Description

Technical Field

[0001] The present invention belongs to the technical field of biological sample storage, and in particular relates to an upright ultra-low temperature refrigerator with a frost-breaking structure and a frost-breaking method thereof. Background Art

[0002] Frost formation inside an ultra-low temperature freezer is an inevitable physical phenomenon that cannot be completely eliminated. Frost formation is primarily caused by moisture entering when the door is opened. Therefore, strict operating procedures and regular maintenance are necessary to significantly reduce the rate and extent of frost formation, thereby ensuring efficient operation and temperature stability, extending the life of the equipment, and protecting valuable stored samples.

[0003] Ultra-low temperature freezers typically have multiple partitions inside to store samples in layers. For samples of unusual sizes, one of these partitions may need to be removed to increase storage space. However, if a partition becomes frozen inside the freezer during storage and cannot be removed, transferring the sample is impractical. On-site defrosting is difficult and time-consuming, as the frozen areas between the partitions and the freezer are often located within the chute. This can negatively impact the freezer's temperature control and increase the ingress of moisture, further exacerbating internal frost.

[0004] Therefore, it is urgent to design an upright ultra-low temperature refrigerator with a frost-breaking structure to solve the above-mentioned technical problem that if the partition is frozen inside the ultra-low temperature refrigerator during the storage of samples and cannot be pulled out, the on-site defrosting time is long, resulting in aggravated frost.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0043] Research has found that ultra-low temperature freezers typically have multiple partitions inside to store samples in layers. For samples of unusual sizes, one of these partitions needs to be removed to increase storage space. However, if a partition becomes frozen inside the freezer during storage and cannot be removed, transferring the sample is impractical. On-site defrosting is difficult and time-consuming, as the frozen areas between the partitions and the freezer are often located within the chute. This can negatively impact the freezer's temperature control and increase the ingress of moisture, further exacerbating internal frost.

[0044] Therefore, it is urgent to design an upright ultra-low temperature refrigerator with a frost-breaking structure to solve the above-mentioned technical problem that if the partition is frozen inside the ultra-low temperature refrigerator during the storage of samples and cannot be pulled out, the on-site defrosting time is long, resulting in aggravated frost.

[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0048] Based on the above research, Figure 1 , the disclosed embodiment provides an upright ultra-low temperature refrigerator with a frost-breaking structure, comprising: a refrigerator body 1, which has at least one pair of brackets 2 inside, preferably three pairs, a pair of brackets 2 are respectively arranged on the left and right sides inside the refrigerator body 1, and the bracket 2 is hinged to the refrigerator body 1 at one end facing the inside of the refrigerator body 1, and a partition 5 is suitable for placing above the bracket 2. At the same time, the refrigerator is also provided with at least one limiting frame 11 inside, and one limiting frame 11 corresponds to the position of one bracket 2. Specifically, the limiting frame 11 is located above the bracket 2, and when the bracket 2 is in a horizontal state, the distance between the limiting frame 11 and the bracket 2 is consistent with the thickness of the partition 5. Since the bracket 2 can be rotated and opened downward to an inclined state, when the bracket 2 is open, the partition 5 can also be conveniently inserted between the bracket 2 and the limiting frame 11.

[0049] Reference Figure 1 In at least one embodiment, the vertical ultra-low temperature refrigerator with a frost breaking structure also has a separately arranged barrier seat 3 and a positioning assembly 4. The barrier seat 3 is installed at the end of the bracket 2 away from the hinge, and the positioning assembly 4 is elastically arranged in the refrigerator body 1. Specifically, the positioning assembly 4 is installed on the limit frame 11, and the positioning assembly 4 is elastically connected to the limit frame 11 so that the limit frame 11 can move telescopically on the limit frame 11. At the same time, a through hole is opened on the limit frame 11 so that one end of the positioning assembly 4 can pass through the limit frame 11 and be inserted between the bracket 2 and the limit frame 11. On the other hand, the size of the through hole on the limit frame 11 is slightly larger than

[0050] Reference Figure 2In at least one embodiment, one end of the positioning component 4 is detachably fixedly connected to the barrier seat 3. Preferably, the end of the positioning component 4 facing the barrier seat 3 is threadedly connected to the barrier seat 3, so that the bracket 2 can be manually lifted up and relatively fixed through the positioning component 4, and maintained in a horizontal state to support the partition 5 and the sample on the partition 5.

[0051] Through the above-mentioned arrangement, the blocking seat 3 is connected to the positioning assembly 4 to keep the bracket 2 horizontal, and the blocking seat 3 is separated from the positioning assembly 4 to tilt the end of the bracket 2 away from the hinge downward, and the blocking seat 3 prevents the partition 5 from falling; when the bracket 2 is connected to the refrigerator body 1 by frost, the positioning assembly 4 repeatedly extends and retracts in the direction of the bracket 2 to poke the blocking seat 3 and the bracket 2 to break the frost on the bracket 2 and the refrigerator body 1; when the partition 5 is connected to the refrigerator body 1 by frost, the positioning assembly 4 is stretched in the direction away from the bracket 2 to knock the partition 5 by elastic force to break the frost on the partition 5 and the refrigerator body 1.

[0054] Reference Figure 3 In at least one embodiment, the end of the connecting rod 41 facing the barrier seat 3 has external threads, and the top of the barrier seat 3 defines a blind hole with internal threads. After the operator lifts the bracket 2, they insert the bottom of the connecting rod 41 into the blind hole of the barrier seat 3 and rotate the pull rod 43 to thread the connecting rod 41 into the barrier seat 3, thereby securing the bracket 2. In some embodiments, a stop block can be provided in the middle of the connecting rod 41 so that when the bracket 2 is horizontal, the stop block abuts against the stop frame 11 to maintain balance.
