Description

Portable Water-Hot Boiler

The present invention relates to a portable hot water boiler having a hot water circulation function using a supplemental water cistern as a heat exchanger, and more particularly, to a portable hot water boiler having a hot water circulation function, The hot water boiler is a type of hot water boiler in which the replenishment water reservoir for circulating circulation water for continuous supply is separated into the upper part or the outer part, and the heat transfer supplement water reservoir is separated and separated to minimize the consumption of heat source, shorten the heating time, The hot water of high temperature and high pressure in the discharge portion is attenuated to a comfortable temperature and supplied to the hot water mat, and water is automatically supplied to the hot water tank by using the vacuum pressure to condense the steam in the heat exchange pipe Effective hot water booster to increase thermal efficiency and suppress noise by supplying structure It relates to Russia.

Generally, the portable hot water boiler has a circulation pump type and sensor control type using electricity, and the boiler which does not use electricity is manufactured in various forms such as a method of heating directly to the spiral coil type pipe and a method of using the pressure pipe by heating steam, It is made of hot water boiler.

On the other hand, outdoor activities such as camping and fishing are increasing due to the recent leisure activities due to the five-day workweek system. As a means of keeping warm in outdoor activities, the use of boilers using hot water mat, And the use of hot water mat as an auxiliary heating device is increasing day by day at home.

However, the conventional electric hot water boiler is disadvantageous in that it is inconvenient and uneasy because it can not operate because of no hot water circulation without electricity in case of power outage due to disaster or electricity in outdoor activities.

In addition, a conventional portable non-powered boiler that does not require electricity supplies hot water by heating the coiled piping or by heating the hot water. Since hot water supplied is directly connected to the hot water mat, hot water flows into the hot water mat, , Which causes problems such as a risk of burns due to an increase in the temperature of the discharged water, generation of noise of the hose inner hose, circulation due to the air in the hose, or weak circulation.

In addition, the conventional portable non-powered boiler devices have a large size or coupled with a water bottle, which slows down the temperature rise of the heat bar, which takes more time to generate steam, The amount of fuel consumed is large.

However, in most existing portable non-powered boilers, the check valve of the receiving portion of the heating cylinder is opened by using the hydraulic pressure of the water bucket during operation. In this case, the size of the water bucket is increased and increased for high water pressure. And it is inconvenient for outdoor activities such as increase in the amount of water which is difficult and necessary.

In the case of the boiler type which directly heats to the coil type pipe, the coil pipe is weakened due to repeated oxidation of heat concentrated in the local part due to the characteristic of the heat source using the form in which the heat source is directly heated to the coil pipe. And if it is left unused in cold weather, there is a problem that the air layer is small and damage due to the frost wave may occur.

Most of the outdoor boilers use a mixture of antifreeze when used for preventing the freeze, and there is a problem that it may cause natural damage because it is discarded together with water without being recovered after being used outdoors. Therefore, there is a need to prevent freezing of the boiler.

Accordingly, the main purpose of the present invention is to automatically circulate water by the thermal power of a heat source without circulating apparatus using electricity such as a circulation pump, and to control the circulation speed and frequency of water according to the intensity of the heat source

Another object of the present invention is to use the makeup water reservoir as a heat exchanger to maintain the temperature of the discharge part at a predetermined temperature of 80 degrees Celsius or less, thereby preventing the risk of burns, noise caused by the steam in the hose, .

Another object of the present invention is to utilize the main body replenishing water reservoir as a heat exchanger to utilize the depressurization phenomenon which is condensed when the steam passes after the water passes through the pipe, and the check valve of the outlet portion is blocked while generating the vacuum pressure in the pipe, The valve is for the automatic replenishment of the hot heat barrel with open interaction.

Since the check valve is opened by the condensation pressure in which the steam is liquefied in the heat exchanger, not the method of opening the check valve on the intake side by the hydraulic pressure difference, the size of the makeup water reservoir is small so that the volume is minimized, And even if the height of the replenishing water tube is located at the side other than the upper side, the water is automatically supplied by the contraction action by heat exchange, so that the structure of the replenishing container can be variously applied.

In addition, it is an indirect heating type by heat exchange, not a form in which the makeup water bottle is directly heated, but the advantage is that the water temperature is maintained at a predetermined temperature of 80 ° C or below and is not boiled and closed with a lid, have.

It is another object of the present invention to provide a method for preventing freezing of an internal heating oven due to the use of a boiler during cold weather and preventing freezing of the pipe by providing an air layer in the upper part of the heating oven to prevent the heating oven wave, It is connected with flexible hose to prevent the pipe and valve from freezing.

Finally, another object of the present invention is to provide a floor heating device, which has a floor surface wide and flat so as to be able to use various heat sources easily obtainable from the surroundings, in addition to a heat source such as a gas burner, Various heat sources can be easily utilized.

In order to achieve the above object, a hot water boiler according to the present invention is provided with a replenishing water reservoir for receiving hot water of high temperature and high pressure, A plurality of helically wrapped inner tubes are arranged to make hot water of high temperature and high pressure coming out of the heating tube to heat exchange with the replenishing water, and a flexible hose for preventing frost is formed in the pipe, After the check valve is constructed, a hose connection port is provided in the supplementary water cistern to easily connect the boiler mat and the supplement cistern connection to supply the hot water. The return water passing through the boiler mat flows back into the supplement cistern through the supplement cistern connection port, Steam is condensed as it passes through the heat exchange pipe inside the makeup water reservoir, and when the vacuum pressure At this time, the check-back check valve for intake which is installed in the supplementary water cistern is constituted in the upper part of the heating cistern. When the check valve is opened, the supplement water flows back into the heating cistern at a high flow rate. When the supplement water rises to a certain water level, The temperature and the pressure of the tub rise, and the hot water is introduced again through the outlet pipe located at the lower part of the heating cylinder, so that repeated and continuous circulation is achieved.

According to the present invention, a pipe for heat exchange is provided in the supplement tube, so that the hot water and the steam, which have passed through the heat tube, are heat-exchanged with water in the supplement tube and can supply an appropriate temperature of 80 degrees Celsius .

In addition, according to the present invention, it is possible to provide a backflow preventive check valve on the inlet and outlet sides so that water can be continuously supplied to the heating cylinder, and the vacuum pressure generated in the condensing operation of the steam passing through the heat exchange pipe installed in the supplement cylinder, The check valve of the automatic check valve is automatically opened and closed.

Preferably, according to the present invention, the heat-transfer-replenishing-tank connecting portion and the connecting pipe are sealed with a metal material having a high thermal conductivity to help heat exchange, minimize noise generated by steam, and minimize noise caused by steam hammer .

As described above, the hot water boiler of the present invention maintains the temperature of the hot water mat at 80 degrees Celsius or below to allow pleasant heating and prevention of burns. It also enhances circulation efficiency by eliminating water vapor and bubbles as much as possible, .

In addition, since the heat and replenishing water cans of the present invention are separated and installed, hot water and steam generation can be heated more quickly without interfering with the heat and replenishing water cans, so that the fuel saving due to the heating efficiency increase and the generation time of hot water and steam It is possible to shorten the time required for the operation.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention unclear.

1 to 4, the hot water boiler according to the present invention includes a hot water boiler replenishing water bottle 100 for hot water storage and heat exchange for heating, And a hot water mat 200 composed of a flexible pipe 110 for heating and a heating pipe.

Water is replenished to the replenishing water cistern 100 up to the standard water line 130 and water is flowed into the heating water line pipe 30 seconds after the water is replenished, and water flows into the heating water tank inside the heating drum up to the maximum water level 112, Water is supplied to the lower end of the discharge pipe 111. At this time, a mat hose is connected to the mat outlet connecting portion 106 and a hose is connected to the mat return connecting portion 105. When heat is applied to the heat source 140, Water is expanded into the heat exchanging pipe 111 through the heating pouring water outlet pipe 111 while the water is expanded in the inside of the hot water mat 110 and the water is heated by the hot water mat 200 through the outlet pouring check valve 102, Will flow into

At this time, if the water is replenished to the replenishing water bottle 100 by the amount of water flowing into the hot water mat only once during the first operation, the water is circulated smoothly without needing any additional replenishment.

In addition, since the hot water is not filled in the heat exchange pipe 101 at the first operation, a slight bubble noise is generated while passing through the pipe, and steam is introduced into the hot water mat 200. However, Intake is stable and initiates continuous cyclic action.

If the hot water in the heating drum 110 is discharged to the heating / discharging water discharge pipe 111, only the high-pressure steam is supplied into the heating drum 110 And the hot steam flows to the heat exchange pipe 101 along the heating pouring water outlet pipe 111, it rapidly cools while exchanging heat with the makeup water contained in the supplementary water pourer. At this time, The water outlet check valve 102 is shut off and the water inlet check valve 103 is opened to allow the water to flow into the heating cylinder 110 at a high flow rate.

At this time, when the primary water flows in and comes into contact with the bottom surface of the heating cylinder 110, a stronger vacuum pressure is generated so that the inlet portion check valve 103 is fully opened and the water in the supplement cylinder 100 And is sucked into the heating cylinder 110 through the heating cylinder receiving pipe 113.

The water replenishment phenomenon by the vacuum pressure can be applied to other existing hot water boilers in the same manner, but most of the hot water boiler of the present invention is provided with the supplementary water cistern 100), the inlet portion check valve 103 is opened by the vacuum pressure due to the temperature difference, so that it does not occupy a volume due to a large water reservoir for water pressure, And the condensation noise is not generated because the heat exchange pipe 101 is made of a metal pipe.

When the water is heated up to the heating cylinder water pipe level 114 located inside the heating cylinder 110, the water is expanded again by the continuous heat source, and the hot water heated by the heating cylinder water discharge pipe 111 is pressurized And is pushed out into the heat exchange pipe 101. At this time, the inlet portion check valve 103 is blocked so that the fluid does not flow to the opposite side.

If the circulation is smooth due to the heating of the heating cylinder, the boiler firepower is set by regulating the intensity of the heat source 140 to a minimum thermal power or a proper thermal power to control the circulation cycle.

At this time, if the intensity of fire is constantly strong when used indoors

The supply of the circulating water occurs frequently but the temperature of the heat exchange pipe 101 of the supplement tube 100 sharply increases due to the characteristics of the small sized boiler and bubbles are generated on the outer wall of the heat exchange pipe 101, The condensation of steam does not occur and the water supply is not smooth. Therefore, the heat source should be adjusted to a minimum after the first two times of operation, so that the replenishment can be smoothly performed. This phenomenon can be regarded as a weak point of the boiler of the present invention when used indoors, but it is a characteristic of the hot water boiler of the present invention designed to obtain the maximum effect with a minimum heat source. When the operation is performed twice, Even if the fire control is lowered due to the latent heat of the hot water in the hot water mat 200, hot water is continuously supplied to the hot water mat, and lukewarm water passing through the hot water mat is returned to the replenishing water cistern 100, .

In addition, when the apparatus of the present invention is used outdoors, it is necessary to appropriately control the intensity of the fire control according to the influence of the external temperature. Due to the nature of outdoor activities, the temperature of the supplementary water can be maintained at 50 to 75 degrees Celsius It is an advantage of the hot water boiler according to the present invention that it is designed to have a structure in which the operation is good when the outdoor temperature is lowered and the function is not problemous even when it is used in the outdoor activity in winter.

Here, the temperature of the hot water passing through the mat outlet connection portion 106 is 80 degrees Celsius, the temperature of the supplement cistern is also kept at 80 degrees Celsius or less, and the low temperature water passing through the hot water mat, The heat exchanges in the replenishment water cistern, and it goes down to an average of about 75 degrees centigrade.

The heat exchange pipe (101) is wound by a plurality of rollers so as to increase the heat exchange capacity ratio, so that sufficient heat exchange is performed to prevent the steam from being discharged.

The distance between the pipe inlet of the discharge pipe 111 and the bottom of the heating pipe 110 is as close to the bottom as possible so that the discharge water can be sucked up in a short period of time, As much as possible.

If the gap between the discharge tube 111 and the bottom surface of the heating tube 110 is set to be 1 mm or less, the hot water can be discharged smoothly and the steam can flow quickly. If the steam pressure for discharging the hot water continues to rise, it is necessary to heat the bottom of the check valve (100) by the increase of the pipe temperature and pressure due to the vapor pressure 102), shortening the service life of the piping, and causing a cause of overheating of the supplemental water bottle 100 (100) due to the occurrence of noise in the piping. Thus, the height of the bottom of the discharge pipe is not more than 1 mm .

If the inlet shape of the pipe is formed in a shape of 'C' concave / convex like the expansion of the heating / discharging water outlet pipe 111, the defect can be prevented from being firmly attached to the bottom face.

Here, the size of the heating cylinder 110 can be increased or decreased because the entire amount of the fluid can be circulated at one time based on the amount of fluid required in the hot water mat 200 and the function of the cylinder is not affected .

In addition, the size of the replenishing water cans 100 is more than twice as large as that of the heating cans 110, so that the heat exchange of fluids and the excess water are stored, and at least two times of water is required to be stored. It is possible to induce the smooth condensation action of the water in the piping and the quantity of water and the heat exchanging operation.

Although the replenishing water cans 100 are preferably formed on the top of the heating cans 110, even if the replenishing cans 100 are formed outside the heating cans 110 of FIG. 6, they can be deformed because they do not affect the function, At this time, the connection between the replenishing water cans 100 and the heating cans 110 should be closed by connecting the replenishing cans side and the vertical side of the heating cans by horizontal pipe welding or screw fastening, It is not preferable to connect the pipe to induce the discharge of the smooth steam and to operate the supplementary water bottle 100 at the lower part of the heating barrel 110 because it affects the pressure of the water intake part.

The gap between the supplement 100 and the heater 110 is spaced by at least 5 mm so that the high temperature heat of the heater 110 does not directly interfere with the low temperature heat of the supplement 100, The hot water generation in the hot tub and the steam outflow time are prolonged. On the other hand, since the temperature of the hot tub is raised to prevent the heat exchange from occurring, the hot tub may not be refilled. It is preferable to keep the distance of 5 mm or more.

The inlet check valve 103 is also connected to the flexible hose 107 by a flexible hose 107 between the heat exchange pipe 101 and the outlet check valve 102 to prevent freezing and easy valve maintenance. ) To both sides to prevent frost and facilitate maintenance.

Also, considering the volume expansion rate 10% at the time of freezing of water, the heating cylinder water pipe 113

The heating cylinder receiving water level control tube 114 is formed at a point of 10% or more of the upper end of the heating cylinder 110 and the heating cylinder maximum water level 112 can be maintained, To prevent cracking of the heating cylinder (110) due to freezing.

As shown in FIG. 7, the heating water supply pipe 113 is provided with a variable water level control valve 109 so that the water level can be adjusted in the valve, and the height of the heating water can be adjusted according to the size of the hot water mat and the required heating capacity So that hot water can be supplied as much as necessary, thereby achieving efficient heating.

The handle 120, which is connected to the hot water boiler body, is provided with a hose support 121 capable of supporting the hose connected to the hot water mat,

It is possible to prevent cracking and breakage due to the heat of the high-temperature heat source 140 and the heating cylinder 110.

5, the mat connection part 105 and the mat connection part 106 are formed in an 'L' shape 108 on the bottom surface of the supplementing receptacle 100, This type of deformation has no effect on the function, so it can be freely applied to the side or bottom.

The hot water boiler that has been used last can release the hot water mat 200 and the connecting ports 105 and 106 and pour out the water in the replenishing water cans 100 and the heating cans 110. At this time, A small amount of water remains on the bottom surface of the heating cylinder 110. In this case, the water inside the connecting unit 106 can be removed by using a tool or the heating cylinder 110 can be moved to the middle strength of the heat source 140 If the heat source 140 is quickly shut off after heating for about 30 seconds, a small amount of water remaining in the interior is discharged by steam, so that clean storage and rust are not caused and management is facilitated. However, the additional installation of the valve does not apply to increase the weight and volume, and to increase the manufacturing cost.

However, when heat is applied to the pressure cylinder 110, the pipe of the supplement cylinder 100 may not be thawed and may be damaged. Therefore, hot water is poured into the supplement cylinder 100 to heat the heat exchange pipe 101 and the check valves 102, 103 are first defrosted, and then heat is applied to the heating cylinder, the boiler can be normally operated smoothly.

The portable hot water boiler of the present invention provides a function to use various heat sources which are wide and flat on the bottom and can be used for portable purposes, so that it can be easily obtained from surrounding gas stoves, solid fuels, alcohol, gasoline, oil, Coal, briquettes, electric stoves, electric stoves, and the like.

The portable hot water boiler of the present invention continuously supplies hot water of a constant temperature without an electric power source, and always provides a pleasant heating function without worrying about the occurrence of burns and waves.
