Description

Technical Field

[0001] The present invention relates to a range hood.

Background Art

[0002] Conventionally, this type of range hood is known to include a hood having an air inlet, a rectifying plate disposed on the lower surface of the hood for efficiently guiding air to the air inlet, and a locking portion for attaching and detaching the rectifying plate to and from the hood (see, for example, Patent Document 1).

[0003] Hereinafter, the range hood will be described with reference to FIG. 11. Note that FIG. 11(a) shows the unlocked state of the locking portion, and FIG. 11(b) shows the locked state of the locking portion. The locking portion 103 includes a rectifying plate front-side engaging portion 109 on the rectifying plate 102 side, a hood front-side engaging portion 107 on the hood 101 side, and a permanent magnet 116. The rectifying plate front-side engaging portion 109 includes a first upright portion 110, a first extending portion 111, and a third extending portion 112. An insertion portion 119 is formed by the rectifying plate 102, the first upright portion 110, and the first extending portion 111. The hood front-side engaging portion 107 is disposed at the front end of the front surface of the hood 101 and engages with the rectifying plate front-side engaging portion 109. The hood front-side engaging portion 107 includes a second upright portion 104, a second extending portion 105, and a fourth extending portion 106. The permanent magnet 116 is fixed to the lower surface of the second extending portion 115. Due to the magnetic force of the permanent magnet 116, the upper surface 108 of the rectifying plate and the lower surface 118 of the magnet portion are joined, and the rectifying plate 102 can be held on the hood 101. Further, in a state where the rectifying plate 102 is held on the hood 101, by horizontally moving it toward the back surface, the permanent magnet 116 is inserted into the insertion portion 119. At that time, the first extending portion 111 and the upper surface 114 of the second extending portion come into contact. The second extending portion 105 and the permanent magnet 116 can be inserted into the insertion portion 119 until the opposing side surface 117 of the upright portion is joined to the first upright portion 110 by magnetic force. In this way, when the rectifying plate front-side engaging portion 109 and the hood front-side engaging portion 107 engage with each other, the locking portion 103 is in the locked state.

[0004] [Patent Document 1] Japanese Patent Publication No. 2021-089108 [Overview of the project] [Problems that the invention aims to solve]

[0005] In conventional range hoods, the locking mechanism requires the baffle plate to be fixed to a locking body with a magnet located on the underside of the hood, while simultaneously being manually pushed against the back of the hood to maintain the locked state.

[0006] A range hood is a type of ventilation device installed above cooking appliances and used to exhaust oil fumes and other grease generated during cooking from the inside to the outside. As a result, a large amount of oil fumes accumulate on the rectifier plate, oil filter that collects oil, and the fan mounted on the exhaust blower. If regular cleaning is not performed, the exhaust performance and oil collection performance of the range hood will deteriorate.

[0007] Therefore, when removing the rectifier plate from the hood and cleaning the rectifier plate, oil filter, fan, etc., there is a possibility that when reattaching the rectifier plate to the hood, the operation may end with the rectifier plate fixed to the magnet on the locking part, and the locking part on the front of the rectifier plate may be forgotten to be hooked onto the locking part on the hood.

[0008] Even in this condition, if the magnetic force of the magnet is strong enough, the rectifier plate can be held in place without falling. However, it is easy to imagine that if force is suddenly applied to the rectifier plate, its fixings may come loose. If the rectifier plate falls, there is a possibility that it will be damaged.

[0009] Therefore, the present invention aims to solve the above-mentioned conventional problems and to provide a range hood that allows for easy and reliable hooking of a locking body provided in front of the rectifier plate onto a locking body provided on the hood. [Means for solving the problem]

[0010] To achieve this objective, the range hood according to the present invention comprises a hood that draws in air from below, a rectifier plate attached to the lower part of the hood, and a front locking part that locks the rectifier plate to the hood on the front side of the hood, having a hood-side support part provided on the hood and a rectifier plate-side support part provided on the rectifier plate, wherein the front locking part locks the rectifier plate-side support part to the hood-side support part via the horizontal movement of the rectifier plate from the front to the rear, and the hood-side support part is provided with a magnet that pulls the rectifier plate-side support part from the front to the rear, thereby achieving the intended objective. [Effects of the Invention]

[0011] According to the present invention, a range hood is provided that prevents the baffle plate from falling by making it easy and reliable to hook the baffle plate side support part, which is provided in front of the baffle plate, onto the hood side support part, which is provided in front of the hood.

Mode for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0014] (Embodiment 1) Using FIGS. 1 and 2, an outline of the configuration of the range hood according to the present invention will be described. Note that FIG. 1 shows the appearance of the range hood with the front locking part and the rear locking part in the locked state, and FIG. 2 shows the appearance of the range hood with only the front locking part released and the rectifying plate opened.

[0015] The range hood 1 is installed above a cooking appliance or the like, and is a type of ventilation device that discharges air containing oil fumes and the like generated during the cooking process from the indoor to the outdoor.

[0016] The range hood 1 includes an exhaust blower (not shown) and an exhaust port communicating with the outdoor. The air sucked in from the intake port 8 described later by the exhaust blower is exhausted from the exhaust port to the outdoor.

[0017] The range hood 1 includes a hood 2, a rectifying plate 3, a front locking part 5, and a rear locking part 6.

[0018] The hood 2 includes an intake port 8 for sucking air into the hood lower surface 7 and an operation part 4.

[0019] The intake port 8 is a rectangular opening. Further, an oil filter may be provided at the opening of the intake port 8 as an oil collecting mechanism for collecting oil contained in the air.

[0020] The operation unit 4 includes buttons for performing operations such as turning on / off the operation of the range hood 1 and adjusting the air volume, and is disposed at the center in the left-right direction on the front surface facing a person when the person operates the range hood 1.

[0021] The rectifying plate 3 is a metal part formed by machining such as punching and bending of sheet metal.

[0022] The rectifying plate 3 is disposed below the lower surface 7 of the hood for the purpose of controlling the flow of air sucked into the air inlet 8, and is locked to the hood 2 via the front locking portion 5 and the rear locking portion 6.

[0023] When the lower surface 7 of the hood is viewed from directly below, when the opening area of the air inlet 8 is S1, the area of the rectifying plate 3 is S2, and the area of the lower surface 7 of the hood is S3, the size relationship is S1 < S2 < S3, the hood 2 covers the rectifying plate 3, and the rectifying plate 3 is arranged to cover the air inlet 8.

[0024] The range hood 1 has a gap for guiding air to the air inlet 8 between the rectifying plate 3 and the lower surface 7 of the hood, and the airflow sucked into the gap from the periphery has an increased speed. Thereby, since the air heated by the cooking and rising can be efficiently guided to the air inlet 8, an effect of preventing the air containing oil fumes and the like from spreading in the room can be expected.

[0025] The front locking portion 5 and the rear locking portion 6 are for detachably locking the rectifying plate 3 to the hood 2. By detachably locking the rectifying plate 3, not only the rectifying plate 3 but also the oil filter, the fan of the exhaust blower, etc. can be taken out for cleaning.

[0026] Note that the mechanism and procedure for attachment and detachment will be described later.

[0027] The front locking portions 5 are arranged one by one at the front end of the rectifying plate 3 so as to be symmetric with respect to the center of the range hood 1. The rectifying plate side support portion 44 and the hood side support portion 45 constituting the front locking portion 5 will be described later.

[0028] The rear locking parts 6 are positioned one by one symmetrically from the center of the range hood 1 at the rear end opposite the front end of the rectifier plate 3 where the front locking parts are located.

[0029] In this way, by positioning the rear locking portion 6 at the rear end of the rectifier plate 3, i.e., one end, and the front locking portion 5 at the front end of the rectifier plate 3 opposite the rear locking portion 6, i.e., the other end, the rectifier plate 3 is held by the hood 2 at its ends. As a result, the range hood 1 can stably hold the rectifier plate 3, and thus the effect of reducing noise caused by vibrations of the rectifier plate 3 during the operation of the range hood 1 is obtained.

[0030] Next, the configuration of the front locking section 5 will be explained using Figures 3, 4, and 5. Figure 3 shows the locked state of the front locking part 5 and the rear locking part 6, which are located to the right of the center of the range hood 1, as viewed from the right side of the range hood 1. Figure 4 shows the locked state of the front locking part 5. Figure 5 shows the state in which the claw part 11 provided on the rectifier plate side support part 44 is engaged with the front recess 16 of the hood side support part 45 in the front locking part 5. The front recess 16 is a space formed facing forward in the groove part 12, which will be described later.

[0031] The front locking portion 5 includes a rectifier plate side support portion 44 on the rectifier plate 3 side and a hood side support portion 45 on the hood 2 side.

[0032] The rectifier plate side support portion 44 is positioned at the front end of the rectifier plate 3 and engages with the hood side support portion 45. The rectifier plate side support portion 44 comprises a rectifier plate vertical portion 10 and a rectifier plate projection portion 9. The rectifier plate side support portion 44 is fixed to the rectifier plate 3 using fixing members such as screws or rivets (not shown).

[0033] The vertical section 10 of the rectifier plate is positioned vertically upward from the rectifier plate 3.

[0034] The rectifier plate projection 9 is erected from the rectifier plate vertical portion 10 toward the rear of the range hood 1.

[0035] The rectifier plate projection 9 is equipped with a claw portion 11 that stands vertically downward at its rear end.

[0036] The hood-side support portion 45 is positioned at the front end of the range hood 1 and engages with the rectifier plate-side support portion 44. The hood-side support portion 45 is fixed to the underside of the hood 7 using fastening materials such as screws. The hood-side support portion 45 includes a hood vertical portion 14 and a hood protruding portion 13.

[0037] The hood vertical section 14 rises vertically downward from the hood lower surface 7. The hood projection section 13 is erected forward from the hood vertical section 14 and has a groove section 12 that is recessed vertically from the upper surface of the hood projection section 13.

[0038] The hood-side support portion 45 is equipped with a permanent magnet as the magnetic portion 15.

[0039] The magnet section 15 is a component having a hard magnetic material such as a ferrite magnet or a neodymium magnet. The magnetic force of the magnet section 15 can attract the rectifier plate side support section 44, which is formed by processing a metal material having a magnetic material. The hood projection 13 encloses the magnet section 15 in the vicinity of the front surface 13a of the hood projection 13.

[0040] Next, the locking state of the front locking part 5 will be described in detail.

[0041] The magnetic force of the magnet section 15 causes the rear surface 10a of the vertical portion 10 of the rectifier plate on the rectifier plate side support section 44 to magnetically attach to the front surface 13a of the hood projection 13 of the hood side support section 45. This holds the lower surface of the rectifier plate projection 9 against the upper surface of the hood projection 13, thereby restricting vertical and horizontal movement. The claw portion 11 of the rectifier plate side support section 44 is inserted into the groove portion 12 of the hood projection 13, restricting the horizontal movement of the rectifier plate 3, and the front locking portion 5 becomes locked.

[0042] The front recess 16 is a space formed in the groove 12 that faces forward. In other words, the front recess 16 can be described as the gap between the claw portion 11 and the hood projection 13 that is created when the claw portion 11 enters the groove 12.

[0043] The claw portion 11 is inclined so that its lower end fits into the front recess 16.

[0044] Figure 6 shows a perspective view of the rectifier plate side support section 44.

[0045] Figure 7 shows a perspective view and a cross-sectional view of the hood-side support portion 45.

[0046] Next, the configuration of the rear locking section 6 will be explained using Figure 8. The rear locking section 6 is equipped with a pole section 47 on the hood 2 side and a hook section 46 on the rectifier plate 3 side.

[0047] The pole portion 47 is positioned at the rear end of the hood 2 and engages with the hook portion 46. The pole portion 47 comprises two vertical rods 22 that stand upright downwards from the hood 2 and a horizontal rod 23 connecting the two vertical rods 22.

[0048] The hook portion 46 is positioned at the rear end of the rectifier plate 3 and engages with the pole portion 47. The hook portion 46 comprises a connecting plate 17, a first horizontal plate 18, a first vertical plate 19, a second horizontal plate 20, and an arc portion 21.

[0049] The connecting plate 17 is fixed to the rectifier plate 3 using fastening members such as screws or rivets (not shown). The connecting plate 17 stands upright from the upper surface of the rectifier plate 3.

[0050] The first horizontal plate 18 protrudes from the upper end of the connecting plate 17 toward the rear of the connecting plate 17.

[0051] The first vertical plate 19 extends upward from the rear end of the first horizontal plate 18.

[0052] The second horizontal plate 20 extends from the upper end of the first vertical plate 19 toward the front arc portion 21.

[0053] The arc portion 21 extends downward from the front end of the second horizontal plate 20. The arc portion 21 has an arc shape that bulges forward toward the front of the second horizontal plate 20. In this configuration, a gap 31 is formed between the arc portion 21 and the first horizontal plate 18.

[0054] Figure 9 shows a perspective view of the hook portion 46.

[0055] Figure 10 shows a perspective view of the pole section 47.

[0056] Next, the locking state of the rear locking portion 6 will be described in detail. The rear locking portion 6 is engaged when the pole portion 47 engages with the second horizontal plate 20. When the front locking portion 5 is locked, the horizontal rod 23 is positioned on the inner circumference of the arc portion 21, restricting the vertical and rearward movement of the rectifier plate 3.

[0057] Next, the procedure for attaching and detaching the rectifier plate 3 to the hood 2 will be described. By engaging the hook portion 46 on the rectifier plate 3 with the pole portion 47 on the hood 2, the rear locking portion 6 is locked, and the range hood 1 takes on the appearance shown in Figure 2. At this time, the front locking portion 5 is released, and the rectifier plate 3 is rotatable around the point where the pole portion 47 is engaged with the second horizontal plate 20 at the rear locking portion 6.

[0058] As the rectifier plate 3 is rotated and lifted, the magnetic force of the magnet portion 15 embedded near the front surface 13a of the hood projection 13 of the hood-side support portion 45 attracts the rear surface 10a of the vertical rectifier plate portion 10 of the rectifier plate-side support portion 44, causing the rear surface 10a to magnetically attach to the front surface 13a of the hood projection 13 of the hood-side support portion 45. At this time, the rectifier plate 3 is parallel to the lower surface 7 of the hood. Next, by moving the rectifier plate 3 vertically downward relative to the hood 2, the upper surface of the hood projection 13 of the hood-side support portion 45 and the lower surface of the rectifier plate projection 9 of the rectifier plate-side support portion 44 come into contact. At this time, the front locking portion 5 is locked. The claw portion 11 of the rectifier plate-side support portion 44 is engaged with the front recess 16 of the hood-side support portion 45, restricting the horizontal movement of the rectifier plate 3. Furthermore, when the front locking part 5 is locked, the horizontal rod 23 of the pole part 47 of the rear locking part 6 is positioned on the inner circumference of the arc part 21 of the hook part, restricting the vertical movement of the rectifier plate 3 in the up-and-down direction and to the rear. When the front locking part 5 and the rear locking part 6 are locked, the range hood 1 will have the appearance shown in Figure 1.

[0059] The above describes the procedure for attaching the rectifier plate 3 to the hood 2. Next, we will explain the procedure for removing the rectifier plate 3 from the hood 2.

[0060] To remove the rectifier plate 3 from the state shown in Figure 1, the rectifier plate 3 is moved vertically upward relative to the hood. At this time, the claw portion 11 of the rectifier plate side support portion 44 is released from the state in which it was engaged with the front recess 16 of the hood side support portion 45.

[0061] Next, the rectifier plate 3 is moved horizontally forward relative to the hood 2. At this time, the magnetic attachment between the rear surface 10a of the vertical portion 10 of the rectifier plate on the rectifier plate side support portion 44 and the front surface 13a of the hood projection portion 13 on the hood side support portion 45 is released. The front locking portion 5 then becomes released. With the front locking portion 5 released, the rear locking portion 6 locks the rectifier plate 3 in a rotatable state.

[0062] Next, move the front side of the rectifier plate 3 slightly downwards.

[0063] Next, by moving the rectifier plate 3 horizontally forward relative to the hood 2, the horizontal rod 23 of the pole portion 47 of the rear locking portion 6 is released from being positioned on the inner circumference of the arc portion of the hook portion 46.

[0064] Next, the rear side of the rectifier plate 3 is moved slightly vertically upward. At this time, the horizontal rod 23 of the pole portion 47 of the rear locking portion 6 is positioned in the gap 31 of the hook portion 46.

[0065] Next, by moving the rectifier plate 3 backward relative to the hood 2, the rear locking part 6 is released, and the rectifier plate 3 can be removed from the hood 2.

[0066] The above is the procedure for removing the rectifier plate 3 from the hood 2.

[0067] The range hood 1 not only has a magnetic section 15 that attracts the hood 2 and the rectifier plate 3 by magnetic force, but also locks into place when the upper surface of the hood projection 13 of the hood-side support section 45 provided on the hood 2 comes into contact with the lower surface of the rectifier plate projection 9 of the rectifier plate-side support section 44 provided on the rectifier plate 3. Therefore, by making it easy and reliable to hook the rectifier plate-side support section 44 provided in front of the rectifier plate 3 onto the hood-side support section 45 provided in front of the hood 2, the range hood 1 can be provided that prevents the rectifier plate 3 from falling.

[0068] The following provides further details about this embodiment.

[0069] The range hood 1 according to the present invention comprises a hood 2 that draws in air from below, a rectifier plate 3 attached to the lower part of the hood 2, and a front locking part 5 that has a hood-side support part 45 provided on the hood 2 and a rectifier plate-side support part 44 provided on the rectifier plate 3, and locks the rectifier plate 3 to the hood on the front side of the hood 2, wherein the front locking part 5 is locked by locking the rectifier plate-side support part 44 to the hood-side support part 45 via the horizontal movement of the rectifier plate 3 from front to rear, and the hood-side support part 45 is equipped with a magnet part 15 that pulls the rectifier plate-side support part 44 from front to rear.

[0070] This makes it easy and reliable to hook the rectifier plate-side support part 44, which is located in front of the rectifier plate 3, onto the hood-side support part 45, which is located in front of the hood 2, thereby providing a range hood 1 that prevents the rectifier plate 3 from falling.

[0071] Furthermore, the magnet section 15 may have a horizontal magnetic force that pulls the rectifier plate side support section 44 horizontally and a vertical magnetic force that pulls the rectifier plate 3 vertically upward, and this vertical magnetic force may be configured to be smaller than the force that causes the rectifier plate 3 to fall vertically downward due to its own weight.

[0072] This allows the rectifier plate side support portion 44 to move vertically from the hood side support portion 45, making it easier to attach and detach the rectifier plate 3.

[0073] Furthermore, the configuration may be such that the horizontal magnetic force of the magnet section 15 is greater than the vertical magnetic force of the magnet section 15.

[0074] As a result, the rectifier plate side support portion 44 is more firmly magnetically attached to the hood protrusion portion 13 (especially the front surface 13a) of the hood side support portion 45, which prevents the rectifier plate side support portion 44 from separating from the hood side support portion 45 and makes it easier to attach and detach the rectifier plate 3.

[0075] Furthermore, the hood-side support portion 45 includes a hood vertical portion 14 that rises vertically downward from the hood 2 and a hood projection portion 13 that rises forward from the hood vertical portion 14, the rectifier plate-side support portion 44 includes a rectifier plate vertical portion 10 that rises vertically upward from the rectifier plate 3 and a rectifier plate projection portion 9 that rises rearward from the rectifier plate vertical portion 10, the magnet portion 15 is provided on the hood projection portion 13, and the front locking portion 5 may be configured such that the rear surface 10a of the rectifier plate vertical portion 10 is magnetically attached to the front surface 13a of the hood projection portion 13 by the magnetic force of the magnet portion 15, and the lower surface of the rectifier plate projection portion 9 is held by the upper surface of the hood projection portion 13, thereby locking in the vertical and horizontal directions.

[0076] As a result, the rectifier plate side support portion 44 can be held on the upper surface of the hood projection portion 13, so even if the rear surface 10a of the vertical portion 10 of the rectifier plate 10 becomes detached from the front surface 13a of the hood projection portion 13, the rectifier plate 3 will not fall.

[0077] Alternatively, the magnet portion 15 may be configured to be exposed on the front surface 13a of the hood projection portion 13.

[0078] As a result, the rear surface 10a of the vertical section 10 of the rectifier plate is directly magnetically attached to the magnet section 15, allowing the hood-side support section 45 to hold the rectifier plate-side support section 44 more firmly.

[0079] Alternatively, the magnet portion 15 may be configured to be embedded in the vicinity of the front surface 13a of the hood projection portion 13.

[0080] This allows for flexibility in the shape of the hood projection 13 and the front surface 13a, so that the hood-side support portion 44 of various shapes can be held by the hood-side support portion.

[0081] Furthermore, the hood projection 13 may be provided with a groove 12 that is recessed vertically from the upper surface, and the rectifier plate projection 9 may be provided with a claw portion 11 that is erected vertically downward at its rear end, and the claw portion 11 may be inserted into the groove 12 to restrict the horizontal movement of the rectifier plate 3.

[0082] This restricts the horizontal movement of the rectifier plate 3, thus preventing it from falling even if an impact is applied and a horizontal force is exerted on it.

[0083] Furthermore, the hood projection 13 may be configured to include a forward recess 16, which is a space formed in the groove 12 toward the front, and the claw portion 11 may be configured to stand vertically downward and have its lower end inclined to fit into the forward recess 16.

[0084] As a result, when engaged, the claw portion 11 is inserted into the front recess 16, thereby restricting the horizontal movement of the rectifier plate 3. Therefore, even if an impact is applied to the rectifier plate 3 and a horizontal force is acted upon it, the effect of suppressing the rectifier plate 3 from falling can be further enhanced.

[0085] Furthermore, the rear side of the hood 2 may be provided with a rear locking part 6 that locks the rectifier plate 3 to the hood 2, and the rear locking part 6 may be configured to lock the rectifier plate 3 so that it does not fall off the hood 2 when the locking state of the front locking part 5 is released.

[0086] As a result, even if the locking state of the front locking part 5 is released, the rectifier plate 3 will not fall, further enhancing the effect of suppressing the falling of the rectifier plate 3.

[0087] Furthermore, the rear locking section 6 comprises a pole section 47 having two vertical rods 22 that are provided on the hood 2 and stand upright toward the bottom of the range hood 1, and a horizontal rod 23 connecting the two vertical rods 22, and a hook section 46 provided on the rectifier plate 3. The hook section 46 comprises a connecting plate 17 that stands upright toward the top of the upper surface of the rectifier plate 3, a first horizontal plate 18 that protrudes toward the rear from the upper end of the connecting plate 17, a first vertical plate 19 that extends toward the top from the rear end of the first horizontal plate 18, and a second horizontal plate 20 that extends toward the front from the upper end of the first vertical plate 19, and the second horizontal The rear locking portion 6 may be configured such that, when the front locking portion 5 is locked, the horizontal rod 23 is positioned on the inner circumference of the arc portion 21, restricting the vertical movement of the rectifier plate 3 in the vertical direction and backward, and when the front locking portion 5 is released, the horizontal rod 23 is positioned in the gap 31, restricting the vertical movement of the rectifier plate 3 in the vertical direction and forward, while allowing the rectifier plate to move vertically downward and backward.

[0088] As a result, even if the locking state of the front locking part 5 is released, the locking state of the rear locking part 6 continues, further enhancing the effect of suppressing the falling of the rectifier plate 3.

[0089] Alternatively, the front locking portion 5 may be configured such that at least one is provided on the left side of the center of the hood 2 and at least one on the right side of the center when viewed from the front.

[0090] This allows for the installation of two or more front locking parts 5 on the left and right sides of the center of the hood 2 when viewed from the front, thus preventing the rectifier plate 3 from falling, regardless of its shape or size.

[0091] Furthermore, the rear locking portion 6 may be configured such that, when viewed from the front, at least one is provided on the left side of the center of the hood 2 and at least one on the right side of the center.

[0092] This allows for the installation of two or more rear locking parts 6 on the left and right sides of the center of the hood 2 when viewed from the front, thus preventing the rectifier plate 3 from falling, regardless of its shape or size.

[0093] Although the range hood according to the present invention has been described above based on embodiments, the present invention is not limited to these embodiments. Various modifications that a person skilled in the art could conceive of, as long as they do not depart from the spirit of the present invention, and forms constructed by combining components from different embodiments are also included within the scope of the present invention. [Industrial applicability]

[0094] The range hood according to the present invention is useful as a ventilation device installed above a cooking appliance or the like, as it is capable of suppressing the fall of the rectifier plate. [Explanation of Symbols]
