  The L-shaped metal fitting 3 is made of a metal material, and is a mounting part for mounting the ventilating fan main body 20 to the installation wall 4. As shown in FIG. 2 and FIG. 3, in the L-shaped member, the L-shaped bracket 3 is a first attachment portion 3 a which is a portion on one end side across the L-shaped bent portion, and an L-shaped bent portion And a second mounting portion 3b which is a portion on the other end side, and has a shape bent at a right angle to the L-shaped cross-sectional shape. The first attachment portion 3a and the second attachment portion 3b are connected at a bending portion which is a bending portion of an L-shape. The L-shaped metal fitting 3 is disposed at the upper left and right ends of the exhaust fan 2. That is, the L-shaped metal fitting 3 is an area where the upper surface plate 2 d and the protruding portion 2 e intersect and contact to form an L shape, and in the left and right end regions of the upper surface plate 2 d of the exhaust blower 2 and the protruding portion 2 e Be placed.

  The first attachment portion 3a of the L-shaped metal fitting 3 is locked to the top plate 2d of the exhaust blower 2 by a fastening member such as a screw or a bolt. Metal fitting side first mounting hole which is a circular through hole through which a screw for mounting the L-shaped metal fitting 3 to the upper surface plate 2 d of the exhaust blower 2 is inserted as a metal fitting side mounting hole in the first mounting portion 3 a of the L-shaped metal fitting 3 Two 3c are formed. The first metal fitting side mounting hole 3c is aligned with a screw hole (not shown) formed on the upper surface plate 2d of the exhaust blower 2 for passing a screw for attaching the L-shaped metal fitting 3 to the upper surface plate 2d of the exhaust blower 2. It is formed.

  The second attachment portion 3 b of the L-shaped metal fitting 3 is locked to the installation wall 4 together with the back plate 2 a of the exhaust fan 2 by a fastening member such as a screw. In the second mounting portion 3b of the L-shaped metal fitting 3, a metal-fitting-side second mounting hole is provided as a metal fitting side mounting hole, through which a screw for attaching the L-shaped metal fitting 3 to the installation wall 4 together with the back plate 2a of the exhaust fan 2 is inserted. An attachment hole 3d is formed. The metal fitting side second mounting hole 3d is at the position of the exhaust fan side mounting hole 5a formed in the projecting portion 2e for passing a screw for attaching the L-shaped metal fitting 3 to the installation wall 4 together with the back plate 2a of the exhaust fan 2. Together, the major axis direction is the left and right direction, and it is made into the long hole formed.

  The exhaust fan side mounting holes 5a provided in the left end region and the right end region of the protrusion 2e may be provided at asymmetric positions in the left-right direction. Even in this case, when the L-shaped metal fitting 3 is arranged in the region on the left end portion side and the region on the right end portion side of the protrusion 2 e by making the metal fitting side second attachment hole 3 d long, the left end portion side and It can be used on both the right end side. Thereby, the L-shaped metal fitting 3 disposed in the area on the left end side of the protruding portion 2 e and the L-shaped metal fitting 3 disposed in the area on the right end side of the protruding portion 2 e are made common as one component. It is possible to reduce the load of component production and to reduce the cost.

  Further, as shown in FIG. 2 and FIG. 3, the L-shaped metal fitting 3 is provided with a triangular rib 3 e around a bent portion which is a connection portion between the first attachment portion 3 a and the second attachment portion 3 b. . The triangular rib 3e has a triangular shape in a side view of the L-shaped metal fitting 3, and is formed in a region extending from the first attachment portion 3a to the second attachment portion 3b adjacent to each other across the L-shaped bent portion It is done. The triangular rib 3e functions as a strength reinforcing portion that reinforces the strength of the bent portion of the L-shaped metal fitting 3. By providing the triangular rib 3e, the strength of the bent portion of the L-shaped metal fitting 3 is improved. Thereby, when obtaining the L-shaped metal fitting 3 in which the bent portion has a desired strength, it is possible to reduce the thickness of the L-shaped metal fitting 3 and achieve weight reduction and cost reduction of the L-shaped metal fitting 3.

  As described above, when the ventilation fan 100 is installed on the installation wall 4, the first mounting portion 3 a of the L-shaped metal fitting 3 is locked to the top plate 2 d of the exhaust fan 2 by a screw. In addition, the second attachment portion 3b of the L-shaped metal fitting 3 is locked to the installation wall 4 together with the projection 2e of the back plate 2a by a screw. That is, in the ventilation fan 100, the second attachment portion 3 b of the L-shaped metal fitting 3 and the projection 2 e of the back plate 2 a are both fastened to the installation wall 4 using attachment screws and fixed to the installation wall 4. Thereby, when the ventilation fan 100 is installed on the installation wall 4, the load associated with the weight of the ventilation fan 100 concentrates on the L-shaped bracket 3 to suppress and prevent the front side of the ventilation fan 100 from hanging down and tilting. can do.

  The ventilation fan does not have the projection 2e, and the second attachment 3b of the L-shaped metal fitting 3 and the projection 2e of the back plate 2a are both fastened to the installation wall 4 using attachment screws and not fixed to the installation wall 4 In this case, only the L-shaped bracket 3 will support the weight of the ventilation fan. In this case, depending on conditions such as the shape of the ventilating fan, the weight of the ventilating fan, and the size of the L-shaped bracket 3, the front side of the ventilating fan main body 20 is on the lower side The problem of hanging down and tilting may occur. In particular, when the product height of the ventilating fan is small, the front side of the ventilating fan tends to hang downward. The product height is the height dimension of the ventilating fan main body 20 when installed on the installation wall 4 and is the thickness dimension of the ventilating fan main body 20 in the vertical direction. For this reason, in order to strengthen the lock between the L-shaped metal fitting 3 and the ventilation fan, it is necessary to enlarge the L-shaped metal fitting 3 or to increase the number of L-shaped metal fittings 3 and the weight and cost of the ventilation fan increase. .

  On the other hand, in the ventilation fan 100, the second attachment portion 3 b of the L-shaped metal fitting 3 and the projection 2 e of the back plate 2 a are both fastened to the installation wall 4 using attachment screws and fixed to the installation wall 4. By co-tightening the L-shaped bracket 3 and the back plate 2a, the load caused by the weight of the ventilation fan 100 is dispersed to the back plate 2a constituting the exhaust fan 2 and the L-shaped bracket 3, and the weight of the ventilation fan 100 It is prevented that the load resulting from is concentrated on the L-shaped bracket 3. Thus, the ventilation fan 100 does not have a complicated structure for installation on the installation wall 4 and has a desired configuration, that is, a direction in which the top surface 1a of the hood 1 and the top plate 2d are parallel to the horizontal direction. Is held in the position where it is held, and sagging to the lower side of the front side of the ventilating fan main body 20 is suppressed and prevented.

  This makes it possible to reduce the size of the L-shaped metal fitting 3, to reduce the weight of the L-shaped metal fitting 3, and to simplify the engagement between the L-shaped metal fitting 3 and the exhaust fan 2. In order to simplify the engagement between the L-shaped metal fitting 3 and the exhaust blower 2, the number of screws for fixing the L-shaped metal fitting 3 and the exhaust blower 2 may be reduced, and the size of the screw may be reduced. It can be mentioned.

  Further, the protrusion 2e is not provided only in the co-clamped portion to be co-fastened with the L-shaped metal fitting 3, but in the entire width in the left-right direction, the protrusion 2e protrudes upward from the upper surface plate 2d. That is, due to the weight of the ventilation fan 100, the protrusion 2e is provided in the entire width in the left-right direction in the back plate 2a, with the width in the left-right direction of the protrusion 2e being the same width below the top plate 2d in the back plate 2a. The effect of dispersing the load on the protrusion 2e is improved. Thereby, the ventilation fan 100 can be more firmly fixed to the installation wall 4 compared with the case where the protrusion 2e is provided only in the joint tightening portion in the left-right direction in the back plate 2a. Moreover, the process for forming the protrusion part 2e of the shape which one part protruded is unnecessary, and manufacture of the backplate 2a becomes easy.

  Further, by arranging the L-shaped metal fitting 3 on both end sides in the left-right direction of the top plate 2d and the projecting part 2e of the exhaust fan 2, an effect of dispersing the load caused by the weight of the ventilation fan 100 to the projecting part 2e It is obtained equally.

Below, the method to install the ventilation fan 100 in the installation wall 4 is demonstrated with reference to FIG.
In order to install the ventilation fan 100 on the installation wall 4, first, the L-shaped metal fitting 3 is screwed to the top plate 2 d of the exhaust fan 2 in the ventilation fan main body 20 in the arrangement shown in FIG. 3, for example. Next, a screw (not shown) is temporarily fixed at a predetermined position on the installation wall 4. Next, a screw temporarily fixed to the installation wall 4 is inserted into the dharma hole 6, and the ventilation fan 100 is hooked on the screw. Thus, the ventilation fan 100 is disposed at a predetermined installation position on the installation wall 4.

  Next, the exhaust blower side mounting holes 5a provided at two places and the hood side mounting holes 5b provided at two places are locked using the washer 21 and the screw 22. At this time, in the exhaust blower side attachment hole 5a, the second attachment portion 3b of the L-shaped metal fitting 3 and the projection 2e of the exhaust blower 2 are fastened together to the installation wall 4 by the screws 22 and fixed. Further, the duct connection port 7 is connected to an external opening (not shown) provided on the outer wall of the building and in communication with the outside of the building by a duct (not shown). The ventilation fan 100 can be fixed to the installation wall 4 by performing the above processing.

  In the installation work to the installation wall 4 of the ventilation fan 100 mentioned above, since the fixing structure to the installation wall 4 of the ventilation fan 100 is simple, installation work is easy.

  Further, as shown in FIG. 5, the ventilation fan 100 is mounted on the front curtain 8 attached to the front surface 1 b of the hood 1 on the top surface 1 a of the hood 1 so as to hide the exhaust blower 2 and the duct portion not shown. And a transverse blade plate 9 attached to the side surface 1c side of the hood 1 on the upper surface 1a of FIG. 5 is a schematic view showing the ventilation fan 100 according to the first embodiment of the present invention, and is a perspective view showing the installation positions of the front curtain plate 8 and the horizontal curtain plate 9.

  Here, the reason why the front curtain plate 8 and the horizontal curtain plate 9 are provided is that the components such as the exhaust blower 2, the duct connection port 7 and the duct portion are exposed to the outside only by installing the ventilating fan main body on the kitchen wall. This is because the metal base is often left as it is not good in design and appearance, and it is necessary to hide them. For this reason, the front curtain plate 8 and the horizontal curtain plate 9 which are painted in the same color as the hood 1 or the color according to the design of the installation wall 4 or the hanging cupboard are attached so as to hide the exhaust blower 2 and the duct portion To ensure that the design and appearance, and harmony with the equipment, etc.

  In addition, since the exhaust fan 2 is hidden by the front curtain plate 8 and the horizontal curtain plate 9, there is no problem that the design of the ventilation fan 100 is reduced by the attachment of the L-shaped metal fitting 3.

  By the way, although a ventilation fan attached to the kitchen is mainly a ventilation fan with a hood width of 600 mm, according to the Fire Prevention Ordinance, the structure around the stove is at least 15 centimeters between the stove and combustible articles And the width of the stove is set to 600 mm or less. FIG. 6 is a perspective view showing an example of a ventilation fan having a hood width dimension of 600 mm.

  Since the ventilation fan attached to the kitchen needs to cover the stove uniformly, if there is a flammable wall on only one side, a hood with a hood width dimension of 750 mm, if there is a flammable wall on both sides, the hood width It is necessary to select a hood fan with a size of 900 mm. Therefore, in addition to the hood having a hood width of 600 mm as shown in FIG. 6, the one having a hood width of 750 mm as shown in FIG. 1 and the one not shown having a hood width of 900 mm is a standard model. Is common.

  Among the plurality of types of widths of the hood 1, by sharing the exhaust fan 2, the L-shaped metal fitting 3 can also be shared, and the method of attaching the ventilation fan 100 can also be unified.

  Further, even if the exhaust blower 2 is made common, the hood 1 having a hood width dimension of 750 mm can be provided by providing a lateral curtain plate fixing bracket for temporarily fixing the lateral curtain plate 9 between the exhaust blower 2 and the lateral curtain plate 9. The hood 1 having a hood width dimension of 900 mm can be handled by a similar-shaped transverse plate 9. In the case where the exhaust fan 2 of the ventilation fan 100 is made common, the hood width dimension is not limited to 600 mm, 750 mm or 900 mm.

  In the case of a wide model, that is, a model having a hood width dimension of 750 mm and a model having a hood width dimension of 900 mm, as shown in FIG. 1, the external shape of the front plate 2b constituting the outer shell of the exhaust blower 2 The trapezoid shape is engaged with the hood 1 to reduce the weight of the ventilation fan and to suppress the tilt of the hood 1. In addition to reducing the weight and material cost of the ventilation fan by making the side plate 2c into a trapezoidal shape instead of a rectangular shape, it is also possible to reduce an angular region to prevent injury to workers during installation. it can.

  Although the hood 1 and the exhaust blower 2 are engaged by the fastening member in the above description, the hood 1 and the exhaust blower 2 may be engaged by welding. Moreover, in the above, although the case where the exhaust air blower 2 and the L-shaped metal fitting 3 were latched by a fastening member was demonstrated, the exhaust air blower 2 and the L-shaped metal fitting 3 may be latched by welding.

  Although the case where the side plate 2c and the upper plate 2d and the back plate 2a are locked by the fastening member has been described above, the side plate 2c and the upper plate 2d and the back plate 2a are engaged by welding. It may be stopped. Further, although the case where the side plate 2c and the upper plate 2d and the front plate 2b are locked by the fastening member has been described above, the side plate 2c and the upper plate 2d and the front plate 2b are engaged by welding. It may be stopped.

  As described above, in the fixing structure of the ventilation fan according to the first embodiment, both the second attachment portion 3b of the L-shaped metal fitting 3 and the projecting portion 2e of the back plate 2a Since the structure is to be tightened and fixed to the installation wall 4, the load due to the weight of the ventilation fan 100 is dispersed to the L-shaped bracket 3 and the back plate 2 a constituting the exhaust fan 2, so the ventilation fan has a simple structure. It is possible to suppress and prevent the downward sloping of the front side of the 100. Thereby, in the fixing structure of the ventilation fan according to the first embodiment, the size reduction of the L-shaped bracket 3, the weight reduction of the L-shaped bracket 3, and the simplification of the engagement between the L-shaped bracket 3 and the exhaust fan 2 are achieved. It is possible to reduce the weight and cost of the ventilation fan 100. Further, in the fixed structure of the ventilation fan according to the first embodiment, the load of the work of installing the ventilation fan 100 on the installation wall 4 is increased because the simple structure is provided without increasing the number of L-shaped brackets 3. Without this, the ventilation fan 100 can be fixed to the installation wall 4 in the correct posture.

  Therefore, according to the fixed structure of the ventilation fan concerning this Embodiment 1, generation | occurrence | production of the inclination at the time of installation can be suppressed by a simple and cheap structure.
