In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. connected, or integrally connected. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention in specific situations.

An easy-to-clean wall-mounted air conditioner indoor unit provided by an embodiment of the present invention, as shown in Fig. 3, Fig. 4 and Fig. The two axial ends of the flow vane 3 and the cross-flow vane 3 are respectively connected to the two opposite side walls of the inner shell 2. At least one side wall of the inner shell 2 is provided with a through hole 4 corresponding to the axial end of the cross-flow vane 3. The through hole 4 The through-flow blade 3 can pass through, and the mounting plate 5 is detachably connected to the through hole 4, and one end of the cross-flow blade 3 is rotatably connected to the mounting plate 5.

The easy-to-clean wall-mounted air conditioner indoor unit of the embodiment of the present invention, referring to Fig. 3, Fig. 4 and Fig. 5, since at least one side wall of the inner shell 2 is provided with a through hole 4 corresponding to the axial end of the cross-flow fan 3, and The through hole 4 allows the through-flow fan blade 3 to pass through. When cleaning the indoor unit of the air conditioner, the outer cover 1 is removed first, and then the mounting plate 5 detachably connected to the through hole 4 is removed. In this way, the through-flow fan blade 3 can be It can be taken out from the through hole 4 on the inner shell 2. Compared with the prior art, since the mounting plate 5 is located at the through hole 4 at the axial end of the cross-flow fan 3, the mounting plate 5 can be easily removed after the outer cover 1 is removed. disassembly, and is not limited by other internal structures such as the outer cover 1 and the heat exchanger; and after the mounting plate 5 is removed, the cross-flow fan 3 can be easily taken out from the through hole 4 without touching the side wall of the inner shell 2 or other internal structures.

It should be noted that the mounting plate 5 is detachably connected to the through hole 4, and the detachable connection method can be various connection structures, such as a screw structure or a clamping structure. Of course, in order to ensure the normal operation of the cross-flow fan 3, The through-flow fan blade 3 and the mounting plate 5 need to be rotatably connected, so the connection between the mounting plate 5 and the inner shell 2 at the through hole 4 requires high reliability, therefore, screw connection is preferred.

The through-hole 4 needs to allow the through-flow vane 3 to pass through, and its shape can be any shape. However, since the cross-section of the cross-flow vane 3 is circular, in order to facilitate processing and look beautiful, as shown in Figure 4, the through-hole 4 is a circle In addition, in order to ensure that the cross-flow vane 3 can pass through the round hole smoothly, the center of the circle hole is located on the rotation axis of the cross-flow vane 3 , and the diameter of the round hole is greater than the outer diameter of the cross-flow vane 3 .

The mounting plate 5 is connected to the through hole 4 on the inner shell 2, and can be covered on the through hole 4, or embedded in the through hole 4. In comparison, when embedded in the through hole 4, It is difficult to install the mounting plate 5 and the inner shell 2. Therefore, it is preferred that the mounting plate 5 is covered at the through hole 4. At the same time, in order to save material, as shown in Figure 6, the mounting plate 5 is set as a circular plate, and the circular plate is round. The diameter of shape plate is greater than the diameter of circular hole, and like this, mounting plate 5 covers and is located at through hole place, and can install and disassemble with inner shell very aspect. In addition, one end of the cross-flow vane 3 is rotatably connected to the center of the circular plate to ensure the normal operation of the cross-flow vane 3 .

The cross-flow vane 3 is generally driven by a motor, as shown in Figure 5, the end of the cross-flow vane 3 away from the through hole 4 is used to connect the motor 6, and the motor 6 is fixed to the side wall of the inner shell 2, in order to facilitate the disassembly of the cross-flow vane 3 , the connection structure 7 between the motor 6 and the cross-flow fan blade needs to be disassembled more conveniently. Generally, the inner shell 2 is provided with an air outlet 21 in the radial direction of the cross-flow fan blade 3. Therefore, as shown in FIG. 7, the motor 6 The connection structure 7 with the cross-flow fan 3 is arranged close to the air outlet 21 , and the position of the air outlet 21 can be used to facilitate the installation or removal of the motor 6 and the cross-flow fan 3 .

The connection structure between the motor 6 and the cross-flow fan blade 3 can be a conventional connection structure, however, in order to facilitate the operation from the position of the air outlet 21, as shown in Figure 7, the connection structure 7 between the motor 6 and the cross-flow fan blade 3 is a threaded connection , including screws and threaded holes that cooperate with each other, and the operating part of the screw is set close to and facing the air outlet 21, so that the screw can be conveniently operated at the position of the air outlet 21 to install or disassemble the motor 6 and the cross-flow fan 3.

The cross-flow fan blades 3 are arranged in the inner shell 2, and the arrangement method can be arranged in the horizontal direction or in the vertical direction. Generally, when the cross-flow fan blades 3 are arranged in the horizontal direction, the heat exchanger inside the air conditioner is easy to To generate condensed water, it is necessary to set a water collection structure on one side of the cross-flow fan 3, and the water collection structure generally extends beyond the two ends of the cross-flow fan 3, so that the water collection structures located at both ends of the cross-flow fan 3 are in the When the cross-flow fan blade 3 is taken out, it is easy to collide with the cross-flow fan blade 3, thereby damaging the water collection structure and causing water leakage of the indoor unit. Therefore, in order to avoid such problems, as shown in Figure 5, the cross-flow fan blade 3 and the inner shell 2 are arranged in the vertical direction, and a heat exchanger 8 is provided on one side of the cross-flow fan blade 3. The condensed water on the 8 will flow along the heat exchanger 8 to the bottom end of the heat exchanger 8 due to gravity, therefore, only the bottom end of the inner shell 2 corresponding to the heat exchanger 8 needs to be provided with a collector for collecting condensed water. Water structure 9, all the condensed water can be collected. Compared with the scheme in which the cross-flow fan blades 3 are arranged in the horizontal direction, the water collection structure 9 only needs to be arranged at the bottom of the inner shell 2 corresponding to the heat exchanger 8, which greatly simplifies the structure of the water collection structure 9, and the condensed water flows along the heat exchanger. 8 flow, will not reach the two ends of the cross-flow fan 3, and then the setting of the water collecting structure 9 will not affect the taking out of the cross-flow fan 3.

When the cross-flow fan blade 3 is arranged in the vertical direction, one end must be connected to the motor 6 to drive it to rotate. It will be in contact with condensed water, and there is a potential safety hazard. Therefore, in order to avoid this potential safety hazard, as shown in Figure 5, the through hole 4 is opened on the lower side wall of the inner shell 2, and the motor 6 is fixed to the upper side wall of the inner shell 2. , In this way, the motor 6 is located above the cross-flow fan blade and will not come into contact with condensed water.

In order to increase the effect of the wind, there can be multiple cross-flow fan blades 3, for example, as shown in Figure 5, two cross-flow fan blades 3 are arranged side by side, correspondingly, the inner shell 2 corresponds to two cross-flow fan blades 4 respectively Two air outlets 21 are provided.

When the two cross-flow fan blades 3 are arranged side by side, the air outlets 21 are for the convenience of controlling the indoor temperature. As shown in Figure 3, the two air outlets 21 are opened towards the front panel of the outer cover 1. In addition, because the wall-mounted air conditioner The rear panel of the indoor unit is generally installed against the wall, therefore, the air inlet can be arranged on the side wall of the outer cover 1, corresponding to the two cross-flow fan blades 3, preferably, the two side walls of the outer cover 1 are respectively provided with air inlets 11.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily imagined by those skilled in the art within the technical scope disclosed in the present invention shall be covered. Within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope described in the claims.
