[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0041] Combination Figures 1 to 3 According to an embodiment of the present invention, a cooking device 100 includes a body 10 and a door 20. The body 10 has a cooking cavity 11 with an opening 111 at the front. The body 10 is equipped with a microwave heating unit for heating items inside the cooking cavity 11. The door 20 is used to open and close the opening 111, allowing items to be heated to be placed into the cooking cavity 11 through the opening 111. When the door 20 closes the opening 111, the items are heated by the microwave heating unit. Exemplarily, the microwave heating unit may include a magnetron.

[0042] Combination Figure 4 and Figure 5The cooking device 10 has a first mating surface 12, and the door 20 has a second mating surface 21. The first mating surface 12 surrounds the opening 111. When the door 20 closes the opening 111, the first mating surface 12 and the second mating surface 21 are connected front to back to limit microwave penetration. Specifically, after the door 20 closes the opening 111, the microwave heating unit operates to heat the items inside the cooking cavity 11. Microwaves can penetrate the surface of the items and heat their interiors rapidly. By setting the first mating surface 12 and the second mating surface 21 to connect along the front to back of the cooking device 100, the gap between the door 20 and the cooking device 10 can be sealed, preventing microwaves from penetrating through the gap between the door 20 and the cooking device 100 to the outside of the cooking device 100 during operation, thus avoiding any impact on the user.

[0043] The cooking equipment 100 of this utility model embodiment can be a microwave oven, or a microwave oven with microwave function, a gas microwave oven, a gas microwave steam oven, etc.

[0044] According to the embodiment of the present utility model, the cooking device 100 has a first mating surface 12 on the body 10 and a second mating surface 21 on the door 20. The first mating surface 12 and the second mating surface 21 are mated together, which can prevent microwave leakage during the operation of the cooking device 100 and improve the safety of the cooking device 100.

[0045] The main body 10 has a first mating surface 12, and the door 20 has a second mating surface 21. The first mating surface 12 and the second mating surface 21 can be constructed with different structures. For example, one of the first mating surface 12 and the second mating surface 21 can be the surface of a metal protrusion; the other can be a plane flush with the back of the door 20 or the front surface of the main body 10, or the bottom surface of a groove, or the surface of a metal protrusion. The following describes different configurations of the first mating surface 12 and the second mating surface 21 in some embodiments of the present invention with reference to the accompanying drawings. The cooking device 100 of the present invention may include, but is not limited to, the following embodiments.

[0046] Implementation Method 1

[0047] Combination Figure 4 The front surface of the body 10 is provided with a first metal protrusion 13, and the top surface of the first metal protrusion 13 is constructed as a first mating surface 12. By providing the first metal protrusion 13 on the front surface of the body 10, the first metal protrusion 13 can improve the structural strength of the front surface of the body 10 on the one hand, and facilitate its fit with the second mating surface 21 on the other hand, sealing the gap between the door 20 and the body 10. When the microwaves in the cooking cavity 11 reach the position of the first metal protrusion 13, the microwaves cannot penetrate the metal parts, thus avoiding microwave leakage and improving the safety of the cooking equipment 100.

[0048] For example, the first metal protrusion 13 can be formed by stamping. The body 10 may include a front frame panel, which may be disposed on the front surface of the body 10. At least a portion of the front frame panel may protrude in a direction away from the cooking cavity 11 to form the first metal protrusion 13; or a rib may be welded to the front frame panel, and the rib forms the first metal protrusion 13. The first metal protrusion 13 can strengthen the structural strength of the front frame panel and facilitate the fit between the first mating surface 12 and the second mating surface 21, sealing the gap between the door 20 and the body 10.

[0049] The second mating surface 21 is provided on the door body 20 and mates with the first mating surface 12. The second mating surface 21 can be configured in different structures. For example, the second mating surface 21 can be a plane; or, the second mating surface 21 can be the bottom surface of the groove; or, the second mating surface 21 can be the top surface of a metal protrusion.

[0050] Combination Figure 5 In the first embodiment, the second mating surface 21 is a plane flush with the back surface of the door body 20. Specifically, the door body 20 has a back surface and a front surface. The back surface of the door body 20 faces the cooking cavity 11 when the opening 111 is closed, and the front surface of the door body 20 faces away from the cooking cavity 11, that is, the side of the door body 20 facing the user when the opening 111 is closed. The fact that the second mating surface 21 is a plane flush with the back surface of the door body 20 facilitates the processing and shaping of the door body 20. Furthermore, by setting the first metal protrusion 13 to mate with the plane, it facilitates the fit between the first mating surface 12 and the second mating surface 21, avoiding unevenness on the front surface of the machine body 10 or the back surface of the door body 20, which could cause gaps between the door body 20 and the machine body 10. This improves the sealing effect between the door body 20 and the machine body 10, prevents microwave leakage, and thus enhances the safety of the cooking equipment 100.

[0051] In the second embodiment, a first groove is provided on the back of the door 20, and the bottom surface of the first groove is constructed as a second mating surface 21. For example, after the door 20 closes the opening 111, the first metal protrusion 13 can extend into the first groove, and the first mating surface 12 and the second mating surface 21 cooperate to prevent microwaves from passing through between the door 20 and the body 10, thereby preventing microwave leakage and improving the safety of the cooking equipment 100.

[0052] For example, the first groove can be formed by stamping. The door body 20 may include a metal back plate 22, which may be disposed on the back of the door body 20. At least a portion of the metal back plate 22 may be recessed toward the front of the door body 20 to form the first groove. The first groove can enhance the structural strength of the metal back plate 22 and facilitate the fit between the first mating surface 12 and the second mating surface 21, thus preventing microwave leakage.

[0053] In the third embodiment, a second metal protrusion is provided on the back of the door 20, and the top surface of the second metal protrusion is constructed as a second mating surface 21. By providing a second metal protrusion on the back of the door 20, the second metal protrusion can improve the structural strength of the back of the door 20 on the one hand, and facilitate its fit with the first mating surface 12 on the other hand, sealing the gap between the door 20 and the body 10. When the microwaves in the cooking cavity 11 reach the positions of the first metal protrusion 13 and the second metal protrusion, the microwaves cannot penetrate the metal parts, thus preventing microwave leakage and improving the safety of the cooking equipment 100.

[0054] For example, the second metal protrusion can be formed by stamping. The door body 20 may include a metal back plate 22, which may be disposed on the back of the door body 20. At least a portion of the metal back plate 22 may protrude toward the cooking cavity 11 to form the second metal protrusion; or the second metal protrusion may be formed by welding ribs to the metal back plate 22. The ribs form the second metal protrusion. The second metal protrusion can strengthen the structural strength of the door body 20 and facilitate the fit between the first mating surface 12 and the second mating surface 21, sealing the gap between the door body 20 and the body 10.

[0055] In addition, a sealing structure can be provided between the aforementioned body 10 and door 20.

[0056] Combination Figures 4 to 7 In some embodiments, a first sealing ring 14 may be provided on the front surface of the body 10. The first sealing ring 14 is located inside the first metal protrusion 13. When the door 20 closes the opening 111, the first sealing ring 14 seals against the back of the door 20. When the door 20 closes the opening 111, the first sealing ring 14 can seal the gap between the door 20 and the body 10, preventing leakage of steam, hot air, etc., and improving the energy efficiency and safety of the cooking equipment 100.

[0057] For example, the cooking device 100 may have functions such as steaming, baking, and microwaving. By setting a first sealing ring 14 on the front surface of the body 10, the sealing performance of the cooking device 100 is improved, which makes it easier to ensure more precise control of temperature and humidity inside the cooking device 100 and ensure the cooking effect of the cooking device 100.

[0058] In addition, the first sealing ring 14 is located inside the first metal protrusion 13. The first sealing ring 14 can seal the steam, fumes and other substances generated in the cooking cavity 11, so as to avoid affecting the first metal protrusion 13.

[0059] Combination Figure 7Furthermore, the dimension of the first sealing ring 14 protruding from the front surface of the body 10 is H1, and the dimension of the first metal protrusion 13 protruding from the front surface of the body 10 is H2, where H2 < H1. That is, the dimension of the first metal protrusion 13 protruding from the front surface of the body 10 is smaller than the dimension of the first sealing ring 14 protruding from the front surface of the body 10. The smaller dimension of the first metal protrusion 13 protruding from the front surface of the body 10 facilitates the processing and shaping of the body 10 and makes cleaning of the cooking equipment 100 easier. The larger dimension of the first sealing ring 14 protruding from the front surface of the body 10 facilitates the cooperation between the first sealing ring 14 and the door 20, improving the sealing effect of the cooking equipment 100. It can also effectively isolate the oil fumes and steam generated by food during cooking, preventing the oil fumes and steam from affecting the first metal protrusion 13, ensuring the cooperation between the first mating surface 12 and the second mating surface 21, preventing microwave leakage, and improving the safety and service life of the cooking equipment 100.

[0060] The protruding size of the first sealing ring 14 refers to the protruding size of the first sealing ring 14 in its natural state, or the protruding size of the first sealing ring 14 when it is not compressed by the door body 20.

[0061] Optionally, the ratio of H1 / H2 is greater than or equal to 3 and less than or equal to 4. This facilitates the mating of the first sealing ring 14 with the door body 20, improving the sealing effect of the cooking equipment 100. Furthermore, the first sealing ring 14 effectively isolates oil fumes and steam generated during cooking, preventing these substances from affecting the first metal protrusion 13. This ensures proper mating of the first mating surface 12 and the second mating surface 21, preventing microwave leakage and enhancing the safety and lifespan of the cooking equipment 100.

[0062] In other embodiments, a second sealing ring may be provided on the back of the door 20. The second sealing ring is located inside the second mating surface 21. When the door 20 closes the opening 111, the second sealing ring is in a sealing fit with the front surface of the machine body 10. When the door 20 closes the opening 111, the second sealing ring can seal the gap between the door 20 and the machine body 10, preventing leakage of steam, hot air, etc., and improving the energy efficiency and safety of the cooking equipment 100.

[0063] For example, the cooking device 100 may have functions such as steaming, baking, and microwaving. By setting a second sealing ring on the back of the door 20, the sealing performance of the cooking device 100 is improved, which makes it easier to ensure more precise control of temperature and humidity inside the cooking device 100 and ensure the cooking effect of the cooking device 100.

[0064] Furthermore, the dimension of the second sealing ring protruding from the back of the door body 20 is H3, and the dimension of the first metal protrusion 13 protruding from the front surface of the body 10 is H2, where H2 < H3. That is, the dimension of the first metal protrusion 13 protruding from the front surface of the body 10 is smaller than the dimension of the second sealing ring protruding from the back of the door body 20. The smaller dimension of the first metal protrusion 13 protruding from the front surface of the body 10 facilitates the processing and shaping of the body 10 and makes cleaning of the cooking equipment 100 easier. The larger dimension of the second sealing ring protruding from the back of the door body 20 facilitates the fit between the second sealing ring and the body 10, improving the sealing effect of the cooking equipment 100. It also effectively isolates oil fumes and steam generated during cooking, preventing these fumes and steam from affecting the first metal protrusion 13, ensuring the fit between the first mating surface 12 and the second mating surface 21, preventing microwave leakage, and improving the safety of using the cooking equipment 100.

[0065] Optionally, the ratio of H3 / H2 is greater than or equal to 3 and less than or equal to 4. This facilitates the mating of the second sealing ring with the door 20, improving the sealing effect of the cooking equipment 100. The second sealing ring effectively isolates oil fumes and steam generated during cooking, preventing these substances from affecting the first metal protrusion 13. This ensures proper mating of the first mating surface 12 and the second mating surface 21, preventing microwave leakage and improving the safety and lifespan of the cooking equipment 100.

[0066] The protruding size of the second sealing ring refers to the protruding size of the second sealing ring in its natural state, or the protruding size of the second sealing ring when it is not compressed by the body 10.

[0067] Implementation Method 2

[0068] The back of the door 20 is provided with a third metal protrusion, and the top surface of the third metal protrusion is constructed as a second mating surface 21. By providing a third metal protrusion on the back of the door 20, the third metal protrusion can improve the structural strength of the back of the door 20 on the one hand, and facilitate its fit with the first mating surface 12 on the other hand, sealing the gap between the door 20 and the body 10. When the microwaves in the cooking cavity 11 reach the position of the third metal protrusion, the microwaves cannot penetrate the metal parts, thus preventing microwave leakage and improving the safety of the cooking equipment 100.

[0069] For example, the third metal protrusion can be formed by stamping. The door body 20 may include a metal back plate 22, which may be disposed on the back of the door body 20. At least a portion of the metal back plate 22 may protrude toward the cooking cavity 11 to form the third metal protrusion; or the third metal protrusion may be formed by welding ribs to the metal back plate 22. The ribs form the third metal protrusion. The third metal protrusion can strengthen the structural strength of the metal back plate 22 and facilitate the fit between the first mating surface 12 and the second mating surface 21, sealing the gap between the door body 20 and the machine body 10.

[0070] The first mating surface 12 is provided on the body 10 and mates with the second mating surface 21. The first mating surface 12 can be configured in different ways. For example, the first mating surface 12 can be a plane; or, the first mating surface 12 can be the bottom surface of the groove; or, the first mating surface 12 can be the top surface of a metal protrusion.

[0071] In the first embodiment, the first mating surface 12 is a plane flush with the front surface of the body 10. Specifically, the front surface of the body 10 is the side of the body facing the user when the door 20 is opened 111. The second mating surface 21 is a plane flush with the front surface of the body 10, which facilitates the processing and forming of the body 10. By setting a third metal protrusion to mate with the plane, it is easy to fit the first mating surface 12 and the second mating surface 21 together, avoiding unevenness on the front surface of the body 10 or the back surface of the door 20, which would cause gaps between the door 20 and the body 10. This improves the sealing effect between the door 20 and the body 10, prevents microwave leakage, and thus improves the safety of using the cooking equipment 100.

[0072] In the second embodiment, the front surface of the body 10 is provided with a second groove, and the bottom surface of the second groove is constructed as a first mating surface 12. For example, after the door 20 closes the opening 111, the third metal protrusion can extend into the second groove, and the first mating surface 12 and the second mating surface 21 cooperate to prevent microwaves from passing through between the door 20 and the body 10, thereby preventing microwave leakage and improving the safety of the cooking equipment 100.

[0073] In addition, a sealing structure can be provided between the aforementioned body 10 and door 20.

[0074] In some embodiments, a third sealing ring may be provided on the front surface of the body 10. The third sealing ring is located inside the first mating surface, and when the door 20 closes the opening 111, the third sealing ring is sealed to the back of the door 20. When the door 20 closes the opening 111, the third sealing ring can seal the gap between the door 20 and the body 10, preventing leakage of steam, hot air, etc., and improving the energy efficiency and safety of the cooking equipment 100.

[0075] For example, the cooking device 100 may have functions such as steaming, baking, and microwaving. By setting a third sealing ring on the front surface of the body 10, the sealing performance of the cooking device 100 is improved, which makes it easier to ensure more precise control of temperature and humidity inside the cooking device 100 and ensure the cooking effect of the cooking device 100.

[0076] In addition, the third sealing ring is located on the inner side of the first mating surface. The third sealing ring can seal the steam, fumes and other substances generated in the cooking cavity 11, so as to avoid affecting the third metal protrusion.

[0077] Furthermore, the dimension of the third sealing ring protruding from the front surface of the body 10 is H4, and the dimension of the third metal protrusion protruding from the front surface of the body 10 is H5, where H5 < H4. That is, the dimension of the third metal protrusion protruding from the back of the body 20 is smaller than the dimension of the third sealing ring protruding from the front surface of the body 10. The smaller dimension of the third metal protrusion protruding from the back of the body 20 facilitates the processing and shaping of the body 10 and makes cleaning of the cooking equipment 100 easier. The larger dimension of the third sealing ring protruding from the front surface of the body 10 facilitates the mating of the third sealing ring with the body 20, improving the sealing effect of the cooking equipment 100. It can also effectively isolate the oil fumes and steam generated during the cooking process, preventing the oil fumes and steam from affecting the third metal protrusion, ensuring the mating of the first mating surface 12 and the second mating surface 21, preventing microwave leakage, and improving the safety and service life of the cooking equipment 100.

[0078] Optionally, the ratio of H4 / H5 is greater than or equal to 3 and less than or equal to 4. This facilitates the mating of the third sealing ring with the door 20, improving the sealing effect of the cooking equipment 100. The third sealing ring effectively isolates oil fumes and steam generated during cooking, preventing these substances from affecting the third metal protrusion, ensuring proper mating of the first mating surface 12 and the second mating surface 21, preventing microwave leakage, and improving the safety and lifespan of the cooking equipment 100.

[0079] The protruding dimension of the third sealing ring refers to the protruding dimension of the third sealing ring in its natural state, or the protruding dimension of the third sealing ring when it is not compressed by the door body 20.

[0080] In other embodiments, a fourth sealing ring may be provided on the back of the door 20. The fourth sealing ring is located inside the third metal protrusion, and when the door 20 closes the opening 111, the fourth sealing ring is in a sealing fit with the front surface of the body 10. When the door 20 closes the opening 111, the fourth sealing ring can seal the gap between the door 20 and the body 10, preventing leakage of steam, hot air, etc., and improving the energy efficiency and safety of the cooking equipment 100.

[0081] For example, the cooking device 100 may have functions such as steaming, baking, and microwaving. By setting a fourth sealing ring on the back of the door 20, the sealing performance of the cooking device 100 is improved, which makes it easier to ensure more precise control of temperature and humidity inside the cooking device 100 and ensure the cooking effect of the cooking device 100.

[0082] Furthermore, the dimension of the fourth sealing ring protruding from the back of the door body 20 is H6, and the dimension of the third metal protrusion protruding from the front surface of the body 10 is H5, where H5 < H6. That is, the dimension of the third metal protrusion protruding from the back of the door body 20 is smaller than the dimension of the fourth sealing ring protruding from the back of the door body 20. The smaller protrusion of the third metal protrusion from the back of the door body 20 facilitates the processing and shaping of the body 10 and makes cleaning of the cooking equipment 100 easier. The larger protrusion of the fourth sealing ring from the back of the door body 20 facilitates the mating of the fourth sealing ring with the body 10, improving the sealing effect of the cooking equipment 100. It also effectively isolates oil fumes and steam generated during cooking, preventing these fumes and steam from affecting the third metal protrusion, ensuring the mating of the first mating surface 12 and the second mating surface 21, preventing microwave leakage, and improving the safety of using the cooking equipment 100.

[0083] Optionally, the ratio of H6 / H5 is greater than or equal to 3 and less than or equal to 4. This facilitates the mating of the fourth sealing ring with the door 20, improving the sealing effect of the cooking equipment 100. The fourth sealing ring effectively isolates oil fumes and steam generated during cooking, preventing these substances from affecting the third metal protrusion, ensuring proper mating of the first mating surface 12 and the second mating surface 21, preventing microwave leakage, and improving the safety and lifespan of the cooking equipment 100.

[0084] The protruding size of the fourth sealing ring refers to the protruding size of the fourth sealing ring in its natural state, or the protruding size of the fourth sealing ring when it is not compressed by the body 10.

[0085] Combination Figure 3 and Figure 5 In some embodiments of this utility model, the cooking device 100 further includes a fifth sealing ring 30. The fifth sealing ring 30 is disposed on the body 10 or the door 20, and seals between the body and the door when the door 20 closes the opening 111, and is located outside the first mating surface 12 and the second mating surface 21. Specifically, the fifth sealing ring 30 may be disposed on the body 10 or the door 20. When the door 20 closes the opening 111, the fifth sealing ring 30 can seal the gap between the body 10 and the door 20, preventing leakage of steam, hot air, etc., and improving the energy efficiency and safety of the cooking device 100.

[0086] For example, the cooking device 100 may have functions such as steaming, baking, and microwaving. By setting a fifth sealing ring 30 on the front surface of the body 10, the sealing performance of the cooking device 100 is improved, which makes it easier to ensure more precise control of temperature and humidity inside the cooking device 100 and ensure the cooking effect of the cooking device 100.

[0087] In addition, the fifth sealing ring 30 is located on the outside of the first mating surface 12 and the second mating surface 21. For example, the first mating surface 12 and the second mating surface 21 can be metal surfaces. The fifth sealing ring 30 can reduce heat loss, improve the temperature stability of the cooking cavity 11, and prevent dust, fumes and other external objects from affecting the first mating surface 12 and the second mating surface 21.

[0088] Combination Figure 5 and Figure 8 In some embodiments of this utility model, the first mating surface 12 is configured as an annulus surrounding the opening 111, and the second mating surface 21 is configured as an annulus corresponding to the first mating surface 12. When the door 20 closes the opening 111, the second mating surface 21 and the second mating surface 21 fit together in the front-back direction and surround the opening 111, which can seal the gap between the door 20 and the body 10, and prevent microwaves from penetrating from the gap between the door 20 and the body 10 to the outside of the cooking equipment 100 during the operation of the microwave heating unit, thus affecting the user and further improving the safety performance of the cooking equipment 100.

[0089] Combination Figure 4 In some embodiments of this utility model, the body 10 also includes a metal inner liner, and a cooking cavity 11 with a front opening 111 is formed inside the metal inner liner. The periphery of the opening 111 is provided with an outwardly extending metal flange 15. The first mating surface 12 is provided on the metal flange 15, which facilitates the processing and forming of the body 10. When the microwave reaches the position of the first mating surface 12, the microwave cannot penetrate the metal part, which can prevent microwave leakage and improve the safety of the cooking equipment 100.

[0090] Combination Figure 5 In some embodiments of this utility model, the door 20 further includes a metal back plate 22, the periphery of which is opposite to the periphery of the opening 111 in the front-back direction, and a second mating surface 21 is disposed on the metal back plate 22. When microwaves reach the position of the second mating surface 21, microwaves cannot penetrate the metal parts, thus preventing microwave leakage and improving the safety of using the cooking equipment 100.

[0091] In some specific embodiments of this utility model, the body 10 may include a metal front frame, the door 20 may include a metal back plate 22, the first mating surface 12 may be provided on the metal front frame, and the second mating surface 21 may be provided on the metal back plate 22. After the door 20 closes the opening 111, the microwave heating unit works and generates microwaves. When the microwaves in the cooking cavity 11 reach the positions of the first mating surface 12 and the second mating surface 21, the first mating surface 12 and the second mating surface 21 come into contact. Since the microwaves cannot penetrate the metal parts, it can prevent the microwaves from leaking out from the gap between the door 20 and the body 10, thereby improving the safety of the cooking equipment 100.

[0092] In some embodiments of this utility model, the cooking device 100 also includes a burner, which is used to generate flue gas by burning gas. Specifically, the cooking device 100 can be connected to an external gas pipeline, and the high-temperature flue gas generated by the burner can enter the cooking chamber 11 to heat the food in the cooking chamber 11, thus overcoming the limitations of electric heating and improving the cooking efficiency of the cooking device 100.

[0093] The cooking apparatus 100 may also include a circulating fan, which drives the flue gas generated by the burner to circulate, thereby heating the items in the cooking chamber 11 and improving the heating uniformity and cooking effect of the cooking apparatus 100.
