Abstract

The invention provides a negative pressure drying device for drying clothes in an incubator (room) under negative pressure conditions. In the incubator (room) with heating constant temperature, the clothes to be dried are placed in the air-insulated soft packaging bag. One part of the air-insulated flexible packaging bag is equipped with a connecting pipe connected to the gas-liquid separator, and the top of the gas-liquid separator is another A vacuum pump is connected to generate negative pressure, and the evaporation speed of the liquid under negative pressure conditions will be greatly improved. Due to the increased discharge and evaporation speed of the liquid under negative pressure conditions, the load of heating energy is reduced, and the loss of heated air is reduced under the barrier of the air-insulating soft packaging bag, so as to achieve the purpose of fast and energy-saving drying of clothes.

Description

Technical field [0001] The invention relates to a negative pressure drying device for drying clothes in an incubator (room) under negative pressure conditions, belonging to the drying technical field. Background technique [0002] Existing clothes drying devices are generally oven (room) dehumidification type, drum type, etc., and the drying clothes device based on oven (room) dehumidification type. In the process of drying clothes, more than 80% of the heat energy will be taken out by the air flowing to discharge moisture and liquid, resulting in a waste of energy. When other component liquids are discharged, it is not easy to recycle. Contents of the invention [0003] In order to overcome the disadvantages of low energy utilization rate and inability to conveniently recycle the liquid in the clothes in the existing clothes drying device. [0004] The invention provides a negative pressure drying device for drying clothes in an incubator (room) under negative pressure ...
