Part of the water is scattered toward the filter from a large number of holes of the water absorption pipe, and dry air is passed through the filter wet with the water to obtain a humidifying effect.

Also, in the case of the cold air fan, the actual opening is 63-1343.
As described in Japanese Patent No. 26, the water stored in the water storage tank is absorbed by a humidifying filter, and air is blown through the humidifying filter, whereby the water in the humidifying filter is vaporized and the heat of vaporization at that time causes the vaporization. Lower the temperature of the blast air,
I try to blow it as cold air.

As described above, in the structure in which water is stored in the water storage tank, bacteria, fungi, algae, etc. may be generated due to water spoilage, and an offensive odor may be generated due to the generation.

However, when the dehumidifying agent is contained in the humidifying filter, the deodorizing performance is inferior in sustainability due to aging, and the humidifying filter needs to be replaced in order to maintain the deodorizing performance. There is a maintenance problem such as coming.

Further, when a chemical having a deodorizing and sterilizing effect is put in the water storage tank, it is necessary to purchase a special chemical, which causes a problem that it is difficult to handle.

Further, since the humidifier is a circulation system which basically takes in indoor air, passes it through the humidifying filter, and then blows it out into the room, bacteria floating in the air adhere to the humidifying filter, There is a problem that bacteria adhere to the filter to cause bacteria to grow in the humidifying filter, which causes odor generation.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a humidifying device capable of removing airborne bacteria in the air in a room, preventing bacterial growth in a humidifying filter, and reducing odor generation. To aim.

It is attached to the humidifier to generate positive ions and negative ions from the ion generator during humidification operation, and removes suspended bacteria contained in the indoor air taken in before entering the humidification filter. It is intended to reduce the generation of odor by preventing the reproduction of

That is, the present invention comprises a water storage tank for storing water, a humidification filter for humidifying the water in the water storage tank, a blowing means for blowing air through the humidification filter, and an ion generator for generating ions. The present invention provides a humidifying device configured to blow air containing ions generated from the ion generating device to a humidifying filter during a humidifying operation.

An ion generator 18, a blower 19, a water pump 16, a heating body 20, and a switching damper 23 driven by the drive circuits 58 to 62 are provided. Then, the control unit 57 processes the signal from the input side and outputs the signal to each of the drive circuits 58 to 62 to control the ion generator 18, the blower 19, the heating body 20, and the switching damper 23. ing.

The operation switch group 50 includes the operation switch 5
1, a humidification switch 52, an ion operation switch 53, and a humidity setting switch 54.

Next, the operation of the above humidifier will be described.
First, the lid 11 (see FIG. 1) of the apparatus body 10 is opened, and the water supply tank 12 is set in the water receiving tank 13. When the operation switch 51 of the operation unit (not shown) is turned on and the humidification switch 52 is pressed to select the automatic operation mode, the automatic humidification operation starts. Humidification switch 52
When you press sequentially, "Auto" → "Strong" → "Medium" →
The humidification operation mode of "weak" → "automatic" is selected, and the humidification operation mode is selected. Humidification switch 52
Is turned on, the humidification operation is performed, and the ion generator 18 is automatically operated together.

In the automatic humidification operation, the water feed pump 16 is operated in accordance with the difference between the humidity detected by the humidity sensor 63 and the humidity set by the humidity setting switch 54, or in accordance with the difference between the humidity stored in advance and set. The amount of water supplied is controlled, or the rotation of the blower 19 is controlled to change the amount of humidification and the humidification is automatically controlled.

In the strong humidification operation mode, the medium humidification operation mode, and the weak humidification operation mode, preset humidity values (for example, "strong" is 60%, "medium" is 50%, and "weak").
40%) and the humidity detected by the humidity sensor 63 according to the difference between the amount of water supplied by the water pump 16 and the driving of the heating body 20, the rotation of the blower 19, and the like. Humidity is automatically controlled by changing the amount.

In any of the above automatic humidifying operation, strong humidifying operation, medium humidifying operation, and weak humidifying operation, the ion generator 18 is operated in combination. During this humidifying operation, the switching damper 23 serves as a path to the outlet 24,
The blower 19 is driven to take in air, pass through the ion generator 18, pass through the humidification filter 14 and air containing positive ions and negative ions, and discharge the air into the room through the air outlet 24.

As described above, when the ion generator 18 is also operated while performing the humidifying operation, the humidity in the air increases,
By reducing the habitation rate of the virus bacterium of the cold and further generating positive ions and negative ions alternately by the ion generator 18, airborne bacteria can be removed, and comfortable air can be obtained.

Further, since the air containing positive and negative ions sterilizes airborne bacteria in the middle of the path, the humidification filter 14 can prevent the growth of bacteria, resulting in the removal of bacteria, resulting in odor. The sources of occurrence of are reduced.

Further, during the humidifying operation, the air taken in by driving the blower 19 is heated by the heating body 20 and passed through the ion generator 18, and the air containing positive and negative ions is humidified by the humidifying filter 14. Can be sent to.
In this case, when the temperature of the air containing positive and negative ions is raised to 30 to 35 ° C. (about 10 to 15 ° C. higher than usual) and sent to the humidification filter 14, the humidification filter 14 is killed while killing the bacteria. Since 14 is dried, generation of odor by the humidification filter 14 is significantly reduced.

Further, during this humidifying operation, the sucked air is heated by the heating body 20 and the air whose temperature has risen is passed through the humidifying filter 14, whereby a large amount of water is removed from the humidifying filter 14. It is possible to release air containing a lot of water.

As described above, normally, the heating body 20 is not driven during the humidifying operation, but when operating with a large amount of humidification or when it is desired to reach the set humidity in a short time,
Since the heating element 20 is driven, it is easy to use and the usability is improved.

When the difference between the set humidity and the detected humidity is large, the amount of water supplied by the water pump 16 is increased, and the rotation speed of the blower 19 is further increased to send a large amount of air to the humidification filter 14. The humidifying operation is controlled to increase the amount of water removed from the humidifying filter 14.

When the ion generator 18 is operated independently, the ion operation switch 53 is pushed in sequence,
The ion generator 18 is operated in the order of “cluster” → “cleaning 1” → “cleaning 2” → “off” → “cluster”.

In the cluster operation, the ion generator 18 is operated independently, the switching damper 23 is used as a path to the ion outlet 22, the blower 19 is driven to take in air, and the ion generator 18 is allowed to pass therethrough to generate positive ions. Air containing negative ions is discharged from the ion outlet 22.
At this time, the water supply pump 16 involved in humidification is in a stopped state.

The cleaning 1 operation is performed by the ion generator 1
This is a mode in which the periphery of the humidification filter 14 is cleaned while the water supply pump 16 is stopped in the single operation of No. 8. The switching damper 23 serves as a path to the humidification filter 14, drives the blower 19 to take in air, and supplies the ion generator 18
Through the humidification filter 14 and the air containing positive and negative ions is discharged from the outlet 24. Thereby, the bacteria floating around the humidification filter 14 are removed.

The cleaning 2 operation is performed by the ion generator 1
8 is a mode in which the heater 8 is driven and the water supply pump 16 is stopped, and the periphery of the humidification filter 14 is cleaned. The switching damper 23 serves as a path to the humidification filter 14, and drives the blower 19 to heat the taken-in air, while passing the ion generator 18 and blowing the air containing positive ions and negative ions through the humidification filter 14. It is discharged from the outlet 24. As a result, while the humidifying filter 14 is being dried, bacteria floating around the humidifying filter 14 are removed and discharged from the air outlet, so that it is possible to reduce the generation of odors such as scale on the humidifying filter 14.

When the ion generator 18 is not required during the humidifying operation, the driving can be stopped by selecting "OFF" of the ion operating switch, and the ion generating apparatus 18 can be used only in the humidifying operation. Wide usage.
In this case, the switching damper 23 is switched to a path that passes through the humidification filter 14 and reaches the air outlet 24.

Regarding the generation of odors from the humidifying filter, the present inventors will give an example in which air containing positive ions and negative ions is blown to the humidifying filter during humidifying operation, as in the present embodiment. As a result of conducting sensory evaluations on the comparative example and the comparative example when it was not so, when comparing the two, the generation of odor was recognized in the case of the comparative example, whereas the generation of almost odor was recognized in the case of the example. I couldn't do it.

The present invention is not limited to the above embodiment, and it goes without saying that modifications and changes can be made within the scope of the present invention. For example, in the above-described embodiment, the ion generator is an apparatus that alternately generates positive ions and negative ions, but either positive ions or negative ions, or airborne bacteria are actively removed. It may be a device that generates only positive ions having a function.

Further, during the humidifying operation, the switching damper 23 is used as a path to the outlet 24, the blower 19 is driven to take in air, and the ion generator 18 is made to pass therethrough, and air containing positive ions and negative ions is introduced. It passes through the humidification filter 14 and is discharged into the room from the air outlet 24, and at the same time, the switching damper 23 is moved to the ion air outlet 22.
Alternatively, the switching damper 23 may be controlled so that air containing positive ions and negative ions is directly discharged from the ion outlet 22 into the indoor space.

Alternatively, the ion generator 18 is controlled to generate negative ions at regular intervals, and the switching damper 23 is used as a path to the ion outlet 22 in accordance with the control, and negative ions are included. Alternatively, the air may be directly discharged into the indoor space from the ion outlet 22.

As described above, by controlling the ion generator 18 and the switching damper 23 by the control unit 57, positive ions and negative ions or negative ions are directly introduced into the indoor space from the ion outlet 22 even during the humidifying operation. Can be released. The positive ions generated by the ion generator 18 are cluster ions in which a plurality of water molecules are attached around the hydrogen ion (H ⁺ ) and are H ⁺ (H ₂ O) _m
(M is a natural number). Negative ions are cluster ions in which a plurality of water molecules are attached around oxygen ions (O ₂ ⁻ ), and are represented as O ₂ ⁻ (H ₂ O) _n (n is a natural number).

These positive and negative ions are aggregated in suspended matter (particles, bacteria) in the discharge space and chemically react with each other, and hydrogen peroxide H ₂ O ₂ or hydroxyl radical / OH as an active substance. And inactivates suspended particles by the oxidation reaction, and also acts to kill suspended bacteria,
Air purification performs the removal of odor substances and airborne fungi indoor space wide range Ru performed.

Since it is removed before entering, it is possible to prevent bacterial growth in the humidification filter and reduce odor generation.
