Vertical humidifier with variable-diameter evaporator

Abstract

The invention discloses a vertical humidifier with a variable-diameter evaporator, and belongs to an evaporative humidifier. The humidifier comprises a housing, wherein an evaporating water tank is arranged in the housing, an evaporator is arranged in the evaporating water tank, a fan is installed below the evaporator, and the air inlet end of the fan communicates with an air inlet of the housing;a water storage tank is further installed on the upper part of the evaporating water tank, the evaporator surrounds the lower part of the water storage tank, and the water storage tank further communicates with the evaporating water tank through a water inlet; and an air outlet is formed in the upper part of the housing, the air outlet communicates with the air outlet end of the fan, and the evaporator is arranged in an airflow channel between the air outlet and the air outlet end of the fan. The fan is installed on the lower part of the evaporator, so that operating noise waves pass throughthe evaporator and are reduced, and silence is realized; the turbulence and mass transfer effects of airflow can be increased by the variable-diameter evaporator with a tight lower end and a loose upper end, so that the humidification amount is effectively increased; and additionally, a vertical compact product structure surrounded by the variable-diameter evaporator is adopted, so that the size of the evaporator is smaller.

Description

technical field [0001] The present invention relates to an evaporative humidifier, more specifically, the present invention mainly relates to a vertical humidifier with a variable-diameter evaporator. Background technique [0002] The evaporative humidifier uses a fan to generate airflow. When the airflow passes through the evaporator, the water molecules attached to the evaporator evaporate and are discharged together with the airflow, thereby keeping the indoor air humid. Since the fan needs to be driven by a motor, and the fan is installed above the casing of the humidifier, the rotation of the fan creates negative pressure in the casing to generate airflow, but the operation of the motor will also generate noise at the same time, which puts forward a challenge to the sealing of the humidifier casing. At the same time, considering the noise problem, the fan speed is limited, which in turn limits the maximum humidification capacity of the humidifier. And most of the humid...
