Embodiment Construction
[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0045] See attached Figures 1 to 7 , an automatic door opening device of the present invention, comprising a motor 1, a worm gear transmission mechanism, a gear transmission mechanism, a rocker arm 10 and a slide bar 7; wherein,
[0046] The gear transmission mechanism includes an externally meshed first gear 4 and a second gear 5;
[0047] Both ends of the rocker arm 10 are fitted with a sliding sleeve 8, and the inner walls of the two sliding sleeves 8 are connected to the two ends of the rocker arm 10 through a first spring 9;
[0048] The sliding rod 7 is provided with an oblique block. By determining the inclination of the oblique blocking block or designing a specific profile to achieve the purpose of variable transmission ratio and smooth door opening process, one end of the sliding rod 7 is flexibly connected by the second spring 6, and the sliding ...

The invention discloses an automatic door opener and a side-by-side combination refrigerator with the same to solve the problem that a door of a high-capacity refrigerator is hard to open. The structural design of sliding rods and inclined check blocks is adopted, and the aim that the transmission ratio is changed in the door opening process, so that the door opening process is smooth is achieved; a rocker arm smoothly crosses over the inclined check blocks to return through a telescopic device or a branched mechanism with pins; and the initial position of the rocker arm is reasonably designed, the idle stroke of a motor is reduced, and the door opening efficiency is improved. The requirements for initial door opening pushing force and door opening time of automatic doors of the refrigerator are met well, and meanwhile compared with an existing door opener, the automatic door opener is simpler and more compact in structure, easy to implement and low in cost, and has good application prospects.
Description
Technical field: [0001] The invention relates to a door opening device for a refrigerator door, in particular to an automatic door opening device and a side-by-side refrigerator using the device. Background technique: [0002] With the improvement of people's living standards, more and more side-by-side refrigerators with large capacity and rich functions have entered the families of ordinary people. However, due to the increase of the volume of the refrigerator and the improvement of the requirements for the insulation effect of the door, the door of the refrigerator becomes more and more heavy. The user feels strenuous when opening the refrigerator door, which even affects the normal use of the elderly and children. [0003] In order to solve such problems, patent applications CN102278033A "An Automatic Door-Opening Device and a Side-by-Side Refrigerator Using the Device" and CN104121748A "Door-Opening Device and a Refrigerator Equipped with the Door-Opening Device" both ...
