Description

Technical Field

[0001] The embodiments of the present application relate to refrigerator technology, and more particularly to a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that keeps a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. The refrigerator is equipped with different temperature storage areas to better meet the family's storage needs for various foods and improve the preservation and storage efficiency of food.

[0003] The realization of different temperature zones on the refrigerator mainly depends on the different distances between the evaporator and different temperature zone storage areas. The distance between the temperature zone storage area relatively closer to the evaporator and the evaporator is shorter, and the distance between the temperature zone storage area relatively farther from the evaporator and the evaporator is longer.

[0004] Therefore, the temperature zone storage area located relatively closer to the evaporator has a first temperature, and the temperature zone storage area located relatively farther away from the evaporator has a second temperature, and the first temperature is lower than the second temperature; resulting in the temperature zone storage area located relatively farther away from the evaporator having the problem of long cooling time and low cooling efficiency.

[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] The refrigeration structure of the refrigerator is mainly composed of a compressor, a condenser, a throttle valve and an evaporator which are connected end to end in sequence, wherein the compressor, the condenser, the throttle valve and the evaporator are connected by connecting pipes, and refrigerant is circulated in the compressor, the condenser, the throttle valve, the evaporator and the connecting pipes.

[0076] It should be noted that the fluid movement of the refrigerant is shown in the following steps:

[0077] Step 1: Low-temperature and low-pressure refrigerant gas comes out of the evaporator and enters the inlet of the compressor. The compressor compresses the refrigerant gas into high-temperature and high-pressure gas, which is then discharged through the outlet.

[0078] Step 2: High-temperature and high-pressure refrigerant gas comes out of the compressor and enters the inlet of the condenser. In the condenser, the refrigerant gas dissipates heat through the heat sink and fan, gradually cools and condenses into high-pressure liquid. The condensed high-pressure liquid refrigerant flows out from the outlet of the condenser.

[0079] Step 3: High-pressure liquid refrigerant comes out of the condenser and enters the inlet of the throttle valve. In the throttle valve, the refrigerant liquid passes through a small hole or expansion device, the pressure drops suddenly, and it expands rapidly and becomes a low-temperature and low-pressure liquid.

[0080] Step 4: The low-temperature and low-pressure liquid refrigerant comes out of the throttle valve and enters the inlet of the evaporator. In the evaporator, the refrigerant absorbs the heat inside the refrigerator and gradually evaporates into gas. This process causes the temperature inside the refrigerator to drop. The evaporated low-temperature and low-pressure refrigerant gas flows out from the outlet of the evaporator.

[0081] Step 5: The evaporated low-temperature and low-pressure refrigerant gas enters the inlet of the compressor again through the connecting pipe.

[0082] It should be noted that the temperature of the surface of the evaporator is lower than the internal temperature of the refrigerator, and heat exchange occurs between the surface of the evaporator and the interior of the refrigerator, causing the internal temperature of the refrigerator to drop.

[0083] In the related art, the refrigerator is provided with a refrigerating chamber, a temperature-changing chamber and a freezing chamber, wherein the temperature of the refrigerating chamber is greater than or equal to the temperature of the temperature-changing chamber, and the temperature of the temperature-changing chamber is greater than the temperature of the freezing chamber. The setting of the refrigerating chamber, the temperature-changing chamber and the freezing chamber can enable the refrigerator to better meet the family's storage needs for various foods and improve the preservation effect and storage efficiency of food.

[0084] It should be noted that during the processing of the refrigerator, the position with a relatively lower temperature is closer to the evaporator, and the position with a relatively higher temperature is farther away from the evaporator. That is, in the refrigerating chamber, the variable temperature chamber and the freezing chamber; the gap between the freezing chamber and the evaporator, the gap between the variable temperature chamber and the evaporator, and the gap between the refrigerating chamber and the evaporator increase in sequence.

[0085] It can be understood that the cold energy generated by the evaporator first reaches the freezing chamber, then reaches the temperature changing chamber, and finally reaches the refrigerating chamber.

[0086] It should be noted that since the cooling capacity generated by the evaporator is limited, in actual use, the variable temperature room and cold storage room located relatively far away from the evaporator have the problems of long cooling time and low cooling efficiency.

[0087] like Figure 1 to Figure 2As shown, an embodiment of the present application provides a refrigerator, which includes: a box body 100, the box body 100 is formed with a first chamber 101, a second chamber 102 and an installation cavity 103, the first chamber 101 and the second chamber 102 are located on one side of the box body 100, and the installation cavity 103 is located on the other side of the box body 100; the internal temperature of the first chamber 101 is lower than the internal temperature of the second chamber 102.

[0088] It should be noted that, in the first chamber 101 and the second chamber 102, the first chamber 101 has a variety of different configurations, and the second chamber 102 has a variety of different configurations. The configurations of the first chamber 101 and the second chamber 102 are described below with examples in turn.

[0089] In a feasible implementation manner, the first chamber 101 is a freezing chamber, and the second chamber 102 is a refrigerating chamber.

[0090] In another feasible implementation, the first chamber 101 is a temperature-changing chamber, and the second chamber 102 is a refrigerating chamber.

[0091] like Figure 3 As shown, in addition to this, in other feasible implementations, the first chamber 101 is a freezing chamber, and the second chamber 102 is a temperature-changing chamber.

[0092] It is understandable that there is no limitation on the specific configuration of the first chamber 101 and the second chamber 102 , and they can be selected according to actual use requirements, as long as the internal temperature of the first chamber 101 is lower than the internal temperature of the second chamber 102 .

[0093] like Figures 4 to 5 As shown, it should be noted that the first chamber 101 and the second chamber 102 are located on the side of the box body 100 close to the box opening, and the installation chamber 103 is located on the side of the box body 100 away from the box opening; the first chamber 101 and the second chamber 102 are used to place the items to be stored, and the installation chamber 103 is used to accommodate the evaporator 200.

[0094] like Figure 6 to Figure 7 As shown, it should be noted that the refrigerator provided in the embodiment of the present application also includes: the first chamber 101 has a first air inlet 1011 and a first air outlet 1012, and the second chamber 102 has at least one second air inlet 1021; the evaporator 200 is arranged in the installation cavity 103, and the installation cavity 103 is connected with the first chamber 101 through the first air inlet 1011; the connecting piece 300 is arranged in the installation cavity 103; one end of the connecting piece 300 is connected with the first chamber 101 through the first air outlet 1012, and the other end of the connecting piece 300 is connected with the second chamber 102 through the second air inlet 1021.

[0095] It is understandable that the cold energy generated by the evaporator 200 is guided to the installation cavity 103 and then guided to the first chamber 101 through the first air inlet 1011 to drive the internal temperature of the first chamber 101 to decrease.

[0096] It is understandable that the cold energy in the first chamber 101 is guided to the connecting piece after passing through the first air outlet 1012 , and then passes through the connecting piece through the second air inlet 1021 and is guided to the second chamber 102 , so as to reduce the internal temperature of the second chamber 102 .

[0097] like Figure 8 As shown, it should be noted that the evaporator 200 and the connecting piece are separately arranged in the installation cavity 103, and the surface temperature of the connecting piece is lower than the surface temperature of the evaporator 200. The connecting piece and the evaporator 200 exchange heat, so that the surface temperature of the connecting piece is reduced, thereby driving the internal temperature of the second chamber 102 to decrease.

[0098] It can be understood that the evaporator 200 and the connecting parts are separately arranged in the installation cavity 103, which can improve the cooling efficiency of the second chamber 102 and shorten the cooling time of the second chamber 102 to solve the problem of long cooling time and low cooling efficiency in the temperature zone storage area located relatively farther away from the evaporator 200.

[0099] The housing 100 provided in the embodiment of the present application has a first air duct cavity 400 , the first air duct cavity 400 is communicated with the first air inlet 1011 , and the evaporator 200 is located in the first air duct cavity 400 .

[0100] It can be understood that the provision of the first air duct cavity 400 can reduce the movement of the cold energy generated by the evaporator 200 toward the cabinet 100 or the external environment, thereby keeping the evaporator 200 cold; the first air duct cavity 400 is connected to the first air inlet 1011, so that the cold energy generated by the evaporator 200 can enter the first chamber 101 after passing through the first air inlet 1011, so as to drive the internal temperature of the first chamber 101 to decrease; thereby, the utilization rate of the cold energy of the evaporator 200 can be improved, so as to improve the performance of the refrigerator.

[0101] The box body 100 provided in the embodiment of the present application has a second air duct cavity; one end of the second air duct cavity is connected to the first chamber 101 through the first air outlet 1012, and the other end of the second air duct cavity is connected to the second chamber 102 through the second air inlet 1021.

[0102] It can be understood that the cold energy in the first chamber 101 is guided to the second air duct cavity after passing through the first air outlet 1012, and then passes through the second air duct cavity and through the second air inlet 1021 and then guided to the second chamber 102, so as to reduce the internal temperature of the second chamber 102. The provision of the second air duct cavity can improve the utilization rate of the cold energy in the first chamber 101, so as to reduce the energy consumption of the refrigerator, and can improve the performance of the refrigerator.

[0103] The connecting piece 300 provided in the embodiment of the present application has a connecting channel, and at least a portion of the connecting channel forms a second air duct cavity.

[0104] It can be understood that at least part of the connecting channel forms a second air duct cavity, which can reduce the difficulty of connecting between the first air outlet 1012 and the second air outlet, and has the advantage of simple processing; and can increase the cold flow diversion area between the first chamber 101 and the second chamber 102, so as to improve the cooling efficiency of the second chamber 102 and shorten the cooling time of the second chamber 102, thereby improving the performance of the refrigerator.

[0105] It should be noted that the connecting piece 300 has a variety of different configurations, and the configurations of the connecting piece 300 are described below in turn with examples.

[0106] In a feasible implementation, the connecting member 300 may be a conduit, one end of which is connected to the first air outlet 1012, and the other end of which is connected to the second air inlet 1021, and the conduit is used to guide the cold energy in the first chamber 101 to flow toward the second chamber 102. The inner wall of the conduit forms a connecting channel, and the cold energy in the first chamber 101 can be guided to the second chamber 102 after passing through the inner wall of the conduit.

[0107] It can be understood that the provision of the duct can reduce the difficulty of connecting the first air outlet 1012 and the second air outlet, and has the advantages of easy processing and installation.

[0108] In another feasible embodiment, the connecting piece 300 may be a guide plate, which is installed in the box body 100. The guide plate and the box body 100 form a connecting channel. The cold energy in the first chamber 101 can be guided to the second chamber 102 through the connecting channel formed by the guide plate and the box body 100.

[0109] It can be understood that the setting of the guide plate can increase the connection area between the first air outlet 1012 and the second air outlet, thereby increasing the guide area of ​​the cold air between the first chamber 101 and the second chamber 102, so as to improve the cooling efficiency of the second chamber 102 and shorten the cooling time of the second chamber 102, thereby improving the performance of the refrigerator.

[0110] It is understandable that there is no limitation on the specific configuration of the connecting piece 300 , and it can be selected according to actual use requirements, as long as the connecting piece 300 can guide the flow of cold air between the first chamber 101 and the second chamber 102 .

[0111] The refrigerator provided in the embodiment of the present application also includes: a fan 500, which is arranged in the first air duct cavity 400, with the air inlet end of the fan 500 arranged toward the evaporator 200, and the air outlet end of the fan 500 arranged toward the first air inlet 1011.

[0112] It can be understood that the fan 500 is used to speed up the circulation of cold air in the first air duct cavity 400 to shorten the time for the cold air in the first air duct cavity 400 to flow to the first chamber 101, thereby improving the cooling efficiency of the first chamber 101 and improving the performance of the refrigerator.

[0113] The embodiment of the present application provides that a plurality of second air inlets 1021 are provided.

[0114] It is understandable that, by providing a plurality of second air inlets 1021 , the air inlet area of ​​the second chamber 102 can be increased to improve the cooling efficiency of the second chamber 102 , thereby improving the performance of the refrigerator.

[0115] It should be noted that the plurality of second air inlets 1021 may be arranged in a variety of different ways. The following will illustrate the arrangement of the plurality of second air inlets 1021 in turn with examples.

[0116] In a feasible implementation manner, a plurality of second air inlets 1021 are arranged at intervals along the height direction of the box body 100 .

[0117] In another feasible implementation, a plurality of second air inlets 1021 are arranged at intervals along the height direction of the vertical box body 100 .

[0118] In addition, in another feasible implementation manner, the plurality of second air inlets 1021 are respectively arranged at intervals along the height direction of the box body 100 and perpendicular to the height direction of the box body 100 .

[0119] It is understandable that there is no restriction on the arrangement of the second air inlets 1021 , and the arrangement can be selected according to actual usage requirements, as long as the plurality of second air inlets 1021 are arranged at intervals.

[0120] The housing 100 provided in the embodiment of the present application has a third air duct cavity 600 ; one end of the third air duct cavity 600 is connected to the second chamber 102 .

[0121] It is understandable that the cold energy in the third air duct cavity 600 is used to be guided to the second air duct cavity to drive the internal temperature of the second cavity 102 to decrease.
