It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0031] The heat exchanger of the air conditioner generally produces condensate water when working, and the condensate water flows along the surface of the heat exchange pipe on the heat exchanger to the bottom end of the heat exchanger, so the heat exchanger is generally provided with a water pan structure, which is used to catch the condensate water on the heat exchanger. The fixing method of the heat exchanger and its water pan structure in the existing air conditioner is screw fixing, glue fixing, etc., but when there are other installation requirements for the unit, additional auxiliary parts are needed to fix the heat exchanger and the water pan structure. Because the heat exchanger itself has a certain weight, it is more cumbersome and laborious to install and disassemble the heat exchanger.

[0032] As shown in Figures 1-2 The present application provides a composite water pan and an air conditioner. The composite water pan comprises: a main water pan 17, an auxiliary water pan 15 and a spliced water pan.

[0040] As Figures 1-2 shown, the composite water pan includes: main water pan 17, auxiliary water pan 15 and splicing water pan, the auxiliary water pan 15 and the main water pan 17 with the main water pan 17 are assembled into the splicing water pan from top to bottom at the same time by using its own gravity, the main water pan 17 is fixed by using a plurality of splicing water pan hooks 7 on the splicing water pan, forming a composite water pan.

[0041] The bottom plate 5 of the splicing water pan has a rectangular opening in the middle, the four sides of the inside of the opening are divided into a plurality of clamping plates 8, the clamping plates 8 are perpendicular to the bottom plate 5, the clamping plates 8 are not connected to each other, the two sides of the bottom plate 5 are vertically provided with limiting plates 6, part of the limiting plates 6 are provided with splicing water pan hooks 7 inward, and the two ends of one side of the limiting plate 6 are provided with water flow holes 16. The two ends of the splicing water pan are provided with sliding rails, specifically, the two ends of the bottom plate 5 are vertically provided with connecting plates 43, and the top of the connecting plates 43 is connected with outwardly bent supporting tongues 9.

[0042] The main water pan 17 is a rectangular recess with a rectangular opening in the middle, the main water pan 17 can be fitted with the splicing water pan, one side of the main water pan 17 is provided with a water flow hole 16, and the condensed water is gathered in the recess to flow out of the water flow hole 16.

[0043] The auxiliary water pan 15 is a rectangular panel with grooves around as water flow grooves, one side of the water flow grooves is provided with a water flow hole 16 for condensed water to flow out, one end of the main water pan 17 can be vertically sleeved in one end of the auxiliary water pan 15, and one end of the auxiliary water pan 15 is also provided with a foot pad to make the auxiliary water pan 15 have a slope to make the condensed water flow out of the water flow hole 16 at one end, and the foot pad is on the side opposite to the water flow hole 16.

[0044] As Figures 3-5 shown, the bracket includes two open C-shaped brackets and a base support strip, the two C-shaped brackets are fixed below the side plates of the shell 18 respectively, the positions of the two C-shaped brackets correspond horizontally, and the base support strip is fixed with the C-shaped brackets.

[0045] As Figure 3 shown, the C-shaped bracket includes a supporting plate 3, a side plate 42 and a fixing plate 2, and the C-shaped bracket is also used as a sliding groove (i.e. the C-shaped bracket is a sliding groove), the supporting plate 3 is a rectangular plate with downwardly recessed rectangular receiving grooves 4 at both ends for fixing with the base support strip, one side of the supporting plate 3 is vertically connected with one side of the side plate 42, the side plate 42 is a rectangular panel with an oval recess 1, the recess 1 is used to limit the position of the splicing water pan and reduce friction with the splicing water pan, the other side of the side plate 42 is vertically connected with a rectangular fixing plate 2, and the cross section of the vertically connected supporting plate 3, side plate 42 and fixing plate 2 is "C" shaped, so it is called C-shaped bracket here.

[0046] AsFigure 4 As shown, the base support bar includes a support column 11 and a base support plate overlap 10. The support column 11 is a rectangular column, and one side of the support column 11 is connected to the rectangular base support plate overlap 10. The width of the base support plate overlap 10 corresponds to the width of the C-shaped bracket storage groove 4.

[0047] like Figure 7 As shown, the mounting plate 12 has screw holes on its rectangular panel and an inwardly bent mounting plate hook 13 on one side for fixing the composite water receiving tray to a horizontal position.

[0048] like Figures 8-9 As shown, in a specific example, the composite water receiving tray is installed inside the air conditioner. When the unit is installed vertically, the C-shaped bracket is fixed on the side plates on both sides of the housing 18. The overlapping edge of the base support strip is attached to the storage groove 4 of the C-shaped bracket and then fixed. At this time, the support column 11 is below the C-shaped bracket. The C-shaped bracket and the base support strip form a bracket inside the housing 18. The bracket is used to fix the composite water receiving tray. The composite water receiving tray includes a spliced ​​water receiving tray, a main water receiving tray 17 and an auxiliary water receiving tray 15. The auxiliary water receiving tray 15 with a water flow hole 16 is vertically sleeved on one end of the main water receiving tray 17. The main water receiving tray 17 is equipped with a heat exchanger 19. The heat exchanger 19 is a "V"-shaped heat exchanger 19 composed of two flat plate heat exchangers 19 with rectangular cross sections, one end of which is far away from each other and the other end is connected to each other. The far end of the "V"-shaped heat exchanger 19 is installed on the main water receiving tray 17. The auxiliary water receiving tray 15 and the main water receiving tray 17 with heat exchanger 19 are simultaneously assembled into the spliced ​​water receiving tray from top to bottom using their own weight. The main water receiving tray 17 and the spliced ​​water receiving tray are fixed in the spliced ​​water receiving tray by the connecting plate 43, the clamping plate 8, the limiting plate 6, the bottom plate 5 and the spliced ​​water receiving tray hook 7. The two water flow holes 16 of the main water receiving tray 17 are corresponding to the two water flow hole 16 locking positions of the spliced ​​water receiving tray, and the water flow holes 16 are locked in the corresponding water flow hole 16 locking positions.

[0049] Using the slide rail of the composite water receiving tray in conjunction with the bracket, the composite water receiving tray is installed into the bracket. The spliced ​​water receiving tray of the composite water receiving tray can be completely wrapped in the C-shaped bracket (slide groove), and its vertical freedom is completely restricted. After the composite water receiving tray is pushed inward into place, the mounting plate 12 is fixed on the base support plate 3. The mounting plate hook 13 on the mounting plate 12 is locked on the limiting plate 6 of the spliced ​​water receiving tray to fix the composite water receiving tray. Disassembly and assembly are the reverse of the above steps, which is quick and convenient.

[0050] Since the C-shaped bracket completely encloses the composite water tray, when the unit is horizontally installed, that is, when the vertically installed air conditioner is rotated 90 degrees to the left or right, the fixing plate 2 of the C-shaped bracket fits tightly with the support tongue 9 on the splicing water tray. At the same time, the splicing water tray hook 7 assists in limiting the position and prevents the water tray component from tipping over due to gravity. No other auxiliary parts are needed, saving costs.

[0051] Disassembly is contrary to the above steps, first remove the mounting plate 12, pull out the composite water pan from the bracket, after pulling out the composite water pan, disassemble the heat exchanger 19, main water pan 17 and auxiliary water pan 15, the disassembly method is simple and convenient.

[0052] Preferably, one end of the auxiliary water pan 15 is sleeved with one end of the main water pan 17, which can be selected according to actual needs.

[0053] Preferably, a sponge can be added between the spliced water pan and the main water pan 17 to prevent condensation. The sponge is a common sponge. In this state, the sponge is not exposed, so the sponge in this state can achieve the fireproof function even if it is a common sponge.

[0054] Preferably, the material of the spliced water pan can be sheet metal.

[0055] Preferably, the spliced water pan can be an injection molding part.

[0056] The present application sets the main water pan 17, the auxiliary water pan 15 and the spliced water pan to form a composite water pan, and then fixes the heat exchanger 19 on the composite water pan, and then installs it in the shell 18 through the bracket, solves the problem that it is complicated and laborious to install and disassemble the heat exchanger 19, and increases the sponge between the spliced water pan and the main water pan 17 to prevent condensation. The sponge is a common sponge. In this state, the sponge is not exposed, so the sponge in this state can achieve the fireproof function even if it is a common sponge.
