WIPO Patent Application WO/2024/083077

A1

The present invention relates to the technical field of laundry treatment devices. In particular, provided are a drying air duct assembly and a laundry treatment device comprising same, which aim to solve the problem of the usage experience being affected due to the fact that the temperature in an air duct of an existing drying air duct assembly cannot be accurately acquired. Therefore, the drying air duct assembly in the present invention comprises a shell, a fan, a heating member and a temperature control member, wherein the shell is provided with an air inlet and an air outlet; the fan is configured to be capable of introducing an airflow from the outside of the shell into the shell; the heating member is arranged in the shell and is provided with a heating air duct; the temperature control member is arranged in the heating air duct and is used for measuring the temperature in the heating air duct; and the temperature control member and a heating body are connected in series to form a loop, and when the temperature in the heating air duct is greater than a set temperature, the loop is disconnected. By means of the present invention, the temperature in a heating air duct can be accurately monitored, thereby achieving more accurate high-temperature hot air; moreover, it is possible to prevent the drying air duct assembly from being burnt out due to the temperature in the heating air duct being overly high.
