[0032] The present application will be further described below with reference to the accompanying drawings.
[0033] The refrigerator with the up-and-down moving door opening structure of the present application comprises a cabinet 1, an upper door body 2 and a lower door body 3 installed with the cabinet 1, and the positions of the cabinet 1 on both sides of the upper door body 2 and the lower door body 3 are defined as cabinet side wings 10.
[0034] Ω-shaped sliding tracks 4 are recessed on the cabinet side wings 10, and a motor 5, a lead screw 6 and a wire sleeve 7 are installed in the Ω-shaped sliding tracks 4. The lead screw 6 is installed below the motor 5 through a coupling, and the wire sleeve 7 is installed on the lead screw 6. The motor 5 can drive the lead screw 6 to rotate in both directions, and the wire sleeve 7 on the lead screw 5 moves up and down with the rotation of the lead screw 6. The opening of the Ω-shaped sliding track 4 is formed as a narrow slit (not shown) in the vertical direction.
[0035] Dial sliding grooves 11 are recessed on the side of the cabinet side wings 10 away from the Ω-shaped sliding tracks 4, and the positions between the Ω-shaped sliding tracks 4 and the dial sliding grooves 11 are door closing sliding tracks 12. A dial 8 is installed in the dial sliding groove 11. The cross section of the dial 8 is roughly triangular, and the two corners of the vertical perpendicular edge of the dial 8 are respectively formed with shafts 80 protruding backward to slide in the dial sliding groove 11. A hook portion 81 is formed by bending at the other corner of the dial 8, and a fixing hole 82 is formed at the middle position of the horizontal perpendicular edge of the dial 8. A tension spring 9 is installed on the fixing hole 82, and the lower end of the tension spring 9 is fixed on the cabinet side wing 10.
[0036] The door shaft groove 120 is recessed on the door closing slide 12 and connected with the narrow slit. The door horizontal shaft (not shown) is installed on both sides of the upper door body 2 and the lower door body 3, and is installed in the door shaft groove 120 and can move along the path of the door shaft groove 120 and the narrow slit.
[0037] The wire sleeve 7 comprises a main body part 70 and a guide part 71 on the main body part 70. A wire hole 72 is formed in the middle of the main body part 70 and penetrates the upper and lower surfaces of the main body part 70, and the wire rod 6 passes through the wire hole 72. Two gap notches are recessed on the outer circumferential surface of the main body part 70 and are spaced apart to form a hook 74. A guide shaft 75 is formed on the outer circumferential surface of the main body part 70. The two gap notches are a 70° gap notch 730 close to the guide shaft 75 and a 0° gap notch 731 away from the guide shaft 75.
[0038] A 70° guide slope 710, a 0° guide slope 711 and a -50° guide slope 712 are sequentially formed on the upper surface of the guide part 71 from the position close to the 0° gap notch 731. The 70° guide slope 710, the 0° guide slope 711 and the -50° guide slope 712 are collectively referred to as a wire sleeve slope.
[0039] A guide groove 40 is recessed on the inner surface of the Ω-shaped slide 4. The guide groove 40 comprises a 0° groove consistent with the vertical direction angle of the Ω-shaped slide 4, a 35° groove with an included angle of 35° to the right of the 0° groove, a 70° groove with an included angle of 70° to the right of the 0° groove, and a -50° groove with an included angle of 50° to the left of the 0° groove.
[0040] The movement logic of the wire sleeve 7 is as follows:
[0041] When the wire rod 7 moves clockwise, the wire sleeve 7 follows the wire rod 6 to move clockwise. Under the action of the guide groove 40, the guide shaft 75 of the wire sleeve 7 will tightly move upward along the right side of the guide groove 40.
[0042] When the wire rod 7 moves counterclockwise, the wire sleeve 7 follows the wire rod 6 to move counterclockwise. Under the action of the guide groove 40, the guide shaft 75 of the wire sleeve 7 will tightly move downward along the left side of the guide groove 40.
[0043] Under the action of the guide groove 40, the upper and lower parts of the wire sleeve 7 will have different angle states.
[0044] In the present application, the wire sleeve 7 in the Ω-shaped slide 4 comprises four states, which are as follows:
[0045] State one: the guide shaft 75 is located in the 0° groove, and the hook part 81 is located in the 0° gap notch 731.
[0046] State two: the wire sleeve 7 rotates 35° clockwise, the guide shaft 75 is located in the 35° slot, and the hook part 81 is located between the two position-allowing notches 73 to form a hook 74.
[0047] State three: the wire sleeve 7 rotates 70° clockwise to the position, the guide shaft 75 is located in the 70° slot, and the hook part 81 is located in the 70° position-allowing notch 730.
[0048] State four: the wire sleeve 7 rotates from 0° to -50° counterclockwise to the position, the guide shaft 75 is located in the -50° slot.
[0049] The wire sleeve 7 in the guide slot 40 also includes four states in the application, which are as follows:
[0050] State one: 0° position, the wire sleeve bevel is directed to the door closing slide 12, and the door horizontal shaft is guided to the door closing slide 12.
[0051] State two: 35° position, the wire sleeve bevel is directed to the door closing slide 12, and the same as the tab 8 is upward.
[0052] State three: 70° position, the wire sleeve bevel is reversed to the door closing slide 12, and the door horizontal shaft cannot enter the door closing slide 12.
[0053] State four: -50° position, the wire sleeve bevel is reversed to the door closing slide 12, and the door horizontal shaft cannot enter the door closing slide 12.
[0054] In the refrigerator provided with the up-down moving door opening structure, the tab 8 is also arranged in the cabinet side wing 10 at both sides of the door body, and under the action of the moving wire sleeve 7, the tab 8 can push away the upper door body 2 and the lower door body 3 attracted to the cabinet, so as to make the upper door body 2 and the lower door body 3 away from the cabinet and enter the Ω-shaped slide 4 from the door closing slide 12. The tab 8 is provided with the tension spring 9, and has a self-resetting function.
[0055] In the up-down movement of the wire sleeve 7, the wire sleeve 7 rotates, the contact surface of the wire sleeve 7 supporting the door horizontal shaft has a corresponding inclined surface having a guiding effect. In the rotating process, the door horizontal shaft tends to different sliding trends on different inclined surfaces. Meanwhile, the wire sleeve 7 is provided with a place where the tab 8 can be hung and a position-allowing notch allowing the tab hook part to be opened. Under the movement condition, the wire sleeve 7 can hang and move the tab 8. When rotating to a certain angle, the tab hook part is located at the notch position of the wire sleeve, the tab hook falls off, and the tab resets.
[0056] When opening the door, the motor 5 rotates the lead screw 6 to drive the wire sleeve 7 to move. The wire sleeve 7 moves to the tab 8, hangs the tab 8, and the tab 8 separates the door cabinet to push the door into the slide where the wire sleeve 7 is located. The door body is moved up and down along the slide by the wire sleeve 7, moves the upper door to the surface of the lower door, or moves the lower door to the surface of the upper door. When closing the door, the wire sleeve 7 pushes the door to the corresponding position of the slide, rotates to the corresponding angle, and makes the door slide to the closing position according to the guide.
[0057] The above description is only the preferred embodiment of the present application, it should be pointed out that for those skilled in the art, without departing from the principles of the present application, can also make several improvements, these improvements should also be considered as the protection scope of the present application.
