Another kind of security between a panel and a second panel Install the schematic.

The present invention illustrates the structure of the present invention by taking a heating ventilating fan as an example, but is not limited to a heating ventilating fan.

2A is a schematic view of the entire ventilating fan of the present invention; FIG. 2B is a transverse cross-sectional view of FIG. 2A; and FIGS. 3A and 3B are schematic views showing the installation of the first panel and the control panel of the ventilating fan of the present invention, but the second panel is not closed.

As shown in FIG. 2A, FIG. 2B, and FIG. 3A, a ventilating fan 10 includes: a box 12 having a flange 11 on the side of the box, a panel 20 at the box mouth, and a fan 13 installed in the box 12, The panel 20 is composed of a first panel 30 provided with a first air inlet 31 and a first air outlet 32, and a second panel 40 mounted below the first panel 30. The air passes through the first panel 30 and the second panel 40. After the gap 50 between the two, the tank 12 is entered through the first air inlet 31.

The first panel 30 is recessed toward the inside of the casing 12, that is, the surface of the first panel 30 is a recessed structure that is recessed upwardly facing the casing 12, and the first air inlet 31 and the edge of the first panel 30 are formed. An inclined portion 37 is formed between 33, 34, 35, and 36. The edge portion refers to an edge portion of the periphery of the first panel 30, that is, a rhombic edge that intersects the inclined portion 37.

A second air outlet 42 is disposed on the second panel 40 at a position corresponding to the first air outlet 32 of the first panel 30. The first air outlet 32 and the second air outlet 42 are extended in a tubular shape. The wall forms an air passage 321 . The air outlet passage 321 formed by the air through the first air outlet 32 and the second air outlet 42 is blown out from the casing 12.

In the present embodiment, the heating element 60 is also mounted in the casing 12, and is a heating ventilating fan having a circulating air blowing mode for circulating indoor air and a heating mode for heating the indoor air. The first air inlet 31 and the first air outlet 32 of the first panel 30 are both rectangular and juxtaposed in the width direction. The second air outlet 42 accommodates the rotatable air outlet 38 disposed on the air outlet 321 . When the heating ventilator does not open the air outlet 38, the outer surface of the air outlet 38 and the outer surface of the second panel 40 are kept flat.

With the above configuration, when the heating ventilation fan is operated, the indoor air enters the first air inlet 31 of the first panel 30 from the gap 50 between the first panel 30 and the second panel 40, as opposed to the second panel 40. The face of a panel 30 is recessed toward the interior of the casing 12 to form an inclined portion 37. Therefore, when the air is intended to enter the first air inlet 31 of the first panel 30, the inclined portion 37 has a guiding effect and can be smoothly smoothed. The sliding guide is guided into the first air inlet 31, so that the air intake amount and the noise can be improved.

Moreover, since the second panel 40 is mounted below the first panel 30 and the first panel 30 is recessed upwardly, when the second panel 40 is mounted under the first panel 30, the overall thickness of the panel 20 is thinned. When the panel 20 fixed in one body is attached to the casing 12 and mounted to the ceiling, its thickness protruding from the ceiling is thinned, making it more beautiful.

Due to the air outlet route of the air (via the first air outlet 32 and the second air outlet 42) and the air entering the air intake path of the casing 12 (via the gap 50 and the first air inlet 31), the first air outlet 32 and the second The cylindrical walls of the air outlet passages 321 between the air outlets 42 are separated, so that the air entering and leaving the casing 12 is not mixed.

Next, on the basis of the above embodiment, as shown in FIGS. 4A and 4B, a protruding rib 44 surrounding the first air inlet 31 is provided on the back surface 43 of the second panel 40, and the protruding rib 44 and the first The gap 50 is formed between the panels 30.

A portion of the protruding rib 44 is located opposite the inclined portion 37 of the first panel 30, that is, the front projection of the protruding rib 44 of the portion falls in the inclined portion 37; the other portion is located at the opposite first air inlet 31. At the position between the first air outlet 32 and the first air outlet 32, the front projection of the protruding rib 44 of the portion falls between the first air inlet 31 and the first air outlet 32. Thus, the area of the annular shape surrounded by the protruding ribs 44 is necessarily equal to or larger than the area of the first air inlet 31.

As explained above, the first air outlet 32 on the first panel 30 and the second air outlet 42 on the second panel 40 are connected by the air outlet passage 321. Therefore, the "projecting rib 44 around the first air inlet 31" according to the present invention includes two cases, or the protruding air rib 44 independently surrounds the first air inlet 31, or the above-mentioned cylindrical wall by the air passage 321 The first air inlets 31 are collectively separated from the first air outlet 32.

In the present embodiment, since the first air inlet 31 and the first air outlet 32 are both rectangular, the protruding ribs 44 also form an annular shape.

When the heating ventilation fan is running, the motor generates noise due to the high-speed rotation, and the noise is first transmitted to the first panel 30 and the second panel 40 through the first air inlet 31 on the first panel 30, and then transmitted from the gap 50. Go indoors.

Since the protruding rib 44 is protruding from the back surface of the second panel 40 43 Therefore, a semi-enclosed space is formed between the first panel 30 and the second panel 40 (only a space is provided on the surface opposite to the air inlet), and the space hinders and absorbs the noise, so that the noise It is directly difficult to pass into the room from the gap 50 formed between the first panel 30 and the second panel 40, that is, noise can be blocked from propagating into the room.

In addition, the provision of the protruding ribs 44 on the back surface 43 of the second panel 40 also has the effect of increasing the strength of the second panel 40.

Further, as shown in FIGS. 4A and 4B, a rectifying member 45 is provided inside the annular protruding rib 44 on the back surface 43 of the second panel 40. In this embodiment, the first air inlet 31 is rectangular, and the rectifying member 45 is a plurality of fairings 451, 452, 453, 454, 455 parallel to the long side of the first air inlet 31, and a part of the fairing The height of 451, 453, 455 is higher than the height of the protruding ribs 44, wherein the height of the partial fairings 452, 454 is lower than the height of the protruding ribs 44, and the height of the integral fairings is wavy. Since the commutator segments are alternately changed in height, interference occurs when noise transmitted from the first air inlet port 31 passes through the plurality of segments, so that noise can be reduced.

The fairing pieces 451, 452, 453, 454, and 455 are inclined toward the inclined portion 37 on the long side of the first air inlet 31. The "tilt" means that the tip end of the commutator piece is biased toward the edge portion 33 so as to be closer to the inclined portion 37.

The rectifying member 45 of the present invention may also be in the shape of a plurality of tapers such as a conical shape, a triangular pyramid shape or a quadrangular pyramid shape. It can also be a number of coaxial annular ribs.

In addition, in the following description of the present invention, the second panel is The structure mounted on the first panel 30 is described centrally, so that the protruding ribs 44 are not necessary.

As shown in FIG. 3A and FIG. 3B, a movable member 80 and a fixing member 70 are formed between the first panel 30 and the second panel 40, so that the second panel 40 is detachably mounted under the first panel 30. . The fixing member 70 is composed of a column 73 disposed on the first panel 30 and a column 74 disposed on the second panel 40.
