Title: Heat reflection tent

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a heat-reflection tent, and more particularly to a heat-reflection tent of a portable sauna that has a good supporting capacity and is convenient for a user to pass in and out. 
     2. Description of Related Art 
     With reference to  FIG. 6 , a conventional heat-reflection tent  90  is suitable for a portable sauna and has a body  91  and a zipper  92 . The body  91  has a top surface, a front surface, a chamber  94 , and a neck opening  93 . The chamber  94  is formed in the body  90 . The neck opening  93  is formed in the top surface of the body  91  and communicates with the chamber  94  of the body  91 . The zipper  92  is mounted on the front surface of the body  91  and extends from a bottom of the front surface of the body  91  to the neck opening  93  of the body  91  for dividing the front surface of the body  91  into two front sheets  95 . A user can open the two front sheets  95  of the body  91  by the zipper  92  and enter the chamber  94  of the body  91  via the opened front sheets  95 . However, the body  91  of the conventional heat-reflection tent  90  is collapsed easily and can hardly maintain a shape of the body  91  without a supporting structure. The zipper  92  mounted on the collapsed body  91  is hard to open. 
     With reference to  FIG. 7 , a heating device  80  is disposed in the chamber  94  of the body  91  adjacent to the front surface of the body  91 . A remote control  83  is electrically connected to the heating device  80  and is disposed on the body  91 . A footrest  82  is disposed in the chamber  94  of the body  91  and is adjacent to the zipper  92 . Two shafts  81  are respectively mounted on two sides of the heating device  80  and are located at two front corners of the conventional heat-reflection tent  90  for supporting two sides of the conventional heat-reflection tent  90 . The shape of the body  91  can be maintained by the two shafts  81 . The zipper  92  is easy to be opened or closed. 
     However, the heating device  80  is adjacent to the front surface of the body  91  and is adjacent to the bottom of the zipper  92 . When the user opens the zipper  92  and enters the chamber  94  of the body  91 , the user needs to step over the footrest  82 . Elderly people or people with injured feet may be tripped and injured by the footrest  82  during the process of stepping into the chamber  94  of the body  91 . In addition, the zipper  92  is opened to separate the two front sheets  95 . Bottoms of the two front sheets  95  are still connected to a bottom surface of the body  91 . The opening diameter of the zipper  92  is decreased downwardly. The difficulty for the user to step into the chamber  94  of the body  91  is increased. 
     To overcome the shortcomings, the present invention provides a heat-reflection tent to mitigate or obviate the aforementioned problems. 
     SUMMARY OF THE INVENTION 
     The objective of the invention is to provide a heat-reflection tent that can solve the shortcoming that a supporting capacity of the conventional heat-reflection tent is insufficient, causing inconvenience in operating the zipper, and the difficulty for the user to step into the chamber of the body is increased by the conventional heat-reflection tent with the heating device and the two shafts. 
     The heat-reflection tent has a body and a supporting member. The body has a covering cloth and a zipper assembly. The covering cloth has a front portion, a top surface, a bottom surface, two side surfaces, an inner surface, a front surface, a chamber, and a neck opening. The front portion of the covering cloth has a bottom and two covering sheets. The two covering sheets are disposed beside each other. The front surface of the covering cloth is formed on the front portion of the covering cloth. The chamber is formed in the covering cloth. The neck opening of the covering cloth is formed in the top surface of the covering cloth and communicates with the chamber of the covering cloth. 
     The zipper assembly is mounted on the covering cloth and has a front zipper and two bottom zippers. The front zipper is mounted on the front portion of the covering cloth, is located between the two covering sheets of the front portion, and upwardly extends from the bottom of the front portion to the neck opening. The two bottom zippers are mounted on the bottom of the front portion, are respectively disposed on the two covering sheets of the front portion, and extend to the front zipper. 
     The supporting member is mounted on the body and has a bottom rod and two side rods. The bottom rod is mounted on the covering cloth of the body adjacent to the bottom of the front portion and has two ends adjacent to the two side surfaces of the covering cloth respectively. The two side rods are respectively mounted on the two ends of the bottom rod, extend upwardly, and each side rod has a respective top end. The top ends of the two side rods are respectively connected to the two side surfaces of the covering cloth and extend to the top surface of the covering cloth. 
     The supporting member is used to support the body for keeping a shape of the body. The supporting member is located adjacent to the front surface of the covering cloth. In use, a shape of the covering cloth can be maintained by the supporting member. The front zipper and the two bottom zippers of the zipper assembly can be opened smoothly by a user. When the two bottom zippers are opened, two bottom portions of the two covering sheets can be separated for increasing an opening range of the two covering sheets. A distance between the two separated covering sheets is increased for allowing the user to enter the chamber easily. A chair or a heat device is easily put into the chamber of the covering cloth. Furthermore, the heating device is disposed in the chamber of the covering cloth according to the needs of the user and is disposed at a position where the user is free from tripping, thereby improving the safety of using the heat-reflection tent.

     With reference to  FIGS. 3 to 5 , the body  10  is supported by the supporting member  20 . Two sides of the front surface of the covering cloth  11  can stand erectly. When a user opens the zipper assembly  12 , the front zipper  15  and the two bottom zippers  16  of the zipper assembly  12  can be opened smoothly and easily. When the zipper assembly is opened, the two covering sheets  17  are opened forward, and two bottom portions of the two covering sheets  17  can be separated for increasing an opening range of the two covering sheets  17 . The two side rods  22  of the supporting member  20  are covered by the two side covers  105  of the covering cloth  11  and respectively support two sides of the covering cloth  11 . The two sides of the covering cloth  11  can stand erectly and firmly. 
     The opening range of the two covering sheets  17  is increased by the two bottom zippers  16 . The covering cloth  11  is supported by the two side rods  22  of the supporting member  20  for keeping a shape of the covering cloth  11 . A chair  30  can be easily put into the chamber  14  of the covering cloth  11  via the opened covering sheets  17 .
