Abstract

PURPOSE:To facilitate cleaning of a storing part by sending a command to a water supplying unit to supply water in the storing part with the elapse of a specified time after a control unit generates a command to throw a washing processing agent in, and thereby preventing the agent in the storing part. CONSTITUTION:After mixing operation by the rotation of a rotating blade unit 6 is started, water in a storing part 18 is all discharged in 40sec so as to start water supply. The water supplied to a water pouring port unit 23 rises in a water path 33, introduced into the part 18 again and supplied, thereby a finishing agent remaining in the part 18 is discharged together with water into a washing container 4. The water supply is continued for 5sec, and after waiting of 20sec, water supply for 15sec is carried out, and then operation of the unit 6 is stopped. By these two times of water supply operations, the finishing agent remaining in the part 18 is completely discharged in the container 4.

It is connected to 1 through the King Kaho T161 connection. This pressure filter detects all set water levels among the specified water levels (high, medium, and low).

In such a washing machine, a device was developed in 1986 that automatically added all the fabric softener and other ingredients into the washing layer (41) at a predetermined time.
It is shown in Japanese Patent Publication No. 0-50479 (D06F39102) and Japanese Patent Publication No. 1988-10680 (DO6F 39102).

That is, in the former case, the finishing agent is stored in advance by attaching it to the entire balance ring of the container, and making full use of the centrifugal force when dehydrating the finishing agent.
The finishing agent is moved between holding chambers divided within the container, and then introduced during the final cutting process.In the latter case, a storage container for the finishing agent is placed in advance in the operating section, and the cam is controlled to hold the finishing agent at a specified level. The container is moved to the loading position at the appropriate time.

(c) Problems to be solved by the invention In the former conventional example, when a highly viscous finishing agent is used, the finishing agent remains in the container and sticks, making cleaning later difficult. Although this method has a structure in which water is supplied into the container when the finishing agent is added, there is a problem in that if the finishing agent has a high viscosity, some amount remains in the container.

In view of such problems, it is an object of the present invention to provide a dehydrating washing machine so that no processing agent remains in the storage section of the laundry processing agent, thereby making cleaning the storage section easier. .

2) Means for Solving the Problems The dehydrating washing machine of the present invention supplies water into a reservoir for a laundry treatment agent, and introduces the treatment agent in the reservoir together with water into the vCFlfi. After the agent is added, water is re-supplied into the reservoir after a predetermined period of time.

In other words, by resupplying water into the storage area after adding the treatment agent,
The processing agent remaining in the reservoir is washed clean and discharged into the layer. The same reference numerals will be used for the parts, and the explanation will be omitted entirely.

The water inlet cover 1.1171 is formed in a shape that is concave from the periphery to the center and inclined at one end (37aJ). In addition, the wall thickness t1 of the water inlet cover (37) in contact with the water inlet cover (37) is set to 1W or less.These are measures for rounding to prevent freezing, as will be described later. The three sides of the water inlet cover 37) are in complete contact with the lower surface of the water inlet body, and the - end side (37a) is in close contact with the lower surface of the water inlet body.
A gap t2 is provided only in J.

? TJ operation piece (from 38j, further operation arm +41
extends along the side wall of the storage section 181, and -
(421 is a rotating arm that rotates in conjunction with the opening and closing of the lid (19), which rotates during the opening operation of the lid (191) and comes into contact with the operating arm (411VC); ) Push up from the entire bottom □ Therefore, the water inlet cover 37) resists the urging force of the self-suffling (protection @J@t), and the lower surface of the water inlet body (231) opens. At this time, Opening the lid tli means:
Since the purpose is to supply the finishing agent into the entire storage section +181,
It is necessary to rotate the water injection force bar T3 at an opening degree of "qV1" in order for the supply water to fully rise to the overflow channel Q and be introduced into the reservoir from the overflow port [351] of the water injection port body C23I. In this example, based on experiments, the opening degree
It is set more than once.

(431 is a mounting plate attached to the fixed foot part F441 formed integrally with the water supply channel C24 so as to be located on the side of the operation arm (4D(1)), and is a solenoid for injecting finishing agent. (451 is fixed, +461 is S
It is an actuation piece bent into a letter shape, and one end (46a) thereof is connected to the pivot hole 147 provided at the bottom of the mounting plate (431).
1 and is pivotally supported by the spring member (481) between it and the mounting plate (43). As a result, the actuating piece [4bl's other end (461)] is urged to rotate in the opposite direction of the arrow and comes into contact with the side surface of the operating arm (4I). Side (4
6b) is attracted by the excitation of the solenoid (451), rotates against the bias of the spring member (481), and is released from the contact state with the operating arm (4υ).

As described above, when the operating arm (4D75') is pushed up by the opening operation of the lid body σ9, the other end (46b) of the spring member (the actuating arm) Since the operation arm (4υ moves downward), even if the lid U9 is closed, the return of the operation arm (4υ) is regulated, and the water inlet cover 137 is held with the lower surface of the water inlet body open. .

In such a configuration, the user opens the lid σ91 and pours a predetermined amount of finishing agent into the reservoir f181.During the opening/closing operation of the lid 09, the user opens the water inlet cover ζ.
37) is locked in the open position. Then, when the program is started, the water supply solenoid valve Cl21 opens without a trench, and supply water is introduced into the water inlet body (231) from the inlet (281). The water falls from the lower surface of the water inlet body 031 onto the auxiliary water supply channel c24+, and the surface end (24a)
It is poured into the washing tub (・11 (dotted line state in Figure 5) -
1. In the final rinsing step, when the finishing agent input solenoid (4e) is energized, the actuating piece (46)
is attracted and the engagement between the actuating piece +41j and the operating arm (4υ is released), so the water inlet cover 37 returns to rotation under the bias of the spring 6!1, and the water inlet body C31 Close the bottom surface. When water is supplied, the water introduced into the water inlet body (23I) rises completely within the overflow channel and flows from the water inlet (351 to the storage section), since the bottom surface is closed. At this time, if the paddy field is higher than a predetermined height, the water inlet cover C371 opens at an opening degree corresponding to the paddy field against the spring ring (391). Therefore, part of the supplied water is drained out from here.Therefore, the overflow port is opened and the discharge amount is almost constant regardless of the water pressure.When water is supplied to the storage part σδ, this Finishing 4'' is dissolved in water, led out onto the water supply channel CI! 41, and supplied into the washing layer (41) from the front end (24a) of the water supply channel 241. Water that cannot be completely treated by a■ is stored in the overflowing part of the front wall of the storage section (from 22+ to the water supply channel c!
4) Derived above.

Now, such a fully automatic washing machine is controlled by a microcomputer, and hereafter this microcomputer 1471 (
The control mechanism of the washing machine (hereinafter referred to as microcomputer) will be explained based on FIG. 9.

The microcomputer (471 is CPU +481. RA
Mf49i, ROM 5111, timer (51)
, system bus (52) and input/output port (53) ~
(58) The CPU side 81 is composed of a control section (
59) and an arithmetic unit (60), the control unit (59) fetches and executes instructions, and the arithmetic unit (60) controls the control unit (59) during the instruction execution stage.
It performs all arithmetic processing such as binary addition, logical operations, increase/decrease, and comparison on data given from input devices and memory using control signals from the controller. The RAM (491) is for storing all data related to the washing machine, and the RAM (491) is for storing all data related to the washing machine.
M(50) il''i-All the means for operating the washing machine, the setting of conditions for judgment, the rules for processing various information, etc. are read in advance.

The input capo-1-(53) to (55) VC is an input key circuit (61) consisting of the various operation keys described above + a detection circuit (62) such as a water level detector and a top cover safety switch that is linked to the opening/closing of the top cover. ) - A signal from a time reservation setting circuit (63), etc., which is set in advance to automatically start washing at a time desired by the user, is input, and based on this information, the output cap-1 From (56) to (58), it can be seen that the LED drive circuit (64) composed of the ID group = process end notification or abnormality notification buzzer circuit (65) - load drive circuit (66) composed of bidirectional thyristors, etc. ), etc., a control signal is sent out. The load drive circuit (66) operates according to the control signal from the microcomputer (47I) to control the left and right rotation circuit (67H68) of the rotor blade drive motor (71), the water supply solenoid valve drive circuit (69), and the drainage solenoid valve drive circuit (70). ] and the finishing agent injection solenoid drive circuit (71). 0 (72) is a power supply circuit that supplies the microcomputer C47) VC voltage, and (73) is a reset signal generation circuit.

In this embodiment, as a water level detector replacing the above-mentioned Ohkasui Sochi σ9, a magnetic substance is moved in and out of a coil in response to changes in the water level in the washing tub 14+ to change the inductance of the coil. A water level sensor (not shown) configured to detect changes in the water level is used; in other words, the water level is detected by determining changes in the inductance of the microcomputer (47I) or the coil, so the water level in the tank is can be detected continuously.

Therefore, the fully automatic washing machine sequentially executes 10 grams of washing, rinsing, and dehydration steps under the control of the microcomputer (471). When repeating, the grain time is dehydrated. There are two methods: pre-rinsing and water pouring. I can do it.

Incidentally, rinsing refers to draining the entire water supply after supplying water to a specified water level, and rinsing with water refers to draining the entire water supply after supplying water to a specified water level.
+h It's a clove thing that rarely overflows.

Hereinafter, the finishing agent injection operation will be explained according to Figure 1O. area, if water injection rinsing, perform control a of area Y.

After the intermediate spin-drying, the microcomputer 4η first starts supplying water into the washing tub IJ for final rinsing (X-1
). Next, when water has been supplied for 10 seconds, the finishing agent input solenoid is energized +451k, and the amount of washing is 14.
A finishing agent is put into H: rinsing (x-2). When this input operation is performed for 2 seconds, the excitation of the solenoid f45) is cut off (X-3), and the water supply is started when the set water level is reached.
Move to X-5).

That is, when 40 seconds have elapsed since the stirring operation by the rotation of the rotary blade (6I starts (X-6)), water supply is started (during which time all the water in the storage part (181) is drawn out).
X7).

At this time, the previous finishing agent injection operation [jsu,
Since the lower surface of the water inlet (181v) is closed by the water inlet cover (37), the water introduced into the water inlet (181v) rises within the overflow channel and returns to the reservoir (181v).
c is introduced. In this way, by supplying water into the storage part aδ, the finishing agent remaining in the storage part (181) is transferred to the washing tub (181) together with water.
41.

This water supply is carried out for 5 seconds (X-8), and after waiting for 20 seconds, water supply is carried out again for 15 seconds (X-9) (X
-10), the rotor (6) is stopped E.

(X-11). During these two water supply operations, the finishing agent remaining in the reservoir a8 is completely drained into the washing tub 1.
Ejected within 4+.

(Water rinsing) If the final rinsing is too much, □Finish the final rinsing without adding finishing agent and start draining. (Y-13゜This drainage is done for 20 seconds, and the washing tub (4
1 VC stops with water still remaining (Y-2)
. Next, water is supplied again (Y-3), and at the same time the finishing agent input solenoid (451' is energized and the washing tub 14I
(Y4) n The finishing agent injection operation is 2.
The water supply is stopped after 50 seconds (Y-5), the water supply is stopped after 50 seconds (Y-6), and the auxiliary program (Y-7) similar to the above (X-5) is fully executed.

In addition, in this example, the reason why the control during pouring water was not done in the same manner as during rinsing is because even if the finishing agent were to diffuse into the water after rinsing, most of it would come out as long as it overflowed. .

(G) Effects of the Invention If the dehydrating washing machine of the present invention is constructed, the washing treatment agent will not remain in the storage section as much as possible, so cleaning the storage section will be very easy.
