Accompanying drawing explanation
Fig. 1 is the structural representation of the even cold refrigerator cooling cycle system of the present invention's intelligence.
Detailed description of the invention
Present invention is disclosed a kind of intelligent even cold refrigerator, the control module that described refrigerator is provided with casing, is arranged on the cooling cycle system in casing and is connected with described cooling cycle system signal.
Be provided with the refrigerating chamber being positioned at top, the temperature-changing chamber being positioned at centre position in described casing, be positioned at the refrigerating chamber of below and be located at the temperature sensor of described refrigerating chamber, described temperature-changing chamber and described refrigerating chamber respectively.Described cooling cycle system comprises compressor 7, condenser 6, device for drying and filtering 5, dew removing tube 4, some capillaries 3, some evaporimeters 2 and the pipeline 1 by the series connection of above-mentioned all parts or parallel connection.Described some evaporimeters 2 comprise the first evaporimeter 21 be located in refrigerating chamber, the second evaporimeter 22 be located in temperature-changing chamber, the 3rd evaporimeter 23 being located at described refrigerating chamber and the 4th evaporimeter 24 be located in temperature-changing chamber.Described some capillaries 3 comprise the first capillary 31 be located in refrigerating chamber, are located at the second capillary 32 in temperature-changing chamber and are located at the three capillary 33 of described refrigerating chamber.Described 4th evaporimeter 24 is located in the rear wall of described temperature-changing chamber, and described second evaporimeter is located in other wall bodies of described temperature-changing chamber, and other sidewalls comprise upper and lower roof and left and right sidewall.
Described 4th evaporimeter 24 of described first evaporimeter 21 of described refrigerating chamber, described temperature-changing chamber and the first capillary 31 to be connected formation first branch road by pipeline 1; Described second evaporimeter 22, described second capillary 32 to be connected formation second branch road by pipeline 1; Described three capillary 31 is connected to form the 3rd branch road with pipeline 1.A control valve 8 being used for controlling the condensing agent in described condenser 6 and flowing to also is provided with in described cooling cycle system.Described control valve 8 is provided with the first valve body 81 be connected by pipeline 1 with the three capillary 33 of the first capillary 31 of described first branch road and described 3rd branch road, the second valve body 82 be connected by pipeline 1 with the second capillary 32 of described second branch road.Described first branch road and described second branch road parallel with one another after, the one end and described device for drying and filtering 5, described condenser 6, described dew removing tube 4 and the compressor 7 that are connected with described control valve 8 are connected in series, described 3rd evaporimeter 23 of one end and described refrigerating chamber and described compressor 7 are connected in series in addition, so form three refrigerating circuits.
Wherein, described first valve body 81 of described control valve 8 is closed the condensing agent controlled in described condenser 6 and is flowed to described first evaporimeter 21 by opening and flow to the 3rd evaporimeter 23 again or directly flow to described 3rd evaporimeter 23 without the first evaporimeter.Described second valve body 82 controls the second evaporimeter 22 whether cold-producing medium flows to described temperature-changing chamber.
In the present invention, by designing two in described temperature-changing chamber, independently the second evaporimeter 22 and the 4th evaporimeter 24 realize the function of the wider full warm area of temperature-changing chamber.In time temperature-changing chamber being set to refrigeration gear, described second valve body 82 to end to stop in described condenser 6 second evaporimeter 22 described in described refrigerant flow direction out, and now the 4th evaporimeter 24 of described temperature-changing chamber controls refrigeration with the first evaporimeter 21 of described refrigerating chamber.When temperature-changing chamber is set to freezing gear, described second valve body 82 is opened and is reached the temperature of setting with by refrigerant flow direction second evaporimeter 22 in described condenser 6 thus rapid refrigeration.In above process, when temperature-changing chamber being arranged on refrigeration gear, utilize the temperature value of temperature sensor senses, correspondence is transferred to control module, thus utilizes control module to control described control valve 8 to control the flow direction of described cold-producing medium.
Such as, control module is set, when temperature sensor collects temperature in described temperature-changing chamber lower than 0 DEG C, force refrigerating chamber stopping, namely the first valve body 81 is forced to end described refrigerant flow direction first evaporimeter, but directly flow through by the 3rd branch road the 3rd evaporimeter 23 that described three capillary 33 flows to described refrigerating chamber again, until when the temperature of temperature sensor collection is higher than 2 DEG C, the normal start-stop recovering refrigerating chamber controls, and namely the first valve body 81 controls described refrigerant flow direction first branch road or the 3rd branch road; When temperature sensor collects temperature in described temperature-changing chamber higher than 10 DEG C, pressure refrigerating chamber is started shooting, namely force the first valve body 81 by described refrigerant flow direction first evaporimeter, end described refrigerant flow direction the 3rd branch road simultaneously, until when the temperature of temperature sensor collection is lower than 8 DEG C, the normal start-stop recovering refrigerating chamber controls, and namely the first valve body 81 controls described refrigerant flow direction first branch road or the 3rd branch road.
In sum, separate with the second evaporimeter 22 also can the 4th evaporimeter 24 of independent operating by being provided with in temperature-changing chamber increase for the even cold refrigerator of the present invention's intelligence, according to the temperature in the temperature-changing chamber of temperature sensor collection, described control valve 8 is controlled by control module simultaneously, thus solve the too high or too low problem of the temperature of temperature-changing chamber when refrigerating gear.The rear wall in addition the 4th evaporimeter 24 being located at described temperature-changing chamber is conducive to naturally flowing down of condensation water, is drained by the osculum bottom inner bag, do not need extra condensation-preventing device also can not affect the use of refrigerator miscellaneous part.
In addition, above embodiment is only for illustration of the present invention and unrestricted technical scheme described in the invention, understanding of this description should based on person of ordinary skill in the field, such as " front and back are run through " refers to and did not run through before installing other parts, again such as to " front ", " afterwards ", " left side ", " right side ", " on ", the description of D score isotropy, although this description reference the above embodiments are to present invention has been detailed description, but, those of ordinary skill in the art is to be understood that, person of ordinary skill in the field still can modify to the present invention or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, all should be encompassed in right of the present invention.
