Heat-exchange system with waste heat recovery function for dry clothes condensation and cloths dryer

Abstract

The invention discloses a heat-exchange system with the waste heat recovery function for dry clothes condensation and a clothes dryer. The heat-exchange system comprises a waste heat recovery device, a condenser and a water-collecting box, wherein the waste heat recovery device comprises two groups of airflow air ways, i.e. a damp and hot-air air way and a waste heat recovery air way; the two groups of airflow air ways form a heat-exchange structure; and damp and hot air passes through the damp and hot-air air way of the waste heat recovery device, the condenser and the water-collecting box in sequence and then passes through the waste heat recovery air way of the waste heat recovery device to finish water heat recovery. An air outlet of the clothes dryer is communicated with the damp and hot-air air way of the waste heat recovery device through an air outlet duct and is then communicated with an air inlet through an air inlet duct after the damp and hot air passes through the condenser and the water-collecting box in sequence and then passes through the waste heat recovery air way of the waste heat recovery device to finish the waste heat recovery; a filter is arranged in the air inlet duct; and a drying fan and a heating device are arranged in the air inlet duct. The heat-exchange system has the beneficial effect that the electric energy and the time are saved by utilizing waste heat, and the clothes drying efficiency is improved.

Description

technical field [0001] The invention relates to a clothes dryer and a clothes drying system, in particular to a heat exchange system for condensation of clothes drying and a clothes dryer with the function of recovering waste heat. Background technique [0002] In a drying mechanism used in a clothes dryer or a washer-dryer, a device for generating heated air often adopts a heating method in which air is heated by a heater. Existing electric heating dryers generally use heating wires or heating tubes as the heat source. Such products have high energy consumption, long drying time and poor safety. In order to reduce energy consumption, a heat pump dryer has been developed, which uses a heat pump system to strengthen the recycling of heat, improve heat utilization efficiency, and reduce power consumption. [0003] The heat pump clothes drying device is provided with the following air circulation channels: the heated air heated by the condenser in the heat pump cycle system is...

Problems solved by technology

The disadvantage of the latter is that when the dry air is discharged to the outside, the water vapor in the humid air cannot be completely condensed out, and a large amount of water vapor still enters the environment and affects the comfort of the environment.
