Description

Technical Field

[0001] This utility model relates to the field of air conditioner condenser technology, specifically to a condenser rotating structure and an air conditioner. Background Technology

[0002] With the development of refrigeration technology, there are increasingly more types of air conditioners. These include not only room air conditioners for people, but also air conditioners for equipment. These equipment air conditioners have requirements for high stability and high reliability. Because some equipment generates large heat loads and is often used in areas with high ambient temperatures, the operating temperature of the equipment is prone to rise. In high-temperature environments, the performance of the equipment deteriorates sharply, and high temperatures accelerate the aging of components. Therefore, it is extremely important to use air conditioning to properly control the operating temperature of the equipment.

[0003] In high-altitude areas, strong winds are common. When air conditioning equipment operates in such windy conditions, the condenser fan may face the strong winds. When the wind is too strong, the condenser fan may reverse. In this situation, the net air volume passing through the condenser for heat exchange drops sharply, and the motor temperature rises. This not only increases the condenser temperature, affecting the cooling effect, but can even cause the motor to burn out due to excessive heat, seriously affecting the normal operation of the equipment.

[0004] Therefore, the existing technology needs further improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, a condenser rotating structure and air conditioner are proposed. This solves the problem that in existing technologies, the condenser fan reverses when the airflow is too strong. In this case, the net air volume that exchanges heat through the condenser drops sharply and the motor temperature rises. This not only increases the condenser temperature, affecting the cooling effect, but can even cause the motor to burn out if the temperature gets too high.

[0006] To achieve the above objectives, the present invention proposes the following technologies:

[0007] A condenser rotating structure includes a support plate for supporting the condenser, a rotating shaft disposed below the support plate, and a conduit assembly disposed inside the rotating shaft. The rotating shaft and the conduit assembly are rotatably connected so that when the rotating shaft rotates with the support plate, refrigerant flows between the compressor and the evaporator through the conduit assembly.

[0008] Furthermore, the rotating shaft has a cavity inside, the conduit assembly is located in the cavity and is coaxially arranged with the rotating shaft, and the rotating shaft has a flow channel to communicate with the conduit assembly.

[0009] Furthermore, the conduit assembly includes a first conduit that connects a first chamber located at the top of the cavity to an evaporator below a rotating shaft, and the rotating shaft has a first flow channel that connects the first chamber to a compressor outside the rotating shaft.

[0010] Furthermore, the conduit assembly also includes a first column, the first conduit being located in a passageway opened within the first column, and the first column being rotatably connected to the inner wall of the rotating shaft via a first bearing.

[0011] Furthermore, the first bearing is located at the top of the first column, and a sealing structure is provided on the first bearing to achieve a seal between the first column and the rotating shaft, thereby forming a first chamber.

[0012] Furthermore, the conduit assembly also includes a second column, which has a hollow cylindrical structure to form a second conduit, with the first conduit located inside the second conduit.

[0013] Furthermore, the top end of the second pipe is connected to the second chamber between the first column and the second column, and a second flow channel is provided on the rotating shaft to connect the second chamber and the compressor.

[0014] Furthermore, the top end of the second column is rotatably connected to the rotating shaft via a second bearing, and a third bearing is provided between the bottom end of the first column and the rotating shaft, forming the second chamber between the second bearing and the third bearing.

[0015] Furthermore, a sealing plate is provided at the bottom of the second column, and a second interface connecting the second pipe is provided on the sealing plate. The first pipe passes through the sealing plate and has a first interface at its end.

[0016] Furthermore, the support plate is rotatably connected to the platform via a base located below it, and the support plate is in the shape of a bevel gear and is connected to the drive motor via a bevel gear transmission structure.

[0017] Furthermore, the surface of the condenser is provided with a pressure sensor for detecting wind pressure. The pressure sensor is connected to the drive motor to control the drive motor to rotate the support plate and the condenser to change their orientation according to the wind pressure received by the condenser.

[0018] An air conditioner comprising a condenser rotating structure as described in any of the preceding claims.

[0019] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0020] This application, by setting a rotating shaft and an internal duct assembly, allows the rotating shaft to rotate outside the duct assembly when the support plate drives the condenser to rotate. The duct assembly remains in a fixed position to ensure normal connection between the condenser and the evaporator, enabling the refrigerant to circulate among the components. Furthermore, when the condenser rotates, the connecting pipes between the outdoor and indoor units of the air conditioner remain stationary, achieving the purpose of allowing the outdoor unit to rotate. The rotation of the condenser prevents the fan from reversing and burning out the motor due to excessive natural wind, ensuring that the condenser can normally cool and dissipate heat for the equipment in windy weather.

Detailed Implementation

[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] like Figures 1 to 8 As shown, a condenser rotating structure includes a support plate 2 for supporting the condenser 1, a rotating shaft 3 is provided below the support plate 2, and a conduit assembly is provided inside the rotating shaft 3. The rotating shaft 3 is rotatably connected to the conduit assembly so that when the rotating shaft 3 rotates with the support plate 2, the refrigerant flows between the compressor and the evaporator through the conduit assembly.

[0033] By setting up the rotating shaft 3 and the internal conduit assembly, when the support plate 2 drives the condenser 1 to rotate, the rotating shaft 3 rotates outside the conduit assembly. The conduit assembly remains in a fixed position to ensure normal connection between the condenser and the evaporator, allowing the refrigerant to circulate in each component. As a result, when the condenser 1 rotates, the connecting pipe between the outdoor unit and the indoor unit of the air conditioner remains stationary, achieving the purpose of allowing the outdoor unit to rotate. The rotation of the condenser avoids the fan reversing and burning out the motor due to excessive natural wind, ensuring that the condenser can normally cool and dissipate heat for the equipment in windy weather.

[0034] In the condenser rotating structure of this embodiment, a cavity is provided inside the rotating shaft 3, the conduit assembly is located inside the cavity and is coaxially arranged with the rotating shaft 3, and a flow channel is provided on the rotating shaft 3 to communicate with the conduit assembly.

[0035] Specifically, a cavity is provided to accommodate the conduit assembly, and the condenser component or evaporator part outside the rotating shaft 3 is connected to the conduit assembly through the flow channel, thereby achieving communication and allowing the refrigerant to flow normally for refrigeration.

[0036] In the condenser rotating structure of this embodiment, the conduit assembly includes a first conduit 4, which connects the first chamber 5 located at the top of the cavity and the evaporator below the rotating shaft 3. The rotating shaft 3 has a first flow channel 6 to connect the first chamber 5 and the compressor outside the rotating shaft 3.

[0037] By setting up the first pipe 4, the first chamber 5 and the first flow channel 6, the three parts form a channel connecting the compressor in the evaporator and the condenser, which facilitates the refrigerant to flow between the evaporator and the compressor through the above three paths. After heat exchange in the evaporator, the refrigerant enters the first chamber 5 through the first pipe 4, and then flows out of the rotating shaft 3 through the first flow channel 6 and enters the compressor for compression.

[0038] Specifically, the first flow channel 6 is the compressor connection port, and the first chamber 5 is set to connect two pipes. The first chamber 5 is fixed at the top of the cavity and does not change with the rotation of the shaft 3. It plays the role of buffering and storing the refrigerant delivered from the evaporator through the first pipe 4. Then, it is connected to the compressor through the first flow channel 6 located on the periphery of the first chamber 5. The compressor connected to the first flow channel 6 rotates synchronously with the condenser 1 and the shaft 3, thereby sending the refrigerant into the compressor for compression.

[0039] In the condenser rotating structure of this embodiment, the conduit assembly further includes a first column 7, the first pipe 4 is located in a passage 8 opened inside the first column 7, and the first column 7 is rotatably connected to the inner wall of the rotating shaft 4 through a first bearing 9.

[0040] The first column 7 provides support for the first pipe 4 and is rotatably connected to the rotating shaft 3 through the first bearing 9, thereby fixing the position of the first pipe 4. The first column 7 and the first bearing 9 form a first chamber 5 between the top of the cavity to connect the first pipe 4 and the first flow channel 6.

[0041] Specifically, the first bearing 9 is located at the top of the first column 7, and a sealing structure is provided on the first bearing 9 to achieve a seal between the first column 7 and the rotating shaft 3, thereby forming the first chamber 5.

[0042] Preferably, the sealing structure includes sealing rings 20 respectively disposed between the rotating shaft 3 and the first bearing 9 and between the first column 7 and the first bearing 9 to achieve sealing. An end cap 10 is installed on the first bearing 9 to form a first chamber 5 to prevent refrigerant from leaking into the environment from the gap between the rotating shaft 3 and the first bearing 9 and between the first column 7 and the first bearing 9 due to poor sealing, thereby ensuring the sealing performance of the first chamber 5.

[0043] In the condenser rotating structure of this embodiment, the conduit assembly further includes a second column 11, which has a hollow cylindrical structure to form a second pipe, and the first pipe 4 is located inside the second pipe.

[0044] Specifically, the first column 7 and the second column 11 are coaxially arranged with the rotating shaft 3. The second column 11 is located below the first column 7. The second column 11 and the second pipe are connected to the throttling device and the evaporator in the condenser 1. The first pipe 4 is located inside the hollow structure of the second column 11 to avoid affecting the rotational connection between the second column 11 and the rotating shaft 3, and to ensure that the second column 11 remains fixed inside the rotating shaft 3.

[0045] In the rotating condenser structure of this embodiment, the top end of the second pipe is connected to the second chamber 12 between the first column 7 and the second column 11, and the rotating shaft 4 is provided with a second flow channel 13 to connect the second chamber 12 and the compressor.

[0046] Specifically, the second flow channel 13 is a throttling connection port. The second pipe, the second chamber 12, and the second flow channel 13 form a channel connecting the throttling device and the evaporator, realizing the refrigerant recirculation. After compression, condensation, and throttling, the refrigerant enters the second chamber 12 at the center of the rotating shaft 3 through the second flow channel 13, and then flows into the evaporator through the second channel. Similarly, the second chamber 12 acts as a buffer for the refrigerant flowing back from the condenser 1, avoiding the impact of the rotation of the rotating shaft 3 on the refrigerant flow.

[0047] In the condenser rotating structure of this embodiment, the top end of the second column 11 is rotatably connected to the rotating shaft 4 through the second bearing 14, and a third bearing 15 is provided between the bottom end of the first column 7 and the rotating shaft 4, forming the second chamber 12 between the second bearing 14 and the third bearing 15.

[0048] Specifically, sealing structures are provided on the second bearing 14 and the third bearing 15 to ensure the sealing effect of the second chamber 12 and prevent refrigerant leakage from affecting the flow of refrigerant between the condenser 1 and the evaporator. The first pipe 4 extends through the second chamber 12 and into the second column 11.

[0049] In the condenser rotating structure of this embodiment, a sealing plate is provided at the bottom end of the second column 11, and a second interface 16 communicating with the second pipe is provided on the sealing plate. The first pipe 4 passes through the sealing plate and has a first interface 17 at its end.

[0050] A sealing plate is used to separate the second pipe from the first pipe 4. The second pipe is connected through the second interface 16, and the first pipe 4 is connected through the first interface 17. At the same time, the first interface 17 and the second interface 16 are respectively connected to the evaporator. Specifically, the second interface 16 is the evaporator inlet, and the first interface 17 is the evaporator outlet. After being compressed by the compressor, heat exchanged by the condenser, and throttled by the throttling device, the refrigerant enters the second chamber 12 and the second pipe through the throttling connection port. It flows to the second interface 16 through the system pressure difference and gravity, and then enters the evaporator through the evaporator inlet for heat exchange. After heat exchange in the evaporator, it enters the first pipe 4 and the first chamber 5 through the first interface 17, and finally enters the compressor through the compressor connection port for compression.

[0051] With the above settings, when the shaft 3 rotates, the compressor, throttling device, fins and other auxiliary equipment in the entire condenser 1 rotate together at the same angular velocity, while the first column 7 and the second column 11 do not rotate due to the bearings. This prevents the first interface 17 and the second interface 16 from rotating. Consequently, when the condenser 1 rotates, the connecting pipe between the outdoor unit and the indoor unit of the air conditioner will not rotate, thus achieving the purpose of allowing the outdoor unit to rotate.

[0052] In the condenser rotating structure of this embodiment, the support plate 2 is rotatably connected to the platform via a base provided below. The support plate 2 is in the shape of a bevel gear and is connected to the drive motor 18 via a bevel gear transmission structure.

[0053] Specifically, the platform supports the condenser 1. The base can be a slider rail structure or other internal structure that allows rotation on the platform. The support plate 2 acts as a driven bevel gear, and the active bevel gear meshes with the support plate 2. The drive motor 18 drives the active bevel gear to rotate forward and backward through the drive shaft, thereby driving the condenser 1 to rotate. The rotation of the motor 18 can be manually or automatically controlled to adapt to the wind direction of strong winds and avoid the fan motor burning out due to headwinds.

[0054] In the condenser rotation structure of this embodiment, a pressure sensor 19 for detecting wind pressure is provided on the surface of the condenser 1. The pressure sensor 19 is connected to the drive motor 18 to control the drive motor 18 to rotate the support plate 2 and the condenser 1 according to the wind pressure received by the condenser 1, thereby changing their orientation.

[0055] Specifically, pressure sensors 19 are installed on the front and back of condenser 1 respectively. Let the wind pressure generated by the fan of condenser 1 under normal conditions be A, and the wind pressure required for normal heat dissipation of condenser 1 be B (A>B). The wind pressure value of the front pressure sensor 19 is D1, and the wind pressure value of the back pressure sensor is D2.

[0056] Under normal conditions, when the values ​​of the front pressure sensor 19 (D1 < B and D2 < B) are both present, an electrical signal of 0 is generated, the drive motor 18 does not start, and the condenser 1 does not rotate, relying on the fan for heat dissipation. When D1 > B and D2 < B, an electrical signal of 1 is generated, the drive motor 18 starts, and the condenser 1 rotates. After rotating a certain angle, D2 > B, an electrical signal of 0 is generated, and the drive motor 18 stops rotating to prevent the fan from reversing and burning out. At this point, natural wind and the fan are used for heat dissipation, improving the heat dissipation efficiency of the condenser 1.

[0057] On the other hand, this application also proposes an air conditioner including a condenser rotating structure as described in any of the above embodiments. It is foreseeable that the air conditioner of this application includes all the beneficial effects of the condenser rotating structure in the above embodiments, which will not be elaborated further here.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0059] Although embodiments of the present invention have been shown and described in detail, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
