Description

Portable Small Hot Water Boiler for Heating {SMALL-SIZE HOT-WATER BOILER FOR HEATING A ROOM}

The present invention relates to a portable small hot water boiler for heating.

More specifically, the structure of the boiler mechanism is simplified and downsized by a system for heating under a condition of keeping the temperature difference between the heating portion and the heat radiating portion of the heat medium small.

This is not a miniaturization by reducing the design standard of a simple boiler component, there is a characteristic difference that makes the boiler simplified and miniaturized by the structural technical means of the boiler.

In recent years, local independent heating has been implemented in each room or bed.

That is, the heat pipes are independently piped in each room to be heated by an independent hot water boiler, or the hot water pipes are arranged on a mattress for each bed to heat the present invention. The present invention relates to a technical field of heating by a heat medium, and to a heating wire such as an electric blanket. Is distinguished from heating.

An object of the present invention is to enable the heating medium to achieve the simplification and miniaturization of the boiler mechanism by a system for heating and circulating and heating while keeping the temperature difference between the heating section and the radiating section small.

Still another object of the present invention is to provide a sealed hot water boiler which is very easy to handle, easy to use, and safe in local independent heating such as bed heating.

The conventional heating system heats water at 60-70 ° C. in a heating part, then transfers the heat to a heat dissipation part, radiates it to cool down to about 30 ° C., and then cools the water to the heating part. It is heated to reflux and heated again, and then repeatedly circulated to the heat radiating unit and heated.

At this time, the heating time of the heat medium and the heat dissipation time of the heated heat medium are relatively long, the circulation cycle of the heat medium is slow, and the amount of hot water is relatively large because of the balance of the heating time and the heat dissipation time.

In the conventional heating system, there is a difference depending on the size of the room, but in the case of a typical home cold room, the total amount of hot water is about 15 liters or more when piping a hot water pipe with an inner diameter of about 10 mm to a length of 20 m. There is a limit to the small design. Therefore, when the hot water boiler is installed indoors, the occupied space of the boiler is large and the handling of transportation is inconvenient, and the production cost of the boiler is also high.

The present invention has corrected the conventional problem that there is a limit to downsizing the hot water boiler mechanism, and adopted a new heating system in order to further downsize the boiler mechanism.

That is, the heating medium can achieve the simplification and miniaturization of the boiler mechanism by the system of heating and circulating and heating while keeping the temperature difference between the heating section and the radiating section small. In other words, in order to keep the temperature difference between the heating part and the heat dissipating part small, the cycle of the cycle of the heat medium must be short, and the heating amount of the heat medium must be small to heat the heat medium to the set temperature in a short time. The smaller the heat medium to be heated, the simpler and smaller the structure of the boiler becomes.

For example, if the inner diameter of the hot water pipe is thinned from the conventional 10 mm to 1/2 size at the same length of the conventional hot water pipe (heat radiating pipe), the total amount of the heat medium is reduced to 1/4 and the inner diameter of the hot water pipe is 1 When the thickness is reduced to / 3, the total amount of the heat medium decreases to 1/9, and to about 2 liters. If the heat medium of this capacity is circulated under the condition of being cooled to around 10 ° C. in the heat dissipating part while being heated to 40-50 ° C. in the heating part, the heating part can maintain effective heating only by heating compensation to a temperature cooled to around 10 ° C. . At this time, about 80% of the total amount of the heat medium is distributed to the heat radiating part, so only 300-400㏄ should be heated in the heating part. This small amount of heat medium can be heated to a predetermined temperature in a short time, and the circulation cycle is short, thus effectively heating. You can do it.

In addition, in the above heating system, since the amount of heat medium is basically small, the size of the hot water boiler of the heating part can be configured to be small, and the simple structure of a pipe-type structure that also functions as a pipe through which the hot water boiler is heated in the circulation system of the heat medium is possible. Do. This makes it possible to further reduce the size of the boiler. In addition, the pump also requires high speed rotation of the Inferra, but the pump volume is not large, so the pump can be miniaturized. It is possible to miniaturize the standard by the structural simplification of the boiler and circulation pump by the improvement of such a heating system. In fact, in case of bed heating, portable small hot water boiler of the size of cigarette pack can be constructed.

The hot water boiler apparatus of the present invention is a small size in which a well-known electric heat heater is inserted into a tubular boiler body, which serves as a pipe through which liquid heat medium such as water or vegetable oil circulates, thereby heating the heat medium in circulation to a predetermined temperature. A boiler, a waterproof resin pump that circulates the heat medium rapidly by rotating at 3600 rpm, and a molded waterproof motor pump and a regulator that regulates the pressure of the heat medium are integrally assembled to form a heat medium. During the circulation maintenance, the heat medium circulated in a small amount by the boiler, which is the heating part, is heated and maintained at the set temperature so that the heating medium and the heat dissipation part can be effectively heated with a small amount of the heat medium by maintaining the temperature difference of about 10 ° C. Therefore, the structure of the hot water boiler can be simplified and miniaturized.

Since the hot water boiler of the present invention can be configured in the size of a pack of cigarettes, in independent heating such as a bed, the occupied space of the boiler is negligible and is hermetically sealed, so there is no fear of supplementation or leakage of the heat medium, and thus the safety is high. It is a new sealed hot water boiler for easy handling and more convenient use.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of components of a boiler apparatus of one embodiment of the present invention and FIG. 2 is a perspective view of an assembled boiler apparatus. Here, the boiler mechanism refers to an assembly of a boiler in which a boiler, a pump, and a heat medium regulator are combined.

The boiler apparatus of the present invention is configured to apply a heating system in which a small amount of heat medium rapidly circulates between the heating section and the radiating section so that the temperature difference between the heating section and the radiating section is maintained at about 10 ° C. That is, a boiler (B) having a heat transfer heater built-in inside the tubular boiler body serving as a circulation clearance of the heat medium, and a motor and a pump for rapidly circulating the heat medium between the heating part and the heat dissipating part are integrally molded with synthetic resin. P), and the regulator (R) for regulating the pressure of the heating medium while serving as the support of the boiler (B) and the motor pump (P), are integrally assembled to form a circulation system of the heating medium and are hermetically sealed. Of course, the configuration of the three elements of the boiler, the circulation pump and the regulator is essential in the boiler mechanism, the structure of each element of the present invention and the combination of each element is characteristically different from the conventional one.

Boiler (B) is a tubular body (1) also serves as a customary through which the heat medium circulates, the inlet (1a) of the heat medium is connected to the outlet (2a) formed on one side of the plate body (2) of the regulator (R) by screwing And the heat pipe 1b of the heat medium is connected to the main surface of the rear end of the body 1, and a well-known heat transfer heater 1h to which the cord 1d is connected is longitudinally inside the space of the body 1. And the threaded portion 1s of the heater is screwed to the rear end portion 1c of the body 1 so that the electric conductor 1d is directed outward. The heater 1h and the internal space of the body 1 In between, it becomes the passage 1u of the heat medium w, and the heat medium which moves this path is heated to predetermined temperature by the electric heat energy of the heater 1h. A heat sensing element 1t is attached to the main surface of the body 1 to provide a temperature controller (not shown) to control the temperature of the heat transfer heater 1h by a power source in accordance with the heating conditions of the heat medium.

The plate-like body 2 of the regulator R is formed with a rectangular chamber 2c covered with a lid 2v, and also serves as a support plate for mounting the boiler B and the motor pump P. The inlet port 2i of the pump and the discharge tube 2d are formed in the chamber 2c of the body 2, and the outlet port 2a of the discharge tube 2d communicates with the inlet port 1a of the boiler body 1. do. In addition, an inlet port 2b through which a reflux tube 2t is connected is formed at one side of the lower side chamber 2c in which the boiler body 2 is welded, and is introduced into the chamber 2c through the reflux tube 2t at the heat dissipation unit. The pressure of the heating medium w is in equilibrium in the chamber 2c of the expansion space. At one upper end of the chamber 2c, an injection hole 2j of a heating medium is formed and sealed with a stopper 2k.

The body 3 of the waterproof motor pump P is an integral type molded in a rectangular block as a synthetic resin such as polyurethane or polystyrene. The stator 3s on which the coil 3c of the motor m is wound is molded with synthetic resin in the cylindrical space of the rotor chamber 3a so that only the conductor wire 3d of the motor is observed outside and is located at the center of the rotor chamber 3a. The support shaft 3x protrudes, and the rotor 3r of the two-pole motor made of permanent magnets and the inferor 3f of the pump P are integrally coupled to the tubular support shaft 3y, and the tubular support shaft 3y ) Is inserted into the support shaft 3x protruding from the rotor chamber 3a so that the rotor 3r is located in the rotor chamber 3a of the stator 3s and the inferor 3f of the pump P is the pump chamber 3p. The motor body 3 of the motor pump is coupled to the plate-like body 2 of the regulator by a screw tube 2p and a bolt 2q, and is rotated at a rotational speed of 3600 rpm by the magnetic force of the stator 3s. 3r) rotates with the infra 3f of the pump chamber 3p to impart fluidity to the circulation system of the heat medium.

In addition, since the rotor chamber 3a and the pump chamber 3p communicate with each other, the assembly of the inferior and the rotor is easy, and even if the heat medium flows into the rotor chamber, it is waterproof so that there is no effect on the function of the stator.

The boiler apparatus is covered with a box-shaped cover (4). The cover (4) is provided with a switch (5), a thermostat (6), a power cord (7) having a socket (7a), and an electric heater of the boiler (B). (1h), motor pump (P), temperature sensor (1t) and the like are electrically related.

Figure 6 uses both ends of the heat dissipation pipe (d) arranged in the mattress (M) of the bed in contact with the return pipe (2t) and the outflow pipe (1b) discharged to the outside of the cover (4) of the boiler mechanism, regulator (R) Inject the appropriate heat medium (w) such as water, vegetable oil or antifreeze into the chamber (2c) through the inlet (2j) to fill the heat dissipation tube (d) and the chamber (2c), but with a slight margin in the chamber (2c). Leave the space empty and seal the inlet (2j) with a stopper (2k) to use as a closed type.

Insert the socket (7a) of the power cord (7) into a power socket or outlet (not shown), set the temperature to be heated by the temperature controller (6), and then connect the power switch (5) to ON, the motor pump (P) As the power is applied to the coil 3c of the stator 3s of the motor m, the alternating magnet is configured, and the rotor 3r rotates at a rotational speed of 3600 rpm due to the change of the magnetic pole.

At this time, while the inferer 3f is rotated in the pump chamber 3p, the heat medium w that has been collected in the chamber 2c of the regulator R is sucked in, and then the boiler B is passed through the outlet 2a through the discharge port 2d. It flows into the fuselage 1 of).

The heat medium flowing into the boiler body 1 is heated to a predetermined temperature set by the electric energy supplied to the heat transfer heater 1h while passing through the passage 1u. The heating temperature of the heater 1h is usually 60-70 ° C., and the heating temperature may be adjusted by the required heating temperature of the heat dissipation unit, that is, the mattress M.

At this time, since the temperature difference between the heat dissipating part and the heating part is about 10 ° C., the heating temperature may be about 50 ° C. if the heating temperature is 35 ° C.

Since the fuselage 1 of the boiler is a tubular body that plays a role of clearance through the pumping pressure of the pump P, the heat medium of the liquid flowing into the inlet 1a is a heat dissipating tube of the mattress M which is a heat dissipating part through the outlet pipe 1b. It is circulated to (d) and then flows back into the chamber 2c of the regulator R through the return pipe 2t.

In the case of a single mattress, the total heat medium is about 1.5 liters and 80% of the heat medium is distributed in the heat sink (d) of the mattress (M), so the heating capacity of the tubular boiler body (1) is about 200-300㏄, so that Heated to the desired set temperature.

In addition, the cycle of 1.5 liter of heat medium circulating the heat radiating tube (d) of about 20m in length is about 2 minutes and at first it takes about 10 minutes to reach the set temperature. Since the temperature drop in the part becomes about 10 ° C in 2 minutes, if only the temperature is compensated by the temperature of 10 ° C dropped in the heating part, it is effective while maintaining the temperature difference between the heating part and the radiating part within 10 ° C by the circulation of the pump. Can be heated.

If the temperature drop in the heat dissipation unit is high, the heating temperature of the heating unit may be increased to a corresponding temperature.

Boiler body with electrothermal heater is made of pipe that doubles the heat medium's clearance, so the fluid resistance is low and the heat medium is easily flowed by the pumping pressure of the pump. Since the heating amount of the heat medium is small, miniaturization is possible.

Since the heating cycle of the heat medium is smaller than the heating amount of the heat medium in the boiler, the temperature difference between the heating part and the heat dissipation part can be kept small, and the heating time of the heat medium is shortened by only compensating for the insufficient temperature in the heating part. The temperature can be kept almost uniform.

In addition, the motor pump is molded with a synthetic resin to form an integral block, so that the assembly is easy and the heating medium can continue the pump function without inhibiting the electric operation of the motor.

Tubular boilers and block motor pumps are integrally combined with regulators, and the boiler's heating amount is small, so the structure can be simplified and downsized, and production cost can be produced at low cost.

In addition, the boiler is easy to carry and handle, and its closed type ensures high safety without the risk of leakage of heat medium and is easy to use so that the space occupied by the boiler can be neglected. Compared with the above, there are various effects such as being more convenient to use.
