Description

[Detailed description of the invention] This invention is a chair rack that is used to warm the human body's feet by placing it under the desk at a study desk, etc., while sitting on a chair facing the desk. Concerning vessels.

FIG. 1 is a perspective view of the foot warmer, and FIG. 2 is a sectional view thereof.

The foot warmer main body 1 consists of a flat closed container,
A ventilation chamber 1a is formed protruding from its front edge and extends along the front edge and communicates with the interior of the container.

An intake port 2 is provided on the upper surface of the ventilation chamber 1a, extending along the ventilation chamber 1a, and having a wire mesh or the like arranged at the opening.
A ventilation fan 3 and a fan motor 4 are installed in the ventilation chamber 1a.
is installed.

On the other hand, the foot warmer main body 1 includes a top plate consisting of a flat panel 5;
The main body 1 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, at the other end of the panel 5 opposite to one end where the ventilation chamber 1a is disposed, a plurality of discharge portions 8 facing diagonally upward and forward for discharging warm air are arranged along the edge of the panel 5. The panel 5 has a predetermined inclination toward the discharge section 8 with the apex at the junction with the ventilation chamber 1a.

A warm air tunnel is formed by this panel 5, base 6, and side plate portion.

However, in the foot warmer having such a configuration, by energizing the fan motor 4 and the heating element 7, the fan 3
Air is sucked in from the intake port 2, and the air is heated by the heating element 7 and becomes warm air, which blows the panel 5 and base 6.
It passes through the wind tunnel formed by the side plate portion and the side plate portion, and heads toward the discharge portion 8 in the direction of arrow a shown in FIG. 2 while warming the panel 5.

The hot air discharged from the discharge port 8 as shown by the arrow d functions as a heater when it hits the lower limbs or knees of the human body, and by giving the discharge port 8 a predetermined angle of elevation, the hot air is heated as shown by the arrow d. As such, a considerable amount of the air is sucked into the intake port 2 again.

In this case, the radiant heat (arrow C) radiated from the heated panel 5 also warms the tip of the foot placed on the panel 5.

However, when the foot warmer is used as described above, as shown by arrow e in Fig. 3, the cold air on the surrounding floor will be drawn in, resulting in a decrease in the temperature of the warm air indicated by the arrow, a decrease in the surface temperature of the panel 5, and a decrease in the surface temperature of the panel 5. There are disadvantages such as sensory disadvantages due to cold air.

In view of these points, it is an object of the present invention to provide a hot air foot warmer that can prevent cold air from being drawn in from the surrounding floor, and that can also prevent a drop in panel temperature.

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

FIG. 4 is a perspective view of the foot warmer of the present invention, and FIG. 5 is a sectional view of the same, and the same parts as in FIGS. 1 to 3 are designated by the same reference numerals and their explanations will be omitted.

4 and 5, as shown in the figures, in addition to the conventional outlet 8, the other three ends of the foot warmer main body 1, excluding one end where the ventilation chamber 1a is provided, are provided. A plurality of peripheral discharge ports 9a, 9b, and 9C each discharge directly upward.
1 or among the above three ends, excluding the terminal in which the conventional discharge port 8 is provided, peripheral discharge ports 9a and 9C that discharge directly upward are provided along the edge of at least two of the ends. .

As a result, the hot air discharged from the peripheral discharge ports 9a, 9b, and 9C flows upward, as shown by the dotted arrows in FIG. 4, and the air curtain prevents cold air from entering from the floor. This function allows comfortable heating without affecting the hot air discharged from the conventional discharge port 8.

As explained above, in the present invention, in addition to the conventional outlet, a plurality of outlets are installed at each end of the foot warmer body, excluding the end where the ventilation chamber is provided, each of which discharges directly upward. By arranging the peripheral discharge part along the edge, the warm air discharged from the peripheral discharge port flows upward, and functions as an air curtain to prevent cold air from entering from the surrounding floor. It is possible to provide a foot warmer that prevents cold air from being drawn in from the floor of the floor and further suppresses a drop in the temperature of the panel surface.
