Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a method for washing laundry in ordinary households.

[0002]

2. Description of the Related Art A conventional method for washing laundry will be described below. In general, most conventional washing methods for washing laundry in homes are agitation washing with a washing machine, except for some delicate clothes. FIG. 3 shows a stirring cleaning method which has been conventionally generally used at home. In FIG. 3, reference numeral 1 is a washing tub in which laundry and a washing liquid are put. Reference numeral 2 is a stirring mechanism for stirring the laundry and the cleaning liquid. The operation of the stirring and cleaning method having the above configuration will be described below. Put the laundry and washing liquid in the washing tub. When the agitating mechanism of 2 is operated, the laundry and the washing liquid in the laundry tub of 1 are agitated, and the laundry is washed.

[0003]

However, the above-mentioned conventional cleaning method has the following problems.
That is, the laundry is agitated in the washing liquid in the washing tub by the agitating mechanism, and the dirt is removed by the effect of the washing liquid and the rubbing and twisting of the laundry. However, since the laundry itself is damaged by rubbing and rubbing between the laundry at the same time as the stains are removed, it is not suitable for washing delicate cloth or woolen products.

The present invention solves the above-mentioned conventional problems. Since the laundry is not damaged by agitation, it cannot be washed by the agitation washing method of a conventional washing machine or the like, and washing of delicate clothes, etc., which has been done by hand washing, is performed. It is an object of the present invention to provide a cleaning method capable of cleaning objects. In addition, since it is possible to perform washing with a stirring force smaller than that of the conventional method when used in combination with the stirring washing method, it is an object of the present invention to provide a washing method that is less likely to damage the laundry due to stirring and has a strong washing force.

[0005]

In order to achieve the above object, the first aspect of the present invention provides a method for washing laundry, wherein a magnetic force is applied to the laundry and the washing liquid by an electromagnetic coil.

In addition, in the second aspect of the present invention, in addition to the conventional stirring and washing, there is provided a washing method for laundry, in which a magnetic force is applied to the laundry and the washing liquid by an electromagnetic coil.

[0007]

According to the first means, a magnetic force is generated by providing an electromagnetic coil and applying a voltage. The magnetic force acts on the washing liquid and the laundry to wash the laundry without moving it. That is, the laundry can be washed without damaging it. According to the second means, in addition to the conventional stirring and washing method, an electromagnetic coil is provided to apply a magnetic force to the laundry and the washing liquid, and the magnetic force acts on the washing liquid and the laundry to wash the laundry. Washing can be performed with less stirring power, damage to the laundry due to stirring is less likely to occur, and strong cleaning power can be provided.

[0008]

EXAMPLE An example of the first means will be described below with reference to FIG. In the figure, 3 is a washing tub for containing a cloth and a cleaning liquid. In the figure, 4 is an electromagnetic coil that applies a magnetic force to the washing liquid and the laundry. The operation of this embodiment will be described below with reference to FIG. Put the laundry and the washing liquid in the washing tub of 3. When a voltage is applied to the electromagnetic coil 4 provided in the washing tub 3, a magnetic force is generated, which acts on the washing liquid and the laundry in the washing tub 3 to wash the laundry. As described above, according to the present embodiment, by applying a magnetic force to the laundry and the cleaning liquid by the electromagnetic coil, it is possible to wash the laundry without damaging it.

The results of a cleaning experiment using an electromagnetic coil will be described below. The experimental conditions and methods are as follows. (Conditions) Detergent used: Kao Attack Detergent concentration: 0.83
g / l Contaminated cloth used: Lion wet contaminated cloth 5 sheets / detergent liquid 1l Water temperature: 24 ° C Reflectance measurement: photoelectric reflectometer Electromagnetic coil: National electromagnetic cooker KZ-20DT (method) Detergent liquid on energized electromagnetic coil Place a beaker containing 1 liter, and soak the contaminated cloth in it for 30 minutes to wash it. As a standard condition, soak and wash without electromagnetic coil, and compare the cleaning effect. The cleaning effect depends on the cleaning degree obtained from the measured value of the photoelectric reflectometer. (Result) With the use of the electromagnetic coil, the cleaning degree was improved by about 34% over the standard condition.

An embodiment of the second means will be described below. 2 is used as a reference diagram. In the figure, 5 is a washing tub for containing cloth and cleaning liquid. In the figure, 6 is an electromagnetic coil that applies a magnetic force to the washing liquid and the laundry. In the figure, 7 is a stirring mechanism for stirring the cloth and the washing liquid in the washing tub.

The operation of this embodiment will be described below with reference to FIG. The laundry and the washing liquid are put in the washing tub 5 and the washing mechanism and the washing liquid in the washing tub 5 are stirred and washed by the stirring mechanism 7. At this time, when a voltage is applied to the electromagnetic coil 6 at the same time, a magnetic force is generated, which acts on the washing liquid in the washing tub 5 and the laundry, and a stronger washing force is applied to the laundry. As described above, according to the present embodiment, in addition to the conventional stirring and washing method, by applying a magnetic force to the washing liquid by the electromagnetic coil, the magnetic force acts on the washing liquid and the laundry to wash the laundry,
Washing can be performed with a smaller stirring force than before, damage of laundry due to stirring is unlikely to occur, and strong washing power can be provided.

[0012]

As is apparent from the above description, according to the first means of the present invention, a magnetic force is applied to the washing liquid by the electromagnetic coil, and the magnetic force acts on the washing liquid and the laundry to wash the laundry. Can be washed without moving. That is, washing can be performed without damaging the laundry due to rubbing or entanglement between the laundry. According to the second means, in addition to the conventional stirring and washing method, by applying a magnetic force to the washing liquid by using an electromagnetic coil, the lines of magnetic force act on the washing liquid and the laundry, and washing can be performed with less stirring force than the conventional method. The laundry is less likely to be damaged by the above, and a strong washing power can be given.
