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, a device was devised that uses a magnet or the like to automatically dispense a soft finish agent at the end of rinsing. 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.

Here, for example, the soft finishing agent has a very high viscosity due to its characteristics, and its fluidity becomes very poor especially at low temperatures. Therefore, in the method of tilting the rinse case and letting the soft finishing agent flow in,
The connection time for maintaining the slope must be very long, resulting in a large time loss. In addition, the hose joint that holds the rinse case at an angle has a guide rib in the middle of the water supply hose that is introduced into the dewatering basket to improve the water pulling effect and allow the water supply hose to pass through the hose joint. To prevent backflow of water, the inlet at the bottom of the hose joint must be a small diameter hole. Therefore, extra
In some cases, it took a long time for the soft finishing agent to flow in, and the highly viscous soft finishing agent adhered to the rinse case and the inner wall of the hose joint and solidified, thereby hindering the displacement and rotation of the rinse case.

OBJECTS OF THE INVENTION The present invention solves the problems seen in the prior art and allows processing agents to be added in a short time.

1, and is located below the processing agent inlet 30 for soft finishing agent or the like.

In the above configuration, the operation will be explained next. In this example, the introduction of a lift 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 perform dehydration and 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 to create a soft effect on clothing. In this way, if a predetermined amount of the soft finishing agent is poured into the soft finishing agent feeding recess 20 before dehydration and rinsing, the soft finishing agent can be fed automatically.
There is no need to stop and add the soft finishing agent in the middle of the cycle.

Specifically, the rinse case 33 is also connected 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, the relationship is (α<β). So, (β−
The larger α), the greater the effect of the soft finishing agent flowing out, such as the slope of the rinse case 33.
However, in terms of the storage amount of the soft finishing agent, in order to secure a predetermined volume, it is better to set the value of α small and to increase the distance between the front surface of the overflowing surface 6 and both shafts 33a and 33b, as shown in FIG. As shown, it is advantageous in terms of design to increase the horizontal length as much as possible. The reason is that both shafts 33a, 33b and the overflow surface 6
The longer the distance from the front of the rinse case 3, the larger the displacement (storage space) required.
The center of gravity of the rinse spring 39 that holds the rinse case 33 is also separated from the vicinity of both shafts 33a and 33b.
This is because it becomes necessary to increase the biasing force of the magnet 49, and as a result, it becomes necessary to increase the attractive 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, the spring 53 installed between the plunger 50 and the first hook portion 37 is connected 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. The coil spring 53 also serves as a spring for stroke adjustment when the protruding pin 62 erected on the bottom surface of the hose joint 27 and the bottom surface of the rinse case 33 come into contact when the rinse case 33 rotates. Furthermore, by placing the input recess 20 in close proximity to the input port 21 and the rinse case 33, the amount of soft finishing agent input can be visually checked, making it easier to check whether there is insufficient injection or whether the input operation is correct. There is.

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 attaching it to the position, the first water supply hose 24
The water flowing inside will not flow into the hose joint 27, and the soft finishing agent will not flow into both shafts 33.
It can be poured evenly into the water supply route from the a 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 drain hole (not shown) may be separately 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.

In addition, a button 65 that can be slid up and down is disposed above the rinse case 33, and the rinse case 33 can be arbitrarily displaced and rotated by operating the button via the guide shaft 67. Remaining water after washing the remaining soft finishing agent with clean water, or residual water such as splashed water can be removed with one touch without any problems. At this time, the guide rib 69 of the rinse case is provided to prevent the guide shaft 67 from slipping.
In addition, the guide rib 3 located below the processing input port 30
By providing a water fountain 73 in a part of the hose joint 27, a high flow rate flows into the hose joint 27 through the water fountain 73 when water is supplied to the dewatering side, and the high viscosity soft finishing agent is distributed at an appropriate concentration. The soft finishing agent remaining in the rinse case or hose joint 27 can be removed by pouring it into the water supply hose. At this time, the magnet 49 is energized.
Even in the OFF state, the bottom surface of the rinse case acts as a waterproof wall to prevent water from splashing outside the hose joint.

Effects of the Invention As described above, according to the present invention, by providing a hose joint that holds a rinse case and has an inlet at the bottom and a water fountain located below the inlet, the inner surface of the hose joint is A small amount of water is ejected, which creates high viscosity.
For example, it is possible to dilute the soft finishing agent to an appropriate concentration to shorten the outflow time, and also to remove the soft finishing agent remaining in the hose joint, shortening the washing cycle or removing the soft finishing agent in the rinse case, etc. It is possible to prevent the displacement and rotation of the rinse case from being locked due to residual adhesion of finishing agent, etc.
