Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically to a heating tube fixing structure, a disinfection cabinet, and an integrated stove. Background Technology

[0002] The heating element fixing structure in the disinfection cabinet of an integrated stove is generally made of high-temperature resistant and flame-retardant ceramic material, which isolates the heating element wiring terminals. For example, a typical fixing structure includes a ceramic heating element socket and a heating element cover. The two ends of the heating element are installed into the heating element socket, the heating element cover is closed, and then the heating element socket and heating element cover are fixed with screws and nuts, thereby achieving the fixing and insulation of the heating element.

[0003] However, because ceramic materials are fragile, continuous tightening force from screws, or excessive tightening force, can cause the heating element socket and heating element cover to crack and break, failing to secure and insulate the heating element. Furthermore, having the screw and nut as two separate parts increases costs, and the limited space inside the disinfection cabinet can lead to installation difficulties and multiple steps.

[0023] Example 1

[0024] Combined with appendix Figure 1-6 This embodiment proposes a heating tube fixing structure, including a tube seat 1, a tube cover 2 and a buckle 3; the tube seat 1 is fixed inside the disinfection cabinet, and the tube cover 2 is located on one side of the tube seat 1; the tube seat 1 is provided with a groove 10 that opens to one side of the tube cover 2, and the groove 10 is used to accommodate the wiring terminal 50 of the heating tube 5.

[0025] The pipe cap 2 is provided with a first through hole 21, and the pipe seat 1 is provided with a second through hole 11 and a third hole 12. The first through hole 21 is connected to the second through hole 11, and the third hole 12 is located on the side of the second through hole 11 away from the pipe cap 2. The third hole 12 is connected to the second through hole 11 and there is an angle between the third hole 12 and the second through hole 11. The connecting hole walls of the second through hole 11 and the third hole 12 form an angle.

[0026] A mounting hole group is formed by the first through hole 21, the second through hole 11, and the third hole 12. At least two mounting hole groups are provided on a single heating tube fixing structure. The buckle 3 is elastic and includes a bottom edge 31 and an elastic edge 32. The elastic edge 32 is located on both sides of the bottom edge 31, and one end of the elastic edge 32 is connected to one end of the bottom edge 31. The end of the elastic edge 32 away from the bottom edge 31 is provided with a bent section 33. The elastic edge 32 passes through the first through hole 21 and the second through hole 11 so that the bent section 33 is inserted and elastically locked into the third hole 12, and the bottom edge 31 abuts against the tube cover 2.

[0027] In the heating tube fixing structure of this embodiment, the tube base 1 body can generally be fixed to the inside of the disinfection cabinet by screws or bolts or conventional connection structures. The buckle 3 includes a bottom edge 31 and an elastic edge 32, and is U-shaped in general. The two bent sections 33 extend away from the center line L of the buckle 3. The third hole 12 is also a through hole. The buckle 3 is preferably made of spring steel in one piece to ensure that the buckle 3 has good toughness. In other embodiments, the two bent sections 33 can also extend to different directions respectively. The third hole 12 can be a blind hole or a slot hole, as long as there is an angle between the hole wall of the second through hole 11 and the hole wall of the third hole 12, so as to provide a locking position for the bent section 33.

[0028] When installing the heating tube 5, simply insert the terminal 50 at the end of the heating tube 5 into the groove 10 of the tube seat 1, then cover it with the tube cover 2, and then insert the two elastic edges 32 of the buckle 3 into the two mounting hole groups respectively, that is, pass the elastic edges 32 of the buckle 3 through the first through hole 21 of the tube cover 2 and the second through hole 11 of the tube seat 1, and finally insert the bent section 33 into the third hole 12 and make the bottom edge 31 abut against the tube cover 2 to complete the installation of one end of the heating tube 5.

[0029] After the heating tube 5 is installed and fixed, the tube cover 2 is always located on one side of the tube seat 1, effectively isolating the wiring terminals 50 of the heating tube 5 from contact with other parts. When disassembly is required, simply press the elastic edges 32 on both sides to disengage the bent section 33 from the third hole 12, and then pull out the buckle 3 to complete the disassembly of the heating tube 5.

[0030] In a preferred embodiment, the elastic edge 32 of the buckle 3 is inclined away from the center line L of the buckle 3. Therefore, the buckle 3 has an outward expansion tendency, ensuring a more secure and tight fit when engaged with the first through hole 21 and the second through hole 11. Furthermore, the outwardly expanding elastic edge 32 can achieve an adaptive adjustment effect when inserted into the second through hole 11. It is understood that to ensure the elastic edge 32 can be inserted into the first through hole 21 and the second through hole 11, the diameters of the first through hole 21 and the second through hole 11 can be designed to be larger than the length of the bent section 33. If the outward expansion tendency of the elastic edge 32 is not guaranteed, the bent section 33 will not be able to be inserted into the third hole 12, thus affecting the tightness of the fit. However, the buckle 3 of this embodiment has an outward expansion tendency, which allows it to be tightened to both sides by tension after being inserted into the second through hole 11, and adaptively adjusts the expansion to allow the bent section 33 to be inserted into the third hole 12.

[0031] Understandably, even if the elastic edge 32 is not designed to be inclined away from the center line L of the buckle 3, there are implementation methods that ensure the bent section 33 is inserted into the third hole 12. That is, the length of the bent section 33 is designed to be greater than the diameter of the first through hole 21 and the second through hole 11. When the elastic edge 32 is inserted into the first through hole 21 and the second through hole 11, it is blocked by the inner walls of the first through hole 21 and the second through hole 11, and the bent section 33 will undergo elastic deformation, entering the first through hole 21 and the second through hole 11 in an inclined posture. When it moves to the third hole 12, since the bent section 33 is no longer in contact with the inner wall of the second through hole 11, the bent section 33 will restore its elastic deformation, thereby inserting into the third hole 12, realizing the connection between the tube seat 1 and the tube cover 2.

[0032] In a further embodiment, at least a portion of the bottom edge 31 protrudes towards the side where the bent section 33 is located to form a pressing section 34, which abuts against the pipe cap 2. In this embodiment, when the bent section 33 is inserted into the third hole 12, the pressing section 34 can precisely press down on the pipe cap 2, thereby limiting the position of the pipe cap 2 and preventing the position of the pipe cap 2 from shifting.

[0033] In summary, addressing the technical problems arising from the existing fixing methods for the heating tube 5, this invention improves the structure of the tube seat 1 and the tube cap 2, enabling them to be connected via a snap-fit ​​3. The snap-fit ​​3 does not exert excessive tightening force on the tube seat 1 and the tube cap 2, thus preventing the ceramic tube seat 1 and the tube cap 2 from cracking and breaking. Furthermore, the snap-fit ​​3 connection method makes the installation of the heating tube 5 quicker and more convenient.

[0034] Example 2

[0035] Combined with appendix Figure 1-6This embodiment proposes a disinfection cabinet, which includes the heating tube fixing structure described in Embodiment 1, and also includes a cabinet body 4 and a heating tube 5. The tube seat 1 is fixed on the cabinet body 4, and the two ends of the heating tube 5 are provided with wiring terminals 50. The two wiring terminals 50 are respectively inserted into the grooves 10 of the two sets of heating tube fixing structures.

[0036] In a further embodiment, a protective cover 51 is provided on the outside of the heating tube 5, and the protective cover 51 is fixedly connected to the cabinet 4. Thus, the protective cover 51 can prevent external objects from bumping into the heating tube 5, thereby protecting the heating tube 5.

[0037] In another embodiment, the side wall of the terminal 50 is provided with an outer flat portion 501, and the inner wall of the groove 10 is provided with an inner flat portion 101, with the outer flat portion 501 abutting against the inner flat portion 101. In this embodiment, the design of the outer flat portion 501 and the inner flat portion 101 can prevent the heating tube 5 from deflecting, thereby ensuring the stability of the heating tube 5.
