Description

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

(Prior Art) Conventionally, dehydrating and dehydrating washing machines have been configured to perform multiple rinses in a rotating tub that also serves as a washing tub and dehydrating tub, and to perform dewatering by rotating the rotating tub before each rinse. are provided. In this case, it is generally known that when adding a finishing agent to give the laundry a soft finish, it is most preferable to add it at the time of the final rinse.

(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 it is difficult for the user to spend the time required for rinsing. It is very troublesome to add a finishing agent while keeping an eye on the situation, and there is also the inconvenience of being restricted by it. In particular, in a type of dehydrating and washing machine in which each process is performed multiple times, the finishing agent is added 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 store the finishing agent in a predetermined storage section before the washing operation, and then add the finishing agent to the final rinse. It can be added automatically, thereby freeing the user from the trouble of deciding when to add the finishing agent and the constraints thereof, making it convenient,
Moreover, it is an object of the present invention to provide a dehydrating and washing machine that can achieve this with a simple configuration.

[Structure of the Invention] (Means for Solving the Problems) The present invention performs rinsing multiple times in a rotating tank that also serves as a washing tub and a dehydrating tank, and performs dewatering by rotating the rotating tub before each rinse. In this system, a plurality of reservoirs for finishing agents are provided, and a finishing agent is provided corresponding to the plurality of reservoirs to receive the finishing agent released from the reservoirs each time dewatering is completed, and the next step is carried out upon completion of dewatering. The first feature is that the finishing agent is provided with a receiving part for guiding and storing the finishing agent into the rotating tank, and an input hole provided in the final stage receiving part for introducing the finishing agent into the rotating tank upon completion of dewatering, and A second feature is that the balance ring of the rotating tank has a recessed part whose upper surface is covered by a part of the balance ring, and the recessed part is provided with the storage part, the receiving part, and the input hole part. have

(Function) According to the first feature of the above means, if the finishing agent is stored in the storage section before the washing operation, the finishing agent in the storage section will be transferred to the rotating tank during dewatering after the start of the washing operation. It is released by rotational centrifugal force and received at the receiving part. When the dehydration is completed, the finishing agent in the receiving section is flowed down, and based on this, the finishing agent is introduced into the rotating tank from the input hole.

Furthermore, according to the second feature of the above means, the storage section, the receiving section, and the charging hole are provided in the recess formed in the balance ring, so that the mechanism for charging these finishing agents is installed inside the rotating tank. It does not protrude much, and as a result, laundry can be taken in and out without any problem. Also, since the upper surface of this recess is covered by a part of the balance ring, the upper part of the balance ring is continuous with its annular shape, and as a result, the balance ring is covered from its lower end to its upper end. When concave portions are formed continuously, the strength decreases greatly due to the formation of the concave portions, but according to the means of the present invention, this decrease in strength can be reduced.

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

This drain valve 17 is opened during draining and dewatering. On the other hand, 18 is a lid frame attached to the upper end of the water tank 2, 19 is an upper cover attached to the upper end of the outer box 1, 20 is a laundry entrance/exit formed in the upper cover 19, and 21 is a laundry A lid for opening and closing the article entrance 20; 22 is an operation box disposed at the rear of the upper cover 19; 23 is a timer disposed inside the operation box 22; It is configured to perform washing in two ways, and when the standard course is selected, as shown in Fig. 6, washing W, drain D ₁ , spin S ₁ ,
Rinse R ₁ , Drain D ₂ , Dewater S ₂ , Rinse R ₂ , Drain
D ₃ and dehydration S ₃ steps are now performed automatically,
When the saving course is selected, as shown in Fig. 7, washing W, draining D ₁ , dewatering S ₁ , rinsing 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 recess formed in the inner part of the ring body 7 of the balance ring 6, and this is a concave part formed in the upper part of the ring body 7 whose upper surface is a part of the balance ring 6. It is covered by a lid body 8. The recess 24 has a two-stage shape with the lower part 24b deeper than the upper part 24a. Reference numeral 25 denotes a container removably attached to the recess 24 so as to cover it, and this container 15 has a storage section 26 that occupies most of the space at the top, and a storage section 26 that occupies most of the space at the bottom. A reservoir 27 occupying the entire area is formed, and back walls 26a and 27a of these reservoirs 26 and 27 are connected to the recess 2.
It slopes in four directions. Further, at the upper end of the storage portion 26, a finishing agent receiving port 26b is formed in an expanded shape so as to face the laundry inlet/outlet 6a of the balance ring 6. At the top of the container body 25 there is a storage section 27.
An input port body 28 that communicates with the storage section 26 is formed in line with the storage section 26 . On the other hand, approximately horizontal shelf portions 29 and 30 located below the openings of the respective storage portions 26 and 27 are formed at the upper and lower intermediate portions and the lower end portion of the recessed portion 24. Corresponding receiving portions 31 and 32 are formed.
Furthermore, the tip of the lower (final stage) 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 part 33 is formed by the spaced apart part.

The operation of the above configuration will now be described. When performing the standard course washing operation, the finishing agent A for soft finishing (shown by the solid line in Figure 1) is added to the reservoir 2 in advance.
6 through the receptacle 26a, and the timer 23 is selected and set to the standard course. As a result, each process shown in FIG. 6 is performed in sequence. Now, the washing operation has started and the first dehydration S ₁
When the process begins, the rotating tub 4 is rotated, and its 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 discharged in the centrifugal direction, that is, in the direction of the first stage receiving section 31, and the discharged finishing agent A is received by this receiving section 31 and is subjected to centrifugal force during the dehydration process, as shown by the two-dot chain line in Fig. 1. The back surface of the receiving part 31 (the upper part 24 of the recessed 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 is guided and stored from the receiving part 31 to the storage part 27 at the next and final stage. Therefore, rinsing after this _first dehydration step
In each step of R ₁ and drainage S ₂ , the finishing agent A remains stored in the storage section 27 . 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 is received by the receiving section 32 at the final stage. . In this case as well, the finishing agent A remains in this receiving portion 32 during the dehydration step _S2 . When the dehydration S ₂ process is completed, the finishing agent A is poured into the injection hole 3.
3 into the rotating tank 4. Thus, the finishing agent A is added in time for the rinsing R ₂ step after the dehydration S ₂ step, 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 is thrown into the rotating tank 4 through the charging hole 33. 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,
By moving the finishing agent A every time it is dehydrated before rinsing and putting it into the rotary tank 4 before the final rinsing, finishing agent A can be added automatically in accordance with the final rinsing, even though there are multiple rinses. You can free yourself from the trouble of deciding when to add finishing agents and from the constraints of that.
Furthermore, according to this embodiment, the finishing agent A is moved by using the rotating 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. Further, according to this embodiment, these storage parts 26, 2
7, the receiving parts 31, 32, and the charging hole 33 are provided in the recess 24 formed in the balance ring 6, so the mechanism for charging these finishing agents does not protrude into the rotating tank 4 so much, and as a result, You can put in and take out laundry without any trouble. Also, this recess 2
4 has a structure in which its upper surface is covered by a part of the balance ring 6, so that the upper part of the balance ring 6 is continuous with its annular shape, and as a result, the balance ring is continuous from its lower end to its upper end. In the case where a concave portion is formed by forming a concave portion, the decrease in strength becomes large due to the formation of the concave portion, but according to this embodiment, this decrease in strength can be reduced.

Furthermore, according to this embodiment, the inlet body 28 allows the finishing agent A to be directly charged and stored in the final stage storage section 27.
Since this is provided, finishing agent A can be automatically added in time with the rinsing even during the washing operation in the saving course in which rinsing is performed only once, thereby making it convenient. Furthermore, according to this embodiment,
Since the receptacle 26b of the first storage section 26 is formed so as to face the laundry entrance/exit 6a of the balance ring 6, the finishing agent A can be easily introduced into the storage section 26.
Good operability. Moreover, according to the present embodiment, the balance ring 6
Since it is provided in the recessed part 24 formed in , the workability of putting in and taking out the laundry is good, and the balance ring 6 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 to rotate, 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 is possible to provide a blocking member within the balance ring that immediately stops the movement of the liquid. Must not be. 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 at the time of starting rotation, and allows the movement of the liquid 9 during steady rotation, thus improving the balancer effect. It is excellent.

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. Further, 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 illustrated as the rotating tank, but this has a tapered circumferential wall and pumps water up to the upper end opening by rotation. 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 provides a plurality of reservoirs for finishing agents, provides a receiving section corresponding to each reservoir, and supplies the finishing agent to the rotating tank in the final stage receiving section. An input hole is provided to transfer the finishing agent to the next storage section after each dewatering process via each receiving section, and the finishing agent is then introduced into the rotating tank at the end of the dehydration stage before the final rinse. Therefore, even though multiple rinses are required, the finishing agent can be automatically added in time with the final rinse, thereby freeing the user from the trouble of determining when to add the finishing agent and the constraints thereof, making it very convenient. Moreover, this can be achieved with a simple configuration, and therefore manufacturing is easy and cost increases can be suppressed.
Since the storage section, the receiving section, and the charging hole are provided in this recess, the mechanism for charging these finishing agents does not protrude into the rotating tub, and as a result, laundry can be taken in and out without any trouble. Furthermore, since the upper part of the recess is covered by a part of the balance ring, a dehydration/dehydration/washing machine is provided which has effects such as being able to suppress a decrease in the strength of the balance ring. can be provided.
