如第1圖及第2圖所示，餐具清洗機60具有餐具清洗機 15 本體1(以下也單記為「本體」）。本體1具有：由側方觀看時 其外廓形狀分別呈大略垂直狀之前面部la及背面部lb、及 位於前面部la及背面部lb之間，形成上方呈凸狀之大略圓 弧形狀之圓弧狀部lc。又，本體1於其前面（第1圖及第2圖 中左側）具有大略平面形狀之平面部Id。 20 餐具清洗機60於本體1内部設有一可收容用以收納餐 具等之被洗淨物之餐具籃3之洗淨槽2。如第1圖所示，洗淨 槽2之上部沿著本體1上部之圓弧狀部lc之内面，由上面到 背面（第1圖中右側）形成朝上方凸出之大略圓弧形狀。 又，洗淨槽2具有由前面到上面開口之開口部4，及用 10 1323165 15。又，洗淨槽2下部設有控制裝置16，可控制洗淨泵14或 加熱器15等。 以下，進一步詳細說明餐具清洗機6〇之門體5的構成。 如第3圖所示，開口部4形成為包含本體丨之前面部la、 5 及設置成由前面部la到上面朝外方膨起之圓弧狀部ic之一 部份。如第2圖所示，開口部4之上端部39係位於本體1之圓 弧狀部lc上面之頂部17附近，在本體1之上部面積中，前面 部la側之大略一半的面積形成開口部4(又，線分c係通過頂 部17之垂直線，開口部4之上端部39係位於其垂直線之附 10 近）。 以下，更進一步詳細說明上門體6及下門體7之開關構 造。第4圖係顯示餐具清洗機60之上門體6及下門體7之開關 構造之側面圖。 首先’如第4圖所示，上門體6與下門體7之卡合部18 15 設置於形成於本體1前面之平面部Id，並藉由設置於上門體 6側之岔封構件21 '及設置於下門體7側之密封接抵部22， 上門體6與下門體7之間的間隙可密封不透水。 在此’第4圖係顯示上門體6及下門體7關閉之狀態，第 3圖係如前所述，顯示上門體6及下門體7打開之狀態。以 20下’合併使用第3圖及第4圖進行說明。 上門體6設有上門體支持部23，下門體7設有下門體支 持部24 ^ 上門體支持部23係受設置於洗淨槽2側面之上門體旋 動轴25支持而可對本體自由旋動，又，下門體支持部24係 12 檔止接抵部36 ’上門體6及下門體7會停止’成為無法再往 上移動之開放狀態。 又，本實施形態之餐具清洗機60中’如第3圖及第5圖 所示，於本體1之背面部lb之外側設有盛水部40，而可在門 體5打開之狀態下，即使水滴41由上門體6之前端部62滴下 到本體1外側也可被盛接住。 第5圖係顯示本發明之第1實施形態之餐具清洗機6 〇之 盛水部40之構成之部分側截面圖。第5A圖係顯示關閉上門 體6時之狀態’第5B圖係顯示打開上門體6之開放狀態。如 第5B圖所示’由上門體6之内側滴下到本體1外側之水滴 4卜及由上門體6之前端部62滴下之水滴41皆可由盛水部4〇 盛接住。 其次，說明本實施形態之餐具清洗機6〇之動作及作用。 一般而言，設置餐具清洗機60時，有沿著廚房的侧壁 將餐具清洗機60之正面朝面前放置的型態（正面放置）、及 其側面朝面前放置之情況(縱向放置）。最近的廚房—般係將 用以集中控制水槽或供熱水器等供熱水設備之控制器設置 於廚房的側壁。 若將習知之餐具清洗機120設置於廚房，控制器設置於 較餐具清洗機120之本體101高的位置時雖然沒有問題但 若控制器設置於較讀1()1缝時，為了確保設置於控制器 之顯示部的視認性或開關類的操作性，由於必須將餐具清 洗機120設置使之與壁面距離某個程度而取決於場所因 此有損在廚房的作業性。而且，當控制器設置於更低的位 1323165 弧狀，因此可增加往上面之洗淨水量，增加由上面灌注到 餐具之洗淨水，可確實清洗附著於餐具表面之汚垢。 又，本實施形態之餐具清洗機60中，其開口部4係包 含：本體1之前面部la、及設計成由前面部la到上面往外方 5膨起之圓弧狀部lc。藉此’可輕易由餐具籃3放置與取出餐 具，可提升餐具之放置性。 更進一步，藉由將設置於洗淨槽2之上面之開口部4之 上端部39形成為位在圓弧狀部lc之頂部π附近，可為一使 本體1之上部面積之大略半部分開口之構成。因此，可看到 10 上段籃9之内部，並且可輕易進行餐具之取放。 又，餐具清洗機60中，係如第1圖所示，使餐具籃3構 成為盤類50之重心位置、及圓弧狀部lc之圓弧之中心位置 分別到本體1前面之距離大略相等。藉此，即使係大型碗盤 也可使之不接觸到洗淨槽2之開口部4之邊緣而可輕易取 15 放。 本實施形態之餐具清洗機60中，係由使洗淨槽2之前面 與上面開放而形成開口部4»因此，覆蓋該開口部4之門體5 相較於具有相同程度之本體尺寸之習知之餐具清洗機120 而言上下方向較長。因此，若為使用單門向上開啟之構成 20時，門會造成妨礙使得難以由上方放置或取出餐具。又’ 若為使用單門向下開啟之構成時，若正面放置’則大扇門 會由本體朝面前打開，廚房流理台上之料理空間會變得狹 小，若縱向放置的話，則門會檔到水龍頭，而有門無法完 全打開的可能性。 〔5) 17 1323165 然而，若根據本實施形態之餐具清洗機6〇，門體5由上 門體6及下門體7二扇門所構成’於由洗淨槽2之前面到上面 所設置之開口部4之平面部Id形成門體5之分割位置、即卡 合部18。藉此，可減少打開開口部4時之下門體7朝本體 5 方之突出量，因此可縮小在正面放置時於本體1前方所需要 之深度尺寸。又，縱向放置時，即使水龍頭等存在於本體1 附近時，也可降低下門體7抵觸到水龍頭之可能性，因此$ 提高本體1之設置性。 一般而言，若將餐具清洗機60設置於較狹小之厨房之 10 洗滌側時，相較於將洗淨槽2之開口部4放置於使用者之相 對面之正面放置，多半係如第3圖所示於廚房之右或左側之 洗滌側縱向設置。 如此縱向放置的情況下，當打開門體5取放餐具時，係 由開口部4之斜上方進行之，但本發明之上門體支持部23係 15形成為朝上方凸出之大略圓弧形狀，而可在上門體6關閉時 收納於蓋體37内，並且在打開上門體6時，上門體支持部23 與圓弧狀部lc交錯之位置會變位到較開口部4之上端部39 之後方。即，由於係上門體支持部23不會妨礙到開口部4之 構成，因此使用者的視線不會被遮住，而可提高餐具之放 2〇 置性。 又本實施形態之餐具清洗機6〇中，於上門體6設有用 以收納上門體支持部23之蓋體37，在門體5關閉時，上門體 支持部23由本體i突出之部分收納於蓋體37。又上門體支 持。P 23未由本體1突出之部分也可由本體側面主體部犯覆 18 (S > 1323165 蓋。藉此’由於上門體支持部23與上門體連動錢動袖^等 機構零件不會露出於本體外，因此可防止塵埃或污垢等里 物卡入且堆積於上門體旋動轴25或上門體連動旋動轴^等 之回動軸，並可使門體5滑順地進行開關。 5 又’由於移動軸27及移動溝28也可藉由本體側面主體 部38而不露出於本體外，因此亦可防止塵埃或污垢等異物 進入移動軸27與移動溝28内。 又，本實施形態之餐具清洗機60中，於本體丨之背面部 設有盛水部40。因此，在門體5開關時，即使水滴41由上門 10 體6之内面或前端部62而滴下到為大略圓弧狀之本體！的外 面’也可藉由盛水部40而盛接住。藉此，由於水滴41不會 滴下於洗滌槽70 (參照第3圖），因此可保持清潔，並可防 止水滴41附著於配設於製品之背面部之電源線部（未圖 示），提南安全性。 15 (第2實施形態） 其次，說明本發明之第2實施形態之餐具清洗機。第6 圖係顯示本發明之第2實施形態之餐具清洗機72之構成之 側截面圖。 如第6圖所示，餐具清洗機72之構成與本發明之第1實 20 施形態之餐具清洗機60不同處在於，在本體1之背面部lb所 設置之盛水部40之底面的一部，設置與洗淨槽2相通之管 45 ° 餐具清洗機72進一步於管45到達洗淨槽2之部分配設 閥42，並且貯存於盛水部40之水滴41會流返於洗淨槽2内。 19 (S ) 1323165 洗淨槽2或排水口。 因此，不會有水滴41由盛水部40溢出之情況，而可提 昇安全性。又，藉於底面部43設置坡度，由於本體1之背面 之盛水部40不會有水滴41残留，因此可保持餐具清洗機75 5 之清潔。 (第5實施形態） 其次，說明本發明之第5實施型態之餐具清洗機。第10 圖係顯示本發明之第5實施形態之餐具清洗機80之構成之 側面圖。 10 如第10圖所示，本實施形態之餐具清洗機80與第1實施 形態之餐具清洗機60不同之處在於，於上門體6之前端部62 内側，可使用鉤嵌合或挾入或接著等方式安裝盛水體82。 第11圖係顯示本實施形態之餐具清洗機80之盛水體82之構 成之截面圖。第11A圖係顯示關閉上門體6時之狀態，第11B 15 圖係顯示打開上門體6時之狀態。 一般而言，當餐具清洗機中在洗淨途中等打開門體之 情況下，附著於上門體内壁之水滴會因為上門體在全開狀 態下停止時之衝擊而由上門體飛散到本體之背面方向。 然而，本實施形態之餐具清洗機80中，該飛散之水滴 20 42可被安裝於上門體6之盛水體82盛接住。藉此，可防止水 滴42附著於背面之壁，並且飛入位於本體1背面之插頭等裝 置，因此可經常保持洗滌槽70周邊的清潔，並可降低漏電 等之危險性，提昇安全性。 又，藉由將盛水體82設置於較覆蓋上門體6之開口部4 22 1323165 之部分之上面、即更前端部分，可更為有效地防止附著於 門體5之水滴42的飛散。 又，在餐具清洗機80之構成中，當想要令關閉門體5 之狀態下上門體6與本體1之間的間隙41更狹小時，可以樹 5 脂等軟質材料形成盛水體82,藉此即使藉由門體5之開關動 作而與本體1抵接，也不會對門體5之開關動作有所影響， 且外觀也較為美觀。 進一步，若欲以金屬等硬質材料形成餐具清洗機80之 盛水體8 2，且若藉由設計刻意確保一在門體5關閉之狀態下 10 上門體6與本體1不會干擾之間隙41，則不會影響門體5之開 關動作，可於上門體6與本體1之間實現所期望之寬度的間 隙41。藉此，可防止因為手等進入間隙41，強硬拉開上門 體6之前端部62等而使餐具清洗機80為不安全之模式，可提 升安全性。 15 (第6實施形態） 其次說明第6實施形態之餐具清洗機。第12圖係說明本 發明之第6實施形態之餐具清洗機84之盛水體83之構成之 側截面圖。 本實施形態之餐具清洗機84係如第12圖所示，盛水體 20 83與上門體6係形成為一體。又，由於其他構成要素與第5 實施形態之餐具清洗機80相同，因此省略其說明。 藉由如此之構成，可減少構成上門體6之零件數，使成 本降低，並可省去來自嵌合部之水浸入或零件之嵌合強度 等之品質降低之主要因素，因此可提升餐具清洗機84之品 23 1323165 第10圖係顯示本發明第5實施型態之餐具清洗機之構 成之側面圖。 第11圖係顯示同一餐具清洗機之盛水體之構成之側截 面圖。 5 第12圖係用以說明本發明之第6實施形態之餐具清洗 機之盛水體之構成之側截面圖。 第13圖係顯示習知之餐具清洗機之構成之側截面圖。 【主要元件符號說明】 1,101...餐具清洗機本體

Even if the water droplet 41 is dropped from the front end portion 62 of the upper door body 6 to the outside of the body 1, it can be caught. Fig. 5 is a partial side cross-sectional view showing the configuration of the water containing portion 40 of the dishwasher 6 according to the first embodiment of the present invention. Fig. 5A shows the state when the upper door body 6 is closed. Fig. 5B shows the open state in which the upper door body 6 is opened. As shown in Fig. 5B, the water droplets 4 dropped from the inner side of the upper door body 6 to the outside of the main body 1 and the water droplets 41 dropped by the front end portion 62 of the upper door body 6 can be caught by the water holding portion 4. Next, the operation and action of the dishwasher 6 of the present embodiment will be described. In general, when the dishwasher 60 is provided, there is a case where the front side of the dishwasher 60 is placed facing the front along the side wall of the kitchen (front side), and the side thereof is placed facing the front (longitudinal placement). The most recent kitchens are generally equipped with a controller for centrally controlling the water supply or water heaters such as water heaters on the side walls of the kitchen. If the conventional dishwasher 120 is installed in the kitchen, the controller is disposed at a position higher than the body 101 of the dishwasher 120, although there is no problem, if the controller is installed in the 1st (1) slit, in order to ensure the setting is The visibility of the display portion of the controller or the operability of the switch type must be such that the dishwasher 120 must be placed at a certain distance from the wall surface depending on the location, thereby impairing the workability in the kitchen. Moreover, when the controller is arranged in a lower position 1323165 arc, the amount of washing water to the top can be increased, and the washing water poured into the tableware can be added to surely clean the dirt adhering to the surface of the tableware. Further, in the dishwasher 60 of the present embodiment, the opening portion 4 includes a front surface la of the main body 1 and an arcuate portion lc which is designed to be swollen from the front portion 1a to the outer surface 5. By this, it is easy to place and remove the tableware from the cutlery basket 3, thereby enhancing the placement of the tableware. Further, by forming the upper end portion 39 of the opening portion 4 provided on the upper surface of the cleaning tank 2 in the vicinity of the top π of the arc-shaped portion lc, it is possible to open a large portion of the upper portion of the body 1 The composition. Therefore, the interior of the upper basket 9 can be seen in 10, and the tableware can be easily taken. Further, in the dishwasher 60, as shown in Fig. 1, the dish basket 3 is configured such that the center of gravity of the disk 50 and the center of the arc of the arcuate portion lc are substantially equal to the front of the body 1. . Thereby, even if the large bowl is placed, it can be easily touched without coming into contact with the edge of the opening portion 4 of the washing tank 2. In the dishwasher 60 of the present embodiment, the opening portion 4 is formed by opening the front surface of the cleaning tank 2 and the upper surface thereof. Therefore, the door body 5 covering the opening portion 4 is compared with the body size having the same degree. The tableware washing machine 120 is known to have a long vertical direction. Therefore, if the composition 20 is opened up using a single door, the door may cause obstruction such that it is difficult to place or take out the dishes from above. In addition, if the structure of using a single door to open downwards, if the front side is placed, the large door will open from the main body toward the front, and the cooking space on the kitchen counter will become narrow. If placed vertically, the door will be closed. The gear is to the faucet, and there is a possibility that the door cannot be fully opened. [5] 17 1323165 However, according to the dishwasher 6〇 of the present embodiment, the door body 5 is composed of the upper door body 6 and the lower door body 7 and two doors, which are disposed from the front surface of the cleaning tank 2 to the upper surface. The plane portion Id of the opening portion 4 forms a division position of the door body 5, that is, the engagement portion 18. Thereby, the amount of protrusion of the door body 7 toward the body 5 when the opening portion 4 is opened can be reduced, so that the depth dimension required in front of the body 1 when placed on the front side can be reduced. Further, when placed in the longitudinal direction, even if a faucet or the like is present in the vicinity of the main body 1, the possibility that the lower door body 7 is in contact with the faucet can be reduced, so that the installability of the main body 1 is improved. In general, when the dishwasher 60 is placed on the 10 washing side of the narrow kitchen, it is placed on the front side of the opposite side of the user with respect to the opening 4 of the washing tank 2. The figure shows the vertical side of the washing side on the right or left side of the kitchen. In the case of such a vertical position, when the door body 5 is opened and the tableware is opened, it is performed obliquely upward from the opening portion 4, but the door body supporting portion 23 of the present invention is formed into a substantially circular arc shape which protrudes upward. When the upper door body 6 is closed, it can be accommodated in the lid body 37, and when the upper door body 6 is opened, the position where the upper door body supporting portion 23 is interlaced with the arc-shaped portion lc is displaced to the upper end portion 39 of the opening portion 4. After that. That is, since the door support portion 23 does not interfere with the configuration of the opening portion 4, the user's line of sight is not blocked, and the placement of the tableware can be improved. Further, in the dishwasher 6 of the present embodiment, the upper door body 6 is provided with a lid body 37 for accommodating the upper door body supporting portion 23, and when the door body 5 is closed, the upper door body supporting portion 23 is housed by the main body i. Cover 37. Also supported by the door. The portion of the P 23 that is not protruded from the main body 1 can also be covered by the main body side body portion 18 (S > 1323165 cover. By this, the mechanical parts such as the upper door body support portion 23 and the upper door body are not exposed to the present. In vitro, it is possible to prevent dust or dirt from getting caught in the door and to accumulate on the return shaft of the upper door body rotating shaft 25 or the upper door body, and to smoothly switch the door body 5 smoothly. Since the moving shaft 27 and the moving groove 28 are not exposed to the outside of the body by the main body side main body portion 38, foreign matter such as dust or dirt can be prevented from entering the moving shaft 27 and the moving groove 28. Further, in the present embodiment In the dishwasher 60, the water holding portion 40 is provided on the back portion of the main body 。. Therefore, even when the door body 5 is opened or closed, the water droplets 41 are dripped from the inner surface or the front end portion 62 of the upper door 10 body 6 to a substantially arc shape. The outer portion of the body can also be held by the water containing portion 40. Thereby, since the water droplets 41 do not drip in the washing tub 70 (refer to FIG. 3), the cleaning can be kept clean and the water droplets 41 can be prevented from adhering. In the power cord section of the back part of the product (not shown) (Second Embodiment) Next, a dishwasher according to a second embodiment of the present invention will be described. Fig. 6 is a side cross-sectional view showing the configuration of the dishwasher 72 according to the second embodiment of the present invention. As shown in Fig. 6, the configuration of the dishwasher 72 differs from the dishwasher 60 of the first embodiment of the present invention in that the bottom surface of the water containing portion 40 provided on the back portion lb of the main body 1 is provided. One portion is provided with a tube 45° communicating with the washing tank 2, and the dishwasher 72 further distributes the valve 42 to the portion of the tube 45 that reaches the washing tank 2, and the water droplet 41 stored in the water containing portion 40 flows back to the washing. In the clean tank 2, 19 (S) 1323165, the tank 2 or the drain port is cleaned. Therefore, there is no possibility that the water droplets 41 overflow from the water containing portion 40, and the safety can be improved. Further, the slope is set by the bottom portion 43. Since the water holding portion 40 on the back surface of the main body 1 does not have the water droplets 41 remaining, the cleaning of the dishwasher 75 5 can be maintained. (Fifth Embodiment) Next, a dishwasher according to a fifth embodiment of the present invention will be described. Fig. 10 is a view showing the dishwasher 80 of the fifth embodiment of the present invention. As shown in Fig. 10, the dishwasher 80 of the present embodiment is different from the dishwasher 60 of the first embodiment in that a hooking can be used inside the front end portion 62 of the upper door body 6. The water-containing body 82 is attached or slid or the like. Fig. 11 is a cross-sectional view showing the configuration of the water holding body 82 of the dishwasher 80 of the present embodiment. Fig. 11A shows the state when the upper door body 6 is closed. 11B 15 The figure shows the state when the upper door body 6 is opened. Generally speaking, when the door body is opened in the washing machine in the middle of the washing machine, the water droplets attached to the inner wall of the upper door will be stopped because the upper door body is fully open. The impact of the time is scattered by the upper door to the back of the body. However, in the dishwasher 80 of the present embodiment, the scattered water droplets 20 42 can be caught by the water holding body 82 attached to the upper door body 6. Thereby, it is possible to prevent the water droplets 42 from adhering to the wall of the back surface and to fly into the device such as the plug located on the back surface of the main body 1, so that the periphery of the washing tub 70 can be kept clean at all times, and the risk of electric leakage or the like can be reduced, and safety can be improved. Further, by providing the water containing body 82 on the upper surface of the portion covering the opening portion 4 22 1323165 of the upper door body 6, i.e., the front end portion, the scattering of the water droplets 42 adhering to the door body 5 can be more effectively prevented. Further, in the configuration of the dishwasher 80, when the gap 41 between the upper door body 6 and the main body 1 is made to be narrower when the door body 5 is closed, the water body 82 can be formed of a soft material such as a tree grease. Even if it is in contact with the main body 1 by the switching operation of the door body 5, it does not affect the switching operation of the door body 5, and the appearance is also beautiful. Further, if it is desired to form the water holding body 8 2 of the dishwasher 80 with a hard material such as metal, and if it is designed to ensure a gap 41 in which the door body 6 and the body 1 do not interfere with each other in the state where the door body 5 is closed, The switching action of the door body 5 is not affected, and a gap 41 of a desired width can be realized between the upper door body 6 and the body 1. Thereby, it is possible to prevent the dishwasher 80 from being unsafe because the hand or the like enters the gap 41, and the front end portion 62 of the upper door body 6 is forcibly opened, and the safety can be improved. (Sixth embodiment) Next, a dishwasher of a sixth embodiment will be described. Fig. 12 is a side cross-sectional view showing the configuration of the water holding body 83 of the dishwasher 84 according to the sixth embodiment of the present invention. In the dishwasher 101 of the present embodiment, as shown in Fig. 12, the water containing body 20 83 and the upper door body 6 are integrally formed. Further, since the other components are the same as those of the dishwasher 80 of the fifth embodiment, the description thereof will be omitted. According to this configuration, the number of parts constituting the upper door body 6 can be reduced, the cost can be reduced, and the main factor of the quality of the water intrusion from the fitting portion or the fitting strength of the fitting can be eliminated, so that the tableware can be cleaned.
