Description

[Technical field]

[0001] The present invention relates to a heating-enabled hot water mat, and more particularly to an assembly-type hot water mat that is expandable by assembly and has parallel flows.

[0002] This application claims priority to 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, the entire contents of which are incorporated herein by reference in their entirety in the specification and drawings. [Background technology]

[0003] Ondol is a traditional Korean heating method that involves heating the floor through pipes installed under the floor, through which hot water circulates to heat the floor.

[0004] Not only does the initial construction of such an ondol require a lot of money, but it can also cost even more to set up the ondol after the floor construction is completed. Therefore, in order to use ondol at a low cost, hot water mats have been produced and are on the market.

[0005] Conventional hot water mats such as those in Patent Document 1 (Korea Patent Publication No. 2014-0049395) are sold in the form of a bed matrix or futon, and have the disadvantage that they can only be used in small spaces. In addition, conventional hot water mats operate independently of each other, making it difficult to expand the space (i.e., expand the ondol area).

[0006] In order to solve such problems of the conventional technology, a prefabricated hot water mat has been proposed, which allows the optimum combination of patterns according to the space by assembling various types of heating panels.

[0007] Patent Document 2 (JP Patent Publication 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. In addition, 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 panels of FIG. 1 having a plurality of basic patterns, an assembly type heating panel as shown in FIG. 2 can be completed. That is, a total of nine heating panels consisting of three first pattern P1, two second pattern P2, one third pattern P3, and three fourth pattern P4 are combined.

[0008] Meanwhile, referring to FIG. 3, Patent Document 3 (US2011 / 0073274A1) discloses an assembly type heating panel in which three panels are assembled to provide heat by hot water over a wide area.

[0009] In addition, Patent Document 4 (Korean Patent Publication No. 10-2046630) filed and registered according to the present invention discloses hot water mats assembled in a 3×4 arrangement as shown in FIG. 4. Referring to FIG. 4, a total of 12 prefabricated hot water mats are assembled by a plurality of expansion connectors. Thus, hot water supplied from the hot water boiler 10 flows through the main pipe of the first prefabricated hot water mat 100, the third bypass pipe and main pipe of the second prefabricated hot water mat 200, the third bypass pipe and main pipe of the third prefabricated hot water mat 300, the third bypass pipe, main pipe and branch pipe of the fourth prefabricated hot water mat 400, the main pipe, first bypass pipe and branch pipe of the eighth prefabricated hot water mat 800, the main pipe and first bypass pipe of the twelfth prefabricated hot water mat 1200, the main pipe of the eleventh prefabricated hot water mat 1100, the branch pipe of the seventh prefabricated hot water mat 700, and the main pipe of the seventh prefabricated hot water mat 700. The water circulates through the first bypass pipe, the main pipe and the second bypass pipe, the second bypass pipe of the 11th prefabricated hot water mat 1100, the main pipe of the 10th prefabricated hot water mat 1000, the branch pipe of the 6th prefabricated hot water mat 600, the first bypass pipe, the main pipe and the second bypass pipe, the second bypass pipe of the 10th prefabricated hot water mat 1000, the main pipe of the 9th prefabricated hot water mat 900, the branch pipe of the 5th prefabricated hot water mat 500, the first bypass pipe and the main pipe, and the second bypass pipe of the first prefabricated hot water mat 100, and is further combined into the hot water boiler 10.

[0010] [Patent Document 1] Korean Patent Publication No. 2014-0049395 [Patent Document 2] JP 2002-228170 A [Patent Document 3] US Patent Application Publication No. 2011 / 0073274 [Patent Document 4] Korean Patent No. 10-2046630 Summary of the Invention [Problem to be solved by the invention]

[0011] The prefabricated hot water mats of Patent Documents 2 to 4 are all characterized by having a serial flow in which hot water discharged from a hot water boiler circulates through multiple hot water mats in sequence before returning to and flowing into the hot water boiler.

[0012] This not only results in a long time being required for hot water to be supplied to all the hot water mats, but also causes the temperature of the final hot water returning to the hot water boiler to be lower, resulting in a problem of reduced energy efficiency.

[0013] On the other hand, Patent Document 2 in Figure 1 requires that one hot water mat include a minimum of eight inlet / outlet connectors and four interchangeable connectors, Patent Document 3 in Figure 3 requires that one hot water mat include a minimum of eight female connectors and male connectors, and Patent Document 4 in Figure 4 requires that one hot water mat include eight on-off valves and six bypass valves.

[0014] As described above, the conventional assembled hot water mats with serial flow as disclosed in Patent Documents 2 to 4 require the installation of multiple valves, connectors, quick disconnect couplings, etc. in order to create a serial hot water flow using multiple hot water mats, which results in an increase in the overall cost of the hot water mats.

[0015] In addition, in order to change the serial flow of the conventional assembled hot water mat to a parallel flow, it is necessary to develop a hot water boiler with enough power to pump and circulate hot water to multiple hot water mats at the same time. However, in this case, as the power of the hot water boiler increases, side effects such as noise and reduced energy efficiency are encountered.

[0016] Therefore, the first technical objective of the present invention is to provide an assembly-type hot water mat with parallel hot water flows that has low noise and high energy efficiency.

[0017] A second technical objective of the present invention is to provide an assembly-type hot water mat with parallel hot water flow, which can minimize the cost by improving the hot water flow path of the unit hot water mat, without additionally increasing the power of the hot water boiler, and by minimizing the number of valves and connectors to be installed.

[0043] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will now be described with reference to the accompanying drawings, which are not drawn to scale and in which like reference numerals in different drawings refer to like elements.

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

[0045] 5, the prefabricated hot water mat with parallel flow according to an embodiment of the present invention is constructed by assembling two unit hot water mats together. First, the basic structure of the unit hot water mat according to an embodiment of the present invention will be described based on the unit hot water mat P1100 of the two unit hot water mats P1100 and P2100'. At this time, the remaining unit hot water mat P2100' has the same structure as the unit hot water mat P1100 in a symmetrical manner.

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

[0047] The unit hot water mat P1100 preferably has a rectangular shape and includes a plurality of on / off valves 161-168 formed in pairs on each of four sides, a heating pipe 130 formed in a certain pattern (e.g., a zigzag pattern) to pass hot water flowing in from a hot water boiler 200 in a certain pattern to heat the surface of the hot water mat, a first main pipe 110 for allowing the hot water flowing in from the hot water boiler 200 to flow in a first direction (e.g., a long side direction or a longitudinal direction) of the rectangular mat, a second main pipe 115 for allowing the hot water in the first direction to flow in a second direction (e.g., a short side direction or a width direction) of the rectangular mat, and a heating pipe 130 for allowing the hot water flowing in from the hot water boiler 200 to flow in a second direction (e.g., a short side direction or a width direction) of the rectangular mat. the first main pipe 110 and the second main pipe 115 in the first direction to connect in series at least two or more unit hot water mat heating pipes 130 adjacent to each other in the first direction; a bypass pipe 120 for switching the hot water in the first direction of the first main pipe 110 to hot water in the second direction of the second main pipe 115 by connecting between the first main pipe 110 and the second connecting pipe 145, and transmitting 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 to the heating pipe 130; 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 “start 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 start 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, 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 in parallel through the heating pipes of a plurality of unit hot water mats directly or indirectly connected to the starting unit hot water mat, and then is collected into the return pipe 118 of the starting unit hot water mat and returns to the hot water boiler 200 through the first connecting pipe 142.

[0050] The hot water introduced from the hot water boiler 200 flows in a first direction through the first main pipe 110, then changes direction through the bypass pipe 150, and forms a serial flow in a second direction through the second main pipe 115. In this manner, the hot water that reaches the second main pipe 115 is divided into at least two or more hot water streams in the second main pipe 115, and then is branched into a plurality of streams.

[0051] In the present invention, when a plurality of unit hot water mats are assembled to form an assembled hot water mat in an N×M array (a matrix of N rows and M columns) (where N and M are natural numbers greater than or equal to 1), the first main pipes of the unit hot water mats constituting one column are connected in series to form a main flow in a first direction, and the second main pipes of the unit hot water mats constituting one row are connected in series to form a main flow in a second direction. Then, the main flow in the second direction is branched into a plurality of parallel flow paths to form a plurality of branch flows.

[0052] The on-off valves 161-168 are valves that normally close the flow paths to an off state, and open the flow paths to an on state when the adjacent on-off valves 161-168 are connected to each other. The on-off valves 161-168 are 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 end of the first connecting pipe 142 and the second connecting pipe 145.

[0053] Therefore, when the unit hot water mat 100 is connected alone to the hot water boiler (BLR) 200, all of the on-off valves 161-168, except for the on-off valves 161, 162 installed on 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 connection connector 150 is provided on the bypass pipe 120 to open or close the hot water flow path of the bypass pipe 120. When the coupling of the connection connector 150 is in an off state, the bypass pipe 120 maintains its flow path in a closed state. That is, since the connection connectors 150 are not coupled to each other in a normal state, the hot water flow path of the bypass pipe 120 is blocked and closed. Meanwhile, the flow path of the bypass pipe 120 is opened by coupling the connection connectors 150 to each other. Thus, 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 connection connector 150 is in an off state, the flow paths of the first main pipe 110 and the second main pipe 115 are not connected to each other.

[0055] In the present invention, when a plurality of unit hot water mats are assembled to form a prefabricated hot water mat in an N×M array (a matrix of N rows and M columns) (where N and M are natural numbers equal to or greater than 1), only the coupling connectors 150 of the unit hot water mats in row 1 and column 1 are turned on, and the coupling connectors 150 of the remaining unit hot water mats are all turned off. That is, only the first main pipe 110 and the second main pipe 115 of the unit hot water mats in row 1 and column 1 are connected, and the first main pipe 110 and the second main pipe 115 of all the remaining unit hot water mats are not connected to each other. As a result, the hot water flows of the first main pipes connected in series of the unit hot water mats constituting one row form a serial flow in the first direction, and the hot water flows of the second main pipes connected in series of the unit hot water mats constituting one row form a serial flow in the second direction. The serial hot water flow in the first direction is switched to the serial hot water flow in the second direction by the bypass pipes of the unit hot water mats arranged in one row and one column, and the serial hot water flow in the second direction thus switched branches off from the points where it is connected to each heating pipe of the unit hot water mats constituting the row, forming a plurality of parallel hot water flows.

[0056] The heating pipe 130 may be formed in various patterns in 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 preferably has a pattern that can increase the heating efficiency per unit area. The pattern of the heating pipe 130 may be various, such as a zigzag pattern, a spiral pattern, etc. It is most preferable to apply a zigzag pattern as shown in FIG. 5 as the pattern of the heating pipe 130 for smooth flow of hot water and heating efficiency.

[0057] The parallel hot water flow according to the present invention is configured such that a plurality of branch hot water flow paths are connected in parallel to one main hot water flow path. For example, Fig. 6 shows a parallel hot water flow in which two branch hot water flow paths are connected in parallel to one main hot water flow path in the second direction, and Fig. 7 shows a parallel hot water flow in which five branch hot water flow paths are connected in parallel to one main hot water flow path in the second direction. In both Figs. 6 and 7, heating pipes of three unit hot water mats are connected in series to each branch hot water flow path 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 array (a matrix of three rows and two columns), and the series flow where the heating pipes of the three unit hot water mats are connected is branched into two parallel flows to form a 3×2 parallel hot water flow. In the case of FIG. 7, a total of 15 unit hot water mats P1 to P 15 These are assembled in a 3x5 array (a matrix of 3 rows and 5 columns) and the serial flow where the heating pipes of the three unit hot water mats are connected is branched into five parallel flows to form a 3x5 parallel hot water flow.

[0059] In this case, in the M×N matrix (a matrix of N rows and M columns) (where N and M are natural numbers equal to or greater than 1) constituting the prefabricated hot water mat, the first main pipe of the unit hot water mat constituting one column and the second main pipe of the unit hot water mat constituting one row are connected by the bypass pipes of the unit hot water mats arranged in one row and one column to form 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 constituting one column, the on-off valves 161 and 165 provided on the first main pipe 110 are connected to each other to open the serial main hot water flow path in the first direction. Also, in order to connect the second main pipes of the unit hot water mats constituting one row, the on-off valves 164 and 167 provided on the second main pipe 115 are connected to each other to open the serial main hot water flow path in the second direction. Then, in order to connect the return pipes of the unit hot water mats constituting M rows, the on / off valves 163, 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 connecting connectors provided on the bypass pipes of the unit hot water mats in one row and one column are coupled to open the hot water flow path of the bypass pipe.

[0060] First, referring to FIG. 5, parallel hot water flows when 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 on the first main pipe 110 directly connected to the hot water boiler 200 and the first connecting pipe 142 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', and 168' are maintained in the off state. The connectors 150 of the unit hot water mats P1100 are coupled together to open the hot water flow path of the bypass pipe 120, and the connectors 150' of the unit hot water mats P2100' are not coupled together to close the hot water flow path of the bypass pipe 120'.
