Description

Boiler water heater

The present invention provides a boiler hot water supply device which improves the outflow of cold water at the beginning of the use of heating water for kitchen and hot water for bathroom (hereinafter, referred to as hot water). In particular, it relates to a boiler hot water supply device in which each function of such a hot water supply facility is collectively formed in one set module.

10 is an installation diagram showing an example of a generalized boiler heating and hot water supply facility (hereinafter, referred to as a hot water supply facility). The hot water supply facility is configured to switch the heating and hot water supply as the three-way valve 150 for the heating water supplied from the main heat exchange structure for heating the boiler heating water. The hot water supply system is circulated along the heating pipe during heating, and converts the heating water to the auxiliary heat exchanger 110 during the hot water supply, heat-exchanges the heat with the cold water for the hot water, and supplies the hot water to the kitchen and the bathroom.

The conventional hot water supply equipment as described above has a burner 103 installed in a combustion chamber 102 having a flue 101, a water pipe 104 to which water filled by the burner 103 is heated, and forced hot water to be circulated. The circulation pump 120, the hot water flow inlet side is installed on the hot water flow flow detection switch 140 for detecting the hot water flow during the hot water supply, and the pipes 160 provided on the inlet, outlet side of the water pipe 104 -165, and a fuel supply line 180 such as gas and oil, a fuel control valve 170, a bypass pipeline 191, a bypass valve 190, and the like.

Hot water supply inlet having a detection means 343 with a water supply, and having a hot water supply outlet 341 connected to the hot water supply inlet 246 side of the heat exchange means 200, and a second hot water pipe connector 403 ( 342 is formed.

In addition, a second heating tube 350 is positioned between the first heating tube 310 and the switching valve 360 to supply the heating water.

One end of the second heating pipe 350 forms a flange 354 connected to the first flange 364 of the switching valve 360 to be described later and forming the heating outlet 352 and the heating inlet 353. . The second heating pipe 350 is formed with a heating inlet 351 connected to the first heating pipe 310 to receive the heating water, and the second heating pipe connected to the radiator on the heating export port 355 side. The connector 402 is formed.

The switching valve 360 is installed in communication with the heating outlet 248 in order to supply the supplied heating water to a heating pipe such as a radiator or to change the heating water flow when the hot water is concentrated.

The changeover valve 360 starts from a substantially rectangular valve box 361. The heating outlet 352 and the heating inlet 353 formed in the first flange 364 of the second heating pipe 350 are connected to one side of the valve box 361.

That is, when the initial flow of the hot water is instantaneously detected, the signal is transmitted to the motor 321 driving signal which will be described later. As a result, the motor 321 rotates the switching valve 360 to intensively supply the heating water.

The operation of the present invention according to the above structure of the present invention will be described in detail.

4A and 4B are cross-sectional views taken along the line AA of FIG. 3, showing a switching state between the hot water supply and heating water during heating of the present invention, and FIG. 5 is a cross-sectional view taken along the line BB of FIG. FIG. 6 is a cross-sectional view taken along line CC of FIG. 3 to show an operating relationship between the first heating tube and the heat exchange means, and FIG. 7 is a cross-sectional view taken along line DD of FIG. The operating relationship between the valve and the heat exchange means is shown.

In the basic heating operation of the present invention according to the drawings, the heating water heated at the high temperature in the main heat exchanger 100 allows a predetermined heating circulation in a state in which a pipe inlet of the ondol or radietta and the first heating pipe connector 402 are connected. After the heating circulation, the heated water has a circulating process that flows out of the second heating pipe connector 404 through the return pipe 370 and back into the main heat exchanger 100.

That is, the heating water discharged from the main heat exchanger 100 is connected to the multi-layer heating layers 220 as shown by the white arrow of FIG. 4A and moves toward the heating outlet 248.

Subsequently, the heating water is continuously supplied through the heating pipe 350 of FIG. 3 connected to the outside through the heating inlet 353 of the second heating pipe 350. Thereafter, the heated heating water is returned through the heating water inlet 371 of the return pipe 370 and enters the main heat exchanger 100 to be recycled.

In the meantime, the hot water supply water is supplied in a cold water state through the second hot water supply pipe 340 as shown by the black arrow shown in FIG. 7 to a predetermined temperature in a state of supplying water to the multilayer hot water supply layer 230 of the heat exchange means 200. Preheated

The hot water supply of the preheated hot water is made at the moment when the hot water is started in the bathroom during the dissolution process.

That is, the hot water of the cold water flows into the second hot water pipe 340 through the second hot water pipe connecting portion 403 from the water pipe, and is supplied to the plurality of hot water layers 230 in the heat exchanger 200 to supply a plurality of heating layers ( Heat exchange is performed in a state of being treated with 220).

As shown in FIG. 4A, the hot water supply of the hot water in the preheating state is followed by the switching of the ball valve 362 as shown in FIG. 4B, and the hot water supply of the hot water supply layer 230 in the heat exchange means 200 through the first hot water pipe 330. The water is discharged and cold water is introduced through the second hot water pipe 340. The inflow of cold water is caused by the detection means 343 (low valve 344) provided in the second hot water pipe 340 operating the motor 321 of the valve driving means 320 while automatically detecting the cold water inflow. By switching the ball valve 362 (see FIG. 7 attached).

As the ball valve 362 is switched from the state of FIG. 4A to the state of FIG. 4B, the heating outlet 352 and the heating inlet 353 of the second heating pipe 350 are blocked, and the heating water is maintained through the return hole. The hot water is circulated to the heat exchanger and the water is continuously heated by the heating water and is discharged from the first hot water pipe 330 to each kitchen or bathroom through the first hot water pipe connector 401.

On the other hand, the present invention is opened and closed by the heating water pressure between the valve box 361 and the heating water return pipe 370 of the switching valve 360 as shown in Figure 2, 8a and 8b of the accompanying drawings Bypass means 380 is provided.

The bypass means 380 maintains a valve seat 385 formed in the valve box 361, a valve 381 for opening and closing one valve seat 385, and the valve 381 with a predetermined elasticity. It consists of an elastic body 383 and a support member 384 for guiding the elastic body 383 and the valve 381 while being welded from the outside through the support hole 386 formed in the return pipe 370.

The operation of the bypass means 380 having such a configuration does not take the reverse flow pressure of the heating water in the valve box 361 when the initial heating water is circulated normally as shown in FIG. 8A. However, as shown in FIG. 8B, when the heating water flows back in the valve box 361, the valve 381 is opened by a predetermined water pressure applied to the heating water to drain backflow heating water to the return pipe 370.

In other words, when the heating water normally circulated through the heating tube blocks the opening degree of the heating tube through the temperature control valve (not shown) installed in the heating tube, or controls the opening degree, a rapid reverse water pressure is generated on the inflow path side of the heating tube. The valve 381 is automatically developed by the water pressure of the backwashed heating water in the valve chamber 363 so as to bypass the backwashed heating water in the valve chamber 363, and thus a valve for a complicated pipeline or a bypass valve as in the related art. And a facility for connecting it with the temperature detection means becomes unnecessary.

The overall schematic operation of the present invention made as described above will be described with reference to the entire schematic diagram of the hot water supply apparatus of FIG. 9.

The main heat exchanger 100 burns gas or petroleum to heat the water circulating in the water pipe, and the radiator is heated by circulating the heated water, that is, the heating water in a pipe for heating. During heating, some of the heating water of the present invention is circulated while preheating the unused hot water.

The heating water obtained from the main heat exchanger is heated by repeating the above circulation, while the hot water is maintained at a high temperature while the hot water is preheated to a predetermined temperature even when the hot water is used in the bathroom or kitchen. The number is withdrawn.

On the other hand, the present invention improves the complicated structure made through many pipelines and connecting means as shown in FIG. 9 and compared with FIG.

That is, conventionally, as shown in Fig. 10, the heating water outlet pipe of the main heat exchanger, the heating pipe, and the inlet of the auxiliary heat exchange means are connected in a pipe state in three directions, and the auxiliary heat exchange means is again heated water after the heat exchange. It consists of a complex pipeline that must be equipped with a plurality of pipes for outflow, the hot water inflow pipe, and the heat exchange water pipes for outflow of hot water, and the installation process is complicated as well. .

However, the present invention has the simplicity of simply connecting to the main heat exchanger and heating tube and hot water supply pipe in the field in the state where the present invention was made before construction by applying the disassembled parts as shown in FIG. In addition, the size of the heat exchanger is significantly reduced to reduce the installation space, easy disassembly and assembly, there is an advantage that the repair and repair is convenient.

As such, in the past, since some of the heating water is not supplied to the heat exchange means during the heating, the cold water for hot water supply is kept in a cold water state that is not preheated. There was a problem in that the hot water supply water in the hot water state heat exchanged with the heating water only after the predetermined amount is discharged, but the present invention is improved by the problem of the conventional boiler hot water supply equipment, and the heating water is circulated and used during heating. By bypassing some of the heating water to preheat the hot water supply, the hot water is immediately released when using the hot water in the bathroom.

In addition, the present invention construction by the number of parts, such as a number of pipelines and connecting means as in the conventional structure by simply gathering a multi-functional hot water supply system by heat exchange with the heating water for the hot water as described above in one module It has the effect of providing an assembly structure that simplifies the complexity of the structure, and the simplification of the structure eventually reduces the manufacturing cost, the construction period, the process is short, the failure rate due to leakage, and the installation space is also reduced The side effects of the back are also considerable.
