Introduction

GB/T 4706 "Safety of Household and Similar Electrical Appliances" adopts most of IEC 60335.On this basis, GB/T 4706 refers to the structure of IEC 60335 is divided into several parts, consisting of general requirements and special requirements. Part 1 is general requirements, and the other parts are for products covered by special requirements, their safety requirements are general requirements used in combination with the special requirements.

The requirements include supplements and modifications to the corresponding clauses in the general requirements to provide complete requirements for each product.

This document is the protection requirements for electrical, mechanical, thermal, fire and radiation risks when the appliance is used normally in accordance with the instructions.

This document also covers abnormal conditions that may occur during use and considers how electromagnetic interference may affect the safe operation of the equipment.

This document has taken into account the requirements specified in GB/T 16895 "Low Voltage Electrical Installations". The appliance is connected to the power supply in accordance with the electrical wiring rules.

requirements are coordinated.

If multiple functions of an appliance involve other parts of GB/T 4706, the other parts shall apply to the appliance separately as long as it is reasonable.

Each function. If applicable, consider the impact of one function on other functions.

When no additional requirements are given in other parts for hazards already included in this document, GB/T 4706.1 applies.

GB/T 4706 is a standard covering appliance safety and takes precedence over general standards/horizontal standards covering the same subject.

This document is used in conjunction with GB/T 4706.1-2024 "Safety of Household and Similar Electrical Appliances Part 1: General Requirements".

The part marked "applicable" in the document indicates that the corresponding clauses in GB/T 4706.1-2024 are applicable to this document; the part marked "replaces" in this document indicates that the corresponding clauses in GB/T 4706.1-2024 are applicable to this document.

For the parts marked as "added" in this document, in addition to complying with GB/T 4706.1-2024, the provisions in this document shall prevail.

In addition to the corresponding clauses, the clauses added in the clauses of this document must also be complied with; the part of this document marked "modified" means that in GB/T 4706.1-the relevant provisions of 2024 will be modified.

Safety of household and similar electrical appliances Part 26: Particular requirements for centrifugal dehydrators

1 Scope

This chapter of GB/T 4706.1-2024 is replaced by the following.

This document specifies the safety of centrifugal dehydrators for household and similar purposes. This document applies to single-phase appliances with a rated voltage not exceeding 250V, other appliances with rated voltage not exceeding 480V, drying load capacity not exceeding 10kg, rotating drum linear speed not exceeding 50m/s A separate electric centrifugal extractor or a centrifugal extractor in a washing machine with separate containers for washing and dehydrating.

This document also applies to appliances not intended for normal household use but which may nevertheless present a hazard to the public, such as those intended for use in shops, light industry and agriculture.

Equipment used by non-professionals in the field.

As far as is practical, the hazards presented by the appliances covered by this document are common to all persons in and around the home.

However, in general, this document does not address.

---The following groups (including children) - due to a physical, sensory or mental impairment, or - Due to lack of experience and knowledge, Situations where the appliance cannot be used safely without supervision or instruction.

--- Condition of children's play equipment.

Note the following.

--- For equipment intended for use in vehicles, ships or aircraft, additional requirements may be required;

--- National authorities may impose additional requirements on equipment.

This document does not apply to.
