Detailed Description
The present embodiment provides a refrigerator 10, and for convenience of description, references to "upper", "lower", "front", "rear", "lateral", etc. orientations are defined in terms of spatial positional relationships of the refrigerator 10 in a normal operating state, and are merely for convenience of description and simplicity of description, rather than indicating or implying that the apparatus or element to be referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

The refrigerator 10 of the present embodiment is specifically described below with reference to fig. 1 to 3.
The refrigerator 10 of the present embodiment includes a case having a freezing chamber 110, a cryogenic chamber 120 and an ice making chamber 130 defined therein, and the refrigerator 10 further includes a freezing evaporator chamber, a freezing evaporator 101 located in the freezing evaporator chamber, a cryogenic evaporator 102 located in the cryogenic evaporator chamber, a cryogenic ice making air supply duct 150 and a first damper 105.
The freezing evaporator 101 is configured to supply cooling capacity to the freezing chamber 110, the cryogenic evaporator 102 is configured to supply cooling capacity to the cryogenic chamber 120, the cryogenic ice making air supply duct 150 communicates the ice making chamber 130 with the cryogenic evaporator chamber through the first damper 105, the first damper 105 is controlled to open and the cryogenic evaporator 102 communicates with the compressor 11 to supply cooling capacity to the ice making chamber 130 with the cryogenic evaporator 102 when the freezing evaporator 101 is in defrosting. The problem that ice cubes are possibly melted and adhered due to the fact that cold cannot be provided for the ice making chamber 130 in the defrosting process of the freezing evaporator 101 is avoided, the quality of the ice cubes is guaranteed, and user experience is improved.
In addition to the cooling capacity of the ice making chamber 130 being supplied from the cryogenic evaporator 102 during defrosting of the freezing evaporator 101, the cooling capacity of the ice making chamber 130 is supplied from the freezing evaporator 101, that is, if the temperature of the ice making chamber 130 rises above a preset ice making temperature during non-defrosting of the freezing evaporator 101, the freezing evaporator 101 supplies cooling to the ice making chamber 130 to make ice of the ice making chamber 130 or maintain a low temperature of the ice making chamber 130.
The refrigerator 10 controls the defrosting time of the freezing evaporator 101 and the defrosting time of the cryogenic evaporator 102 to be staggered through a preset program, so as to avoid the problem that the freezing evaporator 101 and the cryogenic evaporator 102 are simultaneously defrosted and cannot provide cold for the ice making chamber 130.
The refrigerator 10 of the present embodiment further includes a cryogenic air supply duct 140 and a first blower 104, the first blower 104 is disposed in the cryogenic air supply duct 140, the cryogenic air supply duct 140 is configured to communicate the cryogenic evaporator chamber with the cryogenic chamber 120, the cryogenic ice making air supply duct 150 is in communication with the cryogenic air supply duct 140, and when the freezing evaporator 101 is in defrosting, the first blower 104 is controlled to be turned on and configured to cause the air flow cooled by the cryogenic evaporator 102 to enter the ice making chamber 130 sequentially through the cryogenic air supply duct 140 and the cryogenic ice making air supply duct 150, thereby accelerating the air flow circulation and accelerating the ice making speed of the ice making chamber 130.
The first air door 105 should be disposed in the cryogenic ice making air supply duct 150, when the cryogenic chamber 120 needs to be refrigerated and the refrigeration evaporator 101 provides cold energy to the ice making chamber 130, the first air door 105 is controlled to be closed, so that air flow in the cryogenic air supply duct 140 is prevented from entering the cryogenic ice making air supply duct 150, and the cold energy of the cryogenic evaporator 102 is fully used for refrigerating the cryogenic chamber 120, so that the efficiency of the refrigerating system is ensured.
To create an airflow circulation between ice making compartment 130 and cryogenically cooled compartment 120, refrigerator 10 should also include a cryogenically cooled ice making return air duct 160 configured to communicate ice making compartment 130 with the cryogenically cooled evaporator compartment such that return air from ice making compartment 130 is returned to cryogenically cooled by cryogenically cooled evaporator 102.
The cryogenic evaporator chamber and the cryogenic air supply duct 140 can be located at the rear of the cryogenic chamber 120, and the cryogenic ice making air supply duct 150 and the cryogenic ice making return air duct 160 can be respectively arranged to pass through foaming layers at the rear of the cryogenic chamber 120 and the ice making chamber 130 to be communicated with the ice making chamber 130, so that the rear space of the cryogenic chamber 120 and the ice making chamber 130 is fully utilized, and the space occupation is reduced.
In one embodiment, the ice making compartment 130 may be located in the freezing compartment 110, and in particular, the ice making housing 106 is provided in the freezing compartment 110, the ice making housing 106 defines the ice making compartment 130, and the ice making compartment 130 communicates with the freezing compartment 110, that is, the ice making compartment 130 has an opening, and air flow in the freezing compartment 110 may enter the ice making compartment 130. The refrigerator 10 further includes a first freezing air supply duct 111 and a second blower 103, the first freezing air supply duct 111 being provided to communicate the freezing evaporator chamber with the freezing chamber 110 to convey the cold air flow cooled by the freezing evaporator 101 to the freezing chamber 110 by the second blower 103, and to lower the temperature of the ice making chamber 130 while lowering the temperature of the freezing chamber 110.
The cryogenic ice-making air supply duct 150 is connected to the ice-making chamber 130 through the freezing chamber 110 and the ice-making box 106, and the freezing evaporator 101 may be frosted, and the door of the freezing chamber 110 may be not closed, so that the cryogenic evaporator 102 may supply cold to the ice-making chamber 130 when the temperature of the freezing chamber 110 is abnormally increased, in addition to the above-mentioned cold supplied to the ice-making chamber 130 by the cryogenic evaporator 102 during the defrosting of the freezing evaporator 101, at this time, if the freezing evaporator 101 is used to supply cold to the ice-making chamber 130, the cooling rate of the ice-making chamber 130 is slow, and thus, the problem of ice-blocking may occur.
That is, when the temperature of the freezing chamber 110 is greater than the preset temperature, the first damper 105 is controlled to be opened, the cryogenic evaporator 102 is communicated with the compressor 11, and the cold air flow around the cryogenic evaporator 102 enters the ice making chamber 130 through the cryogenic air supply duct 140 and the cryogenic ice making air supply duct 150, thereby rapidly reducing the temperature of the ice making chamber 130, so that the ice cubes that may melt are instantaneously condensed.
Accordingly, when the freezing evaporator 101 is not in the defrosting period or the temperature of the freezing chamber 110 is less than the preset temperature, the first air door 105 should be controlled to be closed, the cryogenic evaporator 102 does not provide cooling capacity for the ice making chamber 130 any more, and the normal air supply of the freezing evaporator 101 is sufficient to meet the requirements of ice making and ice storage of the ice making chamber 130, so that the refrigeration system efficiency is reduced due to the fact that the cryogenic evaporator 102 is used for cooling the ice making chamber 130 to enable the temperature of the ice making chamber 130 to be too low. The first air door 105 is closed, so that the cold air in the ice making chamber 130 can be prevented from flowing through the cryogenic ice making air supply duct 150 and the cryogenic air supply duct 140 to enter the cryogenic chamber 120, and the temperature of the cryogenic chamber 120 is prevented from being affected.
In this embodiment, the inlet end of the sub-ambient air return duct 160 is disposed to communicate with the ice making compartment 130 through the freezing compartment 110 and the ice making housing 106, and the outlet end is disposed to communicate with the sub-ambient evaporator compartment to convey the return air of the ice making compartment 130 to the sub-ambient evaporator compartment.
In the embodiment in which the ice making compartment 130 is located in the freezing compartment 110, in the process that the cryogenic evaporator 102 provides the refrigerating capacity for the ice making compartment 130, since the ice making compartment 130 is communicated with the freezing compartment 110, a small portion of the return air of the ice making compartment 130 can enter the freezing compartment 110, the temperature of the freezing compartment 110 is reduced, and the duration of the freezing compartment 110 kept at or below the set temperature is prolonged, so that the utilization rate of the refrigerating capacity of the cryogenic evaporator 102 is increased, the efficiency of the refrigerating system is improved, and energy conservation is facilitated.
As shown in fig. 1, in the present embodiment, the freezing chamber 110 is located above the deep cooling chamber 120, and the ice making housing 106 is disposed in an upper space of the freezing chamber 110. The freezing evaporator chamber is located at the rear of the freezing chamber 110, and the first freezing air supply duct 111 is located at the rear of the freezing chamber 110 and above the freezing evaporator chamber.

The refrigerator 10 of the present embodiment may further include a refrigerating compartment (not numbered) located at an uppermost portion of the refrigerator body, for example, in the embodiment shown in fig. 1, the refrigerating compartment is located above the freezing compartment 110, the cryogenic compartment 120 is located below the freezing compartment 110, and in the embodiment shown in fig. 2, the refrigerating compartment is located above the ice making compartment 130 and the cryogenic compartment 120, and the freezing compartment 110 is located below the ice making compartment 130 and the cryogenic compartment 120.
The volume of the refrigerating chamber may be greater than the volume of the freezing chamber 110, the volume of the freezing chamber 110 may be greater than the volume of the cryogenic chamber 120, so as to satisfy the use requirement of the user for the refrigerating chamber which is most commonly used and has a larger storage requirement, and the refrigerating chamber is positioned at the uppermost part of the box body, thereby facilitating the operation of the user for storing and taking articles.
The refrigerator 10 further includes a refrigerating evaporator 15 and a refrigerating capillary 16, the solenoid valve 13 has a third outlet end connected to an inlet end of the refrigerating capillary 16, an outlet end of the refrigerating capillary 16 is communicated with an inlet end of the refrigerating evaporator 15, an outlet end of the refrigerating evaporator 15 is communicated with an inlet end of the compressor 11, and when the refrigerating chamber needs to be refrigerated, the solenoid valve 13 is configured to controllably conduct the third outlet end thereof with the inlet end of the refrigerating capillary 16 to supply cold to the refrigerating chamber by using the refrigerating evaporator 15.

For ease of understanding, the present embodiment describes a compression refrigeration cycle system of the refrigerator 10 as follows.
The compressor 11 plays a role in the refrigeration system mainly in absorbing low-temperature low-pressure refrigerant vapor from the evaporator, and finally becomes high-temperature high-pressure vapor after adiabatic compression by the compressor 11.
The condenser 12 functions in the refrigeration system to introduce high-temperature and high-pressure vapor in the compressor 11 into the condenser 12, condense the refrigerant vapor at the same pressure, and dissipate heat to the surrounding medium to convert the refrigerant vapor into a high-pressure and low-temperature refrigerant liquid.
The capillary tube plays a role in the refrigeration system mainly in throttling the medium enthalpy of the capillary tube with the high-pressure low-temperature refrigerant cold liquid, converting the low-temperature refrigerant cold liquid into low-pressure refrigerant vapor, and then sending the refrigerant vapor into the evaporator.
The evaporator mainly boils low-temperature low-pressure refrigerant vapor passing through the capillary tube under the conditions of the evaporator and the like, and the refrigerant vapor absorbs heat of surrounding medium in the boiling process and finally becomes low-temperature low-pressure refrigerant dry saturated vapor.
In summary, the dry saturated gas of the refrigerant in the refrigeration system is compressed into the superheated refrigerant vapor with high temperature and high pressure when passing through the compressor 11, the superheated refrigerant vapor with high temperature and high pressure is condensed into the liquid with high pressure and low temperature in the condenser 12 after passing through the exhaust pipe of the expansion valve piston of the compressor 11, the liquid is then passed through the capillary after passing through the filter (not shown), the low-temperature and low-pressure refrigerant vapor is throttled by the medium enthalpy of the capillary, and then the low-temperature and low-pressure refrigerant boils in the isobaric evaporator to absorb a large amount of external heat to become saturated vapor, thereby realizing the refrigeration process, and finally the refrigerant is sucked into the compressor 11 again for cold circulation.
The aforementioned filter, not shown in the drawings, has one of its functions of filtering impurities such as metal chips, various oxides, dust, etc. in the refrigerating system to prevent the impurities from clogging capillaries or damaging the compressor 11.
Impurities generally come from incomplete cleaning of parts, and the assembly process is not strict, so that external impurities enter a refrigeration pipeline to chemically react with water, air or acidic substances in the system.
Impurities-the possibility of serious wear and even seizing of pistons, cylinders, bearings, etc. once entering the compressor 11; the winding of the man-entering motor is formed at a wiring terminal, so that the insulation of a winding coil can be damaged, and short circuit and breakdown are generated; entering the capillary tube, the capillary tube is very thin in inner diameter, so that the capillary tube is likely to be blocked and is not refrigerated, and impurities are very necessary to be filtered.
The filter has the other function of absorbing residual water in the refrigerating system, preventing ice blockage and reducing the corrosion of the water to the refrigerating system.
The refrigerator 10 of the present embodiment, when the freezing evaporator 101 is in defrosting, the first damper 105 is controlled to be opened, and the cryogenic evaporator 102 communicates with the compressor 11 to supply cold to the ice making chamber 130 using the cryogenic evaporator 102. Thus, the problem that ice cubes are likely to melt and adhere due to the fact that cold cannot be provided for the ice making chamber 130 during defrosting of the freezing evaporator 101 is avoided, and the quality of the ice cubes is guaranteed.
Further, in the refrigerator 10 of the embodiment, when the cryogenic evaporator 102 supplies cold to the ice making chamber 130, the air flow of the ice making chamber 130 may enter the freezing chamber 110, so as to reduce the temperature of the freezing chamber 110, prolong the duration of the freezing chamber 110 at or below the set temperature, thereby increasing the utilization rate of the cold energy of the cryogenic evaporator 102, improving the efficiency of the refrigeration system, and being beneficial to energy saving.
