DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The inventors have discovered that dishwashers use brushes or nozzles of fixed height to clean bowls, plates and other utensils. Since utensils come in different shapes and sizes, it is difficult for a brush or nozzle of fixed height to clean utensils of different shapes and may not be able to achieve a thorough cleaning effect, resulting in the presence of residues or stains.

In addition, the inventors have also found that using a single brush to act on a vessel is not only difficult to adapt to the shapes and sizes of different vessels, but also has a limited cleaning area and poor cleaning efficiency. Using multiple brushes to act on the same vessel at the same time can effectively increase the cleaning area. However, most vessels have arc surfaces, corners and other parts that are difficult to clean. It is necessary to design the installation method of multiple brushes to effectively achieve the purpose of taking into account both cleaning effect and cleaning efficiency. Based on this, the embodiment of the present application provides a cleaning brush structure and a dishwasher. The cleaning brush structure has multiple retractable brushes that can adapt to a variety of different specifications of vessels, with good cleaning effect and cleaning efficiency.

As shown in FIG. 1 and FIG. 2 , a cleaning brush structure 10 is provided in an embodiment of the present application. The cleaning brush structure 10 is used in a dishwasher and includes a plurality of brush units 100 and a driving assembly 200 .

The multiple brush units 100 include a telescopic assembly 110 and a brush 120. One end of the brush 120 is used to contact the vessel 20, and the other end of the brush 120 is connected to the telescopic assembly 110. The parts of the brushes 120 of the multiple brush units 100 that are used to contact the vessel 20 are arranged toward the same side, that is, they are all arranged toward the side away from the telescopic assembly 110, so that the brush 120 contacts the vessel 20, and the multiple brushes 120 of the multiple brush units 100 can contact the vessel 20 together, thereby increasing the cleaning area.

The telescopic assembly 110 is used to drive the brush 120 to move along a preset direction X when the brush 120 contacts the vessel 20. The telescopic assembly 110 can drive the brush 120 to move in a direction close to the vessel 20, or the telescopic assembly 110 can drive the brush 120 to move in a direction away from the vessel 20, so that the brush 120 is in a suitable position to clean the vessel 20, and when the brush 120 is in a suitable cleaning position, the telescopic assembly 110 can also provide a pre-tightening force to prevent the brush 120 from rebounding or unstable fitting when in contact with the vessel 20, thereby improving the stability of the cleaning operation.

The telescopic components 110 of each brush unit 100 can independently drive the corresponding brush 120 to move along the preset direction X, so that when each brush 120 contacts the corresponding part of the vessel 20, each telescopic component 110 can drive the brush 120 to move in the preset direction X, thereby adapting to the shape of the vessel 20. When the brushes 120 of multiple brush units 100 contact the vessel 20 at the same time, the strokes of the brushes 120 of each brush unit 100 in the preset direction X may be equal or unequal, and the strokes of the brushes 120 of each brush unit 100 in the preset direction X depend on the shape of the vessel 20. In addition, based on the containers 20 of different shapes and sizes, the brushes 120 of some or all of the brush units 100 may be in contact with the same container 20. For example, when the size of the container 20 is large, the brushes 120 of all the brush units 100 may be in contact with the same container 20. When the size of the container 20 is small, the brushes 120 of some of the brush units 100 may be selected to be in contact with the same container 20. The above is only an exemplary introduction. The embodiment of the present application does not limit which brush units 100's brushes 120 are in contact with the container 20, and the specific selection can be made according to cleaning needs.

The driving assembly 200 includes a driving member 210 and a transmission member 220 connected to the driving member 210. The driving member 210 is used to drive the transmission member 220 to drive each brush 120 to rotate around a preset direction X. The brush 120 has a first tooth 1201, and the transmission member 220 has a second tooth 2201. The second teeth 2201 of the transmission member 220 cooperate with the first teeth 1201 of the brushes 120 of the plurality of brush units 100, so that when the driving member 210 drives the transmission member 220 to drive each brush 120 to rotate around the preset direction X, the brushes 120 of the plurality of brush units 100 can slide along the preset direction X to adapt to the shape of the vessel 20.

In the embodiment of the present application, the brushes 120 of the multiple brush units 100 cooperate with each other to act on different parts of the vessel 20. The brushes 120 of the multiple brush units 100 can move independently in a preset direction X, and the moving strokes can be different. The brushes 120 of each brush unit 100 can also rotate. Such linkage makes the cleaning brush structure 10 of the present application suitable for cleaning vessels 20 of different shapes and sizes, and can also clean corners, curved surfaces and other parts that are difficult to clean, effectively improving the cleaning effect and cleaning efficiency.

Optionally, the directions in which the telescopic components 110 of the multiple brush units 100 drive the brushes 120 to move can be parallel or at an angle to each other. For example, taking the multiple brush units 100 as an example of being distributed in a circle along a preset central axis, the directions in which the telescopic components 110 of each brush unit 100 drive the brushes 120 to move form an angle with the preset central axis, and the angles are equal, so that the directions in which the telescopic components 110 of two adjacent brush units 100 drive the brushes 120 to move form an angle with each other. Preferably, the directions in which the telescopic components 110 of the multiple brush units 100 drive the brushes 120 to move are parallel, so that the brushes 120 of the multiple brush units 100 can move smoothly and independently, reducing mutual interference during the movement of the multiple brushes 120.

Specifically, the brush 120 includes a brush rod 121 and a flexible member 122. As shown in FIG3 , the brush rod 121 includes a first section 1211 and a second section 1212. The flexible member 122 is disposed at the first section 1211 of the brush rod 121 and is used to contact the vessel 20. The second section 1212 of the brush rod 121 is connected to the telescopic assembly 110. The axial direction of the brush rod 121 is a preset direction X, that is, the direction in which the telescopic assembly 110 of each brush unit 100 drives the brush 120 to move is the axial direction of the brush rod 121. Optionally, the axial directions of the brush rods 121 of the plurality of brush units 100 are parallel, and the brushes 120 of the plurality of brush units 100 move in mutually parallel directions driven by the corresponding telescopic assembly 110 to contact the vessel 20.

It should be noted that the flexible member 122 described in the embodiment of the present application is a structure with a certain supporting strength that can abut against the surface of the vessel 20, and can be deformed when abutting against the surface of the vessel 20. After the external force is removed, the flexible member 122 can restore the deformation, so that the cleaning requirements can be better met. Optionally, the flexible member 122 may include a plurality of soft hairs, and the plurality of flexible members 122 are arranged on the brush rod 121 in a direction that is at an angle to the axial direction of the brush rod 121, and are divergent, so as to more efficiently clean the vessel 20. The material of the soft hair includes but is not limited to artificial fiber, plant fiber, animal hair, silicone, rubber and other materials. Alternatively, the flexible member 122 may also be a porous flexible structure such as sponge and cotton. The above is only an exemplary introduction, and any structure that is flexible and can clean the surface of the vessel is applicable to this application.

As shown in Fig. 3 and Fig. 4, the brush rod 121 also includes an intermediate section 1213 connected between the first section 1211 and the second section 1212. Optionally, the first section 1211, the second section 1212 and the intermediate section 1213 are coaxial. The axial direction of the intermediate section 1213 is the axial direction of the brush rod 121. The intermediate section 1213 has a first tooth 1201, which is a bar tooth. The length of the bar tooth in the axial direction of the brush rod 121 is L. The travel of the brush rod 121 driven by the telescopic assembly 110 to move along the axial direction of the brush rod 121 is S, S<L. In this way, the first tooth 1201 and the second tooth 2201 can slide relative to each other in the axial direction of the brush rod 121 and are not easily separated, so that the brush rod 121 can not only rotate around the axial direction of the brush rod 121 under the drive of the second tooth 2201 of the transmission member 220, but also move smoothly in the axial direction of the brush rod 121.

The number of the first teeth 1201 may be one or more. When the number of the first teeth 1201 is one, when the driving member 210 drives the transmission member 220 to move, the second tooth 2201 of the transmission member 220 moves the first tooth 1201 in a direction perpendicular to the axial direction of the brush rod 121, so as to drive the brush 120 to rotate a certain angle around the preset direction X. When the number of the first teeth 1201 is multiple, the multiple first teeth 1201 are distributed axially around the brush rod 121, and correspondingly, the number of the second teeth 2201 of the transmission member 220 can be set to be multiple, so that the number of the first teeth 1201 meshing with the second teeth 2201 is greater, so that the transmission member 220 drives the brush 120 to rotate around the brush rod 121 axially at a greater angle, which helps to improve the cleaning effect and cleaning efficiency.

Optionally, when multiple brush units 100 are distributed in a circle around a preset central axis, specifically, the moving directions (preset direction X) of the brushes 120 of the multiple brush units 100 can be set at an angle with the preset central axis, and the angles are equal, so that the moving directions of the brushes 120 of the multiple brush units 100 are divergent; or, the moving directions (preset direction X) of the brushes 120 of the multiple brush units 100 are parallel, and the preset central axis is parallel to the moving direction of the brush 120. At this time, the transmission member 220 includes a driving gear 230 and a gear ring (not shown in the figure), the gear ring is sleeved on the outer periphery of the brush 120 of the multiple brush units 100, specifically, the gear ring is sleeved on the outer periphery of the brush rod 121 of the multiple brush units 100, the inner periphery of the gear ring has a plurality of second teeth 2201, the plurality of second teeth 2201 of the gear ring are meshed with the first teeth 1201 of the brush rod 121 of the multiple brush units 100, the outer periphery of the gear ring has a plurality of third teeth meshed with the driving gear 230, the axial direction of the driving gear 230 is parallel to the preset central axis, the driving member 210 is connected to the driving gear 230 to drive the driving gear 230 to rotate around a direction parallel to the preset central axis, the driving gear 230 drives the teeth to rotate around the preset central axis, and then drives the brushes 120 of the multiple brush units 100 to rotate around the axial direction of their brush rods 121, so that the brushes 120 of the multiple brush units 100 are driven to rotate simultaneously by one driving member 210.

Further, the driving member 210 can continuously drive the driving gear 230 to rotate in the same direction, so that the brush 120 of each brush unit 100 continuously rotates in the same direction. Alternatively, the driving member 210 can also drive the driving gear 230 to rotate in one direction in a first time period, so as to drive the brush 120 of each brush unit 100 to rotate in the same direction in the first time period, and then the driving member 210 drives the driving gear 230 to rotate in the opposite direction in a second time period, so as to drive the brush 120 of each brush unit 100 to rotate in the opposite direction in the second time period, so as to drive the brush 120 to rotate back and forth.

Optionally, please refer to Figure 1 again, multiple brush units 100 are distributed in strips, specifically, multiple brush units 100 are arranged side by side along the first direction Y, the moving directions (preset direction X) of the brushes 120 of the multiple brush units 100 are parallel, and the first direction Y is perpendicular to the preset direction X. At this time, the transmission member 220 includes a driving gear 230 and a rack 222. The rack 222 is arranged on the same side of the brushes 120 of the multiple brush units 100 in the second direction. The preset direction X, the first direction Y and the second direction are perpendicular to each other. The rack 222 has a plurality of second teeth 2201 arranged side by side along the first direction Y. The plurality of second teeth 2201 are meshed with the first teeth 1201 of the brushes 120 of the multiple brush units 100. The rack 222 also has a plurality of fourth teeth arranged side by side along the first direction Y. The plurality of fourth teeth are meshed with the driving gear 230. The axial direction of the driving gear 230 is perpendicular to the first direction Y. The driving member 210 is connected to the driving gear 230 to drive the driving gear 230 to rotate in a direction perpendicular to the first direction Y, thereby driving the rack 222 to translate in a direction parallel to the first direction Y, thereby driving the brushes 120 of the multiple brush units 100 to rotate around the axial direction of their brush rods 121.

Among them, the driving member 210 can drive the driving gear 230 to rotate in one direction within a first time period, so as to drive the rack 222 to move a distance in one direction, and then drive the brush 120 of each brush unit 100 to rotate a first angle in the same direction within the first time period. Then, the driving member 210 drives the driving gear 230 to rotate in the opposite direction within a second time period, so as to drive the rack 222 to move a distance in the opposite direction, and then drive the brush 120 of each brush unit 100 to rotate a second angle in the opposite direction within the second time period, so as to drive the brush 120 to rotate reciprocatingly.

The above is only an exemplary introduction to the rotation method of the brush 120. The rotation method of the brush 120 in the embodiment of the present application includes but is not limited to the rotation method shown above, and can be selected according to actual needs. The embodiment of the present application does not limit the type of the driving member 210. Any structure that can drive the driving gear 230 to rotate is applicable to the present application. For example, the driving member 210 can be a driving motor, a stepping motor, etc.

As shown in FIG5 , in addition to cleaning the tableware by friction between the brush 120 and the vessel 20, the embodiment of the present application also provides the brush 120 with an infusion channel 120a, one end of which forms a liquid outlet 120b, and the liquid outlet 120b is used to face the vessel 20 so that the cleaning liquid is transported to the vessel 20 through the liquid outlet 120b, and the cleaning liquid adheres to the surface of the vessel 20 and cleans the surface of the vessel 20 under the drive of the brush 120, and the flowing cleaning liquid can also take away the cleaned dirt, effectively improving the cleaning efficiency and cleaning effect. Optionally, the surface of the first section 1211 of the brush rod 121 is provided with a liquid outlet 120b.

The brush unit 100 further includes a liquid storage tank 300 for buffering cleaning liquid. The liquid storage tank 300 is communicated with the liquid outlet 120b so that the cleaning liquid in the liquid storage tank 300 can flow out from the liquid outlet 120b. Specifically, an infusion opening 120c is formed at the other end of the infusion channel 120a, and the liquid storage tank 300 can be directly connected to the infusion opening 120c of the infusion channel 120a, so that the cleaning liquid directly enters the infusion channel 120a from the infusion opening 120c and then flows out from the outlet 120b; alternatively, the brush unit 100 also includes an infusion tube 400, one end of which is connected to the liquid storage tank 300, and the infusion tube 400 also extends into the infusion channel 120a, and the other end of the infusion tube 400 is fixed to the outlet 120b, so as to transport the cleaning liquid in the liquid storage tank 300 to the outlet 120b and then to the vessel 20, so that the infusion is convenient.

Optionally, the surface of the second section 1212 of the brush rod 121 is provided with an infusion opening 120c, the infusion channel 120a penetrates the brush rod 121 along the axial direction of the brush rod 121, and the infusion channel 120a, the liquid outlet 120b and the infusion opening 120c are coaxial. The telescopic assembly 110 has a mounting channel 110a, and one end of the brush 120 having the infusion opening 120c (i.e., the second section 1212 of the brush rod 121) extends to the mounting channel 110a and is mounted on the telescopic assembly 110. The infusion tube 400 extends from the infusion opening 120c to the infusion channel 120a and communicates with the liquid storage tank 300, so as to facilitate the routing of the infusion tube 400, prevent the infusion tube 400 from interfering with the movement of the telescopic assembly 110 and the brush rod 121, and make the flow path of the cleaning liquid smooth.

The cleaning brush structure 10 includes a first shell 500, the first shell 500 has a plurality of first grooves 510 corresponding to the plurality of brush units 100, the telescopic assembly 110 is disposed in the first groove 510, the bottom wall of the first groove 510 is provided with a wiring opening, and the infusion tube 400 passes through the wiring opening and is connected to the liquid storage tank 300. Optionally, the infusion tubes 400 of the plurality of brush units 100 can be connected to the same liquid storage tank 300, and the cleaning brush structure 10 further includes a liquid inlet tube 600 connected to the liquid storage tank 300, and the cleaning liquid is transported into the liquid storage tank 300 by the liquid inlet tube 600, and the cleaning liquid in the liquid storage tank 300 is diverted to the liquid outlet 120b through the plurality of liquid infusion tubes 400 and transported to the surface of the vessel 20.

Optionally, the groove side wall surface 511 of the first groove 510 is parallel to the preset direction X, so as to guide the telescopic assembly 110 to drive the brush 120 to move along the preset direction X, so that the brush 120 can move smoothly in the preset direction X.

Optionally, the telescopic assembly 110 includes an elastic member 111 and a first pressing block 112, and the telescopic assembly 110 drives the brush 120 to move along the preset direction X by elastic deformation. Specifically, the first pressing block 112 has an installation channel 110a, and the brush 120 extends to the installation channel 110a and is installed on the first pressing block 112. One end of the elastic member 111 is connected to the bottom wall of the first groove 510, and the other end is connected to the first pressing block 112. The elastic member 111 is elastic, and the outer peripheral wall surface of the first pressing block 112 is in contact with the groove side wall surface 511 of the first groove 510, so that when the brush 120 has a tendency to move along the preset direction X, the first pressing block 112 acts on the elastic member 111 under the drive of the brush 120, so that the elastic member 111 can be extended and retracted in the preset direction X. In the preset direction X, the first pressing block 112 completely covers the elastic member 111, so that the elastic member 111 can be smoothly extended and retracted in the preset direction X.
