[0054] As Figures 1 to 10 As shown, according to an embodiment of the present invention, a cooking appliance 100 is provided. The cooking appliance 100 includes a body 10 for embedded installation in a cabinet. A blower assembly 18, a heat dissipation air duct, and a cooking cavity 17 are provided in the body 10. Among them, the heat dissipation air duct has an air outlet hole 191 and an air inlet hole 1321.

[0055] Specifically, an embedded space with a front-end opening is provided at a preset position of the cabinet. The body 10 is embedded in the embedded space through the opening of the embedded space. The surface of the body 10 facing the outside of the embedded space (which may also be referred to as the front surface) may be flush with the opening of the embedded space, may protrude relative to the opening of the embedded space, or may be recessed relative to the opening of the embedded space.

[0056] In the present application, the front surface of the body 10 is flush with the opening of the embedded space, so that after the body 10 is embedded in the cabinet, structural supplementation can be achieved at the position of the embedded space, reducing structural protrusions and improving the overall coordination and consistency of the cabinet.

[0057] As Figure 1As shown, when the machine body 10 is embedded in a cabinet and the user faces the machine body 10, the side of the machine body 10 facing the user is the front side, the side of the machine body 10 facing away from the user is the rear side, the side of the machine body 10 facing the ground is the bottom side, the side of the machine body 10 facing away from the ground is the top side, the side of the machine body 10 on the user's left hand side is the left side, and the side of the machine body 10 on the user's right hand side is the right side. The left and right sides are arranged in the length direction X of the machine body 10, the front and rear sides are arranged in the width direction Y, and the bottom and top sides are arranged in the height direction Z.

[0058] In this application, if Figure 2 and Figure 3 As shown, the body 10 includes a cooking cavity 17, a fan assembly 18 and a heat dissipation duct. The heat dissipation duct includes an air inlet 1321 and an air outlet 191. The fan assembly 18 is arranged in the heat dissipation duct. Under the drive of the fan assembly 18, the external air flow enters the heat dissipation duct through the air inlet 1321, and the air flow in the heat dissipation duct can flow out to the outside through the air outlet 191.

[0059] Among them, the body 10 includes a cavity component 13 and an outer cover 11, the cavity component 13 surrounds a cooking cavity 17, the outer cover 11 is arranged on the outside of the cavity component 13, the outer cover 11 and part of the outer surface of the cavity component 13 surround at least part of the heat dissipation duct, and a wind guide structure 111 is formed on part of the edge of the outer cover 11, and the wind guide structure 111 and the cavity component surround an air outlet 191, the cooking cavity 17 includes a take-in and put-out port, the direction of the air outlet 191 is the same as that of the take-in and put-out port, and the air outlet 191 is configured to exhaust air from the front side of the body 10.

[0060] The access opening of the cooking cavity 17 is located on the front side of the body 10, and the user can put food in or take it out of the cooking cavity 17 through the access opening. The shape of the access opening includes but is not limited to rectangular, circular, elliptical or other shapes. The shape of the cooking cavity 17 includes but is not limited to a rectangular space, a circular space or an ellipsoidal space. At the same time, the opening area of the access opening can be the same as or different from the area of the cooking cavity 17 in the longitudinal section (the surface parallel to the front face of the body 10). For example, the cooking cavity 17 is a rectangular space, and the shape of the longitudinal section is a quadrilateral. In this case, the shape of the access opening is also a quadrilateral. The shape of the access opening is consistent with the shape of the longitudinal section of the cooking cavity 17, and the intersection of the two is equal. This arrangement makes it convenient for the user to put food in or take it out of the cooking cavity 17, thereby improving the convenience of the user during use.

[0061] The access opening of the cooking cavity 17 is located on the front side of the body 10, that is, the access opening is arranged facing forward, and the air outlet hole 191 is also located on the front side of the body 10, that is, the air outlet hole 191 is also arranged facing forward (that is, the air outlet hole 191 is configured to discharge air in a direction away from the cabinet). At this time, the orientation of the access opening is the same as that of the air outlet hole 191. When the air flow in the heat dissipation air duct is discharged through the air outlet hole 191, the air flow is discharged through the front side of the body 10. By setting the air flow to be discharged forward, the air flow (high-temperature and high-humidity air flow) discharged from the air outlet hole 191 can be reduced from scalding or blistering the cabinet, thereby reducing the damage to the cabinet.

[0062] It should be understood that the heat dissipation air duct is formed by the component structure necessary for realizing the cooking requirements inside the body 10, rather than being formed by separately arranging components for forming the air duct structure. It can be a solid air duct structure or a path of air flow.

[0063] In addition, the air inlet hole 1321 is opened on the body 10, and the opening position of the air inlet hole 1321 can be the front side, rear side, top side, left side or right side of the body 10, etc. For example, when the air inlet hole 1321 is opened on the rear side of the body 10, under the operation of the fan assembly 18, the air flow enters through the rear side of the body 10 and exits through the front side of the body 10. With this setting, the influence between the inlet air flow and the outlet air flow can be reduced (such as the situation where the outlet air flow returns to the heat dissipation air duct through the air inlet hole 1321, resulting in a poor heat exchange effect), and the heat dissipation effect of the body 10 is effectively improved.

[0064] In this application, when the cooking appliance 100 cooks food, the fan assembly 18 operates, so that the outside air enters the heat dissipation air duct through the air inlet hole 1321. The air flow entering the heat dissipation air duct exchanges heat with the heat-generating positions inside the body 10, and the heat-exchanged air flow is discharged through the air outlet hole 191. The air outlet hole 191 is surrounded by the air guiding structure 111 of the outer cover 11 and the cavity assembly 13, and the heat dissipation air duct is formed by using the own structure of the body 10, thereby reducing the number of components of the cooking appliance 100, simplifying the assembly process during the assembly process of the cooking appliance 100, and further improving the assembly efficiency, so that the manufacturing cost of the cooking appliance 100 can be reduced.

[0065] It should be understood that in this application, the fan assembly 18 is arranged in the heat dissipation air duct. When the fan assembly 18 operates, a negative pressure is formed on the side of the fan assembly 18 facing the air inlet hole 1321, so that the external air flow is sucked into the heat dissipation air duct through the air inlet hole 1321 under the action of the negative pressure. A positive pressure is formed on the side of the fan assembly 18 facing the air outlet hole 191, so that the air flow in the heat dissipation air duct is discharged to the outside through the air outlet hole 191 under the action of the positive pressure to realize the flow of the air flow in the heat dissipation air duct.

[0066] It should be noted that in the present application, the fan assembly 18 includes a fan body and a mounting member (such as a mounting bracket, etc.). The mounting member is fixed (the fixing methods include but are not limited to snap connection, bonding, or connection by fasteners, etc.) in the heat dissipation air duct, and the fan body is mounted on the mounting member (the mounting methods include but are not limited to snap connection, bonding, or connection by fasteners, etc.).

[0067] In addition, the fan body can be a fan structure or a cross-flow fan structure with a volute, etc.

[0068] In some embodiments of the present invention, as Figure 2 and Figure 3 shown, the body 10 includes an outer cover 11 and a cavity assembly 13. Among them, the outer cover 11 covers the outside of the cavity assembly 13 and is connected to the cavity assembly 13. A part of the outer cover 11 is spaced from a part of the outer surface of the cavity assembly 13. The cooking cavity 17 is formed by enclosing the cavity assembly 13, and the first chamber 15 and the second chamber 16 are formed by enclosing the outer cover 11 and a part of the outer surface of the cavity assembly 13.

[0069] It should be understood that a part of the outer cover 11 is spaced from a part of the outer surface of the cavity assembly 13. By using the outer cover 11 and the cavity assembly 13 to enclose a space to provide the space required for mounting the components of the body 10 (i.e., functional components, such as a heating assembly and a control assembly, etc.). At this time, the space enclosed by the outer cover 11 and the cavity assembly 13 forms the first chamber 15 and the second chamber 16, and there is no need to provide a separate component (such as a wind guide cover structure, etc.) for the heat dissipation air duct, thereby reducing the number of components of the cooking appliance 100, simplifying the assembly process during the assembly process of the cooking appliance 100, and further improving the assembly efficiency, so that the manufacturing cost of the cooking appliance 100 can be reduced.

[0070] In some embodiments of the present invention, as Figure 3 shown, the body 10 further includes a first chamber 15 and a second chamber 16 that are interconnected. The first chamber 15 and the second chamber 16 are respectively arranged outside the cooking cavity 17. Along the length direction X of the body 10, the first cavity is located on one side of the cooking cavity 17 and constitutes part of the heat dissipation air duct, and the second chamber 16 is located on the other side of the cooking cavity 17 and constitutes part of the heat dissipation air duct.

[0071] The first chamber 15 is in communication with the air inlet hole 1321, and the second chamber 16 is in communication with the air outlet hole 191. The fan assembly 18 can be arranged in the first chamber 15 or in the second chamber 16. For example, when the fan assembly 18 is arranged in the first chamber 15, since the air inlet hole 1321 is in communication with the first chamber 15, when the fan assembly 18 operates, the negative pressure formed in the first chamber 15 can be made higher, thereby increasing the speed of the outside air flowing into the first chamber 15 through the air inlet hole 1321, improving the air intake of the heat dissipation air duct, and further enhancing the heat dissipation effect of the heat dissipation air duct.

[0072] Specifically, both the first chamber 15 and the second chamber 16 are formed by enclosing with the self-structure of the body 10, and both the first chamber 15 and the second chamber 16 are enclosed spaces. The first chamber 15 is in communication with the outside through the air inlet hole 1321, and the second chamber 16 is in communication with the outside through the air outlet hole 191. Among them, both the first chamber 15 and the second chamber 16 are three-dimensional space structures, which can provide installation space for the components of the body 10, such as the electric control components and heating components of the body 10, etc.

[0073] When the fan assembly 18 operates, the outside air flows into the first chamber 15 through the air inlet hole 1321 and flows in the first chamber 15. The process of the air flowing in the first chamber 15 can exchange heat with the components arranged in the first chamber 15 to reduce the temperature rise of the components arranged in the first chamber 15. The air passing through the first chamber 15 enters the second chamber 16, and the air entering the second chamber 16 can also cool the components arranged in the second chamber 16. After the heat exchange in the second chamber 16, the air is discharged through the air outlet hole 191.

[0074] In this application, as Figure 3 shown, along the length direction X, the first chamber 15 and the second chamber 16 are respectively arranged on the opposite sides of the cooking chamber 17, and the first chamber 15 and the second chamber 16 are used to communicate to form a heat dissipation air duct, so that the heat dissipation air duct can be formed by using the structure inside the body 10, enabling the air to flow inside the body 10 to meet the heat exchange requirements of the body 10, and further reducing the temperature rise of the body 10, thereby reducing the failure rate of the body 10.

[0075] It should be understood that in this application, along the length direction X of the body 10, the first chamber 15 and the second chamber 16 are respectively arranged on the opposite sides of the cooking chamber 17.

[0076] Among them, the first chamber 15 can be arranged adjacent to the cooking chamber 17 (i.e., there is no spacing space 30 between the two, for example, separated by a plate-like structure), or the first chamber 15 can be arranged spaced apart from the cooking chamber 17 (i.e., there is a spacing space 30 between the two). For example, the first chamber 15 can be arranged adjacent to the cooking chamber 17. With such an arrangement, the size of the body 10 can be reduced in the length direction X. At the same time, when the air flow passes through the first chamber 15, the outer surface of the cooking chamber 17 facing the first chamber 15 can also be cooled to reduce the temperature rise of the outer surface of the cooking chamber 17 facing the first chamber 15.

[0077] The second chamber 16 can be arranged adjacent to the cooking chamber 17 (i.e., there is no spacing space 30 between the two, for example, separated by a plate-like structure), or the second chamber 16 can be arranged spaced apart from the cooking chamber 17 (i.e., there is a spacing space 30 between the two). For example, the second chamber 16 can be arranged adjacent to the cooking chamber 17. With such an arrangement, the size of the body 10 can be reduced in the length direction X. At the same time, when the air flow passes through the second chamber 16, the outer surface of the cooking chamber 17 facing the second chamber 16 can also be cooled to reduce the temperature rise of the outer surface of the cooking chamber 17 facing the second chamber 16.

[0078] In some embodiments of the present invention, as Figure 3 shown, the body 10 is respectively provided with a first chamber 15 and a second chamber 16 in its length direction X, and the first chamber 15 and the second chamber 16 are respectively located on opposite sides of the cooking chamber 17. The air inlet hole 1321 is communicated with the first chamber 15, and the air outlet hole 191 is communicated with the second chamber 16.

[0079] The cooking chamber 17 includes a plurality of side walls, and the plurality of side walls are connected to enclose the cooking chamber 17. Among them, two adjacent side walls are arranged at an angle.

[0080] An air inlet hole 1333 and an exhaust hole 1334 are respectively opened on the side walls of the cooking chamber 17, and the exhaust hole 1334 and the air inlet hole 1333 are arranged on two different side walls. The cooking chamber 17 is communicated with the first chamber 15 of the body 10 through the air inlet hole 1333, and the cooking chamber 17 is communicated with the second chamber 16 of the body 10 through the exhaust hole 1334. The first chamber 15, the cooking chamber 17, and the second chamber 16 are sequentially communicated, and the three form a heat dissipation air duct.

[0081] As Figure 3As shown, when the fan assembly 18 is operating, outside air flows into the first chamber 15 through the air inlet hole 1321 and flows within the first chamber 15. During the process of the air flowing within the first chamber 15, heat exchange can be performed on the components disposed within the first chamber 15 to reduce the temperature rise of the components disposed within the first chamber 15. The air flow in the first chamber 15 reaches the second chamber 16 through the air inlet hole 1333 and flows towards the exhaust hole 1334 within the cooking chamber 17. The air flow within the cooking chamber 17 enters the second chamber 16 through the exhaust hole 1334. The air flow entering the second chamber 16 can also cool the components disposed within the second chamber 16. After the heat exchange within the second chamber 16, the air flow is discharged through the air outlet hole 191.

[0082] After the air flow flowing out of the first chamber 15 through the air inlet hole 1333 enters the cooking chamber 17, it can be mixed with the air flow within the cooking chamber 17, and the mixed air flow flows out to the second chamber 16 through the exhaust hole 1334. Among them, steam is generated during the cooking process in the cooking chamber 17. By introducing the air flow in the first chamber 15 into the cooking chamber 17, mixing it with the air flow within the cooking chamber 17, and then discharging it through the exhaust hole 1334, the influence of the steam on the cooking process can be reduced, so that the cooking quality of the food can be improved.

[0083] In addition, when the fan assembly 18 is operating, outside air enters the first chamber 15 through the air inlet hole 1321. The air flow within the first chamber 15 is introduced into the cooking chamber 17 through the air inlet hole 1333. The air flow within the cooking chamber 17 is introduced into the second chamber 16 through the exhaust hole 1334. The air flow within the second chamber 16 is discharged through the air outlet hole 191. By using the flowing air flow to drain the steam generated during the cooking process within the cooking chamber 17, the discharge efficiency of the steam can be improved, so that the cooking quality of the food can be further improved.

[0084] At the same time, by using the air flow to draw out the steam within the cooking chamber 17, the adverse effects on the user caused by the steam when the user opens the cooking chamber 17 are reduced (such as the situation of being scalded due to the high temperature of the steam). The generation of condensed water within the cooking chamber 17 is also reduced, thereby reducing the food safety problems caused by the breeding of bacteria due to the presence of condensed water within the cooking chamber 17.

[0085] It should be understood that in order to reduce the adverse effects of the steam on the electrical components of the machine body 10, when arranging the components of the machine body 10 within the second chamber 16, the components are usually not electrical components.

[0086] It should be noted that the air inlet hole 1333 and the air outlet hole 1334 are respectively formed on different side walls of the cooking cavity 17. Among them, the air inlet hole 1333 and the air outlet hole 1334 can be respectively formed on two adjacent side walls of the cooking cavity 17, or the air inlet hole 1333 and the air outlet hole 1334 can be respectively formed on two spaced side walls of the cooking cavity 17.

[0087] For example, as Figure 2 、 Figure 4 and Figure 5 shown, in the length direction X of the body 10, the cooking cavity 17 includes two opposite side walls. One of the two side walls is adjacent to the first chamber 15, and the other side wall is adjacent to the second chamber 16. Among them, the air inlet hole 1333 is formed on the side wall adjacent to the first chamber 15, and the air outlet hole 1334 is formed on the side wall adjacent to the second chamber 16. With such a setting, the path of the air flow in the cooking cavity 17 can be increased, and the contact area with the steam in the cooking cavity 17 can be increased, thereby improving the discharge effect of the steam in the cooking cavity 17.

[0088] In some embodiments of the present invention, as Figure 3 shown, in the length direction X of the body 10, the cooking cavity 17 includes two opposite side walls. One of the two side walls is adjacent to the first chamber 15, and the other side wall is adjacent to the second chamber 16. Among them, the air inlet hole 1333 is formed on the side wall adjacent to the first chamber 15, so that the cooking cavity 17 is communicated with the first chamber 15 through the air inlet hole 1333, and the air outlet hole 1334 is formed on the side wall adjacent to the second chamber 16, so that the cooking cavity 17 is communicated with the second chamber 16 through the air inlet hole 1333.

[0089] Specifically, a pick-up and placement opening is provided on the front end face of the body 10, and the cooking cavity 17 is communicated with the outside through the pick-up and placement opening. In the width direction Y of the body 10, there is a first distance between the pick-up and placement opening and the air inlet hole 1333, and the first distance is the minimum distance between the pick-up and placement opening and the air inlet hole 1333. In the width direction Y of the body 10, there is a second distance between the pick-up and placement opening and the air outlet hole 1334, and the second distance is the minimum distance between the pick-up and placement opening and the air outlet hole 1334. The first distance is set to be less than the second distance, so that the air inlet hole 1333 is arranged farther away from the pick-up and placement opening than the air inlet hole 1333.

[0090] During the cooking process of the cooking appliance 100, the cooking cavity 17 is in a high-temperature state (higher than the external ambient temperature and reaching the temperature required for food cooking). The air flow flowing into the cooking cavity 17 from the first chamber 15 through the air inlet hole 1333 is mixed with the high-temperature steam in the cooking cavity 17, and the mixed air flow is discharged to the second chamber 16 through the exhaust hole 1334 and then discharged through the second chamber 16. The mixed air flow in the cooking cavity 17 is mixed with high-temperature steam, making the position where the exhaust hole 1334 is located at a relatively high temperature. The first distance is set to be less than the second distance, so that the air inlet hole 1333 is set farther away from the access opening compared to the air inlet hole 1333, thereby reducing the temperature rise at the access opening position, and further being able to reduce the adverse effects on the user caused by high temperature (such as scalding the user, etc.).

[0091] In addition, as Figure 5 shown, in the width direction Y of the body 10, there is a first distance between the access opening and the air inlet hole 1333, and a second distance between the access opening and the exhaust hole 1334. The first distance is set to be less than the second distance, so that the air inlet hole 1333 is set farther away from the access opening compared to the air inlet hole 1333. With such a setting, the distance between the air inlet hole 1333 and the exhaust hole 1334 can be increased, the flow path of the air flow in the cooking cavity 17 can be further increased, and the contact area with the steam in the cooking cavity 17 is also further increased, thereby further improving the discharge effect of the steam in the cooking cavity 17.

[0092] It should be noted that the exhaust hole 1334 has a projection on the side wall where the air inlet hole 1333 is located. Along the width direction Y of the body 10, there is an interval between the projection and the air inlet hole 1333, or they can be partially overlapped. For example, there is an interval between the projection and the air inlet hole 1333. With such a setting, the distance between the air inlet hole 1333 and the exhaust hole 1334 can be further increased, thereby further increasing the flow path of the air flow in the cooking cavity 17, and also further increasing the contact area with the steam in the cooking cavity 17, thereby further improving the discharge effect of the steam in the cooking cavity 17.

[0093] In some embodiments of the present invention, in the length direction X of the body 10, the cooking cavity 17 includes two oppositely arranged side walls. One of the two side walls is adjacent to the first chamber 15, and the other side wall is adjacent to the second chamber 16. Among them, the air inlet hole 1333 is opened on the side wall adjacent to the first chamber 15, so that the cooking cavity 17 is communicated with the first chamber 15 through the air inlet hole 1333, and the exhaust hole 1334 is opened on the side wall adjacent to the second chamber 16, so that the cooking cavity 17 is communicated with the second chamber 16 through the air inlet hole 1333.

[0094] Specifically, the cooking cavity 17 includes a bottom wall and a top wall, which are oppositely arranged in the height direction Z of the body 10 (the bottom wall is arranged below the top wall), and the bottom wall and the top wall are respectively connected to the side wall where the air inlet hole 1333 is located. Among them, the distance between the top wall and the air inlet hole 1333 is less than the distance between the bottom wall and the air inlet hole 1333.

[0095] During the cooking process, the steam generated during the cooking process is likely to float in the upper space of the cooking cavity 17. By setting the distance between the top wall and the air inlet hole 1333 to be less than the distance between the bottom wall and the air inlet hole 1333, the air inlet hole 1333 is arranged closer to the top wall of the cooking cavity 17, so that the air flow can quickly mix with the steam after flowing into the cooking cavity 17 through the air inlet hole 1333, thereby increasing the contact opportunity with the steam and improving the steam discharge effect.

[0096] In some embodiments of the present invention, as Figure 3 shown, in the length direction X of the body 10, the cooking cavity 17 includes two oppositely arranged side walls. One of the two side walls is adjacent to the first chamber 15, and the other side wall is adjacent to the second chamber 16. Among them, the air inlet hole 1333 is opened on the side wall adjacent to the first chamber 15, so that the cooking cavity 17 is communicated with the first chamber 15 through the air inlet hole 1333, and the exhaust hole 1334 is opened on the side wall adjacent to the second chamber 16, so that the cooking cavity 17 is communicated with the second chamber 16 through the air inlet hole 1333.

[0097] Specifically, the cooking cavity 17 includes a bottom wall and a top wall, which are oppositely arranged in the height direction Z of the body 10 (the bottom wall is arranged below the top wall), and the bottom wall and the top wall are respectively connected to the side wall where the air inlet hole 1333 is located. The distance between the top wall and the exhaust hole 1334 is less than the distance between the bottom wall and the exhaust hole 1334.

[0098] During the cooking process, the steam generated during the cooking process is likely to float in the upper space of the cooking cavity 17. By setting the distance between the top wall and the exhaust hole 1334 to be less than the distance between the bottom wall and the exhaust hole 1334, the exhaust hole 1334 is arranged closer to the top wall of the cooking cavity 17, so that the air flow mixed with steam in the cooking cavity 17 can be quickly discharged to the second chamber 16 through the exhaust hole 1334 and discharged to the outside of the body 10 through the air outlet hole 191, thereby further increasing the contact opportunity with the steam and further improving the steam discharge effect.

[0099] It should be noted that, along the height direction Z of the body 10, the height where the air inlet hole 1333 is located (the minimum distance between the air inlet hole 1333 and the bottom wall) and the height where the air outlet hole 1334 is located (the minimum distance between the air outlet hole 1334 and the bottom wall) are the same or different. For example, the height where the air inlet hole 1333 is located is less than the height where the air outlet hole 1334 is located. With such a setting, the distance between the air inlet hole 1333 and the air outlet hole 1334 can be further increased, thereby further increasing the flow path of the air flow in the cooking cavity 17 and further increasing the contact area with the steam in the cooking cavity 17, thus further improving the discharge effect of the steam in the cooking cavity 17.

[0100] In some embodiments of the present invention, as Figure 3 shown, in the length direction X of the body 10, the cooking cavity 17 includes two oppositely arranged side walls. One of the two side walls is adjacent to the first chamber 15, and the other side wall is adjacent to the second chamber 16. Among them, the air inlet hole 1333 is opened on the side wall adjacent to the first chamber 15, so that the cooking cavity 17 is communicated with the first chamber 15 through the air inlet hole 1333, and the air outlet hole 1334 is opened on the side wall adjacent to the second chamber 16, so that the cooking cavity 17 is communicated with the second chamber 16 through the air inlet hole 1333.

[0101] Specifically, the body 10 includes a heating component. When the heating component operates, it can provide heat in the cooking cavity 17, so that the food in the cooking cavity 17 reaches the cooking temperature, thereby realizing the cooking of the food.

[0102] Among them, the heating component can be at least one of a thermal radiation heating component, a hot air component, a steam component, and a microwave generating component.

[0103] It should be noted that the air inlet hole 1333 can be an open structure (i.e., there is no obstruction at the opening position), a mesh structure (i.e., a plurality of holes with smaller apertures are opened in a certain area), or a shutter structure (a plurality of guide plates are arranged at the opening position to form a shutter structure).

[0104] In the present application, as Figure 5 shown, the air inlet hole 1333 is set as the first mesh, so as to reduce foreign objects from entering the cooking cavity 17 through the first chamber 15 on the basis of satisfying the connection between the first chamber 15 and the cooking cavity 17, thereby improving the hygiene level in the cooking cavity 17.

[0105] In addition, the aperture of the first mesh is less than one quarter of the wavelength of the microwave. With such a setting, when the heating component includes a microwave generating component, the first mesh can be used to shield the microwave, reducing the leakage of the microwave through the position of the air inlet hole 1333, and improving the safety performance of the body 10.

[0106] In some embodiments of the present invention, as shown in FIG. 3, in the length direction X of the body 10, the cooking cavity 17 includes two oppositely arranged side walls. One of the two side walls is adjacent to the first chamber 15, and the other side wall is adjacent to the second chamber 16. Among them, the air inlet hole 1333 is opened on the side wall adjacent to the first chamber 15, so that the cooking cavity 17 is communicated with the first chamber 15 through the air inlet hole 1333, and the exhaust hole 1334 is opened on the side wall adjacent to the second chamber 16, so that the cooking cavity 17 is communicated with the second chamber 16 through the air inlet hole 1333.

[0107] Specifically, the body 10 includes a heating assembly. When the heating assembly operates, it can provide heat in the cooking cavity 17, so that the food in the cooking cavity 17 reaches the cooking temperature, thereby realizing the cooking of the food.

[0108] Among them, the heating assembly can be at least one of a thermal radiation heating assembly, a hot air assembly, a steam assembly, and a microwave generating assembly.

[0109] It should be noted that the exhaust hole 1334 can be an open structure (that is, there is no obstruction at the opening position), a mesh structure (that is, a plurality of holes with smaller apertures are opened in a certain area), or a louver structure (a plurality of flow guiding plates are arranged at the opening position to form a louver structure).

[0110] In the present application, as Figure 5 shown, the exhaust hole 1334 is set as a second mesh hole, so that on the basis of satisfying the connection between the second chamber 16 and the cooking cavity 17, foreign objects entering the cooking cavity 17 through the second chamber 16 can be reduced, thereby improving the hygiene level in the cooking cavity 17.

[0111] In addition, the aperture of the second mesh hole is less than one-fourth of the wavelength of the microwave. With such a setting, when the heating assembly includes a microwave generating assembly, the second mesh hole can be used to shield the microwave, reducing the leakage of the microwave through the position of the exhaust hole 1334, and improving the safety performance of the body 10.

[0112] In some embodiments of the present invention, a third chamber 19 is also surrounded by a part of the outer surface of the outer cover 11 and the cavity assembly 13. Along the height direction Z of the body 10, the third chamber 19 is arranged above the cooking cavity 17. The air outlet hole 191 is located above the cooking cavity 17 and is communicated with the third chamber 19, and the second chamber 16 is communicated with the third chamber 19.

[0113] By arranging both the third chamber 19 and the air outlet 191 above the cooking chamber 17, the top exhaust of the cooking appliance 100 is realized. The top exhaust of the cooking appliance 100 (the exhausted air flow is a hot air flow, and the hot air flow has a certain lifting force. By arranging the air outlet 191 and the third chamber 19 above the cooking chamber 17, the exhausted air flow will not come into secondary contact with the cooking appliance 100 when rising), reducing the influence of the exhausted air flow on other positions of the cooking appliance 100 (for example, the situation where the exhausted air flow blows onto the cooking appliance and causes the temperature rise of the cooking appliance 100 at that time).

[0114] In addition, along the length direction of the body 10, the first chamber 15 and the second chamber 16 are arranged on opposite sides of the cooking chamber 17. Along the height direction Z of the body 10, the third chamber 19 is arranged above the cooking chamber 17. The first chamber 15, the cooking chamber 17, the second chamber 16 and the third chamber 19 are communicated in sequence, thereby forming a heat dissipation air duct. The heat dissipation air duct covers the circumference outside the cooking chamber 17, so as to reduce the transfer of the heat of the cooking chamber 17 to the outside, and further reduce the temperature rise of the outer cover 11, reducing the situation of scalding the cabinet and the user due to the temperature rise of the outer cover 11.

[0115] In some embodiments of the present invention, as Figure 2 or Figure 4 shown, the cavity assembly 13 includes a first plate body 131, a second plate body 132 and a side enclosure plate 133. Along the width direction Y of the body 10, the first plate body 131 and the second plate body 132 are arranged at intervals, and the first plate body 131 and the second plate body 132 are parallel to each other. Among them, the first plate body 131 is located on the front side of the second plate body 132 (i.e., the front side of the body 10), the air outlet 191 and the access opening are respectively opened on the first plate body 131, and along the height direction Z of the body 10, the air outlet 191 is located above the access opening.

[0116] The side enclosure plate 133 is arranged between the first plate body 131 and the second plate body 132. The side enclosure plate 133 is a cylindrical structure, and openings are respectively provided at both ends of the cylindrical structure (both ends along the length direction X of the body 10). Among them, one end of the cylindrical structure facing the second plate body 132 is connected to the second plate body 132 (the connection methods include but are not limited to snap connection, welding or connection through a connecting piece, etc.), and the opening on this side is closed by the second plate body 132. One end of the cylindrical structure facing the first plate body 131 is connected to the first plate body 131 (the connection methods include but are not limited to snap connection, welding or connection through a connecting piece, etc.), and the opening on this side is communicated with the access opening, and the shapes and sizes of the opening of the cylindrical structure and the access opening are the same.

[0117] The structure where the cylindrical structure, the first plate body 131, and the second plate body 132 enclose the cooking cavity 17. Outside the cooking cavity 17, the first plate body 131 and the second plate body 132 respectively protrude from the side enclosing plate 133. The protruding parts of the first plate body 131 and the second plate body 132 relative to the side plate are respectively connected to the outer cover 11 (the connection methods include but are not limited to snap connection, welding, or connection through connectors, etc.). The space enclosed by the outer cover 11, the first plate body 131, the second plate body 132, and the side enclosing plate 133 constitutes the structure of the first chamber 15 and the second chamber 16.

[0118] Using the cavity assembly 13 to enclose the cooking cavity 17, and using the cavity assembly 13 and the outer cover 11 to enclose the first chamber 15 and the second chamber 16, the overall structure is simple, which can effectively reduce the number of components of the body 10, thus facilitating the assembly during the production process, effectively improving the assembly efficiency, and further reducing the manufacturing cost.

[0119] It should be understood that in this application, the first plate body 131 is a flat plate structure, and the second plate body 132 can be a flat plate structure or a non - flat plate structure.

[0120] It should be pointed out that the side enclosing plate 133 with a cylindrical structure has a quadrilateral longitudinal section (the plane parallel to the first plate body 131). The side enclosing plate 133 can be an integral structure or a split structure.

[0121] For example, as Figure 2 and Figure 5 shown, the side enclosing plate 133 is a split structure, including a U - shaped plate 1331 and a top plate 1332. The top plate 1332 is connected to the U - shaped plate 1331 (the connection methods include but are not limited to snap connection, welding, or connection through connectors, etc.), and closes the top opening of the U - shaped plate 1331, thus forming a cylindrical structure. Setting the side enclosing plate 133 as a split structure improves the processing convenience.

[0122] In some embodiments of the present invention, as Figure 3As shown, the cavity assembly 13 includes a first plate body 131, a second plate body 132, and a side enclosure plate 133. Along the width direction Y of the machine body 10, the first plate body 131 and the second plate body 132 are spaced apart and parallel to each other. Among them, the first plate body 131 is located on the front side of the second plate body 132 (i.e., the front side of the machine body 10). The air outlet hole 191 and the access opening are respectively formed on the first plate body 131. And along the length direction X of the machine body 10, the air outlet hole 191 is located on one side of the access opening. The side enclosure plate 133 is arranged between the first plate body 131 and the second plate body 132. The side enclosure plate 133 is of a cylindrical structure, and openings are respectively provided at both ends of the cylindrical structure (both ends along the length direction X of the machine body 10). Among them, the end of the cylindrical structure facing the second plate body 132 is connected to the second plate body 132, and the opening on this side is closed by the second plate body 132. The end of the cylindrical structure facing the first plate body 131 is connected to the first plate body 131, and the opening on this side is communicated with the access opening, and the shape and size of the opening of the cylindrical structure are the same as those of the access opening.

[0123] Specifically, on the outer side of the side enclosure plate 133 which is of a cylindrical structure, along the length direction X of the machine body 10, the part of the second plate body 132 located outside the side enclosure plate 133 includes a first part and a second part which are oppositely arranged. Among them, the first part encloses a part of the first chamber 15, and the second part encloses a part of the second chamber 16. The air inlet hole 1321 is formed on the first part.

[0124] By arranging the air inlet hole 1321 on the first part of the second plate body 132, when the machine body 10 is running, air can enter from the rear side of the machine body 10, and the air outlet hole 191 is located on the front side of the machine body 10 and discharges air towards the front end of the machine body 10. With such an arrangement, when the heat dissipation air duct dissipates heat, it realizes air intake from the rear side of the machine body 10 and air outlet from the front side, thereby reducing the interference between the intake air flow and the outlet air flow, and further improving the heat exchange effect on the machine body 10.

[0125] In addition, by forming the air inlet hole 1321 on the first part of the second plate body 132, air intake from the rear side of the machine body 10 is realized, and the air flow entering the first chamber 15 flows along the width direction Y of the machine body 10, reducing the turning of the air flow in the first chamber 15, ensuring the flow speed of the air flow, and thus improving the heat exchange efficiency of the air flow in the first chamber 15.

[0126] It should be understood that, on the outer side of the side wall panel 133 of the cylindrical structure, setting the second plate body 132 to protrude relative to the side wall panel 133 enables the use of the protruding part of the second plate body 132 relative to the side wall panel 133 to connect with the outer cover 11, and enclose the first chamber 15 and the second chamber 16 with the outer cover 11. Thus, the structure of the cavity assembly 13 of the body 10 can be simplified, effectively reducing the manufacturing cost of the cavity assembly 13. In addition, the structure of the cavity assembly 13 is convenient for assembly, improving the assembly efficiency and further reducing the manufacturing cost.

[0127] It should be noted that the air inlet hole 1321 is opened on the first part of the second plate body 132, and the processing methods include but are not limited to stamping or drilling.

[0128] In some embodiments of the present invention, as Figure 3 shown, the body 10 is respectively provided with a first chamber 15 and a second chamber 16 in its length direction X, and the first chamber 15 and the second chamber 16 are respectively located on opposite sides of the cooking chamber 17. The air inlet hole 1321 is communicated with the first chamber 15, and the air outlet hole 191 is communicated with the second chamber 16.

[0129] Specifically, the fan assembly 18 is arranged in the first chamber 15, and the fan assembly 18 is arranged opposite to the air inlet hole 1321. There can be an interval or no interval between the fan assembly 18 and the air inlet hole 1321. For example, the fan assembly 18 is arranged without an interval from the air inlet hole 1321, that is, the fan assembly 18 leans against the part where the second plate body 132 protrudes from the side wall panel 133, and the inlet of the fan assembly 18 abuts against the air inlet hole 1321. When the fan assembly 18 operates, the external air flow directly enters the fan assembly 18 through the air inlet hole 1321 and enters the first chamber 15 through the fan assembly 18. With this setting, the rate of air flow entering the first chamber 15 can be increased.

[0130] As Figure 2 shown, a power device group 14 (such as an inverter, a magnetron, etc.) of the body 10 is also arranged in the first chamber 15. The power device group 14 is arranged between the fan assembly 18 and the air inlet hole 1333 of the cooking chamber 17. With this setting, when the fan operates, the air flow enters the first chamber 15 through the air inlet hole 1321 and first passes through the power device group 14, using the air flow to exchange heat with the power device group 14, reducing the temperature rise of the power device group 14, and thus reducing the failure rate of the power device group 14. And

[0131] The airflow after heat exchange of the power device group 14 enters the cooking cavity 17 through the air inlet hole 1333, mixes with the steam (or oil fumes generated during cooking, etc.) in the cooking cavity 17, and enters the second chamber 16 through the exhaust hole 1334 of the cooking cavity 17, and finally is discharged from the front side of the body 10 through the air outlet hole 191.

[0132] In some embodiments of the present invention, as Figure 3 shown, the body 10 includes an outer cover 11 and a cavity assembly 13. Among them, the outer cover 11 covers the outside of the cavity assembly 13 and is connected to the cavity assembly 13. A part of the outer cover 11 is spaced from a part of the outer surface of the cavity assembly 13. The cooking cavity 17 is formed by enclosing the cavity assembly 13, and the first chamber 15 and the second chamber 16 are formed by enclosing the outer cover 11 and a part of the outer surface of the cavity assembly 13. The cavity assembly 13 includes a first plate body 131, a second plate body 132, and a side enclosure plate 133. Along the width direction Y of the body 10, the first plate body 131 and the second plate body 132 are spaced apart, and the first plate body 131 and the second plate body 132 are parallel to each other. Among them, the first plate body 131 is located in front of the second plate body 132 (i.e., the front side of the body 10). The air outlet hole 191 and the access opening are respectively opened on the first plate body 131, and along the length direction X of the body 10, the air outlet hole 191 is located on one side of the access opening.

[0133] The side enclosure plate 133 is arranged between the first plate body 131 and the second plate body 132. The side enclosure plate 133 is a cylindrical structure, and both ends of the cylindrical structure (both ends along the length direction X of the body 10) are respectively provided with openings. Among them, one end of the cylindrical structure facing the second plate body 132 is connected to the second plate body 132, and the opening on this side is closed by the second plate body 132. One end of the cylindrical structure facing the first plate body 131 is connected to the first plate body 131, and the opening on this side is communicated with the access opening. The cylindrical structure, the first plate body 131, and the second plate body 132 enclose the structure of the cooking cavity 17.

[0134] Specifically, as Figure 1 、 Figure 2 and Figure 4 shown, the body 10 further includes a door body 12. The door body 12 is connected to the first plate body 131, and the door body 12 can perform an opening and closing action relative to the first plate body 131. The access opening on the first plate body 131 is opened or closed by the opening and closing of the door body 12, so as to realize the opening or closing operation of the cooking cavity 17.

[0135] Figure 6 ​As shown, the air guiding structure 111 is a convex structure formed by the outer cover 11 extending away from the cavity assembly 13. The convex structure and the cavity assembly 13 enclose an air outlet hole 191. By setting the position of the air outlet hole 191, there is no need to set up an independent air guiding cover or other structures for the derivation of the air flow, which reduces the number of components, simplifies the assembly procedure, improves the assembly efficiency, and reduces the manufacturing cost.

[0136] In some embodiments of the present application, the air guiding structure 11 which is a convex structure is a pressing formed on the outer cover 11.

[0137] Specifically, the air guiding structure 111 is a pressing formed by being recessed towards the side away from the cavity assembly 13, and the air guiding structure 111 communicates with a part of the edge of the outer cover 11, so that the air guiding structure 111 forms an aggregating structure on the outer cover 11. After the air flow in the heat dissipation air duct flows into the position of the air guiding structure 111, the air guiding structure 111 aggregates the air flow and discharges it uniformly, thereby increasing the flow rate of the air flow and improving the discharge efficiency of the air flow.

[0138] In addition, the air guiding structure 111 is formed by stamping. The shape of the cross-section of the air guiding structure (the plane perpendicular to the height direction of the machine body) can be semi-circular or polygonal (such as triangular, quadrilateral or trapezoidal, etc.). For example, the air guiding structure 111 is a rectangular structure (the cross-section is quadrilateral). The length of the rectangular structure (the dimension along the length direction of the machine body 10) is in the range of 100 - 440 mm (for example, it can be 100 mm, 130 mm, 160 mm, 190 mm, 210 mm, 230 mm, 260 mm, 290 mm, 310 mm, 340 mm, 370 mm, 410 mm, 440 mm), the width (the dimension along the width direction of the machine body 10) is in the range of 20 - 280 mm (for example, it can be 20 mm, 40 mm, 60 mm, 90 mm, 100 mm, 120 mm, 160 mm, 190 mm, 210 mm, 240 mm, 270 mm, 280 mm), and the height (the dimension along the height direction of the machine body 10) is in the range of 2 - 10 mm (for example, it can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm).

[0139] In some embodiments of the present application, the convex structure protrudes out of the door body 12, and the air flow discharged from the air outlet hole 191 is discharged above the door body 12.

[0140] By arranging both the third chamber 19 and the air outlet 191 above the cooking chamber 17, the top exhaust of the cooking appliance 100 is realized. The top exhaust of the cooking appliance 100 (the exhausted air flow is a hot air flow, and the hot air flow has a certain lifting force. By arranging the air outlet 191 and the third chamber 19 above the cooking chamber 17, the exhausted air flow will not come into secondary contact with the cooking appliance 100 when rising), reducing the influence of the exhausted air flow on other positions of the cooking appliance 100 (for example, the situation where the exhausted air flow blows onto the cooking appliance and causes the temperature rise of the cooking appliance 100 at that time).

[0141] It should be noted that the connection mode between the door body 12 and the first plate body 131 can be hinge connection or slide connection. For example, the door body 12 and the first plate body 131 are connected by a hinge, and the opening or closing operation of the access opening of the cooking chamber 17 is realized by the pivoting of the door body 12 relative to the first plate body 131. The door body 12 and the first plate body 131 are arranged to be pivotally connected, so as to facilitate the user to control the door body 12 during use and improve the convenience of the user during use.

[0142] In addition, the door body 12 includes a door frame and a door glass. The door frame is connected to the first plate body 131, and the door glass is embedded in the door frame. The door glass is a light-transmitting structure, and the condition inside the cooking chamber 17 can be observed through the door glass, so that the user can timely understand the cooking state of the food in the cooking chamber 17, improving the convenience of the user during use.

[0143] In addition, in order to reduce the temperature rise of the door body 12, a corresponding heat dissipation structure can be arranged in the door body 12, and the heat dissipation structure is used to reduce the temperature rise of the door body 12 to reduce the adverse impact on the user caused by the temperature rise of the door body 12. For example, a corresponding air duct can be arranged in the door body 12, the air duct is communicated with the outside, and an air flow driving component such as a small fan can be arranged in the air duct. The air flow driving component is used to realize the circulation of the air flow between the air duct and the outside, so as to reduce the temperature rise of the door body 12 and reduce the occurrence of the situation where the user is scalded due to the temperature rise of the door body 12. For another example, a corresponding cavity is arranged in the door body 12, and a phase change material (such as paraffin wax, etc.) is arranged in the cavity. The phase change material is used to absorb the heat transferred to the door body 12 to reduce the temperature rise of the door body 12 and reduce the occurrence of the situation where the user is scalded due to the temperature rise of the door body 12.

[0144] In some embodiments of the present invention, the body 10 of the cooking appliance 100 is embedded in the cabinet, and there is a large gap between the circumference of the body 10 and the inner wall of the cabinet, and the existence of the gap affects the coordination of the appearance of the cabinet.

[0145] In this application, as Figure 1 、 Figure 2 and Figure 4As shown, the cooking appliance 100 further includes an outer frame 20, which is connected to the body 10 and disposed around the circumference of the body 10. When the body 10 with the outer frame 20 is embedded in a cabinet, the outer frame 20 blocks the gap between the body 10 and the cabinet, thereby reducing the exposure of the gap and improving the appearance of the cabinet after the cooking appliance 100 is installed.

[0146] It should be noted that the outer frame 20 can be metal or non-metal. For example, the outer frame 20 can be plastic, which is low-cost and lightweight, reducing the weight of the cabinet. Furthermore, the outer frame 20 can be designed to match the color of the cabinet, further enhancing the overall consistency of the cabinet's appearance.

[0147] In addition, the connection methods between the outer frame 20 and the body 10 include but are not limited to snap connection, bonding, or connection via a connector.

[0148] like Figure 4 and Figure 6 As shown, in the present application, along the height c of the body 10, there is a partition space 30 between the outer frame 20 and the door body 12, and the air outlet 191 surrounded by the air guide structure 111 of the outer cover 11 and the cavity assembly 13 is arranged opposite to the partition space 30. The airflow discharged from the air outlet 191 can be discharged to the front side of the body 10 through the partition space 30 to achieve smooth discharge of the airflow.

[0149] By arranging the air outlet 191 to be opposite to the partition space 30 , a hidden design of the air outlet 191 is achieved, thereby improving the appearance coordination of the cooking appliance 100 .

[0150] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
