Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for dispensing processing agents such as soft finishing agents, bleaching agents, and detergents in washing machines.

Conventional structure and its problems In recent years, in order to give a soft effect to fabrics, a washing method has become popular in which a soft finishing agent is poured into a water tank at the end of rinsing and is soaked into the clothes to give a soft finishing effect. Ta.

Originally, this soft finishing agent has a cationic effect on clothing and has the property of adhering to clothing, so if you add it to the water tank at the same time as detergent and stir it, it will remove the stains from the clothing that were removed by the detergent. However, there is a risk that it will adhere to clothing together with the soft finishing agent and cause re-contamination. Therefore, the use of softening agents is usually carried out after washing and rinsing have been completed.

Therefore, it has been proposed that a soft finish agent can be automatically added at the end of rinsing using a magnet or the like. Among these, there is a structure in which a soft finishing agent is put into a rinse case, stored and held, and the rinse case is tilted using the suction stroke of a magnet, and the soft finish agent is thrown in.

With this structure, the rinse case is not tilted until a predetermined cycle time has elapsed, and remains fixed in a horizontal position. If fresh water is poured from the inlet to wash away the soft finishing agent, or if splashed water remains in the rinse case, the next time you add the soft finishing agent, the storage capacity of the rinse case will be exceeded. The softening agent overflows into the pipes and is dripped into the dehydration basket from the nozzle during the spin rinse process, causing recontamination of detergent-containing clothes and preventing sufficient softness and finishing effects. There was a problem.

OBJECTS OF THE INVENTION The present invention solves the conventional problems and provides a feeding device capable of feeding an appropriate amount of processing agent in a timely manner.

In the above configuration, the operation will be explained next. In this example, the introduction of a soft finishing agent to the dewatering side will be described.

As shown in Figure 7, the dewatering side rinse cycle is as follows:
First, the clothes washed in the washing tank 3 are transferred to the centrifugal dehydration basket 6.
One cycle consists of the following three steps: dewatering operation → stopping the centrifugal dehydrating basket 6 (as an example, stopping by an electromagnetic brake using full-wave rectification) → supplying water from the nozzle part 32 into the centrifugal dehydrating basket 6. , repeat this cycle three times to remove rinsing. Then, when water is supplied in the final rinse cycle, the magnet is energized, the rinse case 33 is tilted in the direction of arrow b in FIG.
It is poured into the interior of clothing to create a soft effect. In this way, if you put in a predetermined amount of the soft finishing agent from the soft finishing agent input recess 20 before dehydrating and rinsing, you can automatically add the finishing agent, and you don't have to stop the finishing agent in the middle of the cycle and add it. There will be no need to do that.

Specifically, the rinse case 33 is attached to the magnet 4.
As shown in FIG. 4, if the angle of the bottom surface of the rinse case 33 with respect to the overflow surface 60 is α, and the displacement angle of the rinse case 33 is β, then (α<β). It becomes a relationship,
The larger (β−α) is, the greater the effect of the soft finishing agent flowing out when the rinse case 33 is tilted. However, in terms of the storage amount of soft finishing agent 3, in order to secure a predetermined volume, it is better to set the value of α small and increase the distance between the front surface of the overflowing surface 60 and both shafts 33a and 33b. As shown, it is advantageous in terms of design to increase the horizontal length as much as possible. The reason for this is that the longer the distance between the shafts 33a, 33b and the front surface of the flood surface 60, the larger the displacement (storage space) is required, and the center of gravity of the rinse case 33 is further away from the vicinity of the shafts 33a, 33b. This is because the biasing force of the rinse spring 39 that holds the magnet 49 needs to be increased, and as a result, it becomes necessary to increase the suction force by changing the coil specifications of the magnet 49, leading to an increase in costs.

Therefore, in this embodiment, the first water supply hose 24 is extended from the second water supply valve 22, and both shafts 33a, 33b of the rinse case 33 are connected in a direction substantially parallel to the first water supply hose 24. position the
Rinse case 3 in the longitudinal direction of panel stand 11
By increasing the width of Rinse Case 3,
By locating the center of gravity of the main body of the magnet 3 in the vicinity of both axes 33a and 33b, the biasing force of the rinse spring 39 can be reduced, and the coil specifications of the magnet 49 can be made at low cost. Further, space can be saved by shortening the distance between the front surface of the overflowing surface 60 of the rinse case 33 and both shafts 33a and 33b.

The hose joint 27 and the first, second, and third waterproof walls 57, 58, and 59 of the rinse case 33 are connected to both shafts 33a, 33b of the rinse case 33.
This is a waterproof wall that prevents the soft finishing agent from adhering and solidifying near the shaft and causing rotational locks. Further, a coil spring 53 installed between the plunger 50 and the first hook portion 37 is attached to both shafts 3 of the rinse case 33.
The purpose is to ensure safety when the rotation locks due to freezing of water droplets 3a and 33b or solidification of adhering soft finishing agent. In addition, the coil spring 53 is attached to a protruding pin 62 that is erected on the bottom of the hose joint 27.
and the bottom of the rinse case 33.
It also serves as a spring for adjusting the stroke when it comes into contact when rotating. Moreover, the input port 21 of the input recess 20
By bringing the rinse case 33 to a recent position, the amount of soft finishing agent added can be visually checked.
It is now easier to check if there is insufficient injection or if the injection operation is being performed.

Further, a substantially arc-shaped guide rib 31 is provided between the treatment agent inlet 30 of the hose joint 27 and the connecting pipe 29, and both shafts 33a, 33b of the rinse case 33 are aligned approximately parallel to the connecting pipe 29. By coming to the position, the first water supply hose 2
4 will not flow into the hose joint 27, and the soft finishing agent will not flow into both shafts 3.
The water can be poured evenly into the water supply path from the 3a and 33b sides.

In addition, a drain hole 6 is provided on the bottom of the second water supply hose 28.
1, and a nozzle part 32 is provided at a position higher than this bottom surface.
By disposing a 32 into the centrifugal dehydration basket 6,
drop it into the water receiver cover 12 through the water drain hole 61,
Prevent malfunction. That is, a separate drain hole (not shown) may be provided at the bottom of the water receiver cover 12, and this drain hole may be made to correspond to the overflow hole of the washing tank 3.

Further, a button 65 which is the operating section of the operating means that can be slidably moved up and down above the rinse case 33
By displacing and rotating the rinse case 33 arbitrarily by operating the button 65 via the guide shaft 67, the soft finishing agent remaining inside the rinse case 33 is removed after washing with clean water. Alternatively, residual water such as scattered water can be removed arbitrarily with one-touch operation without any problems. At this time, the guide rib 69 of the rinse case 33 is provided to prevent the guide shaft 67 from slipping. In addition, by providing a water fountain 73 in a part of the guide rib 31 located below the treatment agent inlet 30, when water is supplied to the dewatering side, a fountain with a high flow rate flows into the hose joint 27 through the fountain 73. The high viscosity soft finishing agent can be made into an appropriate concentration and poured into the water supply hose, and the rinse case 33
Alternatively, the soft finishing agent remaining inside the hose joint 27 can be removed. At this time, even if the magnet 49 is de-energized, the lower surface of the rinse case 33 serves as a waterproof wall, and the water will not be scattered outside the hose joint 27.

Further, a surrounding rib 71 is provided near the input port 21,
In addition, by providing the slit-shaped auxiliary input port 72, the soft finishing agent input from the input recess 20 temporarily flows between the outer wall of the surrounding rib 71 and the input recess 20.
It is stored between the inner wall and gradually flows out from the auxiliary input port 72 into the input port 21.
Air vent portions are formed on both sides of the connecting rib 64, and no water film is formed.

Effects of the Invention As described above, according to the present invention, by using an operation means such as a button to arbitrarily displace and rotate the rinse case, residual water in the rinse case or remaining water inside and outside the rinse case, for example, a soft finish, can be removed. Since the removal method for the agent can be controlled with one-touch operation, it is possible to eliminate the problem of recontamination of clothes due to overflow of water from the rinse case of the soft finishing agent and prevention of sticking of the rinse case due to freezing of residual water, etc. It is something.
