2. Description of the Related Art From a cooking appliance for performing various types of cooking, oily smoke rises when baked goods are produced, and steam rises when cooking is cooked. If the cooking appliance burns gas, These also include exhaust gas. These are collectively referred to as exhaust gas below, and this exhaust gas must be exhausted outdoors early. Although the exhaust gas may be exhausted by a ventilation fan mounted on a wall, in recent years, a hood for collecting the exhaust gas has been arranged on a cooking device, and the exhaust gas has been discharged from the hood through an exhaust duct. Emissions are being made to the outside.

A conventional example of such a lens hood is shown in FIG. In the lamp hood shown in FIG. 10, exhaust gas is taken in from above a straightening plate attached to the wall side at an inclination angle of 45 °, and is exhausted to the outside via an exhaust duct by a fan arranged on the rear side of the straightening plate. It was made. In such a lamp hood, it is considered that the exhaust gas can be collected by a natural flow by the 45 ° inclined straightening plate serving as the front panel, but the storage space for the fan is located behind the straightening plate. The position of the exhaust duct to be connected to the fan is limited and there is no room for selection and adjustment.

By the way, in recent years, especially in apartment buildings, beams of the building may protrude into the room. On the other hand, according to the Fire Service Law, it is necessary to secure 80 cm above the upper surface of the cooking device to the lower surface of the lamp hood. It is not supposed to be. In that case, if the beam is exposed in the room, the lamp hood must be installed avoiding the beam, so that 80 mm is required between the lens hood and the cooking device.
cm or more cannot be secured. In particular, in the lamp hood shown in FIG. 10, the exhaust duct to be connected to the fan cannot be installed because it is obstructed by the beam.

Accordingly, a range hood as shown in FIG. 11 has been developed. In the lamp hood of FIG. 11, the opening is made horizontal, and the exhaust duct is hidden on the rear side by a decorative plate integrated with the front part of the upper surface. Then, in this lamp hood, as shown in FIG. 12 (a), when there is a building beam at the upper right of the drawing, the exhaust duct is connected to the left side of the drawing,
As shown in (b) of FIG. 12, when the beam is on the upper rear side of the lamp hood, the exhaust duct is connected to the front side of the lamp hood, and any exhaust duct is hidden by a decorative plate. is there. Of course, when the beam is present on the left side, the exhaust duct is connected to the right side in the figure, contrary to the one shown in FIG. 12A, and the fan in the lamp hood determines the position of the outlet. It is changed and stored.

[0007] The lamp hood of the type shown in FIG. 11 can be installed within a certain allowable range even if a beam is present. It is easy to do. However, to the extent that the connection of the exhaust duct can be changed to the left or right, this kind of lens hood cannot be installed according to all housing conditions, and it is the current situation that further flexibility is required. is there.

The inventor of the present invention has conducted various studies on how to install the lens hood with a wide degree of freedom, and as a result, completed the present invention.

[0008]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above situation, and a problem to be solved is to install a lamp hood even when a beam is exposed in a room. The goal is to be able to do this while being fully adapted to the current situation.

That is, the object of the present invention is to

An object of the present invention is to provide a lens hood unit having a simple configuration, which can perform fine adjustment of connection and has excellent versatility in installation.

[0010]

Means for Solving the Problems To solve the above problems, the means adopted by the present invention will be described with reference numerals in the description of the embodiment. A hood 10 for collecting exhaust gas containing oil smoke and water vapor generated from the hood, a fan 20 forcibly sending the exhaust gas collected by the hood 10 to the outside, and the hood 10 A lens hood unit 100 including a fan box 30 forming a ventilation path between ducts 80, wherein the lens hood 10 has a ventilation opening 13 substantially at the center of a rear portion of an upper surface thereof. It is assumed that the fan box 30 has a mounting wall 14 erected on the rear peripheral edge and fixed to a building wall 210 or the like. A first opening 31 communicating with the ventilation opening 13 on the lamp hood 10 side, a second opening 32 formed on the upper surface thereof and connected to the exhaust port 21 of the fan 20, and a rear surface formed on the rear surface thereof. The fan 2 has a third opening 33 sealed by a partition plate 34.
0 is attached to the mounting portion 35 of the fan box 30.
Alternatively, the lens-hood unit 100 is characterized by being fixed to the mounting wall 14 side.

That is, the lens hood unit 10
0 is a lamp hood 10 for collecting exhaust gas,
The fan box 30 which is attached to the upper surface of the lens hood 10 and communicates with the lens hood 10.
And a fan 20 housed in the fan box 30 for forcibly exhausting exhaust gas through an exhaust duct 80, and these are unitized.
In other words, by mounting the fan box 30 on the top plate 12 of the lens hood 10, the lens hood unit 100 forms a closed air passage that communicates with the ventilation opening 13 on the lens hood 10. The fan 20 is housed in the air passage and its exhaust port 2
1 communicates from the second opening 32 or the third opening 33 of the fan box 30 to the exhaust duct 80 side.

According to the lens hood unit 100 of the present invention configured as described above, the mounting position of the fan box 30 on the mounting wall 14 is adjusted, or the mounting position of the fan 20 on the fan box 30 or the mounting wall 14 is adjusted. By adjusting, the exhaust port 2 of the fan 20 can be adjusted.
1 position, in other words, the lens / hood unit 10
Thus, the mounting position of the exhaust duct 80 with respect to zero can be freely adjusted. This adjustable point is specifically described as follows.

FIG. 3 shows an example in which the exhaust duct 80 is mounted at the center of the rear end of the lens hood unit 100. In this case, the fan 20
Is attached to the fan box 30 side as shown in FIG.
As shown in FIG. 3, the fan box 30 is mounted on the top plate 12 and the front side with the second opening 32 positioned rearward. Of course, in this case,
The third opening 33 shown in FIG. 6 is on the front side,
The third opening 33 is covered by the fan box 30.

Accordingly, the lens / hood unit 1
7 is in a state of a positional relationship as shown in FIG. 7, and as shown in FIG.
It is possible to cope with the case where the exhaust duct 80 exists on the side of 00. Also, the exhaust port 2 of the fan 20
1, the duct connection adapter 40 is connected, and the duct connection adapter 40 is connected to the exhaust duct 80. By variously selecting the duct connection adapter 40, the exhaust direction from the lamp hood unit 100 can be changed. 2 can be dealt with.

On the other hand, as shown in FIG. 9B, when the beam 220 exists in the horizontal direction above the rear part of the lamp hood unit 100, the exhaust duct 80 is connected to the fan box 30. In this case, the fan box 30 in the state shown in FIG. 3 is employed in a left-right inverted manner, or a top plate having the second opening 32 formed therein is installed in a right-left inverted manner. The fan box 30 is adopted. Thereby, FIG. 4 or FIG.

The exhaust gas can be discharged by the exhaust duct 80 in the direction shown in FIG.

As shown in FIG. 9C, if a wall opening 211 through which the exhaust duct 80 passes is present or can be formed, the fan box 30 is replaced with the fan box 30 shown in FIG.
From the state shown in FIG. 8 to the state shown in FIG.
It is fixed on the top plate 12 of the lens hood 10 by rotating it by 0 °. Also in this case, since the inside of the fan box 30 and the interior of the lamp hood 10 must be communicated with each other, the partition plate 34 that has closed the third opening 33 is removed, and the first opening that has been opened to the ventilation opening 13 until then is removed. Opening 3
1 is closed by the partition plate 34. The above work is
Since it is only necessary to change the mounting position of the partition plate 34 and the mounting position of the fan box 30 itself to the lamp hood 10, it is not only very easy to perform, but also it is not particularly necessary to separately process the lamp hood unit 100. Therefore, the versatility of the lens / hood unit 100 is increasing.

In any of the above cases, the exhaust port 21 of the fan 20 is described separately from being located substantially at the center of the hood frame main body 11. In some cases, the user wants to shift in the left-right direction. In that case, first, the hood 10 of the fan box 30
It is sufficient to shift the mounting position with respect to right and left. For this purpose, the ventilation opening 13 on the hood 10 side is connected to the second opening 32 or the third opening 33 on the fan box 30 side.
Smaller than the fan box 3
Communication between 0 and the lens hood 10 is through the fan box 30
Can be sufficiently performed by shifting the right and left. Of course, FIG.
As shown in FIG. 7, the mounting portion 35 of the fan box 30 on which the mounting base 22 of the fan 20 is to be mounted is provided with the mounting hole as the elongated hole 36 in the horizontal direction as shown in FIG. The adjustment can also be performed by adjusting the mounting position of the fan 20 itself.

In the lens hood unit 100 of the present invention, the mounting wall 14 integrated with the lens hood 10 is
Since the mounting bracket 60 is fixed to the wall 210 of the building and the fan 20 is mainly mounted on the fan box 30, the lamp hood unit 1
00 can be firmly attached to the wall 210. In particular, the fact that the mounting wall 14 is formed in a substantially U-shape in plan view is one reason that the flat shape is larger than the thickness and that the lens hood 10 that supports the fan 20 can be firmly fixed to the wall 210 side. It is also with.

By the way, in this kind of lens hood unit 100, it is important that the exhaust function of the exhaust gas collected by the lens hood 10 is not impaired by changing the position of the exhaust port 21 of the fan 20. In the lamp hood unit 100 of the present invention, the fan box 30 forms an air passage that connects the inside of the hood frame body 11 and the exhaust duct 80, and the fan 20 is arranged in the air passage. So there is no such fear. This is because a closed air passage through which the exhaust gas is actively sent by the fan box 30 is formed, and the volume of the exhaust gas, that is, the air passage, This is because the volume and shape hardly change.

In the lamp hood unit 100 of the embodiment described below, the curtain plate 52 is attached to the front side of the fan box 30.
No matter what position the 0 is attached to, there is no change in the form seen from the front or the like, and there is no change in the design of the entire hood unit 100. Further, the oil contained in the exhaust gas accumulates in the fan 20, and the oil must be periodically discharged. Since the wall openings 211 are formed in two directions, the accumulated oil can be efficiently used by the fan 2 regardless of whether it is used in FIG. 8A or FIG.
It can be discharged out of zero.

Further, the plate located above the first opening 31 of the fan box 30 in the drawing may be attached to and detached from the main body, and may be fixed to the main body by turning the right and left over. The second opening 32 for connecting the exhaust port 21 of the fan 20 is formed. In the embodiment shown in FIG. 6, the upper plate in the drawing is integrated with the second opening 32 being shifted toward the front side (the left side in the drawing). A reinforcement portion is formed.

A third opening 33 is formed in the wall plate on the right side of the fan box 30 in the drawing, and when this 0 is arranged in the state shown in FIG.
Is covered by a partition plate 34. In FIG. 6, two partition plates 34 are drawn, but only one is actually used as follows. Also, as shown in FIG. 9C, for example, when the exhaust duct 80 is directly taken out of the wall opening 211 of the wall 210 as shown in FIG. Can be used to mount the mounting base 22 on the front side of the mounting wall 14 by exposing the mounting base 22 to the fan box 30. In this case, a rear opening 14a is formed in the mounting wall 14 on the side of the lamp hood 10. It is good to keep.

The position of the second opening 32 in the fan box 30 depends on the position of the fan 2 connected thereto.
The position of the exhaust port 21 of 0, in other words, the position of the exhaust duct 80 is to be determined.
