Fig. 1 is a schematic view of an air conditioner indoor unit 20 according to one embodiment of the present utility model; fig. 2 is another schematic view of the indoor unit 20 of the air conditioner shown in fig. 1.

Referring to fig. 1 and 2, an air inlet is formed in an indoor unit 20 of an air conditioner according to the present utility model, and generally includes a slide rail 21, a roller shutter 23, and a receiving device 25. The slide rails 21 are disposed on both sides of the air inlet in the length direction. The roller shutter 23 is disposed on the slide rail 21 and configured to move along the slide rail 21 for opening and closing the air inlet. The housing device 25 is provided at one end of the air intake in the longitudinal direction and has a housing chamber for housing the roll screen 23. The storage device 25 comprises a winding motor 251, and the winding motor 251 is used for pulling the roller shutter 23 into the storage cavity.

Referring to fig. 2, two sliding rails 21 are respectively disposed at two sides of the air inlet in the length direction, and two sides of the rolling curtain 23 are respectively mounted on one sliding rail 21. It is understood that the term "on the slide rail 21" herein refers to a positional relationship in which the roll screen 23 is located above the slide rail 21, but refers to a structural relationship in which the roll screen 23 is mated with the slide rail 21. In other words, the slide rail 21 may be formed with a groove, and one end of the roller shutter 23 is made to ride in the groove, not necessarily over the height direction of the slide rail 21.

Since the air conditioner indoor unit 20 needs to suck air from the air inlet when operating, the shutter 23 is required to have an adjustable opening/closing function. The storage device 25 is internally provided with a storage cavity, and when a user turns on the air conditioner 10, the rolling screen 23 can be pulled into the storage cavity to open the air inlet by supplying power to the rolling motor 251. When the air conditioner 10 stops operating, the shutter 23 is required to close and cover the air inlet. If only the busy season and the off season of the air conditioner 10 are considered, the air inlet is closed by manually pulling the roller shutter 23 by a user, so that a better dustproof effect can be achieved. However, in some alternative embodiments, the roller blind 23 may also have the function of automatically closing the air intake, given that some users may wish to close the air intake each time the air conditioner 10 is stopped, if the user is required to manually pull the roller blind 23 each time, which would obviously affect the user's use experience.

For example, in some alternative embodiments, the indoor unit 20 further includes a traction motor disposed at an end of the air inlet remote from the storage device 25 and connected to an end of the roller shutter 23 remote from the storage device 25 by a traction rope, for pulling the roller shutter 23 to close the air inlet.

When the air conditioner 10 is opened, the rolling shutter 23 moves in a direction of opening the air inlet, that is, is gradually accommodated in the accommodating chamber, the traction motor may be not energized or the traction rope may be released in synchronization with the movement of the rolling shutter 23. When the air conditioner 10 is closed and the air inlet is required to be correspondingly closed, the traction motor pulls the roller shutter 23 through the traction rope connected with the end part of the roller shutter 23, so that the roller shutter 23 is pulled out of the accommodating cavity and the air inlet is closed.

During the process of the traction motor traction the roller shutter 23 to close the air inlet, the rolling motor 251 preferably rotates synchronously so as to avoid the stacked roller shutter 23 from being blocked due to overlarge resistance.

In addition to providing a traction motor to draw the roller shutter 23 to close the air inlet, in order to reduce the production cost of the indoor unit 20 of the air conditioner, the winding motor 251 can also bear the function of drawing the roller shutter 23 to close the air inlet. Specifically, in other alternative embodiments, the end of the air intake remote from the receiving device 25 is provided with a pulley or slide bar; the winding motor 251 is connected with one end of the roller shutter 23 far away from the storage device 25 through a traction rope which bypasses a pulley or a sliding rod, and is used for pulling the roller shutter 23 to close the air inlet.

The winding directions of the traction rope and the roll screen 23 are opposite, so that one of the traction rope and the roll screen 23 is wound and the other is released during the rotation of the winding motor 251 in a certain direction.

It should be noted that, the connection between the winding motor 251 and either end of the roller shutter 23 does not limit the direct connection between the rotating shaft of the winding motor 251 and the roller shutter 23, but includes that the winding motor 251 and the roller shutter 23 can be connected in a driving manner via various driving structures such as winding wheels, traction ropes, gears and belts.

Fig. 3 is a partial schematic view of the indoor unit 20 of the air conditioner shown in fig. 1.

For example, referring to fig. 3, in some alternative embodiments, the receiving device 25 further includes a housing 253 and a take-up wheel 255. The housing 253 defines a receiving chamber therein, and the housing 253 is provided with an opening through which the roll screen 23 passes. The winding wheel 255 is disposed inside the housing 253 and connected to one end of the roller shutter 23, for winding the roller shutter 23 on the winding wheel 255. The winding motor 251 is connected with the winding wheel 255 and drives the winding wheel 255 to rotate.

The winding wheel 255 may be a cylindrical roller, and when the winding motor 251 is disposed outside the housing 253 as shown in fig. 2, the winding wheel 255 may be coaxially fixed with the winding motor 251 so as to rotate synchronously, but the two may be connected by a gear transmission. The winding wheel 255 and the winding motor 251 which are in transmission connection are more convenient to install and detach.

One end of the roller shutter 23 is connected to the winding wheel 255, and when the winding wheel 255 rotates, the roller shutter 23 is gradually wound on the winding wheel 255 and gradually opens the air inlet. The take-up reel 255 rotates in a specific direction during the process of taking up and releasing the roll screen 23 (e.g., when the take-up reel 255 is in the illustrated position, the roll screen 23 is taken up and the air intake is opened when the take-up reel 255 rotates counterclockwise).

Since the surface of the roll screen 23 is not generally a continuous smooth plane, a small angle of protrusion on the moving track of the roll screen 23 affects the flexibility of the movement of the roll screen 23. In some alternative embodiments, the opening of the housing 253 is typically spaced a distance and height from the end of the rail 21, and the receiving device 25 further includes a transition plate 257, the transition plate 257 extending from the side of the opening of the housing 253 to the end of the rail 21 and forming a curved surface protruding toward the side of the roller blind 23.

The transition plate 257 has a convex arc surface as a support for the moving track of the roller shutter 23, so that transition can be well formed, and the roller shutter 23 is prevented from being clamped at the edges. The transition plate 257 is generally provided only at one side of the roll screen 23, but may be provided at both sides of the roll screen 23 so as to form a transition of the moving path of the roll screen 23 during both winding and unwinding of the roll screen 23.

Since the roll screen 23 is wound on the winding wheel 255, the housing chamber is preferably provided in a cylindrical shape, and the winding wheel 255 is provided on the axis of the housing chamber, thereby fully utilizing the space in the housing chamber and facilitating the reduction of the size of the housing device 25.

Fig. 4 is a schematic view of a roll screen 23 in the indoor unit 20 of the air conditioner shown in fig. 1; fig. 5 is a schematic partial sectional view of the indoor unit 20 of the air conditioner shown in fig. 1.

The shape of the roll screen 23 includes various kinds, but generally, as shown with reference to fig. 4 and 5, the roll screen 23 includes a plurality of screen pieces 231, and hinges 233 fixed at both ends of each screen piece 231. Two hinges 233 of the same end of each two adjacent curtain pieces 231 are hinged to each other, and the hinges 233 are slidably disposed in the slide rail 21.

The advantage of providing the roller shutter 23 over an integrally formed flexible sheet material is that the shutter pieces 231 of the roller shutter 23 are typically of a hard plastic or metal material, and are not easily deformed, and the roller shutter 23 is rolled up in the receiving device 25 and is not deformed by bending itself but by rotation between adjacent hinges 233 connecting the shutter pieces 231. In contrast, if a flexible sheet material is provided, the sheet material is easily deformed and falls off from the slide rail 21.

Fig. 4 and 5 show hinges 233 in an alternative embodiment, in which the front end of each hinge 233 is inserted into the rear end of another hinge 233, and adjacent two hinges 233 are connected by a rotation shaft so as to be rotatable. The curtain 231 is fixedly connected to the hinges 233 at both ends thereof, and thus also rotates in the same direction as the hinges 233. The thickness of the curtain sheet 231 is generally thin, and does not affect the rotation and movement of the hinge 233 at any position. The sliding rails 21 at two sides of the air inlet respectively form opposite grooves, and the hinges 233 at two sides of the rolling curtain 23 are positioned in the grooves of the two sliding rails 21 so as to move along the sliding rails 21.

It will be appreciated that the specific parameters of the opening size of the housing 253, the shape of the slide rail 21, and the shape of the hinge 233 are adaptively adjustable, and thus are not limited.

In order to avoid that the receiving device 25 pulls the roller shutter 23 out of the slide rail 21, which results in that the roller shutter 23 cannot be reset, as shown in fig. 2 and 3, in some alternative embodiments, the roller shutter 23 forms a limiting plate protruding towards the outside of the air inlet at one end far away from the receiving device 25, and a baffle is arranged between the slide rails 21 near one end of the receiving device 25, the baffle is arranged at the outside of the air inlet close to the roller shutter 23, and is used for blocking the roller shutter 23 at the limiting plate to slide out of the slide rail 21.

The limiting plate may be generally provided on the first or second curtain sheet 231 closest to the end of the roll screen 23, which may be higher than the slide rail 21, and serve as a handle when the user manually pulls the roll screen 23. The height of the baffle may be generally flush with the height of the upper end of the rail 21 or slightly higher than the rail 21. In particular, in some alternative embodiments, the baffle is integrally formed with the housing 253 of the receiving device 25 and extends from the end of the transition plate 257 between the slide rails 21.

Since the roller shutter 23 itself serves to block dust from entering the air conditioner indoor unit 20 through the air inlet, dust is inevitably accumulated on the surface thereof. In some alternative embodiments, the receiving device 25 is disposed outside the air conditioner indoor unit 20 to facilitate cleaning. And further, at least a housing 253 portion of the storage device 25 is detachably provided on the air conditioner indoor unit 20. In some alternative embodiments, the housing 253 of the receiving device 25 is removably disposed relative to the other portions with an opening sized larger than the size of the take-up reel 255, thereby enabling the housing 253 to be removed and separated from the take-up reel 255. The housing 253 of the receiving device 25 may also be provided in two parts that can be spliced for easy disassembly.

When the winding motor 251 of the storage device 25 is disposed outside the housing 253, the storage device 25 may be disposed such that the housing 253 and the winding wheel 255 are detachable from the winding motor 251.

When the housing 253 is removed, the shutter no longer blocks movement of the roller shutter 23, thereby allowing the roller shutter 23 to also be removed from the track 21 for cleaning.

In addition, the end of the roller shutter 23 connected to the winding wheel 255 may be configured to be detachable, so that the roller shutter 23 can be detached from the storage device 25.

If the interior space of the indoor unit 20 is sufficient, the accommodating device 25 may be disposed inside the indoor unit 20, and the housing 253 of the accommodating device 25 may be integrally formed on the body of the indoor unit 20, and an openable and closable movable door may be disposed above or on the side of the housing, and the winding wheel 255 may be detachably disposed with respect to the housing 253, so as to facilitate the disassembly and cleaning of the user.
