Guidelines for CCC Version Change of Household Appliances (7): Case Analysis of Kitchen Machinery Cover Protection in GB/T 4706.30-2024

Time：

2026-04-16

Starting from August 1, 2026, the GB/T 4706 series of 3C safety standards for household appliances will be mandatory. This article mainly focuses on the special requirements of GB/T 4706.30-2024 kitchen machinery, combined with the general requirements of GB/T 4706.1-2024, and specifically analyzes the case of kitchen machinery cover protection.

The 3C safety standards for household appliances are updated! Starting from August 1, 2026, the GB/T 4706 series standards will be mandatory. During the transition period, enterprises can independently choose to conduct product certification according to the new or old version standards.

This article mainly focuses on the main content of the new standard GB/T 4706.30-2024 "Safety of household and similar electrical appliances - Part 30: Special requirements for kitchen machinery", combined with GB/T 4706.1-2024 "Safety of household and similar electrical appliances - Part 1: General requirements", and specifically analyzes and interprets cases of kitchen machinery cover protection.

Case Study Analysis of Kitchen Machinery Lid Opening Protection

Unqualified Case

The blender only uses a Hall sensor for lid protection (see Figure 1) and lacks software certification evaluation, failing to meet the requirements of clauses 19.11 and 19.13 in the updated standards GB/T 4706.1-2024 and GB/T 4706.30-2024.

Figure 1

Rectification Plan One

Using a micro switch for lid protection, the micro switch is directly connected to the main motor circuit of the appliance for protection. This solution is the most reliable and cost-effective. (See Figure 2 for details.)

Figure 2

Rectification Plan Two

Use a protection method with dual Hall sensors + dual MOSFETs + dual chips. (See Figure 3)

Figure 3

Comparison of Rectification Plans

Evaluation Dimensions	Rectification Plan One: Micro Switch (Mechanical Type)	Rectification Plan Two: Dual Hall + Dual MOS + Dual Chip (Electronic Type)
Compliance	⭐⭐⭐⭐⭐(Highest) Mechanical switches are classified as "inherently safe" components and are not subject to the electronic component failure clause (19.11.f).	⭐⭐⭐ (Medium) It needs to meet extremely high redundancy design, and it needs to prove that the mutual inspection logic between dual chips has no loopholes.
Cost	⭐⭐⭐⭐⭐ (Extremely Low) Micro switches are mature and inexpensive components.	⭐⭐ (High) Double the number of sensors, power tubes, and chips, and the BOM cost doubles.
Reliability	⭐⭐⭐⭐ (High) Physical contact, strong anti-interference capability, but attention should be paid to waterproofing and oil resistance.	⭐⭐⭐ (Medium) Electronic components are susceptible to the effects of high temperatures, humidity, and magnetic field interference.
Implementation Difficulty	⭐⭐⭐⭐⭐ (Low) Directly connected in series to the main circuit, with simple wiring.	⭐ (High) It is necessary to redesign the PCB, write redundant detection code, and conduct complex fault injection tests.
Recommendation Index	⭐⭐⭐⭐⭐	⭐⭐
