[0002]

2. Description of the Related Art As an example of a tableware dryer equipped with an ozone generator for sterilizing and deodorizing bacteria and odors, there is an invention disclosed in Japanese Patent Laid-Open No. 2-1210. Show it.

In the figure, 51 is the main body of the tableware dryer, 5
2 is a cupboard arranged at a predetermined position inside the main body 51, 53
Is a cover that can be opened and closed so as to cover the upper portion of the main body 51. A motor 54 and a fan 55 attached to the motor 54 are provided in the lower portion of the main body 51, and the air sucked from an intake hole 57 provided in the bottom surface of the main body 51 passes through a dust removal filter 58. The heating heater 56 produces warm air, which is blown out from the discharge port 59 to the cupboard 52 by the fan 55. 60 is a tableware placed on the cupboard 52, 61 is an exhaust hole provided in the upper part of the cover 53, 62 is a water pan which is arranged at the lower part of the cupboard 52 and is freely removable, 63 is an upper part of the dust removal filter 58 Is an ozone generator.

As shown in FIG. 21, the ozone generator 63 comprises a high voltage electrode 64, a low voltage electrode 65, a gap 66 between the high voltage electrode 64 and the low voltage electrode 65, and a high voltage generator 67 for the ozone generator. . Reference numeral 68 denotes an ozone decomposing filter (manganese dioxide) removably disposed inside the main body 51 of the exhaust hole 61 of the cover 53,
It acts as a catalyst that decomposes and treats ozone.

In the tableware dryer thus constructed, as shown in FIG. 20, when the tableware 60 is set on the tableboard 52 inside the main body 51, the cover 53 is closed and the power switch is turned "ON". The motor 54 rotates and the heater 56
Heats up. Then, the air sucked from the intake hole 57 by the fan 55 passes through the dust removal filter 58 and is warmed by the heater 56 to become warm air.
The water that has flowed out of the main body 51 and adheres to the surface of the tableware 60 is evaporated. At this time, ozone flows out into the main body 51 together with the air warmed by the ozone generator 63 arranged in the path from the intake hole 57 to the discharge port 59, and the ozone deodorizes and sterilizes the odorous components inside the main body 51. Is done.

[0006]

The conventional tableware dryer as described above deodorizes and sterilizes the odorous components remaining even after washing and rinsing the tableware 60 and various bacteria growing inside the main body 51 with ozone. It is supposed to prevent the generation of offensive odor and the growth of various bacteria. However, if the amount of ozone is too large, it becomes a harmful substance and affects the human body. Therefore, in order to eliminate the danger, an ozone decomposing filter 68 is provided on the cover 63 as in a conventional tableware dryer, but the danger cannot be completely eliminated and the structure is extremely complicated. Also,
Since a high voltage is required to generate ozone,
The place of installation of the tableware dryer was limited and there was a problem with safety.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a highly safe tableware dryer and a control method therefor capable of surely deodorizing and sterilizing with a simple structure. It is what
