A foot plate 3p having a plurality of through holes 3h is horizontally fixed to the inner wall 1b on the lower end side of the inner chamber 3 of the boiler body 1 and an electric heater H And a conduit Cd for supplying a coolant to the cooler C from an external cooler are arranged side by side together with a cooler C for cooling the boiler and a power line He installed side by side for supplying power to the electrically heated heater H, And is related to the outside of the body 1. [

A metal scrap Sc is wound around the electrothermal heater H and the cooler C to diffuse heat conduction. This metal scrap Sc is not an essential element of the boiler construction.

Is rotatably supported by a bearing (5b) at the center of a support plate (5a) penetrating downward from the center of the upper lid (1c) of the boiler body (1) and fixed to the lower side inner wall (1b) of the inner chamber (3) A vacuum cleaner 5 in which a plurality of large-diameter and small-diameter through holes 5h for inducing a friction to the support shaft 5x are inserted into a plurality of horizontal multi-stages is installed in the inner chamber 3 It is possible to remove the inner chamber 3 and the filter medium f by operating the small plate 5c so as to be pivoted laterally by the handle 5n formed on the upper end of the support shaft 5x passing through the upper lid 1c .

When the boiler is used, the inner chamber 3 of the body 1 is filled with a porous filter material f in the form of a ball through the inlet 1n provided in the lid 1c so that water or air passing through the inner chamber 3 So that it can be filtered.

The boiler (B) is equipped with a temperature sensor pressure sensor, pressure and temperature, and a controller (CB) to control boiler operation.

Hereinafter, the operation of the present invention will be described.

The water filled in the outer chamber 2 flows into the inner chamber 3 through the connection pipe d2 that connects the outer chamber 2 and the inner chamber 3 and is filled.
When the inner chamber 3 is filled with water, the heating temperature and time are set by the controller CB and then power is supplied from the outside through the conductor He of the electric heater H provided in the inner chamber 3, And the heated hot water is supplied to the outside through the outflow pipe (d3).

The water in the inner chamber 3 is more easily heated because the thermal conductivity is expanded by the rolled metal scrap Sc on the electrothermal heater H.

At this time, because the outer chamber 2 is filled with water, the water in the outer chamber 2 is also preheated by the heat released from the inner chamber 3, thereby preventing the loss of heat in the inner chamber 3.

When the water is cooled by the boiler B, the controller CB sets the cooling temperature and the cooling time, and the coolant is supplied to the cooler C from the external cooling device (not shown) through the conduit Cd The water in the inner chamber 3 is cooled by the cooler C and then flows out to the outside through the outflow pipe d3.

As described above, during heating and cooling of water, water can be heated or cooled while being circulated through a circulation system, heated or cooled in a state contained in the inner chamber 3, and then supplied to the outside by a pump not shown in the drawing .

The air is introduced into the inner chamber 3 through the outer chamber 2 and the cooler C through the inlet pipe d1 and the connection pipe d2 in the same manner as described above when the air is heated and cooled by the boiler B, Or the air is cooled or heated according to the data inputted to the controller CB by the operation of the electric heater H and supplied to the outside through the outflow pipe d3. Heating or cooling of the air is mainly applied to air conditioning.

The filter medium f filled in the inner chamber 3 of the boiler B is for additionally filtering the liquid or gas heated or cooled by the boiler and not for the purpose of filtration of liquid or gas. It is preferable that the liquid or gas required is filtered by the exclusive filtration means and then heated and cooled by the boiler (B).

In the case of recovering the waste heat of the boiler, the water containing the heat or the air flows out through the inlet pipe 4n of the coin pipe 4d of the heat exchanger 4 provided in the outer chamber 2 of the moving body 1 The waste heat is recovered by heat exchange with water or air in the outer chamber (2) of the body (1) while slowly flowing into the pipe (4u).

As described above, when water or air is slightly contained in water or air in the process of heating or cooling air, it is filtered by the filter material (f) filled in the inner chamber 3.

In order to clean the inner chamber 3 of the boiler B, the inner chamber 3 of the body 1 is filled with water to be cleaned and the support shaft 5x of the vacuum cleaner 5 is fixed to the support shaft 5x by the handle 5n. So that the plurality of small plates 5a engaged with the small plate 5a are rotated right and left.

This operation causes friction between the through holes 5h punctured in the small plate 5c and the small plate 5c and the inner wall 1b of the inner chamber 3 of the filter medium f and the body 1, Impurities adhering to the inner wall 1b of the inner chamber 3 of the inner shell 3 and the surface of the filter material f are removed and the inner wall 3b of the inner shell 3 of the shell 1 The precipitate settled in the bottom face portion 1d is discharged to the outside through the drain valve 1v together with the washing water and cleaned repeatedly several times to be cleaned, and the filter material can be repeatedly used.

(Application example of the present invention)

An example in which the multifunctional boiler of the present invention is used in a public bath is explained as follows.

That is, when it is necessary to replenish the temperature due to the lowered water temperature during use, instead of operating the large boiler installed in the public bath every time, hot water of the hot water is supplied to the inlet pipe (1) of the boiler (B) the hot water in the inner chamber 3 is filled in the inner chamber 3 via the outer chamber 2 via the outer chamber 2 via the outer chamber 2 and the operation of the electrothermal heater H provided in the receiving plate 3p of the inner chamber 3, The hot water is supplemented by lowering the temperature by heating, and the heated water is returned to the hot water through the outlet pipe (d3).

In addition, when the water is removed from the body contained in the hot water or the foreign matter is filtered by the filter medium (f) while moving through the inner chamber (3) together with water, the filtered hot water is supplied to the hot water.

The waste water is discharged to the outflow pipe 4u through the inflow pipe 4n of the coin pipe 4d of the heat exchanger 4 provided in the outer chamber 2 of the body 1 in order to recover the waste heat of the discharged bath water Heat is exchanged between the water in the outer chamber 2 and the water passing through the coil pipe 4d of the heat exchanger 4 so that the waste heat is recovered in the outer chamber 2 and the water in the outer chamber 2 is recovered by the recovered waste heat, Lt; / RTI > Since the heating energy in the inner chamber 3 is reduced as much as the water in the outer chamber 2 is preheated, the heat utilization rate in the public bath can be further increased.

Therefore, it is possible to maintain the water temperature of the hot water at a constant level with less energy cost compared with the case of supplementing the water temperature of the hot water by the large boiler every time. At the same time, the water of hot water can be filtered without using a separate filtration device, The multifunctional boiler of the present invention can be advantageously used such that the waste heat is recovered from the waste water of the boiler and the energy use is further reduced.
