[0036] Now combined Figures 1 to 5 , various embodiments provided by the present invention are described. It should be understood that the following are merely illustrative embodiments of the present invention and do not constitute any particular limitation to the present invention.

[0037] An embodiment of the present invention provides a water receiving pan structure, which can be arranged at the bottom of an air conditioner or other electrical equipment to collect condensed water flowing from the surface of other structures such as an evaporator, and discharge the collected condensed water in a unified manner. Figure 1 It is one of the structural schematic diagrams of the water receiving tray structure provided by the present invention; Figure 2 This is the second structural schematic diagram of the water receiving tray structure provided by the present invention; Figure 3 This is the third structural schematic diagram of the water receiving tray structure provided by the present invention; Figure 4 This is the fourth structural diagram of the water receiving tray structure provided by the present invention, please refer to Figures 1 to 4 The following description will be made by taking the water receiving tray structure 100 disposed in a duct machine as an example.

[0038] The water receiving tray structure 100 includes a tray body 10 and an air guide body 20 connected to the tray body 10 .

[0039] The tray body 10 comprises a bottom plate 11 and a plurality of side plates 12 connected to the bottom plate 11. The bottom plate 11 and the plurality of side plates 12 together form a water tank 13 to contain condensed water. The side plates 12 are also provided with water outlets 14. In use, the condensed water flowing into the water tank 13 can be discharged from the water receiving tray structure 100 through the water outlets 14.

[0040] For details, see Figure 1 to Figure 2 The plurality of side panels 12 include a first side panel 121, and the air guide body 20 is connected to the first side panel 121 to guide the air. Specifically, the air guide body 20 includes an air guide portion 21 and an extension portion 22 extending outward from the air guide portion 21, that is, the air guide portion 21 is connected to the side surface and the top surface of the first side panel 121, and the extension portion 22 is connected to the top of the air guide portion 21. The first side panel 121 is shielded by the shape of the air guide portion 21, so as to form a profile that is conducive to air flow.

[0041] Specifically, Figure 5 This is a schematic diagram of the structure of the duct machine provided by the present invention, which can be seen in Figure 1 and Figure 5 The longitudinal contour line of the outer wall of the air guide portion 21 is a smooth curve, and the edge of the outer wall of the air guide portion 21 is used to overlap with the air duct housing 300. Based on the above-mentioned smooth curve, the outer wall of the air guide portion 21 forms a smooth curved surface to guide the flowing air so that all the air flows into the air inlet 340, thereby ensuring the air volume of the air inlet 340. Moreover, in the process of air flowing along the smooth curved surface, the smooth curved surface can reduce the friction between the air and the flowing air, thereby preventing the generation of noise.

[0042] The water receiving tray structure 100 provided in the embodiment of the present invention is provided with an air guide body 20 connected to the tray body 10 in the water receiving tray structure 100, and in the air guide body 20, the longitudinal contour line of the outer wall of the air guide portion 21 is a smooth curve, and the edge of the outer wall of the air guide portion 21 is used to overlap with the air duct housing 300. Based on the above-mentioned smooth curve, the outer wall of the air guide portion 21 forms a smooth curved surface to guide the flowing air so that all the air flows into the air inlet 340, thereby ensuring the air volume of the air inlet 340. Moreover, in the process of air flowing along the smooth curved surface, the smooth curved surface can reduce the friction between the air and the flowing air, thereby preventing the generation of noise.

[0043] The inner side of the side plate 12 may be a plane or an inwardly inclined surface to promote the condensed water to flow toward the water outlet 14 and prevent the condensed water from being retained at the junction of the side plate 12 and the bottom plate 11. For example, the inner side of the first side wall 121 and the second side wall 122 opposite to the first side wall 121 may be an inwardly inclined surface.

[0044] In one embodiment, a groove 123 may be provided on the inner side of the side panel 12 at a position corresponding to the water outlet 14 on the bottom plate 11, and the position of the water outlet 14 corresponds to the position of the groove 123, so that condensed water can be collected through the groove 123 and then discharged through the water outlet 14. Moreover, the water outlet 14 on the side panel 12 may also be provided with an outwardly extending water outlet pipe 141, etc., so as to further control the flow direction and destination of the condensed water. Moreover, the bottom plate 11 may also be an inclined structure, with one end of the groove 123 being relatively low, so as to promote the flow of condensed water to the position of the groove 123. Furthermore, the bottom plate 11 may have reinforcing ribs, etc., which can strengthen the structure of the bottom plate 11 and divert water, and this embodiment does not limit this.

[0045] Moreover, the smooth curve of the air guide portion 21 can be consistent with the curve of the air duct 320 in the air duct housing 300, so as to have a good air guiding effect. The air duct 320 refers to a channel for air flow inside the air duct housing 300, which has an air flow guiding function. Based on the above structure, the outer wall of the air guide portion 21 can be smoothly connected to the air inlet 340, so that the outer wall of the air guide portion 21 becomes a part of the air duct 320, thereby making the air inlet line smoother, reducing the air inlet resistance, and improving the air inlet efficiency of the air duct.

[0046] In one embodiment, the extension 22 is used to be inserted into the vortex tongue 310 of the air duct housing 300. Through this plug-in structure, the water tray structure 100 and the air duct housing 300 can be connected. In addition, the extension 22 also has the function of filling the vortex tongue 310, so that the air sucked nearby can enter the interior of the air duct along the air inlet 340, preventing the space in the vortex tongue 310 from accommodating air and hindering air flow, thereby reducing air volume. In addition, the extension 22 also has the function of supporting the vortex tongue 310, strengthening the strength of the vortex tongue 310, thereby improving the overall structural strength of the air duct.

[0047] It should be noted that when the water receiving tray structure 100 is used in an air duct machine, the first side panel 121 can be used to be arranged on a side close to the air inlet 340 of the air duct machine so that the outer wall of the air guide body 20 is in contact with the flowing air, which can be used to ensure smooth air supply and reduce air volume loss.

[0048] In one embodiment provided by the present invention, the inner side wall of the air guide body 20 is planar, and this structure is conducive to inserting the air guide body 20 into the corresponding vortex tongue 310 through the planar inner side wall. In other words, there is no protrusion or curved surface on the inner side wall of the air guide body 20, which also facilitates the molding of the structure and simplifies the mold.

[0049] Moreover, the top wall of the air guide body 20 is arc-shaped, and there is a smooth transition between the inner wall, the top wall and the outer wall. Through the above design, the air guide body 20 forms a whole, which is convenient for the transportation and installation of the air guide body 20, and for the air guide body 20 to play multiple roles such as guiding air, connecting the air duct machine housing 300, and filling the air duct machine vortex tongue 310.

[0050] In one embodiment provided by the present invention, the air guide body 20 includes two end plates 221 and a plurality of guard plates 222, and an inner cavity is formed inside the two end plates 221 and the plurality of guard plates 222. Specifically, the two end plates 221 of the air guide body 20 can be flat plates, and the contours of the two end plates 221 match the vortex tongue 310 so as to be installed inside the vortex tongue 310.

[0051] Furthermore, the outer wall of the air guide portion 21 can be formed by bending a protective plate 222. This structure can avoid gaps between multiple protective plates 222, making its appearance smooth and reducing air volume loss. The outer wall of the extension portion 22 and the top wall of the extension portion 22 can be formed by splicing multiple protective plates 222, wherein each protective plate 222 is in the shape of a long strip and extends along the length direction of the disk body 10, so that multiple protective plates 222 can be matched and connected with the end plates 221 at both ends to form a whole through splicing. Moreover, multiple protective plates 222 are also detachably connected together, which is convenient for filling the required substances into the inner cavity and inspecting and replacing the substances in the inner cavity.

[0052] Furthermore, in an embodiment provided by the present invention, the inner cavity is filled with a heat insulator. The function of the heat insulator is to isolate the cold and heat on both sides of the air guide 20 to prevent condensation from being generated on the air inlet side. For example, in the duct air conditioner, the two sides of the air guide 20 are a refrigeration zone and a normal temperature zone, respectively. By adding a heat insulator to the inner cavity of the air guide 20, heat exchange on both sides is avoided, condensation is prevented from being generated on the air inlet side, and the refrigeration effect of the duct air conditioner is also ensured.

[0053] Specifically, the material of the heat insulator can be polystyrene resin, which has excellent properties such as light weight, low thermal conductivity, low water absorption, sound insulation, shock resistance, moisture resistance, and non-corrosion.

[0054] In an embodiment provided by the present invention, the air guide body 20 and the tray body 10 are an integrally formed structure. The mold of this structure is easy to make, and the forming process of this structure is simple, avoiding multiple mold opening and assembly steps.

[0055] The tray body 10 and the air guide body 20 in the water receiving tray structure 100 can be made of a variety of materials, such as plastic, metal or foam board, etc., which is not limited in this embodiment.

[0056] The water receiving tray structure 100 provided in the embodiment of the present invention is provided with an air guide body 20 connected to the tray body 10 in the water receiving tray structure 100, and in the air guide body 20, the longitudinal contour line of the outer wall of the air guide portion 21 is a smooth curve, and the edge of the outer wall of the air guide portion 21 is used to overlap with the air duct housing 300. Based on the above-mentioned smooth curve, the outer wall of the air guide portion 21 forms a smooth curved surface to guide the flowing air so that all the air flows into the air inlet 340, thereby ensuring the air volume of the air inlet 340. Moreover, in the process of air flowing along the smooth curved surface, the smooth curved surface can reduce the friction between the air and the flowing air, thereby preventing the generation of noise.

[0057] Further, in an embodiment provided by the present invention, the air guide body 20 includes two end plates 221 and a plurality of guard plates 222, and the two end plates 221 and the plurality of guard plates 222 form an inner cavity. Specifically, the two end plates 221 of the air guide body 20 can be flat plates, and the contours of the two end plates 221 match the vortex tongue 310 so as to be installed inside the vortex tongue 310. Further, for the outer side wall of the air guide portion 21, it can be formed by bending a guard plate 222. This structure can avoid gaps between multiple guard plates 222, make its appearance smooth, and reduce air volume loss. For the outer side wall of the extension portion 22 and the top wall of the extension portion 22, it can be formed by splicing multiple guard plates 222, wherein each guard plate 222 is in the shape of a long strip and extends along the length direction of the disk body 10, so that the multiple guard plates 222 can be matched with the end plates 221 at both ends and connected to form a whole through splicing. Moreover, the plurality of protective plates 222 are also detachably connected together, which is convenient for filling the inner cavity with the required materials and for inspecting and replacing the materials in the inner cavity. Furthermore, the inner cavity is filled with a heat insulator. The function of the heat insulator is to isolate the cold and heat on both sides of the air guide 20. For example, in the duct air conditioner, the two sides of the air guide 20 are a refrigeration zone and a normal temperature zone, respectively. By adding a heat insulator to the inner cavity of the air guide 20, heat exchange on both sides is avoided, thereby ensuring the refrigeration effect of the duct air conditioner.

[0058] The present invention provides a duct machine. Figure 5 This is a schematic diagram of the structure of the duct machine provided by the present invention, see Figure 5 The duct machine comprises a duct machine housing 300 and any of the above-mentioned water receiving tray structures 100. By arranging the water receiving tray structure 100 at the bottom of the duct machine housing 300 and connecting it to the branch machine housing, the condensed water flowing down from the evaporator can be received by the water receiving tray structure 100 and the collected condensed water can be discharged uniformly.

[0059] Specifically, the duct machine is a duct air conditioner, which mainly includes two parts, an indoor unit and an outdoor unit, which are interconnected by copper wires. When the duct machine is running, the outdoor unit draws air into the air supply duct, and the air supply duct connects each room. Then, the drawn air is cooled and sent out through the air supply duct. Among them, the above-mentioned water receiving tray structure 100 can be set in the indoor unit or outdoor unit of the duct machine, and this embodiment does not limit this. Taking the water receiving tray structure 100 as an example that it can be set in the indoor unit of the duct machine, the duct machine can return air from the bottom and discharge air from the side to complete the temperature regulation function.

[0060] Further, in an embodiment provided by the present invention, the above-mentioned air duct housing 300 includes a vortex tongue 310, and the outer wall of the vortex tongue 310 forms an air duct 320, that is, an air flow channel, which can prevent the gas from circulating in the air duct housing 300. A cavity 330 is formed in the vortex tongue 310, and the extension portion 22 of the above-mentioned water receiving tray structure 100 is arranged in the cavity 330. Since the cavity 330 of the vortex tongue 310 is opposite to the air inlet 340, through this structure, the inner cavity of the vortex tongue 310 is filled, so that the air sucked nearby can enter the air duct machine along the air inlet 340, and the space in the vortex tongue 310 is prevented from blocking the wind. Moreover, this structure connects the air duct housing 300 and the water receiving tray structure 100, and also strengthens the structural strength of the vortex tongue 310, thereby improving the overall structural strength of the air duct machine.

[0061] Furthermore, in an embodiment provided by the present invention, since the existence of the vortex tongue 310 is to ensure the shape of the air duct 320 of the outer wall, based on the shape and orientation of the cavity 330 of the vortex tongue 310, a part of the vortex tongue 310 is used to fill the water receiving tray structure 100, and the other part forms a cavity 331. There is air in the cavity 331, and the air also has a certain heat insulation effect. Therefore, through the above structure, both the reasonable utilization of the cavity 330 of the vortex tongue 310 and a good heat insulation effect can be achieved.

[0062] In any of the above embodiments provided by the present invention, the extension part 22 is arranged on one side of the cavity 330 close to the air inlet 340 of the air duct machine. With this structure, the installation and removal of the extension part 22 are facilitated, and the integrity of the air duct machine can be improved.

[0063] In one embodiment provided by the present invention, a lap joint 211 is provided between the air guide 21 and the extension 22, that is, the lap joint 211 is formed by the side of the air guide 21 protruding from the extension 22, and is used to overlap with the air duct housing 300, so as to form a smooth curved surface on the outer side of the air guide 20 and the air duct housing 300, so as to guide the flow of air and avoid the generation of air intake resistance. Based on the above structure, the outer side wall of the air guide 21 can be further smoothly connected with the air inlet 340, so that the outer side wall of the air guide 21 becomes a part of the air duct 320, so as to make the air intake line smoother, eliminate the air intake resistance, and further improve the air intake efficiency of the air duct.

[0064] The duct air conditioner provided in the embodiment of the present invention is provided with an air guide body 20 connected to the tray body 10 in the water receiving tray structure 100, and in the air guide body 20, the longitudinal contour line of the outer wall of the air guide portion 21 is a smooth curve, and the edge of the outer wall of the air guide portion 21 is used to overlap with the duct air conditioner housing 300. Based on the above-mentioned smooth curve, the outer wall of the air guide portion 21 forms a smooth curved surface to guide the flowing air so that all the air flows into the air inlet 340, thereby ensuring the air volume of the air inlet 340. Moreover, in the process of air flowing along the smooth curved surface, the smooth curved surface can reduce the friction between the air and the flowing air, thereby preventing the generation of noise.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
