Description

[Detailed Description of the Invention] The present invention relates to an electric foot warmer used for heating the feet of a human body, which is placed under a chair-type study desk or the like while sitting facing the desk.

Conventional foot warmers generally take the form of a closed, flat box-shaped container with a flat plate on the top surface, and a heating element for warming the plate is installed inside the container. The method is to heat a plate by energizing it, and then place your feet on top of the plate to keep yourself warm.

Therefore, in the above-mentioned conventional foot warmer, only the sole of the foot in contact with the plate or the vicinity thereof is heated; There are drawbacks such as heating only the area that is exposed to heat.

Furthermore, since the device is warmed only by radiant heat radiated from the plate heated by the heating element, there are also disadvantages such as a time required for the device to warm up at the beginning of use.

In view of the above-mentioned points, this invention can completely heat the toes and also warm the instep or lower limbs, shorten the time it takes to warm up at the beginning of use, and further increase the effectiveness of heating air. The purpose is to provide a foot warmer that is efficient and easy to use.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

Figure 1 is a perspective view showing the external appearance of the foot warmer of the present invention, and Figure 2 is a
It is a sectional view of the above-mentioned foot warmer.

In the figure, reference numeral 1 denotes a foot warmer main body consisting of a flat closed box-like container, and the front end thereof has a ventilation chamber 1a extending along the front end edge and communicating with the inside of the container. A blower fan 3 driven by a motor 2 is disposed in the blower chamber 1a, and the blower fan 3 is disposed in the blower chamber 1a.
A plurality of air intake ports 4 are provided on the side surface facing the rear end edge of the foot bath body of a.

On the other hand, a heating element 7 is located near the joint between the flat box-shaped foot warmer main body 1 formed from the top plate 5, the base 6, and the side plate, and the lower end of the ventilation chamber 1a. The foot warmer body 1 is provided with a discharge port 8 on the upper surface of the rear edge thereof for discharging warm air diagonally forward.

In addition, the reference numeral 9 in the figure indicates the breathability laid on the top plate 5;
The heat conductive mat 10 has legs that serve to prevent slipping on the floor when the foot warmer is in use.

By the way, the foot warmer main body 1 is fitted with a cover 11 that extends from the top of the ventilation chamber 1a to the upper half of the foot warmer main body 1 and covers the tip of the foot placed on the foot warmer main body 1. There is.

When the fan motor 2 and heating element 7 are energized, air is sucked in from the intake port 4 by the blower fan 3.
The air is heated by the heating element 7 to become hot air, passes through the hot air passage formed between the top plate 5 and the base 6, flows backward as shown by arrow a while warming the top plate 5, and is discharged from the discharge port. As shown by the arrow b, the air is discharged into the ventilation chamber 1a at a predetermined angle, and then, as shown by the arrow C, a considerable amount of the air is sucked into the foot warmer main body 1 from the air intake port 4 again.

Therefore, when you place your feet on the top plate 5, the soles of your feet are warmed by the radiant heat (arrow d) radiated from the top plate 5, which is directly heated by the hot air flowing through the hot air passage. The warm air discharged from the outlet 8 warms the lower limbs or knees of the human body.

By the way, since a cover 11 that covers the toes is attached to the front half of the foot warmer main body 1, the warm air discharged from the outlet 8 flows into the cover 11, and then passes through the inlet. Warm air is drawn into the foot warmer main body from 4, and the warm air is always stored inside the cover, and the temperature inside the cover is always maintained at a constant level, thereby preventing the toes from feeling cold.

As explained above, in the present invention, it is possible to heat not only the feet placed on the top plate of the foot warmer body, but also the knees, etc. Warm air is always accumulated inside the cover, which can reliably prevent the toe area from getting cold.

In addition, the above cover also serves as a guide for hot air to the intake port, and the hot air discharged from the discharge port is effectively guided to the intake port, so heating efficiency can be improved and use can be started. This has effects such as being able to shorten the rise time at the same time.
