Door body protection device, dish-washing machine and control method of dish-washing machine

Abstract

The invention discloses a door body protection device, a dish-washing machine and a control method of the dish-washing machine. The door body protection device comprises a frame body, a door body installed on the frame body in an openable and closable mode, a buffer mechanism for door opening buffer, and a detection mechanism used for detecting whether the buffer mechanism is abnormal or not, andthe two ends of the buffer mechanism are connected to the frame body and the door body respectively. The dish washing machine comprises the door body protection device and a main control system, and the main control system is electrically connected with the detection mechanism. The control method comprises the step that the detection mechanism sends a signal to the main control system after detecting that the buffer mechanism is abnormal. The door body protection device is suitable for household appliances such as a dish-washing machine and has universality. The detection mechanism is small insize, simple in structure and sensitive in reaction, the overall size of the device cannot be increased, normal work of household appliances such as the dish washing machine cannot be affected, reaction is conducted only when the buffer mechanism is abnormal, and possible dangers can be further prevented.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a door protection device, a dishwasher and a control method for the dishwasher. Background technique [0002] Dishwasher is a kind of kitchen appliance used for automatically washing tableware, and it is gradually entering more and more ordinary families. Generally, dishwashers have a drying function, so that after the tableware is washed, it can be dried quickly to prevent the growth of bacteria in a humid environment. [0003] General dishwashers require a higher temperature when drying after the washing program is finished. In order to solve the problem of high energy consumption, some models now automatically open the door of the dishwasher to a certain angle after the program is finished. The air exchange realizes the drying treatment of the tableware inside the body, and the hot and humid air can be discharged to achieve a better drying effect. [0004] Whe...
