Each manufacturing error is set within the range of A ± 0.4 [mm], B ± 0.4 [mm], C ± 0.4 [mm], and it is easy to ensure airtightness in this respect as well. It is.

  Next, an effect of maintaining airtightness by fitting the ribs of the present invention and reducing the amount of air leakage from outside the room will be described. In general, there are two possible problems due to air leakage from outside the room. The first point is to suck the air behind the ceiling. The second point is to suck air from the gap between the ceiling material for the room and the decorative panel. It is to end up. These two points will be described in detail. First, air flows from the main body inlet 6 facing the room to the heat exchanger inlet 15. At this time, the vicinity of the main body suction port 6 becomes a large negative pressure. Therefore, air is also drawn from a gap other than the opening 30 for installing the indoor filter described later on the decorative panel 5. The amount of leakage at this time is (A) the gap between the under plate 11 and the decorative panel 5, (B) the gap between the casing 14 and the indoor ceiling material 4, and (C) the indoor ceiling material 4 and the decorative panel 5. This is due to the three points. The causes of inhaling the air behind the ceiling are (A) and (B), and the causes of inhaling air from the gap between the ceiling material for the room and the decorative panel are (A) and (C). If it is achieved, the object of reducing the leakage amount can be achieved without being affected by the above (B) and (C).

  Next, the opening 30 for installing the indoor filter provided in the decorative panel 5 will be described with reference to FIG.

  FIG. 9 is a perspective view showing the decorative panel of the ventilation device according to the embodiment of the present invention from the design surface side. The decorative panel 5 is provided with an opening 30 as shown in FIG. Here, the opening 30 constitutes an exhaust port of the ventilator, and therefore, the opening 30 is hereinafter referred to as an “exhaust port 30”.

  Next, noise reduction and prevention of condensed water dripping related to the opening 30 will be described with reference to FIG.

FIG. 10 is a simplified cross-sectional view of a ventilation device according to an embodiment of the present invention.
In general, a ventilator having a heat exchange function, as shown in FIG. 10, is supplied from the outside to the inside by a supply air blower 38 and the indoor air is blown outside by an exhaust blower 39. A heat exchanger 37 having an exhaust air passage 36 and exchanging heat between the air flow flowing through the air supply air passage 35 and the exhaust air flow flowing through the exhaust air air passage 36 is provided. An outdoor filter 40 is provided, and an indoor filter 41 is provided on the inflow side of the exhaust flow. The outdoor filter 40 has a function of removing dust from the outdoors, and the indoor filter 41 has a function of removing dust from the room.

  In the ventilator according to the embodiment of the present invention, the decorative panel 5 is provided with an opening, that is, an exhaust port 30 as shown in FIG. The position of the exhaust port 30 is provided at a position shifted from the lower projection surface of the heat exchanger 37, here, at a position immediately below the outdoor filter 40. Further, the supply air passage 35 is provided with a door 50 at a portion corresponding to the exhaust port 30 of the decorative panel 5, and an outdoor filter 40 is detachably provided near the door 50, and the decorative panel 5 The size of the opening surface of the exhaust port 30 is set such that the outdoor filter 40 can be inserted and removed. There are three effects obtained from these.

  The first effect is that dew condensation water generated on the inflow side of the exhaust flow of the heat exchanger 37 does not drip into the room and contaminate the room. Condensed water generated from the heat exchanger 37 can be received when the intermediate ribs 23 provided on the decorative panel 5 serve as weirs and accumulate water, so that the condensed water does not drop into the room and stain the room. Condensed water accumulated in the decorative panel 5 is dried by the exhaust air and does not overflow.

  The second effect can be expected to be a sound insulation effect of the blowing sound emitted from the blower 39. It can be mentioned that the ventilation path composed of the blower 39, the heat exchanger 37, and the exhaust port 30 is bent, so that the blowing sound is prevented from being directly transmitted and a low-noise ventilation device is obtained.

  The third effect is that the outdoor filter 40 can be easily removed. Conventionally, removal of the outdoor filter 40 at the time of cleaning was often not possible without removing the decorative panel 5. In the ventilator according to the embodiment of the present invention, the air passage forming wall between the outdoor filter 40 and the exhaust port 30 of the decorative panel 5 is constituted by a door 50 that can be opened and closed, and the exhaust port 30 of the decorative panel 5. Since the size of the opening surface is set to a size that allows the outdoor filter 40 to be inserted and removed, the outdoor filter 40 can be easily drawn straight down.

  An indoor filter 41 is provided at the exhaust port 30 of the decorative panel 5 so as to be removable. The indoor filter 41 will be described with reference to FIGS.

FIG. 11 is an exploded perspective view of the decorative panel and the indoor filter of the ventilation device according to the embodiment of the present invention.

On the other hand, the decorative panel 5 is provided with a hook receiving portion 52 that can be engaged with the hook portion 42 of the indoor filter 41 on one side of the exhaust port 30, and can be engaged with the filter side locking portion 43 on the opposite side. The panel side locking portion 53 is provided so as to be elastically deformable, and the panel side locking portion 53 can be operated by the operation portion 60.

  The indoor filter 41 is attached to the decorative panel 5 by first inserting the hook part 42 of the indoor filter 41 into the hook receiving part 52 of the decorative panel 5 as shown by the white arrow 54 in FIG. In this state, the filter side latching portion 43 on the opposite side is rotated around the hook receiving portion 42 in the direction of the white arrow 55 in FIG. 11 until the filter side latching portion 43 engages with the panel side latching portion 53. .

FIG. 12 is an enlarged cross-sectional view showing an engagement portion between the decorative panel of the ventilation device and the indoor filter according to the embodiment of the present invention.
When the operation unit 60 is pushed, the filter side latching portion 43 and the panel side latching portion 53 are deformed in a direction to be disengaged from each other by receiving a reaction force, the engagement is released, and the indoor filter 41 is hooked by its own weight.

FIG. 14 is a schematic diagram showing a state after the disengagement operation between the decorative panel and the indoor filter of the ventilation device according to the embodiment of the present invention.
As shown in FIGS. 12 to 14, the contact angle between the filter side locking portion 43 and the panel side locking portion 53 is about 30 degrees during insertion and about 45 degrees during support after insertion. This is because the insertion of the filter side locking portion 43 can be performed with a small pressing force by providing a difference in contact angle, and the proof stress for supporting the filter side locking portion 43 can be increased. This is to prevent it from being opened only by its own weight of 41.

  The alignment mechanism of the indoor filter 41 provided on the decorative panel 25 will be described with reference to FIG.

FIG. 15 is a perspective view of the alignment mechanism portion of the indoor filter of the ventilation device according to the embodiment of the present invention.
The alignment mechanism 58 is provided on the side of the hook receiving portion 52 of the decorative panel 5 as shown in FIG. The alignment mechanism 58 absorbs the tolerance by pushing the indoor filter 41 to the center by the elastic force of the resin even when the indoor filter 41 has a larger dimension tolerance, and the indoor filter 41 is centered. Has a function to adjust. As a result, it is possible to prevent the deterioration of the design due to a slight deviation from the center.

FIG. 16 is a cross-sectional view showing the ribs of the decorative panel and the concave shape of the design surface of the ventilation device according to the embodiment of the present invention.
If the intermediate rib 23 of the decorative panel 5 is made of a synthetic resin, it is considered that sink marks are generated on the back surface. Since there is a concern about a decrease in designability of the design surface 59, a recess 70 is provided on the back surface of the intermediate rib 23 as shown in FIG.

  In addition, although the two ribs comprised of the outer rib 21 and the inner rib 22 are formed on the under plate 11 side and the intermediate rib 23 is formed on the decorative panel 5 side, an example is described here. Needless to say, these relationships may be reversed.

  In addition, here, the case where the opening of the decorative panel 5 is the exhaust port 30 has been described as an example, but it goes without saying that the opening of the decorative panel 5 can be used as an air supply port depending on the form of the air passage. Yes.
