Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioning outdoor unit. Background Art

[0002] The fan cover is one of the important parts of the air conditioner outdoor unit. The fan cover can not only protect the fan blades and prevent indoor debris from accidentally entering and damaging the fan or causing accidents, but also make the gas inhaled by the fan more concentrated and focus the blown air, thereby improving the heat dissipation effect and achieving better cooling and heating effects.

[0003] Side-outlet air conditioner outdoor unit is a common type of air conditioner outdoor unit. In the side-outlet air conditioner outdoor unit, the air outlet of the casing is arranged on the front side of the casing, and the fan cover and the front panel of the casing cooperate with each other.

[0058] The air conditioner outdoor unit provided in this application may have various implementation forms. Figure 1-Figure 15 This is a specific implementation of the air conditioner outdoor unit of the present application.

[0059] like Figure 1 and Figure 2As shown, the air-conditioning outdoor unit provided in the present application includes a casing 100, and the casing 100 is used to form the overall appearance of the air-conditioning outdoor unit. The top of the casing 100 and the bottom of the casing 100 are opposite ends, and the height direction of the casing 100 is from the top of the casing 100 to the bottom of the casing 100; the left side of the casing 100 and the right side of the casing 100 are opposite sides, and the length direction of the casing 100 is from the left side of the casing 100 to the right side of the casing 100; the front side of the casing 100 and the back side of the casing 100 are opposite sides, and the direction from the front side of the casing 100 to the back side of the casing 100 is the thickness direction of the casing 100.

[0060] like Figure 2 As shown, the housing 100 includes a housing air inlet 101 , which is disposed at the outer periphery of the housing 100 , and air outside the housing 100 enters the interior of the housing 100 through the housing air inlet 101 .

[0061] In some embodiments, the casing air inlet 101 is disposed at the rear side of the casing 100 .

[0062] In other embodiments, the casing air inlet 101 is disposed on the rear side of the casing 100 and on the left side of the casing 100 and / or on the right side of the casing 100 to increase the air intake volume of the air conditioner outdoor unit.

[0063] In this embodiment, the casing air inlet 101 is opened at the rear side of the casing 100 and the right side of the casing 100 .

[0064] like Figure 4 As shown, the housing 100 includes a housing air outlet 102 , which is disposed at the front side of the housing 100 , and the air inside the housing 100 is output to the outside through the housing air outlet 102 .

[0065] like Figure 6 As shown, the air conditioner outdoor unit includes a heat exchanger 500, which is disposed inside the casing 100. The heat exchanger 500 is disposed close to the casing air inlet 101, and the heat exchanger 500 is used to exchange heat for the air passing therethrough.

[0066] In some embodiments, the heat exchanger 500 extends from the left side of the casing 100 through the rear side of the casing 100 to the right side of the casing 100, so that the heat exchange area of ​​the heat exchanger 500 can be maximized while the internal space of the casing 100 remains unchanged, thereby increasing the performance of the air conditioner outdoor unit.

[0067] like Figure 4 and Figure 6 As shown, the air conditioner outdoor unit includes a fan 400, which is disposed inside the casing 100, the fan 400 is located on the leeward side of the heat exchanger 500, and the fan 400 is disposed close to the casing air outlet 102.

[0068] Through the operation of the fan 400 , air outside the casing 100 enters the casing 100 through the casing air inlet 101 , and is output to the outside of the casing 100 through the casing air outlet 102 after heat exchange in the heat exchanger 500 .

[0069] In this embodiment, the fan 400 is an axial flow fan 400 .

[0070] like Figure 6 As shown, the air-conditioning outdoor unit includes a compressor 600, which is disposed inside the casing 100 and is used to drive the refrigerant to flow.

[0071] like Figure 1 and Figure 2 As shown, the air conditioner outdoor unit includes a fan cover 200, which is located at the air outlet 102 of the casing. On the one hand, the fan cover 200 can protect the fan 400 to prevent debris from entering the casing 100 through the air outlet 102 of the casing and contacting the fan 400, thereby affecting the normal operation of the fan 400; on the other hand, the gas inhaled by the fan can be more concentrated, thereby increasing the speed and pressure of the gas, and ultimately increasing the wind force output by the fan. In other words, the fan cover 200 can focus the blown air, improve the heat dissipation effect, and achieve better cooling and heating effects.

[0072] like Figure 4 As shown, the housing 100 includes a front panel 110 , the front panel 110 is located at the front side of the housing 100 , the housing air outlet 102 is opened on the front panel 110 , and the fan cover 200 is installed on the front panel 110 .

[0073] When the fan cover 200 is mounted on the front panel 110, a matching gap is defined between the fan cover 200 and the front panel 110. When snow accumulates on the top of the housing 100, melted snow water easily flows along the front panel 110 through the matching gap between the fan cover 200 and the front panel 110 into the housing 100. The snow water that enters the housing 100 drips under the action of gravity. When the ambient temperature of the housing 100 is low, the dripping snow water easily forms icicles, and the icicles may collide with each other when the fan 400 is running, resulting in adverse consequences.

[0074] Based on this, in this application, Figure 3As shown, the front panel 110 is provided with a mounting portion 111, and the mounting portion 111 is located at the outer edge of the air outlet 102 of the housing; the mounting portion 111 is recessed toward the inside of the housing 100; the fan cover 200 is arranged in the mounting portion 111 on the side facing the front panel 110, so that the matching gap between the fan cover 200 and the front panel 110 is arranged in the mounting portion 111, that is, the matching gap between the fan cover 200 and the front panel 110 is recessed in the front panel 110. When the melted snow water on the top of the housing 100 flows down along the front panel 110, the outer edge of the mounting portion 111 can block the snow water, thereby preventing the snow water from entering the inside of the housing 100 along the matching gap between the fan cover 200 and the front panel 110.

[0075] The front panel 110 is limited to form a front side surface, and the mounting portion 111 is recessed in the front side surface. When the fan cover 200 is disposed in the mounting portion 111, the fan cover 200 is disposed on a raised front side surface facing away from the interior of the casing 100. On the one hand, the space inside the casing 100 occupied by the mounting portion 111 recessed toward the interior of the casing 100 can be reduced, and on the other hand, the blocking effect of the outer edge of the mounting portion 111 on the air passing through the fan cover 200 can be reduced.

[0076] like Figure 7 As shown, the fan cover 200 includes a grille, which defines a plurality of vents 201 , which are connected to the interior of the housing 100 , and the air inside the housing 100 is output to the outside of the housing 100 through the vents 201 from the housing air outlet 102 .

[0077] In some embodiments, the middle portion of the grille is convex toward the front side of the housing 100 to increase the distance between the grille and the fan 400 along the thickness direction of the housing 100, thereby reducing the blocking effect of the grille on the air.

[0078] like Figure 7 and Fig. 9 As shown, the fan cover 200 includes a frame 240 , and the frame 240 is used to define the shape of the fan cover 200 . The grille is disposed in the frame 240 and connected to the frame 240 .

[0105] If α<5°, the upper surface of the water guide 300 is nearly a plane, and the water guiding effect of the water guide 300 is poor.

[0106] An angle α is defined between the upper surface of the water guide 300 and the horizontal plane, and the angle α satisfies the relationship: α≤60°, so as to prevent the water guide 300 from blocking the air passing through the fan cover 200 .

[0107] If α>60°, the inclination of the upper surface of the water guide member 300 is relatively large. If the size of the water guide member 300 along the horizontal direction is relatively large, the water guide member 300 is likely to block the air passing through the fan cover 200. If the size of the water guide member 300 along the horizontal direction is relatively small, the guiding path of the water guide member 300 along the horizontal direction is relatively short, and water can easily flow into the interior of the casing 100 through the grille.

[0108] like Fig.14 As shown, the height of the upper frame in the vertical direction is H1.

[0109] The height of the water guide 300 in the vertical direction is H2, and H2 and H1 satisfy the relationship: H2≤H1, so as to prevent the water guide 300 from extending to the grille in the vertical direction and blocking the air passing through the fan cover 200.

[0110] If H2>H1, the height of the water guide 300 is greater than the height of the frame 240, that is, the projection of the water guide 300 on the vertical plane partially overlaps with the projection of the grille on the vertical plane, and the water guide 300 may block the air passing through the grille.

[0111] like Fig.15 As shown, the distance between the outer edge of the frame 240 facing away from the interior of the casing 100 and the front side is L, and the distance between the side of the water guide member 300 away from the fan cover 200 and the front side is D. D and L satisfy the relationship: D≥L, so that the water guide member 300 has a sufficient guiding path, thereby guiding the water flow in a direction away from the interior of the casing 100.

[0112] It should be noted that, in some embodiments, the distance between the outer edge of the upper frame facing away from the interior of the casing 100 and the front side, the distance between the outer edge of the lower frame facing away from the interior of the casing 100 and the front side, the distance between the outer edge of the left frame facing away from the interior of the casing 100 and the front side, and the distance between the outer edge of the right frame facing away from the interior of the casing 100 and the front side may not be the same. Since the water guide member 300 is arranged on the upper frame, when the distance between the outer edge of the upper frame facing away from the interior of the casing 100 and the front side, the distance between the outer edge of the lower frame facing away from the interior of the casing 100 and the front side, the distance between the outer edge of the left frame facing away from the interior of the casing 100 and the front side, and the distance between the outer edge of the right frame facing away from the interior of the casing 100 and the front side are not the same, the distance from the side of the water guide member 300 away from the fan cover 200 to the front side must at least be greater than or equal to the distance between the outer edge of the upper frame facing away from the interior of the casing 100 and the front side, so as to ensure the guiding effect of the water guide member 300.

[0113] If D<L, the distance of the water guide 300 in the horizontal direction is shorter, the distance between the water flow guided by the water guide 300 and the grille is closer, and the water flow may enter the interior of the housing 100 through the grille.

[0114] The length direction of the water guide 300 is arranged along the length direction of the housing 100 , and two ends of the water guide 300 in the length direction are arranged corresponding to the two sides of the fan cover 200 adjacent to the top of the fan cover 200 .

[0115] like Figure 8 As shown, transition parts 310 are respectively provided at both ends of the water guide 300 in the length direction, and the end of the transition part 310 away from the water guide 300 is arranged toward the bottom of the casing 100, so that the water guide part can better guide water to flow downward.

[0116] The working principle of the above-mentioned air-conditioning outdoor unit is as follows: the fan cover 200 is installed on the installation part 111, and the matching gap between the fan cover 200 and the front panel 110 is located in the installation part 111. After the snow on the top of the casing 100 melts, the snow water flows downward along the front panel 110. Since the matching gap between the fan cover 200 and the front panel 110 is arranged in the installation part 111, the snow water is not easy to flow into the matching gap between the fan cover 200 and the front panel 110. The snow water flows along the front panel 110 to the water guide member 300, the snow water contacts the water guide member 300 and continues to flow along the upper surface of the water guide member 300, and the water guide member 300 guides the snow water in a direction away from the interior of the casing 100 to prevent the snow water from entering the interior of the casing 100, thereby preventing the formation of ice inside the casing 100, and further preventing the ice from affecting the operation of the fan 400.

[0117] The above-mentioned air-conditioning outdoor unit is provided with a mounting portion 111 on the front panel 110 of the casing 100, and the mounting portion 111 is recessed in the front side of the casing 100, so that a fitting gap formed when the fan cover 200 is connected to the front panel 110 is provided in the mounting portion 111. When the snow water melted from the snow accumulated on the top of the casing 100 flows along the front panel 110, the outer edge of the mounting portion 111 can block the snow water to prevent the snow water from entering the interior of the casing 100 along the fitting gap; and a water guide member 300 is provided on the side of the fan cover 200 away from the casing 100, and the water guide member 300 is used to guide the snow water generated by the melting of the snow accumulated on the top of the casing 100 in a direction away from the fan cover 200, to prevent the snow water from entering the interior of the casing 100 to generate icicles and affect the operation of the fan 400.

[0118] The above-mentioned air conditioner outdoor unit has high working reliability, the melted snow water on the top of the casing 100 is not easy to enter the inside of the casing 100, and icicles are not easy to form inside the casing 100. In cold seasons, the fan 400 has high operating reliability and is not easily affected by icicles.
