Drying machine adopting freezing circulatory system

Abstract

The invention discloses a drying machine with cooling cycle system, which comprises: a rolling drum, a circulation pipe, a fan, an electric heater, a cooling cycle system, a out-gas inflow pipe connected with circulation pipe to make outer air flow said system, and a bypass pipe arranged on circulation pipe to make air from the drum do not pass evaporator and consender to return directly to said drum. This invention reduces coolant temperature, prevents over loading and interruption of drying, and increases drying efficiency.

Description

Technical field [0001] The invention relates to a dryer, in particular to a dryer adopting a refrigeration cycle system. Background technique [0002] As we all know, a dryer is a household appliance that uses a fan to forcibly suck in air from the outside and heat it with an electric heater, and then blow the heated high-temperature air into the drum to dry the laundry. [0003] More specifically, the working principle of the dryer is to use a fan and an electric heater on the circulation channel connected to the drum to forcibly suck in air and heat the sucked air, and then deliver the heated high-temperature air to the inside of the drum. The laundry is dried, and then the air in the drum is circulated through the circulation channel and reheated. The heated high-temperature air is transported to the inside of the drum to dry the laundry, and the cycle continues until the laundry is dried. [0004] In the drying process of the above-mentioned existing ordinary dryer, the air d...

Problems solved by technology

[0023] However, during the drying operation of the dryer, if the compressor 31 is overloaded due to an increase in the temperature or pressure of the refrigerant, the refrigeration cycle system 30 will stop operating, and then wait until the temperature or pressure of the refrigerant drops to cause compression. It takes a long time to restart the machine 31, resulting in prolonged drying time and reduced drying efficiency; and the compressor 31 also shortens its service life due to excessive frequent starts.
