[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device.

[0002]

2. Description of the Related Art A conventional lifting device of this kind is known as
There is one disclosed in Japanese Patent No. 51866, and as shown in FIG. 6, a storage cabinet 1 fixed to a wall surface 15, a drier 2 in the storage cabinet 1, and a drier 2 are moved up and down by a wire 8. A drive unit 3 for driving the dryer 2, a drive controller 4 for controlling the raising and lowering of the dryer 2, and an operation switch 6 for raising, lowering, and stopping the dryer 2 are provided outside the storage cabinet 1. Has a structure in which hot air is sucked in through the air inlet 11 on the bottom surface, and hot air is blown into the storage of the dryer 2 through the air outlet 12 by the warm air device 9 and exhausted from the upper front portion of the dryer 2.

[0003]

With such a conventional structure, when the dryer 2 is operated while being housed in the storage cabinet 1, high temperature and high humidity exhaust gas from the dryer 2 is stored in the storage cabinet 1. As it fills up, electrical circuit parts and various mechanical parts malfunction due to condensation and shorten the service life, and the storage cabinet 1 is kept in high humidity for a long time, and mold on the storage cabinet 1 inner wall. There was a problem of breeding and deterioration of the material of the storage cabinet.

The present invention solves such a problem, and an object thereof is to discharge the exhaust air from the dryer to the outside of the storage cabinet so as not to fill the inside of the storage cabinet.

[0005]

SUMMARY OF THE INVENTION An elevating and lowering device of the present invention is a storage cabinet having a downward opening, a drier capable of moving up and down in the storage cabinet, a drive device for raising and lowering the drier, and a driving device for driving the drier. A drive control device for controlling the device and an exhaust device for discharging the air in the storage cabinet to the outside of the storage cabinet are provided.

[0006]

Since the lifting device according to claim 1 of the present invention is provided with the exhaust device for discharging the air in the storage cabinet to the outside of the storage cabinet, the high temperature and high humidity exhaust air from the dryer is filled in the storage cabinet. It is possible to prevent dew condensation in the electric circuit section and each mechanism section that causes malfunction and shorten the life, and suppress the propagation of mold on the inner wall of the storage cabinet and the deterioration of the material of the storage cabinet. Further, since the elevating device according to claim 2 is provided with the exhaust control device which is electrically linked to the start-stop device of the dryer and controls the exhaust device, the start-up and stop of the dryer are determined and the operation is followed. By starting and stopping the exhaust system, the exhaust can be automatically operated. Further, since the lifting device according to claim 3 is provided with a sensor for detecting the state of the exhaust gas from the dryer in the storage cabinet, and an exhaust control device for electrically controlling the exhaust device in an electrically linked manner with the sensor, the high temperature and high temperature. When it detects the exhaust of moisture, it can automatically perform the exhaust operation.

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

In FIG. 1, a storage cabinet 1 having an opening at the bottom is fixed to a wall surface 15. Inside the storage cabinet 1, a dryer 2 and a drive device 3 for moving the dryer 2 up and down
And a drive control device 4 and an exhaust device 5 for controlling the drive device 3.
Distribute. The drive device 3 and the drive control device 4 are fixed to a top plate in the storage cabinet 1. The dryer 2 is connected to the driving device 3 by the wire 8 and can be moved up and down by the driving device 3. The exhaust device 5 is configured to exhaust the air in the storage cabinet 1 to the outside from the exhaust port 7 by a sirocco fan. The dryer 2 sucks air from an intake port 11 on the bottom surface and sends hot air into the inside of the dryer 2 by a warm air device 9 to exhaust the hot air from the upper front part of the dryer 2. When the dryer operation switch 10 is turned on, a drying operation is performed. Is started and automatically stopped after the set time. On the front surface of the storage cabinet 1, an operation switch 6 having a switch for raising, lowering and stopping the dryer 2 and a switch for starting and stopping the exhaust device 5 is provided.

In the above structure, since the top panel in the storage cabinet 1 is provided with the exhaust device 5, the exhaust of high temperature and high humidity from the dryer 2 can be discharged to the outside of the storage cabinet.

Next, another embodiment of the present invention will be described. 2 and 3 show another embodiment. In this embodiment, the current transformer 18 monitors the energization of the hot air device 9 so that the signal judging circuit 16 in the exhaust control device 13 causes the dryer 2 to operate. Of the exhaust device 5 is determined by the ON-OFF control circuit 17 according to the timing of determining whether to start or stop
As a result, the exhaust operation can be automatically performed only by pressing the start switch of the dryer 2, and the exhaust operation can be ended when the drying is completed.

FIGS. 3 and 4 show another embodiment. In this embodiment, a temperature sensor 14 is provided below the exhaust device 5 in the storage cabinet 1 and its output signal is taken into the exhaust control circuit 13 for temperature control. The exhaust device 5 is started up when the exhaust gas temperature of the dryer 2 rises by monitoring the change of the temperature change, and the exhaust device 5 is stopped when the temperature returns to normal. As a result, the dryer 2 is started up. By simply pressing a switch, the exhaust operation can be automatically performed, and the exhaust operation can be ended when the drying is completed.

Although the temperature sensor is used in the above embodiment, the present invention is not limited to this, and the effect of the present invention can be achieved by using a humidity sensor instead of the temperature sensor to monitor a change in humidity. To do.

[0013]

As is apparent from the above description of the embodiments, the following effects are exhibited. Since the lifting device according to claim 1 of the present invention is provided with the exhaust device for discharging the air in the storage cabinet to the outside of the storage cabinet, the high temperature and high humidity exhaust from the dryer does not fill the storage cabinet. In addition, it is possible to prevent dew condensation in the electric circuit section and each mechanism section which causes malfunction and shorten the life, and suppress the propagation of mold on the inner wall of the storage cabinet and the deterioration of the material of the storage cabinet. Further, since the elevating device according to claim 2 is provided with the exhaust control device which is electrically linked to the start-stop device of the dryer and controls the exhaust device, the start-up and stop of the dryer are determined and the operation is followed. By starting and stopping the exhaust system, the exhaust can be automatically operated. Further, since the lifting device according to claim 3 is provided with a sensor for detecting the state of the exhaust gas from the dryer in the storage cabinet, and an exhaust control device for electrically controlling the exhaust device by electrically connecting with the sensor.
When the exhaust of high temperature and high humidity is detected, the exhaust operation can be automatically performed.
