Description

[Detailed description of the invention]

``First Invention'' (Industrial Application Field) The present invention relates to a detergent supply device for washing machines, etc., which supplies powdered detergent to the inside of equipment such as washing machines. Conventional technology) Conventionally, for example, in a washing machine, it has been considered to automatically supply powdered detergent to a washing tub inside the washing machine.This machine stores powdered detergent in a designated detergent storage case. The detergent outlet at the bottom of the detergent storage case is left open. Therefore, from the detergent outlet, the powder stored in the detergent storage case is supplied. There is a problem that detergent drips off even when the detergent is not being supplied due to the vibrations of the washing machine during operation 11H, and especially when it comes out during rinsing after washing or during spin-drying, it can cause damage to the laundry. If the detergent outlet of the detergent storage case is supplied with detergent, the detergent outlet of the detergent storage case is opened when the detergent is supplied, and the lid is closed except when the detergent is supplied. (Invention or problem to be solved) However, the detergent 1) in the detergent storage case is also considered to be free from moisture and humidity, which is characteristic of washing machines and other equipment that uses this type of detergent. Due to this, powdered detergent tends to harden and stick (the lumps may get caught between the detergent outlet and the lid, causing the lid to be incompletely closed, and the powdered detergent will come out from the gap and fall out, causing washing problems). The present invention was made in view of the above-mentioned situation, and therefore, the first objective is to prevent detergent from being deposited on the detergent storage case other than when the detergent is being supplied. Powdered detergent that inevitably comes out from the detergent outlet and falls on the laundry

[It is possible to more reliably prevent 1st wear, and achieve this with a rational structure, and the supply of powdered detergent itself can be performed more smoothly, so that 491 leftover clothes can be prevented again. To provide an excellent detergent supply device for a washing machine, etc. that can be used in washing machines. [Structure of the Invention] (Means for Solving the Problems) A detergent supply device for a washing machine or the like of the present invention stores powdered detergent in a detergent storage case and supplies the powdered detergent to a river from a detergent outlet at the bottom of the detergent storage case. When the detergent is supplied to the detergent storage case, the powder detergent discharged from the "double-layer detergent outlet 1" is allowed to fall, and the lower part of the detergent outlet is blocked except when the detergent is supplied. It is characterized by the provision of a detergent fall prevention part shrine located there to prevent the detergent from falling. In this case, the detergent fall prevention member is preferably a detergent supply shoe I, which receives the powdered detergent coming out of the detergent storage case's mouth when the detergent fjt is supplied and guides it to the supply destination. Further, it is preferable that the detergent receiving surfaces of detergent dropping stop part q1) r and I, which serve as detergent supply chutes, are water-repellent surfaces. (Function) According to the above means, even if powdered detergent comes out and falls from the detergent outlet of the detergent storage case other than when the detergent is being supplied, the detergent fall prevention part 2) prevents it from falling further to the lower blade. I can do something. In this case, if the detergent fall prevention member is a detergent supply unit that receives the powdered detergent from the detergent 1+'1 port of the detergent storage case when the detergent is supplied and guides it to the supply destination, it would be possible to combine them into one It can be done with just one part and does not require two parts. Further, if the detergent receiving surface of the detergent fall prevention part H, which is used to supply the detergent 1, is a water-repellent surface, it is possible to improve the dispersion of the powder detergent during supply. (Example) Hereinafter, an example in which the present invention is applied to a detergent supply device for a fully automatic washing machine will be described with reference to the drawings. First, in FIG. 1, ] indicates the outer box of the fully automatic washing machine body, in which an inner tank 2 serving as a washing tub and a dewatering tank and an outer tub 3 serving as a water receiving tank are arranged.

The closing force (=t'W) is exerted by the spring 22. Also, in FIG. This water filler 213 has a large number of tooth-like protrusions 24 inside, has a water fill port 25 at the bottom, and has a water inlet 26. From the position directly below 26 to the rear, there is a stopper rib 2 on the bottom surface.
7) with a water passage l' 28 at its front end -C
A detergent fall barrier 11 member 29 is provided at a lower rear portion of the water flow guide 28. In this case, the two detergent fall prevention members 11° also serve as detergent supply units, and as shown in Fig. 3, they are generally shovel-shaped, and have guide ribs on both sides and in the middle, respectively. 30, 31.32. In addition, a shaft portion 33 is protruded outward from the middle part of the back of the detergent fall prevention portion side 29, and this shaft portion 33 allows the detergent fall prevention portion side 29 to
The whole part is pivoted so that it can be moved up and down. Further, a lever portion 34 extends rearward from the shaft portion 33, and its tip portion is loosely fitted into the lower end portion of the link 35. The link 35 is attached to a crank 37 that is connected to the output shaft of a drive unit 1-36 that includes a motor, a speed reduction mechanism, a solenoid, etc. (not shown). Furthermore, an engagement recess 38 is formed at the rear end of the detergent fall prevention member 29, and this is engaged from below with an engagement protrusion 39 protruding from the rear of the small lid 2]. It's sleeping like that. Also, in Detergent Fall Prevention Department Publication 29, spring 40
In addition, the entire upper surface of the detergent fall barrier side 29, which is the detergent receiving surface, is coated with, for example, fluorine as shown in FIG. As a result, a water-repellent surface 4] is formed. Next, the operation of the above structure will be described. First, the detergent storage case 9 (inner case 8) of the detergent supply device 6
), as shown in FIGS. 1 and 2, a predetermined amount of powdered detergent 42 is stored in the container. is energized. Therefore, the water supply valve is opened, and the water supplied through the water supply valve is supplied into the inner tank 2 through the water injector 25 via the water injector 23, and at the same time reaches the water flow guide 28 through the water inlet 26. Furthermore, water is supplied into the inner tank 2 from this water passage guide 28. At the same time, the crank 37 is rotated by the motor of the drive unit 36 to pull up the link 35. Therefore, the two parts of the detergent fall barrier 11 may have been in a state where the rear part was tilted backwards and the front part was in a substantially horizontal state due to the spring force of 4 degrees, as shown in FIG. is pulled up by the link 35 and rotates or tilts about the shaft 33 so that the rear part is raised and the front part is lowered. Here, when the detergent drop prevention member 29 that has been rotated in this way reaches the final tilting position shown in FIG. 29 is stopped from further rotation and is held in its stopped position by the solenoid of the drive unit 36, which continues to be energized. Also, depending on the rear part of the detergent drip prevention part 129,
The engagement recess 38 engages the engagement part 39 of the small lid 2 from below and pushes it up, so the small lid 2 is opened. At this time, although not shown, the portion of the engaging convex portion 39 that contacts the engaging concave portion 38 is oblique, and the detergent fall prevention portion 11
The upward displacement of the rear part of the one member 29 is changed into the displacement of the small lid 2 in the opening direction, so that the opening can be smoothly performed. Further, due to the tilting of the two detergent fall prevention members 11, the water flow guide 28 is also pushed up by the detergent fall stopper member 29 via the stopper rib 27, as shown in FIG. After the detergent falls, the detergent is released from being pushed up by the stopper member 2 and descends, changing to a backward tilted state, not shown in FIG. Therefore, the water that has reached the water passage kite 28 from the water passage port 26 of the water injector 23 flows backward on the water passage guide 28 as shown by the arrow in FIG. falls onto the upper member 29, and further this δ
1 member 29, especially the guide rib 30.3
It flows forward between 2 and is supplied into the inner tank 2. However, after a delay of, for example, about 5 seconds, the detergent delivery member 1
5 drive motor 19 is energized and transmits its rotational force to detergent delivery member 15 through transmission mechanism 18 to rotate it, particularly to drive the coil to rotate in a spiral direction. Accordingly, based on this, the powdered detergent 42 in the case 9 is advanced through the detergent delivery section 14, taken out from the small lid 21 at the tip or the open detergent outlet 20, and is deposited onto the detergent fall prevention member 29, which is also particularly is dropped between guide ribs 30 and 32. Therefore, the detergent drop prevention part 29 is at the final tilting position mentioned above, receives the dropped powder detergent 42, and transfers it onto the detergent drop prevention part +7129 (between the guide ribs 30 and 32).
Along with the flowing water, the water is guided down into the inner tank 2 which is the supply destination. Then, when the set time elapses after the supply of the powdered detergent 42 starts, the motor 1 for driving the detergent delivery member control 5 is activated.
Then, the solenoid of the drive unit 36 and the water supply valve are each cut off, thereby stopping the supply of the powdered detergent 42 [I-'], and the detergent fall prevention member 29 is moved by the spring force of the spring 40. It is returned to its original state, and accordingly, the small lid 21 is also returned to its closed state by the spring force of the spring 22, and water supply is further stopped. Here, the detergent drop prevention member 29 that has been restored to its original state has its rear part tilted backwards and its front part approximately horizontal, as described above, and especially the front part which is approximately horizontal. In this state, the powdered detergent 42 that comes out from the gap caused by the solidified powdered detergent 42 being caught between the small lid 21 and the detergent outlet 20 is caught, and the powdered detergent 42 that falls is blocked. Furthermore, it prevents the powder from falling downward, thereby preventing the powdered detergent 42 from dripping onto the laundry after washing, making it possible to obtain good stiffness during washing. In addition, in this case, the detergent drop prevention department publication 29
It functions effectively in the case of water splashing from inside or by preventing it from coming into contact with the detergent outlet 20. In the case of the above embodiment, the detergent fall prevention member 29 serves as a detergent supply chute that receives the powdered detergent 42 discharged from the detergent 1] 20 during detergent supply and guides it to the supply destination, as described above. Since these can be done with one part and two parts are not required, the structure can be mixed rationally and the cost can be reduced. The two detergent receiving surfaces on the side of the detergent fall prevention part, which is the feeding unit, are water-repellent surfaces 41, which can improve the sliding of the powder detergent 42 during supply. supply itself,
It can be used more smoothly, and the remaining parts can also be cleaned more easily.Therefore, it can be used in low water pressure areas, and is especially suitable for use in detergent removal +L section publication 29 Even if water is not flowed on the detergent receiving surface during detergent supply, a sufficient cleaning effect can be obtained by simply flushing a small amount of water after one co-supply. The invention is not limited to the embodiments shown in the drawings;
” One member 29 does not also serve as a detergent QIH supply chute, and in particular, the detergent outlet 20 directly faces inside + IIJ 2 etc. = 13
- If the configuration is such that powdered detergent 42 is supplied, the detergent fall prevention member 29 simply allows the powdered detergent 42 to fall when the detergent O is being supplied, and prevents the powdered detergent 42 from falling at times other than when the detergent is being supplied. In addition, the detergent receiving surface on the side 29 of the detergent dripping prevention 1 may be replaced with a water-repellent surface 4.
1 may be carried out as necessary, and the manufacturing method for producing E1 is not limited to the above-mentioned fluorine coach ink, but may also be by pasting a fluororesin film. Alternatively, the detergent fall barrier 11 may be entirely made of fluororesin. In addition, 11 copies of Detergent Drop Prevention, 29
The specific structure for displacing and mixing the powdered detergent 42 from the detergent storage case 9, and the specific structure for displacing the powdered detergent 42 from the detergent storage case 9 are not limited to those described above, and as a whole, the It can also be applied to machines, etc., and can be modified and implemented as appropriate without departing from the gist. [Effects of the Invention] The present invention is as described above, and has the effects of -]4- above.
