[1-1-2. Configuration of electrostatic atomization generation unit]
In FIG. 2, the electrostatic atomization generation unit 81 includes an electrostatic atomization generation device 98 and a resin case 104. The electrostatic atomization generator 98 is fixed to a resin case 104, and includes a discharge electrode 99, a counter electrode 100 disposed opposite to the discharge electrode 99, a water supply means 101 for supplying water to the discharge electrode 99, and a discharge electrode 99. It has voltage application means (not shown) for applying a high voltage between the electrode 99 and the counter electrode 100.

The electrostatic atomization generator 98 electrostatically atomizes the water supplied to the discharge electrode 99 by applying a high voltage between the discharge electrode 99 and the counter electrode 100 using a voltage application means, and generates charged fine particle water. to occur. Here, a negative voltage of 5.5 kV is applied to cause electrostatic atomization, and feedback control is performed so that the discharge current value at that time becomes 6 μA.

In electrostatic atomization, when a high voltage is applied, the discharge electrode 99 side becomes a negative electrode and charges are concentrated, and the water adhering to the surface of the discharge electrode 99 rises in a conical shape to form a Taylor cone. This is done by repeating Rayleigh fission, in which charges are concentrated at the tip of the tip and become highly dense, and the water splits and scatters as it bursts due to the repulsive force of this high-density charge. At this time, the formation of a Taylor cone is affected by the wettability of the surface of the discharge electrode 99. If the wettability is low, a predetermined Taylor cone will not be formed and the amount of electrostatic atomization cannot be secured, so the discharge electrode It is necessary to ensure a predetermined amount of wettability on the surface of 99. Here, the amount of water required for electrostatic atomization is about 0.5 ml/h.

[1-2. motion]
The operation of the clothing processing apparatus 10 configured as described above will be described below.

[1-2-1. Operation of clothing processing device 10]
The operation of the clothing processing device 10 will be explained based on FIG. 1.

When the heat exchange type fan 92 rotates during drying operation of the clothes processing apparatus 10, air inside the rotary drum 74 is sucked toward the heat exchange type fan 92 from behind the rotary drum 74. Air sucked in by the heat exchange fan 92 is heated by a heat source 97 and returned to the inside of the rotating drum 74 through a wind tunnel 96. This warm air comes into contact with the damp clothes inside the rotating drum 74 after being washed and dehydrated, thereby warming the clothes. At the same time, as the rotating drum 74 rotates, the clothes are agitated inside the rotating drum 74, and moisture evaporates from the clothes. Then, this moisture-containing air is sucked in by the heat exchange type fan 92, heated by the heat source 97, and returned to the inside of the rotating drum 74.

As the moist air circulates in this manner, the temperature of the air inside the rotating drum 74 eventually reaches approximately 55 degrees and the humidity reaches approximately 100%. This state is hereinafter referred to as a constant rate drying state in drying operation.

[1-2-2. Operation of electrostatic atomization generation unit 81]
During the drying operation, the heat exchange type fan 92 rotates and the air inside the rotating drum 74 is sucked toward the heat exchange type fan 92. As a result, the amount of air flowing out from the inside of the electrostatic atomization generating unit 81 to the rotating drum 74 increases as shown by arrows A2 and B2.

Accordingly, air outside the rotating drum 74 flows into the electrostatic atomization generating unit 81 from the second air port 107a and the second air port 107b, as shown by arrow C1 and arrow D1. The air flowing in from the outside of the rotating drum 74 is mixed with the air shown by arrows A1 and B1 entering from the inside of the rotating drum 74 in the electrostatic atomization generating unit 81. Then, the air accompanied by the charged particulate water generated by the electrostatic atomization generator 98 flows into the inside of the rotating drum 74 from the first air port 105a and the first air port 105b, as shown by arrow A2 and arrow B2. leak. The sizes of the second air port 107a and the second air port 107b are determined so that the temperature and humidity of the air inside the electrostatic atomization generation unit 81 are appropriate. It is smaller than the air port 105b.

Appropriate temperature and humidity exist in the electrostatic atomization generator 98 to stably generate charged fine particle water. For example, when the temperature is 5°C, the humidity is about 80% or more, when the temperature is 10°C, the humidity is about 60% or more, and when the temperature is 15°C, the humidity is about 45% or more. Further, when the temperature is about 20° C. or more and about 50° C. or less and the humidity is about 30% or more and about 85% or less, charged fine particle water can be generated more stably. Note that when the temperature is about 60° C. or higher or the humidity is about 85%, charged fine particle water may not be generated.

In the constant rate drying state during drying operation, high temperature and high humidity air inside the rotating drum 74 is taken into the electrostatic atomization generation unit 81 through the first air port 105a and the first air port 105b, and Low-temperature and low-humidity air outside the rotating drum 74 is taken in through the second air port 107a and the second air port 107b.

If the air inside the electrostatic atomization generation unit 81 is high in temperature and humidity, the electrostatic atomization generation device 98 cannot stably generate charged particulate water. Therefore, low-temperature and low-humidity air from the outside of the rotating drum 74 is taken in from the second air port 107a and the second air port 107b, and the temperature and humidity of the air mixed inside the electrostatic atomization generation unit 81 are adjusted to the charged particulate water. so that the conditions are suitable for it to occur. As a result, the electrostatic atomization generating device 98 can stably generate charged fine particle water, and discharge the charged fine particle water from the first air port 105a and the first air port 105b into the rotating drum 74 to rotate. Clothes in the drum 74 can be sterilized and deodorized.

[1-3. Effects, etc.]
As described above, in the first embodiment, the clothing processing apparatus 10 includes the outer frame 72, the rotating drum 74, the opening 79, the lid 80, the electrostatic atomization generator 98, and the electrostatic atomization generation unit. 81. The rotating drum 74 is rotatably contained within the outer frame 72. The opening 79 is formed on the front surface of the outer frame 72, and the lid 80 covers the opening 79 so as to be openable and closable. The electrostatic atomization generation unit 81 includes an electrostatic atomization generation device 98 that generates charged fine particle water, and is connected to the rotating drum 74.
It emits charged microparticle water towards the inside of the system. The electrostatic atomization generation unit 81 has a first air port 105a, a first air port 105b, a second air port 107a, and a second air port 107b. The first air port 105a and the first air port 105b take in the air inside the rotating drum 74, and the second air port 107a and the second air port 107b take in the air outside the rotating drum 74.

Thereby, the high temperature and high humidity air inside the rotating drum 74 can be mixed with the low temperature and low humidity air outside the rotating drum 74 inside the electrostatic atomization generating unit 81 . Therefore, charged particulate water can be stably generated during drying operation, and by bringing the charged particulate water into contact with clothing, the clothes can be sterilized and deodorized in a short time.

The electrostatic atomization generating device 98 is fixed to the resin case 115, and the electrostatic atomization generation unit 181 is arranged on the drum support plate 90.

In the electrostatic atomization generation unit 181, a first air port 111, a second air port 112, and a third air port 113 are provided in the resin case 115. The second air port 112 is provided on the side where the counter electrode 100 is provided, and the second air port 112 is provided on the side where the water supply means 101 is provided. The first air port 111 and the third air port 113 are air ports through which air inside the rotating drum 74 enters and exits the electrostatic atomization generation unit 181, and the second air port 112 is an air port through which air inside the rotating drum 74 enters and exits the electrostatic atomization generating unit 181. This is an air port through which air enters the electrostatic atomization generation unit 181.

The blowing means 110 is arranged between the first air port 111 and the second air port 112 and the electrostatic atomization generator 98. The blowing means 110 sucks air through a first air port 111 and a second air port 112, passes through the electrostatic atomization generator 98, and generates air that is returned to the rotating drum 74 through a third air port 113.

In the constant rate drying state during the drying operation, the air inside the rotating drum 74 is high temperature and high humidity air that has been heated by the heat source 97 and has removed moisture from the clothes. This air has a temperature of about 55 degrees and a humidity of about 100%.

As shown in FIG. 3, when the blowing means 110 is operated, the air inside the rotating drum 74 flows from the first air port 111 as shown by the arrow E1, and the air inside the rotating drum 74 flows from the second air port 112 as shown by the arrow F1. External air flows into the electrostatic atomization generation unit 181. These airs are mixed by the blowing means 110 and sent to the vicinity of the electrostatic atomization generator 98. The sizes of the first air port 111 and the second air port 112 are such that the high temperature and high humidity air inside the rotating drum 74 and the low temperature and low humidity air outside the rotating drum 74 are appropriately mixed. It's getting dark.

The temperature detection means 114 detects the temperature of the air inside the electrostatic atomization generation unit 181. When the temperature detected by the temperature detection means 114 is within a predetermined temperature range, the control device 70 operates the electrostatic atomization generator 98. The predetermined temperature at which the electrostatic atomization generator 98 is operated is set to 20° C. or higher and 50° C. or lower.

The charged particulate water generated by the electrostatic atomization generator 98 passes through the third air port 113 as indicated by the arrow G1, is discharged into the rotating drum 74, and is diffused toward the clothing inside the rotating drum 74. Ru. The charged particulate water discharged into the rotary drum 74 is transferred to the clothing along with the air sucked from the rear of the rotary drum 74 toward the heat exchange fan 92 as the heat exchange fan 92 rotates during the drying operation. can be diffused into

The electrostatic atomization generating unit 181 has a first air port 111 that takes in air inside the rotating drum 74 and a second air port 112 that takes in air outside the rotating drum 74.

Thereby, the charged particulate water generated by the electrostatic atomization generator 98 can be sent into the rotating drum 74 on the wind generated by the air blower 110. Therefore, the charged fine particle water efficiently reaches the clothes inside the rotating drum 74, and the effect of sterilizing and deodorizing the entire clothes can be obtained in a shorter time.

As in the second embodiment, the blowing means 110 may be arranged between the first air port 111 and the second air port 112 and the electrostatic atomization generator 98.

This can prevent the charged particulate water generated by the electrostatic atomization generating device 98 from colliding with the blades of the blowing means 110 and being attenuated.

Further, as in the second embodiment, a temperature detection means 114 for detecting the temperature of the air in the electrostatic atomization generation unit 181 may be provided.

Therefore, unnecessary operation of the electrostatic atomization generator 98 can be reduced.

In the second embodiment, the temperature of the air is detected by the temperature detection means 114, but the electrostatic atomization generation unit A similar effect can be obtained by estimating the temperature of the air at 181. Further, even if this is applied to the first embodiment, the same effect can be obtained.
