Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a cooking utensil. Background Art

[0002] In the related art, the cooking environment inside the cooking device is close to a closed environment, and food is cooked into finished food in the closed environment.

[0003] However, in the actual cooking process, since the internal and external airflow cannot be exchanged, cooking parameters such as humidity and oxygen content in the closed environment cannot be adjusted, resulting in poor quality of the finished food. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, the present invention proposes a cooking appliance, comprising: a main body, the main body having a heat dissipation cavity and a cooking cavity, the heat dissipation cavity and the cooking cavity being communicated with each other; a heating component connected to the main body, the heating component being used to heat the food in the cooking cavity; a fan component connected to the main body, at least a portion of the fan component being located in the heat dissipation cavity, and another portion of the fan component being located in the cooking cavity, and the fan component being capable of blowing air in the heat dissipation cavity into the cooking cavity.

[0006] The cooking device provided by the utility model comprises a main body, which is a frame structure within the cooking device and is used to position, protect, and support other working structures of the cooking device. A cooking cavity is formed within the main body, into which food is placed and heated by a heating assembly to be processed into finished food.

[0007] The heating component is used to heat the food in the cooking cavity. During the heating process, the fan blade component can form a circulating airflow in the cooking cavity, so that the temperature distribution in various parts of the cooking cavity is more uniform, which is beneficial to improving the cooking effect of the food.

[0008] The heat dissipation cavity is provided with electrical components, and at least a portion of the fan assembly is located within the heat dissipation cavity. When the fan assembly is in operation, the fan assembly creates an airflow within the heat dissipation cavity. The airflow removes heat from the surface of the electrical components, thereby dissipating heat from the components and ensuring stable operation of the components. When the fan assembly is in operation, ambient air can flow into the heat dissipation cavity driven by the fan assembly, thereby reducing the temperature within the heat dissipation cavity.

[0009] Because the heat dissipation chamber and the cooking chamber are connected, when the fan assembly is in operation, the airflow in the heat dissipation chamber is driven by the fan assembly to flow into the cooking chamber. Fresh air from the outside can then flow through the heat dissipation chamber into the cooking chamber, allowing the cooking chamber to continuously draw in outside air during operation. This allows the use of outside air to adjust cooking parameters such as humidity and oxygen content in the cooking chamber to meet the cooking requirements of specific foods, resolving technical deficiencies in related technologies that result in the inability to adjust cooking parameters such as humidity and oxygen content, resulting in poor quality of the finished food.

[0010] The temperature in the heat dissipation cavity is usually higher. By blowing the air in the heat dissipation cavity to the cooking cavity, the cooking cavity can be heated up, which can not only speed up the heating speed of the food in the cooking cavity, but also reduce energy consumption.

[0011] In addition, the cooking appliance according to the above technical solution provided by the present invention may also have the following additional technical features:

[0012] In some technical solutions, optionally, the cooking appliance further includes: an air induction channel located in the body, and the heat dissipation cavity and the cooking cavity are connected through the air induction channel.

[0013] An air duct is provided between the heat dissipation cavity and the cooking cavity, and the air flow in the heat dissipation cavity can flow into the cooking cavity through the air duct. The air duct is provided on the main body for conducting the air flow, so that the air flow in the heat dissipation cavity can flow stably and smoothly to the cooking cavity, ensuring that sufficient fresh air can be added to the cooking cavity, which is beneficial to improving the cooking effect.

[0014] Of course, in other implementations, a connecting structure for connecting the heat dissipation cavity and the cooking cavity may also be provided outside the body.

[0015] In some technical solutions, optionally, the fan assembly includes a first centrifugal fan, the first centrifugal fan is located in the heat dissipation cavity, and the air induction channel is located on a peripheral side of the first centrifugal fan.

[0016] When the first centrifugal fan rotates, airflow is generated within the heat dissipation cavity, dissipating heat from the electrical components. The first centrifugal fan ejects the airflow away from the axis, causing it to flow away from the axis. Because the induced air passage is located around the first centrifugal fan, the ejected airflow passes through the induced air passage, allowing a portion of the airflow to flow into the cooking cavity. Leveraging the characteristics of the first centrifugal fan's ejected airflow, the induced air passage is located around the first centrifugal fan, thereby increasing the amount of fresh air entering the cooking cavity and improving cooking results.

[0017] In some technical solutions, optionally, the first end of the air induced channel is connected to the heat dissipation cavity, and the second end of the air induced channel is connected to the cooking cavity. From the first end of the air induced channel to the second end of the air induced channel, the air induced channel bends in a direction away from the fan assembly.

[0018] The induced air channel is disposed around the first centrifugal fan, and a first end of the induced air channel is connected to the heat dissipation chamber. The airflow ejected by the first centrifugal fan enters the induced air channel through the first end of the induced air channel. The airflow ejected by the first centrifugal fan tends to flow away from the axis, and the induced air channel curves away from the fan assembly, gradually curving along the inflow direction of the airflow. This guides the airflow, ensuring stable airflow into the cooking chamber, increasing the amount of fresh air entering the cooking chamber, and improving cooking results.

[0019] In some technical solutions, optionally, the main body further includes: a partition, the partition is used to separate the heat dissipation cavity and the cooking cavity, and an air induction channel is provided on the partition.

[0020] The heat dissipation cavity and the cooking cavity are separated by a partition. An opening is provided on the partition. The opening serves as an air induction channel for air flow, so that the gas in the heat dissipation cavity can flow into the cooking cavity.

[0021] In some technical solutions, optionally, the fan assembly includes a rotating shaft, and the rotating shaft passes through the air induction channel.

[0022] The rotating shaft passes through the air induction channel, allowing both the fan assembly located within the heat dissipation chamber and the fan assembly located within the cooking chamber to be mounted on the rotating shaft. By utilizing the position of the partition that avoids the rotating shaft to serve as the air induction channel, it eliminates the need for separate channels elsewhere on the partition, simplifying the partition structure and reducing manufacturing complexity. When the fan assembly rotates, air from the heat dissipation chamber passes through the avoidance structure on the partition and enters the cooking chamber, replenishing fresh air and ensuring optimal cooking of the ingredients.

[0023] In some technical solutions, optionally, the fan assembly also includes: a heat dissipation fan, connected to the rotating shaft, and the heat dissipation fan is located in the heat dissipation cavity; a centrifugal fan group, connected to the rotating shaft, and the centrifugal fan group is located in the cooking cavity, and the fresh air flowing into the heat dissipation cavity is drawn into the cooking cavity through the centrifugal fan group.

[0024] The cooling fan is located in the cooling chamber and is used to dissipate heat from the electrical components, thereby ensuring stable operation of the electrical components.

[0025] The centrifugal fan assembly is located within the cooking chamber and creates airflow within the cooking chamber, thereby improving temperature uniformity throughout the cooking chamber. Both the cooling fan and the centrifugal fan assembly are connected to a rotating shaft, which simultaneously drives the cooling fan and the centrifugal fan assembly. This allows a single drive source to drive both fan groups, simplifying the drive source structure.

[0026] The centrifugal fan group drives the air flow in the centrifugal direction, and negative pressure is formed at the center of the centrifugal fan group. The negative pressure area on the centrifugal fan group can suck the air in the heat dissipation cavity into the cooking cavity, thereby replenishing fresh air in the cooking cavity, which is beneficial to improving the cooking effect of the ingredients.

[0027] In some technical solutions, optionally, the centrifugal fan group includes: a second centrifugal fan, connected to the rotating shaft, the second centrifugal fan includes a plurality of second blades, and a portion of the second blades is bent toward the cooling fan; a third centrifugal fan, connected to the rotating shaft, located on a side of the second centrifugal fan away from the cooling fan, the third centrifugal fan includes a plurality of third blades, and a portion of the third blades is bent in a direction away from the cooling fan.

[0028] The centrifugal fan assembly includes two centrifugal fans: a second centrifugal fan and a third centrifugal fan. Both the second centrifugal fan and the third centrifugal fan are capable of driving airflow in a centrifugal direction. The second blades of the second centrifugal fan are bent toward the heat dissipation fan, and the airflow returning to the second centrifugal fan flows in the direction from the heat dissipation fan to the second centrifugal fan. Therefore, the airflow in the heat dissipation chamber is driven by the second centrifugal fan to flow into the cooking chamber, thereby replenishing fresh air in the cooking chamber.

[0029] The third blade in the third centrifugal fan is bent in the direction away from the heat dissipation fan, and the direction of the airflow returning to the third centrifugal fan is: the third blade is toward the direction of the second blade. This circulation method can improve the uniformity of temperature distribution in the cooking cavity.

[0030] The second centrifugal fan is located between the heat dissipation fan and the third centrifugal fan, so that the third centrifugal fan does not affect the airflow sucked by the second centrifugal fan.

[0031] In some technical solutions, optionally, the centrifugal fan group includes: a fourth blade and a fifth blade, a portion of the fourth blade is bent toward the heat dissipation fan, and a portion of the fifth blade is bent in a direction away from the heat dissipation fan.

[0032] The functions of drawing air into the heat dissipation cavity and enhancing air circulation within the cooking cavity can be integrated into a single fan. The centrifugal fan assembly includes two sets of blades, wherein the fourth blade is bent toward the heat dissipation fan, so that a portion of the airflow returning to the centrifugal fan assembly is directed from the heat dissipation fan to the centrifugal fan assembly. As a result, the airflow within the heat dissipation cavity is driven by the fourth blade to flow into the cooking cavity.

[0033] The fifth fan blade is bent in the direction away from the cooling fan, and the direction of the other part of the airflow returning to the centrifugal fan group is: the direction of the centrifugal fan group toward the cooling fan. This circulation method can improve the uniformity of temperature distribution in the cooking cavity.

[0034] In some technical solutions, optionally, the heat dissipation fan includes a centrifugal fan, the centrifugal fan includes a plurality of first fan blades, and the first fan blades are bent in a direction away from the centrifugal fan group.

[0035] The cooling fan can drive centrifugal flow, and the first fan blade in the cooling fan is bent in the direction away from the centrifugal fan group, so that the direction of the airflow returning to the cooling fan is: cooling fan to centrifugal fan group. The cooling fan is not easy to suck the airflow in the cooking cavity into the cooling cavity, ensuring that fresh air can be replenished into the cooking cavity.

[0036] In some technical solutions, optionally, an air inlet is provided on the main body, and the air inlet is communicated with the heat dissipation cavity.

[0037] When the fan assembly rotates, external air can be sucked into the heat dissipation cavity through the air inlet, thereby replenishing fresh air for the cooking cavity. Of course, in other embodiments, it is not necessary to set an air inlet on the body, and the air can be sucked into the heat dissipation cavity through the gaps between adjacent components on the body.

DETAILED DESCRIPTION

[0049] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0051] Refer to the following Figures 1 to 7 The following describes a cooking appliance provided according to some embodiments of the present invention.

[0052] like Figure 1 As shown, in an embodiment of the present invention, a cooking appliance is proposed, including: a main body 100, a heating component 200, an electrical component 300 and a fan component 400. The main body 100 has a heat dissipation cavity 110 and a cooking cavity 120. The heat dissipation cavity 110 and the cooking cavity 120 are connected. The heating component 200, the electrical component 300 and the fan component 400 are all connected to the main body 100. The heating component 200 is used to heat the food in the cooking cavity 120. The electrical component 300 is located in the heat dissipation cavity 110. At least a part of the fan component 400 is located in the heat dissipation cavity 110, and another part of the fan component 400 is located in the cooking cavity 120. The fan component 400 can blow the air in the heat dissipation cavity 110 into the cooking cavity 120.

[0053] The cooking device provided in this embodiment comprises a main body 100, which serves as the framework of the cooking device. This main body 100 is used to position, protect, and support the other working components of the cooking device. A cooking cavity 120 is formed within the main body 100. Ingredients are placed within the cooking cavity 120 and heated by the heating assembly 200 to be processed into finished food.

[0054] The heating component 200 is used to heat the food in the cooking cavity 120. During the heating process, the fan blade component can form a circulating airflow in the cooking cavity 120, so that the temperature distribution in various places in the cooking cavity 120 is relatively uniform, which is beneficial to improving the cooking effect of the food.

[0055] The heat dissipation cavity 110 is provided with an electrical component 300, and at least a portion of the fan assembly 400 is located within the heat dissipation cavity 110. When the fan assembly 400 is in operation, it creates an airflow within the heat dissipation cavity 110. This airflow removes heat from the surface of the electrical component 300, thereby dissipating heat from the electrical component 300 and ensuring stable operation of the electrical component 300. When the fan assembly 400 is in operation, external air can flow into the heat dissipation cavity 110 driven by the fan assembly 400, thereby reducing the temperature within the heat dissipation cavity 110.

[0056] Because heat dissipation chamber 110 and cooking chamber 120 are connected, when fan assembly 400 is in operation, the airflow within heat dissipation chamber 110 can flow into cooking chamber 120 driven by fan assembly 400. Fresh air from outside can flow into heat dissipation chamber 110, allowing fresh air from outside to flow into cooking chamber 120 through heat dissipation chamber 110, allowing cooking chamber 120 to continuously draw in outside air during operation. This allows the use of outside air to adjust cooking parameters such as humidity and oxygen content within cooking chamber 120 to meet the cooking requirements of specific foods, thereby resolving the technical drawbacks of related technologies, such as the inability to adjust cooking parameters such as humidity and oxygen content, resulting in poor quality of the finished food.

[0057] The temperature in the heat dissipation cavity 110 is usually high. By blowing the air in the heat dissipation cavity 110 to the cooking cavity 120, the cooking cavity 120 can be heated up, which can not only speed up the heating speed of the food in the cooking cavity 120, but also reduce energy consumption.

[0058] In a possible application, the heating assembly 200 may be a heating tube or a heating wire, etc. The electrical device 300 may be a controller, a driving component of the fan assembly 400, etc.

[0059] like Figure 1 As shown, in some embodiments, optionally, the cooking appliance further includes: an air induction channel 130 , which is located in the body 100 , and the heat dissipation cavity 110 and the cooking cavity 120 are connected through the air induction channel 130 .

[0060] An air induction channel 130 is provided between the heat dissipation cavity 110 and the cooking cavity 120. The air flow in the heat dissipation cavity 110 can flow into the cooking cavity 120 through the air induction channel 130. The air induction channel 130 for conducting the air flow is provided on the main body 100, so that the air flow in the heat dissipation cavity 110 can flow stably and smoothly to the cooking cavity 120, ensuring that sufficient fresh air can be added to the cooking cavity 120, which is conducive to improving the cooking effect.

[0061] Of course, in other implementations, a connecting structure for connecting the heat dissipation cavity 110 and the cooking cavity 120 may also be provided outside the body 100 .

[0062] like Figure 1 As shown, in some embodiments, optionally, the fan assembly 400 includes a first centrifugal fan 410 , the first centrifugal fan 410 is located in the heat dissipation cavity 110 , and the air induction channel 130 is located around the first centrifugal fan 410 .

[0063] When the first centrifugal fan 410 rotates, airflow is formed in the heat dissipation cavity 110, thereby dissipating heat from the electrical device 300. The first centrifugal fan 410 throws the airflow in a direction away from the axis, so that the airflow flows in a direction away from the axis. Since the air induction channel 130 is arranged on the peripheral side of the first centrifugal fan 410, the thrown airflow passes through the air induction channel 130 ( Figure 1 The curve extending within central air induction channel 130 indicates the direction of airflow, allowing a portion of the airflow to flow into cooking cavity 120. Leveraging the airflow ejected by first centrifugal fan 410, air induction channel 130 is positioned around first centrifugal fan 410, increasing the amount of fresh air entering cooking cavity 120 and improving cooking performance.

[0064] The fan assembly 400 further includes a circulation fan 420 . The circulation fan 420 is located in the cooking cavity 120 . The circulation fan 420 is used to form a circulating airflow in the cooking cavity 120 .

[0065] like Figure 1 As shown, in some embodiments, optionally, the first end of the air induced channel 130 is connected to the heat dissipation cavity 110, and the second end of the air induced channel 130 is connected to the cooking cavity 120, and from the first end of the air induced channel 130 to the second end of the air induced channel 130, the air induced channel 130 is bent in a direction away from the fan assembly 400.

[0066] The induced air passage 130 is disposed around the first centrifugal fan 410, and a first end of the induced air passage 130 communicates with the heat dissipation chamber 110. The airflow ejected by the first centrifugal fan 410 enters the induced air passage 130 through the first end of the induced air passage 130. The airflow ejected by the first centrifugal fan 410 tends to flow away from the axis, and the induced air passage 130 curves away from the fan assembly 400. Thus, the induced air passage 130 gradually curves along the inflow direction of the airflow. This guides the airflow, ensuring that it flows stably into the cooking chamber 120, increasing the amount of fresh air entering the cooking chamber 120, and improving the cooking effect.

[0067] Combine Figure 2 and Figure 3 As shown, in some embodiments, optionally, the body 100 further includes: a partition 140 , the partition 140 is used to separate the heat dissipation cavity 110 and the cooking cavity 120 , and an air induction channel 130 is provided on the partition 140 .

[0068] The heat dissipation cavity 110 and the cooking cavity 120 are separated by a partition 140 , and an opening is provided on the partition 140 . The opening serves as an air induction channel for air flow, so that the gas in the heat dissipation cavity 110 can flow into the cooking cavity 120 .

[0069] Combine Figure 2 and Figure 3 As shown, in some embodiments, optionally, the fan assembly 400 includes a rotating shaft 450 , and the rotating shaft 450 passes through the air induction channel 130 .

[0070] The heat dissipation chamber 110 and the cooking chamber 120 are separated by a partition 140. An air induction channel 130 is provided on the partition 140, and a rotating shaft 450 passes through the air induction channel 130. This allows a portion of the fan assembly 400 located within the heat dissipation chamber 110 and a portion of the fan assembly 400 located within the cooking chamber 120 to be mounted on the rotating shaft 450. By utilizing the position of the partition 140 that avoids the rotating shaft 450 to function as the air induction channel 130, it is unnecessary to provide a separate channel elsewhere on the partition 140, simplifying the structure of the partition 140 and reducing manufacturing complexity. When the fan assembly 400 rotates, air from the heat dissipation chamber 110 passes through the avoidance structure on the partition 140 and enters the cooking chamber 120, replenishing fresh air within the cooking chamber 120 and ensuring optimal cooking of the food.

[0071] In a possible application, the rotating shaft 450 is used to be connected to a driving component that drives the fan assembly 400 to rotate, or the rotating shaft 450 is a part of the driving component.

[0072] Combine Figure 2 and Figure 4As shown, in some embodiments, optionally, the fan assembly 400 further includes: a heat dissipation fan 430 and a centrifugal fan group 440, the heat dissipation fan 430 and the centrifugal fan group 440 are both connected to the rotating shaft 450, the heat dissipation fan 430 is located in the heat dissipation cavity 110, and the centrifugal fan group 440 is located in the cooking cavity 120 ( Figure 2 The curve in the cooking cavity 120 is used to represent the airflow circulation path), and the fresh air flowing into the heat dissipation cavity 110 is drawn into the cooking cavity 120 through the centrifugal fan group 440.

[0073] The heat dissipation fan 430 is located in the heat dissipation cavity 110 . The heat dissipation fan 430 is used to dissipate heat from the electrical device 300 , thereby ensuring stable operation of the electrical device 300 .

[0074] A centrifugal fan assembly 440 is located within cooking cavity 120 and is used to create airflow within cooking cavity 120, thereby improving temperature uniformity throughout cooking cavity 120. Both cooling fan 430 and centrifugal fan assembly 440 are connected to a rotating shaft 450. Rotating shaft 450 simultaneously drives both the cooling fan and centrifugal fan assembly 440, simplifying the drive source structure by driving both fan groups.

[0075] The centrifugal fan group 440 drives the air flow to flow in a centrifugal direction, and negative pressure is formed at the center of the centrifugal fan group 440. The negative pressure area on the centrifugal fan group 440 can suck the air flow in the heat dissipation cavity 110 into the cooking cavity 120, thereby replenishing fresh air in the cooking cavity 120, which is beneficial to improving the cooking effect of the ingredients.

[0076] When the centrifugal fan group 440 is working, the central area is in a negative pressure state, and the negative pressure is used to draw air from the heat dissipation cavity 110 through the air induction channel 130 into the center of the centrifugal fan group 440, and then evenly thrown out to various positions of the cooking cavity 120.

[0077] Combine Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, optionally, the centrifugal fan group 440 includes: a second centrifugal fan 441 and a third centrifugal fan 444, the second centrifugal fan 441 and the third centrifugal fan 444 are both connected to the rotating shaft 450, the second centrifugal fan 441 includes a plurality of second blades 442, a portion of the second blades 442 is bent toward the heat dissipation fan 430, the third centrifugal fan 444 is located on the side of the second centrifugal fan 441 away from the heat dissipation fan 430, the third centrifugal fan 444 includes a plurality of third blades 445, a portion of the third blades 445 is bent in a direction away from the heat dissipation fan 430.

[0078] The centrifugal fan group 440 includes two groups of centrifugal fans, namely a second centrifugal fan 441 and a third centrifugal fan 444. The second centrifugal fan 441 and the third centrifugal fan 444 are both capable of driving the airflow in a centrifugal direction. Among them, the second fan blades 442 of the second centrifugal fan 441 are bent toward the heat dissipation fan 430, and the airflow returning to the second centrifugal fan 441 flows in the direction from the heat dissipation fan 430 to the second centrifugal fan 441 ( Figure 5 The boxed area is used to represent the negative pressure area on the second centrifugal fan 441), therefore, the air flow in the heat dissipation cavity 110 will flow into the cooking cavity 120 driven by the second centrifugal fan 441, thereby replenishing fresh air in the cooking cavity 120.

[0079] The third blades 445 in the third centrifugal fan 444 are bent in a direction away from the heat dissipation fan 430, and the direction of the airflow returning to the third centrifugal fan 444 is: the third blades 445 are toward the direction of the second blades 442. This circulation method can improve the uniformity of temperature distribution in the cooking cavity 120.

[0080] The second centrifugal fan 441 is located between the heat dissipation fan 430 and the third centrifugal fan 444 , so that the third centrifugal fan 444 does not affect the airflow sucked by the second centrifugal fan 441 .

[0081] The two centrifugal fans can enhance air convection in the cooking cavity 120 and improve the cooking effect of the cooking cavity 120 .

[0082] Second centrifugal fan 441 further includes a second mounting portion 443, second blades 442 are integrally provided with second mounting portion 443, and second mounting portion 443 is sleeved and mounted on rotating shaft 450. Third centrifugal fan 444 further includes a third mounting portion 446, third blades 445 are integrally provided with third mounting portion 446, and third mounting portion 446 is sleeved and mounted on rotating shaft 450.

[0083] like Figure 6 As shown, in some embodiments, optionally, the centrifugal fan group 440 includes: a fourth blade 447 and a fifth blade 448, a portion of the fourth blade 447 is bent toward the heat dissipation fan 430, and a portion of the fifth blade 448 is bent in a direction away from the heat dissipation fan 430.

[0084] The functions of drawing air into heat dissipation cavity 110 and enhancing air circulation within cooking cavity 120 can be integrated into a single fan. Centrifugal fan assembly 440 includes two sets of blades, wherein fourth blade 447 is bent toward heat dissipation fan 430, so that a portion of the airflow returning to centrifugal fan assembly 440 is directed from heat dissipation fan 430 to centrifugal fan assembly 440. Therefore, airflow within heat dissipation cavity 110 is driven by fourth blade 447 to flow into cooking cavity 120.

[0085] The fifth fan blade 448 is bent in the direction away from the heat dissipation fan 430, and the direction of the other part of the air flow returning to the centrifugal fan group 440 is: the centrifugal fan group 440 is toward the heat dissipation fan 430. This circulation method can improve the uniformity of temperature distribution in the cooking cavity 120.

[0086] The fourth blade 447 and the fifth blade 448 are simplified to a centrifugal fan group 440, wherein the inner ring and outer ring blade folds of the centrifugal fan group 440 are reversed, and the central negative pressure is used to inhale fresh air.

[0087] like Figure 4 As shown, in some embodiments, optionally, the heat dissipation fan 430 includes a centrifugal fan, and the centrifugal fan includes a plurality of first blades 431 , and the first blades 431 are bent in a direction away from the centrifugal fan group 440 .

[0088] The cooling fan 430 can drive centrifugal flow, and the first fan blade 431 in the cooling fan 430 is bent in the direction away from the centrifugal fan group 440, so that the direction of the air flow returning to the cooling fan 430 is: from the cooling fan 430 to the centrifugal fan group 440. The cooling fan 430 is not easy to suck the air flow in the cooking cavity 120 into the cooling cavity 110, ensuring that fresh air can be replenished into the cooking cavity 120.

[0089] The heat dissipation fan 430 further includes a first mounting portion 432 . The first blade 431 and the first mounting portion 432 are integrally provided. The first mounting portion 432 is sleeved and mounted on the rotating shaft 450 .

[0090] like Figure 7 As shown, in some embodiments, optionally, an air inlet 150 is provided on the main body 100 , and the air inlet 150 is communicated with the heat dissipation cavity 110 .

[0091] When the fan assembly 400 rotates, external air can be drawn into the heat dissipation cavity 110 through the air inlet 150, thereby replenishing fresh air for the cooking cavity 120. Of course, in other embodiments, the air inlet 150 may not be provided on the body 100, and the air can be drawn into the heat dissipation cavity 110 through gaps between adjacent components on the body 100.

[0092] In this manner, when fan assembly 400 is in operation, the airflow within heat dissipation cavity 110 is driven by fan assembly 400 to flow into cooking cavity 120. Fresh air from outside can flow into heat dissipation cavity 110, allowing fresh air from outside to flow into cooking cavity 120 through heat dissipation cavity 110, allowing cooking cavity 120 to continuously draw in outside air during operation. This allows the use of outside air to adjust cooking parameters such as humidity and oxygen content within cooking cavity 120 to meet the cooking requirements of specific foods, thereby resolving the technical drawbacks of related technologies, such as the inability to adjust cooking parameters such as humidity and oxygen content, resulting in poor quality of the finished food.
