[0029] The utility model will be further illustrated in combination with specific embodiments, and the embodiments are implemented on the premise of the technical scheme of the utility model, and it should be understood that these embodiments are only used for illustrating the utility model and are not used for limiting the scope of the utility model.

[0030] As Figure 1 shown, an embedded installation type display screen comprises a display module 1, a panel assembly 2 and a front control plate support 3, the display module 1 is arranged in the panel assembly 2, and the panel assembly 2 is embedded on the front control plate support 3. The display module 1 comprises a PCB board 13, a foam 14 and a diaphragm 15, and further comprises a light guide plate arranged on the inner side of the foam 14.

[0031] As Figure 2 shown, the panel assembly 2 of the embodiment is a whole structure, the panel assembly 2 is integrally injection molded or molded, and the whole is made of transparent or translucent material, so that the whole structure has better waterproof performance.

[0032] Or as Figure 3 shown, the panel assembly 2 is a split structure comprising a panel support 21 and a transparent display window 22, the panel support 21 is injection molded or molded, and the upper surface of the panel support 21 is perforated to fix the transparent display window 22, so that the panel support 21 can be made of non-transparent material.

[0033] As Figure 1 , 2, 7, the embodiment takes the panel assembly of the overall structure as an example to describe the subsequent structure. The upper surface of the panel assembly 2 is provided with a raised surface 23, which cooperates with the through hole 31 provided on the front control plate support 3, and the raised surface 23 is embedded in the through hole 31. The height of the raised surface 23 is the same as or slightly greater than the thickness of the front control plate support 3, so as to ensure that the upper surface of the raised surface 23 is flush with the outer surface of the front control plate support 3 after installation.

[0034] The outer periphery of the raised surface 23 is a panel outer ring 24 with a lower height than the raised surface 23, which is in contact with and fixed to the inner surface of the front control plate support 3. The panel outer ring 24 plays a precise limiting and positioning role, and when the raised surface 23 is embedded in the through hole 31, the panel outer ring 24 is tightly combined with the inner surface of the front control plate support 3.

[0035] In order to improve the waterproof effect and fix the panel assembly 2 to the front control plate support 3, glue is applied to the upper surface of the panel outer ring 24 and the inner surface of the front control plate support 3 for bonding.

[0036] As shown in Figures 4-6 The back of the panel assembly 2 is provided with a retaining ring 25, which cooperates with the raised surface 23 to form a cavity for accommodating the display module, and the display module 1 is fixed in the retaining ring 25 and closely arranged against the inner surface of the raised surface 23.

[0037] In order to fix the display module 1 and make it closely adhere to the raised surface 23, a first buckle is provided in the retaining ring 25, including a first movable buckle 26 provided on one side and a first fixed buckle 27 provided on the opposite side. A first recess 11 is provided on the display module 1 corresponding to the first movable buckle 26. A positioning protrusion 28 is provided in the retaining ring 25, and a positioning recess 12 is provided on the display module 1 corresponding to the positioning protrusion 28. The first recess 11 is provided to partially avoid the first movable buckle 26 during installation, leaving a space for the first movable buckle 26 to move freely, facilitating the rebound of the first movable buckle 26; the other side is positioned by the positioning protrusion 28 and the positioning recess 12, and this side can be positioned by the first recess 11 and the first movable buckle 26; after the first movable buckle 26 rebounds, it presses the PCB of the display module 1.

[0038] When installing the display module 1, the positioning protrusion 28 and the positioning recess 12 correspond to each other to ensure accurate positioning of the display module. First, one side of the display module 1 is inserted below the first fixed buckle 27, and then the other side is pressed down. The first movable buckle 26 is deformed and shrinks in the direction of the retaining ring 25. After the display module 1 enters the predetermined position, the first movable buckle 26 resets to fix the display module 1. Then, in the retaining ring 25, the back of the circuit board 13 of the display module 1 is filled with glue to form a sealing layer, further improving the waterproof effect.

[0039] The display module 1 is fixed and sealed by the first buckle and glue pouring, so that the display module 1 is tightly attached to the transparent display window of the panel assembly 2, no gap is formed, and the sensitivity and stability of touch control are improved. The glue pouring sealing further improves the stability of the connection between structures, greatly improves the waterproof effect, and prolongs the service life of the display module.

[0040] As shown in Figures 7-8 The second buckle is arranged on the front control plate support 3 and is used for fixing the panel assembly 2. The second buckle includes a second fixed buckle 32 and a second movable buckle 33. The panel assembly 2, on which the display module 1 is mounted, is fixed on the front control plate support 3 through the second fixed buckle 32 and the second movable buckle 33. Without using a screw fastening form, the panel assembly 2 can be conveniently assembled in cooperation with the structure of the convex surface 23, the upper surface of the panel assembly can be flush with the front surface of the front control plate support, and the panel assembly is not prone to displacement.

[0041] The embedded installation type display screen of the utility model includes but is not limited to washing machine, refrigerator, dishwasher, water purifier (pipeline machine, tea bar machine), smoke machine, water heater, oven, sweeper, air conditioner or other household appliances.

[0042] The above is only the preferred embodiment of the utility model, and it should be pointed out that, for ordinary skilled person in the art, several improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model.
