Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a water tray filter structure for carrying evaporator condensate in a refrigeration system and a ceiling machine having the water tray filter structure. Background Technology

[0002] Cavity-mounted air conditioners are a commonly used type of air conditioning system. For example... Figure 1 As shown, the air outlet section of the joist air conditioner includes a panel 01, an air guide plate 02, a drip tray 3, a drip tray duct opening 36, a water pump 04, and an evaporator 05. When the joist air conditioner is running, the condensate produced by the evaporator 05 flows into the drip tray 3 below and is then discharged by the water pump 04. However, the condensate flow from the evaporator 05 can easily wash debris from the drip tray to the water pump inlet. Over time, the accumulation of impurities at the inlet can generate bacteria and clumps, easily clogging the water pump inlet. Once the water pump inlet is blocked, the water in the drip tray cannot drain, causing leakage when the unit starts. Leaks caused by water pump blockage usually require removing the unit panel or directly disassembling the drip tray and other components to clean the drip tray and water pump. This operation is complex and inconvenient for workers or users to clean the drip tray and water pump for maintenance.

[0003] To solve the problem that the water pump of the water receiving tray is easy to be blocked, a water drainage mode of a ceiling air conditioner unit is provided, wherein the impeller and the end cover of the water pump arranged above the water receiving tray are made of a material that can shrink and expand with heat. When the impeller and the end cover of the water pump are subjected to cold, they will extend to the bottom of the water receiving tray; when the impeller and the end cover of the water pump are subjected to heat, they will shrink and return to the initial state. By detecting the operation state of the air conditioner unit and controlling the rotating direction of the water pump when the air conditioner unit is operating in the refrigeration mode, the condensed water in the water receiving tray can be drained, and the water pump can be self-cleaned, so that the dirt remaining in the water pump and the sticky mass accumulated at the water inlet of the water pump can be discharged, and the water pump can be prevented from being blocked by the suction of impurities and the sticky mass, thereby solving the problem of low drainage efficiency caused by the blockage of the water pump due to dirt, and ensuring the normal operation of the air conditioner unit. The way of cleaning the dirt is passive, that is, the dirt is removed only after being sucked into the water pump and causing blockage. Once hard objects such as small stones left over from decoration are sucked in and cause tight blockage, it is difficult to remove them by using the power of the water pump itself. Another water drainage device of a ceiling air conditioner unit includes a bottom tray, a water pump and a drainage nozzle arranged in the corner of the bottom tray, a side plate arranged outside the bottom tray, wherein the drainage nozzle is connected to the water pump through a curved drainage pipe, and the drainage nozzle is inclined to extend out of the side plate. By inclining the drainage nozzle to extend out of the side plate and connecting the water pump through the curved drainage pipe, the inclined drainage nozzle structure effectively utilizes the corner space of the ceiling air conditioner unit, does not occupy the installation space of the water pump, and is convenient to disassemble and assemble. However, once the water inlet of the water pump is blocked, the relevant panel needs to be disassembled, and maintenance and repair are also troublesome.

[0004] Therefore, how to overcome the defects that the water receiving tray and the water pump of the existing ceiling air conditioner unit are easy to be blocked and difficult to be maintained and operated is a problem that needs to be solved as soon as possible in the field. SUMMARY

Then, the filter screen and the water receiving tray are connected and fixed accurately and conveniently by the pressing buckle on the other side. When the filter screen needs to be disassembled or installed, the air deflector of the corresponding air port is only needed to be disassembled, and the purpose can be achieved by operating in the blind air duct of the water receiving tray, so that the working efficiency is greatly improved.

[0008] Preferably, the side of the filter screen with magnetic attraction structure is further provided with a filter screen positioning buckle, and the corresponding side of the water receiving tray is provided with a magnetic attraction side positioning hole connected with the filter screen positioning buckle.

[0009] When the side of the filter screen with magnetic attraction structure is connected with the water receiving tray, the filter screen positioning buckle on the same side is connected with the magnetic attraction side positioning hole on the corresponding side of the water receiving tray, so that the filter screen and the water receiving tray are firmly connected to avoid misalignment of the filter screen due to vibration and affect the filtering effect.

[0010] Preferably, the bottom of the filter screen is provided with a hook-shaped structure. The hook-shaped structure can smoothly intercept flocculation, hair and other impurities in the water flow of the water receiving tray.

[0016] Preferably, the magnetic attraction structure is at least two pairs, which are arranged along the longitudinal direction of the side of the filter screen.

[0017] The two pairs of magnetic attraction structures are arranged at the upper and lower ends of the side of the filter screen, which can ensure the stability of the connection between the filter screen and the water pan.

[0018] Preferably, the magnetic attraction structure is preferably three pairs.

[0019] The three pairs of magnetic attraction structures are arranged along the longitudinal direction of the side of the filter screen, which can ensure the reliability and stability of the connection between the filter screen and the water pan.

The magnetic attraction structure is a convex magnetic structure and a concave magnetic structure. In the blind area, the convex and concave structures of the magnetic attraction structure on one side can be used to realize self-adjustment and centering positioning, and the filter screen and the water pan are connected by attraction. Then, the filter screen and the water pan can be accurately and conveniently connected and fixed by the press buckle on the other side, so that the precise connection operation of the filter screen and the water pan in the blind area is realized. When the filter screen positioning buckle on one side of the filter screen is connected with the magnetic attraction side positioning hole of the water pan, the filter screen and the water pan are firmly connected, and the vibration of the filter screen in the future can be avoided to affect the filtering effect. When disassembling, the press buckle connection is released by pressing the press switch on the outside, and then the magnetic attraction structure on the inside is pulled apart, so that the disassembly of the filter screen is completed. The filter screen is installed at the water outlet of the water pan, and the bottom of the filter screen is provided with a hook-shaped structure. When the water pan is draining, the hook-shaped structure can smoothly intercept the flocculent matter, hair and other impurities in the water flow.
