The clamping rib 11211 is pushed and assembled upward from below the clamping groove 1131. Preferably, a plurality of vertically spaced and parallel clamping ribs 11211 are provided on the clamping portion 1121.

[0082] In this embodiment, a protruding positioning block 1133 is provided at the upper end of the clamping groove 1131 on the panel body 11. A positioning groove 11213 matching the positioning block 1133 is provided on the clamping portion 1121, and the positioning block 1133 is located in the positioning groove 11213. Preferably, a clamping protrusion 11214 extending upward is provided at the positioning groove 11213. A second clamping groove matching the clamping protrusion 11214 is provided on the positioning block 1133, and the clamping protrusion 11214 is located in the second clamping groove. By providing the clamping protrusion 11214 and the second clamping groove, it is used for the assembly and fixation of the upper end of the clamping portion 1121 and the panel body 11 to ensure the firmness of the assembly after fixation. Preferably, the clamping rib 11211 extends toward the positioning groove 11213 to form the clamping protrusion 11214.

[0083] In this embodiment, a first card slot 1132 is provided in the notch 113 of the panel body 11. A first snap 11212 that matches the first card slot 1132 is provided on the card mounting portion 1121. After the limiting claw 112 is assembled, the first snap 11212 is snap-fitted and fixed in the first card slot 11212. Preferably, two first card slots 1132 are provided side by side and at intervals on the notch 113, and two first snaps 11212 are provided side by side and at intervals on the lower part of the front end face of the card mounting portion 1121. By providing the first card slot 1132 and the first snap 11212, the limiting claw 112 is firmly snap-fitted and fixed on the panel body 11.

[0084] In this embodiment, a guide plate 1134 for positioning the engaging rib 11211 is provided at the lower end of the engaging slot 1131 on the panel body 11 and extends downward. When the card mounting portion 1121 is installed, first, the limiting claw 112 is brought close to the notch 113 of the panel body 11, and the engaging rib 11211 is made to correspond to the lower part of the engaging slot 1131. Then, the limiting claw 112 is pushed upward. During the upward movement, the guide plate 1134 plays a role in limiting and guiding the engaging rib 11211. When the card mounting portion 1121 is installed in place, the first snap 11212 is snap-fitted and fixed in the first card slot 11212. The sliding assembly direction of the limiting claw 112, the sliding assembly direction of the panel body 11, and the pulling and opening / closing direction of the drawer 20 are perpendicular to each other.

[0090] Specifically, at the same time, the third engaging plate 204 is engaged and fixed in the third engaging groove 119, and the third stop plate 205 stops the third engaging groove 119 from moving rightward any further, and the control panel 1 is installed in place.

[0091] See Figure 8 、 Figures 14 - 19 for the description of the structure and assembly of the display control board box 14. A display control board box 14 for accommodating the display control board is provided on the panel body 11. An assembly cavity is provided on the panel body 11. The control panel assembly 1 further includes an insertion plate 15 for pressing and fixing the display control board box 14. Among them, the insertion plate 15 slides and inserts into the assembly cavity. By providing the insertion plate 15, the insertion plate 15 slides and inserts into the assembly cavity, and when the insertion plate 15 slides in place, the insertion plate 15 is pressed and fixed between the display control board box 14 and the wall surface of the assembly cavity, that is, the display control board box is also pressed and fixed; this is beneficial to improving the assembly efficiency of the control panel assembly, and also facilitates the disassembly of the display control board box 14, and increases the contact area between the display control board box 14, the insertion plate 15, and the assembly cavity, which is beneficial to improving the stability and firmness of the fixation. The upper end surface of the panel body 11 is an inclined surface that slopes forward and downward, which is beneficial to the water dripping onto the upper end surface of the panel body 11 to flow forward, and the front end surface of the panel body 1 flows downward, avoiding the water flow from flowing backward into the assembly gap between the panel body and the drawer 20.

[0092] In this embodiment, the assembly cavity is a cavity with an opening downward. Guide limit plates 115 that match the display control board box 14 are provided on the left and right sides of the assembly cavity; an extension limit plate 1411 that extends left and right is provided on the front end surface of the display control board box 14, and the extension limit plate 1411 matches the guide limit plates 115; the width of the display control board box 14 matches the distance between the two guide limit plates 115, that is, the width of the display control board box 14 is equal to or slightly less than the distance between the two guide limit plates 115; in this way, the top surface of the display control board box 14 abuts against the top surface of the assembly cavity, and the display control board box 14 is limited in the left and right directions between the two guide limit plates 115.

[0093] In this embodiment, the display control element on the display control board extends from the front end face 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 arranged on the front wall of the assembly cavity. In order to position the display control board box 14 during installation and ensure stability after fixation, a first positioning structure is arranged between the front end face of the display control board box 14 and the front wall of the assembly cavity; specifically, the first positioning structure is a positioning cylinder 1412 arranged on the front end face of the display control board box 14 and convex forward, and a positioning hole of the mounting portion arranged on the front wall of the assembly cavity.

[0094] In this embodiment, a guide rail and guide groove structure for positioning and guiding the plug board 15 is provided between the display control board box 14 and the plug board 15. Specifically, a guide rail 1421 for the sliding assembly direction of the plug board 15, that is, a guide rail 1421 in the up and down direction is provided on the rear end face of the display control board box 14, and a concave guide groove 151 matching the guide 1421 is provided on the front end face of the plug board 15; the plug board 15 slides along the guide rail and guide groove structure and is inserted between the display control board box 15 and the rear wall of the assembly cavity. After the plug board 15 slides into place, the plug board 15 is clamped between the display control board box 14 and the wall of the assembly cavity in the front and rear directions.

[0095] In this embodiment, a fifth clip 1422 protruding toward the plug board 15 is provided on the display control board box 14, and a fifth claw 152 matching the fifth clip 1422 is provided on the plug board 15. After the plug board 15 slides into place, the fifth claw 152 is engaged and fixed on the fifth clip 1422. The fifth claw 152 is arranged at the lower part of the front end surface of the plug board 15, and the fifth claw 152 extends downward to form a handle 153 extending out of the plug board, and the handle 153 is used to manually release the locking relationship between the fifth claw 152 and the fifth clip 1422. That is, when removing the plug board 15, the handle 153 is bent backward, and the plug board 15 is pulled downward, so that the fifth claw 152 is separated from the fifth clip 1422. Since the fifth buckle 1422 protrudes from the rear end surface of the display control board box 14, a buckle avoidance slot 154 for avoiding the fifth buckle 1422 is provided on the plug board 15, and the buckle avoidance slot 154 extends along the assembly direction of the plug board 15, or in other words, the buckle avoidance slot 154 is arranged in the up-down direction. During the sliding assembly process of the display control board box 14, the fifth buckle 1422 slides in the buckle avoidance slot 154, so the buckle avoidance slot 154 and the fifth buckle 1422 also play a certain guiding and limiting role. The fifth buckle 1422 is arranged in the buckle avoidance slot 154.
