Description
Technical field
The utility model relates to technical field of refrigeration equipment, especially a kind of four-temperature region refrigerator.
Background technology
Along with growth in the living standard, many warm areas refrigerator has appearred in the market, these many warm areas refrigerators are at original refrigerating chamber, increased chamber between two on the basis of refrigerating chamber, ice milk chamber and fresh-keeping chamber, the temperature of ice milk chamber generally remains on-1 ℃～-12 ℃, the temperature of fresh-keeping chamber generally is controlled at 0 ℃, the temperature of refrigerating chamber is lower than fresh-keeping chamber, freezer temperature then is lower than the ice milk chamber, for the temperature that keeps each warm area and make the higher refrigerating efficiency of refrigerator performance, the structure of many warm areas refrigerator in the market generally is that the public magnetic valve of evaporimeter indoor between two is connected with condenser and freezes, be that the ice milk chamber is connected with condenser with the public magnetic valve in series connection back, refrigerating chamber chamber, fresh-keeping chamber is connected with condenser with the public magnetic valve in refrigerating chamber series connection back, therefore can not realize independent control to each chamber, start-stop that temperature sensor can control magnetic valve all is installed controlling its temperature in ice milk chamber and the fresh-keeping chamber, this mode can not take into account be in series with it between the temperature of chamber.
The utility model content
The purpose of this utility model is to provide a kind of four-temperature region refrigerator that can control separately the temperature of each chamber.
The technical solution of the utility model is: a kind of four-temperature region refrigerator, comprise refrigerating chamber, the ice milk chamber, refrigerating chamber, four of fresh-keeping chambers independently between chamber and by the compressor that is serially connected, condenser, the refrigeration plant that molecular sieve constituted, each indoor evaporimeter that all has separately is connected with refrigeration plant, the molecular sieve of refrigeration plant is connected with one and advances three and go out magnetic valve, one advances three three branch roads that go out electromagnetic valve outlet connects respectively by capillary: the refrigerating evaporator in the refrigerating chamber, the soft moving evaporimeter that ice milk is indoor, refrigeration evaporator in the refrigerating chamber, refrigeration evaporator is connected in series with fresh-keeping evaporimeter in fresh-keeping chamber, refrigerating evaporator, soft moving evaporimeter, the liquid outlet of fresh-keeping evaporimeter feeds compressor, and also is provided with electric heater unit in fresh-keeping chamber.
Be provided with in the described refrigerating chamber and can control one and advance three and go out the freezing sensor of magnetic valve the start-stop of the cooling branch road of refrigerating chamber; In refrigerating chamber, be provided with and control one and advance three and go out the refrigeration sensor of magnetic valve the start-stop of the cooling branch road of refrigerating chamber; Can control one and advance three and go out the ice milk sensor of magnetic valve indoor being provided with of ice milk, and can control one and advance three and go out magnetic valve and before each the shutdown, again the ice milk chamber is being compensated the cooling compensation sensor the start-stop of the cooling branch road of ice milk chamber; In fresh-keeping chamber, also be provided with control sensor and defrosting sensor with the electric heater unit control connection.
A kind of four-temperature region refrigerator that the utility model is designed, advancing three by one goes out magnetic valve and can control control to the refrigerating capacity of each chamber, at refrigerating chamber that is serially connected and fresh-keeping chamber, because fresh-keeping chamber is temperature required higher, in fresh-keeping chamber, also be provided with electric heater unit, fresh-keeping chamber is adopted the electrical heating compensation way, prevent that temperature is low excessively.Thereby can realize independent control to each chamber.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises the compressor 1 that is serially connected, condenser 2, molecular sieve 3, molecular sieve 3 connections one are advanced three and are gone out magnetic valve 4, one advances three three branch roads that go out magnetic valve 4 outlets connects respectively by capillary 5: the soft moving evaporimeter 9 in the refrigerating evaporator 7 in the refrigerating chamber 6, the ice milk chamber 8, the refrigeration evaporator 11 in the refrigerating chamber 10, refrigeration evaporator 11 is connected in series with fresh-keeping evaporimeter 13 in fresh-keeping chamber 12, the liquid outlet of refrigerating evaporator 7, soft moving evaporimeter 9, fresh-keeping evaporimeter 13 feeds compressor 1, thereby constitutes refrigerating circuit.
In refrigerating chamber 6, be provided with freezing sensor 17, can control one and advance three start-stops that go out the cooling branch road of 4 pairs of refrigerating chambers 6 of magnetic valve.In refrigerating chamber 10, be provided with refrigeration sensor 20, can control one and advance three start-stops that go out the cooling branch road of 4 pairs of refrigerating chambers 10 of magnetic valve.
Be provided with ice milk sensor 18 and compensation sensor 19 in ice milk chamber 8, ice milk sensor 18 can be controlled one and advance three start-stops that go out the cooling branch road of 4 pairs of ice milk chambers 8 of magnetic valve.Compensation sensor 19 can be controlled one and advance three and go out magnetic valve 4 again ice milk chamber 8 is being compensated cooling before each the shutdown, realizes that ice milk chamber 8 can not require start separately.
In fresh-keeping chamber 12, also be provided with electric heater unit 14 and with control sensor 15, the defrosting sensor 16 of electric heater unit 14 control connections, when the temperature of fresh-keeping chamber 12 is crossed when low, defrosting sensor 16 control electric heater units 14 start, when temperature reached requirement, control sensor 15 control electric heater units 14 cut out.
