Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The cleaning device described in the embodiments of the cleaning device may be a device having at least one of dust collection, sweeping, mopping, and washing. In some examples, the cleaning device may also be referred to as a cleaner, sweeper, mopping machine, or scrubber. With the continued iteration of cleaning devices, more and more cleaning devices have increased steam functionality to achieve better cleaning.
The inventor of the application has long studied and found that when the steam generating component in the cleaning device is subjected to scale removal, citric acid can be manually added into the cleaning device when the cleaning device is in an operating state. The citric acid can react with the scale in the steam generating assembly to achieve the effect of cleaning the scale. However, during the reaction, part of the citric acid easily overflows or flows out with the steam. This can result in the flow of vapors or liquids containing citric acid to the surface, causing contamination. In addition, the efficiency of removing scale from citric acid is also not ideal due to the high reaction temperature. In order to solve the above technical problems, the present application proposes the following embodiments.
In the cleaning apparatus embodiment of the present application, as shown in fig. 1 and 2, the cleaning apparatus 10 may include a housing 100, a steam generating assembly 200, and a controller 300. Wherein the steam generation assembly 200 and the controller 300 may be provided to the case 100. The housing 100 may refer to the outer shell of the overall cleaning device 10.
In some examples, the housing 100 may be provided with a cleaning liquid receiving chamber 110. Wherein the cleaning solution receiving chamber 110 may be used to receive and store fresh water or mixed cleaning solution. For example, the cleaning liquid receiving chamber 110 may be used to receive fresh water for storage during operation with the cleaning apparatus 10. The cleaning solution receiving chamber 110 may be used to receive a mixed cleaning solution when a descaling operation is required. The cleaning solution receiving chamber 110 may also be used to receive fresh water when it is desired to remove residual mixed cleaning solution. In some examples, the cleaning liquid containing chamber 110 may be open to the clean water tank. Wherein the clean water tank may be detachably provided to the housing 100.
In some examples, the mixed cleaning solution may be prepared based on an acidic cleaner. In other words, a mixed cleaning solution can be formed based on the acidic cleaning agent. Wherein the acidic cleaning agent may comprise citric acid. That is, the mixed cleaning solution may include citric acid. In some examples, the ratio of the mass ratio or molar amount of citric acid to clear water in the mixed rinse is 1:1 to 1:5, 1:5.1 to 1:10, 1:10.1 to 1:15, 1:15.1 to 1:20, or 1:20.1 to 1:30.
In some examples, the steam generation assembly 200 may include a steam pump 210, a steam boiler 220, and a conduit 230. Wherein the steam boiler 220 may communicate with the cleaning liquid containing chamber 110 through the steam pump 210. The steam pump 210 is used to pump the liquid in the cleaning liquid receiving chamber 110 into the steam boiler 220. The pipe 230 is used to communicate the steam boiler 220 with the outside. In some examples, the conduit 230 may be used to output steam to the area 2 to be cleaned. In particular, steam generated inside the steam boiler 220 may be output toward the region 2 to be cleaned through the pipe 230. In this case, some stains or trash which are difficult to treat in the area to be cleaned 2 can be softened, thereby improving the cleaning effect.
In some examples, the controller 300 may electrically connect the steam pump 210 and the steam boiler 220. Wherein the controller 300 can control the steam pump 210 to drive the liquid (clean water or mixed cleaning liquid) in the cleaning liquid containing chamber 110 to be pumped to the steam boiler 220. In addition, the controller 300 may control the temperature of the steam boiler 220. For example, when cleaning using the cleaning apparatus 10 is desired, the controller 300 may control the steam boiler 220 to heat the fresh water therein to a steam generating temperature. When it is desired to scale the cleaning apparatus 10, the steam boiler 220 may be controlled to heat the mixed cleaning solution therein to a first preset temperature below the steam generating temperature. When the cleaning of the mixed cleaning liquid remaining inside the steam generating assembly 200 is required, the steam boiler 220 may not be heated.
In some examples, the first preset temperature may have a value ranging from 30 ℃ to 35 ℃, 35.1 ℃ to 40 ℃, 40.1 ℃ to 45 ℃, 45.1 ℃ to 50 ℃, 50.1 ℃ to 55 ℃, or 55.1 ℃ to 60 ℃.
The controller 300 may be used to control the steam pump 210 to inject the mixed cleaning solution into the steam boiler 220 while the steam boiler 220 performs the descaling operation. In addition, the controller 300 may control the steam boiler 220 to heat the mixed cleaning solution therein to a first preset temperature for the mixed cleaning solution to react with the dirt in the steam boiler 220 at the first preset temperature. The mixed liquor after the mixed liquor reacts with the dirt in the steam boiler 220 can flow out through the pipe 230 so as to react with the dirt in the pipe 230.
The mixed cleaning solution is added in the steam boiler 220, and the mixed cleaning solution is heated to a first preset temperature lower than the steam generation temperature by the steam boiler 220 to provide an environment suitable for the reaction of the mixed cleaning solution and the scale. On one hand, the descaling efficiency and effect can be improved; on the other hand, the risk of pollution or injury to users caused by overflow of mixed cleaning liquid along with steam in the descaling process can be avoided.
It is considered that the user does not necessarily have to be aware of whether the cleaning apparatus 1 needs to perform the descaling operation. Thus, in some examples, the controller 300 may automatically determine whether the cleaning apparatus 1 requires descaling. Specifically, the controller 300 is used to determine whether the steam boiler 220 needs to perform a descaling operation based on the operation data of the steam boiler 220. If it is determined that the steam boiler 220 needs to perform the descaling operation, the steam boiler 220 is subjected to the descaling operation. If it is determined that the descaling operation of the steam boiler 220 is not required, the descaling operation of the steam boiler 220 is not performed.
In some examples, the operational data may include an operating duration of the steam boiler 220. The controller 300 may be used to record the operating time period of the steam boiler 220 and determine whether the operating time period is less than a preset time period. If the working time period is not less than the preset time period, it is determined that the steam boiler 220 needs to perform the descaling operation, and if the working time period is less than the preset time period, it is determined that the steam boiler 220 does not need to perform the descaling operation. In this case, the scale in the steam generating assembly 200 can be cleaned in time. In the use scene of harder water quality, the preset duration can be configured to be shorter. In the use scene with softer water quality, the preset time period can be configured to be longer.
In some examples, the operational data may include an actual operating temperature of the steam boiler 220. In some examples, the controller 300 may also obtain a theoretical temperature of the steam boiler 220. Specifically, the controller 300 may be used to obtain the water intake and corresponding heating power of the steam boiler 220. Generally, when the heating power is the same, the larger the water inflow amount is, the smaller the temperature increase rate or the lower the temperature of the steam boiler 220 is. Accordingly, the theoretical temperature of the steam boiler 220 may be calculated based on the inflow amount of the steam boiler 220 and the corresponding heating power.
In some examples, the controller 300 is configured to obtain an actual temperature of the steam boiler and determine whether the actual temperature is greater than a theoretical temperature. If the actual temperature is greater than the theoretical temperature, it means that the amount of water entering the steam boiler 220 is not as great as expected without changing the heating power, which may mean that too much water scale in the steam generating assembly 200 causes clogging, or that too much water scale in the steam boiler 220 causes a decrease in the volume inside the steam boiler 220. If the actual temperature is greater than the theoretical temperature, it is determined that the steam boiler 220 needs to perform the descaling operation, and if the actual temperature is not greater than the theoretical temperature, it is determined that the steam boiler 220 does not need to perform the descaling operation. In this case, the controller 300 can accurately determine whether or not the cleaning apparatus 10 needs to be descaled.
Specifically, the steam generating assembly 200 may further include a temperature sensor 240 provided to the steam boiler 220. The temperature sensor 240 is used to measure the actual temperature of the steam boiler 220. The temperature sensor 240 may be electrically connected to the controller 300. In this case, the controller 300 may acquire the actual temperature of the steam boiler 220 through a temperature sensor.
Based on the same principle, the controller 300 may be configured to acquire an actual temperature of the steam boiler 220 when the descaling operation of the steam boiler 220 is performed, and determine whether a difference between the actual temperature and a first preset temperature is greater than a preset threshold. If so, the heating power of the steam boiler 220 is adjusted so that the difference is smaller than a preset threshold. In this case, the temperature of the steam boiler 220 and the water inside the steam boiler 220 can be maintained, and the mixed cleaning solution can be reacted with the scale at an appropriate temperature, thereby improving the reaction efficiency.
In some examples, the cleaning device 10 includes a power source electrically connected to the controller 300. The power supply is used to supply power to the steam boiler 220, the controller 300, etc. with the power components. The steam generating assembly 200 includes a temperature control switch. The temperature control switch is electrically connected between the steam boiler 220 and the power supply. The temperature control switch is used for switching off when the actual temperature is greater than or equal to a second preset temperature. In this case, further heating of the steam boiler 220 can be stopped.
In some examples, the cleaning apparatus 10 may require that a mixed cleaning solution or clear water be injected into the cleaning solution receiving chamber 110. Thus, the cleaning apparatus 10 can communicate with the outside. For example, the cleaning device 10 may communicate to an external robotic arm or robot such that the robotic arm or robot receives instructions to add mixed cleaning solution or fresh water to the cleaning device 10.
In some examples, the cleaning device 10 may include a human-machine interaction component 400 electrically connected to the controller 300. The controller 300 may be used to issue different prompts to the customer at different stages. The user may also issue instructions to the controller 300 through the human-machine interaction component 400. For example, when the controller 300 determines that the steam boiler 220 needs to perform the descaling operation based on the operation data, the user may be timely reminded of descaling the cleaning apparatus 10.
Specifically, when it is determined that the steam boiler 220 needs to perform the descaling operation, the human-computer interaction assembly 400 may prompt the user to add the mixed cleaning solution into the cleaning solution accommodating cavity 110, or add the acidic cleaning agent into the clean water in the cleaning solution accommodating cavity 110 to form the mixed cleaning solution. In other examples, the human-machine interaction assembly 400 may prompt the user to remove the clear water tank and add the mixed cleaning solution to the clear water tank. When the controller 300 recognizes that the fresh water tank is mounted to the housing 100, it may control to perform the descaling operation. That is, in some examples, the descaling operation may include alerting the user to add the mixed cleaning solution. In other examples, if the cleaning apparatus 10 has a preset mixed cleaning solution and uses the mixed cleaning solution for descaling, the descaling operation may not include prompting the user to add the mixed cleaning solution.
When the cleaning solution accommodating chamber 110 is used for accommodating clean water after the steam boiler 220 is subjected to the descaling operation, the controller 300 may be used for reminding a user to add clean water into the cleaning solution accommodating chamber 110 through the man-machine interaction assembly 400 after the steam boiler 220 is subjected to the descaling operation, and controlling the steam pump 210 to pump the clean water in the cleaning solution accommodating chamber 110 into the steam boiler 220. In other examples, the human-machine interaction assembly 400 may prompt the user to remove the clean water tank and add clean water to the cleaning solution receiving chamber 110 after the descaling operation of the steam boiler 220 is completed.
In some examples, the controller 300 may acquire the liquid volume in the cleaning liquid containing chamber 110. Specifically, when the volume of the mixed washing liquid in the washing liquid containing chamber 110 is sufficient, the controller 300 may send corresponding information to the user through the man-machine interaction assembly 400. For example ready to be descaled or to start descaling. When the mixed cleaning solution in the cleaning solution accommodating chamber 110 is used, it is judged that the descaling operation of the steam boiler 220 is completed.
Referring to fig. 3 and 4, in some examples, the cleaning apparatus 10 may include a roller brush assembly 500 and a suction assembly 600 electrically connected to the controller 300. Wherein the roller brush assembly 500 and the suction assembly 600 may be provided to the housing 100.
In some examples, the roller brush assembly 500 is used to clean the area 2 to be cleaned. Specifically, the roller brush assembly 500 may contact the region 2 to be cleaned and output a rolling motion to clean the region 2 to be cleaned.
In some examples, the housing 100 is further provided with a suction port and a stain receiving chamber in communication with the suction port. The suction assembly 600 is used to suck the stain into the stain receiving cavity through the suction port. In this case, the cleaned dirt can be transferred in time, and the cleaning effect can be improved. In particular, the suction assembly 600 may include a blower. The fan can provide power for the transfer of the mixed liquor.
In some examples, the controller 300 is configured to control the operation of the roller brush assembly 500 while the steam boiler 220 is performing the descaling operation and simultaneously control the suction assembly 600 to suck the mixed liquor flowing out through the duct 230 into the stain receiving chamber. In some examples, the transfer of the mixed liquor to the stain receiving chamber may be accomplished on the charging dock 20.
In some examples, the charging dock 20 is a device that is used with the cleaning device 10 to charge the cleaning device 10. The principle and method of charging the battery of the cleaning device 10 by the charging stand 20 are not limited herein.
In some examples, the controller 300 is used to detect whether the cleaning apparatus 10 is placed at a preset position of the charging stand 20 before the descaling operation of the steam boiler 220. If yes, performing descaling operation on the steam boiler 220; if not, the descaling operation is not performed on the steam boiler 220. If it is detected that the cleaning device 10 is not placed at the preset position of the charging stand 20, the user may be timely reminded to put the cleaning device 10 back to the charging stand 20 through the human-computer interaction assembly 400.
Referring to fig. 5, when the steam boiler 220 is placed at a preset position of the charging stand 20, the reacted mixed liquid flowing out of the pipe 230 when the steam boiler 220 performs the descaling operation is introduced into the water storage tank 21 of the charging stand. The roller brush assembly 500 is configured to be operable to spin the liquid in the reservoir 21 to the suction port by rotation. The suction assembly 600 is used to suck the liquid in the reservoir 21 into the stain receiving chamber through the suction port. In some examples, the roller brush assembly 500 may be disposed opposite the reservoir 21 and at least partially within the reservoir 21. In this case, the mixed solution can be temporarily stored in the water storage tank 21 and transferred to the stain receiving chamber in time, so that the possibility of environmental pollution can be reduced.
Considering that the water storage tank 21 generally has a predetermined volume, it is difficult for the roller brush assembly 500 to transfer the mixed liquid to the suction port when the mixed liquid stored in the water storage tank 21 is small. In some examples, the controller 300 is configured to control the roller brush assembly 500 and the suction assembly 600 to intermittently operate to suck the mixed liquor flowing out through the duct 230 into the stain receiving chamber while the steam boiler 220 performs the descaling operation. In this case, the power consumption of the roller brush assembly 500 and the suction assembly 600 can be reduced, and the mixed liquid can be timely sucked into the soil accommodating chamber.
Specifically, the roller brush assembly 500 and the suction assembly 600 may be operated once every 1-2 minutes, 2-3 minutes, 3-4 minutes, 4-5 minutes, 5-6 minutes, or 6-15 minutes. Wherein the run time may last 1-2 seconds, 2-3 seconds, 3-4 seconds, 4-5 seconds, 5-7 seconds, 7-10 seconds, 10-15 seconds, 15-30 seconds, 30-60 seconds, 1-5 minutes, or 5-10 minutes.
It is contemplated that the stain receiving chamber will generally have a predetermined volume. In some examples, the controller 300 can also be used to monitor the volume of liquid in the stain receiving chamber. When the ratio of the volume of liquid in the soil containing chamber to the volume of the soil containing chamber reaches a preset value (e.g., 80%, 85%, 90%, 92% or 96%), the descaling operation may be discontinued and the user may be alerted to clean the soil containing chamber. When the controller 300 detects that the soil containing chamber is reset and the ratio of the volume of the liquid in the soil containing chamber to the volume of the soil containing chamber is below a preset value, the descaling operation may be continued.
Based on the above description of the embodiments of the cleaning apparatus of the present application, the following embodiments of the descaling method of the cleaning apparatus of the present application exemplarily describe the descaling method of the cleaning apparatus 10.
Referring to fig. 6 and 7, in some examples, the descaling method may include:
step S1100: when the steam boiler 220 performs the descaling operation, the steam pump 210 is controlled to inject the mixed cleaning liquid into the steam boiler 220; step S1200: controlling the steam boiler 220 to heat the mixed cleaning solution therein to a first preset temperature lower than the steam generation temperature so that the mixed cleaning solution reacts with dirt in the steam boiler 220 at the first preset temperature; step S1300: the mixed liquor after the reaction of the mixed cleaning solution and the dirt in the steam boiler 220 is discharged through the pipe 230, so that the reacted mixed liquor can react with the dirt in the pipe in the discharging process.
This embodiment is described in further detail below.
In some examples, before step S1100, step S1000 may be further included: it is determined whether the steam boiler 220 needs to perform a descaling operation.
In step S1000, it may be determined whether the steam boiler 220 needs to perform a descaling operation based on the operation data of the steam boiler 220. If the determination result is yes, step S1020 may be executed: the control man-machine interaction assembly 400 prompts the user to place the cleaning device 10 on the charging stand 20 or to perform step S1100. That is, the descaling operation may include controlling the human-computer interaction assembly 400 to remind the user to place the cleaning device 10 on the charging stand 20. If the judgment result is negative, the descaling operation is not executed. The description of the operation data may be described with reference to the embodiments of the cleaning apparatus 10 described above, and will not be repeated herein.
In some examples, the descaling method may further include step S1025: it is determined whether the cleaning device 10 is placed at a preset position of the charging stand 20. If the determination result is yes, step S1040 may be performed: the control man-machine interaction assembly 400 prompts the user to add the mixed cleaning solution into the cleaning solution receiving chamber 110. If the determination result is no, step S1020 is performed.
In some examples, step S1040 may include: the man-machine interaction component 400 is controlled to prompt a user to take out the clear water tank; after the clean water tank is taken out, reminding a user to add the mixed cleaning solution into the cleaning solution accommodating cavity 110; the control man-machine interaction assembly 400 alerts the user to put the fresh water tank back.
In some examples, step S1040 may include: it is judged whether or not citric acid is present in the cleaning liquid containing chamber 110. If the determination is yes, a determination may be performed as to whether the amount of water in the cleaning liquid accommodating chamber 110 reaches a preset volume, or step S1100 may be performed. If the determination result is no, step S1040 may be performed: the control man-machine interaction assembly 400 prompts the user to add the mixed cleaning solution into the cleaning solution receiving chamber 110. Regarding the step of determining whether the amount of water in the cleaning liquid accommodating chamber 110 reaches the preset volume, if so, step S1100 may be performed. If the determination result is no, step S1040 may be performed.
In other examples, the mixed cleaning solution may be added to the cleaning solution containing chamber 110 without removing the cleaning solution tank. In this case, the descaling operation may include directly performing step S1040.
In other examples, step 1040 may also not include determining whether citric acid is present in the cleaning solution receiving chamber 110 and/or determining whether the amount of water in the cleaning solution receiving chamber 110 reaches a predetermined volume.
In step S1100, in some examples, the steam pump 210 may be controlled to pump the mixed cleaning liquid in the cleaning liquid containing cavity 110 into the steam boiler 220.
In step S1200: the steam boiler 220 is controlled to heat the mixed cleaning solution therein to a first preset temperature lower than the steam generation temperature for the mixed cleaning solution to react with the dirt in the steam boiler 220 at the first preset temperature. The first preset temperature and the temperature control method of the steam boiler may be described with reference to the above embodiments of the cleaning apparatus 10 of the present application, which are not described herein.
In step S1300: the mixed liquor after the reaction of the mixed cleaning solution and the dirt in the steam boiler 220 is discharged through the pipe 230, so that the reacted mixed liquor can react with the dirt in the pipe in the discharging process. The mixed liquor may flow to the reservoir via line 230.
In some examples, the descaling method may further include controlling the operation of the roller brush assembly 500 to spin the liquid in the water storage tank 21 to the suction port by rotation, and controlling the suction assembly 600 to suck the liquid in the water storage tank 21 into the stain receiving chamber through the suction port. The working principles of the rolling brush assembly 500 and the suction assembly 600 may be described with reference to the embodiments of the cleaning apparatus 10 described above, and are not described herein.
In some examples, the method of descaling may further include determining whether a ratio of a volume of the liquid in the stain receiving chamber to a volume of the stain receiving chamber reaches a preset value. If the result is yes, the descaling operation is stopped, and the user is prompted to clean the dirt accommodating cavity. If the determination result is no, the step S1300 is continuously executed: the mixed liquor after the reaction of the mixed cleaning solution and the dirt in the steam boiler 220 is discharged through the pipe 230, so that the reacted mixed liquor can react with the dirt in the pipe in the discharging process.
In some examples, the user may remove the stain containment chamber to clean the mixed liquor therein. In this case, the controller may also alert the user to reset the stain receiving chamber through the human-machine interaction assembly 400. When the controller 300 detects that the stain receiving chamber is reset, a determination may be performed as to whether the ratio of the volume of the liquid in the stain receiving chamber to the volume of the stain receiving chamber reaches a preset value.
In some examples, the descaling method may further include step S1350: it is determined whether the mixed cleaning liquid in the cleaning liquid accommodating chamber 110 is used. If the determination result is yes, the descaling process may be ended, or step S1400 may be performed: the steam pump 210 is controlled to inject clear water into the steam generating assembly 200 or to perform step S1420 (described later) to wash the mixed cleaning solution remaining inside the steam generating assembly 200. If not, the process continues to step S1300.
In step S1400: the steam pump 210 is controlled to inject the clean water into the steam generating assembly 200 to wash the mixed cleaning solution remaining inside the steam generating assembly 200.
In some examples, the descaling method may include step S1420: the man-machine interaction assembly 400 is controlled to remind the user to add clear water into the cleaning solution containing chamber 110. Specifically, the human-computer interaction component 400 is controlled to prompt the user to take out the clear water tank; after the clean water tank is taken out, reminding a user to add clean water into the clean water accommodating cavity 110; the control man-machine interaction assembly 400 alerts the user to put the fresh water tank back. In other examples, the fresh water may be added to the cleaning solution receiving chamber 110 without removing the fresh water tank.
In some examples, the descaling method may further include step S1440: it is determined whether the amount of water in the cleaning liquid accommodating chamber 110 reaches a preset volume. If the determination is yes, step S1400 may be performed. If the determination result is negative, step S1420 may be performed.
In some examples, determining whether the ratio of the volume of the liquid in the stain-containing chamber to the volume of the stain-containing chamber reaches the preset value may also be used in step S1400, and will not be described herein.
