Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically, it relates to a door, a drum washing machine, and a method for assembling the door. Background Technology

[0002] In modern life, washing machines have become an essential household appliance. Washing machines include top-loading washing machines and front-loading washing machines. In the current technology, front-loading washing machines are generally front-opening. The front panel of the washing machine has a clothes loading port, and the door is located at the clothes loading port. The door is connected to the front panel of the front-loading washing machine by hinges. The door has a viewing window with glass. The viewing window not only seals the washing machine to prevent water from overflowing from the drum, but also allows the user to observe the washing process inside the drum at any time.

[0003] The door of a current drum washing machine consists of an inner frame and an outer frame, which are connected. This connection gap between the inner and outer frames results in an unsightly appearance. To address this, decorative elements are installed around the outer perimeter of the inner and outer frames to conceal the gap. These decorative elements include an upper decorative strip that covers the gap between the tops of the inner and outer frames. During the current door assembly process, the upper decorative strip is first slidably engaged with the top of the outer frame in a left-right direction. Then, the top of the inner frame is engaged between the upper decorative strip and the top of the outer frame. This requires adjusting the position of the heavier inner frame at the end of the assembly process, increasing the difficulty of door assembly.

[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 shortcomings of the prior art and provide a door body, a door body assembly method and a drum washing machine. By providing an assembly part for installing a decorative strip on the top of the outer frame outside the contact area, the outer frame and inner frame can be assembled during door body assembly, and then the upper decorative strip can be assembled on the top of the outer frame. This makes it possible to flexibly adjust the position of the lighter upper decorative strip when assembling the door body, without having to adjust the position of the heavier inner frame and outer frame, thereby reducing the difficulty of door body assembly and making door body assembly easier.

[0063] like Figure 1-11As shown, the present invention provides a door body, including an outer frame 11, an inner frame 12 and an upper decorative strip 13. The top of the outer frame 11 and the top of the inner frame 12 are connected to form a contact area 14. The upper decorative strip 13 covers the connection gap of the contact area 14. The top of the outer frame 11 outside the contact area 14 is provided with an assembly part 2 for installing the upper decorative strip 13.

[0064] In embodiments of the present invention, by providing an assembly part 2 for mounting a decorative strip 13 on the top of the outer frame 11 outside the contact area 14, the outer frame 11 and inner frame 12 can be assembled during the assembly of the door body 1, and then the upper decorative strip 13 can be assembled on the top of the outer frame 11. This allows the final assembly of the door body 1 to only require flexible adjustment of the position of the lighter upper decorative strip 13, without needing to adjust the positions of the heavier inner frame 12 and outer frame 11, thus reducing the difficulty of assembling the door body 1 and making the assembly of the door body 1 easier.

[0065] The contact area 14 may be a contact area 14 formed by the top of the outer frame 11 and the top of the inner frame 12 overlapping in the vertical direction, or a contact area 14 formed by the top of the outer frame 11 and the top of the inner frame 12 not overlapping in the vertical direction. For example, the rear end face of the outer upper flange 111 and the front end face of the inner upper flange 121 contact in the left and right direction to form a contact area 14.

[0066] This door 1 is suitable for drum washing machines. The specific structure of a drum washing machine is as follows:

[0067] Structure 1: The drum washing machine includes a casing 3, which includes a front panel with a clothes inlet. The door 1 is rotatably mounted on the front panel and covers the clothes inlet when the door 1 is closed.

[0068] Structure 2: The drum washing machine includes a casing 3, which includes a front panel with a clothes inlet. The door 1 is rotatably mounted on the front panel, and when closed, it covers the front panel and the clothes inlet. Covering the front panel and the clothes inlet with the door 1 makes the drum washing machine's appearance smoother and more streamlined, improving the product's aesthetics and making it easier for users to wipe and clean. Furthermore, the door 1 protects the front panel and the clothes inlet, preventing dust from entering the interior of the drum washing machine through the clothes inlet, thus preventing dust accumulation on the front panel and the clothes inlet, improving the product's cleanliness and hygiene, and enhancing the user experience.

[0069] The door 1 is square, specifically, the door 1 is rectangular. The vertical dimension of the door 1 is greater than the horizontal dimension of the door 1. The side of the housing 3 with the clothing loading port is the front side. The clothing loading port is located on the front side of the housing 3, and the front side of the housing 3 is the front panel.

[0070] The description of the front, back, left, and right sides of the door 1 below refers to the situation when the door 1 covers the clothing delivery opening.

[0071] like Figure 1-3 As shown in Figures 5 and 8, in an embodiment of the present invention, the contact area 14 is an overlapping area 141 formed by stacking the top of the outer frame 11 and the top of the inner frame 12 in the vertical direction.

Specifically, the outer frame 11 includes a vertically extending outer frame panel 11a, and the inner frame 12 includes a vertically extending inner frame panel 12a. The outer frame panel 11a and the inner frame panel 12a are square. The top of the outer frame panel 11a is bent backward to form an outer upper flange 111, and the top of the inner frame panel 12a is bent forward to form an inner upper flange 121. This achieves the opposite bending of the top of the outer frame panel 11a and the top of the inner frame panel 12a to form an outer upper flange 111 and an inner upper flange 121, respectively. The inner upper flange 121 is stacked on the outer upper flange 111 in the vertical direction to form an overlapping area 141. The mounting part 2 is disposed on the outer upper flange 111 outside the overlapping area 141, that is, the mounting part 2 is disposed at a distance between the outer upper flange 111 and the overlapping area 141.

[0073] Furthermore, the outer upper flange 111 includes a first horizontal portion 111b and a second inclined portion 133. The first horizontal portion 111b is located behind the first inclined portion 111c. The first horizontal portion 111b extends horizontally in the front-back direction. The first horizontal portion 111b bends downward to form a first inclined portion 111c that gradually slopes forward from top to bottom. The bottom end of the first inclined portion 111c is flush with the top of the outer frame panel 11a. The bottom end of the first inclined portion 111c and the top of the outer frame panel 11a are connected by a horizontally extending connecting wall. The outer upper flange 111, the connecting wall, and the outer frame panel 11a are integrally formed.

[0074] The inner upper flange 121 extends horizontally. Further, the first horizontal portion 111b includes a first part located at the rear end of the first horizontal portion 111b and a second part located at the front end of the first horizontal portion 111b. The front end portion of the inner upper flange 121 or the entire inner upper flange 121 is stacked on top of the first part in the first horizontal portion 111b to form an overlapping area 141. The assembly part 2 is provided on the first horizontal portion 111b outside the overlapping area 141 and has a certain distance from the overlapping area 141 in the front-back direction. That is, the assembly part 2 is provided on the second part, and the first part is connected to the first inclined portion 111c through the second part.

[0075] In an embodiment of the present invention, the assembly part 2 is a snap hole 21, which penetrates the outer upper flange 111 outside the overlapping area 141 in the vertical direction;

[0076] The upper decorative strip 13 covers the outer upper flange 111 and the inner upper flange 121, and a latching protrusion 132 is provided on the side of the outer upper flange 111 facing away from the overlapping area 141.

[0077] The protrusion 132 slides in the left and right direction and is inserted into the card hole 21.

[0078] In an embodiment of the present invention, specifically, the card hole 21 penetrates the first horizontal portion 111b outside the overlapping area 141 in the vertical direction, that is, the card hole 21 penetrates the second part of the first horizontal portion 111b in the vertical direction.

[0079] The upper decorative strip 13 includes: a second horizontal portion 131 extending in the front-back direction, the second horizontal portion 131 bending downward and forward to form a second inclined portion 133, the second horizontal portion 131 covering the inner upper flange 121 and the first horizontal portion 111b. Specifically, the second horizontal portion 131 is attached to the upper side of the inner upper flange 121, the second horizontal portion 131 is spaced apart from the first horizontal portion 111b, and the second inclined portion 133 is attached to the first inclined portion 111c, so that the upper decorative strip 13 can cover the inner upper flange 121, the overlapping area 141 and the outer upper flange 111, and increase the aesthetics of the door 1;

[0080] Furthermore, the latching protrusion 132 is provided on the side of the second horizontal part 131 facing the outward upper flange 111; the latching protrusion 132 slides into the latching hole 21 in the left and right direction, which can reduce the assembly strength of the upper decorative strip 13 and speed up the assembly of the upper decorative strip 13.

[0081] Furthermore, the first horizontal part 111b is provided with a positioning hole 211. The positioning hole 211 and the locking hole 21 are distributed in the left and right direction. The positioning hole 211 is elongated and extends a certain length in the front and back direction. The positioning hole 211 extends backward to the overlapping area 141 or extends into the overlapping area 141, as long as the locking hole 21 is outside the overlapping area 141.

[0082] The latching protrusion 132 includes a latching portion 132a and an abutting portion 132b, which protrude downward from the side of the upper decorative strip 13 toward the outwardly upturned edge 111. The latching protrusion 132 is inserted into the positioning hole 211 and slides from the positioning hole 211 into the latching hole 21 in a left-right direction to latch with the latching hole 21. The abutting portion 132b is located at the lower end of the latching portion 132a, and after passing through the latching hole 21, it abuts against the lower end face of the latching hole 21. Furthermore, the latching hole 21 is on the right side of the positioning hole 211, and the latching protrusion 132 slides from left to right into the latching hole 21.

[0083] The protrusion 132 is inverted T-shaped. The second horizontal part 131 of the upper decorative strip 13 extends vertically to form a snap-fit ​​part 132a. The free end of the snap-fit ​​part 132a is provided with an abutment part 132b, which is parallel to the second horizontal part 131. The positioning hole 211 guides the protrusion 132 into the snap-fit ​​part 132a, improving the accuracy of the protrusion 132 into the snap-fit ​​part 132a.

[0084] Furthermore, the left and right sides of the outer frame panel 11a are bent backward to form an outer left flange 113 and an outer right flange 114, respectively, and the left and right sides of the inner frame panel 12a are bent backward to form an inner left flange 123 and an inner right flange 124, respectively. The outer left flange 113, the outer right flange 114, the inner left flange 123, and the inner right flange 124 extend vertically.

[0085] The outer left flange 113 is attached to the outer side of the inner left flange 123, and the outer right flange 114 is attached to the outer side of the inner right flange 124. The outer left flange 113 is provided with a number of left locking protrusions evenly distributed in the vertical direction, and the outer right flange 114 is provided with a number of right locking protrusions 114a evenly distributed in the vertical direction. The inner left flange 123 is provided with a number of left locking holes 123a evenly distributed in the vertical direction, and the inner right flange 124 is provided with a number of right locking holes evenly distributed in the vertical direction.
