TECHNICAL FIELD [0001] The present invention is related to a heat mattress for bed having springs and heating wire that are electrically connected to an electric source for hating. Specifically, the present invention provides a heat mattress with a container and the container contains a binding post and is located between the springs not to be exposed to the outside, thereby shielding the user from electromagnetic waves radiated from the binding post. BACKGROUND ART [0002] One of the conventional heat mattress for bed is disclosed in Korean Patent 184360. In the mattress of this patent, heating wire are composed of two layers and each layer is formed in spiral shape, and the currents flowing in the inner layer and the current flowing in the outer layer are of opposite direction, which blocks 99.9 % of the electromagnetic waves from the wires. However, it cannot block the electromagnetic waves from the temperature controller or from the binding. post that electrically connects the wire to electric power. [0003] As the binding post and the controller are attached to the outer surface of the product to be exposed outside, the conventional mattress cannot shield the user from the electromagnetic waves. [0004] Also, when not in use as in summer, the controller exposed to the outside is an obstacle for a neat storing. Therefore, usually one should detach the controller for storing. DISCLOSURE OF THE INVENTION [0005] Accordingly, an objective of the present invention is to Provide a heat mattress for bed with the binding post located in Its inside for the electromagnetic waves not to reach the user. [0006] Another objective of the present invention is to protect the container from the damages caused from vibration or impact in use, by placing the container that contains a binding post between springs, and by securing the container to springs with a band to make the container move along the movement of the springs. [0007] Another objective of the present invention is to provide a heat mattress for bed having a zipper on its exterior near the location of the container so that the user can see the container inside and can put the temperature controller inside the mattress. [0008] To realize the above objects, the present invention provides a heat mattress for bed having springs and heating wire which are electrically connected to an electric source for heating comprise a container located between the springs and containing a binding post to supply electric power to the heating wire; and a shield located between the wires and the mattress and made of at least one of shield net or carbon fiber to shield electromagnetic waves. [0009] The heating wire are comprised of two layers and each layer is formed spirally, and the currents flowing in the inner layer and current flowing in the outer layer are of opposite direction that the electromagnetic waves caused by inner current and outer currents are offset with each other. [0010] The container is made of any one of iron, aluminum or ABS and has protrusions on its both sides for mounting. Each of the protrusions has a plurality of holes so that band passing through the holes ties the container to the spring. [0011] A zipper is provided to the exterior of the mattress so that a temperature controller controlling the temperature of the heating wire can be inserted into the container. [0012] The mattress can have two containers and each container can contain a temperature controller respectively. BRIEF DESCRIPTION OF THE DRAWINGS [0013] FIG. 1 schematically shows the shape of a mattress according to one embodiment of the present invention. [0014] FIG. 2 schematically shows the inner structure of a mattress according to one embodiment of the present invention. [0015] FIG. 3 schematically shows the container of FIG. 2. [0016] FIG. 4 schematically shows the connection of the container and springs. [0017] FIG. 5 schematically shows the connection of the temperature controller. [0018] FIG. 6 is the structural view shows the connection of plural controllers. BEST MODE FOR CARRYING OUT THE INVENTION [0019] With reference to the attached drawings, the embodiment of the present invention is described as below. Continue reading about Heat mattress for bed...
