Description
本發明關於一種吹風機減低噪音結構，主要指一種可減少吹風機動作進氣產生噪音結構。The invention relates to a noise reduction structure of a hair dryer, which mainly relates to a noise structure which can reduce the noise generated by the action of the hair dryer.
吹風機為人們吹乾頭髮必須的電器設備之一，如第十一圖所示為習知吹風機結構之一，主要具外殼1'、電熱機構2’、風扇3’組件，並該外殼1’具容室11’以容置電熱機構2’、風扇3’，並於前、後端分別設置出風口12’、入風口13’，並於入風口13’位置設置柵蓋14’，又該電熱機構2’及風扇3’分別設於容室11’前、後方位置，使得風扇3’動作可將外界氣流由入風口13’導入容室11’內，並經由電熱機構2’加熱產生氣流再由出風口12’導出。The hair dryer is one of the electrical equipment necessary for people to dry their hair. As shown in FIG. 11 , it is one of the conventional hair dryer structures, which mainly has a casing 1 ′, an electric heating mechanism 2 ′, a fan 3 ′ component, and the casing 1 ′ The chamber 11' accommodates the electric heating mechanism 2' and the fan 3', and is respectively provided with an air outlet 12' and an air inlet 13' at the front and the rear ends, and a grid cover 14' is disposed at the position of the air inlet 13'. The mechanism 2' and the fan 3' are respectively disposed at the front and rear positions of the chamber 11', so that the fan 3' acts to introduce the external airflow into the chamber 11' from the air inlet 13', and is heated by the electric heating mechanism 2' to generate airflow. It is derived from the air outlet 12'.
然而第十一圖箭頭所示，前述結構當外界大範圍之氣流強制由直徑較小之入風口13’導入時其氣流將直接衝擊出風口13’周緣，造成如圖式a位置產生明顯進氣位置撞擊噪音，且導入容室11’之氣流亦產生亂流並撞緊外殼1’內壁，因而亦造成吹風機噪音增大缺失，且該吹風機使用時係位於靠近人體頭部位置，將造成使用不舒適缺失，又對美容院等營業場所人員而言更易造成影響聽力之職業傷害。However, as indicated by the arrow in the eleventh figure, when the outside airflow is forced to be introduced by the smaller diameter air inlet 13', the airflow will directly hit the periphery of the air outlet 13', resulting in a significant intake of air as shown in the figure a. The position impact noise, and the airflow introduced into the chamber 11' also causes turbulence and collides against the inner wall of the outer casing 1', thereby causing a lack of noise increase of the blower, and the blower is located close to the head of the human body, which will cause use. The lack of comfort is more likely to cause occupational injuries affecting hearing in places such as beauty salons.
為改進前述情形，如第十二圖所示及台灣公告第566114號所示結構係具外殼4’、5’，並該外殼4’內具電熱機構42’並可由手部握持，並具出風口41’，內部具電熱機構42’，又另一外殼5’具入風口51’，內部具風扇52’，又於二外殼4’、5’間連設可導引氣流之導管6’，使得風扇52’動作可將外界氣流導入外殼5’內，再經由導管6’導入外殼4’內並經電熱機構42’加熱再由出風口41’導出，並前述設計可由外殼6’區隔入風之噪音，使得當具出風口41’之外殼4’靠近人體時不會感受較大噪音造成不適。In order to improve the foregoing situation, as shown in the twelfth figure and the structural brackets 4', 5' shown in Taiwan Bulletin No. 566114, the housing 4' has an electric heating mechanism 42' and can be held by the hand, and has The air outlet 41' has an electric heating mechanism 42' inside, and the other outer casing 5' has an air inlet 51', and has a fan 52' inside, and a conduit 6' for guiding the airflow is connected between the two outer casings 4', 5'. The fan 52' is actuated to introduce an external airflow into the outer casing 5', and then introduced into the outer casing 4' via the conduit 6' and heated by the electric heating mechanism 42' to be led out by the air outlet 41', and the foregoing design can be separated by the outer casing 6'. The noise of entering the wind makes it not feel louder when the outer casing 4' with the air outlet 41' is close to the human body.
然而前述設計因具導管6’，造成使用者手持外殼4’操作時將受該導管6’影響不便，且該導管6’更造成導風行程增加及減低出風效率缺失，又該吹風機之組件明顯增加，將增加吹風機成本。However, the foregoing design has a conduit 6', which causes the user to be inconvenient to be affected by the conduit 6' when the hand-held housing 4' is operated, and the conduit 6' further causes an increase in the air-guiding stroke and reduces the lack of airflow efficiency, and the components of the blower. Significant increase will increase the cost of the hair dryer.
又如第十三圖所示係另一習知改進結構，其組成結構與第十圖所示結構類同，並其差異在入風口13’位置可透氣之海棉7’，使得外界氣流由入風口13’導入時可經由該海棉7’吸音以具減小噪音功效。Another example is a modified structure as shown in the thirteenth figure, the composition of which is similar to the structure shown in the tenth figure, and the difference is that the air-permeable sponge 7' is located at the position of the air inlet 13', so that the external airflow is When the air inlet 13' is introduced, it can be sound-absorbing through the sponge 7' to reduce noise.
然而前述設計因該海棉7’同時將造成入風阻力，因而造成該吹風機出風量明顯大幅衰減，造成該吹風機效率不佳不符合使用需求功效缺失。However, the aforementioned design causes the air inlet resistance to be caused by the sponge 7' at the same time, thereby causing the air blower to be significantly attenuated significantly, resulting in the poor efficiency of the blower and the lack of efficacy in use.
本發明之目的在提供一種可有效減小吹風機動作進氣產生之噪音，並同時可令吹風機具較佳出風效率。The object of the present invention is to provide a noise that can effectively reduce the air intake generated by the blower, and at the same time, can make the hair dryer have better air efficiency.
