Description

[Detailed Description of the Invention] The invention relates to a warm air type electric kotatsu whose heater unit is much thinner than conventional ones.

An example of such a thin heater unit is shown in Japanese Patent Application Laid-Open No. 59-66653. As shown in FIG. 3, the air generated by the fan 1 flows as shown by the solid arrow, contacts the heater 2, and is supplied as warm air. 1 is located outside the reflector 3, and the heater 2 is also located outside the reflector 3 at a distance from the reflector, so cold air is supplied in the direction perpendicular to the plane of the paper where there is no heater, and hot air is blown out. Spotty and uncomfortable.

This proposal was devised in view of the above points.According to this proposal, a fan is installed in a room consisting of a component mounting section and a cover provided opposite to this component mounting section, and a heater is attached to the component mounting section. The heat generated by the heater is trapped in the chamber, and the heat can be evenly blown out from the outlet provided in the component mounting portion by rotation of the fan.

An embodiment shown in the drawings will be described below. 1
Reference numeral 1 denotes a substantially rectangular, dish-shaped component attachment part that is fixed to the wooden frame parts A and B of the kotatsu body with screws C and D. A recess 12 is provided in the center of the flat part P of the component mounting portion, and a motor 13 is fixed through the recess 12. Hollow holes 14 and 15 are provided parallel to each other on both sides of the motor 13, and heaters 16 and 17 are mounted facing these holes. A control section 18 is provided on one side of the component mounting section 11, and is used for blinking, switching, etc. of the heater.
The peripheral edge portions of the component mounting portion on three sides other than the control portion mounting side are inclined upward, and each sloped portion 11a is provided with a plurality of half-cut and raised portions 19, 20, and 21.

A fan 22 rotated by a motor 13 is provided above the component mounting section 11. Parts mounting part 1
Further above the cover 1, a cover 23 is provided which is attached to the component mounting section and whose peripheral edge abuts the upper inclined peripheral edge of the component mounting section. The peripheral edge of this cover forms a downwardly inclined surface 23a. Therefore, the fan 22 is located within the chamber 24 formed by the component mounting portion 11 and the cover 23. In this chamber 24, the temperature rises due to the heat generated by the heater, and the air becomes lighter and accumulates through the spaces 14 and 15. 25 is a protective guard.

Next, we will discuss its effect.

When the heaters 16 and 17 are turned on, the air whose temperature has increased and become lighter due to the heat generated by the heaters accumulates in the chamber 24 constituted by the cover 23 and the component mounting portion 11 and the fan 22 Due to the rotation of the kotatsu, the air outside the kotatsu is sucked in from the spaces 14 and 15, and the air inside the chamber 24, whose temperature has uniformly increased, is brought to the half-cut and raised portion 1 provided in the component mounting portion 11.
The user is provided with hot air that is uniformly blown out in the radial direction through the blowing portion formed by 9, 20, and 21. At this time, the inclined surface 2 of the cover 23
Since 3a faces downward, it can assist in blowing out the wind.

As described above, according to the present invention, it is possible to always supply even hot air with simple improvements, which is extremely comfortable.
