DETAILED DESCRIPTION

[0030] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0031] In the present disclosure, unless otherwise stated, directional words such as "up, down, front, back, left, right" are used based on Figure 1The XYZ coordinates in the figure are defined, specifically, the X direction refers to the front-to-back direction, and the side indicated by the arrow is the front, and the opposite is the back; the Y direction refers to the left-to-right direction; the Z direction refers to the up-down direction, and the side indicated by the arrow is the top, and the opposite is the bottom, wherein the top corresponds to the top, and the bottom corresponds to the bottom. In addition, the up-down direction can also refer to the gravity direction of the rear frame. "Inside and outside" refer to the inside and outside of the contours of each component itself. The terms "first" and "second" are used to distinguish one element from another, and do not have order and importance. In addition, when the following description refers to the drawings, the same figure marks in different drawings represent the same or similar elements, and the present disclosure will not elaborate on this.

[0032] According to some embodiments of the present disclosure, a rear frame is provided, referring to Figure 1 and Figure 2 As shown in the figure, the rear frame includes a rear frame body 1 and a guide structure 2, the rear frame body 1 has an inner wall 11 and a front wall 12, the guide structure 2 includes a first water receiving plate 21 and a drainage structure 22, the first water receiving plate 21 is connected to the inner wall 11, and is connected to the front wall 12, the drainage structure 22 is arranged on the front wall 12, and is used to guide the condensation water flowing out through the first water receiving plate 21 to flow downward, and the part of the rear frame body 1 located at the lower side of the drainage structure 22 is used to set the water receiving tray 10.

[0033] Through the above technical scheme, in the rear frame provided by the present invention, since the inner wall 11 of the rear frame body 1 is close to the evaporator 20, hot and cold convection is likely to occur at the inner wall 11, and condensation water is likely to form on the inner wall 11. Here, the condensation water on the inner wall 11 flows to the first water receiving plate 21 under the influence of its own gravity, and at least part of the condensation water on the first water receiving plate 21 can flow to the drainage structure 22 through the front wall 12. At this time, the drainage structure 22 can guide the condensation water to flow downward, so that the condensation water can drip onto the water receiving tray 10 on the lower side of the drainage structure 22. Therefore, the rear frame of the present invention can drain the condensation water generated by itself into the water receiving tray 10.

[0034] It should be noted that the present disclosure does not limit the specific structure of the drainage structure 22, and the present disclosure will be described in detail in the following embodiments. In addition, at least part of the condensation water on the first water receiving plate 21 can flow to the drainage structure 22 through the front wall 12 under the influence of its own gravity. For example, in some embodiments, the first water receiving plate 21 can extend from the back to the front and gradually tilt downward, so that the condensation water on the first water receiving plate 21 can automatically flow to the drainage structure 22.

[0035] In some embodiments of the present disclosure, reference Figure 2As shown in , the drainage structure 22 may include a first drainage component 3, and the first drainage component 3 includes a first water guide rib 31. The first water guide rib 31 may be connected between the first water receiving plate 21 and the front wall 12, and extend in the up-down direction. In this way, the condensation water on the first water receiving plate 21 may flow downward along the first water guide rib 31 and through the front wall 12, thereby facilitating the condensation water to drip onto the water receiving tray 10.

[0036] In some embodiments of the present disclosure, reference Figure 2 As shown in , the first drainage assembly 3 may include a second water guide rib 32, which is connected to the front wall 12 and gradually extends downward in a direction close to the first water guide rib 31. In this way, the condensation water between the first water guide rib 31 and the second water guide rib 32 can gradually converge when flowing downward, thereby facilitating the condensation water to drip onto the water receiving tray 10.

[0037] In some embodiments of the present disclosure, reference Figure 2 As shown in , the first water receiving plate 21 can be connected to a first water retaining rib 33 on the side away from the inner wall 11, and the first water retaining rib 33 is connected to the first water guiding rib 31. In this way, the condensation water on the first water receiving plate 21 can be prevented from dripping from the side away from the inner wall 11, ensuring that the condensation on the first water receiving plate 21 can basically drip into the water receiving tray 10 through the first water guiding rib 31. Here, the first water receiving plate 21 can have a width in the left and right directions, and the present disclosure can adaptively design the width of the first water receiving plate 21 as needed, which will not be elaborated in detail here. In addition, in the actual arrangement, the first water retaining rib 33 can protrude upward from the first water guiding rib 31.

[0038] In some embodiments of the present disclosure, reference Figure 2 As shown in the figure, the first water guide rib 31 includes a first sub-rib 311 and a second sub-rib 312 connected to each other. The first sub-rib 311 is connected to the first water receiving plate 21 and can be gradually extended downward in a direction close to the inner wall 11. The second sub-rib 312 is connected to the front wall 12. In this way, the condensation water on the first water guide rib 31 can be gradually gathered when flowing downward, which is also conducive to the condensation water dripping onto the water receiving tray 10.

[0039] Optionally, refer to Figure 2 As shown in , a first reinforcing rib 34 is further connected between the second rib 312 and the front wall 12. In this way, the connection strength between the second rib 312 and the front wall 12 can be improved, and the flow guiding effect of the second rib 312 can be ensured.

[0040] Optionally, refer to Figure 2 As shown in FIG. , the second rib 312 may extend in a vertical direction, which is not limited in the present disclosure.

[0041] Optionally, the second rib 312 may have a length in the up and down directions, and the present disclosure does not limit the length of the second rib 312. For example, in some embodiments, the lower end of the second rib 312 may abut against the water receiving tray 10 so that condensation water on the second rib 312 flows directly to the water receiving tray 10, and the present disclosure does not limit this.

[0042] In some embodiments of the present disclosure, reference Figure 2 As shown in , the drainage structure 22 may include a second drainage component 4, and the second drainage component 4 includes a second water receiving plate 41 connected to the front wall 12, and the second water receiving plate 41 is arranged on the lower side of the first water receiving plate 21. Here, the condensation water on the first water receiving plate 21 can drip onto the second water receiving plate 41 through the front wall 12, and the condensation water on the second water receiving plate 41 can flow downward, thereby dripping onto the upper water receiving tray 10. In some embodiments, the second water receiving plate 41 can gradually extend downward in a direction away from the front wall 12, thereby allowing the condensation water dripping onto the second water receiving plate 41 to automatically flow downward, thereby also realizing the drainage function of the drainage structure 22, that is, the function of guiding the condensation water flowing out of the first water receiving plate 21 to flow downward.

[0043] In some embodiments of the present disclosure, reference Figure 2 As shown in , a second water retaining rib 42 can be connected between the front wall 12 and the second water receiving plate 41, and the second water retaining rib 42 is provided on the left and right sides of the second water receiving plate 41. In this way, the second water retaining rib 42 can prevent the condensation water on the second water receiving plate 41 from accidentally flowing out along the left and right sides.

[0044] In some embodiments of the present disclosure, reference Figure 2 As shown in , the front wall 12 and the second water receiving plate 41 may be connected with a second reinforcing rib 43. In this way, the connection strength between the front wall 12 and the second water receiving plate 41 can be improved.

[0045] In some embodiments of the present disclosure, reference Figure 2 As shown in , the drainage structure 22 may include a drainage rack 5, which is arranged at the lower side of the first water receiving plate 21, and the drainage rack 5 has a water receiving groove 51 and a drain port 52 connected to the water receiving groove 51. In this way, the condensation water on the first water receiving plate 21 can flow into the water receiving groove 51 through the front wall 12, flow out of the water receiving groove 51 through the drain port 52, and drip downward onto the water receiving tray 10, thereby also realizing the drainage function of the drainage structure 22.

[0046] In some embodiments of the present disclosure, reference Figure 2As shown in , the drainage rack 5 may have a third water guide rib 53 connected to the drain port 52, and the third water guide rib 53 extends in the up-down direction. In this way, the third water guide rib 53 can continue to guide the condensation water flowing out of the drain port 52 to flow downward, thereby shortening the distance between the condensation water and the water receiving tray 10 when dripping, and preventing the generation of a loud dripping sound.

[0047] Optionally, refer to Figure 2 As shown in , the drainage rack 5 may also have a third water receiving plate 54 connected to the third water guide rib 53. Here, part of the condensation water flowing out of the drain port 52 flows downward through the third water guide rib 53, and the other part drips onto the third water receiving plate 54 and drips through the third water receiving plate 54. In this way, the drainage effect of the drainage rack 5 can be improved by using the third water receiving plate 54. In some embodiments, the third water receiving plate 54 may also gradually extend downward in a direction away from the front wall 12, and the present disclosure does not limit this.

[0048] In some embodiments of the present disclosure, reference Figure 2 and Figure 3 As shown in , the water receiving groove 51 has a first sub-groove 511 and a second sub-groove 512 that are connected. The first sub-groove 511 is arranged on the front wall 12 and is connected to the drain port 52, and the second sub-groove 512 is arranged on the inner wall 11. In this way, the water receiving amount of the water receiving groove 51 can be increased by using the second sub-groove 512 on the one hand, and the condensation water at the bottom of the first water receiving plate 21 can drip into the second sub-groove 512 on the other hand, thereby improving the drainage effect of the drainage structure 22, and further preventing the condensation water on the rear frame body 1 from dripping onto other parts. Here, in some embodiments, the drainage rack 5 can be connected to the following connecting bracket 30, and when the connecting bracket 30 is connected to the rear frame body 1, the drainage rack 5 is arranged on the front wall 12. Alternatively, in other embodiments, the drainage rack 5 can also be connected to the front wall 12 alone, and the present disclosure does not limit this.

[0049] In some embodiments of the present disclosure, reference Figure 2 As shown in , in the manner in which the drainage structure 22 includes the above-mentioned first drainage component 3, the drainage structure 22 may include a second drainage component 4, the second drainage component 4 includes a second water receiving plate 41 connected to the front wall 12, and the drainage rack 5 is arranged between the first water guide rib 31 and the second water receiving plate 41. In this way, the condensation water on the first water receiving plate 21 can flow into the water receiving groove 51 of the drainage rack 5 through the guidance of the first water guide rib 31, and flow downward from the drain port 52 to the second water receiving plate 41, and then drip onto the water receiving tray 10 through the second water receiving plate 41, thereby effectively improving the drainage effect of the drainage structure 22.

[0050] Next, the present disclosure will provide a detailed introduction to the flow process of condensation water on the rear frame in combination with the above specific implementations. Figures 1 to 3As shown in the figure, the condensation water on the inner wall 11 first flows to the first water receiving plate 21, then flows forward, and flows downward along the front wall 12 guided by the first water guide rib 31 and the second water guide rib 32, then drips into the water receiving groove 51, and flows out of the water receiving groove 51 through the drain port 52. At this time, the condensation water continues to flow downward guided by the third water guide rib 53, and drips onto the second water receiving plate 41. In this process, the condensation water on the third water receiving plate 54 can also drip onto the second water receiving plate 41. After that, the condensation water on the second water receiving plate 41 continues to flow downward and drips onto the water receiving tray 10. In this way, the condensation water generated on the rear frame can be drained into the water receiving tray 10, and the drainage effect is good.

[0051] According to a second aspect provided by the present disclosure, an indoor unit is provided, comprising the rear frame as described above. The indoor unit has all the beneficial effects of the rear frame as described above, which will not be described in detail in the present disclosure.

[0052] In some embodiments of the present disclosure, reference Figures 1 to 3 As shown in , the indoor unit may include an evaporator 20 and a connecting bracket 30, the lower side of the evaporator 20 is connected to the rear frame body 1 through the connecting bracket 30, and the first water receiving plate 21 may be close to the end 201 of the evaporator 20 and arranged close to the connecting bracket 30. Here, the lower side of the inner wall 11 and the part close to the end 201 of the evaporator 20 are prone to produce condensation water, therefore, arranging the first water receiving plate 21 at this position can ensure that the condensation water on the rear frame flows to the first water receiving plate 21 as much as possible, and in addition, the water receiving tray 10 can be arranged lower, shortening the distance for the condensation water on the water receiving tray 10 to be drained into the water receiving tray 10, and ensuring the drainage effect of the drainage structure 22 on the condensation water.

[0053] In some embodiments of the present disclosure, a water receiving groove may be formed on the connecting bracket 30 so that condensed water on the evaporator 20 can drip into the water receiving groove, which is not limited in the present disclosure.
