[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0035] As people's living standards continue to improve, the steam-bake microwave oven has gradually become an indispensable cooking device in people's kitchens due to its comprehensive cooking functions and convenient usage. Figure 1 and Figure 2 As shown, this embodiment provides a cooking device, which includes an outer shell (not shown in the figure), an inner pot 2 and a heating tube 3. The inner pot 2 is arranged in the outer shell, and the heating tube 3 includes a heating end 31 and a cold end 32. The heating end 31 can generate heat to heat the food in the inner pot 2, and the cold end 32 does not generate heat. It is only connected to the inner pot 2 as a structure to fix the heating end 31, and can also prevent the local temperature of the inner pot 2 from being too high.

[0036] However, the presence of the cold end 32 causes the gap between the heating end 31 and the inner wall of the inner pot 2 to be too large, and the gap is close to the center of the inner pot 2. Since the space between the heating end 31 and the inner wall of the inner pot 2 cannot accommodate food, it is a waste of space, which makes it easy for users to directly observe the heating tube 3. The close distance between the heating end 31 and the food can also easily cause burns to the user, affecting the user experience.

[0037] The cooking device provided in this embodiment can be a steam-bake micro-in-one machine, or an oven or a steam oven, etc., as long as a heating tube 3 is provided in the inner pot 2 for heating.

[0038] like Figures 1 to 4As shown, to solve the above problems, in the cooking device provided in this embodiment, a receiving groove 21 is recessed into the inner wall of the inner pot 2, a heating tube 3 is connected to the inner pot 2, a cold end 32 is passed through the receiving groove 21 and partially located inside the receiving groove 21, and the heating end 31 is disposed inside the inner pot 2 and outside the receiving groove 21. To enable the heating tube 3 to generate heat, the cold end 32 is passed through the inner pot 2 and connected to a power source.

[0039] By setting a receiving groove 21 on the inner wall of the inner liner 2, sufficient space can be provided for the cold end 32 of the heating tube 3. When the cold end 32 passes through the receiving groove 21, the part of the cold end 32 located in the inner liner 2 is set in the receiving groove 21, so that the heating end 31 can be closer to the inner wall of the inner liner 2 within the range of the inner liner 2, reducing wasted space, and preventing users from being scalded by the heating tube 3, thereby improving user experience.

[0040] In this embodiment, the receiving groove 21 is recessed in the top surface of the inner pot 2. Since the heating tube 3 is close to the inner pot 2, the possibility of the user directly seeing the heating tube 3 is reduced, thereby improving the aesthetics.

[0041] In this embodiment, the receiving groove 21 includes a top wall 23 and side walls 22 surrounding the top wall 23 and arranged obliquely relative to the inner wall in which the receiving groove 21 is recessed, thereby forming an open structure for the receiving groove 21. The open structure means that the opening of the receiving groove 21 gradually increases in size as it moves away from the receiving groove 21. This structure facilitates forming the receiving groove 21 directly on the inner wall of the inner liner 2, simplifies processing, improves efficiency, and reduces cost.

[0042] Optionally, the cold end 32 is provided through the side wall 22 and fixedly connected to the side wall 22. On the one hand, even if the cold end 32 is long, the inclination allows the heating end 31 to be close to the inner wall of the inner pot 2, ensuring aesthetics and safety and reducing wasted space. On the other hand, the portion of the cold end 32 outside the inner pot 2 is located between the inner pot 2 and the outer shell. The inclination of the cold end 32 reduces the space required between the inner pot 2 and the outer shell, allowing the outer shell to be miniaturized and the size of the cooking device to be reduced.

[0043] Generally speaking, a sealing structure is provided between the cold end 32 and the side wall 22 to prevent water vapor in the inner liner 2 from leaking. The sealing structure is usually made of a polymer material such as rubber, and high temperature will affect the sealing performance and service life of the sealing structure. To solve the above problem, the heating end 31 includes a frame, and the angle between the plane where the frame is located and the cold end 32 is an obtuse angle. This structure can maximize the distance between the frame and the side wall 22 where the cold end 32 is fixed, thereby reducing the impact of heat during heating on the sealing structure. Moreover, the part of the cold end 32 located outside the inner liner 2 needs to be connected to electrical components, such as chips or power supplies. This structure can also keep the electrical components away from the frame, thereby extending the service life.

[0044] Furthermore, the plane where the frame is located is parallel to the inner wall of the inner pot 2 provided with the receiving groove 21. The frame is surrounded by the tube body of the heating end 31, which can increase the heating area and make the heat uniform, thereby improving the cooking effect.

[0045] like Figures 1 to 4 As shown, to facilitate installation of the heating tube 3, the cooking device further includes a mounting assembly 1, which is located outside the inner pot 2. The heating tube 3 also includes a fixing flange 33 and a connecting post 34 disposed on the fixing flange 33. The fixing flange 33 is located inside the receiving groove 21, and the connecting post 34 is inserted through the receiving groove 21 and fixedly connected to the connecting post 34. The mounting assembly 1 and the fixing flange 33 clamp the inner pot 2, thereby maintaining the stability of the heating tube 3. In this embodiment, the connecting post 34 is a stud, which passes through the inner pot 2 and the mounting assembly 1 and is threadedly connected to a fixing nut to press the mounting assembly 1 against the outer surface of the inner pot 2.

[0046] It's understandable that a steam-bake oven generates a significant amount of water vapor during use, and microwave leakage must be prevented. To ensure the tightness of the inner pot 2 during cooking, a seal is required where the heating tube 3 is located. To achieve this, the mounting assembly 1 includes a mounting plate 11 and a sealing member 12. The mounting plate 11 is fixedly connected to the connecting post 34, and the sealing member 12 is located between the mounting plate 11 and the inner pot 2. The mounting plate 11 compresses the sealing member 12 against the inner pot 2 to form a seal.

[0047] However, as the use time increases, the seal 12 will gradually age and deform, and it is easy to slide relative to the inner pot 2, thereby affecting the sealing performance, resulting in poor sealing and shielding effect against steam and microwaves.

[0048] like Figure 5 and Figure 6 As shown, in order to solve the above problems, the mounting assembly 1 includes a mounting plate 11 and a seal 12. The mounting plate 11 includes a plate body 111 and two retaining ribs 112. One side of the plate body 111 has a sealing surface. The two retaining ribs 112 are spaced apart on the sealing surface. The sealing surface and the two retaining ribs 112 form a sealing groove 115. The seal 12 is arranged in the sealing groove 115 and is sealed against the sealing surface. When the seal 12 is squeezed, the seal 12 is in contact with the two retaining ribs 112.

[0049] In the installation assembly 1, since the sealing surface of the installation plate 11 and the two retaining ribs 112 form a sealing groove 115, when the seal 12 is squeezed and deformed, it can abut against the retaining ribs 112, thereby wrapping the seal 12 and fixing it. Even if the seal 12 ages, it will not move, thereby ensuring the sealing and preventing the leakage of steam and microwaves.

[0050] In order to ensure that the mounting plate 11 and the inner liner 2 can fully squeeze the seal 12, it is necessary that the mounting plate 11 does not contact the inner liner 2 during the squeezing of the seal 12, otherwise the retaining rib 112 abuts the inner liner 2 to form a rigid fixation, and the seal 12 will no longer be squeezed. To achieve the above purpose, the height of the retaining rib 112 protruding from the sealing surface is less than the thickness of the seal 12. In other words, when the plate body 111 presses the seal 12 against the inner liner 2, the retaining rib 112 is spaced apart from the inner liner 2. At this time, by rotating the fixing nut, the pressure of the plate body 111 on the seal 12 can be gradually increased to improve the sealing performance. It is worth noting that it is necessary to stop the rotation of the fixing nut before the retaining rib 112 abuts the inner liner 2 to complete the fixation of the mounting assembly 1.

[0051] It is worth noting that the seal 12 can provide a seal between the mounting plate 11 and the inner liner 2. However, since the cold end 32 of the heating tube 3 passes through the inner liner 2, it is also necessary to prevent steam and microwaves from leaking between the cold end 32 and the inner liner 2, and between the cold end 32 and the seal 12. To achieve this, the positioning protrusion 122 is provided with a sealing hole 123, and the cold end 32 is inserted into the sealing hole 123 and has an interference fit with the sealing hole 123. Since the seal 12 is squeezed by the interference fit with the cold end 32 through the sealing hole 123, the sealing purpose is achieved. At the same time, the seal 12 can also seal the outer surface of the inner liner 2, thereby ensuring that steam and microwaves inside the inner liner 2 will not leak between the inner liner 2 and the cold end 32, thereby improving the sealing performance.

[0052] like Figure 5 and Figure 6 As shown, the seal 12 is provided with a positioning protrusion 122, and the sealing hole 123 is opened in the positioning protrusion 122. The mounting plate 11 is provided with a positioning hole 113 corresponding to the positioning protrusion 122. The positioning protrusion 122 is passed through the positioning hole 113 and has an interference fit with the positioning hole 113.

[0053] The sealing groove 115 of the mounting plate 11 is open, and the positioning protrusion 122 is inserted into the positioning hole 113 of the mounting plate 11, thereby preventing the seal 12 from moving laterally between the two retaining ribs 112. Furthermore, because the positioning protrusion 122 extends the axial dimension of the sealing hole 123, the contact area between the seal 12 and the cold end 32 is increased, thereby improving the sealing performance.

[0054] It is understandable that, because mounting plate 11 is relatively thin, the edge of positioning hole 113 of mounting plate 11 can easily embed into positioning protrusion 122 of seal 12, causing deformation or rupture of positioning protrusion 122, thus affecting sealing performance. To address this issue, the inner circumference of positioning hole 113 is connected to a flange 114 extending axially along positioning hole 113, with positioning protrusion 122 forming an interference fit with flange 114. The provision of flange 114 increases the contact area between positioning hole 113 and positioning protrusion 122 of seal 12, preventing deformation or rupture of positioning protrusion 122 while also increasing the contact area between the two and improving sealing performance and stability.

[0055] Furthermore, the flange 114 extends toward the seal 12. That is, the flange 114 is not visible on the outer surface of the mounting assembly 1, making the outer surface of the mounting plate 11 smoother as a whole, and not easy to scratch the operator during disassembly, thereby improving safety.

[0056] To enable real-time temperature monitoring within the inner pot 2, the cooking device also includes a temperature measuring member 4, comprising a clip 43 and a probe 41. Probe 41 extends through the side wall 22 and into the inner pot 2. The clip 43 is positioned outside the side wall 22 and between the seal 12 and the side wall 22. The wiring harness 42 of the probe 41 passes through the seal 12 and the mounting plate 11. To prevent deformation of the seal 12 caused by interference from the clip 43, which could lead to seal failure, a clearance groove 121 is provided on the side of the seal 12 facing away from the mounting plate 11. This clearance groove 121 allows the clip 43 to pass through, allowing the seal 12 to smoothly contact the side wall 22, ensuring a secure seal.

For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
