Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigerator refrigeration technology, and in particular to a drainage structure for a commercial refrigerator refrigeration unit. Background Technology
[0002] The refrigeration unit of a refrigerator is one of the key components that plays a crucial role in the refrigeration and freezing process. It is usually composed of a compressor, condenser, evaporator, and expansion valve (or throttling valve). Evaporator: The evaporator is the heat exchange device in the refrigeration unit and is located inside the refrigerator. High-pressure liquid refrigerant enters the evaporator through the expansion valve (or throttling valve). After being released inside the evaporator, the temperature and pressure decrease, causing the refrigerant to become a low-temperature, low-pressure vapor. In this process, the evaporator absorbs heat from inside the refrigerator, thereby lowering the temperature of the refrigerator compartment and the freezer compartment.
[0003] During normal use of a refrigerator evaporator, a certain amount of condensate will usually be produced. The main function of the refrigerator evaporator is to convert the refrigerant from a liquid state to a gaseous state and absorb heat from inside the refrigerator. This will cause moisture in the air to condense into water droplets. These water droplets collect inside the refrigerator's refrigeration unit compartment and are usually drained through an external water pipe. Users either use a water storage device to collect the cooling water drained from the refrigerator and pour it out in time, or let the cooling water flow onto the ground. Collecting and frequently pouring out the cooling water only increases the burden on users, while the cooling water flowing onto the ground will seriously affect the appearance and may cause dangers such as electric leakage. Existing refrigerator refrigeration units do not have a good drainage structure. Utility Model Content
[0004] In order to solve the problems mentioned in the background art, the present invention provides a drainage structure for a commercial refrigerator refrigeration unit.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A drainage structure for a commercial refrigerator refrigeration unit includes a water storage tank, a rotary evaporator plate, and a drive control component. The water storage tank includes a fixed bottom trough and adjustment panels disposed on the left and right sides of the fixed bottom trough. Semi-circular side plates are disposed at the front and rear of the fixed bottom trough, and a discharge pipe that enters the interior of the fixed bottom trough is installed at the bottom of the fixed bottom trough.
[0007] The rotary evaporator includes at least one fixed frame symmetrically mounted on the outer peripheral wall of the rotating shaft, and a rotary evaporator connected to the rotating shaft of the fixed frame. The rotary evaporator and the fixed frame are connected by a damping spring member. An evaporation screen is provided on the fixed frame and the rotary evaporator.
[0008] Preferably, the fixed bottom groove is located at the bottom and only covers the bottom part of the semi-circular side plate, thereby forming two windows on the left and right sides of the fixed bottom groove that can be covered and closed by the adjusting enclosure.
[0009] Preferably, the adjusting plate is closely attached to the periphery of the semi-circular side plate, and a liquid level sensor is installed on the upper edge of the adjusting plate. When the adjusting plate is at its lowest position, the upper edge is above the left and right edges of the fixed bottom groove.
[0010] Preferably, the damping spring extends under normal conditions, causing the fixed frame and the rotary evaporator to be in an unfolded state relative to the rotating shaft to which they are connected. The width of the fixed frame is not greater than the radius of the semi-circular side plate. When the fixed frame and the rotary evaporator are in the unfolded state, the distance from the far end of the rotary evaporator to the rotating shaft is greater than the radius of the semi-circular side plate.
[0011] Preferably, the evaporation mesh is composed of densely interwoven resistance heating wires. The evaporation mesh is electrically connected to the transformer installed inside the rotating shaft. A rotation controller is fixedly installed on the outside of the semi-circular side plate. The PLC controller installed inside the rotation controller is electrically connected to the liquid level sensor and the transformer inside the rotating shaft.
[0012] Preferably, a swing control component is installed at the end of the rotating shaft away from the drive controller. The rotating motor inside the swing control component is controlled by the drive controller and connected to the adjusting plate via a connecting arm.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention can effectively collect the condensate produced by the refrigerator evaporator and automatically and efficiently evaporate and discharge it through a rotating evaporation plate. The condensate will not flow into the refrigerator and cause pollution or damage, nor will it flow on the ground and affect the appearance or cause dangers such as electric leakage. Users do not need to pour out the condensate collected in the water tank. The drainage structure of the refrigeration unit is convenient and safe. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Example 1
[0021] Reference Figure 1 and Figure 2 A drainage structure for a commercial refrigerator refrigeration unit includes a water storage tank 1, a rotary evaporator plate 2, and a drive control component 3. The rotary evaporator plate 2 is installed in the water storage tank 1 and is controlled and driven to rotate by the drive control component 3.
[0022] The water storage tank 1 includes a fixed bottom tank 11 and adjustable side plates 12 disposed on the left and right sides of the fixed bottom tank 11. The fixed bottom tank 11 is provided with semi-circular side plates 13 at the front and back. The fixed bottom tank 11 is located at the bottom and only covers the bottom part of the semi-circular side plates 13, thereby forming two windows on the left and right sides of the fixed bottom tank 11 that can be covered and closed by the adjustable side plates 12. The adjustable side plates 12 are close to the periphery of the semi-circular side plates 13 and can be moved along the periphery of the semi-circular side plates 13. When the adjustable side plates 12 move to the bottom of the fixed bottom tank 11, the windows on both sides of the fixed bottom tank 11 open, and the condensate generated by the refrigeration unit is received and collected by the fixed bottom tank 11 until the liquid level rises to the left and right edges of the fixed bottom tank 11.
[0023] A liquid level sensor 14 is installed on the upper edge of the adjusting plate 12. When the adjusting plate 12 is at its lowest position, the upper edge is above the left and right edges of the fixed bottom tank 11, so that the liquid level sensor 14 is positioned above the left and right edges of the fixed bottom tank 11. When the liquid level in the fixed bottom tank 11 overflows the left and right edges of the fixed bottom tank 11, the liquid level sensor 14 will detect the condensate level and transmit the signal to the drive control component 3. The drive control component 3 drives the adjusting plate 12 to move upward until the liquid level sensor 14 just stops detecting the condensate level. When the liquid level sensor 14 stops detecting the condensate level for a predetermined time, the drive control component 3 will control the adjusting plate 12 to move downward until the liquid level sensor 14 can just detect the condensate level. In this way, through the cooperation of the liquid level sensor 14 and the drive control component 3, the adjusting plate 12 can be dynamically adjusted so that the condensate in the water storage tank 1 can just prevent overflow.
[0024] The bottom of the fixed bottom tank 11 is equipped with a discharge pipe 15 that leads into the interior of the fixed bottom tank 11. When the adjustment panel 12 is moved to the last position, the liquid level sensor 14 can still continuously sense the condensate level. The drive control component 3 can open the discharge pipe 15 to urgently discharge the condensate in the water storage tank 1, so as to avoid the condensate overflow and damage the refrigerator refrigeration unit.
[0025] Example 2
[0026] Reference Figure 1 and Figure 2 The difference between this embodiment and Embodiment 1 is that the rotary evaporator 2 includes at least one fixed frame 21 symmetrically mounted on the outer peripheral wall of the rotating shaft 31, and a rotary evaporator 22 connected to the rotating shaft of the fixed frame 21. The rotary evaporator 22 is connected to the fixed frame 21 through a damping spring member 23. Under normal conditions, the damping spring member 23 extends so that the fixed frame 21 and the rotary evaporator 22 are in an unfolded state relative to the rotating shaft to which they are connected. When the fixed frame 21 and the rotary evaporator 22 are in the unfolded state, the distance from the far end of the rotary evaporator 22 to the rotating shaft 31 is greater than the radius of the semi-circular side plate 13, so as to provide a larger evaporation area for the condensate distributed on the evaporation net 24 provided on the fixed frame 21 and the rotary evaporator 22.
[0027] The evaporation mesh 24 is composed of densely interwoven resistance heating wires. The evaporation mesh 24 is electrically connected to the transformer installed inside the rotating shaft 31. A rotation controller 32 is fixedly installed on the outside of the semi-circular side plate 13. The PLC controller installed inside the rotation controller 32 is electrically connected to the liquid level sensor 14 and the transformer inside the rotating shaft 31 to receive the detection signal from the liquid level sensor 14 and control the heating power of the evaporation mesh 24 according to the signal. A swing control component 33 is installed at the end of the rotating shaft 31 away from the rotation controller 32. The rotating motor inside the swing control component 33 is controlled by the rotation controller 32 and connected to the adjusting plate 12 through the connecting arm 34. The rotation controller 32 controls the rotation angle of the rotating motor inside the swing control component 33 according to the detection signal from the liquid level sensor 14, thereby controlling the setting angle of the adjusting plate 12.
[0028] The width of the fixing frame 21 is not greater than the radius of the semi-circular side plate 13, so that when the rotating shaft 31 is driven to rotate axially by the rotation controller 32, the fixing frame 21 can move into the water storage tank 1. When the fixing frame 21 moves in, the rotating evaporator 22, which was originally extended outside the water storage tank 1, will be blocked by the edge of the adjusting plate 12 and will fold in the opposite direction of the rotation of the fixing frame 21, overcoming the rebound force of the damping spring member 23. This allows the evaporation net 24 set on the fixing frame 21 and the rotating evaporator 22 to fully contact the condensate stored in the water storage tank 1 and to pick up more condensate for evaporation. Preferably, the width of the fixing frame 21 is exactly equal to the radius of the semi-circular side plate 13, and the rotating evaporator 22 has an arc that fits against the inner wall of the water storage tank 1, so that after the fixing frame 21 moves into the water storage tank 1, the rotating evaporator 22 can just fit against the inner wall of the water storage tank 1 and move, so that the evaporation net 24 installed on the rotating evaporator 22 can contact the maximum amount of condensate.
[0029] After the fixed frame 21 is removed from the water storage tank 1, it is slowly rebounded by the damping spring member 23 to unfold the rotating evaporator 22. The entire refrigeration unit drainage structure is set near the heat dissipation window 400 at the bottom of the refrigerator. During the rotation of the rotating evaporator 22 as it unfolds, the liquid film formed by the tension on the evaporation net 24 due to the condensate can be quickly evaporated and dissipated into the air. At the same time, the evaporation net 24, which can be heated, can further accelerate the evaporation of the condensate liquid film after heating. Preferably, an exhaust fan blowing towards the heat dissipation window 400 can also be set on the side of the refrigeration unit drainage structure away from the heat dissipation window 400, so that the air above the water storage tank 1 continues to flow, thereby accelerating the evaporation of the condensate liquid film and preventing the air above the water storage tank 1 with increased humidity due to condensate evaporation from flowing to the evaporator of the refrigeration unit and reforming condensate.
