Dehumidifying and drying device

Abstract

The invention discloses dehumidifying and drying device, which comprises a microprocessor, a plurality of humidity sensors and a plurality of signal conditioning modules corresponding to the humidity sensors in number, and is characterized by further comprising a key input module, driving modules, a heater and a fault detection module. The humidity sensors are connected with the microprocessor through the corresponding signal conditioning modules, the microprocessor is connected with the heater through the driving modules, the key input module is connected with the microprocessor, an input end of the fault detection module is connected with the heater, and an output end of the fault detection module is connected with the microprocessor. Aiming to solve the problems that the temperature of a heater of a humidifier in the prior art cannot change along with change of the external environment and the humidifier is complicated in use and easy to be damaged after long-term use, the dehumidifying and drying device is simple in structure and capable of changing the temperature of the heater according to needs and has an alarming function.

Description

Technical field [0001] The invention belongs to the technical field of electrical control, and particularly relates to a dehumidifying and drying device. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for the quality of life. In summer, the indoor humidity is relatively high, and the human body often feels very uncomfortable, which greatly affects people's work and life quality. At the same time, due to the high humidity, Mosquitoes are easy to breed, and the health and safety status is worth worrying about. At present, the dehumidifiers on the market are relatively simple and do not provide a human-computer interaction interface. They are often set to a fixed value before leaving the factory. People cannot change the temperature of the heater as the external environment changes. It is a great trouble. At the same time, the dehumidifier has no alarm system, so that there is a problem in the use process,...
