Door opening and closing device and household appliance
The invention relates to the technical field of electric appliances, and discloses a door opening and closing device and a household appliance. The door opening and closing device comprises a rotating mechanism and a power assisting mechanism, the rotating mechanism comprises a first driving unit, a first gear set and a connecting rod mechanism, the first gear set is connected with a door body of the household appliance through the connecting rod mechanism, and the first driving unit is used for driving the first gear set to rotate forwards and backwards so as to open and close the door body. The power assisting mechanism comprises a second driving unit, a second clutch unit and a second gear set, the second gear set is meshed with the first gear set, and the second driving unit drives the second gear set to rotate forwards and backwards through the second clutch unit so as to assist opening and closing of the door body. A door ejecting mechanism in structural forms such as a rack push rod is omitted, the size is small, the cost is low, the process is simple, operation is stable, noise is low, and the abnormal conditions such as blockage, abnormal sound or untight door body closing are effectively avoided.
本发明涉及电器技术领域，公开一种开关门装置及家用电器。所述开关门装置包括旋转机构和助力机构，旋转机构包括第一驱动单元、第一齿轮组和连杆机构，第一齿轮组通过连杆机构与家用电器的门体连接，第一驱动单元用于驱动第一齿轮组正反转，以启闭门体，助力机构包括第二驱动单元、第二离合单元和第二齿轮组，第二齿轮组与第一齿轮组啮合，第二驱动单元通过第二离合单元驱动第二齿轮组正反转，以助力门体的启闭。本发明取消了齿条推杆等结构形式的顶门机构，体积小，成本低，工艺简单，运行稳定，噪音低，有效避免了卡顿、异响或门体关闭不严等异常情况。
