Description

Technical Field

[0001] The invention belongs to the technical field of intelligent toilet manufacturing, and relates to a detection device for an intelligent toilet cover, in particular to a ground resistance test device for an intelligent toilet cover. Background Art

[0002] Grounding resistance is an important parameter to measure whether the grounding state is good. Grounding resistance is the resistance encountered by the current flowing into the earth through the equipment and then flowing through the earth to another grounding body or spreading to a distant place. The value of grounding resistance reflects the good degree of contact between the electrical device and the ground. At present, grounding resistance meters or multimeters are often used to directly measure the grounding resistance of equipment to determine whether the equipment is reliably grounded.

[0003] Grounding resistance is one of the important safety indicators of Class 0I and Class I household appliances, and smart toilets belong to Class I household appliances. Although GB4706.1-2005 and GB4289-2005 have clear regulations on how to accurately measure the grounding resistance value, different test methods will bring different test errors. The safety standard for household appliances stipulates that the grounding resistance should include the sum of the resistances from the grounding wire column or grounding electrode to each easily accessible non-live metal part. The principle of contact resistance measurement is Ohm's law R=U / I. It is stipulated that a constant current source of 25A is used, and an AC voltmeter is used to measure the voltage difference between the two ends of the resistor, and then calculated using Ohm's law. The grounding resistance test of the smart toilet seat usually involves the following resistance values: Ra: the sum of the material resistance of each easily accessible non-live metal part and the contact resistance between them; Rb: the contact resistance between the grounding wire post and the non-live easily accessible metal part; Rc: the contact resistance between the power cord and the grounding wire post; Rd: the material resistance of the power cord; Re: the contact resistance between the measuring probe and the grounding electrode; Rf: the contact resistance between the power cord and the grounding electrode; Rg: the contact resistance between the measuring probe and the easily accessible non-live metal part.

[0004] my country's patent (announcement number: CN211603347U; announcement date: 2020-09-29) discloses a ground resistance tester and a withstand voltage tester that prevent accidental contact. The ground resistance tester and the withstand voltage tester include a ground resistance tester main body, and four connecting rods are fixedly connected to the bottom of the ground resistance tester main body. One end of the four connecting rods is fixedly connected to the top of the withstand voltage tester main body, and sliding grooves are provided on both sides of the ground resistance tester main body and both sides of the withstand voltage tester main body.

[0005] The ground resistance tester and withstand voltage tester disclosed in the above patent document need to be manually connected to the workpiece to be tested during use. During use, the wires need to be frequently manually disassembled and assembled to achieve the ground resistance values ​​at different positions on the test workpiece. Therefore, it is inconvenient to use and has low work efficiency, and is not convenient for automated ground resistance testing of smart toilet lids. Summary of the invention
