Embodiment 1

[0043] Such as Figure 1 to Figure 7 As shown, Embodiment 1 provides an automatic door opening system, including: a control module, and a door opening device controlled by the control module.

[0044] As a preferred embodiment of the door-opening device, the door-opening device includes: a door-opening electromagnet 2 located at the door frame, and a permanent door mounted on the door 1 to cooperate with the door-opening electromagnet 2 to repel the door open or attract the door to close the door. Magnet; the door-opening motor assembly (3) controlled by the control module, the angle sensor connected to the control module for detecting the door angle; when opening the door, the control module is suitable for making the door-opening electromagnet (2) obtain permanent The magnets magnetically repel the working current, and the door opening motor assembly (3) is controlled by the angle sensor to open the door (1) at a corresponding angle.

[0045] As a preferred embodiment of tr...

Embodiment 2

[0060] Such as Figure 4 to Figure 7 As shown, the second embodiment provides a door opening motor assembly 3 .

[0061] The door-opening motor assembly 3 includes: a front-stage gear set 320 located at the door-opening motor end, a rear-stage gear set 330 located at the output shaft 331 end, and an electromagnetic clutch for transmission cooperation between the front-stage gear set 320 and the rear-stage gear set 330 Device 340; wherein the electromagnetic clutch device 340 and the door-opening motor 310 supply power at the same time, that is, after power-on, the front and rear stage gear sets mesh with the clutch gear 341 in the electromagnetic clutch device 340, so that the torque of the door-opening motor 310 is transmitted to the output The shaft 331 is tightly connected with the door shaft of the refrigerator through the output shaft 331, thereby realizing automatic door closing.

[0062] After the door is automatically closed, if the door-opening motor assembly is not ...

Embodiment 3

[0071] On the basis of Embodiment 1 and Embodiment 2, Embodiment 3 provides a working method of the automatic door opening system, that is, the door opening device is controlled by a control device to open or close the door.

[0072] The automatic door opening system is suitable for adopting the automatic door opening system described in Embodiment 2 above. For the structure of the automatic door opening system, please refer to the corresponding content of Embodiment 1, which will not be repeated here.

[0073] If resistance is encountered during the door opening process, after the current detection sensor obtains that the operating current of the door opening motor exceeds the current setting value, the control module controls the door opening motor to lose power, that is, the door hovers; The control module starts the door-opening motor 310 to realize automatic door closing; and after the door is automatically closed, the control module controls the door-opening motor 310 to ...

Abstract

The invention belongs to the field of household appliances and particularly relates to a door opening motor assembly, an automatic door opening system, a work method and a refrigerator. The door opening motor assembly comprises a door opening motor, a front stage gear set, an output shaft, a rear stage gear set and an electromagnetic clutch, wherein the front stage gear set is located at the door opening motor end; the output shaft is used for controlling a door to rotate; and the rear stage gear set is located at the output shaft end. The electromagnetic clutch is used for enabling the front stage gear set to be in transmission fit with the rear stage gear set after being electrified, i.e., after the electromagnetic clutch is electrified, the front stage gear set and the rear stage gear set are engaged with a clutch gear in the electromagnetic clutch, so that the torque of the door opening motor is transmitted to the output shaft. The door opening motor assembly pushes the clutch gear to the transmission position of the front stage gear set and the rear stage gear set after being electrified through the electromagnetic clutch, and the door opening motor transmits power to the output shaft so as to achieve the purpose of automatic door opening and closing; if the power is cut off, the electromagnetic clutch enables the clutch gear to be disconnected from the transmission position; and therefore, the purpose of manual door opening and closing is achieved.

Description

technical field [0001] The invention belongs to the field of home appliances, and in particular relates to a door-opening motor assembly, an automatic door-opening system and a working method, and a refrigerator. Background technique [0002] At present, the automatic door refrigerators on the market often only have a door opening device, but when the door is opened, the opening angle cannot be controlled, and the function of automatic door closing or hovering cannot be realized after the door is opened, which causes many inconveniences during use. [0003] Therefore, in view of the above technical problems, it is a technical problem in the art to design an automatic door opening system and working method that can meet the requirements of door opening, hovering at any angle or automatic closing. Contents of the invention [0004] The purpose of the present invention is to provide a door opening motor assembly to solve the technical problem that the door can be automaticall...
