DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing apparatus suitable for washing stubborn stains on textiles such as clothes and socks, and a method for washing textiles using the washing apparatus.

[0002]

2. Description of the Related Art Conventionally, stubborn dirt attached to textiles such as clothes and socks, for example, sebum dirt, mud dirt, oil dirt,
To remove dirt from foods and drinks such as soy sauce and curry, and dirt from blood adherence due to injuries, apply a cleaning solution such as a detergent directly to the dirt on the object to be cleaned in advance, and then print with a hand fir, brush, sponge, etc. Methods such as sweeping or immersing the object to be washed in a washing solution and then washing with a washing machine are used.However, in these methods, the hands are rough, the object to be washed is damaged, There was a problem that a good cleaning effect could not be obtained.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and a cleaning apparatus capable of efficiently cleaning stubborn dirt attached to textiles, and a cleaning apparatus for cleaning the same. It is an object of the present invention to provide a method for cleaning textile products using the apparatus.

[0004]

In order to achieve the above object, a cleaning apparatus according to the present invention comprises a head for mounting a cleaning brush, and a grip following the head. Cam ratio 1: 1.5 to 1: 5, vibration frequency 3
A housing with a motor having an eccentric cam driven at 0 to 400 Hz and a vibration amplitude of 20 to 2000 μm is accommodated, and a battery serving as a driving power source for driving the motor with the eccentric cam is housed in the grip portion. The cleaning brush is mounted on a front end opening surface of a head portion accommodating a motor. It is preferable that the grip and the head are connected via a buffer made of an elastic material for sound and vibration proof.

[0005] A cleaning method according to the present invention is a method for cleaning textiles using the cleaning apparatus according to the present invention, wherein the HLB 7-1 is used when cleaning textiles using the cleaning apparatus.
The textile product is washed by adhering a cleaning liquid containing 0.05 to 60% of the nonionic surfactant of No. 5 to a brush of the cleaning device.

When a textile product is cleaned using the cleaning device having the above-described structure, the entire cleaning device vibrates at a predetermined vibration frequency due to the eccentric rotation of the eccentric cam rotated by the motor, and the brush tip to which the cleaning liquid has adhered. Hits the fiber surface repeatedly at high speed. For this reason, the fine particles and components of the dirt strongly adhered between the fibers also rise from the fiber surface and are scraped off by the brush, so that a strong cleaning effect is exhibited.

As a result, stubborn, hard-to-remove dirt and the like that have entered between fibers can be reliably washed without damaging the fibers. Also, it is only necessary to hold the grip of the cleaning device by hand and lightly press the tip of the brush with the cleaning liquid against the textile, so that the hand does not get wet with water or the cleaning liquid and becomes rough and eccentric. Since the dirt is scraped off by an appropriate vibration force by the motor with the cam, the textiles are not damaged, and the textiles can be easily and reliably washed.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show a cleaning apparatus according to a first embodiment of the present invention. FIG. 1 is a central longitudinal sectional view of the cleaning apparatus according to the first embodiment, FIG. 2 is an exploded perspective view, FIG. 3 is a perspective view showing the overall shape, and FIG. 4 is a front view of an eccentric cam.

In FIG. 1, reference numeral 1 denotes a main body case made of plastic or metal. In the case of the illustrated example, the main body case 1 is configured in a flashlight-like shape,
The base end portion is a grip portion 1a for holding the device, and the tip end portion is a head portion 1b for storing and attaching a motor 2 with an eccentric cam and a brush 3 to be described later.
It has been.

The grip portion 1a has a battery compartment 1c inside.
In this battery chamber 1c, a dry battery 4 serving as a drive power source for a motor 2 with an eccentric cam described later is provided with positive and negative electrodes 1
It is stored in contact with d and 1e, and is covered with a cap 1f.

The head portion 1b has a motor housing chamber 5 having a predetermined size with an open end, in which a motor 2 with an eccentric cam for vibration is mounted. The detachable brush 3 is replaceably fitted in the opening.

As shown in the figure, the motor 2 with the eccentric cam has an eccentric cam 6 attached to the motor shaft 2a. When the motor 2 is rotated at a predetermined speed by using the dry battery 4 as a driving source, the motor 2 is rotated. The eccentric cam 6 rotates eccentrically, and the eccentric rotation causes the case body 1 including the brush 3 to rotate.
Are reciprocatingly vibrated at a predetermined frequency. The electric wiring and the power switch connecting the battery 4 and the motor 2 are not shown.

As shown in FIG. 4, the eccentric cam 6 is formed of a circular metal disk having a predetermined thickness, and is located at a predetermined distance A from the center O of the circular metal disk. An eccentric cam is formed by attaching the motor shaft 2a to the eccentric cam. In the case of a hand-held cleaning device that can be held by hand, the diameter of the eccentric cam 6 is preferably 9 to 12 mm. If it is less than 5 mm, the vibration amplitude is too small to exhibit a sufficient cleaning effect. If it exceeds 15 mm, the motor 2 will be overloaded and the life of the motor will be shortened.

The eccentric cam ratio A: B of the eccentric cam 6 is in the range of 1: 1.5 to 1: 5, preferably 1: 2 to 1: 4. If the eccentric cam ratio is less than 1: 1.5, the excitation force is too small, and it is difficult to obtain a sufficient vibration amplitude. If the eccentric cam ratio exceeds 1: 5, unpleasant noise due to eccentric rotation is generated. It becomes too large, which is not desirable.

In the illustrated example, the brush 3 is configured by implanting a plurality of bristle bundles 7 each of which is a bundle of a plurality of brushes (monofilaments) on a flocked surface of the brush surface. The brush 3 is detachably attached to the opening at the tip end of the head portion 1b by means of fitting in a concave and convex manner so as to be replaceable with another type of brush described later.

The vibration frequency of the brush 3 suitable for cleaning is 30.
The frequency is desirably set to 400 Hz, preferably 100 to 250 Hz. If it is lower than 30 Hz, the effect of removing dirt is small, and if it is higher than 400 Hz, the fibers are easily damaged. The number of rotations of the motor 2 for giving a vibration frequency of 30 to 300 Hz to the brush 3 is 1800 to 24000.
rpm, and the number of revolutions of the motor 2 for giving a vibration frequency of 100 to 250 Hz is 6000 to 15000 rpm.
It is.

The vibration amplitude of the brush 3 along the longitudinal direction of the main body case 1 is 20 to 2000 μm, preferably 3 to 20 μm.
0 to 1500 μm. When the vibration amplitude is smaller than 20 μm, there is almost no effect of removing dirt attached to the fiber, and when it exceeds 2000 μm, vibration is transmitted to the hand and the usability deteriorates.

Further, the waist strength of the hair bundle 7 is 2 to 30 kg.
· F / cm ² , preferably 5 to 20 kg · f / cm ² . When the weight is less than ² kg · f / cm ² , the hair is too weak to improve the washing effect, and when it exceeds 30 kg · f / cm ² , the hair is too strong and the fibers are easily damaged.

Washing of textiles such as clothes and socks using the washing apparatus is performed as follows. That is, first, a cleaning liquid suitable for a textile to be cleaned is prepared, and the hair bundle 7 of the brush 3 of the cleaning device is immersed in the cleaning liquid, so that the hair bundle 7 contains the cleaning liquid. Further, if necessary, the stained portion of the textile product to be cleaned is also immersed in the cleaning liquid and wetted.

Then, the tip of the hair bundle 7 containing the cleaning liquid is lightly pressed against the soiled portion of the textile, and in this state, the power switch (not shown) of the cleaning device is turned on. Accordingly, the motor 2 starts rotating at a predetermined speed, and accordingly, the eccentric cam 6 fixed to the motor shaft 2a starts eccentric rotation.

When the eccentric cam 6 starts eccentric rotation, the entire cleaning device starts vibrating at a predetermined vibration frequency by the eccentric rotation force, and the tip of the hair bundle 7 hits the fiber surface at a high speed. The hair tips penetrate not only between the yarns constituting the cloth, but also between the fibers constituting the yarns, and directly brush the fibers themselves.

As a result, the fine particles and components of the dirt that have entered between the fibers and strongly adhered thereto are also lifted off the fiber surface and are scraped off. Therefore, a strong cleaning effect is exhibited, and the stubborn penetrated between the fibers and hardly falls off. Dirt can be reliably washed without damaging the fibers.

The cleaning liquid used for cleaning varies depending on the type of dirt.
The most effective cleaning can be carried out by using a cleaning solution containing 0.05 to 60%, preferably 10 to 45% of the nonionic surfactant of 15 to 15%. Three examples of such a cleaning liquid are shown below.

It is formed of a bellows-shaped cylinder made of an elastic material such as rubber, urethane, or elastomer, and has a grip portion 1a and a head portion 1b connected to each other via the bellows-shaped buffer portion 8.

As described above, the grip portion 1a and the head portion 1b
When the buffer portion 8 is provided between the two, the vibration accompanying the rotation of the motor 2 with the eccentric cam is absorbed by the buffer portion 8 and is not transmitted to the grip portion 1a. For this reason, the hand which grips the grip part 1a is numb by vibration and cannot be firmly grasped, and the operation of a washing apparatus can be made safer and more reliable. In addition, since only the head portion 1b vibrates without vibrating the entire cleaning device, the generation of noise due to the vibration is reduced.

In the case of the second embodiment, the vibration frequency of the brush 2 is 30 to 400 Hz, preferably 50 to 25 Hz.
It is desirable to set it to 0 Hz. The vibration amplitude of the brush 2 along the longitudinal direction of the main body case 1 is 20 to 2000 μm.
m, preferably 30 to 1500 μm.

The size of the eccentric cam 6, the strength of the hair bundle 7 and the like are the same as those in the first embodiment. The method for cleaning textiles using the cleaning apparatus according to the second embodiment is the same as that in the first embodiment, and a description thereof will be omitted.

In the above-described first and second embodiments, the brush 3 in which the bristle bundle 7 is planted is used. However, the present invention is not limited to this. For example, according to FIGS.
Can be used by replacing it with a brush as shown in FIG.
(A) is an example of a brush 3 composed of a loop flocked body 9 in which a loop 9a having a height of about 2 mm made of a synthetic fiber such as nylon is planted on the entire surface of a base cloth 9b, and (b) is a surface having a diameter of 2 m.
