與第6圖中的習知洗衣機之元件相似的元件以類似標號表 〇 多一實施例 如第1圖所示，控制器⑻空制馬達6、水供應閱9、排水 閥10等之操作，以控制一個或數個洗衣循環。在各循環中， 潤洗以及/或脫水過程接續地或選擇性地控制。控制哭Μ亦 藉由使用包含清潔劑的水槽洗濯液執行水槽洗濯過程，以 10及其後的水槽潤洗過矛呈，以清潔洗衣槽3，可轉動地配置在 其底部上的脈動器2以及外槽1之内表面。 水槽洗濯過程藉由供應液體而執行，其中具有某一濃 度的水槽洗濯液備置於洗衣槽3及外槽4 ;執行浸泡= 程’在該過程中間些地前後轉動脈動器2;然後執行排水過 15程’以自洗衣槽3中排出洗濯液。 在浸泡過程中，水位設定成水位p卜其最好高於在衣 物洗濯循環中可達成的一最高水位；脈動器2的前後轉動以 及轉動停止交麵執行。此外，在浸泡後，執㈣動過程， 其中在洗衣槽3中的洗濯液以脈動器2攪動。 20以下將配合第1及2圖說明洗衣機之操作。在步驟射 按下-開始開關（未顯示），即開始水槽洗濯過程的水槽洗灌 液供應過程。在步驟21中’藉由水供應閥9及水位偵測韻 水供應至洗衣槽3達到預定之ρι水位，該水位高於在洗衣循 環中最高的水位關閉排水閥9。在步驟22中，加入清 9 1243866 潔劑。在步驟23中，馬達6轉動脈動器2以執行一段預定時 間的前後轉動，以溶解清_，並備置具有均勻清潔劑濃 度的水槽洗濯液。 接下來，進入浸泡過程，其同時配合間些地前後轉動 5脈動為2 ’馬達6使得脈動器2在步驟μ中藉由控制器18之開 /關控制執仃W後轉動。藉由脈動器2的前後轉動，在洗衣 槽3中的水槽洗濯液之攪動力量增加，且當脈動器2打開 時，在洗衣槽3内部的液面之中間部份下降，而其外部，即 在洗衣槽3及外槽1之間的液面上升。 ίο 因此在洗衣槽3及外槽1之間的液面升至預定水位ρι 上，使得清潔劑可達到洗衣槽3之外壁及外槽丨之内壁的較 咼水位。反之，在關閉狀態下，洗衣槽3中的液面回升，在 洗衣槽3及外槽丨之間的液面下降。 其後，在步驟25中，執行浸泡一段預定時間，在其間 脈動杰2不作前後轉動，以允許水槽洗濯液足夠地作動在異 物上。在步驟26中，重覆步驟24及25之操作預定次數，使 侍β >糸劑可有效地達到異物，且由脈動器2之前後轉動產生 的水流可移除異物。 20 y接下來’在步驟27中的攪動過程中，藉由脈動器2之前 1轉動’在洗濯及脫水槽3中的水槽洗濯液自泵室13經由水 4 通道14送至棉球過濾器15,因而在水槽洗濯液中的異 勿收集於棉球過濾器15中。同時，沉積在脈動器2、泵室13、 循％通道14等之後側的異物亦可被移除，並收集在棉球 過癔器15中。 10 1243866 接下來’進入排水過程，排水閥10在步驟28中操作， 以自洗衣槽3排出水槽洗濯液，然後進入步驟四中的潤洗過 程。 以此方式，水流可由脈動器2的間隙前後轉動造成，使 5得較多的形成在洗衣槽3之外壁及外槽1之内壁上之異物被 移除；且藉由自動化、笨重之步驟可以自動方式執行，而 形成在洗衣機中的異物可被移除。 此外，在浸泡過程中，預設之水位設定成較洗衣循環 中的最高水位高，且水槽洗濯液被脈動器2的交替前後轉動 10及停止轉動而攪動；此外，在洗衣槽3内的液面高度之中間 部份在洗衣槽3及外槽1之間的液面高度上升時下降，因 此’水槽洗濯液可達到並清除高於洗衣循環最高水位之上 形成在洗衣槽3之外壁及外槽1之内壁上的異物。 此外，在浸泡後，藉由以脈動器2攪動洗衣槽3中的水 15 槽洗濯液之授動過程，因浸泡過程而移除的異物可收集在 棉球過濾、器15中。 在此實施例中，在水槽洗濯液供應過程及浸泡過程中 水位維持相同。然而，在水槽洗濯液供應過程中的水位可 设疋成，譬如，洗衣循環之最高水位，且水可在浸泡過程 2〇後供應較多，至較最南水位為高的水位。在此狀況下，清 >糸劑可在水槽洗濯液供應過程中較快地溶化。 JL二實施例 如第3圖所示，控制器29控制馬達6、水供應閥9、排水 閥10等之操作，以接續地或選擇地控制衣物洗濯、潤洗及 1243866 脫水過程，並使用其中包含清潔劑的水槽洗濯液執行水槽 洗濯過程，以及水槽潤洗過程，以清潔洗衣槽3及裝載洗衣 槽3於其中之外槽1的内表面。潤洗過程至少執行一次，接 續的過程為：水槽轉動潤洗過程，其中水供應閥9及排水閥 5 10同時在洗衣槽3以低速轉動時打開；第一攪動過程，其中 脈動器2以較排水閥1〇關閉時浸泡過程中少量的水轉動；第 二攪動過程，其中脈動器2以與在浸泡過程中等量的水轉 動；以及排水過程在排水閥1〇打開時執行。 此外’在潤洗過程之排水過程前最好執行水供應潤洗 10過程。其他元件與前述第一較佳實施例相同；因此，該元 件以相同標號表示，且省略其說明。 現在配合第3、4圖說明上述洗衣機之操作。在完成水 槽洗濯過程後，進入如下之水槽潤洗過程：首先，在步驟 31中，執行水槽轉動潤洗過程，其中水供應閥9及排水閥1〇 15打開或在洗衣槽3以低速轉動的同時打開或操作，使得水槽 潤洗過程結束維持在，譬如，脈動器2上，洗衣槽3的外壁 之底部以及外槽1的内壁之底部上的異物隨著排水一起排 出。此外’可執行水供應及排水過程以取代執行水槽轉動 潤洗過程，其中在藉由操作水供應閥9及排水閥1〇幾乎同時 20供水及排水時，洗衣槽3不轉動。 接下來，水藉由水供應閥9及水位偵測器η在步驟32中 供應至低水位P2，此時，排水閥1〇是關閉的。接下來，在 步驟33中執行第一攪動洗濯過程，其中馬達6被驅動以使脈 動器2前後轉動-段預定的時間，造成維持在洗衣槽3及外 12 1243866 槽1之間的異物捕捉在水槽洗濯液中。此時，由於脈動器2 以小量水前後轉動，可形成有力量的水流’使移除之異物 打碎成小片。 接下來，在步驟34中，水由水供應閥9及水位侧器^ 5供應，而排水閥10關閉，直到高達水槽洗濯過程中之浸泡 過程的水位P1，該水位高於第i動潤洗過㈣的水位 P2 ;在步驟35中，執行第二撲動潤洗過程，其中脈動器2 的前後轉動以馬達6執行—段時間’潤洗掉留在高於洗衣槽 3及外槽i之低水位P2之上的㈣，並捕捉其至水槽洗濯液 10 中。 由於脈動器2在步驟35中轉動_段時間，在洗濯及脫水 槽3中的水槽洗濯液被強迫自泵室13經由水循環通道收 至棉球過渡器15。由於異物在步驟33中被打碎成小片，它 15 20 ^與循環水槽洗濯液—起被帶至棉球魏㈣，並收集於 此外’由於在步驟35中脈動器2以高水位職驅動而 ,…轉動，通過棉球過濾益15的水量十分大，使得異物 偎容易地被移除。 時—接下來，在步驟36中，在操作水供應閥9及排水閥川 ^精由轉動脈動112而騎水供顧洗過程。上面步驟中未 中^欠集而殘留的異物可與排水一起排出。在步驟37 1〇而 外槽1内的水藉由在關閉水供應閥9時操作排水閥 排出。在水供應潤洗過程中，水供應閥9及排水 可 連績地或間些地操作。 所述，在水槽洗濯過程及第一攪動潤洗過程之 13 1243866 間，執行水槽轉動潤洗過程，其中水供應閥9及排水閥1〇在 洗衣槽3以低速轉動時同時操作。因此，留在脈動器2上， 洗衣槽3之外壁的底部上，以及外槽丨之内壁的底部上的異 物，可藉由同時執行水供應及排出而排出外槽1之外，以使 5接下來的潤洗過程有效地執行。 此處’水供應及排水過程可取代水槽轉動潤洗過程， 而具有大體上相同的效果，其中洗衣槽3未轉動，而水藉由 操作水供應閥9及排水閥1〇幾乎在同時供應及排出。 此外，由於在第一攪動潤洗過程中，脈動器2以小量水 1〇作刚後轉動，可產生有力量的水流，使移除的異物打碎成 小片，並为政至水槽洗濯液中，使其容易地自外槽丨中移 出，此外，由於水接下來供應至浸泡過程的水位ρι，且脈 動器2前後轉動一段時間，留在洗衣槽3及外槽丨之間低水位 P2之上的異物可被洗掉，並捕捉在水槽洗濯液中，且同時 15通過棉球過濾為15的水量增多，使得異物可被移除並收集 在棉球過濾器15中。 此外，藉由執行水供應洗濯過程，無法藉由水槽洗濯 過程及前述潤洗過裎排出或收集的異物可排出，並因而阻 止其留在洗衣機中。 20 在此實施例中，水槽轉動潤洗過程或水供應及排出過 程之一取代水槽轉動潤洗過程如上所述係在第一攪動潤洗 過程前執行。然而，該兩個過程之一的主要目的是達到有 效地排出異物至外槽1之外，其可在第二攪動潤洗過程之前 或之後執行，以達成大體上相同的效果。 14 1243866 在此實施例中，依以上所述，水供應潤洗過程係在第 二攪動潤洗過程之後。然而，矸執行此過程而不執行第二 攪動潤洗過程，大體上可達成相同的效果。 此外，在此實施例中，依上所述，水供應潤洗過程係 5 藉由操作水供應閥9及排水閥10同時供應水及排水而執 行。然而，該過程亦可僅操作水供應閥9，而水通過一溢水 孔（未顯示）而大體上產生相同的效果。 第三實施例 如第5圖所示，控制器38控制馬達6、水供應閥9、排水 10閥1〇等的操作，以控制連續的或選擇的衣物洗濯、清水及 脫水過程，並藉由使用其中包含清潔劑之水槽洗濯液而執 行水槽洗濯過程，及其後的水槽潤洗過程，以清潔洗衣槽3 及在其中谷納洗衣槽3的外槽1之内表面。水槽潤洗過程接 續地執行以下過程：第一攪動潤洗過程，其中脈動器2以較 15浸泡過程中之水小量的水轉動；第二攪動潤洗過程，其中 脈動器2以水位等於或高於浸泡過程之液面？1高的水轉 動。與上述第二較佳實施例相同的其他元件以相同標號表 示並省略其說明。 以下將說明上述洗衣機的操作。在第一授動潤洗過程 2〇中，由於脈動器2以小量水前後轉動，可產生有力量的水 流，將移除的異物打碎成小片，並分散它們至水槽洗濯液 中，使其可谷易地移除至外槽1之外。 接下來，當脈動H2在作前後轉動的一段時間時，水供 應至高於浸泡輕之水位P1料㈣，洗掉留在洗衣槽3 15 1243866 及外槽1之間低水位P2之上的異物，並捕捉其於水槽洗濯液 中。通過棉球過濾器15之水量可大於浸泡過程之水量，使 得較多的異物可在棉球過濾器15中收集並移除。 此外，由於水位高於浸泡水位P1，水槽洗濯液因在浸 5 泡過程中水流的力量而到達之洗衣槽3及外槽1的上方可被 潤洗乾淨。 上述的水槽清潔循環，即水槽洗濯及潤洗過程之操作 可以程式儲存在控制器18的儲存區中；因此，整個水槽清 潔循環可在控制器18的控制下自動地執行。 1〇 如上所述，本發明包括以下步驟：藉由使用包含清潔 劑之水槽洗濯液洗濯水槽，可轉動地配置在其底部上的脈 動器，以及外水槽的内表面；以及潤洗洗濯過的水槽及脈 動為，该洗濯步驟包括：供應包含清潔劑的水槽洗濯液至 '先衣枝水槽及外槽；執行配合脈動器間些地前後轉動的浸 15泡過程；並在浸泡過程後排出水槽洗濯液至洗衣機槽之 吏用此方法，與習知的人工方式比較，在浸泡過程中 t於脈動ϋ的前後轉動可產生水流，使得形成在洗衣機水 槽之外壁上以及外槽之内壁上的較多異物被移除；且藉由 自動化的過程，人卫的過程可以自動化過程取代，而形成 20在洗衣機中的異物可有效地移除。 j發明已藉由較佳實施例說明如上。須瞭解的是熟悉 此技藝人士可在不脫離本發明之精神及申請專利範圍所界 定之範圍下作各種改變及改良。 C ®式簡單說明】 16 1243866 第1圖為執行依據本發明之第一較佳實施例之水槽洗 濯方法的一洗衣機之垂直橫截面；

machine by removing foreign matter, such as black mold growing on it. L 前 # 支 冬 好] Background of the Invention Referring to Fig. 6, there is shown a conventional washing machine. As shown in FIG. 6, a washing tub 3 is accommodated in the outer tub, and a pulsation of 2 can be arranged on the bottom so that it can be rotated 10 times. The suspension rod 4 is suspended from the outer frame 5 of the washing machine through a suspension rod 4. The V-belt 7 drives the pulsator 2 and the washing tub 3, and the clutch 8 also serves as a speed reduction mechanism. A water supply valve 9 is used to supply water to the washing tub 3, a drain valve 10 for discharging washing liquid from the washing tub 3; and a water level detector n for detecting the internal water level of the outer tub 1. 15 The pumps 13 to 13 are arranged close to the periphery of the inner cutting edge 12 within the pulsator 2. The washing liquid in the laundry ceremony 3 is sent from the pump chamber 13 to the cotton ball filter 15 through the water circulation passage 々. The complex το member 16 is arranged above the outer groove j. The controller 17 controls the motor 6 water, the response valve 9, the drain valve 10, etc. to successively control the washing, rinsing and dehydrating cycles. 2 In the above-mentioned washing machine, the part of the dirt removed from the clothes may form a metal soap with certain ingredients of the detergent and the metal ions of the water towel of the faucet and stick to the outer tank, for example丨, the washing tank 3 and the pulsator 2. In addition, 'After the laundry cycle is repeated, the microorganisms contained in the clothes may act on the genus I', which can cause foreign matter, such as hiding outside the washing tank 3! 243866 wall; the inner wall of the outer tank 1 and the pulsation Biofilm and black mold on the lower part of the device 2. Some of these deposits can be removed by the water flow during the laundry cycle, but contaminate the laundry. Such foreign matter can be removed by adding a bleaching ingredient as its main ingredient to the laundry detergent. When the cleaning agent is used, the water supply valve 9 and the water level detector 11 are operated to supply water to the water tank 3 as high as possible. After the heart ', a detergent is added, and the pulsator 2 is rotated to dissolve the detergent. Then, by being in water for several hours, the detergent acts on the foreign matter and removes the foreign matter. After that, the drain valve 10 is operated to drain water. Next, to wash the washing tub 3, the water should reach a predetermined water level in the washing tub 3, and the pulsator 2 is rotated to perform the washing step; then, the water is discharged. 15 20 hrs However, the sink cleaning method described above has several disadvantages. That is, a long manual method of performing soaking or sink washing operations, and then automatically performing a tank washing operation are troublesome. In addition, in the sink washing operation, only the difference = 1 can be removed. In other words, the immersion operation that is only immersed in the washing liquid of the water tank is removed in the soaking operation for one hour, and the foreign matter above the water level cannot be removed due to the increased m due to the rotation of the pulsator 2. It is impossible to drain the washing machine completely through the sink washing operation; because some parts of the cycle G can be transferred to the money machine, and the clothes are contaminated under the washing clothes. [Contents of the invention] Abstract of the invention Therefore, the purpose of the present invention to perform sink cleaning is to provide a sink cleaning method, which can be performed during the sink rinse process to effectively remove foreign objects generated in the 1243866 laundry machine. According to a preferred embodiment of the present invention, a method for cleaning a washing machine having a washing tank and an outer tank is provided. The method includes the following steps: washing the washing tank with a washing liquid containing a cleaning agent, and rotatably arranged A pulsator and the inner surface of the outer tank on a bottom of the 5 washing tank; and washing the washed water tank and the pulsator, wherein the washing step includes the following steps: preparing a washing liquid containing a washing agent in the washing tank and outside In the tank; performing the soaking step of the arterial actuator before and after the fitting gap; and draining the washing liquid from the washing tank after the soaking process. 10 Brief Description of the Drawings The above and other objects of the present invention are made clearer by the description of the drawings, in which: FIG. 1 is a vertical view of a washing machine performing a sink washing method according to a first preferred embodiment of the present invention Cross section; 15 FIG. 2 is a flowchart of a sink cleaning method according to a first embodiment of the present invention; FIG. 3 is a flowchart of a sink cleaning method according to a second embodiment of the present invention; FIG. 20 is a flowchart of a sink washing process of the second embodiment; FIG. 5 is a flowchart of a sink washing method according to a third embodiment of the present invention; and FIG. 6 is a vertical cross-sectional view of a conventional washing machine. I [Square package method 3 1243866 Detailed description of the preferred embodiment The preferred embodiment of the present invention will be described in conjunction with Figures 1 to 5, wherein components similar to those of the conventional washing machine in Figure 6 are labeled with similar numbers As shown in FIG. 1, for example, the controller empties the operation of the motor 6, water supply 9, drain valve 10, etc. to control one or more washing cycles. In each cycle, the rinsing and / or dehydration processes are successively or selectively controlled. The control cry also performs a sink washing process by using a sink washing liquid containing a detergent, washing the spear with 10 and subsequent sinks to clean the washing sink 3, and a pulsator 2 rotatably disposed on the bottom thereof. And the inner surface of the outer tank 1. The sink washing process is performed by supplying liquid. The sink washing solution with a certain concentration is prepared in the washing tank 3 and the outer tank 4; performing the soaking = process', the arterial actuator 2 is turned back and forth in the middle of the process; then the drainage process is performed. 15 passes' to discharge the lotion from the washing tub 3. In the immersion process, the water level is set to a water level p which is preferably higher than a highest water level that can be achieved in the laundry washing cycle; the forward and backward rotation of the pulsator 2 and the rotation stop are performed at an intersection. In addition, after soaking, the shaking process is performed, in which the washing liquid in the washing tub 3 is stirred by the pulsator 2. 20 The operation of the washing machine will be described below with reference to Figures 1 and 2. In step shot, press the -Start switch (not shown) to start the sink washing and filling liquid supply process. In step 21 ', the water is supplied to the washing tub 3 to reach a predetermined water level through the water supply valve 9 and the water level detection rhyme, and the water level is higher than the highest water level in the laundry cycle to close the drain valve 9. In step 22, detergent 9 1243866 is added. In step 23, the motor 6 rotates the arterial actuator 2 to perform back-and-forth rotation for a predetermined period of time to dissolve the detergent, and prepares a sink washing liquid having a uniform detergent concentration. Next, it enters the immersion process, which simultaneously rotates back and forth 5 pulses to 2 'motor 6 so that the pulsator 2 is rotated by the on / off control of the controller 18 in step μ. By the forward and backward rotation of the pulsator 2, the agitating power of the washing liquid in the washing tank 3 in the washing tub 3 increases, and when the pulsator 2 is opened, the middle portion of the liquid surface inside the washing tub 3 drops, and the outside, that is, The liquid level between the washing tub 3 and the outer tub 1 rises. ίο Therefore, the liquid level between the washing tank 3 and the outer tank 1 rises to a predetermined water level ρ, so that the cleaning agent can reach the relatively high water level of the outer wall of the washing tank 3 and the inner wall of the outer tank. Conversely, in the closed state, the liquid level in the washing tank 3 rises, and the liquid level between the washing tank 3 and the outer tank 丨 drops. Thereafter, in step 25, the immersion is performed for a predetermined period of time, during which the pulse 2 is not rotated back and forth to allow the sink washing liquid to sufficiently act on the foreign matter. In step 26, the operations of steps 24 and 25 are repeated a predetermined number of times, so that the waiter β > tincture can effectively reach the foreign body, and the water flow generated by the pulsator 2 rotating back and forth can remove the foreign body. 20 y Next 'During the agitation in step 27, it is rotated by the pulsator 2 before 1' The water tank washing liquid in the washing and dewatering tank 3 is sent from the pump chamber 13 through the water 4 channel 14 to the cotton ball filter 15 Therefore, the impurities in the washing liquid in the sink are collected in the cotton ball filter 15. At the same time, the foreign matter deposited on the rear side of the pulsator 2, the pump chamber 13, the circulation path 14, etc. can also be removed and collected in the cotton ball passing device 15. 10 1243866 The next step is to enter the draining process. The drain valve 10 is operated in step 28 to drain the washing liquid from the washing tub 3, and then enter the rinse process in step 4. In this way, the water flow can be caused by the back-and-forth rotation of the gap of the pulsator 2, so that 5 more foreign matters formed on the outer wall of the washing tub 3 and the inner wall of the outer tub 1 are removed; and through automated and cumbersome steps, The automatic method is performed, and the foreign matter formed in the washing machine can be removed. In addition, during the soaking process, the preset water level is set to be higher than the highest water level in the washing cycle, and the washing liquid in the water tank is stirred by the pulsator 2 turning back and forth 10 and stopped rotating; in addition, the liquid in the washing tank 3 The middle part of the surface height decreases when the liquid level between the washing tank 3 and the outer tank 1 rises, so the 'sink washing liquid can reach and clear above the highest water level of the washing cycle and is formed on the outer wall and outside of the washing tank 3. Foreign matter on the inner wall of the tank 1. In addition, after soaking, by stirring the water 15 washing liquid in the washing tub 3 with the pulsator 2, the foreign matter removed by the soaking process can be collected in the cotton ball filter 15. In this embodiment, the water level is maintained the same during the supply and soaking of the washing liquid in the water tank. However, the water level during the supply of the washing liquid in the sink can be set, for example, the highest water level in the laundry cycle, and the water can be supplied more after the soaking process to a level higher than the southernmost water level. Under this condition, the detergent > tincture can dissolve quickly during the supply of the washing liquid in the sink. As shown in Figure 3 of the second embodiment, the controller 29 controls the operation of the motor 6, the water supply valve 9, the drain valve 10, etc. to successively or selectively control the laundry washing, rinsing, and 1243866 dehydration processes. The sink washing liquid of the detergent performs a sink washing process and a sink rinse process to clean the inner surfaces of the washing tank 3 and the washing tank 3 with the washing tank 3 loaded therein. The rinse process is performed at least once. The subsequent process is: the sink rotates and rinses, in which the water supply valve 9 and the drain valve 5 10 open at the same time when the laundry tank 3 rotates at a low speed; the first agitation process, in which the pulsator 2 A small amount of water is rotated during the soaking process when the drain valve 10 is closed; a second agitation process in which the pulsator 2 is rotated with a moderate amount of water during the soaking process; and the drain process is performed when the drain valve 10 is opened. In addition, it is better to perform a water supply rinsing process before a drainage process of the rinsing process. The other elements are the same as the aforementioned first preferred embodiment; therefore, the elements are denoted by the same reference numerals, and descriptions thereof are omitted. The operation of the above-mentioned washing machine will now be described with reference to Figs. After completing the washing process of the sink, enter the following sink cleaning process: First, in step 31, perform a sink rotating rinse process, in which the water supply valve 9 and the drain valve 1015 are opened or the laundry tank 3 is rotated at a low speed. Open or operate at the same time, so that the end of the washing process of the sink is maintained, for example, on the pulsator 2, the bottom of the outer wall of the washing tank 3 and the bottom of the inner wall of the outer tank 1 are discharged together with the drainage. In addition, the water supply and drainage processes can be performed instead of performing the sink rotation and washing process, in which the laundry tank 3 does not rotate when water is supplied and drained by operating the water supply valve 9 and the drainage valve 10 almost simultaneously 20. Next, water is supplied to the low water level P2 by the water supply valve 9 and the water level detector η in step 32, and at this time, the drain valve 10 is closed. Next, in step 33, the first agitating and washing process is performed, in which the motor 6 is driven to rotate the pulsator 2 back and forth for a predetermined time, causing the foreign matter maintained between the washing tub 3 and the outer 12 1243866 tub 1 to be captured in Sink washing solution. At this time, since the pulsator 2 is rotated back and forth with a small amount of water, a powerful water flow 'can be formed to break the removed foreign matter into small pieces. Next, in step 34, water is supplied by the water supply valve 9 and the water level side device ^ 5, and the drain valve 10 is closed until it reaches the water level P1 of the soaking process in the sink washing process, and the water level is higher than the i-th dynamic rinse Passing water level P2; in step 35, a second fluttering and washing process is performed, in which the pulsator 2 is rotated back and forth by the motor 6-for a period of time, the "wash out" is left above the washing tank 3 and the outer tank i The radon above the low water level P2 is captured in the sink washing liquid 10. Since the pulsator 2 is rotated for a period of time in step 35, the washing liquid in the washing tank in the washing and dewatering tank 3 is forced to be collected from the pump chamber 13 to the cotton ball transition device 15 through the water circulation passage. Since the foreign object was broken into small pieces in step 33, it was taken to the cotton ball Wei Wei together with 15 20 ^ and the circulating bath washing liquid, and collected in addition. 'Since the pulsator 2 is driven at a high water level in step 35, ... Turning, the amount of water filtered through the cotton ball 15 is very large, so that the foreign matter can be easily removed. Hours—Next, in step 36, the water supply valve 9 and the drain valve 207 are operated by the arterial artery 112 to ride water for washing. The foreign matter remaining in the above steps without being collected can be discharged together with the drainage. At step 37, the water in the outer tank 1 is discharged by operating the drain valve when the water supply valve 9 is closed. During the water supply rinsing process, the water supply valve 9 and the drainage can be operated continuously or intermittently. As mentioned above, the rotating and washing process of the water tank is performed between 13 1243866 of the washing process of the water tank and the first agitation and washing process, wherein the water supply valve 9 and the drain valve 10 are operated simultaneously when the washing tank 3 is rotated at a low speed. Therefore, foreign matter remaining on the pulsator 2, the bottom of the outer wall of the washing tub 3, and the bottom of the inner wall of the outer tub 丨 can be drained out of the outer tub 1 by performing water supply and drainage simultaneously, so that 5 The subsequent rinse process is effectively performed. Here, the water supply and drainage process can replace the rotating and rinsing process of the water tank, and have substantially the same effect, in which the washing tank 3 is not rotated, and the water is supplied and operated at almost the same time by operating the water supply valve 9 and the drainage valve 10 discharge. In addition, during the first agitation and washing process, the pulsator 2 is rotated with a small amount of water 10 shortly afterwards, which can generate a powerful water flow, break the removed foreign matter into small pieces, and wash the liquid into the sink. So that it can be easily removed from the outer tank 丨 In addition, because water is subsequently supplied to the water level ρm of the soaking process, and the pulsator 2 is rotated back and forth for a period of time, it remains at the low water level P2 between the laundry tank 3 and the outer tank 丨The above foreign matter can be washed away and captured in the washing liquid of the sink, and at the same time, the amount of water filtered by 15 through the cotton ball is increased, so that the foreign matter can be removed and collected in the cotton ball filter 15. In addition, by performing the water supply washing process, the foreign matter that cannot be discharged or collected by the water tank washing process and the aforementioned rinse process can be discharged, and thus it is prevented from remaining in the washing machine. 20 In this embodiment, instead of the sink rotating rinse process, one of the sink rotating rinse process or the water supply and discharge process is performed before the first agitated rinse process as described above. However, the main purpose of one of the two processes is to effectively discharge foreign matter out of the outer tank 1, which can be performed before or after the second agitating and rinsing process to achieve substantially the same effect. 14 1243866 In this embodiment, as described above, the water supply rinse process is performed after the second agitated rinse process. However, by performing this process without performing the second agitation rinse process, substantially the same effect can be achieved. Further, in this embodiment, as described above, the water supply and rinse process 5 is performed by operating the water supply valve 9 and the drain valve 10 to supply water and drain water simultaneously. However, this process can also operate only the water supply valve 9 and water passes through an overflow hole (not shown) to produce substantially the same effect. The third embodiment is shown in FIG. 5. The controller 38 controls the operation of the motor 6, the water supply valve 9, the drain 10 valve 10, and the like to control the continuous or selected laundry washing, clear water and dehydration processes, and by using The sink washing liquid containing the detergent is used to perform the sink washing process and the subsequent sink washing process to clean the inner surface of the washing tub 3 and the outer tub 1 of the laundry washing tank 3 therein. The sink rinse process successively performs the following processes: the first agitated rinse process, in which the pulsator 2 rotates with a smaller amount of water than the water in the 15 soaking process; the second agitated rinse process, in which the pulsator 2 with a water level equal to or Above the liquid level in the soaking process? 1 high water turns. The other elements which are the same as those of the above-mentioned second preferred embodiment are denoted by the same reference numerals and their explanations are omitted. The operation of the above-mentioned washing machine will be described below. In the first initiating rinse process 20, because the pulsator 2 rotates back and forth with a small amount of water, it can generate a powerful water flow, break the removed foreign matter into small pieces, and disperse them into the sink washing liquid, so that It can be easily removed out of the outer tank 1. Next, when the pulsating H2 rotates back and forth for a period of time, the water is supplied above the water level P1 of the immersion light, and the foreign matter remaining above the low water level P2 between the washing tank 3 15 1243866 and the outer tank 1 is washed away. And capture it in the sink washing liquid. The amount of water passing through the cotton ball filter 15 may be greater than the amount of water in the soaking process, so that more foreign matter can be collected and removed in the cotton ball filter 15. In addition, since the water level is higher than the soaking water level P1, the washing liquid in the water tank can be cleaned and washed above the washing tank 3 and the outer tank 1 due to the force of the water flow during the soaking process. The above-mentioned sink cleaning cycle, that is, the operation of the sink washing and rinsing process can be stored in the storage area of the controller 18 programmatically; therefore, the entire sink cleaning cycle can be automatically executed under the control of the controller 18. 10. As described above, the present invention includes the steps of washing the water tank by using a water tank washing liquid containing a detergent, a pulsator rotatably disposed on the bottom thereof, and the inner surface of the outer water tank; The sink and pulsation are as follows. The washing step includes: supplying a sink washing solution containing a detergent to the 'first clothes' sink and the outer tank; performing a 15-soak process in which the pulsator is rotated forward and backward; and the bath is discharged after the soaking process. In this method, the liquid to the washing machine tank is compared with the conventional manual method. During the soaking process, the t-pulsation can rotate back and forth to generate a water flow, so that more water is formed on the outer wall of the washing machine tank and on the inner wall of the outer tank. Foreign matter is removed; and through the automated process, the sanitary process can be replaced by an automated process, and the foreign matter forming 20 in the washing machine can be effectively removed. The invention has been described above with reference to a preferred embodiment. It should be understood that those skilled in the art can make various changes and improvements without departing from the spirit of the present invention and the scope defined by the scope of patent application.
