SOLUTION: A kotatsu body 3 in which a futon 2 is put on a yagura 1, and an inner end opening 4 is opened in the kotatsu body 3 and an outer end opening 5 is usable so as to face a hot air outlet of a fan heater 6. And a tubular hot air intake section provided as the above.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a warm air kotatsu having a fan heater as a heat source.

[0002]

[Prior art]

 The commonly used kotatsu uses electric heaters, charcoal, bean charcoal, briquettes, etc. as heat sources.

The kotatsu described in the above-mentioned prior art has the disadvantage that cold air enters inside when a person goes in or out and the temperature drops, and the operation of adjusting the strength of an electric heater or charcoal, bean charcoal, or briquette It is troublesome that replenishment work etc. is required, and there is a fear of fire and overheating, carbon monoxide poisoning, and it is economically unfavorable because the cost of purchasing electricity, charcoal, etc. increases. Had a point.

[0004]

[Problems to be solved by the device]

 It is an object of the present invention to provide a novel hot air kotatsu that is extremely preferable for use in a home where a fan heater is owned.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a warm air kotatsu according to the present invention comprises a kotatsu body 3 in which a futon 2 is put on a yagura 1, an inner end opening 4 is opened in the kotatsu body 3, and an outer end opening 5 is provided in a fan heater. No. 6 of the present invention is provided with a tubular hot air intake section provided in a state ready for use, and the tubular hot air intake section is provided with a hot air backflow prevention section. In addition, the wind direction changing portion is provided in the tubular warm air intake portion.

[0006]

[Action]

 The warm air from the fan heater 6 enters from the outer end opening 5 of the tubular warm air intake part and is blown into the kotatsu body 3 through the same part 7 and the inner end opening 4.

[0007]

[Effect of device]

 The hot air kotatsu according to the present invention is used in a home owning a fan heater such as an oil fan heater, a gas fan heater, and an electric fan heater, that is, a part of the hot air blown from the fan heater. Since it is used as a heat source, it is economically advantageous compared to the conventional kotatsu that directly requires the above-mentioned electricity bill and purchase costs such as charcoal. Also, since the inside pressure of the kotatsu body 3 is always higher than the outside air due to the blowing of warm air, when a person enters or leaves, cold air does not enter from outside (small amount). Therefore, there is an advantage that the inside of the kotatsu body 3 does not get cold, and the warm air that is blown into the kotatsu body 3 is discharged from under the rim of the futon 2. To shoulder In addition, it is possible to eliminate the fear of fire and carbon monoxide poisoning, and it requires complicated operations such as adjusting the strength of the electric heater and supplying charcoal, bean charcoal, and briquettes. Not having the effect of convenience, completely avoiding accidents such as forgetting to turn off electricity and overheating accidents such as charcoal, etc. Furthermore, since the warm air kotatsu according to claim 2 has a backflow prevention unit for warm air, it is possible to prevent functional deterioration due to backflow. There is no need to worry, and since the warm air kotatsu according to claim 3 has the wind direction changing portion, it is possible to warm the feet with the warm air downward, which is particularly advantageous in the case of excavated goat.

【Example】

 In the first embodiment shown in FIGS. 1 to 4, a yagura 1 is constructed, a futon 2 is put on the yagura 1 to obtain a kotatsu body 3, and at the same time, under the hem of the futon 2 of the kotatsu body 3, a tubular-shaped warmth is provided. The air intake member 7 has the inner end opening 4 of the warm air intake member 7 opened into the kotatsu body 3 and the outer end opening 5 directed toward the hot air outlet (not shown) of the oil fan heater 6. The hot air intake member 7 is provided with a warm air backflow prevention member 9 which is provided in a state in which the hot air intake member 7 can be used, and which is slidable around the shaft 8 in a portion near the inner end of the hot air intake member 7. In the inner end portion, a wind direction changing member 11 composed of a large number of sheets which can be arbitrarily swung around the shaft 10 is attached.

Further, the second embodiment shown in FIG. 5 is implemented by the dug slag 12.

The present invention may be implemented as follows. That is, the hot air intake member can be attached / detached and folded. The hot air intake member has a two-pronged structure or a three-pronged structure. Make the tower available as a table. As in the conventional example, a heat source such as an electric heater may be additionally provided.
