component mounting plate and a spring. The component mounting plate is fixed below the gas stove. The component mounting plate has a through hole, through which the push rod is inserted. The spring is sleeved on the push rod. The push rod has a pressure plate, and the spring is clamped between the pressure plate and the component mounting plate.

[0008] Preferably, the bottom end of the push rod is provided with a switch contact piece, and the push rod contacts the contacts of the micro switch through the switch contact piece to increase the contact area with the contacts and ensure the stability of operation.

[0009] Preferably, the micro switch is fixed to the bottom of the gas stove via a switch mounting plate.

[0010] Preferably, the burner head is connected to a gas pipeline, and a gas valve is installed on the gas pipeline; an igniter is also installed on the burner head, and both the gas valve and the igniter are electrically connected to a micro switch.

[0011] The advantages of this utility model compared with the prior art are:

[0012] The automatic start-stop gas stove described in this utility model achieves automatic start-stop by setting a split burner assembly and cooperating with an elastic top rod assembly, so as to save fuel and reduce costs; at the same time, the split design of the burner plate and the lower burner plate makes it easy to replace the burner plate when it is damaged, and the replacement cost is low.

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.

[0021] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.

[0022] like Figures 1-5 As shown, this embodiment is achieved through the following technical solution: it includes a gas stove 1, on which a split-type burner assembly 2 is installed. The split-type burner assembly 2 includes a burner plate 21 and a lower burner 22, with the burner plate 21 located above the lower burner 22. The burner plate 21 is used to support cookware, and a burner head 6 is installed at the center below the lower burner 22. The automatic start-stop gas stove also includes an elastic push rod assembly 3, which includes a push rod 32. One end of the push rod 32 passes through the lower burner 22 and contacts the bottom of the burner plate 21, while the other end of the push rod 32 contacts a micro switch 5. The micro switch 5 is used to control the opening and closing of the gas valve and the starting and stopping of the igniter.

[0023] In this embodiment, the lower burner 22 has an annular protrusion 221 on its top periphery for positioning the upper burner plate 21 and preventing it from shifting during use. The elastic push rod assembly 3 also includes an assembly mounting plate 31 and a spring 33. The assembly mounting plate 31 is fixed below the gas stove 1 and has a through hole through which the push rod 32 passes. The spring 33 is sleeved on the push rod 32. A pressure plate 322 is provided on the push rod 32, and the spring 33 is clamped between the pressure plate 322 and the assembly mounting plate 31. A switch contact piece 321 is provided at the bottom of the push rod 32. The push rod 32 contacts the contact point of the micro switch 5 through the switch contact piece 321 to increase the contact area and ensure operational stability. The micro switch 5 is fixed below the gas stove 1 by the switch mounting plate 4. The burner head 6 is connected to a gas pipeline, and a gas valve is installed on the gas pipeline; the gas valve is a solenoid valve, and an igniter is also installed on the burner head 6. Both the gas valve and the igniter are electrically connected to the micro switch 5.

[0024] The working process of this utility model is as follows:

[0025] When cooking is needed, placing the pot on the burner plate 21 causes the pot to press down on the burner plate 21, causing the push rod 32 to move down. The switch contact piece 321 then presses down on the micro switch 5, turning it on and opening the gas valve. At the same time, the igniter ignites the gas stove, and the gas stove starts working. When the gas stove is not needed temporarily, removing the pot from the burner plate 21 causes the push rod 32 to move up and reset under the action of the spring 33. The micro switch 5 then disconnects, the gas valve closes, and the gas stove shuts off.

[0026] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
