Abstract
A refrigerator with independent/compound control function pertains to the technical field of refrigerators. An air compressor, a condenser, a filter, a capillary tube 2, a refrigerating chamber evaporator, a capillary tube 3 and a freezing chamber evaporator are arranged on the refrigerating loop with series connection. One outlet of a capillary tube is connected with a tube between the capillary tube 3 and the freezing chamber evaporator. The outlets of the capillary tube 1, the capillary tube 2 and the filter are connected with a three-way electromagnetic valve 1. A three-way electromagnetic valve 2 is arranged on the tube between the refrigerating chamber evaporator and the capillary tube 3. The other interface of the three-way electromagnetic valve 2 is connected with the outlet of freezing chamber evaporator. The three-way electromagnetic valve 1 and the three-way electromagnetic valve 2 are connected with a control panel on the refrigerator. The utility model can achieve three refrigerating modes including single refrigerating mode of refrigerating chamber, single refrigerating mode of freezing chamber and compound refrigerating mode of refrigerating chamber and freezing chamber, so the utility model can meet the requirements of users with energy saving effect.
Description
Technical field
The utility model belongs to the refrigerator technical field, particularly a kind of refrigerator of realizing independence/compound control.
Background technology
Current refrigerator can only be realized the compound-refrigerating control of refrigerating chamber and refrigerating chamber, is in series with compressor 1, condenser 2, filter 3, capillary 24, refrigerator evaporator 5, capillary 36, freezer evaporator 7 on its refrigerating circuit (see figure 1) successively.In the refrigerator running, cold-producing medium is back to compressor from compressor through condenser, filter, capillary two, refrigerator evaporator, capillary three, freezer evaporator, moves in circles, and realizes refrigerating function.This refrigerator must refrigerating chamber and refrigerating chamber work simultaneously, can't close one separately and only make another work, be unfavorable for adjusting the refrigerating appliance function conversion, and with the need and the energy-conservation requirement that realizes.
The utility model content
The utility model purpose is to provide a kind of refrigerator of realizing independence/compound control.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of refrigerator of realizing independence/compound control, be in series with compressor, condenser, filter, capillary two, refrigerator evaporator, capillary three, freezer evaporator in its refrigerating circuit, have that pipeline is connected between a capillary one outlet and capillary three and the freezer evaporator, the import of capillary one, capillary two and filter outlet are connected with three-way magnetic valve one; On refrigerator evaporator and capillary tee joint pipeline three-way magnetic valve two is installed, three-way magnetic valve two another interfaces are connected with the freezer evaporator export pipeline.
Three-way magnetic valve one, three-way magnetic valve two are connected with the refrigerator control panel.
The utility model adopts the single compressor refrigeration system, utilizes two magnetic valves that connect in the system to realize the conversion of refrigerating circuit.When magnetic valve one is in sieves and capillary two on-states, magnetic valve two and is in refrigerator evaporator and capillary three on-states, the cold-producing medium that flows out from sieves is back to compressor through capillary two, refrigerator evaporator, capillary three, freezer evaporator successively, realizes current refrigerator refrigerating chamber and refrigerating chamber compound-refrigerating function; When magnetic valve one is in sieves and capillary two on-states, magnetic valve two and is in refrigerator evaporator and capillary three off-states, the cold-producing medium that flows out from sieves is back to compressor through capillary two, refrigerator evaporator, realizes that refrigerating chamber is closed, refrigerating chamber separate refrigeration function; When magnetic valve one is in sieves and capillary one on-state, magnetic valve two and is in capillary three and compressor off-state, the cold-producing medium that flows out from molecular sieve is back to compressor through capillary one, freezer evaporator successively, realizes that refrigerating chamber is closed, refrigerating chamber separate refrigeration function.
The user can make refrigerator be in the different operating state as required, has both satisfied the refrigeration requirement, can reach energy-saving effect again.
