The utility model provides a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit is an indoor part of a split wall-mounted room air conditioner and is used for conditioning indoor air, such as refrigeration/heating, dehumidification, purification, fresh air introduction and the like.
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 diagram showing an assembled structure of a casing 200 and a skeleton 300 of a wall-mounted air conditioner indoor unit according to an embodiment of the present utility model; FIG. 3 is an enlarged view at A of FIG. 2; FIG. 4 is an exploded schematic view of FIG. 2; FIG. 5 is an enlarged view at B of FIG. 4; fig. 6 is a schematic view of the back view of the enclosure 200 of fig. 4; fig. 7 is an enlarged view at C of fig. 6.
As shown in fig. 1 to 7, the wall-mounted air conditioner indoor unit according to the embodiment of the present utility model may generally include a frame 300 and a casing 200.
The frame 300 and the casing 200 are components of a casing of the indoor unit, constitute a structural body of the casing, and define an accommodating space of the casing to accommodate components such as a fan, an indoor heat exchanger, and the like. In addition, the housing 200 and the framework 300 also define an air duct having an air inlet 11 and an air outlet 12. In addition, the wall-mounted air conditioner indoor unit may further include a panel 100 which is fastened to an outer surface of the casing 200, such as a front surface, a lower surface, and left and right end surfaces, to form an outer appearance of the wall-mounted air conditioner indoor unit, as shown in fig. 1.
As shown in fig. 4 and 5, the skeleton 300 extends outwardly by at least one mounting post 310, each mounting post 310 being provided with a threaded hole 312.
As shown in fig. 2 and 3, the housing 200 has at least one positioning portion 210, each positioning portion 210 being located opposite one of the mounting posts 310. Obviously, the number of positioning portions 210 is the same as the number of mounting posts 310. Each positioning portion 210 includes a first positioning recess 211, a second positioning recess 212, and a screw hole 213.
The first positioning recess 211 is concavely formed from a surface of the housing 200 facing away from the skeleton 300. For example, the cover 200 is typically mounted to the front side of the frame 300, so that the surface of the cover 200 facing away from the frame 300 is the front surface of the cover 200. The first positioning recess 211 forms a concave cavity as viewed from the front view (view of fig. 3) of the housing 200. The first positioning recess 211 forms a boss as viewed from the rear view (view of fig. 7) of the housing 200.
The second positioning recess 212 is formed recessed inward from a bottom wall (a wall opposite to an opening of the cavity, the first positioning recess 211 further including a peripheral wall) of the first positioning recess 211. It is known that the size of the cavity formed by the second positioning recess 212 is necessarily smaller than that of the cavity formed by the first positioning recess 211, so as to form a stepped structure. The second positioning recess 212 may be made coincident with the center of the first positioning recess 211. And the same is true. The second positioning recess 212 forms a concave cavity as seen from the front view (view of fig. 3) of the housing 200. The second positioning recess 212 forms a boss as viewed from the rear view (view of fig. 7) of the housing 200.
The screw hole 213 penetrates the second positioning recess 212 to allow a screw (not shown) to be screwed to the screw hole 312 after passing through the screw hole 213. The walls of the screw holes 213 are typically unthreaded. After the screw hole 213 is installed, the head of the screw is received in the cavity formed by the second positioning recess 212.
In the wall-mounted air conditioner indoor unit provided by the embodiment of the utility model, the positioning part 210 for penetrating the screw comprises the first positioning concave part 211, the second positioning concave part 212 and the screw hole 213, so that the positioning part 210 is in a three-stage ladder shape, the strength of the positioning part 210 is increased, the deformation in stress is reduced, the protection and positioning of the screw are enhanced, the deformation of the screw is smaller, and the risk of fracture is avoided. The stepped hole structure also enables the screw to be positioned more conveniently, and production efficiency is improved.
In some embodiments, as shown in fig. 2 and 4, both the backbone 300 and the housing 200 are elongated extending in a horizontal lateral direction (x-direction). The number of the mounting posts 310 is plural, and they are arranged in the lateral direction (x-direction) of the skeleton 300. The number of the positioning portions 210 is correspondingly plural, and are arranged along the transverse direction (x-direction) of the housing 200, thus forming a multi-point fixation, and reducing the stress level of each fixation point.
In some embodiments, as shown in fig. 7, the end surface of the bottom wall of the second positioning recess 212 facing the mounting post 310 has a recessed positioning groove 215, alternatively referred to as a positioning hole, for receiving and positioning the mounting post 310. This way. When the housing 200 is aligned with the backbone 300, the mounting posts 310 are inserted into the positioning grooves 215, so that the mounting posts 310 are more easily aligned with the positioning portions 210. And, after the installation is completed. The circumferential walls of the locating slot 215 also constrain the mounting post 310 so that there is no misalignment between the two, thereby reducing the radial shear stress experienced by the screw when the housing 200 and the backbone 300 are misaligned, which is equivalent to protecting the screw.
In some embodiments, as shown in fig. 7, the bottom wall 2151 of the detent 215 is formed with a frosted finish. The surface of the frosted skin texture surface is provided with a plurality of bulges. The frosted skin surface is contacted with the end surface of the mounting column 310 to form a multipoint contact effect, and when the cover shell 200 and the framework 300 generate thermal expansion and contraction, the thermal expansion and contraction noise is smaller.
In some embodiments, as shown in fig. 7, the outer peripheral wall of the first positioning recess 211 extends outwardly a plurality of first reinforcing ribs 2111, so that the strength of the first positioning recess 211 is stronger. For the first positioning recess 211 of the rounded rectangle, the number of the first reinforcing ribs 2111 is preferably 8, and two are provided on each side of the rectangle.
Further, the outer peripheral wall of the second positioning recess 212 extends out a plurality of second reinforcing ribs 2122, so that the strength of the second positioning recess 212 is stronger. Each second reinforcement 2122 is located opposite one first reinforcement 2111, so that the overall strength of the positioning portion 210 is stronger.
As shown in fig. 5, a plurality of third reinforcing ribs 313 extend outwardly from the outer peripheral wall of each mounting post 310. The third reinforcing ribs 313 may be provided in two, and preferably arranged in the lateral direction of the frame 300, so as to resist the load generated by the misalignment of the cover 200 and the frame 300 in the lateral direction more.
In some embodiments, as shown in fig. 3, the cavities formed by the first positioning recess 211 and the second positioning recess 212 may each be rounded rectangular. The fillet radius of the cavity of the second positioning recess 212 is made larger than the fillet radius of the cavity of the first positioning recess 211. In this way, the cavity of the second positioning recess 212 is smaller than the cavity of the first positioning recess 211 but the radius of the rounded corner is larger, so that the first positioning recess 211 is close to square, and the second positioning recess 212 is close to circular. Experiments prove that the structural cooperation makes the overall strength of the positioning part 210 stronger.
In some embodiments, the wall-mounted air conditioning indoor unit utilizes a vapor compression refrigeration cycle system for cooling/heating. An indoor heat exchanger and a fan (not shown) are provided in the casing. The indoor side heat exchanger and the throttling device are connected with a compressor, an outdoor side heat exchanger and other refrigerating elements arranged in the air conditioner outdoor unit through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan, indoor air enters the interior of the shell through an air inlet 11 at the top of the shell, and after forced convection heat exchange with the indoor side heat exchanger is completed, heat exchange air is formed and enters the air duct, and then the air is blown to the indoor environment through an air outlet 12 so as to regulate the indoor environment air.
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.
