Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of an automatic loading device for fabric softener, etc. in a fully automatic washing machine, and in particular, it provides an easy-to-use loading device for fabric softener, etc. without reducing the function of the balancer. This invention relates to an automatic loading device for fabric softener, etc. in a fully automatic washing machine that is integrated with a washing machine.

Conventionally, in this type of equipment, most of the container containing the fabric softener, etc. was molded separately from the balancer to which the container is attached, and some of the containers had an integrated flow path for the fabric softener, etc. to the outside of the container. I stayed there. For this reason, the container itself has a large shape and is not only inconvenient to use, but also occupies much of the space on the balancer to which the container is attached, which should originally be part of the balancer. This has caused drawbacks such as being a factor that reduces its performance.

The present invention eliminates the conventional drawbacks and provides an automatic dispenser for fabric softener, etc. for fully automatic washing machines that improves usability by having a configuration that does not reduce the function of the balancer even if a dispenser for fabric softener is provided. The purpose is to obtain.

The present invention will be explained based on the drawings.

FIG. 6 is a partial perspective view of a dispenser for softening agent, etc., in which the container is attached to the balancer of the present invention, and FIG. 11 is a cross-sectional view of the dispenser of the present invention when the dispenser of the present invention is used. FIG. 12 shows an example of a timer program used in the spin-drying process of the washing/spin-drying tank in the spin-drying step before rinsing.

The operation of the automatic loading device for softening agent, etc. (hereinafter simply referred to as loading device) of the fully automatic washing machine of the present invention will be explained with reference to FIG.

In the figure, 1 is an outer tank, 2 is a washing/drying tank, and 3
indicates a water tank.

Laundry and detergent are put into the washing and dewatering tank 2, the time switch 4 is operated, the water supply valve 5 is opened, and water is injected from the water supply hose 6. When a certain amount of water enters, the motor 7 rotates the pulsator 10 with the belt 9 via the pulley 8 to perform cleaning. Thereafter, the drain valve 11 is opened to drain the water, and then the motor 7 rotates the washing and dehydrating tank 2 to dewater by centrifugal force. Then pour water and rinse. Then drain and dehydrate. In this way, the rinsing cycle is performed several times and dehydration is performed at the end.Using the centrifugal force caused by the dehydration before rinsing during the above process, the balancer 12 is configured with a feeding device for the softening agent of the present invention. 13, the softening agent and the like are added.

As shown in FIGS. 2 and 3, the dispenser of the present invention is comprised of a dispenser main body T integrally constructed with a balancer and a stop-time holding box (hereinafter referred to as holding box) 14 for holding softener, etc.

The input device main body T includes a box storage chamber 18 that stores the holding box 14, a rotation holding chamber 19 adjacent to the box storage chamber 18 at the partition wall A, a perforation 18-1 provided in the partition wall A, the box storage chamber 18, and the rotation holding chamber. 19, a holding chamber 20 during stoppage and a holding chamber 24 during rotation are provided in parallel on the side partition wall 21, an outflow port 22 opens to the holding chamber 20 during stoppage provided in the side partition wall 21, and a bottom plate 19 inclined in the direction of the outflow port 22. ―
1. A structure consisting of a partition wall 23 having a gap between a lid provided between the holding chamber 20 during stoppage and the holding chamber 24 during rotation, and an inclined outflow port 25 provided at the bottom of the holding chamber 24 during rotation. Equipped with. On the other hand, the holding box 14 has an injection port 14-1 at the top and a holding chamber 1 at the time of stoppage.
5, a rear wall 16 and a cylindrical protruding hole 17 provided in the rear wall 16; By attaching the holding box 14 to the dispenser main body T as shown in FIG. 6, an automatic dispenser is constructed. After injecting the fabric softener etc. from the injection port 14-1, attach the holding box 14 to the balancer 12 and operate the time switch 4 to start operation.
4 remains held in the holding chamber 15 during stoppage, but when the water is drained and the washing/dehydrating tank 2 starts rotating for centrifugal dewatering, the feeder 13 for softening agent etc. also rotates at the same time. . When rotated, a centrifugal force acts on the softening agent, etc., pressing it against the rear wall 16 and flowing out from the hole 17 provided at the upper part of the rear wall 16. Since the hole 17 is fitted into the perforation 18-1 shown in Fig. 2, the softening agent and the like flow into the holding chamber 19 during rotation as shown in Fig. 2, and are then pressed against the wall and rotated for dewatering. The inside remains as it is, but when the rotation stops, it falls onto the bottom plate 19-1 of the holding chamber 19 during rotation. On the other hand, the bottom plate 19-1 of the holding chamber 19 during rotation is connected to the bottom of the second holding chamber 20 during stoppage, which is the next chamber, through a step and an outlet 22 provided in the partition wall 21, as shown in the figure. Because of this, the fabric softener, etc. is held in holding chamber 1 during rotation due to gravity.
9, flows out through the outlet 22 into the holding chamber 20 during stoppage and is held there. Even when rinsing is performed next, the fabric softener is retained as it is, but when the dehydration rotation is performed again, the fabric softener is retained during rotation by centrifugal force from the upper gap of the partition wall 23, as described above. It is held against the rear wall of the chamber 24. When spin-drying is completed and the rotation stops, it falls to the bottom due to gravity and flows out of the dispenser through the external outlet 25 provided at the bottom, resulting in water receiving tank 3 and washing/dehydration tank 2.
Fall between. In the above example, two sets of holding chambers during stoppage and holding chambers during rotation are used, but by providing several sets of these, it is possible to add a softening agent, etc. during rinsing after the several times of spin-drying. Become.

By the way, fully automatic washing machines are generally designed so that a washing course can be selected as shown in FIG. 9 depending on the degree of dirtiness of the laundry.

The timer program shown in Figure A is a so-called standard course diagram used when washing heavily soiled laundry, and the timer program shown in Figure B is a so-called saving course diagram used when washing relatively lightly soiled laundry. Figure. Since the degree of soiling of the laundry to be washed differs between the standard cycle and the economizing cycle, the amount of detergent used also differs, so it is common for the number of rinses to be different from the perspective of resource conservation. Therefore, in conventional automatic feeding devices for fabric softeners, etc., the number of times of rinsing and intermediate dehydration provided before rinsing differs depending on the washing course. Such inlets had to be provided as many as the number of selectable washing courses, for example 14, 14'.

By the way, the timer program for the saving course explained in FIG. 9B, as shown in FIG.
As shown in the figure, if you set a pause time t in the dehydration operation and program the softener etc. to flow out from the holding chamber during rotation to the holding chamber during stoppage, which is the next chamber, during this pause time t, you can open the inlet for each course. This eliminates the need for a dosing device.

If it is a conventional dosing device, L as shown in Figures 7 and 8.
If the dimensions are large, it will be difficult to attach it to the balancer, and in order to secure the necessary capacity of the dosing device, W.
As the size increases, the width of the balancer part becomes narrow as shown by a in the figure, which impedes the original function of the balancer.In order to ensure the performance of the balancer, it is necessary to make the shape of the convex part inward to the washing and dehydration tank. This method has drawbacks such as complicating the loading and unloading of laundry.

According to the configuration of the present invention, (1) only the first set of holding boxes can be freely attached, and it is possible to use a dispenser for softening agent, etc., which only has an injection port; (2) The parts that are operated when injecting softening agent etc. into the dispenser are miniaturized. (3) All the holding chambers except the first set of holding boxes are integrally molded with the balancer, so as shown in Figures 7 and 8. (4) The W dimension in Figures 3 and 8 can be made smaller. (5) ) Therefore, the effective space "a" of the balancer can be made larger than the conventional one, (6) the original function of the balancer is not impaired, (7) the inside of the washing and dehydrating tank is It is possible to reduce the protrusions even when loading laundry,
This produces effects such as easy removal.
