家用和类似用途电器 安全 第 2-4 部分：脱水机的特殊要求

[中文适用范围]： 本部分IEC 60335涉及以下产品的安全： - 独立式电动旋转脱水机 - 具有单独洗涤和脱水容器的洗衣机中的旋转脱水机 适用于家用和类似用途，其容量不超过10公斤干衣物，滚筒周边速度不超过50米/秒，额定电压单相不超过250V，其他器具（包括直流供电设备和电池供电设备）不超过480V。 本标准还适用于非家用但可能对公众造成危险的旋转脱水机，例如供外行在商店、轻工业和农场使用的旋转脱水机，以及公寓楼或自助洗衣店共用的旋转脱水机。 本标准尽可能处理所有人员可能遇到的合理可预见的危险。但通常不考虑以下情况： - 由于身体、感官或精神能力不足，或缺乏经验和知识而无法在没有监督或指导的情况下安全使用设备的人员（包括儿童）； - 儿童玩耍设备。 需要注意： - 用于车辆、船舶或飞机的设备可能需要额外要求； - 许多国家的国家卫生部门、劳动保护部门、国家供水部门和类似机构可能规定了额外要求。 本标准不适用于： - 专为工业用途设计的设备； - 在特殊条件下使用的设备，例如存在腐蚀性或爆炸性环境（灰尘、蒸汽或气体）的场所。 [外文原描述]： IEC 60335-2-4:2023 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 the comprehensive content of the Standard. IEC 60335-2-4:2023 EXV includes the content of the references made to IEC 60335-1:2020. IEC 60335-2-4:2023 deals with the safety of: - stand-alone electric spin extractors, and - spin extractors incorporated in washing machines that have separate containers for washing and spin extraction for household and similar purposes that have a capacity not exceeding 10 kg of dry cloth and a drum peripheral speed not exceeding 50 m/s, their rated voltages 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. Appliances not intended for normal household use but which nevertheless can be a source of danger to the public, such as spin extractors intended to be used by laymen in shops, in light industry and on farms and spin extractors for communal use in blocks of flats or in launderettes, are within the scope of this standard. As far as is practicable, this standard deals with the reasonably foreseeable hazards presented by appliances that are encountered by all persons. 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 appliances 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: - appliances intended exclusively for industrial purposes; - 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). This eighth edition cancels and replaces the seventh edition published in 2021. 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 (20.103, 20.104, 22.101); c) addition of test probe 19 for accessibility of live parts and moving parts (8.1.1, 20.2); d) addition of accessible surface temperature limits (11.3, 11.8); e) specified operating conditions for battery operated appliances (B.11.1). 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.
