Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a water receiving tray assembly and an air conditioner. Background Art

[0002] The air conditioner mainly cools the air through the heat exchanger to achieve regulation and control of the indoor air. When the air cabinet unit is cooling, the heat exchanger cools the air. As the temperature drops, water condenses on the surface of the heat exchanger. When the static pressure of the project is selected to be too large, if there is a docking gap between the water receiving pan and the shell arranged outside the water receiving pan, or the water receiving pan and the insulation material are not well adhered, the water receiving pan will not be able to completely receive the condensed water flowing down from the heat exchanger and other components, which will cause the condensed water to flow into the air-conditioning unit, posing a serious safety hazard.

[0003] In addition, the fan needs to be installed behind the heat exchanger. For the wall cabinet unit, when the static pressure selection of the project is unreasonable, the fan air volume will increase. When the wind speed exceeds a certain value, the volutes on both sides of the fan will suck up the water in the water tray, causing the fan to blow water or blow water.

By setting the upper insulation component 51, the stop surface 511 of the upper insulation component is connected and sealed with the side wall 12 of the water receiving pan, and the upper insulation component 51 is protruded from the side wall 12 of the water receiving pan in the direction close to the accommodating chamber 11, so as to form a structure similar to an "eaves". When condensed water falls, the condensed water falling on the upper insulation component 51 will flow downward along the surface of the upper insulation component 51, and will directly fall into the accommodating chamber 11 due to gravity, and will not flow into the connecting gap between the upper insulation component 51 and the side wall 12 of the water receiving pan, so that the water receiving pan 1 can completely receive the condensed water generated on the heat exchanger 2 and other components, avoiding the situation that part of the condensed water splashed onto the inner side of the panel will flow outside the water receiving pan 1, and solves the technical problem in the related art that the condensed water overflows easily due to the docking gap of the water receiving pan assembly, affecting the product safety.

[0029] Specifically, the upper heat-insulating member 51 is fixed to the side panel 40 by glue.

[0030] In the water tray assembly of this embodiment, see Figure 2 The water receiving tray assembly includes: a water receiving tray insulation component 52, which is arranged between the water receiving tray side wall 12 and the side plate 40, and the water receiving tray insulation component 52 is connected to the side of the water receiving tray side wall 12 away from the accommodating chamber 11, and the water receiving tray insulation component 52 includes a first upper end surface 521 located at the top, and the first upper end surface 521 is connected to the stop surface 511; a lower insulation component 53, one side of the lower insulation component 53 is connected to the side plate 40, and the other side of the lower insulation component 53 is connected to the water receiving tray insulation component 52, and the lower insulation component 53 includes a second upper end surface 531 located at the top, and the second upper end surface 531 is connected to the stop surface 511. By providing a water receiving pan insulation component 52 and a lower insulation component 53, the water receiving pan insulation component 52 is bonded to the outer wall of the water receiving pan side wall 12 with glue, and the lower insulation component 53 is bonded to the side panel 40 with glue, and the water receiving pan insulation component 52 and the lower insulation component 53 are squeezed tightly against each other. By providing the water receiving pan insulation component 52 and the lower insulation component 53, the water receiving pan can be insulated, thereby improving the working efficiency of the heat exchanger. At the same time, by squeezing the water receiving pan insulation component 52 and the lower insulation component 53 against each other, the two are fitted and sealed, thereby enhancing the structural sealing between the insulation components, preventing condensed water from entering the gap between the water receiving pan insulation component 52 and the lower insulation component 53, and further preventing overflow.

[0031] In the water tray assembly of this embodiment, see Figure 3 , the width of the stop surface 511 is D, the width of the connecting end surface 121 is d1, the width of the first upper end surface 521 is d2, and the width of the second upper end surface 531 is d3, wherein D>d1+d2+d3. Through the above arrangement, it is ensured that the upper heat-insulating component 51 is protruded from the side wall 12 of the water receiving tray in the direction close to the accommodating cavity 11, so as to form an "eaves" structure, and ensure that the condensed water on the upper heat-insulating component 51 can flow into the water receiving tray along the upper heat-insulating component 51.

[0032] In some embodiments, the second upper end surface 531 is disposed protruding from the connecting end surface 121 ; and the first upper end surface 521 is disposed protruding from the connecting end surface 121 .

[0033] In some embodiments, the second upper end face 531 is arranged to protrude from the connecting end face 121. At the same time, the first upper end face 521 is flush with the connecting end face 121, and the second upper end face 531 is also arranged to protrude from the first upper end face 521. At this time, the side wall 12 of the water receiving tray is connected to the upper insulation component 51, and the lower insulation component 53 and the upper insulation component 51 are squeezed against each other to form an interference fit to prevent condensation water from entering the gap between the lower insulation component 53 and the upper insulation component 51.

[0034] In some embodiments, the second upper end surface 531 and the first upper end surface 521 are both protruded from the connection end surface 121. At this time, the water tray side wall 12 is connected to the upper heat-insulating component 51, the lower heat-insulating component 53 and the upper heat-insulating component 51 are pressed against each other, and the water tray heat-insulating component 52 and the upper heat-insulating component 51 are pressed against each other to form an interference fit, thereby preventing condensed water from entering the gap between the lower heat-insulating component 53 and the upper heat-insulating component 51 and between the water tray heat-insulating component 52 and the upper heat-insulating component 51.

[0035] In the water tray assembly of this embodiment, see Figure 1 The side panels 40 include a plurality of side panels 40 that are connected in sequence, the water receiving tray side walls 12 include a plurality of water receiving tray side walls 12 that are arranged one-to-one with the plurality of side panels 40, the plurality of side panels 40 are all connected with an upper heat-insulating component 51 and a lower heat-insulating component 53, and the plurality of water receiving tray side walls 12 are all connected with a water receiving tray heat-insulating component 52.

[0036] In some embodiments, the water receiving tray is square, and the side panels 40 include four, and the four side panels 40 are sequentially connected end to end along the shape of the square water receiving tray. According to the layout of components such as the heat exchanger in the water receiving tray assembly, the location and arrangement of the heat preservation component can be adjusted accordingly.

[0037] Specifically, the upper heat-insulating component 51, the lower heat-insulating component 53 and the water-receiving tray heat-insulating component 52 are heat-insulating cotton.

[0038] In the water tray assembly of this embodiment, see Figure 4 The water receiving tray assembly also includes a water baffle assembly 6, which is located at the air inlet 31 of the fan 3. The water baffle assembly 6 includes a water baffle 61, and a preset angle L1 is formed between the water baffle 61 and the bottom plate 13 of the water receiving tray 1. The water baffle 61 is rotatably arranged to change the size of the preset angle L1. Specifically, the preset angle L1 is located on the side away from the fan 3 between the water baffle 61 and the bottom plate 13. By adjusting the rotation angle of the water baffle 61, the size of the preset angle L1 can be changed, thereby changing the flow rate of air entering the air inlet 31 of the fan 3, adjusting the resistance of the air intake, and avoiding the situation where the fan air inlet absorbs water due to excessive air intake suction.

[0039] In the water tray assembly of this embodiment, see Figure 4The water baffle assembly 6 includes: a fixed support 62, the fixed support 62 is fixedly arranged in the water receiving tray 1, and the water baffle 61 is rotatably arranged on the fixed support 62; a cylinder 63, the extension direction of the cylinder 63 is perpendicular to the water receiving tray 1, and the water baffle 61 is connected to the piston rod of the cylinder 63. Specifically, the fixed support 62 is welded in the water receiving tray 1, and the water baffle 61 is movably connected to the fixed support 62 through a hinge structure. By controlling the piston rod of the cylinder 63 to extend, the preset angle L1 can be increased, and by controlling the piston rod of the cylinder 63 to retract, the preset angle L1 can be reduced.

[0040] In the water tray assembly of this embodiment, see Figure 4 The water tray assembly includes: a first detection component, which is used to detect the rotation speed of the fan 3; a second detection component, which is used to detect the preset angle L1; a controller, which is connected to the first detection component and the second detection component by signal, respectively, and the controller is connected to the water baffle assembly 6 by signal, and the controller controls the piston rod of the cylinder 63 to extend or retract according to the rotation speed of the fan 3 and the preset angle L1.

[0041] Specifically, see Figure 5 The control method for adjusting the preset angle L1 through the water baffle assembly 6 includes: pre-inputting the optimal angle of the water baffle 61 corresponding to the rotation speed of the fan 3 in the controller; the first detection component detects the rotation speed of the fan 3, and the controller obtains the corresponding optimal angle L0 of the water baffle 61 according to the rotation speed of the fan 3; the second detection component detects the preset angle L1, and the controller compares the size of L0 and L1, and then controls the piston rod of the cylinder 63 to extend or retract according to the comparison result; if L0≤L1, the piston rod of the cylinder 63 extends to increase L1; if L0>L1, the piston rod of the cylinder 63 shortens to reduce L1; when the size of L1 satisfies |L1-L0|≤0.1, the controller controls the cylinder 63 to stop and the water baffle 61 stops rotating.

[0042] Specifically, the optimal water baffle angle value corresponding to the rotation speed of the fan 3 is obtained by simulation.

[0043] When the speed of the fan 3 changes, after 5 seconds, the first detection component starts to detect the speed of the fan 3. This prevents the fan 3 from sucking water at its air inlet 31 due to excessive air suction caused by excessive speed of the fan 3.

[0044] In the water tray assembly of this embodiment, see Figure 1 The fan 3 includes two air inlets 31 , and a water baffle assembly 6 is disposed at each of the two air inlets 31 .
