Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an outdoor unit chassis, an outdoor unit, and an air conditioner. Background Technology

[0002] Split air conditioners generally consist of two parts: an outdoor unit and an indoor unit. The outdoor unit typically includes an outdoor heat exchanger, a fan, a compressor, and a chassis that supports the outdoor heat exchanger, compressor, and fan. The drainage performance of the chassis is one of the key factors affecting the operating efficiency and reliability of the air conditioner. However, existing chassis are generally only suitable for one type of heat exchanger (such as L-type heat exchangers or C-type heat exchangers). When a chassis adapted for an L-type heat exchanger is used to support a C-type heat exchanger, its drainage performance will be significantly reduced. Therefore, there is a lack of a chassis in the current technology that can adapt to different types of heat exchangers. Utility Model Content

[0003] The main objective of this utility model embodiment is to provide an outdoor unit chassis and air conditioner, aiming to improve the technical problem that the chassis in the prior art cannot be adapted to heat exchangers of different structural types.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] 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.

[0029] like Figures 1-4 As shown, this utility model provides an outdoor unit chassis 10, which includes a chassis body 100, a first guide channel 110, and a second guide channel 120. The first guide channel 110 is L-shaped, and a first drain hole 130 is provided on the bottom wall of the first guide channel 110 for draining condensate from the first guide channel 110 into the chassis body 100. The second guide channel 120 is I-shaped, and the first guide channel 110 and the second guide channel 120 are connected, forming a C-shaped guide channel.

[0030] The fact that the first guide channel 110 is "L" shaped does not mean that the first guide channel 110 only has an "L" shaped structure. Rather, it has other configurations in addition to having an "L" shaped structure. For example, the first guide channel 110 can be "T" shaped, and its horizontal "T" shaped first guide channel 110 has an "L" shaped structure.

[0031] The bottom wall of the second guide channel 120 is slightly higher than the bottom wall of the first guide channel 110, so that the condensate in the second guide channel 120 can flow into the first guide channel 110 and be discharged from the outdoor unit chassis 10 through the first drain hole 130.

[0032] It is understandable that the outdoor unit chassis 10 is equipped with an "L"-shaped first guide channel 110 and an "I"-shaped second guide channel 120. By connecting the first guide channel 110 and the second guide channel 120, the two can be matched to form a "C"-shaped guide channel. That is, when installing an L-shaped heat exchanger 20, it can be adapted by the first guide channel 110. When installing a C-shaped guide channel, it can be adapted by the first guide channel 110 and the second guide channel 120. Thus, the outdoor unit chassis 10 can be adapted to two different structural types of heat exchangers 20.

[0033] In some embodiments, the bottom wall between the end of the first guide channel 110 and the first drain hole 130 is a first bottom wall. The first bottom wall is inclined, with one end of the first bottom wall near the first drain hole 130 located near the ground side of the chassis body 100, and the other end of the first bottom wall away from the first drain hole 130 located near the far side of the chassis body 100.

[0034] Among them, the far-ground side of the chassis body 100 is the side of the chassis body 100 that is far away from the ground. Generally, the point where the chassis body 100 is farthest from the ground is taken as the far-ground base point; the near-ground side of the chassis body 100 is the side of the chassis body 100 that is close to the ground. Generally, the point where the chassis body 100 is closest to the ground is taken as the near-ground base point.

[0035] The first guide channel 110 has a first bottom wall between its two ends and the first drain hole 130.

[0036] It is understandable that the first bottom wall is inclined, and the end of the first bottom wall near the first drain hole 130 is set closer to the ground, while the end away from the first drain hole 130 is set closer to the far ground. That is, the height of the first bottom wall gradually decreases from the end away from the first drain hole 130 to the first drain hole 130, so that the condensate can flow smoothly into the first drain hole 130.

[0037] In some embodiments, the bottom wall of the second guide channel 120 is inclined, and the end of the bottom wall of the second guide channel 120 connected to the first guide channel 110 is located near the ground side of the chassis body 100, while the end of the bottom wall of the second guide channel 120 away from the first guide channel 110 is located near the far ground side of the chassis body 100.

[0038] It is understandable that the bottom wall of the second guide channel 120 is inclined, and the end connected to the first guide channel 110 is located near the ground, that is, the height of the end of the second guide channel 120 connected to the first guide channel 110 is lower; the end of the second guide channel 120 away from the first guide channel 110 is located near the far ground, that is, the height of the end of the second guide channel 120 away from the first guide channel 110 is higher. The height of the bottom wall of the entire second guide channel 120 gradually decreases from the end away from the first guide channel 110 to the end connected to the first guide channel 110, so that the condensate in the second guide channel 120 can flow smoothly into the first guide channel 110.

[0039] In some embodiments, the bottom wall of the second guide channel 120 is slightly higher than the bottom wall of the first guide channel 110 near the second guide channel 120, so that the condensate in the second guide channel 120 can flow smoothly into the first guide channel 110.

[0040] In some embodiments, the first guide channel 110 includes a main flow sub-channel 111 and a secondary flow sub-channel 112 connected in sequence. The main flow sub-channel 111 is arranged along the length direction of the chassis body 100, and a first drain hole 130 is provided in the main flow sub-channel 111. The secondary flow sub-channel 112 is arranged along the width direction of the chassis body 100. The second guide channel 120 is connected to the end of the main flow sub-channel 111 away from the secondary flow sub-channel 112.

[0041] In some embodiments, the first guide channel 110 has a plurality of auxiliary guide channels in addition to the main guide channel 111 and the secondary guide channel 112. The other auxiliary guide channels may be connected to the main guide channel 111 or to the secondary guide channel 112.

[0042] In some embodiments, a plurality of second drainage holes 140 are also provided on the bottom wall of the first guide channel 110, and the plurality of second drainage holes 140 are spaced apart from each other and from the first drainage hole 130.

[0043] It is understandable that setting multiple second drain holes 140 in conjunction with the first drain hole 130 for drainage can improve the drainage efficiency of the chassis body 100 and also prevent drainage failure when a single drain hole is blocked.

[0044] In some embodiments, the chassis body 100 is further provided with a plurality of auxiliary guide channels 160, which are respectively connected to the first guide channel 110. Specifically, the plurality of auxiliary guide channels 160 include a first auxiliary guide channel, a second auxiliary guide channel, and a third auxiliary guide channel. The first auxiliary guide channel, the second auxiliary guide channel, and the third guide channel are disposed on both sides of the first guide channel 110, and the first auxiliary guide channel, the second auxiliary guide channel, and the third guide channel are respectively connected to the first guide channel 110.

[0045] Understandably, adding an auxiliary guide channel 160 can increase the water contact area of ​​the chassis body 100.

[0046] In some embodiments, the chassis body 100 is further provided with a plurality of auxiliary guide channels 160, which are sequentially connected and then connected to the first guide channel 110. Specifically, the plurality of auxiliary guide channels 160 include a first auxiliary guide channel, a second auxiliary guide channel, and a third auxiliary guide channel. The first guide channel 110, the second guide channel 120, and the third guide channel are sequentially connected, and the end of the third guide channel away from the second guide channel 120 is connected to the first guide channel 110.

[0047] In some embodiments, a plurality of heat exchanger support platforms are provided on the chassis body 100, and the plurality of heat exchanger support platforms are distributed at intervals along the length direction of the first guide channel 110 and the second guide channel 120. That is, the plurality of heat exchanger support platforms are distributed on both sides of the first guide channel 110 and the second guide channel 120 to facilitate the chassis body 100 in fixing the heat exchanger 20.

[0048] In some embodiments, an outdoor unit is also provided, which includes the outdoor unit chassis 10 described above. Since the outdoor unit includes some or all of the embodiments of the outdoor unit chassis 10 described above, the outdoor unit has the beneficial effects of some or all of the embodiments described above, which will not be described in detail here.

[0049] 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, that is, it includes some or all of the embodiments of the outdoor unit chassis 10, the air conditioner has the beneficial effects of some or all of the embodiments of the outdoor unit chassis 10, which will not be described in detail here.

[0050] 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.
