Description
本發明係有關一種雙背吸式排油煙機,尤指一種可有效排除油煙,以適用於工廠、實驗室及廚房者。 The invention relates to a double back suction type range hood, in particular to a method which can effectively remove soot for use in factories, laboratories and kitchens.
為了改善傳統型排油煙機排油煙效率不良之問題,本發明人曾利用氣體動力學原理,研發出一種具有「氣簾」之排油煙機,以克服上述問題。然而,能產生二維氣簾之排油煙機必須同時安裝吹氣及排氣裝置,在更換或安裝作業上相當麻煩,相對的將增加設備及人力作業成本。 In order to improve the problem of poor exhaust efficiency of the conventional exhaust hood, the inventors have developed a range hood having a "air curtain" using the principle of gas dynamics to overcome the above problems. However, the range hood that can produce a two-dimensional air curtain must be equipped with a blowing and exhausting device at the same time, which is quite troublesome in replacement or installation work, and relatively increases the equipment and labor costs.
基於上述問題,本發明人進一步改良出另一種型式之排油煙機,其結構主要包括一吸氣罩、一左立板及一右立板,其中,左、右立板分別結合於吸氣罩的左側面及右側面之下方;而吸氣罩係為概略呈長方形的殼體,吸氣罩的內部設有一集風箱,集風箱的底面設有一狹長抽氣口,以向上抽氣。 Based on the above problems, the inventors further improved another type of range hood, the structure of which mainly includes a suction hood, a left vertical plate and a right vertical plate, wherein the left and right vertical plates are respectively coupled to the suction hood The suction hood is a substantially rectangular casing, and the inside of the suction hood is provided with a collecting box, and the bottom of the collecting box is provided with a narrow suction port for pumping upward.
在實際使用時,上述結構確實可以有效排除油煙。但由於該結構的狹長抽氣口位於集風箱的底面,其必需藉由很長的左立板及右立板的阻隔作用,才能在狹長抽氣口抽取上升油煙的過程中,有效防止側向擾動氣流的影響,以達到預定之排煙效果。然而,當較長的左立板及右立板分別結合在吸氣罩的左側面及右側面下方時,其整體感覺較有壓迫感。 In actual use, the above structure can effectively eliminate soot. However, since the narrow suction port of the structure is located on the bottom surface of the wind collecting box, it is necessary to prevent the lateral disturbance in the process of extracting the rising soot in the narrow suction port by the long blocking action of the left vertical plate and the right vertical plate. The effect of the airflow to achieve the desired exhaust effect. However, when the long left vertical plate and the right vertical plate are respectively combined under the left side surface and the right side surface of the suction hood, the overall feeling is more oppressive.
有鑑於此,為了提供一種有別於習用技術之結構,並改善上述之缺點,發明人積多年的經驗及不斷的研發改進,遂有本發明之產生。 In view of the above, in order to provide a structure different from the conventional technology and to improve the above disadvantages, the inventors have accumulated many years of experience and continuous development and improvement, and the present invention has been produced.

本發明雙背吸式排油煙機係在一集風箱前端面之上半部及下半部分別設有橫向且呈狹長狀延伸之至少一第一抽氣口及至少一第二抽氣口,其中,至少一第一抽氣口平行至少一第二抽氣口,至少一第一抽氣口與至少一第二抽氣口連通至少一抽氣裝置。至少一抽氣裝置抽氣時,同一時間通過至少一第二抽氣口之總氣體流量大於通過至少一第一抽氣口之總氣體流量。藉以在至少一第二抽氣口抽取大部份的油煙之後,再以至少一第一抽氣口將極少部份向上流動之油煙完全抽除。 The double-back suction-type range hood of the present invention is provided with at least one first suction port and at least one second suction port extending transversely and in a narrow shape in the upper half and the lower half of the front end surface of the wind turbine box, wherein The at least one first air suction port is parallel to the at least one second air suction port, and the at least one first air suction port is connected to the at least one second air suction port to connect at least one air suction device. When at least one of the air suction devices is pumping, the total gas flow rate through the at least one second air suction port at the same time is greater than the total gas flow rate through the at least one first air suction port. After extracting a large portion of the soot at the at least one second suction port, the at least one first suction port completely removes a portion of the upwardly flowing soot.
請參閱第1~3圖所示,其為本發明雙背吸式排油煙機1之第一實施例,係包括一集風箱2及一抽氣裝置3。實施時,以使用者面對集風箱2之相對位置界定出該集風箱2之左側及右側,以集風箱2接近使用者之一側界定為前端面,並以反向於集風箱2之前端面且遠離使用者之一側界定為後端面。 Referring to Figures 1 to 3, which is a first embodiment of the double-back suction range hood 1 of the present invention, it comprises a wind collecting box 2 and an air extracting device 3. In the implementation, the left side and the right side of the wind collecting box 2 are defined by the relative position of the user facing the wind collecting box 2, and the front side of the wind collecting box 2 is defined as a front end surface, and is opposite to the collecting wind. The front end face of the case 2 and one side away from the user are defined as a rear end face.
該集風箱2包括呈倒L形配置之一水平頂部21及一直立部22,其中,水平頂部21及直立部22之內部具有一容納空間23。水平頂部21之頂面設有一排氣口24,排氣口24內設有一鼓風機,該鼓風機做為抽氣裝置 3。而直立部22之前端面上半部具有橫向且呈狹長狀間隔排列延伸之複數個圓孔,該圓孔做為第一抽氣口221;直立部22之前端面下半部具有橫向且呈狹長狀延伸之一個長條形孔,該長條形孔做為第二抽氣口222。上述複數個第一抽氣口221平行該第二抽氣口222,且第一抽氣口221、第二抽氣口222經由集風箱2之容納空間23與抽氣裝置3相互連通。另,直立部22之底部具有一油槽225,油槽225與容納空間23連通,供容納廢油。 The windbox 2 includes a horizontal top portion 21 and an upright portion 22 in an inverted L configuration, wherein the interior of the horizontal top portion 21 and the upright portion 22 has a receiving space 23. The top surface of the horizontal top portion 21 is provided with an exhaust port 24, and a blower is disposed in the exhaust port 24, and the blower is used as an air extracting device. 3. The upper half of the front end portion of the upright portion 22 has a plurality of circular holes extending in a laterally and narrowly spaced interval, and the circular hole serves as a first air suction port 221; the lower half of the front end portion of the upright portion 22 has a lateral and elongated shape. One of the elongated holes is used as the second suction port 222. The plurality of first air suction ports 221 are parallel to the second air suction port 222, and the first air suction port 221 and the second air suction port 222 communicate with each other through the accommodating space 23 of the wind collecting box 2 and the air extracting device 3. In addition, the bottom of the upright portion 22 has an oil groove 225, and the oil groove 225 communicates with the accommodating space 23 for accommodating waste oil.
上述第二抽氣口222之通孔面積大於複數個第一抽氣口221之總通孔面積。一般而言,由於集風箱2之排氣口24位於水平頂部21之頂面,而複數個第一抽氣口221接近排氣口21,第二抽氣口222遠離排氣口24,當抽氣裝置3運轉時,同一時間通過第二抽氣口222之總氣體流量會小於通過至少一第一抽氣口221之總氣體流量。但由於本發明之第二抽氣口222之通孔面積大於複數個第一抽氣口221之總通孔面積,基於如第4圖所示有關流體力學之理論,其在同一流體流量通過不同之通孔面積時,由於壓力損失之不同,將使得同一時間通過第二抽氣口222之總氣體流量大於通過該至少一第一抽氣口221之總氣體流量。 The through hole area of the second suction port 222 is larger than the total through hole area of the plurality of first suction ports 221 . Generally, since the exhaust port 24 of the wind collecting box 2 is located at the top surface of the horizontal top portion 21, and the plurality of first air extracting ports 221 are close to the exhaust port 21, the second air extracting port 222 is away from the exhaust port 24, when pumping When the device 3 is in operation, the total gas flow rate through the second suction port 222 at the same time may be less than the total gas flow rate through the at least one first suction port 221 . However, since the through hole area of the second suction port 222 of the present invention is larger than the total through hole area of the plurality of first suction ports 221, based on the theory of fluid mechanics as shown in FIG. 4, the same fluid flow passes through different passages. When the hole area is different, the total gas flow rate passing through the second suction port 222 at the same time is greater than the total gas flow rate passing through the at least one first suction port 221 due to the difference in pressure loss.
藉此,如第5圖所示,當使用者在使用一鍋爐9並產生油煙時,經由抽氣裝置3之運轉,即可以具有大抽氣量之長條形第二抽氣口222抽取大部份之油煙,再以複數個第一抽氣口221將極少部份向上流動之油煙完全抽除,並由排氣口24向外排出。 Thereby, as shown in FIG. 5, when the user uses a boiler 9 and generates soot, the operation of the air extracting device 3, that is, the long strip-shaped second air extracting port 222 having a large pumping amount is extracted. The soot is completely removed by a plurality of first suction ports 221, and is exhausted by the exhaust port 24.
實施時,上述第一抽氣口221亦可如第6、7圖所示,係為方形、長方形之類具有不同幾何形狀之穿孔。第二抽氣口222亦可為圓孔、方形孔或長方形孔之類具有不同幾何形狀之穿孔,且複數個第二抽氣口222係 以橫向且呈狹長狀間隔排列。而抽氣裝置3亦可設有二個,且分別連通至少一第一抽氣口221及至少一第二抽氣口222,以藉由不同抽氣量之控制,使同一時間通過至少一第二抽氣口222之總氣體流量大於通過至少一第一抽氣口221之總氣體流量。 In the implementation, the first air suction port 221 may also be a square, rectangular or the like having different geometric shapes as shown in FIGS. The second air suction port 222 can also be a circular hole, a square hole or a rectangular hole or the like having different geometric shapes, and the plurality of second air suction ports 222 are Arranged in a laterally and narrowly spaced interval. The air extracting device 3 can also be provided with two, and respectively connected to the at least one first air extracting port 221 and the at least one second air extracting port 222 to pass the at least one second air extracting port at the same time by the control of different air pumping amounts. The total gas flow rate of 222 is greater than the total gas flow rate through at least one first extraction port 221 .
請參閱第8~10圖所示,其為本發明雙背吸式排油煙機1之第二實施例,其與第一實施例不同之處在於:本發明更包括一第一蓋板4、一第二蓋板5及一連接件6,其中,集風箱2之直立部22之前端面之複數個第一抽氣口221兩側分別設有一第一導軌223,第二抽氣口222兩側分別設有一第二導軌224,藉以使第一蓋板4以可上、下移動之方式活動定位於至少一第一抽氣口221之前端面上,並使第二蓋板5以可上、下移動之方式活動定位於至少一第二抽氣口22之前端面上。 Referring to FIGS. 8-10, which is a second embodiment of the double-back suction range hood 1 of the present invention, which is different from the first embodiment in that the present invention further includes a first cover 4, A second cover plate 5 and a connecting member 6 are respectively disposed on the two sides of the plurality of first air suction ports 221 of the front end surface of the upright portion 22 of the wind collecting box 2, respectively, and a first guiding rail 223 is respectively disposed on the two sides of the second air extracting port 222 A second guide rail 224 is disposed, so that the first cover plate 4 is movably positioned on the front end surface of the at least one first air suction port 221 in an upwardly and downwardly movable manner, and the second cover plate 5 is movable up and down. The mode activity is positioned on the front end surface of the at least one second air suction port 22.
另,第一蓋板4之板面上設有呈狹長狀延伸之至少一第三抽氣口41,該第三抽氣口41係為圓孔、方形孔或長方形孔之類具有不同幾何形狀之穿孔,當第一蓋板4蓋合於至少一第一抽氣口221之前端面上時,至少一第三抽氣口41連通至少一第一抽氣口221,其同一時間通過第二抽氣口222之總氣體流量大於通過該至少一第一抽氣口221及至少一第三抽氣口41之總氣體流量。而該連接件6之上、下兩端係分別連接第一蓋板4及第二蓋板5,以同時移動第一蓋板4及第二蓋板5。 In addition, at least one third air suction port 41 extending in a narrow shape is disposed on the surface of the first cover plate 4, and the third air suction port 41 is a hole having different geometric shapes such as a circular hole, a square hole or a rectangular hole. When the first cover 4 covers the front end surface of the at least one first air suction port 221, the at least one third air suction port 41 communicates with the at least one first air suction port 221, and the total gas passing through the second air suction port 222 at the same time. The flow rate is greater than the total gas flow rate through the at least one first suction port 221 and the at least one third suction port 41. The upper and lower ends of the connecting member 6 are respectively connected to the first cover 4 and the second cover 5 to simultaneously move the first cover 4 and the second cover 5.
藉此,當第一蓋板4蓋合於至少一第一抽氣口221之前端面上,且第二抽氣口222呈開放狀態時,即可以第二抽氣口222抽取大部份之油煙,再以至少一第三抽氣口41將極少部份向上流動之油煙完全抽除;而當第二蓋板5蓋合於第二抽氣口222之前端面上,且至少一第一抽氣口221呈開 放狀態時,則可以使用在例如蒸籠之類的高鍋具之烹煮上,以直接抽取較高鍋爐所產生之油煙。 Thereby, when the first cover 4 covers the front end surface of the at least one first air suction port 221, and the second air suction port 222 is in an open state, the second air suction port 222 can extract most of the oil smoke, and then At least one third air suction port 41 completely removes a portion of the upwardly flowing soot; and when the second cover plate 5 covers the front end surface of the second air suction port 222, and at least one first air suction port 221 is opened. In the state of being placed, it can be used in the cooking of high pots such as steamers to directly extract the fumes generated by the higher boilers.
請參閱第11圖所示,其為本發明雙背吸式排油煙機1之第三實施例,其與第一實施例及第二實施例不同之處在於:該集風箱2之水平頂部21之底面設有呈狹長狀延伸之至少一吹氣口211,至少一吹氣口211位於直立部22前端面之前方,且至少一吹氣口221平行至少一第一抽氣口211及至少一第二抽氣口222,藉以形成向下吹送之氣流,以防止可能之少量油煙經由集風箱2前端面之下方向外逸出。水平頂部21之左側面下方結合一左立板212,以使左立板212由左側面下方向下延伸,左立板212之右側邊緣結合一左弧形導引部213;而水平頂部21之右側面下方結合一右立板214,右立板214由右側面下方向下延伸,右立板214之左側邊緣結合一右弧形導引部215,藉以產生集風箱2左、右兩側之氣流阻擋作用,並使集風箱2前端及下方之空氣能順暢的進入,以形成補氣之效果。另,水平頂部21之底面兩側分別設有相互對稱之一倒三角形左頂板216及一倒三角形右頂板217,左頂板216位於左弧形導引部213與抽氣口24之間,右頂板217位於右弧形導引部215與抽氣口24之間,具體而言,左頂板216之頂邊向上鄰近水平頂部21之底面左側,左頂板216之左側邊向左鄰近左立板212之右側面;而右頂板217之頂邊向上鄰近水平頂部21之底面右側,右頂板217之右側邊向右鄰近右立板214之左側面。且左頂板216之頂邊與右頂板217之頂邊分別與吹氣口221平行,並位於吹氣口221之前端,藉以避免油煙污染物經由水平頂部21與左、右立板(212、214)之交界處向外洩漏。 Please refer to FIG. 11 , which is a third embodiment of the double-back suction range hood 1 of the present invention, which is different from the first embodiment and the second embodiment in that the horizontal top of the wind collecting box 2 is The bottom surface of the bottom surface 21 is provided with at least one air blowing port 211 extending in a narrow shape, at least one air blowing port 211 is located in front of the front end surface of the upright portion 22, and at least one air blowing port 221 is parallel to at least one first air extracting port 211 and at least one second pumping port.
