Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a negative ion generator.

[0002]

2. Description of the Related Art As is well known, negative ions, particularly when combined with water, have the effect of stabilizing the mind and relaxing the person. An apparatus for generating such ions is disclosed in, for example, Japanese Patent Laid-Open No. 11-265780. Thus, this device is provided with a tank for storing water, a heater for heating water to generate water vapor, and an air ion generator for generating air ions, and when the water vapor is combined with the air ions, It is designed to generate effective negative ions in the human body.

[0003]

However, in the above-mentioned negative ion generator, in order to effectively generate negative ions in the human body, water must be stored in the tank at all times, and at the time of use. Is an indispensable task that requires water supply. Therefore, an object of the present invention is to provide a negative ion generator that does not need to store water in a tank.

[0004]

To solve the above-mentioned problems, the first technical means taken in claim 1 is a water-drop generating device for converting water in the atmosphere into water drops by dew condensation, and evaporation of the water drops. An evaporation device for generating air ions, and an air ion generation device for generating air ions that combine with evaporated water generated by the evaporation, and generate negative ions when the air ions combine with the evaporated water generated by the evaporation. That is, the negative ion generating device is configured.

A second technical measure taken in claim 2 is that a single Peltier module constitutes the water drop generating device and the evaporation device.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a negative ion generator according to the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, a negative ion generator 1
0 includes a casing 14 in which a ventilation passage 12 extending in the horizontal direction is defined. A Peltier module 20 is arranged in the casing 14, and an outer surface portion 22 of the Peltier module 20 is exposed in the air passage 12. Peltier module 2
The inner surface portion 24 of 0 is cut off from the ventilation passage 12,
Fins 26 are provided. Peltier module 20
Is connected to a control device 30 whose main component is a microcomputer.

As is well known, the control device 30 switches the current-carrying characteristics to the Peltier module 20,
The outer surface portion 22 of the Peltier module 20 is brought into a low temperature state or a high temperature state. When the outer surface portion 22 of the Peltier module 20 is in a low temperature state, the inner surface portion 24 is in a high temperature state.
It is designed to be discharged to the outside. When the outer surface portion 22 of the Peltier module 20 is cold, dew condensation occurs,
Moisture in the atmosphere is solidified and a large number of water droplets 32 adhere to the outer surface portion 22. Then, when the energization characteristics to the Peltier module 20 are switched and the temperature of the outer surface portion 22 becomes high, the water droplets 32 evaporate and become water vapor.

An air ion generator 40 is housed in the casing 14, and its ionization needle 42 is exposed in the air passage 12 so as to be located upstream of the outer surface portion 22 of the Peltier module 20. When the air ion generator 40 is operated, the ionization needle 42 is discharged and air ions (minus ions) are generated on the upstream side of the air passage 12.

A blower fan 44 under the control of the control device 30 is disposed in the blower passage 12 so as to be located upstream of the ionization needle 42 of the air ion generator 40. Then, when the blower fan 44 is driven to send out the air ions (negative ions) generated by the discharge of the ionization needle 42 in the right direction (downstream side) in the drawing, the air ions (negative ions) are combined with the evaporated water. Then, it is discharged to the outside of the casing 14 as negative ions effective for the human body.

The operation of the negative ion generator 1 having the above structure will be described in time series as follows.

(1) When a main switch (not shown) is turned on, the controller 30 energizes the Peltier module 20 and drives the fans 28 and 44. At the same time, the air ion generator 40 operates. When the Peltier module 20 is energized, its outer surface portion 22 is cooled to the dew condensation temperature of the atmosphere, and water droplets 32 are formed on the outer surface portion 22.
Adheres. On the other hand, the inner surface portion 24 of the Peltier module 20 generates heat, and this heat is radiated by the fins 26 and discharged to the outside of the casing 14 by the fan 28.

(2) When the water droplets 32 attached to the surface of the outer surface portion 22 of the Peltier module 20 reach a predetermined amount (usually proportional to the energization time to the Peltier module 20), the control device 30 transfers to the Peltier module 20. The current conduction polarity is reversed so that heat is radiated from the outer surface portion 22. Due to this heat dissipation, the water droplets 32 attached to the surface of the outer surface portion 22 are evaporated.

(3) By operating the air ion generator 40, air ions (minus ions) are generated in the air passage 12, and the air ions (minus ions) are generated.
Is sent to the downstream side by the fan 44 and is combined with the water droplets 32 that have become steam, and negative ions that are effective for the human body are generated and discharged to the outside of the casing 14.

As shown in FIG. 2, the air ion generator 40 may be provided on the downstream side of the Peltier module 20.

[0016]

According to the first aspect of the present invention, since water is obtained from the atmosphere by dew condensation, it is not necessary to store water in the tank, and the simplification, downsizing and maintenance of the device accompanying the removal of the tank are achieved. Can be facilitated.

According to the second aspect of the present invention, dew condensation and evaporation can be performed by switching the energizing polarity of a single Peltier module, so that the apparatus itself and control can be simplified.
