Description

Technical Field

[0001] The invention belongs to the technical field of kitchen and bathroom sanitary ware, and in particular relates to an ultrasonic cleaning sink and a control method thereof. Background Art

[0002] As an indispensable cleaning appliance in the home, sinks are used for washing dishes, vegetables, and fruits, bringing great convenience to users. Currently, sink cleaning methods include spray cleaning and ultrasonic cleaning. Ultrasonic cleaning is particularly popular among consumers due to its advantages such as fast cleaning speed, good cleaning effect, no damage to the workpiece surface, and high cleaning precision.

[0003] Currently, household ultrasonic cleaning sinks utilize an ultrasonic generator to drive an ultrasonic oscillator to generate a large number of tiny bubbles. These bubbles adhere to the surface of fruits and vegetables or tableware, and the bursting of the bubbles removes agricultural residues or oil stains from the surface of the tableware. However, the bubbles are not capable of carrying away mud, sand, and large particles of dirt, and the cleaning effect still needs to be further improved. Moreover, the washing process of ultrasonic cleaning sinks is simple.

[0004] It can be seen that the existing ultrasonic cleaning tanks are difficult to meet the needs of consumers. Summary of the Invention

[0005] One of the purposes of the present invention is to provide an ultrasonic cleaning water tank that can enhance the cleaning and flushing ability of large particles of dirt, further improve the washing effect, and meet the usage needs of consumers.

[0006] In addition, a second object of the present invention is to provide a control method for an ultrasonic cleaning tank.

[0007] The technical solutions adopted to solve the above technical problems are:

[0008] In a first aspect, the present invention discloses an ultrasonic cleaning tank, comprising:

[0009] The tank body has a cleaning cavity with an upward opening, and a side wall of the cleaning cavity is provided with a mounting opening;

[0010] an ultrasonic vibrator assembly, located below the cleaning chamber and connected to the tank body;

[0011] A circulation pump device is arranged at the installation port, and the circulation pump device includes an end cover, a guide vane, an impeller assembly and a housing. The guide vane is located between the end cover and the housing, and the guide vane is connected to the end cover to form a water inlet chamber. The end cover is provided with a water inlet hole and a water outlet hole, and the water inlet hole is connected to the water inlet chamber. The guide vane is connected to the housing to form a vortex chamber. The guide vane is provided with a first through hole and a second through hole. The first through hole is located in the middle of the guide vane and is respectively connected to the water inlet chamber and the vortex chamber. The second through hole is located on the periphery of the first through hole, and the vortex chamber, the second through hole and the water outlet are connected in sequence. The impeller assembly is arranged in the vortex chamber.

[0012] The ultrasonic cleaning water tank provided by the present invention has at least the following beneficial effects: the tank body is not only provided with an ultrasonic vibrator assembly to realize the ultrasonic cleaning function, but also provided with a circulating pump device. During the operation of the circulating pump device, the impeller assembly rotates at high speed, so that a vortex is formed in the vortex chamber, presenting a negative pressure in the middle of the vortex and a positive pressure on the periphery. Then, the water in the cleaning chamber will flow through the water inlet hole, the water inlet chamber and the first through hole of the end cover due to the negative pressure, and then enter the vortex chamber. The water in the vortex chamber is ejected from the second through hole and the water outlet hole at high pressure under the action of the impeller assembly. Therefore, a rapid circulation flow of water is formed between the cleaning chamber and the circulating pump device. The circulating pump device is used to generate circulating surges in the cleaning chamber, which can perform high-pressure flushing on fruits, vegetables or tableware, remove large particles of dirt on the fruits, vegetables or tableware, promote the improvement of the cleaning effect of the ultrasonic cleaning water tank, and meet the user's usage needs.

[0013] As a further improvement to the above technical solution, the circulating pump device further includes an air inlet pipe; the end of the air inlet pipe near the end cap penetrates the housing and extends into the water outlet. This arrangement creates a negative pressure at the end of the air inlet pipe near the water outlet when high-pressure water is ejected from the water outlet, allowing external air to flow into the air inlet pipe, thereby generating a large number of bubbles in the water flow, enhancing the scouring effect of the surge on the objects to be cleaned, and further improving the cleaning quality and work efficiency of the ultrasonic cleaning tank.

[0014] As a further improvement to the above technical solution, the end cover, the guide vane and the shell are detachably connected, the aperture of the water inlet hole is smaller than the aperture of the water outlet hole, and the water inlet area of ​​the end cover is equal to the water outlet area. The water inlet hole is arranged in this way to prevent dirt such as mud, sand, and broken leaves from entering the vortex chamber through the water inlet hole, thereby preventing the impeller assembly from being blocked and running smoothly; in the end cover, the water inlet area and the water outlet area are equal, that is, the sum of the areas of all water inlet holes is equal to the sum of the areas of all water outlet holes, which promotes the balance of water inlet and water outlet, thereby ensuring smooth water inlet and outlet; the end cover, the guide vane and the shell are detachably connected, which facilitates the removal of the end cover and the guide vane to remove dirt in the water inlet chamber and the vortex chamber.

[0015] As a further improvement to the above technical solution, the housing is detachably connected to the tank, and the end cap is connected to the housing via a rotating buckle structure. The detachable connection between the housing and the tank facilitates assembly and disassembly of the circulating pump device from the tank, reducing maintenance difficulties for the circulating pump device. The rotating buckle connection between the end cap and the housing allows the user to manually rotate the end cap for removal without the need for tools.

[0016] As a further improvement to the above technical solution, the impeller assembly includes a rotating impeller and a magnetic levitation motor, with the rotating impeller connected to the rotor of the magnetic levitation motor. This arrangement enables the magnetic levitation motor to drive the rotating impeller to rotate smoothly and at high speed, avoiding vibration and noise. Furthermore, the circulating pump device is friction-free, maintenance-free, energy-efficient, and lubricant-free, making it ideal for use in ultrasonic tank cleaning.

[0017] As a further improvement of the above technical solution, the side wall of the cleaning chamber is provided with a water inlet; the ultrasonic cleaning water tank further comprises:

[0018] a water inlet assembly, which is located outside the cleaning chamber and connected to the tank body, the water inlet assembly having a mixing chamber and a feed chamber, the feed chamber being located above the mixing chamber and communicating with the mixing chamber, the upper portion of the feed chamber being provided with a first opening, the side wall of the feed chamber being provided with a feed port located below the first opening, the mixing chamber being provided with a second opening, the second opening being communicated with the water inlet, the water inlet assembly being provided with a water inlet, the water inlet being communicated with the mixing chamber, and being located on a side of the feed chamber away from the second opening;

[0019] The washing powder adding device comprises a discharge port, wherein the discharge port is communicated with the feed port.

[0020] A water inlet assembly is provided to allow tap water to flow sequentially through the water inlet, the mixing chamber, the second opening and the water inlet into the cleaning chamber; the discharge port of the detergent powder adding device is connected to the feed port of the water inlet assembly, allowing the detergent powder to enter the feed chamber through the discharge port and the feed port in sequence, and then automatically fall into the mixing chamber due to gravity, and mix with the water in the mixing chamber and flow into the cleaning chamber together; detergent powder is added while water is being fed in, and the kinetic energy of the water is used to drive the detergent powder to move, so that the detergent powder is more evenly distributed in the cleaning chamber.

[0021] As a further improvement of the above technical solution, the water inlet is located on the lower wall of the mixing chamber, and the water inlet assembly is provided with a guide plate, which is located on the side of the feed chamber away from the second opening and is connected to the side wall of the mixing chamber. There is a gap between the lower surface of the guide plate and the lower wall of the mixing chamber, and the lower surface of the guide plate is arranged opposite to the water inlet.

[0022] With this arrangement, the guide plate will block and suppress the water column ejected from the water inlet, causing the water to flow along the lower surface of the guide plate. After the water flows through the guide plate, it will form an inward-spraying water curtain due to the increase in the cross-sectional area of ​​the water flow, which can be fully stirred and mixed with the detergent powder dropped into the mixing chamber, thereby causing the detergent powder to be more evenly distributed in the cleaning chamber, thereby helping to improve the cleaning effect.

[0023] As a further improvement of the above technical solution, the side wall of the cleaning chamber is provided with an overflow port, the water inlet assembly has an overflow chamber, the overflow chamber is provided with a third opening and a drain port, and the third opening is connected to the overflow port; the water inlet assembly is provided with a groove with an upward opening, the groove is higher than the circulating pump device, and the wall surface of the groove is provided with a connecting hole, one end of the air inlet pipe is connected to the connecting hole, and the other end passes through the shell and extends to the water outlet.

[0024] With this arrangement, when overflow occurs in the cleaning chamber, excess water will enter the overflow chamber and be discharged, thus preventing excessive accumulation of water in the cleaning chamber; the air inlet pipe of the circulating pump device is connected to the connecting hole of the water inlet component to form a certain height difference, while ensuring that external air can flow into the air inlet pipe, which can prevent the water in the cleaning chamber from flowing out from the air inlet pipe when the circulating pump device is not running.

[0025] As a further improvement of the above technical solution, the detergent powder adding device includes a detergent powder box, a motor, a feeding screw and a feeding hopper; the detergent powder box has a storage chamber, the feeding hopper is provided with a conveying chamber, the detergent powder box is located above the feeding hopper, the storage chamber is connected to the conveying chamber, the discharge port is provided on the side wall of the conveying chamber, one end of the feeding screw is connected to the output shaft of the motor, and the other end extends to the discharge port, and the detergent powder box is provided with an adding port connected to the storage chamber.

[0026] The motor is used to drive the feeding screw to rotate, so that the feeding screw transports the detergent powder in the conveying chamber to the discharge port. The number of revolutions driven by the motor to rotate the feeding screw can be controlled to help control the amount of detergent added. The storage chamber of the detergent powder box can store a large amount of detergent powder for multiple detergent powder additions. There is no need to frequently replenish detergent powder in the detergent powder adding device. The detergent powder in the storage chamber will flow down to the conveying chamber due to gravity.

[0027] In a second aspect, the present invention further discloses a control method for an ultrasonic cleaning water tank, which is applied to the ultrasonic cleaning water tank of the above technical solution, comprising the following steps:

[0028] Water injection process: operating the water inlet component and performing water metering. If the first set value is reached, the water inlet component is stopped. If the soaking process is completed, the cleaning process is started.

[0029] Detergent adding process: operating the detergent adding device and measuring the detergent powder, and if the second set value is reached, stopping the detergent adding device;

[0030] Soaking process: After the water injection and detergent powder addition are completed, the soaking time is counted. If the first set time is reached, the soaking process is stopped and the washing process is started;

[0031] Cleaning process: operating the ultrasonic vibrator assembly and the circulating pump device, and timing, if reaching the second set time, stopping the ultrasonic vibrator assembly and the circulating pump device, and entering the drainage process;

[0032] Draining process: drain the cleaning chamber. After draining, enter the water filling process. If the number of execution times of the cleaning process reaches the third set value, the process ends.

[0033] The control method of the ultrasonic cleaning water tank provided by the present invention has at least the following beneficial effects: the control method can scientifically wash different washing items, and can set the water amount in the water filling process and the detergent powder amount in the detergent powder adding process, the duration of the soaking process and the duration of the cleaning process according to the conditions of the washing items, so as to facilitate the one-click execution of the cleaning operation; when the ultrasonic cleaning water tank is working, after completing the water filling and detergent powder adding, it will enter the soaking process; after completing the soaking process, it will enter the cleaning process, using the ultrasonic vibrator component and the circulation pump device to enhance the cleaning effect of the washing items; after completion, the water is drained and water is filled, thereby entering the rinsing process; during the rinsing process, there is no need to add detergent powder, only the ultrasonic vibrator component and the circulation pump device need to be operated to flush away the dirt and residual detergent powder on the surface of the washing items; such a setting makes the ultrasonic cleaning water tank have the advantages of high intelligence, diverse cleaning procedures, and good cleaning quality and efficiency.

[0056] Reference Figures 1 to 14, several embodiments of the ultrasonic cleaning water tank and the control method thereof of the present invention are given below.

[0057] like Figures 1 to 3 、 Figure 8 and Figure 9 As shown, the first embodiment of the present invention provides an ultrasonic cleaning sink that can be used for washing fruits, vegetables, tableware, etc. The structure of the ultrasonic cleaning sink includes a sink body 100, an ultrasonic vibrator assembly 400, and a circulating pump device 200. The ultrasonic cleaning sink not only has an ultrasonic cleaning function, but also has a strong ability to clean and flush large particles of dirt, resulting in excellent cleaning effects.

[0058] The tank body 100 has a cleaning chamber 122 with an upward opening, into which the user can place items to be washed, such as vegetables or tableware. The tank body 100 is provided with an installation opening, which is located on the side wall of the cleaning chamber 122. In this embodiment, the installation opening is located on the rear side wall of the cleaning chamber 122.

[0059] The lower wall of the cleaning chamber 122 is provided with a drain port 131, which is connected to a drain pipe 132 for draining water from the cleaning chamber 122. The drain pipe 132 is provided with a drain valve 133, which is an electrically controlled valve. The upper surface of the tank body 100 is provided with a display control panel 150, and the bottom of the tank body 100 is installed with an electrically controlled drive box 700. The display control panel 150 and the electrically controlled drive box 700 are both existing products. The drain valve 133 and the display control panel 150 are electrically connected to the electrically controlled drive box 700, respectively. The user can control the drain valve 133 to open or close by inputting operating instructions into the display control panel 150. The display control panel 150 can be a touch screen.

[0060] The tank body 100 is made of metal. The tank body 100 is not only provided with a cleaning chamber 122, but also provided with a washing chamber 121. The washing chamber 121 can be located on the left side of the washing chamber 122. The washing chamber 121 is a conventional cleaning area and does not have an ultrasonic cleaning function. The tank body 100 is equipped with a faucet 110 to fill the washing chamber 121 with water. In this embodiment, two faucets 110 are provided, one of which has a water purification function. Of course, the faucet 110 can adopt a rotating design. By rotating the faucet 110, the faucet 110 can be used to fill the washing chamber 121 or the cleaning chamber 122 with water.

[0061] The ultrasonic vibrator assembly 400 is located below the cleaning chamber 122 and is fixedly connected to the tank body 100. It is understood that the ultrasonic vibrator assembly 400 is conventional and consists of an ultrasonic transducer and an ultrasonic horn. When activated, the ultrasonic vibrator assembly 400 can ultrasonically clean the items in the cleaning chamber 122.

[0062] The circulation pump device 200 is disposed at the installation opening of the tank body 100 so that the circulation pump device 200 can be fixed relative to the tank body 100 .

[0063] like Figure 8 and Figure 9 As shown, the structure of the circulating pump device 200 includes an end cover 210 , a guide vane 220 , an impeller assembly and a housing 230 .

[0064] The guide vane 220 is disposed between the end cover 210 and the housing 230. The guide vane 220 and the end cover 210 are interconnected to form a water inlet chamber 252. The end cover 210 is provided with a water inlet hole 212 and a water outlet hole 211. The water inlet hole 212 is connected to the water inlet chamber 252. The guide vane 220 and the housing 230 are interconnected to form a vortex chamber 251. The guide vane 220 is provided with a first through hole 221 and a second through hole 222. The first through hole 221 is located in the middle of the guide vane 220. Moreover, one end of the first through hole 221 is connected to the water inlet chamber 252, and the other end of the first through hole 221 is connected to the vortex chamber 251. The second through hole 222 is located on the periphery of the first through hole 221. Moreover, the vortex chamber 251, the second through hole 222, and the water outlet hole 211 are sequentially connected.

[0065] The impeller assembly is disposed within the vortex chamber 251. The impeller assembly is capable of rotating relative to the housing 230. Specifically, the impeller assembly comprises a rotating impeller 232 and a magnetic levitation motor. The rotating impeller 232 is fixedly connected to the rotor of the magnetic levitation motor. The rotor of the magnetic levitation motor extends through the housing 230 and into the vortex chamber 251, connecting the rotor to the rotating impeller 232. A rubber ring can be used to seal the gap between the rotor and the housing 230 to prevent water within the vortex chamber 251 from leaking through the gap between the rotor and the housing 230.

[0066] It is understood that the structure of a magnetic levitation motor is conventional. A magnetic levitation motor primarily comprises a rotor and a stator, with the rotor capable of high-speed rotation relative to the stator. Those skilled in the art should understand the specific structure and operating principles of a magnetic levitation motor. In this embodiment, the magnetic levitation motor includes an electromagnetic module 240 and a magnetic shaft 231. The magnetic shaft 231 serves as the rotor. The electromagnetic module 240 comprises two electromagnetic induction steel sheets 241, which wrap around the magnetic shaft 231. Furthermore, the electromagnetic module 240 also includes magnetic bearings, which are mounted on the magnetic shaft 231. The magnetic bearings maintain a stable suspended state. The electromagnetic induction steel sheets 241 are wound with electromagnetic coils. When the electromagnetic coils are energized, the electromagnetic induction steel sheets 241 generate an electromagnetic field, which, through electromagnetic induction, drives the magnetic shaft 231 to rotate at high speed, thereby rotating the impeller 232. The electromagnetic membrane assembly has two terminals for connection to the mains power supply.

[0067] Of course, the rotating impeller 232 can also be connected to the output shaft of a conventional motor, so that the output shaft of the motor drives the rotating impeller 232 to rotate.

[0068] It can be understood that the mechanism for driving the rotating impeller 232 to rotate adopts a magnetic levitation motor, which can enable the magnetic levitation motor to drive the rotating impeller 232 to rotate at high speed and smoothly, avoiding vibration and noise. Moreover, it enables the circulating pump device 200 to have the advantages of no friction and wear, no maintenance, energy saving and consumption reduction, and no lubricating oil pollution, and is very suitable for use in ultrasonic cleaning water tanks.

[0069] During the operation of the circulation pump device 200, the impeller assembly rotates at high speed, causing a vortex to form in the vortex chamber 251, presenting a negative pressure in the middle of the vortex and a positive pressure on the periphery; then, the water in the cleaning chamber 122 will flow through the water inlet hole 212, the water inlet chamber 252 and the first through hole 221 of the end cover 210 due to the negative pressure, and then enter the vortex chamber 251. Under the action of the impeller assembly, the water in the vortex chamber 251 is ejected from the second through hole 222 and the water outlet hole 211 at high pressure. The water inlet 212 and the water outlet 211 are both located on the same surface of the end cover 210. The water inlet 212 continuously absorbs water and replenishes the flow by using negative pressure, and the water outlet 211 continuously ejects water. Therefore, a rapid circulation of water is formed between the cleaning chamber 122 and the circulating pump device 200. The circulating pump device 200 is used to generate circulating surges in the cleaning chamber 122, which can perform high-pressure flushing on fruits, vegetables or tableware, remove large particles of dirt on fruits, vegetables or tableware, promote the improvement of the cleaning effect of the ultrasonic cleaning sink, and meet the user's usage needs.

[0070] Moreover, the circulating pump device 200 adopts the above configuration, making the ultrasonic cleaning water tank structure more compact, easier to assemble and maintain, and no additional water suction port of the circulating pump device 200 is required in the cleaning chamber 122. Of course, the number of circulating pump devices 200 is not limited to one.

[0071] In this embodiment, since the circulation pump device 200 is mounted on the rear sidewall of the cleaning chamber 122, the axes of the water inlet hole 212, the water outlet hole 211, the first through hole 221, and the second through hole 222 all extend in the front-to-back direction. The water inlet chamber 252 is located in front of the vortex chamber 251. The rotation axis of the rotary impeller 232 extends in the front-to-back direction.

[0072] Both the water inlet hole 212 and the water outlet hole 211 are circular holes, with the diameter of the water inlet hole 212 being smaller than that of the water outlet hole 211. In this embodiment, there are two water outlet holes 211, arranged circumferentially about the centerline of the end cap 210. Of course, the number of water outlet holes 211 is not limited to one or two. There can be multiple water inlet holes 212, distributed on the front side of the end cap 210.

[0073] It is understood that the water outlet hole 211 is sized large to ensure that the water in the vortex chamber 251 can be ejected smoothly from the water outlet hole 211. The water inlet hole 212 is sized small to prevent dirt such as mud, sand, and broken leaves from entering the vortex chamber 251 through the water inlet hole 212, which could cause the impeller assembly to become clogged and operate unsmoothly. At the same time, the number of fine water inlet holes 212 is sufficient to make the water inlet area and water outlet area of ​​the end cover 210 equal. In other words, the sum of the areas of all the water inlet holes 212 is equal to the sum of the areas of all the water outlet holes 211, so that the water inflow and water outflow in the vortex chamber 251 are balanced, thereby ensuring smooth water inflow and outflow.

[0074] The end cover 210 and the guide plate 220 , and the guide plate 220 and the housing 230 are connected in a detachable manner, such as a threaded connection, a screw connection, or a rotary snap connection, which is not limited here.

[0075] In this embodiment, the guide vane 220 abuts the end cap 210 and also abuts the housing 230. The end cap 210 and the housing 230 are connected by a rotating snap-fit ​​structure. Specifically, the outer wall of the housing 230 is provided with a slot, and the end cap 210 is provided with a protrusion. By rotating the end cap 210, the protrusion can be screwed into the slot, thereby causing the end cap 210 to be fixedly connected to the housing 230. With this arrangement, the user can manually rotate the end cap 210 to separate the end cap 210 from the housing 230, thereby removing the end cap 210 and the guide vane 220 and clearing dirt from the water inlet chamber 252 and the vortex chamber 251, thereby preventing the circulation pump device 200 and its waterway from clogging. During maintenance, no auxiliary tools such as screwdrivers are required. This arrangement enables rapid disassembly and installation of the end cap 210 and the guide vane 220, and facilitates efficient cleaning of the water inlet chamber 252 and the vortex chamber 251.

[0076] Of course, the end cover 210 can also be detachably connected to the housing 230 via a threaded structure.

[0077] The housing 230 is detachably connected to the tank body 100. Specifically, the outer wall of the housing 230 is provided with an external thread, which is threadedly connected to the tank body 100. Of course, a rubber ring can be used to seal the housing 230 and the tank body 100 to prevent water leakage.

[0078] In some embodiments, as Figure 8 and Figure 9 As shown, the structure of the circulation pump device 200 also includes an air inlet pipe 233.

[0079] The end of the air inlet pipe 233 near the end cover 210 passes through the housing 230 and extends into the water outlet 211. In this embodiment, the number of air inlet pipes 233 is the same as the number of water outlets 211, and they are arranged in a one-to-one correspondence. The air inlet pipe 233 extends in the front-to-back direction. After the front end of the air inlet pipe 233 passes through the housing 230, it passes through the second through-hole 222 and extends to the water outlet 211. The air inlet pipe 233 and the housing 230 are integrally formed. The rear end of the air inlet pipe 233 is open, so that external air can flow into the air inlet pipe 233. A connecting pipe 540 is provided at the rear end of the air inlet pipe 233. The connecting pipe 540 is higher than the circulation pump device 200. Therefore, when the circulation pump device 200 is not in operation, the water in the cleaning chamber 122 will not flow out through the air inlet pipe 233.

[0080] When water is ejected at high pressure from the water outlet 211, negative pressure is generated at the end of the air inlet pipe 233 close to the water outlet 211, allowing external air to flow into the air inlet pipe 233 and out from the front end opening of the air inlet pipe 233, thereby causing a large number of bubbles to be generated in the water flow, enhancing the high-pressure flushing effect of the surge on the object to be cleaned, and further improving the cleaning quality and work efficiency of the ultrasonic cleaning tank.

[0081] In some embodiments, as Figures 1 to 7 As shown, the ultrasonic cleaning water tank has the functions of automatic water inlet and automatic detergent powder addition. The structure of the ultrasonic cleaning water tank also includes a water inlet component 500 and a detergent powder adding device 300.

[0082] The tank body 100 is provided with a water inlet 141, which is located on the side wall of the cleaning chamber 122. The number of water inlets 141 is not limited to one, and the shape of the water inlet 141 can be circular or elongated, without limitation. In this embodiment, the water inlet 141 is located on the rear side wall of the cleaning chamber 122.

[0083] The water inlet assembly 500 is disposed outside the cleaning chamber 122 and is fixedly connected to the tank body 100. The water inlet assembly 500 includes a housing 510, a water inlet pipe 530, and a water inlet valve 600.

[0084] The housing 510 can be made of plastic. The housing 510 is hollow and has a mixing chamber 511 and a feeding chamber 521 formed therein. The feeding chamber 521 is located above the mixing chamber 511 and is connected to the mixing chamber 511. Both the feeding chamber 521 and the mixing chamber 511 are square cavities.

[0085] The housing 510 is provided with a first opening, a second opening, a water inlet 515 and a feed inlet 522 .

[0086] The first opening is located at the top of the feed cavity 521, and the feed port 522 is provided on the sidewall of the feed cavity 521, below the first opening. In this embodiment, the upper surface of the housing 510 is raised to form a prismatic raised portion 520. The feed cavity 521 extends through the upper and lower surfaces of the raised portion 520, and the feed port 522 is located on the left sidewall of the feed cavity 521. The feed port 522 may be circular.

[0087] The detergent powder adding device 300 has a discharge port 322 , which is connected to the feed port 522 .

[0088] Specifically, the structure of the detergent powder adding device 300 includes a detergent powder box 310 , a feeding hopper 320 , a motor 330 and a feeding screw 340 .

[0089] Among them, the washing powder box 310 is hollow and has a storage chamber 313 formed inside. The storage chamber 313 can store a certain amount of washing powder, such as baking soda. The washing powder box 310 is provided with an addition port, which is connected to the storage chamber 313. Then, the user can add washing powder to the storage chamber 313 through the addition port. In the present embodiment, the washing powder box 310 includes a box body 312 and a lid 311. The box body 312 has an inner cavity, which runs through the upper and lower surfaces of the box body 312. The upper end opening of the inner cavity is the addition port. The lid 311 is covered on the box body 312. The lid 311 can cover the addition port and together with the box body 312, define the storage chamber 313. It is understandable that by opening the lid 311, washing powder can be added to the storage chamber 313. After covering the lid 311, the washing powder in the storage chamber 313 can be prevented from getting damp.

[0090] The detergent powder box 310 is disposed above the hopper 320 and can be integrally formed with the hopper 320. The hopper 320 is hollowed out to form a conveying cavity 321, which is connected to the storage cavity 313. Then, the detergent powder in the storage cavity 313 can flow into the conveying cavity 321 due to gravity.

[0091] The hopper 320 is provided with a discharge port 322, located on the sidewall of the conveying chamber 321. One end of a feed screw 340 is connected to the output shaft of the motor 330. Specifically, the output shaft of the motor 330 and the feed screw 340 are connected via a coupling. The motor 330 is fixed to the hopper 320 via a screw connection and is located outside the conveying chamber 321. The other end of the feed screw 340 extends to the discharge port 322. The feed screw 340 and the discharge port 322 are arranged coaxially.

[0092] In this embodiment, the discharge port 322 is located on the right side wall of the hopper 320. Both ends of the feed screw 340 extend in the left-right direction. The hopper 320 is fixedly connected to the protrusion 520 on the housing 510. The connection method may be adhesive, threaded, etc. The hopper 320 is mounted on the tank body 100. The motor 330 may be a servo motor or a stepper motor.

[0093] Motor 330 is started, and its output shaft drives feed screw 340 to rotate, causing feed screw 340 to deliver detergent powder within delivery chamber 321 from discharge port 322 to feed chamber 521 of water inlet assembly 500, thereby automatically adding detergent powder. By controlling the number of revolutions of feed screw 340 driven by motor 330, the amount of detergent added can be precisely controlled. Compared to manual addition of detergent powder, this arrangement provides significant convenience for the user. Furthermore, the amount of detergent added can be precisely controlled, avoiding the problems of excessive and wasted detergent, or insufficient detergent, resulting in poor washing results.

[0094] It is understandable that the storage chamber 313 of the detergent powder box 310 can store a large amount of detergent powder for multiple additions of detergent powder. There is no need to frequently replenish detergent powder into the detergent powder adding device 300. The detergent powder in the storage chamber 313 will flow downward to the conveying chamber 321 due to gravity.

[0095] In this embodiment, the left end of hopper 320 extends leftward to form an extension located above motor 330. This increases the size of the upper portion of hopper 320, thereby increasing the size of detergent box 310 and allowing for more storage space in storage chamber 313 and delivery chamber 321. To ensure the smooth and automatic drop of detergent powder from the extension, the inner lower wall of the extension is formed into a slope 323 that slopes downward from left to right, allowing the detergent powder to slide down to feed screw 340 due to gravity.

[0096] The mixing chamber 511 penetrates the surface of the housing 510 near the tank body 100 to form a second opening. After the housing 510 is connected to the tank body 100, the second opening is connected to the water inlet 141. The water inlet 515 is connected to the mixing chamber 511, and the water inlet 515 is located on the side of the feeding chamber 521 away from the second opening. Then, the detergent powder falling from the feeding chamber 521 into the mixing chamber 511 can be mixed with the water flowing in the mixing chamber 511. In this embodiment, the second opening is located on the front side of the housing 510, and the water inlet 515 is set at the rear of the housing 510. The water inlet 515 can be set on the lower wall of the mixing chamber 511. Of course, the water inlet 515 can also be set on the rear side wall of the mixing chamber 511.

[0097] The water inlet pipe 530 is connected to the water inlet 515 via a threaded structure. An electrically controlled water inlet valve 600 is installed on the water inlet pipe 530. When the water inlet valve 600 is opened, tap water flows through the water inlet pipe 530, the water inlet 515, the mixing chamber 511, the second opening, and the water inlet 141, entering the cleaning chamber 122, providing sufficient water for cleaning.

[0098] The discharge port 322 of the detergent adding device 300 is connected to the feed port 522 of the water inlet assembly 500. The detergent powder enters the feed chamber 521 through the discharge port 322 and the feed port 522 in sequence. The detergent powder then automatically falls into the mixing chamber 511 due to gravity and mixes with the water in the mixing chamber 511, allowing the detergent powder and water to flow together into the cleaning chamber 122. The detergent powder is added while the water is being fed in, and the kinetic energy of the water is used to drive the detergent powder, ensuring a more even distribution of the detergent powder within the cleaning chamber 122.

[0099] In some embodiments, the water inlet 515 is disposed on the lower wall of the mixing chamber 511, and the water inlet assembly 500 is provided with a guide plate 560, which is horizontally disposed and located above the water inlet 515. The guide plate 560 is located on the side of the feed chamber 521 away from the second opening. The guide plate 560 is fixedly connected to the side wall of the mixing chamber 511. A gap is defined between the lower surface of the guide plate 560 and the lower wall of the mixing chamber 511. The size of the gap can be adjusted according to actual conditions. The lower surface of the guide plate 560 is disposed opposite the water inlet 515.

[0100] In this embodiment, the guide plate 560 is located at the rear side of the feed chamber 521. The left side, right side and rear side of the guide plate 560 are respectively connected and fixed to the corresponding wall surfaces of the mixing chamber 511. When viewed from the right, the front side of the guide plate 560 extends forward to the connection between the mixing chamber 511 and the feed chamber 521. Figure 6 As shown in FIG. 1 , the aperture of the water inlet 515 is smaller than the projected area of ​​the guide plate 560 when viewed from above. Figure 5 and Figure 6 shown.

[0101] When the water inlet assembly 500 is activated, tap water is sprayed upward from the water inlet 515. At this time, the guide plate 560 will block and suppress the water column sprayed from the water inlet 515, causing the water to flow along the lower surface of the guide plate 560. After the water flows through the guide plate 560, the water will form an inward-spraying water curtain due to the increase in the cross-sectional area of ​​the water flow. Specifically, when the water in the mixing chamber 511 just leaves the guide plate 560, the water that impacts the left and right side walls of the mixing chamber 511 will roll upward due to the loss of the blocking effect of the guide plate 560, thereby forming an inward-spraying water curtain. Therefore, the water in the mixing chamber 511 can be fully stirred and mixed with the detergent powder that falls into the mixing chamber 511, so that the detergent powder is more evenly distributed in the cleaning chamber 122, which helps to improve the cleaning effect and avoid the detergent powder in the mixing chamber 511 staying on the upper part of the water in the mixing chamber 511 and being unevenly distributed.

[0102] In some embodiments, as Figures 1 to 6 As shown, the ultrasonic cleaning water tank has an anti-overflow function. Specifically, the side wall of the cleaning chamber 122 is provided with an overflow port 142, and the overflow port 142 and the water inlet 141 are located on the same side wall of the cleaning chamber 122. An overflow chamber 512 is formed hollow inside the shell 510, and the overflow chamber 512 penetrates the surface of the shell 510 close to the tank body 100 to form a third opening. After the shell 510 is connected to the tank body 100, the third opening is connected to the overflow port 142. The shell 510 is provided with a drain port 516, which is connected to the overflow chamber 512. The drain port 516 can be connected to a drain pipe. When the cleaning chamber 122 overflows, the excess water will enter the overflow chamber 512 and be discharged through the drain pipe to avoid excessive accumulation of water in the cleaning chamber 122.

[0103] In this embodiment, the overflow port 142 is located on the rear sidewall of the cleaning chamber 122. There are two overflow chambers 512, one on each side of the mixing chamber 511. A single drain port 516 is provided on the left side of the housing 510. Both overflow chambers 512 are provided with a communication port, which is connected by a conduit 517, allowing water in both overflow chambers 512 to be discharged through the single drain port 516.

[0104] A sealing ring 550 is provided on the front side of the shell 510. The sealing ring 550 is a rubber ring or a silicone ring. The sealing ring 550 surrounds the third opening of the overflow chamber 512 and the second opening of the mixing chamber 511. After the shell 510 is connected and fixed to the tank body 100, the sealing ring 550 will be deformed under pressure, thereby achieving a good sealing effect and preventing water in the overflow chamber 512 and the mixing chamber 511 from leaking from the gap between the shell 510 and the tank body 100.

[0105] In some embodiments, as Figures 3 to 5 、 Figure 8 and Figure 9As shown, the water inlet assembly 500 is provided with a groove 513, the opening of which is arranged upward. Specifically, the upper surface of the housing 510 is recessed downward to form the groove 513. The height of the groove 513 is higher than the height of the circulating pump device 200. The wall of the groove 513 is provided with a connecting hole 514. One end of the air inlet pipe 233 is connected to the connecting hole 514. The other end of the air inlet pipe 233 passes through the housing 230 and extends to the water outlet 211. In this embodiment, the connecting hole 514 is located on the lower wall of the groove 513.

[0106] The air inlet pipe 233 of the circulation pump device 200 is connected to the connecting hole 514 of the water inlet assembly 500 so that a certain height difference is formed between the air inlet pipe 233 and the groove 513. Then, while ensuring that external air can flow into the air inlet pipe 233, it is possible to prevent water in the cleaning chamber 122 from flowing out of the air inlet pipe 233 when the circulation pump device 200 is not running.

[0107] It is understandable that the above-mentioned motor, electric control valve, ultrasonic vibrator assembly 400 and circulation pump device 200 are all electrically connected to the electric control drive box 700 , and the user can control them through the display control panel 150 .

[0108] In addition, if Figures 1 to 14 As shown, an embodiment of the present invention provides a control method for an ultrasonic cleaning water tank, which is applied to the ultrasonic cleaning water tank of the above embodiment.

[0109] It is understood that the program corresponding to this control method can be stored in the electronically controlled drive box 700. Users or manufacturers can preset washing parameters such as the washing water level, amount of detergent, soaking time, ultrasonic cleaning and surge flushing time, rinsing time, and number of rinses based on the type of ingredients to be washed and the amount of laundry to be washed. This allows users to easily select the appropriate washing program and execute the cleaning operation with one click, eliminating the need for complex parameter input. The embodiments of the present invention can scientifically configure corresponding soaking, washing, rinsing, and other programs for different laundry items.

[0110] Specifically, the control method includes the following steps:

[0111] The process begins at step S1. After the user turns on the machine and selects the corresponding washing program, it enters step S2: the water filling process. Step S2 includes steps S21, S22, S23, and S24.

[0112] Among them, step S21: operate the water inlet component 500. Specifically, the water inlet valve 600 is opened under the control command, allowing tap water to flow into the cleaning chamber 122 through the water inlet component 500. Step S22: perform water metering. Specifically, the water inlet component 500 is provided with a flow meter, which can be set on the water inlet pipe 530. During the water inlet process, the amount of water flowing into the cleaning chamber 122 is obtained through the flow meter. Step S23: determine whether the water volume has reached the first set value. If the amount of water entering the cleaning chamber 122 reaches the first set value, then execute step S24: deactivate the water inlet component 500. Close the water inlet valve 600 to stop the water inlet. The value of the first set value is different for different washing items and the number of washing items.

[0113] After completing step S2, the process proceeds to step S3. Specifically, the program performs a logical analysis to determine whether to proceed to the soaking or cleaning process. If the soaking process has already been completed before water injection, the cleaning process proceeds; if the soaking process has not yet been completed, the soaking process proceeds.

[0114] In addition, step S4 can be performed simultaneously with step S2. In step S4: the detergent powder adding process, step S41, step S42, step S43 and step S44 are included.

[0115] Among them, step S41: operate the detergent adding device 300. Specifically, start the motor 330 of the detergent adding device 300, and let the motor 330 drive the feeding screw 340 to rotate to feed the detergent powder. Step S42: measure the detergent powder. Specifically, the number of rotations of the feeding screw 340 can be calculated by calculating the running time of the motor 330, and then the amount of detergent added can be obtained. Step S43: determine whether the amount of detergent powder has reached the second set value. If the amount of detergent powder added has reached the second set value, then execute step S44: deactivate the detergent adding device 300. After receiving the control instruction, the motor 330 of the detergent adding device 300 stops running and stops outputting detergent powder. If the amount of detergent powder added has not yet reached the second set value, continue to add detergent powder.

[0116] After completing the water injection process and the detergent powder process, proceed to step S5: the soaking process. Step 5 includes step S51, step S52, and step S53. Since water is injected into the cleaning chamber 122 and detergent powder is added, the items to be washed are soaked. During the soaking process, it is necessary to execute step S51: soaking timing. Specifically, the electronically controlled drive box 700 is provided with a timer, and the timing function is used to measure the time after completing the water injection and detergent powder addition. Step S52: Determine whether the time measurement reaches the first set time. If the soaking time reaches the first set time, execute step S53: stop the soaking process. After completing the soaking of the items to be washed, there is no need to drain the cleaning chamber 122, and you can proceed to step S6: the cleaning process.

[0117] Step S6 includes steps S61, S62, S63, and S64. Step S61: Activate the ultrasonic vibrator assembly 400 and the circulating pump device 200. Specifically, a control command is transmitted to the ultrasonic vibrator assembly 400 and the circulating pump device 200 to start operation. While ultrasonic cleaning is being performed on the laundry items within the cleaning chamber 122, the laundry items are subjected to high-pressure flushing using the powerful surge generated by the circulating pump device 200. Step S62: Timing. While the ultrasonic vibrator assembly 400 and the circulating pump device 200 are operating, the timer of the electronically controlled drive box 700 operates to calculate the cleaning time. Step S63: Determine whether the cleaning time has reached a second set time duration. If the cleaning time has reached the second set time duration, step S64 is executed: Deactivate the ultrasonic vibrator assembly 400 and the circulating pump device 200. Upon receiving the control command to deactivate operation, the ultrasonic vibrator assembly 400 and the circulating pump device 200 are shut down, completing the cleaning process, and then proceeding to step S7: Draining.

[0118] In step S7, upon receiving the open command, drain valve 133 opens to drain the cleaning chamber 122. Once draining is complete, drain valve 133 closes, and the program proceeds to step S8, which determines whether the number of cleaning cycles has reached a third set value. If the number of cleaning cycles has not yet reached the third set value, the program returns to step S2 and begins the water filling process, supplying the set amount of water to the cleaning chamber 122. If the number of cleaning cycles has reached the third set value, the program proceeds to step S9, terminating the process. At this point, the laundry has been cleaned and can be removed.

[0119] In some embodiments, the control method further comprises the following steps: after powering on the machine, detecting the remaining water level in the wash chamber 122. Specifically, the open / closed state of the drain valve 133 is detected. If the drain valve 133 is closed, the drain valve 133 is opened to drain the remaining water in the wash chamber 122. This prevents residual wastewater from remaining in the wash chamber 122, which could affect the water level in the wash chamber 122 and the washing effect. Simultaneously, the flow signal status of the drain pipe 132 can be monitored using a flow meter. If the flow meter displays zero, the water in the wash chamber 122 has been completely drained. If the drain valve 133 is open, the drain valve 133 is maintained in this state and the water flow signal status of the drain pipe 132 is detected. When the water in the wash chamber 122 has been completely drained, the drain valve 133 is closed. After completing this step, the user can select the corresponding wash program and then proceed to the water filling and detergent powder addition steps.

[0120] During each drainage process, the flow meter on the drain pipe 132 detects the water flow signal status of the drain pipe 132. The drain valve 133 is not closed until the flow meter displays zero. This intelligently determines the closing time of the drain valve 133, effectively reducing the cleaning time of the ultrasonic cleaning tank and helping to improve work efficiency.

[0121] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
