Description

Technical Field

[0001] This invention belongs to the field of dishwasher technology, specifically, it relates to a door structure and a dishwasher. Background Technology

[0002] A dishwasher is a device that uses nozzles to spray high-pressure washing water to clean dishes. A dishwasher generally includes a dishwasher body forming the washing chamber, a dish inlet at the front of the body, a door at the dish inlet, and dish racks inside the washing chamber. Currently, dishwashers on the market are available in floor-standing and countertop models. Floor-standing dishwashers mostly use a single door that flips down to open. To ensure that washing water does not leak from the gap between the door and the inner tub during washing, a sealing structure is installed between the door and the inner tub. The sealing structure of existing dishwashers consists of a sealing strip installed on the door or inner tub, along the edge of the door or inner tub.

[0003] Existing dishwashers include a door, door hinges, and an inner tub. The inner tub has an opening, and the door rotates by the rotation of the door hinges, thereby closing or opening the opening. The door rotates up and down, and a sealing strip is provided at the bottom of the door. The sealing strip is prone to peeling on both sides due to the opening and closing of the door or the impact of the shelf, which in turn affects the overall fixation of the sealing strip.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the technical problem in the prior art where the sealing strip peels off when the door or shelf is pressed against it, and to provide a door structure and a dishwasher.

[0036] like Figure 1 as well as Figure 2 As shown, one aspect of the present invention provides a door structure 1, including a door body 1 and a door hinge 2 fixed on the door body 1. A sealing strip 3 is provided at the bottom of the door body 1, and a pressing member 4 is provided on the door hinge 2 to press and fix the sealing strip 3 on the door body 1. The sealing strip is held between the pressing member 4 and the door body 1.

[0037] In an embodiment of the present invention, a pressing component 4 is provided on the door hinge 2. Through the cooperation between the pressing component 4 and the door hinge 2, the pressing component 4 can press and fix the sealing strip 3 to the door body 1, so as to prevent the sealing strip 3 from peeling off on both sides due to the opening and closing of the door or the impact of the shelf, thereby increasing the fixing strength of the sealing strip 3; the door hinge 2 is fixedly connected to the door body 1, and the door body 1 rotates with the rotation of the door hinge 2.

[0038] like Figure 1 as well as Figure 2 As shown in the embodiment of the present invention, a door liner 11 protruding inward relative to the door body 1 is provided on the inner side of the door body 1. A sealing strip 3 is embedded between the bottom edge of the door liner 11 and the door body 1. A side edge 12 opposite to one side of the door liner 11 is provided on one side of the door body 1. The door hinge 2 includes a rotatable hinge arm 21, and a protrusion 221 protruding on the side of the hinge arm 21 facing the door liner 11 is provided on the hinge arm 21.

[0039] The hinge arm 21 is fixed on the side 12 of the door body 1, and the pressing component 4 is provided on the protrusion 221.

[0040] In this embodiment of the invention, the inner side of the door body 1 refers to the side of the door body 1 facing the inner liner. A door liner 11 is provided on the inner side of the door body 1, located at the center of the inner side of the door body 1 and spaced a certain distance from each side of the door body 1. A flange is provided at the bottom of the door body 1, forming a groove structure between the flange and the bottom edge of the door liner 11. A sealing strip 3 is disposed within this groove structure, improving the fixing effect of the sealing strip 3 and reducing the probability of the sealing strip 3 falling off. The side 12 of the door body 1 is positioned opposite one side of the door liner 11, and the side 12 of the door body 1 is positioned opposite the door liner 11. A gap is provided between the linings 11. The door hinge 2 is fixed on the side 12 of the door body 1 to realize the rotation of both sides of the door body 1. The door hinge 2 includes a hinge seat and a hinge arm 21 hinged to the hinge seat. Since the hinge arm is fixedly connected to the side 12 of the door body 1, the hinge arm 21 can rotate on the hinge seat to drive the door body 1 to rotate. The pressing member 4 is provided on the protrusion 221. Through the cooperation between the pressing member 4 and the protrusion 221, the pressing member 4 can press and fix the sealing strip 3 on the door body 1, thereby realizing the fixation of the sealing strip 3.

[0041] It should be noted that the door hinge 2 is generally located on the two opposite sides 12 of the door body 1, and the sealing body extends to the two sides 12 of the door body 1. Therefore, the pressing component 4 mainly presses and fixes the two ends of the sealing strip 3.

[0042] The hinge arm 21 includes a hinge plate disposed opposite to the door liner 11, and the side 12 of the door body 1 is plate-shaped and installed parallel to the hinge plate.

[0043] In a preferred embodiment of the present invention, the hinge arm 21 is fixed to the side 12 of the door body 1 by screws 22. The screws 22 pass through the hinge arm 21 and form a protrusion 221 relative to the portion of the hinge arm 21 that protrudes toward the door liner 11.

[0044] In an embodiment of the present invention, the hinge arm 21 can be fixed to the side 12 of the door body 1 by commonly available fixing connectors, such as screws 22, bolts, nuts, etc. The hinge arm 21 is fixed to the side of the door body 1 by screws 22. The side 12 of the door body 1 is provided with a first mounting hole, and the hinge arm 21 is provided with a second mounting hole. The axis of the first mounting hole coincides with the axis of the second mounting hole, and the axis extends in the direction toward the door liner 11. After passing through the first mounting hole and the second mounting hole, the screw 22 extends toward the door liner 11 relative to the hinge arm 21 to form a protrusion 221. The protrusion 221 is provided on the pressing member 4. After passing through the first mounting hole and the second mounting hole, the screw 22 can be screwed to the nut.

[0045] like Figure 2 , Figure 3as well as Figure 4 As shown, in an embodiment of the present invention, the extrusion component 4 includes a body 41 with a certain extension length, the top of the body 41 has a support surface 421 for supporting the protrusion 221, and the bottom of the body 41 has an extrusion surface 434 for extruding against the outer wall of the sealing strip 3.

[0046] In an embodiment of the present invention, the extrusion member 4 has a body 41 with a certain extension length. The body 41 is located between the side 12 of the door body 1 and the door liner 11. The length of the body 41 extends from top to bottom, from the sealing strip 3 located at the bottom edge of the door liner 11 to the protrusion 221 of the side 12 of the door body 1. The bottom of the body 41 has an extrusion surface 434 for extruding the outer wall of the sealing strip 3, and the top of the body 41 has a support surface 421 for supporting the protrusion 221. When the extrusion member 4 is extruded and fixed, the seal is sealed. The sealing strip 3 has a certain elasticity, and the bottom of the door liner 11 and the door body 1 provide certain support for the sealing strip 3. The extrusion surface 434 can abut against the outer wall of the sealing strip 3. The protrusion 221 is provided on the support surface 421 of the body 41 and abuts against the support surface 421 of the body 41. The abutment between the protrusion 221 and the support surface 421 of the body 41 provides extrusion force for the extrusion surface 434 to extrude the outer wall of the sealing strip 3, so that the extrusion surface 434 can press and fix the sealing strip 3 between the bottom of the door body 1 and the door liner 11.

[0047] When installing the extrusion component 4, the extrusion surface 434 of the body 41 can be used to extrude the outer wall of the sealing strip 3 first. After manual extrusion, the protrusion 221 can be placed on the support surface 421 of the body 41 and abut against the support surface 421, thereby achieving the extrusion and fixation of the sealing strip 3.

[0048] like Figure 3 as well as Figure 4 As shown, in an embodiment of the present invention, a support protrusion 42 is provided on the side of the main body 41 in a direction opposite to the door body 1 relative to the main body 41, and a support surface 421 is provided along the upper surface of the support protrusion 42, and a protrusion 221 is provided on the upper surface of the support protrusion 42.

[0049] In an embodiment of the present invention, the main body 41 is provided with a support protrusion 42 protruding relative to the main body 41. The upper surface of the support protrusion 42 is a support surface 421. When the extrusion component 4 is extruded and fixed, the extrusion surface 434 provided at the bottom of the main body 41 is extruded and abutted against the outer wall of the sealing strip 3. After manual extrusion, the protrusion 221 is placed on the upper surface of the support protrusion 42 and abuts against the upper surface of the support protrusion 42. The abutment between the protrusion 221 and the upper surface of the support protrusion 42 provides extrusion force for the extrusion surface 434 to extrude the outer wall of the sealing strip 3.

[0050] It should be noted that the support protrusion is square. The length of the support protrusion in the extension direction can be considered as the width of the support protrusion, and the length consistent with the protrusion direction of the protrusion 221 can be considered as the length of the support protrusion. The fixing connector includes a screw 22 and a nut. The part of the screw 22 that protrudes from the hinge arm 21 is provided with a nut. After the nut and the screw 22 are screwed together, the part of the screw 22 that protrudes from the nut is the protrusion 221. The length of the support protrusion is the same as the protrusion length of the protrusion 221 or the length of the support protrusion is greater than the protrusion length of the protrusion 221, so that the protrusion 221 can completely abut against the upper surface of the support protrusion, thereby improving the support strength of the support protrusion 42. In addition, the edge of the support protrusion abuts against the nut, increasing the contact point of the pressing component 4, thereby improving the support strength of the support protrusion 42 and preventing the protrusion 221 from shifting or fatigue fracture due to insufficient support. Furthermore, the body 41 is provided with a reinforcing rib on the side opposite to the support protrusion. The reinforcing rib can increase the structural strength of the body 41 and further improve the support strength of the support protrusion 42.

[0051] like Figure 4 As shown, in an embodiment of the present invention, the upper surface of the support protrusion 42 extends upward relative to the support protrusion 42 to form a limiting stop 422 that limits the outer side wall of the protrusion 221.

[0052] In the implementation of the present invention, the upper surface of the support protrusion 42 extends upward to form a limiting stop 422, so that the space between the limiting stop 422 and the body 41 becomes the limiting space for the protrusion 221 on the upper surface of the support protrusion 42. The limiting stop 422 blocks the outer wall of the protrusion 221 to prevent the protrusion 221 from shifting position or falling off the support protrusion 42 when it comes into contact with the upper surface of the support protrusion 42.

[0053] The protrusion 221 is cylindrical, and the body 41 and the supporting protrusion 42 are provided with smooth grooves that fit the outer side wall of the protrusion 221, thereby enhancing the firmness of the protrusion 221 on the supporting protrusion 42.

[0054] In an embodiment of the present invention, two support protrusions 42 are provided on the side of the main body 41. The two support protrusions 42 are arranged vertically, and the extension length of the upper support protrusion 42 is less than the extension length of the lower support protrusion 42.

[0055] In an embodiment of the present invention, two support protrusions 42 are provided on the side of the top of the solid. The two support protrusions 42 are arranged vertically along the extension length direction of the body 41, so that the two support protrusions 42 at different heights of the body 41 abut against the upper surface of the support protrusions 42 at different heights through the protrusion 221, thereby changing the abutting force against the outer wall of the sealing strip 3. This allows the extrusion member 4 to adapt to sealing strips 3 of different shapes or elasticities, increasing the application range of the extrusion member 4.

[0056] For example, when the sealing strip 3 has a large elasticity, and the position of the protrusion 221 is fixed, the support protrusion 42 at a lower position abuts against the protrusion 221. Because the sealing strip 3 has a large elasticity, the pressure provided by the support protrusion 42 at a lower position to the extrusion surface 434 will be insufficient, and the extrusion surface 434 cannot press the sealing strip 3 tightly. Therefore, the position of the protrusion 221 can be adjusted so that the protrusion 221 abuts against the upper surface of the support protrusion 42 at a higher position, thereby increasing the extrusion pressure of the extrusion surface 434.

[0057] In an embodiment of the present invention, a pressing part 43 is provided at the bottom of the main body, which extends downward relative to the main body, and the lower side of the pressing part 43 is a pressing surface.

[0058] like Figure 4 As shown, in an embodiment of the present invention, the bottom of the body 41 is provided with two extrusion portions 43 that extend downward relative to the body. The two extrusion portions 43 are a first extrusion portion 431 and a second extrusion portion 432, respectively. An extrusion space 433 is formed between the first extrusion portion 431 and the second extrusion portion, which is clamped on the sealing strip 3. The side of each extrusion portion located in the extrusion space 433 is an extrusion surface 434.

[0059] In an embodiment of the present invention, a compression space 433 is formed between the first compression part 431 and the second compression part 432. Both the first compression part 431 and the second compression part 432 extend downward relative to the body 41. The direction of inclination can be determined according to different sealing strips 3. As long as the first compression part 431 and / or the second compression part 432 can compress the outer wall of the sealing strip 3, the inclination of the first compression part 431 and the second compression part 432 can definitely generate a downward compression force on the side wall of the sealing strip 3. The side surfaces of each compression part located in the compression space 433 become compression surfaces 434. During compression, the sealing strip 3 is placed in the compression space 433, and the first compression part 431 and / or the second compression part 432 press on the outer wall of the sealing strip 3.

[0060] A reinforcing rib is provided between the first extrusion part 431 and the body 41 to increase the structural strength of the first extrusion part 431 and further improve the extrusion strength of the first extrusion part 431.

[0061] In an embodiment of the present invention, the cross-section of the sealing strip 3 is triangular, and the inclination directions of the first extrusion part 431 and the second extrusion part 432 are consistent.

[0062] In an embodiment of the present invention, when the cross-section of the sealing strip 3 is triangular, the sealing strip 3 can be considered to include a first sidewall, a second sidewall, and a third sidewall. The first sidewall contacts the bottom edge of the door liner 11, and the second sidewall contacts the door body 1. The portion enclosed by the first sidewall and the second sidewall is placed in the compression space 433. The inclination directions of the first compression part 431 and the second compression part 432 are consistent, so that the first compression part 431 can press on the second sidewall, and the second compression part 432 can press on the first sidewall. Both the first compression part 431 and the second compression part 432 can compress the sealing strip 3, thereby increasing the compression strength of the compression part on the sealing strip 3.

[0063] It should be noted that the door liner 11 is square and includes two opposite sides 12, opposite top edges, and a bottom edge. The sealing strip 3 contacts the bottom edge of the bottom edge of the door liner 11. A notch is provided at the corner between the side 12 and the bottom edge of the door liner 11, so that the first gap formed between the side of the side 12 and the hinge arm 21 is smaller than the second gap formed between the side of the bottom edge of the door liner 11 and the hinge arm 21. The two ends of the sealing strip 3 extend outwards with a certain length relative to the bottom edge of the door liner 11. Since the bottom edge of the door liner 11 protrudes inwards relative to the door body 1, there is a gap between the two ends of the sealing strip and the door body 1, so that the sealing strip 3 can be placed in the compression space 433.

[0064] Furthermore, the inclination direction of the first extrusion part 431 and the second extrusion part 432 is consistent with the extended square of the support protrusion, so that the abutment force formed between the upper surface of the support protrusion and the protrusion 221 can be concentrated on the first extrusion part 431 and the second extrusion part 432, and the space occupied by the extrusion member 4 when fixing the sealing strip 3 is reduced.

[0065] In an embodiment of the present invention, a limiting member 44 is provided on the main body 41, and the limiting member 44 abuts against the hinge arm 21 and / or the door liner.

[0066] In the embodiments of the present invention, the limiting member 44 is used to limit the body 41 after the sealing strip 3 is squeezed and fixed, so as to prevent the body 41 from shifting and causing the squeezing strength of the squeezing surface 434 to decrease. In addition, the limiting member 44 can assist the support protrusion on the body 41 in supporting the protrusion 221, and increase the support strength of the upper surface of the support protrusion on the protrusion 221.

[0067] like Figure 3As shown, specifically, the limiting member 44 includes a protrusion 441 formed by the body 41 extending towards the hinge arm 21 or the door liner, the protrusion 441 abutting against the hinge arm 21 and / or the door liner; the limiting member 44 includes a protrusion 441 disposed on the body 41 that abuts against the hinge arm 21 and / or the door liner, the protrusion 441 may be square; more specifically, the limiting member 44 includes a first protrusion 441 located in a first gap and a second protrusion 441 located in a second gap, wherein the limiting member 44 may include two first protrusions 441 located in the first gap and two second protrusions 441 located in the second gap, the first protrusions 441 being disposed opposite to each other on both sides of the body 41, and the second protrusions 441 being disposed opposite to each other on both sides of the body 41, such that both sides of the body 41 abut against the door liner and the hinge arm 21 respectively.

[0068] The present invention also provides a dishwasher, including an inner tub and a door body 1 structure provided in the above technical solution. The door hinge 2 includes a hinge seat and a hinge arm 21 fixedly connected to the door body 1. The hinge arm 21 is hinged to the hinge seat, and the hinge seat is fixedly connected to the inner tub.

[0069] In an embodiment of the present invention, the dishwasher includes the door body 1 structure described above. The door hinge 2 of the door body 1 structure is provided with a pressing member 4. Through the cooperation of the pressing member 4 and the door hinge 2, the pressing member 4 can press and fix the sealing strip 3 to the door body 1, so as to avoid the sealing strip 3 from peeling off on both sides due to opening and closing the door or the shelf impact, thereby increasing the fixing strength of the sealing strip 3.

[0070] The door hinge 2 includes a hinge arm 21 and a hinge seat. The hinge seat is fixed to the inner tub of the dishwasher, and the hinge arm 21 is fixed to the door body 1. The door body 1 can be rotated on the inner tub by hinge arm 21 being hinged to the hinge seat, thereby opening or closing the inner tub.

[0071] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way.
