When the design parameters or characteristics of the sealing structure fail to match the oven and door, heat and steam will leak through the sealing structure and / or require additional hinge opening force. Utility Model Content

[0003] Based on this, it is necessary to provide a steam oven.

[0004] The present application provides a steam oven, comprising: a door body; a box body, wherein a limiting cavity is provided at one end of the box body toward the door body; and a deformable sealing structure, wherein the sealing structure comprises a limiting portion and a sealing portion connected to the limiting portion, wherein the limiting portion is installed in the limiting cavity, and the sealing portion is inclined from the limiting portion toward a side away from the box body, and an inclination angle α is formed between the sealing portion and a radial cross-section of the box body, and satisfies 37°≤α≤42°.

[0005] With such arrangement, when the inclination angle α between the sealing portion and the radial cross-section of the box body is 37°≤α≤42°, the door body can smoothly enter the preset position through the sealing portion during the closing process of the door body and the box body, reducing the difficulty of user use and improving operation friendliness. The sealing portion can prevent the sealing structure from folding and deforming when the box body and the door body are closed, ensuring the airtightness of the steam oven during cooking, heating the ingredients evenly during cooking, and avoiding the loss of heat or steam during cooking; in the process of opening the door body and the box body, the sealing portion can ensure that the door body moves according to the preset track, reducing the shaking and friction generated when the door body and the box body are separated.

[0006] In one embodiment, the sealing portion includes a sealing segment and a guide segment connected to the sealing segment, and the sealing segment connects the guide segment to the limiting portion.

[0007] With this arrangement, the layout of the guide section connected to the sealing section can guide the door body when the door body and the box body are closed, so that the door body can follow the guide section to enter the preset position, thereby improving the sealing effect provided by the sealing section after the door body and the box body are closed.

[0008] In one embodiment, the outer side surface of the guide section is smooth.

[0009] With this arrangement, when the surface of the guide section contacting the door body is smooth, the guide section can help the door body fit smoothly with the box body after contacting the door body; the smooth outer surface can reduce the friction between the door body and the guide section, providing users with a smooth user experience.

[0010] In one embodiment, the outer side surface of the sealing portion is smooth.

[0011] With this arrangement, when the outer side surface of the sealing portion is smooth, the sealing of the chamber when the box body and the door body are closed can be improved, heat or steam leakage can be avoided, energy consumption of the steam oven when cooking food can be reduced, and the user's usage cost can be reduced.

[0012] In one embodiment, the sealing portion further includes a waistline segment, and the waistline segment is located between the sealing segment and the limiting portion.

[0013] With this arrangement, the waistline segment can avoid unnecessary increase in the hinge opening force when the user moves the door body, reduce the difficulty of use, facilitate user operation, avoid folding and deformation of the sealing part, improve the stability of the sealing part, and extend the service life of the sealing part.

[0014] In one embodiment, the sealing portion further includes a connecting section, which connects the waistline section and the limiting portion, and the outer side surface of the connecting section is a frosted surface.

[0015] With this arrangement, when the outer side surface of the connecting section is frosted, the anti-slip performance of the sealing structure is improved when the user uses it, so that it can provide the user with a good grip even when it is wet or greasy; secondly, the frosted surface helps to reduce the residue of fingerprints and stains, making it easier for users to clean and maintain, and reducing user maintenance and management costs.

[0016] In one embodiment, the limiting portion is detachably connected to the limiting cavity.

[0017] With such a configuration, the detachable connection mode facilitates the removal of the limiting part from the limiting cavity, making it easy for the user to disassemble and clean it or replace it after deformation, thereby reducing the user's maintenance cost.

[0018] In one embodiment, the limiting portion and the limiting cavity are interference fit.

[0019] Such an arrangement avoids the presence of gaps when the limiting part is installed in the limiting cavity, improves the sealing performance of the sealing structure, avoids the limiting part being in a stretched state in the limiting cavity to accelerate aging of the sealing structure, and reduces the user's management costs.

[0020] In one embodiment, the thickness of the guide section and / or the sealing section is greater than or equal to 1 mm.

[0021] Such an arrangement extends the service life of the guide section and / or the sealing section, avoids plastic deformation of the guide section and / or the sealing section in a high-temperature working environment, and provides a stable guiding function for the relative movement between the door body and the box body.

[0022] In one embodiment, the wall of the limiting cavity and the limiting portion are both square with rounded corners, the radius of the corner of the limiting portion is R1, and the radius of the corner of the limiting cavity is R2, satisfying: R1-R2≥5mm.

[0023] Such an arrangement provides sufficient compression for the limiting portion, preventing the four corners of the sealing structure from sinking and shifting inwards after being heated or aged, thereby ensuring the sealing performance of the sealing structure and improving the reliability of the sealing structure.

[0040] A steam oven is a household appliance that can place food inside the oven for baking and / or steaming. When using a steam oven for cooking, the sealing structure is continuously exposed to a high-temperature environment. When the design parameters or characteristics of the sealing structure fail to match the oven and door, heat and steam will leak through the sealing structure and / or require additional hinge opening force.

[0041] In order to solve the above problems, Figures 1 to 8 As shown, the present invention provides a steam oven 100 to improve cooking efficiency.

[0042] like Figure 1 ,to Figure 3 As shown, specifically, the present application provides a deformable sealing structure 30 for use in a steam oven 100, so that a user can smoothly open and close the steam oven 100 and improve the sealing performance of the steam oven. A steam oven 100 includes a door body 10, a box body 20, and a deformable sealing structure 30 provided on the box body 20. The box body 20 is provided with a limiting cavity 21 at one end facing the door body 10. The sealing structure 30 includes a limiting portion 31 and a sealing portion 32 connected to the limiting portion 31. The limiting portion 31 is installed in the limiting cavity 21. The sealing portion 32 is inclined from the limiting portion 31 toward the side away from the box body 20. There is an inclined angle α between the sealing portion 32 and the radial cross section of the box body 20, and the angle satisfies 37°≤α≤42°.

[0043] In the above-mentioned steam oven 100, when the inclination angle α between the sealing portion 32 and the radial cross-section of the box body 20 is 37°≤α≤42°, the sealing performance of the steam oven 100 can be improved. During the closing process of the door body 10 and the box body 20, the door body 10 can smoothly enter the preset position through the sealing portion 32, reducing the difficulty of user use and improving the operation friendliness. The sealing portion 32 can prevent the sealing structure 30 from folding and deforming when the box body 20 and the door body 10 are closed, ensuring the airtightness of the steam oven 100 during cooking, making the ingredients heated evenly during cooking, and avoiding the loss of heat or steam during cooking; during the opening process of the door body 10 and the box body 20, the sealing portion 32 can ensure that the door body 10 moves according to the preset track, reducing the shaking and friction generated when the door body 10 is separated from the box body 20.

[0044] It should be noted that, in the above description, the preset position refers to the relatively complete fit between the door body 10 and the box body 20, so that a closed chamber is formed between the door body 10 and the box body 20.

[0045] See also Figure 6 In one embodiment, the sealing portion 32 includes a sealing segment 321 and a guide segment 322 connected to the sealing segment 321. The sealing segment 321 connects the guide segment 322 to the limiting portion 31. The layout of the sealing segment 321 connected to the guide segment 322 facilitates guiding the door body 10 when the door body 10 and the box body 20 are closed, allowing the door body 10 to follow the guide segment 322 to enter the preset position, thereby improving the sealing effect provided by the sealing segment 321 after the door body 10 and the box body 20 are closed.

[0046] See also Figure 6 In one embodiment, the outer side of the guide section 322 is smooth. This smooth outer side of the guide section 322 allows the guide section 322 to contact the door body 10 and help the door body 10 fit smoothly against the box body 20. The smooth outer side reduces friction between the door body 10 and the guide section 322, providing a smooth user experience.

[0047] Similarly, see Figure 6 The outer surface of the sealing portion 32 can also be smooth, which is beneficial to improving the sealing of the chamber when the box body 20 and the door body 10 are closed, avoiding heat or steam leakage, and reducing energy consumption of the steam oven 100 when cooking food.

[0048] It should be noted that in the above description, the outer side refers to the side closer to the door 10 relative to the cabinet 20 and the door 10, with the outer side being closer to the cooking chamber in the cabinet 20 and the inner side being closer to the door 10. In this embodiment, the outer sides of the guide section 322 and the sealing portion 32 are smooth, which is achieved by using a mold.

[0049] See also Figure 6In one embodiment, the sealing portion 32 further includes a waistline segment 323, which is located between the sealing segment 321 and the limiting portion 31. Providing the waistline segment 323 on the sealing portion 32 can improve the stability of the sealing portion 32, avoid unnecessary increase in the hinge opening force when the user moves the door body 10, reduce user difficulty, facilitate user operation, prevent the sealing portion 32 from folding and deformation, and extend the service life of the sealing portion 32.

[0050] In this embodiment, the compression amount of the sealing structure 30 controlled by the waistline segment 323 can be determined according to factors such as the maximum sealing medium pressure and temperature when the steam oven 100 is in use.

[0051] See also Figure 6 In one embodiment, the sealing portion 32 further includes a connecting section 324 that connects the waistline section 323 to the stopper 31. The outer surface of the connecting section 324 has a frosted surface. The frosted outer surface of the connecting section 324 improves the anti-slip performance of the sealing structure 30, providing a good grip even when wet or greasy. Furthermore, the frosted surface helps reduce fingerprints and stains, making it easier for users to clean and maintain, thereby reducing maintenance costs.

[0052] Optionally, in the present embodiment, the outer side surface of the connecting section 324 is a frosted surface made by using a mold having a frosted surface. In other embodiments of the present application, the frosted surface of the outer side surface of the connecting section 324 can also be implemented by grinding a friction product, or by coating the surface with a friction coating to achieve the frosted outer side surface of the connecting section 324, as long as it can facilitate the installation of the sealing structure 30.

[0053] See also Figure 6 In one embodiment, the limiting portion 31 is detachably connected to the limiting cavity 21. The detachable connection between the limiting portion 31 and the limiting cavity 21 facilitates the removal of the limiting portion 31 from the limiting cavity 21, making it easier for the user to disassemble and clean the sealing structure 30 or replace it after deformation, thereby reducing the user's maintenance costs.

[0054] Optionally, in the present embodiment, the limiting portion 31 and the limiting cavity 21 are implemented as a detachable connection. In other embodiments of the present application, the connection between the limiting portion 31 and the limiting cavity 21 can also be implemented as a pre-buried non-detachable connection such as gluing, etc., as long as it is convenient to install the sealing structure 30 on the box body 20 and meets the actual usage requirements of the customer.

[0055] See also Figures 1 to 8In a specific implementation, the sealing structure 30 is integrally formed and made of a flexible and / or elastic material. This reduces the production cost of the sealing structure 30, improves its reliability, and extends its service life. This facilitates installation and / or disassembly by customers and installers, making it easier for customers to disassemble, clean, and maintain the seal during subsequent use. Customers can also replace the sealing structure 30 if it ages or becomes damaged, reducing subsequent maintenance costs. This also prevents the sealing structure 30 from scratching the user during use, improving the safety and sealing performance of the sealing structure 30.

[0056] Optionally, in the present embodiment, the sealing structure 30 is implemented as an integral molding. In other embodiments of the present application, the sealing structure 30 may also be implemented as a split molding, as long as the stability and reliability of the sealing structure 30 can be improved.

[0057] It should be noted that, in this embodiment, the sealing structure 30 is implemented as a material with flexibility and / or elasticity, such as silicone.

[0058] See also Figure 6 In one embodiment, the limiting portion 31 has an interference fit with the limiting cavity 21. The interference fit between the limiting portion 31 and the limiting cavity 21 helps improve the sealing performance of the sealing structure 30, avoids gaps when the limiting portion 31 is installed in the limiting cavity 21, and prevents the limiting portion 31 from being in a stretched state within the limiting cavity 21, which accelerates aging of the sealing structure 30. Optionally, in other embodiments, the limiting portion 31 and the limiting cavity 21 can also be fixedly connected by gluing.

[0059] like Figures 5 and 6 As shown, in one embodiment, the thickness of the guide segment 322 and / or the sealing segment 321 is greater than or equal to 1 mm. Limiting the thickness of the guide segment 322 and / or the sealing segment 321 helps extend the service life of the guide segment 322 and / or the sealing segment 321, prevents the guide segment 322 and / or the sealing segment 321 from deformation in a high-temperature operating environment, provides a stable sealing effect for the relative movement between the door body 10 and the box body 20, and improves the service life of the seal.

[0060] It should be noted that when the door body 10 and the box body 20 are closed, since the sealing part 32 first contacts the surface of the door body 10, when the thickness of the sealing part 32 is less than 1 mm, the sealing part 32 is likely to flip down with the door body 10, resulting in a weakening of the sealing between the door body 10 and the box body 20.

[0061] See also Figures 7 and 8In one embodiment, the walls of the limiting cavity 21 and the limiting portion 31 are both square with rounded corners. The corner radius of the limiting portion 31 is R1, and the corner radius of the limiting cavity 21 is R2, satisfying the following: R1-R2 ≥ 5mm. A difference of 5mm between the corner radius R1 of the limiting portion 31 and the corner radius R2 of the limiting cavity 21 improves the reliability of the sealing structure 30 by providing sufficient compression for the limiting portion 31, preventing the corners of the sealing structure 30 from sinking and shifting inward due to heat or aging, thereby ensuring the sealing performance of the sealing structure 30. It should be noted that, when R1-R2≥5mm; the thickness of the sealing part 32≥1mm is satisfied, it can be ensured that the compression amount of the sealing part 32 is within an appropriate range, and the thickness of the sealing part 32 is avoided to be too thick, resulting in a reduction in the compression amount of the sealing part 32; when the medium pressure between the door body 10 and the box body 20 increases or as the hinge force decays, the sealing structure 30 will have reliability problems, resulting in air leakage in the steam oven 100; simply increasing the hinge force will affect the user's experience of opening the door; therefore, satisfying R1-R2≥5mm; the thickness of the sealing part 32≥1mm can obtain a steam oven 100 with excellent sealing stability.

[0062] In this embodiment, the wall corners of the limiting portion 31 and the limiting cavity 21 are implemented as rounded corners. In other embodiments of the present application, the rounded corners can also be implemented as right angles, as long as the stress concentration phenomenon when the limiting portion 31 is pressed into the limiting cavity 21 can be avoided, thereby reducing the subsequent maintenance and management costs.

[0063] Optionally, in the present embodiment, the limiting portion and the wall radius of the limiting cavity 21 are implemented as four relatively arranged ones. In other embodiments of the present application, the limiting portion 31 may also be implemented as at least three relatively arranged ones, as long as the contact pressure of the sealing structure 30 on the door body 10 during use can be balanced.

[0064] Optionally, in this embodiment, the chamber of the limiting cavity 21 is implemented as a rounded rectangular parallelepiped. In other embodiments of the present application, the chamber of the limiting cavity 21 can also be implemented as a rounded cube, rounded triangle or other polygonal body, as long as it is convenient for the detachable connection of the sealing structure 30.

[0065] Optionally, in this embodiment, the inner wall of the limiting cavity 21 is implemented as a frosted surface. In other embodiments of the present application, the inner wall of the limiting cavity 21 can also be implemented as a sanded surface, as long as the limiting part can be prevented from being displaced or slipping in the limiting cavity 21.

[0066] See also Figure 6In one embodiment, a stop groove is defined in the limiting cavity 21, and the limiting portion 31 includes a limit strip. When the limiting portion 31 is pressed into the limiting cavity 21, the limit strip on the limiting portion 31 fills the stop groove, thereby preventing the limiting portion 31 from shifting along the axis and improving the stability of the sealing structure 30. It should be noted that in this embodiment, the number of both the stop grooves and the limit strips is eight. In other embodiments of the present application, the number of the stop grooves may be greater than or less than eight, as long as the displacement of the limiting portion 31 along the axis is prevented and the stability of the sealing structure 30 is improved.

[0067] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
