[0006] ,
[0001] The present invention relates to a range hood.
[0002] Conventionally, range hoods have been used in kitchens (Patent Document 1).
[0003] Japanese Patent Application Laid-Open No. 2005-16842
[0004] Many storage shelves and the like are attached to the kitchen, and it has been troublesome to install the range hood. The present invention aims to provide a range hood with good workability.
[0005] The present invention includes a suspension fitting and a cover that covers at least a part above the hood portion. The suspension fitting includes a fixing portion fixed to the wall surface and a pair of support bars extending forward from the left and right of the fixing portion. The support bar has a regulating portion that regulates the left and right positions of the side plate of the cover. The cover has a supported portion on the side plate that is attached by moving forward to backward along the support bar of the suspension fitting. The supported portion has a regulated portion whose position is regulated by the regulating portion, thereby solving the problem with a range hood.
[0006] By the present invention, the workability has been improved.

[0008] Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same reference numerals in different figures indicate parts with the same function, and redundant explanations in each figure will be omitted as appropriate.
[0009] In some cases, kitchen cabinets (storage shelves) are positioned so close to the space where the range hood 9 is to be installed. The installation procedure for the range hood 9 may involve installing it after the kitchen cabinets, resulting in the cabinets being positioned very close to the range hood 9. In such situations, there is no space to store tools, causing problems with the installation process.
[0010] The following examples attempt to solve this problem.
[0011] [Example 1] (Range Hood 9) Figure 1 is an explanatory diagram of the range hood 9. Figure 1(A) is a perspective view of the range hood 9. Figure 1(B) is an explanatory diagram of the main components related to Example 1. F represents the front, B represents the rear, L represents the left, and R represents the right. As shown in Figure 1(A), the range hood 9 of Example 1 has a main body with a blower fan installed inside, on top of the hood part 5, and the main body is covered by a main body cover 3. An exhaust duct connection part 4 is provided at the top of the main body, and the cover 1 (slide duct) covers a duct (not shown) that is connected to the exhaust duct connection part 4. In this example, the cover 1 (slide duct) covers a duct (not shown). (Only the upper end is visible in Figure 1(A).) However, the cover 1 of the present invention is a broad concept that also includes those that do not cover the duct. Cover 1 is a sliding duct, meaning it is installed by sliding it. By sliding cover 1 up and down relative to the main body cover 3 to adjust the overall height of the range hood 9 before installation, it can accommodate different ceiling heights depending on the installation location.
[0012] The hanging bracket 2 is equipped with a fixing part 23 (wall mounting part), and support bars 21 are provided extending forward from both the left and right ends of the fixing part 23. The fixing part 23 (wall mounting part) is provided with wall mounting screw holes 231, and the hanging bracket 2 is fixed to the wall by driving screws into them. The hanging bracket 2 is fixed to the wall in a location that is not obstructed by the kitchen cabinet (storage shelf) and can be easily installed. Note that the method of fixing the hanging bracket 2 to the wall is not limited to screwing, and any method that can hold the cover 1 is included.
[0013] The suspension bracket 2 has a pair of support bars 21 on the left and right sides. In contrast, the cover 1 has a pair of supported parts on the side plates 119 on the left and right sides. Each supported part has a flap 11, and the flap 11 has a horizontal plate 111 that is folded inward. As will be explained in more detail later, the supported parts provided on the cover 1 are inserted into the support bars 21 of the suspension bracket 2, thereby supporting the cover 1 by the support bars 21. The cover 1 is supported by the support bars 21 and mounted near the ceiling.
[0014] Cover 1 is primarily intended to conceal the duct and does not support the motor or other components of the range hood 9. The motor and other main components of the range hood 9 are supported by other means. The range hood 9 in this embodiment is a type in which the exhaust duct connection part 4 is mounted above the main body, but there are various types of range hoods 9. For example, there are range hoods 9 in which the exhaust duct connection part 4 is located on the side of the main body, and in addition to the exhaust duct (not shown), there is also a range hood 9 that has a supply duct, which is a duct that takes in outside air into the room. There are also range hoods 9 (circulating type) that do not discharge the air exhausted from the main body to the outside, but instead remove smoke, steam, oil fumes and odors and return it to the room. Even in such a circulating type range hood 9, the flow path connected to the circulation port for returning the air from the main body to the room corresponds to the duct as defined in this invention. This invention is applicable regardless of the position and direction of the exhaust duct connection part 4, or whether the purpose of the duct is exhaust or supply air, and even when cover 1 covers other components as well, it is referred to as cover 1 in this specification for convenience. The primary purpose of installing cover 1 is to give the range hood 9 a cleaner appearance, and it is no different from a typical cover in that it covers at least a portion of the area above the hood section 5.
[0015] (Steps for attaching the cover 1 to the hanging bracket 2) Figure 2 is an explanatory diagram of the steps for attaching the cover 1 to the hanging bracket 2. (Step 1) The attachment of the cover 1 begins with attaching the hanging bracket 2 to the wall. The fixing part 23 (wall mounting part) of the hanging bracket 2 is brought into contact with the wall and fastened with screws through the wall mounting screw holes 231. The cover 1 has a structure that encloses three sides other than the wall side and has a side plate 119 that covers the side side.
[0016] (Step 2) and (Step 3) The worker inserts the supported portion of the cover 1 onto the support bar 21 of the fixed suspension fitting 2. Insertion begins when the horizontal plate 111 connected to the flap 11 of the cover 1 slides into the support bar 21. In this embodiment, the flap 11 and the horizontal plate 111 together constitute the supported portion. Although embodiment 1 is described as "insertion," the present invention also includes embodiments other than insertion, as long as the supported portion consisting of the flap 11 and the horizontal plate 111 can be supported by the support bar 21.
[0017] (Step 4) When the supported portion of the cover 1 is inserted into the support bar 21, the support bar 21 is located inside the cover 1, so the support bar 21 gradually becomes invisible as the supported portion (11, 111) of the cover 1 is inserted.
[0018] (Guidance for the horizontal plate 111 (supported part) of cover 1) Figure 3 is an explanatory diagram showing how the horizontal plate 111 of the flap 11 provided on cover 1 is guided to the rail portion 212 (support portion) of the hanging bracket 2. Figure 3(A) is a perspective view of cover 1. Figure 3(B) is an enlarged view of the area within frame a attached to Figure 3(A). Figure 3(C) is an enlarged view of the hanging bracket 2. Figure 3(D) is an enlarged view of the support bar 21 as seen from the direction of the arrow attached to Figure 3(C). The flap 11 of cover 1 is connected to the horizontal plate 111 which is bent inward. The lower edge of the horizontal plate 111 (supported part) moves and is guided on the rail portion 212 (support portion) of the hanging bracket 2 shown in Figure 3(D). To ensure reliable guidance, the rail portion 212 (support portion) is surrounded by a front guide wall 2125 and a rear guide wall 2126. The rear guide wall 2126 is positioned to narrow towards the depth direction. The supported portion, which consists of the flap 11 and the side plate 111 of the cover 1 that move along the rail portion 212 (support portion), is guided to move towards the opposing wall 2127 as it moves further inward.
[0019] The opening, formed by the front guide wall 2125 and the opposing wall 2127, is wide open, making it easy to insert the flap 11 and the horizontal plate 111 (supported part) of the cover 1. The flap 11 and the horizontal plate 111 (supported part) of the cover 1 also have an inclined portion 1111 that shortens in height toward the wall side (rear). This makes it easier to align the cover 1 when inserting it toward the support bar 21 of the hanging bracket 2 installed near the ceiling. Furthermore, by inserting the cover 1 while bringing the inclined portion 1111 into contact with the front end portion of the lower surface of the support bar 21 (the front end portion of the rail portion 212 (support part) in the illustrated example), the vertical position of the cover 1 is automatically determined, making alignment work easier and reducing the risk of damaging the ceiling during installation.
[0020] (Restricted portion and restricted portion) As shown in Figure 3(B), the lower end of the horizontal plate 111 on the cover 1 is provided with a first restricted portion 112 (step) and a second restricted portion 113 (step).
[0021] (Ceiling flap 2128 and rail section 212 (support section)) The support bar 21 of the hanging bracket 2 has a rail section 212 (support section) and a ceiling flap 2128. The left-right width of the ceiling flap 2128 is narrower than the left-right width of the rail section 212 (support section). This reduces the risk of the cover 1 coming into contact with the ceiling and damaging it during installation when inserting the cover 1 towards the support bar 21 of the hanging bracket 2 installed near the ceiling, and also improves the visibility of the rail section 212 (support section), making it easier to align.
[0022] Figure 5 is an explanatory diagram of the restricting portion provided on the support bar 21 of the suspension fitting 2. The support bar 21 has a first restricting portion 2121 (groove-shaped) and a second restricting portion 2123 (groove-shaped). The position is restricted when the first restricted portion 112 (step) on the cover side engages with the first restricting portion 2121 (groove-shaped) on the suspension fitting 2 side, and when the second restricted portion 113 (step) on the cover side engages with the second restricting portion 2123 (groove-shaped) on the suspension fitting side. Through this engagement, the left-right and front-back positions of the cover 1 and the support bar 21 are restricted without the need for a complex mechanism. The first restricted portion 112 (step) and the second restricted portion 113 (step) are inclined to facilitate engagement with the first restricting portion 2121 (groove-shaped) and the second restricting portion 2123 (groove-shaped), respectively.
[0023] (First regulated section 112 and second regulated section 113)
[0024] The first restricted portion 112 and the second restricted portion 113 may be inclined or perpendicular (rectangular) when they are considered as steps.
[0025] Figure 4 is an explanatory diagram of the first restricted portion 112 and the second restricted portion 113. Furthermore, if the first restricted portion 112 and the second restricted portion 113 are stepped, the height of the step in the second restricted portion 113 may be lower than the plate thickness of the hanging bracket 2. Also, if the first restricted portion 112 and the second restricted portion 113 are stepped, the portion between the first restricted portion 112 and the second restricted portion 113, that is, the portion of the lower end of the horizontal plate 111 that contacts the rail portion 212 of the hanging bracket 2 when installed, may be inclined upward toward the wall. In this embodiment 1, as a preferred example, the height direction length of the horizontal plate 111 at point A in the figure and the height direction length at point B in the figure are such that point A > point B. In this configuration, when installed, the rear side of the cover 1 (the wall side in Figure 4) moves downward and the front side of the cover 1 moves upward, with a certain point (near point A in Figure 1, according to Example 1) acting as a pivot point. This reduces the gap between the ceiling and the upper front edge of the cover 1, improving the appearance of the range hood 9 when viewed from the front.
[0026] In this case, if the height of the step in the second restricted portion 113 is greater than or equal to the thickness of the suspension bracket 2, the height of the front of the cover 1 will be higher (or at the same height) than the height of the top of the suspension bracket 2 (according to Embodiment 1, the top surface of the ceiling flap 2128), which may damage the ceiling. However, if the height of the step in the second restricted portion 113 is made less than the thickness of the suspension bracket 2, the height of the front of the cover 1 can be made lower than the top of the suspension bracket 2 (according to Embodiment 1, the top surface of the ceiling flap 2128). As a preferred example, according to Embodiment 1, the height of the horizontal plate 111 at point C in the figure and the height of the horizontal plate 111 at point B in the figure are set such that point C > point B, and the difference between the two is set to be less than the thickness of the suspension bracket 2.
[0027] If the step is high, it will be difficult for the worker to remove cover 1. If the step is low, the worker can tilt cover 1, which will raise the step of the second restricted part 113, making it easier to remove. By tilting the step, the worker can release the engagement and remove cover 1 simply by pulling it towards them, without having to lift it.
[0028] The restricting parts may be provided at one location on each of the pair of support bars 21, but as in Embodiment 1, there may be two in the front-rear direction on each of the pair of support bars 21, for a total of four. When there are two restricted parts, such as the first restricted part 112 and the second restricted part 113, the restricted parts (112, 113) and the restricting parts (2121, 2123) become less likely to come off, and the operator can feel a greater sense of grip when they engage them. The left-right and front-rear positions of the side panel 119 of the cover 1 can be reliably restricted at multiple locations on the side panel 119. In the installed state, the left-right position of the side panel 119 of the cover 1 can be stabilized without using a complex mechanism, and in particular, the side panel 119 of the cover 1 can be prevented from opening to the left or right, preventing the appearance of the range hood 9 from being damaged.
[0029] Furthermore, it is preferable to provide two first restricted portion 112 (step) and two second restricted portion 113 (step) on each of the pair of support bars 21 in Embodiment 1. Since a total of four steps face each other in the front-rear direction, the front-rear position can be stabilized as well as the left-right position.
[0030] Since the regulated and restricted areas can be covered over a wide area of the cover 1, the installation is secure and stable.
[0031] (Guidance for the restricting portion) The first restricting portion 2121 (groove-shaped) shown in Figure 5 has a first guide portion 2122 which is an inclined portion that receives the first restricted portion 112 (step) on the support bar 21. The side plate 111 of the cover 1 (slide duct) moves along the first guide portion 2122 and engages with the first restricting portion 2121 (groove-shaped). In other words, as the cover 1 is moved from front to back along the support bar 21 of the suspension fitting 2, the left-right position of the first restricted portion 112 (step) is guided by the first guide portion 2122 so that the position of the first restricting portion 2121 (groove-shaped) and the position of the first restricted portion 112 (step) match. Furthermore, the second restricting section 2123 is connected to the second guide section 2124, and the second restricted section 113 (step) is guided by the second guide section 2124 and engages with the second restricting section 2123 (groove-shaped).
[0032] [Example 2] (Fixed by the third restricting portion 22 (projection)) Figure 6 is an explanatory diagram of Example 2 in which the hanging bracket 2 is provided with a third restricting portion 22 (projection) and the cover 1 is provided with a third restricted portion 122 (notch). The cover 1 and the hanging bracket 2 are assembled in the order of (a), (b), and (c). The hanging bracket 2 has a fixing portion 23 and is fixed to the wall surface with screws via wall mounting screw holes 231 provided in the fixing portion 23 (wall mounting portion). Support bars 21 are provided on both sides of the fixing portion 23 of the hanging bracket 2, as in Example 1.
[0033] The supported portion of Embodiment 2 consists of a third restricted portion 122 (notch) and a support bar receiving portion 13. When attaching the cover 1 to the hanging bracket 2, the support bar 21 of the hanging bracket 2 is inserted into the support bar receiving portion 13 of the cover 1. The cover 1 has a third restricted portion 122 (notch) directly below the support bar receiving portion 13.
[0034] Compared to cases where the regulating section is grooved, the cover 1 does not sag downwards, maintains a horizontal position with the ceiling, and reduces the gap with the ceiling, resulting in a superior appearance. In addition, there are no snags during attachment and detachment, making installation and removal work easy.
[0035] [Example 3] Figure 7 is an explanatory diagram of Example 3. (Step 1) In Step 1, the flap 11 of the cover 1 and the claw-forming portion 211 of the support bar 21 of the hanging bracket 2 are brought into close proximity. The flap 11 of the cover 1 is provided with a fourth restricted portion 141 (claw insertion portion) and a fifth restricted portion 142 (claw insertion portion). The fourth restricted portion 141 (claw insertion portion) and the fifth restricted portion 142 (claw insertion portion) are holes. The fourth restricted portion 24 (claw portion) and the fifth restricted portion 25 (claw portion) of the hanging bracket 2 are provided extending downward from the claw-forming portion 211 which is parallel to the ceiling.
[0036] In step 2, the flap 11 of the cover 1 and the support bar 21 of the hanging bracket 2 are moved in a facing position with a slight gap between them so as not to come into contact.
[0037] In step 3, the cover 1 is lifted so that the restricting portion and the restricted portion engage with the hanging bracket 2 fixed to the wall. As a result, the fourth restricted portion 141 (claw insertion portion) and the fifth restricted portion 142 (claw insertion portion) of the cover 1 engage, and the fourth restricting portion 24 (claw portion) and the fifth restricting portion 25 (claw portion) provided on the support bar 21 of the hanging bracket 2 engage. As a result, the cover 1 and the hanging bracket 2 become one unit. In this embodiment, the cover 1 side is the claw insertion portion and the hanging bracket 2 side is the claw portion, but the opposite may be used, where the cover 1 side is the claw portion and the hanging bracket 2 side is the claw insertion portion.
[0038] Compared to the configuration of the first embodiment, where the restricted portion of the cover 1 is stepped and the restricted portion of the hanging bracket 2 is grooved, the fourth embodiment has a better appearance because the width by which the cover 1 drops downward is smaller, and the gap with the ceiling is reduced. In addition, the fourth embodiment makes it easier to attach and detach the cover 1.
[0039] [Example 4] Although not shown in the figures, the restricting part and the restricted part in Example 4 are connected by magnetic force. The support bar 21 of the cover 1 or the hanging bracket 2 is provided with a magnet on either one or both sides as the restricting part or as the restricted part. The cover 1 is positioned by magnetic attraction when inserted into the support bar 21 to a predetermined position. The cover 1 or the hanging bracket 2 is made of a material that is not attracted to magnets, such as stainless steel, and magnetic steel or magnets are attached only to the predetermined positions that will become the restricting part and / or the restricted part.
[0040] Although embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and any design changes, etc., that do not depart from the gist of the present invention are also included. Furthermore, the above-described embodiments and each configuration can be combined by utilizing each other's technologies, as long as there are no particular contradictions or problems in their purpose and configuration. In particular, in the embodiments, the restricted portion is provided on the cover 1 side and the restricted portion is provided on the suspension fitting 2 side, but even if this relationship is reversed, it is still included in the present invention.
