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

As shown in the figure, a main body 2 of a ventilation dryer attached to a ceiling of a bathroom 1 is provided with a first suction port 3 communicating with the bathroom 1 and a discharge port 4 communicating with the outside of the room.
A first blower 6 for intermittent ventilation is provided, and a heating means 7 comprising a heater for circulating and warming the air in the bathroom 1 is provided at a second discharge port 8 communicating with the interior of the bathroom 1. bathroom 1 humidity detecting means 9 for detecting the absolute humidity
A second blower 11 provided in a second suction port 10 communicating with the
The signal from the humidity detecting means 9 is inputted, and the judging means 13 for judging that the bathroom 1 or the drying object 12 such as the laundry suspended in the bathroom 1 is dried and stopping the operation of the ventilation blower is provided. It is provided and configured.

The operation of the ventilation dryer configured as described above will be described with reference to FIG. When the ventilation dryer is operated, the second blower 11 operates and is heated by the heating means 7 while circulating the air in the bathroom 1, so that the circulating air comes into contact with the drying object 12 in the bathroom 1. When the circulating air is brought into contact with the material to be dried 12 moisture evaporates, absolute humidity in the bathroom 1 increases. On the other hand, from the start of operation of the ventilation dryer by the timer means 5,
The times T ₁ and T ₂ are counted, and at the time T ₂ , the first blower 6 is operated to ventilate. Absolute humidity is discharged air moist in the bathroom 1 by the ventilation effect decreases rapidly. Thus Doing ventilation intermittent absolute humidity increases, as in FIG. 3, continue to decrease while repeatedly increasing the reduction, the material to be dried 12 is eventually dries, when stopped ventilation When the absolute humidity is equal to or less than the drying determination level Z ₀ , the determination unit 13 determines that the absolute humidity is equal to the drying determination level Z.
Judging that it has become ₀ or less, the operation of the ventilation dryer is stopped. As described above, according to the ventilation dryer of the first embodiment of the present invention, the absolute humidity in the bathroom 1 is reduced while greatly changing by operating the first blower intermittently to ventilate the air. In the case where the air is driven and ventilated, the absolute humidity when the object 12 is dried hardly changes, but it is possible to reliably and easily determine that the object 12 is dried.

Next, a second embodiment of the present invention will be described. In the second embodiment, the judgment means is different from that of the first embodiment. In the first embodiment, the absolute humidity when the ventilation operation is stopped is detected by the humidity detection means 9 and the judgment means 1
3, the end of the drying is determined based on the magnitude relationship with the drying determination level Z ₀ , whereas in the second embodiment, the relative humidity is detected by the humidity detecting means 9 and the gradient of the relative humidity before and after the ventilation operation is determined. The determination means 13 is configured to determine the end of the drying from the change.

The operation of the ventilation dryer configured as described above will be described with reference to FIG. When the ventilation dryer is operated, the first blower 6 is operated intermittently to ventilate the air containing moisture in the bathroom 1 as in the operation of the first embodiment, and the relative humidity detected by the humidity detecting means 9 is as shown in FIG. Increase,
It decreases while repeating the decrease, and eventually the material to be dried 1
When 2 is dried, the gradient of the relative humidity before and after the ventilation operation approaches from zero to zero as shown in FIGS. Then, the judgment means 13 judges when the gradient of the relative humidity detected by the humidity detection means 9 has approached zero from minus and stops the operation of the ventilation dryer.

As described above, according to the ventilation dryer of the second embodiment of the present invention, it is possible to reliably determine the difference in relative humidity between before and after the dried object 12 is dried, and It is possible to reliably and easily determine that the object 12 has dried.

Next, a third embodiment of the present invention will be described. The third embodiment is intended judgment means is different from the second embodiment, in the second embodiment is detected by the humidity detecting means 9,
The determination means 13 determines the end of drying from the change in the gradient of the relative humidity before and after the ventilation operation.
In the embodiment, the determination means 13 is configured to compare the relative humidity during and after ventilation to determine the end of ventilation.

The operation of the ventilation dryer configured as described above will be described with reference to FIG. When the ventilation dryer is operated, the first blower 6 is operated intermittently to ventilate the air including moisture in the bathroom 1, and the relative humidity detected by the humidity detecting means 9 is reduced. When the material to be dried 12 dries, as shown in FIG. 5, the relative humidity H ₁ in ventilation
And the relative humidity of H ₂ after ventilation are substantially equal. The judging means 13 judges this state and stops the operation of the ventilation dryer.

As described above, according to the ventilation dryer of the third embodiment of the present invention, the fact that the object to be dried 12 is dried can be reliably determined by the relative humidity before and after the object to be dried 12 is dried. , And can be easily determined.

[0019]

As apparent from the above embodiment according to the present invention, with a With if intermittent ventilation the present invention detects the humidity of the circulating air in the room, since it is determined the degree of dryness, changes in room humidity
