部13及清洗槽1。 首先’在乾燥運轉之開始初期，優先進行冷卻内部空 氣。因此，將送風機6之送風量設定少量，開啟阻尼器29a。 藉此，外部空氣通路14側之風量較通路15側之風量多。結 5果，風里多之外部空氣流53與風量少且高溫高濕之内部空 氣流54在匯合部13a匯合而混合，而促進内部空氣之冷卻。 進一步’在擴大部33 ’内部空氣與外部空氣匯合後之混合 流之流速減速’促進因内部空氣之冷卻而凝結之水分之排 除。進而，在攪拌部34,内部空氣與外部空氣均等地混合， 10進仃内部空氣之冷卻及水分刪減後，將排氣從排氣口 7排出 至餐具清洗乾燥機5〇之外部。 接著’以乾燥運轉之進行，減低清洗槽丨内之溫度時， 執仃清洗槽1内之乾燥優先之運轉。因此，送風機6之風量 支曰加。阻尼器29a、29b呈全開狀態。當阻尼器29a、29b呈 開狀悲日^ ’外部空氣通路14與通路15之風量之分配依通 路阻力控制，通路15侧之風量分配多於外部空氣通路14側 之風量。藉此，進行以乾燥為主目的之送風。 如此’藉送風機6之送風量之阻尼器29之開度變化，外 邻空氣通路14與通路15之分配依流體壓進行。如上述，進 行了冷卻及水分刪減之排氣從排氣口7流出。結果，可獲得 實現了結構之簡單化及低成本化之餐具清洗乾燥機50。 特別是進行使用高溫清洗水52之洗刷運轉時，為不直 接從排氣口 7排出清洗槽1内之高溫高濕之空氣，於乾燥運 轉之開始初期，以減低排氣溫度為主體，執行乾燥運轉。 13 200847987 因此，控制部17控制送風機6，以使外部空氣通路14側之風 量較通路15侧之風量多。 如此’本發明之餐具清洗乾燥機50在匯合部I3a中，對 高溫高濕之内部空氣混合外部空氣，進行内部空氣之冷卻 5及内部空氣所含之水分之凝結。因此，當要求内部空氣與 外部空氣均一且快速地混合時，混合部13之結構與匯合部 13a之結構極有效地發揮作用。 第3圖係顯示將通路之截面積假設為預定之一定值，將 2個通路並列配置時之通路截面之寬高比與通路間距離之 10 關係的特性圖。此外，在第3圖中，通路截面積一例為1〇〇〇 mm2。又，2個通路之壁之厚度假設為零。 如第3圖所示，當矩形截面之寬高比越大，2個通路、 亦即2個流體可配置越近。舉例言之，當寬高比為4時，相 較於寬高比1，通路間距離可實質上減半。因此，藉寬高比 15 為4以上，2個流路流體之配置構成接近，使通路壁消失而 匯合時，適合作為混合2個流體之條件。 如以上，本實施形態之餐具清洗乾燥機50之導入内部 空氣之通路15與導入外部空氣之外部空氣通路Η呈具寬高 比實質上大之矩形截面，接合相互之通路截面之長邊側而 2〇 匯合，構成匯合部13a。藉此，可獲得厚度薄之諸流之混合， 進行混合促進與遍及流全區之均等之混合。又，乾燥運轉 時，對高溫高濕之清洗槽1内之内部空氣在小梨之空氣内確 實混合足夠量之外部空氣。藉此，内部空氣迅速地冷卻。 結果，進行確實減低溫度濕度之排氣，而獲得實現了熱風 14 200847987 感之確實防止及機器小型化之鑫θ 士 ^ 士 之養具清洗乾燥機50。 對於直線方向延伸之通路 ^ ^ 15 ’外部空氣通路14呈有從 通路I5之側邊匯合之匯合部〗 4猎此，特別是外部空翕之 風量大於内部空氣之風量之 k 之 ^ 0 知運轉之開始初期，以減低 排氧/皿度為主體，進行乾燥運 ..,._ ^ 轉，外部空氣在匯合部13a彎 ，產生亂 >瓜。藉此，產生外 1二乳對内部空氣之攪拌作 用。因此，外部空氣可充分遍 減低内部空氣與外部空氣之混人=項各處。結果，可 10 15 20 此合不均，使混合通路32内之 内部空氣與外妓氣找合以料分布料Γ 截面==路截面之寬高比與外部空氣通路14之通路 4以上。藉此，流經通路15之内部空氣 辦管？、古触 風通路14之外部空氣流體流之 厗度雙溥。在流體流薄之狀能 ^ 〇 ^w ，内"卩空氣與外部空氣混 …果，促進内部空氣與外部空 在流速慢之流動區域，亦可右待玄丄 而易此口 空氣。 有政率地混合内部空氣與外部 外部空氣通路Η之通路截面 之通路截面之長邊長度爾與通路15 關係。藉此，如第2圖及第4Α圖所示，配置成外二^之 丨:之=截面之長邊與通路15之通路截面之長邊;= 柯 置外邛工軋通路14與通路15之空間，而 敢小化。結果，混合邻、生 、、青納·:: 型。此外，第4Α圖係從 /月洗槽1編相合部13時之部份侧面圖。 如第侧所示，外部空氣通㈣之通路戴面之長邊之 15 200847987 長度Wa亦可大於稱15之通_面之長叙長度魏。即， 亦可具有Wa>Wb之關係。X，通路15之通路截面之長邊亦 可配置於外部空氣通路14之通路截面之長邊内側。藉通路 15之通路戴面之長邊配置於外部空氣通路14之|路截面之 5長邊内側，在高溫高濕之内部空氣之長邊方向（寬度方向） 全區’可確實地供給外部空氣，撥拌内輕氣與外部空氣。 結果，在内部空氣與外部空氣之混合流中，可防止内部空 氣之-部份產生未混合部，使排氣溫度穩定化。此外，^ 4B圖係從清洗槽H則觀看混合部13時之部份侧面圖。 1〇 通路15具有從出口 11流動至下方至下降流部30及在下 降流動部之下游側使流體反轉朝上之上升流部31。使外部 通路14與上升流部31相對而匯合，形成匯合部…。藉此， 内部空氣之風量少時，以内部空氣加熱之外部空氣上升， 產生朝向排氣口 7側之流，形成減低流之變動之上升流。結 B果、，混合内部空氣與外部空氣後之上升流亦穩定化。藉產 生減低抓之^；動之上升流，可減低因内部空氣之流動變動 造成之内部空氣與外部空氣之混合流之溫度不均的產生。 又，於上升流部31之上游側設置下降流部3〇。藉此，清洗 運轉時或洗刷運轉時，可防止清洗水Μ進入外部空氣通路 20 14。又’可減低因自然對流產生之内部空氣外漏至排氣口 7。 於匯口 u|U3a之下游側具有通路截面積大之擴大部 33。藉此，在擴大部33，内部空氣與外部线匯合後之混 合流之流速緩慢，在擴大部33，產生璇渦狀之流等。結果， 混合流之流動變動，進行混合之促進。與此同時，促進因 16 200847987 内部空氣之冷卻凝結之水分之排除。 於匯合部13a之下游㈣有攪㈣部空氣與外部空氣 之混合流，以促進内部空氣與外部空氣之混合之攪拌部 34。藉此’可強力麟内部空氣與外部空氣之混合流。因 5此’促進内部空氣與外部空氣之混合，可均等混合内部空 氣與外部空氣。進而，可促進因冷卻内部空氣而產生之水 分之霧化。 於混合通路32之寬度方向延伸之吨舰突出，形成 授拌部34。藉此，可實現内部空氣與外部空氣之混合流之 H)確實攪拌。X，攪拌部34與混合通路32之壁一體化而形成。 藉此’可㈣齡卵之結_單化，低成本化之餐具清 洗乾燥機50。$，可獲得以簡單之結構，促進内部空氣與 外部空氣之混合之低成本餐具清洗乾燥機5〇。 於混合通路32之寬度方向之一部份具有設有缺口部37 之面狀體36。缺口部37在混合通路Μ之寬度方向，於混合 流引起亂流。藉此，進行混合通路32之寬度方向之混匯合 體之擾拌在此合通路32全區，促進内部空氣與外部空氣 之勝。結果，促進混合通路32之全區之混合流溫度分布 之穩定化。 20 &外’在以上之說财，就外部空氣通路14之通路截 面與通路15之通路截面呈完全之矩形形狀之結構作了說 明。然而，因作成外部空氣通路“及通路15時之加工之容 易度、故為於各通路截面之角部設置曲率之形狀亦可。為 。又有拔Μ料錐形之梯形形料加工性高之形狀亦可。藉 17 200847987 於長邊設置大曲率或凹凸，形成呈改善流之扁平形狀之扁 平通路亦可。 、、，就具有1個送風機6，以風量分配部u，則個送風機ό 之送風分配至外部空氣通路14及通路I5之結構作了說明。 5然而，亦可為於外部空氣通路14及通路I5各通路分別設置 $風機（圖巾未示），具有控制各送風機之控制部（圖中未示) 、構亦了 如此’為具有各自獨立之送風機與控制部之 結構時’可獲得高性能之作用與效果。 就風量分配部12以阻尼器29之自身重量，封閉外部空 1〇氣通路14或通路丨5，分配風量之結構作了說明。然而，藉 使用彈簧等附勢構件（圖中未示”賦與封閉力，進行風量分 配亦可。此外，藉利用附勢構件之附勢力，可提高風量分 配部12之安裝狀態之自由度。 【圖式簡明]| 15 第1圖係本發明實施形態之餐具清洗乾燥機之結構圖。 第2圖係用於第1圖所示之餐具清洗乾燥機之混合部之 部份截面立體圖。 第3圖係顯示用於第1圖所示之餐具清洗乾燥機之通路 之覓咼比與通路間距離之關係的特性圖。 20 第4A圖係用於第1圖所示之餐具清洗乾燥機之混合部 之部份侧面圖。 第4B圖係用於第1圖所示之餐具清洗乾燥機之另一態 樣之混合部之部份侧面圖。 第5圖係習知餐具清洗乾燥機之結構圖。 18 200847987 【主要元件符號說明】 15…清洗槽内部空氣通路(通路) 1.. .清洗槽 2.. .清洗喷嘴 3.. .清洗泵 4.. .清洗部 5.. .加熱部 6.. .送風機 7.. .排氣口 9.. .乾燥部 10…清洗槽入口 11…清洗槽出口 12.. .風量分配部 13.. .混合部 13a...匯合部 14.. .外部空氣通路 16.. .控制部 17.. .風量控制部 18·.·清洗槽溫度探測部 19.. .排氣溫度探測部 20··.外部空氣溫度探測部 21.. .溫度控制部 22.. .供水閥 23.. .供水管 24.. .排水閥 25.. .排水管 26…殼體 27.. .滑動體 28.. .通氣口 29.. .阻尼器 29a·.·阻尼器 29b...阻尼器 30···下降流部 31…上升流部 3 la...上升流直線部 32…混合通路 33…截面擴大部 34··.攪拌部 35···回流管 36.. .面狀體 37.. .缺口部 50.. .餐具清洗乾燥機 51…被清洗物 52…清洗水 53.. .外部空氣流 54.. .内部空氣流 100.. .餐具清洗乾燥機 19 200847987 101.. .清洗槽 102…清洗喷嘴 103…清洗果 104.··清洗部 105.. .加熱部 106.. .送風機 107··.排氣口 108…排氣輔助部 Ha…高度 Hb…高度 Wa…長邊之長度 Wb…長邊之長度 20FIELD OF THE INVENTION A dishwashing and drying machine that is placed in a kitchen, a cooking place, etc., and dried.

Further, the present invention is not limited to the following embodiments. (Embodiment) 1 Fig. 1 is a configuration diagram of a dish washing and drying machine 50 according to an embodiment of the present invention. As shown in Fig. 1, the dish washing and drying machine 50 includes a washing tank 1, a cleaning unit 4, a heating unit 5, and a drying unit 9. The cleaning tank 1 accommodates the object 51 to be cleaned such as tableware. The cleaning unit 4 and the heating unit 5 are disposed below the cleaning tank 1. The cleaning unit 4 has a β-wash nozzle H edge 3. The cleaning nozzle 2 washes water 52 ft to the object to be cleaned 51, and circulates the washing water 52. The washing pump 3 pressurizes the washing water. The heating unit 5 heats the miscellaneous cut and raises the temperature. Lai Department has 9 money off 6 and exhaust port 7. The blower 6 delivers outside air to the cleaning tank. The exhaust port 7 discharges the moisture in the "wash tank 1" to the outside of the dish washing and drying machine 50. The cleaning tank 1 is not provided with the outside air flowing into the cleaning tank inlet 2 〇 10 (hereinafter referred to as inlet 1 〇) below the cleaning tank 1. A cleaning tank outlet 11 (hereinafter referred to as an outlet 11) for discharging the air in the washing tank 1 is disposed above the inlet 1〇. Further, the internal air of the cleaning tank 1 is the inside air of the cleaning tank (hereinafter referred to as internal air). The outside air of the washing tank 1 or the outside air of the dish washing and drying machine 50 is external air. 7 200847987 10 15 The air volume correcting portion 12 is connected to the downstream side of the blower 6. The external air passage 14 is disposed on the downstream side of the air volume distributing portion 12 and The cleaning tank internal air passage 15 (hereinafter referred to as passage 15) ° the downstream side of the external air passage 14 and the downstream side of the passage 15 merge at the junction portion 13a. The external air passage (4) directs the outside air to the sink 13a 'the passage 15 The inside air is introduced into the junction portion i3a. The junction portion 13 is shouted to the mixing portion 13. The mixing portion 13 mixes the outside 4 working gas with the inside air on the upstream side of the exhaust port 7. The air volume distributing portion 12 distributes the delivery to the external empty passage. 14 and the amount of outside air of the passage 15. Thereby, the air volume distribution unit η changes the flow ratio when the external air of the mixing unit 13 is mixed with the internal air. The passage 1 is provided by the inlet 10, the cleaning tank 1 and The mouth 1 is connected to the junction 13a, that is, the sister 15 is on the downstream side of the air volume distribution 12 and includes the inlet 10 - month washing tank 1 and the outlet nU. The outlet side of the mixing portion 13 is in communication with the exhaust port 7, mixing The population side of =13 is connected to the outside air passage 14 and the outflow. * The control unit 16 has an air volume control correction (hereinafter referred to as a control unit 17) and a temperature f control unit 21 (hereinafter referred to as a control unit 21). The operation unit 17 controls the air volume of the blower 6. The fourth unit 21 has a cleaning tank temperature detecting unit 18 (hereinafter referred to as a detecting unit) and an exhaust temperature detecting unit (hereinafter referred to as a detecting unit 19). The external air temperature detection (4) (hereinafter referred to as 0) is based on the detection temperature detected by the panel measuring portions 18, 19, and 2, and is set as: The detecting unit 18 detects the temperature in the washing tank 1. The detection is again placed on the downstream side of the mixing portion 13 to detect the temperature of the exhaust gas. The detecting portion, = the temperature of the outside air sucked by the measuring fan 6. In addition, the control unit corrects the second portion, has the detecting portion 18, and detects The portion 19 and the detecting portion 2 are required to have the probe portions 18 and 20 200847987 19 and 20 which are indispensable for the performance required for the dish washing and drying machine 5G. The washing tank 1 is connected to the water supply member 23 and the drain pipe 25, The water supply pipe 23 has a water supply valve 22 that controls the supply of the washing water 52. The drain pipe 25 has a drain valve 24 that controls the drain of the washing water 52. The sliding body 27 is disposed to be cleaned from the casing 26. The groove 1 is pulled out. The sliding body 27 is provided with a vent port 28 that communicates with the outside of the dish washing and drying machine 50. The air volume distributing portion 12 has a damper (dumper) that changes the opening degree by the flowing fluid pressure, that is, the wind pressure of the blower 6. 29. The damper 29 is disposed on at least the side of the passage 15 of the external air passage 14 and the passage 15. Thereby, when the wind pressure in the passage 10 is low, the amount of air distribution is set so that the passage on the side of the passage The resistance is greater than the side of the external air passage 14 Therefore, the air volume on the side of the external air passage 14 is set to be larger than the air volume on the side of the passage 15. The air volume distribution unit 12 shown in Fig. 1 has the damper 29a disposed in the external air passage 14 and is disposed in the passage. The damper 29b of the 15. The damper 29 is disposed in both the external air passage 14 and the passage 15. The damper 29 is configured to bear and close with a valve seat (not shown) that is slightly inclined with respect to the vertical plane. Thereby, the damper 29 is brought into a closed state by the weight of the damper 29. That is, the damper 29 is a structure that is closed by its own weight. The fluid pressure at which the damper 29 is started to be opened is set such that the damper 29a is lower than the damper 29b. Therefore, the weight of the damper 20a is lighter than that of the damper 29b. In the state where the damper 29a and the damper 29b are fully opened, the flow distribution to the external air passage 14 and the passage 15 is not determined by the air volume distribution portion 12. The current flow distribution is determined by the total pressure loss from each passage to the exhaust port 7. In the dishwasher cleaning and drying machine 50, the passage pressure loss on the passage 15 side is less than 9 200847987 The passage of the outer port P gas passage 14 side The loss of force. Since the cross-sectional area of the cleaning tank 1 constituting one of the passages is relatively large, it is easy to design the passage resistance of the passage 15 to be smaller than the passage resistance of the external air passage 14. This increases the length of the external air passage 14. Alternatively, the resistance portion (not shown) which is increased in the passage resistance 5 or more at a predetermined flow rate can be easily realized. Further, as the drying operation progresses, the air volume on the passage 15 side is opened when the damper 29b is fully opened during the operation. The amount of wind is larger than that on the side of the outside air passage 14. The passage 15 has a downflow portion 30 and an upflow portion 31. The downflow portion 刈 causes the internal air flow to flow from the outlet 11 to the lower side. The upflow portion 31 reverses the internal air flow from the lowermost end of the downflow portion 1〇3〇. The junction portion 13a is formed such that the upflow portion 31 merges with the outside air passage 14. Further, the ascending flow portion 31 has an upward flow straight portion 31a in which the passage 15 extends in the linear direction. The outer air passage 14 is merged with the passage 15 by the side of the upward flow straight portion 31a to form the joint portion 13a. The mixing portion 13 has a mixing passage 32 in which a mixed flow of internal air and external air flows, on the downstream side of the junction portion 13 & Further, the mixing passage 32 has a cross-sectional enlarged portion 33 (hereinafter referred to as an enlarged portion 33) and a stirring portion 34. The enlarged portion 33 is formed such that the passage cross-sectional area of the mixing passage 32 is enlarged. The disturbing portion 34 dreams to stir the flow of the inside air and the outside air to promote the mixing of the inside air and the outside air 20. Further, a return pipe 35 is provided below the downflow portion 3A. One end of the return pipe 35 communicates with the lower portion of the downflow portion 30, and the other end communicates with the inside of the washing tank. Thereby, the return pipe 35 discharges the washing water 52 flowing from the outlet to the downflow portion 3 to the washing tank 1. Fig. 2 is a partial cross-sectional perspective of the confluence portion 13a shown in Fig. 1 200847987 - 胄. Further, Fig. 2 is a view showing the structure around the junction portion, and a part of the cross section is cut to show the internal structure. As shown in Fig. 2, the passage Μ and the outer air passage Η are formed on the long side of the passage shape of the rectangular cross-shaped shape having a substantially wide aspect ratio and joined to each other at the junction portion 。. .^ In the outer section of the sink (4) 13a, the passage section of the air material 14 has a long side with a width Wa and a short side with a height Ha having a rectangular cross-sectional shape. The aspect ratio of the cross section of the external line path 14 is ARa. In the confluence section, the it_face of the secret I5 is (4) the width Wb, and the short material height is about the shape of the rectangular section. The aspect ratio of the passage section of the passage 15 is = = peach W / Hb. Thus, the external air passages 14 and the passages 15 are all formed in a flat shape, and are disposed such that the long sides Wa and Wb of each other are joined to each other. ~, the external air passage Μ and the passage 15 respectively form a flat passage. The flap portion 34 is formed by a % of the planar body protruding from the mixing passage 32. The surface-like body 36 extends in the width direction of the joint passage 32, and is disposed at a portion of the width direction of the mixing passage 15 (four)-shaped body 36, and is provided with a notch portion 37 formed by reducing the amount of protrusion. In the following, the sliding body 27 is first pulled out from the installation body 26, and the object to be cleaned 51 is taken up in the washing tank 1 as in the operation and operation of the dish washing and drying machine 5 configured as described above. After the object to be cleaned 51 is stored in the washing tank 1, the slide body 27 is returned to the original position, and the cleaning of the object to be cleaned 51 is started. When the cleaning operation is started, the water supply valve 22 is opened, and water is supplied from the water supply pipe 23 to the cleaning tank. When a predetermined amount of water supply is performed to the washing tank 1, the water supply valve 22 is closed to stop the water supply. Then, the π washing water 52 of warm water is ejected from the washing nozzle 2 by the action of the heating unit 5 and the cleaning unit 4, and is sprayed on the object 51 to be cleaned. The washing water sprayed by the cleaning 51 11 200847987 52 is broken, and the ball is sprayed to the object 51 to be cleaned. The cleaning nozzle 2 is rotated by the reaction force of the washing water a. Thereby, the washing water is spread over the corners of the plurality of articles to be cleaned 51 to improve the cleaning performance. When the washing operation is completed, the drain valve 24 is opened to discharge the washing water 52 from the drain pipe 25 to the outside of the casing 26. When the drain is 5 bundles, the drain valve 24 is closed. The cleaning using the heating unit 5 to clean the washing water 52 which is warm water will be described. However, the washing water 52 is not limited to warm water, and when the dirt of the object to be cleaned 51 is small, the heating unit 5 is not operated, and the washing water of the water supply temperature is washed. When the dirt of the object to be cleaned is strong, a detergent (not shown) may be added to the washing water 52 to perform cleaning. After the alpha wash operation, a scrubbing operation is then performed. In the washing operation, the detergent is not placed, and the water is supplied in the same manner as the washing operation. The washing unit 2 and the washing unit 4 act to eject the washing water brother which is warm water from the washing nozzle 2, and the laundry is cleaned. 51 injection. The washing water 52 sprayed on the object to be cleaned 51 circulates in the same manner as in the washing operation, and is sprayed on the object to be cleaned 51. In order to carry out the drying operation after the washing operation, it is preferable to heat the object to be cleaned 51 in the brushing operation, and to use the high-temperature washing water 52 of about 7 叱 to Saki, and to perform the sterilizing treatment when performing the washing operation. Further, the drying operation system causes the object to be cleaned 51 to run in a dry state. After the end of the scrubbing operation, the washing water in the washing tank 1 is discharged in the same manner as in the end of the month washing operation. In the subsequent drying operation, the air in the washing tank 1 which is formed into a high temperature and high humidity by the washing operation is discharged, and the object to be cleaned 51 is dried. Therefore, the blower 6 is operated, and the air volume distributing portion 12 operates, and the material portion air is branched to the external air passage 14 and the passage 15. The shunted outside air is sent to the mix: 12 200847987 - Part 13 and Washing Tank 1. First, at the beginning of the drying operation, the internal air is preferentially cooled. Therefore, the amount of blown air of the blower 6 is set to a small amount, and the damper 29a is turned on. Thereby, the amount of wind on the side of the outside air passage 14 is larger than the amount of wind on the side of the passage 15 . As a result, the external air flow 53 in the wind and the internal air flow 54 having a small amount of air and high temperature and high humidity are merged and mixed at the junction portion 13a to promote the cooling of the internal air. Further, the flow velocity of the mixed flow after the air inside the enlarged portion 33 is merged with the outside air is decelerated to promote the removal of moisture which is condensed by the cooling of the internal air. Further, in the agitating portion 34, the internal air is uniformly mixed with the outside air, and after the cooling and the water removal of the internal air are performed, the exhaust gas is discharged from the exhaust port 7 to the outside of the dish washing and drying machine 5. Then, when the drying operation is performed to reduce the temperature in the cleaning tank, the drying priority in the cleaning tank 1 is performed. Therefore, the air volume of the blower 6 is increased. The dampers 29a, 29b are in a fully open state. When the dampers 29a, 29b are opened, the distribution of the air volume of the external air passage 14 and the passage 15 is controlled by the passage resistance, and the air volume on the passage 15 side is distributed more than the air volume on the outer air passage 14 side. Thereby, the air supply for the main purpose of drying is performed. Thus, the opening degree of the damper 29 for the air supply amount of the air blower 6 is changed, and the distribution of the external air passage 14 and the passage 15 is performed in accordance with the fluid pressure. As described above, the exhaust gas which has been cooled and dehydrated flows out from the exhaust port 7. As a result, a dish washing and drying machine 50 which realizes simplification of the structure and low cost can be obtained. In particular, when the washing operation using the high-temperature washing water 52 is performed, the high-temperature and high-humidity air in the washing tank 1 is not directly discharged from the exhaust port 7, and the drying is performed mainly at the beginning of the drying operation, and drying is performed. Running. 13 200847987 Therefore, the control unit 17 controls the blower 6 so that the air volume on the side of the outside air passage 14 is larger than the amount of wind on the side of the passage 15 . In the dish washing and drying machine 50 of the present invention, the outside air is mixed with the high-temperature and high-humidity internal air, and the internal air is cooled 5 and the moisture contained in the internal air is condensed. Therefore, when the internal air and the outside air are required to be uniformly and rapidly mixed, the structure of the mixing portion 13 and the structure of the confluence portion 13a function extremely efficiently. Fig. 3 is a characteristic diagram showing the relationship between the aspect ratio of the passage cross section and the distance between the passages when the cross-sectional area of the passage is assumed to be a predetermined constant value and the two passages are arranged side by side. Further, in Fig. 3, an example of the cross-sectional area of the passage is 1 mm 2 . Also, the thickness of the walls of the two passages is assumed to be zero. As shown in Fig. 3, the closer the aspect ratio of the rectangular cross section, the closer the two passages, that is, the two fluids can be disposed. For example, when the aspect ratio is 4, the distance between the paths can be substantially halved compared to the aspect ratio 1. Therefore, when the aspect ratio 15 is 4 or more, the arrangement of the two flow paths is close to each other, and when the passage walls disappear and merge, it is suitable as a condition for mixing two fluids. As described above, the passage 15 for introducing the internal air and the external air passage 导入 for introducing the outside air in the dish washer-dryer 50 of the present embodiment have a rectangular cross section having a substantially large aspect ratio, and are joined to the long side of the cross section of the passage. 2〇 merge to form the junction 13a. Thereby, a mixture of the thinner streams can be obtained, and the mixing promotion and the equal mixing of the entire flow region can be performed. Further, during the drying operation, the internal air in the high-temperature and high-humidity cleaning tank 1 is surely mixed with a sufficient amount of outside air in the air of the small pear. Thereby, the internal air is rapidly cooled. As a result, the exhaust gas which is surely reduced in temperature and humidity is obtained, and the cleaning and drying machine 50 for realizing the prevention of the hot air 14 200847987 and the miniaturization of the machine is realized. For the passage extending in the straight line direction ^ ^ 15 'The external air passage 14 is formed by the junction of the side of the passage I5. In particular, the air volume of the external air is larger than the air volume of the internal air. At the beginning of the beginning, the main part of the air is to reduce the oxygen and the degree of the gas, and the drying is carried out.., ._ ^, the outside air is bent at the junction 13a, causing disorder. Thereby, the stirring action of the external air to the internal air is generated. Therefore, the outside air can sufficiently reduce the mixing of the internal air and the outside air. As a result, the unevenness of the 10 15 20 is made such that the internal air in the mixing passage 32 is combined with the external helium gas to distribute the material Γ section == the aspect ratio of the road section and the passage 4 of the external air passage 14 or more. Thereby, the internal air flowing through the passage 15 is managed. The temperature of the external air fluid flow of the ancient contact passage 14 is double. When the fluid flow is thin, the energy can be ^ 〇 ^w , and the inside air is mixed with the outside air to promote the internal air and the external air in the flow region where the flow rate is slow, and it is also possible to treat the air at the right side. The long side length of the passage section of the passage section of the internal air and the external external air passage is mixed with the passage 15 in a continual manner. Therefore, as shown in FIG. 2 and FIG. 4, the outer side of the cross section and the long side of the passage cross section of the passage 15 are arranged as follows: = the outer rolling passage 14 and the passage 15 The space, but dare to be small. As a result, the neighboring, raw, and Qingna·:: types are mixed. In addition, the fourth drawing is a partial side view of the fitting portion 13 from the / month washing tank. As shown on the first side, the outer side of the outer air passage (4) is the long side of the wear surface. 200847987 The length Wa can also be greater than the length of the surface of the 15th. That is, it is also possible to have a relationship of Wa > Wb. X, the long side of the passage section of the passage 15 may be disposed inside the long side of the passage section of the external air passage 14. The long side of the passage surface of the passage 15 is disposed inside the long side of the cross section of the external air passage 14 and is capable of reliably supplying the outside air in the longitudinal direction (width direction) of the internal air of high temperature and high humidity. Mix the light air with the outside air. As a result, in the mixed flow of the inside air and the outside air, it is possible to prevent the portion of the internal air from being unmixed, and to stabilize the exhaust gas temperature. Further, the Fig. 4B is a partial side view when the mixing portion 13 is viewed from the washing tank H. The passage 15 has an upward flow portion 31 that flows from the outlet 11 to the lower portion to the downflow portion 30 and on the downstream side of the descending flow portion to reverse the fluid upward. The outer passage 14 is brought into contact with the ascending flow portion 31 to form a junction portion. As a result, when the amount of air in the internal air is small, the outside air heated by the internal air rises, and a flow toward the exhaust port 7 side is generated, thereby forming an upward flow that reduces the fluctuation of the flow. The result is that the upflow after mixing the internal air with the outside air is also stabilized. By increasing the production, the upward flow of the movement can reduce the temperature unevenness of the mixed flow of internal air and external air caused by the fluctuation of the internal air. Further, a downflow portion 3A is provided on the upstream side of the upflow portion 31. Thereby, the cleaning water hopper can be prevented from entering the external air passage 20 14 during the cleaning operation or the washing operation. In addition, the internal air generated by natural convection can be reduced to the exhaust port 7 . On the downstream side of the port u|U3a, there is an enlarged portion 33 having a large passage cross-sectional area. As a result, in the enlarged portion 33, the flow velocity of the mixed flow after the internal air and the external line are merged is slow, and a flow of the vortex is generated in the enlarged portion 33. As a result, the flow of the mixed flow fluctuates and the mixing is promoted. At the same time, the elimination of moisture condensation due to the cooling of the internal air of 16 200847987 is promoted. Downstream (4) downstream of the confluence portion 13a is a stirring portion 34 which mixes the air of the (four) portion air with the outside air to promote mixing of the inside air and the outside air. This allows for a strong mixing of internal air and external air. Because it promotes the mixing of internal air and outside air, it can mix the internal air and the outside air equally. Further, atomization of water generated by cooling the inside air can be promoted. The tonnage vessel extending in the width direction of the mixing passage 32 protrudes to form the mixing portion 34. Thereby, it is possible to achieve a mixture of internal air and external air. X, the agitating portion 34 is formed integrally with the wall of the mixing passage 32. By this, the (four)-aged egg-knotted, low-cost tableware cleaning and drying machine 50 can be used. $, a low-cost dishwashing and drying machine with a simple structure that promotes the mixing of internal air and outside air. A planar body 36 having a notch portion 37 is provided in a portion of the width direction of the mixing passage 32. The notch portion 37 causes turbulence in the mixed flow in the width direction of the mixing passage. Thereby, the mixing of the mixed passages in the width direction of the mixing passage 32 is mixed in the entire area of the combined passage 32 to promote the victory of the inside air and the outside air. As a result, the stabilization of the mixed flow temperature distribution of the entire region of the mixed passage 32 is promoted. In the above, the structure of the passage of the outer air passage 14 and the passage of the passage 15 in a completely rectangular shape are explained. However, since the outer air passage "is easy to process when the passage 15 is formed, the shape of the corner portion of each passage cross section may be set to a curvature. The trapezoidal shape of the taper material is high in workability. The shape may also be. By using 2008/07987, a large curvature or unevenness is formed on the long side to form a flat passage having a flat shape for improving the flow. Then, one blower 6 is provided, and the air distribution unit u is provided with a blower ό The structure in which the air supply is distributed to the external air passage 14 and the passage I5 is explained. However, it is also possible to provide a fan (not shown) for each passage of the external air passage 14 and the passage I5, and has control for controlling each blower. The part (not shown) and the structure have the effect and effect of obtaining high performance when the structure is independent of the blower and the control unit. The air volume distribution unit 12 closes the outside with the weight of the damper 29 The structure of the air distribution is explained in the air/air passage 14 or the passage 丨5. However, it is also possible to distribute the air volume by using a retaining member such as a spring (not shown) to impart a closing force. By using the attached force of the attached member, the degree of freedom of the installation state of the air volume distribution unit 12 can be improved.
