The lower end portion of the pin 442 is larger than the outer diameter of the other portion to constitute the flange portion 442a, and a coil spring 443 is disposed between the flange portion 442a and the projection 432. The coil spring 443 is in a compressed state, the pin 442 is pressed downward by the coil spring 443, and the valve body 441 closes the outflow port 431.

A cylindrical discharge port portion 433 is formed on the outer bottom surface of the cover 430 so as to surround the pin 442. The outlet of the outlet portion 433 is the discharge port 401 of the final water of the water supply tank 400, that is, the washing water.

A tank inlet port 319 is provided on the top surface of the exterior body 310. The tank inlet 319 has a shape corresponding to the outer shape of the top cover 420 of the water supply tank 400. The water supply tank 400 is housed in the tank accommodating chamber 318 through the tank inlet port 319.

A tank holding member 330 made of resin is provided in the tank accommodating chamber 318. The water tank holding member 330 is constituted by a first holding member 331 which is a transparent member surrounding the periphery of the water supply tank 400, and a second holding member 332 which supports the upper portion, the lower portion and the back portion A member that holds the member 331. The upper end portion of the first holding member 331 is connected to the tank inlet port 319. The water supply tank 400 is held by the water tank holding member 330 in such a manner as to be movable between the separated position and the insertion position, wherein the separation position is a position where the discharge port 401 is away from the water supply tank 250 as shown in FIG. 6, and the insertion position is as shown in FIG. The discharge port 401 shown is inserted into the position of the water supply tank 250.

Since the second body member 312, the first holding member 331, and the tank main body 410 are transparent, the user can confirm the remaining amount of the washing water in the water supply tank 400 from the outside. The second body member 312, the first holding member 331, and the tank main body 410 have a transparency in which the user can visually measure the remaining amount of the washing water, and may also be colored.

A water tank receiving member 340 made of resin is provided in a lower portion of the tank accommodating chamber 318. A cylindrical receiving portion 341 is formed at a central portion of the tank receiving member 340. In the receiving portion 341, the intermediate portion has a step portion 341a, and the outer diameter of the lower portion of the step portion 341a is small. A portion of the lid 430 of the water supply tank 400 is housed below the step portion 341a of the receiving portion 341. In this state, the distal end portion of the discharge port portion 433 of the cover 430 protrudes downward from the receiving portion 341. Further, in the tank receiving member 340, the rectangular tubular first fitting projection 342 is formed on the left side of the receiving portion 341 so as to protrude downward, and the square tubular second fitting projection 343 protrudes downward. The form is formed on the right side of the receiving portion 341. A coil spring 344 is disposed around the receiving portion 341 between the tank receiving member 340 and the partition wall 317. The water tank receiving member 340 is maintained in a state of being floated from the partition wall 317 which is the bottom surface of the water tank accommodating chamber 318 by the elastic force of the coil spring 344.

In the partition wall 317, a central opening portion 317a and a left opening portion 317b connected to the groove accommodating chamber 316 are formed at positions corresponding to the receiving portion 341, the first fitting protruding portion 342, and the second fitting protruding portion 343, respectively. Right opening portion 317c. Further, in the partition wall 317, a cylindrical left guide portion 317d and a right guide portion 317e are formed around the left opening portion 317b and the right opening portion 317c, respectively. The first fitting protrusion 342 is inserted into the left guiding portion 317d, and the second fitting protrusion 343 is inserted into the right guiding portion 317e. The left guide portion 317d and the right guide portion 317e are guides when the tank receiving member 340 moves up and down.

The water tank receiving member 340 pushes the water supply tank 400 up to the separated position by the elastic force of the coil spring 344, and when the water supply tank 400 is pushed downward, the tank receiving member 340 is pushed downward by the water supply tank 400. Then, when the water supply tank 400 reaches the insertion position, the first fitting protrusion 342 enters the groove accommodating chamber 316 through the left opening portion 317b, and fits into the first fitting recess 221 of the water storage portion 200 in the groove accommodating chamber 316. . Similarly, the second fitting projection 343 enters the groove accommodating chamber 316 through the right opening portion 317c, and is fitted into the second fitting recess 222 of the water storage portion 200 in the groove accommodating chamber 316.

Inside the first fitting protrusion 342 of the water tank receiving member 340, a locking device 350 for pre-locking the water supply tank 400 to the insertion position is provided. The lock device 350 includes a lever 352 having a holding piece 351 on both sides of the distal end portion, a housing 353 through which the rod 352 enters and exits, and an alternate mechanism (not shown). When the holding piece 351 abuts against the claw portion 223 of the first fitting recess 221 of the water storage portion 200 from above, and the rod 352 is pushed into the inside of the outer casing 353 by the claw portion 223, the claw portion 223 is caught by the holding piece 351 from both sides. Live, and the rod 352 is held inside the outer casing 353 by the action of an alternating mechanism. Thereby, the claw portion 223 is not detached from the lock device 350. When the lever 352 is pushed in again by the claw portion 223 from this state, the holding is released by the action of the alternate mechanism, and when the pushing force is released, the tip end portion of the lever 352 protrudes from the outer casing 353, and the holding piece 351 is released. Thereby, the claw portion 223 is detached from the lock device 350.

A tank position detecting unit 360 is provided at a position on the left side of the lower portion of the outer casing 310. As shown in FIGS. 11( a ) and ( b ), the tank position detecting unit 360 is located below the tank receiving member 340 and includes a micro switch 361 and a switch holding unit 362 . The micro switch 361 detects whether the water supply tank 400 is in the insertion position, that is, whether or not the washing water is supplied from the water supply tank 400. The micro switch 361 corresponds to the detecting portion of the present invention. The micro switch 361 includes a switch portion 363 and an operating lever 364 for operating the switch portion 363. The switch holding portion 362 holds the micro switch 361 and is attached to the first body member 311 of the exterior body 310. The water tank receiving member 340 is provided with an operation block 345 that extends to the side of the micro switch 361. An opening portion 345a is provided in the operation block 345.

As shown in (a) of FIG. 11, when the water supply tank 400 is in the separated position and the tank receiving member 340 is in the ascending state, in the micro switch 361, the operating lever 364 is pushed toward the switch portion 363 by the lower end portion of the operating block 345, The switch portion 363 is pressed by the operating lever 364. Thereby, an on signal is output from the micro switch 361. The operating lever 364 generates an elastic force in a direction away from the switch portion 363. As shown in (b) of FIG. 11, when the water supply tank 400 is moved to the insertion position and the water tank receiving member 340 is pushed down, in the micro switch 361, the operating lever 364 is separated from the switch portion 363 and retracted to the opening of the operation block 345. In the portion 345a, the switch portion 363 returns to the original position. Thereby, the off signal is output from the micro switch 361.

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

A control unit 600 is disposed at a lower portion of the main body portion 300. The control unit 600 includes a microcomputer or the like and controls the ultrasonic generating body 110. The control unit 600 receives an ON signal and an OFF signal output from the micro switch 361. Further, the control unit 600 receives an operation signal corresponding to the operation of the operation button 372.

Next, the operation of the ultrasonic cleaning device 1 will be described.

When the washing operation is not performed, as shown in FIG. 6, in the water tank accommodating chamber 318, the water supply tank 400 is pushed up by the tank receiving member 340 to be held at the separated position. At this time, the valve body 441 of the water supply tank 400 is in a closed state, and the washing water is not discharged from the water supply tank 400. Further, the top surface of the water supply tank 400 protrudes upward from the top surface of the main body portion 300, and the top cover 420 of the water supply tank 400 is exposed to the outside. In this state, the user can grasp the grip portion 421 with a finger and take out the water supply tank 400 to the outside.

When the washing operation is performed, if there is no washing water in the water supply tank 400, the user takes the water supply tank 400 to the outside and turns it upside down, and opens the lid 430. After the user adds water to the position of the first engraving line 414 in the water supply tank 400, the liquid detergent is placed in the position of the second engraving line 415. After the lid 430 is closed, the water supply tank 400 is gently shaken to mix the liquid detergent with water. Thereby, washing water is generated in the water supply tank 400. After that, the user puts the water supply tank 400 into the main body portion 300 again.

The user presses the top cover 420 with the finger, that is, the top surface of the water supply tank 400, and presses the water supply tank 400 downward. The water supply tank 400 and the tank receiving member 340 are lowered against the elastic force of the coil spring 344, and the water supply tank 400 reaches the insertion position. As shown in FIG. 7, the discharge port portion 433 enters the groove accommodating chamber 316 through the central opening portion 317a together with the receiving portion 341, and the discharge port 401 of the water supply tank 400 is inserted into the water supply tank 250. Further, the first fitting projection 342 and the second fitting projection 343 enter the groove accommodating chamber 316 through the left opening 317b and the right opening 317c, respectively, and are embedded in the first fitting recess 221 and the second fitting recess 222. Hehe. Accordingly, the water storage unit 200 cannot be pulled out to the front, and the water storage unit 200 cannot be detached from the main body unit 300, which is the attachment base 320. On the other hand, between the first fitting protrusion 342 and the first fitting recess 221, the locking device 350 functions as a lock. In other words, the claw portion 223 of the water storage portion 200 is pushed into the outer casing 353 while being held by the holding piece 351, and is not detached from the lock device 350. Thereby, the elastic force of the coil spring 344 does not lift the tank receiving member 340, and therefore, the water supply tank 400 remains in the insertion position.

When the water supply tank 400 is lowered to the insertion position, the pin 442 of the water supply tank 400 touches the protrusion 252 of the water supply tank 250, and the pressing force against the coil spring 443 is pushed up. Thereby, the valve body 441 is separated from the outflow port 431, and the outflow port 431 is opened, and the washing water in the water supply tank 400 is discharged from the discharge port 401. The discharged washing water is taken up by the water supply tank 250 and sent to the water storage tank 240 through the water supply path 253. After the washing water is stored in the water storage tank 240, the water level in the water supply tank 250 rises together with the water level in the water storage tank 240. As shown by the alternate long and short dash line in FIG. 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 washing water, the air pressure and the external air pressure in the water supply tank 400 are passed. The balance is maintained, and the valve body 441 is kept open, and the water supply from the water supply tank 400 is stopped. In addition, even if water is generated during water supply and the washing water is splashed outside the water supply tank 250, the splashed washing water is recovered by the outer tank 260, so that the washing water does not easily leak out of the water storage unit 200.

When the washing water is stored in the water storage tank 240, the user places the dirt adhering portion of the object to be cleaned, for example, the collar portion of the shirt, on the water storage tank 240, that is, between the water storage tank 240 and the vibration horn 112 of the ultrasonic wave generating body 110. . The object to be cleaned is immersed in the washing water stored in the water storage tank 240, and the washing water that has penetrated into the inside of the object to be cleaned oozes out of the surface. A thin water layer is formed on the surface of the object to be cleaned, and the vibration horn 112 is in contact with the water layer. It should be noted that when the water level in the water storage tank 240 is lowered due to water absorption of the object to be washed and the water level in the water supply tank 250 is lowered, and the discharge port 401 of the water supply tank 400 is not blocked by the washing water, the water supply tank 400 is supplied from the water supply tank 400. The water tank 250, that is, the water storage tank 240, supplies the washing water until the discharge port 401 is again blocked by the washing water. Thereby, the water level in the water storage tank 240, that is, the amount of water, is maintained in an appropriate state.

In order to start the washing operation, the user presses the operation button 372.

When the water supply tank 400 is in the insertion position and is in the state in which the washing water is supplied from the water supply tank 400, the state is detected by the micro switch 361, and the disconnection signal is output from the micro switch 361 to the control unit 600. In this case, the control unit 600 energizes the ultrasonic vibrator 111 to operate the ultrasonic generating body 110. Thereby, the washing operation is started.

It should be noted that, in a case where the water supply tank 400 is not located at the insertion position, that is, at the separation position, and is not in the state of supplying the washing water from the water supply tank 400, the state is detected by the micro switch 361, and is controlled from the micro switch 361. The unit 600 outputs an on signal. In this case, the control unit 600 does not energize the ultrasonic vibrator 111, and does not operate the ultrasonic generating body 110. Thereby, the washing operation is not started in a state where the washing water is not supplied to the water storage tank 240.

(a) to (c) of FIG. 12 are views for explaining decontamination of the object to be cleaned by the ultrasonic cleaning device 1.

When the ultrasonic generating body 110 operates, ultrasonic waves are generated from the tip end of the vibration horn 112, and the ultrasonic vibration is transmitted to the washing water inside the object to be cleaned via the washing water around the vibration horn 112. As shown in FIG. 12(a), in the inside of the object to be cleaned, a pressure-reduced and pressurized pressure is alternately generated by the action of the ultrasonic vibration, and a cavity in which a vacuum is generated in a portion where the pressure is lowered is generated. That is, there are many states in which a large number of cavities exist in the contaminated portion of the object to be cleaned. Next, as shown in (b) of Fig. 12, when the pressure of the cavity portion becomes high and the cavity is broken by the pressure and is broken, a shock wave is generated to the contaminated portion of the object to be cleaned. The dirt is separated from the object to be cleaned by the shock wave. As shown in (c) of FIG. 12, the ultrasonic vibration from the vibration horn 112 generates a flow of water from the inside of the object to be washed toward the water storage tank 240, and the dirt separated from the object to be washed is discharged to the water storage tank through the water flow. Within 240. In the water storage tank 240, convection is generated by the above-described water flow, and therefore, it is easy to peel the dirt from the object to be cleaned. Further, by the action of the detergent contained in the washing water, the dirt is easily peeled off from the object to be cleaned, and the dirt is less likely to adhere to the object to be cleaned. In this way, dirt is removed from the object to be cleaned.

In order to place the contaminated portion of the object to be cleaned at the position of the ultrasonic generating body 110, the user mainly moves the object to be washed in the left and right direction. In the ultrasonic cleaning device 1 of the present embodiment, since the ultrasonic cleaning unit 100 is held by the main body unit 300, the user can hold the ultrasonic cleaning unit 100 without using the hand, and can hold the object to be cleaned with both hands. Thereby, the user can smoothly move the object to be cleaned as compared with the case of holding with one hand. Further, since the water storage unit 200 is attached to the main body unit 300, when the user moves the object to be cleaned, the water storage unit 200 does not easily move together with the object to be cleaned. Further, since the left and right side surfaces of the water storage tank 240 are the inclined surfaces 242, the object to be washed moves along the two inclined surfaces 242 and the bottom surface 241, so that the user can smoothly move the object to be cleaned. In particular, since the inclined surface 242 is a curved surface that is inclined toward the bottom surface 241, the object to be cleaned can be moved more smoothly.

When the cleaning of the object to be cleaned is completed, the user presses the operation button 372 again. The operation of the ultrasonic generating body 110 is stopped by the control unit 600, and the washing operation is ended. Thereafter, the user gently presses the water supply tank 400 downward with a finger. The water tank receiving member 340 is slightly lowered together with the water supply tank 400, and the first fitting protrusion portion 342 is slightly lowered. As a result, when the finger leaves the water supply tank 400, the claw portion 223 is released from the holding of the holding piece 351 in the locking device 350 to be disengaged from the locking device 350. Thereby, the fixing by the lock device 350 is released. Therefore, the water tank receiving member 340 rises by the elastic force of the coil spring 344, and is lifted by the water tank receiving member 340 to move the water supply tank 400 to the separated position. The pin 442 moves downward, and the outflow port 431 is closed by the valve body 441, and is in a state in which water cannot be supplied from the water supply tank 400.

In the cleaning operation, when the operation of pressurizing the water supply tank 400 as described above is performed, and the water supply tank 400 is moved to the separated position by the push-up of the tank receiving member 340, the ON signal is output from the micro switch 361. . Since the water supply regarded as the water supply tank 400 cannot be normally performed, the washing operation is automatically stopped by the control unit 600. Here, when the water supply tank 400 is in the insertion position, as shown in FIG. 7, the top surface of the water supply tank 400 and the top surface of the main body portion 300 are on one plane, and do not protrude upward from the top surface of the main body portion 300. Thereby, the user cannot grasp the water supply tank 400 with a finger, and the operation of pulling up the water supply tank 400 cannot be performed. Thereby, when the water tank receiving member 340 is in the lowered state, the micro switch 361 detects that the water supply tank 400 is in the inserted position, and it is unlikely that the water supply tank 400 is lifted and removed. Therefore, it is not easy to continue the cleaning operation in a state where the water supply from the water supply tank 400 cannot be performed.

When the water tank receiving member 340 ascends together with the water supply tank 400, the first fitting protrusion portion 342 and the second fitting protrusion portion 343 are detached from the first fitting recess portion 221 and the second fitting recess portion 222. Thereby, the water storage unit 200 can be detached from the main body unit 300, which is the attachment base 320.

When the washing operation ends, the user presses the operation button 281. As shown by the broken line in Fig. 8, when the operation button 281 is pressed, the valve body 283 moves downward together with the operation pin 282, and the valve body 283 is separated from the drain port 271 to open the drain port 271. The washing water stored in the water storage tank 240 and the water supply tank 250 is discharged through the water discharge port 271. The water discharged from the drain port 271 flows into the drain container 500 from the opening 521 and is stored in the drain container 500. When the washing water is completely discharged from the water storage tank 240 and the water supply tank 250, the user releases the operation button 281. The valve body 283 moves upward together with the operation pin 282 by the elastic force of the coil spring 284, and the valve body 283 closes the drain port 271.

The user grasps the handle portion 511 to pull the drain container 500 toward the front side, that is, the front side, and removes the drain container 500 from the water storage unit 200 as shown in FIG. When the drain container 500 is pulled out to the front, a force in the front direction, that is, the front side, is also applied to the water storage unit 200. However, the water storage unit 200 is prevented from moving forward by the blocking mechanism M. Thereby, it is possible to prevent the user of the water storage unit 200 from being detached from the main body unit 300 when the user wants to remove the drain container 500. The user takes the drain container 500 that has been removed to a place where it can be discarded, such as a washbasin, and discards the washing water stored in the drain container 500.

In addition, the drain container 500 is configured such that the lid 520 is fitted into the inside of the container body 510 from above, and the user can perform the operation of gripping the opening portion 521 with a finger, and the cover 520 is detached from the container body 510 upward. Thereby, the user can clean the inside of the container body 510 with the cover 520 removed.

Further, when the user cleans the water storage unit 200, that is, the water storage tank 240 and the water supply tank 250, as shown in FIG. 2, the water storage unit 200 is detached from the main body unit 300. At this time, first, as a release operation, the user slightly raises the front side of the water storage unit 200. The water storage unit 200 slightly rotates around the shaft portion 213. Thereby, in the blocking mechanism M, the engagement of the claw portion 233 of the hook portion 232 with the rib 323 is released. The user moves the water storage portion 200 obliquely forward until the claw portion 233 is positioned in front of the rib 323, and thereafter, the water storage portion 200 is restored to the original posture and continues to move. Thus, the water storage unit 200 is detached from the main body unit 300. The user performs an operation such as taking the water storage unit 200 that has been removed to the restroom, and cleaning the water storage tank 240 and the water supply tank 250. Further, the user can also directly remove the water storage unit 200 by leaving the washing water in the water storage tank 240 and the water supply tank 250, and at the same time, the washing water is discarded and the water storage unit 200 is cleaned.

Here, a case may be assumed in which the user erroneously starts the washing operation in a state where the water storage portion 200 is detached, and the water supply tank 400 is pushed into the insertion position. In this case, even if the water tank receiving member 340 is pushed down together with the water supply tank 400, since the claw portion 223 provided in the water storage portion 200 does not exist in the groove accommodation chamber 316, the claw portion 223 is not locked. The device 350 is held so that the locking function of the locking device 350 cannot be achieved. Therefore, the water supply tank 400 cannot be left in the insertion position and will return to the separation position.

As described above, according to the present embodiment, since the ultrasonic cleaning unit 100 is held by the main body unit 300, 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 unit 200 is attached to the main body unit 300, when the object to be cleaned is moved, the water storage unit 200 does not easily move together with the object to be cleaned, and water is less likely to be scattered from the water storage unit 200. Further, the water discharged from the water storage tank 240 or the like can be stored in the drain container 500, and the drain container 500 can be separated from the water storage unit 200 and the main body unit 300. Therefore, it is easy to discard the used washing water.

As described above, according to the present embodiment, the user can perform the smooth cleaning of the object to be cleaned using the ultrasonic cleaning device 1, and the user's convenience can be expected to be improved.

Further, according to the present embodiment, the user can easily discharge the washing water from the water storage tank 240 or the like to the drain container 500 simply by pressing the operation button 281.

Further, according to the present embodiment, since the drain container 500 is provided in the water storage unit 200, the drain path from the water storage tank 240 and the like to the drain container 500 can be shortened, and the drain container 500 can be smoothly drained.

Further, according to the present embodiment, the water storage unit 200 can be detached from the main body unit 300. Thereby, the water storage tank 240 and the like can be easily cleaned. Further, the washing water remaining in the water storage tank 240 or the like can be directly discarded without being discharged to the drain container 500.

Further, according to the present embodiment, since the drain container 500 and the water storage unit 200 are in the same direction of separation, the user can easily handle the drain container 500 and the water storage unit 200. Further, since the water storage unit 200 can be moved in the disengaging direction by the movement of the drain container 500 in the disengaging direction by the blocking mechanism M, it is possible to prevent the water storage unit 200 from the user to discharge the drain container 500 from the water storage unit. When the 200 is removed, it is detached from the main body portion 300.

Further, according to the present embodiment, when the washing water is not supplied from the water supply tank 400, the ultrasonic generating body 110 does not operate, and the washing operation is not performed. Therefore, it is possible to prevent the cleaning operation from being performed unnecessarily.

Further, according to the present embodiment, since the water storage tank 240 has the inclined surface 242 on the left and right sides of the bottom surface 241, the user can smoothly move the contaminated portion of the object to be cleaned toward the distal end position of the ultrasonic wave generating body 110. The object to be cleaned moves in the left and right direction. Thereby, the user can easily clean the object to be cleaned.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made in addition to the above.

FIG. 13 is a perspective view of the water storage unit 200 in a state in which the front water storage member 210 and the rear water storage member 220 are removed and the drain container 500 is attached. (a) of FIG. 14 is a front cross-sectional view of the water storage unit 200 at a position where the operation button 281 is removed from the accommodating member 230, and FIG. 14(b) is a rear upper portion of the water storage unit 200 of the modified example. Side section view.

In the present modification, the ultrasonic cleaning device 1 includes the blocking mechanism 700 in the water storage unit 200. When the washing water is supplied from the water supply tank 400, the blocking mechanism 700 prevents the operation button 281 from being pressed, thereby preventing the valve body 283 from leaving the drain port 271 and opening the drain port 271.

It should be noted that in the present modification, the operation pin 282 is formed separately from the operation button 281 and is attached to the back side of the operation button 281.

The blocking mechanism 700 includes a button stopper 710, a sliding rod 720, a rod supporting member 730, and two coil springs 740. The button stopper 710 is disposed below the operation button 281. In the button stopper 710, a stopper pin 711 extending toward the back side of the operation button 281 and a shaft portion 712 extending laterally from the root of the stopper pin 711 are provided on the right and left sides. Each of the stopper pins 711 is inserted into a guide hole 214 provided in the front water storage member 210. Thereby, the button stopper 710 can only move in the up and down direction.

The slide bar 720 has a cam hole 721 on the right and left sides of the front end portion, and has an arm portion 722 that is split toward the left and right sides and extends rearward at the rear portion. The cam hole 721 is provided as an elongated hole that extends obliquely upward toward the rear direction, and the front end is open. The shaft portion 712 of the button stopper 710 is inserted into the cam hole 721. Further, in the slide bar 720, an elliptical front sliding hole 723 is formed in a central portion of the front portion.

At the rear of the arm portion 722, an elliptical rear sliding hole 724 is formed. The projection 215 provided on the back side of the front water storage member 210 is inserted into the rear sliding hole 724 (refer to (b) of FIG. 14). Further, at the rear end of the arm portion 722, an inclined surface 725 that is inclined downward toward the rear is formed.

The lever support member 730 supports the slide lever 720 so that the slide lever 720 can move from the lower direction to the front-back direction. The rod support member 730 is fixed to the back side of the front water storage member 210. In the rod supporting member 730, a cylindrical projection 731 into which the front sliding hole 723 is inserted is formed. The slide bar 720 can be guided in the forward and backward directions by the

projections

731, 215 inserted into the front slide hole 723 and the rear slide hole 724.

The coil spring 740 is disposed between the front water storage member 210 and the arm portion 722. The slide lever 720 is pushed rearward by the elastic force of the coil spring 740, and the rear end of the left and right arm portions 722 are exposed to the first fitting recess 221 of the rear water storage member 220 and the second recessed state in a state of being pushed rearward. The inside of the recessed portion 222 is closed (see (b) of Fig. 14).

(a) and (b) of FIG. 15 are diagrams for explaining an operation of the blocking mechanism 700 in a modified example.

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

As shown in (b) of FIG. 15, when the water supply tank 400 is moved to the insertion position, so that the tank receiving member 340 is pushed down, the tank receiving member 340 is inserted through the first fitting recess 221 and the second fitting recess 222. The first fitting protrusion 342 and the second fitting protrusion 343 push the inclined surface 725 of the rear end of the left and right arm portions 722, and the slide bar 720 moves to the front position against the elastic force of the coil spring 740. The shaft portion 712 of the button stopper 710 is guided to the rear end portion of the cam hole 721 to move to the upper position. In this state, the stopper pin 711 is located in the vicinity of the back surface of the operation button 281. Thereby, since the stopper pin 711 is in contact with, the operation button 281 cannot be pressed downward, and it is not possible to drain from the water storage tank 240 or the like.

As described above, in the present modification, when the water supply tank 400 is in the insertion position and the washing water is supplied from the water supply tank 400 to the water storage tank 240, the apparatus can be prevented from draining from the water storage tank 240, and therefore, the operation can be prevented. The erroneous operation of the button 281 causes drainage from the water storage tank 240, and wastes the washing water in the water supply tank 400.

In the above embodiment, the water stored in the water supply tank 400 and supplied to the water storage tank 240 is water containing detergent, but may be water containing no detergent. In this case, it is possible to apply a detergent to the contaminated portion of the object to be cleaned before the cleaning operation.

Further, in the above embodiment, the water storage unit 200 is detachably attached to the main body unit 300. However, the water storage unit 200 may not be separated from the main body unit 300. For example, the water storage unit 200 may be configured to be integrated with the attachment base 320 and integrated with the main body portion 300.

Further, in the above embodiment, the drain container 500 is detachably provided in the water storage unit 200. However, the drain container 500 may be detachably provided to the main body portion 300. For example, the drain container 500 may be detachably attached to the front surface of the attachment station 320.

Further, in the above embodiment, the outer casing 130 of the ultrasonic cleaning unit 100 is disposed independently of the member of the main body portion 300. However, the outer casing 130 may be integrally formed with the main body portion 300.

Further, in the above-described embodiment, the blocking mechanism M is configured to release the engagement between the claw portion 233 of the hook portion 232 and the rib 323 by the operation of tilting the water storage portion 200. However, the structure of the blocking mechanism M is not limited to the above-described configuration. For example, a structure in which the hook portion 232 is movable may be employed, and the hook portion 232 is moved by an operation from the outside, thereby releasing the claw portion 233 and the rib. 323 engagement.

Further, in the above-described embodiment, the drain mechanism 280 is configured such that the operation pin 282 moves downward as the operation button 281 is pressed, and the valve body 283 is separated from the drain port 271 to open the drain port 271. However, the structure for opening and closing the drain port 271 is not limited to the above structure. For example, a configuration may be adopted in which an openable and closable electromagnetic valve is provided in the drain port 271, an input circuit receives an operation of the operation button 281, and the control unit 600 opens and closes the solenoid valve based on an operation signal from the input circuit.

Further, in the above embodiment, the micro switch 361 indirectly detects that the water supply tank 400 is at the insertion position via the tank receiving member 340 by contact with the operation block 345 of the tank receiving member 340. However, it is also possible to adopt a configuration in which the water supply tank 400 is partially in contact with the micro switch 361, so that the water supply tank 400 is directly detected by the micro switch 361 at the insertion position.

Further, the water supply structure for supplying water from the water supply tank 400 to the water storage tank 240 is not limited to the configuration as in the above embodiment, and another water supply structure may be employed. Further, it is also possible to adopt a configuration in which the water supply tank 400 is not provided in the ultrasonic cleaning device 1, and water is directly supplied to the water storage tank 240 from a container or a faucet prepared by the user.

Further, the embodiments of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
