Description

[Detailed description of the invention] This invention relates to the improvement of a weather cover used in a simultaneous intake/exhaust type ventilation fan, and in particular, the tip of the weather cover is connected to a double-layered intake/exhaust pipe for indoor ventilation inserted into the outer wall. This design has been devised so that the forming process of the joint part of the weather cover can be easily performed.

Figures 1 and 2 are diagrams showing the appearance of a weather cover used in a conventional simultaneous intake/exhaust type ventilation fan and how it is installed and used. The front weather cover body is divided into path A and exhaust path B, 3 is an integrally molded intake/exhaust partition window plate that covers the rear opening of this cover body, and the center has the above-mentioned intake/exhaust paths A and B. An intake pipe a and an exhaust pipe b each having a symmetrical half-moon shape and communicating with each other are provided to protrude outside the window panel.
Reference numeral 5 denotes an outer wall that separates indoor and outdoor areas, and 6 indicates a two-layer intake/exhaust pipe for indoor ventilation inserted through this outer wall.A central partition wall 7 has symmetrical half-moon-shaped intake passages 6a and exhaust passages 6b on both sides thereof. When the weather cover consisting of the cover body and the intake/exhaust partition plate is installed, the half-moon-shaped intake/exhaust pipes a and b are fitted and inserted as shown in Fig. 2 A and B, respectively, thereby forming an indoor/outdoor communication intake/exhaust passage. Also, 8 in the figure is 2 above.
This figure shows an indoor simultaneous intake/exhaust type ventilation fan body with a layered pipe 6 protruding from it.

In the conventional system, as described above, the indoor side ventilation fan body and the indoor side weather cover are constructed using two identically shaped pipes protruding from the air intake/exhaust partition window plate 3 on the two-layer pipe 6 inserted through the outer wall 5. Since the half-moon-shaped intake and exhaust pipes a and b are inserted to communicate indoor and outdoor, not only does the mold for the weather cover become extremely complicated, but
There was an inconvenience in that the mounting position of the weather cover required extreme accuracy and the installation work required a high degree of skill.

This invention is aimed at eliminating such drawbacks and inconveniences, and one embodiment of the weather cover attaching device of this invention will be described below. That is, in FIGS. 3 and 4, the same parts as those in FIGS. 1 and 2 are indicated by the same reference numerals, but the intake/exhaust partition window plate 3 in this case is made of a single plate, and has a central recess. A pair of rectangular intake/exhaust window holes 3c and 3d on the left and right sides are provided in the bottom wall 3b of the portion 3a. 9 has an L-shaped cross section as shown in FIG. The above-mentioned concave portion 3
The partition plate inside a has suction/exhaust recesses A ₁ , B ₁ including the above-mentioned suction/exhaust window holes 3 c , 3 d on both sides thereof. 10 is a rising wall 9b of the partition plate 9
An L-shaped locking piece is overlaid and fixed on one side, and between the inner side and the outer side of the rising wall 9b is a central partition for a two-layer ventilation intake/exhaust pipe 6 inserted through the outer wall 5. Gap 1 set to width d to insert and hold wall 7
1 is formed as shown in FIG.

FIG. 4 is a diagram showing how the weather cover of the present invention, which consists of the intake/exhaust partition window plate 3 with a partition plate and the weather cover main body 1, is installed and used. However, the air intake and exhaust air holes formed in the central concave portion 3a of the air intake and exhaust partition window plate 3 are
The intake/exhaust passages 6a, 6b are inserted into the exhaust recesses _A1 , _B1 in the state shown in the figure while being guided by the central partition plate 9, and are formed by the central partition wall 7 of the two-layer pipe.
are connected to the air intake/exhaust passages A, inside the weather cover main body 1 via the air intake/exhaust window holes 3c, 3d on the front, respectively.
It is connected to B. In this connected state, the rising wall 9b of the partition plate 9 is inserted into one intake passage 6a of the two-layer pipe 6 as shown in FIG. The locking piece 10 is inserted, and the tip of the central partition wall 7 of the two-layer pipe 6 is inserted and held between the rising wall 9b of the partition plate 9 and the locking piece 10, whereby the two-layer pipe 6
The insertion end is positioned.

Incidentally, the inclined surfaces 9c provided above and below the above-mentioned rising wall 9
serves as a guide during insertion.

As described above, the weather cover mounting device of this invention consists of the intake/exhaust partition window plate made of a single plate separate from the weather cover main body, and utilizes the concave part formed by press processing etc. on this single plate and the central partition plate. Since the two-layer pipe for ventilation is connected to this part, not only is it extremely easy to mold the entire weather cover, but the installation position of the weather cover is also relatively flexible. This has the advantage that installation work can be carried out appropriately and quickly at any location. In addition, the tip of the center partition wall of the two-layer intake/exhaust pipe overlaps the partition plate of the intake/exhaust partition plate, and is inserted and held between this and the locking piece, so that the two-layer intake/exhaust pipe and the weather cover body It also has the effect of making it extremely easy to determine the mounting position.
