When the wall-mounted air conditioner indoor unit 10 works, outside air enters the wall-mounted air conditioner indoor unit 10 to exchange heat with the heat exchanger 12, and then is led out from the opening by the cross-flow wind wheel 15.

In the embodiment of the present invention, as shown in fig. 2, 3 and 4, the wall-mounted air conditioner indoor unit 10 includes a chassis 11, a heat exchanger 12 and an air outlet frame 13, the chassis 11 has upper and lower ends in a width direction thereof, two baffles 11b extending in an up-down direction and facing each other are disposed on the chassis 11, and first sliding portions are disposed on inner surfaces of the two baffles 11 b. The heat exchanger 12 is mounted on the chassis 11, and the chassis 11, the two baffles 11b and the heat exchanger 12 together enclose to form an air duct inner cavity with a downward opening. The air outlet frame 13 is used for installing the cross-flow wind wheel 15, and the two opposite ends of the air outlet frame 13 in the length direction of the chassis 11 are provided with second sliding parts. The air outlet frame 13 and the two baffles 11b are detachably mounted in the air duct inner cavity through the matching of the first sliding part and the second sliding part groove rail.

Specifically, the wall-mounted air conditioner indoor unit 10 is generally rectangular and has left and right ends in a longitudinal direction, upper and lower ends in a width direction, and front and rear ends in a direction perpendicular to a wall when mounted on a wall. The chassis 11 has a bottom plate 11a for being mounted against a wall, the two baffles 11b are a left baffle and a right baffle which are arranged at intervals in the left-right direction, and the two baffles 11b extend forwards from the bottom plate 11 a. The left baffle has the orientation the interior face of right baffle, right baffle also has the orientation the interior face of a face of left baffle all is provided with first sliding part on two interior faces. Here, the first sliding portion may be a guide groove or a boss; that is, the face can all set up the guide slot in two, also can all set up the boss, can also be one of them interior face and set up the guide slot, and the face sets up the boss in another. As for the guide groove, it should be understood that the guide groove is extended to the lower end of the baffle 11 b.

Referring to fig. 5, the air-out frame 13 may be a frame 13a for only installing the cross-flow wind wheel, and on the basis of the frame 13a, the air-out frame 13 may also be formed by combining the frame 13a with at least one of the volute tongue, the air deflector mounting bracket 13d or the water receiving groove 13 c.

Both ends of the air-out frame 13, namely the left and right ends, are provided with second sliding parts matched with the first sliding part groove rails. Here, the second sliding portion may be a guide groove or a boss; that is, both ends can all set up the guide slot about air-out frame 13, also can all set up the boss, can also be wherein one end sets up the guide slot, and the other end sets up the boss.

When the air-out frame 13 is installed in place by the first sliding part and the second sliding part in a sliding manner, the air-out frame 13 can be fixed in the inner cavity of the air duct through a fixing part (such as a screw). When a user needs to disassemble the cross flow wind wheel 15 for cleaning, the fixing piece is only needed to be disassembled firstly, and then the air outlet frame 13 is pulled out from the air duct inner cavity along the first sliding part. After the cross-flow wind wheel 15 is cleaned, the two second sliding parts and the two first sliding parts can be aligned, and then the air outlet frame 13 is pushed to the inner cavity of the air duct from the opening.

Here, the air-out frame 13 may further be provided with a motor mounting position 132 for mounting a wind turbine motor. So, when dismantling tubular wind wheel 15, can dismantle wind wheel motor in the lump, perhaps when wind wheel motor need maintain, directly demolish air-out frame 13, then it is also can with wind wheel motor dismantlement.

According to the technical scheme, the first sliding parts are arranged on the two baffles 11b forming the inner cavity of the air duct, and the second sliding parts matched with the groove rails of the first sliding parts are arranged at the two ends of the air outlet frame 13, so that a user does not need to disassemble the heat exchanger 12 when disassembling the cross-flow wind wheel 15, and only needs to pull the air outlet frame 13 out of the inner cavity of the air duct in a sliding manner, and the disassembling difficulty of the cross-flow wind wheel 15 is greatly reduced.

Referring to fig. 3 to 5, although the first sliding portion may be either a guide groove or a guide rail, the second sliding portion may be either a guide rail or a guide groove. However, for slotting at two ends of the air-out frame 13, the strength of the air-out frame 13 may be reduced, and when the cross-flow wind wheel 15 rotates, if the strength of the air-out frame 13 is low, the stability of the air-out frame 13 may be poor when the cross-flow wind wheel 15 rotates, and in case of serious conditions, the air-out frame 13 may be directly broken. In view of this, in the present embodiment, the first sliding portion is a sliding slot 110 disposed on the inner surfaces of the two baffles 11b, and the second sliding portion is a sliding block 13b disposed at two ends of the air-out frame 13. The sliding block 13b is matched with the sliding groove 110, so that the air outlet frame 13 can freely slide in the inner cavity of the air duct.

In the above embodiments, the sliding block 13b may have various shapes, for example, the sliding block 13b is disposed in a circular shape, the sliding block 13b is disposed in a square shape, the sliding block 13b is disposed in an oval shape, or other irregular shapes may be provided. However, considering that the front side of the air-out frame 13 is the heat exchanger 12 and the rear side is the bottom plate 11a of the base, the air-out frame 13 may touch the heat exchanger 12 or the bottom plate 11a when being installed. Therefore, on one hand, interference may be caused to the sliding of the air-out frame 13, and in addition, the heat exchanger 12 may be deformed or damaged due to the collision of the air-out frame 13 and the heat exchanger 12. In view of this, in the present embodiment, the sliding block 13b is disposed in a non-circular shape, and the sliding block 13b is fixedly installed on the air-out frame 13. Thus, when the air-out frame 13 slides, the sliders 13b are fixed to both ends of the air-out frame 13, so that the air-out frame 13 does not rotate relative to the sliders 13 b. In addition, because the sliding block 13b is arranged in a non-circular shape, the sliding block 13b cannot rotate relative to the sliding groove 110 in the sliding groove 110, and the air outlet frame 13 cannot swing back and forth relative to the first guide rail, so that the air outlet frame 13 is prevented from touching the heat exchanger 12 or the bottom plate 11a of the chassis 11 when sliding. Here, the non-circularly arranged slider 13b is preferably arranged to have an elongated shape in the extending direction of the chute 110.

Referring to fig. 7, in order to further enhance the stability of the sliding block 13b sliding in the sliding slot 110, in this embodiment, a clamping groove is formed on an end surface of the sliding block 13b and one end of the air outlet frame 13, or a clamping groove is formed in the circumferential direction of the sliding block 13b, an inner flange 111 is disposed on a side wall forming the sliding slot 110, and the inner flange 111 extends into the clamping groove and is fastened to the sliding block 13 b.

Considering that when the sliding block 13b slides in the sliding slot 110, a friction force is generated between the slot wall of the sliding slot 110 and the sliding block 13b, on one hand, the air-out frame 13 slides with a large resistance, and the starting is not smooth. On the other hand, a larger number of sliding operations or a longer time period may cause the slide groove 110 or the broken block to deform, thereby making it difficult to slide. In another preferred embodiment, at least one wall surface of the sliding block 13b facing the inner wall of the sliding chute 110 is provided with a ball. The slide groove 110 may have a groove bottom and a side wall adjacent to the groove bottom, and the end surface of the slider 13b facing the groove bottom may be provided with balls, or the wall surface of the slider 13b facing the side wall of the slide groove 110 may be provided with balls.

Referring to fig. 4, the chassis 11 is generally formed through an injection molding process, which causes difficulty in demolding if the slide groove 110 is not linear. In order to facilitate the manufacturing and forming, in the present embodiment, the sliding groove 110 is disposed in a straight line. Moreover, for the sliding slot 110 arranged in a straight line, the sliding of the sliding block 13b of the air-out frame 13 in the sliding slot 110 is smoother.

Referring to fig. 3, the opening of the air duct cavity is usually located at the lower end of the air duct cavity and near the front position, so when the air outlet frame 13 is pushed into the air duct cavity, the moving track of the air outlet frame 13 is inclined upward, in view of the moving track of the air outlet frame 13, the sliding groove 110 should also be inclined upward, the angle α cannot be too large for the inclined angle α of the sliding groove 110, otherwise, the air outlet frame 13 will interfere with the heat exchanger 12 when sliding, the angle α cannot be too small, otherwise, the air outlet frame 13 will interfere with the bottom plate 11a of the chassis 11, in this embodiment, the angle α between the sliding groove 110 and the vertical direction is greater than or equal to 10 ° and less than or equal to 30 °, here, the bottom plate 11a of the chassis 11 has a surface facing and flush with the wall when the wall-mounted indoor unit 10 is mounted on the wall, and the vertical direction is the direction extending downward from the top of the surface.

With continued reference to fig. 3, to facilitate the installation of the slider 13b in alignment with the chute 110, in this embodiment, the chute 110 has a slot that extends through the lower end of the baffle 11b and is flared, where the chute 110 extends from the top to the bottom of the baffle 11b (extends obliquely), the chute 110 has two side walls that extend toward the lower end of the baffle 11b, i.e., a forward side wall and a rearward side wall, the slot of the chute 110 is flared in such a manner that the forward side wall corresponding to the slot of the chute 110 is inclined forward or the rearward side wall corresponding to the slot of the chute 110 is inclined rearward, of course, the angle of inclination β of the forward and rearward side walls is also limited, in one embodiment, the slot of the chute 110 has a guide wall connected to the side wall, the guide wall β is equal to or greater than 3 ° and equal to or less than 10 ° and, for this angle β, the angle β is too small, the guide effect is not significant, and the angle β may interfere with the slider 13b where it connects.

Referring to fig. 5, it is mentioned that the air-out frame 13 may be a frame 13a for only installing the cross-flow wind wheel 15, and on the basis of the frame 13a, the air-out frame 13 may also be a combination of the frame 13a and at least one of the volute tongue, the air deflector mounting bracket 13d or the water receiving tank 13 c. In view of the fact that the baffle plate mounting bracket 13d and the water receiving tank 13c are generally positioned at the air outlet, if the water receiving tank 13c and the baffle plate mounting bracket 13d are not mounted on the frame body 13a, the water receiving tank 13c and the baffle plate mounting bracket 13d need to be removed before the frame body 13a is removed. Thus, the disassembling steps of the cross flow wind wheel 15 are added. In addition, the volute tongue is also frequently required to be disassembled for cleaning.

In view of this, in this embodiment, the air outlet frame 13 includes a frame body 13a for mounting the cross-flow wind wheel 15, a volute tongue, a water receiving groove 13c connected to the volute tongue, and an air guide plate mounting bracket 13d connected to the volute tongue, and the frame body 13a, the volute tongue, the water receiving groove 13c, and the air guide plate mounting bracket 13d are integrally formed. Therefore, when the air outlet frame 13 is detached, the face cover is only required to be opened, the positioning piece for fixing the air outlet frame 13 is detached, and then the air outlet frame 13 is directly pulled out from the inner cavity of the air duct.

Referring to fig. 4 and 5, after pushing out air-out frame 13 into the wind channel inner chamber, in order to facilitate the preliminary location of air-out frame 13, in a preferred embodiment, two the internal surface of baffle 11b all is provided with the bullet and buckles 11c, the both ends of air-out frame 13 all are provided with constant head tank 131, air-out frame 13 passes through bullet buckle 11c with constant head tank 131 is spacing install in the wind channel inner chamber. When the air-out frame 13 enters the inner cavity, the two ends of the air-out frame 13 abut against the elastic buckles 11c, the elastic buckles 11c are elastically deformed, until the air-out frame 13 completely enters the inner cavity, the positioning grooves 131 correspond to the positions of the elastic buckles 11c, and the elastic buckles 11c recover the elastic deformation and enter the positioning grooves 131. Therefore, under the action of the sliding groove 110 and the elastic buckle 11c, the air outlet frame 13 can be initially positioned in the inner cavity of the air duct. Then the user can fix the air-out frame 13 in the air duct cavity through the fixing piece.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
