In some instances, the principles of the air conditioner, etc., which are well known to those skilled in the art, are not described in detail, so as to highlight the gist of the present invention.

Referring to Figures 1 to 5, Figure 1 shows a schematic structural view of a window machine according to an embodiment of the present invention, Figure 2 shows a schematic structural view of a window machine according to an embodiment of the present invention, and Figure 3 shows an implementation of the present invention Figure 4 shows a partial schematic diagram 1 of a housing in a window machine according to an embodiment of the present invention, and Figure 5 shows a partial view of a window machine according to an embodiment of the present invention Schematic 2. As shown in FIGS. 1 to 5 , the window machine 100 mainly includes an indoor part and an outdoor part integrated in the same housing. First of all, it needs to be explained that as the functional components of the window machine, the compressor, the indoor heat exchanger, the outdoor heat exchanger, the throttling components (such as capillary tubes, electronic expansion valves, etc.) Through the valve, through the circulation of the refrigerant in the circuit formed by the compressor-condenser-throttling component-evaporator-compressor, with the phase change of the refrigerant, it can release cooling/heating to the surface of the indoor heat exchanger . By switching the communication mode of the four-way valve, the window unit can be in a conventional cooling mode and a heating mode. Specifically, when the refrigerant circulates along the circuit of compressor→indoor heat exchanger→outdoor heat exchanger→compressor, the window unit is in a heating cycle. That is: when the window unit is in heating mode, the indoor heat exchanger acts as a condenser that emits heat. And when the refrigerant circulates along the circuit of compressor→outdoor heat exchanger→indoor heat exchanger→compressor, the window machine is in the refrigeration cycle. That is: when the window unit is in the cooling mode, the indoor heat exchanger acts as an evaporator for distributing cooling capacity.

In a possible implementation, the housing includes a roughly U-shaped shell 1, a bottom plate 2 at the bottom of the shell, a back plate 3 at the rear of the shell (outdoor side), and a front panel at the front of the shell. 4. Among them, the casing 1 is provided with an outdoor communication structure 51 that allows the surface of the outdoor side heat exchanger of the outdoor part to exchange heat with the air of the outdoor environment, and the front panel 4 is provided with a structure that allows the outdoor part of the outdoor side heat exchanger to exchange heat with the air in the outdoor environment. Indoor communication structure 52 whose surface exchanges heat with the air in the indoor space. As in this example, both the outdoor connecting structure 51 and the indoor connecting structure 52 are grid-like structures.

Different from the split type air conditioner, the window unit is based on the integrated setting of the outdoor part and the indoor part. By fixing it to the window of the room, the outdoor part can be connected with the outdoor environment, and the indoor part can be connected with the indoor space. For example, a plurality of clamping structures 6 are usually provided on the cover 1, so as to realize the fixing of the window machine on the window of the room. As in this example, the structural form of the clamping structure is as follows: three strip-shaped holes extending and arranged in the vertical direction are respectively provided on the left and right sides of the U-shaped structure of the casing 1, and the casing corresponds to the strip-shaped holes. A pair of snap-in pieces facing each other extends from the position of the hole. When the window machine is fixed to the position corresponding to the window in the room, both sides of the window glass in the room are sandwiched between the pair of snap-in tabs.

In a possible implementation, according to the orientation shown in FIG. 3 , the casing 1 includes a casing body 10 , from the front sides of the casing body corresponding to the ends on both sides of the U-shaped structure to the direction close to the back plate. The extended first casing extensions 11 (a, b) and the second casing extensions 12 ( a, b). Taking the first case extension part 11(b) as an example, it mainly includes a first part 111 located above and a second part 112 near the bottom plate, wherein the first part is mainly used to implement the first case extension part 11 ( b) Fixed connection with the backplane, the second part is mainly used to realize the abutment between the first casing extension part 11(b) and the backplane. Exemplarily, the first part is a strip-like structure with equal width, and the second part is a strip-like structure whose width at the end of the first part is narrower than that of the first part.

In a possible implementation manner, the base plate 2 includes a base plate main body 20, a first base plate extension portion 21 (corresponding to the side of the back plate) extending upward from the portion of the base plate main body between the two sides corresponding to the U-shaped structure, and and two second bottom plate extensions 22 corresponding to the two sides of the U-shaped structure. The first shell extensions 11 (a, b) are connected to the backboard and abut against the outer walls of the two ends of the first bottom plate extension 21, and the second shell extensions 12 (a, b) pass through the second shell respectively. The two base plate extensions 22 are abutted against the positions of the base body 20 corresponding to two sides of the U-shaped structure.

Mainly refer to FIG. 4 , which shows the connection relationship of the part of the housing near the right side. The first bottom plate extension portion 21 has an extended end 211 near the intersection of the back plate and the casing (the edge on the right side of the casing). For example, the extended end has a substantially trapezoidal structure. The first part 111 of the first casing extension 11 (b) and the back plate 3 are fixedly connected at the first position by means of the first screw 71 (b), and the protruding end 211 of the first bottom plate extension 21 is connected to the back plate 3 The connection is fixed at a second location below the first location by means of a second screw 72(b). At the same time, the second portion 112 abuts against the right side portion of the protruding end 211 .

According to the orientation in Figure 4, in this example, there is a gap between the lower side of the first part and the upper bottom of the protruding end, so it can effectively prevent the gap between the fixed connection corresponding to the first position and the second position. interference occurs. The left side of the second part abuts against the right waist of the protruding end but does not abut on a large area. Such cooperation can effectively prevent the difference between the fixed connection mode corresponding to the second position and the abutment mode corresponding to the second position. Interference occurs.

In addition, the position where the base body 20 abuts against the second housing extension 12 (b) is slightly higher than its portion close to the first base extension 21, so that, in the assembled state, the base body 20 The abutting second casing extension part 12 (b) is in a suspended setting not in contact with the ground, because the second casing extension part 12 (b) will not contact with the bottom such as the window or the bottom of the vehicle during transportation, the ground, etc. contact, so the reliability of the abutment is not disturbed.

In addition, the bottom edge of the housing body is slightly higher than the bottom edge of the second floor extension 22 in the assembled state. Such an assembly method can further ensure the suspended state of the casing. Also, a small part of the structure is removed near the bottom corner of the casing, so that the possibility of deformation of the casing due to collision at the bottom corner is completely avoided by hollowing out the structure.

Mainly refer to FIG. 5 , which shows the connection relationship of the part of the casing near the left side. In this example, the first bottom plate extension portion 21 also has a protruding end 211 near the intersection of the back plate and the casing (the edge on the left side of the casing), and the structure of the protruding end is also roughly trapezoidal but not trapezoidal. The bottom edge is noticeably wider than the right side. Similar to the structure on the right side, the first part 111 of the first casing extension part 11(a) on the left side and the back plate 3 are fixedly connected at the first position on the left side by means of the first screw 71(a). The protruding end 211 of the bottom plate extension and the back plate 3 are fixedly connected by means of the second screw 72(a) at a second position below the first position on the left side, in this example, the second position on the left side and the right side. The first position and the second position roughly correspond in the height direction. At the same time, the second portion 112 abuts against a left side portion of the protruding end 211 .

Adapting to the fact that the bottom edge of the trapezoid at the protruding end is obviously wider than the right side, the widths of the first part and the second part of the first casing extension part 11(a) are also obviously wider than the right side. As in this example, the first portion abuts against the waist region and the upper hem region (in the width direction) of the projecting end.

It can be seen that, in the window machine of the present invention, the assembly of the housing is achieved through a combination of abutment and fixed connection between the casing, the bottom plate and the back plate. Through the connection relationship between the extension part of the first case and the extension part of the second case, on the premise of ensuring the reliability of the connection of the case, compared with the common structure in the market where the case is fully enclosed in the bottom plate, the occurrence of The probability that the casing is deformed or even damaged due to the collision of the casing during transportation and other circumstances. Especially for the bottom corner area of the housing, through the design of the bottom extension part combined with its fixed connection and abutting relationship with the first case extension part, it is possible to effectively avoid the collision of the case at the bottom corner. Possibility, that is, the possibility of shell deformation is completely avoided in the bottom corner area, so the structural stability of the shell of the window machine is improved, and the integrity of the window machine is guaranteed.

It should be noted that although the above specific structure is used as an example for introduction, those skilled in the art can understand that the present invention should not be limited thereto. In fact, those skilled in the art can flexibly adjust related structures according to actual application scenarios and other situations, such as: adjusting the length ratio and width ratio between the first part and the second part, the structural form of the protruding end and the protruding The position of abutment and the area of abutment between the end and the first part; etc.
