Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a water tray structure and a duct air conditioner. Background Technology

[0002] In air conditioners, a drip tray is usually installed at the bottom of the evaporator to collect the condensate that flows down the surface of the evaporator and to drain the collected condensate.

[0003] However, in some air conditioners, such as ducted air conditioners, due to space constraints and frame molding limitations, a grille support structure is installed between the water tray and the air inlet of the cross-flow fan. This grille support structure can lead to airflow loss and noise generation at the air inlet. Summary of the Invention

[0004] This invention provides a water tray structure and a duct air conditioner to solve the defects of existing grille support structures that cause airflow loss and noise generation at the air inlet. It guides the flowing air, ensuring all airflow enters the air inlet and maintaining sufficient airflow. Furthermore, as the air flows along the smooth curved surface, the surface reduces friction with the flowing air, preventing noise generation.

[0005] This invention provides a water receiving tray structure, comprising:

[0006] The disc body has a bottom plate and multiple side plates connected to the bottom plate. The bottom plate and the multiple side plates form a water tank, and the side plates are also provided with water outlet holes.

[0007] An air guide body is connected to a first side plate. The air guide body includes an air guide section and an extension section extending outward from the air guide section. The longitudinal contour line of the outer side wall of the air guide section is a smooth curve, and the edge of the outer side wall of the air guide section is used to overlap with the housing of the air duct machine.

[0008] According to a water receiving tray structure provided by the present invention, the inner wall of the air guide is planar, the top wall of the air guide is arc-shaped, and the inner wall, the top wall and the outer wall are smoothly transitioned.

[0009] According to a water receiving tray structure provided by the present invention, the air guide body includes two end plates and multiple protective plates, and the interior of the two end plates and multiple protective plates forms an inner cavity.

[0010] According to a water receiving tray structure provided by the present invention, the inner cavity is filled with a heat insulation material.

[0011] According to the present invention, the air guide body and the tray body are integrally formed.

[0012] The present invention provides a duct air conditioner, including a duct air conditioner housing and a water receiving tray structure as described above.

[0013] According to the present invention, the duct air conditioner housing includes a vortex tongue, an air duct is formed outside the vortex tongue, and a cavity is formed inside the vortex tongue;

[0014] The extension is disposed within the cavity.

[0015] According to the present invention, the duct air conditioner further includes a cavity containing air.

[0016] According to the present invention, the extension is disposed in the cavity on the side near the air inlet of the air duct machine.

[0017] According to a duct air conditioner provided by the present invention, an overlapping platform is provided between the air guide section and the extension section, the overlapping platform being used to overlap with the housing of the duct air conditioner.

[0018] The water receiving tray structure provided in this embodiment of the invention includes an air guide connected to the tray body. The air guide has a smooth curve along its outer side wall, and its edge overlaps with the duct housing. Based on this smooth curve, the outer side wall of the air guide forms a smooth curved surface to guide the flowing air, ensuring all airflow into the air inlet and guaranteeing sufficient air volume. Furthermore, as the air flows along this smooth curved surface, friction between the surface and the flowing air is reduced, preventing noise generation.

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

[0037] This invention provides a water collection tray structure, which can be installed at the bottom of an air conditioner or other electrical equipment to collect condensate flowing down from the surface of the evaporator or other structures, and to discharge the collected condensate in a unified manner. Figure 1 This 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 schematic diagram of the water receiving tray structure provided by the present invention. Please refer to [the diagram]. Figures 1 to 4 The following description uses the example of a water tray structure 100 installed in a ducted air conditioner.

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

[0039] The aforementioned tray 10 has a base plate 11 and multiple side plates 12 connected to the base plate 11. The base plate 11 and the multiple side plates 12 together form a water tank 13 to accommodate condensate. The side plates 12 are also provided with water outlet holes 14. In use, the condensate flowing into the water tank 13 can be discharged from the water receiving tray structure 100 through the water outlet holes 14.

[0040] For details, please see Figures 1 to 2 The multiple side panels 12 include a first side panel 121, and the aforementioned air guide 20 is connected to the first side panel 121, serving to guide airflow. Specifically, the air guide 20 includes an air guide section 21 and an extension section 22 extending outward from the air guide section 21. That is, the air guide section 21 is connected to the side and top surface of the first side panel 121, and the extension section 22 is connected to the top of the air guide section 21. The shape of the air guide section 21 obstructs the first side panel 121 to form a profile that facilitates airflow.

[0041] Specifically, Figure 5 This is a structural schematic diagram of the ductwork unit provided by the present invention, which can be seen in the following figure. Figure 1 and Figure 5 The longitudinal profile of the outer wall of the air guide section 21 is a smooth curve, and the edge of the outer wall of the air guide section 21 is designed to overlap with the duct housing 300. Based on the aforementioned smooth curve, the outer wall of the air guide section 21 forms a smooth curved surface to guide the flowing air, ensuring that all the air flows into the air inlet 340 and guaranteeing the airflow at the air inlet 340. Moreover, as the air flows along this smooth curved surface, the smooth curved surface can reduce friction with the flowing air, preventing noise generation.

[0042] The water tray structure 100 provided in this embodiment of the invention includes an air guide 20 connected to the tray body 10. The air guide 20 has a smooth curve along the longitudinal contour of its outer side wall, and the edge of the outer side wall overlaps with the duct housing 300. Based on this smooth curve, the outer side wall of the air guide 21 forms a smooth curved surface to guide the flowing air, ensuring that all the air flows into the air inlet 340 and guaranteeing the airflow at the air inlet 340. Furthermore, as the air flows along this smooth curved surface, the surface reduces friction with the flowing air, preventing noise generation.

[0043] The inner side of the aforementioned side plate 12 can be a flat surface or an inwardly inclined surface to promote the flow of condensate towards the outlet hole 14 and prevent condensate from remaining at the junction of the side plate 12 and the bottom plate 11. For example, the inner sides of the first side wall 121 and the second side wall 122 opposite to the first side wall 121 can be inwardly inclined surfaces.

[0044] In one embodiment, a groove 123 may be provided on the bottom plate 11 at the position corresponding to the water outlet 14 on the inner side of the side plate 12. The position of the water outlet 14 corresponds to the position of the groove 123, so that condensate can be collected through the groove 123 and discharged through the water outlet 14. Furthermore, an outwardly extending water outlet pipe 141 may be provided on the water outlet 14 on the side plate 12 to further control the flow direction and destination of the condensate. Moreover, the bottom plate 11 may also be an inclined structure, with the end having the groove 123 being relatively lower, to promote the flow of condensate towards the groove 123. Furthermore, the bottom plate 11 may have reinforcing ribs to strengthen its structure and guide water flow; however, this embodiment does not limit this feature.

[0045] Furthermore, the smooth curve of the aforementioned air guide 21 can be consistent with the curvature of the air duct 320 profile in the duct unit housing 300 to achieve a good air guiding effect. The air duct 320 refers to the channel inside the duct unit housing 300 used for airflow, which guides airflow. Based on this structure, the outer wall of the air guide 21 can be smoothly connected to the air inlet 340, making the outer wall of the air guide 21 part of the air duct 320. This results in a smoother air inlet profile, reduced air inlet resistance, and improved air inlet efficiency of the duct unit.

[0046] In one embodiment, the extension 22 is inserted into the vortex 310 of the duct unit housing 300. This insertion structure connects the drip tray structure 100 and the duct unit housing 300. Furthermore, the extension 22 also fills the vortex 310, allowing nearby air to enter the duct unit through the air inlet 340, preventing the space within the vortex 310 from accumulating air and obstructing airflow, thus reducing air volume. Moreover, the extension 22 also supports the vortex 310, strengthening its rigidity and thereby improving the overall structural strength of the duct unit.

[0047] It should be noted that when the water tray structure 100 is applied in a duct air conditioner, the first side plate 121 can be set on the side near the air inlet 340 of the duct air conditioner, so that the outer wall of the air guide 20 comes into contact with the flowing air, which can be used to ensure stable air supply and reduce air volume loss.

[0048] In one embodiment of the present invention, the inner wall of the air guide 20 is planar. This structure facilitates the insertion of the air guide 20 into the corresponding vortex tongue 310 through the planar inner wall. That is, there are no protrusions or curved surfaces on the inner wall of the air guide 20, which also facilitates the forming of the structure and simplifies the mold.

[0049] Moreover, the top wall of the air guide 20 is arc-shaped, and the inner side wall, top wall and outer side wall are smoothly transitioned. Through the above design, the air guide 20 is formed as a whole, which facilitates the transportation and installation of the air guide 20, and facilitates the air guide 20 to perform multiple functions such as air guiding, connecting the air duct housing 300, and filling the air duct vortex tongue 310.

[0050] In one embodiment of the present invention, the air guide 20 includes two end plates 221 and a plurality of protective plates 222, the interior of which forms an inner cavity. Specifically, the two end plates 221 of the air guide 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 section 21 can be formed by bending a single protective plate 222. This structure avoids gaps between multiple protective plates 222, resulting in a smooth shape and reducing airflow loss. The outer wall and top wall of the extension section 22 can be formed by splicing multiple protective plates 222, each of which is a long strip extending along the length of the disc body 10. This allows the multiple protective plates 222 to be spliced ​​together to match and connect with the end plates 221 at both ends to form a whole. Moreover, the multiple protective plates 222 are detachably connected, facilitating the filling of the inner cavity with necessary materials and the inspection and replacement of the materials within the inner cavity.

[0052] Furthermore, in one embodiment of the present invention, the aforementioned inner cavity is filled with a heat insulation material. The function of this heat insulation material is to isolate the hot and cold sides of the air guide 20, preventing condensation from forming on the air inlet side. For example, in this ducted air conditioner, the air guide 20 has a cooling zone and a normal temperature zone on its two sides, respectively. By adding a heat insulation material to the inner cavity of the air guide 20, heat exchange between the two sides is avoided, preventing condensation from forming on the air inlet side, and also ensuring the cooling effect of the ducted air conditioner.

[0053] Specifically, the material of the insulation can be polystyrene resin, which has excellent properties such as being lightweight, having low thermal conductivity, low water absorption, sound insulation, shock absorption, moisture resistance, and non-corrosiveness.

[0054] In one embodiment of the present invention, the air guide 20 and the disc 10 are integrally formed. The mold for this structure is easy to manufacture, 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 20 in the water receiving tray structure 100 can be made of various materials, such as plastic, metal or foam board, etc. This embodiment does not limit them.

[0056] The water tray structure 100 provided in this embodiment of the invention includes an air guide 20 connected to the tray body 10. The air guide 20 has a smooth curve along the longitudinal contour of its outer side wall, and the edge of the outer side wall overlaps with the duct housing 300. Based on this smooth curve, the outer side wall of the air guide 21 forms a smooth curved surface to guide the flowing air, ensuring that all the air flows into the air inlet 340 and guaranteeing the airflow at the air inlet 340. Furthermore, as the air flows along this smooth curved surface, the surface reduces friction with the flowing air, preventing noise generation.

[0057] Furthermore, in one embodiment of the present invention, the air guide 20 includes two end plates 221 and multiple protective plates 222, with an inner cavity formed inside the two end plates 221 and the multiple protective plates 222. Specifically, the two end plates 221 of the air guide 20 can be flat plates, and the outline of the two end plates 221 matches the vortex 310 so as to be installed inside the vortex 310. Furthermore, the outer wall of the air guide 21 can be formed by bending a single protective plate 222. This structure can avoid gaps between multiple protective plates 222, making its shape smooth and reducing airflow loss. The outer wall of the extension 22 and the top wall of the extension 22 can be formed by splicing multiple protective plates 222, wherein each protective plate 222 is elongated and extends along the length direction of the disc 10, so that the multiple protective plates 222 can be spliced ​​to match and connect with the end plates 221 at both ends to form a whole. Furthermore, the multiple protective plates 222 are detachably connected, facilitating the filling of the inner cavity with necessary materials and the inspection and replacement of the materials within the cavity. Moreover, the aforementioned inner cavity is filled with a heat insulation material. This heat insulation material serves to insulate the air guide 20 from heat exchange between the two sides. For example, in this ducted air conditioner, the air guide 20 has a cooling zone and a normal temperature zone on its two sides. By adding a heat insulation material to the inner cavity of the air guide 20, heat exchange between the two sides is avoided, ensuring the cooling effect of the ducted air conditioner.

[0058] This invention provides a duct air conditioner. Figure 5 This is a structural schematic diagram of the ductwork unit provided by the present invention. Please refer to it. Figure 5 The ducted air conditioner includes a ducted air conditioner housing 300 and any of the aforementioned drip tray structures 100. By placing the drip tray structure 100 at the bottom of the ducted air conditioner housing 300 and connecting it to the branch unit housing, the condensate flowing down from the evaporator is collected through the drip tray structure 100 and the collected condensate is discharged uniformly.

[0059] Specifically, a ducted air conditioner mainly consists of an indoor unit and an outdoor unit, interconnected by copper wires. During operation, the outdoor unit draws air into the supply duct, which connects to each room. The drawn-in air is then cooled and discharged through the supply duct. The aforementioned drip tray structure 100 can be installed in either the indoor or outdoor unit of the ducted air conditioner; this embodiment does not limit this. Taking the drip tray structure 100 being installed in the indoor unit as an example, this ducted air conditioner can return air from the bottom and exhaust air from the side to achieve temperature regulation.

[0060] Furthermore, in one embodiment of the present invention, the aforementioned ductwork housing 300 includes a vortex 310, the outer wall of which forms an air duct 320, i.e., an airflow channel, which can prevent gas from circulating within the ductwork housing 300. A cavity 330 is formed within the vortex 310, and the extension 22 of the aforementioned drip tray structure 100 is disposed within the cavity 330. Since the cavity 330 of the vortex 310 is opposite to the air inlet 340, this structure fills the inner cavity of the vortex 310, allowing nearby air to enter the ductwork unit through the air inlet 340, preventing airflow obstruction within the space of the vortex 310. Moreover, this structure connects the ductwork housing 300 and the drip tray structure 100, and also strengthens the structural strength of the vortex 310, thereby improving the overall structural strength of the ductwork unit.

[0061] Furthermore, in one embodiment of the present invention, since the presence of the vortex tongue 310 is to ensure the shape of the air duct 320 on the outer wall, based on the shape and orientation of the cavity 330 of the vortex tongue 310, a portion of the vortex tongue 310 is used to fill the water receiving tray structure 100, and another portion forms a cavity 331. Air is present in this cavity 331, and the air also has a certain heat insulation effect. Thus, through the above structure, both the rational utilization of the cavity 330 of the vortex tongue 310 and a good heat insulation effect can be achieved.

[0062] In any of the embodiments provided by the present invention, the extension 22 is disposed within the cavity 330 on the side near the air inlet 340 of the duct unit. This structure facilitates the installation and removal of the extension 22 and also improves the overall integrity of the duct unit.

[0063] In one embodiment of the present invention, an overlap platform 211 is provided between the air guide portion 21 and the extension portion 22. That is, the overlap platform 211 is formed by the air guide portion 21 protruding from the side of the extension portion 22, and is used to overlap with the duct housing 300, thereby forming a smooth curved surface on the outer surface of the air guide 20 and the duct housing 300 to guide the airflow and avoid air intake resistance. Based on the above structure, the outer wall of the air guide portion 21 can be further smoothly connected to the air inlet 340, making the outer wall of the air guide portion 21 part of the air duct 320, thereby making the air intake line smoother, eliminating air intake resistance, and further improving the air intake efficiency of the duct machine.

[0064] The ducted air conditioner provided in this embodiment of the invention features an air guide 20 connected to the tray 10 within a water tray structure 100. The air guide 20 has a smooth curve along the longitudinal profile of its outer side wall, and the edge of the outer side wall overlaps with the ducted air conditioner housing 300. Based on this smooth curve, the outer side wall of the air guide 21 forms a smooth curved surface to guide the flowing air, ensuring that all the air flows into the air inlet 340 and guaranteeing the airflow at the air inlet 340. Furthermore, as the air flows along this smooth curved surface, the surface reduces friction with the flowing air, preventing noise generation.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
