Description

Technical Field

[0001] The present application relates to the field of air-conditioning technology, for example, to a double-layer water tray assembly and an air-conditioning indoor unit. Background Art

[0002] The indoor unit of an air conditioner typically consists of a housing, a heat exchanger, and a fan. The housing is equipped with an air inlet and an air outlet. Indoor air enters through the inlet, exchanges heat with the heat exchanger, and is then blown out through the outlet. This allows the air conditioner to regulate the temperature or humidity in the user's room.

[0003] When an air conditioner indoor unit regulates the temperature or humidity in a user's room, condensation water is easily generated on the heat exchanger. Typically, a water receiving pan is provided to collect the condensation water to prevent it from flowing directly into the user's room.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] When the air inlet of the housing of the air conditioner indoor unit is set on the bottom shell, the water receiving tray set at the bottom of the heat exchanger will block the air inlet, thus reducing the air intake at the air inlet and further reducing the heat exchange capacity of the heat exchanger.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Utility Model Content

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0009] In some embodiments, a double-layer water receiving tray assembly includes: a first water receiving portion, including a first water receiving trough portion and a first raised portion protruding from the first water receiving trough portion, the first raised portion being provided with a plurality of air holes; a second water receiving portion, covering the first raised portion, and having an air gap between the second water receiving portion and the plurality of air holes, so that the wind flowing in from the air holes can flow out through the air gap.

[0010] When the air inlet of the air conditioner indoor unit is located in the bottom housing, a bottom-intake air intake mode is formed. When indoor air enters through the bottom air inlet, it can flow through the air holes of the first water receiving portion and through the air gap to the heat exchanger, where it exchanges heat. As can be seen, the double-layer water tray assembly provided in the embodiments of the present disclosure, when the air inlet is located in the lower portion of the air conditioner indoor unit housing, does not block the incoming air, thereby ensuring the heat exchange capacity of the heat exchanger.

[0011] In some optional embodiments, the first raised portion includes a platform portion and a connecting plate portion connected between the platform portion and the first water receiving trough portion, wherein the air hole is provided at one end of the connecting plate portion close to the platform portion.

[0013] In some optional embodiments, the first water receiving trough portion includes a main water receiving portion, a first water collecting portion and a second water collecting portion, the first water collecting portion is connected to the first end of the main water receiving portion, and the second water collecting portion is connected to the second end of the main water receiving portion, and the main water receiving portion includes a first water receiving bottom surface, the first water collecting portion includes a first water collecting bottom surface, and the second water collecting portion includes a second water collecting bottom surface, wherein the first water collecting bottom surface is lower than the first water receiving bottom surface; and / or the second water collecting bottom surface is lower than the first water receiving bottom surface.

[0014] In some optional embodiments, the main water receiving part includes a first water tank located on one side of the first connecting inclined plate, and a second water tank located on one side of the second connecting inclined plate; the second water receiving part includes a first side edge located on one side of the first connecting inclined plate, and a second side edge located on one side of the second connecting inclined plate, wherein the first side edge is arranged between the first water tank and the platform part, and the second side edge is arranged between the second water tank and the platform part.

[0015] In some optional embodiments, the first water receiving part also includes a plurality of screw columns protruding from the first water receiving trough part, the screw columns are arranged on the side of the first raised part, and the side of the second water receiving part is provided with a plurality of connection holes corresponding to the screw columns.

[0016] In some optional embodiments, the first water receiving portion and the second water receiving portion are integrally formed.

[0017] In some embodiments, an air conditioner indoor unit includes an indoor unit body, wherein the indoor unit body includes the double-layer water receiving tray assembly as described above.

[0018] In some optional embodiments, the indoor unit body also includes a heat exchanger, which is arranged on the upper part of the second water receiving part, wherein the length of the first protrusion is less than or equal to the length of the second water receiving part; and / or the length of the heat exchanger is less than or equal to the length of the second water receiving part.

The second water receiving portion is provided overlying the first raised portion and having an air gap between the second water receiving portion and the plurality of air holes.

[0022] When the air inlet of the air conditioner indoor unit is set below the water tray, the water tray blocks the air inlet, thereby reducing the air intake at the air inlet. The evaporator of the air conditioner indoor unit is mostly set in an inverted V shape. The lowest point of the evaporator is severely blocked by the water tray, and the wind cannot pass through, resulting in low heat exchange efficiency, thereby affecting the heat exchange capacity of the entire machine.

[0023] The double-layer water collecting pan assembly provided in the embodiment of the present disclosure allows the air entering from the air inlet to pass through the air holes of the first raised portion and then flow through the heat exchanger, thereby avoiding the problem of the water collecting pan blocking the air inlet and reducing the air intake volume, thereby ensuring the heat exchange capacity of the heat exchanger.

[0024] The above general description and the following description are exemplary and explanatory only and are not intended to limit the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] An embodiment of the present disclosure provides a double-layer water tray assembly.

[0048] Optionally, the double-layer water receiving tray assembly includes a first water receiving portion 1 and a second water receiving portion 2. The first water receiving portion 1 includes a first water receiving trough portion and a first raised portion protruding from the first water receiving trough portion, the first raised portion being provided with a plurality of air holes 101; the second water receiving portion 2 is overlying the first raised portion, and a wind gap is provided between the second water receiving portion 2 and the plurality of air holes 101, so that air flowing in from the air holes 101 can flow out through the wind gap.

[0049] The first raised portion of the first water receiving portion 1 protrudes from the first water receiving trough portion, so that in the vertical height direction, the height of the first raised portion is higher than the height of the first water receiving trough portion. The first raised portion is provided with a plurality of air holes 101. Optionally, the air holes 101 pass through the first raised portion.

[0050] The second water receiving portion 2 is disposed above the first raised portion and is generally shaped to cover the first raised portion. Optionally, when projected vertically, a first projection of the second water receiving portion 2 covers a second projection of the first raised portion. Optionally, the second water receiving portion 2 can be used to securely connect the heat exchanger 4.

[0051] A wind gap is provided between the second water receiving portion 2 and the wind hole 101. It is understandable that the wind gap is connected to the wind hole 101. In this way, the wind passing through the wind hole 101 can continue to flow out through the wind gap.

[0052] The double-layer water tray assembly provided in the embodiments of the present disclosure can be applied to the following air conditioner indoor units.

[0053] The air conditioner indoor unit includes a housing and a heat exchanger 4 and a fan 5 disposed therein. A double-layer water receiving tray assembly is disposed below the heat exchanger 4. The housing is provided with an air inlet 31 and an air outlet 32, and the air inlet 31 is disposed on the bottom shell, thus forming a bottom air intake mode. When indoor air enters from the lower air inlet 31, it can flow through the air holes 101 of the first water receiving part 1 and flow through the wind gap to the heat exchanger 4 to exchange heat with the heat exchanger 4. Figure 7 As shown by the arrow in the figure, the double-layer water receiving tray assembly provided in the embodiment of the present disclosure does not block the incoming air when the air inlet 31 is disposed at the lower portion of the housing of the air conditioner indoor unit, thereby ensuring the heat exchange capacity of the heat exchanger 4.

[0054] Optionally, the shape of the air hole 101 may be circular, polygonal or other irregular shapes. The embodiment of the present disclosure does not impose too many restrictions on the shape of the air hole 101.

[0055] Optionally, the inner diameter of the air hole 101 is less than or equal to 10 mm.

[0056] Optionally, a plurality of air holes 101 are evenly arranged along a preset straight line on the first raised portion, such as Figures 3 to 5 As shown; or, a plurality of air holes 101 are arranged in an array on the first raised portion.

[0057] Optionally, the first raised portion includes a platform portion 111 and a connecting plate portion. The connecting plate portion is connected between the platform portion 111 and the first water receiving trough portion. The air hole 101 is provided at one end of the connecting plate portion close to the platform portion 111.

[0058] Air hole 101 is located at one end of the connecting plate portion, near platform portion 111. That is, air hole 101 is positioned at a higher position on the connecting plate portion. This allows for a certain amount of condensed water to be absorbed by first water receiving portion 1 without obstructing or clogging air hole 101. Furthermore, the elevated position of air hole 101 increases the amount of water received by first water receiving portion 1, preventing condensed water from overflowing from air hole 101.

[0059] Optionally, the connecting plate portion includes a first connecting inclined plate 112 and a second connecting inclined plate 113 respectively connected to both sides of the platform portion 111. Figure 4 As shown. Moreover, the distance between the first connecting inclined plate 112 and the second connecting inclined plate 113 near one end of the first water receiving trough portion is a first distance H1, and the distance between the first connecting inclined plate 112 and the second connecting inclined plate 113 near one end of the platform portion 111 is a second distance H2, wherein the first distance H1 is greater than the second distance H2. Figure 5 shown.

[0060] In the disclosed embodiment, the first spacing H1 formed by the first connecting slanted plate 112 and the second connecting slanted plate 113 is greater than the second spacing H2, that is, the first raised portion is roughly in the shape of a boss that is wider at the bottom and narrower at the top. This increases the air intake at the first spacing H1, increases the heat exchange capacity of the heat exchanger 4, and thus improves the heat exchange capacity of the heat exchanger 4.

[0061] Optionally, the inclination angle of the first connecting inclined plate 112 is the same as the inclination angle of the second connecting inclined plate 113 .

[0062] Optionally, the first connecting inclined plate 112 is provided with a first row of air holes, the first row of air holes including a plurality of air holes 101, and the second connecting inclined plate 113 is provided with a second row of air holes, the second row of air holes including a plurality of air holes 101. The plurality of air holes 101 in the first row of air holes are arranged correspondingly to the plurality of air holes 101 in the second row of air holes. Optionally, the arrangement height of the air holes in the first row is equal to the arrangement height of the air holes in the second row.

[0063] Optionally, the first water receiving trough portion includes a main water receiving portion, a first water collecting portion 12 and a second water collecting portion 13, the first water collecting portion 12 is connected to the first end of the main water receiving portion, the second water collecting portion 13 is connected to the second end of the main water receiving portion, and the main water receiving portion includes a first water receiving bottom surface, the first water collecting portion 12 includes a first water collecting bottom surface, and the second water collecting portion 13 includes a second water collecting bottom surface, wherein the first water collecting bottom surface is lower than the first water receiving bottom surface; and / or the second water collecting bottom surface is lower than the first water receiving bottom surface. Figure 3 shown.

[0064] The first water collecting part 12 and the second water collecting part 13 are respectively provided at both ends of the main water receiving part. Moreover, the first water collecting bottom surface of the first water collecting part 12 is lower than the first water receiving bottom surface, and the second water collecting bottom surface of the second water collecting part 13 is lower than the first water receiving bottom surface. In this way, the condensed water flowing into the main water receiving part can flow to the first water collecting part 12 or the second water collecting part 13 under the action of gravity. The double-layer water receiving tray assembly provided by the embodiment of the present disclosure increases the amount of condensed water received while preventing the condensed water from blocking the air hole 101 and preventing the condensed water from overflowing from the air hole 101.

[0065] Optionally, the main water receiving portion is arranged along the length, while the first water collecting portion 12 and the second water collecting portion 13 are arranged along the width. The main water receiving portion, the first water collecting portion 12, and the second water collecting portion 13 generally form an "I" shape. Optionally, the volume of the first water collecting portion 12 is greater than or equal to the volume of the second water collecting portion 13. Optionally, the volume of the first water collecting portion 12 and the second water collecting portion 13 can be adjusted based on the internal space size of the air conditioner indoor unit.

[0066] Optionally, the main water receiving portion includes a first water tank 114 located on one side of the first connecting inclined plate 112, and a second water tank 115 located on one side of the second connecting inclined plate 113. Figure 5 As shown; the second water receiving portion 2 includes a first side 21 located on one side of the first connecting inclined plate 112, and a second side 22 located on one side of the second connecting inclined plate 113, wherein the first side 21 is arranged between the first water tank 114 and the platform portion 111, and the second side 22 is arranged between the second water tank 115 and the platform portion 111. Figure 2 shown.

[0067] The first water tank 114 and the second water tank 115 are substantially in the shape of a long strip. The platform portion 111 includes a first platform edge and a second platform edge, wherein the first platform edge is located on one side of the first water tank 114 and the second platform edge is located on one side of the second water tank 115.

[0068] The first side 21 is disposed between the first water tank 114 and the platform 111. This means that the first side 21 is disposed between the outer edge of the first water tank 114 and the edge of the first platform. This allows condensed water flowing down the first side 21 to flow smoothly into the first water tank 114.

[0069] Similarly, the second side edge 22 is disposed between the second water tank 115 and the platform portion 111. This means that the second side edge 22 is disposed between the outer edge of the second water tank 115 and the edge of the second platform portion. This allows condensed water flowing down the second side edge 22 to flow smoothly into the second water tank 115.

[0070] Optionally, the side of the first water tank 114 is stepped, and similarly, the side of the second water tank 115 is stepped. Figure 6 and Figure 7 To improve the water collection efficiency of the first and second water tanks 114, 115 and to prevent water from overflowing from the first and second water tanks 114, 115, the first and second water tanks 114, 115 are designed in a stepped configuration. This improves the water collection stability of the first and second water tanks 114, 115 and prevents the condensed water from sloshing around in the tanks.

[0071] When the condensed water at the lower end of the heat exchanger 4 drips onto the second water receiving portion 2, a small portion of the condensed water may flow along the lower surface of the second water receiving portion 2, thereby causing water leakage in the air conditioner indoor unit, seriously affecting the user experience. In the embodiment of the present disclosure, the first side 21 is provided with a water flow guide facing the first water tank 114, and the second side 22 is provided with a water flow guide facing the second water tank 115. Figure 6 and Figure 7 In this way, the stability of the condensed water flowing from the first side 21 to the first water tank 114 is improved, and the stability of the condensed water flowing from the second side 22 to the second water tank 115 is also improved.

[0072] Optionally, the first water receiving portion 1 further includes a plurality of screw columns 116 protruding from the first water receiving groove portion, the screw columns 116 are arranged on the side of the first protruding portion, and the side of the second water receiving portion 2 is provided with a plurality of connection holes 23 corresponding to the screw columns 116. Figure 2 and Figure 4 shown.

[0073] The first water receiving part 1 and the second water receiving part 2 can be connected by screw connection. At this time, the first water receiving part 1 is located at the bottom, and the second water receiving part 2 is connected to the upper part of the first water receiving part 1. The first water receiving part 1 and the second water receiving part 2 are detachably connected.

[0074] Optionally, the first water tank 114 is provided with a plurality of spaced screw posts 116, and the second water tank 115 is provided with a plurality of spaced screw posts 116. A plurality of connection holes 23 are correspondingly provided on the two sides of the second water receiving portion 2. This improves the connection stability between the first water receiving portion 1 and the second water receiving portion 2.

[0075] Optionally, the first water receiving portion 1 and the second water receiving portion 2 are integrally formed.

[0076] The first water receiving portion 1 and the second water receiving portion 2 can also be integrally formed. This simplifies the manufacturing process of the double-layer water receiving tray assembly, reduces costs, and also improves the structural stability of the double-layer water receiving tray assembly.

[0077] The embodiment of the present disclosure also provides an air conditioner indoor unit.

[0078] Optionally, the air conditioner indoor unit includes an indoor unit body, and the indoor unit body includes the aforementioned double-layer water receiving tray assembly.

[0079] The heat exchanger 4 is disposed above the second water receiving portion 2. The first raised portion of the first water receiving portion 1 is provided with a plurality of air holes 101. Furthermore, an air gap is provided between the second water receiving portion 2 and the first water receiving portion 1, and the air gap is connected to the air holes 101. Thus, when the air inlet 31 of the air conditioner indoor unit is located at the bottom, air entering through the bottom air inlet 31 can flow through the air holes 101 and the air gap to the bottom of the heat exchanger 4, facilitating heat exchange at the bottom of the heat exchanger 4. This avoids the problem of reduced heat exchange capacity of the heat exchanger 4 caused by the water receiving pan blocking the air inlet 31, thereby improving the heat exchange capacity of the heat exchanger 4.

[0080] Optionally, the indoor unit body also includes a heat exchanger 4, which is arranged on the upper part of the second water receiving part 2, wherein the length of the first protrusion is less than or equal to the length of the second water receiving part 2; and / or the length of the heat exchanger 4 is less than or equal to the length of the second water receiving part 2.

[0081] The heat exchanger 4 is arranged on the upper part of the second water receiving part 2. In the embodiment of the present disclosure, the length of the heat exchanger 4 is less than or equal to the length of the second water receiving part 2. In this way, along the length direction, the heat exchanger 4 can be completely fixed to the second water receiving part 2, which improves the installation stability of the second water receiving part 2 on the heat exchanger 4. The length of the second water receiving part 2 is greater than or equal to the length of the first protrusion. In this way, the effect of the second water receiving part 2 on receiving the condensed water on the heat exchanger 4 is improved. The length direction of the heat exchanger 4, the second water receiving part 2 and the first protrusion is Figure 1 Indicated by the arrow direction.

[0082] Optionally, the air-conditioning indoor unit further includes a TV cabinet with an accommodating cavity provided inside, wherein the indoor unit body is arranged in the accommodating cavity.

[0083] An embodiment of the present disclosure provides a TV cabinet air conditioner.

[0084] As people's living standards improve, they have increasingly higher requirements for the integration of home appliances and furniture. The disclosed embodiments provide a TV cabinet air conditioner with an indoor unit embedded within the TV cabinet, which effectively utilizes the user's indoor space while improving the integration of the air conditioner indoor unit and the TV cabinet.

[0085] The air outlet 32 of the TV cabinet air conditioner is arranged on the upper part of the side panel, and the overall air outlet height is relatively low. In this way, when the air conditioner is in heating mode, the hot air is blown to the floor of the user's room, which is more conducive to the sinking of the hot air and improves the heating effect of the air conditioner.

[0086] Optionally, the air conditioner indoor unit further comprises an air inlet 31, wherein a filter is provided at the air inlet 31 to reduce dust or other debris from entering the housing of the air conditioner indoor unit. Optionally, the filter is further provided with a brush cleaning assembly to regularly clean the dust deposited on the filter.
