2. Description of the Related Art A technique for cleaning indoor air by washing dirty air in a room with water and releasing negative ions generated by the Leonard effect due to the splitting of water droplets into the room to purify the room air has been known. (Japanese Patent Publication No. 5-58755). This device basically consists of a water splitting section and a gas-liquid separation section. In the water splitting section, a device that jets high-pressure water from a nozzle toward an impingement wall to split it into fine water droplets,
A device that sprays water onto a rotating disk and applies centrifugal force to the sprayed water to break up fine water droplets, using an ultrasonic humidifier,
A device that vibrates water to break it into fine water, or a device that sprays water on a rotating impeller and hits the water with the impeller to break it into fine water droplets is used. The gas-liquid separation section
For example, a cyclone separator. According to the cyclone separator, the humid air containing negative ions can be extracted to the outside by centrifugally separating the fine water droplets from the air while swirling the fine water droplet mixed air.

One of the attempts to reduce the size of the negative ion generator and use it as a home air cleaner is disclosed in Japanese Utility Model Application Laid-Open No. 4-1 / 4-1.
There is an air purifier described in Japanese Patent No. 26717. According to this air purifier, as shown in FIG.

As described above, the negative ion generator is used also as a cleaner for indoor air, but the air to be delivered is humid air containing negative ions. With respect to the physiological effects of air ions, negative (negative) ions give a pleasant mood and positive (positive) ions give an unpleasant mood. In general, anions have a parasympathetic nerve stimulating action and restore abnormal biological functions to physiological states. Again, it is necessary to consider its proper amount, and even if it is a negative ion, its excess action is positive ionic. Positive ions are said to stimulate the sympathetic nerve (water and life,
Keiichi Morishita, Midori Shobo, p. 74, 1992).
In addition, if the air is humid and discharged in a large amount, the room becomes high in humidity, and a comfortable environment is impaired.

As described above, the supply amount of negative ions greatly affects the environment, and the state of life (at wake-up, at activity, at bedtime).
It is preferable that a comfortable environment can be set according to the conditions. In particular, air containing air ions and negative ions cannot be directly sensed like the air temperature for cooling and heating of an air conditioner. Therefore, it is preferable that an appropriate operation mode can be selected according to the use condition more than the air conditioner.

An object of the present invention is to provide a negative ion generator capable of easily selecting an appropriate operation mode according to a use condition.

[0007]

In order to achieve the above object, in the negative ion generating apparatus according to the present invention, energy is applied to water, and the water is split into fine water droplets to generate negative ions in the air. A negative ion generator for blowing humid air containing negative ions to the outside, having a priority operation mode, wherein the priority operation mode includes a predetermined humidity,
In this mode, operation is performed by selecting important conditions such as air volume and energy consumption.

The automatic operation mode is an operation mode in which the humidity of humid air blown to the outside is controlled so as to approach a predetermined set humidity.

Further, in the negative ion generator having a manual operation mode, the manual operation mode is an operation mode in which the other operation modes are canceled and the operation conditions are manually selected.

The first cyclone cylinder 4 is a part that forms a water splitting section A. The inside of the cylinder receives a supply of water in the water tank 2 and ejects the water into the first cyclone cylinder 4.
have. The water splitting section A is a section that applies energy to supplied water, splits the water into fine water droplets, and generates negative ions in nearby air.

In this embodiment, an inner cylinder 15 is provided concentrically within the first cyclone cylinder 4, and the inner cylinder 15 is provided with a rotating body 14 and a ring 16 serving as a collision wall.
A motor 17 for rotating and driving the rotating body 14 is mounted in the inner cylinder 15, and its rotating shaft 17 a is inserted into a shaft hole 18 of the rotating body 14.
And the rotating body 14 is installed in a horizontal position within the body of the first cyclone cylinder 4.

As shown in FIG. 4, the rotating body 14 is composed of a combination of a pair of rotating plates 14a and 14b, is supported by a washer 19 and a stopper 20, passes the rotating shaft 17a of the motor 17 through the shaft hole 18, and Are tightened. The pair of rotating plates 14a and 14b form an umbrella shape, are vertically combined, and are held at regular intervals by stays 22. The upper rotating plate 14a has a water receiving portion 23 at the center, and the plate surface of the lower rotating plate 14b is a guide for guiding the water received through the receiving portion 23 in the downward inclined direction, and is formed on the periphery. The opening is the water discharge section 24.

The water in the water tank 2 is supplied to the cartridge tank 26.
Supplied from The water filled in the water tank 2 is supplied to the pump 2
The water is pumped up at 7, supplied from above to the rotating body 14 through a water supply pipe 25 arranged in the inner cylinder 15, and received from the receiving portion 23 into the rotating body 14. The water received in the rotating belt 14 is given energy in the rotating direction of the rotating body 14 and is jetted in the centrifugal direction from the water discharge portion 24 on the periphery. The jetted water collides with the inner surface of the ring 16 and becomes fine. Split into water droplets. The surface against which the water spouted from the rotating body 14 collides is a collision wall that splits the water into fine water droplets.

When water discharged from the rotating body 14 collides with the collision wall, an impact sound is generated. The reason why the ring 16 is installed in the first cyclone cylinder 4 and the inner surface of the ring 16 is used as a collision wall is to reduce the level of noise due to the impact sound. Of course, the inner surface of the first cyclone cylinder 4 can be used as a collision wall.

Fine water droplets are separated from the air by centrifugal force and humid air containing negative ions is blown into the outside air from the exhaust port 11.

Since the cyclone cylinders 4 and 5 are open above the water surface in the water tank 2, excess water generated in the water splitting section A and water separated by centrifugal force in the gas-liquid separating section B are It is returned to the inside of the water tank 2 along the inner walls of the cyclone cylinders 4 and 5, and is used for circulation.

In the present invention, a humidity sensor 28 and a temperature sensor 29 are provided at the intake port 9. The humidity sensor 28 and the temperature sensor 29 detect the humidity and temperature of the indoor air sucked into the intake port 9 and output an operation control command of the negative ion generator. The operation time of the negative ion generator according to the present invention is controlled by a timer (not shown). As driving modes, priority driving and
It has three operation modes: automatic operation and manual operation.

When the operation is started in any of the operation modes, the pump 27, the motor 17, and the blower 13 are started simultaneously. The automatic operation is a mode in which the humidity of the indoor air sucked into the intake port 9 is detected, and the driving of the blower is controlled in a direction in which the detected humidity approaches the set humidity.

The priority operation is an operation mode in which the operation of the negative ion generator is controlled by selecting priority conditions such as humidity, air volume, or energy consumption (power consumption) preset according to the user's preference. FIG. 5 shows the mode of the humidity priority operation. When this mode is selected, in step 201, the temperature sensor 29 detects the temperature of the room air sucked into the intake port 9 and outputs the detected temperature, and in step 202, the humidity sensor 28 detects the humidity of the room air. Then, the detected humidity is output, and in step 203, the set humidity is calculated based on the detected temperature and the detected humidity.

The set humidity is a value obtained by adding an arbitrary ratio (for example, 5/100) to the detected humidity (%), and is a target value of the indoor humidity. In step 204, the difference Δ between the set humidity and the detected humidity is calculated, and when the difference Δ is larger than the reference value, the blower 13 is strongly operated in step 205,
When the difference Δ is smaller than the reference value, the blower 13 is weakly operated in step 206, and when the detected humidity is higher than the set humidity, the operation of the blower 13 is stopped in step 207.

According to this mode, by controlling the humidity of the room air, the relative humidity in the room can be kept constant and a refreshing atmosphere can be formed in the room.

The air volume priority operation mode for controlling the air volume is a mode for controlling the operation time using a timer. FIG.
In step 301, this operation mode is selected.
If you set the operation start time to the timer with, after a certain time,
In step 302, the blower 13 starts weak operation.
When the set time of the timer elapses in step 303, the operation of the blower 13 is stopped in step 304.

Further, in step 305, when the time set in the timer elapses, in step 306, the blower 13
Starts weak driving, and after a certain period of time, step 30
At 7, an operation stop command is output to the blower 13. According to this mode, the blower 13
Can be operated quietly to emit negative ions into the room.

The energy saving priority operation mode for controlling energy consumption is a mode in which the operation and stop of the blower 13 are repeated. In FIG. 7, in step 401, the operation of the negative ion generator is started or stopped at appropriate time intervals. At the start of operation, a timer is operated. At step 402, the blower 13 is operated for a predetermined period of time (for example, 30 minutes) with a weak operation. When the operation is stopped, the timer is operated at step 403 and the operation is continuously stopped. According to this mode, intermittent operation is automatically performed, and power consumption is reduced.

In the above description, an example in which the blower 13 is controlled to be strong or weak in each of the operation modes of the priority operation has been described. The drive motor 17 of the rotating body 14 is controlled in synchronization with the strong or weak operation of the blower 13. You may make it rotate at high speed or low speed. When the rotating body 14 is rotated at a low speed, the noise level is reduced.

The automatic operation mode is an operation mode in which the set humidity is determined using environmental conditions as information, and the amount of generated fine water droplets and the amount of air blow are automatically controlled in a direction approaching the set humidity.

FIG. 8 shows an example of the automatic operation mode. When the automatic operation mode is selected, in steps 501 and 502, data on the temperature and humidity in the room where the negative ion generator is installed and information on the current time (time zones such as morning, noon, evening, and night) are obtained. In step 503, the installation humidity suitable for the time zone and the indoor environment is calculated, and in step 504, the optimal control for realizing the installation humidity is performed. As the control condition, one of 16 combinations of the condition of the rotation speed (strong, medium, weak, stop) of the rotating body 14 and the condition of the rotation speed (strong, medium, weak, stop) of the blower 13 is selected. Then, the humidity of the humid air blown from the negative ion generator to the outside is automatically adjusted to the set humidity by controlling the combination of the amount of generated fine water droplets and the blower. The rotation speed of the rotating body and the rotation speed of the blower are not limited to being changed stepwise, but may be changed steplessly to select a combination thereof. The priority operation mode and the automatic operation mode are selected by switching.

The manual operation mode is an operation mode in which both the priority operation mode and the automatic operation mode are canceled, and the strong and weak operation of the blower 13 is switched by a push button operation.

FIG. 9 shows an example of the operation panel 30. The operation panel 30 includes a power-on switch (operation) S ₁ , an air flow intensity switch S ₂ for manual operation, a high / low switch S ₃ for setting humidity, an automatic operation switch S ₄ , and a switch S ₅ for focusing operation. Priority running switch S _5, a switched mode plus the temperature condition in the automatic operation "refreshing" mode for controlling the wind "Good night", the mode for controlling the power consumption display of "low-energy" It has be instructed to clearly window W _1. Further, the operation panel 30, in addition to the push button S ₆ of the drainage operation, the display of the amount of water in the water tank, water supply, water exchange, and a display P such as loading of the tank.
