Tubeless portable air conditioner

Abstract

This invention discloses a ductless portable air conditioner, comprising a housing, a fan, a condenser assembly, a water storage device, a spray assembly, and a water-spinning assembly. The housing has a mounting cavity, and an air inlet and an air outlet connected to the mounting cavity. The air inlet of the fan is connected to the air inlet, and the air outlet of the fan is connected to the air outlet. The condenser assembly is located between the fan and the air outlet. The water storage device can collect water dripping from the surface of the condenser, and the spray assembly can spray the water in the water storage device onto the condenser assembly. The water-spinning assembly is located in the water storage device and can swing the water in the water storage device upwards onto the condenser assembly. This provides a highly efficient cooling effect on the condenser, ensuring that the temperature of the air flowing through the condenser and exiting from the first air outlet reaches a preset value. Therefore, there is no need to install an exhaust duct to exhaust the air outdoors, allowing the user to directly move the portable air conditioner, thus optimizing the user experience.
