As shown in FIG. 8, input means such as a foot pedal switch 7, a heater switch 8, and an air volume change switch 9 are connected to the input side. On the output side, output means such as the electric motor 21 of the blower 3 and the heater wire 6 are connected. Further, a household power source is connected to the control unit 60, and power from the power source is supplied to the electric motor 21 and the heater wire 6 via the control unit 60.

  The control unit 60 includes motor control means 61 and temperature control means 62 as internal functions. The motor control means 61 controls the rotation of the electric motor 21 and controls the speed at which the expansion / contraction part 4 is expanded and contracted and the flow rate / flow velocity of the air blown from the blowing part 5. A process for controlling the heating temperature of the air by controlling the heat generation amount is performed.

  Next, the operation of the body dryer 1 having the above configuration will be described.

  When the foot dryer 7a is stepped on and the foot pedal switch 7 is turned on to start using the body dryer 1 with the body dryer 1 placed on the floor G, the motor control means 61 of the control unit 60 is turned on. Supplies electric power to the electric motor 21 of the blower 3 to drive the electric motor 21 and rotate the axial fan 22.

  And by rotation of the axial fan 22, external air is taken in into the housing | casing 11 of the base 2 from the inlet 14, and is sent from the ventilation chamber 2A to the storage chamber 2C via the heating chamber 2B.

  The air sent to the storage chamber 2C by the blower 3 is filled in the cylindrical body 30 of the telescopic portion 4 in the storage chamber 2C, and the first cylindrical body 31 to the first cylindrical body 30 are increased by the increase in the internal pressure in the cylindrical body 30. The cylindrical body 34 is moved upward to be connected in the axial direction, and the expansion / contraction part 4 is extended from the base part 2 upward, and is blown out from the blowing part 5.

  As shown in FIG. 9, the motor control means 61 performs start-up control that gradually increases the rotation speed of the electric motor 21 during the start-up control time Ta by turning on the foot pedal switch 7, and is sent into the storage chamber 2 </ b> C. The amount of air is gradually increased, and the expansion / contraction part 4 is smoothly extended.

  Then, when strong wind is selected by the air volume changeover switch 9, the rotation speed of the electric motor 21 is adjusted to a preset high speed rotation speed to increase the air volume blown from the blowing section 5, and the weak wind is generated. If selected, the rotational speed of the electric motor 21 is adjusted to a preset low-speed rotational speed to reduce the amount of air blown from the blow-out unit 5.

  When the warm air is selected by the heater switch 8, the temperature control means 62 energizes the heater wire 6, heats the heater wire 6 and heats the air passing through the heating chamber 2B, and the blowing unit When hot air is blown from 5 and air blowing is selected by the heater switch 8, the heater wire 6 is not energized, and the air taken in from the intake port 14 is blown out from the blowing portion 5 as it is.

  Further, the suction cup 51 of the fixing means 50 is adsorbed to the floor G using the negative pressure generated in the blower chamber 2 </ b> A by the rotation of the axial fan 22, the base 2 is fixed to the floor G, and the blower 5 The body dryer 1 is prevented from being tilted due to the reaction of the blown air.

  When the foot pedal 7a is stepped on and the foot pedal switch 7 is turned off to stop the use of the body dryer 1, the motor control means 61 of the control unit 60 stops the rotation of the electric motor 21 and blows the blower. 3 is stopped. Thereby, the internal pressure in the cylindrical body 30 is reduced, the first cylindrical body 31 to the fourth cylindrical body 34 are moved downward by their own weight, the expansion / contraction part 4 is contracted, and the housing 11 is accommodated. Housed in part 2C.

  As shown in FIG. 9, the motor control means 61 performs rotation stop control that gradually decreases the rotation speed of the electric motor 21 during the rotation stop control time Tc, and gradually decreases the internal pressure in the cylindrical body 30. The elastic part 4 is contracted smoothly. When warm air is selected by the heater switch 8, the electric motor 21 continues to rotate until the preset heater cooling time Tb elapses after the foot pedal switch 7 is turned OFF, thereby cooling the heater. After the time Tb elapses, the rotation stop control is performed to stop the rotation of the axial fan 22.

  According to the body dryer 1 having the above-described configuration, the stretchable portion 4 can be extended upward from the base portion 2 and air can be blown out from the blowout portion 5 to the top and bottom of the stretchable portion 4. Therefore, air can be simultaneously blown over the object over a predetermined height range.

  Therefore, for example, even in a narrow place, as shown in FIGS. 10 and 11, when the user stands at the side position of the body dryer 1, air blow and warm air can be simultaneously performed in the longitudinal direction of the user's body. The body can be efficiently cooled or dried.

  And the expansion-contraction part 4 can be contracted by the ventilation stop of the air blower 3, and the expansion-contraction part 4 can be accommodated in the housing | casing 11 of the base 2, as shown in FIG. Therefore, the size of the entire apparatus when not in use can be reduced, and it does not get in the way. And it can be installed in a narrow place and can be moved easily.

  Moreover, the lower end part of the cylindrical body 30 arrange | positioned inside in the expansion | extension state among the some cylindrical bodies 30 is latched by the upper end part of the cylindrical body 30 arrange | positioned outside, and an upper end part and a perimeter Since the airtight sealing is performed so that air does not leak from the upper end portion, the expansion / contraction part 4 can be reliably extended. Air can be blown out without leakage.

  Further, the suction cup 51 of the fixing means 50 is adsorbed to the floor surface G with a predetermined adsorbing force using the negative pressure generated in the air blowing chamber 2A of the base portion 2 by the rotation of the axial fan 22, and the base portion 2 is brought to the floor surface. G can be fixed. Therefore, it is possible to effectively prevent the body dryer 1 from being tilted by the reaction of the air blown out from the blow-out portion 5 or the like. Since the negative pressure in the blower chamber 2 disappears due to the rotation of the axial fan 22 being stopped, the suction force of the suction cup 51 can be eliminated, and the body dryer 1 is lifted from the floor G and moved easily. Can be made.

  In the above-described embodiment, a case has been described in which the cylindrical body disposed on the upper side in the expanded state has a small diameter and the cylindrical body disposed on the lower side has a large diameter. The cylindrical body to be formed may have a large diameter, and the cylindrical body disposed on the lower side may have a small diameter.
