[0055] With the continuous upgrading of air conditioners, their performance, comfort, appearance, etc. have been greatly improved. In the current market, round cabinets are popular among consumers. The display of round cabinets is usually located just above the air outlet. When the air conditioner is cooling, condensation water is easy to be generated at the display position. If it enters the circuit board, wiring and other positions, it will cause safety hazards.

[0056] In the prior art, the circuit board is usually vertically fixed to the rear side of the display module through a display box, and the display box is sealed by adding a sponge to prevent condensed water from entering the display box and dripping onto the circuit board, thereby affecting the normal operation of the circuit board.

[0057] However, sticking the sponge will not only reduce the assembly efficiency, but the sealing effect of the sponge will also fail over time, causing water to enter the display box and damage the internal circuit board, affecting the user experience.

[0058] Moreover, since the length of the display box is greater than that of the display module, the vertical display box will protrude downward relative to the display module in the vertical direction. This part of the display box will also affect the height of the air outlet, reduce the air output of the air conditioner, and affect the cooling or heating effect.

[0059] Based on this, Figure 1-Figure 9 As shown, the display assembly according to the embodiment of the utility model is applied to an air conditioner indoor unit, the air conditioner indoor unit includes a housing 9, a housing cavity 10 is formed in the housing 9, the display assembly is used to be arranged in the housing cavity and the display assembly includes:

[0060] Display module 1, the display module is provided with a display surface extending in a vertical direction, the display surface is used to display and / or input and / or interact with air conditioning information;

[0061] A display box 3 is arranged on the back side of the display module 1 opposite to the display surface. The display box 3 includes a display box body, and a mounting cavity is formed inside the display box body;

[0062] A circuit board 2 is arranged in the mounting cavity, and the circuit board is electrically connected to the display module;

[0063] The display box body of the display box 3 is arranged horizontally, and its side wall is connected to the back side of the display module.

[0064] Specifically, the horizontal setting is inclined at a certain angle relative to the completely vertical direction, and does not require to be completely horizontal. The display module 1 can be a liquid crystal display. The display module 1 has a display surface. The display surface of the display module 1 is a surface representing the main body of the display module 1. A mounting hole can be set on the side wall of the shell 9, and the display module 1 is embedded in the mounting hole. The display module 1 can display the air conditioner information so that the user can understand the operating status of the air conditioner. It can also have a touch function so that the user can interact with the air conditioner through the display module 1.

[0065] The circuit board 2 can be a PCB board. The circuit board 2 can be electrically connected to the display module 1 through the electrical connection line 7 to provide current and signals for the display module 1. The circuit board 2 is placed in the installation cavity of the display box 3. The board body of the circuit board 2 can be parallel to the display surface of the display box 3. The circuit board 2 can be horizontally arranged together with the display box 3.

[0066] The display box 3 can be a rectangular box body, and the circuit board 2 is placed in the display box 3. The circuit board 2 is installed and protected by the display box 3. The display box 3 can be composed of a box body 31 and a box cover 32 that are buckled together. Compared with the prior art, the circuit board 2 is placed flat in the display box 3, the display box 3 is vertically set, and the box body 31 and the box cover 32 are buckled together in the horizontal direction. The horizontally set display box 3 in the present application can avoid the fitting gap generated when the box body 31 and the box cover 32 are buckled together to extend in the vertical direction, and the condensed water flowing downward under the action of gravity flows along the fitting gap all the time, increasing the risk of wind inlet. The inclined display box 3 can make the fitting gap also be set horizontally, so that the flow direction of the condensed water has a slight angle with the extension direction of the fitting gap, so that the condensed water passes through the fitting gap when flowing downward, instead of flowing along the fitting gap all the time, so that the display box 1 has a certain waterproof effect.

[0067] In the present application, the circuit board is stored and protected by a display box. Since the bottom of the display box 3 is arranged horizontally in the direction away from the display module 1, the display box is composed of a box body and a box cover that are buckled in the up and down directions, so that the fitting gap after the box body and the box cover are buckled is set on the side wall of the display box in the horizontal direction, so that the fitting gap generated after the box body 31 and the box cover 32 are buckled is located on the side wall of the display box 3. They can be arranged horizontally together, and since condensed water will flow from the top of the display box 3 to the bottom of the display box 3 under the action of gravity, after the fitting gap is set on the side wall of the display box 3, compared with the horizontal buckling in the prior art, the condensed water flows along the vertical fitting gap. In the scheme proposed in the present application, the condensed water can directly flow through the fitting gap during the flow, which can greatly reduce the contact time between the condensed water and the fitting gap, thereby playing a certain waterproof role.

[0068] Moreover, the display surface of the display box 3 in the present application is arranged horizontally in the direction away from the display module 1, that is, the display box 3 is arranged horizontally relative to the display module 1 and is no longer parallel to the display module 1. The display box 3 and the display module 1 can also be specifically arranged in an "L" shape. The display box 3 extends in the horizontal direction and is perpendicular to the display module 1. This can avoid the display box 3 occupying too much longitudinal space and the display box 3 affecting the height of the air outlet 11 of the air-conditioning indoor unit. This can make the air-conditioning indoor unit have better air outlet efficiency and the air conditioner have better cooling or heating effects.

[0069] The present application achieves a certain waterproof effect by setting a matching gap on the side wall of the display box 3 along the horizontal direction, which can avoid adding sponges for waterproofing, avoid adding assembly steps and reducing assembly efficiency by installing sponges, and can also avoid water leakage due to aging of the sponge and damage to the circuit board 2.

[0070] According to the display assembly of the embodiment of the utility model, the circuit board is stored and protected by the display box, and the bottom of the display box 3 is arranged horizontally in the direction away from the display module. The inclined display box 3 will not take up too much vertical space, affecting the height of the air outlet of the indoor unit of the air conditioner, so that the air conditioner can have a better air outlet efficiency, and the display box 3 can be composed of a box body 31 and a box cover 32 that are buckled together in the up and down directions. The horizontally arranged display box 3 can make the fitting gap after the box body 31 and the box cover 32 are buckled together also be designed to be inclined, so that when condensation water is generated on the display box 3, the condensation water flows from the top to the bottom of the display box under the action of gravity. The condensation water will not flow along the fitting gap and increase the risk of water entering the display box, but will directly pass through the gap from top to bottom, so that the display box has a certain waterproof function, and there is no need to set a sponge for waterproofing, which can improve the assembly efficiency and will not leak due to aging of the sponge, resulting in damage to the circuit board.

[0071] In some embodiments, the display box body of the display box 3 has a top wall opposite to the board surface of the circuit board 2, and an angle α is formed between the top wall and the display surface of the display module 1, and α satisfies: 10°<α≤100°;

[0072] Preferably, the display box body is arranged perpendicular to the display surface of the display module 1, that is, α=90°, and the circuit board is arranged transversely in the installation cavity of the display box body.

[0073] Specifically, α can be 11°, and the display surface of the display box 2 is slightly inclined in the direction away from the display module 1, but compared with α being 0°, compared with the vertical setting of the display surface of the display box 2, the slightly inclined display box 2 can occupy less vertical space, reducing the impact on the height of the air outlet of the indoor unit of the air conditioner. When α can be 90°, the display surface of the circuit board 2 and the display module 1 meet a vertical relationship, the display module 1 is arranged in the vertical direction, the circuit board 2 is arranged in the horizontal direction, and the display box 3 is also arranged in the horizontal direction. The display box 3 and the display module 1 are in an "L" shape, and the space in the vertical direction occupied by the entire display assembly is the space in the vertical direction occupied by the display module 1, which can maximize the reduction of the impact of the display box 2 on the height of the air outlet of the indoor unit of the air conditioner. α can be 100°, and the end of the display box 2 facing away from the display module 1 is tilted upward, which can be to move the display module 1 downward by a certain distance, but compared with the vertical setting of the display box 2, it can also reduce the overall occupation of the height space by the display assembly, or the cabinet housing can be made into a bulge upward to accommodate the tilted display box 2.

[0074] In some embodiments, the display box body of the display box 3 includes a box body 31 and a box cover 32, and the box body 31 and the box cover 32 cooperate with each other up and down to form an installation cavity;

[0075] The box body 31 is arranged above the box cover 32, and the upper and lower matching positions of the box body 31 and the box cover 32 are lower than the setting position of the circuit board in the installation cavity.

[0076] Specifically, the box body 31 can be a rectangular body with an opening, and the box cover 32 can be a rectangular cover adapted to the box body 31. After the box body 31 is fixed, the opening of the box body 31 can be set in a certain direction, and then the circuit board 2 and the corresponding components can be set in the box body 31, and then the box cover 32 can be snapped with the box body 31 from below, and the box body 31 and the box cover 32 can be connected and fixed by bolts. Not only can the fitting gap be configured on the side wall of the display box 3, but it can also facilitate disassembly and assembly, which helps to improve assembly efficiency.

[0077] Moreover, the circuit board 2 is arranged in the box body 31. When water enters the display box 3, condensed water will drip into the box cover 32 under the action of gravity. Compared with the case where the display box 3 and the circuit board 2 are arranged vertically, condensed water can be prevented from dripping directly onto the circuit board 2, thereby preventing the circuit board 2 from being damaged by water.

[0078] In some embodiments, the box body 31 and the box cover 32 are arranged opposite to each other up and down, and the box body 31 is above the box cover 32, and the assembly direction of the box body 31 and the box cover 32 is a vertical direction.

[0079] In some embodiments, one of the box body 31 and the box cover 32 is formed with a male stopper 41 , and the other is formed with a female stopper 42 ; the male stopper 41 and the female stopper 42 form a sealing fit.

[0080] Specifically, the stop structure can be a single stop, which is composed of a male stop 41 and a female stop 42. From the appearance, it is a pair of concave-convex structures. The pair of concave-convex structures are designed on the box body 31 and the box cover 32 respectively. The protruding part along the inner edge of the side wall is called the male stop 41, and the male stop 41 is arranged on the box cover 32. The concave part cut off along the inner edge of the side wall is called the female stop 42. The female stop 42 is arranged on the box body 31. The stop structure can not only play the role of installation limit and anti-static, but also because the female stop 42 has a notch on the inner side and a protrusion on the outer side, and the male stop 41 has a notch on the outer side and a protrusion on the inner side, when condensation water flows through the stop structure, the female stop 42 and the male stop 41 can also play a waterproof role to prevent condensation water from flowing into the display box 3 from the fitting gap.

[0081] In some embodiments, a front seat body 15 extending vertically downward is formed on one side of the box body 31 close to the back of the display module, and the front seat body 15 is used to cooperate with the back of the display module 1;

[0082] Preferably, the box body 31 and the front seat body 15 are formed integrally.

[0083] Specifically, the box body 31 is connected to the display module through the side wall extending downward, which can be specifically connected by snap connection, screw connection, etc. The box body 31 can be an "L"-shaped structure as a whole. By lengthening the side wall used for the display module 1, the connection strength between the box body 31 and the display module 1 can be improved. Preferably, the side wall can be integrally formed with the main part of the entire box body 31 to ensure the overall strength of the side wall and the box body 31.

[0084] In some embodiments, a matching gap is formed at the matching position of the box body 31 and the box cover 32;

[0085] The outer wall of the box body 31 is provided with a water guide cover 5 , and at least a part of the water guide cover 5 is provided at the matching gap between the box body 31 and the box cover 32 .

[0086] Specifically, the water guide hood 5 is arranged on the outer wall of the box body 31, and the water guide hood 5 extends from the box body 31 to the box cover 32, so that a part of the water guide hood 5 can be covered at the fitting gap. When condensed water flows along the outer wall of the box body 31, it will gather downward under gravity. The water guide hood 5 is arranged at the fitting gap, which can make the gathered condensed water flow along the water guide hood 5, cross the fitting gap, and then drip downward, which can greatly reduce the condensed water flowing into the fitting gap, reduce the contact between the fitting gap and the condensed water, and reduce the probability of condensed water entering the display box 3 from the fitting gap, further improve the waterproof effect of the display box 3, and avoid water damage to the circuit board 2.

[0087] In some embodiments, an elastic seal 6 is further provided on the end surface of the water guide cover 5 facing away from the box body 31, and the elastic seal 6 elastically presses against the outer wall of the box cover 32, and the water guide cover 5, the elastic seal 6, the outer wall of the box body 31 and the outer wall of the box cover 32 form a sealed cavity;

[0088] The matching gap between the box body 31 and the box cover 32 is located in the sealed cavity.

[0089] Specifically, a circle of elastic sealing member 6 can be further provided under the water guide cover 5. The elastic sealing member 6 can be made of rubber material. The elastic sealing member 6 has a certain elasticity. On the one hand, it does not affect the snap-fit ​​installation of the box cover 32 and the box body 31. On the other hand, it can also be closely attached to the inner wall of the box cover 32, so that a sealed cavity is formed between the elastic sealing member 6, the water guide cover and the side wall of the display box 3. The sealing cavity isolates the fitting gap and condensed water, thereby further improving the sealing and waterproof effect of the display box 3, and also preventing the airflow in the accommodating cavity 10 from forming a vortex in the water guide cover 5, thereby affecting the airflow or generating noise.

[0090] In some embodiments, a guide arc surface is provided on the inner wall of the bottom of the box cover 32, and a drainage port is provided at the lowest position of the guide arc surface.

[0091] Specifically, the guide arc surface can be an arc surface. The arc surface on the inner wall of the bottom of the box cover 32 can make the water flow in the box cover 32 converge to the lowest point of the arc surface, and then discharge the accumulated water at the bottom of the box cover 32 through the drain port. When water enters the display box 3, the accumulated water can be collected and discharged, which can prevent the display box 3 from accidentally entering with water, and the circuit board 2 from being submerged by continuous water accumulation inside, causing damage to the circuit board 2.

[0092] In some embodiments, the bottom of the box body 31 has a threading hole, one end of the electrical connection line 7 is passed through the threading hole and is arranged at the bottom of the box body 31 to be connected to the circuit board 2, and the other end is connected to the display module 1.
