Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dryer for clothes, tableware, cutting boards, fluffies, knives and the like.

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional dryer of this type has a drying chamber 1 for storing and drying tableware and the like, and a drying chamber 1 for drying the same.
A warm air device 4 including a heater 2 for supplying warm air and a fan motor 3 for blowing air, and a controller 5 for controlling the warm air device 4 are provided. After the stop, only the fan motor 3 for blowing air was driven for a certain period of time.

[0003]

In such a conventional structure, the air blown for cooling the drying chamber 1 after completion of the drying is carried out by using the same fan motor 3 and the same number of revolutions as during the drying. Therefore, the driving time of the fan motor 3 in one drying operation becomes long, and the life of the fan motor adversely affects the life of the dryer itself, as compared with a dryer that does not blow air for cooling. There is a problem that the noise caused by the rotation of the motor 3 is prolonged.

The present invention has been made to solve the above problems and has an object to improve the life of the dryer and reduce noise during operation.

[0005]

The dryer of the present invention has a drying chamber for storing and drying tableware and the like, an intake path for taking in outside air into the drying chamber, and hot air or air is supplied into the drying chamber. Heater and a fan motor for blowing air, a blowing path for sending the air generated by the warm air device into the drying chamber, and an exhaust for exhausting the warm air circulated in the drying chamber. A control unit for controlling the path, the heater and the fan motor in the warm air device, and driving only the fan motor at a lower rotational speed than during drying is provided after completion of drying.

[0006]

Since the dryer of the present invention is provided with the control unit for driving the air blow for cooling the drying chamber after completion of the drying at a lower rotation speed than during the drying, the fan motor in one drying operation is provided. The load on the dryer is reduced, the life of the dryer itself is positively affected, and the number of rotations is reduced,
The noise due to the wind noise of the fan motor is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG.
-It demonstrates, referring FIG.

In the figure, reference numeral 6 denotes a dryer main body, which is a dryer 6
A drying chamber 7 for storing and drying tableware and the like, an intake path 8 for taking in outside air into the drying chamber 7, a heater 9 for supplying warm air and air into the drying chamber 7, and a fan for blowing air. A warm air device 11 including a motor 10 and a ventilation path 12 for sending the air generated by the warm air device 11 into the drying chamber 7.
The exhaust path 13 for exhausting the warm air circulated in the drying chamber 7, the heater 9 and the fan motor 10 in the warm air device 11 are controlled, and after the drying is completed, only the fan motor 10 is lower than during the drying. The control unit 14 is driven by the number of rotations (the arrow in the figure represents the flow of air).

In the above structure, the fan motor 10 in one drying operation is provided because the controller 14 is provided to drive the air for cooling the drying chamber 7 after the drying at a lower rotation speed than during the drying. The burden on
The life of the dryer 6 itself is positively affected, and the rotation speed is reduced, so that noise due to wind noise of the fan motor 10 is reduced.

Next, a second embodiment of the present invention will be described. 2 to 3 show a second embodiment. In this embodiment, the auxiliary fan motor 15 whose rotation speed is set lower than that of the fan motor 10 in the warm air device 11 and the auxiliary fan motor 15 generate the same. The auxiliary air passage 16 communicating with the drying chamber 7 different from the air passage 12 of the warm air device 11 for sending the air into the drying chamber 7, the auxiliary fan motor 15, and the warm air device 11
The heater 9 and the fan motor 10 in the inside are controlled to drive the heater 9 and the fan motor 10 in the warm air device 11 at the time of drying, and the sub fan motor 1 in the sub air passage 12 after the drying is completed.
5, a controller 17 for driving only 5 is provided (in the figure, the solid line arrow indicates the air flow during drying, and the dotted line arrow indicates the air flow after drying). As a result, the fan motor in one drying operation is shown. The load on 10 is reduced, which has a positive effect on the life of the dryer 6 itself, and the auxiliary fan motor 15
Since the rotation speed of is lower than that during drying, noise due to wind noise of the fan motor 15 is reduced.

Next, a third embodiment of the present invention will be described. 5 to 6 show a third embodiment, in which a deodorizing device 18 for adsorbing and decomposing odors in an exhaust passage 13 for exhausting the air circulated in the drying chamber 7 and a warm air device 11 for drying are provided. The controller 9 for driving the heater 9 and the fan motor 10 therein and, after the drying is completed, driving the auxiliary fan motor 15 for a certain period of time for cooling the drying chamber 7 and intermittently controlling the driving thereafter.
(The solid line arrow in the figure indicates the
Also, the dotted arrow indicates the flow of air after the end of drying). With the above configuration, the air containing odor generated from stored items such as tableware and cutting boards in the drying chamber passes through the deodorizing device 18 in the exhaust path 13. The odor deodorized and discharged from the dryer 6 is reduced. After the drying is completed, the auxiliary fan motor 15 is driven for a certain period of time to cool the drying chamber 7 and is also intermittently driven thereafter. It can be taken out, and the discomfort caused by the odor in the drying chamber when taking out the stored item 19 is reduced. Moreover, the fan motor 1 when dry
Since the auxiliary fan motor 15 whose rotational speed is lower than 0 is driven, the load on the fan motor 10 in one drying operation is reduced, which has a favorable effect on the life of the dryer 6 itself.
The noise due to the wind noise of the auxiliary fan motor 15 is reduced.

In the above embodiment, the fan motor driven after the completion of drying is the auxiliary fan motor 15 different from that used during drying.
However, the present invention is not limited to this, and the effect of the present invention can be achieved by driving the same fan motor as in the first embodiment at the time of drying at a low rotational speed.

[0013]

As is apparent from the above description of the embodiments, according to the present invention, the fan motor is driven at a lower rotation speed than that at the time of drying for blowing air for cooling the drying chamber after completion of drying. Since the control unit is provided, the load on the fan motor in one drying operation is reduced, which has a favorable effect on the life of the dryer itself, and the rotation speed becomes low. This has the effect of reducing noise caused by the above.
