2. Description of the Related Art Ultrasonic cleaning is known as one means for cleaning and has been applied to the above-mentioned precision equipment parts and the like. The outline thereof is a vibration of piezoelectric ceramics or the like exposed to a cleaning tank made of metal or resin. The child is formed into a spherical type, a disc type, a square type, etc.
This is operated to generate ultrasonic waves, and the cleaning action based on the ultrasonic vibrations removes dirt and enhances the cleaning effect.

[0004]

However, these conventional ultrasonic cleaners tend to lack the power density, and have been devised in a spherical or cylindrical shape for focusing, but they are still insufficient. Therefore, there is a drawback that the cleaning power is insufficient, or conversely, if the cleaning power is to be increased, the momentum device becomes large in size, and a considerable amount of electric power is required. The present invention has been made to solve these drawbacks.

[0005]

A cleaning device of the present invention is provided with a vibrator for generating ultrasonic waves facing a cleaning tank, and
Characterized by arranging a far-infrared radiation ceramics for finely dividing water molecule clusters toward a region near where ultrasonic waves from the oscillator are focused, and further facing an ozone generator having a bactericidal action Composed.

[0006]

The ultrasonic wave generated from the vibrator causes cavitation in the cleaning liquid in the cleaning tank, and the vibration and peeling action cause the contaminants to be desorbed from the adherend. At this time, the contaminants are emitted from the ceramics. Far-infrared rays make clusters of water molecules finer and vibrate due to the cavitation,
In cooperation with the peeling action, it penetrates into the adsorption interface between the adherend and the dirt substance, promotes desorption of dirt, and improves cleaning efficiency.
When bacteria or the like are present, the sterilizing effect of ozone is amplified by far infrared rays to keep clothes and the like clean.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings, in which 1 is a washing machine having a washing tank 2 arranged therein, and the washing tank 2 is made of metal or synthetic resin, and is a household washing machine. The volume, shape, etc. are determined according to the application of precision equipment parts, IC boards, etc.

Then, a vibrator 3 for generating an ultrasonic wave is made to face a part of the cleaning tank 2, and the vibrator 3 is, for example, P.
A ZT (zircon / lead titanate) ferroelectric piezoelectric element is sandwiched between electrodes and connected to an oscillation circuit. At this time, the power density of ultrasonic waves exceeds atmospheric pressure,
Set the value required to cause cavitation. The power density (I) is expressed by the following equation: I = p ² / ρ ₀ c (W / m ² ) p: Sound pressure (N / m ² ) ρ ₀ : Atmospheric density without sound (Kg / M ³ ) c: Propagation velocity of sound waves (m / s) Usually, the atmospheric pressure is 1 atm, so about 0.35 × 10 ⁴
Set to a power of W / m ² or more.

Since it is desirable to focus the ultrasonic wave on the target adherend, a shape such as a spherical shape, a circular shape, or a cylindrical shape is focused according to the position and size of the adherend.

Next, 4 is a ceramic which emits far-infrared rays, and is provided with a radiation characteristic capable of miniaturizing water molecule clusters as much as possible. That is, far-infrared light refers to infrared light having a wavelength of 3 to 4 μm or more. When the radiation wave is applied to water molecules, the vibration frequency of water molecules out of the natural frequency of water molecules and the frequency of far-infrared light. Those that match the number are absorbed, causing resonance absorption. This resonance absorption acts on a chain of clusters formed by connecting several water molecules by hydrogen bonds, and has a force of refining into water molecules of smaller clusters. Therefore, it is intended to induce more effective cleaning action against the cavitation by ultrasonic waves by using the water molecules around the cavitation as fine cluster molecules. As the far-infrared radiation ceramics, ceramics containing fired white porcelain powder and alumina powder as main components and powders of ferrous oxide, silicon carbide, carbon, magnesia, and silica added thereto can be used.

Further, 5 is an ozone generator, which introduces air into the vessel and applies a high voltage electric field to the air, or radiates ultraviolet rays to convert oxygen in the air into ozone. The generated ozone is supplied into the cleaning tank 2. The ozone is used to promote sterilization and bleaching action when bacteria are attached to the adherend or when it is desired to make the laundry whiter.Far infrared rays have the property of increasing the amount of dissolved oxygen. It is used with the aim of increasing the sterilization and bleaching action from the increase of the amount of bleach.

Next, the operation of the present embodiment will be described. Into the main cleaning tank 2, a cleaning material to which the desired dirt is attached is put and the vibrator 3 for generating ultrasonic waves is operated. Then,
When the atmospheric pressure is 1 atm, a sound pressure of 1 atm or more is generated at a power of 0.35 × 10 ⁴ W / m ^{2, and} a vacuum state is generated by a negative pressure at a half-cycle shift, By repeating this, the dirt substance adhering to the washed product receives the force of suction and peeling, and the desorption action is promoted.

At this time, the interface between the adhered substance and the dirt substance is initially adsorbed, but when suction and peeling are repeated, water molecules permeate into the interface, weakening the adsorption force of the interface and desorbing. Encourage. Further, since far infrared rays are radiated from the ceramics and the surrounding water is miniaturized into smaller clusters, it easily enters the gap between the adherend and the dirt substance, and a slight gap is generated by the cavitation. Even if
The water molecules directly infiltrate and act to separate the interface and make the cleaning more effective by desorption. Also, the action of cavitation and clusters of water molecules disturbs and defoams the cleaning solution,
It is also effective for emulsification, and from this aspect also improves the cleaning effect.

Further, bacteria and the like are easily propagated on clothes and tableware, and when oil adheres to precision instruments, bacteria are often propagated by using it as a nutrient source. In that case, the ozone generator 5 is used. The released ozone is dissolved in water, and its strong oxidizing power exerts a bactericidal action, so that the washed product can be made aseptic and hygienic. At that time, the cluster by far infrared
Has a property of increasing the amount of dissolved oxygen, and amplifies the bactericidal action. Also, because it also exerts a bleaching action,
It is also effective when you want to wash your clothes white.

[0015]

The present invention based on the above configuration and operation is
The performance of the conventional ultrasonic cleaner can be further improved, the cleaning effect can be made more effective, and since it does not increase the size of the device or increase the power consumption, it is extremely labor-saving. Produce an effect. In addition, it is possible to reduce the amount of detergent or freon used for clothing, tableware, and equipment parts, or to improve the washing effect sufficiently without using it, so that the river and ocean are contaminated by the detergent. , And can be expected to help eliminate air pollution caused by CFCs.
