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).
The feet and legs were warmed by passing through the heating element of C and converting it into hot air, which was then introduced into the foot warming table and a warm tare bag made of breathable mesh cloth such as nylon or polyester. .

However, conventional foot warming tables have the following drawbacks.

(1) Since there are no ventilation holes on the top of the foot warming table, all hot 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) ) Warm air is not blown onto the top surface of the foot warming table, so if the foot warming table is large, temperature unevenness is likely to occur.

(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 made to solve the above-mentioned problem, and by providing a ventilation hole through which hot air blows out on the footrest surface of the footwarming table and an air volume adjustment body that adjusts the ventilation hole, the footwarming table can be used independently. To provide a heating device that enables the use of the heating device and provides uniform heating temperature so that the soles of the feet do not become stuffy.

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 warm air heated by the heating element 3, 5 is a foot warmer that is heated by the warm air 4, 6 is a mesh made of nylon, polyester, etc. that has ventilation holes that are heated by the warm air 4. It is a warm air bag made of cloth.

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

A ventilation hole 8 is provided in the footrest 7 of the foot warming table 5, and a part of the warm air 4 is blown out to the footrest surface.

Reference numeral 11 denotes a hot air outlet provided in the foot warmer table, and a hot air bag 6 having ventilation is attached to this outlet, and a hot air outlet 11 is opened in a part of the foot warmer table so that hot air is introduced into the hot air bag. There is.

Reference numeral 12 denotes an adjustment body having a ventilation hole 13 of the same size as the ventilation hole 8 opening in the footrest surface of the foot warming table, and is attached to the back surface of the footrest surface so as to be able to freely adjust the air volume. The body 12 is a hot air outlet 11 which is a supply port to the hot air bag 6.
When the population part 14 is closed, the ventilation holes 8 on the footrest surface and the ventilation holes 13 on the adjustment body 12 are fully open and coincide with each other, and the warm air does not go to the hot tare bag 6, but all the warm air flows to the feet of the foot warming table. It is released from the ventilation holes 8 on the mounting surface.

On the other hand, as shown in FIG.
When the ventilation hole 13 of No. 2 is fully closed and does not match, all hot air is supplied to the hot tare bag 6, and no hot air is released to the footrest surface. The air volume can be adjusted as needed between the two.

The configuration described above provides the following effects.

When it is not desired to supply hot air to the hot air bag 6, the air vent 13 of the regulator 12 is aligned with the air hole 8 on the footrest surface of the foot warming table 5, and the air outlet 11 of the regulating body 12 is fully opened. Since the regulator 12 closes the inlet 14 of the blower 1
The warm air rotated and heated through the heating element 3 passes through the ventilation hole 13.8 of the foot warming table 5, and all of the warm air is discharged from the footrest surface to collect heat.

Next, when you want to supply warm air to the hot air bag 6, move the movable adjustment body 12 and use the ventilation hole 13 and the ventilation hole 8 on the footrest surface.
By fully closing the hot air bag 6, the air outlet 14 of the hot air outlet 11 of the other hot air bag 6 becomes open, so all the hot air generated after passing through the heating element 3 is supplied to the hot air bag 6. and contributes to heat collection.

It goes without saying that by appropriately adjusting the movable range of the adjusting body 12 within the fully open and fully closed ranges, warm air can be released from the hot air bag 6 and the footrest surface of the foot warming table 5 at the same time.

As mentioned above, by heating the upper legs with a hot air bag, providing ventilation holes on the footrest surface of the foot warming table, and providing an air volume adjustment body between the hot air bag and the foot warming surface of the foot warming table, The structure allows the soles of the feet to be heated with an appropriate amount of warm air, so it can be used as a standalone foot warmer.The footrest surface is heated evenly, and even when the soles of the feet are far from the footrest surface, the soles of the feet are warm and do not get stuffy. It can be a device.
