Description

Technical Field

[0001] The present invention relates to a cooking appliance, and particularly to a cooking appliance provided with an energy-saving component. Background Art

[0002] Currently, there are certain defects in the mixing of gas and air and the combustion efficiency of cooking appliances on the market. Traditional cooking appliances usually lack an efficient pre-mixing mechanism, making it difficult for gas and air to be fully and evenly mixed. As a result, during combustion, some gas cannot come into contact with sufficient oxygen, leading to incomplete combustion. This not only causes waste of energy and increases the usage cost, but also may produce harmful gases such as carbon monoxide, posing a threat to the environment and the health of users.

[0003] In terms of the mixing structure design, the designs of most existing cooking appliances are relatively simple. They may simply introduce gas and air directly into the combustion area without optimizing the mixing process, unable to achieve efficient mixing of gas and air, thus affecting the combustion effect and making it difficult to improve the energy utilization efficiency. These problems make traditional cooking appliances perform poorly in terms of energy conservation and environmental protection and urgently need improvement.

[0004] Therefore, existing cooking appliances need to be further improved. Summary of the Invention

[0013] When the movable plate moves forward and backward, the transmission gear is driven to move along the setting direction of the rack and the transmission gear is driven to rotate.

[0014] Furthermore, the air delivery structure includes a central axis hole arranged at the axis of the central transfer shaft, an air input pipe is arranged on the pressure plate guide groove on one side of the central guide rod, and a side opening for being sleeved on the outer wall of the air input pipe is arranged on one side of the movable plate, and a plurality of the air input pipes are connected to the central axis hole.

Arc-shaped blocking channel, the arc-shaped blocking channel at the outer end of one side of the concave structure, whose arc-shaped blocking plate can effectively block the air that is not fully mixed in the left chamber from directly discharging to the mixed gas output end pipe, ensuring that the gas entering the cooker body for combustion is fully mixed gas, improving the stability and efficiency of combustion. At the same time, combining multiple arc-shaped blocking channels can increase the circumferential area connected to the mixed gas output end pipe, ensuring continuous output of mixed gas from the mixed gas output end pipe; Through the synergistic effect of the above various structures, this cooker realizes the efficient mixing of gas and air and full combustion, thereby significantly improving the energy utilization efficiency and achieving the purpose of energy conservation. At the same time, full combustion reduces the generation of harmful gases, is more environmentally friendly, and meets the requirements of modern society for energy-saving and environmentally friendly products.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-8 , the present invention provides a cooking stove provided with an energy-saving component, including a cooking stove body 1 and a blower component 2 arranged in the cooking stove body 1, and is characterized in that: a pre-mixing valve body 3 is arranged in the cooking stove body 1, a gas inlet pipe 4 is arranged on one side of the pre-mixing valve body 3, and a mixed gas outlet pipe 5 is arranged on the other side. An inner concave structure 8 capable of dividing the pre-mixing valve body 3 into a plurality of mixing chambers 7 is arranged on the rotating component 6. An elastic pressing plate component 9 for increasing the pressure of the mixing chamber 7 is arranged in the mixing chamber 7. A stirring component 10 is arranged on the elastic pressing plate component 9. A reciprocating self-rotation linkage component 11 for driving the stirring component 10 to rotate reciprocally is arranged between the stirring component 10 and the inner concave structure 8. An air conveying structure 12 for conveying air to a plurality of the mixing chambers 7 is arranged on the rotating component 6. An arc-shaped blocking channel 13 is arranged at the outer end of one side of the inner concave structure 8;

[0032] An angle closing structure 14 is arranged between the pre-mixing valve body 3 and the air conveying structure 12. When one of the mixing chambers 7 is communicated with the mixed gas outlet pipe 5, the corresponding mixing chamber 7 is closed by the angle closing structure 14 to stop the input of air;

[0033] Rotating assembly (6): The drive motor (602) is installed on the motor base (601). After starting, the driving gear (603) at its output end rotates. The driving gear (603) meshes with the driven gear (607) on the circumferential outer wall of the middle rotating shaft (606) to drive the middle rotating shaft (606) and the rotating member (605) fixedly connected thereto to rotate in the hybrid circular groove (604). The rotation of the rotating member (605) enables each hybrid chamber (7) to participate in the mixing and gas output processes in sequence.

[0034] Air delivery and mixing process;

[0035] Rotary joint connection: A rotary joint is installed at one end of the middle rotating shaft 606. One end of the rotary joint is communicated with the middle shaft hole 121, and the other end is connected to the external blower pipeline. It can adapt to the continuous rotation of the middle rotating shaft 606 while ensuring the smooth delivery of air. It usually has a sealing structure inside to effectively prevent air leakage, ensure stable gas transmission, and maintain the normal working pressure of the cooking appliance.

[0036] Air delivery: Air enters through the air blowing assembly (2), passes through the middle shaft hole (121) at the axis of the middle rotating shaft (606), and is then delivered to the left chamber (100) of each hybrid chamber (7) through a plurality of air input pipes (122) communicated with the middle shaft hole (121). The side opening (123) on one side of the movable plate member (902) is sleeved on the outer wall of the air input pipe (122) to ensure the smooth entry of air.

[0037] Gas input: The rotating member (605) rotates continuously clockwise. First, gas enters the right chamber (200) of each hybrid chamber (7), enters the pre-mixing valve body (3) through the gas inlet pipe (4), and meets the air entering the left chamber (100).

[0038] When one of the said hybrid chambers (7) continuously enters gas, at this time the elastic pressing plate assembly (9) starts to compress, and increases the pressure inside the hybrid chamber (7), increasing the contact between gas molecules;

[0039] When the hybrid chamber (7) is aligned with the position of the mixed gas output end pipe (5), at this time the corresponding hybrid chamber (7) pushes the mixed gas outwards through the reset of the elastic pressing plate assembly (9);

[0040] The movable plate member (902) of the elastic pressing plate assembly (9) is sleeved on the middle guide rod (904) through the middle guide hole (903). The spring structure (905) on the middle guide rod (904) presses the movable plate member (902) outwards, increasing the pressure inside the hybrid chamber (7), which helps to improve the mixing effect of gas and air, and also promotes the flow of the mixed gas towards the arc-shaped gas transmission channel (132).

[0041] Gas output and angle closure

[0042] Mixing process: During the continuous compression and reset actions of the elastic pressing plate assembly (9), the disk turbine stirring paddle (102) will perform reciprocating motion. When the movable plate member (902) moves back and forth, the transmission gear (113) at the upper end of the disk turbine stirring paddle (102) on the outer end stirring blade mounting seat (101) will move along the rack (112) on the side wall of the radial slot (111) on the upper surface of the arc-shaped groove (801) and rotate itself, thereby stirring and mixing the gas and air in the left chamber (100). The mixed gas enters the right chamber (200) through the disk turbine stirring paddle (102).

[0043] Gas output by the elastic pressing plate assembly (9): The mixed gas is discharged from the right chamber (200) into the arc-shaped gas transmission channel (132) on the arc-shaped partition plate (131). When the rotating member (605) rotates to a position where a certain arc-shaped gas transmission channel (132) communicates with the mixed gas output end pipe (5), the mixed gas is sent to the stove body (1) for combustion by the pressure of the elastic pressing plate assembly (9) resetting the mixed gas output end pipe (5).

[0044] Angle closure: The angle closure structure (14) is an arc-shaped closure plate member fixed at the central position of the mixed circular groove (604) and installed in the central shaft hole (121). When a certain mixing chamber (7) communicates with the mixed gas output end pipe (5), the arc-shaped closure plate member will block the corresponding air input pipe (122), stop the air input of this mixing chamber (7), avoid unnecessary air entry, and achieve precise control.

[0045] Through the coordinated work of each component, this stove realizes the efficient mixing of gas and air, precise control of air input, and stable gas output, improves the combustion efficiency and energy utilization rate, and achieves the purpose of energy conservation.
