The basic configuration of the vacuum cleaner air performance table includes the original basic items of voltage, current, input power, power factor, suction power, flow rate, vacuum degree, and efficiency, supplemented with a complete set of testing items specified by European and American standards. It is divided into mandatory core items, durability condition testing, ancillary performance testing, and environmental matching verification items, and corresponding execution standards are marked.

Mandatory supplementary air performance testing project for European and American standards

1. Full condition testing of air volume vacuum characteristic curve

The original data collection was only single point, and the standard required complete gradient testing: gradually plugging the suction port, continuously recording the vacuum degree and air flow rate, and generating a complete performance characteristic curve, which is a key requirement for IEC and American standards to determine the operating range of vacuum cleaners; It can export curve documents and is also a standard extension function of the device.

2. Energy efficiency grading test under rated operating conditions

1. Air energy efficiency: Accurate calculation of suction power/motor input power, matched with IEC62885 vacuum cleaner energy efficiency level classification;

2. The overall energy efficiency of the machine is calculated by distinguishing between three operating conditions: no-load, rated load, and rated blockage.

3. Dust load attenuation test

Add standard test dust to the vacuum chamber, simulate actual dust accumulation, and continuously test:

The decay rate of vacuum degree, flow rate, input power variation, and continuous working stability, as well as the determination of the impact of filter blockage on the performance of vacuum cleaners, are essential items for mass production quality inspection of cleaning appliances.

4. Different suction head adaptation performance testing

Paired with standard floor brushes, crevice suction nozzles, brush suction heads, and other accessories that meet national/European and American standards, the vacuum, flow rate, and suction power of each accessory are tested separately to evaluate their matching performance.

Electrical safety supporting testing

1. No load/full load current fluctuation test: instantaneous peak current during motor start-up and stability of long-term operating current;

2. Temperature rise linkage detection (extended module): The temperature rise of the motor, power cord, and body shell under long-term working conditions meets the general safety standards for household appliances;

3. Startup performance test: Start and stop multiple times under rated voltage and lower limit voltage, record the startup power and duration.
