In the description of the above embodiments, specific features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0050] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0051] Reference Figures 1-6 This is one embodiment of the cooking equipment of this utility model. The cooking equipment can be an oven, a steam oven, a microwave oven, or a microwave-steam-oven combination machine.

[0052] The cooking equipment includes a cabinet 100, an inner pot 200, and a door 300.

[0053] The inner liner 200 is located inside the box body 100 and forms a cooking cavity for accommodating food to be cooked. The front side of the inner liner 200 has an inner liner door frame 210 with a first opening.

[0054] The door 300 is pivotally mounted at the first opening of the inner door frame 210 to close the cooking cavity.

[0055] like Figure 3 and Figure 6 As shown, the outer sealing ring 500 is disposed between the mating surfaces of the door body 300 and the inner door frame 210, and is used to achieve a seal between the two when the door body 300 is closed.

[0056] The inner sealing ring 400 is located inside the outer sealing ring 500 and is located on the side of the door 300 facing the inner liner 200. The bottom edge of the inner sealing ring 400 forms a downwardly inclined guide lip 420 that extends towards the inner liner 200. The inclined extension direction of the guide lip 420 forms a condensate guiding path from the door 300 to the inner liner 200.

[0057] When condensation occurs on the inside of the door glass 330 or other door body 300 components during cooking, water droplets flow downwards along the inner surface of the door body 300 and eventually collect on the guide lip 420 of the inner sealing ring 400. Because the guide lip 420 extends downwards and towards the inner liner 200, the condensation can be smoothly guided back to the bottom of the inner liner 200 along this inclined surface, preventing water droplets from accumulating and dripping at the bottom of the door body 300 or in other gaps.

[0058] The aforementioned cooking equipment achieves double sealing protection for the cooking cavity by assembling an outer sealing ring 500 and an inner sealing ring 400 on the door 300. This more effectively prevents the leakage of hot air and water vapor from the cavity, reducing air leakage and abnormal noise. In addition, the bottom of the inner sealing ring 400 is provided with a guide lip 420, which can guide water droplets condensed on the door 300 back to the bottom of the inner liner 200 through its downward tilting structure that extends towards the inner liner 200. This significantly reduces or avoids the accumulation and dripping of condensate on the glass of the door 300 or other parts, improving the reliability of the cooking equipment and the convenience of user operation.

[0059] In some embodiments of this application, such as Figure 4 As shown, the door 300 includes an outer decorative frame 310, an inner metal door frame 320, an inner glass panel 330, and a front panel 340.

[0060] The outer decorative frame 310 forms the outer outline of the door 300. The inner metal door frame 320 is fixedly connected to the outer decorative frame 310 by fasteners or other means, forming the structural skeleton of the door 300. A choke is installed inside the inner metal door frame 320 to absorb and attenuate any leaked microwave energy, ensuring the safety of the equipment.

[0061] The inner glass 330 is installed on the side of the inner metal door frame 320 facing the inner pot 200, making it convenient for users to observe the cooking process.

[0062] The front panel 340 is fixed to the front side of the outer decorative frame 310, forming the front appearance of the door 300.

[0063] In some embodiments of this application, the outer decorative frame 310 has a second opening 311. The second opening 311 is a window on the front of the door 300 for installing and securing internal components.

[0064] The inner metal door frame 320 has an annular boss 321 protruding towards the inner liner 200, and the annular boss 321 is located within the second opening 311. The annular boss 321 has a ring-shaped structure and protrudes from the side of the inner metal door frame 320 facing the inner liner 200, for installing the inner glass 330 and forming a sealing structure.

[0065] The inner glass 330 is located inside the inner ring wall of the annular boss 321, and there is a gap between the inner glass 330 and the inner ring wall of the annular boss 321. This gap is used to install the inner sealing ring 400. The inner sealing ring 400 is fixed between the inner glass 330 and the annular boss 321.

[0066] There is a gap between the second opening 311 of the outer decorative frame 310 and the outer ring wall of the annular boss 321, and the outer sealing ring 500 is fixed between the outer decorative frame 310 and the annular boss 321. The annular boss 321 not only provides a mounting base for the inner glass 330, but also provides reliable structural support for the fixing of the inner and outer sealing rings.

[0067] In another embodiment, one or more layers of door glass may be provided between the inner metal door frame 320 and the front door panel 340.

[0068] See Figure 3 The inner sealing ring 400 includes a first mounting portion 410 and a first sealing portion.

[0069] The first mounting portion 410 is used to fix to the outer periphery of the inner glass 330 of the door, for example, by interference fit, bonding or other fixing methods to achieve a stable connection. The bottom edge of the first mounting portion 410 is formed with the guide lip 420, which is inclined downward and extends toward the inner liner 200 to collect and guide the condensate generated inside the door 300 back to the inner liner 200.

[0070] The first sealing part extends along the top and sides of the first mounting part 410 toward the inner liner 200, and is used to tightly abut against the corresponding part of the inner liner door frame 210 when the door 300 is closed, forming an inner seal to prevent the heat and moisture in the cooking cavity from leaking out.

[0071] Furthermore, such as Figure 6 As shown, in order to further improve the sealing performance between the inner sealing ring 400 and the annular boss 321 of the metal door frame 320 inside the door body 300, the outer surface of the first mounting part 410 may have at least one first rib 411. During assembly, the first rib 411 can be squeezed to generate deformation and tightly abut against the inner ring wall of the annular boss 321, thereby achieving the sealing of the glass 330 inside the door.

[0072] In some embodiments of this application, the outer sealing ring 500 includes a second mounting portion 510 and a second sealing portion 520.

[0073] The second mounting part 510 is used to securely fix the outer sealing ring 500 to the outer decorative frame 310. The specific fixing method can be selected according to the actual design, such as snap-fit ​​connection, adhesive bonding, screw fixing, etc.

[0074] The second sealing part 520 extends from the second mounting part 510 in the direction toward the inner pot 200. Its main function is to form an effective contact with the corresponding part of the inner pot door frame 210 when the door 300 is closed, forming an outer sealing barrier to further prevent the leakage of heat, water vapor and microwave energy in the cooking cavity and enhance the overall sealing reliability.

[0075] Furthermore, such as Figure 3 The second sealing part 520 includes a connecting part 521, a first abutting part 522, and a second abutting part 523.

[0076] The connecting part 521 extends from the second mounting part 510 toward the inner liner 200, serving as a bridge connecting the second mounting part 510 and the subsequent abutting part.

[0077] The first abutment portion 522 is connected to the connecting portion 521, and the two form a certain angle between them. This angle design helps the first abutment portion 522 to contact the inner door frame 210 at a suitable angle when the door 300 is closed, generating a pre-tightening force, thereby improving the sealing effect.

[0078] The second abutting part 523 is connected to the first abutting part 522, and its extension direction is approximately parallel to the inner glass 330 of the door.

[0079] As the door 300 is about to close, the parallel surface of the second abutment 523 can play a certain guiding role. As the door 300 closes, the second abutment 523 gradually contacts the inner door frame 210 to form a wider sealing contact surface, thereby improving the final sealing performance.

[0080] In some embodiments of this application, in order to securely fix the second mounting portion 510 within the second opening 311 of the outer decorative frame 310, a T-shaped protrusion 312 is integrally formed or fixedly connected along the circumferential direction of the inner wall of the second opening 311. Correspondingly, the second mounting portion 510 is provided with a T-shaped groove that matches the shape and size of the T-shaped protrusion 312. By engaging the T-shaped groove with the T-shaped protrusion 312, a quick, convenient, and reliable fixation between the outer sealing ring 500 and the outer decorative frame 310 can be achieved. This mating method effectively prevents the outer sealing ring 500 from shifting or falling off during use, ensuring that it is always in the correct working position.

[0081] In some embodiments of this application, the outer surface of the second mounting part 510 is provided with at least one second protruding rib 511. During assembly, the second protruding rib 511 can be squeezed to deform and closely abut against the outer ring wall of the annular boss 321, thereby achieving a seal between the inner metal door frame 320 and the outer decorative frame 310.

[0082] In some embodiments of this application, the thickness of the guide lip 420 gradually decreases towards the inner liner 200.

[0083] The thickness of the guide lip 420 is set to gradually decrease along its direction from the connection with the first mounting part 410 to its free end. The gradually thinning edge can reduce the adhesion of water droplets to its surface, making it easier for condensate to overcome surface tension and flow downward under the action of gravity, avoiding the formation of water droplets hanging or accumulating at the end of the lip, which can improve the guiding efficiency and prevent secondary dripping.

[0084] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
