[0150] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0151] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0152] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0153] As shown in Figures 1 to 13, some embodiments provide a cleaning device 01. This cleaning device 01 can be a floor scrubber, a robotic vacuum cleaner, a vacuum and mop combo, etc., and this disclosure does not impose specific limitations on it. The cleaning device 01 has a good cleaning effect.

[0154] The cleaning device 01 may include a cleaning work unit 1. The cleaning work unit 1 can be used to clean the surface to be cleaned. The cleaning work unit 1 may include a cleaning component 13, a dispensing component 11, and a fluid output component 12.

[0155] The cleaning component 13 can contact the surface to be cleaned to clean the surface. The cleaning component 13 can be a roller brush, but is not limited to this. The cleaning component 13 can also be a brush strip, side brush, etc., and can be selected and set according to the actual situation. All of these are within the protection scope of this disclosure.

[0156] The cleaning device 01 may further include: a room temperature cleaning liquid delivery path 2. The room temperature cleaning liquid delivery path 2 can be configured to deliver room temperature cleaning liquid to the distribution unit 11. The cleaning liquid can be clean water and / or a detergency liquid or foam, etc. Room temperature cleaning liquid can be understood as a cleaning liquid that has not been heated. The cleaning device 01 can have a room temperature cleaning mode, as shown by the solid arrow in Figure 3, that is: when cleaning the surface to be cleaned, the room temperature cleaning liquid delivery path 2 can be used to deliver room temperature cleaning liquid to the distribution unit 11, and the room temperature cleaning liquid can be used in conjunction with the cleaning work unit 1 to perform cleaning, thereby improving the cleaning effect of the cleaning device 01.

[0157] The distribution component 11 can be connected to the room temperature cleaning liquid delivery path 2 to receive the room temperature cleaning liquid delivered by the room temperature cleaning liquid delivery path 2. The distribution component 11 can deliver the room temperature cleaning liquid to the cleaning component 13 to wet the cleaning component 13, thereby improving the cleaning ability of the cleaning component 13 and thus improving the cleaning effect of the cleaning equipment 01. Alternatively, the distribution component 11 can deliver the room temperature cleaning liquid to the front of the cleaning component 13 to wet the dirt on the surface to be cleaned in front of the cleaning component 13, making the dirt on the surface to be cleaned easier to be cleaned by the cleaning component 13, thereby also improving the cleaning effect of the cleaning equipment 01.

[0158] It should be noted that the "front" of the cleaning component 13 mentioned above refers to the front of the cleaning component 13 in the direction of movement of the cleaning device 01.

[0159] The distribution component 11 can be a water strip, which may have multiple spaced-apart water outlets to deliver room-temperature cleaning fluid to the cleaning component 13 or the surface to be cleaned. This configuration increases the water outlet range of the distribution component 11, further increasing the wetting range of the cleaning component 13 or the dirt, thereby further improving the cleaning effect of the cleaning equipment 01. However, it is not limited to this; the distribution component 11 may not be a water strip, but may be other independent structural components capable of discharging water, or it may be the end opening of the pipe in the room-temperature cleaning fluid delivery path 2, etc. This disclosure does not limit this.

[0160] The cleaning device 01 may further include a steam delivery path. The steam delivery path can deliver steam to the fluid output component 12. The steam can be steam formed by heating a room-temperature cleaning liquid, i.e., the steam can be water vapor and / or detergent vapor, etc. The cleaning device 01 provided in this disclosure may also have a steam cleaning mode, as shown by the solid arrow in Figure 4. That is, when cleaning the surface to be cleaned, steam can be delivered to the fluid output component 12 using the steam delivery path, and the steam can be used in conjunction with the cleaning workpiece 1 for cleaning. Because the steam has a high temperature and humidity, the cleaning effect of the cleaning device 01 can be further improved.

[0161] The fluid output component 12 can be connected to the steam conveying path to receive steam conveyed by the steam conveying path. The fluid output component 12 can deliver steam to the cleaning component 13 to moisten the cleaning component 13, thereby further improving the cleaning ability of the cleaning component 13 and thus achieving the purpose of further improving the cleaning effect of the cleaning equipment 01. Alternatively, the fluid output component 12 can deliver steam to the surface to be cleaned in front of the cleaning component 13 to heat and moisten the dirt on the surface to be cleaned at high temperature, making the dirt on the surface to be cleaned easier to be cleaned by the cleaning component 13, thereby also achieving the purpose of further improving the cleaning effect of the cleaning equipment 01.

[0162] Alternatively, the cleaning device 01 can also have a self-cleaning mode. In self-cleaning mode, the fluid output component 12 can deliver steam to the cleaning component 13 to moisten it, thereby performing self-cleaning and improving the ease of use and service life of the cleaning device 01. Furthermore, the high-temperature steam can also sterilize and disinfect the cleaning component 13, further enhancing the self-cleaning effect.

[0163] The fluid output component 12 may include a steam nozzle 121, which can deliver steam to the cleaning component 13 or in front of the cleaning component 13. The fluid output component 12 may have one steam nozzle 121 or multiple steam nozzles 121 spaced apart, and steam can be delivered to the cleaning component 13 or in front of the cleaning component 13 through multiple steam nozzles 121. This configuration can increase the range of steam delivery by the fluid output component 12, thereby further improving the cleaning effect or self-cleaning effect of the cleaning device 01. However, it is not limited to this; the fluid output component 12 may also not include a steam nozzle 121, and it may also be other independent structural components capable of delivering steam, or the fluid output component 12 may also be the end opening of a pipeline for steam delivery, etc., and this disclosure does not limit it in this way.

[0164] As can be seen from the above, the cleaning equipment 01 provided in this disclosure can freely select the cleaning mode according to the cleaning needs, which can improve the scope of use and cleaning effect of the cleaning equipment 01, and can also reasonably allocate the energy consumption of the cleaning equipment 01.

[0165] For example, when the dirt on the surface to be cleaned is not stubborn, it can be cleaned using only the cleaning component 13, allowing the cleaning device 01 to achieve a good cleaning effect with low energy consumption.

[0166] When the surface to be cleaned is stubbornly dirty, the system can be switched to room temperature cleaning mode. Room temperature cleaning solution, in conjunction with cleaning component 13, can effectively remove stubborn dirt, allowing the cleaning device 01 to achieve good cleaning results with moderate energy consumption. Furthermore, switching to room temperature cleaning mode only when the dirt is stubborn reduces the time the cleaning device 01 operates in moderate energy consumption mode, thus achieving energy savings.

[0167] When the dirt on the surface to be cleaned is highly stubborn, the steam cleaning mode can be switched on. Steam, in conjunction with the cleaning component 13, can effectively remove even the most stubborn dirt, allowing the cleaning device 01 to achieve a better cleaning effect despite high energy consumption. Furthermore, switching to steam cleaning mode only when the dirt is highly stubborn reduces the time the cleaning device 01 operates in a high-energy-consumption state, thus achieving energy savings.

[0168] The steam conveying path can be connected to the ambient temperature cleaning liquid conveying path 2 to receive the ambient temperature cleaning liquid in the ambient temperature cleaning liquid conveying path 2 and heat the received ambient temperature cleaning liquid to form steam. The steam conveying path can be connected to the ambient temperature cleaning liquid conveying path 2 at a first position.

[0169] The steam delivery path may include a heater 5. The heater 5 can be a boiler, but is not limited to this; it can also be other components with heating capabilities. The input end of the heater 5 can be connected to the ambient temperature cleaning liquid delivery path 2 for heating the cleaning liquid. When the steam delivery path is connected to the ambient temperature cleaning liquid delivery path 2 at its first position, the input end of the heater 5 can also be connected to the ambient temperature cleaning liquid delivery path 2 at its first position. The output end of the heater 5 can be connected to the fluid output component 12 for supplying steam to the fluid output component 12; however, it is not limited to this, and the heater 5 can also be other devices with heating functions. In ambient temperature cleaning mode, the heater 5 is in the off state. In steam cleaning mode, as shown by the solid arrow in Figure 4, the heater 5 is in the on state.

[0170] The heater 5 may include a heater body and a first filter. The first filter may be disposed within the heater body and located between the input and output ends of the heater 5 to filter the water within the heater 5, preventing impurities from clogging the pipes and the cleaning unit 1, thereby extending the service life of the cleaning equipment 01. The mesh size of the first filter may be 1mm to 3mm, for example: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. This configuration ensures good filtration while improving the flow capacity of the first filter, guaranteeing that water within the heater 5 can pass through the first filter normally, and reducing the probability of clogging.

[0171] In some embodiments, the cleaning device 01 may further include a second filter 9, which may be disposed at the output end of the heater 5. The mesh size of the second filter 9 may be smaller than that of the first filter. This arrangement allows the second filter 9 to further filter the water or steam output from the heater 5, further removing internal impurities, further reducing the probability of impurities clogging downstream pipes and the cleaning workpiece 1, and further improving the service life of the cleaning device 01.

[0172] The pore size of the second filter screen 9 can be from 0.2mm to 1mm, for example: 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc. This setting ensures that the second filter screen 9 has a good filtration effect and improves its flow capacity, ensuring that the water in the heater 5 can pass through the second filter screen 9 normally.

[0173] The filtration area of ​​the second filter screen 9 can be larger than that of the first filter screen to improve the filtration effect of the second filter screen 9 and ensure that the cleaning liquid or steam delivered to the downstream pipeline and cleaning work section 1 is free of impurities. Furthermore, by increasing the filtration area of ​​the second filter screen 9, the probability of clogging can be reduced.

[0174] The second filter 9 has a filtration area of ​​500 mm². 2 Up 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 21600mm 2 1700mm 2 1800mm 2 1900mm 2 2000mm 2 This configuration ensures that the second filter 9 has a sufficient filtration area and avoids the problem of the second filter 9 occupying too much internal space in the cleaning device 01 due to its excessive filtration area, thus facilitating the miniaturization of the cleaning device 01.

[0175] The room temperature cleaning fluid delivery path 2 may include: a liquid supply tank 21, which can be used to store room temperature cleaning fluid and supply room temperature cleaning fluid to the room temperature cleaning fluid delivery path 2.

[0176] The room temperature cleaning fluid delivery path 2 may include a first liquid pump 22. The first liquid pump 22 may be located on the room temperature cleaning fluid delivery path 2. The input end of the first liquid pump 22 may be connected to the supply tank 21 to draw room temperature cleaning fluid from the supply tank 21. The output end of the first liquid pump 22 may be used to deliver room temperature cleaning fluid to the distribution unit 11.

[0177] The steam delivery path may include a second liquid pump 6. The second liquid pump 6 can be connected to the ambient temperature cleaning liquid delivery path 2 at a first position. The input end of the second liquid pump 6 can be connected to the ambient temperature cleaning liquid delivery path 2 at the first position, and the output end of the second liquid pump 6 can be connected to the input end of the heater 5. By setting the second liquid pump 6, the ambient temperature cleaning liquid in the ambient temperature cleaning liquid delivery path 2 can be pumped into the steam delivery path.

[0178] In the ambient temperature cleaning mode, as shown by the solid arrow in Figure 3, the first liquid pump 22 can be turned on, and the second liquid pump 6 can be turned off. The ambient temperature cleaning liquid delivery path 2 can deliver ambient temperature cleaning liquid to the distribution unit 11. In the steam cleaning mode, as shown by the solid arrow in Figure 4, both the first liquid pump 22 and the second liquid pump 6 can be turned on. The ambient temperature cleaning liquid delivery path 2 can deliver ambient temperature cleaning liquid to the distribution unit 11, and the steam delivery path can deliver steam to the fluid output unit 12.

[0179] 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.

[0180] 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.

[0181] The flow rate of the second liquid pump 6 can range from 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. This setting ensures the required amount of cleaning liquid during steam cleaning mode. It avoids the problem of slow and uneven steam formation due to excessive cleaning liquid volume in steam cleaning mode. It also avoids the problem of dry burning of the heater 5 due to insufficient cleaning liquid volume in steam cleaning mode, thus preventing damage to the heater 5. Simultaneously, it avoids the problem of insufficient steam formation due to insufficient cleaning liquid volume, ensuring the cleaning effect of the cleaning equipment 01 in steam cleaning mode.

[0182] The steam delivery path may include a pressure relief valve 7. The pressure relief valve 7 may have a second input terminal, an output terminal, and a pressure relief terminal. The second input terminal of the pressure relief valve 7 may be connected to the output terminal of the second liquid pump 6, the output terminal of the pressure relief valve 7 may be connected to the input terminal of the heater 5, and the pressure relief terminal of the pressure relief valve 7 may be connected to the outside of the cleaning equipment 01 to regulate the pressure within the steam delivery path and prevent damage to the steam delivery path due to excessive liquid pressure.

[0183] The pressure relief valve 7 may include a spring valve. When the internal pressure of the cleaning equipment 01 pipeline is too high, the spring valve will automatically open, and when the internal pressure of the cleaning equipment 01 pipeline is normal, the valve will automatically close. This enables automatic regulation of the internal pressure of the cleaning equipment 01 pipeline.

[0184] The ambient temperature cleaning fluid delivery path 2 may further include: a first reversing valve 25, which may be located at a third position within the ambient temperature cleaning fluid delivery path 2, between the first pump 22 and the distributor 11. The pressure relief valve 7 may also have a first input terminal, which may be connected to the output terminal of the first pump 22, and its first output terminal may be connected to the first input terminal of the pressure relief valve 7. The second output terminal of the first reversing valve 25 may be connected to the distributor 11. This allows the ambient temperature cleaning fluid delivery path 2 to be connected to the pressure relief valve 7, enabling the pressure relief valve 7 to regulate the pressure within the ambient temperature cleaning fluid delivery path 2 and prevent damage to the ambient temperature cleaning fluid delivery path 2 due to excessive water pressure.

[0185] The cleaning equipment 01 may also include: a decontamination liquid delivery path 3. The decontamination liquid delivery path 3 can be used to deliver decontamination liquid to the room temperature cleaning liquid delivery path 2, that is: the decontamination liquid delivery path 3 can be connected to the room temperature cleaning liquid delivery path 2 to further improve the cleaning effect of the cleaning equipment 01 on the surface to be cleaned.

[0186] The cleaning solution delivery path 3 can be connected to the ambient temperature cleaning solution delivery path 2 at a second location. That is, the second location can be downstream of the first location, or the first location can be upstream of the second location. Water in the ambient temperature cleaning solution delivery path 2 first passes through the first location and then through the second location. Cleaning solutions are typically highly corrosive; this arrangement prevents cleaning solution from entering the heater 5 and causing the cleaning equipment 01 to malfunction, thereby improving the reliability of the cleaning equipment 01 and enhancing the user experience.

[0187] The detergent delivery path 3 may include a detergent supply tank 31 and a third pump 32. The detergent supply tank 31 can be used to store detergent. The input end of the third pump 32 can be connected to the detergent supply tank 31, and the output end of the third pump 32 can be connected to the ambient temperature cleaning liquid delivery path 2. That is, the output end of the third pump 32 can be connected to the ambient temperature cleaning liquid delivery path 2 at a second location. The third pump 32 can extract detergent from the detergent supply tank 31 and deliver it to the ambient temperature cleaning liquid delivery path 2.

[0188] In some embodiments, the cleaning solution supply chamber 31 may be located inside the liquid supply tank 21 to improve the integration of the cleaning equipment 01. The cleaning solution filling port of the cleaning solution supply chamber 31 and the room temperature cleaning solution filling port of the liquid supply tank 21 may be different filling ports to facilitate the addition of cleaning solution and room temperature cleaning solution respectively.

[0189] The ambient temperature cleaning fluid delivery path 2 may further include a first multi-port 23. The first multi-port 23 may be located at a first position in the ambient temperature cleaning fluid delivery path 2, and may have multiple ports. A steam delivery path can be connected to the ambient temperature cleaning fluid delivery path 2 via the first multi-port 23. Specifically, the input end of the heater 5 can be connected to the ambient temperature cleaning fluid delivery path 2 via the first multi-port 23. That is, it can be understood that the pipeline from the starting end of the ambient temperature cleaning fluid delivery path 2 to the first position can be reused as part of the pipeline of the steam delivery path for supplying ambient temperature cleaning fluid to the input end of the heater.

[0190] Furthermore, the input terminals of the liquid supply tank 21, the first liquid pump 22, and the second liquid pump 6 can be connected to different ports of the first multi-port 23, respectively, so as to divert a portion of the room temperature cleaning liquid in the room temperature cleaning liquid delivery path 2 to the steam delivery path through the first multi-port 23. In this embodiment, the first multi-port 23 can be a three-way valve, that is, the first multi-port 23 can have three ports, but it is not limited to this, and the first multi-port 23 can also have more than three ports.

[0191] There can be a first flow resistance between the first multi-port 23 and the first liquid pump 22, and there can be a second flow resistance between the first multi-port 23 and the second liquid pump 6. The first flow resistance can be greater than the second flow resistance. This can prevent the room temperature cleaning liquid in the room temperature cleaning liquid delivery path 2 from being delivered to the first liquid pump 22 too much. That is, it can prevent the room temperature cleaning liquid from being occupied too much by the first liquid pump 22 with a large flow rate. This ensures that the second liquid pump 6 can also obtain enough room temperature cleaning liquid, and ensures that the steam delivery path can obtain enough room temperature cleaning liquid to form steam in the steam cleaning mode.

[0192] The pipeline between the first multi-port 23 and the first liquid pump 22 can have a first length, and the pipeline between the second multi-port 24 and the second liquid pump 6 can have a second length. The second length can be less than the first length, thereby increasing the first flow resistance between the first multi-port 23 and the first liquid pump 22, so that the first flow resistance is greater than the second flow resistance.

[0193] The pipeline between the first multi-port 23 and the first liquid pump 22 can have a first cross-sectional area, and the pipeline between the first multi-port 23 and the second liquid pump 6 can have a second cross-sectional area. The second cross-sectional area can be larger than the first cross-sectional area. This can also prevent the room temperature cleaning fluid from being over-occupied by the first liquid pump 22 with a larger flow rate, and ensure that the second liquid pump 6 can also obtain enough room temperature cleaning fluid.

[0194] A first number of components may be installed in the pipeline between the first multi-port 23 and the first liquid pump 22. A second number of components may be installed in the pipeline between the second multi-port 24 and the second liquid pump 6. The second number may be less than the first number, thereby allowing water to pass through more components on its path from the first multi-port 23 to the first liquid pump 22, thus increasing its first flow resistance and making the first flow resistance greater than the second flow resistance.

[0195] It should be noted that the components mentioned here can be: multi-port valves, valve bodies, liquid pumps, or other components with water flow capabilities.

[0196] The room temperature cleaning fluid delivery path 2 may further include a second multi-port 24. The second multi-port 24 may be located at a second position in the room temperature cleaning fluid delivery path 2, that is, the second multi-port 24 may be located on the pipeline between the first multi-port 23 and the first liquid pump 22. Furthermore, the second multi-port 24 may have multiple ports, and the cleaning fluid delivery path 3 can be connected to the room temperature cleaning fluid delivery path 2 through the second multi-port 24 to deliver the cleaning fluid in the cleaning delivery path to the room temperature cleaning fluid delivery path 2. Further, the input end of the first multi-port 23, the first liquid pump 22, and the output end of the third liquid pump 32 may be connected to different ports of the second multi-port 24. In this embodiment, the second multi-port 24 may be a three-way valve, that is, the second multi-port 24 may have three ports, but it is not limited to this; the second multi-port 24 may also have more than four ports.

[0197] 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.

[0198] 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 unit 11. The cleaning device 01 may have a heated cleaning mode, as shown by the solid arrow in FIG5, that is, when cleaning the surface to be cleaned, hot cleaning fluid can be delivered to the dispensing unit 11 using the hot cleaning fluid delivery path, and the hot cleaning fluid can be used in conjunction with the cleaning working part 1 for cleaning. Since the hot cleaning fluid has a higher temperature and humidity, the cleaning effect of the cleaning device 01 can be further improved compared with the normal temperature cleaning mode.

[0199] 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.

[0200] 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.

[0201] The hot cleaning fluid delivery path may include the aforementioned heater 5. That is, the hot cleaning fluid delivery path and the steam delivery path can share a single heater 5 to reduce the number of heaters 5, improve the integration of the cleaning equipment 01, and reduce the manufacturing cost of the cleaning equipment 01. The heater 5 can be turned on during the heating cleaning mode.

[0202] The ambient temperature cleaning fluid delivery path 2 may further include a first directional valve 25. The first directional valve 25 can be in a third position. Its input end can be connected to the output end of the first liquid pump 22, its first output end can be connected to the input end of the heater 5, and its second output end can be connected to the distribution unit 11. In the heating cleaning mode, the first directional valve 25 can be connected to the input end of the heater 5, allowing the ambient temperature cleaning fluid delivery path 2 to deliver ambient temperature cleaning fluid to the heater 5 through the third position. In the ambient temperature cleaning mode, the first directional valve 25 can be connected to the distribution unit 11, allowing the ambient temperature cleaning fluid delivery path 2 to directly deliver ambient temperature cleaning fluid to the distribution unit 11.

[0203] The output end of heater 5 can be connected to the room temperature cleaning liquid delivery path 2 at the fourth position. That is, the pipeline from the fourth position to the end of the room temperature cleaning liquid delivery path 2 can be reused as part of the pipeline of the hot cleaning liquid delivery path, used to deliver the hot cleaning liquid heated by heater 5 to the distribution unit 11. The fourth position can be located between the third position and the distribution unit 11, so that the water heated by heater 5 is delivered to the distribution unit 11 through the room temperature cleaning liquid delivery path 2 via the fourth position, and the hot cleaning liquid is delivered to the cleaning unit 13 or to the front of the cleaning unit 13 through the distribution unit 11.

[0204] The room temperature cleaning fluid delivery path 2 may further include a third multi-port 26. The third multi-port 26 may be located in a fourth position and may have multiple ports. The second output terminal of the first reversing valve 25, the output terminal of the heater 5, and the distributor 11 may be connected to different ports of the third multi-port 26, respectively. By setting the third multi-port 26, the room temperature cleaning fluid delivery path 2 and the hot cleaning fluid delivery path can be integrated, so that in the room temperature cleaning mode, the room temperature cleaning fluid can be directly delivered to the distributor 11 through the third multi-port 26, and in the hot cleaning mode, the room temperature cleaning fluid can be heated by the heater 5 and delivered to the distributor 11 through the third multi-port 26. In this embodiment, the third multi-port 26 may be a three-way valve, that is, the third multi-port 26 may have three ports, but it is not limited to this; the third multi-port 26 may also have multiple ports.

[0205] The hot cleaning fluid delivery path may further include a fourth multi-port 8. The fourth multi-port 8 may have multiple ports, and 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 connected to different ports of the fourth multi-port 8 respectively. By setting the fourth multi-port 8, the steam cleaning path and the hot cleaning fluid delivery path can be integrated, so that in steam cleaning mode and self-cleaning mode, room temperature cleaning fluid can enter the heater 5 through the second liquid pump 6 and the fourth multi-port 8; in heating cleaning mode, room temperature cleaning fluid can directly enter the heater 5 through the first reversing valve 25 and the fourth multi-port 8. In this embodiment, the fourth multi-port 8 can be a three-way valve, that is, the fourth multi-port 8 can have three ports, but it is not limited to this; the fourth multi-port 8 can also have multiple ports.

[0206] Furthermore, the first output terminal of the first reversing valve 25 can be connected to the first output terminal of the pressure relief valve 7, so as to deliver room temperature cleaning fluid to the pressure relief valve 7 when the pressure of the room temperature cleaning fluid delivery path 2 is too high, thereby regulating the pressure of the room temperature cleaning fluid delivery path 2. Also, with this configuration, room temperature cleaning fluid can be delivered to the heater 5 through the first pressure relief valve 7.

[0207] In some embodiments, the fourth multi-port valve 8 can be reused as a pressure relief valve 7, that is, the valve body can integrate the functions of the fourth multi-port valve 8 and the pressure relief valve 7. This configuration saves on manufacturing molds and reduces the manufacturing cost of the cleaning equipment 01. Furthermore, it reduces the number of parts in the cleaning equipment 01, saving internal space.

[0208] In some embodiments, the cleaning device 01 may further include a descaling and cleaning flow path 4. The descaling and cleaning flow path 4 may include the heater 5 described above. That is, the descaling and cleaning flow path 4 may share the heater 5 with the steam delivery flow path and / or the hot cleaning liquid delivery flow path. The descaling and cleaning flow path 4 may further include a second reversing valve 10. The input end of the second reversing valve 10 may be connected to the heater 5, the first output end of the second reversing valve 10 may be connected to the fluid output component 12, and the second output end of the second reversing valve 10 may be connected to the outside of the cleaning device 01.

[0209] The cleaning device 01 can also have a descaling cleaning mode, as shown by the solid arrows in Figures 6 and 7. In the descaling cleaning mode, the second reversing valve 10 can be connected to the outside of the cleaning device 01 to discharge scale to the outside of the cleaning device 01 via the second reversing valve 10.

[0210] In some embodiments, the heater 5 may be in a closed state during the descaling cleaning mode. Descaling agent can be added to the descaling cleaning flow path 4 to enter the heater 5 for descaling, and the descaling agent and / or scale are discharged outside the cleaning device 01 via the second reversing valve 10. Furthermore, by discharging the descaling agent and / or scale outside the cleaning device 01 via the second reversing valve 10, it is possible to prevent the descaling agent from entering the fluid output device 12 and clogging it.

[0211] The descaling and cleaning flow path 4 can be connected to the first liquid pump 22, meaning that the descaling and cleaning flow path 4 and the room temperature cleaning liquid delivery flow path 2 can share the first liquid pump 22. With this configuration, the first liquid pump 22 can be used to deliver the descaling agent, allowing for descaling maintenance of the first liquid pump 22 as well, and improving the descaling effect of the descaling agent on the first liquid pump 22 and the heater 5.

[0212] In the descaling and cleaning mode, descaling agent can be added into the descaling and cleaning flow path 4. The first liquid pump 22 can be turned on, while the second liquid pump 6 and the heater 5 are both turned off. The first reversing valve 25 can be connected to the heater 5, and the second reversing valve 10 can be connected to the outside of the cleaning equipment 01, so that the descaling agent can enter the heater 5.

[0213] In steam cleaning mode, the second directional valve 10 can connect to the fluid output component 12 to deliver steam to the fluid output component 12. In heated cleaning mode, the second directional valve 10 can connect to the distribution component 11 to deliver hot cleaning fluid to the distribution component 11.

[0214] In some embodiments, the descaling agent after descaling can be discharged to the cleaning component 13 via the second reversing valve 10. Further, the second output end of the second reversing valve 10 can be connected to the distribution component 11, allowing the descaling agent to be conveyed to the distribution component 11 via the second reversing valve 10 and then to the outside of the cleaning device 01 via the distribution component 11. For example, the descaling agent after descaling can be conveyed to the distribution component 11 via the second reversing valve 10 and then to the cleaning component 13 via the distribution component 11.

[0215] In some embodiments, the pipeline from the starting end of the ambient temperature cleaning fluid delivery path 2 to the fifth position can be reused as part of the descaling cleaning path for delivering the descaling agent to the heater 5. That is, the input end of the heater 5 can be connected to the ambient temperature cleaning fluid delivery path 2 at the fifth position. The first reversing valve 25 can be located at the fifth position, and the input end of the heater 5 can be connected to the first output end of the first reversing valve 25. The fifth position can be located between the first liquid pump 22 and the distributor 11, so that the descaling agent after descaling is delivered to the distributor 11 via the ambient temperature cleaning fluid delivery path 2 through the fifth position, and then delivered to the cleaning component 13 or to the front of the cleaning component 13 through the distributor 11, thereby discharging the descaling agent after descaling to the outside of the cleaning equipment 01.

[0216] The fifth and third positions can be the same, and the descaling and cleaning flow path 4 and the hot cleaning fluid delivery flow path can be the same. That is, the descaling and cleaning flow path 4 and the hot cleaning fluid delivery flow path can share all components. This arrangement can improve the integration and consolidation of the descaling and cleaning flow path 4 and the hot cleaning fluid delivery flow path, further improving the integration of the cleaning equipment 01 and reducing the number of redundant components.

[0217] In this embodiment, the descaling cleaning flow path 4 and the hot cleaning liquid delivery flow path can share the second reversing valve 10. The second input end of the second reversing valve 10 can be connected to the fourth multi-port 8 to deliver the hot cleaning liquid or the descaling agent after descaling to the distribution component 11 through the fourth multi-port 8.

[0218] In some embodiments, the descaling agent can be manually added to the descaling and cleaning flow path 4. Further, the descaling agent can be manually added to the supply tank 21 and then delivered to the descaling and cleaning flow path via the ambient temperature cleaning fluid delivery flow path 2.

[0219] In other embodiments, as shown in Figures 2 and 7, the descaling and cleaning flow path 4 may include: a descaling agent supply chamber 41 and a fourth liquid pump 42. The descaling agent supply chamber 41 can be used to store descaling agent, the input end of the fourth liquid pump 42 can be connected to the descaling agent supply chamber 41, and the output end of the fourth liquid pump 42 can be connected to the heater 5.

[0220] In some embodiments, the descaling agent supply chamber 41 may be located inside the liquid supply tank 21 to improve the integration of the cleaning device 01. The descaling agent inlet, the cleaning agent inlet, and the room temperature cleaning liquid inlet of the liquid supply tank 21 may be different inlets to facilitate the addition of cleaning solution and room temperature cleaning solution respectively.

[0221] In some embodiments, the heater 5 can be used to heat the cleaning fluid and deliver the hot cleaning fluid to the fluid output device 12, so that the hot cleaning fluid is delivered to the front of the cleaning device 13 through the fluid output device 12, and cleaned in conjunction with the cleaning device 13, thereby improving the cleaning effect of the cleaning device 01. The cleaning device 01 can have a powerful cleaning mode, as shown by the solid arrow in FIG7. In the powerful cleaning mode, the hot cleaning fluid can be delivered to the surface to be cleaned through the fluid output device 12 for cleaning heavy oil stains or highly stubborn dirt. In the powerful cleaning mode, the heater 5 can be turned on to heat the cleaning fluid and deliver the hot cleaning fluid to the fluid output device 12, so that the hot cleaning fluid is delivered to the front of the cleaning device 13 through the fluid output device 12.

[0222] When the surface to be cleaned is heavily soiled with oil or has stubborn dirt, the powerful cleaning mode can be switched to, allowing the cleaning device 01 to achieve better cleaning results with higher energy consumption. Furthermore, switching to the powerful cleaning mode only when the dirt is heavily soiled with oil or has stubborn dirt reduces the time the cleaning device 01 operates in a high-energy-consumption state, thus achieving energy savings.

[0223] In some embodiments, the cleaning device 01 may include a powerful cleaning flow path. The powerful cleaning flow path may include a third heat exchange valve and a heater 5. The heater 5 may be the heater 5 described above, that is, the powerful cleaning flow path may share the heater 5 with the steam cleaning flow path, the heated cleaning flow path and the descaling cleaning flow path 4, thereby further improving the integration of the cleaning device 01.

[0224] The input end of the third heat exchange valve can be connected to the output end of the heater 5, the first output end of the third directional valve 14 can be connected to the fluid output component 12, and the second output end of the third directional valve 14 can be connected to the distribution component 11. In the powerful cleaning mode, the heater 5 can be in the open state, and the third directional valve 14 can be connected to the fluid output component 12 to deliver hot cleaning fluid to the fluid output component 12. In the heated cleaning mode, the third directional valve 14 can be connected to the distribution component 11 to deliver hot cleaning fluid to the distribution component 11.

[0225] The powerful cleaning flow path can be connected to a first liquid pump 22, which can be used to deliver room temperature cleaning liquid to the heater 5, thereby increasing the amount of room temperature cleaning liquid entering the powerful cleaning flow path and further improving the cleaning effect of the powerful cleaning flow path.

[0226] 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.

[0227] 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.

[0228] 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 shown by the solid arrow in FIG8, the second liquid pump 6 and the heater 5 are in the on state to heat the cleaning liquid to generate steam, and 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 device 01 and reducing the number of redundant components.

[0229] 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.

[0230] In some embodiments, the fourth reversing valve 15 and the second reversing valve 10 can be the same reversing valve. This configuration can further improve the integration of the cleaning device 01 and reduce the number of unnecessary components. Furthermore, the self-cleaning flow path and part of the steam delivery flow path can be the same, that is, 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 reversing valve 10.

[0231] In some embodiments, the third, fifth, and sixth positions may all be the same, and the second directional valve 10, the third directional valve 14, and the fourth directional valve 15 may all be the same, but are not limited thereto.

[0232] In some embodiments, as shown in Figures 1 to 9, the room temperature cleaning fluid delivery path 2 may further include a flow detector 27. The flow detector 27 may be a flow sensor or the like. The flow detector 27 may be located between the supply tank 21 and the first position to detect the amount of water entering the room temperature cleaning fluid delivery path 2 from the supply tank 21. Furthermore, by detecting whether there is water in the room temperature cleaning fluid delivery path 2, it can be determined whether to turn on the heater 5, to prevent the heater 5 from running dry and reducing the probability of damage to the heater 5.

[0233] In some embodiments, a preset time can be set so that the heater 5 can only be turned on when the flow detector 27 detects water in the room temperature cleaning fluid delivery path 2 for the entire preset time. The preset time can be 3 seconds, but is not limited to this.

[0234] In some embodiments, a control method for a cleaning device 01 is provided. As shown in Figures 1 to 15, the control method for the cleaning device 01 can be used to control the cleaning device 01 described above.

[0235] 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. Therefore, in this embodiment, the specific structure and beneficial effects of the cleaning device 01 will not be described again. Please refer to the specific description in the previous embodiment. All of these are within the protection scope of this disclosure.

This allows the cleaning liquid and a portion of the room temperature cleaning liquid to be directly delivered to the distributor 11 through the room temperature cleaning liquid delivery path 2, while another portion of the room temperature cleaning liquid enters the steam delivery path via the first multi-port 23. The cleaning liquid can be heated by the heater 5 to form steam, and the steam can be delivered to the fluid output device 12 through the steam delivery path.

[0245] In some embodiments, the cleaning mode command may further include a heating cleaning command. The control method for the cleaning device 01 may further include:

The first liquid pump 22 can be turned on, the second liquid pump 6 can be turned off, and the first reversing valve 25 can be connected to the input of the heater 5. This opens the cleaning liquid delivery path 3, allowing room temperature cleaning liquid and cleaning liquid to enter the heater 5.
