Abstract
The utility model relates to an electronic vacuum sterilizing fresh-keeping energy-saving refrigerator, which comprises a compression refrigeration system which is composed of a refrigeration compressor, a temperature sensing assembly, an evaporator, a condenser, and a vacuum heat insulating layer. The utility model is characterized in that the refrigerator is divided into an upper layer, a middle layer, and a lower layer, namely, a vacuum refrigerating zone, a vacuum sterilizing zone, and an electromechanical device zone. The inner part of the vacuum sterilizing zone is provided with an ozone generator which is controlled by an electronic control circuit, and the electromechanical device zone is provided with a vacuum pumping system which is controlled by the electronic control circuit. The vacuum pumping system is formed by that a vacuum pump is connected with index pressure valves by vacuum pumping pipes through a pressure stabilizing box and a vacuum meter, and the index pressure valves are respectively arranged in the vacuum refrigerating zone and the vacuum sterilizing zone. A vacuum fresh-keeping zone of the upper layer of the utility model is used for refrigerating food, and the vacuum sterilizing fresh-keeping cabinet of the lower layer is used for storing the food and tableware. The food which needs to be refrigerated can be sterilized first, and then can be refrigerated. The inner part of the refrigerator has the advantages of high efficiency, sterilization, fresh keeping, and refrigeration. The refrigerator thoroughly stops external air pollution sources, and ensures the nutrition and the freshness of various foods.
Description
Technical field
The utility model relates to a kind of refrigerator, particularly a kind of electronic vacuum sterilization fresh energy-saving refrigerator.
Background technology
Its cold storage cabinet of needs that the function of general refrigerator in the market can not satisfy the modern life far away can not carry out sterilization treatment to the food that stores in the refrigerator, because the general refrigerator technology is limit, only possess general fresh-keeping function, can not accomplish fresh-keeping for a long time.
Summary of the invention
The purpose of this utility model provides a kind of electronic vacuum sterilization fresh energy-saving refrigerator that can provide permanent fresh-keeping and possess sterilizing function.
The purpose of this utility model is achieved through the following channels: electronic vacuum sterilization fresh energy-saving refrigerator, it comprises by refrigeration compressor, the temperature-sensitive assembly, evaporimeter, the compression refrigerating system that condenser and vacuum heat-insulating layer are formed, it is characterized in that this refrigerator is divided into, in, following three floor: vacuum freezing district, vacuum sterilization district and electromechanical equipment district, ozone generator by electronic control circuit control is installed in the vacuum sterilization district, the electromechanical equipment district is equipped with the pumped vacuum systems of electronic control circuit control, and it is connect by evacuation tube through pressurizer tank and vacuum meter by vavuum pump, and the index pressure valve that is installed in respectively in vacuum freezing district and the vacuum sterilization district forms; Above-mentioned electronic control circuit is to connect input circuit meets microswitch SS1 again through output circuit input by time relay KT, the output of microswitch SS1 meets ozone generator WE through the closing of contact, pressure switch KP connects input circuit meets microswitch SS1, SS2 again through output circuit input, and the output of microswitch SS1, SS2 meets vavuum pump M through the input of contact KP1, the output of contact KP1 through the closing of contact; On the cabinet catch of refrigerator, charge valve is installed.The housing of refrigerator is respectively vacuum heat-insulating layer, foaming layer and shell from inside to outside, and the doorframe on the cabinet door is being equipped with the dual face seals pad with cabinet frame junction.
Vacuum freshness retaining district, the utility model upper strata aims at the usefulness of food refrigeration, lower floor's vacuum sterilization antistaling cabinet aims at the usefulness of food and tableware storage, after can sterilizing earlier, all food that need freeze freezes again, sterilized, fresh-keeping, the refrigeration of refrigerator inside, externally thoroughly stopping air pollution source guarantees the nutrition of various kinds of foods, fresh.The utility model has adopted vaccum thermal insulation technique, and it is the vacuum insulation principle that adopts boiling water vacuum flask inner bag, and adiabatic efficiency is improved more than 5 times, has got rid of air and material conductor, thereby has reached purpose of energy saving.
