Description

Heat pump vacuum clothes drying device

Technical Field

The invention relates to a heat pump vacuum clothes drying device, and belongs to the technical field of heating ventilation drying.

Background

Laundry dryers are one type of washing machine that is commonly used to remove moisture from garments and other textiles after water washing and dewatering. Most laundry dryers include a rotating drum, an inner drum driven by a belt, with hot air around the drum for evaporating moisture. The clothing drying cylinder adopts the principle of forward and reverse rotation of the roller to achieve the effect of no winding of clothing drying articles.

Patent CN105297372a discloses a clothes drying system and a drying method, a washing and drying integrated machine and a clothes dryer. The clothes drying system comprises an air duct, a heater, a condenser and a fan, wherein the heater, the condenser and the fan are arranged in the air duct, the condenser is arranged close to an air inlet of the air duct, the heater is arranged close to an air outlet of the air duct, a dehumidifier is arranged in the air duct between the heater and the air outlet, and the dehumidifier is used for adjusting the concentration of water vapor in air flowing through the dehumidifier in the clothes drying process. In the later stage of stoving, stop heater and condenser, the steam in the circulating air is absorbed by the dehumidifier, and the air becomes dry, and the steam that remains in the absorption clothing when the dry air passes through comparatively dry clothing again, does not need to continue consuming electric energy and running water, and does not have the damage to clothing. After the drying is finished, water vapor is left in the dehumidifier, and when the next drying is carried out, hot air removes the water vapor in the dehumidifier while drying clothes in the early and middle stages, so that the dehumidifier can be regenerated.

As another example, patent CN106480673a discloses a drying method for reducing wrinkles of clothes, which includes: acquiring the weight of clothes to be dried; comparing the weight of the clothes to be dried with the rated drying weight, and prompting a user to take out part of the clothes when the weight of the clothes to be dried exceeds the rated drying weight; and drying the clothes. The washing and drying integrated machine adopting the drying method is also provided. According to the invention, the weight of the clothes to be dried is compared with the rated drying weight, when the weight of the clothes to be dried is larger than the rated drying weight, a user is prompted to take out part of the clothes within a preset time period, and the rest of the clothes are dried until the weight of the clothes to be dried is not larger than the rated drying weight, so that wrinkles on the dried clothes can be effectively reduced, and the drying effect of the clothes is improved.

The heat pump technology is to transfer heat energy from a low-temperature heat source to high-temperature heat source equipment, input one part of electric energy can obtain multiple times of input electric energy heat, and the heat pump technology can be used for recovering part of heat energy from high-temperature high-humidity waste air and has low drying temperature. However, in general, the steam drying process accelerates the evaporation of moisture in the laundry by increasing the temperature of the laundry, and the laundry is wrinkled and fiber damaged due to the excessive temperature. In order to save energy consumption and accelerate the evaporation of water in clothes, the invention provides a vacuum rapid evaporation combined with heat pump heating technology.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, realize the rapid evaporation of water in clothes by utilizing vacuum, and realize energy conservation in the drying process by utilizing a heat pump technology.

In order to achieve the above purpose, the present invention adopts the following technical scheme:
