Description

Technical Field

[0001] This utility model relates to the field of air supply equipment technology, and more specifically, to a wall-mounted air conditioner indoor unit. Background Technology

[0002] As people's living standards improve, air conditioners have become ubiquitous in daily life, leading to increasingly higher demands on their overall performance, especially their cleaning and dust removal functions.

[0003] After prolonged use, dust accumulates on the indoor unit's filter, which can easily breed bacteria and lead to a decline in indoor air quality. Therefore, users need to clean the filter frequently, which is time-consuming and laborious.

[0004] In existing technologies, a cleaning brush can be installed and the filter screen can be moved. The filter screen is cleaned by the relative movement between the filter screen and the cleaning brush, and the dust brushed off is cleaned up, so that the dust falls into the dust collection box for collection. However, during the process of dust falling, it is very easy to stick to the inner wall of the casing between the dust collection box and the filter screen, which is used as a transition. This causes dust and dirt to accumulate inside the casing, affecting the internal environment of the indoor unit of the air conditioner and easily causing secondary pollution to the indoor unit's evaporator and cross-flow fan blades.

[0046] As people's living standards improve, air conditioners have become ubiquitous in daily life, leading to increasingly higher demands on their overall performance, especially their cleaning and dust removal functions.

[0047] After prolonged use, dust accumulates on the indoor unit's filter, which can easily breed bacteria and lead to a decline in indoor air quality. Therefore, users need to clean the filter frequently, which is time-consuming and laborious.

[0048] Based on this, such as Figures 1-3 As shown, the wall-mounted air conditioner indoor unit according to an embodiment of the present utility model includes: a housing 1, wherein an air inlet 2 is formed on the top of the housing 1;

[0049] Heat exchanger 3 is disposed inside the housing 1. A top space is defined between the top of the heat exchanger 3 and the air inlet 2 at the top of the housing 1, and a front space is defined between the front of the heat exchanger 3 and the front of the housing 1.

[0050] The sliding track 4 is disposed inside the housing 1. The sliding track 4 includes a top section 41 located in the top space and a side section 42 connected to the top section 41 and located in the front space.

[0051] The filter screen 5 is movably disposed in the sliding track 4, and the filter screen 5 has a top position located at the top section 41 of the track and a side position located at the side section 42 of the track when it moves.

[0052] The first cleaning mechanism 6 is located inside the housing 1 and is used to clean the filter screen 5 when the filter screen 5 moves.

[0053] The second cleaning mechanism 7 is located in the front space and is used to clean the inner wall of the front space.

[0054] Specifically, in the embodiments of this utility model, after installation, the top of the wall-mounted air conditioner indoor unit 1 faces the ceiling, the bottom of the unit 1 faces the base plate, the front of the unit 1 faces the user, and the rear of the unit 1 faces the wall, which is also the side that matches the wall.

[0055] The filter 5 can be a dust filter 5. The air entering the casing 1 from the air inlet 2 can be filtered through the filter 5 to remove dust and large particulate impurities, so as to prevent a large amount of dust from entering the casing 1 and affecting the normal operation of the indoor unit of the air conditioner.

[0056] The filter screen 5 is installed in the sliding track 4 and can move within the sliding track 4. During the movement of the filter screen 5 in the sliding track 4, the first cleaning mechanism 6 can perform friction cleaning on the filter screen 5. That is, when the filter screen 5 needs to be cleaned, it can be moved from the top section 41 of the track to the side section 42 of the track. During the movement of the filter screen 5, the first cleaning mechanism 6 can generate relative friction with the filter screen 5 to clean the filter screen 5, remove a large amount of dust attached to the filter screen 5, and prevent a large amount of dust from accumulating on the filter screen 5, which would not only affect the filtration performance of the filter screen 5, but also affect the air permeability of the filter screen 5, thus affecting the normal operation of the indoor unit of the air conditioner.

[0057] After the first cleaning mechanism 6 cleans the dust on the filter screen 5, the second cleaning mechanism 7 can clean the front space, sweeping off the dust attached to the inner wall of the front space so that the dust can fall downward into the dust collection box 8 at the bottom, thus preventing a large amount of dust from adhering to the front space and polluting the internal environment of the air conditioner indoor unit.

[0058] The first cleaning mechanism 6 and the second cleaning mechanism 7 work together to allow the dust on the filter screen 5 to fall into the dust collection box 8, ensuring the cleanliness of the filter screen 5 and the front space.

[0059] According to an embodiment of this utility model, the wall-mounted air conditioner indoor unit includes a sliding track 4 for the movement of the filter 5, and a first cleaning mechanism 6 and a second cleaning mechanism 7. When the filter 5 needs cleaning, the first cleaning mechanism 6 cleans the moving filter 5, eliminating the need for frequent cleaning by the user and improving the user experience. Simultaneously, the second cleaning mechanism 7 cleans the front space where the track side section 42 is located, removing dust and condensation from the inner wall of the front space. This allows the dust and condensation to continue falling downwards, preventing dirt from accumulating in the front space and affecting the internal environment of the air conditioner indoor unit.

[0060] In some embodiments, the indoor unit of the air conditioner further includes:

[0061] The dust removal bracket 10 and the dust removal cover 11 are fastened together to form the front space, and the dust removal cover 11 is used to separate the heat exchanger 3 and the front space.

[0062] Specifically, the front space is formed by the dust removal bracket 10 and the dust removal cover 11 fastened together. The dust removal cover 11 is close to the heat exchanger 3 and can separate the heat exchanger 3, preventing dust from falling onto the heat exchanger 3 and affecting the normal operation of the heat exchanger 3.

[0063] In some embodiments, the second cleaning mechanism 7 includes: a cleaning roller brush 71 and a first drive motor.

[0064] The first drive motor is mounted on the housing 1 and is used to drive the cleaning roller brush 71 to rotate. The circumferential distribution of the cleaning roller brush 71 contacts the inner wall of the dust removal bracket 10 and the inner wall of the dust removal cover 11. The cleaning roller brush 71 is used to rotate and clean the inner wall of the dust removal bracket 10 and the inner wall of the dust removal cover.

[0065] Specifically, the second cleaning machine drives the cleaning roller brush 71 to rotate via the first drive motor. The cleaning roller brush 71 can scrub the inner wall of the dust removal bracket 10 and the inner wall of the dust removal cover 11, sweeping away the dust and condensation on the inner wall of the dust removal bracket 10 and the inner wall of the dust removal cover 11, thus preventing the accumulation of dust and condensation.

[0066] In some embodiments, the cleaning roller brush 71 includes: a rotating shaft 711 and bristles 712. The rotating shaft 711 is drivenly connected to the first drive motor. The bristles 712 are disposed on the periphery of the rotating shaft 711. While some of the bristles 712 are in contact with the inner wall of the dust removal bracket 10, another part of the bristles 712 are in contact with the inner wall of the dust removal cover 11.

[0067] The rotating shaft 711 is detachably rotatably disposed within the front space.

[0068] Specifically, the cleaning roller brush 71 can be composed of a rotating shaft 711 and bristles 712. The rotating shaft 711 is detachably rotatable in the front space, allowing the user to assemble and disassemble the cleaning roller brush 71. When the cleaning roller brush 71 needs to be cleaned, it can be disassembled for cleaning.

[0069] In some embodiments, there are multiple cleaning roller brushes 71 arranged vertically within the front space.

[0070] Specifically, the cleaning roller brush 71 can be evenly spaced along the vertical direction of the front space to clean various positions on the inner wall of the front space, thereby improving the cleaning effect of the second cleaning mechanism 7.

[0071] In some embodiments, a portion of the cleaning roller brush 71 contacts the inner wall of the dust removal bracket 10, and a portion of the cleaning roller brush 71 contacts the inner wall of the dust removal cover 11.

[0072] The multiple cleaning rollers 71 are arranged alternately in the vertical direction.

[0073] Specifically, such as Figure 3As shown, the multiple cleaning roller brushes 71 can be divided into two groups. One group is close to the dust removal bracket 10 and contacts the inner wall of the dust removal bracket 10, while the other group is close to the dust removal cover 11 and contacts the inner wall of the dust removal cover 11. The two groups of cleaning roller brushes 71 are interleaved, which can clean the front space in different ways and avoid cross-contamination.

[0074] In some embodiments, the indoor unit of the air conditioner further includes:

[0075] Dust collection box 8, which is disposed in the front space, is used to collect dust that falls off when the first cleaning mechanism 6 cleans the filter screen 5 and when the second cleaning mechanism 7 cleans the front space;

[0076] The dust collection box 8 is detachably embedded in the front space.

[0077] Specifically, by detachably placing the dust collection box 8 in the front space of the front of the housing 1, it is convenient for the user to remove the dust collection box 8 and handle the dust in the dust collection box 8.

[0078] In some embodiments, the first cleaning mechanism 6 includes:

[0079] The brush assembly includes cleaning teeth 61, a movable brush 62, and a second drive motor for driving the movable brush 62 to rotate. When driven to rotate, the movable brush 62 has a first cleaning position and a second cleaning position. When the movable brush 62 is in the first cleaning position, it can contact the surface of the filter screen 5 to clean the surface of the filter screen 5. When the movable brush 62 is in the second cleaning position, it can contact the cleaning teeth 61 to clean the movable brush 62.

[0080] Specifically, the first cleaning mechanism 6 can drive the movable brush 62 to rotate via the second drive motor, enabling the movable brush 62 to switch between the first cleaning position and the second cleaning position. When the movable brush 62 switches to the second cleaning position, it can contact the cleaning teeth 61. The cleaning teeth 61 can be multiple protrusions set on the inner wall of the dust removal bracket 10. By contacting the cleaning teeth 61, the movable brush 62 can be cleaned, giving the movable brush 62 a self-cleaning function and extending the service life of the first cleaning mechanism 6.

[0081] In some embodiments, the sliding track 4 further includes a track bending section 43, and the top section 41 of the track is connected to the front section of the track through the track bending section 43;

[0082] Among them, the track bending section 43 is a curved arc structure, and the track bending section 43 protrudes forward of the front side of the front space by a preset distance relative to the track side section 42.

[0083] Specifically, the sliding track 4 consists of a top section 41, a side section 42, and a bent section 43. The bent section 43 bends forward relative to the side section 42 towards the front of the space, preventing dust from falling onto the side section 42 during cleaning of the filter 5. Furthermore, the bent section 43 bends a certain distance further forward from its lower protrusion towards the rear of the space, further preventing dust from falling onto the side section 42. This structure allows the entire sliding track 4 to... The sliding track 4 is designed to form an approximate "S" shape. This shape of the sliding track 4 can not only make full use of the limited space inside the housing 1, reserving sufficient space for the filter 5 to move, avoiding the overall thickness of the housing 1, reducing the space required for the indoor unit of the air conditioner, and improving the user experience, but it can also be used in conjunction with the moving brush 62 set at the bend section 43 of the track. Due to this "S" shaped sliding track 4 design, when dust falls longitudinally, it will not stick to the bottom, i.e., the filter 5 located in the side track section, which can avoid secondary pollution. This allows the dust generated by the moving brush 62 cleaning the filter 5 to fall more effectively from top to bottom.

[0084] In some embodiments, the indoor unit of the air conditioner further includes:

[0085] The driving device includes a roller 9 rotatably disposed between the top section 41 of the track and the side section 42 of the track, and the roller 9 and the filter screen 5 are driven by gear meshing;

[0086] The length of the filter screen 5 is designed such that, when the filter screen 5 is in the top or side position, at least a portion of the filter screen 5 engages with the roller 9 via gears.

[0087] Specifically, by designing the length of the filter screen 5, it can be ensured that the filter screen 58 and the baffle 7 will never come loose during operation.
