For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0036] like Figures 1-7As shown, this utility model provides an outdoor unit, which includes an outdoor unit chassis 100, a heat exchanger 200, a first partition 500, and an expansion tank 520. The heat exchanger 200 is disposed along the edge of the outdoor unit chassis 100, and the first partition 500 is disposed along the width direction of the outdoor unit chassis 100 and connected to the outdoor unit chassis 100. The first partition 500 is disposed near the end of the heat exchanger 200. A receiving groove 510 is provided on the first partition 500, which protrudes from the side of the first partition 500 near the heat exchanger 200 and is offset from the heat exchanger 200.

[0037] One end of the first partition 500 is connected to the outdoor unit chassis 100. The heat exchanger 200 is arranged along the edge of the outdoor unit chassis 100 and located on one side of the first partition 500, so that a receiving space is substantially formed between the heat exchanger 200 and the first partition 500. The receiving groove 510 protrudes from the side of the first partition 500 near the heat exchanger 200, so that the receiving space can be utilized to the maximum extent.

[0038] The misalignment of the receiving tank 510 with the heat exchanger 200 can be either complete or partial. When the receiving tank 510 is completely misaligned with the heat exchanger 200, the tank body of the receiving tank 510 extends along the length of the heat exchanger 200 and is entirely located on the inner side of the heat exchanger 200. When the receiving tank 510 is partially misaligned with the heat exchanger 200, the tank body of the receiving tank 510 extends along the length of the heat exchanger 200, but the orthographic projection portion along the length of the heat exchanger 200 is located at the end of the heat exchanger 200. It is understood that a complete misalignment of the receiving tank 510 with the heat exchanger 200 allows the receiving tank 510 to... The tank can be configured with a larger space, thus enabling the tank to accommodate a larger expansion tank 520 or more expansion tanks 520, such as completely accommodating the expansion tank 520, thereby reducing the encroachment of the expansion tank 520 on the space on the other side of the first partition 500; however, the degree of misalignment between the receiving tank 510 and the heat exchanger 200 depends on the installation position of other devices in the receiving space between the heat exchanger 200 and the first partition 500. Even if the receiving tank 510 is only partially misaligned with the heat exchanger 200, it can still accommodate part of the expansion tank 520, thereby reducing the encroachment of the expansion tank 520 on the space on the other side of the first partition 500.

[0039] The receiving groove 510 is formed by a recess in a portion of the first partition 500 facing the heat exchanger 200.

[0040] The expansion tank 520 can be partially or completely placed in the receiving tank 510, depending on the actual size of the receiving tank 510.

[0041] It is understandable that the outdoor unit provides an expansion tank 520 in the first partition 500 with a receiving groove 510 protruding from one side of the heat exchanger 200. At least part of the expansion tank 520 is placed in the receiving groove 510, and the excess space on one side of the heat exchanger 200 is used to accommodate the expansion tank 520. This reduces the volume occupied by the expansion tank 520 on the other side of the first partition 500 and avoids the expansion tank 520 being completely installed on the side away from the heat exchanger 200, which would affect the disassembly and maintenance of other components.

[0042] In some embodiments, the outdoor unit further includes an outdoor unit side panel 700, which is disposed along the edge of the outdoor unit chassis 100 and connected thereto to form an installation space. The heat exchanger 200 is located on the inner side of the outdoor unit side panel 700 and is disposed along the outdoor unit side panel 700. The side of the first partition 500 near the receiving groove 510 is connected to the outdoor unit side panel 700.

[0043] The outdoor unit side panel 700 is installed along the edge of the outdoor unit chassis 100 and can protect the heat exchanger 200. Generally, the outdoor unit side panel 700 completely covers the heat exchanger 200 along the length and height of the side panel.

[0044] Meanwhile, the outdoor unit side panel 700 is connected to the first partition 500, forming an "L" shape or a similar "U" shape with the first partition 500, so that the two support each other, improve the installation stability of the two, avoid shaking, and thus improve the installation stability of the expansion tank 520.

[0045] In some embodiments, the outdoor unit further includes a second partition 600, which is disposed along and connected to the width direction of the outdoor unit chassis 100. The second partition 600 is disposed on the side of the first partition 500 near the heat exchanger 200 to divide the installation space into a first installation subspace 10, a second installation subspace 20, and a third installation subspace 30. The outdoor unit also includes a fan 300 and a compressor 400. The heat exchanger 200 and the fan 300 are disposed in the first installation subspace 10, and the compressor 400 is disposed in the second installation subspace 20. The groove of the receiving slot 510 is located in the second installation subspace 20.

[0046] One side of the second partition 600 is generally connected to the end of the heat exchanger 200 near the first partition 500, thus dividing the installation space to form a first installation subspace 10 and a second installation subspace 20. The first installation subspace 10 is used to install the fan 300, and the second installation subspace 20 is used to install the compressor 400, thus separating the compressor 400 and the fan 300. At the same time, the first partition 500 separates and forms a third installation subspace 30, which can be used to install devices such as water pumps and electric heaters. Meanwhile, the receiving tank 510 is located in the second installation subspace 20, reducing the encroachment of the expansion tank 520 on the third installation subspace 30.

[0047] In some embodiments, a first folded edge 530 is provided on one side of the first partition 500, and a receiving groove 510 is provided near the first folded edge 530. The outdoor unit also includes a fixing strip 521, one end of which is detachably connected to the first folded edge 530, and the other end of which is detachably connected across the first partition 500 with the connection point located on the side of the receiving groove 510 away from the first folded edge 530. The fixing strip 521 and the receiving groove 510 cooperate to form a fixing space for securing the expansion tank 520 in the receiving groove 510.

[0048] The receiving groove 510 is a groove-shaped structure formed by recessing from one side of the first partition 500. The receiving groove 510 has an annular sidewall and a bottom wall connected to the annular sidewall, so that after the expansion tank 520 is placed in the receiving groove 510, the sidewall of the receiving groove 510 can support the expansion tank 520. At the same time, one end of the fixing strip 521 is connected to the first folded edge 530, and the other end is connected to the first partition 500 and located on the side of the receiving groove 510 away from the first folded edge 530. The fixing strip 521 can clamp the expansion tank 520 in the receiving groove 510.

[0049] The first partition 500 and the first folded edge 530 have an included angle, which is generally greater than 0° and less than or equal to 90°, so that one end of the fixing strip 521 can be connected to the first folded edge 530. It is understood that the first folded edge 530 is set on one side of the first partition 500, and one end of the fixing strip 521 is connected to the first partition 500 and the other end is connected to the first folded edge 530. Since the first folded edge 530 is located on the outermost side of the first partition 500, it is convenient to separate the solid strip from the first folded edge 530, so as to release the clamping effect of the solid strip on the first partition 500 and remove the expansion tank 520 from the first partition 500.

[0050] In general, the first partition 500 is provided with folded edges on all four sides, that is, the first partition 500 is provided with folded edges on both sides and both ends; however, in order to place the expansion tank 520 and facilitate the connection of the fixing strip 521, the side edge of the first partition 500 near the receiving groove 510 is provided, and the folded edge closest to the receiving groove 510 on both sides is defined as the first folded edge 530.

[0051] The detachable connection between the fixing strip 521 and the first folded edge 530 and the first partition 500 can be one or more of the following connection methods: screw connection, snap-on connection, hanging connection, etc.

[0052] The receiving groove 510 can be configured to completely contain the expansion tank 520, for example, the expansion tank 520 can be completely placed in the receiving groove 510; or it can be configured to partially contain the expansion tank 520, that is, part of the expansion tank 520 is contained in the receiving groove 510 and part of it is exposed outside the receiving groove 510. When part of the expansion tank 520 is exposed outside the receiving groove 510, the fixing strip 521 can adopt a "U" shaped structure to cooperate with the receiving groove 510 to form a fixed space.

[0053] It is understandable that the outdoor unit has a first folded edge 530 and a receiving groove 510 on the first partition 500, and the receiving groove 510 is set close to the first folded edge 530. At the same time, one end of the fixing strip 521 is detachably connected to the first folded edge 530 and the other end is detachably connected to the first partition 500. Together with the receiving groove 510, a fixed space is formed to lock the expansion tank 520. Thus, the expansion tank 520 can be quickly disassembled by releasing the connection between the fixing strip 521 and the first folded edge 530.

[0054] In some embodiments, the outdoor unit includes at least two fixing bars 521, which are spaced apart from each other along the height direction of the expansion tank 520.

[0055] Among them, multiple solid strips are distributed at intervals along the height direction of the expansion tank 520, which can cooperate with the receiving groove 510 at various height positions of the expansion tank 520 to improve the fixation stability of the expansion tank 520 by the fixed space.

[0056] Specifically, the outdoor unit includes two fixing bars 521, which are spaced apart from each other along the height direction of the expansion tank 520. Each fixing bar 521 is set close to the expansion tank 520 to secure the expansion tank 520 in a fixed space.

[0057] In some embodiments, one end of the fixing strip 521 is connected to the first partition 500 by a snap fastener, and the other end of the fixing strip 521 is connected to the first folded edge 530 by a screw.

[0058] It is understandable that screw connections can improve connection stability, while snap-fit ​​connections can simplify disassembly steps and improve disassembly efficiency.

[0059] Therefore, the first folded edge 530 is located on the outside of the first partition 500. Compared with setting the screw connection end of the fixing strip 521 on the first partition 500, setting it on the first folded edge 530 makes it easier to disassemble. At the same time, in order to reduce the difficulty of disassembly, the other end of the fixing strip 521 is snapped to the first partition 500. After the screw connection between the fixing strip 521 and the first folded edge 530 is released, the snap connection between the fixing strip 521 and the first partition 500 can be easily released, and then the fixing strip 521 can be removed.

[0060] In this embodiment, the fixing strip 521 is connected by a screw at one end and by a snap-fit ​​at the other end. The purpose is to balance disassembly efficiency and connection stability. Setting the screw connection on the first folded edge 530 makes it easier to operate than setting it on the partition.

[0061] In other embodiments, the connection between the fixing strip 521 and the first folded edge 530 can also be a snap-fit ​​connection, and the connection between the fixing strip 521 and the partition can also be a screw connection.

[0062] In some embodiments, the first folded edge 530 is perpendicular to the first partition 500. That is, the angle between the first partition 500 and the first folded edge 530 is 90°.

[0063] Understandably, by making the first folded edge 530 perpendicular to the first partition 500, the two ends of the fixing strip 521 are connected on different mounting planes, thereby restricting the movement of the expansion tank 520 from at least two directions and firmly securing the expansion tank 520 in the fixed space. Simultaneously, setting the first folded edge 530 perpendicular to the first partition 500 facilitates the disassembly of the fixing strip 521 and the first folded edge 530.

[0064] In some embodiments, the shape and size of the receiving groove 510 are the same as those of the expansion tank 520.

[0065] That is, by setting the shape and size of the receiving groove 510 to be the same as the shape and size of the expansion tank 520, the expansion tank 520 can be completely placed into the receiving groove 510, which can further protect the expansion tank 520.

[0066] Participate in the attached Figure 6 S1 is the length direction of expansion tank 520, S2 is the thickness direction of expansion tank 520, and S3 is the width direction of expansion tank 520.

[0067] See appendix Figure 7S4 is the height direction of the receiving groove 510, S5 is the width direction of the receiving groove 510, and S6 is the depth direction of the receiving groove 510.

[0068] Specifically, the depth of the receiving groove 510 is the same as the width of the expansion tank 520, the width of the receiving groove 510 is the same as the thickness of the expansion tank 520, and the height of the receiving groove 510 is the same as the length of the expansion tank 520; that is, the expansion tank 520 can be completely placed into the receiving groove 510 along its width direction.

[0069] Specifically, the depth of the receiving groove 510 is the same as the thickness of the expansion tank 520, the width of the receiving groove 510 is the same as the width of the expansion tank 520, and the height of the receiving groove 510 is the same as the length of the expansion tank 520; that is, the expansion tank 520 can be completely placed into the receiving groove 510 along its thickness direction.

[0070] Specifically, the depth of the receiving groove 510 is the same as the length of the expansion tank 520, the width of the receiving groove 510 is the same as the thickness of the expansion tank 520, and the height of the receiving groove 510 is the same as the width of the expansion tank 520; that is, the expansion tank 520 can be completely placed into the receiving groove 510 along its length.

[0071] In this process, after the expansion tank 520 is fully placed into the receiving groove 510, the solid strip part at least abuts against the expansion tank 520 to achieve the locking of the expansion tank 520.

[0072] In some embodiments, a first support protrusion is provided on one side of the receiving groove 510, and a second support protrusion is provided on the other side of the receiving groove 510. The first support protrusion and the second support protrusion are arranged opposite to each other to form a clamping structure for clamping the expansion tank 520.

[0073] The interval between the first support protrusion and the second support protrusion is exactly the same as or slightly smaller than the width of the portion of the expansion tank 520 inserted into the receiving groove 510, so that the clamping structure and the expansion tank 520 are in an interference fit, thereby clamping the expansion tank 520 and improving the installation stability of the expansion tank 520.

[0074] In some embodiments, the present invention also provides an air conditioner that includes the outdoor unit described above. Since the air conditioner includes the outdoor unit described above, that is, includes some or all of the embodiments of the outdoor unit described above, the air conditioner has the beneficial effects of some or all of the embodiments of the outdoor unit described above, which will not be described in detail here.

[0075] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
