Heat mattress for bed

Abstract

The present invention is provided to a heat mattress for bed having springs and heating wire which are electrically connected to an electric source for heating, which comprises 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. According to the present invention, an advantage of the present invention is that the binding post is located inside for the electromagnetic waves not to be reached at the user.

1 . A heat mattress for bed having springs and heating wire which are electrically connected to an electric source for heating, comprising: 
 a container located between said springs and containing a binding post to supply electric power to said heating wire; and    a shield located between said wires and said mattress and made of at least one of shield net or carbon fiber to shield electromagnetic waves.    
   
   
       2 . A heat mattress according to  claim 1 , wherein said heating wire are comprised of two layers and each layer is formed spirally, and the current flowing in the inner layer and the 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.  
   
   
       3 . A heat mattress according to  claim 2 , wherein said container is made of any one of iron, aluminum or ABS and having protrusions on its both sides for mounting.  
   
   
       4 . A heat mattress according to  claim 3 , wherein each of said protrusions have a plurality of holes so a band pass through the container can tie the container to the spring.  
   
   
       5 . A heat mattress according to any one of  claims 1  to  4 , a zipper is provided to the exterior of said mattress so that a temperature controller which controls the temperature of the heating wire can be inserted into the container.  
   
   
       6 . A heat mattress according to  claim 5 , wherein the mattress have two containers and each container can contain a temperature controller respectively.
