In addition, the front end corner of the interior panel 5 is screwed and fixed to the hood case 4 after the inner edge of the interior panel 5 is locked.

  The back wall portion of the hood case 4 is equipped with an illumination lamp 13 and various electric devices, and these are covered by the interior panel 5. The interior panel 5 is provided with a lamp cover 14 made of a glass plate or a translucent resin plate so as to be openable and closable. The front surface of the illumination lamp 13 is covered with the lamp cover 14 when the panel is attached. The front surface of the hood case 4 is equipped with an operation unit 15 for performing various operations and settings, and a gap formed between the hood case 4 and the interior panel 5 is a wiring space.

  An oil tray 16 provided with an annular oil reservoir 16a, which is an oil reservoir that receives and collects oil flowing down from the suction port 10, is detachably mounted on the ceiling of the interior panel 5. The details of the oil tray 16 mounting structure will be described later.

  The rectifying plate 6 is configured in a substantially rectangular flat plate shape that is slightly smaller than the downward opening in the hood case 4. As shown in FIG. 2, the rectifying plate 6 locks the connecting metal fittings 19 with holes provided on the left and right sides of the back end thereof to the left and right hooks 20 provided on the back side of the interior panel 5. Locking pins 22 provided on the left and right sides of the interior panel 5 are attached to the connecting fittings 21 with holes projecting to the left and right of the rectifying plate 6 by lifting and swinging the rectifying plate 6 around the stopping point. The rectifying plate 6 is fixed to a predetermined loading position with respect to the interior panel 5 by being engaged with each other.

  In a state where the rectifying plate 6 is set at the loading position, an annular flow path 23 is formed between the outer peripheral end of the rectifying plate 6 and the peripheral wall portion of the interior panel 5. Further, as shown in FIG. 3, there is a hood internal passage 24 between the lower surface of the interior panel 5 and the upper surface of the rectifying plate 6, and the flow passage 23 and the suction port 10 are connected via the internal hood passage 24.

  In addition, a recessed portion 6a corresponding to the lamp cover 14 is formed at the central portion of the back end side of the rectifying plate 6 so that light from the illumination lamp 13 is widely irradiated downward and forward without being blocked by the rectifying plate 6. It is like that.

  4 is a cross-sectional view taken along the line AA in FIG. 3, and FIG. 5 is a perspective view of the exhaust fan 2 as viewed from below.

  Referring to FIGS. 3 to 5, an exhaust fan 2 made of a sirocco fan provided in an air flow path has a large number of fans across an upper support plate 25 and a lower support plate 26 formed in a flat ring shape. The blades 27 are supported at a constant pitch in the circumferential direction, and the upper and lower intermediate portions of the fan blades 27 are supported through the intermediate support plate 28.

  A fan boss 29 is connected and fixed at the center of the lower surface of the intermediate support plate 28, and a connecting boss portion 29 a that can be inserted into and removed from the downward rotating shaft 9 of the motor 8 from below is provided at the center of the fan boss 29. It protrudes upwards through. The fan boss 29 can be connected to and released from the rotating shaft 9 inserted into the connecting boss portion 29a by a known one-touch attaching / detaching means.

  That is, a torque transmission drive pin 30 is penetratingly fixed laterally at an upper and lower intermediate portion of the rotating shaft 9, and a connecting groove 31 is formed near the lower portion of the rotating shaft 9. When the exhaust fan 2 is lifted and the connecting boss portion 29a of the fan boss 29 is inserted into the rotating shaft 9 from below, it rotates into the V-shaped engaging groove 32 formed in a cross shape at the upper end of the connecting boss portion 29a. The rotating shaft 9 follows and rotates so that the drive pin 31 of the shaft 9 is engaged. When the connecting portion 29a is inserted into the rotating shaft 9 to a predetermined depth and the driving pin 30 is correctly engaged with the engaging groove 32, a lock claw (not shown) built in the fan boss 29 automatically rotates. The rotating shaft 9 and the exhaust fan 2 are connected to each other so as to be integrally rotatable with the connecting groove 31 of the shaft 9.

  When the release knob 33 provided on the outer peripheral portion of the fan boss 29 is pushed into the boss center side, the built-in lock claw is forcibly retracted in the engagement release direction against the engagement biasing force. In this state, the exhaust fan 2 can be pulled down and removed from the rotating shaft 9, and the exhaust fan 2 can be attached and detached during cleaning with a one-touch operation.

  In the present embodiment, the exhaust fan 2 configured as described above is provided with a function of collecting oil in the exhaust gas, and the oil collecting means will be described below.

That is, an oil collecting member 35 that attaches oil droplets in the exhaust or condenses and collects oil vapor in the exhaust is attached and fixed inside the lower half of the exhaust fan 2. The oil collecting member 35 is made of, for example, a thin metal plate such as iron or stainless steel having excellent corrosion resistance, and has a cylindrical peripheral portion 35a as a cylindrical portion and a circular upper bottom portion 35b, and is opened downward. The bottomed cylindrical shape is formed. The oil collecting member 35 is
A large number of vent holes 36a, 36b having a small cross-sectional area are densely arranged in each of a peripheral portion 35a and an upper bottom portion 35b along the inner periphery of the group of fan blades 27. The shape of the vent is not particularly limited, and may be, for example, a circle, an ellipse, a rectangle, a cross, or a slit. The oil collecting member 35 may be configured by a punching metal in which the vent holes are uniformly punched and formed, or a net body knitted with a wire.

  In addition, the upper bottom part 35b is arranged a little away from the intermediate support plate 28 so that the vent hole 36b of the upper bottom part 35b is not blocked by the radial arm 28a provided in the intermediate support plate 28. .

  The range hood 1 according to the present embodiment is configured as described above, and the exhaust gas is discharged from the flow path 23 formed on the outer periphery of the rectifying plate 6 by the negative pressure generated as the exhaust fan 2 rotates. Exhaust air sucked into the suction port 10 and sent out by the exhaust fan 2 is guided by the fan casing 7 and guided to the exhaust duct 11.

  When the exhaust passes through the air holes 36a and 36b of the oil collecting member 35, fine oil droplets contained in the exhaust adhere to the surface of the oil collecting member 35 and the air holes 36a and 36b. The oil vapor contained therein condenses due to fluctuations in atmospheric pressure caused by turbulence generated when the exhaust gas passes through the groups of the air holes 36a, 36b, and adheres to the surface of the oil collecting member 35 and the air holes 36a, 36b. To do. And the oil component adhering to the surface of the oil collecting member 35 and the vent holes 36a and 36b in this way is dispersed as a plurality of fine oil droplets. When even a part of the oil comes into contact, the oil tray is deformed into a large granule with an increased volume per droplet due to the surface tension of the oil, and flows down by its own weight while the fan is stopped, and an oil tray disposed below the exhaust fan 2 The oil is collected in an annular oil reservoir 16 a recessed below 16.

  The oil adhering to the inner surface of the fan casing 7 flows down by its own weight, is guided to the suction port 10 side through the casing bottom surface 7a, and is collected in the oil reservoir 16a of the oil tray 16. Here, the bottom surface 7 a of the fan casing 7 is inclined downward toward the suction port 10, so that the oil easily flows down to the oil tray 16 without staying on the bottom surface 7 a.

  The surface of each member that is in contact with the exhaust, such as the current plate 6, the interior panel 5, and the fan casing 7, is provided with an oil guard coating to impart oil repellency, and the attached oil flows smoothly. The attached oil can be easily wiped off. Further, the oil tray 16 is provided with a hydrophilic coating, so that the oil adhering to the oil tray 16 is easily lifted and removed by immersing the oil tray 16 in water.

  In this embodiment, the mounting structure of the oil tray 16 is as follows so that the oil liquid stored and recovered in the oil tray 16 can be discarded without accidentally spilling.

  6 is a perspective view of the oil tray 16 as viewed from above, FIG. 7 is a perspective view of the oil tray 16 as viewed from below, FIG. 8 is a plan view of the oil tray 16, and FIG. FIG. 10 is a bottom view of the oil tray 16, FIG. 10 is a side view of the oil tray 16, and FIG. 11 is a cross-sectional view taken along line BB in FIG.

  As shown in FIGS. 8 and 9, the oil tray 16 has a circular ring shape in plan view, and the oil reservoir 16 a recessed downward is formed in an annular shape along the circumferential direction.

  In this embodiment, in order to rotate and remove the oil tray 16, the outer wall of the oil tray 16 having the bottom wall portion and the peripheral wall portion is movable-side engaged at a constant pitch along the circumferential direction. Engaging recesses 44, which are parts, are formed at a plurality of locations (three locations in this example). Further, on the lower surface of the bottom wall portion of the oil tray 16, a handle 50 for holding with both hands when the oil tray is attached and detached is attached to a position opposed in the diameter direction.

  The handle 50 has a shape protruding downward. In this embodiment, the handle 50 has an arch shape that protrudes downward. Specifically, both ends of the handle 50 are attached to the lower surface of the bottom wall portion of the oil tray 16, are formed obliquely downward from the both ends, bent in the horizontal direction, and protruded downward. The portion extends in parallel to the lower surface of the oil tray 16. Therefore, the handle 50 is located below the bottom wall portion of the oil tray 16.

  The handle 50 of this embodiment is attached to the oil tray 16 as follows. That is, three long and short mounting bases 51 are welded and fixed to the lower surface of the oil tray 16, and both ends of both handles 50 are connected and fixed to the flat seat surface of the mounting base 51.

  The handle 50 itself has a width and a height that allow the metal band plate material to be grasped with one hand, and is bent and formed into an arch shape whose central portion protrudes downward as described above. Both ends of the handle 50 are caulked or screwed to the mounting base 51 via caulking pins. Of the three mounting bases 51, a triangular arrow mark 46 is formed at the center in the longitudinal direction of the mounting base 51 that is long in the circumferential direction.

  Thus, since the handle 50 is connected to the mounting base 51 with caulking pins or screws, there is no need to form a connection hole for attaching the handle to the oil tray 16 itself. Therefore, the oil accumulated in the oil tray 16 does not leak from the connection hole. Further, the bottom surface of the oil reservoir in the oil tray 16 can be made smooth without a connecting hole, and the oil liquid can be easily wiped off and washed.

  In addition, the handle should just have the shape which protrudes below, and is not restricted to the said shape, For example, the shape which protrudes below in circular arc shape or a triangular shape may be sufficient.

  As another embodiment of the present invention, as shown in the perspective views of FIGS. 12 and 13, a flat seat surface 16b is integrally formed on the bottom surface of the oil tray 16, and a handle 50 is formed on the seat surface 16b. You may make it attach. That is, the mounting base 51 may be omitted, and the handle 50 may be directly attached to the bottom surface of the oil tray 16. In this case, it is not necessary to form a connection hole for attaching the handle to the oil tray 16 itself by attaching the handle 50 to the flat seat surface 16b of the oil tray 16 by spot welding, for example.

  As shown in FIG. 3, a decorative plate as a support member having a circular opening for mounting the oil tray 16 on the hood-side hood case 4 to which the oil tray 16 is detachably engaged and connected. 40 is connected and fixed. The oil tray 16 is inserted into the opening of the decorative plate 40 from below, and the engagement of the oil tray 16 is performed at a plurality of engagement connecting portions 41 (three in this example) arranged at an equal pitch in the circumferential direction. The recess 44 is configured to be detachably engaged with an engagement fitting 42 as a fixed side engagement portion fixed to the decorative plate 40.

  The engagement fitting 42 screwed to the decorative plate 40 is made of a leaf spring material, and as shown in FIG. 14, the free end side of the curved arm portion 42a bent in an inverted U shape and elastically deformable in the inner and outer directions. Further, the engagement protrusion 43 is formed by stamping inward (in a direction approaching the oil tray 16).

  FIG. 15 is a vertical cross-sectional view of the engagement connection portion 41 between the oil tray 16 and the engagement fitting 42 in the engagement start state, and FIG. 16 is a vertical cross-sectional view of the engagement connection portion 41 in the middle of rotation. FIG. 17 is a vertical cross-sectional view of the engagement connection portion 41 in a state of overpassing, and FIG. 18 is a vertical cross-sectional view of the engagement connection portion 41 in the engagement end state.

  As shown in FIGS. 15 and 16, the lower end portion of the curved arm portion 42 a of the engagement metal fitting 42 is abutted and supported by the peripheral wall 40 a erected on the inner edge of the opening of the decorative plate 40, and the engagement protrusion 43 is formed. It can be elastically retracted outward (in the direction away from the oil tray 16), so that inward displacement is prevented from contacting at a predetermined position.

  The engagement recess 44 of the oil tray 16 has a saddle shape in which a lateral groove 44b is provided along the circumferential direction at the lower end of a longitudinal groove 44a opened upward as shown in FIGS. Is formed. Thus, after the oil tray 16 is lifted and the engagement protrusion 43 of the engagement fitting 42 is introduced into the longitudinal groove 44a, the oil tray 16 is horizontally rotated around the longitudinal axis passing through the annular center, that is, The oil tray 16 can be engaged with and supported by the engagement fitting 42 so as not to drop by being rotated along the annular oil reservoir 16a and guiding the engagement protrusion 43 to the lateral groove 44b.

  Further, a small ridge 45 is provided on the bottom surface of the groove that is slightly in front of the rear end position of the lateral groove 44b, which is the engagement end position e. The small ridge 45 is set to a height that slightly interferes with the tip movement locus of the engaging protrusion 43 that relatively moves along the horizontal groove 44b. As shown in FIG. Since the bending arm portion 42a is bent outward and deformed, the engaging protrusion 43 can pass over the small ridge 45 and pass through.

  Therefore, at the engagement end position e where the engagement protrusion 43 is relatively moved over the small protrusion 45 to the far end of the lateral groove 44 b, the oil tray 16 is connected by the interference between the small protrusion 45 and the engagement protrusion 43. Overcoming resistance is given to the rotation in the release direction, and the oil tray 16 is stably held without being reversely rotated inadvertently.

  Here, the depth d1 of the vertical groove 44a and the horizontal groove 44b shown in FIG. 11 is such that a slight gap is formed between the groove bottom and the tip of the engaging protrusion 43 as shown in FIGS. That is, the depth d2 is set to be larger than the engagement allowance with the engagement protrusion 43, and the depth d2 at the back side portion of the small bulge 45 of the lateral groove 44b is set to be shallower than the depth d1. Therefore, the oil tray 16 can be rotated with less sliding resistance in the insertion process of guiding the engaging protrusion 43 to the vertical groove 44a and the process of moving the engaging protrusion 43 along the horizontal groove 44b. Further, at the engagement end position e where the small protrusion 45 is passed over and the engagement protrusion 43 is moved to the far end of the lateral groove 44b, the tip of the engagement protrusion 43 is elastically pressed against the groove bottom as shown in FIG. Thus, the oil tray 16 can be stably held in the horizontal direction without rattling.

  Incidentally, the depth d1 of the vertical groove 44a and the horizontal groove 44b is about 3 mm, and the depth d2 in the back side part from the small ridge 45 of the horizontal groove 44b is about 2.5 mm. The vertical width of the vertical groove 44a is about 3.5 mm, the vertical width of the horizontal groove 44b is about 2 mm, and the length along the circumferential direction is about 30 mm.

  As described above, the oil tray 16 is slidably engaged with the engaging recess 44 formed on the outer periphery thereof from the circumferential direction and is connected and supported at a predetermined position. The oil tray 16 can be easily removed by gripping 50 with both hands and rotating the oil tray 16 in the circumferential direction. Therefore, when a care sign is issued, the rectifying plate 6 is swung downward, the grips 50 are held by both hands, and the oil tray 16 is rotated in the opposite direction to be removed and collected. Oil can be discarded.

  When the oil tray 16 is removed, the engagement projection 43 passes over the small ridge 45 and passes through the small projection 45 so that the oil tray 16 is rotated in the reverse direction with a little force. When the engagement protrusion 43 moves to the vertical groove 44a, the engagement protrusion 43 may collide with the groove wall of the vertical groove 44a excessively, and the oil in the oil reservoir 16a may flow due to the impact. . In this case, since the oil reservoir 16a of the oil tray 16 is annular, the accumulated oil liquid only flows in the circumferential direction in the oil reservoir 16a and does not overflow from the oil reservoir 16.

  When the oil tray 16 is attached, the engagement protrusion 43 and the engagement recess 44 are not clearly visible from below. Therefore, in order to facilitate the engagement operation of the engagement connecting portion 41, the above-described alignment triangle is used. The alignment is performed by the arrow mark 46 and the like as follows.

  That is, as shown in FIGS. 7 and 9, the triangle on the lower surface of the oil tray 16 corresponds to the engagement start position s which is the formation position of the vertical groove 44 a in the engagement recess 44 shown in FIG. 10. An arrow mark 46 is provided, and a triangular arrow mark 47 for starting engagement corresponding to the installation position of the engagement fitting 42 is provided on the lower surface of the decorative plate 40 as shown in FIG. By aligning the mark 46 with the mark 47 in the circumferential direction and lifting the oil tray 16, the engagement protrusion 43 can be guided to the vertical groove 44a in the engagement recess 44 as shown in FIG. it can.

  Further, as shown in FIG. 9, when the engagement protrusion 43 gets over the small ridge 45 on the lower surface of the decorative board 40 and reaches the back end of the lateral groove 44b, that is, the engagement end position e shown in FIG. An engagement end mark 48 facing the mark 46 is provided, and when the oil tray 16 is rotated in the mounting direction, the engagement projection 43 is rotated to the correct mounting position over the small projection 45. This can be confirmed visually. As a result, it is possible to avoid the misunderstanding that the attachment is completed due to the engagement protrusion 43 coming into contact with the small protrusion 45.

  Further, as described above, the pair of arch-shaped handles 50 project downward from the lower surface of the oil tray 16 so as to be located at locations facing each other in the diametrical direction. By firmly grasping with both hands, the oil tray 16 can be accurately rotated without sliding the hands. Further, by firmly holding the oil tray 16 via the handle 50, it is possible to handle the oil liquid from the oil tray 16 in which the oil liquid is accumulated without spilling, thereby improving the handleability.
