More specifically, first transfer valve 30 and second transfer valve 40 all are magnetic valves.Because magnetic valve has that cost is low, specification extensively and comprehensively, so by first transfer valve 30 and second transfer valve 40 all are made as magnetic valve, thereby can reduce the manufacturing cost of refrigeration system 1.
Refrigerator according to the utility model embodiment is described below.This refrigerator comprises casing, door body, refrigeration system 1 and controller.
Have refrigerating chamber, refrigerating chamber and temperature-changing chamber in the casing.The door body is installed on the casing, is used to open and close refrigerating chamber, refrigerating chamber and temperature-changing chamber.Wherein refrigerating evaporator 50 is used for the refrigerating chamber refrigeration to refrigerator, and refrigeration evaporator 60 is used for the refrigerating chamber refrigeration to refrigerator, and alternating temperature evaporimeter 70 is used for the temperature-changing chamber refrigeration to refrigerator.Controller links to each other with compressor 10, first transfer valve 30 and second transfer valve 40 respectively, with temperature according to refrigerating chamber, refrigerating chamber and the temperature-changing chamber of refrigerator, and the operation of control compressor 10 and first transfer valve 30 and second transfer valve 40.
Refrigerator according to the utility model embodiment, the switching of first and second transfer valves by refrigeration system 1, can switch the cold-producing medium circulation, can realize multiple cold-producing medium circulating path, reach the different refrigeration of refrigerating chamber, refrigerating chamber and the temperature-changing chamber of refrigerator.
Particularly, the user can utilize controller to come the operation of first transfer valve 30 and second transfer valve 40 is controlled as required, reaches the different refrigeration of refrigerating chamber, refrigerating chamber and temperature-changing chamber, can make the use of refrigerator convenient thus.
Certainly, need to prove here that controller can so that come the operation of first transfer valve 30 and second transfer valve 40 is controlled at user's difference input, can make the more convenient to operate of refrigerator thus by presetting control program.
In addition, not only can be user's demand input for the control of first transfer valve 30 and second transfer valve 40 input, also can be the temperature input of refrigerating chamber, refrigerating chamber and the temperature-changing chamber of refrigerator.Thus, refrigerator can automatically be controlled the operation of first transfer valve 30 and second transfer valve 40 according to the temperature of refrigerating chamber, refrigerating chamber and temperature-changing chamber, switches to more rationally, more energy-conservation cold-producing medium endless form.
Correspondingly, in a specific embodiment of the present utility model, refrigerator also comprises Temperature Detector, this Temperature Detector is used to detect the temperature in refrigerating chamber, refrigerating chamber and the temperature-changing chamber, and the temperature value of being surveyed is transferred in the controller, so that controller calculates optimum cold-producing medium endless form according to institute's side temperature value, and control the operation of first transfer valve 30 and second transfer valve 40.Can make refrigerator intelligent more thus, use convenient, more energy-conservation.
Advantageously, refrigerator also can comprise temperature indicating device, and temperature indicating device links to each other with Temperature Detector to show the temperature in refrigerating chamber, refrigerating chamber and the temperature-changing chamber.By temperature indicating device and Temperature Detector are set, thereby can make the user see temperature in the detected refrigerating chamber of Temperature Detector, refrigerating chamber and the temperature-changing chamber by temperature indicating device, thus, can make the user can understand the interior temperature range of refrigerating chamber, refrigerating chamber and temperature-changing chamber of refrigerator more intuitively.Simultaneously also helping the user monitors and controls the temperature in refrigerating chamber, refrigerating chamber and the temperature-changing chamber of refrigerator.Therefore, can make the use of refrigerator convenient.
In the description of this specification, concrete feature, structure, material or characteristics that the description of reference term " embodiment ", " some embodiment ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means in conjunction with this embodiment or example description are contained at least one embodiment of the present utility model or the example.In this manual, the schematic statement to above-mentioned term not necessarily refers to identical embodiment or example.And concrete feature, structure, material or the characteristics of description can be with the suitable manner combination in any one or more embodiment or example.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: can carry out multiple variation, modification, replacement and modification to these embodiment under the situation that does not break away from principle of the present utility model and aim, scope of the present utility model is limited by claim and equivalent thereof.
