Abstract: An impeller mounting structure of air conditioning device is provided, including an electric machine arranged between a condenser and an evaporator and a condenser impeller and an evaporator impeller. The electric machine is mounted to an air duct casing of the condenser. The condenser impeller and the evaporator impeller are mounted to a shaft of the electric machine at the same side of the electric machine. A central air duct casing is arranged between the condenser impeller and the evaporator impeller. The evaporator impeller is mounted inside the evaporator air duct casing. The condenser impeller and the evaporator impeller are provided with mated self-locking structures. The mounting structure provides the efficacies that the impeller mounting structure of air conditioning device makes the manufacturing and assembling simplified, the size of a movable air conditioning device reduced, balance of electric machine in operation enhanced, and the number of parts assembled reduced.

Abstract: A condensed water utilization structure is provided for an air conditioning device and includes a driving electric machine, a transmission mechanism coupled to the driving electric machine, a water pumping device, a water spraying tray, and a water collection tray positioned below the water spraying tray. The water pumping device includes a cylinder forming therein a water inlet chamber, a water outlet chamber, and a piston chamber. The piston chamber receives therein a piston coupled to the transmission mechanism. The water inlet chamber and the piston chamber communicate each other through a water inlet piston, and the water outlet chamber and the piston chamber communicate each other through a water outlet piston. The water inlet chamber has a water inlet port in communication with the water collection tray. The water outlet chamber has a water outlet port in communication with the water spraying tray through a pipe.

Abstract: A roller evaporator for a snow machine includes an inner layer and an outer layer. The inner layer is fixed on a high pressure tube and a low pressure tube, and the outer layer corresponds to and rotates relatively with respect to the inner layer. A roller of the roller evaporator is divided into two layers, with the inner layer being installed and sealed on the high pressure tube. Therefore, an extremely good sealing effect is provided and refrigerant does leak out easily while making ice.

Abstract: The present invention discloses an exhaust pipe of an air conditioner. The air conditioner includes a condenser, a first pipe, an air duct and a second pipe. The condenser is located in the air conditioner, an end of the first pipe is close to the condenser, the other end is penetrated out of a side of the condenser, and an interior of the first pipe is provided with the second pipe. An end of the second pipe is connected with the air duct (the air duct is located in the air conditioner), and the other end is penetrated out of the first pipe. Therefore, when the air conditioner is running, hot air is sucked into the condenser through the first pipe and then the circulated hot air is sent out of a room from the second pipe through the air duct, such that indoor temperature can be reduced effectively.

Abstract: A hiding structure of a vent pipe for a mobile air conditioner is composed of a housing, a cold air outlet for blowing the cold air into a room, and a hot air outlet for expelling the hot air out of the room. The hot air outlet is disposed with an extractable vent pipe which is collected in the housing of the mobile air conditioner, the housing is disposed with a connector opening from which the vent pipe can be extended, and the connector opening is disposed with a vent pipe cap. As the extractable vent pipe is used by the present invention, a volume of the mobile air conditioner is decreased, and convenience in moving is increased.
