Description

Technical Field

[0001] The present invention relates to a warm water mat capable of heating, and more particularly, to a prefabricated warm water mat that can be expanded by assembly and has a parallel flow.

[0002] This application claims priority based on Korean Patent Application No. 10-2022-0175899 filed on December 15, 2022 and Korean Patent Application No. 10-2023-0026549 filed on February 28, 2023, and all of the contents disclosed in the specifications and drawings of the said applications are incorporated into this application.

Background Art

[0003] Ondol is a traditional Korean heating method for warming the floor, in which pipes are installed under the floor, and warm water circulates through these pipes to heat the floor.

[0004] Such ondol not only requires a lot of cost for initial construction, but particularly, even more cost may be incurred to install ondol in a place where floor construction has been completed. Therefore, in order to use ondol at a low cost, warm water mats have been produced and marketed.

[0005] Conventional warm water mats such as Patent Document 1 (Korean Patent Publication No. 2014-0049395) are sold in the form of a bed matrix or a futon, and have the disadvantage of being usable only in a narrow space. In addition, conventional warm water mats operate independently of each other, and there is also a problem that it is not easy to expand the space (that is, expand the ondol area).

[0006] In order to solve the problems of such conventional technologies, a prefabricated warm water mat has been proposed that can combine an optimal pattern according to the space by assembling various types of heating panels.

[0007] Patent Document 2 (Japanese Unexamined Patent Application Publication No. 2002-228170) discloses a heating panel that can be used as a floor heating panel by combining and laying a plurality of panels P. Referring to FIG. 1, the panel P is square or rectangular. A pair or a plurality of pairs of input / output connectors 1 are provided on the four sides of the panel P so that hot water flows into or out of the panel from each of the four sides. Further, a plurality of change connectors 2 are arranged inside the panel P so that the direction of the heat dissipation pipe 3 connected to each input / output connector 1 can be changed inside the panel P. Therefore, by assembling a plurality of the panels of FIG. 1 having a plurality of basic patterns, an assembled heating panel as shown in FIG. 2 can be completed. That is, a total of nine heating panels composed of three first pattern P1s, two second pattern P2s, one third pattern P3, and three fourth pattern P4s are combined.

[0008] On the other hand, referring to FIG. 3, Patent Document 3 (US2011 / 0073274A1) discloses an assembled heating panel that assembles three panels to perform heating with hot water over a large area.

[0009] In addition, Patent Document 4 (Korean Registered Patent Publication No. 10-2046630) filed and registered according to the present invention discloses a warm water mat assembled in a 3×4 array form as shown in FIG. 4. Referring to FIG. 4, a total of 12 assembled warm water mats are assembled by a plurality of extension connectors. Therefore, the warm water supplied from the hot water boiler 10 circulates through the main pipe of the first assembled warm water mat 100, the third bypass pipe and the main pipe of the second assembled warm water mat 200, the third bypass pipe and the main pipe of the third assembled mat 300, the third bypass pipe of the fourth assembled warm water mat 400, the main pipe and the branch pipe, the main pipe of the eighth assembled warm water mat 800, the first bypass pipe and the branch pipe, the main pipe and the first bypass pipe of the twelfth assembled warm water mat 1200, the main pipe of the eleventh assembled warm water mat 1100, the branch pipe of the seventh assembled warm water mat 700, the first bypass pipe, the main pipe and the second bypass pipe, the second bypass pipe of the eleventh assembled warm water mat 1100, the main pipe of the tenth assembled warm water mat 1000, the branch pipe of the sixth assembled warm water mat 600, the first bypass pipe, the main pipe and the second bypass pipe, the second bypass pipe of the tenth assembled warm water mat 1000, the main pipe of the ninth assembled warm water mat 900, the branch pipe of the fifth assembled warm water mat 500, the first bypass pipe and the main pipe, and the second bypass pipe of the first assembled warm water mat 100, and is further collected into the hot water boiler 10.

Summary of the Invention

Problems to be Solved by the Invention

[0011] Each of the assembled hot water mats of Patent Documents 2 to 4 is characterized in that the hot water discharged from the hot water boiler has a series flow in which it circulates through a plurality of hot water mats in order and then returns to the hot water boiler and flows in.

[0012] This has the problem that not only does it take a long time for hot water to be supplied to all the hot water mats, but the temperature of the last hot water returning to the hot water boiler becomes low, resulting in a decrease in energy efficiency.

[0013] On the other hand, Patent Document 2 in FIG. 1 needs to include at least 8 input / output connectors and 4 change connectors in one hot water mat, Patent Document 3 in FIG. 3 needs to include at least 8 female connectors and male connectors in one hot water mat, and Patent Document 4 in FIG. 4 needs to include 8 on-off valves and 6 bypass valves.

[0014] Thus, in order to create a series hot water flow using a plurality of assembled hot water mats having a conventional series flow in Patent Documents 2 to 4, a plurality of valves, connectors, quick disconnect couplings, etc. need to be attached, which has caused an increase in the overall cost of the hot water mat.

[0015] In addition, in order to switch the series flow of such a conventional assembled hot water mat to a parallel flow, it is necessary to develop a hot water boiler having a power sufficient to pump and circulate hot water to a plurality of hot water mats simultaneously. However, in this case, as the power of the hot water boiler increases, new problems such as a decrease in energy efficiency along with side effects such as noise will be faced.

[0016] Therefore, a first technical problem of the present invention is to provide an assembled hot water mat with a parallel hot water flow having low noise and high energy efficiency.

[0017] In addition, the present invention aims to provide an assembled hot water mat with parallel hot water flow that can minimize costs by improving the hot water flow path of the unit hot water mat without additionally increasing the power of the hot water boiler and minimizing the number of valves and connectors to be installed, which is the second technical problem.

[0018] Other objects and advantages of the present invention can be understood from the following description and will be more clearly understood by the embodiments of the present invention. Also, the objects and advantages of the present invention can be achieved by the means and combinations thereof shown in the claims.

[0029] As the eleventh aspect of the present invention, an assembled hot water mat having a parallel flow has at least two or more unit hot water mats of any one of the fifth to tenth aspects assembled to form an M×N matrix (M and N are natural numbers of 1 or more). By connecting the on-off valves provided at both ends of the first main pipe of the unit hot water mats constituting one column of the M×N matrix to each other, a main hot water flow path in the first direction is formed. The on-off valve provided at one end of the first main pipe of the unit hot water mat in the first row and M columns is connected to the hot water boiler.

The drawings disclosed below are presented as examples for conveying the idea of the present invention to those skilled in the art. Therefore, the present invention is not limited to the drawings shown below and can be embodied in other forms. Also, throughout the specification, the same reference numerals indicate the same components. Note that in the drawings, the same components are denoted by the same reference numerals in all the drawings as much as possible.

[0043] Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and the same reference numerals in each drawing indicate the same components.

[0044] FIG. 5 is a schematic plan view of an assembled hot water mat having a parallel flow according to a preferred embodiment of the present invention in which two unit hot water mats 100 and 100' are joined.

[0045] Referring to FIG. 5, an assembled hot water mat having a parallel flow according to an embodiment of the present invention is configured by assembling two unit hot water mats with each other. First, the basic configuration of a unit hot water mat according to an embodiment of the present invention will be described with reference to the unit hot water mat P1100 among the two unit hot water mats P1100 and P2100'. At this time, the remaining unit hot water mat P2100' also has the same configuration symmetrically to the unit hot water mat P1100.

[0046] In the present invention, the term "unit hot water mat" means one hot water mat before being assembled, such as the reference numerals 100 or 100' in FIG. 5, and the term "assembled hot water mat" means a hot water mat in a state where two or more of the unit hot water mats are assembled as shown in FIGS. 5 to 7.

[0047] The unit hot water mat P1100 preferably has a rectangular form, and includes a plurality of on-off valves 161 to 168 formed in pairs, two on each of the four sides, a heating pipe 130 formed in a certain pattern (for example, a zigzag pattern) to allow the hot water flowing in from the hot water boiler 200 to pass through in a certain pattern and heat the surface of the hot water mat, a first main pipe 110 to allow the hot water flowing in from the hot water boiler 200 to flow in the first direction (for example, the long side direction or the longitudinal direction) of the rectangular mat, a second main pipe 115 to allow the hot water in the first direction to flow in the second direction (for example, the short side direction or the width direction) of the rectangular mat, a return pipe 118 to collectively return the hot water that has passed through the heating pipe 130 to the hot water boiler (BLR) 200 in the second direction, a first connection pipe 142 connected in the first direction to the return pipe 118 and a second connection pipe 145 connected in the first direction to the second main pipe 115 to serially connect between the heating pipes 130 of at least two or more unit hot water mats adjacent to each other in the first direction, a bypass pipe 120 to switch the hot water in the first direction of the first main pipe 110 to the hot water in the second direction of the second main pipe 115 and transmit it to the heating pipe 130 by connecting between the first main pipe 110 and the second connection pipe 145, and a connection connector 150 provided on the bypass pipe 120.

[0048] In the case of a unit hot water mat directly connected to the hot water boiler 200 (hereinafter abbreviated as "starting unit hot water mat"), the first connection pipe 142 connects between the return pipe 118 and the hot water boiler 200. Also, one end of the first main pipe 110 of the starting unit hot water mat is directly connected to the hot water boiler 200.

[0049] Therefore, in the case of the assembled hot water mat according to the present invention, the hot water from the hot water boiler 200 flows through the first main pipe 110, the bypass pipe 120, and the second main pipe 115 of the starting unit hot water mat, passes through the heating pipes of a plurality of unit hot water mats directly or indirectly connected to this starting unit hot water mat in parallel, and then is collected in the return pipe 118 of the starting unit hot water mat and returns to the hot water boiler 200 through the first connection pipe 142.

[0050] The hot water introduced from the hot water boiler 200 forms a series flow that flows in the first direction through the first main pipe 110, then switches direction through the bypass pipe 150 and flows in the second direction through the second main pipe 115. In this way, the hot water reaching the second main pipe 115 is divided into at least two or more hot water flows in the second main pipe 115 and then branches into a plurality.

[0051] In the present invention, if a plurality of unit hot water mats are assembled to form an assembled hot water mat in an N×M arrangement (a matrix of N rows and M columns) (where N and M are natural numbers of 1 or more), the first main pipes of the unit hot water mats constituting one column are connected in series with each other to form a main flow in the first direction, and the second main pipes of the unit hot water mats constituting one row are connected to each other to form a main flow in the second direction in series. Then, it branches from the main flow in the second direction into a plurality of parallel flow paths to form a plurality of branched flows.

[0052] The on-off valves 161 to 168 are valves that normally close the flow path in the off state and open the flow path in the on state when adjacent on-off valves 161 to 168 are connected to each other. The on-off valves 161 to 168 are respectively provided at both ends of the first main pipe 110, both ends of the second main pipe 115, both ends of the return pipe 118, and one-directional ends of the first connection pipe 142 and the second connection pipe 145.

[0053] Therefore, with the unit hot water mat 100 connected to the hot water boiler (BLR) 200 alone, all the on-off valves 163 to 168 among the on-off valves 161 to 168, except the on-off valves 161 and 162 provided in the first main pipe 110 and the first connecting pipe 142 directly connected to the hot water boiler 200, maintain the off state.

[0054] The connecting connector 150 is provided in the bypass pipe 120 to open or close the hot water flow path of the bypass pipe 120. If the coupling of the connecting connector 150 is in the off state, the bypass pipe 120 is maintained in a state where its flow path is closed. That is, in normal times, since the connecting connectors 150 are not coupled to each other, the hot water flow path of the bypass pipe 120 is blocked and closed. On the other hand, by coupling the connecting connectors 150 to each other, the flow path of the bypass pipe 120 is opened. As a result, the hot water flow in the first direction of the first main pipe 110 can be switched to the hot water flow in the second direction of the second main pipe 115 through the bypass pipe 120 and flow into the heating pipe 130. Thus, when the coupling of the connecting connector 150 is off, the flow paths of the first main pipe 110 and the second main pipe 115 are not connected.

[0055] In the present invention, if a plurality of unit hot water mats are assembled to form an assembled hot water mat in an N×M array (an N-row and M-column matrix) (where N and M are natural numbers of 1 or more), only the coupling connector 150 of the unit hot water mat in the first row and first column has its coupling turned on, and the coupling connectors 150 of the remaining unit hot water mats all have their couplings turned off. That is, only the first main pipe 110 and the second main pipe 115 of the unit hot water mat in the first row and first column are connected, and the first main pipes 110 and the second main pipes 115 of all the remaining unit hot water mats are not connected to each other. As a result, the hot water flow in the first main pipes connected in series of the unit hot water mats constituting one column forms a series flow in the first direction, and the hot water flow in the second main pipes connected in series of the unit hot water mats constituting one row forms a series flow in the second direction. Then, the series hot water flow in the first direction is switched to the series hot water flow in the second direction by the bypass pipe of the unit hot water mat in the first row and first column, and the series hot water flow in the second direction thus switched branches from the point where it is connected to each heating pipe of the unit hot water mats constituting the one row, forming a plurality of parallel hot water flows.

[0056] The heating pipe 130 can be formed in various patterns at the center of the unit hot water mat 100, which is the space between the second main pipe 115 and the return pipe 118. The heating pipe 130 forms a hot water flow path for heating the upper surface of the hot water mat, and desirably has a pattern that can enhance the thermal efficiency per unit area. Such patterns of the heating pipe 130 can be diverse, such as a zigzag pattern, a vortex pattern, etc. As the pattern of the heating pipe 130, it is most desirable to apply a zigzag pattern as shown in FIG. 5 for the smooth flow of hot water and the heating efficiency.

[0057] The parallel hot water flow according to the present invention forms a configuration in which a plurality of branched hot water flow paths are connected in parallel to one main hot water flow path. For example, in the case of FIG. 6, a parallel hot water flow in which two branched hot water flow paths are connected in parallel to one main hot water flow path in the second direction is shown. In the case of FIG. 7, a parallel hot water flow in which five branched hot water flow paths are connected in parallel to one main hot water flow path in the second direction is shown. Further, in both FIGS. 6 and 7, in each branched hot water flow path, the heating pipes of three unit hot water mats are connected in series in the first direction.

[0058] In the case of FIG. 6, a total of six unit hot water mats P1 to P6 are assembled in a 3×2 arrangement (a 3-row 2-column matrix), and the series flow in which the heating pipes of three unit hot water mats are connected is branched into two parallel flows to form a 3×2 parallel hot water flow. Further, in the case of FIG. 7, a total of fifteen unit hot water mats P1 to P 15 are assembled in a 3×5 arrangement (a 3-row 5-column matrix), and the series flow in which the heating pipes of three unit hot water mats are connected is branched into five parallel flows to form a 3×5 parallel hot water flow.

[0059] At this time, in the M×N matrix (matrix of N rows and M columns) (where N and M are natural numbers of 1 or more) that constitutes the assembled hot water mat, the first main pipe of the unit hot water mats that make up one column and the second main pipe of the unit hot water mats that make up one row are connected by the bypass pipe of the unit hot water mat arranged at the first row and first column, and constitute the main flow path of the parallel hot water flow. That is, in order to connect the first main pipes of the unit hot water mats that make up one column, the on-off valves 161 and 165 provided on the first main pipe 110 are connected to each other to open the series main hot water flow path in the first direction. Also, in order to connect the second main pipes of the unit hot water mats that make up one row, the on-off valves 164 and 167 provided on the second main pipe 115 are connected to each other to open the series main hot water flow path in the second direction. Then, in order to connect the return pipes of the unit hot water mats that make up M rows, the on-off valves 163 and 168 provided on the return pipe 115 are connected to each other to open the return hot water flow path in the second direction. Then, the connection connectors provided on the bypass pipe of the unit hot water mat at the first row and first column are coupled to open the hot water flow path of the bypass pipe.

[0060] First, with reference to FIG. 5, the parallel hot water flow in the case where two unit hot water mats P1100 and P2100' are assembled will be described. Among the on-off valves of the unit hot water mat P1100, the on-off valves 161 and 162 provided in the first main pipe 110 and the first connecting pipe 142 directly connected to the hot water boiler 200 are opened. Also, the on-off valves 167 and 164' are connected to each other to connect the second main pipes 115 and 115' of the unit hot water mats P1100 and P2100' to each other, thereby opening the main hot water flow path in the second direction. Also, the on-off valves 168 and 163' are connected to each other to connect the return pipes 118 and 118' of the unit hot water mats P1100 and P2100' to each other, thereby opening the return hot water flow path in the second direction. And the remaining on-off valves 163, 164, 165, 166, 161', 162', 165', 166', 167', 168' maintain the off state. Then, the connecting connectors 150 of the unit hot water mat P1100 are coupled to each other to open the hot water flow path of the bypass pipe 120, and the connecting connector 150' of the unit hot water mat P2100' is not coupled, so that the hot water flow path of the bypass pipe 120' is closed.

[0061] In such a state, when the hot water boiler 200 is operated, the hot water heated by the hot water boiler 200 reaches the second main pipe 115 through the first main pipe 110 and the bypass pipe 120 of the unit hot water mat P1100, and then branches into two hot water flow paths. One flows into the heating pipe 130 of the unit hot water mat P1100, and the other flows into the heating pipe 130' through the second main pipe 115' of the unit hot water mat P2100'.

[0062] The hot water flow paths branched into the heating pipes 130 and 130' of the unit hot water mats P1100 and P2100' are gathered into the return pipe 118 of the unit hot water mat P1100, and then further return to the hot water boiler 200 through the first connecting pipe 142.

[0063] As described above, the assembled hot water mat of FIG. 5 according to the present invention switches the hot water flowing in from the hot water boiler 200 in the first direction to the second direction, then divides it into two branched flow paths and makes it flow in the first direction according to a certain pattern, and then further combines it in the second direction and returns it to the hot water boiler 200, forming a parallel hot water flow that constitutes two branched hot water flow paths (each branched hot water flow path is composed of one heating pipe).
