Description
本發明係有關於一種使用洗滌水洗滌餐具等之餐具清洗機。The present invention relates to a dishwasher for washing dishes and the like using washing water.
習知之餐具清洗機之洗滌噴嘴的結構如第11、12圖所示(例如，參照專利文獻1)。以下，針對其結構進行說明。如圖所示，於洗滌槽內噴射洗滌水並可自由旋轉的洗滌噴嘴101以旋轉軸102為中心區分有4個室103a~103d。各室103a~103d的前端部設有以洗滌水之噴射力使洗滌噴嘴101旋轉的推進孔104。經泵供給之洗滌水的吐出部105與洗滌噴嘴101的旋轉軸102之間設有圓筒狀的接收筒106。接收筒內106設有浮標107。The structure of the washing nozzle of the conventional dishwasher is as shown in Figs. 11 and 12 (for example, refer to Patent Document 1). Hereinafter, the structure will be described. As shown in the figure, the washing nozzle 101 which sprays the washing water in the washing tub and is free to rotate is divided into four chambers 103a to 103d centering on the rotating shaft 102. The front end portion of each of the chambers 103a to 103d is provided with a thrust hole 104 for rotating the washing nozzle 101 by the jetting force of the washing water. A cylindrical receiving cylinder 106 is provided between the discharge portion 105 of the washing water supplied by the pump and the rotating shaft 102 of the washing nozzle 101. A buoy 107 is provided in the receiving cylinder 106.
浮標107係因從泵吐出之洗滌水而一面旋轉一面上升於接收筒106內，並關閉通往互為對角之室103c、103d的開口部108a。另一方面，洗滌水便從開啟之開口部108b流入室103a、103b。藉此，洗滌噴嘴便一面旋轉一面噴射洗滌水。當停止泵時，浮標107便下降於接收筒內106。當再次驅動泵時，浮標107便因從泵吐出之洗滌水而一面旋轉一面上升於接收筒103內，並關閉通往互為對角之室103a、103b的開口部108b，並且開啟開口部108a。藉此，洗滌水便流入互為對角之室103c、103d。這樣一來，洗滌噴嘴101便反轉，並一面朝反方向旋轉一面噴射洗滌水。The buoy 107 rises in the receiving cylinder 106 while rotating from the washing water discharged from the pump, and closes the opening 108a leading to the mutually diagonal chambers 103c and 103d. On the other hand, the washing water flows into the chambers 103a and 103b from the opened opening portion 108b. Thereby, the washing nozzle ejects the washing water while rotating. When the pump is stopped, the buoy 107 is lowered into the receiving cylinder 106. When the pump is driven again, the buoy 107 rises in the receiving cylinder 103 while rotating by the washing water spouted from the pump, and closes the opening portion 108b leading to the mutually diagonal chambers 103a, 103b, and opens the opening portion 108a. . Thereby, the washing water flows into the chambers 103c and 103d which are diagonal to each other. In this way, the washing nozzle 101 is reversed, and the washing water is sprayed while rotating in the opposite direction.
即，藉由反覆進行泵之驅動與停止，可使浮標107一面旋轉並上下移動於接收筒106內，並可正反轉換洗滌噴嘴101之旋轉方向。That is, by repeatedly driving and stopping the pump, the buoy 107 can be rotated and moved up and down in the receiving cylinder 106, and the rotation direction of the washing nozzle 101 can be reversed.
然而，在習知之餐具清洗機中，在停止泵並切換洗滌水之流路時，浮標107係如第10圖所示，下降於接收筒106內並遠離洗滌噴嘴101。但，由於浮標107設於不與洗滌噴嘴101一起旋轉之接收筒106，因此洗滌噴嘴101亦會於浮標107遠離洗滌噴嘴101時旋轉。因此，當浮標107再次朝著洗滌噴嘴101上升並卡合時，則有再次堵塞前次業已堵塞之流路的可能性。However, in the conventional dishwasher, when the pump is stopped and the flow path of the washing water is switched, the buoy 107 is lowered into the receiving cylinder 106 and away from the washing nozzle 101 as shown in Fig. 10. However, since the buoy 107 is provided in the receiving cylinder 106 that does not rotate with the washing nozzle 101, the washing nozzle 101 also rotates when the buoy 107 is away from the washing nozzle 101. Therefore, when the buoy 107 rises again toward the washing nozzle 101 and is engaged, there is a possibility that the flow path that has been blocked in the previous time is blocked again.
即，由於浮標107與洗滌噴嘴101在浮標107遠離洗滌噴嘴101時各自獨立旋轉，因此浮標107無法依序堵塞流路。結果，洗滌噴嘴101之旋轉方向的轉換便會不規則，便會於洗滌水所接觸之餐具等產生偏向或洗滌不均勻。That is, since the buoy 107 and the washing nozzle 101 are independently rotated when the buoy 107 is away from the washing nozzle 101, the buoy 107 cannot block the flow path in order. As a result, the change in the direction of rotation of the washing nozzle 101 is irregular, and the tableware or the like which is in contact with the washing water may be biased or unevenly washed.

The lower engagement portion 27 has an inclined surface that is at the same angle as the inclined surface of the rotation shaft side engagement portion 28, and is engageable with the rotation shaft side engagement portion 28.
接著針對在前述結構中餐具清洗機之基本動作進行說明。首先，由使用者從餐具清洗機本體1之開口部將餐具等 被洗滌物3安置於餐具箱4，並將被洗滌物3收納至洗滌槽2。接著，在使用者放入預定量的洗滌劑後，便藉由關閉門而將餐具清洗機之本體1的開口部堵塞，並開始運轉。之後，依序進行去除被洗滌物3之汙漬的洗滌步驟、濯洗附著於被洗滌物3之洗滌劑及殘渣的濯洗步驟、及烘乾附著於被洗滌物3之水滴的烘乾步驟。Next, the basic operation of the dishwasher in the above configuration will be described. First, the user places the tableware, etc. from the opening of the dishwasher body 1. The laundry 3 is placed in the cutlery box 4, and the laundry 3 is stored in the washing tub 2. Next, after the user puts in a predetermined amount of detergent, the opening of the body 1 of the dishwasher is closed by closing the door, and the operation is started. Thereafter, a washing step of removing the stain of the laundry 3, a washing step of washing the detergent and the residue adhering to the laundry 3, and a drying step of drying the water droplet adhering to the laundry 3 are sequentially performed.
首先，控制部係使供水閥5運作，以將預定量的洗滌水供給至洗滌槽2，接著利用洗滌泵6加壓洗滌水，並從洗滌噴嘴7噴射洗滌水。此時，設於洗滌槽2內之覆套加熱器等之發熱體11變通有電，以一面加熱洗滌水一面進行洗滌步驟。接著，溫度感測器12便透過洗滌槽2之壁檢測洗滌槽2內之洗滌水的溫度。當溫度感測器12檢測出溫度在預定溫度以上時，控制部便停止對於發熱體11之通電。First, the control unit operates the water supply valve 5 to supply a predetermined amount of washing water to the washing tub 2, and then pressurizes the washing water by the washing pump 6, and sprays the washing water from the washing nozzle 7. At this time, the heating element 11 of the cover heater or the like provided in the washing tub 2 is electrically charged, and the washing step is performed while heating the washing water. Next, the temperature sensor 12 detects the temperature of the washing water in the washing tub 2 through the wall of the washing tub 2. When the temperature sensor 12 detects that the temperature is above a predetermined temperature, the control unit stops energization of the heating element 11.
洗滌水之循環係藉由洗滌泵6之運作而進行。具體而言，藉由洗滌泵6之運作，洗滌水便通過排水過濾器9與殘渣過濾器10，並由設於循環路徑33內之洗滌泵6吸入。接著，洗滌泵6便加壓洗滌水，並將洗滌水供給至設於洗滌槽2內之底部的洗滌噴嘴7。經洗滌泵6供給之洗滌水則從旋轉軸14之軸開口部24流入旋轉軸14內。The circulation of the washing water is carried out by the operation of the washing pump 6. Specifically, by the operation of the washing pump 6, the washing water passes through the drain filter 9 and the residue filter 10, and is sucked by the washing pump 6 provided in the circulation path 33. Next, the washing pump 6 pressurizes the washing water, and supplies the washing water to the washing nozzle 7 provided at the bottom in the washing tub 2. The washing water supplied through the washing pump 6 flows into the rotating shaft 14 from the shaft opening portion 24 of the rotating shaft 14.
閥體21係以閉合部23之下面承受來自流入之洗滌水之較閥體21之自重大的水壓並開始上升。即，閥體21係以閉合部23之下面承受來自流入之洗滌水之較閥體21之自重大的水壓並朝第1及第2洗滌流路入口17、18移動。之後，閥體21便與噴嘴部100卡合。具體而言，由於上面卡合部26卡 合於第2洗滌流路入口18，因此第2洗滌流路入口18與閉合部23一致。又，同時第1洗滌流路入口17與閥體21之開口部22一致。藉此，第2洗滌流路入口18便由閥體21之閉合部23堵塞，洗滌水則從第1洗滌流路入口17流入噴嘴部100內之第1洗滌流路15。流入第1洗滌流路15之洗滌水係從設有多數的第1噴射口19噴射至被洗滌物3。此時，洗滌噴嘴7係因洗滌水之噴射的反作用力朝逆時鐘方向旋轉。又，閥體21係在堵塞第2洗滌流路入口18之情況下與洗滌噴嘴同期旋轉。The valve body 21 receives the self-intense water pressure from the inflowing washing water from the lower surface of the closing portion 23 and starts to rise. In other words, the valve body 21 receives the self-intense water pressure from the inflowing washing water to the lower surface of the closing portion 23 and moves toward the first and second washing flow path inlets 17, 18. Thereafter, the valve body 21 is engaged with the nozzle portion 100. Specifically, since the upper engaging portion 26 is stuck Since it is joined to the second washing channel inlet 18, the second washing channel inlet 18 coincides with the closing portion 23. Further, at the same time, the first washing channel inlet 17 coincides with the opening 22 of the valve body 21. Thereby, the second washing flow path inlet 18 is closed by the closing portion 23 of the valve body 21, and the washing water flows into the first washing flow path 15 in the nozzle unit 100 from the first washing flow path inlet 17. The washing water that has flowed into the first washing flow path 15 is ejected from the first injection port 19 that is provided in a large amount to the object 3 to be washed. At this time, the washing nozzle 7 is rotated in the counterclockwise direction by the reaction force of the jet of washing water. Further, the valve body 21 rotates in synchronization with the washing nozzle when the second washing flow path inlet 18 is closed.
當使第1噴射口19噴射預定時間的洗滌水時，控制部係使洗滌泵6停止預定時間。結果，閥體21之閉合部23未再承受到較自重大之水壓，因此開始與第1洗滌流路入口17分離並下降。When the first injection port 19 is caused to inject the washing water for a predetermined time, the control unit stops the washing pump 6 for a predetermined time. As a result, the closed portion 23 of the valve body 21 is no longer subjected to a relatively large water pressure, so that it starts to separate from the first washing flow path inlet 17 and descends.
此時，業經加壓之洗滌水便因洗滌泵6之停止而無法供給至洗滌噴嘴7。又，此時，由於洗滌槽2內之水位較洗滌噴嘴7之噴嘴部100低，因此未噴射於洗滌噴嘴7內而留下的洗滌水便會朝洗滌泵6逆流，即，開始下降。再者，由於閥體21以堵塞第1或第2洗滌流路入口17、18之狀態位於較洗滌槽2內之水位高的位置，因此閥體21便以上面承受逆流之洗滌水的水壓。藉此，便會加速閥體21之下降，因此可縮短切替閥體21所需的時間。之後，閥體21便因下面卡合部27與旋轉軸14之旋轉軸側卡合部28卡合而停止下降。閥體21係在與旋轉軸側卡合部28卡合時與洗滌噴嘴7同期旋轉者。At this time, the pressurized washing water cannot be supplied to the washing nozzle 7 due to the stop of the washing pump 6. Further, at this time, since the water level in the washing tub 2 is lower than the nozzle portion 100 of the washing nozzle 7, the washing water remaining in the washing nozzle 7 does not flow back toward the washing pump 6, that is, starts to descend. Further, since the valve body 21 is located at a position higher than the water level in the washing tank 2 in a state in which the first or second washing flow path inlets 17, 18 are blocked, the valve body 21 receives the water pressure of the washing water which is countercurrent to the upper side. . Thereby, the lowering of the valve body 21 is accelerated, so that the time required to cut the valve body 21 can be shortened. Thereafter, the valve body 21 is stopped by the engagement of the lower engagement portion 27 with the rotation shaft side engagement portion 28 of the rotary shaft 14. The valve body 21 is rotated in synchronization with the washing nozzle 7 when it is engaged with the rotating shaft side engaging portion 28.
接著，開始驅動洗滌泵6，閥體21便以閉合部23之下面承受來自流入之洗滌水之較閥體21之自重大的水壓並再次朝第1或第2洗滌流路入口17、18移動。之後，閥體21便再次與噴嘴部100卡合。具體而言，由於上面卡合部26與不同於前述之第1洗滌流路入口17卡合，因此第1洗滌流路入口17與閉合部23一致。又，同時第2洗滌流路入口18與閥體21之開口部22一致。藉此，第1洗滌流路入口17便因閥體21之閉合部23而堵塞，洗滌水則從第2洗滌流路入口18流入噴嘴部100內之第2洗滌流路16。流入第2洗滌流路16之洗滌水便從設有多數的第2噴射口20噴射至被洗滌物3。又，閥體21係在堵塞第1洗滌流路入口17的情況下與洗滌噴嘴7同期旋轉者。此時，洗滌噴嘴7係因洗滌水之噴射的反作用力朝順時鐘方向旋轉。即，藉由以閥體21切換流路，洗滌噴嘴7之旋轉方向便會朝反方向旋轉。這樣一來，便可利用閥體21於預定時間反覆進行第1及第2洗滌流路入口17、18之切換動作。Then, the washing pump 6 is started to be driven, and the valve body 21 receives the water pressure from the inflowing washing water to the valve body 21 from the lower side of the closing portion 23 and again toward the first or second washing flow path inlets 17, 18 mobile. Thereafter, the valve body 21 is again engaged with the nozzle portion 100. Specifically, since the upper engaging portion 26 is engaged with the first washing channel inlet 17 different from the above, the first washing channel inlet 17 and the closing portion 23 coincide with each other. Further, at the same time, the second washing channel inlet 18 coincides with the opening 22 of the valve body 21. As a result, the first washing channel inlet 17 is closed by the closing portion 23 of the valve body 21, and the washing water flows into the second washing channel 16 in the nozzle portion 100 from the second washing channel inlet 18. The washing water that has flowed into the second washing flow path 16 is ejected from the second injection port 20 that is provided in a large amount to the object 3 to be washed. Further, the valve body 21 is rotated in synchronization with the washing nozzle 7 when the first washing flow path inlet 17 is closed. At this time, the washing nozzle 7 is rotated in the clockwise direction by the reaction force of the ejection of the washing water. That is, by switching the flow path by the valve body 21, the rotation direction of the washing nozzle 7 is rotated in the reverse direction. In this way, the switching operation of the first and second washing flow path inlets 17, 18 can be repeated by the valve body 21 for a predetermined time.
如前所述，閥體21係在堵塞第1洗滌流路入口17及第2洗滌流路入口18之任一者時，以及卡合旋轉軸側卡合部28時，與洗滌噴嘴7同期旋轉者。除此之外，即，當閥體21在旋轉軸14內進退運作於流動方向(在本實施型態中為上下方向)時則與洗滌噴嘴7完全不同期。閥體21係因進退運作而旋動大約90度者，其詳細狀況留至後述。即，當閥體21於旋轉軸14內進退運作於流動方向時，係加上洗滌噴嘴7之旋轉角度，以可切換洗滌流路入口之程度(約90度)旋轉。其 中，由於閥體21係在進退運作時與洗滌噴嘴各自獨立旋轉，因此會因慣性而產生旋轉。然而，藉由縮短旋轉軸側卡合部28與洗滌流路入口17、18之距離，可非常大幅地縮短閥體21之進退運作所需的時間，並可抑制洗滌噴嘴7與閥體21之旋轉錯移，故可抑制因慣性而產生旋轉。因此，閥體21則因進退運作而僅對洗滌噴嘴7旋動約90度，而可確實地實現洗滌流路之切換。As described above, when the valve body 21 blocks one of the first washing flow path inlet 17 and the second washing flow path inlet 18, and when the rotating shaft side engaging portion 28 is engaged, the valve body 21 rotates synchronously with the washing nozzle 7. By. In addition, when the valve body 21 moves forward and backward in the rotating shaft 14 in the flow direction (up and down direction in the present embodiment), it is completely different from the washing nozzle 7. The valve body 21 is rotated by about 90 degrees due to the advancement and retreat operation, and the details thereof will be described later. That is, when the valve body 21 moves forward and backward in the rotating shaft 14 in the flow direction, the rotation angle of the washing nozzle 7 is added to rotate the degree of the washing flow path inlet (about 90 degrees). its In the middle, since the valve body 21 rotates independently of the washing nozzles during the forward and backward operation, the rotation occurs due to inertia. However, by shortening the distance between the rotating shaft side engaging portion 28 and the washing flow path inlets 17, 18, the time required for the forward and backward operation of the valve body 21 can be greatly shortened, and the washing nozzle 7 and the valve body 21 can be suppressed. Since the rotation is shifted, rotation due to inertia can be suppressed. Therefore, the valve body 21 is rotated only about 90 degrees to the washing nozzle 7 by the advancing and retracting operation, and the switching of the washing flow path can be surely achieved.
在此，針對本實施型態之閥體21之結構、切換動作與功用進行詳細地說明。藉由使洗滌泵6運轉，閥體21便以閉合部23承受自旋轉軸14之軸開口部24流入之洗滌水的水壓並開始上升。之後，第7圖所示之上面卡合部26之傾斜部分便滑動於設以隔開第2圖所示之噴嘴部100內之流路的十字狀分隔壁34，閥體21則一面旋轉一面上升於略垂直的方向。之後，如第5圖所示，上面卡合部26便與第2洗滌流路入口18卡合，而閥體21之閉合部23便與第2洗滌流路入口18相對且堵塞第2洗滌流路入口18。同時，開口部22則與第1洗滌流路入口17相對並開啟第1洗滌流路入口17。此時，上面卡合部26呈朝旋轉方向傾斜之形狀，而閥體21便一面滑動於分隔壁34，一面與第2洗滌流路入口18卡合，並因上面卡合部26之傾斜而僅旋動第1預定角度(例如45度)。Here, the configuration, switching operation, and function of the valve body 21 of the present embodiment will be described in detail. When the washing pump 6 is operated, the valve body 21 receives the water pressure of the washing water flowing from the shaft opening portion 24 of the rotating shaft 14 by the closing portion 23 and starts to rise. Thereafter, the inclined portion of the upper engaging portion 26 shown in Fig. 7 is slid to the cross-shaped partition wall 34 which is provided to partition the flow path in the nozzle portion 100 shown in Fig. 2, and the valve body 21 is rotated while rotating. Rise in a slightly vertical direction. Thereafter, as shown in Fig. 5, the upper engaging portion 26 is engaged with the second washing flow path inlet 18, and the closing portion 23 of the valve body 21 is opposed to the second washing flow path inlet 18 and blocks the second washing flow. Road entrance 18. At the same time, the opening 22 faces the first washing channel inlet 17 and opens the first washing channel inlet 17. At this time, the upper engaging portion 26 has a shape inclined in the rotational direction, and the valve body 21 slides on the partition wall 34 to engage with the second washing flow path inlet 18, and the upper engaging portion 26 is inclined. Only the first predetermined angle (for example, 45 degrees) is rotated.
之後，洗滌泵6持續以預定時間運轉，而第1洗滌流路入口17則固定於開口位置，且與第1洗滌流路入口17連通之第1洗滌流路供15給有洗滌水。Thereafter, the washing pump 6 continues to operate for a predetermined period of time, and the first washing channel inlet 17 is fixed to the opening position, and the first washing channel that is in communication with the first washing channel inlet 17 is supplied with the washing water.
接著，當洗滌泵6一時停止時，閥體21之閉合部23便未 再承受到較自重大之水壓，因此開始與第1洗滌流路入口17分離並因自重而下降。此時，如第4圖所示，下面卡合部27便一面沿著設於旋轉軸14之旋轉軸側卡合部28的傾斜面滑動一面卡合，而閥體21則僅以第2預定角度(例如45度)旋動。之後，閥體21便因下面卡合部27與旋轉軸側卡合部28之階梯部28b抵接而停止。Then, when the washing pump 6 is stopped for a while, the closing portion 23 of the valve body 21 is not Since it is subjected to a relatively large water pressure, it starts to separate from the first washing flow path inlet 17 and is lowered by its own weight. At this time, as shown in Fig. 4, the lower engaging portion 27 is engaged with the inclined surface provided on the rotating shaft side engaging portion 28 of the rotating shaft 14, and the valve body 21 is only predetermined by the second. The angle (for example, 45 degrees) is rotated. Thereafter, the valve body 21 is stopped by the lower engaging portion 27 abutting against the step portion 28b of the rotating shaft side engaging portion 28.
之後，藉由再次使洗滌泵6運作，閥體21便朝上方移動並滑動於分隔壁34，並且僅以第1角度旋動而與第1洗滌流路入口17卡合。Thereafter, by operating the washing pump 6 again, the valve body 21 moves upward and slides on the partition wall 34, and is rotated only at the first angle to engage with the first washing flow path inlet 17.
即，閥體21係藉由一次進退移動而旋動第1角度與第2角度的合計角度，即，約90度者。另一方面，第1洗滌流路入口17及第2洗滌流路入口18皆呈中心角為第1角度與第2角度之合計角度(90度)的扇狀。即，閥體21係藉由1次進退運作，即，上下往復運動而旋動第1角度與第2角度之合計角度(約90度)，並僅旋轉可切換第1及第2洗滌流路入口17、18之角度。之後，閥體21藉由進行4次往復運動，而旋動360度並回到原本的位置。如前所述，藉由間歇地驅動洗滌泵6，閥體便進行進退運動，並與噴嘴部100卡合，因此可依序堵塞第1及第2洗滌流路入口，並可依序切換流動有洗滌水之洗滌流路入口17、18。因此，不需使用馬達等致動器切換閥體21，故，旋轉軸14之流路內不會有閥體21以外妨礙洗滌水流動的東西，更可使洗滌噴嘴7與閥體21一起旋轉。又，閥體21之上面卡合部26係與第1及第2洗滌流路入口卡合者，而下面卡合部27係與旋轉軸14之旋轉軸側卡合 部28卡合者。因此，閥體21係在洗滌泵6驅動時與上面卡合部26卡合並旋動，並且在洗滌泵6停止時與下面卡合部27卡合並旋動者，故可使閥體21、洗滌噴嘴7之流路入口及旋轉軸14之相對位置的關係經常保持於一致。這樣一來，由於閥體21與洗滌噴嘴7連動並旋轉，因此可確實地利用閥體21進行流路之切替，並可一面實現節水一面充分地洗滌餐具。又，如第10圖所示，藉由以預定角度(例如x度)錯開分隔壁34與階梯部28b，而可更確實地利用閥體21實行流路的切替。That is, the valve body 21 rotates the total angle of the first angle and the second angle by one advance and retreat movement, that is, about 90 degrees. On the other hand, each of the first washing flow path inlet 17 and the second washing flow path inlet 18 has a fan shape in which the central angle is a total angle (90 degrees) between the first angle and the second angle. In other words, the valve body 21 is operated by one advance and retreat, that is, the upper and lower reciprocating motions are rotated to rotate the total angle of the first angle and the second angle (about 90 degrees), and only the first and second washing flow paths can be switched by rotation. The angle of the entrances 17, 18. Thereafter, the valve body 21 is rotated 360 degrees and returned to the original position by performing four reciprocating motions. As described above, by intermittently driving the washing pump 6, the valve body moves forward and backward and is engaged with the nozzle portion 100, so that the first and second washing flow path inlets can be sequentially blocked, and the flow can be sequentially switched. There are washing water path inlets 17, 18 for washing water. Therefore, it is not necessary to use the actuator such as a motor to switch the valve body 21, so that the flow path of the rotary shaft 14 does not interfere with the flow of the washing water other than the valve body 21, and the washing nozzle 7 can be rotated together with the valve body 21. . Further, the upper engaging portion 26 of the valve body 21 is engaged with the first and second washing flow path inlets, and the lower engaging portion 27 is engaged with the rotating shaft side of the rotating shaft 14. Part 28 is the fitter. Therefore, the valve body 21 is engaged with the upper engaging portion 26 when the washing pump 6 is driven, and is rotated and engaged with the lower engaging portion 27 when the washing pump 6 is stopped, so that the valve body 21 can be washed. The relationship between the flow path inlet of the nozzle 7 and the relative position of the rotary shaft 14 is often kept uniform. In this way, since the valve body 21 is rotated in conjunction with the washing nozzle 7, the valve body 21 can be reliably used to cut the flow path, and the tableware can be sufficiently washed while realizing water saving. Further, as shown in Fig. 10, by disposing the partition wall 34 and the step portion 28b at a predetermined angle (for example, x degrees), it is possible to more reliably perform the switching of the flow path by the valve body 21.
又，洗滌水係在從噴嘴部100之噴射口19、20噴射並洗滌被洗滌物3之後，再回到排水口8者。此時，從被洗滌物3脫落之殘渣等係與洗滌水一起流入殘渣過濾器10。而無法通過殘渣過濾器10且大於多數設於殘渣過濾器10之孔的殘渣則由殘渣過濾器10所補集。Further, the washing water is sprayed from the injection ports 19 and 20 of the nozzle unit 100 and washed to the laundry 3, and then returned to the drain port 8. At this time, the residue or the like which has fallen off from the laundry 3 flows into the residue filter 10 together with the washing water. The residue that cannot pass through the residue filter 10 and is larger than the majority of the pores provided in the residue filter 10 is supplemented by the residue filter 10.
當預定時間之洗滌步驟結束後，便將含有汙漬之洗滌水排出至餐具清洗機本體1外，並重新供給洗滌水。之後，使洗滌泵6運轉，並從洗滌噴嘴7再次噴射洗滌水，以濯洗附著有洗滌劑或殘渣等之被洗滌物3。在進行預定時間之運轉後，便反覆進行排出洗滌水、再次供給洗滌水等動作。前述濯洗步驟係經控制部控制而連續進行三次左右。最後，將洗滌水排出至餐具清洗機本體1外，以結束濯洗步驟。接著，進行烘乾步驟，並在進行預定時間之烘乾後結束運轉。After the washing step of the predetermined time is over, the washing water containing the stain is discharged to the outside of the dishwasher body 1, and the washing water is re-supplied. Thereafter, the washing pump 6 is operated, and the washing water is sprayed again from the washing nozzle 7 to wash the laundry 3 to which the detergent or the residue adheres. After the operation for a predetermined period of time, the operation of discharging the washing water and supplying the washing water again is repeated. The rinsing step is continuously performed three times or so under the control of the control unit. Finally, the washing water is discharged to the outside of the dishwasher body 1 to end the washing step. Next, the drying step is performed, and the operation is completed after drying for a predetermined time.
根據本發明之結構，由於連通於洗滌噴嘴7之噴嘴部 100之各洗滌流路的洗滌流路入口與閥體21之相對位置的關係經常固定於預定位置，因此可確實且穩定地進行流路的切換。又，由於可從多數噴射口將洗滌水噴射於被洗滌物3，因此可大範圍、高密度且均等地將洗滌水噴射於洗滌槽2內的全部被洗滌物3，並可提升洗滌效能。又，即使洗滌泵之能力相同，亦可達到提升洗滌效能之目的。According to the structure of the present invention, the nozzle portion that communicates with the washing nozzle 7 The relationship between the washing flow path inlet of each of the washing passages 100 and the relative position of the valve body 21 is often fixed at a predetermined position, so that the flow path can be switched reliably and stably. Further, since the washing water can be sprayed from the plurality of injection ports to the laundry 3, the washing water can be sprayed onto the entire laundry 3 in the washing tub 2 in a wide range, high density, and uniformly, and the washing performance can be improved. Moreover, even if the capacity of the washing pump is the same, the purpose of improving the washing performance can be achieved.
又，閥體21對於流動方向之移動、閥體21與第1及第2洗滌流路入口17、18之嵌合因支撐軸29與中空圓筒部30而可順利進行。再者，由於支撐軸29設於從閥體21之上方，即，洗滌水之流動方向看來之閥體21的下流側，因此洗滌水會流過閥體21之開口部22，故不會因支撐軸29而妨礙流動。因此，藉由設於洗滌水所流動之流路的切換結構可減少流動阻力，並可確實地切換流路，因此可達到提升洗滌效能之目的。Further, the movement of the valve body 21 in the flow direction and the fitting of the valve body 21 and the first and second washing flow path inlets 17 and 18 can be smoothly performed by the support shaft 29 and the hollow cylindrical portion 30. Further, since the support shaft 29 is provided above the valve body 21, that is, the downstream side of the valve body 21 in the flow direction of the washing water, the washing water flows through the opening portion 22 of the valve body 21, so that it does not The flow is hindered by the support shaft 29. Therefore, by the switching structure provided in the flow path through which the washing water flows, the flow resistance can be reduced, and the flow path can be surely switched, so that the purpose of improving the washing performance can be achieved.
又，閥體21之中空圓筒部30於含有洗滌流路入口側端面之側壁設有側壁開口部31，故可使進入閥體21之中空圓筒部30與支撐軸29之卡合間隙的異物從側壁開口部31流出。藉此，可防止閥體21因異物而產生進退運作不佳，並可確實地切換流路，因此可達到提升洗滌效能之目的。Further, since the hollow cylindrical portion 30 of the valve body 21 is provided with the side wall opening portion 31 on the side wall including the end surface of the inlet side of the washing flow path, the gap between the hollow cylindrical portion 30 of the valve body 21 and the support shaft 29 can be made. The foreign matter flows out from the side wall opening portion 31. Thereby, it is possible to prevent the valve body 21 from being inferior in advance and retreat due to foreign matter, and to reliably switch the flow path, thereby achieving the purpose of improving the washing performance.
又，在閥體21之中空圓筒部30中，旋轉軸14之軸開口部24側，即，從洗滌水之流動方向看來之對於閥體21之上流側之流動呈略垂直的端面係由底壁30a所堵塞，且於側壁設有排水孔32。因此，從旋轉軸14之軸開口部24流入之洗滌水與洗滌水中之異物不會直接進入中空圓筒部30，故可 防止異物進入。Further, in the hollow cylindrical portion 30 of the valve body 21, the shaft opening portion 24 side of the rotary shaft 14 is a side surface which is slightly perpendicular to the flow side of the valve body 21 as viewed from the flow direction of the washing water. It is blocked by the bottom wall 30a, and a drain hole 32 is provided in the side wall. Therefore, the foreign matter flowing into the washing water and the washing water flowing from the shaft opening portion 24 of the rotating shaft 14 does not directly enter the hollow cylindrical portion 30, so Prevent foreign matter from entering.
又，當洗滌泵6停止時，從中空圓筒部30上方進入之洗滌水與異物係通過排水孔32從中空圓筒部30內流出。因此，其具有耐用的結構並可確實地切換流路，故可達到提升洗滌效能之目的。Further, when the washing pump 6 is stopped, the washing water and the foreign matter entering from above the hollow cylindrical portion 30 flow out from the hollow cylindrical portion 30 through the drain hole 32. Therefore, it has a durable structure and can reliably switch the flow path, so that the purpose of improving the washing performance can be achieved.
又，閥體21與旋轉軸14之內壁間設有間隙D。藉由將該間隙D之幅度設定在排水過濾器9之開口部之幅度以上，而可防止從被洗滌物3洗出之殘渣等通過排水過濾器9並卡於閥體21與旋轉軸14之內壁間，而妨礙閥體21之運作。藉此，不會產生洗滌不佳，並可確實地利用閥體21進行流路切換。Further, a gap D is provided between the valve body 21 and the inner wall of the rotary shaft 14. By setting the width of the gap D to be larger than the width of the opening of the drain filter 9, it is possible to prevent the residue or the like washed out from the laundry 3 from passing through the drain filter 9 and being caught by the valve body 21 and the rotary shaft 14. Between the inner walls, the operation of the valve body 21 is hindered. Thereby, the washing is not performed poorly, and the flow path switching can be reliably performed by the valve body 21.
又，藉由將旋轉軸14之軸開口部24之直徑設定在閥體21之直徑(閉合部23之直徑)以下，而可將與閥體21之下面卡合部27卡合之旋轉軸側卡合部28設置於直徑較旋轉軸14之軸開口部24之直徑大的位置。藉此，可在不妨礙洗滌水之流動下使閥體21順利地旋動，並可實現洗滌水之流動阻力較少的結構。Further, by setting the diameter of the shaft opening portion 24 of the rotary shaft 14 to be equal to or smaller than the diameter of the valve body 21 (the diameter of the closing portion 23), the rotation shaft side that engages with the lower surface engaging portion 27 of the valve body 21 can be engaged. The engaging portion 28 is provided at a position having a diameter larger than the diameter of the shaft opening portion 24 of the rotating shaft 14. Thereby, the valve body 21 can be smoothly rotated without hindering the flow of the washing water, and the structure in which the flow resistance of the washing water is small can be achieved.
又，藉由於各流路15、16中將噴射口19、20配置成分別與旋轉中心之距離不同，雖然噴射口19、20會因洗滌噴嘴7之旋轉而通過以旋轉軸14為中心之圓的軌跡，但亦會於洗滌噴嘴7之外徑內增加噴射口19、20之軌跡。因此，可高密度且均等地將洗滌水噴射於被洗滌物3，故可達到提升洗滌效能之目的。Further, since the injection ports 19 and 20 are arranged to have different distances from the rotation center in each of the flow paths 15 and 16, the injection ports 19 and 20 pass through the circle centered on the rotation axis 14 due to the rotation of the washing nozzle 7. The trajectory, but also increases the trajectory of the injection ports 19, 20 within the outer diameter of the washing nozzle 7. Therefore, the washing water can be sprayed onto the object 3 with high density and uniformity, so that the purpose of improving the washing performance can be achieved.
又，藉由將洗滌噴嘴7構造成因供給有洗滌水之流路而旋轉方向不同的結構，則可藉由改變洗滌噴嘴7之旋轉方向 改變來自噴射口19、20之洗滌水的噴射角度。藉此，可從多數角度噴射洗滌水於被洗滌物3，而可如更確實地洗滌被洗滌物3之表裡兩面等有效率地進行洗滌並可提升洗滌效能。Further, by configuring the washing nozzle 7 to have a structure in which the direction of rotation is different due to the flow path to which the washing water is supplied, the rotation direction of the washing nozzle 7 can be changed. The spray angle of the wash water from the injection ports 19, 20 is changed. Thereby, the washing water can be sprayed from the laundry to the laundry 3 at a plurality of angles, and the washing can be efficiently performed by washing the both sides of the surface of the laundry 3 more reliably and the cleaning performance can be improved.
即，由於洗滌噴嘴7係利用來自噴射口19、20之噴射的反作用力旋轉，因此噴射口19、20的角度係設於洗滌噴嘴7之旋轉方向與相反方向全體。當對於碗類或深度較深之器皿類時，若不朝傾斜方向噴射則難使洗滌水進入其內側而無法洗滌。又，由於洗滌噴嘴7構造成因噴射之反作用力旋轉之結構，且合計從正上方傾斜之噴射的旋轉力為旋轉推進力，因此對於旋轉，後退方向之噴射較多。故，若僅朝一方向旋轉，傾斜之噴射則會依情況產生強弱，而產生洗滌力不均勻。That is, since the washing nozzle 7 is rotated by the reaction force from the injection of the injection ports 19, 20, the angles of the injection ports 19, 20 are provided in the entire rotation direction of the washing nozzle 7 and the opposite direction. When it is used for bowls or vessels of deeper depth, it is difficult to wash the water into the inside without washing in the oblique direction. Further, since the washing nozzle 7 is configured to rotate by the reaction force of the jet, and the total rotational force of the jet that is inclined from the upper side is the rotational propulsive force, the jetting in the reverse direction is large for the rotation. Therefore, if the rotation is only performed in one direction, the oblique injection will be strong and weak depending on the situation, and the washing power will be uneven.
由於將洗滌噴嘴7切換於正反旋轉方向可使強弱關係成相反狀態，因此在正向旋轉時，可強化滲透性不佳之部位的滲透性，並且藉由反覆進行前述動作，可消除洗滌力之不均勻，並可均等地洗滌安置於洗滌槽2內之洗滌物3的整體。Since the washing nozzle 7 is switched in the forward and reverse rotation directions, the relationship between the strength and the weakness can be reversed. Therefore, in the forward rotation, the permeability of the portion having poor permeability can be enhanced, and the washing action can be eliminated by repeating the above-described actions. It is uneven, and the whole of the laundry 3 placed in the washing tub 2 can be uniformly washed.
藉由噴射口19、20之噴射角度、方向等之結構不同，可更大範圍且有效率地進行洗滌。By the difference in the structure of the injection angles, directions, and the like of the injection ports 19, 20, the washing can be performed in a wider range and efficiently.
又，在以洗滌劑與熱去除汙漬之洗滌步驟與濯洗洗滌劑與汙漬之濯洗步驟中，由於以閥體21切換各流路15、16之間隔不同，而可減少切換至噴射時間較長之洗滌步驟時的次數，因此可減少切換時時間的損失，並可有效率地進 行洗滌。Further, in the washing step of washing the stain with detergent and heat, and the washing step of washing the detergent and the stain, since the interval between the respective flow paths 15 and 16 is switched by the valve body 21, the switching to the injection time can be reduced. The number of times during the long washing step, thus reducing the loss of time during switching and allowing efficient entry Line washing.
又，由於閥體21可對於各流路15、16之入口17、18自由進退，且閥體21構造成與A面分離之結構，因此可在不卡入混在洗滌水之異物的情況下進行旋轉驅動。在本實施行態中，係使閥體21對應洗滌泵6之開始與停止而進退移動，以切換對於洗滌噴嘴7之多數流路15、16之洗滌水的供給，但亦可使洗滌泵6之旋轉數高速與低速地變化，以使閥體21進退移動。Further, since the valve body 21 can freely advance and retreat to the inlets 17, 18 of the respective flow paths 15, 16, and the valve body 21 is configured to be separated from the A surface, it can be carried out without getting stuck in foreign matter mixed in the washing water. Rotate the drive. In the present embodiment, the valve body 21 is moved forward and backward in response to the start and stop of the washing pump 6, so as to switch the supply of the washing water to the majority of the flow paths 15, 16 of the washing nozzle 7, but the washing pump 6 can also be The number of rotations changes at a high speed and at a low speed to move the valve body 21 forward and backward.
又，藉由將閥體21與面A分離之距離設定在排水過濾器9與殘渣過濾器10之間隙以上，而可將大小在可通過排水過濾器9與殘渣過濾器10並流入閥體21之異物以上的間隙形成於面A與閥體21之間，因此可在洗滌泵6停止時去除夾於其中之異物，故可提供可信度高的切換裝置。Further, by setting the distance separating the valve body 21 from the surface A to be larger than the gap between the drain filter 9 and the residue filter 10, the size can pass through the drain filter 9 and the residue filter 10 and flow into the valve body 21 The gap above the foreign matter is formed between the surface A and the valve body 21, so that the foreign matter sandwiched therein can be removed when the washing pump 6 is stopped, so that a highly reliable switching device can be provided.
又，在本實施型態中，係藉由設於閥體21之卡合部與設於噴嘴部之各流路入口卡合以進行流路的切替，但本發明並不限於前述結構。例如，亦可藉由設於閥體21之卡合部與設於噴嘴之卡合部互相卡合而進行流路之切替。Further, in the present embodiment, the engagement between the engagement portion provided in the valve body 21 and the flow path inlet provided in the nozzle portion is performed, but the present invention is not limited to the above configuration. For example, the flow path may be replaced by the engagement portion provided between the valve body 21 and the engagement portion provided at the nozzle.
如以上所述，本發明之餐具清洗機可確實地以閥體切換流路，並可一面實現節水一面消除餐具之洗滌不均勻並提高洗滌效果，故亦可適用於餐具以外的洗滌機。As described above, the dishwasher of the present invention can reliably switch the flow path by the valve body, and can eliminate the uneven washing of the tableware and improve the washing effect while realizing water saving, and therefore can be applied to a washing machine other than the tableware.
