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 study desk with a chair rest facing the desk.

Conventional foot warmers generally form a closed flat container with a flat plate on the top surface, a heating element is installed inside the container to warm the plate, and the heating element is energized. The toige method is used, in which the plate is warmed by doing this, and the feet are warmed by placing the feet on the plate.

Therefore, 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 warmed, and the lower limbs or knees benefit from the foot warmer, but only the tip of the foot is heated. Only the affected area gets 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 a long time to warm up at the beginning of use.

There are also pants-shaped foot warmers that are bag-shaped and can be covered up to the waist, but these have the disadvantage of restricting the freedom of the feet.

Taking these points into consideration, the present invention is able to warm not only the toes but also the lower limbs and knees, and also shortens the time it takes to warm up at the beginning of use, allowing you to enjoy the freedom of your feet. The purpose of the present invention is to provide an efficient foot warmer that uses hot air more effectively.

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

Reference numeral 1 in the figure denotes a foot warmer main body consisting of a flat, closed, square-shaped container, and a front end edge of the foot warmer main body 1 extends along the front end edge and communicates with the inside of the container. Blow room 1
a is a protruding shape.

A blower fan 3 driven by a motor 2 is disposed in the blower chamber 1a, and a plurality of air intakes are provided on the rear side of the blower chamber 1a facing the rear edge of the foot warmer main body 1. A mouth 4 is provided.

On the other hand, the foot warmer main body includes a top plate 5 made of a flat plate;
It has a flat shape formed from the base 6 and the side plate part,
The main body and the ventilation chamber 1a are joined at the lower end of the ventilation chamber 1a, and a heating element 7 is mounted near the joint.

Further, a plurality of first discharge ports 8 are provided at the rear end edge of the top plate 5 for directing the hot air toward the ventilation chamber 1a at a predetermined angle of elevation, and further near the end thereof. A plurality of second discharge ports 9 are provided to discharge hot air directly upward.

That is, a portion of the warm air flowing through the hot air passage formed between the upper surface plate 5 and the base 6 is reversed below the first discharge port 8, and the hot air is transferred to the first discharge port 8.
A rectifying plate 10 having a guide surface 10a that guides and discharges air from the air at a predetermined angle toward the air blowing chamber is mounted.

Both the first outlet 8 and the second outlet 9 are formed by a large number of small holes to increase the static pressure in the hot air passage.

On the other hand, a plurality of legs 11 are provided on the lower surface of the base to prevent slipping when the foot warmer is placed on the floor during use.

In a foot warmer with such a configuration, 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, and the air is heated by the heating element 7. It becomes warm air, and the top plate 5 and base 6
The hot air passes through the hot air passage formed by the gap and flows backward in the direction of arrow a while warming the top plate 5.

By the way, a part of the hot air flowing through the hot air passage is passed through the rectifier plate 1.
0, and is discharged from the first discharge port 8 toward the ventilation chamber 1a at a predetermined angle corresponding to the inclination angle of the rear end guide surface 10a of the fluid regulator 10 (arrow b1),
Thereafter, as shown by arrow C, a corresponding amount is sucked into the foot warmer body again through the intake port 4.

Therefore, when you put your foot on the top plate 5, 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, warms the tip of your foot. The warm air discharged from the discharge port 8 also warms the lower limbs or knees of the human body.

On the other hand, the remainder of the hot air that has passed through the hot air passage is sent to the second outlet 9.
It is discharged almost directly upward as shown by arrow b2, and serves to warm the lower metal body of the desk.

In the above embodiment, the rear end guide surface 1 of the current plate 10 is
Although the explanation has been made assuming that the angle of 0a is fixed, the discharge angle of hot air can also be adjusted by making the angle adjustable.

Since the present invention is configured as described above, it is possible to heat not only the feet placed on the top plate of the foot warmer but also the knees, etc. Moreover, since it is a hot air circulation type, the warm air can be used effectively. The structure allows you to move freely without worrying about the freedom of your feet.

Furthermore, since the top plate has two types of discharge ports, one that discharges hot air diagonally forward and one that discharges hot air directly above, depending on the hot air discharged from the latter outlet, It has the advantage of being able to heat the entire area below the desk.
