The invention provides a wall-mounted air conditioner indoor unit and a wall-mounted air conditioner including the indoor unit of the wall-mounted air conditioner.

Referring to Fig. 1, a wall-mounted air conditioner indoor unit 10 generally has a chassis 11, a mask 12, a heat exchanger 13, a wind wheel 14, a water receiving tank 16, a wind deflector mounting bracket 15, and a wind deflector (not shown). The heat exchanger 13 is mounted on the chassis 11 and is enclosed with the chassis 11 to form a duct. The wind prop has an air outlet 110 (see Figures 4 and 5). The wind wheel 14 is installed in the air duct, and the water tank 16 and the air guide are connected. The board mounting brackets 15 are all mounted at the air outlets 110. When the wall-mounted air conditioner indoor unit 10 is in operation, the outside air enters the interior of the wall-mounted air conditioner indoor unit 10 and exchanges heat with the heat exchanger 13, and is then taken out from the air outlet 110 by the wind wheel 14. The water receiving tank 16 receives the condensed water produced by the heat exchanger 13 during this process, and the air deflector is yawed at the air outlet 110 to expand the air supply range.

In the embodiment of the present invention, as shown in FIGS. 1 and 2, the wall-mounted air conditioner indoor unit 10 includes a chassis 11, a heat exchanger 13, a wind wheel 14, a wind guide mounting bracket 15, and a water receiving groove 16. The heat exchanger 13 is mounted on the chassis 11, and the heat exchanger 13 is enclosed with the chassis 11 to form an air duct. The wind prop has an air outlet 110 extending along the longitudinal direction of the chassis 11. The wind deflector 14 is disposed in the air duct; the air deflector mounting bracket 15 is disposed at the air outlet 110 and detachably connected to the chassis 11; the water tank 16 is detachably mounted on the air duct The air outlet 110 is located between the heat exchanger 13 and the wind deflector mounting bracket 15 . The minimum width D1 of the air outlet 110 is greater than the diameter of the wind wheel 14.

Specifically, referring to FIGS. 2 and 3, the wind wheel 14 refers to a cross flow wind wheel 14, and the cross flow wind wheel 14 is driven by a wind turbine motor 17. The chassis 11 is provided with two end plates (a first end plate 111 and a second end plate 112) constituting a duct, and the two end plates are limitedly mounted by the wind wheel 14, wherein the outer side of the second end plate 112 has a wind wheel motor 17 Mounting position, the motor shaft 171 of the wind turbine motor 17 is coupled to the wind wheel 14 through the second end plate 112. When the wind wheel 14 needs to be disassembled, the mask 12 is first opened, the heat exchanger 13, the water tank 16 and the air deflector mounting bracket 15 are leaked, and then the water tank 16 and the air deflector mounting bracket 15 are removed to remove the air outlet 110. Bare to further disassemble the wind wheel 14.

For the disassembly of the wind wheel 14, the wind wheel 14 may be detached separately, or the wind turbine motor 17 to which the wind wheel 14 is attached may be directly detached.

For the separate disassembly of the wind wheel 14, since the wind wheel 14 and the motor shaft 171 of the wind turbine motor 17 are generally connected by a locking screw 19, the locking screw 19 is disassembled with a screwdriver, and then the wind wheel will be removed. The motor shaft 171 of the motor 17 is pulled out from the shaft hole of the rotor 14, and the user can take the wind wheel 14 out of the air duct. Here, it should be noted that the wind wheel 14 has a certain moving space in the air passage, and after the locking screw 19 is detached, the position of the wind wheel 14 can be moved left and right (moving the wind wheel in the longitudinal direction of the chassis 11) 14), so that the motor shaft 171 is disengaged from the shaft hole, and then the wind wheel 14 is taken out.

For the overall disassembly of the wind wheel 14 and the wind turbine motor 17, after the air outlet 110 is exposed, it is necessary to disassemble the motor cover 18 on which the motor is mounted, and then the wind wheel 14 and the wind turbine motor 17 are integrally removed. It is also possible to disassemble the locking screw 19 after the air outlet 110 is exposed, so that the motor shaft 171 is inserted deeper into the shaft hole, so that the wind wheel 14 and the wind turbine motor 17 are closer to each other, and other structural members are prevented from being dismantled. put one's oar in.

The technical solution of the present invention sets the maximum width of the air outlet 110 to be smaller than the diameter of the wind wheel 14; on the other hand, the water receiving socket 16 and the air deflector mounting bracket 15 are detachably mounted on the air outlet 110, thus releasing The obstruction of the wind wheel 14 being removed from the air duct. When the user needs to clean the wind wheel 14, the heat exchanger 13 does not need to be disassembled, thereby avoiding the risk of the heat exchanger 13 being damaged due to disassembly, thereby improving the service life of the wall-mounted air conditioner.

Referring to Fig. 2, in general, the wind wheel 14 needs to be removed for disassembly, and the wind turbine motor 17 may sometimes need to be disassembled for maintenance. It is not necessary to simultaneously disassemble the wind wheel 14 and the wind turbine motor 17 each time the wind wheel 14 is disassembled. Further, in the above embodiment, the overall disassembly of the wind wheel 14 and the wind turbine motor 17 may be difficult to handle because the interference structure of the wind wheel 14 and the wind turbine motor 17 is generally different. For example, the interference with the wind wheel 14 is generally the first end plate 111 (interference with the shaft 141 of the wind wheel 14), and the interference with the wind turbine motor 17 is the second end plate 112 (for the wind wheel) The motor shaft 171 of the motor 17 generates interference). In view of this, one end of the chassis 11 is provided with a motor mounting cavity for housing the wind turbine motor 17, and a motor cover 18 for covering the motor mounting cavity, and the heat exchanger 13 is mounted to the chassis 11 The motor cover 18 is detachable with respect to the chassis 11 (the heat exchanger does not interfere with the removal of the motor cover). That is, regardless of whether the wind wheel 14 needs to be disassembled, the user can disassemble the locking screw 19, pull the motor shaft 171 out of the wind wheel 14, and then disassemble the motor cover 18, so that the wind turbine motor 17 can be separately removed. . For the embodiment in which the motor cover 18 is detachable relative to the chassis 11 when the heat exchanger 13 is mounted to the chassis 11, the heat exchanger 13 and the heat exchanger 13 may be in the longitudinal direction of the chassis 11 The motor mounting cavity is spaced apart; or, in the longitudinal direction of the chassis 11, the heat exchanger 13 partially extends to the motor mounting cavity. When the motor cover 18 needs to be disassembled, the screw on the motor cover 18 is first removed, and then The motor cover 18 can be pulled out as a whole.

In one embodiment, the water drain 16 is detachably mounted in the air outlet 110. For example, the water tank 16 is detachably connected to the chassis 11, and the water tank 16 is detachably connected to the wind deflector mounting bracket 15. For the embodiment in which the water receiving socket 16 is detachably connected to the chassis 11, the water receiving tank 16 may be detachably connected to at least one of the two end plates, or may be detachably connected to the bottom of the chassis 11 directly through the connecting rod. For the embodiment in which the water receiving socket 16 and the air guiding plate mounting bracket 15 are detachably connected, the water receiving socket 16 and the air guiding plate mounting bracket 15 may be provided with screw holes, and the two are connected by screws. The water tank 16 is provided with a buckle groove, and the air guide plate mounting bracket 15 is provided with a buckle, and the two are buckled and fastened by the buckle.

In another preferred embodiment, referring to FIG. 6 and FIG. 7, in order to facilitate the disassembly of the water receiving trough 16 and the air deflector mounting bracket 15, the water receiving trough 16 is integrally formed with the wind deflector mounting bracket 15. That is, when the two are in injection molding, they are integrally injection molded by a mold.

As the working time of the wall-mounted air conditioner indoor unit 10 is longer, the more condensed water in the water tank 16 is, and after the condensed water is accumulated to a certain extent, the condensed water generated by the heat exchanger 13 falls to the water tank 16 and the water drops It may spill from the sink 16 . Spilled water droplets will blow out from the air outlet 110 with the airflow, which will affect the user experience. In view of this, in the present embodiment, the chassis 11 has upper and lower ends in the width direction thereof, and the water receiving groove 16 has a bottom plate 16a, an inner side plate 16c, and an outer side plate each extending in the longitudinal direction of the chassis 11. 16b, the outer side plate 16b extends obliquely upward from the bottom plate 16a in a direction away from the chassis 11, and the inner side plate 16c is disposed in parallel with the outer side plate 16b. One side of the heat exchanger 13 on the air outlet 110 overlaps the inner surface of the outer side plate 16b. Thus, when the heat exchanger 13 generates condensed water, the outer side plate 16b has a drainage effect on the condensed water, and the condensed water can flow into the water receiving tank 16 along the inner surface of the outer side plate 16b of the water receiving tank 16. Even if the water level in the water tank 16 is high, no water droplets will splash. It should be noted that the water tank 16 may not have the inner side plate 16c, that is, the water receiving tank 16 is disposed in a V shape. Of course, in order to make the capacity of the water receiving tank 16 larger, the water receiving tank 16 is preferably arranged in a U shape, that is, the water receiving tank 16 includes a bottom plate 16a, an inner side plate 16c and an outer side plate 16b, and two baffles located in the longitudinal direction of the chassis 11. (not shown in the figure).

Referring to Fig. 7, since the water receiving tank 16 is located at the air outlet 110, when the wind wheel 14 rotates, a part of the airflow is directly blown into the water receiving tank 16 for the V-shaped water receiving tank 16, thereby increasing the wind resistance on the one hand, and Noise may be produced. On the other hand, when the water level in the water receiving tank 16 is high, condensed water may overflow.

For the U-shaped water receiving tank 16, blowing to the inner side plate 16c of the water receiving tank 16 may increase the wind resistance in the air passage, which may cause eddy currents in the air passage to generate noise. Here, in order to avoid the above, the connection of the inner side plate 16c and the bottom plate 16a is chamfered. Thus, when the airflow is blown toward the inner side plate 16c, on the one hand, due to such an inclined arrangement of the inner side plate 16c, it is possible to guide the air flow, thereby reducing the wind resistance, and on the other hand, the connection between the inner side plate 16c and the bottom plate 16a. The chamfering arrangement can further reduce the wind resistance, and the airflow can flow to the air outlet 110 in response to the chamfer.

Since the heat exchanger 13 and the water tank 16 are often vibrated when the wall-mounted air conditioner indoor unit 10 is in operation, noise is often generated due to unsound assembly. In an embodiment, in order to make the installation of the water tank 16 stronger to reduce noise, the water tank 16 further has an inner side plate 16c parallel to the outer side plate 16b, and the inner side plate 16c and the outer side plate. An abutting plate 16d extending between the 16b and extending in the longitudinal direction of the chassis 11, and an end of the abutting plate 16d remote from the bottom plate 16a abuts against the heat exchanger 13. Thus, the abutting plate 16d and the outer side plate 16b of the water receiving tank 16 are all in contact with the heat exchanger 13, and the water tank 16 and the heat exchanger 13 are more firmly installed, have better stability, and have lower noise.

Referring to Figures 2 and 7, the two end plates of the chassis 11 described above may have a defining effect on the wind wheel 14, and the movement of the wind wheel 14 is limited to between the end plates. The manner in which the wind wheel 14 is taken out from the air duct is moved in the left and right directions (in the longitudinal direction of the chassis 11) to disengage the motor shaft 171 from the shaft hole, and the retaining position can be opened on the both end plates. The groove is for releasing the first end plate 111 to the shaft 141 of the wind wheel 14, and the second end plate 112 to interfere with the motor shaft 171. However, it is obvious that this arrangement is detrimental to the stability of the installation of the rotor 14 and the motor. In view of this, in one embodiment, the length of the wind wheel 14 is less than the length of the air duct. Here, the length of the wind wheel 14 refers to the absolute length of the entire wind wheel 14 (including the length of the shaft 141 thereof), and the length of the air passage refers to the distance between the two end plates. Thus, after the motor shaft 171 is pulled out from the shaft hole, the wind wheel 14 can be directly taken out from the air outlet 110.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalent structural transformation, or direct/indirect use, of the present invention and the contents of the drawings are used in the inventive concept of the present invention. It is included in the scope of the patent protection of the present invention in other related technical fields.
