DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in the figures
A three-foldable adult-size mat body 5 is constructed by stacking the soft upper core material 2 in a stack and detachably attaching a cover 4 with a slide fastener 3 for opening and closing. An aluminum film 6 as a heat reflection plate is stuck on the upper surface of the lower core material 1 and an embedding space 7 is formed on the lower surface of the upper core material 2, and a heat storage type heating element 8 described below is inserted therein. Thus, a nap mat 9 for a driver such as a truck having the heat storage type heating element 8 in the foot and the waist is formed.

The heat storage type heating element 8 comprises a flat and hollow case 11 made of hard plastic, and a portion on a single meandering line selected in the entire lower surface wall 12 of the case 11 is inwardly recessed. The cross section of the wall 12 has a rectangular wave shape, and a cord type heater 14 is inserted in the concave meandering groove 13.
, And at both ends of the cord-shaped heater 14,
Through the heat storage order controller 15 and the lead 16 provided with a configuration for ending the heat storage of all the heat bodies in such an order that the heat storage of the waist heat body 8 starts after the heat storage of the foot heat body 8 is completed. The connection plug 17 is connected to the magnetic metal plate 2 at a position between the pins 18 and 19 of the connection plug 17.
0, and a connection socket 21 paired with the connection plug 17 at the tip and a power outlet (not shown) directly connected to a battery (not shown) provided in a vehicle such as an automobile at the base. A power cord 23 having a power receiving plug 22 inserted into the power cord 23 (not shown) is configured.
A magnet 28 with yokes 26 and 27 is embedded at a position between the insertion holes 24 and 25 in the connection socket 21 of
The outer ends of the yokes 26, 27 of the magnet 28 are attracted to the magnetic metal plate 20 when the pins 18, 19 of the connection plug 17 are inserted into the insertion holes 24, 25, and the case The heat storage solution 3 from the stopper 30 into 11
1 are sealed, and two of them are inserted into the embedding space 7 in a state of parallel connection (a form in which power is received from one power cord 23).

In the drawings, reference numeral 33 denotes a thermostat, reference numeral 34 denotes a thermal fuse, which are connected to the heater circuit and fitted in a recess formed on the wall surface of the case 11.

The above-described heat storage order controller 15 can be used in a temperature sensor management system in which the energization of the next heating element is started when the first heating element is heated to a predetermined temperature.
An energization time management method in which the energization of the next heating element is started after the energization of the second heating element has been performed for a predetermined time, or another method may be used. The above embodiment is based on the former.

The rating of the above embodiment is as follows. Rated voltage of battery: DC12V Rated power consumption: 60W × 2 Rated current: 5A × 2 Heat storage (energization): Approximately 1.5 hours (normal temperature) Surface temperature approximately 43 ° C Radiation time Approximately 7 hours (normal temperature) Size: 1800L × 500W × 45H (mm) (3 fold) Fuse rating: 6A

[0011]

According to the present invention, in the case of the configuration as in the above embodiment, the heat storage solution is sealed in a hollow flat case, and a heater for heating the solution is provided on the lower surface of the case. Since the case and the heater are buried in the nap mat body in a stacked state, it is convenient to use it by laying it in a nap room or the like of a large truck.In this use, the heater is supplied from an outlet provided in the truck. After the solution in the case is warmed up, the cord can be pulled out and removed, that is, it can be brought into a nap room or the like after it has been warmed up and used. A nap can be performed in a comfortable state with the engine stopped, without disturbing the surroundings, and idling is unnecessary, which is suitable for saving gasoline. The main body is the size of an adult and the folding line is provided on a plurality of lines perpendicular to the longitudinal direction and a hard core material that is hard to bend is put on the lower surface, so even if the nap place is slightly uneven, it will bend due to the unevenness The solid core portion prevents the occurrence of stiffness and maintains a flat state, which is not only convenient for sleeping well, but also causes the end of the mat body to float off the end of the seat. If the area of the part is small, it can be used without any problem if the area is small.Furthermore, the heater is a cord type, the cross section of the wall provided with the heater in the case is wavy, and a concave groove is formed on the outer surface of the wall. Since the cord type heater is formed in the groove, the heater can heat the solution efficiently through the bottom wall and both left and right side walls of the groove when heating the solution, that is, from three directions efficiently, And especially many A plurality of heating elements buried in each place end the heat storage of all the heating elements in order so that the heat storage of the second heating element starts after the heat storage of the first heating element is completed. With a power cord connected via a heat storage sequence controller with an electric circuit of
Since the battery receives power from a battery (not shown), the battery always has insufficient power for one heating element, causing insufficient heating or requiring a longer time than expected for heating. It has the advantage of completely achieving the intended purpose of eliminating inconveniences such as accidental inconvenience.
