Description
Technical Field
[0001] The utility model relates to the technical field of the limit structure of a clothes dryer, and more specifically to a scroll limit structure. Background Art
[0002] At present, as an intelligent household appliance integrating lifting, lighting, drying, sterilization and artistic decoration, an electric clothes dryer is deeply loved by consumers. The electric clothes dryer includes a main machine component installed on the ceiling and a clothes drying rack located below the main machine component. A power assembly is arranged inside the main machine component. Generally, a motor is used as the power source of the clothes dryer, and a steel wire rope is used as the traction medium. One end of the steel wire rope is fixed on a winding wheel inside the motor, and the other end is fixed on the clothes drying rack. By rotating the motor, the winding wheel is further driven to rotate, so as to drive the steel wire rope to traction the clothes drying rack to move up and down.
[0003] The up and down limit protection devices in the motor part directly affect the normal use of the electric clothes dryer. In the existing motor control system, there are two limit methods: electronic limit and mechanical limit. The electronic limit controls the up and down limits of the clothes dryer through a program. After long-term use, it is easy to be inaccurate due to various external factors and its own wear and other reasons, resulting in the phenomenon of limit deviation. The mechanical limit controls the up and down limits through a micro switch, usually installed at the side plate position. The up and down limits are controlled by the scissors rack touching the micro switch, but the mechanical limit structure on the side plate is usually difficult to install. Therefore, a limit structure with convenient installation, simple structure and high precision is needed. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a scroll limit structure. The overall structure of the scroll limit structure is simple, the installation is convenient, the limit precision is high, and it is not easy to be inaccurate due to various external factors and its own wear and other reasons after long-term use, and the phenomenon of limit deviation can be avoided.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A scroll limit structure includes a winding wheel, a sliding piece and a micro switch. A scroll groove is arranged at one end of the winding wheel. A sliding limit structure is slidably connected to the sliding piece. The micro switch is located on one side of the winding wheel, and the contact end of the micro switch faces the sliding piece. A driving plate is arranged on one side of the sliding piece, and the driving plate extends into the scroll groove and cooperates with the scroll groove. When the winding wheel rotates, the sliding piece can be driven to move towards or away from the micro switch under the action of the scroll groove and the sliding limit structure.
[0007] Further, the sliding piece is in the shape of a waist-shaped circular ring, and a guide chute is arranged inside the sliding piece. The sliding limit structure includes a limit fixing block, which is fixedly arranged and extends into the guide chute.
[0008] Further, a contact piece is arranged on one side of the sliding piece facing the microswitch, and the contact piece can contact the contact end of the microswitch.
[0009] Further, a chamber is arranged at the end of the wire reel, and the scroll groove is located at the bottom of the chamber.
[0010] Further, the wire reel includes a transmission gear and a wire winding sleeve. A wire winding groove is arranged on the wire winding sleeve, and the chamber is located at one end of the transmission gear away from the wire winding sleeve.
[0011] Further, a wire rope connection structure is arranged on the wire winding sleeve.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] By arranging a wire reel, a sliding piece, a sliding limit structure and a microswitch, and arranging a scroll groove on the wire reel, when the wire reel rotates, the sliding piece can be driven to move towards or away from the microswitch through the action of the scroll groove and the sliding limit structure, thereby controlling and limiting the extreme position of the wire rope.
