Further, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

Example 1

The embodiment provides an evaporator, which is an important component of the heat exchange heat module in the air conditioner, and the heat exchange module includes a fin a220 integrally supported by the both ends of the angle frame in an inverted U shape, and the fin a220 Sealing members are provided at both ends, thereby forming an open chamber in the inverted U-shape of the fins a220. The pipe in the fin a220 is connected to the outdoor unit through a connecting pipe composed of the inlet pipe a2231 and the header pipe a2232. In the present embodiment, three-way structures a2233 and a2234 are provided on the inlet pipe a2231 and the gas collection pipe a2232, and the outer joints of the connecting pipes are provided on both sides of the fins a220 through the three-way structures a2233 and a2234. end.

In this embodiment, the inlet pipe a2231 and the gas collection pipe a2232 are both connected to the side of the fin a220 away from the motor bracket, and one of the three-way structures a2233 and a2234 extends past the back plate of the base member a101. After the length of the fin a220, it is bent into a U-bend that bypasses the motor bracket from the side of the motor bracket away from the back plate of the base member a101, and the back plate that reaches the base member a101 uses the lower edge of the mounted state, and is close to The base member a101 is bent toward the end of the side base member a101 at the back plate. And the other side of the three-way structure a2233, a2234 extending to the back side of the side base member a101 uses the lower edge of the mounted state, and is bent toward the side base near the back plate of the base member a101. The end of the part a101. A fixing structure is provided on the angle frame. In this embodiment, the connecting tube card slot 211 is formed on the angle frame, and the extending portion of the connecting pipe is engaged in the connecting tube card slot a211 for fixing. The fixed structure fixes the position of the extension of the connecting pipe and improves the safety of the pipeline operation.

For the arrangement of the connecting pipelines (ie, the collection of the inlet pipe a2231 and the collecting pipe a2232), the above embodiment can be adjusted as needed, and only needs to be provided on the one side for the specific user. The appropriate position on the corresponding side of the fin a220 may be such that the pipe in the fin a220 is connected to the inlet pipe a2231 and the header pipe a2232.

In the case where it is necessary to provide the connection terminals of the external units on both sides, the connection lines in the above embodiments may be replaced with the ones connected to the side of the fins a220 close to the motor bracket. It can also be easily installed and removed. However, in this case, if one of the three-way structures a2233, a2234 is still used from the back plate adjacent to the base member a101, the length extending through the fin a220 reaches the end of the base member a101 away from the side of the motor bracket. Then, four pipelines arranged side by side on the side close to the motor bracket will increase the length of the heat exchange module, thereby increasing the overall length of the indoor unit. However, if a scheme is adopted in which one of the three-way structures a2233 and a2234 extends from the fin a220 away from the base member a101 and extends over the length of the fin a220, there is no such problem. However, after the appearance module is opened, there will be an internal messy look and see effect.

The evaporator of the embodiment is mainly composed of fins a220 formed with a plurality of refrigerant flow passages, and the refrigerant flow passages are sequentially connected by U-shaped tubes, and the open ends of the U-shaped tubes are detachably provided with elbows, thereby constituting a complete refrigerant flow passage having a refrigerant inlet and a refrigerant outlet disposed on a first side of the fin a220, and an inlet pipe a2231 and a gas collection pipe a2232 respectively connected to the refrigerant inlet and the refrigerant outlet; and a plurality of follow-up liquid pipes A2231 and the collecting pipe a2232 summarize a total inlet pipe a2231 and a total header a2232 through the liquid separation head a4 and the gas collection head a5. In the present embodiment, it is preferable that the fin a220 and the inlet pipe a2231 and the gas collecting pipe a2232 provided thereon are disposed on the same side of the base member a101 so that the fin a220 can be assembled from the top to the bottom to the base member a101. on. The meaning of the fin a220, the inlet pipe a2231 and the header pipe a2232 on the same side of the base member a101 at the same time is that the fin a220 and the inlet pipe a2231 and the gas collecting pipe a2232 After the assembly is assembled, when assembling with the bottom casing a310, it is not necessary to smash the inlet pipe a2231 and the gas collecting pipe a2232 to the other side of the bottom casing a310, so that the installation step is simplified, specifically, no manual need is required. The inlet pipe a2231 and the gas collecting pipe a2232 are bent, and are bent back to the design angle after assembly, so that it is suitable for mechanized automatic assembly, which helps to improve production efficiency and reduce production cost. Specifically, referring to FIG. 1, FIG. 2, and FIG. 3, the evaporator can be directly assembled to the bottom case a310 from top to bottom.

It should be noted that the assembly of the evaporator from the top to the bottom of the bottom case means that after the base member a101 is fixed, the evaporator can be directly mounted on the base member a101 from the front surface of the base member a101. For example, when the base member is horizontally disposed as shown in 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 horizontally mounted to the base member. On a101.

On the other hand, when the existing air conditioner is installed, the joint connecting the inlet pipe a2231 and the header pipe a2232 and the outdoor unit is located on the rear side of the base member a101, and the base member a101 needs to be held forward during the installation process. In the above embodiment, the inlet pipe a2231 and the header pipe a2232 are clearly located on the front side of the base member a101 together with the evaporator, so that the front support base member a101 is not required at the time of installation. Based on the left side view of the air conditioner use state of FIG. 2, the evaporator member may be mounted to the base member a101 from top to bottom, or from bottom to top to the base member a101, or from left to right to the base. On the part a101, that is, the evaporator part can be attached to the base part a101 from one side of the base part a101.

In this embodiment, the bottom shell a310 is provided with a water tank a312 corresponding to the front and rear of the evaporator, and the evaporator (ie, the fins a220) is connected with the liquid inlet tube a2231 and the gas collecting tube a2232, the liquid inlet tube a2231 and the gas collecting tube a2232. The bend is disposed in the water tank a312. Thus, during the operation of the air conditioner, the evaporator and the air carrying the water vapor contact the water vapor to condense on the surface of the evaporator, and collect along the surface of the evaporator into the water tank a312, and the inlet tube a2231 and the set After the gas pipe a2232 is inserted into the water tank a312, it can be further kept cold by the water in the water tank, thereby preventing unnecessary heat exchange between the refrigerant in the inlet pipe a2231 and the gas collection pipe a2232 and the outside, and contributing to the improvement of the air conditioner. Energy efficiency ratio. Further, after the water vapor condenses, it has a lower temperature. In addition, the cooling effect on the inlet pipe a2231 and the header pipe a2232 is further improved; at the same time, since the condensed water is always present in the water tank a312, the cooling effect on the inlet pipe and the gas collecting pipe is not easily lowered in long-term use.

In this embodiment, the fin a220 is connected to the inlet pipe a2231 and the gas collection pipe a2232, and the inlet pipe a2231 and the gas collection pipe a2232 are two groups, and respectively protrude the casing of the evaporator toward both sides of the fin a220. According to the above embodiment, the inlet pipe a2231 and the header pipe a2232 and the outdoor unit connecting pipe can be connected to both sides of the evaporator, thereby facilitating the reduction of the pipetting step at the time of installation. Specifically, when the user installs the machine, the appropriate side is directly connected to the outdoor unit connecting pipe, thereby eliminating the step of smashing the connecting pipe to the other side of the air conditioner.
