Description

[Detailed Description of the Invention] The present invention relates to a sunken kotatsu, in which a turret-shaped heater housing is installed in the center of the inner bottom of the sunken kotatsu tub, and more particularly to the structure of the heater housing for a sunkotatsu.

Generally, this kind of horigotatsu has a heater housed in a recess in the center of the bottom of the horigotatsu tank, and the opening of the recess is covered with grates, so the infrared heater is efficient and comfortable and good for health. It has the disadvantage that it cannot be used often, and since the radiant heat from the heater intensively heats the inside of the recess provided in the center of the bottom of the hokotatsu tank, there is a temperature gradient in the center of the bottom of the hokotatsu tank with the outside of the tank. This has the drawback that the larger the amount of heat, the more heat is conducted through the bottom wall of the kotatsu tank and released to the outside of the kotatsu tank, resulting in poor efficiency.

The present invention eliminates these drawbacks and provides a kotatsu that allows the radiant heat from the heater to be effectively distributed within the kotatsu tank.

Hereinafter, a specific embodiment of the present invention will be described in detail based on the accompanying drawings. In FIG. A lattice-shaped top plate 3 is provided at the upper end of 2, a reflector A4 is supported by a concave mirror on the lower side of the top plate 3 with the reflective surface facing downward, and a heater 5 is provided below the reflector A4. Furthermore, a reflecting plate B6, which is formed by a convex mirror, is disposed below the heater 5 so as to face upward.

In the figure, 7 is a turret, 8 is a stile, and 9 is a locking piece protruding from the inner surface of the stile.When the horigotatsu is used, the turret 7 is placed on the locking piece 9, and when not in use, the turret 7 is can be stored in the kotatsu tank 1.

Furthermore, since the top plate of the heater housing is in the form of a lattice, placing your feet on the top plate will efficiently warm your toes, thereby saving energy.

As mentioned above, in this invention, a turret-shaped heater housing containing one heater is installed in the center of the inner bottom of a kotatsu tank with an open top that is buried under the floor. A reflector A made of a concave mirror is placed above the heater, with its reflective surface facing downward, and a reflector B, made of a convex mirror, is placed below the heater with its reflective surface facing upward. The upward radiant heat from the heater is reflected downward by the reflector A, and the reflected radiant heat and the radiant heat directly radiated from the heater radiate to every corner of the lower part of the inside of the kotatsu tank. The downward radiant heat is reflected upward by the reflector B, and the reflected radiant heat and the radiant heat directly radiated from the heater are radiated to the top and upper corners of the kotatsu tank, and one heater The heat is reflected or transmitted evenly throughout the inside of the hokotatsu tank, and therefore, the radiant heat from the infrared heater, which is comfortable and healthy, is reflected to the corners of the hokotatsu tank. The heat is distributed throughout the area, heating the entire hokotatsu tank rather than just a part of it, and the hokotatsu tank is heated efficiently within a short time after startup.Moreover, the heat distribution is even, and the hokotatsu tank is warmed up. This has the advantage that the amount of heat released from the bottom to the outside of the tank is reduced.
