Air channel assembly with through-flow air wheel, and tower fan

Abstract

The invention discloses an air channel assembly with a through-flow air wheel, and a tower fan provided with the air channel assembly. The through-flow air wheel is arranged inside the air channel assembly; an air channel air inlet and an air channel air outlet are formed in the air channel assembly; the radial outer edges of the air channel air outlet, the air channel air inlet and the air channel assembly are located on the same circumference face; an air outlet grille is arranged at the air channel air outlet; and the radial outer edge of the air outlet grille is located on the circumference face. In the air channel assembly with the through-flow air wheel, and the tower fan, the radial outer edge of the air outlet grille is located on the circumference face of the radial outer edge ofthe air channel assembly; the radius of the air outlet face of the air outlet grille is equal to the radius of an inner rotor of the tower fan, and therefore interference of the air outlet griller anda shell of the tower fan can be avoided during rotating of the inner rotor; and in this way, the rotating range of the inner rotor can be enlarged, the air-swept range is enlarged, and 360-degree airsupply can be achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air duct assembly of a cross-flow wind wheel and a tower fan provided with the air duct assembly and the cross-flow wind wheel. Background technique [0002] Existing tower fan products generally use a cross-flow air duct structure, and a grille is designed at the air outlet to guide the air flow, so that the air is more uniform in the horizontal range of the air outlet. There is a relatively large distance between the air inlet surface of the existing outlet grille and the cross-flow fan wheel, which makes the outlet air flow deflected; or the distance between the outlet grille and the cross-flow fan wheel is short but the flow path formed by the grille is too large. Long, high grille wind resistance, low fan efficiency, and when the tower fan is an internal rotation structure, the cross-flow air duct can rotate inside the tower fan alone, and the grille is easy to i...

Problems solved by technology

There is a relatively large distance between the air inlet surface of the existing outlet grille and the cross-flow fan wheel, which makes the outlet air flow deflected; or the distance between the outlet grille and the cross-flow fan wheel is short but the flow path formed by the grille is too large. Long, high grille wind resistance, low fan efficiency, and when the tower fan is an internal rotation structure, the cross-flow air duct can rotate inside the tower fan alone, and the grille is easy to interfere with the tower fan shell, making the sweeping range relatively small , as attached Figure 2-3 shown
