Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing machine operating device equipped with a rapid feed mechanism that rotates the time axis of a timer at a higher speed than the normal speed.

Conventionally, for example, in a fully automatic washing machine, a part of a series of processes from washing to dehydration using a timer is controlled by a plurality of push-button selection switches and the time axis of the timer is set to normal. A so-called program that works in conjunction with a rapid-feeding mechanism that rotates at a higher speed than the machine speed, thereby shortening washing time, reducing the number of rinses, etc., and making it possible to select multiple program courses. Unlike normal fully automatic washing machines, there is no need to set the timer by directly turning the timer axis using the operating knob, and instead it is possible to set the timer by pressing the selection switch button. It has the advantage of being able to execute a desired program course simply by selectively pressing down, and therefore the time axis of the timer shows the progress of the process instead of the operation knob for direct rotational operation. A pointer is attached. However, in general, in a washing machine, it is preferable to select the time of the washing process, that is, the detergent washing time, as desired so as to be the optimal time depending on the type, amount, and degree of soiling of the laundry. Unlike normal fully automatic washing machines, it is not possible to select and set the washing process time as desired by rotating the time axis using the operating knob, but instead of selecting and setting the desired wash process time. The degree of freedom in selection is limited because the user has to select from among the following, and therefore, even in a timer that does not have an operating knob for rotating the time axis than in the past, the washing process time can be selected as desired. development is desired.

The present invention has been made in view of the above circumstances, and its purpose is to have a timed shaft that rotates at a predetermined speed based on the operation of a timed element, and to automatically perform washing and subsequent steps in accordance with the rotation of the timed shaft. A timer is provided, and a rotating body is provided which rotates in accordance with the rotation of the time axis of the timer and has a conductive band corresponding to the washing process, and is rotated by manual operation around the time axis of the timer. An operating lever is provided that has a contact piece that contacts any position of the conductive band of the rotating body according to the rotation angle, and the time axis is set only while the contact piece of this operating lever is in contact with the conductive band. By providing a rapid feed mechanism that rotates at a higher speed than the predetermined speed, the time for the washing process can be adjusted even if the timer is not provided with an operation knob for rotating the timer shaft. The purpose of the present invention is to provide a washing machine operating device that can be selected as desired.

(27 seconds) between contact pieces (c-a), (c-b) alternately.
It is beginning to close the gap. 37 is relay 3
8 and a fast-feeding motor 39. When the fast-feeding motor 39 is energized, it rotates the timer shaft 3 of the timer 1 at a higher speed than the normal speed, thereby causing the timer 1 to operate. It is now working as a fast feed. The relay 38 is equipped with an excitation coil 38a and a switch-type relay switch 38b having a movable contact piece c and fixed contact pieces a and b.

4. Cam switches 35 and 36 for skipping strokes, selection switch 40 for rinsing, selection switch 41 for dehydration
and start push button switch 42 as shown in FIG.

Next, the operation of this embodiment having the above configuration will be explained with reference to the time chart of FIG. 3. In FIG. 3, the shaded area is the closing period. and,
When timer 1 is in the "off" stroke, its pointer 6
The central position of the "off" stroke area, that is, the boundary position between the "A" area and the "B" area of the "off" stroke, is indicated by the stroke cam switches 29 to 32, the wash speed feed cam switch 34, and the stroke omission. The cam switches 35 and 36 are in the open and closed state shown in region "B" of the "off" stroke.

(a) When the contacts (da) of the rinsing selection switch 40 and the dehydration selection switch 41 are both closed.

The operating lever 12 is manually rotated in the direction of arrow 5 or counter-arrow 5 via the knob 13, and the pointer 14 is moved to a desired time position in the "wash" stroke area on the stroke display board 7, for example, "9".
When the movable contact piece 1 is selected and set according to the position of the operating lever 12, the movable contact piece 1
6 comes into contact with an arbitrary position of the fast-feeding conductive band 9 of the rotating body 8, for example, a position corresponding to the position of "9", and the washing time setting switch 18 is closed.
Then, when the start push button switch 42 is closed for a short period of time, at this time, the contact piece (c-b) of the stroke cam switch 29 is closed and the wash speed feed cam switch 34 is closed. Contact piece of stroke cam switch 29 (c-b)
time, start push button switch 42, wash time setting switch 18, and wash speed feed cam switch 3
The excitation coil 38a and the fast feed motor 39 are energized via the motor 4. When the excitation coil 38a is energized, the relay 38 is activated and the relay switch 3 is activated.
Open the contact piece (c-b) of 8b and open the contact piece (c-b).
a) Since the gap is closed, the relay switch 38
The energizing circuit of the water supply solenoid valve 5, drain solenoid valve 23, drive motor 24, and timer motor 4, which are loads, is cut off by opening between the contacts (c and b) of the relay switch 38b. c-
A self-holding circuit of the relay 38 is formed by closing between a). Further, when the fast feed motor 39 is energized, the timer shaft 3 of the timer 1 is rotated in the direction of the arrow 5 at a higher speed than the normal speed, and the timer 1 performs fast feed in the "B" region in the "off" stroke. As a result, the pointer 6 and the rotating body 8 are also rotated at high speed in the direction of the arrow 5. Thereafter, when the pointer 6 reaches the position of "11" which is the maximum time in the "washing" stroke area, that is, the start position of the "washing" stroke, the timer 1 will shift to the "washing" stroke, but at this time the washing time Since the setting switch 18 is closed, the excitation coil 38a and the fast feed motor 39 continue to be energized, and the fast feed of the timer 1 continues. And guideline 6
However, when the pointer 14 of the operation lever 12 reaches the "9" position of the "Washing" stroke area on the stroke display plate 7, the movable contact piece 16 comes off from the fast-feeding conductive band 9 of the rotating body 8, and the washing time ends. The construction switch 18 is now open, and the excitation coil 38a
and the fast feed motor 39 is cut off, and the timer 1
At the same time, the relay 38 returns and the contact piece (c-
a) Open the gap and close the contact piece (c-b). Therefore, when the pointer 14 of the operating lever 12 is selectively set to the "9" position in the "Wash" stroke area of the stroke display board 7, the "B" zone in the "Off" stroke of the timer 1 is the fast feed. In addition, the 2-minute region of the "washing" process having a maximum time of 11 minutes is fast-forwarded and omitted, and as a result, the washing time of the "washing" process of timer 1 is set to 9 minutes. Similarly, if the pointer 14 of the operating lever 12 is set to any time position up to the maximum of "11" minutes in the "washing" stroke area on the stroke display board 7, the "washing" stroke time of the timer 1 can be adjusted. can be set at any time. When the relay 38 is restored and the contact piece (c-b) of the relay switch 38b is closed, the "washing" process (washing with detergent) is performed for the selected and set time as described above, and then As is well known, the first "drainage", the first "dehydration", the first "rinsing", the second "draining", the second "dehydration", the second "rinse",
3rd “Drainage” and 3rd “Dehydration” (5
A first program course consisting of a series of steps (minutes) is executed.

(b) Rinse selection switch 40 contact piece (d-b)
In the case where the gap is closed and the contact piece (da) of the dewatering selection switch 41 is closed.

When the control lever 12 is rotated to select and set the time for the "washing" process, that is, the detergent washing time, as described above, and the start push button switch 42 is then closed, the "washing" time for the selected and set time is set. ” process is performed, and the process moves to the next first ``drainage'' process. At this time, the stroke omitting cam switch 36 is connected to the contact piece (c-a).
Since the stroke cam switch 2 is operated to close the
The excitation coil 38a and the rapid feed motor 39 is energized,
The relay 38 operates and opens the contacts (c-b) of the relay switch 38b, thereby cutting off the energized circuits of the loads such as the water supply solenoid valve 22, the drainage solenoid valve 23, the drive motor 24, and the timer motor 4. , the fast feed motor 39 rotates and the timer 1
The timing operation is now fast forwarded, and the first "draining" step is omitted by the fast forwarding. Therefore, the contact piece (e) of the cam switch 36 for stroke omission
-a) is also closed during the first "dehydration" and first "rinsing" steps, so the first "dehydration" and first "rinsing" steps are also closed. is omitted by rapid traverse. The subsequent operation is the same as in the case of item (a) above. Therefore, in this case, the second program course, in which one rinse is omitted, will be executed.

(c) Rinse selection switch 40 contact piece (d-c)
In the case where the gap is closed and the contact piece (da) of the dewatering selection switch 41 is closed.

When the start push button switch 42 is closed after selecting and setting the desired detergent washing time using the operating lever 12 in the same manner as described above, the "washing" process for the selected and set time is carried out, and the next first wash cycle is started. Move on to the "drainage" process. At this time, the cam switch 35 for stroke omission operates to close the contact piece (c-a) between the contact piece (ca) of the stroke cam switch 29, and the contact piece (c-a) of the cam switch 35 for stroke omission. a) The excitation coil 38a and the fast feed motor 39 are energized through the contacts (c and d) of the rinsing selection switch 40, and the relay 38 is activated to cut off the energized circuit of the load, and the fast feed motor 39 rotates to fast-forward the timing operation of timer 1, and
Two "draining" steps are eliminated by rapid feed. Therefore, between the contacts (c and a) of the cam switch 35 for stroke omission, the first "dewatering", the first "rinsing", the second draining, the second "dewatering" and the second "dewatering" are performed. Since the two "rinsing" strokes are also closed, these strokes are similarly omitted by the rapid feed. The subsequent operation is the same as in the case of item (a) above. Therefore, in this case, the third program course, in which two rinses are omitted, is executed.

(d) Rinse selection switch 40 contact piece (da)
In the case where the gap is closed and the contact piece (db) of the dewatering selection switch 41 is closed.

After selecting and setting the detergent washing time using the operating lever 12 in the same manner as described above, when the start push button switch 42 is closed, the process from "washing" to the third "draining" is performed in the same manner as in item (a) above. The process is carried out. Then, when the timer 1 moves to the third "dewatering" stroke, the stroke omitting cam switch 36 operates to close the contact piece (c-b) of the stroke cam switch 29. a) Cam switch 36 for skipping the interval and stroke
between contact piece (c-b) and dehydration selection switch 4
The excitation coil 38 is connected between the contact pieces (b and d) of
a and the fast feed motor 39 are energized, and the relay 3
8 operates to cut off the energizing circuit of the load, and the fast feed motor 39 speeds up the timing operation of timer 1, omitting the ``4 minute'' region of the third ``dewatering'' process. After that, the "1 minute" region of the third "dehydration" step is performed.
Therefore, in this case, a fourth program course will be executed in which 4 minutes of the third "dehydration" step, which is the final dehydration step, is omitted and the remaining 1 minute is carried out.

(e) Rinse selection switch 40 contact piece (d-a)
In the case where the gap is closed and the contact piece (dc) of the dewatering selection switch 41 is closed.

When the start push button switch 42 is closed after selecting and setting the detergent washing time using the operating lever 12, the process from "washing" to the second "rinsing" is carried out in the same manner as in the above (a). It can be done. Then, when the timer 1 moves to the third "draining" stroke, the stroke omission cam switch 35 operates to close the contact piece (c-b) of the stroke cam switch 29.
a), the excitation coil 38a and the fast feed motor 39 are energized via the contact piece (c-b) of the stroke omission cam switch 35 and the contact piece (c-d) of the dewatering selection switch 41, and the relay 38 operates to cut off the energized circuit of the load, and the fast feed motor 3
9, the timing operation of the timer 1 is fast-forwarded, and the third "drainage" stroke is omitted by the fast-forwarding, and the distance between the contacts (c and b) of the cam switch 35 for stroke omission is as follows. Since it is also closed during the third "dehydration" process, this third "dehydration" process is also omitted by rapid feeding. Therefore, in this case, the fifth program course will be executed in which the third "drainage" and the third and final "dehydration" steps are omitted.

(f) Rinse selection switch 40 contact piece (d-b)
In the case where the gap is closed and the contact piece (db) of the dewatering selection switch 41 is closed.

In this case, after the "washing" process, the first "drain", the first "dehydration", and the first "drain", which correspond to the contact pieces (ca) of the cam switch 36 for skipping the process, are performed. A sixth program course in which the "4 minute" region in the third "dehydration" process, which corresponds to the "rinsing" process and between the contacts (c-b) of the process omitting cam switch 36, is omitted by rapid feeding. executed.

(g) Rinse selection switch 40 contact piece (d-b)
In the case where the gap is closed and the contact piece (dc) of the dewatering selection switch 41 is closed.

In this case, after the "washing" process is completed, the first "draining" and the first "dewatering" are performed between the contacts (ca) of the cam switch 36 for skipping the process.
The first "rinsing" stroke and the third "draining" and third "dewatering" strokes corresponding to the contact piece (c-b) of the cam switch 35 for stroke omission are omitted by rapid feeding. A seventh program course is executed.

(H) Rinse selection switch 40 contact piece (d-c)
In the case where the gap is closed and the contact piece (db) of the dewatering selection switch 41 is closed.

In this case, after the end of the "washing" process, the process from the first "draining" to the second "rinsing" corresponding to the contact piece (ca) of the cam switch 35 for skipping the process and the process An eighth program course is executed in which the "4 minute" region in the third "dewatering" process, which corresponds to the interval between the contacts (c-b) of the omission cam switch 36, is omitted by rapid forwarding.

(l) Rinse selection switch 40 contact piece (d-c)
In the case where the gap is closed and the contact piece (dc) of the dewatering selection switch 41 is closed.

In this case, after the "washing" process is completed, between the contacts (ca) of the process omitting cam switch 35,
(c-b) A ninth program course in which all the steps from the first "drainage" to the third "dehydration", that is, the steps after the "washing" step, are omitted by rapid feeding. is executed.

As described above, according to this embodiment, the rotating body 8 is fitted and fixed to the timer shaft 3 of the timer 1, and the rotating body 8
A fast-feeding conductive band 9 corresponding to the "B" region of the "cutting" stroke region and the "washing" stroke region is formed on the outer periphery of the rotating body 8, and a ring-shaped current collecting conductor 10 is formed on the front surface of the rotating body 8. A connecting conductive band 11 is formed to connect this and the rapid feed conductive band 9, and an operating lever 12 is provided around the time axis 3 so as to be rotatable by manual operation. A movable contact piece 16 that can contact any position of the rapid-feeding conductive band 9 of the rotary body 8 is attached via the support strip 15, and a fixed contact piece 16 that can contact the current collecting conductive band 10 of the rotary body 8 is attached to the rotary body 8. A contact piece 17 is provided, and the fixed contact piece 17, the movable contact piece 16, and the rotating body 8 form a wash time setting switch 18, and when the wash time setting switch 18 is closed, the timer 1 is switched to the wash speed. The timer 1 is activated by operating the rapid feed mechanism 37 in cooperation with the cam switch 34 to rotate the timer shaft 3 at a higher speed than the normal speed.
It is configured to rapidly advance the timing operation,
Therefore, the time up to the maximum time from the arbitrary time selected and set by the operation lever 12 can be omitted by fast forwarding, and thereby the operation knob that directly rotates the time axis 3 can be omitted. Even in the case of a timer 1 without a timer, the time for the "washing" process, that is, the detergent washing time can be arbitrarily selected and set.

Furthermore, according to this embodiment, the cam switches 35 and 36 for skipping the strokes of the timer 1, the rinsing selection switch 40, the dewatering selection switch 41, and the rapid feed mechanism 37 work together to change the process from the first "draining" stroke to the first. The first to ninth program courses are selected by omitting any or a part of the steps up to the three "dehydration" steps by rapid forwarding, and the selected one of the steps is omitted by rapid forwarding. Since the program course is executed after the "washing" process is completed for the time selected and set by the operating lever 12, the detergent washing time and subsequent program course can be adjusted according to the type, amount, or degree of soiling of the laundry. They can be combined to realize various washing modes, and are extremely convenient in terms of usability.

In addition, according to this embodiment, once the control lever 12 is set at a desired time, it remains set at that time until the next rotational change operation is performed, and the timer 1 goes into the "off" stroke. Since the detergent washing time is not reset when the washing time is reached, there is no need to reset the washing time when the same detergent washing time is continuously selected, which is extremely convenient.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, and can be applied not only to fully automatic washing machines, but also to automatic washing machines that perform processes such as washing, draining, and rinsing. Of course, modifications may be made as appropriate without departing from the scope of the invention.

The present invention has been described above, and the present invention is a washing machine that has an excellent effect in that the time of the washing process can be selected as desired even if the timer is not provided with an operation knob for rotating the time axis. We can provide machine operating equipment.
