Description

Technical Field

[0001] The present application belongs to the technical field of refrigerators, and in particular relates to a refrigerator. Background Art

[0002] Refrigerators are usually divided into single-system refrigerators and dual-system refrigerators according to the number of refrigeration systems. The refrigerator and freezer compartments of a single-system refrigerator share a refrigeration system, so there is temperature crossover between the refrigerator and freezer compartments, which leads to odor transfer. The dual-system refrigerator has two independent refrigeration systems, which can be used for cooling the refrigerator and freezer compartments respectively. Therefore, the refrigerator and freezer compartments can be cooled separately, effectively preventing odor transfer.

[0003] However, since dual-system refrigerators include two refrigeration systems, their cost is relatively high and they are not suitable for low-priced refrigerators. Therefore, a low-cost refrigerator that does not carry over odors is in urgent need of development. Utility Model Content

[0048] The refrigerator provided in the embodiment of this application is Figures 1 to 5 , including a refrigeration compartment 8 and a freezer compartment 9, and also includes a refrigeration duct 1, a freezing duct 2, a freezing duct 2, a refrigeration fan 3, a freezing fan 4, and an evaporator 5. The refrigeration duct 1 is connected to the refrigeration compartment 8; the freezing duct 2 is connected to the freezer compartment 9, and the freezing duct 2 and the refrigeration duct 1 are separated. The refrigeration fan 3 is arranged in the refrigeration duct 1; the freezing fan 4 is arranged in the freezing duct 2. The evaporator 5 includes a first evaporation body 51 and a second evaporation body 52 connected in series. The first evaporation body 51 is arranged in the refrigeration duct 1, and the second evaporation body 52 is arranged in the freezing duct 2. The length of the second evaporation body 52 is greater than that of the first evaporation body 51.

[0049] The refrigerator provided in the embodiment of the present application realizes independent refrigeration of the refrigeration compartment 8 and the freezer compartment 9 by respectively exchanging heat with the first evaporation body 51 and the second evaporation body 52 connected in series, thereby preventing odor contamination. At the same time, there is only one evaporator 5, which only requires one compressor, rather than two, thus saving manufacturing costs. The length of the second evaporation body 52 is greater than that of the first evaporation body 51, making the second evaporation body 52 for heat exchange with the freezer compartment 9 longer, thereby meeting the larger heat exchange capacity of the freezer compartment 9 and achieving a reasonable distribution of the heat exchange area of ​​the two parts of the series of one evaporator 5. Compared with a single-system refrigerator, the refrigerator provided in the embodiment of the present application can realize independent refrigeration of the refrigerator and freezer, avoiding odor contamination. Compared with a dual-system refrigerator, the refrigerator provided in the embodiment of the present application is less expensive.

[0050] The lengths of the first evaporation body 51 and the second evaporation body 52 are not further limited here, and they only need to meet the heat exchange requirements of the refrigeration compartment 8 and the freezing compartment 9 .

[0051] Optionally, the refrigeration air duct 1 includes a first channel 11 and a second channel 12 that are connected, the first channel 11 is located on one side of the freezer compartment 9, the second channel 12 is located on one side of the refrigeration compartment 8, and the first evaporation body 51 is arranged in the first channel 11; the freezing air duct 2 is located on one side of the freezer compartment 9 and is spaced apart from the first channel 11.

[0052] By placing the two parts of the refrigeration air duct 1 opposite to the refrigeration compartment 8 and the freezer compartment 9 respectively, the first evaporation body 51 and the second evaporation body 52 can be arranged side by side on one side of the freezer compartment 9 to ensure a larger heat exchange capacity of the freezer compartment 9, and the length of the communication channel between the second evaporation body 52 and the freezer compartment 9 is shorter, ensuring less cold loss and improving the heat exchange efficiency between the second evaporation body 52 and the freezer compartment 9.

[0053] The positional relationship between the refrigeration compartment 8 and the freezing compartment 9 is not further limited here. In some examples, please refer to Figure 4 , Figure 4 This is a structural diagram of the refrigeration compartment 8 and the freezer compartment 9 of the refrigerator provided in an embodiment of the present application. The refrigeration compartment 8 is located above the freezer compartment 9. In other examples, the refrigeration compartment 8 is adjacent to the freezer compartment 9 on the left and right.

[0054] Optionally, the refrigerator provided in the embodiment of the present application includes a refrigerator and a partition 6. The partition 6 is disposed within the refrigerator. One side of the partition 6 is separated into a refrigerated compartment 8 and a frozen compartment 9. The other side of the partition 6 includes a first space opposite the frozen compartment 9 and a second space opposite the refrigerated compartment 8. The second space is provided with a second passage 12. The first space is provided with a barrier 61 and first and second evaporating bodies 51 and 52. The barrier 61 is sandwiched between the first and second evaporating bodies 51 and 52, and divides the first space into the freezing air duct 2 and the first passage 11.

[0055] That is, the barrier 61 separates the first space into the freezing air duct 2 and the first channel 11, making the freezing air duct 2 and the first channel 11 independent of each other, thereby preventing cold air from leaking between the freezing air duct 2 and the first channel 11, thereby affecting the cooling effect of the refrigeration compartment 8 or the freezer compartment 9. The shape of the barrier 61 is not further limited herein.

[0056] Optionally, a sealing rib 62 is further provided in the first space, one end of the sealing rib 62 is connected to the blocking member 61, and the other end and the blocking member 61 are provided with a connecting port 13, the sealing rib 62 and the blocking member 61 are jointly arranged around the outer periphery of the first evaporation body 51 to form a first channel 11, and the connecting port 13 connects the first channel 11 and the second channel 12.

[0057] That is, the first evaporator body 51 is enclosed by the blocking member 61 and the sealing rib 62, further limiting the capacity of the first channel 11 so that the first channel 11 is arranged to fit the first evaporator body 51 as closely as possible, thereby avoiding excessive loss of cold energy in the refrigeration duct 1, and increasing the percentage of cold energy entering the refrigeration compartment 8 as much as possible, thereby reducing cold energy loss.

[0058] Optionally, a refrigerated air inlet is penetrated by the partition 6, and the refrigerated air inlet connects the refrigerated air duct 1 and the refrigerated compartment 8; a guide plate 7 is provided in the refrigerated air duct 1, and one end of the guide plate 7 close to the first evaporating body 51 is connected to the partition 6, and the other end extends toward the refrigerated air inlet and is clamped with the partition 6 to form an installation cavity, and the refrigerated fan 3 is installed in the installation cavity, and one end of the guide plate 7 close to the refrigerated air inlet is clamped with the partition 6 to form a guide outlet 72, and the guide plate 7 is also penetrated by a guide inlet 71 opposite to the rotating shaft of the refrigerated fan 3.

[0059] By setting a guide plate 7 in the refrigerated air duct 1, the airflow in the refrigerated air duct 1 is guided so that the airflow is accelerated by the turbulence at the refrigerated fan 3 and then flows to the refrigerated air inlet, thereby increasing the airflow speed in the refrigerated air duct 1 and avoiding the airflow from staying in the refrigerated air duct 1 for a long time, thereby increasing the cooling loss.

[0060] The position of the guide plate 7 in the refrigeration air duct 1 is not further limited here. In some examples, please refer to Figure 3 , Figure 3 This is a first view of a second structural schematic diagram of the guide plate 7 of the refrigerator provided in an embodiment of the present application. The guide plate 7 can be arranged in the first channel 11. In other examples, see Figures 1 to 2 , Figure 1 This is a first view of a first structural schematic diagram of the guide plate 7 of the refrigerator provided in an embodiment of the present application. Figure 2 This is a second view of the first structural schematic diagram of the guide plate 7 of the refrigerator provided in an embodiment of the present application. The guide plate 7 can be set in the second channel 12.

[0061] Optionally, the width of the deflector 7, perpendicular to the direction of gas flow, is the same as the width of the corresponding portion of the refrigeration duct 1. That is, both sides of the deflector 7 abut the sidewalls of the refrigeration duct 1, allowing airflow to flow only through the deflector inlet 71 on the deflector 7 and out through the deflector outlet 72, thereby maximizing the airflow acceleration effect within the refrigeration duct 1. The shape of the deflector 7 is not further specified herein; it can simply match the corresponding sidewalls of the refrigeration duct.

[0062] Optionally, the guide plate 7 includes a first guide portion 73 , which is located at an end of the guide inlet 71 close to the first evaporation body 51 , and the distance between the first guide portion 73 and the partition plate 6 gradually increases toward the end away from the first evaporation body 51 .

[0063] By providing the first guide portion 73 , the airflow flowing from the first evaporation body 51 to the guide inlet 71 is gradually lifted by the first guide portion 73 during the flow process, thereby increasing the air intake speed at the guide inlet 71 .

[0064] Optionally, the guide plate 7 further includes a second guide portion 74, which is located at one end of the guide inlet 71 close to the refrigerated air inlet, and the distance between the second guide portion 74 and the partition 6 gradually increases toward the end close to the refrigerated air inlet.

[0065] By providing the second guide portion 74, the gas at the guide outlet 72 is guided, the outlet cross-section of the guide outlet 72 is increased, and the speed of the air flow toward the refrigerated air inlet is increased.

[0066] Optionally, an installation space is provided in the partition 6, and the partition 6 is further provided with a freezing air inlet connecting the installation space and the freezing compartment 9, and a conducting port connecting the installation space and the freezing air duct 2, and the freezing fan 4 is arranged in the installation space.

[0067] That is, the refrigeration fan 4 is directly arranged in the partition 6, which saves the installation space in the first space and reduces the overall volume of the refrigerator.

[0068] Optionally, a plurality of refrigerated air inlets are provided and spaced apart on the partition 6. The number of refrigerated air inlets is not further limited herein and can be further selected as needed. By increasing the number of refrigerated air inlets, the heat exchange efficiency between the freezing chamber 9 and the second evaporating body 52 is improved, thereby increasing the cooling rate of the freezing chamber 9.

[0069] In this structure, when the refrigerating compartment 8 needs to be cooled, the refrigerating fan 3 can be turned on, and when the freezing compartment 9 needs to be cooled, the freezing fan 4 can be turned on, thereby achieving relatively independent cooling of the refrigerating compartment 8 and the freezing compartment 9.

[0070] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0071] The above is a detailed introduction to the refrigerator provided in the embodiment of the present application.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present application.
