It is an urgent problem to be solved.

In order to ensure the reliability of the operation of the outdoor unit, the design of the outdoor unit needs to ensure the separation of "water" and "electricity", that is, the arrangement position of all electrical components needs to be completely isolated from the influence of rainwater. Therefore, the arrangement position of the reactor can only be placed inside the compressor cavity, and the fan cavity is isolated from the compressor cavity by the partition plate.

Detailed ways

Referring to FIGS. 1 to 4 in combination, according to the embodiment of the present application, the outdoor unit includes a casing, a partition 1 is arranged inside the casing, and a fan cavity 2 and a compressor cavity 3 are also arranged in the casing. In order to separate the fan cavity 2 and the compressor cavity 3, a reactor 4 is arranged on the partition 1. The reactor 4 is located in the compressor cavity 3, directly arranged on the partition 1, and located at the upper position of the partition 1.

In the present application, the reactor 4 is directly arranged on the separator 1, and no additional installation components are required, so it can save the cost of prototype development due to the separate development of parts, and also save the need to separately fix the reactor 4. One more part is added, so the assembly efficiency can be improved and the assembly difficulty can be reduced. Since the reactor 4 of the present application is arranged in the upper position of the partition plate 1, the height of the fixed position of the reactor 4 can be made high, and there can be enough space to give way. Due to the design of the pipeline, a larger pipeline design space can be formed between the reactor 4 and the compressor 9, which can satisfy the trend length of the pipeline piece 10 and the gradual change of the pipeline without increasing the size of the casing. The design of rounded corners, etc., greatly reduces the problems of pipe breakage and liquid flow noise caused by the rapid movement of the pipeline, and can also leave enough clearance between the reactor 4 and the pipeline to avoid the occurrence of pipeline parts 10. The problem of interference with the reactor 4 improves the utilization rate of the interior space of the outdoor unit and improves the safety and reliability of the reactor 4 .

The outdoor unit also includes an outdoor heat exchanger 5 and a side plate 6. The partition plate 1 is arranged in the space formed by the outdoor heat exchanger 5 and the side plate 6, and separates the area enclosed by the outdoor heat exchanger 5 and the side plate 6. It is divided into fan chamber 2 and compressor chamber 3. Preferably, a sealed connection method can be adopted between the outdoor heat exchanger 5 and the side plate 6 to more effectively prevent rainwater from entering the space where the reactor 4 is located from the connection position of the outdoor heat exchanger 5 and the side plate 6. The device 4 forms a more effective electrical safety protection.

The traditional reactor 4 is arranged and fixed on the partition 1. In order to save the screws, it is generally realized by the fixing method of snap-fit screws. However, since the reactor 4 and the snap fit are sheet metal parts, in order to ensure the assembly Smooth and efficient, there will be a large assembly gap, but since the back of the reactor is the fan cavity, in rainy weather, the rainwater will be thrown to the back of the reactor 4, and then enter the reactor 4. .

The reactor 4 of the present application is fixed on the upper part of the compressor cavity 3, because the side plate 6 and the outdoor heat exchanger 5 are tightly fitted and attached to each other, and the side plate 6 and the outdoor heat exchanger 5 are fastened with each other by screws. The method is fixed, which better ensures the fit between the side plate 6 and the outdoor heat exchanger 5, and ensures the water blocking effect of the rear and back of the reactor 4 in the embodiment of the application, which can be achieved without adding any materials. To achieve the separation of water and electricity, compared with the traditional fixing method, it achieves efficient assembly, material saving, and higher electrical safety and reliability. Of course, in order to further improve the sealing effect there, a sealing gasket or glue, etc. may also be added at the connection position of the side plate 6 and the outdoor heat exchanger 5 .

The partition plate 1 includes a vertically arranged spacer 7 and a horizontally arranged lateral protrusion 8. The lateral protrusion 8 extends from the spacer 7 to the side away from the fan cavity 2, and the reactor 4 is arranged on the side protrusion. 8 , the lateral protrusions 8 are connected at the upper positions of the sides of the spacer 7 . Preferably, the extending direction of the lateral protruding portion 8 is the extending direction of the surface at the position adjacent to the outdoor heat exchanger 5, so that the lateral protruding portion 8 and the outdoor heat exchanger 5 form a smooth transition at the connecting position structure, the overall structure consistency is better. The top of the lateral protruding portion 8 can be flush with the top of the outdoor heat exchanger 5 , thus ensuring that the lateral protruding portion 8 is located at the uppermost part of the partition plate 1 , which can enable the reactor 4 to be installed at the maximum of the compressor chamber 3 . The height position further increases the distance with the pipeline piece 10 below to avoid interference with the pipeline piece 10 , and is also conducive to forming a larger heat dissipation space, which is conducive to the heat dissipation of the reactor 4 . By arranging the lateral protrusion 8 on one side of the spacer 7, the spacer 1 can be used to directly form the installation position of the reactor 4, and this position can be staggered from the spacer 7 where the electrical box 11 is located, avoiding the need for the reactor 4 to be connected to the spacer 7. The installation of the electrical box 11 on the same side results in a large installation space, so that the space at the installation position of the reactor 4 in the compressor chamber 3 is more fully utilized, so it is more conducive to realizing the lightweight of the outdoor unit. and miniaturization.

Preferably, the reactor 4 is arranged on the side of the lateral protrusion 8 away from the body of the fan cavity 2 , so that the reactor 4 can form a large enough interval with the spacer 7 after the lateral protrusion 8 is protruded, so that the The electrical box 11 can be smoothly installed on the partition 7 , so that the entire upper space of the compressor chamber 3 can be fully utilized, and the interference between the reactor 4 and the electrical box 11 will not be caused.

The side plate 6 is L-shaped, and the side plate 6 includes a first side plate and a second side plate, the first side plate is attached to the side of the outdoor heat exchanger 5, and the second side plate is arranged on the lateral protrusion 8 away from the side. On one side of the spacer 7, a predetermined gap is formed between the reactor 4 and the second side plate.

In order to ensure the separation of water and electricity, generally a sponge or a small injection molded part should be added to the fixed area of the reactor buckle corresponding to the separator 1 to wrap the buckle of the reactor 4 to prevent the rainwater from wetting the reactor. However, since the operating temperature of the reactor 4 is generally about 120 degrees, the sponge is generally slightly scorched, and the method of adding injection molded parts is not only inefficient but also costly.

In this embodiment, after the predetermined gap is formed between the reactor 4 and the second side plate, since sufficient space is formed between the reactor 4 and the compressor 9 and the pipeline piece 10 below at the same time, the reactor 4 can be An air flow path is formed on the peripheral side of 4, and the air flow path can be used to effectively dissipate heat to the reactor 4, thereby effectively avoiding the occurrence of the high temperature burning of the surrounding material of the reactor 4.

The reactor 4 is arranged on the side of the lateral protrusion 8 facing the compressor chamber 3 , so that the reactor 4 can be better arranged in the compressor chamber 3 .

A compressor 9 is arranged in the compressor chamber 3 , and the compressor 9 is connected to the outdoor heat exchanger 5 through a pipeline piece 10 , and the pipeline piece 10 includes a first connection section connected to the compressor 9 and a connection to the outdoor heat exchanger 5 . The second connecting section, the first connecting section is located below the lateral protrusion 8, and can form a sufficient piping space between the reactor 4 arranged on the upper part of the partition 1, so that the piping method is more free, and the piping design is more flexible.

Preferably, an interlayer is formed between the lateral protruding portion 8 and the side plate 6, and the second connecting section is arranged in the interlayer.

In this embodiment, the lateral protrusion 8 is attached to the inner side of the outdoor heat exchanger 5 facing the compressor cavity 3, and the side plate 6 is arranged on the side of the outdoor heat exchanger 5 away from the compressor cavity 3, so that An interlayer that is slightly smaller than the thickness of the outdoor heat exchanger 5 can be formed between the first side plate of the side plate 6 and the lateral protrusion 8, and the interlayer is facing the connecting pipeline of the outdoor heat exchanger 5, so it can be connected to the outdoor heat exchanger 5. The second connecting section connected to the outdoor heat exchanger 5 is arranged in the interlayer. Due to the existence of the lateral protrusions 8, the second connecting section and the reactor 4 can be easily separated, so the second connecting section and the reactor 4 can be effectively avoided. Interference occurs between the devices 4.

Since the operating temperature of the reactor 4 is as high as about 120 degrees, the larger the area near the reactor 4, the better the air circulation and the better the heat dissipation effect of the reactor 4. During operation, the wind enters the fan cavity 2 from the back of the outdoor heat exchanger 5, and since the rear and back of the reactor 4 is kept a large gap from the side plate 6, the side also maintains a large gap. The advantage of this is that , the wind from the rear enters through the rear of the reactor 4, and a circular circulation is generated around the reactor 4, which can accelerate the heat dissipation of the reactor 4, and because the reactor 4 is arranged above the compressor cavity 3, the space above With a larger space area, the upper air circulation is better ensured, and the situation that the reactor 4 is high temperature and scorched the surrounding materials can be better prevented.

The partition 1 is also provided with an electrical box 11 , and the electrical box 11 is arranged on the partition 7 and located in the compressor chamber 3 . In this embodiment, the reactor 4 and the electrical box 11 are respectively fixed on different parts of the partition plate 1, so that the two are fixed separately, so the reactor 4 can be installed in the box separately, so that it can be installed on the assembly line. The reactor 4 can therefore effectively avoid the problem that the terminals of the reactor 4 are broken during transportation. In addition, the reactor 4 can be transported separately, which not only occupies a smaller space, but also improves the transport efficiency.

A mounting structure is integrally formed on the partition plate 1, and the reactor 4 is fixedly arranged on the mounting structure. In this embodiment, the mounting structure can be directly processed and formed on the partition plate 1, or the mounting structure can be directly integrally formed on the partition plate 1, thereby saving the development of parts and reducing the number of parts.

Preferably, two bottom snaps 12 and at least one lateral snap 13 are provided on the partition plate 1 , the bottom of the reactor 4 is plugged on the bottom snap 12 , and the side of the reactor 4 passes through the lateral snap 13 Clamp in position.

In this embodiment, a lateral buckle 13 and a screw hole are provided on the partition plate 1 , one side of the reactor 4 is fastened and fixed by the lateral buckle 13 , and the other side is screwed and fixed by a screw 14 .

The bottom and outer parts of the two bottom snaps 12 are fixedly connected to the body of the partition 1 , so that limit stops can be formed on the bottom and both sides of the reactor 4 , and the lateral snaps 13 The position and the upper left and right positions form a limit, and with the fixing function of the screws 14 , the reactor 4 can be stably fixed with fewer screws.

In the present application, when the reactor 4 is installed, the reactor 4 can be inserted into the side clips 13 and the two bottom clips 12 in sequence by using the effect of the reactor 4's own gravity. The bottom snaps 12 are attached to each other and will not drop rapidly. The advantage of this is that the position of the reactor in the vertical direction has been determined, so the pipeline arrangement in the compressor chamber will be more free. After the position of the bottom clip 12 for fixing the reactor 4 is determined, the position of the reactor 4 is completely determined. As long as the design clearance is ensured, there is no worry about the collision between the pipeline and the reactor 4 . Moreover, due to the existence of the lateral buckles 13 and the fastening screws 14, the reactor 4 cannot be shaken from side to side, so that the reactor 4 can be effectively and reliably fixed.
