Utility model content
For addressing the above problem, the utility model provide a kind of energy-conservation, improve the miniature energy-saving dryer of drying efficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of miniature energy-saving dryer, comprise and be provided with the drying cylinder of air inlet and gas outlet and to the heat pump unit of carrying heated dry air in drying cylinder, heat pump unit comprises regenerator and by compressor, evaporimeter, expansion valve and the condenser refrigeration system loop forming of connecting successively, and by gas outlet draw and the hot junction of the cold junction of the regenerator of flowing through successively, evaporimeter, regenerator, condenser after access the gas transmission air channel of air inlet, gas transmission is provided with circulating fan in air channel.
Be further used as the improvement of technical solutions of the utility model, drying cylinder comprises casing cylinder, is inlaid in the cover plate of the inner bag cylinder of casing cylinder inside and the upper port of closure cylindrical shell and inner bag cylinder, between inner bag cylinder and casing cylinder, form hydrofuge gap, the sidewall of inner bag cylinder is provided with the weep hole in some conducting inner bag drum cavities and hydrofuge gap, gas outlet be located at casing cylinder and with the conducting of hydrofuge gap, air inlet is located at inner bag cylinder the inner chamber conducting with inner bag cylinder.
Be further used as the improvement of technical solutions of the utility model, air inlet is introduced inner bag cylinder by a jet pipe, and jet pipe is probeed into the inner chamber of inner bag cylinder by the axis of inner bag cylinder, and along the outer wall of jet pipe body, some pores is set.
Be further used as the improvement of technical solutions of the utility model, in inner bag cylinder, be provided with multilayer clothing dividing plate.
The beneficial effects of the utility model: in this miniature energy-saving dryer, after clothing is inserted in drying cylinder, start heat pump unit and circulating fan, after blasting the air of drying cylinder and contact with clothing by air inlet, take out of after the moisture of clothing, flow into gas transmission air channel from gas outlet, then by delivering to drying cylinder circulating dehumidification after heat pump unit dehumidifying heating.The utility model, by circulating with the air circulation of clothing heat exchange, ensures making full use of of air heat energy, avoids energy loss.In addition, this dryer, on the heat pump basis being made up of compressor, evaporimeter, expansion valve and condenser, adds regenerator, and regenerator and heat pump complement each other, and reach energy-conservation object together with circulation gas transmission air channel, improve drying efficiency by improving the thermal efficiency.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model example structure schematic diagram.
