(12) is a course setting means, which includes a "warm air" course that only dries the futon (9), an "automatic air blow" course that cools down the futon (9) by blowing air after the futon is dry, etc. (not shown). ing. A futon drying time for drying the futon (9) with hot air and an air blowing time for cooling the futon (9) with air are set in advance. However, the futon drying time can also be set manually. In addition, the temperature of the hot air when drying the futon (9) is set according to the material of the futon (9), and when the futon (9) is made of feathers or wool, it is set to 50°C.
In the case of cotton, the temperature is set at 65° C., and a temperature command corresponding to the set temperature is sent to a hot air control means (13) to be described later.

These temperatures are based on the selection of the operating keys of the operating means (11) mentioned above.

In addition, when the above-mentioned hot air exceeds the upper limit temperature, it is due to a backflow of hot air that occurs when the mat (8) is crushed or the hose (7) is clogged with something.

Next, the operation will be explained based on FIGS. 4 and 5. When a driving key is selected with the operating means (1) and a course is then set with the course setting means (12) (Sl), the course setting means (12) selects the driving key of the operating means (11).

The hot air control means (13) into which the temperature command has been input controls the heating amount control means (14) and the air blowing control means (15) to heat the heater (2) and operate the fan (3) to raise the temperature. Generate wind and start drying the futon (9). At this time,
The hot air control means (13) controls the heating amount control means (14) so that the generated hot air has the same temperature as the temperature set by the course setting means (12). Then, when the count time is up (S5), the course setting means (12) determines whether the course is "warm air" or "automatic air blowing" (S6), and in the case of "warm air", A control stop command is issued to the hot air control means (13) (S7) to stop the futon dryer main body (1) and finish drying the futon (9). By setting this course, the temperature characteristics as shown in FIG. 6 are obtained.

In addition, when the course set by the course setting means (12) is "automatic fan", the heater (2)
A command to stop the air flow is issued to the hot air control means (13) (S8), and the air blowing time is set and counting of that time is started (S9). At this time, the heater (2) is stopped and only the fan (3) continues to operate to cool the futon (9). When the count time times up (sio), the course setting means (12) issues a command to the hot air control means (13) to stop the fan (3) and stops the futon dryer main body (1) (Sll), Finish the operation.

At this time, the temperature characteristics are as shown in FIG.

When the upper limit temperature determining means A (18) or the upper limit temperature determining means B (20) detects a temperature exceeding the upper limit temperature while drying the futon, an upper limit temperature detection signal is sent to the hot air control means (13). The hot air control means (13) into which the detection signal has been inputted controls the superheat amount control means (14) and the air blowing control means (
15) and stop the operation of the heater (2) and fan (3).

[Problems to be Solved by the Invention] In recent years, an increasing number of users are drying the futon (9) before going to bed. According to sleep physiology, the bed temperature varies slightly from person to person, but it is 5℃ to 1℃ lower than body temperature (approximately 36℃).
It is said that a temperature as low as 0°C is a comfortable place to sleep. In order to obtain this bed temperature with a conventional futon dryer, when the room temperature is between 26℃ and 31℃, operation using the above-mentioned "automatic ventilation" is suitable, but when the room temperature is other than that, It was difficult to meet the conditions. For example, room temperature or 10℃,
In the case of 20℃, as shown in Figure 7, the temperature is almost the same as the room temperature due to the air blowing after the futon drying, so a comfortable bed temperature cannot be obtained, and if only the futon is dried.
When the futon dryer body (1) was operated with "warm air", the temperature characteristics were as shown in Figure 6, and the dryer was not ready to be put on the floor. In such a case, in order to remove the hot air from the futon (9), you can use the "blow" mode to cool it down.
There were various problems such as the work of lifting the futon (9) and removing the hot air.

This invention was made to solve this problem, and an object of the present invention is to provide a futon dryer that can provide a bed temperature that meets the user's needs without being affected by room temperature.

[Means for Solving the Problems] The futon dryer according to the second invention includes a plurality of selection switches provided according to the material of the futon, a course selection switch having at least an automatic warm air course, and a plurality of control temperature controls. A control temperature selection switch is provided corresponding to each of the plurality of control temperature selection switches, and a temperature corresponding to each of the plurality of selection switches is set, and a control temperature lower than the set temperature is set corresponding to the plurality of control temperature selection switches. When the respective set temperature setting means and the course selection switch are set to the automatic hot air course, and any one of the plurality of control temperature selection switches is selected,
The temperature of the temperature setting means corresponding to the material of the futon selected by the selection switch is sent as a reference temperature for a predetermined period of time, and after the elapse of the predetermined period, the control temperature selected by the control temperature selection switch is set as the reference temperature. The apparatus includes a temperature control means for sending out air, and a hot air control means to which a reference temperature from the temperature control means is input and which controls heating of a heater and operates a fan using the reference temperature as a reference value.

[Operation] In this invention, when the selection switch corresponding to the material of the futon to be dried is selected, the automatic hot air course is set using the course selection switch, and any one of the plurality of control temperature selection switches is selected. , the temperature control means are
The temperature selected by the selection switch is read from the temperature setting means, and the temperature is sent to the hot air control means as a reference temperature for a predetermined period of time. The hot air control means that receives the reference temperature heats the heater using the reference temperature as a reference value, and also operates the fan to generate warm air and dry the futon. When the predetermined time set in the temperature control means expires while the futon is drying, the temperature control means reads the control temperature selected by the control temperature selection switch from the temperature setting means, and uses the control temperature as the reference temperature to start the hot air. Send to control means. The hot air control means that controls the heater and fan to generate hot air uses the reference temperature of the control temperature as a reference value, and controls the heater so that the temperature of the hot air during futon drying becomes the same as the reference value. control.
