Conventionally, various types of indoor hot water heating systems have been put to practical use, and FIG. 9 of Conventional Example 1 is a typical hot water circulation heating system listed in Non-Patent Document 1.
That is, in Conventional Example 1 (FIG. 9), a boiler equipped with a pressure gauge, a safety relief valve, and a drain valve is heated with electricity, kerosene, gas, etc., and warm water heated by a hot water boiler is connected to the piping and the outgoing header. The water is sent to each radiator in each living room to heat the room, the hot water is returned from the radiator to the boiler via the piping and the return side header, and reheated. A circulation pump, a sealed expansion tank, an air vent valve, a header, etc. are accommodated, and an air vent valve, a thermostud valve, and a hot water inlet / outlet valve are also arranged in each radiator.

Further, in the hot water circulation heating system, the means shown in FIG.

  The hot water circulation heating system of Conventional Example 1 (FIG. 9) includes a hot water boiler provided with a safety relief valve, a pressure gauge, a drainage gate valve, and a water supply gate valve, a sealed expansion tank provided with a safety relief valve, And a return header, a hot water circulation pump, an air separator with an air vent valve installed between the boiler and the circulation pump, a radiator group with a partition valve for water supply and drainage, and piping connecting each device and valves Since it consists of pipes and is connected to indoor radiators from the boiler room provided in the building by piping under the floor, in the walls, and in the ceiling, there are the following problems.

(I). When the hot water circulation heating system becomes obsolete, rust occurs on the metal panels (radiators) and pipes, hot water does not circulate or water leaks occur, and the floor, walls, and ceiling are soiled. Since repairs are buried piping, recovery requires time and money.
(B). When the circulation pump or the like in the system breaks down, the heating of the entire system is stopped, and when the equipment is repaired or replaced, piping change work such as changing the specifications of the boiler body occurs.
(C). Because of the long piping from the hot water boiler to each radiator, heat loss due to heat dissipation in the piping path is large.
(D). The radiator is equipped with an internal air vent, a maintenance water supply / drainage gate valve, etc., and the thermostat protrudes, which impairs aesthetics.

Since the hot water circulation radiator of Conventional Example 2 (FIG. 10) circulates hot water from the central boiler chamber to each radiator as in Conventional Example 1 (FIG. 9), There are problems (b), (b), (c), and (d).
In addition, since the plastic hot water circulation pipes are arranged in parallel in the lateral direction, the flow resistance of the pipes becomes large, and the circulation pump requires a larger capacity pump than is necessary from the circulation system. .
Also, as shown in FIGS. 10 (B) and 10 (C), when the horizontal pipe group is made into a heat radiating panel continuously with sockets at both ends, there are many fusion points such as a fusion plate, a closing plate, a socket, and a tube group. The production is complicated and there is even a fear of water leakage.
In the fusion of the tube group and the fusion plate, problems such as closing of the open end and fusion flaws, occurrence of unevenness due to the thermal load of the fusion plate, occurrence of unevenness due to fusion of the tube length, etc. Wearing work requires skill.

  Conventional Example 3 (FIG. 11) is an electric heater that has a humidifying function and discharges warm air containing moisture from the outlet, but forced convection heat transfer type heating that employs an electric fan. It stirs room air and winds up dust, has a problem of sound caused by the fan, has an uncomfortable feeling that the fan blows directly on the body, and is suitable for a small space such as a toilet. It cannot be applied to the hot water circulation heating type.

Conventional Example 4 (FIG. 12) is a natural convection heater that circulates hot water supplied from a heat source device in a fin coil of an indoor unit, and drops water branched from a supply-side hot water pipe from above the fin coil. It evaporates on the surface of the fin coil and requires equipment such as an open drain tank, a water level sensor, a strainer, etc., and the dripping and evaporating of water is unsanitary, and the overflow of water in the drain tank There are also problems.
The present invention solves or improves the problems of the conventional examples 1 to 4, and is a hot water circulation type natural convection heating system, in which a heat radiating portion and a route pipe are constituted by plastic pipes, and moisture is released. It provides an epoch-making heating system that is easy to install and maintain, and is capable of mild and sanitary heating.

  As shown in FIG. 1, the present invention is an electric heating type indoor heating system including a plastic resin heat radiating portion 8 and a hot water circulation system SY. The heat radiating portion 8 includes a number of vertical pipes 8B arranged in parallel. The group and the vertical pipe 8B group are communicated by the horizontal pipe 8A at the upper end and the lower end, and the exposed hot water circulation made of all plastic pipes is provided with the hot water supply port 8S and the hot water discharge port 8R in the horizontal pipe 8A at the lower end. The heat-dissipating panels 81 and 82, and the hot water circulation system, the air separation pressure tank 2, the circulation pump 3, the pipe heater 4, the ball valves 6 </ b> A, 6 </ b> B, 6 </ b> C, cheese 7, 7A is connected with a plastic pipe 5A to accommodate the hot water circulation function, and is connected to the heat radiation panels 81 and 82 with the forward pipe S and the return pipe R, and in the return path of the hot water A desorption type electric water circulation heating system interposed humidification tank 12, 12 'provided with a moisture releasing cap 12C on top.

In this case, the meaning of “exposed” of the heat dissipating panels 81 and 82 means that at least the heat dissipating panel surface is not covered.
The new air separation pressure tank 2 functions as an expansion tank and an air separator in the conventional example 1 (FIG. 9), and has a capacity at room temperature of water refluxed in the heating system. However, typically, it is a plastic tank having a capacity of 0.5 L and corresponding to 1 to 3 kw.
Moreover, the circulation pump 3, the pipe heater 4, the ball valves 6A, 6B, 6C, and the cheese 7, 7A constituting the heater unit box 1 can be prepared with conventional products, and the circulation pump 3 can be a metal with a conventional resin electromagnetic pump. A circulating pump may be used, and the pipe heater 4 is an energy-saving, 1kw exothermic SC heater (trade name) manufactured by Thermal Engineering Co., Ltd., which is appropriately used according to the heating capacity, and a plastic pipe 5A for piping. May employ a conventional pipe made of ethylene-propylene rubber (EPDM) having excellent durability, heat resistance and solvent resistance.

  In addition, the heater unit box 1 is packed with the hot water circulation function of the conventional example 1 (FIG. 9) as a package. However, in other words, it is configured so that it can be used both vertically and horizontally, and in a 1 kw to 3 kw heating system, the heater unit box 1 typically has a width L1 of 180 mm, It is a small box with a square tube shape with a depth W1 of 160 mm and a height h1 of 590 mm.

Moreover, the heat dissipating panel is one, the hot water supply port 8S is disposed at one end of the horizontal pipe 8A at the lower end, the hot water discharge port 8R is disposed at the other end, and the front of the hot water discharge port 8R of the horizontal pipe 8A is closed. Only the outermost vertical pipe 8B corresponding to the hot water discharge port 8R may be a descending path from the upper end horizontal pipe 8A, but typically, as shown in FIG. 8, the first heat radiating panel 81 and the second heat radiating panel are used. 82, the hot water supply port 8S is disposed at one end of the lower end horizontal pipe 8A of the first heat radiating panel 81, and the hot water discharge port 8R is disposed at one end of the lower end horizontal pipe 8A of the second heat radiating panel 82.
In addition, a plurality of radiators HR provided with the plastic resin radiator 8 may be arranged corresponding to one hot water circulation system SY. In this case, in the wall, for the conventional forward side piping and return What is necessary is just to arrange | position the cheese joint for side piping, and to connect each heat radiator HR to one warm water circulation system SY.

Accordingly, the present invention is an exposed heat radiating panel in which the heat radiating portion 8 is made of a plastic pipe group, and since the hot water circulates in the heat radiating panel of the plastic pipe group to heat and heat the surrounding air, the heat radiating panels 81 and 82 are provided. A gentle heating gentle to the human body can be obtained by the sum of the mild heating in the room and the indoor heating by the effect of radiant heat from the surfaces of the heat radiation panels 81 and 82.
The heat dissipating panels 81 and 82 become a uniform heating surface by simultaneous inflow from the horizontal pipe 8A to the vertical pipe 8B group. The heating temperature of the heat dissipating panels 81 and 82 is the surface temperature (standard: 60-70 ° C.), so it is safe and secure for the human body.
Moreover, since the humidifying action using the circulating hot water is made possible when heating with the plastic heat radiating panel, the room becomes a heating environment excellent in health and hygiene.

Moreover, since the warm water circulation system SY is a form housed in the heater unit box 1 and is a small factory-made product, it is easy to arrange, construct, and maintain the warm water circulation heating system in a residence.
Further, in the open type system in which the circulating water in the system comes into contact with the outside air, aging occurs due to rust on the path, but in the present invention, the entire hot water circulating heating system including the heat radiating unit 8 is used. Since there is no rust generating material such as a metal pipe in the hot water circulation path, it is possible to apply a simple open-type moisture releasing means with the circulation path being an open type.

In the heating system of the present invention, it is particularly preferable that one radiator HR provided with the plastic resin radiator 8 and one heater unit box 1 are arranged corresponding to 1: 1. .
In this case, for example, even if a failure occurs in one heater unit box 1, the other radiators HR function, so that the malfunction of the heating system in all the rooms of the house can be avoided, and all the heating in the living area is stopped. This situation can be avoided.
And the heater unit box 1 which incorporates a heating part (pipe heater) can be arrange | positioned adjacent to the heat radiator HR, and the heat from the piping in the path | route from a heating part (boiler) to a heat radiator of the prior art example 1 (FIG. 9). There is no heat loss due to dissipation, and even if heat dissipation occurs in the heater unit box 1, the heat dissipation becomes indoor heat dissipation, so that an indoor heating system with virtually no heat loss is obtained.

Further, as shown in FIG. 2, the hot water circulation heat radiation panels 81 and 82 according to the present invention include a group of vertical pipes 8B having a small diameter dB between upper and lower horizontal pipes 8A having a large diameter dA, and each vertical pipe 8B is heated air. It is preferable to fuse and integrate with a minimum gap gB that allows only upward flow.
In this case, the horizontal pipe 8A and the vertical pipe 8B are pipes through which warm water flows smoothly. Typically, the horizontal pipe 8A has an outer diameter of 27 mm (wall thickness 5 mm), and the vertical pipe 8B has an outer diameter of 13 mm (wall thickness). 1.6 mm) and the spacing gB is typically 20 mm.

If 80 ° C. warm water flows through the vertical pipe 8B, the outer air of the vertical pipe 8B is heated to become an upward flow for heating. In this case, if the gap gB is wide, the air is centered between the vertical pipes 8B. A cooling downflow occurs.
In the present invention, “the interval gB that allows only heated air to rise” is a gap that prevents the generation of cooling downflow in the middle of the interval gB. If only the rising air flow can be allowed under a small air flow resistance and the gap gB is 20 mm or less, the fluidity is lowered by the air viscosity resistance of the heated air with the vertical pipe 8B, and the efficiency from the vertical pipe 8B is reduced. Air heating / heating cannot be obtained.

  Therefore, the heat radiating panels 81 and 82 provide a heating surface in which hot water flows from the large-diameter horizontal pipe 8A to the small-diameter vertical pipes 8B all together to suppress temperature spots. Since the surface of the vertical pipe 8B group constituting the main heat radiating surface does not cause the flow of cold air from above between the vertical pipes 8B, and can suppress the viscous stagnation of the heated air between the vertical pipes 8B, As a result, heating of the ambient air as per the design value → a rise effect (heating effect) is obtained. For example, in a PP-R resin (polypropylene. Random. Copolymer resin) pipe with an outer diameter of 13 mm, the convective heat dissipation per 1 m length is 18 0.0kcal / mh ° C, radiation heat release (hot water temperature inflow side: 80 ° C, outflow side: 60 ° C, room temperature 20 ° C) is 7.68 kcal / mh ° C, combined with natural convection heating system, circulating hot water → Plastic resin heat dissipation part 8 → Indoor air heating (+) Radiation panel Heating of radiant heat is obtained as mild heating heat due to room temperature and radiation, and mild heating that feels warmth can be efficiently obtained without raising the room temperature.

  Further, as shown in FIGS. 2 and 8, the hot water circulation heat radiation panels 81 and 82 include a first panel 81 provided with a hot water supply port 8S at one side end of the lower end horizontal pipe 8A and one side end of the lower end horizontal pipe 8A. The second panel 82 having the hot water discharge port 8R is communicated with only the other end of the upper end horizontal pipe 8A, and the facing surface distance gP between the first panel 81 and the second panel 82 is set so as to reduce the amount of cold air from above. It is preferable to integrate at intervals of 28 to 34 mm to prevent intervention flow.

  In this case, as shown in FIG. 8, the first panel 81 and the second panel 82 are integrated by connecting spacer pipes 8D on both sides of the lower horizontal pipe 8A and on the right end of the upper horizontal pipe 8A. The left end of the horizontal pipe 8A is communicated with a communication pipe 8C, the vertical pipe 8B at the left end of the second panel 82 is used as a descending path with the closing plate 8E of the upper horizontal pipe 8A, and the vertical pipe 8B at the right end of the second panel 82 is connected. The descending path may be formed by the closing plate 8E of the lower end horizontal pipe 8A.

  Therefore, as shown in FIG. 8, the hot water path is such that the running water (1) from the hot water supply port 8S at one lower end of the first panel 81 is the lateral water (2) of the lower end horizontal pipe 8A → the vertical pipe 8B of the first panel 81. Upflow water (3) → cross-flow water (4) of the first panel upper end horizontal pipe 8A → cross-flow water via the communication pipe 8C from the upper end horizontal pipe of the first panel 81 to the upper end horizontal pipe 8A of the second panel 82 ( 5) → downflow water in the vertical pipe 8B on the left end of the second panel 82 (6) → crossflow water in the second panel lower end horizontal pipe 8A (7) → upflow water in the vertical pipe 8B on the second panel 82 (8) → second Cross-flow water (9) of the panel upper end horizontal pipe 8A → downflow water (10) of the vertical pipe 8B at the right end of the second panel → Returns to the hot water discharge port 8R at the right end of the second panel 82, the first panel 81 and the second panel The first panel is heated by smooth hot water flow inside 82 The space gP between the first surface and the second panel 82 surface is an interval that allows only the heating up air flow and does not derive the downflow of the cold air, so that the heat radiating section 8 is connected from the horizontal pipe 8A to the vertical pipe 8B group. Combined with the heating effect without temperature spots due to simultaneous inflow, it becomes a smooth natural convection heating surface.

  Further, in the present invention, the heater unit box 1 has a long rectangular tube portion in which a long left side plate 1L and a right side plate 1R are joined, as shown in FIGS. 4 and 5, for example. 1K and an upper lid 1U and a lower lid 1D that are detachably fitted to both ends of the rectangular tube portion 1K, and a left-side plate 1L having an L-shaped cross section has a plurality of upper and lower sides at equal intervals on one side LS1. It is preferable that a plurality of wire insertion holes H1 are provided, and the other side LS2 is provided with a plurality of air circulation holes H3 at positions corresponding to the wire insertion holes H1.

In this case, the left side plate 1L attaches a support material such as a device to the inner surface, and the right side plate 1R plays the role of a lid of the rectangular tube portion 1K.
In addition, the wire insertion hole H1 enables the connection between the electrical wiring box 9A embedded in advance in the wall surface WS or the floor surface FS and the temperature adjustment unit housed in the heater unit box at an appropriate position. It is a size that can be manually inserted, and is typically an oval hole with a width of 60 mm and a height of 40 mm, and is arranged at five locations at intervals of 100 mm.
The air circulation hole H3 dissipates the heat in the heater unit box 1 to the outside, and forms an air through channel in the heater unit box 1, and typically has a width of 20 mm and a height. It is a 40 mm oval hole.
When the heater unit box 1 is used upright, the operation panel 9B is disposed on the upper lid 1U. When the heater unit box 1 is used as a horizontal type, the inclined side 1R of the right side plate 1R that performs the lid function of the rectangular tube portion 1K is used. What is necessary is just to arrange | position the operation panel 9B to '.

Accordingly, by removing the upper lid 1U and the lower lid 1D, the rectangular tube portion 1K can be disassembled into a left side plate 1L and a right side plate 1R having an L-shaped cross section, and the storage device can be fixed only to the left side plate (1L). The heater unit box can be easily maintained by removing the right side plate 1R as the lid member of the portion 1K.
In addition, the heater unit box 1 is also arranged in each room, since the wire insertion holes H1 are arranged in multiple stages in series, so that the connection position with the external electrical wiring box 9A can be selected, and the appearance is not impaired. Can be arranged.
Moreover, since the outside indoor air can flow through the wire insertion hole H1 and the air circulation hole H3 in the heater unit box 1, the heat dissipated in the heater unit box 1 helps the room heating. And an indoor heating system in which heat loss does not substantially occur.

  In addition, as shown in FIG. 4, the heater unit box 1 has a left-side plate 1L having an L-shaped cross section that bends and extends a corner side 1A at both ends, and an end portion of the corner side 1A is an L-shaped anchor piece 1C. The anchor piece 1C of the left side plate 1L and the contact anchor piece 1F for connection are arranged at both ends of the right side plate 1R having the L-shaped cross section. It is preferable to arrange the screw hole H2 and screw the screw hole H2 of the upper lid 1U and the lower lid 1D with the screw hole H2 of the left side plate 1L and the right side plate 1R.

  The left side plate 1L and the right side plate 1R are typically 1.2 mm thick steel plates, and the inner surface of the left side plate 1L is itself separated from a ball valve, cheese, and air via a conventional support member. In order to attach each necessary equipment such as a pressure tank, it is preferable to arrange reinforcing rib projections 1G on the sides LS1 and LS2 and the corner side 1A of the left side plate 1L as shown in FIG.

Therefore, the heater unit box 1 can be easily assembled and separated by fitting and screwing the upper lid 1U and lower lid 1D with the left side plate 1L and the right side plate 1R, and the storage devices are attached only to the left side plate 1L. Therefore, maintenance such as inspection, repair and replacement is easy.
The presence of the anchor piece 1C and the abutment anchor piece 1F improves the workability of attaching the right side plate 1R to be removed during maintenance to the left side plate 1L, and the anchor piece 1C and the abutment anchor piece 1F are used to reinforce the box 1. It also plays a rib function.

  As shown in FIG. 6, the air separation pressure tank 2 disposed in the heater unit box 1 includes a lower side 2D, a front side 2F, a rear side 2B, an upper side 2T, and both side sides 2L and 2R, and the upper side 2T is the front side. It is a box shape that is continuous with the front side 2F at the inclined side Sf and the rear side 2B at the rear side inclined side Sb, and the connection port J1 is connected to the upper and lower central part of the front side 2F, and is connected to the upper and lower central part of the rear side 2B. The port J2 is provided with a connection port J3 at the rear part of the upper side 2T, and the two blades 2A and 2A 'inclined and raised backward are formed between the two sides 2L and 2R. The rear blade 2A 'is disposed at a position corresponding to the lower side of the upper side connection port J3 at a position corresponding to the rear side of the connection port J1 on the front side.

In this case, the capacity of the air separation pressure tank 2 depends on the amount of water charged in the circulating heating system at normal temperature (standard: 15 ° C.) and hot water (standard: 80 ° C.), and the amount of expanded water. Calculated and determined from the air pressure in the tank 2, the positions of the connection ports J1, J2, and J3 are such that the connection port J1 and the connection port J2 are below the water level even when the heater unit box 1 is used laterally even at room temperature. In addition, when the heater unit box 1 is used vertically, the connection port J3 and the connection port J2 may be determined to be below the water level.
Further, both the lower blade 2A and the upper blade 2A ′ cause a control turbulent flow for promoting air separation. If the inclination angle is 30 °, the tank can be used vertically or horizontally. The function of generating a controlled turbulent flow that suppresses the natural generation of vortex flow and promotes air separation by a diversion action is generated.

The air separation pressure tank 2 is made of a miniaturized plastic resin and has been developed under the proposition of eliminating the need for an air vent valve and a safety relief valve. Made of resin, the radiators 1 to 3 kw are vertically used, and at room temperature, the amount of water is 0.19 L (liters), the system pressure is 0.01 MPa, the temperature is 80 ° C., the amount of water is 0.26 L, and the system pressure is 0. .04Mpa, in the horizontal use, the water volume is 0.28L, the system internal pressure is 0.01Mpa, the water volume is 0.34L, and the system internal pressure is 0.04Mpa at 80 ° C. at the normal temperature.
If the air separation pressure tank 2 is made of translucent plastic, it can be seen from the outside, and the water entering the tank can be visually observed when filling the circulation heating system. Convenient for maintenance.

  Therefore, in the air separation pressure tank 2 of the present invention, the two slats 2A and 2A 'are used as a control turbulent flow effective for air separation when the two blades 2A and 2A' are used in the vertical and horizontal directions. In combination with the rapid decrease in the flow velocity in the tank, the air bubbles in the water are preferably raised and separated, and the generated air in the circulation system is safely secured in the air separation pressure tank 2. An air separation pressure tank that does not require the arrangement of a conventional safety relief valve and an air vent valve is provided, and one heater of the entire circulation system excluding the radiator of the conventional example 1 (FIG. 9) Storage in the unit box 1, general use of the heater unit box 1 in vertical or horizontal use, and miniaturization of the heater unit box 1 are possible.

Further, in the present invention, when the rectangular heater unit box 1 is used in a vertical arrangement as shown in FIG. 2, the front side 2F of the air separation pressure tank 2 is on the upper side and the rear side 2B is on the lower side. Preferably, the pipe heater 4 is connected to the connection port J3 on the upper side 2T, the forward pipe S is connected to the connection port J2 on the rear side 2B, and the connection port J1 on the front side 2F is closed with the cap 2C. .
In this case, the path connection between the connection port J3 and the pipe heater 4 and between the connection port J2 and the forward pipe S may be connected by an ethylene-propylene rubber (EPDM) pipe.

Accordingly, in the air separation pressure tank 2, as shown in FIG. 6D, the circulating water is at the water level of wL ₁ at normal temperature and at the water level of wL ₂ at 80 ° C., and the inflow water Fin from the connection port J3 is reduced. It becomes the effluent Fout from the connection port J2, and the flow velocity rapidly decreases in the tank 2, and the lower slat 2A in the tank 2 flows upward, the downward flow F2, and the upper slat 2A. The upward flow F3 and the downward flow F4 are separated, and the air bubbles in the water are separated and raised to the air zone Za at the upper part of the tank closed by the cap 2C, and the heat radiating portion 8 does not contain air. Hot water can be circulated.
Therefore, even if the air separation pressure tank 2 of the present invention is used in a vertical arrangement as shown in FIG. 6 (D), the functions of the sealed expansion tank and the air separator of the conventional example 1 (FIG. 9) are exhibited. The heater unit box 1 can be downsized.

Further, when the rectangular heater unit 1 is used in a horizontal arrangement, the upper side 2T of the air separation pressure tank 2 is arranged on the upper side and the lower side 2D is arranged on the lower side, and a pipe is connected to the connection port J1 on the front side 2F. It is preferable that the heater 4 is connected, the forward pipe S is connected to the connection port J2 on the rear side 2B, and the upper side connection port J3 is closed with the cap 2C.
In this case, the connection port J1 and the pipe heater 4 and the connection port J2 and the forward pipe S may be connected by an ethylene-propylene rubber pipe.
And since the connection port J3 of the upper side 2T is airtightly sealed with the cap 2C, the lower area of the connection port J3 of the tank 2 becomes the air region Za.

Therefore, as shown in FIG. 6 (C), the air separation pressure tank 2 becomes the water level of wL ₁ when the circulating water is at room temperature (15 ° C.), and the water level of wL ₂ at 80 ° C. The circulating inflow water Fin flows into the tank 2 from the connection port J1, and the inflow water whose flow velocity is reduced is divided into the upper flow F1 and the lower flow F2 by the front blades 2A, and the air bubbles in the flowing water are separated and raised. The rear slat 2A ′ also divides into the upper flow F3 and the lower flow F4, and separates and raises the air bubbles generated from the flowing water into the air region Za at the upper part of the tank, thereby becoming the circulating effluent Fout. To the forward pipe S from the connection port J2.

  Then, the connection port J3 on the upper side 2T is closed with a cap 2C, and since the circulating water system is an open type in the air region Za in the upper part of the tank 2, the increase in heating expansion pressure is very small. As shown in FIG. 6C, the function of the sealed expansion tank and the air separator of the conventional example 1 (FIG. 9) is exhibited with safety while being used in a horizontal arrangement, and the heater unit box 1 is downsized. Is possible.

Further, the humidifying tank 12 of the present invention is a vertical cylinder in which a moisture releasing cap 12C having a moisture releasing hole H12 is detachably attached to the top, and is erected on the side end of the radiator HR, with the lower end at the warm water return path. The water level in the humidification tank 12 is preferably visible.
Since the humidifying tank 12 has an open shape at the upper end in the hot water circulation path, the water surface in the tank 12 needs to constitute a trap that prevents air from entering the hot water circulation path. Since the water level of the working tank 12 is lowered by the moisture releasing action, it is necessary to maintain the trap function.
In this case, as shown in FIG. 7, the humidifying tank 12 houses the pipe P8 of the transparent pipe 5D in a square pipe 12F having a window 12A, and a moisture releasing cap 12C is detachably attached to the upper end of the square pipe 12F. Just do it.
Therefore, if the humidifying tank 12 is in the form of a vertical cylinder on the side surface of the radiator HR, the fluctuation of the water level surface due to moisture release can be visually confirmed at a glance, and the supply of water into the humidifying tank 12 is also moisture-releasing. It can be easily carried out by removing the cap 12C.

In addition, the humidifying tank 12 'has a second air separation pressure tank 2 arranged in the warm water return path in the form of an auxiliary tank in the horizontally arranged heater unit box 1 and is located above the connection port J3 on the upper surface. It is preferable that a cylinder part 12D protrudes from the surface of the right side plate 1R of the heater unit box to be mounted, and a moisture release cap 12C having a moisture release hole H12 at the upper end of the cylinder part 12D is detachably attached.
In this case, the air separation pressure tank 2 can be diverted as the humidifying tank 12.
And although the water level in the humidifying tank 12 is complicated, the air separation pressure tank 2 itself has a large capacity. The risk of loss is avoided.

The air separation pressure tank 2 is arranged in the hot water circulation path of the heater unit box 1 and is a novel tank that does not require the expansion tank, air separator, drain valve, and safety relief valve of the conventional example 1 (FIG. 9). Therefore, an example of a 1 to 3 kw heating tank will be described.

  The air separation pressure tank 2 is a semi-transparent plastic resin (polyethylene resin) molded product having a general wall thickness of 0.6 mm, and is a pressure resistant tank of 0.12 Mpa with an internal volume of 0.5 L. 6 (C), the lower part has a box shape with a length (L2) of 140 mm, a height (h3) of 55 mm, and a width (W2) of 50 mm, and the upper part has a width (W3) of the upper side 2T of 38 mm. In the truncated pyramid shape with a length (L3) of 70 mm and a height (h4) of 30 mm, the opposing front side 2F and rear side 2B are 30 mm above the lower end (d5) and are centered in the width W2. In the upper side 2T, connecting ports J1, J2, and J3 having an outer diameter of 13 mm, a thickness of 0.5 mm, and a length of 20 mm are projected at the center of the width W3 and 55 mm (L5) from the rear side 2B. It is a thing.

Each connection port J1, J2, J3 has two projections 2G with a width of 1 mm and a projection height of 0.5 mm arranged at intervals of 6 mm in order to ensure the attachment of piping pipe 5A or cap 2C. To do.
In addition, as shown in FIG. 6C, in the tank 2, a front blade 2A and a rear blade 2A ′ are arranged in a passing manner on the left side 2L and the right side 2R.
