(Prior art) A foot heater is placed under a desk or the like, and is mainly used for heating a foot. However, as a foot heater of this type, conventionally, a floor heater mat is used. There have been used ones in which the feet are placed on the floor and the feet are warmed by the heat transmitted from the feet, and those in which a warm air heater is placed under a desk or the like and heated by warm air.

(Problems to be Solved by the Invention) However, in a floor heater mat such as the above-described floor heater mat, in which the foot is warmed by heat conduction, only the portion directly in contact with the heating surface is warm and the feeling of heating is insufficient. There were challenges. Also, put the warm air heater under the desk,
When heating with hot air, only the part where the hot air directly hits the feet is heated, but the part where the wind does not hit is cold, and too much hot air may cause discomfort on the contrary. there were.

The present invention has been made in order to solve such a problem, and an object of the present invention is to heat a foot by heat transmitted from a footrest portion and to gently warm the foot by warm air blown out from an outlet. It is an object of the present invention to provide a foot warmer capable of warming the entire foot by wrapping the foot.

(Means for Solving the Problems) In order to achieve the above object, the present invention relates to a panel-shaped foot warmer having a footrest portion and having a fan and a heater incorporated therein, wherein: An outlet for warm air is provided at the rear of the foot, and the outlet and the fan accommodating portion communicate with each other through a plurality of ventilation paths, and the upper surface of the ventilation path forms the footrest portion, Characterized in that a heater wire is attached to the inside of the footrest, further provided with a hot air outlet behind the foot of the footrest,
The outlet and the fan storage section communicate with each other through a plurality of ventilation paths,
The upper surface of the ventilation path forms the footrest, and a warm air outlet is also provided in front of the foot of the footrest.

According to the present invention having the above-described configuration, according to the present invention, the cool air sucked by the fan is warmed by the warm air heater, and the warm air passes through the ventilation path to warm the footrest portion. Since the air is blown upward from the rear outlet, there is an advantage that the warm air from the outlet gently wraps the foot and warms the entire foot.

In this case, the temperature of the warm air gradually decreases as it goes to the outlet, so that the temperature of the footrest decreases as it approaches the outlet.However, the heater wire attached inside the footrest reduces the temperature of the warm air. Can be prevented.

In addition, by providing two outlets for warm air at the front and rear of the feet, the toes of the feet are warmed, and the temperature of the footrest itself is quickly raised by the warm air blown from the front of the feet. Becomes possible.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an external view of a foot warmer according to the present invention, and FIG. 2 is an exploded perspective view thereof.

The foot warmer 1 includes a base 2, a surface material 4 that is placed on the front side of the base 2 to form a footrest portion, a frame 3 that is mounted over the base 2 and the surface material 4, and is built-in. Fan 5 and a heater (warm air heater) 6a.

Here, in the present invention, an outlet for warm air is provided behind the foot of the foot rest (4), and the outlet and the fan storage portion communicate with each other through a plurality of ventilation paths. A footrest (4) is formed, and a heater wire 6b is attached inside the footrest (4).

That is, in the present embodiment, a warm air outlet 7 is provided behind the foot of the foot rest (4), and a plurality of ribs (partitions) 8 are provided upright on the base 2. The surface material 4 is placed on top of ribs (partitions) 8, and a plurality of ribs (partitions) 8, the surface material 4, and the bottom surface of the base 2 communicate with the outlet 7 and the storage portion of the fan 5. A ventilation path 9 is formed.

In the part of the base 2 where the ribs (partition walls) 8 are not provided, electrical parts such as a fan 5, a heater (hot air heater) 6a and a switch 10a are provided. 2 is provided on the bottom surface or side surface.

The surface material 4 is formed by bonding a cloth or the like to an iron plate,
As shown in FIGS. 3 to 5, a heater wire 6b wired in a meandering shape is adhered to the inner surface of the surface material 4.

At the time of mounting, the surface material 4 is put on the front side of the base 2 and the frame 3 and the switch button 10 are further mounted.

As described above, the wind is sucked from the outside by the fan 5, and the wind is sent to the heater (hot air heater) 6a where heat is exchanged to generate hot air. The hot air is sent into each ventilation path 9 substantially uniformly. The warm air sent to the ventilation passage 9 is discharged from the outlet 7 to the outside while heating the surface material 4. At this time, the temperature of the hot air gradually decreases toward the outlet 7, so that the temperature of the surface material 4 becomes lower as the temperature is closer to the outlet 7. In order to improve this, the heater wire 6b is arranged in a meandering manner on the iron plate of the surface material 4 so as to prevent the temperature from being lowered by the heat.

It is more effective to arrange the heater wire 6b at a portion near the outlet 7 for the above-described reason. Also, the heater wire 6b is positioned between the ribs (partitions) 8, and the folded portion is provided at the ribs (partitions). If the notch 8 is provided, the heater wire 6 b will not be caught between the surface material 4 and the rib 8.

(T1.TF1 in the figure) is also provided in the hot air heater 6b (T2, TF2 in FIG. 6). When the surface temperature increases, the thermostat operates to turn off the hot air heater 6a (the fan is driven). Lower. When the hot air heater 6a itself is heated, the thermostat of T2 operates to shut off the power. The thermal fuses TF1 and TF2 operate when the thermostats T1 and T2 stop operating due to a failure. The air volume is switched by a light emitting diode (LED) so that it can be seen. Since the hot air heater 6a is a PTC heater, the temperature does not rise above a certain temperature and the danger of heating is low. .

It should be noted that the drive voltage of the fan is not 100V AC, for example, DC
When using 12V, the heater wire 6b and fan 5
Are connected in series, so that one heater
What is necessary is just to select the resistance of the heater wire 6b so as to obtain a voltage of 2V. Further, when the fan 5 and the air volume are switched between high and low, two heater wires 6b are connected in series (6V + 6
V).

With such a structure, the cool air sucked in by the fan 5 becomes hot air by passing through the hot air heater 6a, warms the surface material 4 when passing through the ventilation path, and raises the hot air from the outlet 7 upward. Blow out.

FIG. 7 shows an example of the use of the foot warmer. As shown in FIG. The warm air gently entangles the feet, creating an environment most suitable for study conditions where the feet are warm and extremely comfortable.

Further, in the present invention, an outlet for warm air is provided behind the foot of the footrest, and the outlet and the fan storage part communicate with each other through a plurality of ventilation paths. And a hot air outlet is also provided in front of the foot of the footrest.
