Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to an outdoor unit and an air conditioner. BACKGROUND

[0002] The electric control device in the air conditioner generates heat energy when running, and the excessive heat energy will affect the normal operation of the electric control device. Usually, air cooling is used to dissipate heat from the electric control device. Specifically, the wind field is generated by rotating the fan blade, so that the airflow inside the outdoor unit flows through the heat exchanger to take away the heat energy on the heat exchanger, thereby reducing the temperature of the electric control device. However, in the refrigeration mode, the ambient temperature of the outdoor unit is high, and the air temperature further rises after the airflow passes through the heat exchanger. At the same time, the wind field in the cabinet itself will produce turbulence, and the air volume flowing through the heat exchanger is affected, which greatly reduces the heat dissipation efficiency of the heat exchanger.

[0003] In the related art, in order to improve the heat dissipation efficiency, the airflow inside the outdoor unit is improved to guide the air from the outside of the outdoor unit. Usually, the air is guided from the front panel, and a wind guide cover is arranged to connect the front panel and the heat exchanger to guide the external air to the heat exchanger for heat dissipation. Due to the installation and debugging requirements of the electric control assembly, the front panel needs to be frequently disassembled. The wind guide cover and the front panel are fixedly connected, which is very inconvenient. The distance between the wind guide cover and the front panel is fixed and cannot be adjusted at will, so that the application range of the wind guide cover is narrow and the flexibility is poor. When there is a gap between the wind guide cover and the front panel, the efficiency of the external airflow entering the outdoor unit for heat dissipation will be reduced.

[0037] In this application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation described herein as exemplary is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented for purposes of illustration and description. Details of the description can be replaced by alternatives without departing from the scope of the application. In the following description, for the purposes of explanation, specific details are set forth in order to provide a thorough understanding of the application. It will be apparent to one skilled in the art, however, that the application can be practiced without using these specific details. In other instances, well-known structures and processes are not elaborated upon in order to avoid obscuring the description of the application. Thus, the present application is not intended to be limited by the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0038] For the purpose of understanding the scheme of the present application, the spline curves and arrows used in the reference signs of the drawings are described as follows: the components indicated by the spline curves without arrows are solid components, i.e., components having a solid structure; and the components indicated by the spline curves with arrows are virtual components, i.e., components having no solid structure.

[0039] In the first aspect, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application provides an outdoor unit 100, which comprises: an outdoor housing 10 comprising an air inlet side wall 11, the air inlet side wall 11 being provided with an air inlet 111, the outdoor housing 10 defining a containing cavity 12, the containing cavity 12 being provided with an electric control assembly 13 and a heat dissipation assembly 14, the heat dissipation assembly 14 being connected to an end of the electric control assembly 13 away from the air inlet side wall 11; and an air guide assembly 20 comprising a connected air guide housing 21 and an extension structure 22, an end of the air guide housing 21 away from the extension structure 22 facing the heat dissipation assembly 14, the extension structure 22 being compressible or stretchable to abut an end of the extension structure 22 away from the air guide housing 21 against the air inlet side wall 11 and connect the air inlet 111.

[0040] It should be noted that the distance between the air guide housing 21 and the air inlet 111 is determined by the distance between the electric control assembly 13 and the first side wall, and the width of the electric control assembly 13 and the heat dissipation assembly 14, so that when the electric control assembly 13 or the heat dissipation assembly 14 is replaced, or the position of the electric control assembly 13 installed in the containing cavity 12 is changed, the distance between the air guide housing 21 and the air inlet 111 will be changed.

[0041] The outdoor unit 100 provided in the application is characterized in that the air inlet 111 is arranged on the air inlet side wall 11 of the outdoor unit 100, air is introduced from the outside of the outdoor unit 100 for heat dissipation, the temperature of the air flowing through the heat dissipation assembly 14 is reduced, the influence of the air turbulence in the containing cavity 12 is reduced, the actual air volume flowing through the heat dissipation assembly 14 is increased, the heat dissipation efficiency of the heat dissipation assembly 14 is improved, the use environment of the electric control assembly 13 is safer, and the reliability of the electric control is improved; the telescopic structure 22 is arranged to connect the air inlet 111 and the air guide shell 21, one end of the telescopic structure 22 is abutted against the air inlet side wall 11, so that the air entering the air inlet 111 can flow to the air guide shell 21 and the heat dissipation assembly 14 through the telescopic structure 22, the sealing effect of the air flow through the air duct is ensured, the heat dissipation effect on the heat dissipation assembly 14 is improved, and the telescopic structure 22 can be adaptively compressed or stretched according to the distance between the air guide shell 21 and the air inlet 111, so that the air guide assembly 20 is suitable for a wide range of outdoor unit shells 10, electric control assemblies 13 and heat dissipation assemblies 14; in addition, when the air inlet side wall 11 needs to be disassembled, the telescopic structure 22 is abutted against the air inlet side wall 11, the air inlet side wall 11 can be directly disassembled, and no additional connecting piece needs to be disassembled with the air guide assembly 20, so that the efficiency is improved.

[0042] In some embodiments of the application, please refer to Figure 5 and Figure 6 The air guide shell 21 comprises an air inlet end 2121, an air guide cavity 2122 and an air outlet end 2123 connected in sequence, and the air outlet end 2123 faces the heat dissipation assembly 14.

[0043] In some embodiments of the application, the telescopic structure 22 comprises a plurality of elastic members 23 arranged on the periphery of the air inlet end 2121, and a telescopic air pipe 24 arranged on the periphery of the plurality of elastic members 23, both ends of the elastic member 23 are connected to the air inlet end 2121 and abut against the air inlet side wall 11, and the telescopic air pipe 24 connects the air inlet 111 and the air inlet end 2121.

[0044] It should be noted that the number of elastic members 23 can be adaptively increased or decreased according to the size of the air inlet 111, and the shape of the pipe opening of the telescopic air pipe 24 can be adapted to the air inlet 111 and the air inlet end 2121.

[0045] In some embodiments of the application, the material of the telescopic air pipe 24 can be aluminum foil, canvas, etc., so that the telescopic air pipe 24 can have a certain strength to allow the air flow entering the air inlet 111 to pass through, ensure the sealing of the air flow duct, and be compressed or stretched when subjected to external force to adjust the length to adapt to the distance between the air inlet end 2121 and the air inlet 111.

[0046] In some embodiments of the present application, the elastic member 23 comprises a spring 231. Specifically, the spring 231 can be a coil spring 231, which is simple in structure and low in cost. One end of the coil spring 231 is connected to the air inlet end 2121, and the other end abuts against the air inlet side wall 11. When the distance between the air inlet end 2121 and the air inlet 111 is short, the coil spring 231 can be compressed to reduce its length, and is connected between the air inlet end 2121 and the air inlet 111. When the distance between the air inlet end 2121 and the air inlet 111 is long, the coil spring 231 can recover the elastic deformation to increase its length, and is connected between the air inlet end 2121 and the air inlet 111.

[0047] In some embodiments of the present application, referring to Figure 7 and Figure 8 , the elastic member 23 further comprises a first tube body 232 and a second tube body 233 arranged oppositely. The first tube body 232 comprises a first through tube 2321 and a first end face 2322 sealing one end of the first through tube 2321. The second tube body 233 comprises a second through tube 2331 and a second end face 2332 sealing one end of the second through tube 2331. The diameter of the first through tube 2321 is smaller than that of the second through tube 2331, so that the first through tube 2321 can slide in the second through tube 2331. It should be noted that oppositely arranged means that the first tube body 232 faces the second tube body 233, and both the first tube body 232 and the second tube body 233 are located between the first end face 2322 and the second end face 2332.

[0048] Further, the spring 231 is sleeved outside the second through tube 2331, and the outer diameter of the spring 231 is smaller than that of the first end face 2322 and the second end face 2332. The first through tube 2321 slides in the second through tube 2331, so that the first end face 2322 compresses or stretches the spring 231. When the distance between the air inlet end 2121 and the air inlet 111 is short, the first end face 2322 is pressed by the air inlet side wall 11 and moves towards the second end face 2332, so that the first end face 2322 presses the spring 231 to compress and shorten the distance of the telescopic structure 22. When the distance between the air inlet end 2121 and the air inlet 111 is long, the spring 231 recovers the elastic deformation to push the first end face 2322 to move towards the air inlet side wall 11, thereby increasing the distance of the telescopic structure 22.

[0049] It should be noted that the telescopic air pipe 24 is located between the first end surface 2322 and the second end surface 2332 and is clamped to the first end surface 2322 and the second end surface 2332. When the first end surface 2322 moves, it will push the telescopic air pipe 24 to move, so that the telescopic air pipe 24 adaptively adjusts the length. In other words, the pipe adjustment adjusts the distance between the first end surface 2322 and the second end surface 2332, which can adjust the length of the spring 231 and the length of the telescopic air pipe 24. The first pipe body 232, the spring 231 and the telescopic air pipe 24 move synchronously. The spring 231 can ensure automatic rebound when it is necessary to increase the length of the telescopic structure 22. The telescopic air pipe 24 can adaptively adjust the length to ensure the sealing of the air flow channel, so that the air flow outside the outdoor unit 100 cannot enter the containing cavity 12 and mix with the original gas in the containing cavity 12, thereby preventing the heat dissipation assembly 14 from being cooled by the air guide shell.

[0050] In some embodiments of the present application, the first pipe 2321 is provided with a sliding groove 2323 extending in the sliding direction of the first pipe 2321, and the second pipe 2331 is provided with a limiting hole 2333. The elastic member 23 further comprises a plug 234, the plug 234 passes through the limiting hole 2333 and the sliding groove 2323, and the plug 234 slides in the sliding groove 2323 to limit the sliding distance of the first pipe 2321. It can be understood that during the sliding of the first pipe 2321 in the second pipe 2331, the plug 234 slides synchronously in the sliding groove 2323. The sliding distance of the plug 234 in the sliding groove 2323 determines the sliding distance of the first pipe 2321 in the second pipe 2331. Through the setting of the plug 234, the sliding of the first pipe can be limited, and the plug 234 can also effectively connect the first pipe 232 and the second pipe 233, so as to prevent the first pipe 232 from falling off from the second pipe 233 during sliding, thereby improving the stability and reliability of the elastic member 23.

[0051] In some embodiments of the present application, the first end surface 2322 abuts against the air inlet side wall 11, the second end surface 2332 is provided with a first connecting part 2334, the air inlet end 2121 is provided with a second connecting part 2124, and the first connecting part 2334 and the second connecting part 2124 are fixedly connected. The air guide shell 21 and the telescopic structure 22 can be connected by conventional connection methods in the art, such as buckle connection, plug connection, bolt connection, adhesive connection, etc.

[0052] Exemplarily, in a specific embodiment, the first connecting part 2334 is a first connecting hole, the second connecting part 2124 is a second connecting hole, and the telescopic structure 22 further comprises a first fastener, the first fastener passes through the first connecting hole and the second connecting hole, and fixedly connects the air inlet end 2121 and the elastic member 23.

[0053] It should be noted that the material of the air guide shell 21 can be sheet metal, which can improve the strength of the air guide shell 21. The material of the air guide shell 21 can also be plastic, which is convenient for processing and preparation, and reduces production cost.

[0054] In some embodiments of the present application, the air guide shell 21 includes a first section 211 and a second section 212 connected, the air inlet end 2121, the air guide cavity 2122 and the air outlet end 2123 are arranged on the second section 212, and the air outlet end 2123 faces the bottom of the heat dissipation assembly 14. The first section 211 and the electric control assembly 13 define a heat dissipation cavity 131, and the heat dissipation assembly 14 is located in the heat dissipation cavity 131. It should be noted that the bottom of the heat dissipation assembly 14 refers to the lower side of the heat dissipation assembly 14 when the outdoor unit 100 is normally running. Specifically, in the vertical direction, the air inlet 111 is located below the electric control assembly 13, and the air guide assembly 20 transmits the air flow entering the air inlet 111 from below to the bottom of the heat dissipation assembly 14 to dissipate heat for the heat dissipation assembly 14. In addition, the first section 211 is arranged on the side of the heat dissipation assembly 14 away from the electric control assembly 13, so that the air flow flowing out of the second section 212 can flow to the heat dissipation assembly 14 as much as possible through the guidance of the first section 211, thereby effectively dissipating heat for the heat dissipation assembly 14.

[0055] In some embodiments of the present application, the first section 211 and the second section 212 are arranged obliquely. In other words, the first section 211 and the second section 212 are arranged at an angle, which can be an obtuse angle. Due to the distance between the electric control assembly 13 and the first side wall, and the width of the electric control assembly 13 and the heat dissipation assembly 14, there is a relatively long distance between the first section 211 and the air inlet 111. By arranging the second section 212 obliquely and towards the end close to the air inlet 111, the distance between the air inlet end 2121 and the air inlet 111 can be shortened, the burden of the telescopic structure 22 for conveying air flow can be reduced, and the oblique arrangement can shorten the distance from the air inlet end 2121 to the air outlet end 2123, shorten the air flow channel, and improve the conveying efficiency of the air flow.

[0056] In some embodiments of the present application, the heat dissipation assembly 14 can be a heat dissipation fin.

[0057] In some embodiments of the present application, the first section 211 is provided with a third connecting part 2111, and the electric control assembly 13 is provided with a fourth connecting part. The third connecting part 2111 and the fourth connecting part are fixedly connected to define the heat dissipation cavity 131. The air guide shell 21 and the electric control assembly 13 can be connected by conventional connection methods in the art, such as buckle connection, bolt connection, adhesive connection, etc.

[0058] Exemplarily, in a specific embodiment, the third connecting part 2111 is a third connecting hole, the fourth connecting part is a fourth connecting hole, and the outdoor unit 100 further comprises a second fastener, the second fastener passing through the third connecting hole and the fourth connecting hole to fixedly connect the first section 211 and the electric control assembly 13. The material of the shell of the electric control assembly 13 is usually sheet metal, and the material of the first section 211 can also be sheet metal. By connecting the third connecting hole and the fourth connecting hole through the second fastener, the connection stability of the electric control assembly 13 and the first section 211 can be improved.

[0059] In some embodiments of the present application, a crossbeam is arranged in the accommodating cavity 12, and the electric control assembly 13 is hung on the crossbeam. Specifically, the crossbeam is arranged in the accommodating cavity 12 on the side close to the air inlet side wall 11. When the electric control assembly 13 needs to be maintained, the air inlet side wall 11 can be removed to maintain the electric control assembly 13.

[0060] In some embodiments of the present application, referring again to Figure 1 , the outdoor unit 100 further comprises a fan 15 arranged in the accommodating cavity 12, and the fan 15 is arranged on the side of the heat dissipation assembly 14 away from the air inlet 111.

[0061] Specifically, taking the state of normal operation of the outdoor unit 100 as an example, the fan 15 is located at the top of the accommodating cavity 12, the electric control assembly 13 is located on the side close to the fan 15 in the accommodating cavity 12, the heat dissipation assembly 14 is located on the side away from the air inlet side wall 11 of the electric control assembly 13 to dissipate heat for the electric control assembly 13, and the air inlet 111 is located below the electric control assembly 13 on the air inlet side wall 11. When the fan 15 rotates, negative pressure is generated. The airflow outside the outdoor unit 100 enters the accommodating cavity 12 through the air inlet 111 and flows from bottom to top along the telescopic structure 22 and the air guide shell 21 to efficiently dissipate heat for the heat dissipation assembly 14.

[0062] In some embodiments of the present application, the air inlet 111 can be provided with a louver structure or a filter screen structure to filter the gas entering the accommodating cavity 12 from outside the outdoor unit 100, so as to avoid the accumulation of impurities in the accommodating cavity 12 to affect the performance of the outdoor unit 100.

[0063] In a second aspect, the embodiments of the present application further provide an air conditioner, which comprises the above-mentioned outdoor unit 100.

[0064] The above has described the basic concept. Obviously, for those skilled in the art, the above detailed disclosure is only taken as an example, and does not constitute a limitation on the present application. Although it is not explicitly stated here, those skilled in the art can make various modifications, improvements and corrections to the present application. Such modifications, improvements and corrections are suggested in the present application, so such modifications, improvements and corrections still belong to the spirit and scope of the exemplary embodiments of the present application.
