Description

Technical Field

[0001] This application relates to the field of cooking equipment technology, and in particular to a door assembly and cooking equipment. Background Technology

[0002] A microwave-steam-grill combo combines the functions of a microwave oven, steamer, and oven, enabling multiple cooking tasks such as steaming, grilling, frying, and microwaving within a single cooking cavity. The door is the core safety component of the combo, requiring consideration of factors such as preventing steam and microwave leaks, heat dissipation, durability, and ease of maintenance.

[0003] In related technologies, the door body includes an outer glass, a middle glass, an inner glass, a left support, and a right support. The left and right supports are symmetrical and fixed on the outer glass. One of the left and right supports has a stepped surface on the side facing the other. The inner glass is fixed on the stepped surface so that the stepped surface provides a supporting foundation for the inner glass. The middle glass is fixed between the inner glass and the outer glass.

[0004] However, in related technologies, due to manufacturing errors in the step area on the left and right supports, the flatness of the step surface is poor. When the inner glass is assembled on the step surface, the flatness is poor, which leads to a gap between the inner glass and the door sealing strip, resulting in air leakage. Utility Model Content

[0005] In view of the above problems, this application provides a door assembly and cooking device to solve the problem of air leakage caused by poor flatness of the inner glass after assembly.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] The first aspect of this application provides a door assembly, including:

[0008] First phylum;

[0009] Two first supports are symmetrically distributed on both sides of the door body along a first direction, and each extends along the corresponding side of the first door body. Both first supports have stepped surfaces on their adjacent inner sides.

[0010] At least two first support members are respectively disposed on the step surface of two first brackets, and at least one first support member is disposed on one step surface, and each first support member has a first support surface;

[0011] Two second support members are respectively disposed at the ends of the two first brackets, one second support member corresponds to one first bracket, and each second support member has a second support surface, wherein the sum of the areas of the first support surface and the second support surface is less than the area of ​​the step surface;

[0012] The second door body is disposed on the first support surface and the second support surface, and is respectively attached to the first support surface and the second support surface.

[0013] The door assembly provided in this application embodiment includes at least two first support members and two second support members. The two first support members are respectively disposed on the stepped surfaces of two first brackets, and the two second support members are respectively disposed at the ends of two first brackets. Each first support member has a first support surface, and each second support member has a second support surface. The sum of the areas of the first and second support surfaces is smaller than the area of ​​the stepped surface. The second door body is disposed on the first and second support surfaces and is in contact with them. This reduces the support area used to support the second door body, thereby reducing the impact of the flatness of the support surfaces on the second door body, ensuring the surface flatness of the second door body, and avoiding air leakage caused by poor surface flatness of the second door body.

[0014] In some embodiments, the first support is disposed at the end of the stepped surface away from the second support, and the second support surface is at least partially located on the extension path of the first support surface.

[0015] This improves the stability of the support for the second door.

[0016] In some embodiments, when the second door body is disposed on the first support surface and the second support surface, the first support surface is flush with the second support surface.

[0017] This improves the flatness of the second door, thus solving the problem of air leakage due to gaps.

[0018] In some embodiments, the first support member is an elastic support member.

[0019] In this way, because the first support is elastic, it can offset the deformation of a portion of the second door body after assembly, thereby ensuring the surface flatness of the second door body and solving the problem of air leakage.

[0020] In some embodiments, the second support member has a support portion and an elastic portion, the elastic portion being disposed on the support portion, and the surface of the elastic portion facing away from the support portion being formed as the second support surface.

[0021] In this way, the elastic portion can also offset the deformation of a portion of the second door body after assembly, thereby further improving the flatness of the second door body and further solving the air leakage problem. In some embodiments, the first support member has a first limiting portion, and the second support member has a second limiting portion. When the second door body is disposed on the first support surface and the second support surface, the second door body is limited between the first limiting portion and the second limiting portion along the second direction, wherein the second direction has an angle with the first direction.

[0022] In this way, the second door can be limited and fixed in the second direction.

[0023] In some embodiments, the first limiting portion is an elastic limiting pad.

[0024] By setting the first limiting part as an elastic limiting pad, sufficient expansion and contraction space can be provided for the second door body in the second direction, thereby reducing the spontaneous explosion rate of the second door body due to thermal expansion.

[0025] In some embodiments, the door assembly further includes a stop member that abuts against the side of the first limiting portion opposite to the second door body and is connected to the first bracket.

[0026] In this way, the abutment provides support to the first limiting part, thereby improving the stability and reliability of the first limiting part in limiting and fixing the second door body in the second direction.

[0027] In some embodiments, the abutment has an abutment portion and a fixing portion. The abutment portion is configured to be disposed on the side of the first limiting portion away from the second door body and abut against the first limiting portion. The fixing portion is configured to be at least partially disposed on the step surface and fixedly connected to the first bracket.

[0028] This improves the reliability of the connection between the blocking component and the first bracket, as well as the reliability of the support for the first limiting part, thereby further improving the stability and reliability of the second door body in the second direction for upper limit and fixation.

[0029] In some embodiments, the door assembly further includes a second bracket, which is disposed at one end of the two first brackets opposite to the corresponding second support member, and is connected to the two first brackets respectively;

[0030] The second bracket has a first limiting structure, and the second support member has a second limiting structure. Along a third direction, one end of the second door is limited between the first limiting structure and the first support surface, and the other end of the second door is limited between the second limiting structure and the second support surface; wherein, the third direction is the thickness direction of the second door.

[0031] In this way, the second door can be limited and fixed in the third direction.

[0032] In some embodiments, the first limiting structure is at least one of a limiting rib, a limiting protrusion, or a limiting plate; and / or,

[0033] The second support member has a limiting groove that opens toward one side of the first support member. The limiting groove has a first groove wall, a second groove wall, and a third groove wall. The first groove wall and the third groove wall are arranged opposite to each other in the second direction. The second groove wall is connected between the first groove wall and the third groove wall. The first groove wall is formed as the second support surface, the third groove wall is formed as the second limiting structure, and the second groove wall is formed as the second limiting part.

[0034] This ensures the stability and reliability of the third door's position, and the structure is simple, easy to implement, and low in cost.

[0035] In some embodiments, the door assembly further includes a third door located between the first door and the second door, wherein the first support member has a first slot opening toward one side of the second support member, the second support member has a second slot opening toward one side of the first support member, a portion of the structure at one end of the third door is located in the first slot, and a portion of the structure at the other end of the third door is located in the second slot.

[0036] This improves the reliability and stability of the third door installation location.

[0037] A second aspect of this application provides a cooking device, including the door assembly provided in the first aspect above.

[0038] The cooking device provided in this application embodiment has the same beneficial effects as the door assembly provided in the above embodiment, and will not be described again here.

[0039] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the door components and cooking equipment provided by the embodiments of this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation.

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0064] This application provides a cooking device, which includes, but is not limited to, a microwave-steam-grill combo. Taking a microwave-steam-grill combo as an example, the cooking device includes a device body and a door assembly. The device body has a cooking cavity with one side open, which is used to hold food to be cooked. The door assembly is movably disposed at the open side to close or open the cooking cavity, thereby facilitating the user to take out and put in food. Since the door assembly is the core safety component of the microwave-steam-grill combo, it must take into account factors such as preventing steam and microwave leakage, heat dissipation, durability, and ease of maintenance.

[0065] The structure of the door assembly will be described in detail below with reference to the accompanying drawings. It should be noted that in this article, the orientation of each component in the door assembly is described with the door assembly in the closed state.

[0066] Please refer to Figures 1 to 5As shown, the door assembly 10 provided in this embodiment includes a first door 100, two first supports 200, and a second door 500, wherein the two first supports 200 are along the width direction of the first door 100 (e.g., ...). Figure 1 The two first supports 200 are symmetrically arranged on the inner surface of the first door assembly 100 (in the left-right direction). The inner surface of the first door assembly 100 is, for example, the surface facing the cooking cavity. Both first supports 200 extend in the height direction of the door assembly 10, that is, the two first supports 200 are located on both sides of the first door assembly 100 along the first direction, and each extends along the extension direction of the first door assembly 100 and its corresponding side. For example, when the door assembly 10 is placed vertically, the first supports 200 extend in, for example, the vertical direction. Both of the first supports 200 have a stepped surface 210 on the side facing the other. That is, both first supports 200 have stepped surfaces 210 on their inner sides that are close to or adjacent to each other. The stepped surface 210 is a long strip-shaped stepped surface 210 that extends vertically and has a large area. When the door is assembled, the two first supports 200 are fixed to the first door 100 by means of adhesive or other methods. The second door 500 is placed on the stepped surfaces 210 of the two supports so that the stepped surfaces 210 provide a supporting foundation for the second door 500.

[0067] like Figure 2 , Figure 4 and Figure 5 As shown, the first bracket 200 includes, but is not limited to, being fixed to the inner surface of the first door body 100 by means of adhesive or other methods. For example, the inner surface of the first door body 100 faces the cooking cavity. In addition, the two first brackets 200 have overflow holes on the side facing the first door body 100. In this way, when the first bracket 200 is bonded to the first door body 100 by adhesive, the overflow holes can be used to accommodate excess glue, so as to prevent the problem of excessive accumulation of excess glue in the bonding area and overflow. It also helps to ensure that the glue is evenly distributed on the bonding surface and improves the bonding reliability.

[0068] In addition, such as Figure 2 and Figure 5As shown, the door assembly 10 also includes two second support members 400 and a second bracket 600. The two second support members 400 are respectively installed at the ends of the two first brackets 200 and fixedly connected to the first brackets 200. One second support member 400 corresponds to one first bracket 200, and the second support member 400 faces the second slot 450 which opens towards the first bracket 200. When the second door 500 is disposed on the stepped surface 210, a portion of the structure of the second door 500 facing the second support member 400 is inserted into the second slot 450. The bracket 600 is disposed at one end of the two first brackets 200 away from the second support member 400 and is fixedly connected to the first brackets 200. For example, the second support member 400 is fixedly connected to the bottom end of the first bracket 200 by screws, and the second bracket 600 is disposed at the top end of the two first brackets 200. The two ends of the second bracket 600 are respectively fixedly connected to the two first brackets 200 by screws or other fasteners. In this way, the two second support members 400 and the second bracket 600 together limit and fix the second door 500 in the vertical direction.

[0069] The first door 100 and the second door 500 include, but are not limited to, high-temperature resistant glass doors. In this article, we will take a door where both the first door 100 and the second door 500 are made of glass as an example.

[0070] like Figure 2 As can be seen, the use of a large-area stepped surface 210 to provide a supporting foundation for the second door 500 requires a high degree of flatness. However, during production, there are manufacturing errors in the stepped surface 210, resulting in unevenness. This leads to poor flatness of the assembled second door 500. Poor flatness of the second door 500 causes gaps between the second door 500 and the sealing strip at the opening of the cooking cavity, resulting in poor sealing of the cooking cavity and air leakage. This affects the overall performance of the cooking equipment and the cooking effect. On the other hand... During the assembly of the door body, one end of the second door body 500 is engaged in the second slot 450 on the second support member 400. The step surface 210 itself has manufacturing errors, resulting in poor flatness of the assembled second door body 500. At this time, when the end of the second door body 500 is located in the second slot 450, there are further assembly errors between the second support member 400 and the second bracket 600. Thus, there may be a compressive stress between the second door body 500 and the groove wall of the second slot 450. When used in a high-temperature environment, the second door body 500 is at risk of bursting due to thermal expansion.

[0071] To address the aforementioned issues, this application provides a door assembly 10, which aims to improve the flatness of the second door 500 after installation, thereby enhancing the overall performance and cooking effect of the cooking equipment. On the other hand, it provides sufficient expansion and contraction space to the second door 500 in the vertical direction, reducing the self-explosion rate of the second door 500 due to thermal expansion within the second slot 450.

[0072] The door assembly 10 provided in the embodiments of this application will be further described below with reference to the accompanying drawings, based on the above embodiments.

[0073] Please refer to Figures 6 to 12 As shown, the door assembly 10 provided in this application embodiment further includes at least two first support members 300. The at least two first support members 300 are respectively disposed on the step surface 210 of the two first brackets 200. At least one first support member 300 is disposed on one step surface 210. Each first support member 300 has a first support surface 310. In addition, each of the two second support members 400 is provided with a second support surface 410. Ideally, the first support surface 310 and the second support surface 410 are located on the same plane, that is, the first support surface 310 and the second support surface 410 are flush. The first support surface 310 and the second support surface 410 together provide a support base for the second door 500. When the second door 500 is disposed on the first support surface 310 and the second support surface 410, the second door 500 is in contact with the first support surface 310 and the second support surface 410 respectively.

[0074] It should be noted that the first support surface 310 and the second support surface 410 are located on the same plane (i.e., flush). This means that the error of the first support surface 310 and the second support surface 410 is within the allowable error range of the flatness after the second door body 500 is installed. In this way, when the first support surface 310 and the second support surface 410 provide a support base for the second door body 500, the flatness of the second door body 500 after assembly will not cause air leakage. That is, the flatness of the second door body 500 is within the allowable and qualified error range.

[0075] Among them, such as Figure 7 and Figure 11As shown, the areas of the first support surface 310 and the second support surface 410 are both smaller than the area of ​​the step surface 210, and the sum of the areas of the first support surface 310 and the second support surface 410 is also smaller than the area of ​​the step surface 210. In this way, the contact area between the first door body 100 and the first support surface 310 and the second support surface 410 can be reduced. By reducing the contact area with the second door body 500, the flatness of the second door body 500 after assembly can be reduced due to the flatness error of the first support surface 310 and the second support surface 410. This can solve the problem of steam leakage caused by the flatness of the second door body 500, improve the sealing of the cooking cavity in the cooking equipment, and improve the overall performance and cooking effect of the cooking equipment.

[0076] For example, the first support member 300 can be fixedly installed on the step surface 210 by means of adhesive, snap-fit, magnetic attraction, etc. In addition, the first support surface 310 and the second support surface 410 are planes that match the surface of the second door body 500, so as to improve the support stability, reliability and flatness of the second door body 500.

[0077] It is understandable that the areas of the first support surface 310 and the second support surface 410 are small. Therefore, the contact area between the first support surface 310 and the second support surface 410 and the second door body 500 is small when used to support the second door body 500. In this way, the influence of the first support surface 310 and the second support surface 410 on the flatness of the second door body 500 after assembly can be reduced.

[0078] like Figure 7 As shown, each step surface 210 is provided with a first support member 300, and the first support member 300 is located at the end of the corresponding step surface 210 away from the second support member 400. The second support surface 410 is at least partially located on the extension path of the first support surface 310. In this way, the first support surfaces 310 on the two first support members 300 and the second support surfaces 410 on the two second support members 400 are arranged in a rectangular array to support the four corners of the second door body 500, that is, to form a four-point support, so as to improve the stability of the support for the second door body 500.

[0079] In some embodiments, the first support member 300 is an elastic support member. Since the first support member 300 is elastic, it can be adjusted according to the deformation of the second door body 500 after assembly. For example, it can offset part of the deformation of the second door body 500 after assembly, thereby improving the flatness of the second door body 500 through assembly and thus solving the problem of steam leakage.

[0080] To further improve the flatness of the second door 500, in some embodiments, when the first support member 300 is in a free state, the first support surface 310 is higher than the second support surface 410, and the height difference between the first support surface 310 and the second support surface 410 is less than or equal to the deformation of the first support member 300 in the height direction. When the second door 500 is disposed on the first support surface 310 and the second support surface 410, the first support surface 310 and the second support surface 410 are flush. In this way, the elastic deformation of the first support member 300 can offset the deformation of a portion of the second door 500 after assembly, thereby further improving the flatness of the second door 500 and solving the problem of air leakage.

[0081] For example, the first support member 300 includes, but is not limited to, an elastic support member made of elastic materials such as rubber and silicone. The first support member 300 can be a block or columnar structure. For example, the first support member 300 can be any shape with a cross-section such as a circle, rectangle or polygon, as long as it can improve the support stability and flatness of the second door 500. No specific restrictions are imposed here.

[0082] like Figure 11 As shown, the cross-sectional profile of the first support member 300 is a rectangular block structure, and the first support surface 310 is a rectangular support surface.

[0083] To further improve the flatness of the second door 500 after assembly, and to avoid the risk of stress concentration and cracking of the second door 500 at high temperatures after assembly, in some embodiments, the second support member 400 has a support portion and an elastic portion. The elastic portion is disposed on the support portion, and the surface of the elastic portion facing away from the support portion is formed as the second support surface 410. In this way, the elastic portion can also offset the deformation of some areas of the second door 500 after assembly, thereby further improving the flatness of the second door 500 and solving the problem of air leakage.

[0084] For example, the elastic part includes, but is not limited to, being an integral structure with the support part. For instance, the elastic part can also be provided on the support part by means of adhesion, magnetic attraction, or snap-fit, etc., without any specific limitation.

[0085] Please refer to Figure 10 and Figure 11As shown, the first support member 300 has a first limiting part 320, and the second support member 400 has a second limiting part 430. When the second door body 500 is disposed on the first support surface 310 and the second support surface 410, the second door body 500 is limited between the first limiting part 320 and the second limiting part 430 along the second direction. The second direction has an angle with the first direction. For example, the second direction is the up-down direction (i.e., the vertical direction) of the door assembly 10 when it is closed. In this way, the first limiting part 320 and the second limiting part 430 can jointly limit and fix the second door body 500 in the second direction.

[0086] For example, the first limiting part 320 includes, but is not limited to, an elastic limiting pad made of elastic material such as silicone or rubber. Since the first limiting part 320 has good elasticity, the upper limit of the second door 500 in the second direction is located between the first limiting part 320 and the second limiting part 430. In this way, the elasticity of the first limiting part 320 allows the second door 500 to have a certain amount of expansion and contraction space in the second direction, thereby reducing the self-explosion rate of the second door 500 due to thermal expansion and thus improving the safety and reliability of the second door 500.

[0087] Please refer to Figure 7 , Figure 10 and Figure 12 As shown, the door assembly 10 also includes a stop member 700. Along the second direction, the stop member 700 abuts against the side of the first limiting part 320 opposite to the second door body 500 and is connected to the first bracket 200. In this way, the stop member 700 provides support for the first limiting part 320, thereby improving the stability and reliability of the first limiting part 320 in limiting and fixing the second door body 500 in the second direction.

[0088] Please continue to refer to Figure 7 , Figure 10 and Figure 12 As shown, the blocking member 700 has a blocking part 710 and a fixing part 720. The blocking part 710 is configured to be disposed on the side of the first limiting part 320 away from the second door body 500 and abut against the first limiting part 320. The fixing part 720 is configured to be at least partially disposed on the step surface 210 and fixedly connected to the first bracket 200. In this way, the connection reliability between the blocking member 700 and the first bracket 200, as well as the support reliability of the first limiting part 320, can be improved, thereby further improving the stability and reliability of the second door body 500 in the second direction for upper limit and fixation.

[0089] For example, the blocking part 710 is a blocking plate or blocking block arranged parallel to the first limiting part 320, and the fixing part 720 is a fixing plate or fixing block, such as Figure 7As shown, the blocking part 710 and the fixing part 720 form an "L" shaped structure. In this way, the blocking part 710 fits against the first limiting part 320, and the fixing part 720 is disposed on the stepped surface 210 of the first bracket 200 and fits against the stepped surface 210. The fixing part 720 has a through hole through which a screw can pass. Correspondingly, the stepped surface 210 has a screw hole that matches the screw. The screw passes through the through hole on the fixing part 720 and is threadedly connected to the screw hole on the stepped surface 210, thereby realizing the fixed connection between the blocking part 700 and the first bracket 200.

[0090] Please refer to Figures 6 to 8 , Figure 10 As shown, the second bracket 600 has a first limiting structure 610, and the second support member 400 has a second limiting structure 420. Along the third direction, one end of the second door body 500 is limited between the first limiting structure 610 and the first support surface 310, and the other end of the second door body 500 is limited between the second limiting structure 420 and the second support surface 410. The third direction is the thickness direction of the second door body 500 (e.g., the front-back direction of the door assembly 10). In this way, the second door body 500 can be limited and fixed in the third direction.
