Description
Technical field
The utility model relates to a kind of refrigerator preventing frosting, is specifically related to a kind of refrigerator system of anti-cell breath frosting, for preventing the cell breath of large volume refrigerator caused by startup-shutdown and frosting.
Background technology
Refrigerator is made up of cabinet, refrigeration system and temperature control equipment.The basic role of cabinet is adiabatic, and the quality of heat-insulating property is directly connected to the heat-insulating property of cabinet.The main composition of refrigeration system, by compressor, condenser, evaporimeter and capillary four part, has a closed circulatory system of one's own.Charged cold-producing medium in system, cold-producing medium is vaporizated into gas by low pressure liquid in evaporimeter, absorbs the heat in refrigerator, and temperature in cabinet is reduced.The cold-producing medium becoming gaseous state is sucked by compressor, and by compressor, it is compressed into the gas of HTHP, then enters condenser.The cold-producing medium constantly space heat release towards periphery of gaseous state, is progressively liquefied as liquid within the condenser.These highly pressurised liquids must flow through capillary, and reducing pressure by regulating flow slowly could flow into evaporimeter, maintain in evaporimeter and vaporize with keeping, absorbing and cooling temperature.Thus, refrigerator utilizes electric energy to do work, and the states of matter by cold-producing medium changes, and the heat around cabinet evaporimeter is transported in condenser and goes to give off outside cabinet, and so go round and begin again constantly circulation, reaches refrigeration object.The Main Function of temperature control equipment is then connect compressor when temperature is too high in cabinet, makes refrigeration system work thus cabinet temperature is declined; When temperature in cabinet is down to the temperature of requirement, make compressor power-off.
In refrigerator process of refrigerastion, usual very fast frosting on wall of inner container, formed frost steam a part from storage food, but be more from external environment leak into steam.Compressor cycle startup-shutdown can cause in case that gas is relative to ambient pressure cyclically-varying, and this phenomenon is in the field of business is called " cell breath " of refrigerator visually.Extraneous steam can be introduced in cabinet by " cell breath ", and traditional refrigerator conveniently opens the door and on gasket, has balance air-vent, accelerates steam to enter, and causes frosting serious.
In order to suppress " cell breath " of refrigerator, usually adopt with the following method:
1. by adding the room pressure change that surge volume reduction startup-shutdown causes;
2. by placing water blocking device around, the steam leaked into refrigerator is dehumidified.
As Chinese patent literature CN103673468A discloses a kind of refrigerator, described refrigerator comprises the resistance frost device for being communicated with inside and outside refrigerator, hinders white device and comprises dehumidification pipe, be filled with dehumidizer in dehumidification pipe, and being provided with waterproof ventilated membrane, waterproof ventilated membrane is arranged inside cabinet.The cabinet of refrigerator is provided with outside opening, the cabinet mouth of refrigerator is provided with inside opening, one end of dehumidification pipe is communicated with outside opening, and the other end is communicated with inside opening.Outside opening is arranged on the cabinet back of refrigerator.Outside opening is provided with the leachy cabinet shell connector of band, inside opening is provided with the leachy cabinet shell connector of band.Dehumidification pipe is connected by flexible pipe with described cabinet mouth connector.Refrigerator of the present utility model, effectively can reduce the frosting degree in cabinet, extends the defrosting cycle of user, can reduce the energy consumption in refrigerator simultaneously.
Method result of use in low capacity refrigerator of above-mentioned two kinds of suppression " cell breath " can accept, and in the Large Copacity refrigerator of more than 200L poor effect, and cause the inferior positions such as equipment complexity is too fat to move, action need manually participates in due to optional equipment, have impact on its applicable effect in Large Copacity refrigerator.
Utility model content
The utility model provides a kind of refrigerator system of anti-cell breath frosting, and main purpose is the frosting problem that specific aim solution Large Copacity refrigerator " cell breath " causes.
A kind of refrigerator system of anti-cell breath frosting, comprise cabinet and for regulating the refrigeration system of temperature in cabinet, described cabinet offers the respiration channel of non-horizontal arrangement on the whole, described refrigerator system is also provided with dehydrating unit, in order to remove the moisture flowed through in the air of respiration channel.
Compressor cycle startup-shutdown can cause in cabinet that gas is relative to ambient pressure cyclically-varying, and this phenomenon is in the field of business is called " cell breath " of refrigerator visually.Extraneous steam can be introduced in cabinet by " cell breath ", and very fast frosting on cabinet inwall.Respiration channel is equipped with opening in cabinet inside and outside wall, in cabinet with the air exchange of external environment.Steam in the environment that dehydrating unit sucks for the refrigerator pressure reduction removed because " cell breath " causes, thus the air in guarantee inflow refrigerator is through drying, avoids because steam enters cabinet generation frost.
As preferably, described refrigeration system comprises compressor, condenser, main restricting element and main evaporator, and this forms the closed circuit of cold-producing medium, in the described closed circuit of described dehydrating unit series connection access, comprise auxiliary restricting element and auxiliary evaporimeter, along refrigerant flow direction, described auxiliary restricting element and auxiliary evaporimeter are successively between condenser and main restricting element.
The utility model utilizes the cold of refrigeration system self, carries out cooling and dehumidifying, does not produce large impact to the refrigeration work of refrigeration system.Respiration channel is non-horizontal arrangement on the whole, with the open height of cabinet inwall higher than the opening with cabinet outer wall, utilizes gravity to carry out water conservancy diversion to the steam in respiration channel.
After compressor start, constant temperature in cabinet declines, pressure in cabinet reduces because of the decline of temperature, thus form pressure reduction in the gateway of respiration channel, dehumidified by auxiliary evaporator cools when damp-heat air in environment is entered in cabinet by respiration channel, condensate water flows out or forms frost and rests on respiration channel under the effect of self gravitation in respiration channel.
When the lowest temperature of temperature in cabinet lower than refrigerator Operation system setting, compressor shutdown, temperature in cabinet rises, pressure also rises thereupon, dry air in cabinet flows in external environment by respiration channel, refrigeration system is inner makes the high temperature refrigerant in condenser arrive auxiliary evaporimeter and main evaporator due to the pressure balance in condenser and auxiliary evaporimeter, thus may a small amount of frost layer on auxiliary evaporimeter outer surface melt away, liquid water is got rid of under gravity, the steam that frost layer melts generation is taken out of in external environment by the dry air in cabinet, the exchange capability of heat of auxiliary evaporimeter is made to return to normal level.In this process, the high temperature refrigerant carrying out condenser by the low temperature dry air in cabinet and frost layer cool, reclaimed cold, produced energy-saving effect.
When temperature in cabinet is increased beyond the temperature upper limit of refrigerator Operation system setting, compressor is opened, and enters into cooling link recited above, so circulates, effectively can prevent frosting, and all work completes automatically.
