The finish 26 is located at the top of the heating frame 21 and protrudes above the heating frame 21.

The heat insulating material 22 is formed in a double and the heat exchange passage 22a is formed in the upper heat insulating material heat exchange. The heat exchange passage 22a is formed in the form of a groove that penetrates the upper heat insulator and is open to the top as a whole. The heat exchange passage 22a is located directly below the heat transfer hot water pipe 25. The heat insulating material 22 is made of a foamed synthetic resin material compressed to be provided to minimize the loss of heat discharged to the lower portion of the heat transfer hot water pipe 25.

The heat storage plate 23 is seated on the upper portion of the heat insulating material 22, the heat conduction plate 24 is installed at the predetermined position, the heat transfer hot water pipe 25 is seated in a zigzag form on the heat conduction plate 24. The heat storage plate 23 absorbs heat emitted from the heat transfer hot water pipe 25 and conducts it in a planar manner. Since heat is stored in the heat storage plate 23 for a long time, heating can be performed for a long time even if the heat supply from the heat transfer hot water pipe 25 is stopped.

The heat conduction plate 24 is installed on the heat storage plate 23 to electrically conduct heat emitted from the heat transfer hot water pipe 25 to the heat storage plate 23 in a short time. The heat transfer hot water pipe 25 is seated in the mounting groove of the heat conduction plate 24.

The heat transfer hot water pipe 25 is configured to put the heating medium (water + steam) and the heating wire in the hot water pipe so that the hot water pipe itself performs heating and heat dissipation functions simultaneously without having a separate device for heating and circulating the hot water. Each end of the heat-transfer hot water pipe 25 is provided with a sealing device, the power supply line for supplying power from the outside is connected to the heating wire through the sealing device. The heat transfer hot water pipe 25 is arranged to be bent in a zigzag.

Heat generated in the heat transfer hot water pipe 25 is flatly conducted by the heat storage plate 23 and the heat conduction plate 24, and the same amount is discharged upward and downward of the heat transfer hot water pipe 25. The heat dissipation temperature in the heat transfer hot water pipe 25 may be freely adjusted by the control box 30.

The air flowing in through the air inlet 28 formed at a position lower than the heat exchange passage 22a is positioned to face the bottom of the bed and passes through the heat exchange passage 22a to exchange heat with heat discharged from the heat transfer hot water pipe 25. The temperature rises. The air whose temperature is raised is discharged through the air discharge port 29 formed at a position higher than the heat exchange passage 22a. That is, only the natural convection of the air can transfer the heated air through the heat exchange passage 22a.

The heated air discharged through the air discharge port 29 is supplied to the upper part of the bed. Therefore, heat efficiency is obtained by using heating air obtained by using radiant heat directly discharged to the bottom of the bed through the heat storage plate 23 and the heat conduction plate 24 and heat discarded below the heat transfer hot water pipe 25. Can be increased.

Meanwhile, the slider 140 to which the belt 180 is coupled is located at the leg of the bed, but the present invention is not limited thereto, and the slider to which the belt 180 is coupled may be located at the head of the bed. In the former case, the thermal insulation film 110 is opened while sliding toward the head of the bed, and in the latter case, the insulation film 110 is opened while sliding toward the leg of the bed.

Hereinafter will be described in detail the operation according to the insulating film opening and closing device of the present invention configured as described above.

First, the user rotates the driving motor 160 in one direction by using the controller 130 to lie in the bed and slides the two sliders 140 coupled with the belt 180 toward the head of the bed. When the two sliding members 140 are slid, the thermal insulation frame 120 coupled thereto also slides toward the head of the bed, and in the sliding process, the other sliding member 140 and the thermal insulation frame 120 are moved toward the head of the bed. Slide and slide together. Therefore, as shown in FIG. 14, the thermal insulation film 110 is opened to open the space on the bed.

When the thermal insulation layer 110 is opened and the bed is opened, the user climbs on the bed to lie down and operates the controller 130 to keep the thermal insulation layer 110 closed. That is, by operating the controller 130 to rotate the drive motor 160 in the opposite direction than when the thermal insulation film 110 is opened, the two sliders coupled to the belt 180 while the belt 180 rotates in the opposite direction. Sliding 140 toward the leg portion, while the thermal insulation film 110 is pulled out in the process of sliding, the insulation film frame 120 coupled with the insulation film 110 also slides toward the leg portion. Therefore, as shown in FIG. 13, the thermal insulation film 110 is closed to close the space on the bed.

As described above, the present invention has been described based on the preferred embodiments, but the present invention is not limited to the specific embodiments, and those skilled in the art may change the scope within the scope of the claims.
