[0039] like Figures 1 to 6As shown, according to the embodiment of the utility model, the first aspect of the utility model proposes a water receiving device, the water receiving device includes a water receiving pan 20 and a water retaining assembly 30, the water receiving pan 20 is used to be arranged below the evaporator 10 to receive the condensed water generated by the evaporator 10, the water retaining assembly 30 is arranged above the water receiving pan 20, and the water retaining assembly 30 is arranged at the downwind of the evaporator 10 ( Figure 1 The middle arrow indicates the air outlet direction of the evaporator 10).

[0040] It is understandable that the evaporator 10 is the evaporator 10 in the air conditioner, and its function is to exchange heat between the low-temperature condensate and the air, and the condensate vaporizes to absorb heat from the air to achieve a cooling effect. Air is blown in from one side of the evaporator 10, and then blown out from the other side after heat exchange through the evaporator 10. The side from which the evaporator 10 blows out air is the air outlet of the evaporator 10. The evaporator 10 will produce condensed water during operation, and the condensed water will splash out of the evaporator 10 under the action of the overwind. The utility model sets a water retaining assembly 30 at the downwind side of the evaporator 10. The water retaining assembly 30 can shield the condensed water carried by the air outlet of the evaporator 10 to reduce the flying water phenomenon. The water retaining assembly 30 can be a plate-type structure, such as a rectangular plate or other plate-type structure that matches the shape of the evaporator 10. The water receiving tray 20 can refer to the existing water receiving tray 20, such as a rectangular water receiving tray 20. A pit is formed on the upper side of the water receiving tray 20 to receive the condensed water dropped from the evaporator 10. The bottom end of the water retaining assembly 30 can be connected and fixed to the water receiving tray 20 by welding or bolting. The flying water of the evaporator 10 is intercepted by the water retaining assembly 30 and flows downward under the action of gravity to the water receiving tray 20 for collection and discharge, so as to reduce the flying water phenomenon of the evaporator 10.

[0041] The utility model receives the condensed water generated by the evaporator 10 through a water receiving pan 20 disposed below the evaporator 10, and shields the condensed water blown out from the air outlet of the evaporator 10 through a water blocking assembly 30, so that the condensed water of the evaporator 10 is collected in the water receiving pan 20, thereby reducing the splashing of the condensed water of the evaporator 10, thereby reducing the accumulation of water and rust in the air-conditioning unit, thereby improving the safety and reliability of the air-conditioning unit.

[0042] like Figure 1 to Figure 2 As shown, in some embodiments of the present invention, the water retaining assembly 30 has a first projection on the projection plane, and the evaporator 10 has a second projection on the projection plane, and the first projection and the second projection at least partially overlap, wherein the projection plane is perpendicular to the horizontal plane.

[0043] It can be understood that the water retaining assembly 30 can be arranged vertically, that is, the water retaining assembly 30 extends along the height direction of the evaporator 10. Further, the water retaining assembly 30 can be arranged in parallel with the evaporator 10, and in the horizontal direction, the projection of the water retaining assembly 30 coincides with at least part of the projection of the evaporator 10, so that the flying water of the evaporator 10 can be intercepted by the water retaining assembly 30 at the air outlet end under the action of horizontal blowing, so that the flying water is then collected by the water receiving tray 20, which will not affect other electrical components of the air conditioner, thereby improving the reliability and safety of the air conditioner.

[0044] like Figures 1 to 4 As shown, in some embodiments of the present invention, the water retaining assembly 30 defines an air passage, and the air passage is used for allowing the air outlet of the evaporator 10 to pass through the water retaining assembly 30 .

[0045] It can be understood that the water retaining component 30 can be a rectangular frame structure, a plurality of through holes can be opened on the water retaining component 30, or a part of the water retaining component 30 can be a mesh structure to construct an air passage, so that the air outlet of the evaporator 10 passes through the water retaining component 30, and then is transported as cold air to the space that needs to be refrigerated. A plurality of air passages can be set on the water retaining component 30, and the air passages extend along the thickness direction of the water retaining component 30, and the cross-section of the air passages can be circular, diamond-shaped or rectangular.

[0046] like Figures 1 to 4 As shown, in some embodiments of the present invention, the water retaining assembly 30 includes at least one frame 31 and a water retaining net 32. The frame 31 is installed on the water receiving tray 20. The frame 31 encloses an air passage. The frame 31 is arranged around the outer edge of the water retaining net 32. The water retaining net 32 ​​covers the air passage.

The water retaining net 32 ​​can be a rectangular net or a multi-layer rectangular net. The hollows formed by the grid of the rectangular net can be used for passing wind. The water retaining net 32 ​​can intercept the flying water of the evaporator 10 and allow the wind from the evaporator 10 to blow through, so as to avoid the water retaining plate blocking the wind from the evaporator 10. The edge of the water retaining net 32 ​​can be fixedly installed with the frame 31 by welding or clamping, and the bottom end of the frame 31 can be fixed to the water receiving tray 20 by welding or bolts.

[0048] like Figures 1 to 4 As shown, in some embodiments of the present invention, a slot 33 is provided on one side of the frame 31 facing the air passage, and the outer edge of the water retaining net 32 ​​is inserted into the slot 33 .

[0049] It is understandable that a card slot 33 can be opened on the inner side of the frame 31, and the card slot 33 is arranged on the water retaining net 32 ​​along the outer edge of the water retaining net 32.

[0051] It is understandable that the connecting frame 40 can be a U-shaped structure, that is, the connecting frame 40 includes a top plate and two support plates, the two support plates are symmetrically arranged, and the support plates are L-shaped, the top of the support plate is welded to the top plate, the bottom of the support plate is welded to the water receiving tray 20, and the top plate is fixed to the frame 31 by fasteners, such as screws, to achieve the installation of the water baffle. A water hole can also be provided on the support plate to connect the two parts of the water receiving tank 21 located on both sides of the connecting frame 40, so as to facilitate the reception and discharge of condensed water.

[0052] like Figure 1 As shown, in some embodiments of the present invention, the water retaining net 32 ​​includes a supporting portion and a plurality of stacked filtering portions, both of which are in a mesh shape, the filtering portion is connected to the supporting portion, and the frame 31 is arranged around the outer edge of the supporting portion.

[0053] It is understandable that. The filter part can be a nylon mesh, and the filter part meets the G2 protection level. Multiple nylon meshes are stacked so that the condensed water carried by the air outlet of the evaporator 10 can be intercepted by the nylon mesh. The nylon mesh has good anti-corrosion performance and can reduce the rust of the water retaining assembly 30. The filter part can be adapted to the shape of the frame 31, that is, the filter part has a rectangular structure. The support part can be an aluminum mesh or a painted steel wire mesh, which is also adapted to the shape of the frame 31. The nylon mesh can be fixed to the support part by winding or hooking, and the outer edge of the support part is connected to the slot 33 of the frame 31 to fix the water retaining net 32.

[0054] like Figure 1 and Figure 5 As shown, in some embodiments of the utility model, a water receiving groove 21 with a top opening is formed on the water receiving tray 20, the bottom of the water retaining assembly 30 is arranged in the water receiving groove 21 or above the water receiving groove 21, the water receiving tray 20 is also provided with a drain outlet 22 connected to the water receiving groove 21, and the water receiving groove 21 is provided with an installation portion for installing the evaporator 10.

[0055] It is understandable that the water receiving tray 20 can be a tray-shaped structure, that is, the water receiving tray 20 is composed of a bottom plate and a side plate, the side plate is arranged around the bottom plate along the outer edge of the bottom plate, the bottom plate can be a rectangular plate structure, and the bottom plate and the side plate can be welded or integrally formed by injection molding. The side plate and the bottom plate define a water receiving groove 21, the opening of the water receiving groove 21 is set upward, and bolt holes can be set on the bottom plate or welded to the connecting frame 40 for connection and fixation. A drain port 22 can be opened at the bottom end of the side plate or the bottom plate to discharge the received condensed water to the outside of the water receiving tray 20. The evaporator 10 can be installed close to one side of the water receiving groove 21 along its own length direction, and the air outlet end of the evaporator 10 is arranged toward the other side of the water receiving groove 21 along its own length direction, and the water retaining assembly 30 is installed close to the middle part of the water receiving groove 21 along its own length direction, so that the condensed water carried by the air outlet of the evaporator 10 can be intercepted by the water retaining assembly 30. The length of the water receiving groove 21 can ensure that the condensed water of the air outlet of the evaporator 10 that is not intercepted by the water retaining assembly 30 is received by the water receiving groove 21, thereby further improving the safety and reliability of the air conditioner.

[0056] like Figure 1 to Figure 2 As shown, in some embodiments of the present invention, along the air outlet direction of the evaporator 10, the distance between the water retaining assembly 30 and the evaporator 10 ( Figure 2 a) is set between 150 mm and 250 mm.

[0057] It is understandable that the water retaining assembly 30 can be set at 150 mm to 250 mm away from the air outlet end of the evaporator 10 according to the designed air volume of the air conditioner indoor unit, so that the water retaining assembly 30 will not cause excessive obstruction to the air outlet, and the wind force will not have too much impact on the connection reliability of the water retaining assembly 30.

[0058] The second aspect of the utility model provides an air conditioning unit, comprising:

[0059] A water receiving device, which is the water receiving device proposed in the first aspect of the utility model;
