Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to a spherical electrode, a motor and an air conditioner. Background Art

[0002] The air conditioner mainly consists of four major components, namely the compressor, condenser, throttling device, and evaporator. The refrigerant circulates in the above four major components in turn to adjust the temperature in the room. During cooling, the low-pressure vapor of the refrigerant is sucked in by the compressor and compressed into high-pressure vapor and then discharged to the condenser. At the same time, the outdoor air sucked in by the outdoor axial flow fan flows through the condenser, taking away the heat released by the refrigerant, and condensing the high-pressure refrigerant vapor into high-pressure liquid; the high-pressure liquid is sprayed into the evaporator after passing through the filter and throttling mechanism, and evaporates at a corresponding low pressure, absorbing the surrounding heat; at the same time, the indoor cross-flow fan allows air to continuously enter the fins of the evaporator for heat exchange, and sends the air that becomes cold after releasing heat to the room, so that the indoor air circulates continuously to achieve the purpose of lowering the temperature.

[0003] Among them, the cross-flow fan of the indoor unit is widely used in air-conditioning equipment and small air supply equipment due to its excellent characteristics such as large flow, low noise, and smooth air supply. The impeller of the cross-flow fan is multi-blade, long cylindrical, and has forward multi-wing blades. During the operation of the current air conditioner, one end of the cross-flow fan is rotatably mounted on the casing, while the other end is driven to rotate by the main motor. However, it is difficult to install an additional motor on the cross-flow fan so that the additional motor rotates together with the main motor and outputs another rotational motion at the same time, because the existing motor is mainly powered by positive and negative leads. As the motor rotates, the leads will be entangled and broken, thereby hindering the possibility of rotating with the cross-flow fan. Summary of the invention

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "first" and "second" are for the purpose of clearly describing the numbering of product components and do not represent any substantial difference. "Up", "down", "left", "right", etc. are only used to indicate relative position relationships. When the absolute position of the described object changes, the relative position relationship may also change accordingly. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0055] It should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the invention can be understood in specific circumstances.

[0056] like Figures 1 to 5 As shown, a spherical electrode 300 provided in an embodiment of the present invention includes an insulating sphere 320 having a columnar through hole 321 therein and at least one conductive clamp 330, wherein the conductive clamp 330 is clamped on the inner wall surface and the outer wall surface of the insulating sphere 320 along the axial direction of the insulating sphere 320. The conductive clamp 330 includes an inner conductive sheet 331 and an outer conductive sheet 332 connected at one end, wherein one side of the inner conductive sheet 331 is attached to the inner wall surface of the insulating sphere 320, the other side of the inner conductive sheet 331 is cylindrical, and one side of the outer conductive sheet 332 is attached to the outer wall surface of the insulating sphere 320.

[0057] Specifically, the insulating sphere 320 can be a sphere or an ellipsoid, the upper and lower ends of the sphere (or ellipsoid) are truncated by a plane, and a cylindrical through hole is opened in the center thereof, forming a spherical shell with a spherical outer wall and a cylindrical inner wall. The conductive clamp 330 is clamped on the insulating sphere 320. The conductive clamp 330 can be an integral annular clamp wound around the circumference of the insulating sphere 320, or a plurality of separate arc-shaped clamps. Each conductive clamp 330 has the same shape and size, and includes an inner conductive sheet 331 and an outer conductive sheet 332. The lower ends of the inner conductive sheet 331 and the outer conductive sheet 332 are connected to form an integral component. When assembling, the conductive clamp 330 can be moved up from the lower end of the insulating sphere 320 and clamp the wall of the insulating sphere 320. One side of the inner conductive sheet 331 is attached to the inner wall surface of the insulating sphere 320, and the other side of the inner conductive sheet 331 is cylindrical, so a cylindrical conductive chamber can be formed inside the spherical electrode 300 for rotatably electrically connecting to the power supply shaft. The inner side of the inner conductive sheet 331 can also be coated with conductive lubricating oil or conductive lubricating glue. When in use, the outer conductive sheet 332 can be electrically connected to the power supply device, thereby transferring electrical energy to the inner conductive sheet 331 and then to the power supply shaft.

[0058] The spherical electrode 300 provided in this embodiment is clamped on the inner wall and outer wall of the insulating sphere 320 by forming an inner conductive sheet 331 and an outer conductive sheet 332 connected at one end. The spherical electrode 300 can be clamped in the fixed component through the outer conductive sheet 332. At the same time, the outer conductive sheet 332 can be electrically connected to an external power supply device, and the inner conductive sheet 331 can maintain rotational contact with the power supply shaft, thereby transmitting the electric energy of the external fixed power supply device to the rotating component.

[0059] Furthermore, if Figure 1 and Figure 2 As shown, the outer conductive sheet 332 of at least one conductive clip 330 is provided with a second terminal 310. Specifically, the second terminal 310 can be a conductive rod extending upward. By providing the second terminal 310, it can be extended out of the electrode mounting seat, so as to facilitate electrical connection to an external power supply device.

[0060] Furthermore, if Figure 1 , Figure 2 and Figure 3 As shown, there are multiple conductive clips 330, and the multiple conductive clips 330 are distributed at intervals along the circumference of the insulating sphere 320. Specifically, the multiple conductive clips 330 can be distributed at equal intervals along the circumference of the insulating sphere 320. It also includes an annular conductive sheet 340, which is installed at one end of the insulating sphere 320 facing the connecting portion of the inner conductive sheet 331 and the outer conductive sheet 332, that is, the upper side of the annular conductive sheet 340 abuts against the lower end of the insulating sphere 320, and the lower side of the annular conductive sheet 340 abuts against the upper end of the connecting portion of the inner conductive sheet 331 and the outer conductive sheet 332. By providing the annular conductive sheet 340, multiple spaced conductive clips 330 can be electrically connected to each other, so that only one second terminal 310 is required to energize all the inner conductive sheets 331.

[0061] Furthermore, if Figure 1 and Figure 2 As shown, the outer conductive sheet 332 is arc-shaped. Figure 4 and Figure 5 As shown, the outer wall surface of the insulating sphere 320 is provided with an arc-shaped groove 322 adapted to the outer conductive sheet 332. Specifically, the thickness of the outer conductive sheet 332 is greater than the depth of the arc-shaped groove 322 of the insulating sphere 320, so that after the outer conductive sheet 332 is embedded in the arc-shaped groove 322, the outer wall surface of the outer conductive sheet 332 will be higher than the outer wall surface of the insulating sphere 320, and then can be engaged with the mounting slot of the electrode mounting seat, thereby preventing the spherical electrode 300 from rotating and shifting in the electrode mounting seat.

[0062] Furthermore, the insulating sphere 320 may be made of rubber material. After the insulating sphere 320 is assembled with the conductive clamp 330 and the annular conductive sheet 340 , high temperature processing may be performed to slightly melt the rubber material and then fuse it with the various components into a whole.

[0063] like Figure 6 and Figure 7 As shown, this embodiment also provides a motor, including the spherical electrode 300 as described above, and also includes a disk electrode 200, a power supply shaft 400 and an electrode mounting seat 100 for connecting a fixed component, and the spherical electrode 300 and the disk electrode 200 are embedded in the electrode mounting seat 100 at intervals. Specifically, Figure 8 and Fig. 9 The schematic diagram of the structure of a conductive device composed of an electrode mounting seat 100, a disk electrode 200 and a spherical electrode 300 is shown. Figures 10 to 12 The schematic diagram of the structure of an electrode mounting seat 100 is shown. The electrode mounting seat 100 is provided with a power supply shaft accommodating chamber (i.e., the third accommodating chamber 140) for connecting the power supply shaft, one end of the power supply shaft accommodating chamber passes through the lower end of the electrode mounting seat 100, and the other end of the power supply shaft accommodating chamber passes through the columnar through hole 321 of the insulating sphere 320 and then passes through the disc-shaped electrode 200.

[0064] like Figures 13 to 15 As shown, the power supply shaft 400 includes a power supply shaft mounting seat 410 for connecting a rotating component and an electrode shaft assembly 420 fixed to the power supply shaft mounting seat 410. The electrode shaft assembly 420 includes an inner electrode shaft 421, an insulating shaft sleeve 423 and an outer electrode shaft sleeve 422 which are coaxially sleeved in sequence. The electrode shaft assembly 420 extends out of the power supply shaft mounting seat 410 and is inserted into the electrode mounting seat 100, and the extension length of the inner electrode shaft 421 is greater than the extension length of the outer electrode shaft sleeve 422. The inner electrode shaft 421 can be rotatably electrically abutted against the disk electrode 200, and the outer electrode shaft sleeve 422 can be rotatably electrically inserted into the columnar through hole 321 of the spherical electrode 300.

[0065] Specifically, the power supply shaft mounting seat 410 can be a hollow shell, and the power supply shaft mounting seat 410 is installed on the rotating component to rotate therewith, and drive the electrode shaft assembly 420 to rotate together. The lower part of the electrode shaft assembly 420 is inserted into the power supply shaft mounting seat 410 to be connected to the equipment to be powered; the upper part of the electrode shaft assembly 420 extends out of the power supply shaft mounting seat 410 to be connected to the conductive device. The inner electrode shaft 421, the insulating shaft sleeve 423 and the outer electrode shaft sleeve 422 are coaxially sleeved in sequence, and are fixed to each other as a whole. Fig.12As shown, the length of the inner electrode shaft 421 is the longest, and the length of the outer electrode shaft sleeve 422 is the shortest. The insulating sleeve 423 is arranged between the inner electrode shaft 421 and the outer electrode shaft sleeve 422 to play an insulating role. The length of the insulating sleeve 423 is less than the length of the inner electrode shaft 421, and it can be equal to or slightly larger than the length of the outer electrode shaft sleeve 422, so that part of the side wall of the inner electrode shaft 421 is exposed while ensuring good insulation effect between the inner electrode shaft 421 and the outer electrode shaft sleeve 422.

[0066] like Figure 6 and Figure 7 As shown, the power supply shaft mounting seat 410 is also fixedly connected to the rotating motor 500 , the inner electrode shaft 421 and the outer electrode shaft sleeve 422 are both electrically connected to the rotating motor 500 , and the output shaft 510 of the rotating motor 500 is away from the electrode mounting seat 100 .

[0067] Furthermore, if Figure 7 , Fig.14 and Fig.15 As shown, the inner electrode shaft 421 and the outer electrode shaft sleeve 422 are both clamped in the power supply shaft mounting seat 410 through corresponding conductive clamping shafts, and the conductive clamping shaft of the inner electrode shaft 421 and the conductive clamping shaft of the outer electrode shaft sleeve 422 are electrically connected to the rotating motor 500.

[0068] Specifically, the length of the inner electrode shaft 421 located in the power supply shaft mounting seat 410 is greater than the length of the outer electrode shaft sleeve 422 located in the power supply shaft mounting seat 410, and the inner electrode shaft 421 is clamped in the power supply shaft mounting seat 410 through the first conductive clamping shaft 431 and the outer electrode shaft sleeve 422 is clamped in the power supply shaft mounting seat 410 through the second conductive clamping shaft 432. The first conductive clamping shaft 431 and the second conductive clamping shaft 432 can be conductive rods extending radially outward from the inner electrode shaft 421. Furthermore, the first conductive clamping shaft 431 and the second conductive clamping shaft 432 can also be arranged in multiple numbers along the circumference of the inner electrode shaft 421. The positions of the first conductive clamping shaft 431 and the second conductive clamping shaft 432 can be parallel and opposite, or can be staggered with each other. A clamping plate 440 corresponding to the conductive clamping shaft is provided in the power supply shaft mounting seat 410, and the conductive clamping shaft is clamped in the clamping groove of the clamping plate 440. The clamping plate 440 can be arranged in the cavity wall of the power supply shaft mounting seat 410.

[0069] By setting up a conductive clamping shaft, not only can the electrode shaft assembly 420 be restricted in the power supply shaft mounting base 410 so that the electrode shaft assembly 420 can rotate synchronously with the power supply shaft mounting base 410, but the conductive clamping shaft can also serve as a wiring terminal. When in use, the first conductive clamping shaft 431 and the second conductive clamping shaft 432 can be respectively connected to the positive and negative poles of the rotating motor 500 with wires to facilitate wiring.

[0070] Furthermore, if Fig.14 and Fig.15As shown, an insulating gasket 450 is also installed between the first conductive clamp shaft 431 and the second conductive clamp shaft 432 to prevent the positive and negative electrodes from contacting each other.

[0071] Furthermore, if Figure 7 As shown, a controller 600 is also installed in the power supply shaft mounting seat 410 , and the conductive clamping shaft of the inner electrode shaft 421 , the conductive clamping shaft of the outer electrode shaft sleeve 422 and the rotating motor 500 are all electrically connected to the controller 600 .

[0072] Specifically, the power supply shaft mounting seat 410 includes a first chamber 411 and a second chamber 412 separated by a partition 413, a first conductive card shaft 431 and a second conductive card shaft 432 are clamped in the first chamber 411, and the controller 600 is installed in the second chamber. A wiring hole 414 is provided at a position corresponding to the card slot on the partition 413. A wire management hole 416 is provided on the side wall of the second chamber 412. The first conductive card shaft 431 and the second conductive card shaft 432 are electrically connected to the controller 600 through the wire 610 passing through the wiring hole 414, and the controller 600 is electrically connected to the rotating motor 500 through the wire 610 passing through the wire management hole 416.

[0073] More specifically, the first chamber 411 and the second chamber 412 can be cylindrical chambers with increasing diameters, and the first chamber 411, the second chamber 412 and the electrode shaft assembly 420 are coaxially arranged. During installation, the bottom of the inner electrode shaft 421 can abut against the partition 413 to ensure axial positioning, and at the same time, the circumferential positioning of the electrode shaft assembly 420 is ensured by the conductive card shaft. The controller 600 can use a microcomputer board, such as an MCU. The controller 600 can rectify, filter, stabilize the current received by the electrode shaft assembly 420, and then supply it to the rotating motor 500 for use. At the same time, it can also control the start and stop, speed or rotation angle of the rotating motor 500.

[0074] Furthermore, the output shaft 510 of the rotary motor 500 is also equipped with an angle sensor and / or a speed sensor (not shown in the figure) electrically connected to the controller 600. The angle sensor can detect the real-time rotation angle of the rotary motor 500, and then the controller 600 controls the rotation of the rotary motor 500 based on the real-time rotation angle and the set rotation angle. Similarly, the speed sensor can detect the real-time speed of the rotary motor 500, and then the controller 600 controls the rotation of the rotary motor 500 based on the real-time speed and the set speed.

[0075] Furthermore, if Figure 7 and Fig.13As shown, the power shaft mounting seat 410 is also provided with a plurality of mounting flanges 415 in the circumferential direction for connecting the rotating component (such as the cross-flow fan 700). The mounting flange 415 may be provided with mounting holes to be connected with the rotating component by bolts. In addition, the mounting flange 415 may also be connected with the rotating component by clamping or welding, etc., which is not limited here.

[0076] An embodiment of the present invention also provides an air conditioner, comprising the motor as described above, and also comprising a casing (not shown in the figure) and a cross-flow fan 700 rotatably connected to the casing, the electrode mounting seat 100 of the motor is fixedly connected to the casing, and the power supply shaft mounting seat 410 of the motor is fixedly connected to the cross-flow fan 700.

[0077] Fig.16 The schematic diagram of the assembly of the motor and the cross-flow fan 700 is shown. When in use, the power supply shaft 400 is installed on the cross-flow fan 700 so that it rotates therewith, and then the power supply shaft 400 is inserted into the electrode mounting seat 100 fixed on the casing of the air conditioner. The electrode mounting seat 100 is embedded with a first electrode and a second electrode as a positive and negative electrode pair. The inner electrode shaft 421 and the outer electrode sleeve 422 of the power supply shaft 400 can respectively maintain rotational contact with the first electrode and the second electrode, and then transmit electrical energy to the rotating motor 500 that rotates together with the cross-flow fan 700, thereby realizing stable power supply from the fixed end to the rotating end, so that the rotating motor 500 can output another rotational motion while rotating with the fan to drive the corresponding components to complete additional rotational movements, thereby enhancing the working stability and reliability of the rotating motor 500.

[0078] In order to better illustrate the installation relationship between the electrode mounting seat 100 and other components in this embodiment, the structure of the electrode mounting seat 100 is described in detail below.

[0079] like Figures 10 to 12As shown, the electrode mounting seat 100 includes an insulating seat body 110, in which a first accommodating cavity 120 for mounting a disk electrode 200, a second accommodating cavity 130 for mounting a spherical electrode 300, and a third accommodating cavity 140 (i.e., a accommodating cavity for the power supply shaft) for mounting a power supply shaft are provided. The first accommodating cavity 120 and the second accommodating cavity 130 are arranged at intervals and are connected through the third accommodating cavity 140. One end of the third accommodating cavity 140 passes through the lower end of the insulating seat body 110, the first accommodating cavity 120 is arranged at the upper end of the third accommodating cavity 140, and the second accommodating cavity 130 is arranged around the outer periphery of the third accommodating cavity 140. The insulating seat body 110 is also provided with a first terminal hole 121 communicating with the first accommodating cavity 120 and a second terminal hole 131 communicating with the second accommodating cavity 130. The first terminal 210 (i.e., the terminal of the disk electrode 200) and the second terminal 310 (i.e., the terminal of the spherical electrode 300) extend out of the electrode mounting base 100 through the first terminal hole 121 and the second terminal hole 131, respectively, to electrically connect to an external power supply device. More specifically, the first terminal hole 121 and the second terminal hole 131 may be located on the same side of the insulating base body 110 so as to be connected to an external power supply device also mounted on the fixed component.

[0080] The insulating seat 110 can be installed on a fixed component, such as the casing of an air conditioner. The insulating seat 110 can be integrally formed using insulating materials such as rubber. The first accommodating cavity 120 can directly use the top space of the third accommodating cavity 140. Since the insulating seat 110 has a certain elasticity, the disc-shaped electrode 200 can be placed from the lower end opening of the third accommodating cavity 140 and finally clamped on the top of the third accommodating cavity 140. Similarly, the spherical electrode 300 can also be placed from the lower end opening of the third accommodating cavity 140 and finally clamped in the second accommodating cavity 130.

[0081] like Figures 10 to 12 As shown, the insulating seat body 110 is composed of a plurality of cylinders with increasing diameters. Furthermore, the insulating seat body 110 includes a first cylinder 111, a second cylinder 112 and a third cylinder 113 with increasing diameters, and an annular groove 150 is formed between the second cylinder 112 and the third cylinder 113 along the radial direction. The annular groove 150 can be matched with the annular protrusion on the fixing component, so that the insulating seat body 110 can be more accurately positioned and installed on the fixing component to prevent axial displacement.

[0082] Furthermore, if Fig.10 and Fig.11As shown, an annular flange 151 is provided on one side of the annular groove 150 close to the second cylinder 112. The annular flange 151 can make the heights of both sides of the annular groove 150 close or equal, thereby avoiding insufficient depth of the annular groove 150 due to the diameter difference between the second cylinder 112 and the third cylinder 113, which is conducive to increasing the stability of positioning.

[0083] Furthermore, if Fig.10 and Fig.11 As shown, the outer wall of the second cylinder 112 is provided with a plurality of first convex ribs 160 protruding outward in the circumferential direction, and the outer wall of the third cylinder 113 is provided with a plurality of second convex ribs 170 protruding outward in the circumferential direction. Specifically, the first convex rib 160 and the second convex rib 170 can be cylindrical convex ribs extending along the axial direction of the second cylinder 112, and accordingly, the first convex rib 160 and the second convex rib 170 can be matched with the recessed portion on the fixing component, thereby preventing the insulating seat body 110 from rotating and shifting. Furthermore, the plurality of first convex ribs 160 and the second convex rib 170 can also be evenly and evenly distributed along the circumferential direction, thereby making the force on the insulating seat body 110 more uniform. At the same time, the first convex rib 160 and the second convex rib 170 can also be staggered with each other.

[0084] Furthermore, if Fig.11 and Fig.12 As shown, the end surface of the third cylinder 113 facing away from the second cylinder 112 is provided with a plurality of grooves 180 which are concave in the axial direction. Specifically, the grooves 180 can be evenly distributed along the circumference of the third cylinder 113. By providing the grooves 180, when the cross-flow fan rotates, a vortex airflow can be formed in the grooves 180, and the vortex airflow collides with the airflow generated by the impeller of the cross-flow fan, changing the direction of the impeller airflow, avoiding the impeller airflow from hitting the volute tongue, generating airflow noise, and improving the sound quality of the air conditioner.

[0085] It can be seen from the above embodiments that the spherical electrode 300, the motor and the air conditioner provided by the present invention, wherein the spherical electrode 300 is clamped on the inner wall surface and the outer wall surface of the insulating sphere 320 by an inner conductive sheet 331 and an outer conductive sheet 332 connected at one end, and the spherical electrode 300 can be clamped in the fixed component by the outer conductive sheet 332, and the outer conductive sheet 332 can be electrically connected to the external power supply equipment, and the inner conductive sheet 331 can maintain rotational contact with the power supply shaft, so that the electric energy of the external fixed power supply equipment can be transmitted to the rotating component. When in use, the spherical electrode 300 and the disk electrode 200 are embedded in the electrode mounting seat 100 together to form a positive and negative electrode pair. The electrode mounting seat 100 can be fixed on the housing of the air conditioner as a fixed component. At the same time, the power supply shaft 400 rotating with the cross-flow fan 700 is inserted into the electrode mounting seat 100, and the inner electrode shaft 421 can be rotatably electrically abutted against the disk electrode 200, and the outer electrode sleeve 422 can be rotatably electrically plugged into the columnar through hole 321 of the spherical electrode 300, thereby transmitting the electric energy of the external power supply device to the rotating motor 500 rotating with the cross-flow fan 700. The spherical electrode 300 and the motor have a simple structure, and realize stable power supply from the fixed end to the rotating end, so that the rotating motor 500 can output another rotational motion while rotating with the motor to drive the corresponding components to complete additional rotational motion, thereby enhancing the stability and reliability of the working of the rotating motor 500.
