[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] Combine Figure 1 and Figure 2 . Figure 1 is a schematic diagram of a cooking device 1, Figure 1 Schematic diagram of the door body 20 omitted. Figure 2 yes Figure 1 Schematic diagram of the partial structure of the cross section at AA in the figure. This embodiment of the present application provides a cooking device 1. The cooking device 1 provided in this embodiment of the present application can be a microwave oven, an oven, or a steamer, etc. The cooking device 1 provided in this embodiment of the present application can also be an all-in-one device that integrates the functions of any two or three of the following: a microwave oven, an oven, or a steamer.

[0025] The cooking device 1 includes a main body 30 and a door 20. The main body 30 defines a cooking cavity with at least one side open. The door 20 is mounted on the main body 30 and covers the open side of the main body 30. The cooking cavity is the area of ​​the cooking device 1 used for cooking food. Depending on the type of cooking device 1, the cooking cavity can be filled with microwaves, steam, or hot air to cook the food.

[0026] The device body 30 has an opening on one side with a mounting slot 31, within which a door seal 10 is mounted. The door seal 10 is positioned between the door 20 and the device body 30. When the door 20 is closed, it abuts against the door seal 10, sealing the gap between the door 20 and the cooking device 1. This seal prevents microwaves, steam, or hot air from leaking from the cooking cavity through the gap between the door 20 and the device body 30.

[0027] In this way, the sealing performance of the door seal 10 not only helps insulate the cooking cavity but also reduces the whistling caused by localized leakage of steam or hot air. Consequently, cooking equipment 1 is increasingly demanding the sealing performance of the door seal 10. To improve the sealing performance of the door seal 10, the specific embodiment of the door seal 10 of this application is described below.

[0028] Combine Figure 2 ,and Figure 3 , an embodiment of the present application provides a door seal 10. The door seal 10 includes a mounting portion 13, a sealing portion 11 and a connecting portion 12. The mounting portion 13 is used to be installed and matched with the device. The mounting portion 13 can be embedded, inserted or snapped into the mounting groove 31 of the device body 30. The mounting portion 13 can be installed in the mounting groove 31 by interference fit or installation with a connector. A certain pressure can exist between the mounting portion 13 and the device body 30 in the aforementioned manner to ensure good sealing performance. The mounting portion 13 can seal the gap between the door seal 10 and one side of the device body 30, thereby reducing the leakage of microwaves, steam or hot air from between the door seal 10 and the device body 30.

[0029] The sealing portion 11 is used to abut against the door body 20. When the door body 20 is closed, the door body 20 and the device body 30 apply pressure to the door seal 10, causing the door body 20 to abut against the sealing portion 11. Under the action of pressure, the sealing portion 11 can abut the door body 20 relatively tightly, thereby ensuring a good seal between the sealing member and the door body 20. The sealing portion 11 can seal the gap between the door body 20 and the door seal 10, thereby reducing the leakage of microwaves, steam, hot air, etc. between the door seal 10 and the door body 20.

[0030] The connecting portion 12 connects the mounting portion 13 and the sealing portion 11. For ease of description, the connecting portion 12 is defined as the transition portion between the mounting portion 13 and the sealing portion 11. In other embodiments, the sealing portion 11 may be directly connected to the mounting portion 13. In other words, the connecting portion 12 described herein may comprise the portion of the sealing portion 11 and the mounting portion 13 that is adjacent to and connected to each other in other embodiments.

[0031] In some embodiments, the sealing portion 11 includes a contact portion 111 and a support portion 112. The contact portion 111 is connected to the connecting portion 12 on both sides via the support portions 112. The contact portion 111 is configured to abut against the door body 20 when the door body 20 is closed, forming a seal. The support portion 112 is configured to connect the contact portion 111 to the connecting portion 12. When the door body 20 is closed, the door body 20 abuts the contact portion 111 and applies pressure, causing the contact portion 111 to move closer to the support portion 112. In this manner, the support portion 112 elastically deforms, resisting the approach of the contact portion 111. This allows the door body 20 and the contact portion 111 to abut with a certain positive pressure, thereby achieving a better sealing effect. Furthermore, when the door body 20 is closed, it can abut against the contact portion 111. Under the pressure of the door body 20, the contact portion 111 and the support portion 112 deform, thereby increasing the contact area between the contact portion 111 and the door body 20, forming a surface contact with a better sealing effect.

[0032] Furthermore, the contact portion 111, the support portion 112, and the connecting portion 12 define a first cavity 110. This cavity 110 increases the deformability and compressibility of the sealing portion 11, facilitating deformation of the contact portion 111 and the support portion 112. Consequently, under the pressure of the door body 20, the contact portion 111 can contact the door body 20 over a larger area, achieving a better seal. The provision of the first cavity 110 also reduces the overall weight of the door seal 10.

[0033] In some embodiments, the radius of curvature of the contact portion 111 is greater than the radius of curvature of the support portion 112. By setting the radius of curvature of the contact portion 111 to be greater than the radius of curvature of the support portion 112, the contact portion 111 can be made flatter than the support portion 112, thereby further increasing the contact area between the contact portion 111 and the door body 20 and further improving the sealing effect.

[0034] Optionally, the radius of curvature of the contact portion 111 is greater than 20 mm. For example, 25 mm, 30 mm or 35 mm. The radius of curvature of the contact portion 111 refers to the radius of curvature corresponding to the arc where any part of the contact portion 111 is located. The contact portion 111 can extend along the direction of the arc, and each part of the contact portion 111 has the same radius of curvature. Different parts of the contact portion 111 may also have different radii of curvature. The smallest radius of curvature of all parts of the contact portion 111 is greater than 20 mm. The contact portion 111 has a sufficient radius of curvature to enable the contact portion 111 to have a sufficiently flat surface, so that the door body 20 can form a larger contact area with the contact portion 111 when closed, so that the door seal 10 has a better sealing effect.

[0035] In some embodiments, the mounting portion 13, the sealing portion 11, and the connecting portion 12 are arranged in a first reference direction (eg, Figure 2 The two support portions 112 are arranged in a second reference direction (e.g., the Y direction in FIG. 2 ) perpendicular to the first reference direction, and the contact portion 111 connects the ends of the two support portions 112 in the second reference direction that are farther from the connection portion 12 in the first reference direction. Optionally, the door body 20 can be moved toward the device body 30 along the first reference direction to achieve closure of the door body 20. In some embodiments, the installation direction in which the mounting portion 13 enters the mounting slot 31 can also be the first reference direction.

[0036] In some embodiments, combined Figure 3, in the arrangement direction of the support portion 112, a plurality of sealing ribs 1111 are spaced apart on the side of the contact portion 111 away from the mounting portion 13. The plurality of sealing ribs 1111 are arranged to protrude toward the door body 20 relative to the contact portion 111. When the door body 20 is closed, the plurality of sealing ribs 1111 can form multiple seals with the door body 20, thereby improving the sealing effect. Among them, the door seals 10 in the related art are all formed by extrusion. In addition, since the door seal 10 needs to be arranged in a ring shape around the equipment main body 30, the flatness and uniformity of the contact portion 111 may be unsatisfactory during the production and use process of the contact portion 111, which may cause the contact between the contact portion 111 and the door body 20 to be unsatisfactory or even partially unable to contact. Providing a sealing rib 1111 on the contact portion 111 allows the sealing rib 1111 to contact the door body 20 in a manner that is raised relative to the contact portion 111, thereby compensating for the problem of poor contact between the contact portion 111 and the door body 20 when the flatness and uniformity of the contact portion 111 are not ideal. The sealing rib 1111 can further ensure that the door seal 10 can fully contact the door body 20, thereby achieving the desired sealing effect.

[0037] On the other hand, the material of the door body 20 can be glass, metal, etc. If the contact portion 111 contacts the door body 20 in a completely flat and uniform manner, it may cause the contact portion 111 to adhere to the door body 20. By providing a protruding sealing rib 1111, the shape and pressure of the base of the door seal 10 and the door body 20 can change at the location of the sealing rib 1111. This can generate stress concentration in the area near the sealing rib 1111 when the door body 20 is opened, thereby improving the technical problem of adhesion between the door body 20 and the door seal 10.

[0038] Combine Figure 5 In an embodiment of the present application, a door seal 10 is provided. The door seal 10 includes a mounting portion 13, a sealing portion 11, and a connecting portion 12. The mounting portion 13 is used for mounting and cooperating with a device. The sealing portion 11 is used for abutting against the door body 20. The connecting portion 12 connects the mounting portion 13 and the sealing portion 11. The sealing portion 11 and the connecting portion 12 enclose a first cavity 110. An abutting member 14 may be provided in the first cavity 110.

[0039] The mounting portion 13 is used for installation with the device. The mounting portion 13 can be embedded, inserted, or snapped into the mounting slot 31 of the device body 30. The mounting portion 13 can be installed in the mounting slot 31 by means of an interference fit or by means of a connector. A certain pressure can exist between the mounting portion 13 and the device body 30 to ensure a good sealing performance. The mounting portion 13 can seal the gap between the door seal 10 and one side of the device body 30, thereby reducing the leakage of microwaves, steam, or hot air between the door seal 10 and the device body 30.

[0040] The sealing portion 11 is used to abut against the door body 20. When the door body 20 is closed, the door body 20 and the device body 30 apply pressure to the door seal 10, causing the door body 20 to abut against the sealing portion 11. Under the action of pressure, the sealing portion 11 can abut the door body 20 relatively tightly, thereby ensuring a good seal between the sealing member and the door body 20. The sealing portion 11 can seal the gap between the door body 20 and the door seal 10, thereby reducing the leakage of microwaves, steam, hot air, etc. between the door seal 10 and the door body 20.

[0041] The connecting portion 12 connects the mounting portion 13 and the sealing portion 11. For ease of description, the connecting portion 12 is defined as the transition portion between the mounting portion 13 and the sealing portion 11. In other embodiments, the sealing portion 11 may be directly connected to the mounting portion 13. In other words, the connecting portion 12 described herein may comprise the portion of the sealing portion 11 and the mounting portion 13 that is adjacent to and connected to each other in other embodiments.

[0042] The sealing portion 11 and the connecting portion 12 define a first cavity 110 , which allows the sealing portion 11 to deform under pressure from the door 20 , thereby increasing the contact area between the sealing portion 11 and the door 20 .

[0043] Under the pressure of the door body 20 , the sealing portion 11 may come into contact with the connecting portion 12 , and adhesion may occur. To improve this situation, an abutment member 14 is provided in the first cavity 110 , and the abutment member 14 is sandwiched between the sealing portion 11 and the connecting portion 12 .

[0044] Specifically, an abutment 14 can be provided in the first cavity 110. On the one hand, the abutment 14 can reduce the direct contact between the sealing portion 11 and the connecting portion 12, destroying the uniform pressure distribution in the first cavity 110, so that during the elastic recovery process of the contact portion 111, the stress between the connecting portion 12 and the abutment 14 can produce local stress concentration at the abutment 14, reducing the obstruction of the rebound of the sealing portion 11. In this way, the adhesion between the sealing portion 11 and the connecting portion 12, or the sealing portion 11 and the abutment 14, can be reduced. The abutment 14 can also provide a certain supporting force for the sealing portion 11, so that sufficient pressure can be maintained between the sealing portion 11 and the door body 20 to ensure a sufficient sealing effect.

[0045] In some embodiments, the sealing portion 11 and the connecting portion 12 are made of the same or similar organic materials, such as rubber or plastic. This can cause the contact portion 111 and the connecting portion 12 to slightly fuse under pressure, which can easily lead to adhesion. To improve this, the abutment member 14 can be made of a material that is significantly different from that of the sealing portion 11 and the connecting portion 12, such as a metal, ceramic, or other inorganic material.

[0046] In some embodiments, the sealing portion 11 includes a contact portion 111 and a support portion 112, and both sides of the contact portion 111 are connected to the connecting portion 12 through the support portion 112. The contact portion 111 is used to abut against the door body 20 when the door body 20 is closed to form a seal. The support portion 112 is used to connect the contact portion 111 with the connecting portion 12. The contact portion 111, the support portion 112 and the connecting portion 12 are arranged to form a first cavity 110, and the abutment member 14 is arranged in the first cavity 110 and is clamped between the contact portion 111 and the connecting portion 12. Specifically, the abutment member 14 can reduce the adhesion between the contact portion 111 and the connecting portion 12 in the above manner.

[0047] The abutment member 14 can exist in different forms within the first cavity 110. The following describes different embodiments of the abutment member 14. The different embodiments of the abutment member 14 can be combined with one another. It is understood that, if the embodiments are not mutually exclusive, solutions obtained by combining the following embodiments are also within the scope of protection of this application.

[0048] Combine Figure 5 In some embodiments, the abutting member 14 is a abutting protrusion. The abutting protrusion can be connected to the contact portion 111 or the connecting portion 12 by a connector or adhesive. The abutting protrusion can also be integrally formed with the contact portion 111 or the connecting portion 12.

[0049] In some embodiments, at least one abutting protrusion is provided on the side of the contact portion 111 facing the mounting portion 13. When the contact portion 111 moves toward the connecting portion 12, the abutting protrusion can abut against the connecting portion 12, thereby reducing the adhesion problem between the contact portion 111 and the connecting portion 12.

[0050] Furthermore, in some embodiments, at least two abutment protrusions are provided on the side of the contact portion 111 facing the mounting portion 13, and the abutment protrusions are spaced apart in the arrangement direction (i.e., the second reference direction) of the support portions 112. In this way, the problem of adhesion between the contact portion 111 and the connecting portion 12 can be further reduced.

[0051] In some embodiments, at least one abutting protrusion is provided on the side of the connecting portion 12 facing the contact portion 111. When the contact portion 111 moves toward the connecting portion 12, the abutting protrusion can abut against the contact portion 111, thereby reducing the adhesion problem between the contact portion 111 and the connecting portion 12.

[0052] In some embodiments, at least two abutment protrusions are provided on the side of the connecting portion 12 facing the contact portion 111. The abutment protrusions are spaced apart in the arrangement direction of the support portions 112. The abutment protrusions are spaced apart in the arrangement direction of the support portions 112 (i.e., the second reference direction). In this way, the problem of adhesion between the contact portion 111 and the connecting portion 12 can be further reduced.

[0053] In some embodiments, at least two abutting protrusions are provided, and the at least two abutting protrusions are integrally formed with the contact portion 111 and the connecting portion 12. That is, the side of the contact portion 111 facing the connecting portion 12 is provided with an abutting protrusion, and the side of the connecting portion 12 facing the contact portion 111 is provided with an abutting protrusion. The two abutting protrusions, by being sandwiched between the contact portion 111 and the connecting portion 12, change the contact area and pressure distribution between the contact portion 111 and the connecting portion 12 under pressure, thereby achieving the aforementioned technical effect of preventing adhesion.

[0054] Furthermore, the aforementioned at least two abutment protrusions are provided in correspondence. Specifically, the projection of the abutment protrusion provided on the connecting portion 12 in the first reference direction coincides with the projection of the abutment protrusion provided on the contact portion 111 in the first reference direction. In other words, when the abutment portion deforms and approaches the connecting portion 12, the two abutment protrusions abut against each other. In this way, when the contact portion 111 approaches the connecting portion 12, the abutment of the two abutment protrusions can create a larger gap between the contact portion 111 and the connecting portion 12, thereby further achieving the technical effect of preventing adhesion.

[0055] In other embodiments, the abutting member 14 may be a separate part from the sealing portion 11 and the connecting portion 12. The abutting member 14 may extend into the first cavity 110, thereby achieving the aforementioned technical effect of preventing adhesion.

[0056] Combine Figure 6 and Figure 7 In some embodiments, at least one supporting rib 15 is provided between the contact portion 111 and the connecting portion 12, and the supporting rib 15 connects the sealing portion 11 and the connecting portion 12. The extending direction of the supporting rib 15 is consistent with the arrangement direction of the sealing portion 11 and the mounting portion 13. On the one hand, the supporting rib 15 will space the connecting portion 12 and the contact portion 111, thereby preventing the contact portion 111 and the connecting portion 12 from adhering to each other. On the other hand, the supporting rib 15 can support the contact portion 111 when the contact portion 111 tends to move closer to the connecting portion 12, thereby increasing the pressure between the contact portion 111 and the door body 20 when the door body 20 is closed, thereby further optimizing the sealing effect.

[0057] In some embodiments, the thickness of the support portion 112 is greater than the thickness of the contact portion 111. The contact portion 111 is used to contact the door body 20. The support portion 112 is used to support the contact portion 111, thereby generating pressure between the contact portion 111 and the door body 20, thereby achieving a sealing effect. By setting the thickness of the support portion 112 to be greater than the thickness of the contact portion 111, the support portion 112 can provide more sufficient support force, thereby generating a greater positive pressure when the contact portion 111 contacts the door body 20, further improving the sealing effect.

[0058] In some embodiments, the door seal 10 is annular and arranged around the opening of the device body 30 , thereby preventing microwaves, steam or hot air from leaking from the circumference when the door body 20 is closed, thereby achieving a good sealing effect.

[0059] In some embodiments, combined Figure 4 The sealing portion 11 is provided with an exhaust hole 113 that is in communication with the interior of the sealing portion 11. The exhaust hole 113 is in communication with the first cavity 110. The exhaust hole 113 can discharge the gas in the first cavity 110 when the sealing portion 11 is compressed or expanded due to heat, thereby reducing the occurrence of poor sealing. Optionally, the intervals between the exhaust holes 113 are greater than or equal to one-quarter of the total circumference of the door seal 10, so that the exhaust rate of the exhaust holes 113 is small while satisfying the exhaust function. In this way, when the door body 20 is closed, the door seal 10 can play a sufficient buffering role.

[0060] In some embodiments, combined Figures 2 to 7 As shown in any of the accompanying drawings, the mounting portion 13 is hollow, forming a second cavity 130. The second cavity 130 can increase the variability and compressibility of the mounting portion 13, facilitating the assembly of the mounting portion 13 within the mounting groove 31. Teeth 131 are provided on opposite sides of the mounting portion 13, extending obliquely from the mounting portion 13 toward the sealing portion 11. Multiple teeth 131 are spaced apart in the first reference direction. The provision of the teeth 131 enables multiple seals to be formed between the mounting portion 13 and the mounting groove 31, increasing the contact area with the mounting groove 31 and thereby improving the sealing performance between the mounting portion 13 and the mounting groove 31. The teeth 131 themselves are easily deformed, and the relative protrusion of multiple teeth 131 can also provide a certain amount of interference fit for easy deformation and assembly, thereby improving the installation stability of the mounting portion 13. The ends of the mounting portion 13 can also be provided with clearance grooves to make way for fasteners such as screws or rivets on the device body 30. The mounting portion 13 may also be provided in a communicating hole communicating with the second cavity 130 , so that when the door seal 10 expands due to heat, the total amount of expansion can be reduced by discharging gas from the second cavity 130 , thereby ensuring sealing stability.

[0061] In some embodiments, a first water retaining portion 121 and a second water retaining portion 122 are further provided on opposite sides of the connecting portion 12. The first water retaining portion 121 extends from the connecting portion 12 along the sealing portion 11 toward the mounting portion 13 and is spaced apart from the mounting portion 13. The second water retaining portion 122 extends from the connecting portion 12 along the spacing between the two support portions 112. Furthermore, the first water retaining portion 121 is located on the side of the connecting portion 12 away from the opening of the device body 30, while the second water retaining portion 122 is located on the side of the connecting portion 12 closer to the opening of the device body 30. Optionally, the first water retaining portion 121 extends from the opening into the cooking cavity of the device body 30.

[0062] The first water retaining portion 121 allows condensed water to flow back into the cooking cavity through the first water retaining portion 121, thereby preventing condensed water and hot steam from flowing into the mounting groove 31 and causing corrosion to the mounting groove 31. The second water retaining portion 122 shields the side of the mounting groove 31 away from the opening, thereby further preventing condensed water or external splashing water from entering the mounting groove 31 and reducing the possibility of corrosion of the mounting groove 31.

[0063] The above are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
