[0002] A dehumidifier refers to a device that reduces the absolute humidity in the air by refrigeration, maintains the relative humidity in a space at an appropriate level, so that items and household goods that are prone to moisture absorption are not affected by moisture, do not mildew, and products, medicines, etc. with high humidity requirements can be manufactured, produced, and stored within the humidity range they require.

[0003] During operation, the fan sucks in humid air, condenses water droplets through a heat exchanger, and discharges the dry air. The cycle reduces the indoor humidity. To prevent dust and debris from being brought in by the humid air, causing pollution and blockage, a filter screen needs to be installed at the intake part of the dehumidifier.

[0004] The filter screen is prone to dust attachment after long-term use. Removing it for cleaning affects the operation of the dehumidifier. Cleaning without shutting down the machine loses the protection function, and there is a gap period during the interruption of the dehumidifier's operation, unable to meet the requirement of automatically replacing the filter screen without shutting down the machine, resulting in a reduction in functionality. Therefore, a dehumidifier with a replaceable filter screen is proposed to solve the above problems. Content of the Utility Model
