Hereinafter, embodiments according to the present invention will be described with reference to the drawings.
<First Example>
With reference to FIG. 1 thru | or FIG. 4, the range hood 1 concerning a present Example is demonstrated. The range hood 1 has a thin hood portion 2 having a concave inner surface panel 5 on the inner surface for collecting steam, oily smoke and the like generated by cooking performed below or around. The hood portion 2 is connected to a blower box 3 connected to an exhaust duct (not shown) in the vicinity of the communication port 6 of the inner surface panel 5 located on the upper rear side. The blower box 3 is located on the back side of the curtain plate 9, and has a fan 4 that is a sirocco fan and generates an air flow D1 therein. Therefore, when the fan 4 is operated, the communication port 6 becomes negative pressure, and the air below the inner panel 5 is sucked through the communication port 6 and discharged to the outside through the exhaust duct. The communication port 6 communicates with the fan 4, and is located on the flow path of the air flow D <b> 1 generated by the fan 4 and on the upstream side of the air flow from the fan 4.

  The range hood 1 has a disk-like filter 10 having a hole 11 through which an air flow D1 passes at a position of the communication port 6, and an electric motor 20 having a shaft connected to the center of the disk-like filter 10 and rotating the filter 10. And an electric motor fixture 40 for attaching the electric motor 20 to the inner surface panel 5, and an oil collecting member 30 attached to the inner surface panel 5 and arranged so as to surround the outer peripheral edge of the filter 10. Accordingly, the range hood 1 is on the flow path of the air flow D1 generated by the fan 4 and is present on the upstream side of the flow from the fan 4, and the hole through which the air flow passes from the bottom to the top in the drawing. The filter 10 having 11 is rotatably provided.

  The air below the inner panel 5 contains steam, oily smoke, etc. generated by cooking. When the fan 4 is operated, it exists in the communication port 6, that is, on the flow path of the air flow D <b> 1 generated by the fan 4. Thus, the air is sucked into the hole 11 of the filter 10 located on the upstream side of the fan 4 and passes through the hole 11. The filter 10 is rotatably provided by the electric motor 20, and when the range hood 1 is operated, the fan 4 generates the air flow D1 and the electric motor 20 rotates the filter 10. The range hood 1 collects oil contained in the air in the oil collecting member 30 by rotating the filter 10. Further, the filter 10 is detachably attached to the tip portion of the shaft 21 of the electric motor 20 by the detachable tool 14.

  Such a range hood 1 uses a conventional slot filter, HEPA filter, etc., and has a small pressure loss as compared to improving the oil collecting efficiency by making slits and eyes fine or overlapping to form a multilayer. It can have high oil collection efficiency in the state. Therefore, it is possible to obtain a high oil collection efficiency while maintaining a low ventilation resistance as compared with the conventional filter. In addition, the filter is less likely to clog due to oil adhering to the filter, thereby reducing the cleaning effort of the filter itself and preventing an increase in pressure loss as it is used. Since the oil hardly adheres to the downstream portion, it is possible to provide a range hood that greatly reduces the trouble of cleaning / washing the downstream portion from the filter.

  On the other hand, the oil and fat collecting member 30 that is located upstream of the filter 10 and that collects the oil captured by the filter 10 easily collects oil and fat in a short time. Therefore, it is necessary to attach and detach the oil collecting member 30 frequently in order to discard the accumulated oil and fat.

  The range hood 1 further includes a support portion 50 that supports the back side of the oil collecting member 30 and an engaging portion 60 that engages the front side of the oil collecting member 30. The oil collecting member 30 is attached to the range hood 1 by a part of the back side thereof being supported by the support part 50 and a part of the front side being engaged by the engaging part 60.

  The oil collecting member 30, the support part 50, the engaging part 60, and the collision preventing part 70 will be described with reference to FIGS. The oil collecting member 30 includes a ventilation opening 35 through which air flows generated by the fan 4 pass in the center, an arc-shaped portion having substantially the same width around it, and a linear portion serving as an oil reservoir 31 on the back side. It forms a ring as a whole. The oil collecting member 30 is disposed so as to surround the outer periphery and the lower periphery of the peripheral edge 12 of the filter 10. The filter 10 captures oil contained in the air flowing through the ventilation opening 35 and scatters it toward the peripheral edge 12. The oil collecting member 30 collects oil and the like captured and scattered by the filter 10.

  The oil collecting member 30 surrounds the peripheral edge 12 of the filter 10 from the outside, and receives the scattered oil from the flange 32 and the lower end of the flange 32 to prevent oil and fat from dripping from the range hood. Extending inward (center side) from the flange portion 32, an extending portion 33 covering the lower side of the peripheral edge portion 12 of the filter 10, and rising from the extending portion 33 to the same side as the flange portion 32 (upward), An oil reservoir 31 is formed that has a rising portion 34 that rises from the inner edge of the extending portion 33 toward the filter 10 so as to surround the ventilation opening 35, and retains the oil collected from the filter 10. The flange portion 32 and the rising portion 34 disposed so as to surround the peripheral edge portion 12 of the filter 10 from the outside have a substantially equal distance across the peripheral edge portion 12 in plan view in the arc-shaped portion.

  The oil collecting member 30 has an engaged portion 36 that is a concave portion in order to engage with the engaging portion 60 at a corner portion between the extending portion 33 and the flange portion 32 on the front side. The height of the engaged portion 36 is such that the convex engaging portion is fitted. The oil collecting member 30 has a supported portion 331 supported by the support portion 50 at a corner portion between the extending portion 33 and the flange portion 32 of the back side linear portion. The supported portion 331 is recessed by the thickness of the support portion 50, and the lower surface of the extending portion 33 and the lower surface of the support portion 50 are flush with each other.

  The height from the extending part 33 of the flange part 32 (height of the end part 321) is higher than the peripheral edge part 12 of the filter 10 when the oil collecting member 30 is attached to the range hood 1. It is preferable to be high. Thereby, the oil component scattered on the front surface of the filter 10 can be reliably collected. Therefore, if the height of the flange portion 32 is lowered, the oil collecting member 30 can be prevented from coming into contact with the peripheral edge portion 12 of the filter 10 at the time of attachment / detachment, but cannot be lowered too much.

  Further, the end portion 321 of the flange portion 32 is in a state where the engaging portion 60 is engaged with the front side of the oil collecting member 30, that is, the state where the oil collecting member 30 is attached to the range hood 1. In FIG. 2, it is located above the lower end of the collision prevention part 70 mentioned later. According to this, it is the height which the edge part 321 of the flange part 32 necessarily contacts the collision prevention part 70, and it can prevent that the filter 10 which rotates the oil content collection member 30 and rotates effectively. In addition, the lower end of the collision prevention part 70 means the top part which protruded downward from the inner surface panel 5 in the case of a present Example. Further, the height of the rising portion 34 from the extending portion 33 is a height that does not touch the lower surface of the filter 10 and does not drop the oil component dropped on the extending portion 33.

  The back side linear portion of the flange portion 32 is lower than the other portions by a height H in the width corresponding to the supported portion 331. In other words, the vicinity of both ends of the back side linear portion is higher than the center portion by H. Two end portions in the vicinity of both ends of the back side linear portion abut against the collision preventing portion 70. The height from the extending portion 33 of the end portion 321 of the flange portion 32 at the portion of the peripheral edge portion 12 of the filter 10 near the nearest point NP (shown in FIG. 3A) with the support portion 50 is the back surface. Since the distance from the extending portion 33 of the end portion 321 in contact with the collision preventing portion 70 in the vicinity of both ends of the side linear portion is lower, the distance between the disc-like filter 10 can be increased, and thus the thin portion Also in the hood part, it is possible to effectively prevent the oil collecting member 30 and the rotating filter 10 from contacting each other. Of course, the present invention is not limited to this, and the back side straight portions may all have the same height.

  In the inner surface panel 5, the collision preventing portion 70 is located outside the peripheral edge 12 of the filter 10 and inside the flange 32 (on the filter rotation center side) as viewed from the bottom, and downward from the inner surface panel 5. Raised. More specifically, the lower end of the collision prevention unit 70 is located outside the peripheral edge 12 of the filter 10 and inside the flange 32 (on the filter rotation center side) in the inner surface panel 5 in a bottom view, The inner panel 5 is provided so as to protrude downward. That is, it is only necessary that at least the lower end of the collision prevention unit 70 is located outside the peripheral edge 12 of the filter 10 and inside the flange 32. Since the collision prevention unit 70 is provided so as to be raised, the collision prevention unit 70 includes an inclined portion 71 that forms an inclined surface.

  In a state where the oil collecting member 30 is attached to the range hood 1, the lower end (the top of the raised portion) of the collision prevention unit 70 is located at a position lower than the end 321 that is the upper end of the flange portion 32. In the present embodiment, two collision prevention portions 70 are provided on both sides of the back side of the oil collecting member 30 and in the vicinity of the support portion 50 with the nearest point NP between the peripheral end portion 12 and the support portion 50 interposed therebetween. It is done. By being provided in this manner, when the oil collecting member 30 is attached / detached, the flange portion 32 is prevented from colliding with the peripheral edge portion 12 no matter how it moves in the attaching / detaching direction (back side / front side direction). In addition, the oil collecting member 30 and the rotating filter 10 can be prevented from contacting each other.

  The support part 50 is provided in the vicinity of the back side from the communication port 6 and supports the supported part 331 formed in the extending part 33 of the oil collecting member 30. The engaging portion 60 is provided in the vicinity of the front side from the communication port 6 so as to be able to protrude and retract in the front-rear direction (front / rear direction), and urges the engaged portion 36 of the oil collecting member 30 by an elastic member such as a spring. Provided. A person who wants to remove the oil collecting member 30 operates the engaging portion 60 against the biasing force to disengage the engaging portion 60 and the engaged portion 36. The engaging portion 60 is not limited to this, and is engaged with the engaged portion 36 when the oil collecting member 30 is mounted, and can be easily disengaged when attempting to remove it. Good.

  The above has described the state in which the engaging portion 60 engages the engaged portion 36 of the oil collecting member 30, that is, the state in which the oil collecting member 30 is attached to the range hood 1. The case where the oil collecting member 30 is removed from the range hood 1 will be described with reference to FIGS. This figure shows a state in which the engaging portion 60 is disengaged from the engaged portion 36 of the oil collecting member 30 and the oil collecting member 30 is supported only by the support portion 50.

  A user (a person who attaches or detaches the oil collecting member 30) tries to remove the oil collecting member 30 from the range hood 1, operates the engaging portion 60, and engages the engaging portion 60 and the oil collecting member 30. The engagement with the engaged portion 36 is released. When the engaging part 60 is disengaged from the front side of the oil collecting member 30, the oil collecting member 30 is only supported by the support part 50 at one side on the back side, so that only the front side is caused by gravity. Try to fall down. Normally, the user supports the front side of the falling oil collecting member 30 with his hand and tries to take out the oil collecting member 30 in the forward direction (front direction) and slightly obliquely downward.

  At this time, since the back side of the flange portion 32 has a certain height from the supported portion 331, the end portion 321 is easily caught on the peripheral end portion 12 of the filter 10 when there is nothing. However, the collision preventing portion 70 is provided outside the peripheral edge portion 12 of the filter 10 and inside the flange portion 32 so as to protrude downward from the inner surface panel 5 so that the end portion 321 of the flange portion 32 contacts. It has been. If it does so, the collision prevention part 70 will prevent the flange part 32 from colliding with the peripheral edge part 12 in the process in which the oil content collection member 30 is removed from the range hood 1. FIG. According to this, when the oil collecting member 30 is attached and detached, the flange portion 32 of the oil collecting member 30 abuts against the collision preventing portion 70 and the flange portion 32 is prevented from colliding with the peripheral edge portion 12. It is possible to prevent the oil collecting member 30 and the rotating filter 10 from contacting each other.

  In addition, when the user performs an operation of lifting the back side when the oil collecting member 30 is completely removed from the range hood 1, as shown in FIG. Even when the support portion 331 is separated from the support portion 50, the end portion 321 of the flange portion 32 abuts against the collision prevention portion 70. According to this, even when the oil collecting member 30 leaves the contact with the range hood 1 and is subsequently removed, the flange 32 comes into contact with the collision preventing unit 70, so that the oil collecting member 30 and It is possible to prevent the rotating filter 10 from contacting. Then, the user can pull the oil collecting member 30 tilted in this way to the front side, so that the oil collecting member 30 can be completely removed from the range hood 1 without contacting the filter 10.

  Moreover, the collision prevention part 70 protrudes downward from the inner surface panel 5, and the end part 321 of the flange part 32 is provided so that it may contact | abut to the inclination part 71 which makes the raised slope of the collision prevention part 70, when it attaches / detaches. . The inclined portion 71 forms a surface that is inclined from the top portion that protrudes downward from the inner surface panel 5 toward the flange portion 32 in the vicinity and toward the base of the protrusion. Further, the collision prevention unit 70 may extend downward from the inner panel 5 and have an inclined portion. According to this, the oil collecting member 30 and the rotating filter 10 are smoothly prevented from coming into contact with each other by sliding in contact with the inclined portion of the slope formed by the flange portion being raised or extended. can do. Further, since the flange portion slides in contact with the inclined portion of the collision preventing portion 70, the oil collecting member 30 can be guided in the removing direction, and the operability during removal can be improved.

<Second Example>
With reference to FIG. 10 and FIG. 11, the collision prevention part concerning a present Example is demonstrated. In order to avoid duplication, differences from the above embodiment will be mainly described.

On the other hand, in the above embodiment, there are two collision prevention portions 70 and both are provided on the back side. However, in this embodiment, there are three or more collision prevention portions 70A on either side. Not biased to. According to this, it is possible to prevent the oil collecting member 30A and the rotating filter 10A from coming into contact from any direction.

  As shown in FIG. 10 (A), at least two collision preventing portions 70A have a curvature of an arc CA1 passing through three points, that is, one point PT of the peripheral edge portion 12 and two points of the at least two collision preventing portions 70. It is preferable to arrange so as to be smaller than the curvature of the flange portion 32A. According to this, even if oil collecting member 30A moves in any direction in parallel, it is possible to reliably prevent oil collecting member 30A and rotating filter 10A from contacting each other.

  In FIG. 10B, the curvature of the arc CA2 passing through the three points of the one point PT of the peripheral edge portion 12A ′ and the two points of the two collision prevention portions 70A ′ is substantially the same as the curvature of the flange portion 32A ′. The case is shown. In such a case, the flange portion 32A 'is in contact with the collision preventing portion 70A' and substantially in contact with the peripheral edge portion 12A '. Accordingly, when the curvature of the arc passing through one point PT at the peripheral edge portion and two points at the two collision prevention portions is larger than the curvature of the flange portion, the flange portion is in contact with the collision prevention portion. It turns out that it contacts a peripheral edge part.

  FIG. 10C shows three collision preventing portions 70B that are in a 120 ° relationship with each other about the center of rotation. FIG. 10D shows four collision prevention units 70 </ b> C that are in a 90 ° relationship with each other about the center of rotation. FIG. 10E shows five collision prevention portions 70D that are in a 72 ° relationship with each other about the rotation center. FIG. 10F shows six collision prevention units 70E that are in a 60 ° relationship with each other about the center of rotation. In any of the collision prevention portions, at least two of the collision prevention portions are such that the curvature of the arc passing through one point of the peripheral edge portion and two points of the at least two collision prevention portions is smaller than the curvature of the flange portion. Is arranged.

  FIG. 11 shows the periphery of the oil content collecting member 30E and the filter 10E having six collision prevention portions 70E shown in FIG. The collision prevention unit 70E extends downward from the inner surface panel 5E and has a lower end positioned below the peripheral edge 12E of the filter 10E. Moreover, the collision prevention part 70E has the inclination part 71E on the opposite side (outside) from a rotation center. According to this, even if the oil collecting member approaches from any direction, it is possible to reliably prevent the oil collecting member 30E and the rotating filter 10E from contacting each other.
