Description

Technical Field

[0001] The utility model relates to the technical field of input power testing, and more specifically, to an input power testing device for household appliances. Background Art

[0002] Household appliances, as necessities in modern family life, cover various electrical and electronic appliances used in households and similar places. Given the wide variety of household appliances, their power consumption naturally varies significantly. Although the electrical power is clearly marked on many appliances, over time, factors such as the increasing service life and aging of the equipment often lead to a significant deviation between the actual electrical power of the appliance and the electrical power at the time of factory shipment. To ensure the safety and energy efficiency of the appliances, it is particularly important to regularly use an input power testing device to detect the power of household appliances. During the use of common input power testing devices, since the height of the device is fixed, while the lengths of the plug connecting wires of household appliances vary, a shorter connecting wire may not be fully inserted into the testing device, affecting the accuracy and efficiency of the input power test.

[0003] For example, Chinese Patent CN213986630U discloses an input power testing device for household appliances. The device includes components such as a base, a testing box, a connecting rod, a support plate, a timer, a mounting plate, an ammeter, a terminal, a wire, a plug, a socket, a microcomputer, a clamping mechanism, a threaded rod, a clamping block, etc., which can clamp and fix the appliance to be tested and protect the appliance to be tested through a rubber soft pad. Due to the wide variety of household appliances and the different lengths of their plug connecting wires, however, the height of the above-mentioned testing device is fixed. When encountering a household appliance with a shorter plug connecting wire, the plug may not be fully inserted into the testing device, resulting in an inability to perform an accurate input power test, thereby reducing the testing efficiency and affecting the accuracy of the test results.
