  INDUSTRIAL APPLICABILITY The present invention can prevent unpleasant odors from occurring by suppressing the propagation of germs even when the laundry is dried indoors.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The present invention uses an electrostatic atomizer that generates nanometer-sized charged fine particle water, and performs a sterilization / deodorization (deodorization) treatment when drying laundry that has been dried indoors with the charged fine particle water and its First, an electrostatic atomizer will be described.

  As shown in FIG. 4, the electrostatic atomizer 1 includes a water particle discharge unit 11 and a counter electrode 12 that function as a pair of electrodes, and water supply means (a liquid reservoir) for supplying water to the water particle discharge unit 11. Unit 14 and transport unit 15), and a voltage application unit 13 that applies a high voltage between the water particle emitting unit 11 and the counter electrode 12, and between the water particle emitting unit 11 and the counter electrode 12. A mist M of nanometer-sized charged fine particle water is generated from the water in the water particle discharge section 11 by applying a high voltage to the water.

  In the example of the electrostatic atomizer 1 shown in FIG. 4, a liquid reservoir 14 serving as a water supply means and a rod-shaped transport unit 15 made of a porous material whose lower end is immersed in water placed in the liquid reservoir 14. A liquid application electrode 16 for holding the transport unit 15 and applying a voltage to water, a counter electrode 12 facing the water particle discharge unit 11 at the tip of the transport unit 15, and the liquid application electrode 16 The voltage application part 13 which applies a high voltage between the opposing electrodes 12 is comprised.

  Both the counter electrode 12 and the liquid application electrode 16 are made of a synthetic resin mixed with a conductive material such as carbon or a metal such as SUS.

  The conveying unit 15 is formed of a porous material in a rod shape. In this embodiment, the conveying unit 15 is made of ceramic particles having a particle size of 2 to 500 μm, and the pores in the gap are arranged in an open cell shape with 1 to 250 μm. It is formed. The upper end of the transport unit 15 is a needle-shaped water particle discharge unit 11. The upper part of the transport unit 15 protrudes upward from the liquid application electrode 16, and the lower part projects downward from the liquid application electrode 16. It comes into contact with water stored in the reservoir 14.

  The counter electrode 12 is grounded, the voltage application unit 13 is connected to the liquid application electrode 16 to apply a high voltage, and the transport unit 15 formed of a porous material is put into the liquid storage unit 14 by capillary action. When the water is sucked up, the water particle discharge part 11 at the upper end of the transport part 15 functions as a substantial electrode on the liquid application electrode 16 side. The voltage application unit 13 is preferably one that can provide an electrolytic strength of 500 V / mm or more, particularly 700 to 1200 V / mm.

  And by applying a high voltage between the conveyance part 15 and the counter electrode 12 by the voltage application part 13, the water of the water particle discharge | release part 11 receives big energy with a high voltage, and repeats a division | segmentation exceeding surface tension. Electrostatic atomization that causes so-called Rayleigh splitting and generates mist M (for example, 10 to 30 nanometers) of ions having a particle size of nanometer size is performed. , Substances that become the source of deodorization and sterilization such as superoxide) are contained in the split water and jump out into the air. In this way, a mist M of nanometer-sized charged fine particle water containing active species is generated from the water particle emitting portion 11. Active species are very reactive, and thus have a high effect on the decomposition of malodorous components and the suppression of mold generation. However, when they are present alone, their lifetime is short. However, in the nanometer-size charged fine particle water obtained by the electrostatic atomizer 1, the active species are present as if they are encapsulated in water molecules, and thus the life is prolonged, and as described above. The nanometer size is extremely small, so it floats in the air for a long time and has high diffusivity. Active species (hydroxy radicals, superoxide, etc.) deodorize the air in a wide range of space, disinfect and propagate molds and fungi. In addition, since the charged fine particle water is very small with nanometer size, it becomes possible to enter the gaps between the fibers of the laundry which has been dried in the room, and thereby the germs attached to the laundry. Can be sterilized, or malodorous components can be decomposed. The following shows the deodorization reaction formula of the odor and the active species contained in the nanometer-size charged fine particle water.

Ammonia 2NH ₃ + 6 · OH → N ₂ + 6H ₂ O
Acetaldehyde CH ₃ CHO + 6 · OH + O ₂ → 2CO ₂ + 5H ₂ O
Acetic acid CH ₃ COOH + 4 · OH + O ₂ → 2CO ₂ + 4H ₂ O
Methane gas CH ₄ + 4 · OH + O ₂ → CO ₂ + 4H ₂ O
Carbon monoxide _{CO + 2 · OH → CO 2} + H 2 O
Nitric oxide 2NO + 4.OH → N ₂ + 2O ₂ + 2H ₂ O
Formaldehyde HCHO + 4 · OH → CO ₂ + 3H ₂ O
In the above deodorization reaction formula, .OH represents a hydroxy radical.

  When the electrostatic atomizer 1 is in operation, the water stored in the liquid reservoir 14 is consumed little by little. Therefore, a water level sensor (not shown) is provided in the liquid reservoir 14 and the water level sensor keeps constant. When the water level is detected, the electrostatic atomizer 1 may be automatically supplied with water from a water supply pipe (not shown) into the liquid reservoir 14. Water supply work is no longer necessary.

A plurality of thermoelectric elements 23 arranged opposite to each other are sandwiched between both Peltier circuit boards 22a and 22b, and adjacent thermoelectric elements 23 are electrically connected to each other by circuits on both sides. The Peltier unit power supply 25 is provided so that heat is transferred from one Peltier circuit board 22a side to the other Peltier circuit board 22b side by energizing the thermoelectric element 23. The circuit board 22a is connected to the cooling part R side, and the other Peltier circuit board 22b is connected to the heat dissipation part H side.

To connect.

  The cooling part R is formed in a substantially dish-like shape that opens upward so that the liquid reservoir part 14 that can store the dew condensation water W is formed therein, and the liquid application electrode 16 is formed on the inner upper surface of the cooling part R. Is provided.

  The liquid application electrode 16 has an upper end portion that serves as the water particle discharge portion 11 and is formed of a porous material or has a fine hole or a fine groove (a fine hole 15a in the example of FIG. 5). The dew condensation water W stored in the cooling part R of the part becomes a transport part 15 capable of transporting to the water particle discharge part 11 at the upper end part serving as a discharge part by capillary action. In addition, by forming the water particle discharge part 11 with metal or forming a metal surface film to form a surface with high thermal conductivity and being attached to be thermally connected to the cooling part R, The dew condensation water W may be condensed directly on the surface of the water particle discharge part 11. Alternatively, the liquid application electrode 16 may be provided on the transport unit 15 made of porous ceramic or the like whose upper end is the water particle discharge unit 11.

  The cooling part R is provided with an overflow hole 26, and when the condensed water stored in the liquid storage part 14 reaches a certain level or higher, excess water is stored through the overflow hole 26 in the lower excess water storage tank. 27 can be discharged.

An intake port 70a is formed at the upstream end of the air flow path of the casing, and a discharge port 70b is formed at the downstream end. Of the two filters, the filter 71 on the upstream side has a fine mesh shape, thereby removing dust and fine particles in the air. The downstream filter 72 is made of activated carbon or an oxidation catalyst and decomposes and removes unpleasant odor components in the air. By providing the dew condensation means and the electrostatic atomizer 1 on the downstream side of the filters 71 and 72, clean air is supplied to the dew condensation means, and the dew condensation water W contains depleted odor components.
