Description

手乾燥裝置hand dryer

本發明係有關一種使洗淨後被水弄濕的手變得乾燥的手乾燥裝置。 The present invention relates to a hand drying device for drying hands wetted with water after washing.

為保持手(手指)的衛生狀態，除了洗淨手的步驟以外，洗淨後的乾燥步驟也同樣重要。為此，至今為止已提出多種手乾燥裝置，不是以毛巾或手帕等擦拭洗淨後被水弄濕的手，而是藉由高速的空氣流吹至手上，吹掉附著手上之水滴，使手變得乾燥。 In order to keep hands (fingers) hygienic, in addition to the step of washing hands, the step of drying after washing is also important. For this reason, a variety of hand drying devices have been proposed so far. Instead of wiping the hands wet with water after wiping with towels or handkerchiefs, etc., they are blown to the hands by high-speed air flow to blow off the water droplets attached to the hands. Dry hands.

例如專利文獻1、2中雖然有提出朝向裝置本體內的乾燥室噴出空氣，並將在裝置本體上開口的手***口中***的手附著的水滴藉由空氣流吹掉，使手變得乾燥的手乾燥裝置。這種手乾燥裝置採用開放迴路(open loop)的方式，將吹至手上的空氣(排氣)排出至裝置本體外。具體而言，專利文獻1中所提出的手乾燥裝置，在裝置本體的左右的側壁上開設通氣口，將用於乾燥手的空氣(排氣)，從通氣口排出至裝置本體外。此外，專利文獻2中所提出的手乾燥裝置，在乾燥室的兩側有開口，將用於乾燥手的空氣(排氣)，從乾燥室兩側的開口直接排出至裝置本體外。 For example, although it is proposed in Patent Documents 1 and 2 that the air is sprayed toward the drying chamber in the device body, and the water droplets attached to the hand inserted in the hand insertion port opened on the device body are blown off by the air flow, so that the hand becomes dry. Hand dryer. This kind of hand drying device adopts an open loop method, and the air (exhaust gas) blown on the hand is discharged to the outside of the device body. Specifically, in the hand drying device proposed in Patent Document 1, vents are opened on the left and right side walls of the device body, and the air (exhaust air) used for drying hands is exhausted from the vents to the outside of the device body. In addition, the hand drying device proposed in Patent Document 2 has openings on both sides of the drying chamber, and the air (exhaust air) used for drying hands is directly exhausted from the openings on both sides of the drying chamber to the outside of the device body.

然而，若如專利文獻1、2所提出的手乾燥裝置採用開放迴路的方式作為空氣流動方式，被吹飛的水滴中含有各種細菌等往周圍飛散，手乾燥裝置的使用者或是周圍的人可能會將各種細菌等吸入。 However, if the hand drying device proposed in Patent Documents 1 and 2 adopts an open circuit as the air flow mode, the blown water droplets contain various bacteria, etc., and the user of the hand drying device or people around Various bacteria, etc. may be inhaled.

因此，專利文獻3提出一種手乾燥裝置，其採用閉合迴路(closed loop)的方式使空氣不需排出裝置本體外，使其在裝置本體內循環。雖然此手乾燥裝置也是通過出風部往乾燥室吹出的空氣吹至***乾燥室的手，並使該手乾燥。在此手乾燥裝置中，用於乾燥手的空氣(排氣)在裝置本體內循環，並回到出風口，重複此空氣再次用於乾燥手的動作。因此，在此手乾燥裝置中，因為用於乾燥手的空氣(排氣)不會排出，不會發生被空氣吹飛的水滴所含之各種細菌等與連同空氣排出裝置本體外的狀況。 Therefore, Patent Document 3 proposes a hand drying device, which adopts a closed loop (closed loop) method so that the air does not need to be discharged outside the device body, so that it circulates inside the device body. Although this hand drying device also blows the air blown to the hand inserted into the drying chamber by the air outlet part toward the drying chamber, and makes the hand dry. In this hand drying device, the air (exhaust air) used to dry hands circulates in the device body and returns to the air outlet, and this air is used to dry hands again. Therefore, in this hand drying device, because the air (exhaust gas) used for drying the hands is not discharged, various bacteria and the like contained in the water droplets blown by the air will not be discharged out of the device body together with the air.

另外，若更詳細的說明專利文獻3所提出的手乾燥裝置，此手乾燥裝置中，在乾燥室中用於乾燥手的空氣(排氣)由排氣管(空氣管道)往下方流動，此空氣透過被配置於裝置本體下部的接水槽被吸入送風馬達。接著，被吸入送風馬達的空氣，被排入形成於該送風馬達上方的空氣壓縮室，並被壓縮。被壓縮的空氣，透過從空氣壓縮室向上方之乾燥室延伸的兩個回流通道(前管與後管)往乾燥室進行回流，並在乾燥室的前後(正面側與背面側)分別形成開口之出風口被吹出。將此動作連續重複進行，能讓空氣不需排出裝置本體外，並在裝置本體內循環，但是這種手乾燥裝置會有以下的問題。 In addition, if the hand drying device proposed in Patent Document 3 is described in more detail, in this hand drying device, the air (exhaust air) used for drying hands in the drying chamber flows downward through the exhaust pipe (air duct), and the The air is sucked into the blower motor through the water receiving tank arranged at the lower part of the device body. Next, the air sucked into the blower motor is discharged into an air compression chamber formed above the blower motor, and compressed. The compressed air returns to the drying chamber through two return passages (front pipe and rear pipe) extending from the air compression chamber to the upper drying chamber, and openings are formed at the front and rear (front side and back side) of the drying chamber The air outlet is blown out. Repeating this action continuously can allow the air to circulate in the device body without being discharged outside the device body, but this hand drying device has the following problems.

亦即，從空氣壓縮室向上方之乾燥室延伸的兩個回流通道(前管與後管)是由細管構成，並且在中間有彎曲。如此一來，因為無法充分降低由此回流通道往乾燥室流動的空氣其流動阻力，也無法確保各空氣送出口往乾燥室內吹出的空氣之有足夠的流量及流速等，可能無法使***乾燥室內的手有效率地乾燥。因此，作為上述問題的對策，設置大型送風馬達等，會出現裝置的成本增加或製程複雜化的問題。又，空氣的流動若不夠流暢，空氣通過的聲音會變大，可能會產生噪音。因此作為上述問題的對策，在回流通道的管道周圍設置隔音材料等之對策成為必要，針對這一點也會出現裝置的成本增加或製程複雜化的問題。 That is, the two return passages (front pipe and rear pipe) extending from the air compression chamber to the upper drying chamber are made of thin pipes with bends in the middle. In this way, because the flow resistance of the air flowing from the return channel to the drying chamber cannot be sufficiently reduced, and the air blown from each air outlet to the drying chamber has sufficient flow rate and flow rate, it may not be possible to insert it into the drying chamber. hands dry efficiently. Therefore, installing a large blower motor or the like as a countermeasure against the above-mentioned problems would raise the cost of the device or complicate the manufacturing process. Also, if the flow of air is not smooth enough, the sound of air passing through will become louder, which may generate noise. Therefore, as a countermeasure against the above-mentioned problems, it is necessary to provide measures such as soundproofing materials around the pipes of the return passage, and there are also problems in that the cost of the device increases and the manufacturing process is complicated.

本發明鑒於上述問題而完成，其目的在於提供可防止附著在手上之水滴所含各種細菌等飛散至周圍，同時可以有效率乾燥洗淨後的手，且可實現運轉時之靜音化的手乾燥裝置。 The present invention was made in view of the above problems, and its object is to provide a hand that can prevent various bacteria contained in water droplets adhering to the hand from flying around, can effectively dry the washed hand, and can realize silent operation. Drying device.

為達成上述目的，本發明之手乾燥裝置(1、1-2)具有，在裝置本體(1A)上部形成開口，用於使洗淨後的手***該裝置本體(1A)內之***口(3)；以及被配置於上述***口(3)下方，用於乾燥從上述***口(3)***的手之乾燥室(4)；以及被配置於上述裝置本體(1A)下端之接水槽(5)；以及從上述乾燥室(4)往下方延伸並與上述接水槽(5)連通之排氣通道(6)；通過上述接水槽(5)與上述排氣通道(6)連接之送風馬達(7)；以及將上述送風馬達(7)送出的空氣壓縮之空氣壓縮室(8)；以及使在上述空氣壓縮室(8)壓縮之空氣回流至在上述乾燥室(4)形成開口的出風口(9、10、21、22)之回流通道(11)。其中從上述出風口(9、10、21、22)吹向上述乾燥室(4)的空氣，依上述排氣通道(6)、上述接水槽(5)、上述送風馬達(7)、上述空氣壓縮室(8)、上述回流通道(11)、上述出風口(9、10、21、22)的順序循環，在上述手乾燥裝置的上述裝置本體(1A)內形成空氣循環流；並且上述回流通道(11)在上述乾燥室(4)周圍形成。 In order to achieve the above object, the hand drying device (1, 1-2) of the present invention has an opening formed on the top of the device body (1A) for inserting the washed hands into the insertion port (1A) in the device body (1A). 3); and be arranged below the above-mentioned insertion port (3) for drying the drying chamber (4) of the hands inserted from the above-mentioned insertion port (3); and the water receiving tank ( 5); and the exhaust channel (6) extending downward from the above-mentioned drying chamber (4) and communicating with the above-mentioned water receiving tank (5); the air supply motor connected to the above-mentioned exhaust channel (6) through the above-mentioned water receiving tank (5) (7); and the air compression chamber (8) that compresses the air sent by the above-mentioned blower motor (7); The return channel (11) of the tuyere (9, 10, 21, 22). Wherein the air blown from the above-mentioned air outlets (9, 10, 21, 22) to the above-mentioned drying chamber (4), according to the above-mentioned exhaust passage (6), the above-mentioned water receiving tank (5), the above-mentioned air supply motor (7), the above-mentioned air Compression chamber (8), above-mentioned return flow The sequential circulation of the channel (11), the above-mentioned air outlets (9, 10, 21, 22) forms an air circulation flow in the above-mentioned device body (1A) of the above-mentioned hand drying device; and the above-mentioned return channel (11) is in the above-mentioned drying chamber (4) formed around.

據本發明，在乾燥室的周圍形成流路面積較大的回流通道，且此回流通道幾乎筆直地延伸到出風口，在中間並沒有明顯彎曲，所以流經此回流通道的空氣，其流動阻力可被抑制得很小。因此，若從出風口往乾燥室吹出的空氣量增加，使流速變高，可以有效率地由空氣流吹走附著在***乾燥室的手上之水滴，能夠有效率地使手變得乾燥。又，幾乎筆直地回流通道可使空氣不被阻礙，並可流暢地流動，回流通道中不會發生空氣的亂流、渦等，可以抑制伴隨著空氣流動發出的噪音，所以此手乾燥裝置也可以實現運轉時之靜音化。 According to the present invention, a return channel with a larger flow path area is formed around the drying chamber, and the return channel extends almost straight to the air outlet without obvious bending in the middle, so the flow resistance of the air flowing through the return channel Can be suppressed very little. Therefore, if the air volume blown from the air outlet to the drying chamber is increased and the flow velocity is increased, the water droplets attached to the hands inserted into the drying chamber can be efficiently blown away by the air flow, and the hands can be dried efficiently. In addition, the almost straight return channel can make the air not be hindered, and can flow smoothly. There will be no turbulent flow, vortex, etc. of air in the return channel, which can suppress the noise accompanying the air flow, so this hand dryer is also It can realize the quietness during operation.

而在此手乾燥裝置中，採用閉合迴路方式作為流動方式，使空氣在裝置本體內循環。因此，用於乾燥手的空氣(排氣)不會被排放到裝置本體外，不會發生附著在手上的水滴所含的各種細菌等與空氣一起排放到裝置本體外將周圍環境污染這種問題。 In this hand drying device, however, a closed circuit method is adopted as the flow method, and air is circulated in the device body. Therefore, the air (exhaust air) used to dry hands will not be discharged outside the device body, and various bacteria and the like contained in water droplets attached to the hands will not be discharged out of the device body together with the air to pollute the surrounding environment. question.

在此上述乾燥室(4)的周圍由內外雙層壁(4a、4b)構成，可以由此內外雙層壁(4a、4b)之間所形成之空間構成上述回流通道。 The above-mentioned drying chamber (4) is surrounded by inner and outer double walls (4a, 4b), and the space formed between the inner and outer double walls (4a, 4b) can form the above-mentioned return channel.

據上述的結構，由於回流通道形成於乾燥室的周圍，其在俯視圖中具有矩形環狀的流路剖面，該回流通道的流路面積變大，在此回流且被引導向出風口的空氣其流量及流速都進一步增加，通過高速的空氣流，可以使手更有效率地變得乾燥。 According to the above-mentioned structure, since the return channel is formed around the drying chamber, it has a rectangular ring-shaped flow channel section in a plan view, and the flow channel area of the return channel becomes larger, and the air that returns here and is guided to the air outlet The flow rate and flow rate are further increased, and the hands can be dried more efficiently through the high-speed air flow.

又，上述乾燥室(4)的前後或左右設有一對上述出風口(9、10、21、22)，上述回流通道(11)可由前後或左右設置的一對分隔壁(16、23)分隔。 Also, a pair of the above-mentioned air outlets (9, 10, 21, 22) are arranged at the front, rear or left and right of the above-mentioned drying chamber (4), and the above-mentioned return passage (11) can be separated by a pair of partition walls (16, 23) arranged at the front, rear or left and right. .

據上述的結構，流經回流通道的空氣由分隔壁被分成兩部分，因為被分成兩部分的空氣被分別均等的分配且被分別引導至一對的出風口，兩個出風口吹出的空氣的量及流速皆均等，防止流量及流速的偏差，可以使手背手心幾乎同時有效率地變得乾燥。 According to the above-mentioned structure, the air flowing through the return channel is divided into two parts by the partition wall, because the air divided into two parts is distributed equally and respectively guided to a pair of air outlets, the air blown out of the two air outlets The amount and flow rate are equal, preventing the deviation of flow rate and flow rate, and can effectively dry the back and palm of the hand almost at the same time.

另外，上述排氣通道(6)，以從上述乾燥室(4)向下方直線延伸至上述接水槽(5)為佳。 In addition, the above-mentioned exhaust channel (6) preferably extends straight downward from the above-mentioned drying chamber (4) to the above-mentioned water receiving tank (5).

據上述的結構，因為在乾燥室中用於乾燥手的空氣(排氣)能夠在幾乎筆直的排氣通道流暢地流向接水槽，該空氣的流動阻力可被抑制得很小，因此該空氣的流量及流速可以增加。進而使裝置本體內循環的空氣流速及流量增加，手可以更有效率地變得乾燥的同時，空氣流動伴隨的噪音也可以被抑制得很小，可以實現該手乾燥裝置運轉時之靜音化。 According to the above-mentioned structure, because the air (exhaust air) used for drying hands in the drying chamber can flow smoothly toward the sink in the almost straight exhaust passage, the flow resistance of the air can be suppressed very little, so the air flow The flow rate and velocity can be increased. Furthermore, the velocity and flow rate of the air circulated in the device body are increased, and while the hands can be dried more efficiently, the noise accompanying the air flow can also be suppressed very little, and the quiet operation of the hand drying device can be realized.

而構成上述回流通道(11)的內外雙層壁(4a、4b)之中，也可以在正面側的外壁(4b)的一部分形成向背面側凹陷的凹部(4b1)。 On the other hand, among the inner and outer double walls (4a, 4b) constituting the return channel (11), a recess (4b1) recessed toward the back side may be formed on a part of the outer wall (4b) on the front side.

據上述的結構，構成回流通道的內外雙層壁之中的正面側的外壁的一部分形成之凹部，例如可以有效地利用作為控制板的儲存空間，可以實現該手乾燥裝置的小型化。 According to the above-mentioned structure, the concave portion formed by a part of the outer wall on the front side among the inner and outer double walls constituting the return flow channel can effectively use the storage space as a control panel, for example, and realize the miniaturization of the hand dryer.

又，上述出風口(9、10、21、22)可由多個狹縫或圓孔構成，狹縫或圓孔分別朝向***上述乾燥室(4)的手(H)之多個指縫部分(Y)形成開口。 Also, the above-mentioned air outlets (9, 10, 21, 22) can be made of a plurality of slits or circular holes, and the slits or circular holes are respectively directed towards the multiple finger crevices of the hands (H) inserted into the above-mentioned drying chamber (4) ( Y) Form the opening.

據上述的結構，乾燥室內從出風口吹出的空氣能夠直接吹到容易殘留水滴的指縫部分，進而使水滴能有效地被吹飛並被去除，能使整隻手都同時且快速地變得乾燥。 According to the above-mentioned structure, the air blown from the air outlet in the drying room can be directly blown to the fingertips where water droplets are likely to remain, so that the water droplets can be effectively blown away and removed, and the whole hand can be simultaneously and quickly dry.

此外，在空氣的流向上，第一過濾部件(12)可以被配置於上述接水槽(5)及上述送風馬達(7)之間。 In addition, the first filter member (12) may be disposed between the water receiving tank (5) and the air blowing motor (7) in the flow direction of the air.

又，在空氣的流向上，第二過濾部件(13)可以被配置於上述送風馬達(7)及上述空氣壓縮室(8)之間。 In addition, a second filter member (13) may be disposed between the air blowing motor (7) and the air compression chamber (8) in the air flow direction.

據上述的結構，在裝置本體內循環的空氣通過第一過濾部件及/或第二過濾部件而被淨化，因為在其中含有的塵埃等的微粒子、各種細菌等會被去除，這些微粒子、各種細菌等不會附著在手上，乾燥後的手可以保持在衛生的狀態。 According to the above-mentioned structure, the air circulating in the device body is purified by the first filter member and/or the second filter member, because the particles such as dust and various bacteria contained therein will be removed, and these particles, various bacteria, etc. It does not stick to the hands, and the hands can be kept in a hygienic state after drying.

而具有控制驅動上述送風馬達(7)之控制手段(19)，以及，檢測***上述乾燥室(4)的手之檢測手段(17)，其中，上述檢測手段(17)設置於上述***口(3)，並且上述檢測手段(17)檢測到手的前端時，上述控制手段(19)能開始驅動上述送風馬達(7)。 And there is a control means (19) for controlling and driving the above-mentioned air blowing motor (7), and a detection means (17) for detecting the hand inserted into the above-mentioned drying chamber (4), wherein, the above-mentioned detection means (17) is arranged at the above-mentioned insertion port ( 3), and when the detection means (17) detects the front end of the hand, the control means (19) can start to drive the air blowing motor (7).

據上述的結構，由檢測手段檢測到***乾燥室的手的前端時，在整隻手***乾燥室之前送風馬達就會被驅動並且從出風口吹出空氣，因此手的乾燥不會有時間上的延遲(time lag)，能夠快速完成。此外，由於直到乾燥結束後的手從乾燥室完全抽出並且該手的前端通過檢測手段，送風馬達才會停止，因此手可以充分的被乾燥。 According to the above-mentioned structure, when the front end of the hand inserted into the drying chamber is detected by the detection means, the air blowing motor will be driven and the air will be blown out from the air outlet before the whole hand is inserted into the drying chamber, so the drying of the hand will not take time. Delay (time lag), can be completed quickly. In addition, since the air blowing motor is not stopped until the hand after drying is completely drawn out from the drying chamber and the front end of the hand passes through the detection means, the hand can be sufficiently dried.

據本發明，能夠提供防止附著在手上之水滴所含各種細菌等飛散至周圍，同時可以有效率乾燥洗淨後的手，且可實現運轉時之靜音化的手乾燥裝置。 According to the present invention, it is possible to provide a hand drying device that prevents various bacteria contained in water droplets adhering to the hands from scattering to the surroundings, efficiently dries washed hands, and realizes quiet operation.

於此，從乾燥室4內部觀察前側(正面側)的出風口9的狀態如圖4(圖2的箭頭C方向的視圖)所示，各出風口的構成為在左右方向上細長矩形狹縫。這些狹縫被配置為對應到***乾燥室4的左右手H之指縫部分Y，左右各有4個並互相間隔。此外，圖4所示左右手H是為說明與出風口9的位置關係的示意圖，並未表示實際狀態。 Here, the state of the air outlet 9 on the front side (front side) viewed from the inside of the drying chamber 4 is shown in FIG. 4 (view in the direction of arrow C in FIG. 2 ). . These slits are arranged so as to correspond to the finger gaps Y of the left and right hands H inserted into the drying chamber 4, and there are four on the left and right sides and are spaced apart from each other. In addition, the left and right hands H shown in FIG. 4 are schematic diagrams illustrating the positional relationship with the air outlet 9, and do not represent the actual state.

順帶一提，雖然在本實施型態中各出風口9形成為橫向較長之矩形狹縫，也可以形成為如圖5(a)所示的圓孔9a或圖5(b)所示在橫向上連接成一細長狹縫9b。於此，各出風口9的形狀及個數，可以任意且不限定於本實施型態中所示之型態。 Incidentally, although in this embodiment, each air outlet 9 is formed as a horizontally long rectangular slit, it can also be formed as a circular hole 9a as shown in Figure 5(a) or as shown in Figure 5(b). It is connected to form an elongated slit 9b in the transverse direction. Here, the shape and number of the air outlets 9 can be arbitrary and are not limited to those shown in this embodiment.

此外，以上雖只針對其中一方(前側)的出風口9之形狀及配置進行說明，由於另一方(後側)的出風口10之形狀及配置與前述其中一方(前側)的出風口9相同，其說明及圖式不再贅述。 In addition, although the above only describes the shape and configuration of the air outlet 9 on one side (the front side), because the shape and configuration of the air outlet 10 on the other side (the rear side) are the same as the air outlet 9 on the one side (the front side), Its description and drawings will not be described in detail.

而本實施型態中，如圖3所示，形成於乾燥室4周圍的回流通道11，該回流通道11的左右部分(圖3的上下部分)的前後方向的中央設有上下方向(圖3的紙面垂直方向)較長的分隔壁16，並由此分隔壁16劃分出前側區域11F以及後側區域11B。然後，前側的多個出風口9在此回流通道11的前側區域11F形成開口，後側的多個出風口10在後側區域11B形成開口。 And in the present embodiment, as shown in Figure 3, be formed in the backflow channel 11 around drying chamber 4, the center of front and rear direction of the left and right part (upper and lower part of Figure 3) of this backflow channel 11 is provided with up and down direction (Figure 3). The partition wall 16 that is long in the vertical direction of the paper plane) divides the front side area 11F and the rear side area 11B by the partition wall 16 . Then, the multiple air outlets 9 on the front side form openings in the front area 11F of the return channel 11 , and the multiple air outlets 10 on the rear side form openings in the rear area 11B.

而本實施型態的手乾燥裝置1，如圖2所示，乾燥室4的上端的***口3，為了檢測乾燥室4內的手之***和移出，設有光學感測器(檢測手段)17。此光學感測器17包括在***口3的左右其中一方配置的發光部(未圖示)以及在另一方配置的受光部。通過發光部射出之光線被手遮住而受光部未檢測到光，以檢測手的***，被稱為光遮斷器(photo-interrupter)。於此，如圖2所示，此光學感測器17被配置於連接前後出風口9、10的中心的直線L(以虛線所示)的上方。因此，光學感測器17可以在手***乾燥室4之前就檢測到手。此外，光學感測器17可以設置在***口3的左右兩側，或是只設置在單側也可以。 And the hand drying device 1 of present embodiment, as shown in Figure 2, the insertion port 3 of the upper end of drying chamber 4, in order to detect the insertion and removal of the hand in drying chamber 4, be provided with optical sensor (detection means) 17. The optical sensor 17 includes a light emitting unit (not shown) disposed on one of the left and right sides of the insertion port 3 and a light receiving unit disposed on the other. The light emitted by the light-emitting part is blocked by the hand and the light-receiving part does not detect the light to detect the insertion of the hand, which is called a photo-interrupter (photo-interrupter). Here, as shown in FIG. 2 , the optical sensor 17 is disposed above the straight line L (shown by a dotted line) connecting the centers of the front and rear air outlets 9 , 10 . Therefore, the optical sensor 17 can detect the hand before the hand is inserted into the drying chamber 4 . In addition, the optical sensor 17 may be provided on the left and right sides of the insertion port 3, or may be provided on only one side.

又，如圖2所示，在乾燥室4正面側的上部，為了在該手乾燥裝置1運轉中亮起以照亮乾燥室4內部，設有LED燈18。此LED燈18的結構是多個LED光源在乾燥室4內部的左右方向(圖2垂直紙面的方向)沿著適當的間隔以直線排列，並被***口3的側壁覆蓋，***口3的側壁構成外殼2的殼體構件2A一部分。因此，從***口3的上方不會直視LED燈18，對手乾燥裝置1的使用者而言，LED燈18所發出的光線不會直接與眼睛接觸，乾燥室4整體的照明是看起來舒適的間接照明。此外，LED燈18發出的光線顏色除了藍色以外，白色或紅色等也可以，若使用藍色還能獲得殺菌效果。 Also, as shown in FIG. 2 , an LED lamp 18 is provided in the upper part of the front side of the drying chamber 4 in order to light up the inside of the drying chamber 4 during operation of the hand dryer 1 . The structure of this LED lamp 18 is that a plurality of LED light sources are in the left-right direction (Fig. They are arranged in a straight line and covered by the side wall of the insertion port 3 constituting a part of the case member 2A of the case 2 . Therefore, the LED lamp 18 will not be seen directly from above the insertion port 3, and the light emitted by the LED lamp 18 will not directly contact the eyes of the user of the hand drying device 1, so that the overall lighting of the drying chamber 4 looks comfortable. indirect lighting. In addition, the color of the light emitted by the LED lamp 18 can be white or red other than blue, and a bactericidal effect can also be obtained if blue is used.

進一步地如圖2所示，凹部4b1形成於構成乾燥室4一部分的外壁4b的一部分上，空間S形成於凹部4b1與外殼2之間，具有控制基板的控制手段19被配置於空間S。如此有效利用空間S配置控制手段19，可以實現手乾燥裝置1的小型緻密(compact)化。 Further, as shown in FIG. 2, a recess 4b1 is formed on a part of the outer wall 4b constituting a part of the drying chamber 4, a space S is formed between the recess 4b1 and the housing 2, and a control means 19 having a control board is disposed in the space S. By effectively utilizing the space S and arranging the control means 19 in this way, the compactness of the hand dryer 1 can be realized.

於此，基於圖6說明本實施型態的手乾燥裝置1的系統結構，如同圖6所示，控制手段19與電源(例如：商業用電源)20電連接，同時也與光學感測器17與送風馬達7及LED燈18電連接。此外，控制手段19在光學感感測器17檢測到乾燥室4內有手***並輸入訊號後，會驅動送風馬達7並點亮LED燈18，詳細內容在後文敘述。 Here, the system structure of the hand drying device 1 of this embodiment is described based on FIG. 6. As shown in FIG. It is electrically connected with the blower motor 7 and the LED lamp 18 . In addition, after the optical sensor 17 detects that a hand is inserted into the drying chamber 4 and inputs a signal, the control means 19 will drive the blower motor 7 and turn on the LED lamp 18 , which will be described in detail later.

而如上所述構成的手乾燥裝置1，使外殼2的上部(***口3及其周圍)位於使用者的腰部高度，將外殼2的背面安裝於洗手間等的牆壁，其操作將基於圖7及圖8在以下說明。 And the hand drying device 1 of above-mentioned structure, make the top of shell 2 (insert port 3 and surroundings) be positioned at the user's waist height, the back side of shell 2 is installed on the wall such as washroom, its operation will be based on Fig. 7 and Figure 8 is described below.

圖7為表示本發明實施型態1的手乾燥裝置的空氣的循環之側剖面圖。圖8為表示本發明實施型態1的手乾燥裝置的動作順序之流程圖。 Fig. 7 is a side sectional view showing the circulation of air in the hand dryer according to Embodiment 1 of the present invention. Fig. 8 is a flow chart showing the operation procedure of the hand drying device according to Embodiment 1 of the present invention.

首先，使用者的手是否從在手乾燥裝置1上端開口的***口3***乾燥室4內，即，光學感測器17判斷是否檢測到手(圖8的步驟S1)。在此情況下，因為光學感測器17被配置於***口3，如果在使用者的手***乾燥室4之前由光學傳感器17檢測到用戶的手的前端，光學感測器17會向控制手段19發送檢測訊號。 First, whether the user's hand is inserted into the drying chamber 4 from the insertion port 3 opened at the upper end of the hand drying device 1, that is, the optical sensor 17 judges whether the hand is detected (step S1 of FIG. 8 ). In this case, because the optical sensor 17 is disposed at the insertion port 3, if the front end of the user's hand is detected by the optical sensor 17 before the user's hand is inserted into the drying chamber 4, the optical sensor 17 will send a message to the control means. 19 Send a detection signal.

若由光學感測器17檢測到使用者的手***乾燥室4(步驟S1：YES)，控制手段19在開始驅動送風馬達7的同時點亮LED燈18(步驟S2)。若送風馬達7被驅動，從該送風馬達7被送出的空氣如圖7的箭頭所示通過高效率粒子空氣濾器13流入空氣壓縮室8，流入此空氣壓縮室8的空氣，被該空氣壓縮室壓縮，其壓力增加。然後被空氣壓縮室8壓縮之空氣，如圖7所示，流入回流通道11，此回流通道11流向上方的前後的出風口9、10。 If the optical sensor 17 detects that the user's hand is inserted into the drying chamber 4 (step S1: YES), the control means 19 starts to drive the blower motor 7 and at the same time turns on the LED lamp 18 (step S2). If the blower motor 7 is driven, the air sent out from the blower motor 7 will flow into the air compression chamber 8 through the high-efficiency particle air filter 13 as shown by the arrow in Figure 7, and the air flowing into the air compression chamber 8 will be compressed by the air compression chamber. compressed, its pressure increases. Then the air compressed by the air compression chamber 8, as shown in FIG.

於此，如圖2所示，因回流通道11由分隔壁16劃分出前側區域11F以及後側區域11B，從空氣壓縮室8流入回流通道11的空氣被均等分成兩部分並分配到前側區域11F以及後側區域11B中，流入前側區域11F以及後側區域11B後，分別從前側的出風口9及後側的出風口10朝向乾燥室4內的P點以相反方向吹出，用以乾燥***乾燥室4的使用者的手背手心。 Here, as shown in FIG. 2 , since the return channel 11 is divided into the front area 11F and the rear area 11B by the partition wall 16 , the air flowing into the return channel 11 from the air compression chamber 8 is equally divided into two parts and distributed to the front area 11F. And in the rear side region 11B, after flowing into the front side region 11F and the rear side region 11B, it is blown out from the air outlet 9 on the front side and the air outlet 10 on the rear side towards the P point in the drying chamber 4 in the opposite direction, for drying and inserting drying. The back of the palm of the user's hand in chamber 4.

而且，因為回流通道11如上述形成於乾燥室4的整個外周，其流路面積較以前更大。並且，此回流通道幾乎筆直地延伸到出風口9、10，在中間並沒有明顯彎曲，所以流經此回流通道的空氣，其流動阻力可被抑制得很小。因此，回流通道11中被分成兩部份流入前側區域11F以及後側區域11B的空氣，其流量及流速皆增加。從各出風口9、10往乾燥室4吹出的空氣量增加的同時流速也變快。結果***乾燥室4的使用者的手背手心上所附著的水滴被高速的空氣流吹飛，手背手心有效率且同時變乾燥。又，幾乎筆直的回流通道11可使空氣不被阻礙，並可流暢的流動，回流通道11中不會發生空氣的亂流、渦等，可以抑制伴隨著空氣流動發出的噪音，所以此手乾燥裝置也可以實現運轉時之靜音化。 Also, since the return passage 11 is formed on the entire periphery of the drying chamber 4 as described above, its flow path area is larger than before. Moreover, the return channel extends almost straight to the air outlets 9 and 10 without obvious bending in the middle, so the flow resistance of the air flowing through the return channel can be suppressed very little. Therefore, the flow rate and velocity of the air divided into two parts into the front area 11F and the rear area 11B in the return channel 11 are increased. The air volume blown from each air outlet 9, 10 to the drying chamber 4 increases and the flow velocity also becomes faster. As a result, the water droplets attached to the palms of the hands of the user inserted into the drying chamber 4 are blown away by the high-speed air flow, and the palms of the hands are efficiently and simultaneously dried. Moreover, the almost straight return channel 11 can make the air not be hindered, and can flow smoothly, and there will be no turbulent flow, vortex, etc. of the air in the return channel 11, which can suppress the noise accompanying the air flow, so the hands are dry. The device can also achieve quietness during operation.

特別是在本實施型態中，由於回流通道11中被分成兩部份的空氣分別均等分配到前側區域11F以及後側區域11B並分別流向出風口9、10，所以從兩出風口9、10吹出的空氣的量及流速均等，可以防止流量及流速的偏差，使手背手心可以幾乎同時且有效率地變乾燥。 Especially in this embodiment, since the air divided into two parts in the return channel 11 is equally distributed to the front area 11F and the rear area 11B respectively and flows to the air outlets 9 and 10 respectively, Therefore, the volume and flow velocity of the air blown from the two air outlets 9 and 10 are equal, which can prevent the deviation of the flow and flow velocity, and make the back of the hand and the palm of the hand dry almost simultaneously and efficiently.

又，本實施型態中，從各出風口9、10吹向乾燥室4的P點(參考圖7)，如上述，由於是假定手的指縫部分設定P點，將空氣集中吹到容易殘留水滴的手的指縫部分，同時且均勻地乾燥整個手。進一步地，在本實施型態中，如圖4所示，出風口9、10(圖4中僅示出了其中一個)被設置在對應於手的指縫部分的位置，如圖4的箭頭所示，各出風口9、10吹出的空氣集中吹到兩手H的各指縫部分Y。因此能夠更有效的乾燥容易殘留水滴的手H的指縫部分Y。 Again, in the present embodiment, blow to the P point (referring to Fig. 7) of drying chamber 4 from each air outlet 9,10, as above-mentioned, owing to be to assume the finger gap part of hand to set P point, air is concentrated and blown to easy The part between the fingers where water droplets remain, dries the entire hand simultaneously and evenly. Further, in this embodiment, as shown in FIG. 4 , the air outlets 9 and 10 (only one of which is shown in FIG. 4 ) are arranged at positions corresponding to the crevices of the fingers of the hand, as shown by the arrows in FIG. 4 As shown, the air blown out by each air outlet 9, 10 is concentrated and blown to each finger crevice part Y of both hands H. Therefore, it is possible to more effectively dry the interfinger portion Y of the hand H where water droplets tend to remain.

如圖7的箭頭所示，如上述用於乾燥使用者的手的空氣(排氣)在乾燥室4向下方流動，但由於乾燥室4其流路面積向下方變窄，在此乾燥室4流動的空氣流速會逐漸變快。然後，此空氣(排氣)從乾燥室4流入排氣通道6，且該排氣通道6向下流向接水槽5，但由於如上所述排氣通道6向下方呈筆直延伸，所以空氣(排氣)能夠在此排氣通道6順暢地流向接水槽5。因此，空氣(排氣)的流動阻力可以被抑制，且該空氣的流量及流速可以增加的同時，可以抑制伴隨著空氣流動發出的噪音，可以實現該手乾燥裝置1運轉時之靜音化。 As shown by the arrow in Figure 7, the air (exhaust) that is used to dry the hands of the user flows downward in the drying chamber 4 as described above, but because the flow path area of the drying chamber 4 is narrowed downwards, the drying chamber 4 The flowing air velocity will gradually become faster. Then, this air (exhaust) flows into the exhaust passage 6 from the drying chamber 4, and the exhaust passage 6 flows downward to the water receiving tank 5, but since the exhaust passage 6 extends straight downward as described above, the air (exhaust) Gas) can flow smoothly to the water receiving tank 5 in the exhaust passage 6 here. Therefore, the flow resistance of the air (exhaust air) can be suppressed, and the flow rate and velocity of the air can be increased, and the noise accompanying the air flow can be suppressed, so that the hand dryer 1 can be quiet during operation.

然後，從排氣通道6流入接水槽5的空氣(排氣)中所含的水滴由於與空氣的比重不同而與空氣分離，在接水槽5落下，並儲存在接水槽5中。此外，當接水槽5裝滿水時，可以將接水盤5朝前側拉出，並從裝置本體1A移除，可以將累積在接水盤5中的水倒出。 Then, the water droplets contained in the air (exhaust gas) flowing into the water receiving tank 5 from the exhaust passage 6 are separated from the air due to the difference in specific gravity, fall in the water receiving tank 5 , and are stored in the water receiving tank 5 . In addition, when the water receiving tank 5 is filled with water, the water receiving tray 5 can be pulled out toward the front side and removed from the apparatus body 1A, and the water accumulated in the water receiving tray 5 can be poured out.

在接水槽5去除水滴的空氣通過預濾器12淨化後，被吸入送風馬達7，由該送風馬達7升壓後送出，之後，重複上述相同的操作，並且持續由分別從空氣出口9、10吹出的空氣使***乾燥室4的手變得乾燥。 After being purified by the pre-filter 12, the air that removes water droplets in the water receiving tank 5 is sucked into the air supply motor 7, and then sent out after being boosted by the air supply motor 7. Afterwards, the same operation as above is repeated, and it is continuously blown out from the air outlets 9 and 10 respectively. The air makes the hand inserted into the drying chamber 4 dry.

因此，在本實施型態的手乾燥裝置1中，如圖7的箭頭所示，空氣依排氣通道6、接水槽5、送風馬達7、空氣壓縮室8、回流通道11、出風口9、10的順序循環，在裝置本體1A內形成空氣循環流。如此，在本實施型態的手乾燥裝置1中，採用閉合迴路方式作為流動方式，使空氣在裝置本體內循環。因此，用於乾燥手的空氣(排氣)不會被排放到裝置本體1A外，不會發生附著在手上的水滴所含的各種細菌等與空氣一起排放到裝置本體外將周圍環境污染這種問題。 Therefore, in the hand drying device 1 of the present embodiment, as shown by the arrows in Figure 7, the air flows through the exhaust passage 6, the water receiving tank 5, the air supply motor 7, the air compression chamber 8, the return passage 11, the air outlet 9, The sequence of 10 cycles forms an air circulation flow in the device body 1A. Thus, in the hand dryer 1 of this embodiment, the closed circuit system is adopted as a flow system, and air is circulated in the device main body. Therefore, the air (exhaust air) used to dry the hands will not be discharged outside the device body 1A, and various bacteria and the like contained in water droplets attached to the hands will not be discharged to the outside of the device body together with the air to pollute the surrounding environment. kind of problem.

又，在裝置本體1A內循環的空氣通過預濾器12及高效率粒子空氣濾器13而被淨化，因為在其中含有的塵埃等的微粒子、各種細菌等會被去除，這些微粒子、各種細菌等不會附著在手上，乾燥後的手可以保持在衛生的狀態。 Also, the air circulated in the device body 1A is purified by the pre-filter 12 and the high-efficiency particle air filter 13, because the particles such as dust and various bacteria contained therein will be removed, and these particles, various bacteria, etc. will not Attached to the hands, the hands can be kept in a hygienic state after drying.

此外，在本實施型態中，因為預濾器12與馬達殼7A之間設有網格狀的分隔板15，在預濾器12與馬達殼7A流動的空氣所引起的噪音可由分隔板15印制。又，雖未圖示，藉由在乾燥室4和排氣通道6的外周纏繞吸音材料，也可以抑制伴隨著空氣流動發出的噪音。 In addition, in this embodiment, since the grid-shaped partition 15 is provided between the pre-filter 12 and the motor casing 7A, the noise caused by the air flowing between the pre-filter 12 and the motor casing 7A can be eliminated by the partition 15. print. Also, although not shown, by wrapping sound-absorbing material around the outer peripheries of the drying chamber 4 and the exhaust duct 6, noise accompanying air flow can also be suppressed.

接著，在圖8所示步驟2中，送風馬達7被驅動並且點亮LED燈18時，乾燥室4內被LED燈18發出的光間接照亮，使用者可以看到乾燥室4內的狀況，特別是若LED燈18發出藍光時，乾燥室4內可以由紫外線的殺菌作用進行殺菌。於此，由於光學感測器17被設置於乾燥室4上端的***口3，***乾燥室4的手的前端被光學感測器17檢測到時，在整隻手***乾燥室4內之前，送風馬達7就會被驅動並且從出風口9、10吹出空氣，因此手的乾燥不會有時間上的延遲(time lag)。 Then, in step 2 shown in FIG. 8 , when the blower motor 7 is driven and the LED lamp 18 is turned on, the interior of the drying chamber 4 is indirectly illuminated by the light emitted by the LED lamp 18 , and the user can see the situation in the drying chamber 4 , especially if the LED lamp 18 emits blue light, the drying chamber 4 can be sterilized by the sterilizing effect of ultraviolet rays. Here, since the optical sensor 17 is arranged on the insertion port 3 at the upper end of the drying chamber 4, when the front end of the hand inserted into the drying chamber 4 is detected by the optical sensor 17, before the entire hand is inserted into the drying chamber 4, The blowing motor 7 will be driven and the air will be blown out from the air outlets 9, 10, so the drying of the hands will not have a time delay (time lag).

之後，由光學感測器17判斷是否檢測到使用者由於手的乾燥結束而把手從乾燥室4抽出(步驟S3)。使用者把手從乾燥室4抽出後，光學感測器17中，受光部接受到發光部射出的光線，因此，該光學感測器17檢測到手從乾燥室4抽出，並將此訊號發送至控制手段19。即，光學感測器17檢測到手從乾燥室4抽出後(步驟S3：YES)，控制手段19停止驅動送風馬達並將LED燈18關閉(步驟S4)，完成一連串的動作(步驟S5)。 Afterwards, it is judged by the optical sensor 17 whether it is detected that the user pulls out the hand from the drying chamber 4 due to the completion of hand drying (step S3). After the user pulls out the hand from the drying chamber 4, the optical sensation In the detector 17, the light receiving part receives the light emitted by the light emitting part, so the optical sensor 17 detects that the hand is pulled out from the drying chamber 4, and sends this signal to the control means 19. That is, after the optical sensor 17 detects that the hand is withdrawn from the drying chamber 4 (step S3: YES), the control means 19 stops driving the blower motor and turns off the LED light 18 (step S4), and completes a series of actions (step S5).

然後，裝置本體1A內的空氣循環停止，也停止從出風口9、10吹出空氣，並且LED燈18對乾燥室4的間接照明也停止。於此，由於光學感測器17被設置於乾燥室4上端的***口3，即使將手從乾燥室4中抽出，在手的前端通過光學感測器17之前的一小段時間，送風馬達7仍然被驅動繼續乾燥手並且仍持續點亮LED燈18。因此，在手完全從乾燥室4抽出之前，出風口9、10不會停止出風，且也LED燈18也不會停止照明，可使手確實被乾燥，並且可以提高使用者的便利性。 Then, the air circulation in the device main body 1A stops, and the blowing of air from the air outlets 9, 10 also stops, and the indirect illumination of the drying chamber 4 by the LED lamp 18 also stops. Here, since the optical sensor 17 is arranged at the insertion port 3 at the upper end of the drying chamber 4, even if the hand is pulled out from the drying chamber 4, the air blowing motor 7 will be activated for a short period of time before the front end of the hand passes the optical sensor 17. Still be driven to continue to dry hand and still continue to light LED lamp 18. Therefore, before the hands are completely drawn out from the drying chamber 4, the air outlets 9, 10 will not stop the wind, and the LED lights 18 will not stop lighting, so that the hands can be definitely dried and the user's convenience can be improved.
