Description
本發明,係有關於進行衣物等之洗滌的洗衣機。The present invention relates to a washing machine for washing clothes and the like.
雖然核心家庭化的情形係出現已久,但是,最近,伴隨著少子化和高齡化,家庭的構成成員係從一個人起乃至於多世代大家庭地而日益出現更多的分類。同樣的,生活型態,也從親近大自然而希望與日曆相互配合地來伴隨著日出日落而進行飲食睡眠的型態起乃至於不在乎日夜區分地而對於興趣或實際效益更為重視的依據時間間隔之型態地而更加多樣化。Although the nuclear family has been around for a long time, recently, with the declining birthrate and aging, more and more classifications of family members have emerged from one person to a large family of multiple generations. In the same way, the life style also starts from the style of being close to nature and hoping to cooperate with the calendar to eat and sleep with sunrise and sunset, and even does not care about the difference between day and night, but pays more attention to interest or actual benefits. The type of time interval is more diverse.
反過來說,過著與洗衣服之類之家事絕緣之生活的人係為少,相反的,因應於各式各樣的髒污而對於洗衣服一事相當下功夫的人也並非為少數。然而,對於洗衣工程本身感到享受的人係為少,希望能夠盡可能地節省勞力時間並重視於髒污之去除結果的要求、需求係有著變強的傾向。On the other hand, few people live a life insulated from housework such as washing clothes. On the contrary, there are not a few people who work hard on washing clothes due to all kinds of dirt. However, there are few people who enjoy the laundry process itself. It is hoped to save labor and time as much as possible and pay attention to the requirement and demand system of dirt removal results have a tendency to become stronger.
在洗衣機處之洗劑自動投入機構,係為對於節省勞力時間有所助益的技術之其中一者。特別是,最近,液體洗劑係急速普及,就算是僅侷限於液體洗劑的自動投入機構,對於其之要求度亦為高。在洗劑自動投入機構之搭載中,係成為需要偵測出剩餘之洗劑量的技術。若是在洗劑剩餘量有所不足的狀態下仍直接繼續進行複數次之洗滌,則不但髒污不會被去除,並且如果髒污沉著於布中,則就算是在之後使用洗劑,也會發生極為難以將髒污去除的狀態。故而,若是洗劑之剩餘量為少,則係必須要在直到下一次的洗滌為止之前而對於使用者進行通知。The automatic injection mechanism of lotion in the washing machine is one of the technologies that helps to save labor and time. In particular, recently, the liquid lotion system has rapidly spread, and even if it is limited to an automatic injection mechanism of liquid lotion, the demand for it is high. In the installation of automatic lotion injection mechanism, it is a technology that needs to detect the remaining amount of lotion. If the remaining amount of lotion is insufficient and continue to wash several times, not only will the dirt not be removed, and if the dirt settles in the cloth, even if the lotion is used later, it will It is extremely difficult to remove the dirt. Therefore, if the remaining amount of lotion is small, it is necessary to notify the user before the next washing.
作為偵測出洗劑槽內之剩餘量的手法,偵測出基於剩餘量所導致的質量、液面高度等之物理量的手法係為簡單並且有效。其中,作為偵測出液面之手段,大致係可區分成2種。As a method of detecting the remaining amount in the lotion tank, the method of detecting physical quantities based on the mass and liquid level caused by the remaining amount is simple and effective. Among them, as a means of detecting the liquid level, it can be roughly divided into two types.
其中一種,係為設置因應於液面高度之變化而位移的可動部,並進而直接對於該位移作讀取或者是轉換為訊號並進行判別之方法。One of them is a method of setting a movable part that is displaced in response to changes in the liquid level, and then directly reading the displacement or converting it into a signal and discriminating it.
另外一種,係為偵測出因應於液面高度而改變的物理量並進行判定之方法。The other method is to detect and determine the physical quantity that changes in response to the height of the liquid level.
在關連於前者之專利文獻1中,係記載有下述一般之構成,其係由「內藏有引線開關9之支柱11、和配設於其之周圍並藉由液面而上下移動並且將內部之引線開關9作ON/OFF之磁性體浮標12、以及設置在支柱11之下部處之重錘部13」所構成,並構成為「設置在槽內之浮標開關,係將其之支柱形成為至少使下部沉入至槽內的液體中並於槽部之底面處成為載置狀態,並且從支柱而將引線導出而導引至槽外」。In
在關連於後者之專利文獻2中,係記載有一種電洗衣機,其係「具備有具有熱阻器之液面偵測手段,並構成為根據熱阻器之電性特定之變化來偵測出容器內之液體洗劑之位移」。

[發明所欲解決的課題][The problem to be solved by the invention]
在專利文獻1所記載之液面偵測裝置中,若是在支柱浸水之後使浮標降下,則支柱與浮標間之空隙係會被液所充滿,在含有揮發成分之液體洗劑的情況時,係會隨著揮發成分之發散而發生固著。又,若是設為並不使浮標浸水地而恆常在液面高度附近處浮動者,則由於係必須要將支柱與浮標的滑動高度範圍增大,因此,為了將磁性體之磁力傳導至內藏於支柱中之讀取開關處,係並無法將滑動部之空隙作充分的展開,而容易發生固著。相反的,若是將浮標之滑動高度範圍縮窄並構成為僅能夠在某一液面高度處而進行偵測者,則當在槽內存在有充分之液的狀態(液面完全地位置於較浮標之上限高度而更上方處的狀態)下,浮標係成為在被淹沒的狀態下而停留於上限高度處,並容易發生固著。又,起因於將浮標之滑動高度範圍縮窄一事,在槽之底面附近處係成為恆常停留有磁性體,從磁性體而來之磁力線係會對於框體內之其他的電性製品造成影響。In the liquid level detection device described in
在專利文獻2所記載之熱阻器方式中,當構成為能夠將洗劑槽從本體而卸下並進行洗淨的情況時,係需要進行對於熱阻器之供給電源的纜線之裝卸。使用便利性係為差,並且亦成為需要考慮有針對通電之有無的安全對策。In the thermoresistor method described in
又,一般而言,由於槽之內容積係直接關連於能夠填充液體洗劑之實際容積,因此,在槽之滿液時的偵測手段之佔據容積係以越小為越理想,就算是在使用有浮標的情況時,亦以越小為越理想。相反的,在將浮標之高度變化利用於偵測中的情況時,相對於液面變動之浮標的安定性亦係成為必要。In addition, generally speaking, since the internal volume of the tank is directly related to the actual volume that can be filled with liquid lotion, the smaller the occupied volume of the detection means when the tank is full, the better, even if it is When using buoys, the smaller is the better. On the contrary, when the height change of the buoy is used for detection, the stability of the buoy relative to the fluctuation of the liquid level is also necessary.
故而,本發明之目的,係在於提供一種難以受到相對於作為測定對象之液面的變動之影響而能夠進行安定的液面偵測之洗衣機。 [用以解決課題之手段]Therefore, the object of the present invention is to provide a washing machine that is difficult to be affected by the fluctuation of the liquid level as the measurement object and can perform stable liquid level detection.

以下,使用圖面,針對實施例作說明。在洗滌工程中,由於就算是在滾筒式洗衣機的情況時,基本上亦係為與將裝入洗滌物之籃的出入口設為上方並將旋轉馬達收容於下方並且相對於設置面而將籃之旋轉主軸設為略垂直的所謂縱型洗衣烘乾機(以下,稱作縱型洗衣烘乾機)相同之工程,因此,在以下之實施例中,係使用滾筒式洗衣烘乾機來進行說明。 圖1,係為有關於本發明之第1實施例者,並對於滾筒式洗衣烘乾機之外觀立體圖作展示。又,圖2,係為有關於本發明之第1實施例者,並為對於滾筒式洗衣烘乾機之內部構造作展示的右側面之概略剖面圖。Hereinafter, the drawings are used to describe the embodiments. In the washing process, even in the case of a drum-type washing machine, it is basically the same as setting the inlet and outlet of the laundry basket to the upper side, and accommodating the rotating motor below, and placing the basket in opposition to the installation surface. The so-called vertical type washer and dryer (hereinafter referred to as the vertical type washer and dryer) with a slightly vertical rotation spindle is the same process. Therefore, in the following embodiments, a drum type washer and dryer is used for description. . Fig. 1 is related to the first embodiment of the present invention, and shows a perspective view of the appearance of a drum-type washing and drying machine. In addition, FIG. 2 is a schematic cross-sectional view of the right side of the first embodiment of the present invention, showing the internal structure of the drum-type washing and drying machine.
首先,針對外觀以及概略構造作簡單的說明。在基體1h之上部處,係將主要藉由鋼板和樹脂成形品所作成的側板1a以及補強板(未圖示)作組合並構成骨架,並且進而於其之上安裝前面罩1c、下部前面罩1f、上面罩1e,藉由此,而形成框體1。在前面罩1c處,係被設置有使洗滌物207進出之門9,在背面處,係被安裝有背面罩1d。First, a brief description of the appearance and schematic structure will be given. On the upper part of the
在圖1所示之框體1之內側處,係如同圖2中所示一般,於略中央部處具備有外槽2。外槽2,係藉由下部之複數個的減震器5而被作支持。在被可旋轉地設置於外槽2之內側處的滾筒3中,係打開門9並投入洗滌物207。門9本身,係為在門框9b處固定有門玻璃9a者,並藉由樞軸9c,而被安裝在框體處(參考圖1)。在可旋轉之滾筒3之開口部之外周處,係被設置有為了將起因於脫水時之洗滌物207的不平衡所導致之震動降低的流體平衡子208。又,在滾筒3之內側處,係被設置有將洗滌物207舉升之複數個的提昇器209。可旋轉之滾筒3,係經由被與金屬製凸緣210作了連結的主軸211,而被與滾筒驅動用之馬達M10a直接作連結。在外槽2之開口部處,係被安裝有由彈性體所成之橡膠製之蛇腹管10。此橡膠製之蛇腹管10,係發揮維持外槽2內與門9之間之水密性的功用。藉由此,來謀求在洗衣、洗清以及脫水時之漏水的防止。可旋轉之滾筒3,係於身為側壁之圓筒部處具備有離心脫水以及通風用之多數的小孔(未圖示)。On the inner side of the
用以將洗滌水一直上汲至外槽2之上部處並散佈於滾筒3內的洗滌物207處之循環幫浦18,係被固定在較外槽2而更下部之框體的基體1h側處。洗滌水,係從被設置在外槽下部處之受水部54的排水口21起,來通過絲屑濾網222而進入至循環幫浦18之吸入口側處,並在藉由循環幫浦18而被作了升壓之後,從散水噴嘴223來朝向滾筒3內進行散水。又,在受水部54之底部處為了進行排水所設置的排水口21,係經由絲屑濾網222與排水閥V1,而與排水軟管26相通,並能夠將受水部54內之水排水。The
另一方面,溢流軟管205,係被安裝於外槽之前部處,並在排水閥V1之面前而與從排水口21而來之連結軟管(未圖示)相會合。亦即是,若是排水閥V1成為開,則溢流軟管205係成為被與排水軟管26相通連之構成。在相較於水密性而更為重視相對於水壓之上升之安全性的情況時,亦即是當水量相較於安裝有溢流軟管205之特定之水位而更為增加的情況時,就算是採用以不論是在何種情況均能夠強制性進行排水的方式來將溢流軟管205設置在較排水閥V1而更下游側處並使其與排水軟管26相通連之構成,也不會有任何的問題。On the other hand, the
將氣流導引至滾筒3內之洗滌物207處的送風管路29、和身為送風手段之送風風扇20,係從外槽2分離地而被固定(未圖示)在框體1處。吹出噴嘴203,係在外槽2處,被固定於當從洗衣烘乾機正面作觀察時較能夠旋轉之滾筒3之中心軸而更上側處並且當從洗衣烘乾機側面作觀察時為靠向正面的前側之位置處。前述吹出噴嘴203與溫風加熱器213之出口,係藉由柔軟構造之橡膠製之蛇腹管212,而藉由會使其之長邊伸縮方向相對於外槽2而成為略垂直的配置來作連接,並吸收外槽2之震動。在排水口21、送風風扇20之吸氣口(未圖示)以及吐出口(未圖示)處,係被設置有溫度感測器(未圖示)。身為本實施例之加熱手段的其中一者之溫風加熱器213,係因應於需要而用以對於送風溫度作調節。The
接著,針對從洗滌起而至烘乾工程為止,作簡單的說明。圖3,係為對於在第1實施形態例之滾筒式洗衣乾衣機中的洗滌運轉(洗衣~洗清~脫水)之運轉工程作說明之工程圖。又,圖4,係為對於對洗滌烘乾運轉進行控制的控制裝置100之構成作展示之區塊圖。Next, a brief description will be given from the washing process to the drying process. Fig. 3 is a process diagram illustrating the operation process of the washing operation (washing-washing-dehydration) in the drum-type washer-dryer of the first embodiment. 4 is a block diagram showing the structure of the
控制裝置100(運轉控制手段),係為對於馬達M10a以及供水單元15進行控制並進而因應於設定而對於洗劑自動投入單元301進行控制而成為能夠實行洗衣運轉,並且亦進行根據電導度檢測手段4所檢測出的外槽2內之液體之電導度而進行的電導度之算出、在液體內所含有的柔軟劑之有無之判定(相對於基準濃度之判別)、脫水工程之縮短之判定、洗清工程之縮短之判定等的裝置。如同圖4中所示一般,控制裝置100,係藉由微型電腦(以下,稱作「微電腦」)110、驅動電路、操作開關12、13和從電導度檢測手段4以及各種感測器而來之輸入電路等,而構成之。微電腦110,係接收使用者之操作以及在洗滌工程、烘乾工程中之各種資訊訊號。微電腦110,係經由驅動電路,而被與馬達M10a、供水電磁閥16、排水閥V1、送風風扇20等作連接,並對於此些之開閉、轉動、通電作控制。又,係為了對於使用者通知關連於滾筒式洗衣機之資訊,而對於顯示器14和蜂鳴器(未圖示)等作控制。The control device 100 (operation control means) controls the motor M10a and the
若是選擇洗滌或洗滌烘乾形成並開始運轉,則係將被作了投入的洗劑或者是當被設定有洗劑自動投入的情況時將對應於進行感測所判定出的負載之洗劑投入,並從洗滌工程起而開始。藉由洗劑自動投入單元301所投入的洗劑量,係根據在身為壓縮機之供給幫浦237處的每單位時間之吐出量與供給幫浦237之動作時間,來進行估計。If washing or washing and drying is selected and the operation is started, the lotion that has been put in will be put in or the lotion corresponding to the load determined by the sensing will be put in when it is set to automatically put in the lotion. , And started from the washing project. The amount of lotion injected by the automatic
具體而言,工程控制部112,係驅動馬達M10a而使滾筒3作旋轉,並使衣物重量算出部114算出注水前之洗滌物207的重量(布量)。電導度測定部115,係檢測出被供水之水的電導度(硬度)。又,係藉由被設置在外槽2之下部(例如,排水口21)處的溫度感測器T1,而檢測出被供水之水的溫度。洗劑量、洗衣時間決定部116,係基於所檢測出的布量、在電導度測定部115處使用從電導度檢測手段4而來的檢測值所求取出之水的電導度(硬度)、水的溫度,而藉由映射(map)檢索,來決定所投入的洗劑量和運轉時間。之後,工程控制部112,係將所決定的洗劑量、運轉時間顯示在顯示器14處。此時,若是被選擇有洗劑自動投入,則係將身為特定量之洗滌液的洗劑自動投入。以下,係以具備有洗劑自動投入設定一事作為前提,來進行說明。Specifically, the
洗滌工程,在本實施例中,基本上係被大致區分為洗劑溶解工程、前置洗衣工程、正式洗衣工程,進而,正式洗衣工程。係被區分為第1正式洗衣工程以及接續於此之第2正式洗衣工程,但是,就算是並未針對運轉之經過而對各個工程明確地作區分,在功能上而言也不會有任何的問題,又,就算是將後述之工程中的動作之一部分省略,對於作為洗滌工程之全體的功能而言也不會有差異。In this embodiment, the washing process is basically divided into a lotion dissolving process, a pre-washing process, a formal washing process, and further, a formal washing process. It is divided into the first official laundry project and the second official laundry project following this. However, even if the various projects are not clearly distinguished according to the course of operation, there will be nothing in terms of function. The problem is that even if part of the operation in the process described later is omitted, there will be no difference in the overall function of the washing process.
洗劑溶解工程,係為提示對應於洗滌開始時之藉由布量感測所判定出的負載之洗劑投入量,並藉由水來將從外部所投入或者是被自動投入的洗劑溶解,並且散佈於滾筒3內之洗滌物207處的工程。The lotion dissolving process is to show the amount of lotion corresponding to the load determined by the cloth amount sensing at the beginning of the wash, and to dissolve the lotion that is injected from the outside or automatically injected by water, and The process of spreading the
從外部投入用之洗劑投入部7起經過洗劑自動投入單元301之槽托盤302而被供水至投入路徑317(參考圖2)處的水,係在使從自動投入單元301而來之洗滌液(例如洗劑)作了混入之後,被導引至位置於滾筒3底部處之受水部54處。若是驅動循環幫浦18,則受水部54之水,係從排水口21起經由絲屑濾網222而進入至循環幫浦18之吸入口(未圖示)處。藉由循環幫浦18而被作了升壓的洗滌水,係從與循環幫浦18之出口相通連之循環吐出口而再度被送回至受水部54處(洗劑溶解工程之循環路徑)。藉由反覆進行此循環,係產生以少量的水來將洗劑作了溶解的高濃度洗劑液。一面使滾筒3進行旋轉並攪拌洗滌物207,一面將此高濃度洗劑液藉由循環幫浦18來全面性地作散佈。The water that is supplied to the input path 317 (refer to FIG. 2) through the
圖5,係為洗劑自動投入單元之立體圖。洗劑自動投入單元301,主要係由洗劑槽303、和柔軟劑槽304、和經由逆止閥313而被與此些作連接的槽托盤302、和在槽托盤302之底部外側處對於各個的槽而作了設置的磁性感測器310、以及將從逆止閥313所流出的身為洗滌液之洗劑以及柔軟劑送入至投入路徑中的供給幫浦237,而構成之。Figure 5 is a perspective view of the automatic lotion injection unit. The automatic
圖6,係為洗劑槽303之剖面圖。另外,除了洗劑或柔軟劑之供給動作以外的基本構成及控制動作等,由於係在洗劑槽303以及柔軟劑槽304處而成為共通,因此,在以下之說明中,係作為代表而以洗劑槽303為中心來進行說明。在洗劑槽303處,係收容有在洗劑槽內部相對於旋轉軸314而被可自由旋轉地作了安裝的浮標305,此浮標305,係更進而由被內裝有磁石309之浮起部306、和支持浮標305之旋轉軸314的樞軸部308、以及將樞軸部308和浮起部306作連接的臂307,而構成之。Fig. 6 is a cross-sectional view of the
浮起部306,係以在液被作了充滿的狀態下會具有某種沉入量(例如7mm)的方式,來對於浮起質量有所調整,若是浮起部306浮起,則在磁石309之底面(洗劑槽以及柔軟劑槽之底裡側)和在槽托盤302之底部處與磁石309以非接觸而作了設置的磁性感測器310之間之距離係被制定,根據磁性感測器310所接收之磁通量密度,係能夠得到磁性感測器310之輸出。亦即是,基於液面高度,由於磁石309之底面的位置係被制定,因此,若是液面為安定,則磁性感測器310之輸出亦為安定。又,由於係藉由磁通量密度之變化來偵測出相對於液面之浮起部306之高度,因此,係成為在液與磁性感測器310為非接觸下之測定。因此,從槽托盤302起之洗劑槽303和柔軟劑槽304之裝卸,係能夠並不伴隨電性配線之裝卸地來進行。浮標305內之磁石309之配置,係設為在浮標305為位置於動作範圍之最下部處的狀態下,會將S極或N極之磁極朝向設置在收容洗劑槽303以及柔軟劑槽304的槽托盤302之底部處之磁性感測器310側的配置。The floating
另外,磁極之選擇,係配合於磁性感測器310之特性來作選擇,但是,浮標305之基本動作係並不會改變。藉由設為此種構成,由於就算是發生有在旋轉軸314方向上之磁性感測器310與磁石309的位置偏移,磁極也能夠維持於基本上而言為朝向磁性感測器310側之布局,因此,藉由磁性感測器310所接收的磁通量密度之變動係被抑制為小,而能夠將對於磁性感測器310之輸出的影響縮小。進而,藉由因應於必要而將磁石309之剖面形狀如同圖5之洗劑槽303之浮標305之磁石309一般地來相對於旋轉軸314之軸方向而設為長,係能夠相對於旋轉軸314方向之磁石309與磁性感測器310之位置偏移而確保有更安定的磁性感測器310之輸出。In addition, the selection of the magnetic pole is selected in accordance with the characteristics of the
隨著洗劑被使用,液面係變得較浮標305之沉入深度而更淺,浮起部306係與洗劑槽303之底面作接觸。在所謂的觸底狀態下,磁石309與磁性感測器310係身為最為接近的狀態,若是液被較此狀態而更為充滿,則浮起部306係成為伴隨著以樞軸部308作為中心軸並在洗劑槽303內描繪出圓弧一般的軌跡而作了浮起的狀態。因此,從槽托盤302起之對於其周圍(框體內)的磁通量之影響會變大的情況,係為浮起部306身為觸底狀態時(磁石309之磁極最為接近洗劑槽303之內壁的狀態),在除此之外的狀態下,由於磁石309係描繪出收斂於從洗劑槽303之側壁或底壁起而某種程度靠向內側的軌道,因此,係能夠將對於槽托盤302周圍之電性零件等的磁通量之影響抑制為小。As the lotion is used, the liquid level becomes shallower than the sinking depth of the
又,在本實施例中,在洗劑槽303之底部處,係相對於洗劑槽303之高度方向而設置有傾斜,而特別是在液面為低之區域中將相對於液的減少程度之液面高度變化設為大。藉由此,當洗劑之剩餘量成為少時,由於係能夠將相對於液之減少程度的磁石309之移動增大,因此係能夠將相對於磁性感測器310之磁通量密度的變化比例增大。Moreover, in this embodiment, the bottom of the
又,關於浮標305之浮起部306的形狀,係將浮標305之成為旋轉軸314之方向的浮標305之寬幅,設為同方向之槽寬幅的70%以上,或者是相對於浮標305之在旋轉軸314周圍的圓運動中之周方向長度、亦即是相對於浮標305之長度,而將浮標305之寬幅設為0.7倍以上。在液面為上升的狀態下,浮標305之浮起部306的沉入深度係為深,但是,若是液面逐漸下降,則沉入量係逐漸變淺(沉入之容積係為略相同)。此時,若是如同上述一般地而預先確保有浮標305之寬幅,則當藉由浮標305之底面與液面所形成之沉入角度為相同的情況時,係能夠將沉入深度之變化量縮小。藉由預先將浮標305之浮起部306的寬幅相對於長度而設為0.7倍以上,相對於伴隨著液面降低所產生的浮起部306之沉入變化,係能夠對於浮標305之上下方向的變動作抑制並使其安定化。Regarding the shape of the floating
例如,在需要沉入容積7mL之浮起部306處,當在長度50mm、寬幅20mm(相對於長度而為0.4倍)的情況下而沉入角度從45度變化為30度的情況時,沉入深度係從35mm而成為30.3mm,並成為4.7mm之深度變化。另一方面,在長度50mm、寬幅35mm(相對於長度而為0.7倍)的情況下,沉入深度係從20mm而成為17.3mm,並被抑制為2.3mm之變化。For example, at the floating
又,藉由將浮標305之寬幅設為洗劑槽303之寬幅的70%以上,就算是發生有起因於外部攪亂之液面變動,亦係將自由液面之寬幅抑制於30%,藉由此,由於係能夠成為難以受到液面變動之影響,因此係能夠使浮標305之動作更為安定化。In addition, by setting the width of the
如同上述一般,較理想,係設為能夠相對於被配置在洗劑槽303之底部側處的磁性感測器310而抑制對於磁通量密度變化之外部攪亂的影響並且也能夠將基於原本之液面高度變化所導致的浮起部306之高度方向之變化比例設為順暢之移動的浮起部306之形狀。As described above, it is desirable to be able to suppress the influence of external disturbance on the change in magnetic flux density with respect to the
然而,由於磁性感測器310之輸出係會有受到液面之變動等之影響的可能性,因此,較理想,計測,係根據由與過去之計測值之間之比較所得到的推測使用量和基於供給幫浦237之可動時間所得到的推測吐出量,來對於此次的使用量作估計。故而,在本實施例中,磁性感測器310之輸出,係採用作為與液面高度之變化相對應的變化而被讀取之類比方式。However, since the output of the
在類比方式中,通常,為了並不在S極和N極處發生反轉地而進行輸出,多係會改變為使0mT偏移至施加電壓之中間電壓值處的輸出。例如,當施加電壓為5V的情況時,並未施加有磁通量的0mT時之設定輸出係成為2.5V,但是,實際上而言,係也會有起因於製品之參差而有所偏移的情形。因此,藉由施加將在並未施加有磁通量之狀態下的輸出設為2.5V之電路上的修正,係能夠將測定精確度更進一步提升。In the analog method, usually, in order to output without inverting the ground at the S pole and the N pole, the output is often changed to an output that shifts 0 mT to the intermediate voltage value of the applied voltage. For example, when the applied voltage is 5V, the set output when 0mT of the magnetic flux is not applied is 2.5V, but in fact, there may be deviations due to product variations. . Therefore, by applying a correction to the circuit that sets the output in the state where no magnetic flux is applied to 2.5V, the measurement accuracy can be further improved.
進而,為了將磁石309之磁通量密度的差異去除並更進一步使精確度提升,較理想,係對於當浮標305為位置於最下點處時的磁性感測器310之輸出和前述之0mT時之磁性感測器310之輸出的2點作測定,並進行修正。具體而言,若是求取出2點間之輸出差係相對於作為基準之磁性感測器310之2點間之輸出差而成為何種程度(比例)之水準,並依循於此比例,來對於每次所測定出的磁性感測器310之輸出進行修正,則係能夠更進一步使精確度提升。Furthermore, in order to remove the difference in the magnetic flux density of the
圖7,係為從上側來對於洗劑自動投入單元301之槽托盤302作了觀察的立體圖。由於相對於磁通量密度之變化的磁性感測器310之輸出變化之測定係成為非接觸,因此,在將洗劑槽303從槽托盤302而卸下的清掃時,係並不需要進行電性配線之裝卸等,而能夠減輕使用者之負擔。進而,在非接觸式中,測定面之髒污係會對於測定造成影響,但是,在本實施例中,係設為使洗劑供給時之供水的一部分,通過經由外部投入之洗劑投入部7以及槽托盤302來對於外槽底部進行供水之供水路徑318,並且進而將供水之一部分或者是供給幫浦237及其之周圍配管(未圖示)之剩餘水通過導入口315來從流水路徑316而流動至磁性感測器310之安裝部周邊之構成。藉由此,由於係成為能夠恆常對於槽托盤302之內面進行洗淨之構成,因此,係能夠保持形成磁性感測器310與磁石309所相對向的空隙之內壁的清掃性。通過了通水路徑316後之水,係被供水至外槽2之供水口2a(參考圖2、圖8)處。另外,磁性感測器310,係構成為被配置在洗劑槽之長邊方向中央近旁處,並相對於樞軸308之設置位置而被設置在與洗劑槽之投入門312之洗滌液投入口相反側之位置處。FIG. 7 is a perspective view of the
樞軸部308,係被設置在就算是在填充了規定量之洗劑量時也不會被浸入至液面中的洗劑槽303上部處。具體而言,在本實施例中,係將具備有承受旋轉軸314之軸承部的樞軸部308,設為架橋於槽側面間並固定在側面上部處的構成。因此,假設就算是在將蓋311卸下並想要填充洗劑時,亦由於能夠將浮標305之浮起部306設為收容於槽內之狀態,因此係不會有將洗劑灑到周圍的情形。又,藉由將成為與磁性感測器310相對向之面的浮標305之浮起部306的底面設為在浮標305處而不會作必要以上之對於外部的露出,係能夠使會對於磁通量造成影響的鐵成分等附著於浮起部306之底面處。The
在填充洗劑的情況時,由於係亦能夠一面對於浮標305之浮起部306的沉入容積量作確認一面進行填充,因此就算是在填充後而將蓋311作了關閉時,也不需要擔心洗劑是否會溢出。又,在將蓋311作了卸下時,由於係亦能夠對於洗劑從樞軸部308而滴下的狀況作確認,並且若是為有色的洗劑則亦能夠對於其之濺灑至樞軸部308處的痕跡作確認,因此係亦能夠容易地對於進行擦拭清掃之必要性或洗劑填充量之調整作判斷。In the case of filling lotion, since it can also be filled while confirming the sinking volume of the floating
循環幫浦18之輸出,係成為能夠充分地將與最大洗滌負載相對應的洗滌水一直上汲至設置在外槽2之上方的散水噴嘴223處之規格。因此,若是藉由前述之洗劑溶解工程之循環路徑來使其循環,則循環幫浦18之所需動力最終而言係轉換為熱能,並使高濃度洗劑液之溫度上升。所產生的高濃度洗劑液,在之後之工程中係一直被上汲至設置在外槽2之上方的散水噴嘴223處,並被對於滾筒3內之洗滌物207作散佈。此時,在循環幫浦18之出口處,係成為需要設置一直導引至外槽2上方處之路徑和如同上述一般地並不進行散佈而回到受水部54處之路徑,但是,在本實施例中,係預先在循環幫浦18之殼體外周處,設置與各個的路徑相連之吐出口(參考圖2),並藉由切換循環幫浦18之旋轉方向,來藉由因應於旋轉方向而從最初所通連之吐出口側進行吐出,而對於路徑作切換。或者是,就算是將循環幫浦18之吐出口設為單一場所,並於其之下游側處而使其分歧並對流路作切換,在功能上也不會有任何的問題。The output of the circulating
在前置洗衣工程中,通常在外槽2內,係存在有滲入有洗劑液之洗滌物207,並在外槽2底部之受水部54處存在有少量的洗劑液。若是藉由使滾筒3旋轉,而基於「在將洗滌物207一直舉升至滾筒3上部之後,藉由重力來使其一直落下至底部處」的翻滾動作來持續進行拍打洗衣,則由於滲入至洗滌物207中之洗劑液係被榨出,因此係因應於需要而間歇性地驅動循環幫浦18並再度將洗劑液散佈至洗滌物207處。在此動作中,亦同樣的,若是將洗滌水和洗滌物之所謂的洗淨溫度提升,則係能夠使洗淨性能提升。In the pre-washing process, usually in the
因應於被進行洗滌之行程,對於被散佈有高濃度洗劑液之洗滌物207,而將從送風風扇20而來之氣流在藉由溫風加熱器213來作了加溫之後再作吹附,來一面加溫洗滌物207一面進行洗淨。洗滌物207由於係身為保水有高濃度洗劑液之狀態,因此相較於使空氣佔據洗滌物207之纖維空隙的情形,熱傳導係為佳,而能夠有效率地進行加熱。又,藉由將溫度提昇,係能夠使被保水之高濃度洗劑液的表面張力下降。進而,若是洗滌物207之溫度提升,則由於纖維中之空氣係使纖維膨潤,因此係能夠更為促進高濃度洗劑液之對於纖維的浸透。藉由此,係能夠從纖維而將更多的髒污在短時間內而分離。所分離出的髒污,由於係在被保水之高濃度洗劑液內而迅速地分散,因此係能夠防止其再度凝集並再度附著的情形。In response to the washing process, for the
又,依存於髒污的不同,係會有以當潑灑至洗滌物207處之洗滌水之水量為少(洗劑濃度為濃)的情況時會更良好地去除的情況和相反地當洗滌水之水量為多(洗劑濃度為淡)的情況時會更良好地去除的情況。在作用於兩者的去污之原動力上,係存在有差異,而能夠如同下述一般地來解釋。身為洗劑之主要成分的其中一者之界面活性劑,係促進纖維之浸濕,並進而藉由將髒污和布的表面電位拉至界面活性劑之負極性,而發揮使其帶電為負的作用。藉由此,係有著使從洗滌物所浮起的髒污彼此間和纖維與髒污之間之反作用例增加的效果。因此,在以凡得瓦力作為主體而附著的固態之髒污之洗淨中,若是界面活性劑的濃度越濃,則係越能夠使與凡得瓦力相對抗的前述之反作用力增強。故而,固態髒污等,一般而言係若是界面活性劑濃度越濃則越容易去除。In addition, depending on the difference in dirt, there may be cases where the amount of washing water splashed on the
另一方面,容易溶解於水和洗滌水中之所謂水溶性的髒污,係依存於相對於身為溶媒之洗滌水的成為溶質之髒污之濃度,而溶解速度會有所改變。在髒污之濃度為淡的液中,溶解速度係為大,但是,在濃的液中,溶解速度係會降低。因此,若是預先將分散於洗滌物207所保水的洗滌水中之髒污的濃度稀釋,則髒污係更加容易從洗滌物207而去除。換言之,係成為需要將洗滌物207所保水之洗滌水置換為髒污濃度為極低之洗滌水,或者是進行將髒污之濃度稀釋的處置。亦即是,針對此種髒污的界面活性劑之功用,由於係以將從洗滌物207所剝落的髒污作分散保持並防止凝集或再附著的功用為較重要,因此,只要滿足某種程度的洗劑濃度,則相對於髒污之去除的洗劑濃度之依存性係為小。On the other hand, the so-called water-soluble dirt, which is easily dissolved in water and washing water, depends on the concentration of the dirt that becomes a solute relative to the washing water, which is a solvent, and the dissolution rate varies. In a liquid with a light concentration of dirt, the dissolution rate is higher, but in a thick liquid, the dissolution rate will decrease. Therefore, if the concentration of the dirt dispersed in the washing water contained in the
又,不論是針對何者的髒污,將洗淨溫度提升一事結果性而言均會對於使洗淨力增加一事有所助益。針對前者,藉由將溫度提升,由於洗滌水中之分子擴散係被促進,因此係能夠使更多的界面活性劑附著在布表面或髒污表面上,而能夠使反作用力增強。針對後者,亦同樣的,在洗劑溶液中之界面活性劑的擴散係提升,而能夠促進布表面之浸濕。進而,係亦能夠使分離了的髒污有效地擴散。Moreover, no matter what kind of contamination it is, raising the cleaning temperature will result in an increase in the cleaning power. For the former, by increasing the temperature, the molecular diffusion in the washing water is promoted, so more surfactant can be attached to the cloth surface or the dirty surface, and the reaction force can be enhanced. Regarding the latter, it is also the same that the diffusion system of the surfactant in the lotion solution is improved, which can promote the wetting of the cloth surface. Furthermore, the system can also effectively diffuse the separated dirt.
又,係亦可另外設置相較於循環幫浦18而更為小流量之循環幫浦(未圖示),並藉由從受水部54而上汲並在送風風扇20之出口近旁處而散佈於溫風中,來使液滴混合於溫風中並散佈至洗滌物207處。在洗滌工程之途中,若是一直追加供水至能夠確保有通常之循環量水準為止,並藉由循環幫浦18來進行散佈,則洗滌物207之溫度係會急遽地降低,但是,若是設為此種構成,並將少量的循環水追加至溫風中而進行散佈,則由於係能夠將包含於洗滌物207中之水全面性地且僅些許地進行交換,因此,係亦能夠抑制洗滌物207之急遽的溫度降低,故而,係能夠使洗淨性能更進一步提升。In addition, a circulating pump (not shown) with a smaller flow rate than the circulating
在之後的正式洗衣工程中,係在前置洗衣工程結束了的時間點處進行追加供水,而將受水部54之水量增加,並使水位上升。此水位,係設為對於藉由循環幫浦18來從受水部54而將洗滌水上汲並從外槽上部之散水噴嘴223而連續散佈一事而言為充分的水位。根據負載或水硬度所算出的投入洗劑量,係亦可分開至前述洗劑溶解工程和正式洗衣工程中而進行投入。例如,針對在洗淨上而言相較於洗劑濃度係以洗淨溫度為更加有效的髒污,較理想,係進行「藉由在較少的洗滌水量時有效率地提升水溫並將髒污去除,之後進行相對於規定量之剩餘的洗劑之投入與水的追加來雖然會使水溫相較於前半而變得更低但是洗劑濃度會相較於前半而更為提升,而將洗劑濃度之影響為大的髒污重點性地去除」之運轉。In the subsequent formal laundry project, additional water supply is performed at the time point when the pre-washing project ends, and the water volume of the
又,係亦可設置將在全部洗滌工程中所被分割投入的累積之洗劑投入量較規定量而更為增加並全體性地將洗劑濃度作了提高的特別行程。從散水噴嘴223而來之散佈,係可為連續,亦可為間歇性。具體而言,當在洗滌物207之裡側等處仍附著有多數之髒污的期間中,藉由以連續來進行散佈並促進洗滌水之攪拌,係能夠將洗滌物207所保水的洗滌水恆常交換為髒污濃度為低之洗滌水。之後,在髒污幾乎均被去除之後,係以將拍打洗衣之機械力作為主體而將剩餘之髒污去除的洗淨效率為更佳。故而,後半之散佈,係以不會對於機械力造成妨礙的方式來設為間歇性散佈為理想。In addition, it is also possible to provide a special course that increases the amount of the accumulated lotion input divided and injected in all the washing processes more than the prescribed amount and increases the concentration of the lotion as a whole. The dispersion from the
又,藉由將循環幫浦18之驅動力設為間歇性,由於係能夠抑制消耗電力量,因此從省能源的觀點來看亦為理想。另外,散水噴嘴223,係在外槽2處,被固定於當從洗衣烘乾機正面作觀察時較能夠旋轉之滾筒3之中心軸而更上側處並且當從洗衣烘乾機側面作觀察時為靠向正面的前側之位置處,而設為將從散水噴嘴223而來之噴出範圍相對於滾筒3之半徑方向而設為廣角並作散佈的構造。在此正式洗衣工程中,係藉由進行廣範圍之散佈並且藉由滾筒3之旋轉來將積存於滾筒3內之下方處的洗滌物207舉升,再使其從滾筒3內之上方而落下,來對於洗滌物207賦予機械性之力,而進行拍打洗衣。若是滾筒之直徑越大,則越能夠得到廣範圍之散佈和拍打洗衣之相輔相成之效果,而能夠縮短正式洗衣工程之時間。在此工程中,本質性而言,在為了將洗滌物以及洗滌水之洗淨溫度提升而如同前置洗衣工程一般地使用溫風一事上,亦並無不同。溫風吹出噴嘴203和散水噴嘴223,在從正面來對於洗衣烘乾機作觀察時,係設為相對於中心軸而相對的配置。係成為就算是起因於將滾筒3內之水位提升而相對於相同旋轉數之旋轉幫浦的循環水量增加,亦對於由溫風所致之水滴的伴隨和與水流之間之直接接觸所導致的發泡作抑制之構成。In addition, by making the driving force of the circulating
又,在本實施例中,正式洗衣工程,係實行第1正式洗衣工程和在第1正式洗衣工程之後所實行的第2正式洗衣工程。在第1正式洗衣工程之結束時所供水的第2正式洗衣工程之水量,係設為較第1正式洗衣工程之水量而更多,第2正式洗衣工程之循環幫浦18之循環流量,係設為較在第1正式洗衣工程中之循環幫浦18之循環流量而更大。進而,第2正式洗衣工程之滾筒驅動的馬達M10a之旋轉速度,係設為較第1正式洗衣工程之馬達M10a之旋轉速度而更低。In addition, in this embodiment, the formal washing process refers to the first formal washing process and the second formal washing process performed after the first formal washing process. At the end of the first official laundry project, the amount of water supplied to the second official laundry project is set to be more than that of the first official laundry project. The circulating flow of the circulating
正式洗衣工程,主要係為了將在水量為少之前置洗衣工程中難以洗到的衣物之內側或口袋之中等的髒污從洗滌物207而分離,而進行之。因此,為了將各種的髒污去除,更理想,係設為如同前述一般地對於水量和滾筒驅動之馬達M10a之旋轉速度作了改變之至少2個以上的工程之組合。在第1正式洗衣工程中,由於係將滾筒3之旋轉速度提高,因此,與滾筒3之旋轉一同地而被舉升至上方之洗滌物207,係並不會全部落下至下方,其之大半係起因於離心力而在貼在滾筒3之內壁上的狀態下與滾筒3一同旋轉。由於係於該處而從循環幫浦18散佈洗滌水,因此,係將對於洗滌物207之洗滌水的貫通流速增快。藉由此,來成為使髒污容易從洗滌物207溶出。The formal laundry process is mainly performed to separate the dirt from the
在接續於此之第2正式洗衣工程中,係將滾筒3之旋轉速度設為較第1正式洗衣工程而更低,而將離心力減弱並極力抑制洗滌物207之對於滾筒3的貼附,來設為對於從滾筒3之上方來打落至下方的拍打洗衣有所重視之工程。藉由此,藉由使機械力作用於洗滌物207處,係能夠主要使疏水性之髒污成為容易去除。在將洗滌物207從滾筒3之上方來打落至下方時,藉由將停留於滾筒3之下方處的洗滌水之水位增高並且亦將循環水量增多,係亦能夠防止洗滌物207彼此發生必要以上之直接性碰撞並使纖維被壓迫的情形。In the second formal washing process following this, the rotation speed of the
如同上述一般,在本實施例中之第1正式洗衣工程和第2正式洗衣工程之組合,係設為對於洗滌物207之黑點、硬化作抑制的運轉方式,以下,以其之機制作為中心來進行說明。在第1正式洗衣工程之後,係進行第2正式洗衣工程,但是,第2正式洗衣工程之水位WL2,係成為較第1正式洗衣工程之水位WL1而更高(WL1<WL2)。亦即是,藉由將外槽2內之洗淨水的水量增加,係能夠使從洗滌物207所剝落了的髒污分散於洗淨水中,而能夠對起因於從洗滌物207所剝落的髒污再度附著於洗滌物207處一事所造成的「洗滌物之黑點」作抑制。As mentioned above, in this embodiment, the combination of the first formal washing process and the second formal washing process is set as an operation mode that suppresses the black spots and hardening of the
又,第2正式洗衣工程之滾筒3的旋轉速度DR2,係設為較第1正式洗衣工程之滾筒3的旋轉速度DR1而更慢(DR1>DR2)。藉由將滾筒3之旋轉速度DR2設為較旋轉速度DR1而更慢,在藉由滾筒3之旋轉來將積存於滾筒內之下方處的洗滌物207舉升並從滾筒3內之上方而落下時,開始落下的位置係變低。亦即是,對於被進行拍打洗衣之洗滌物207所施加的落下衝擊(機械力)係被作抑制,而能夠對於「洗滌物之硬化」作抑制。In addition, the rotation speed DR2 of the
又,藉由將水位WL2提高,亦同樣的,落下衝擊(機械力)係被作抑制,而能夠對於「洗滌物之硬化」作抑制。另一方面,滾筒3之旋轉速度DR1,就算是以較使起因於離心力而貼附在滾筒3之內壁上的洗滌物207在直到被舉升至上方處為止的期間中會起因於重力而全部剝落並落下而更快的旋轉速度來進行旋轉(離心力>重力),而構成為對於全部的洗滌物而並不使該些進行如同拍打洗衣一般之落下的運轉,也不會造成問題。亦即是,係亦可設為藉由極力抑制拍打洗衣並使較通常之洗滌運轉而更多的循環量通過洗滌物207來進行洗淨的運轉。In addition, by increasing the water level WL2, the impact of falling (mechanical force) is also suppressed, and the "hardening of the laundry" can be suppressed. On the other hand, the rotation speed DR1 of the
然而,雖然會有使由拍打洗衣所致之洗淨性能降低之虞,但是,相對於此,藉由將第2正式洗衣工程之循環幫浦18的流量PF2設為較第1正式洗衣工程之循環幫浦18的流量PF1而更大(PF1<PF2),係能夠確保由水流所致之洗淨性能。例如,循環幫浦18之循環流量,係以設為30L/min以上80L/min以下為理想。又,第1正式洗衣工程之運轉時間(T1)和第2正式洗衣工程之運轉時間(T2),較理想,係以會使第2正式洗衣工程之運轉時間(T2)成為較第1正式洗衣工程之運轉時間(T1)而更長的方式,來作設定(T1<T2)。藉由設為此種構成,係能夠更進一步對於「洗滌物之硬化」作抑制。However, although there is a risk of lowering the washing performance caused by flapping washing, on the other hand, by setting the flow rate PF2 of the
又,在正式洗衣工程之控制中,主要係使用濁度判定部117和臨限值記憶部118,來如同以下一般地進行控制。於此,濁度判定部117,係具備有基於電導度測定部115所測定出的電導度等來判定衣物之髒污程度(以下,稱作濁度)的功能。臨限值記憶部118,係具備有記憶濁度判定部117在對於衣物之髒污程度(濁度)進行判定時所使用的臨限值之功能。在第1正式洗衣工程之前後,藉由電導度測定部115,來對於洗淨水之電導度EC1作計測。另外,在對於電導度作計測時,較理想,係使由供水電磁閥16所致之對於外槽2之供水、由循環幫浦18所致之循環、由馬達M10a所致之滾筒3的旋轉停止。In addition, in the control of the actual washing process, the
在濁度判定部117處,係判定在第1正式洗衣工程之前後所測定出的電導度EC1之差是否為被記憶在臨限值記憶部118中之臨限值以上。若是為否(較臨限值而更低),則係判斷為髒污為少,若是為是,則係判斷為髒污為多,並前進至之後的第2正式洗衣工程。The
第2正式洗衣工程,係設為如同前述一般的將水位設為較第1正式洗衣工程而更高並進而亦將循環幫浦18之循環流量增多的拍打洗衣。亦即是,係對於在洗滌物207被舉升至滾筒3之上方並被打落至下方處時,洗滌物207彼此相互碰撞並對纖維造成壓迫的情形作防止。然而,若是此工程越長,則洗滌物207之硬化係會有越增大的傾向。故而,在髒污為較少的情況時,係希望將第2正式洗衣工程盡量縮短。因此,在能夠判斷為髒污為少的情況時,係將第2正式洗衣工程之運轉時間調整為短。另外,濁度之判定,係亦能夠在其他之工程間之切換時序或各工程的運轉時間之重新評估中作使用。The second formal washing process is set as the above-mentioned general water level to be higher than the first formal washing process, and furthermore, the circulation flow of the circulating
在洗清工程中,係開啟排水閥V1,而將洗滌水排水,之後,將排水閥V1關閉,並將洗清水對於外槽2內進行供水直到成為特定之水位為止。若是被設定有柔軟劑之自動投入,則係在洗清工程之中之最後的洗清工程中,與洗劑自動投入同樣地而進行投入。被供水至手動柔軟劑投入部以及槽托盤處之水,係在使從洗劑自動投入單元301而來之柔軟劑被作了混入之後,被導引至位置於滾筒3底部處之受水部54處。之後,使滾筒3旋轉,而將洗滌物207和洗清水作攪拌而進行洗清。In the washing process, the drain valve V1 is opened to drain the washing water, and then the drain valve V1 is closed, and the washing water is supplied to the
在自動投入後,係針對洗劑以及柔軟劑之雙方而均進行剩餘量偵測。作為時序,係在不會出現有對於磁性感測器310之電性雜訊以及伴隨著液面之震動所導致之浮標305之浮起部306之變動或者是能夠進行修正的程度之時序處而進行。After the automatic injection, the remaining amount is detected for both the lotion and the softener. As the timing, it is at a timing where there is no electrical noise to the
針對在洗滌工程以及洗清工程時之供水和在工程內之洗滌水與洗清水之電導度測定中所使用的供水路徑50以及電導度檢測手段4作說明。圖8,係為對於外槽2而從本體正面側來作了觀察的立體圖。外槽2,係具備有外周壁51和底壁52。在外槽2之底壁52的背面53(內面)處,係被形成有用以將包含有水、洗劑、漂白劑等之液體從供水口2a來導引至外槽2之下方部分處的供水路徑50(溝55)。於此,從外周壁51起而一直到底壁52處的圓筒形狀之外周壁51之內徑會逐漸減少的連結部分,係設為被包含在底壁52中。The
供水路徑50,係為將被供給至外槽2之上部處的水,以流動至被形成於外槽2之內底部處的受水部54處的方式來作導引之路徑。此供水路徑50,例如,係具備有被形成於外槽2之上部處並對於外槽2內供給液體之供水口2a、和被形成於外槽2之底壁52處並用以將液體從供水口2a來導引至外槽2之下方部分處的溝55、以及將溝55之下端部以外作覆蓋並形成管路的覆蓋構件61,而構成之。另外,覆蓋構件61,係亦可並不作設置。The
溝55,係由從供水口2a起而朝向鉛直方向下方延伸,並朝向外槽2之下方部分而被形成為平緩地作了彎曲的略圓弧形狀之流路(供水路徑50)而成。溝55,係在縱剖面觀察下被形成為ㄈ字狀,從供水口2a所對於外槽2內之供水,係在矩形剖面之深處側角隅部附近流動,而不會有從溝55內而擴散至外槽2內的情形。The
覆蓋構件61,係為對應於溝55之形狀而在平面上作了彎曲的帶狀板體,作為覆蓋構件61之材質,例如係與外槽2相同地而使用有PP(聚丙烯)。在外槽2之溝55的兩側部處,係被形成有較背面53而更朝向後方作了退避的階差部(省略圖示),藉由在此階差部(省略圖示)上被配置有覆蓋構件61,覆蓋構件61之上面(前面)係成為並不會較背面53而更朝向前方突出。覆蓋構件61,係於被設置在其之帶狀板體之兩側部的複數場所處之孔處,藉由螺絲構件(省略圖示)等而被固定在外槽2處,並被形成有供水路徑50之管路。The covering
電導度檢測手段4,係被設置在從供水口2a所供給而來之水最初會觸碰到的位置處。亦即是,係被設置在從供水口2a所供給而來之水會從溝55而流下至受水部54處的位置處。因此,電導度檢測手段4,在自來水被作供水的情況時,係能夠對於水的電導度正確地進行測定。在被供給有洗劑或柔軟劑的情況時,亦同樣的,電導度檢測手段4,係能夠將在水之中為包含有洗劑或柔軟劑一事偵測出來。又,電導度檢測手段4,由於係被配置在受水部54之內部,因此,在前述之洗劑溶解工程中,係成為能夠檢測出溶解有洗劑之水的電導度。The conductivity detection means 4 is installed at a position where the water supplied from the
又,電導度檢測手段4,係為檢測出洗滌前之自來水、洗滌運轉(洗衣、洗清、脫水)時之洗滌水之電導度的感測器,並成為在合成樹脂製之感測器基底處具備有一對的電極(未圖示)之構成。電極,例如藉由設為平板形狀,係能夠相較於棒狀之電極而確保有更廣的電極面積,並成為能夠進行安定的電導度之偵測。若是使用有電導度檢測手段4,則由於係能夠判定洗滌水或洗清水內之洗劑或柔軟劑之有無,因此,係亦能夠兼用來進行由洗劑自動投入單元301所致之洗劑或柔軟劑的投入程度之確認。In addition, the conductivity detection means 4 is a sensor that detects the conductivity of the tap water before washing and the washing water during the washing operation (washing, washing, dehydration), and is a sensor base made of synthetic resin It is equipped with a pair of electrodes (not shown). The electrode, for example, by being in the shape of a flat plate, can ensure a wider electrode area than a rod-shaped electrode, and can be used for stable conductivity detection. If the conductivity detection means 4 is used, since it can determine the presence or absence of lotion or softener in the washing water or washing water, it can also be used to perform the lotion or softener caused by the automatic
具體而言,係對於由根據供給幫浦237之驅動時間所估計出的洗劑量所致之洗淨水濃度和藉由電導度檢測手段4所檢測出的濃度是否相符一事進行監視,並預先作記憶。例如,若是持續了複數次的在存在有大幅度差異下之運轉,則係判斷從洗劑自動投入單元301而來之洗劑供給係並非為良好,並對於使用者作報告。Specifically, it monitors whether the concentration of the washing water caused by the amount of detergent estimated based on the driving time of the
在脫水工程中,係開啟排水閥V1,而將外槽2內之洗清水排水,之後,使滾筒3旋轉並對於洗滌物207進行離心脫水。脫水旋轉數,只要是不會發生無法取得洗滌物207之平衡而馬達M10a之電流值超過上限等的問題,則係使其一直上升至與負載相對應之設定旋轉數。就算是脫水之水的一部分被上捲至送風管路29側處,亦由於在將外槽20之背面部與送風管路29之下部作連結的蛇腹軟管215以及外槽側安裝部18處,係附加有從送風管路29起朝向外槽20背面部而下降之傾斜,因此係能夠迅速地回到外槽側處。若是將脫水旋轉數提升而滾筒3進行高速旋轉,則震動係亦會傳導至外槽20處,外槽20自身亦會作些許之震動。In the dehydration process, the drain valve V1 is opened to drain the washing water in the
由於送風管路29係被固定於框體1處,因此,將外槽20之背面部與送風管路29之下部作連結的蛇腹軟管215係連動並將震動之一部分作吸收。進而,伴隨著旋轉滾筒3之高速旋轉,震動係亦會傳導至門9側,但是,藉由風扇出口管路之橡膠製之蛇腹管212,係能夠將對於送風風扇20之震動作吸收並防止其之傳播。Since the
在烘乾工程之前半,係如同圖2中所示一般,將由送風風扇20所致之藉由絕熱壓縮所作了升溫的空氣對於旋轉滾筒3內吹出並通過噴嘴部203來送風,而使其與洗滌物207進行熱交換,並且使水分從洗滌物207而蒸發。包含有蒸發後之水分的成為高濕度之空氣,係通過送風管路29而被導引至送風風扇20之吸入口處,並在再度作了升壓之後,對於旋轉滾筒3內送風。吸氣閥204,係形成送風管路29之壁面的一部分,並設為將送風管路29之內與外作了隔離的全閉狀態。旋轉滾筒3出口之高濕度之空氣,在通過外槽2以及送風管路29時,若是與外槽2以及送風管路29進行熱交換並成為露點溫度以下,則係使與飽和蒸汽壓的下降相對應之量的水分在外槽2以及送風管路29之壁面處凝結。在送風管路29處而凝結了的水分,最終係會從送風管路29之下部起而積存於蛇腹軟管215中,但是,由於係附加有從送風管路29起朝向外槽20背面部而下降之傾斜,因此係亦能夠將凝結水經由外槽2來一直移送至排水口39附近處。在想要增加凝結量而謀求烘乾時間之縮短的情況時,就算是在送風管路29內之上部處設置冷卻水散水部(未圖示),並對於送風管路29內進行散水而將空氣強制性地冷卻至露點以下並進行除濕,也不會有任何的問題(水冷除濕方式之併用)。In the first half of the drying process, as shown in Fig. 2, the air heated by the adiabatic compression caused by the
在烘乾工程之後半,係將吸氣閥204以及排水閥V1開啟。於圖2中,係對於在烘乾工程之後半的洗衣烘乾機內之空氣之流動作展示。將位於送風風扇20之吸入側處的吸氣閥204,以朝向送風管路29之內側(風路內)而彎折的方式來開啟。開度θ,相對於以將送風管路29之風路大略(忽略漏洩程度)閉塞的方式來作了開啟的全開狀態θT,在本實施例中係作略一半的打開(0<θ<θT)。從吸氣閥24來將送風管路29外之框體內空氣吸入,並與循環空氣之一部分作混合,而對於旋轉滾筒3內送風。被從旋轉滾筒3所推出的空氣,係藉由排水孔來通過排水軟管而被排出至排水口21處。在一般性之排水阱202的情況時,由於水封高度係為50~80mm程度,因此,在此工程之初始時,係將排氣閥204設為全開,並提升滾筒內壓力,而預先破除水封。為了破除水封,由於排水軟管26側之壓力係成為需要約1000Pa以上,因此,較理想,係適度地提升送風風扇20之旋轉數而進行升壓。又,隨著烘乾之進展,會產生凝結水,並逐漸積存於排水阱202處。因此,係空出有一定之間隔地而進行前述之破除水封的動作。In the second half of the drying process, the
從旋轉滾筒3而來之排氣,係通過從排水孔起而至排水閥V1之連接軟管、和溢流軟管205,來進行排氣。另一方面,主要為從框體底部而被導入至框體內之吸氣,在直到位於框體上部之吸氣閥204為止之間,由於係通過旋轉滾筒驅動用馬達M10和風扇馬達214之周圍,因此,係成為高溫,並從吸氣閥204而被導入至送風管路29內。故而,通常,係並不需要對於設置在送風風扇20之出口處的溫風加熱器213進行通電。在從旋轉滾筒3起通過溢流軟管205而從排水閥V1所排氣的排氣路徑內,係包含有外槽2背面部之外槽側安裝部和蛇腹軟管215,但是,從外槽2背面部起而相對於送風管路29係成為上升傾斜,排氣之對於送風管路29的流入角度係成為較90度而更大之鈍角,而能夠減少排氣路徑之風路損失。The exhaust from the
烘乾判定,係在從烘乾開始時或者是從某一運轉之開始起的規定時間中,藉由排水溫度感測器T1來對於外槽下部排水口溫度T1a進行測定,並藉由外部氣體溫度感測器T4來對於外部氣體溫度T4a進行測定(初期溫度之設定)。之後,在經過了與負載相對應之規定時間之後,對於用以進行結束判定之外槽下部排水口溫度T1b和外部氣體溫度T4b進行測定,並求取出各個的初期溫度與結束判定溫度之間之差(ΔT1=T1a-T1b、ΔT2=T2a-T2b),並進而確認該些之溫度差(ΔT1-ΔT2)是否為規定溫度以上,而對於烘乾結束進行判定。The drying judgment is determined by measuring the temperature T1a of the drain outlet in the lower part of the outer tank by the drain temperature sensor T1 at the beginning of the drying or within a predetermined time from the start of a certain operation, and by external air The temperature sensor T4 measures the outside air temperature T4a (setting of the initial temperature). After that, after a predetermined time corresponding to the load has elapsed, the temperature T1b and the outside air temperature T4b at the bottom of the tank for the end judgment are measured, and the difference between the initial temperature and the end judgment temperature is obtained. Difference (ΔT1=T1a-T1b, ΔT2=T2a-T2b), and then confirm whether the temperature difference (ΔT1-ΔT2) is above a predetermined temperature, and judge the end of drying.
在烘乾結束後,係一面相較於排水口21側之壓力而將排水軟管26側之壓力保持為高,一面將送風風扇20之旋轉數一直下降至不會破除水封之壓力水準,並開啟供水電磁閥(未圖示)而使水流動,來使排水阱202之水封恢復,並成為結束烘乾工程。After drying, the pressure on the side of the
如此這般,在烘乾結束後,藉由一面將排水軟管26側之壓力保持為特定以上一面經由排水軟管26來對於排水孔供給水,係能夠對於從排水孔而來之臭氣作抑制,並且能夠使排水阱202之水封恢復。另外,此排水阱202之恢復,只要是將排水軟管26側之壓力保持為高,則不論是在(排水軟管排氣之)烘乾運轉之最後或者是烘乾運轉之結束後的何者均可。In this way, after drying, the pressure on the side of the
在本實施例之洗滌烘乾運轉中的剩餘量偵測之時序,基本上,係以能夠確實地避免起因於框體之震動所導致的液面變動和起因於構成機器之動作所導致的電性雜訊之干擾之「緊接於主電源之投入之後」為理想。在此時間點處,若是不存在有剩餘量,則係進行報告。因應於需要,在洗劑或柔軟劑之投入後的並無對於構成機器之電源投入或者是不會對於剩餘量偵測造成影響的時序處,進行剩餘量有無之判定。在緊接於洗滌運轉之後,係進行剩餘量之確認,若是不存在有剩餘量,則係在此時間點處進行報告。進而,在洗滌烘乾運轉的情況時,較理想,係亦在烘乾結束時間點(洗滌烘乾運轉結束後)對於剩餘量作確認,若是不存在有剩餘量,則進行報告。The timing of the remaining amount detection in the washing and drying operation of this embodiment is basically to be able to reliably avoid the liquid level fluctuation caused by the vibration of the frame and the electricity caused by the action of the composing machine. "Immediately after the main power is turned on" for the interference of sexual noise is ideal. At this point in time, if there is no remaining amount, a report is made. In response to needs, after the lotion or softener is put in, there is no influence on the power supply of the machine or the remaining amount detection is not affected, and the remaining amount is judged. Immediately after the washing operation, the remaining amount is confirmed. If there is no remaining amount, the report is made at this point in time. Furthermore, in the case of the washing and drying operation, it is preferable to confirm the remaining amount at the end of the drying time (after the end of the washing and drying operation), and report if there is no remaining amount.
圖9,係為對於在本發明中所使用的洗劑槽303之變形例作展示之剖面圖。在本實施例中,係成為相對於浮標305而將3個的磁性感測器310在槽之高度方向上有所偏移地而作配置之構成。具體而言,浮標305,由於係相對於旋轉軸314,而經由一定長度之臂307來以描繪出圓弧的方式而移動,因此,係在槽內部設置沿著圓弧的軌道之凹部,並在凹部之外面處,將高度作改變地而設置磁性感測器310。藉由設為此種構成,因應於浮標305之高度的變化,由於各個的磁性感測器310之輸出係會改變,因此,係能夠以更廣的幅度來偵測出槽內液量。又,在本實施例中,雖係將磁性感測器之數量設為3個,但是,由於係因應於槽之形狀或浮標305之浮起部306之可動範圍來作設置,因此在數量上係並不被作限制。FIG. 9 is a cross-sectional view showing a modification of the
