Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an extremely easy-to-use foot warmer with a cushion that can be used arbitrarily in a cordless state as a cushion or a foot warmer.

[0002]

[Prior art]

 In general, it is relatively common to live in a chair or the like and to sit on a tatami mat or on the floor, and the proportion of such lives is almost evenly divided.

[0003] There are various types of articles that can cope with the above-mentioned life patterns, but all of these are inconvenient to use, inconvenient to clean up when not in use, and have a thermal efficiency of the heater. It had one or more of the following defects: bad, power cord was in the way.

[0004]

[Problems to be solved by the invention]

 The purpose of the present invention is to provide a new foot warmer that has been devised to completely eliminate all of the above-mentioned defects and other devises.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the foot warmer according to the present invention encloses a heat storage solution in a hollow flat case, provides a solution heating heater on the lower surface of the case, and stacks these cases and heaters. In this state, the floor is buried in the footrest, and a cushion is provided on the lower surface of the footrest. A groove is formed, and a cord-type heater is loaded in the groove, and a connection plug and a connection socket having a detachable structure for maintaining a connection state by suction between a magnet and a magnetic metal plate. Thus, a cord-type heater is connected to a power cord for supplying power to the cord-type heater.

【Example】

 In the embodiment shown in the figure, a soft sponge upper core material 2 is superimposed on a hard sponge lower core 1 and a cover 4 with a slide fastener 3 for opening and closing is detachably attached thereto. A footrest 5 is formed, and a space 7 for embedding and placing is formed on the lower surface of the upper core material 2 in the footrest 5 and a heat storage type heat retaining tool 8 described below is inserted into the space 7. The foot cover member 6 is attached to the upper surface of the foot warmer, thereby constituting the foot warmer body 9 containing the heat storage type heat retaining tool 8, and the lower surface of the foot warmer body 9 is integrally provided with the cushion member 10 containing the thin batting 29. It is.

The heat storage type heat retaining device 8 is formed of a flat, hollow case 11 made of hard plastic, and a portion on one meandering line set on the entire lower surface 12 of the case 11 is inwardly recessed. The cross section of the wall 12 has a rectangular wave shape, and the cord type heater 14 is indented along the groove 13 in the meandering concave groove 13, and the connecting plug 17 is connected to both ends of the cord type heater 14 through the lead wire 15. And a magnetic metal plate 20 is fixed at a position between the pins 18 and 19 of the connection plug 17, and a connection socket 21 paired with the connection plug 17 is separately provided at the end separately. A power cord 23 having a power receiving plug 22 to be inserted into a power outlet (not shown) is formed at the base end, and a yoke is provided at a position between the insertion holes 24 and 25 in the connection socket 21 of the power cord 23. 26, When the pins 18 and 19 of the connection plug 17 are inserted into the insertion holes 24 and 25, the outer ends of the yokes 26 and 27 of the magnet 28 The heat storage solution 31 is sealed in the case 11 from the plug 30.

In the drawing, reference numeral 33 denotes a thermostat, 34 denotes a thermal fuse, and these are connected to the heater circuit and are fitted in recesses formed in the wall surface of the case 11.

In the case of the above embodiment, a foot temperature effect of about 9 hours or more could be obtained by energizing for about 45 minutes.

The present invention can be as follows. a. A magnet is used at the connection between the mat body 5 and the power cord to facilitate the continuous operation, but the direct connection reduces the cost. b. Since the hollow case 11 becomes soft and easily deformed when it becomes hot, it is placed in an aluminum case and reinforced by this to prevent deformation. c. The foot covering member 6 is detachable with a fastener or the like. d. The foot warmer body 9 and the cushion section 10 can be separated arbitrarily. e. Provided in a type that can be used by connecting to a power outlet provided in vehicles such as automobiles.

[0011]

[Effect of the invention]

 Since the foot warmer according to the present invention has the above-described configuration, the foot warmer body is used when sitting on a chair in a daily life pattern, and when sitting on a tatami or floor. The cushion is very convenient because it can be used, and when it is used in this way, it is soft and warm, and it is good for your body. After the solution inside is warmed up, the cord can be removed and removed, that is, it can be used in accordance with daily life as described above after it is warm, and it can be used in a warm state without connecting the power cord. It is well-formed and safe, and furthermore, the heater is provided in a case in which the cross-section of the wall on which the heaters are provided is corrugated, and a concave groove is formed on the outer surface of the wall, and a cord-type heater is loaded in the concave groove. Therefore, when the heater heats the solution, there is an advantage that the heater can efficiently and speedily heat the solution through the bottom wall and the left and right side walls of the groove, that is, from three directions. When the plug for connection and the socket for connection are removed, it has a practical effect that it can be carried and used as a so-called cordless.
