Embodiment Construction
[0015] Combine below figure 1 Describe the operation process of this system in detail.
[0016] Turn on the power to enter the drying program, set the drying temperature, and the two circulating fans start to work, passing the humid air from the upper part of the drum into the cooling channel of the semiconductor cooling chip array, wherein the semiconductor cooling chip array is arranged in two rows, with the cold side facing inward Place, hot side out. At the same time, the semiconductor refrigeration chip starts to work, the temperature of the cold end drops, and the humid air condenses on the fins of the cold end when it is cooled in the cooling channel. The fins at the cold end are coated with a hydrophobic coating, and the condensed water flows into the gas-liquid separation under the action of gravity. device and then discharged into the environment. The separated cold air then enters the right cooling channel and the left cooling channel of the semiconductor refriger...

The invention provides a semiconductor heat pump dehumidification clothes-drying system and clothes-drying method, and belongs to the field of drying. The system and method aim to solve a series of problems that the current dehumidification products are loud in noise, high in energy consumption and not suitable for drying fabric with poor heat resistance. The system includes a box body, a semiconductor heat pump module, a voltage controller, a circulating fan and a gas-liquid separation device, wherein the semiconductor heat pump module consists of a semiconductor cooling chip array, a cold end heat transfer structure and a hot end heat transfer structure. Compared with similar products, the system has the advantages of being simple in structure, easy in maintenance, low in energy consumption and controllable in drying temperature, and discharging no wet and hot air.
Description
technical field [0001] The invention belongs to the field of drying, and in particular relates to a semiconductor heat pump dehumidification drying system and a drying method. Specifically applied to the laundry drying process on the washing machine. Background technique [0002] At present, the washing machines with drying function on the market can be roughly divided into exhaust type, condensation type, and heat pump type. [0003] Exhaust type: The principle is to use electric heating air and blow it into the drum, and use high temperature air to heat the moisture in the clothes, so that it evaporates into water vapor and is discharged with the air. This kind of system has high energy consumption, low efficiency, high noise, and high drying temperature, which will cause great damage to clothes, and is not suitable for some clothes with temperature-sensitive fabrics. An exhaust pipe is needed to discharge the humid air, which has high requirements for the use environmen...
