The control unit 80 includes a control circuit of the ultrasonic cleaning unit 73.

The operation of the washing machine 1 with the partial washing device is as follows. In a state where the partial washing device 70 is stored under the upper surface plate 11, the laundry is thrown into the washing tub 30 from the laundry slot 15, the lid 16 is closed, and a group of operation buttons provided on the upper surface of the main body 2. When a washing course is selected by operating (not shown) and the operation is started, the automatic operation of the washing machine 1 is started. First, the amount of the laundry is determined, and then the washing tub 30 is supplied with water through the water supply nozzle 52. At this time, the drain valve 66 is closed. The water level switch 55 monitors the water level in the washing tub 30. The water level switch 5 indicates that an amount of water corresponding to the amount of laundry has been poured into the washing tub 30.
The water supply valve 50 is closed at the time when the water supply valve 5 detects. At this time, the water in the washing tub 30 becomes a washing liquid in which the detergent is dissolved by mixing the detergent before being discharged from the water supply nozzle 52.

Subsequently, a washing process is started. In the washing process, the motor 41 rotates the pulsator 33, and the rotation of the pulsator 33 causes the washing liquid to flow to wash the laundry. At this time, the dehydrating shaft 44 is braked by the brake device 43, and the washing tub 30 does not rotate even if the washing liquid and the laundry move. After a lapse of a predetermined time, the motor 41 stops, the pulsator 33 stops rotating, and the drain valve 66 opens. The washing liquid in the washing tub 30 is drained through the drainage space 64. When a predetermined time has elapsed and most of the washing liquid has drained from the laundry, the clutch device 42 is switched, and the motor 41 rotates the spinning shaft 44 this time. As a result, the washing tub 30 rotates at a high speed. At this time, the pulsator 33 also rotates with the washing tub 30.

When the washing tub 30 rotates at a high speed, the laundry is pressed against the inner peripheral wall of the washing tub 30 by centrifugal force. The washing liquid contained in the laundry also collects on the inner surface of the peripheral wall of the washing tub 30, but as described above, the washing tub 30 is spread upward in a tapered shape. 30
Rises inside. The washing liquid is discharged from the water discharge port 31 when reaching the upper end of the washing tub 30. The washing liquid that has left the water discharge port 31 is beaten to the inner surface of the water tub 20 and flows down to the bottom of the water tub 20 along the inner surface of the water tub 20. And the branch pipe 60a and the drainage hose 60 following it
And is discharged out of the main body 2.

After the laundry is sufficiently dehydrated, the drain valve 66 is closed, and rinse water is injected from the water supply nozzle 52 this time. When a predetermined amount of rinse water is accumulated in the washing tub 30, the pulsator 3
Rotate 3 to shake the rinse water and the laundry to dissolve the dirt and detergent components remaining in the laundry into the rinse water. After a lapse of a predetermined time, the pulsator 33 is stopped, the drain valve 66 is opened, and the rinse water is drained. Then, the washing tub 30 is dewatered and rotated to rinse off washing water from the laundry. Such rinsing and dehydration operations are repeated a predetermined number of times, and when the last dehydration is completed, the entire washing process is terminated.

In the above description, "rinse" is performed in which rinsing water is stored in the washing tub 30 and rinsing is performed.
In some cases, “shower water injection” is performed, in which water is poured from 2. Either or both are determined by the washing course and the amount of laundry.

If the dirt is not removed after washing, or if there is severe dirt that is known in advance not to be clean in a normal washing course, the partial washing device 70 is used to remove the dirt. Clean only spots. That is, the partial washing device 70 is displaced from the storage position indicated by the broken line in FIG. 22 to the use position indicated by the solid line, and the ultrasonic vibration unit 73 is driven while the cleaning liquid flows out. When the soiled portion of the laundry is passed through the gap 74 in this manner, the soiled portion is cleaned by the interaction between the ultrasonic wave and the cleaning liquid. After the partial washing is sufficiently completed, the laundry is put into the washing tub 30. If the washing process has been completed before the partial washing, only rinsing and dehydration are performed thereafter, and if the washing process has not been completed, washing is started from the washing process.

Japanese Patent Application Laid-Open No. 2000-24362 describes a cloth cleaning apparatus which can be used as a partial washing apparatus of a washing machine. In this cleaning device, the vibrating horn of the ultrasonic wave generating means is surrounded by a guard so that a finger does not contact the vibrating horn. The portion to be washed of the laundry is brought into contact with the vibration horn through a slit provided in the guard.

When ultrasonic cleaning is adopted as a cleaning method of the partial washing apparatus, how to secure safety at home becomes a problem. If you touch the ultrasonic vibration horn,
In addition to feeling pain in the hands, the cartilage may be adversely affected due to the use of the frequency range that reaches deep into the human body. Therefore, first of all, it is necessary to consider preventing a finger from touching the vibration horn. JP-A-2000-24 mentioned above
If the vibrating horn is surrounded by the guard portion and the portion to be washed of the laundry is inserted from the slit portion as in the cleaning device described in Japanese Patent No. 362, the possibility that the finger contacts the vibrating horn is considerably reduced. However, considering the washing of thick cloth such as denim, the slit must have a certain width, and the danger that a child's thin finger enters from here and comes into contact with the vibration horn cannot be denied.

The tray detecting means 131 detects whether or not a tray, which will be described later, exists below the partial washing apparatus 100, and is constituted by a reflection type optical sensor.

Reference numeral 132 denotes a cleaning liquid tube provided in the case 101. The cleaning liquid tube 132 has a bifurcated water injection part 132a at the tip. The water injection parts 132a are arranged on both sides of the vibration horn 114 as shown in FIG. 9, and the cleaning liquid is poured on both sides of the head part 116.

Wiring 13 to ultrasonic vibration device 111
3. The wiring 134 to the hand lighting means 130, the wiring 135 to the tray detecting means 131, and the cleaning liquid tube 132 are formed in the slit 13 formed in the bearing 104 and the support shaft 142.
6 and 137, and enters the spindle 142. In other words, the inside of the support shaft portion 142 serves as a wiring for communication and power supply, or a duct 142a through which a pipe for water supply (liquid supply) passes. As the partial washing device 100 rotates, the wiring 133,
Since the 134 and 135 and the cleaning liquid tube 132 also move, the slits 136 and 137 are set to a length that allows the movement.

Reference numeral 138 denotes a control circuit section of the partial washing device disposed inside the base 140. This control circuit section 138
The wiring 133, 134, 13 that has passed through the duct 142a
5 and a wiring (not shown) connected to the position detecting device 170. The control circuit section 138 also includes an ultrasonic transmission circuit of the ultrasonic vibration device 111. A wiring 139 for connecting to the control unit 80 is derived from the control circuit unit 138. After the wiring 139 and the cleaning liquid tube 132 pass through the hole 12a formed in the back panel 12 and come out below the back panel 12, they are guided to a place where they should be connected.

The water supply valves 50 are independently opened and closed valve portions 5.
0a and 50b. One valve portion 50a is connected to the water supply nozzle 52 shown in FIG. The other valve portion 50b is connected to a water supply joint 56, and a cleaning liquid tube 132 is connected to the water supply joint 56. Water supply joint 56
Is provided with a drain valve 57 as a drain means. When the drain valve 57 is opened, the water supply joint 56 and the cleaning liquid tube 132 are opened.
The water remaining inside is discharged between the water tub 20 and the washing tub 30.

With the partial washing device 100 mounted on the outer surface of the main body 2A, the structure of the lid 16 is also changed. First, a notch is formed in the rear lid 16b larger than the side hinged by the shaft 18 to form a gate opening 180 for allowing the partial washing apparatus 100 to pass through. The rear lid 16b itself has a gate-like shape. The gate opening 180 is
When the partial washing device 100 is pulled out to the position at the time of use, the rear lid 16b does not interfere with the partial washing device 100.
(The “height” when the rear lid 16b is upright).

When the rear lid 16b is raised and the front lid 16a is folded back at the axis 17 to fold the entire lid 16 in half as shown in FIG. 1, the front lid 16a is prevented from hitting the partial washing device 100. The dimensional relationship between the rear cover 16a and the rear cover 16b is set. In terms of Figure 2, the depth L ₁ of the front lid 16a is made smaller than the depth L ₂ of the rear lid 16b. L ₁ and dimensional ratio of L ₂ is, L ₁ is set to be 50-80% of L _2. In this way, even when the partial washing device 100 is placed at the storage position, the front lid 16a can be
Avoid hitting.

In the gate opening 180, a tray 181 for receiving laundry is arranged. The tray 181 has a gate opening 180
And is applied to the rear lid 16b from below, as shown in FIG. As shown in FIG. 14, the tray 181 is hinged to the rear lid 16b by shafts 182 protruding from both sides thereof. The axis of the shaft 182 coincides with the axis of the shaft 18 hinged to the upper plate 11 with the rear lid 16b. Therefore, the tray 181 rotates in a vertical plane similarly to the rear lid 16b.

As shown in FIGS. 4 and 5, projections 183 are formed on both sides of the tray 181, and the projections 183 engage with the edge of the laundry inlet 15. Therefore, the tray 181
Does not fall below the laundry inlet 15.

The tray 181 has a depressed upper surface, but only a central portion is a higher pedestal portion 184. The cradle part 184 is the partial washing device 1 in the position at the time of use.
Facing the washing section 110 of 00. On both sides of the receiving base 184, the bottom surface of the tray 181 is inclined so as to become lower toward the rear. Then, a drain port 185 is formed at the lowest point on both sides of the receiving part 184. As shown in FIG. 1, a gutter 186 that receives water drained from a drain port 185 is provided inside the main body 2. The gutter 186 itself has a drain port 187 so that the received water falls between the water tub 20 and the washing tub 30.

A removable connecting means 190 is provided between the rear lid 16b and the tray 181. The mechanism will be described with reference to FIG. First, a hook 192 is attached to the lower surface of the rear cover 16b (the surface facing the front when the rear cover 16b is raised) by the shaft 191.
Is hinged. The hook 192 is rotatable in a vertical plane.
It is urged to the position shown in FIG. On the other hand, the free end of the tray 181 is formed with a projection 193 that engages with the hook 192. Engagement surface of hook 192 with projection 193 and projection 1
The engaging surface of the hook 93 with respect to the hook 192 is inclined so that an appropriate force is required to release the engagement, and the engagement is released when an appropriate force is applied.

The upper plate 11 is provided with a locking means 200 for locking the lid 16 in a closed state. The structure of the locking means 200 is shown in FIG.
5 is shown in a partially enlarged view added thereto. Locking means 2
00 is composed of a solenoid 201 and a solenoid 2
In order to dispose 01, a pocket portion 202 is formed at a position corresponding to the front edge of the laundry inlet 15 of the upper surface plate 11. The pocket portion 202 is raised upward and opened downward. A hanging piece 203 is formed on the front lid 16a so as to overlap the front surface of the pocket 202. The solenoid 201 is arranged in the pocket 202, and the plunger 204 protrudes from the front of the pocket 202. A hole 205 for engaging the plunger 204 is formed in the hanging piece 203. With the lid 16 closed, the control unit 80
As a result, the solenoid 201 is excited, and when the plunger 204 protrudes and engages with the hole 205, the lid 16 cannot be opened. When the excitation of the solenoid 201 is released, the plunger 204 is displaced to the retracted position, and
If it is not 5, the lid 16 can be opened. In addition, the upper surface plate 11 is formed with a concave portion 11a for making it easy to put a finger on the front edge of the front lid 16a.

The top plate 11 is further provided with a lid open / closed state detecting means 210 for detecting the open / closed state of the lid 16. FIG. 14 shows the configuration of the lid open / closed state detecting means 210. The switch 211 disposed near the center of rotation of the rear lid 16b and the arm 212 protruding from the rear lid 16b constitute a lid open / closed state detecting means 210. When the lid 16 is closed, the arm 212 contacts and moves the actuator 213 of the switch 211. As a result, the switch 211 emits a signal, and the signal is transmitted to the control unit 80. When the lid 16 is opened, the arm 212 separates from the actuator 213 and the switch 21
1 is switched, and a different signal is transmitted to the control unit 80.

Both the switch 211 and the arm 212 have the upper plate 1
1 below. Arm 212 and actuator 21
3, the arm 212 may be in contact with the actuator 213 when the lid 16 is opened, and the arm 212 may be separated from the actuator 213 when the lid 16 is closed.

The upper surface on the front side of the upper surface plate 11 is
0 (see FIGS. 2 to 5). In the operation panel section 90, in addition to a group of operation buttons for controlling the operation of the main body 2, such as a driving button and a washing course selection button, display means for indicating the operation state of the main body 2A is arranged. The display means includes a liquid crystal display panel and an LED lamp.

The group of operation buttons on the operation panel 125 of the partial washing apparatus 100 and the group of operation buttons on the operation panel section 90 of the main body 2A are pressed by pressing a predetermined one of them in a specific pattern. Alternatively, the main body 2A can perform a predetermined operation.
The operation will be described sequentially in the following description of the operation. Note that "pressing a predetermined object in a specific pattern" means "multiply pressing a predetermined object" or "continuously pressing a predetermined object". "Multiple push"
This means that a plurality of different operation buttons are pressed simultaneously or sequentially within a predetermined short time. “Continuous pressing” means that one operation button is continuously pressed for a predetermined time (for example, 2 seconds), or a plurality of different operation buttons are simultaneously or sequentially pressed for a predetermined time. “Pressing in a normal pattern” refers to a pressing method in which a finger is immediately released after being pressed.

Next, the operation of the washing machine 1A with a partial washing device according to the first embodiment will be described. Washing tub 3 in body 2A
Since the washing operation performed using 0 is not different from that of the conventional washing machine 1 with a partial washing device, the description is omitted. In addition,
Washing is performed by placing the partial washing device 100 in the storage position.

When the laundry is partially stained after washing, or when soil which cannot be controlled by ordinary washing is found in advance, the partial washing apparatus 100 is used. The partial washing device 100 cannot be used when it is in the storage position. This is because a signal indicating that the partial washing device 100 is in the storage position is sent from the position detection device 170 to the control circuit unit 138 or the control unit 8 that controls the control circuit unit 138.
This is because the state is transmitted to 0, and the partial washing apparatus 100 is in the operation prohibited state. Therefore, first, the locking means 160
Must be released and the partial washing apparatus 100 must be turned 90 ° in a horizontal plane to be displaced to the position in use.

The rotation of the partial washing apparatus 100 is performed with the lid 16 closed. This is because, when the lid 16 is open, the tip of the partial washing device 100 hits the root of the lid 16 (the root of the rear lid 16b) when the partial cleaning device 100 is rotated from the storage position. is there. When the partial washing device 100 pivots over the closed lid 16 and reaches the angle of use, the locking means 160 re-engages to maintain the partial washing device 100 in that position. The position detecting unit 170 detects that the partial washing apparatus 100 has reached the position at the time of use, and sends a signal to the control circuit unit 138 and the control unit 80. The position detecting means 170 may perform the detecting operation when the power switch of the washing machine 1 with the partial washing device 1 is turned on.

Upon receiving a signal indicating that the partial washing apparatus 100 has reached the position at the time of use, the control circuit section 138 operates the tray detecting means 131. Tray detecting means 131 is tray 1
It is detected whether or not 81 exists under the partial washing apparatus 100 in a state where it can be used without being damaged or dropped. When it is determined that the ultrasonic wave transmission circuit exists in a state that can be used, the control circuit unit 138 puts the ultrasonic transmission circuit in an operable state, and turns on the operation status display unit 128 and the hand illumination unit 130. The tray detection means 131 may be configured to start operating when the operation button 126 of the partial washing device 100 is pressed.

When the tray detecting means 131 cannot detect the existence of the tray 181 because the tray 181 has been damaged or has fallen off, the operating status display means 128 blinks or lights up in a different color. To notify the user of the abnormality. Run button 126 and intensity setting button 127
Does not accept any operation, and the partial washing apparatus 100 becomes inoperable.

The work of detecting the tray 181 is performed by the partial washing device 1
The position detecting means 170 detects that 00 has reached the position in use.
Is detected, that is, the actuator operation protrusion 17
3 starts after the actuator 3 contacts the actuator 172.
Alternatively, if the setting is such that the operation starts when the operation button 126 is pressed, the operation is started after the operation button 126 is pressed. The detection operation is performed within a predetermined short time (for example, 0.5 to 1 second) from the start of detection. The reason for limiting the time is that when the tray 181 is damaged or dropped, a finger may come into contact with the vibration horn 114, and it is necessary to quickly determine that the vibration horn 114 is not vibrated. is there.

When the operation status display means 128 lights up normally, the lid 16 is opened. When the lid 16 is lifted, the connecting means 190
And the tray 181 is lifted. The lifted tray 181 hits the partial washing device 100. The partial washing device 100 has a displacement mode other than rotation in a vertical plane,
In this case, the displacement is performed by the rotation in the horizontal plane, and the partial washing apparatus 100 cannot be lifted by the tray 181. Therefore, when the tray 181 hits the partial washing device 100, the tray 181 is prevented from following the lid 16, the connecting means 190 is released, and the lid 16 continues to rotate, but the tray 181 is not rotated.
Will remain below. The tray 181 remaining behind the receiving portion 184 and the washing portion 110 of the partial washing device 100 is engaged with the protrusion 183 engaging with the edge of the laundry input port 15.
Are held in a state where there is a gap between the two. This gap has a width of 5 to 13 mm as described above, and laundry can enter, but a finger cannot easily enter. Therefore, the risk of a finger touching the vibration horn 114 that is ultrasonically vibrating is small.

When the lid 16 is completely opened, it is folded in half. Even in this case, as described above, the front lid 16
a does not contact the partial washing device 100. In a situation where an obstacle is approaching on the main body 2A as shown in FIG. 1, the lid 16 is opened while the posture conversion to the folding is advanced.

The locking means 200 locks the lid 16 in a closed state in order to prevent a hand or the like from touching the washing tub 30, the pulsator 33, the laundry and the like in a washing step or a dehydrating step. Can also be used. That is, when the partial washing device 100 is in the storage position or the use position, the lid 16 can be opened and closed without interfering with the partial washing device 100. However, if the partial washing device 100 is located at any other angle position, the lid 16 and the partial washing device 100 may interfere with each other depending on the angle.
Therefore, the position detecting means 170 detects whether the partial washing device 100 is at the storage position or the use position. This can be easily realized by adding another actuator operation projection 173. When the partial washing device 100 is located between the position at the time of storage and the position at the time of use and the position detecting means 170 does not emit a signal, it is determined that there is a danger of interference when the lid 16 is opened, and the lid 16 is opened. It is locked by the locking means 200. When the partial washing device 100 is displaced to the storage position or the use position and the position detection means 170 issues a signal, the locking means 2
Unlock by 00.

The reason why the lid 16 was opened with the partial washing apparatus 100 placed at the time of use is that if the lid 16 is still closed,
The cleaning liquid poured into the partial washing device 100 is the upper surface of the lid 16,
This is because the floor may be wet.

After the preparation for using the partial washing apparatus 100 is prepared, the laundry is placed on the tray 181 and the operation button 126 on the operation panel 125 is pressed. As aforementioned,
Only a momentary press of the operation button 126 causes the partial washing device 1
00 does not start operation. The operation is finally started by pushing continuously for a predetermined time. Thereby, it is possible to avoid the danger of starting operation due to accidentally touching the operation button 126 or pressing the operation button 126 by a child playing prank. After the tray 181 is detected, when the operation of the partial washing apparatus 100 is started by the operation button 126, the tray detection unit 131 starts the detection operation. This redetection is performed to check whether the tray 181 has not been damaged due to the weight of the laundry or the pressure of the user's hand. Predetermined time (for example, 1 to 10 minutes)
If no abnormality is detected during this period, the power of the tray detection means 131 may be automatically turned off or the oscillation operation may be stopped.

When the operation of the partial washing device 100 is started, the valve portion 50b of the water supply valve 50 is opened, and the washing liquid tube 1 is opened.
32 is supplied with a predetermined amount of water, for example, 50 to 300 cc / min. Water is supplied from the water injection section 132a to the vibration horn 11
4 are poured into both sides of the slit 123 and the cleaning droplet
24 drip onto tray 181. Subsequently, the ultrasonic vibration device 111 starts ultrasonic vibration. In this way, the laundry is inserted into the gap between the vibration horn 114 and the receiving base 184, and is slowly reciprocated. Ultrasonic waves concentrate on the laundry, and the dirt components are peeled off. Applying a liquid detergent to the contaminated area further enhances the cleaning effect. The separated dirt component flows out of the drain 185 together with the water, is received by the gutter 186, falls through the drain 187 of the gutter 186 into the gap between the water tub 20 and the washing tub 30, and is discharged from the drain hose 60 into the main body 2.
It is discharged outside.

During the operation of the partial washing apparatus 100, the operation status display means 128 is turned on to notify the user that ultrasonic waves are being generated. The intensity of the ultrasonic cleaning can be switched by the intensity setting button 127. Further, since the hand illuminating means 130 is turned on, it is possible to closely examine whether dirt has been removed. The hand illuminating means 130 is automatically turned on during operation of the partial washing apparatus 100,
A separate ON / OFF switch may be provided to turn on manually only when desired.

In the above configuration, simple water is poured from the water injection section 132a, but it is also possible to add an additive such as a detergent to the water to improve the cleaning effect. This can be realized by providing an additive mixing section in the middle of the cleaning liquid tube 132, or by connecting the cleaning liquid tube 132 to a separately provided cleaning liquid tank.

After the partial washing is completed, the laundry is put into the washing tub 30 and washing is started again, or rinsing and dehydration are performed without washing. For safety,
The partial washing apparatus 100 is operated for a predetermined time (for example, 3
It is preferable that the switch is automatically turned off after a lapse of 10 minutes.

To perform washing and rinsing, the lid 16 must be closed. The lid 16 is closed by the partial washing device 10.
0 is left in the position at the time of use. When the partial washing device 100 is located between the position at the time of use and the position at the time of storage, the lid 16 is not opened and closed because the partial washing device 100 and the lid 16 may interfere with each other.

When the lid 16 is closed, the connecting means 190 enters a connected state. If the partial washing device 100 has returned to the storage position, the tray 181 opens and closes integrally with the lid 16 thereafter.

The washing machine 1A with a partial washing device according to the first embodiment can be modified in its partial configuration as described below.

First, the locking means of the partial washing device 100 will be described. This can be configured as shown in FIG. FIG.
The locking means 160a shown in FIG. 6 does not have a manual part, and the plunger 167 of the solenoid 166 causes the
Is locked. The plunger 167 is engaged with a hole 169 of the support shaft 142 through a hole 168 provided in the bearing 104. Like the holes 163 and 164 shown in FIG. 8, two holes 169 are provided at an angular interval of 90 °. When the plunger 167 is engaged with any of the holes 169, the partial washing device 100 is maintained at the storage position or the use position. When the excitation state of the solenoid 166 changes and the plunger 167 comes out of the hole 169, the partial washing device 100 can be rotated.

Either the manual locking means 160 or the solenoid locking means 160a may be used alone, or both may be used in combination.
Although the manual locking means 160 is provided in the base 140 and the solenoid locking means 160a is provided in the partial washing device 100, the positional relationship can be exchanged.

The connecting means between the rear lid 16b and the tray 181 can be as shown in FIG. The connecting means 190a shown in FIG. 17 includes a pair of suction means 194a and 194b.
Are mounted separately on the rear lid 16b and the tray 181. One of the suction means 194a and 194b is made of a magnet, and the other is made of a magnetic material such as iron. Alternatively, both may be magnets. Suction means 194a, 194b
Of the partial washing apparatus 100 to such an extent that the tray 181 is lifted following the rear lid 16b.
Is set to such an extent that the suction is cut off when the pressure is applied.

The connecting means is not provided, and the tray 18 is
1 may follow the rear lid 16b. FIG.
19 shows the structure. A torsion coil spring 188 is wound around a shaft 182 that hinges the tray 181 to the rear lid 16b. One end of the torsion coil spring 188 is a tray 181.
And the other end is engaged with the rear lid 16b, and the gate opening 1 is engaged.
The tray 181 is biased to a position where the tray 80 is closed. Thereby, the tray 181 opens and closes integrally with the rear lid 16b. When the partial washing device 100 is hit, the tray 181 is kept in place. The tray 181 can be biased using a spring other than the torsion coil spring, for example, a compression coil spring or a tension coil spring.

When the tray 181 is configured to be biased by a spring, the tray 181 and the partial washing device 100 are prevented in order to prevent the receiving base 184 from being in close contact with the vibration horn 114 and eliminating a gap through which the laundry passes. It is preferable to form a projection on one or both of them, and to ensure that an appropriate gap is secured between the pedestal part 184 and the vibration horn 114 by contacting the projection with the other party. This projection is placed in a place where it does not obstruct the passage of the laundry.

The connecting means may be of a solenoid type. That is, the same solenoid as that used for the locking means 200 is mounted on either the rear lid 16b or the tray 181, and the other is provided with a hole with which the plunger of the solenoid engages. The control unit 80 controls this solenoid as follows. That is, the solenoid keeps the rear lid 16b and the tray 181 connected while the position detecting means 170 detects that the partial washing apparatus 100 is at the storage position.
When the position detecting means 170 detects that the partial washing device 100 has been displaced to the position at the time of use, the solenoid operates the rear lid 16.
The connection between the tray b and the tray 181 is disconnected, and the tray 181 is left at the edge of the laundry inlet 15. When the lid 16 is closed after the partial washing operation is completed and the partial washing device 100 returns to the storage position, the controller 80 switches the excitation state of the solenoid upon receiving a signal from the lid open / closed state detection means 210,
The rear cover 16b and the tray 181 are connected again.

The tray 181 may be supported not by the rear lid 16b but by the top plate 11. Top plate 1
1, a bearing portion is formed, and the shaft portion of the tray 181 is attached to the bearing portion.
In this case, the axes of the shaft 18 and the shaft 182 are aligned with each other so that the movement does not have to be natural.

In the foregoing, it has been described that the rotation of the partial washing apparatus 100 is performed with the lid 16 closed. This is because, when the lid 16 is open, when the partial washing device 100 is to be rotated from the stored position to the used position or vice versa, the tip of the partial washing device 100 is closed.
This is because it hits the base of No. 6 (the base of the rear lid 16b). However, by adjusting dimensional factors such as the width of the gate opening 180, the length (turning radius) of the partial washing device 100, and the position of the center of rotation of the partial washing device 100, the lid 1 is adjusted.
Even when 6 is open, it is possible to rotate the partial washing device 100 without causing interference with the lid 16.

Further, a configuration in which the partial washing apparatus 100 is of a fixed type is also possible. That is, the washing unit 110 is
The partial washing device 100 is fixed while keeping the shape facing the laundry input port 15 from the outside of A. In this way, the component provided with the partial washing apparatus 100 being movable, such as the position detecting means 170 of the component washing apparatus 100, or the connecting means between the rear lid 16b and the tray 181 190 can be eliminated. In the case of this configuration, the tray detection unit 131 starts detection when the operation button 126 of the partial washing device 100 is pressed. Completion of the detection operation within a predetermined short time is the same as in the case of the movable partial washing device 100. Tray 18
1 is detected, the partial washing apparatus 100 starts operating as it is. If the presence of the tray 181 is not detected, the partial washing apparatus 100 becomes inoperable, and the operating status informing means 128 blinks or lights up in a different color to notify the user of the abnormality.

Now, a child lock can be set in the partial washing device 100. When the user performs a specific operation, the control unit 80 sets a child lock. When the child lock is set, the partial washing device 10
Of the operation buttons including the 0 operation button 126 (including both the operation button group on the side of the partial washing device 100 and the operation button group on the side of the main body 2A), unless a predetermined button is pressed in a specific pattern The operation of the partial washing device 100 cannot be started. “Pressing in a specific pattern” means, as described above, that the operation button is pressed multiple times or continuously.

First, in order to set the child lock, it is necessary to first press a predetermined operation button in a specific pattern. When the predetermined operation button is pressed in another specific pattern during the child lock setting, the operation of the partial washing device 100 is started. In order to stop the operation of the partial washing device 100 during the child lock setting, "specific pattern pressing" is not required. If the operation button 126 is pressed in a normal pattern, the operation of the partial washing apparatus 100 can be stopped therewith. When the child lock becomes unnecessary, the child lock can be released by pressing a predetermined operation button in a specific pattern set for release.

In setting the "predetermined operation button", the user selects from both the operation button group on the side of the partial washing apparatus 100 and the operation button group on the main body 2A. Only the operation buttons on the side of the partial washing device 100 may be selected, or only the operation buttons on the main body 2A may be selected. One of the operation buttons on the side of the partial washing device 100
It is also possible to select one operation button, select another operation button from the operation button group of the main body 2A, and combine them.

When the child lock is set, the operation button 12
When 6 is pressed in the normal pattern, the operation status display unit 128 performs a display different from the normal display similarly to when the tray detection unit 131 cannot detect the presence of the tray 181, and the partial washing device does not operate due to the child lock state. Notify that. Thereby, the user recognizes that he / she has performed an incorrect operation. At this time, it is desirable that the notification mode of the operation status display means 128 be different from the notification mode when the tray is not present. It may be displayed in characters or notified by voice.

When the child lock is set when the lid 16 is closed, and the partial washing apparatus 100 is operated while the child lock is set, the locking means 200 operates.
The lid 16 is locked in the closed state. This is done when the child does not want to look into the washing tub 30 during the partial washing. As usual, when the washing tub 30 is desired to receive the scattered washing liquid, the locking means 200 does not lock only by setting the child lock, so the lid 16 is opened before the operation of the partial washing apparatus 100 is started. Then, the operation of the partial washing device 100 is started. Even at this time, the partial washing device 1
