A portion of the cap 430 of the water supply tank 400 is accommodated below the stepped portion 341 a of the receiving portion 341 . In this state, the tip of the outlet portion 433 of the cap 430 protrudes below the receiving portion 341 . Further, the tank receiving member 340 is formed with a rectangular tube-shaped first fitting protrusion 342 protruding downward on the left side of the receiving part 341 , and a square tube-shaped second fitting protrusion 342 on the right side of the receiving part 341 . A protrusion 343 is formed to protrude downward. A coil spring 344 is arranged around the receiving portion 341 and between the tank receiving member 340 and the partition wall 317 . The tank receiving member 340 is held floating from the partition wall 317 that is the bottom surface of the tank housing chamber 318 by the elastic force of the coil spring 344 .

Further, the partition wall 317 is formed with cylindrical left guide portions 317d and right guide portions 317e around the left opening portion 317b and the right opening portion 317c, respectively. The first fitting projection 342 is inserted into the left guide portion 317d, and the second fitting projection 343 is inserted into the right guide portion 317e. The left guide portion 317d and the right guide portion 317e serve as guides when the tank receiving member 340 moves up and down.

The tank receiving member 340 pushes up the water tank 400 to the separated position by the elastic force of the coil spring 344, and when the water tank 400 is pushed downward, it is pushed by the water tank 400 and moves downward. Then, when the water supply tank 400 reaches the insertion position, the first fitting protrusion 342 enters the tank housing chamber 316 through the left opening 317b, and in the tank housing chamber 316, the first fitting concave portion 221 of the water reservoir 200 is inserted. Mates with Similarly, the second fitting protrusion 343 enters the tank housing chamber 316 through the right opening 317 c and fits with the second fitting recess 222 of the water reservoir 200 in the tank housing chamber 316 .

A locking device 350 for locking the water tank 400 at the insertion position is provided in the first fitting protrusion 342 of the tank receiving member 340 . The locking device 350 includes a rod 352 having holding pieces 351 on both sides of its tip, a housing 353 into which the rod 352 moves and moves, and an alternate mechanism (not shown). When the holding piece 351 contacts the claw portion 223 of the first fitting recess 221 of the water reservoir 200 from above, and the rod 352 is pushed into the housing 353 by the claw portion 223, the claw portion 223 is pushed into the holding piece 351 from both sides. , and the rod 352 is held inside the housing 353 by the action of the alternate mechanism. This prevents the claw portion 223 from coming off the locking device 350 . From this state, when the rod 352 is pushed again by the claw portion 223, the holding is released by the action of the alternate mechanism. open. As a result, the claw portion 223 is removed from the lock device 350 .

A tank position detection unit 360 is provided at the rear left position in the lower portion inside the exterior body 310 . As shown in FIGS. 11A and 11B, the tank position detector 360 is positioned below the tank receiving member 340 and includes a microswitch 361 and a switch holder 362. As shown in FIGS. The microswitch 361 detects whether or not the water tank 400 is at the insertion position, that is, whether or not the washing water is being supplied from the water tank 400 . The microswitch 361 corresponds to the detection section of the present invention. The microswitch 361 includes a switch portion 363 and an operation lever 364 for operating the switch portion 363 . The switch holder 362 holds the microswitch 361 and is attached to the first trunk member 311 of the exterior body 310 . The tank receiving member 340 is provided with an operation bar 345 extending toward the microswitch 361 side. The operation bar 345 is provided with an opening 345a.

As shown in FIG. 11(a), when the water tank 400 is in the separated position and the tank receiving member 340 is in the raised state, the operating lever 364 of the microswitch 361 is moved by the lower end of the operating bar 345 to the switch portion 363. The switch portion 363 is pushed in by the operating lever 364 . As a result, an ON signal is output from the microswitch 361 . An elastic force is generated in the operation lever 364 in a direction away from the switch portion 363 . As shown in FIG. 11B, when the water tank 400 is moved to the insertion position and the tank receiving member 340 is pushed down, the operating lever 364 of the microswitch 361 moves away from the switch portion 363 to open the opening of the operating bar 345. 345a and the switch part 363 returns to its original position. As a result, an off signal is output from the microswitch 361 .

An operation panel 370 is provided on the top surface of the exterior body 310 on the right side of the tank inlet 319 . A power button 371 and an operation button 372 are arranged on the operation panel 370 . The power button 371 is an operation button for turning on and off power to the ultrasonic cleaning apparatus 1 . The operation button 372 is an operation button for starting and stopping the cleaning operation.

A control unit 600 is arranged in the lower portion of the main body unit 300 . The control unit 600 includes a microcomputer and the like, and controls the ultrasonic generator 110 . The ON signal and OFF signal output from the microswitch 361 are input to the control unit 600 . Further, an operation signal corresponding to the operation of the operation button 372 is input to the control unit 600 .

<Operation of Ultrasonic Cleaning Device>
Next, the operation of the ultrasonic cleaning device 1 will be described.

When the cleaning operation is not performed, as shown in FIG. 6, the water supply tank 400 is held at the separated position in the tank housing chamber 318 by pushing up the tank receiving member 340 . At this time, the valve body 441 of the water supply tank 400 is in a closed state, and the wash water is not discharged from the water supply tank 400 . Moreover, the top surface of the water tank 400 protrudes above the top surface of the main body 300, and the top surface cover 420 of the water tank 400 is exposed to the outside. In this state, the user can take out the water supply tank 400 to the outside by grasping the handle portion 421 with fingers.

When performing the cleaning operation, if there is no cleaning water in the water supply tank 400 , the user takes out the water supply tank 400 to the outside, turns it upside down, and opens the cap 430 . The user fills the water supply tank 400 with water up to the position of the first scale 414, then puts the liquid detergent up to the position of the second scale 415, closes the cap 430, and shakes the water supply tank 400 lightly to mix the liquid detergent and the water. and mix. Thereby, washing water is generated in the water supply tank 400 . After that, the user inserts the water tank 400 into the main body 300 again.

The user presses the top surface cover 420, that is, the top surface of the water tank 400 with a finger to push the water tank 400 downward. Water tank 400 and tank receiving member 340 descend against the elastic force of coil spring 344, and water tank 400 reaches the insertion position. As shown in FIG. 7, the discharge port 433 enters the tank storage chamber 316 together with the receiving part 341 through the central opening 317a, and the discharge port 401 of the water tank 400 is inserted into the water tank 250. As shown in FIG. In addition, the first fitting protrusion 342 and the second fitting protrusion 343 enter the tank storage chamber 316 through the left opening 317b and the right opening 317c, respectively, and the first fitting recess 221 and the second fitting recess 221 enter. It fits with the joint recess 222 . As a result, the water storage part 200 cannot be pulled out forward, and the water storage part 200 cannot be removed from the mounting base 320 , that is, the main body part 300 . On the other hand, between the first fitting protrusion 342 and the first fitting recess 221, the locking device 350 exhibits a locking function. That is, the claw portion 223 of the water storage portion 200 is pushed into the housing 353 while being held by the holding piece 351 , so that the water storage portion 200 cannot be removed from the locking device 350 . As a result, the tank receiving member 340 cannot be lifted by the elastic force of the coil spring 344, so that the water tank 400 is retained at the insertion position.

When the water tank 400 is lowered to the insertion position, the pin 442 of the water tank 400 collides with the protrusion 252 of the water tank 250 and is pushed up against the pressing force of the coil spring 443 . As a result, the valve body 441 is separated from the outflow port 431 to open the outflow port 431 , and the wash water in the water supply tank 400 is discharged from the discharge port 401 . The discharged wash water is received by the water supply tank 250 and sent to the water tank 240 through the water supply channel 253 . When flushing water accumulates in the water tank 240, the water level in the water tank 240 and the water level in the water supply tank 250 rise. 4, when the water level in the water supply tank 250 rises to the height of the discharge port 401 of the water supply tank 400 and the discharge port 401 is blocked by the cleaning water, the air pressure in the water supply tank 400 and the external Water supply from the water supply tank 400 stops while the valve body 441 remains open due to the balance with the air pressure. Even if the washing water splashes out of the water supply tank 250 due to water splashing or the like during the supply of water, the washing water that jumps out is collected by the outer tank 260, so that the washing water leaks out of the water reservoir 200. Hard to get out.

When the washing water is stored in the water tank 240, the user moves the dirty part of the object to be washed, for example, the collar part of a dress shirt, onto the water tank 240, that is, the vibration of the water tank 240 and the ultrasonic wave generator 110. It is set between the horn 112. The object to be washed is immersed in the washing water stored in the water tank 240, and the washing water permeating the inside of the object to be washed 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. When the object to be washed absorbs water, the water level in the water tank 240 drops, the water level in the water supply tank 250 drops, and the outlet 401 of the water tank 400 is no longer blocked by the cleaning water. Washing water is replenished from the water supply tank 400 into the water supply tank 250, ie, the water tank 240, until the water supply tank 240 is filled with the washing water again. As a result, the water level in the water tank 240, that is, the amount of water, is maintained at an appropriate level.

The user presses the run button 372 to start the cleaning run.

When the water tank 400 is in the insertion position and the washing water is being supplied from the water tank 400 , this state is detected by the microswitch 361 and an off signal is output from the microswitch 361 to the control unit 600 . In this case, the control unit 600 energizes the ultrasonic transducer 111 to operate the ultrasonic generator 110 . This starts the cleaning operation.

When the water supply tank 400 is not at the insertion position, that is, at the separated position, and the washing water is not being supplied from the water supply tank 400, this state is detected by the microswitch 361, and the microswitch 361 is sent to the controller 600. ON signal is output to In this case, the control unit 600 does not energize the ultrasonic transducer 111 and does not operate the ultrasonic generator 110 . Therefore, the washing operation is not started when washing water is not supplied to the water tank 240 .

FIGS. 12(a) to 12(c) are diagrams for explaining how the ultrasonic cleaning apparatus 1 according to the present embodiment removes stains from the object to be cleaned.

When the ultrasonic wave generator 110 operates, ultrasonic waves are generated from the tip of the vibration horn 112, and the ultrasonic vibrations are transmitted to the cleaning water inside the object to be cleaned through the cleaning water around the vibration horn 112. FIG. As shown in FIG. 12(a), 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. Next, as shown in FIG. 12(b), the pressure in the cavity is increased, and when 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. 12(c), the ultrasonic vibration from the vibrating horn 112 produces a water flow from the inside of the object to be cleaned into the water tank 240, and this water flow causes the dirt separated from the object to be cleaned to be stored. It is discharged into tank 240 . In the water tank 240, convection occurs due to the above water flow, so dirt is easily separated from the object to be washed. Furthermore, the action of the detergent contained in the washing water also makes it easier to separate dirt from the object to be washed, and makes it difficult for the dirt to reattach to the object to be washed. In this way, dirt is removed from the items to be cleaned.

The user moves the object to be cleaned mainly in the horizontal direction in order to bring the dirty portion of the object to be cleaned 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 300, 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 part 200 is attached to the main body part 300, it is difficult for the water storage part 200 to move together with the object to be washed when the user moves the object to be washed. Furthermore, since the left and right side surfaces of the water tank 240 are inclined surfaces 242, the user can smoothly move the object to be washed by moving the object to be washed along both the inclined surfaces 242 and the bottom surface 241. can. In particular, since the inclined surface 242 is a curved surface whose inclination becomes gentler as it approaches the bottom surface 241, it is possible to move the object to be cleaned more smoothly.

When the washing of the object to be washed is completed, the user presses the operation button 372 again. The operation of the ultrasonic wave generator 110 is stopped by the control unit 600, and the cleaning operation is terminated. After that, the user slightly pushes the water supply tank 400 downward with a finger. The tank receiving member 340 is lowered slightly together with the water supply tank 400, and the first fitting protrusion 342 is lowered slightly. Then, when the finger is released from the water tank 400 , the locking device 350 is released from the holding of the holding piece 351 and the claw portion 223 is released from the locking device 350 . As a result, the fixing by the locking device 350 is released, and the elastic force of the coil spring 344 raises the tank receiving member 340, which lifts the tank receiving member 340 and moves the water tank 400 to the separated position. The pin 442 moves downward, the outflow port 431 is closed by the valve body 441, and the water supply from the water supply tank 400 is stopped.

When the water tank 400 is pushed in as described above and the tank receiving member 340 is pushed up to move the water tank 400 to the separated position during the cleaning operation, the microswitch 361 outputs an ON signal. . Since it is assumed that the water supply from the water supply tank 400 cannot be performed normally, the control unit 600 automatically stops the washing operation. Here, when the water supply tank 400 is at the insertion position, the top surface of the water supply tank 400 is flush with the top surface of the body portion 300 and does not protrude above the top surface of the body portion 300, as shown in FIG. . As a result, the user cannot pick up the water tank 400 with his or her fingers and cannot perform an operation such as pulling up the water tank 400 . As a result, when the tank receiving member 340 is in the lowered state and the water tank 400 is detected by the microswitch 361 as being in the insertion position, the water tank 400 alone is less likely to be lifted and removed. Therefore, it is unlikely that the washing operation is continued while water is not supplied from the water supply tank 400 .

When the tank receiving member 340 rises together with the water tank 400 , the first fitting protrusion 342 and the second fitting protrusion 343 are separated from the first fitting recess 221 and the second fitting recess 222 . As a result, the water reservoir 200 can be detached from the mount 320 , that is, the main body 300 .

After finishing the cleaning operation, the user presses the operation button 281 . As shown by the dashed line in FIG. 8, when the operation button 281 is pushed down, the valve body 283 moves downward together with the operation pin 282, the valve body 283 is separated from the drain port 271, and the drain port 271 is opened. Washing water stored in the water tank 240 and the water supply tank 250 is drained through the drain port 271 . Drainage from the drainage port 271 flows into the drainage container 500 through the opening 521 and is accumulated in the drainage container 500 . The user releases the operation button 281 when all the washing water is discharged from the water tank 240 and the water supply tank 250 . Due to the elastic force of the coil spring 284 , the valve body 283 moves upward together with the operating pin 282 to close the drain port 271 .

The user holds the handle portion 511 and pulls out the drainage container 500 forward in the detachment direction, and removes the drainage container 500 from the water storage portion 200 as shown in FIG. When the drainage container 500 is pulled out forward, the water reservoir 200 may also be subject to a forward force, which is the detachment direction. However, the forward movement of the water reservoir 200 is blocked by the movement blocking mechanism M. As shown in FIG. Thereby, it is possible to prevent the water storage part 200 from coming off from the main body part 300 when the user tries to detach the drainage container 500 . The user carries the removed drainage container 500 to a place such as a washbasin where it can be discarded, and discards the cleaning water collected in the drainage container 500 .

The drainage container 500 has a structure in which the lid 520 is fitted inside the container body 510 from above, and the user can remove the lid 520 upward from the container body 510 by, for example, hooking the opening 521 with a finger. can. This allows the user to wash the inside of the container body 510 with the lid 520 removed.

Moreover, when the user cleans the water storage unit 200, that is, the water storage tank 240 and the water supply tank 250, the water storage unit 200 is removed from the main body 300 as shown in FIG. At this time, the user first slightly lifts the front side of the water reservoir 200 as a release operation. The water storage part 200 slightly rotates around the shaft part 213 . As a result, in the movement blocking mechanism M, the engagement between the claw portion 233 of the hook portion 232 and the rib 323 is released. The user moves the water storage unit 200 forward while tilting it until the claws 233 are positioned in front of the ribs 323, and then restores the posture of the water storage unit 200 and continues the movement. Thus, the water storage part 200 is separated from the main body part 300 . The user carries the removed water storage unit 200 to a washroom or the like, and cleans the water storage tank 240 and the water supply tank 250 . Further, the user can remove the water storage unit 200 while leaving the cleansing water in the water tank 240 and the water supply tank 250, so that the cleansing water can be discarded and the water storage unit 200 can be cleaned at the same time.

Here, it is conceivable that the user may erroneously try to start the cleaning operation with the water storage unit 200 removed, and the water supply tank 400 may be pushed into the insertion position. In this case, even if the tank receiving member 340 is pushed down together with the water supply tank 400 , the claw portion 223 provided on the water storage portion 200 does not exist in the tank housing chamber 316 , so the claw portion 223 is held by the lock device 350 . Therefore, the locking function of the locking device 350 is not exhibited. Therefore, the water supply tank 400 cannot stay at the inserted position and is returned to the separated position.

<Effects of this embodiment>
As described above, according to the present embodiment, since the ultrasonic cleaning unit 100 is held by the main body 300, the user can hold the object to be cleaned with both hands. Thereby, the user can smoothly move the object to be cleaned. In addition, since the water storage part 200 is attached to the main body part 300, the water storage part 200 is unlikely to move together with the object to be cleaned when the object to be cleaned is moved, which prevents water from spilling out of the water storage part 200. Hard to happen. In addition, the wastewater from the water tank 240 and the like can be stored in the wastewater container 500, and the wastewater container 500 can be separated from the water storage unit 200 and the main unit 300, so it is easy to dispose of the washing water after use. can be done

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, the user can easily drain the washing water from the water tank 240 or the like to the drainage container 500 by simply pressing the operation button 281 .

Furthermore, according to this embodiment, since the drainage container 500 is provided in the water storage part 200, the drainage path from the water storage tank 240 or the like to the drainage container 500 can be shortened, and the drainage to the drainage container 500 can be performed smoothly. becomes.

Furthermore, according to the present embodiment, water storage section 200 can be removed from main body section 300 . As a result, the water tank 240 and the like can be easily cleaned. It is also possible to directly dispose of the wash water remaining in the water tank 240 or the like without discharging it into the drainage container 500 .

Furthermore, according to the present embodiment, the drainage container 500 and the water storage part 200 are separated in the same direction, so that the user can easily handle the drainage container 500 and the water storage part 200 . Moreover, the movement blocking mechanism M can prevent the water storage part 200 from moving in the detachment direction as the drainage container 500 moves in the detachment direction. Moreover, it is possible to prevent the water storage part 200 from coming off from the main body part 300 .

Furthermore, according to the present embodiment, when the cleaning water is not being supplied from the water supply tank 400, the ultrasonic wave generator 110 does not operate and the cleaning operation is not performed. Therefore, it is possible to prevent unnecessary cleaning operation.

Furthermore, according to this embodiment, since the water tank 240 has the inclined surfaces 242 on both the left and right sides of the bottom surface 241, the user can move the dirty portion of the object to be cleaned to the tip position of the ultrasonic wave generator 110. The object to be washed can be smoothly moved in the left-right direction. Thereby, the user can easily wash the object to be washed.

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. .

Coil spring 740 is arranged between front reservoir member 210 and arm portion 722 . The slide lever 720 is pushed rearward by the elastic force of the coil spring 740. In the pushed rearward state, the rear ends of the left and right arm portions 722 are positioned inside the first fitting recess 221 of the rear water storage member 220 and inside the first fitting recess 221, respectively. 2 exposed in the fitting recess 222 (see FIG. 14(b)).

FIGS. 15(a) and 15(b) are diagrams for explaining the operation of the opening prevention mechanism 700 according to the modification.

As shown in FIG. 15(a), when the tank receiving member 340 is raised because the water tank 400 is in the separated position, the slide lever 720 is in the rear position. The button stopper 710 is located at the lower position with the shaft portion 712 guided by the front end portion of the cam hole 721 . In this state, the stop pin 711 is far away from the back surface of the operation button 281 . As a result, the operation button 281 can be pushed downward, and the water can be drained from the water tank 240 or the like. At this time, as described above, the rear ends of the left and right arm portions 722 are exposed inside the first fitting recess 221 and the second fitting recess 222, respectively.

Move to forward position. The shaft portion 712 of the button stopper 710 is guided by the rear end portion of the cam hole 721 and moves to the upper position. In this state, the stop pin 711 is positioned near the back surface of the operation button 281 . As a result, since the stop pin 711 is hit, the operation button 281 cannot be pushed downward, and water cannot be drained from the water tank 240 or the like.

As described above, in this modified example, when the water tank 400 is in the insertion position and the washing water is being supplied from the water tank 400 to the water tank 240, the water tank 240 is not drained. Therefore, it is possible to prevent wasteful use of the wash water in the water tank 400 by draining the water from the water tank 240 due to an erroneous operation of the operation button 281 .

<Other modification examples>
In the above-described embodiment, the water stored in the water supply tank 400 and supplied to the water tank 240 is water containing detergent, but may be water containing no detergent. In this case, when performing the cleaning operation, it is preferable that the detergent is applied in advance to the soiled portion of the object to be cleaned.

Moreover, in the above embodiment, the water storage part 200 is detachably attached to the main body part 300 . However, the water storage part 200 may not be removable from the main body part 300 . For example, the water reservoir 200 may be integrated with the main body 300 by being integrated with the mounting base 320 .

Furthermore, in the above embodiment, the drainage container 500 is detachably provided in the water reservoir 200 . However, the drainage container 500 may be detachably provided on the main body 300 . For example, the drainage container 500 may be detachably attached to the front surface of the mounting base 320 .

Furthermore, in the above-described embodiment, the housing 130 of the ultrasonic cleaning section 100 is configured as a separate member from the main body section 300 . However, the housing 130 may be integrally formed with the body portion 300 .

Furthermore, in the above-described embodiment, the movement blocking mechanism M is configured such that the engagement between the claw portion 233 of the hook portion 232 and the rib 323 is released by the operation of tilting the water storage portion 200 . However, the configuration of the movement blocking mechanism M is not limited to the above. For example, the hook portion 232 is configured to be movable. A configuration in which the engagement is released may be employed.

Furthermore, in the above-described embodiment, the drainage mechanism 280 is configured such that the operation pin 282 moves downward as the operation button 281 is pushed, and the valve body 283 moves away from the drainage port 271 to open the drainage port 271. be. However, the configuration for opening and closing the drain port 271 is not limited to the above. For example, an electromagnetic valve that can be opened and closed is provided at the drain port 271, an input circuit receives the operation of the operation button 281, and the controller 600 opens and closes the electromagnetic valve based on an operation signal from the input circuit. may

Furthermore, in the above embodiment, the microswitch 361 indirectly detects through the tank receiving member 340 that the water tank 400 is at the insertion position when the operation bar 345 of the tank receiving member 340 comes into contact with the microswitch 361 . However, by configuring a portion of the water tank 400 to contact the microswitch 361, the microswitch 361 may directly detect that the water tank 400 is in the insertion position.

Furthermore, the water supply structure for supplying water from the water supply tank 400 to the water tank 240 is not limited to the configuration of the above embodiment, and other water supply structures may be employed. Further, the water tank 400 may not be provided in the ultrasonic cleaning apparatus 1, and water may be directly supplied to the water tank 240 from a container or tap provided by the user.

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.
