Description

The present invention relates to a range hood.

Range hoods are equipped with a removable air straightening plate on the underside of the hood to improve 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 on one side of the hood, or by removing the air straightening plate from the hood. To facilitate periodic cleaning, it is required that the air straightening plate be easy to open and remove, and that safety be guaranteed so that it does not open or fall accidentally.

As an example of a range hood equipped with such a mechanism for opening and removing the straightening plate, Patent Document 1 proposes a magnetic mechanism for opening and removing the straightening plate. Specifically, the inner panel of the hood is formed smoothly and partly made of a magnetic material, and 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 to each other by rotating the straightening plate around the base end of the rear end of the straightening plate as an axis.

JP 2018-115825 A

The opening and detaching mechanism for the baffle plate in Patent Document 1 uses a magnetic lock to make it easy to open the baffle plate, and also has a damper mechanism at the base end to prevent it from opening forcefully even if the lock is released unintentionally. However, such a damper mechanism may deteriorate over time and no longer function as it should. Range hoods are products with a relatively long product lifespan, and safety must be guaranteed throughout that product lifespan.

The present invention aims to provide a range hood that can ensure safety over the long term and that allows the baffle plate to be easily opened and removed.

In order to solve the above problems, a range hood 1 is provided, which comprises a hood section 20 having an opening for drawing in air, a straightening plate 40 which forms an intake gap between the hood section 20, a first engaging member 50 having a magnetic portion 53 for magnetically engaging the straightening plate 40 and the hood section 20, and a second engaging member 60 having a base 64 against which the magnetic portion 53 abuts and a fixed engaging portion 61, wherein the straightening plate 40 is magnetically engaged to the hood section 20 when the magnetic portion 53 abuts against the base 64, and the fixed engaging portion 61 fixedly engages the straightening plate 40 and the hood section 20 in this magnetically engaged state, and the second engaging member 60 has a fixed piece 63 having a raised surface that hides at least a part of the first engaging member 50 when viewed from the horizontal direction of the hood section 20 in a state in which the straightening plate 40 and the hood section 20 are magnetically engaged, and the fixed piece 63 is provided horizontally outboard of the first engaging member 50 .
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 that a range hood can be provided that allows the straightening plate 40 to be easily opened, attached, and detached even when both hands or tools are used for the fixed locking.

Furthermore, the second locking 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 locking portion (panel fastener 61) is fixed is detachably provided on the base 64.
According to this, the fixing piece 63 is provided detachably with respect to the base 64, which facilitates replacement of the component. If the fixed locking portion 61 is fixed (crimped) to the second locking member 60, it would be 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 provides excellent workability.

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 occur, the desired magnetization effect can be obtained.

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 can be temporarily locked to the hood portion 20 by the magnetic attraction of the magnetic attraction portion (magnet 53), while the locked state can be maintained by a simple configuration in which the insertion shaft 61a of the fixed locking portion (panel fastener 61) is inserted into the insertion hole 52. In addition, 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 temporary insertion where the insertion shaft 61a is not fully inserted.

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, the installation and removal of the baffle plate 40 requires the worker to reach above his head, making it difficult to see what is in front of him. In particular, when the work is done 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 the workability is excellent.

Furthermore, the device may be equipped with an engagement detection means (proximity sensor 44) for detecting engagement or disengagement 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 engaged 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.

As explained above, the present invention can provide a range hood that can ensure safety over the long term and allows the baffle plate to be easily opened and removed.

Fig. 8 is a partially enlarged cross-sectional view of the front locking mechanism 41a according to the second embodiment. Fig. 9 is a block diagram of the range hood 1 according to the second embodiment.

In the following explanation, 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, as shown in Figure 1. In addition, the left direction of the range hood 1 will be referred to as the negative X side, the right direction as the positive X side, the depth side of the range hood 1 as the positive Y side, the front side as the negative Y side, the upward direction of the range hood 1 as the positive Z side, and the downward direction as the negative Z side.

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 oil smoke, gas, etc. generated during cooking and exhaust it to the outside. The range hood 1 comprises a main body 4 that houses a fan casing (not shown), a hood 2 that is disposed below the main body 4, an oil panel 30 that is disposed on the underside of the hood 2, and a baffle plate 40 that is disposed below the oil panel 30 and is detachably attached to the hood 2 by a locking portion 41. The locking portion 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 portion 20 of this embodiment.

The basic configuration of the hood 2 and the baffle plate 40 will be described with reference to Figures 2 and 3. The hood 2 is formed thin and has a top surface, a side surface with an operation switch 81, and a bottom surface that is concave toward the cooking machine. An oil panel 30 with an opening is attached to the bottom surface of the hood 2. The outer edge of the oil panel 30 is formed to follow the inner edge of the bottom surface of the hood 2, and an inclined portion 30a that inclines in the downstream direction of the air flow is formed. An oil collecting member 7 is provided at the opening of the oil panel 30, forming an inlet for oil smoke. A rotary filter 5 is disposed downstream of the inlet, and this rotary filter 5 rotates 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 oil smoke passing through the inlet. The oil collecting member 7 is configured to be freely attached and detached from the oil panel 30 by operating the oil collecting member holder 7a, and the rotary filter 5 is also configured to be freely attached and detached by operating the one-touch unit 6.

The oil panel 30 is provided with a first locking member 50 on the front side (negative Y-side) and a hanging bracket 32 on the rear side (positive Y-side) 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 to correspond to the mechanism of the oil panel 30. The first locking member 50 and the second locking member 60 constitute the front locking mechanism 41a, and the hanging bracket 32 and the hook member 43 constitute the rear locking mechanism 41b. The front locking mechanism 41a and the rear locking mechanism 41b constitute the 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 baffle plate 40 is engaged with the oil panel 30 as shown in FIG. 3, a gap 31 is formed between the baffle plate 40 and the oil panel 30, which increases the speed of air intake.

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, which constitutes one side of the front locking mechanism 41a, is composed of a columnar locking portion 51 and a magnet 53 (magnetic 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 the body portion 51a is provided with an insertion hole 52 described later. The magnet 53 (magnetic 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.

The second locking member 60, which constitutes the other of the front locking mechanism 41a, is composed of a base 64 (magnetic part) with a hat-shaped cross section in the Y direction, a fixed piece 63 fixed to the base 64 (magnetic part), and a panel fastener 61 (fixed locking part) provided on the fixed piece 63. The base 64 (magnetic part) is a box-shaped member with a hat-shaped cross section, and the hat-shaped flange is fixed to the straightening plate 40. The base 64 (magnetic part) has an opening in the direction of the gap 31 (positive side in the X direction), and the top surface functions as a receiving part 64a for the magnet 53 (magnetic part) of the first locking member 50. The fixed piece 63 is formed in an approximately L-shape (approximately 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 base 64 (magnetic part) and joined with 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. If a problem occurs with 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 tool or the like. 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.

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 the state in which the magnet 53 (magnetic portion) of the first locking member 50 abuts against the base 64 (magnetically attracted portion) of the second locking member 60, and the baffle plate 40 is temporarily fixed to the oil panel 30. 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 portion) 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 fall 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, thereby placing the front locking mechanism 41 in a fixed and locked state.

The insertion hole 52 formed in the body 51a of the columnar locking part 51 is formed in a direction intersecting the longitudinal direction of the columnar locking part 51. That is, the insertion shaft 61a is configured to be able 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. In addition, the height from the bottom surface of the base 64 (the magnetized part) 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. In addition, the region L2 of the head 51b that forms 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.

<Step of attaching the flow plate 40>
Figure 7 shows the installation process of the straightening plate 40. The process from when the straightening plate 40 is removed to when it is installed will be described with reference to Figures 7(A) to 7(D). The installation process is performed in the order of Figures 7(A) → 7(B) → 7(C) → 7(D) to lock and secure the plate, and the process of removing the plate from the locked and secured state is performed in the reverse order to the installation process. The installation process of the straightening plate will be described below.

In Figure 7 (A), the baffle plate 40 has been removed from the oil panel 30, and the range hood 1 and the baffle plate 40 are separated. To attach the baffle plate 40 to the oil panel 30, first move the baffle plate 40 in the direction of the arrow to hook the hook member 43 of the rear locking mechanism 41b onto the hanging hardware of the oil panel 30, and then the rear locking mechanism 41b is in a cantilevered locking state.

In Figure 7 (B), the baffle plate 40 is in a cantilevered state with respect to the oil panel 30 due to engagement with the rear engagement mechanism 41b. From the cantilevered state, the front of the baffle plate 40 is held with the left and right hands and pushed up in the direction of the arrow, moving the second engagement member 60 constituting the front engagement mechanism 41a closer to the first engagement member 50 and into a position where each engagement member can be engaged.

In Figure 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 attached 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 and magnetically attached. In this magnetically attached state, the provisionally locked state is maintained even if the baffle plate 40 is not held down by hand.

Figure 7 (D) shows the procedure for changing the state of the baffle plate 40 and the oil panel 30 from the provisionally locked state to the fixed 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 baffle plate 40 and work on the fixed locking portions (panel fastener 61) one at a time on the left and right sides, or to temporarily fasten the fixed locking portions (panel fastener 61) while holding the front locking mechanism 41a with both hands. Next, the fixed locking portions (panel fastener 61) are fully fastened using a tool to fix the baffle plate 40 to the oil panel 30.

Through the above steps, the straightening plate 40 is attached to the oil panel 30. 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 ensure safety over a long period of time through the fixed engagement, and since the magnetic attachment of the first engagement member 50 allows temporary fixing before the fixed engagement, it is possible to provide a range hood that allows the straightening plate to 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 portion 41 is configured to rotate around the base end as an axis, but it is also possible to appropriately modify 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, etc. In addition, in this embodiment, a form in which the straightening plate 40 is attached to the oil panel 30 has been described, but it goes without saying that the straightening plate 40 may be directly attached to the hood 2 constituting the hood portion 20.

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 denoted by the same reference numerals and their description is omitted, and the 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 (magnetically attached portion) of the second locking member 60, and the straightening plate 40 is provisionally fixed to the oil panel 30.

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. In addition, 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.

Next, the portion where the base end of the body 51a of the columnar locking portion 51 is installed will be described. The base end of the body 51a of the columnar locking portion 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 portion 70 is disposed in this space S. The insertion detection portion 70 is composed of an insertion sensor 71 and an insertion sensor base 71a, and the insertion detection portion 70 is configured to be able to transmit a detection signal to the range hood control portion 100. The insertion sensor 71a of the insertion detection portion 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 portion 70 is configured to be able to detect the insertion shaft 61a that appears and disappears in the detection through hole 51c. The insertion sensor 71a is not limited to being a photosensor, but may be any detection means capable of detecting the presence or absence of an object, such as a proximity sensor, position sensor, contact sensor, image sensor, ultrasonic sensor, microwave sensor, eddy current displacement sensor, or CCD camera.

With reference to FIG. 9, the control unit of the range hood 1 according to this embodiment will be described. 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 baffle plate 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 sound, light, video, or other notification indicating that an error has occurred.

The insertion detection unit 70 detects the insertion shaft 61a that appears and disappears in 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 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 commands the error notification unit 82 to issue an error notification. In other words, 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 way, 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 it may be configured to stop operation control of the fan and the rotating filter 5 in addition to issuing an error notification.

The present invention is not limited to the illustrated examples, but may be implemented in configurations that do not deviate from the contents of the claims. In other words, the present invention has been particularly illustrated and described primarily with respect to specific embodiments, but those skilled in the art may make various modifications to the above-described embodiments in terms of quantity and other detailed configurations without departing from the scope of the technical idea and purpose of the present invention.
