Description

The present invention relates to a range hood, and more particularly to a range hood whose shape can be changed at a construction site.

A conventional range hood is equipped with a right exhaust type exhaust port or a left exhaust type exhaust port fixed to the main body part including a fan, or a range hood having a right exhaust type exhaust port is installed, Alternatively, whether to install a range hood having a left exhaust type exhaust port is selected depending on the position of the exhaust duct connection hole provided on the wall of the building. For this reason, which type of range hood is to be shipped should be shipped after confirming the condition of the construction site.

Here, if the range hood having exhaust ports with different exhaust directions is mistakenly shipped to the construction site as described above, it is necessary to order and ship again, which requires man-hours. As a countermeasure against this problem, it is conceivable that the right exhaust type exhaust port or the left exhaust type exhaust port can be selected at the construction site by rotating the main body part having the exhaust port and reversing it horizontally.

However, when the main body is turned left and right, the position of the fan changes, so the position of the suction port provided on the inner surface of the hood and the position of the fan do not function as a range hood, and eventually there is the problem of having to order and ship again. It was

Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to place an order again even if an order/shipping of a range hood that does not match the position of the exhaust duct connecting hole at the installation location is made. / It is to provide a range hood capable of selecting the position of the exhaust port according to the position of the exhaust duct connection hole at the construction site without shipping.

In order to solve the above problems, a hood, a main body part detachably attached to the upper part of the hood, having an exhaust port, and an inner panel having an opening provided on the inner surface of the hood and communicating with the main body part. And a closing plate that closes the opening and has a suction port, the main body part includes an impeller that generates a flow of air, and a suction port that includes the impeller inside and is compatible with the suction port. and has a fan casing having said exhaust port and compatible outlet, the inside, said having a fan casing internally comprising said impeller about a first axis perpendicular to the attachment portion of the hood When the main body is rotated, the suction port fits inside the opening, and when the closing plate is rotated about the second axis perpendicular to the opening, the suction port is The first axis and the second axis are aligned with each other so as to match the suction port when the main body is rotated, and the closing plate is detachable only with respect to the inner panel. A range hood , which is characterized by the above.
According to this, even if the range hood that does not match the position of the exhaust duct connection hole at the installation location is ordered/shipped, the range hood is not reordered/shipped at the construction site according to the position of the exhaust duct connection hole. A range hood whose position can be selected can be provided.

Further, the closing plate may be removable from the inner panel.
According to this, since the user can also attach and detach, the inside of the range hood can be easily cleaned.

Furthermore, when the main body is rotated 180 degrees about the first axis, the suction port is inside the opening, and when the closing plate is rotated 180 degrees about the second axis, the suction port is It may be characterized in that it is adapted to the suction port when the part is rotated.
According to this, when rotated 180 degrees, the positions of the suction port and the suction port in the front-rear direction do not significantly change, so that the size of the closing plate in the front-rear direction can be reduced.

Furthermore, the rotation center position of the impeller may be located on a straight line that bisects the main body in the front-rear direction.
According to this, regardless of the position of the right exhaust type or the left exhaust type exhaust port, the position of the suction port in the front-rear direction does not shift, so that there is no difference in the trapping amount and a stable trapping amount can be obtained. ..

Further, the inner diameter of the suction port may be equal to or smaller than the inner diameter of the suction port provided at a position facing the suction port.
According to this, the closing plate can receive the dripping oil from the fan casing. Further, since it is not necessary to separately provide an oil pan, the number of parts is reduced, which leads to a reduction in man-hours and further material costs can be reduced.

Furthermore, the blocking plate may be formed integrally with the bell mouth around the suction port.
According to this, since it is not necessary to separately provide the bell mouth, the number of parts is reduced, the number of steps is reduced, and the material cost can be further reduced.

Furthermore, the closing plate may be characterized by having a blocking portion that blocks the suction port from being attached to the inner surface panel when the suction port is in a position that does not match the suction port.
According to this, if it is installed in the wrong direction, the collection performance is adversely affected, but this adverse effect can be prevented.

As described above, according to the present invention, even if the range hood that does not conform to the position of the exhaust duct connecting hole at the installation location is ordered/shipped, the range hood of the exhaust duct connecting hole is not reordered/shipped at the construction site. It is possible to provide a range hood in which the position of the exhaust port can be selected according to the position.

Embodiments according to the present invention will be described below with reference to the drawings.
<First embodiment>
1 to 4 show a range hood 1 in the present embodiment according to the present invention. The range hood 1 is provided above the cooker, and has a thin inner panel 12 having an upward concave shape for collecting air including steam, oil smoke, etc. generated by cooking performed below or in the surroundings. The hood 10 and a main body 20 that is detachably attached to the upper part of the hood 10 and has a fan casing 23 including an impeller 22 that generates an air flow for sucking oily smoke and the like therein.

The main body part 20 has an exhaust port 21 connected to an exhaust duct (not shown) of the equipment at an upper part of a position on the left side in front view, and a motor cover 222 that covers a motor 221 that supplies power to an impeller 22 in front. In the upper part of the position slightly to the right of the center of the view. The range hood 1 shown in this figure is a so-called left exhaust type range hood. Since the main body 20 is attached to the hood 10 so as to be attachable to and detachable from the hood 10 at the site where the range hood 1 is installed, the position of the exhaust port 21 can be changed as described later. The fan casing 23 existing inside the main body 20 has a suction port 231 on the hood 10 side, and an air outlet 232 that opens upward and is adapted to communicate with the exhaust port 21. Further, the main body portion 20 has wall mounting portions 24 for mounting the range hood 1 on a wall surface at both ends on the back surface side.

The hood 10 includes a rectifying plate 50 below so as to face the inner panel 12. The current plate 50 is detachably attached to the inner surface panel 12, but when attached, forms a gap around the inner surface panel 12 for sucking air. The inner surface panel 12 has an opening 13 that communicates with the suction port 231 of the main body 20, and a closing plate 30 that closes the opening 13 is detachably provided to the inner surface panel 12. Since the closing plate 30 can be detached by the user, the inside of the range hood can be easily cleaned. The closing plate 30 has a circular suction port 31 that is eccentric from the center of the closing plate 30 and has a center that coincides with the rotation center of the impeller 22. The suction port 31 will be compatible with the suction port 231. When the blocking plate 30 is attached, it is preferable that the center of the suction port 31 of the blocking plate 30 be located on the extension line of the rotation shaft of the motor 221. According to this, when the impeller 22 is driven, the force can be evenly sucked without being biased, so that an extra load is not applied to the motor 221.

The rotation of the impeller 22 causes a flow of air. The air including oil smoke and the like sucked from the gap between the inner surface panel 12 and the flow regulating plate 50 reaches the inside of the impeller 22 through the suction port 31 of the closing plate 30, and the inside of the blade of the impeller 22 and the fan casing 23. After the oil is adhered to and purified, the air is guided from the outlet 232 to the exhaust port 21 and discharged to the outside or the like. A bell mouth 32 having a trumpet shape is provided around the suction port 31 in order to guide the air so that the air can be smoothly sucked in with low resistance. The closing plate 30 is formed integrally with the bell mouth 32 around the suction port 31. According to this, since it is not necessary to separately provide the bell mouth, the number of parts is reduced, the number of steps is reduced, and the material cost can be further reduced.

The main body 20 and the hood 10 are detachably attached by the flange portion 25 of the main body 20 engaging with the attachment portion 11 of the hood 10 or being screwed. Since the screw can be easily removed because of this, the installer of the range hood 1 temporarily removes the main body unit 20 from the integrated hood 10 and rotates the main body unit 20 to exhaust the exhaust port. After changing the position of 21, the range hood 1 can be integrated with both again.

5 to 9 show the main body portion 20 in this embodiment. The main body 20 is commonly used for the above-described left exhaust type range hood and right exhaust type range hood. The main body portion 20 is attached inside the fan casing 23 including the impeller 22 driven by the motor 221, and the upstream side of the fan casing 23 in the flow of air and the downstream side of the closing plate 30, and the suction port 231. And a blind plate 233 having a through hole 236 which is the same or larger than the suction port 231.

The fan casing 23 sucks air containing oily smoke and the like from the suction port 231 and blows out the air after removing the oil component with the blades or the like from the blowout port 232. The center of rotation of the impeller 22 is preferably near the center of the hood 10 in the left-right direction in consideration of suction balance. Then, the suction port 231 is located in the vicinity of the center position on the left and right of the inner panel 12, while the outlet port 232 is located in the vicinity of the edge portion away from the center position of the range hood 1 in consideration of the structure of the fan casing 23. It will be. As a result, the exhaust port 21 that matches the position of the air outlet 232 and is also located near the edge of the range hood 1. In addition, in the present embodiment, the suction port 231 is near the center in the left-right direction with respect to the body portion 20, but is eccentric from the center position of the body portion 20. Further, the fan casing 23 is provided with a drain hole 235 on the bottom surface for dropping the oil component collected by the blades of the impeller 22 or the oil component attached to the inner wall of the fan casing 23 and accumulated inside.

The blindfold plate 233 is larger than the opening portion 13 of the inner surface panel 12, and even when the closing plate 30 that closes the opening portion 13 is removed, the blindfold plate 233 is blindfolded so that the inside of the main body portion 20 cannot be seen and drops from the drain hole 235. Receive oil. The blind plate 233 is provided with an oil drain hole 234 to further drop oil on the blocking plate 30. Because of this, the blindfold plate 233 gives the user a clean impression even when the closing plate 30 is removed. In addition, since the blind plate 233 has a size that covers the fan casing 23 in a bottom view, oil leaking to the outside of the fan casing 23 and adhering to the fan casing 23 also drops into the blind plate 233 and flows to the closing plate 30. It can be collected. In addition, since the oil that is captured inside the range hood 1 can be surely flowed to the closing plate 30 and the user can remove the closing plate 30 and collect the accumulated oil, the oil is accumulated inside the range hood 1 and an odor is generated. You can prevent the situation.

When switching between the left exhaust type range hood and the right exhaust type range hood, the main body portion 20 is perpendicular to the mounting portion 11 on the upper surface of the hood 10 and is at the center position of the depth (D) and the width (W). (In other words, the first axis AX1 of the intersection of the diagonal lines of the rectangle) is rotated.

FIG. 10 shows the closing plate 30. The closing plate 30 is commonly used for the left exhaust type range hood and the right exhaust type range hood described above. The closing plate 30 is attached to the opening 13 of the inner panel 12 in an airtight and detachable manner. The closing plate 30 has a suction port 31 so as to fit the suction port 231.

The closing plate 30 is formed integrally with the bell mouth 32 around the suction port 31 in order to reduce the number of steps and the material cost. The closing plate 30 has a recessed portion that is recessed on the lower side (upstream side of the flow of air). The oil dripping from the filter and/or the fan casing 23 collects in the concave portion, so that the oil does not spread to the closing plate 30, and the oil collected when the closing plate 30 is removed is unlikely to spill.

When switching between the left exhaust type range hood and the right exhaust type range hood, the closing plate 30 is perpendicular to the opening 13 of the inner panel 12, and is at the center position of the depth (d) and the width (w). (In other words, it is rotated about the second axis AX2 of the intersection of the diagonals of the rectangle).

11 and 12 show the hood 10. The hood 10 is commonly used for the left exhaust type range hood and the right exhaust type range hood described above. The hood 10 appropriately has a claw portion 111 for sandwiching the flange portion 25 and a screw hole for fastening the flange portion 25 with a screw on an upper surface of the body portion 20 in the vicinity of abutment with the flange portion 25.

A case of switching from the left exhaust type range hood to the right exhaust type range hood will be described with reference to FIGS. 13 and 14. FIG. 13(A) shows the left exhaust type range hood 1 shown in FIG. FIG. 13B shows a case where the screw that attaches the body portion 20 to the hood 10 is removed and the hood portion is removed from the attachment portion 11.

FIG. 13C shows a case where the main body 20 is rotated 180 degrees about the first axis AX1 perpendicular to the mounting portion 11 of the hood 10. The flange portion 25 of the main body portion 20 has a front-rear and left-right symmetrical shape, but the wall mounting portion 24 is not front-rear symmetrical. Therefore, FIG. 13D shows a case where the wall mounting portion 24 that has come to the front side is removed and reattached to the back side.

FIG. 13E shows a case where the closing plate 30 is rotated 180 degrees about the second axis AX2 perpendicular to the opening 13. Then, FIG. 13(F) shows a case where the flange portion 25 of the main body portion 20 is attached to the attachment portion 11 of the hood 10 and attached by screwing, and the right exhaust type range hood 1 is shown.

14(A) to (C) show the same left exhaust type range hood 1 as in FIG. 13(A), and FIGS. 14(D) to (F) show the same right exhaust type range hood as in FIG. 13(F). The range hood 1 is shown. Even when the left exhaust type range hood is changed to the right exhaust type range hood, that is, the main body unit 20 is rotated 180 degrees about the first axis AX1 perpendicular to the mounting portion 11 of the hood 10. In addition, even when the closing plate 30 is rotated 180 degrees about the second axis AX2 perpendicular to the opening 13, the fan casing 23 that is eccentric from the center position of the main body 20 is The suction port 231 fits inside the opening portion 13, and the suction port 31 that is eccentric from the central position of the closing plate 30 fits the suction port 231 when the main body unit 20 is rotated, so that the first axis AX1. And the second axis AX2 coincide. With such a structure, even if a range hood that does not conform to the location of the exhaust duct connection hole at the installation location is ordered/shipped, the range hood is not ordered/shipped again according to the location of the exhaust duct connection hole at the construction site. It is possible to provide a range hood in which the position of the exhaust port can be selected.

In addition, in the present embodiment, the example of rotating 180 degrees has been described, but it goes without saying that the invention is not limited to this. In the present embodiment, the main body portion and the closing plate are rectangular, but if the main body portion and the closing plate are square, for example, the position of the exhaust port can be changed by rotating 90 degrees according to the position of the exhaust duct connection hole. Can be selected. When the main body and the closing plate are circular, the position of the exhaust port can be selected by freely rotating the exhaust duct connecting hole depending on the position.

The main body 20 is rotated 180 degrees about the first axis AX1 perpendicular to the mounting portion 11 of the hood 10, and the closing plate about the second axis AX2 perpendicular to the opening 13. Even if 30 is rotated 180 degrees, the range in which the suction port 231 moves falls within the range inside the opening 13, and the suction port 31 has a structure that fits the suction port 231 when the main body 20 is rotated. With this, the positions of the suction port and the suction port in the front-rear direction do not significantly change, and thus the size of the closing plate in the front-rear direction can be reduced.

Further, as shown in FIG. 15, the inner diameter ID1 of the suction port 31 of the closing plate 30 is preferably equal to or less than the inner diameter ID2 of the suction port 231 of the fan casing 23 provided at a position facing the suction port 31. According to this, the closing plate 30 can receive the dripping oil from the fan casing 23. Further, since it is not necessary to separately provide an oil pan, the number of parts is reduced, which leads to a reduction in man-hours and further material costs can be reduced.

Further, it is preferable that the closing plate 30 is not attached to the inner surface panel 12 when the suction port 31 is in a position that does not match the suction port 231. For example, in the present embodiment, the blind plate 233 has the blocking portion 237 that is a convex portion on the lower side (closer plate 30 side), so that when the suction port 31 does not match the suction port 231, this blocking is prevented. Since the portion 237 collides with the bell mouth 32 of the closing plate 30, the closing plate 30 cannot be attached to the inner surface panel 12. According to this, if it is installed in the wrong direction, the collection performance is adversely affected, but this adverse effect can be prevented.

Further, as a modification of the present embodiment, the rotation center position of the impeller may be located on a straight line that bisects the main body in the front-rear direction. According to this, regardless of the position of the right exhaust type or the left exhaust type exhaust port, the position of the suction port in the front-rear direction does not shift, so that there is no difference in the trapping amount and a stable trapping amount can be obtained. ..

It should be noted that the present invention is not limited to the illustrated embodiments, and can be implemented with a configuration within a range not departing from the contents described in each item of the claims. That is, the present invention is mainly illustrated and described with respect to particular embodiments mainly, but with respect to the embodiments described above, without departing from the scope of the technical idea and the object of the present invention, the shape, Those skilled in the art can make various modifications in the material, quantity, and other detailed configurations.
