However, the range hood 5 has the following problems.
That is, the range hood 5 has an open space on the left and right side surfaces in the frontage direction, a back surface formed in the depth direction between the both side surfaces and linearly inclined forward, and the back surface portion Smoke generated by cooking in the cooking facility 4 or the like because it is only surrounded by a ceiling surface portion that is continuous forward from the top and a front surface portion that extends linearly downward from the front end of the ceiling surface portion. When a part S1 such as the above leaks to the outside, it cannot be pulled back to the open space, which is not sufficient in terms of smoke collection ability.

  In addition, since the inner surface portion has a complicated shape in which the inner surface portion is linearly angular, there is a problem in terms of cleaning workability because oil easily adheres to the corner portion.

  Further, since the exhaust port 6 opened in the back surface portion of the range hood 5 is formed widely between both side surface portions in order to reliably collect the sucked smoke, the filter 7 attached to the exhaust port 6 is provided. However, there is a problem in terms of enlargement of the outer shape of the range hood 5 or cleaning workability.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a range hood that has high smoke collection capability, is easy to clean, and can be miniaturized.

  In order to solve the above problem, the invention according to claim 1 is a range hood provided above a cooking facility, and is disposed between a side plate and a side plate respectively provided on the left and right sides. And a guide portion that forms a collection space in which a lower portion facing the cooking equipment opens to generate a swirling flow, and the guide plate has an arcuate shape with a substantially arc-shaped longitudinal section. A substantially planar guide surface that is connected to the rear end portion of the arc-shaped surface at the upper end portion, and is inclined to rise forward at an angle smaller than the rear end portion of the arc-shaped surface; The guide surface and the arcuate surface are provided with a recess in which the left and right ends of the arcuate surface are recessed toward the rear.

  In the invention according to claim 1 configured as described above, smoke or the like generated by use of cooking equipment is guided along the guide plate to generate a swirling flow, for example, from a substantially central position where the swirling flow converges, It is reliably sucked from the openings provided in the both side plates and discharged to the outside. Due to the swirling flow, a negative pressure is generated around the lower opening of the range hood, and a high collection efficiency can be obtained.

  Further, since smoke or the like is converged as a swirling flow, the opening portion can be made small, and thus the outer shape of the range hood can be reduced, and high cleaning workability can be obtained. Furthermore, since the collection space having the opening facing the cooking equipment of the range hood is surrounded by a guide portion composed of a guide plate and a side plate, the inner surface is simple with no irregularities, such as attached oil droplets. High cleaning workability can be obtained.

  Further, since smoke or the like can be swung along an arcuate surface having a substantially arcuate longitudinal section, a swirling flow can be generated more reliably and high collection efficiency can be obtained. Further, since the arcuate surface is a smooth surface, the attached oil droplets can be more easily cleaned.

  In addition, since it has a guide surface that is tilted forward and rises and is connected to the rear end of the arcuate surface at the upper end, the smoke or the like is moved forward before the rising smoke is introduced into the arcuate surface. It can be rectified so as to proceed upward. Therefore, a swirl flow can be generated more reliably on the arcuate surface.

  By forming recesses by recessing the left and right ends of the guide plate toward the rear, guide surfaces to the filter can be formed along with the depths at the left and right ends of the rear portion in the collection space. Therefore, it is possible to prevent the smoke and the like from flowing out to the left and right outside even in the rear portion of the collection space where the smoke and the like before being rectified by the guide plate collide. Therefore, the collection efficiency can be further improved.

  Furthermore, in the invention according to claim 2, the depth in the depth direction of the concave portion is deepest in the vicinity of the boundary between the guide surface and the arcuate surface, and is continuous in the vertical direction from the vicinity of the boundary. The structure gradually changes so as to become shallower.

  According to a third aspect of the present invention, a suction device is disposed on the back side of the guide surface, and the concave portion is positioned on both sides of the suction device.

  According to the present invention, smoke and the like can be prevented from flowing out even when the vertical size is reduced, and both design and space saving can be achieved.

  Hereinafter, each embodiment embodying the present invention will be described.

  As shown in FIG. 1 and FIG. 2, the system kitchen 10 has a base cabinet 11 installed on the floor surface, and the wall cabinet is placed on the wall surface along the floor surface so as to face the counter 12 of the base cabinet 11. It is provided. The counter 12 of the base cabinet 11 is provided with a stove 13 as cooking equipment, and cooking such as cooking is possible. On the other hand, a range hood 14 is provided at a position above the stove 13 so that smoke and hot air (such as smoke) S generated by heating cooking on the stove 13 are sucked and discharged outdoors. .

  The range hood 14 includes a range hood main body 14a composed of left and right side outer plates 14b, a front plate 14c, a back plate 14d, and a ceiling plate 14e so as to open a lower portion facing the stove 13. The sirocco fan 15 as a suction device provided on the inner rear side of the range hood main body 14a and the front area of the sirocco fan 15 are disposed so as to surround the lower side facing the stove 13 in an open state. It comprises a guide part 16.

  The guide portion 16 includes a side plate 16a provided so as to be opposed to both the left and right sides, and a guide plate 16b provided with a part thereof curved forward at a position between the side plates 16a. Consists of. The both side plates 16a are each provided with a substantially circular opening 16c for suction and exhaust at positions to be described later, and a substantially circular filter 17 corresponding to the shape of the opening 16c is formed by screwing (not shown), for example. It is detachably mounted.

  Further, the guide plate 16b is continuous from the front end of the sirocco fan 15 provided on the inner rear side of the range hood main body 14a so as to incline forward and the upper end of the guide surface 16d. Then, it is composed of an arcuate surface 16e that is curved so that the longitudinal section thereof is substantially arcuately directed forward, and the tip edge thereof faces downward. Smoke and the like S generated by cooking on the stove 13 is sucked from the opening 16c by the sirocco fan 15 through a flue 18 described later. The flow of smoke or the like at this time is regulated and guided by the guide plate 16b.

  That is, as shown in FIG. 2 and FIG. 3, the smoke S or the like first reaches the guiding surface 16d, is rectified upward along the guiding surface 16d, and is guided to the arcuate surface 16e. It flows while being regulated along the arcuate surface 16e, and a swirling flow is generated in the vertical direction. Alternatively, smoke or the like directly reaches the arcuate surface 16e and similarly generates a swirling flow. The swirl flow is sucked into the flue 18 through the filter 17 at both openings 16c provided in the side plate 16a while gradually converging toward the center of rotation of the cross section.

  The side plate 16a and the guide plate 16b constituting the guide portion 16 are disposed to face each other with a space between the range hood main body 14a, and a section serving as a flue 18 is formed between the side plate 16a and the guide plate 16b. That is, a side flue 18a as a flue 18 is formed between the both side outer plates 14b and the both side plates 16a. Further, a main flue 18b as a flue 18 is formed between the both guide surfaces 16b and the ceiling plate 14e. The sirocco fan 15 is disposed in the main flue 18b, and is connected to the side flue 18a so that smoke or the like S can be sucked from the opening 16c.

Further, the lower end of the section in which each flue 18 is formed is closed, and an oil droplet guide passage 19 is formed. That is, an oil droplet guideway 19a is provided at the lower end of the both-side flue 18a, and an oil droplet guideway 19b is provided at the lower end of the main flue. The oil droplet guide path 19a is inclined so as to gradually descend from the front toward the rear of both ends of the range hood main body 14a where the oil receiver 20 described later is disposed. Similarly, the oil droplet guide path 19b is substantially inverted V-shaped at both ends in the frontage direction so that the center in the frontage direction protrudes upward toward the rear of both ends of the range hood body 14a where the oil receiver 20 is disposed. It is inclined to the shape.

  As shown in FIG. 4, oil receivers 20 are detachably provided at the innermost end of the two-side flue 18a and at both ends in the front-end direction of the main flue 18b. . The oil receiver 20 is, for example, formed in a tray shape having a height × width × depth of about 10 mm × 150 mm × 50 mm, and at the above position, it is one step lower than the oil droplet guide paths 19a, 19b. And the upper part is open | released so that an oil droplet can flow in, and it arrange | positions in the state which can be pulled out in the front-back direction. Therefore, the oil droplets dripped from the inner walls of each flue 18 are guided to the oil receiver 20 in the inclined direction via the oil droplet guide passage 19 and accumulated. Since the oil receiver 20 can be easily detached as described above, it is possible to easily discard the oil droplets collected regularly.

  The sirocco fan 15 is disposed in the innermost part of the main flue 18b so that the rotation axis direction thereof is the front-rear direction. The sirocco fan 15 includes a fan main body 15a, a fan casing 15b that surrounds the fan main body 15a and supports the fan main body 15a so as to be rotatable, and a motor (not shown). The fan casing 15b is provided with a suction opening 15c in the vicinity of the rotation center of the fan body 15a, and can suck smoke from the opening 15c to the center of the fan body 15a. Further, the fan casing 15b is provided with an exhaust cylinder 15d so as to extend in the direction of the rotation tangent to the fan main body 15a at the upper end, and oil drops dropped by the rotational centrifugal force of the fan main body 15a at the lower end of the fan casing 15b. A discharge port 15e for discharging to the outside is provided so as to be positioned above the oil droplet guide path 19b.

  The exhaust cylinder 15d is connected to the duct 21 so that smoke or the like sucked by the sirocco fan 15 can be discharged outdoors. As described above, the sirocco fan 15 is disposed in the innermost part of the main flue 18b so that the rotational axis direction thereof is the front-rear direction, and therefore can be disposed extremely compactly in the front-rear direction. Therefore, the range hood 14 can be reduced in size.

  Further, since the sirocco fan 15 has a structure in which it is sucked from the center and discharged to the outer periphery by centrifugal force, the oil droplets contained in the sucked smoke are forcibly scattered to the outer periphery by centrifugal force. Will be. These oil droplets hit the inner surface of the fan casing 15b, are dripped, and are discharged very efficiently from the discharge port 15e provided at the lower end of the fan casing 15b, and are easily discharged by the oil receiver 20 through the oil droplet guide path 19b. The amount of oil droplets attached to the fan body 15a itself can be reduced, and the frequency of cleaning can be reduced.

  Further, the exhaust cylinder 15d is provided so as to extend in the upward direction of the fan main body 15a rotation tangent at the upper end of the fan casing 15b, so that smoke or the like sucked with low resistance can be discharged efficiently. In addition, the oil droplets scattered by the centrifugal force described above can easily fall due to their own weight, and can suppress the amount of mixture into the exhaust smoke. Although the above description has focused on each structure of the range hood 14, functions when the range hood 14 is used will be described below.

  Smoke S and the like generated when cooking with the stove 13 flows to the range hood 14 disposed above. In the range hood 14, the smoke S that has reached the guide surface 16d flows upward along the guide surface 16d, is guided to the arc-shaped surface 16e, and is then regulated along the arc-shaped surface 16e. It flows while producing a swirling flow in the vertical direction. Alternatively, the smoke S directly reaching the arcuate surface 16e similarly generates a swirling flow. The swirl flow is sucked into the two-side flue 18a through the filter 17 at both openings 16c provided in the side plate 16a while gradually converging toward the center of rotation of the cross section.

  At this time, in the filter 17, a part of the oil contained in the smoke or the like is filtered and collected by an oil receiver (not shown) or an oil absorbing member provided integrally in the filter 17. The smoke or the like sucked into the both-side flue 18a is sucked into the suction opening 15c provided in the fan casing 15b of the sirocco fan 15 disposed in the main flue 18b via the both-side flue 18a. Then, the sucked smoke and the like are sucked and passed from the rotation center of the fan main body 15a to the outer periphery of the fan body 15a and exhausted to the outside through the exhaust cylinder 15e.

  Moreover, although the smoke etc. which pass through the inside of each flue 18 have some oil filtered by the filter 17, they may still contain oil. A part of such oil adheres to the inner wall surface constituting each flue 18. The adhering oil droplets flow down along the inner wall due to their own weight and reach the oil droplet collecting passage 19 (19a, 19b) at the lower end of the flue 18 (18a, 18b). Then, the oil is guided along the inclination of the oil droplet collection path 19 and flows down to the oil receiver 20 to be collected.

  Furthermore, a part of the oil contained in the smoke and the like passing through each flue 18 is scattered on the outer periphery by the rotational centrifugal force of the fan body 15 a when sucked by the sirocco fan 15. These oils adhere to the inner wall of the fan casing 15b, then flow down along the inner wall, and are discharged from the discharge port 15e. The oil droplets discharged from the discharge port 15e are guided along the inclination of the oil droplet guide path 19b disposed below, and flow down to the oil receiver 20 and are collected. The oil droplets collected in the oil receiver 20 in this way can be discarded by removing the oil receiver 20. Moreover, the desorbed oil receiver 20 can be washed.

  In addition, this invention is not limited to the structure of a present Example, About the structure listed below, it can change suitably. The position of the oil receiver is not limited to the deepest position at both ends of the range hood main body, and may be arranged at other positions as long as the oil droplets guided by the oil droplet guiding path can be collected. For example, the oil droplet guideway provided in the lower part of the main flue is formed in a V shape inclined from both ends toward the substantially central part in the frontage direction, and arranged so as to receive the oil droplets below the substantially central part. Also good. In this case, if the oil droplets guided by the oil droplet guideway provided in the lower part of the side flue are also drawn into the oil droplet guideway provided in the lower part of the main flue, there may be only one oil receiver. It is possible to improve the cleaning workability and reduce the cost. In addition to this, it may be provided at any position of the oil droplet guideway provided in the lower part of the side flue. Further, the number of oil receivers to be provided is not limited to one or two, and may be three or more. Furthermore, it may be provided asymmetrically.

  The inclination direction and the inclination shape of each oil droplet guiding path can be appropriately changed according to the arrangement position of the oil receiver. The oil droplet guideway provided in the lower part of the main flue may be provided with an inclination in the front-rear direction instead of the frontage direction. For example, the front and rear sides of the sirocco fan in the front-rear width direction are inclined so that the front and rear sides are inclined in a substantially V shape, and the oil drop is guided to the oil receiver disposed below the oil drop guide path. A structure in which at least one or more flow holes are formed in the protruding portion of the oil receiving guideway located above the oil receiver so that the oil can flow down. The oil droplets flowing down from the fan casing of the sirocco fan or the inner wall of the main flue are guided by the concave portion having a V-shaped cross section, and then dropped and collected in the oil receiver from the above-mentioned dropping hole.

  The shape and size of the oil receiver are not limited to the embodiment, and may be other shapes or different sizes as long as the oil droplets derived from the oil droplet guiding path can be collected. For example, a tank shape may be used instead of a tray shape. Alternatively, it may be a plastic bag. In this case, the entire bag can be discarded, and workability is improved. Further, a handle, a recess, or the like may be provided to facilitate attachment / detachment. Furthermore, an oil receiver may be provided on the entire oil droplet guiding path. In this case, the oil droplet guiding path itself may be used as an oil receiver. In other words, the oil droplet guide path is detachable. In this way, the oil droplet guide way can be easily cleaned. Further, it is not necessary to incline the oil droplet guide path, and the degree of freedom in design is improved.

  The desorption structure of the oil receiver is not limited to the drawer shape, and other desorption structures may be adopted. For example, a structure that allows detachment in the vertical direction can be mentioned. Further, in the case of a drawer shape, the drawing direction is not limited to the front-rear direction, and it may be possible to draw in other directions such as a horizontal direction. Below the discharge port provided in the lower part of the fan casing, there is provided a gutter that receives the oily dirt discharged from the discharge port, and an oil drop guide path that extends oil droplets from the gutter toward the oil catch so that it can be guided. May be provided separately. The oil droplet guide path is configured as an inclined surface that is inclined to guide the oil droplets discharged from the discharge port of the fan casing to the oil receiver.

  The sirocco fan is an example of a suction device, and is not limited thereto, and other types of suction devices may be used. For example, the structure using a general propeller fan is mentioned. In this case, the above-described operation effect peculiar to the sirocco fan cannot be obtained, but other operation effects such as high smoke collection ability by the swirl flow and cleaning workability can be continuously obtained. The opening and the filter shape are not limited to a circular shape, and may be other shapes such as a square.

  In the first embodiment, as the suction device for the range hood 14, the sirocco fan 15 is arranged at the innermost part in the main flue 18b so that the rotational axis direction thereof substantially coincides with the front-rear direction. It is extremely compact, and an excellent effect of reducing the size of the range hood 14 can be obtained. However, on the other hand, the range hood 14 has not been sufficiently downsized in the vertical direction. The downsizing of the range hood 14 in the vertical direction is highly necessary not only from functional requirements such as installation space but also from an aesthetic point of view. That is, due to changes in housing conditions in recent years, the system kitchen 10 including the range hood 14 is not only required to have simple functionality, but also has an increasing demand for design of appearance, such as interior interiors. .

  In view of this point, the downsizing of the range hood 14 in the vertical direction can reduce the sense of volume and create an exhilarating feeling, which leads to an excellent design. However, in order to further reduce the size of the range hood 14 in the up-and-down direction, an effective method is to reduce the inclination angle of the guide surface 16d located at the lowermost position and lay it down. This method has the following problems.

  The guide surface 16d has a purpose of reliably capturing smoke and the like flowing in from below as described above and guiding it to the arcuate surface 16e continuous upward. However, in the structure in which the inclination angle of the guide surface 16d is reduced as described above, there is a possibility that smoke or the like flowing from below cannot be sufficiently captured. That is, smoke or the like flowing in from below is not sufficiently guided to the arcuate surface 16e that continues upward after hitting the guide surface 16d, and part of the smoke climbs over the side plate 16a from both sides of the guide surface 16d. There was a risk that it would flow out of the range hood 14. Therefore, in this embodiment, downsizing in the vertical direction is achieved without impairing the excellent operational effects including the high suction capability described in the first embodiment, so that both high design and space saving can be achieved. Provide configuration.

  As shown in FIG. 5, the range hood 14 in the present embodiment lays the guide surface 16 d at a smaller inclination angle than in the first embodiment. The inclination angle is, for example, 30 ° as a standing angle from the horizontal plane. Further, at both ends in the frontage direction from the guide surface 16d to the lower portion of the arcuate surface 16e, recesses 16f serving as a guide mechanism for smoke or the like recessed toward the back of the range hood 14 are provided. The concave portion 16f is made of, for example, chamfering, and the depth in the depth direction is deepest in the vicinity of the boundary between the guide surface 16d and the arcuate surface 16e, and the depth continuously decreases in the vertical direction. Gradual change.

  As shown in FIG. 6, the recess 16f is arranged so as to be located on both sides of the fan casing 15b arranged on the back side of the guide surface 16d, and does not interfere with the fan casing 15b. Yes. According to the guide plate 16b configured as described above, smoke that reaches the guide surface 16d from the lower stove cannot be guided due to a small inclination angle of the guide surface 16d, and smoke that tends to flow in the lateral direction. Is captured by the concave portion 16f provided on the side, and can be reliably corrected and guided along the concave portion 16f to the upper arcuate surface 16e.

  Therefore, even if the inclination angle of the guide surface 16d is reduced and the vertical size of the range hood 14 is reduced, smoke or the like does not flow out to the side of the range hood main body 14a, and the excellent effect described in the first embodiment is achieved. It is possible to achieve both an effect, an excellent design that reduces the volume and creates a refreshing feeling, and a space-saving property.

  In addition, this invention is not limited to the structure of a present Example, It can change suitably about the structure listed below. The recess may have a structure other than chamfering as long as smoke or the like can be corrected and guided to the upper arcuate surface. For example, a curved surface may be provided, or a simple groove may be provided. The depth of the recess is not particularly limited as long as smoke or the like can be corrected and guided to the upper arcuate surface. It does not have to be gradually changed, and it is not always necessary to deepen the vicinity of the boundary between the guide surface and the arcuate surface.

  In the present embodiment, the configuration in which the concave portion is implemented as the smoke guiding mechanism has been described. However, as long as smoke or the like can be corrected and guided on the upper arcuate surface, the concave portion is not necessarily required. A guide mechanism may be applied. For example, at least one of both end portions of the guide surface itself or the side plate adjacent to both end portions of the guide surface is provided with suction holes for sucking smoke or the like into the flue on the back surface and capable of guiding the correction. A configuration in which a gap is formed is exemplified. Also with this configuration, the same effect as the concave portion can be obtained. In this configuration, a filter may be attached to the suction hole.

  As described above, the guide plate 16b described in each of the above embodiments is simple with no irregularities on the inner surface, and can easily wipe off the adhered oil droplets and the like, and high cleaning workability is obtained. However, in the case of oil droplets firmly fixed, it may be difficult to completely clean the oil droplets only by wiping. In particular, the arcuate surface 16e at a higher position is hard to reach and is curved, so there is room for improvement in terms of cleaning workability compared to the guide surface 16d. In addition, it is difficult to clean the inner wall of the flue 18 and the sirocco fan 15. Therefore, in the present embodiment, such a range hood with improved cleaning workability is realized. The configuration will be described below.

  The range hood 14 according to the present embodiment is greatly characterized in that the arc-shaped surface 16e of the guide plate 16b can be detached from the guide surface 16d and the range hood main body 14a. That is, as shown in FIG. 7, the arcuate surface 16e is separate from the guide surface 16d and the side plate 16a. For example, a U-shaped support 22 is provided at the upper edge of the guide surface 16d, and the arcuate surface 16e. At the same time that one end of the hood is inserted into the receiver 22, the other end is screwed to the front edge of the range hood main body 14 a with a screw (not shown) so that the range hood 14 is detachably attached.

  According to the range hood 14 having the detachable arcuate surface 16e, when the arcuate surface 16e is to be cleaned, the arcuate surface 16e can be removed and the front and back thereof can be easily washed directly and directly. it can. Further, by removing the arcuate surface 16e, the guide plate 16b is greatly opened, so that the inner wall of the flue 18, the sirocco fan 15 and the like can be easily cleaned.

  Incidentally, in the first embodiment, as shown in FIG. 2, the filters 17 are mounted so as to protrude inward from the side plates 16a. If it does in this way, when removing the arc-shaped surface 16e which becomes substantially the same width as the space | interval of the side plates 16a below, the filter 17 on either side will interfere. Therefore, before removing the arcuate surface 16e downward, the filter 17 must be removed in advance, and the work becomes very troublesome. Further, as described above, the filter 17 includes an oil receiver (not shown) or an oil absorbing member that is integrally provided inside the filter 17, but it is possible to completely collect all the oil droplets that adhere to the filter 17 and flow down. In some cases, a part of the filter 17 flows down from the main body of the filter 17 to the side plate 16a.

  Therefore, in this embodiment, as shown in FIGS. 8 and 9, the lower end of the outer periphery of the substantially circular opening 16c provided in the side plate 16a in this embodiment is directed outward (side flue 18a side). In addition, a substantially L-shaped first step receiver 23a that protrudes at least as much as the thickness of the filter 17 is provided. On the other hand, at the upper end of the outer periphery of the opening 16c, an urging mechanism 23b capable of urging in the direction of the first step receiving portion 23a is provided on the inner side of the range hood main body 14a. In the present embodiment, the urging mechanism 23b is configured by a leaf spring that has two convex portions facing downward.

  Further, on both sides of the outer periphery of the opening 16c, second step receivers 23c each having a substantially L shape are provided so as to protrude toward the outside of the side plate 16a by at least the thickness of the filter 17 or more. At the upper end of the opening 16c provided with the urging mechanism 23b, a first drop-off prevention mechanism 24a formed by extending the side plate 16a is provided. On the other hand, a second drop-off prevention mechanism 24b is provided at the lower end of the opening 16c, in which a part of the protruding portion of the first step receiver 23a is recessed one step in the outer peripheral direction (downward) of the opening 16c. .

  The filter 17 has a substantially circular shape that is slightly smaller than the opening 16c, and a flat surface receiving portion 17a is provided on a part of the outer periphery of the filter 17, and the other portion of the outer periphery that is substantially opposite to the flat surface receiving portion 17a. A handle 17b that protrudes substantially to the surface side (suction side) is provided. Furthermore, the outer periphery of the filter 17 on the handle 17b side has a part of the width corresponding to a part of the depression width of the protruding portion of the first step receiver 23a, which is the second drop-off prevention mechanism 24b. It is narrowed.

  Next, the mounting state of the filter 17 in the configuration as described above will be described below. When the filter 17 is mounted, first, the handle 17b of the filter 17 is held, and the flat surface receiving portion 17a side is inserted into the back surface side of the first dropout prevention mechanism 24a at the upper end of the opening portion 16c. Then, the lower end side of the filter 17, that is, the handle 17 b side is inserted into the opening portion 16 c while pressing slightly upward so as to resist the downward biasing of the biasing mechanism 23 b in contact. Then, the outer periphery of the filter 17 is regulated to abut against both the step receivers 23a and 23c, and the outer periphery of the lower end of the filter 17 is a recess in the protruding portion of the first step receiver 23a, which is the second drop prevention mechanism 24b. The fitting is completed by being abutted and urged against the step receiver 23a by the urging mechanism 23b.

  FIG. 10 shows the filter 17 as viewed from the back side (side flue 18a side when attached to the side plate 16a). In the figure, the substantially circular filter 17 has four substantially fan-shaped areas A1 to A4 divided by two normal lines with respect to a circle centered on the substantially central portion of the ventilation surface. A plurality of rectangular plate-like tongue pieces 17d cut and raised on the back side (front side of the paper surface) are formed over the entire surface of the filter 17. Further, the direction of cutting and raising the tongue piece 17d is unified for each of the areas A1 to A4. In the region A1, the cut and raised end is oriented on the upper side of the paper, in the region A2, the cut and raised end is oriented on the left side of the paper, and in the region A3, the cut and raised end is oriented on the lower side of the paper. In A4, the cut and raised edge is oriented on the right side of the drawing. That is, the direction of the cut-and-raised end in each of the areas A1 to A4 is formed to be counterclockwise on the paper surface.

  In the same figure, smoke etc. S is shown with the broken-line arrow. Note that the smoke S or the like swirls inside the side plate 16a (the front side of the filter 17) and swirls clockwise. That is, the turning direction is opposite to the orientation direction of the cut and raised end of the tongue piece 17d. Thereby, as shown in the cross section in the same figure, the advancing direction of the smoke S or the like sucked to the outside while turning in all the areas A1 to A4 and the perpendicular direction of the tongue piece 17d can be made substantially coincident. Therefore, the smoke or the like S can be caused to collide with the tongue piece 17d straight, and thereafter the smoke or the like S can be sucked from the gap between the cut and raised end and the filter surface. The filter 17 shown in the figure is a filter 17 attached to the left side plate 16a. On the other hand, in the filter 17 attached to the right side plate 16a, in order to cause the smoke S or the like to collide with the tongue piece 17a straightly, the tongue piece 17d may be formed so that the cut and raised end is oriented clockwise.

  According to the configuration of the present embodiment described above, the filter 17 is mounted on the inner side of the flue 18a rather than the surface of the side plate 16a. Therefore, the filter 17 does not protrude from the surface of the side plate 16a, thereby hindering cleaning of the side plate 16a. Or obstructing the work of detaching the arcuate surface 16e. Moreover, the dripping of the oil droplet below from the filter 17 can be suppressed. Furthermore, the filter 17 can be attached and detached very easily by the handle 17b without using any tools, and workability can be improved. Furthermore, since the drop prevention mechanisms 24a and 24b are provided, it is possible to reliably prevent the filter 17 from dropping during use. Moreover, since smoke etc. S can collide with the tongue piece 17a substantially perpendicularly, the oil dust component contained in smoke etc. S can be made to adhere to the tongue piece 17a efficiently. Therefore, the recovery efficiency of the oil dust component in the filter 17 can be improved.

  In addition, this invention is not limited to the structure of a present Example, About the structure listed below, it can change suitably. The shape, the installation position, and the number of installation of the step receiver are not limited, and may be other shapes, positions, and numbers as long as the filter position can be regulated and held. Similarly, the shape, type, installation position, and number of installation of the urging means are not limited, and may be other shapes, types, positions, and numbers as long as they can be urged to hold the filter. . For example, a structure in which the step receiving and the urging means are arranged upside down can be mentioned. Further, the second step receiving may be omitted. Furthermore, elastic rubber may be adopted as the biasing means instead of the leaf spring.

  Furthermore, a step receiver may be provided on the front periphery of the outer periphery of the opening, or a structure other than the step receiver may be employed. For example, a structure in which a protrusion is provided on one side of the opening and the filter and a protrusion receiver is provided on the other side. The shape of the opening and the filter is not limited to a circle, and may be other shapes such as a square, and the normal lines that divide into a plurality of regions are not limited to two, but may be one or more than three. good. The drop-off prevention mechanism may adopt another structure as long as the filter drop-off prevention function is obtained. For example, the example which makes the 1st drop-off prevention mechanism the same structure as the 2nd drop-off prevention mechanism is given. Alternatively, on the contrary, the second drop-off prevention mechanism may have the same structure as the first drop-off prevention mechanism.

  However, in this case, the side plate extension length as the drop-off prevention mechanism needs to be a length that can be inserted when the filter is pressed against the biasing mechanism. Either one or both of the dropout prevention mechanisms may be omitted. Since there is an urging force of the urging mechanism and a suction force during operation of the range hood, even if omitted, a certain drop-off preventing effect can be obtained. The urging direction by the urging mechanism is not limited to the downward direction. For example, the urging direction may be urged diagonally backward or backward. You may make it fix by methods other than an urging | biasing mechanism. For example, a screw is provided on the filter outer periphery and a receiver provided on the side plate, and the filter itself is rotated and screwed. Alternatively, a structure that is locked by a hook may be used. Furthermore, a screw fixing method may be used as in the first embodiment.

  In this case, the advantage of the ease of the detaching operation is lost, but the effect obtained by not protruding from the side plate can be continuously obtained. The urging mechanism and the step receiver may be provided so as to protrude inward of the guide plate side of the side plate. In this case, since the filter protrudes from the side plate and is fixed, the problem associated therewith remains, but the advantage of easy attachment / detachment can still be obtained. The opening and the filter may be provided with a regulating shape that abuts and interferes except when mounted in the normal position in the rotational direction. According to this, erroneous mounting at the rotational position of the filter can be prevented.

  The filter 17 attached to the opening 16c in the third embodiment has a structure that does not protrude from the surface of the side plate 16a, and oil droplets can be suppressed from dropping downward from the protruding portion of the filter 17. However, there is still a problem that oil droplets adhering to the filter 17 flow down along the side plate 16a below the filter 17. This is a particular problem in the case of another embodiment in which the filter 17 is provided protruding from the side plate 16a. Therefore, in the present embodiment, a configuration of a treatment structure for oil droplets flowing down from around the filter 17 for improving these points will be described.

  In the range hood 14 of the present embodiment, as shown in FIG. 8, in the filter 17 mounting structure in the third embodiment, oil droplets flowing down from the filter 17 are applied to the lower end of the opening 16c and the first step receiver 23a. , Oil droplet guiding paths 25a and 25b are provided for guiding the side flue 18a. In other words, the oil droplet guideway provided in the former is a cut bend 25a as an inclined surface, which has a substantially opening 16c width and is punched and bent so that the upper end side is inclined at an angle below horizontal in the side flue 18a. The oil droplet guide path provided in the latter is a hole 25b provided through at least a part of the projecting portion of the first step receiver 23a.

  According to the cut bend 25a, oil droplets flowing down from the outer surface side (suction side) of the filter 17 or the side plate 16a around the filter 17 through the side plate 16a can be easily and from the bent portion into the side flue 18a. It can be reliably guided and can be recovered in the oil receiver 20 while suppressing the downward flow of the side plate 16a. Similarly, according to the hole 25b, the side plate 16a (the inner wall of the side flue 18a) flows down from the inner surface side (the flue 18a side) of the filter 17 or the side plate 16a around the filter 17 and reaches the first step receiver 23a. Without causing oil droplets to flow from the opening 16c to the outer surface of the side plate 16a, the oil droplets can be easily and reliably guided to the oil droplet guiding path 19a below the side flue 18a and collected in the oil receiver 20.

  In addition, this invention is not limited to the structure of a present Example, About the structure listed below, it can change suitably. In addition to the cut bend 25a, the lower end side section 25e may be inclined. Instead of the cut bend, an elongated hole 25d having a substantially opening width in which the upper end side section 25c is inclined may be provided. Alternatively, it may be a simple through hole having no inclination. Only one of the cut bend and the hole may be provided. The oil droplet guide path provided in the first step receiver may be a notch provided inward from the end of the step receiver, instead of a hole. Two or more cut bends may be arranged in the vertical direction instead of only one. In this case, the individual cut bends do not necessarily have to be provided over the entire width of the opening. For example, each stage covers only a part in the width direction, and each stage covers the entire width. Also good.

  In the present embodiment, the case where the present invention is applied to the filter mounting structure in the third embodiment has been described. However, the present invention may be applied to the filter mounting structure in the first embodiment. That is, as shown in FIG. 11, in the filter mounting structure, the side plate portion covered with the filter below the opening and the side plate portion below the filter have cut bends 26a and 26b or holes 26c whose upper end side sections are inclined. 26d is provided. Also by this, the oil droplet around a filter can be reliably collect | recovered like the above. In addition to the cut bends 26a and 26b, the lower end side sections 26e and 26f may be inclined. Further, the side plate portion covered with the filter at the lower part of the opening may be a tapered surface that is not simply a cut bend or a hole but is simply inclined with the lower edge of the opening toward the lower side of the side flue.
