Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to a duct drainage structure and an air conditioner. Background Technology

[0002] To effectively collect and manage condensation, air conditioners typically feature a large drip tray. While this design does collect condensation to some extent, its large size often occupies significant internal space, increasing the overall size of the air conditioner. Furthermore, traditional drip trays, limited by the condensation's flow path, are prone to splashing. This not only affects the cleanliness of the air conditioner's interior but can also cause condensation to drip onto circuit boards or other critical components, increasing safety hazards. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a duct drainage structure and an air conditioner to solve the technical problems of increased water tray volume and easy splashing caused by traditional drainage structures in related technologies.

[0005] Water tray;

[0006] The outer wall of the air duct is provided with a first water guide rib and a drain hole. The first water guide rib is inclined and the drain hole is located in the water guide path of the first water guide rib and is configured to guide the condensate on the outer wall of the air duct to the middle of the water receiving tray through the drain hole.

[0007] The projection of the outer wall of the air duct in the horizontal direction is located within the water receiving tray.

[0008] Furthermore, the first water guide rib is configured to guide the condensate on the outer wall of the air duct to the bottom of the outer wall of the air duct.

[0009] Furthermore, the drainage hole is located at the lower end of the first water guide rib; and / or

[0010] The drainage hole is located near the lower end of the first water guide rib.

[0011] Furthermore, the drainage hole is formed at the connection between the outer wall of the air duct and the first water guide rib.

[0012] Furthermore, the first water guide rib is integrally formed with the outer wall of the air duct.

[0013] Furthermore, the outer wall of the air duct is provided with a second water guide rib, which is spaced below the first water guide rib and is configured to guide the condensate overflowing from the first water guide rib to the water receiving tray.

[0014] Furthermore, the second water guide rib is inclined and in the same direction as the first water guide rib.

[0015] Furthermore, the vertical projection of the first water guide rib covers the second water guide rib.

[0016] Furthermore, the air duct drainage structure also includes: an inner wall of the air duct, wherein the inner wall of the air duct is provided with a plurality of third water guiding ribs for guiding the condensate on the inner wall of the air duct to the water receiving tray.

[0017] This utility model also provides an air conditioner, including the air duct drainage structure described above.

[0018] Compared to existing technologies, this invention offers the following advantages: By providing a first water-guiding rib and a drain hole on the outer wall of the air duct, the condensate on the outer wall of the air duct can be effectively guided by the first water-guiding rib and drained by the drain hole, flowing towards the center of the water collection tray. This not only reduces the size of the water collection tray, saving internal space in the air conditioner, but also prevents condensate from being diverted to the edge of the water collection tray and splashing.

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0027] In the embodiments of this utility model, such as Figures 1-3 As shown, the duct drainage structure includes: a water receiving tray 1 and an outer wall 2 of the duct; the outer wall 2 of the duct is provided with a first water guiding rib 3 and a drain hole 4, the first water guiding rib 3 is inclined, the drain hole 4 is located in the water guiding path of the first water guiding rib 3, and is configured to guide the condensate of the outer wall 2 of the duct to the middle of the water receiving tray 1 through the drain hole 4; wherein, the projection of the outer wall 2 of the duct in the horizontal direction is located in the water receiving tray 1.

[0028] Specifically, in this embodiment of the invention, the air guide frame 8 has a channel structure, which is the air duct. A water receiving tray 1 is provided at the lower end of the air guide frame 8, and the projection of the outer wall 2 of the air duct in the horizontal direction is located in the water receiving tray 1, so as to ensure that the condensation on the outer wall 2 of the air duct can be effectively collected by the water receiving tray 1, and to avoid overflow or splashing that could damage the external components.

[0029] In this embodiment of the invention, a first water-guiding rib 3 is provided on the outer wall 2 of the air duct. The first water-guiding rib 3 is inclined to ensure that the condensate maintains a stable path during flow, avoids splashing, and improves the safety and cleanliness of the air conditioner. At the same time, it can effectively collect the condensate from the outer wall 2 of the air duct. In addition, a drain hole 4 is provided at the water guiding path of the first water guiding rib 3. The drain hole 4 can guide the condensed water from the water guiding path of the first water guiding rib 3 to the middle of the water receiving tray 1. On the one hand, it changes the original water guiding path of the condensed water, changing the way it drips from the edge of the water receiving tray 1 to dripping from the middle of the water receiving tray 1. This can reduce the actual size of the water receiving tray 1 and optimize the internal space of the air conditioner (i.e., if the water guiding volume of the outer wall 2 of the air duct is large, the size of the water receiving tray 1 needs to be set larger to ensure that the condensed water does not flow out of the water receiving tray 1). On the other hand, since the condensed water can drip to the middle of the water receiving tray 1, splashing can be avoided, thus protecting the internal components of the air conditioner.

[0030] This embodiment solves the problems of large space occupation and easy splashing of condensate in traditional water receiving trays by setting matching first water guide ribs 3 and drainage holes 4 on the outer wall 2 of the air duct. It also improves the overall performance and reliability of the air conditioner and provides users with a safer and more comfortable user experience.

[0031] In one embodiment, such as Figure 2 , Figure 3 As shown, the first water guide rib 3 is configured to guide the condensate on the outer wall 2 of the air duct to the bottom of the outer wall 2 of the air duct. Specifically, in order to receive the condensate from the bottom of the outer wall 2 of the air duct, this embodiment sets the first water guide rib 3 at the bottom of the outer wall 2 of the air duct, so that it can guide the condensate on the outer wall 2 of the air duct to its bottom.

[0032] In one embodiment, such as Figure 2 , Figure 3 As shown, the drain hole 4 is arranged near the lower end of the first water guide rib 3. Specifically, to facilitate the condensation on the outer wall 2 of the air duct to be guided into the middle of the water receiving tray 1 via the first water guide rib 3 and the drain hole 4, this embodiment sets the drain hole 4 near the lower end of the first water guide rib 3. In this way, the condensation flows from the upper end of the first water guide rib 3 to its lower end. During this process, most of the condensation can be guided to the middle of the water receiving tray 1 through the drain hole 4, while a small portion of the condensation will flow into the water receiving tray 1 from the lower end of the first water guide rib 3. On the one hand, this can play a certain role in diverting the flow, and on the other hand, it can also adapt the position of the drain hole 4 according to the shape and structure of the air guide frame 8 and / or the outer wall 2 of the air duct, reducing the processing precision of the drain hole 4. In addition, the lower end of the first water guide rib 3 extends outward and can be used as a reinforcing rib of the outer wall 2 of the air duct, avoiding the weakening of the structural strength of the outer wall 2 of the air duct located at the lower end of the first water guide rib 3 due to the interference of the position of the drain hole 4. Of course, in other embodiments, in order to facilitate the drainage of all the condensate from the first water guide rib 3 through the drain hole 4 to the middle position of the water receiving tray 1, the drain hole 4 is located at the lower end of the first water guide rib 3.

[0033] In one embodiment, such as Figure 2 , Figure 3 As shown, the drain hole 4 is formed at the connection between the outer wall 2 of the air duct and the first water guide rib 3. Specifically, in order to guide the condensate to the drain hole 4 and avoid a large amount of water accumulation at the first water guide rib 3, this embodiment sets the drain hole 4 at the connection between the outer wall 2 of the air duct and the first water guide rib 3, breaking the connection to form a drain hole 4 that connects to the middle of the water receiving tray 1. This avoids the formation of a stepped structure that would cause water accumulation, improves the drainage capacity of the drain hole 4, and allows the condensate to be guided to the middle of the water receiving tray 1. Preferably, the first water guide rib 3 is integrally formed with the outer wall 2 of the air duct.

[0034] In one embodiment, such as Figure 2 , Figure 3 As shown, the outer wall 2 of the air duct is provided with a second water guide rib 5. The second water guide rib 5 is spaced below the first water guide rib 3 and is configured to guide the condensate overflowing from the first water guide rib 3 to the water receiving tray 1. Specifically, in order to shorten the distance between the condensate and the water receiving tray 1 and prevent the condensate from splashing, this embodiment provides a second water guide rib 5 on the outer wall 2 of the air duct. The second water guide rib 5 is spaced below the first water guide rib 3. When the water volume is large, the condensate will overflow from the first water guide rib 3. At this time, the second water guide rib 5 can catch the overflowing condensate and guide it into the water receiving tray 1. Since the distance between the second water guide rib 5 and the water receiving tray 1 is closer than that between the first water guide rib 3 and the second water guide rib 5, the possibility of splashing is reduced when the condensate flows to the water receiving tray 1 after being guided by the second water guide rib 5.

[0035] Furthermore, in one embodiment, as Figure 2 , Figure 3 As shown, the second water guide rib 5 is inclined and has the same inclination direction as the first water guide rib 3. Specifically, in order to guide the condensate to the water receiving tray 1, this embodiment sets the second water guide rib 5 in an inclined manner to form an inclined water guiding path, similar to the first water guide rib 3, so that the condensate can be guided into the water receiving tray 1 through the second water guide rib 5.

[0036] Furthermore, in one embodiment, as Figure 2 , Figure 3 As shown, the vertical projection of the first water-guiding rib 3 covers the second water-guiding rib 5. Specifically, in order to collect the condensation overflowing from the first water-guiding rib 3, this embodiment defines the vertical projection of the first water-guiding rib 3 to cover the second water-guiding rib 5, such that the area of ​​the first water-guiding rib 3 is smaller than the area of ​​the second water-guiding rib 5. Thus, the second water-guiding rib 5 protrudes beyond the first water-guiding rib 3 to receive the condensation from the first water-guiding rib 3.

[0037] In one embodiment, such as Figure 4 As shown, the duct drainage structure further includes: an inner wall 6 of the duct, wherein the inner wall 6 is provided with a plurality of third water-guiding ribs 7, which are used to guide the condensate on the inner wall 6 of the duct to the water receiving tray 1. Specifically, in order to guide the condensate on the inner wall 6 of the duct to the water receiving tray 1, this embodiment provides a plurality of third water-guiding ribs 7 at intervals along the vertical direction of the inner wall 6 of the duct. The third water-guiding ribs 7 can guide the condensate formed on the inner wall 6 of the duct to the water receiving tray 1 at the bottom, and can also be used as reinforcing ribs to enhance the structural strength of the duct.

[0038] This embodiment also provides an air conditioner, including the air duct drainage structure described above. The specific structure of the air duct drainage structure is as described in the above embodiment. Since this air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
