Description

本発明は、２０１８年０７月１８日に中国専利局に提出された出願番号が２０１８１０７９１３４４．７である中国特許出願に対して優先権を主張するものであり、上記出願の全ての内容を引用により本発明に援用する。 The present invention claims priority to a Chinese patent application numbered 201810791344.7 filed with the Patent Office of China on Jul. 18, 2018, and the entire contents of the above application are incorporated by reference. It is incorporated into the present invention.

本発明は、乾燥機の技術分野に関し、例えば、凝縮水循環利用システムおよび乾燥機に関する。 TECHNICAL FIELD The present invention relates to the technical field of dryers, for example, a condensed water recycling system and a dryer.

乾燥機は、加熱することにより、洗濯した衣類の水分を即時に蒸発させて乾燥させる家電機器である。しかし、水洗いした衣類を乾燥機に入れて乾燥する場合、衣類は、自体の材質の特性によりしわ（折り目、しわ、折り跡等）が発生する。このようなしわを解消するために、通常、乾燥機に蒸気発生器または噴霧器を設け、乾燥工程において衣類の表面に水蒸気を噴射することでしわを解消する。 A dryer is a home appliance that heats and immediately evaporates the moisture of washed clothes to dry them. However, when clothes that have been washed with water are placed in a dryer to dry, wrinkles (folds, creases, creases, etc.) occur due to the characteristics of the material of the clothes themselves. In order to eliminate such wrinkles, the dryer is usually provided with a steam generator or a sprayer, and the wrinkles are eliminated by spraying steam onto the surface of the clothes during the drying process.

従来の水蒸気噴射機能付きの乾燥機における水蒸気の水源は、外部からの水道水の供給またはユーザ自身による浄水の追加を採用することが多い。水道水を水源として使用する場合、水道水の硬度が大きいため、乾燥過程においてスケールが発生しやすく、蒸気の乾燥効果に影響を与え、管路を閉塞し、水資源を浪費する。浄水を使用する場合、ユーザ自身による追加が必要となり、使用しにくいとともに、水資源を浪費し、使用コストが高い。 The water source for steam in conventional dryers with steam injection function often adopts an external supply of tap water or the user's own addition of purified water. When tap water is used as the water source, the hardness of the tap water is high, so scale is likely to form during the drying process, affecting the drying effect of steam, clogging pipelines, and wasting water resources. When using purified water, users need to add it themselves, which is difficult to use, wastes water resources, and has high usage costs.

本発明は、噴射する水蒸気の水源が凝縮器から提供される、凝縮水循環利用システムおよび乾燥機を提供する。 The present invention provides a condensed water recycling system and dryer in which the water source for the steam to be injected is provided from the condenser.
