Description

[Detailed Description of the Invention] This invention relates to a timer device used in a dryer such as a futon dryer.

A conventional futon dryer is shown in FIGS. 1 and 2.

In the figure, 7 is a hot air generator that includes a blower 8 and a heater 9, 10 is a hose that is separably connected to the outlet 8a of the blower 8, and 11 is a cloth bag-shaped tube that is connected to the tip of the hose 10. This is a futon drying attachment that is inserted between the three futons.

Therefore, when the hot air generator 7 is operated, the hot air generated by the blower 8 and the heater 9 and discharged from the outlet 8a flows into the futon drying attachment 11 via the hose 10.

Next, the hot air flowing out from the surface of the futon drying attachment 11 is released into the atmosphere through the futon S, and at this time,
The moisture contained in the futon S is removed by the hot air, and the futon S is dried.

Reference numeral 12 denotes a timer for controlling the time during which the blower 8 and heater 9 are energized, and has an operation knob 12a.

Reference numeral 13 denotes a changeover switch, which has a stop position in which neither the blower 8 nor the heater 9 is energized, a cold air position in which only the blower 8 is energized, and a hot air position in which both the blower 8 and the heater 9 are energized.

In the configuration as described above, the changeover switch 1
When the operation knob 13a of No. 3 is set to the hot air position and the timer 12 is set to a predetermined time, the blower 8 and heater 9 are operated to dry the futon S as described above.

Particularly in summer, the futon S gets hot after drying and it is difficult to sleep comfortably on a hot futon S. Therefore, cold air is sent into the futon drying attachment 11 to dry the futon S.
It is best to cool it down.

In this case, if the operation knob 13a of the changeover switch 13 is set to the cold air position and the timer 12 is set to a predetermined time, only the blower 8 will operate, thereby causing the hose 1
0 into the futon drying attachment 11 to cool the futon S.

In this way, in the conventional futon dryer, the selector switch 13 is set to the hot air or cold air position, and the timer 1 is set to the hot air or cold air position.
2 has to be set at a predetermined time, which makes the operation very cumbersome. Also, especially in the summer, when you want to cool the futon S with cold air after the futon S has finished drying with hot air, you can use hot air to cool the futon S. When the futon drying is finished, it is necessary to return to the futon dryer to set the changeover switch and timer again, which is extremely time-consuming.

This invention was made in response to these conventional circumstances, and aims to provide a dryer timer device that is easy to operate, has a simple structure, and can be manufactured at low cost. The details will be explained below with reference to an example implemented in a futon dryer.

In the description, the same reference numerals are given to the same parts as those of the conventional one.
