In the related art, a refrigerator is generally fixed at a specific position, and a user can take out food only by pulling a refrigerator door open by hand. However, in some cases, it is inconvenient for the user to move to a position where the refrigerator is installed.

In order to meet the needs of the users, a robot refrigerator is designed in the related art. The robot refrigerator can be moved to the appointed position of the user according to the call signal of the user, so that the user can conveniently take out food stored in the robot refrigerator, and then the user returns to the original position to charge.

In order to further improve the intelligent degree of the robot refrigerator and bring more convenience to users, the user experience is improved, and part of the robot refrigerator also sets the refrigerator door to be capable of being controlled to be automatically opened and closed. For example, after the robot refrigerator moves to a user-designated position, the robot refrigerator controls the refrigerator door to be opened so as to facilitate a user to take out food stored in the robot refrigerator, and then the robot refrigerator controls the refrigerator door to be closed so as to facilitate heat preservation of the food stored in the robot refrigerator.

Referring to fig. 1 and 2, it can be understood that the refrigerator of one embodiment of the related art includes a cabinet 101, a driving mechanism, and a top cover 102, wherein an opening 201 is provided on the cabinet 101, the opening 201 is provided on a top surface of the cabinet 101, and the top cover 102 is used to open or close the opening 201, and the driving mechanism is a lifting mechanism 703. Specifically, referring to fig. 1, the driving mechanism drives the top cover 102 to cover the opening 201, so as to close the case 101. Referring to fig. 2, the driving mechanism drives the top cover 102 to lift upwards at this time, so as to open the opening 201, thereby facilitating the user to access the food materials in the refrigerator.

Referring to fig. 3, 4 and 7, it can be appreciated that the refrigerator according to the embodiment of the present utility model further includes a sensing piece 301 and a controller 701 (e.g., a chip), the sensing piece 301 being mounted on the case 101 and disposed at the opening 201. The controller 701 is configured to receive the signal transmitted by the sensing piece 301 and send a control signal to the driving mechanism to control the driving mechanism to operate. During the lifting movement of the top cover 102, when the user's hand extends into the refrigerator interior area, the sensing piece 301 and the controller 701 play a role in preventing the user from clamping, that is, the sensing piece 301 senses that the user's hand extends into the opening 201, and the controller 701 controls the driving mechanism to act, so that the lifting movement and the door opening movement of the top cover 102 are stopped, and the user's hand is prevented from being clamped, so that the safety of the user is protected.

Referring to fig. 5 and 6, it can be understood that the sensing piece 301 is a circular metal thin plate, which is relatively thin in the thickness direction, for example, 0.3mm to 0.5mm, and the sensing piece 301 is used to sense a capacitance change. Specifically, the instantaneous moving direction of the top cover 102 is a first direction when the door is opened, and the sensing piece 301 is used to sense the capacitance change generated in a second direction and form a capacitance signal, where the second direction is perpendicular to the first direction. I.e. the first direction is the axial direction of the sensor strip 301 (i.e. the up-down direction in fig. 6) and the second direction is the radial direction of the sensor strip 301 (i.e. the left-right direction in fig. 6), so that only in the area of the sensor strip 301, which is perpendicular to the plane of the sensor strip 301, a significant change in capacitance signal can be produced, whereas in the axial direction parallel to the sensor strip 301, a significant change in capacitance signal is hardly produced. Therefore, when the top cover 102 and the food material are lifted along the axial direction of the sensing piece 301, error signals are not easy to generate, and when hands approach the sensing piece 301, variable capacitance signals are generated, the variable capacitance signals are collected by the controller 701, and the controller 701 processes the variable capacitance signals and then controls the lifting mechanism 703 through the peripheral driving circuit, so that the movement and the stop of the lifting mechanism 703 and the top cover 102 are realized.

It should be noted that the sensing piece 301 may also have other shapes, such as a rectangular shape, a sheet shape, or a strip shape.

Referring to fig. 7, it can be understood that a storage compartment 702 is provided in the case 101, and the storage compartment 702 is used for storing food materials, so as to realize low-temperature storage of the food materials. The storage compartment 702 may be a refrigeration compartment, a freezer compartment, or a temperature change compartment. The opening 201 communicates with the storage compartment 702, that is, the opening 201 is located above the storage compartment 702, and a user can store food in the storage compartment 702 through the opening 201, or can take out food in the storage compartment 702 through the opening 201.

Referring to fig. 2 and 4, it can be understood that the refrigerator further includes a support bar 706 and a tray 202, wherein the upper end of the support bar 706 is fixedly coupled to the top cover 102, and the tray 202 is coupled to the support bar 706, such that the support bar 706, the tray 202 and the top cover 102 can be coupled as one unit, i.e., the support bar 706, the tray 202 and the top cover 102 can be raised and lowered together in an up-down direction. The lifting mechanism 703 is used for driving the supporting rod 706, the tray 202 and the top cover 102 to lift together, when the lifting mechanism 703 drives the supporting rod 706, the tray 202 and the top cover 102 to lift, the top cover 102 opens the opening 201, and food carried on the tray 202 can extend out of the opening 201 without extending hands of a user into the storage compartment 702, so that the food is convenient for the user to take. When the lifting mechanism 703 drives the support rod 706, the tray 202 and the top cover 102 to descend, the food material carried on the tray 202 is retracted into the storage compartment 702, and the top cover 102 covers the opening 201 to seal the food material in the storage compartment 702. The lifting mechanism 703 may be connected to the tray 202, and drives the support rod 706 and the top cover 102 to lift by driving the tray 202. The lifting mechanism 703 can also be connected with a supporting rod 706, and drives the tray 202 and the top cover 102 to lift by driving the supporting rod 706. The lifting mechanism 703 can also be connected with the top cover 102, and drives the tray 202 and the support rod 706 to lift by driving the top cover 102.

Because the top cover 102 and the tray 202 are fixed on the supporting rod 706, the supporting rod 706 is sleeved on the upright post, and the supporting rod 706 can move up and down along the upright post by driving the pulley block to act through the motor, so that the top cover 102 and the tray 202 are driven to lift together, and door opening and closing actions are realized.

In other embodiments, the lifting mechanism 703 may be a linear sliding table module, or may be an electric push rod, and may be capable of driving the support rod 706 to slide on the upright, which is not limited herein. The pulley block is adopted to connect the upright post and the supporting rod 706, so that the upright post and the supporting rod 706 are not rigidly connected, and even if the connection between the lifting mechanism 703 and the controller 701 fails, the top cover 102 is pressed on the hand of the user, the pulley block continues to loosen the rope, and the lifting mechanism 703 can not drive the top cover 102 to clamp the hand of the user, so that the hand of the user is only stressed by gravity.

A compressor may also be disposed in the storage compartment 704, and by disposing the controller 701, the compressor, the motor, and at least a portion of the transmission mechanism within the storage compartment 704, the space utilization of the storage compartment 702 may be improved.
