Description

TECHNICAL FIELD

[0001] The present application relates to the field of elevator technology, in particular to an elevator air conditioner. BACKGROUND

[0002] The elevator air conditioner is different from the household air conditioner, and generally does not allow the condensate water generated by refrigeration to be directly discharged into the elevator shaft, and needs to consume the condensate water through the technical capability of the air conditioner itself. Therefore, the elevator air conditioner is usually equipped with a water accumulation tray, and the water pump is used to suck and spray the accumulated water to the condenser to realize evaporation consumption, for example, Chinese patent document 1 (CN 213395856U) and Chinese patent document 2 (CN 216667959U).

[0003] During the working process of the elevator air conditioner, a large amount of heat exchange is needed on the condenser side and the evaporator side. Therefore, dust and other floating objects in the air will be brought into the air conditioner during the heat exchange process. Although the elevator air conditioner is equipped with a filter screen, a large amount of dust will still pass through the gap between the filter screens in order to reduce the air resistance, and finally be intercepted on the condenser and the evaporator. During the water treatment process, the accumulated water is sprayed onto the condenser, bringing the dust into the water accumulation tray.

[0004] The process of generating condensate water and treating condensate water by the elevator air conditioner is not completely synchronized. The condensate water is generated after the compressor is started, and the water treatment function of the elevator air conditioner is triggered when the condensate water accumulates to a certain amount. Moreover, when the condensate water generation speed of the elevator air conditioner exceeds the accumulated water treatment capacity in the extreme working condition, a large amount of accumulated water will be generated in the bottom plate of the elevator air conditioner. With the passage of time, the dust in the water accumulation tray gradually deposits or becomes more turbid, and needs to be cleaned regularly.

[0005] The documents 1 and 2 have the following problems: 1. The structure of the water accumulation tray is complex and difficult to clean; 2. During the flushing process of the water accumulation tray, dirt is easy to block the water pump and the high-pressure spray head; 3. The high-pressure spray head can only clean the local area, and it is difficult to clean the entire water accumulation tray. SUMMARY

[0006] The technical problem to be solved by the present application is how to conveniently clean the water accumulation tray of the elevator air conditioner.

[0007] To solve the above technical problems, the present application provides an elevator air conditioner, comprising an air conditioner body and a water accumulation tray assembly, characterized in that the air conditioner body comprises at least one pair of fixing seats and at least one pair of lifting lugs; the elevator air conditioner is fixed on the elevator car roof support through the fixing seats; the water accumulation tray assembly comprises at least one pair of locks and at least one pair of drain ports; the positions of the locks match the lifting lugs, so that the water accumulation tray assembly is fixed on the lower part of the air conditioner body through the cooperation of the locks and the lifting lugs.

[0008] Preferably, the fixing seat is arranged on both sides of the air conditioner body, and the lug is arranged on the front side and the rear side of the air conditioner body.

[0009] Preferably, the water pan assembly does not overlap with the roof support in a vertical projection plane.

[0011] Preferably, the air conditioner body further comprises a guide frame, and the guide frame has a peripheral size smaller than an inner size of the water pan assembly.

[0012] Preferably, the water pan assembly further comprises an elastic sealing member, and the guide frame and the elastic sealing member have corresponding wedge surfaces.

[0013] Preferably, the connecting rod is made of an elastic material, the lock catch is in a stretched state when in a locked state, the elastic sealing member is in a compressed state, and an included angle a between a connecting line of the third rotation shaft and the second rotation shaft and a vertical direction is greater than 0°.

[0014] The application further provides an elevator air conditioner, comprising an air conditioner body and a water pan assembly, wherein the air conditioner body comprises at least one pair of fixing seats and a track; the elevator air conditioner is fixed on an elevator roof support through the fixing seats; the track is fixed on both side edges of a lower part of the air conditioner body; the water pan assembly comprises at least one cavity, a handle and a drainage opening; and the water pan assembly is horizontally movably arranged on the track of the lower part of the air conditioner body.

[0016] Preferably, the air conditioner body comprises a baffle, the baffle is rotatably connected to the air conditioner body through a shaft; after the baffle is rotated to a preset position one, a vertical projection of the baffle does not overlap with the cavity; and after the baffle is rotated to a preset position two, the vertical projection of the baffle overlaps with the cavity.

[0017] Compared with the prior art, the elevator air conditioner has the following technical effects:

[0032] The water collection tray assembly 200 does not overlap with the car roof supports 205 and 206 in the vertical projection plane.

[0033] The lock 201 includes a connecting rod 210 and a paddle 213. The connecting rod 201 has a first rotating shaft 211 and a second rotating shaft 212, and the paddle has a third rotating shaft 214. The paddle 213 and the connecting rod 201 share the second rotating shaft 212, while the paddle 213 and the water tray assembly 200 share the third rotating shaft 214.

[0034] The air conditioner body 100 further includes a guide frame 105 , and the outer dimension of the guide frame 105 is smaller than the inner dimension of the water collection tray assembly 200 .

[0036] The connecting rod 210 is made of elastic material. When the lock buckle 201 is in the locked state, the connecting rod 210 is in a stretched state and the elastic seal 207 is in a compressed state. The tension of the connecting rod 210 is balanced with the pressure between the guide frame 105 and the elastic seal 207. The angle a between the line connecting the third rotating shaft 214 and the second rotating shaft 212 and the vertical direction is greater than 0°, thereby realizing the locking of the lock buckle 201 in the counterclockwise rotation direction along the third rotating shaft 214.

[0037] Cleaning method 1 of the water tray assembly 200:

[0038] like Figure 5 As shown, the relative positions of the air conditioner body 100 and the car top device 300 are such that the car top device 300 is on the left side of the air conditioner body 100 .

[0040] Step 2: Turn the latch 201 on one side of the elevator air conditioner, and turn the tab 213 along the third axis 214. Accordingly, the second axis 212 rotates around the third axis 214, and then the first axis 211 is disengaged from the tiger mouth of the lug 101.

[0041] Step 3: After the first axis 211 of the latch 201 is disengaged from the tiger mouth of the lug 101, the entire latch 201 will continue to rotate around the lug 102 as the fulcrum. Remove the closure of the drain 204 and continue to drain the accumulated water in the sump.

[0043] Step 5: After cleaning, reverse the steps 1-4 to restore.

[0044] Sump assembly 200 cleaning method two:

[0045] As shown in Figure 6 , the relative position of the air conditioner body 100 and the car top device 300 is that the car top device 300 is on the right side of the air conditioner body 100. Compared with cleaning method one, first loosen the latch 202, and the other steps are the same as cleaning method one.
