Description

Technical Field

[0001] This application relates to the field of household appliance technology, specifically to roller assemblies and cleaning equipment. Background Technology

[0002] To achieve better cleaning results and dissolve stains on the ground, existing cleaning equipment heats water and sprays it onto a roller. The heated water adheres to the roller and then comes into contact with the ground as the roller rolls, dissolving the stains. However, because the water needs to be heated during the process, the cleaning equipment consumes a lot of energy and there is room for improvement. Utility Model Content

[0003] In view of this, this application provides a roller assembly and a cleaning device to solve the technical problem of high energy consumption in existing cleaning devices.

[0004] In a first aspect, this application provides a roller assembly for cleaning equipment, the roller assembly comprising:

[0005] The drum body has a cylindrical structure with openings at both ends;

[0006] The motor is located inside the drum body, and its output end is connected to the drum body to drive the drum body to rotate.

[0007] A heat-conducting component is installed on the roller body and is used to guide the heat inside the roller body to the outer surface of the roller body.

[0008] Beneficial effects: The roller assembly proposed in this application places the motor used to drive the rotation of the roller body inside the roller body, and uses the heat-conducting component provided on the roller body to guide the heat generated by the operation of the motor inside the roller body to the outer surface of the roller body. This heat is used to heat the structure or water on the outer surface of the roller body, thereby achieving the heating and drying of the cleaning components provided on the outer surface of the roller body, or the heating of the water adhering to the outer surface of the roller body.

[0009] Since the heating of the outer surface of the roller body utilizes the heat generated by the motor operation, there is no need to set up a separate heating structure. This not only reduces the energy consumption of the cleaning equipment, but also simplifies the structure of the cleaning equipment and reduces the production cost of the cleaning equipment.

[0010] Since the heat emitted by the motor can be directly transferred to the outer surface of the drum through the heat-conducting components, the heat transfer does not require a complex mechanical structure, resulting in high heat utilization efficiency and further reducing the energy consumption of the cleaning equipment. At the same time, the elimination of the need for a complex heat transfer structure further simplifies the structure of the cleaning equipment and reduces its production cost.

[0011] Furthermore, the heat-conducting component can quickly direct the heat dissipated by the motor to the outer surface of the roller body, thereby improving the heat dissipation of the motor, increasing the heat dissipation area of ​​the motor, ensuring the heat dissipation effect of the motor, and improving the service life of the motor.

[0012] In one alternative embodiment, the heat-conducting element includes a heat-conducting mesh embedded within the drum body.

[0013] Beneficial effects: By using a heat-conducting mesh embedded within the roller body to transfer heat from the inside of the roller body to its outer surface, heat transfer can be achieved while ensuring uniform heat distribution across the roller body. Furthermore, using a heat-conducting mesh for heat transfer avoids the significant impact of heat transfer components on the roller body's own mass. Moreover, the heat-conducting mesh embedded within the roller body allows for its fixation and protection, preventing damage and deformation from external environmental factors.

[0014] In one alternative embodiment, the motor includes: a motor housing, through which the motor dissipates heat, and a roller body disposed outside the motor housing, with the motor housing located close to the roller body.

[0015] Beneficial effects: The heat generated during motor operation is dissipated outward through the motor housing. The motor housing is located close to the drum body, which ensures that the heat dissipated by the motor can be quickly absorbed by the heat-conducting components on the drum body and transferred to the outer surface of the drum body. This avoids the space between the motor housing and the drum body from obstructing heat transfer, reducing the efficiency of heat transfer, and reducing the heat dissipation effect of the motor.

[0016] In one alternative embodiment, the motor includes a rotor assembly and a stator assembly, the rotor assembly being disposed outside the stator assembly, and a roller body being sleeved outside the rotor assembly and rotating synchronously with the rotor assembly.

[0017] Beneficial effects: For motors with an external rotor structure, the drum body can be formed as part of the motor rotor, which not only further simplifies the structure of the drum assembly, but also allows the heat generated by the motor to be directly transferred to the drum body, further simplifying the heat transfer process and ensuring that the heat can be quickly transferred to the outer surface of the drum body, thereby achieving rapid heat dissipation of the motor and efficient utilization of heat.

[0018] In one alternative embodiment, the motor includes: a control component, the control component integrating a circuit board of the motor, and at least a portion of a heat-conducting element disposed close to the control component.

[0019] Beneficial effects: In the motor structure, the control components generate a large amount of heat during operation. Rapidly transferring this heat to the outer surface of the drum body improves the motor's heat dissipation, prevents heat accumulation on the stator assembly, extends the motor's lifespan, and also increases the heating efficiency of the drum assembly. Therefore, by placing at least a portion of the heat-conducting element close to the control components, the heat generated by the control components can be quickly absorbed by this portion of the heat-conducting element and diffused throughout the entire element, rapidly transferring the heat generated during the control components' operation to the outer surface of the drum body.

[0020] In one alternative embodiment, a cleaning element is provided on the outer side of the roller body, the cleaning element being capable of absorbing water.

[0021] Beneficial effects: The cleaning components can absorb water, meaning that water can adhere to the cleaning components for a longer period of time. The heat generated by the motor can be continuously transferred to the cleaning components on the outer surface of the roller body during operation, and continuously heat the water attached to the cleaning components. This ensures that the water temperature attached to the cleaning components can be significantly increased after a period of heating. The heated water participates in the cleaning process, resulting in a better cleaning effect.

[0022] In one alternative embodiment, the roller assembly further includes a heating element capable of directly heating the heat-conducting element.

[0023] Beneficial effects: In some cases, the motor may only occupy a portion of the space defined by the drum body. The part of the drum body closer to the motor is fully heated and has a better heating effect, while the part of the drum body farther from the motor has a poor heating effect and cannot effectively heat the water or structure on the outside. Therefore, heating elements can be set separately to heat the heat-conducting elements set in this part to ensure that all parts of the drum body can heat up and heat the outer structure or water on the outside.

[0024] In one alternative embodiment, the roller assembly further includes: roller supports, which are disposed on both sides of the roller body, and the roller body is rotatably disposed between the two roller supports.

[0025] Beneficial effects: The roller assembly is fixed to the cleaning equipment by the roller bracket. The roller bracket is fixedly set. During operation, the motor drives the roller body to rotate. The roller body is rotatably set between the two roller brackets.

[0026] In a second aspect, this application provides a cleaning device, including a spray assembly and a roller assembly according to the first aspect of this application, wherein the spray assembly is used to spray water onto the surface of the roller assembly.

[0027] In one alternative implementation, the spray position of the spray assembly on the roller assembly should be higher than the ground plane of the roller assembly.

[0028] Therefore, the water sprayed from the spray unit onto the roller assembly does not flow directly to the ground, but is absorbed by the roller assembly and heated by it. The roller assembly then uses the heated water to clean the ground, ensuring a cleaning effect. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "communication" should be interpreted broadly. For example, they can refer to fixed communication, detachable communication, or integral communication; they can refer to mechanical communication or electrical communication; they can refer to direct connection or indirect connection through an intermediate medium; they can refer to communication within two components; and they can refer to wireless communication or wired communication. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] To achieve better cleaning results and dissolve stains on the ground, existing cleaning equipment heats water and sprays it onto a roller. The heated water adheres to the roller and then comes into contact with the ground as the roller rolls, dissolving the stains. Because the water needs to be heated during the process, the cleaning equipment consumes a lot of energy.

[0044] To reduce the energy consumption of cleaning equipment, the roller assembly proposed in this application places the motor inside the cylinder defined by the roller assembly body, and directly uses the heat dissipated by the motor operation to heat the structure outside the roller body or the water. This not only reduces the energy consumption of the cleaning equipment, but also simplifies the structure of the cleaning equipment and reduces the production cost of the cleaning equipment.

[0045] The following is combined with Figures 1 to 5 This describes an embodiment of the present application.

[0046] like Figures 1-4 As shown, according to an embodiment of this application, in one aspect, this application provides a roller assembly 100, including: a roller body 10, a motor 20, and a heat-conducting component 30.

[0047] The roller body 10 has a cylindrical structure with openings at both ends. The motor 20 is located inside the roller body 10 and its output end is connected to the roller body 10 to drive the roller body 10 to rotate. The heat-conducting component 30 is located on the roller body 10 and is used to guide the heat generated by the operation of the motor 20 to the outer surface of the roller body 10.

[0048] In this embodiment, the roller assembly 100 proposed in this application places the motor 20 for driving the roller body 10 to rotate inside the roller body 10, and uses the heat-conducting element 30 provided on the roller body 10 to guide the heat generated by the operation of the motor 20 inside the roller body 10 to the outer surface of the roller body 10. The heat is used to heat the structure or water on the outer surface of the roller body 10, thereby heating and drying the cleaning element 40 provided on the outer surface of the roller body 10, or heating the water attached to the outer surface of the roller body 10.

[0049] Since the heating of the outer surface of the roller body 10 utilizes the heat generated by the operation of the motor 20, there is no need to set up a separate heating structure. This not only reduces the energy consumption of the cleaning equipment, but also simplifies the structure of the cleaning equipment and reduces the production cost of the cleaning equipment.

[0050] Since the heat emitted by the motor 20 can be directly transferred to the outer surface of the drum through the heat-conducting component 30, the heat transfer does not require a complex mechanical structure, resulting in high heat utilization efficiency and further reducing the energy consumption of the cleaning equipment. At the same time, the absence of a complex heat transfer structure further simplifies the structure of the cleaning equipment and reduces its production cost.

[0051] Furthermore, the heat-conducting component 30 can quickly guide the heat dissipated by the motor 20 to the outer surface of the roller body 10, thereby better dissipating the heat from the motor 20, increasing the heat dissipation area of ​​the motor 20, ensuring the heat dissipation effect of the motor 20, and improving the service life of the motor 20.

[0052] It should be noted that the embodiments of this application do not limit the specific structure of the roller body 10, motor 20 and heat-conducting component 30 of the roller assembly 100. This is because the main improvement of this application is that the heat generated by the operation of the motor 20 inside the roller body 10 is transferred to the outer surface of the roller body 10 through the heat-conducting component 30. The heat generated by the operation of the motor 20 is used to heat the structure and water on the outer surface of the roller body 10, thereby utilizing the heat generated by the operation of the motor 20 and reducing the energy consumption of the cleaning equipment. As for the specific structure of the roller body 10, motor 20 and heat-conducting component 30, it can be set according to the specific structure and actual use environment. These adjustments are all within the protection scope of the embodiments of this application.

[0053] The following is through Figures 1 to 5The embodiments illustrate preferred embodiments of the specific structures of the drum body 10, the motor 20, and the heat-conducting element 30.

[0054] like Figure 4 As shown, in some embodiments, the heat-conducting element 30 includes a heat-conducting mesh embedded within the roller body 10.

[0055] In the above embodiments, the heat inside the roller body 10 is transferred to the outer surface of the roller body 10 by a heat-conducting mesh embedded within the roller body 10, ensuring uniform heat distribution on the roller body 10 while achieving heat transfer. Furthermore, using a heat-conducting mesh for heat transfer avoids the heat transfer from the heat-conducting component 30 significantly affecting the mass of the roller body 10 itself. Moreover, the heat-conducting mesh embedded within the roller body 10 allows the roller body 10 to fix and protect the heat-conducting mesh, preventing damage and deformation under external environmental conditions.

[0056] In other embodiments, the roller body 10 itself may be formed as a heat-conducting element 30, that is, the roller body 10 itself is made of a material with good thermal conductivity, so as to better guide the heat inside the roller body 10 to the outer surface of the roller body 10.

[0057] like Figure 2 and Figure 3 As shown, in some embodiments, the motor 20 includes: a motor housing 21, through which the motor 20 dissipates heat to the outside, and the roller body 10 is disposed outside the motor housing 21, with the motor housing 21 disposed close to the roller body 10.

[0058] In the above embodiment, the heat generated by the motor 20 during operation is dissipated outward and through the motor housing 21 to the outside of the motor 20. The motor housing 21 is located close to the roller body 10, which can ensure that the heat dissipated by the motor 20 can be quickly absorbed by the heat-conducting component 30 provided on the roller body 10 and transferred to the outer surface of the roller body 10. This avoids the space between the motor housing 21 and the roller body 10 from hindering the heat transfer, reducing the efficiency of heat transfer, and reducing the heat dissipation effect of the motor 20.

[0059] In some embodiments, a heat-conducting material may be filled between the motor housing 21 and the drum body 10 to better direct the heat generated by the motor 20 to the heat-conducting component 30 provided on the drum body 10.

[0060] In one alternative embodiment, the motor 20 includes a rotor assembly 22 and a stator assembly 23, the rotor assembly 22 being disposed outside the stator assembly 23, and the roller body 10 being sleeved outside the rotor assembly 22 and rotating synchronously with the rotor assembly 22.

[0061] In the above embodiments, for the motor 20 with an external rotor structure, the drum body 10 can be formed as part of the rotor of the motor 20. This not only further simplifies the structure of the drum assembly 100, but also allows the heat generated by the operation of the motor 20 to be directly transferred to the drum body 10, further simplifying the heat transfer process and ensuring that the heat can be quickly transferred to the outer surface of the drum body 10, thereby achieving rapid heat dissipation of the motor 20 and efficient utilization of heat.

[0062] In some embodiments, the motor 20 includes: a control component, the control component integrating a circuit board on which the motor 20 is disposed, and at least a portion of the heat-conducting component 30 is disposed close to the control component.

[0063] In the above embodiment, in the structure of motor 20, the operation of the control component generates a large amount of heat. Rapidly transferring this heat to the outer surface of the drum body 10 improves the heat dissipation of motor 20, prevents heat accumulation on the stator assembly 23 of motor 20, extends the service life of motor 20, and also improves the heating efficiency of drum assembly 100. Therefore, by placing at least a portion of the heat-conducting element 30 close to the control component, this portion of the heat-conducting element 30 can quickly absorb the heat generated by the operation of the control component and diffuse the heat throughout the entire heat-conducting element 30, rapidly transferring the heat generated during the operation of the control component to the outer surface of drum body 10.

[0064] In some embodiments, the heat-conducting element 30 is a heat-conducting mesh, which is more densely distributed near the control component and has smaller mesh size near the control component, so that the heat-conducting element 30 at the control component has a larger area for absorbing heat.

[0065] like Figure 2 and Figure 3 As shown, in some embodiments, a cleaning element 40 is provided on the outer side of the roller body 10, which can absorb water.

[0066] In the above embodiment, the cleaning component 40 can absorb water, that is, water can adhere to the cleaning component 40 for a longer time. The heat generated by the operation of the motor 20 can be continuously transferred to the cleaning component 40 provided on the outer surface of the roller body 10 during the operation, and continuously heat the water attached to the cleaning component 40, ensuring that the water temperature attached to the cleaning component 40 can be significantly increased after a period of heating. The heated water participates in the cleaning process and has a better cleaning effect.

[0067] The cleaning component 40 can be a cleaning cloth, brush, etc., and there are no restrictions on its use.

[0068] In some embodiments, the roller assembly 100 further includes a heating element capable of directly heating the heat-conducting element 30.

[0069] In some cases, the motor 20 may only occupy a portion of the space defined by the drum body 10. The part of the drum body 10 closer to the motor 20 is fully heated and has a better heating effect, while the part of the drum body 10 farther from the motor 20 has a poor heating effect and cannot effectively heat the water or structure on the outside. Therefore, in the above embodiment, a heating element can be set separately to heat the heat-conducting element 30 set in this part to ensure that all parts of the drum body 10 can heat up and heat the outer structure or the water on the outside.

[0070] like Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the roller assembly 100 further includes a roller bracket 50, which is disposed on both sides of the roller body 10, and the roller body 10 is rotatably disposed between the two roller brackets 50.

[0071] In the above embodiment, the roller assembly 100 is fixed to the cleaning equipment by the roller bracket 50. The roller bracket 50 is fixedly set. During operation, the motor 20 drives the roller body 10 to rotate. The roller body 10 is rotatably set between the two roller brackets 50.

[0072] In some embodiments, to avoid heat transfer to the roller support 50, the roller body 10 is not provided with a heat-conducting element 30 near the edge of the roller support 50.

[0073] The following reference Figures 1-5 The roller assembly 100 described in the embodiments of this application is used to describe this application.

[0074] like Figure 2 As shown, the entire roller assembly 100 mainly consists of a roller body 10, a cleaning component 40, a roller support 50, a motor 20, and a heat-conducting component 30.

[0075] The drum body 10 has a cylindrical structure with openings at both ends. The motor 20 is located inside the drum body 10. The output end of the motor 20 is connected to the drum body 10 to drive the drum body 10 to rotate. The heat-conducting mesh embedded in the drum body 10 directs the heat generated by the operation of the motor 20 to the outer surface of the drum body 10.

[0076] The motor 20 includes a stator assembly 23, a rotor assembly 22 and a motor housing 21. The motor 20 dissipates heat to the outside through the motor housing 21. The drum body 10 is located outside the motor housing 21 and the motor housing 21 is located close to the drum body 10.

[0077] The stator assembly 23 is fixedly mounted inside the drum body 10 via a rotating shaft and a base. The rotor assembly 22 is rotatably mounted at the end of the stator assembly 23 via a bearing. The rotor assembly 22 is configured as the output end of the motor 20 and is connected to the drum body 10 to drive the drum body 10 to rotate.

[0078] Roller supports 50 are located on both sides of the roller body 10, and the roller body 10 is rotatably positioned between the two roller supports 50. A cleaning component 40, which is a brush, is provided on the outer side of the roller body 10. The brush can absorb water.

[0079] In the above embodiment, the heat emitted by the motor 20 inside the roller body 10 through the motor housing 21 is transferred to the brushes on the outer surface of the roller body 10 by the heat-conducting mesh embedded in the roller body 10. The water droplets attached to the brushes are heated and used to clean the floor. The high temperature water can better dissolve dirt, thereby making the cleaning effect of the cleaning equipment better.

[0080] Secondly, this application provides a cleaning device, which includes a spray assembly 200 and a roller assembly 100 according to the first aspect of this application. The spray assembly 200 is used to spray water onto the surface of the roller assembly 100 so that the surface of the roller assembly 100 of the cleaning device is kept moist. Cleaning is performed using the moist roller assembly 100, resulting in higher cleaning efficiency.

[0081] In one alternative implementation, such as Figure 5 As shown, the spray position of the spray assembly 200 on the roller assembly 100 should be higher than the grounding plane of the roller assembly 100.

[0082] In the above embodiment, the water sprayed by the spray assembly 200 onto the roller assembly 100 does not flow directly to the ground, but is absorbed by the roller assembly 100 and heated by the roller assembly 100. The roller assembly 100 uses the heated water to clean the ground, ensuring the cleaning effect.

[0083] In this embodiment, the cleaning device proposed in this application has all the technical effects of the roller assembly 100 of this application, and will not be described in detail here.

[0084] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
