In this application, the ice maker 500 used is a direct cooling ice maker, and the working principle of the direct cooling ice maker is as follows: the ice making evaporation tube 510 directly contacts with the ice making cells 530 of the ice maker 500, the refrigerant evaporates in the ice making evaporation tube 510 to refrigerate the ice maker 500, the ice making evaporation tube 510 reaches a low temperature of about-30 degrees, the temperature in the ice making cells 530 contacting with the ice making evaporation tube 510 can reach about-15 degrees, further, the ice making evaporation tube 510 cools the water in the ice cells 530, and finally the water becomes ice, when the ice scraping condition is reached, the ice cubes are separated from the ice cells 530 by the heater 560 of the ice maker 500, and then the ice turning rods 540 of the turning mechanism turn the ice out.
In some embodiments of the present application, fans are disposed in the refrigerating chamber and/or the temperature-changing chamber 900, each fan is electrically connected to the controller, and the controller can control the fans of the compartments to start or stop, so as to achieve an effect of equalizing the temperatures of the compartments.
The working process of the invention is as follows: when the compressor 100 is started, the refrigerant is compressed and discharged by the compressor 100, then is cooled by the condenser 200, and then is subjected to loop selection by the switching valve group 300, and at the moment, the refrigerant is distributed by the controller according to the refrigeration requirement;
when ice making is needed, the controller starts the refrigerant transportation circuit and the ice maker 500, the controller controls the switching valve set 300 to be communicated with the refrigerating and refrigerating circuit 400, and when the temperature in the refrigerating chamber is reduced to a preset minimum temperature, the controller controls the switching valve set 300 to be disconnected with the refrigerating and refrigerating circuit 400 and be communicated with the ice making and refrigerating circuit 700;
the operation track of the refrigerant is as follows: compressor 100 → condenser 200 → switching valve group 300 → refrigerating throttling device 410 → refrigerating evaporator 420 → ice maker 500 → freezing evaporator 800, refrigerating evaporator 420, ice maker 500, freezing evaporator 800 are connected in series with ice maker 500, freezing evaporator 800 to perform refrigeration, and refrigeration of all appliances of the system can be realized.
At the beginning of ice making, after the compressor 100 is started, the refrigeration is preferentially satisfied, and after the refrigerant flows out of the refrigeration evaporator 420, the refrigerant flows into the ice making evaporation tube 510 of the ice maker 500, at this time, the temperature of the ice tray 530 of the ice maker 500 is higher than the temperature of the refrigerant at the outlet of the refrigeration evaporator 420, and the ice tray 530 can be cooled continuously with a cooling effect.
When the refrigeration meets the specified temperature, the controller controls the electric control valve to close the refrigeration and refrigeration circuit 400, opens the ice-making and refrigeration circuit 700, and the subsequent ice-making process does not repeat the refrigeration of the refrigeration chamber any more, avoids disturbing the existing ice-making rhythm and state, keeps the low-temperature circuit to make ice all the time, improves the ice-making efficiency, and the running track of the refrigerant at the moment is as follows: compressor 100 → condenser 200 → switching valve set 300 → ice making throttle device 710 → ice making machine 500 → freezing evaporator 800, the refrigerant enters ice making machine 500 for refrigeration through capillary throttling, then enters freezing evaporator 800, realizes refrigeration of freezing chamber while making ice most efficiently.
Because the refrigeration and refrigeration circuit 600 is provided, the operation locus of a part of the refrigerant is as follows: compressor 100 → condenser 200 → switching valve group 300 → temperature changing capillary tube → temperature changing evaporator → ice making machine 500 ice making evaporation tube 510 → freezing evaporator 800, and this circuit realizes only the refrigeration of the freezing chamber and its attached compartments. The system will select this circuit to operate when refrigeration is required for refrigeration and ice maker 500 does not require refrigeration or ice maker 500 is set to an off state.
The control system selects the refrigerating circuit according to the refrigerating priority, and controls the on-off of the fans of the compartments through the ice maker 500, so as to meet the requirements of full-time refrigeration and time-sharing refrigeration of the compartments.
To sum up, the embodiment of the present invention provides a refrigerator, which preferentially meets the requirements of refrigeration when ice making starts, and after the refrigeration is finished, the refrigerant flows into the ice maker 500, and at this time, the temperature of the ice maker 500 is higher than the temperature of the refrigerant at the outlet of the refrigeration and refrigeration circuit 400, so that the ice maker 500 can obtain a cooling effect and continuously cool down; when the refrigeration meets the specified temperature, the controller controls the electric control valve to close the refrigeration and refrigeration circuit 400, opens the ice making and refrigeration circuit 700, and then the subsequent ice making process does not repeat the refrigeration of the refrigerating chamber any more, so as to avoid disturbing the existing ice making rhythm and state, keep the low-temperature circuit to make ice all the time, improve the ice making efficiency, and during the ice making process, the refrigeration can be carried out for about 40 minutes without refrigeration, the refrigerant does not need to be switched to the refrigeration and refrigeration circuit 400, so that the refrigerant is mainly used on the ice making and refrigeration circuit 700, the ice making machine 500 is continuously and continuously refrigerated, after ice blocks are made, the compressor 100 stops, then ice scraping heating-deicing (ice turning) -water discharging-series actions are carried out, an ice making cycle is finished, the compressor 100 is restarted, refrigeration is firstly carried out for refrigeration, when the refrigeration reaches to be close to 0 ℃, the refrigeration is stopped, the refrigeration is naturally raised, and the refrigeration is carried out again until the compressor 100 is started after the next ice making is finished, so that the ice making efficiency is improved.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "center", "vertical", "horizontal", "lateral", "longitudinal", "X-axis direction", "Y-axis direction", "Z-axis direction", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Moreover, some of the above terms may be used in other meanings besides orientation or positional relationship, for example, the term "upper" may also be used in some cases to indicate a certain attaching or connecting relationship.
