AI Technical Summary

Technical Problem

Conventional washing machines suffer from poor ventilation effects due to the intake and exhaust ports of the fresh air system being on the same plate, leading to recirculation of humid air and decreased effectiveness.

Method used

The fresh-air washing machine design features an air intake and outlet on the same plate, forming an angle of 60 to 120 degrees, with both ports located on the back plate, utilizing a fan assembly and ducts to circulate fresh air and prevent recirculation, and integrates a heat pump-type drying system to enhance ventilation and drying efficiency.

Benefits of technology

This design improves ventilation by preventing recirculation of humid air, maintains cleanliness, and simplifies the structure by eliminating the need for additional drive units, thereby enhancing user experience and reducing costs.

Abstract

The present invention relates to the technical field of washing machines, and specifically aims to provide a fresh air washing machine to solve the problem of poor ventilation effect inside conventional washing machines. For this purpose, the fresh air washing machine of the present invention includes a housing, a cylinder body and a fan assembly mounted inside the housing. The fresh air washing machine further includes a fresh air system for supplying fresh air to the cylinder body. The housing is provided with an air inlet and an air outlet. The fresh air system supplies fresh air into the cylinder body through the air inlet and discharges the air inside the cylinder body through the air outlet. The air outlet and the air inlet are provided adjacent to each other, and the air outlet and the air inlet form an angle that opens from the inside to the outside. The high-humidity air flow flowing out from the air outlet flows in a direction away from the air inlet, and fresh air is sucked into the air inlet from a direction away from the air outlet. Since the air flows in both are far apart, it is possible to avoid the high-humidity air flowing out from the air outlet from re-entering the inside of the cylinder body through the air inlet, which is advantageous for improving the ventilation effect of the fresh air system.
