At least one embodiment of the present disclosure provides an air conditioner fan blade dust removal device, method, and air conditioner. The air conditioner fan blade dust removal device includes a dust removal mechanism and a controller. The dust removal mechanism includes a brush assembly and a brush assembly driver. The brush assembly and the brush assembly driver are connected in rotation. The brush assembly driver is configured to drive the brush assembly to rotate and control The device is configured to control the movement of the brush assembly so that the brush assembly is located at the position to be cleaned when dust is removed from the blades; when the brush assembly is located at the position to be cleaned, control the rotation of the blades. Therefore, when dust accumulates on the wind blades, the brush assembly can cooperate with the rotation of the wind blades to effectively remove the dust on the wind blades, and prevent the accumulation of dust from affecting the air supply quality of the air conditioner.

Hereinafter, the air conditioner fan blade dust removal device, method, and air conditioner provided by the embodiments of the present disclosure will be described in detail with reference to the drawings and in conjunction with the embodiments.

Fig. 1 shows an air conditioner provided by at least one embodiment of the present disclosure, and Figs. 2 to 13 show the structure of some components in the air conditioner, such as the structure of a fan blade dust removal device in the air conditioner.

As shown in FIGS. 1 to 13, the air conditioner fan blade dust removal device provided by the embodiment of the present disclosure includes a dust removal mechanism 2 and a controller 8, and the dust removal mechanism 2 includes a brush assembly and a brush assembly driver 23. As shown in FIG. 8, the brush assembly and the brush assembly driver 23 are rotatably connected, and the brush assembly driver 23 is configured to drive the brush assembly to rotate. The controller 8 is configured to control the brush assembly driver 23 to drive the brush assembly to move when dust is removed from the blades, so that the brush assembly is located at the position to be cleaned; when the brush assembly is located at the position to be cleaned, control the rotation of the fan blade 1.

For example, in some embodiments, as shown in Figure 1, the air conditioner fan blade dust removal device includes a first mounting seat 3 and a second mounting seat 4. In Figure 1, the first mounting seat 3 is located on the second mounting seat 4. Above. The first mounting base 3 and the second mounting base 4 are used for the installation of the dust removal mechanism 2, for example, the dust removal mechanism 2 is installed between the first mounting base 3 and the second mounting base 4.

For example, in some examples, the first mounting seat 3 and the second mounting seat 4 are also used for the installation of the fan blade 1 of the air conditioner. For example, the wind blade 1 is also installed between the first mounting seat 3 and the second mounting seat 4. As a result, the first mounting seat 3 and the second mounting seat 4 are used to install the fan blade 1 and the dust removal mechanism 2 at the same time, which is beneficial to the integration of the components of the air conditioner.

For example, in some embodiments, as shown in FIG. 8, a rotating shaft 24 is provided on the brush assembly, and a rotating shaft connecting hole 27 is provided on the rotating shaft 24. The brush assembly driver 23 is, for example, a motor, and the rotating shaft of the motor is connected with the rotating shaft connecting hole 27. Mating fit. When the fan blade dust is removed, the controller 8 controls the motor to drive the brush assembly to move so that the brush assembly is located at the position to be cleaned; when the brush assembly is at the position to be cleaned, the controller 8 controls the rotation of the fan blade 1 to make the brush assembly Relative movement is formed with the blade 1. For example, the position to be cleaned is such that at least the bristles 21 are in contact with the blade 1, that is, when the blade 1 is in operation, a certain friction is formed between the bristles 21 and the blade 1. For example, a part of the bristles 21 is inserted along the circumferential direction of the blade 1. Between the provided air guide strips, since the bristles 21 themselves are flexible materials, the brush assembly will not affect the operation of the wind blade 1.

Thus, when dust accumulates on the fan blade 1, the dust on the fan blade 1 can be cleaned by the brush assembly in cooperation with the rotation of the fan blade 1, so as to prevent the accumulation of dust from affecting the air supply quality. In addition, through the brush The arrangement of the components can more thoroughly remove the dust on the fan blade 1, making the dust removal more effective.

For example, in some embodiments, as shown in FIG. 11, the brush assembly includes bristles 21 and a connecting plate 28. For example, the bristles 21 are fixedly connected to the connecting plate 28, that is, the bristles 21 are fixedly connected to the connecting plate 28.

It should be noted that the bristles 21 in the figure are shown as a block structure, which is a simplified structure of the bristles 21. For example, the bristles 21 are formed by combining several hair-like structures. The bristles 21 can be detachably connected to the connecting plate 28. For example, the bristles 21 can be mounted on the connecting plate 28 by clamps; the connecting plate can also be provided with connecting holes, and the tufted bristles 21 can be inserted and matched with the connecting holes. The bristles 21 can also be bonded to the connecting plate 28. The advantage of this arrangement is that the bristles 21 are arranged on the connecting plate 28. When the bristles are damaged or deformed, the bristles 21 are not replaced separately, and the connecting plate 28 and the whole are replaced, avoiding unnecessary trouble.

For example, in some embodiments, as shown in FIGS. 8 to 10, the brush assembly may further include a mounting base 22. For example, the mounting base 22 is provided with a slot 29, and the connecting plate 28 is slidably connected to the slot 29, for example , The connecting plate 28 can be detachably mounted on the mounting seat 22 by sliding in the slot 29.

For example, as shown in FIG. 10, the mounting base 22 is provided with a slot 29, the socket of the slot 29 is located on the right side of the mounting base 22 in FIG. 10, and the connecting plate 28 is inserted into the slot 29 along the socket. For example, a bristle opening is provided on the side of the slot 29, that is, a bristle opening is provided on the lower side in FIG. 10, and the bristle opening is convenient for exposing the bristles. When installing the dust removal assembly, the bristles 21 can be fixed on the connecting plate 28 first, and then the connecting plate 28 can be cut into the slot 29.

Therefore, the connecting plate 28 is plugged and fitted with the mounting base 22 to facilitate the disassembly and assembly of the connecting plate 28. Only by inserting the connecting plate 28 from the slot 29 to install the bristles 21, the connecting plate 28 is inserted from the socket. If the slot 29 slides out, the connecting plate 28 can be replaced.

For example, in some embodiments, as shown in FIGS. 12 and 13, a limiting structure 20 is provided on the inner side of the slot 29. When the connecting plate 28 is inserted into the slot 29, the limiting structure 20 is used to restrict the connecting plate 28 along the insertion direction. , The relative position of the connecting plate 28 and the mounting base 22 is fixed.

For example, as shown in FIG. 13, the limiting structure 20 can be arranged at the bottom of the slot 29, that is, the limiting structure 20 is arranged on the upper side of the slot 29 in FIG. 13. For example, the limiting structure 20 is provided with a guiding inclined surface, so that when the connecting plate 28 is inserted into the slot 29, it slides into the slot 29 along the guiding inclined surface. When the connecting plate 28 is slid into the slot 29, the limiting structure 20 is connected to The board 28 is restricted to prevent the connecting board 28 from sliding out of the slot 29.

For example, in some embodiments, as shown in FIGS. 1 and 2, two rotating shafts 24 are provided at both ends of the mounting base 22 of the brush assembly, and the first mounting base 3 and the second mounting base 4 are respectively provided with and The rotating shaft 24 corresponds to a rotating shaft connecting hole (not shown in the figure), and the rotating shaft 24 is rotatably connected with the rotating shaft connecting hole to install the brush assembly on the first mounting seat 3 and the second mounting seat 4.

It should be noted that the two ends of the mounting base 22 are provided with two rotating shafts 24, which means that the two ends of the mounting base 22 are respectively provided with a rotating shaft 24, and the positions of the two rotating shafts 24 are the same as those of the first mounting base 3 and the The position of the connecting hole of the rotating shaft on the second mounting seat 4 corresponds to that of the rotating shaft 24 and the rotating shaft connecting hole, so as to ensure that the brush assembly is in the position to be cleaned, so that the bristles 21 and the blade 1 are in contact. When the blade 1 rotates, Through the relative movement of the bristles 21, the dust on the wind blade 1 is cleaned. For example, in other embodiments, the two rotating shafts may also be provided on the first mounting seat 3 and the second mounting seat 4, respectively, and the two ends of the mounting seat 22 are respectively provided with rotating shaft connecting holes corresponding to the rotating shafts. The installation of the brush assembly on the first mounting seat 3 and the second mounting seat 4 is realized.

Thus, the mounting base 22 is connected to the first mounting base 3 and the second mounting base 4 by a rotating shaft. When the fan blade 1 needs to be cleaned, the brush assembly is rotated so that the brush assembly is located at the position to be cleaned. When the cleaning is completed or does not need to be cleaned, the contact between the brush assembly and the fan blade 1 can be avoided, and the brush assembly can be rotated to reset the brush assembly to the initial position.

For example, in some embodiments, as shown in FIGS. 1 and 3, the air-conditioner fan blade dust removal device further includes a water receiver 9, and the water receiver pan 9 is arranged on the side of the second mounting seat 4 away from the first mounting seat 3. . In FIG. 1, the second mounting seat 4 is arranged above the water receiving tray 9. For example, the second mounting seat 4 is provided with a through hole 7 which is used to allow the dust falling off the fan blade 1 to pass through, that is, the dust falling off the fan blade 1 can enter the drain pan 9 through the through hole 7.

In order to ensure that dust can directly enter the drain pan after falling from the fan blade 1, a through hole 7 is provided on the second mounting seat 4, and the dust falls from the fan blade 1 through the through hole 7 and falls into the drain pan. For example, there may be multiple through holes 7 to speed up the speed of dust entering the drain pan. The embodiment of the present disclosure does not limit the number of through holes 7. In addition, it should be noted that the dust accumulated on the fan blade 1 is usually not enough to block the water receiving tray 9, that is, the capacity of the water receiving tray 9 can be set to be large enough to make the dust accumulated on the fan blade 1 not enough. So that the drain pan 9 is blocked.

For example, in some embodiments, as shown in Figure 8, the second mounting base 4 is provided with a screw hole (not shown in the figure), the brush assembly driver 23 is provided with a lug 25, and the lug 25 is provided with The mounting hole 26 is matched with the screw hole 26, so that the brush assembly driver 23 is mounted on the second mounting base 4 by screws. Or, in other embodiments, it is also possible that a lug is provided on the second mounting base 4, and a mounting hole 26 is provided on the lug, and a screw hole, a screw hole and a mounting hole 26 are provided on the brush assembly driver 23. Match, so that the brush assembly driver 23 is mounted on the second mounting base 4 by screws.

In the above-mentioned embodiment, the brush assembly driver 23 is fixedly installed on the second mounting base 4 by screw fastening. However, the embodiment of the present disclosure has a connection mode for the second mounting base 4 and the second mounting base 4 There is no specific limitation. For example, in other embodiments, the brush assembly driver 23 can also be fixedly installed on the second mounting base 4 through other fixing methods similar to snap-fitting. For example, in some examples, the brush assembly driver 23 uses a driving device such as a motor. There may be one or more lugs 25, and each lug 25 is provided with a corresponding mounting hole 26, and the number of screw holes corresponds to the number of mounting holes 26. The screw fastening method can facilitate the disassembly and maintenance of the motor.

For example, in some embodiments, as shown in FIGS. 4 and 5, the first mounting base 3 and/or the second mounting base 4 is provided with a first limiting structure 5, which is suitable for limiting the initial position of the brush assembly.

For example, the first limiting structure 5 is a limiting protrusion, and when the brush assembly rotates, the first limiting structure 5 is used to stop the mounting seat 22. That is to say, the position defined by the first limiting structure 5 is the initial position of the brush assembly. When the brush assembly is reset after cleaning the dust, the brush assembly rotates back to the initial position. At this time, the first limiting structure 5 can It acts as a stop to prevent the brush assembly from rotating too large and interfere with the air conditioner. At the same time, it also limits the initial position of the brush assembly. It should be noted that the first limiting structure 5 may only be provided on the first mounting base 3 or the second mounting base 4, or may be provided with the first mounting base 3 and the second mounting base 4 Limit structure 5.

For example, in some embodiments, as shown in FIGS. 6 and 7, the first mounting seat 3 and/or the second mounting seat 4 is provided with a second limiting structure 6 for limiting the position to be cleaned of the brush assembly .

For example, the second limiting structure 6 is a limiting protrusion. When the brush assembly rotates, the second limiting structure 6 is adapted to stop the mounting seat 22. That is to say, the position defined by the second limiting structure 6 is the position to be cleaned of the brush assembly. When the wind blade is cleaned, the brush assembly rotates to the position to be cleaned. At this time, the second limiting structure 6 can be used for cleaning. To stop, prevent the brush assembly from rotating too large and interfere with the air conditioner, and at the same time, it also ensures the best cleaning position. It should be noted that the second limiting structure 6 may only be provided on the first mounting base 3 or the second mounting base 4, or may be provided with the second mounting base 3 and the second mounting base 4 Limit structure 6.

For example, as shown in FIG. 1, an air conditioner provided by an embodiment of the present disclosure includes any one of the above-mentioned air conditioner fan blade dust removal devices. The air conditioner provided by the embodiment of the present disclosure has the same beneficial effects as the above-mentioned fan blade dust removal device, which will not be repeated here.

The embodiment of the present disclosure also provides a method for removing dust from the air blade of an air conditioner. The indoor unit of the air conditioner includes a brush assembly, for example, the brush assembly provided in the embodiment of the present disclosure. For example, the air-conditioner fan blade dust removal method is used in the air-conditioner fan blade dust removal device provided by the embodiment of the present disclosure. As shown in Fig. 14, the method for removing dust from wind blades includes steps S1-step S3.

Step S1: Obtain the dust removal instruction of the air conditioner.

Step S2: Control the brush assembly to move to the position to be cleaned.

Step S3: Control the rotation of the wind blades to cause friction between the brush assembly and the wind blades.

In real life, static electricity is generated by the rotation of the fan blade 1 in the indoor unit and the air friction, which causes dust to accumulate on the fan blades. When the air conditioner runs for a certain period of time, the dust needs to be cleaned in time to increase the air supply of the air conditioner. quality. In this embodiment, the dust removal mode can be set in the air conditioner, and the controller can control the air conditioner to enter the dust removal mode. It can be done manually or automatically through the air conditioner. When a certain condition is reached, it will be automatically performed when the air conditioner is idle. Dust removal.

For example, when the dust removal instruction is obtained, the brush assembly is first driven to move to the position to be cleaned, and then the fan blades are controlled to rotate, so as to form a relative movement between the brush assembly and the fan blade 1. The friction between them cleans the dust on the wind blade 1. The advantage of this setting is that when dust accumulates on the fan blade 1, the dust on the fan blade 1 can be brushed away in time through the dust removal mode to avoid affecting the air supply quality. The setting of the brush assembly can be used to The dust on the fan blade 1 is brushed more thoroughly to make the dust removal more effective.

For example, in step S2, the brush assembly is at the initial position at the beginning, and the initial position keeps the brush assembly away from the blade 1 to avoid friction between the blade 1 and the brush assembly during operation. After the dust removal instruction is obtained , The air conditioner controls the operation of the brush assembly driver 23 and drives the brush assembly to the position to be cleaned. For example, the position to be cleaned is such that at least the bristles 21 are in contact with the wind blade 1. It can also be said that when the wind blade 1 is in operation, a certain friction is formed between the bristles 21 and the wind blade 1. For example, some of the bristles 21 are inserted along the wind. Between the air guide strips arranged in the circumferential direction of the blade 1, because the bristles 21 themselves are flexible materials, the brush assembly will not affect the operation of the air blade 1.

For example, in step S3, controlling the rotation of the blade 1 includes: controlling the rotation of the blade 1 in reverse. Because the air guide strip of the wind blade 1 is arranged obliquely and presents a certain angle with the circumferential direction of the wind blade 1, the dust is usually concentrated on the side pointed by the reverse rotation of the wind blade 1. When the wind blade 1 rotates forward, the wind is guided. It can be used in the cooling mode or heating mode of the air conditioner; and when the fan 1 is reversed (reverse and forward rotation are opposite), the airflow generated by the fan 1 can be reduced, and the airflow caused by the dust can be avoided. Dust is blown into the room; on the other hand, the fan blade 1 is reversed to clean up the dust-collected locations. Of course, it is also possible to control the forward rotation of the fan blade 1, or alternate forward and reverse rotations of the fan blade 1. By alternating the forward rotation and the reverse rotation of the fan blade 1, the fan blade 1 is shaken to facilitate dust cleaning.

For example, during the process of forward rotation or reverse rotation of the fan blade 1, the rotation speed of the fan blade 1 is controlled to fluctuate within a set speed interval. That is to say, the rotation speed of the wind blade 1 is changed, not constant, and the rotation speed of the wind blade 1 changes within the set rotation speed range, and the change may be regular or irregular. For example, when the rotation speed of the fan blade 1 increases to 100 r/min, the rotation speed of the fan blade 1 starts to change in the range of [100, 150] r/min. Of course, the rate can also be other values. The advantage of this arrangement is that the vibration of the wind blade 1 is formed by the change of the rotation speed of the wind blade 1, which can improve the cleaning efficiency of dust.

For example, in this embodiment, the dust removal method for air conditioner blades may further include: when the blade 1 rotates for a first preset time, controlling the air conditioner to perform a condensation operation, so that the heat exchanger in the air conditioner room generates condensed water .

Therefore, within the first preset time, the brush assembly cleans the dust on the fan blade 1; when the dust is brushed away from the fan blade 1, it will collect in the water tray. At this time, the dust in the water tray needs to be docked. Clean up the dust. Therefore, when the fan blade 1 operates for the first preset time, the condensation operation starts. At this time, through condensation control, the condensed water in the air can be collected on the surface of the heat exchanger and flow down from the heat exchanger to Drain tray to take away the dust in the tray. For example, in other examples, the surface of the heat exchanger can also be frosted, and then subjected to a defrosting treatment to make the surface of the heat exchanger form condensed water.

For example, in some examples, the condensation operation includes: controlling the air conditioner to operate in a cooling mode; when the air conditioner meets a preset condition, controlling the air conditioner to enter a heating mode, so that the heat exchanger generates condensed water.

It should be noted that through the cooling mode, the temperature of the indoor unit heat exchanger can be rapidly reduced, causing condensation or even frost on the surface of the heat exchanger, and then defrosting through the heating mode. Therefore, through cooling and reheating, a certain amount of condensed water will accumulate on the heat exchanger of the air conditioner. When a certain amount of condensed water passes through, it will flow into the drain pan, and the dust in the drain pan will be taken away by the condensed water. .

For example, in some examples, the foregoing preset condition is: the air conditioner operates in the cooling mode for the second preset time. That is, when the air conditioner operates in the cooling mode for the second preset time, the air conditioner is controlled to enter the heating mode. The second preset time is set according to the time required for actual frost formation or condensation water generation. Through time control, the hardware cost of the air conditioner can be reduced, and the control can be more precise.

For example, in some other examples, the air-conditioner fan blade dust removal method further includes: during the condensation operation, when the air-conditioner is running in the cooling mode, obtaining the temperature of the heat exchange tube of the heat exchanger; The set condition is: when the temperature of the heat exchange tube of the heat exchanger reaches the preset temperature, the air conditioner continues to operate for the third preset time.

That is to say, when the air conditioner is cooling, the temperature of the heat exchange tube of the indoor unit heat exchanger is monitored, so that the temperature of the heat exchange tube ensures that frost or condensed water is formed on the heat exchanger. When the temperature of the heat exchanger reaches At the frosting temperature, the air conditioner is controlled to continue to operate in the cooling mode for a third preset time, and then start to operate in the heating mode to defrost, so that the frost is liquefied to form condensed water. Therefore, by monitoring the temperature of the heat exchange tubes of the heat exchanger, it is ensured that frost is formed on the heat exchanger, thereby ensuring the generation of sufficient condensate water. On the other hand, when the temperature of the heat exchange tube of the heat exchanger reaches the preset temperature, it continues to operate for a period of time, which can ensure that the heat exchanger forms frost or condensation.

For example, in some embodiments, when the air conditioner starts to operate in the cooling mode, the control fan 1 is stopped. In other words, the fan blade 1 is in contact with the brush assembly during operation to form a relative movement to clean the dust on the fan blade 1. When the fan blade 1 runs for the first preset time, the fan blade 1 stops rotating and the air conditioner Turn on the cooling mode. The advantage of this arrangement is that stopping the operation of the fan during cooling can reduce the heat dissipation of the heat exchanger and change the speed at which the temperature of the heat exchanger decreases.

For example, after the rotation of the fan blade 1 continues for the first preset time, the operation of the brush assembly is controlled to reset the brush assembly. Here, after the rotation of the blades continues for the first preset time, it may refer to when the rotation of the blades continues for the first preset time, or it may mean that the rotation of the blades continues for the first preset time before the dust removal mode ends, and the brush The component reset can avoid the interference of the brush to the operation of the fan 1 during normal operation.

For example, in some embodiments, the method for removing dust from the fan blades of an air conditioner may further include the end of dust removal when the heating mode is operated for a fourth preset time. In the fourth preset time, the heating mode is turned on, so that the frost on the heat exchanger is liquefied to form condensed water. Through time control, the hardware cost of the air conditioner can be reduced, and the control can be more precise. It should be noted that when the heating mode is running, the temperature of the heat exchange tube of the heat exchanger can also be obtained. When the temperature of the heat exchange tube reaches the set temperature, the heating ends, thereby ensuring complete defrosting.

In the embodiment of the present disclosure, the first predetermined time, the second predetermined time, the third predetermined time, and the fourth predetermined time can be set according to actual application conditions, for example, set to 15 seconds, 30 seconds, 1 minute, and 2 minutes. Or 5 minutes, etc., which are not limited in the embodiment of the present disclosure.
