Washing and drying integrated machine for washing clothes by adopting water heated by heat pump

Abstract

The invention discloses a washing and drying integrated machine for washing clothes by adopting water heated by a heat pump. The washing and drying integrated machine comprises an outer barrel, an inner barrel, a heat pump system and a water inlet pipeline; the inner barrel is arranged in the outer barrel; the outer barrel and the inner barrel are coaxially arranged; the heat pump system comprises an evaporator, a compressor, a two-position three-way electromagnetic valve, a condenser bank and a throttling valve, wherein the condenser bank is formed by connecting an air-cooled condenser and a water-cooled condenser in parallel; the evaporator, the compressor, the two-position three-way electromagnetic valve, the condenser bank, the throttling valve and the evaporator are connected in series to form a circulating system; the water inlet pipeline, the heat pump system and the outer barrel form a water heating system; the outer barrel is connected with the heat pump system through two sections of air flues to form a drying and circulating air path for drying the clothes; and the two-position three-way electromagnetic valve is used for switching and controlling a refrigerant through the air-cooled condenser or the water-cooled condenser to realize the cloth drying or water heating function of the washing and drying integrated machine. Besides the functions of drying the clothes and heating the water, cooling and dehumidifying functions, heating and dehumidifying functions and the like can be provided by arranging a switching mechanism and an external air inlet / outlet in the air path.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine equipped with a heat pump system capable of drying clothes, especially an integrated washing and drying machine using a heat pump to prepare hot water for laundry. Background technique [0002] For washing machines with hot water washing function, the washing water is generally heated to 40°C or above. At present, electric heating is used to control hot water. The heat energy of hot water is all derived from the electric energy consumed by the heating pipe, and the heating efficiency is low. , power consumption is large, how to reduce power consumption has always been a concern of people. [0003] Existing drum-type washing machines using hot water washing, the working process is as follows: choose hot water washing, set the water temperature to 40°C, open the water inlet valve, the water passes through the water valve, the washing powder (agent) box flows into the drum, and...

Problems solved by technology

In addition, heating with a heating tube will increase two hidden dangers. One is that the heating tube will cause dry burning when the water level sensor and temperature protection fail, resulting in accidental fire; the other is that the shell of the heating tube is broken and water invades the heating tube. Heating wire part, causing current leakage and endangering personal safety
