Description

Technical Field

[0001] This invention belongs to the field of gas stove technology, specifically relating to a new type of healthy, environmentally friendly and energy-saving stove. Background Technology

[0002] A gas stove is a kitchen appliance that uses gaseous fuels for direct-fire heating, primarily liquefied petroleum gas, manufactured gas, and natural gas. Gas enters the stove through the inlet pipe, is regulated by the gas valve, and then enters the burner head, mixing with a portion of primary air. This mixture is ejected from the burner's flame holes and ignited by the ignition device to form a flame. The secondary air required for combustion is obtained from the surrounding environment, and the flame is used to heat the cookware placed on the pot support.

[0003] Existing gas stoves have the burner cap assembly located at the top of the stove, without forming a combustion chamber, resulting in insufficient utilization of the heat generated by natural gas combustion. Furthermore, the resulting fumes easily drift into the air and are inhaled by cooks, posing health and environmental risks.

[0004] Therefore, it is necessary to design a new type of healthy, environmentally friendly, and energy-saving stove. Summary of the Invention

[0005] To address the aforementioned problems in existing technologies, this solution provides a new type of healthy, environmentally friendly, and energy-saving stove.

[0006] The technical solution adopted in this invention is as follows: A new type of healthy, environmentally friendly, and energy-saving stove, comprising: Stove exterior; An inner gas collection hood is embedded in the top surface of the stove shell; the center of the inner gas collection hood has a concave fire chamber for placing cookware; the top of the inner gas collection hood is equipped with a smoke extraction hole and the bottom is equipped with an internal fresh air hole. An external air collection hood is located below the internal air collection hood; an external fresh air inlet is located in the middle of the external air collection hood; part of the fresh air passing through the external fresh air inlet flows to the internal fresh air inlet and the other part flows to the smoke inlet. The burner head assembly is installed at the bottom of the inner and outer gas collection hoods and is used for the combustion of natural gas.

[0007] Optional: The stove shell is connected to a smoke exhaust pipe, and an air channel is formed between the outer and inner gas collection hoods, with the smoke exhaust pipe connected to the air channel.

Detailed Implementation

[0018] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0019] Example like Figures 1 to 3 As shown, this embodiment designs a new type of healthy, environmentally friendly and energy-saving stove, including components such as a natural gas pipe 1, a control valve 2, a stove shell 3, an inner gas collection hood 4, a smoke exhaust pipe 5, a burner head cover assembly 6, an outer gas collection hood 7, an annular flue 8 and a smoke baffle 10.

[0020] The outer shell of the stove is a square shell structure.

[0021] The inner gas collection hood 4 is embedded in the top surface of the stove outer shell 3; the center of the inner gas collection hood 4 has a concave combustion chamber for placing cookware; the top of the inner gas collection hood 4 is provided with a smoke extraction hole 9 and the bottom is provided with an internal fresh air hole 12. The inner gas collection hood 4 has a concave basin-shaped structure, and the center of the inner gas collection hood 4 has a concave combustion chamber that can guide the flue gas after the natural gas combustion, so that the flue gas collides back and forth between the cookware and the inner gas collection hood 4, increasing the utilization rate of heat and improving heating efficiency.

[0022] The outer air hood 7 is located below the inner air hood 4; an outer fresh air inlet 11 is provided in the middle of the outer air hood 7; part of the fresh air passing through the outer fresh air inlet 11 flows to the inner fresh air inlet 12, and the other part flows to the smoke inlet 9. The outer air hood 7 has a concave basin-shaped structure.

[0023] The burner head cover assembly 6 is installed at the bottom of the inner gas collection hood 4 and the outer gas collection hood 7, and is used for the combustion of natural gas.

[0024] The stove outer shell 3 is connected to a smoke exhaust pipe 5, and an air channel is formed between the outer gas collection hood 7 and the inner gas collection hood 4. The smoke exhaust pipe 5 is connected to the air channel.

[0025] An annular flue 8 is provided on the outer periphery of the upper edge of the external gas collection hood 7, and the air passage is connected to the annular flue 8.

[0026] The outer shell 3 of the stove is provided with two stove positions, one on the left and one on the right; each stove position is equipped with an inner gas collection hood 4, an outer gas collection hood 7 and a burner head cover assembly 6.

[0027] The lower end of the exhaust pipe 5 is vertically connected between the two stove positions.

[0028] A smoke baffle 10 is provided between the two external gas collection hoods 7. The space between the smoke baffle 10 and the top wall of the stove shell 3 connects the annular flue 8 and the exhaust pipe 5.

[0029] A control valve 2 is provided on the front side of the stove shell 3, and a natural gas pipe 1 is provided on the left or right side of the stove shell. The natural gas pipe 1 is connected to the burner head cover assembly 6 through the control valve 2.

[0031] When using the structure of this embodiment: The upper end of the exhaust pipe 5 is connected to the suction fan to facilitate unified smoke exhaust and create negative pressure within the exhaust pipe 5. When the control valve 2 is opened and the burner cap assembly 6 is ignited, the flue gas generated by the combustion of natural gas can flow upwards along the gap between the inner gas collection hood 4 and the cookware to the smoke extraction port 9. Simultaneously, air below the stove outer shell 3 can enter between the inner gas collection hood 4 and the outer gas collection hood 7 through the outer fresh air vent 11 and flow along the air passage. Part of the air flows to the inner fresh air vent 12 to provide air for the combustion of natural gas at the burner cap assembly 6, while the other part flows to the smoke extraction port 9 and mixes with the flue gas through the space between the annular flue 8, the smoke baffle 10, and the top wall of the stove outer shell 3, entering the exhaust pipe 5, which then sends the flue gas to a unified air purification device for purification. The air passage between the inner gas collection hood 4 and the outer gas collection hood 7 can isolate heat, thereby reducing the impact of the temperature generated by the burner on the countertop on which the stove outer shell 3 is installed.

[0032] In this design, the smoke extraction port 9 on the upper part of the smoke collection hood 4 allows fumes to be drawn into the exhaust pipe 5, thereby reducing the risk of fumes entering the air and being inhaled by the cook and improving health protection. The exhaust pipe 5 then transports the fumes to an air purification device for unified purification, further enhancing environmental friendliness.

[0033] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
