Description

Technical Field

[0001] This utility model relates to the field of integrated cold storage equipment technology, specifically to a defrosting water discharge mechanism for integrated cold storage equipment. Background Technology

[0002] A cold storage unit is a compact refrigeration device that integrates core components such as a compressor, condenser, evaporator, and electronic control system. It is widely used in food preservation, pharmaceutical cold storage, logistics warehousing, and other fields. The cold storage unit adopts a fully enclosed / semi-enclosed compressor and an integrated design, saving installation space.

[0003] The casing of a cold storage unit houses a compressor, condenser, evaporator, and other components. Frost forms on the inside of the casing and on the surfaces of these components due to temperature differences. When the frost melts, it produces a large amount of water. If this water falls into the casing and cannot be drained promptly, it can cause rust on the casing and its internal components. Some cold storage units have drain holes, but these holes are positioned too high, leading to water accumulation at the bottom of the casing. Therefore, a defrosting water drainage mechanism for cold storage units is proposed. A water pump works to extract the defrosting water from the casing through a first outlet pipe and a filter screen. The filter screen at the bottom of the flexible hose falls to the bottom of the casing due to its own weight, facilitating the complete extraction of defrosting water from the bottom of the casing by the water pump, preventing any residual water inside the cold storage unit. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a defrosting water drainage mechanism for an integrated cold storage unit. The water pump works to extract defrosting water from the casing of the integrated cold storage unit through the first water outlet pipe and the filter screen. The filter screen at the bottom of the telescopic hose falls to the bottom of the casing of the integrated cold storage unit due to its own weight, which facilitates the water pump to completely extract the defrosting water from the bottom of the casing of the integrated cold storage unit, so that no water remains in the casing of the integrated cold storage unit.

[0005] The technical solution adopted by this utility model to solve its technical problem is a defrosting water discharge mechanism for an integrated cold storage unit, including a protective box, a first water outlet pipe and a connecting pipe. A water pump is installed inside the protective box through a mounting bracket. A box cover is fixed to one side of the protective box by bolts, and a timer controller is installed on one side of the box cover through a mounting base. The protective box is provided with a first water outlet pipe on one side. The bottom end of the first water outlet pipe is connected to a telescopic hose through a threaded groove. The bottom end of the telescopic hose is connected to a filter screen through a threaded groove.

[0006] By adopting the above technical solution, the water pump works to extract the defrosting water from the casing of the integrated cold storage unit, and the telescopic hose allows the filter screen to fall to the bottom of the integrated cold storage unit casing due to its own weight.

[0007] Specifically, the water pump is located at the water inlet end of the protective box and is connected to a rotary joint through a threaded groove. One end of the rotary joint is connected to a connecting pipe through a threaded groove.

[0008] Specifically, a limiting ring is fixedly sleeved on the outside of the first water outlet pipe, and a sealing gasket is provided on the side of the limiting ring located on the outside of the first water outlet pipe.

[0009] Specifically, a threaded groove is provided on the outer side of the first water outlet pipe, and a threaded sleeve is welded to one end of the connecting pipe near the first water outlet pipe.

[0010] Specifically, the water outlet of the water pump is connected to a second water outlet pipe via a threaded groove, and the second water outlet pipe passes through the protective box.

[0011] Specifically, the current output terminal of the timing controller is electrically connected to the current input terminal of the water pump via a power supply line.

[0012] The beneficial effects of this utility model are: The defrosting water drainage mechanism of the integrated cold storage unit described in this utility model features a telescopic hose that allows the filter screen to fall to the bottom of the integrated cold storage unit housing due to its own weight. This facilitates the water pump to completely extract the defrosting water from the bottom of the integrated cold storage unit housing, preventing residual water from accumulating at the bottom of the housing.

[0013] The present invention describes a defrosting water discharge mechanism for an integrated cold storage unit. The water pump works by drawing defrosting water from inside the cold storage unit through a rotary joint, connecting pipe, first outlet pipe, telescopic hose, and filter screen, and then discharges it through a second outlet pipe to achieve the purpose of discharge.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] The water pump works to extract defrost water from inside the cold storage unit's casing through the first outlet pipe and the filter screen. The filter screen at the bottom of the flexible hose falls to the bottom of the cold storage unit's casing due to its own weight, facilitating the complete extraction of defrost water from the bottom of the casing by the water pump, ensuring no water remains inside the cold storage unit. Figure 1-3 As shown, the defrosting water discharge mechanism of the integrated cold storage unit of this utility model includes a protective box 1, a first water outlet pipe 3 and a connecting pipe 7. A water pump 2 is installed inside the protective box 1 through a mounting bracket. A box cover 9 is fixed to one side of the protective box 1 by bolts. A timer controller 10 is installed on one side of the box cover 9 through a mounting base. The protective box 1 is provided with a first water outlet pipe 3 on one side. The bottom end of the first water outlet pipe 3 is connected to a telescopic hose 4 through a threaded groove. The bottom end of the telescopic hose 4 is connected to a filter screen 5 through a threaded groove.

[0018] When in use, the water pump 2 works to extract the defrosting water from the cold storage unit housing, and the extension hose 4 allows the filter screen 5 to fall to the bottom of the cold storage unit housing due to its own weight.

[0019] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a rotary joint 6 connected to the water inlet end of the water pump 2 located at the top of the protective box 1 via a threaded groove, and a connecting pipe 7 connected to one end of the rotary joint 6 via a threaded groove.

[0020] In use, one end of the rotary joint 6 is connected to the connecting pipe 7 through a threaded groove and is equipped with a sealing structure. The rotary joint 6 allows the connecting pipe 7 to rotate.

[0021] For example, such as Figure 3 As shown, the present invention also includes a limiting ring 12 fixedly sleeved on the outside of the first water outlet pipe 3, and a sealing gasket 13 is provided on one side of the limiting ring 12 located outside the first water outlet pipe 3.

[0022] During use, the limiting ring 12 is used to limit the first water outlet pipe 3 that penetrates the housing of the integrated cold storage unit, and the sealing gasket 13 seals and prevents slippage between the limiting ring 12 and the housing of the integrated cold storage unit.

[0023] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes a threaded groove 14 on the outer side of the first water outlet pipe 3, and a threaded sleeve 8 welded to one end of the connecting pipe 7 near the first water outlet pipe 3.

[0024] In use, the connecting pipe 7 can be connected to one end of the first water outlet pipe 3 through the threaded sleeve 8 and the threaded groove 14.

[0025] For example, such as Figure 2 As shown, the present invention also includes a second water outlet pipe 11 connected to the water outlet end of the water pump 2 via a threaded groove, and the second water outlet pipe 11 penetrates the protective box 1.

[0026] When in use, the defrosting water pumped by the water pump 2 is discharged through the water outlet pipe 11.

[0027] For example, such as Figure 1 As shown, the present invention also includes a current output terminal of the timer controller 10 that is electrically connected to the current input terminal of the water pump 2 via a power supply line.

[0028] When in use, the timer controller 10 is used to control the timed operation and duration of the water pump 2.

[0029] When using this utility model, the operator extends one end of the first water outlet pipe 3 from inside the cold storage unit housing, so that the limiting ring 12 on the outside of the first water outlet pipe 3 is tightly attached to the inside of the cold storage unit housing. The connecting pipe 7 is connected to one end of the first water outlet pipe 3 through the threaded sleeve 8 and the threaded groove 14. The sealing gasket 13 seals and prevents slipping between the limiting ring 12 and the cold storage unit housing. The power cord is used to connect this device to an external power source. The water pump 2 works by drawing out the defrosting water inside the cold storage unit through the rotary joint 6, connecting pipe 7, first outlet pipe 3, telescopic hose 4 and filter screen 5, and then discharging it through the second outlet pipe 11 to achieve the purpose of drainage. The flexible hose 4 allows the filter screen 5 to fall to the bottom of the cold storage unit housing due to its own weight, making it easy for the water pump 2 to completely extract the defrosting water from the bottom of the cold storage unit housing and avoid water accumulation at the bottom of the cold storage unit housing. The timer controller 10 is set to control the timer control of the water pump 2 and its working duration, so as to facilitate the timed suction and discharge of defrosting water inside the cold storage unit casing. The water pump 2 inside the protective box 1 can be inspected by opening the cover 9.
