Description

Technical Field

[0001] The present invention relates to the technical field of cooking equipment, and in particular to a cooking equipment. Background Art

[0002] The current air frying system usually stacks a motor, a fan blade, and a heating tube, making the entire air frying assembly thick and heavy. In order to reduce the thickness, some air frying systems on the market separate the heating tube and place it in a container for cooking food. However, the setting method of the existing technology will cause the maximum heating temperature to be lowered, which has a certain negative impact on the cooking effect. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] In view of this, an embodiment of the present invention provides a cooking device.

[0005] In order to achieve the above-mentioned purpose, an embodiment of the present invention provides a cooking device, including: a shell, in which a cooking cavity and a heating cavity are connected; an air duct is arranged on the outer wall of the cooking cavity, the air duct is connected to the heating cavity, and a fan is arranged in the air duct; a heating element is arranged in the heating cavity, and the heating element and the fan are arranged along the long side direction of the cooking cavity; wherein the air heated by the heating element can flow into the cooking cavity.

[0006] The cooking device provided according to the embodiment of the present invention mainly includes a shell and an air duct, wherein the shell is hollow inside, and a cooking cavity and a heating cavity are arranged inside, the cooking cavity is mainly used for cooking food, and the heating cavity is used to generate heat for heating and cooking food. Specifically, an air duct is arranged on the outer wall of the cooking cavity, which can reduce the occupation of the internal cooking space and ensure the cooking volume. On this basis, a fan is arranged in the air duct so as to drive the air to flow during operation. In particular, in this scheme, the heating cavity and the air duct are both arranged outside the cooking cavity, and the heating element and the fan are arranged along the long side direction of the cooking cavity, so that the size of the entire cooking device in the direction perpendicular to the long side direction of the cooking cavity can be greatly reduced. It can be understood that on the basis of the air duct, the air will flow to the heating element after being driven by the fan, so that the air can be heated under the action of the heating element and then flow into the cooking cavity, thereby completing the cooking of the food.

[0007] It should be emphasized that in the present application, there can be a certain gap between the heating element and the fan, or they can be placed directly adjacent to each other. As long as the heating element is arranged horizontally on one side of the fan, the size of the entire cooking device in the extension direction perpendicular to the outer wall of the cooking cavity with the air duct can be reduced, thereby achieving a thin design and usage requirements.

[0008] Among them, the cooking equipment is a device that uses air to heat food, and can be an air fryer.

[0009] Furthermore, the fan may be selected as one or more of a centrifugal fan, an axial flow fan, and a cross flow fan.

[0010] In the above technical solution, the air inlet direction of the fan is perpendicular to the long side direction of the cooking cavity, and the air outlet direction of the fan is parallel to the long side direction of the cooking cavity; wherein, the air inlet direction is the direction in which air flows from the cooking cavity into the fan, and the air outlet direction is the direction in which air flows from the fan to the heating element.

[0011] In this technical solution, by limiting the air inlet direction and air outlet direction of the fan to be perpendicular, the overall air flow direction is better satisfied. Specifically, the air inlet direction of the fan is perpendicular to the direction of the outer wall of the cooking cavity provided with the air duct. At this time, the air will flow into the fan from the cooking cavity through the outer wall of the cooking cavity. Under the action of the fan located outside the cooking cavity, the air in the cooking cavity will continuously flow into the air duct, and then flow along the direction parallel to the long side of the cooking cavity to the heating element for heating, and finally flow back into the cooking cavity.

[0012] The fan may be a centrifugal fan.

[0013] The above technical solution also includes: a first air outlet is arranged on the outer wall of the cooking cavity, and the first air outlet is arranged opposite to the fan.

[0014] In this technical solution, a first air outlet is provided on the outer wall of the cooking cavity. Since the first air outlet is arranged opposite to the fan, the air in the cooking cavity will flow into the fan through the first air outlet, thereby facilitating subsequent continuous delivery to the air duct to facilitate cooking of the ingredients.

[0015] The first air outlet may be understood as an opening on the outer wall of the cooking cavity that is connected to the ventilator and the cooking cavity.

[0016] In the above technical solution, the first air outlet specifically includes a plurality of first through holes, and the plurality of first through holes are arranged in an array around the axis of the air inlet of the fan; wherein the shapes corresponding to the plurality of first through holes are adapted to the shape of the air inlet.

[0017] In this technical solution, the first air outlet includes a first through hole with a plurality of circumferential array arrangements, and the plurality of first through holes are arranged around the axis of the air inlet of the fan. At the same time, the shape formed by the plurality of first through holes is limited to match the shape of the air inlet, so as to utilize the area of ​​the air inlet of the fan, ensure the air intake, and meet cooking requirements.

[0018] In the above technical solution, the maximum projection pattern formed by the plurality of first through holes on the outer wall of the cooking cavity provided with the air duct covers the projection of the air inlet on the outer wall of the cooking cavity.

[0019] In this technical solution, by limiting the projection of the plurality of first through holes on the outer wall of the cooking cavity, the projection of the air outlet will be covered, so as to make full use of the area of ​​the air inlet of the fan, greatly meet the air intake demand, and ensure the flow of air volume.

[0020] It can be understood that the projection surface is the outer wall of the cooking cavity provided with the air duct, and may also be another wall surface parallel to the outer wall of the cooking cavity.

[0021] The above technical solution also includes: a second air port is arranged on the outer wall of the cooking cavity, and the second air port is arranged opposite to the heating element.

[0022] In this technical solution, a second air outlet is arranged on the outer wall of the cooking cavity opposite to the heating element. Since the second air outlet is arranged opposite to the heating element, the air in the air duct will flow into the cooking cavity through the second air outlet, thereby facilitating the subsequent cooking of the ingredients.

[0023] The second air vent may be understood as an opening on the outer wall of the cooking cavity connecting the heating element and the cooking cavity.

[0024] In the above technical solution, the second air outlet specifically includes a plurality of second through holes, and the maximum projection pattern formed by the plurality of second through holes on the outer wall of the cooking cavity covers the projection of the heating element on the outer wall of the cooking cavity.

[0025] In this technical solution, the second air outlet includes a plurality of second through holes, and the projections of the plurality of first through holes are limited on the outer wall of the cooking cavity to cover the projection of the air outlet, so as to make full use of the area of ​​the air inlet of the fan, greatly meet the air intake demand, and ensure the flow of air volume.

[0026] In the above technical solution, the cooking cavity and the heating cavity are arranged along the height direction of the shell; or the cooking cavity and the heating cavity are arranged along the front-rear direction of the shell.

[0027] In this technical solution, the relative position between the cooking cavity and the heating cavity can be set along the height direction, or along the front-to-back direction of the shell. No matter which setting method is used, the size of the cooking device in this direction can be reduced. Specifically, if the cooking cavity and the heating cavity are set on both sides of the outer wall of the cooking cavity with the air duct along the height direction of the shell, the size of the entire cooking device in the height direction will be reduced because the heating element and the fan are set along the extension direction of the outer wall of the cooking cavity. Similarly, if the cooking cavity and the heating cavity are set on both sides of the outer wall of the cooking cavity with the air duct along the front-to-back direction of the shell, the size of the entire cooking device in the front-to-back direction will be reduced because the heating element and the fan are set along the extension direction of the outer wall of the cooking cavity.

[0028] The above technical solution also includes: a delivery port, which is arranged on the shell; and a door body, which is rotatably connected to the shell, and the door body is used to open and close the delivery port.

[0029] In this technical solution, a loading port is provided on the shell, and a door body rotatably connected to the shell is also provided. When the door body is opened, it is convenient to put food into the cooking cavity, or take out the cooked food from the cooking cavity.

[0030] In the above technical solution, the fan specifically includes: a motor, a drive shaft is provided at one end of the outer wall of the cooking cavity facing the air duct; a first fan blade is connected to the drive shaft, and the first fan blade rotates to dissipate the heat of the motor; a second fan blade is connected to the drive shaft, and the second fan blade rotates to drive air to flow to the cooking cavity through the heating element.

[0031] In this technical solution, the fan mainly includes a motor and two fan blades arranged on the motor, namely a first fan blade and a second fan blade, wherein the first fan blade mainly plays the effect of dissipating the heat of the motor when rotating, and the second fan blade is used to drive the air to flow in the air duct. By arranging two fan blades on one motor at the same time, the size of the entire motor in the extension direction perpendicular to the outer wall of the cooking cavity is reduced.

[0032] Among them, the first fan blade and the second fan blade are respectively connected to the drive shaft, and the specific rotation directions can be the same or different, as long as the first fan blade can achieve the effect of dissipating heat for the motor and the second fan blade can achieve the effect of driving the air in the air duct when the drive shaft rotates.

[0033] Additional aspects and advantages of the present invention will become apparent from the following description or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0043] Refer to the following Figures 1 to 5 Some embodiments according to the invention are described.

[0044] Embodiment 1

[0045] like Figure 1 and Figure 4 As shown, a cooking device 100 proposed in this embodiment mainly includes a shell 102 and an air duct 104, wherein the shell 102 is hollow inside, and is provided with a cooking cavity 1032 and a heating cavity 1034 inside, the cooking cavity 1032 is mainly used for cooking food, and the heating cavity 1034 is used to generate heat for heating and cooking the food. Specifically, an air duct is provided on the outer wall of the cooking cavity, which can reduce the occupation of the internal cooking space and ensure the cooking volume. On this basis, a fan 105 is provided in the air duct 104, so as to drive the air to flow during operation. In particular, in this solution, the heating element 1042 and the fan 105 are provided along the long side direction of the cooking cavity, so that the size of the entire cooking device 100 in the direction perpendicular to the long side direction of the cooking cavity can be greatly reduced. It can be understood that on the basis of setting up the air duct 104, the air will be driven by the fan 105 and flow to the heating element 1042, so that the air can be heated under the action of the heating element 1042 and then flow into the cooking cavity 1032, thereby completing the cooking of the ingredients.

[0046] It should be emphasized that in the present application, there can be a certain gap between the heating element 1042 and the fan 105, or they can be placed directly adjacent to each other. As long as the heating element 1042 is horizontally arranged on one side of the fan 105, the size of the entire cooking device 100 in the direction perpendicular to the extension of the outer wall 1022 of the cooking cavity can be reduced, thereby achieving a thin design and usage requirements.

[0047] The cooking device 100 is a device that utilizes air to heat food, and may be an air fryer.

[0048] Furthermore, the fan 105 may be selected as one or more of a centrifugal fan 105 , an axial flow fan 105 , and a cross flow fan 105 .

[0049] In a specific embodiment, the air inlet direction and the air outlet direction of the fan 105 are perpendicular to each other, which is more in line with the overall air flow direction. Specifically, the air inlet direction of the fan 105 is perpendicular to the direction in which the outer wall 1022 of the cooking cavity provided with the air duct extends. At this time, the air will flow into the fan from the cooking cavity through the outer wall of the cooking cavity. Under the action of the fan 105 located outside the cooking cavity, the air in the cooking cavity 1032 will continuously flow into the air duct 104, and then flow along the direction parallel to the long side of the cooking cavity to the heating element 1042 for heating, and finally flow back into the cooking cavity 1032.

[0050] The fan 105 may be a centrifugal fan 105 .

[0051] In a specific embodiment, the relative position between the cooking cavity 1032 and the heating cavity 1034 can be set along the height direction. Since the heating element 1042 and the fan 105 are arranged along the extension direction of the outer wall 1022 of the cooking cavity, the size of the entire cooking device 100 in the height direction will be reduced.

[0052] In another specific embodiment, the relative position between the cooking cavity 1032 and the heating cavity 1034 can be set along the front-to-back direction of the shell 102. Since the heating element 1042 and the fan 105 are set along the extension direction of the outer wall 1022 of the cooking cavity, the size of the entire cooking device 100 in the front-to-back direction will be reduced.

[0053] Embodiment 2

[0054] like Figure 1 and Figure 4As shown, a cooking device 100 proposed in this embodiment mainly includes a shell 102 and an air duct 104, wherein the shell 102 is hollow inside, and is provided with a cooking cavity 1032 and a heating cavity 1034 inside, the cooking cavity 1032 is mainly used for cooking food, and the heating cavity 1034 is used to generate heat for heating and cooking the food. Specifically, an air duct is provided on the outer wall of the cooking cavity, which can reduce the occupation of the internal cooking space and ensure the cooking volume. On this basis, a fan 105 is provided in the air duct 104, so as to drive the air to flow during operation. In particular, in this solution, the heating element 1042 and the fan 105 are provided along the long side direction of the cooking cavity, so that the size of the entire cooking device 100 in the direction perpendicular to the long side direction of the cooking cavity can be greatly reduced. It can be understood that on the basis of setting up the air duct 104, the air will be driven by the fan 105 and flow to the heating element 1042, so that the air can be heated under the action of the heating element 1042 and then flow into the cooking cavity 1032, thereby completing the cooking of the ingredients.

[0055] It should be emphasized that in the present application, there can be a certain gap between the heating element 1042 and the fan 105, or they can be placed directly adjacent to each other. As long as the heating element 1042 is horizontally arranged on one side of the fan 105, the size of the entire cooking device 100 in the direction perpendicular to the extension of the outer wall 1022 of the cooking cavity can be reduced, thereby achieving a thin design and usage requirements.

[0056] The cooking device 100 is a device that utilizes air to heat food, and may be an air fryer.

[0057] A first air vent 1023 is provided on the outer wall 1022 of the cooking cavity. Since the first air vent 1023 is arranged opposite to the fan 105, the air in the cooking cavity 1032 will flow into the fan 105 through the first air vent 1023, and then be continuously transported to the air duct 104 to facilitate cooking of the food.

[0058] The first air outlet 1023 may be understood as an opening of the ventilator 105 connected to the outer wall 1022 of the cooking cavity and the cooking cavity 1032 .

[0059] Furthermore, if Figure 3 As shown, the first air outlet 1023 includes a plurality of first through holes 1024 arranged in a circumferential array. The plurality of first through holes 1024 are arranged around the axis of the air inlet of the fan 105. At the same time, the shape formed by the plurality of first through holes 1024 is limited to match the shape of the air inlet, so as to utilize the area of ​​the air inlet of the fan 105, ensure the air intake, and meet cooking requirements.

[0060] Furthermore, on the outer wall 1022 of the cooking cavity provided with the air duct, the projections of the plurality of first through holes 1024 will cover the projections of the air outlet, so as to fully utilize the area of ​​the air inlet of the fan 105, greatly meet the air intake demand, and ensure the flow of air volume.

[0061] Of course, the specific projection surface may also be another wall surface parallel to the plane where the outer wall of the cooking cavity provided with the air duct is located.

[0062] Embodiment 3

[0063] like Figure 1 and Figure 2 As shown, a cooking device 100 proposed in this embodiment mainly includes a shell 102 and an air duct 104, wherein the shell 102 is hollow inside, and is provided with a cooking cavity 1032 and a heating cavity 1034 inside, the cooking cavity 1032 is mainly used for cooking food, and the heating cavity 1034 is used to generate heat for heating and cooking the food. Specifically, an air duct is provided on the outer wall of the cooking cavity, which can reduce the occupation of the internal cooking space and ensure the cooking volume. On this basis, a fan 105 is provided in the air duct 104, so as to drive the air to flow during operation. In particular, in this solution, the heating element 1042 and the fan 105 are provided along the long side direction of the cooking cavity, so that the size of the entire cooking device 100 in the direction perpendicular to the long side direction of the cooking cavity can be greatly reduced. It can be understood that, based on the arrangement of the air duct 104, the air will flow to the heating element 1042 after being driven by the fan 105, so that the air can be heated under the action of the heating element 1042 and then flow into the cooking cavity 1032, thereby completing the cooking of the food. It should be emphasized that in the present application, there can be a certain gap between the heating element 1042 and the fan 105, or they can be placed directly adjacent to each other. As long as the heating element 1042 is horizontally arranged on one side of the fan 105, the size of the entire cooking device 100 in the direction perpendicular to the extension direction of the outer wall 1022 of the cooking cavity can be reduced, thereby achieving a thin design and usage requirements.

[0064] The cooking device 100 is a device that utilizes air to heat food, and may be an air fryer.

[0065] Furthermore, a second air vent 1025 is provided on the outer wall 1022 of the cooking cavity opposite to the heating element 1042. Since the second air vent 1025 is opposite to the heating element 1042, the air in the air duct 104 flows into the cooking cavity 1032 through the second air vent 1025, thereby facilitating the subsequent cooking of the ingredients.

[0066] The second air outlet 1025 may be understood as an opening on the outer wall 1022 of the cooking cavity that connects the heating element 1042 and the cooking cavity 1032 .

[0067] like Figure 3 As shown, the second air outlet 1025 includes a plurality of second through holes 1026, which can cover the projection of the air outlet by limiting the projection of the plurality of first through holes 1024 on the outer wall 1022 of the cooking cavity, so as to make full use of the area of ​​the air inlet of the fan 105, greatly meet the air intake demand, and ensure the flow of air.

[0068] Embodiment 4

[0069] like Figure 5 As shown, a cooking device 100 proposed in this embodiment mainly includes a shell 102 and an air duct 104, wherein the shell 102 is hollow inside, and is provided with a cooking cavity 1032 and a heating cavity 1034 inside, the cooking cavity 1032 is mainly used for cooking food, and the heating cavity 1034 is used to generate heat for heating and cooking the food. Specifically, an air duct is provided on the outer wall of the cooking cavity, which can reduce the occupation of the internal cooking space and ensure the cooking volume. On this basis, a fan 105 is provided in the air duct 104, so as to drive the air to flow during operation. In particular, in this solution, the heating element 1042 and the fan 105 are provided along the long side direction of the cooking cavity, so that the size of the entire cooking device 100 in the direction perpendicular to the long side direction of the cooking cavity can be greatly reduced. It can be understood that on the basis of setting up the air duct 104, the air will be driven by the fan 105 and flow to the heating element 1042, so that the air can be heated under the action of the heating element 1042 and then flow into the cooking cavity 1032, thereby completing the cooking of the ingredients.

[0070] A loading port is provided on the shell 102 , and a door body rotatably connected to the shell 102 is also provided. When the door body is opened, it is convenient to put food into the cooking cavity 1032 , or to take out the cooked food from the cooking cavity 1032 .

[0071] As for the fan 105, the fan 105 mainly includes a motor 1052 and two fan blades arranged on the motor 1052, namely a first fan blade 1054 and a second fan blade 1056, wherein the first fan blade 1054 mainly plays the effect of dissipating the heat of the motor 1052 when rotating, and the second fan blade 1056 is used to drive the air to flow in the air duct 104. By arranging two fan blades on one motor 1052 at the same time, the size of the entire motor 1052 in the extension direction perpendicular to the outer wall 1022 of the cooking cavity is reduced.

[0072] Furthermore, the first fan blade and the second fan blade are respectively connected to the drive shaft in a transmission manner, and the specific rotation directions may be the same or different, as long as the first fan blade can achieve the effect of dissipating heat for the motor and the second fan blade can achieve the effect of driving the air in the air duct when the drive shaft rotates.

[0073] In a specific embodiment, the first blade and the second blade rotate in the same direction.

[0074] In another specific embodiment, the first blade and the second blade rotate in opposite directions.

[0075] In a specific embodiment, an ultra-thin air frying system structure is provided, and the overall height dimension of the air frying assembly is only 55 mm. After the hot air motor 1052 (i.e., the motor 1052) is powered on, it drives the heat dissipation fan blade (i.e., the first fan blade 1054) and the hot air fan blade (i.e., the second fan blade 1056) to rotate by self-rotation. The heat dissipation fan blade dissipates heat from the hot air motor 1052, so that the hot air motor 1052 can continue to rotate at a high speed. Through the design of the fan blades, the hot air fan blade continuously transports air through the air duct 104 cover plate (i.e., the air duct 104) during the rotation process to the metal heating pipe (i.e., the heating element). The air is heated to a maximum of 230 degrees Celsius through the metal heating pipe, and then blown to the closed cavity (i.e., the cooking cavity 1032) through the exhaust hole (i.e., the second air outlet 1025) to heat the food. The air after acting on the food is sucked into the air duct 104 cover plate through the exhaust hole (i.e., the first air outlet 1023) through the negative pressure formed by the hot air fan blade to continue heating, so that the hot air circulates in the closed space. In the above embodiment, by arranging the hot air fan blades and the metal heating tubes in parallel, the thickness of the air frying system is greatly reduced, and the product is flattened. In the above embodiment, by continuously driving the air to circulate in the air duct 104 cover and the closed cavity, the cooking effect is significantly improved.

[0076] For this specific embodiment, the thickness of the air frying system can be reduced, the product can be flattened, the product shape can be expanded, and at the same time, hot air can be efficiently circulated in a closed space to improve the cooking effect.

[0077] According to the cooking device provided by the present invention, the heating element and the fan are both arranged outside the cooking cavity, and are arranged along the long side direction of the entire cooking cavity, thereby reducing the size of the entire cooking device in a direction perpendicular to the outer wall of the cooking cavity.
