Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

Example 1

The structure of seat loop wheel machine among the prior art is generally as shown in fig. 1 ~ 3, current seat loop wheel machine indoor unit generally includes the shell body, air intake and air outlet formed on the shell body, set up evaporimeter and fan in the shell body, wherein, the evaporimeter sets up in the shell body aslope, the air outlet sets up the one side at the evaporimeter, the air intake sets up the one side at the fan, and air outlet and air intake are located the same one side of shell body, downside at the evaporimeter is equipped with the water collector, the water collector is used for collecting the comdenstion water that the evaporimeter produced, and in time discharge it. When the base crane chamber is installed indoors by a base type installation method, the whole base crane is arranged along the vertical direction, the air outlet is positioned at the upper part of the base crane, the evaporator is positioned above the fan, and the evaporator is obliquely arranged above the water receiving disc; when the base crane room is installed indoors by a ceiling type installation method, the base crane is installed in the horizontal direction as a whole, the air outlet and the evaporator are located at the front end of the base crane, the fan is located at the rear end of the base crane, and the evaporator is obliquely arranged above the water receiving disc.

In the operation process of the base crane, outside air firstly enters the base crane from the air inlet under the action of the fan, then passes through the evaporator from the air inlet surface of the evaporator, is discharged from the air outlet surface of the evaporator, and finally is blown out from the air outlet. When the surface temperature of the evaporator of the pedestal crane is lower than the dew point temperature of the air inlet flow, water vapor is condensed on the surface of the evaporator to generate condensed water, and at the moment, the condensed water on the surface of the evaporator needs to be completely and timely led out to prevent the condensed water from randomly spreading, corroding or rusting the internal parts of the air conditioner.

Specifically, second evaporator side board 141 is including the first side board body, second side board body and the third side board body that connect gradually, the laminating of second side board body the terminal surface setting of return bend end 14, first side board body is located the second side board body is close to one side of air-out face 12, first side board body certainly the second side board body is to keeping away from the direction of evaporator 1 extends, third side board body is located the second side board body is close to one side of air inlet face 11, third side board body certainly the second side board body is to keeping away from the direction of evaporator 1 extends, the U-shaped heat exchange tube that exposes on the return bend end 14 passes behind the second side board body, hold in the second evaporator side board 141.

Furthermore, the second water deflector 4 is located on the same side of the air inlet surface 11, the second water deflector 4 includes a connection plate 41 and a protection plate 42, and the connection plate 41 and the protection plate 42 are vertically connected and respectively extend from the upper side 15 to the lower side 16 along the bent end 14 of the evaporator 1. The connecting plate 41 is arranged parallel to the third side plate body, the connecting plate 41 is partially overlapped and connected with the third side plate body, the protection plate 42 is positioned on one side of the connecting plate 41 far away from the evaporator 1, and the protection plate 42 extends from the connecting plate 41 to one side close to the first side plate body and is vertically connected with the connecting plate 41.

Thus, the return bend end 14 of the evaporator 1 forms the drainage groove 142 through the second water guide plate 4 and the second evaporator side plate 141, wherein the first side plate body forms one side groove wall of the drainage groove 142, the second side plate body forms the groove bottom surface of the drainage groove 142, the third side plate body and the second water guide plate 4 together form the other side groove wall of the drainage groove 142, and one end of the drainage groove 142 is inserted into the water receiving tray 2, so that no matter the seat crane adopts seat type installation or ceiling type installation, condensed water generated by the heat exchange tube at the return bend end 14 of the evaporator 1 can flow into the water receiving tray 2 under the guidance of the drainage groove 142.

Moreover, the arrangement of the protection plate 42 can also improve the water storage capacity of the drainage groove 142, so that when the amount of condensed water in the drainage groove 142 is large, the condensed water can still smoothly flow into the water pan 2 along the drainage groove 142.

Further, the first side plate body is fixedly connected with the outer shell 8, and the bent end 14 of the evaporator 1 is fixed, so that the evaporator is prevented from being deviated in the use or carrying process.

Furthermore, a water guide groove 21 is arranged in the water pan 2, a plurality of drain holes 22 are arranged on the water guide groove 21, and the condensed water flowing into the water pan 2 can flow into the drain holes 22 under the guidance of the water guide groove 21 and is discharged out of the seat crane through the drain holes 22.

Further, as shown in fig. 4 to 7, a top foam 5 is disposed at a joint of the evaporator 1 and the outer shell 8, the top foam 5 is clamped between the upper side surface 15 of the evaporator 1 and the outer shell 8, and by the arrangement of the top foam 5, the temperature of the evaporator 1 can be prevented from being transmitted to the outer shell 8, and condensation is generated on the surface of the outer shell 8.

Furthermore, the end portions of the first water guide plate 3 and the cover plate 7 abut against the top foam 5, so that the sealing performance of the first water guide plate 3 and the cover plate 7 on the connecting end 13 of the evaporator 1 can be further improved, and components such as capillary tubes and the like on the connecting end 13 are better in sealing performance and are not leaked.

In addition, this application still provides an air conditioner, the air conditioner has foretell comdenstion water drainage device.

In summary, it is easy to find that: this application comdenstion water drainage device and air conditioner have following advantage: firstly, different installation modes of a seat crane can be suitable, no matter the seat crane is installed in a seat or a ceiling type, no change is needed, the condensate water drainage device and the air conditioner can drain condensate water, so that the condensate water can completely flow into the water receiving tray 2; secondly, the condensate water drainage device and the air conditioner are simple in structure, the drainage channel is smooth and straight, rapid drainage of condensate water is facilitated, and the first water guide plate 3, the second water guide plate 4 and the cover plate 7 are rapidly assembled; thirdly, the condensed water drainage device and the air conditioner can completely collect and guide the condensed water of each part of the evaporator 1, so that the condensed water can be completely collected into the water receiving tray 2; fourthly, the condensate water drainage device and the air conditioner can be realized by simple modification on the basis of the existing evaporator, and have small space occupation and wide application range; fifth, this application condensate water drainage device can cover and seal, right to the link 13 of evaporimeter 1 the return bend end 14 is fixed for evaporimeter 1's protecting effect is better, and is not fragile.
