[0001] The present invention relates to the technical field of air conditioning, and in particular to a water receiving tray structure and an air conditioner having the same. Background Art

[0002] During the refrigeration process of the cabinet air conditioner, when the water vapor in the air contacts the surface of the evaporator with a lower temperature, it loses heat and condenses into liquid water, that is, water droplets are produced. As the refrigeration process continues, the water droplets on the surface of the evaporator gradually increase and accumulate. In order to ensure the normal operation of the air conditioning system and prevent water droplets from overflowing and causing damage to the equipment, a bottom water tray is installed under the evaporator. When there are many water droplets in the evaporator water tray, the water droplets will be discharged from the water receiving nozzle of the evaporator water tray to the bottom water tray.

[0003] However, since the distance between the drain nozzle and the bottom water tray is too high, the water droplets are accelerated by gravity during the falling process, causing impact and vibration, resulting in a loud dripping sound, causing the air conditioner to produce noise during the cooling process, affecting the user experience.

[0028] Please refer to Figures 1 to 5 The present invention provides a water receiving tray structure, comprising: a cylinder 10, wherein the cylinder 10 has an inlet end 13 and an outlet end 14 which are arranged opposite to each other in the axial direction of the cylinder 10, and the outlet end 14 of the cylinder 10 is provided with a protrusion 11, and the protrusion 11 extends in the axial direction of the cylinder 10 in a direction away from the inlet end 13; a partition 12 is provided in the inner cavity of the cylinder 10, and the partition 12 extends in the axial direction of the cylinder 10 to partition the inner cavity of the cylinder 10.

[0029] The water receiving tray structure of the present invention includes a cylinder 10. A partition 12 is provided in the inner cavity of the cylinder 10 so that the liquid flowing in from the inlet end 13 can be diverted by the partition 12. Since the partition 12 collides with the liquid, the partition 12 can reduce the flow rate of the liquid and prevent the diverted liquid from re-gathering in the cylinder 10, that is, the flow rate of the liquid flowing out from the outlet end 14 is reduced, and a loud dripping sound is avoided when the liquid flowing out of the cylinder 10 enters the bottom water receiving tray, and the air conditioner is prevented from generating noise during the refrigeration process, thereby solving the problem of the air conditioner generating noise during the refrigeration process in the prior art. At the same time, the convex portion 11 is provided to guide the direction of the liquid flow, so that the liquid can stably flow from the cylinder 10 to the bottom water receiving tray, thereby preventing the liquid from flowing out of the bottom water receiving tray.

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

[0031] Specifically, the first tray 22 is the evaporator water tray, the cylinder 10 is the drain nozzle, the liquid is water, and the liquid in the evaporator water tray 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 the multiple partitions 12 are arranged one by one, and the multiple partitions 12 are arranged at intervals along the circumferential direction of the cylinder 10; each protrusion 11 is an arc-shaped protrusion structure.

[0033] Specifically, multiple partitions 12 can jointly reduce the flow rate of the liquid, and multiple protrusions 11 can jointly guide the flow of liquid at the outlet end 14, so that the liquid in the cylinder 10 can flow to the bottom water receiving tray from multiple directions, avoiding the liquid in the cylinder 10 from being unable to flow out quickly.

[0034] Specifically, there are four partitions 12 , and the four partitions 12 are arranged on the inner wall of the cylinder 10 at intervals of ninety degrees.

[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, the outlet end 14 of the cylinder 10 has a second boundary arc segment that is farthest from the inlet end 13, at least one protrusion 11 is arranged on the first boundary arc segment, at least one protrusion 11 is arranged on the second boundary arc segment, and at least one protrusion 11 is arranged between the first boundary arc segment and the second boundary arc segment.

[0036] Specifically, there are four protrusions 11, two of which are respectively arranged on the first boundary arc segment and the second boundary arc segment. The remaining two protrusions 11 are arranged opposite to each other along the radial direction of the cylinder 10, and the remaining two protrusions 11 are both arranged 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 on the preset projection plane is the first projection line segment 17, the projection of the first boundary arc segment on the preset projection plane is the first connection point 15, the projection of the second boundary arc segment on the preset projection plane is the second connection point 16, and the angle β between the line between the first connection point 15 and the second connection point 16 and the first projection line segment 17 is 40°; wherein the preset projection plane is perpendicular to the axial section of the cylinder 10, and the preset projection plane extends along the axial direction of the cylinder 10. Such a setting helps the partition 12 to evenly 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 2 mm ≤ t ≤ 3 mm. Such a configuration can provide effective resistance to the liquid while ensuring that the separator 12 does not interfere with the discharge of the liquid, allowing the cylinder 10 to drain water efficiently.

[0039] In this embodiment, each partition 12 has a first radial end face 18 and a second radial end face 19 which are arranged 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 arranged 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 partition 12 has a first axial end face 20 and a second axial end face 21 which are relatively arranged along the axial direction of the cylinder 10. The first axial end face 20 is arranged close to the inlet end 13 relative to the second axial end face 21, and 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. Such a design can increase the durability of the separator 12, reduce stress concentration of 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 flow of the liquid.

[0043] In this embodiment, along the radial direction of the cylinder 10, the distance between the second axial end face 21 and the first axial end face 20 along the axial direction of the cylinder 10 gradually increases from the second radial end face 19 to the first radial end face 18. Such a design helps to form a drainage slope on the second axial end face 21, so that the liquid on the second radial end face 19 can more easily flow from the second axial end face 21 to the protrusion 11, which helps the cylinder 10 to discharge the liquid more effectively, reduce blockage, and prevent the liquid from generating turbulence in the cylinder.

[0044] Specifically, the first radial end surface 18 extends from the inlet end 13 to the bottom of the protruding portion 11 .

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

[0046] Specifically, the portion of the cylinder 10 that contacts the partition 12 and the raised portion 11 is smoothed, which helps the cylinder 10 to discharge liquid more effectively and reduce clogging.

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

[0048] Specifically, such a design can ensure that water flows down along the second axial end face 21 and the raised portion 11, but does not flow down along the recessed portion on the outlet end 14 where the raised portion 11 is not provided, thereby avoiding turbulence or liquid splashing, and further avoiding noise caused by liquid hitting the bottom water receiving tray.

[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 tray 24 . The air conditioner also includes the above-mentioned water receiving tray structure. The second tray 24 is located below the cylinder 10 . The second tray 24 has a first tray surface 23 for receiving liquid dripping from the outlet end 14 of the cylinder 10 .

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

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

[0053] Specifically, h < 43 mm can prevent the liquid from falling from the cylinder 10 at too high a speed. It can ensure that the liquid falls onto the bottom water tray in a relatively unnoticeable or undetectable manner, thereby reducing the risk of noise. In addition, this height limit can also help prevent any potential damage to the cylinder 10 and the second tray 24, as the impact force of the liquid may affect these components.

[0054] Specifically, the distance between the bottom end of the protrusion 11 disposed 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, a dripping range 29 is provided on the second plate 24 , and the dripping range 29 is arranged to be aligned with the cylinder 10 .

[0056] In the specific implementation, the Ansys simulation software is used to simulate the speed of the liquid in the process of the liquid reaching the outlet end 14 from the inlet end 13. By comparing the liquid speed at the outlet end 14, it is verified whether the water receiving tray structure of the present application can effectively reduce the speed of the liquid. The speed of the inlet end 13 is set to the same speed of 0.5m / s, and the pressure of the outlet end 14 is set to the standard atmospheric pressure. Therefore, the speed of the liquid reaching the outlet end 14 is checked under the same speed. It is found that the maximum speed of the outlet end 14 without the partition 12 is 1.03m / s, and the maximum liquid speed of the outlet end 14 of the present application is 0.654m / s. Therefore, the water receiving tray structure of the present application can effectively change the speed of the liquid.

[0057] Since increasing the length of the drain nozzle places high demands on the mold, it not only increases the cost but is also difficult to implement; increasing the thickness of the bottom water receiving tray will also affect the overall assembly of the bottom water receiving tray. However, the present application, by making design changes inside the cylinder 10 and the outlet end 14, only needs to change the drain nozzle to perfectly solve the hitting sound generated when the condensed liquid falls. This method does not need to increase the length of the drain nozzle to shorten the distance between the drain nozzle and the bottom water receiving tray to reduce the gravitational potential energy under the liquid, and also avoids increasing the thickness of the bottom water receiving tray to shorten the distance between the two to shorten the distance between the drain nozzle and the bottom water receiving tray to reduce the gravitational potential energy under the liquid; therefore, the present application has the advantages of avoiding changing the assembly method and avoiding increasing the mold cost, which can reduce production costs.

[0058] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0059] The water receiving tray structure of the present invention includes a cylinder 10. A partition 12 is provided in the inner cavity of the cylinder 10 so that the liquid flowing in from the inlet end 13 can be diverted by the partition 12. Since the partition 12 collides with the liquid, the partition 12 can reduce the flow rate of the liquid and prevent the diverted liquid from re-gathering in the cylinder 10, that is, the flow rate of the liquid flowing out from the outlet end 14 is reduced, and a loud dripping sound is avoided when the liquid flowing out of the cylinder 10 enters the bottom water receiving tray, and the air conditioner is prevented from generating noise during the refrigeration process, thereby solving the problem of the air conditioner generating noise during the refrigeration process in the prior art. At the same time, the convex portion 11 is provided to guide the direction of the liquid flow, so that the liquid can stably flow from the cylinder 10 to the bottom water receiving tray, thereby preventing the liquid from flowing out of the bottom water receiving tray.

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

[0061] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
