Description

Technical Field

[0002] In the existing rotary Stirling refrigerator structure design, a base structure is usually used as a support body, and the rotor assembly rotates inside the base to drive the movement of each moving pair, ultimately realizing the refrigeration function of the refrigerator.

[0003] When the rotor assembly inside the base drives the various moving parts to work, its internal cleanliness has a great impact on the performance of the refrigerator. However, during the assembly and running-in process of the refrigerator, micron-level excess materials will be generated, which can easily enter the middle of the friction pair or accumulate inside the bearing, causing movement stagnation, and ultimately leading to mechanical failures such as jamming and freezing of the rotary Stirling refrigerator. Furthermore, during the operation of the rotary Stirling refrigerator, parts will generate water vapor. If it is not released in time, the water vapor will cause the internal parts of the refrigerator to rust or even fail prematurely. Utility Model Content

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] Example 1

[0032] like Figure 1 , 2a-2b, this embodiment provides a base of a rotary refrigerator, which includes:

[0033] A base body 1 having an internal cavity 11 for accommodating a part / all of the rotating components of the rotary refrigerator, such as a rotor component, etc.;

[0034] A filter element 3, which is attached to the inner wall surface 13 of the base body 1;

[0035] and a pressing member 2, which has a plurality of through holes 21, covers the outside of the filter element 3, and is connected to the inner wall surface 13 of the base body 1, so as to restrict the filter element 3 on the inner wall surface 13 of the base body 1, and forms a receiving cavity 22 between the filter element 3 and the pressing member 2;

[0036] When the rotating component in the base body 1 rotates, the generated excess matter (such as metal / non-metal particles, etc.) and / or water vapor enters the accommodating cavity 22 through the through hole 21 on the clamping member 2 under the action of the rotating centrifugal force, so that the excess matter is stored in the accommodating cavity 22, and / or the excess matter is adsorbed by the filter element 3, and / or the water vapor is adsorbed by the filter element 3.

[0037] Specifically, Figure 3 As shown, the filter element 3 includes filter paper, such as PTFE filter paper, etc., and its shape can match the shape of the inner wall surface of the base body 1, for example, it can be arc-shaped / ring-shaped; similarly, as Figure 4As shown, the overall shape of the pressing member 2 matches the shape of the inner wall surface of the base body 1 , and the entire pressing member 2 can also be an arc / annular structure, and the filter element 3 fits the inner wall surface 13 of the base body 1 .

[0038] At the same time, the clamping member 2 is connected to the inner wall surface of the base body 1 by a detachable connection method such as bonding and screws / bolts, and as Figure 4 As shown, the pressing member 2 is provided with a pressing member notch 23 on one side of the inner wall surface of the base body 1, and the filter 3 completely covers the pressing member notch 23, so that the accommodating cavity 22 is formed by the pressing member notch 23 and the filter 3. The surrounding of the pressing member notch 23 is in contact with the filter 3, so as to apply pressure to the filter 3, so as to press the filter 3 against the inner wall surface 13 of the base body 1.

[0039] It can be seen that the base structure in this embodiment is simple in design and does not affect the overall structural design of the rotary refrigerator and the assembly between the internal parts. The centrifugal force generated by the rotation of the internal rotating component drives the excess matter and water vapor to automatically enter the accommodating chamber 22, and the excess matter is stored in the accommodating chamber 22, and the water vapor is adsorbed by the filter element 3 to produce a self-cleaning effect, thereby preventing the excess matter from entering the middle of the friction pair or accumulating inside the bearing to cause movement jamming, and avoiding the problem of rusting of parts caused by water vapor.

[0040] Embodiment 2:

[0041] The only difference between this embodiment and embodiment 1 is that the clamping member 2 is made entirely of a bendable elastic element, such as a stainless steel sheet, an aluminum alloy sheet, a plastic sheet, etc., and the diameter of the through hole 21 is 0.5-2 microns (preferably 1 micron) to allow micron-level excess matter and water vapor to pass through.

[0042] Embodiment 3:

[0043] The difference between this embodiment and embodiment 1 or 2 is that Figure 5 As shown, a base body notch 12 is provided on the inner wall surface 13 of the base body 1, and the filter element 3 is completely accommodated in the base body notch 12;

[0044] The pressing member 2 is connected to the inner wall surface 13 of the base body 1 by a detachable connection method such as bonding and screws / bolts, and completely covers the base body notch 12 to form the accommodating cavity 22 between the pressing member 2 and the filter member 3.

[0045] Embodiment 4;

[0046] The difference between this embodiment and embodiment 1 or 2 is that Figure 5As shown, a base body notch 12 is provided on the inner wall surface 13 of the base body 1, and the pressing member 2 and the filter member 3 are completely accommodated in the base body notch 12, and the inner wall surface 23 of the pressing member 2 is flush with the opening of the base body notch 12, so that the pressing member 2 and the filter member 3 can be simultaneously arranged through the base body notch 12, avoiding the pressing member 2 and the filter member 3 from occupying additional space;

[0047] The pressing member 2 is connected to the side wall surface of the base body slot 12 by a detachable connection method such as bonding and screws / bolts, and completely covers the filter element 3 to form the accommodating cavity 22 between the pressing member 2 and the filter element 3 .

[0048] Embodiment 5:

[0049] This embodiment provides a rotary refrigerator, which includes the base and the rotating assembly described in any one of Embodiments 1-4, and the rotating assembly is partially / entirely accommodated in the internal cavity 11.

[0050] To sum up, the utility model has a simple structural design. It drives the excess matter and water vapor generated during the assembly and running-in processes of the refrigerator into the accommodating chamber automatically through the centrifugal force generated by the rotation of the internal rotating component. The excess matter is stored in the accommodating chamber, and the water vapor is adsorbed by the filter element to produce a self-cleaning effect, thereby preventing the excess matter from entering the middle of the friction pair or accumulating inside the bearing to cause movement jamming, and avoiding the problem of rusting of parts caused by water vapor.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
