BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine equipped with a partial washing device capable of partially washing laundry.

[0002]

2. Description of the Related Art A washing machine (electric washing machine) normally puts laundry in a washing tub and causes it to flow in a washing tub together with water in which detergent is dissolved (forming a swirl, stirring. Do) or rotate the washing tub itself to wash. As a result, the laundry put in the washing tub is washed all at once, and a uniform washing effect is exerted on each part of the laundry. However, in the case of heavily soiled items such as collars and cuffs, or spots that have stains, the above-mentioned simultaneous washing may not sufficiently remove the stains. It was necessary to wash the hand only at the relevant part.

Therefore, in addition to the usual washing tub, an attempt has been made to add a partial washing device capable of partially washing the laundry to the washing machine. An example can be found in Japanese Patent Laid-Open No. 2-5996. The washing machine with a partial washing device described in Japanese Patent Application Laid-Open No. 2-5996 combines a cleaning rotary body having a brush body and a convex portion on the periphery with a cleaning base, and performs washing between the cleaning rotary body and the cleaning base. The washing machine is equipped with a partial washing device for brush-washing and rubbing with an object in between.

When the lid 16 is closed, the connecting means 190 enters the connected state, and then the tray 181 is opened and closed integrally with the lid 16.

The upper plate 11 is provided with locking means 200 for locking the lid 16 in the closed state. The structure of the locking means 200 is shown in FIG.
5 is shown in a partially enlarged view added in FIG. Locking means 2
00 constitutes the solenoid 201 and the solenoid 2
In order to arrange 01, the pocket portion 202 is formed in the upper plate 11 at a position corresponding to the front edge of the laundry inlet 15. The pocket portion 202 has a shape protruding upward and opening downward. A hanging piece 203 is formed on the front lid 16a so as to overlap the front surface of the pocket portion 202.

Solenoid 201 in pocket 202
And the plunger 204 is projected to the front surface of the pocket portion 202. The hanging piece 203 is formed with a hole 205 for engaging the plunger 204. With the lid 16 closed, the controller 20 controls the solenoid 20.
When 1 is excited and the plunger 204 projects and engages the hole 205, the lid 16 cannot be opened. The excitation of the solenoid 201 is released, and the plunger 20
When 4 is displaced to the retracted position and disengaged from the hole 205, the lid 16 can be opened. It should be noted that the upper surface plate 11 is provided with a concave portion 11a for facilitating finger placement on the front edge of the front lid 16a.
Is formed.

The top plate 11 is also 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 detection means 210. The switch 211 arranged near the center of rotation of the rear lid 16b and the arm 212 protruding from the rear lid 16b constitute the lid open / closed state detecting means 210. When the lid 16 is closed, the arm 212 contacts the actuator 213 of the switch 211 and moves it. This causes the switch 211 to emit a signal, which is transmitted to the control unit 80. When the lid 16 is opened, the arm 212 is separated from the actuator 213 and the switch 21
The state of 1 is switched, and a different signal is transmitted to the control unit 80.

Both the switch 211 and the arm 212 are the top plate 1.
Place below 1. Arm 212 and actuator 21
3, the arm 212 may contact 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.

After the lid 16 is opened and the connecting means 190 is disengaged, the tray 181 is supported by the shaft 182 and the telescopic legs 220 shown in FIG. The telescopic legs 220 include a case 221 fixed to the lower surface of the tray 181 and a case 2
A pin 22 slidably supported in a vertical direction 21
2 and the pin 222 are urged downward so that the lower end of the pin is case 2
The compression coil spring 223 is made to project from the lower surface of 21. These telescopic legs 2 are provided on the left and right ends of the tray 181.
The tray 181 is supported by attaching 20 and hitting the tip of the pin 222 with the top plate 11. When pressure is applied to the tray 181 from above, the compression coil spring 223 contracts according to the pressure, and the tray 181 sinks by that amount.
In other words, the distance between the tray 181 and the partial washing device 100 is increased.

Although the tray 181 tries to approach the partial washing device 100 due to the elastic force of the compression coil spring 223, the tray 181 does not approach a certain distance or more due to the function of the distance maintaining means 230 shown in FIG. The space maintaining means 230 is provided with the protrusion 2 that rises from the rear end of the receiving portion 184 of the tray 181.
31 and a protrusion 232 that hangs down from the lower surface of the case 101 of the partial washing device 100 so as to face it. The tray 181 can be rotated until the protrusion 231 and the protrusion 232 come into contact with each other.
4 and the tray 181 are slightly separated from each other.

The distance between the washing section 110 and the tray 181 is monitored by the distance detecting means 240. Interval detection means 24
0 is a switch 2 fixed to the lower surface of the top plate 11 so as to be vertically aligned with one of the left and right telescopic legs 220.
41. The switch 241 is provided with a rod-shaped actuator 242 which moves linearly up and down, and three contacts 243a, 243b, and 243c arranged vertically. The actuator 242 acts on the central contact 243b. The signal from the interval detecting means 240 is supplied to the control unit 8
Sent to 0.

On the upper surface of the pedestal portion 184 of the tray 181, a U-shaped protrusion 250 in a plan view is formed. The protrusion 250 has a shape that surrounds the washing section 110 from the front side and the left and right sides. The reason why one side is opened without surrounding from four sides is to allow the cleaning liquid to flow out from there.
The protrusion 250 is provided to prevent the fingers from approaching the washing unit 110, and the laundry must be passed over it, so the protrusion 250 is not too high.

The right front side upper surface of the upper surface plate 11 is the operation panel 9
It is 0 (see FIGS. 2 to 5). The configuration of the operation panel 90 is shown in FIG. Reference numeral 511 denotes a course display unit for displaying the contents of the driving course and various guidances, and 512 denotes a detergent amount display unit for displaying a detergent amount suitable for the amount of water used, and these are display devices such as a liquid crystal panel. In addition, the operation panel 90 includes various operation keys. Here "key"
Is used as a representative name of a finger input interface, and the meaning is not limited to a typical key found in a keyboard of a personal computer or the like. In the illustrated embodiment, the push button portion of the membrane switch is a "key". C with touch panel
When the operation panel is configured by the RT or the liquid crystal display, the button icon on the screen is a “key”.

The operation panel 90 has the following operation keys. Reference numeral 513 is a power key for controlling the power supply to both the main body 2 and the partial washing device 100, which is turned on when pressed once and turned off when pressed again. A partial washing key 514 is used to start the operation of the partial washing apparatus 100. That is, the partial washing key 514 serves as a start key for the partial washing device 100. Adjacent to the partial wash key 514,
Selection confirmation lamp 51 indicating that partial washing has been selected
4a is provided. The selection confirmation lamp 514a is composed of an LED.

Reference numeral 515 is a start key used to start the operation of the main body 2, 516 is a course selection key for selecting a driving course, 517 is a dehydration key for changing the dehydration time, 51
Reference numeral 8 is a rinse key for changing the number of rinses, 519 is a wash key for changing the wash time, and 520 is a water level key for setting the water level inside the washing tub 30. 521 is a rewashing key for selecting a driving course different from the normal driving course selected by the course selection key 516, and selection confirmation lamps 521a and 521b are provided adjacent to the rewashing key. The selection confirmation lamps 521a and 521b are also composed of LEDs. Reference numeral 522 is a reservation key for performing reserved operation.

Next, the operation of the washing machine 1 with the partial washing device will be described.

The partial washing device 100 is placed at the storage position and the lid 16 is opened. When the laundry is put into the washing tub 30 through the laundry input port 15, the lid 16 is closed, and the operation key of the operation panel 90 is operated to select the operation course, the automatic operation of the washing machine 1 with the partial washing device is started. Be started. First, the amount of laundry is determined, and then water is supplied to the washing tub 30. 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 supply valve 50 is closed when the water level switch 55 detects that the amount of water corresponding to the amount of laundry has been poured into the washing tub 30. At this time, the water in the washing tub 30 is a washing liquid in which the detergent is dissolved due to the detergent being added after the water supply or during the water supply process.

Subsequently, the washing process is started. In the washing process, the motor 41 rotates the pulsator 33, and the rotation of the pulsator 33 stirs the washing liquid to wash the laundry. At this time, the dehydration 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 are moved. After a lapse of a predetermined time, the motor 41 stops, the pulsator 33 stops rotating, and the washing process ends. Subsequently, the rinsing process is started. The drain valve 66 opens, and the washing liquid in the washing tub 30 is drained through the drain space 64. When the predetermined time has passed and most of the washing liquid has drained from the laundry, the clutch device 42 switches,
The motor 41 in turn rotates the dehydration shaft 44. As a result, the washing tub 30 spins at 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 gathers on the inner surface of the peripheral wall of the washing tub 30, but as described above, since the washing tub 30 spreads upward in a tapered shape, the washing liquid that has been subjected to the centrifugal force is not washed. Ascend inside. The washing liquid is discharged from the water discharge port 31 when it reaches the upper end of the washing tub 30. The washing liquid that has left the water outlet 31 is struck on the inner surface of the water tub 20, travels along the inner surface of the water tub 20, and flows down to the bottom of the water tub 20. Then, it is discharged to the outside of the main body 2 through the branch pipe 60a and the drainage hose 60 that follows it.

After the laundry is thoroughly dehydrated, the drain valve 66 is closed, and rinse water is supplied this time. When a predetermined amount of rinsing water is accumulated in the washing tub 30, the pulsator 33 is rotated to stir the rinsing water, and the dirt and detergent components remaining in the laundry are dissolved in the rinsing water. After the lapse of a predetermined time, the pulsator 33 is stopped and the drain valve 66 is opened to drain the rinse water. Then, the washing tub 30 is rotated for dehydration, and the rinse water is shaken off from the laundry. Such rinsing and dehydrating operations are repeated a predetermined number of times to complete the rinsing step. Subsequently, the dehydration process is started, and finish dehydration is performed for a predetermined time to complete all the washing processes.

In the above description, "rinsing and rinsing" is performed in which the rinse water is stored in the washing tub 30 for rinsing. However, while the washing tub 30 is rotated at a low speed, water is poured from the water supply nozzle "shower pouring". Sometimes. Which one to use, or both to use, is determined by the laundry course and the amount of laundry.

Next, the function of the operation keys on the operation panel 90 will be described.

When the power key 513 is turned on and the start key 515 is pressed once, the operation of the main body 2 starts. Press again to pause driving, press again to resume driving.

When the power key 513 is first turned on,
In the course display portion 511, the display of “standard course” as shown in FIG. 20 appears by default. As illustrated in FIG. 20, the “standard course” has process contents such as “washing 10 minutes, rinsing twice, dehydration 6 minutes”.

By pressing the course selection key 516, the driving course can be changed. In addition to the "standard course", driving courses such as "mud course", "wool course", "blanket course", "dry course" and "put-on-wash course" are available.

The operation course is composed of "washing step → rinsing step → dehydration step", the washing step is a process element of "load detection → water supply → stirring", and the rinsing step is "drainage → rinse dewatering → water supply → stirring". Element and dehydration process is "Drainage → Finish dehydration"
Each of the process elements is included. Then, as shown in FIG. 21, a driving chart for each driving course is set.

For example, in the "standard course", a washing process consisting of load (laundry amount) detection of 0.2 minutes, water supply of 3 minutes and agitation of 10 minutes, drainage of 2 minutes, rinsing and dehydration of 3 minutes, water supply of 3 minutes and agitation of 5 minutes.
Rinse process that repeats 2 times, drainage 2 minutes, finish dehydration 6
A dewatering process consisting of minutes is programmed. The numbers in the "Water supply" and "Drainage" columns in the table are enclosed in parentheses.
This number changes depending on the amount of water.

After selecting the driving course with the course selection key 516, the dehydration key 517 and the rinsing key 51 are used as necessary.
8. Press the wash key 519 and water level key 520 to correct the water level and operation chart.

First, the dehydration key 517. If the dehydration key 517 is pressed once while the "standard course" is displayed as shown in Fig. 20, the display of "6 minutes" becomes "3 minutes", and at the same time the display of "standard course""wash""rinse" Disappear. When the start key 515 is pressed in this state, the dehydration operation for 3 minutes is performed. When the dehydration key 517 is pressed again without pressing the start key 515, "3 minutes" becomes "1 minute", and when it is pressed again, the display on the course display portion 511 disappears. When you press it again, "6 minutes" is displayed again.

A rinse key 518 is next. When the rinse key 518 is pressed after changing the dehydration time with the dehydration key 517, the number of rinses is changed while the changed dehydration time is displayed. When the rinse key 518 is pressed once, "rinse twice" is displayed, when it is pressed again, "rinse once" is displayed, and when it is pressed again, the display on the course display portion 511 disappears. When you press it again, "Twice rinse" is displayed again.

Then, the wash key 519 is pressed. Dehydration key 5
When the dehydration time is changed with 17, and the rinse key 518 is used to change the rinse number and then the wash key 519 is pressed, the wash time is changed while displaying the changed dehydration time and the changed rinse number. When the wash key 519 is pressed once, "Wash 10 minutes" is displayed, when it is pressed again, "Wash 8 minutes" is displayed, when it is pressed again, "Wash 3 minutes" is displayed, and when it is pressed again, the display on the course display section 511 is displayed. Disappears. When the wash key 519 is pressed again, "wash 10 minutes" is displayed again.

There is no priority among the dehydration key 517, the rinse key 518, and the wash key 519. Start key 515
The setting can be changed by pressing any of these three keys until the operation of the main body 2 is started by pressing.

Finally, the water level. For the water level inside the normal washing tub 30, turn on the power of the main body 2 and start key 515.
Is turned on to start the operation, the amount of laundry is detected and automatically determined, and the water level key 520 is used when it is desired to change this.

At the start of use of the washing machine 1 with the partial washing device,
The water amount is not displayed on the course display portion 511 only by pressing the power key 513. The detergent amount display portion 512 does not display the detergent amount display. When the amount of laundry existing in the washing tub 30 is measured, a water amount corresponding to the measured amount is automatically set, and the set water amount is displayed on the course display portion 511.
Further, the amount of detergent suitable for the amount of water is displayed on the detergent amount display portion 512.

When the water level key 520 is pressed once, "60 L of water" is selected and displayed. When the pressing is repeated, "40 L of water" and "20 L of water" are sequentially selected and displayed. After "20L of water", "wait for automatic determination"
The water amount display disappears from the course display unit 511. “Waiting for automatic determination” is a state of waiting for the process from detecting the amount of laundry to automatically determining the amount of water. When the water level key 520 is pressed again in this state, "water volume 60 L" is displayed again.

As the amount of water is set as described above, the display on the detergent amount display section 512 also changes. When the amount of water is 60 L, the color or lightness changes to the uppermost stage of the display section that imitates a measuring cup (the change in color or lightness is represented by a basket pattern in FIG. 15). "Water volume 40L" is 2/3 from the bottom
Up to 1/3 from the bottom for "20 L of water", to a height commensurate with the amount of water automatically determined for "automatic determination",
The color or brightness changes.

In this way, after selecting a driving course with the course selection key 516 and changing the driving chart and the water amount setting using the dehydration key 517, the rinse key 518, the wash key 519, and the water level key 520 as necessary, the start is started. Key 515
When is pressed, the operation of the main body 2 is started with the content displayed on the course display portion 511. During operation, the washing key 519 lights up or blinks while the washing process is in progress, the rinsing key 518 while the rinsing process is in progress, and the dehydration key 517 while the dehydration process is in progress, respectively. Alternatively, the color is changed to indicate which process is currently in progress.

If a stain that cannot be handled by ordinary washing is found in advance, the partial washing device 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 stored position is transmitted from the position detection device 170 to the control circuit unit 138 or the control unit 80 that controls the control circuit unit 138, and the partial washing device 100 is operated. This is because it is in a prohibited state. Therefore, first, the locking means 16
It is necessary to release 0 and rotate the partial washing device 100 by 90 ° in the horizontal plane to displace it to the position for use.

The partial washing apparatus 100 is rotated with the lid 16 closed. This is because, when the lid 16 is opened, 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 washing device 100 is rotated from the stored 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 reengages to lock the partial washing device 100 in its position.

Next, the lid 16 is opened. When the lid 16 is lifted, the tray 181 is also lifted by the connecting means 190.
The tray 181 that has been lifted hits the partial washing device 100. The partial washing device 100 performs the displacement by a displacement mode other than the rotation in the vertical plane, in this case, the rotation in the horizontal plane, and the tray 181 cannot lift the partial washing device 100. Therefore, when the tray 181 hits the partial washing device 100, the tray 181 is prevented from following the lid 16, and the connecting means 190 is disengaged.
Although the lid 16 continues to rotate, the tray 181 remains under the partial washing device 100. The tray 181 left behind is supported on the top plate 11 by the telescopic legs 220 as described above.

When the lid 16 is completely opened, it is folded in half. Even in this case, as described above, the front lid 16
The a does not come into contact with the partial washing device 100. In the situation where an obstacle is approaching the top of the main body 2 as shown in FIG. 1, the lid 16 is opened while the form conversion into two folds is being advanced.

The locking means 200 originally locks the lid 16 in the closed state in order to prevent the hands, etc. from touching the washing tub 30, the pulsator 33, and the laundry in the washing process and the dehydrating process. Can also be used. That is, the lid 16 can be opened and closed without interfering with the partial washing device 100 when the partial washing device 100 is in the storage position or the use position. However, when the partial washing device 100 is in another angular position, the lid 16 and the partial washing device 100 may interfere with each other depending on the angle.

Therefore, it is assumed that the position detecting means 170 detects whether the partial washing device 100 is in the stored position or in the used position. This can be easily achieved by adding another actuator actuating protrusion 173. The partial washing device 100 is located between the stored position and the used position, and the position detection means 170 is provided.
When the lid 16 does not emit a signal, it is judged that there is a risk of interference if the lid 16 is opened, and the lid 16 is locked by the locking means 200. When the partial washing device 100 is displaced to the stored position or the used position and the position detection means 170 gives a signal,
The lock by the locking means 200 is released.

The lid 16 is opened by placing the partial washing apparatus 100 at the position when it is used, because if the lid 16 remains closed,
The cleaning liquid poured into the partial cleaning device 100 is the upper surface of the lid 16,
This is because it may wet the floor. Lid 16
When the lid is opened, the lid open / closed state detecting means 210 detects it, and puts the partial washing apparatus 100 into the operation startable state.

When the power key 513 is turned on, the position detecting means 170 detects that the partial washing device 100 has reached the position for use and that the lid 16 has been opened, and the control circuit section 138 and the control section 80 are detected. Send a signal to. The control unit 80 thereby switches the partial washing device 100 to the operable state. The power key 513 may be turned on after the partial washing device 100 is set at the position where it is used.

When the partial washing key 514 on the operation panel 90 is pressed when the partial washing apparatus 100 reaches the position for use, the selection confirmation lamp 514a lights up to indicate that partial washing is selected. The operating state display lamp 128 of the operation panel 125 also lights up. Along with this, the control circuit unit 1
38 operates the tray detecting means 131. The tray detection means 131 detects whether the tray 181 exists under the partial washing device 100 in a state where it can be used without being damaged or dropped. At this time, the operating state display lamp 128 is in a blinking state to notify that it is being detected.

The operation of detecting the tray 181 is performed for a predetermined short time (for example, 0.5 times after the partial washing key 514 is pressed).
~ 1 second). The reason for limiting the time is that it is necessary to quickly decide not to vibrate the vibration horn 114 because a finger may contact the vibration horn 114 if the tray 181 is damaged or dropped. is there.

When the tray detecting means 131 cannot detect the presence of the tray 181, because the tray 181 is damaged or has fallen off, the operation status display lamp 128 does not stop blinking or lights up in a different color. The user is informed of the abnormality. The partial washing device 100 cannot start the operation, and the power is turned off after a predetermined time has passed.
become.

When it is determined that the tray 181 exists in a state of being usable, the control circuit section 138 operates the ultrasonic wave transmitting circuit. The operation state display lamp 128 changes from blinking to continuous lighting, and indicates that the operation of the partial washing device 100 can be started.

When the laundry is put on the tray 181 and the strength setting key 127 on the operation panel 125 is pressed after the preparation for using the partial washing apparatus 100 is completed,
The pressed key is continuously lit to notify that the key has been selected, and the operation of the partial washing device 100 is started. For example, if you press the "strong" key, this key will light continuously,
"Strong" driving begins.

At the same time when any one of the strength setting keys 127 is selected, the valve portion 50b of the water supply valve 50 is opened and a predetermined amount of water, for example 50 to 300 cc / min, is supplied to the cleaning liquid tube 132. Water is poured from the water injection part 132a to both sides of the vibrating horn 114, and drips onto the tray 181 from the slit 123 and the cleaning liquid droplet lower hole 124.

[0100] The ultrasonic vibration device 111 starts ultrasonic vibration with the start of dropping the cleaning liquid. When this state is reached, the laundry is slowly passed through the gap between the vibration horn 114 and the pedestal 184 while applying the laundry to the tip of the vibration horn 114. Ultrasonic waves are concentrated on the laundry and the dirt components are peeled off. The separated dirt component is drained together with water.
5, it is received by the gutter 186, passes through the drain port 187 of the gutter 186, falls into the gap between the water tub 20 and the washing tub 30, and is discharged from the main body 2 through the drain hose 60.

During the operation of the partial washing apparatus 100, the operating state display lamp 128 is continuously turned on to notify the user that ultrasonic waves are being generated. In addition, the strength setting key 12
7 can be operated to switch the strength of ultrasonic cleaning.

After the operation of the partial washing apparatus 100 is started, the tray detecting means 131 restarts the detecting operation. This re-detection is performed to check whether or not the tray 181 is damaged due to the weight of the laundry or the pressure of the user's hand. If no abnormality is detected for a predetermined time (for example, 1 to 10 minutes), it is not necessary to check any more, so it is preferable to automatically turn off the power of the tray detection means 131.

Similarly, after the operation of the partial washing device 100 is started,
The laundry detection means 301 performs a detection operation. The laundry detection means 301 is set to detect an opaque body without detecting a transparent body, and the tray 181 has a transparent body 303 (see FIG. 14) at least at a position facing the laundry detection means 301.
It is composed of. When the laundry is placed on the cradle 184, the light emitted from the laundry detecting means 301 is reflected by the laundry and returns to the laundry detecting means 301. With this, it is determined that "there is laundry", and the operation of the partial washing device 100 continues.

When the laundry is not placed on the cradle 184, or when the laundry is once placed but then comes off the cradle 184, the light emitted from the laundry detecting means 301 emits the laundry. Does not return to the laundry detection means 301 without passing through the transparent portion 303 of the tray 181 without being reflected. At this time, it is determined that "there is no laundry", and the partial washing device 100 stops the operation. As a result, it is possible to avoid the risk that the head portion 116 of the vibrating horn 114 continues to vibrate without being covered by the laundry and a thin finger of an infant or the like touches it.

The presence or absence of the laundry is determined by the laundry detection means 3
Since the light emitted by 01 passes through the tray 181 or is blocked by the laundry, there is no unstable element and the partial washing device 100 does not malfunction.

When there is no change in the detection signal of the laundry detection means 301 for a predetermined period of time, the operation of the partial washing device 100 is stopped and the power is turned off. This is based on the following reasons. That is, if partial washing is actually performed, the laundry moves while contacting the vibration horn 114, so that the detection signal changes. If there is no change, it means that the laundry is left set, or the signal is constant due to some failure, and the operation is stopped to ensure safety.

As described above, before the operation of the partial washing device 100 is started, the tray detecting means 131 is operated to check the presence of the tray 181, and with the detection information that the tray 181 exists, the operation of the strength setting key 127 is ready to be accepted. Align and operate the strength setting key 127 to operate the partial washing device 100
After the operation of No. 1 is started, the laundry detection means 301 is activated to check the presence / absence of the laundry, and the operation of the partial washing device 100 is controlled with the detection information as to whether or not the laundry is present. Detection is performed in order, and control is performed to move to the next process based on the detection information.
It is possible to provide a washing machine 1 with a highly safe partial washing device by eliminating a risk that the partial washing device 100 is operated even if 81 is damaged or dropped.

In the washing machine 1 with the partial washing device, the partial washing device 100 cannot be operated simultaneously with the operation of the main body 2. This is based on the following reasons. First, the fact that the main body 2 is in operation means that the pulsator 33 is rotating during the washing or rinsing process, and the washing tub 30 is rotating during the dehydration process. Must be avoided. Even if the hand does not come into direct contact with the pulsator 33 or the washing tub 30, the weight balance inside the washing tub 30 is unbalanced, so if abnormal vibration occurs during the spin-drying rotation, the partial washing device 100 will reach the user's hand. There is a danger of hitting. Also, in a situation where water is swirling in the washing tub 30 for easy washing, if the lower end of the partially washed laundry is immersed in water, the laundry will be twisted and the partial washing device 100 or the user There is also the danger of getting caught in your hands.

Therefore, the main body 2 cannot be operated when the partial washing device 100 is pulled out to the position for use. Generally, the fully automatic washing machine is designed not to be operated with the lid open, so if the partial washing device 100 is placed at the position for use and the lid 16 is opened, the main body 2 can be opened by opening the lid 16. The prohibition of driving is confirmed.

If the main body 2 is in operation, the partial washing device 10
When 0 is set to the position for use, the main body 2 is forcibly placed in the suspended state.

On the contrary, it is possible to prevent the partial washing device 100 from being pulled out to the position for use when the main body 2 is in operation. This can be realized by providing an electromagnetic lock means at the bearing portion 104 or the support shaft portion 142.

As described above, the main body 2 and the partial washing device 100
However, an exceptional process is provided here. It is a process of supplying water to the main body 2 for washing. Since neither the washing tub 30 nor the pulsator 33 rotates during this process and there is no danger to the user, the prohibition of simultaneous operation is lifted so that partial washing can be performed at the same time.

If partial washing is performed while water is supplied to the washing tub 30, time is not wasted that much. Also,
Since the laundry that has been partially washed can be dropped into the washing tub 30 as it is and can be transferred to normal washing by the main body 2, there is no waste of operation and time can be saved.

When partial washing is performed during the period of water supply to the washing tub 30 and the water supply is completed even though the partial washing apparatus 100 is continuously operating, the main body 2 starts the washing process. Since this is dangerous, this is not allowed, and the main body 2 is forcibly placed in the suspended state.

As described above, when the partial water washing is completed first during the water supply period, or when the partial washing apparatus 100 is pulled out to the position for use, or the user When the main body 2 is in the temporary stop state due to the manual stop by pressing the start key 515, the temporary stop state is released by any of the following three factors. (A) Stopping the operation of the partial washing device 100 (b) Closing the lid 16 (c) Inputting an operation start signal of the main body 2 (start key 515
Press to cancel the pause)

The above (a) is a manifestation of a situation change in which the operation of the main body 2 can be started. In (b), it is possible to read the user's positive intention to close the lid 16 and close the lid 16 to start operation of the main body 2. (C) is also a manifestation of the user's intention to finish the partial washing and move to the operation of the main body 2. In the case of (b) and (c), the ultrasonic vibration device 1
Even if 11 is oscillating, the oscillation is forcibly terminated.
In the cases (a) and (c), the pulsator 33 and the washing tub 30 do not always start moving immediately even if the temporary stop state is released. Prerequisite safety conditions, such as closure of the lid 16, must be ensured.

The partial washing device 100 automatically turns off the power supply when a predetermined time (for example, 3 to 10 minutes) has elapsed from the start of operation.
Become F. This is the end of normal operation, and the operation status display lamp 128 is turned off at this time. When the partial washing apparatus 100 stops operating due to a factor other than the automatic stop due to the lapse of this predetermined time, for example, the partial washing apparatus 100 has moved from the position at the time of use, the lid 16 has been closed, the start key 515 has been pressed, or In the case where the ultrasonic device 111 has failed, a display in a mode different from the display indicating that the vehicle is operating is displayed to notify this. For example, the operating status display lamp 128
Blinks (the blinking in this case changes the rhythm with the blinking at the time of tray detection) or emits light of a different color to notify that an operation stop other than the normal operation end has occurred. Except when the operation is stopped due to a failure, the notification may be given only for a predetermined time.

The structure around the partial washing device 100 can be modified as follows.

The tray 181 may be supported by the upper surface plate 11 instead of by the rear lid 16b. Top plate 1
1 is formed with a bearing portion, and the shaft portion 1 of the tray 181 is attached to this bearing portion.
82 will be engaged, and in this case also, it is natural that the axes of the shaft 18 and the shaft 182 are made to coincide with each other in the movement.

When the tray 181 is damaged or dropped off, a voice warning may be given instead of the warning display by the operation status display lamp 128 or together with the warning display by the operation status display lamp 128.

Means other than the operation status display lamp 128 may be used to indicate that the partial washing device 100 is in operation. You may display it on the liquid crystal display or play a melody to notify you.

The transparent body provided at the portion of the tray 181 facing the laundry detecting means 301 does not have to be colorless and transparent, and may be a colored transparent body. In short, laundry detection means 3
All that is necessary is to recognize that 01 is a transparent body. Further, not only a part of the tray 181 is made transparent, but the entire tray 181 may be molded by a light transmitting material. Instead of the light transmitting material, it is possible to use a material that absorbs light and does not cause reflection.

A portion of the tray 181 that intersects the optical axis of the laundry detection means 301 may be a through hole. With this structure, the light transmittance decreases due to the accumulation of dirt like the light transmissive material.
Don't worry about causing recognition errors. Since this through hole also functions as a drainage hole for the cleaning liquid, the tray 18
The situation that water overflows from 1 becomes even more unlikely.

Although mere water is poured as the cleaning liquid from the water injection section 132a, it is possible to improve the cleaning effect by adding an additive such as a detergent to the water. This can be realized by providing an additive mixing section in the middle of the cleaning liquid tube 132 or connecting the cleaning liquid tube 132 to a separately provided cleaning liquid tank.

It has been explained so far that the partial washing device 100 is rotated with the lid 16 closed. This is because when the lid 16 is opened, the tip of the partial washing device 100 is moved to the lid 1 when the partial washing device 100 is rotated from the stored position to the used position or vice versa.
This is because it hits the root of 6 (the root of the rear lid 16b). However, the dimensional factors such as the width of the gate opening 180, the length of the partial washing device 100 (turning radius), and the position of the center of rotation of the partial washing device 100 are adjusted to adjust the lid 1
It is also possible to rotate the partial washing device 100 without causing interference with the lid 16 even when 6 is opened.

Further, the partial washing device 100 may be of a fixed type. That is, the washing unit 110 is attached to the main body 2
The partial washing device 100 is fixed with the shape facing the laundry inlet 15 from the outside. By doing so, the components provided along with the movable partial washing device 100, for example, the position detecting means 170 of the parts washing device 100 or the connecting means between the rear lid 16b and the tray 181. 190 can be abolished.

The distance maintaining means 230, the distance detecting means 240, and the protrusion 250 provided in association with the tray 181 function as follows.

First, with respect to the space maintaining means 230, the existence of the space maintaining means 230 prevents the tray 181 from hitting the vibrating horn 114 even when the tray 181 is lifted up together with the lid 16. Therefore, even if the ultrasonic vibration device 111 oscillates, no abnormal noise is generated from the tray 181 and the tray is not damaged by the ultrasonic vibration.

The space maintaining means 230 is not limited to the structure in which the projections are brought out from both the tray 181 and the case 101 and are brought into contact with each other. Tray 181 and case 1
The long protrusion may be formed only from one side of 01. Alternatively, a mechanism for restricting the upward rotation of the tray 181 may be provided at the shaft 182 of the tray 181.

Next is the interval detecting means 240. If nothing is placed on the tray 181, the tray 181 is supported by the telescopic legs 220 at the height shown in FIG. 17, and A ₀ is provided between the vibrating horn 114 and the pedestal portion 184 of the tray 181.
There is an interval of. Contact 2 in switch 241
43a and contact 243b are in contact.

As shown in FIG. 18, when a laundry having a thickness B is sandwiched between the vibrating horn 114 and the pedestal portion 184, the tray 181 is provided.
Slightly sinks, and the distance between the vibrating horn 114 and the pedestal portion 184 increases to A ₁ . At this time, the contact 243b becomes the contact 243.
Neither a nor contact 243c is contacted.

When the tray 181 is pushed further downward as shown in FIG. 19, the distance between the vibrating horn 114 and the pedestal portion 184 increases to A ₂ , and the contact 243b comes into contact with the contact 243c. As described above, the contact state of the contact of the switch 241 varies depending on the width of the washing unit 110 and the receiving unit 184 of the tray 181, and a different detection signal is transmitted to the control unit 80. 100 is controlled as follows.

First, when the distance between the vibrating horn 114 and the pedestal portion 184 is A ₀ as shown in FIG. 17, the vibrating horn 114 is used.
It is determined that the laundry is not inserted between the pedestal portion 184 and the cradle portion 184, and the operation of the partial washing device 100 is stopped. That is, the ultrasonic vibration device 111 is not oscillated and the cleaning liquid is not flowed.

As shown in FIG. 18, when the distance between the vibrating horn 114 and the pedestal portion 184 increases to A ₁ , the vibrating horn 11
4 and the cradle section 184 are judged to have inserted the laundry, and the partial washing apparatus 100 is operated. That is, the cleaning liquid is caused to flow and the ultrasonic vibration device 111 is oscillated.

As shown in FIG. 19, when the distance between the vibrating horn 114 and the pedestal 184 increases to A ₂ , the vibrating horn 11
4 and the cradle part 184 are inserted into the vibration horn 1
It is determined that there is a danger of contact with 14, and the operation of the partial washing device 100 is stopped.

By performing the above control, power and water can be saved when the laundry is not inserted, and the washing unit 1 can be used.
It is possible to ensure safety when the space between the tray 10 and the tray 181 is opened.

However, it may be inconvenient for the user to perform such control.

For example, in an extremely thin laundry, the space between the vibrating horn 114 and the cradle 184 may not be so wide even if it is inserted. In such a case, the partial washing device 100
It's a problem if he doesn't start driving.

For heavy laundry such as denim,
When inserted, the distance between the vibrating horn 114 and the pedestal portion 184 may increase to about A _{2 in} FIG. Even in such a case, it would be a problem if the partial washing device 100 stopped.

Therefore, the control based on the detection signal from the interval detecting means 240 can be artificially invalidated in preparation for partially washing thin or thick laundry.

A means for that purpose is a release key 129 provided on the operation panel 125. When this is pressed, the interval detection means 2
The control performed based on the detection signal from 40 is released. That is, only the action of pressing the partial washing key 514 keeps the effectiveness, and the ultrasonic vibration device 111 is the tray 18
Oscillation is continued regardless of the ups and downs of 1. The cleaning solution also continues to flow.

By the way, invalidating the control based on the detection signal from the interval detecting means 240 as described above is essentially dangerous and cannot be continued forever. Therefore, invalidation shall be canceled by either of the following two factors. (A) Elapse of a predetermined time (b) Approach between the washing section 110 and the tray 181 within a certain distance

The above-mentioned (a) is intended to secure the safety by limiting the time when it can be invalidated. To continue the invalidation, press the release key 129 again. (B) is a story when a heavy laundry is inserted, and the vibration horn 1
14 and the cradle 184 are spaced from A ₂ to A ₁ or A _0.
When it is determined that the heavy laundry has been pulled out, the normal control based on the detection signal from the interval detecting means 240 is resumed.

The detection by the interval detecting means 240 may be confirmed when the detection signal is continuously oscillated for a predetermined time (several seconds). Thereby, malfunction due to chattering or the like can be prevented.

Next is the protrusion 250. As described above, the gap between the washing section 110 and the pedestal section 184 is set to a value of 5 to 13 mm. Therefore, the adult's fingers cannot easily enter the laundry but the ultrasonic horn 11 vibrates ultrasonically.
The risk of an adult's finger touching 4 is small. However, since the infant's finger has a high risk of touching the vibrating horn 114, the protrusion 250 is provided to obstruct the approach of the finger to the washing section 110 to improve safety.

The protrusion 250 may be provided on the upper member, for example, around the horn cover 120, but on the tray 181 which is the lower member, and the washing section 1 may be provided.
The following effects can be obtained by providing them so as to surround 10. That is, when the laundry is placed on the protrusions 250 existing so as to sandwich the washing section 110, the laundry is taut and is tightly attached to the vibration horn 114. As a result, the transmission loss of ultrasonic waves is reduced, and ultrasonic energy can be effectively used for removing dirt. Further, since a gap is formed under the laundry, the cleaning liquid can be well drained and the dirt component can be discharged smoothly.

Next, the function of the rewash key 521 will be described.

The rewashing key 521 is for selecting a special operation course different from the normal washing operation course selected by the course selection key 516. As a special operation course, "detergent saving course" and "water washing course" are prepared. Since the special operation course is set to wash the laundry that has been washed once in some way, the name "rewash" is attached to the key 521.

When the rewashing key 521 is first pressed, the "detergent saving course" is selected and the selection confirmation lamp 521a is turned on. When the rewash key 521 is pressed again, the "washing course" is selected and the selection confirmation lamp 521b is turned on.
When the start key 515 is pressed with the "detergent saving course" or the "washing course" selected, the operation according to the course starts.

The "detergent saving course" is for the partial washing device 100.
This course is designed for laundry from which dirt on the other side has been removed or laundry with a light degree of dirt, and it is decided that a smaller amount of detergent (for example, 1/2 of normal detergent) can be used. The display of the detergent amount display portion 512 is also adjusted accordingly. In designing the operation chart of the "detergent-saving course", for example, "wash 5 minutes, rinse 1 time, dehydration 3 minutes" or the like is used.

The "water-washing course" is a course in which laundry that uses the partial washing apparatus 100 or is washed by hand, or laundry that only needs to be washed with water is assumed, and no detergent is used. Therefore, the detergent cup of the detergent amount display portion 512 is also displayed in the form of "empty". In designing the operation chart for the "washing course", for example, "wash 15 minutes, no rinse,
Dehydration 3 minutes "and so on. Although the action of stirring water without a detergent can be interpreted as a kind of rinse, it is referred to as "washing with water" here in distinction from a rinse that is combined with a normal wash using a detergent. Also, "No wash, rinse once,
Dehydration 3 minutes "may be used.

It is preferable from the viewpoint of resource saving that after the partial washing of the heavily soiled portion is completed by using the partial washing apparatus 100, the operation course is changed to the special operation course instead of the operation course for normal washing. . Therefore, in order to use the partial washing device 100 and the special driving course as much as possible, a mechanism is provided to positively direct the user's consciousness toward the special driving course.

Specifically, when the partial washing device 100 is operated, a message recommending that a special operation course, that is, a "detergent saving course" or a "water washing course" is next displayed is displayed on the course display portion 511. To do. In addition, during operation of the partial washing device 100, or the partial washing device 100
For a predetermined time even after the operation of is stopped, the selection confirmation lamps 521a and 521b are alternately blinked or blinked at a special rhythm to draw the user's attention. Selection confirmation lamp 5
You may change the display color of 21a and 521b from usual, and may make it easier to notice.

Here, the overall flow of the operation of the washing machine with a partial washing device 1 will be described with reference to FIG.

In step S401, the laundry is put in the washing tub 30 and the power key 513 is pressed. Then the course display section 5
The content of the standard course is displayed at 11. Subsequently, the washing condition is selected in step S402. That is, the course selection key 516, the dehydration key 517, the rinse key 518, the wash key 519, and the water level key 520 are used to select a driving course and adjust the contents. If the standard course displayed on the course display section 511 is the same as it is, there is no need to do anything.

After selecting the driving course and adjusting the contents,
In step S403, the start key 515 is pressed. Then, the laundry weight is detected in step 404, the amount of water suitable for the laundry amount is determined in step S405, and the detergent amount commensurate with the laundry amount is displayed on the detergent amount display portion. Then, in step S406, the washing machine 1 with the partial washing device is in a suspended state.

The user applies the indicated amount of detergent to the washing tub 30.
Alternatively, the water is put into a mixing device provided in the flow path, and the start key 515 is pressed in step S407. Then, in step S408, the water supply to the washing tub 30 is started. If the water level has been set by the water level key 520 in step S402, it is not necessary to determine the water amount based on the amount of laundry, so the laundry weight detection in step S404 is omitted, and the temporary stop in step S406 is not performed, and step S408 is performed. Proceed to water supply.

When the water level determined by the amount of laundry or the water level set by the user is reached, the water supply is stopped and step S
At 409, it is confirmed whether the partial washing device 100 is operating. If the partial washing device 100 is operating, the process proceeds to step S413, and the operation of the main body 2 is temporarily stopped until the partial washing device 100 is stopped in step S414.

When the partial washing device 100 is not operated or is stopped even if it is operated, the pulsator 33 starts rotating in step S410. The pulsator 33 rotates at a predetermined speed, direction and interval according to the operation chart to stir the washing liquid and the laundry. Even when the partial washing device 100 is in operation, the start key 515 is pressed and the partial washing device 100 is pressed.
From the operation of the main body 2 or the lid 16
When the operation of the partial washing device 100 is stopped by closing, for example, the stirring in step S410 is executed.

After stirring for a predetermined time in step S410, the end of the washing process is notified in step S411, and the power is turned off in step S412 to complete the washing process.

When the automatic continuous operation from the washing process to the rinsing process is selected, after the stirring in step S410 is completed, the process proceeds to step S425 of the rinsing process.

In step S425, the drain valve 66 is opened to drain the water. When the water level switch 55 detects the completion of drainage, the washing tub 33 is rotated in step S426 to perform rinsing and dehydration. When a predetermined time has passed, the drain valve 66 closes,
In step S427, rinse water is supplied up to a predetermined water level. Next, in step S428, the pulsator rotates at a predetermined speed, direction and interval according to the operation chart to stir the laundry and dissolve the detergent in the laundry into the rinse water. After a lapse of a predetermined time, the process returns to step S425, and drainage, rinsing and dehydration, water supply, and stirring are performed again.
This is repeated the number of times specified in the operation chart.

When the automatic continuous operation from the rinsing process to the dehydration process is selected, after step S428 ends, the process proceeds to step S445 of the dehydration process.

In step S445, the drain valve 66 is opened to drain the water. When the water level switch 55 detects the completion of drainage, the washing tub 33 is rotated in step S446, and finish dehydration is performed. After finishing dehydration for a predetermined time, the end of the dehydration process is notified in step S447, and step S4
At 48, the power is turned off and the dehydration process ends.

When the operation is started from the rinsing step, the power source key 513 is pressed in step S421, and the contents of the standard course are displayed on the course display portion 511. Subsequently, the washing condition is selected in step S422. That is, using the course selection key 516, the dehydration key 517, the rinse key 518, the wash key 519, and the water level key 520, the condition of starting the operation from the rinse step is selected, and then the start key 515 is pressed in step S423.

When the operation is started from the rinsing step, the laundry weight is not detected. And the course display section 511
Since the maximum amount of water is displayed in, the appropriate water amount is selected using the water level switch 520 when the amount of water is too large.

When the start key 515 is pressed again, it is confirmed in step S424 whether the partial washing device 100 is operating. If the partial washing device 100 is operating, the process proceeds to step S431, and the partial washing device 10
0 is displayed on the course display unit 511 and the operation of the main body 2 is not accepted until the partial washing device 100 is stopped in step S432.

If the partial washing apparatus 100 is not in operation, or if it is in operation, even if it is in operation, the water is once drained in step S425. Then, the process proceeds to rinse dehydration in step S426, and thereafter, a predetermined rinse process is executed according to the operation chart.

When the operation is started from the dehydration process, the power source key 513 is pressed in step S441 to display the course display section 5
The content of the standard course is displayed at 11. Subsequently, the washing condition is selected in step S442. That is, using the course selection key 516, the dehydration key 517, the rinse key 518, the wash key 519, and the water level key 520, the condition of starting the operation from the dehydration process is selected, and then step S4.
At 43, press the start key 515.

When the start key 515 is pressed, it is checked in step S444 whether the partial washing device 100 is operating. If the partial washing device 100 is operating, the process proceeds to step S449, where the partial washing device 10
0 is displayed on the course display unit 511 and the operation of the main body 2 is not accepted until the partial washing device 100 is stopped in step S441.

If the partial washing device 100 is not in operation, or if it is in operation, it is drained in step S445. Then, the steps after step S446 are sequentially executed.

In the "detergent-saving course", only a small amount (for example, 1/2 of the usual detergent) is used, so that the washing time and the rinsing time are shorter than those in the normal washing. The operation flow is the same as the normal flow shown in FIG. The stirring time (step S410) in the washing process is shortened. Further, the stirring time (step S428) in the rinsing process is shortened, and the process from step S428 to step S425 is not repeated, and the rinsing is performed only once and the process proceeds to the dehydration process.

In the "water washing course", after the water washing step, the rinsing step is not performed and the dehydration step is executed to end the operation. The operation flow of the washing process is the same as the normal flow. In step S404, the weight of the laundry is detected to determine the water level, and the process proceeds to stirring in step S410 without displaying the detergent amount. Since it is washed only with water without using a detergent, the stirring time is set longer than usual. Since no detergent is used, rinsing is not required, and immediately after the stirring is finished, the dehydration process is performed in step S445.
Proceed to and drain the water. Then, the steps after step S446 are sequentially executed.

Although one embodiment of the present invention has been described above, the scope of the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. .

[0175]

The present invention has the following effects.

According to the present invention, in a washing machine with a partial washing device in which a main body is equipped with a partial washing device for performing a washing process according to a predetermined operation course, a normal operation course having an operation chart for normal washing, and a washing machine other than normal washing are provided.
