Description
[Technical field]
[0001] The present invention relates to a range hood. [Background technology]
[0002] Range hoods are provided with a removable air straightening plate on the underside of the hood to increase the efficiency of suctioning oily smoke generated during cooking. Oily smoke passes through the gap between the oil panel and air straightening plate on the underside of the hood and is sucked into the suction port, causing oil to adhere to the oil panel and air straightening plate. For this reason, the oil panel and air straightening plate on the underside of the hood must be cleaned periodically, and the oil panel and air straightening plate are cleaned by opening one end of the air straightening plate by supporting it at one end on the hood part, or by removing the air straightening plate from the hood part. To facilitate periodic cleaning, it is required that the air straightening plate be easily opened and removed, and that safety be guaranteed so that it does not open or fall accidentally.
[0003] As a range hood equipped with such an opening and detaching mechanism for the straightening plate, for example, a magnetic type opening and detaching mechanism for the straightening plate is proposed in Patent Document 1. Specifically, the inner panel of the hood is formed smoothly and partly made of a magnetic material, a magnetic part is formed on the tip side of the straightening plate, and the magnetic part on the straightening plate side and the magnetic material on the inner side of the hood are magnetically attached by rotating the straightening plate around the base end of the rear end of the straightening plate as an axis. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2018-115825 A Summary of the Invention [Problem to be solved by the invention]
[0005] The opening and detaching mechanism of the straightening plate in Patent Document 1 uses a magnet to easily open the straightening plate, and also has a damper mechanism at the base end to prevent the plate from opening forcefully even if the plate is unintentionally released. However, such a damper mechanism may no longer function as intended due to deterioration over time. Range hoods are products with a relatively long product life, and safety must be guaranteed throughout the product life.
[0006] Therefore, an object of the present invention is to provide a range hood that can ensure safety over the long term and has a baffle plate that can be easily opened and attached / detached. [Means for solving the problem]
[0007] In order to solve the above problem, the present invention provides a hood portion 20 having an opening for sucking in air, a straightening plate 40 that forms a suction gap between the hood portion 20 and the straightening plate 40, and a magnetic fastening plate that magnetically fastens the hood portion 20. The magnetic part 53 is provided for A first locking member 50; a second locking member 60 having a base 64 against which the magnetic portion 53 abuts and a fixed locking portion 61, the magnetic portion 53 abuts against the base 64, whereby the straightening plate 40 is magnetically locked to the hood portion 20, and the fixed locking portion 61 fixedly locks the straightening plate 40 and the hood portion 20 in this magnetically locked state, the second locking member 60 has a fixed piece 63 having a raised surface that hides at least a part of the first locking member 50 when viewed from the horizontal direction of the hood portion 20 in the state in which the straightening plate 40 and the hood portion 20 are magnetically locked, and the fixed piece 63 is provided horizontally outboard of the first locking member 50; One range hood is provided. This results in a two-stage locking structure in which the hood section 20 and the straightening plate 40 are magnetically locked by the first locking member 50 and then locked by the second locking member 60. The fixed locking ensures safety over the long term, and the magnetic attachment of the first locking member 50 allows temporary fixing before the fixed locking, so a range hood can be provided that allows the straightening plate 40 to be easily opened, attached, and detached even when using both hands or tools for the fixed locking.
[0008] Furthermore, the second fastening member 60 may be characterized in that it is composed of a fixed piece 63 and a base 64, and the fixed piece 63 to which the fixed fastening portion (panel fastener 61) is fixed is detachably provided on the base 64. According to this, replacement of the component becomes easy because the fixed piece 63 is provided detachably with respect to the base 64. If the fixed locking portion 61 is fixed (crimped) to the second locking member 60, it is necessary to replace the entire second locking member 60 in the event of a defect in the fixed locking portion 61. However, in the present invention, it is only necessary to replace the fixed piece 63, which is excellent in workability.
[0009] Furthermore, when the straightening plate 40 and the hood portion 20 are magnetically engaged, the receiving portion 64a formed on the top surface of the base 64 against which the magnetic portion 53 abuts may be characterized as being located at a higher position than the bottom surface of the straightening plate 40. According to this, the first locking member 50 abuts against the magnetized portion (base 64) instead of directly abutting against the straightening plate 40. When the first locking member 50 abuts against the straightening plate 40, there is a risk that the magnetization effect will be hindered by oil pools, but by abutting against the magnetized portion (base 64) where oil pools are less likely to form, the desired magnetization effect can be obtained.
[0010] Furthermore, the first locking member 50 may be characterized in that it is composed of a columnar locking portion 51, an insertion hole 52 formed in a direction intersecting the longitudinal direction of the columnar locking portion 51 and through which the insertion shaft 61a of the fixed locking portion (panel fastener 61) is inserted, and a magnetic portion (magnet 53) formed at the tip of the columnar locking portion 51. According to this, the straightening plate 40 is provisionally secured to the hood portion 20 by the magnetic attraction of the magnetic attraction portion (magnet 53), while the insertion shaft 61a of the fixed locking portion (panel fastener 61) is inserted into the insertion hole 52, thereby making it possible to maintain the locked state with a simple configuration. Also, since the insertion hole 52 is formed in a direction intersecting with the longitudinal direction of the columnar locking portion 51, that is, the attachment / detachment direction of the straightening plate 40 intersects (is perpendicular to) with the hole direction of the insertion hole 52, the locked state of the straightening plate 40 can be maintained with sufficient strength even at the stage of provisional insertion where the insertion shaft 61a is not yet fully inserted.
[0011] Furthermore, the casing 61c may be provided with a drop-out prevention piece 61d for preventing the insertion shaft 61a from dropping out. This prevents the insertion shaft 61a from falling off. Since the range hood 1 is installed at a high place in the kitchen, attaching and detaching the baffle plate 40 requires reaching overhead, making it difficult to check what is in front of you. In particular, when using tools, there is a concern that parts may fall off. In the present invention, the casing is provided with a fall prevention piece 61d that prevents the insertion shaft 61a from falling off, so the insertion shaft 61a will not fall off the casing 61c, and workability is excellent.
[0012] Furthermore, the device may be equipped with an engagement detection means (proximity sensor 44) for detecting engagement or non-engagement between the hood portion 20 and the straightening plate 40, an insertion detection unit 70 for detecting the insertion state of the insertion shaft 61a into the insertion hole 52, and an error notification means (error notification unit 82) for issuing a predetermined error notification, wherein the error notification means (error notification unit 82) issues a predetermined error notification when the engagement detection means (proximity sensor 44) detects that the engagement is present and the insertion detection unit 70 detects that the insertion state does not satisfy predetermined conditions. According to this, if the second locking member 60 is not sufficiently fixed and locked, a specified error notification is issued, so that the user can immediately detect the condition. Effect of the Invention
[0013] As described above, according to the present invention, it is possible to provide a range hood that can ensure safety over the long term and that allows the baffle plate to be easily opened, attached, and detached. [Brief description of the drawings]

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0016] The present invention is not limited to the illustrated examples, and may be implemented in any configuration that does not deviate from the scope of the claims. That is, the present invention has been particularly illustrated and described mainly with respect to specific embodiments, but those skilled in the art may make various modifications to the above-described embodiments in terms of the number and other details of the configuration without departing from the scope of the technical idea and purpose of the present invention.
[0017] <First Example> Hereinafter, the configuration of a range hood 1 according to an embodiment of the present invention will be described with reference to Figs. 1 to 9.

Fig. 8 is a partially enlarged cross-sectional view of a front locking mechanism 41a according to a second embodiment. Fig. 9 is a block diagram of a range hood 1 according to a second embodiment.
[0018] 1, for convenience, the left-right direction of the range hood 1 will be referred to as the X direction, the depth direction of the range hood 1 as the Y direction, and the vertical direction of the range hood 1 as the Z direction. Additionally, the left direction of the range hood 1 will be referred to as the negative X direction, the right direction as the positive X direction, the depth side of the range hood 1 as the positive Y direction, the front side as the negative Y direction, the upward direction of the range hood 1 as the positive Z direction, and the downward direction as the negative Z direction.
[0019] The basic structure of the range hood 1 will be described with reference to Fig. 1. The range hood 1 is installed above a cooking appliance (not shown) and is configured to suck in oily smoke, gas, etc. generated during cooking and exhaust it to the outside of the room. The range hood 1 includes a main body 4 that houses a fan casing (not shown), a hood 2 arranged at the bottom of the main body 4, an oil panel 30 arranged on the underside of the hood 2, and a straightening plate 40 arranged below the oil panel 30 and detachably attached to the hood 2 by a locking part 41. The locking part 41 is composed of a front locking mechanism 41a and a rear locking mechanism 41b, which will be described later. The hood 2 and the oil panel 30 constitute the hood part 20 of this embodiment.
[0020] The basic configuration of the hood 2 and the straightening plate 40 will be described with reference to Figs. 2 and 3. The hood 2 is formed thin and has a top surface, a side surface having an operation switch 81, and a bottom surface concave toward the cooking device. An oil panel 30 having an opening is attached to the bottom surface of the hood 2. The oil panel 30 has an outer edge formed along the inner edge of the bottom surface of the hood 2, and an inclined portion 30a inclined in the downstream direction of the air flow. An oil collecting member 7 is provided at the opening of the oil panel 30 to form an inlet for oily smoke. A rotary filter 5 is disposed downstream of the inlet, and the rotary filter 5 is rotated at high speed by a motor (not shown) to fly oil in the direction of the oil collecting member 7 and collect oil from the oily smoke passing through the inlet. The oil collecting member 7 is configured to be detachable from the oil panel 30 by operating the oil collecting member holder 7a, and the rotary filter 5 is also configured to be detachable by operating the one-touch unit 6.
[0021] The oil panel 30 is provided with a first locking member 50 on the front side (negative side in the Y direction) and a hanging bracket 32 on the rear side (positive side in the Y direction) as a mechanism for locking the straightening plate 40. The straightening plate 40 is provided with a second locking member 60 on the front side and a hook member 43 on the rear side so as to correspond to the mechanism of the oil panel 30. The first locking member 50 and the second locking member 60 constitute a front locking mechanism 41a, and the hanging bracket 32 and the hook member 43 constitute a rear locking mechanism 41b. The front locking mechanism 41a and the rear locking mechanism 41b constitute a locking portion 41 that locks the straightening plate 40 to the oil panel 30. The straightening plate 40 is also provided with a proximity sensor 44 as a locking detection means for detecting whether the straightening plate 40 and the oil panel 30 are in an engaged or non-engaged state. When the straightening plate 40 is engaged with the oil panel 30 as shown in FIG. 3, a gap 31 is formed between the straightening plate 40 and the oil panel 30, which increases the speed of air intake.
[0022] The configuration of the front locking mechanism 41a will be described with reference to FIG. 4. In this figure, the oil panel 30 to which the first locking member 50 is attached is omitted in order to make the member structure easier to understand. The first locking member 50 constituting one side of the front locking mechanism 41a is composed of a columnar locking portion 51 and a magnet 53 (magnetically attached portion) provided at the tip of the columnar locking portion 51. The columnar locking portion 51 is composed of a cylindrical body portion 51a and a tapered head portion 51b formed continuously with the body portion 51a, and an insertion hole 52 described later is provided in the body portion 51a. The magnet 53 (magnetically attached portion) is provided at the tip of the head portion 51b and is formed in a circular shape that is approximately the same as the horizontal cross-sectional shape of the tip of the head portion 51b.
[0023] The second locking member 60 constituting the other of the front locking mechanism 41a is composed of a pedestal 64 (a magnetized portion) having a hat-shaped cross section in the Y direction, a fixed piece 63 fixed to the pedestal 64 (a magnetized portion), and a panel fastener 61 (fixed locking portion) provided on the fixed piece 63. The pedestal 64 (a magnetized portion) is a box-shaped member having a hat-shaped cross section, and a brim portion having a hat-shaped cross section is fixed to the straightening plate 40. The pedestal 64 (a magnetized portion) has an opening in the direction of the gap 31 (the positive side in the X direction), and the top surface portion functions as a receiving portion 64a for the magnet 53 (a magnetized portion) of the first locking member 50. The fixed piece 63 is formed in a substantially L-shape (a substantially inverted L-shape in cross section) in the X direction cross section, and has a bottom surface 63a that is inserted into the opening of the pedestal 64 (a magnetized portion) and joined by a rivet or the like, and a rising surface 63b that rises from the bottom surface 63a to the positive side in the Z direction. A fixed engaging portion (panel fastener 61) is crimped to the rising surface 63b at a position corresponding to the hole. When a defect occurs in the fixed engaging portion (panel fastener 61) and it needs to be replaced, it can be replaced simply by releasing the connection between the base 64 (magnetically attracted portion) and the fixed piece 63 with a rivet removal jig or the like. Note that, in this embodiment, the magnet 53 (magnetically attracted portion), which is a magnetic material, is formed on the first engaging member 50 on the oil panel 30 side, but the base 64 (magnetically attracted portion) side may also be made of a magnetic material and magnetically attracted.
[0024] The locking configuration of the front locking mechanism 41 will be described with reference to Figures 5 and 6. Figure 5 is a cross-sectional view of a state in which the magnet 53 (magnetic part) of the first locking member 50 abuts against the base 64 (magnetically attracted part) of the second locking member 60, and the straightening plate 40 is temporarily fixed to the oil panel 30, and Figure 6 is a partially enlarged cross-sectional view of the front locking mechanism 41 located on the right side when viewed from the front of the range hood. The panel fastener 61 (fixed locking part) is composed of an insertion shaft 61a, a shaft head 61b, and a casing 61c that houses the insertion shaft 61a, and the casing 61c is provided with a drop-out prevention piece 61d that prevents the shaft head 61b from falling off. The shaft head 61b is screwed and fixed in the direction of the insertion hole 52, so that the front locking mechanism 41 is in a fixed and locked state.
[0025] The insertion hole 52 formed in the body 51a of the columnar locking part 51 is formed in a direction intersecting with the longitudinal direction of the columnar locking part 51. That is, the insertion shaft 61a is configured to be inserted in the X direction, and the insertion shaft is fixed and locked by screwing it in using a tool or the like. Also, the height from the bottom surface of the base 64 (the part to be magnetized) to the receiving part 64a is configured to be the same height L1 as the outer peripheral rising edge part 40a of the straightening plate. Therefore, the magnet does not come into contact with the oil pool that is likely to occur on the straightening plate 40. Also, the region L2 of the head 51b forming the tapered surface of the columnar locking part 51 is formed from a position corresponding to the lower end surface 2a of the hood 2 in the cross-sectional view of FIG. 5. This reduces the resistance of the suction flow caused by the columnar locking part 51.
[0026] <Installation process of the airflow plate 40> Fig. 7 is a diagram showing the process of attaching the straightening plate 40. The process from when the straightening plate 40 is removed to when it is attached will be described with reference to Figs. 7(A) to 7(D). The attachment process is performed in the order of Figs. 7(A) → 7(B) → 7(C) → 7(D) to lock and fix the plate, and the process of removing the plate from the locked and fixed state is performed in the reverse order to the attachment process. The attachment process of the straightening plate will be described below.
[0027] 7(A) shows a state in which the straightening plate 40 has been removed from the oil panel 30 and the range hood 1 and the straightening plate 40 are separated. To attach the straightening plate 40 to the oil panel 30, first, the straightening plate 40 is moved in the direction of the arrow to hook the hook member 43 of the rear locking mechanism 41b onto the hanging metal fitting of the oil panel 30, and the rear locking mechanism 41b is in a cantilever locked state.
[0028] 7(B), the rear locking mechanism 41b locks the straightening plate 40 in a cantilevered state with respect to the oil panel 30. By holding the front side of the straightening plate 40 with the left and right hands from the cantilevered state and pushing it up in the direction of the arrow, the second locking member 60 constituting the front locking mechanism 41a is moved closer to the first locking member 50 to a position where each locking member can be locked.
[0029] 7(C), the rear locking mechanism 41b and the front locking mechanism 41a have moved to positions where they can be locked, and the baffle plate 40 is provisionally locked to the oil panel 30. In this state, the base 64 (magnetically attracted portion) of the second locking member 60 constituting the front locking mechanism 41a and the magnet 53 (magnetic portion) of the first locking member 50 are in contact with each other and are magnetically attracted to each other. In this magnetically attracted state, the provisionally locked state is maintained even if the baffle plate 40 is not pressed by hand.
[0030] 7(D) shows a procedure for changing the state of the straightening plate 40 and the oil panel 30 from the provisionally locked state to the fixedly locked state. First, in the provisionally locked state, the insertion shaft 61a of the fixed locking portion (panel fastener 61) of the second locking member 60 is inserted into the insertion hole formed in the columnar locking portion 51 of the first locking member 50. In the provisionally locked state, it is possible to release the hands from the straightening plate 40 and work on the fixed locking portion (panel fastener 61) one by one on the left and right sides, or to temporarily fasten the fixed locking portion (panel fastener 61) while holding the front locking mechanism 41a with both hands. Next, the fixed locking portion (panel fastener 61) is fully fastened using a tool to fix the straightening plate 40 to the oil panel 30.
[0031] The straightening plate 40 is attached to the oil panel 30 through the above-mentioned process. That is, the straightening plate 40 and the oil panel 30 are magnetically engaged as the first stage of engagement, and the straightening plate and the oil panel are fixed and engaged by the panel fastener 61 as the second stage of engagement. This makes it possible to provide a range hood that can ensure safety for a long period of time by the fixed engagement, and can perform temporary fixing before the fixed engagement by the magnetic attachment of the first engagement member 50, so that the straightening plate can be easily opened, attached, and detached even when using both hands or tools for the fixed engagement. In this embodiment, the rear side engagement mechanism 41b constituting the engagement part 41 is configured to rotate around the base end as an axis, but it is possible to appropriately change within the scope of the present invention to arrange the magnetic engagement by the front side engagement mechanism 41a on the rear side to provide three-point support, four-point support, or the like. In this embodiment, the straightening plate 40 is attached to the oil panel 30, but it goes without saying that the straightening plate 40 may be directly attached to the hood 2 constituting the hood part 20.
[0032] <Second Example> The range hood 1 of this embodiment will be described with reference to Fig. 8. In order to avoid repetition, the same components are given the same reference numerals and their descriptions are omitted, and the following description will focus on the differences from the first embodiment. Fig. 8 is an enlarged cross-sectional view showing the locking configuration of the front locking mechanism 41 of the range hood 1 of this embodiment. The magnet 53 (magnetic portion) of the first locking member 50 abuts against the base 64 (magnetic portion) of the second locking member 60, and the straightening plate 40 is provisionally fixed to the oil panel 30.
[0033] The columnar locking portion 51 of the first locking member 50 has an insertion hole 52 formed in the X direction of the body 51a and a detection through hole 51c formed in the Z direction. The detection through hole 51c is configured as a through hole that penetrates from the base end of the body 51a of the columnar locking portion 51 to the tip of the head 51b. The detection through hole 51c is connected to the insertion hole 52 formed in the body 51a, and is configured so that the insertion shaft 61a of the fixed locking portion (panel fastener 61) that passes through the insertion hole 52 can appear and disappear.
[0034] Next, a portion where the base end of the body 51a of the columnar locking part 51 is installed will be described. The base end of the body 51a of the columnar locking part 51 is installed on the oil panel 30. A space S is formed between the oil panel 30 and the hood 2, and in this embodiment, the insertion detection part 70 is arranged in this space S. The insertion detection part 70 is composed of an insertion sensor 71 and an insertion sensor base 71a, and the insertion detection part 70 is configured to be able to transmit a detection signal to the range hood control part 100. The insertion sensor 71a of the insertion detection part 70 is composed of a photosensor and is provided at a position corresponding to the base end of the detection through hole 51c. As a result, the insertion detection part 70 is configured to be able to detect the insertion shaft 61a that appears and disappears in the detection through hole 51c. Note that the insertion sensor 71a is not limited to a photosensor, and may be any detection means capable of detecting the presence or absence of an object, such as a proximity sensor, a position sensor, a contact sensor, an image sensor, an ultrasonic sensor, a microwave sensor, an overcurrent type displacement sensor, or a CCD camera.
[0035] The control unit of the range hood 1 according to this embodiment will be described with reference to FIG. 9. The RH control unit 80 is provided inside the main body 4 and controls the operation of the fan and the rotary filter 5 based on signals from the operation switch 81, the proximity sensor 44, and the insertion detection unit 70. The RH control unit 80 is a microcontroller that stores a program for controlling the operation of the fan and the rotary filter 5 and executes commands according to the program. The operation switch 81 transmits an air volume switching signal when pressed. The proximity sensor 44 transmits a signal when the straightening vane 40 is separated from the oil panel 30. The RH control unit 80 receives this signal and stops the operation control of the fan and the rotary filter 5, and issues a command to the error notification unit 82 to issue an error notification. The error notification unit 82 receives this command and issues a predetermined error notification, for example, a notification indicating that an error has occurred using sound, light, video, or the like.
[0036] The insertion detection unit 70 detects the insertion shaft 61a appearing in and disappearing from the detection through hole 51c, and transmits a detection signal to the RH control unit 80. When the signal from the proximity sensor 44 does not indicate that the straightening plate 40 has been separated from the oil panel 30, and when the signal from the insertion detection unit 70 does not indicate that the insertion depth of the insertion shaft 61a has reached a predetermined position, the RH control unit 80 instructs the error notification unit 82 to issue an error notification. That is, when the straightening plate 40 is attached to the oil panel 30 and is not sufficiently fixed and locked by the fixing locking unit (panel fastener 61), an error notification is issued. By configuring in this manner, the user can immediately sense the state and can be prompted to perform sufficient fixing and locking. In this embodiment, the straightening plate 40 is attached to the oil panel 30, and there is no risk of fingers entering the fan, so the configuration is such that only an error notification is issued, but the configuration may be such that not only the error notification but also the operation control of the fan and the rotary filter 5 is stopped.
[0037] The present invention is not limited to the illustrated examples, and may be implemented in any configuration that does not deviate from the scope of the claims. That is, the present invention has been particularly illustrated and described mainly with respect to specific embodiments, but those skilled in the art may make various modifications to the above-described embodiments in terms of the number and other details of the configuration without departing from the scope of the technical idea and purpose of the present invention.
