Specific embodiments of the present utility model have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the utility model. Rather, they are merely examples of apparatus and methods consistent with aspects of the utility model as detailed in the accompanying claims. It will be apparent that the described embodiments are some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The air conditioner includes an indoor unit and an outdoor unit. The indoor unit may be used to adjust the indoor temperature. When the air conditioner is used for refrigerating, the outdoor unit can dissipate heat of high-pressure and high-temperature gas exhausted from the indoor unit outdoors, and then the high-pressure and high-temperature gas is cooled and then sent back to the indoor unit so as to cool the indoor environment again, and the circulation is continuously carried out.

An air duct is arranged in the outdoor unit. The outdoor unit may suck external air through the air duct for the purpose of heat exchange with the outside. Dust filtering plates are arranged at the air inlet and the air outlet of the air duct. The dust filtering plate is provided with meshes for preventing impurities from being sucked into the air duct to cause the air duct to be blocked. It can be understood that the normal operation of the air duct heat exchange work directly affects the normal heating or refrigerating effect of the air conditioner, so that the normal operation of the air duct heat exchange work is ensured, and the stability of the air conditioner refrigerating or heating work can be realized.

However, since the outdoor unit is applied to the outdoor environment, on one hand, dust, catkin, dust particles and other impurities are deposited on the meshes of the dust filtering plate due to the action of gravity, which results in the mesh blockage, and on the other hand, the air duct is used for sucking the impurities carried in the air together in the process of sucking outdoor air. Impurities impact on meshes of the dust filtering plate at a certain speed, and particles in the impurities are easy to embed into the meshes, so that the heat exchange effect of the air duct is seriously affected.

Therefore, maintenance personnel are required to disassemble the dust filtering plate regularly and clean impurities so as to reduce the phenomenon that the impurities block the dust filtering plate to influence the heat exchange of the air duct. However, since the air conditioner installation is generally of a certain height, the maintenance personnel operation is time consuming and laborious and presents a safety hazard.

Based on the problems, the applicant provides a dust filter plate self-cleaning device. The dust filter plate self-cleaning device of the present utility model includes a guide rail 110, a driving assembly 120, and a cleaning assembly 130. The driving assembly 120 can drive the sliding block 124 to slide on the guide rail 110 to drive the cleaning brush 131 to move on the dust filtering plate 200, so as to clean impurities on the dust filtering plate 200. Therefore, the self-cleaning device for the dust filter plate can realize self-cleaning of the dust filter plate 200, does not need maintenance personnel to clean the dust filter plate 200 after the air conditioner is disassembled, and is beneficial to saving manpower and reducing labor cost.

The self-cleaning device of the dust filtering plate can be applied to the technical field of air conditioners, can also be used for self-cleaning impurities such as dust on parts in other fields, and is not limited in the utility model.

The dust filter panel self-cleaning device 100 provided by the present utility model is described below with reference to the accompanying drawings in connection with specific embodiments.

Fig. 1 is a schematic view of a self-cleaning device 100 for dust filter plate according to an embodiment of the present utility model, which moves to a position in the middle of a guide rail 110. Fig. 2 is a schematic view of a self-cleaning apparatus 100 for dust filter plate according to an embodiment of the present utility model, which moves to a first end 110a of a guide rail 110. Fig. 3 is a schematic view of a structure of the self-cleaning device 100 for dust filter plate according to an embodiment of the present utility model moving to the second end 110b of the guide rail 110, that is, fig. 3 is a position of the self-cleaning device 100 for dust filter plate in an initial state.

Referring to fig. 1 to 5, a dust filter plate self-cleaning apparatus 100 according to an embodiment of the present utility model includes a guide rail 110, a driving assembly 120, and a cleaning assembly 130.

The guide rail 110 is provided on the cabinet of the external air conditioner and faces the dust filtering plate 200. The guide rail 110 extends in the direction X of the first side of the dust filter plate 200.

The driving assembly 120 includes a driving motor 121, a first traction member 122, a second traction member 123, and a slider 124. The driving motor 121 and the second traction member 123 may be disposed at both ends of the guide rail 110, respectively, in the direction X of the first side. One end of the slider 124 is connected to the first traction member 122, and the other end is connected to the second traction member 123. The other end of the first traction member 122 is connected to a driving motor 121.

The cleaning assembly 130 is disposed on the slider 124. The cleaning assembly 130 includes a cleaning brush 131. The slider 124 slides along the guide rail 110 to move the cleaning brush 131. I.e. the slider 124 can slide in the direction X of the first side.

Referring to fig. 1 to 3, the driving motor 121 may drive the slider 124 to approach in the direction of the driving motor 121 through the first traction member 122. The second traction member 123 can drive the slider 124 to move away from the drive motor 121. The first traction member 122 and the second traction member 123 can drive the sliding block 124 to slide along the guide rail 110. Since the cleaning brush 131 is connected with the sliding block 124, the cleaning brush 131 can be driven to clean on the dust filtering plate 200 through the movement of the sliding block 124, so as to realize self-cleaning of the dust filtering plate 200, thereby reducing the possibility that the mesh on the dust filtering plate 200 is blocked by impurities to influence the heat dissipation effect of the air conditioner.

The self-cleaning device 100 for the dust filtering plate can eliminate the need for maintenance personnel to manually detach and clean the dust filtering plate 200, has the effects of saving time and labor, and is beneficial to improving the intelligent level of an air conditioner.

In some examples, the drive motor 121 may be electrically connected with a control module of the air conditioner. Accordingly, a maintenance person or user may control the operation of the driving motor 121 through the control module to clean the dust filter plate 200.

In some implementations, referring to fig. 4 and 5, the cleaning assembly 130 of embodiments of the present utility model includes a cantilever 132. The suspension 132 is disposed on the slider 124. The cleaning brush 131 is disposed at a side of the cantilever 132 facing the dust filtering plate 200.

When the sliding block 124 slides on the guide rail 110 along the first side direction X, the cantilever 132 drives the cleaning brush 131 to sweep over the dust filtering plate 200, so as to clean impurities on the dust filtering plate 200.

In some examples, the motion profile of the cleaning brush 131 may cover an area of the dust filter plate 200 having mesh holes to sufficiently remove impurities from the mesh holes.

In some implementations, referring to FIG. 4, the suspension 132 of an embodiment of the present utility model is disposed on the side of the slider 124 facing the dust filter plate 200. The cantilever 132 extends in the direction Y of the second side of the dust filter plate 200. The cleaning brush 131 is disposed at a side of the cantilever 132 facing the dust filtering plate 200.

In some examples, the cleaning brush 131 may be disposed over the surface of the cantilever 132 facing the dust filter plate 200, so that impurities on the dust filter plate 200 may be more effectively cleaned by the cantilever 132 during the movement of the slider 124.

In some examples, the dust filter plate 200 may be an elongated plate-like structure. The first and second sides of the dust filter plate 200 may be perpendicular to each other.

In some examples, one end of the cantilever 132 may be coupled to the slider 124 and the other end may be suspended along the direction Y of the second side. Alternatively, the slider 124 may be located between two ends of the suspension 132, with both ends of the suspension 132 in suspension. The present embodiment is not limited thereto.

In some examples, the first side of the dust filter panel 200 may be a long side. The second side may be a short side. Since at least one end of the cantilever 132 is in a floating state, the length of the cantilever 132 is not preferably set longer to reduce the possibility that the cantilever 132 is unstable during movement due to the excessive length of the cantilever 132. In addition, the length of the cantilever 132 is smaller than the distance of the cantilever 132 moving along the direction X of the first side, so that the weight of the cantilever 132 and the cleaning brush 131 can be reduced, and the gravity born by the slider 124 in the running process can be reduced, which is beneficial to improving the stability of the cantilever 132 in the sliding process.

In some implementations, referring to fig. 5, the cantilever 132 of an embodiment of the present utility model includes a first arm 1321 and a second arm 1322. The first arm 1321 and the second arm 1322 may be located at two sides of the slider 124, respectively, along the direction Y of the second side of the dust filter board 200. The surfaces of the first arm 1321 and the second arm 1322 facing the dust filter plate 200 are each provided with a cleaning brush 131.

In some examples, the movement of the cleaning brush 131 on the first arm 1321 and the cleaning brush 131 on the second arm 1322 along the slide rail may meet the cleaning requirements of the dust filter plate 200, and thus the surface of the slider 124 facing the dust filter plate 200 may not be provided with the cleaning brush 131, so as to reduce the weight of the cleaning assembly 130, which is beneficial to improve the flexibility and stability of the slider 124 during sliding.

In some implementations, referring to fig. 1-3, the rail 110 of embodiments of the present utility model may be located in a middle region of the dust filter plate 200 along the direction Y of the second side. The first arm 1321 and the second arm 1322 may be the same length.

In some examples, the sum of the masses of the cleaning brush 131 on the first arm 1321 and the first arm 1321 is the same as the sum of the masses of the cleaning brush 131 on the second arm 1322 and the second arm 1322, and thus, along the direction Y of the second side, both sides of the slider 124 may be uniformly stressed so that the cleaning brush 131 may be more stable during movement.

It will be appreciated that when the forces on the two sides of the slider 124 are uneven, the cleaning brush 131 on one side is likely to contact the dust filter 200 in a transitional manner, so that a large friction force is generated between the cleaning brush 131 and the dust filter 200, the cleaning brush 131 is prevented from moving, and the cleaning brush 131 on the other side is not fully contacted with the dust filter 200, so that the cleaning effect of the dust filter 200 is likely to be affected. The embodiment of the utility model can effectively solve the problems.

In some implementations, referring to fig. 1-3, the slider 124 of an embodiment of the present utility model is provided with a through hole. The guide rail 110 is disposed through the through hole. In the thickness direction Z of the dust filter plate 200, a gap is provided between the slider 124 and the dust filter plate 200.

The through hole penetrates in the direction X of the first side, and thus the slider 124 can slide in the direction of the guide rail 110 when being sleeved outside the guide rail 110 through the through hole. Having a gap between the slider 124 and the dust filter plate 200 may reduce contact between the slider 124 and the dust filter plate 200, and friction between the slider 124 and the dust filter plate 200 may result in a possibility of the movement of the slider 124 being blocked, which may be beneficial to improving flexibility of the movement of the slider 124.

In some implementations, referring to fig. 1-3, the drive assembly 120 may further include a drive shaft 125 and a pulley 126. The drive shaft 125 is connected to the drive motor 121. The driving motor 121 may drive the driving shaft 125 to rotate. Pulley 126 is provided on drive shaft 125. Rotation of the drive shaft 125 may drive the pulley 126 to rotate synchronously.

Wherein, the driving shaft 125 rotates forward to tighten the first traction member 122 to drive the sliding block 124 to slide towards the driving motor 121. Reversing the drive shaft 125 releases the first traction member 122. The second traction member 123 can drive the slider 124 to slide away from the driving motor 121.

Therefore, the first traction member 122 and the second traction member 123 can circularly act on the sliding block 124, that is, the driving motor 121 can circularly drive the driving shaft 125 to rotate forward and reversely, so that the sliding block 124 can reciprocally act along the guide rail 110, and the cantilever 132 can drive the cleaning brush 131 to repeatedly act on the dust filtering plate 200, so as to remove impurities on the dust filtering plate 200.

It can be appreciated that the reciprocating movement of the cleaning brush 131 can more effectively remove the foreign matters on the dust filtering plate 200, which is advantageous to improve the cleaning efficiency and the heat exchanging effect of the air conditioner.

In some implementations, the first traction member 122 of embodiments of the present utility model may be a flexible cord. The second traction member 123 may be an elastic member.

The pulley 126 may tighten the first traction member 122 when the driving motor 121 drives the driving shaft 125 to rotate in a forward direction. The first traction member 122 can draw the sliding block 124 to slide towards the driving motor 121, and drive the cleaning brush 131 to clean the dust filtering plate 200 towards the driving motor 121 through the cantilever 132. When the first traction member 122 pulls the slider 124 to slide in the direction of the driving motor 121, the second traction member 123 is elastically deformed. When the cleaning brush 131 moves to the driving motor 121, the driving motor 121 may drive the driving shaft 125 to reverse to release the first traction member 122. At this time, the slider 124 is no longer subject to the attractive force of the first traction member 122, and thus the second traction member 123 can release the elastic potential energy to slide in a direction away from the driving motor 121. Along with the reverse rotation of the driving motor 121 and the gradual release of the first traction member 122, the second traction member 123 can gradually draw the sliding block 124 and drive the cleaning brush 131 to clean the dust filtering plate 200 in a direction far away from the driving motor 121 through the cantilever 132, and one reciprocating cleaning work is completed until the second traction member 123 is restored to a free state. The driving motor 121 may then continue to circulate in the forward and reverse directions so that the cleaning brush 131 may reciprocally sweep the dust filter plate 200.

In some examples, the cleaning brush 131 may reciprocate a plurality of times to achieve one cleaning operation of the dust filter plate 200.

In some examples, the flexible rope may be a steel wire rope. The elastic member may be a spring. When the first traction member 122 pulls the slider 124 in the direction of the driving motor 121, the spring is stretched to deform. When the first traction member 122 releases the slider 124, the slider 124 is no longer acted by the first traction member 122, and the spring can recover the elastic deformation to drive the slider 124 to move away from the driving motor 121.

In some implementations, referring to fig. 3, the end of the guide rail 110 connected to the driving motor 121 is a first end 110a. The end of the guide rail 110 connected to the second traction member 123 is a second end 110b. The cleaning assembly 130 is proximate the second end 110b when the second traction member 123 is in a free state.

In the embodiment of the present utility model, in the initial state and after the cleaning assembly 130 completes one cleaning operation, in other words, when the cleaning assembly 130 is not in the working state, the cleaning assembly may stay close to the second end 110b, so as to reduce the possibility that the mesh on the dust filtering plate 200 is blocked by the cleaning assembly 130, and the airflow circulation and heat exchange are affected.

In some implementations, the rail 110 is removably coupled to the chassis.

The first end 110a and the second end 110b of the guide rail 110 may be detachably connected to the casing of the air conditioner external unit through a locking member, so that maintenance personnel may conveniently install the dust filtering plate self-cleaning device 100 of the embodiment of the present utility model in the air conditioner external unit, thereby realizing self-cleaning of the dust filtering plate 200.
