[0020] 4. The mounting portion is provided with at least one set of connection holes, each set comprising a plurality of connection holes arranged in a height direction. Fasteners are inserted through the connection holes at the same height to securely connect the mounting portion to the door panel body. The fasteners are adjusted to penetrate the connection holes at different heights, thereby enabling the mounting portion to have multiple mounting positions at different heights. With this design, when the fastener penetrates the highest connection hole, the mounting portion is in the lowest mounting position; when the fastener penetrates the lowest connection hole, the mounting portion is in the highest mounting position. Thus, by adjusting the fasteners to penetrate the connection holes at different heights to connect the mounting portion to the door panel body, the mounting portion can have multiple mounting positions at different heights relative to the door panel body. This adjustment method is simple to operate and can also reduce the number of locations on the door panel body that are connected to the fasteners.

[0021] 5. The door panel body is provided with a connecting hole, and the mounting portion is provided with a vertically extending strip hole. A fastener passes through the strip hole and is fixedly connected to the connecting hole, thereby securing the mounting portion to the upper side of the door panel body.

This design allows for infinite adjustment of the entire strip hole height, providing more mounting positions and a wider adjustment range.

[0022] 6. A slot is provided on the back of the door panel body. The mounting portion is inserted vertically into the slot, with the back of the mounting portion located within the slot. This design allows the mounting portion to be hidden behind the door panel body, ensuring the aesthetics of the front side of the door panel body. Furthermore, by inserting the mounting portion vertically into the slot, the slot prevents the mounting portion from rocking left and right, forcing it to move only up and down, thus facilitating height adjustment. Finally, the back of the mounting portion is located within the slot, preventing it from protruding from the back of the door panel body and interfering with the door body during later assembly.

[0023] 7. The handle includes a downward-extending baffle and a connecting plate connecting the top of the baffle to the top of the mounting portion. A downward-facing handle slot is formed between the handle and mounting portion. When the mounting portion is in its highest position, the bottom of the baffle is located in front of the door panel body, and its bottom surface is lower than the top surface of the door panel body. This design simplifies the handle structure and facilitates its processing and molding. When the mounting portion is in its highest position, the bottom of the baffle is located in front of the door panel body, and its bottom surface is lower than the top surface of the door panel body, shielding the front of the door panel body and making the overall appearance of the dishwasher more harmonious and beautiful.

[0024] 8. The baffle extends downward from the top toward the side away from the mounting portion. This design allows the user's fingers to be inserted into the handle groove in an oblique manner to grasp the grip portion, thereby reducing the difficulty of the user's gripping the handle.

[0025] 9. A dishwasher door assembly comprises a door body and the aforementioned door panel, wherein the door panel has multiple mounting positions at different heights relative to the door body, and the door panel is fixed to the front side of the door body at one of the mounting positions.

[0041] Example 1

[0042] like Figures 1 to 5As shown, the dishwasher door panel of this embodiment includes a separately formed door panel body 100 and a handle 200. The handle 200 includes a grip portion 210 and a mounting portion 220. The mounting portion 220 has multiple mounting positions at different heights relative to the door panel body 100. The mounting portion 220 is fixed to the upper side of the door panel body 100 at a selected mounting position. The mounting position of the mounting portion 220 is adjusted to connect the handle 200 to the door panel body 100 to form door panels of different heights. This design allows the mounting portion 220 to be adjusted to different mounting positions at different heights to adjust the height of the door panel itself to different sizes. In this way, the overall height of the door panel can be adjusted as needed to adapt to the specifications of surrounding cabinets. Only one door panel is required to meet the decoration requirements of different kitchens, eliminating the need to carry multiple sizes of decorative panels after sales, which facilitates after-sales maintenance. In addition, by selecting a mounting position at a certain height for the mounting portion 220 to be fixed to the upper side of the door panel body 100, the relative position of the handle 200 and the dishwasher operating panel can be maintained unchanged, making it easier for users to open and close the door.

[0043] Specifically, the holding portion 210 in this embodiment includes a baffle 211 and a connecting plate 212, wherein one end of the baffle 211 is connected to the connecting plate 212, and the other end extends downward, and the mounting portion 220 is a vertically extending plate-like structure, and the connecting plate 212 is connected between the top of the baffle 211 and the top of the mounting portion 220, so that the holding portion 210 and the mounting portion 220 are connected to form a downward-opening U-shaped structure, that is, a handle groove with an opening facing downward is formed between the holding portion 210 and the mounting portion 220. Such a design allows the user to insert his fingers into the handle groove to hold the holding portion 210, and can simplify the structure of the handle 200, while also facilitating the processing and forming of the handle 200.

[0044] After the handle 200 in this embodiment is installed on the door panel body 100, the installation part 220 is located on the back of the door panel body 100, the connecting plate 212 is located above the door panel body 100, and the baffle 211 is located in front of the door panel body 100. With this design, the installation part 220 can be hidden on the back of the door panel body 100 to ensure the beauty of the front side of the door panel body 100.

[0045] In this embodiment, at least one group of connection holes is provided on the back of the door panel body 100, each group of connection holes includes a plurality of connection holes 110 arranged in the height direction, and the mounting portion 220 is connected to the connection holes 110 at the same height by fasteners 230 to be fixed to the upper side of the door panel body 100, wherein when the fasteners 230 are connected to the highest connection hole 110, the mounting portion 220 is in the highest mounting position (such as Figure 3 As shown), at this time, the door panel height is at its maximum, and when the fastener 230 is connected to the lowest connection hole 110, the mounting portion 220 is at the lowest mounting position (as shown). Figure 4As shown), at this time, the door panel height is at its minimum value. Therefore, by adjusting the fasteners 230 to connect with the connecting holes 110 at different heights, the mounting portion 220 can have multiple mounting positions at different heights relative to the door panel body 100 and form door panels of different heights. The adjustment method is simple to operate. In addition, the number of through holes 221 in the mounting portion 220 for the fasteners 230 to pass through can also be reduced.

[0046] Preferably, Figure 5 As shown, in this embodiment, the multiple connection holes 110 in each group of connection holes are evenly spaced, for example, at a spacing of 10 mm, and the maximum door panel height adjustment range is 50 mm. A group of connection holes is provided on each of the left and right sides of the back of the door panel body 100, symmetrically distributed about the vertical centerline of the door panel body 100. The mounting portion 220 is provided with at least one group of through holes, each group of through holes including two through holes 221 spaced apart on either side of the mounting portion 220. A fastener 230 passes through the left through hole 221 and is fixedly connected to one of the left connection holes 110, while another fastener 230 passes through the right through hole 221 and is fixedly connected to one of the right connection holes 110. The connection holes 110 connected to the left and right fasteners 230 are at the same height. This design improves the installation reliability and stability of the handle 200 and avoids the skew of the handle 200 caused by relying on a single group of connection holes.

[0047] Preferably, the connecting hole 110 is a threaded hole, and the fastener 230 is a screw. After the mounting portion 220 is fixed to the back of the door panel body 100, the head of the screw abuts against the back of the mounting portion 220. This design facilitates the disassembly and assembly of the fastener 230 and the connecting hole 110, and ensures the reliability of the connection between the handle 200 and the door panel body 100, with a better fixing effect.

[0048] In order to further enhance the connection reliability between the mounting portion 220 and the door panel main body 100, two groups of through holes are provided on the mounting portion 220, wherein the spacing between the two through holes 221 on the same side is the same as the spacing between the adjacent connecting holes 110 on the same side, so that the mounting portion 220 can be connected to the door panel main body 100 through more fasteners 230, thereby achieving the effect of enhancing the connection reliability between the mounting portion 220 and the door panel main body 100.

[0049] Furthermore, in this embodiment, a slot 120 is provided on the back of the door panel body 100. The slot 120 extends vertically and is open at its upper end to form a notch. A connecting hole 110 is provided on the bottom wall of the slot 120. The mounting portion 220 is vertically inserted into the slot 120 through the notch. By vertically inserting the mounting portion 220 into the slot 120, the slot 120 prevents the mounting portion 220 from rocking left and right, so that the mounting portion 220 can only move up and down, thereby facilitating height adjustment of the mounting portion 220. Furthermore, the back of the mounting portion 220 is located within the slot 120. This design prevents the back of the mounting portion 220 from protruding from the back of the door panel body 100 and interfering with the door body during subsequent assembly.

[0050] It should be noted that when the mounting portion 220 in this embodiment is in its highest mounting position, that is, when the mounting portion 220 is fixedly connected to the highest connection hole 110 via the fastener 230, the bottom of the baffle 211 is located in front of the door panel body 100, and the bottom surface of the baffle 211 is lower than the top surface of the door panel body 100. This design can shield the front of the door panel body 100, making the overall appearance of the dishwasher more harmonious and beautiful.

[0051] Preferably, the baffle 211 extends obliquely from top to bottom toward a side away from the mounting portion 220. Such a design allows the user's fingers to be inserted into the handle groove in an oblique manner to hold the grip portion 210, thereby reducing the difficulty of the user holding the handle 200.

[0052] It is understandable that in other embodiments of the present invention, the connecting hole may also be a snap-fit ​​hole, and the fastener may be a buckle fixedly connected to the mounting portion, and the buckle is connected to the snap-fit ​​hole to fix the mounting portion on the door panel body.

[0053] It is understandable that in other embodiments of the present invention, without considering aesthetics, the mounting portion may also be mounted on the front side of the door panel body, and the mounting method thereof may be set with reference to the above-mentioned embodiment.

[0054] It is understandable that in other embodiments of the present invention, the gripping portion may be a raised structure fixed to the front side of the mounting portion and located above the door panel body.

[0055] Example 2

[0056] Compared with the first embodiment, the difference of this embodiment is that the mounting portion is provided with at least one group of connection holes, each group of connection holes includes a plurality of connection holes arranged in the height direction, and the fasteners penetrate the connection holes at the same height to be fixedly connected to the door panel body, so that the mounting portion is fixed to the upper side of the door panel body, and the fasteners are adjusted to penetrate the connection holes at different heights so that the mounting portion has multiple mounting positions at different heights. With this design, when the fasteners penetrate the highest connection hole, the mounting portion is at the lowest mounting position, at which time the height of the door panel itself is at the minimum value; when the fasteners penetrate the lowest connection hole, the mounting portion is at the highest mounting position, at which time the height of the door panel itself is at the maximum value. Therefore, by adjusting the fasteners to penetrate the connection holes at different heights to connect to the door panel body, the mounting portion can have multiple mounting positions at different heights relative to the door panel body and form door panels of different heights. The adjustment method is simple to operate; in addition, the number of parts on the door panel body connected to the fasteners can be reduced.

[0057] Example 3

[0058] Compared to Examples 1 and 2, this embodiment differs in that: the door panel body is provided with a connecting hole, and the mounting portion is provided with a vertically extending strip hole. A fastener passes through the strip hole and is fixedly connected to the connecting hole, thereby securing the mounting portion to the upper side of the door panel body. The fastener can be adjusted at different locations through the strip hole to provide the mounting portion with multiple mounting positions at different heights. This design allows for infinite adjustment of the entire strip hole height, resulting in more mounting positions for the mounting portion and a wider adjustment range.
