Humidity detection method, device and system for dehumidifier

Abstract

The invention discloses a humidity detection method, device and system for a dehumidifier. The humidity detection method comprises the steps that the current pipe temperature value of a dehumidification system and the current environment temperature value of the dehumidification system are detected through a thermometer bulb; pre-stored multiple pipe temperature, environment temperature and humidity corresponding relations are read, and the different corresponding relations are used for describing the corresponding relations of different humidity values, pipe temperatures and environment temperature; and the current humidity value of the dehumidification system is obtained based on the current pipe temperature value, the current environment temperature value and the corresponding relations. By the adoption of the humidity detection method, device and system for the dehumidifier, the technical problem that starting and stopping anomalies of the dehumidifier occur frequently due to the fact that the placing position of a humidity sensor is unreasonable is solved.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a humidity detection method, device and system for a dehumidifier. Background technique [0002] In the prior art, the humidity detection of the dehumidifier usually relies on the humidity sensor to judge the current humidity of the environment and then control the start and stop of the compressor load. [0003] Using the existing humidity detection scheme using the humidity sensor, the cost is high because the humidity sensor needs to purchase external materials as a whole; High, if the placement of the dehumidifier is unreasonable, that is, there is a large deviation between the humidity value detected by the humidity sensor and the actual humidity of the use environment, when the humidity in some places is high, and even condensed water appears, if the humidity sensor is placed In these positions, after reaching the target humidity and shutting down, there will be a phenomenon ...
