Description

Technical Field

[0001] The invention relates to the technical field of refrigeration structures, in particular to a refrigeration device suitable for preserving vegetables. Background Art

[0002] Vegetable refrigeration devices generally include compressors. During the refrigeration process, the compressor and the storage tank work in a cycle through a circulation pipe. A liquid separator is generally provided in the circulation pipe. The purpose of the liquid separator is to make the refrigerant pass through the liquid separator and then be evenly distributed to each process of the evaporator after being throttled by the capillary tube, so as to achieve uniform and equal liquid supply to the evaporator, so that the refrigerant can evaporate and absorb heat with maximum efficiency, thereby optimizing the performance of the evaporator and achieving the best refrigeration effect.

[0003] The position of the separator plate in the existing vegetable refrigeration device is fixed. When the compressor is working, the liquid passes through the separator plate. When the compressor stops running (reaching the set temperature), part of the liquid remains on the separator plate and cannot be eliminated. Over a long period of time, thick scale will form, causing the separator plate to be blocked.

[0004] To this end, we propose a refrigeration device suitable for preserving vegetables. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 8 The present invention provides a technical solution: a refrigeration device suitable for preserving vegetables, comprising a compressor 1 and a storage tank 2, a one-way circulation pipe 3 is provided between the compressor 1 and the storage tank 2, the compressor 1 is connected to a separator 4 through a pipeline, a condenser 5 is provided between the separator 4 and the storage tank 2, an evaporator 6 is provided on the storage tank 2, and the evaporator 6 cooperates with the compressor 1 through the one-way circulation pipe 3;

[0032] It also includes an incomplete bevel gear 7 and a shaking piece and a liquid separator plate 8 located in the one-way circulation pipe 3, with movable grooves 9 at both ends of the liquid separator plate 8, and a telescopic rod 10 is rotatably connected in the movable groove 9 through the shaking piece, and a movable rod 11 passing through the one-way circulation pipe 3 is hinged at one end of the telescopic rod 10, and a bevel gear 12 is meshed on the incomplete bevel gear 7, and a rotating rod 13 is rotatably connected to the bevel gear 12, and a movable part is provided between the rotating rod 13 and the movable rod 11;

[0033] The movable part rotates the rotating rod 13 to make the movable rod 11 rotate and flip the liquid separation plate 8, and the incomplete bevel gear 7 is pressed and matched with the rotating rod 13, so that the movable rod 11 reciprocates back and forth, and cooperates with the shaking part to make the flipped liquid separation plate 8 move;

[0034] In the present application, the compressor 1 is made to perform irreversible circulation processing through the one-way circulation pipe 3, and liquid is transported from the end of the evaporator 6, thereby achieving a continuous and stable refrigeration effect on the vegetables.

[0035] The movable part includes a self-rotating rod 14 connected and fixed to the central axis of the bevel gear 12, the end of the self-rotating rod 14 is rotatably connected to the rotating rod 13 through a torsion spring rod, the other end of the rotating rod 13 is hinged with a sliding rod 15, the end of the movable rod 11 is fixedly connected to a sliding plate 16, the sliding plate 16 is provided with a sliding groove 17, the end of the sliding rod 15 is slidably connected to the sliding groove 17, and a power part is provided on the outer surface of the one-way circulation pipe 3;

[0036] In the present application, when the compressor 1 stops running, the incomplete bevel gear 7 is rotated by the power member, driving the bevel gear 12 to rotate 180°, and the rotation rod 14 is rotated 180°, so that the rotating rod 13, the sliding rod 15 and the sliding plate 16 located above are all rotated to the lower position. During this process, the rotating rod 13 is always in a vertical state without tilting, and the rotating rod 13 located at the lower position is vertically attached to the edge of the incomplete bevel gear 7 (the rotating rod 13 does not contact the teeth of the incomplete bevel gear 7 during this process), thereby driving the liquid separation plate 8 to flip, so that the liquid separation plate 8 with liquid retained on the top surface is flipped downward;

[0037] The incomplete bevel gear 7 continues to rotate and is out of contact with the bevel gear 12. Under the action of the stabilizing member, the bevel gear 12 and the self-rotating rod 14 remain in position;

[0038] Then, the latching teeth of the incomplete bevel gear 7 contact the vertical rotating rod 13, causing the rotating rod 13 to tilt and shake under the action of the torsion spring rod (the spacing between the adjacent latching teeth of the incomplete bevel gear 7 causes the rotating rod 13 in contact therewith to shake), and the tilted rotating rod 13 acts on the sliding plate 16 to make the movable rod 11 move in the horizontal direction, thereby making the movable rod 11 reciprocate, and the reciprocating movable rod 11 drives the telescopic rod 10 to move, thereby making the liquid separation plate 8 flipped downward to shake back and forth, further clearing the liquid retained on the liquid separation plate 8;

[0039] When the sliding plate 16 slides along the sliding groove 17 , it always maintains a horizontal state.

[0040] The power part includes a fixed plate 18 connected and fixed to the outer surface of the one-way circulation pipe 3, a motor 19 is embedded in the fixed plate 18, the output shaft of the motor 19 is connected and fixed to the middle shaft of the incomplete bevel gear 7, the end of the self-rotating rod 14 is connected and rotated in the fixed plate 18, and a stabilizing member matching the fixed plate 18 is provided at the end of the movable rod 11;

[0041] When the compressor 1 stops, some liquid is retained on the liquid separation plate 8. If it is not cleaned for a long time or the compressor 1 is not started, the liquid is likely to accumulate and form scale on the liquid separation plate 8. In this application, when the compressor 1 stops, the motor 19 is started (rotated at a certain angle) to flip the liquid separation plate 8, so that the retained liquid originally located on the top of the liquid separation plate 8 is flipped to face downward, and the flipped liquid separation plate 8 is shaken to increase the cleaning effect;

[0042] Before restarting the compressor 1 , the motor 19 is started in reverse to reset the overturned liquid separator 8 , and the reset state is stably maintained under the action of the stabilizing member, thereby ensuring the filtering effect of the liquid separator 8 .

[0043] The stabilizing member includes a fixed sleeve 20 connected and fixed to the end of the movable rod 11, a plug rod 21 is provided in the movable sleeve inside the fixed sleeve 20, and a card slot 22 for plugging and matching with the plug rod 21 is provided on the fixed plate 18. Before the liquid separator 8 is turned over, the plug rod 21 is plugged into the card slot 22. When the gas and liquid in the compressor 1 enter the separator 4 through the one-way circulation pipe 3, the stability of the liquid separator 8 is ensured to avoid the instability of the liquid separator 8 caused by the passage of gas and liquid;

[0044] After flipping over the separator plate 8 and shaking it until there is no residue on the separator plate 8, the separator plate 8 needs to be reset. Under the action of the movable part, the rotating rod 14 is reset and rotated, so that the vertical plug-in rod 21 is reinserted into the slot 22, thereby completing the stable fixation of the separator plate 8.

[0045] The stabilizing member also includes a telescopic sleeve rod 23 with a compression member inside. The top of the telescopic sleeve rod 23 is connected and fixed to the fixed plate 18, and an arc plate 24 is provided at the bottom of the telescopic sleeve rod 23. The arc plate 24 is frictionally matched with the rotation rod 14. When the liquid separation plate 8 is flipped over, the teeth of the incomplete bevel gear 7 are disengaged from the bevel gear 12. Under the pressure of the arc plate 24, the telescopic sleeve rod 23 presses the fixed rotating rod 13, so that the rotating rod 13 maintains this state, that is, the flipped state of the liquid separation plate 8 is maintained.

[0046] An arc groove 25 is provided on the non-tooth edge of the incomplete bevel gear 7. When the liquid separator plate 8 flips over, the rotation rod 14 drives the rotating rod 13 to flip over. At this time, the edge of the rotating rod 13 contacts the arc groove 25, and the rotating rod 13 is in a vertical state. When the teeth of the incomplete bevel gear 7 disengage from the bevel gear 12, the teeth of the incomplete bevel gear 7 that continues to rotate contact the rotating rod 13, causing the rotating rod 13 to tilt, and cooperate with the elastic rod to shake the tilted rotating plate, thereby shaking the flipped liquid separator plate 8.

[0047] The shaking member includes a connecting rod 26 located in the movable groove 9 and connected and fixed to the liquid separation plate 8. The connecting rod 26 is hinged to the end of the telescopic rod 10. The end of the other telescopic rod 10 is hinged to the inner wall of the one-way circulation pipe 3. A limiter is provided between the liquid separation plate 8 and the one-way circulation pipe 3.

[0048] After the separator plate 8 is flipped over, the movable part causes the movable rod 11 to move back and forth, thereby driving the telescopic rod 10 hinged to the movable rod 11 to move back and forth. The telescopic rod 10 simultaneously tilts and rotates in the vertical plane. Under the action of the limiter, the other telescopic rod 10 tilts and rotates synchronously, so that the flipped separator plate 8 shakes along the one-way circulation pipe 3, so that the accumulated liquid on the separator plate 8 is quickly shaken off to avoid accumulation on the separator plate 8 and the formation of thick scale under long-term action.

[0049] The limiter includes two symmetrically distributed slide posts 27. The inner wall of the one-way circulation pipe 3 is provided with a slide groove 28 that slides with the slide posts 27. The extension lines of the two slide posts 27 and the extension lines of the two connecting rods 26 are intersected at right angles. The limiter facilitates the flipping and shaking of the liquid separation plate 8.

[0050] The liquid separator plate 8 is located at the connection of the one-way circulation pipe 3 , and the liquid separator plate 8 can be easily replaced by opening the connection of the one-way circulation pipe 3 .
