家用和类似用途电器.安全.第2-7部分:洗衣机的特殊要求

[中文适用范围]： 本部分IEC 60335涉及家用和类似用途电动洗衣机的安全性，这些洗衣机用于洗涤衣物和纺织品，其额定电压不超过单相器具250V和其他器具（包括直流供电器具和电池供电器具）480V。本标准还涉及使用电解质代替洗涤剂的家用和类似用途电动洗衣机的安全性。这些器具的附加要求在规范性附录CC中给出。注101：在资料性附录DD中提供了用于确保配备动力驱动绞拧器的洗衣机具有可接受的电气和热危害防护水平的指导。不适用于正常家庭使用但仍可能对公众构成危险的器具，例如供非专业人员在商店、轻工业和农场使用的器具，也在本标准范围内。本标准尽可能处理洗衣机对家庭内外所有人造成的常见危险。然而，一般而言，它不考虑以下情况：- 由于身体、感官或智力能力不足或缺乏经验和知识而无法在无人监督或指导的情况下安全使用器具的人（包括儿童）；- 儿童玩耍器具。请注意：- 用于车辆、船舶或飞机的洗衣机可能需要附加要求；- 在许多国家，国家卫生当局、国家劳动保护当局、国家供水当局和类似当局规定了附加要求。本标准不适用于：- 专为工业用途设计的洗衣机（ISO 10472-2）；- 用于特殊条件（如腐蚀性或爆炸性环境（粉尘、蒸汽或气体））的器具；- 包含蒸汽发生装置且蒸汽压力超过50kPa的洗衣机；- 商业用途的洗衣机，包括在公寓楼或自助洗衣店中公用的洗衣机（IEC 60335-2-122）。 [外文原描述]： IEC 60335-2-7:2024 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60335-2-7:2024 EXV includes the content of the references made to IEC 60335-1:2020. IEC 60335-2-7:2024 deals with the safety of electric washing machines for household and similar use, that are intended for washing clothes and textiles, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances including direct current (DC) supplied appliances and battery-operated appliances. This standard also deals with the safety of electric washing machines for household and similar use employing an electrolyte instead of detergent. Appliances not intended for normal household use but which nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by washing machines that are encountered by all persons in and around the home. However, in general, it does not take into account: - persons (including children) whose: physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction; - children playing with the appliance. Attention is drawn to the fact that: - for washing machines intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary; - in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities. This standard does not apply to: - washing machines intended exclusively for industrial purposes (ISO 10472-2); - appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); - washing machines incorporating steam generating devices in which steam is produced at a pressure exceeding 50 kPa; - washing machines for commercial use including those for communal use in blocks of flats or in launderettes (IEC 60335-2-122). This ninth edition cancels and replaces the eighth edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with IEC 60335-1:2020; b) conversion of some notes to normative text (Clause 1, 20.104, 20.105); c) addition of requirements for restarting the spin cycle of agitator washing machines and impeller washing machines (20.108); d) addition of requirements for remote operation (22.51); e) application of test probe 19 has been introduced (8.1.1, 20.2). This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
