Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner indoor unit. Background Art

[0002] At present, when a conventional air conditioner indoor unit heats or cools the indoor environment, air circulates between the air conditioner indoor unit and the indoor environment to adjust the indoor temperature and humidity. To prevent the leakage of cold or heat to the outdoor environment, users usually close the door and window. Therefore, after using the air conditioner indoor unit for a long time, the internal components of the air conditioner indoor unit accumulate a lot of dust, which is easy to breed bacteria, making the internal cleanliness of the air conditioner indoor unit poor, and easily contaminating the air blown out from the air conditioner indoor unit, thereby causing the air quality of the air outlet of the air conditioner indoor unit to be poor, which is extremely detrimental to human health.

[0003] Therefore, air-conditioning indoor units with cleaning functions have appeared on the market. By installing a water washing device in the air-conditioning shell, the internal components of the air-conditioning indoor unit can be cleaned to achieve a sufficient cleaning effect. However, since there is a certain gap between the air guide plate of the air-conditioning indoor unit and the air-conditioning shell, high-pressure water flow will impact the air guide plate during the cleaning process, causing the air guide plate to move, causing water in the air-conditioning shell to flow out, thereby reducing the sealing of the air-conditioning indoor unit shell. Summary of the invention

[0004] The main purpose of the present invention is to provide an air conditioner indoor unit to solve the problem of poor sealing of the shell of the air conditioner indoor unit in the prior art.

[0005] In order to achieve the above-mentioned purpose, the present invention provides an air conditioner indoor unit, comprising: a casing; an air guide plate, at least a portion of the air guide plate is installed on the casing, and a gap is provided between the air guide plate and the casing; a sealing device, at least a portion of the sealing device is installed on the casing and opposite to the gap, and the sealing device has a shielding portion, which is movably arranged along a predetermined trajectory to shield or avoid the gap.

Such an arrangement can shield the gap 3 between the air guide plate 2 and the casing 1 through the shielding portion 40 when the air guide plate 2 is not working, thereby preventing dust from falling into the casing 1 through the gap 3, and also preventing condensed water or clean water in the casing 1 of the air conditioner from leaking out of the gap 3, thereby improving the sealing performance of the casing of the indoor unit of the air conditioner.

[0027] like Figure 2 As shown, the shielding portion 40 includes: a first shielding portion 41, which is located on the inner side of the housing 1; and / or a second shielding portion 42, which is located on the outer side of the housing 1. The first shielding portion 41 shields the gap to prevent the water flow inside the housing 1 from flowing out of the gap 3, and the second shielding portion 42 is provided to support the air guide plate 2 to prevent the high-pressure water flow inside the housing 1 from impacting the air guide plate 2 and causing the air guide plate 2 to deform.

[0028] In the embodiment provided by the present invention, the first shielding portion 41 and / or the second shielding portion 42 is a plate body, and the first shielding portion 41 and / or the second shielding portion 42 are in the same extension direction as the air guide plate 2. Such an arrangement can ensure that the first shielding portion 41 and / or the second shielding portion 42 completely shields the gap 3, thereby ensuring the sealing performance of the air conditioner casing 1.

[0029] In the specific implementation process, the sealing device 4 further includes: a driving assembly 43, the driving assembly 43 is mounted on the housing 1, and the driving assembly 43 is connected to the shielding portion 40 to drive the shielding portion 40 to move; wherein, the driving assembly 43 is divided into two groups, and the two groups of driving assemblies 43 are respectively mounted at the two ends of the housing 1. The shielding portion 40 is driven to move by the driving assembly 43 to achieve shielding or avoiding the gap 3 by the shielding portion 40. The driving assembly 43 is divided into two groups, and the two groups of driving assemblies 43 are respectively mounted at the two ends of the housing 1, which can also ensure the stability of the shielding portion 40 during the movement.

[0030] In an embodiment provided by the present invention, the shielding portion 40 includes a first shielding portion 41 located on the inner side of the housing 1 and a second shielding portion 42 located on the outer side of the housing 1, and the driving assembly 43 includes: a first driving member 430, at least a portion of the first driving member 430 is located on the inner side of the housing 1, and the first driving member 430 is drivingly connected to the first shielding portion 41; and a second driving member 431, at least a portion of the second driving member 431 is located on the outer side of the housing 1, and the second driving member 431 is drivingly connected to the second shielding portion 42. The first shielding portion 41 and the second shielding portion 42 are driven by the first driving member 430 and the second driving member 431 respectively, so that the movement of the first shielding portion 41 and the second shielding portion 42 can be controlled simultaneously, and the movement of the first shielding portion 41 or the second shielding portion 42 can also be controlled separately, so that the shielding portion 40 can adjust the shielding form of the gap 3 according to user needs.

[0031] In another embodiment provided by the present invention, the first driving member 430 is a driving gear, and the second driving member 431 is a driven gear, and the driving gear and the driven gear mesh with each other. This arrangement can ensure the synchronization of driving the first shielding portion 41 and the second shielding portion 42, and has a simple structure and is easy to install.

[0032] Specifically, Figure 2 and Figure 4 As shown, the shielding portion 40 has an initial position and a shielding position. When the shielding portion 40 is in the initial position, the shielding portion 40 is in contact with the surface of the housing 1; when the shielding portion 40 is in the shielding position, at least part of the shielding portion 40 is in contact with the plate surface of the air guide plate 2. This arrangement enables the shielding portion 40 to avoid the air outlet during the operation of the air conditioner indoor unit, thereby avoiding wind resistance to the air outlet of the air conditioner and affecting the user's use.

[0033] In the specific use process, the air conditioner indoor unit also includes: a water washing device 5, which is arranged in the housing 1 to clean the housing 1; when the water washing device 5 is in the working mode, the shielding part 40 is located in the shielding position. Specifically, the water washing device 5 is opposite to the cross flow blade 6, and the sealing device is located below the cross flow blade 6. The shielding part 40 prevents the water flow generated by the water washing device 5 from flowing out of the gap 3, and the shielding part 40 can also support the air guide plate 2 to prevent the high-pressure water flow in the water washing device 5 from rushing into the air guide plate 2, causing the air guide plate 2 to deform or open.

[0034] Preferably, the shielding portion 40 has a guide surface, which is an arc-shaped surface. The guide surface is arranged on the first shielding portion 41, so that the washing device 5 can guide the water flow during operation to prevent the water flow from gathering on the first shielding portion 41.

[0035] In the embodiment provided by the present invention, the shielding portion 40 is a shielding plate, and the shielding plate is an arc-shaped plate, so that when the shielding plate shields the gap 3, the surface of the shielding plate fits with the surface of the air guide plate 2. The gap 3 can be further sealed and the supporting effect of the air guide plate 2 can be improved.

[0036] Specifically, the first shielding portion 41 is a first shielding plate having a connecting end and a free end. The first shielding plate is connected to the casing 1 via the connecting end. The thickness of the first shielding plate gradually decreases from the connecting end to the free end to guide the water flow on the first shielding plate.
