Description
Technical field
The present invention relates to a kind of defroster of refrigerator, specifically is a kind of frost removal of realizing the frostless operation of evaporator of refrigerator with the salt solution spraying evaporator.Be used for the refrigeration air-conditioner field.
Background technology
In air cooling type refrigerator, evaporimeter is installed in the booth, makes air circulation in the casing flow through evaporimeter by fan and makes the casing cooling.Because the food that stores in the refrigerator discharges steam, will form frosting at evaporator surface when steam flows through the evaporimeter of low temperature.If the untimely removing of the frosting of evaporator surface will be stopped up air duct and be reduced heating surface, air drag can enlarge markedly naturally, obviously influences heat exchange efficiency, causes the overall performance of refrigerating plant to descend.
The Defrost method that refrigerator is commonly used is that the electrically heated mode of employing is regularly melted the frosting on the evaporimeter at present.Under quitting work, this Defrost mode compressor in defrost process carries out, and because the heat effect of electric heater, temperature can rise in the casing, and the fresh-keeping of food is affected.Electric heater needs consumed power in the defrost process, and liberated heat has increased the weight of burden for later refrigerating operaton in the defrost process, and system energy consumption is increased.
By literature search, find China Patent No.: 02129142.X, name is called: defrosting device for refrigerator.This patent readme is: the invention discloses a kind of defrosting device for refrigerator, the cold air path that comprises circulation box house cold air, cold air path is provided with the evaporimeter that constitutes freeze cycle, the aqua storage tank that the storage normal-temperature water is arranged above evaporimeter, be connected with the switching valve that optionally water of aqua storage tank is fed to the evaporimeter upper end between aqua storage tank and evaporimeter upper end, the below of evaporimeter is provided with the dust-collecting bucket of the water that collection melts from evaporimeter.In addition, the circulation line that is connected with between dust-collecting bucket and aqua storage tank is pumped into circulating pump in the aqua storage tank with the water of dust-collecting bucket.Utilize the water of normal temperature to remove attached to the frost on the evaporimeter, the rising of box house temperature has improved cooling effectiveness when having prevented to carry out defrost process.Do not have energy consumption though this patented technology has realized the defroster process, spin manifold temperature gos up less, has reduced the energy consumption of system.But this system still can frosting in when operation, still need regular close compressor defrosting, and normal-temperature water spray defrost speed is slower, and the water that remains in after the defrost on the evaporimeter can freeze when operation at once, causes thermal resistance to increase influence and conducts heat and effectively carry out.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, a kind of frost removal of realizing the frostless operation of evaporator of refrigerator with the salt solution spraying evaporator is proposed, in the refrigerator running, continue spraying evaporator with the low-freezing aqueous solution, utilize solution to have subzero characteristic, the continuous device of defrosting in running, thus the frosting phenomenon of evaporimeter eliminated.Because the most common and nonhazardous effect of salt (sodium chloride), so the present invention adopts sodium chloride solution as defrosting liquid.The solution that is in operation is sprayed onto on the evaporimeter by spray thrower, makes the evaporimeter all the time can frosting, and Pen Lin solution has played the effect that increases heat exchange area, augmentation of heat transfer simultaneously.
The present invention is achieved by the following technical solutions, the present invention includes: spray thrower, collecting tank, circulation pipe, circulating pump, ball float, water compensating valve, catch the network of rivers, overfall, densimeter, liquid level gauge, storage tank, discharging tube, blower fan, air channel, saturated common salt solution.
Spray thrower is the cuboid box, is arranged in directly over the evaporimeter, and keeps the distance of 5mm to 10mm with evaporimeter.The spray thrower area is bigger slightly than evaporimeter, and its one side towards evaporimeter is evenly distributed with the spray aperture, makes solution can spray evaporator surface uniformly.Be collecting tank under the evaporimeter, the area of collecting tank is bigger slightly than the area of spray thrower, makes the solution of spray can all fall into groove.Sump bottom is emptying solution when lopsidedness is beneficial to discharge opeing.The circulating pump water inlet is arranged on the collecting tank lowest part, and circulating-pump outlet links to each other with circulation pipe.Circulation pipe passes from the air channel and links to each other with the spray thrower inlet.The bottom, air channel of both sides is provided with overfall before and after the collecting tank, and its effect is when the solution overfill or moves in the process solution and overflow through overfall and be discharged to the refrigerator outside, prevents that solution from entering in the casing.One vertical tube is connected to form the linker liquid level gauge by flexible pipe and collecting tank, and densimeter is placed in the vertical tube of liquid level gauge, and liquid level gauge is placed on refrigerator body sidewall and collecting tank co-altitude place.Hold saturated common salt solution in the collecting tank.Ball float and the water compensating valve of being controlled by ball float are arranged in the collecting tank.When liquid level in the collecting tank reduced, ball float was opened water compensating valve by lever, and clear water is mended to go in the collecting tank from storage tank, and after the collecting tank liquid level rose, floating ball lever was closed water compensating valve, stops moisturizing.Lowest part is provided with discharging tube at the bottom of the collecting tank.The collecting tank front and back end all is provided with catches the network of rivers, catches lower end, the network of rivers and is fixed on the collecting tank edge, and the upper end is fixed on the top, air channel.Catch the network of rivers and be made into by fine and closely woven nylon mesh, its effect is the fine droplet that captures in the air-flow of air channel, and is recovered in the collecting tank, enters in the refrigerator body with the solution that prevents saliferous.Storage tank is arranged on the refrigerator top, is connected to the water compensating valve porch of collecting tank by plastic flexible pipe.
In collecting tank, fill it up with saturated common salt solution during use, and in storage tank, fill it up with clear water.When the solution in the collecting tank descended liquid level because of losses such as evaporations, floating ball lever was opened the moisturizing valve, and the water that removes in the water tank is just mended in the collecting tank.Because salt can not evaporate, so lose minimumly, therefore solution can remain saturated solution always in considerable time.In use make regular check on densimeter, when densimeter shows that solution proportion descends to some extent, should in collecting tank, add excessive salt, make solution always saturated.
The present invention has obvious improvement, uses the saturated common salt solution spraying evaporator, and frost-free all the time in the evaporimeter running has improved the performance of refrigeration system, has reduced energy consumption simultaneously; Salt nonhazardous effect, cheap, obtain easily.The present invention is simple in structure, and is easy to manufacture, and spray thrower, collecting tank and all pipelines all can adopt plastics, and be cheap for manufacturing cost, helps large-scale production.
