1、精選優(yōu)質(zhì)文檔-傾情為你奉上洗衣機(jī)設(shè)計(jì)方案作者：Peter J. Biermayer單位：勞倫斯伯克利國(guó)家實(shí)驗(yàn)室能源和環(huán)境部門地址：加利福尼亞州承辦單位：美國(guó)能源部規(guī)范和標(biāo)準(zhǔn)辦公室本文根據(jù)合同號(hào)DE-AC03-76SF00098，由美國(guó)能源部規(guī)范和標(biāo)準(zhǔn)辦公室，國(guó)家和社區(qū)項(xiàng)目，建筑技術(shù)辦公室，能源效率和可再生能源的助理秘書長(zhǎng)支持。洗衣機(jī)設(shè)計(jì)方案1. 引言本報(bào)告討論了提高標(biāo)準(zhǔn)容量的家用洗衣機(jī)的能源效率的可行的設(shè)計(jì)方案。在本設(shè)計(jì)方案分析中所使用的程序是基于由能源部（DOE）解釋的規(guī)定，該規(guī)定概述了工藝改進(jìn)措施。根據(jù)合理的規(guī)則，不同的電器排名后，確定了潛在的設(shè)計(jì)方案，這在電器效率標(biāo)準(zhǔn)頒布的過(guò)程中又進(jìn)了一

2、步。然后用篩選因子來(lái)確定是否應(yīng)進(jìn)一步考慮排除某一設(shè)計(jì)方案。篩選設(shè)計(jì)方案中使用的很多輸入程序都是由洗衣機(jī)制造商提供。其他來(lái)源于貿(mào)易刊物和家用電器制造商協(xié)會(huì)（AHAM）。雖然（在新工藝中）現(xiàn)有分析的設(shè)計(jì)方案階段在規(guī)章制定預(yù)告（ANOPR）之前，與原ANOPR2相對(duì)應(yīng)，但是以前從廠家收集到的數(shù)據(jù)，現(xiàn)有的AHAM的輸入和其他利益相關(guān)者在這份報(bào)告中仍然會(huì)被考慮。美國(guó)能源部打算在未來(lái)發(fā)出補(bǔ)充的法規(guī)制定提案預(yù)告。2. 產(chǎn)品分類對(duì)消費(fèi)者有使用價(jià)值的家電被納入產(chǎn)品類的分析的行列。類別是家電類型的一個(gè)子集，例如，洗衣機(jī)是一種家電，但是緊湊型洗衣機(jī)就是一種產(chǎn)品類別，家電產(chǎn)品根據(jù)不同的能源利用率被分成不同的類型。能源

3、部劃分類別根據(jù)產(chǎn)品的容量或其他相關(guān)的性能特點(diǎn)，如產(chǎn)品的實(shí)用性和工作效率。一般情況下，類的定義是通過(guò)從家電制造商，貿(mào)易協(xié)會(huì)和其他的相關(guān)的會(huì)議研討中搜集的數(shù)據(jù)來(lái)做出劃分。那些已被指定的沒有通過(guò)能源部測(cè)試程序的類的不再進(jìn)一步分析。目前，洗衣機(jī)的分類如表1所示，其中相應(yīng)的最低能源能效要求自1994年5月14日起生效3。表1 當(dāng)前產(chǎn)品分類和效率標(biāo)準(zhǔn)產(chǎn)品分類效率標(biāo)準(zhǔn)緊湊頂級(jí)加載標(biāo)準(zhǔn)頂級(jí)加載半自動(dòng)頂級(jí)加載前裝加載肥皂水儲(chǔ)蓄EF>=0.90ft/（千瓦時(shí)/圈）EF>=ft3/（千瓦時(shí)/圈）無(wú)沖洗加熱無(wú)沖洗加熱無(wú)沖洗加熱在以前的規(guī)章制定中，頂級(jí)加載和前端轉(zhuǎn)載分別被用來(lái)指垂直和水平軸洗衣機(jī)。因?yàn)樗捷S

4、機(jī)器可以生產(chǎn)成頂級(jí)加載裝置。產(chǎn)品的等級(jí)差別是基于衣服如何被加載而不是如何制作。因此，垂直和水平軸洗衣機(jī)成了制造商的設(shè)計(jì)策略從而實(shí)現(xiàn)獲得不同效率水平的洗衣機(jī)。按照目前的分析，產(chǎn)品可按照表2分類：表2 定義產(chǎn)品分類產(chǎn)品分類定義緊湊型容量小于1.6ft3標(biāo)準(zhǔn)性容量大于1.6ft3在這份報(bào)告中，由于沒有關(guān)于緊湊型產(chǎn)品的可以使用的數(shù)據(jù)，所以只對(duì)標(biāo)準(zhǔn)型產(chǎn)品進(jìn)行了討論。3設(shè)計(jì)方案在洗衣機(jī)的設(shè)計(jì)中設(shè)計(jì)方案的改變將會(huì)使洗衣機(jī)節(jié)能，美國(guó)能源部在1994年11月14日發(fā)布了能源法制規(guī)，要求設(shè)計(jì)方案要提高洗衣機(jī)的效率。基于這些設(shè)計(jì)方案美國(guó)家庭制造商協(xié)會(huì)對(duì)洗衣機(jī)使用范圍的分布進(jìn)行了調(diào)查。問(wèn)卷對(duì)能源的利用率和設(shè)計(jì)方案的成

5、本進(jìn)行了數(shù)據(jù)的要求，最初的問(wèn)卷發(fā)出之后，美國(guó)能源部與制造商對(duì)于能源的法制法規(guī)進(jìn)行了研討，研討結(jié)果表明，那些最初的設(shè)計(jì)選項(xiàng)列表的修改和補(bǔ)充都是家庭制造商與美國(guó)能源部相互作用的結(jié)果。一些最初的能源設(shè)計(jì)方案被重新命名，以更好的確定自己的技術(shù)。微處理器控制，模糊邏輯更名為先進(jìn)控制傳感器。配置/洗衣桶內(nèi)部和外部的耐受性有了更嚴(yán)格的要求。更高的自旋速度被重新定義為改善水萃取和分離的四個(gè)階段以達(dá)到剩余水分含量的標(biāo)準(zhǔn)，50%，40%，35%和30%。四個(gè)設(shè)計(jì)方案的剩余含水量都相同，但是最終的含水量不同。對(duì)成本和能源利用率的不同的要求以達(dá)到不同層次的剩余含水量的標(biāo)準(zhǔn)。幾個(gè)設(shè)計(jì)方案被分成兩個(gè)或更多的選擇。改進(jìn)的填

6、充控制根據(jù)個(gè)別制造商原本有不同的解釋(在成本和能源節(jié)約上有很大的不同)因此被分成兩種設(shè)計(jì)方案：改善填料的控制和自動(dòng)填充控制。橫軸設(shè)計(jì)選項(xiàng)被分成兩種設(shè)計(jì)方案：橫軸與再循環(huán)橫軸。1)技術(shù)可行性。技術(shù)公司的商業(yè)產(chǎn)品或在工作樣機(jī)將被視為技術(shù)上可行。2)制造的可實(shí)行性安裝并且服務(wù)。如果在商品、可靠設(shè)施和技術(shù)的服務(wù)的技術(shù)的大量生產(chǎn)能在有效日期的標(biāo)準(zhǔn)的時(shí)間內(nèi)來(lái)服務(wù)相關(guān)的市場(chǎng)規(guī)模可以實(shí)現(xiàn)的話，那么這項(xiàng)技術(shù)將被認(rèn)為可實(shí)行制造，安裝和服務(wù)。3）對(duì)產(chǎn)品效用或產(chǎn)品可用性無(wú)不良影響。4）對(duì)健康或安全無(wú)不良影響。消除設(shè)計(jì)選項(xiàng)的原因被展現(xiàn)(或保持進(jìn)一步審議)中討論了個(gè)人的設(shè)計(jì)選項(xiàng)說(shuō)明如下所述。不消除在這份報(bào)告中建議的設(shè)計(jì)方

7、案將在以后的報(bào)告進(jìn)一步分析。在這份最新的報(bào)告中,效率和成本的組合設(shè)計(jì)選項(xiàng)和設(shè)計(jì)選項(xiàng)的組成將進(jìn)行分析。包括在討論的設(shè)計(jì)選項(xiàng)限制性能因素（如果相同的因素由兩個(gè)或更多的廠商提交）。這些限制的性能因素描述受設(shè)計(jì)選項(xiàng)的參數(shù)。通常，這些因素影響的衣服洗漿機(jī)的實(shí)用程序。限制的性能因素不一定從進(jìn)一步分析排除設(shè)計(jì)選項(xiàng)，但描述受設(shè)計(jì)選項(xiàng)和應(yīng)考慮的性能因素。基準(zhǔn)模型一個(gè)洗衣機(jī)基準(zhǔn)模型是用作一個(gè)參考,用于評(píng)估該節(jié)能潛力和各種設(shè)計(jì)選項(xiàng)的增加制造成本。潛在的能源儲(chǔ)蓄是基于一個(gè)擬議的今后經(jīng)營(yíng)實(shí)體檢測(cè)程序(附錄1)。此測(cè)試標(biāo)準(zhǔn)只有一個(gè)新洗衣機(jī)標(biāo)準(zhǔn)頒布時(shí)才會(huì)生效。基線只是代表了典型的垂直軸洗衣機(jī)達(dá)到能源效率允許的最低值，按照指

8、定的全國(guó)家電能源保護(hù)法。目前，所有標(biāo)準(zhǔn)尺寸的洗衣機(jī)必須達(dá)到能源最低允許值1.18伏特的三次方每千瓦時(shí)，根據(jù)現(xiàn)行的美國(guó)能源部的測(cè)試程序的標(biāo)準(zhǔn)。基準(zhǔn)模型將被假定有一個(gè)塑料桶，非熱控制混合閥門，在正常的自旋周期內(nèi)加熱沖洗實(shí)現(xiàn)62%剩余含水量。4.改進(jìn)的填充控制這個(gè)設(shè)計(jì)方案被定義為提高現(xiàn)有遙感的耐久度。這可以通過(guò)減少目前使用的壓力傳感器或開關(guān)的設(shè)計(jì)的偏差來(lái)完成。這個(gè)設(shè)計(jì)方案，主要涉及垂直軸的設(shè)計(jì)，盡管它有時(shí)只適用于依靠具體填充控制設(shè)計(jì)的水平軸洗衣機(jī)。在一個(gè)典型的垂直軸洗衣機(jī)中，空氣軟管的一端連接洗衣筒底部附近，另一端是連接到一個(gè)壓力開關(guān)。就像水填充浴缸，管內(nèi)空氣是被迫進(jìn)入一個(gè)較小的體積，從而增加了空氣

9、壓力。空氣壓力一直增加，直到它激活壓力開關(guān)，從而關(guān)閉進(jìn)水閥。一個(gè)更精確的水位設(shè)定系統(tǒng)將避免水位超過(guò)洗衣筒，從而大量的減少了所使用的水和能源。制造商提到的性能限制因素包括：1）土壤改變，2）活動(dòng)柔性，和3）磨損。一個(gè)制造商表示，它不清楚減少目前使用的壓力傳感器公差的任何辦法。但由于一些廠商為改善填充控制提供了成本和效率的數(shù)據(jù)，這成為一種方法被分析用來(lái)提高洗衣機(jī)的效率。縮小筒公差這種設(shè)計(jì)方案減少了內(nèi)部洗衣筒和外部洗衣筒之間的空間（環(huán)）。這個(gè)環(huán)空間填滿水，但不增加洗衣機(jī)的容量。更小的內(nèi)洗滌筒和外筒之間的空間會(huì)減少一次洗滌所需填充的水，從而節(jié)省加熱所需的能量。此選項(xiàng)主要適用于垂直軸洗衣機(jī)。在水平軸洗衣

10、機(jī)中，水只占環(huán)水位下部。因?yàn)榇蠖鄶?shù)水平軸洗衣機(jī)的環(huán)是充滿空氣，所以一個(gè)較小的環(huán)不會(huì)有顯著的能源節(jié)省效果。其他因素在確定內(nèi)筒和外筒之間適當(dāng)間隙也很重要。制造商宣稱如果環(huán)太小，可能會(huì)產(chǎn)生內(nèi)洗筒和外筒之間仍然存留的洗衣水的“肥皂水鎖”的問(wèn)題。在旋轉(zhuǎn)干燥環(huán)節(jié)中間隙用來(lái)脫水也是需要的。此外，一定要保留足夠的空間來(lái)允許不平衡荷載籃的偏差。增加旋轉(zhuǎn)干燥環(huán)節(jié)中的洗衣筒旋轉(zhuǎn)速度也可能需要筒與筒之間較大的空間來(lái)允許在較高的旋轉(zhuǎn)速度下更大的偏轉(zhuǎn)。出于這個(gè)原因，縮小筒公差不能與改善水提取的設(shè)計(jì)方案相混合。廠商提到的其他性能的限制因素包括：1）噪音，2）振動(dòng)，3）除砂。一個(gè)廠商表示，洗衣機(jī)轉(zhuǎn)筒內(nèi)在與外在的空間已經(jīng)達(dá)到最

11、小。然而，不同制造商有著不同的洗衣機(jī)滾筒制造公差。因此，制造商提供的成本和效率的數(shù)據(jù)被用來(lái)估計(jì)緊固滾筒公差帶來(lái)的效益。絕熱性的增加這個(gè)設(shè)計(jì)選項(xiàng)增加了外層洗衣滾筒的絕熱性。因?yàn)橐恍崮軙?huì)通過(guò)洗衣的外殼而丟失，所以增加外層洗衣機(jī)滾筒的絕熱性可以在某些衣服需要熱水洗時(shí)，微微的減少一部分的熱量損失。然而，由于洗滌周期很短，水的熱質(zhì)量非常高，添加絕熱層后，溫度相對(duì)較低的滾筒水溫變化很少。計(jì)算機(jī)進(jìn)行140°F條件下20分鐘洗滌周期的模擬，結(jié)果顯示在部分衣物洗滌時(shí)，每添加一英寸的玻璃鋼保溫材料只導(dǎo)致水溫有1-2°F的提高。一些制造商指出，這一設(shè)計(jì)選項(xiàng)會(huì)產(chǎn)生一些小麻煩，應(yīng)該取消。因?yàn)樵S多制

12、造商為這一設(shè)計(jì)選項(xiàng)提供的的成本和效率數(shù)據(jù)分析表示，應(yīng)該提出一種方法來(lái)提高衣物清洗的效率。提高發(fā)動(dòng)機(jī)的效率一些典型的消耗電力占總電量10%的洗衣機(jī)都使用電動(dòng)馬達(dá)。典型的洗衣機(jī)有一個(gè)½-b馬達(dá)。一個(gè)美國(guó)制造商聲明，替換一個(gè)分相式電機(jī)電容器啟動(dòng)電機(jī)可能會(huì)增加電動(dòng)機(jī)10%的效率。制造商提出的性能限制因素包括：1）物理尺寸和2）服務(wù)/安裝。制造商為該選項(xiàng)提供數(shù)據(jù)，但是建議，由于馬達(dá)能量是一個(gè)總能量的一小部分，所以即使電機(jī)能量下降了10%也只能導(dǎo)致減少1%的整體能源消耗。盡管提高發(fā)動(dòng)機(jī)的效率只能小型節(jié)能，但它仍然被作為一個(gè)提高洗衣機(jī)效率的辦法。自動(dòng)調(diào)溫控制混合閥這個(gè)設(shè)計(jì)選項(xiàng)通過(guò)更精確的控制進(jìn)水溫

13、度或熱能填充來(lái)達(dá)到節(jié)省能源。在一個(gè)典型的非恒溫控制進(jìn)水系統(tǒng)，要使用兩個(gè)電磁閥；一個(gè)閥門控制熱填滿水，而其他控制冷填滿水。如果一個(gè)溫水設(shè)置被選中，兩個(gè)電磁閥同時(shí)打開。在溫水清洗模式下，一個(gè)固定部分的熱水和冷水由流量控制設(shè)備所控制。一個(gè)恒溫控制的混合閥（TCMV）是指在洗衣服時(shí)能感覺到水的溫度和調(diào)節(jié)冷熱水供應(yīng)的閥。它可以保持閥門所需的溫水溫度。1996年6月能源部通過(guò)了對(duì)測(cè)試程序的文件，但是家庭用具制造商認(rèn)為沒有必要定義溫控水閥，而應(yīng)定義恒溫控制閥洗衣機(jī)。這是可行的，能源部隨后將家庭用具制造商的建議采納并重新修改上述的定義：“洗衣機(jī)水恒溫控制閥是指能感知水溫和提供適當(dāng)?shù)睦錈崴{(diào)整水溫以保持水溫恒定

14、的洗衣機(jī)閥門”。通過(guò)恒溫控制混合閥可以節(jié)省能量，它可以降低熱洗滌或者溫洗滌的溫度。例如，恒溫控制混合閥可以降低熱洗滌溫度從135°F到130°F的混合熱水（130°F檢驗(yàn)入口條件）溫洗滌同樣可以降低溫度。能源的節(jié)約取決于測(cè)試標(biāo)準(zhǔn)的改變和指定的入口熱水溫度的選擇。附件：外文原稿Washing machine designIn October 1996,Author: Peter j.

According to reasonable rules, different electrical ranking, identified the potential design scheme, which in the process of electric appliance efficiency standa

18、rds promulgated a step closer. Then use filter factor to determine whether further consideration to exclude a particular design. Many input program used in the filter design are provided by the washing machine manufacturers. From trade journals and other household electrical appliances manufacturers

19、 association (AHAM).Although () in the new technology of the analysis of the existing design phase before the rule-making forecast (ANOPR), and the original ANOPR 2, but before the data collected from manufacturers, the existing AHAM input and other stakeholders will still be considered in the repor

20、t. The U.S. department of energy to a supplementary regulations formulate proposal forecast in the future.2. The product categoryUse value to consumers of the appliances are included in the analysis of the products. Category is a subset of the home appliance type, for example, the washing machine is

21、 a kind of home appliance, but compact washing machine is a kind of product category, home appliance products were divided into different types according to different energy utilization. The capacity of the department of energy (doe) divided into categories according to the product or other related

22、performance characteristics, such as product of practicality and efficiency. In general, the definition of a class is to pass from the home appliance manufacturers, trade associations and other related conference seminars to collect data to make. Those who have been designated as the class didn'

23、t pass the doe test program no longer further analysis.At present, the classification of the washing machine as shown in table 1, the corresponding minimum energy efficiency requirements will take effect on May 14, 1994 3.The current product classification and efficiency standards in table 1Product

24、classification efficiency standardsCompact top loadingStandard top loadingSemi-automatic top loadFront loading loadSoap and water saving EF > = 0.90 ft/(KWH/circle)EF > = ft3 / (KWH/circle)No flush heatingNo flush heatingNo flush heatingIn previous regulations, the top load and front-end repro

25、duced washing machine is used to refer to vertical and horizontal axis respectively. Because the horizontal axis machine can produce into top loading device. Product grade difference - is based on how to load instead of how to make your clothes. As a result, the vertical and horizontal axis washing

26、machine became manufacturers design strategy to achieve different levels of efficiency washing machine. According to the current analysis, the product can be classified according to table 2:Table 2 define the product categoryProduct categories definedCompact size is less than 1.6 ft3Standard capacit

27、y greater than 1.6 ft3In this report, because there is no data that can be used on compact product, so only to the standard products are discussed.Design of 3.The change of the design in the design of the washing machine will make the washing machine is energy saving, the U.S. department of energy (

28、doe) released in November 14, 1994, the energy legal rules, design requirements to improve the efficiency of the washing machine. Based on the design of these households manufacturers association of washing machine using range distribution were investigated. Questionnaire for energy utilization and

29、design scheme of data requirement, the cost of initial questionnaire issued, the department of energy (doe) and the manufacturer has carried on the discussion, the laws and regulations on the energy legal discussion results showthat the initial design modification and supplement list of options are

30、home manufacturers to the result of interaction with the U.S. department of energy.Some initial energy design be renamed, to better determine their own technology. Renamed advanced microprocessor control, fuzzy logic control sensors. Configuration of the internal and external dolly tub tolerance has

31、 more stringent requirements. Higher spin speed being redefined to improve water extraction and separation of four stages to achieve the residual moisture content standard, 50%, 40%, 35% and 30%. Four design scheme of the residual water content are the same, but the final moisture content are differ

32、ent. Different requirements for cost and energy efficiency to achieve different levels of residual water content standards.Several design schemes were divided into two or more options. Improve the filling control according to the individual manufacturer originally has the different explanation (in t

33、erms of cost and energy saving is very different) so is divided into two kinds of design scheme: to improve the packing control and automatic filling control. Inverse design options are divided into two kinds of design: horizontal axis and recycle the horizontal axis.1) technical feasibility. Techno

34、logy company business products or in the working prototype will be deemed to be technically feasible.2) made in the installation and service. If in reliable goods, facilities and technical service of the mass production of technology to the effective date of the standard time to services related to

35、the size of the market can be realized, the technology will be considered a viable manufacturing, installation and service.3) had no adverse effect on product utility or availability.4) had no adverse effect on health or safety.To eliminate the cause of the design options were shown further delibera

36、tion (or maintain) discussed in the design of personal options are described below. Don't eliminate the Suggestions in the report design for further analysis in the later report.In the latest report, the combination of efficiency and cost of design options and design options will be analyzed.Inc

37、luded in the discussion of design options limited performance factors (if the same factors by two or more companies to submit). The performance of these restrict factors described by the parameters of the design options. Usually, these factors affect the utility clothes washed pulp machine. The perf

38、ormance factors limit may not out further analysis design options, but describe the design options and should consider performance factors.Benchmark modelA washing machine is used as a reference, benchmark model used to evaluate the energy saving potential and increase the cost of manufacturing of v

39、arious kinds of design options. Potential energy savings are based on a proposed future business entity test procedures (appendix 1) 7. This test is only a new washing machine standard issued will only take effect.Baseline just represents the typical vertical axis washing machine achieve energy effi

40、ciency allows the lowest, in accordance with the designated national home appliance energy laws. At present, all the standard size of the washing machine must achieve energy minimum value 1.18 volt power three per kilowatt-hour, according to the standards of the current U.S. department of energy tes

41、t procedure. Benchmark model will be assumed that there is a plastic bucket, the thermal control mixing valve, in normal spin cycle heat flush residual water content of 62%.The improved filling controlThe design scheme is defined as improving the durability of existing remote sensing. This can be ac

42、hieved by reducing the use of pressure sensor or deviation to complete the design of the switch. This design scheme, mainly related to the design of the vertical axis, although sometimes it applies only to rely on the concrete filling control design of horizontal axis washing machine. In a typical v

43、ertical axis washing machines, air hose connection at the end of the laundry is located near the bottom ofthe cylinder, the other end is connected to a pressure switch. Fill the bathtub like water, and pipe air is forced into a smaller volume, thus increasing the air pressure.Air pressure increases,

44、 until it activate the pressure switch, so as to close the inlet valve. A more accurate water level setting system will avoid water level more than washing cylinder, and reduces a lot of water and energy used. Manufacturers mentioned that the performance of the limiting factors include: 1) the chang

45、e of soil, 2) the activity of flexible, and 3) wear.A manufacturer, said it was not clear to reduce the use of pressure sensor of tolerance of any solution. But due to some vendors to improve filling control provides the cost and the efficiency of the data, it become a kind of method are analyzed to

46、 improve the efficiency of washing machine.The narrow tube toleranceThis design reduces the space between external and internal washing drum washing drum (ring). This ring space is filled with water, but does not increase the capacity of the washing machine. Smaller in the washing drum and the space

47、 between the outer barrel will reduce the water needed for a washing filling, thereby saving the energyfor the heating. This option is mainly suitable for vertical axis washing machine. In the horizontal axis in the washing machine, water ring water level lower. Because most of the horizontal shaft

48、washer ring is filled with air, so a smaller ring does not have a significant energy saving effect.Other factors in determining the appropriate gap between inner cylinder and outer cylinder is also very important. Manufacturers claim that if the ring is too small, may produce inside outside washing

49、cylinder and cylinder of laundry water stayed between "soap water lock" problem. Clearance in the link of rotary dryer is used to dehydration is needed. In addition, be sure to keep enough space to allow the deviation of unbalanced load basket. Increase the laundry in the links of rotary d

50、ryer cylinder rotation speed may need larger space between tube and tube to allow greater deflection under high rotation speed. For this reason, narrow tube tolerance can'tblended with improving the designing plan of water extraction. Manufacturer to some of the other performance of the limiting

51、 factors include: 1) noise, vibration, 2) 3) in addition to the sand.A vendor said, drum washing machine has reached a minimum inner and outer space. However, different manufacturers have different washing machine roller manufacturing tolerance. Therefore, manufacturers provide the cost and efficien

52、cy of data is used to estimate the fastening roller tolerance of benefit.The increase of the insulationThe design options to increase the outer insulation of washing drum. Because some of the heat energy can be lost through the shell of laundry, so can increase the outer insulation of the washing ma

53、chine drum needs in hot water to wash some clothes, part slightly reduce heat loss. However, due to the washing cycle is short, hot water quality is very high, after adding insulation blanket, relatively low temperature of the roller temperature changes very little. Computer under the condition of 1

54、40 ° F 20 minutes wash cycle simulation, the results showed that in some laundry, each inches of glass reinforced plastic thermal insulation material add only result in an increase in water temperature have 1-2 ° F.Some manufacturers, points out that the design option will produce some sma

55、ll trouble, should be cancelled. Because many manufacturers provide a design option of the cost and efficiency of data analysis, said should be a method was proposed to improve the efficiency of the laundry.Improve the efficiency of the engineSome typical power consumption accounts for 10% of the to

56、tal power of washing machines are using an electric motor. A typical washing machine has a 1/2 level - b motor. An American manufacturer statement, replacing a split-phase motor capacitor start motor may increase motor efficiency of 10%. Manufacturers for the performance of the limiting factors incl

57、ude: (1) physical size and (2) service/installation.Manufacturers to provide the data for this option, but suggested that, due to the motor energy is a small part of total energy, so even if the motor down 10% energy will result in 1% reduction in overall energy consumption. While improve the efficiency of the engine can only small
