Ozone is effective as a disinfectant because it has a strong oxidizing effect and no residual property. However, in order to obtain a sufficient disinfecting and deodorizing effect, ozone is used. It is necessary to increase the concentration. When the concentration of ozone is increased, there is a problem that the fabric such as a futon discolors or deteriorates due to a strong oxidizing action. In addition, it is necessary to decompose high-concentration ozone after use by using an ozone decomposition catalyst to render it harmless.

However, by mixing (using) ozone and negative ions, it is possible to enhance the disinfection effect with a low concentration of ozone, and the higher the concentration of negative ions, the higher the disinfection effect. It has become clear in recent years. Then, the negative ion concentration is increased (for example, 2 ×
It has been clarified that a sufficient sterilization and deodorization effect can be obtained even when the ozone concentration is extremely low (for example, about 0.05 ppm) by the use of 10 ¹² particles / m ³ ). By making the ozone concentration extremely low in this way, it is possible to directly discharge used ozone to the atmosphere, and an ozone decomposition catalyst becomes unnecessary. By the way, the environmental standard of ozone concentration is
It is 0.1 ppm (upper limit).

Therefore, in the ozone cleaner of the present invention, the ultraviolet lamp 9 has the extremely low concentration (0.1 mm) as described above.
(Approximately 05 ppm) of ozone, and can be released directly to the atmosphere. The negative ion generator 15 is set so as to generate the above-mentioned negative ions (2 × 10 ¹² / m ³ ). This allows

The generated ozone is introduced into the duct 5 together with the air filling the case 2 and the outlet 5 c
It is released together with the negative ions generated in the vicinity. By directly releasing ozone and negative ions into the room in this manner, deodorization and the elimination of various bacteria floating in the air are effectively performed. Therefore, the ozone cleaner 1 can be used as an air purifier. Although the heater 11 is not used in the indoor mode described above, the heater 11 can be used as a heater using the heater.

When the futon is to be deodorized and sterilized, the user lowers the louver 2c of the ozone cleaner 1 and attaches the air sheet nozzle 31 to the outlet 5c as shown in FIGS. Then, a hose 30c of the air sheet 30 is attached, and the air sheet 30 is wrapped around the air sheet nozzle 31 by a belt 30e and fixed tightly. Next, the quilt is placed on the mattress 35, the quilt is laid on the quilt 36, and the air sheet 30 is interposed between them.

Next, the user operates the control panel 4
Press the futon switch S2, cotton 90 minutes, feathers and wool 60
Start switch SW
push. The control circuit 21 turns on the ultraviolet lamp 9, drives the fan motor 7, heats the heater 11 to a predetermined temperature, and causes the negative ion generator 15 to generate negative ions. As a result, heated and dried air (warm air) containing ozone and negative ions is discharged from the outlet 5c of the ozone cleaner 1 and introduced into the air sheet 30, whereby the air sheet 30 expands.

The air introduced into the air sheet 30 is blown out from the opening 30d as shown by the arrow in FIG. 9 to fill the space between the mattress 35 and the comforter 36, thereby performing deodorization and sterilization. At this time, the air is also blown out from the bag-shaped side portions 30a and 30b forming the frame of the air sheet 30 to perform deodorization and sterilization. The air becomes warm air by being heated, and the futon is dried at the same time.

In the case of exterminating ticks, selecting the switch for exterminating ticks sets the treatment time to the time for extermination of the ticks (for example, 30 minutes), and negative ions are added to the heated ozone-containing air. By being added, it is possible to exterminate mites effectively. When simply warming the futon before going to bed, selecting a warming switch sets the warming time (for example, 15 minutes) to warm the futons 35 and 36.

The heating temperature of the heater may be adjustable, and the temperature for extermination of the mites and the temperature for warming the futon may be changed. Further, in heating the futon, generation of ozone and negative ions may be stopped to discharge only warm air. Further, as shown in FIG. 6, shoes,
Put the object 37 such as slippers and clothes to be deodorized and sanitized, attach it to the outlet 5c, and select a switch such as cotton, feathers and wool, or mite elimination as the futon mode, thereby deodorizing and sterilizing these. Alternatively, processing such as extermination of ticks can be performed. In the futon mode, the heater 11 is used as described above.

The above are only some examples of the use of the ozone cleaner of the present invention, and various combinations are possible depending on the application. The amount of ozone generation and the amount of negative ion generation can be controlled by changing the applied voltage within a range that satisfies the environmental standards. Therefore, by making it possible to set the ozone generation amount and the negative ion generation amount according to the purpose of use, more effective deodorization and sterilization can be performed.
