Problems solved by technology

[0004] Most of the self-opening refrigerators that appear on the market use electromagnets. The electromagnetic force generates magnetic force to attract the push rod, and the resulting impact force pushes the refrigerator open. The thrust of the push rod is very large, which is easy to accidentally injure the user.

specific Embodiment 1

[0036] see Figure 1-2 As shown, the present invention is an automatic door opening device for a refrigerator, which includes a device body 1 and a box cover 2, and the device body 1 is installed on the top of the refrigerator; the device body 1 includes a motor 11, a reduction gear set, a gear push rod 17, and a limit switch 18 , device body bottom box 19, reset switch 20; motor 11, reduction gear group, gear push rod 17, limit switch 18, reset switch 20 are all installed on the device body bottom box 19; a worm screw is installed on the output shaft of motor 11 12. The motor 11 is connected to the reduction gear set through the worm 12; the reduction gear set includes a worm gear 13, a first-stage reduction gear 14, a second-stage reduction gear 15 and a third-stage reduction gear 16; wherein, the worm gear 13 meshes with the worm 12; the third-stage reduction gear The gear 16 is connected with the gear push rod 17; the motor 11 drives the gear push rod 17 to slide reciproca...

specific Embodiment 2

[0041] Such as Figure 4 As shown, a method for controlling an automatic door-opening device of a refrigerator comprises the following steps:

[0042] SS01. The user inputs a door-opening signal. After the device body 1 receives the door-opening signal, the motor 11 rotates to drive the reduction gear set to drive the gear push rod 17 out, and the push rod 171 pushes the refrigerator door;

[0043] SS02. When the toggle block 175 on the gear push rod 17 touches the limit switch 18, the motor 11 reverses, and the gear push rod 17 slides backward;

[0044]When the toggle block 175 touches the reset switch 20, the motor 11 stops rotating;

[0045] The motor 11 sets the upper limit of the running time. When the continuous running time reaches the upper limit time, the toggle block 175 does not touch the reset switch or the limit switch, and the motor 11 stops.

[0046] Wherein, the door opening signal is a key switch signal or a voice signal; the user controls the operation of t...

Abstract

The invention discloses a refrigerator automatic door opening device and a control method of the refrigerator automatic door opening device and relates to the field of refrigerator manufacturing. Therefrigerator automatic door opening device comprises a device body and a box cover. An output shaft of a motor is provided with a worm, and the motor is connected with a speed reduction gear set through the worm. The speed reduction gear set is connected with a gear push rod. The gear push rod comprises a push rod and a gear bar. The two opposite surfaces of the gear bar are provided with a pulling block and a rack correspondingly. The two opposite side faces of the rack bar are provided with push rod guide rails correspondingly. The motor drives the gear push rod to slide along a guide slot in a reciprocating manner through the speed reduction gear set. The gear push rod is matched with a collision block installed on a refrigerator door. The motor drives the speed reduction gear set to drive the gear push rod to perform reciprocating movement, the push force of the push rod can be uniform, the speed is controllable, influences of inertia on door opening of a refrigerator are reduced,and use safety of users is guaranteed; and the push rod and the gear bar are connected in a threaded manner, the refrigerator automatic door opening device is easy to use and convenient to detach, andthe situation that door closing of the refrigerator is influenced by gear stuck-teeth caused by power failure is prevented.

Description

technical field [0001] The invention belongs to the technical field of refrigerator manufacturing, and in particular relates to an automatic door-opening device for a refrigerator and a control method thereof. Background technique [0002] At present: With the development of intelligent home appliances, whether it is large appliances such as refrigerators, washing machines, air conditioners, and color TVs, or small appliances such as air purifiers and kitchen and bathroom supplies. Both advocate technology and intelligence. The concept matches the upgrading needs of Chinese consumers, and intelligence is already a trend in the development of home appliances. [0003] In people's lives, we often encounter such troubles. When you hold items in both hands at the same time and want to put the items in the refrigerator, you must first put down the items and then open the refrigerator. Adding an automatic door opening device to the refrigerator can solve your troubles. By voice...
