Description

[Detailed Description of the Invention] This invention relates to a detergent dissolving device for a washing machine.

Since the problems of phosphorus pollution and human safety caused by synthetic detergents have become a focus of social attention, we have taken this opportunity to develop powdered soaps (hereinafter referred to as In this specification, this type of soap is simply referred to as "powder soap"). However, because powdered soap has poor solubility, it is inconvenient that it cannot be used as easily as synthetic detergents. That is, if soap is used in an undissolved state, undissolved soap particles will adhere to the laundry, and especially particles that have gotten into pockets or folded parts are difficult to remove. In addition, these soap particles adhere to the vicinity of the drain hole of the washing tub, causing mold and the like to grow. On the other hand, if used in excess, it will give the laundry a strange odor and yellowing.
For these reasons, soap powder is not very popular. In view of this point, several washing machines that are compatible with soap powder have been proposed. For example, there is a washing machine in which a small bowl-shaped container heated by a heater wire is installed near the top of the washing tub, and powdered soap is dissolved in lukewarm water in the container before being poured into the washing tub. According to this method, powdered soap can be dissolved well before use, but it takes time and effort to prepare lukewarm water, and in addition to requiring extra electrical energy for heating, It is structurally complex and undesirable in terms of cost.

Therefore, the purpose of this invention is to provide a detergent dissolving device that can efficiently dissolve powdered soap in a short time without requiring the user's time and effort.

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

FIG. 1 shows a typical two-tub washing machine having a washing tub 1 and a dehydration tub 2, and the detergent dissolving device according to this invention uses a pulsator installed at the bottom of the washing tub 1. A porous detergent storage container 4 is provided which is detachably attached to the fan 3 and rotates therewith. Referring to FIGS. 2 and 3, the container 4 has a container body 5 made of a cylindrical body with a bottom.
and a lid 7 pivotally attached to the opening of the container body 5 via a hinge 6 so as to be openable and closable. The container body 5 has a plurality of windows 8 bored at appropriate intervals in its peripheral wall, and these windows 8 are made of fine-mesh windows provided along the inner peripheral wall of the container body 5. It is covered with a mesh body 9 made of wire mesh or the like. In this case, as shown in FIG. 4, a guide blade 10 is formed on the side edge of the window 8 and is opened slightly outward from the tangential direction of the container body 5. The guide vanes 10 allow the washing water in the washing tub 1 to be effectively introduced into the container body 5 as the container 4 rotates. Further, a chuck member 11 for detachably attaching the container 4 to the pulsator fan 3 is provided at the center of the bottom wall of the container body 5. As illustrated in FIG. 5, this chuck member 11 is made of a metal cylinder and has a plurality of elastic claws 13 divided by slits 12 extending in the axial direction. The pulsator fan 3 may be fitted with an enlarged head of a tightening screw 14 located on the center of rotation of the pulsator fan 3 and fastening it to the fan drive shaft 19 (see FIG. 1). It is formed to do so. Therefore, this container 4 is coaxially attached to the pulsator fan 3 via the chuck member 11. In this regard, the lower periphery of the container body 5 is formed in a corrugated shape that matches the uneven surface of the pulsator fan 3. On the other hand, the lid body 7 is made of a cup made of transparent synthetic resin or the like, and this cup is provided with a scale line 20 for measuring detergent. A hook 16 is formed which cooperates with a notch hole 15 drilled near the opening of the container body 5. On the other hand, in this invention, when the container 4 is attached to the pulsator fan 3 and rotated together to dissolve the soap powder, undissolved soap particles move upward due to the centrifugal force, etc., and enter the lid body 7. In order to prevent it from entering and remaining inside, the container body 5
A partition plate 17 made of a ring-shaped disc member is provided in the opening.

Next, the operation of this detergent dissolving device will be explained. First, open the cup-shaped lid 7 and scoop powdered soap into it. In this case, since the lid 7 is provided with graduation lines 20, it is possible to easily measure the appropriate amount of soap powder. Then, the container body 5 is placed on the lid body 7, turned upside down, then returned to the upright position, and the chuck member 11 is forcibly pushed into and engaged with the tightening screw 14 of the pulsator fan 3. The container 4 is coaxially attached to the pulsator fan 3. Next, washing water is poured into the washing tub 1 to the extent that the container body 5 is submerged, and the pulsator fan 3 is rotated. As a result, the container 4 rotates at a speed of about 400 revolutions per minute together with the pulsator fan 3, so that a whirlpool of washing water flowing in through the window 8 and the mesh 9 is generated in the container 4, and the soap powder is washed away. It is vigorously stirred and dissolved in the washing water using a vortex. According to experiments, powdered soap could be almost completely dissolved within a range of about 1 to 2 minutes. Further, as shown by the imaginary line in FIG. 3, by inserting the ground powder wooden stick 18 into the container body 5, more effective dissolution can be achieved. In this way, a detergent solution in which powdered soap is almost completely dissolved is created in the washing tub 1. After that, put container 4 into pulsator fan 3.
The washing tub 1 is then removed, a predetermined amount of washing water is replenished into the washing tub 1, and washing is started. In addition, although the mesh body 9 is used in the above-mentioned embodiment, it is also possible to provide water permeation holes in the peripheral wall of the container body 5 that are substantially smaller in diameter than the particle size of the soap powder. Of course. Furthermore, instead of the chuck member 11, a mounting means having a male and female fitting structure may be used.

As is clear from the detailed explanation above, according to this invention, soap powder is stored in a net-shaped container, and this container is attached to a pulsator fan and rotated together with it, making it difficult to melt. Powdered soap, which was considered difficult to use, can be easily and almost completely dissolved in cold water in a short time. Therefore, this invention is useful for popularizing powdered soap, and also reduces the amount of powdered soap used. Furthermore, since the rotational force of the pulsator fan is utilized, it can be applied to existing washing machines as is without any design changes, making it extremely convenient.
