Abstract

To improve workability regarding removal of a flow straightening plate which controls an airflow sucked in a range hood.SOLUTION: A range hood 100 includes: a hood 10; a flow straightening plate 20 arranged below the hood 10; a flow straightening plate attaching/detaching device 30 for attaching/detaching the flow straightening plate 20 with respect to the hood 10. The flow straightening plate attaching/detaching device 30 includes a flow straightening plate locking part 32 for locking or cancelling the locking of the flow straightening plate 20 with respect to the hood 10. Since the flow straightening plate locking part 32 is arranged so as not to come into contact with a second standing part 35b included in a housing part 31 forming an outline of the flow straightening plate attaching/detaching device 30, friction does not occur between itself and the second standing part 35b when rotating the flow straightening plate locking part 32. Thus, the range hood is acquired which suppresses an external force required for cancelling the locked state of the flow straightening plate 20 increasing, and which improves workability regarding removal of the flow straightening plate 20.SELECTED DRAWING: Figure 3

Description

本発明は、レンジフードに関する。 The present invention relates to a range hood.

従来、この種のレンジフードは、加熱調理器等の上方に配置され、調理の過程で発生する油分を含む空気を吸込んで、屋外へ排気するものが知られている。また、油分を含む空気のうち、レンジフードに吸い込まれず屋内へ広がる空気の量を抑制するため、レンジフードに吸い込まれる空気の気流を制御する整流板をレンジフードの吸込口の下方へ配置したものも知られている。さらに、整流板はその配置場所から油汚れなどが付着しやすいため、定期的な清掃を行う必要があるので、整流板着脱装置を介して整流板をレンジフードに着脱可能に係止したものも知られている(例えば、特許文献1)。 Conventionally, it is known that this type of range hood is arranged above a cooking device or the like, sucks in air containing oil generated in the cooking process, and exhausts it to the outside. In addition, in order to suppress the amount of air containing oil that is not sucked into the range hood and spreads indoors, a straightening vane that controls the air flow of the air sucked into the range hood is placed below the suction port of the range hood. Is also known. Furthermore, since the straightening vane is prone to oil stains from its location, it is necessary to perform regular cleaning, so some straightening vanes are detachably locked to the range hood via a straightening vane attachment / detachment device. It is known (for example, Patent Document 1).

以下、そのレンジフードに備わる整流板着脱装置について、図4を参照しながら説明する。 Hereinafter, the straightening vane attachment / detachment device provided in the range hood will be described with reference to FIG.

図4に示すように、整流板着脱装置700は、フード800の下面に配置される。整流板着脱装置700は、筐体部710と、整流板900を係止するための板状の整流板係止部720と、整流板係止部720を付勢して筐体部710へ保持するための線材からなるバネ部730と、を備える。 As shown in FIG. 4, the straightening vane attachment / detachment device 700 is arranged on the lower surface of the hood 800. The straightening vane attachment / detachment device 700 urges a housing portion 710, a plate-shaped straightening vane locking portion 720 for locking the straightening vane plate 900, and a straightening vane locking portion 720 to hold the straightening plate mounting portion 710 to the housing portion 710. A spring portion 730 made of a wire rod for the purpose is provided.

整流板係止部720は、バネ部730に係止可能な凹部721を有する。 The straightening vane locking portion 720 has a recess 721 that can be locked to the spring portion 730.

整流板900は、図示しない開口を有し、該開口と整流板係止部720とが勘合することにより、整流板着脱装置700に対して係止状態となる。 The straightening vane 900 has an opening (not shown), and when the opening and the straightening vane locking portion 720 are fitted together, the straightening vane 900 is locked to the straightening vane attachment / detachment device 700.

整流板900の係止状態を解除する場合には、整流板係止部720が筐体部710の内部へ移動する方向(矢印方向A)へ外力を加える。すると、バネ部730が弾性変形しつつ、整流板係止部720は凹部721を支点に回動しながら筐体部710内へ収納されるので、整流板着脱装置700に対する整流板900の係止状態は解除される。 When releasing the locked state of the straightening vane 900, an external force is applied in the direction in which the straightening vane locking portion 720 moves inside the housing portion 710 (arrow direction A). Then, while the spring portion 730 is elastically deformed, the straightening vane locking portion 720 is housed in the housing portion 710 while rotating around the recess 721 as a fulcrum, so that the straightening vane 900 is locked to the straightening vane attachment / detachment device 700. The state is released.
