[0114] Although relative terms such as "upper", "lower", etc. are used herein to describe one component's relationship to another component as illustrated in the figures, these terms are used herein for ease of description only and are not intended to constrict the scope of the example embodiments. It is to be understood that if a device of the icon is turned upside down, then the component described as being "upper" would become the component described as being "lower". When a structure is "on" another structure, it can mean that the structure is formed integrally with the other structure or that the structure is "directly" on the other structure or that the structure is "indirectly" on the other structure via another structure.

[0115] The use of the terms "one" and "the" and "said" and "the" are used herein to describe one or more elements, component, etc.; the use of the terms "includes" and "having" are used herein to describe open-ended terms and are intended to mean that there can be additional elements, component, etc. beyond those listed; the use of the terms "first" and "second" and the like are used herein to describe a variety of elements, component, etc. and are not intended to limit one or more of the elements, component, etc. to a particular number of elements, component, etc.

[0116] As Figures 1 to 13As shown, some embodiments provide a cleaning device 01. The cleaning device 01 can be a scrubber, a robot sweeper, a combination of a sweeper and a mop, etc., and the present disclosure does not specifically limit it. The cleaning device 01 has good cleaning effect.

[0117] The cleaning device 01 can include a cleaning working part 1. The cleaning working part 1 can be used to clean the surface to be cleaned. The cleaning working part 1 can include a cleaning element 13, a dispensing element 11 and a fluid output element 12.

[0118] The cleaning element 13 can be in contact with the surface to be cleaned to clean the surface to be cleaned. The cleaning element 13 can be a roller brush, but is not limited thereto, and can also be a brush bar, an edge brush, etc., which can be selected and set according to actual conditions, all of which are within the protection scope of the present disclosure.

[0119] The cleaning device 01 can also include a normal-temperature cleaning liquid conveying flow path 2. The normal-temperature cleaning liquid conveying flow path 2 can be configured to convey normal-temperature cleaning liquid to the dispensing element 11. The cleaning liquid can be clean water and / or a decontamination liquid or foam having a decontamination effect, etc. The normal-temperature cleaning liquid can be understood as cleaning liquid that has not been heated. The cleaning device 01 can have a normal-temperature cleaning mode, as shown by the solid arrow in FIG. 1, that is, when cleaning the surface to be cleaned, the normal-temperature cleaning liquid conveying flow path 2 can be used to convey normal-temperature cleaning liquid to the dispensing element 11, and the normal-temperature cleaning liquid can be used in cooperation with the cleaning working part 1 to clean, so as to improve the cleaning effect of the cleaning device 01. Figure 3

[0120] The dispensing element 11 can be in communication with the normal-temperature cleaning liquid conveying flow path 2 to receive the normal-temperature cleaning liquid conveyed by the normal-temperature cleaning liquid conveying flow path 2. The dispensing element 11 can convey the normal-temperature cleaning liquid to the cleaning element 13 to wet the cleaning element 13, so as to improve the cleaning ability of the cleaning element 13, thereby achieving the purpose of improving the cleaning effect of the cleaning device 01. Alternatively, the dispensing element 11 can convey the normal-temperature cleaning liquid to the front of the cleaning element 13 to wet the dirt on the surface to be cleaned in front of the cleaning element 13, so that the dirt on the surface to be cleaned is easily cleaned by the cleaning element 13, thereby also achieving the purpose of improving the cleaning effect of the cleaning device 01.

[0121] It should be noted that the front of the cleaning element 13 described above refers to the front of the cleaning element 13 in the movement direction of the cleaning device 01.

[0122] ​The distribution member 11 can be a water bar, which can have a plurality of water outlets arranged at intervals to deliver the normal-temperature cleaning liquid to the cleaning member 13 or the surface to be cleaned. In this way, the water outlet range of the distribution member 11 can be increased, and the wetting range of the cleaning member 13 or the dirt can be further improved, thereby further improving the cleaning effect of the cleaning device 01. However, the distribution member 11 can not be a water bar, and can be another independent structure capable of delivering water, or the distribution member 11 can be the pipe end opening of the normal-temperature cleaning liquid delivery channel 2, and the present disclosure does not limit the distribution member 11.

[0123] The cleaning device 01 can further include a steam delivery channel. The steam delivery channel can deliver steam to the fluid output member 12. The steam can be steam formed by heating the normal-temperature cleaning liquid, i.e., water vapor and / or decontamination liquid steam. The cleaning device 01 provided by the present disclosure can also have a steam cleaning mode, as shown by the solid arrow in FIG. 1B, i.e., when cleaning the surface to be cleaned, steam can be delivered to the fluid output member 12 by the steam delivery channel, and the steam can be used in combination with the cleaning working part 1 to clean the surface to be cleaned. Since the steam has a high temperature and humidity, the cleaning effect of the cleaning device 01 can be further improved. Figure 4

[0124] The fluid output member 12 can be in communication with the steam delivery channel to receive the steam delivered by the steam delivery channel. The fluid output member 12 can deliver the steam to the cleaning member 13 to wet the cleaning member 13, thereby further improving the cleaning ability of the cleaning member 13, and achieving the purpose of further improving the cleaning effect of the cleaning device 01. Alternatively, the fluid output member 12 can deliver the steam to the surface to be cleaned in front of the cleaning member 13 to heat and wet the dirt on the surface to be cleaned in front of the cleaning member 13, so that the dirt on the surface to be cleaned is more easily cleaned by the cleaning member 13, thereby also achieving the purpose of further improving the cleaning effect of the cleaning device 01.

[0125] Alternatively, the cleaning device 01 can also have a self-cleaning mode. In the self-cleaning mode, the fluid output member 12 can deliver the steam to the cleaning member 13 to wet the cleaning member 13, so as to self-clean the cleaning member 13 and improve the use convenience and service life of the cleaning device 01. In addition, the high-temperature steam can also sterilize and disinfect the cleaning member 13, so as to further improve the self-cleaning effect.

[0126] ​The fluid output 12 can include a steam nozzle 121, which can deliver steam to the cleaning element 13 or in front of the cleaning element 13. The fluid output 12 can have one steam nozzle 121 or multiple steam nozzles 121 arranged at intervals, and steam can be delivered to the cleaning element 13 or in front of the cleaning element 13 through the multiple steam nozzles 121. In this way, the range of steam delivery of the fluid output 12 can be improved, thereby further improving the cleaning effect or self-cleaning effect of the cleaning device 01. However, the fluid output 12 can not include a steam nozzle 121, and can be another independent structure capable of delivering steam, or the fluid output 12 can be a pipe end opening of a steam delivery flow path, and the present disclosure does not limit the same.

[0127] As described above, the cleaning device 01 provided by the present disclosure can freely select a cleaning mode according to cleaning needs, can improve the use range and cleaning effect of the cleaning device 01, and can also reasonably distribute the energy consumption of the cleaning device 01.

[0128] For example, when the dirt on the surface to be cleaned is not stubborn, only the cleaning element 13 can be used for cleaning, so that the cleaning device 01 can achieve a better cleaning effect in a low-energy state.

[0129] When the dirt on the surface to be cleaned is relatively stubborn, the normal-temperature cleaning mode can be switched to, and the normal-temperature cleaning liquid can be used in cooperation with the cleaning element 13 to clean the relatively stubborn dirt, so that the cleaning device 01 can achieve a better cleaning effect in a medium-energy state. Moreover, the normal-temperature cleaning mode is switched only when the dirt is relatively stubborn, so that the time for the cleaning device 01 to be in a medium-energy state can be reduced, thereby achieving the purpose of energy saving.

[0130] When the dirt on the surface to be cleaned is strongly stubborn, the steam cleaning mode can be switched to, and steam can be used in cooperation with the cleaning element 13 to clean the strongly stubborn dirt, so that the cleaning device 01 can achieve a better cleaning effect in a high-energy state. Moreover, the steam cleaning mode is switched only when the dirt is strongly stubborn, so that the time for the cleaning device 01 to be in a high-energy state can be reduced, thereby achieving the purpose of energy saving.

[0131] The steam delivery flow path can be connected to the normal-temperature cleaning liquid delivery flow path 2 to receive the normal-temperature cleaning liquid in the normal-temperature cleaning liquid delivery flow path 2, and the received normal-temperature cleaning liquid can be heated to form steam. The steam delivery flow path can be connected to the normal-temperature cleaning liquid delivery flow path 2 at a first position of the normal-temperature cleaning liquid delivery flow path 2.

[0132] The steam delivery flow path can comprise a heater 5. The heater 5 can be a boiler, but is not limited thereto, and can be another component having a heating function. An input end of the heater 5 can be connected to the normal-temperature cleaning liquid delivery flow path 2 for heating the cleaning liquid. When the steam delivery flow path is connected to the normal-temperature cleaning liquid delivery flow path 2 at the first position of the normal-temperature cleaning liquid delivery flow path 2, the input end of the heater 5 can be connected to the normal-temperature cleaning liquid delivery flow path 2 at the first position of the normal-temperature cleaning liquid delivery flow path 2. An output end of the heater 5 can be in communication with the fluid output member 12 for delivering steam to the fluid output member 12, but is not limited thereto, and can be another device having a heating function. In the normal-temperature cleaning mode, the heater 5 is in an off state. In the steam cleaning mode, as shown by the solid arrow in FIG. 7, the heater 5 is in an on state. Figure 4

[0133] The heater 5 can comprise a heater 5 body and a first filter screen. The first filter screen can be arranged in the heater 5 body and located between the input end and the output end of the heater 5 for filtering water in the heater 5 to avoid impurities blocking the pipeline and the cleaning working part 1, thereby improving the service life of the cleaning device 01. The mesh aperture of the first filter screen can be 1 mm to 3 mm, for example, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc. In this way, the first filter screen can have a good filtering effect while improving the flow capacity of the first filter screen, ensuring that water in the heater 5 can pass through the first filter screen normally, and reducing the probability of the first filter screen being blocked.

[0134] In some embodiments, the cleaning device 01 can further comprise a second filter screen 9 arranged at the output end of the heater 5. The mesh aperture of the second filter screen 9 can be smaller than that of the first filter screen. In this way, the second filter screen 9 can further filter water or steam output from the heater 5 to further remove impurities inside, further reduce the probability of impurities blocking the downstream pipeline and the cleaning working part 1, and further improve the service life of the cleaning device 01.

[0135] The mesh aperture of the second filter screen 9 can be 0.2 mm to 1 mm, for example, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc. In this way, the second filter screen 9 can have a good filtering effect while improving the flow capacity of the second filter screen 9, ensuring that water in the heater 5 can pass through the second filter screen 9 normally.

[0136] ​The filtering area of the second filter screen 9 can be larger than that of the first filter screen, so as to improve the filtering effect of the second filter screen 9 and ensure that the cleaning liquid or steam conveyed to the downstream pipeline and the cleaning working part 1 is free of impurities. In addition, by increasing the filtering area of the second filter screen 9, the probability of clogging of the second filter screen 9 can be reduced.

[0137] The filtering area of the second filter screen 9 can be 500mm 2 to 2000mm 2 , for example: 500mm 2 , 600mm 2 , 700mm 2 , 800mm 2 , 900mm 2 , 1000mm 2 , 1100mm 2 , 1200mm 2 , 1300mm 2 , 1400mm 2 , 1500mm 2 , 1600mm 2 , 1700mm 2 , 1800mm 2 , 1900mm 2 , 2000mm 2 and the like. In this way, the second filter screen 9 can have sufficient filtering area, and the problem of occupying a large internal space of the cleaning device 01 due to the excessively large filtering area of the second filter screen 9 can be avoided, thereby facilitating the miniaturization of the cleaning device 01.

[0138] The normal-temperature cleaning liquid conveying flow path 2 can include a liquid supply tank 21, which can be used to store normal-temperature cleaning liquid and supply normal-temperature cleaning liquid to the normal-temperature cleaning liquid conveying flow path 2.

[0139] The normal-temperature cleaning liquid conveying flow path 2 can include a first liquid pump 22. The first liquid pump 22 can be located on the normal-temperature cleaning liquid conveying flow path 2. The input end of the first liquid pump 22 can be in communication with the liquid supply tank 21 to extract normal-temperature cleaning liquid in the liquid supply tank 21. The output end of the first liquid pump 22 can be used to convey normal-temperature cleaning liquid to the distribution member 11.

[0140] The steam conveying flow path can include a second liquid pump 6. The second liquid pump 6 can be connected to the normal-temperature cleaning liquid conveying flow path 2 at a first position of the normal-temperature cleaning liquid conveying flow path 2. The input end of the second liquid pump 6 can be connected to the normal-temperature cleaning liquid conveying flow path 2 at the first position of the normal-temperature cleaning liquid conveying flow path 2, and the output end of the second liquid pump 6 can be in communication with the input end of the heater 5. By providing the second liquid pump 6, the normal-temperature cleaning liquid in the normal-temperature cleaning liquid conveying flow path 2 can be pumped into the steam conveying flow path.

[0141] In normal temperature cleaning mode, such as Figure 3 As shown by the solid arrows, the first liquid pump 22 can be in the on state, and the second liquid pump 6 can be in the off state. The ambient temperature cleaning liquid delivery path 2 can deliver ambient temperature cleaning liquid to the distribution unit 11. In steam cleaning mode, as... Figure 4 As shown by the solid arrows in the diagram, both the first liquid pump 22 and the second liquid pump 6 can be in the open state. The room temperature cleaning liquid delivery path 2 can deliver room temperature cleaning liquid to the distribution unit 11, and the steam delivery path can deliver steam to the fluid output unit 12.

[0142] In some embodiments, the flow rate of the second liquid pump 6 can be less than the flow rate of the first liquid pump 22. Since the steam conveying path does not require a large amount of cleaning liquid when conveying steam, the above configuration allows for a reasonable allocation of cleaning liquid volume in each path, avoiding waste of cleaning liquid resources and ensuring that the steam conveying path can generate steam more quickly. Furthermore, since the required cleaning liquid volume differs significantly between the steam cleaning mode and the room temperature cleaning mode, this disclosure, by setting the first liquid pump 22 and the second liquid pump 6 in the room temperature cleaning liquid conveying path 2 and the steam conveying path respectively, avoids the sharing of a single liquid pump between the room temperature cleaning liquid conveying path 2 and the steam conveying path. This also avoids the problem of poor pump uniformity during mode switching, ensuring the uniformity of steam or room temperature cleaning liquid output. Simultaneously, setting the first liquid pump 22 and the second liquid pump 6 can improve the uniformity of each liquid pump and reduce the probability of damage to each liquid pump, thereby improving the reliability and service life of the cleaning equipment 01.

[0143] The flow rate range of the first liquid pump 22 can be from 10ml / min to 500ml / min, for example: 10ml / min, 50ml / min, 100ml / min, 150ml / min, 200ml / min, 250ml / min, 300ml / min, 350ml / min, 400ml / min, 450ml / min, 500ml / min, etc. This setting can ensure the delivery volume of room temperature cleaning liquid in room temperature cleaning mode.

[0144] The flow range of the second liquid pump 6 can be 0.5 ml / min to 9 ml / min, for example: 0.5 ml / min, 1 ml / min, 2 ml / min, 3 ml / min, 4 ml / min, 5 ml / min, 6 ml / min, 7 ml / min, 8 ml / min, 9 ml / min, etc. In this way, the amount of cleaning liquid required in the steam cleaning mode can be ensured. This can avoid the problem that the steam is slow and uneven due to too much cleaning liquid in the steam cleaning mode. It can also avoid the problem that the heater 5 is dry burning due to too little cleaning liquid in the steam cleaning mode, thereby avoiding damage to the heater 5. At the same time, it can also avoid the problem that too little steam is formed due to too little cleaning liquid, and can ensure the cleaning effect of the cleaning device 01 in the steam cleaning mode.

[0145] The steam delivery flow path can include a pressure relief valve 7. The pressure relief valve 7 can have a second input end, an output end, and a pressure relief end. The second input end of the pressure relief valve 7 can be in communication with the output end of the second liquid pump 6, the output end of the pressure relief valve 7 can be in communication with the input end of the heater 5, and the pressure relief end of the pressure relief valve 7 can be in communication with the outside of the cleaning device 01, for adjusting the pressure in the steam delivery flow path, to avoid damage to the steam delivery flow path due to excessive liquid pressure in the steam delivery flow path.

[0146] The pressure relief valve 7 can include a spring valve that automatically opens when the internal pressure of the cleaning device 01 pipeline is too high, and automatically closes when the internal pressure of the cleaning device 01 pipeline is normal. In this way, automatic adjustment of the internal pressure of the cleaning device 01 pipeline can be achieved.

[0147] The normal-temperature cleaning liquid delivery flow path 2 can also include a first reversing valve 25, which can be located at a third position of the normal-temperature cleaning liquid delivery flow path 2, and the third position can be located between the first liquid pump 22 and the distribution piece 11. The pressure relief valve 7 can also have a first input end, the input end of the first reversing valve 25 can be in communication with the output end of the first liquid pump 22, the first output end of the first reversing valve 25 can be in communication with the first input end of the pressure relief valve 7, and the second output end of the first reversing valve 25 can be in communication with the distribution piece 11. In this way, the normal-temperature cleaning liquid delivery flow path 2 can be in communication with the pressure relief valve 7, and the pressure in the normal-temperature cleaning liquid delivery flow path 2 can be adjusted by the pressure relief valve 7, to avoid damage to the normal-temperature cleaning liquid delivery flow path 2 due to excessive water pressure in the normal-temperature cleaning liquid delivery flow path 2.

[0148] The cleaning device 01 can also include a stain removal liquid delivery flow path 3. The stain removal liquid delivery flow path 3 can be used to deliver stain removal liquid to the normal-temperature cleaning liquid delivery flow path 2, i.e., the stain removal liquid delivery flow path 3 can access the normal-temperature cleaning liquid delivery flow path 2, to further improve the cleaning effect of the cleaning device 01 on the surface to be cleaned.

[0149] The decontamination liquid conveying flow path 3 can access the normal-temperature cleaning liquid conveying flow path 2 at the second position. That is, the second position can be located downstream of the first position, that is, the first position can be located upstream of the second position, and the water in the normal-temperature cleaning liquid conveying flow path 2 passes through the first position first and then passes through the second position. The decontamination liquid generally has strong corrosiveness, and such arrangement can avoid the situation that the decontamination liquid enters the heater 5, causing the cleaning device 01 to be unable to work normally, thereby improving the use reliability of the cleaning device 01 and improving the use experience of the user.

[0150] The decontamination liquid conveying flow path 3 can include a decontamination liquid supply bin 31 and a third liquid pump 32. The decontamination liquid supply bin 31 can be used to store decontamination liquid. The input end of the third liquid pump 32 can be in communication with the decontamination liquid supply bin 31, and the output end of the third liquid pump 32 can access the normal-temperature cleaning liquid conveying flow path 2. That is, the output end of the third liquid pump 32 can access the normal-temperature cleaning liquid conveying flow path 2 at the second position. The third liquid pump 32 can draw out the decontamination liquid in the decontamination liquid supply bin 31 and convey it to the normal-temperature cleaning liquid conveying flow path 2.

[0151] In some embodiments, the decontamination liquid supply bin 31 can be located in the liquid supply tank 21 to improve the integration of the cleaning device 01. The decontamination liquid addition port of the decontamination liquid supply bin 31 and the normal-temperature cleaning liquid addition port of the liquid supply tank 21 can be different addition ports to facilitate the addition of decontamination liquid and normal-temperature cleaning liquid, respectively.

[0152] The normal-temperature cleaning liquid conveying flow path 2 can further include a first multi-way 23. The first multi-way 23 can be located at the first position of the normal-temperature cleaning liquid conveying flow path 2, and the first multi-way 23 can have multiple ports. The steam conveying flow path can access the normal-temperature cleaning liquid conveying flow path 2 through the first multi-way 23, and specifically, the input end of the heater 5 can access the normal-temperature cleaning liquid conveying flow path 2 through the first multi-way 23. That is, it can be understood that the pipeline between the starting end of the normal-temperature cleaning liquid conveying flow path 2 and the first position can be reused as part of the steam conveying flow path for conveying normal-temperature cleaning liquid to the input end of the heater.

[0153] Further, the liquid supply tank 21, the input end of the first liquid pump 22, and the input end of the second liquid pump 6 can be in communication with different ports of the first multi-way 23, respectively, to divert part of the normal-temperature cleaning liquid in the normal-temperature cleaning liquid conveying flow path 2 to the steam conveying flow path through the first multi-way 23. In this embodiment, the first multi-way 23 can be a three-way, that is, the first multi-way 23 can have three ports, but is not limited thereto, and the first multi-way 23 can have more than three ports.

[0154] The first multi-pass 23 and the first liquid pump 22 can have a first flow resistance, the first multi-pass 23 and the second liquid pump 6 can have a second flow resistance, and the first flow resistance can be greater than the second flow resistance. In this way, the normal-temperature cleaning liquid in the normal-temperature cleaning liquid conveying flow path 2 can be prevented from being excessively conveyed to the first liquid pump 22, that is, the normal-temperature cleaning liquid can be prevented from being excessively occupied by the first liquid pump 22 with a larger flow rate, so that the second liquid pump 6 can also obtain sufficient normal-temperature cleaning liquid, and the steam conveying flow path can obtain sufficient normal-temperature cleaning liquid for forming steam in the steam cleaning mode.

[0155] The pipeline between the first multi-pass 23 and the first liquid pump 22 can have a first length, the pipeline between the second multi-pass 24 and the second liquid pump 6 can have a second length, and the second length can be less than the first length. In this way, the first flow resistance between the first multi-pass 23 and the first liquid pump 22 can be increased, so that the first flow resistance is greater than the second flow resistance.

[0156] The pipeline between the first multi-pass 23 and the first liquid pump 22 can have a first cross-sectional area, the pipeline between the first multi-pass 23 and the second liquid pump 6 can have a second cross-sectional area, and the second cross-sectional area can be greater than the first cross-sectional area. In this way, the normal-temperature cleaning liquid can also be prevented from being excessively occupied by the first liquid pump 22 with a larger flow rate, so that the second liquid pump 6 can also obtain sufficient normal-temperature cleaning liquid.

[0157] A first number of components can be arranged on the pipeline between the first multi-pass 23 and the first liquid pump 22. A second number of components can be arranged on the pipeline between the second multi-pass 24 and the second liquid pump 6. The second number can be less than the first number. In this way, the water can pass through more components on the way from the first multi-pass 23 to the first liquid pump 22, so that the first flow resistance can be increased, and the first flow resistance is greater than the second flow resistance.

[0158] It should be noted that the components described herein can include a multi-pass, a valve body, a liquid pump, and other components with water flow capacity.

[0159] The normal-temperature cleaning liquid conveying flow path 2 can further include a second multi-pass 24. The second multi-pass 24 can be located at a second position of the normal-temperature cleaning liquid conveying flow path 2, that is, the second multi-pass 24 can be arranged on the pipeline between the first multi-pass 23 and the first liquid pump 22. Furthermore, the second multi-pass 24 can have a plurality of ports, and the dirt-removing liquid conveying flow path 3 can access the normal-temperature cleaning liquid conveying flow path 2 through the second multi-pass 24, so as to convey the cleaning liquid in the cleaning conveying flow path to the normal-temperature cleaning liquid conveying flow path 2. Furthermore, the first multi-pass 23, the input end of the first liquid pump 22, and the output end of the third liquid pump 32 can be respectively communicated with different ports of the second multi-pass 24. In the embodiment, the second multi-pass 24 can be a three-way, that is, the second multi-pass 24 can have three ports, but is not limited thereto, and the second multi-pass 24 can have more than four ports.

[0160] In other embodiments, the cleaning fluid delivery path 3 is also connected to the room temperature cleaning fluid delivery path 2 via the first multi-port 23. That is, the output end of the third liquid pump 32 can be connected to the port of the first multi-port 23. With this configuration, only one multi-port needs to be set in the cleaning device 01, which can reduce the manufacturing cost of the cleaning device 01 and save internal space of the cleaning device 01. In this embodiment, the first multi-port 23 can be a four-port, that is, the first multi-port 23 can have four ports, but it is not limited to this, and the first multi-port 23 can also have more than four ports.

[0161] In some embodiments, the cleaning device 01 may further include a hot cleaning fluid delivery path. The hot cleaning fluid delivery path can be used to deliver hot cleaning fluid to the dispensing member 11. The cleaning device 01 may have a heated cleaning mode, such as... Figure 5 As shown by the solid arrow in the diagram, when cleaning the surface to be cleaned, hot cleaning fluid can be delivered to the distribution unit 11 via the hot cleaning fluid delivery path. The hot cleaning fluid is used in conjunction with the cleaning work unit 1 for cleaning. Since the hot cleaning fluid has a higher temperature and humidity, it can further improve the cleaning effect of the cleaning equipment 01 compared to the normal temperature cleaning mode.

[0162] When the surface to be cleaned is stubbornly dirty, the heating cleaning mode can be switched on. This utilizes hot cleaning fluid in conjunction with cleaning component 13 to remove even the most stubborn dirt, allowing the cleaning device 01 to achieve good cleaning results with medium to high energy consumption. Furthermore, switching to heating cleaning mode only when the dirt is particularly stubborn reduces the time the cleaning device 01 operates at medium to high energy consumption, thus achieving energy savings.

[0163] The pipeline from the starting end of the room temperature cleaning liquid delivery path 2 to the third position can be reused as part of the pipeline of the hot cleaning liquid delivery path, used to deliver room temperature cleaning liquid to the input end of the heater 5. The third position can be located between the first liquid pump 22 and the distributor 11. It is understood that the water entering the hot cleaning liquid delivery path does not pass through the second liquid pump 6. Furthermore, when the cleaning equipment 01 has a decontamination liquid delivery path 3, the third position can be located downstream of the access point of the decontamination liquid delivery path 3, allowing the decontamination liquid to enter the hot cleaning liquid delivery path, improving the cleaning effect of the heated cleaning mode. In the heated cleaning mode, the first liquid pump 22 can be in the on state, the second liquid pump 6 can be in the off state, and the decontamination liquid delivery path 3 can deliver decontamination liquid to the hot cleaning liquid delivery path.

[0164] The hot cleaning liquid delivery flow path can include the heater 5 described above, that is, the hot cleaning liquid delivery flow path and the steam delivery flow path can share one heater 5, so as to reduce the number of heaters 5, improve the integration of the cleaning device 01, and reduce the manufacturing cost of the cleaning device 01. When the heating cleaning mode is started, the heater 5 can be turned on.

[0165] The normal-temperature cleaning liquid delivery flow path 2 can further include a first reversing valve 25. The first reversing valve 25 can be located at a third position, the input end of the first reversing valve 25 can be in communication with the output end of the first liquid pump 22, the first output end of the first reversing valve 25 can be in communication with the input end of the heater 5, and the second output end of the first reversing valve 25 can be in communication with the distribution member 11. When the heating cleaning mode is started, the first reversing valve 25 can be in communication with the input end of the heater 5, so that the normal-temperature cleaning liquid delivery flow path 2 delivers the normal-temperature cleaning liquid into the heater 5 through the third position. When the normal-temperature cleaning mode is started, the first reversing valve 25 can be in communication with the distribution member 11, so that the normal-temperature cleaning liquid delivery flow path 2 directly delivers the normal-temperature cleaning liquid to the distribution member 11.

[0166] The output end of the heater 5 can be connected to the normal-temperature cleaning liquid delivery flow path 2 at a fourth position of the normal-temperature cleaning liquid delivery flow path 2, that is, the pipeline between the fourth position and the end of the normal-temperature cleaning liquid delivery flow path 2 can be reused as part of the hot cleaning liquid delivery flow path, for delivering the hot cleaning liquid heated by the heater 5 to the distribution member 11. The fourth position can be located between the third position and the distribution member 11, so that the water heated by the heater 5 is delivered to the distribution member 11 through the fourth position via the normal-temperature cleaning liquid delivery flow path 2, and the hot cleaning liquid is delivered to the cleaning member 13 or in front of the cleaning member 13 via the distribution member 11.

[0167] The normal-temperature cleaning liquid delivery flow path 2 can further include a third multi-way valve 26. The third multi-way valve 26 can be located at the fourth position, and the third multi-way valve 26 can have multiple ports. The second output end of the first reversing valve 25, the output end of the heater 5, and the distribution member 11 can be in communication with different ports of the third multi-way valve 26, respectively. By arranging the third multi-way valve 26, the normal-temperature cleaning liquid delivery flow path 2 and the hot cleaning liquid delivery flow path can be integrated, so that when the normal-temperature cleaning mode is started, the normal-temperature cleaning liquid can be directly delivered to the distribution member 11 via the third multi-way valve 26, and when the heating cleaning mode is started, the normal-temperature cleaning liquid can be heated by the heater 5 and delivered to the distribution member 11 via the third multi-way valve 26. In this embodiment, the third multi-way valve 26 can be a three-way valve, that is, the third multi-way valve 26 can have three ports, but is not limited thereto, and the third multi-way valve 26 can have multiple ports.

[0168] The hot cleaning liquid delivery flow path can further comprise a fourth multi-way 8. The fourth multi-way 8 can have a plurality of ports, the output end of the second liquid pump 6, the first output end of the first reversing valve 25, and the input end of the heater 5 can be respectively communicated with different ports of the fourth multi-way 8. By providing the fourth multi-way 8, the steam cleaning flow path and the hot cleaning liquid delivery flow path can be integrated, so that in the steam cleaning mode and the self-cleaning mode, the normal-temperature cleaning liquid can enter the heater 5 through the second liquid pump 6 and the fourth multi-way 8; in the heated cleaning mode, the normal-temperature cleaning liquid can directly enter the heater 5 through the first reversing valve 25 and the fourth multi-way 8. In the embodiment, the fourth multi-way 8 can be a three-way, that is, the fourth multi-way 8 can have three ports, but is not limited to this, the fourth multi-way 8 can also have a plurality of ports.

[0169] Further, the first output end of the first reversing valve 25 can be communicated with the first output end of the pressure relief valve 7, so that when the pressure of the normal-temperature cleaning liquid delivery flow path 2 is too high, the normal-temperature cleaning liquid can be delivered to the pressure relief valve 7 to adjust the pressure of the normal-temperature cleaning liquid delivery flow path 2. And, in this way, the normal-temperature cleaning liquid can be delivered into the heater 5 through the first pressure relief valve 7.

[0170] In some embodiments, the fourth multi-way 8 can be reused as the pressure relief valve 7, that is, the valve body can integrate the functions of the fourth multi-way 8 and the pressure relief valve 7. In this way, the manufacturing mold can be saved, and the manufacturing cost of the cleaning device 01 can be reduced. And, the number of components of the cleaning device 01 can be reduced, and the internal space of the cleaning device 01 can be saved.

[0171] In some embodiments, the cleaning device 01 can further comprise a descaling cleaning flow path 4. The descaling cleaning flow path 4 can comprise the above-mentioned heater 5. That is, the descaling cleaning flow path 4 can share the heater 5 with the steam delivery flow path and / or the hot cleaning liquid delivery flow path. The descaling cleaning flow path 4 can further comprise a second reversing valve 10. The input end of the second reversing valve 10 can be communicated with the heater 5, the first output end of the second reversing valve 10 can be communicated with the fluid output 12, and the second output end of the second reversing valve 10 can be communicated to the outside of the cleaning device 01.

[0172] The cleaning device 01 can further have a descaling cleaning mode, as shown by the solid arrows in Figure 6 and Figure 7 In the descaling cleaning mode, the second reversing valve 10 can be communicated with the outside of the cleaning device 01 to discharge the scale to the outside of the cleaning device 01 through the second reversing valve 10.

[0173] In some embodiments, the heater 5 can be in the off state when in the descaling cleaning mode. A descaling agent can be added into the descaling cleaning flow path 4 so as to enter the heater 5 to descale the heater 5, and the descaled descaling agent and / or scale can be discharged to the outside of the cleaning apparatus 01 via the second reversing valve 10. Further, by discharging the descaled descaling agent to the outside of the cleaning apparatus 01 via the second reversing valve 10, the descaled descaling agent can be prevented from entering the fluid output 12 to block the fluid output 12.

[0174] The descaling cleaning flow path 4 can be communicated with the first liquid pump 22, i.e., the descaling cleaning flow path 4 and the normal-temperature cleaning liquid delivery flow path 2 can share the first liquid pump 22. In this way, the descaling agent can be delivered by the first liquid pump 22, the first liquid pump 22 can also be descaled and maintained, and the descaling effect of the descaling agent on the first liquid pump 22 and the heater 5 can be improved.

[0175] In the descaling cleaning mode, the descaling agent can be added into the descaling cleaning flow path 4, the first liquid pump 22 can be in the on state, the second liquid pump 6 and the heater 5 can be in the off state, the first reversing valve 25 can be communicated with the heater 5, and the second reversing valve 10 can be communicated with the outside of the cleaning apparatus 01 so as to make the descaling agent enter the heater 5.

In the heated cleaning mode, the second reversing valve 10 can be communicated with the dispensing member 11 so as to deliver heated cleaning liquid to the dispensing member 11.

[0177] In some embodiments, the descaled descaling agent can be discharged to the cleaning member 13 via the second reversing valve 10. Further, the second output end of the second reversing valve 10 can be communicated with the dispensing member 11, the descaled descaling agent can be delivered to the dispensing member 11 via the second reversing valve 10, and delivered to the outside of the cleaning apparatus 01 by the dispensing member 11. For example, the descaled descaling agent can be delivered to the dispensing member 11 via the second reversing valve 10, and delivered to the cleaning member 13 by the dispensing member 11.

[0178] In some embodiments, the pipeline between the starting end of the normal-temperature cleaning liquid delivery flow path 2 and the fifth position can be reused as part of the descaling cleaning flow path for delivering the descaling agent into the heater 5, that is, the input end of the heater 5 can be connected to the normal-temperature cleaning liquid delivery flow path 2 at the fifth position of the normal-temperature cleaning liquid delivery flow path 2. The first switching valve 25 can be located at the fifth position, and the input end of the heater 5 can be in communication with the first output end of the first switching valve 25. The fifth position can be located between the first liquid pump 22 and the distribution member 11, so that the descaled descaling agent is delivered through the fifth position to the distribution member 11 via the normal-temperature cleaning liquid delivery flow path 2, and is delivered by the distribution member 11 to the cleaning member 13 or in front of the cleaning member 13, so as to be discharged to the outside of the cleaning device 01.

[0179] The fifth position and the third position can be the same, and the descaling cleaning flow path 4 and the hot cleaning liquid delivery flow path can be the same. That is, the descaling cleaning flow path 4 and the hot cleaning liquid delivery flow path can share all components. In this way, the integration of the descaling cleaning flow path 4 and the hot cleaning liquid delivery flow path can be improved, and the integration of the cleaning device 01 can be further improved, and the setting of redundant components can be reduced.

[0180] In the present embodiment, the descaling cleaning flow path 4 and the hot cleaning liquid delivery flow path can share the second switching valve 10, and the second input end of the second switching valve 10 can be in communication with the fourth multi-way 8, so as to deliver the hot cleaning liquid or the descaled descaling agent to the distribution member 11 through the fourth multi-way 8.

[0181] In some embodiments, the descaling agent can be manually added to the descaling cleaning flow path 4. Further, the descaling agent can be manually added to the liquid supply tank 21, so as to be delivered to the descaling cleaning flow path through the normal-temperature cleaning liquid delivery flow path 2.

[0182] In another embodiment, as shown in Figure 2 and Figure 7 The descaling cleaning flow path 4 can include a descaling agent supply bin 41 and a fourth liquid pump 42, the descaling agent supply bin 41 can be used to store the descaling agent, the input end of the fourth liquid pump 42 can be in communication with the descaling agent supply bin 41, and the output end of the fourth liquid pump 42 can be connected to the heater 5.

[0183] In some embodiments, the descaling agent supply bin 41 can be located in the liquid supply tank 21, so as to improve the integration of the cleaning device 01. The descaling agent addition port of the descaling agent supply bin 41, the cleaning agent addition port, and the normal-temperature cleaning liquid addition port of the liquid supply tank 21 can be different addition ports, so as to facilitate the addition of the descaling agent and the normal-temperature cleaning liquid, respectively.

[0184] In some embodiments, the heater 5 can be used to heat the cleaning liquid and deliver the hot cleaning liquid to the fluid output member 12, so that the hot cleaning liquid is delivered to the front of the cleaning member 13 through the fluid output member 12 to clean the surface in cooperation with the cleaning member 13, thereby improving the cleaning effect of the cleaning device 01. The cleaning device 01 can have a strong cleaning mode, such as Figure 7 In the strong cleaning mode, the hot cleaning liquid can be delivered to the surface to be cleaned through the fluid output member 12 for cleaning heavy oil stains or dirt with high strength and stubbornness, as indicated by the solid arrow in the line. In the strong cleaning mode, the heater 5 can be turned on to heat the cleaning liquid and deliver the hot cleaning liquid to the fluid output member 12, so that the hot cleaning liquid is delivered to the front of the cleaning member 13 through the fluid output member 12.

[0185] When the dirt on the surface to be cleaned has heavy oil stains or dirt with high strength and stubbornness, the strong cleaning mode can be switched to, so that the cleaning device 01 can achieve better cleaning effect in a high energy consumption state. And only when the dirt has heavy oil stains or dirt with high strength and stubbornness, the strong cleaning mode is switched to, which can reduce the time of the cleaning device 01 in the high energy consumption state, so as to achieve the purpose of energy saving.

[0186] In some embodiments, the cleaning device 01 can include a strong cleaning flow path. The strong cleaning flow path can include a third heat exchange valve and a heater 5. The heater 5 can be the heater 5 described above, that is, the strong cleaning flow path can share the heater 5 with the steam cleaning flow path, the heated cleaning flow path, and the descaling cleaning flow path 4, so as to further improve the integration of the cleaning device 01.

[0187] The input end of the third heat exchange valve can be in communication with the output end of the heater 5, the first output end of the third reversing valve 14 can be in communication with the fluid output member 12, and the second output end of the third reversing valve 14 can be in communication with the distribution member 11. In the strong cleaning mode, the heater 5 can be in an open state, and the third reversing valve 14 can be in communication with the fluid output member 12 to deliver the hot cleaning liquid to the fluid output member 12. In the heated cleaning mode, the third reversing valve 14 can be in communication with the distribution member 11 to deliver the hot cleaning liquid to the distribution member 11.

[0188] The strong cleaning flow path can be in communication with a first liquid pump 22, so that the first liquid pump 22 is used to deliver the normal temperature cleaning liquid to the heater 5, which can increase the amount of normal temperature cleaning liquid entering the strong cleaning flow path and further improve the cleaning effect of the strong cleaning flow path.

[0189] The pipeline from the starting end of the room temperature cleaning fluid delivery path 2 to the sixth position can be reused as part of the pipeline for the powerful cleaning path, used to deliver room temperature cleaning fluid to the input end of the heater 5. That is, the input end of the heater 5 can be connected to the room temperature cleaning fluid delivery path 2 at the sixth position. The first reversing valve 25 can be located at the sixth position, and the input end of the heater 5 can be connected to the first output end of the first reversing valve 25. The sixth position can be located between the first liquid pump 22 and the distribution component 11. It is understood that the water entering the powerful cleaning path does not pass through the second liquid pump 6. Furthermore, when the cleaning equipment 01 has a decontamination fluid delivery path 3, the sixth position can be located downstream of the access position of the decontamination fluid delivery path 3, so that the decontamination fluid can enter the powerful cleaning path, improving the cleaning effect of the powerful cleaning mode. In the powerful cleaning mode, the first liquid pump 22 can be in the open state, the second liquid pump 6 can be in the closed state, and the decontamination fluid delivery path 3 can deliver decontamination fluid to the powerful cleaning path.

[0190] In some embodiments, the sixth position and the third position can be the same, the third reversing valve 14 and the second reversing valve 10 can be the same reversing valve, and the powerful cleaning flow path can be the same as part of the hot cleaning fluid delivery flow path. That is, the powerful cleaning flow path and the hot cleaning fluid delivery flow path can share some components, such as the heater 5 and the second reversing valve 10. This arrangement can improve the integration and consolidation of the powerful cleaning flow path and the hot cleaning fluid delivery flow path, further improve the integration of the cleaning equipment 01, and reduce the setting of redundant components.

[0191] In some embodiments, the cleaning device 01 may further include a self-cleaning flow path. The self-cleaning flow path may include the second liquid pump 6 and the heater 5 described above. In self-cleaning mode, as... Figure 8 As indicated by the solid arrows, the second liquid pump 6 and heater 5 are in the on state to heat the cleaning liquid to generate steam, and then deliver the steam to the distribution unit 11. This configuration integrates the self-cleaning flow path and the steam cleaning flow path, further improving the integration of the cleaning equipment 01 and reducing the number of unnecessary components.

[0192] The self-cleaning flow path may further include a fourth directional valve 15. The input end of the fourth directional valve 15 can be connected to the output end of the heater 5, the first output end of the fourth directional valve 15 can be connected to the fluid output component 12, and the second output end of the fourth directional valve 15 can be connected to the distribution component 11. In self-cleaning mode, the first liquid pump 22 can be in a closed state, and the fourth directional valve 15 can be connected to the distribution component 11 to deliver steam to the distribution component 11, and then to the cleaning component 13 via the distribution component 11.

[0193] In some embodiments, the fourth directional valve 15 and the second directional valve 10 can be the same directional valve. In this way, the integration of the cleaning device 01 can be further improved, and the setting of redundant components can be reduced. In addition, the self-cleaning flow path and the partial steam delivery flow path can be the same, i.e., the self-cleaning flow path and the steam delivery flow path can share some components, such as the second liquid pump 6, the heater 5, and the second directional valve 10, etc.

[0194] In some embodiments, the third position, the fifth position, and the sixth position described above can all be the same, and the second directional valve 10, the third directional valve 14, and the fourth directional valve 15 can all be the same, but are not limited thereto.

[0195] In some embodiments, as shown in Figures 1 to 9 The normal-temperature cleaning liquid delivery flow path 2 can also include a flow detector 27. The flow detector 27 can be a flow sensor or the like. The flow detector 27 can be located between the liquid supply tank 21 and the first position, for detecting the amount of water entering the normal-temperature cleaning liquid delivery flow path 2 from the liquid supply tank 21. In addition, by detecting whether there is water in the normal-temperature cleaning liquid delivery flow path 2, it can be determined whether to turn on the heater 5, so as to prevent the heater 5 from being dry-burned without water, and reduce the probability of damage to the heater 5.

[0196] In some embodiments, a preset time can be set, and the heater 5 can be turned on only when the flow detector 27 detects that there is water in the normal-temperature cleaning liquid delivery flow path 2 within the preset time. The preset time can be 3 seconds, but is not limited thereto.

[0197] In some embodiments, a control method of the cleaning device 01 is provided. As shown in Figures 1 to 15 The control method of the cleaning device 01 can be used to control the cleaning device 01 described above.

[0198] It should be noted that the specific structure and beneficial effects of the cleaning device 01 have been described in detail in the previous embodiment of the present disclosure, so in this embodiment, the specific structure and beneficial effects of the cleaning device 01 will not be described again, and reference can be made to the specific description in the previous embodiment, which is within the protection scope of the present disclosure.

[0202] The control method of the cleaning device 01 can further include:

[0203] In step S30, the cleaning mode further includes a steam cleaning instruction, and in response to the steam cleaning instruction, the control of the cleaning device 01 enters a steam cleaning mode to heat the cleaning liquid in the steam delivery flow path and deliver steam to the fluid output member 12.

[0204] As shown in Figures 1 to 4 The control method of the cleaning device 01 provided by the present disclosure can use the dry cleaning working part 1 to clean when controlling the cleaning device 01 to clean the surface to be cleaned; or the cleaning device 01 can be controlled to enter the normal temperature cleaning mode, that is, when cleaning the surface to be cleaned, the normal temperature cleaning liquid delivery flow path 2 can be used to deliver normal temperature cleaning liquid to the distribution member 11, and the normal temperature cleaning liquid can be used to clean with the cleaning working part 1 to improve the cleaning effect of the cleaning device 01; or the cleaning device 01 can be controlled to enter the steam cleaning mode, that is, when cleaning the surface to be cleaned, the steam delivery flow path can be used to deliver steam to the fluid output member 12, and the steam can be used to clean with the cleaning working part 1. Since the steam has high temperature and humidity, the cleaning effect of the cleaning device 01 can be further improved.

The first liquid pump 22 and the second liquid pump 6 can be turned on, and the first reversing valve 25 can be connected to the distributor 11, opening the cleaning fluid delivery path 3. This allows the cleaning fluid and a portion of the room-temperature cleaning fluid to be directly delivered to the distributor 11 through the room-temperature cleaning fluid delivery path 2, while another portion of the room-temperature cleaning fluid enters the steam delivery path via the first multi-port 23. The cleaning fluid can be heated by the heater 5 to form steam, which is then delivered to the fluid output device 12 through the steam delivery path.
