Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a mounting device for the window insertion part of the (supply) exhaust terminal part for exhausting combustion exhaust gas to the outdoors in window-closing combustion machines, etc. be.

[Prior Art] For example, an FF type heater is equipped with an air supply/exhaust terminal component for taking in combustion air from the outdoors and discharging combustion exhaust gas to the outdoors. The air supply/exhaust terminal parts are exposed to the outdoors by passing through a wall, or are exposed to the outdoors by using the window structure of a building. Using window structures does not require drilling holes in the building itself, and is simple, so it is widely used. However, since it uses an existing window structure, it is necessary to devise a method that does not impair the original function of the window. For example, it is disclosed in Utility Model Publication No. 58-38865, and
As shown in the figure, a sliding door 4 is attached to a window frame 3.
A closing panel 9, which can be attached using the sill or lintel structure of the window frame 3, is fixed to the open area created by slightly opening one side of the sliding door 4 for the window structure that has been fitted. The air supply/exhaust terminal part 11 is inserted into the insertion hole 10 provided in the panel 9 from the indoor side and is exposed to the outdoors.

[Problems to be solved by the invention] In the installation of the above-mentioned conventional air supply/exhaust terminal component 11 of the type using a window structure, not only is a fairly long and wide blocking panel 9 required, but also a blocking panel 9 is required. In addition to the problem that a gap tends to be formed between the panel 9 and the window structure, which makes it easy for drafts to enter, the area covered by the blocking panel 9 is large, and the window itself cannot function completely. It will be severely hampered.

This idea was made to solve these conventional problems.It is easy to install, the exhaust terminal parts can be installed using the minimum necessary space in the window structure, and the sliding door can be installed when not needed. An object of the present invention is to provide a mounting device for an exhaust terminal part with good airtightness, which allows it to be evacuated to the indoor side without hindering opening, closing, and locking.

[Means for Solving the Problems] The exhaust terminal component mounting device according to this invention is designed to attach the exhaust terminal component to a slit-shaped opening between a window frame and a door frame formed by opening a door in a window structure of a building. to expose the exhaust end side to the outdoors, and close the open part of the open part other than the terminal part insertion part with a flexible closing member, and a mounting part connected to the closing member by a flexible part. This attachment part is attached to either a window frame or a door frame so that the closing member can be rotated toward the indoor side by deflection of the flexible part.

[Function] In this invention, the width of the opening between the window frame and the door frame, which is necessary for exposing the exhaust terminal part to the outside, is narrowed to about the horizontal outer diameter of the exhaust terminal part. The closing member that closes the open portion of the open portion other than the terminal component insertion portion is flexible and tightly adheres to the window structure side, so not only is there almost no gap created, but the closing member also allows the flexible portion to flex. This allows it to be rotated toward the indoor side and evacuated to a position that does not interfere with the sliding of the double sliding door.

[Embodiment] Figs. 1 to 4 all show an exhaust terminal component mounting device as an embodiment of the present invention. However, the exhaust terminal component in the illustrated example is an air supply/exhaust terminal component that also functions as a terminal component of the air supply system of the FF heater 1. As shown in FIGS. 1 and 2, the supply/exhaust terminal part 2 is configured as a double-structured pipe body, and the combustion exhaust gas is exhausted from the tip through the ventilation passage formed inside. Combustion air is supplied from the base to the combustor through a vent passage formed on the outside. This air supply/exhaust terminal part 2
Its function and basic structure are the same as the previous ones, but as clearly shown in the drawings, its shape has a distinctive shape with a longitudinally long oval or rectangular cross section. It is shaped like this.
That is, it is sandwiched between the window frame 3 and the door frame 5 in the open part between the window frame 3 of the window structure and the door frame 5 of the sliding door 4, which is created when one side of the sliding door 4 is opened. The air supply/exhaust terminal part 2 is provided, and its tip side is exposed to the outdoors.By adopting the above-mentioned shape, the opening part in the window structure can be narrow in width, and the sliding door can be formed in a generally slit shape. Just opening 4 will provide enough installation space. Therefore, the original function of the window structure (such as being able to open a sufficient area for daylighting, ventilation, etc.) is unlikely to be hindered by the shape of the air supply/exhaust terminal part 2. The open part between the window frame 3 and the door frame 5, excluding the part where the air supply/exhaust terminal part 2 is arranged, is made of flexible, heat-resistant and weather-resistant packing material such as natural rubber. A closing member 6 made of is attached, and the part is completely closed. Closing member 6
Projections 6A and grooves 6B are formed in the vertical direction, and the protrusions and grooves formed on the door frame 5 side and window frame 3 side (the example shown is a window structure made of aluminum sash, and this type of (Normally, protrusions and grooves are formed in a fairly complicated manner to improve airtightness and sound insulation), and a mounting portion 6D connected by a flexible portion 6C is integrally formed. It is attached to the door frame 5 side by fixing it to the door frame 5 with adhesive or the like. Therefore, the airtightness and watertightness between the closing member 6 and the window frame 3 and door frame 5 are extremely good, and drafts and rainwater do not enter. Furthermore, the flexibility of the flexible portion 6C can be used to rotate it toward the indoor side, and when it is not needed, it can be evacuated to a position where it does not interfere with the opening, closing, and locking of the sliding doors 4. In addition, in the installed state, since one of the sliding doors 4 is shifted, a gap is created between the sliding doors 4, but the door frame of the sliding door 4 that does not hit the closing member 6 5, the other sliding door 4
This gap is closed by attaching a sealing member 8 against the lip 7 to the surface of the glass plate.

In addition, the attachment part 6D connected by the flexible part 6C may be formed in the opposite direction to the example shown, and the attachment part 6D may be fixed to the window frame 3 side.

According to the installation device for the air supply/exhaust terminal part 2 of this example, the opening dimension of the window structure required for installing the air supply/exhaust terminal part 2 can be made extremely small, 20 to 30 mm, and the window structure It hardly interferes with the functions of the device, has good airtightness and watertightness, and is easy to install. When not needed, the closing member 6 can be evacuated by bending the flexible portion 6C to the indoor side where it does not interfere with the opening/closing of the sliding door 4, and the opening/closing and locking of the sliding door 4 can be completely prevented. It is convenient because it can be carried out at any time.

[Effects of the invention] As is clear from the above description of the embodiments, the exhaust terminal component mounting device of the present invention is capable of attaching the exhaust terminal component between the window frame and the door frame formed by opening the door in the window structure of a building. The exhaust end side is exposed to the outdoors by passing through the slit-shaped opening part, and the open part other than the terminal part insertion part of the opening part is closed with a flexible closing member. A mounting part is provided, and this mounting part is attached to either a window frame or a door frame so that the closing member can be rotated toward the indoor side by bending the flexible part. The width of the opening between the window frame and the door frame, which is necessary for exposing the terminal component to the outside, is narrowed to about the horizontal outer diameter of the exhaust terminal component, and the terminal component insertion point in the opening is reduced. The closing member that closes the other open parts is flexible and tightly adheres to the window structure side, so not only does it almost eliminate the formation of gaps, but also the closing member can be rotated toward the indoor side by bending the flexible part and pulled. It can also be evacuated to a position that does not interfere with the sliding of the sliding door. Therefore, it is easy to install, and the exhaust terminal parts can be installed using the minimum necessary space in the window structure, and when not needed, they can be evacuated to the indoor side where it does not interfere with opening, closing, and locking the sliding doors. This provides a mounting device for exhaust terminal parts with good airtightness.
