Therefore, they cannot be understood as limiting the present invention.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] See also Figure 1-Figure 8 The present invention discloses a double-layer cooking vessel, comprising a cooking body 10, a first heating component and a second heating component. The cooking body 10 is provided with a first cooking cavity 13, a second cooking cavity 14 and an air duct, and the first cooking cavity 13 and the second cooking cavity 14 are distributed in the height direction of the cooking body 10. The first cooking cavity 13 is provided with a first opening, the end wall of the first cooking cavity 13 is provided with a first air guide port 131, and the side wall of the first cooking cavity 13 is provided with a second air guide port 132; the second cooking cavity 14 is provided with a second opening, the first opening can be used as an entrance and exit for putting food into the first cooking cavity 13, and the second opening can also be used as an entrance and exit for putting food into the second cooking cavity 14.

[0037] In addition, an air duct is provided in the cooking machine body 10, and the air duct is arranged around the outer peripheral wall of the first cooking cavity 13. The air duct has a first air guide section 151 and a second air guide section 152. The first air guide section 151 is arranged opposite to the first air guide port 131. The first air guide section 151 can guide the airflow into the first cooking cavity 13 through the first air guide port 131 of the first cooking cavity 13. The second air guide section 152 is connected and connected with the first air guide section 151, and the second air guide section 152 extends to the side of the first cooking cavity 13, and is used to guide the airflow to be introduced through the second air guide port 132.

[0038] The first heating assembly is mounted on the first air guide section 151 , and includes a first fan blade 41 and a first heating element 42 . The first fan blade 41 guides the heat of the first heating element 42 to flow in the air duct during rotation. The second heating assembly can heat the second cooking cavity 14 .

[0039] On the basis of the above structure, when cooking ingredients, since the cooking machine body 10 is provided with a first cooking cavity 13 and a second cooking cavity 14 distributed in the height direction, the two layers operate independently, and the double cavity structure is arranged in the height direction, it is only necessary to increase the height of the cooking machine body 10 without increasing the width of the cooking machine body 10, and the lateral space required for placement is smaller.

[0040] A first heating component is provided in the first cooking cavity 13 to heat the first cooking cavity 13, and a second heating component is provided in the second cooking cavity 14 to heat the second cooking cavity 14, so that the first cooking cavity 13 and the second cooking cavity 14 can be heated separately, and the ingredients can be heated and cooked independently at the same time, and cooking work can also be performed at the same time.

[0041] In addition, different cooking ingredients can be placed in the first cooking cavity 13 and the second cooking cavity 14 to cook different ingredients at the same time, and the first heating component and the second heating component are heated separately, thereby providing different cooking temperatures for different cooking ingredients, and the cooking time can also be different, while also avoiding the contamination of flavors.

[0042] It should also be noted that the first heating assembly includes a first heating element 42 and a first fan blade 41, and the first fan blade 41 can guide the heat generated by the first heating element 42 to flow in the first air guide section 151 when rotating. The heat in the first air guide section 151 is directly blown into the first cooking cavity 13 through the first air guide port 131 under the action of the first fan blade 41. The second air guide section 152 is connected with the first air guide section 151, and the heat can also flow to the second air guide section 152 through the first air guide section 151 under the action of the first fan blade 41, and flow into the first cooking cavity 13 through the second air guide port 132. In this way, the heat can be introduced into the first cooking cavity 13 through the end and side of the first cooking cavity 13, and the heat is more evenly delivered to the first cooking cavity 13, and the heat is introduced from multiple sides, so that the cooking ingredients in the first cooking cavity 13 are evenly heated, and the heating efficiency is high.

[0043] Further, see Figure 6 In this embodiment, the second air guide sections 152 are arranged on both sides of the first air guide section 151, and the second air guide ports 132 are arranged on both side walls of the first cooking cavity 13; the second air guide sections 152 on both sides extend to both sides of the first cooking cavity 13 and are respectively connected to the two second air guide ports 132. In this way, the first air guide section 151 is arranged opposite to the first opening of the first cooking cavity 13, so the air duct is divided into the first air guide section 151 at the end of the first cooking cavity 13 and the second air guide sections 152 extending to both sides of the first cooking cavity 13, forming a three-sided surrounding distribution mode. When the first heating element 42 is heated, the first fan blade 41 rotates to blow the heat directly into the first air guide port 131 through the heat in the first air guide section 151, and the heat in the first air guide section 151 flows through the second air guide sections 152 on both sides, and then is guided into the second cooking cavity 14 through the second air guide ports 132 on both sides of the second cooking cavity 14, so that the heat is transported on three sides, with high heating efficiency and uniform heating. At the same time, heat is introduced into the first cooking cavity 13 from the air ducts surrounding three sides. The heat is introduced on the same plane, the heating distance of the cooking ingredients is relatively consistent, and the cooking ingredients are heated relatively evenly, which makes it less likely to have inconsistent cooking effects.

[0044] The first heating component is distributed in the first air guiding section 151 and is on the same distribution plane as the two second air guiding sections 152. Therefore, the provision of the first heating component does not increase the overall height of the cooking machine body 10, but only requires an increase in thickness.

[0045] Further, see Figure 5The inner wall of the second air guiding section 152 is provided with an upper air guiding wall 1521 and a lower air guiding wall 1522. Both the upper air guiding wall 1521 and the lower air guiding wall 1522 are inclined. The upper air guiding wall 1521 is gradually inclined outward from top to bottom, and the lower air guiding wall 1522 is gradually inclined outward from bottom to top. The connecting position of the upper air guiding wall 1521 and the lower air guiding wall 1522 is formed into a recessed position, and the recessed position is directly opposite to the second air guiding port 132. In this way, after the heat in the first air guiding section 151 flows to the second air guiding section 152, the second heat conducting section can guide the heat downward at the upper air guiding wall 1521 inclined upward, and can guide the heat upward at the lower air guiding wall 1522 inclined downward. In this way, the heat entering the second introduction section is concentrated at the recessed position, and is concentratedly guided to the second air guiding port 132 through the recessed position, so as to realize the convergence and introduction of heat, reduce the loss of heat, improve the heat utilization rate, and achieve higher heating efficiency.

[0046] More specifically, a guide wall 1523 is provided at the end of the second air guide section 152 away from the first air guide section 151. The guide wall 1523 gradually tilts outward from the end away from the first air guide section 151 to the end close to the first air guide section 151 and connects to the recessed position. When heat flows to the second air guide section 152 through the first air guide section 151, the airflow flows toward the guide wall 1523. Since the guide wall 1523 is away from the first air guide section 151, that is, close to the first opening, in order to reduce heat loss toward the first opening, when heat flows to the guide wall 1523, the heat can be guided back to the recessed position, thereby reducing heat loss and improving heat utilization.

[0047] In addition, since the guide wall 1523 is close to the first opening, if the heat at the first opening is lost, it will cause burns when putting in or taking out cooking ingredients. Therefore, the guide wall 1523 guides the heat back to the recessed position, which can also reduce burns caused by the high temperature of the first opening.

[0048] Furthermore, a first frying basket 20 is detachably provided in the first cooking cavity 13, and the first frying basket 20 can be taken out or put into the first cooking cavity 13 through the first opening. When cooking food, the food is put into the first frying basket 20, and then the first frying basket 20 is put in through the first opening, and then the first heating component heats and cooks the food in the first cooking cavity 13. After the cooking action is completed, the first frying basket 20 is taken out through the first cooking cavity 13, which is convenient for taking and putting the cooking food.

[0049] Specifically, a plurality of air guide holes 22 are provided on both sides of the first frying basket 20, and the plurality of air guide holes 22 are provided corresponding to the second air guide port 132. In this way, the heat guided by the second air guide section 152 is guided into the cooking cavity through the second air guide port 132, and then introduced into the first frying basket 20 through the plurality of air guide holes 22, so that the heat can enter the first frying basket 20 conveniently and flow in the first frying basket 20, thereby achieving a better heating effect.

[0050] Of course, an end inlet hole 21 can also be set at the end of the first frying basket 20. After the first frying basket 20 is placed in the first cooking cavity 13, the end inlet hole 21 of the first frying basket 20 is set corresponding to the first air guide port 131, and the multiple air guide holes 22 on both sides of the first frying basket 20 correspond to the second air guide ports 132 on both sides of the first cooking cavity 13, respectively. In this way, the heat input from three sides can be introduced through the end inlet hole 21 and the air guide holes 22 on both sides, so that the food in the first frying basket 20 is heated on three sides, and the heating effect is uniform.

[0051] On the basis of the structure that the first frying basket 20 is not provided with the end inlet hole 21 and the air guide hole 22, the first frying basket 20 can also be made of a heat-conductive metal material, and heat can be guided by the heat-conductive material to achieve heat transfer.

[0052] Furthermore, since the first heating element 42 and the first fan blade 41 are both installed in the first air guide section 151, heat is generated by the first air guide section 151, and the end of the second air guide section 152 close to the first air guide section 151 is the inlet end, so that the heat introduced into the second air guide section 152 has a higher wind speed and a higher temperature at the inlet end, and a lower wind speed and a lower temperature at a position away from the inlet end. The second air guide section 152 is prone to temperature differences in the heat flow path through the multiple air guide holes 22 corresponding to the second air guide port 132. Therefore, in the present embodiment, the aperture of the air guide hole 22 near the first air guide section 151 on the first frying basket 20 is set to be smaller than the aperture of the air guide hole 22 far away from the first air guide section 151, that is, the aperture of the air guide hole 22 near the inlet end of the second air guide section 152 is smaller, and the introduced wind speed and air volume are relatively small, while the aperture of the air guide hole 22 far away from the inlet end of the second air guide section 152 is larger, and the introduced wind speed and air volume are relative to the angle. Based on the actual air guiding conditions of the first air guide section 151, the temperature difference of the air flow introduced by different air guide holes 22 in the heat flow direction is smaller, and the food in the first frying basket 20 is heated more evenly.

[0053] Further, see Figure 3 , Figure 4 as well as Figure 5 The cooking machine body 10 is provided with a first outlet 11; the first air guide section 151 is provided with a first heat insulation cover 60, and first openings 63 are provided on both sides of the first heat insulation cover 60, and the first openings 63 on both sides are respectively connected to the two second air guide sections 152.

[0054] In addition, a second opening 61 and an exhaust channel 62 are provided at the top of the first heat insulation cover 60; the second opening 61 is connected to one end of the exhaust channel 62, and the other end of the exhaust channel 62 passes through the first exhaust port 11; the first heating element 42 and the first fan blade 41 are both arranged on the inner side of the first heat insulation cover 60; the outer side of the first heat insulation cover 60 and the inner wall of the first air guide section 151 are separated into an installation cavity, and a first motor 43 is provided in the installation cavity, and a rotating shaft of the first motor 43 extends into the first heat insulation cover 60 and is connected to the first fan blade 41.

[0055] Based on this structure, when the first heating assembly heats the first cooking cavity 13, the first heating element 42 and the first fan blade 41 are installed on the inner side of the cooking body 10 with the first heat insulation cover 60, and the first heat insulation cover 60 can block the heat generated by the first heating element 42 from flowing toward the surface of the cooking body 10, thereby preventing the surface of the cooking body 10 from overheating. At the same time, the first motor 43 is arranged outside the first heat insulation cover 60, so the first heat insulation cover 60 can also reduce the influence of the heat in the first cooking cavity 13 on the first motor 43, thereby reducing the situation where the first motor 43 is overheated.

[0056] The rotating shaft of the first motor 43 can drive the first blade 41 to rotate. The rotation of the first blade 41 can guide the heat generated by the first heating element 42 to flow in the first heat insulation cover 60. Part of the heat in the first heat insulation cover 60 is directly guided to the first cooking cavity 13 through the first air guide port 131, and part of the heat of the first heat insulation cover 60 can also be introduced into the second air guide sections 152 on both sides through the first through ports 63 on both sides. The first heat insulation cover 60 concentrates the heat to improve the heat utilization rate. In addition, the first through ports 63 on both sides guide the heat to achieve three-sided surrounding transmission, uniform heating, and high heating efficiency.

[0057] When the heat is used to heat the first cooking cavity 13, steam, grease, etc. will be generated in the first cooking cavity 13 due to cooking. The steam, grease, etc. will be guided to the discharge channel 62 through the second opening 61 at the top of the first heat insulation cover 60, and then discharged to the first discharge port 11 of the cooking body 10 through the discharge channel 62, thereby realizing independent dehumidification of the first cooking cavity 13, preventing odor transfer, and not affecting the cooking of ingredients in the second cooking cavity 14.

[0058] Furthermore, the second heating component is disposed at the top of the second cooking cavity 14, and the second heating component includes a second fan blade 51 and a second heating element 52. The second heating element 52 is disposed at the top of the second cooking cavity 14, and the second fan blade 51 is used to guide the heat of the second heating element 52 to flow in the second cooking cavity 14 when rotating.

[0059] In this way, the second heating component is arranged at the top of the second cooking cavity 14, and the heat generated by the second heating element 52 is driven to flow from top to bottom by the rotation of the second fan blade 51, so that the flowing heat can be used to fry and cook the food in the second cooking cavity 14. That is, the second cooking cavity 14 can realize the function of an air fryer.

[0060] Of course, in this embodiment, the second cooking cavity 14 is arranged above the first cooking cavity 13, so as to facilitate the arrangement of the second heating assembly at the top of the second cooking cavity 14. The first cooking cavity 13 below is provided with a three-sided surrounding air duct structure, and the arrangement structure distribution of the entire cooking machine body 10 is reasonable.

[0061] Furthermore, a second discharge port 12 is provided on the cooking machine body 10, a second heat insulation cover 70 is provided at the top of the second cooking cavity 14, a third opening 71 is provided on the side of the second heat insulation cover 70, and the third opening 71 is correspondingly connected to the second discharge port 12; the second fan blades 51 and the second heating element 52 are both arranged on the inner side of the second heat insulation cover 70; a second motor 53 is provided on the outside of the second heat insulation cover 70, and a rotating shaft of the second motor 53 extends into the second heat insulation cover 70 and is connected to the second fan blades 51.

[0062] When cooking the food in the second cooking cavity 14, the second motor 53 drives the second blade 51 to rotate, and the rotation of the second blade 51 can guide the heat of the second heating element 52 inside the second heat insulation cover 70 to flow downward, reduce heat overflow, and improve heat utilization. At the same time, the second motor 53 is arranged outside the second heat insulation cover 70 to reduce the damage of the second motor 53 due to the heat of the second cooking cavity 14.

[0063] In addition, steam, grease, etc. will be generated in the second cooking cavity 14 due to cooking, so a third opening 71 is provided on the side of the second heat insulation cover 70. The steam, grease, etc. will be guided to the second exhaust port 12 through the third opening 71 at the top of the second heat insulation cover 70, thereby realizing independent dehumidification of the second cooking cavity 14, preventing odor contamination, and not affecting the cooking of ingredients in the first cooking cavity 13.

[0064] Furthermore, a second frying basket 30 is detachably provided in the second cooking cavity 14. The second frying basket 30 can be taken out or put into the second cooking cavity 14 through the second opening. When cooking food, the food is put into the second frying basket 30, and then the second frying basket 30 is put into the second opening. Thereafter, the second heating component heats and cooks the food in the second cooking cavity 14. After the cooking action is completed, the second frying basket 30 is taken out through the second cooking cavity 14, which is convenient for taking and putting the cooking food.
