However, in such a configuration, the right and left side plates make the view from the left and right poor, and the presence of the left and right side plates and the front plate so as to protrude to the cook side gives a sense of oppression to the cook. I was Furthermore, since the concave portion is formed around the current plate, the unevenness is large and the cleaning property is poor. Therefore, it is conceivable to eliminate the concave portion around the current plate.However, if the concave portion around the current plate is simply eliminated, the above-mentioned rising oil smoke and the like cannot be received, and the rising oil smoke and the like cannot be received. There was a problem that it could not be collected and leaked to the outside of the range hood.
Therefore, in the present invention, a range hood capable of efficiently collecting rising oil fumes and the like is provided, while eliminating the one that gives a feeling of pressure to the cook such as the left and right side plates and the one that forms a recess around the rectifying plate. provide.

In order to solve the above-mentioned problem, a range hood that is installed above a cooker and collects oil smoke generated by cooking is provided, and a main body having a blower therein, and when installed, from a back side to a front side. A hood portion for collecting oily smoke, which is provided on the inclined surface portion, comprising a rectangular flat plate inclined surface portion and an eave portion bent from the upper end of the inclined surface portion toward the front side and extending toward the front side. A rectangular straightening plate that is larger than the opening communicating with the blower and that forms a suction port for the flow of air generated by the blower between the hood and the edge, and the side of the hood is open. The end on the near side of the eave portion is located on the near side with respect to the end on the near side of the current plate, the angle θ1 between the inclined surface portion and the horizontal surface, the angle θ2 between the current plate and the horizontal surface, and the eave portion. The angle θ3 with the horizontal plane has the relationship of equation (1) Range hood is provided.
0 <θ3 <θ2 <θ1 (1) According to this, since the rectifying plate is attached at a different inclination angle from the inclined surface portion, the suction flow rate of the upper suction port is larger than that of the lower suction port. And the eaves extend upward and incline, so that effective suction works on oil smoke and the like that is leaking to the upper side of the range hood, and efficiently collects oil smoke. A range hood that can be used can be provided. That is, since the eaves extend upward and incline, the suction force from the suction opening formed by the gap between the rectifying plate and the hood increases the upward force as compared with the case where the eaves are horizontal. It becomes easy to be transmitted to the area, and it becomes possible to efficiently collect oil smoke that tends to leak upward.
In addition, the current plate is attached at a different inclination angle from the inclined surface so that the distance from the inclined surface is larger at the upper end side than at the lower end side in front of the inclined surface portion. Since it is possible to inhale more strongly as it goes upward in accordance with the behavior of oil smoke or the like to be tried, it is possible to reduce leakage in the left and right direction of the hood.
Further, since there is no side plate or the like on the left and right side surfaces of the hood portion so that the rectifying plate can be visually recognized from the side surface, the eaves portion is inclined upward and extends, giving a sense of oppression to the cook. Since there is no dent and there are no recesses around the current plate, there is little unevenness, so that a range hood with high cleaning performance can be provided.

Further, the hood portion may further have a bottom surface portion extending from a lower end of the inclined surface portion, and an angle θ4 formed by the bottom surface portion with a horizontal plane may have a relationship represented by Expression (2).
0 <θ4 <θ1 (2) According to this, since the bottom portion is inclined upward toward the near side, oil smoke (for example, grill exhaust) generated from the back side of the cooking device is reduced to the bottom surface. When it comes into contact with the portion, the guide is smoothly guided to the inclined surface portion, and leakage of oil smoke from the left and right sides of the bottom portion to the outside of the range hood can be reduced.

Furthermore, it has a left-right width larger than the left-right width of the current plate, and further includes an oil receiver detachably provided on the hood portion at the lower end side of the current plate, between the front end of the oil receiver and the current plate. The angle θ5 that forms the suction port and forms the bottom surface of the oil receiver with the horizontal plane may have a relationship represented by the following expression (3).
0 <θ5 ≦ θ2 (3) According to this, the bottom surface of the oil pan is inclined upward toward the near side, and the upper end of the oil pan forms a suction port with the rectifying plate. Oil smoke or the like that has come into contact with the bottom surface of the oil pan is guided upward smoothly along the inclined bottom surface of the oil pan, and is efficiently sucked into the suction port.

  As described above, according to the present invention, it is possible to eliminate a thing that gives a feeling of pressure to the cook such as the left and right side plates and a thing that forms a concave portion around the current plate, and efficiently removes rising oil smoke and the like. A range hood to collect can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First embodiment>
The range hood 100 according to the present embodiment will be described with reference to FIGS. The range hood 100 is installed above a cooker (not shown), collects oil smoke and steam generated by cooking and rises, and exhausts the air outside through a duct (not shown). It is. The range hood 100 includes a main body 10 connected to a duct, a hood portion 20 for collecting oily smoke and the like, and a rectifying plate 30 forming a suction port 50 for sucking air between the hood portion 20.

  The main body 10 has a blower 11 inside which generates a flow of air by rotating. The blower 11 is preferably a sirocco fan having a high static pressure. When the main body 10 is installed above the cooker, the main body 10 is connected to a duct provided at the installation location on the upper surface and is connected to a duct cover D that covers the duct. The main body 10 is formed so that 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 so as to be in contact with) the wall. The main body 10 is formed so as to open upward at a main part on the front side so as to be inclined upward from the back side (back side / wall side) toward the front side (front side) when installed. I have. Therefore, the general outer shape of the main body 10 in a side view is a right-angled triangle, and the hood portion 20 is provided so that the oblique side of the triangle is open and covers the opening.

  The hood portion 20 includes an inclined surface portion 21 which is a rectangular flat plate, and an eave portion 22 which extends from an upper end 25 of the inclined surface portion 21 toward the near side (front side). The opening serving as a main portion on the front side of the main body 10 is covered with the inclined surface 21 of a rectangular flat plate, and as described above, when installed, is inclined upward from the back side toward the front side when installed. Therefore, when the inclined surface portion 21 is installed, the inclined surface portion 21 forms a plane that is inclined upward from the back side toward the front side. As shown in FIG. 3 and FIG. 4, the inclined surface portion 21 has an opening 24 at the upper center, and forms a flow path of the flow of the air generated by the blower 11. Preferably, the opening 24 is provided with a filter for capturing oil. As described above, the inclined surface portion 21 is formed of substantially only a flat surface except for the opening portion 24 and the fastener for holding the current plate 30, and is in a form that is easy to clean even if oil adheres. ing. In the present embodiment, the switch 1 for adjusting the on / off of the blower 11 and the air volume is provided on the inclined surface portion 21.

  The eaves portion 22 is formed of a flat surface that bends and extends from the upper end 25 of the inclined surface portion 21 to the near side. The eaves portion 22 is bent at the upper end 25 of the inclined surface portion 21 so as to form a gentler inclination (inclination closer to the horizontal plane) than the inclination of the inclined surface portion 21, and is formed so that the plane extends. The eaves portion 22 is formed so that the front-rear direction (the direction from the back side to the front side) has substantially the same width over the entire region in the left-right direction, and the eaves portion 22 itself has a long thin rectangular shape. Further, since the eaves portion 22 has the same left and right width as the inclined surface portion 21, the suction force from the suction port is easily transmitted to the upper region over the entire left and right direction of the hood portion 20.

  The hood portion 20 may further include a bottom surface portion 27 extending from the lower end 26 of the inclined surface portion 21 as in the present embodiment. The bottom surface portion 27 is bent at the lower end 26 of the inclined surface portion 21 so as to form a gentler inclination than the inclination of the inclined surface portion 21, and is formed so as to extend a plane. The bottom surface portion 27 is formed so as to have substantially the same width in the front-rear direction (direction from the back side to the near side) over the entire region in the left-right direction, and it is preferable that the bottom portion 27 be in contact with a wall when installed. It is particularly preferred that the part in contact with the wall be in surface contact. That is, it is preferable that the end of the bottom portion 27 be flush with the rear surface of the main body 10 on the rear surface side. The presence of the bottom portion 27 allows oil smoke (for example, grill exhaust of the cooking device) generated from the back side of the cooking device to be guided to the upper side (front side) of the hood portion. Since the bottom portion 27 has the same left and right width as the inclined surface portion 21, it is possible to exhibit an effect of guiding the oil smoke to the upper side (front side) of the hood portion, rather than providing the bottom portion horizontally over the entire left and right direction of the hood portion 20. it can. In this embodiment, the bottom surface 27 is provided with the illumination 2 and the infrared receiving unit 3 for receiving a remote control operation.

  In the hood portion of the conventional range hood, side plates are provided on the left and right to provide a concave portion for receiving and collecting oil smoke and the like. As described above, the inclined surface portion 21, the eaves portion 22, and the bottom portion 27 of the hood portion 20 are provided. Are generally composed only of planes and do not include members such as side plates. Therefore, in the range hood 100, the side surface of the hood portion 20 is open, so that a side view can be seen from the left side to the right side and from the right side to the left side. Of course, the rectifying plate 30 attached to the front surface of the hood portion 20 can also be visually recognized. Thus, it is possible to eliminate a member that gives a feeling of pressure to the cook such as the left and right side plates and a member that forms a recess around the current plate. That is, there is no side plate or the like on the left and right side surfaces of the hood portion 20 so that the current plate 30 can be visually recognized from the side surface, so that the cook does not have a feeling of oppression, there is no concave portion around the current plate 30 and there are few irregularities. Therefore, the range hood 100 having high cleaning property can be provided.

  The current plate 30 is a rectangular flat plate larger than the opening 24 communicating with the blower 11 provided on the inclined surface 21, and is provided on the front surface (front side) of the inclined surface 21 so as to cover the opening 24 in a front view. . The current plate 30 is attached via a clasp provided on the inclined surface portion 21. An edge portion 31 of the flat plate, which is the current plate 30, forms a suction port 50 for sucking air between the flat portion 31 and the front surface of the hood portion 20.

  More specifically, the side end 34 that is the edge portion 31 located on the left and right sides of the current plate 30 forms a suction port 50a with the inclined surface portion 21, and the upper edge portion 31 of the current plate 30 A certain upper end 32 (an end on the near side) forms a suction port 50 b between the inclined surface portion 21 and the eave portion 22, and a lower end 33, which is the lower edge portion 31 of the straightening plate 30, is formed by the inclined surface portion 21. And the suction port 50c is formed. The cross section of the suction port 50b and the suction port 50c in a direction perpendicular to the air inflow direction is rectangular because the upper end 32 and the lower end 33 are provided in parallel with the inclined surface portion 21. Further, 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. Therefore, the air suction amount of 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 21 is greater than the distance between the lower end 33 and the inclined surface 21, the cross section of the suction port 50 a in the direction perpendicular to the air inflow direction is not rectangular but smaller at the lower end 33. It forms a generally triangular shape that increases on the upper end 32 side. Then, the air suction amount of the suction port 50a is not uniform in the up-down direction, and changes so as to gradually increase from the lower end 33 to the upper end 32.

  Although the distance between the upper end 32 of the rectifying plate 30 and the inclined surface portion 21 is provided to be larger than the distance between the lower end 33 and the inclined surface portion 21, the upper end 32 which is the front end of the rectifying plate 30 is It is located on the back side (back side) from the end 23 (the front end of the eaves 22). That is, the end portion 23 of the eave portion 22 is located on the near side with respect to the upper end 32 which is the end portion on the near side of the current plate 30. Thereby, the diffusion of the oil smoke that tends to rise from the upper end 32 of the current plate 30 can be prevented by the eave portion 22.

  The range hood 100 may further include an oil receiver 40 detachably mounted on the hood 20 on the lower end 33 side of the current plate 30. The upper end 42 (front end) of the oil receiver 40 is located closer to the front than the lower end 33 of the current plate 30. The oil pan 40 has a lateral width larger than the lateral width of the current plate 30, so that even if the oil attached to the current plate 30 drips from the lower end 33, the oil can be received and collected. A suction port 50d is formed between the upper end 42 (front side end) of the oil receiver 40 and the rectifying plate 30, and the suction port 50d communicates with the suction port 50c between the lower end 33 of the rectifying plate 30 and the inclined surface portion 21. I do. The oil pan 40 has, as a bottom surface 41, a surface that mainly comes into contact with rising oil smoke among the surfaces forming the oil pan 40.

  Referring to FIG. 5, when range hood 100 is installed, inclined surface portion 21, current plate 30, eaves portion 22, bottom surface portion 27, which is inclined upward from the back side toward the front side, and oil receiving portion The relationship between the inclination angles of the bottom surface 41 of the base 40 will be described. Here, as shown in FIG. 3B, the angle formed by the inclined surface portion 21 with the horizontal plane is an angle θ1, the angle formed by the straightening plate 30 with the horizontal plane is an angle θ2, the angle formed by the eaves portion 22 on the horizontal plane is an angle θ3, and the bottom surface is The angle formed by the portion 27 with the horizontal plane is defined as an angle θ4, and the angle formed by the bottom surface 41 of the oil pan 40 with the horizontal plane is defined as an angle θ5.

In the range hood 100, the angle θ1 formed by the inclined surface 21 with the horizontal plane, the angle θ2 formed by the straightening plate 30 with the horizontal plane, and the angle θ3 formed by the eaves section 22 with the horizontal plane have a relationship represented by the formula (1).
0 <θ3 <θ2 <θ1 Expression (1)

That is,
The angle θ2 that the current plate 30 forms with the horizontal plane <the angle θ1 that the inclined surface portion 21 forms with the horizontal plane
The current plate 30 is attached at a different inclination angle from the inclined surface 21 so that the distance between the upper end 32 and the inclined surface 21 is larger than the distance between the lower end 33 and the inclined surface 21. Thereby, the air suction amount of the upper suction port 50b of the current plate 30 is larger than that of the lower suction port 50c, and the air suction amount of the left and right side suction ports 50a of the current plate 30 is , From the lower end 33 to the upper end 32. Then, in accordance with the behavior of oil smoke and the like that tends to spread widely as it soars upward, the amount of suction increases from the lower side to the upper side inlet, so it is possible to reduce leakage of the hood part in the left and right direction Becomes

In the range hood 100,
Angle θ3 formed by eaves section 22 with the horizontal plane <angle θ2 formed by straightening plate 30 with the horizontal plane
The eaves portion 22 is bent at the upper end 25 of the inclined surface portion 21 so as to form a gentler inclination (inclination closer to the horizontal plane) than the inclination of the inclined surface portion 21, and the plane is formed to extend. If the angle θ3 formed by the eaves 22 with the horizontal plane is equal to or larger than the angle θ2 formed by the current plate 30 with the horizontal plane, the upper end 32 of the current plate 30 cannot form the eaves 22 and the suction port 50b. It cannot be collected efficiently.

In the range hood 100,
0 <the angle θ3 formed by the eaves portion 22 with the horizontal plane
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 suction force works effectively on the oil smoke and the like that leaks to the upper side of the range hood 100, and the oil smoke can be collected efficiently. Becomes That is, since the eaves 22 extend upward and incline, the suction force from the suction port 50 b formed by the gap between the rectifying plate 30 and the hood 20 reduces the eaves 22 to a horizontal position. It becomes easier to transmit to the upper region than in the case, and it becomes possible to efficiently collect the oil smoke that is going to leak upward. In addition, since the eaves portion 22 extends obliquely upward, it hardly gives the cook a sense of oppression.

In the case where the range hood 100 includes the bottom surface portion 27, the angle θ4 formed by the bottom surface portion 27 with the horizontal plane and the angle θ1 formed by the inclined surface portion 21 with the horizontal plane may have a relationship represented by the following expression (2).
0 <θ4 <θ1 Expression (2)

  According to this, since the bottom portion 27 is inclined upward toward the near side, when oil smoke (for example, grill exhaust) generated from the back side of the cooker comes into contact with the bottom portion 27, the inclined surface portion 21 is inclined. , And the leakage of oil smoke from the left and right of the bottom surface portion 27 to the outside of the range hood can be reduced. Also, the bottom portion 27 is bent at the lower end 26 of the inclined surface portion 21 so as to form a gentler inclination than the inclination of the inclined surface portion 21, and the flat surface is formed so as to extend, so that the rear side (the rear side) of the range hood 100 is formed. (/ Wall side) and the space between the cooker can be widely secured, and a convenient situation can be secured without giving the user a feeling of oppression.

Further, in the case where the range hood 100 includes the oil receiver 40, the angle θ5 that the bottom surface 41 of the oil receiver 40 forms with the horizontal plane and the angle θ2 that the rectifying plate 30 forms with the horizontal plane may have the relationship of the formula (3). Good.
0 <θ5 ≦ θ2 Expression (3)

  According to this, the bottom surface 41 of the oil receiver 40 is inclined upward toward the near side, and the upper end 42 of the oil receiver 40 forms the suction port 50 d with the rectifying plate 30, so that the bottom surface of the oil receiver 40 is formed. Oil smoke or the like that has come into contact with 41 is smoothly guided upward along the bottom surface 41 of the inclined oil pan 40, and is efficiently sucked into the suction port 50d. In addition, since the angle θ5 of the bottom surface 41 of the oil receiver 40 is equal to or less than the angle θ2 of the rectifying plate 30, a step between the lower end of the bottom surface 41 of the oil receiver 40 and the inclined surface portion 21 can be reduced, and Since the oil smoke that has risen along is less likely to be blocked (collides with the step), it is possible to reduce the possibility that the oil smoke is blocked (collides with the step) and diffuses in the left-right direction.

With reference to FIG. 6, a modified example of the present embodiment will be described. In order to avoid redundant description, the same components are denoted by the same reference numerals, description thereof will be omitted, and different points will be mainly described. The different components are the eaves 22A and the bottom 27A. The hood portion 20A is a rectangular flat plate-shaped inclined surface portion 21, an eaves portion 22A that extends from the upper end 25 of the inclined surface portion 21 toward the near side (front side) and extends from the lower end 26 of the inclined surface portion 21 to the wall side. It has a bottom surface 27A that extends in a curved manner.

  The angle formed by the tangent of the eaves 22A at the upper end 25 of the inclined surface 21 to the horizontal plane is the same as the angle θ1 formed by the inclined surface 21 to the horizontal plane. From there, the eave portion 22A is curved with a large curvature toward the upper end 32 of the current plate 30 and forms a suction port with the upper end 32 of the current plate 30. In this modification, the angle θ3 formed by the eaves portion 22A with the horizontal plane is, as shown in FIG. 3B, the upper end 25 of the inclined surface portion 21 that is the root of the eaves portion 22A and the tip of the eaves portion 22A. An angle formed by a straight line connecting to a certain end 23A and a horizontal plane.

  The angle formed by the tangent of the bottom surface 27A at the lower end 26 of the inclined surface 21 to the horizontal plane is the same as the angle θ1 formed by the inclined surface 21 to the horizontal plane. From there, the bottom surface portion 27A curves with a large curvature toward the wall and comes into contact with the wall surface. The angle θ4 formed by the bottom surface 27A and the horizontal plane is defined by a straight line connecting the lower end 26 of the inclined surface 21 which is the root of the bottom surface 27A and the tip of the bottom surface 27A, as shown in FIG. It is the angle made with the horizontal plane.

  Also in the present modification, the angle formed by the inclined surface portion 21 with the horizontal plane is the angle θ1, the angle formed by the straightening plate 30 with the horizontal plane is the angle θ2, the angle formed by the eaves portion 22A on the horizontal plane is the angle θ3, and the angle formed by the bottom surface portion 27A is the horizontal plane. Is the angle θ4 and the angle between the bottom surface 41 of the oil receiver 40 and the horizontal plane is the angle θ5, and the above-described relationships of the expressions (1), (2), and (3) are established. With this configuration, the current plate 30 is attached at an inclination angle different from that of the inclined surface portion 21, so that the upper suction port is larger than the lower suction port and the suction flow rate is larger, and the eaves portion 22 </ b> A Since the suction port is formed so as to surround the upper end 32, a suction hood effectively acts on oil smoke or the like leaking to the upper side of the range hood, and the range hood can efficiently collect oil smoke. Can be provided.

  It should be noted that the present invention is not limited to the illustrated embodiment, and can be implemented with a configuration that does not deviate from the contents described in the claims. That is, the present invention has been particularly shown and described with particular reference to particular embodiments thereof, but without departing from the spirit and purpose of the invention, Those skilled in the art can make various modifications in application examples and other detailed configurations.
