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 given a soft finish, a finishing agent for this purpose is added during rinsing.

(Problem to be solved by the invention) However, in a washing machine with a dehydrating function, the processes such as washing, draining, dehydrating, and rinsing are normally performed automatically, so the user does not know when to perform rinsing. It is very troublesome to add a finishing agent while anticipating this, and it is also difficult to apply finishing agents. In particular, in a type of washing machine with a dehydrating function in which each process is performed multiple times, the finishing process is performed during the final rinse, which is even more troublesome.

The present invention has been made in view of the above circumstances, and its purpose is to automatically adjust the finishing agent to the prescribed rinsing time by simply storing the finishing agent in a predetermined reservoir before the washing operation. Therefore, it is possible to conveniently release the user from the trouble of deciding when to add the finishing agent and from the constraints thereof,
Moreover, it is an object of the present invention to provide a dehydrating/washing machine which can realize this with a device having a simple configuration, which is easy to manufacture, can suppress high cost, and which also has good cleaning performance of the device itself.

[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 on the inner side of the balance ring of the rotating tank, a container attached to the recess, a storage portion for a finishing agent formed in the container, and the storage portion. A receiving part is formed in the recess corresponding to the above-mentioned recess, and receives the finishing agent released from the storage part during dehydration, and causes the finishing agent to flow down when the dehydration is completed.

(Function) According to the above means, if the finishing agent is stored in the storage section in advance before the washing operation, the finishing agent in the storage section will be released by the centrifugal force of rotation of the rotating tank during dewatering after the start of the operation. and can be received at the receiving section. 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 example of the present invention will be described below with reference to the drawings.

The steps of D ₃ and dehydration S ₃ are now performed automatically.
When the washing mode is set to the saving mode, as shown in Fig. 7, washing W, drain D ₁ , spin S ₁ , rinse R ₁ ,
The steps of drainage D ₂ and dehydration S ₂ are performed in sequence.

Now, in FIGS. 1 to 4, 24 is a recessed part formed inside the ring body 7 of the balance ring 6, and this is a recessed part formed from the upper part 24a to the lower part 24b.
It forms a two-tiered structure that extends toward the back. 25 is a vessel attached to this recessed part 24 so as to cover it;
This container body 25 has a storage section 26 formed in the upper part that occupies most of the area, and a storage part 27 that occupies the entire area in the lower part, and the back walls of these storage parts 26 and 27. 26a and 27a are inclined toward the recessed portion 24. Furthermore, a finishing agent receiving port 26b is provided at the upper end of the storage portion 26.
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 in line with the storage section 26 . On the other hand, each storage portion 26 is provided in the upper and lower intermediate portions and the lower end portion of the recessed portion 24.
and 27 form substantially horizontal shelf portions 29 and 30 located below, whereby receiving portions 31 and 3 corresponding to the respective storage portions 26 and 37 are formed.
2 is formed. Furthermore, the distal end 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 spaced part allows the insertion hole 3
3 is formed.

The operation of the above configuration will now be described. When performing a standard course washing operation, the finishing agent A for a soft finish (shown by the solid line in Figure 1) is added to the reservoir 2 in advance.
6 through the receptacle 26b, and then select and set the timer 23 and the standard course. As a result, each step shown in FIG. 6 is performed in sequence. Now, the washing operation has started and the first dehydration S ₁
When the cycle is reached, the rotating tub 4 is rotated, and the centrifugal force dehydrates the laundry in the rotating tub 4, and the finishing agent A in the first storage section 26 is also transferred to the back wall 26a. The finishing agent A is lifted up along the axis and released in the centrifugal direction, that is, in the direction of the first-stage receiving part 31, and the released finishing agent A is received by this receiving part 31 and is subjected to centrifugal force during the dewatering process, as shown by the two-dot chain line in FIG. The back surface of the receiving part 31 (the upper part 24 of the step part 24
a) is held in a stagnant state where it does not fall while being pressed. When the dewatering step _S1 is completed and the rotary tank 4 is stopped, 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. After this first dewatering step _S1 , the finishing agent A remains stored in the storage portion 27 during the rinsing _R1 and draining steps _S2 . Then, when the next dehydration step S ₂ begins, the finishing agent A in the storage section 27 is lifted and released by the rotational centrifugal force of the rotating tank 4 in the same way as described above, and then the final stage receiving section 3
You can take it in 2. In this case too, finishing agent A is dehydrated S ₂
During the stroke, it remains in this receiving portion 32. When the dewatering step _S2 is completed, the finishing agent A flows down from the receiving portion 32 through the charging hole 33 and is charged into the rotating tank 4. Finishing agent A is thus added in time for the rinsing R ₂ step after the dehydration S ₂ steps, that is, the final rinsing step. After this, the steps of drainage D ₃ and dehydration S ₃ are performed, and the standard course washing operation is completed.

Next, a case will be described in which a washing operation in the saving mode is performed. Finishing agent A is injected into the inlet body 28 in advance and stored in the storage section 27, and the timer 2
Select and set 3 as the saving course. As a result, the 7th
Each step shown in the figure is performed in sequence. In this case, the finishing agent A is released from the storage section 27 and received by the receiving section ₃₂ during the first dehydration S ₁ step, that is, the rinsing R ₁ step, which is performed only _once . At the end of the stroke, it flows down through the charging hole 33 and is then charged into the storage section 4. In this way, finishing agent A is added in time for _one rinse R process.

As described above, according to this embodiment, during the standard course washing operation in which rinsing is performed twice, if the finishing agent A is stored in the first storage section 26 in advance, the finishing agent A can be transferred to the first storage section 26. From receiving part 31
to the next storage section 27 via
from there to the rotating tank 4 via the final stage receiving part 32,
Since it is moved every time the water is dehydrated before the rinsing stage and is put into the rotating tank 4 before the final rinsing stage, finishing agent A can be added automatically in accordance with the final rinsing even though there are multiple rinses, thereby saving the user's time. You can be freed from the hassle and constraints of determining when to add finishing agents.
Furthermore, even during the washing operation in the economizing course where rinsing is performed once, the finishing agent A is stored in the final storage section 27.
If the finishing agent A is stored in the storage section 27 and the receiving section 32, the finishing agent A can be added in accordance with the rinsing process. Furthermore, according to this embodiment, the finishing agent A is moved using the rotational centrifugal force of the rotary tank 4 during dehydration in the pre-rinsing stage, so a simple configuration without special mechanical or electrical operation is required. The above effects can be expected.

Furthermore, according to this embodiment, the storage parts 26 and 27
is 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.
It is easy to manufacture such a device for automatically adding finishing agent, and it is also easy to clean. That is, when trying to form the storage part and the receiving part from an integrally molded product,
In other words, if both the storage part and the receiving part are formed in the vessel body, the structure will become quite complex and complicated.
Manufacturing becomes extremely difficult. In addition, since the finishing agent in the reservoir is forcibly released by centrifugal force, there is little remaining of the finishing agent attached to it, but in the receiving section, the finishing agent naturally flows down, so there is a lot of finishing agent remaining attached to it. Therefore, it becomes necessary to clean the integrally molded product, but such an integrally molded product cannot be cleaned well. However, in this embodiment, as described above, the storage parts 26 and 2
7 is formed on the side of the container 25, and the receiving parts 31 and 32 are formed on the side of the recessed part 24 of the balance ring 6. Therefore, the structure of the container body 25 can be made extremely simple, and the receiving parts 31 and 32 can be formed on the side of the container 25. The balance ring 6 can be obtained by using the wall of the balance ring 6 which is originally included in the rotating tank 4, and the productivity is generally improved.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 receiving port 26b of the first-stage storage section 26 is formed so as to face the laundry entrance/exit 6a of the balance ring 6, so that the finishing agent A can be easily introduced into the storage section 26, and operability is improved. good. Moreover, according to the present embodiment, for the storage section 26 having the socket 26b, the remaining storage section 27 and the receiving section 31,
32 also indicates a recessed portion 24 formed in the balance ring 6.
Since the balance ring 6 is provided in the balance ring 6, it is easy to put in and take out the laundry, and the balance 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 that prevents the movement of the liquid within the balance ring, but if the blocking member prevents the liquid from moving in the direction of correcting the unbalance during steady rotation, then It won't happen. Note that during steady rotation, the liquid moves along the outer side of the balance ring under the influence of a large centrifugal force. Considering this situation, the recessed portion 24 of this embodiment effectively prevents the movement of the liquid 9 when the rotation is started, and allows the movement of the liquid 9 during the steady rotation, and therefore has a balancer effect. It is excellent in

In the above embodiment, there are two storage parts and two receiving parts each.
However, a plurality of these may be provided depending on the number of times of rinsing. Furthermore, in the above embodiment, the rotary tank 4 has a large number of dehydration holes 5a and dewaters from the dehydration holes 5a. A rotary tank configured to release the water from there may also be used.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, 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 recessed portion formed on the inner side of a balance ring that the tank has;
A container attached to the recess, a reservoir for a finishing agent formed in the container, and a finishing agent formed in the recess corresponding to the reservoir to be released from the reservoir during dewatering.
