However, in this structure, the presence of the left and right side plates results in poor visibility from the left and right sides, and the presence of the left and right side plates and the front plate so as to protrude to the cooker side causes a sense of pressure on the cooker. Furthermore, since recessed portions are formed around the rectifying plate, there are many irregularities and the cleanliness is poor. Therefore, it is considered to eliminate the recesses around the rectifier plate. However, if the recesses around the rectifier plate are simply eliminated, the above-mentioned rising oil fume and the like cannot be accepted, and there is a problem that the rising oil fume and the like cannot be captured completely and exhausted to the outside of the range hood. Leakage issue.

Therefore, in the present invention, there is provided an exhaust hood which can eliminate those who put pressure on a cooker, such as left and right side plates, and those who form recesses around the fairing plate, and efficiently capture rising soot and the like.

In order to solve the above-mentioned problem, a range hood is provided, which is arranged above a cooking device and collects the fumes generated by cooking. The range hood is provided with: a body having an air blower inside; and a cover portion, which The oblique portion of the rectangular flat plate inclined as it goes from the back side toward the front side and upwards is composed of an eaves portion that extends from the upper end of the oblique portion toward the front side to capture oil fume; and a rectangular fairing plate, larger than The opening portion of the inclined surface communicating with the blower forms a suction opening for the air flow generated by the blower between the cover portion and the edge portion. The cover portion has a side open and the end portion on the front side of the eave portion is located closer to the fairing plate. The front end is closer to the front side. The angle θ1 formed by the inclined surface and the horizontal plane, the angle θ2 formed by the fairing plate and the horizontal plane, and the angle θ3 formed by the eaves and the horizontal plane have the relationship of formula (1).

0 <θ3 <θ2 <θ1 ...... (1)

Thereby, it is possible to provide a range hood, that is, the rectifying plate is installed at an inclination different from that of the inclined surface portion, so that the upper suction port is larger than the lower suction port and has a larger suction flow rate. The upper side extends obliquely, and the attractive force effectively acts on the soot that is leaking to the upper side of the range hood, and can efficiently capture the soot. That is, by elongating the eaves portion toward the upper side, the suction force from the suction opening formed by the gap between the fairing plate and the cover portion is more easily transmitted to the upper area than when the eaves portion is horizontal, and can be efficiently performed. Capturing soot that will leak upwards.

In addition, the rectifying plate is installed at a different inclination from the inclined surface so that the distance between the upper end side and the inclined surface is greater than the distance between the upper end side and the inclined surface in front of the inclined surface. Further, the action of oil fume, etc., which is to be widely diffused, becomes stronger as it is sucked upward, thereby reducing leakage to the left and right directions of the cover.

Furthermore, there are no side panels or the like on the left and right sides of the cover portion so that the fairing plate can be viewed from the side, and the eaves portion extends obliquely upward, so that it does not give a sense of pressure to the cook. Since there are no recesses around the fairing plate and With less bumps, it can provide a range hood with high cleanliness.

Furthermore, the cover portion may have a bottom surface portion extending from the lower end of the inclined surface portion, and the angle θ4 formed by the bottom surface portion and the horizontal plane may have a relationship of the formula (2).

0 <θ4 <θ1 ............ (2)

Thereby, the bottom surface is inclined toward the front side and upward, and when the oil fume (for example, grill exhaust) generated from the back side of the cooker contacts the bottom surface, it is smoothly guided to the inclined surface, which can reduce the oil fume from the bottom surface. Leaked to the outside of the range hood left and right.

In addition, it may be further provided with an oil storage tank having a left and right width larger than the left and right widths of the rectification plate, detachably provided on the cover portion at the lower end side of the rectification plate, and near the end portion of the oil storage tank and the rectification plate. Suction ports are formed therebetween, and the angle θ5 formed by the bottom surface of the oil storage tank and the horizontal plane has a relationship of the formula (3).

Thereby, the bottom surface of the oil storage tank is inclined toward the front side and upward, and the upper end of the oil storage tank forms a suction port between the rectification plate and the oil fume in contact with the bottom surface of the oil storage tank along the bottom surface of the inclined oil storage tank smoothly. It is guided upward and sucked into the suction port efficiently.

As described above, according to the present invention, it is possible to provide a range hood that eliminates the pressure on the cooker, such as left and right side plates, and the formation of recesses around the fairing plate, and efficiently captures rising fumes and the like.

<First Embodiment>

Referring to FIGS. 1 to 5, the range hood 100 of this embodiment will be described. The cooker hood 100 is a cooker hood (not shown) provided above the cooker (not shown). The cooker hood 100 is a cooker hood that collects oil fume and steam generated by cooking and rises, and exhausts it to the outside through a duct (not shown). The range hood 100 includes a main body 10 connected to a duct, a cover portion 20 that collects oil fume, and the like, and a rectifying plate 30 that forms an air inlet 50 for sucking air between the cover portion 20 and the cover portion 20.

The main body 10 has an air blower 11 inside which generates air flow by rotating. The blower 11 is preferably a multi-wing blower with high static pressure. When the main body 10 is installed above the cooking device, the main body 10 is connected on the upper surface to a duct provided in the installation place, and is connected to a duct cover D covering the duct. In the main body 10, the upper surface and the rear surface are substantially flat, the upper surface is formed parallel to the ceiling, and the rear surface is formed parallel (or connected) to the wall, so they intersect at right angles to each other. In the main body 10, the main portion on the front side is formed so as to be inclined upward from the back side (front side / wall side) toward the front side (front side) when installed. Thereby, the approximate external shape of the main body 10 when viewed from the side is a right-angled triangle, and a part of the oblique side of the triangle is opened, and the cover portion 20 is provided so as to cover the opening.

The cover portion 20 includes an inclined surface portion 21 that is a rectangular flat plate and an eaves portion 22 that extends from the upper end 25 of the inclined surface portion 21 toward the front side (front side). The opening that becomes the main part of the front side of the body 10 is covered by the inclined surface portion 21 of the rectangular flat plate. As described above, when it is installed, it is formed so as to be inclined upward from the back side toward the front side. Therefore, the inclined surface portion 21 is provided. Time is a flat surface that slopes upward as it goes from the back toward the front. As shown in FIGS. 3 and 4, the inclined surface portion 21 has an opening portion 24 at an upper portion of the center, and forms a flow path of the air flow generated by the blower 11. It is preferable to provide a filter for capturing oil in the opening 24. As described above, the inclined surface portion 21 is almost a flat surface except for the opening portion 24 and the fasteners for holding the fairing plate 30, and is in a form that is easy to clean even if oil is adhered. In addition, in the present embodiment, the switch 1 for adjusting the blower 11 and the switch 1 for adjusting the air volume are provided on the inclined surface portion 21.

The eaves portion 22 is formed of a flat surface that extends from the upper end 25 of the inclined surface portion 21 toward the front side. The eaves portion 22 is formed by being bent at the upper end 25 of the inclined surface portion 21 so as to have a gentle inclination (incline closer to the horizontal plane) than that of the inclined surface portion 21, and is formed by being extended in a plane. The eaves portion 22 is formed so as to have a substantially uniform width across the entire area in the left-right direction and the front-rear direction (direction from the back side to the front side). The eaves portion 22 itself has an elongated rectangular shape. In addition, the eaves portion 22 is formed with the same left and right width as the inclined surface portion 21, thereby spreading the suction force from the suction port to the upper area easily throughout the entire area in the left and right direction of the cover portion 20.

In addition, as in this embodiment, the cover portion 20 may further include a bottom surface portion 27 extending from the lower end 26 of the inclined surface portion 21. The bottom surface portion 27 is formed by being bent at a lower end 26 of the inclined surface portion 21 so as to be slightly inclined than the inclination of the inclined surface portion 21, and is formed by being extended in a plane. The bottom surface portion 27 is formed to cover the entire area in the left-right direction and the front-to-rear direction (direction from the back side to the front side) has a substantially uniform width. It is better to abut the wall when it is installed. The end portion of the bottom surface portion 27 contacts the wall. Face contact is particularly good. That is, it is preferable that the end portion of the bottom surface portion 27 is on the back surface side and is at the same level as the back surface of the main body 10. With the presence of the bottom surface portion 27, oil fume (for example, grill exhaust from the cooker) generated from the back side of the cooker can also be guided above (near the front side) the cover portion. The bottom surface portion 27 is formed with the same left and right width as the inclined surface portion 21, and thus, compared with the bottom surface portion provided horizontally throughout the entire area in the left-right direction of the cover portion 20, it is possible to play a role of guiding the oil fume above (near the front side) the cover portion. The effect. In addition, in the present embodiment, the bottom surface portion 27 is provided with an infrared light receiving portion 3 that receives the operation of the illumination 2 and the remote control.

In the cover portion of the conventional range hood, side plates are provided on the left and right in order to provide recesses for trapping oil fume and the like. As described above, the inclined surface portion 21, eaves portion 22, and bottom surface portion 27 of the cover portion 20 are provided. Each is composed of only a substantially flat surface, and does not include a member such as a side plate. Thereby, in the range hood 100, the side surface of the cover part 20 is opened, and when viewed from the side, the right side surface can be seen from the left side and the left side surface can be seen from the right side. Of course, the fairing plate 30 attached to the front surface of the cover part 20 can also be observed. Accordingly, it is possible to eliminate a person who feels pressure on a cooker, such as left and right side plates, and a person who has formed a recess around the fairing plate. That is, there are no side panels or the like on the left and right sides of the cover portion 20 so that the rectifying plate 30 can be viewed from the side without putting a sense of pressure on the cook. The rectifying plate 30 has no recesses around it and has less unevenness. An exhaust hood 100 with high cleanliness is provided.

The fairing plate 30 is a rectangular flat plate larger than the opening portion 24 provided on the inclined surface portion 21 and communicating with the blower 11. The front surface (front side) of the inclined surface portion 21 is provided to cover the opening portion 24 when viewed from the front. The fairing plate 30 is attached via a stopper provided on the inclined surface portion 21. An edge portion 31 serving as a flat plate of the fairing plate 30 forms a suction port 50 for sucking air between the edge portion 31 and the surface on the front side of the cover portion 20.

More specifically, the suction port 50 a is formed between the side end 34 located on the left and right edge portions 31 in the fairing plate 30 and the inclined surface portion 21, and is the upper end 32 (nearly) of the edge portion 31 located on the upper side in the fairing plate 30. An end portion on the front side) forms a suction port 50 b between the inclined surface portion 21 and the eaves portion 22, and forms a suction port 50 c between the inclined portion 21 and the inclined surface portion 21 as a lower end 33 of the edge portion 31 located on the lower side in the fairing plate 30. The upper end 32 and the lower end 33 are arranged parallel to the inclined surface portion 21 in a cross section with respect to a direction perpendicular to the inflow direction of the air in the air inlet 50b and the air inlet 50c, and thus are rectangular. In addition, since the distance between the upper end 32 and the inclined surface portion 21 is larger than the distance between the lower end 33 and the inclined surface portion 21, the area of the suction port 50b is larger than the area of the suction port 50c. Thereby, the amount of air sucked in the suction port 50b is larger than that of the suction port 50c.

Since the distance between the upper end 32 and the inclined surface portion 21 is greater than the distance between the lower end 33 and the inclined surface portion 21, the cross section in the direction perpendicular to the air inflow direction in the suction port 50a is not rectangular, but is on the lower end 33 side. A substantially triangular shape that is smaller and becomes larger on the upper end 32 side. In this way, the amount of air sucked in the suction port 50a is not uniform in the vertical direction, and changes so as to gradually increase as it moves from the lower end 33 to the upper end 32.

In addition, the distance between the upper end 32 of the fairing plate 30 and the inclined surface portion 21 is greater than the distance of the lower end 33 and the inclined surface portion 21, but the upper end 32 which is the end near the front side of the fairing plate 30 is located at the end portion 23 of the eaves portion 22. (The front end portion of the eaves portion 22) is located closer to the back side (back side). That is, the end portion 23 of the eaves portion 22 is located closer to the front side than the upper end 32 which is the end portion on the front side of the fairing plate 30. Thereby, the eaves part 22 can prevent the spread of the oil fume which is going to rise from the upper end 32 of the fairing plate 30.

In the range hood 100, an oil storage tank 40 may be further provided on the lower end 33 side of the fairing plate 30 so as to be attachable and detachable to the cover portion 20. The upper end 42 (near front side end portion) of the oil storage tank 40 is located closer to the front side than the lower end 33 of the fairing plate 30. The oil storage tank 40 has a wider left and right width than the right and left widths of the rectifying plate 30, so that even if the oil adhered to the rectifying plate 30 drops from the lower end 33, the oil can be received and recovered. A suction port 50 d is formed between the upper end 42 (near-front end portion) of the oil storage tank 40 and the rectifying plate 30, and the suction port 50 d and the suction port 50 c between the lower end 33 of the rectifying plate 30 and the inclined surface portion 21 communicate with each other. The oil storage tank 40 includes, as a bottom surface 41, a surface on which oil fume coming from the surface of the oil storage tank 40 that mainly comes into contact.

Referring to FIG. 5, when the range hood 100 is installed, the inclined surface portion 21, the fairing plate 30, the eaves portion 22, the bottom surface portion 27, and the bottom surface 41 of the oil storage tank 40 are inclined such that they are inclined upward from the back side toward the front side. The relationship of the inclination will be described. Here, as shown in this figure (B), the angle formed by the inclined surface portion 21 and the horizontal plane is set as angle θ1, the angle formed by the fairing plate 30 and the horizontal plane is set as angle θ2, and the eaves portion 22 is formed by the horizontal plane. The angle is an angle θ3, the angle formed by the bottom surface portion 27 and the horizontal plane is angle θ4, and the angle formed by the bottom surface 41 of the oil storage tank 40 and the horizontal plane is angle θ5.

In the range hood 100, the angle θ1 formed by the inclined surface portion 21 and the horizontal plane, the angle θ2 formed by the rectifying plate 30 and the horizontal plane, and the angle θ3 formed by the eaves 22 and the horizontal plane have a relationship of the formula (1).

0 <θ3 <θ2 <θ1 ...... (1)

That is, there is a relationship between the angle θ2 formed by the rectifying plate 30 and the horizontal plane <the angle θ1 formed by the inclined surface 21 and the horizontal plane, and the rectifying plate 30 is installed at a different inclination from the inclined surface 21 so that the upper end 32 and the inclined surface 21 The distance is larger than the distance between the lower end 33 and the inclined surface portion 21. Thereby, the air intake amount of the suction port 50b on the upper side of the fairing plate 30 becomes larger than that of the lower suction port 50c, and the air intake amount of the suction ports 50a of the left and right sides of the fairing plate 30 increases from the lower end 33 to the upper end. The way 32 moves and grows changes. In this way, in combination with the action of oil fume or the like that is to be widely diffused as it flies upwards, the amount of inhalation increases as the suction port moves from the lower side to the upper side, so that it is possible to reduce leakage in the left-right direction of the cover portion.

Furthermore, the range hood 100 has a relationship between the angle θ3 formed by the eaves portion 22 and the horizontal plane <the angle θ2 formed by the fairing plate 30 and the horizontal plane, and the eaves portion 22 has a slope that is gentler than that of the inclined surface portion 21 (close to the horizontal plane) It is formed by bending the upper end 25 of the inclined surface portion 21 and extending it in a plane. If the angle θ3 formed by the eaves portion 22 and the horizontal plane is equal to or greater than the angle θ2 formed by the rectification plate 30 and the horizontal plane, the upper end 32 of the rectifying plate 30 cannot form the eaves portion 22 and the suction port 50b, so that oil fume cannot be efficiently collected.

The range hood 100 has a relationship of 0 <the angle θ3 formed by the eaves portion 22 and the horizontal plane, and the eaves portion 22 is inclined upward from the back side toward the front side. As described above, by having the relationship of 0 <angle θ3 <angle θ2, the attractive force effectively acts on the oil fume and the like which are to be leaked to the upper side of the range hood 100, and the oil fume can be efficiently collected. That is, as the eaves portion 22 extends obliquely upward, the suction force from the suction port 50b formed by the gap between the fairing plate 30 and the cover portion 20 is more easily transmitted to the upper area than when the eaves portion 22 is horizontal. , Can efficiently capture oil fume to leak upwards. In addition, since the eaves portion 22 extends obliquely upward, there is little pressure on the cook.

Further, in the range hood 100, when the bottom surface portion 27 is provided, the angle θ4 formed by the bottom surface portion 27 and the horizontal plane and the angle θ1 formed by the inclined surface portion 21 and the horizontal plane may have a relationship of the formula (2).

0 <θ4 <θ1 ............ (2)

Thereby, when the bottom surface portion 27 is inclined toward the front side and upward, when oil fume (for example, grill exhaust) generated from the back side of the cooker contacts the bottom surface portion 27, it is smoothly guided to the inclined surface portion 21, which can reduce oil fume. It leaks from the left and right of the bottom surface portion 27 to the outside of the range hood. In addition, the bottom surface portion 27 is formed at a lower slope than the inclined surface portion 21 by being bent at the lower end 26 of the inclined surface portion 21 and is formed by being extended in a plane, thereby ensuring a wide inner side (rear side / The space between the wall side) and the cooking device can ensure a good usability without bringing a sense of pressure on the user.

In addition, when the range hood 100 is provided with the oil storage tank 40, the angle θ5 formed by the bottom surface 41 of the oil storage tank 40 and the horizontal plane and the angle θ2 formed by the rectifying plate 30 and the horizontal plane may have a relationship of the formula (3).

Thereby, the bottom surface 41 of the oil storage tank 40 is inclined toward the front side and upward, and the upper end 42 of the oil storage tank 40 forms a suction port 50d between the rectifier plate 30. As a result, oil fume and the like that come into contact with the bottom surface 41 of the oil storage tank 40 follow The bottom surface 41 of the inclined oil storage tank 40 is smoothly guided upward, and is efficiently sucked into the suction port 50d. In addition, since the angle θ5 of the bottom surface 41 of the oil storage tank 40 is equal to or less than the angle θ2 of the fairing plate 30, the step between the lower end of the bottom surface 41 of the oil storage tank 40 and the inclined surface portion 21 can be reduced, and the oil smoke rising along the cover portion is blocked ( The conflict with the step difference is reduced, and the phenomenon that the oil fume is blocked (conflict with the step difference) and spread to the left and right can be reduced.

The angle formed by the tangent line and the horizontal plane in the lower end 26 of the inclined surface part 21 of the bottom surface part 27A and the angle θ1 formed by the inclined surface part 21 and the horizontal plane are the same. Therefore, the bottom surface portion 27A is curved toward the wall side with a large curvature and abuts against the wall surface. In addition, as shown in this figure (B), the angle θ4 formed by the bottom surface portion 27A and the horizontal plane is formed by a straight line and a horizontal plane that connect the lower end 26 of the inclined surface portion 21 that is the root of the bottom surface portion 27A and the front end of the bottom surface portion 27A. angle.

In this modification, the angle formed by the inclined surface portion 21 and the horizontal plane is also set as angle θ1, the angle formed by the fairing plate 30 and the horizontal plane is set as angle θ2, and the angle formed by the eaves portion 22A and the horizontal plane is set as angle θ3. Let the angle formed by the bottom surface 27A and the horizontal plane be the angle θ4, and the angle formed by the bottom surface 41 of the oil storage tank 40 and the horizontal plane be the angle θ5, the above-mentioned formulas (1), (2), and (3) Relationship. Thereby, the fairing plate 30 is installed at a different inclination from the inclined surface portion 21, so that the upper suction opening is larger than the lower suction opening and the suction flow rate is larger, and the eaves portion 22A surrounds the upper end 32 of the fairing plate 30. By forming the suction port, the suction force can effectively act on the fume and the like which are to be leaked to the upper side of the range hood, and it is possible to provide the range hood which can efficiently capture the range of fumes.
