Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to a cooking appliance. Background Technology

[0002] Cooking utensils are used to cook food, but the cooking space created within them is usually fixed, meaning the cooking space cannot be matched to the size of the food. When a cooking utensil has a large cooking space, if smaller food items need to be cooked, they still need to be placed within that larger space, thus affecting the cooking efficiency. Conversely, when a cooking utensil has a small cooking space, it cannot accommodate larger food items.

[0003] In related technologies, the cooking space is divided by arranging partitions in the cooking cavity to form a cooking space that matches the volume of the ingredients. However, when cooking smaller ingredients, there are still problems of wasted space and reduced cooking efficiency. Summary of the Invention

[0033] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0034] The following is for reference. Figures 1-3 The cooking appliance 100 according to the embodiments of this application is described. The cooking appliance 100 can be used to cook food ingredients, such as steaming, baking and other cooking operations.

[0035] According to an embodiment of this application, a cooking appliance 100 includes a shell assembly 1 and a door assembly 2.

[0036] Combination Figure 1 and Figure 2 As shown, the shell assembly 1 includes a first shell 11 and a second shell 12 arranged vertically.

[0037] The first housing 11 has a first cavity, and the second housing 12 has a second cavity. The first cavity and the second cavity are vertically connected and together form a cooking cavity (not shown) that opens to one side. The position of the first housing 11 relative to the second housing 12 in the vertical direction is adjustable so that the volume of the cooking cavity can be adjusted by adjusting the vertical overlap size of the first cavity and the second cavity. Thus, the overlap space of the first cavity and the second cavity can be adjusted by adjusting the relative position of the first housing 11 and the second housing 12 in the vertical direction, thereby adjusting the cooking space size of the cooking cavity formed by the first cavity and the second cavity.

[0038] Reference Figure 1 and Figure 2 As shown, the adjustment range of the first housing 11 relative to the second housing 12 includes a first position and a second position. That is, the first housing 11 can be held at either the first or the second position relative to the second housing 12. Simultaneously, the first housing 11 can also be held at a position between the first and second positions relative to the second housing 12, so as to adjust the overlapping area of ​​the first and second cavities according to the cooking space size requirements of the cooking cavity.

[0039] Specifically, a first housing 11 covers a second housing 12, and the first housing 11 has a downwardly opening first cavity. The second housing 12 is disposed below the first housing 11 and has an upwardly opening second cavity. The first cavity and the second cavity communicate with each other and together form a cooking cavity. (Refer to...) Figure 1 When the first housing 11 is in the first position relative to the second housing 12, the vertical overlap area between the first cavity and the second cavity is minimized, and the cooking space size of the cooking cavity jointly formed by the first cavity and the second cavity is maximized, thus meeting the cooking needs of larger ingredients; refer to Figure 2 When the first housing 11 is in the second position relative to the second housing 12, the overlap area between the first cavity and the second cavity in the vertical direction is the largest, and the cooking space size of the cooking cavity jointly formed by the first cavity and the second cavity is the smallest.

[0040] It should be noted that this application adjusts the size of the overlapping area of ​​the first cavity and the second cavity by adjusting the relative position of the first shell 11 and the second shell 12 in the vertical direction, thereby realizing the adjustment of the cooking space size of the cooking cavity, which can meet the cooking needs of ingredients of different sizes.

[0041] Furthermore, the door assembly 2 is mounted on the housing assembly 1, and the door assembly 2 is located on the open side of the cooking cavity to close the cooking cavity, thereby preventing heat from the cooking cavity from escaping from the open side of the cooking cavity and ensuring the cooking effect on the food.

[0042] Combination Figure 1 and Figure 2 As shown, the door assembly 2 has multiple door bodies 21, and the multiple door bodies 21 can be arranged coplanarly. Moreover, at least two door bodies 21 can be overlapped, so that different door structures with different shielding areas can be formed by adjusting the arrangement of the multiple door bodies, so as to match the door structure with the shell assembly.

[0043] Combined photos Figure 1 and Figure 2 Taking door assembly 2, which includes two door bodies 21 (including a first door body 211 and a second door body 212), as an example. (Refer to...) Figure 1 When the cooking space of the cooking cavity defined by the first housing 11 and the second housing 12 is large, the two doors 21 can be arranged coplanarly so that the open side of the cooking cavity can be blocked by the two doors 21 together; see reference Figure 2 When the cooking space size of the cooking cavity defined by the first shell and the second shell is small, the two doors 21 can be stacked and arranged so that the open side of the cooking cavity can be blocked by one of the two doors 21 (such as the first door 211).

[0044] Therefore, the cooking appliance 100 of this application can adjust the overlapping area of ​​the first cavity and the second cavity by adjusting the relative position between the first shell 11 and the second shell 12 according to cooking needs, so as to adjust the cooking space size of the cooking cavity. Furthermore, the multiple door bodies 21 in the door assembly 2 can adjust the matching method according to the size of the cooking cavity formed by the shell assembly 1, such as: multiple door bodies 21 are arranged in a coplanar manner, or at least two of the multiple door bodies 21 are stacked, so as to match the door structure formed by the door assembly 2 with the shell assembly 1 and ensure the sealing effect of the cooking cavity.

[0045] Reference Figure 1 and Figure 2 As shown, the door assembly 2 includes two door bodies 21, and the two door bodies 21 have two ways of mating. (Refer to...) Figure 1 The two door bodies 21 are arranged vertically and coplanarly. At this point, the door structure formed by the door assembly 2 is large, allowing it to cover a larger area, thus enabling the door assembly 2 to match the larger cooking volume of the shell assembly 1; see reference. Figure 2 The two door bodies 21 are stacked (i.e., opposite and close together) in the open direction of the cooking cavity. At this time, the door structure formed by the door assembly 2 has a small size, which can cover a small area, so that the door assembly 2 can match the shell assembly 1 with a small cooking volume. It should be noted that the above description of the door structure size as "large" and "small" refers to the size of the door assembly 2 in two usage states.

[0046] In the cooking appliance 100, cooking cavities of various volumes can be formed by adjusting the relative positions of the first housing 11 and the second housing 12. The open size of the cooking cavity is defined by the first housing 11 and the second housing 12. The open size of the cooking cavity is smaller for the smaller volume cooking cavity and larger for the larger volume cooking cavity.

[0047] Reference Figure 1 When the cooking cavity formed by the first housing 11 and the second housing 12 has the largest volume, the multiple door bodies 21 in the door assembly 2 are coplanarly arranged and correspondingly form a door structure with the largest shielding range; refer to Figure 2 When the volume of the cooking cavity formed by the first housing 11 and the second housing 12 is at its minimum, the door bodies 21 in the door assembly 2 can be stacked and arranged to block the open opening size of the cooking cavity. Specifically, by adjusting the arrangement of the multiple door bodies 21 (e.g., coplanar arrangement, stacked arrangement), the multiple door bodies 21 can be constructed into a door structure that matches the open opening size of the cooking cavity formed by the housing assembly 1. In other words, the arrangement of the multiple door bodies 21 in the door assembly 2 can be adjusted according to the size of the cooking cavity formed by the housing assembly 1 to ensure the sealing effect of the door assembly 2 on the open opening of the cooking cavity.

[0048] It should be noted that the cooking appliance 100 is used to cook food, and the cooking space formed within the cooking appliance 100 is usually fixed, resulting in the cooking space not being able to match the volume of the food. When the cooking appliance 100 has a large cooking space, if smaller food needs to be cooked, the food still needs to be placed in a larger cooking space, thus affecting the cooking efficiency of the cooking appliance 100. When the cooking appliance 100 has a small cooking space, the cooking space cannot meet the placement requirements of larger food. In related technologies, the cooking space is divided by arranging partitions in the cooking cavity to form a cooking space that matches the volume of the food, but this still results in wasted space and reduced cooking efficiency when cooking smaller food.

[0049] In this application, the relative positions of the first housing 11 and the second housing 12 are adjustable, thereby allowing the cooking cavities of various volumes to be defined by adjusting the vertical overlap area of ​​the first and second cavities. Furthermore, the door assembly 2 can be configured to form a door structure matching the volume of the cooking cavities by changing the fit between multiple door bodies 21, ensuring the door assembly 2 provides effective shielding and sealing of the cooking cavities at their open openings. Therefore, the cooker can be adjusted according to the cooking requirements of the ingredients, enabling the cooker 100 to form a cooking cavity that matches the volume of the ingredients, improving the versatility of the cooker 100 and meeting the cooking needs of various ingredients.

[0050] It is understood that, according to the embodiments of this application, the cooking appliance 100 can adjust the size of the cooking cavity formed by the shell assembly 1 by adjusting the relative position of the first shell 11 and the second shell 12 in the vertical direction, so that the cooking appliance 100 can form a cooking space that matches the volume of the food, which helps to improve the cooking efficiency and cooking effect of the cooking appliance 100 on the food.

[0051] Combination Figure 1 and Figure 2 As shown, in some embodiments of this application, the plurality of doors 21 include a first door 211 and a second door 212. The first door 211 is connected to the second housing 12 to realize the connection and cooperation between the door assembly 2 and the housing assembly 1. The second door is connected to the first door, and the second door 212 can be located on the side of the first door 211 away from the cooking cavity when it is arranged overlapping with the first door 211, and the open side of the cooking cavity is closed only by the first door 211.

[0052] The connection and cooperation method between the second door 212 and the first door 211 can include, but is not limited to, hinge connection, detachable connection, etc., as long as it can meet the position change of the first door 211 and the second door 212.

[0053] Combination Figure 1 and Figure 2 As shown in a further embodiment of this application, the door 21 includes a first door 211 and a second door 212. The first door 211 is rotatably mounted on the second housing 12 about a first axis, and the second door 212 is rotatably connected to the first door 211 about a second axis. The second door 212 can switch between a coplanar mating position and a stacked mating position relative to the first door 211.

[0054] Reference Figure 1 When the cooking cavity is at its maximum volume, the second door 212 is in a coplanar mating position relative to the first door 211. The second door 212 and the first door 211 are coplanarly arranged so that the first door 211 and the second door 212 together shield the open side of the cooking cavity; refer to... Figure 2 When the volume of the cooking cavity is at its minimum, the second door 212 is in a stacked position relative to the first door 211. The second door 212 and the first door 211 are arranged opposite to and close to each other, and the second door 212 is located on the side surface of the first door 211 away from the shell assembly 1, so that the open side of the cooking cavity is only blocked by the first door 211.

[0055] Combination Figure 1 and Figure 2As shown, a first housing 11 covers a second housing 12, with the second housing 12 positioned below the first housing 11. The vertical position of the first housing 11 relative to the second housing 12 is adjustable. When the first housing 11 is moved downward relative to the second housing 12, the size of the cooking space defined between the first housing 11 and the second housing 12 decreases; when the first housing 11 is moved upward relative to the second housing 12, the size of the cooking space defined between the first housing 11 and the second housing 12 increases.

[0056] The first door 211 and the second door 212 are rotatably connected, and the second door 212 can be mounted on the second housing 12 through the first door 211. That is, the second door 212 and the housing assembly 1 are indirectly connected and fitted. When it is necessary to cover the open opening of the cooking cavity with the first door 211 and the second door 212, the first door 211 and the second door 212 are arranged on the same plane. When it is only necessary to cover the open opening of the cooking cavity with the first door 211, the second door 212 is flipped to the side of the first door 211 that is away from the cooking cavity, and the second door 212 is opposite to and fitted to the first door 211, so that the first door 211 and the second door 212 are stacked and arranged so that the first door 211 and the second door 212 fit together tightly, and the second door 212 is arranged in a position suitable for avoiding the housing assembly 1.

[0057] In this application, the position of the second door 212 relative to the first door 211 is adjusted by flipping the second door 212, thereby forming door structures of various sizes, and then matching the size of the door structure with the size of the shell assembly 1. The adjustment method of the door assembly 2 is simple, and there is no need to disassemble the door 21, which can reduce the operational difficulty of the adjustment process of the cooking appliance 100.

[0058] It should be noted that after the positions of the first door body 211 and the second door body 212 are adjusted, the relative positions between the first door body 211 and the second door body 212 are fixed to improve the reliability of the door structure formed by the first door body 211 and the second door body 212 in use and to ensure the strength of the door structure when it is opened or closed.

[0059] In some embodiments, a connecting structure is provided between the first door body 211 and the second door body 212 so that the first door body 211 and the second door body 212 are positioned by the connecting structure, such as: the first door body 211 and the second door body 212 are kept in a coplanar arrangement by the connecting structure, or the first door body 211 and the second door body 212 are kept in a relative and close arrangement by the connecting structure.

[0060] In some specific embodiments, the connection structure may include a positioning pin, which is adapted to position and engage the first door body 211 and the second door body 212 after the positions of the first door body 211 and the second door body 212 have been adjusted. For example, pin holes are respectively provided on the first door body 211 and the second door body 212, so that after the positions of the first door body 211 and the second door body 212 are adjusted, the positioning pin engages with the pin hole to fix the first door body 211 and the second door body 212. It can be understood that the first door body 211 and the second door body 212 may have two sets of corresponding pin holes, so that the first door body 211 and the second door body 212 have a set of corresponding pin holes when they are in two different engagement positions, and the positioning pin engages with the set of pin holes to fix the first door body 211 and the second door body 212.

[0061] It should be noted that the positioning form between the first door body 211 and the second door body 212 is not limited to this. The connection structure may also include a magnetic structure, a snap-fit ​​structure, etc., as long as it can position the first door body 211 and the second door body 212 in two mating positions.

[0062] In some embodiments of this application, there are multiple second doors 212, one of which is connected to the first door 211. The multiple second doors 212 can be arranged coplanarly and sequentially along the vertical direction. Any two adjacent second doors 212 can be connected in a flipped manner to selectively arrange two adjacent second doors 212 opposite to each other and fit together.

[0063] This allows the door assembly 2 to have multiple matching methods, forming door structures of various sizes through a first door body 211 and multiple second door bodies 212, thereby matching the door assembly 2 with cooking cavities of various sizes, enabling the cooking appliance 100 to cook food with cooking cavities of various sizes.

[0064] It is understandable that when the door assembly 2 is composed of a first door body 211 and two second door bodies 212, the first door body 211 and the two second door bodies 212 can be arranged coplanarly to form a door structure, at which time the door structure size is the largest; the first door body 211 and the second door body 212 arranged adjacent to it can also be arranged coplanarly, and the two second door bodies 212 can be arranged opposite each other and attached to form a door structure, at which time the door structure size is reduced by the covering area of ​​one second door body 212 compared to the largest door structure size; the first door body 211 and the two second door bodies 212 can also be stacked, at which time the door structure size is the smallest, and the open opening of the cooking cavity is covered only by the first door body 211. In other words, the more door bodies 21 there are in the door assembly 2, the more door structure sizes can be formed by the door assembly 2. When the door assembly 2 has two door bodies 21, the open opening of the cooking cavity can be blocked by two sizes of door structures; when the door assembly 2 has three door bodies 21, the open opening of the cooking cavity can be blocked by three sizes of door structures.

[0065] Combination Figure 1 and Figure 2 As shown, in some embodiments of this application, the first door body 211 is provided with a first mounting opening 2111 extending through the thickness direction, and a first viewing element 2112 is provided within the first mounting opening 2111. The second door body 212 is provided with a second mounting opening 2121 extending through the thickness direction, and a second viewing element 2122 is provided within the second mounting opening 2121. When the first door body 211 and the second door body 212 are arranged opposite to each other, the first viewing element 2112 and the second viewing element 2122 are arranged opposite to each other.

[0066] During the cooking process of the cooking appliance 100, the door assembly 2 covers the open opening of the cooking cavity, and the user can observe the food in the cooking cavity through the first transparent piece 2112 and the second transparent piece 2122 of the door assembly 2 so that the user can understand the current cooking status of the food in a timely manner.

[0067] Specifically, when the first door body 211 and the second door body 212 in the door assembly 2 are arranged coplanarly, the user can observe the food inside the cooking cavity through either the first viewing element 2112 or the second viewing element 2122. When the first door body 211 and the second door body 212 in the door assembly 2 are stacked, the first viewing element 2112 and the second viewing element 2122 are positioned opposite each other in the stacking direction of the first door body 211 and the second door body 2122, allowing the user to observe the food inside the cooking cavity through the first viewing element 2112 and the second viewing element 2122 in sequence. Thus, even if the arrangement of the door bodies 21 in the door assembly 2 changes, the user's need to observe the food inside the cooking cavity can still be met.

[0068] It is understood that in this application, each door body 21 (e.g., the first door body 211 and the second door body 212) is provided with an installation port (i.e., the first installation port 2111 and the second installation port 2121 mentioned above), and a viewing element (i.e., the first viewing element 2112 and the second viewing element 2122 mentioned above) is provided at the installation port, so that a viewing window can be formed on each door body 21, allowing the user to observe the food in the cooking cavity from the viewing window of the door body 21.

[0069] Reference Figure 1 When the door assembly 2 is in the unfolded state, the first door body 211 and the second door body 212 are arranged coplanarly, allowing the user to observe the interior of the cooking cavity through two viewing windows formed on the first door body 211 and the second door body 212, respectively; (Refer to...) Figure 2 When the door assembly 2 is in the folded state, the first door body 211 and the second door body 212 are positioned opposite each other, and the user can observe the inside of the cooking cavity through the two viewing windows formed on the second door body 212 and the first door body 211 in turn.

[0070] In some embodiments of this application, the first transparent element 2112 is constructed as a glass element, which has a good transparent effect and makes it easy for users to observe the inside of the cooking cavity.

[0071] In some embodiments of this application, the second transparent element 2122 is constructed as a glass element, which has a good transparent effect and makes it easy for users to observe the inside of the cooking cavity.

[0072] The first perspective element 2112 and the second perspective element 2122 can both be constructed as glass elements.

[0073] It should be noted that the glass components can be constructed as multi-layered glass. This multi-layered structure effectively disperses thermal stress, reducing the risk of glass shattering due to sudden temperature changes. Simultaneously, the multi-layered glass effectively blocks heat loss, improving the oven's insulation performance, reducing energy consumption, and maintaining temperature uniformity.

[0074] In some embodiments, an adhesive material may be sandwiched between the multiple layers of glass. Even if the glass shatters, the adhesive material can prevent the glass shards from flying and improve the safety of the door assembly 2. In some embodiments, the glass components are preferably heat-resistant glass (such as tempered glass). Heat-resistant glass has a small coefficient of expansion and can withstand high temperatures.

[0075] like Figure 1As shown, in some embodiments of this application, the first mounting port 2111 and the second mounting port 2121 have the same shape and size. Moreover, when the first door body 211 and the second door body 212 are arranged opposite each other, the first mounting port 2111 and the second mounting port 2121 coincide in the projection of the first door body 211 and the second door body 212 in the stacking direction. This allows the first mounting port 2111 and the second mounting port 2121 to correspond fully, so that the first transparent element 2112 and the second transparent element 2122 can be arranged accordingly, ensuring the user's observation effect on the food in the cooking cavity.

[0076] Reference Figure 1 As shown, in a specific embodiment of this application, a first mounting opening 2111 is formed in the central region of the first door body 211, and the first mounting opening 2111 is constructed as a rectangular opening, with a distance L1 between the upper edge of the rectangular opening and the top edge of the first door body 211; a second mounting opening 2121 is formed in the central region of the second door body 212, and the second mounting opening 2121 is constructed as a rectangular opening, with a distance L2 between the lower edge of the rectangular opening and the bottom edge of the first door body 211. Furthermore, the aspect ratio and dimensions of the rectangular opening formed by the first mounting opening 2111 are the same as those of the rectangular opening formed by the second mounting opening 2121.

[0077] Where L1 = L2, when the second door 212 flips downward relative to the first door 211, the upper edge of the second mounting port 2121 (i.e. the lower edge before flipping) can be aligned with the upper edge of the first mounting port 2111, so that the first mounting port 2111 and the second mounting port 2121 are fully corresponding.

[0078] like Figure 1 As shown, in some embodiments of this application, the first perspective element 2112 and the second perspective element 2122 have the same shape and size. Moreover, when the first door body 211 and the second door body 212 are arranged opposite each other, the projection of the first perspective element 2112 and the projection of the second perspective element 2122 coincide in the projection of the first door body 211 and the second door body 212 in the stacking direction. This makes the first perspective element 2112 and the second perspective element 2122 fully correspond, so that the visible area corresponding to the first perspective element 2112 and the second perspective element 2122 is large enough, increasing the user's observation range.

[0079] It is understandable that when the first mounting port 2111 and the second mounting port 2121 have the same shape and size, and the first transparent element 2112 and the second transparent element 2122 have the same shape and size, the first transparent element 2112 and the second transparent element 2122 in the folded first door body 211 and the second door body 212 can be fully aligned to ensure that the user can observe the inside of the cooking cavity through the first transparent element 2112 and the second transparent element 2122.

[0080] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the cooking appliance 100 also includes a control panel 3. The control panel 3 is disposed on the first door 211 and is located on the side of the first mounting opening 2111 away from the second door 212. When the second door 212 is disposed opposite to the first door 211, the control panel 3 and the second door 212 are offset in the vertical direction, so that the control panel 3 can be fully exposed, making it convenient for the user to operate the control panel 3 and providing convenience for the user to use the cooking appliance 100.

[0081] Reference Figure 1 As shown, the first door 211 serves as the mounting carrier for the control panel 3, thereby integrating the control panel 3 onto the first door 211. This helps improve the integration of the cooking appliance 100 and saves the space required for the control panel 3. Furthermore, when the first door 211 and the second door 212 are in the unfolded state, the control panel 3 can be fully exposed, facilitating user operation from the control panel 3.

[0082] Further integration Figure 2 As shown, the size of the first door body 211 is larger than the size of the second door body 212. When the first door body 211 and the second door body 212 are stacked, the control panel 3 is located in the area below the second door body 212, thus fully exposing the control panel 3. Therefore, even when the door assembly 2 is in the folded state, the user's need to operate the control panel 3 can still be met.

[0083] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the control panel 3 is embedded in the first door body 211, thereby saving the space occupied by the control panel 3 and improving the integration effect of the control panel 3 at the door assembly 2.

[0084] The first door body 211 has an outwardly open mounting groove. The control panel 3 can be embedded in the mounting groove and is engaged with the first door body 211 to fix the control panel 3 to the first door body 211. This makes the assembly of the control panel 3 and the first door body 211 highly reliable, simple to assemble, and easy to operate.

[0085] It should be noted that the "outer side" of the first door 211 refers to the side of the first door 211 that faces away from the cooking cavity when the shell assembly 1 is closed. Furthermore, the assembly method between the first door 211 and the control panel 3 may include, but is not limited to, screw connection.

[0086] like Figure 2 and Figure 3As shown, in some embodiments of this application, the cooking appliance 100 further includes a first hinge assembly 41, which is used to rotatably mount the first door 211 onto the second housing 12 about a first axis, thereby enabling the opening and closing adjustment of the cooking cavity on the open side through the rotatable engagement of the first door 211 and the second door 212. It is understood that the first hinge assembly has a first hinge axis, and the first axis is the central axis of the second hinge axis.

[0087] In some embodiments of this application, the first axis is set parallel to the horizontal direction, so that the first door 211 can be flipped up or down relative to the second housing 12 to realize the vertical opening and closing action of the door structure relative to the housing assembly 1.

[0088] When the second housing 12 is positioned below the first housing 11, the first hinge assembly 41 is located at the bottom of the second housing 12, allowing the first door 211 to flip downwards around the first axis, thus opening the door structure. It is understood that during the position adjustment of the first door 211 relative to the second housing 12, the first door 211 can drive the second door 212 to move synchronously relative to the housing assembly 1. Furthermore, the downward flipping opening method allows the door structure to be adjusted to a position that fully avoids the open opening of the cooking cavity, facilitating the user's loading and unloading of ingredients.

[0089] In some other embodiments of this application, the first axis is set perpendicular to the horizontal direction (i.e., the first axis extends vertically), so that the first door 211 can be flipped to the left or right relative to the second housing 12 to realize the lateral opening and closing action of the door structure relative to the housing assembly 1.

[0090] The second housing 12 has two sidewalls arranged opposite each other in the left-right direction. The first hinge assembly 41 is disposed on one of the two sidewalls and is located in the area corresponding to the first door 211 and the second housing 12. When the first hinge assembly is connected to the left sidewall of the second housing 12, the first door 211 can be opened from right to left relative to the second housing 12; when the first hinge assembly is connected to the right sidewall of the second housing 12, the first door 211 can be opened from left to right relative to the second door 212.

[0091] In this application, the first door body 211 in the door assembly 2 is rotatably connected to the second housing 12 through the first hinge assembly, and the second door body 212 and the first door body 211 can be arranged in an unfolded coplanar arrangement or a folded stacked arrangement, and the first door body 211 can drive the second door body 212 to move synchronously, so as to realize the opening or closing of the door structure.

[0092] like Figure 2As shown, in some embodiments of this application, the door assembly 2 includes a second hinge assembly 42 for rotatably mounting the second door body 212 to the first door body 211 about a second axis. The second axis is parallel to the horizontal direction. It is understood that the second hinge assembly has a second hinge axis, and the second axis is the central axis of the second hinge axis.

[0093] Combination Figure 1 and Figure 2 As shown, when the first axis is horizontally positioned, the second door body 212 can be flipped from top to bottom to switch the door assembly 2 from the unfolded state to the folded state, which is simple and convenient. Therefore, the second hinge assembly can be used to achieve vertical rotation between the second door body 212 and the first door body 211, allowing for vertical adjustment of the door structure formed at the door assembly 2.

[0094] In some embodiments of this application, the door 21 is provided with a magnetic attractor, which can be used to magnetically fix it to the shell assembly 1 (e.g., the first shell 11 and the second shell 12). The first shell 11 and the second shell 12 in the shell assembly 1 can be constructed as metal shells, and the magnetic attractor can be constructed as a magnet. The door 21 can be attracted and engaged with the shell assembly 1 through the magnet, thus achieving a fixed connection between the door 21 and the shell assembly 1. It should be noted that the fixing and engagement method between the shell assembly 1 and the door 21 is not limited to magnetic engagement.

[0095] In some embodiments of this application, the first housing 11 is sleeved on the second housing 12, and the housing assembly 1 is provided with a guide mechanism. The guide mechanism is connected to the first housing 11 and the second housing 12 respectively, and the guide mechanism is used to guide the vertical adjustment of the position of the first housing 11 relative to the second housing 12, so as to improve the stability of the position adjustment process of the first housing 11 relative to the second housing 12.

[0096] In a further embodiment of this application, the guiding mechanism includes a guiding part and a guiding mating part. The guiding part is disposed on one of the first housing 11 and the second housing 12, and the guiding mating part is disposed on the other of the first housing 11 and the second housing 12.

[0097] In some embodiments, the guide portion can be configured as a guide groove, and the guide mating portion can be configured as a guide block, which can guide and mate with the guide groove. The guide block can also slide with the guide groove, and a roller can be provided on the guide block to roll and engage with the groove wall, thereby reducing the adjustment resistance between the first housing 11 and the second housing 12.

[0098] In other embodiments, the guiding mechanism can be constructed as an X-shaped hinge, that is, the guiding mechanism has two guide rails and two guide arms. The two guide rails are respectively arranged on the first housing 11 and the second housing 12 and are parallel to each other. The middle parts of the two guide arms are pivotally connected and arranged in an X shape. Each guide arm has a guide block at each end that guides and cooperates with the two guide rails. The guide block can slide in the guide rail. By adjusting the angle between the two guide arms, the position of the two guide rails in the vertical direction can be adjusted, thereby adjusting the position of the first housing 11 and the second housing 12.

[0099] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the door body 21 is provided with a handle 213, and in the fastening direction between the door assembly 2 and the shell assembly 1, at least part of the projection of the handle 213 falls outside the projection of the shell assembly 1, thereby setting the handle 213 to protrude from the shell assembly 1 so that it can be held by the user, so that the user can drive the door assembly 2 to move by driving the handle 213.

[0100] It is understood that the door assembly 2 may include multiple door bodies 21 (e.g., first door body 211, second door body 212), and each door body 21 may be provided with a handle 213, so that the user can drive the door body 21 to move by driving the handle 213, thereby realizing the adjustment of the cooperation mode of multiple door bodies 21, the opening and closing adjustment of the door structure, etc.

[0101] like Figure 1 and Figure 2 As shown in a specific embodiment of this application, both the first door body 211 and the second door body 212 are provided with handles 213. When it is necessary to adjust the engagement of the first door body 211 and the second door body 212, the handles 213 on the second door body 212 can be driven to rotate the second door body 212 relative to the first door body 211, so that the second door body 212 can be adjusted to unfold or fold and stacked on the same plane as the first door body 211, which can reduce the difficulty for users to adjust the door assembly 2.

[0102] Furthermore, after the positions of the first door body 211 and the second door body 212 are adjusted, the door structure formed by the first door body 211 and the second door body 212 can be adjusted by driving the handle 213 of the first door body 211 relative to the shell assembly 1 to realize the opening and closing actions of the door structure.

[0103] Reference Figure 1 As shown, when the first door 211 and the second door 212 are in the unfolded state, the user can drive the first door 211 to move the second door 212 synchronously by holding the handle 213 on the first door 211, thereby realizing the opening or closing action of the door 21; see reference Figure 2As shown, when the first door 211 and the second door 212 are in the folded state, the first door 211 is located on the side of the second door 212 that is close to the cooking cavity. The user can open the door structure by pushing the handle 213 of the first door 211 outward, and close the door structure by pushing the handle 213 of the second door 212 inward.

[0104] In some embodiments of this application, the cooking appliance 100 includes a heating component (not shown in the figure), which is disposed on at least one of the first housing 11 and the second housing 12 to heat the food in the cooking cavity and realize the cooking function of the cooking appliance 100.

[0105] In a further embodiment of this application, the heating assembly may include a first heating element, which is mounted on the first housing 11. The first housing 11 mainly includes a back plate, left and right side plates, and a top plate. Since the first housing 11 is fitted onto the second housing 12, the first heating element is preferably located on the top plate, so that the food in the cooking cavity can be heated from top to bottom.

[0106] In some embodiments of this application, the heating assembly may further include a second heating element, which is mounted on the second housing 12. The second housing 12 mainly includes a back plate, left and right side plates, and a bottom plate. The second heating element may be disposed on the bottom plate and the left and right side plates of the second housing 12 to heat the food from the bottom of the cooking cavity in a left-right direction.

[0107] It should be noted that the first heating part and the second heating part described above can be specifically constructed as heating tubes to heat the food in the cooking cavity. Therefore, the cooking appliance 100 of this embodiment can at least have cooking functions such as steaming and baking.

[0108] In some embodiments of this application, a sealing element is provided on the door body 21. The sealing element is adapted to form a seal between the door structure and the shell assembly 1 when the door structure and the shell assembly 1 are engaged, so as to improve the sealing effect of the cooking cavity at the open opening and thereby reduce heat loss during the cooking process.

[0109] The cooking appliance 100 according to the embodiments of this application has at least the following advantages compared with the prior art:

[0110] (1) The cooking appliance 100 can adjust the volume of the cooking cavity by adjusting the relative position of the first housing 11 and the second housing 12 in the vertical direction, so that the cooking appliance 100 can meet the cooking needs of various sizes of food.
