Detailed Description

Various embodiments of the present application will now be described with reference to the accompanying drawings, which form a part hereof. It should be understood that although directional terms, such as "front," "rear," "upper," "lower," "left," "right," "top," "bottom," and the like may be used herein to describe various example structural portions and elements of the application, these terms are used herein for convenience of description only and are to be determined based on the example orientations shown in the figures. Because the embodiments disclosed herein can be arranged in a variety of orientations, these directional terms are used for purposes of illustration only and are not to be construed as limiting.

Fig. 1A to 1D illustrate an embodiment of a water pan according to the present application, which is used to illustrate a specific structure of the water pan 100, where fig. 1A is a perspective view of the water pan 100 as viewed from a front side, fig. 1B is a perspective view of the water pan 100 as viewed from a rear side, fig. 1C is a side view of the water pan 100, and fig. 1D is a front view of the water pan 100. As shown in fig. 1A-1D, the drip tray 100 includes a base pan 101, and a water stop 156 surrounding the base pan 101 and attached over the edge of the base pan 101, the water stop 156 being flush at its top edge 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 adapted to receive condensate dripping from the unit and the water deflector 156 is adapted to block the condensate from flowing out of the edge of the base pan 101. In the embodiment, the chassis 101 and the water blocking device 156 are formed by integrally bending a stainless steel thin plate and then connected by a welding process. As an example, the copper content in the stainless steel thin plate is more than or equal to 1.5%, so that the water receiving tray 100 has a certain antibacterial effect, such as the effect of inhibiting or killing escherichia coli, staphylococcus aureus and the like.

Specifically, the water guard 156 includes a first sidewall 111, a second sidewall 112, a first end wall 113, and a second end wall 114. 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 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 base pan 101 in a circumferential direction of the base pan 101 and form a top opening 155 above the base pan 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 substantially vertically upward from the edge of the chassis 101. The height of the first end wall 113 in the vertical direction is greater than the height of the second end wall 114. And the heights of the first side wall 111 and the second side wall 112 gradually increase in a direction from the second end wall 114 to the first end wall 113 (i.e., in a direction from right to left in fig. 1C). That is, the chassis 101 is gradually inclined downward from right to left when the top edges of the respective side and end walls of the water guard 156 are at the same height.

The drip tray 100 further comprises 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 and bent outwardly from 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. In this embodiment, the top edges of the respective side walls, end walls, and the respective support walls all lie in the same mounting plane α which is flush with the bottom of the unit so that the drip tray 100 can be connected to the bottom of the unit through the respective support walls so that the top opening 155 can receive condensate dripping from the unit. When the top edges of the respective side and end walls are in the same mounting plane α, the chassis 101 extends substantially obliquely in a direction from the second end wall 114 to the first end wall 113 away from the mounting plane α (i.e. downwards) 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 a direction along the base pan 101 toward the first end wall 113.

In the length direction L of the bottom chassis 101, the bottom 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 a higher position. Flexure 151 has a bottom flexure line 103, with bottom flexure line 103 connected to a natural flexure 152. The bottom bending line 103 is formed by further bending the bottom plate 101 in a direction away from the mounting plane α (i.e., downward), so that the bottom bending line 103 forms the lowest point in each cross section of the bottom plate 101 in the width direction W. In other words, the bent portion 151 of the chassis 101 is downwardly inclined from right to left in the length direction L and also downwardly inclined in the width direction W from the first and

second side walls

111 and 112 toward the bottom bending line 103, 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 is able to converge toward the bottom bend line 103 as it flows to the bend portion 151 and further toward the distal end 157 where the bottom bend line 103 connects 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 bottom chassis 101, the shape transition between the natural bending portion 152 and the bending portion 151 is smoother. And the bottom bending line 103 is located at approximately the middle of the bottom chassis 101 in the width direction W of the bottom chassis 101, so that the drain pan 100 is symmetrical with respect to the bottom bending line 103 in the width direction W. The water pan with the symmetrical shape has better universality, the front or the back of a metal sheet blank does not need to be bent in the process of preparing the water pan, and the product scrapping caused by wrong bending direction when the structure of the water pan is asymmetrical is prevented, so that the size consistency and the 100 percent yield of the water pan are ensured. Meanwhile, the water pan 100 with the symmetrical structure can meet the installation requirements of left-side drainage and right-side drainage of the unit, so that the unit is more convenient to install and operate.

The natural curvature 152 is connected between the bent portion 151 and the edge of the bottom chassis 101 at the second end wall 114, and has a length of two thirds to one half of the length of the bottom chassis 101. The natural bending part 152 is not formed by bending, but naturally bends and deforms to form a curved surface with a complicated shape by the flexibility of the metal material of the bottom plate 101 itself, so as to better guide the water received by the drip tray 100 to flow toward the bottom bending line 103. As an example, the natural bending portion 152 may be curved to bend toward the proximal end 158 of the bottom bend line 103 while being inclined downward in a direction from the second end wall 114 to the first end wall 113, such that the natural bending portion 152 is smoothly connected between the edge of the bottom chassis 101 at the second end wall 114 and the proximal end 158 of the bottom bend line 103. When water received by the drip tray 100 flows to the natural bending portion 152, the water can be gathered toward the middle while flowing toward the bending portion 151, thereby guiding the received water toward the bottom bending line 103 of the bending portion 151.

The drip tray 100 further includes a water outlet 110, a water outlet pipe 105 is connected to the water outlet 110, and water received by the drip tray 100 from the top opening 155 can be discharged through the water outlet 110 and the water outlet pipe 105. In this embodiment, the water outlet 110 is disposed on the first end wall 113 and is disposed near the bottom bend line 103 of the drip tray 100 to better drain accumulated water on the bottom tray 101. Here, close means that the bottom edge of the water outlet 110 is flush with the upper surface of the bottom plate 101, and the lowest point of the water outlet 110 is located where the bottom bending line 103 meets the first end wall 113.

The drip tray 100 is formed by 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 guard 156 are connected to the bottom plate 101 through 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 the 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, through a bending process. Thus, only one sheet of metal is required to bend to form the side, end and base walls 101 of the drip tray 100.

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

To facilitate the formation of the base bend line 103 in the base pan 101, the first end wall 113 of the drip tray 100 is formed by a first partial end wall 131 and a second partial end wall 132 which are joined together by a welding process. First partial end wall 131 is connected to bend 151 between bottom bend line 103 and first end wall 113, second partial end wall 132 is connected to bend 151 between bottom bend line 103 and second end wall 114, and first partial end wall 131 and second partial end wall 132 are welded to form butt weld 125. As an example, the first end wall support wall 117 is also composed of a first part support wall 119 and a second part support wall 120, and the first part support wall 119 and the second part support wall 120 are bent outward from top edges of the first part end wall 131 and the second part 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 each other, but rather need only be connected to the bottom of the unit.

Fig. 2 is an expanded view of the drip tray 100, which is used to explain a preparation process of the drip 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 properly aligned when the bottom tray 101 is bent downwardly along the bottom bend line 103. The fold angle of bottom fold line 103 and the angle between first portion end wall 131 and second portion end wall 132 add up to 180 °. As an example, bottom disk 101 bends the sides of bottom bend line 103 inward 176 ° along bottom bend line 103, with a 4 ° angle between first portion end wall 131 and second portion end wall 132. Half of the water 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 water outlet 110 thereon.

When the water pan 100 is manufactured, a 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, the respective supporting wall is first bent outward by 90 °. The first and second

section end walls

131 and 132 of the first end wall 113 are then bent inward by (90- θ) ° and the second end wall 114 is bent inward by (90+ θ) ° and the first and

second side walls

111 and 112 are formed by bending inward by 92 °. And finally, sinking and bending the left side of the bottom plate 101 along a bottom bending line 103. The water pan 100 formed by bending is welded together by welding methods such as argon arc welding, laser welding and the like to form fillet welds 121, 122, 123 and 124 and a butt weld 125, so that a finished water pan 100 can be prepared.

Fig. 3A to 3D illustrate another embodiment of a water pan according to the present application, which is used to illustrate a specific structure of the water pan 300, where fig. 3A is a perspective view of the water pan 300 from a front side, fig. 3B is a perspective view of the water pan 300 from a rear side, fig. 3C is a side view of the water pan 300, and fig. 3D is a front view of the water pan 300. As shown in fig. 3A-3D, the water-tray 300 has substantially the same structure as the water-tray 100, and also includes a bottom plate 301 and a water stop 356 disposed around the bottom plate 301, wherein the water stop 356 forms a top opening 355 at the top of the water-tray 300. The water deflector 356 includes 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 including a first partial end wall and 331 a second partial end wall 332. And the drip tray 300 further comprises 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 support wall being connected to a top edge of a respective side wall. The bottom chassis 301 includes a bent portion 351 and a natural bent portion 352, the bent portion 351 is further bent downward along the bottom bending line 303, and the natural bent portion 352 is naturally bent and deformed to form a curved surface having a complicated shape to guide accumulated water to flow toward the bottom bending line 303. The pan 301, water deflector 356 and the respective support walls are integrally formed by a metal bending process and the respective side and end walls are joined 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 bottom plate 301. In this embodiment, the water outlet 310 is disposed on the bottom folding line 303 and is close to the first end wall 313. Here, close means that the left edge of the water outlet 310 is close to the first end wall 313, and the water outlet 310 is disposed at the distal end of the bottom folding 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 drained through the water outlet pipe 305.

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

In the existing unit, when the length of the unit is larger, the length of the top opening of the water pan is correspondingly required to be increased. The height reserved for installing the water pan at the bottom of the unit is limited, so that the inclination angle of the bottom plate of the water pan along the length direction is limited. The effect of draining the accumulated water in the water collecting tray by only inclining the chassis is not ideal. And after the water pan with accumulated water is used for a long time, a large amount of bacteria can be easily generated on the surface of the water pan, so that the quality of air output by the unit is influenced. In some water trays, water in the water trays is discharged by arranging a complicated shape, and the preparation and processing process is complicated.

In the water pan of the embodiments of the present application, in addition to guiding the condensed water dropping from the unit to flow from a higher position to a lower position of the base pan by providing the horizontal support wall and the base pan inclined downward in the length direction, a bottom bending line bent further downward is provided at the lower position of the base pan, so that the water flowing to the lower position can be collected and discharged further toward the bottom bending line. And the bottom bend line of this application does not occupy whole length direction, but utilizes the flexible natural bending of sheet metal in the part that does not buckle for the chassis can be followed higher natural bending part and smoothly transited to lower bending part, thereby water accumulation on the water conservancy diversion chassis effectively. Therefore, water can not be accumulated in the water pan basically, the service life of the water pan is prolonged, and bacteria can be reduced. A certain amount of copper is added into the metal sheet, so that the water pan can effectively inhibit or kill escherichia coli and staphylococcus aureus.

In addition, the water collector of this application is at the preparation in-process, and each lateral wall, end wall and support wall are connected with the chassis shaping through integrative bending process by a sheet metal to connect through welding process between each lateral wall and the end wall, consequently not only reduced the quantity of spare part, but also can reduce the quantity and the length of welding seam, thereby improve the preparation and the machining efficiency of water collector.
