[0024] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0025] In combination with Figure 1 and Figure 2 . Figure 1 is a schematic view of a cooking apparatus 1, Figure 1 is a schematic view of a door body 20 omitted in the embodiment. Figure 2 is Figure 1 is a schematic view of a partial structure in cross section at A-A. The present application provides a cooking apparatus 1. The cooking apparatus 1 provided by the embodiments of the present application can be a microwave oven, an oven or a steamer. The cooking apparatus 1 provided by the embodiments of the present application can also be a combination of any two or all of the functions of a microwave oven, an oven and a steamer.

[0026] The cooking apparatus 1 comprises an apparatus body 30 and a door body 20. The apparatus body 30 has a cooking cavity with at least one open side. The door body 20 is installed on the apparatus body 30, and is used to cover the side of the apparatus body 30 with the opening. The cooking cavity is a region for cooking food in the cooking apparatus 1. Depending on the type of the cooking apparatus 1, microwaves, steam or hot air can be filled in the cooking cavity to cook food.

[0027] The side of the apparatus body 30 with the opening is provided with a mounting groove 31, and the door seal 10 is mounted in the mounting groove 31. The door seal 10 is arranged between the door body 20 and the apparatus body 30. When the door body 20 is closed, the door body 20 can abut against the door seal 10, thereby sealing the gap between the door body 20 and the cooking apparatus 1. The door seal 10 can play a sealing role, thereby preventing microwaves, steam or hot air in the cooking cavity from leaking from the gap between the door body 20 and the apparatus body 30.

[0028] In this way, the sealing performance of the door seal 10 can on the one hand play a heat preservation role on the cooking cavity. The sealing performance of the door seal 10 can on the other hand reduce the howling phenomenon caused by the leakage of steam or hot air from the local. On this basis, the cooking equipment 1 has higher and higher requirements for the sealing performance of the door seal 10. In order to improve the sealing performance of the door seal 10, the specific embodiments of the door seal 10 of the present application can refer to the following description.

[0029] In combination with Figure 2 , and Figure 3 , the embodiments of the present application provide 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 for mounting cooperation with the equipment. The mounting portion 13 can be embedded, inserted or clamped in the mounting groove 31 of the equipment body 30. The mounting portion 13 mounted in the mounting groove 31 can be mounted by interference fit or connecting piece, etc. There can be a certain pressure between the mounting portion 13 and the equipment body 30 by the above-mentioned way, so as to ensure good sealing performance. The mounting portion 13 can seal the gap between the door seal 10 and one side of the equipment body 30, thereby reducing the leakage of microwaves, steam or hot air, etc. from between the door seal 10 and the equipment body 30.

[0030] The sealing portion 11 is used for abutting against the door body 20. In the case of closing the door body 20, the door body 20 and the equipment body 30 will exert pressure on the door seal 10, and the door body 20 can abut against the sealing portion 11. The sealing portion 11 can abut against the door body 20 more closely under the action of the pressure, so as to ensure that the sealing member has good sealing between 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 or hot air, etc. from between the door seal 10 and the door body 20.

[0031] The connecting portion 12 can connect the mounting portion 13 and the sealing portion 11. In the description of the present application, in order to facilitate the description, the transition part between the mounting portion 13 and the sealing portion 11 is defined as the connecting portion 12. While in other embodiments, the sealing portion 11 can be directly connected with the mounting portion 13. In other words, the connecting portion 12 of the present application can be composed of the part where the sealing portion 11 and the mounting portion 13 are close to each other and connected in other embodiments.

[0032] In some embodiments, the sealing part 11 comprises a contact part 111 and a support part 112, and the two sides of the contact part 111 are connected to the connecting part 12 through the support part 112 respectively. The contact part 111 is used to abut against the door body 20 to form a seal when the door body 20 is closed. The support part 112 is used to connect the contact part 111 to the connecting part 12. When the door body 20 is closed, the door body 20 abuts against the contact part 111 and exerts a pressure, so that the contact part 111 tends to move close to the support part 112. In this case, the support part 112 will be elastically deformed to resist the movement of the contact part 111. In this way, the door body 20 and the contact part 111 can abut against each other with a certain positive pressure, thereby achieving a better sealing effect. On the other hand, the door body 20 can abut against the contact part 111 when it is closed. Under the pressure of the door body 20, the contact part 111 and the support part 112 will be deformed, thereby increasing the contact area between the contact part 111 and the door body 20, forming a better surface contact.

[0033] Further, the contact part 111, the support part 112 and the connecting part 12 surround a first cavity 110. The first cavity 110 surrounded by the contact part 111, the support part 112 and the connecting part 12 can increase the deformability and compressibility of the sealing part 11, facilitate the deformation of the contact part 111 and the support part 112, so that the contact part 111 can abut against the door body 20 with a larger area under the pressure of the door body 20, thereby achieving a better sealing effect. The setting of the first cavity 110 can also reduce the overall weight of the door seal 10.

[0034] In some embodiments, the radius of curvature of the contact part 111 is greater than the radius of curvature of the support part 112. By setting the radius of curvature of the contact part 111 to be greater than the radius of curvature of the support part 112, the contact part 111 can be flatter than the support part 112, thereby further increasing the contact area between the contact part 111 and the door body 20 and further improving the sealing effect.

[0035] Optionally, the radius of curvature of the contact part 111 is greater than 20 mm, for example, 25 mm, 30 mm or 35 mm. The radius of curvature of the contact part 111 refers to the radius of curvature corresponding to the arc line where any part of the contact part 111 is located. The contact part 111 can extend along the direction of a circular arc, and each part of the contact part 111 has the same radius of curvature. Different parts of the contact part 111 can also have different radii of curvature. The smallest radius of curvature among all parts of the contact part 111 is greater than 20 mm. The contact part 111 has a sufficient radius of curvature to make the surface of the contact part 111 flat enough, so that the door body 20 can form a larger contact area with the contact part 111 when it is closed, thereby making the door seal 10 have a better sealing effect.

[0036] In some embodiments, the mounting portion 13, the sealing portion 11, and the connecting portion 12 are in a first reference direction (e.g., in the first reference direction). Figure 2 The two support portions 112 are arranged in a second reference direction (e.g., the Y direction as shown in 2) perpendicular to the first reference direction. The contact portions 111 connect the ends of the two support portions 112 away from the connecting portion 12 in the first reference direction at both ends in the second reference direction. Optionally, the door 20 can move closer to the device body 30 along the first reference direction to achieve door closure. In some embodiments, the mounting direction in which the mounting portion 13 enters the mounting groove 31 can also be the first reference direction.

[0037] In some embodiments, combined with Figure 3 In the arrangement direction of the support portion 112, multiple sealing ribs 1111 are spaced apart on the side of the contact portion 111 away from the mounting portion 13. The multiple sealing ribs 1111 protrude towards the door body 20 relative to the contact portion 111. When the door body 20 is closed, the multiple sealing ribs 1111 can form multiple seals with the door body 20, thereby improving the sealing effect. In related technologies, the door seal 10 is always extruded. Furthermore, since the door seal 10 needs to be arranged in a ring around the main body 30, the flatness and uniformity of the contact portion 111 may be unsatisfactory during manufacturing and use, potentially leading to poor contact between the contact portion 111 and the door body 20, or even partial failure to make contact. The sealing rib 1111 provided on the contact portion 111 allows the sealing rib 1111 to contact the door body 20 in a protruding manner relative to the contact portion 111. This can compensate 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 make sufficient contact with the door body 20 to achieve the desired sealing effect.

[0038] On the other hand, the material of the door body 20 can be glass or metal, etc. If the contact part 111 contacts the door body 20 in a completely flat and uniform manner, it may cause the contact part 111 to stick to the door body 20. By providing a protruding sealing rib 1111, the shape and pressure of the door seal 10 and the base of the door body 20 can be changed at the position of the sealing rib 1111. This allows for localized stress concentration near the sealing rib 1111 when the door body 20 is opened, thus improving the technical problem of adhesion between the door body 20 and the door seal 10.

[0039] Combination Figure 5The embodiment of the present application provides a door seal 10. The door seal 10 comprises a mounting portion 13, a sealing portion 11 and a connecting portion 12. The mounting portion 13 is used for mounting cooperation with equipment. The sealing portion 11 is used for abutting against a 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 surround to form a first cavity 110. An abutting piece 14 can be arranged in the first cavity 110.

[0040] The mounting portion 13 is used for mounting cooperation with equipment. The mounting portion 13 can be embedded, inserted or clamped in a mounting groove 31 of an equipment body 30. The mounting portion 13 mounted in the mounting groove 31 can be mounted through interference fit or connecting piece mounting and the like. There can be a certain pressure between the mounting portion 13 and the equipment body 30, so as to ensure good sealing performance. The mounting portion 13 can seal the gap between the door seal 10 and one side of the equipment body 30, thereby reducing the leakage of microwaves, steam or hot air and the like from between the door seal 10 and the equipment body 30.

[0041] The sealing portion 11 is used for abutting against the door body 20. In the case that the door body 20 is closed, the door body 20 and the equipment body 30 will exert pressure on the door seal 10, and the door body 20 can abut against the sealing portion 11. The sealing portion 11 can abut against the door body 20 more closely under the action of the pressure, so as to ensure that the sealing portion 11 has good sealing with 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 or hot air and the like from between the door seal 10 and the door body 20.

[0042] The connecting portion 12 can connect the mounting portion 13 and the sealing portion 11. In the description of the present application, in order to facilitate the description, the transition part between the mounting portion 13 and the sealing portion 11 is defined as the connecting portion 12. However, in other embodiments, the sealing portion 11 can be directly connected with the mounting portion 13. In other words, the connecting portion 12 of the present application can be composed of the part where the sealing portion 11 and the mounting portion 13 are close to each other and connected in other embodiments.

[0043] The sealing portion 11 and the connecting portion 12 surround to form the first cavity 110. The first cavity 110 surrounded by the sealing portion 11 and the connecting portion 12 can facilitate the deformation of the sealing portion 11 under the pressure of the door body 20, thereby increasing the contact area of the sealing portion 11 and the door body 20.

[0044] After the sealing portion 11 can contact the connecting portion 12 under the pressure of the door body 20, adhesion can be generated. In order to improve this situation, the abutting piece 14 is arranged in the first cavity 110, and the abutting piece 14 is clamped between the sealing portion 11 and the connecting portion 12.

[0045] Specifically, the abutting piece 14 can be arranged in the first cavity 110. The abutting piece 14 can reduce the direct contact between the sealing part 11 and the connecting part 12 on one hand, and can destroy the uniform distribution of pressure in the first cavity 110, so that the stress between the connecting part 12 and the abutting piece 14 can generate local stress concentration at the abutting piece 14 in the process of elastic recovery, and the rebound of the sealing part 11 can be reduced. In this way, the adhesion between the sealing part 11 and the connecting part 12, or between the sealing part 11 and the abutting piece 14 and the connecting part 12 respectively, can be reduced. The abutting piece 14 can also provide a certain support force for the sealing part 11, so that the sealing part 11 and the door body 20 can maintain sufficient pressure and ensure sufficient sealing effect.

[0046] In some embodiments, the sealing part 11 and the connecting part 12 adopt the same or similar organic materials such as rubber or plastic, which can cause the contact part 111 and the connecting part 12 to be slightly integrated under pressure, and then easily cause adhesion. In order to improve this situation, the material of the abutting piece 14 can be a material different from the sealing part 11 and the connecting part 12, such as a metal material, a ceramic material or other inorganic materials.

[0047] In some embodiments, the sealing part 11 includes the contact part 111 and the support part 112, and the two sides of the contact part 111 are connected to the connecting part 12 through the support part 112 respectively. The contact part 111 is used to abut against the door body 20 to form a seal when the door body 20 is closed. The support part 112 is used to connect the contact part 111 and the connecting part 12. The contact part 111, the support part 112 and the connecting part 12 surround to form the first cavity 110, and the abutting piece 14 is arranged in the first cavity 110 and clamped between the contact part 111 and the connecting part 12. Specifically, the abutting piece 14 can reduce the adhesion between the contact part 111 and the connecting part 12 in the above-mentioned manner.

[0048] In the first cavity 110, the abutting piece 14 can exist in different forms, and different embodiments of the abutting piece 14 will be introduced below. It can be understood that the embodiments can be combined with each other, and the schemes obtained by combining the following embodiments are also within the protection scope of the present application without mutual exclusion.

[0049] In combination with Figure 5 In some embodiments, the abutting piece 14 is an abutting protrusion. The abutting protrusion can be connected to the contact part 111 or the connecting part 12 by means of connection or adhesion. The abutting protrusion can also be integrally formed with the contact part 111 or the connecting part 12.

[0050] In some embodiments, the contact portion 111 is provided with at least one abutting protrusion on the side facing the mounting portion 13. When the contact portion 111 moves towards the connecting portion 12, the abutting protrusion can abut against the connecting portion 12, thereby reducing the problem of adhesion between the contact portion 111 and the connecting portion 12.

[0051] Further, in some embodiments, the contact portion 111 is provided with at least two abutting protrusions on the side facing the mounting portion 13, and the abutting protrusions are arranged in the arrangement direction of the support portion 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.

[0052] In some embodiments, the connecting portion 12 is provided with at least one abutting protrusion on the side facing the contact portion 111. When the contact portion 111 moves towards the connecting portion 12, the abutting protrusion can abut against the contact portion 111, thereby reducing the problem of adhesion between the contact portion 111 and the connecting portion 12.

[0053] In some embodiments, the connecting portion 12 is provided with at least two abutting protrusions on the side facing the contact portion 111, and the abutting protrusions are arranged in the arrangement direction of the support portion 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.

[0054] In some embodiments, the abutting protrusions are provided in at least two, and the at least two abutting protrusions are respectively integrally formed with the contact portion 111 and the connecting portion 12. That is, the contact portion 111 is provided with an abutting protrusion on the side facing the connecting portion 12, and the connecting portion 12 is provided with an abutting protrusion on the side facing the contact portion 111. The two abutting protrusions are arranged by being sandwiched between the contact portion 111 and the connecting portion 12, thereby changing the contact area and pressure distribution of the contact portion 111 and the connecting portion 12 under pressure, and thereby achieving the technical effect of preventing adhesion as described above.

[0055] Further, the at least two abutting protrusions are correspondingly arranged. Specifically, the projection of the abutting protrusion arranged on the connecting portion 12 in the first reference direction coincides with the projection of the abutting protrusion arranged on the contact portion 111 in the first reference direction. In other words, during the deformation of the abutting portion to approach the connecting portion 12, the two abutting protrusions abut against each other. In this way, when the contact portion 111 approaches the connecting portion 12, the contact portion 111 and the connecting portion 12 can have a larger spacing through the abutment of the two abutting protrusions, thereby further achieving the technical effect of preventing adhesion.

[0056] In some embodiments, the abutting member 14 is a separate part from the sealing portion 11 and the connecting portion 12. The abutting member 14 can extend into the first cavity 110, thereby achieving the aforementioned technical effect of preventing adhesion.

[0057] In combination Figure 6 and Figure 7 In some embodiments, at least one support rib 15 is arranged between the contact portion 111 and the connecting portion 12, and the support rib 15 connects the sealing portion 11 and the connecting portion 12. The extension direction of the support rib 15 is consistent with the arrangement direction of the sealing portion 11 and the mounting portion 13. On one hand, the support rib 15 can separate the connecting portion 12 and the contact portion 111, thereby preventing adhesion between the contact portion 111 and the connecting portion 12. On the other hand, the support rib 15 can support the contact portion 111 in case that the contact portion 111 tends to move close 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, so as to further optimize the sealing effect.

[0058] 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 enabling the contact portion 111 to generate pressure with the door body 20, so as to achieve the 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, thereby enabling the contact portion 111 to have greater positive pressure after abutting against the door body 20, so as to further improve the sealing effect.

[0059] In some embodiments, the door seal 10 is arranged in a ring shape. The door seal 10 is arranged around the opening of the equipment body 30, thereby preventing microwave, steam or hot air from leaking in the circumferential direction when the door body 20 is closed, so as to achieve good sealing effect.

[0060] In some embodiments, in combination Figure 4 The sealing portion 11 is provided with an exhaust hole 113 that is in communication with the inside of the sealing portion 11. The exhaust hole 113 is in communication with the first cavity 110. The exhaust hole 113 can exhaust the gas in the first cavity 110 in case that the sealing portion 11 is compressed or heated to expand, thereby reducing the generation of poor sealing. Optionally, the interval between the exhaust holes 113 is greater than or equal to one fourth of the total circumference of the door seal 10, thereby enabling the exhaust holes 113 to have a small exhaust rate while meeting the exhaust function. In this way, the door seal 10 can achieve sufficient buffering effect when the door body 20 is closed.

[0061] In some embodiments, in combination Figures 2 to 7In any of the drawings, the mounting portion 13 is hollowly arranged, and a second cavity 130 is formed. The second cavity 130 can increase the variability and compressibility of the mounting portion 13, and facilitate the assembly of the mounting portion 13 in the mounting groove 31. The mounting portion 13 is provided with tooth portions 131 on opposite sides thereof, which are arranged to extend obliquely from the mounting portion 13 towards the sealing portion 11. In the first reference direction, the tooth portions 131 are arranged in multiple. The tooth portions 131 can form multiple seals between the mounting portion 13 and the mounting groove 31, and increase the contact area with the mounting groove 31, thereby improving the sealing performance between the mounting portion 13 and the mounting groove 31. The tooth portions 131 are easy to deform, and the multiple tooth portions 131 are arranged to protrude relative to each other, which can provide an interference in an easy-to-deform manner, thereby improving the mounting stability of the mounting portion 13. The end of the mounting portion 13 can be further provided with a clearance groove, thereby providing clearance for the connecting member such as a screw or a rivet of the device body 30. The mounting portion 13 can also be provided with a communication hole that is in communication with the second cavity 130, thereby allowing the door seal 10 to reduce the total amount of expansion when it is expanded by heat by discharging gas from the second cavity 130, so as to ensure the stability of the sealing.

[0062] In some embodiments, the connecting portion 12 is further provided with a first water retaining portion 121 and a second water retaining portion 122 on opposite sides thereof. The first water retaining portion 121 extends from the connecting portion 12 along the direction of the sealing portion 11 towards the mounting portion 13, and is arranged to be spaced apart from the mounting portion 13. The second water retaining portion 122 extends from the connecting portion 12 along the spacing direction of the two support portions 112. Further, 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, and the second water retaining portion 122 is located on the side of the connecting portion 12 close to the opening of the device body 30. Optionally, the first water retaining portion 121 extends into the cooking cavity of the device body 30 from the opening.

[0063] The arrangement of the first water retaining portion 121 can allow the condensed water to flow back to the inside of the cooking cavity through the first water retaining portion 121, thereby avoiding the condensed water and hot steam from flowing into the mounting groove 31 to cause corrosion of the mounting groove 31. The second water retaining portion 122 can shield the side of the mounting groove 31 away from the opening, thereby further preventing the condensed water or external splashing water from entering the mounting groove 31, and reducing the possibility of corrosion of the mounting groove 31.

[0064] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
