The utility model is preferred, and described lower air duct cover plate is installed on the roof of inner container of icebox, and described inner container of icebox, upper air duct cover plate and lower air duct cover plate are in conjunction with forming the air channel, and described centrifugal blower is positioned at the top of the roof of inner container of icebox.
The utility model is preferred, and described lower air duct cover plate is rectangular-shaped.
The lower air duct cover plate is arranged to vertical configuration, meets air-flow under the effect of centrifugal blower, be vertical characteristics to flowing, thereby can further avoid the impact of air-flow.
The utility model is preferred, and described centrifugal blower is connected on the described lower air duct cover plate, and described lower air duct cover plate is installed by screw and the mode of buckle engaging is installed on the described inner container of icebox.
The lower air duct cover plate has reduced number of parts by being installed in structure on the inner container of icebox with the centrifugal blower clamping and by the mode that screw is installed and buckle engages, and has simplified mounting process, is beneficial to installation.
The utility model is preferred, also comprise the spiral case ducting assembly, described spiral case ducting assembly comprises spiral case and the spiral case base that is arranged on the described lower air duct cover plate, described spiral case engages up and down formation spiral case air channel with the spiral case base, described spiral case air channel is being gradually large opening shape of cross section to the air outlet bearing of trend, described centrifugal blower is installed in the described spiral case air channel.
Adopt the structure in spiral case air channel, have to increase and wind pressure, overcome the effect of SR, can improve the cycle efficieny of air-flow, reduce flow losses, reduce energy consumption and reduce the noise of refrigerator complete machine.
The utility model is preferred, and described centrifugal blower is installed on the described spiral case.
Centrifugal blower is installed on the spiral case, can carries out modularization and install, thereby optimize mounting process.
The utility model is preferred, also comprises temperature sensor, and described temperature sensor is installed on the described lower air duct cover plate.
The structure of the air circulating system of refrigerator of the present utility model by using centrifugal blower and adopting the spiral case air channel structure, makes air-flow can not cause to the inner bag of refrigerator direct impact, thus larger vibration and noise in the time of can effectively avoiding airflow circulating.Have again, by centrifugal blower is connected on the lower air duct cover plate, and the lower air duct cover plate is installed on the inner container of icebox by the mode that screw is installed and buckle engages, thereby simplified mounting process, be beneficial to installation.
