Household appliance service environment simulation device

Abstract

A household electrical appliance service environment simulation device disclosed by the present invention comprises a PLC controller and a simulation box body, a spraying mechanism and an illumination mechanism are arranged at the upper part in the simulation box body, the spraying mechanism is connected with a corrosion medium storage box, and a heating mechanism and a ventilation mechanism are arranged on the inner side wall of the simulation box body. A support frame is arranged at the lower part in the simulation box body, and a to-be-tested electric appliance is placed on the support frame and is connected with a power supply; the spraying mechanism, the heating mechanism, the illumination mechanism and the ventilation mechanism are all connected with the PLC. A to-be-tested electric appliance is connected with a power supply and is placed in the simulation box body, dynamic testing is carried out when the to-be-tested electric appliance is in a working state, factors, such as structural stress, processing stress and system operation stress, influencing product base material corrosion are considered in whole machine testing, key weak parts, influencing the service life, of a product in the actual service process are scientifically evaluated, and the test accuracy is improved. Therefore, weak spots are improved, and life prediction and design of the household appliance product are realized.

Description

technical field [0001] The invention relates to the technical field of home appliance service environment simulation, in particular to a home appliance service environment simulation device. Background technique [0002] With the development of society and the advancement of science and technology, people's requirements for the quantity and quality of various household appliances are constantly increasing. Correspondingly, household appliances have put forward higher requirements for environmental adaptability and reliability. Various types of environmental suitability and reliability tests are required. [0003] The environmental adaptability and reliability test of household appliances is mainly based on the conventional salt spray test system. Currently, it can only reflect the corrosion resistance of the substrate in coastal or island environments, and cannot evaluate the corrosion resistance in other corrosive environments. In other environments with special corrosive ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the difficulty in adapting to other environments with special corrosive media and the failure of the unit in the prior art, the conventional salt spray test system cannot reflect the processing stress, structural stress and dissimilar material connection. Influenced by material corrosion resistance, it is impossible to evaluate the service life of the whole machine and other shortcomings. The purpose of the present invention is to provide a service environment simulation device for household appliances
