According to another embodiment of the present invention, there is provided an indoor unit of an air conditioner, including a housing 30 and an evaporator located in the housing 30, the evaporator being the evaporator of the above embodiment. The air conditioning indoor unit applying the evaporator of the embodiment comprises an evaporator body 40, and an air pipe 10 and a liquid pipe 20 which are arranged on the evaporator body 40, wherein a first joint 11 is arranged at the end part of the air pipe 10, a second joint 21 is arranged at the end part of the liquid pipe 20, and the first joint 11 and the second joint 21 are arranged at intervals so that an avoidance gap is formed between the first joint 11 and the second joint 21. Therefore, in the helium inspection and after-sales installation processes of the evaporator, the air pipe and the liquid pipe can be staggered, and the helium inspection and after-sales installation are convenient. The problems that in the prior art, the air pipe and the liquid pipe of the evaporator connecting pipe with the two outlet pipes are arranged in parallel and are difficult to operate in the helium inspection and after-sales installation process are solved.
In order to facilitate the connection between the air pipe 10 and the liquid pipe 20 on the evaporator body 40 and the pipelines of the outdoor unit, the shell 30 is provided with a blanking hole 31 for avoiding the pipe body, and when the air pipe 10 or the liquid pipe 20 is assembled in the shell 30 in a bending mode, the blanking hole 31 can facilitate the pipeline of the outdoor unit to penetrate through the shell 30 and be connected with the air pipe 10 or the liquid pipe 20. When the air pipe 10 and/or the liquid pipe 20 are connected with the respective connectors by adopting flexible pipe bodies, the blanking hole 31 can facilitate the first connector 11 on the air pipe 10 or the second connector 21 on the liquid pipe 20 to be drawn out from the blanking hole 31 so as to be connected with a pipeline of the outdoor unit.
In order to adapt to different indoor installation orientations of the air conditioner indoor unit, the air conditioner indoor unit is convenient to install. As shown in fig. 8, the air pipe 10 and the liquid pipe 20 are arranged in pairs, two ends of the evaporator body 40 are provided with a pair of the air pipe 10 and the liquid pipe 20, and correspondingly, a pair of blanking holes 31 are correspondingly formed in the shell 30, alternatively, as shown in fig. 8 and 9, two blanking holes 31 are respectively formed in end plates 32 at two ends of the shell 30, and each pair of the air pipe 10 and the liquid pipe 20 is connected with a pipeline of an outdoor unit through one blanking hole 31 in the end plate 32 at one end of the shell 30.
In addition, in order to adapt to the angle between the bent air pipe 10 and the liquid pipe 20, as shown in fig. 10 and 11, two pairs of blanking holes 31 are formed in the housing 30, each pair of blanking holes 31 is formed in one end of the housing 30, and because the angle between the air pipe 10 and the liquid pipe 20 is 90 °, one blanking hole 31 in each pair of blanking holes 31 is formed in the end plate 32 at one end of the housing 30, the other blanking hole 31 is formed in the side plate 33 at one end of the housing 30, and the forming directions of the two blanking holes 31 form an included angle of 90 °; one of the air pipe 10 and the liquid pipe 20 is connected with a pipeline of the outdoor unit through a blanking hole 31 on the end plate 32, and the other is connected with the pipeline of the outdoor unit through a blanking hole 31 on the side plate 33.
Each pair of blanking holes 31 at one end of the casing 30 is located at a corner of the casing 30, and for the overall aesthetic appearance of the casing 30, optionally, as shown in fig. 12, a casing portion between each pair of blanking holes 31 may be removed, that is, two blanking holes 31 of each pair of blanking holes 31 are mutually communicated, so that the casing 30 is more aesthetic while satisfying the pipe connection between the air pipe 10 and the liquid pipe 20 and the outdoor unit.
The evaporator of the embodiment of the invention adopts a connecting pipe distribution mode as shown in fig. 3 and 4, and one of the connecting pipes in the air pipe 10 and the liquid pipe 20 adopts a bending design for distribution, so that the direct connection of the pipe in the installation process of after-sales personnel is facilitated. In this case, as shown in fig. 8, a connection pipe between the pipe and the outdoor unit pipe can be realized by using one blanking hole 31.
Alternatively, the air pipe 10 or the liquid pipe 20 may not be bent, but still be in an existing visual connection structure, and at this time, after-sales personnel need to perform pipe breaking operation on the air pipe 10 or the liquid pipe 20 vertically downward in the process of assembling the pipe connection air conditioner, bend the air pipe 10 or the liquid pipe 20 to a direction facing the end plate 32 of the air conditioner housing 30, and then perform pipe connection assembling work.
Under this scheme, there is no effect on the appearance of the housing 30 of the air conditioner, and the problems of production helium inspection and after-sales installation of the evaporator can be satisfied by only fine adjustment of the pipeline.
In order to facilitate connection, namely, on the basis of an alternative scheme, a blanking hole 31 is respectively added below two ends of the appearance panel body of the shell 30 of the air conditioner, namely, one end of the shell 30 adopts two blanking holes 31 in different directions to realize connection of pipelines, and the specific structural form of the blanking holes at the moment is shown in fig. 10 and 11.
As a preferred solution, and satisfy the aesthetic requirement of appearance, two blanking holes 31 located at one end of the air conditioner housing 30 in fig. 10 and 11 can be connected into a large blanking hole in a right angle structure, i.e. two blanking holes 31 are communicated to form a large blanking hole, so as to satisfy the pipe outlet requirements of the air pipe 10 and the liquid pipe 20 in different directions, and simplify the assembly.
As an alternative to bending the air pipe 10 and the liquid pipe 20, a structural form as shown in fig. 5 and 6 is adopted, one or both of the pipelines of the air pipe 10 and the liquid pipe 20 are connected with respective connectors by adopting a hose, and the design can save space, and simultaneously, an operator can conveniently pull out the first connector 11 or the second connector 21 from the air conditioner directly in the assembling process of the air conditioner, so that the connection assembly of the pipelines is realized.
Specifically, the hose is made of high-pressure resistant metal or plastic injection molding material, one end of the hose is connected with a copper pipe of the evaporator (in screw connection or welding), and the other end of the hose is connected with a pipeline of the outdoor unit through the first joint 11 or the second joint.
As another alternative of bending the air pipe 10 and the liquid pipe 20, a structure as shown in fig. 7 is adopted, a throttling structure on the outside of the room, such as a capillary structure, is moved to the inside of the room, and the capillary is welded with the liquid pipe 20 of the evaporator, so that the outlet can be directly pulled out for assembly in the process of connecting with the outdoor unit due to the greater flexibility of the capillary.
