Fig. 1 is a schematic structural view of an indoor unit of a wall-mounted air conditioner according to an embodiment of the present utility model; FIG. 2 is a schematic structural view of the polymeric column of FIG. 1; FIG. 3 is an enlarged view of the N-N cross-section of FIG. 1; fig. 4 is a schematic view of the wall-mounted air conditioner indoor unit shown in fig. 3 with the polymeric columns and air deflectors 60 hidden.

As shown in fig. 1 to 4, the wall-mounted air conditioner indoor unit according to the embodiment of the present utility model may generally include a housing 10, an air duct 20, a partition plate 70, and at least one connection arm 80.

The casing 10 has an air supply opening 100 penetrating a lower portion of a front wall 101 thereof and a front portion of a bottom wall 102. The front wall 101 of the housing 10 is a wall that faces forward and is typically used to form the front appearance of a wall-mounted air conditioning indoor unit, and the bottom wall 102 of the housing 10 is a wall that faces downward and is typically used to form the bottom appearance of a wall-mounted air conditioning indoor unit. The supply port 100 serves to output an air flow to the outside. The air supply port 100 includes a first side a and a second side f located rearward and downward of the first side a. In other words, the first side a is the lower side of the front wall 101 of the housing 10, and the second side f is the front side of the bottom wall 102 of the housing 10. Of course, the supply port 100 also has two lateral sides, i.e., left and right.

An air duct 20 is located inside the housing 10 for guiding the air flow. The air duct 20 includes a front air duct wall 21 (the inlet and outlet ends of which are indicated by ma in fig. 3) and a rear air duct wall 23 (the inlet and outlet ends of which are indicated by nf in fig. 3) located rearward of the front air duct wall 21. The outlet sides of the front duct wall 21 and the rear duct wall 23 are connected to the first side a and the second side f, respectively. Of course, the duct 20 also includes two lateral side walls, a left duct wall and a right duct wall.

Generally, the housing 10 includes a casing, a framework, and a panel fastened to the casing, which form a structural body, and each duct wall is generally a part of the framework, which are well known in the air conditioning art, and need not be described herein.

The partition plate 70 partitions the air supply port 100 into a forward front air supply port 11 and a downward lower air supply port 12. For example, as shown in fig. 3 and 4, the partition plate 70 may be positioned substantially immediately below the first side a and immediately in front of the second side f so that the front air outlet 11 faces directly forward and the lower air outlet 12 faces directly downward. Of course, the partition plate 70 may be located at other positions, for example, on the line connecting the first side a and the second side f.

One end of each connecting arm 80 is connected to the front duct wall 21 or the rear duct wall 23, and the other end is connected to the partition plate 70 to bear the weight of the partition plate 70.

The wall-mounted air conditioner indoor unit of the embodiment of the utility model utilizes the partition plate 70 to divide the integral air supply port 100 into the front air supply port 11 and the lower air supply port 12, thereby meeting the multi-angle air supply requirements of forward air supply and downward air supply. And the partition plate 70 is mounted on the front air duct wall 21 or the rear air duct wall 23 through the connecting arm 80, so that the design and manufacture of the shell 10 are not affected by multiple air supply outlets, and the design and manufacture difficulty of the shell 10 is not increased. If the partition plate 70 is integrally formed with the housing 10, the strength of the partition plate 70 will be low because the partition plate 70 is generally narrow and thin, and the protection of the partition plate 70 is considered during the whole period of processing and transportation of the housing, resulting in an increase in cost. While the embodiment of the present utility model makes the partition plate 70 independent of the housing 10 and the duct 20, this problem is solved.

In some embodiments, as shown in fig. 3 and 4, the housing 10 defines an accommodating space for accommodating main body parts of the wall-mounted air conditioner indoor unit, including the blower 50, the indoor heat exchanger 40, the controller, and the like. The indoor heat exchanger 40 and the throttle device are connected with a compressor, an outdoor heat exchanger and other refrigerating elements arranged in the air conditioner outdoor unit through pipelines to form a vapor compression refrigeration cycle system. In the case of the heat pump type air conditioner, the indoor heat exchanger 40 functions as an evaporator in the cooling mode. In the heating mode, the indoor heat exchanger 40 functions as a condenser. The housing 10 may be provided with an air inlet 13 for introducing indoor air. Under the action of the fan 50, indoor air enters the interior of the shell 10 through the air inlet, forms heat exchange airflow after forced convection heat exchange with the indoor heat exchanger 40, and is guided by the air duct 20 to be blown out from the outlet of the air duct 20 to the air supply outlet 100. The housing 10 may be generally elongated in a horizontal transverse direction along a length direction, and the air inlet 13 is generally disposed at a top of the housing 10. The air duct is typically a through-flow air duct, and the fan 50 is typically a through-flow fan.

In some embodiments, each connecting arm 80 may be removably connected to either the front duct wall 21 or the rear duct wall 23. For example, the two may be connected by screws or snap-fit means. In this way, in order to realize the air supply of multiple air supply openings, only the partition plate 70 and the connecting arm 80 need to be independently designed and manufactured, and the air duct structure does not need to be improved excessively.

In some embodiments, each connecting arm 80 may be formed as an integral piece with divider plate 70. Because the width of the partition plate 70 is smaller, the connecting arm 80 and the partition plate 70 are made into an integral piece, which is feasible in design and manufacture, and the assembly cost can be saved.

In some embodiments, the number of the aforementioned at least one connecting arm 80 is plural, so that the plurality of connecting arms 80 are arranged in the lateral direction of the housing 10, which can impose more stable constraint on the partition 70 and make its position more firm. Further, the number of the at least one connecting arm 80 may be two, and the two connecting arms 80 are arranged along the lateral direction of the housing 10 and connected to the two ends of the partition plate 70, so that interference of the connecting arms 80 with other components (such as the air deflector 60) at the front air supply port 11 or the lower air supply port 12 can be reduced or avoided as much as possible.

In some embodiments, the wall-mounted air conditioner indoor unit further includes an air deflector 60. The air deflector 60 is disposed at the front air supply port 11 or the lower air supply port 12, and the air deflector 60 is rotatably mounted to the partition plate 70 or the connection arm 80 for rotatably adjusting the air supply angle. In this embodiment, the air deflector 60 is mounted by the partition plate 70 or the connecting arm 80, so that the functions are more abundant and practical.

For example, fig. 3 and 4 illustrate a solution in which the air deflector 60 is mounted to the connection arm 80. Specifically, as shown in fig. 3 and 4, at least one of the connection arms 80 is rod-shaped, and extends out of the lug plate portion 81 for mounting the air deflector 60.

Fig. 5 is an exploded view of the partition plate 70 in fig. 4.

In some embodiments, as shown in fig. 5, the partition plate 70 includes a plate body 71 and a cover plate 72 covered on the outer side of the plate body 71. The plate 71 is adapted to be connected to the connecting arm 80. The cover plate 72 serves as a decoration. Specifically, as shown in fig. 5, two opposite ends of the plate 71 may have two clamping grooves 711 and 712, respectively, so that two flanges 720 are formed by bending opposite sides of the cover plate 72 towards the same side, each flange 720 has two clamping protrusions 721 and 722 on the inner side, and the two clamping protrusions 721 and 722 are respectively clamped into the two clamping grooves 711 and 712, so as to realize the clamping between the cover plate 72 and the plate 71. In alternative embodiments, the cover plate 72 and the plate 71 may be fixedly connected by screws or bonding.

Fig. 6 is a schematic view of the wall-mounted air conditioner indoor unit of fig. 3 when switching to the cooling comfort mode.

In some embodiments, as shown in fig. 3 and 6, adjacent to the front air supply opening 11, the distance between the front duct wall 21 (in particular, the ba section thereof) and the partition plate 70 (i.e., ed) gradually decreases in the air flow direction (i.e., the flow cross section gradually smiles), forming a tapered passage. The wall-mounted air conditioner indoor unit further comprises a polymerization column 30 extending in the transverse direction of the casing 10, and air outlet gaps 201 and 202 are respectively defined with (ba section of) the front air duct wall 21 and the partition plate 70 (ed), and are used for guiding the air flow blown to the front air supply opening 11 to the front air duct wall 21 and the partition plate 70, so that the air flow gradually flows out of the front air supply opening 11 toward the air flow center in a polymerization manner under the guidance of the tapered channel, and a polymerization air supply effect is formed. The gas flow velocity is faster because the polymeric column 30 squeezes the gas flow space of the tapered channel. Under the guidance of the tapered channel, the high-speed air flow gradually converges towards the center direction of the air flow in the outward flowing process to form a converging effect, so that the wind power is very strong, the air supply distance is further, and the requirements of the wall-mounted air conditioner indoor unit on long-distance air supply and strong air supply are met, as shown in fig. 6.

In some embodiments, for the case where the front air supply port 11 is provided with the polymerization column 30, the lower end of each connection arm 80 may be connected to the partition plate 70, and the upper end may be connected to the front air duct wall 21, so that the air guide plate 60 is provided at the lower air supply port 12. Each connecting arm 80 may be further given a backward curved shape to give way to the polymeric column 30.

In some embodiments, as shown in fig. 3, the aggregation column 30 is configured to be rotatable about an eccentric axis X parallel to its length direction, so as to adjust the distance between the aggregation column and the front duct wall 21 and the partition plate 70, and thus the size of the two air outlet gaps 201 and 202. As shown in fig. 2, the end of the polymeric column 30 is fitted with a motor 38 for driving rotation thereof. The outer circumferential surface of the polymeric column 30 includes a first outer convex surface 31 and a second outer convex surface 32 facing opposite directions, and the eccentric axis X is spaced from the second outer convex surface 32 by a distance smaller than that of the first outer convex surface 31. The first outer convex surface 31 and the second outer convex surface 32 are connected at a first top end A1 and a second top end A2, so that the cross-section outline is olive-shaped. The first outer convex surface 31 and the second outer convex surface 32 are similarly "snapped" together in opposite directions.

In some embodiments, as shown in fig. 3, 6 to 9, the wall-mounted air conditioner indoor unit is configured to have at least the following modes based on the fact that the polymeric column 30 is rotatable about the eccentric axis X:

(1) Shut-down mode: the polymerization column 30 is rotated such that the first outer convex surface 31 thereof is directed forward, and the first tip A1 and the second tip A2 are respectively abutted against the closed positions of the front duct wall 21 and the partition plate 70 to close the front air supply port 11 by the polymerization column 30. Causing the deflector 60 to close the lower supply opening 12 as shown in fig. 3. Thus, the air outlet 100 is prevented from being entirely discharged.

(2) Cooling comfort mode: the collective column 30 is rotated to a collective air-blowing position in which the second outer convex surface 32 is directed forward, the air is collective-blown from the front air-blowing port 11, and the air deflector 60 is caused to close the lower air-blowing port 12, as shown in fig. 6.

(3) Refrigeration anti-direct-blowing mode: the first outer convex surface 31 of the polymerization column 30 is upwardly directed so that the air flow mainly flows forward and upward between the polymerization column 30 and the partition plate 70 to form a blow-through preventing effect, and the air deflector 60 is caused to close the lower air supply opening 12 as shown in fig. 7.

(4) Heating down-blowing mode: the polymerization column 30 is rotated to the above-mentioned closed position, and the air guide plate 60 is opened to the lower air supply opening 12 so as to supply air downward, so that the air flow reaches the ground as shown in fig. 8.

(5) Maximum air supply mode: the collective column 30 is rotated to the aforementioned collective air blowing position and the air deflector 60 is opened to the lower air blowing port 12 so that the front air blowing port 11 and the lower air blowing port 12 blow air at the same time.

The embodiment can polymerize multidirectional cold air and nondestructively drop the hot air, realize comfortable external cold and warm distribution (the cold air rises without blowing people, the hot air sinks and falls to the ground easily), and the air supply is rigid and flexible, the distance is near or far, the angle is up or down, the range is large or small, and the technical effect is obvious.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model.
