Description

Technical Field

[0001] This application relates to the technical field of door seals, and particularly to a door seal structure with good sealing performance. Background Art

[0002] A door seal is a strip-shaped item used to close doors or utensils, commonly seen in the sealing of doors and windows, playing roles such as sound insulation, dust prevention, anti-freezing, and heat preservation. The door seal is an important part of the steam oven structure. The door seal of a steam oven is usually made of silicone or special rubber materials, which can ensure that the high temperature and steam inside the steam oven do not leak during operation, and at the same time prevent external cold air from entering and affecting the cooking effect.

[0003] The door seal of a steam oven is usually snap-fitted and fixed to the door frame of the cabinet. To facilitate snapping the snap-fitting part of the door seal into the snap-fitting groove opened in the door assembly, a buffer cavity is provided in the snap-fitting part. When the snap-fitting part is snap-fitted and installed, due to the softness of the material of the door seal, when the snap-fitting part enters the snap-fitting groove, the buffer cavity is squeezed until the snap-fitting part enters the snap-fitting position of the snap-fitting groove, and the buffer cavity resumes, and the snap-fitting part is tightly snapped with the snap-fitting groove. However, the existing door seal has poor shock absorption effect, and the cabinet and the door are prone to damage after long-term collision, resulting in a reduced service life of the steam oven. Utility Model Content

[0004] In order to improve the service life of the steam oven, this application provides a door seal structure with good sealing performance.

[0005] A door seal structure with good sealing performance provided by this application adopts the following technical solutions:

[0006] A door seal structure with good sealing performance includes a snap-fitting part and a door latching part. The snap-fitting part is connected to the door latching part. The door latching part includes a latching member, a shock-absorbing member, a first bending member, and a second bending member. The latching member is connected to the snap-fitting part, the latching member is connected to the side wall of the shock-absorbing member, one end of the shock-absorbing member is connected to the first bending member, the end of the first bending member away from the shock-absorbing member is connected to the second bending member, the second bending member is connected to the shock-absorbing member, the shock-absorbing member, the first bending member, and the second bending member enclose to form a shock-absorbing cavity, the folding angle direction of the connection end of the first bending member and the second bending member faces the shock-absorbing cavity, and the shock-absorbing member is provided with an air outlet hole penetrating through the shock-absorbing cavity.

[0007] By adopting the above technical solution, the door seal prevents the door from directly contacting the box body. The shock-absorbing cavity shrinks to provide a buffering effect. When the door collides with the door seal, the door abuts against the shock-absorbing member. During the closing operation of the door and the box body, the door squeezes the shock-absorbing member, and the shock-absorbing member moves to push the first bent member to move, so that the connecting end of the first bent member and the second bent member is bent and moves toward the shock-absorbing cavity. The shock-absorbing cavity shrinks, and the gas inside the shock-absorbing cavity circulates through the air outlet holes, providing an effective shock-absorbing effect on the collision of the door, reducing the occurrence of defects, and improving the service life of the steam oven; and, by setting the first bent member and the second bent member to guide the telescopic direction of the shock-absorbing cavity, reducing the uncertainty of the telescopic direction of the shock-absorbing cavity. When the shock-absorbing cavity shrinks, multiple overlaps occur on the cavity wall of the shock-absorbing cavity, resulting in limited extrusion of the shock-absorbing member and preventing the door from closing with the box body. Then, there is a possibility of steam leakage and water leakage in the steam oven, thereby improving the service life of the steam oven.

[0008] Optionally, the engaging portion is connected to the shock-absorbing member.

[0009] By adopting the above technical solution, the engaging portion can support the shock-absorbing member, thereby reducing the possibility of the shock-absorbing member breaking under pressure and improving the structural stability of the shock-absorbing member.

[0010] Optionally, the engaging portion includes a first connecting member, a second connecting member, and a clamping member. The first connecting member is connected to the side wall of the shock-absorbing member, the second connecting member is connected to the overlapping member, the first connecting member is connected to the clamping member, the second connecting member is connected to the clamping member, the clamping member is provided with a buffer cavity, the cavity wall of the buffer cavity is penetrated with air holes, a transition cavity is formed between the first connecting member, the second connecting member, the clamping member and the shock-absorbing member, and a through groove is formed on the cavity wall of the transition cavity. The transition cavity is communicated with the buffer cavity through the through groove.

[0011] By adopting the above technical solution, when the door covers the box body, the door presses on the overlapping member and the shock-absorbing member, thereby squeezing the buffer cavity and the shock-absorbing cavity. The buffer cavity and the shock-absorbing cavity shrink to provide a buffering effect for the installation of the door. The gas inside the buffer cavity circulates through the air holes, the gas inside the shock-absorbing cavity circulates through the air outlet holes, and the gas in the transition cavity is communicated with the buffer cavity through the through groove. The buffer cavity, the shock-absorbing cavity and the transition cavity cooperate with each other to provide an effective shock-absorbing effect on the collision of the door, reduce the occurrence of defects, and extend the service life of the steam oven.

[0012] Optionally, continuous broken-line protrusions are provided on both opposite sides of the engaging portion.

[0013] By adopting the above technical solution, the broken-line protrusions form a multi-stage lip structure, and each lip structure has a sealing effect, enabling the engaging portion and the door frame to form a multi-stage sealing function with each other, thereby improving the sealing effect at the connection position between the door seal and the box body.

[0014] Optionally, a first positioning portion is connected to one end of the overlapping member away from the shock-absorbing member, and a second positioning portion is connected to one end of the shock-absorbing member close to the second bending member.

[0015] By adopting the above technical solution, the first positioning portion and the second positioning portion pre-position the installation position of the engaging portion, enabling the engaging portion to be accurately clamped at the door frame position of the box body. Moreover, the first positioning portion and the second positioning portion provide a fixing effect on the engaging portion. Under the action of the first positioning portion and the second positioning portion, the door frame and the engaging portion are tightly clamped, thereby improving the connection stability between the door frame and the door seal.

[0016] Optionally, the second positioning portion is inclined, and one end of the second positioning portion away from the shock-absorbing member faces the engaging portion.

[0017] By adopting the above technical solution, when the second positioning portion pre-positions the installation position of the engaging portion, one end of the second positioning portion away from the shock-absorbing member faces the engaging portion, causing the second positioning portion to clamp the door frame under the action of the engaging portion, thereby further improving the connection stability between the door frame and the door seal.

[0018] Optionally, anti-slip stripes are connected to one side of the shock-absorbing member away from the first bending member.

[0019] By adopting the above technical solution, the friction between the box door and the shock-absorbing member is increased, enabling the shock-absorbing member to fit flatly on the box door, and improving the sealing effect at the connection position between the box door and the door seal.

[0020] Optionally, an inner groove that cooperates with the box door is formed between one side of the shock-absorbing member and one side of the overlapping member, and the inner groove is located on the side of the overlapping member away from the engaging portion.

[0021] By adopting the above technical solution, the inner groove pre-positions the closing position of the box door, enabling the box door to be accurately closed at the connection position between the shock-absorbing member and the overlapping member; meanwhile, the contact area between the door seal and the box door at the bending position is increased, improving the sealing effect.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The door seal prevents the door from directly contacting the box body. It uses the contraction of the shock-absorbing cavity to provide a buffering effect. When the door collides with the door seal, the door abuts against the shock-absorbing member. During the closing operation of the door and the box body, the door squeezes the shock-absorbing member, and the shock-absorbing member moves to push the first bent member to move, causing the connecting end of the first bent member and the second bent member to bend and move towards the shock-absorbing cavity. The shock-absorbing cavity contracts, and the gas inside the shock-absorbing cavity circulates through the air outlet holes, providing an effective shock-absorbing effect on the collision of the door, reducing the occurrence of defects, and improving the service life of the steam oven; and, by setting the first bent member and the second bent member to guide the telescopic direction of the shock-absorbing cavity, reducing the uncertainty of the telescopic direction of the shock-absorbing cavity. When the shock-absorbing cavity contracts, multiple overlaps occur on the cavity wall of the shock-absorbing cavity, resulting in limited extrusion of the shock-absorbing member and preventing the door from closing with the box body. Then, there is a possibility of steam leakage and water leakage in the steam oven, thereby improving the service life of the steam oven;

[0024] 2. When the door covers the box body, the door presses on the overlapping member and the shock-absorbing member, thereby squeezing the buffer cavity and the shock-absorbing cavity. The buffer cavity and the shock-absorbing cavity contract to provide a buffering effect for the installation of the door. The gas inside the buffer cavity circulates through the air permeation holes, the gas inside the shock-absorbing cavity circulates through the air outlet holes, and the gas in the transition cavity is connected to the buffer cavity through the through groove. The buffer cavity, the shock-absorbing cavity, and the transition cavity cooperate with each other to provide an effective shock-absorbing effect on the collision of the door, reducing the occurrence of defects, and extending the service life of the steam oven;

[0025] 3. When the second positioning portion pre-positions the installation position of the engaging portion, the end of the second positioning portion away from the shock-absorbing member faces the engaging portion, so that the second positioning portion clamps the door frame under the action of the engaging portion, thereby further improving the connection stability between the door frame and the door seal.

[0032] The following is further described in detail in conjunction with the attached Figures 1-4 This application is further described in detail.

[0033] The embodiment of this application discloses a door seal structure with good sealing performance.

[0034] Refer to Figure 1 And Figure 2 A door seal structure with good sealing performance includes a clamping portion and a door lapping portion. The clamping portion is connected to the door lapping portion. The door lapping portion includes a lapping member 1, a shock-absorbing member 11, a first bending member 12 and a second bending member 13. One side of the lapping member 1 is fixedly connected to one side of the clamping portion. One end of the lapping member 1 is fixedly connected to the side wall of the shock-absorbing member 11. One end of the shock-absorbing member 11 is fixedly connected to one end of the first bending member 12. The end of the first bending member 12 far from the shock-absorbing member 11 is fixedly connected to one end of the second bending member 13. The end of the second bending member 13 far from the first bending member 12 is fixedly connected to the end of the shock-absorbing member 11 far from the first bending member 12. The extended cross-section of the shock-absorbing member 11 is arc-shaped. The first bending member 12 and the second bending member 13 are located within the arc surface range of the shock-absorbing member 11. The shock-absorbing member 11, the first bending member 12 and the second bending member 13 enclose a shock-absorbing cavity 14. The folding angle direction of the connecting ends of the first bending member 12 and the second bending member 13 faces the shock-absorbing cavity 14. Refer to Figure 3 A bending groove 15 is provided at the connection between the first bending member 12 and the second bending member 13. The bending groove 15 is located outside the shock-absorbing cavity 14. The shock-absorbing member 11 is provided with an air vent 111 that penetrates the shock-absorbing cavity 14.

[0035] When closing the box door, the box door collides with the shock absorber 11, and the box door squeezes the shock absorber 11. The shock absorber 11 moves to push the first bent part 12 to move, so that the connecting end of the first bent part 12 and the second bent part 13 bends with the bending groove 15 as the bending point and moves towards the shock absorption cavity 14. The shock absorption cavity 14 shrinks, and the gas inside the shock absorption cavity 14 circulates through the air outlet hole 111. Subsequently, the box door collides with the overlapping part 1 again, reducing the possibility of the box door directly colliding with the box body, providing an effective shock absorption effect for the collision of the box door, reducing the generation of defects, and improving the service life of the steam oven; and, by setting the first bent part 12 and the second bent part 13 to guide the telescopic direction of the shock absorption cavity 14, reducing the uncertainty of the telescopic direction of the shock absorption cavity 14. When the shock absorption cavity 14 shrinks, multiple overlaps occur on the cavity wall of the shock absorption cavity 14, resulting in limited extrusion of the shock absorber 11 and the inability of the box door and the box body to close, and then the possibility of steam leakage and water leakage in the steam oven, thereby improving the service life of the steam oven.

[0036] Referring to Figure 1 and Figure 2 , the engaging part includes a first connecting member 2, a second connecting member 21 and a clamping member 22. One end of the first connecting member 2 is fixedly connected to the side wall of the shock absorber 11, so that the first connecting member 2 supports the shock absorber 11, thereby reducing the possibility of the shock absorber 11 being broken under pressure and improving the structural stability of the shock absorber 11. One end of the second connecting member 21 is fixedly connected to the overlapping part 1. The length direction of the first connecting member 2 is parallel to the length direction of the second connecting member 21. The end of the first connecting member 2 away from the shock absorber 11 is fixedly connected to the side wall of the clamping member 22. The end of the second connecting member 21 away from the overlapping part 1 is fixedly connected to the side wall of the clamping member 22. The clamping member 22 is provided with a buffer cavity 23. The length direction of the buffer cavity 23 is parallel to the length direction of the shock absorption cavity 14. The cavity wall of the buffer cavity 23 is penetrated with air holes 24. The air holes 24 are located on the side of the clamping member 22 away from the first connecting member 2. A transition cavity 25 is formed between the first connecting member 2, the second connecting member 21, the clamping member 22 and the shock absorber 11. The length direction of the transition cavity 25 is parallel to the length direction of the shock absorption cavity 14. The cavity wall of the transition cavity 25 is provided with a through groove 26. The transition cavity 25 is communicated with the buffer cavity 23 through the through groove 26.

[0037] When the door of the box is closed on the box body, the door of the box presses on the overlapping part 1 and the shock-absorbing part 11, thereby squeezing the buffer cavity 23 and the shock-absorbing cavity 14. The buffer cavity 23 and the shock-absorbing cavity 14 contract to provide buffering for the installation of the door of the box. The gas inside the buffer cavity 23 circulates through the air-permeable hole 24, and the gas inside the shock-absorbing cavity 14 circulates through the air outlet hole 111. The gas in the transition cavity 25 is connected to the buffer cavity 23 through the through groove 26, so that the gas in the transition cavity 25 flows into the buffer cavity 23, and then the gas flows through the air-permeable hole 24 on the buffer cavity 23. The buffer cavity 23, the shock-absorbing cavity 14 and the transition cavity 25 cooperate with each other to provide an effective shock-absorbing effect on the collision of the door of the box, reduce the generation of defects, and extend the service life of the steam oven.

[0038] To improve the sealing effect at the connection position between the door seal and the box body, continuous folded line protrusions 3 are provided on both opposite sides of the clamping part 22, and the folded line protrusions 3 are located on both sides of the first connecting part 2 in the length direction.

[0039] One end of the overlapping part 1 away from the shock-absorbing part 11 is fixedly connected with a first positioning part 4. One side of the overlapping part 1 close to the first connecting part 2 and one side of the first positioning part 4 are on the same plane. When the clamping part 22 is clamped in the door frame, one side of the overlapping part 1 close to the first connecting part 2 fits against the door frame, and the first positioning part 4 on the same plane as the overlapping part 1 fits against the door frame. One end of the shock-absorbing part 11 close to the second bending part 13 is fixedly connected with a second positioning part 41, and the second positioning part is located at one end of the overlapping part 1 close to the first connecting part 2.

[0040] The first positioning part 4 and the second positioning part 41 pre-position the installation position of the engaging part, so that the engaging part can be accurately clamped at the door frame position of the box body. Moreover, the first positioning part 4 and the second positioning part 41 provide a fixing effect on the engaging part. Under the action of the first positioning part 4 and the second positioning part 41, the door frame and the engaging part are tightly clamped, improving the connection stability between the door frame and the door seal.

[0041] When the second positioning part 41 pre-positions the installation position of the engaging part, to further improve the connection stability between the door frame and the door seal, the second positioning part 41 is inclined, and one end of the second positioning part 41 away from the shock-absorbing part 11 faces the first connecting part 2.

[0042] Refer to Figure 2 and Figure 4 ., an anti-slip stripe 5 is connected to the side of the shock-absorbing part 11 away from the first bending part 12, and the anti-slip stripe 5 is located at one end of the shock-absorbing part 11 away from the first connecting part 2 and the overlapping part 1. When the door of the box is closed on the box body, the friction between the door of the box and the shock-absorbing part 11 is increased, so that the shock-absorbing part 11 can fit flatly on the door of the box, improving the sealing effect at the connection position between the door of the box and the door seal.

[0043] One side of the shock absorber 11 away from the first bending member 12 and one side of the overlapping member 1 away from the second connecting member 21 form an inner groove that cooperates with the door of the box, and the inner groove is located on the side of the overlapping member 1 away from the clamping member 22.

[0044] When the door of the box is closed on the box body, the door of the box fits at the inner groove, and the inner groove pre-positions the closing position of the door of the box, so that the door of the box can be accurately closed at the connection position of the shock absorber 11 and the overlapping member 1; at the same time, the contact area between the door seal and the door of the box at the bending position is increased, improving the sealing effect.

[0045] The implementation principle of a door seal structure with good sealing performance in the embodiment of the present application is as follows: the engaging portion is snapped into the engaging groove of the box body for fixation, and the first positioning portion 4 and the second positioning portion 41 pre-position the installation position of the clamping member 22. When the door of the box is closed on the box body, the door of the box abuts against the shock absorber 11, and the door of the box presses the shock absorber 11. The shock absorber 11 moves to push the first bending member 12 to move, so that the connecting end of the first bending member 12 and the second bending member 13 bends with the bending groove 15 as the bending point, and the connecting end of the first bending member 12 and the second bending member 13 moves towards the inside of the shock absorption cavity 14, guiding the telescopic direction of the shock absorption cavity 14, reducing the possibility of the telescopic direction of the shock absorption cavity 14 being uncertain. When the shock absorption cavity 14 contracts, the gas inside the shock absorption cavity 14 circulates through the air outlet 111, providing an effective shock absorption effect for the collision of the door of the box, reducing the generation of defects, and improving the service life of the steam oven.

[0046] The above are all preferred embodiments of the present application. This embodiment is only an explanation of the present application and does not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
