Description

  The present invention relates to a flow of polluted air such as waste gas, oil smoke, hot smoke (steam from a pan, etc.) generated during cooking by a cooking device such as a gas stove, electric stove, or electromagnetic induction heating type cooking heater (so-called IH cooking heater). In order to improve the suction and capture efficiency, the present invention relates to a current plate provided in a capture space that opens downward in the hood portion, and a range hood provided with the current plate.

In recent years, thin (flat) range hoods are attracting attention in consideration of a unified design that matches system kitchens. This thin range hood has an exhaust device on the hood part that has a capture space that opens downward, and an exhaust device that propagates the suction force to the capture space and exhausts the contaminated air that has been sucked and captured into the capture space. (For example, see Patent Documents 1 to 3).
In other words, the thin range hood is widely used as a hood part without being restricted by the design with a sense of unity with the system kitchen such as matching the kitchen shelves attached and arranged on one side or both sides of the hood part. It attracts attention because it can implement innovative designs.

And in thin range hoods, as shown in FIG. 1 of each of Patent Documents 1 to 3, the trapping space that opens downward in the hood part has a trapping efficiency (collection efficiency) for sucking and trapping contaminated air. A rectifying plate is provided to increase the height.
In this way, by providing the current plate in the capture space of the hood portion, a suction gap that increases the flow velocity of contaminated air between the peripheral edge of the current plate and the peripheral edge of the opening of the capture space (in Japanese Patent Application Laid-Open No. 2003-133867, suction). Space, which is referred to as an intake port in Patent Document 2), thereby improving the intake and capture efficiency of contaminated air while being a shallow capture space.
In other words, the depth of the capture space becomes shallower as the hood becomes thinner, and as a result, contaminated air that tends to spread as it rises from the hot mouth (crater) of a heating cooker such as a gas stove or cooking pan rises. It cannot be captured (collected) in the space, and it is lost to the kitchen ceiling.
In order to suppress this escape and increase the capture efficiency in the capture space, by installing a baffle plate, secure a suction gap that increases the momentum of the suction flow velocity between the opening peripheral edge of the capture space and spreads as it rises Improvements have been made to ensure that the trapping space is sucked and captured by the suction flow velocity that acts vigorously on the suction gap without escaping the contaminated air.

Moreover, in the thin range hood, it is shown by patent document 1-patent document 3. For example, as shown in Patent Document 1, the attachment to the kitchen wall is performed by screwing the exhaust box of the exhaust device (blower unit) with an L-shaped hanging bracket or the like. For this purpose, the exhaust device (exhaust box) is positioned on the rear side of the hood portion so as to be substantially flush with the rear surface portion that is the wall contact surface portion of the hood portion, and the top plate of the hood portion (or the top of the capture space). It is communicated with an intake port (opening 21a of Patent Document 1) that is opened in the surface portion and is installed on the hood portion. In other words, in the thin range hood, the exhaust device is fixedly fixed to the kitchen wall by screwing using a hanging metal fitting, etc., and the hood portion is supported on the exhaust device and is positioned almost directly above the cooking device. The
And, as shown in Patent Document 1 and Patent Document 2, the top plate of the hood portion is hidden so that the exhaust device is located on the rear side of the hood portion as described above. A curtain board (decorative board) attached from the top to the kitchen ceiling can be made substantially flush with the door surface of a kitchen shelf or the like.

  In addition, in the thin range hood, as shown in Patent Document 3, the lighting that illuminates the hand of the cooker, the hot mouth of the cooking device, the bottom of the cooking pan, etc. In preparation for the front edge of the opening along the front portion of the hood portion located on the side (cooker side), the cooker's hand and pan bottom can be illuminated effectively.

Japanese Patent Laying-Open No. 2006-170539 (see paragraph numbers 0011 to 0012 and FIG. 1) JP 2007-107751 (see paragraph numbers 0054 to 0055 and FIG. 1) JP 2007-78223 A (see paragraph number 0033 and FIG. 1)

By the way, as shown by patent document 3, it is effective in illuminating the hand of a cook, the pan bottom of a cooking pan, etc. by providing illumination in the front part side of a food | hood part. In other words, a cooking device such as a gas stove is equipped with two hot spots (such as a crater) at the front side of the top plate, which has a substantially rectangular shape in plan view, and at the center of the rear side. The hot mouth is frequently used.
For that purpose, when cooking dishes such as stir-fried vegetables in a Chinese wok or beef stew in a deep-bottom pan using the two hot-mouths on the front side, the bottom of the pan, especially the deep-bottom pan on the hot-mouth in the two front sides. It is effective to provide illumination by being positioned on the front side of the hood portion, which is positioned almost directly above the two hot ports on the front side, which can be surely illuminated to the bottom of the pan.

However, in the prior art, as shown in FIG. 1 of Patent Document 3, the edge of the front edge of the opening of the capture space along the front surface is provided in order to provide the illumination on the front surface side of the hood. The width is widened from the front surface portion of the hood portion toward the inside of the capture space over the entire length in the edge direction (the entire lateral width of the hood portion). In other words, conventionally, in order to secure a lighting installation part for incorporating a lighting box to which lighting such as a lamp is installed in a downward opening state, the edge width of the front edge of the opening is adjusted to match the lighting installation part. Wide in the entire direction.
For this reason, the space opening in the capture space, which is located just above the two hot ports at the front side, where the usage frequency is high and the rate of occurrence of polluted air (swelling rate) is high, is defined by the wide opening front edge. As a result, it became a cause of causing problems such as a part of the contaminated air rising from the hot mouths and cooking pots at the two front sides to the kitchen ceiling. In other words, part of the contaminated air that rises into the capture space hits the front edge of the wide opening, diffuses and escapes from the suction gap to the kitchen ceiling, etc. without being captured by the capture space. The problem (problem) which remains is still left, and the solution is desired.

Therefore, the present invention was devised to solve the above-described problems, and is a thin range hood that effectively illuminates the bottom of a cooking pot that has been applied to two hot mouths on the front side of the heating cooker. Rectifying plate provided in a capture space with an opening shape that can reliably suck and capture the contaminated air rising from the hot mouth and cooking pan at the two locations on the front side of the hood that can perform And a range hood provided with the current plate.
In addition, the suction gap along the opening front edge part and the opening both edge parts of the remaining three edges, excluding, for example, one edge side of the opening rear edge part of the capture space located on the kitchen wall side. Another object is to provide a range hood equipped with a rectifying plate that can be effectively propagated and can be expected to further improve the trapping efficiency of polluted air that rises from two hot ports and cooking pans on the front side.

In order to solve the above-mentioned problem, in the current plate of the present invention, at least a part of the opening peripheral edge of the capture space of the hood portion is bulged so as not to extend over the entire length in the edge direction toward the inside of the capture space. A rectifying plate that is provided with a bulging portion, is attached to the capture space having an expansion space provided on both sides or one side of the bulging portion, and secures a suction gap between the opening peripheral portion, The rectifying plate body includes a dent that does not extend over the entire length of the rectifying plate facing the bulging portion, and the dent has a bottom view shape that secures the suction gap between the bulging portion and the bulging portion. In the portion having the expansion space formed on the peripheral edge portion of the rectifying plate body and provided on both sides or one side of the bulging portion, the suction gap is wider than the other portion .

  Here, the hollow portion has a one-side edge portion along a bulging shape of the bulging portion among the four peripheral edge portions of the rectifying plate main body that has a substantially square shape in a bottom view, and the capture It is preferable to adopt a configuration formed by extending the space toward the expansion space.

According to the rectifying plate having such a configuration, an opening-shaped capture space having a bulging portion at least at a part of the opening peripheral edge of the capturing space and having an expansion space of the capturing space on both sides or one side of the bulging portion. By attaching the current plate main body, a suction gap can be secured between the bulging portion and a suction gap can be secured between the opening peripheral edge portion in the expansion space.
For example, a bulging part used as a lighting installation part is provided at the central part in the edge direction of the opening front edge part which is a part of the opening peripheral part of the capture space along the front part of the hood part located on the kitchen side. In the shape of the opening of the capture space, the suction gap is secured between the bulge and the bulge, and the gap between the bulge and the front edge of the opening in the expansion space on both sides of the bulge A current plate main body can be attached to the capture space so as to ensure a gap.
Thereby, for example, the use frequency is high, and the polluted air that rises from two hot mouths and cooking pans on the front side of the cooking device located on the kitchen side is secured between the bulging peripheral surface of the bulging portion. Suction without failing to escape to the kitchen ceiling due to the suction action generated in the suction gap that is secured between the suction gap and the expansion spaces on both sides that are located just above the front two hot ports. Expected to capture.

Further, in the range hood of the present invention, a hood portion having a capture space, an exhaust device installed on the hood portion in communication with an intake opening opened in a top surface portion of the capture space, and the capture space is attached positioned on, the suction and rectifying plate to secure the gap, a range hood that is provided with a least a portion of the opening edge of the capturing space between the opening peripheral edge portion of said capturing space, A bulging portion that bulges toward the inside of the capture space so as not to extend over the entire length in the edge direction, and includes an expansion space of the capture space on both sides or one side of the bulge portion, and the bulge The rectifying plate main body in a bottom view shape that secures the suction gap between the portion includes a hollow portion that does not extend over the entire length of the rectifying plate facing according to the bulging portion at the peripheral edge of the rectifying plate, Expansion provided on both sides or one side of the bulge In the portion having between the width of the suction gap is equal to or wider than other portions.

  Here, the bulging portion is formed by narrowing an edge width of the opening peripheral portion except for a part of the opening peripheral portion of the capture space that has a substantially square shape in a bottom view. The dent is formed in the part of the rectifying plate and is formed in a size that is sufficient to secure the suction gap between the opening and the peripheral edge of the opening, and has a substantially rectangular shape in bottom view. Among the portions, the one edge portion is formed along the bulging shape of the bulging portion and extended toward the expansion space side of the capture space to form the one edge portion. It is suitable to adopt.

In addition, the intake port is opened at a position closer to the wall contact surface portion side of the hood portion that is in contact with the kitchen wall than the central portion of the hood portion in a bottom view, and the suction gap is formed on the wall contact surface portion side. It is preferable that the gap is narrow between the opening peripheral edge located at the center and the other opening peripheral edge other than the wall contact portion side.
Further, the bulging portion is formed integrally with an oil panel provided in the hood portion, and from the periphery of the bulging surface that is substantially planarly connected to the peripheral edge of the opening, the space bottom of the capture space and the expansion space It is preferable that the bulging peripheral surface shape reaching the bottom of the space is streamlined, and this bulging part is a lighting installation part, and the lighting installation part is a hood part located on the kitchen side. It is provided in the center part of the edge direction of the said opening peripheral part along a front part. In other words, the lighting installation portion is provided at the opening peripheral edge located substantially directly above the central portion between the two hot ports on the front side of the heating cooker, and two hot ports on the side are provided on both sides of the lighting installation portion. An expansion space of the capture space located substantially directly above is provided.

According to such a configuration, the bulging peripheral surface of the lighting installation portion and the rectifying plate which are bulging portions that bulge inside the capture space by the suction force transmitted from the vent to the capture space by the operation of the exhaust device The suction action is effectively generated in the suction gap that is secured between the hollow portion of the capture space and between the opening peripheral edge portion of the expansion space of the capture space and the peripheral edge portion of the rectifying plate.
As a result, the contaminated air that rises from the two hot mouths and cooking pans on the front side of the heating cooker is sucked and captured from the suction gap between the bulging peripheral surface of the lighting installation section, and the two front side abbreviations. The expansion space can be sucked and captured from the gap between the opening peripheral edge portions of the expansion space on both sides located directly above.

In addition, the suction gap is narrow between the hood part in contact with the kitchen wall and the opening peripheral part located on the wall contact surface part side, and a wide suction gap is secured between the opening peripheral part other than the wall contact part side. Is done. For example, the suction gap on the rear side of the hood part in contact with the kitchen wall is narrow, and the suction gaps on the kitchen side and the front and left and right sides of the hood part on the kitchen shelf side are wide.
As a result, the suction force propagated from the intake port to the capture space is larger in the suction gaps on the front side and the left and right sides of the wide hood part than in the suction gap side on the rear side of the hood part that is set narrowly. Propagated.
In other words, the narrow suction gap has a large airflow resistance (airflow friction), and the wide suction gap has a low airflow resistance. The front suction gap and the left and right suction gaps are increased, and the suction action generated vigorously in the front suction gap and the left and right suction gaps from the two hot mouths and cooking pans on the front side of the heating cooker. Without taking away the polluted air that spreads as it rises, it can be reliably sucked and captured into the capture space.

In addition, since the bulging part is integrally provided in the oil panel, for example, when the bulging part is used as a lighting installation part, the lighting installation part serves as a blindfold makeup part for hiding the lighting box. Thereby, illumination can be installed without requiring a separate blindfold member or the like.
In addition, by attaching the oil panel to the hood part, the lighting installation part can be provided at the center part in the edge direction of the opening peripheral part along the front part of the hood part, so that the cooker's hand and the hot mouth of the heating cooker The bottom of the cooking pot that is hung on the top of the hood can be illuminated uniformly by illumination provided on the front side of the hood.
In addition, the bulging surface shape of the bulging part is streamlined toward the bottom of the capture space and expansion space, so that the contaminated air can be captured in a smooth flow without receiving airflow resistance. And it is sucked and captured in the expansion space.

The current plate of the present invention is configured as described above, for example, the edge direction of the opening front edge that is a part of the opening peripheral edge of the capture space along the front surface of the hood located on the kitchen side In the opening shape of the capture space provided with a bulging part used as a lighting installation part at the central part of the A suction gap can be ensured between the two and the front opening edge in the expansion space on both sides continuous from the bulging base portion of the bulging portion.
As a result, the suction gap that is secured between the swollen peripheral surface of the bulging part and the front two places of the contaminated air that rises from the hot mouth and cooking pan at the front two places of the cooking device located on the kitchen side The suction action that is generated in the suction gap secured between the open spaces located on both sides of the opening and located almost directly above the hot mouth of the kitchen can surely suck and capture without being released to the kitchen ceiling.

In addition, the range hood of the present invention is configured as described above, so that in the expansion space on both sides of the capture space, which is positioned substantially directly above the two hot ports on the front side of the cooking device, the expansion space Contaminated air that flies from the two hot mouths and the cooking pan at the front side of the heating cooker due to the suction flow velocity generated in the suction gap secured between the peripheral edge of the opening and the peripheral edge of the current plate It is possible to catch and suck and capture without missing.
In other words, the expansion space on both sides is opened and positioned almost directly above the two heat ports on the front side, and more suction force is propagated from the air intake port to the peripheral edge (extension edge) of the current plate Since the suction flow velocity vigorously acts on the suction gap secured between the two, the air can be caught securely in the expansion space on both sides without letting out the contaminated air that has risen from the two hot ports and the cooking pan. Inhalation can be captured.

In addition, for example, the suction gap on the rear side of the hood that touches the kitchen wall is narrow, and the suction gap on the kitchen side and on the front and left and right sides of the hood on the kitchen shelf side is secured widely so that it can be captured from the intake port. The suction force of the exhaust system that is propagated to the space is more propagated to the suction gaps on the front side and the left and right sides of the hood part that are set wider than the suction gap side on the rear side of the hood part that is set narrower Can do.
As a result, the momentum of the suction flow velocity in the suction gaps on the front side and the left and right sides of the hood part can be further increased, so that the trapping efficiency of the contaminated air that rises from the hot mouths and cooking pans at the two front sides of the cooking device Can be expected to improve further.

  In addition, when the bulging portion is used as an illumination installation portion for attaching illumination, the illumination installation portion serves as a blindfold makeup portion for concealing the illumination box, so that the installation cost of illumination can be kept low.

  In addition, the bulging peripheral surface shape of the lighting installation part is streamlined toward the bottom of the capture space and the expansion space, so that the contaminated air is not subjected to airflow resistance and the capture space is smoothly flowed. And it is sucked and captured in the expansion space. As a result, it is possible to more reliably suck and capture the contaminated air flying from the hot mouths and cooking pots at the two front sides of the heating cooker to the kitchen ceiling side, and improve the capture efficiency.

It is often transmitted to the suction gaps S1 and S3.
That is, as shown in FIG. 2, the rear suction gap S2 is close to the intake port 12 through which the suction force is propagated, but compared to the interval L2 between the front suction gap S1 and the interval L3 between the left and right suction gaps S3. Since the interval L1 is set narrow, the airflow resistance (airflow friction) increases. On the other hand, since the gaps L1 and L3 between the front suction gap S1 and the left and right suction gaps S3 are set wide, the airflow resistance is small. As a result, the propagation of the suction force from the intake port 12 is performed more in the front suction gap S1 and the left and right suction gaps S2 with less airflow resistance.

Incidentally, as shown in FIG. 1, the rectifying plate 4 is configured such that the rear side of the rectifying plate 4 is freely rotatable by the left and right support members 26 provided in the capture space M on the rear side of the hood portion 1. The form described above is supported in the capture space M by the left and right engagement / disengagement members 27 that are supported in a detachable manner and are provided in the capture space M on the front side of the hood portion 1. It comes to be mounted and arranged.
As a result, the oil and fat collected on the current plate 4 and the oil and fat attached to the top surface 13 (the inner surface of the oil panel 17) of the capture space M are wiped off, or the exhaust fan 2d of the exhaust device 2 is removed. When the fan casing 2b is removed from the inside of the fan casing 2b and washed in a sink or the like, as shown in FIG. 4, the rectifying plate 8 is rotated downward to the rear side (kitchen wall K1 side) of the hood portion 1 so that the capture space M is formed. It can be opened. Further, the rectifying plate 4 can be cleaned in a sink or the like by releasing the locked (hanging) state with respect to the support member 26 on the rear side.

≪Exhaust system configuration≫
Here, description will be made with reference to FIGS. 1 and 2 as appropriate.
As shown in FIG. 1, the exhaust device 2 is installed horizontally on the top plate 7 of the hood portion 1. The exhaust device 2 includes an exhaust box 2a attached to the top plate 7 by screws or the like, a fan casing 2b installed in the exhaust box 2a, and a fan motor 2c in the fan casing 2b. An exhaust fan (such as a centrifugal fan or a multi-blade fan) 2d that is supported and accommodated on the same axis is provided.

Then, a volute fan casing 2b installed horizontally (horizontal) in the exhaust box 2a is opened to a suction port 11 formed by a trumpet bell mouth and a top surface portion 13 of the capture space M. The suction port 12 is directly connected by the connection port member 14 that vertically passes through the communication port 10 opened in the top plate 7 of the hood portion 1, so that the suction force due to the rotational operation of the exhaust fan 2 d is generated by the suction port 12. From the air to the capture space M, and a suction flow velocity is generated vigorously in each of the suction gaps S1 to S3.
Incidentally, the connection port member 14 is formed into a cylindrical shape by drawing bending using a press or the like, and the upper end opening side is connected to the suction port 11 and the lower end opening side is connected to the intake port 12.

Next, the operation of the rectifying plate (rectifying plate body) 4 according to the present embodiment configured as described above and the range hood A including the rectifying plate 4 will be briefly described. Here, description will be made with reference to FIGS. 1 and 2 as appropriate.
When the exhaust fan 2d of the exhaust device 2 is rotated by one of three levels of strength by the operation switch 15, suction force is transmitted from the suction port 11 of the fan casing 2b through the connection port member 14 to the capture space M from the suction port 12. . At this time, the suction force propagated to the capture space M is that of the hood part 1 with the intervals L2 and L3 set wider than the suction gap S2 side on the rear side of the hood part 1 with the interval L1 set narrower. More propagation is performed on the suction gaps S1 and S3 sides on the front side and the left and right sides.
Thereby, compared with the rear side of the hood part 1 where the kitchen wall K1 exists over the entire height from the heating cooker B to the hood part 1, the suction gaps S1, on the front side and the left and right sides of the hood part 1 from which the contaminated air G is easily removed. In S3, since the suction flow velocity acts vigorously due to the suction force propagated more from the intake port 12, the polluted air G that spreads as it rises from the hot port b and the cooking pan C of the heating cooker B is released. Without being sucked and captured into the capture space M and exhausted outdoors.

  Moreover, as shown by the dashed-dotted line in FIG. 1, an illumination (lamp) 16 provided on the front side of the hood portion 1 so as to face the substantially central portion of the heating cooker B from the recess 4 a of the rectifying plate 4. Thus, the entire cooking device B can be illuminated uniformly and reliably from the bottom of the cooking pan C applied to the two hot mouths b on the front side as well as the hand of the cook.

And the contaminated air G which flies from the hot mouth b of the front two places and the cooking pan C of the heating cooker B which is used frequently is expanded space M1 on both sides of the capture space M located almost directly above. It is possible to catch and suck in and capture without fail.
That is, the expansion spaces M1 on both sides are located substantially directly above the two heat ports b on the front side, and more suction force is propagated from the intake port 12 so that the space between the extended edge portion 4b of the rectifying plate 4 is increased. In the expansion space M1 on both sides, the suction flow velocity acts on the suction gap S1 that is secured at the front, so that the polluted air G flying from the two hot ports b and the cooking pan C is not released. It can be caught securely, sucked in, and exhausted outdoors.
