Description

  The present invention relates to a duct holding member that holds a heat insulating material adhered to an inner wall of an exhaust duct so as not to peel off.

  In air conditioning facilities and dryers in buildings, ducts are connected to an exhaust port that leads to the outside of the building to discharge heated air and the like. The duct connects a plurality of pipes formed of metal or the like into a shape such as a square tube or a cylinder, and is arranged on the back of the ceiling or under the floor of the building. When the temperature of the air passing through the duct becomes high, the duct itself becomes hot, so that a heat insulating material may be attached to the outer wall or the inner wall of the duct.

  Further, if there is a temperature difference between the inside and outside of the duct, condensation occurs and causes the duct to corrode. However, condensation can be reduced by using a heat insulating material. As described in Patent Document 1, an invention of a heat insulation duct that can maintain heat insulation performance in an excellent state over a long period of time without deteriorating heat insulation even when condensation occurs is also disclosed.

  First, the exhaust duct using the duct pressing member according to the present invention will be described. FIG. 1 is a perspective view showing an exhaust duct using a duct holding member. FIG. 2 is an enlarged cross-sectional view of a connecting portion of the exhaust duct using the duct pressing member.

  As shown in FIG. 1, the exhaust duct 100 includes a tube body 200 with flanges 210 at both ends, a heat insulating material 220 attached to the inner wall of the tube body 200, and heat insulation from one end to the other end of the tube body 200. A plate-like pressing member 300 and the like are arranged so as to press the material 220 against the tube body 200. The pressing member 300 is sandwiched between packings 230 that are interposed when the tip 310 is bent along the flange 210 of the tube body 200 and connected to the adjacent tube body 200a.

  The tubular body 200 is formed by processing a plate material of an arbitrary thickness such as a metal such as stainless steel into a cylindrical shape having a predetermined length on both bottom surfaces. The plate material may be bent to have a rectangular cross section to form a rectangular tube, or may be bent into an annular shape and formed into a cylindrical shape. In addition, since a plurality of pipe bodies 200 are connected and connected from the indoor apparatus body to the outdoor exhaust port, the pipe body 200 may be bent, branched or merged in order to change the direction. .

  The tube body 200 is formed with a flange 210 in which both ends are bent outward in order to connect a plurality. By combining the flange 210 of one pipe body 200 and the flange 210 of another pipe body 200, the pipes are connected so as to be in a sealed state.

  A heat insulating material 220 is attached to the inside of the tube body 200 so as to cover the entire inner wall. Note that the heat insulating material 220 may be attached to the tube body 200 using an adhesive or the like so as not to be peeled off. However, when the temperature of air passing through the inside of the tube body 200 becomes high, it has heat resistance. Those are preferred. In addition, the heat insulating material 220 may be pressed by the pressing member 300.

  The heat insulating material 220 may be made of a fiber type such as glass wool or rock wool, or a foam type such as urethane, polystyrene, or foamed rubber. In addition, what is necessary is just to determine the thickness of the heat insulating material 200 according to the diameter of the pipe body 200, and the required heat insulation performance. Further, in the case where condensation occurs, a water-absorbing material may be used.

  The holding member 300 is arranged inside the tube body 200 so as to pass from the bottom side of one end of the tube body 200 to the bottom side of the other end, and presses the heat insulating material 220 against the tube body 200 along the surface of the heat insulating material 220. It is attached as follows. The pressing member 300 may be an elongated strip-shaped metal plate.

  The pressing member 300 may hold at least one surface of the inner wall, but may hold all four surfaces. Further, it may be pressed by one pressing member 300 per surface, or may be pressed by a plurality of (for example, two) pressing members 300.

  As shown in FIG. 2, the case where the right pipe body 200 and the left pipe body 200 a are connected in the exhaust duct 100 will be described. A heat insulating material 220 is attached to the inner wall of the tube body 200, and the heat insulating material 220 is pressed by the pressing member 300. Is held down.

Similarly, the tip 310a of the pressing member 300a is bent outward from the tube body 200a and the heat insulating material 220a along the flange 210a, and is temporarily fastened to the flange 210a using a fastener 320 or the like. The

  The packing 230 is sandwiched between the flange 210 of the tube body 200 and the flange 210a of the tube body 200a, and the retaining holes penetrated through the flange 210 and the retaining holes penetrated through the flange 210a Tighten through bracket 240. The packing 230 may be made of an airtight and heat resistant resin or rubber.

  The holding members 300 and 300a may be sandwiched using the elasticity of the packing 230. The pressing members 300 and 300a are held by the packing 230, and the heat insulating materials 220 and 220a are pressed against the pipes 200 and 200a. It can suppress that the heat insulating materials 220 and 220a peel and a clearance gap produces between the pipe bodies 200 and 200a.

  According to this invention, it can hold | suppress so that the heat insulating material stuck to the inner wall of an exhaust duct may not peel. Since the heat insulating material does not peel, the condensation of the exhaust duct is suppressed and corrosion is prevented, thereby extending the life of the exhaust duct. In addition, there is no possibility that the device existing in the duct path is damaged by being peeled or the duct is clogged by being caught in the device.

  Next, an application example of the exhaust duct using the duct pressing member according to the present invention will be described. FIG. 3 is a perspective view showing an overview of a heat sterilizer equipped with an exhaust duct using a duct pressing member.
