Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to an ultrasonic cleaning method and clothing treatment equipment. Background Technology

[0002] Ultrasonic cleaning is a classic cleaning method, especially suitable for dirt adhering to hard materials. In daily life, ultrasonic cleaning is also widely used to clean various everyday items such as glasses, jewelry, and dentures.

[0003] When using ultrasonic cleaning to clean items with large surface areas, such as eyeglasses, water droplets easily form on the surface due to the surface tension of water, affecting visual clarity. Users need to manually wipe the glasses after ultrasonic cleaning, increasing their workload and burden. Using air drying or oven drying to remove the water droplets not only increases costs, but also leaves behind calcium and magnesium ions as carbonate and bicarbonate precipitates after evaporation, forming water stains that also severely affect lens clarity. Wiping the glasses under these conditions can easily scratch the lenses. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic cleaning method and clothing treatment equipment that can solve the problem of residual water droplets on lenses after ultrasonic cleaning.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An ultrasonic cleaning method involves injecting a cleaning agent and water into a cleaning chamber after the cleaning phase, immersing the object to be cleaned in a solution of water and the cleaning agent, and then draining the water for the last time.

[0007] As an alternative to the above-mentioned ultrasonic cleaning method, during the final drainage, the rate at which the liquid level in the cleaning chamber decreases is less than or equal to 15 mm / s.

[0008] As an alternative to the above-mentioned ultrasonic cleaning method, siphon drainage is used during the final drainage.

[0009] As an alternative to the above ultrasonic cleaning method, the process prior to the cleaning stage includes:

[0010] A solution of atomized cleaning agent and water is used to wet the object to be cleaned.

[0011] As an alternative to the above-mentioned ultrasonic cleaning method, the mixture of atomizing cleaning agent and water comprises:

[0012] Inject cleaning agent and water into the cleaning chamber;

[0013] Turn on the ultrasonic generator to atomize.

[0014] As an optional embodiment of the above-mentioned ultrasonic cleaning method, the cleaning stage includes:

[0015] Start the ultrasonic generator to perform ultrasonic cleaning;

[0016] Start the overflow drainage to allow the water in the cleaning chamber to overflow and be discharged from the top.

[0017] As an optional solution to the above ultrasonic cleaning method, initiating overflow drainage includes:

[0018] Water is injected into the cleaning chamber to make the water level in the cleaning chamber higher than the preset overflow water level, so as to achieve overflow drainage;

[0019] And / or, adjust the power or frequency of the ultrasonic generator to cause the liquid level in the cleaning chamber to oscillate and exceed the preset overflow level.

[0020] As an optional embodiment of the above-mentioned ultrasonic cleaning method, the cleaning stage further includes:

[0021] Water is injected into the cleaning chamber to bring the water level in the cleaning chamber to the siphon level, thereby activating the siphon drainage. The siphon level is higher than the preset overflow level.

[0022] As an alternative to the above-mentioned ultrasonic cleaning method, during the cleaning stage, water is injected into the cleaning chamber from the bottom of the cleaning chamber.

[0023] As an optional embodiment of the above-mentioned ultrasonic cleaning method, injecting water into the cleaning chamber includes:

[0024] The injected water flows spirally upward from the bottom of the cleaning chamber.

[0025] As an alternative to the above-mentioned ultrasonic cleaning method, overflow drainage is initiated during the operation of the ultrasonic generator.

[0026] Alternatively, after the ultrasonic generator is turned off, the overflow drainage is activated.

[0027] As an alternative to the above-mentioned ultrasonic cleaning method, during the overflow drainage process, gas or water is blown from the bottom center of the cleaning chamber to the top so that the center liquid level of the solution surface in the cleaning chamber is higher than the outer liquid level.

[0028] A garment processing device, comprising:

[0029] Organism;

[0030] An ultrasonic cleaning mechanism is installed in the machine body;

[0031] A control component, electrically connected to the ultrasonic cleaning mechanism, is used to perform the ultrasonic cleaning method described above.

[0032] The beneficial effects of this invention are:

[0033] In the ultrasonic cleaning method provided by the present invention, water and cleaning agent are injected into the cleaning chamber after the cleaning stage is completed. The cleaning agent is used to reduce the surface tension of the water, so that the water is less likely to form water droplets on the surface of the object to be cleaned. This avoids water droplets remaining on the surface of the object to be cleaned after drainage, and thus eliminates the need for manual wiping after cleaning. This reduces the user's operation and also avoids the object to be cleaned being scratched by water stains and other impurities during wiping.

[0034] The clothing processing equipment provided by the present invention uses the above-mentioned ultrasonic cleaning method, which can avoid water droplets remaining on the surface of the item to be cleaned. Attached Figure Description

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0045] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0048] Example 1

[0049] This embodiment provides an ultrasonic cleaning method that can be applied to equipment with ultrasonic cleaning function and can be used to clean items such as jewelry and eyeglasses.

[0050] like Figure 1As shown, after the ultrasonic cleaning stage, water and cleaning agent are injected into the cleaning chamber containing the object to be cleaned, immersing the object in the solution. A final drainage is then performed. By injecting cleaning agent into the water before the final drainage, the surface tension of the water is reduced, making it less likely for water droplets to form on the surface of the object. This avoids water droplets remaining on the surface after drainage, eliminating the need for manual wiping. This reduces user workload and prevents scratches caused by water stains or other impurities during wiping.

[0051] Alternatively, the cleaning agent can be an additive containing surfactants, such as laundry detergent, laundry powder, dish soap, or eyeglass cleaning solution.

[0052] Optionally, the cleaning agent can be added during the process of injecting water into the cleaning chamber, or it can be added separately before or after water injection; this embodiment does not impose any restrictions.

[0053] In some embodiments, before the final drainage, the liquid level in the cleaning chamber can be detected to determine whether the liquid level has reached a first preset level. If it has, water injection is stopped. These steps ensure that the solution completely submerges the object to be cleaned, guaranteeing that no water droplets remain on any surface of the object, thus improving the cleaning effect.

[0054] In some embodiments, the first preset liquid level can be a fixed value. The height of the first preset liquid level is greater than the height of common items, such as the height of eyeglass lenses, so as to ensure that common items can be submerged in the solution when placed in the cleaning chamber.

[0055] Optionally, the height of the first preset liquid level is 30mm-60mm, preferably 40mm-50mm. Within this range, it can ensure that most of the items being cleaned are submerged while reducing water consumption and avoiding water waste.

[0056] For example, the height of the first preset liquid level is 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, or 60mm.

[0057] In some other embodiments, the first preset liquid level can be determined based on the actual height of the object to be cleaned. Specifically, before injecting water into the cleaning chamber, the height information of the object to be cleaned in the cleaning chamber is obtained. Based on this height information, the corresponding first preset liquid level is obtained. When the liquid level in the cleaning chamber reaches the first preset liquid level, water injection is stopped. It is understood that the height of the first preset liquid level is greater than the obtained height of the object to be cleaned.

[0058] Optionally, the height information of the object to be cleaned can be obtained by acquiring image information inside the cleaning chamber, and the corresponding first preset liquid level can be obtained by pre-storing a database containing the correspondence between height and liquid level.

[0059] Example 2

[0060] This embodiment provides an ultrasonic cleaning method, which is a further improvement on the first embodiment.

[0061] To avoid water droplets remaining on the surface of the object to be cleaned, the drainage rate of the cleaning chamber is controlled during the final drainage, allowing the liquid level in the cleaning chamber to drop slowly. Because the surface tension of water decreases under the influence of the added cleaning agent, water droplets are less likely to form on the surface of the object. Even if water droplets might form in some areas during slow drainage, the surface tension of the slowly decreasing water will pull these droplets away with the water level, thus preventing water droplets from remaining on the eyeglasses surface.

[0062] In some embodiments, during the final drainage, the rate of liquid level drop in the cleaning chamber is less than or equal to 15 mm / s, and preferably 3 mm / s to 8 mm / s. Within this range, it can be ensured that no water droplets remain on the surface of the object to be cleaned, thus eliminating the need for manual wiping, preventing water stains from remaining on the surface after the object dries, and also ensuring drainage speed and shortening drainage time.

[0063] It should be noted here that the rate of decrease of the liquid level in the cleaning chamber is the height by which the liquid level in the cleaning chamber decreases per unit time.

[0064] For example, typical non-limiting values ​​for the rate of decrease of the liquid level in the cleaning chamber are 1 mm / s, 2 mm / s, 3 mm / s, 4 mm / s, 5 mm / s, 6 mm / s, 7 mm / s, 8 mm / s, 9 mm / s, 10 mm / s, 11 mm / s, 12 mm / s, 13 mm / s, 14 mm / s, and 15 mm / s.

[0065] For example, when the liquid level in the cleaning chamber decreases at a rate of 3 mm / s, combined with Figure 7 As shown, the solution in the cleaning chamber drops from level A to level B in just 1 second, and the height difference H between level A and level B is 3 mm.

[0066] Based on a liquid level drop rate of 3 mm / s in the cleaning chamber, the solution in the cleaning chamber can generally be drained within 20 seconds when the object to be cleaned is sunglasses; when the object to be cleaned is ordinary eyeglasses, the solution in the cleaning chamber can generally be drained within 15 seconds.

[0067] To improve the stability of the liquid level drop rate, in some embodiments, such as Figure 2As shown, siphon drainage can be used for the final drainage. Siphon drainage utilizes the intermolecular attraction and potential energy of liquid molecules. That is, it uses the pressure difference of the water column to cause the water to rise first and then flow to a lower position. Siphon drainage has a stable drainage speed, which helps to evenly lower the liquid level in the cleaning chamber, thus avoiding water droplet residue. Siphon drainage also improves the cleaning effect, preventing residual water in the cleaning chamber. Compared to pump pumping, siphon drainage is more stable and quieter because it does not involve motor vibration and is less prone to water droplet formation.

[0068] Specifically, a siphon drainage channel is provided to achieve siphon drainage. The siphon drainage channel extends upward from the bottom of the cleaning chamber and then downward, so as to form a siphon inflection point at the position where the extension direction changes, thereby realizing siphon drainage.

[0069] Optionally, the rate of decrease in the liquid level within the cleaning chamber can be controlled by adjusting the flow area of ​​the siphon drainage channel. It is understood that the smaller the flow area of ​​the siphon drainage channel, the slower the rate of decrease in the liquid level within the cleaning chamber. When the flow area of ​​the siphon drainage channel remains constant, the rate of decrease in the liquid level within the cleaning chamber remains unchanged.

[0070] In other embodiments, drainage can be achieved by pumping or valves, and the drainage rate can be controlled by flow regulators (such as flow control valves or flow meters) to achieve slow and stable drainage.

[0071] In some embodiments, the cross-sectional area of ​​the cleaning chamber can be set as large as possible. With the drainage flow rate remaining constant, the larger the cross-sectional area of ​​the cleaning chamber, the slower the liquid level in the cleaning chamber drops, which helps to avoid water droplets remaining on the surface of the object to be cleaned.

[0072] In some embodiments, after the solution in the cleaning chamber is drained, a cleaning completion reminder program is executed to remind the user to remove the item to be cleaned.

[0073] Optionally, the cleaning completion reminder program can notify the user that the cleaning is complete through at least one of the following methods: speaker, vibration, and screen display.

[0074] Example 3

[0075] This embodiment provides an ultrasonic cleaning method, which is a further improvement on Embodiment 1 or Embodiment 2.

[0076] In this embodiment, the ultrasonic cleaning method further includes an immersion stage, which is located before the cleaning stage. The object to be cleaned passes through the immersion stage and the cleaning stage in sequence, which helps to improve the cleaning effect.

[0077] Specifically, such as Figure 3As shown, during the immersion stage, the solution of atomized cleaning agent and water is used to wet the surface of the object to be cleaned through atomized particles of the solution. It can be understood that the atomized solution forms atomized particles that float within the cleaning chamber, allowing for rapid and thorough diffusion, thus completely enveloping the object to be cleaned, softening the dirt on the surface, and enhancing the cleaning effect in conjunction with the cleaning stage.

[0078] In some embodiments, the immersion stage specifically involves injecting cleaning agent and water into the cleaning chamber to mix them into a solution. Then, an ultrasonic generator is activated, using the vibration of the ultrasonic waves to atomize the solution. This method does not require an additional atomizing structure and does not increase costs.

[0079] By atomizing water containing cleaning agent, the resulting atomized particles contain cleaning agent components, improving the wetting effect on the object to be cleaned and thus enhancing the final cleaning effect.

[0080] During the immersion phase, the liquid level in the cleaning chamber is at the second preset level, which is lower than the first preset level. During the immersion phase, the solution does not need to completely submerge the object to be cleaned. This reduces the amount of water used and increases the proportion of cleaning agent in the solution, allowing it to better act on the stains on the surface of the object during immersion, thereby improving the cleaning effect.

[0081] In some embodiments, the second preset liquid level is a fixed preset liquid level, sufficient to ensure a certain amount of atomization. In other embodiments, the second preset liquid level can also be a value set by the user to better meet the user's personalized usage needs.

[0082] In some embodiments, the atomization time during the immersion stage can be a fixed set duration to ensure atomization effect. It should be noted that the atomization time refers to the working time for generating atomized particles through the operation of an ultrasonic generator or other structure.

[0083] Optionally, the atomization time can be 20s-90s, preferably 30s-60s, to ensure that the atomized particles are fully diffused in the cleaning chamber and to ensure the encapsulation of the object to be cleaned.

[0084] For example, the atomization duration is 20s, 25s, 30s, 35s, 40s, 45s, 50s, 55s, 60s, 65s, 70s, 75s, 80s, 85s, and 90s.

[0085] In some other embodiments, the atomization time can be determined based on information about the actual object to be cleaned. Optionally, before atomization, information about the object to be cleaned in the cleaning chamber is obtained, including at least one of the following: quantity, size, material, and degree of dirtiness of the object; and the corresponding atomization time is obtained based on the obtained information about the object to be cleaned.

[0086] Alternatively, the information about the object to be cleaned can be obtained through at least one of image acquisition, weighing, and information interaction with the user.

[0087] In some embodiments, during the atomization process, the frequency and power of the ultrasonic generator can be determined based on the information of the object to be cleaned in order to improve the atomization effect.

[0088] Understandably, the higher the frequency of the ultrasonic generator, the stronger the ultrasonic energy, and the better the atomization effect; similarly, the higher the power of the ultrasonic generator, the stronger the ultrasonic energy, and the better the corresponding atomization effect.

[0089] In some other embodiments, atomization can be achieved through an atomizing nozzle. The solution of spray water and cleaning agent is atomized after passing through the atomizing nozzle, and the atomized particles are sprayed into the cleaning chamber, which can also wet the object to be cleaned by atomization.

[0090] In some embodiments, after atomization, the particles are allowed to stand for a preset interval before entering the cleaning stage. By allowing them to stand for a period of time, sufficient contact between the atomized particles and the object to be cleaned can be ensured, thereby guaranteeing the wetting effect of the atomized particles on the object to be cleaned and improving the final cleaning effect.

[0091] Optionally, the preset interval is 1 second to 30 seconds, preferably 10 seconds, to ensure the wetting effect while avoiding affecting the total cleaning time and ensuring cleaning efficiency.

[0092] For example, typical non-limiting values ​​for the preset interval duration are 1 second, 5 seconds, 10 seconds, 15 seconds, 20 seconds, 25 seconds, and 30 seconds.

[0093] Understandably, when there are no stubborn stains on the surface of the glasses, the cleaning stage and the final rinse are sufficient to ensure the cleaning effect. When there is a lot of dirt on the glasses or there are stubborn stains, the soaking stage can be activated to improve the cleaning effect.

[0094] In some embodiments, a confirmation process for initiating the immersion phase is included before starting the immersion phase. In other words, the immersion phase can be selectively initiated as needed to achieve energy savings while ensuring effective cleaning.

[0095] In some embodiments, confirming whether to start the immersion phase can first involve executing a confirmation reminder program, which can interact with the user through at least one of voice or text display methods; then, the user's instruction information is obtained, and the immersion phase is enabled or disabled based on the user's instruction information to better meet the user's needs.

[0096] Optionally, user instructions can be obtained through buttons, knobs, touchscreens, or voice commands.

[0097] In some embodiments, if no user instruction information is obtained after the confirmation reminder procedure is executed and a preset waiting time is not followed, the immersion phase is not started by default.

[0098] In some other embodiments, determining whether to initiate the immersion phase can be done by obtaining the degree of dirtiness of the glasses. For example, image information of the glasses is obtained to determine the degree of dirtiness; if the degree of dirtiness is greater than a preset dirtiness value, the immersion phase is initiated; otherwise, the immersion phase is not initiated.

[0099] Example 4

[0100] This embodiment provides an ultrasonic cleaning method, which is a further improvement on any of the above embodiments.

[0101] In this embodiment, as Figure 4 As shown, the ultrasonic cleaning method includes a cleaning stage, in which the object to be cleaned, contained in a solution, is cleaned using ultrasonic waves. The solution can be water or a mixture of a cleaning agent and water.

[0102] After the ultrasonic generator is turned on, it produces ultrasonic waves, which transmit the oscillation energy of the waves through the solution to the object to be cleaned. The cavitation effect of the ultrasonic waves generates a large number of microbubbles. When these microbubbles burst, they remove stains, grease, sebum, and other dirt from the surface of the object, achieving the cleaning purpose. However, because the dirt has a low density, it floats on the surface of the solution. As the water is drained after washing, the dirt re-adheres to the surface of the object, resulting in a poor cleaning effect.

[0103] To address the aforementioned issues, this embodiment employs overflow drainage during the cleaning phase. Overflow drainage refers to discharging the solution within the cleaning chamber through a top overflow. During overflow drainage, any dirt floating on the solution surface is flushed out with the overflow, preventing it from re-adhering to the surface of the object to be cleaned.

[0104] After the overflow drainage has been running for a period of time, drain the remaining water from the cleaning chamber to complete the cleaning process.

[0105] It should be noted that the cleaning chamber is connected to an overflow port, which has a certain height. During overflow drainage, the solution surface level is always within the height range covered by the overflow port. In other words, during overflow drainage, the liquid level in the cleaning chamber must not exceed the overflow port to ensure that dirt on the solution surface can always be discharged through the overflow port.

[0106] To achieve overflow drainage, in some embodiments, overflow drainage specifically includes injecting water into the cleaning chamber to make the liquid level in the cleaning chamber higher than a preset overflow level, thereby achieving overflow drainage.

[0107] To prevent the dirt floating on the solution surface from sinking during the water injection process, in some embodiments, water is injected into the cleaning chamber from the bottom during overflow drainage. This reduces the impact of the injected water flow on the dirt on the top of the solution, thereby preventing the dirt from sinking and allowing the dirt on the solution surface to overflow and be discharged.

[0108] To improve the removal of dirt, in some embodiments, when water is injected into the cleaning chamber during the cleaning phase, the injected water flows spirally upward from the bottom of the cleaning chamber. This water injection method allows dirt floating or suspended in the solution to move away from the object to be cleaned, and float on the surface of the solution with the rising water flow, flowing towards the edge of the cleaning chamber, thereby facilitating the removal of dirt.

[0109] To achieve the aforementioned flow pattern, water inlets are provided on both opposite sides of the cleaning chamber, with the inlets staggered and located close to the edge of the cleaning chamber. When water is injected into the cleaning chamber through the two inlets, it guides the water flow along the circumference of the cleaning chamber, thereby forming a spiral upward water flow.

[0110] To automatically drain the remaining water from the cleaning chamber after a period of overflow drainage, in some embodiments, water continues to be injected into the cleaning chamber after the overflow drainage is activated, raising the liquid level in the cleaning chamber to the siphon level, which is higher than the preset overflow level. By raising the liquid level in the cleaning chamber to the siphon level, the siphon drainage is activated, thereby automatically draining the water from the cleaning chamber.

[0111] It should be noted that the siphon drainage has a siphon channel that extends upwards and then downwards to form a channel inflection point. The height of the siphon water level is greater than or equal to the height of the channel inflection point, so that the siphon drainage can be automatically activated after the water level in the cleaning chamber rises to the siphon water level, which simplifies the control logic and structure and thus reduces costs.

[0112] When overflow drainage is achieved by injecting water into the cleaning chamber, the overflow drainage can be initiated after the ultrasonic cleaning is completed. That is, during the cleaning phase, the ultrasonic generator is started first, and after the ultrasonic generator operates for a first preset time, the ultrasonic generator is turned off; then, water is injected into the cleaning chamber, the overflow drainage is initiated, and continues for a second preset time.

[0113] In some other embodiments, overflow drainage can be initiated during the ultrasonic cleaning process. Optionally, water is injected into the cleaning chamber to activate overflow drainage after the ultrasonic generator has been operating for a third preset time. The third preset time is shorter than the first preset time. In other words, overflow drainage is activated after a period of ultrasonic cleaning.

[0114] In some other embodiments, during the cleaning phase, water is first injected into the cleaning chamber to reach a preset overflow level. At the same time or after the overflow drainage is started, the ultrasonic generator is activated to begin ultrasonic cleaning.

[0115] Optionally, after ultrasonic cleaning is completed, that is, after the ultrasonic generator is turned off, overflow drainage continues for a period of time to ensure the effective removal of dirt.

[0116] In some embodiments, the first preset duration is a preset fixed duration, or the first preset duration is determined based on the information of the object to be cleaned. The information of the object to be cleaned includes at least one of the quantity, size, material, and degree of dirtiness of the object to be cleaned. It is understood that the more objects to be cleaned, the larger their size, and the more serious the degree of dirtiness, the longer the first preset duration will be, so as to ensure the cleaning effect.

[0117] In some embodiments, the second preset duration can be determined based on the dirt floating on the solution surface or based on the information of the object to be cleaned, so as to ensure that all dirt can be discharged by overflow and reduce the probability of dirt adhering to the surface of the object to be cleaned again.

[0118] Alternatively, the information about the object to be cleaned can be obtained through at least one of image acquisition, weighing, and information interaction with the user.

[0119] In some other embodiments, the first preset duration and the second preset duration can be determined by user settings.

[0120] In some other embodiments, overflow drainage is achieved by adjusting the power or frequency of the ultrasonic generator to cause the solution in the cleaning chamber to oscillate above a preset overflow level.

[0121] Specifically, during ultrasonic cleaning, the ultrasonic waves generated by the ultrasonic generator act on the solution, causing it to vibrate and ripple, resulting in surface fluctuations. By controlling the frequency or power of the ultrasonic generator, the amplitude of these fluctuations can be controlled, allowing the solution to rise to a preset overflow level and achieve overflow.

[0122] In this method, the overflow occurs while the ultrasonic generator is working; that is, ultrasonic cleaning is performed to drain water outwards through the overflow direction to remove dirt.

[0123] To ensure overflow via ultrasound, the liquid level in the cleaning chamber can be raised to a preset overflow level before ultrasonic cleaning to initiate overflow. Then, the power or frequency of the ultrasonic generator is adjusted to control the fluctuation of the solution, ensuring continuous overflow for a specified period.

[0124] Understandably, without adding water to the cleaning chamber, the power and / or frequency of the ultrasonic generator gradually increase as the overflow time increases to ensure that overflow can be achieved.

[0125] To ensure cleaning effectiveness, in some embodiments, the cleaning stage can be repeated a preset number of times to avoid wasting resources and improve cleaning results.

[0126] Optionally, the preset number of times can be a fixed value, such as 2-5 times, for example, 2 times, 3 times, 4 times, or 5 times, to control the cleaning time while ensuring the cleaning effect. Specifically, after the solution in the cleaning chamber is drained, the number of times is accumulated, and it is determined whether the accumulated number of times has reached the preset number. If not, the cleaning stage is repeated; if it has reached the preset number, the cleaning stage is completed.

[0127] Optionally, the number of times the cleaning phase is executed can be set according to the turbidity of the solution in the cleaning chamber before overflow drainage. Before overflow drainage, the turbidity of the solution in the cleaning chamber is detected. If the turbidity is greater than a preset difference, the cleaning phase is continued after the current overflow drainage is completed, thereby ensuring the cleaning effect while avoiding resource waste.

[0128] In some embodiments, the preset number of cleaning stages includes a main wash and a rinse. During both the main wash and the rinse, an ultrasonic generator and overflow drainage are activated. The difference is that the solution in the cleaning chamber during the main wash is a mixture of water and cleaning agent, while the solution in the cleaning chamber during the rinse is water without cleaning agent, in order to achieve the rinsing effect.

[0129] To improve cleaning effectiveness, the ultrasonic cleaning method may optionally include at least one main cleaning stage and at least one rinsing stage.

[0130] For example, in the preset number of cleaning stages, the first cleaning stage is the main wash, and the remaining cleaning stages are all rinsing.

[0131] Example 5

[0132] This embodiment provides an ultrasonic cleaning method, which is a further improvement on Embodiment 4.

[0133] To ensure that the dirt floating on the solution surface can be discharged smoothly through overflow, in this embodiment, during the overflow drainage process, gas or water is blown in from the bottom center of the cleaning chamber to the top, so that the central liquid level of the solution surface in the cleaning chamber is higher than the peripheral liquid level. As a result, the solution on the surface tends to flow from the center to the periphery, so that the solution surface in the cleaning chamber forms a water surface that gradually decreases from the center to the periphery, thereby allowing the dirt floating on the solution surface to be discharged through the overflow outlet set in the periphery.

[0134] Example 6

[0135] This embodiment provides an ultrasonic cleaning method that can be used to clean eyeglasses and prevent water droplets from remaining on them. In this embodiment, eyeglasses are used as the object to be cleaned.

[0136] like Figure 5 As shown, the ultrasonic cleaning method specifically includes:

[0137] S1: Confirm that the glasses are placed in the cleaning chamber and the lenses are roughly upright.

[0138] Optionally, the glasses can be folded or unfolded and placed into the cleaning chamber as needed.

[0139] Optionally, the correct placement of the glasses can be confirmed by acquiring image information from inside the cleaning chamber, and if the placement is incorrect, the user can be alerted to adjust the glasses via at least one of a speaker, vibration, and screen display.

[0140] S2: Inject cleaning agent and water into the cleaning chamber so that the solution after mixing the cleaning agent and water reaches the second preset liquid level.

[0141] The second preset liquid level does not need to cover the goggles; it is sufficient to ensure that there is enough solution for atomization.

[0142] Optionally, the height of the second preset liquid level is 0.1-0.8 times the height of the glasses.

[0143] S3: Start the ultrasonic generator and maintain atomization duration.

[0144] The ultrasonic vibration energy generated by the ultrasonic generator atomizes the solution, and the atomized particles diffuse fully within the cleaning chamber, quickly achieving thorough cleaning of the sides of the lenses, the frame, and the nose pads, thus avoiding any blind spots in the cleaning process.

[0145] S4; Allow the glasses to stand for a preset interval to allow the atomized particles to fully wet the glasses.

[0146] By letting it stand for a period of time, the atomized particles can be fully in contact with the glasses, allowing the surface of the glasses to be thoroughly moistened by the atomized particles before cleaning.

[0147] S5: Inject water into the cleaning chamber to bring the solution level in the cleaning chamber to the first preset level.

[0148] The first preset liquid level is higher than the height of the glasses, so that the glasses are completely immersed in the solution to ensure the ultrasonic cleaning effect.

[0149] It should be noted here that no drainage is performed after step S4, and the cleaning agent added before atomization continues to act on the glasses.

[0150] S6: Start the ultrasonic generator and continue for the first preset duration to perform ultrasonic cleaning.

[0151] After the ultrasonic generator is turned on, it transmits vibrational energy through the solution to the dirt, grease, sebum, and other grime covering the surface of the glasses. Through cavitation, the tiny bubble nuclei in the solution rapidly expand and burst. The bursting of the tiny bubble nuclei generates shock waves, which peel off the dirt and achieve a cleaning effect.

[0152] The ultrasonic generator operates continuously for the first preset time to ensure effective cleaning of the glasses.

[0153] S7: Continue to inject water into the cleaning chamber for overflow drainage and continue for the second preset time.

[0154] Overflow drainage is achieved by injecting water into the cleaning chamber, ensuring that the liquid level in the cleaning chamber is always within the height range of the overflow port. This guarantees that dirt on the surface of the solution can be discharged through the overflow port, preventing dirt from re-adhering to the surface of the glasses.

[0155] S8: Drain the water from the cleaning chamber.

[0156] After the second preset overflow drainage time, all the dirt on the solution surface will be discharged. At this time, normal drainage will be started to drain the water out of the cleaning chamber.

[0157] Alternatively, the water in the cleaning chamber can be drained by means of siphon drainage, pump drainage, or valve drainage.

[0158] S9: Repeat steps S5-S8 a preset number of times.

[0159] Repeat steps S5-S8, without adding any more cleaning agent to the cleaning chamber, to achieve multiple rinsing.

[0160] S10: Inject cleaning agent and water into the cleaning chamber to bring the solution level in the cleaning chamber to the first preset level.

[0161] After the cleaning stage, the dirt on the glasses has been removed, and it is only necessary to ensure that there are no water droplets on the lens surface. To do this, water and cleaning agent are injected into the cleaning chamber, ensuring the liquid level reaches the first preset level to guarantee that the glasses are completely submerged in the solution. Adding cleaning agent reduces the surface tension of the water, preventing water droplets from remaining on the lenses.

[0162] S11: The cleaning chamber is drained slowly so that the liquid level in the cleaning chamber drops at a rate not exceeding 15 mm / s, in order to avoid water droplets remaining on the surface of the object to be cleaned.

[0163] When water is drained slowly, the surface tension of the water itself is reduced, making it less likely to form water droplets. As the water level slowly drops, even if water droplets may form in some areas, the surface tension of the slowly descending water can restrain these droplets, thus pulling them down with the water level and preventing water droplets from remaining on the surface of the glasses.
