The connecting pipe in the prior art needs to be bent from the refrigerant inlet and the refrigerant outlet at the front side of the evaporator to extend to the rear side of the evaporator, namely, the state shown in fig. 1. This arrangement has the following drawbacks: the arrangement mode of the connecting pipe ensures that the evaporator needs to be subjected to pipe breaking process in the installation process, so that the assembly efficiency is low, and the condition of damaging liquid leakage in the bending process is easy to occur. On the other hand, in order to avoid unnecessary heat exchange between the refrigerant in the existing connecting pipe and the outside, so as to improve the overall energy efficiency ratio of the air conditioner, an insulating layer, such as an insulating cotton layer, is often wrapped and arranged outside the wall of the connecting pipe; however, the heat-insulating cotton layer has limited heat-insulating effect on one hand and can not effectively prevent the refrigerant from exchanging heat with the outside; when the heat-insulating cotton layer is used for a long time, the heat-insulating cotton layer is aged, so that the heat-insulating and cold-insulating effects are further reduced, and the energy efficiency ratio of the air conditioner is reduced.

In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Example 1
The embodiment provides an air conditioner, the indoor unit of the air conditioner mainly comprises a bottom shell a310 and an evaporator arranged on the bottom shell a310, the evaporator is an important component part of a heat exchange module in the air conditioner, the heat exchange module comprises a fin a220, the cross section of which is inverted U-shaped, integrally supported by angle frames at two ends, and sealing parts are arranged at two ends of the fin a220, so that an open cavity is formed inside the inverted U-shaped fin a 220. The pipeline in the fin a220 is connected with the outdoor unit through a connecting pipeline composed of a liquid inlet pipe a2231 and a gas collecting pipe a2232. In this embodiment, the liquid inlet pipe a2231 and the gas collecting pipe a2232 are respectively provided with a tee structure a2233 and a tee structure a2234, and the tee structures a2233 and a2234 enable two sides of the fin a220 to be provided with external machine connecting ends of the connecting pipelines.
In this embodiment, the liquid inlet pipe a2231 and the gas collecting pipe a2232 are connected to a side of the fin a220 away from the motor support, and one of the three-way structures a2233 and a2234 is arranged at a position adjacent to the back plate of the base component a101, and after extending the length of the fin a220, the liquid inlet pipe a2231 and the gas collecting pipe a2 are bent into a U-shaped bend which bypasses the motor support from the side of the motor support away from the back plate of the base component a101, reaches the lower edge of the back plate of the base component a101 in a use installation state, and is bent towards the end of the base component a101 at the position adjacent to the back plate of the base component a101. And the other branch of the three-way structures a2233 and a2234 extends to the lower edge of the back plate of the base part a101 at the side where the back plate of the base part a101 is used in the mounting state and is bent toward the end of the base part a101 at the side close to the back plate of the base part a101. The angular frame is provided with a fixing structure, in this embodiment, a connecting pipe clamping groove is formed on the angular frame, and the extending part of the connecting pipeline is clamped in the connecting pipe clamping groove to play a role in fixing. The fixing structure fixes the position of the extending part of the connecting pipeline, and improves the safety of the pipeline in operation.
For the arrangement of the connection pipes (i.e. the collection of the liquid inlet pipe a2231 and the gas collecting pipe a 2232), the above embodiment may be adjusted according to the needs, and in the case that only one side needs to be provided with an external machine connection end for a specific user, only the pipe in the fin a220 needs to be connected to the liquid inlet pipe a2231 and the gas collecting pipe a2232 at a proper position on the corresponding side of the fin a 220.
In the case that two external machine connection ends are required to be provided, the connection pipelines in the above embodiment may be replaced by being connected to the side of the fin a220 close to the motor bracket. And the convenient installation and the convenient disassembly can be realized. In this case, however, if the end of the base member a101, which is far from the motor bracket side, is extended from the back plate adjacent to the base member a101 through one of the three-way structures a2233, a2234, by the length of the fin a220, it is necessary to arrange four pipes side by side at the side near to the motor bracket, thereby increasing the length of the heat exchange module and thus the overall length of the indoor unit. But there is no such problem if a solution is adopted in which one of the three-way structures a2233, a2234 extends over the length of the fin a220 from the fin a220 away from the base member a101. But after the appearance module is opened, an internal messy looking effect can be generated.
The evaporator of the embodiment mainly comprises a fin a220 formed with a plurality of refrigerant flow channels, wherein the refrigerant flow channels are sequentially connected through U-shaped pipes, the open ends of the U-shaped pipes are detachably provided with elbows so as to form a complete refrigerant flow channel, the refrigerant flow channel is provided with a refrigerant inlet and a refrigerant outlet which are arranged on the first side of the fin a220, and the evaporator also comprises a liquid inlet pipe a2231 and a gas collecting pipe a2232 which are respectively connected with the refrigerant inlet and the refrigerant outlet; the plurality of follow-up liquid pipes a2231 and the gas collecting pipes a2232 summarize one total liquid inlet pipe a2231 and one total gas collecting pipe a2232 through the liquid separating head a4 and the gas collecting head a 5. In this embodiment, it is preferable that the fin a220 and the liquid inlet pipe a2231 and the gas outlet pipe a2232 provided thereon are provided on the same side of the base member a101 so that the fin a220 can be assembled to the base member a101 from top to bottom. The meaning of arranging the fin a220, and the liquid inlet pipe a2231 and the gas collecting pipe a2232 thereon at the same side of the base member a101 at the same time is that: after the fin a220, the liquid inlet pipe a2231 and the gas collecting pipe a2232 are formed into an assembly, when the assembly is assembled with the bottom shell a310, the liquid inlet pipe a2231 and the gas collecting pipe a2232 are not required to be broken off to the other side of the bottom shell a310, so that the installation steps are simplified, and particularly, the liquid inlet pipe a2231 and the gas collecting pipe a2232 are not required to be manually bent, and the liquid inlet pipe a2231 and the gas collecting pipe a2232 are bent back to a design angle after the assembly is completed, so that the assembly is suitable for mechanical automatic assembly, the production efficiency is improved, and the production cost is reduced. In particular, referring to fig. 1, 2 and 3, the evaporator may be directly assembled to the bottom chassis a310 from top to bottom.
It should be noted that: the top-down assembly of the evaporator to the bottom case a310 means: after the base member a101 is fixed, the evaporator may be directly mounted to the base member a101 from the front surface of the base member a101. For example, when the base member is disposed horizontally as in the form of fig. 1, the evaporator is assembled from top to bottom as shown, and when the base member is placed vertically, the evaporator member can be mounted horizontally to the base member a101.
On the other hand, when the conventional air conditioner is installed, since the joint connecting the liquid inlet pipe a2231 and the gas collecting pipe a2232 with the outdoor unit is located at the rear side of the base member a101, the base member a101 needs to be kept in a forward-supporting state to complete the connection during installation, and in the above embodiment, the liquid inlet pipe a2231 and the gas collecting pipe a2232 are obviously located at the front side of the base member a101 together with the evaporator, so that the base member a101 does not need to be supported forward during installation. The evaporator unit may be mounted to the base unit a101 from top to bottom, or to the base unit a101 from bottom to top, or to the base unit a101 from left to right, based on the left view of the air conditioner in use of fig. 2, that is: the evaporator member can be mounted to the base member a101 from the front side of the base member a101.
In this embodiment, the bottom shell a310 is provided with a water tank a312 corresponding to the front and rear sides of the evaporator, the evaporator (i.e., the fin a 220) is connected with a liquid inlet pipe a2231 and a gas collecting pipe a2232, and the liquid inlet pipe a2231 and the gas collecting pipe a2232 are bent and arranged in the water tank a 312. In this way, in the operation process of the air conditioner, after the evaporator contacts with the air carrying the water vapor, the water vapor is condensed on the surface of the evaporator and is collected into the water tank a312 along the surface of the evaporator, and after the liquid inlet pipe a2231 and the gas collecting pipe a2232 extend into the water tank a312, the water in the water tank a312 can be further cooled, so that the refrigerant in the liquid inlet pipe a2231 and the gas collecting pipe a2232 is prevented from generating unnecessary heat exchange with the outside, and the energy efficiency ratio of the air conditioner is improved. Further, the water vapor has lower temperature after condensation, so that the cold insulation effect on the liquid inlet pipe a2231 and the gas collecting pipe a2232 is further improved; meanwhile, condensed water always exists in the water tank a312, so that the cold insulation effect on the liquid inlet pipe and the gas collecting pipe is not easy to be reduced in long-term use.
In this embodiment, the fin a220 is connected with a liquid inlet pipe a2231 and a gas collecting pipe a2232, and the liquid inlet pipe a2231 and the gas collecting pipe a2232 are two groups, and extend out of the shell of the evaporator towards two sides of the fin a220 respectively. Through the above embodiment, the liquid inlet pipe a2231 and the gas collecting pipe a2232 can be connected to the outdoor unit connection pipe at both sides of the evaporator, thereby being beneficial to reducing the pipe breaking step during installation. Specifically, when a user installs the air conditioner, the operator can select a proper side to be directly connected with the connecting pipe of the outdoor unit, so that the pipe breaking step of breaking the connecting pipe to the other side of the air conditioner is omitted.
It should be noted that: the liquid inlet pipe a2231 and the gas collecting pipe a2232 may be arranged in one group or two groups, and when the liquid inlet pipe a2231 and the gas collecting pipe a2232 are arranged in one group:
as a preference to the above embodiment, the liquid inlet pipe a2231 and the gas collecting pipe a2232 are connected to the first side of the fin a220, and protrude from the first side of the fin a220 to the air conditioning case; or may be connected to the first side of the fin a220, and bent to extend out of the air conditioning case from the second side of the fin a 220.
Specifically, the liquid inlet pipe a2231 and the gas collecting pipe a2232 are connected to the first side of the fin a220, and there are two types of outlet pipe forms extending from the first side of the fin a220 to the air conditioning case:
1. the liquid inlet pipe a2231 and the gas collecting pipe a2232 are connected to the first side of the fin a220, and are bent upwards along the contour of the fin a220 to be close to the bottom shell a310, then are bent downwards along the contour of the bottom shell a310, and then are bent towards the first side of the fin a220, so that the liquid inlet pipe a2231 and the gas collecting pipe a2232 extend out of the shell of the evaporator.
2. As an alternative to the above embodiment, the liquid inlet pipe a2231 and the gas collecting pipe a2232 are bent downward away from the bottom case a310 along the contour of the fin a220, and then bent toward the first side of the fin a 220.
Because the inside of the cavity formed between the base component a101 and the evaporator shell can be used for arranging components such as a motor, the two pipe outlet forms are adopted, so that the liquid inlet pipe a2231 and the gas collecting pipe a2232 respectively run along the outlines of the base component a101 and the evaporator shell, the liquid inlet pipe a2231 and the gas collecting pipe a2232 are prevented from occupying available space, and the structural design of the air conditioner is optimized.
When the liquid inlet pipe a2231 and the gas collecting pipe a2232 are arranged in two groups:
as a preferred embodiment: the first group of liquid inlet pipes a2231 and gas collecting pipes a2232 are connected to the first side of the fin a220, three-way structures a2233 and a2234 are respectively arranged on the first group of liquid inlet pipes a2231 and gas collecting pipes a2232, and the second group of liquid inlet pipes a2231 and gas collecting pipes a2232 are respectively connected with the two three-way structures a2233 and a2234, so that the second group of liquid inlet pipes a2231 and gas collecting pipes a2232 are connected with the first group of liquid inlet pipes a2231 and gas collecting pipes a2232. At this time, the first group of the liquid inlet pipes a2231 and the gas collecting pipes a2232 protrude toward the first side of the fin a220, and the second group of the liquid inlet pipes a2231 and the gas collecting pipes a2232 extend from the connection position toward the second side of the fin a220 and protrude from the second side of the fin a220 toward the air conditioning case.
Specifically, at this time, the second set of liquid inlet pipes a2231 and the gas collecting pipes a2232 have multiple running forms, and different running forms can have different effects, and the following is exemplified in conjunction with fig. 4, 5, 6, 7, 8, and 9:
the specific method is as follows: the fin a220 is formed by sequentially connecting a plurality of folding fins, wherein the first folding fin is arranged close to the base part a101, and the last folding fin is farthest from the base part a 101; after the liquid inlet pipe a2231 and the gas collecting pipe a2232 extend to the second side of the fin a220, they are bent and then extend to the second side of the fin a 220.
As a preferred embodiment, the second set of intake pipes a2231 and collector pipes a2232 extend from the upper part of the fin a220 (in particular the upper part of the first folded fin) to the first set of intake pipes a2231 and collector pipes a2232 extending from the second side of the fin a 220. And preferably, the second group of liquid inlet pipes a2231 and gas collecting pipes a2232 are obliquely arranged along the top surface of the evaporator at an angle of 0-10 degrees with respect to the horizontal direction, and the part of the second group of liquid inlet pipes a2231 and gas collecting pipes a2232 crossing the top surface of the first folded evaporator. Specifically, as shown in fig. 7, the second group of liquid inlet pipes a2231 and the gas collecting pipes a2232 may extend on the top surface of the evaporator at inclination angles of 0 °, i.e., horizontal, 1 °, 2 °, 3 °, 4 °, 5 °, 6 °, 7 °, 8 °, 9 °, 10 °. Wherein, inclination means: the second set of intake pipes a2231 and the air collection pipes a2232 form an angle with the bottom shell a 310.
As a preferred embodiment, the second group of liquid inlet pipes a2231 and gas collecting pipes a2232 are bent at the second side of the fin a220 along the contour of the fin a220 upwards to be close to the bottom shell a310, then bent downwards along the contour of the bottom shell a310, and then bent towards the first side of the fin a220, so as to extend out of the shell of the evaporator.
