Description

  The present invention relates to a hot water mat using hot water heated by a hot water boiler. More specifically, the hot water mat provided in the hot water mat can be prevented from being damaged by being folded, and can be easily folded and stored in multiple stages. The present invention relates to a multi-stage foldable hot water mat.

  Generally, a heating mat is used to locally heat or keep a floor of an indoor space, and an electric mat and a hot water mat are used.

  Conventionally, electric heating wires are arranged over the entire surface of the mat, and electric mats that use heat generated by electricity are mainly used, but because they use electricity, there is a high risk of fire or electric shock. There is a problem that electromagnetic waves that are harmful to the human body are emitted due to their own electrical characteristics.

  Therefore, in recent years, hot water mats adopting the traditional ondol method using hot hot water have been attracting attention in order to solve the problems of electric mats. Unlike hot water mats, hot water mats use hot water as a heat source, so they do not generate harmful electromagnetic waves due to electricity and have high energy efficiency.

  FIG. 1 is a schematic view showing such a hot water mat. As shown in FIG. 1, a conventional hot water mat 1 includes a mat 2 having a buffering force, a hot water pipe 3 that is arranged in a zigzag manner over the entire inner surface of the mat 2, and circulates hot water, and the hot water pipe. 3 includes a hot water boiler 4 connected to both ends of the hot water pipe 3 for supplying hot water heated to an appropriate temperature to the hot water pipe 3.

  Since such a hot water mat 1 is used only during a certain period of time in the winter season or season change, it must be folded and stored in the season when the hot water mat 1 is not used. However, in the case of the hot water mat 1, the hot water pipe 3 having a relatively large diameter is used as compared with the electric mat using the electric heating wire, and the hot water pipe 3 extends over the entire surface of the mat 2 in order to circulate the hot water. Since it must be continuously arranged, when folded and stored, and then expanded again, the folded portion of the hot water pipe 3 may be bent or cracked.

  If bending occurs in the hot water pipe 3 in this way, the hot water does not circulate smoothly and the original function of heating cannot be performed. In particular, if a crack occurs in the hot water pipe 3, there is a problem that the hot water flows out from the crack and may cause a fatal burn to the user. Therefore, in the technical field to which the present invention belongs, there is an urgent need for a method that allows the hot water mat to be folded in multiple stages and stored easily.

  The present invention has been made in view of the above problems, and has improved the hot water piping structure of the hot water mat, and the multi-stage folding hot water does not cause bending or cracking in the hot water piping even when the hot water mat is folded and stored in multiple stages. The purpose is to provide a mat.

  In order to achieve the above object, a multi-stage foldable hot water mat according to the present invention is formed of a plurality of unit mats partitioned by a fold line, and a mat portion that can fold adjacent unit mats around the fold line; A hot water pipe arranged in a zigzag manner inside each unit mat so as not to contact the folding line, and provided with at least one inlet and outlet; and an inlet of a hot water pipe of an adjacent unit mat; A hot water connecting pipe that interconnects the outlet is included, and the hot water pipe is not folded when the unit mat is folded around a folding line.

  Preferably, it further includes a hot water boiler for circulating hot water heated in the hot water pipe.

  Preferably, the hot water connection pipe is rotatably connected to an inlet and an outlet of the hot water pipe.

  Preferably, the hot water connecting pipe is made of a soft and extensible material.

  Preferably, the hot water connection pipe is detachable from the inlet and the outlet.

  Preferably, the mat portion further includes a protective cover capable of protecting the hot water connection pipe.

  Preferably, the mat portion can be separated for each unit mat.

  Preferably, the portion where the hot water pipe is bent is wrapped with a protective pipe made of an elastic material to prevent the hot water pipe from being bent, and the protective pipe is spring-like made of an elastic material.

  According to the present invention, since the mat portion of the hot water mat is separately formed by a plurality of unit mats, when not in use, the hot water mat can be easily folded and stored in multiple stages. Further, it is possible to prevent the hot water mat from being folded by overlapping the hot water pipe for circulating the hot water on the hot water mat in a state where the hot water mat is folded in multiple stages. Thereby, even when the hot water mat is folded and stored for a long time, the hot water pipe inside the hot water mat is not deformed or damaged, and the hot water mat can be used safely for a long time.

  The mat part 110 is formed of a plurality of unit mats 111, 112, 113 partitioned by a fold line 115. Each unit mat 111, 112, 113 can be folded in multiple stages around the folding line 115.

  In FIG. 2, the mat portion 110 is shown as a three-stage structure including three unit mats 111, 112, and 113, but the present invention is not limited to this, and is configured in two or three or more stages. You can also In addition, the mat part 110 can be manufactured to a size of a mattress that can be used by being laid on an indoor floor or bed for heating. However, as shown in FIG. Can also be used as a cushion.

  The mat portion 110 has the hot water pipe 120 disposed therein, and is heated by hot water circulating through the hot water pipe 120. The mat part 110 includes a material having a buffering force such as sponge. The mat unit 110 can be stored separately for each of the unit mats 111, 112, and 113. In this case, another fastening means such as a zipper or a Velcro tape is provided on the folding line 115 of the mat portion 110.

  The hot water pipe 120 is made of a material having good heat resistance and high heat transfer efficiency, and is arranged in a zigzag manner inside the mat portion 110. However, when the unit mats 111, 112, 113 of the mat part 110 are folded around the folding line 115, the hot water pipe 120 is disposed so as not to be in contact with the folding line 115 of the mat part 110. . That is, the hot water pipe 120 is arranged in a zigzag manner inside each of the unit mats 111, 112, 113 of the mat portion 110, and is provided with at least one inflow port 121a, 121b and outflow port 122a, 122b.

  The inflow ports 121a and 121b and the outflow ports 122a and 122b are provided on the side surfaces of the unit mats 111, 112, and 113 so that hot water flows into and out of the hot water piping 120 in the unit mats 111, 112, and 113. It is the entrance and exit. At this time, at least one of the inlets 121a and 121b and the outlets 122a and 122b is provided in the unit mats 111, 112, and 113, respectively. This is for connecting the hot water pipes 120 individually arranged on the unit mats 111, 112, 113 as one line, and the hot water pipes 120 arranged on the unit mats 111, 112, 113 adjacent to each other. The inlets 121a and 121b and the outlets 122a and 122b are interconnected via the hot water connecting pipe 130.

  As shown in FIG. 4, the hot water connecting pipe 130 is connected to the inlets 121 a and 121 b of the hot water pipe 120 disposed outside the mat portion 110 and inside the adjacent unit mats 111, 112, and 113. And the outlets 122a and 122b are connected to each other, and inflow and outflow of hot water are connected by one line. Further, it is desirable that the hot water connecting pipe 130 be formed in a size and a shape that protrudes to the outside of the mat portion 110 to the minimum.

  Specifically, in the hot water pipe 120, an inlet 121a and an outlet 122a located at the outermost part of the mat portion 110 are connected to the hot water boiler 140, and a first inlet 121a is formed on the right side of the first unit mat 111. The first outlet 122a is located, the second inlet 121b and the second outlet 122b are located on the left side, and similarly located on the next unit mat. At this time, in the unit mat 113 located at the terminal end opposite to the unit mat 111 connected to the hot water boiler 140, it is not necessary to transmit the hot water to the left side, so that the inlet 121 and the outlet 122 of the hot water pipe 120 are one. Configured one by one.

  The hot water connection pipe 130 includes an inner hot water connection pipe 131 that interconnects the second outlet 122 b of the first unit mat 111 and the first inlet 121 a of the second unit mat 112, and the first of the second unit mat 112. The outer hot water connecting pipe 132 interconnects the outlet 122a and the second inlet 121b of the first unit mat 111.

  The hot water connecting pipe 130 is made of a material having a high heat shielding efficiency, and is made of a soft material that does not bend or crack even if it is bent repeatedly.

  The hot water connection pipe 130 may be made of a stretchable material that is restored to its original state after being stretched, and is rotatably connected to the inlets 121a and 121b and the outlets 122a and 122b of the hot water pipe 120. . In this case, as shown in FIGS. 5a to 5c, the hot water connecting pipe 130 is connected to the inlets 121a and 121b of the hot water pipe 120 in a state in which the mat part 110 is spread. And the outlets 122a and 122b (FIG. 5a). Thereafter, when the mat portion 110 is gradually folded, the hot water connecting pipe 130 rotates in a direction opposite to the folding direction of the mat portion 110 (FIG. 5b). Next, when the mat part 110 is completely folded, the hot water connection pipe 130 continues to rotate while the mat part 110 is folded, and the inflow port 121a of the hot water pipe 120 is changed from a horizontal connection state to a vertical state. 121b and outlets 122a, 122b (FIG. 5c). Thus, only the mat part 110 can be folded without the hot water connecting pipe 130 being folded.

  The mat part 110 may further include a protective cover (not shown) that can protect the hot water connection pipe 130.

  As the hot water boiler 140, a known hot water boiler generally used for a hot water mat is used. For example, a hot water tank, a heater for heating water in the hot water tank, and water in the hot water tank are circulated through the hot water pipe 120. A circulating pump to be included.

  On the other hand, in the above embodiment, the case where the hot water connecting pipe 130 is always connected to the inlets 121a and 121b and the outlets 122a and 122b of the hot water pipe 120 has been described, but the present invention is limited to this. In addition, when the hot water mat 100 is not used, the hot water connection pipe 130 can be disconnected so that the connection between the hot water connection pipe 130 and the inlets 121a and 121b and the outlets 122a and 122b of the hot water pipe 120 can be released. Can be configured to be detachable. In this case, by adding a check valve function to the inlets 121a and 121b and the outlets 122a and 122b, water that can remain in the hot water pipe 120 flows out even if the hot water connection pipe 130 is separated. Can be prevented.

  In addition, as shown in FIG. 6, the hot water mat 100 according to the present invention may further include a protective pipe 125 made of an elastic material that can wrap the hot water pipe 120. This is because when the hot water pipe 120 is arranged in a zigzag shape, there is a certain section B where the hot water pipe 120 is bent, and the hot water pipe 120 may be damaged in the section.

  The protective pipe 125 is provided in the section B where the hot water pipe 120 is bent, and maintains the form of the section B where the hot water pipe 120 is bent, and can prevent this portion from being damaged. The protective pipe 125 may be a spring-like structural elastic body, or may be a material elastic body made of urethane or rubber.
