Description

【０００１】
【発明の属する技術分野】
本発明は、調理時に発生する廃ガス、油煙、臭気などを確実に屋外へ排出するレンジフードに関する。
【０００２】
【従来の技術】
近年、レンジフードの普及に伴い、捕集性、掃除性などのより優れたレンジフードの要望が高まってきている。
【０００３】
従来、この種のレンジフードの一例として実公平６−２５７８６号公報に開示されているものが知られている。以下、その構成について図７および図８を参照しながら説明する。
【０００４】
図に示すように、側面形状が略三角形をしたフード本体１０１の前方開口部の下半部に案内板１０２を取り付け、その案内板１０２上端と天板１０１ａとの間にわたりフィルター１０３を取り付けるとともに、それらで区画された内部に送風機ユニット１０４を内蔵し、案内板１０２の上部から天板１０１ａにわたりフィルター１０３の前方を被い左右側板１０１ｂと所定の吸い込み間隙１０５を区画形成する遮蔽板１０６を着脱自在に取り付けていた。
【０００５】
【発明が解決しようとする課題】
このような従来のレンジフードでは、少量であれば遮蔽板１０６に当たった油煙は、左右側板１０１ｂと所定の吸い込み間隙１０５より吸い込まれるが、一度に多量の油煙が発生する際には、油煙を溜めておくための空間がないため、油煙は案内板１０２に当たることなく本体１０１の前部や、左右から大気中に拡散してしまうという問題があった。
【０００６】
本発明は、上記課題を解決するもので、一度に大量の油煙が発生しても、室内側に拡散することなく捕集することができるレンジフードを提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明のレンジフードにおいては、前面に吸気口を有し、上面に排気口を形成し、内部に前記吸気口と前記排気口に連通する送風機を設けた箱状の送風機ユニットと、この送風機ユニットの前方に連設される天板とほぼ三角形の側板と前記天板から下方に向けて延設される前板とからなるトップフードと、このトップフードの前記天板下面から内部に下方に向けて設けられる前面板と両側面に設けられる側面板と前記前面板下部より後方に延びる下面板と下面板に連設し後方に向かうに従い高さが低くなるように傾斜した下面傾斜板とを設けて前記トップフードとの間に捕集空間を形成し設けられるチャンバーボックスとを備え、前記前面板と前記側面板に内部と連通する前面吸込口と側面吸込口をそれぞれ設け、前記前面吸込口の上縁に前方に向かうに従い高さが低くなるように傾斜させた前面吸込口上面を形成し、下縁に吸込口内部に向かうに従い高さが高くなるように傾斜させた前面吸込口下面を形成し、前記前面吸込口と前記側面吸込口の下流側の前記チャンバーボックス内に両方の吸込口より吸い込まれた油煙をろ過するフィルターを設けた構成としたものである。
【０００８】
この本発明によれば、一度に大量の油煙が発生しても大気中に拡散することなく捕集するレンジフードを提供することができる。
【０００９】
【発明の実施の形態】
本発明の請求項１に記載の発明は、前面に吸気口を有し、上面に排気口を形成し、内部に前記吸気口と前記排気口に連通する送風機を設けた箱状の送風機ユニットと、この送風機ユニットの前方に連設される天板とほぼ三角形の側板と前記天板から下方に向けて延設される前板とからなるトップフードと、このトップフードの前記天板下面から下方に向けて延設される前面板と両側面に設けられる側面板と前記前面板下部より後方に延びる下面板と下面板に連設し後方に向かうに従い高さが低くなるよう傾斜した下面傾斜板とを設けて前記トップフードの内面との間に捕集空間を形成し設けられるチャンバーボックスとを備え、前記前面板と前記側面板に内部と連通する前面吸込口と側面吸込口をそれぞれ設け、前記前面吸込口の上縁に前方に向かうに従い高さが低くなるように傾斜させた前面吸込口上面を形成し、前記前面吸込口の下縁に吸込口内部に向かうに従い高さが高くなるように傾斜させた前面吸込口下面を形成し、前記前面吸込口と前記側面吸込口の下流側の前記チャンバーボックス内に両方の吸込口より吸い込まれた油煙をろ過するフィルターを設けたレンジフードであって、チャンバーボックスの側面板を、下面板および下面傾斜板より下方に延設し、前面板も下面板より下方に延設した構成としたことにより、調理時に大量に発生する油煙、排ガスなどは上昇気流にのり、大部分は前面吸込口および側面吸込口に直接吸い込まれ、一部はトップフードとチャンバーボックスとの間の捕集空間に捕集されたのち、前面吸込口および側面吸込口よりチャンバーボックス内に吸い込まれ、さらに、前面吸込口より前方に上昇し、トップフード外に漏れようとする油煙も、前面吸込口へ流入する気流に誘引されてチャンバーボックス内に吸い込まれるとともに、下面板まで誘導された油煙は、下面板より下方に延設した前面板に衝突して風速が減少し、チャンバーボックス捕集空間に停滞して前面吸込口および側面吸込口より吸込まれ、排気口より屋外へ排気されることとなり、一度に大量の油煙が発生しても室内側に拡散することなく捕集することができる。
【００１０】
以下、本発明の実施の形態について、図１〜図６を参照しながら説明する。
【００１１】
（実施の形態１）
図１〜図４に示すように、前面に吸気口１を有し、上面に排気口２を形成し、内部に吸気口１と排気口２に連通する送風機３を設けた箱状の送風機ユニット４と、送風機ユニット４の前方に連設される天板５とほぼ三角形の側板６と天板５の下面から下方に向けて延設される前板７とからなるトップフード８と、トップフード８の天板５の下面から下方に向けて設けられる前面板９と両側面に設けられる側面板１０と前面板９下部より後方に延びる下面板１１と下面板１１に連設し後方に向かうに従い高さが低くなるように傾斜した下面傾斜板１２とを設けた形状で、トップフード８との間に捕集空間１３を形成し設けられるチャンバーボックス１４とを備え、チャンバーボックス１４の前面板９と側面板１０に内部と連通する前面吸込口１５と側面吸込口１６をそれぞれ設け、前面吸込口１５の上縁を前方に向かうに従い高さが低くなるよう垂直に対して鋭角に傾斜させた前面吸込口上面１５ａを形成し、前面吸込口１５の下縁を吸込口内部に向かうに従い高さが高くなるように前面吸込口上面１５ａと平行に傾斜させた前面吸込口下面１５ｂを形成し、前面吸込口１５と側面吸込口１６の下流側のチャンバーボックス１４内に両方の吸込口より吸い込まれた油煙をろ過するフィルター１７を設け、トップフード８の前板７には送風機３の運転を制御するスイッチ１８を設け、送風機ユニット４の下面には調理台１９を照射するランプ２０を設け、排気口２には外気侵入防止用のダンパー２１を設けた構成する。
【００１２】
上記構成において、レンジを運転すると、調理時に発生する油煙や排ガスなどは上昇気流により下面傾斜板１２に沿って上昇し、チャンバーボックス１４の下面板１１に当り、前面吸込口１５および側面吸込口１６によりチャンバーボックス１４内に吸い込まれる。そして、チャンバーボックス１４の外側に逃げようとする一部の油煙や排ガスは、チャンバーボックス１４とトップフード８間に形成された捕集空間１３に一旦滞留されたのち、前面吸込口１５および側面吸込口１６よりチャンバーボックス１４内吸いこまれる。さらに、前面吸込口１５より前方に上昇してトップフード８の外側に漏れようとする油煙は、前面吸込口１５より前面吸込口上面１５ａと前面吸込口下面１５ｂとに沿って流入する垂直方向に対し鋭角な流れ方向をもつ前面吸気流２２に誘引されてチャンバーボックス１４内にフィルター１７を通過して吸い込まれ、フィルター１７によりろ過された空気は、吸気口１を通り送風機３により排気口２を経て屋外に排気されることとなる。
【００１３】
このように本発明の実施の形態１のレンジフードによれば、チャンバーボックス１４の下面板１１に下面傾斜板１２を連設し、後方に向かうに従い高さが低くなるように傾斜させたので、油煙や、排ガスは四方に拡散することなく、チャンバーボックス１４に沿い上昇し、前面吸込口１５および側面吸込口１６より吸い込まれ捕集効率が向上することとなる。そして、送風機ユニット４の前方に設けられるトップフード８との間に捕集空間１３が形成されるように、前面吸込口１５を有した前面板９と、側面吸込口１６を有した側面板１０と、下面板１１と、下面傾斜板１２とからなるチャンバーボックス１４を設けたので、調理時に発生する大量の油煙や排ガスは直接前面吸込口１５および側面吸込口１６に吸い込まれ、チャンバーボックス１４の外に逃げようとする油煙や排ガスは捕集空間１３に捕集されたのち、前面吸込口１５および側面吸込口１６に吸い込まれる。さらに、前面吸込口上面１５ａを前方に向かうに従い高さが低くなるよう傾斜させ、前面吸込口下面１５ｂを吸込口内部に向かうに従い高さが高くなるように前面吸込口上面１５ａと平行に傾斜させることにより、垂直方向に対し鋭角な方向に流入する前面吸気流２２を発生させて、図４示す油煙ベクトル２３のようなトップフード８の前方に漏れようとする油煙を誘引し、レンジフードの前方に油煙や排ガスが拡散されることを防止できる。
【００１４】
（実施の形態２）
図５に示すように、側面吸込口１６の上縁に側面吸込口上面１６ａを外側に向かうに従い高さが低くなるよう傾斜させて設けるとともに、下縁に側面吸込口下面１６ｂを吸込口内部に向かうに従い高さが高くなるように側面吸込口上面１６ａと平行に傾斜させて設ける。
【００１５】
上記構成において、調理時に発生し、側方からトップフード８の外側に漏れようとする油煙は、側面吸込口１６へ流入される垂直方向に対し鋭角で側面吸込口上面１６ａと側面吸込口下面１６ｂとに平行な流れ方向をもつ側面吸気流２４によりチャンバーボックス１４内にフィルター１７を通過して吸い込まれ、フィルター１７によりろ過された空気は吸気口１を通り送風機３により排気口２を経て屋外に排気されることとなる。
【００１６】
このように本発明の実施の形態２のレンジフードによれば、側面吸込口上面１６ａを外側に向かうに従い高さが低くなるよう傾斜させ、側面吸込口下面１６ｂを吸込口内部に向かうに従い高さが高くなるように傾斜させたので、垂直方向に対し鋭角な方向に流入する側面吸気流２４を発生させて、図５に示す油煙ベクトル２５のようなトップフード８の外側に漏れようとする油煙を誘引してレンジフードの外側に油煙や排ガスが放散されることを防止できる。
【００１７】
（実施の形態３）
図６に示すように、チャンバーボックス１４の側面板１０を、下面板１１および下面傾斜板１２より下方に延設し、前面板９も下面板１１より下方に延設する。
【００１８】
上記構成において、コンロ（図示せず）上方より発生した油煙上昇気流２７は、下面傾斜板１２より下方に延設した側面板１０に左右を囲まれた下面傾斜板１２に沿い上昇し、下面板１１に沿いながら水平方向に向きを変え、チャンバーボックス１４の下面板１１より下方に延設した前面板９に衝突し、速度を落として、チャンバーボックス捕集空間２６に停滞し、前面吸込口１５および側面吸込口１６からチャンバーボックス１４内にフィルター１７を通過して吸い込まれ、フィルター１７によりろ過された空気は吸気口１を通り送風機３により排気口２を経て屋外に排気されることとなる。
【００１９】
このように本発明の実施の形態３のレンジフードによれば、チャンバーボックス１４の側面板１０を、下面板１１および下面傾斜板１２より下方に延設し、前面板９も下面板１１より下方に延設したので、コンロ（図示せず）上方より発生する油煙上昇気流２７を前面吸込口１５および側面吸込口１６近傍の下面板１１まで誘導し、チャンバーボックス１４の下面板１１より下方に延設した前面板９に衝突させることにより風速を減少させ、チャンバーボックス捕集空間２６に停滞させて前面吸込口１５および側面吸込口１６より吸気することになり、大量に発生した油煙や排ガスをレンジフードの外に漏れることなく捕集することができる。
【００２０】
【発明の効果】
以上の実施の形態から明らかなように、前面に吸気口を有し、上面に排気口を形成し、内部に前記吸気口と前記排気口に連通する送風機を設けた箱状の送風機ユニットと、この送風機ユニットの前方に連設される天板とほぼ三角形の側板と前記天板から下方に向けて延設される前板とからなるトップフードと、このトップフードの前記天板の下面から下方に向けて設けられる前面板と両側面に設けられる側面板と前記前面板下部より後方に延びる下面板と下面板に連設し後方に向かうに従い高さが低くなるように傾斜した下面傾斜板とを前記吸気口を囲むように設けた形状で、前記トップフードとの間に捕集空間を形成し設けられるチャンバーボックスとを備え、前記前面板と前記側面板に内部と連通する前面吸込口と側面吸込口をそれぞれ設け、前記前面吸込口の上縁に前方に向かうに従い高さが低くなるように傾斜させた前面吸込口上面を形成し、前記前面吸込口の下縁に吸込口内部に向かうに従い高さが高くなるように傾斜させた前面吸込口下面を形成し、前記前面吸込口と前記側面吸込口の下流側の前記チャンバーボックス内に両方の吸込口より吸い込まれた油煙をろ過するフィルターを設けたので、一度に大量に発生した油煙は、トップフードのとくに前方に拡散することなく捕集することができる。
【００２１】
また、側面吸込口の上縁に側面吸込口上面を外側に向かうに従い高さが低くなるように傾斜させて設けるとともに、下縁に側面吸込口下面を吸込口内部に向かうに従い高さが高くなるように傾斜させて設けたので、側面吸気流を発生させて、レンジフード外側に漏れる油煙、排ガスをスムーズに誘引して、より捕集効率を向上させることができる。
【００２２】
また、チャンバーボックスの側面板を、下面板および下面傾斜板より下方に延設し、前面板も下面板より下方に延設したので、大量に発生した油煙や排ガスはチャンバーボックス捕集空間に停滞し、前面吸込口および側面吸込口から吸気されて、レンジフードの外側に漏れることなく捕集することができる。

[0011]
(Embodiment 1)
As shown in FIGS. 1 to 4, a box-shaped fan unit having an air inlet 1 on the front surface, an exhaust port 2 formed on the upper surface, and a fan 3 communicating with the air inlet 1 and the air outlet 2 inside. 4, a top hood 8 comprising a top plate 5 provided in front of the blower unit 4, a substantially triangular side plate 6 and a front plate 7 extending downward from the lower surface of the top plate 5, and a top hood As shown in FIG. 8, the front plate 9 is provided downward from the lower surface of the top plate 5, the side plates 10 are provided on both side surfaces, the lower plate 11 and the lower plate 11 extending rearward from the lower portion of the front plate 9, and the rear plate is moved backward. The front plate 9 of the chamber box 14 includes a chamber box 14 provided with a collection space 13 formed between the bottom hood 8 and the top hood 8 in a shape in which the lower inclined plate 12 is inclined so as to be lowered. Front suction port 1 communicating with the inside of the side plate 10 And a side suction port 16 are formed, and a front suction port upper surface 15a is formed that is inclined at an acute angle with respect to the vertical so that the height of the upper edge of the front suction port 15 decreases toward the front. A front suction port lower surface 15b that is inclined in parallel with the front suction port upper surface 15a so as to increase in height toward the inside of the suction port is formed, and a chamber on the downstream side of the front suction port 15 and the side suction port 16 A filter 17 is provided in the box 14 for filtering oil smoke sucked from both suction ports, a switch 18 for controlling the operation of the blower 3 is provided on the front plate 7 of the top hood 8, and cooking is performed on the lower surface of the blower unit 4. A lamp 20 for irradiating the base 19 is provided, and a damper 21 for preventing intrusion of outside air is provided at the exhaust port 2.
[0012]
In the above configuration, when the range is operated, oily smoke, exhaust gas, etc. generated during cooking rises along the lower inclined plate 12 due to the rising airflow, hits the lower plate 11 of the chamber box 14, and the front suction port 15 and the side suction port 16. Is sucked into the chamber box 14. Then, a part of the oily smoke and exhaust gas trying to escape to the outside of the chamber box 14 is once retained in the collection space 13 formed between the chamber box 14 and the top hood 8, and then the front suction port 15 and the side suction. It is sucked into the chamber box 14 from the mouth 16. Further, the oil smoke that rises forward from the front suction port 15 and leaks to the outside of the top hood 8 flows in the vertical direction from the front suction port 15 along the front suction port upper surface 15a and the front suction port lower surface 15b.

Is inclined so as to increase, so that a side intake air flow 24 that flows in an acute angle with respect to the vertical direction is generated, and oil smoke that leaks outside the top hood 8 like the oil smoke vector 25 shown in FIG. It is possible to prevent oil smoke and exhaust gas from being diffused outside the range hood.
[0017]
(Embodiment 3)
As shown in FIG. 6, the side plate 10 of the chamber box 14 extends below the lower plate 11 and the lower inclined plate 12, and the front plate 9 also extends below the lower plate 11.
[0018]
In the configuration described above, the oil smoke rising airflow 27 generated from above the stove (not shown) rises along the bottom inclined plate 12 surrounded by the side plate 10 extending downward from the bottom inclined plate 12, and the bottom plate 11 is changed in the horizontal direction while colliding with the front plate 9, collides with the front plate 9 extending downward from the lower plate 11 of the chamber box 14, reduces the speed, stays in the chamber box collection space 26, and enters the front suction port 15. The air that has been sucked into the chamber box 14 through the filter 17 from the side suction port 16 and filtered by the filter 17 passes through the intake port 1 and is exhausted to the outside through the exhaust port 2 by the blower 3.
[0019]

As is clear from the above embodiment, a box-shaped fan unit having an air inlet on the front surface, an exhaust port formed on the upper surface, and a fan communicating with the air inlet and the air outlet inside is provided. A top hood comprising a top plate continuously provided in front of the blower unit, a substantially triangular side plate, and a front plate extending downward from the top plate, and downward from the bottom surface of the top plate of the top hood A front plate provided toward the side, side plates provided on both sides, a lower plate extending rearward from the lower portion of the front plate, a lower inclined plate connected to the lower plate, and inclined so that the height decreases toward the rear And a chamber box provided to form a collection space between the top hood and the front hood, and a front suction port that communicates with the front plate and the side plate. Each side inlet Forming an upper surface of the front suction port that is inclined so as to decrease in height toward the upper edge of the front suction port, and increasing in height toward the inside of the suction port at the lower edge of the front suction port. Since the front suction port lower surface inclined so as to be formed and provided with a filter for filtering the oil smoke sucked from both suction ports in the chamber box on the downstream side of the front suction port and the side suction port, Oil smoke generated in large quantities at a time can be collected without spreading in front of the top hood.
[0021]
In addition, the upper surface of the side suction port is inclined at the upper edge of the side suction port so that the height decreases toward the outside, and the height increases as the lower surface of the side suction port moves toward the inside of the suction port at the lower edge. Thus, it is possible to improve the collection efficiency by generating a side air intake flow and smoothly attracting the oil smoke and exhaust gas leaking to the outside of the range hood.
[0022]
In addition, the side plate of the chamber box is extended below the lower plate and the lower inclined plate, and the front plate is also extended below the lower plate, so that a large amount of oil smoke and exhaust gas stagnates in the chamber box collection space. Then, it is sucked from the front suction port and the side suction port and can be collected without leaking outside the range hood.
