[0073] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0074] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature.

[0075] For refrigerators, in order to remove condensed frost and ice on the evaporator, a defrost heater is generally used to heat and defrost, and remove condensed frost and ice on the evaporator.

[0076] In the related art, the frost or ice conditions of the evaporators in different installation cavities of the refrigerator are different. When a defrost heater is used for heating and defrosting, the defrosting time of different evaporators in different installation cavities is different, resulting in inconsistent defrosting progress, which affects the performance of the refrigerator.

[0077] like Figure 1 to Figure 2As shown, an embodiment of the present application provides a refrigerator, comprising: a cabinet 100, at least two evaporators, and at least two heating elements; wherein the cabinet 100 has at least two installation cavities; the two evaporators are respectively arranged in the two installation cavities; the two heating elements are respectively arranged in the two installation cavities; among the two evaporators and the two heating elements, one of the heating elements is connected to one of the evaporators, and the other heating element is connected to the other evaporator; the two heating elements are adapted to be turned on or off at the same time.

[0078] It can be understood that when the two heating elements are turned on at the same time, the two heating elements can defrost or defrost the two evaporators at the same time; when the two heating elements are turned off at the same time, the defrosting progress of the two heating elements can be consistent, thereby improving the performance of the refrigerator.

[0079] The installation cavity provided in the embodiment of the present application includes at least one first installation cavity 101 and at least one second installation cavity 102, the first installation cavity 101 and the second installation cavity 102 are arranged at intervals, and the internal temperature of the first installation cavity 101 is higher than the internal temperature of the second installation cavity 102; the evaporator includes at least one first evaporator 200 and at least one second evaporator 300, the first evaporator 200 is arranged in the first installation cavity 101; the first evaporator 200 can transport a first amount of cold toward the first installation cavity 101 under the drive of a first external force; the second evaporator 300 is arranged in the second installation cavity 102; the second evaporator 300 can transport a second amount of cold toward the second installation cavity 102 under the drive of a second external force.

[0080] It can be understood that the first evaporator 200 can transport the first cooling capacity toward the first installation cavity 101 driven by a first external force, thereby reducing the internal temperature of the first installation cavity 101; the second evaporator 300 can transport the second cooling capacity toward the second installation cavity 102 driven by a second external force, thereby reducing the internal temperature of the second installation cavity 102.

[0081] The heating element provided in the embodiment of the present application includes at least one first heating element 400 and at least one second heating element 500. The first heating element 400 is arranged in the first installation cavity 101, and the first heating element 400 and the first evaporator 200 are arranged at intervals; the second heating element 500 is arranged in the second installation cavity 102, and the second heating element 500 and the second evaporator 300 are arranged at intervals; the first heating element 400 and the second heating element 500 are electrically connected.

[0082] It should be noted that when the first evaporator 200 is working, the temperature of the surface of the first evaporator 200 is lower than the internal temperature of the box body 100, and the water vapor in the box body 100 will liquefy and condense on the surface of the first evaporator 200. After condensation, the water vapor will solidify and adhere to the surface of the first evaporator 200 when the first evaporator 200 continues to work, thereby causing the refrigeration effect of the first evaporator 200 to deteriorate.

[0083] It should be noted that when the first heating element 400 is working, the surface temperature of the heating element is higher than the internal temperature of the cabinet 100, and heat exchange occurs between the heating element and the inside of the cabinet 100, thereby increasing the internal temperature of the cabinet 100. When the internal temperature of the cabinet 100 increases, ice attached to the surface of the first evaporator 200 absorbs heat and liquefies into water. Under the action of gravity, the liquefied water moves downward along the surface of the first evaporator 200 and drips from the bottom of the first evaporator 200.

[0084] It is understandable that when the first heating element 400 is working, the first evaporator 200 stops working to improve the defrosting or ice-melting efficiency of the first evaporator 200 .

[0085] It should be noted that when the second evaporator 300 is working, the temperature of the surface of the second evaporator 300 is lower than the internal temperature of the box body 100, and the water vapor in the box body 100 will liquefy and condense on the surface of the second evaporator 300. After condensation, the water vapor will solidify and adhere to the surface of the second evaporator 300 when the second evaporator 300 continues to work, thereby causing the refrigeration effect of the second evaporator 300 to deteriorate.

[0086] It should be noted that when the second heating element 500 is working, the surface temperature of the heating element is higher than the internal temperature of the cabinet 100, and heat exchange occurs between the heating element and the inside of the cabinet 100, thereby increasing the internal temperature of the cabinet 100. When the internal temperature of the cabinet 100 increases, ice attached to the surface of the second evaporator 300 absorbs heat and liquefies into water. Under the action of gravity, the liquefied water moves downward along the surface of the second evaporator 300 and drips from the bottom of the second evaporator 300.

[0087] It is understandable that when the second heating element 500 is working, the second evaporator 300 stops working to improve the defrosting or ice-melting efficiency of the second evaporator 300 .

[0088] It should be noted that the first heating element 400 and the second heating element 500 are electrically connected. When the first heating element 400 is powered on, the second heating element 500 is also powered on. The first heating element 400 and the second heating element 500 defrost or defrost the first evaporator 200 and the second evaporator 300 respectively, thereby reducing the defrosting or defrosting time of the first evaporator 200 and the second evaporator 300 to improve the defrosting or defrosting efficiency of the first evaporator 200 and the second evaporator 300.

[0089] It should be noted that the first heating element 400 and the second heating element 500 are electrically connected. When the first heating element 400 is powered off and does not work, the second heating element 500 is also powered off and does not work, thereby reducing the difficulty of controlling the first heating element 400 and the second heating element 500.

[0090] like Figure 3 to Figure 4 As shown, in the refrigerator provided in an embodiment of the present application, in the height direction of the box body 100, the first installation cavity 101 and the second installation cavity 102 are spaced apart, that is, one of the first installation cavity 101 and the second installation cavity 102 is located above the other of the first installation cavity 101 and the second installation cavity 102.

[0091] It should be noted that, when the first installation cavity 101 and the second installation cavity 102 are spaced apart in the height direction of the housing 100 , the first evaporator 200 and the second evaporator 300 are spaced apart, and the first heating element 400 and the second heating element 500 are spaced apart.

[0092] It should be noted that, when one of the first mounting cavity 101 and the second mounting cavity 102 is located above the other of the first mounting cavity 101 and the second mounting cavity 102, the first mounting cavity 101 and the second mounting cavity 102 have a variety of installation methods, and the installation methods of the first mounting cavity 101 and the second mounting cavity 102 are exemplified below.

[0093] like Figure 5 to Figure 6 As shown, in a feasible implementation manner, the first installation cavity 101 is located above the second installation cavity 102 , the first evaporator 200 is located above the second evaporator 300 , and the first heating element 400 is located above the second heating element 500 .

[0094] In another feasible implementation, the first installation cavity 101 is located below the second installation cavity 102 , the first evaporator 200 is located below the second evaporator 300 , and the first heating element 400 is located below the second heating element 500 .

[0095] It is understandable that there is no limitation on the installation method between the first installation cavity 101 and the second installation cavity 102 , and it can be selected according to actual use requirements.

[0096] It should be noted that, when the internal temperature of the first installation cavity 101 is higher than the internal temperature of the second installation cavity 102, the surface temperature of the first evaporator 200 is higher than the surface temperature of the second evaporator 300, and per unit time, the volume of frost or ice condensed on the surface of the first evaporator 200 is smaller than the volume of frost or ice condensed on the surface of the second evaporator 300.

[0097] like Figures 7 and 8 As shown, it can be understood that, when the surface temperature of the first evaporator 200 is higher than the surface temperature of the second evaporator 300, the volume of frost generated on the surface of the second evaporator 300 or ice generated by condensation is greater than the volume of frost generated on the surface of the first evaporator 200 or ice generated by condensation; the second heating element 500 can melt the frost generated on the surface of the second evaporator 300 or ice generated by condensation, and the first heating element 400 can melt the frost generated on the surface of the first evaporator 200 or ice generated by condensation.

[0098] It should be noted that the rated power of the first heating element 400 is less than or equal to the rated power of the second heating element 500, that is, the surface temperature of the second heating element 500 is greater than or equal to the surface temperature of the first heating element 400, which can make the defrosting or de-icing efficiency of the surface of the second evaporator 300 higher than or equal to the defrosting or de-icing efficiency of the surface of the first evaporator 200, thereby reducing the defrosting or de-icing time of the surface of the second evaporator 300, so that the defrosting or de-icing time of the first evaporator 200 and the second evaporator 300 tend to be the same, thereby improving the defrosting or de-icing efficiency of the first evaporator 200 and the second evaporator 300, thereby protecting the refrigerator and extending the service life of the refrigerator.

[0099] The embodiment of the present application provides a plurality of first installation cavities 101 , wherein two adjacent first installation cavities 101 are spaced apart from each other, wherein the internal temperature of a first first installation cavity 101 is greater than or equal to the internal temperature of a second first installation cavity 101 .

[0100] It should be noted that there are many different arrangements of two adjacent first installation cavities 101 . The arrangement of two adjacent first installation cavities 101 is described below with examples.

[0101] In a feasible implementation, in the height direction of the box body 100 , two adjacent first installation cavities 101 are arranged at intervals, wherein a first first installation cavity 101 is located above a second first installation cavity 101 .

[0102] In another feasible implementation, in the height direction of the vertical box body 100 , two adjacent first installation cavities 101 are spaced apart.

[0103] It is understandable that there is no limitation on the arrangement of two adjacent first installation cavities 101 , and the arrangement can be selected according to actual use requirements.

[0104] It should be noted that, when there are multiple first installation cavities 101 , the first evaporator 200 and the first heating element 400 can be arranged in a variety of different ways. The following describes the arrangement of the first evaporator 200 and the second heating element 500 in turn with examples.

[0105] In a feasible implementation manner, a plurality of first evaporators 200 are provided, two adjacent first evaporators 200 are arranged at intervals, and a first installation cavity 101 and a first evaporator 200 are arranged in coordination.

[0106] In another feasible implementation manner, a plurality of first heating elements 400 are provided, two adjacent first heating elements 400 are arranged at intervals, and a first installation cavity 101 and a first heating element 400 are arranged in coordination.

[0107] In addition, in other feasible embodiments, a plurality of first evaporators 200 are provided, two adjacent first evaporators 200 are arranged at intervals, and a first installation cavity 101 and a first evaporator 200 are arranged in coordination with each other; a plurality of first heating elements 400 are provided, two adjacent first heating elements 400 are arranged at intervals, and a first installation cavity 101 and a first heating element 400 are arranged in coordination with each other.

[0108] It is understandable that, in the case where a plurality of first installation cavities 101 are provided, there is no limitation on the arrangement of the first evaporator 200 and the first heating element 400 , and they can be selected according to actual use requirements.

[0109] It should be noted that when multiple first heating elements 400 are provided, the multiple first heating elements 400 are electrically connected, thereby reducing the defrosting or defrosting time of the multiple first evaporators 200 to improve the defrosting or defrosting efficiency of the multiple first evaporators 200 .

[0110] It should be noted that when the internal temperature of the first first installation cavity 101 is greater than or equal to the internal temperature of the second first installation cavity 101 , the rated power of the first first heating element 400 is less than or equal to the rated power of the second first heating element 400 .

[0111] It should be noted that, when the internal temperature of the first first installation cavity 101 is greater than or equal to the internal temperature of the second first installation cavity 101, the surface temperature of the first first evaporator 200 corresponding to the first first installation cavity 101 is greater than or equal to the surface temperature of the second first evaporator 200 corresponding to the second first installation cavity 101; the rated power of the first first heating element 400 arranged in conjunction with the first first evaporator 200 is less than or equal to the rated power of the second first heating element 400 arranged in conjunction with the second first evaporator 200.

[0112] It can be understood that the surface temperature of the second first heating element 400 is greater than or equal to the surface temperature of the first first heating element 400, thereby reducing the defrosting or defrosting time of the first first evaporator 200 and the second first evaporator 200 to improve the defrosting or defrosting efficiency of the first first evaporator 200 and the second first evaporator 200.

[0113] The embodiment of the present application provides a plurality of second installation cavities 102 , where two adjacent second installation cavities 102 are spaced apart, and the internal temperature of a first second installation cavity 102 is greater than or equal to the internal temperature of a second second installation cavity 102 .

[0114] It should be noted that there are many different arrangements of two adjacent second installation cavities 102 . The arrangement of two adjacent second installation cavities 102 is described below with examples.

[0115] In a feasible implementation, in the height direction of the box body 100 , two adjacent second installation cavities 102 are spaced apart, wherein the first second installation cavity 102 is located above the second second installation cavity 102 .

[0116] In another feasible implementation, in the height direction of the vertical box body 100 , two adjacent second installation cavities 102 are spaced apart.

[0117] It is understandable that there is no limitation on the arrangement of two adjacent second installation cavities 102 , and the arrangement can be selected according to actual use requirements.
