Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a freezer tank and a refrigerator. BACKGROUND

[0002] The freezer return air system of a refrigerator is an important component of the refrigerator refrigeration cycle system. It is mainly responsible for circulating the air in the freezer room to ensure temperature uniformity and refrigeration efficiency. Simply put, it is to make the cold air flow reasonably in the freezer room, just like the indoor air conditioner circulates cold and hot air through the fan.

[0003] During the refrigeration process in the freezer room, the air temperature around the evaporator will rapidly decrease. When the cold air sinks, it will be sucked back to the vicinity of the evaporator through the return air inlet. The return air inlet is designed to effectively collect the cooler air in the room. The air sucked back is cooled again by the evaporator and then blown back into the freezer room through the air outlet. This cycle continues, keeping the temperature in every corner of the freezer room relatively stable.

[0004] Currently, the freezer return air system in the refrigerator is designed in the freezer bubble layer, circulating the air in the refrigeration room back to the freezer room. Therefore, the conventional structure of the return air requires pre-buried plastic or foam material return air pipes in the bubble layer to form a cavity for return air. However, this structure occupies the volume of the bubble layer, reduces the insulation effect, and wastes labor during pre-installation. There is also a risk of material leakage at the air inlet position if the sealing is not good. CONTENT OF THE INVENTION

[0042] This application provides a refrigerator, which includes a cabinet, a refrigeration unit, and essential components such as a freezer compartment 1000 and a refrigerator compartment, as can be found in related technologies. In order to improve a series of problems caused by the return air duct 1004 occupying the foam layer, this application provides a design scheme that moves the return air duct 1004 out of the foam layer and instead designs the return air duct in the freezer compartment 1000.

[0043] See Figure 1 and Figure 2 As shown, this application provides a freezer liner 1000, the freezer liner 1000 having an interior chamber, i.e. Figure 2 As shown, the freezer liner 1000 contains a liner chamber with a front opening. This liner chamber forms the basis of the spatial structure of the freezer liner 1000, including the storage chamber 1001, the evaporation chamber 1002, the air supply duct 1003, and the return air duct 1004. For example... Figure 1 and Figure 2 As shown, the inner wall of the freezer liner 1000 is provided with an air supply port 1005 and an air return port 1006, both of which are configured to communicate with the inner chamber of the freezer.

[0044] This is the general structural design of the aforementioned freezer liner 1000. In this structural design, [the following is a description of the design process:] ... Figure 2It is known that the return air duct 1004 is integrated inside the freezer liner 1000, rather than being designed in the foam layer according to the traditional design. Based on this improved design, the transfer of the return air duct 1004 from the foam layer to the freezer liner 1000 is completely completed.

[0045] Continue reading Figure 2 As shown, in the internal design of the freezer liner 1000, the evaporator chamber 1002 is mainly configured to house the evaporator 2000. The evaporator 2000 occupies a portion of the space within the evaporator chamber 1002 and stably performs refrigeration work, cooling the surrounding air to form cold air. Simultaneously, the inlet of the air supply duct 1003 connects to the outlet of the evaporator chamber 1002, and the outlet of the air supply duct 1003 connects to the storage chamber 1001. The air supply duct 1003 can deliver a portion of the cold air to the storage chamber 1001 of the freezer liner 1000 to cool the storage chamber 1001.

[0046] Furthermore, the air outlet 1005 is connected to the air supply channel 1003, and the air supply channel 1003 is also configured to deliver a portion of the cold air outward through the air outlet 1005. That is, the air outlet 1005 is configured to deliver air to the outside of the freezer liner 1000, so that the cold air generated by the evaporator 2000 is used to deliver cold air to the freezer liner through the air outlet 1005 to cool the freezer liner.

[0047] Since the return air duct 1004 is designed in the aforementioned freezer liner 1000, the return air inlet 1006 of the freezer liner 1000 can be configured to receive return air from outside the freezer liner 1000, that is, to receive return air from the refrigerator liner. The inlet of the return air duct 1004 is connected to the return air inlet 1006, and the outlet of the return air duct 1004 is connected to the inlet of the evaporation chamber 1002. Thus, based on the return air duct 1004 integrated in the aforementioned freezer liner 1000, the return air from the refrigerator liner is received back to the evaporation chamber 1002, thereby completing the air supply and return air circulation of the refrigerator liner.

[0048] Continue reading Figure 1 and Figure 2 As shown, the return air duct 1004 can be designed to be installed on the rear wall of the freezer compartment 1000. The location of the return air duct 1004 on the rear wall of the freezer compartment 1000 facilitates airflow circulation with the refrigerator compartment, without excessively occupying food storage space within the freezer compartment. Furthermore, a portion of the interior of the evaporator compartment 1002 can be designated as a refrigeration zone, configured to house the evaporator 2000, while other areas within the evaporator compartment 1002 are used to guide the flow of cold air.

[0049] For example, the distance between the cooling zone and the inlet of the evaporator chamber 1002 is less than the distance between the inlet and outlet of the evaporator chamber 1002. After the cold air is generated, it can travel a certain distance before being discharged from the outlet. The return air is at a higher temperature; when it is received by the evaporator chamber 1002, it can enter through the inlet and quickly reach the cooling zone where the evaporator 2000 is located for cooling. Furthermore, the supply air vent 1005 is positioned higher than the return air vent 1006 within the freezer compartment 1000. The return air is relatively warm, such as air returning from 5 degrees Celsius to -20 degrees Celsius, which may condense and easily freeze. Heating elements, such as heating tubes, can be installed near the evaporator to alleviate icing.

[0050] Regarding the design of the return air channel 1004 in the freezer liner 1000, those skilled in the art can implement it based on various design methods. For example, in one embodiment, a return air cover 1100 can be provided on the inner wall of the freezer liner 1000. When the return air cover 1100 covers the inner wall of the freezer liner 1000, the space enclosed between the inner side wall of the return air cover 1100 and the inner wall of the freezer liner 1000 can be configured to form the return air channel 1004. In one embodiment, see [reference needed]. Figure 3 As shown, the inner wall of the freezer liner 1000 can also be provided with an air duct groove 1200, and a return air cover 1100 is provided on the air duct groove 1200. The inner side wall of the return air cover 1100 and the air duct groove 1200 are configured to form a return air channel 1004.

[0051] In the above design, if the inner wall of the freezer liner 1000 has an air duct groove 1200, it may reduce the wall thickness of the freezer liner 1000 to a certain extent. Therefore, if... Figure 4 As shown, compared to Figure 3 The air duct groove 1200 shown is in a certain state. A structural reinforcement 1300 can also be installed in the air duct groove 1200. The purpose of the structural reinforcement 1300 is to enhance the structural strength of the freezer liner 1000 that is reduced due to the opening of the air duct groove 1200.

[0052] For example, in one embodiment, the structural reinforcement 1300 may be configured to use a return air base plate. According to the strength coordination requirements and the design structure of the air duct groove 1200, the return air base plate may be selected to be set in at least a portion of the inner wall of the air duct groove 1200. For example, the area where the opening of the air duct groove 1200 causes the thickness of the inner wall to be reduced may be provided with a return air base plate. When the degree of thickness reduction is large, the thickness of the return air base plate at this location may be adaptively increased. Those skilled in the art can construct a suitable structural reinforcement scheme according to actual needs, which is not limited here.

[0053] Furthermore, regardless of whether the inner wall of the freezer liner 1000 has an air duct groove 1200, in one embodiment, see [reference] Figure 5 As shown, the return air cover 1100 can be configured as a curved panel with a certain curvature design, so that the inner side wall of the return air cover 1100 has a cover plate recess 1101, and the space enclosed between the cover plate recess 1101 of the return air cover 1100 and the air duct groove 1200 forms the aforementioned return air channel 1004.

[0054] Therefore, there are various ways to integrate the return air channel 1004 into the freezer liner 1000. Those skilled in the art can choose to integrate the return air channel 1004 into the freezer liner 1000 in ways including but not limited to those mentioned above, so as to achieve the technical purpose of transferring the return air channel 1004 from the foam layer to the freezer liner 1000. No limitation is made here.

[0055] Regarding the design of the dimensions of the return air duct 1004, this application also has certain design requirements. For example, in one embodiment, the return air duct 1004 is limited to having a duct width and a duct height. In this case, the duct width and duct height of the return air duct 1004 can be reflected according to a certain orientation of the freezer liner 1000. For example, the duct height can be the distance from the rear wall of the liner, thereby leading to the corresponding duct width. Those skilled in the art can limit the duct width and duct height of the return air duct 1004 according to a suitable spatial orientation.

[0056] The purpose of defining the return air duct 1004 with a duct width and a duct height is to limit the approximate variation of the return air duct 1004 based on the duct width and duct height of the return air duct 1004. For example, from the duct inlet of the return air duct 1004 to the duct outlet of the return air duct 1004, the duct width of at least a portion of the duct section or the duct width of all the duct sections of the return air duct 1004 can be designed to gradually increase, and the duct height of at least a portion of the duct section or the duct height of all the duct sections of the return air duct 1004 can be designed to gradually decrease.

[0057] like Figure 2 As shown, this can be roughly formed in the return air duct 1004 as a region that is more convex near the duct entrance and gradually flattens towards the duct exit. When the return air enters from the duct entrance of the return air duct 1004, it can be smoothly received based on the more convex spatial structure. When the return air flows towards the duct exit in the return air duct 1004, it can gradually slow down based on the simple spatial structure until it reaches the evaporator 2000.

[0058] However, the cross-sectional area of ​​the return air duct 1004 needs to remain constant throughout the entire return air duct 1004. For example, in one embodiment, the cross-sectional area of ​​the return air duct 1004 is between 800 square millimeters and 1200 square millimeters, and the specific cross-sectional area of ​​the return air duct 1004 can be selected as 800 square millimeters, 900 square millimeters, 1000 square millimeters, 1100 square millimeters, 1200 square millimeters, etc. Moreover, the width and height of the return air duct 1004 are both smaller than the width and height of the evaporation chamber 1002, making the internal space dimension of the return air duct 1004 smaller than the three-dimensional dimension of the evaporator 2000.

[0059] Regarding the construction method of the aforementioned storage compartment 1001, evaporation chamber 1002, air supply duct 1003, and other spaces within the refrigerator chamber, reference can be made to the designs in related technical solutions. In this application, for example, in one embodiment, the refrigerator chamber 1000 may be equipped with a compartment partition 1400 and an air duct cover 1500, such as... Figure 2 As shown, the partition 1400 and return air cover 1100 are configured to separate the evaporation chamber 1002, while the partition 1400 and duct cover 1500 are configured to separate the air supply duct 1003. Based on the arrangement of the partition 1400, duct cover 1500, and return air cover 1100 within the inner chamber, the inner chamber can be divided into spatial structures with different functions, such as a storage chamber 1001, an evaporation chamber 1002, an air supply duct 1003, and a return air duct 1004. Those skilled in the art can also construct these spaces in other ways, which are not limited here.

[0060] Continue reading Figure 5 and Figure 6 As shown, the return air cover 1100 is assembled to the inner wall of the freezer liner 1000 based on the snap-fit ​​assembly 1600. For example, the snap-fit ​​assembly 1600 has several snap-fit ​​parts, which are distributed at several different positions on the return air cover 1100. For example, several snap-fit ​​parts are provided along the edge of the return air cover 1100. The return air cover 1100 forms a snap-fit ​​assembly with the inner wall of the freezer liner 1000 by means of the snap-fit ​​ability of the snap-fit ​​parts. At the same time, the return air cover 1100 can also be optionally assembled to the inner wall of the freezer liner 1000 based on the threaded assembly 1700. For example, the threaded assembly 1700 has several threaded parts, which are distributed at several different positions on the return air cover 1100. The return air cover 1100 forms a threaded connection with the inner wall of the freezer liner 1000 by means of the threaded assembly ability of the threaded parts.

[0061] Continue reading Figure 2 and Figure 6As shown, the outer wall of the return air cover 1100 can face the evaporation chamber 1002. In this assembled state, the outer wall of the return air cover 1100 can be used to install the mounting assembly 1800. The evaporator 2000 is installed using the mounting assembly 1800, thus forming a certain degree of relative assembly between the evaporator 2000 and the return air cover 1100 when the evaporator 2000 is installed in the evaporation chamber 1002. The mounting assembly 1800 can achieve the installation function using various methods such as snap-fit, threaded connection, and adhesive bonding; no limitation is made here.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
