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 dehydrating tub 2, and its operation box 3 is equipped with a detergent dissolving device 5 according to this invention. The detergent dissolving device 5 is integrally incorporated so as to be located within the water supply path connecting the water supply inlet 4 and the washing tub 1. As shown in detail in FIGS. 2 and 3, the detergent dissolving device 5 includes a housing 7 formed to protrude in front of a front panel 6 of the operation box 3. This housing 7
forms a predetermined space between it and the bottom surface 8 of the operation box 3, a circular opening 9 is provided on the top surface, and a water inlet 10 that opens toward the washing tub 1 is provided on the bottom surface 8. It is formed. A circular ring-shaped pedestal 12 with legs 11 is provided on the bottom surface 8, and a cylindrical detergent storage formed of an extremely fine stainless steel net 13 is placed on the pedestal 12. A container 14 is configured to be removably placed through the opening 9 of the housing 7. A ring-shaped gasket 15 is attached to the opening of the container 14, and a circular lid 16 is detachably and watertightly attached via the gasket 15. As shown in FIG. 4, this lid body 16 includes a frame 17 that is expanded into a flap shape, and a gasket 1 of the container 14 is provided at the front opening of the frame 17.
5 is provided with a rib 18 of a size that fits appropriately on the inner periphery of the frame 17, while a water supply port 19 on the back side of the frame 17 is
It is connected to a bellows-shaped hose 20 that communicates with the water supply path. A plurality of supporting members 21 are provided inside the lid body 16 and extend from the inner wall of the frame 17 toward just below the water supply port 19. In the embodiment, four blades 23 are rotatably mounted. This blade 23 has a pair of ring members 2
4 and 25, and a plurality of stirring blades 26 connected between them, a cage-shaped stirring body is coaxially attached. Therefore, these stirring blades 26
rotates within the container 14 together with the blades 23. On the other hand, the hose 20 extends into the interior of the operation box 3 through a hole 27 provided in the upper wall of the operation box 3, and its end is connected to the water supply inlet 4 via a water supply switch (not shown). It's communicating. This water supply switching switch is operated by a water supply switching lever 28 shown in FIG. Switched to dehydrated water supply.
When this lever 28 is switched to upper water supply, water is supplied into the container 14 via the hose 20.

Next, the operation of this invention will be explained. First, put an appropriate amount of soap powder into the container 14, and
is inserted into the housing 7 through the opening 9 and placed on the pedestal 12. Then, the lid 16 is placed on the container 14 so that the stirring blade 26 enters into the container 14, and the rib 18 is fitted into the packing 15 of the container 14. In this state, when the lever 28 is switched to the upper water supply, water introduced from the water supply faucet as the water supply source through the water supply inlet 4 is supplied into the container 14 from the water supply port 19 through the hose 20. In this case, the water hits the blades 23 and is diffused and sprayed while rotating the stirring blades 26 together with the blades 23. Therefore, the powdered soap is exposed to the jetted water and is stirred by the stirring blade 26, so that it is effectively dissolved.
The soap solution thus produced flows out through the fine water permeable holes of the net 13 and is supplied into the washing tub 1 through the water inlet 10.

Next, FIG. 5 shows a second embodiment. According to this, the cage-shaped stirring body consisting of the blades 23 and the stirring blades 26 that are coaxially connected to each other includes a thrust bearing 30 provided at the center of the bottom wall of the container 14 and a vertical shaft that cooperates with the thrust bearing 30. It is rotatably supported within the container 14 via 29.
Further, an arm 31 extending in the horizontal direction is formed on the outer surface of the lid body 16, and the tip of this arm 31 is rotatably screwed to a support piece 32 installed around the opening 9 of the housing 7. has been done. According to this second embodiment, unlike the previously described embodiments, the blades 23 and the stirring body are provided on the side of the container 14, so that the lid 16 can be easily attached to and removed from the container 14. In addition, in these embodiments, a plurality of brushes may be attached instead of the stirring blades 26.

Moreover, FIG. 6 shows yet another example. This includes a semi-cylindrical detergent storage container 14' made of a mesh body 13, and a semi-cylindrical lid body 16' that is almost the same as the detergent storage container 14'.
6', one side of these openings is connected by a hinge (not shown), so that the lid body 16' can be opened and closed. A rotary impeller 34 is attached to the inside of the lid 16' via a rotating shaft 33 supported by both side walls thereof. In addition, the lid body 1
A water supply pipe 35 is connected to the upper center of the lid body 16', and this water supply pipe 35 is opened in the tangential direction on the inner surface of the lid body 16'.
It is designed to spout water towards its wings.
Therefore, the rotary impeller 34 is rotated by the water jetted from the water supply pipe 35, and thereby the detergent is strongly stirred and dissolved.

In addition, in each of the above embodiments, the containers 14, 1
The material of 4' is not limited to the net body 13, but may be a synthetic resin plate having fine water permeable holes. Further, in any case, the water permeation holes preferably have dimensions such that detergent particles cannot pass through them undissolved.

As is clear from the description of the embodiments described above, according to this invention, a porous detergent storage container made of a net or the like is provided in the water supply path connecting the water supply inlet of the washing machine and the washing tub. By arranging an agitator such as a rotary impeller inside the container and rotating the agitator by spouting the water passing through the water supply path into the container, powdered soap, which was previously considered difficult to use, can be turned into cold water. can be almost completely dissolved. Therefore, undissolved soap particles are prevented from adhering to the laundry or near the drain hole of the washing tub, which can greatly contribute to the spread of powdered soap. Moreover, since powdered soap is dissolved in a series of water supply processes in which the required amount of washing water is stored in the washing tub via the water supply path, special operations for dissolution such as preparing lukewarm water in advance as in the conventional method are not required. It is extremely convenient and does not require much time. On the other hand, since it simply utilizes the jet of water supplied to the washing tub without using any other driving device, it is advantageous in terms of structure and cost.
