Description

[Detailed Description of the Invention] The present invention relates to an improvement in a heating device capable of heating the feet and legs by heating a foot warming table and a hot air bag with hot air.

Conventionally, this type of heating device has been used as a study heater or a warm air kotatsu, and its structure is as follows.

The cold air generated by the blower is transferred to a honeycomb-shaped or harmonica-shaped heating element that has a positive temperature coefficient of resistance (PT).
It heats the feet and legs by passing through the heating element of C and converting it into hot air, and introducing the hot air into the foot warming table and the warm tare bag made of breathable mesh cloth such as nylon or polyester. Ta.

However, conventional foot warming tables have the following drawbacks.

(1) Since there is no ventilation hole on the top surface of the foot warming table, all of the warm air is supplied from the outlet of the foot warming table to the hot air bag, making it impossible to use the foot warming table alone without using the hot air bag.

(2) Since hot air is not blown onto the top surface of the foot warming table, temperature unevenness tends to occur when the foot warming table becomes large.

(3) Since foot warming tables warm the soles of the feet through heat transfer, the soles of the feet tend to get stuffy.

The present invention was developed to solve the above-mentioned problems.By providing a ventilation hole through which warm air blows out on the footrest surface of the foot warming table, it is possible to use the foot warming stand alone, and uniform heating is achieved. To provide a heating device that prevents the soles of the feet from becoming stuffy due to the temperature.

Examples of the present invention will be described below.

FIG. 1 shows an embodiment of the present invention, in which 1 is a blower, 2 is a cold air generated by the blower 1, and 3 is a honeycomb-like shape having a positive temperature coefficient of resistance and through which the cold air 2 can pass. A harmonica-shaped heating element 4 is a hot air heated by the heating element 3, 5 is a foot warming table heated by the hot air 4, and 6 is a mesh cloth made of nylon, polyester, etc. having ventilation holes heated by the hot air 4. It is a warm air bag consisting of.

9 is a damper that adjusts the air volume ratio between the cold air 2 on the heating element 3 side and the cold air 2a on the detour 10 side, and adjusts the temperature of the hot air 4 so that the hot air bag 6 is always in a constant bulging state. It has the function of

Since the footrest surface 7 of the foot warming table 5 is provided with ventilation holes 8, a portion of the warm air 4 is blown out to the footrest surface.

Figure 2 shows the hot air generator and the foot warmer when a hot air bag is not used.The hot air outlet 11 of the foot warmer 5 is blocked with a stopper 12, and all the hot air is directed to the footrest surface 7. Since the air blows out from the provided ventilation holes 8 and heats the soles of the feet, the hot air will keep the feet warm even if they are a little far from the footrest surface, and the soles will not get stuffy due to sweat.

Although the hot air generator and the foot warming table have been described as having an integrated structure, the present invention is not limited to this. A structure connected by a hose may also be used.

Further, the foot warming table may be a parallel panel, and the ventilation holes provided on the footrest surface may be provided with a ventilation adjustment mechanism, or may have a structure in which the ventilation holes open when the feet are placed.

As mentioned above, the upper leg area is heated by the hot air bag, and even if ventilation holes are provided on the foot rest surface of the foot warmer, the soles of the feet can also be heated with warm air, so the foot warmer can be used alone. A heating device can be provided in which the footrest surface is heated uniformly, the soles of the feet are warm even when they are away from the footrest surface, and the soles of the feet do not get stuffy.
