Description

[Detailed description of the invention] The present invention relates to an injection device that injects finishing agent, etc. into a washing tub.Finishing agent, etc. is charged in advance into a container provided in a control box, etc., and stored. This stored amount can be poured into the washing tub at any time, so when adding finishing agent to the container, there is no need to take the trouble of measuring the amount of finishing agent, etc. to be added in a separate measuring container. This allows the user to measure and add the appropriate amount.

This will be explained below based on the drawings.

Reference numeral 1 denotes a machine frame, in which an outer tub 3 containing a washing tub 2 which also serves as a dehydration tub is elastically suspended by a hanging rod (not shown).

4 is a balance ring in which a liquid 5 is sealed.

A top plate 7 having a clothes input port 6 is attached to the upper end of the machine frame 1.

Reference numeral 8 denotes an upper lid that covers the clothes input port.

At the rear of the top plate 7, a control box 1 is installed together with the front panel 9.
The base 11 of the control box constituting 0 is integrally molded.

Electrical components such as a program timer 12 are built into the control box 10.

13 is a cover that covers the timer's legitimate child 14.

Reference numeral 15 denotes a water inlet body rotatably supported by a shaft 16, which receives water from the water supply solenoid valve and connects the outlet 1 to the water inlet body (not shown).
7 releases water.

The shaft 16 is supported by a bearing stand (not shown) that appropriately projects from the base 11, and a cam lever 18 is integrally formed with the shaft 16.

This shaft 16 is always biased counterclockwise by a spring (not shown) so that the outflow port 17 is at a position as shown by the dashed line in the figure.
At a predetermined time, the cam lever 18 is pushed by an operating cam 20 attached to the outlet 9 to rotate the shaft 16 against the spring, thereby changing the direction of the outlet 17 as shown by the solid line in the figure.

Reference numeral 28 denotes a bypass path that receives water coming out of the outlet 17 when the outlet 17 is at the position shown by the dashed line, and the tip of this bypass path opens toward the washing tub 2 from the front end of the control box 10.

The base 11 includes a container 21 in which a finishing agent is stored in advance.
are integrally molded.

A cover 22 is attached to the upper opening of this container 21.

This cover 22 has an opening 23 for introducing water from the outlet 17 into the container 21 when the outlet 17 reaches the solid line position in the figure, and an opening 23 for introducing the finishing agent into the container 21. A large opening 24 is provided and the container 21. A suction pipe 25 that sucks up the liquid inside by siphon action and a discharge pipe 26 that injects the sucked up liquid toward the washing tub 2 are integrally molded.

27 indicates both the above-mentioned tubes 25 and 26 to constitute a siphon tube.
It is a plug that seals the upper end opening of the.

A finishing agent is charged into the container 21 by a feeder 29 .

This input device 29 is shaped like a gutter and curved upward in an arc shape, and is inserted into the opening 24 of the cover 22 through a guide hole 30 provided in the front panel 9.

Here, the degree of upward curvature of the input device 29 is as follows: When the input device 29 is inserted all the way as shown by the solid line in the figure, when the entire input mold is tilted downward toward the tip and pulled out toward the front, as shown by the dashed line. The pulled-out part is set to be inclined downward toward the front side.

When it is pulled out, the finishing agent A', which is dripped from above, is collected in the pulled out area.

Further, the input device 29 is provided with a scale 31 at the top so that the amount withdrawn can be seen.

Here, this scale indicates the amount of finishing agent that can be stored in the drawer, and ultimately becomes a measuring scale for measuring the finishing agent.

To put the finishing agent into the container 21, pull out the dispenser 29 by the required amount, drop as much of the finishing agent as possible into the pulled-out area from above, collect it, determine the amount of finishing agent, and then When the dispenser is inserted deep, it slopes downward toward the tip as shown by the solid line, so that the finishing agent can be reliably introduced into the container 21.

In other words, the amount of the finishing agent is measured at the pulled-out portion of the dispenser 29 and then dispensed into the container.

A dispenser cover 32 that surrounds the dispenser 29 is integrally provided on the back surface of the front panel 9, and the tip of this cover 32 enters into the container 21 through the opening 24, so that finishing agent can be dispensed. Even if the finishing agent scatters around due to the force of inserting the inserter 29 all the way, this cover 32 ensures that all of it falls into the container 21 without wetting the electrical components. .

A stopper 34 is provided on the back side of the input device 29, which comes into contact with a protrusion 33 provided on the edge of the guide hole 30 when the input device 29 is pulled out, thereby regulating the amount of withdrawal.

Next, the operation will be explained.

This washing machine automatically performs a series of processes such as washing, rinsing, and dehydration using a program timer 12. During the final rinsing process, the cam lever 18 is pushed by an operating cam 20 to close the water inlet body 15. The outlet 17 is directed into the container 21 (solid line state), and otherwise the outlet 17 is directed toward the bypass path 28.

Therefore, during washing or intermediate rinsing, the water that comes out from the water supply solenoid and valve and is received by the water inlet body 15 passes through the bypass path 28 and is washed through the opening at its tip, since the outflow port 17 faces the bypass path 28. It is released into tank 2.

On the other hand, for the water supply during the final rinse, the outlet 17 is connected to the container 21.
Since the finishing agent A is poured into the container 21, the finishing agent A that has been stored in advance is diluted.

When the liquid level in the container rises, a siphon action is activated, and the diluted liquid is sucked up through the suction pipe 25 and poured into the washing tub through the discharge pipe 26.

At this time, a resistance plate 35 is integrally provided to protrude from the bottom surface of the container 21, and the water coming out from the outlet 17 is disturbed by the resistance plate 35 so that the finishing agent and water are sufficiently mixed.

The liquid in the container 21 is poured into the washing tub until the liquid level drops to the lower end of the suction pipe 25.

In the above description of the embodiment, the finishing agent injection device that puts the finishing agent into the container 21 has been described, but the injection device can also be used by putting detergent or bleach other than the finishing agent into the container. can.

According to the injection device of the present invention as described above, finishing agent, etc. is charged into the container in advance and stored, and the stored material is injected into the washing tub when necessary, and the finishing agent is added to the container. The amount of finishing agent, etc. to be added can be measured using a gutter-shaped dispenser that guides the finishing agent, etc., so the desired amount can be dispensed without having to take the trouble of measuring it in a separate measuring container, which saves time and effort. It's very convenient.

The finishing agent and the like can be reliably poured into the container using this dispenser.
