ドラム式洗濯機の乾燥方式について(ヒーター式 or ヒートポンプ式)

f:id:keiwt:20141213141804p:plain

どう見てもヒートポンプ式の方が良いように思えます。
しかし、ネット上にはヒートポンプ式の故障が多発するとの記事をよく目にします。

空気を循環させるという点で内部のホコリが詰まるようです。
そのメカニズムを解明しなくては。

Bestbuyはどうか

どうやら、SamsungやLGが人気のようです。
価格も日本のものよりだいぶ安いですね。

さて、乾燥方式はというと。

5 temperature settings As well as precise temperature control with a variable heater provides the proper heat for different fabric types to ensure that clothes are not overdried. 5段階の温度を設定できるようです。おそらく、ヒーター式ですね。

VENTLESS CONDENSING DRYING SYSTEM(http://www.lg.com/us/washer-dryer-combos/lg-WM3997HWA-washer-dryer-combo) こちらはベントレス。つまり、洗濯機外に湿気を出さないやつですね。
今の日本のドラム式洗濯機は基本ベントレスだと思います。

  1. Condensation dryer – this works similar to the traditional dryer where cool and dry room air is pulled in, heated and discharged in a closed path and through wet clothes so that they become dry.
A blower helps move the air inside.
This air moves through a heating system so that it reaches proper drying temperature.
The heated air is then made to pass through the wet clothes, collecting moisture in the process.
The moisture-laden air gets redirected to the heater.
It goes back to the clothes chamber to repeat the process if the clothes still contain moisture.
It is basically a recirculation system where cold water is used as moisture condensing medium.

2. Heat pump dryer – air is made to go through a heat pump to condense water vapor and subsequently forwarded into a drain pipe or into a collection chamber. This is then reheated to be used again on clothes. Compared to traditional or condensation dryers, the heat pump type consumes less energy.

海外でも、ヒートポンプ式が節電できると言われています。
