Description

Technical Field

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Built-in cooking appliances are installed inside cabinets. When cooking food, it is placed in the cooking chamber and heated. During cooking, the appliance needs to dissipate heat, and a built-in air duct guides the hot airflow to prevent it from negatively impacting the cabinetry.

[0004] Incorporating a draft hood into cooking appliances increases assembly complexity, reduces production efficiency, and raises manufacturing costs. Utility Model Content

[0050] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0051] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0052] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0053] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0054] like 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 embedding and installing in a cabinet. The body 10 is provided with a fan assembly 18, a heat dissipation duct, and a cooking cavity 17. The heat dissipation duct has an air outlet 191 and an air inlet 1321.

[0055] Specifically, a front opening is provided in the preset position of the cabinet, and 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 (also known as the front surface) can be flush with the opening of the embedded space, protrude relative to the opening of the embedded space, or be recessed relative to the opening of the embedded space.

[0056] In this application, the front end face of the body 10 is flush with the opening of the embedded space, so that the body 10 can be structurally supplemented at the embedded space after being embedded in the cabinet, reducing structural protrusions and improving the overall coordination and consistency of the cabinet.

[0057] like Figure 1As shown, when the unit 10 is embedded in the cabinet, and the user faces the unit 10, the side of the unit 10 facing the user is the front side, the side of the unit 10 away from the user is the rear side, the side of the unit 10 facing the ground is the bottom side, the side of the unit 10 away from the ground is the top side, the side of the unit 10 on the user's left is the left side, and the side of the unit 10 on the user's right is the right side. The left and right sides are arranged in the length direction (X) of the unit 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, such as 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 disposed in the heat dissipation duct. Driven by the fan assembly 18, external airflow enters the heat dissipation duct through the air inlet 1321, and the airflow in the heat dissipation duct can flow out to the outside through the air outlet 191.

[0059] The body 10 includes a cavity assembly 13 and an outer cover 11. The cavity assembly 13 encloses a cooking cavity 17. The outer cover 11 covers the outside of the cavity assembly 13. The outer cover 11 and a portion of the outer surface of the cavity assembly 13 enclose at least a portion of the heat dissipation air duct. A portion of the edge of the outer cover 11 forms an air guide structure 111. The air guide structure 111 and the cavity assembly enclose an air outlet 191. The cooking cavity 17 includes a loading and unloading port. The air outlet 191 faces the same direction as the loading and unloading port. The air outlet 191 is configured to vent air from the front of the body 10.

[0060] The loading and unloading port of the cooking cavity 17 is located on the front side of the body 10, allowing the user to place or remove food into or from the cooking cavity 17. The shape of the loading and unloading port includes, but is not limited to, rectangles, circles, ovals, or other shapes. The shape of the cooking cavity 17 includes, but is not limited to, rectangular spaces, circular spaces, or ellipsoidal spaces. Furthermore, the opening area of ​​the loading and unloading port can be the same as or different from the area of ​​the longitudinal cross-section (the surface parallel to the front face of the body 10) of the cooking cavity 17. For example, if the cooking cavity 17 is a rectangular space with a quadrilateral longitudinal cross-section, the loading and unloading port will also be quadrilateral. The shape of the loading and unloading port matches the shape of the longitudinal cross-section of the cooking cavity 17, and their surfaces are equal. This design facilitates the user's placement and removal of food from the cooking cavity 17, improving user convenience.

[0061] The loading and unloading port of the cooking cavity 17 is located on the front side of the unit 10, meaning the loading and unloading port faces forward. The air outlet 191 is also located on the front side of the unit 10, meaning the air outlet 191 also faces forward (i.e., the air outlet 191 is configured to vent air away from the cabinet). At this time, the orientation of the loading and unloading port is the same as the orientation of the air outlet 191. When the airflow in the heat dissipation duct is discharged through the air outlet 191, the airflow is discharged through the front side of the unit 10. By setting the airflow to be discharged forward, it is possible to reduce the risk of the airflow (high temperature and high humidity airflow) from the air outlet 191 scalding or soaking the cabinet, thereby reducing damage to the cabinet.

[0062] It should be understood that the heat dissipation duct is formed by the internal components of the unit 10 that are necessary to meet cooking requirements, and is not formed by separately setting up components to form the duct structure. It can be a solid duct structure or a path for airflow.

[0063] In addition, the air inlet 1321 is formed on the body 10, and the location of the air inlet 1321 can be the front, rear, top, left, or right side of the body 10. For example, when the air inlet 1321 is formed on the rear side of the body 10, under the operation of the fan assembly 18, the airflow enters through the rear side of the body 10 and exits through the front side of the body 10. This arrangement can reduce the influence between the intake airflow and the exhaust airflow (for example, the exhaust airflow flows back into the heat dissipation duct through the air inlet 1321, resulting in a deterioration of the heat exchange effect), thus effectively improving the heat dissipation effect of the body 10.

[0064] In this application, when the cooking appliance 100 is cooking food, the fan assembly 18 operates, allowing outside air to enter the heat dissipation duct through the air inlet 1321. The airflow entering the heat dissipation duct exchanges heat with the heating elements inside the body 10, and the heat-exchanged airflow is discharged through the air outlet 191. The air outlet 191 is surrounded by the air guide structure 111 of the outer cover 11 and the cavity assembly 13, and forms a heat dissipation duct using the structure of the body 10 itself. This reduces the number of parts in the cooking appliance 100, simplifies the assembly process, improves assembly efficiency, and reduces the manufacturing cost of the cooking appliance 100.

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

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

[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 this utility model, such as Figure 2 and Figure 3 As shown, the body 10 includes an outer cover 11 and a cavity assembly 13. The outer cover 11 covers the outside of the cavity assembly 13 and is connected to the cavity assembly 13. A portion of the outer cover 11 is spaced apart from a portion of the outer surface of the cavity assembly 13. The cooking cavity 17 is formed by the cavity assembly 13. The first chamber 15 and the second chamber 16 are formed by the outer cover 11 and a portion of the outer surface of the cavity assembly 13.

[0069] It should be understood that a portion of the outer cover 11 is spaced apart from a portion of the outer surface of the cavity assembly 13. The space enclosed by the outer cover 11 and the cavity assembly 13 provides the space required for the installation of the components of the body 10 (i.e., functional components, such as heating components and control components). In this case, the space enclosed by the outer cover 11 and the cavity assembly 13 forms the first chamber 15 and the second chamber 16. There is no need to set up separate components (such as air guides) for the heat dissipation duct, thereby reducing the number of components of the cooking appliance 100. This simplifies the assembly process during the assembly of the cooking appliance 100, thereby improving the assembly efficiency and reducing the manufacturing cost of the cooking appliance 100.

[0070] In some embodiments of this utility model, such as Figure 3 As shown, the body 10 also includes a first chamber 15 and a second chamber 16 that are interconnected, and the first chamber 15 and the second chamber 16 are respectively located on the outside of the cooking cavity 17. Along the length direction X of the body 10, the first chamber is located on one side of the cooking cavity 17 and forms part of the heat dissipation duct, and the second chamber 16 is located on the other side of the cooking cavity 17 and forms part of the heat dissipation duct.

[0071] The first chamber 15 is connected to the air inlet 1321, and the second chamber 16 is connected to the air outlet 191. The fan assembly 18 can be located in either the first chamber 15 or the second chamber 16. For example, if the fan assembly 18 is located in the first chamber 15, since the air inlet 1321 is connected to the first chamber 15, when the fan assembly 18 is running, the negative pressure formed in the first chamber 15 will be higher, thereby increasing the speed at which the external airflow enters the first chamber 15 through the air inlet 1321, thus increasing the airflow volume of the heat dissipation duct and improving the heat dissipation effect of the heat dissipation duct.

[0072] Specifically, both the first chamber 15 and the second chamber 16 are enclosed by the structure of the body 10 itself, and both are closed spaces. The first chamber 15 is connected to the outside through the air inlet 1321, and the second chamber 16 is connected to the outside through the air outlet 191. Both the first chamber 15 and the second chamber 16 are three-dimensional spatial structures, providing installation space for components of the body 10, such as the electronic control components and heating components.

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

[0074] In this application, as Figure 3 As shown, along the length direction X, a first chamber 15 and a second chamber 16 are respectively arranged on opposite sides of the cooking cavity 17, and the first chamber 15 and the second chamber 16 are connected to form a heat dissipation air duct. This allows the structure inside the body 10 to form a heat dissipation air duct, so that airflow can flow inside the body 10 to meet the heat exchange requirements of the body 10, thereby reducing the temperature rise of the body 10 and 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 located on opposite sides of the cooking chamber 17.

[0076] The first chamber 15 can be arranged adjacent to the cooking chamber 17 (i.e., without a gap 30, 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 gap 30 between them). For example, the first chamber 15 can be arranged adjacent to the cooking chamber 17. This arrangement can reduce the size of the body 10 in the length direction X. At the same time, when the airflow flows through the first chamber 15, it can also dissipate heat from the outer surface of the cooking chamber 17 facing the first chamber 15, thereby reducing 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., without a gap 30, 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 gap 30 between them). For example, the second chamber 16 can be arranged adjacent to the cooking chamber 17. This arrangement can reduce the size of the body 10 in the length direction X. At the same time, when the airflow flows through the second chamber 16, it can also dissipate heat from the outer surface of the cooking chamber 17 facing the second chamber 16, thereby reducing the temperature rise of the outer surface of the cooking chamber 17 facing the second chamber 16.

[0078] In some embodiments of this utility model, such as Figure 3 As shown, the body 10 has a first chamber 15 and a second chamber 16 respectively in its length direction X, and the first chamber 15 and the second chamber 16 are located on opposite sides of the cooking cavity 17. The air inlet 1321 is connected to the first chamber 15, and the air outlet 191 is connected to the second chamber 16.

[0079] The cooking cavity 17 includes multiple sidewalls that are connected and surround the cooking cavity 17, wherein two connected sidewalls are set at an angle.

[0080] An air inlet 1333 and an exhaust 1334 are respectively provided on the side wall of the cooking cavity 17, and the exhaust 1334 and the air inlet 1333 are located on two different side walls. The cooking cavity 17 is connected to the first chamber 15 of the body 10 through the air inlet 1333, and the cooking cavity 17 is connected to the second chamber 16 of the body 10 through the exhaust 1334. The first chamber 15, the cooking cavity 17, and the second chamber 16 are connected in sequence, and the three form a heat dissipation duct.

[0081] like Figure 3As shown, when the fan assembly 18 is running, the outside airflow enters the first chamber 15 through the air inlet 1321 and flows within the first chamber 15. The airflow flowing within the first chamber 15 can exchange heat with the components installed in the first chamber 15, thereby reducing the temperature rise of the components installed in the first chamber 15. The airflow in the first chamber 15 flows through the air inlet 1333 into the second chamber 16 and then flows through the cooking chamber 17 to the exhaust port 1334. The airflow in the cooking chamber 17 enters the second chamber 16 through the exhaust port 1334. The airflow entering the second chamber 16 can also cool the components installed in the second chamber 16. After the heat exchange in the second chamber 16 is completed, the airflow is discharged through the air outlet 191.

[0082] The airflow from the first chamber 15 through the air inlet 1333 flows into the cooking chamber 17 and mixes with the airflow inside the cooking chamber 17. The mixed airflow then flows out through the exhaust 1334 to the second chamber 16. During cooking, the cooking chamber 17 generates steam, which draws the airflow from the first chamber 15 into the cooking chamber 17, mixes with the existing airflow, and is then exhausted through the exhaust 1334. This reduces the impact of steam on the cooking process, thereby improving the quality of the cooked food.

[0083] In addition, when the fan assembly 18 is running, outside air enters the first chamber 15 through the air inlet 1321. The airflow in the first chamber 15 is introduced into the cooking chamber 17 through the air inlet 1333. The airflow in the cooking chamber 17 is introduced into the second chamber 16 through the exhaust port 1334. The airflow in the second chamber 16 is discharged through the air outlet 191. The flowing airflow guides the steam generated in the cooking chamber 17 during the cooking process, thereby improving the steam discharge efficiency and further enhancing the cooking quality of the food.

[0084] At the same time, the airflow draws steam out of the cooking cavity 17, reducing the adverse effects of steam on users when the cooking cavity 17 is opened (such as burns caused by high steam temperature). It also reduces the generation of condensation in the cooking cavity 17, thereby reducing food safety issues caused by bacteria growth due to condensation in the cooking cavity 17.

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

[0086] It should be noted that the air inlet 1333 and the exhaust 1334 are respectively opened on different side walls of the cooking cavity 17. The air inlet 1333 and the exhaust 1334 can be opened on two adjacent side walls of the cooking cavity 17, or they can be opened on two spaced side walls of the cooking cavity 17.

[0087] For example, such as Figure 2 , Figure 4 and Figure 5 As shown, along the length X of the body 10, the cooking chamber 17 includes two opposing sidewalls. One of the sidewalls is adjacent to the first chamber 15, and the other sidewall is adjacent to the second chamber 16. The air inlet 1333 is opened on the sidewall adjacent to the first chamber 15, and the exhaust port 1334 is opened on the sidewall adjacent to the second chamber 16. This arrangement increases the airflow path in the cooking chamber 17 and increases the contact area with the steam in the cooking chamber 17, thereby improving the steam discharge effect in the cooking chamber 17.

[0088] In some embodiments of this utility model, such as Figure 3 As shown, along the length X of the body 10, the cooking chamber 17 includes two opposing sidewalls. One of the sidewalls is adjacent to the first chamber 15, and the other sidewall is adjacent to the second chamber 16. An air inlet 1333 is opened on the sidewall adjacent to the first chamber 15, so that the cooking chamber 17 communicates with the first chamber 15 through the air inlet 1333. An exhaust port 1334 is opened on the sidewall adjacent to the second chamber 16, so that the cooking chamber 17 communicates with the second chamber 16 through the air inlet 1333.

[0089] Specifically, the front end face of the body 10 is provided with a loading / unloading port, through which the cooking cavity 17 is connected to the outside. In the width direction Y of the body 10, there is a first distance between the loading / unloading port and the air inlet 1333, which is the minimum distance between them. In the width direction Y of the body 10, there is a second distance between the loading / unloading port and the exhaust port 1334, which is the minimum distance between them. Setting the first distance to be less than the second distance allows the air inlet 1333 to be positioned further away from the loading / unloading port than the air inlet 1333.

[0090] During the cooking process, the cooking cavity 17 of the cooking appliance 100 is at a high temperature (higher than the ambient temperature and reaching the temperature required for cooking). The airflow flowing into the cooking cavity 17 from the first chamber 15 through the air inlet 1333 mixes with the high-temperature steam inside the cooking cavity 17. The mixed airflow is then discharged through the exhaust port 1334 to the second chamber 16 and exited through the second chamber 16. The mixed airflow in the cooking cavity 17 contains high-temperature steam, resulting in a higher temperature at the location of the exhaust port 1334. By setting the first distance to be less than the second distance, the air inlet 1333 is positioned further away from the outlet, thereby reducing the temperature rise at the outlet and thus reducing the adverse effects of high temperature on the user (such as burns).

[0091] In addition, such as Figure 5 As shown, in the width direction Y of the body 10, there is a first distance between the take-up and put-out port and the air inlet 1333, and a second distance between the take-up and put-out port and the exhaust port 1334. The first distance is set to be less than the second distance, so that the air inlet 1333 is set further away from the take-up and put-out port than the air inlet 1334. This setting can increase the distance between the air inlet 1333 and the exhaust port 1334, which further increases the flow path of airflow in the cooking cavity 17, and also further increases the contact area with the steam in the cooking cavity 17, thereby further improving the exhaust effect of the steam in the cooking cavity 17.

[0092] It should be noted that the exhaust port 1334 has a projection on the side wall where the air inlet port 1333 is located. Along the width direction Y of the body 10, the projection is positioned between and at intervals with the air inlet port 1333, or it can partially overlap with it. For example, the projection is positioned between and at intervals with the air inlet port 1333. This arrangement can further increase the distance between the air inlet port 1333 and the exhaust port 1334, thereby further increasing the flow path of airflow in the cooking cavity 17 and further increasing the contact area with the steam in the cooking cavity 17, thus further improving the steam discharge effect in the cooking cavity 17.

[0093] In some embodiments of this utility model, along the length X of the body 10, the cooking cavity 17 includes two opposing sidewalls. One of the sidewalls is adjacent to the first chamber 15, and the other sidewall is adjacent to the second chamber 16. An air inlet 1333 is opened on the sidewall adjacent to the first chamber 15, so that the cooking cavity 17 communicates with the first chamber 15 through the air inlet 1333. An exhaust port 1334 is opened on the sidewall adjacent to the second chamber 16, so that the cooking cavity 17 communicates with the second chamber 16 through the air inlet 1333.

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

[0095] During cooking, the steam generated tends to float in the upper space of the cooking chamber 17. By setting the distance between the top wall and the air inlet 1333 to be smaller than the distance between the bottom wall and the air inlet 1333, the air inlet 1333 is positioned closer to the top wall of the cooking chamber 17. This allows the airflow to quickly mix with the steam after flowing into the cooking chamber 17 through the air inlet 1333, thereby increasing the contact opportunity with the steam and improving the steam discharge effect.

[0096] In some embodiments of this utility model, such as Figure 3 As shown, along the length X of the body 10, the cooking chamber 17 includes two opposing sidewalls. One of the sidewalls is adjacent to the first chamber 15, and the other sidewall is adjacent to the second chamber 16. An air inlet 1333 is opened on the sidewall adjacent to the first chamber 15, so that the cooking chamber 17 communicates with the first chamber 15 through the air inlet 1333. An exhaust port 1334 is opened on the sidewall adjacent to the second chamber 16, so that the cooking chamber 17 communicates with the second chamber 16 through the air inlet 1333.

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

[0098] During cooking, the steam generated tends to float in the upper space of the cooking chamber 17. By setting the distance between the top wall and the exhaust port 1334 to be smaller than the distance between the bottom wall and the exhaust port 1334, the exhaust port 1334 is positioned closer to the top wall of the cooking chamber 17. This allows the steam-mixed airflow in the cooking chamber 17 to be quickly discharged to the second chamber 16 through the exhaust port 1334 and then discharged to the outside of the body 10 through the air outlet 191. This further increases the contact opportunity with the steam, thereby improving the steam discharge effect.

[0099] It should be noted that along the height direction Z of the body 10, the height of the air inlet 1333 (the minimum distance between the air inlet 1333 and the bottom wall) and the height of the exhaust outlet 1334 (the minimum distance between the exhaust outlet 1334 and the bottom wall) may be the same or different. For example, the height of the air inlet 1333 may be less than the height of the exhaust outlet 1334. This arrangement allows for a further increase in the distance between the air inlet 1333 and the exhaust outlet 1334, thereby further increasing the airflow path within the cooking cavity 17 and the contact area with the steam within the cooking cavity 17, thus further improving the steam removal effect within the cooking cavity 17.

[0100] In some embodiments of this utility model, such as Figure 3 As shown, along the length X of the body 10, the cooking chamber 17 includes two opposing sidewalls. One of the sidewalls is adjacent to the first chamber 15, and the other sidewall is adjacent to the second chamber 16. An air inlet 1333 is opened on the sidewall adjacent to the first chamber 15, so that the cooking chamber 17 communicates with the first chamber 15 through the air inlet 1333. An exhaust port 1334 is opened on the sidewall adjacent to the second chamber 16, so that the cooking chamber 17 communicates with the second chamber 16 through the air inlet 1333.

[0101] Specifically, the body 10 includes a heating component. When the heating component is in operation, it can provide heat to 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] 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 intake 1333 can be an open structure (i.e., there is no obstruction at the opening position), a mesh structure (i.e., multiple small holes are opened in a certain area), or a louver structure (multiple guide plates are set at the opening position to form a louver structure).

[0104] In this application, such as Figure 5 As shown, the air inlet 1333 is configured as a first mesh, which can reduce the amount of foreign objects entering the cooking cavity 17 through the first chamber 15 while ensuring that the first chamber 15 is connected to the cooking cavity 17, thereby improving the hygiene level of the cooking cavity 17.

[0105] In addition, the aperture of the first mesh is less than a quarter wavelength of microwaves. This design allows the first mesh to shield microwaves when the heating component includes a microwave generating component, reducing microwave leakage at the air inlet 1333 and improving the safety performance of the body 10.

[0106] In some embodiments of this utility model, as shown in 3, the cooking cavity 17 includes two opposing sidewalls along the length X of the body 10. One of the sidewalls is adjacent to the first chamber 15, and the other sidewall is adjacent to the second chamber 16. An air inlet 1333 is opened on the sidewall adjacent to the first chamber 15, so that the cooking cavity 17 communicates with the first chamber 15 through the air inlet 1333. An exhaust port 1334 is opened on the sidewall adjacent to the second chamber 16, so that the cooking cavity 17 communicates with the second chamber 16 through the air inlet 1333.

[0107] Specifically, the body 10 includes a heating component. When the heating component is in operation, it can provide heat to 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] 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.

[0109] It should be noted that the exhaust vent 1334 can be an open structure (i.e., there is no obstruction at the opening), a mesh structure (i.e., multiple small-diameter holes are opened in a certain area), or a louver structure (multiple guide plates are set at the opening to form a louver structure).

[0110] In this application, such as Figure 5 As shown, the vent 1334 is configured as a second mesh, which can reduce the amount of foreign objects entering the cooking cavity 17 through the second chamber 16 while ensuring that the second chamber 16 is connected to the cooking cavity 17, thereby improving the hygiene level of the cooking cavity 17.

[0111] In addition, the aperture of the second mesh is smaller than a quarter wavelength of microwaves. This design allows the second mesh to shield microwaves when the heating component includes a microwave generating component, reducing microwave leakage at the exhaust port 1334 and improving the safety performance of the body 10.

[0112] In some embodiments of this utility model, a third chamber 19 is formed by the outer surface of the outer cover 11 and the cavity assembly 13. The third chamber 19 is located above the cooking cavity 17 along the height direction Z of the body 10. The air outlet 191 is located above the cooking cavity 17 and is connected to the third chamber 19. The second chamber 16 is connected to the third chamber 19.

[0113] By placing both the third chamber 19 and the air outlet 191 above the cooking chamber 17, top exhaust of the cooking appliance 100 is achieved. The top exhaust of the cooking appliance 100 (the exhaust air is hot air, which has a certain lift force; by placing the air outlet 191 and the third chamber 19 above the cooking chamber 17, the exhaust air will not make secondary contact with the cooking appliance 100 when it rises) reduces the impact of the exhaust air on other parts of the cooking appliance 100 (for example, the temperature of the cooking appliance 100 rises when the exhaust air blows onto it).

[0114] Furthermore, along the length of the body 10, the first chamber 15 and the second chamber 16 are located on opposite sides of the cooking cavity 17, and along the height Z of the body 10, the third chamber 19 is located above the cooking cavity 17. The first chamber 15, the cooking cavity 17, the second chamber 16, and the third chamber 19 are sequentially connected to form a heat dissipation duct. This duct covers the circumferential area of ​​the outer side of the cooking cavity 17, thereby reducing the transfer of heat from the cooking cavity 17 to the outside, thus reducing the temperature rise of the outer cover 11 and minimizing the possibility of burns to the cabinet or users due to the temperature rise of the outer cover 11.

[0115] In some embodiments of this utility model, such as Figure 2 or Figure 4 As shown, the cavity assembly 13 includes a first plate 131, a second plate 132, and a side panel 133. Along the width direction Y of the body 10, the first plate 131 and the second plate 132 are spaced apart and are parallel to each other. The first plate 131 is located in front of the second plate 132 (i.e., in front of the body 10). An air outlet 191 and a pick-up / placement port are respectively opened on the first plate 131. Along the height direction Z of the body 10, the air outlet 191 is located above the pick-up / placement port.

[0116] The side panel 133 is disposed between the first plate 131 and the second plate 132. The side panel 133 is a cylindrical structure with openings at both ends (both ends along the length direction X of the body 10). The end of the cylindrical structure facing the second plate 132 is connected to the second plate 132 (the connection method includes, but is not limited to, snap-fit, welding, or connection via connectors), and the opening on this side is closed by the second plate 132. The end of the cylindrical structure facing the first plate 131 is connected to the first plate 131 (the connection method includes, but is not limited to, snap-fit, welding, or connection via connectors), and the opening on this side is connected to the pick-up and put-out port. The opening of the cylindrical structure has the same shape and size as the pick-up and put-out port.

[0117] The cylindrical structure, the first plate 131 and the second plate 132 enclose the cooking cavity 17. On the outside of the cooking cavity 17, the first plate 131 and the second plate 132 protrude from the side panel 133 respectively. The protruding parts of the first plate 131 and the second plate 132 relative to the side panel are connected to the outer cover 11 respectively (the connection method includes but is not limited to snap-fit, welding or connection via connectors, etc.). The space enclosed by the outer cover 11, the first plate 131, the second plate 132 and the side panel 133 constitutes the structure of the first chamber 15 and the second chamber 16.

[0118] The cooking cavity 17 is enclosed by the cavity assembly 13, and the first chamber 15 and the second chamber 16 are enclosed by the cavity assembly 13 and the outer cover 11. The overall structure is simple and can effectively reduce the number of parts of the body 10, thereby facilitating assembly during the production process, effectively improving assembly efficiency, and thus reducing manufacturing costs.

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

[0120] It should be noted that the longitudinal section (the surface parallel to the first plate 131) of the cylindrical side panel 133 is quadrilateral. The side panel 133 can be a one-piece structure or a split structure.

[0121] For example, such as Figure 2 and Figure 5 As shown, the side panel 133 is a split structure, including a U-shaped panel 1331 and a top panel 1332. The top panel 1332 is connected to the U-shaped panel 1331 (the connection method includes, but is not limited to, snap-fit, welding, or connection via connectors), and closes the top opening of the U-shaped panel 1331, thereby forming a cylindrical structure. Setting the side panel 133 as a split structure improves the ease of processing.

[0122] In some embodiments of this utility model, such as Figure 3As shown, the cavity assembly 13 includes a first plate 131, a second plate 132, and a side panel 133. Along the width direction Y of the body 10, the first plate 131 and the second plate 132 are spaced apart and are parallel to each other. The first plate 131 is located in front of the second plate 132 (i.e., in front of the body 10). An air outlet 191 and a pick-up / placement port are respectively opened on the first plate 131. Along the length direction X of the body 10, the air outlet 191 is located on one side of the pick-up / placement port. The side panel 133 is disposed between the first plate 131 and the second plate 132. The side panel 133 is a cylindrical structure. Both ends of the cylindrical structure (both ends along the length direction X of the machine body 10) are respectively provided with openings. The end of the cylindrical structure facing the second plate 132 is connected to the second plate 132, and the opening on this side is closed by the second plate 132. The end of the cylindrical structure facing the first plate 131 is connected to the first plate 131, and the opening on this side is connected to the pick-up and put-out port. The opening of the cylindrical structure and the pick-up and put-out port have the same shape and size.

[0123] Specifically, on the outside of the cylindrical side panel 133, the second plate 132 is located opposite the side panel 133 along the length direction X of the body 10. The portion of the second plate 132 located outside the side panel 133 includes a first part and a second part arranged in opposite directions. The first part encloses a portion of the first chamber 15, and the second part encloses a portion of the second chamber 16. An air inlet 1321 is provided on the first part.

[0124] The air inlet 1321 is set on the first part of the second plate 132, so that the body 10 can take in air from the rear side when it is running. The air outlet 191 is located on the front side of the body 10 and exits air towards the front of the body 10. This arrangement enables the heat dissipation air duct to take in air from the rear side and exit air from the front side when dissipating heat, thereby reducing the interference between the air intake and air exhaust, and thus improving the heat exchange effect of the body 10.

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

[0126] It should be understood that, on the outside of the cylindrical side panel 133, the second plate 132 is configured to protrude from the side panel 133. The protruding part of the second plate 132 from the side panel 133 can be connected to the outer cover 11, and together with the outer cover 11, they enclose the structure of the first chamber 15 and the second chamber 16. This simplifies the structure of the cavity assembly 13 of the body 10, effectively reducing the manufacturing cost of the cavity assembly 13. In addition, the structure of the cavity assembly 13 is easy to assemble, which can improve the assembly efficiency and further reduce the manufacturing cost.

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

[0128] In some embodiments of this utility model, such as Figure 3 As shown, the body 10 has a first chamber 15 and a second chamber 16 respectively in its length direction X, and the first chamber 15 and the second chamber 16 are located on opposite sides of the cooking cavity 17. The air inlet 1321 is connected to the first chamber 15, and the air outlet 191 is connected to the second chamber 16.

[0129] Specifically, the fan assembly 18 is disposed within the first chamber 15, and the fan assembly 18 is positioned opposite the air inlet 1321. The fan assembly 18 and the air inlet 1321 can be spaced apart or not spaced apart. For example, the fan assembly 18 and the air inlet 1321 are not spaced apart, that is, the fan assembly 18 rests against the portion of the second plate 132 that protrudes from the side panel 133, and the inlet of the fan assembly 18 abuts against the air inlet 1321. When the fan assembly 18 is running, the external airflow directly enters the fan assembly 18 through the air inlet 1321 and then enters the first chamber 15 through the fan assembly 18. This arrangement can increase the rate at which the airflow enters the first chamber 15.

[0130] like Figure 2 As shown, a power device group 14 (such as a frequency converter, magnetron, etc.) of the organism 10 is also installed in the first chamber 15. The power device group 14 is positioned between the fan assembly 18 and the air inlet 1333 of the cooking chamber 17. This arrangement ensures that when the fan is running, the airflow enters the first chamber 15 through the air inlet 1321 and first passes through the power device group 14. The airflow then exchanges heat with the power device group 14, reducing its temperature rise and thus lowering its failure rate.

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

[0132] In some embodiments of this utility model, such as Figure 3 As shown, the body 10 includes an outer cover 11 and a cavity assembly 13. The outer cover 11 covers the outside of the cavity assembly 13 and is connected to the cavity assembly 13. A portion of the outer cover 11 is spaced apart from a portion of the outer surface of the cavity assembly 13. The cooking cavity 17 is formed by the cavity assembly 13. The first chamber 15 and the second chamber 16 are formed by the outer cover 11 and a portion of the outer surface of the cavity assembly 13. The cavity assembly 13 includes a first plate 131, a second plate 132, and a side panel 133. Along the width direction Y of the body 10, the first plate 131 and the second plate 132 are spaced apart and parallel to each other. The first plate 131 is located in front of the second plate 132 (i.e., in front of the body 10). An air outlet 191 and a loading / unloading port are respectively opened on the first plate 131. Along the length direction X of the body 10, the air outlet 191 is located on one side of the loading / unloading port.

[0133] A side panel 133 is disposed between the first plate 131 and the second plate 132. The side panel 133 is a cylindrical structure with openings at both ends (both ends along the length X of the machine body 10). The end of the cylindrical structure facing the second plate 132 is connected to the second plate 132, and the opening on this side is closed by the second plate 132. The end of the cylindrical structure facing the first plate 131 is connected to the first plate 131, and the opening on this side is connected to the loading / unloading port. The cylindrical structure, the first plate 131, and the second plate 132 enclose the cooking cavity 17.

[0134] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the body 10 also includes a door 12, which is connected to the first plate 131. The door 12 can open and close relative to the first plate 131. The opening and closing of the door 12 is used to open or close the loading and unloading port on the first plate 131, thereby realizing the opening or closing operation of the cooking cavity 17.

[0135] Among them, such as Figure 6As shown, the air guide structure 111 is a protruding structure formed by the outer cover 11 in the direction away from the cavity assembly 13, and the protruding structure and the cavity assembly 13 surround the air outlet 191. By setting the position of the air outlet 191, there is no need to set up a separate air guide cover or other structures for the airflow, which reduces the number of parts, simplifies the assembly process, improves the assembly efficiency, and reduces the manufacturing cost.

[0136] In some embodiments of this application, the air guide structure 11, which is a raised structure, is a press-formed structure formed on the outer cover 11.

[0137] Specifically, the air guide structure 111 is recessed on the side away from the cavity assembly 13 to form a compression shape, and the air guide structure 111 is connected to part of the edge of the outer cover 11, so that the air guide structure 111 forms a gathering structure on the outer cover 11. After the airflow in the heat dissipation duct flows into the position of the air guide structure 111, the air guide structure 111 gathers the airflow and discharges it uniformly, thereby increasing the airflow rate and improving the airflow discharge efficiency.

[0138] In addition, the air guide structure 111 is formed by stamping, and the shape of the cross section (the surface perpendicular to the height direction of the body) of the air guide structure can be semi-circular or polygonal (e.g., triangle, quadrilateral or trapezoid). For example, the air guide structure 111 is a rectangular structure (with a quadrilateral cross-section). The length (dimension along the length direction of the body 10) of the rectangular structure is in the range of 100 to 440 mm (e.g., 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 (dimension along the width direction of the body 10) is in the range of 20 to 280 mm (e.g., 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 (dimension along the height direction of the body 10) is in the range of 2 to 10 mm (e.g., 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 this application, the protruding structure protrudes from the door body 12, and the airflow discharged from the air outlet 191 is discharged from the top of the door body 12.

[0140] By placing both the third chamber 19 and the air outlet 191 above the cooking chamber 17, top exhaust of the cooking appliance 100 is achieved. The top exhaust of the cooking appliance 100 (the exhaust air is hot air, which has a certain lift force; by placing the air outlet 191 and the third chamber 19 above the cooking chamber 17, the exhaust air will not make secondary contact with the cooking appliance 100 when it rises) reduces the impact of the exhaust air on other parts of the cooking appliance 100 (for example, the temperature of the cooking appliance 100 rises when the exhaust air blows onto it).

[0141] It should be noted that the connection between the door 12 and the first plate 131 can be achieved through a hinge or a sliding track. For example, the door 12 and the first plate 131 can be connected by a hinge, and the opening or closing of the loading and unloading port of the cooking cavity 17 can be achieved by pivoting the door 12 relative to the first plate 131. Setting the door 12 and the first plate 131 to be pivotally connected facilitates the user's operation of the door 12 during use and improves the convenience of the user.

[0142] In addition, the door 12 includes a door frame and a door glass. The door frame is connected to the first plate 131, and the door glass is embedded in the door frame. The door glass has a light-transmitting structure, allowing the user to observe the condition inside the cooking cavity 17 through the door glass. This enables the user to understand the cooking status of the food inside the cooking cavity 17 in a timely manner, improving the convenience of the user during use.

[0143] Furthermore, to reduce the temperature rise of the door body 12, a corresponding heat dissipation structure can be installed inside the door body 12. This structure reduces the temperature rise of the door body 12, minimizing the adverse effects on the user. For example, an air duct can be installed inside the door body 12, connected to the outside environment. A small fan or other airflow-driven component can be installed within the duct to circulate airflow between the duct and the outside environment, thereby reducing the temperature rise of the door body 12 and minimizing the risk of burns to the user. Alternatively, a cavity can be installed inside the door body 12, containing a phase change material (such as paraffin wax). This material absorbs the heat transferred to the door body 12, further reducing the temperature rise and minimizing the risk of burns to the user.

[0144] In some embodiments of this utility model, 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. The existence of the gap affects the harmony of the cabinet's appearance.

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

[0146] It should be noted that the outer frame 20 can be a metal frame or a non-metal frame. For example, the outer frame 20 can be a plastic frame. Plastic frames are low in manufacturing cost and lightweight, which can reduce the weight of the cabinet. At the same time, the color of the outer frame 20 can be set to match the cabinet, further improving the consistency of the overall appearance of the cabinet.

[0147] In addition, the connection methods between the outer frame 20 and the body 10 include, but are not limited to, snap-fitting, adhesive bonding, or connection through connectors.

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

[0149] By setting the air vent 191 opposite to the space 30, the air vent 191 is concealed, thereby improving the appearance harmony of the cooking appliance 100.

[0150] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
