Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a water tray structure and an air conditioner having the same. Background Technology

[0002] During the cooling process of a cabinet air conditioner, water vapor in the air loses heat and condenses into liquid water when it comes into contact with the cool evaporator surface, thus forming water droplets. As the cooling process continues, the number and accumulation of water droplets on the evaporator surface gradually increases. To ensure the normal operation of the air conditioning system and prevent water droplets from overflowing and damaging the equipment, a bottom drip tray is installed below the evaporator. When there are many water droplets in the evaporator drip tray, the water droplets will drain from the drip inlet of the evaporator drip tray onto the bottom drip tray.

[0003] However, because the distance between the drain nozzle and the bottom drip tray is too high, the water droplets are accelerated by gravity during their fall, which causes impact and vibration, resulting in a loud dripping sound. This causes the air conditioner to generate noise during the cooling process, affecting the user experience. Summary of the Invention

[0004] The main objective of this invention is to provide a water tray structure and an air conditioner having the same, so as to solve the problem of noise generated by air conditioners during the cooling process in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a water receiving tray structure is provided, comprising: a cylindrical body, having an inlet end and an outlet end disposed opposite to each other along the axial direction of the cylindrical body, the outlet end of the cylindrical body being provided with a protrusion extending away from the inlet end along the axial direction of the cylindrical body; and partitions provided in the inner cavity of the cylindrical body, the partitions all extending along the axial direction of the cylindrical body to divide the inner cavity of the cylindrical body.

[0006] Furthermore, there are multiple partitions and multiple protrusions, with each protrusion and partition corresponding to the other, and the partitions are spaced apart along the circumferential direction of the cylinder; each protrusion is an arc-shaped protrusion structure.

[0007] Furthermore, the outlet end of the cylinder has a first boundary arc segment that is closest to the inlet end, and the outlet end of the cylinder has a second boundary arc segment that is furthest from the inlet end. At least one protrusion is disposed on the first boundary arc segment, at least one protrusion is disposed on the second boundary arc segment, and at least one protrusion is disposed between the first boundary arc segment and the second boundary arc segment.

[0008] Furthermore, the projection of the inlet end of the cylinder onto the preset projection surface is the first projection line segment, the projection of the first boundary arc segment onto the preset projection surface is the first connection point, the projection of the second boundary arc segment onto the preset projection surface is the second connection point, and the angle β between the line connecting the first connection point and the second connection point and the first projection line segment is 40°; wherein, the preset projection surface is perpendicular to the axial section of the cylinder and extends along the axial direction of the cylinder.

[0009] Furthermore, each separator has a first radial end face and a second radial end face that are arranged opposite to each other along the radial direction of the cylinder. The first radial end face is connected to the inner wall of the cylinder, and the second radial end face is arranged toward the central axis of the cylinder.

[0010] Furthermore, each separator has a first axial end face and a second axial end face that are arranged opposite to each other along the axial direction of the cylinder. The first axial end face is arranged closer to the inlet end than the second axial end face, and the first axial end face and the second radial end face are connected by a first arc-shaped transition section.

[0011] Furthermore, along the radial direction of the cylinder, from the second radial end face to the first radial end face, the distance between the second axial end face and the first axial end face gradually increases along the axial direction of the cylinder.

[0012] Furthermore, the second axial end face and the second radial end face are connected by a second arc-shaped transition section; the second axial end face and the cylinder are connected by a third arc-shaped transition section.

[0013] Furthermore, the water receiving tray structure also includes a first tray body, with a cylindrical body positioned below the first tray body, and the inner cavity of the first tray body being connected to the inlet end.

[0014] According to another aspect of the present invention, an air conditioner is provided, including a second plate body, the air conditioner further including the above-described water receiving tray structure, the second plate body being located below the cylinder body, the second plate body having a first tray surface for receiving liquid dripping from the outlet end of the cylinder body.

[0015] Furthermore, along the distribution direction of the second disc and the cylinder, the minimum distance between the first disc surface and the protrusion is h; where h < 43 mm.

[0016] The present invention provides a water receiving tray structure comprising a cylindrical body. A separator is provided within the inner cavity of the cylindrical body to divert liquid flowing in from the inlet. Due to the collision between the separator and the liquid, the separator reduces the liquid's flow velocity and prevents the diverted liquid from re-converging within the cylindrical body. This reduces the flow velocity of the liquid exiting the outlet, preventing excessive dripping noise when the liquid enters the bottom water receiving tray, thus avoiding noise during the air conditioner's cooling process and solving the noise problem inherent in existing air conditioners. Furthermore, a protrusion guides the downward flow of the liquid, ensuring a stable flow from the cylindrical body to the bottom water receiving tray, preventing liquid from overflowing the tray.

[0028] Please refer to Figures 1 to 5 The present invention provides a water receiving tray structure, comprising: a cylindrical body 10, which has an inlet end 13 and an outlet end 14 disposed opposite to each other along the axial direction of the cylindrical body 10, the outlet end 14 of the cylindrical body 10 being provided with a protrusion 11, the protrusion 11 extending away from the inlet end 13 along the axial direction of the cylindrical body 10; and a partition 12 provided in the inner cavity of the cylindrical body 10, the partition 12 extending along the axial direction of the cylindrical body 10 to divide the inner cavity of the cylindrical body 10.

[0029] The water receiving tray structure of the present invention includes a cylindrical body 10. A separator 12 is provided within the inner cavity of the cylindrical body 10, allowing liquid flowing in from the inlet end 13 to be diverted by the separator 12. Due to the collision between the separator 12 and the liquid, the separator 12 reduces the liquid's flow velocity and prevents the diverted liquid from re-converging within the cylindrical body 10. This reduces the flow velocity of the liquid flowing out from the outlet end 14, preventing significant dripping noise when the liquid from the cylindrical body 10 enters the bottom water receiving tray, thus avoiding noise generation during the air conditioning cooling process and solving the noise problem of air conditioning during cooling in the prior art. Simultaneously, a protrusion 11 guides the downward flow of the liquid, ensuring a stable flow from the cylindrical body 10 to the bottom water receiving tray, thereby preventing liquid from flowing outside the bottom water receiving tray.

[0030] In this embodiment, the water receiving tray structure also includes a first tray body 22, and a cylinder body 10 is disposed below the first tray body 22. The inner cavity of the first tray body 22 is connected to the inlet end 13.

[0031] Specifically, the first plate 22 is the evaporator water receiving plate, the cylinder 10 is the drain nozzle, the liquid is water, and the liquid in the evaporator water receiving plate flows from the inlet end 13 into the cylinder 10.

[0032] In this embodiment, there are multiple partitions 12 and multiple protrusions 11. The multiple protrusions 11 and multiple partitions 12 are arranged in a one-to-one correspondence. The multiple partitions 12 are spaced apart along the circumferential direction of the cylinder 10. Each protrusion 11 is an arc-shaped protrusion structure.

[0033] Specifically, multiple separators 12 can work together to reduce the flow rate of the liquid, and multiple protrusions 11 can work together to guide the liquid flow at the outlet end 14, so that the liquid in the cylinder 10 can flow to the bottom water receiving tray from multiple directions, thus preventing the liquid in the cylinder 10 from not being able to flow out quickly.

[0034] Specifically, there are four separators 12, which are arranged at ninety-degree intervals on the inner wall of the cylinder 10.

[0035] In this embodiment, the outlet end 14 of the cylinder 10 has a first boundary arc segment that is closest to the inlet end 13, and the outlet end 14 of the cylinder 10 has a second boundary arc segment that is furthest from the inlet end 13. At least one protrusion 11 is disposed on the first boundary arc segment, at least one protrusion 11 is disposed on the second boundary arc segment, and at least one protrusion 11 is disposed between the first boundary arc segment and the second boundary arc segment.

[0036] Specifically, there are four protrusions 11, with two protrusions 11 respectively located on the first boundary arc segment and the second boundary arc segment. The remaining two protrusions 11 are arranged opposite each other along the radial direction of the cylinder 10, and both remaining two protrusions 11 are located between the first boundary arc segment and the second boundary arc segment.

[0037] In this embodiment, the projection of the inlet end 13 of the cylinder 10 onto the preset projection plane is the first projection line segment 17, the projection of the first boundary arc segment onto the preset projection plane is the first connection point 15, and the projection of the second boundary arc segment onto the preset projection plane is the second connection point 16. The angle β between the line connecting the first connection point 15 and the second connection point 16 and the first projection line segment 17 is 40°. The preset projection plane is perpendicular to the axial section of the cylinder 10 and extends along the axial direction of the cylinder 10. This arrangement helps the separator 12 to uniformly separate the liquid, reduce the liquid velocity, and prevent it from converging.

[0038] Specifically, the thickness t of the separator 12 is in the range of 2mm ≤ t ≤ 3mm. This design provides effective resistance to the liquid while ensuring that the separator 12 does not interfere with the liquid discharge, allowing the cylinder 10 to drain efficiently.

[0039] In this embodiment, each separator 12 has a first radial end face 18 and a second radial end face 19 disposed opposite to each other along the radial direction of the cylinder 10. The first radial end face 18 is connected to the inner wall of the cylinder 10, and the second radial end face 19 is disposed toward the central axis of the cylinder 10.

[0040] Specifically, there are flow gaps between the four second radial end faces 19 for liquid to flow through, which helps the cylinder 10 to discharge liquid more effectively and reduce blockage.

[0041] In this embodiment, each separator 12 has a first axial end face 20 and a second axial end face 21 that are arranged opposite to each other along the axial direction of the cylinder 10. The first axial end face 20 is arranged closer to the inlet end 13 than the second axial end face 21. The first axial end face 20 and the second radial end face 19 are connected by a first arc-shaped transition section.

[0042] Specifically, the inner diameter of the first arc-shaped transition section is 0.5 mm. This design can increase the durability of the separator 12, reduce stress concentration in the separator 12, and increase the service life of the separator 12. Secondly, the setting of the first arc-shaped transition section can also reduce turbulence and promote smoother liquid flow.

[0043] In this embodiment, along the radial direction of the cylinder 10, from the second radial end face 19 to the first radial end face 18, the distance between the second axial end face 21 and the first axial end face 20 gradually increases in the axial direction of the cylinder 10. This design helps to form a drainage slope on the second axial end face 21, making it easier for liquid on the second radial end face 19 to flow from the second axial end face 21 to the protrusion 11. This helps the cylinder 10 to discharge liquid more effectively, reduces blockage, and also prevents turbulence from forming in the cylinder.

[0044] Specifically, the first radial end face 18 extends from the inlet end 13 to the bottom of the protrusion 11.

[0045] Specifically, the second axial end face 21 has a length of 4 mm and a width of 2 mm.

[0046] Specifically, the parts of the cylinder 10 that come into contact with the separator 12 and the protrusion 11 are smoothed, which helps the cylinder 10 to discharge liquid more effectively and reduce blockage.

[0047] In this embodiment, the second axial end face 21 and the second radial end face 19 are connected by a second arc-shaped transition section; the second axial end face 21 and the cylinder 10 are connected by a third arc-shaped transition section.

[0048] Specifically, this design ensures that the water flows down along the second axial end face 21 and the protrusion 11, rather than down along the recess on the outlet end 14 where the protrusion 11 is not provided, thus avoiding turbulence or liquid splashing, and further preventing the liquid from hitting the bottom water receiving tray and generating noise.

[0049] Specifically, the inner diameter of the second arc-shaped transition section is 0.5 mm, and the inner diameter of the third arc-shaped transition section is 0.5 mm.

[0050] The present invention also provides an air conditioner including a second plate 24, the air conditioner further including the above-mentioned water receiving tray structure, the second plate 24 being located below the cylinder 10, the second plate 24 having a first plate surface 23 for receiving liquid dripping from the outlet end 14 of the cylinder 10.

[0051] Specifically, the second tray 24 is the bottom water receiving tray.

[0052] In this embodiment, along the distribution direction of the second disc 24 and the cylinder 10, the minimum distance between the first disc surface 23 and the protrusion 11 is h; where h < 43 mm.

[0053] Specifically, h < 43 mm prevents excessive velocity of the liquid as it falls from the cylinder 10. This ensures that the liquid lands on the bottom drip tray in a relatively inconspicuous or imperceptible manner, thus reducing the risk of noise. Furthermore, this height restriction helps prevent any potential damage to the cylinder 10 and the second tray 24, as the impact force of the liquid could affect these components.

[0054] Specifically, the distance between the bottom end of the protrusion 11 on the second boundary arc segment and the first disk surface 23 is the minimum distance between the first disk surface 23 and the protrusion 11.

[0055] Specifically, the second disc 24 is provided with a dripping range 29, which is aligned with the cylinder 10.

[0056] In practical implementation, Ansys simulation software was used to simulate the liquid velocity as it travels from inlet 13 to outlet 14. By comparing the liquid velocity at outlet 14, the effectiveness of the drip tray structure in this application in reducing the liquid velocity was verified. The velocity at inlet 13 was set to a constant 0.5 m / s, and the pressure at outlet 14 was set to standard atmospheric pressure. Therefore, the liquid velocity at outlet 14 was observed under the same conditions. It was found that the highest velocity at outlet 14 without the separator 12 was 1.03 m / s, while the highest liquid velocity at outlet 14 in this application was 0.654 m / s. Therefore, the drip tray structure in this application can effectively change the liquid velocity.

[0057] Increasing the length of the drain nozzle places higher demands on the mold, increasing costs and making it difficult to implement; increasing the thickness of the bottom drip tray also affects the overall assembly of the bottom drip tray. However, this application, through design modifications to the interior of the cylinder 10 and the outlet end 14, can perfectly solve the knocking sound generated when condensed liquid is submerged by simply changing the drain nozzle. This method avoids the need to increase the length of the drain nozzle to shorten the distance between the drain nozzle and the bottom drip tray to reduce the gravitational potential energy of the liquid, and also avoids the need to increase the thickness of the bottom drip tray to shorten the distance between the two to reduce the gravitational potential energy of the liquid. Therefore, this application has the advantages of avoiding changes to the assembly method and avoiding increased mold costs, thus reducing production costs.

[0058] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0059] The water receiving tray structure of the present invention includes a cylindrical body 10. A separator 12 is provided within the inner cavity of the cylindrical body 10, allowing liquid flowing in from the inlet end 13 to be diverted by the separator 12. Due to the collision between the separator 12 and the liquid, the separator 12 reduces the liquid's flow velocity and prevents the diverted liquid from re-converging within the cylindrical body 10. This reduces the flow velocity of the liquid flowing out from the outlet end 14, preventing significant dripping noise when the liquid from the cylindrical body 10 enters the bottom water receiving tray, thus avoiding noise generation during the air conditioning cooling process and solving the noise problem of air conditioning during cooling in the prior art. Simultaneously, a protrusion 11 guides the downward flow of the liquid, ensuring a stable flow from the cylindrical body 10 to the bottom water receiving tray, thereby preventing liquid from flowing outside the bottom water receiving tray.

[0060] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
