Summary of the Invention

Problems to be Solved by the Invention

[0004] The cleaning device as described in Patent Document 1 can remove dirt adhering to an object to be cleaned with a cleaning liquid mixed with gas, but it cannot adjust the strength of the swirling water flow according to the object to be cleaned. Therefore, whether washing root vegetables or leafy vegetables, the strength of the water flow had to be the same.

[0005] Therefore, an object of the present invention is to provide a cleaning device capable of adjusting the strength of the water flow of the cleaning liquid in the tank.

Means for Solving the Problems

[0006] A cleaning device (10) according to one solution of the present invention circulates the cleaning liquid in the cleaning tank using a pump. The cleaning device (10) has a plate (20) that divides the cleaning tank (11) into a first area (12) and a second area (13), and a first nozzle (40, 41) and a second nozzle (43) for discharging the cleaning liquid, characterized in that the first nozzle (40, 41) discharges the cleaning liquid into the first area (12) and the second nozzle (43) discharges the cleaning liquid into the second area (13). [Effects of the Invention]

[0009] In the embodiments of the present invention described below, explanations will be divided into multiple sections where necessary. However, in principle, these sections are not unrelated to each other; one may be a modification or detail of part or all of the other. For this reason, in all figures, components having the same function are denoted by the same reference numeral, and repeated explanations will be omitted.

[0010] Furthermore, the number of constituent elements (including the number of items, numerical values, quantities, ranges, etc.) is not limited to a specific number unless otherwise explicitly stated or unless it is clearly limited in principle; it may be greater than or less than that specific number. Also, when referring to the shape of constituent elements, unless otherwise explicitly stated or unless it is clearly not the case in principle, it should include those that are substantially similar or approximate to that shape.

[0011] Embodiments of the present invention will be described with reference to the drawings. Figure 1 is a front view of a cleaning device according to one embodiment of the present invention, Figure 2 is a plan view of the cleaning device, Figure 3 is a cross-sectional view taken along line A-A in Figure 1, Figure 4 is a cross-sectional view taken along line BB in Figure 1, and Figure 5 is a cross-sectional view taken along line CC in Figure 2.

[0012] The washing device 10 is a device for washing products and materials produced in agriculture or fisheries, for example. The washing device 10 is equipped with a washing tank 11. The washing tank 11 is divided into a first area 12 and a second area 13 by a plate 20. Since the plate 20 has slits 21 arranged in a grid pattern, washing water can move back and forth between the first area 12 and the second area 13. The plate 20 is also equipped with nozzle holes 22. The nozzle holes 22 are holes for passing the washing liquid discharged from the nozzles 40 and 41 (first nozzles) of the circulation device 30, which will be described later.

[0013] The first area 12 is for washing items to be washed, such as products and materials produced in agriculture and fisheries, while the second area 13 is for filtering out foreign matter mixed into the washing solution. The second area 13 is also equipped with a circulation device 30 that generates convection in the washing tank 11. Therefore, the second area 13 is also the source of convection in the washing tank 11.

[0014] The floor (bottom) of the washing tank 11 is equipped with a bottom plate 14. The bottom plate 14 has perforated holes. Heavy foreign matter such as mud adhering to the object to be washed passes through the holes and sinks to the floor of the washing tank 11. The washing tank 11 is equipped with drain ports 15, 16, and 17. Drain ports 15 and 16 are located on the wall near the bottom of the washing tank 11 and drain the washing solution after washing. Drain port 17 is located on the bottom of the washing tank 11 (shown in Figure 5) and drains the washing solution after washing. Because drain port 17 is located on the bottom, it makes it easy for the user to collect the mud that has settled on the bottom after draining and discharge it through drain port 17. A tray 18 for receiving mud is provided below drain port 17. After draining the washing solution, the user inserts tray 18 into the tray insertion port and collects the mud that has settled on the floor and discharges it through drain port 17. The discharged mud is received by tray 18. The user can pull out tray 18 and discard the mud.

[0015] The cleaning device 10 may be configured to have a sloped floor surface in the cleaning tank 11. If the floor surface is sloped, for example toward the drain outlet 17, foreign matter such as mud that settles on the floor surface will accumulate in one place. This makes it easier to discharge the settled foreign matter such as mud. Alternatively, one side of the cleaning device 10 may be lifted with something like a jack. By lifting it, the floor surface of the cleaning device 10 will be sloped, causing foreign matter such as mud that settles on the floor surface to accumulate in one place and be easier to scrape up.

[0016] The cleaning device 10 is equipped with a filtration unit 23 in the second area 13. The filtration unit 23 is located downstream of the plate 20 to filter the cleaning liquid passing through the slits 21 of the plate 20. The filtration unit 23 has a hollow rectangular shape, with an open surface that contacts the slits 21 of the plate 20. The filtration unit 23 has, for example, perforated holes. Therefore, the cleaning liquid circulating in the cleaning tank 11 passes through the slits 21 of the plate 20 and then through the filtration unit 23, thereby removing foreign matter.

[0017] The cleaning device 10 includes a guiding path 19 for allowing the cleaning liquid discharged from the ejection port 43 to pass through. The guiding path 19 has a box shape with an open bottom. The cleaning liquid discharged from the ejection port 43 flows into the guiding path 19 and flows out from the open bottom. The guiding path 19 has a certain length so as to discharge the cleaning liquid discharged from the ejection port 43 into the liquid (in water). By discharging the cleaning liquid discharged from the ejection pipe 43 into the water, it prevents the cleaning liquid from splashing. Also, the guiding path 19 is provided at a distance from the plate 20. When the cleaning liquid discharged from the ejection port 43 flows into the guiding path 19, the guiding path 19 vibrates due to the discharging momentum. Therefore, by separating the guiding path 19 from the plate 20, contact with the plate 20 is prevented.

[0018] As described above, the plate 20 is provided with a lattice-shaped slit 21. The width of the slit 21 (one hole) may be changed according to the size of the object to be cleaned. The plate 20 is provided with nozzle holes 22 for allowing the cleaning liquid discharged from nozzles 40 and 41 described later to pass through. The nozzle holes 22 are provided close to the discharge ports 47 of the nozzles 40 and 41 and maintain a predetermined distance so as not to contact the nozzle holes 22 even when the nozzles 40 and 41 vibrate when discharging the cleaning liquid. Also, even if there is a gap between the discharge ports 47 of the nozzles 40 and 41 and the nozzle holes 22, the cleaning liquid stored in the first area 12 is difficult to flow into (backflow) the nozzle holes 22 due to the momentum of the cleaning liquid ejected from the nozzles 40 and 41.

[0019] The cleaning device 10 includes a circulation device 30 for circulating the cleaning liquid. The circulation device 30 includes a pump P, nozzles 40 and 41 (first nozzles), an ejection port 43 (second nozzle), a pipe 24, and the like. The circulation device 30 sucks the cleaning liquid with the pump P and discharges the cleaning liquid from the nozzles 40 and 41 and the ejection port 43 through the pipe 24, thereby circulating the cleaning liquid in the cleaning tank 11. Specifically, when the cleaning liquid passing through the slit 21 of the plate 20 flows into the filtering unit 23, the cleaning liquid is filtered and foreign substances are removed. The cleaning liquid from which foreign substances have been removed is supplied to the pump P. The supplied cleaning liquid flows from the pump P to the pipe 24.

[0020] FIG. 6 is a schematic diagram of the nozzles 40 and 41 shown in FIG. 4, and FIG. 7 is a cross-sectional view of the nozzles 40 and 41 shown in FIG. 4. The circulation device 30 includes the nozzles 40 and 41. The nozzle 40 includes a fluid drive port 45 connected to a branch pipe 25 (the nozzle 41 is connected to a branch pipe 26 to be described later), a discharge port 47 for ejecting a cleaning liquid, and a converging portion 48 between the fluid drive port 45 and the discharge port 47. In the nozzles 40 and 41, the fluid drive port 45 and the converging portion 48 are provided at a distance from each other. Therefore, the nozzles 40 and 41 are provided with a bridge 49 connecting the fluid drive port 45 and the converging portion 48. The space between the fluid drive port 45 and the converging portion 48 is referred to as a fluid inlet 46. The fluid inlet 46 can take in the cleaning liquid around the nozzles 40 and 41. Further, the nozzles 40 and 41 include a duct 51. The duct 51 communicates with the converging portion 48. One end of the duct 51 communicates with the converging portion 48, and the other end extends to above the liquid surface. Therefore, the duct 51 can take in gas.

[0021] The flow of the fluid in the nozzles 40 and 41 will be described. When the cleaning liquid flows into the fluid drive port 45 connected to the pipe 24, the cleaning liquid flows toward the flow generation portion 50. The flow generation portion 50 has a smaller diameter than the fluid drive port 45. Therefore, the cleaning liquid flowing toward the flow generation portion 50 increases in flow velocity due to the Venturi effect caused by restricting the flow of the fluid. Then, since the pressure around the flow generation portion 50 becomes low, the cleaning liquid around the nozzles 40 and 41 flows in from the open fluid inlet 46. The inflowing cleaning liquid is mixed with the cleaning liquid flowing out from the flow generation portion 50.

[0022] The nozzles 40 and 41 are narrowed by the converging portion 48 in the middle from the fluid drive port 45 to the discharge port 47. Therefore, the flow velocity of the cleaning liquid increases again. The cleaning liquid that has passed through the converging portion 48 is ejected from the discharge port 47. The nozzles 40 and 41 can eject a cleaning liquid amount exceeding the discharge capacity of the pump P.

[0023] Furthermore, nozzles 40 and 41 are equipped with ducts 51. As the cleaning fluid passes through the converging section 48, its flow velocity increases due to the narrowing of the pipeline. This lowers the pressure around the duct 51, causing gas to be drawn in from the duct 51 into the converging section 48. The drawn-in gas mixes with the cleaning fluid passing through the converging section 48, resulting in a cleaning fluid containing air bubbles. More specifically, when the cleaning fluid flows through the converging section 48 where the pipeline narrows, the flow velocity of the cleaning fluid increases due to the Venturi effect. This reduces the pressure around the converging section 48. At this time, the pressure inside the converging section 48 is lower than the pressure at the other end of the duct 51 (atmospheric pressure), so air is drawn into the converging section 48 through the duct 51. This supplies air from the duct 51 into the interior of the converging section 48. At this time, cavitation is more likely to occur, and a cleaning fluid in which liquid and gas are mixed is generated.

[0024] Because the cleaning solution contains air bubbles, it can clean objects even if they have foreign matter such as leaves, wood chips, or insects attached to them. For example, the air-bubble-containing cleaning solution collides with the object being cleaned, which may have mud attached to it, as it is discharged from nozzles 40 and 41. The impact of the collision allows the cleaning solution to detach the dirt attached to the object being cleaned. Because the discharged cleaning solution contains air bubbles, it can clean the object being cleaned gently. It is also less likely to damage the object being cleaned.

[0025] In this embodiment, the system has been described as taking in gas from the duct 51, but it is not limited to this configuration. For example, it may also be configured to take in a liquid such as disinfectant solution to clean or disinfect the object to be cleaned. Furthermore, the number of ducts 51 for nozzles 40 and 41 may be changed depending on the size (capacity) of the nozzles 40 and 41.

[0026] Figure 8 is an explanatory diagram of the water flow adjustment device 60. The cleaning device 10 is equipped with a water flow adjustment device 60 that adjusts the strength of the water flow of the cleaning solution. The water flow adjustment device 60 is provided in the circulation device 30. The water flow adjustment device 60 comprises a pipe 24, branch pipes 25, 26, and 27, nozzles 40 and 41, a control valve 61, a nozzle 43, and a lever 62 as shown in Figure 5. The pipe 24 connected to the pump P branches into branch pipes 25, 26, and 27. Branch pipe 25 is connected to nozzle 40, branch pipe 26 is connected to nozzle 41, and branch pipe 27 is connected to nozzle 43 via control valve 61.

[0027] The control valve 61 is connected to the lever 62. The lever 62 adjusts the amount of cleaning fluid flowing through the branch pipe 27 by adjusting the opening and closing of the control valve 61. The control valve 61 is preferably a ball valve or a solenoid valve. When the lever 62 is displaced (rotated) in one direction, the branch pipe 27 closes, and the flow of cleaning fluid through the branch pipe 27 stops. As a result, cleaning fluid is no longer discharged from the nozzle 43. The cleaning fluid passing through pipe 24 does not flow into the branch pipe 27, but instead flows into branch pipes 25 and 26. Therefore, the cleaning fluid is discharged from nozzles 40 and 41.

[0028] Furthermore, when lever 62 is displaced (rotated) to the other side, branch pipe 27 opens, and the cleaning fluid flows into branch pipe 27 and is discharged from nozzle 43. As a result, the cleaning fluid flowing through pipe 24 flows into branch pipes 25, 26, and 27 and is discharged from nozzles 40, 41 and nozzle 43.

[0029] As mentioned above, nozzles 40 and 41 are nozzles that utilize the Venturi effect. The nozzle outlet 43, on the other hand, is a nozzle that does not have the function of the Venturi effect. As mentioned above, the flow velocity of the cleaning liquid discharged from nozzle 40 (or nozzle 41) is increased by the flow generation section 50 and the converging section 48 (due to the Venturi effect). However, the flow velocity of the cleaning liquid discharged from nozzle outlet 43 does not change between inflow and outflow. Therefore, the flow velocity of the cleaning liquid discharged from nozzle 40 (and nozzle 41) is faster than that of the cleaning liquid discharged from nozzle outlet 43.

[0030] When lever 62 is displaced to one side, the water flow of the cleaning fluid in the cleaning tank 11 (the flow velocity of the cleaning fluid in the first area 12) becomes stronger compared to when lever 62 is displaced to the other side. This is because the cleaning fluid flowing through pipe 24 splits into branch pipes 25 and 26, and the cleaning fluid flowing through branch pipes 25 and 26 is discharged from nozzles 40 and 41. The discharged cleaning fluid flows through the nozzle holes 22 of plate 20 and into the first area 12. In addition, the cleaning fluid flowing through branch pipe 27 is not allowed to flow due to the control valve 61. Therefore, the entire amount of cleaning fluid passing through pipe 24 is discharged into the first area 12.

[0031] When lever 62 is moved to the other side (opening branch pipe 27), the cleaning fluid flowing through pipe 24 branches into three branch pipes 25-27. The cleaning fluid flowing through branch pipes 25 and 26 is discharged from nozzles 40 and 41 and flows into the first area 12. The cleaning fluid flowing into branch pipe 27 is discharged from nozzle 43. The plate 20 separating the first area 12 and the second area 13 does not have any holes for the cleaning fluid discharged from nozzle 43 to flow through. Therefore, the cleaning fluid discharged from nozzle 43 remains in the second area 13. The cleaning fluid remaining in the second area 13 is supplied to pump P.

[0032] When lever 62 is displaced in one direction (when the branch pipe 27 is closed), the amount of cleaning fluid discharged into the first area 12 is greater than when lever 62 is displaced in the other direction (when the branch pipe 27 is opened), so the water flow in the first area 12 becomes stronger. For example, when the object to be cleaned is something that would sink in water, strengthening the water flow in the first area 12 causes the object to circulate. As a result, the cleaning fluid penetrates into the uneven surfaces of the object, and any foreign matter trapped in these surfaces is washed away.

[0033] Furthermore, when the lever 62 is displaced to the other side (when the branch pipe 27 is opened), the amount of cleaning fluid discharged into the first area 12 is less than when the lever 62 is displaced to one side (when the branch pipe 27 is closed), so the water flow in the first area 12 becomes weaker. The objects to be cleaned in the first area 12 move slowly through convection, so they can be cleaned without colliding with each other.

[0034] Furthermore, the control valve 61 can adjust the amount of cleaning fluid flowing through the branch pipe 27. Therefore, when the lever 62 is moved from one side to the other (or vice versa), the amount of cleaning fluid flowing through the branch pipe 27 can be changed little by little. This makes it possible to gradually change the strength of the water flow of the cleaning fluid circulating in the first area 12.

[0035] The cleaning device 10 is equipped with an electrical unit 70. The electrical unit 70 includes a main power switch 71, a power lamp 74, an operation switch 72, a stop switch 73, a manual / automatic selector switch 75, a timer 76, a timer buzzer 77, and an indicator light 78. The main power switch 71 turns the power of the cleaning device 10 on and off. The power lamp 74 lights up when the power of the cleaning device 10 is on, indicating that the power of the cleaning device 10 is on. The operation switch 72 starts the drive of the pump P, and the stop switch 73 stops the drive of the pump P. The timer 76 sets the operating time of the cleaning device 10. The cleaning device 10 operates within the set time and stops after the set time has elapsed. The timer buzzer 77 notifies the user that the set time has elapsed when the time set by the timer 76 has elapsed. The indicator light 78 notifies the user that the set time has elapsed when the time set by the timer 76 has elapsed.

[0036] Next, the method of using the cleaning device 10 and the flow of the cleaning solution will be explained. First, the user presses the main power switch 71 to turn on the cleaning device 10. The user places the object to be cleaned into the first area 12 of the cleaning tank 11. In this embodiment, Jerusalem artichokes will be used as the object to be cleaned. The user selects the automatic mode with the manual / automatic switch 75 and presses the start button. Next, the user sets the timer 76 to 10 minutes. The user confirms that the cleaning device 10 is running and adjusts the strength of the water flow of the cleaning device 10 by moving the lever 62 according to the degree of soiling of the object to be cleaned. Because Jerusalem artichokes have many uneven surfaces, mud and other debris can get into the recesses. Also, since Jerusalem artichokes sink in water, the user moves the lever 62 to one side to adjust the water flow of the cleaning device 10 to be stronger.

[0037] The cleaning device 10 drives the pump P when the operation switch 72 is pressed, and the timer 76 measures the operating time. The cleaning fluid around the pump P in the second area 13 flows into the pump P. The cleaning fluid flows into the pipe 24 due to the water supply from the pump P. The cleaning fluid that flows into the pipe 24 branches off into branch pipes 25 and 26. Because the lever 62 was displaced to one side by the user, the cleaning fluid does not flow into branch pipe 27. The cleaning fluid that flows into branch pipes 25 and 26 is discharged from nozzles 40 and 41 and discharged into the first area 12.

[0038] The flow of the cleaning fluid through nozzles 40 and 41 is described below. The cleaning fluid flowing into nozzles 40 and 41 proceeds from the fluid drive port 45 to the fluid inlet 46. Since the drive generation unit 50 has a narrower diameter than the fluid drive port 45, the flow velocity of the cleaning fluid increases. Also, the cleaning fluid around nozzles 40 and 41 is drawn into the fluid inlet 46 and merges with the cleaning fluid passing through the fluid generation unit 50. The merged cleaning fluid then proceeds to the convergence unit 48. Since the constriction of the converging unit 48 at nozzles 40 and 41 increases the flow velocity of the cleaning fluid. When the convergence unit 48 becomes negative pressure, air is drawn in from the duct 51. The drawn-in air merges with the cleaning fluid passing through the convergence unit 48. By merging with the air, the cleaning fluid becomes a gas-liquid mixture (a mixture of gas and liquid), which is then discharged from the discharge port 47. The cleaning fluid flowing through branch pipes 25 and 26 is discharged with increased flow velocity after passing through nozzles 40 and 41.

[0039] The cleaning fluid discharged from nozzles 40 and 41 passes through the nozzle holes 22 in plate 20 and flows into the first area 12. The cleaning fluid is discharged from nozzles 40 and 41 (nozzle holes 22). That is, it is discharged from the bottom of the cleaning tank 11. The discharged cleaning fluid bounces off the walls of the cleaning tank 11 and flows towards the slits 21 in plate 20. As a result, convection is generated in the cleaning tank 11, such as swirling from bottom to top as shown by the arrows in Figure 5, or swirling around nozzles 40 and 41 as shown by the arrows in Figure 2. Complex convection is generated in the cleaning tank 11 by nozzles 40 and 41.

[0040] At this time, the cleaning solution contains air bubbles, which allows it to clean away dirt such as mud adhering to the Jerusalem artichokes. For example, the cleaning solution discharged from nozzles 40 and 41 collides with the Jerusalem artichokes that have mud attached to them. Because the cleaning solution contains air bubbles, the impact of the collision can peel off the dirt adhering to the Jerusalem artichokes. Since the discharged cleaning solution contains air bubbles, it can gently clean the object being cleaned and is less likely to damage the object being cleaned.

[0041] By displacing lever 62 to one side, the water flow in the first area 12 is strong. This allows for convection of objects to be washed that sink in water, such as Jerusalem artichokes, and thus enables the washing away of foreign matter adhering to the Jerusalem artichokes.

[0042] The cleaning solution circulating in the first area 12 flows into the slit 21 of the plate 20. Since the cleaning solution contains foreign matter attached to the Jerusalem artichokes and other plants, larger foreign matter such as leaves is removed by the slit 21. The plate 20 is provided with nozzle holes 22 and slit 21, so the cleaning solution that passes through the nozzle holes 22 and flows into the first area 12 passes through the slit 21 and flows into the filtration section 23 of the second area 13. The filtration section 23 removes foreign matter attached to the Jerusalem artichokes from the cleaning solution. The cleaning solution from which the foreign matter has been removed is sucked into the pump P, passes through pipe 24 and branch pipes 25 and 26, and is discharged again from nozzles 40 and 41 and flows into the first area 12. In this way, the cleaning solution circulates in the cleaning tank 11. The cleaning device 10 cleans the items to be cleaned while circulating the cleaning solution, which also helps to conserve water.

[0043] When the washing device 10 has elapsed for the time set by the user (10 minutes), it sounds a timer buzzer 77 and lights up an indicator light 78 to notify the user, and also stops operating. The user then removes the washed Jerusalem artichokes.

[0044] In this embodiment, Jerusalem artichokes were used as an example, but when the object to be cleaned is something like bean sprouts, it is advisable to weaken the water flow of the cleaning device 10. The water flow can be weakened by the user turning lever 62 to the other side (opening the branch pipe 27). The adjustment valve 61 connected to lever 62 opens the branch pipe 27, and the cleaning liquid flows into the branch pipe 27 and is discharged from the nozzle 43. Plate 20 does not have any holes for the cleaning liquid discharged from the nozzle 43 to pass through. Therefore, the cleaning liquid discharged from the nozzle 43 remains in the second area. The remaining cleaning liquid is sucked into pump P. The cleaning liquid that flows again from pipe 24 to branch pipes 25-27 is partially discharged from nozzle 43 and partially discharged from nozzles 40 and 41. Therefore, the flow rate of cleaning liquid flowing into the first area 12 is less than when branch pipe 27 is closed. Thus, the water flow in the first area 12 is weakened. When dealing with fragile objects to be cleaned, such as bean sprouts, the cleaning device 10 can clean them without damaging their shape by slowly circulating the bean sprouts in the first area 12. Furthermore, even if the water flow in the first area 12 is weakened (by opening the branch pipe 27), the cleaning solution is still discharged from the nozzles 40 and 41, allowing for cleaning with a cleaning solution containing air bubbles.

[0045] The water flow adjustment device 60 branches the pipe 24 into three branch pipes 25, 26, and 27. By equipping branch pipe 27 with an adjustment valve 61, the amount of water flowing into the first area can be adjusted. By adjusting the amount of water, the strength of the water flow in the first area 12 can be adjusted.

[0046] The water flow adjustment device 60 branches pipe 24 into three branch pipes 25, 26, and 27. Cleaning fluid discharged from nozzles 40 and 41 via branch pipes 25 and 26 is discharged into the first area 12, and cleaning fluid discharged from outlet 43 via branch pipe 27 is discharged into the second area 13. Cleaning fluid is discharged from outlet 43 when lever 62 is moved to the other side. When lever 62 is moved to the other side (opening branch pipe 27), the water flow in the first area 12 weakens. If branch pipe 27 (outlet 43) were not provided, the water flow of the cleaning fluid in the second area 13 would also weaken. In other words, by providing branch pipe 27 (outlet 43) and discharging cleaning fluid into the second area 12, it is possible to maintain the strength of the water flow of the cleaning fluid in the second area 13 even if the water flow of the cleaning fluid in the first area is weakened. By maintaining the strength of the water flow of the cleaning solution in the second area 13, the cleaning solution in the second area 13 can be circulated evenly. Consequently, the cleaning solution in the cleaning device 10 can be circulated evenly.

[0047] The water flow adjustment device 60 branches pipe 24 into three branch pipes 25, 26, and 27, and has an adjustment valve 61 in branch pipe 27. In this way, even if branch pipe 27 is closed, branch pipes 25 and 26 remain open. Therefore, even if the adjustment valve 61 is displaced to one side (even if branch pipe 27 is closed), cleaning solution containing air bubbles continues to be discharged from nozzles 40 and 41 (branch pipes 25 and 26). The cleaning solution in the cleaning tank 11 can always be kept containing air bubbles, so dirt adhering to the object being cleaned can be removed.

[0048] The water flow adjustment device 60 branches the pipe 24 into three branch pipes 25, 26, and 27, and has an adjustment valve 61 in the branch pipe 27. This allows the strength of the water flow of the cleaning solution in the first area 12 to be adjusted by displacing the lever 62. At this time, because the adjustment valve is provided in the branch pipe 27, the cleaning solution continues to be ejected from the nozzles 40 and 41 even when the lever 62 is displacing (even when the branch pipe 27 is narrowed). In other words, the strength of the water flow can be adjusted while discharging cleaning solution containing air bubbles into the first area 12. This makes it possible to adjust the strength of the water flow according to the object being cleaned.
