Heat medium circulation type mat

The present invention relates to a heat medium circulation type mat for circulating a heat medium to heat a heated body, and more particularly, to prevent the pipe that transports the heat medium from being ruptured due to internal pressure. The present invention relates to a heat medium recirculating mat capable of preventing the heat medium from leaking when it is separated, improving the granulation, and shortening the time required to heat the heat medium.

Currently, the mat is widely used as an electric mat that heats the object to be heated by heat generated by electric resistance when electric current flows in the heating wire, which is a direct heating method. In addition to the high risk, there were various problems in use, such as the emission of harmful electromagnetic waves during the heat generation process. Recently, there is no such problem, and it is noticed that the heat medium (usually water is used) is transferred from the heat source. It is a heat medium circulation type mat of indirect heating type that circulates through and heats the heating target object.

1 is a plan view showing the configuration of a heat medium circulation mat according to the prior art.

As shown in FIG. 1, the heat medium recirculating mat according to the related art includes a mat main body 110 including a cushion, an outer shell, and the like, and a predetermined portion (mat main body) inside the mat main body 110. Flow path forming means 120 for forming a plurality of flow paths 125a and 125b so that the heat medium flows according to the upper part where the upper body is positioned and the lower part where the lower body is located when lying on the back, and each flow path 125a ( The heat medium supply means 130 which supplies a heat medium to one of both ends of 125b, and collects the heat medium which passed through the flow paths 125a and 125b from the other end, and this heat medium supply means 130 and the flow path 125a It is installed to act as a cross-linking between the (125b) and consists of a tube for transporting the heat medium between the two.

The flow path forming means 120 has an inlet and an outlet formed at one side of the tube or the main body of the channel (125a, 125b), and the tubes are coupled to each other. Bars 125a and 125b are formed so as to flow out, and each of the flow paths 125a and 125b is formed to have a constant cross-sectional area to prevent the heat of the heat medium from being unevenly distributed.

The heat medium supply means 130 is composed of a tank in which the heat medium is stored, a heater for heating the heat medium inside the tank to be maintained at a constant temperature, and a pump for circulating the heat medium inside the tank by passing it to the flow paths 125a and 125b. do.

The tube is provided with the main tube 141 for supply and the main tube 142 for recovery coupled to the tank of the heat medium supply means 130, and either one of both ends of each of the flow paths 125a and 125b. Each of the plurality of supply branch tubes 143a and 143b coupled to each other, and the plurality of recovery branch tubes 144a and 144b respectively coupled to the other side, and the heat medium discharged from the supply main tube 141 are supplied. Supply connection tube 145 for distributing to the branching tubes 143a and 143b for connection and the heat medium flowing out from each of the collecting branch tubes 144a and 144b is collectively connected to the collecting main tube 142. It consists of a connecting tube 146 for recovery.

Here, each of the supply branch tubes 143a and 143b and the recovery branch tubes 144a and 144b may be formed outside the mat body 110 of the flow path forming means 120 when the flow path forming means 120 is formed of a tube. Exposed ends.

Reference numerals 150a and 150b not described in FIG. 1 are control valves respectively installed in the supply branch tubes 143a and 143b to adjust the amount of the heat medium supplied to each of the flow paths 125a and 125b.

In the prior art as described above, when each of the control valves 150a and 150b is opened and the heating medium supply means 130 is operated, the heated heating medium is supplied from the main tube 141 for supply → the connecting tube 145 for supply → After passing through the branching tubes 143a and 143b, they are collectively supplied to each of the passages 125a and 125b, and after passing through the passages 125a and 125b, the branching tubes 144a and 144b are recovered. Connecting tube 146 → The main body 142 for recovery is collectively recovered to the heat medium supply means 130, the mat body 110 is heated to a predetermined temperature by the heat medium circulating while repeating this series of processes .

At this time, when any one of the control valves 150a and 150b is closed, the pipeline of the supply branch tube is blocked and the heating medium supply to the flow path coupled thereto is stopped, thereby heating except for the portion where the flow path is disposed. .

However, in the heat medium circulation mat according to the prior art, first, the cross-sectional area of the flow paths 125a and 125b is constant, and the main tube 141 for supply, the main tube 142 for recovery, the branch tube 143a and 143b for supply are provided. ), The feeder tube 145 and the feeder tube 146 for recovery are also divided into several parts at one end of the tube. When viewed as a whole, the size of the pipes formed by them is constant, and the internal pressure is increased due to the volume expansion of the heating medium due to heating and the compression of the flow paths 125a and 125b according to the external force (weight of the user, etc.). There was a problem that the weak part of the pipeline was squeezed or cracked due to this constant and repetitive stress.

Second, when the main tube 141 for supply and the main tube 142 for recovery are separated from the supply connection tube 145 and the recovery connection tube 146 for maintenance and repair, Since the coupling hole where the supply main tube 141 and the recovery main tube 142 of the accommodating connection tube 146 are coupled is broken, the heat medium of the flow paths 125a and 125b flows out as it is. There was a problem to throw away.

Of course, if the control valve (150a, 150b) is in the closed operation state, the heat medium can be prevented from leaking from the supply connection tube 145, but it was not possible to prevent the heat medium from leaking from the recovery connection tube 146. will be.

If the recovery branch tubes 143a and 143b are connected to the recovery connection tube 146 in a state of being connected to the flow paths 125a and 125b, the supply branch tubes 143a and 143b may be connected. The coupling is connected to the control valves 150a and 150b while being connected to the flow paths 125a and 125b and the coupling valves 150a and 150b and the supply connection tube 145 are connected to each other. The troublesome and time-consuming work was difficult.

Fourth, since the heat medium that lost heat in the process of passing through the flow path (125a, 125b) is recovered to the heat medium supply means 130 as it is, the time required to heat the heat medium stored in the tank is inevitably long. there was.

The present invention has been made to solve the problems of the prior art, the tube connector (connecting tube for supply, connecting tube for recovery) connecting the main tube for supply and supply branch tube, recovery main tube and recovery branch tube. It is possible to prevent the rupture of the pipe due to the pressure increase by changing the structure of the pipe and forming a space to expand the pipe in the inside so that the rising pressure is absorbed when the internal pressure is increased. According to the separation or not, the coupling hole to which the supply main tube and the recovery main tube are respectively opened and closed automatically prevents the heating medium from leaking out of the coupling hole when the supply main tube and the recovery main tube are separated. It is an object of the present invention to provide a heat medium circulation mat.

Another object of the present invention is to provide a heating medium circulation mat that can be assembled in a convenient and quick tube by installing a control valve to the tube connector to be configured to be directly coupled to the feed branch tube to the tube connector.
