JP 2004-216244 A

In the above ultrasonic cleaning apparatus, the cleaning apparatus main body and the tray are separate and independent, and the user must hold the cleaning apparatus main body with one hand and the object to be cleaned with the other hand. For this reason, it may be difficult to move the object to be cleaned according to the location of the dirt when it is held with only one hand. In addition, the tray is simply placed on a table or other installation location, and when the object is moved, the tray tends to move together with the object to be washed, and there is a risk that the tray may tilt and leak water.

Therefore, there is concern that it will be difficult for the user to smoothly clean the object to be cleaned using the ultrasonic cleaning apparatus.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an ultrasonic cleaning apparatus that allows a user to smoothly clean an object to be cleaned and that can improve convenience for the user.

An ultrasonic cleaning apparatus according to a main aspect of the present invention includes an ultrasonic cleaning unit including an ultrasonic generator that generates ultrasonic waves, a main unit installed at an installation location and holding the ultrasonic cleaning unit, and the main unit. a water storage recess that is provided below the ultrasonic generator in the part and stores water for immersing the object to be cleaned; It comprises a water supply tank to be filled , a drain port provided in the water storage recess, a drain valve mechanism for opening and closing the drain port, and a drain container for storing water discharged from the drain port . The water supply tank includes a discharge port for supplying water to the water storage recess, and is attached to the main body with the discharge port facing downward when supplying water to the water storage recess. The drain valve mechanism is connected to a drain valve for closing the drain port, and is connected to the drain valve, and is pushed into the water tank when the water tank is attached to the main body with the discharge port facing upward. and an actuating member operable to move the drain valve in a direction in which the drain port is opened.

According to the above configuration, since the ultrasonic cleaning section is held by the main body, the user can hold the object to be cleaned with both hands. Thereby, the user can smoothly move the object to be cleaned. Further, since the water storage recess is provided in the main body, the water storage recess is less likely to move together with the object to be cleaned when the object is moved, and water is less likely to spill out of the water storage recess. Furthermore, since water is automatically supplied from the water supply tank to the water storage recess, the user does not need to replenish the water storage recess each time the water in the water storage recess decreases.

According to the above configuration, the water is drained from the water storage recess when the water supply tank is attached to the main body in the opposite direction to when water is supplied. Therefore, the water can be drained from the water storage recess after the water is not supplied from the water supply tank to the water storage recess, thereby preventing simultaneous water supply and drainage.

The tank receiving member 224 has a circular socket 225 that is concentric with the center of the protrusion 524 .

FIG. 6 is a longitudinal sectional view of water supply tank 300 according to the present embodiment.

Water supply tank 300 includes a tank body 310 and a cap 320 . Tank body 310 and cap 320 are made of, for example, a resin material. The cap 320 is provided with a water supply valve mechanism 330 .

The tank body 310 is a cylindrical transparent container with a closed upper end surface 310a and a lower end surface 310b. A water inlet/outlet 311 is formed in the center of the lower end surface 310b of the tank body 310, and a cylindrical connection port 312 is provided around the inlet/outlet 311 so as to protrude downward. The outer diameter of the tank body 310 is approximately equal to the inner diameters of the upper opening 221 and the lower opening 223 of the upper exterior body 220 .

The cap 320 is attached to the connection opening 312 by a screw method to cover the entrance/exit 311 . The cap 320 has a closing wall portion 321 that closes the inlet/outlet 311 at its intermediate portion, and a water-sealing packing 340 is sandwiched between the closing wall portion 321 and the connection port portion 312 . An outflow port 322 is formed in the blocking wall portion 321 . A boss 323 having a hole 323a is provided at the center of the outflow port 322 . Both sides of boss 323 are connected to the periphery of outlet 322 by two ribs (not shown). A distal end portion 320 a of the cap 320 has a smaller outer diameter than other portions of the cap 320 . The outer diameter of the tip portion 320 a of the cap 320 is made substantially equal to the inner diameter of the socket portion 225 of the tank receiving member 224 .

The water supply valve mechanism 330 includes a water supply valve 331 , a water supply pin 332 and a coil spring 333 . The water supply valve 331 is made of an elastic material such as rubber. The water supply pin 332 is made of a metal material or a resin material, and is passed through the hole 323a of the boss 323 so as to be vertically movable. A water supply valve 331 is attached to the upper end of the water supply pin 332 . A lower end portion of the water supply pin 332 has a larger outer diameter than other portions to form a flange portion 332a, and a coil spring 333 is arranged between the flange portion 332a and the boss 323. The coil spring 333 is in a compressed state, the water supply pin 332 is pushed downward by the coil spring 333 , and the water supply valve 331 closes the outflow port 322 .

When the water supply pin 332 is pushed from below and moves upward against the pressing force of the coil spring 333, the water supply valve 331 moves away from the outflow port 322 and the outflow port 322 is opened. As a result, water is discharged from inside the tank main body 310 , that is, inside the water supply tank 300 . When the pressure from below the water supply pin 332 is released, the water supply pin 332 moves downward, and the water supply valve 331 closes the outflow port 322 . As a result, the discharge of water from inside the water supply tank 300 is stopped. When replenishing the water supply tank 300 with water, the cap 320 is removed and water is poured into the tank main body 310 through the inlet/outlet 311 .

The outlet of the cap 320 becomes the final water outlet 301 in the water tank 300 . The outer diameter of the cap 320 is smaller than the outer diameter of the tank main body 310, and the water supply tank 300 as a whole has the shape of a bottomed cylindrical container with the portion near the outlet 301 constricted inward.

When the cleaning operation is not performed and water is not stored in the water storage recess 500, the ultrasonic cleaning apparatus 1 is configured such that the water supply tank 300 is removed from the main body 200, as shown in FIGS. is in good condition.

FIG. 7 is a front cross-sectional view of ultrasonic cleaning apparatus 1 according to the present embodiment, in which water supply tank 300 is attached to main body 200 with outlet 301 facing downward. FIG. 8 is a front cross-sectional view of ultrasonic cleaning apparatus 1 according to the present embodiment, in which water supply tank 300 is attached to main body 200 with outlet 301 facing upward.

When starting the cleaning operation, the user mounts the water supply tank 300 on the upper exterior body 220, that is, the main body 200, with the discharge port 301 facing downward, in order to supply water to the water storage recess 500. FIG. As shown in FIG. 7 , the water supply tank 300 has a tank main body 310 passed through the upper opening 221 and the lower opening 223 of the upper exterior body 220 and the cap 320 is received by the tank receiving member 224 . As a result, the water supply tank 300 is set at a position where water can be supplied inside the upper exterior body 220 .

The distal end portion 320 a of the cap 320 passes through the socket portion 225 and enters the water supply tank 520 , and the discharge port 301 of the water supply tank 300 is inserted into the water supply tank 520 . Also, the water supply pin 332 of the water supply tank 300 collides with the protrusion 524 of the water supply tank 520 and is pushed up. As a result, the water supply valve 331 is opened and the water in the water supply tank 300 is discharged from the discharge port 301 . The discharged water is received in water supply tank 520 and sent to immersion tank 510 through water supply channel 530 . When water accumulates in the immersion tank 510, the water level in the immersion tank 510 and the water level in the water supply tank 520 rise. 7, when the water level in the water supply tank 520 rises to the level of the discharge port 301 of the water supply tank 300 and the discharge port 301 is blocked with water, the air pressure in the water supply tank 300 and the air pressure outside the water supply tank 300 , the water supply from the water supply tank 300 stops while the water supply valve 331 remains open.

Note that the drain pin 542 is positioned inside the tank body 310 but outside the cap 320 when viewed from above. Also, the position of the upper end of the drain pin 542 is lower than the position of the lower end surface 310b of the tank body 310 . Therefore, the water supply tank 300 does not contact the drain pin 542 and the drain valve 541 keeps the drain port 521 closed.

When water is stored in the immersion tank 510 , the user can place a dirty part of the object to be cleaned, for example, the collar of a shirt, on the immersion tank 510 , i.e., the vibration horn of the immersion tank 510 and the ultrasonic wave generator 110 . 112. At this time, a detergent may be applied in advance to the soiled portion of the object to be washed. The object to be cleaned is immersed in the water stored in the immersion tank 510, and the water permeating the inside of the object to be cleaned seeps out to the surface. A thin water layer is formed on the surface of the object to be cleaned, and the vibrating horn 112 comes into contact with this water layer. As the object to be washed absorbs water, the water level in the immersion tank 510 drops and the water level in the water supply tank 520 drops. Water is supplied from the water supply tank 300 into the water storage recess 500 until the water storage recess 500 is filled with water. As a result, the water level in the immersion tank 510, that is, the amount of water, is maintained at an appropriate level.

When the user performs a predetermined start operation and the cleaning operation is started, the ultrasonic vibrator 111 is energized and the ultrasonic wave generator 110 is activated.

FIGS. 9A to 9C are diagrams for explaining how the ultrasonic cleaning apparatus 1 according to the present embodiment removes stains from an object to be cleaned.

When the ultrasonic wave generator 110 operates, ultrasonic waves are generated from the tip of the vibrating horn 112, and the ultrasonic vibrations are transmitted to the water inside the object to be cleaned through the water around the vibrating horn 112. As shown in FIG. 9A, inside the object to be cleaned, pressure reduction and pressure are alternately generated by the action of ultrasonic vibration, and vacuum cavities are generated in portions where the pressure is low. In other words, a large number of cavities exist in the dirty portion of the object to be washed. As shown in FIG. 9(b), when the pressure in the cavity is increased and the cavity is crushed by this pressure and the cavity is destroyed, a shock wave is generated in the dirty part of the object to be cleaned. Dirt is separated from the object to be cleaned by this shock wave. As shown in FIG. 9(c), the ultrasonic vibration from the vibrating horn 112 produces a water flow from the interior of the object to be cleaned into the immersion bath 510, and the water flow immerses the dirt separated from the object to be cleaned. It is discharged into tank 510 . In the immersion bath 510, convection occurs due to the water current, so dirt is easily separated from the object to be cleaned. In this way, dirt is removed from the items to be cleaned.

A user needs to move the object to be cleaned in order to bring the dirty portion of the object to the position of the ultrasonic wave generator 110 . In the ultrasonic cleaning apparatus 1 of the present embodiment, since the ultrasonic cleaning unit 100 is held by the main body 200, the user does not have to hold the ultrasonic cleaning unit 100 by hand, and the object to be cleaned is held by both hands. can have This allows the user to move the object to be cleaned more smoothly than when holding it with one hand. Moreover, since the water storage recess 500 is provided in the main body 200, it is unlikely that the water storage recess 500 moves together with the object to be cleaned when the user moves the object to be cleaned.

When the washing of the object to be washed is completed, the user performs a predetermined stop operation. The operation of the ultrasonic generator 110 is stopped and the cleaning operation is terminated. After that, the user lifts up the water tank 300 and removes it from the main body 200 . The pressing of the water supply pin 332 by the protrusion 524 is released, the water supply valve 331 is closed, and water is no longer discharged from the water supply tank 300 .

Next, the user attaches the water supply tank 300 to the upper exterior body 220, that is, the main body 200, with the outlet 301 facing upward in order to drain water from the water storage recess 500. FIG. As shown in FIG. 8 , the water supply tank 300 is received by the tank receiving member 224 at the upper end surface 310 a of the tank body 310 . As a result, the water supply tank 300 is set at a position in which the water can be drained inside the upper exterior body 220 .

The upper end surface 310 a of the water supply tank 300 collides with the drain pin 542 , and the drain pin 542 is pushed down against the pressing force of the coil spring 543 . As a result, the drain valve 541 moves downward and away from the drain port 521 to open the drain port 521 . The water in the water storage recess 500 is discharged through the drain port 521 and stored in the drain container 400 . At this time, the bottom surface of the water supply tank 520 is lower than the bottom surface of the immersion tank 510, and the bottom surface of the water supply channel 530 is inclined downward from the immersion tank 510 toward the water supply tank 520. It easily flows into the inner drain port 521 . As a result, water is smoothly drained from the water storage recess 500 .

When the water is drained from the water storage recess 500 , the user lifts up the water supply tank 300 and removes it from the main body 200 . The capacity of the drainage container 400 can be set to a capacity that allows the water in the water storage recess 500 to be stored multiple times. For example, when the water in the drainage container 400 is almost filled with water, the user pulls out the drainage container 400 from the main body 200 to remove the drainage container 400, and pours the water in the drainage container 400 into the drain port of the washstand or the like. in a suitable place for disposal. After that, the user puts the drainage container 400 back into the main body 200 .

<Effects of this embodiment>
As described above, according to the present embodiment, since the ultrasonic cleaning unit 100 is held by the main body 200, the user can hold the object to be cleaned with both hands. Thereby, the user can smoothly move the object to be cleaned. Further, since the water storage recess 500 is provided in the main body 200, the water storage recess 500 is unlikely to move together with the object to be cleaned when the object to be cleaned is moved. Hard to happen. Further, the main body 200 is provided with a water tank 300, and water is automatically supplied from the water tank 300 to the water storage recess 500 during the cleaning operation. It becomes unnecessary to perform the work of replenishing water in 500.

As described above, according to the present embodiment, the user can smoothly clean the object to be cleaned using the ultrasonic cleaning apparatus 1, and an improvement in convenience for the user can be expected.

Further, according to the present embodiment, when the water supply tank 300 is attached to the main body 200 with the discharge port 301 facing upward, the water drain pin 542 is pushed by the water supply tank 300 and actuated, thereby 521 is opened, and when the water supply tank 300 is attached to the main body 200 in the opposite direction to the water supply, the water storage recess 500 is drained. Therefore, after the water supply tank 300 stops supplying water to the water storage recess 500, water can be drained from the water storage recess 500, thereby preventing water supply and drainage from being performed at the same time.

Furthermore, according to the present embodiment, since the drain pin 542 is arranged inside the main body 200, the drain pin 542 is operated when water is supplied from the water supply tank 300, and the drain port 521 is opened. Situations are unlikely to occur.

Furthermore, according to the present embodiment, the drainage container 400 can be removed from the main body 200, so that the water in the drainage container 400 can be easily discarded.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and the embodiments of the present invention can be modified in various ways other than those described above. .

For example, in the above-described embodiment, the housing 130 of the ultrasonic cleaning section 100 is configured as a separate member from the upper exterior body 220 of the main body section 200 . However, the housing 130 may be integrally formed with the upper exterior body 220 . Similarly, the lower exterior body 210 and the upper exterior body 220 may be integrally formed.

Further, the water supply structure for supplying water from the water supply tank 300 to the water storage recess 500 is not limited to the configuration of the above embodiment, and other water supply structures may be employed.

Furthermore, in the above embodiment, the water storage recess 500 is divided into the immersion tank 510 , the water supply channel 530 and the water supply tank 520 . However, the water storage recess 500 may have a shape that does not clearly separate the immersion tank 510, the water supply channel 530, and the water supply tank 520, such as an elliptical shape elongated in the front-rear direction. In this case, in the water storage recess 500, the area exposed from the upper exterior body 220 in which the object to be cleaned is immersed becomes the immersion tank 510, and the area in the upper exterior body 220 to which the water supply tank 300 is connected becomes the water supply tank 520. The water supply channel 530 disappears.

Furthermore, in the above embodiment, the top surface of the drainage container 400 is open. may be taken. This makes it difficult for the water in the drainage container 400 to leak out to the outside even if the drainage container 400 is somewhat roughly handled when the drainage container 400 is removed.

In addition, the embodiments of the present invention can be appropriately modified in various ways within the scope of the technical idea indicated in the scope of claims.
