Detailed Description
The present invention will be described in detail with reference to the embodiments shown in the drawings, and reference is made to fig. 1 to 5, which are preferred embodiments of the present invention.
Referring to fig. 2, the noise reduction refrigeration system of the refrigerator according to the present embodiment includes a compressor 21, and a condenser 22 and a throttling device 23 sequentially connected to an outlet end of the compressor 21. In the present embodiment, the throttling device 23 is a capillary tube, and in other embodiments of the present invention, the throttling device 23 may be other forms of throttling and pressure reducing elements, which are not specifically listed here.
In the embodiment shown in fig. 2, the noise reduction refrigeration system of the refrigerator further comprises a reversing valve 24, an air-cooled evaporator 25, a fan (not shown in the figure) for driving the cooling capacity of the air-cooled evaporator 25 to flow, and a direct-cooling evaporator 26. Wherein, the reversing valve 24 is connected to the outlet end of the throttling device 23, the air-cooled evaporator 25 and the direct-cooled evaporator 26 are arranged between the reversing valve 24 and the inlet end of the compressor 21 in parallel, and the reversing valve 24 has a first working state for communicating only the throttling device 23 and the air-cooled evaporator 25 and a second working state for communicating only the throttling device 23 and the direct-cooled evaporator 26.
Referring to fig. 2, the outlet end of the throttle device 23 is connected to the inlet end a of the direction valve 24, and the two outlet ends B, C of the direction valve 24 are connected to the air-cooled evaporator 25 and the direct-cooled evaporator 26, respectively. In the first operating state of the diverter valve 24 according to the present embodiment, the inlet end a thereof communicates only with the outlet end B; when the directional valve 24 is in the second operating state, the inlet end a is in communication with only the outlet end C. In particular implementations, to facilitate intelligent control of the directional valve 24, the directional valve 24 is typically a solenoid-operated valve.
The present invention further provides a refrigerator 100, referring to fig. 1, the refrigerator 100 has a freezing chamber 11 and a refrigerating chamber 12, in this embodiment, an air-cooled evaporator 25 and a direct-cooled evaporator 26 are both disposed near the freezing chamber 12; in the specific implementation process, the air-cooled evaporator 25 is disposed on the rear wall of the freezing chamber 12, and the direct-cooled evaporator 26 is disposed on the side wall of the freezing chamber 12.
Based on the above structure of the noise reduction refrigeration system of the refrigerator, the operation mode of the refrigerator 100 can be set according to the habit of the user. When the external noise is relatively loud (such as in the daytime), the reversing valve 24 is switched to the first working state, the refrigerator 100 is cooled in an air cooling mode, and the refrigerator cooled in the air cooling mode has the advantages of no frosting, uniform cooling temperature and the like in the use process. When the user needs a quiet environment (such as at night), the reversing valve 24 can be switched to the second working state, and because the cold air of the direct-cooling evaporator 26 realizes cold energy transfer through natural convection, no fan rotates in the refrigerating process, the noise in the operation process of the refrigerator 100 can be greatly reduced; and there is generally no door opening and closing operation of the refrigerator in an environment where a user desires to be quiet, so that there is no occurrence of moisture entering the inside of the refrigerator 100, and the problem of frosting occurring during the use of the conventional direct-cooling type refrigerator can be avoided. The refrigerator 100 of the present invention has the advantages of both air cooling refrigerator and direct cooling refrigerator, and can overcome the problems of great noise, easy frosting, etc. of traditional air cooling refrigerator and meet the requirement of user well.
As some preferred embodiments of the present invention, referring to fig. 3, 4 and 5, the noise reduction refrigeration system for a refrigerator further includes a refrigeration capacity storage chamber 20 for supplying refrigeration capacity to the direct cooling type evaporator 26 and a cold storage evaporator 27 for refrigerating the refrigeration capacity storage chamber 20, the cold storage evaporator 27 is disposed in parallel with respect to the air-cooled type evaporator 25 between the direction change valve 24 and the inlet end of the compressor 21, and the direction change valve 24 has a third operating state in which it communicates only the throttle device 23 and the cold storage evaporator 27.
As shown in fig. 3, 4 and 5, unlike the structure shown in fig. 2, the direction valve 24 further has an outlet end D, and when the direction valve 24 is in the third operating state, the inlet end a thereof is communicated with only the outlet end D. Based on the design structure, when the compressor 21 operates to refrigerate the freezing chamber 11 and/or the refrigerating chamber 12 of the refrigerator 100, the reversing valve 24 is switched to the third working state, so that the cold storage evaporator 27 can refrigerate, and the cold storage cavity 20 can store the cold generated by the cold storage evaporator 27.
In the specific implementation process, a cold storage medium is filled in the cold storage cavity 20; in addition, referring to fig. 1, the outer wall of the refrigerator 100 is generally filled with the foamed insulation layer 10, and the coldness storage chamber 20 according to the present invention may be embedded in the foamed insulation layer 10, so that the effective storage of coldness can be achieved.
Based on the arrangement of the cold storage chamber 20 and the cold storage evaporator 27, when the user needs an extremely quiet environment, both the compressor 21 of the noise reduction refrigeration system of the refrigerator and the fan driving the cold of the air-cooled evaporator 25 to flow can stop running, and the cold storage chamber 20 provides cold to the direct-cooled evaporator 26 to realize the refrigeration work of the refrigerator. Thus, compared with the structure of the noise-reducing refrigerating system of the refrigerator shown in fig. 2, the refrigerator can further reduce the running noise of the refrigerator.
Referring to fig. 3, the direct-cooling type evaporator 26 and the cold storage evaporator 27 respectively have a first port and a second port (not shown), which are connected to the reversing valve 24, and it is easy to understand that the first port refers to a port at which the direct-cooling type evaporator 26 is connected to the outlet end C of the reversing valve 24, and the second port refers to a port at which the cold storage type evaporator 27 is connected to the outlet end D of the reversing valve 24. In the present embodiment, the direction valve 24 has a fourth operating state in which only the first port and the second port are communicated so that the direct-cooling evaporator 26 and the cold-storage evaporator 27 form an annular circuit therebetween.
As shown in fig. 3, i.e., when the direction valve 24 is in the fourth operating state, communication is established between the outlet end C and the outlet end D of the direction valve 24; in this way, the direct-cooling evaporator 26 and the cold storage evaporator 27 are communicated with each other at both ends thereof, and a circuit is formed therebetween. At this time, the refrigerant media in the direct-cooling evaporator 26 and the refrigerant storage evaporator 27 can flow relatively, so as to realize the transmission of cold energy; specifically, the cold in the cold storage cavity 20 is transferred to the refrigerant medium in the cold storage evaporator 27, and the refrigerant medium in the cold storage evaporator 27 flows to the direct-cooling evaporator 26, so that the cold in the cold storage cavity 20 is transferred to the direct-cooling evaporator 26, thereby implementing the compartment refrigeration operation of the refrigerator 100.
As a preferred embodiment structure of the embodiment shown in fig. 3, the cold storage evaporator 27 in the present embodiment is located above the direct-cooling type evaporator 26. When the compartment of the refrigerator 100 is refrigerated using the cold in the cold storage chamber 20, the cold storage evaporator 27 directly obtains the cold in the cold storage chamber 20, and the direct cooling evaporator 26 is used to transfer the cold to the compartment of the refrigerator 100. In this process, the temperature inside the cold storage evaporator 27 is lower than the temperature inside the direct-cooling evaporator 26, the refrigerant can be liquefied when entering the cold storage evaporator 27 and then automatically flows downward to the direct-cooling evaporator 26, and the refrigerant can be gasified when entering the direct-cooling evaporator 26 and then automatically flows upward to the direct-cooling evaporator 26. The circulation can realize the cold energy in the cold energy storage cavity 20 transferring to the direct cooling evaporator 26 and the refrigeration work of the refrigerator 100.
Referring to fig. 4, in this embodiment, the noise reduction refrigeration system of the refrigerator further includes a heat pipe 28, and the heat pipe 28 has an operating position for connecting the refrigeration storage cavity 20 and the direct-cooling evaporator 26 to transfer the refrigeration in the refrigeration storage cavity 20 to the direct-cooling evaporator 26 and an inactive position for disconnecting the connection between the refrigeration storage cavity 20 and the direct-cooling evaporator 26. That is, in the present embodiment, when the user needs an extremely quiet environment, the heat pipe 28 is brought into the operating position to realize the transfer of the cooling capacity in the cooling capacity storage chamber 20 to the direct-cooling evaporator 26; during the cold accumulation in the cold storage cavity 20, the heat pipe 28 enters the non-working position to block the cold transmission between the cold storage cavity 20 and the direct-cooling evaporator 26.
Referring to fig. 5, in the present embodiment, the difference between the structure of the noise reduction refrigeration system of the refrigerator shown in fig. 4 is: the heat pipe 28 is replaced by a refrigerant circulation pipeline 29, wherein a flowing refrigerant is stored in the refrigerant circulation pipeline 29, the refrigerant circulation pipeline 29 passes through the refrigeration capacity storage cavity 20 and the direct-cooling evaporator 26 to transmit the refrigeration capacity in the refrigeration capacity storage cavity 20 to the direct-cooling evaporator 26, and in the specific implementation process, a pump 290 for driving the refrigerant to flow during operation is connected in the refrigerant circulation pipeline 29.
