Description

抽油煙機Range hood

[0001] 本發明係有關一種將加熱調理時所發生之油煙等予以捕集並排出的抽油煙機。[0001] The present invention relates to a range hood that captures and discharges cooking fumes generated during heating and conditioning.

[0002] 先前，作為抽油煙機，為人所知的是具備排煙罩、濾器及送風機，藉由驅動送風機而將加熱調理時所發生之油煙等捕集於排煙罩內，並將捕集之油煙等的油以濾器除去後再排出至屋外等之類型。 　　此類之抽油煙機，因油附著於濾器而會髒污，故而要將髒污之濾器更換成新的濾器或是將髒污之濾器洗淨。然而濾器更換作業、濾器洗淨作業不免麻煩。 　　是以，業界曾提案一種在將送風機驅動時，亦即抽油煙機運轉時，藉由對濾器照射紫外線而將附著於濾器的油予以分解除去的抽油煙機(例如參照專利文獻1)。 [先前技術文獻] [專利文獻] 　　[0003] [專利文獻1] 日本特開平10-174827號公報[0002] Previously, as a range hood, it is known to have a fume hood, a filter, and a blower. By driving the blower, the fume generated during heating and conditioning is trapped in the fume hood and trapped It is a type in which the oil that collects soot and other oil is removed by a filter and then discharged outside the house.　　This type of range hood will become dirty due to the oil adhering to the filter, so the dirty filter should be replaced with a new one or the dirty filter should be cleaned. However, filter replacement and filter cleaning operations are unavoidable.　　 Therefore, the industry has proposed a range hood that decomposes and removes oil attached to the filter by irradiating the filter with ultraviolet rays when the blower is driven, that is, when the range hood is operating (for example, refer to Patent Document 1). [Prior Art Document] [Patent Document] 　　[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 10-174827

[發明解決之課題] 　　[0004] 然而，抽油煙機運轉時若對濾器照射紫外線，則因流動於排煙罩內之油煙等而使得照射於濾器之紫外線的一部分受到遮蔽，因而無法將紫外線有效率地照射於濾器，導致附著於濾器的油之紫外線分解能力低。 　　為了消除此一現象，專利文獻1所揭示之抽油煙機，係在與排煙罩內之油煙等流過的流路不同之位置設置紫外線光源，並將濾器以在面臨流路之位置與對向於紫外線光源之位置間可跨越移動的方式設置成可旋轉，在流動於排煙罩內之油煙等不遮蔽照射於濾器之紫外線下，將紫外線有效率地照射於濾器，而提升附著於濾器的油之紫外線分解能力。 　　然而，即便為此一構成，油煙等之一部分還是會流至濾器與紫外線光源之間，因此照射於濾器之紫外線的一部分會被油煙等遮蔽，而無法有效率地將紫外線照射於濾器，因此紫外線之油分解能力幾乎無法提高。 　　[0005] 為了消除此一現象，本發明人等曾提案在抽油煙機運轉停止後對於濾器照射紫外線，藉而可在與排煙罩內流動之油煙等無關的情況下將紫外線有效率地照射於濾器，而充分地提高紫外線之油分解能力。 　　然而，對於附著有油之濾器照射紫外線將油分解之際，油的氧化經促進，除發出惡臭外還會產生臭氧。 　　因此，在抽油煙機運轉停止後將紫外線照射於濾器此舉，除會令室內之人感覺到惡臭而不舒適之外，臭氧還會充滿於室內，而有對人體帶來不良影響之虞。 　　[0006] 本發明係有鑑上述課題而完成者，其目的係在提供一種可在與流動於排煙罩內之油煙等無關的情況下將紫外線有效率地照射於濾器，而且室內之人不會感覺到惡臭，同時臭氧不致充滿於室內的抽油煙機。 [用以解決課題之手段] 　　[0007] 本發明之第1抽油煙機，其特徵在於：此抽油煙機具備：排煙罩、濾器、以風扇用馬達將風扇旋轉之送風機、對於上述濾器照射紫外線之紫外線光源、及控制上述風扇用馬達與上述紫外線光源之控制部；上述控制部，於自運轉狀態停止運轉之後，係將上述紫外線光源以設定時間點亮，同時將上述風扇用馬達以上述設定時間驅動而使上述風扇於上述紫外線照射中旋轉。 　　[0008] 本發明之第2抽油煙機，其特徵在於：此抽油煙機具備：排煙罩、濾器、以風扇用馬達將風扇旋轉之送風機、對於上述濾器照射紫外線之紫外線光源、及控制上述風扇用馬達與上述紫外線光源之控制部；上述控制部，於自運轉狀態停止運轉之後，係將上述紫外線光源以設定時間點亮，同時將上述風扇用馬達驅動，而即便在上述設定時間經過而紫外線光源熄燈後，也仍使上述風扇用馬達驅動一定時間，而使上述風扇即使在上述紫外線光源熄燈後仍旋轉一定時間。 　　[0009] 本發明之第1或第2抽油煙機中，可行的構成是，設置旋轉上述濾器之濾器用馬達，且上述控制部在上述運轉停止後將上述濾器用馬達以特定時間高速驅動而將上述濾器在紫外線照射之前以特定時間高速旋轉，而在上述特定時間經過後，控制上述紫外線光源及上述風扇用馬達。 　　若是如此設置，附著於濾器的油的一部分將會飛散至濾器之周圍而被除去，因此殘存之油以紫外線照射分解即可，故而可容易地將油分解。又，由於係將多量的油除去而在濾器上只有最小限度的油附著之狀態下照射紫外線，因此可縮短紫外線之照射時間。 　　[0010] 本發明之第1至第3任一種之抽油煙機中，可行的構成是，設置旋轉上述濾器之濾器用馬達，且上述控制部，在上述設定時間經過之後將上述濾器用馬達高速驅動而使上述濾器高速旋轉。 　　若是如此設置，附著於濾器的油因紫外線照射而分解所產生之水係藉由濾器旋轉而以離心力飛散至濾器之周圍，因此可將水自濾器除去。 　　[0011] 本發明之第1至第4任一種之抽油煙機中，可行的構成是，設置旋轉上述濾器之濾器用馬達，且上述控制部，在上述設定時間經過之後將上述濾器用馬達高速驅動而使上述濾器高速旋轉。 　　若是如此設置，附著於濾器的油，在油分解時與必要之氧接觸的機會多，可將油有效率地分解。 　　[0012] 本發明之第1至第4任一種之抽油煙機中，可行的構成是，設置旋轉上述濾器之濾器用馬達，且上述控制部在上述紫外線光源點亮之期間，將上述濾器用馬達低速驅動而將上述濾器於紫外線照射中低速旋轉。 　　若是如此設置，照射至濾器之單位面積的紫外線之量增多，以致將附著於濾器的油分解的能力優異，可將附著於濾器的油充分分解而將油自濾器確實除去。 　　[0013] 根據本發明之第1、第2之抽油煙機，由於係在運轉停止後對於濾器照射紫外線，因此與在排煙罩內流動之油煙等無關，可將紫外線有效率地照射於濾器。 　　因此，基於紫外線照射之油的分解能力優異，可將濾器潔淨地洗淨。 　　而且，將紫外線照射於濾器時，由於送風機之風扇旋轉，因此因油分解所產生之惡臭、臭氧，可由送風機排出。 　　因此，室內之人不會感覺到惡臭，且臭氧也不會充滿於室內。 　　根據本發明之第2抽油煙機，在紫外線照射後送風機之風扇仍然旋轉，因此可將因油分解所產生之惡臭、臭氧確實地排出。[Problem to be solved by the invention] 　　[0004] However, if ultraviolet rays are irradiated to the filter during operation of the range hood, part of the ultraviolet rays irradiated on the filter will be shielded by the oil fume flowing in the fume hood, so that the ultraviolet rays cannot be protected. Effectively irradiate the filter, resulting in low UV decomposition ability of the oil adhering to the filter. In order to eliminate this phenomenon, the range hood disclosed in Patent Document 1 installs an ultraviolet light source at a position different from the flow path through which the oil fume and the like in the fume exhaust hood flow, and places the filter on the position facing the flow path. It is set to be rotatable in a way that can move across the position of the ultraviolet light source, so that the oil fume flowing in the exhaust hood does not shield the ultraviolet rays irradiated on the filter, and the ultraviolet rays are effectively irradiated to the filter, and the attachment to the filter is improved. The UV decomposability of the oil. However, even with this configuration, a part of oily smoke will flow between the filter and the ultraviolet light source. Therefore, part of the ultraviolet rays irradiated on the filter will be shielded by the oily smoke, and the ultraviolet rays cannot be irradiated to the filter efficiently. The oil decomposition ability can hardly be improved. [0005] In order to eliminate this phenomenon, the inventors of the present invention have proposed to irradiate the filter with ultraviolet rays after the range hood is stopped, so that the ultraviolet rays can be efficiently irradiated regardless of the oily smoke flowing in the fume hood. For the filter, it can fully improve the oil decomposition ability of ultraviolet rays.　　 However, when a filter with oil attached is irradiated with ultraviolet rays to decompose the oil, the oxidation of the oil is promoted, and ozone is generated in addition to the offensive odor.　　 Therefore, irradiating ultraviolet rays to the filter after the range hood stops running will not only make people in the room feel bad and uncomfortable, but the ozone will also fill the room, which may cause adverse effects on the human body. [0006] The present invention has been completed in view of the above-mentioned problems, and its purpose is to provide a filter that can efficiently irradiate ultraviolet rays to the filter regardless of the oily smoke flowing in the fume hood, and that the people in the room are not A foul smell will be felt, and the ozone will not fill the indoor range hood. [Means to Solve the Problem] 　　[0007] The first range hood of the present invention is characterized in that the range hood includes: an exhaust hood, a filter, a blower that rotates the fan with a fan motor, and irradiates the filter The ultraviolet light source for ultraviolet rays, and the control unit that controls the fan motor and the ultraviolet light source; the control unit turns on the ultraviolet light source for a set time after stopping operation from the operating state, and at the same time turns the fan motor on It is driven for a set time to rotate the fan during the ultraviolet irradiation. [0008] The second range hood of the present invention is characterized in that the range hood includes: an exhaust hood, a filter, a blower that rotates the fan with a fan motor, an ultraviolet light source that irradiates ultraviolet rays to the filter, and the control The fan motor and the control unit of the ultraviolet light source; the control unit turns on the ultraviolet light source for a set time after stopping operation from the operating state, and drives the fan with the motor at the same time, even if the set time elapses After the ultraviolet light source is turned off, the fan is still driven by the motor for a certain period of time, and the fan is rotated for a certain period of time even after the ultraviolet light source is turned off. [0009] In the first or second range hood of the present invention, it is possible to provide a filter motor that rotates the filter, and the control unit drives the filter motor at a high speed for a specific time after the operation is stopped. The filter is rotated at a high speed for a specific time before ultraviolet irradiation, and after the specific time has elapsed, the ultraviolet light source and the fan motor are controlled.　　If set in this way, part of the oil adhering to the filter will scatter around the filter and be removed. Therefore, the remaining oil can be decomposed by ultraviolet radiation, so the oil can be easily decomposed. In addition, since a large amount of oil is removed and ultraviolet rays are irradiated in a state where only a minimum of oil adheres to the filter, the irradiation time of ultraviolet rays can be shortened. [0010] In the range hood of any one of the first to third of the present invention, a possible configuration is that a filter motor that rotates the filter is provided, and the control unit turns the filter motor at a high speed after the set time has elapsed. The filter is driven to rotate at a high speed.　　If it is installed in this way, the water produced by the decomposition of the oil attached to the filter due to ultraviolet radiation is scattered around the filter by centrifugal force by the rotation of the filter, so the water can be removed from the filter. [0011] In the range hood of any one of the first to the fourth of the present invention, a possible configuration is that a filter motor that rotates the filter is provided, and the control unit turns the filter motor at a high speed after the set time has elapsed. The filter is driven to rotate at a high speed.　　If set in this way, the oil adhering to the filter has many chances to come into contact with the necessary oxygen when the oil is decomposed, and the oil can be decomposed efficiently. [0012] In the range hood of any one of the first to the fourth of the present invention, a possible configuration is that a filter motor that rotates the filter is provided, and the control unit uses the filter while the ultraviolet light source is on. The motor is driven at a low speed to rotate the filter at a low speed during ultraviolet irradiation.　　If set in this way, the amount of ultraviolet rays per unit area irradiated to the filter is increased, so that the ability to decompose the oil attached to the filter is excellent, and the oil attached to the filter can be fully decomposed and the oil can be reliably removed from the filter. [0013] According to the range hoods of the first and second embodiments of the present invention, the filter is irradiated with ultraviolet rays after the operation is stopped. Therefore, the filter can be efficiently irradiated with ultraviolet rays regardless of the oil smoke flowing in the exhaust hood. .　　 Therefore, the oil decomposing ability based on ultraviolet radiation is excellent, and the filter can be cleanly washed.　　 Moreover, when the filter is irradiated with ultraviolet rays, the fan of the blower rotates, so the odor and ozone generated by the decomposition of the oil can be discharged by the blower.　　 Therefore, people in the room will not feel bad smell, and the ozone will not fill the room.　　 According to the second range hood of the present invention, the fan of the blower still rotates after the ultraviolet rays are irradiated, so the odor and ozone generated by the decomposition of the oil can be reliably discharged.

[0015] 茲將本發明之第1實施方式，參照第1圖、第2圖、第3圖進行說明。 　　第1圖為抽油煙機的剖視圖，第2圖為濾器安裝部的放大圖，第3圖為運轉操作部與控制部的說明圖。 　　抽油煙機1具備：排煙罩2、濾器3、送風機4、及紫外線光源5。 　　排煙罩2係由頂面板20、周面板21、下面板22所形成之高度低的矩形箱形狀。下面板22具有朝頂面板20凹入之凹部23，凹部23內安裝整流板24，由整流板24與凹部23形成流路25。流路25之下部係朝排煙罩2之下方開放，流路25之上部係於開口部26朝排煙罩2之上方開放。 　　濾器3係設於流路25，濾器3係與開口部26對向。藉此，流入流路25之油煙等將通過濾器3流至開口部26。此一實施方式之抽油煙機1的濾器3係由濾器用馬達30旋轉驅動。 　　[0016] 針對濾器3之安裝實施方式，參照第2圖進行說明。 　　排煙罩2之開口部26中安裝有板片31。板片31具有較濾器3之外徑稍小徑之孔31a，板片31上係以跨該孔31a之中心部的方式安裝有馬達安裝板32。馬達安裝板32之寬度係較孔31a之孔徑顯著地狹窄，使其不致成為流通經過孔31a之空氣的阻礙。馬達安裝板32之上面安裝有濾器用馬達30。 　　濾器用馬達30之旋轉軸30a係通過板片31之孔31a而突出至排煙罩2之流路25，其突出部安裝有濾器3。 　　板片31之下面上，係以包圍濾器3之方式安裝有環形狀之流體積留構件33。流體積留構件33係藉由內徑較濾器3之外徑為大之筒體33a、及於筒體33a之內周面下端周向連續地安裝之朝上鉤型片33b，而具有環形狀且下部具有周向連續而且朝上開口的流體積留部33c。 　　[0017] 如第1圖所示，送風機4具有：設於送風機箱40內之外殼41、設於外殼41內之風扇42、及旋轉風扇42之風扇用馬達43。 　　送風機箱40安裝於排煙罩2之頂面板20上，外殼41之吸氣孔41a係與排煙罩2之開口部26連通。外殼41之排氣孔41b係與排氣導管44連通。 　　藉此，經由以風扇用馬達43將風扇42旋轉，加熱調理時發生之油煙等，將可於流路25中被捕集於排煙罩2內。被捕集之油煙等的油係附著於濾器3而被除去，而該油煙以不含油之空氣由排氣導管44排出。 　　紫外線光源5係對濾器3之油附著面照射以紫外線。作為紫外線光源5可使用紫外線燈、LED、水銀燈等。 　　[0018] 於此一實施方式中，如第2圖所示，流體積留構件33之筒體33a的內周面上，周向隔以間隔地安裝有複數個紫外線燈作為紫外線光源5。 　　藉此，紫外線光源5對於朝濾器3流動之油煙等不構成阻礙。 　　紫外線光源5(紫外線燈)係斜向上地發出紫外線，可對濾器3之下面的全面(油附著面的全面)照射紫外線。又，紫外線燈只要可照射濾器3之下面全面即可，因此若為1個可照射濾器3之下面全面之廣大區域的紫外線燈，紫外線燈即使為1個也屬可行。 　　[0019] 如第1圖所示，排煙罩2之周面板21上，安裝有供將抽油煙機1運轉操作之運轉操作部6。 　　排煙罩2內設有控制部7。控制部7係根據來自運轉操作部6之指令而驅動控制風扇用馬達43，且將紫外線光源5作點亮、熄燈控制。 　　[0020] 如第3圖所示，運轉操作部6具有：強運轉開關60、中運轉開關61、弱運轉開關62、及停止開關63。 　　強運轉開關60在加熱調理器之加熱調理開始時被操作，對於控制部7輸出強運轉指令。中運轉開關61在加熱調理器之加熱調理開始時被操作，對於控制部7輸出中運轉指令。弱運轉開關62在加熱調理器之加熱調理開始時被操作，對於控制部7輸出弱運轉指令。 　　又，加熱調理中若操作不同之運轉開關將可輸出不同之運轉指令。 　　停止開關63在加熱調理器之加熱調理終了時被操作，對於控制部7輸出運轉停止指令7。 　　控制部7具有運轉控制部70及濾器洗淨控制部71。 　　[0021] 運轉控制部70，若強運轉指令輸入，則將送風機4之風扇用馬達43高速驅動而使送風機4之風扇42高速旋轉，令抽油煙機1作強運轉。若中運轉指令輸入，則將風扇用馬達43中速驅動而使送風機4之風扇42中速旋轉，令抽油煙機1作中運轉。若弱運轉指令輸入，則將風扇用馬達43低速驅動而使送風機4之風扇42低速旋轉，令抽油煙機1弱運轉。 　　運轉控制部70於抽油煙機1強運轉、中運轉、弱運轉中之狀態下若有運轉停止指令輸入，則停止風扇用馬達43之驅動，而中止送風機4之風扇42之旋轉，使抽油煙機1運轉停止。 　　[0022] 濾器洗淨控制部71若在抽油煙機1運轉中之狀態下，有運轉停止指令輸入時，則將紫外線光源5以設定時間點亮，且將風扇用馬達43以設定時間驅動，而將送風機4之風扇42以設定時間旋轉。 　　而後，自運轉停止指令輸入而始經過設定時間後，將紫外線光源5熄燈，且停止風扇用馬達43之驅動，而停止送風機4之風扇42的旋轉。 　　設定時間係指運轉停止指令輸入而始可將附著於濾器3的油分解除去之時間。又，也可設置為有運轉停止指令輸入時，運轉控制部70不使風扇用馬達43之驅動停止而設為持續驅動之狀態，而濾器洗淨控制部71在有運轉停止指令輸入時，送風機4之風扇42以設定時間旋轉。 　　[0023] 換言之，控制部7在加熱調理器終了加熱調理而運轉狀態之抽油煙機1運轉停止後，將紫外線光源5以設定時間點亮，於紫外線光源5點亮中，驅動風扇用馬達43而使送風機4之風扇42旋轉。 　　當設為使抽油煙機1與加熱調理器連動地運轉、停止的情況下，係以加熱調理器之ON指令使風扇用馬達43旋轉，以OFF指令使風扇用馬達43暫時驅動停止，並點亮紫外線光源5，且使風扇用馬達43再次驅動，藉而使得在紫外線光源5點亮中送風機4之風扇42旋轉。又，也可以OFF指令不使風扇用馬達43停止，而持續旋轉。 　　如此，在加熱調理器之加熱調理終了、運轉狀態之抽油煙機1運轉停止而油煙等不流動於排煙罩2之流路25的狀態下，對於濾器3照射紫外線而將附著的油分解除去，因此可與流動於排煙罩2內之油煙等無關地將紫外線有效率地照射於濾器3之油附著面。 　　[0024] 因而，附著於濾器3的油之分解能力優異，可將濾器3潔淨地洗淨。 　　而且，對於濾器3照射紫外線而將油分解時，送風機4之風扇42正在旋轉，因此可將油分解時產生之惡臭、臭氧以送風機4排出。 　　因此，可形成為室內之人不會感覺到惡臭，且臭氧不致充滿於室內之抽油煙機。 　　[0025] 其次，說明本發明之第2實施方式。 　　抽油煙機1之構成係與第1圖、第2圖所示之第1實施方式的抽油煙機1相同，控制部7係與第1實施方式之控制部7不同。 　　控制部7係如第3圖所示之控制部7般之具有運轉控制部70與濾器洗淨控制部71。 　　濾器洗淨控制部71在運轉停止指令輸入時，如第1實施方式之濾器洗淨控制部71般之將紫外線光源5以設定時間發光，且驅動風扇用馬達43而使送風機4之風扇42旋轉。 　　自運轉停止指令輸入而始經過設定時間後，將紫外線光源5熄燈，且持續驅動風扇用馬達43，在經過一定時間後，停止風扇用馬達43之驅動而停止送風機4之風扇42的旋轉。 　　[0026] 換言之，控制部7在自抽油煙機1運轉中之狀態而停止運轉後，令紫外線光源5發光，且使送風機4之風扇42旋轉。控制部7在運轉停止而始經過設定時間後，將紫外線光源5熄燈，而送風機4之風扇42持續旋轉，在經過一定時間後，停止送風機4之風扇42的旋轉。 　　第2實施方式之控制部7，係如此般之控制紫外線光源5、風扇用馬達43，因此在對濾器3照射紫外線而將油分解時所產生之惡臭、臭氧，在紫外線照射中及紫外線照射後係由送風機4排出。 　　因此，可確實排出惡臭、臭氧。 　　如是，在第1、第2實施方式中由於濾器用馬達30不動作，因此不設置濾器用馬達30也可。亦即，第1、第2實施方式之抽油煙機，也可為具備利用濾器用馬達30而可旋轉之濾器3的抽油煙機，也可為不具有濾器用馬達30而具備不可旋轉之濾器3的抽油煙機。 　　[0027] 其次，說明本發明之第3實施方式。 　　抽油煙機1之構成係與第1圖、第2圖所示之第1實施方式之抽油煙機1相同，控制部7係與第1實施方式之控制部7不同。 　　控制部7係如第4圖所示，具有運轉控制部70及濾器洗淨控制部71。 　　運轉控制部70係與第1實施方式之運轉控制部70相同。 　　濾器洗淨控制部71在將紫外線光源5、風扇用馬達43以如同第1實施方式或第2實施方式般之控制之前，係將濾器用馬達30作如下般之控制。 　　在運轉指令輸入中之狀態下，若有運轉停止指令輸入，則在紫外線光源5之發光、風扇用馬達43之驅動之前，使濾器用馬達30以特定時間高速驅動而將濾器3以特定時間高速旋轉。 　　[0028] 特定時間經過後，停止濾器用馬達30之驅動而停止濾器3之旋轉。 　　換言之，在紫外線照射前，使濾器3以特定時間高速旋轉。自運轉停止指令輸入而始經過特定時間後，將紫外線光源5與風扇用馬達43如同第1實施方式或第2實施方式般之控制。又，可在特定時間經過後，繼續濾器用馬達30之驅動而繼續濾器3之旋轉。 　　[0029] 如是，藉由在對濾器3照射紫外線前，使濾器3高速旋轉，附著於濾器3的油之一部分將飛散至濾器3之周圍而自濾器3除去。 　　因而，將殘存於濾器3的油以紫外線分解即可，可利用紫外線將附著於濾器3的油容易地分解。又，由於係將多量的油除去而在濾器3僅附著最小限度之油的狀態下照射紫外線，因此可縮短紫外線之照射時間。 　　飛散於濾器3之周圍的油，係積留於流體積留構件33之流體積留部33c，因此不會造成排煙罩2之髒污。 　　[0030] 其次，說明本發明之第4實施方式。 　　抽油煙機1之構成係與第1圖、第2圖所示之第1實施方式的抽油煙機1相同，控制部7係與第1實施方式之控制部7不同。 　　控制部7係如第4圖所示，具有運轉控制部70及濾器洗淨控制部71。 　　運轉控制部70係與第1實施方式之運轉控制部70相同。 　　濾器洗淨控制部71係將紫外線光源5與風扇用馬達43如同第1實施方式或第2實施方式般之控制。與此同時，將濾器用馬達30作如下般之控制。 　　在運轉指令被輸入中之狀態下，若有運轉停止指令輸入，經過紫外線光源5之發光設定時間而紫外線光源5熄燈後，將濾器用馬達30以一定時間高速驅動而將濾器3以一定時間高速旋轉。一定時間經過後，停止濾器用馬達30之驅動而停止濾器3之旋轉。 　　[0031] 如此，藉由在對濾器3照射紫外線終了後，將濾器3高速旋轉，附著於濾器3之油分解所發生之水將飛散至濾器3之周圍而自濾器3經除去。 　　換言之，因附著於濾器3之油因紫外線之照射而分解成水及二氧化碳，因此藉由將濾器3高速旋轉，可將濾器3上之水以離心力飛散至周圍而除去。 　　二氧化碳係由送風機4排出。 　　飛散至濾器3之周圍的水，係積留於流體積留構件33之流體積留部33c，因此水不會流入排煙罩2內。 　　又，與第3實施方式相同，也可行的是，在運轉指令輸入中之狀態下，若有運轉停止指令輸入，則在紫外線光源5之發光、風扇用馬達43之驅動之前，使濾器用馬達30以特定時間高速驅動而將濾器3以特定時間高速旋轉。 　　[0032] 其次，說明本發明之第5實施方式。 　　抽油煙機1之構成係與第1圖、第2圖所示之第1實施方式之抽油煙機1相同，控制部7係與第1實施方式之控制部7不同。 　　控制部7係如第4圖所示，具有運轉控制部70及濾器洗淨控制部71。 　　運轉控制部70係與第1實施方式之運轉控制部70相同。 　　濾器洗淨控制部71係將紫外線光源5及風扇用馬達43以如同第1實施方式或第2實施方式般之控制。與此同時，濾器用馬達30係作如下述般之控制。 　　在運轉指令輸入中之狀態下，若有運轉停止指令輸入，則與紫外線光源5之發光同時，將濾器用馬達30以與紫外線光源5之發光時間相同之設定時間高速驅動而將濾器3以設定時間高速旋轉。設定時間經過後，停止濾器用馬達30之驅動而停止濾器3之旋轉。換言之，在紫外線之照射中使濾器3高速旋轉。 　　[0033] 如是，藉由在對濾器3照射紫外線中，將濾器3高速旋轉，附著於濾器3的油，與將油分解時所需的氧接觸之機會多，可將油有效率地分解。 　　又，與第3實施方式相同，也可行的是，在運轉指令輸入中之狀態下，若有運轉停止指令輸入，則在紫外線光源5之發光、風扇用馬達43之驅動之前，使濾器用馬達30以特定時間高速驅動而將濾器3以特定時間高速旋轉。又，與第4實施方式相同，也可行的是，在運轉指令輸入中之狀態下，若有運轉停止指令輸入，則在經過紫外線光源5之發光設定時間而紫外線光源5熄燈後，將濾器用馬達30以一定時間高速驅動而將濾器3以一定時間高速旋轉。也可在一定時間經過後，停止濾器用馬達30之驅動而停止濾器3之旋轉。 　　又，以上係就濾器用馬達30與紫外線光源5之發光同時作高速驅動，而將濾器3以設定時間高速旋轉進行說明，但不限於此，濾器用馬達30之高速驅動也可不與紫外線光源5之發光同時。亦即，濾器用馬達30之高速驅動可與紫外線光源5之發光非為同時，而自發光而始經過短暫時間再開始，濾器用馬達30之高速驅動時間也不限於設定時間，也可為設定時間中之一部分的時間。以設定時間中之一部分的時間濾器用馬達30作高速驅動的情形下，停止狀態與高速驅動狀態可間歇地進行。 　　[0034] 其次，說明本發明之第6實施方式。 　　抽油煙機1之構成係與第1圖、第2圖所示之第1實施方式之抽油煙機1相同，控制部7係與第1實施方式之控制部7不同。 　　控制部7係如第4圖所示，具有運轉控制部70及濾器洗淨控制部71。 　　運轉控制部70係與第1實施方式之運轉控制部70相同。 　　濾器洗淨控制部71係將紫外線光源5與風扇用馬達43以如同第1實施方式或第2實施方式般之控制。與此同時，將濾器用馬達30作如下般之控制。 　　在運轉指令輸入中之狀態下，若運轉停止指令輸入，則與紫外線光源5之發光同時，將濾器用馬達30以與紫外線光源5之發光時間相同之設定時間低速驅動而將濾器3以設定時間低速旋轉。換言之，紫外線之照射中，將濾器3低速旋轉。 　　設定時間經過後，停止濾器用馬達30之驅動而停止濾器3之旋轉。 　　又，也可在設定時間經過後，繼續濾器用馬達30之驅動而繼續濾器3之旋轉。 　　[0035] 如此，在對濾器3照射紫外線中，藉由將濾器3低速旋轉，照射至濾器3之單位面積的紫外線之量增多，將附著於濾器3的油分解之能力優異。 　　因而，可將附著於濾器3的油充分分解而將油自濾器3確實除去。 　　又，與第3實施方式相同，可行的是，在運轉指令輸入中之狀態下，若運轉停止指令輸入，則在紫外線光源5之發光、風扇用馬達43之驅動之前，將濾器用馬達30以特定時間高速驅動而將濾器3以特定時間高速旋轉。又，與第4實施方式相同，在運轉指令輸入中之狀態下，若運轉停止指令輸入，則在經過紫外線光源5之發光設定時間而紫外線光源5熄燈後，將濾器用馬達30以一定時間高速驅動而將濾器3以一定時間高速旋轉。可在一定時間經過後，停止濾器用馬達30之驅動而停止濾器3之旋轉。 　　再者，以上係就濾器用馬達30與紫外線光源5之發光同時作低速驅動，而將濾器3以設定時間低速旋轉進行說明，但不限於此，濾器用馬達30之低速驅動可與紫外線光源5之發光非為同時。亦即，濾器用馬達30之低速驅動可與紫外線光源5之發光非為同時，而自發光而始經過短暫時間再開始，濾器用馬達30之低速驅動時間也不限於設定時間，也可為設定時間中之一部分的時間。以設定時間中之一部分的時間濾器用馬達30作低速驅動的情形下，停止狀態與低速驅動狀態可間歇地進行。 　　[0036] 以上之各實施方式中，濾器3之高速旋轉係指800rpm以上。 　　濾器3之低速旋轉係指未達800rpm。 　　又，濾器3較佳的是在油附著之面塗佈有光觸媒者。 　　以上之各實施方式，係在排煙罩2中設置整流板24而形成流路25，但也可不設置整流板而在排煙罩2內具有流路25。 　　如第3至第6實施方式般，旋轉濾器3而照射紫外線類型之抽油煙機的情形下，紫外線光源5之紫外線的照射區域不限於濾器3之下面全面，也可為至少從濾器3之緣部以至濾器3之旋轉中心為止經照射之區域者。於此一情形下，紫外線照射中係藉由旋轉濾器3而對濾器3之下面全面照射紫外線。[0015] The first embodiment of the present invention will be described with reference to FIG. 1, FIG. 2, and FIG. 3.　　 Figure 1 is a cross-sectional view of the range hood, Figure 2 is an enlarged view of the filter mounting part, and Figure 3 is an explanatory view of the operation operation part and the control part.　　The range hood 1 is provided with: an exhaust hood 2, a filter 3, a blower 4, and an ultraviolet light source 5. The fume exhaust hood 2 is a low-height rectangular box shape formed by a top panel 20, a peripheral panel 21, and a lower panel 22. The bottom plate 22 has a concave portion 23 that is recessed toward the top plate 20, a rectifying plate 24 is installed in the concave portion 23, and a flow path 25 is formed by the rectifying plate 24 and the concave portion 23. The lower part of the flow path 25 is opened toward the bottom of the exhaust hood 2, and the upper part of the flow path 25 is opened toward the upper side of the exhaust hood 2 at the opening 26. The 　　 filter 3 is provided in the flow path 25, and the filter 3 is opposed to the opening 26. Thereby, the oil fume and the like flowing into the flow path 25 will flow through the filter 3 to the opening 26. The filter 3 of the range hood 1 of this embodiment is rotationally driven by the motor 30 for the filter.　　[0016] The installation embodiment of the filter 3 will be described with reference to Fig. 2. A plate 31 is installed in the opening 26 of the fume exhaust hood 2. The plate 31 has a hole 31a having a diameter slightly smaller than the outer diameter of the filter 3, and a motor mounting plate 32 is installed on the plate 31 so as to straddle the center of the hole 31a. The width of the motor mounting plate 32 is significantly narrower than the hole diameter of the hole 31a, so that it will not become an obstacle to the air flowing through the hole 31a. A filter motor 30 is mounted on the upper surface of the motor mounting plate 32. The rotating shaft 30a of the filter motor 30 passes through the hole 31a of the plate 31 and protrudes to the flow path 25 of the exhaust hood 2, and the filter 3 is mounted on the protruding part. On the lower surface of the "plate 31", a ring-shaped flow volume retention member 33 is installed to surround the filter 3. The flow volume retaining member 33 is formed by a cylindrical body 33a having a larger inner diameter than the outer diameter of the filter 3, and an upward hook-shaped piece 33b continuously installed at the lower end of the inner peripheral surface of the cylindrical body 33a, and has a ring shape and The lower part has a flow volume retaining portion 33c that is continuous in the circumferential direction and opens upward.　　[0017] As shown in FIG. 1, the blower 4 has a housing 41 provided in the blower case 40, a fan 42 provided in the housing 41, and a fan motor 43 for rotating the fan 42. The air supply box 40 is installed on the top panel 20 of the exhaust hood 2, and the suction hole 41a of the housing 41 is connected to the opening 26 of the exhaust hood 2. The exhaust hole 41b of the housing 41 is in communication with the exhaust duct 44. "Therefore, by rotating the fan 42 with the fan motor 43, the oily smoke generated during heating and conditioning can be trapped in the exhaust hood 2 in the flow path 25. The trapped oil fume and the like are attached to the filter 3 to be removed, and the oil fume is discharged from the exhaust duct 44 as oil-free air.　　The ultraviolet light source 5 irradiates the oil adhesion surface of the filter 3 with ultraviolet rays. As the ultraviolet light source 5, an ultraviolet lamp, LED, mercury lamp, etc. can be used.　　[0018] In this embodiment, as shown in FIG. 2, a plurality of ultraviolet lamps are installed as ultraviolet light sources 5 at intervals in the circumferential direction on the inner peripheral surface of the cylindrical body 33a of the flow volume retention member 33.　　Therefore, the ultraviolet light source 5 does not constitute an obstacle to the oily smoke flowing toward the filter 3.　　Ultraviolet light source 5 (ultraviolet lamp) emits ultraviolet light obliquely upward, and can irradiate ultraviolet light on the entire surface of the lower surface of the filter 3 (the entire surface of the oil adhesion surface). In addition, the ultraviolet lamp only needs to be able to irradiate the entire area under the filter 3. Therefore, if one ultraviolet lamp can irradiate the entire area under the filter 3, even one ultraviolet lamp is feasible.　　[0019] As shown in Fig. 1, on the peripheral panel 21 of the exhaust hood 2, an operation operation part 6 for operating the range hood 1 is installed.　　The fume exhaust hood 2 is provided with a control unit 7. The control unit 7 drives and controls the fan motor 43 in accordance with instructions from the operation operation unit 6, and controls the turning on and off of the ultraviolet light source 5.　　[0020] As shown in FIG. 3, the operation operation unit 6 includes a strong operation switch 60, a middle operation switch 61, a weak operation switch 62, and a stop switch 63. The strong operation switch 60 is operated when the heating conditioning of the heating conditioner starts, and outputs a strong operation command to the control unit 7. The intermediate operation switch 61 is operated when the heating conditioning of the heating conditioner starts, and outputs an intermediate operation command to the control unit 7. The weak operation switch 62 is operated when the heating conditioning of the heating conditioner starts, and outputs a weak operation command to the control unit 7.　　 Also, if different operation switches are operated during heating conditioning, different operation commands can be output. The 　　 stop switch 63 is operated when the heating conditioning of the heating conditioner is completed, and outputs an operation stop command 7 to the control unit 7. The "control unit 7" has an operation control unit 70 and a filter washing control unit 71.　　[0021] The operation control unit 70, if a strong operation command is input, drives the fan of the blower 4 with a motor 43 at a high speed to rotate the fan 42 of the blower 4 at a high speed, so that the range hood 1 is forced to operate. If the middle operation command is input, the fan motor 43 is driven at a middle speed to rotate the fan 42 of the blower 4 at a middle speed, so that the range hood 1 is operated in the middle. If the weak operation command is input, the fan motor 43 is driven at a low speed to rotate the fan 42 of the blower 4 at a low speed, so that the range hood 1 is operated weakly. The operation control unit 70 stops the drive of the fan motor 43 and stops the rotation of the fan 42 of the blower 4 if there is an operation stop command input in the state of the range hood 1 in the strong operation, the medium operation, and the weak operation. Machine 1 stops. [0022] When the filter cleaning control unit 71 receives an operation stop command input while the range hood 1 is in operation, it will turn on the ultraviolet light source 5 at a set time and drive the fan motor 43 at the set time. The fan 42 of the blower 4 is rotated at a set time.　　 Then, after the set time has elapsed since the operation stop command was input, the ultraviolet light source 5 is turned off, the driving of the fan motor 43 is stopped, and the rotation of the fan 42 of the blower 4 is stopped.　　The set time refers to the time when the operation stop command is input and the oil attached to the filter 3 can be decomposed and removed. In addition, it can also be set so that when there is an operation stop command input, the operation control unit 70 does not stop the drive of the fan motor 43 and is set to a continuous driving state, and the filter cleaning control unit 71 when an operation stop command is input, the blower The fan 42 of 4 rotates at a set time. [0023] In other words, the control unit 7 turns on the ultraviolet light source 5 for a set time after the heating conditioner finishes heating and the operation state of the range hood 1 stops, and drives the fan motor 43 while the ultraviolet light source 5 is on. The fan 42 of the blower 4 is rotated. When it is set to operate and stop the range hood 1 in conjunction with the heating conditioner, the fan motor 43 is rotated by the heating conditioner ON command, and the fan motor 43 is temporarily stopped by the OFF command, and click The ultraviolet light source 5 is turned on, and the fan motor 43 is driven again, thereby rotating the fan 42 of the blower 4 when the ultraviolet light source 5 is turned on. In addition, the OFF command may not stop the fan motor 43, but may continue to rotate. In this way, when the heating conditioning of the heating conditioner is completed, the operation of the range hood 1 in the operating state is stopped and the oil smoke does not flow into the flow path 25 of the fume hood 2, the filter 3 is irradiated with ultraviolet rays to decompose and remove the attached oil Therefore, ultraviolet rays can be efficiently irradiated to the oil adhesion surface of the filter 3 regardless of the oily smoke flowing in the exhaust hood 2.　　[0024] Therefore, the oil adhering to the filter 3 has an excellent decomposition ability, and the filter 3 can be cleanly washed.　　 Furthermore, when the filter 3 is irradiated with ultraviolet rays to decompose the oil, the fan 42 of the blower 4 is rotating, so the foul odor and ozone generated when the oil is decomposed can be discharged by the blower 4.　　 Therefore, it can be formed into a range hood that does not feel bad smell for indoor people and does not fill the room with ozone.　　[0025] Next, the second embodiment of the present invention will be described. The configuration of the range hood 1 is the same as that of the range hood 1 of the first embodiment shown in Figs. 1 and 2, and the control unit 7 is different from the control unit 7 of the first embodiment. The "control unit 7" has an operation control unit 70 and a filter washing control unit 71 like the control unit 7 shown in FIG. 3. When the operation stop command is input, the filter cleaning control unit 71 emits the ultraviolet light source 5 for a set time as in the filter cleaning control unit 71 of the first embodiment, and drives the fan motor 43 to rotate the fan 42 of the blower 4 .　　 After a set time has elapsed since the operation stop command is input, the ultraviolet light source 5 is turned off, and the fan motor 43 is continuously driven. After a certain period of time, the drive of the fan motor 43 is stopped and the rotation of the fan 42 of the blower 4 is stopped.　　[0026] In other words, the control unit 7 causes the ultraviolet light source 5 to emit light and rotates the fan 42 of the blower 4 after the range hood 1 is in operation and stopped. The control unit 7 turns off the ultraviolet light source 5 after the set time has elapsed after the operation is stopped, and the fan 42 of the blower 4 continues to rotate, and after a certain period of time has passed, the rotation of the fan 42 of the blower 4 is stopped. The control unit 7 of the second embodiment controls the ultraviolet light source 5 and the fan motor 43 in this way, so when the filter 3 is irradiated with ultraviolet rays to decompose the oil, the offensive odor and ozone generated during and after ultraviolet irradiation It is discharged by the blower 4.　　Therefore, bad smell and ozone can be discharged surely. "As it is, in the first and second embodiments, since the filter motor 30 does not operate, the filter motor 30 may not be provided. That is, the range hood of the first and second embodiments may be a range hood provided with a filter 3 that can be rotated by a filter motor 30, or a range hood that does not have a filter motor 30 and is provided with a non-rotatable filter 3 range hoods.　　[0027] Next, a third embodiment of the present invention will be described. The constitution of the range hood 1 is the same as that of the range hood 1 of the first embodiment shown in Figs. 1 and 2, and the control unit 7 is different from the control unit 7 of the first embodiment. As shown in FIG. 4, the "control unit 7" has an operation control unit 70 and a filter washing control unit 71. The "operation control unit 70" is the same as the operation control unit 70 of the first embodiment. The filter cleaning control unit 71 controls the filter motor 30 as follows before controlling the ultraviolet light source 5 and the fan motor 43 as in the first embodiment or the second embodiment. In the state of the operation command input, if there is an operation stop command input, before the ultraviolet light source 5 emits light and the fan motor 43 is driven, the filter motor 30 is driven at a high speed for a specific time and the filter 3 is driven at a high speed for a specific time. Spin.　　[0028] After a certain time has passed, the drive of the filter motor 30 is stopped and the rotation of the filter 3 is stopped.　　 In other words, before the ultraviolet irradiation, the filter 3 is rotated at a high speed for a specific time. After a specific time has passed since the operation stop command was input, the ultraviolet light source 5 and the fan motor 43 are controlled as in the first embodiment or the second embodiment. Furthermore, after a certain time has passed, the drive of the filter motor 30 can be continued and the rotation of the filter 3 can be continued.　　[0029] In this case, by rotating the filter 3 at a high speed before irradiating the filter 3 with ultraviolet rays, a part of the oil adhering to the filter 3 will scatter around the filter 3 and be removed from the filter 3.　　 Therefore, the oil remaining in the filter 3 can be decomposed by ultraviolet rays, and the oil adhering to the filter 3 can be easily decomposed by ultraviolet rays. In addition, since a large amount of oil is removed and the filter 3 is irradiated with ultraviolet rays in a state where only a minimum amount of oil is attached, the ultraviolet ray irradiation time can be shortened.　　The oil scattered around the filter 3 is accumulated in the flow volume retention portion 33c of the flow volume retention member 33, so that it does not cause the fume exhaust hood 2 to be dirty.　　[0030] Next, the fourth embodiment of the present invention will be described. The configuration of the range hood 1 is the same as that of the range hood 1 of the first embodiment shown in Figs. 1 and 2, and the control unit 7 is different from the control unit 7 of the first embodiment. As shown in FIG. 4, the "control unit 7" has an operation control unit 70 and a filter washing control unit 71. The "operation control unit 70" is the same as the operation control unit 70 of the first embodiment. The "filter washing control unit 71" controls the ultraviolet light source 5 and the fan motor 43 as in the first embodiment or the second embodiment. At the same time, the filter motor 30 is controlled as follows. In the state where the operation command is being input, if there is an operation stop command input, after the UV light source 5 is turned off after the light-emitting setting time of the ultraviolet light source 5 has elapsed, the filter motor 30 is driven at a high speed for a certain time and the filter 3 is high Spin. After a certain period of time has passed, the drive of the filter motor 30 is stopped and the rotation of the filter 3 is stopped.　　[0031] In this way, after the filter 3 is irradiated with ultraviolet rays, the filter 3 is rotated at a high speed, and the water generated by the decomposition of the oil attached to the filter 3 will scatter around the filter 3 and be removed from the filter 3.　　 In other words, because the oil attached to the filter 3 is decomposed into water and carbon dioxide by ultraviolet radiation, by rotating the filter 3 at a high speed, the water on the filter 3 can be scattered around by centrifugal force and removed.　　The carbon dioxide is discharged by the blower 4. The water scattered around the filter 3 is accumulated in the flow volume retention portion 33c of the flow volume retention member 33, so the water does not flow into the exhaust hood 2. Also, similar to the third embodiment, it is also possible to use the filter motor before the ultraviolet light source 5 emits light and the fan motor 43 is driven if there is an operation stop command input while the operation command is being input. 30 is driven at a high speed for a specific time and the filter 3 is rotated at a high speed for a specific time.　　[0032] Next, the fifth embodiment of the present invention will be described. The constitution of the range hood 1 is the same as that of the range hood 1 of the first embodiment shown in Figs. 1 and 2, and the control unit 7 is different from the control unit 7 of the first embodiment. As shown in FIG. 4, the "control unit 7" has an operation control unit 70 and a filter washing control unit 71. The "operation control unit 70" is the same as the operation control unit 70 of the first embodiment. The "filter washing control unit 71" controls the ultraviolet light source 5 and the fan motor 43 as in the first embodiment or the second embodiment. At the same time, the filter motor 30 is controlled as follows. In the state of operation command input, if there is an operation stop command input, at the same time as the ultraviolet light source 5 emits light, the filter motor 30 is driven at a high speed with the same setting time as the ultraviolet light source 5's light emission time, and the filter 3 is set to Time rotates at high speed. After the set time has elapsed, the drive of the filter motor 30 is stopped and the rotation of the filter 3 is stopped. In other words, the filter 3 is rotated at a high speed during the irradiation of ultraviolet rays.　　[0033] In this way, by irradiating the filter 3 with ultraviolet rays and rotating the filter 3 at a high speed, the oil adhering to the filter 3 has many chances to come into contact with the oxygen required to decompose the oil, and the oil can be efficiently decomposed. Also, similar to the third embodiment, it is also possible to use the filter motor before the ultraviolet light source 5 emits light and the fan motor 43 is driven if there is an operation stop command input while the operation command is being input. 30 is driven at a high speed for a specific time and the filter 3 is rotated at a high speed for a specific time. Also, similar to the fourth embodiment, it is also possible that if there is an operation stop command input in the state of the operation command input, after the ultraviolet light source 5 is set to emit light for a time and the ultraviolet light source 5 is turned off, the filter is used The motor 30 is driven at a high speed for a certain time and the filter 3 is rotated at a high speed for a certain time. It is also possible to stop the drive of the filter motor 30 to stop the rotation of the filter 3 after a certain period of time has passed. In addition, the above is the high-speed driving of the filter motor 30 and the ultraviolet light source 5 at the same time, and the filter 3 is rotated at a high speed at a set time, but it is not limited to this, and the high-speed driving of the filter motor 30 may not be the same as the ultraviolet light source 5. It shines at the same time. That is, the high-speed driving of the filter motor 30 can be different from the light emission of the ultraviolet light source 5, and a short time elapses from the light-emission, and the high-speed driving time of the filter motor 30 is not limited to the set time, but can also be set A part of time. When the motor 30 for the time filter is driven at a high speed by a part of the set time, the stopped state and the high-speed drive state can be performed intermittently.　　[0034] Next, the sixth embodiment of the present invention will be described. The constitution of the range hood 1 is the same as that of the range hood 1 of the first embodiment shown in Figs. 1 and 2, and the control unit 7 is different from the control unit 7 of the first embodiment. As shown in FIG. 4, the "control unit 7" has an operation control unit 70 and a filter washing control unit 71. The "operation control unit 70" is the same as the operation control unit 70 of the first embodiment. The "filter washing control unit 71" controls the ultraviolet light source 5 and the fan motor 43 as in the first embodiment or the second embodiment. At the same time, the filter motor 30 is controlled as follows. In the state of operation command input, if the operation stop command is input, at the same time as the ultraviolet light source 5 emits light, the filter motor 30 is driven at a low speed with the same setting time as the ultraviolet light source 5's light emission time, and the filter 3 is driven at the set time Rotate at low speed. In other words, during the ultraviolet irradiation, the filter 3 is rotated at a low speed.　　 After the set time has elapsed, the drive of the filter motor 30 is stopped and the rotation of the filter 3 is stopped.　　 It is also possible to continue the drive of the filter motor 30 to continue the rotation of the filter 3 after the set time has elapsed.　　[0035] In this way, when the filter 3 is irradiated with ultraviolet rays, by rotating the filter 3 at a low speed, the amount of ultraviolet rays irradiated per unit area of the filter 3 is increased, and the ability to decompose the oil adhering to the filter 3 is excellent.　　 Therefore, the oil adhering to the filter 3 can be sufficiently decomposed and the oil can be reliably removed from the filter 3. Also, as in the third embodiment, it is possible to use the filter motor 30 before the ultraviolet light source 5 emits light and the fan motor 43 is driven if the operation stop command is input while the operation command is being input. The filter 3 is driven at a high speed for a specific time and the filter 3 is rotated at a high speed for a specific time. Also, as in the fourth embodiment, if the operation stop command is input while the operation command is being input, after the UV light source 5 is turned off after the light emission setting time of the ultraviolet light source 5 has elapsed, the filter motor 30 is driven to a high speed for a certain period of time. The filter 3 is driven to rotate at a high speed for a certain period of time. After a certain period of time has elapsed, the drive of the filter motor 30 can be stopped and the rotation of the filter 3 can be stopped. Furthermore, the above description is that the filter motor 30 and the ultraviolet light source 5 emit light at a low speed at the same time, and the filter 3 is rotated at a low speed for a set time, but it is not limited to this. The low speed drive of the filter motor 30 can be combined with the ultraviolet light source 5 The light is not at the same time. That is, the low-speed driving of the filter motor 30 may not be simultaneous with the light emission of the ultraviolet light source 5, and the self-emission will start after a short time. The low-speed driving time of the filter motor 30 is not limited to the set time, but can also be set A part of time. In a case where the time filter motor 30 is driven at a low speed by a part of the set time, the stopped state and the low speed drive state can be performed intermittently.　　[0036] In the above embodiments, the high-speed rotation of the filter 3 refers to 800 rpm or more.　　The low-speed rotation of filter 3 means that it does not reach 800rpm.　　 Furthermore, the filter 3 is preferably one coated with a photocatalyst on the surface where the oil adheres. "In each of the above embodiments, the flow path 25 is formed by providing the flow rectifying plate 24 in the fume hood 2, but the flow path 25 may be provided in the fume hood 2 without providing the flow rectifying plate. As in the third to sixth embodiments, in the case of rotating the filter 3 to irradiate the ultraviolet type range hood, the ultraviolet irradiated area of the ultraviolet light source 5 is not limited to the entire bottom surface of the filter 3, and may be at least from the edge of the filter 3. The area that has been irradiated up to the center of rotation of the filter 3. In this case, in the ultraviolet irradiation, the filter 3 is rotated to irradiate the entire underside of the filter 3 with ultraviolet rays.
