[0040] Embodiment:

[0041] See Figure 1 and Figure 2 , this embodiment provides a refrigerator, including a box body 1, a first storage box 2, a second storage box 3 and a lifting assembly 4.

[0042] The box body 1 is cylindrical, a refrigerating chamber 11 is arranged inside the box body 1, an inlet and outlet 12 is opened at the top of the box body 1, the inlet and outlet 12 communicates with the refrigerating chamber 11, and a box cover 13 is arranged at the inlet and outlet 12. The lifting assembly 4 is located inside the refrigerating chamber 11, the lower end of the lifting assembly 4 is arranged on the bottom wall of the refrigerating chamber 11, the outer wall of the bottom of the first storage box 2 is supported on the upper end of the lifting assembly 4, and the lifting assembly 4 is used to control the movement of the first storage box 2 in the vertical and horizontal directions. The second storage box 3 is installed on the first storage box 2 so that the second storage box 3 can move synchronously with the first storage box 2, wherein the second storage box 3 is located above the first storage box 2.

[0043] According to the lifting distance of the lifting assembly 4, the refrigerator has a storage state, a first material taking state and a second material taking state.

[0044] When the refrigerator is in the storage state, both the first storage box 2 and the second storage box 3 are located inside the refrigerating chamber 11, and the box cover 13 blocks the inlet and outlet 12. At this time, on the one hand, the box cover 13 prevents the cold air in the refrigerating chamber 11 from overflowing, and on the other hand, it has a light-shielding effect.

[0045] After opening the box cover 13, the lifting component 4 lifts a short distance to convert the refrigerator from the storage state to the first material-taking state. Generally, the items stored in the second storage box 3 do not need to be protected from light. When the refrigerator is in the first material-taking state, the second storage box 3 is located at the inlet / outlet 12, and a part of the second storage box 3 is outside the refrigerating chamber 11 to allow the items in the second storage box 3 to be taken and placed. The remaining part of the second storage box 3 and the first storage box 2 are still located in the refrigerating chamber 11. Generally, the items stored in the first storage box 2 need to be protected from light. At this time, the second storage box 3 can block the inlet / outlet 12, which can not only reduce the leakage of cold air from the refrigerating chamber 11, but also reduce the light irradiating into the first storage box 2, thus avoiding unnecessary damage to the items in the first storage box 2.

[0046] If it is necessary to take and place the items in the first storage box 2, the lifting component 4 needs to continue to lift a distance to convert the refrigerator from the first material-taking state to the second material-taking state. When the refrigerator is in the second material-taking state, the second storage box 3 is completely outside the refrigerating chamber 11, and at the same time, at least part of the first storage box 2 is outside the refrigerating chamber 11.

[0047] It can be seen that regardless of whether the refrigerator is in the storage state, the first material-taking state or the second material-taking state, at least part of the first storage box 2 is always located in the refrigerating chamber 11. Based on this, the outer wall of the first storage box 2 can be attached to the side wall of the refrigerating chamber 11 so that the side wall of the refrigerating chamber 11 can guide the movement of the first storage box 2. Of course, when the refrigerator is in the storage state, there also needs to be a ventilation gap between the first storage box 2 and the second storage box 3 and the side wall of the refrigerating chamber 11 to allow cold air to fill the entire refrigerating chamber 11.

[0048] A second access opening 31 is provided at the top of the second storage box 3. Thus, in the scenario of only taking and placing the items in the second storage box 3, it is only necessary to make the top edge of the second storage box 3 slightly higher than the position where the inlet / outlet 12 is located, so as to minimize the lifting distance required for the lifting component 4 when the refrigerator is converted from the storage state to the first material-taking state.

[0049] Similarly, a first access opening 21 is provided at the top of the first storage box 2 to minimize the lifting distance required for the lifting component 4 when the refrigerator is converted from the first material-taking state to the second material-taking state. In addition, the first storage box 2 and the second storage box 3 are spaced apart to prevent the second storage box 3 from blocking the first access opening 21 and to avoid obstacles when taking and placing the items in the first storage box 2.

[0050] As one way to achieve the spaced arrangement of the first storage box 2 and the second storage box 3, the refrigerator further includes a connecting rod 5. The lower end of the connecting rod 5 is provided on the inner bottom wall of the first storage box 2, and the upper end of the connecting rod 5 is provided on the outer bottom wall of the second storage box 3.

[0051] See Figure 3 and Figure 4 In this embodiment, a first baffle 51, a second baffle 52, a third baffle 53 and a fourth baffle 54 are rotatably arranged on the connecting rod 5. The fourth baffle 54 is located above the third baffle 53, the third baffle 53 is located above the second baffle 52, the second baffle 52 is located above the first baffle 51, the lower surface of the fourth baffle 54 and the upper surface of the third baffle 53 are in the same plane, the lower surface of the third baffle 53 and the upper surface of the second baffle 52 are in the same plane, and the lower surface of the second baffle 52 and the upper surface of the first baffle 51 are in the same plane. The first baffle 51, the second baffle 52, the third baffle 53 and the fourth baffle 54 are all located at the first access opening 21 and can play a certain role in blocking the first access opening 21, so as to reduce the leakage of cold air in the first storage box 2 and reduce the light entering the first storage box 2.

[0052] In this embodiment, the first access opening 21 is circular, the first baffle 51, the second baffle 52, the third baffle 53 and the fourth baffle 54 are all fan-shaped, the outer diameters corresponding to the first baffle 51, the second baffle 52, the third baffle 53 and the fourth baffle 54 are all matched with the diameter of the first access opening 21, and the central angles corresponding to the first baffle 51, the second baffle 52, the third baffle 53 and the fourth baffle 54 are all 90°.

[0053] Taking the first baffle 51 and the second baffle 52 as an example, when the first baffle 51 and the second baffle 52 do not overlap at all, the shielding area of the first baffle 51 and the second baffle 52 for the first access opening 21 is the sum of the areas of the first baffle 51 and the second baffle 52. Since there is a height difference between the first baffle 51 and the second baffle 52, during the rotation of the second baffle 52, the first baffle 51 and the second baffle 52 are gradually stacked together, the overlapping area between the first baffle 51 and the second baffle 52 gradually increases, and the shielding area of the first baffle 51 and the second baffle 52 for the first access opening 21 will also gradually decrease, so as to facilitate the taking and placing of items in the first storage box 2.

[0054] Based on this, when the first baffle 51, the second baffle 52, the third baffle 53 and the fourth baffle 54 do not overlap with each other, the light shielding effect on the first access opening 21 is the best. Therefore, before the first access opening 21 moves above the inlet and outlet 12, the first baffle 51, the second baffle 52, the third baffle 53 and the fourth baffle 54 maintain a non-overlapping state with each other. At this time, a ventilation gap 55 is formed between the fourth baffle 54 and the first baffle 51. Since the size of the ventilation gap 55 is small and is also limited by the light angle, it is difficult for light to enter the first storage box 2 through the ventilation gap 55 before the first access opening 21 moves above the inlet and outlet 12.

[0055] See Figure 5 andFigure 6 In this embodiment, the lifting assembly 4 includes a first connecting rod 41, a second connecting rod 42, a third connecting rod 43, a fourth connecting rod 44, and a telescopic rod 45. The lower end of the first connecting rod 41 is hinged to the bottom wall of the refrigerating chamber 11, and the upper end of the first connecting rod 41 is hinged to the lower end of the fourth connecting rod 44. A sliding groove 111 is provided at the bottom wall of the refrigerating chamber 11, and the lower end of the second connecting rod 42 is slidably arranged at the sliding groove 111. The upper end of the second connecting rod 42 is hinged to the lower end of the third connecting rod 43. The midpoints of the first connecting rod 41 and the second connecting rod 42 are hinged, the midpoints of the third connecting rod 43 and the fourth connecting rod 44 are hinged, and the two ends of the telescopic rod 45 are respectively hinged to the first connecting rod 41 and the third connecting rod 43. The first storage box 2 is supported on the upper ends of the third connecting rod 43 and the fourth connecting rod 44, and the telescopic rod 45 can control the lifting of the first storage box 2 by telescoping.

[0056] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0057] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
