Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a detergent supply device for a washing machine, etc., for supplying detergent into the inside of a washing machine.

(Prior Art) Conventionally, for example, when washing in a washing machine, detergent is
In general, a person manually puts the amount per mouth into the washing machine's washing tub.

(Problems to be Solved by the Invention) However, in the above-mentioned method, when adding detergent, the detergent gets on the hands, which is bothersome, and the amount of detergent varies depending on the size of the detergent. By the way, when doing laundry in a washing machine, the amount of detergent is 0.0% by weight relative to the amount of water.
2U%] is said to have the highest cleaning efficiency, and therefore it is desirable to add detergent at that ratio. However, in the case where the detergent is added in a 1-1 portion as described in I-1, the amount of detergent is often too large or too small relative to the amount of water.

The present invention consists of 1. This was done in view of the circumstances in the article, and the purpose is to provide a washing machine, etc. that can always supply the appropriate amount of detergent without any hassle, and that can also achieve this with an inexpensive configuration. to provide detergent dispensing equipment.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes a detergent storage container that accommodates and stores detergent,
A detergent delivery member is disposed inside the detergent storage container, and a spiral spring is provided which is wound up by an external operation to accumulate force and rotates the detergent delivery member by releasing the accumulated force. By the rotation of a detergent delivery member by a mainspring spring, detergent is sent to the detergent outlet side of the detergent storage container, taken out from the detergent outlet, and supplied into the inside of a washing machine or the like.

(Function) According to the method described in ``U,'' the detergent stored in the detergent storage container is supplied by the rotation of a detergent delivery member using a mainspring spring, so there is no need for human intervention. The amount of detergent supplied can be adjusted depending on the amount of winding of the main spring, that is, the amount of rotation of the detergent delivery member.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

In this case, both the left and right ends of the shaft 12 of the screw 11 penetrate the detergent storage container 6 and protrude outward, and the left end thereof is covered by a cover 14 attached to the detergent storage container 6. 1
Reference numeral 5 designates a mainspring spring disposed inside the cover 14, one end of which is connected to the shaft 12 of the screw 11 as shown in FIG.
Pin 1 is fixed to the left end of the cover 14 and the other end is provided to the cover 14.
6 and its tip is brought into contact with the inner surface of the cover 14. Furthermore, a ratchet wheel 17 and a cam 18 are mounted on the left end of the shaft 12 of the bipedal screw 11 to the left of the mainspring spring 15, respectively. Reference numeral 19 is a lock bin, and as shown in Figs. 5 and 6, the middle part is connected to the shaft 2.
a claw portion 2 that is rotatably supported by the cover 14 by a claw portion 2 that engages a tooth portion 17a of a ratchet wheel 17 at one end thereof;
1, a roller 22 is squared at the other end, and the claw portion 21 side is urged in the direction of the ratchet wheel 17, and the roller 22 is attached to the main body of the washing machine as shown in FIG. 1-L
The inclined portion 231- formed on the surface portion is adapted to be transferred. In this case, the inclined portion 23 is formed by the detergent storage container 6.
The opening is formed in an arc shape centered on a shaft 7 which is pivotally supported, and is gradually higher toward the front side. 21 engages with the ratchet wheel 17,
When the detergent storage container 6 is in the loading position, the claw portion 21 is disengaged from the ratchet wheel 17, as shown in FIGS. 7 and 8.

On the other hand, the cam 18 has an engaging portion 24 at one location on its outer periphery, as shown in FIG. Reference numeral 25 designates a leaf spring having a corrugated part 26 at one end that engages with the engaging part 24 of the cam 18, and the other end is attached to a support member 27 attached to the cover 14, and the corrugated part 25 is attached to the support member 27 attached to the cover 14. 26 is always brought into pressure contact with the outer peripheral surface of the cam 18. On the other hand, in FIG. 1, reference numeral 28 denotes an operation knob rotatably provided on the detergent storage container 6 on the right side of the screw 11. Based on the rotation of this knob, the screw is rotated via the internal gear 29 and the pinion 3o. 11 is amplified and rotated, thereby causing the mainspring spring 15 to turn 1.
- It's starting to get better. 31 is 1. of the detergent storage container 6. The lid opens and closes the front opening, and as shown in FIG. 2, the rear end (the left end in FIG. 2) is pivoted to the detergent storage container 6 via a shaft 32.

In the case of the configuration 1', when using the detergent storage container 6, first, a detergent (not shown), such as a powdered detergent, is stored and stored in the detergent storage container 6, and then the detergent storage container 6 is placed in a standby position. In this state, when the operation knob 28 is next rotated by a predetermined amount, the screw 11 is rotated via the internal tooth width 29 and the pinion 3o, and accordingly the ratchet wheel 17 and the cam 18 are rotated as shown in FIGS. 5 and 9. When the screw 11 is rotated together with the screw 11 in the direction roughly shown by arrow A in the figure, the mainspring spring 15 is wound up.At this time, the lock pin 19 is attached to the ratchet wheel as shown in FIG. The claw part 21 is kicked at the southern part 17a of the ratchet 17 and rotated in the direction of arrow B around the shaft 20, so that the ratchet i.
The same rotation of the wheel 17 and therefore the rotation of the screw 11 is allowed. When the rotation of the operating knob 28 is completed, the lock pin 19 engages the claw portion 21 with the ratchet wheel 17, and the roller 22 contacts the inclined portion 23, causing the ratchet wheel 17 to rotate. , thus locking the rotation of the screw 11. As a result, the mainspring spring 15 is stopped from returning and accumulates the unwound force. In this state, when the detergent storage container 6 is moved to the loading position prior to washing, the lock pin 19 will be moved so that the roller 22 is at the inclined portion 23].
As the roller 22 rolls, the roller 22 side is pushed up and rotated in the direction of arrow Bh (see FIG. 7) as shown in FIGS. Release the engagement. Then, the main spring 15 releases the accumulated force and pushes the screw 11. By rotating the ratchet, r-twheel 17 and cam 18 in the direction opposite to the direction of arrow A in 1-, and by rotating the screw 11,
The detergent stored in the detergent storage container 6 is sequentially sent to the detergent outlet 8 side, and is supplied into the washing tub 3 from the tip of the detergent outlet 8. The detergent in the detergent storage container 6 is stirred by the stirring member 9 being rotated by the rotation of the screw 11. When the screw 11 is rotated for a predetermined period, the plate that was in pressure contact with the cam 18 is stirred. The engaged portion 26 of the spring 25 engages with the engaging portion 24 as shown in FIG. 9, thereby stopping the rotation of the second cam 18 and therefore the rotation of the screw 11, and the detergent is washed. The supply into the tank 3 is stopped. When the supply of detergent is completed in this way, the detergent storage container 6 is rotated to the standby position.

As described in 1- below, according to this embodiment, the detergent stored in the detergent storage container δ is transferred to the screw 1 by the mainspring spring 15.
Since it is supplied into the washing tub 3 by rotation of 1,
Detergent can be easily supplied without getting detergent on hands. Moreover, in this case, the supply of detergent requires
Since the amount of detergent can be adjusted according to the amount of winding 1 of the mainspring spring 15, i.e., the length of the screw 11, it is possible to always supply the appropriate amount of detergent.
Since the mainspring spring 15 is used to rotate the screw 11 once, the driving source can be made cheaper than when the screw 11 is rotated by, for example, a motor. Since there is no need to take any material, it can be produced at a low cost overall.

In addition, especially in the case of the first embodiment, the detergent storage container 6 is made rotatable between the standby position and the input position, and the detergent is supplied by rotating from the standby position to the input position. This makes it easy to use, and since the detergent is directly supplied into the washing tub 3, the detergent does not stick to parts other than the washing tub 3. Further, the detergent storage container 6 can be placed in a standby position except when necessary, so that it does not protrude inward from the washing tub 3, so that it does not interfere with washing operations such as loading and unloading laundry. Historically, when replenishing the detergent storage container 6 with detergent, it is possible to replenish the detergent with the detergent storage container 6 in the loading position. Detergent can be easily replenished even when the machine is installed.

Note that the present invention is not limited to the above-mentioned embodiment shown in the drawings; for example, the detergent delivery member may be other than the screw 11 as long as the detergent is delivered by rotation. Further, the applicable equipment is not limited to washing machines, but can be applied to all equipment that functions using detergent, such as dishwashers, and can be modified as appropriate without departing from the gist.

[Effects of the Invention] As is clear from the above description, according to the present invention, the detergent stored in the detergent storage container is supplied into the inside of the washing machine etc. by the rotation of the detergent delivery member by the spring spring. Because of this, there is no need for human intervention, and the amount of detergent supplied can be adjusted according to the rotation of the winding spring, that is, the detergent delivery member, so you can always use the total amount of detergent. Furthermore, since the detergent delivery member is rotated by a spiral spring, it has an excellent effect that it can be manufactured at a lower cost than a motor.
