Description

Powerless boilers {BOILER OF NO NEEDED ROTATION POWER}

The present invention relates to a non-powered boiler, and more particularly, to a non-powered boiler capable of evenly heating the heating object by circulating water smoothly in the heating hose.

The non-powered boiler is composed of a water tank for storing water, a heating tank supplied with water from the water tank, a heating hose connected to the heating tank, and a heating means for heating the heating tank.

In the conventional non-powered boiler having such a configuration, there was a "portable hot water boiler", which is registered utility model No. 193222 (utility model application No. 2000-9005, hereinafter referred to as "quoting citation").

However, the above-mentioned proposal is that when the heating tank is heated by the heating means, water in the heating tank circulates through the heating hose to the reservoir. After a certain time, the upper area inside the heating tank is filled with steam evaporated with water and the steam is circulated. At this time, the steam flows well to the place where the air or steam in the heating hose, but when it meets the water accumulated in the heating hose, the latent heat of steam is diverted to the water is not circulated smoothly in the heating hose. Thus, there is a problem that the heating of the heating object is not uniformly made.

In addition, the electric plate can easily heat the heating object by allowing electricity to flow to the heating object. However, electromagnetic waves are generated in heating objects, and electromagnetic waves have been reported to be harmful to humans, and efforts have been made to reduce such electromagnetic waves.

The present invention is to solve the problems of the prior art as described above, the object is to circulate the water smoothly in the heating hose is heated heating object evenly.

Still another object of the present invention is to be able to heat a heating object without generating electromagnetic waves.

The non-powered boiler according to the present invention includes a water tank containing a predetermined amount of water; A heating tank positioned below the reservoir and receiving water from the reservoir; One end is connected to the lower center of the water reservoir and penetrates the upper center of the heating tank, and the other end is located inside the heating tank, and a check valve is interposed so that water does not flow back from the other end to the one end. With connector; A discharge pipe positioned at one end near the inner bottom of the heating tank and penetrating the upper one side of the heating tank; A heating hose having one end connected to the other end of the discharge pipe and passing through a heating object such as a sleeping bag, a blanket or a sheet; An inlet pipe having one end connected to the other end of the heating hose and the other end connected to the reservoir; And heating means located at an outer bottom of the heating tank and / or inside the heating tank.

As the heating tank is heated, the one end of the discharge pipe is preferably bent in a U shape in order to suppress the generation of steam in the water and into the discharge pipe.

Preferably, the other end of the connection pipe is located near the bottom surface of the heating tank so that water supplied from the reservoir through the connection pipe is located near the bottom of the heating tank.

The inlet pipe is connected to the lower portion of the reservoir and the check valve is preferably interposed so that the water in the reservoir does not flow back to the heating hose. As a result, when the internal pressure of the heating tank is lowered, the water of the reservoir is prevented from flowing through the heating hose.

When the set temperature of the heating object is higher than the detection temperature of the heating object, the heating means is preferably turned on / off periodically so that water is smoothly supplied from the reservoir.

Hereinafter, with reference to the drawings will be described in detail. However, these drawings are for illustrative purposes only and the present invention is not limited thereto.

1 is a schematic diagram of a non-powered boiler according to the present invention.

Referring to FIG. 1, a non-powered boiler includes a reservoir 10 containing water, a heating tank 20 for receiving water from the reservoir 10, and water supplied from the heating tank 20 for a predetermined section of flow. And a heating hose 52 for discharging water to the reservoir 10 and a heating means 70 for heating the heating tank 20.

The reservoir 10 is open at the top and covered with a cover (not shown) at the top. The cover may be perforated. The water of the reservoir 10 is in a state in which atmospheric pressure is applied by a gap between the upper portion of the reservoir 10 and the cover or a hole drilled in the lid. In addition, the water reservoir 10 and the cover may be integrally formed to provide a water supply unit for supplying water. In this case, when the water supply unit is sealed, atmospheric pressure does not act on the water of the water tank 10. . Holes in the water replenishment may cause atmospheric pressure to act on the water in the reservoir 10. In the conventional non-powered boiler, if the atmospheric pressure does not act on the water in the reservoir 10, the boiler does not operate (heating object is not heated), but in the present invention, because the power is applied as shown in Figure 3 (b) the reservoir 10 The boiler is operated (heating object is heated) even if there is no atmospheric pressure on the water inside.

The heating tank 20 receives water from the reservoir 10 through the connection pipe 30. The outer surface of the heating tank 20 has a heat insulating portion (not shown) for reducing the heat loss to the outside. It is preferable that the heat insulation part has a small thermal conductivity.

The connection pipe 30 is formed from the lower center of the water storage tank 10 to the vicinity of the bottom surface of the heating tank 20 through the upper center of the heating tank 20. Accordingly, the water supplied from the reservoir 10 may flow near the bottom surface of the heating tank 20. In addition, a check valve 32 is interposed in the connecting pipe 30 to prevent water from flowing back from the heating tank 20 to the water storage tank 10.

The check valve 32 operates according to the pressure. That is, if the pressure acting from the reservoir 10 to the heating tank 20 is greater than the pressure acting from the heating tank 20 to the reservoir 10, the water flows from the reservoir 10 to the heating tank 20. However, if the pressure acting from the reservoir 10 to the heating tank 20 is less than the pressure acting from the heating tank 20 to the reservoir 10, the check valve 32 is a water tank from the heating tank 20 Block backflow to (10).

The heating tank 20 is formed with a discharge pipe 40 through which the water supplied from the reservoir 10 is discharged. One end of the discharge pipe 40 is protruded to the upper portion of the heating tank 20 and the other end is bent in a U-shape while being located near the bottom of the heating tank 20 of the heating tank 20. Here, the other end of the discharge pipe 40 is located near the bottom surface of the heating tank 20, thereby preventing the steam present in the upper region of the heating tank 20 from entering the discharge pipe 40. In addition, the other end of the discharge pipe 40 is bent in a U-shape, the steam is mainly generated at the bottom when the heating tank 20 is heated, the steam is prevented from entering the discharge pipe 40 while rising.

The heating hose 52 passes through a heating object 52 such as a sleeping bag, a blanket, or a blanket, and one end is connected to the discharge pipe 40 protruding from the upper portion of the heating tank 20, and the other end is connected to the lower region of the reservoir. It is connected to the inlet pipe (60). At this time, the water flows from one end to the other end while the energy of the water is delivered to the heating object (52). The heating hose 52 is preferably freely deformable according to the shape change of the heating object 52, such as a tube made of silicon.

The inlet pipe 60 is located at the bottom of the reservoir 10 and has a check valve 62 inside the inlet pipe 60. The check valve 62 prevents water from flowing back from the reservoir 10 to the heating hose 52. The inlet pipe 60 may be located above the reservoir 10, in which case the check valve 62 may not be provided.

The heating means 70 is located on the outer bottom of the heating tank to heat the heating tank 20. Here, the heating means 70 may heat the water while being located inside the heating tank 20 or in the circumferential region of the heating tank.

The controller 80 controls the heating means 70 on / off by comparing the detected temperature of the heating object 52 with the set temperature of the heating object 52.

The detection temperature of the heating object 52 is the temperature of the heating object 52 measured by the detection unit 82, and the set temperature of the heating object 52 is a temperature at which the user intends to heat the heating object 52. Here, the set temperature is set by the setting unit 84. Although the setting unit 84 is positioned in the heating object 52 in the drawing, the setting unit 84 may be positioned in the control unit 80.

In addition, the detection temperature of the detection unit 82 and the setting temperature of the setting unit 84 are transmitted to the control unit 80 through the wire. Here, the setting unit 84 may be located in the heating tank 20 or the heating means 70. In addition, the detection temperature of the detection unit 82 and the setting temperature of the setting unit 84 may be transmitted to the control unit 80 by communication.

On the other hand, in order to prevent the explosion risk of the heating tank 20, a safety valve may be provided in the heating tank 20.

2 is a flowchart of operation of a non-powered boiler according to the present invention.

Referring to Fig. 2, the operation flow of controlling the ON / OFF of the heating means 70 while setting the heating temperature by the non-powered boiler and detecting the temperature of the heating object 52 is according to the following. same.

[Heating temperature setting (set temperature) (S10)]

The temperature at which the heating object 52 is to be heated is set in the setting unit 84.

[Timer operation set ON / OFF (S20)]

Start a timer that repeatedly turns ON and OFF. When the timer is activated, the predetermined time is turned ON and the predetermined time is turned OFF to continuously repeat the operation.

[Heating object temperature detection (detection temperature) (S30)]

The detector 82 detects the temperature of the heating object.

Is the timer in the ON position? (S40)

It is determined whether the timer is in the ON position or in the OFF position. If the timer is in the ON state, step S50 is performed. If the timer is in the OFF position, step S60 is performed.

[Heating means OFF (S50)]

The heating means 70 is turned off by cutting off the power supply of the heating means 70. Then, the step (S30) of detecting the temperature of the heating object 52 is performed. At this time, water is supplied from the reservoir 10 to the heating tank 20 in the state in which the heating means 70 is turned off.

[Setting temperature> Detection temperature (S60)]

The set temperature S10 set by the setter 84 is compared with the detected temperature S30 detected by the detector 82. If the set temperature is equal to or lower than the detection temperature, step S50 is performed. If the set temperature is higher than the detection temperature, step S70 is performed.

[Heating means ON (S70)]

The heating means 70 is turned on. At this time, since the temperature and the internal pressure of the heating tank 20 is high, water is prevented from flowing through the connecting pipe 30 from the reservoir 10 and water flows to the heating hose 52 through the discharge pipe 40. Done.

Figure 3 (a) is a view showing a change over time of the power source in a conventional electric blanket, Figure 3 (b) shows a change over time of the power source for operating the heating means in a non-powered boiler according to the present invention. Drawing. Herein, a state in which power is supplied is called ON, and a state in which power is stopped is called OFF.

Referring to FIG. 3A, the power source for continuously operating the electric field until the set temperature and the detection temperature are the same (point 's' in FIG. 3) is ON. After that, the power source is repeatedly turned ON / OFF.

Referring to FIG. 3 (b), as described in the operation flowchart of FIG. 2, the power source for operating the heating means 70 until the set temperature and the detection temperature become the same initially (the 'p' point in FIG. 3). Will repeat ON and OFF repeatedly. At this time, the water is heated while the water is circulated to the heating hose 80 while ON, the heating tank 20 while the OFF (OFF) is smoothly supplied with water from the reservoir (10). Therefore, when the conventional electric grid is powered on the non-powered boiler, the heating tank cannot be smoothly supplied with water from the reservoir, but the present invention smoothly supplies water from the reservoir to the heating tank.

As described above, according to the present invention, since the inflow of steam to the heating hose is suppressed, the water flows smoothly, and the heating object is evenly heated. Unlike the conventional electric blanket, electromagnetic waves are not generated in the heating object. .

In addition, the non-powered boiler of the present invention has the effect that the water is smoothly supplied from the reservoir tank to the heating tank while the heating tank is repeated (ON) and (OFF).
