Description
本發明係關於一種風扇,尤其是一種可將一空間內部氣體導出至空間外部的換氣扇。 The present invention relates to a fan, and more particularly to a ventilating fan that can direct a space internal gas to the outside of the space.
請參照第1圖,其係一種習知的換氣扇9,該習知換氣扇9具有一本體91及一面板92。該本體91具有一外殼911,一渦扇912可轉動地設於該外殼911中,並位於該外殼911的進氣口與排氣口之間。該外殼911在較鄰近其進氣口處設一組裝部913以結合至天花板C。該面板92亦與天花板C結合,並遮罩住該組裝部913;該面板92另設有數個導氣開口921。使用時,該面板92裸露在室內,大部分的本體91則位於天花板C上方,並將該外殼911的排氣口連通至建築物的排風管路。如此,該渦扇912轉動時,可吸引室內氣體通過該面板92的導氣開口921流入該外殼911,再從該外殼911的排氣口流入建築物的排風管路。類似於該習知換氣扇9的一實施例已揭露於中華民國公告第I393846號「通風裝置」專利案當中。 Please refer to FIG. 1 , which is a conventional ventilating fan 9 having a body 91 and a panel 92 . The body 91 has a casing 911. A turbofan 912 is rotatably disposed in the casing 911 and located between the air inlet and the exhaust port of the casing 911. The outer casing 911 is provided with an assembly portion 913 to be coupled to the ceiling C at a position closer to its intake port. The panel 92 is also combined with the ceiling C and covers the assembly portion 913; the panel 92 is additionally provided with a plurality of air guiding openings 921. In use, the panel 92 is exposed indoors, and most of the body 91 is located above the ceiling C and connects the exhaust port of the housing 911 to the exhaust duct of the building. As described above, when the turbofan 912 rotates, the indoor air can be sucked into the outer casing 911 through the air guiding opening 921 of the panel 92, and then flowed into the exhaust duct of the building from the exhaust port of the outer casing 911. An embodiment similar to the conventional ventilating fan 9 has been disclosed in the "Ventilation Device" patent case of the Republic of China Announcement No. I393846.
其中,由於該面板92與該外殼911的組裝部913之間具有空隙A,且該面板92及該外殼911與天花板C結合時易留下微小的間隙。故,組裝該習知換氣扇9時,通常會在該面板92及該外殼911與天花板C之間加裝一海綿墊93,使該面板92及該外殼911能與天花板C密接,避免該習知換氣扇9運作時因此處漏風而產生噪音。 There is a gap A between the panel 92 and the assembly portion 913 of the casing 911, and the panel 92 and the casing 911 are easily combined with the ceiling C to leave a slight gap. Therefore, when assembling the conventional ventilating fan 9, a sponge pad 93 is usually installed between the panel 92 and the outer casing 911 and the ceiling C, so that the panel 92 and the outer casing 911 can be closely adhered to the ceiling C, avoiding the conventional knowledge. When the ventilating fan 9 operates, noise is generated due to air leakage.
然而,加裝該海綿墊93雖可暫時性的解決運作噪音的問題,但該海綿墊93的結構鬆散,且局部裸露而與室內或室外環境接觸,受濕氣及灰塵等因素影響,在使用一段時間後會逐漸變質、老化、剝落以致失效,無法耐久使用而需定期檢修及更換消耗品。再且,該海綿墊93也是待組裝定位的構件之一,更增添了由下而上組裝過程的繁瑣性。 However, the addition of the sponge pad 93 can temporarily solve the problem of operational noise, but the structure of the sponge pad 93 is loose and partially exposed to contact with the indoor or outdoor environment, and is affected by factors such as moisture and dust. After a period of time, it will gradually deteriorate, age, peel off and become invalid. It cannot be used for a long time and needs to be regularly repaired and replaced. Moreover, the sponge pad 93 is also one of the components to be assembled and positioned, which adds to the cumbersomeness of the bottom-up assembly process.
有鑑於此,習知換氣扇確實仍有加以改善之必要。 In view of this, the conventional ventilation fan does have the need to improve.

該換氣扇還可另包含一遮蔽件3,該遮蔽件3可以與該環牆21的局部結合而容設於該入風口S中,令使用者較不易由室內看見換氣扇的內部構件,具有提升換氣扇外觀質感的效果。該遮蔽件3可例如是一裝飾蓋板;或者,該遮蔽件3也可以是一燈組,使本發明換氣扇的本體兼具有照明功能。 The ventilating fan can further include a shielding member 3, and the shielding member 3 can be combined with the part of the annular wall 21 to be accommodated in the air inlet S, so that the user can hardly see the internal components of the ventilating fan from the room, and has the ventilating fan. The effect of the appearance of texture. The shielding member 3 can be, for example, a decorative cover; or the shielding member 3 can also be a light group, so that the body of the ventilation fan of the present invention has a lighting function.
又,當該遮蔽件3選擇為燈組時,還可在該遮蔽件3的外周與該環牆21之間形成氣隙,使室內的氣體在流入該入風口S的過程中,能同時牽引在該燈組正面周遭的空氣一同流入該入風口S,避免該燈組周遭因該燈組運作而逐漸升高溫度的空氣大量滯留在該燈組的正面;另搭配該殼座11的導引牆114導引氣流通過該燈組的背側(該燈組的上方),以雙重冷卻法提升該燈組的散熱效率。 Moreover, when the shielding member 3 is selected as the lamp group, an air gap can be formed between the outer periphery of the shielding member 3 and the ring wall 21, so that the gas in the room can be simultaneously pulled in the process of flowing into the air inlet S. The air around the front of the lamp group flows into the air inlet S together, so that the air that gradually increases the temperature of the lamp group due to the operation of the lamp group is prevented from staying on the front side of the lamp group; and the guide seat 11 is guided. The wall 114 directs airflow through the back side of the light group (above the light group) to increase the heat dissipation efficiency of the light group by double cooling.
更進一步地,本實施例還可選擇使該遮蔽件3不外凸超過該環牆21的底面;即,可以使該遮蔽件3整個內縮在該入風口S中,或是令該遮蔽件3的底面與該環牆21的底面切齊,使得整體換氣扇的厚度不會因為設置該遮蔽件3而增厚,且安裝該換氣扇後,也不會破壞整體隔離物F朝向室內表面的平整感,故整體換氣扇可提供使用者相當簡潔、有質感的視覺感受。 Further, the embodiment may further select that the shielding member 3 does not protrude beyond the bottom surface of the annular wall 21; that is, the shielding member 3 may be entirely retracted in the air inlet S, or the shielding member may be The bottom surface of the ring 3 is aligned with the bottom surface of the ring wall 21 so that the thickness of the entire ventilating fan is not thickened by the provision of the shielding member 3, and the ventilating fan is installed without damaging the flatness of the overall spacer F toward the indoor surface. Therefore, the overall ventilation fan can provide a user with a relatively simple and textured visual experience.
其中,該殼座11設有朝該框座2延伸的至少一個第一阻流環壁115;該框座2則設有朝該殼座11延伸的至少一個第二阻流環壁22,該第二阻流環壁22圈圍在該環牆21的外周。組裝時,只要直接將該殼座11及該框座2組裝至隔離物F的預定位置,即可使該第一阻流環壁115圈圍在該第二阻流環壁22的外周或內周,由該第一阻流環壁115與該第二阻 流環壁22共同形成擋止氣流的結構,使氣流在此處必須180度轉折才能流動,故幾乎不會有氣流從此處通過。 The housing 11 is provided with at least one first choke wall 115 extending toward the frame 2; the frame 2 is provided with at least one second choke wall 22 extending toward the housing 11 , The second choke wall 22 encircles the outer circumference of the ring wall 21. When assembling, the housing block 11 and the frame 2 are directly assembled to a predetermined position of the spacer F, so that the first choke wall 115 is enclosed around the outer circumference or the inner wall of the second choke wall 22. Week, by the first choke ring wall 115 and the second resistor The flow ring walls 22 together form a structure that blocks the flow of air so that the air flow must be turned 180 degrees here to flow, so that there is almost no air flow therethrough.
因此,該扇輪12被驅動旋轉時,可驅使該殼座11中的氣體流向該殼座11的排氣口112,使該殼座11中形成負壓,從而使室內的氣體能通過該入風口S而流入該殼座11中,再經該扇輪12導引,通過該殼座11的排氣口112排出至室外,達到換氣效果。 Therefore, when the fan wheel 12 is driven to rotate, the gas in the casing 11 can be driven to the exhaust port 112 of the casing 11, so that a negative pressure is formed in the casing 11, so that the gas in the chamber can pass through the inlet. The tuyere S flows into the casing 11, and is guided by the fan wheel 12, and is discharged to the outside through the exhaust port 112 of the casing 11, thereby achieving a ventilation effect.
在換氣的過程中,即使該殼座11或該框座2組裝至隔離物F處具有微小的間隙,仍可藉由該第一阻流環壁115與該第二阻流環壁22所共同形成的擋止氣流結構,有效避免因漏風而產生噪音的情況,使本發明的換氣扇可安靜運作,且組裝過程中不必加裝海綿墊,除可提升組裝便利性之外,還可耐久使用,不需定期檢修及更換形成氣密效果的消耗品。 In the process of ventilation, even if the housing 11 or the frame 2 is assembled to the spacer F with a slight gap, the first choke ring wall 115 and the second choke wall 22 can be The airflow structure formed together can effectively avoid the noise generated by the air leakage, so that the ventilation fan of the present invention can be quietly operated, and the sponge pad is not required to be assembled during the assembly process, and the assembly convenience can be improved, and the utility model can be used for a long time. There is no need to regularly repair and replace consumables that form a gas-tight effect.
又,請參照第4圖,該殼座11的第一阻流環壁115具有一第一凸出高度H1,該框座2的第二阻流環壁22具有一第二凸出高度H2。為確保該第一阻流環壁115與該第二阻流環壁22能確實達到擋止氣流的效果,較佳使該第一阻流環壁115與該第二阻流環壁22的投影重疊範圍R大於該第一凸出高度H1的五分之一,或大於該第二凸出高度H2的五分之一,以加長氣流流動的路徑,使流經此處的氣流不僅要大幅度地轉折,還要有足夠的流動力才能通過該擋止氣流的結構,故可確保氣流難以由此流通。 Moreover, referring to FIG. 4, the first choke ring wall 115 of the housing 11 has a first protruding height H1, and the second choke wall 22 of the frame 2 has a second protruding height H2. To ensure that the first choke ring wall 115 and the second choke ring wall 22 can surely achieve the effect of blocking the air flow, the projection of the first choke ring wall 115 and the second choke ring wall 22 is preferably performed. The overlapping range R is greater than one fifth of the first protruding height H1 or greater than one fifth of the second protruding height H2 to lengthen the flow path of the airflow, so that the airflow flowing therethrough is not only large At the turn of the ground, there must be sufficient flow force to pass the structure of the airflow, so that it is difficult to circulate the airflow.
基於上述技術概念,請參照第2、4圖,本發明換氣扇的第一實施例選擇使該框座2的第二阻流環壁22包含一第二內阻流環壁22a及一第二外阻流環壁22b,該第二外阻流環壁22b圈圍在該第二內阻流環壁22a的外周,且該第二外阻流環壁22b與該第二內阻流環壁22a之間形成一環溝23;組裝後,該殼座11的第一阻流環壁115可對位穿伸入該環溝23中。據此,該擋止氣流的結構可以令氣流在此處須經過二次180度的轉 折才能流動,故可提升防止氣流通過的效果。 Based on the above technical concept, referring to the second and fourth embodiments, the first embodiment of the ventilating fan of the present invention selects the second choke ring wall 22 of the frame 2 to include a second inner choke wall 22a and a second outer portion. a choke ring wall 22b surrounding the outer circumference of the second inner choke ring wall 22a, and the second outer choke ring wall 22b and the second inner choke ring wall 22a A ring groove 23 is formed between them; after assembly, the first choke ring wall 115 of the housing 11 can penetrate into the ring groove 23 in an opposite direction. Accordingly, the structure of the blocking airflow allows the airflow to undergo a second 180 degree turn here. Folding can flow, so it can improve the effect of preventing airflow.
請參照第4a圖,本實施例的換氣扇還可另包含二氣密環4,該氣密環4可例如為橡膠或矽膠等具有彈性的材質。該二氣密環4分別結合在該第二內阻流環壁22a及該第二外阻流環壁22b,以於該二氣密環4之間形成一狹縫G。該二氣密環4可選擇以套接或黏合等方式分別組裝結合於該第二內阻流環壁22a及該第二外阻流環壁22b,或是在製造該框座2時直接射包結合該第二內阻流環壁22a及該第二外阻流環壁22b。組裝後,該殼座11的第一阻流環壁115可以穿入或貫穿該狹縫G,且較佳使該二氣密環4可緊密貼接該第一阻流環壁115,據以完全封住氣流通道,更進一步地提升氣密效果。 Referring to FIG. 4a, the ventilating fan of this embodiment may further comprise a second airtight ring 4, which may be, for example, a resilient material such as rubber or silicone. The two airtight rings 4 are respectively coupled to the second inner choke ring wall 22a and the second outer choke ring wall 22b to form a slit G between the two airtight rings 4. The two airtight rings 4 can be assembled and coupled to the second inner choke ring wall 22a and the second outer choke wall 22b, respectively, by socketing or bonding, or directly when the frame 2 is manufactured. The bag combines the second inner choke ring wall 22a and the second outer choke ring wall 22b. After assembly, the first choke ring wall 115 of the housing 11 can penetrate or penetrate the slit G, and the second airtight ring 4 can be closely attached to the first choke ring wall 115. The air passage is completely sealed to further enhance the airtight effect.
值得一提的是,由於本發明可以預先將氣密環4組裝結合於第二阻流環壁22,甚至是在製造框座2時直接將氣密環4結合於第二阻流環壁22,故於將換氣扇組裝至隔離物F時,並不需像習知換氣扇9還要額外安裝海綿墊93(請配合參閱第1圖),及確保該海綿墊93被夾在隔離物F與該框座2或該殼座11之間的預定位置,才能達到氣密效果。因此,本發明即便設有氣密環4,仍不會影響將換氣扇組裝至隔離物F時的組裝便利性及效率。再且,該氣密環4相較於海綿墊屬於高密度材料,且該氣密環4被設置在該換氣扇的內部,而該設置處又不易有氣流流通,故該氣密環4較不易變質、老化,使得該氣密環4幾乎不需要進行更換。 It is worth mentioning that, since the present invention can pre-assemble the airtight ring 4 to the second choke ring wall 22, even when the frame 2 is manufactured, the airtight ring 4 is directly coupled to the second choke ring wall 22 Therefore, when assembling the ventilating fan to the spacer F, it is not necessary to additionally install the sponge pad 93 like the conventional ventilating fan 9 (please refer to FIG. 1), and to ensure that the sponge pad 93 is sandwiched between the spacer F and the The airtight effect can be achieved by the predetermined position between the frame 2 or the housing 11. Therefore, even if the airtight ring 4 is provided, the present invention does not affect the assembly convenience and efficiency when assembling the ventilating fan to the spacer F. Moreover, the airtight ring 4 is a high-density material compared to the sponge pad, and the airtight ring 4 is disposed inside the ventilating fan, and the arrangement is not easy to have airflow, so the airtight ring 4 is relatively difficult. Deterioration and aging make the airtight ring 4 almost unnecessary to be replaced.
其中,在以氣密環4組裝結合至第二阻流環壁22的實施例中,該二氣密環4可概呈ㄇ型,並分別以開口處套接於該第二內阻流環壁22a及該第二外阻流環壁22b的自由端處。據以在該殼座11的第一阻流環壁115穿入該狹縫G時,利用該第一阻流環壁115推抵該二氣密環4更緊密包覆該第二內阻流環壁22a及該第二外阻流環壁22b,同時利用該第二內阻流環壁22a及該第二外阻流環壁22b的自由端支撐該二氣密環4不至 於過度移動而錯開,故可提升氣密環4與第二阻流環壁22的結合穩固性。 In the embodiment in which the airtight ring 4 is assembled and coupled to the second choke ring wall 22, the two airtight ring 4 can be substantially ㄇ-shaped, and respectively sleeved at the opening to the second inner choke ring. The wall 22a and the free end of the second outer choke ring wall 22b. When the first choke ring wall 115 of the housing 11 penetrates the slit G, the first choke ring wall 115 is pushed against the two airtight ring 4 to more closely cover the second inner choke. The ring wall 22a and the second outer choke ring wall 22b simultaneously support the second airtight ring 4 by the free ends of the second inner choke ring wall 22a and the second outer choke ring wall 22b The staggering is excessively moved, so that the bonding stability of the airtight ring 4 and the second choke ring wall 22 can be improved.
相似地,請參照第4b圖,在另一實施例中,可選擇由一氣密環4’結合在該第二內阻流環壁22a及該第二外阻流環壁22b,該氣密環4’具有一穿隙41,該殼座11的第一阻流環壁115穿入或貫穿該穿隙41,且較佳由該穿隙41的內表面貼接該殼座11的第一阻流環壁115。如此,相較於第4a圖將二氣密環4分別組裝結合於該第二內阻流環壁22a及該第二外阻流環壁22b的實施例,本實施例的氣密環4’可一次結合該第二內阻流環壁22a及該第二外阻流環壁22b,具有更佳的組裝便利性並兼可提升組裝效率。 Similarly, referring to FIG. 4b, in another embodiment, a second inner choke ring wall 22a and the second outer choke ring wall 22b may be selected by a gas-tight ring 4', the airtight ring. 4' has a gap 41 through which the first choke ring wall 115 of the housing 11 penetrates or penetrates, and preferably the first surface of the housing 11 is attached to the inner surface of the housing 41 Flow ring wall 115. Thus, compared with the embodiment in which the second airtight ring 4 is assembled to the second inner choke ring wall 22a and the second outer choke ring wall 22b, respectively, the airtight ring 4' of the present embodiment is compared with the fourth embodiment. The second inner choke ring wall 22a and the second outer choke ring wall 22b can be combined at one time, which has better assembly convenience and can improve assembly efficiency.
