Abstract

<P>PROBLEM TO BE SOLVED: To provide a hood body installable in correspondence with an exhaust pipe even when the outside diameter dimension of an exhaust pipe used is different from that of the exhaust pipe used for the hood body. <P>SOLUTION: A mounting plate 3 is fixed to an opening part 4 formed in the peripheral edge step part 2 of the hood body 1, and a flange edge part 5 bent in the outside direction or inside direction at the opening part for inserting the exhaust pipe therein is formed on the mounting plate. Spring claws 7 are projectedly formed at the opening part at proper intervals in the outer diagonal directions, and the mounting plate is fixed so as to be bitten in the outer peripheral surface part of the exhaust pipe inserted into the opening part by the spring claws. The spring claws may be projectedly formed directly on the mounting plate at intervals in the outer diagonal direction without forming the flange edge part at the opening part in the outer or inner direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a ventilation device, and more particularly, to an attachment structure for an exhaust pipe penetrating an outer wall and a hood body.

  Conventionally, as means for connecting a hood body to an exhaust pipe that communicates indoors and outdoors with an outer wall separated, for example, Japanese Patent No. 3135208, Japanese Patent Laid-Open No. 2000-120938, Japanese Patent Laid-Open No. 2002-81708, Japanese Patent Laid-Open No. 2002-130757, Although technologies such as 2003-202143 and 2004-12086 are known, there are several types of exhaust pipes having different outer diameters (in the current JIS, VP pipe 100 × 114 mm / VU pipe 107 × 114 mm / SU Therefore, in order to securely insert and attach the exhaust pipe to the exhaust pipe, in order to prepare a plurality of hood bodies having different caliber sizes of the attachment ports or to assist the attachment of both. It took a lot of time to prepare the joints.

  However, this increases the material cost, and the construction work of the hood body on the exhaust pipe has been a problem because it lacks economic efficiency.

Japanese Patent No. 3135208 Japanese Patent Laid-Open No. 2000-120938 JP 2002-81708 A JP 2002-130757 A JP 2003-202143 A Japanese Patent Laid-Open No. 2004-12086

  Therefore, the present invention provides a structure in which the hood body can be quickly attached to the exhaust pipes having different outer diameters as described above by providing the opening on the hood body side as described above. An object of the present invention is to provide a highly economical ventilation device that eliminates the drawbacks.

  The present invention fixes a mounting plate to an opening formed by being surrounded by a peripheral step of the hood body, and the mounting plate is bent to the outer side or the inner side at the opening into which the exhaust pipe is inserted. And a protruding claw projecting in an obliquely outward direction at an appropriate interval from the opening, and fixed so as to bite into the outer peripheral surface portion of the exhaust pipe fitted into the opening by the protruding claw.

  In the opening portion, the ridged claw may be provided in an obliquely outward direction at an appropriate interval without forming the heel edge portion in the outward or inward direction.

  Moreover, it is good to provide the protrusion part which becomes the same height as the peripheral step part of the said hood body in the suitable position of a mounting plate.

  Since the opening of the mounting plate of the hood body of the present invention has a special structure as described above, even if the outer diameter of the exhaust pipe is different, the installer is installed on the outer wall in advance. If the hood body is inserted into the exhaust pipe from the outdoor direction and the opening of the mounting plate is inserted, the ridge claw at the periphery of the opening will immediately respond to the outer peripheral surface of the exhaust pipe by its elastic force. Since it will come into contact and stick so that it bites in, the ventilation equipment can be installed smoothly and reliably at the construction site, and after fitting, the hood body can be fixed loosely or dropped, etc. The phenomenon is safe because it never happens.

  In addition, the gap between the mounting plate opening and the exhaust pipe that occurs when the exhaust pipe is installed with an inclination in the outer wall from indoor to outdoor is sufficiently compensated by the elastic force of the claw around the opening. Can be securely plugged and fixed.

  By such a structure of the mounting plate of the hood body, the installation cost of the ventilation device for attaching the exhaust pipe can be greatly reduced, and the economic effect is also great.

  In addition, the mounting plate of the hood body can be fixed while maintaining the stable state of the hood body by providing a plurality of protruding portions at appropriate positions on the peripheral stepped portion and the flat surface of the hood body and closely contacting the outer wall surface. It becomes like this.

  The exhaust pipe fitted through the outer wall from the indoor to the opening of the mounting plate of the hood body responds to the outer diameter of the pipe so that the flaring claw can freely spring around and bite into the outer peripheral surface. Therefore, even if the outer diameter of the exhaust pipe is different, the installation work can be performed reliably.

  Reference numeral 1 denotes a hood body having an arbitrary shape, and a stepped portion 2 is bent in the inner direction of the peripheral edge of the hood body.

  Reference numeral 3 denotes a mounting plate fixed to an opening formed by being surrounded by the peripheral step portion 2 of the hood body 1, and this mounting plate is provided with an opening 4 having a diameter into which the exhaust pipe a is fitted.

  In the opening 4, a flange 5 that bends in the direction of the hood 1 on the outside of the mounting plate 3 is formed, and the inner peripheral edge of the opening 4 is an arcuate surface 6 having no corners.

  The flange 5 may be formed by bending in the direction of the exhaust pipe a inside the mounting plate opening 4.

  7 ··· is a protruding claw projecting obliquely outward at an appropriate interval from the flange portion 5 of the opening 4, and the protruding claw has an outer diameter dimension of the exhaust pipe a inserted into the opening 4. Even if they are different from each other, the outer peripheral surface of the exhaust pipe comes into contact with the elastic surface and is fixed so as to bite into the outer peripheral surface portion of the exhaust pipe at the stopped position.

  Further, in the case where the ridge edge 5 of the opening 4 is formed in the inner direction, the ridge claw 7... Projects directly from the opening 4 in the obliquely outer direction.

  Further, in the opening 4, it is possible to eliminate the formation of the heel edge portion in the outward or inward direction, and only to install the stripping claws 7.

  8 is a protruding portion provided at an appropriate position on the flat surface of the mounting plate 3 at the same height as the peripheral edge portion 2 of the hood body. The protruding portion and the peripheral edge portion 2 are in contact with the outer wall surface. It becomes like this.

  9 is a lattice-shaped water drop dropping plate provided on the bottom of the opening of the hood body 1, which can be opened and closed, and removes dirt, oil and fat accumulated on the inner peripheral bottom of the exhaust pipe a. For this purpose, the water drop drop plate is opened and the fingertip is inserted.

  Reference numeral 10 denotes a water flow plate having an arbitrary shape provided in the direction of the water drop dropping plate 8 at the lower end side portion of the mounting plate 3.

  Reference numeral 11 denotes a caulking portion that completely fills a gap formed between the inserted exhaust pipe a and the inner peripheral edge of the opening of the hood body mounting plate 3.
