Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings 1 to 10 as follows.

Fig. 1 is a direct-run flow schematic diagram with a typical compound watering system applied to a boiler.

Referring to Fig. 1, the operation of the complex direct water supply device applied to the boiler will be described as an example. However, it may vary depending on the type of boiler and its control and operation method. The following operation is an example for explaining the complex direct water supply device 200 according to the present invention.

When the operation of the boiler 100 is in the hot water mode, when the valve is opened to use the hot water, the flow of water flows along the external direct water supply line L1, and the flow switch senses the flow of the direct water, Water heat exchanger 104) and displays an operating state on an operation unit (not shown).

The water valve 105 allows the water to flow only through the direct water supply pipe 106 without opening the valve under the condition that the heating water shortage signal is not transmitted. When the water level in the cistern 103 storing the heating circulation water is lowered due to evaporation or the like and a heating water shortage signal is inputted to the control unit, the valve of the water valve 105 is opened to automatically replenish the direct water Automatic supply of direct water to supplement the heating water. In the boiler, the direct water complex water supply device enables the supply of direct water and the supply of water according to the supplement of heating water in a single body installed with the direct water supply line (L1) to be selectively and complexly supplied. Here, reference numeral 101 denotes a heat exchanger, 102 denotes a burner, L2 denotes a hot water supply line, and L3 denotes a heating water supply line.

2 is a body 210a of the existing direct water complex water supply apparatus 200a installed in the water supply line L1. Referring to FIG. 2, the direct water supplied through the pipe connection port 220a passes through the filter unit 300a, thereby changing the flow direction. As a result, the flow of the direct water flows in the acute direction indicated by the arrows fw1 ↑, fw2↙, and fw3 ↑, and the flow resistance is much larger than that when the flow resistance is not. This makes it difficult to react the flow switch 260a at a low pressure and a low flow rate. In addition, since the entire structure of the body 201a is located at an acute angle with the filter, the volume becomes large and the space for installing the boiler body becomes large, and the assembling direction of the filter is restricted.

Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. 3 to 10. FIG.

3 and 4 show a boiler's direct water complex water supply system 200 and its body 210 according to an embodiment of the present invention. Referring to FIGS. 3 and 4, it can be seen that the external shape is simpler and structurally simpler than the body structure and the shape of FIG. 2, which are referred to as existing direct mixed water supply devices.

The present invention is a direct water complex water supply device (200) of a boiler installed in a direct water supply line (L1) of a boiler (100) to connect and control direct water supplied from outside.

5 and 6 show a filter unit mounted on a body according to an embodiment of the present invention. FIG. 7 is an illustration showing the direct flow of the water in the direct water complex water supply device according to the embodiment of the present invention.

The body 210 of the direct water complex water supply device 200 according to the embodiment of the present invention may be configured as follows.

And a pipe connection port 220 connected to the direct water supply line L1. The pipe connection port 220 is directly connected to the direct water supply line L1 to introduce direct water.

And a flow path 230 for guiding the direct water introduced through the pipe connection port 220 to the filter unit 300. The flow path 230 is in communication with the piping connection port 220 as shown in FIG. 3, and is preferably perpendicular to the flow path of the piping connection port 220. For example, when the flow path of the pipe connection port 220 is vertical, it is appropriate that the flow path 220 for guiding the direct water to the filter unit 300 is placed in the horizontal direction.

Since the flow of water exhibits fw1 ↑, fw2↙, and fw3 ↑ (see FIG. 2) when the opening direction of the flow path leading the direct water to the filter unit is an acute angle, the flow resistance of the water is Is larger than the case of the flow paths fw1 ↑, fw2 ←, fw3 ↑ (see FIG. The flow path having acute angular orientation under the same conditions may have a longer total length than the flow path orthogonal to the vertical and horizontal directions. Therefore, the horizontal flow channel 230 that directs the direct water to the filter unit 300 while being orthogonal to the opening channel of the pipe connection port 220 has relatively low flow resistance of water compared to the acute angle open channel (FIGS. 7 and 8).

And a filter housing 240 for accommodating a filter unit 300 for purifying the water flowing along the flow path 230. As shown in FIGS. 3 and 4, the filter housing 240 is a vertical position orthogonal to the horizontal flow path 230. When the position of the filter unit relative to the flow path formed to be in communication with the piping connection port 220 is in the acute angle direction, the flow resistance of the water is large, so that the purifying action of the water by the filter unit under low pressure and low flow rate conditions may be insufficient. The filter housing 240, which is placed at a vertical position orthogonal to the filter housing 230, can receive the direct water supplied via the horizontal flow passage 230, thereby accommodating the filter unit 300 at a low pressure low flow rate condition The refining action can be made faster than the filter placed in the acute angle direction.

And includes a vertical flow passage 250 extending in the vertical direction from the filter housing 240 as shown in FIG. The vertical flow path 250 guides the direct water passing through the filter 311 of the filter unit 310 to the flow switch 260, the water side connection part 280, the direct water supply part 290 and the like. The filter 311 may be a mesh type of screen and other alternatives may be used. The filter 311 shown in the figure is an example of a mesh type.

And a flow switch assembly 270 for guiding the assembly of the flow switch 260 to control the flow of water flowing along the vertical flow path 250. Herein, the flow switch 260 can be used as various display information including information on the opening and closing of the hydraulic valve by inputting a switching signal as an electrical signal to the controller, and its specific configuration and operation are well known. .

The boiler's direct water complex water supply device and its body according to the embodiment of the present invention may include the following configuration.

It is preferable that the flow path 230 between the pipe connection port 220 and the filter unit 300 be provided with a horizontal flow path 230 that is positioned in a horizontal direction with respect to the filter unit 300. 4 and 7, the horizontal flow path 230 is specifically shown. This serves to shorten the length of the oil passage as compared with the acute angle oil passage and to direct the supplied direct water to the filter unit 300 as described above, and exhibits a low oil passage resistance.

The space 241 of the filter housing 240 may include a space reducing portion 242 for narrowing the cross section of the flow passage 250 relative to the housing space 241. The space reducing portion 242 is formed by artificially reducing the space volume as compared with the space 241 of the filter housing 240 as shown in FIGS. A vertical channel 250 is formed on the basis of the center of the space 241 and a vertical channel 250 is formed on the center of the vertical channel 250, It is preferable that the space narrowing portion 242 that reduces the space 241 of the filter housing 240 exhibits a shape whose width is narrowed. Since the water can be collected through the filter 311 and the flow rate can be expected to increase compared to the flow rate, the filtering efficiency by the flow velocity can be expected.

For example, the space reducing portion 242 may be formed in a cone shape having no sharp end, and the filter 311 may be formed in a dome shape, for example, and the filter unit 300 may be seated along the filter housing 240 The filter 311 can be accurately mounted on the space reducing portion 242, so that the stable mounting state can be maintained for a long period of time without causing problems such as separation, lifting and dropping of the filter.

5, the filter unit 300 includes a filter unit 310 having a plurality of openings 314 that are seated in the space 241 of the filter housing 240 to guide the inflow of water, And a knob unit 320 that is detachably coupled to the body 210. The filter unit 300 may be combined with the filter unit 300 as shown in FIG.

The filter 310 includes a body 312 coupled along the knob 320 and at least one or more supporters 314 extending from the body 312 and defining an opening 314 at an upper portion of the body 312 313, and a filter 311 supported by the supporter 313. The knob 320 includes a body 321 that is disassembled and coupled to the body 312 of the filter unit 310, a knob 322 for rotating the body 321, and a knob 322, And decomposing and coupling means 323 for inducing disassembly and coupling with the body 321 of the unit 310.

5 and 6, the body 312 of the filter portion 310 is assembled along the upper portion of the knob portion 320 and along the disassembly means 323. The decomposing and coupling means 323 may be formed as a slide step at a part of the side wall surface of the upper portion of the knob portion 320 and may have a knob portion 323 formed at the lower end inner wall surface of the body 312 of the filter portion 310, When the protruding stopper stuck to the slide step of the part 320 is provided, if the knob 322 rotates in the normal and reverse directions, the stopper protruding from the body of the filter part is separated from the slide step and disassembled. If the filter unit 300 is divided into a filter unit and a knob unit and disassembly is possible, the filter 311 can be checked, exchanged, and cleaned. Therefore, the filter unit has semi-permanent usability and the installation direction is also located on the same straight line with respect to the vertical flow path 250, so that the mounting and assembly properties can be improved.

In addition, the top surface shape of the filter 311 can be selected from a dome shape or a planar shape. When the dome-shaped filter is formed in a corresponding size that can be seated in the space reducing portion 242 formed in the space 241 of the filter housing 240 as shown in FIG. 7, It can be seated in a symmetrical structure facing the wall. If the rim 315 is placed on the filter 311, it can be brought into close contact with the inner wall of the space 241 of the filter housing to prevent the flow and prevent leakage, thereby maintaining a high level of purification for a long period of time.

8 is an illustration of the direct-to-water flow in a direct water complex watering device according to an embodiment of the present invention.

As shown in FIG. 8, the flow direction of the direct water supplied along the pipe connection port of the body is constant at fw1, fw2, and fw3. Therefore, direct flow always shows vertical, horizontal and vertical directions. This means that relative to the position of the filter unit, the position and direction of the flow path represent the slave flow, it is possible to reduce the flow path resistance relatively at the same pressure and flow rate operating condition as the flow path at the acute angle direction, Direct effect. Finally, it affects the performance and reliability of the direct water complex water supply system.

9 is an exemplary view of a filter unit according to another embodiment of the present invention. The filter unit 300a may include that the upper surface of the filter 311a is flat as shown in Fig. The body 312a of the filter portion 310a can be combined along the upper portion of the knob portion 320a and the disassembly means. The filter 310a includes a body 312a coupled to the knob 320a and at least one supporter 313a extending from the body 312a and forming an opening 314a at an upper portion of the body 312a. And a filter 311a supported by the supporter 313a. The knob portion 320a includes a body 321a which is disassembled and coupled to the body 312a of the filter portion 310a, a knob 322a for rotating the body 321a, and a knob 322a, And decomposing and coupling means for inducing disassembly and coupling with the body 321a of the portion 310a.

The decomposing and coupling means can be easily applied by those skilled in the art as described in the example of the filter unit 300 in which the filter is dome-shaped, although not specifically shown in the drawings. If the filter unit 300a is divided into the filter unit 300 and the knob unit 300 and the disassembly unit 300 is disassembled, the filter 311a can be inspected, exchanged, and cleaned. Therefore, the filter unit 300a has semi-permanent usability and installation direction is also located on the same straight line with respect to the vertical flow path 250, so that the mounting and assembly performance can be improved.

When the vertical wall surface of the filter 311a is formed of the threaded portion 316a, the inner wall of the space 241 of the filter housing is also threaded (not shown) to induce thread engagement to prevent the filter unit 300a from flowing The high level of refining can be sustained for a long time by blocking leakage.

According to the embodiment of the present invention, when the filter unit 300 (300a) is mounted on the body 210, the filter housing 240 provided on the body 210 directly without using any adapter or joint member And is mounted as a receiving type. It is structurally uncomplicated and reduces the number of components.
