Description

[Detailed Description of the Invention] The present invention relates to an automatic loading device for soft finishing agent, etc., in a washing machine.

In conventional washing machines, in order to automatically feed the finishing agent into the rinse tank at the desired process, a loading container that stores the finishing agent for one load is placed in the operation panel box above the washing machine, and the finishing agent is placed in the operation panel box above the washing machine. Some products are rotatable between an input standby position where the finishing agent can be stored and an input position where the finishing agent is discharged into the rinse tank.

On the other hand, many of the finishing agents currently on the market have a high viscosity, and if you try to automatically feed them as they are, the residue will stick to the feeding container or channel, making it extremely difficult to use. Also, finishing agents colored in blue etc. may drip even after being added automatically.
Drops can continue to fall for many minutes and remain on the fabric even after all the washing machine cycles have been completed.
If the fabric dries with the stock solution still attached, the color of the stock solution may remain and the fabric may look very unpleasant.

Therefore, fresh water is poured into the input container to dilute the finishing agent stock solution and clean the container all at once.

Conventionally, this fresh water injection was carried out when the input container was in a horizontal position in the input standby position, but the injection water pressure could cause the input container to tilt or the diluted finishing agent would overflow from the container before it was needed. There is a risk that you may end up

Incidentally, if fresh water is injected immediately before the charging container starts the charging operation, such inconvenience can be prevented, but this requires a complicated mechanism for controlling the water supply valve.

The purpose of this invention is to eliminate the disadvantages of the above conventional example,
To provide a finishing agent charging device for a washing machine which has a simple structure and can inject fresh water into a charging container at a good timing when loading the finishing agent.

However, according to the present invention, the purpose of the lever is that in a device that automatically injects finishing agent into a rinsing tank by rotating a bucket serving as a finishing agent injection container, the finishing agent is inserted into the bucket when the finishing agent is in a substantially horizontal position. This is achieved by arranging the bucket so that it is located near the bottom when not injecting the finishing agent, and facing above when the bucket is tilted downward.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a vertical side view showing an embodiment of the present invention, and Fig. 2 is a plan view, in which a water supply valve 1 is placed in an operation panel box 2 at the top of the washing machine, and an inflow side joint 1a protrudes from the back side of the box 2. One end of the bypass hose 3 is connected to the bypass joint 1c provided integrally with the dehydrator side discharge joint 1b of the water supply valve 1, and the nozzle portion 3a at the other end of the hose 3 serves as a finishing agent injection container. It is placed near the bucket 4 so as to be located near the bottom when the bucket 4 is in a substantially horizontal state, and above it when the bucket 4 is tilted downward.

Note that the panel section 2a on the top surface of the panel box 2
A finishing agent inlet 5 is provided in this panel 2a, and a nozzle 6 for introducing the finishing agent into the bucket 4 is attached to the lower end of the panel 2a, to which operating equipment such as a timer is attached.

Various drive structures can be considered for the bucket cart 4, but to give one example, the bucket cart 4 has its center of gravity behind the rotating support shafts 4a, 4a' when it is empty, and the bucket cart 4 has its center of gravity behind the rotating support shafts 4a, 4a'. It is pivoted to maintain a horizontal state, and when filled with one dose of finishing agent from the finishing agent inlet 5, the center of gravity shifts forward due to the weight of this finishing agent and tilts downward.

Specifically, as shown in the figure, the bucket 4 is made wider at the front, but the wall thickness forming the bucket 4 is changed between the front and rear parts, so that the rear part is thicker and the center of gravity is at the rear when empty. It is also possible to do something like this.

A protruding locking piece 4b is integrally provided in a part of the bucket bag 4, and a locking protrusion 9 moved by a solenoid 8 is engaged with the protruding locking piece 4b. Note that the locking protrusion 9 is activated by a spring 10 that returns to its position after being pulled by the solenoid 8.
has. In the figure, reference numeral 11 denotes a split pin that fixes the locking protrusion 9 to the iron core of the solenoid 8.

Further, as shown in FIG. 4, the tip nozzle portion 3a of the bypass hose 3 faces upward only when the bucket 4 is tilted downward, and is positioned so that it can be injected into the bucket 4, and is fixed with screws or the like.

Next, the usage and operation will be explained. First, the finishing agent is injected from the inlet 5 and the bucket 4 is filled with the finishing agent for one use. In this state, the center of gravity of the bucket 4 moves forward, but the solenoid 8 is not activated and the locking protrusion 9 is caught on the locking piece 4b, so the bucket 4 maintains a horizontal state, and the nozzle part 3b of the bucket 4 is moved forward. It is located near the bottom.

When the set dewatering timer advances and the dehydrating and rinsing process approaches completion, the solenoid 8 is energized, the locking protrusion 9 separates from the locking piece 4b, and the bucket 4 tilts downward. In this state, the finishing agent inside falls and is thrown into a dewatering tank which is a rinsing tank below the panel box 2.

On the other hand, a part of the fresh water that enters the water supply valve 1 from a water supply source such as a water faucet and is poured into the dehydration tank from the joint 1b via the water injection hose is discharged from the nozzle part 3b via the bypass joint 1c and the bypass hose 3. is,
When the bucket 4 is in a horizontal state, the water discharged from it is poured into the dewatering tank.

When the bucket 4 is tilted, the bucket 4 is positioned in the channel of the water discharged from the nozzle section 3a, and the water discharged from the nozzle section 3a is poured into the bucket 4, diluting the finishing agent and coating the bottom surface of the bucket 4. Wash away.

Bucket 4, which is now empty due to no finishing agent, moves its center of gravity to the rear and automatically returns to a horizontal position.
Thereafter, when the dewatering process is completed, the power supply to the timer is stopped, the operation of the solenoid 8 is also released, the locking protrusion 9 engages with the locking piece 4b, and the bucket 4 is ready for filling with the next finishing agent.

As described above, the finishing agent dispensing device for a washing machine of the present invention is a device that automatically injects finishing agent into the rinse tank by rotating a bucket serving as a finishing agent dispensing container. Because it is installed so that it faces above when the bucket is tilted, fresh water for cleaning and dilution can be injected into the bucket at the right time without using a complicated valve control mechanism, and the device itself will not malfunction. A simple, inexpensive and highly reliable product can be obtained.
