Description

Technical Field

[0001] The present invention belongs to the technical field of dishwashers, and in particular relates to a cover device of a dishwasher and a dishwasher having the cover device. Background Art

[0002] The drawer-type dishwasher's inner chamber is open at the top, connecting it to the interior of the cabinet 10. Therefore, a sealed lid is required to prevent water or steam from escaping from the top and entering the bottom of the cabinet 10 during operation. Because the motor is mounted at the bottom of the cabinet 10, water or steam escaping from the inner chamber can easily short-circuit the motor's power supply circuit, and in severe cases, burn out the motor. Furthermore, without a lid, heat can easily dissipate during the drying cycle, prolonging drying time, wasting energy, and increasing customer costs.

[0003] During operation, a drawer-type dishwasher's cover moves by sliding the drawer, closing the inner container and sealing it. When the drawer is pulled out, the cover detaches from the container, allowing dishes to be removed and placed in. Currently, the cover of a drawer-type dishwasher primarily operates by sliding the drawer. This also results in inaccurate positioning between the cover and the inner container, leading to a poor seal. This can easily cause the dishwasher to malfunction or even fail.

[0085] See Figure 1-Figure 36 , an embodiment of the dishwasher cover device of the present invention, includes a cover 7 that seals against the inner container 30 of the dishwasher, two support plates 8 disposed on either side of the cover 7 for supporting the cover 7, and a drive mechanism 9 for supporting and driving the support plates 8. The support plates 8 are mounted on the cover 7. The drive mechanism facilitates precise control of the drive mechanism 9's movement, ensuring precise and accurate movement of the cover 7 during opening and closing, and improving the seal between the cover 7 and the inner container 30. The support plates 8 are supported on either side of the cover 7, and the drive mechanism 9 drives the support plates 8, resulting in a simple structure. The drive mechanism 9 activates upon receiving a command from a computer board, allowing the drawer to be pulled out when the cover 7 is opened. When the cover 7 is closed, the inner container 30 is sealed against the cover 7, preventing the drawer 20 from being opened. This prevents accidental operation of the drawer 20, which could cause burns due to high temperatures, and improves safety.

[0086] See also Figure 7 and Figure 12 As shown, the support plate 8 includes a support body 80 and a plurality of fixing parts 85 arranged on the support body 80 and assembled with the cover plate 7. The support body 80 is an inverted triangular frame structure. Vertical support ribs 87 are provided in the middle of the frame structure, and the lower end of the support body 80 is connected to the driving structure 9. By setting the support body 80 as an inverted triangular frame structure, the support for the cover plate 7 and the transmission of the driving force are guaranteed while reducing the self-weight of the support body 80.

[0087] See also Figure 16 As shown, the drive structure 9 includes a drive body 91 and a drive rod 92 disposed on the drive body 91 and extending upward, wherein the drive rod 92 is connected to the lower end of the support plate 8. The drive body 91 is fixed to the housing 10. The drive rod 92 is driven by a motor to move up and down, transmitting force to the support plate 8 and then upward to the cover plate 7, thereby pushing the cover plate 7 to open or close.

[0088] See also Figure 17As shown, a connector 921 is provided at the upper end of the driving rod 92. The connector 921 has a connector body 9211, and a mounting plate 9212 is provided on the side of the connector body 9211 near the support plate 8. A mounting opening 83 is provided on the support plate 8, and the mounting plate 9212 is located at the mounting opening 83. The mounting plate 9212 cooperates with the mounting opening 83 to achieve the connection and assembly between the driving rod 92 and the support plate 8. When the cover plate 7 is opened, the front end of the cover plate 7 is tilted a greater distance than the rear side. Due to the pulling out and pushing back of the drawer 20, the support plate 8 can rotate at a smaller angle while moving upward, thereby achieving a larger opening distance of the front end of the cover plate 7. Therefore, the mounting opening 83 is provided to be rotatable relative to the mounting plate 9212.

[0089] See also Figure 15-17 As shown, in order to increase the stability of the mounting plate 9212 and the mounting port 83, a plurality of first mounting portions 9213 are provided along the front and rear sides of the mounting plate 9212, and a second mounting portion 9214 is provided along the end of the first mounting portion 9213 and extends outwardly. The second mounting portion 9214 is located on the front or rear side of the connector body 9211, and two first mounting portions 9213 and second mounting portions 9214 are provided on the front and rear sides of the connector body 9211. A limiting groove 831 matching the first mounting portion 9213 is provided at the mounting port 83, and four limiting grooves 831 are provided at the mounting port 83; by providing the limiting groove 831, it is beneficial to ensure the stability of the mounting plate 9212 and the mounting port 83 after assembly.

[0090] To further enhance structural strength, a plurality of second mounting portions 9214, located at the front or rear end of mounting plate 9212, are provided on the outside of the plurality of second mounting portions 9214. These portions are connected to the second mounting portions 9214. These reinforcing plates 9215 are provided with stopper protrusions protruding toward connector 9211, and the connector body 9211 is provided with stopper grooves that match the stopper protrusions. The provision of reinforcing plates 9215 and the coordination between these plates and connector body 9211 enhance the structural strength of connector 9211 and ensure stable engagement with mounting opening 83.

[0091] To allow for slight relative rotation between the connector 921 and the mounting opening 83, arc-shaped support portions 9216 are provided at the upper and lower ends of the mounting plate 9212. The upper and lower ends of the mounting opening 83 are arc-shaped to match the support portions 9216, with the upper and lower ends of the mounting opening 83 forming two arc segments on the same circle. To increase the mating area with the support portions 9216 and prevent the connector 921 from separating from the mounting opening 83 due to inward and outward deviation of the support portions 9216, an inwardly extending upper inner mating edge 832, an outwardly extending upper outer mating edge 833, and an inwardly extending lower mating edge 834 are provided at the lower end of the mounting opening 83.

[0092] See also Figure 10 and Figure 18 As shown, a front extension portion 84 extending forward is provided at the upper end of the support body 80, and a front limit plate 105 is provided at the front end of the dishwasher cabinet 10, and the front extension portion 84 is located between the side panel of the cabinet 10 and the front limit plate 105; so that in the inward and outward directions, the front extension portion 84 can only be between the side panel of the cabinet 10 and the front limit plate 105, playing an inward and outward upper limit role for the front end of the support plate 8, thereby avoiding the support plate 8 from shaking in the inward and outward directions during the up and down pushing process, where "inward" refers to the direction close to the cover plate 7, or the direction close to the cabinet 10; support plates 8 and drive structures 9 are provided on both the left and right sides of the cover plate 7.

[0093] In order to speed up the assembly between the support plate 8 and the cover plate 7, a sliding assembly structure is provided between the support plate 8 and the cover plate 7. The sliding assembly structure includes a sliding groove 81 provided on the support plate 8 and a sliding block 71 provided on the cover plate 7. The provision of the sliding assembly structure enables sliding assembly between the support plate 8 and the cover plate 7, which is conducive to improving assembly efficiency.

[0094] See also Figures 8-11As shown, the sliding block 71 includes a slide plate 711 and a connecting plate 712 connecting the cover plate 7 and the slide plate 711; the sliding groove 81 includes a slide groove 811 for accommodating the slide plate 711, an extension port 812 for the slide plate 711 to extend, and an avoidance channel 813 for avoiding the connecting plate 712; wherein the avoidance channel 813 is connected to the extension port 812, so that after the slide plate 711 extends from the extension port 812, the connecting plate 712 is located in the extension port 812; then the support plate 8 and the cover plate 7 move relative to each other, so that the sliding block 71 When the support plate 8 moves upward along the sliding groove 81, the connecting plate 712 moves in the avoidance channel 813. Preferably, the avoidance channel 813 is provided at the middle position of the bottom of the sliding groove 811, and the two parts separated by the avoidance channel 813 at the bottom of the sliding groove 811 are respectively blocked by the two parts separated by the connecting plate 712 on the inner side of the slide plate 711. The extension opening 812 is provided at the lower end of the bottom of the sliding groove 811. By setting the slide plate 711 to slide in the sliding groove 811, the front and rear side walls of the sliding groove 811 form a limit and guide function for the slide plate 711. When the support plate 8 is assembled to the cover plate 7, the support plate 8 is brought close to the cover plate 7, and the slide plate 711 is extended from the extension opening 812. Then, the sliding block 71 is moved upward along the sliding groove 81. Specifically, the slide plate 711 slides upward in the sliding groove 811, and at the same time, the slide plate 711 slides in the sliding groove 811. When the sliding block 71 reaches the upper end of the sliding groove 81, the sliding block 71 is assembled in place.

[0095] See also Figure 12-15 As shown, to facilitate the extension of the slide plate 711 from the extension opening 812, a bottom extension portion 814 extending downward and inward is provided at the bottom of the chute 811. The sidewalls of the chute 811 extend inward to form sidewall extension portions 815, which are connected to the bottom extension portion 814. The sidewall extension portion 815 has a sidewall lower end surface 8151 extending downward and outward, the upper end of which is connected to the lower end surface of the bottom extension portion. The provision of the bottom extension portion 814 and the sidewall extension portion 815 forms an inwardly protruding structure, which facilitates the fit between the slide plate 711 and the bottom extension portion 814. Furthermore, the inclined surface of the bottom extension portion 814 allows the slide plate 711 to move outward while moving upward. Therefore, the provision of the bottom extension portion 814 facilitates the assembly of the slide plate 711, reduces assembly difficulty, and improves assembly efficiency.

[0096] See also Figure 6 、 Figure 11 ,as well as Figure 13As shown, the assembly of the sliding block 71 and the sliding groove 81 realizes the positioning of the support plate 8 fixed to the cover plate 7, as well as the limitation in the left and right directions and the downward direction. In order to further increase the fixing firmness between the support plate 8 and the cover plate 7, it is convenient to transmit the force applied by the driving structure 9 to the support plate 8 to the cover plate 7, thereby realizing the opening and closing of the cover plate 7. A limiting opening 82 is provided on the support plate 8, and a plurality of limiting blocks 72 are provided on the cover plate 7 at intervals and protruding outwards. The limiting blocks 72 are located in the limiting opening 82. Specifically, two limiting blocks 72 form a group and are located in one limiting opening 82. The provision of the limiting blocks 72 and the limiting opening 82 facilitates the fixing of the support plate 8 to the cover plate 7, mainly limiting the freedom of movement in the up and down directions, and facilitates the fixing firmness between the support plate 8 and the cover plate 7. The provision of two limiting blocks 72 at intervals and located in one limiting opening 82 facilitates the strengthening of the fit. Preferably, the limit block 72 is square and gradually approaches the opposite side in the outward direction, that is, the limit block 72 is in the shape of a square platform, which is conducive to the convenience of installation of the limit block 72 and the limit opening 82 and the firmness of fixation. After the sliding block 71 is installed in the sliding groove 81, the limit block 72 and the limit opening 82 are matched.

[0097] See also Figure 9 and Figure 13 As shown, an inwardly extending retaining edge 851 is provided at the upper end of the fixing portion 85. The retaining edge 851 is located at the upper end of the cover plate 7; it is used to limit the downward freedom between the support plate 8 and the cover plate 7, increasing the force stability of the support plate 8 when pulling the cover plate 7 downward. It is also beneficial to be able to apply a certain downward pulling force to the support plate 8 through the driving structure 9 after the cover plate 7 and the inner liner 30 are sealed, which is beneficial to ensure the sealing between the cover plate 7 and the inner liner 30. Preferably, a downward folded edge 852 is provided on the inner side of the retaining edge 851, and a receiving groove 73 that matches the folded edge 852 is formed on the cover plate 7. The folded edge 852 is located within the receiving groove 73; this is beneficial to further improve the ability and stability of the support plate 8 to apply downward force to the cover plate 7.

[0098] See also Figure 13 and Figure 24As shown, in order to ensure the movement accuracy of the front end of the cover 7 when it is opened, a first limiting post 841 is provided on the outer side of the front extension 84. A limiting groove 106 is also provided at the front end of the box body 10 to match the limiting post 841. During the opening and closing process of the cover 7, the first limiting post 841 moves up and down in the limiting groove 106. The limiting groove 106 comprises a vertical outer groove bottom 1061, a vertical front groove plate 1062, a horizontal upper groove plate 1063, and a curved rear groove plate 1064. The outer groove bottom 1061 is provided with an inwardly facing front groove plate 1062, an upper groove plate 1063, and a rear groove plate 1064. The outer groove bottom 1061, the front groove plate 1062, the upper groove plate 1063, and the rear groove plate 1064 surround and form the limiting groove 106. The limiting post 841 is confined within the space of the limiting groove 106. By setting the limiting column 841, firstly, it plays a limiting role, so that the movable distance of the front extension part 84 in the outward and inward directions between the side plate of the box body 10 and the front limiting plate 105 becomes smaller, which is beneficial to reduce the shaking of the front extension part 84 in the inward and outward directions; secondly, the limiting column 841 is limited in the space of the limiting groove 106, so that when the driving structure 9 pushes the support plate 8 to move up and down, the limiting column 841 moves up and down along the rear groove plate 1064 in the limiting groove 106, thereby realizing the movement limitation of the front end of the support plate 8 and realizing the opening and closing of the cover plate 7.

[0099] The rear groove plate 1064 has an arc section 10641 that bends downward along the rear end of the upper groove plate 1063, an inclined section 10642 that tilts downward and forward along the arc section 10641, and a waist section 10643 that extends downward along the inclined section 10642; after the cover plate 7 and the liner 30 are sealed and fastened, the limiting column 841 is located in the waist section 10643, so that the limiting column 841 is limited between the waist section 10643 and the front groove plate 1062, wherein the diameter of the limiting column 841 matches the distance between the waist section 10643 and the front groove plate 1062, or in other words, the limiting column The diameter of 841 is slightly smaller than the distance between the waist section 10643 and the front groove plate 1062. In this way, after the cover plate 7 is sealed and fastened to the inner liner 30, the cover plate 7 cannot shake in the front and rear directions, thereby ensuring the stability of the seal between the cover plate 7 and the inner liner 30; during the opening process of the cover plate 7, the limiting column 841 moves between the inclined section 10642 and the front groove plate 1062, and the movable distance of the limiting column 841 in the front and rear directions is relatively large; after the upper cover 7 is opened, the upper end of the cover plate 7 moves upward and backward in an arc shape, and the limiting column 841 is located at the arc section 10641. The rear groove plate 1064 also has a flared section 10644 that is inclined downward and backward along the lower end of the waist section 10643, which is conducive to the installation of the limiting column 841 into the limiting groove 106; the rear groove plate 1064 also has a limiting section 10645 that extends horizontally backward along the lower end of the flared section 10644, which is conducive to increasing the structural strength of the rear groove plate 1064, and facilitating the limiting column 841 to slide forward along the limiting section 10645 into the limiting groove 106.

[0100] See also Figure 11 、 Figure 20 ,as well as Figure 21 As shown, a rear extension portion 86 extending rearward is provided at the upper end of the support body 80, and a rear limit plate 107 is provided at the rear end of the dishwasher housing 10. The rear extension portion 86 is located between the side panels of the housing 10 and the rear limit plate 107. This allows the rear extension portion 86 to be positioned only between the side panels of the housing 10 and the rear limit plate 107 in the inward and outward directions, acting as an inward and outward limit for the rear end of the support plate 8, thereby preventing the support plate 8 from shaking in the inward and outward directions during the up and down movement. An upward U-shaped groove 1071 is provided on the rear limit plate 107. A stopper 1072 surrounded by the U-shaped groove 1071 is bent inward and then stopped above the rear extension portion 86. This ensures that when the drive structure 9 pushes the support plate 8 upward, the rear end of the support plate 8 is limited to continue moving upward, and only the front end of the support plate 8 can rotate upward to open.

[0101] A second limiting column 861 protruding outward is provided on the rear extension portion 86. The second limiting column 861 plays a limiting role, so that the movable distance of the rear extension portion 86 in the outward and inward directions between the side panel of the box body 10 and the rear limiting plate 107 becomes smaller, which is beneficial to reducing the shaking of the rear extension portion 85 in the inward and outward directions; wherein, the cross-section of the second limiting column 861 is runway-shaped, which is beneficial to improve the structural strength of the second limiting column 861 and improve the stability of the limitation.

[0102] See also Figure 2 and Figure 3 As shown, an L-shaped track support plate 109 is provided at the lower end of the dishwasher housing 10. A track for pulling out the drawer 20 is located between the drawer 10 and the track support plate 109. A fixing opening 1091 is provided on the track support plate 109 to mate with the drive body 91, which is secured to the fixing opening 1091. While the track support plate 109 supports the track, it also secures the drive mechanism 9. The fixing opening 1091 is a vertical opening. A plurality of outwardly extending fixing hooks 1092 are provided on the lower edge of the track support plate 109. The drive body 91 is provided with fixing posts 911 that mate with the fixing hooks 1092.

[0103] See also Figures 25-30As shown, when the dishwasher drawer 20 is pulled out, the pipes and wires connected to the inner tank also need to follow the movement. In order to ensure the neatness of the tube bundle and avoid accumulation and bending, a tube bundle guide structure is provided at the rear of the drawer 20. The tube bundle guide structure is arranged between the back plate 101 of the cabinet 10 and the drawer 20. The tube bundle guide structure includes: a base 121 and a guide rod 122. The guide rod 122 is rotatably connected to the base 121. The guide rod 122 is formed with a tube bundle accommodating portion 123 for accommodating the tube bundle. The base 121 is fixed to the inner surface of the back plate 101. The tube bundle 100 is connected to the back plate of the drawer 20. The tube bundle 100 passes through the tube bundle accommodating portion 123 and is connected to other water channel structures of the dishwasher. The guide rod 122 rotates around the rotation axis under the traction of the tube bundle 100. It can guide the wire harness, tube bundle, etc. connected to the drawer 20. When the drawer 20 is pulled out, the tube bundle 100 moves outward as the drawer 20 is stretched. The guide rod 122 rotates around the rotation axis under the traction of the tube bundle 100. Its motion trajectory has a motion component in the motion direction of the inner tank. It can follow the drawer 20 or the tube bundle 100 to move a distance in front of the back plate of the box body 1010. When the drawer 20 is pushed into the box body 1010, the tube bundle 100 is squeezed by the drawer 20 and moves backward. The tube bundle 100 drives the guide rod 122 to rotate around the rotation axis. The rod 122 rotates in the opposite direction about the rotation axis. Simultaneously, the tube bundle 100 moves rearward along its length within the tube bundle receptacle 123. The tube bundle receptacle 123 guides the tube bundle 100 during its backward movement, allowing the tube bundle 100 to follow a specific trajectory and ultimately become parallel to the rear panel 101 of the cabinet 10. The tube bundle 100 remains within the tube bundle receptacle 123, preventing the drawer 20 from squeezing the water pipes when the drawer 20 is pushed back, causing them to bend or kink, which could ultimately lead to technical problems such as blocked water passages. It should be noted that the "front" and "rear" referred to in this embodiment refer to the dishwasher in its normal state, with the side facing the user being the front and the side facing away from the user being the rear.

[0104] In order to facilitate the insertion of the tube bundle 100 into the tube bundle accommodating portion and facilitate disassembly, the tube bundle accommodating portion 123 is preferably a U-shaped structure with an opening. The tube bundle 100 can be inserted into its inner cavity through the opening of the U-shaped structure, thereby limiting the position of the wire harness. The tube bundle accommodating portion 123 and the guide rod 122 can be a separate structure. The tube bundle accommodating portion 123 is fixed to the outer surface of the wire rod 122. To facilitate production and increase the stability of the connection between the two, in this embodiment, the guide rod 122 and the tube bundle accommodating portion 123 are preferably formed in one piece. Specifically, the second end of the guide rod 122 is formed in one piece with the tube bundle accommodating portion 123. The tube bundle accommodating portion 123 is bent multiple times to form a U-shaped groove structure.

[0105] See also Figure 28As shown, the base 121 includes a bottom edge 1211 and a side edge 1212 formed on the bottom edge 1211. The side edge 1212 extends forward from the front surface of the bottom edge 1211 and is formed with a shaft insertion portion 1213. The shaft insertion portion 1213 defines an axis hole 1214. The first end of the guide rod 122 is inserted into the axis hole 1214 and can rotate around the axis hole under the traction of the tube bundle 100. The rear surface of the bottom edge 1211 is fixed to the back plate of the box body 1010.

[0106] See also Figure 30 As shown, the guide rod 122 includes a first connecting arm 1221, a second connecting arm 1222, and a third connecting arm 1223 connected in sequence. The three connecting arms are each a straight rod structure. The first connecting arm 1221 is the first end of the guide rod and is inserted into the shaft hole. When the inner container is pulled out, the first connecting arm 1221 rotates in the shaft hole, forming a certain angle with the back plate of the box body 10. When the inner container is pushed back into the box body 10, the first connecting arm 1221 rotates in the opposite direction until all three connecting arms of the guide rod 122 are close to the back plate of the box body 10.

[0107] The third connecting arm 1223 is connected to the tube bundle accommodating portion 123 .

[0108] Since the height of the inner container is fixed, the length of the guide rod 122 is limited by the height of the inner container. In order to simultaneously meet the requirements of the guide rod 122 being able to rotate around the axis and extending the guide rod when the drawer 20 is pulled out, the guide rod 122 can have a sufficiently long displacement component in the direction of the drawer 20 being pulled out, such as Figure 7 As shown, in this embodiment, the included angle between the first connecting arm 1221 and the second connecting arm 1222 is an obtuse angle, and the included angle between the second connecting arm 1222 and the third connecting arm 1223 is an obtuse angle, which can extend the displacement component of the guide rod in the direction of withdrawing the drawer 20. The guide rod 122 of this embodiment is not limited to being composed of three or more sections connected in sequence, but can also be designed as two sections, including a section inserted into the shaft hole and a section outside the shaft hole. The section inserted into the shaft hole is designed as a straight rod, and the section outside the shaft hole is designed as an arc-shaped structure, which can also serve to extend the displacement component of the guide rod in the direction of withdrawing the drawer 20.

[0109] In order to provide enough rotation space for the guide rod to rotate around the axis, the base 121 can be fixed on the back plate of the box body 10. Figure 29 As shown, the angle between the axis of the shaft hole 1214 and the bottom edge 1211 is an acute angle with the opening facing upward. The insertion opening of the shaft hole 1214 faces upward to facilitate the insertion of the guide rod 122.

[0110] When the guide rod 122 rotates in the shaft hole 1214, a certain tension is generated on it. In order to improve the supporting strength of the side 1212, it also includes ribs 1215. The two ends of the ribs 1215 are respectively connected to the shaft plug-in part 1213 and the bottom edge 1211. The number of ribs 1215 can be set according to actual needs.

[0111] See also Figure 28 As shown, the shaft plug-in portion 1213 includes a funnel-shaped insertion port and a straight cylindrical structure. The insertion port and the straight cylindrical structure are coaxially arranged. The guide rod 122 is inserted into the straight cylindrical structure from the insertion port. By setting the funnel-shaped insertion port, the diameter is larger at the upper part and smaller at the lower part, which facilitates the alignment and insertion of the guide rod 122. By setting a straight cylindrical structure, the insertion depth of the guide rod 122 can be extended and the stability can be improved.

[0112] The tube bundle guide structure in this embodiment is not limited to use in drawer-type dishwashers, but can also be set at the rear of other pull-out structures. It can guide the wire bundle, tube bundle, etc. connected to the push-pull structure. When the push-pull structure is pulled outward, the tube bundle is stretched along with the push-pull structure, and the guide rod rotates around the rotation axis under the traction of the tube bundle, so that the tube bundle is guided by the tube bundle guide structure while being stretched by the push-pull structure, and moves outward according to a certain trajectory. When the push-pull structure is pushed into the inner tank, the wire rod is rotated in the opposite direction around the rotation axis, and finally fits into or approaches the back plate of the box body 10. The tube bundle always remains in the tube bundle accommodating portion, so that the tube bundle returns along the pulled-out trajectory, preventing the tube from being squeezed or tangled when the push-pull structure is pushed back.

[0113] See also Figure 1 、 Figures 31-36As shown, a handle display panel 1 is also provided at the front end of the drawer 20. The handle display panel 1 is arranged at the upper end of the door panel assembly 2. The handle display panel 1 and the door panel assembly 2 constitute the front face of the dishwasher. A first limiting structure and a second limiting structure for sliding assembly are provided between the handle display panel 1 and the drawer 20. The first limiting structure comprises a limiting guide groove 111 provided on the handle display panel 1 and a limiting guide plate 201 provided on the drawer 20. The limiting guide plate 201 matches the limiting guide groove 111 and is located within the limiting guide groove 111. The provision of the limiting guide plate 201 and the limiting guide groove 111 facilitates the sliding assembly of the handle display panel 1. The provision of the sliding assembly increases the contact area between the limiting guide plate 201 and the limiting guide groove 111, which helps to increase the firmness after fixation. The structure also serves as a positioning function during assembly and at least limits the front-to-back position of the handle display panel 1. The second limiting structure is a limiting claw 112 provided on the handle display panel 1 and a second limiting groove 202 provided on the drawer 20. The second limiting groove 202 matches the limiting claw 112. The limiting claw 112 is clamped in the second limiting groove 202, which can at least limit the movement trend of the handle display panel 1 in the upward, downward and right directions. Therefore, the first limiting structure and the second limiting structure cooperate to fix the handle display panel 1.

[0114] A rearward-projecting L-shaped guide plate is provided on the handle display panel 1, forming a downward-opening limit guide slot 111 between the guide plate and the handle display panel 1. An upward-extending limit guide plate 201 is provided at the top front end of the drawer 20. Its length is the same as the left-right dimension of the drawer 20. The provision of a full-length limit guide plate 201 enhances its structural strength; the first limit structure restricts the handle display panel 1's forward and backward movement, as well as its downward freedom.

[0115] In this embodiment, the drawer 20 is provided with an installation avoidance groove 203 for installing the handle display panel 1. The installation avoidance groove 203 is connected to the second limiting groove 202. When installing the handle display panel 1, the limiting claw 112 is first extended into the installation avoidance groove 203. Then, the handle display panel 1 is lifted upward to control the limiting guide groove 111 to insert the limiting guide plate 201 from above. Then, the handle display panel 1 is pushed along the direction of the limiting guide plate 201 and the limiting guide groove 111, so that the limiting claw 112 slides from the installation avoidance groove 203 into the second limiting groove 202. The provision of the installation avoidance groove 203 ensures the coordinated assembly of the first limiting structure and the second limiting structure.

[0116] A third limiting structure is provided between the handle display panel 1 and the dishwasher drawer 20. The third limiting structure comprises a third engaging groove 119 provided on the handle display panel 1 and a third engaging plate 204 provided on the dishwasher drawer 20. The third engaging plate 204 is engaged and fixed in the third engaging groove 119. A third stop plate 209 is provided at one end of the third engaging plate 204 to limit the third engaging groove 119 from being installed in place. The third engaging plate 204 is vertically arranged in the left-right direction, while the third stop plate 209 is vertically arranged in the front-back direction. When the handle display panel 1 is installed, the control panel is pushed rightward to slide and assemble, causing the third engaging groove 119 to move rightward. After the third engaging groove 119 contacts the third stop plate 209, the control panel is installed in place. The engaging and fixing can be achieved by adjusting the width of the third engaging groove 119 and the thickness of the third engaging plate 204. The third engaging plate 204 and the third engaging slot 119 facilitate securing the handle display panel 1. The opening of the third engaging slot 119 is arranged opposite the opening of the limiting guide slot 111, increasing stability and firmness after securing. The panel body 1 is provided with a rearward-extending, upward-opening third engaging slot 119. Preferably, the handle display panel 1 is provided with two third positioning slots, one on the left and one on the right.

[0117] The following describes the installation method of the handle display panel 1 in this embodiment, which includes the following steps:

[0118] Place the handle display panel 1 close to the drawer 20 of the dishwasher, and allow the limiting claw 112 to extend into the installation avoidance groove 203;

[0119] Move the handle display panel 1 upwards so that the limiting guide plate 201 fits into the limiting guide groove 111;

[0120] The handle display panel 1 is pushed to move rightward, so that the handle display panel 1 slides along the direction of the limiting guide groove 111 and the limiting guide plate 201 , and the limiting claw 112 slides into the second limiting groove 202 .

[0121] Specifically, at the same time, the third engaging plate 204 is engaged and fixed in the third engaging slot 119 , and the third stopping plate 209 stops the third engaging slot 119 from continuing to move rightward, thereby installing the handle display panel 1 in place.

[0122] See also Figure 36As shown, the panel body 11 is provided with a display control board box 14 for accommodating a display control board. The panel body 11 is provided with an assembly cavity. The control panel assembly 1 also includes an insert plate 15 for compressing and securing the display control board box 14. The insert plate 15 slides into the assembly cavity. By providing the insert plate 15, the insert plate 15 slides into the assembly cavity. When the insert plate 15 slides into place, it is compressed and secured between the display control board box 14 and the wall of the assembly cavity, thereby compressing and securing the display control board box. This improves the assembly efficiency of the control panel assembly and facilitates the removal of the display control board box 14. It also increases the contact area between the display control board box 14, the insert plate 15, and the assembly cavity, thereby improving the stability and firmness of the fixation. The upper end surface of the panel body 11 is a forward and downwardly inclined surface, which facilitates the forward flow of water dripping onto the upper end surface of the panel body 11 and the downward flow of water from the front end surface of the panel body 1, preventing the water from flowing backward into the assembly gap between the panel body and the drawer 20.

[0123] In this embodiment, the display control element on the display control board extends from the front end surface of the display control board box 14, and a mounting portion for matching the display control board and a display screen 116 arranged in front of the mounting portion are provided on the front wall of the assembly cavity.

[0124] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other manner. Any person skilled in the art may utilize the above-disclosed technical content to modify or modify the present invention into equivalent embodiments. However, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention remain within the scope of protection of the present invention.
