A further purpose of the utility model is to prevent the fan from throwing water onto the compressor during operation.

In particular, the air conditioner outdoor unit of the present utility model includes: a casing; a vertically extending partition arranged in the casing, and at least one ventilation hole is opened on it; a fan is arranged in the casing, and is located on the partition the first side of the partition; the compressor is arranged in the casing and is located on the second side of the partition, and the reactor of the compressor is fixed on the second side surface of the partition; and at least one baffle part is opposite to the ventilation holes one by one The baffle part and the first side surface of the partition are fixed to the partition at intervals, configured so that the air on the first side of the partition can only flow into the ventilation hole through the ventilation gap between the edge of the baffle part and the partition, and enter The second side of the bulkhead.

Optionally, ventilation gaps are formed between the upper and lower edges of the baffle part and the partition respectively.

Optionally, the baffle part includes: a vertical baffle opposite to the ventilation hole and spaced apart from the first side surface of the partition; The first side surface is bent and extended, and is fixedly connected to the first side surface of the separator.

Optionally, the vertical baffle is a flat plate parallel to the first side surface of the partition.

Optionally, the baffle part and the partition are an integral part made by an integral molding process.

Optionally, the bulkhead is a sheet metal part.

Optionally, there are multiple ventilation holes, and the heights of the multiple ventilation holes are all lower than the reactor.

Optionally, the height position of the lowest end of the reactor is higher than the top end of the compressor.

In the air conditioner outdoor unit of the present utility model, the reactor of the compressor is arranged on the second side surface of the partition, and the partition is provided with a ventilation hole, which can allow the wind of the fan located on the first side of the partition to enter through the ventilation hole. The second side of the partition cools the air around the reactor, reduces the temperature of the electric controller, and avoids the aging of the lines around the reactor and the reduction of life due to high temperature. Moreover, the baffle part provided at the ventilation hole only allows air to flow into the ventilation hole through the ventilation gap between the baffle part and the partition, and does not directly enter the ventilation hole along a direction perpendicular to the surface of the partition. In this way, when it rains, the water droplets thrown by the fan rotation will be thrown onto the baffle, and then flow down from the baffle along the two sides of the partition without falling on the compressor through the ventilation hole. In order to avoid water damage to the compressor.

Furthermore, in the outdoor unit of the air conditioner of the present invention, the height of the plurality of ventilation holes is lower than the reactor, and after some water droplets enter the second side of the partition through the ventilation holes, they will flow downward along the second side surface , and will not flow to the reactor, avoiding the risk of water entering the reactor.

detailed description

The outdoor unit of the air conditioner according to the embodiment of the present utility model will be described below with reference to FIG. 1 to FIG. 6 . In the description of the embodiments of the present invention, the orientations or positional relationships indicated by "front", "back", "upper", "lower", "top", "bottom", "inner", "outer" etc. are based on the attached The orientation or positional relationship shown in the figure is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as Limitations on the Invention.

Fig. 1 is a schematic top view of the internal structure of an air conditioner outdoor unit according to an embodiment of the present invention. As shown in Figure 1, the air conditioner outdoor unit 100 of the embodiment of the present invention can be an air conditioner outdoor unit that uses a vapor compression refrigeration cycle system for refrigeration, and generally includes a casing 10, a vertically extending partition 50, a fan 30 , compressor 60 and condenser 20 . Wherein, the casing 10 defines a receiving space, and is generally a rectangular structure whose lateral direction (ie, the left-right direction on the drawing) is longer than the width direction (ie, the front-to-back direction). The partition 50 is disposed in the casing 10 for separating the inner space of the casing 10 , and the partition 50 can be a sheet metal part. The blower 30 is disposed in the casing 10 and is located on the first side of the partition 50 (ie, side A shown in each figure), and the condenser is also located on the first side of the partition 50 . When the air conditioner outdoor unit 100 is running, the fan 30 blows air forward (the wind direction is shown by the solid arrow in FIG. 1 ), and the forced convection heat exchange between the air and the condenser 20 will be realized. The compressor 60 is disposed in the casing 10 on the second side of the partition 50 (ie, side B shown in each figure). The compressor 60 has a reactor 62 fixed on the second side surface of the partition 50 .

The outdoor unit of the air conditioner is usually installed in the open air, and because there are air inlets and air outlets in the area A where the condenser 20 and the fan 30 are located, it is inevitable that rainwater will enter in rainy days. Therefore, the utility model utilizes the separator 50 to separate the compressor 60 and the reactor 62 from the condenser 20 and the fan 30, so that the compressor 60 and the reactor 62 are located in a relative space surrounded by the separator 50 and the casing 10. In the sealed small space, avoid the reactor 62, the compressor 60 and other electrical components from being damaged by water. However, the narrow space and sealed environment in area B cause air circulation to be blocked, which will hinder the heat dissipation of the reactor 62, increase the operating temperature of the reactor 62, and cause its service life to be reduced or even malfunction.

Fig. 2 is a schematic diagram of the A-side structure of the partition according to one embodiment of the present invention; Fig. 3 is an enlarged view of C in Fig. 2; Fig. 4 is a B-side structure of the partition according to one embodiment of the present invention Figure 5 is an enlarged view of D in Figure 4. As shown in Figures 1 to 5, in order to solve the heat dissipation problem of the reactor 62, at least one ventilation hole 52 is provided on the partition 50 in the embodiment of the present utility model to allow the wind to flow from the first side of the partition 50 to the second side. two sides. In addition, at least one baffle portion 54 is provided on the partition 50 . The number of the baffle parts 54 is the same as the number of the ventilation holes 52 and are arranged opposite to the ventilation holes 52 one by one. The baffle part 54 is fixed to the partition 50 at intervals from the first side surface of the partition 50, and is configured so that the air on the first side of the partition 50 can only be ventilated between the edge of the partition 54 and the partition 50. The gap flows into the vent hole 52, into the second side of the partition 50, and cannot enter the vent hole 52 in a direction perpendicular to the first side surface. That is, the ventilation hole 52 is completely blocked by the baffle part 54 when viewing the ventilation hole 52 with a horizontal line of sight.

In this way, when it is raining, the water droplets (the direction of which is shown by the hollow arrow shown in Figure 1) thrown by the fan 30 will be thrown onto the baffle part 54, and most of them will pass from the baffle part 54 along the partition. The first side surface of the plate 50 flows downwards, and a small portion flows down along the second side surface of the partition plate 50 without falling on the compressor 60 through the ventilation hole 52 , thereby preventing the compressor 60 from being damaged by water.

In some embodiments, as shown in FIG. 2 and FIG. 4 , the number of ventilation holes 52 is multiple, and the height positions of the plurality of ventilation holes 52 are all lower than the reactor 62, or the height of the lowest end of the reactor 62 is The location is higher than the top of the compressor 60, making it a higher location. In this way, even if some water droplets enter the second side of the separator 50 through the ventilation hole 52 , they will not flow onto the reactor 62 when flowing down the second side surface, avoiding the risk of water entering the reactor 62 .

FIG. 6 is a schematic structural view of the baffle part in the partition shown in FIG. 3 . As shown in FIG. 3 , FIG. 5 and FIG. 6 , in some embodiments, the upper and lower edges of the baffle portion 54 and the partition plate 50 respectively form the aforementioned ventilation gaps. This makes it easier for the water droplets falling on the baffle portion 54 to flow downwards, so as to avoid excessive accumulation on the baffle portion 54 and flow to the second side of the baffle.

Specifically, the baffle part 54 may include a vertical baffle 542 and two flange parts 544 . Wherein, the vertical baffle 542 is opposite to the ventilation hole 52 and spaced apart from the first side surface of the partition 50 . The two flange portions 544 are respectively bent and extended from both sides of the vertical baffle 542 toward the first side surface of the partition 50 , and are fixedly connected to the first side surface of the partition 50 , so that the vertical baffle 542 The upper and lower edges form a ventilation gap with the first side surface of the partition 50 . Preferably, the baffle part 54 and the partition plate 50 are made as an integral part by integral molding process. In the embodiment shown in FIG. 3 , FIG. 5 and FIG. 6 , the vertical baffle 542 is a flat plate parallel to the first side surface of the partition 50 to facilitate design and manufacture.

In some alternative embodiments not shown in the drawings, the baffle part 54 can also be in other shapes as a whole, such as an arc-shaped plate whose axis extends vertically as a whole, and the arc-shaped plate has two straight sides parallel to each other and Two arc-shaped sides and two straight sides are fixed on the first side surface of the partition 50 , and the upper and lower sides and the first side surface of the partition 50 define the aforementioned ventilation gap.

So far, those skilled in the art should recognize that although a number of exemplary embodiments of the present invention have been shown and described in detail herein, they can still be used according to the present invention without departing from the spirit and scope of the present invention. Many other variations or modifications that conform to the principles of the utility model are directly determined or derived from the disclosed content of the new model. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
