家用和类似电器 - 安全 - 第 2-11 部分：滚筒式烘干机的特殊要求

[中文适用范围]： 本部分 IEC 60335 涉及家用和类似用途电动滚筒干衣机的安全，其额定电压单相器具不超过 250 V，其他器具（包括直流供电器具）不超过 480 V。本标准适用于具有干燥功能的洗衣机的干燥功能。本标准还涉及热泵型滚筒干衣机的安全。这些器具可能使用易燃制冷剂。对于这些器具的附加要求见规范性附录 AA。不适用于正常家用但仍可能对公众造成危险的器具，如供商店、轻工业和农场的外行人使用的器具，也在本标准范围内。例如公寓楼或自助洗衣店共用的滚筒干衣机。本标准尽可能处理所有人员遇到的器具常见危险。然而，一般来说，不考虑以下情况：- 因身体、感官或精神能力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器具的人员（包括儿童）；- 儿童玩耍器具。注意以下事实：- 对于拟用于车辆、船舶或飞机上的器具，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、国家供水当局规定了附加要求。本标准不适用于：- 专门用于工业用途的器具；- 在特殊条件下使用的器具，如存在腐蚀性或爆炸性环境（粉尘、蒸气或气体）；- 包含蒸汽发生装置的器具，其中蒸汽产生的压力超过 50 kPa。 [外文原描述]： IEC 60335-2-11:2024 deals with the safety of electric tumble dryers intended for household and similar purposes, 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 applies to the drying function of washing machines having a drying cycle. This standard also deals with the safety of heat pump type tumble dryers. These appliances may use flammable refrigerants. Additional requirements for these appliances are given in normative Annex AA. 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. Examples of such appliances are tumble dryers for communal use in blocks of flats or in launderettes. As far as is practicable, this standard deals with the common 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. 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); - appliances incorporating steam generating devices in which steam is produced at a pressure exceeding 50 kPa. 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, Annex AA); c) implement new definitions to type of appliances (3.5.102, 3.5.103, 3.5.104); d) specific requirements have been added in 22.51 for remote operation; e) specific requirements have been added in Clause 24 for motor running capacitors; f) new modifications in Annex R; g) update of requirements for appliance that use flammable refrigerants in Clause 21 and Clause 22 of Annex AA; 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.
