Description

  The present invention relates to a range hood used in a kitchen or the like.

  As a prior art, for example, in Patent Document 1, a square range hood that covers a portion directly above a kitchen table heating device (a gas stove, a range cooker, or the like) is disposed, and smoke generated in the heating unit is sucked therefrom. is there. However, in this case, smoke rising toward the large opening can be effectively sucked, but smoke rising out of the opening may not be sucked well. In addition, the structure is complicated and it is difficult to clean.

  Moreover, the range hood which arrange | positioned the horizontal plate-shaped suction part above the heating part is also known (patent document 2). In this case, smoke can be received and sucked in a relatively large area, but there is a drawback that smoke tends to leak sideways from the outer edge of the plate-like suction part. In addition, since there are several suction portions, there is a drawback that cleaning of the suction portion is difficult.

Japanese Patent Laid-Open No. 9-222249 JP 2005-315546 A

  In view of the above circumstances, an object of the present invention is to provide a novel range hood that enhances the smoke collecting function of the range hood and is excellent in design and aesthetics.

Means for Solving the Problems and Effects of the Invention

The present invention for solving the above problems is as follows.
A kitchen range hood that is disposed near the upper part of a cooking heater in kitchen furniture and discharges smoke, steam and other things (hereinafter simply referred to as smoke) generated by cooking to the outside,
A trunk located in the center,
An umbrella-shaped body that extends laterally around the trunk part with a part of the trunk part projecting downward, and whose outer peripheral part away from the trunk part is lower than the joint part with the trunk part When,
A plurality of suction holes formed on the outer surface of the trunk protruding downward from the umbrella-like body;
A suction drive unit provided in the body and for sucking smoke from the suction hole;
A smoke passage that is provided in the body and guides the smoke sucked from the suction hole to the outside;
It is characterized by including.

  By comprising as mentioned above, the smoke which moves toward the center part of a range hood is suck | inhaled directly from a suction hole (1st step suction). In addition, the smoke that diffuses from the heating device and rises in the peripheral portion is once received by the umbrella-like body, and then guided to the suction hole in the central portion on the inner surface of the umbrella-like body, and is sucked therefrom. There is a two-stage suction effect (second stage suction). Thus, since the generated smoke can be accurately sucked, the suction portion may be provided at one place with respect to the trunk portion which is the main body, and even a sirocco fan (suction drive portion) having a small size can be effectively applied.

In addition, the umbrella body symmetrically spreads on both sides of the trunk, and smoke rising from below is received on both sides and led to the suction hole in the trunk along the lower surface of the umbrella. It is.
In general, since the kitchen table has a longitudinal shape, the upper portion of the heating unit of the kitchen table can be covered by extending symmetrically from the body to both sides so as to correspond to the kitchen table. And even if there is a time when smoke rising from the heating device spreads in the kitchen table arranged horizontally, the range hood of the present invention can catch this, and the kitchen table is located just below the trunk. Even when the range is not located, the effect of catching smoke widely in the lateral direction of the trunk is expected.

  Furthermore, the lower end of the body portion of the range hood is provided with a guide surface that guides smoke rising from below the body portion to a suction hole formed on the outer peripheral surface of the body portion. Smoke rising from below is guided to the side of the guide surface by installing this guide surface, and can be effectively guided to the suction hole of the trunk at the top of the guide surface.

  In addition, the body portion of the range hood has a cylindrical shape, and a plurality of suction holes are formed on the belt-like outer peripheral surface of the cylindrical portion located below the cylindrical body portion, so that the suction holes are arranged in a cylindrical shape. Therefore, smoke can be sucked over the entire circumference.

  And the guidance surface which becomes convex downward is formed in the lower end of a trunk part. Since the guide surface is convex downward in this way, smoke can be more accurately received over the side end than the flat guide surface, and can be guided to the suction hole of the trunk at the top of the guide surface.

In addition, the umbrella-like body is horizontally long in the left-right direction and short in the front-rear direction, is curved so as to be convex upward while spreading in a wing shape symmetrically in the left-right direction, and is also convex upward in the front-rear direction. It is curved to form an inverted container shape, and smoke is stored in the inverted container-shaped space, and the smoke is guided to the suction hole of the trunk and sucked.
Thus, since it forms an inverted container shape, the collection function which sucks the stored smoke into the suction hole while storing the smoke there is strong. And since it is a structure long in the left-right direction, the smoke which moved away from the heating apparatus can be widely received. Further, in the front-rear direction, the smoke rising to the center can be directly sucked, so there is no problem even if it is short. By adopting such a form, a novel structure excellent in design and aesthetics can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings.

  The whole structure of the range hood 1 of 1st Example is demonstrated in FIG. 1 showing the whole kitchen. As shown in FIG. 1, a system kitchen 41 in which a heating device 40 is incorporated in a kitchen is installed. And the range hood 1 is attached just above the heating apparatus 40 so that the longitudinal direction of the system kitchen 41 and the longitudinal direction of the umbrella-shaped body 3 may become parallel. The range hood 1 has a function of sucking smoke 30 generated from food (not shown) cooked by the heating device 40 from the suction unit 5 and discharging it to the outdoors. Here, of the smoke 30 rising from the heating device 40, the smoke rising near the center of the lower surface portion 13 of the range hood 1 is the smoke 31 at the center, and the smoke rising near the outside in the longitudinal direction of the umbrella 3. Is the smoke 32 in the periphery.

  The range hood 1 according to the present embodiment includes a cylindrical body 2 and an umbrella body 3 coupled to the body 2 as a main body. The body 2 has a cylindrical shape, and there is a cylindrical suction part 5 in which a number of suction holes 21 are formed on the belt-like outer peripheral surface of the lower part of the cylindrical body 2. A semi-spherical upper surface 12 that is convex is provided, and a semi-spherical lower surface that includes a guide surface 4 that guides smoke 31 at the center that is convex downward to the suction portion 5 below the suction portion 5. 13 is installed. As shown in FIG. 2 representing the flow of smoke, a sirocco fan 9 is disposed inside the body 2, a smoke exhaust passage 11 is installed on the discharge side of the sirocco fan 9, and a duct portion 6 is provided in the smoke exhaust passage 11. Are combined. Further, as shown in FIG. 3, the lower surface of the range hood 1 has a lighting device 10 installed at the center of the lower surface portion 13 inside the lower surface portion 13 of the trunk portion 2, and is received at a position slightly away from the lighting device 10. Part 8 is installed. As is apparent from FIG. 1 representing the entire kitchen, the receiving unit 8 is located around the center of the semispherical surface of the lower surface 13 in the front view.

  Further, as shown in FIG. 1 representing the entire kitchen, the trunk 2 is fixed to be suspended from the ceiling 42 by a support 7, and the support 7 penetrates the upper surface 12 and is coupled to the trunk 2. Yes. As shown in FIG. 4, the upper surface of the range hood 1 has four through portions of the support portion 7 on the upper surface portion 12 of the trunk portion 2 and is disposed at a position close to the circumferential end of the trunk portion 2. . Further, the center position of the duct portion 6 is installed at a position eccentric from the center position of the upper surface portion 12 of the trunk portion 2.

  The umbrella body 3 installed so as to cover the suction part 5 of the trunk portion 2 is symmetrical in a wing shape so that the longitudinal direction of the system kitchen 41 and the longitudinal direction of the umbrella body 3 are parallel with respect to the trunk portion 2. In the form of an inverted container that is formed so that the height decreases as it moves away from the body part 2, is longer in the left-right direction, is shorter in the front-rear direction, and is convex upward in both the left-right direction and the front-rear direction. is there. Further, as is apparent from FIG. 3 and FIG. 4, which show the lower surface and the upper surface of the range hood 1, the umbrella-shaped body 3 has the wing-shaped central portion 16 of the wing-shaped configuration that is the narrowest with respect to the top and bottom. It is a form which becomes wide as it goes to the both side parts 15, and both right and left ends are circular. In other words, the elliptical shape has a constricted shape in which both ends of the major axis and the minor axis on the minor axis side are formed in an arc shape.

  Such a range hood 1 of the present invention is particularly effective for, for example, a face-to-face kitchen stand (island kitchen), and is disposed so as to cover the upper portion of the kitchen stand. And unlike a normal range hood with a cover connected to the ceiling, the range hood 1 itself appears to float in the air alone, like a manta swimming in the sea. It is novel compared to the other, and it gives a sense of beauty.

  In FIG. 2 which is a front sectional view showing the flow and configuration of smoke in the range hood 1, the smoke 31 at the center of the smoke 30 generated from the ingredients cooked by the heating device 40 is the lower side of the trunk 2. It is directed toward the convex guide surface 4 of the lower surface portion 13 installed at the side, further guided from the lower end of the guide surface 4 to the side end thereof, and then sucked from the suction hole 21 of the suction portion 5 above the side end. Further, the smoke 32 in the peripheral portion is temporarily received by the umbrella 3. Thereafter, the smoke 32 is guided from the curved inner surface of the umbrella-shaped body 3 to the central portion of the wing-shaped side portions 15, and further to the wing-shaped central portion 16 where the trunk portion 2 is located at the center of the umbrella-shaped body 3. It flows in a diagonally upward direction. The peripheral smoke 32 guided to the wing-shaped central part 16 is sucked from the suction hole 21 of the suction part 5 and passes through the smoke exhaust passage 11 via the sirocco fan 9 and the duct part 6 together with the smoke 31 of the central part. It is discharged to the outdoors. The duct portion 6 is installed so as to penetrate the ceiling 42.

  FIG. 3 is a diagram showing the bottom surface of the range hood 1, and the lighting device 10 is installed at the center of the lower surface portion 13, which helps improve the workability of a person who uses the heating device 40 for cooking. A receiving unit 8 that receives signals for starting and stopping the sirocco fan 9 as a suction device and turning on and off the lighting device 10 is also provided on the lower surface 13. In addition, since the guide surface 4 of the lower surface part 13 and the inner surface 17 of the umbrella-shaped body 3 are mirror-finished, since the light generated from the illumination device 10 is reflected on those surfaces, the brightness is further improved. . In addition, the mirror finish has an effect of easily removing dirt even when the umbrella-like body side face 17 is stained with oil or the like.

  FIG. 4 is a plan view of the range hood 1, and the body portion 2 is fixed at four places by the support portion 7. Thus, since the trunk | drum 2 is suspended below the ceiling 42 (refer FIG. 1), the range hood 1 itself appears to be floating in the air, and it is novel and aesthetics are also improved. In addition, the support part 7 can be changed to 3 or 5 instead of 4 and can be changed depending on the specification state. Moreover, the position of the duct part 6 installed in the position eccentric from the center position of the upper surface part 12 can also be changed to the center, and it can be changed as appropriate depending on the state of use.

  Here, as shown in FIG. 3 and FIG. 4, the umbrella-shaped body 3 has a constricted shape, so that the wing-like side portions 15 are formed against the smoke 32 in the peripheral portion away from the heating device 40 in the lateral direction. Since it is wide, the area for receiving the smoke 32 in the peripheral portion can be widened, and the smoke 32 can be received in a wide range. Further, in the front-rear direction, the smoke 31 rising to the center can be directly sucked, so there is no problem even if it is short. In addition, as shown in FIG. 1, the convex spherical guide surface 4 is exposed corresponding to the constricted shape when viewed from the front, and by adopting such a form, a novel structure excellent in design and aesthetics is obtained. be able to.

  FIG. 5 is a right side view of the range hood 1, and the body portion 2 is formed by connecting the rear cover 19 and the front cover 20, which are two semicircular arc-shaped parts, at a connecting portion 14 using, for example, a magnet (magnet catch). It is fixed with. In addition to the magnet catch, a ball catch using a ball can be used for the catch mechanism, and can be changed as appropriate. With such a structure, the rear cover 19 and the front cover 20 can be easily separated, and inspection, cleaning, and the like can be easily performed.

FIG. 6B is an enlarged view of the connecting portion 14. In the rear cover 19, the magnet portion 23 a is fixed to the L-shaped bracket 24, and the L-shaped bracket 24 is fixed to the rear cover 19 by rivets 25. The front cover 20 is provided with a magnet part 23 b at a position corresponding to the magnet part 23 a of the rear cover 19. Further, the tip of the rear cover 19 is bent in an L shape in order to prevent lateral displacement during installation. FIG. 6C is a front view of the rear cover 19 and the front cover 20, and the rear cover 19 has four rectangular holes 26 a vacated for coupling the magnet portion 23 a and the magnet portion 23 b. The front cover 20 is provided with eight circular holes 26b having a larger diameter corresponding to the attachment position of the rivet 25 of the rear cover 19. The upper and lower ends of the rear cover 19 and the front cover 20 are crushed and bent 27 for safety. Then, as shown in FIG. 6D, the components stored in the body 2 can be inspected by pulling the rear cover 19 and the front cover 20 apart.

  FIG. 7 is a diagram illustrating a state of the trunk portion 2 in which the umbrella body 3 is omitted in the range hood 1. The suction part 5 is provided on the belt-like outer peripheral surface of the lower end portion of the body part 2 and can suck the smoke 30 from all directions around the belt-like outer peripheral surface. Thus, the suction part 5 for sucking smoke can be formed in a simple form with only one place in the entire circumferential direction, and since the suction part 5 is provided in one place, cleaning is easy.

FIG. 8A is an enlarged view of FIG. A number of suction holes 21 are formed in the suction portion 5. The smoke in the center is guided to the upper end of the guide surface 4 along the guide surface 4 of the lower surface portion 13 and is sucked from the suction hole 21 so as to wrap around the lower surface protrusion 22. The smoke 32 in the peripheral portion is once received by the umbrella body 3 and then guided to the vicinity of the wing-shaped central portion 16 where the suction portion 5 is located obliquely upward by the inner surface 17 of the umbrella state 3 and sucked from the suction hole 21. The
FIG. 8B is a plan view of the umbrella-shaped body 3, and a locking hole 29 for attaching and detaching the cylindrical suction portion 5 is attached. Then, as shown in FIG. 8 (a), the suction protrusion 5 installed on the upper portion of the suction portion 5 is fitted into the stop hole 29, so that the suction portion 5 is detachably attached to the umbrella-shaped body 3.
FIG. 8C is an enlarged view of a portion A in FIG. 8A, and is a cross-sectional view of the main part showing the attachment / detachment structure between the suction portion 5 and the lower surface portion 13 having the guide surface 4 disposed below the suction portion 5.

Further, an inner bent portion 52 is provided at the upper portion of the guide surface 4, and the engaging piece 53 attached to the inner bent portion 52 is engaged with the engaging hole 51, so that the lower surface portion 13 becomes the suction portion. 5 is attached. For this reason, the dirt adhering to the suction part 5 can be removed by removing the engagement hole 51 and the engagement piece 53 and cleaned.

FIG. 9 is a plan view of the range hood 1, and the horizontally long system kitchen 41 located below is hidden by the umbrella 3 of the range hood 1. A portion indicated by a dotted line in the center of the drawing hidden by the umbrella 3 indicates a heating device 43 installed at the lower center of the range hood 1, and a portion indicated by a dotted line on the left side of the drawing shows a heating device 44 installed in the left direction. The case where it was done is shown.
In a general installation state, the heating device 43 is located in the center of the system kitchen 41, and the trunk portion 2 of the umbrella 3 is located immediately above the heating device 43. In this case, the smoke that has risen to the vicinity of the umbrella 3 is not so diffused because it is close to the suction part 5 of the trunk 2, and even if the size of the umbrella 3 in the front-rear direction is narrowed, the smoke is efficiently sucked. can do.

On the other hand, it is preferable that the umbrella-shaped body 3 is located above the horizontally long system kitchen 41 in order to achieve a beautiful design. However, depending on the system kitchen 41, the heating device 44 is arranged on one side of the entire center. In some cases, the position of the heating device 44 does not coincide with the center of the body 2.
If there is no heating device 43 directly under the range hood 1, for example, even when it is shifted to the left as shown in the heating device 44, the wing-like side portions 15, which are portions away from the trunk portion 2 of the umbrella 3, Since the dimensions are large in the front-rear direction, the smoke 30 can be received by the umbrella 3. Due to this effect, the smoke 30 or its steam, oil, etc. when the body 2 of the range hood 1 cannot be installed above the heating device 44 by design or when the cooked food is left and right. You can catch it.

As described above, the range hood 1 of the present invention can be arranged above the entire horizontally long system kitchen, and is very easy to install on an island type kitchen stand. Since the umbrella-shaped body 3 of the range hood 1 can cover and narrow the width of the portion where the central body 2 is installed, the umbrella-shaped body 3 is seen from the side when the range hood 1 is viewed together with the kitchen stand. Since it is so high that the end of the body part 2 can be seen at the center, and has a shape that extends obliquely downward as it expands laterally, it is innovative in design.
In particular, the umbrella-like body 3 extending like a wing around the trunk 2 is like a fin of a manta ray swimming in the sea, and is installed so as to be suspended from the ceiling 42 by the support part 7 so that the fin spreads in the air and floats. Looks like.

  The trunk portion 2 of the range hood 1 can be extended to an appropriate length in the vertical direction so that the ceiling 42 and the trunk portion 100 overlap with each other as shown in FIG. Is effective when hiding the inside of the ceiling 42 so as not to show the duct portion 6 and the support portion 7.

FIG.11 (b) represents the front view of another form, and FIG.11 (c) represents the side view of another form, respectively. It is very simple, with a single plate projecting upward in the front-rear and left-right directions.

  12 (a) and 12 (b) each have a rectangular shape in the bottom view of FIG. 11, and (a) is smaller, and (b) is larger. Yes. In both cases, the umbrella states 102 and 103 are convex upward in the front-rear direction and the left-right direction, and the design effect is high in a form different from the above embodiment.

  In another embodiment shown in FIG. 13, as shown in FIG. 13A, which is a plan view, the trunk portion 104 has a rectangular tube shape, and the umbrella body 105 has a rectangular shape. Further, as is apparent from FIG. 13B, which is a front half sectional view, the inside of the umbrella 105 is slightly curved toward the trunk 104, which is the central part, to induce smoke to the central part. The umbrella 105 is very thin when viewed from the front, and the design effect is high.

  In another embodiment shown in FIG. 14, the entire surface of the lower surface portion 106 of the trunk portion 2 is a suction hole 107, and the smoke 31 at the center rising from the lower side of the range hood 1 is directly passed through the suction hole 107. The suction area can be widened.
