Embodiment 1

[0034] Such as Figure 1-Figure 4 As shown, a kind of automatic double door opening device of the present embodiment includes a power motor 200, a transmission gear set, a transmission rack and a door opening gear set. Each side is respectively provided with a set of matching transmission gear set and door opening gear set, and the transmission gear set is connected with the door opening gear set through the transmission rack; Drive teeth 212, single door drive teeth 211 are used for meshing transmission with a transmission gear set on one side, and double door drive teeth 212 are used for meshing transmission with the transmission gear sets on both sides at the same time; The door body structure corresponding to one side is connected to control the opening of the door body.

[0035] In this embodiment, the transmission gear set includes a transmission gear and a directional transmission gear. The transmission gear and the directional transmission gear are coaxially distribut...

Embodiment 2

[0049] A kind of automatic double-door refrigerator of this embodiment adopts the automatic double-door device described in the above-mentioned embodiment, and the top of the hinge side of the left door body 102 of the refrigerator is connected with the left door gear 304 through the connecting arm 103, and the right door body The hinge side top of 100 is connected with right door opening gear 405 by connecting arm 101 . The opening and closing action of the door body can be controlled by controlling the rotation state of the connecting arm 103 and the connecting arm 101 .

[0050] In this embodiment, both ends of the left rack 302 and the right rack 402 are respectively provided with return springs; Return springs are arranged between the side walls of the refrigerator. After the door opening action is completed, the return spring helps to realize the automatic and gentle door closing action.

[0051] In this embodiment, the non-toothed back sides of the left rack 302 and t...

Abstract

The invention discloses an automatic double-door refrigerator and a double-door device thereof, belonging to the field of refrigerators. An automatic double door opening device of the present invention comprises a power motor, a transmission gear set, a transmission rack and a door opening gear set, the output end of the power motor is connected with incomplete gears, and a set of matching gears are respectively arranged on both sides of the power motor. The transmission gear set and the door opening gear set, the transmission gear set is connected to the door opening gear set through the transmission rack; the two sides of the incomplete gear are respectively provided with a single door drive tooth and a double door drive tooth, and the single door drive tooth is used to communicate with a certain door. A unilateral transmission gear set is meshed for transmission, and the double gate drive teeth are used for simultaneous meshing and transmission with the transmission gear sets on both sides. The invention overcomes the inconvenience of automatically opening and closing the doors of double-door refrigerators in the prior art, uses a single drive mechanism to realize the functions of simultaneous opening of both doors and independent opening of a single door, and makes the use of the refrigerator with the double-door device more convenient.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to an automatic double-door refrigerator and a double-door device. Background technique [0002] At present, mid-to-high-end refrigerators on the market are relatively large, and the door body, the weight of its load, and the suction force of the door body or the door seal of the drawer-type door body are relatively large. More and more users report that the refrigerator door body is not easy to open. In response to this problem, electric opening devices have appeared in the industry at present, which mainly control the opening and closing of the door body through the motor drive. The motor usually only rotates clockwise and counterclockwise. When two doors are opened at the same time or the left and right doors are opened separately, the conventional electric opening mechanism is still difficult to meet the needs of use. How to use a single drive to realize the flexible and a...
