This standard applies to the safety of electric washing machines for household and similar purposes for washing clothes and textiles, with a rated voltage of not more than 250V for single-phase power supply appliances and not more than 480V for other appliances. Appliances not for ordinary household use are included in the scope of this standard as long as they may be dangerous to the public, such as appliances used by the infirm in shops or in light industry and farms. As far as practical, this standard discusses the common hazards presented by appliances that people encounter at home and near home. This standard does not usually take into account: - the use of appliances by unsupervised children or infirm people; - the use of appliances by children.

GB4706.24—2000
This standard is equivalent to IEC60335-2-7:1993 Safety of household and similar electrical appliances Part 2 Particular requirements for washing machines and its amendments No. 1 and 2 (1998, 1999). It is the first revision of GB4706.24-1991 Safety of household and similar electrical appliances Particular requirements for washing machines. This standard should be used in conjunction with GB4706.1-1998 General safety requirements for household and similar electrical appliances.
The parts marked with *applicable\ in this standard indicate that the corresponding provisions in GB 4706.1-1998 are applicable to this standard. The parts marked with "replace" or "modify" in this standard shall be subject to this standard; the parts marked with "addition" in this standard indicate that in addition to complying with the corresponding provisions in GB 4706.1-1998, they shall also comply with the provisions added in this standard. This standard is consistent with IEC The main differences between 335-2-7 are: In 2.2.9, the water temperature is changed to: 50℃±5℃ for appliances without heating elements; In 6.1, it is added that the appliances should be Class 01 appliances. This standard mainly revises GB4706.24-1991 in the following aspects: - In 6.2, it is clearly stipulated that the waterproof level of the appliance should be at least IPX4; - In 7.1, only the maximum allowable water level of washing machines without automatic water level control and the safety release mechanism of electric squeezers should be marked with the operating instructions are retained. The 18th chapter, Durability, is not applicable. That is, the 48-hour test at 1.1 times the rated voltage and 0.9 times the rated voltage is cancelled. The 15th chapter, Moisture Resistance Test, is a 48-hour test for all appliances. Therefore, the test time for anti-corrosion appliances is changed from 168 hours to 48 hours.
-20.101 and 20.102\ Before the cover of the top-opening and front-opening drum-type washing machines is opened more than 75 mm, the interlocking device shall disconnect the power supply of the motor. \Change the "75 mm\" to \50 mm\. This standard will replace GB4706.24-1991 from the date of implementation. This standard is proposed and managed by the National Technical Committee for the Promotion of Household Electrical Appliances. The main drafting unit of this standard is China Household Electrical Appliances Research Institute. The main drafters of this standard are Wang Huilian, Li Xianli, and Xu Li. The National Technical Committee for the Standardization of Xin Electrical Appliances is entrusted with the responsibility for the interpretation of this standard. GB4706.24—2000
IEC Foreword
1) IEC (International Electrotechnical Commission) is a worldwide standardization organization consisting of all national electrotechnical committees (IEC National Committees). Its purpose is to promote international cooperation on all standardization issues in the electrical and electronic fields, followed by some other additional activities, such as the issuance of IEC International Standards. The preparation of international standards is entrusted to technical committees. In this preparation process, any IEC National Committee can participate in the issues of interest. International, governmental and non-governmental organizations also participate in this preparation. IEC and the International Organization for Standardization (ISO) work closely together under the conditions determined by the agreement between the two organizations.
2) IEC's formal resolutions or agreements on technology are formulated by technical committees in which all national committees interested in these issues participate, and therefore, they all represent and explain an international consensus on the issues involved as faithfully as possible. 3) IEC publishes standards, technical reports or guidelines for international use in a recommended manner and is accepted by national committees. 4) In order to promote international coordination, IEC hopes that national committees will adopt IEC standards in their national or regional standards where conditions permit. Any differences between national or regional standards corresponding to IEC standards and this standard should be clearly indicated in the latter. 5) IFC has not established a procedure for the approval mark. IEC is not responsible for any claim that a device complies with an IEC standard. This standard was prepared by IEC Technical Committee 61 (Safety of Household and Similar Electrical Appliances). IEC60335-2-7 Fourth Edition, replacing the 3rd Edition of 1984 and Amendment 1 of 1988. This standard is based on the following documents:
61(C0)754 754A
Voting Report
61(CO)768
All materials related to the adoption of this standard can be found in the voting report shown in the table above. This standard is used in conjunction with the latest version of IEC 60335-1 and its amendments. This standard is based on the 3rd edition of IEC 60335-1 (1991).
This standard supplements and modifies the corresponding clauses of IEC 60335-1, thereby transforming it into an IEC standard: Safety requirements for electric washing machines. IEC 60335-1 clauses not mentioned in this standard may be used as long as they are reasonable. Where the words "add", "modify" or "replace" are marked in this standard, the relevant clauses in this standard shall be modified accordingly. Notes
are expressed in the following fonts:
Requirements, print.

The definitions in the clauses are those in Chapter 2 of the IEC The additional clauses based on 60335-1 start from 101. The additional annexes are indicated by letters AA, BB, etc. 2
The following differences exist in some countries
-2.2.9: Use of different sizes of clothing. The initial water temperature of machines without heating elements and without squeezers is 71°C (USA). - Chapter 3: Restriction of DC components in the neutral line of the appliance (Australia). - 6.1: Class 01 appliances are allowed (China and Japan). - 6.2: IPX0 appliances are allowed (Canada and the United States). - 11.7: Durability tests are different (USA). - 15.101: Different tests are carried out (USA). GB4706.24-2000
19.7, appliances without program controllers are operated until steady conditions are established (USA). 19.101: Extra contact seats are not indicated as required by Note 2. Operation without water is not considered an abnormal condition as specified in Note 4 (USA.
22.6, different tests are performed (USA). 22.101: Test at twice the permissible water inlet pressure or 1.5 MPa, whichever is higher (Australia and New Zealand). Test at twice the permissible water inlet pressure or 2.0 MPa, whichever is higher (Norway). No test is performed (country).
—Annex AA: Use of different detergents (USA). Appendix BB, other tests on synthetic rubber parts (USA). 1 Scope

This standard applies to the safety of electric washing machines for household and similar purposes for washing clothes and textiles, with a single-phase power supply rated voltage not exceeding 250V for appliances and 480V for other appliances. Notes
1 Washing machines may be combined with devices that heat water, dehydration and drying operations. 2 Washing machines with centrifugal dehydration functions shall also comply with the relevant requirements of GB4706.26. Washing machines with drying functions shall also comply with GB4706.20 related requirements. 3 Washing machines driven by electricity and other forms of energy are also within the scope of this standard. Appliances that are not for ordinary household use are included in the scope of this standard as long as they may be dangerous to the public, such as appliances used by the infirm in shops or used in light industry and farms.
Note 4, such as washing machines shared in residential areas or laundries. As far as practical, this standard discusses the common hazards presented by appliances that people will encounter at home and near home. This standard does not usually take into account:
The use of appliances by unsupervised children or infirm people, and the use of appliances by children.
5 The following facts should be noted:
