Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more particularly to a cleaning device. Background Technology

[0002] Floor scrubbers, carpet cleaners, and other floor cleaning equipment are widely used in various scenarios such as homes, commercial supermarkets, and industrial workshops.

[0003] In related technologies, in order to improve the stain removal effect and enhance the deep cleaning capability during the cleaning process, a heater is usually installed in the cleaning equipment to heat the cleaning water before the cleaning operation is carried out.

[0004] However, in related technologies, using a heater alone to heat the cleaning water results in high heating power consumption and high overall power consumption, which seriously affects the working life of cleaning equipment that uses battery packs. Summary of the Invention

[0005] In view of the above problems, this application provides a cleaning device to solve the technical problems of high heating power consumption and large overall power consumption of existing cleaning devices, which leads to increased equipment usage costs, thereby effectively reducing energy consumption, improving energy utilization efficiency, and reducing the usage cost of cleaning devices.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] This application provides a cleaning device, including:

[0008] The fuselage, including the motor and battery pack;

[0009] A floor brush assembly is connected to the main body; the floor brush assembly includes a roller brush, which is used to perform floor cleaning function.

[0010] The water system assembly includes an inlet pipe, a heat exchange unit, and an outlet pipe connected in sequence; the inlet end of the inlet pipe is used to connect to a water source, and the outlet end of the outlet pipe faces the roller brush and / or the surface to be cleaned.

[0011] The heat exchange unit is in close proximity to at least one of the motor surface and the battery pack, so that the heat generated by the motor and at least one of the battery pack can heat the water flowing through the heat exchange unit.

[0012] In the cleaning equipment provided in this application embodiment, a heat exchange unit is set in the water circuit component. The heat exchange unit exchanges heat with at least one of the motor and battery pack in close proximity. This can quickly increase the temperature of the water flowing through the heat exchange unit, thereby achieving efficient recovery and utilization of waste heat generated by the motor and battery pack. This reduces the start-up frequency of the heater in the cleaning equipment, thereby reducing the heating power consumption and overall power consumption of the cleaning equipment. For cleaning equipment using battery packs, this can extend the working time of the entire machine, thereby reducing the operating cost of the cleaning equipment.

[0013] In some optional embodiments, the heat exchange unit includes a first heat exchange plate, and the first heat exchange plate has a first heat exchange cavity inside;

[0014] The first heat exchange plate is connected between the water inlet pipe and the water outlet pipe, and is close to the surface of the motor, so that the heat generated by the motor can heat the water in the first heat exchange chamber.

[0015] This increases the contact area between the heat exchange unit and the motor, thereby enhancing the waste heat transfer efficiency, allowing the waste heat to be fully absorbed, and further reducing the heating energy consumption of the cleaning equipment.

[0016] In some optional embodiments, the heat exchange unit includes a second heat exchange plate, and the second heat exchange plate has a second heat exchange cavity inside;

[0017] The second heat exchange plate is connected between the water inlet pipe and the water outlet pipe, and is close to the surface of the battery pack, so that the heat generated by the battery pack heats the water in the second heat exchange chamber.

[0018] This increases the contact area between the heat exchange unit and the battery pack, thereby enhancing the waste heat transfer efficiency, allowing for full absorption of waste heat, and further reducing the heating energy consumption of the cleaning equipment.

[0019] In some alternative embodiments, the water circuit assembly further includes a preheating pipe located between the heat exchange unit and the outlet pipe; the preheating pipe is close to at least a portion of the inlet pipe so that water flowing through the preheating pipe can heat water flowing through the inlet pipe.

[0020] In this way, the preheating pipe and the water inlet pipe achieve heat exchange, so that the heat on the surface of the preheating pipe can be transferred to the water in the water in the water inlet pipe, avoiding the loss of heat of the water flowing in the preheating pipe through the preheating pipe, further improving the heat utilization rate, and thus further reducing the heating energy consumption of the cleaning equipment.

[0021] In some optional embodiments, the preheating pipe is at least partially sleeved on the outer periphery of the water inlet pipe, so that a closed annular cavity is formed between the inner peripheral wall of the preheating pipe and the outer peripheral wall of the water inlet pipe, and the annular cavity is connected to the water outlet end of the water inlet pipe.

[0022] This effectively increases the contact area between the preheating pipe and the water inlet pipe, thereby improving their heat exchange rate.

[0023] In some alternative embodiments, the preheating tube is spirally wound around the outer peripheral wall of the water inlet pipe, at least partially along the extension direction of the water inlet pipe.

[0024] In this way, while increasing the contact area between the preheating pipe and the water inlet pipe, the manufacturing difficulty of both can be reduced, thereby reducing the manufacturing cost of the cleaning equipment.

[0025] In some alternative embodiments, the water circuit assembly further includes a heater connected between the heat exchange unit and the outlet pipe, the heater being used to heat the cleaning water flowing from the heat exchange unit to the outlet pipe.

[0026] In this way, the waste heat from the motor and battery pack is used to preheat the cleaning water, and then the water is heated by the heater as needed. This reduces the start-up frequency of the heater, thereby reducing the heating power consumption of the heater, reducing the power consumption of the cleaning equipment, and thus reducing the operating cost of the cleaning equipment.

[0027] In some alternative embodiments, the water circuit assembly further includes a control valve and a spray head, the control valve having an inlet, a first outlet, and a second outlet, the inlet of the control valve being selectively connected to one of the first outlet and the second outlet.

[0028] The water circuit assembly further includes a cold water pipe; the inlet of the control valve is connected to the outlet of the heat exchange unit; the first outlet is connected to the inlet of the heater; the outlet of the water pipe is connected to the spray head; the second outlet is connected to the inlet of the cold water pipe; and the outlet of the cold water pipe faces the roller brush or the surface to be cleaned. Alternatively,

[0029] The water outlet pipe includes a first sub-water outlet pipe and a second sub-water outlet pipe;

[0030] The inlet of the control valve is connected to the outlet of the heater, the first outlet is connected to the inlet of the first sub-outlet pipe, and the outlet of the first sub-outlet pipe faces the roller brush or the floor to be cleaned; the second outlet is connected to the inlet of the second sub-outlet pipe, and the outlet of the second sub-outlet pipe is connected to the spray head.

[0031] In this way, the switching logic of the control valve enables dynamic control of the temperature of the clean water, thereby improving the applicability of the equipment to different scenarios and the ease of operation for users.

[0032] In some alternative embodiments, the cleaning device further includes a control unit electrically connected to both the control valve and the heater, the control unit being used to control the opening and closing of the control valve and the heating temperature of the heater.

[0033] This further enhances the intelligence of cleaning equipment, thereby improving the user experience.

[0034] In some alternative embodiments, the water outlet pipe is disposed close to the machine body so that the heat generated by the friction between the roller brush and the ground is transferred through the machine body to the water outlet pipe to heat the cleaning water in the water outlet pipe;

[0035] And / or,

[0036] The water circuit assembly also includes a clean water tank, which is disposed on the floor brush assembly or the body, and the water inlet end of the water inlet pipe is connected to the clean water tank.

[0037] This effectively utilizes the waste heat generated by the friction between the roller brush and the ground, thereby further reducing heating power consumption and the power consumption of the cleaning equipment. In addition, the cleaning equipment comes with a clean water tank, which supplies water to the water circuit components, eliminating the need for an external water source, further expanding the applicability of the cleaning equipment and enhancing the user experience.

[0055] 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. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0056] Floor scrubbers, carpet cleaners, and other floor cleaning equipment are widely used in various settings such as homes, commercial supermarkets, and industrial workshops. Typically, to improve stain removal and enhance deep cleaning capabilities, a heater is incorporated into the cleaning equipment to heat the cleaning water before the cleaning process. However, using a heater alone to heat the cleaning water results in high heating power consumption and high overall power consumption, which significantly impacts the operating time of battery-powered cleaning equipment.

[0057] To overcome the above-mentioned defects, this application provides a cleaning device that, by setting a heat exchange unit in the water circuit assembly, and by exchanging heat in close proximity with at least one of the motor and the battery pack, can quickly increase the temperature of the water flowing through the heat exchange unit, thereby achieving efficient recovery and utilization of waste heat. This reduces the start-up frequency of the heater in the cleaning device, thereby reducing the heating power consumption and overall power consumption of the cleaning device. For cleaning devices using battery packs, this can extend the operating time of the entire machine, thereby reducing the operating cost of the cleaning device.

[0058] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0059] First, it should be noted that in the embodiments of this application, in order to more clearly demonstrate the structure of the cleaning equipment and the layout of the water circuit components, wherein, Figure 3 Some components of the cleaning equipment are displayed outside the machine, removed from the main body and floor brush assembly. These include the heater, control valves, and preheating pipes. Figure 5 and Figure 6 A block diagram is used to illustrate the water flow path of the water system components.

[0060] Please refer to Figure 1 As shown in the figure, this application embodiment provides a cleaning device 10, which includes, but is not limited to, a sweeping robot, a floor scrubber, a washer-mop combo, etc. The cleaning device 10 includes a body 100 and a floor brush assembly 200. The floor brush assembly 200 is connected to the body 100 and includes a floor brush housing and a roller brush 210 rotatably disposed within the floor brush housing. An air inlet is provided at the bottom of the floor brush housing to enable the roller brush 210 to perform the cleaning function on the floor. The structure and principle of the cleaning device 10 to perform the cleaning function can be referred to in related technologies, and will not be repeated here.

[0061] Usually, such as Figure 2 and Figure 3As shown, the body 100 includes a motor 110 and a battery pack 120. The motor 110 provides power for the cleaning function of the cleaning device 10, and the battery pack 120 supplies power to the cleaning device 10, such as the motor 110 and other electronic components.

[0062] To improve the cleaning effect of the cleaning device 10, in some embodiments, please refer to... Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the cleaning equipment 10 also includes a water circuit assembly 300, which is a piping system for transporting and heating cleaning water; wherein, the cleaning water can be clean water or a liquid with added cleaning solution, which are collectively referred to as water.

[0063] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the water circuit assembly 300 includes an inlet pipe 310, a heat exchange unit 320, and an outlet pipe 330 connected in sequence; the inlet end of the inlet pipe 310 is used to connect to a water source, and the outlet end of the outlet pipe 330 faces the roller brush 210 and / or the floor to be cleaned; wherein, the heat exchange unit 320 is close to at least one of the surface of the motor 110 and the battery pack 120, so that the heat generated by at least one of the motor 110 and the battery pack 120 can heat the water flowing through the heat exchange unit 320.

[0064] It is understandable that when the cleaning equipment 10 is running, the motor 110 and the battery pack 120 will generate waste heat, which will affect the service life and performance of the motor 110, the battery pack 120 and the various electronic components in the cleaning equipment 10. Therefore, it is usually necessary to install heat sinks or cooling fans to discharge the generated waste heat into the environment, which will lead to energy waste.

[0065] Therefore, in this embodiment, by setting a heat exchange unit 320 in the water circuit component 300, and by exchanging heat with at least one of the motor 110 and the battery pack 120 in close proximity, the temperature of the water flowing through the heat exchange unit 320 can be quickly increased, so as to achieve efficient recovery and utilization of waste heat. In this way, the start-up frequency of the heater 350 in the cleaning equipment 10 can be reduced, thereby reducing the heating power consumption and overall power consumption of the cleaning equipment 10. For the cleaning equipment 10 using the battery pack 120, the working time of the whole machine can be extended, thereby reducing the operating cost of the cleaning equipment 10.

[0066] In other words, when the cleaning equipment 10 is cleaning the floor, if the cleaning water needs to be heated, the waste heat generated by the motor 110 and battery pack 120 can be transferred to the cleaning water flowing through the heat exchange unit 320 to raise the temperature of the cleaning water. For example, the temperature of the cleaning water can be raised to 35~50℃, thereby reducing the heating energy consumption of the heater 350 in the cleaning equipment 10 and reducing the power consumption required for heating. At the same time, the temperature of the motor 110 and battery pack 120 is reduced, extending the service life of the motor 110 and battery pack 120. There is no need to install heat sinks, cooling fans or other heat dissipation devices in the cleaning equipment 10, realizing integrated thermal management of the cleaning equipment 10, effectively utilizing the waste heat generated in the cleaning equipment 10, and reducing the manufacturing and operating costs of the cleaning equipment 10.

[0067] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the heat exchange unit 320 includes a first heat exchange plate 321, which has a first heat exchange chamber through which cleaning water can flow. The first heat exchange plate 321 is connected between the inlet pipe 310 and the outlet pipe 330 and is close to the surface of the motor 110 so that the heat generated by the motor 110 can heat the water in the first heat exchange chamber. In this way, the waste heat generated by the motor 110 can be transferred to the cleaning water flowing through the first heat exchange chamber through the first heat exchange plate 321 to increase the temperature of the cleaning water, thereby effectively utilizing the waste heat generated by the motor 110 and avoiding energy waste. In addition, by making the first heat exchange plate 321 close to the surface of the motor 110, the contact area between the heat exchange unit 320 and the motor 110 can be increased, thereby enhancing the waste heat transfer efficiency, allowing the waste heat to be fully absorbed, and further reducing the heating energy consumption of the cleaning equipment 10.

[0068] It should be noted that "the first heat exchange plate 321 is close to the surface of the motor 110" means that the two are directly attached or the gap between them is extremely small, with no large area of ​​heat-insulating air layer between them, so that heat exchange can occur efficiently between the first heat exchange plate 321 and the surface of the motor 110; or, the first heat exchange plate 321 and the surface of the motor 110 are connected by heat conduction through, for example, a thermally conductive silicone pad or a thermally conductive film, to achieve rapid heat transfer.

[0069] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the heat exchange unit 320 includes a second heat exchange plate 322, and a second heat exchange chamber is provided in the second heat exchange plate 322. The second heat exchange plate 322 is connected between the water inlet pipe 310 and the water outlet pipe 330, and is close to the surface of the battery pack 120, so that the heat generated by the battery pack 120 heats the water in the second heat exchange chamber. In this way, the waste heat generated by the battery pack 120 can be transferred to the cleaning water flowing through the second heat exchange chamber through the second heat exchange plate 322 to increase the temperature of the cleaning water, thereby effectively utilizing the waste heat generated by the motor 110 and avoiding energy waste. In addition, by setting the second heat exchange plate 322 close to the battery pack 120, the contact area between the heat exchange unit 320 and the battery pack 120 can be increased, thereby enhancing the waste heat transfer efficiency, allowing the waste heat to be fully absorbed, and further reducing the heating energy consumption of the cleaning equipment 10.

[0070] It is understandable that the close proximity of the second heat exchange plate 322 to the battery pack 120 means that the surface of the second heat exchange plate 322 is adjacent to the outer heating wall of the battery pack 120, with a very small or no gap between them and no large-area heat-insulating air layer, so as to ensure that the waste heat generated by the battery pack 120 can be efficiently conducted to the second heat exchange plate 322 through which the circulating fluid flows; of course, the second heat exchange plate 322 and the battery pack 120 can also conduct heat through the setting of thermally conductive silicone pads, thermally conductive films, etc., to achieve rapid heat transfer.

[0071] For example, the first heat exchange plate 321 and the second heat exchange plate 322 include, but are not limited to, aluminum plates, aluminum alloy plates, copper plates, copper plates, aluminum-copper composite plates, graphite composite metal plates, etc.

[0072] In some embodiments, such as Figure 3 As shown, the water circuit assembly 300 also includes a preheating pipe 340, which is located between the heat exchange unit 320 and the outlet pipe 330. That is, the temperature of the water in the preheating pipe 340 is higher than the temperature of the water in the inlet pipe 310. By bringing the preheating pipe 340 close to at least part of the inlet pipe 310, the preheating pipe 340 and the inlet pipe 310 can exchange heat, so that the heat on the surface of the preheating pipe 340 can be transferred to the water in the inlet pipe 310 through the inlet pipe 310. This prevents the heat of the water flowing in the preheating pipe 340 from being lost through the preheating pipe 340, and at the same time increases the temperature of the water in the inlet pipe 310, further improving the heat utilization rate, thereby further reducing the heating energy consumption of the cleaning equipment 10.

[0073] An example, such as Figure 3 and Figure 4 As shown, the preheating pipe 340 is at least partially sleeved on the outer periphery of the water inlet pipe 310, so that a closed annular cavity is formed between the inner peripheral wall of the preheating pipe 340 and the outer peripheral wall of the water inlet pipe 310. The annular cavity is connected to the water outlet end of the water inlet pipe 310. In this way, the contact area between the preheating pipe 340 and the water inlet pipe 310 can be effectively increased, thereby improving the heat exchange rate between the two.

[0074] In another example, the preheating pipe 340 is spirally wound around the outer peripheral wall of the water inlet pipe 310 at least partially along the extension direction of the water inlet pipe 310. In this way, while increasing the contact area between the preheating pipe 340 and the water inlet pipe 310, the manufacturing difficulty of both can be reduced, thereby reducing the manufacturing cost of the cleaning equipment 10.

[0075] like Figure 3 , Figure 5 and Figure 6 As shown, the water circuit assembly 300 also includes a heater 350. For example, the heater 350 includes, but is not limited to, an electric heater 350. The heater 350 is connected between the heat exchange unit 320 and the water outlet pipe 330. The heater 350 is used to heat the cleaning water flowing from the heat exchange unit 320 to the water outlet pipe 330, so that the temperature of the cleaning water reaches a preset temperature, thereby heating the roller brush 210, the floor to be cleaned, etc., and improving the effect of removing stains.

[0076] In this embodiment of the application, if it is necessary to heat the cleaning water during the cleaning operation, the cleaning water is preheated by the waste heat of the motor 110 and the battery pack 120 before the heater 350 is started. Then, the cleaning water is heated by the heater 350 as needed. This reduces the starting frequency of the heater 350, thereby reducing the heating power consumption of the heater 350, reducing the power consumption of the cleaning equipment 10, and thus reducing the operating cost of the cleaning equipment 10.

[0077] In some embodiments, such as Figure 3 , Figure 5 and Figure 6 As shown, the water circuit assembly 300 also includes a control valve 360, which has an inlet, a first outlet, and a second outlet. The inlet of the control valve 360 ​​can selectively connect to either the first outlet or the second outlet; for example, the control valve 360 ​​is a solenoid three-way valve. In this embodiment, the water circuit in the water circuit assembly 300 is switched using the control valve 360 ​​to meet the cleaning needs of users in different scenarios.

[0078] In some embodiments, such as Figure 3 As shown, the water circuit assembly 300 also includes a spray head 370, which can be installed on the front side of the cleaning equipment 10. The water output from the water circuit assembly 300 can be sprayed onto the roller brush, the ground, etc. via the spray head 370.

[0079] In some embodiments, such as Figure 6As shown, the water circuit assembly 300 also includes a cold water pipe 380. The inlet of the control valve 360 ​​is connected to the outlet of the heat exchange unit 320. The first outlet is connected to the inlet of the heater 350. The outlet of the outlet pipe 330 is connected to the spray head 370. The second outlet is connected to the inlet of the cold water pipe 380. The outlet of the cold water pipe 380 faces the roller brush 210 or the surface to be cleaned. In this way, hot water can be sprayed onto the ground to be cleaned in front of the cleaning equipment 10 through the spray head 370. When it is not necessary to spray hot water onto the ground to be cleaned, but it is necessary to spray cold water onto the surface to be cleaned or the roller brush 210, the control valve 360 ​​can be switched to the cold water pipe 380 to spray warm water preheated by the heat exchange unit 320 onto the surface to be cleaned or the roller brush 210. It can be seen that by setting different water circuits and switching them through the control valve 360, different cleaning needs of users can be met, and the user experience can be improved.

[0080] In other embodiments, such as Figure 5 As shown, the water outlet pipe 330 includes a first sub-outlet pipe 331 and a second sub-outlet pipe 332. The inlet of the control valve 360 ​​is connected to the outlet of the heater 350, and the first outlet is connected to the inlet of the first sub-outlet pipe 331. The outlet of the first sub-outlet pipe 331 faces the roller brush 210 or the floor to be cleaned. The second outlet is connected to the inlet of the second sub-outlet pipe 332, and the outlet of the second sub-outlet pipe 332 is connected to the spray head 370. Both the first sub-outlet pipe 331 and the second sub-outlet pipe 332 supply hot water to meet the hot water needs of different locations. Therefore, the switching logic of the control valve 360 ​​achieves dynamic control of the cleaning water temperature, thereby improving the applicability of the equipment and the ease of operation for users.

[0081] To further enhance the intelligence of the cleaning equipment 10, the cleaning equipment 10 also includes a control unit. The control unit is electrically connected to the control valve 360 ​​and the heater 350 respectively. The control unit is used to control the opening and closing of the control valve 360 ​​and the heating temperature of the heater 350. In this way, the intelligence of the cleaning equipment 10 is further realized, thereby improving the user experience.

[0082] In some embodiments, the water outlet pipe 330 is disposed close to the body 100 so that the heat generated by the friction between the roller brush 210 and the ground is transferred through the body 100 to the water outlet pipe 330 to heat the cleaning water in the water outlet pipe 330. This effectively utilizes the waste heat generated by the friction between the roller brush 210 and the ground, avoids energy waste, improves waste heat utilization rate, reduces the power consumption and electricity consumption of the cleaning equipment 10, and thus reduces the cost of use.

[0083] In some embodiments, such as Figure 3 , Figure 5 and Figure 6As shown, the water circuit component 300 also includes a clean water tank 390, which is mounted on the floor brush component 200 or the body 100. The water inlet end of the water inlet pipe 310 is connected to the clean water tank 390. In this way, the cleaning equipment 10 has its own clean water tank 390, which supplies water to the water circuit component 300 without the need to connect to an external water source. This further expands the applicability of the cleaning equipment 10 and enhances the user experience.

[0084] In summary, the cleaning equipment provided in this application embodiment, by setting a heat exchange unit in the water circuit component, and by exchanging heat in close proximity with at least one of the motor and battery pack, can quickly increase the temperature of the water flowing through the heat exchange unit, thereby achieving efficient recovery and utilization of waste heat. This reduces the start-up frequency of the heater in the cleaning equipment, thereby reducing the heating power consumption and overall power consumption of the cleaning equipment, and thus reducing the operating cost of the cleaning equipment.
