Abstract: The heat pump system and the electrical heating system of a clothes dryer are controlled to work cooperatively, thus allowing the clothes dryer to at least comprise a fast mode in which the electrical heating pipe of the heating system is turned on after the compressor of the heat pump system is turned on and operated stably. Air about to enter the clothes drying drum is controlled to be firstly heated by the condenser of the heat pump system and further heated by the electrical heating pipe, and then to enter the clothes drying drum, and the load of the heat pump system is reduced in an auxiliary condensing manner, when the load of the heat pump system is close to the maximum load. Therefore, simultaneous working of the electrical heating system and the heat pump system is ensured, and the clothes drying speed is improved.

Abstract: A washing method and a washing machine using the washing method. In the washing method, washings are suspended in a washing space through a suspension component, so that the washings can move in a first movement manner in the washing space; the washings are washed through a water flow sprayed by nozzles which move in a second movement manner different from the first movement manner; and the water flow are made to cover at least part of washings by changing a relative position between washings and the nozzles.

Abstract: A heat pump clothes dryer comprising a circulating air path consisting of a drying drum and a drying air path for circularly flowing drying air; and a heat pump system consisting of an evaporator, a throttling device, a condenser and a compressor successively connected end to end for circularly flowing a refrigerant medium. The condenser and the evaporator are disposed on the drying air path, and perform heat exchange with the drying air. The compressor has independent suction compression chambers, each suction compression chamber being switchably connected in series or in parallel. When the dryer starts drying in a low-temperature environment, the suction compression chambers of the compressor operate in a parallel state, so that the air displacement of the compressor is increased to improve the flowing activity of the refrigerant medium in the heat pump system, so as to avoid occurrence of frosting of the evaporator.

Abstract: Disclosed are an impeller-type heat pump integrated washer-dryer and a drying method. The impeller-type heat pump integrated washer-dryer includes: a housing, an outer drum mounted inside the housing, an inner drum mounted in the outer drum, an impeller provided at the bottom of the inner drum, and an electric motor provided at the lower part of the outer drum for driving of the inner drum and/or the pulsator. An outer part of the outer drum is provided with an air duct and a heat pump system. The air duct communicates with sealed top and bottom ends of the outer drum. The heat pump system has an evaporator and a condenser mounted in the air duct, a throttle apparatus and a compressor. The evaporator, the compressor, the condenser and the throttle apparatus are sequentially connected in succession to form a circulating flow path enabling a medium to flow.

Abstract: The present invention relates to a control method for a laundry dryer. The laundry dryer is a heat-pump type laundry dryer and a compressor of the laundry dryer is a variable-frequency compressor. The control method includes setting a minimum running frequency of the compressor according to an amount of clothes to be dried, where the more the clothes are, the larger the set minimum running frequency is. Specifically, when laundry drying is started, the amount of the clothes being dried is detected. According to the detected information, a minimum running frequency of the compressor, corresponding to the information, is invoked, and the minimum running frequency of the compressor in the current laundry drying process is set.
