range hood

The present invention relates to a range hood.

Conventionally, a range hood provided with a hood part which inclines upwardly from the depth side of an installed range hood toward the front side, and collects smoke etc. rising from the cooker below is known (for example, patent document) range hood indicated by 1). In such a range hood, by providing left and right side plates on the side of the hood and front plates on the front of the hood, a recess is formed around the rectifier plate, and in order to efficiently collect smoke, etc., it is configured to receive rising smoke. are doing

Japanese Patent Laid-Open No. 2003-097838

However, in such a configuration, if the left and right side plates are present, visibility from the left and right is poor, and the left and right side plates and the front plate are present so as to protrude toward the cook side, thereby imparting a sense of pressure to the cook. Furthermore, since the recessed part is formed in the periphery of a baffle plate, there were many unevenness|corrugations and the cleanability was bad. Therefore, it is conceivable to remove the concave portion around the baffle plate, but if the concave portion is simply removed around the baffle plate, the above-mentioned rising smoke etc. cannot be received, and all rising smoke etc. are not collected. As a result, there was a problem of leakage to the outside of the range hood.

Accordingly, the present invention provides a range hood capable of efficiently trapping rising smoke and the like while eliminating pressure on cooks such as left and right side plates and forming recesses around the rectifying plate.

In order to solve the above problems, a range hood is installed above the cooker and collects smoke generated by cooking, the main body having a blower therein, and when installed, to face upward from the depth side toward the front side. The inclined surface portion of the rectangular flat plate and the awning portion extending forward from the upper end of the inclined surface portion are larger than the opening communicating with the hood portion for collecting smoke and the blower provided on the inclined surface portion, and between the hood portion and the edge portion A rectangular rectifying plate that forms an intake port for the flow of air generated by the blower in A range hood is provided in which the angle θ1 formed with the horizontal plane, the angle θ2 formed by the baffle plate with the horizontal plane, and the angle θ3 formed by the awning portion with the horizontal plane have a relationship of Equation (1).

0<θ3<θ2<θ1 … (1) Formula

According to this, since the baffle plate is mounted at an inclination angle different from that of the inclined surface portion, the upper intake port is larger than the lower intake port, and the intake flow rate is large. It is possible to provide a range hood in which a suction force effectively acts on the smoke, etc., which is about to leak to the side, and it is possible to efficiently collect the smoke. That is, when the awning portion is inclined upwardly, the suction force from the suction port composed of the gap between the rectifying plate and the hood portion is more likely to be transmitted to the upper region than when the awning portion is horizontal, preventing smoke from leaking upward. It becomes possible to collect efficiently.

In addition, the baffle plate is in front of the inclined surface portion, and the upper end side is mounted at a different inclination angle from the inclined surface portion so that the distance from the inclined surface portion is greater than the lower end side. It becomes possible to reduce the leakage to the left-right direction of the hood because it becomes possible to inhale strongly as it goes upward.

In addition, since there are no side plates or the like on the left and right side surfaces of the hood so that the baffle plate can be visually recognized from the side, and the awning portion extends obliquely upward, it does not give pressure to the cook, and is concave around the baffle plate. It is possible to provide a range hood with high cleaning properties because there are no burrs and there are few irregularities.

Further, the hood portion may further have a bottom surface portion extending from the lower end of the inclined surface portion, and the angle θ4 between the bottom surface portion and the horizontal plane may be characterized in that it has a relationship of Expression (2).

0<θ4<θ1 … (2) Formula

According to this, when the bottom surface part is inclined upward toward the front side, smoke (for example, grill exhaust) generated from the depth side of the cooker is smoothly guided to the inclined surface part when it comes into contact with the bottom surface part, It is possible to reduce the leakage of smoke from the left and right sides of the bottom surface to the outside of the range hood.

In addition, it has a left and right width greater than the left and right width of the baffle plate, further comprising an oil receiving part detachably provided in the hood at the lower end of the baffle plate, and forming a suction port between the front end of the oil accommodating part and the rectifying plate Then, the angle θ5 between the bottom surface of the oil container and the horizontal plane may be characterized in that it has a relationship of equation (3).

0<θ5≤θ2 … (3) Formula

According to this, the bottom surface of the oil accommodating part is inclined upward toward the front side, and the upper end of the oil accommodating part forms a suction port between the baffle plates, so that smoke or the like contacting the bottom surface of the oil accommodating part is discharged from the inclined oil accommodating part. It is smoothly guided upward along the floor and is efficiently sucked into the suction port.

As described above, according to the present invention, there is provided a range hood that efficiently collects rising smoke, etc. while eliminating the pressure applied to the cook such as the left and right side plates and the formation of a recess around the rectifying plate. can do.

<First embodiment>

The range hood 100 according to the present embodiment will be described with reference to FIGS. 1 to 5 . The range hood 100 is installed above a cooker (not shown), collects smoke or vapor rising generated by cooking, and exhausts it to the outdoors through a duct (not shown). The range hood 100 includes a main body 10 connected to a duct, a hood portion 20 for collecting smoke, and the like, and a rectifying plate forming a suction port 50 for sucking air between the hood portion 20 . (30) is provided.

The main body 10 has inside the blower 11 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 a cooker, while being connected in the duct and upper surface provided in the installation place, it is connected with the duct cover D which covers a duct. Since the main body 10 is formed so that an upper surface and a back surface may be substantially flat, an upper surface may be parallel to a ceiling, and a back surface may be parallel (or in contact with) a wall, they intersect each other at right angles. The main body 10 is formed so as to be inclined upward from the depth side (back side/wall side) to the front side (front side) when installed, in the main part of the front side. Accordingly, the approximate external shape of the main body 10 when viewed from the side is a right-angled triangle, and the hypotenuse portion of the triangle is opened, and the hood portion 20 is provided so as to cover the opening.

The hood part 20 consists of an inclined surface part 21 which is a rectangular flat plate, and the awning part 22 which bends and extends from the upper end 25 of the inclined surface part 21 to the front side (front side). The opening serving as the main part on the front side of the main body 10 is covered with the inclined surface part 21 of the rectangular flat plate, and as described above, when installed, it is formed so as to be inclined upward from the depth side toward the front side. Therefore, the inclined surface portion 21 constitutes a plane inclined upward from the depth side toward the front side when installed. As shown in FIG. 3 and FIG. 4, the inclined surface part 21 has the opening part 24 at the center upper part, and forms the flow path of the air flow which the blower 11 generated. In addition, it is preferable that a filter for trapping oil is provided in the opening 24 . In this way, the inclined surface portion 21 is composed of only a substantially flat surface except for the opening 24 and the clamps for holding the baffle plate 30, and is easy to clean even if oil adheres. . In addition, in the present embodiment, the switch 1 for adjusting the on/off of the blower 11 and the amount of air is provided on the inclined surface portion 21 .

The awning part 22 consists of a plane which bends and extends from the upper end 25 of the inclined surface part 21 to the front side. The awning part 22 is bent to the upper end 25 of the inclined surface part 21 so that the inclination (closer inclination to a horizontal plane) may be made|formed rather than the inclination of the inclined surface part 21, and the plane is extended and formed. The awning part 22 is formed so that the front-back direction (the direction from the depth side to the front side) may become substantially equal across the whole left-right direction, and the awning part 22 itself forms a long thin rectangle. Moreover, since the awning part 22 consists of the same left-right width as the inclined surface part 21, it is making it easy to transmit the suction force from a suction port to the area|region above over the whole left-right direction of the hood part 20. As shown in FIG.

Further, the hood portion 20 may further have 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 have a gentler inclination than the inclination of the inclined surface portion 21, and is formed to extend in a plane. The bottom surface portion 27 is formed so that the front-back direction (the direction from the depth side to the front side) is approximately equal across the entire left-right direction, and preferably abuts against the wall when installed, and is in contact with the wall among the ends of the bottom surface portion 27 Particular preference is given to face-to-face contact. That is, it is preferable that the end of the bottom surface portion 27 is in a state where there is no step difference with the rear surface of the main body 10 on the rear surface side. If the bottom surface portion 27 is provided, smoke generated from the depth side of the cooker (eg, exhaust from the grill of the cooker) can also be guided upward (front side) of the hood portion. The bottom surface portion 27 has the same left and right width as the inclined surface portion 21, so that the bottom surface portion is horizontally provided over the entire left and right direction of the hood portion 20, thereby inducing smoke upward (front side) of the hood portion. can Further, in the present embodiment, an infrared light receiving unit 3 for accommodating the illumination 2 and remote control operation is provided on the bottom surface portion 27 .

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 smoke, etc. As described above, the inclined surface portion 21 of the hood portion 20, the awning portion 22 , each of the bottom surface portion 27 is generally composed of only a flat surface, and does not include a member such as a side plate. Therefore, in the range hood 100, the side surface of the hood portion 20 is open, and when viewed from the side, both the right side from the left side and the left side from the right side can be seen. has been Of course, the rectifier plate 30 mounted on the front side of the hood unit 20 can also be visually recognized. In this way, it is possible to eliminate a feeling of pressure on cooks such as the left and right side plates and the formation of recesses around the rectifying plate. That is, there are no side plates on the left and right sides of the hood part 20 so that the rectifier plate 30 can be visually recognized from the side, no pressure is given to the cook, and a recessed portion around the rectifier plate 30 is not provided. It is possible to provide the range hood 100 with high cleaning properties in that there are no irregularities and there are few irregularities.

The baffle plate 30 is a rectangular flat plate larger than the opening 24 communicating with the blower 11 provided in the inclined surface portion 21, and is a front surface (front side) of the inclined surface portion 21. When viewed from the front, the opening ( 24) is provided. The baffle plate 30 is mounted through a chuck provided on the inclined surface portion 21 . The edge portion 31 of the flat plate, which is the rectifying plate 30 , forms a suction port 50 for sucking air between the hood portion 20 and the front surface of the plate.

More specifically, in the baffle plate 30 , the side end 34 , which is the edge part 31 located on the left and right, forms a suction port 50a between the sloping surface part 21 and the baffle plate 30 . The upper end 32 (the front end), which is the edge portion 31 positioned above, forms a suction port 50b between the inclined surface portion 21 and the awning portion 22, and in the rectifying plate 30, The lower end 33 , which is the edge portion 31 positioned below, forms a suction port 50c between the inclined surface portion 21 and the lower end portion 31 . Since the upper end 32 and lower end 33 are provided in parallel with the inclined surface portion 21 as for the cross-section in the direction perpendicular to the air inflow direction at the inlet 50b and the inlet 50c, It is rectangular. Further, 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 area of the suction port 50b is larger than the area of the suction port 50c. Therefore, the intake amount of air of the intake port 50b is larger than that of the intake port 50c.

Since the distance between the upper end 32 and the inclined surface portion 21 is provided farther than the distance between the lower end 33 and the inclined surface portion 21, the cross section in the direction perpendicular to the inflow direction of the air in the suction port 50a is, It is not rectangular, but forms an approximately triangular shape that is small on the lower end 33 side and becomes larger on the upper end 32 side. Then, the intake amount of air in the intake port 50a is not uniform in the vertical direction, and changes gradually so as to increase from the lower end 33 to the upper end 32 .

In addition, although the distance between the upper end 32 and the inclined surface portion 21 of the baffle plate 30 is provided farther than the distance between the lower end 33 and the inclined surface portion 21 , the upper end that is the front end of the baffle plate 30 . (32) is located in the depth side (back side) rather than the edge part 23 of the awning part 22 (front-side edge part of the awning part 22). That is, the edge part 23 of the awning part 22 is located in front of the upper end 32 used as the front edge part of the baffle plate 30. As shown in FIG. Thereby, it is possible to prevent the spread of smoke that is going to rise from the upper end 32 of the baffle plate 30 in the awning portion 22 .

In addition, the range hood 100 may further provide the hood part 20 and the oil accommodating part 40 detachably on the lower end 33 side of the baffle plate 30 . The upper end 42 (front end) of the oil accommodating part 40 is located in front of the lower end 33 of the baffle plate 30 . The oil accommodating part 40 has a left and right width greater than the left and right width of the baffle plate 30, so that even if the oil attached to the baffle plate 30 flows down from the lower end 33, it can receive and recover the oil. have. A suction port 50d is formed between the upper end 42 (front end) of the oil accommodating part 40 and the baffle plate 30 , and the suction port 50d is formed with the lower end 33 of the baffle plate 30 and the inclined surface. It communicates with the suction port 50c between the parts 21. The oil accommodating part 40 is provided with the surface which the rising smoke mainly contacts as the bottom surface 41 among the surfaces which form the oil containing part 40. As shown in FIG.

Referring to FIG. 5 , when the range hood 100 is installed, the inclined surface portion 21, the rectifying plate 30, the awning portion 22, and the bottom surface portion that are inclined upward from the depth side toward the front side ( 27), and the relationship between the inclination angle of the bottom surface 41 of the oil accommodating part 40 is demonstrated. Here, as shown in this figure (B), the angle θ1 the inclined surface portion 21 makes with the horizontal plane, the angle θ2 the rectifier plate 30 makes with the horizontal plane, the awning portion 22 is formed with the horizontal plane Let the angle be the angle θ3, the angle the bottom surface part 27 makes with the horizontal plane is the angle θ4, and the angle the bottom surface 41 of the oil accommodating part 40 makes with the horizontal plane is the angle θ5.

In the range hood 100 , the angle θ1 between the inclined surface portion 21 and the horizontal plane, the angle θ2 between the baffle plate 30 and the horizontal plane, and the angle θ3 between the awning portion 22 and the horizontal plane are (1) has a relationship of

0<θ3<θ2<θ1 … (1) Formula

in other words,

The angle θ2 the baffle plate 30 makes with the horizontal plane has a relationship of <the angle θ1 the sloping surface part 21 makes with the horizontal plane, and the baffle plate 30 has a 33) and the inclined surface portion 21 so as to be farther than the distance, the inclined surface portion 21 is mounted at a different inclination angle. As a result, the intake amount of air at the intake port 50b on the upper side of the baffle plate 30 increases compared to the intake port 50c on the lower side, and the intake amount of air at the intake ports 50a on the left and right sides of the baffle plate 30 is, It changes to increase as it goes from the lower end 33 to the upper end 32. In this way, in accordance with the movement of smoke or the like to spread widely as it rises upward, the suction amount increases as the suction port goes from the lower side to the upper side, so that it is possible to reduce leakage in the left and right directions of the hood.

In addition, in the range hood 100,

2 이상인 경우, 정류판(30)의 상단(32)은, 차양부(22)와 흡입구(50b)를 형성할 수 없기 때문에, 연기를 효율적으로 포집할 수 없다.There is a relationship between the angle θ3 formed by the awning portion 22 with the horizontal plane and the angle θ2 formed by the rectifier plate 30 with the horizontal plane, and the awning portion 22 has a gentler inclination than the inclination of the inclined surface portion 21 (than the horizontal plane). It is bent to the upper end 25 of the inclined surface portion 21 to achieve a close inclination), and the plane is formed to extend. If, the angle formed by the awning portion 22 and the horizontal plane

3 The angle between the rectifying plate 30 and the horizontal plane

In the case of two or more, since the upper end 32 of the baffle plate 30 cannot form the awning part 22 and the suction port 50b, it cannot collect smoke efficiently.

In addition, in the range hood 100,

There is a relationship of 0<the angle θ3 that the awning part 22 makes with the horizontal plane, and the awning part 22 inclines upward so that it may go upward from the depth side toward the front side. As described above, by having a relationship of 0 < angle θ3 < angle θ2 , a suction force effectively acts on the smoke that is about to leak toward the upper side of the range hood 100 , and it is possible to efficiently collect the smoke. That is, when the awning part 22 is inclined upwardly extending, the suction force from the suction port 50b composed of the gap between the rectifying plate 30 and the hood part 20 is the shading part 22 is horizontal. It becomes easier to transmit to an upper area|region, and it becomes possible to collect efficiently the smoke which is going to leak upwards. Moreover, since the awning part 22 inclines upward and extends, there are few cases where a pressure feeling is provided to a cook.

In addition, in the range hood 100, when the bottom surface portion 27 is provided, the angle θ4 between the bottom surface portion 27 and the horizontal plane and the angle θ1 between the inclined surface portion 21 and the horizontal surface are of the formula (2). You can have a relationship.

0<θ4<θ1 … (2) Formula

According to this, if the bottom surface portion 27 is inclined upward toward the front side, when smoke (eg, grill exhaust) generated from the depth side of the cooker comes into contact with the bottom surface portion 27, the inclined surface portion 21 By smoothly guiding, it is possible to reduce the leakage of smoke from the left and right sides of the bottom surface portion 27 to the outside of the range hood. In addition, the bottom surface portion 27 is bent toward the lower end 26 of the inclined surface portion 21 so as to have a gentler inclination than the inclination of the inclined surface portion 21 , and the plane is formed to extend, so that the depth side of the range hood 100 . It is possible to secure a wide space between the (back side/wall side) and the cooker, so that it is possible to secure a convenient situation without giving pressure to the user.

In addition, in the range hood 100 , when the oil accommodating part 40 is provided, the angle θ5 between the bottom surface 41 of the oil accommodating part 40 and the horizontal plane and the angle θ5 between the rectifying plate 30 and the horizontal plane θ2 may have a relationship of the expression (3).

0<θ5≤θ2 … (3) Formula

According to this, the bottom surface 41 of the oil accommodating part 40 is inclined upward toward the front side, and the upper end 42 of the oil accommodating part 40 is positioned between the rectifying plate 30 and the suction port 50d. By forming , smoke or the like that has come into contact with the bottom surface 41 of the oil accommodating part 40 is smoothly guided upward along the bottom surface 41 of the inclined oil accommodating part 40, and to the suction port 50d. is absorbed efficiently. In addition, if the angle θ5 of the bottom surface 41 of the oil storage unit 40 is equal to or less than the angle θ2 of the rectifying plate 30 , the step difference between the lower end of the bottom surface 41 of the oil storage unit 40 and the inclined surface portion 21 . It is possible to reduce , and since the case in which smoke rising along the hood is blocked (impacts with a step) is reduced, it is possible to reduce diffusion in the left and right direction by being blocked (colliding with a step).
