It is to be understood that, although directional terms, such as "front", "rear", "upper", "lower", "left", "right", "top", "bottom", etc., may be used in this application to describe various example structural portions and elements of the present application, these terms are used herein for convenience of description only and are determined based on the example orientations shown in the drawings.

Fig. 1A to 1D illustrate an embodiment of a water-receiving tray according to the present application, for illustrating a specific structure of the water-receiving tray 100, wherein fig. 1A is a perspective structural view of the water-receiving tray 100 from a front side, fig. 1B is a perspective structural view of the water-receiving tray 100 from a rear side, fig. 1C is a side view of the water-receiving tray 100, and fig. 1D is a front view of the water-receiving tray 100. As shown in fig. 1A-1D, the drip tray 100 includes a chassis 101, and a water deflector 156 surrounding the chassis 101 and connected above the edge of the chassis 101, the top edge of the water deflector 156 being flush to form a top opening 155 at the top of the drip tray 100. In this embodiment, the top opening 155 is a rectangular opening. The top opening 155 is for receiving condensate dripping from the unit and the water deflector 156 is for blocking the outflow of condensate from the rim of the pan 101. In this embodiment, the chassis 101 and the water blocking device 156 are formed by integrally bending a stainless steel sheet, and then are connected by a welding process. As an example, the copper content in the stainless steel sheet is greater than or equal to 1.5% so that the drip tray 100 has an antimicrobial effect, such as effective inhibition or killing of E.coli, staphylococcus aureus, and the like.

Specifically, the water deflector 156 includes a first side wall 111, a second side wall 112, a first end wall 113, and a second end wall 114. The bottom edges of the first side wall 111 and the second side wall 112 are connected to opposite sides in the width direction W of the chassis 101, and the bottom edges of the first end wall 113 and the second end wall 114 are connected to opposite sides in the length direction L of the chassis 101. And the first side wall 111, the second side wall 112, the first end wall 113, and the second end wall 114 are connected to each other to form a water blocking device 156 to close the chassis 101 in the circumferential direction of the chassis 101 and to form a top opening 155 above the chassis 101. As one example, the first side wall 111, the second side wall 112, the first end wall 113, and the second end wall 114 extend generally vertically upward from an edge of the chassis 101. The first end wall 113 has a height in the vertical direction that is greater than the height of the second end wall 114. And the heights of the first and second side walls 111 and 112 gradually increase in a direction from the second end wall 114 to the first end wall 113 (i.e., a right-to-left direction in fig. 1C). That is, the bottom tray 101 is gradually inclined downward from right to left while the top edges of the respective side walls and end walls of the water deflector 156 are at the same height.

The drip tray 100 further includes a first side wall support wall 115, a second side wall support wall 116, a first end wall support wall 117, and a second end wall support wall 118, the first side wall support wall 115, the second side wall support wall 116, the first end wall support wall 117, and the second end wall support wall 118 being connected to top edges of the first side wall 111, the second side wall 112, the first end wall 113, and the second end wall 114, respectively, and being formed by bending outwardly from the respective top edges. In this embodiment, the top edges of each side wall, end wall, and each support wall are all on the same mounting plane α that is flush with the bottom of the unit so that the drip tray 100 can be connected to the bottom of the unit through each support wall so that the top opening 155 can receive condensate that drips from the unit. With the top edges of the respective side and end walls lying on the same mounting plane α, the chassis 101 extends generally obliquely away from the mounting plane α (i.e., downwardly) in a direction from the second end wall 114 to the first end wall 113, such that the first end wall 113 is in a lower position than the second end wall 114. Thus, water received from the top opening 155 of the drip tray 100 can flow in the direction of the chassis 101 toward the first end wall 113.

In the longitudinal direction L of the chassis 101, the chassis 101 includes a bent portion 151 and a natural bent portion 152 connected to each other, the bent portion 151 being connected to the first end wall 113 at a lower position, and the natural bent portion 152 being connected to the second end wall 114 at an upper position. The bending portion 151 has a bottom bending line 103, and the bottom bending line 103 is connected to the natural bending portion 152. The bottom bend line 103 is formed by bending the chassis 101 further in a direction away from the mounting plane α (i.e., downward) so that the bottom bend line 103 can form a lowest point in each cross section of the chassis 101 in the width direction W. In other words, the bent portion 151 of the chassis 101 is inclined downward from right to left in the length direction L and also is inclined downward from the first side wall 111 and the second side wall 112 toward the bottom bending line 103 in the width direction W, respectively, to form a "V" -shaped bent portion 151 in a cross section in the width direction W. Thus, water received by the drip tray 100 can be collected at the bottom bend line 103 as it flows to the bend 151 and further flows at the distal end 157 of the bottom bend line 103 where it is connected to the first end wall 113.

In the present embodiment, the bottom bending line 103 extends along the length direction L, and when the length of the bottom bending line 103 is in the range of one third to one half of the length of the chassis 101, the shape transition between the natural bending portion 152 and the bending portion 151 thereof is smoother. And the bottom bend line 103 is located at approximately the middle of the chassis 101 in the width direction W of the chassis 101 so that the water tray 100 is symmetrical with respect to the bottom bend line 103 in the width direction W. The symmetric water receiving disc is better in universality, the front side or the back side of the sheet metal blank can be not required to be bent in the process of preparing the water receiving disc, and the product scrapping caused by wrong bending direction when the water receiving disc is asymmetric is prevented, so that the size consistency and the 100% yield of the water receiving disc are ensured. Meanwhile, the water receiving disc 100 with the symmetrical structure can meet the installation requirements of left-side drainage and right-side drainage of the unit, so that the installation and operation of the unit are more convenient.

The natural curvature 152 is connected between the curvature 151 and the edge of the chassis 101 at the second end wall 114 and has a length of two-thirds to one-half of the length of the chassis 101. The natural bending portion 152 is not formed by bending, but is formed into a complex-shaped curved surface by using the flexibility of the metal material itself of the bottom chassis 101 to naturally bend and deform so as to better guide the water received by the water tray 100 toward the bottom bending line 103. As one example, the natural curvature 152 slopes downward in a direction from the second end wall 114 to the first end wall 113 while converging toward the proximal end 158 of the bottom bend line 103, forming a curved surface that bends and deforms such that the natural curvature 152 smoothly connects between the edge of the chassis 101 at the second end wall 114 and the proximal end 158 of the bottom bend line 103. When the water received by the drip tray 100 flows to the natural bending portion 152, it is possible to gather toward the middle while flowing toward the bending portion 151, thereby guiding the received water to the bottom bending line 103 of the bending portion 151.

The water pan 100 further includes a water outlet 110, and a water outlet pipe 105 is connected to the water outlet 110, and water received from the top opening 155 of the water pan 100 can be discharged through the water outlet 110 and the water outlet pipe 105. In this embodiment, the water outlet 110 is provided in the first end wall 113 and is positioned adjacent the bottom bend line 103 of the drip tray 100 to facilitate better drainage of the water accumulation on the tray 101. By proximal here is meant that the bottom edge of the outlet opening 110 is flush with the upper surface of the chassis 101 and that the lowest point of the outlet opening 110 is arranged where the bottom bend line 103 meets the first end wall 113.

The drip tray 100 is formed of a single metal sheet through a metal integral bending process and a welding process. Specifically, the first side wall 111, the second side wall 112, the first end wall 113, and the second end wall 114 of the water deflector 156 are connected to the chassis 101 by an integral bending process. And the first side wall support wall 115, the second side wall support wall 116, the first end wall support wall 117, and the second end wall support wall 118 are connected to top edges of the first side wall 111, the second side wall 112, the first end wall 113, and the second end wall 114, respectively, by a bending process. Thus, only one sheet of metal is required to be bent to form the various side, end and bottom walls 101 of the drip tray 100.

And, the first side wall 111, the second side wall 112, the first end wall 113 and the second end wall 114 are connected by a welding process. A fillet weld 124 is formed by welding between the first side wall 111 and the first end wall 113, a fillet weld 121 is formed by welding between the first side wall 111 and the second end wall 114, a fillet weld 123 is formed by welding between the second side wall 112 and the first end wall 113, and a fillet weld 122 is formed by welding between the second side wall 112 and the second end wall 114.

To facilitate bending over the chassis 101 to form the bottom bend line 103, the first end wall 113 of the drip tray 100 is formed from a first partial end wall 131 and a second partial end wall 132 that are joined together by a welding process. The first partial end wall 131 is connected to the bent portion 151 between the bottom bend line 103 and the first end wall 113, the second partial end wall 132 is connected to the bent portion 151 between the bottom bend line 103 and the second end wall 114, and the first partial end wall 131 and the second partial end wall 132 form a butt weld 125 by welding. As an example, the first end wall support wall 117 is also composed of a first portion support wall 119 and a second portion support wall 120, and the first portion support wall 119 and the second portion support wall 120 are formed by bending outwardly from top edges of the first portion end wall 131 and the second portion end wall 132, respectively. It will be appreciated by those skilled in the art that the various support walls of the drip tray 100 need not be connected to one another, but need only be connected to the bottom of the unit.

Fig. 2 is an expanded view of the water-receiving tray 100 for explaining the preparation process of the water-receiving tray 100. As shown in fig. 2, the chassis 101 is generally rectangular in shape having a pair of long side edges 261,262 and a pair of short side edges 263,264. The first side wall 111 and the first side wall support wall 115 are provided outside the long side edge 261, the second side wall 112 and the second side wall support wall 116 are provided outside the long side edge 262, the first end wall 113 and the first end wall support wall 117 are provided outside the short side edge 263, and the second end wall 114 and the second end wall support wall 118 are provided outside the short side edge 264.

The first and second partial end walls 131, 132 of the first end wall 113 are spaced apart and angled so that the first and second partial end walls 131, 132 are precisely aligned when the chassis 101 is bent downwardly along the bottom bend line 103. The angle of the bottom bend line 103 adds up to 180 ° to the angle between the first part end wall 131 and the second part end wall 132. As an example, chassis 101 is folded 176 ° inwardly along bottom fold line 103 on both sides of bottom fold line 103, with a 4 ° angle between first portion end wall 131 and second portion end wall 132. Half of the outlet 110 is provided on the first part end wall 131 and the other half is provided on the second part end wall 132, so that when the first part end wall 131 and the second part end wall 132 are aligned, the first part end wall 131 and the second part end wall 132 can form the complete outlet 110.

When the water pan 100 is manufactured, the metal sheet is cut into a desired shape by a numerical control punch or a laser cutting device, and then the metal sheet is bent. The chassis 101 is inclined at an angle θ from the first end wall 113 to the second end wall 114, i.e., the chassis 101 is inclined at an angle θ to the mounting plane α. In the bending process, each supporting wall is firstly bent outwards for 90 degrees to be formed. The first and second partial end walls 131, 132 of the first end wall 113 are then bent inwardly by (90- θ) °, the second end wall 114 is bent inwardly by (90+θ) °, and the first and second side walls 111, 112 are formed by bending inwardly by 92 °. Finally, the left side of the chassis 101 is formed by sinking and bending along the bottom bending line 103. The folded water pan 100 is welded together by argon arc welding, laser welding and other welding modes to form fillet welds 121, 122, 123, 124 and butt welds 125, thereby preparing the finished product of the water pan 100.

Fig. 3A to 3D illustrate another embodiment of a water-receiving tray according to the present application, for illustrating a specific structure of the water-receiving tray 300, wherein fig. 3A is a perspective structural view of the water-receiving tray 300 from a front side, fig. 3B is a perspective structural view of the water-receiving tray 300 from a rear side, fig. 3C is a side view of the water-receiving tray 300, and fig. 3D is a front view of the water-receiving tray 300. As shown in fig. 3A-3D, the water pan 300 is substantially identical in structure to the water pan 100 and includes a chassis 301 and a water deflector 356 disposed about the chassis 301, the water deflector 356 forming a top opening 355 at the top of the water pan 300. The water deflector 356 comprises a first side wall 311, a second side wall 312, a first end wall 313 and a second end wall 314, the first end wall 313 comprising a first part end wall and 331 a second part end wall 332. And the drip tray 300 further includes a first side wall support wall 315, a second side wall support wall 316, a first end wall support wall 317, and a second end wall support wall 318, each of which is connected to a top edge of a respective side wall. The chassis 301 includes a bending portion 351 and a natural bending portion 352, the bending portion 351 is further bent downward along the bottom bending line 303 to form, and the natural bending portion 352 is naturally bent to deform to form a curved surface having a complex shape to guide the water to flow toward the bottom bending line 303. The chassis 301, the water deflector 356 and the respective support walls are integrally formed by a metal bending process, and the respective side and end walls are connected by a welding process to form fillet welds 321, 322, 323 and 324 and butt welds 325.

Unlike the drip tray 100, the water outlet 310 of the drip tray 300 is not provided on the first end wall 313, but is provided on the chassis 301. In this embodiment, the water outlet 310 is disposed on the bottom bend line 303 and is proximate to the first end wall 313. Here, close means that the left side edge of the water outlet 310 is close to the first end wall 313, and the water outlet 310 is provided at the distal end of the bottom bend line 303. The water outlet 310 is connected with a water outlet pipe 305. Through the water outlet 310, water received through the top opening 355 can be discharged through the water outlet pipe 305.

Fig. 4 shows an expanded view of the water-receiving tray 300 for explaining a preparation process of the water-receiving tray 300. As shown in fig. 4, the developed view of the drip tray 300 is similar to the drip tray 100, except that the water outlet 310 may be formed directly on the chassis 301 by stamping.

In the existing unit, when the length of the unit is larger, the length of the top opening of the water receiving disc is correspondingly increased. The height reserved for installing the water pan at the bottom of the unit is limited, so that the inclination angle of the chassis of the water pan along the length direction is limited. The effect of draining the accumulated water in the water pan only by the inclination of the chassis is not ideal. And the surface of the water receiving disc with residual ponding can easily generate a large amount of bacteria after long-time use, thereby influencing the air quality output by the unit. In some water-receiving pans, the process of preparing and processing is complicated by providing complex shapes to drain the water from the pan.

In the drip tray of the various embodiments of the present application, in addition to guiding the flow of condensate water dripping from the unit from a higher position to a lower position of the bottom tray by providing a horizontal support wall and the bottom tray inclined downward in the length direction, a bottom bending line that is further bent downward is provided at the lower position of the bottom tray, so that the water flowing toward the lower position can be further collected toward the bottom bending line and discharged. And the bottom bending line does not occupy the whole length direction, but utilizes the flexible natural bending of the metal sheet at the part without bending, so that the chassis can smoothly transition from a higher natural bending part to a lower bending part, thereby effectively guiding the accumulated water on the chassis. Therefore, water can not be accumulated in the water receiving disc basically, the service life of the water receiving disc is prolonged, and bacteria can be reduced. A certain amount of copper is also added into the metal sheet, so that the water pan can effectively inhibit or kill escherichia coli and staphylococcus aureus.

In addition, in the preparation process of the water pan, each side wall, each end wall and each supporting wall are formed and connected with the chassis through an integral bending process by one metal sheet, and each side wall and each end wall are connected through a welding process, so that the number of parts is reduced, the number and the length of welding seams can be reduced, and the preparation and processing efficiency of the water pan are improved.

While the present disclosure has been described in conjunction with the examples of embodiments outlined above, various alternatives, modifications, variations, improvements, and/or substantial equivalents, whether known or that are or may be presently or later be envisioned, may be apparent to those of ordinary skill in the art. Accordingly, the examples of embodiments of the disclosure as set forth above are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit or scope of the disclosure. Accordingly, the present disclosure is intended to embrace all known or earlier developed alternatives, modifications, variations, improvements and/or substantial equivalents.
