Description
發明領域 本揭示是有關於一種對旋轉滾筒內之衣物的不平衡狀態進行偵測的滾筒式洗衣機。field of invention The present disclosure relates to a drum type washing machine which detects the unbalanced state of the clothes in the rotating drum.
發明背景 以往,在滾筒式洗衣機中,已知有一種偵測設置於水槽之內部的旋轉滾筒內的衣物是否不均勻分佈在旋轉滾筒之前方或後方的滾筒式洗衣機。Background of the invention In the past, among drum-type washing machines, there is known a drum-type washing machine that detects whether the clothes in the rotating drum disposed inside the water tank are unevenly distributed in front of or behind the rotating drum.
當在旋轉滾筒之前方有偏負載時,會有如下的問題。When there is an unbalanced load in front of the rotating drum, there are problems as follows.
第一個問題是,藉由水槽之前部的振動,而引起洗衣機本體之異常振動的可能性高。在洗衣機本體的投入口與水槽的開口部之間,設置有用以抑制洗滌水之漏洩的密封構件等。因此,水槽之前部的振動會容易傳達至洗衣機本體。The first problem is that the possibility of abnormal vibration of the washing machine body is high due to the vibration of the front part of the water tank. Between the inlet of the main body of the washing machine and the opening of the water tank, a sealing member and the like for suppressing leakage of washing water are provided. Therefore, the vibration of the front part of the water tank is easily transmitted to the main body of the washing machine.
第二個問題是,前方之偏負載會對軸(shaft)賦予很大的負荷。軸是連接於旋轉滾筒之後方。因此,當在旋轉滾筒之後方有偏負載時,並不會對軸施以很大的負荷。另一方面,當在旋轉滾筒之前方有偏負載時,由於從軸到旋轉滾筒之前方為止的距離很長,因此會對軸施加很大的負荷。藉此,會有軸損傷的可能性。The second problem is that the off-center load in the front places a large load on the shaft. The shaft is connected to the rear of the rotating drum. Therefore, when there is an off-center load behind the rotating drum, no significant load is applied to the shaft. On the other hand, when there is an unbalanced load in front of the rotating drum, since the distance from the shaft to the front of the rotating drum is long, a large load is applied to the shaft. Thereby, there is a possibility of shaft damage.
日本專利特開2010-136903號公報揭示了一種從水槽之前部的振動與實驗所得的相關關係來推測偏負載的位置,以判定衣物之不平衡狀態的滾筒式洗衣機。Japanese Patent Application Laid-Open No. 2010-136903 discloses a drum type washing machine in which the position of the unbalanced load is estimated from the correlation between the vibration at the front of the sink and the experimental results to determine the unbalanced state of the clothes.
日本專利特開2010-136903號公報中之洗衣機具備:水槽,支撐於洗滌殼體內部;旋轉滾筒,旋轉自如地設置於水槽之內部;及振動偵測機構,設置於水槽之上表面前部,並偵測三維方向的振動成分。洗衣機在脫水動作中,是使用在水槽之前部偵測到的二方向的振動成分、及藉由實驗所得的水槽之後部的振動成分對水槽之前部的振動成分的相關關係,來特定出水槽之偏負載的位置。The washing machine in Japanese Patent Application Laid-Open No. 2010-136903 is equipped with: a water tank supported inside the washing shell; a rotating drum freely rotatably installed inside the water tank; And detect vibration components in three-dimensional directions. During the dehydration operation of the washing machine, the vibration components in two directions detected at the front of the water tank and the correlation relationship between the vibration components at the rear of the water tank and the vibration components at the front of the water tank obtained through experiments are used to determine the direction of the water outlet tank. Offset load position.
發明概要 然而,以往的構成由於是依據實驗所得的相關關係來推測偏負載的位置,因此特定出偏負載的位置的精確度低。所以,會有不平衡狀態是存在於前方或後方被錯誤判定的可能性。Summary of the invention However, in the conventional configuration, since the position of the off-load is estimated based on the correlation obtained through experiments, the accuracy of specifying the position of the off-load is low. Therefore, there is a possibility that the unbalanced state exists in the front or the rear and is misjudged.

在圖1中,水槽19是形成為有底圓筒狀,並配設於殼體6之內部。水槽19是藉由複數個懸架31及複數個防振阻尼器26而被彈性支撐,以使中心軸從前方朝向後方變低。
水槽19之前方部是藉由樹脂製的水槽蓋27而被覆蓋。在水槽蓋27之前方部與殼體6之前方部之間,設置有以樹脂材料所形成的密封構件23。水槽蓋27及水槽19構成水槽單元37。另外,形成密封構件23的樹脂材料中,有包含合成橡膠材料。In FIG. 1 , the
蓋10是開閉自如地設置成覆蓋殼體6的開口。藉由將蓋10作成為開啟狀態,使用者便可以將洗滌物(衣物)取出放入旋轉滾筒17內。The
在水槽19之內部旋轉自如地配置有旋轉滾筒17。旋轉滾筒17是形成為有底圓筒狀。亦即,旋轉滾筒17具有有底圓筒的形狀。在旋轉滾筒17之側面設置有多數個通水孔18。又,在旋轉滾筒17之內壁面設置有攪拌衣物用的複數個突起板22。複數個突起板22各自在旋轉滾筒17 之內部,會隨著旋轉滾筒17的旋轉而將衣物提起至預定的高度,然後使已提起的衣物朝下方落下。Inside the
軸24的一端是固定於旋轉滾筒17之底部。軸24是設置成通過旋轉滾筒17的中心軸,並延伸至旋轉滾筒17的背面。軸24是藉由軸承25而被支撐成貫通水槽19之底部。又,在水槽19之底部配設有軸承盒15。軸承盒15會收納軸承25。軸24的另一端是貫通軸承盒15,並固定於已配置在軸承盒15之下部的滾筒皮帶輪28。One end of the
又,在水槽19之下方配設有滾筒驅動馬達21。在滾筒皮帶輪28與滾筒驅動馬達21之間架設有皮帶29。滾筒驅動馬達21所造成的旋轉驅動力會透過皮帶29、滾筒皮帶輪28、及軸24而傳達至旋轉滾筒17。藉此,旋轉滾筒17便會旋轉。Moreover, the
在水槽蓋的上表面之前部配設有振動偵測裝置40。振動偵測裝置40是藉由三軸加速度感測器所構成。振動偵測裝置40會偵測沿著X軸及Y軸之水槽單元37的動作資訊。具體而言,振動偵測裝置40會取得沿著X軸及Y軸之水槽單元37的加速度的值,並從已取得之加速度的值來偵測振動振幅值。A
在殼體6之後方設置有控制部20。控制部20會依據使用者所進行之指示輸入及各部的動作狀態監視,來控制涵蓋清洗動作、沖水動作、脫水動作、及乾燥動作之一系列的運轉動作。A
接著,針對滾筒式洗衣機的動作,使用圖2A及圖2B來進行說明。Next, the operation of the front-loading washing machine will be described using FIGS. 2A and 2B .
首先,說明本實施形態中之洗滌運轉的基本動作。First, the basic operation of the washing operation in this embodiment will be described.
洗滌運轉在水槽單元37內,是藉由如下運轉所構成:清洗運轉,使浸漬於洗劑水中的衣物在旋轉滾筒17內旋轉;沖水清洗運轉,以水沖洗包含了洗劑水的衣物;及脫水運轉,將包含了水的衣物脫水。The washing operation is performed in the
首先,針對清洗運轉進行說明。藉由使用者將衣物投入旋轉滾筒17。接著,藉由使用者操作洗衣機之操作顯示部(未圖示),清洗運轉便會開始。清洗運轉開始後,會對水槽19內供給(供水)預定量的自來水。又,也會對收納有洗劑的洗劑盒(未圖示)供水,並將在水中溶解了洗劑的洗劑水投入水槽19中。供水結束後,藉由滾筒驅動馬達21使旋轉滾筒17旋轉,清洗動作便會開始。清洗動作中,衣物會被攪拌預定的清洗時間,以除去附著的髒污等。First, the cleaning operation will be described. The clothes are put into the
接著,針對沖水清洗運轉進行說明。清洗動作結束後,骯髒的洗滌水會從水槽19排出,並轉移至沖水清洗運轉。沖水清洗運轉是藉由反覆沖水清洗動作與脫水動作來進行。沖水清洗動作中,預定量的自來水會供水至水槽19內,且旋轉滾筒17會旋轉,在清洗運轉時自衣物除去的髒污與洗滌水便會從水槽19排出。針對脫水動作將於後敘述。沖水清洗運轉結束後,脫水運轉中的脫水動作便會開始。Next, the flushing washing operation will be described. After the cleaning operation is finished, the dirty washing water will be drained from the
接著,針對脫水動作進行說明。脫水動作中,藉由滾筒驅動馬達21高速旋轉,將包含於洗滌物之洗滌水脫水。當脫水動作開始後,控制部20會開始旋轉滾筒17的旋轉,並使旋轉數階段性地上升至旋轉滾筒17的旋轉數到達約800r/min為止。容置於旋轉滾筒17之洗滌物會因應於旋轉數上升,而藉由離心力貼附於旋轉滾筒17之內壁。Next, the dehydration operation will be described. During the dehydration operation, the
當旋轉滾筒17以高速旋轉時,洗滌物並未均等地貼附於旋轉滾筒17之內周壁,在旋轉滾筒17之內部,洗滌物的位置會成為不平衡狀態(不均勻的狀態),因而會有在旋轉滾筒17產生偏負載的情況。一旦產生偏負載,藉由滾筒驅動馬達21而被驅動的水槽單元37就不會進行預定的圓運動,而會進行像是描繪楕圓的旋轉運動。本實施形態中,為了偵測該不平衡狀態,會進行不平衡判定。When the
不平衡判定會在旋轉滾筒17的旋轉數到達約800r/min後開始。不平衡判定中,會從旋轉滾筒17及水槽單元37的振動軌跡來偵測不平衡狀態。Unbalance judgment starts after the rotation speed of
圖2A是在實施形態1中的滾筒式洗衣機的旋轉滾筒之前方產生偏負載時的示意圖。圖2B是在實施形態1中的滾筒式洗衣機的旋轉滾筒之後方產生偏負載時的示意圖。另外,在圖2A及圖2B中,與圖1同樣地,亦將洗衣機本體之前後方向稱為X軸,上下方向稱為Y軸,左右方向稱為Z軸。另外,該等之軸只是為了方便而顯示,並不限定本揭示之任何內容。Fig. 2A is a schematic diagram of a case where an unbalanced load is generated in front of the rotating drum of the front-loading-type washing machine according to the first embodiment. Fig. 2B is a schematic diagram of the case where an unbalanced load is generated behind the rotating drum of the front-loading-type washing machine in the first embodiment. In addition, in FIG. 2A and FIG. 2B , similar to FIG. 1 , the front and rear direction of the washing machine body is also referred to as the X axis, the up and down direction is referred to as the Y axis, and the left and right directions are referred to as the Z axis. In addition, these axes are shown for convenience only, and do not limit any content of this disclosure.
當洗滌物50偏於旋轉滾筒17之前方時,旋轉滾筒17會像描繪以旋轉滾筒17之後方的旋轉中心A為中心的楕圓一樣地搖晃。另外,旋轉中心A會依洗滌物50的位置或量而採不同的位置。伴隨旋轉滾筒17的搖晃,水槽單元37及振動偵測裝置40也會像描繪以旋轉滾筒17之後方的旋轉中心A為中心的楕圓一樣地振動。When
因此,當從側邊觀看水槽單元37時,如圖2A所示地,水槽單元37之前方會像大幅地上下運動一樣地振動。Therefore, when the
同樣地,當洗滌物60偏於旋轉滾筒17之後方時,旋轉滾筒17會像描繪以旋轉滾筒17之前方的旋轉中心B為中心的楕圓一樣地搖晃。Similarly, when
因此,當從側邊觀看水槽單元37時,如圖2B所示地,水槽單元37之後方會像大幅地上下運動一樣地振動。Therefore, when the
接著,使用圖3A及圖3B,針對在產生了偏負載的情況下,振動偵測裝置40所偵測的振動振幅值進行說明。Next, using FIG. 3A and FIG. 3B , the vibration amplitude value detected by the
圖3A是繪製了在實施形態1中的滾筒式洗衣機中,當偏負載存在於前方時,振動偵測部所檢測到的振動振幅值的示意圖。圖3B是繪製了在實施形態1中的滾筒式洗衣機中,當偏負載存在於後方時,振動偵測部所檢測到的振動振幅值的示意圖。另外,在圖3A及圖3B中,與圖1同樣地,將洗衣機本體之前後方向定義為X軸,上下方向定義為Y軸。又,在圖3A及圖3B中,將X軸方向的振動振幅值定義為X,Y軸方向的振動振幅值定義為Y。FIG. 3A is a schematic diagram plotting vibration amplitude values detected by a vibration detection unit when an unbalanced load exists in front of the drum-type washing machine in
圖3A中的振動振幅值的軌跡是成為右側較高的楕圓。將X之最大值定義為Xmax,最小值定義為Xmin。將X=Xmax時之Y的值定義為Y1,X=Xmin時之Y的值定義為Y2。當偏負載存在於洗衣機之前方時,Y1會變得比Y2更大。The locus of the vibration amplitude value in FIG. 3A is a higher ellipse on the right. The maximum value of X is defined as Xmax, and the minimum value is defined as Xmin. The value of Y when X=Xmax is defined as Y1, and the value of Y when X=Xmin is defined as Y2. When a partial load exists in front of the washing machine, Y1 will become larger than Y2.
另一方面,圖3B中的振動振幅值的軌跡是成為左側較高的楕圓。同樣地,若求出偏負載存在於洗衣機之後方時的Y1及Y2,Y1會比變得比Y2更小。On the other hand, the locus of the vibration amplitude value in FIG. 3B is an ellipse with a higher left side. Similarly, when Y1 and Y2 are obtained when an unbalanced load exists behind the washing machine, Y1 becomes smaller than Y2.
因此,藉由比較Y1與Y2,可以容易地判別偏負載在前方或後方。Therefore, by comparing Y1 and Y2, it can be easily judged whether the partial load is in the front or the rear.
接著,使用圖4,針對不平衡判定的判定處理進行說明。Next, the determination processing of the unbalance determination will be described using FIG. 4 .
在旋轉滾筒17的旋轉數到達約800r/min起經過預定時間後,判定處理便會開始(S100)。After a predetermined time elapses after the rotational speed of the
首先,作為初始值,控制部20會將Xmax設定為「0」,並將Xmin設定為「0」。同樣地,控制部20會將Y1設定為「0」,並將Y2設定為「0」(S200)。First, the
接著,控制部20會取得藉由振動偵測裝置40所檢測到的振動振幅值(S300)。Next, the
接著,控制部20會判定所取得之X的值是否比Xmax更大(S310)。在S310中,若判定所取得之X的值比Xmax更大(S310,Yes),控制部20會將X的值代入Xmax,並且將Y的值代入Y1(S320),處理便會轉移至S400。在S310中,若判定所取得之X的值並未比Xmax更大(小或相等)(S310,No),處理便會轉移至S330。Next, the
接著,控制部20會判定所取得之X的值是否比Xmin更小(S330)。在S330中,若判定所取得之X的值比Xmin更小(S330,Yes),控制部20會將X的值代入Xmin,並且將Y的值代入Y2(S340),處理便會轉移至S400。在S330中,若判定所取得之X的值並未比Xmin更小(大或相等)(S330,No),處理便會轉移至S400。Next, the
接著,控制部20會判定反覆處理之經過時間是否已到達預定時間(S400)。若判定反覆處理之經過時間並未到達預定時間(S400,No),控制部20會再次取得藉由振動偵測裝置40所檢測到的振動振幅值(S300),並進行X的值的判定(S310、S330)。Next, the
若判定反覆處理之經過時間已到達預定時間(經過了預定時間)(S400,Yes),控制部20會比較Y1的值與Y2的值之大小(S500)。若判定Y1的值比Y2的值更大或Y1的值與Y2的值相等(S500,No),控制部20便會判定偏負載在前方(S510)。接著,控制部20會將振動振幅值的容許值設定成相對低於預定的容許值的值即小容許值(S520),並結束判定處理。If it is determined that the elapsed time of the repeated processing has reached the predetermined time (elapsed predetermined time) (S400, Yes), the
同樣地,若判定Y1的值比Y2的值更小(S500、Yes),控制部20便會判定偏負載在後方(S530)。此外,控制部20會將振動振幅值的容許值設定成相對高於預定的容許值的值即大容許值(S540),並結束判定處理。Similarly, if it is determined that the value of Y1 is smaller than the value of Y2 (S500, Yes), the
另外,X的值及Y的值之更新時間(S300~S400)宜設定為旋轉滾筒17之旋轉周期的1/8以下。藉此,可保證判定的精確度。In addition, the update time (S300-S400) of the value of X and the value of Y is preferably set to 1/8 or less of the rotation period of the
另外,反覆處理中之預定時間宜設定地比旋轉滾筒17之旋轉周期更長。藉由從S300到S400的反覆處理,可以求出Xmax、Xmin、Y1、及Y2。In addition, the predetermined time in repeated processing is preferably set to be longer than the rotation period of the
判定處理結束後,控制部20會藉由振動偵測裝置40來進行振動振幅值的偵測,並與容許值比較。此時,作為振動振幅值,是使用分別沿著X軸、Y軸、及Z軸的最大值與最小值。同樣地,作為容許值,也是設定了分別沿著X軸、Y軸、及Z軸的值。After the determination process is completed, the
另外,本實施形態中,在X軸、Y軸、及Z軸中之任一軸中,當偵測到的振動振幅值超過容許值時,控制部20會判定振動振幅值比容許值更大。然而,控制部20在X軸、Y軸、及Z軸之所有的軸中,僅在振動振幅值超過容許值時,判定振動振幅值比容許值更大亦可。In addition, in this embodiment, when the detected vibration amplitude exceeds the allowable value in any of the X-axis, Y-axis, and Z-axis, the
當判定偵測到的振動振幅值比容許值更小或偵測到的振動振幅值與容許值相等時,控制部20會持續脫水動作。當判定偵測到的振動振幅值比容許值更大時,控制部20會停止旋轉滾筒17的旋轉,並從脫水動作朝修正動作即修正沖水動作轉移。When it is determined that the detected vibration amplitude is smaller than the allowable value or the detected vibration amplitude is equal to the allowable value, the
首先,對旋轉滾筒17內供水,進行將洗滌物之糾纏解開的修正沖水動作。修正沖水動作結束後,便會再次開始脫水動作。First, water is supplied into the
另外,當即便反覆預定次數之修正沖水動作及脫水動作仍無法消除不平衡狀態時,控制部20會進行不平衡狀態之內容的異常通報。若已進行異常通報,使用者就必須將蓋10作成為開啟狀態,然後將旋轉滾筒17內之洗滌物取出,並解開糾纏。使用者在消除了糾纏後,將洗滌物投入旋轉滾筒17內,並將蓋10作成為關閉狀態,然後透過操作顯示部使運轉再度開始。當藉由使用者來使運轉再度開始後,控制部20會再次開始脫水動作。In addition, when the unbalanced state cannot be eliminated even if the correction flushing operation and the dehydration operation are repeated for a predetermined number of times, the
針對如以上所構成之判定處理,說明其作用。With regard to the judgment processing constituted as above, its function will be described.
當檢測到的振動振幅值比大容許值更大時,不論偏負載在前方或後方,控制部20皆會停止脫水動作並進行修正動作。When the detected vibration amplitude value is larger than the maximum allowable value, the
當檢測到的振動振幅值比大容許值更小,且比小容許值更大時,控制部20會於偏負載在前方的情況與偏負載在後方的情況下,進行不同的處理。亦即,當偏負載在前方時,控制部20會停止脫水動作並進行修正動作。另一方面,當偏負載在後方時,控制部20會持續脫水動作。When the detected vibration amplitude is smaller than the large allowable value and larger than the small allowable value, the
當偏負載在前方時,會有異音產生及軸24損傷等發生的可能性。因此,當偏負載在前方時,宜修正不平衡狀態較為理想。另一方面,當偏負載在後方時,產生異常的可能性會比較低。因此,修正沖水所造成之洗滌運轉時間的延長及水的使用過剩(水費的增加)等便會成為問題。因此,藉由將容許值設定為相對較高的大容許值,就不用進行超出必要的修正動作。When the bias load is in front, there is a possibility of occurrence of abnormal noise and damage to the
如以上所述,藉由控制部20依據偏負載的位置來切換振動振幅值的容許值,可以對不平衡狀態適當地進行處理。As described above, by the
