Description

Technical Field

[0001] This utility model relates to gas stoves, and in particular to an energy-saving gas stove. Background Technology

[0002] A gas stove is a kitchen cooking appliance that uses combustible gas (such as natural gas, liquefied petroleum gas, or manufactured gas) as fuel to produce a flame that directly heats cookware. Its main function is to provide a controllable heat source for home or commercial kitchens, used for various cooking methods such as boiling, stir-frying, stewing, and pan-frying.

[0003] Existing gas stoves mainly consist of a gas supply system, a combustion system, an ignition system, a control system, and a support system. With technological advancements, the combustion system of gas stoves has been optimized to be highly efficient, with the combustion efficiency of natural gas now consistently above 75% (physically characterized by a pale blue flame and a stable flame state). This means that there is little room left to improve the combustion system to achieve energy savings.

[0004] However, it's important to know that after cooking a dish, we usually need to wash the pan to prevent flavors from mixing. During this process, we often don't turn down the gas stove flame (because the washing time is relatively short, usually between 15 and 30 seconds, and the necessity of flame adjustment is often overlooked). This habit results in the gas stove running at high flame, wasting little energy in the short term, but accumulating over a year. Therefore, if the flame could be automatically adjusted (from high to low) after the pan is removed from the stove, energy savings would be achieved. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving gas stove to improve the energy waste caused by dry burning of gas stoves.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An energy-saving gas stove, including

[0008] ontology;

[0009] The burner head has an inner ring gas distribution pipe and an outer ring gas distribution pipe;

[0010] The valve body assembly is located in the main body, and the inner ring air distribution pipe and the outer ring air distribution pipe are connected to the valve body assembly;

[0011] A support bracket is mounted on the surface of the main body to support the pot;

[0012] The self-adjusting mechanism includes a valve assembly disposed on the outer ring gas distribution pipe and a trigger assembly disposed on the support. The trigger assembly is drivenly connected to the valve assembly so as to drive the valve assembly to close the outer ring gas distribution pipe after the pot is lifted away from the support.

[0013] Preferably, the valve assembly includes a sleeve, with an adjusting plate A coaxially disposed in the middle of the sleeve. The adjusting plate has evenly distributed through holes A. The adjusting plate A is fixedly connected to the sleeve via a connecting part. There is a gap between the front and rear end faces of the adjusting plate A and the inner end face of the sleeve. An adjusting plate B is rotatably disposed within this gap. The adjusting plate B has through holes B that are coaxially opposite to the through holes A. A radially extending lever A is disposed on the edge of the adjusting plate B. The lever A is drivenly connected to a triggering component. When the pot leaves the support, the triggering component moves the lever A to misalign the through holes A and B.

[0014] Preferably, the triggering component includes a guide rod that can move axially through the bracket and extend into the body. A return spring is provided at the upper end of the guide rod to apply an upward pushing return force to the guide rod. The lower end of the guide rod is connected to a lever B, which is drivenly connected to a lever A. Pressing down the guide rod causes the lever B to move the lever A.

[0015] Preferably, the lever A has a guide groove, and the lever B has a slide rod, which is slidably inserted into the guide groove so as to slide appropriately in the guide groove when the lever moves up and down.

[0016] Preferably, the upper end of the guide rod is connected to a pressure plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are: under the structure of this solution, when the pot leaves the support, the triggering mechanism loses the downward pressure of the pot. At this time, the rising triggering mechanism actuates the valve assembly to make the external gas pipe automatically close, and the outer flame ring on the burner head will automatically extinguish, thereby reducing the gas consumption when burning dry.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1-7The energy-saving gas stove shown includes a main body 1, on which at least one burner 2 is installed. It should be noted that the burner has an inner and outer dual-flame ring design. Correspondingly, the burner has an inner ring gas distribution pipe 21 connected to the inner flame ring and an outer ring gas distribution pipe 22 connected to the outer flame ring. Simultaneously, a valve assembly 3 is installed inside the main body. This valve assembly is connected to the inner ring gas distribution pipe 21 and the outer ring gas distribution pipe 22, and is also connected to an external gas source to control the gas intake during cooking via its own fine-tuning valve. It should be noted that the valve assembly in this design is a standard feature of gas stoves, and it also integrates an ignition system to enable the gas stove to ignite.

[0030] like Figure 1 As shown, a support 4 is also installed on the countertop of the main body 1 to place the pot above the stove head 2 during cooking.

[0031] To ensure the outer flame automatically extinguishes when the pot is removed from the support (for washing or serving), thus reducing gas waste, this design includes a self-regulating mechanism 5. This mechanism 5 comprises a valve assembly 51 connected to the outer duct and a trigger assembly 52 mounted on the support. The trigger assembly and valve assembly are connected and driven. When the pot is on the support, the trigger assembly is under pressure, driving the valve assembly to be fully open to ensure smooth flow of combustible gas in the outer gas distribution pipe 22. When the pot is removed from the support, the trigger assembly 52 loses pressure, retracts, and closes the valve assembly 51, thus automatically extinguishing the outer flame after the pot leaves the support.

[0032] Specifically, the valve assembly 51 includes a sleeve 511, which is open at both ends and connected in series in the outer gas distribution pipe 22. Simultaneously, an adjusting plate A512 is coaxially disposed within the sleeve, with several through holes A513 evenly distributed on the adjusting plate A512 to ensure that combustible gas can pass through the through holes A513. It should be noted that the adjusting plate A512 is fixedly connected to the inner wall of the sleeve via a connecting part. To achieve the closing of the valve assembly 51 when the pot is lifted, at least one adjusting plate B514 is also present in the sleeve 511, which also has several through holes B515. It should be noted that when the pot is placed on the support 4, the triggering component 51 controls the adjusting plate B to be in a state where the through holes B and A are coaxially connected. At this time, combustible gas can smoothly pass through the valve assembly 51 and enter the outer ring of the burner. When the pot is lifted, the trigger assembly resets the adjusting plate B514. At this point, through holes A and B are misaligned and block each other, thus closing the valve assembly 51. It's important to note that to facilitate the rotation of the adjusting plate B by the trigger assembly 52, a radially extending lever A516 is provided on the edge of the adjusting plate B, extending from the sleeve 511. This lever A can be rotated through an arc-shaped clearance groove on the side wall of the sleeve 511 and connects to the trigger assembly. Thus, the lever A can move up and down with the lifting and lowering of the trigger assembly, thereby causing the adjusting plate B to rotate relative to the adjusting plate A within the sleeve. This achieves either coaxial connection or misaligned closure between through holes A and B.

[0033] It should be noted that in this solution, the trigger component 52 specifically includes a guide rod 521 inserted into the bracket. Specifically, the bracket has at least one vertically penetrating channel connecting to the interior of the main body, and a guide rod capable of vertical movement within each channel is inserted. The lower end of the guide rod extends into the main body 1, while the upper end extends out of the bracket. Furthermore, a return spring 522 is connected to the upper end of the guide rod, ensuring that the guide rod pressed down by the pot always has a tendency to spring upwards and return to its original position. Additionally, a lever B 523 is connected to the lower end of the guide rod 521 extending into the main body. This lever B is driven by the lever A in the valve assembly, allowing the rising and falling guide rod to actuate lever A via lever B. It should be noted that in this solution, the preferred number of guide rods is four, meaning one is inserted into each leg of the bracket, and the lever B in this solution is a "[" structure connected to all four guide rods. Therefore, as long as the bottom of the pot is still pressed on at least one guide rod, the valve assembly can be kept in the open state, meaning that even if the pot is tossed during cooking, the outer ring of fire will not go out.

[0034] It should be noted that the drive connection between lever A and lever B can be of various types. The simplest and most reliable structure is one in which lever A 516 has a guide groove 517, and lever B 523 has a protruding slide rod 524 that slides into the guide groove 517. When the guide rod 521 moves up and down, the slide rod drives lever A to flip, while the slide rod 524 can also slide adaptively in the guide groove, avoiding obstruction to the flipping of lever A.

[0035] Furthermore, it should be noted that the contact area between the upper end of the guide rod 521 and the bottom of the pot is limited. Poor contact and subsequent misoperation are inevitable. Therefore, this solution incorporates the following preferred approach: Specifically, a pressure plate 53 is connected to the upper end of the guide rod 521. This pressure plate increases the contact area with the bottom of the pot, ensuring that the pot's rising and falling status is accurately reflected in the guide rod's movement, ultimately achieving precise control of the valve assembly's opening and closing.

[0036] Working Principle: When the pot is placed on the support, the guide rod is compressed, causing the return spring to descend. At this time, the lever B at the bottom of the guide rod drives the lever A to flip, so that the through hole B on the adjusting plate B and the through hole A on the adjusting plate A are aligned and connected. The valve assembly is fully open, allowing combustible gas to flow smoothly through the valve assembly into the outer ring of the burner head, providing fuel for the outer ring flame. When the pot is lifted, the guide rod rises under the elastic force of the return spring. At this time, the rising guide rod drives the lever A upward through lever B, causing the adjusting plate B to flip and the through holes B and A to misalign and close. The valve assembly then automatically closes, achieving automatic gas shut-off and extinguishing of the outer ring flame after the pot leaves the support. Through the above operation, the gas wasted by dry burning is reduced, ultimately achieving the goal of energy saving.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
