JPS58175749A - Hot-water heater by making use of remaining heat of flue gas - Google Patents

Abstract

PURPOSE:To prevent freezing from occurring by making a circulating pump unnecessary, by connecting a heat absorbing tube inside a flue gas cylinder and a heat radiating tube inside a hot water tank at their respective spaces between their upper end parts and between their lower end parts by connecting tubes provided with opening parts in an inverted shape of the letter T on their tops with each other. CONSTITUTION:A spiral shape heat absorbing tube 6 inside an upright flue gas cylinder 2 of a stove 1 and an upright spiral shape heat radiating tube 7 inside a hot water tank 3 are connected at their respective spaces between their upper end parts and between their lower end parts by a high temperature connecting tube 8 and a low temperature connecting tube 9 with each other. Tubes 10 and 11 in an inverted shape of the letter T are provided on the top parts of these connecting tubes 8 and 9, which are opened for the purpose of ventilation, release of steam and injection of antifreeze.

Description

[Detailed description of the invention] Boiling water using residual heat from exhaust smoke from stoves, etc.! + installation has been devised, but in those cases, a circulation pump is installed between the heat absorption pipe and the hot water storage tank.
11 [Although methods such as increasing the circulation force due to temperature differences are being considered, this method not only requires a large amount of materials and labor, but also requires a long circulation route, so it freezes during the winter night. However, serious accidents occurred frequently, hindering its widespread use.

Misfire 8A#'i The present invention, which aims to eliminate these drawbacks at once, will be described with reference to the embodiment fIIK shown in FIG.

(6) is a hollow heat-absorbing tube that extends vertically upward in a circular K shape along the inner cylinder of the smoke exhaust pipe of the stove (1), and its upper and lower ends are the smoke exhaust pipe. Each has a joint metal fitting (12 adjacent parts) protruding from the side surface. ('7
The heat dissipation pipe (similar to the heat absorption pipe in the phrase) is also an upright type with a spiral fall, and the lower end faces upward in a U-shape and is located above the hot water storage tank.
K is provided with a joint fitting (-) together with the protruding upper end. The upper end of the heat absorption pipe (6) and the heat radiation pipe (η
The lower end portions of the two are connected to each other through a low temperature communication pipe (9) so as to allow free flow. Moreover, each of these communication pipes has an inverted T-shaped pipe provided at the top for the purpose of venting air, releasing steam, and injecting antifreeze. ' When the stove is burned, the temperature of the liquid inside the heat absorption tube (η rises, becomes lighter, flows upward, and radiates heat through the high temperature communication t (8). There is a KflL person inside the tube ω.The heat dissipation pipe (7) is cooled by the water pressure, so the liquid inside radiates heat and increases its specific gravity, increasing the specific gravity of the heat dissipation tube. As long as the heat absorption pipe inside the smoke exhaust pipe is heated, the water reaches the hot water tank (3) and repeats this movement to heat the water in the hot water storage tank (3).As described above, the present invention is an extremely simple device, but the circulation pump There is no need for this, there is no breakdown due to freezing, and the installation location of the hot water storage tank is no longer necessarily restricted to a high place, so the effects are extremely large.
