DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 6 denotes a dryer main body, which is a drying chamber 8 for storing and drying the stored items 7 such as cutting boards and dishes, a heater 9 for supplying warm air into the drying chamber 8 and a main unit. A warm air device 11 including a fan motor 10, an exhaust path 12 for exhausting the hot air circulated in the drying chamber 8, and an exhaust path for adsorbing odors generated from the stored items 7 in the drying chamber 8 are arranged. A deodorizing device 13 composed of a honeycomb catalyst that adsorbs and oxidizes and decomposes sulfur compounds and nitrogen compounds that have been installed at room temperature, and a sub fan motor that sends the odor continuously generated from the stored items 7 to the deodorizing device 13 after completion of drying 14, the heater 9, the main fan motor 10 and the auxiliary fan motor 14 are turned on / of
It is the structure provided with the control apparatus 15 which performs F control. The control device 15 receives the control signal from the microcomputer 16 and the microcomputer 16 and turns the heater 9 ON / OFF.
The main fan motor 1 receives a control signal from the heater drive circuit 17a which is turned off and the microcomputer 16
Main fan motor drive circuit 17 for driving 0 ON / OFF
b, a sub fan motor drive circuit 17c which receives a control signal from the microcomputer 16 to drive the sub fan motor 14 ON / OFF. Further, the solid arrow in the figure indicates the air flow when the main fan motor 10 is driven, and the dotted arrow indicates the air flow when the sub fan motor 14 is driven.

In the above structure, the controller 15 operates so that the output ports D0 and D1 of the microcomputer 16 in the controller 15 output H (load ON) at the start of drying.
Signal) to the output L (load OFF signal), and the ON signal of the output port D0 is transmitted to the heater driving circuit 17a in the control device 15, so that the heater driving circuit 17a operates as a heater.
Turn on the TA-9. At the same time, the ON signal of the output port D1 is transmitted to the main fan motor drive circuit 17b in the controller 15, and the main fan motor drive circuit 17b turns on the main fan motor 10 to supply warm air into the drying chamber 8. Then, the contents 7 are dried. The warm air circulated in the drying chamber 8 is discharged to the outside of the machine through the deodorizing device 13 in the exhaust path 12, and the odor generated from the stored items 7 at this time is adsorbed by the deodorizing device 13 [period (A)]. ]. Next, after drying for a certain period of time, the output port D0 of the microcomputer 16 returns to the output H and the driving of the heater 9 is stopped to finish the drying, but the output of the microcomputer 16 is output. The port D1 continues to output L for a certain period of time, and the temperature in the drying chamber 8 decreases to near room temperature during this period, and at the same time, the odor generated from the stored items 7 is absorbed by the deodorizing device 13 during this period as well. [Period (B)]. After the period (B) has elapsed, the output port D1 of the microcomputer 16 returns to the output H, and at the same time, the output port D2 of the microcomputer 16 changes to the output L and the output port D2 of the output port D2 changes. The ON signal is transmitted to the auxiliary fan motor drive circuit 17c in the control device 15, the auxiliary fan motor drive circuit 17c turns on the auxiliary fan motor 14, and the air outside the machine is supplied into the drying chamber 8 to supply the main fan motor. The air that circulates in the drying chamber 8 is discharged to the outside of the machine through the deodorizing device 13 in the exhaust path 12, as when 10 is driven.
At this time, the odor generated from the stored items 7 is absorbed by the deodorizing device 13. After that, the output port D2 of the microcomputer 16 repeats the output L (period C1) and the output H (period C2) at a constant cycle, so that the auxiliary fan motor 14 continuously repeats ON / OFF drive to dry. The odor level that continues to be generated after the end is maintained at a low level that cannot be perceived by a person [period (C)]. Therefore, by continuously removing the odor generated from the stored items even after drying, the discomfort during use is reduced at any time. Further, even if the auxiliary fan motor 14 is continuously driven, the reduction of the odor level has a further effect, but there is no difference in the olfactory level of the person as compared with the present embodiment, and conversely, the contents of the storage item 7 are reduced. Since the odor continues to be generated for a long time even after drying, continuous driving during that time accelerates the deterioration of the life of the fan motor. Therefore, by controlling the ON / OFF of the auxiliary fan motor 14 at a constant cycle, it is possible to cope with deodorization for a long time while maintaining the level below a level that cannot be sensed by humans, and to reduce the deterioration of the life of the fan motor efficiently. The effect can be obtained.

Next, another embodiment of the present invention will be described. FIG. 3 shows another embodiment. In this embodiment,
O in the ON / OFF 1 cycle (T) of the auxiliary fan motor 14
The ratio of the N / OFF period (C3: C4) is set to be high immediately after the end of drying and then changed to a short period of the ON period as time passes (C3a> C3b).
>C3c>...> C3 (x)> C3 (x + 1)> ..., C4
a <C4b <C4c <... <C4 (x) <C4 (x + 1)
<...) As a result, the odor level after completion of drying can be lowered to a low level that cannot be perceived by a person earlier, and the discomfort to the odor can be reduced at an early stage. According to the actual mechanism of odor generation, the amount decreases naturally according to
Even if it sees from the life of the fan motor, there is an effect that an efficient deodorizing operation can be performed.

In the above embodiment, the auxiliary fan motor 1
The ON / OFF 1 cycle (T) of 4 was made equal, but it is not limited to this, and as shown in FIG. 4, the ON / OFF 1 cycle (T) of the auxiliary fan motor 14 was changed over time. (T1 <T2 <T3 <T4 <... And, the ratio of the ON / OFF period of the auxiliary fan motor 14 is high immediately after the end of the drying, and then becomes higher as time passes.
The effect of the present invention can be achieved even if the ratio of the N period is changed to be shorter. In addition, the auxiliary fan motor 14
Only the first ON period is taken for a long time to some extent, and thereafter, a fixed cycle / ON / O as shown in the first embodiment is taken.
Even if the operation of the FF constant ratio is continuously performed, the effect of the present invention is achieved.
