Fig. 1 is a schematic structural view of a defrosting assembly and an air conditioner according to an embodiment of the present utility model, as shown in fig. 1, and referring to fig. 2 to 5, the present utility model provides a defrosting assembly including a first driving part 100, a second driving part 200, and a brush stick 300. The first driving part 100 is configured to output a vertical reciprocating motion. The second driving part 200 is connected to the output portion of the first driving part 100 and configured to output a rotational motion rotating around a horizontal axis. The brush bar 300 extends along a horizontal axis and is connected to the output of the second driving part 200.
In this embodiment, the first driving component 100 drives the second driving component 200 and the brush rod 300 to reciprocate in the vertical direction, and at the same time, the second driving component 200 drives the brush rod 300 to rotate, and the bristles or the felt on the rotating brush rod 300 sweep away the impurities such as frost, dust and the like on the coil contacted with the bristles or the felt. After frost is condensed on the outdoor unit 600, the defrosting assembly automatically reciprocates to remove dust, thereby maintaining the heat exchange performance of the air conditioner and ensuring the normal operation of the air conditioner.
In use, the first drive member 100 moves downward while outputting the downward movement, and at the same time, the second drive member 200 outputs the rotational movement, causing the brush bar 300 to rotate. That is, the brush bar 300 moves downward while rotating.
When the first driving part 100 outputs the upward movement, the second driving part 200 moves upward, and at the same time, the second driving part 200 outputs the rotational movement, so that the brush bar 300 rotates. That is, the brush bar 300 moves upward while rotating.
Since the brush bar 300 can move not only in the vertical direction but also rotate around the horizontal axis. In order to ensure the cleaning efficiency, when more frost is required to be cleaned, the moving speed of the brush rod 300 can be reduced, the rotating speed of the brush rod 300 can be increased, and the force of cleaning the frost and ash can be increased; when there is less frost to be cleaned, the moving speed of the brush bar 300 can be increased, and the cleaning speed can be increased.
In some embodiments of the present utility model, the brush rod 300 is cylindrical, a brush structure with cylindrical distribution is fixedly arranged on the periphery of the brush rod 300, and the rotating brush rod 300 drives the brush structure to clean impurities such as frost, dust, etc. on the coil pipe.
In some embodiments of the present utility model, the defrost assembly further comprises a guide member 400, the guide member 400 and the brush bar 300 being movably connected in a vertical guide. Since the first driving part 100 is configured to output the vertical reciprocating motion, in order to prevent the brush bar 300 from being offset during the vertical motion, the guide part 400 is added, and the guide part 400 can limit the brush bar 300 to move in the vertical direction, thereby ensuring that the brush bar 300 can clean the outdoor unit 600 normally.
In some embodiments of the present utility model, the number of brush bars 300 is two, and the two brush bars 300 are angled to each other and are drivingly connected so that the two brush bars 300 rotate in synchronization. Because the two brush bars 300 are angled with each other, the defrosting assembly can clean both sides of the outdoor unit 600 at the same time, so as to adapt to the outdoor unit 600 with two heat exchangers built in or with the coil pipes of the heat exchangers designed as an L shape, and the application range of the defrosting assembly is improved.
In some embodiments of the present utility model, as shown in fig. 2, the first driving part 100 includes a first motor 110, a driving screw 120, and a moving member 130, and the first motor 110 has an upward or downward output end. The drive screw 120 is arranged in the vertical direction, and the drive screw 120 is coaxially connected to the output of the first motor 110. The moving piece 130 is connected with the transmission screw 120 in a spiral transmission manner; the moving member 130 is connected to the second driving part 200.
In this embodiment, the first driving part 100 is designed to be driven by the first motor 110 to rotate the transmission screw 120, so that the moving part 130 moves up and down on the transmission screw 120, and further, the second driving part 200 and the brush rod 300 move up and down. In this way, only the first motor 110 is selected as a motor capable of rotating in the forward and reverse directions, so that the driving screw 120 can rotate in the forward and reverse directions, thereby realizing the reciprocating movement of the second driving part 200 and the brush bar 300.
Further, the second driving part 200 includes a second motor 210, the second motor 210 is connected to the output part of the first driving part 100, and the output end of the second motor 210 faces the horizontal direction and is connected to the brush bar 300. Due to the arrangement of the second motor 210, the second motor 210 can independently control the rotation of the brush rod 300, so that the rotation speed of the brush rod 300 can be controlled according to the amount of frost to be cleaned: when more frost needs to be cleaned, the rotation speed of the brush rod 300 is increased, the force of cleaning the frost and the ash is increased, and the cleaning efficiency is ensured; when less frost needs to be cleaned, the rotation speed of the brush rod 300 is properly reduced, the contact frequency of the brush hair or felt on the brush rod 300 and the cleaned body is reduced, and then the friction is reduced, so that the cleaning speed is improved.
In some embodiments of the present utility model, as shown in fig. 3 and 4, the guide member 400 includes a first guide bar 410, a guide box 420, a second guide bar 430, and a guide block 440. The first guide bar 410 is disposed in a vertical direction. Both sides of the guide box 420 are rotatably connected with the two brush bars 300, respectively; the guide case 420 is provided with a first guide hole 421, and the first guide bar 410 passes through the first guide hole 421. The second guide bar 430 is disposed parallel to and spaced apart from the first guide bar 410. The guide block 440 is rotatably coupled to one end of the other brush bar 300; the guide block 440 is provided with a second guide hole 441, and the second guide rod 430 passes through the second guide hole 441.
In the present embodiment, the first guide bar 410 passes through the first guide hole 421 of the guide box 420 so that the guide box 420 can move up and down on the first guide bar 410; the second guide bar 430 passes through the second guide hole 441 of the guide block 440 such that the guide block 440 can move up and down on the second guide bar 430. In application, one end of one brush rod 300 is connected with the output end of the second motor 210, and the other end is rotatably connected with the guide box 420, and due to the limitation of the first guide rod 410 and the guide box 420, when the transmission screw 120 rotates, the moving part 130 screwed with the transmission screw 120 and the brush rod 300 cannot rotate, so that the brush rod 300 can only drive the guide box 420 to move in the vertical direction, and cleaning of the outdoor unit 600 is realized. Meanwhile, one end of the other brush bar 300 is connected with the guide box 420, and the other end is connected with the guide block 440, and the guide box 420 further drives the brush bar 300 to move up and down. The guide block 440 is disposed to prevent the end of the brush bar 300 away from the guide case 420 from being deviated during the up-and-down movement, thereby ensuring the cleaning of the outdoor unit 600.
Further, as shown in fig. 5, the other end of each brush bar 300 extends into the guide box 420. The other ends of the two brush holders 300 are connected with bevel gears 500, and the two bevel gears 500 are engaged. In this way, on one hand, the bevel gears 500 on the two brush holders 300 are meshed, so that the two brush holders 300 can move synchronously, and cleaning of the outdoor unit 600 is realized; on the other hand, the bevel gear 500 is disposed in the guide case 420, so that it is possible to prevent foreign substances such as moisture, dust, etc. from falling on the bevel gear 500, to rust the bevel gear 500, or to interfere with the movement of the bevel gear 500.
The present utility model also provides an air conditioner including the outdoor unit 600 and the defrosting assembly according to any of the above embodiments, so as to have all the effects of the defrosting assembly. The outdoor unit 600 includes a cabinet and a heat exchanger disposed therein.
In some embodiments of the present utility model, the defrosting assembly is installed between the cabinet and the heat exchanger, so that the brush bar 300 moves up and down closely to the surface of the heat exchanger, and the brush structure goes deep between coils of the heat exchanger, thereby cleaning off impurities such as frost and dust on the coils, avoiding the problem of insufficient heat exchange of the outdoor unit 600, and ensuring the normal operation of the air conditioner.
In use, if frost starts to be condensed on the heat exchanger, the defrosting assembly is started, the first driving part 100 outputs upward or downward movement, the second driving part 200 moves upward or downward, and at the same time, the second driving part 200 outputs rotational movement, so that the brush bar 300 rotates. That is, the brush bar 300 is rotated while being moved upward or downward, and the brush structure of the rotating brush bar 300 cleans the impurities such as frost, dust, etc. on the coil of the heat exchanger.
In some alternative embodiments of the present utility model, the brush bar 300 is attached to the outer wall of the outdoor unit 600 where the heat exchanger is installed. Because the heat exchanger is disposed in the outdoor unit 600 and is closely attached to the inner wall of the outdoor unit 600, the cooling capacity of the heat exchanger is transferred to the side wall of the outdoor unit 600, so that moisture and dust in the ambient air are condensed on the side wall of the outdoor unit 600. The defrosting assembly can clean the side wall of the outdoor unit 600, avoid the problem of insufficient heat exchange amount of the outdoor unit 600, and ensure the normal operation of the air conditioner. Meanwhile, the defrosting assembly is arranged outside the outdoor unit 600, the original main structure and heat exchange function of the outdoor unit 600 are not changed, and the cleaning area of the brush body can be adjusted, so that the side wall of the outdoor unit 600 is cleaned.
In application, if frost starts to be condensed on the outer wall of the outdoor unit 600, the defrosting assembly is started, the first driving part 100 outputs upward or downward movement, the second driving part 200 moves upward or downward, and at the same time, the second driving part 200 outputs rotational movement, so that the brush bar 300 rotates. That is, the brush bar 300 is rotated while being moved upward or downward, and the brush structure of the rotated brush bar 300 cleans foreign matters such as frost, dust, etc. from the outer wall of the outdoor unit 600.
In the prior art, a heating mode is adopted for defrosting, and all the frosted surface of the whole heat exchanger needs to be heated, so that the time is long and the power consumption is high.
