The supply pump 112 operates, the air in the first water channel 113 is sucked to form a negative pressure, and the liquid detergent in the first medicine box 150 is sucked into the first water channel 113 through the first supply pipe 155 . The supply pump 112 operates for a predetermined time, and a predetermined amount of liquid detergent is stored in the first water passage portion 113 .

Next, the first three-way valve 115 is switched to a state in which the upstream side and the downstream side of the first three-way valve 115 in the first water passage portion 113 communicate, and the first water supply valve 114 is opened. The pure water from the faucet flows to the first water channel 113 to wash away the liquid detergent. Pure water and liquid detergent are mixed to become detergent water. The detergent water flows into the storage box 111 through the supply pump 112 .

When a predetermined amount of detergent water is stored in the storage box 111, the first water supply valve 114 is closed. In this way, the detergent water having a predetermined detergent concentration is stored in storage box 111 .

Next, the supply valve 117 is opened. The detergent water in the storage box 111 passes through the connecting pipe 118 , the first inlet 131 , and the cover portion 134 , and is released into the junction portion 130 from the opening 134 a. The detergent water flows to the water storage tank 40 through the connection part 140 and the water supply port 41 and is stored in the water storage tank 40 . As shown by the dash-dot line in Figure 1, when the water level in the water storage bucket 40 rises to the height of the opening 134a of the cover 134 and the opening 134a is blocked by detergent water, the air pressure in the storage box 111 is different from the air pressure outside. phase balance. As a result, the supply of water from the storage box 111 is stopped while the supply valve 117 is kept open. About one-third of the detergent water when the storage box 111 is full remains. The tip of the sonotrode 210 is in contact with the water surface.

When the detergent water is stored in the water storage tank 40 , the user places the dirt-attached part of the laundry between the water storage tank 40 and the vibration horn 212 of the ultrasonic generator 210 . The dirt-adhered portion of the laundry is soaked in the detergent water, and the detergent water permeated into the inside of the laundry seeps out to the surface. A thin water layer is formed on the surface of the laundry, and the vibrating horn 212 is in contact with the water layer.

When the amount of water in the water storage tub 40 decreases due to water absorption by the laundry and the water level drops so that the opening 134a of the cover 134 is no longer blocked by detergent water, detergent water is supplied from the storage box 111 to the water storage tub 40 until the opening 134a. Again clogged with detergent water. Thereby, the water level in the water tank 40, that is, the water volume is maintained in an appropriate state.

When a predetermined standby time elapses after the supply valve 117 is opened, the ultrasonic vibrator 211 is energized to operate the ultrasonic generator 210 . Ultrasonic waves are generated from the tip of the vibrating horn 212, and dirt is peeled off from the laundry by the action of the ultrasonic waves. At this time, since the potency of the detergent increases, the detergency improves.

When a predetermined operating time elapses after the operation of the ultrasonic generator 210, the operation of the ultrasonic generator 210 is stopped, and the ultrasonic cleaning operation is completed.

The user removes the drain plug 43 from the drain port 42 to open the drain port 42 . When the drain port 42 is opened, the detergent water in the water storage bucket 40 flows to the drain hose 50 and is discharged outside the machine. At this time, the supply valve 117 is opened, and the detergent water remaining in the storage box 111 is also discharged outside the machine through the water storage tank 40 and the like.

Next, when the user washes the laundry by hand, if the ultrasonic cleaning unit 200 is located at the use position, it moves to the retracted position, and operates the detergent water supply in the state where the ultrasonic cleaning unit 200 is located at the retracted position. button62. As a result, automatic water supply into washing tub 30 is started under the control of control unit 70 .

First, detergent water is supplied into the water tank 40 by the first water supply unit 110 of the water supply device 100 as in the case of the ultrasonic cleaning operation.

Next, pure water is supplied by the second water supply unit 120 of the water supply device 100 . That is, the second water supply valve 121 is opened, and the pure water from the faucet flows through the second water passage portion 122 and is discharged from the second introduction port 132 into the junction portion 130 . The discharged pure water merges with the detergent water, and then flows to the water storage tank 40 through the connection part 140 and the water supply port 41 , overflows from the water storage tank 40 together with the detergent water, and is stored in the washing tank 30 . The pure water is mixed with the detergent water and the detergent water is diluted to produce diluted detergent water having a lower detergent concentration than the detergent water. In this embodiment, the pure water and the detergent water are easily mixed by combining the pure water and the detergent water at the merging portion 130 . Thereby, the concentration of the diluted detergent water stored in washing tub 30 becomes easy to be uniform.

When the water level in washing tub 30 rises to reach a predetermined water level L shown by a dashed-dotted line in FIG. 2 , the water level is detected by water level detection device 80 . Thereby, the second water supply valve 121 is closed, and the water supply from the second water supply unit 120 is stopped. The predetermined water level L is a water level slightly lower than the height position of the overflow port 32 . In addition, the height position of the overflow port 32 is lower than the height position of the second introduction port 132 of the confluence part 130 .

It should be noted that the inside of the cover part 134 , the first inlet 131 and the connection pipe 118 are filled with detergent water, and the opening 134 a of the cover part 134 is provided facing downward. Therefore, the diluted detergent water stored in washing tub 30 does not flow back into first water supply unit 110 from first inlet 131 located at a position lower than predetermined water level L. FIG.

In this way, when the diluted detergent water is stored in the washing tub 30 , the laundry is hand-washed or the like in the washing tub 30 using the diluted detergent water. That is, the laundry is washed by the user's hands.

After washing the laundry, the user removes the drain plug 43 from the drain port 42 and opens the drain port 42 . The diluted detergent water in the washing bucket 30 is discharged from the drain port 42 and flows out of the machine through the drain hose 50 . Furthermore, the detergent water remaining in the storage box 111 is also discharged to the outside of the machine.

In addition, when pure water is released from the 2nd introduction port 132, pure water may hit the cover part 134 grade|etc., and may splash upward. In this embodiment, it is arranged so that the air of the confluence part 130 escapes from the labyrinth-like gap created by inserting the cylindrical part 14 of the top surface part of the case 10 into the opening 130a of the confluence part 130, so that the splashed water It is not easy to leak out from the junction portion 130 .

Moreover, when the water supply does not stop due to the abnormality of the second water supply valve 121 and the water level detection device 80, and the water level in the washing tub 30 exceeds the height of the overflow port 32, the diluted detergent water will overflow from the overflow port 32 and It is discharged outside the machine through the overflow hose 54 and the drain hose 50 . Accordingly, it is possible to prevent diluted detergent water from overflowing from washing tub 30 or from flowing back from second inlet 132 to second water passage portion 122 .

Next, the user operates the water supply button 64 to rinse the washed laundry with pure water. The pure water is supplied only by the second water supply unit 120 , and the pure water is stored in the washing tub 30 up to a predetermined water level L. When the rinsing is completed, water is drained from the washing tub 30 .

It should be noted that, before water is supplied by the second water supply unit 120, the supply valve 117 is closed. Thus, the air filled in the cover portion 134, the first inlet 131 and the connecting pipe 118 has nowhere to escape, so the pure water stored in the washing tub 30 will not flow from the opening 134a of the cover portion 134 to the first water supply portion. 110 medium countercurrent.

Next, when the chemical water is used to process the laundry in the washing tub 30, the chemical water supply button 63 is operated. In the case of rinsing with water containing a softener afterward, in the case of bleaching laundry with water containing a bleaching agent while storing a liquid bleach in the second chemical cartridge 160 in advance, and the like.

With the same operation of the water supply device 100 as in the case of hand washing, after the chemical water, that is, the water containing softener and bleach is supplied from the first water supply unit 110 , pure water is supplied from the second water supply unit 120 to the inside of the washing tub 30 . Reserve the chemical water diluted with pure water to the specified water level L.

However, unlike the case of hand washing, in the first water supply unit 110 , in order to supply medicinal water into the storage box 111 , the second three-way valve 116 is switched so that the second supply pipe 165 and the first water channel in the first water channel 113 are connected to each other. The downstream side of the second three-way valve 116 is in communication, and the first three-way valve 115 is switched to a state in which the upstream side and the downstream side of the first three-way valve 115 in the first water passage portion 113 are in communication. Accordingly, when the supply pump 112 operates, the liquid softener and liquid bleach, which are the liquid medicines in the second medicine cartridge 160 , are sucked into the first water passage portion 113 .

When the treatment of the laundry using chemical water is completed, water is drained from the washing tub 30 .

As described above, according to the present embodiment, the following effects can be achieved.

The cleaning device 1 is equipped with: a cleaning bucket 30, which stores water for cleaning the laundry; a water storage bucket 40, which is located inside the cleaning bucket 30, can store water, and has an opening area smaller than that of the cleaning bucket 30; and ultrasonic cleaning The part 200 is located above the water storage tank 40 and applies ultrasonic waves to a part of the laundry soaked in water in the water storage tank 40 to clean the part.

In addition, since the water storage tank 40 having an opening area smaller than that of the cleaning tank 30 is provided and water is stored in the water storage tank 40 when ultrasonic waves are used for partial cleaning, the parts to be cleaned according to the laundry are soaked. In terms of water storage at a certain depth, the required amount of water is reduced, which can prevent wasted water. In addition, since the water storage tub 40 is located inside the washing tub 30 , water is less likely to scatter out of the washing apparatus 1 when the laundry is partially cleaned by ultrasonic waves.

In the cleaning device 1 , the water storage tank 40 is formed on the bottom surface of the cleaning tub 30 by partially recessing the bottom surface.

According to this configuration, the water storage tub 40 can be easily formed by partially recessing the bottom surface in the inside of the washing tub 30 . In addition, the water storage tub 40 is less likely to interfere with washing the laundry in the washing tub 30 . Furthermore, when the laundry is partially cleaned by ultrasonic waves, it is extremely difficult for water to scatter out of the cleaning device 1 .

In the cleaning device 1, the water supply device 100 includes: a first water supply unit 110, which supplies detergent water; a second water supply unit 120, which supplies pure water; and a confluence unit 130, which supplies detergent water from the first water supply unit 110 and Pure water from the second water supply unit 120 merges. In the confluence portion 130 , a first inlet 131 through which detergent water flows is provided on a side wall surface, and a second inlet 132 through which pure water flows is provided at a position higher than the first inlet 131 . The first introduction port 131 is covered from the inside of the confluence part 130 by a cover part 134 having a downward opening 134 a.

According to this configuration, detergent water can be supplied into water tank 40 , and diluted detergent water obtained by diluting detergent water with pure water can be supplied into washing tub 30 . Accordingly, parts of the laundry can be washed with ultrasonic waves using detergent water with a high detergent concentration, and diluted detergent water generated from the detergent water can be used for hand washing in washing tub 30 , and the like.

Furthermore, by merging the pure water and the detergent water at the merging portion 130, the pure water and the detergent water are easily mixed. Thereby, the concentration of the diluted detergent water stored in washing tub 30 becomes easy to be uniform. Moreover, the first inlet 131 is covered from the inside of the confluence portion 130 by the cover portion 134 having the downward opening 134a, so that the diluted detergent water stored in the washing tub 30 can be prevented from flowing from the first inlet 131 to the first inlet. Reverse flow in the water supply unit 110 .

The washing device 1 also has a drain port 42 provided in the water storage tank 40 . According to this configuration, water can be drained from the inside of the water tank 40 through the water outlet 42 , and water can also be drained from the inside of the washing tub 30 through the water tank 40 . Thereby, the drainage path for draining the water from the washing tub 30 and the water tank 40 can be shared.
