Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to a washing device and a cleaning method for an inner drum tripod. Background Art

[0002] A washing machine is a special cleaning device used to wash clothes and textiles such as cotton, linen, and chemical fibers. Current washing machines, whether fully automatic or semi-automatic, basically have the three basic functions of washing, rinsing, and dehydrating, which to a certain extent reduce people's labor intensity and make people's lives more comfortable.

[0003] Existing washing machines are roughly divided into two types: pulsator washing machines and drum washing machines, and their structural design generally includes an inner drum and an outer drum. After long-term use, the dirt washed out is likely to remain on the wall of the inner drum, especially the tripod part of the inner drum. If it is not cleaned for a long time, it is easy to accumulate dirt and even breed bacteria, causing secondary pollution of the washing machine, affecting the washing effect and user experience, and in severe cases endangering the health of the user.

[0004] There are many sterilization methods used in washing machines on the market, such as high-temperature water washing combined with disinfectant, ultraviolet sterilization, ozone sterilization, and silver ion sterilization. Although these sterilization methods can kill the bacteria attached to the inner drum of the washing machine or inactivate the bacteria to a certain extent, they cannot directly remove the dirt on the inner drum wall. It won’t take long for bacteria to breed in the dirt again. Therefore, they cannot fundamentally solve the secondary pollution problem faced by washing machines.

[0005] The Chinese patent application number 201620488652.9 discloses a drum washing machine inner barrel rear wall. The patent divides the integrally stamped inner barrel rear wall into two parts, and the middle structure is designed as a transparent plastic part. Through the transparent plastic part, the inner and outer barrels, such as the tripod and the outer barrel wall, can be observed to determine whether they need to be cleaned. If they need to be cleaned, the middle part can be simply disassembled. After disassembly, the area between the inner barrels is exposed, and the tripod, the inner wall of the outer barrel, and the outer wall of the inner barrel can be manually cleaned. This patent requires manual cleaning of the tripod, etc. only after disassembly, which is time-consuming and labor-intensive, and cannot realize automatic detection and judgment of dirtiness, resulting in a poor user experience.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing device. The dirtiness of the surface of a tripod is detected by a dirtiness detection device. When the dirtiness of the surface of the tripod reaches a preset dirtiness, the spray cleaning module and the ultrasonic cleaning module are turned on. The surface of the tripod is spray cleaned by the rotatable spray cleaning module, and then the tripod is ultrasonically cleaned by the ultrasonic cleaning module. Through the cooperation of the two, the dead corners of the tripod are well cleaned, and secondary pollution can be effectively prevented. Compared with traditional manual cleaning, disassembly is avoided, time and labor are saved, and the cleaning effect is better.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: to provide a washing device, comprising:

[0009] The inner drum is rotatable and used for washing clothes;

[0010] A tripod, arranged at the bottom of the inner drum, for rubbing clothes;

[0011] A dirtiness detection device, used to detect the dirtiness of the tripod surface;

[0012] A spray cleaning module is rotatably disposed at the bottom of the inner cylinder and is used for spray cleaning the surface of the tripod;

[0013] An ultrasonic cleaning module, disposed on the tripod, for ultrasonically cleaning the tripod;

[0014] When the dirtiness detection device detects that the dirtiness of the tripod surface reaches a preset dirtiness, the spray cleaning module and the ultrasonic cleaning module start to work.

[0015] Furthermore, the tripod comprises a plurality of arms, one end of each arm is fixedly connected, and the other end is spaced apart along the circumference of the inner tube;

[0016] The spray cleaning module is rotatably mounted on the bottom wall of the inner cylinder and is located at the interval of the support arms. The spray cleaning module can be rotated 360 degrees.

[0017] In the above scheme, by setting the spray cleaning module at the interval of the support arm, the spray cleaning module is located on the side of the tripod, so that the outer surface of the tripod can be cleaned; and the spray cleaning module is set to be rotatable 360°, so that the spray cleaning module can perform all-round spray cleaning on the outer surface of the tripod, thereby achieving cleaning of the tripod without dead ends.

[0018] Furthermore, a portion of the bottom wall of the inner cylinder corresponding to the position of the spray cleaning module is recessed toward the bottom of the inner cylinder, so that the height of the spray cleaning module protruding from the bottom wall of the inner cylinder is less than the height of the tripod.

[0019] In the above scheme, the spray cleaning module is recessed on the bottom wall of the inner drum to ensure that the spray cleaning module can spray to the junction of the tripod and the bottom wall of the inner drum. Because this is a dead corner, it is easy to hide dirt and grime, and avoid the dirt in the dead corner being not cleaned thoroughly, resulting in secondary pollution; at the same time, it is also to prevent the spray cleaning module from occupying the washing space in the inner drum to ensure the smooth execution of the washing process.

[0020] Furthermore, it also includes a liquid inlet module connected to the spray cleaning module and used to provide cleaning liquid to the spray cleaning module;

[0021] The spray cleaning module is provided with a spray hole, and the spray hole is used to spray cleaning liquid onto the surface of the tripod.

[0022] Furthermore, the surface of the spray cleaning module is arranged with a smooth transition.

[0023] In the above scheme, the surface of the spray cleaning module is set with a smooth transition, which can not only prevent the spray cleaning module from scratching clothes, but also the smooth transition surface is equivalent to a stirring rib, which can contact and collide with clothes to assist in washing clothes.

[0024] Furthermore, the ultrasonic cleaning module is arranged at the fixed connection of the support arm, and includes:

[0025] An ultrasonic generator for emitting high-frequency vibration signals;

[0026] The transducer is used to convert the high-frequency vibration signal into the mechanical vibration of the tripod and the inner cylinder.

[0027] In the above scheme, by arranging the ultrasonic cleaning module at the fixed connection of the support arm, it is convenient to convert the high-frequency vibration signal emitted by the ultrasonic generator into the mechanical vibration of the entire tripod and the inner cylinder, and vibrate the dirt on the tripod and the inner cylinder, especially the dirt in the dead corners, to achieve cleaning without dead corners.

[0028] Furthermore, the turbidity detection device includes a light transmittance sensor, which is arranged on the surface of the tripod and is used to detect the transmittance of the tripod surface. When the transmittance is less than a preset transmittance, the spray cleaning module and the ultrasonic cleaning module start working in sequence.

[0029] In the above scheme, during the operation of the spray cleaning module and the ultrasonic cleaning module, the light transmittance sensor is also in operation to detect the light transmittance of the tripod surface in real time.

[0030] A method for cleaning an inner drum tripod is applied to a washing device as described above, the method comprising:

[0031] Detect the light transmittance of the tripod surface;

[0032] Determining that the light transmittance is less than a preset light transmittance;

[0033] Perform the tripod cleaning procedure;

[0034] Turn on the spray cleaning module and rotate it while spraying the cleaning liquid;

[0035] Turn on the ultrasonic cleaning module to perform ultrasonic cleaning;

[0036] Check that the cleaning of the tripod meets the preset requirements;

[0037] End the cleaning process.

[0038] In the above scheme, when the transmittance is less than the preset transmittance, it indicates that the surface of the tripod is highly dirty, that is, it is judged that the inner tube of the tripod needs to be cleaned; first, the cleaning module is rotated and sprayed with cleaning liquid, the cleaning liquid contains a cleaning agent, which has the effects of softening and decomposing the dirt. The dirt is first soaked with the cleaning liquid, and then the ultrasonic cleaning module is turned on. The stubborn dirt can be ultrasonically shaken off very quickly, which can effectively save cleaning time and improve the cleaning effect.

[0039] Further, starting the ultrasonic cleaning module to perform ultrasonic cleaning includes:

[0040] Control to turn on the ultrasonic generator to emit a high-frequency vibration signal;

[0041] The control turns on the transducer to convert the high-frequency vibration signal into mechanical vibration of the tripod and the inner cylinder.

[0042] Furthermore, the cleaning of the testing tripod meets the preset requirements including:

[0043] Detect the real-time light transmittance of the tripod surface during cleaning;

[0044] Obtaining the rate of change of light transmittance;

[0045] It is determined that the change rate is less than a preset change rate;

[0046] Wherein, the change rate = (real-time transmittance - transmittance) / 100%.

[0047] In the above scheme, during the cleaning process, as the cleaning time increases, the dirt on the surface of the tripod is gradually cleaned off, the degree of dirt gradually decreases, and the transmittance gradually increases, so the real-time transmittance is greater than or equal to the transmittance of the initial detection; when the change rate of the transmittance is less than the preset change rate, it indicates that the transmittance tends to be stable and the change is small, further indicating that the dirt on the tripod has been basically cleaned completely and the preset cleaning requirements have been met.

[0048] Furthermore, the cleaning of the testing tripod meets the preset requirements including:

[0049] Detect the real-time light transmittance of the tripod surface during cleaning;

[0050] Determine whether the real-time light transmittance is greater than or equal to the preset light transmittance.

[0051] In the above scheme, when the real-time light transmittance is greater than or equal to the preset light transmittance, it indicates that the dirt on the tripod has been basically cleaned completely and the preset cleaning requirements have been met.

[0052] Further, detecting whether the cleaning of the tripod has reached a preset requirement includes: detecting whether the ultrasonic time has reached a preset ultrasonic time.

[0053] In the above scheme, when the ultrasonic time reaches the preset ultrasonic time, it indicates that the dirt on the tripod has been basically cleaned completely and the preset cleaning requirements have been met.

[0054] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0055] 1. The present invention provides a cleaning method for an inner cylinder tripod, which determines the degree of dirtiness of the tripod by detecting the light transmittance of the tripod surface, and cleans the tripod and the inner cylinder by a combination of spray cleaning and ultrasonic cleaning. The method can not only clean the dirt on the tripod and the inner cylinder, but also has a good cleaning effect on the dead corners of the tripod, and can effectively prevent secondary pollution. Compared with traditional manual cleaning, the method avoids disassembly, saves time and effort, and has a better cleaning effect.

[0056] 2. The present invention uses the change rate of transmittance less than the preset change rate, the real-time transmittance greater than or equal to the preset transmittance, and the ultrasonic time reaching the preset ultrasonic time as the standard for judging that the dirt on the tripod has been basically cleaned and has met the preset cleaning requirements. The above judgment conditions can be used as a single judgment standard, or the above judgment conditions can be combined as a comprehensive judgment standard. It can be set as needed to improve the accuracy of the judgment.

[0057] 3. The present invention automatically detects the degree of dirtiness of the tripod before or after washing clothes, and automatically executes and ends the ultrasonic cleaning program according to the judgment result. The whole process is fully automated, replacing manual cleaning, and improving the user experience while ensuring the cleaning effect.

[0058] 4. The present invention also provides a washing device that adopts the cleaning method of the inner cylinder tripod as described above. The washing device uses a rotatable spray cleaning module and an ultrasonic cleaning module to clean the tripod and the inner cylinder. On the basis of ensuring a cleaning effect without dead angles, it has the characteristics of simple structure, easy use and low cost.

[0069] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected", "abutted" and the like should be understood in a broad sense, for example, it can be a detachable connection, a mechanical connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0070] After long-term use of the washing machine, the dirt washed out is easy to remain on the wall of the inner drum, especially the tripod part of the inner drum. If it is not cleaned for a long time, it is easy to accumulate dirt and even breed bacteria, causing secondary pollution of the washing machine, affecting the washing effect and user experience. The existing cleaning of the inner drum tripod is mostly manual, and the washing machine needs to be disassembled, which is time-consuming and labor-intensive. Not only is the cleaning effect poor, but also automatic cleaning cannot be achieved. In order to solve this problem, the present invention provides a washing device and a cleaning method for the inner drum tripod, which uses a combination of spray cleaning and ultrasonic cleaning to clean the tripod and the inner drum, which can not only clean the dirt on the tripod and the inner drum, but also has a good cleaning effect on the dead corner area of ​​the tripod, and can effectively prevent secondary pollution. Compared with traditional manual cleaning, disassembly is avoided, time and labor are saved, and the cleaning effect is better, and automation is achieved. The specific improvements are as follows:

[0071] As an embodiment, the present invention provides a washing device. Figure 1 and Figure 2 As shown, the washing device comprises a rotatable inner drum 100 for washing clothes.

[0072] A tripod 200 is provided at the bottom of the inner drum 100 for rubbing clothes to help improve the washing effect.

[0073] The tripod 200 includes a plurality of arms 220 , one end of each arm 220 is fixedly connected, and the other end of each arm 220 is spaced apart along the circumference of the inner tube 100 .

[0074] like Figure 2 As shown, specifically, the tripod 200 includes a tripod shaft 210 and three arms 220, one end of the three arms 220 is fixedly connected, and the other end is arranged at intervals along the circumference of the inner cylinder 100, and there is a certain angle between the arms 220. The slope of the arms 220 can be set as required to make its shape prominent and can rub the clothes; a through hole is provided at the center position of the bottom wall of the inner cylinder 100, and the tripod shaft 210 is penetrated by the through hole and sealed with the through hole, and the tripod shaft 210 is connected to a power device, and the power device drives the tripod 200 and the inner cylinder 100 to rotate synchronously.

[0075] Preferably, a seal 400 is installed between the through hole and the tripod shaft 210 to achieve a sealed connection therebetween. The seal 400 is a bearing seat, a rubber sleeve, etc., which can ensure that the through hole and the tripod shaft 210 can rotate relative to each other while also ensuring that the seal is watertight.

[0076] The device also includes a dirtiness detection device for detecting the dirtiness of the surface of the tripod 200 .

[0077] The turbidity detection device includes a light transmittance sensor, which is disposed on the surface of the tripod 200 and is used to detect the light transmittance of the surface of the tripod 200 .

[0078] The light transmittance is the ratio of the actual light received amount to the total light amount; wherein the total light amount is the amount of light emitted by the light source of the light transmission sensor.

[0079] In this embodiment, it is preferred to install a light transmission sensor on the entire surface of the three arms 220 of the tripod 200, and obtain the light transmittance by scanning the entire arm surface of the three arms 220 with light. The light transmission sensor can detect the light transmittance of the surface of the tripod 200 in real time.

[0080] The device further comprises a spray cleaning module 500 rotatably disposed at the bottom of the inner cylinder 100 for spray cleaning the surface of the tripod 200 .

[0081] The spray cleaning module 500 is rotatably mounted on the bottom wall of the inner cylinder 100 and is located at the interval between the support arms 220. The spray cleaning module 500 can rotate 360°.

[0082] By setting the spray cleaning module 500 at the interval of the support arm 220, the spray cleaning module 500 is located on the side of the tripod 200, so that the outer surface of the tripod 200 can be cleaned; and the spray cleaning module 500 is set to be rotatable 360°, so that the spray cleaning module 500 can perform all-round spray cleaning on the outer surface of the tripod 200, thereby achieving cleaning of the tripod 200 without dead ends.

[0083] The bottom wall of the inner cylinder 100 corresponding to the spray cleaning module 500 is recessed toward the bottom of the inner cylinder 100 , so that the height of the spray cleaning module 500 protruding from the bottom wall of the inner cylinder 100 is less than the height of the tripod 200 .

[0084] The spray cleaning module 500 is recessed on the bottom wall of the inner drum 100 to ensure that the spray cleaning module 500 can spray to the junction of the tripod 200 and the bottom wall of the inner drum 100, because this is a dead corner and it is easy for dirt to accumulate, so as to avoid secondary pollution caused by the dirt in the dead corner not being cleaned thoroughly; at the same time, it is also to prevent the spray cleaning module 500 from occupying the washing space in the inner drum 100, so as to ensure the smooth execution of the washing process.

[0085] It also includes a liquid inlet module, which is connected to the spray cleaning module 500 and is used to provide cleaning liquid to the spray cleaning module 500.

[0086] The spray cleaning module 500 is provided with a spray hole, and the spray hole is used to spray cleaning liquid onto the surface of the tripod 200 .

[0087] In this embodiment, the liquid inlet module includes a water inlet assembly, a distributor box and a liquid inlet pipe, and the liquid inlet pipe is respectively connected to the distributor box and the spray cleaning module 500. When the spray cleaning module 500 is required to work, the water inlet assembly feeds water into the distributor box, dissolves the cleaning agent in the distributor box and flushes it into the liquid inlet pipe, and then transports it to the spray cleaning module 500 through the liquid inlet pipe and sprays it out from the spray hole.

[0088] The interior of the tripod shaft 210 is hollow, and the bottom wall of the inner tube 100 is provided with a cavity. The interior of the tripod shaft 210 is connected with the cavity and the spray cleaning module 500 to form a liquid inlet channel. The liquid inlet pipe provides cleaning liquid to the spray cleaning module 500 through the liquid inlet channel.

[0089] The cleaning liquid can be a mixture of detergent or other cleaning agents with strong decontamination ability and water. It should be noted that the cleaning agent will not damage the washing equipment and clothes. A chamber specifically for accommodating the cleaning agent can be set in the dispenser box.

[0090] Furthermore, it also includes a driving member connected to the spray cleaning module 500 and used to drive the spray cleaning module 500 to rotate, and the rotation angle of the spray cleaning module 500 is adjustable.

[0091] The rotation angle of the spray cleaning module 500 is adjustable, which can not only make the spray cleaning liquid cover the entire outer surface of the tripod 200, but also spray the cleaning liquid onto the inner surface of the inner cylinder 100, thereby increasing the coverage area of ​​the spray cleaning, achieving a better cleaning effect on both the tripod 200 and the inner cylinder 100 and improving the cleanliness.

[0092] Furthermore, it also includes a pressurizing member, which is connected to the liquid inlet module and the spray cleaning module 500, and is used to increase the spray pressure, increase the spray range and spray coverage area of ​​the cleaning liquid sprayed from the spray hole, and increase the impact force of the cleaning liquid on the surface of the tripod 200 and / or the surface of the inner tube 100, which can further help improve the cleaning effect of dirt.

[0093] The smooth transition setting of the surface of the spray cleaning module 500 can not only prevent the spray cleaning module 500 from scratching clothes, but also the smooth transition surface is equivalent to a stirring rib, which can contact and collide with clothes to assist in washing the clothes.

[0094] It also includes an ultrasonic cleaning module, which is arranged at the fixed connection of the support arm 220 and includes:

[0095] An ultrasonic generator 300, used to emit a high-frequency vibration signal;

[0096] The transducer is used to convert the high-frequency vibration signal into the mechanical vibration of the tripod 200 and the inner cylinder 100.

[0097] By arranging the ultrasonic cleaning module at the fixed connection of the support arm 220, it is convenient to convert the high-frequency vibration signal emitted by the ultrasonic generator 300 into the mechanical vibration of the entire tripod 200 and the inner cylinder 100, and vibrate the dirt on the tripod 200 and the inner cylinder 100, especially the dirt in the dead corners, to achieve cleaning without dead corners.

[0098] Preferably, a groove is provided at the connection of the three arms 220, and the ultrasonic generator 300 is installed in the groove, so that the surface of the tripod 200 still has a smooth transition, avoiding the protruding setting of the ultrasonic generator 300 to have an adverse effect on the washed clothes; the transducer can be installed on the inner drum 100, and can also be installed on the tripod 200, and can be arranged according to needs.

[0099] When the transmittance detected by the light transmittance sensor is less than the preset transmittance, the spray cleaning module 500 and the ultrasonic cleaning module start working in sequence. Through the cooperation of the two, the blind spots of the tripod 200 can be cleaned very well, and secondary pollution can be effectively prevented. Compared with traditional manual cleaning, disassembly is avoided, time and labor are saved, and the cleaning effect is better.

[0100] Preferably, before the ultrasonic cleaning module works, washing water of a preset water level is injected into the inner drum 100. In this way, the spray cleaning module 500 first rotates and sprays the cleaning liquid, the cleaning liquid contains a cleaning agent, which has the effects of softening and decomposing dirt. The dirt is first soaked with the cleaning liquid, and then the washing water of a preset water level is injected into the inner drum 100. Then the ultrasonic cleaning module is turned on, and the ultrasonic generator 300 sends a high-frequency vibration signal, and the high-frequency vibration signal is converted into a mechanical vibration of the inner drum 100 and the tripod 200 by a transducer, and transmitted to the water. The bubbles generated by the cleaning liquid, under the action of mechanical vibration, the bubbles suspended in the liquid will vibrate irregularly and generate shock waves. The inner drum 100 also vibrates synchronously, resonating with the shock waves in the water, and the dirt on the tripod 200 and the inner drum 100, as well as the dirt in the dead corners, are quickly vibrated off and discharged with the water, which can effectively save cleaning time and improve the cleaning effect.

[0101] It should be noted that during the spray cleaning and ultrasonic cleaning process, the inner drum 100 can be in a rotating state or a stationary state. It is preferably carried out in a stationary state of the inner drum 100 and alternately with the rotation of the inner drum 100; the washing water to a preset water level can also be injected into the inner drum 100 after the spray cleaning and ultrasonic cleaning.

[0102] As an embodiment, the present invention provides a method for cleaning an inner cylinder tripod, such as Figure 3 As shown, the method comprises the following steps:

[0103] S1: Detect the light transmittance of the tripod surface;

[0104] S2: determining that the light transmittance is less than a preset light transmittance;

[0105] S3: Execute the cleaning procedure of the tripod;

[0106] S4: Turn on the spray cleaning module and spray the cleaning liquid while rotating;

[0107] S5: Turn on the ultrasonic cleaning module to perform ultrasonic cleaning;

[0108] S6: Check whether the cleaning of the tripod meets the preset requirements;

[0109] S7: End the cleaning process.

[0110] When the transmittance is less than the preset transmittance, it indicates that the surface of the tripod is highly dirty, i.e., it is judged that the inner tube of the tripod needs to be cleaned; first, the cleaning module is rotated and sprayed with cleaning liquid, wherein the cleaning liquid contains a cleaning agent, which has the effects of softening and decomposing the dirt. The dirt is first soaked with the cleaning liquid, and then the ultrasonic cleaning module is turned on, which can quickly shake off the stubborn dirt with ultrasonic vibration, effectively saving cleaning time and improving the cleaning effect.

[0111] As an embodiment, the present invention provides a method for cleaning an inner cylinder tripod, such as Figure 4 As shown, the method comprises the following steps:

[0112] S1: Detect the light transmittance of the tripod surface;

[0113] S2: determining that the light transmittance is less than a preset light transmittance;

[0114] S3: Execute the cleaning procedure of the tripod;

[0115] S4: Turn on the spray cleaning module and spray the cleaning liquid while rotating;

[0116] S5: Fill water into the inner cylinder to a preset water level;

[0117] S6: Control the ultrasonic generator to start up to emit a high-frequency vibration signal, and control the transducer to start up to convert the high-frequency vibration signal into mechanical vibration of the tripod and the inner cylinder;

[0118] S7: discharge washing water;

[0119] S8: Check whether the cleaning of the tripod meets the preset requirements;

[0120] S9: End the cleaning process.

[0121] Between step S5 and step S6, the process further includes: controlling the inner drum to rotate at least one time. By controlling the inner drum to rotate, water is used to preliminarily clean the dirt in the area where the cleaning liquid is immersed. At the same time, part of the cleaning liquid enters the water, so that bubbles are generated in the cleaning liquid during subsequent ultrasound and irregular vibrations are performed to generate shock waves, which resonate with the vibration of the inner drum and quickly vibrate the dirt in the dead corners.

[0122] It should be noted that in step S5, the process of injecting water into the inner drum to a preset water level can also be after spray cleaning and ultrasonic cleaning. The preset water level is a low water level, which cooperates with the rotation of the inner drum to clean the dirt.

[0123] Step S6 also includes controlling the inner drum to stop rotating, turning on the ultrasonic cleaning module for ultrasonic cleaning, turning off the ultrasonic cleaning module when the ultrasonic time reaches a preset time, controlling the inner drum to rotate at a preset angle and then stop rotating, turning on the ultrasonic cleaning module, and so on, the inner drum rotation and the ultrasonic cleaning module are performed alternately until the total ultrasonic time reaches the preset ultrasonic time.

[0124] The preset angle is less than or equal to 180°, preferably 20-90°, and more preferably 30°.

[0125] Within the preset ultrasonic time, the inner drum rotates at least one circle, so that every part of the inner drum is soaked in water during ultrasound, forming resonance during ultrasound, and quickly vibrating and removing dirt in dead corners; at the same time, the inner drum rotates, causing the water flow to fluctuate, which also has a flushing effect on the dirt.

[0126] In step S8, detecting whether the cleaning of the tripod meets the preset requirements includes: detecting the real-time light transmittance of the surface of the tripod during the cleaning process; obtaining the change rate of the light transmittance; and determining that the change rate is less than a preset change rate.

[0127] And / or, detecting the real-time light transmittance of the tripod surface during the cleaning process; and determining whether the real-time light transmittance is greater than or equal to a preset light transmittance.

[0128] And / or, detecting that the ultrasound time reaches a preset ultrasound time.

[0129] It should be noted that the present invention uses the rate of change of transmittance less than the preset rate of change, the real-time transmittance greater than or equal to the preset transmittance, and the ultrasonic time reaching the preset ultrasonic time as the standard for judging that the dirt on the tripod has been basically cleaned and has met the preset cleaning requirements. The above judgment conditions can be used as a single judgment standard, or the above judgment conditions can be combined as a comprehensive judgment standard. It can be set as needed to improve the accuracy of the judgment.
