Description

[Detailed description of the invention] The present invention relates to an electric foot warmer that is used to heat the feet of a human body placed under a chair-mounted study desk, etc., while the person is sitting on a chair facing the desk. .

Conventional foot warmers generally have a closed flat box-like container with a flat plate on the top surface, and a heating element is installed inside the container to warm the plate. A method is adopted in which a plate is heated by applying electricity, and the user places their feet on the plate to stay warm.

However, in the case of the above-mentioned foot warmer, only the part of the foot in contact with the plate, or the very vicinity thereof, is heated, and the lower limbs or knees benefit from the foot warmer. Only parts of it get warm.

In addition, since the device is warmed only by radiant heat radiated from the plate heated by the heating element, there is a problem that it takes time to warm up at the beginning of use.

Additionally, the heat emitted from the foot warmer could have a thermal effect on the floor surface.

In view of the above points, this invention can warm not only the toes but also the lower limbs or knees, shortens the time it takes to warm up at the beginning of use, and makes more effective use of warm air. The purpose is to provide a safe foot warmer that is efficient and does not affect the floor surface with heat.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a sectional view of the foot warmer of the present invention, showing the foot warmer main body 1.
consists of a flat, closed, box-like container, and a ventilation chamber 1a is formed at its front end edge, extending along the front end edge and communicating with the interior of the container.

A plurality of intake ports 2 are provided on the upper surface of the ventilation chamber 1a, and a ventilation fan 3 and a fan motor 4 are disposed within the ventilation chamber 1a.

Further, a guide 5 for guiding the ventilation is installed at the lower end of the ventilation chamber 1a.

On the other hand, the foot warmer main body 1 includes a top plate consisting of a flat plate 6;
It has a box shape formed from a base 7 and a side plate, and the main body and the ventilation chamber 1a are joined at the lower end of the ventilation chamber 1a, and a heating element 8 is attached near the joint. There is.

Further, at the other end of the plate 6 facing the one end where the ventilation chamber 1a is disposed, a plurality of discharge ports 9 facing diagonally upward and forward for discharging hot air are provided. It has a predetermined inclination toward the discharge port 9 with the junction with the chamber 1a as the apex.

Between the plate 6 and the base 7, a middle plate 10 is arranged closer to the base 7, and the plate 6 and the middle plate 10 form a hot air tunnel, and the middle plate 10 and the base 7 form a cold air wind tunnel. It is well-formed.

This cold wind tunnel extends to the same location as the upper air intake port 2 of the air blowing chamber 1a, and an air inlet 11 for sucking air is provided at the bottom of the other end of the container facing the air blowing chamber 1a.

If a floor surface is placed on the bottom surface of the base 7 when using the foot warmer,
It has a plurality of legs 12 that serve as a non-slip member.

Therefore, in the foot warmer having such a structure, when the fan motor 4 and the heating element 8 are energized, air is sucked by the fan 3 from the intake port 2 and the intake port 11, and the air is supplied to the heating element. It is heated by 8 and becomes warm air,
It passes through a wind tunnel formed by the plate 6, the middle plate 10, and the side plates, and heads toward the discharge port 9 as shown by arrow a in FIG. 1 while warming the plate 6.

The hot air discharged from the discharge port 9 in the direction of arrow b acts as a heater by hitting the lower limbs or knees of the human body, and by giving a predetermined elevation angle to the discharge port 9, the hot air is discharged as shown by the arrow d.
As shown in FIG.

In this case, the radiant heat radiated from the heated plate (arrow C) also warms the tip of the foot placed on the plate 6.

In addition, the cold air taken in from the intake port 11 is guided to a wind tunnel formed by the middle plate 10, the base 7, and its extension, preventing the temperature of the base 7 from rising, and directing it to the floor where the foot warmer is placed. Furthermore, while passing through the wind tunnel, radiant heat from the intermediate plate 10 provides a preheating effect.

Figure 2 is a caricature of the foot warmer according to the present invention being placed under a desk, and the arrows in the figure indicate the flow of warm air.

Next, another embodiment of the present invention will be described with reference to the attached FIG.

Note that the same parts as in FIG. 1 are given the same reference numerals and their explanations will be omitted.

FIG. 3 is a sectional view of a foot warmer according to another embodiment of the present invention. In FIG. 1, an air intake port 2 is provided on the upper surface of the ventilation chamber 1a, but in FIG. Instead, all air is taken in through an air inlet 11 provided at the bottom of the other end of the container facing the ventilation chamber 1a.

Moreover, the intermediate plate 10 serves as a guide for ventilation inside the ventilation chamber 1a.

As mentioned above, since air is taken in only through the intake port 11, the radiant heat from the plate 6 and the warm air from the discharge port 9 quickly warm the entire area under the desk, for example, when used under the desk. be able to.

Further, as described above, all the air is taken in through the intake port 11, and while passing through the wind tunnel, it receives a preheating effect by the radiant heat of the intermediate plate 10.

As explained above, in this invention, a motor fan is installed in the foot warmer, air is sucked in from the intake port, the air is warmed by a heating element, and turned into hot air. The heating body heats the toes placed on the plate, and the warm body discharged from the outlet can perform the heating function by hitting the lower limbs or knees of the human body.

That is, since the heating method uses radiant heat from the plate and hot air from the discharge port, it is possible to heat the human body from the toes to the knees.

Moreover, in this invention, the bottom of the foot warmer body has a double-walled structure, and the gap between the double walls is used as an air intake passage that spans the entire length of the foot warmer, which prevents the temperature of the base from rising. It is possible to reliably prevent the effects of heat on the floor surface, etc. on which the product is placed, and the heat that previously escaped to the floor surface can be used to warm the intake air, resulting in economical operation. play.
