In the figure, (1) is a futon dryer body, (2) is a heater, (3) is a fan, (4) and (5) are thermistors,
The thermistor (4) is installed in the air path (6),
The thermistor (5) is installed near an opening (not shown) provided on the side wall of the air path (6). (7) is a bellows-shaped telescopic hose, (8) is a mat,
(9) is a futon.

(11) is an operation means for operating a "feather / wool" key, a "cotton" key, a "stop" key for stopping the futon dryer body (1) (not shown), etc., according to the material of the futon (9). And sends a signal corresponding to the key selection to a course setting means (12) to be described later.

(12) is a course setting means, which is provided with a "warm air" course only for drying the futon (9), an "automatic blast" course for blowing the futon (9) after the futon is dried, and the like (not shown). ing. The futon drying time when the futon (9) is dried with warm air and the blast time when the futon (9) is cooled by blowing air are set in advance. However, the futon drying time can be manually changed. The temperature of the hot air during the drying of the futon is set according to the material of the futon (9). A temperature command corresponding to the set temperature is sent to the hot air control means (13). These temperatures are based on the selection of the operation key of the operation means (11) described above.

(13) is hot air control means, which controls the heating amount control means (14) to heat the heater (2) and controls the air blowing control means (15) based on a command from the course setting means (12). Then, the fan (3) is operated to generate hot air. At the same time, the heating amount control means (14) is controlled so as to have the same temperature as the temperature set by the course setting means (12).

(16) is an air temperature measuring means for measuring a voltage based on the resistance value of the thermistor (4) obtained corresponding to the hot air temperature of the air path (6). (17) is a wind temperature determining means for determining the temperature of the hot air in the air path (6) based on the voltage measured by the wind temperature measuring means (16). (18) is an upper limit temperature judging means A in which an upper limit of the hot air temperature is set, which operates when the hot air temperature based on the measurement voltage of the wind temperature measuring means (16) is higher than the upper limit temperature, The upper limit temperature detection signal is sent to (13).

(19) is an upper limit temperature measuring means for measuring a voltage corresponding to the resistance value of the thermistor (5) in the same manner as the wind temperature measuring means (16). (20) is an upper limit temperature determining means B in which the upper limit of the temperature in the futon dryer body (1) is set, and operates when the temperature based on the voltage measured by the upper limit temperature measuring means (19) is higher than the upper limit temperature. Then, an upper limit temperature detection signal is sent to the hot air control means (13).

The reason why the above-mentioned temperature exceeds the upper limit temperature is due to the backflow of hot air that occurs when the mat (8) is crushed or the hose (7) is clogged with an object.

The case where the futon (9) is warmed in the conventional futon dryer configured as described above will be described. Operating means (1
In 1), select one of the operation keys of “feather / wool” or “cotton”, and then use the course setting means (12) to select “hot air”.
When the course is selected and the futon drying time is manually set to an appropriate time, the hot air control means (13) communicates with the heating amount control means (14) based on the temperature command of the course setting means (12). The control means (15) is controlled to operate the heater (2) and the fan (3) to generate warm air. Although it depends on the room temperature, the temperature of the hot air rises with the passage of time and reaches a predetermined temperature (based on the operation selected by the operation means (11)) corresponding to the material of the futon (9). warm. At this time, the temperature of the hot air is kept constant by the feedback control of the air temperature determining means (17). When the time set in the course setting means (12) expires, the course setting means (12) sends a control stop command to the hot air control means (13), and the heater (2) and the fan (3) To stop. As a result, the futon (9) is warmed without being heated.

[Problems to be Solved by the Invention] As described above, since the conventional futon dryer does not have a function of heating the futon (9), the "hot air" course of drying the futon (9) with hot air is used. The setting had to warm the futon (9). In this case, the user adjusts the temperature of the futon (9) by setting in consideration of the futon drying time. However, if the time is incorrectly set, the futon (9) is too hot or is not warmed up. In addition, there was a problem that a comfortable bed temperature could not be obtained because the futon dryer main body (1) stopped.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a futon dryer having a function of automatically warming a futon without relying on a user's intuition.

[Means for Solving the Problems] A futon dryer according to the present invention drives a fan and heats a heater with a constant heating amount to generate hot air at a predetermined temperature, and dries the futon with the hot air.

Insulation temperature setting means and, when the rising heating time is set by the heating time setting means, the fan is driven, and the heater is heated with a constant heating amount. When the temperature has passed, the heating temperature of the heater is controlled so as to reach the heat retention temperature set by the heat retention temperature setting means, and warm air control means for warming the futon is provided.

[Operation] In the present invention, when the room temperature detecting means detects the room temperature, the heating time setting means sets the rising heating time which is inversely proportional to the room temperature, and the warming temperature setting means detects the temperature by the room temperature detecting means. It is determined which of the plurality of preset temperature ranges the room temperature is in, and a heat retention temperature is selected from the result. For example, when the room temperature is in the high temperature region, a low heat retention temperature is selected, and when the room temperature is in the low temperature region, a high heat retention temperature is selected. When the rising time is set by the heating time setting means, the hot air control means drives the fan and heats the heater with a constant heating amount.When the rising heating time has elapsed,
The amount of heating of the heater is controlled so as to reach the heat retention temperature set by the heat retention temperature setting means, thereby heating the futon.
