Description

Technical Field

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

[0002] During the use of the air conditioner, a large amount of condensed water is generated, so the condensed water needs to be discharged. In the prior art, a water receiving pan is usually arranged under the heat exchanger, and the condensed water generated on the surface of the heat exchanger falls into the water receiving pan and is discharged through the drain port on the water receiving pan.

[0003] On the one hand, due to the small size and limited internal space of the air-conditioning cabinet, the space of the internal circulation air duct is narrow. When the air enters the internal circulation of the air conditioner, vortices are easily generated in the narrow space. The above-mentioned narrow space is mainly the bottom of the air duct and the bottom area of ​​the heat exchanger. After passing through the surface of the water tray, the air easily hits the side wall of the air duct and diffuses around, thereby affecting the absolute speed of the airflow in the air duct and the heat exchanger, affecting the air volume, and is not conducive to the heat exchange of the heat exchanger.

[0004] On the other hand, since the internal circulation and external circulation of the air-conditioning cabinet need to be separated, the air duct space is narrower. The narrow air duct will cause the air with lower temperature to hit the side wall of the air duct to form condensation water; or when the heat exchanger converts the high-temperature gas into low-temperature gas, condensation water is easily formed on the surface of the heat exchanger, and the condensation water is splashed onto the side wall of the air duct under the influence of the incoming wind; in the above two cases, the water receiving tray in the prior art is limited by space and it is difficult to collect the condensation water splashed onto the side wall of the air duct. The condensation water remains at the bottom of the air duct and cannot be discharged, which is easy to produce odor and affect the normal use of the air-conditioning cabinet.

[0005] The applicant has found that the prior art has at least the following technical problems: for the first situation mentioned above, the existing water receiving tray cannot alleviate the problem of air flowing through the surface of the water receiving tray and generating vortices at the bottom of the air duct, and the existing water receiving tray is difficult to collect condensed water splashed onto the side wall of the air duct.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Example 1

[0036] See also Figure 1-Figure 4 As shown, this embodiment provides a water receiving tray, which can be arranged at the lower part of the heat exchanger 200 like the water receiving tray in the prior art, and is used to receive condensed water generated on the surface of the heat exchanger 200. In addition, the water receiving tray in this embodiment includes a tray body 1 and a flow guide component 2 located on the tray body 1, wherein: the flow guide component 2 is used to connect with the air duct 100, and when the flow guide component 2 is connected with the side wall of the air duct 100, the air flowing through the water receiving tray can be guided to flow along the extension direction of the air duct 100, and the water on the side wall of the air duct 100 can be drained into the tray body 1.

[0037] On the one hand, after the air is heat-exchanged in the heat exchanger 200, it enters the air duct 100. The air is easy to hit the side wall of the air duct 100 in a narrow space and form vortices, which is particularly serious in the area between the bottom of the heat exchanger 200 and the bottom of the air duct 100 in the figure. On the other hand, due to space limitations, it is difficult to make the water receiving pan high. When the condensed water on the surface of the heat exchanger 200 is affected by the air flow, it is easy to splash onto the side wall of the air duct 100. Due to space limitations, it is difficult for the water receiving pan of the existing structure to collect the condensed water splashed onto the side wall of the air duct 100.

[0038] like Figure 3 and Figure 4 As shown, Figure 3 The solid arrow in the figure indicates the air flow direction. Figure 4The direction of the dotted arrow in the figure indicates the direction of condensed water flow. The water receiving tray in this embodiment can not only collect condensed water on the surface of the heat exchanger 200, but more importantly, can guide the air flowing through the surface of the water receiving tray to flow along the extension direction of the air duct 100 and to the air outlet 300 through the guide component 2, and use the air to flow in the same direction of the air duct 100 to reduce the vortex formed by the air in the air duct 100, thereby ensuring the air volume; and at the same time, the guide component 2 can guide the condensed water splashed onto the side wall of the air duct 100 into the tray body 1, preventing the condensed water that is affected by the air flow and hits the side wall of the air duct 100 from being collected by the water receiving tray. Even if the tray body 1 cannot be made higher due to space limitations, the guide component 2 can improve the water receiving capacity of the water receiving tray.

[0039] The tray body 1 is in the shape of a groove with an open upper end, which can temporarily store condensed water. A drain port is provided on the tray body 1 for connecting to a drain pipe to drain the water in the tray body 1.

[0040] As an optional embodiment, the above-mentioned flow guide component 2 includes a guide portion 21 and a connection portion 22, wherein:

[0041] The connecting portion 22 is used to connect with the side wall of the air duct 100 , the guiding portion 21 connects the disk body 1 and the connecting portion 22 , and the guiding portion 21 is used to allow air to flow smoothly toward the connecting portion 22 and to allow condensed water to flow smoothly into the disk body 1 .

[0042] The connection portion 22 has the function of connecting the guide portion 21 and the side wall of the air duct 100 . Specifically, the connection portion 22 can fit the side wall of the air duct 100 .

[0043] See also Figure 3 The guide portion 21 is used to make the air change direction smoothly for the first time. The airflow guided by the guide portion 21 flows smoothly to the connection portion 22, and changes direction again through the connection portion 22 and flows along the extension direction of the side wall of the air duct 100. Similarly, see Figure 4 Since the connection portion 22 fits the side wall of the air duct 100, the condensed water on the side wall of the air duct 100 can also stably flow into the disk body 1 through the guide portion 21, preventing the condensed water on the side wall of the air duct 100 from being unable to be collected and soaking the sealing sponge at the bottom of the air duct 100, generating odor and affecting the air conditioning performance.

[0044] Since the guide portion 21 plays a role in stabilizing the flow in the above process, as an optional implementation, see Figure 1 and Figure 2 As shown, in this embodiment, at least a portion of the guide portion 21 is in an arc shape.

[0045] The arc-shaped portion on the guiding portion 21 can make the air flow smoothly toward the connecting portion 22 and the side wall of the air duct 100, preventing the air from directly hitting the connecting portion 22 and the side wall of the air duct 100 and causing serious vortexes; similarly, the arc-shaped structure can make the condensed water flow smoothly into the disk body 1, preventing the condensed water from splashing out of the disk body 1 due to excessive flow rate.

[0046] In order to further make the airflow and water flow smoothly, as an optional implementation, see Figure 1 and Figure 2 As shown, the guiding part 21 of this embodiment includes a first guide plate 211 and a second guide plate 212, wherein: the first guide plate 211 is a flat plate and is arranged to be inclined upward, and the upper end of the first guide plate 211 is connected to the lower end of the second guide plate 212; the second guide plate 212 is an arc-shaped plate and the upper end of the second guide plate 212 is connected to the connecting part 22.

[0047] The function of the above-mentioned first guide plate 211 is to make the air after heat exchange in the heat exchanger 200 flow upward at an angle, initially changing the flow direction of the air. The air after passing through the first guide plate 211 then passes through the arc-shaped second guide plate 212, which can make the air turn more smoothly to flow in the direction along the connection part 22.

[0048] The coordinated structure of the first guide plate 211 and the second guide plate 212 can make the air flow steadily through the two parts successively, and further reduce the formation of vortex; when collecting condensed water, the water on the side wall of the air duct 100 flows smoothly into the disk body 1 through the connection part 22 successively through the arc-shaped second guide plate 212 and the inclined first guide plate 211, thereby preventing the condensed water from splashing.

[0049] The first guide plate 211 first allows the air to flow obliquely upward to the arc-shaped second guide plate 212, and then uses the condensed water to flow obliquely downward to the tray 1, see Figure 2 As shown, in this embodiment, the included angle between the second guide plate 212 and the horizontal plane is α, and the value range of α is [5°, 30°].

[0050] The above-mentioned angle range can make the air passing through the surface of the disk body 1 rise smoothly and flow to the second guide plate 212, and make the condensed water flowing from the side wall of the air duct 100 to the connecting part 22 flow smoothly into the disk body 1, and at the same time prevent the air from directly hitting the second guide plate 212 due to the above-mentioned excessive angle, aggravating the vortex problem, and preventing the condensed water from splashing out of the disk body 1.

[0051] In this embodiment, the area formed between the first guide plate 211, the second guide plate 212 and the connecting portion 22 completes the smooth reversal of the air flow and the water flow. As an optional embodiment, see Figure 2As shown, the angle between the plane where the second guide plate is located and the plane where the connecting part is located is β, and the value range of β is [100°, 130°].

[0052] The above angle range is set to facilitate the air to smoothly turn to flow along the connection part 22 after being guided by the first guide plate 211 and the second guide plate 212, and to connect the connection part 22 with the side wall of the air duct 100 to realize the air flow along the extension direction of the air duct 100; to realize the water on the side wall of the air duct 100 to smoothly flow into the tray 1, to prevent the condensed water from flowing too fast and splashing out of the tray 1. To prevent the air vortex and condensed water from not being able to smoothly flow into the tray 1 due to the angle being too small, and to prevent the angle from being too large to occupy a large space.

[0053] As an alternative embodiment, see Figure 2-Figure 4 As shown, the portion of the connection portion 22 used for connection with the side wall of the air duct 100 is parallel to the side wall of the air duct 100 connected thereto.

[0054] Preferably, the connection portion 22 is parallel to and close to the side wall of the air duct 100. The above structure is beneficial to the installation of the water receiving tray on the one hand, and on the other hand, it is beneficial for the condensed water on the side wall of the air duct 100 to flow smoothly along the connection portion 22 into the tray body 1.

[0055] As an alternative embodiment, see Figure 1-Figure 4 As shown, the connection part 22 is a flat plate and is arranged vertically.

[0056] The connection part 22 of the above structure facilitates the entire connection part 22 to be in close contact with the side wall of the air duct 100 .

[0057] like Figure 1 and Figure 2 As shown, each part of the guide assembly 2 in this embodiment is a plate-like structure, which is connected to the side wall of the air duct on the disc body and does not occupy too much space.

[0058] like Figure 1 and Figure 2 As shown in the figure, the guide component 2 is arranged on one side of the disc body 1 along the length direction of the disc body 1. In addition, in order to further reduce the generation of air vortices and further improve the ability to collect condensed water, the guide component 2 can also be arranged on multiple sides of the disc body 1 along the length direction of the disc body 1, and / or be arranged on one or more sides of the disc body 1 along the width direction of the disc body 1.

[0059] As an optional implementation, the flow guide component 2 is connected to the upper end of the side wall of the disk body 1.

[0060] The above structure facilitates the smooth reversal of air from the upper surface of the disc body 1 and facilitates the smooth entry of condensed water from the upper end of the disc body 1 into the disc body 1. The flow guide component 2 can be integrally formed with the disc body 1.

[0061] A preferred solution is that the three side surfaces of the disk body 1 are connected with the flow guide components 2 , wherein the side of the disk body 1 not connected with the flow guide component 2 is used to be arranged on the windward side of the heat exchanger 200 .

[0062] Since the space in the air duct 100 is narrow and the height of the tray 1 is relatively small, the guide components 2 arranged on the three sides of the tray 1 can more effectively prevent the water overflowing from the tray 1 from falling into the air duct 100, further improving the ability of the water receiving tray to collect condensed water and prevent air vortexes. And the guide component 2 is not arranged on the side wall of the tray 1 corresponding to the windward side of the heat exchanger 200. Figure 3 As shown, the influence of the guide component 2 on the air intake volume is prevented.

[0063] The working principle of the water receiving tray in this embodiment is as follows: Figure 3 and Figure 4 , the water receiving tray is arranged below the heat exchanger 200 to receive the condensed water on the surface of the heat exchanger 200. In addition, on the one hand, one end of the flat connecting portion 22 connected to the side wall of the air duct 100 is parallel to and in close contact with the side wall of the air duct 100. When the air passes through the surface of the tray 1 after heat exchange in the heat exchanger 200, it is guided by the guide portion 21 and smoothly turns to flow along the connecting portion 22, and then flows along the extension direction of the air duct 100. In a narrow area, the air flows in the same direction of the air duct 100, reducing eddy currents and ensuring the air volume; on the other hand, the condensed water on the surface of the heat exchanger 200 is splashed onto the side wall of the air duct 100 by the influence of the incoming wind. The connecting portion 22 is in close contact with the side wall of the air duct 100, and the condensed water on the side wall of the air duct 100 can be drained to the guide portion 21. The condensed water flows smoothly into the tray 1 through the guide portion 21, effectively collecting the condensed water while preventing the condensed water from splashing out of the tray 1.

[0064] Example 2

[0065] See also Figure 3 and Figure 4 As shown, this embodiment provides an air conditioner, which includes a cabinet and an air inlet 400, an air outlet 300, an air duct 100 and a heat exchanger 200 located in the cabinet. The heat exchanger 200 is located at the air inlet 400, and the air duct 100 is also connected to the water collecting pan in the above-mentioned embodiment 1.

[0066] The air conditioner provided in this embodiment, due to the above-mentioned water receiving tray, can smoothly guide the air passing through the water receiving tray to flow along the extension direction of the air duct 100 and then flow to the air outlet 300, which has the advantages of reducing the vortex in the air duct 100, ensuring the air output, and effectively collecting condensed water.

[0067] As an alternative embodiment, see Figure 3 and Figure 4 The flow guide component 2 is located on the air outlet side of the heat exchanger 200 .

[0068] The air guide component 2 is located at the air outlet side, does not affect the air intake volume of the air conditioner, and the air after heat exchange by the heat exchanger 200 can be guided by the air guide component 2.
