[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0041] Rooftop unit in the prior art ( Figure 1 ), a cover plate with an air outlet is set at the top, the condenser is surrounded by the side of the roof machine shell in a "J" shape, and the corresponding side is provided with an air inlet, the space enclosed by the condenser is the condenser cavity, the compressor, gas-liquid separator, oil separator, four-way valve and other pipeline components are directly arranged inside the condensation cavity, and rainwater can directly fall on the various pipeline components in the condenser cavity through the air outlet on the upper part of the condensation fan, and the compressor and other components have high requirements for waterproof level, and the sound insulation blanket is not easy to dry after being wet, and the compressor base is easily corroded in a long-term humid state. In this regard, the utility model proposes an air-conditioning shell structure, which divides the original condenser cavity in the air-conditioning shell, and sets a partition assembly at a corner of the rectangular shell. The space enclosed by the inner side of the partition assembly and the condenser is the condenser cavity, which can also be called the fan cavity installation fan assembly, and the space enclosed between the outer side of the partition assembly and the outer wall of the shell and the end face of the condenser is the compressor cavity, where the compressor and its pipeline assembly are installed, and the partition assembly can block rainwater to prevent rainwater from entering the compressor cavity, so as to avoid the compressor cavity being in a humid state and corroding the internal parts. It can also reduce the transmission of compressor noise.

[0042] like Figures 2 to 4 As shown in Figure 8, the air-conditioning shell structure proposed by the utility model includes: a shell 7 and a partition assembly 1. The shell 7 is a rectangular frame structure, the top surface of which is provided with a top plate for closure, and a circular air outlet 72 is provided in the middle. The heat exchanger 2 is arranged around multiple sides of the shell, that is, multiple sides serve as air inlet surfaces, and a fan assembly is installed below the shell air outlet 72 in the surrounding area of ​​the heat exchanger. The fan assembly introduces wind from the side of the shell to exchange heat through the heat exchanger, and blows it out from the air outlet 72 on the top surface of the shell. A vertical partition assembly is arranged at the corresponding corner in the shell, and the corner of the shell is separated from the fan cavity where the fan assembly is installed as a compressor cavity, that is, the outer side of the partition assembly 1 is the compressor cavity, and the inner side of the partition assembly 1 is the condenser cavity of the fan, or the fan cavity.

[0043] By setting a partition assembly in the shell for separation, the compressor and other components are separated from the original condenser cavity, and do not directly correspond to the air inlet on the top of the shell, so as to prevent rainwater from entering the installation area of ​​the compressor, oil separator, pipeline and other components from the air inlet on the top of the shell, thereby preventing the compressor and other components from being in a wet state and easily corroded, thereby improving the service life of the components and the stability of the air-conditioning unit.

[0044] like Figure 4 , 5 As shown in Figures 6 and 7, in the first embodiment, the partition assembly 1 is divided into two layers along the height direction. The upper layer corresponds to the fan bracket arranged in the fan cavity, which is bent to make way and shrink toward the direction of the compressor cavity. It is mainly used to install pipelines and other components that can be extended longitudinally. There is no fan bracket at the position of the lower layer, so it is directly enclosed in a rectangle that arches into the fan cavity, which is convenient for the installation of the compressor and the oil separator.

[0045] like Fig. 9 , 10 As shown, in the second embodiment, the partition assembly 1 includes a plurality of vertical plates spliced ​​vertically, and the fan support in the fan cavity is recessed inwardly toward the compressor cavity (without upper and lower stratification), and the gas-liquid separator and the compressor 4 in the compressor cavity are staggered in the height direction in the compressor cavity, wherein the compressor 4 is directly installed at the bottom of the compressor cavity, and the gas-liquid separator is a wall-mounted gas-liquid separator directly installed on the vertical plate of the partition assembly, and the piping systems are bent and extended upward or downward to adapt to the contour of the compressor cavity, so that the space arrangement in the shell is compact.

[0046] In the above two embodiments, a connecting edge is provided on the lower edge of the partition assembly 1, which is connected to the bottom plate 71 located at the bottom surface of the compressor chamber in the shell. The vertical side edge on one side of the partition assembly 1 is connected to the side plate of the end surface of the condenser, and the vertical side edge on the other side is connected to a column vertically arranged on the side of the shell for fixing the electrical box.

[0047] By directly connecting the partition assembly to the end face of the condenser, the number of vertical brackets is reduced, and the vertical bracket connected to one vertical side also serves as a fixed bracket for the electrical box, thereby simplifying the overall structure and facilitating installation and disassembly.

[0048] like Figure 5 , 6 As shown in Figures 7, in the first embodiment, the partition assembly specifically includes: a lower partition 12 located at the lower layer, an upper partition 11 located at the upper layer, and a cover plate 13 connected to the gap formed when the upper partition 11 gives way, and the cover plate 13 connects the upper partition 11 and the lower partition 12.

[0049] The lower partition 12 specifically includes: a first lower partition and a second lower partition bent at a right angle. The vertical side of the first lower partition is provided with a connecting edge, which is connected to the side plate set on the end face of the heat exchanger by screws. The vertical side of the second lower partition is vertically bent into the fan cavity. A gap is left between the vertical side of the second lower partition and the vertical of the shell to facilitate wiring of the electrical box or installation of pipelines, etc.

[0050] The upper partition 11 specifically includes: 6 upper vertical partitions of different widths are bent, and the 6 upper vertical partitions are connected in sequence. The contour formed by the bending corresponds to the fan bracket to make way, so that the upper space of the compressor cavity is smaller than the lower space. The upper vertical partition located on the far left is provided with a connecting edge, which is connected to the connecting edge provided on the end face of the heat exchanger by screws, and the upper vertical partition located on the far right is also provided with a connecting edge fixedly connected to the vertical bracket.

[0051] A cover plate 13 is installed in the gap formed after the upper partition 11 gives way. The upper partition 11 is located at the bottom of the three middle upper vertical partitions and is bent outward (toward the fan chamber) to form a connecting edge, which is connected to the edge of the cover plate by screws. The lower partition 12 corresponds to the upper edge of the cover plate 13 and is provided with a connecting edge bent inward (toward the compressor) to form a connecting edge, which is connected to the edge of the cover plate by screws, so that the cover plate 13 closes the gap formed after the upper partition gives way.

[0052] like Figure 2 , 8 As shown, the left side, rear side, and part of the right side of the upper part of the shell are surrounded by the heat exchanger 2, that is, the left side, rear side, and part of the right side are used as air inlet surfaces, and the front side of the upper part of the shell and another part of the right side close to the front side are covered by an inspection plate, so as to facilitate the inspection of the parts of the shell.

[0053] The inspection panel specifically includes: a first inspection panel 51 and a second inspection panel 52. The first inspection panel 51 is installed on the upper part of the front side of the shell 7 to cover the electrical box 3 on the left side of the front side of the shell 7. At the same time, the right side of the first inspection panel 51 and the second inspection panel 52 are spliced ​​at right angles to form a compressor cavity together with the vertically arranged partition assembly 1. When it is necessary to inspect the components in the air conditioner, the first and second inspection panels can be directly removed to fully expose the components in the electrical box 3 and the compressor cavity, which is convenient for operators to perform inspection operations and is more convenient for early installation.

[0054] It should be noted that the folded edges or side edges used for connection of the panels are provided with screw holes, or snaps are used for fixed connection. Since this is a common method of fixing panels in the prior art, it will not be described in detail.

[0055] The utility model also provides an air conditioner, comprising the above-mentioned air conditioner housing structure.

[0056] In a specific embodiment, the air conditioner is a rooftop air conditioner, that is, the inner and outer units are integrated.

[0057] The air conditioner specifically comprises: a fan assembly, a compressor assembly and a heat exchanger. The fan assembly is arranged in the fan cavity, the compressor assembly is installed in the compressor cavity, and the heat exchanger is arranged around the side of the shell.

[0058] The fan assembly specifically includes a fan and a fan bracket. The upper layer of the partition assembly is located at the side edge of the fan bracket. The heat exchanger is a condenser, which is arranged in a "J" shape and surrounded by multiple sides of the shell, so that the multiple sides of the shell serve as the air inlet side to exchange heat with the condenser.

[0059] The compressor assembly specifically includes: a compressor 4 , a plate heat exchanger assembly 101 , a gas-liquid separator 102 , a four-way valve assembly 104 , an air intake pipe assembly 105 , a heating electronic expansion valve assembly 106 and a cooling electronic expansion valve assembly 107 .

[0061] 1. First, fix the lower partition 12 to the shell 7;

[0062] 2. Then fix the plate heat exchanger assembly 101 on the side of the lower partition 12 facing the compressor compartment;
