摘要： An air conditioner includes an outdoor unit, at least one indoor unit and a compressor. The outdoor unit is connected to the indoor unit by a refrigerant pipe to form a closed circuit. The refrigerant pipe is divided into high and low pressure pipes. The air conditioner further includes a refrigerant leakage detecting unit provided on the indoor unit to detect refrigerant leakage, a high pressure pipe shutoff valve provided on the high pressure pipe of the refrigerant pipe, and a low pressure pipe shutoff valve provided on the low pressure pipe of the refrigerant pipe. Refrigerant is restored into the outdoor unit by closing the high pressure pipe shutoff valve and opening the low pressure pipe shutoff valve.

摘要： A clothes washing machine includes a water tub, a spin basket, and a clothes agitator. A vertical dehydrating shaft is fixed to the spin basket, and a laundering shaft extends coaxially within the dehydrating shaft. Upper and lower ends of the laundering shaft are connected to the agitator and a motor respectively, whereby rotation of the motor is always transmitted to the agitator. In order to selectively connect the dehydrating shaft to the laundering shaft (e.g., during a spin-drying operation), a connecting gear is mounted on the dehydrating shaft for rotation therewith and for vertical movement relative thereto. A power-driven actuator is provided for selectively moving the connecting gear up or down. When the connecting gear moves down, lower teeth thereon become operably connected to the motor so that the dehydrating shaft and laundering shaft rotate together. During a washing or rinsing operation, the connecting gear is moved up, whereby upper teeth thereon become connected to a fixed element, whereby the dehydrating shaft is fixed against rotation.
