[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] In related technologies, the cooking device has a first chamber for cooking food and a second chamber for combustion. The cooking device also has an air inlet and an air outlet 23 that connect the first and second chambers. The air outlet 23 is positioned directly opposite the burner. When the oxygen-deficient gas in the first chamber flows into the second chamber from the air outlet 23, the oxygen-deficient gas will be directly blown toward the burner because the air outlet 23 is positioned directly opposite the burner, thereby affecting the flame combustion stability of the burner.

[0033] The following is for reference. Figures 1-4 A cooking apparatus according to an embodiment of the present invention is described.

[0034] The cooking apparatus 100 according to the present invention includes: a housing 11 and a burner 31, wherein a first cavity 101 and a second cavity 102 are formed in the housing 11; a support member 21 is disposed in the first cavity 101 and is used to support the food to be cooked; the burner 31 is disposed in the second cavity 102, the burner 31 is connected to a gas pipeline and the gas is suitable for combustion in the burner 31; wherein the housing 11 is provided with a partition plate 12 separating the first cavity 101 and the second cavity 102, and an air inlet 22 and an air outlet 23 are formed on the partition plate 12, the air outlet 23 is disposed above the burner 31, and the air inlet 22 is disposed on at least one side in the width direction of the air outlet 23.

[0035] In some specific embodiments, the cooking device 100 consists of a housing 11 and a burner 31. The housing 11 has a receiving space, and a partition plate 12 is disposed within the receiving space, dividing it into a first chamber 101 and a second chamber 102. The first chamber 101 is used to heat and cook the food. The second chamber 102 contains the burner 31, which is connected to a combustion pipe connected to an external gas source. The combustion pipe supplies gas to the burner 31, where the gas burns and forms high-temperature gas in the second chamber 102. The partition plate 12 also has an air inlet 22 and an air outlet 23 connecting the first chamber 101 and the second chamber 102. The high-temperature gas in the second chamber 102 can pass through the air inlet 22... The gas flows into the first chamber 101, thus heating the food to be cooked in the first chamber 101. The gas in the first chamber 101 can flow into the second chamber 102 through the air outlet 23, realizing airflow circulation between the first chamber 101 and the second chamber 102, avoiding airflow turbulence or local concentration, ensuring a more uniform airflow distribution in the first chamber 101, and improving the temperature uniformity in the first chamber 101. The air outlet 23 is located above the burner 31, so the oxygen-deficient gas flowing from the first chamber 101 into the second chamber 102 will not be blown directly onto the burner 31, effectively preventing the oxygen-deficient gas from interfering with the flame combustion of the burner 31, avoiding insufficient oxygen supply to the root of the burner 31 and causing insufficient flame rigidity, thus improving the combustion effect and combustion efficiency of the burner 31.

[0036] According to the present invention, the cooking apparatus 100 separates the first chamber 101 and the second chamber 102 by a partition plate 12. An air inlet 22 and an air outlet 23 are formed on the partition plate 12. Gas in the first chamber 101 can flow into the second chamber 102 through the air outlet 23, and high-temperature gas in the second chamber 102 can flow into the first chamber 101 through the air inlet 22. This realizes airflow circulation between the first chamber 101 and the second chamber 102, avoids airflow turbulence or local concentration, ensures a more uniform airflow distribution in the first chamber 101, and improves the temperature uniformity in the first chamber 101. The air outlet 23 is located above the burner 31, so that the oxygen-deficient gas flowing from the first chamber 101 into the second chamber 102 will not interfere with the flame combustion of the burner 31, thereby improving the flame stability of the burner 31.

[0037] According to some embodiments of the present invention, an air outlet area 24 is formed on the partition plate 12, and multiple air outlets 23 are provided in the air outlet area 24 to ensure that the airflow is more rationally distributed when flowing from the first cavity 101 into the second cavity 102, avoiding airflow turbulence or local concentration, and ensuring that the airflow distribution in the first cavity 101 is more uniform. The air outlet area 24 is located above the burner 31, which can ensure that there is sufficient oxygen supply around the burner 31, improve the combustion efficiency of the burner 31, reduce the emission of harmful gases from the burner 31, and improve the safety and reliability of the cooking device 100. In addition, by setting the air outlet area 24 above the burner 31, it can also prevent the oxygen-deficient gas in the first cavity 101 from blowing directly onto the burner 31, prevent the flame of the burner 31 from going out or becoming unstable due to lack of oxygen, and improve the flame combustion stability and safety of the burner 31.

[0038] According to some embodiments of the present invention, a combustion zone with a height of h is formed above the burner 31, and the height of the combustion zone is not less than 1 / 3 of the flame length H; the distance between the lower edge of the air outlet area 24 and the burner 31 is L1, and satisfies: L1≥h.

[0039] In some specific embodiments, the height h of the combustion zone refers to the distance from the edge of the flame outlet 32 ​​of the burner 31 to the highest point of the flame combustion emitted from the flame outlet 32. When L1 satisfies the above relationship (i.e., L1≥h), the oxygen-deficient gas flowing from the first chamber 101 into the second chamber 102 will not be directly blown towards the combustion zone, effectively preventing the oxygen-deficient gas from interfering with the flame combustion of the burner 31, avoiding insufficient oxygen supply at the root of the burner 31 and resulting in insufficient flame rigidity, thereby improving the combustion effect and combustion efficiency of the burner 31.

[0040] According to some embodiments of the present invention, the air outlet area 24 is constructed as a circle or a polygon, and the air outlet area 24 is disposed at the center of the partition plate 12. Distributing the air outlet area 24 at the center of the partition plate 12 ensures that the gas in the first cavity 101 enters the second cavity 102 through the air outlet area 24 in a concentrated manner. The circular or polygonal design of the air outlet area 24 ensures that the gas in the first cavity 101 enters the second cavity 102 evenly, avoiding excessively high local temperatures in the first cavity 101 and improving the cooking quality within the first cavity 101. The circular or polygonal design of the air outlet area 24 also ensures a more reasonable distribution of airflow within the cooking cavity, avoiding turbulent or locally concentrated airflow, ensuring a more uniform airflow distribution within the cooking cavity, and improving the temperature uniformity within the first cavity 101. According to some embodiments of the present invention, multiple air outlets 23 are spaced apart within the air outlet area 24, each air outlet 23 having a diameter R1 and satisfying: R1 < 5.5 mm.

[0041] In some specific embodiments, when R1 meets the above range (i.e., R1 < 5.5 mm), since the wavelength range of microwaves is usually around 12.2 cm, and the diameter of the air outlet 23 is less than 5.5 mm, the aperture of the air outlet 23 is smaller than the wavelength of microwaves. Therefore, it can effectively block the propagation of microwaves and prevent microwave leakage, ensuring that microwave energy is concentrated in the first cavity 101. This improves the safety and reliability of the cooking device 100 while also increasing the cooking efficiency of the cooking device 100.

[0042] According to some embodiments of the present invention, the area of ​​the air inlet 22 is S1, and the area of ​​the air outlet 23 is S2, and the following condition is met: S1 / S2≥1 / 4.

[0043] When S1 / S2 satisfies the above relationship, the larger area of ​​the air outlet 23 relative to the smaller area of ​​the air inlet 22 allows the high-temperature airflow flowing into the first cavity 101 to be fully mixed with the low-temperature airflow in the first cavity 101. The airflow distribution in the first cavity 101 is more uniform and the temperature at each position in the first cavity 101 is more uniform, thereby improving the cooking effect of the cooking device 100.

[0044] According to some embodiments of the present invention, the cooking device 100 further includes a support member 21, which is disposed in the first cavity 101 and is used to support the food to be cooked, and is disposed on the lower side of the air inlet 22.

[0045] In some specific embodiments, a support member 21 is also provided in the first cavity 101. The support member 21 can be used to hold the food to be cooked. Since the support member 21 is located below the air inlet 22, the high-temperature gas flowing in from the air inlet 22 can be mixed with the cold air in the first cavity 101 before being blown towards the food to be cooked. The high-temperature gas flowing in from the air inlet 22 will not be blown directly towards the food to be cooked, thus avoiding the high-temperature gas from being blown directly towards the food to be cooked, which could cause local overheating or burning of the food to be cooked, and ensuring the uniformity of the surface temperature of the food to be cooked.

[0046] According to some embodiments of the present invention, the carrier 21 is constructed as multiple trays, which allow users to cook multiple foods at the same time. Each tray can hold different types of food, which improves the cooking efficiency of the cooking device 100. The multiple trays are spaced apart in the height direction of the first cavity 101, and each tray is located below the air inlet 22. This can effectively prevent the upper tray from blocking the airflow of the lower tray, ensuring that the food to be cooked on each tray can fully contact the airflow blown in by the air inlet 22, and ensuring that the food to be cooked on each tray can be heated evenly.

[0047] According to some embodiments of the present invention, the partition plate 12 is provided with air inlets 22 corresponding to multiple trays one by one, so as to ensure that the high-temperature gas flowing into each air inlet 22 can directly heat the food to be cooked on the tray in the corresponding area, thereby improving the cooking efficiency of the cooking device 100. Each air inlet 22 is located above the tray and the distance between the lower edge of the air inlet 22 and the tray is L2, where L2 ≥ 20 mm. When L2 is within the above range, it can provide sufficient buffer mixing space for the high-temperature gas entering the first cavity 101 through the air inlet 22. After entering the first cavity 101, the high-temperature gas first mixes with the low-temperature gas above the tray to form a relatively gentle airflow before being blown toward the food to be cooked, thus avoiding the high-temperature gas being blown directly toward the food to be cooked, which would cause local overheating of the food to be cooked and improving the heating uniformity of the food to be cooked.

[0048] According to some embodiments of the present invention, the cooking device 100 further includes a fan wheel 33, which is rotatably disposed on the housing 11 and is used to drive the airflow in the first chamber 101 toward the second chamber 102.

[0049] In some specific embodiments, a fan wheel 33 is also provided inside the housing 11. The fan wheel 33 can rotate inside the housing 11. The fan wheel 33 drives the airflow from the first chamber 101 to the second chamber 102, which promotes the circulation of high-temperature gas between the first chamber 101 and the second chamber 102, ensures the constant temperature in the first chamber 101, improves cooking efficiency and the uniformity of heating of the food to be cooked, and the fan-driven gas flow can provide oxygen to the burner 31, ensuring a more complete and stable combustion process and improving the combustion efficiency of the burner 31.

[0050] According to some embodiments of the present invention, the housing 11 further forms a third cavity 103 communicating with the second cavity 102. The third cavity 103 is connected to the first cavity 101 through the air inlet 22. The impeller 33 is rotatably disposed in the third cavity 103. The impeller 33 rotates in the third cavity 103 to drive the high-temperature gas in the second cavity 102 and the low-temperature gas flowing into the second cavity 102 from the first cavity 101 to flow toward the third cavity 103 and mix thoroughly in the third cavity 103. The mixed low-temperature gas and high-temperature gas flow back to the first cavity 101 through the air inlet 22 and heat the food to be cooked in the first cavity 101, ensuring the temperature consistency of each part of the food to be cooked and improving the cooking effect. The air outlet 23 is at least partially facing each other. The facing arrangement of the impeller and the air outlet 23 can more directly guide the airflow, ensuring that the airflow in the first cavity 101 flows into the second cavity 102 stably and efficiently from the air outlet 23, improving the gas flow efficiency between the first cavity 101 and the second cavity 102.

[0051] According to some embodiments of the present invention, the housing 11 further forms a fourth cavity 104, in which a motor 35 is disposed. Separating the motor 35 into the fourth cavity 104 can protect the motor 35 from the exhaust gas during the cooking process, and at the same time isolate the motor 35 from the high-temperature third cavity 103 and second cavity 102, reducing the risk of overheating of the motor 35 and extending the service life of the motor 35. The output shaft of the motor 35 is connected to the impeller 33 to drive the impeller 33 to rotate. The motor 35 can output stable power to the impeller 33 to ensure the stable rotation speed of the impeller 33, thereby providing uniform and continuous airflow.

[0052] According to some embodiments of the present invention, the top of the housing 11 is formed with a flue 105 communicating with the first cavity 101, and the flue 105 is communicating with the fourth cavity 104.

[0053] In some specific embodiments, the top of the housing 11 is provided with a smoke exhaust channel, which is connected to the first chamber 101 and the fourth chamber 104 respectively. The high-temperature gas generated by the burner 31 in the second chamber 102 is drawn into the third chamber 103 through the air inlet 33. The high-temperature gas in the third chamber 103 flows into the first chamber 101 through the air inlet 22 and heats the food to be cooked in the first chamber 101. When the food to be cooked is heated, some cooking smoke and exhaust gas will be generated in the first chamber 101. The cooking smoke and exhaust gas can be discharged to the external environment through the smoke exhaust duct 105 to ensure that the smoke and exhaust gas generated by the cooking device 100 during the cooking process can be discharged quickly, maintain the cleanliness of the environment in the first chamber 101, reduce the accumulation of oil fumes in the first chamber 101, and improve the hygiene and taste of the food to be cooked.

[0054] When the motor 35 drives the fan wheel 33 to rotate, it generates a certain amount of heat. The motor 35 is equipped with heat dissipation blades on its exterior. The rotation of the heat dissipation blades generates airflow, which carries the heat generated on the motor 35 toward the exhaust duct 105. The heat generated by the motor 35 can flow to the external environment through the exhaust duct 105, thereby ensuring that the heat on the motor 35 can be effectively dissipated. The temperature inside the fourth chamber 104 will not be too high, ensuring that the temperature environment of the motor 35 is at the normal operating temperature of the motor 35, improving the stability and reliability of the motor 35 during operation, and extending the service life of the motor 35.

[0055] According to some embodiments of the present invention, the cooking device 100 further includes a microwave unit disposed in the housing 11. The microwave unit can heat food by emitting electromagnetic waves (i.e. microwaves). When microwaves enter the first cavity 101 and come into contact with the food to be cooked, polar molecules such as water molecules, fats and sugars in the food to be cooked will absorb microwave energy, causing the polar molecules such as water molecules, fats and sugars in the food to be cooked to vibrate rapidly under the action of microwaves and generate heat, thereby realizing rapid heating of the food to be cooked from the inside out, improving the heating speed and heating effect of the food to be cooked.
