Lifting device and washing machine having same

A lifting device and a washing machine having same that resolves difficulty moving existing washing machines. The lifting device includes a driving device, a first lever, a second lever and support feet; the driving device is provided at the bottom of a washing machine body; the support feet are movably provided, in a vertical direction, at the bottom of the body; a first end of the first lever is pivotally connected to the driving device, a second end of the first lever is pivotally connected to one support foot, and a pivoting end of the first lever is pivotally connected to the body; a first end of the second lever is pivotally connected to the driving device, a second end of the second lever is pivotally connected to one support foot, and a pivoting end of the second lever is pivotally connected to the body.

A vented heat pump dryer, comprising: an outer drum, an air-intake drying air duct and an air-exhaust drying air duct for allowing communicating the outer drum with outside respectively. The dryer is also provided with a heat pump system. A condenser of the heat pump system is arranged in the air-intake drying air duct, and an evaporator is arranged in the air-exhaust drying air duct. The air-exhaust drying air duct comprises at least two branches capable of being controlled to open and close. Each branch is provided with a corresponding evaporator. At different drying stage, the dryer makes exhaust air stream flow through different branches independently or at the same time, so that can adjust the working states of the heat pump reasonably and increase the drying efficiency of the dryer.

Vented heat pump dryer

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.

A filter system with self-cleaning function and a clothes dryer using the filter system, wherein the filter system comprises a shellwith an air inletand an air outlet, a filter system screen, a cleaning unit, a driving device and a lint collection drawer, wherein the driving device includes a drive motordisposed on the outer wall of the shelland a screw roddisposed inside the shell, the output shaft of the drive motorpasses through the small hole Iopened on the shelland extends inside the shell; one end of the screw rodis engaged with the output shaft of the drive motorand the other end of the screw rodis mounted inside the small hole IIopened on the wall of the shellopposite to the output shaft of the drive motor. The cleaning unitis screwed on the screw rodand driven by the screw rodto move back and forth and the lower end of the cleaning unitis in contact with the filter system screen, and the automatic self-cleaning lint function could be achieved. For the clothes dryer, the overall structure becomes more compact and reliable by improving structure of the filter system, and the lint collection efficiency and also drying efficiency are increased.

Filtering system with self-cleaning function and clothes dryer

A method for controlling an expansion valve of a frequency conversion heat pump clothes dryer. The open degree of the valve is adjusted through parameters such as the operation time/power/current at a frequency of the frequency conversion compressor; a reference value of the operation time/power/current at a certain frequency is set, and compared with an actual value of the operation time/power/current at the certain frequency of the compressor; if the actual value of the operation time is less than the set reference value or the actual value of the power/current is greater than the reference value, the open degree of the expansion value is increased; and if the actual value of the operation time is greater than the set reference value or the actual value of the power/current is less than the set reference value, the open degree of the expansion valve is decreased.

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.

Control method for clothes dryer, and clothes dryer

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.
