[0020] FIG. 1 schematically shows the shape of a mattress 100 and
FIG. 2 is a vertical sectional view (A-B) of inner structure of a
mattress according to one embodiment of the present invention.
[0021] The exterior of the mattress 100 is composed of fabric 102.
The inside of mattress 100 are shield surface 104, heating wire
106, top cover 108, springs 110, bottom cover 112 and a container
114.
[0022] The shield surface 104 is made of shield net or carbon
fiber. The shield net can be copper net, silver net, iron net,
etc.
[0023] This shield surface 104 blocks the electromagnetic waves
emitted from the heating wire 104 and makes the waves not to reach
the user. For this, the shield surface 104 is located between
heating wire 106 and fabric 102 to block the electromagnetic
waves.
[0024] The heating wire 106 has a core made of ceramic, an inner
heating wire spirally wrapping the core, the ceramic insulator
wrapping the inner wire and an outer heating wire spirally wrapping
the ceramic insulator in opposite direction.
[0025] Therefore, the currents flowing in the inner wire and the
current flowing in the outer wire are of opposite direction with
each other and are offset so that the electromagnetic waves are not
emitted outward.
[0026] This art is disclosed at the Korean patent 184360 in
detail.
[0027] The top cover 108 and the bottom cover 112 are made of
pressed cotton. They secure the springs 110 in the mattress 100 and
increase cushion effect and comfort.
[0028] The springs 110 are arranged at the inside of the mattress
100 with regular interval between them and can absorb the
shock.
[0029] The fabric 102, the covers 108, 112, and the springs 110 are

according to the size of itself and/or springs 110.
[0032] The container 114 can be made of iron, aluminum, ABS, etc.
and can endure the shock or the vibration without causing
damage.
[0033] The binding post 130 is mounted in the container 114 and
supplies the power to the heating wire 106. While supplying the
power, the binding post 130 emits a little electromagnetic
wave.
[0034] Protrusions 132 are formed on both sides of the container
114. One or more holes are formed at the protrusion 132 to let the
band 134 passes through.
[0035] FIG. 4 schematically shows how to connect the container to
springs.
[0036] A band secures the container 114 and the springs 110. The
band 136 passes through the holes 134 and two opposite springs 110.
Therefore, the container 114 and two opposite springs 110 are fixed
together. Accordingly, when the springs 110 make movement, the
container 114 also move according the movement of the springs
110.
[0037] The band 136 can be made of materials that are not only
strong but also flexible such as rubber, vinyl, fiber or iron.
[0038] FIG. 5 schematically shows how to connect the temperature
controller.
[0039] A zipper 150 is formed on the exterior of the mattress 100
near the area where the container is located. If the zipper 150 is
opened, the container 114 and the binding post can be observed.
[0040] The binding post 130 is electrically connected to a lead
line 202. The lead line 202 is connected to a temperature
controller 204 that controls the current flowing in the heating
wire 106 to control the heating power.
[0041] The plug 206 is formed on the opposite face of the
temperature controller 204.
[0042] The container 114 has the space in which the controller 204
