Description

DETAILED DESCRIPTION OF THE INVENTION The present 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.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a detergent dissolving device that can efficiently dissolve soap powder in a short period of time without requiring the user's time and effort.

Hereinafter, embodiments of the present 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 a detergent dissolving device 4 according to the present invention is installed in an operation box 3 of the machine with a water inlet 29 and a water inlet 29. It is integrally incorporated so as to be located within the water supply path connecting to the washing tub 1. As shown in detail in FIGS. 2 and 3, the detergent dissolving device 4 includes a shroud 6 that is formed to protrude forward from the front panel 5 of the operation box 3. . This shroud 6 is integrated with the operation box 3 to form a predetermined compartment therein, and has a circular opening 7 on its top surface and an opening toward the washing tub 1 on its bottom surface 8. A hollow water inlet 9 is formed. Inside the shroud 6, there is a rotary impeller 10,
A water supply pipe 11 arranged in connection with this is provided. Referring to FIG. 4, the rotor wheel 10
A ring member 14 having a boss 13 provided at its center via a spoke member 12, a ring member 15 of the same diameter disposed opposite the ring member 14 at a predetermined distance, and a ring member 14 connected therebetween. multiple blades 16
The rotary wheel 10 includes a shroud 6
A support base 17 formed on the bottom surface 8 within the
It is rotatably supported via a screw 18 inserted into the boss 13. In this case, the rotor wheel 10 is oriented vertically and is provided directly below the opening 7 of the shroud 6.

The water supply pipe 11 has two branch pipes 19 and 20 branched into an L-shape, and one of the branch pipes 19 is
It is disposed on the side of the rotor wheel 10 so as to extend parallel to its axis, and the other branch pipe 20
are arranged so as to extend horizontally or slightly diagonally downward below the rotary impeller 10.
The branch pipe 19 is connected to the blades 16 of the rotor 10.
It is equipped with a slit-shaped nozzle hole 21 that injects water at a predetermined angle toward the branch pipe 20.
is equipped with a slit-shaped nozzle hole 22 that injects water from below to above the rotary impeller 10.
In this case, the water injection angle from the nozzle hole 21 is
When viewed from the branch pipe 19 side, it is preferable that the angle is approximately bisecting the angle of intersection between a straight line toward the center of the rotary impeller 10 and a tangent line.

The detergent dissolving device 4 also includes a cylindrical detergent storage container 23 into which detergent such as powdered soap is placed. This container 23 is porous, and as shown in FIG. It is composed of a peripheral wall 26 made of a fine stainless steel wire mesh, and a bottom wall 27 made of a very fine stainless wire wire stretched over the lower ring member 24. The container 23 is formed in a size that allows it to be tightly and removably inserted into the rotary impeller 10 with some friction, and has a transparent opening. A cover 28 made of synthetic resin is detachably attached. Note that, unlike this example, the container 2
The peripheral wall 26 and the bottom wall 27 of No. 3 may be made of a synthetic resin body having minute water permeable holes or a fine synthetic resin net body. However, if a weak synthetic resin net is used, a rod-shaped reinforcing member will be attached between the ring members 24 and 25 in order to maintain it in a cylindrical shape. On the other hand, the size and mesh size of the through holes are such that detergents such as powdered soap cannot pass through them undissolved. Additionally, a fixing device such as an elastic hook may be provided between the rotary wheel 10 and the container 23, and the container 23 may be firmly fixed within the rotary wheel 10 by this fixing device. Of course. In FIG. 2, a reference numeral 30 indicates whether water introduced from a water supply source, ie, a water supply faucet, through a water supply inlet 29 is supplied to the washing tub 1 at the top or bottom, or to the dehydration tank 2. In this embodiment, when the switching lever 30 is switched to the upper water supply, water comes out from the water supply pipe 11 described above.

Next, the operation of this invention will be explained. First, an appropriate amount of soap powder is put into the container 23, a cover 28 is attached to the opening thereof, and then the container 23 is set into the rotary impeller 10 from above through the opening 7 of the shroud 6. When the water supply switching lever 30 is operated to switch to upper water supply, the water supplied through the water supply inlet 29 is guided into the water supply pipe 11 and connected to each branch pipe 1.
The water is vigorously jetted from the nozzle holes 21 and 22 of the nozzle holes 9 and 20, and the water jetted from the nozzle holes 21 causes the container 23 to rotate together with the rotary impeller 10. In this way, inside the rotating container 23, the soap powder is vigorously stirred and mixed with water that is blown in through the peripheral wall 26 and the bottom wall 27 made of wire mesh, creating a detergent liquid in which the soap powder is almost completely dissolved. .
Then, this detergent liquid is scattered out of the container from inside the rotating container 23 through the wire mesh of the peripheral wall 26 and the bottom wall 27 due to its centrifugal force, etc., and then flows through the water inlet 9 in the lower part of the shroud 6. and is poured into the washing tub 1. In this case, the undissolved grains get caught in the mesh of the wire mesh and are rarely discharged from the container, but these grains are eventually dissolved and disappear from the container 23 due to the vigorous stirring action. In this regard, since the cover 28 is made of transparent synthetic resin, it is possible to observe the state of dissolution of the soap powder through the cover 28. In other words, at first, the soap powder appears cloudy due to the foam, but as the dissolution progresses, the turbidity gradually disappears, and when all that remains is clear water, it is clear that the soap powder has been almost completely dissolved. can.

In addition, in the above embodiment, the container 23 is held and rotated within the rotary impeller 10, but
A blade may be provided on the peripheral wall of the container 23, and the container 23 itself may be rotatably mounted directly within the shroud 6, and soap powder may be placed into the container using a measuring cup or the like. Note that even in this case, the blades are optionally provided, and the present invention is not limited to the presence or absence of the blades.

As is clear from the description of the embodiments described above, according to the present invention, soap powder is placed in a porous cylindrical container made of a mesh or the like, and the container is directed from the water supply port of the washing machine to the washing tub. By rotating the soap in the water supply path under the pressure of water ejected through it, it is possible to almost completely dissolve powdered soap, which has been considered difficult to use, in cold water without preparing lukewarm water. In this case, the soap powder is sufficiently dissolved during the water supply process to collect the required amount of water in the washing tub, so no special operation time is required for dissolving it, which is extremely convenient for the user. be. Therefore, this invention greatly contributes to the popularization of powdered soap, and also reduces the amount of powdered soap used. On the other hand, since the container is simply rotated by the jet pressure of water passing through the water supply path, rather than by a rotary drive device such as a motor, the structure is simple and has advantages in terms of cost and energy saving. You can get a lot of benefits. On the other hand, according to the present invention, since the container is installed vertically, it is convenient to handle when putting detergent such as powdered soap into the container. In addition, in connection with this vertical installation, the bottom wall of the container is also made of a porous material such as wire mesh, and since water is sprayed from below against this bottom wall, the soap powder inside the container is The stirring and dissolution of the soap is further accelerated, and there is no risk of the soap powder becoming sticky on the bottom wall, and a high dissolving power can be obtained.
