Below in conjunction with accompanying drawing and preferred embodiment the utility model is elaborated, wherein:
Fig. 1 is the schematic diagram of existing electrical heating defrosting device;
Fig. 2 is a fundamental diagram of the present utility model;
Fig. 3 is a structural representation of the present utility model;

The specific embodiment
As shown in Figure 1, the conventional electric heating defrosting device is the side installing electrothermal tube 9 at evaporimeter 4, when needs defrost, the supply of solenoid valve shuts feed pipe inner refrigerant, evaporimeter 4 quits work, electrothermal tube 9 is energized and heats simultaneously, utilizes cabinet inner blower 10 to make heated air circulation, reaches the purpose of gradually frost on the evaporimeter 4 being melted.
The utility model comprises: refrigeration system and control device that Condensing units, evaporimeter and expansion gear are formed.The utility model adopts the pattern of water defrosting to solve the defrosting problem, and its operation principle as shown in Figure 2.See also Fig. 2 and Fig. 3, one trickle case 1 is arranged on the upper surface of evaporimeter 4, the sealing of the periphery of this trickle case 1 and upper surface, lower surface many small through hole of evenly arranging, water inlet pipe 2 is introduced defrost water in the trickle case, and the small through hole by the trickle box plate is ejected on the evaporimeter again.The small through hole diameter range that the trickle box plate is evenly arranged is at 0.5 millimeter to 1.5 millimeters, and optimum diameter is 1 millimeter.Water is ejected on the evaporimeter equably in the trickle case in order to make, and a water pipe 3 can be set in the inner transverse of trickle case, and a side of this water pipe is communicated with water inlet pipe 2, and sidewall is evenly distributed with a plurality of small through hole.When needs defrost, cold-producing medium in the feed pipe is cut off, evaporimeter 4 quits work, blower fan 1 is closed simultaneously, afterwards, defrosting water enters water pipe 3 in the trickle case by water inlet pipe 2, flow to trickle case bottom by the through hole on water pipe 3 sidewalls again, spray on the evaporimeter 4 for the treatment of defrost through equally distributed small through hole on the trickle box plate afterwards, defrosting water is back in the cyclic water tank 6 by condensed water discharge outlet 8, trap 12 and return pipe 5, so after circulation a period of time, finish the defrosting task.
Fig. 4 is the embodiment that the utility model is used for the horizontal refrigerator showcase.This device forms a closed-circuit system by the trickle case 1 that is arranged on evaporimeter 4 tops, water pipe 3, water inlet pipe 2, return pipe 5, cyclic water tank 6, water pump 7 and control device, realizes recycling of water resource.Owing to made full use of the original condensed water round of showcase and other space, make of the present utility model rational in infrastructure, small investment, commodity are difficult for softening in the reliability height, cabinet.The more important thing is energy consumption is significantly reduced, the defrosting energy consumption only be the electric heater defrosting pattern 1/80 in addition lower.
In horizontal refrigerator cabinet embodiment of the present utility model, the thickness of described trickle case is slightly less than the heat insulation air layer of original device, and floor space is consistent with the top area of evaporimeter, for preventing upwards conduction of cold air, is coated with heat-insulation layer 13 on the last end face of trickle case.In like manner, discharge outlet 8 lower ends of refrigerator display case also can be provided with trap 12.
During practical operation, when the water inlet of trickle case and water outlet about equally the time, the water that comes out from the through hole that the leaks shape that is in line.Because the trickle box plate is perpendicular to the fin of evaporimeter, for preventing that trickle from causing waste to influence the defrosting effect from middle the passing of fin, the part of evaporator fin near the trickle box plate can be bent,, also can stop cold air up simultaneously to guarantee that trickle can fully flow through each fin.When the water inlet of trickle case greater than the water outlet and suitable hour of the small through hole aperture that leaks, form pressure in the case, the water that comes out from the small through hole that leaks becomes dispersion shape, this moment can be with the fin bending, each fin still can be even water, can play the purpose of water-soluble frost equally.
Because the temperature of defrosting water lowers gradually, influence the defrosting effect, can take following two kinds of methods to improve the temperature of defrosting water: 1, in the water-cooled unit, can connect one section helix tube in Condensing units cooling water outlet pipe road, this helix tube is arranged in the cyclic water tank 6, to improve the temperature of defrosting water; 2, in air-cooled unit, can between condenser and compressor exhaust pipe, connect one section helix tube, this helix tube is arranged in the cyclic water tank 6, to improve the defrosting coolant-temperature gage.
Fig. 5 is the embodiment that the utility model is used for vertical refrigerator display case.Basic structure is same as the previously described embodiments among this embodiment, but because the space of evaporimeter top is bigger in the vertical refrigerator, the trickle case can directly replace with shower nozzle or jet pipe 11, and water inlet pipe 2 is directly introduced defrost water shower nozzle or jet pipe 11, evenly be injected on the evaporimeter, defrosting effect is better.
The utility model is simple in structure, can be used for the existing refrigerator display case in supermarket is carried out reducing energy consumption, also can be applicable to produce novel refrigerator display case.
When water resource was enriched, defrost water can not reclaim yet, and was flowed away by the discharge outlet of showcase.This moment, its economic indicator still was better than the electric defrosting pattern greatly, and defrost water can be to come from closed circuit circulatory system shown in Figure 2, also can come from the backwater of water-cooled condenser, also can directly use the running water of city planting ductwork.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
