Abstract
Description
Technical Field
[0001] The utility model relates to a display cabinet defrosting water technology, in particular to a refrigerator defrosting water evaporation structure. Background Art
[0002] The refrigeration system of freezing and refrigerating equipment will produce defrost water when working, and for open freezers, more defrost water will be discharged. The existing treatment technology has shortcomings in equipment safety, convenience and energy consumption.
[0003] In the prior art, one or two layers of water receiving trays are generally provided, and the trays are built with high-temperature exhaust pipes, which are used as evaporation trays to evaporate water. Some are equipped with a pouring tray on this basis. In this solution, the cold defrost water discharged from the cabinet falls directly into the evaporation tray, which quickly lowers the temperature of the high-temperature pipe, so that the defrost water cannot be completely evaporated. The water that is not completely evaporated will fall into the pouring tray. Users need to pour water about twice a day, and even more in high-humidity seasons. When manual water cannot be poured in time, overflow accidents and water accumulation problems are prone to occur, which brings many hidden dangers and inconveniences to users. Utility Model Content
[0004] The utility model aims to provide a defrosting water evaporation structure for a refrigerator to solve the problems in the prior art that the defrosting water in the existing open refrigerator is large, the evaporation is incomplete, and the water overflows due to lack of time to dump the water.
[0005] The technical solution adopted by the utility model to solve the above technical problems is:
[0006] A defrost water evaporation structure for a refrigerator comprises a condenser, a fan, and a defrost water temperature rising plate and an evaporation plate stacked up and down, wherein a high-temperature pipe is arranged inside the evaporation plate, and the fan transports the hot air generated by the condenser when it is working to between the defrost water temperature rising plate and the evaporation plate, and above the defrost water temperature rising plate.
[0007] Preferably, the defrost water temperature rise plate is provided with at least one water hole. When the water hole is located on the inner bottom surface of the defrost water temperature rise plate, a water hole wall extends upward from the edge of the water hole. The height of the water hole wall is lower than the height of the plate wall around the defrost water temperature rise plate.
[0008] When the water hole is located on the inner side of the defrost water temperature rising plate, the water hole is higher than the inner bottom surface of the defrost water temperature rising plate, or the edge of the water hole has a water hole wall extending upward, and the height of the water hole wall is lower than the height of the plate wall around the defrost water temperature rising plate.
[0009] Preferably, at least one first vent is provided on the inner bottom surface of the defrost water temperature rising plate, a first vent wall is extended upward from the edge of the first vent, and the height of the first vent wall is higher than the height of the downhole wall.
[0010] Preferably, at least one second vent is provided on the inner bottom surface of the evaporation tray, the second vent is arranged opposite to the first vent, and a second vent wall extends upward from the edge of the second vent.
[0011] Preferably, the evaporation tray is provided with a plurality of them, and the evaporation tray located at the upper layer is provided with at least one first drain port, and when the first drain port is located on the inner bottom surface of the evaporation tray, a first drain port wall extends upward from the edge of the first drain port, and the height of the first drain port wall is lower than the height of the tray wall around the evaporation tray, and lower than the height of the second vent wall;
[0012] When the first drain port is located on the inner side of the defrost water temperature rising plate, the first drain port is higher than the inner bottom surface of the evaporation plate, or the edge of the first drain port has a first drain port wall extending upward, and the height of the first drain port wall is lower than the height of the plate wall around the evaporation plate.
[0013] Preferably, a drain pipe is further included, and the evaporation disk located at the bottom layer is provided with a second drain port, and the second drain port is connected to the drain pipe.
[0014] Preferably, a compressor is also included, and the high-temperature pipe is a high-temperature exhaust pipe connected to the compressor.
[0015] Preferably, the second ventilation opening in the evaporation tray is staggered with the high-temperature tube, and / or the first drainage opening is staggered with the high-temperature tube.
[0016] Preferably, a plurality of buckles for fixing the high-temperature tubes are provided in the evaporation tray.
[0017] Preferably, it further comprises a fixing bracket for fixing the defrost water temperature rising plate and the evaporation plate, wherein two fixing brackets are provided and are respectively located on opposite sides of the stacked defrost water temperature rising plate and the evaporation plate.
[0018] Compared with the prior art, the advantages of the utility model are:
[0019] 1. The defrost water at 0-5 degrees Celsius discharged from the freezer first falls into the topmost defrost water temperature rise plate, and is heated to the same temperature as the condenser by the hot air from the fan. At this stage, the defrost water has a large temperature rise, and part of the defrost water is evaporated under the action of the hot air.
[0020] 2. When the water surface of the defrost water temperature rising plate is higher than the wall of the drain hole, it overflows from the drain hole to the uppermost evaporator, and the high-temperature exhaust pipe connected to the compressor exhaust port begins to evaporate the heated defrost water. The hot air blown by the fan takes away the water vapor through the defrost water temperature rising plate, the evaporator and the space between two adjacent evaporators. At the same time, the hot air passes through the first and second vents of the defrost water temperature rising plate and the evaporator, and spreads to every corner of the defrost water temperature rising plate and the evaporator to form a turbulent zone, taking away more water vapor and accelerating the evaporation of water, so that the defrost water of the open freezer can be basically completely evaporated at the uppermost evaporator.
[0021] 3. When the unevaporated water in the uppermost evaporator is higher than the top of the first drain outlet wall, it overflows to the second evaporator. Similarly, the high-temperature exhaust pipe begins to evaporate the heated water, and the hot air from the fan takes away the water vapor through the gap between adjacent evaporators. The defrosted water in the open freezer is completely evaporated in the second evaporator.
[0022] 4. Through the high-temperature exhaust pipe of the compressor, when evaporating and condensing water, the exhaust temperature of the compressor is reduced, and the operating energy consumption of the compressor is saved while evaporating water.
[0023] 5. A spare drain pipe is installed at the bottom of the evaporation plate to meet the customer's manual draining needs and possible overflow in extremely high humidity environments (90% and above). BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The defrost water temperature rise plate 3 is located above the stacked evaporation plates 4. In the present application, the evaporation plates 4 are provided with two layers of evaporation plates 4. The defrost water temperature rise plate 3 does not have a high temperature tube 41. The evaporation plate 4 located below is provided with a plurality of buckles 46, and the evaporation tube is fixed by the buckles 46. The defrost water temperature rise plate 3 and the evaporation plate 4 are fixed in the refrigerator by fixed brackets 47 on opposite sides. The number of layers of the evaporation plate 4 can be set according to the space in the refrigerator. It can be a three-layer evaporation plate 4, or a four-layer evaporation plate 4, or even more layers of evaporation plates 4. The fan 2 transports the hot air generated by the condenser 1 when it is working to between the defrost water temperature rise plate 3 and the evaporation plate 4, and above the defrost water temperature rise plate 3.

[0044] When the first drain port 44 is located on the inner side of the defrost water temperature rising plate 3, the first drain port 44 is higher than the inner bottom surface of the evaporation plate 4, or the edge of the first drain port 44 has a first drain port wall 45 extending upward, and the height of the first drain port wall 45 is lower than the height of the plate wall around the evaporation plate 4.
[0045] The evaporation tray 4 at the bottom layer is provided with a second drain port, which is communicated with the drain pipe 5 .
