Referring to fig. 1 and fig. 2, the present invention further provides an indoor unit 100 of an air conditioner, where the indoor unit 100 of the air conditioner includes a casing 110 and an air guide device. The specific structure of the air guide device refers to the above embodiments. Since the present air conditioning indoor unit 100 adopts all the technical solutions of all the embodiments, all the beneficial effects brought by the technical solutions of the embodiments are also achieved, and are not described in detail herein.

In an embodiment, the housing 110 has an air inlet 101 and an air outlet 102 communicating with the air inlet 101, an air outlet frame 210 of the air guiding device is rotatably mounted in the housing 110 around a rotation axis thereof, and the air outlet frame 210 corresponds to the air outlet 102.

Specifically, the cross section of the housing 110 (as shown in fig. 2) taken by a plane perpendicular to the up-down direction may be circular or square or other irregular shapes. Specifically, the rear end of the cross section is semicircular, and the front end of the cross section is gradually reduced forwards and is arranged in a semi-elliptical shape, so that the cross section is approximately egg-shaped. Thus, the overall size of the air-conditioning indoor unit 100 is reduced, the space occupied by the front end of the air-conditioning indoor unit is reduced, and the whole air-conditioning indoor unit is miniaturized.

An air duct assembly 140 is installed in the housing 110, and the air duct assembly 140 is used to form an air supply duct, which communicates the air inlet 101 and the air outlet 102 of the housing 110. The indoor unit 100 of the air conditioner further includes a wind wheel assembly 130 and a heat exchange assembly 120; the air duct assembly 130 is installed in the air duct assembly 140, and the heat exchange assembly 120 is installed between the air duct assembly 140 and the air inlet 101 of the housing 110.

When the indoor unit 100 of the air conditioner operates, the air wheel assembly 130 drives air to enter the casing 110 from the air inlet 101, and after heat exchange is performed by the heat exchange assembly 120, the air is continuously driven by the air wheel assembly 130 to enter the air supply duct of the air duct assembly 140, and then the air is blown to the air outlet frame 210 from the air supply duct, and finally the air is led out to the indoor space through the air outlet frame 210. In this process, the air outlet frame 210 serves to gather and press the air flow, thereby helping to guide a large amount of air flow toward the area of the air supply required by the user. Meanwhile, air supply to different directions can be realized through the swing of the air guide piece. For example, the wind guide member is a louver 230 that can swing up and down, and the louver 230 can guide wind up and down. Alternatively, the air guide member is an air guide plate 220 capable of swinging in the left-right direction, and the air guide plate 220 can guide air left and right.

Since the air outlet 102 of the housing 110 is elongated and extends vertically, the air outlet frame 210 is also elongated and corresponds to the air outlet 102. Accordingly, the axis of rotation of the outlet frame 210 also extends in the vertical direction. The rotation axis of the air-out frame 210 is a virtual axis for describing the rotation center of the air-out frame 210, i.e. the air-out frame 210 can rotate around the rotation axis. Here, the housing 110 is configured with mounting seats at both ends of the air-out frame 210; the upper end and the lower end of the air-out frame 210 are respectively connected with the corresponding mounting seats in a rotating manner.

Referring to fig. 1 and 3, in an embodiment, the indoor unit 100 of the air conditioner further includes an electric control component 300 mounted on the casing 110, and a lead 251 of the driving device 250 is led out from an end of the air outlet frame 210 and then connected to the electric control component 300 through a connection wire 400. The electronic control unit 300 may include an electronic control box or a display control box, and the electronic control box is mounted on the housing 110.

The wire 251 of the driving device 250 may be led to the electronic control unit 300 directly from the end of the air-out frame 210, or may be connected to the electronic control unit 300 through a connecting wire 400. Here, in order to facilitate connection and installation of the wires 251, the latter connection method may be selected. Based on this, the end of the air-out frame 210 is provided with a wire holder 500 for connecting the conducting wire 251 of the driving device 250, one end of the connecting wire 400 is connected to the wire holder 500, and the other end of the connecting wire 400 is connected to the electric control component 300.

Specifically, a wire holder 500 is provided in one of the mounting cavities 260 of the air-out frame 210, and the wire 251 of the driving unit 250 is connected to the wire holder 500. One end of the connection wire 400 is connected to the wire holder 500 to be connected with the wire 251 of the driving device 250; and the other end of the connecting wire 400 is led out from the air-out frame 210 and connected to the electric control part 300.

Referring to fig. 3 and 6, in an embodiment, since the housing 110 is fixed relative to the air-out frame 210, when the air-out frame 210 rotates, the air-out frame 210 easily drives the connecting wire 400 to move, so that the connecting position of the connecting wire 400 is loosened (the loosened position is, for example, a position a1 of the connecting wire 400 connected to the housing 110 in fig. 7, and a position a2 of the connecting wire 400 connected to the wire holder 500 in fig. 8), so that the connection is unstable.

Referring to fig. 6 and 7, in view of this, the indoor unit 100 of the air conditioner further includes a wire clamping assembly 600, the fixing structure includes a wire clamping base 610 and a wire clamping cap 620, the wire clamping base 610 is suitable for being mounted on the casing 110 or the wire holder 500, a wire clamping groove 611 for passing the connecting wire 400 is configured on the wire clamping base 610, and the wire clamping cap 620 is detachably connected to the wire clamping base 610 to clamp and fix the connecting wire 400 in cooperation with the wire holder 500. The wire clamping cap 620 and the wire clamping seat 610 can be detachably connected by a snap structure or a screw structure, which is not limited herein.

Referring to fig. 6 to 8, it is considered that the connection cord 400 has a position a1 connected with the housing 110 and a position a2 connected with the wire holder 500. When the air-out frame 210 rotates, the air-out frame 210 rotates relative to the housing 110, the air-out frame 210 drives the position a1 of the connection cable 400 to rotate together, and the position a2 of the connection cable 400 is fixed to the housing 110, so that the connection cable 400 is easily damaged due to twisting at the position a1 and the position a1 of the connection cable 400.

Therefore, in order to avoid the above situation, the number of the wire clamping assemblies 600 is two, wherein one wire clamping assembly 600 is configured on the wire holder 500 and is connected with the connecting wire 400 (the connection position of the connecting wire 400 corresponds to the position a 2); another wire clamping assembly 600 is configured on the housing 110 and connected to the other end of the connecting wire 400 (the connecting position of the connecting wire 400 corresponds to a position a 1). Thus, the two ends of the connecting wire 400 are fixed, so that twisting is not easy to occur, and the occurrence of twisting damage can be reduced.

Referring to fig. 6 to 8, in an embodiment, a wire clamping portion 410 may be further formed on an outer peripheral wall of the connection wire 400, the wire clamping portion 410 is suitable for being clamped by a clamping groove 611 of a wire clamping seat 610, and the wire clamping portion 410 is disposed in a polygonal block shape. Since the wire clamping portion 410 of the connecting wire 400 is polygonal, the wire clamping portion 410 has a plurality of side surfaces, and a corner is formed between two adjacent side surfaces. The shape of the wire clamping groove 611 is matched with the wire clamping portion 410, so that the wire clamping portion 410 is not easy to rotate in the wire clamping groove 611, and the effectiveness of the wire clamping assembly 600 in preventing the connecting wire 400 from twisting is improved.

Referring to fig. 7 and 9, it is further contemplated that the connection wire 400 may move along its length within the clamping slot 611 of the wire clamping assembly 600 such that the connection wire 400 may be pulled loose. Here, in order to prevent the connection wire 400 from being pulled and loosened, the opposite sides of the wire clamping portion 410 are configured to form positioning edges 420, and after the wire clamping portion 410 is engaged with the clamping groove 611 of the wire clamping assembly 600, the two positioning edges 420 are respectively located at the two sides of the clamping groove 611 to limit the movement of the connection wire 400 along the length direction thereof. The two positioning edges 420 may be integrally formed with the wire clamping portion 410.

Referring to fig. 10 and fig. 11, of course, in some embodiments, a protective layer 430 may be further formed on an outer surface of the connection line 400 between the two wire clamping portions 410, and the protective layer 430 is made of an elastic material or a flexible material, so that the connection line 400 has flexibility or elasticity, and a torsion acting force generated by the connection line 400 may be buffered, thereby preventing the connection line 400 from being damaged by torsion.

The structure of the protection layer 430 is not limited, and the protection layer 430 may be threaded around the outer circumference of the connection line 400. Alternatively, the protective layer 430 has a plurality of annular portions, and a connecting rib is connected to any two adjacent annular portions. In addition, the protection layer 430 may be a sleeve sleeved on the outer circumference of the connection wire 400.

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.
