Abstract
The utility model discloses a kind of two-temperature freezer with constant refrigeration room, comprise the condenser, refrigeration evaporator, refrigerating evaporator and the compressor that are in turn connected into loop, compressor is controlled by freezing temperature controller, also comprises and is arranged on the refrigeration heater in the refrigerating chamber of two-temperature freezer and the magnetic-sensing temperature switch for controlling to refrigerate heater work.The utility model, by increasing the refrigeration heater for heating refrigerating chamber and the magnetic-sensing temperature switch for controlling to refrigerate heater work, not only structural design is relatively simple to make two-temperature freezer, and can the temperature of automatic control and adjustment refrigerating chamber flexibly, and make it under different environments for use, remain on best refrigerated storage temperature.
Description
Technical field
The utility model relates to two-temperature freezer, is specifically related to the two-temperature freezer with constant refrigeration room.
Background technology
The temperature control method of two-temperature freezer is in the market generally with under type: namely by making refrigerating chamber also ensue variations in temperature to the control of freezer temperature.But when reality uses, the difference of gear set by the difference of environment for use temperature and refrigerating chamber temperature controller, the variations in temperature of refrigerating chamber is larger.Through actual measurement, the temperature of refrigerating chamber can change between 13 DEG C ~-5 DEG C, and the cold storing and fresh-keeping effect of refrigerating chamber will be made so greatly to reduce.
Utility model content
Technical problem to be solved in the utility model is the temperature controller adjustment temperature that refrigerating chamber followed by existing two-temperature freezer refrigerating chamber, thus reduces the problem of cold storing and fresh-keeping effect.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of two-temperature freezer with constant refrigeration room, comprise the condenser, refrigeration evaporator, refrigerating evaporator and the compressor that are in turn connected into loop, described compressor is controlled by freezing temperature controller, also comprises the refrigeration heater in the refrigerating chamber being arranged on described two-temperature freezer and the magnetic-sensing temperature switch for controlling the work of described refrigeration heater.
In such scheme, described refrigeration heater and described magnetic-sensing temperature switch form series circuit, and described series circuit is connected to the two poles of the earth of the power supply of described two-temperature freezer.
In such scheme, also comprise touching switch, it is arranged on the door of described two-temperature freezer, and described touching switch is used for controlling described refrigeration heater when described two-temperature freezer opens the door and stops heating.
The utility model, by increasing the refrigeration heater for heating refrigerating chamber and the magnetic-sensing temperature switch for controlling to refrigerate heater work, not only structural design is relatively simple to make two-temperature freezer, and can the temperature of automatic control and adjustment refrigerating chamber neatly, and make it under different environments for use, remain on best refrigerated storage temperature.
Accompanying drawing explanation
Fig. 1 is refrigeration system schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail.
As shown in Figure 1, the two-temperature freezer of what the utility model provided have constant refrigeration room comprises condenser 4, refrigeration evaporator 5, refrigerating evaporator 6, compressor 7 and controls the freezing temperature controller 1 of compressor 7, also comprise and be arranged on the refrigeration heater 3 in the refrigerating chamber of two-temperature freezer and the magnetic-sensing temperature switch 2 for controlling to refrigerate heater 3 work, the input port of condenser 4 is connected to the blast pipe of compressor 7, and the delivery outlet of condenser 4 is connected to the inflow port of refrigeration evaporator 5; The outflow port of refrigeration evaporator 5 is connected to the inflow port of refrigerating evaporator 6, and the outflow port of refrigerating evaporator 6 is connected to the air intake duct of compressor 7, realizes refrigeration evaporator 5 and refrigerating evaporator 6 shares; Refrigeration heater 3 forms series circuit with temperature sensitive switch 2, series circuit is connected to the two poles of the earth of the power supply of two-temperature freezer, the lead-out wire of two contacts of freezing temperature controller 1 is connected to the two poles of the earth of power supply, and for controlling compressor 7 start-stop, magnetic-sensing temperature switch 2 controls the temperature of refrigerating chamber.
During use first under room temperature environment, connected by freezing temperature controller 1, freezer temperature reduces, and temperature of refrigerating chamber is along with reduction, and when temperature of refrigerating chamber is lower than 2 DEG C, magnetic-sensing temperature switch 2 is connected automatically, and refrigeration heater 3 works, and heats to refrigerating chamber; When temperature of refrigerating chamber is increased to about 5 DEG C, magnetic-sensing temperature switch 2 disconnects, and stops heating, thus make cold store temperature remain on change between 3 DEG C ~ 6 DEG C, therefore no matter refrigerator opening time how long, temperature of refrigerating chamber all can be constant in 3-6 DEG C, and can not by the impact of freezer temperature change.Magnetic-sensing temperature switch in present embodiment 2 and refrigeration heater 3 all can with prior art with the use of.
The utility model also comprises touching switch, and it is arranged on the door of two-temperature freezer, and touching switch is used for the Synchronization Control refrigeration heater 3 when two-temperature freezer opens the door and stops heating, and when avoiding further opening the door, temperature raises too fast, and touching switch adopts prior art.
The utility model, structure is simple, with low cost, control reliable, by increasing the refrigeration heater 3 for heating refrigerating chamber and the magnetic-sensing temperature switch 2 for controlling to refrigerate heater 3 work, not only structural design is relatively simple to make two-temperature freezer, and can the temperature of automatic control and adjustment refrigerating chamber flexibly, and makes it under different environments for use, remain on best refrigerated storage temperature.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
