Abstract

PURPOSE: To efficiently heat in a room by holding high vacuum in a pipe, and sealing operating liquid to be evaporated by heating by a heater and condensed at the upper part in the pipe. CONSTITUTION: A pipe 6 is held in high vacuum, and sealed in a bottom with an operating liquid 8 to be evaporated by heating by a heater 7 and condensed at an upper lower temperature part in the pipe 6. That is, when the heater 8 is energized, it is heated to evaporate the liquid 8, which is raised to the upper part in the pipe 6 in contact with the pipe 6 near the room temperature or cooled to be condensed in the vicinity to become liquid, which is fed down to the bottom of the pipe 6, again heated by the heater 7 to be evaporated in a cycle, and the cycle is repeated. When the liquid 8 is condensed, heat is radiated to heat the pipe 6, the heat is transferred to a radiating fan 9 to warm the air around a heating element 4 to be raised at its temperature. The low- temperature air is sucked from a suction port 2 to be heated by the element 4 in the cycle to heat in the room.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating appliance which efficiently heats a small-diameter heating element to secure a large heat radiation area.

[0002]

2. Description of the Related Art Conventionally, a heating apparatus using a heating element that generates heat by electric resistance has a drawback that the heat radiation area is small and the heating efficiency is low.

[0003]

The problem to be solved by the present invention is that the conventional heating apparatus has a small heat radiation area and a low heating efficiency.

[0004]

As a means for solving the above problems, the present invention has an elongated heating element arranged substantially horizontally in a case having an air intake hole formed in a lower portion and an air discharge hole formed in an upper portion. The heating element has a small-diameter heating element placed over the entire length on the inner bottom of a large-diameter pipe made of metal, and the inside of the pipe is kept at a high vacuum and is evaporated by heating the heating element. However, the working fluid that condenses in the upper part of the pipe is sealed.

[0005]

The present invention has the above-mentioned structure, and when the heating element generates heat, the working fluid accumulated in the lower part of the pipe evaporates and rises to the upper part in the pipe, and the temperature becomes low due to contact with the atmosphere. When a pipe with a large diameter is condensed and liquefied by flowing into the lower part of the pipe by contacting the pipe or cooling at a low temperature near it, the large-diameter pipe is heated by the heat generated during condensation and the heating element Since it generates heat and the heat dissipation area is large, the air in the case is efficiently heated,
The high temperature air is discharged from the upper discharge hole, and the cool air is sucked from the lower suction hole to efficiently heat the room.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 and 2, reference numeral 1 denotes an elongated box-shaped case having an air intake hole 2 formed in the lower portion and an air discharge hole 3 formed in the upper portion, and three heating elements 4 near the upper portion. Are horizontally arranged by the bracket 5.

The heating element 4, as shown in FIGS. 3 and 4,
A small-diameter heating element 7 that generates heat when energized is inserted through the inner bottom portion of a metal-made closed and elongated pipe 6 having high thermal conductivity.

The inside of the pipe 6 is maintained at a high vacuum, and the working liquid 8 which is evaporated by heating by a heating element 7 such as CFC and helium and is condensed in the low temperature part of the upper part of the pipe 6 is enclosed in the bottom part. Radiating fins 9 are provided on the outer periphery of the pipe 6 at regular intervals.

This embodiment has the above-mentioned structure, and when the heating element 7 is energized, the heat is generated and the working fluid 8 evaporates, and as shown in FIG. The cycle in which the working fluid 8 is contacted or cooled and condensed in the vicinity thereof to become a liquid, flows down to the bottom portion of the pipe 6, is heated again by the heating element 7 and is evaporated is repeated, and the working fluid 8 is condensed. When this is done, heat is generated and the pipe 6 is heated, and the heat is transferred to the heat radiation fins 9, whereby the air around the heating element 4 is warmed and rises,
The interior of the case 1 is heated by repeating the cycle of being discharged from the upper discharge hole 3 and sucking low-temperature air from the lower suction hole 2 to be warmed by the heating element 4.

In addition to the heating element 7 of the heating element 4 which generates heat when energized, as shown in FIG.
It is also possible to use one that radiates heat by flowing 0 or steam.
