DETAILED DESCRIPTION

[0032] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0033] like Figures 1 to 11 As shown, an exemplary embodiment of the present disclosure provides a housing assembly, which is optionally applicable to an air conditioner outdoor unit, and further optionally applicable to a multi-split air conditioner outdoor unit. Specifically, the housing assembly provided by the present disclosure includes a first front panel 2 for covering a fan chamber 100, a first side panel 6 adjacent to the first front panel 2, and a heat exchanger end plate 310 connected to a heat exchanger 300. The first front panel 2 is fixedly connected to the heat exchanger end plate 310, and the first side panel 6 covers the connection between the first front panel 2 and the heat exchanger end plate 310. The first side panel 6 is pluggable with the first front panel 2.

[0034] It should be noted that the up, down, left, right, front and back here are based on the direction in which a person is facing the air-conditioning outdoor unit when the outdoor unit is installed and in use. The shell assembly usually encloses a relatively closed space to accommodate internal components. Taking into account the harsh working environment of the fan, which will cause adverse interference to components such as the compressor and electronic control, the internal space of the shell assembly is usually divided into two independent chambers. Taking a large multi-split air-conditioning outdoor unit as an example, its internal space can be divided into a fan chamber 100 and a compressor chamber 200 by, for example, a middle partition 5, wherein the fan chamber 100 is used to accommodate components such as the fan and the heat exchanger 300, and the compressor chamber 200 is used to accommodate components such as the compressor and the electronic control device.

[0035] The housing assembly of an air conditioner outdoor unit is typically composed of multiple panels. For example, a multi-split air conditioner outdoor unit typically includes a first front panel 2 and a second front panel 3, a rear panel positioned opposite the front panels, first and second side panels 6 and 4, and a top cover 1 and bottom panel 8. It should be noted that, unless otherwise specified, in the following description, the first front panel 2 refers to the large panel covering the fan cavity 100, and the first side panel refers to the left panel adjacent to the large panel.

[0036] In the related art, bolts are usually used to fix the panels together. On the one hand, this method has low assembly efficiency, and on the other hand, the exposed bolts are not neat and beautiful. Based on this technical problem, the shell assembly provided by the present disclosure no longer uses bolts to connect the first front panel 2 and the first side panel 6, but uses slots and buckles for plug-in connection. Considering the reliability of the installation of the first front panel 2, the present disclosure bolts the first front panel 2 to the heat exchanger end plate 310. The heat exchanger end plate 310 can be a component independent of the heat exchanger 300, which is provided with a plurality of holes for the gas branch pipes to pass through in the up and down directions and is connected to the heat exchanger end plate 310 through the expansion effect of the gas branch pipes.

[0037] At this time, although the first front panel 2 and the heat exchanger end plate 310 are connected by bolts, the connection between the two can be further blocked by the first side panel 6, so that no bolts are exposed in appearance. At the same time, the first side panel 6 and the first front panel 2 are plug-in compatible. For example, a first slot 222 can be provided on the first front panel 2, and a first buckle 61 can be provided on the first side panel 6, and the plug-in structure of the first front panel 2 and the first side panel 6 can be hidden on the inner side of the first side panel 6. In this way, there are no exposed bolts connecting the first front panel 2 and the heat exchanger end plate 310, and no exposed bolts connecting the first front panel 2 and the first side panel 6. As a whole, the first front panel 2 can be installed on the side without exposed bolts, and the shape of the whole machine is more neat and beautiful. In addition, the first front panel 2 is assembled with the help of the heat exchanger end plate 310 of the air conditioner outdoor unit. On the one hand, the heat exchanger end plate 310 is closer to the first side panel 6, which makes the connection more convenient. On the other hand, it is assembled directly with the help of the original components of the air conditioner outdoor unit, which saves the process of setting up additional parts and saves the internal space of the air conditioner outdoor unit.

[0038] In order to facilitate the installation of the first front panel 2 and the heat exchanger end plate 310, in some embodiments, as shown in FIG. Figure 3 and Figure 5As shown, the first front panel 2 includes a first flange 22 that is bent toward the first side panel 6. The first flange 22 is provided with a first mounting hole 221 for connecting to the heat exchanger end plate 310. It should be noted that the first flange 22 can be formed by bending from the side of the first front panel 2 or can be integrally molded during injection molding. The first flange 22 extends in the vertical direction and its length can be roughly the same as or slightly shorter than the length of the heat exchanger end plate 310. The first flange 22 can be provided with multiple first mounting holes 221 at intervals along the vertical direction.

[0039] In other embodiments, to achieve plug-in fit between the first side panel 6 and the first front panel 2, as shown in FIG. Figure 4 He Ru Figure 5 As shown, the first side panel 6 can be provided with a first snap 61, and the first front panel 2 is provided with a first slot 222 that plugs and cooperates with the first snap 61. In this way, after the first side panel 6 is installed, the first snap 61 can be hidden inside the first side panel 6. Furthermore, the first slot 222 can be a strip extending in the up-down direction, and the first snap 61 is provided with a first slot portion 611 opening downward. The first slot portion 611 can be plugged and cooperated with the lower end of the first slot 222, which enables the first snap 61 to be hooked on the lower end of the first slot 222, thereby improving the reliability of the connection between the first side panel 6 and the first front panel 2.

[0040] By any of the above embodiments, the first front panel 2 can be installed on the left side without exposed bolts. The following will exemplarily introduce the installation method of the first front panel 2 at other positions without exposed bolts with reference to the accompanying drawings.

[0041] For the installation of the bottom of the first front panel 2, as Figure 3 and Figure 5 As shown, the shell assembly can also include a base plate 8, the side of the base plate 8 is provided with a second flange 81 bent upward, and the bottom of the first front panel 2 is provided with a second slot portion 223 opening downward, and the second slot portion 223 can be plugged into and matched with the second flange 81 to limit the left and right movement of the first front panel 2.

[0042] For the installation on the top of the first front panel 2, as Figure 3 and Figure 6As shown, the top of the first front panel 2 may be provided with a third flange 23 that bends toward the rear side of the housing assembly. The housing assembly may further include a motor bracket 9, which may be provided with a plurality of upwardly extending limiting teeth 91. The limiting teeth 91 may be, for example, rib-shaped. The third flange 23 at least partially covers the motor bracket 9 and is provided with limiting holes 231 that cooperate with the limiting teeth 91 to limit lateral movement of the first front panel 2. Lateral movement here includes movement in the front-back, left-right, and right directions. Multiple limiting teeth 91 may be provided at intervals along the left-right direction.

[0043] Further, if Figure 7 As shown, the motor bracket 9 can be provided with a fourth flange 92 bent upward, and the fourth flange 92 at least partially extends into the space between the plate surface of the first front panel 2 and the third flange 23. The third flange 23 is provided with a third mounting hole 232, and the first front panel 2 and the first side panel 6 are fixed by bolts that pass through the third flange 23 and the fourth flange 92 in sequence from the inside to the outside of the shell assembly.

[0044] For the installation on the right side of the first front panel 2, as Figure 8 As shown, the shell assembly provided by the present disclosure may also include a middle partition 5, which is used to separate the internal space of the shell assembly into a fan chamber 100 and a compressor chamber 200. The first front panel 2 and the middle partition 5 are fixedly connected by bolts, and the second front panel 3 covers the connection between the first front panel 2 and the middle partition 5, and is plugged into the first front panel 2. Similar to the way the first front panel 2 is installed on the left side, although the first front panel 2 and the middle partition 5 are fixedly connected by bolts, the connection between the two can be further blocked by the second front panel 3, so that no bolts are exposed in appearance. At the same time, the second front panel 3 and the first front panel 2 are plugged into each other, and the plug-in structure of the second front panel 3 and the first front panel 2 can be hidden on the inner side of the second front panel 3.

[0045] In some embodiments, as Figure 9As shown, the middle partition 5 includes a slot structure 51 opening toward the fan cavity 100. The slot structure 51 includes a first rib 511 bent from the front end of the middle partition 5 toward the compressor cavity 200, a connecting edge 512 bent toward the front side of the housing assembly, and a second rib 513 bent from the connecting edge 512 toward the fan cavity 100. The second rib 513 is provided with a second mounting hole 514 for removably engaging with the first front panel 2. The opening of the first slot structure 51 faces the fan cavity 100, thereby isolating rainwater from the compressor cavity 200 and directing rainwater into the fan cavity 100, which has relatively low waterproofing requirements. From a cross-sectional perspective, the slot structure 51 can be constructed in a C-shape, with the enclosed space serving as a channel, opening toward one side of the fan cavity 100. The first rib 511 and the first connecting edge 512 serve to isolate the compressor cavity 200, and the second rib 513 is used to connect to the first front panel 2. The first groove structure 51 having multiple ribs can be formed by bending the center partition plate 5 multiple times.

[0046] In order to facilitate the installation of the first front panel 2 and the middle partition 5, in some embodiments, such as Figure 10 and Figure 11 As shown, a fifth flange 21 is provided on the side of the first front panel 2 close to the compressor cavity 200 , the fifth flange 21 is provided with a second card slot 211 , and the second front panel 3 is provided with a second buckle that is plugged into the second card slot 211 .

[0047] Taking into account that there may be a gap between the second slot 211 and the second buckle in the plug-in form, in order to prevent rainwater from entering the compressor chamber 200 through the gap, the present disclosure can make the second slot 211 constructed to be connected to the slot structure 51, so that even if some rainwater enters through the gap, it can be guided to the first slot structure 51, and then guided into the fan chamber 100, thereby improving the safety performance of the air conditioner outdoor unit.

[0048] According to the second aspect of the embodiment of the present disclosure, there is also provided an air-lifting external machine, comprising any one of the above-mentioned shell components and having all the beneficial effects thereof, which will not be described in detail here.

[0049] In the foregoing detailed description, reference is made to the accompanying drawings, which illustrate, by way of illustration, specific aspects of the present disclosure in which it may be practiced. In this regard, terms indicating directions or expressing positional relationships, such as "center," "longitudinal," "lateral," "length," "width," "thickness," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "clockwise," "counterclockwise," "axial," "radial," "circumferential," etc., may be used with reference to the orientation of the figures being described. Since the components of the described devices may be positioned in a plurality of different orientations, the directional terms may be used for illustrative purposes rather than restrictive. It should be understood that other aspects may be utilized and structural or logical changes may be made without departing from the concepts of the present disclosure. Therefore, the following detailed description should not be taken in a limiting sense.

[0050] It should be understood that, unless otherwise specifically noted, the features of the various embodiments of the present disclosure described herein may be combined with each other. As used herein, the term "and / or" includes any one of the relevant listed items and any combination of any two or more thereof; similarly, "at least one of" includes any one of the relevant listed items and any combination of any two or more thereof.

[0051] It should be understood that, unless otherwise expressly specified or limited, the terms "join," "attach," "install," "connect," "connect," "fix," etc. used in the embodiments of the present disclosure should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrated; they can be mechanically connected, electrically connected, or communicable with each other; they can be directly connected, or indirectly connected through an intermediate medium, and they can be internally connected between two elements or an interactive relationship between two elements, unless otherwise expressly limited. For those skilled in the art, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0052] Additionally, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may be used herein to mean that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are disposed between the surface and the component, element, or material layer. However, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may alternatively have a specific meaning: the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, e.g., in direct contact with the surface.

[0053] Although terms such as "first", "second" and "third" may be used herein to describe various components, parts, regions, layers or sections, these components, parts, regions, layers or sections are not limited to these terms. On the contrary, these terms are only used to distinguish one component, part, region, layer or section from another component, part, region, layer or section. Therefore, without departing from the teachings of each example, the first component, part, region, layer or section mentioned in the examples described herein may also be referred to as the second component, part, region, layer or section. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one such feature. In the description herein, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0054] It should be understood that spatially relative terms, such as "above," "upper," "below," and "lower," are used herein to describe the relationship of one element to another element shown in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as being "above" or "upper" relative to another element would then be "below" or "lower" relative to the other element. Thus, the term "above" encompasses both above and below orientations, depending on the spatial orientation of the device. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.

[0055] Furthermore, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous over other aspects or designs. Rather, the use of the word exemplary is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies to A or B" is intended to mean any of the natural inclusive permutations. That is, if X applies to A; X applies to B; or X applies to both A and B, then "X applies to A or B" satisfies any of the aforementioned instances. Furthermore, the articles "a" and "an," as used in this application and the appended claims, are generally understood to mean "one or more," unless otherwise specified or clear from the context to refer to the singular form.

[0056] Likewise, although the present disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. The present disclosure includes all such modifications and variations and is limited only by the scope of the claims.

In addition, although particular features of the present disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations as may be desired and advantageous for any given or particular application. Furthermore, to the extent that the terms "include," "have," "have," "have," or variations thereof are used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term "comprising."

[0057] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein.
