Abstract

PURPOSE:To improve purifying efficiency by allowing the water sprayed from a spraying nozzle to collide against a collision plate to form finer water drops, thereby increasing the surface areas of the water drops and causing the easier evaporation of the low boiling materials, for example, trihalomethane, in the water drops. CONSTITUTION:The collision plate 3 is provided in the spraying direction of the spraying nozzle 1. A cylindrical water collecting cover 2 and a water receiving container 9 are installed circumferentially by providing a vent space 10. The collision plate which is fixed or is applied with vibrations by a vibrator is adopted for the collision plate 3. The vibration frequencies of the collision plate 3 are regulated by the degree of fining. The water sprayed from the spraying nozzle generates the flow of air by including the ambient air therein by its viscosity. A part of the low boiling materials contained in the water are simultaneously evaporated into the ambient air during the movement to the collision plate 3. The water thereafter collides against the collision plate 3 and the additionally finer water drops are formed and dissipate into the ambient air, by which the remaining low boiling materials are evaporated.

Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention relates to a water purifier that purifies water by spraying.

[0002]

2. Description of the Related Art In the prior art, as shown in FIG. 3, water sprayed from a spray nozzle 1 and freed from volatile harmful substances such as trihalomethane is collected by a water collecting cover 2 and a water receiving container 9 and discharged at the bottom. It is drawn from the water spout 8 with a cup 11 or the like and used for drinking or the like. However, in this method, the state of the spray water cannot be said to be very fine, and therefore, there is a drawback that low boiling point substances (for example, trihalomethane etc.) contained in water cannot be sufficiently removed.

Further, there is a drawback in that the removal rate becomes so low that a predetermined removal rate cannot be obtained particularly when the apparatus is downsized.

[0004]

In view of the above-mentioned drawbacks of the prior art, the present invention aims to improve the efficiency of spray purification.

[0005]

SUMMARY OF THE INVENTION The gist of the present invention is a water purifier characterized in that sprayed water droplets collide with a collision plate 3.

[0006] The atomized water is collided with the collision plate 3 to make the particles finer. The collision plate 3 may be in a fixed state or may be vibrated by a vibrator. The frequency when vibrating the collision plate 3 needs to be adjusted depending on the degree of miniaturization to be achieved.
For example, the fineness (particle size 100 to 500 microns) for removing trihalomethane is about several kilohertz to 10 kilohertz. Further, when a substance that is less likely to be volatilized is targeted, it is necessary to increase the frequency.

[0007]

[Operation] The water sprayed from the spray nozzle collides with the collision plate, and the collision causes water droplets to become finer. The miniaturization increases the surface area of the water droplets, the low boiling point substances in water are easily evaporated, and the purification efficiency is increased.

Further, when the collision plate vibrates, the water droplets collide with the vibrating collision plate, which is further miniaturized as compared with the case where the collision plate collides with a fixed collision plate. The Rukoto.

[0009]

The present invention will be described with reference to the drawings.

FIG. 1 shows a first embodiment. The overall configuration is such that a collision plate 3 is provided in the spray direction of the spray nozzle 1 and a cylindrical water collecting cover 2 and a water receiving container 9 are provided around the collision plate 3 with a ventilation space 10 provided.

The water sprayed from the spray nozzle 1 engulfs ambient air due to its viscosity and produces a flow of air as shown by an arrow in the figure. At the same time, while moving to the collision plate 3, a part of the low boiling point substance contained therein is volatilized to the ambient air. After that, the water droplets collide with the collision plate 3 and the water droplets are further miniaturized and scattered into the surrounding air, and the rest of the low boiling point substance is vaporized. After that, the low-boiling substance that has volatilized is entrained in the air flow and is discharged to the outside via the ventilation space 10. At the same time, the purified water is received from the outlet 8 by the lower cup 11 or the like so as to be used for drinking or the like.

FIG. 2 shows a second embodiment, which is basically the same as the first embodiment, except that the collision plate 3 is composed of a vibrator, and the transmission circuit 7 is used for the collision plate 3. It enables to control the frequency of, and facilitates the removal of specific low boiling point substances.

[0013]

EFFECTS OF THE INVENTION According to the water purifier of the present invention, since the sprayed water collides with the collision plate to be atomized, the surface area increases, and as a result, low-boiling substances such as trihalomethane in water are volatilized. It becomes easier and the efficiency of purification is improved.

Further, even if the apparatus is downsized, the removal rate does not decrease and a predetermined removal rate can be obtained.
