Problems solved by technology

On the other hand, when a large amount of food is stored in the door pocket and the door is heavy, the time required for acceleration increases due to the high inertia of the door, and the maximum speed of the door becomes small, so the door opening action is at a low speed.
Therefore, the acceleration varies depending on the amount of food stored in the door pocket, and especially when the amount of food stored is small, the door opening action is sharp, and, due to the short-term acceleration during the door opening action, there is a possibility that an impact force may be applied to the food. topic

Abstract

The invention provides a door opener capable of electrically opening a rotary door without generating an abrupt impression, thus smoothly opening the door; a refrigerator comprises a first door (2a) and a second door (2b) respectively supported by a rotary pivot, the door opener (60) opening the first and second doors and provided with a motor (82) capable of making forward rotating and backward rotation, a transmission unit (83) transmitting rotation of the motor (82), a switching unit (80) carrying out switching motions of a transmitted target of the transmission unit according to the forward rotation and backward rotation of the motor (82), a first door opening unit (61a) transmitting driving force and opening the first door (2a) when the switching unit switches to one party, and a second door opening unit (61b) transmitting driving force and opening the second door (2b) when the switching unit switches to the other party.

Description

technical field [0001] The present invention relates to a door opening device and a refrigerator provided with the door opening device. Background technique [0002] In the first solution of the patent document, "a motion assisting device is disclosed, which is characterized in that it has a transmission gear that can rotate according to the driving force of the motor, and can advance alternately in accordance with the rotation direction of the transmission gear, and can directly or indirectly The first and second protruding members contacting the first and second opening and closing members rotate the transmission gear in the first direction to advance the first protruding member to assist the movement of the first opening and closing member. Furthermore, by rotating the transmission gear in a second direction opposite to the first direction, the second protruding member is advanced to assist the operation of the second opening and closing member”. [0003] In the second p...
