Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a washing machine that performs both rinsing and dehydration prior to rinsing.

(Prior Art) Conventionally, there have been provided dehydrating and dehydrating washing machines in which rinsing is performed in a rotating tub that serves as a washing tub and dehydrating tub, and dehydration is performed in a preceding stage. In a dehydrating and washing machine, if the laundry is to be finished in a soft manner, a finishing agent for this purpose is added during rinsing.

(Problems to be Solved by the Invention) However, in the dehydrating and dehydrating washing machine, processes such as washing, draining, dehydrating, and rinsing are usually performed automatically.
For the user, it is very troublesome to add the finishing agent at the right time for rinsing, and it is also inconvenient for the user to be constrained by this. In particular, in a type of washing machine that performs each cycle multiple times, the lifting time is during the final rinse, which is even more troublesome.

The present invention has been made in view of the above-mentioned circumstances (1), and therefore, its purpose is to store the finishing agent in a predetermined storage section before the washing operation. can be automatically added in accordance with the predetermined rinsing, thereby freeing the user from the trouble of deciding when to add the finishing agent and the constraints thereof, making it convenient, and this can be realized by a device 1t with a simple configuration, Furthermore, it is an object of the present invention to provide a dehydrating/washing machine which is easy to manufacture and can suppress high costs, and which also has good cleaning properties.

[Structure of the Invention] (Means for Solving the Problems) The present invention performs rinsing in a rotating tank that serves as a washing tub and a dehydrating tank, and also performs dewatering by rotating the rotating tub before rinsing. A recess formed in the inner side of the balance ring of the rotating tank, a container mounted in the recess, a storage portion for a finishing agent formed in the container, and the storage portion. A receiving part is formed in the recessed part corresponding to the above-mentioned recessed part, and receives the agent released from the storage part during dehydration, and causes it to flow down when the dehydration is completed.

(Function) According to the above means, if the finishing agent is stored in the storage section before the washing operation, during dewatering after the start of the washing operation,
The finishing agent in the reservoir is released by the rotational centrifugal force of the rotating tank, and is received by the receiving part. When the dehydration is completed, the finishing agent in the receiving portion is flowed down, and based on this, the finishing agent is introduced into the rotating tank.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

First, in Fig. 5, 1 is an outer box, 2 is a water tank disposed inside the outer box 1 via an elastic suspension mechanism 3, and 4 is a rotating washing machine/dehydration tank disposed inside the water receiver 2. The rotating tank 4 is composed of a tank main body 5 having a dewatering hole 5a and several balance rings 6 arranged on the inner periphery of the upper end of the tank main body 5. Furthermore, this balance ring 6 is formed into a hollow shape by a ring body 7 and a lid body 8, and a liquid 9 is sealed therein as a balance weight. Reference numeral 10 indicates a stirring blade disposed at the inner bottom of the rotating h"!4, and reference numeral 11 indicates a mechanism section 12 and a drive motor 13 disposed at the outer bottom of the water receiving tank 2.
12 and a belt transmission device 14 that connects them, and this drive mechanism 11 is, as is well known,
When washing and rinsing the rotation of the drive motor 13, the stirring blade 1
0, and also to the rotating tank 4 during dewatering. 15 is a drain port formed at the bottom of the water receiving tank 2;
6 is a drain pipe whose one end is connected to the drain port 15 and the other end is led out of the outer box 1; 17 is a drain valve installed in the drain pipe 16; this drain valve 17 is used during draining and dewatering; It is something that is liberated. On the other hand, 18 is a lid frame attached to the upper end of the water tank 2, 19 is a cover made of several layers at one end of the outer box 1, and 20 is a laundry entrance/exit formed in the upper cover 19;
21 is a lid for opening and closing the laundry entrance/exit 20, 22 is an operation box provided at the rear of the cover 19, and 23 is a 1/■ production box 22.
The timer 23 is configured to select the standard course and the saving course for the washing operation (when the standard course is selected, the timer 23 is set to the standard course and the saving course). As shown in Figure 6, washing (W) and draining (DI).

Dehydration (Sl), rinsing (R1>, drainage (D2)).

Dehydration (S2), rinsing (R2), drainage (D3).

Each step of spin-drying (S3) is now performed automatically, and when washing is set to the saving mode, wash (W), drain (Dt), spin-dry (Sl), and rinse ( R1
), drainage (D2), and dehydration (S2) are performed in sequence.

Now, in FIGS. 1 to 4, 24 is a recess formed inside the ring body 7 of the balance ring 6, and this recess has a two-stage shape in which the lower part 24b is deeper than the upper part 24a. Reference numeral 25 denotes a container that is placed in the recessed part 24 so as to cover it, and this two-part body 25 has a storage part 26 that occupies the large 'F' in the upper part, and a storage part 26 in the lower part. A storage section 27 occupying the entire area is formed therein, and back walls 26a and 27a of these storage sections 26 and 27 are inclined toward the recessed section 24. Further, at the upper end of the storage section 26, a lifting agent receiving port 26b is formed in an expanded shape so as to face the laundry inlet/outlet 6a of the balance ring 6. An inlet body 28 communicating with the storage section 27 is formed in the upper part of the container body 25 by the storage sections 26 and 112. On the other hand, substantially horizontal shelf parts 29 and 30 located below the openings of the respective storage parts 26 and 27 are formed in the -I- lower intermediate part and the lower end part of the recessed part 24, so that each storage part Receiving parts 31 and 32 corresponding to 25 and 27
is formed. Furthermore, the tip of the lower receiving part 32 is spaced apart from the back wall 27a of the storage part 27 of the container body 25, and the feeding hole 33 is formed by the spaced apart part.

The operation of the above configuration will now be described. When operating the mark course for washing, fill the reservoir 26 with finishing agent A (shown by the solid line in FIG. 1) for soft finishing in advance.
6b, and the timer 23 is selected and set to the mark course. As a result, each process shown in FIG. 6 is performed in sequence. Now, when the washing operation starts and reaches the first dehydration (Sl > stroke), the rotating tub 4 is rotated, and its centrifugal force causes the rotation (1!4) to dehydrate the laundry. (in the storage section 26 of the first stage)
1. The treatment agent A is lifted up along the back wall 26a and released in the centrifugal direction, that is, in the direction of the first stage receiving portion 31, and the released treatment agent A is received by this receiving portion 31 and dehydrated. During the stroke, due to centrifugal force, the 1st m = receiving part 31 shown by the dotted chain line
It is kept pressed against the inner surface (the first part 24a of the stepped part 24) and does not fall. When the dehydration (Sl) process is completed and the rotating tank 4 is stopped 1-, the centrifugal force disappears, so the water flows down from the receiving part 31 and is guided and stored in the storage part 27 at the next and final stage. Therefore, this first dehydration (S
In each of the rinsing (R1) and draining (Sl) steps after the l) step, the finishing agent A remains stored in the storage portion 27. Then, when the next dehydration (Sl) step begins, the lifting agent A in the storage section 27 is lifted and released by the rotating centrifugal force of the rotating tank 4, as described above, and is then released from the receiving section 32 at the final stage. I can accept it. In this case too, finishing agent A is dehydrated (Sl
) During the stroke, it is kept in this receiving portion 32. When the dehydration (Sl) process is completed, the finishing agent A is applied to the receiving portion 3.
2, flows down through the charging hole 33 and is charged into the rotating tank 4. Thus, the rinsing (
R2) step, ie, the final rinsing step, II:] Refining agent A is added. After this, drain water (D3
) and spin-drying (s3) are performed, and the washing operation of the standard course is completed.

Next, a case will be described in which a washing operation in the saving mode is performed.

The lifting agent A is put into the inlet body 28 in advance and stored in the storage part 27, and the timer 23 is selected and set to the saving course. As a result, each process shown in FIG. 7 is performed in sequence. In this case, the finishing agent A is the initial dehydration (Sl)
During the dehydration (Sl) step, which is the first stage of the rinsing (R1) step, which takes place only once, water is released from the storage section 27 and received by the receiving section 32, and then flows down through the input hole 33 at the end of the dehydration (Sl) step. , and is then put into the storage section 4. In this way, the polishing agent A is added at the same time as the rinsing (R1) process.

According to this embodiment, in the washing operation of the 1-vote quasi-course in which rinsing is performed twice, fL-1 is preliminarily applied to + and N.
: When the chemical agent A @ ; is stored in the storage section 26 of the horn stage, the chemical agent A is transferred from the first storage section 26 to the storage section 27 of the next stage via the receiving section 31, and then from the storage section 27. Finishing agent A is transferred to the rotating tank 4 via the receiving part 32 at the final stage for each dehydration stage before rinsing, and is then introduced into the rotating tank 4 at the stage before the final rinsing. It can be added automatically in time with the final rinse, thereby freeing the user from the trouble of determining when to add the cleaning agent and from the constraints thereof.

Furthermore, even during the washing operation in the economizing course where rinsing is performed once, if finishing agent A is stored in the storage section 27 at the final stage, the finishing agent A is stored in the storage section 27 and the receiving section 32. can be added according to the rinsing process. Moreover, according to this embodiment, since the centrifugal force of rotation of the rotary tank 4 during dehydration in the pre-rinsing stage is used to move the polishing agent A, a special tsuki (a simple lever without closing operation or electrical operation) is used. (11(～
You can expect 23 songs to be sung at the same time.

Furthermore, according to this embodiment, the storage parts 26 and 27 are connected to the container 2.
5 side, and the receiving parts 31 and 32 are formed on the balance ring 6 side.
Since it is formed on the side of the recess 24, it is easy to manufacture a device for automatically adding the lifting agent (1t), and it is also easy to clean. In other words, if you try to form the storage part and the receiving part from an integrally molded product, that is, if you try to form both the storage part and the receiving part in the container body, the structure will be quite complex and complicated, making it difficult to manufacture. It becomes extremely difficult. In addition, since the finishing agent in the reservoir is forcibly released by centrifugal force, there is little remaining of finishing agent, but in the receiving section, the finishing agent flows down naturally, so there is less sticking of finishing agent. There is a lot of residue left, and this makes it necessary to clean the integrally molded product, but such integrally molded products cannot be cleaned well. However, in this embodiment, as described above, the storage parts 26 and 27 are formed on the container 25 side, and the receiving parts 31 and 32 are formed on the recessed part 24 side of the balance ring 6, so the structure of the container body 25 is changed. It can be made very simply, and the receiving parts 31 and 32 can be
The balance ring 6 can be obtained by using the wall of the balance ring 6, which improves the productivity in general, and furthermore, when the vessel body 25 is removed, the receiving parts 31 and 32 are exposed.
As a result, the receiving parts 31 and 32 can be cleaned very easily, and the storage parts 26 and 27 can also be cleaned very easily.

In particular, according to this embodiment, the receptacle 26 of the first stage storage section 26
b is formed so as to face the laundry inlet/outlet 6a of the balance ring 6, so that the finishing agent A can be easily put into the storage part 26, resulting in good operability. Moreover, according to this embodiment, the socket 2
6b, the remaining storage portion 27 and receiving portions 31 and 32 are also provided in the recessed portion 24 formed in the balance ring 6, making it easy to put in and take out laundry. The ring 6 also has an excellent balancer effect. In other words, liquid-filled balance rings usually have poor unbalance correcting action because the centrifugal force is small when the rotating tank starts rotating, and therefore, if the rotating tank tilts due to unbalance when starting to rotate, the lowest part of the balancer A situation occurs in which the liquid moves and concentrates, further aggravating the unbalanced state. In this case, the liquid moves in the lower part of the balance ring because the centrifugal force is small. Therefore, as a countermeasure to this problem, it may be possible to provide a blocking member to prevent the movement of the liquid within the balance ring, but that is not the case! 11 The stopper must not prevent the liquid from moving in the direction of correcting the unbalance during steady rotation. Note that during steady rotation, the liquid is subjected to a large centrifugal force and moves along the outer side of the balance ring. If this situation is compared, the recessed portion 24 of this embodiment is designed to accommodate the liquid 9 at the time of starting rotation.
This effectively prevents the movement of the liquid 9 and allows the movement of the liquid 9 during steady rotation, thus providing an excellent balancer effect.

In the above embodiment, two storage parts and two receiving parts each are provided, but a plurality of these may be provided depending on the number of times of rinsing. Furthermore, in the above embodiment, the rotating tank 4 which has a large number of dehydrating holes 5a and dewaters from the dehydrating holes 5a is exemplified as the rotating tank. A rotary tank configured to pump water up to a point and release it from there may also be used.

The pond water invention is not limited to the embodiment shown in the drawings marked -1-, but can be implemented with various modifications without departing from the gist.

[Effects of the Invention] As explained above, the present invention is characterized in that rinsing is performed in a rotating tank that also serves as a washing tub and a dehydrating tank, and dehydration is performed by rotating the rotating tub before rinsing, in which A recess formed on the inner side of the balance ring of the tank, a container attached to the recess, a reservoir for finishing agent formed in the container, and the above-mentioned container corresponding to the reservoir. It is provided with a receiving part formed in the recessed part to receive the finishing agent released from the storage part during dehydration and to make it flow down when the dehydration is completed, and with this, (+: 1
．． - By simply storing the rinsing agent in a predetermined reservoir before the washing operation, the finishing agent can be automatically added in accordance with the predetermined rinsing.
