Currently, in the prior art, the indoor air conditioning unit generally comprises a panel body, a back shell, and a front panel connected to the panel body. The air conditioning compartment is delimited by the rear case, the panel body and the front panel. Generally, the left and right side wall surfaces of the panel body are designed as a plane, so the indoor unit cannot be moved once by two hands because there is no point of force application on the sides of the main body when it is transported or assembled, in particular when it is placed on the ground, thus not being easy to transport and move. In addition, the unusable space in the two side corners in the compartment of the indoor unit occupies a relatively large area, so that the total volume of the indoor air conditioning unit and the indoor space is not used effectively.

JP 2011094838 A discloses an indoor unit that includes a casing having a front panel on its front surface and the casing includes a pair of flat sections placed respectively in a right side section and a left side section approximately parallel between yes and a decorative board that extends from the flat sections in the right side section and the left side section and projecting outwards in the longitudinal direction of the housing. WO-A-2007/012156 discloses another indoor air conditioning unit provided with a casing having left and right convex parts.

Also, the left and right side walls and the upper wall of the panel body of the indoor air conditioning unit are generally fixed and cannot be removed. Because the left and right side walls of the panel body cannot be removed, the indoor unit cannot be effectively cleaned. Similarly, the top wall where the vent of the indoor unit is located cannot be removed, so that the vent cannot be removed for cleaning after the air conditioner has been used for a long time. Consequently, a lot of dust can accumulate on the air vents and cause a health risk. Also, the side walls and top wall of the air conditioner cannot be replaced, so an ordinary user cannot change the shape of the indoor unit or upgrade the housing once the indoor unit is mounted.

Summary of the invention

In order to overcome the shortcomings of the prior art, an objective of the disclosure is to provide an indoor air conditioning unit that can be upgraded in portable effect and is comfortable to carry and move.

Another purpose of the disclosure is to provide an indoor air conditioning unit according to claim 1 with removable side walls so that a common user can remove the side walls of the indoor air conditioning unit without any tools.

The disclosure provides an indoor air conditioning unit comprising a panel body, a rear housing and a front panel connected to the panel body, wherein the compartment of the indoor air conditioning unit is delimited by the rear housing , the panel body and the front panel; the panel body comprises a left side wall and a right side wall; the outer surface of the left side wall of the panel body is provided with a left convex portion that is convex outward relative to the plane where the outer edge of the left side wall is located; and the outer surface of the right side wall of the panel body is provided with a right convex part that is convex outward relative to the plane where the outer edge of the right side wall is located, each of the left convex parts and right comprises a first convex part located in the middle thereof and a second convex part located on the periphery thereof.

In summary, by providing the convex part or the concave part to the left and right side walls of the panel body, the indoor air conditioning unit is improved in the portable effect and is convenient to carry and move.

In addition, compared to the prior art indoor air conditioning unit, the space unusable in the corners of the air conditioning compartment is eliminated through the convex part and the concave part without changing the length and height, so that the interior space of the indoor unit is used more effectively.

Preferably, the panel body further comprises at least one plate connecting the side wall; and at least one of the left and right side walls is connected to at least one plate that removably connects the side wall of the panel body. Using the removable left and right side walls, which can be removed without removing other parts, the indoor air conditioning unit is easy to remove for cleaning. And a common user can replace the left and right side walls according to their needs and tastes to change the appearance of the air conditioner.

Preferably, the panel body further comprises a plate connecting the top wall, with which the top wall is removably connected. Using the removable top wall, which can be removed without removing other parts, the indoor air conditioning unit is easy to remove for cleaning.

Those skilled in the art may think that the upper convex part may comprise a first convex part located in the middle thereof and a second convex part located on the periphery thereof. By providing the top wall with the convex part, compared to the flat top wall, the top wall with the convex part can increase the area of the vent 16 and reduce wind resistance.

Figure 3 shows an exploded perspective view of the indoor air conditioning unit according to the second embodiment of the disclosure. Similar to the previous embodiment, the panel body 4 of the indoor air conditioning unit 200 also comprises a top wall 3, a right side wall 5 and a left side wall 6. For brevity, only the different parts of the first embodiment are described below, and the same reference numbers refer to the same or similar components.

As shown in Figures 3 and 10, the panel body 4 further comprises a plate 40 connecting the right side wall, a plate 41 connecting the left side wall, and a plate 42 connecting the top wall. The right and left side walls 5, 6 and the top wall 3 are respectively connected to the plates 40, 41 connecting the right and left side wall and the plate 42 connecting the top wall of the panel body 4 so that it can be removed . Optionally, the plate connecting the right side wall and / or the plate connecting the left side wall can be integrated with the plate connecting the upper wall as a whole.

Referring to Figures 4 to 8, the connections of the left and right side walls with the plates connecting the left and right side wall of the panel body 4 are described below. As shown in Figure 4, the left and right side walls are mounted from top to bottom along the top-bottom direction A. The left side wall 6 and the right side wall 5 are symmetrical relative to the vertical center plane of the air conditioning indoor unit, so that only the right side wall 5 is described below.

The number and position of the hooks can be determined as necessary. In the preferred embodiment of figure 5, the right side wall 5 is provided with six hooks 9. Figure 7 shows an enlarged view of a hook 9. The hook 9 is hooked with an adaptation hole 12 in the plate 40 that connects the right side wall of the panel body 4 in Fig. 6 for hooking the right side wall 5 into the plate 40 connecting the right side wall of the panel body 4, so that the right side wall 5 cannot be disengaged from the plate 40 connecting the right side wall. Corresponding to the number of hooks in figure 5, the plate connecting the right side wall of the panel body 4 in figure 6 is provided with six adaptation holes 12. Optionally, the hooks 9 are non-elastic hooks.

When the right side wall 5 is mounted, as shown in figure 4, the right side wall 5 is pushed down relative to the plate connecting the right side wall of the panel body 4 and the hook heads on the right side wall 5 in the corresponding adaptation holes 12 to be reliably hung on the plate 40 that connects the right side wall of the panel body 4 together with the continuous downward movement of the right side wall 5, so that the wall Right side 5 is fixed on the plate 40 that connects the right side wall of the panel body 4 in a removable manner.

As shown in Figures 6 and 8, a hooking element 10 can be arranged on the plate 40 that connects the right side wall of the panel body 4. Accordingly, as shown in FIG. 5, an adapter part 14 of the hooking element is arranged on the inner surface of the right side wall 5 opposite the panel body 4. The elastic hook element 10 is hooked with the adapter part 14 of the hook element. Those skilled in the art can think of various ways to produce the adapter part 14 of the hook element. For example, the adapter part of the hooking element may be a gap, a hole, a concave part or an opening and the like between the projections to implement a fixing fit.

Preferably, as shown in FIG. 5, the adapter part 14 of the hook element is delimited by two pairs of limit ribs 22 on the inner surface of the right side wall 5. The elastic hook element 10 is in a clamping fit in the adapter part 14 of the hook element so as to prevent the right side wall 5 from moving relative to the plate 40 connecting the right side wall of the panel body 4 in front-rear direction and top-bottom direction. Although the arrangement of the hooks 9 on the right side wall and the formation of the adaptation holes 12 in the plate connecting the right side wall of the panel body have been described above, those skilled in the art can think of swap the two components. This also applies to the designs of the elastic hook element 10 and the adapter part 22 of the hook element. Those skilled in the art can change the number and position of the components as necessary.

By providing the left and right side walls with the convex parts, as shown in Figure 6, internal parts can be placed in the convex space of the side walls by producing a hole 15 in the panel body 4. Compared to the prior art, the convex part can use the space on both sides of the indoor air conditioning unit more effectively without changing the length or width of the indoor unit, thereby reducing dead space useless.

Referring to Figures 4, 9 and 10, the mounting of the upper wall 3 on the plate 42 connecting the upper wall of the panel body 4 is described below. Reference number 11 in figure 9 refers to the upper convex part of the upper wall.

As shown in Figure 4, the upper wall 3 is mounted on the plate 42 connecting the upper wall of the panel body 4 from the highest to the lowest. The upper wall 3 is provided with a hook 23 and a hook 17. The hooks 23, 17 correspond to the adapter holes 13, 19 in the plate 42 connecting the upper wall respectively so that the upper wall is connected to the plate 42 connecting the upper wall in a detachable way. Optionally, hook 17 is an elastic hook.

In addition, as shown in Figure 5, a reinforced rib 18 may be further provided on each of the left and right side walls to improve strength.

Additionally, clamping bolts and positioning holes can also be formed in each of the left side wall 6, right side wall 5, top wall 3 and panel body 4 for connection and positioning.

Furthermore, as shown in figure 12, the right side wall with the convex part can comprise a convex skirting 20, both can be connected to each other by gluing, welding, a hooking element or other forms of connection.

Although the left and right side walls are connected in such a way that they can be removed By combining hooks with adapter holes and clamping fit in the above embodiment, those skilled in the art can think of other ways of detachable connection, such as combining a sliding track with a sliding part. Similarly, the top wall can also adopt the clamping adjustment mode or the combination mode of a sliding track with a sliding part the same of the left and right side walls.

The above embodiments are intended to explain disclosure clearly rather than to limit disclosure. The scope of protection and concepts of disclosure will be recorded in the disclosure claims.
