    Conventionally, bean charcoal anchors, hot water bottles, electric blankets, etc. have been used for heating bedding duvets at bedtime, but bean charcoal anchors, hot water bottles, etc., are naturally radiated, and the heat radiation range is narrow, and electric blankets are hanging or laid. However, there was a problem that the warmth could not reach the entire space between the comforter and the mattress, and it was only possible to heat either the front or back of the human body.

    The present invention provides a heater case in which a main body forms a square lattice frame, a substantially rectangular parallelepiped with a large number of ventilation holes, and a power operation device is attached to one side of the side, and a motor is attached to the outer upper center of the heater case. An annular warm air discharge plate with a curved edge is attached to the inside of the heater case, and a sirocco fan is attached to the motor at the lower part so that it can rotate. A halogen heater is installed, and the heat released from the halogen heater is concentrated on the annular warm air discharge plate. The warm air of the annular warm air discharge plate is directed downward, and the sirocco fan releases a wide annular and warm air around it. The purpose is to provide hot air kotatsu for bedding.

    In order to achieve the above object, a heater case in which the body is a square lattice frame, a substantially rectangular parallelepiped with a large number of ventilation holes on the surface, and a power switch and a temperature control knob on one side of the side surface. An annular hot air discharge plate that covers the motor with a motor cooling fan at the center of the outer upper part of the heater case, covers the motor with the motor case, and forms the edge of a disk with one side bent inside the heater case. The sirocco fan is pivotally attached to the motor at the lower part of the annular hot air discharge plate, a heater installation plate is provided at the lower part of the heater case, and a means of attaching a halogen heater to the heater installation plate is taken.

    In addition, heat is immediately released from the halogen heater, and the increased heat is concentrated on the annular hot air discharge plate. The warm air of the annular hot air discharge plate is directed downwards, and the sirocco fan spreads the warm air to the surroundings with an annular discharge. It is preferable that it can be released into the inside.

    Moreover, you may make a halogen heater into arbitrary shapes.

    And as a heater, a quartz tube or a carbon heater can also be used and you may make it become arbitrary shapes.

    Furthermore, it is preferable that an abnormal heating safety device is provided in the halogen heater, the motor, and the annular hot air discharge plate, and the device is activated and automatically stopped when abnormal.

    With conventional bedding or anchors for bedding, natural heat is dissipated from the heater that is the heat source, and the air heated in the comforter and mattress concentrates upward, and the warmth does not reach the entire space between the comforter and mattress However, in the hot air kotatsu for bedding according to the present invention, a heater case having a substantially rectangular parallelepiped shape with a large number of ventilation holes and a power operation device on one side is provided inside the lattice frame of the main body. A motor is attached to the center of the upper part, a warm air ring discharge plate with a curved disc edge is attached to the inside of the heater case, a sirocco fan is pivotally attached to the motor at the lower part, and a heater installation plate at the lower part A halogen heater is installed, and the heat released from the halogen heater is concentrated on the annular hot air discharge plate, and the warm air on the annular hot air discharge plate is directed downwards. Those capable of releasing warm air widely annularly around the emissions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to the drawings.
In the embodiment shown in FIGS. 1 to 2, the main body 1 is a square lattice frame 2, and the lattice frame 2 has a substantially rectangular parallelepiped with a large number of air holes 3 on the surface, and a power switch 4 on one side of the side surface. A heater case 6 with a temperature control knob 5 is provided, and a motor 8 provided with a motor cooling fan 7 is covered with the motor case 9 at the center of the outer upper part of the heater case 6, and one side is placed inside the heater case 6 which is the lower part of the motor 8. An annular warm air discharge plate 10 having a curved edge is attached, and a sirocco fan 11 is pivotally attached to the motor 8 at the lower part of the annular warm air discharge plate 10 so that the heater case 6 can be rotated. A heater installation plate 12 is provided in the lower part, and a halogen heater 13 is attached to the heater installation plate 12.

    Further, in the embodiment shown in FIGS. 3 to 4, heat is immediately released from the halogen heater 13, and the increased heat is concentrated on the annular hot air discharge plate 10, and the warm air of the annular hot air discharge plate 10 is directed downward. The sirocco fan 11 allows the warm air to be discharged into the futon with an annular discharge widely around.

    Further, in the embodiment shown in FIG. 5, the halogen heater 11 may have an arbitrary shape.

    Moreover, a quartz tube or a carbon heater can also be used as a heater and may be made into arbitrary shapes.

    Then, an abnormal heating safety device is provided in the halogen heater 13, the motor 8, and the annular hot air discharge plate 10, and the device is activated and automatically stopped when abnormal.
