Door lock structure and door locking method

Abstract

The invention discloses a door lock structure, a door locking method employing the door lock structure and a clothes dryer with the door lock structure. The door lock structure comprises a lock body and a door hook which are matched to lock. A door hook locking portion is arranged on the lock body and used for locking the door hook. A door hook locking portion adjustment device is arranged on the lock body and used for adjusting locking force of the door hook locking portion. The door lock structure is simple in structure, convenient to mount and convenient for adjusting the locking force required in locking. Due to tiredness of a spring within a long time of use, poor locking force easily happens, with adjustment of an adjusting bolt, the adjustment of the locking force is realized, thus the door lock structure is convenient to maintain. Compared with the conventional plastic materials, with metal materials adopted as components, the door lock is good in heat-resistant quality.

Description

technical field [0001] The invention relates to a lock, in particular to a mechanical door lock structure and a door locking method applied to household appliances. Background technique [0002] Household appliances such as washing machines and clothes dryers usually need to be equipped with door locks in order to prevent their doors from opening automatically during operation. When it is running, it will not open by itself, causing safety hazards and affecting normal operation. [0003] Existing door lock devices usually have two types: electric type and mechanical type. The electric type door lock has a complex structure and usually needs to provide a certain amount of power during the process of opening and closing. It cannot be operated when the power is cut off, which affects the use. [0004] The current mechanical door lock structure usually includes a door hook locking part and a door hook. The door hook locking part has a moving part that cooperates with the door h...

Problems solved by technology

[0006] In the above-mentioned patent documents, a spring and a lock are fixed in the space formed by the fixed connection between the latch body and the latch cover, and the lock is pushed by the spring to lock the hook to lock the door body and the main body of the dryer. However, the above structure The assembly of the middle door lock is complicated and time-consuming. The latch body and the latch cover are snap-fitted. The original door lock needs to be destroyed during maintenance and door reversing. The maintenance time is long and the maintenance cost is high. The force required to open the door The size of the door cannot be effectively controlled, and it is easy to cause the door to be difficult to open or easy to open by itself

[0007] In addition, most of the existing dryer door locks are of plastic structure, which cannot withstand the high temperature test of the dryer in the combustion test, and may easily cause the door lock to fail, resulting in failure of the combustion test
