Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a refrigerator. Background Technology

[0002] Traditional refrigerators typically have multiple compartments, each with its own temperature zone. When operating, cold air is directly delivered to the compartment and then enters the drawers inside to cool the items stored there. In this case, the cooling effect is relatively poor.

[0003] The above statements are for the purpose of providing background information in relation to this application only, and do not necessarily constitute prior art. Utility Model Content

[0004] One of the technical problems this application aims to solve is: improving the cooling effect of refrigerators.

[0005] To address the aforementioned technical problems, this application provides a refrigerator comprising:

[0006] The container has a first compartment inside;

[0007] The first drawer, located in the first room, can move back and forth between a pulled-out position and a pushed-in position. The first drawer is equipped with an air inlet.

[0008] An air duct is installed inside the housing and has an air outlet. The air outlet is used to cooperate with the air inlet and, when the first drawer is in the pushed-in position, it is connected with the air inlet of the first drawer so that cold air flows to the first drawer through the connected air outlet and air inlet.

[0009] In some embodiments, the air outlet and the air inlet are detachably connected; and / or, the air duct is disposed on the rear side of the first drawer.

[0014] In some embodiments, cooling channels are provided in the left and right side walls of the first drawer, and the cooling channels in the left and right side walls of the first drawer are respectively connected to different air inlets on the first drawer, so that cold air flows into the cooling channels in the left and right side walls of the first drawer.

[0015] In some embodiments, the first drawer with a cooling channel inside the cavity wall is a flash-freezing drawer; or, the first drawer with the air inlet connected to the storage cavity is a quick-freezing drawer.

[0016] In some embodiments, the refrigerator includes a plurality of first drawers arranged side by side in a first compartment, each first drawer having an air inlet, and an air duct having an air outlet corresponding to the air inlet of each first drawer.

[0017] In some embodiments, a plurality of first drawers are arranged side by side in a left-right direction in a first compartment; and / or, the plurality of first drawers include at least one of a flash-freezing drawer and a quick-freezing drawer.

[0018] In some embodiments, the refrigerator further includes a drawer drawer disposed in a first compartment, with a plurality of first drawers arranged side by side in the drawer drawer drawer and moving together with the drawer drawer drawer between a pull-out position and a push-in position.

[0019] In some embodiments, the refrigerator body is further provided with a second compartment. The second compartment and the first compartment are arranged in a vertical direction. The air duct component also has an air supply port. The refrigerator also includes an air guide component, which is disposed above the second compartment and has an air guide duct inside. The air guide duct includes a first air duct and a second air duct. The first air duct and the second air duct are arranged at an angle to each other and both connect to the air supply port and the second compartment to guide the cold air flowing into the air guide component through the air supply port to flow into the second compartment from different positions.

[0020] In some embodiments, the air duct is configured as follows:

[0021] The first air duct extends in the left-right direction;

[0023] The first air duct is provided with a first partition, which divides the first air duct in the width direction;

[0024] The second air duct is equipped with a second baffle, which divides the second air duct in the width direction.

[0025] In some embodiments, the air duct further includes a third air duct, which is connected to the opposite ends of the first air duct at an angle to the first air duct and is connected to the air supply port through the first air duct.

[0026] In some embodiments, the third air duct is configured as at least one of the following:

[0027] The third air duct and the second air duct are parallel to each other;

[0028] The third and second air ducts bend to the same side relative to the first air duct;

[0029] The third air duct is equipped with a third partition, which divides the third air duct in the width direction.

[0030] In some embodiments, the second compartment is a variable temperature compartment; and / or, the second compartment is located below the first compartment.

[0065] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0066] In the description of this application, the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0067] In the description of this application, it should be understood that the directional terms "inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself. Furthermore, the directional terms such as "front," "back," "up," "down," "left," and "right," "horizontal," "vertical," "horizontal," and "top" and "bottom" indicate directions or positional relationships that are generally based on the normal placement of the refrigerator. Specifically, the direction parallel to the direction of gravity is defined as the vertical direction Z, with directions opposite to and the same as the direction of gravity defined as "up" and "down," respectively; the relative arrangement of the refrigerator door and body is defined as the front-back direction X, with the side containing the door and body defined as "front" and "back," respectively; the direction perpendicular to both the front-back direction X and the vertical direction Z is defined as the left-right direction, with left and right respectively when facing forward. This definition of "front," "back," "up," "down," "left," and "right" is consistent with... Figure 1 The directions "front, back, up, down, left, right" shown are consistent.

[0068] In this application, "multiple" means at least two, that is, two, three or more.

[0069] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0070] To make it easier to understand, let's first combine... Figure 1 The structure of the refrigerator is explained.

[0071] See Figure 1 A refrigerator 100 typically includes a cabinet 1, a door 91, and drawers 17.

[0072] The cabinet 1 contains a compartment 10. The compartment 10 is used to house the drawer 17. Typically, the cabinet 1 contains multiple compartments 10. These compartments 10 are arranged along the vertical (Z) and / or horizontal (Y) directions. See, for example... Figure 1In some embodiments, the housing 1 has multiple compartments 10 arranged along the vertical direction Z, including a first compartment 11, a second compartment 12, and a third compartment 13, which are sequentially distributed from top to bottom. Specifically, in some embodiments, the housing 1 is divided into upper and lower sections, with the upper section being a refrigeration section and the lower section being a freezing section. Both the refrigeration and freezing sections have multiple compartments 10 arranged along the vertical direction Z. The compartments 10 of the freezing section include a first compartment 11, a third compartment 13, and a second compartment 12 arranged sequentially from top to bottom. The first compartment 11, the third compartment 13, and the second compartment 12 are respectively used as a freezing compartment 14, a deep-freezing compartment 16, and a variable-temperature compartment 15, such that the freezing compartment 14, the deep-freezing compartment 16, and the variable-temperature compartment 15 are arranged side by side along the vertical direction Z and sequentially arranged from top to bottom, becoming the upper compartment, the middle compartment, and the lower compartment of the freezing section, respectively.

[0073] The door 91 is closably connected to the cabinet 1 and is used to control the opening and closing of at least one compartment 10 of the refrigerator 100. For example, see... Figure 1 In some embodiments, the upper refrigeration compartment has two doors 91, which are used to control the opening and closing of the compartment 10 of the refrigeration compartment; at the same time, the lower freezer compartment has one door 91, which is used to control the opening and closing of the compartment 10 of the freezer compartment. Of course, the configuration of the doors 91 is not limited to this, and can be configured according to actual needs.

[0074] Drawer 17 is located in compartment 10 and is used to store items (such as food items like fruits, vegetables, meat, and eggs, as well as other items that require refrigeration or freezing, such as ice packs and ice blocks). Typically, drawer 17 has a storage cavity 20. The storage cavity 20 is formed by cavity walls 263 (see...). Figure 4 An enclosed area used for storing items.

[0075] In addition, refrigerator 100 also has a cooling system 6 (see Figure 2 The cooling system 6 includes a fan 80 (see...). Figure 8 ) and evaporator 8 (see Figure 6 The evaporator 8, along with the compressor and condenser, is located in the refrigerant circulation loop to cool the gas and produce cold air. The fan 80 provides the driving force for the gas flow, propelling it through the evaporator 8 to become cold air, and further driving the cold air from the evaporator 8 to the compartment 10 to cool and preserve the items in the drawer 17 within the compartment 10, extending their storage time and maintaining their quality for a longer period.

[0076] Different compartments 10 may share a fan 80 and an evaporator, or they may use different fans 80 and evaporators. For example, in some embodiments, in the first compartment 11, the third compartment 13, and the second compartment 12 distributed from top to bottom, the first compartment 11 and the third compartment 13 share a set of fans 80 and evaporators 8, while the second compartment 12 uses a separate set of fans 80 and evaporators 8.

[0077] In a traditional refrigerator 100, the cooling system typically supplies air directly to each compartment 10. The air then enters the drawers 17 within each compartment 10 to cool the items stored in the drawers 17. In this case, because the cold air needs to enter the compartment 10 first and then the drawers 17 within the compartment 10, the cooling capacity needs to be transferred from the compartment 10 to the drawers 17. The cooling capacity transfer path is relatively long, resulting in significant cooling capacity loss and therefore poor cooling performance.

[0078] It is evident that traditional refrigerators, which use a design that directly supplies air to each room, suffer from poor cooling performance.

[0079] In order to improve the cooling effect of the refrigerator, this application improves the structure of the refrigerator and provides a refrigerator.

[0080] Figures 1-17 The structure of the refrigerator in this application is illustrated by way of example.

[0081] See Figures 1-17 In this application, the refrigerator 100 includes a cabinet 1, a first drawer 21, and an air duct component 7. The cabinet 1 contains a first compartment 11. The first drawer 21 is disposed within the first compartment 11 and is movable in the front-rear direction X between a pulled-out position and a pushed-in position. The first drawer 21 has an air inlet 22. The air duct component 7 is disposed within the cabinet 1 and has an air outlet 741. The air outlet 741 engages with the air inlet 22 and, when the first drawer 21 is in the pushed-in position, connects with the air inlet 22 of the first drawer 21, so that cold air flows to the first drawer 21 through the connected air outlet 741 and air inlet 22.

[0082] Since the air duct component 7 and the first drawer 21 located in the first compartment 11 are respectively provided with an air outlet 741 and an air inlet 22, the air outlet 741 and the air inlet 22 can be connected to each other when the first drawer 21 is in the pushed position. Therefore, when the first drawer 21 needs to be cooled, the cold air does not need to flow into the first compartment 11 first and then into the first drawer 21. Instead, it can flow directly from the air outlet 741 on the air duct component 7 through the air inlet 22 on the first drawer 21 to the first drawer 21. In this way, the process of cold energy transfer from the first compartment 11 to the first drawer 21 can be omitted, the cold energy transfer path can be shortened, and the cold energy loss can be reduced. Therefore, the cooling efficiency of the first drawer 21 can be effectively improved, the cooling effect of the first drawer 21 can be improved, and the cooling effect of the refrigerator 100 can be enhanced.

[0083] Moreover, since the cold energy does not need to be transferred from the first compartment 11 to the first drawer 21, the cooling effect of the first drawer 21 is not affected by the uniformity of the cold energy distribution in the first compartment 11. The first drawer 21 is easier to cool evenly. From this perspective, it is also beneficial to improve the cooling effect of the first drawer 21 and enhance the cooling effect of the refrigerator 100.

[0084] As can be seen, by setting an air outlet 741 and an air inlet 22 on the air duct 7 and the first drawer 21 located in the first compartment 11 respectively, and constructing the air outlet 741 and the air inlet 22 to engage with each other when the first drawer 21 is in the pushed position, direct air supply from the air duct 7 to the first drawer 21 can be achieved, which can reduce cold loss and improve the uniformity of cooling. Therefore, the cooling effect of the refrigerator 100 can be effectively improved.

[0085] Furthermore, by providing an air outlet 741 and an air inlet 22 on the air duct 7 and the first drawer 21 located in the first compartment 11 respectively, and by configuring the air outlet 741 and the air inlet 22 to engage with each other when the first drawer 21 is in the pushed-in position, direct air supply from the air duct 7 to the first drawer 21 can be achieved. This also facilitates the setting of multiple temperature zones in the first compartment 11, effectively meeting various preservation needs while occupying a small space.

[0086] When the refrigerator uses a direct airflow method into the compartments, the overall temperature of each compartment is roughly the same, forming a single temperature zone. To create multiple temperature zones, multiple compartments would be needed, making it difficult to achieve a multi-temperature zone design within the same compartment. Furthermore, regardless of whether the compartments are arranged vertically or horizontally, partition walls are required to separate them, thus occupying more space. This can lead to a larger overall refrigerator size, making it less compact. It can also limit the number of compartments, drawers, or other components that can be accommodated within the same space, restricting the number of temperature zones or affecting the functionality of certain features.

[0087] This application employs a method of directly supplying air to the drawers within a compartment without bypassing the intercom. In this case, only multiple drawers need to be installed in the same compartment, with corresponding air outlets 741 and air inlets 22 for each drawer. Direct airflow to these drawers allows them to reach different preset cooling temperatures, conveniently creating different temperature zones within the same compartment. In other words, multi-temperature zone settings within the same compartment can be easily achieved. Because of this multi-temperature zone setting, no additional partitions or other separations are needed between drawers within the same compartment, allowing for a more compact arrangement and thus less space usage. From one perspective, this reduces the space occupied by multiple temperature zones, decreasing the overall size of the refrigerator 100 and making it more compact. From another perspective, it optimizes the spatial layout, enabling more compartments and drawers (e.g., ...) to be arranged within the same size space. Figure 1 The ice drawer 29 in the refrigerator can be used to increase the number of temperature zones to meet more diverse cooling needs, or additional components can be added to enrich the refrigerator's functions.

[0088] For example, see Figure 1 and Figure 2 In some embodiments, the refrigerator 100 includes a plurality of first drawers 21 arranged side-by-side in a first compartment 11, and each first drawer 21 is provided with an air inlet 22. Simultaneously, the air duct component 7 has an air outlet 741 corresponding one-to-one with the air inlet 22 of each first drawer 21. Thus, the first compartment 11 contains a plurality of first drawers 21, and each first drawer 21 can directly obtain cold air from the air duct component 7 without passing through the first compartment 11, achieving different preset cooling temperatures and forming multiple temperature zones. This allows for a multi-temperature zone design within a relatively small space, meeting various storage needs. In particular, in this case, each first drawer 21 of the first compartment 11 can directly obtain cold air from the air duct component 7, resulting in higher cooling efficiency, stronger cooling uniformity, and better cooling effect. Therefore, not only can a multi-temperature zone design be achieved within a relatively small space to meet various storage needs, but also a multi-temperature zone design with good cooling effect in each temperature zone can be achieved within a relatively small space, better meeting various storage requirements.

[0089] The arrangement of the multiple first drawers 21 within the first compartment 11 is not limited in any particular direction. See, for example... Figure 1 Multiple first drawers 21 are arranged side by side along the left-right direction Y in the first compartment 11. In this case, the layout of multiple first drawers 21 is more reasonable, easier to push and pull, and also easier to arrange the air outlets 741 and other air outlets corresponding to each first drawer 21 on the air duct component 7, thereby improving the rationality of the air outlet layout on the air duct component 7 and realizing a more reasonable use of the space of the air duct component 7.

[0090] See Figure 1 and Figure 2 In the case where a plurality of first drawers 21 are provided in the first compartment 11, the plurality of first drawers 21 may include at least one of a flash-freezing drawer 26 and a quick-freezing drawer 27.

[0091] Flash freezing and quick freezing can meet different freezing needs. Generally, the preset cooling temperature for flash freezing (also known as the flash freezing temperature) is higher than that for quick freezing (also known as the quick freezing temperature). For example, in some embodiments, the flash freezing temperature is -5°C, while the quick freezing temperature is -18°C. Generally, flash freezing is used to preserve meat, while quick freezing is used to preserve ice packs, etc.

[0092] Since the flash-freezing drawer 26 and the quick-freezing drawer 27 can form a flash-freezing temperature zone and a quick-freezing temperature zone respectively, by setting the plurality of first drawers 21 in the first compartment 11 as at least one of the flash-freezing drawer 26 and the quick-freezing drawer 27, the first compartment 11 can be provided with at least one of the flash-freezing temperature zone and the quick-freezing temperature zone, effectively meeting at least one of the flash-freezing and quick-freezing requirements while occupying less space.

[0093] In particular, when multiple first drawers 21 within the first compartment 11 simultaneously include both a flash-freezing drawer 26 and a quick-freezing drawer 27, the first compartment 11 can simultaneously provide both a flash-freezing temperature zone and a quick-freezing temperature zone. This not only effectively meets the flash-freezing and quick-freezing requirements within the single first compartment 11, but also facilitates the sharing of a single fan 80 and an evaporator 8 between flash-freezing and quick-freezing (see...). Figure 8 The first fan 81 and the first evaporator 83 shown are particularly important. Both flash freezing and quick freezing are forms of refrigeration, and the difference in their preset cooling temperatures is quite suitable. Integrating them into the same compartment allows for convenient cooling of both using the same fan 80 and the same evaporator 8, effectively meeting their different preset cooling temperature requirements. For example, when the flash freezing drawer 26 and the quick freezing drawer 27 are pushed to the advanced position, the shared fan 80 and evaporator 8 can be started, and cooling can be directly supplied to the flash freezing drawer 26 and the quick freezing drawer 27 through the air duct 7. As the cooling process continues, the flash freezing temperature is reached first, and the cooling supply to the flash freezing drawer 26 can be stopped by closing the damper 92, as mentioned below. However, the shared fan 80 and evaporator 8 continue to work, supplying cooling to the quick freezing drawer 27, so that the subsequent quick freezing drawer 27 reaches the quick freezing temperature.

[0094] Furthermore, when multiple first drawers 21 are provided in the first compartment 11, the multiple first drawers 21 can be pushed and pulled out independently, or they can be pushed and pulled out together. For example, see Figure 1 and Figure 2In some embodiments, the refrigerator 100 further includes a drawer 23 disposed in the first compartment 11, with multiple first drawers 21 arranged side-by-side in the drawer 23 and moving together with the drawer 23 between a pulled-out position and a pushed-in position. In this case, the multiple first drawers 21 can move back and forth together with the drawer 23, allowing for synchronized pushing and pulling of the multiple first drawers 21 simply by pushing and pulling the drawer 23, which is simple, convenient, and saves time and effort.

[0095] In the foregoing embodiments, the connection between the air outlet 741 and the air inlet 22 can be either an inseparable connection or a separable connection.

[0096] When the air outlet 741 and the air inlet 22 are inseparably connected, the air outlet 741 and the air inlet 22 are always connected. They are connected not only when the first drawer 21 is in the pushed-in position, but also when the first drawer 21 is in the pulled-out position.

[0097] When the air outlet 741 and the air inlet 22 are detachably connected, a movable rather than fixed air duct structure is formed between the air outlet 741 and the air inlet 22. In this case, the air outlet 741 and the air inlet 22 are not necessarily always connected, but can be connected only when needed and separated when not needed. Therefore, it is more flexible and easier to meet more diverse needs. For example, the air outlet 741 and the air inlet 22 can be designed to separate from each other when the first drawer 21 is pulled outward. This allows the first drawer 21 to move outward without being restricted by the air outlet 741, making it more flexible and easier to pull out, thus enhancing its usability and improving the user experience. On the other hand, the air outlet 741 and the air inlet 22 can separate from each other when the first drawer 21 is in the pulled-out position, enabling the first drawer 21 to be detachable. This allows the first drawer 21 to be easily removed for cleaning or replacement, preventing damage from dirt and grime that could affect the cooling effect and user experience. Therefore, this further improves the cooling effect and enhances the user experience.

[0098] As can be seen, when the connection between the air outlet 741 and the air inlet 22 is a separable connection, a movable air duct structure (or movable air duct structure) can be formed that connects or separates as the first drawer 21 is pushed and pulled. This movable air duct structure makes it easier to move the first drawer 21, and in particular, it makes it easier to remove the first drawer 21 from the cabinet 1 for cleaning or replacement. This is beneficial to further improve the cooling effect and enhance the user experience.

[0099] The separable connection between the air outlet 741 and the air inlet 22 can be achieved in various ways. For example, the air outlet 741 and the air inlet 22 can be butt-joined or plug-in joined. It can be understood that butt-joining means that the end faces of two structures are facing each other and in contact, without any other constraints between them; while plug-in means that two structures are nested within each other, that is, one is nested outside the other, or one is inserted into the other.

[0100] Since both docking and plugging are detachable connection methods, the air outlet 741 and air inlet 22 can be easily separated when docked or plugged together. Furthermore, when docking, the air outlet 741 and air inlet 22 only have end-face contact without other constraints, making separation easier. When plugging, one inserts into the other, creating mutual constraint and resulting in a stronger, more airtight connection. This reduces cold air leakage, further minimizing cooling loss, improving cooling efficiency, and enhancing the cooling effect.

[0101] In addition, to reduce cold air leakage and cooling loss, please refer to... Figures 13-16 In some embodiments, the refrigerator 100 further includes a seal 89, which is disposed on at least one of the air outlet 741 and the air inlet 22 for sealing. Thus, the seal 89 can seal the air duct formed when the air outlet 741 and the air inlet 22 are joined, thereby reducing cold air leakage, reducing cold energy loss, improving cooling efficiency, and enhancing the cooling effect. In particular, when the air outlet 741 and the air inlet 22 are inserted together, the seal 89 can be pressed between the first drawer 21 and the air duct component 7, resulting in a better seal and further improving cooling efficiency and effect. In other words, the insertion of the air outlet 741 and the air inlet 22 further facilitates cooperation with the seal 89, improving the sealing effect, enhancing cooling efficiency, and improving the cooling effect.

[0102] Specifically, see Figure 16 In some embodiments, the seal 89 includes a sleeve 87 and a flange 88. The flange 88 is disposed at the end of the sleeve 87 and is compressed when the first drawer 21 is in the pushed-in position. Thus, when the first drawer 21 is pushed into place and reaches the pushed-in position, a seal is automatically formed by compressing the seal 89. In particular, the designed flange 88 can enhance the compression effect and achieve a tighter seal. Therefore, it is more conducive to reducing cold air leakage, reducing cold loss, improving refrigeration efficiency, and improving refrigeration effect.

[0103] In the foregoing embodiments, since the air duct 7 directly supplies cold air to the first drawer 21, the first drawer 21 can be further equipped with a drawer cover 28. The drawer cover 28 is disposed on the top of the first drawer 21 and is used to close the top opening of the first drawer 21. In this way, during the process of supplying cold air to the first drawer 21, the drawer cover 28 can close onto the first drawer 21 to prevent air leakage, thereby improving the cooling effect.

[0104] As a further improvement to the foregoing embodiments, see Figure 9 The refrigerator 100 also includes a damper 92, which controls whether the connected air outlet 741 and air inlet 22 are connected.

[0105] Based on the damper 92, when the first drawer 21 is in the pushed-in position, although the air outlet 741 and the air inlet 22 are connected, they are not necessarily connected. Instead, they are controlled by the damper 92 to open and close, and the damper 92 controls whether to send cold air to the first drawer 21. This allows for more convenient and accurate temperature control of the first drawer 21, ensuring it reaches and remains at the preset cooling temperature. This achieves a more suitable cooling effect, extends the preservation time of items inside the first drawer 21, and improves the preservation quality of the items. When the first drawer 21 is pushed to the advanced position, the damper 92 can be opened first, controlling the connection between the connected air outlet 741 and the air inlet 22 to deliver cooling to the first drawer 21, lowering its temperature and keeping the items inside cold and fresh. Once the temperature of the first drawer 21 reaches the preset cooling temperature, the damper 92 can be closed, cutting off the connection between the connected air outlet 741 and the air inlet 22, stopping the delivery of cooling to the first drawer 21, and ensuring it remains at the preset cooling temperature. This prevents the first drawer 21 from becoming too cold and affecting the preservation of the items.

[0106] Moreover, as mentioned earlier, the damper 92 also facilitates the installation of multiple first drawers 21 in the first chamber 11, especially when multiple first drawers 21 share the same evaporator 8. By controlling the dampers 92 of different first drawers 21 to close sequentially, different first drawers 21 can reach their respective preset cooling temperatures.

[0107] In addition, the damper 92 can also be closed before the first drawer 21 is pulled out or when the door 91 controlling the opening and closing of the first compartment 11 is opened, thus disconnecting the air supply vent 741 and the air inlet 22. This prevents air from being supplied to the first drawer 21 when it is pulled out or when the door 91 is opened. This reduces the adverse effects of airflow on pulling the first drawer 21, making it easier to pull the first drawer 21 out. It also prevents air leakage when the first drawer 21 is pulled out or air from being supplied when the door 91 is opened, thereby reducing the waste of cooling capacity and improving the energy efficiency of the refrigerator 100.

[0108] Before the first drawer 21 is pulled out or when the door 91 controlling the opening and closing of the first compartment 11 is opened, not only can the energy waste of the refrigerator 100 be reduced by controlling the damper 92 to close, thus improving the energy efficiency of the refrigerator 100, but also the energy waste of the refrigerator 100 can be reduced by controlling the fan 80 used to drive the airflow to the first drawer 21 to close, thus improving the energy efficiency of the refrigerator 100.

[0109] In some embodiments, before the first drawer 21 is pulled out or when the door 91 controlling the opening and closing of the first compartment 11 is opened, not only is the damper 92 corresponding to the first drawer 21 closed, but the fan 80 corresponding to the first drawer 21 is also turned off. This can save energy and electricity more effectively and improve the energy efficiency of the refrigerator 100.

[0110] In fact, not only can the corresponding fan 80 be shut down when the door 91 of the first compartment 11 is opened, but the corresponding fan 80 of other compartments 10 can also be shut down when the door 91 of other compartments 10 is opened, so as to save energy and electricity.

[0111] To easily determine whether the door 91 is open, see [link / reference]. Figure 1 In some embodiments, the refrigerator 100 includes a detection element 93 that detects whether the door 91 is open, and the fan 80 shuts off when the door 91 is detected to be open. Based on this, it is possible to determine more promptly and accurately whether the door 91 is open, and to control the fan 80 to shut off when the door 91 is open more promptly and accurately. This is more conducive to energy saving and improves the energy efficiency of the refrigerator 100. The detection element 93 can be, but is not limited to, a proximity switch or similar structure, as long as it can detect whether the door 91 is open.

[0112] In the foregoing embodiments, the air inlet 22 of the first drawer 21 may be connected to the storage cavity 20 or other parts of the first drawer 21 to circulate cold air to the storage cavity 20 or other parts of the first drawer 21.

[0113] When the air inlet 22 of the first drawer 21 is connected to the storage cavity 20 of the first drawer 21, cold air can flow through the air inlet 22 into the storage cavity 20 of the first drawer 21. At this time, the cold air flows directly into the storage cavity 20 of the first drawer 21, allowing it to directly contact the items inside, resulting in higher cooling efficiency and better cooling effect. This is especially suitable for items requiring lower temperatures and those that are not afraid of drying due to outer packaging. For example, see... Figure 5In some embodiments, the first drawer 21, which connects the air inlet 22 to the storage cavity 20, is a quick-freezing drawer 27. Since the quick-freezing drawer 27 usually stores items such as ice packs that require low temperatures and are not afraid of drying due to their outer packaging, when the first drawer 21 is a quick-freezing drawer 27, its air inlet 22 is particularly suitable to connect with the storage cavity 20 to effectively meet the quick-freezing needs of items such as ice packs that are not afraid of drying.

[0114] When the air inlet 22 of the first drawer 21 is connected to other parts of the first drawer 21 except for the storage cavity 20, the cold air does not directly enter the storage cavity 20 of the first drawer 21, but reaches other parts of the first drawer 21. Because the cold air does not directly contact the items in the storage cavity 20 of the first drawer 21 in this case, it is not easy to cause the items to dry out. Therefore, it is especially suitable for drawers such as the flash freezer drawer 26 used to store items that are afraid of drying out.

[0115] As an example of the air inlet 22 of the first drawer 21 communicating with other parts of the first drawer 21 except for the storage cavity 20, see Figure 3 and Figure 4 In some embodiments, the cavity wall 263 of the first drawer 21, which forms the storage cavity 20, is provided with a cooling channel 261. The air inlet 22 of the first drawer 21 is connected to the cooling channel 261, so that cold air flows into the cooling channel 261 through the air inlet 22 of the first drawer 21. In this case, the cold air does not flow directly into the storage cavity 20 of the first drawer 21, but flows into the cavity wall 263 to cool the items in the storage cavity 20. In this case, the cooling and preservation requirements of the items can be met, and the direct blowing of cold air can be prevented from taking away moisture and causing the items to dry out, thus improving the preservation effect.

[0116] Specifically, see [link to relevant documentation] Figure 3 and Figure 4 In some embodiments, cooling channels 261 are provided in the left and right side walls 263 of the first drawer 21. These cooling channels 261 are connected to different air inlets 22 on the first drawer 21, allowing cold air to flow into the cooling channels 261 in the left and right side walls 263. This allows cold air to flow into the left and right side walls of the first drawer 21, indirectly cooling the items inside from both sides. Compared to cooling from only one side, this method is more efficient and provides better uniformity, thus improving the cooling effect.

[0117] The first drawer 21 with a cooling channel 261 inside the aforementioned cavity wall 263 can be a flash-freezing drawer 26. This can meet the temperature requirements of the flash-freezing drawer 26 while preventing cold air from blowing directly into the meat and other items inside the flash-freezing drawer 26, thus making the meat and other items inside the flash-freezing drawer 26 fresher and more nutritious, and achieving a better flash-freezing effect.

[0118] In the foregoing embodiments, the positional relationship between the air duct component 7 and the first drawer 21 is not limited; they can be arranged side-by-side or front-to-back. As one example, see [link to relevant documentation]. Figure 1 and Figure 2 In some embodiments, the air duct component 7 is located on the rear side of the first drawer 21. Thus, the air outlet 741 on the air duct component 7 is located on the rear side of the first drawer 21, in the direction of pushing and pulling the first drawer 21. The direction of the air duct component 7 relative to the first drawer 21 is consistent with the pushing direction. Therefore, it is easier for the air outlet 741 to engage and disengage with the air inlet 22 of the first drawer 21 during the pushing and pulling process. It is also easier for the first drawer 21 to compress the aforementioned sealing element 89 during the pushing and pulling process, forming an effective seal.

[0119] When the air duct component 7 is located on the rear side of the first drawer 21, the air inlet 22 on the first drawer 21 can be located on the rear wall of the first drawer 21 to further facilitate the engagement and separation of the air inlet 22 on the first drawer 21 and the air outlet 471 on the air duct component 7 during the pushing and pulling of the first drawer 21.

[0120] As a further improvement to the foregoing embodiments, see Figures 1-17 The refrigerator 100 contains not only a first compartment 11 but also a second compartment 12. The second compartment 12 and the first compartment 11 are arranged along a vertical Z-axis. The air duct component 7 has not only an air outlet 741 but also an air supply outlet 772. The refrigerator 100 also includes an air guide component 5, which is positioned above the second compartment 12 and contains an air guide duct 55. The air guide duct 55 includes a first air duct 551 and a second air duct 552. The first air duct 551 and the second air duct 552 are arranged at an angle to each other and both connect to the air supply outlet 772 and the second compartment 12, guiding the cold air flowing through the air supply outlet 772 into the air guide component 5 from different positions into the second compartment 12. It can be understood that "at an angle" means not collinear; that is, the angle between the two is greater than 0° and less than 180°.

[0121] In the above configuration, the second compartment 12 does not use the same direct air supply cooling method as the first compartment 11, but still uses the traditional direct air supply cooling method. However, since the first air duct 551 and the second air duct 552 of the air duct 55 are arranged at an angle to each other and are both connected to the air supply port 772 and the second compartment 12, the first air duct 551 and the second air duct 552 can divert the cold air supplied by the air duct component 7 and guide the diverted cold air to flow into the second compartment 12 from different positions, so that the cooling capacity is more evenly distributed in the second compartment 12. Therefore, the cooling uniformity of the second compartment 12 can be improved and the cooling effect of the second compartment 12 can be enhanced.

[0122] In particular, the air duct 55 is located in the air guide 5 that is already located at the top of the second chamber 12, without taking up additional space. Therefore, this method of using the air duct 55 to guide air to the second chamber 12 is particularly suitable for the second chamber 12 with a small space. For example, the space is generally smaller as the box 1 goes lower, and the space at the bottom of the box 1 is smaller. Therefore, the space below the first chamber 11, especially the chamber at the bottom of the box 1, is particularly suitable for use as the second chamber 12, and is equipped with the air guide 5 with the air duct 55 inside, to obtain cold air and improve the uniformity of cold distribution. For example, in some embodiments, a compressor compartment (i.e. a compartment for housing the compressor) is provided at the rear of the space at the bottom of the housing 1, and the corresponding bottom space is used as a second compartment 12. In this case, the second compartment 12 is located at the bottom of the housing 1, and the space in the second compartment 12 is small. In this case, equipping the second compartment 12 with an air guide 5 having an internal air guide duct 55 can improve the uniformity of the cooling distribution in the second compartment 12 while occupying less space.

[0123] The length direction (or extension direction) of the first air duct 551 and the second air duct 552 is not limited. They can be along the front-back direction X or the left-right direction Y, or they can be at an angle to the front-back direction X or the left-right direction Y, that is, they are inclined relative to the front-back direction X or the left-right direction Y.

[0124] For example, see Figure 11 In some embodiments, the first air duct 551 extends along the left-right direction Y. In this way, the first air duct 551 can guide the cold air entering the air guide 5 to extend along the left-right direction Y, expanding the coverage area of ​​the cold air in the left-right direction Y and improving the uniformity of the cooling distribution in the second chamber 12. In particular, when the air supply port 772 (corresponding to the air inlet 53 on the air guide 5) is located on the left-right direction Y side, the first air duct 551 can guide the airflow away from flowing to the other side of the left-right direction Y where the air supply port 772 is not located, allowing the cold air to flow over a larger area in the left-right direction Y and improving the uniformity of the cooling distribution.

[0125] Additionally, see Figure 11 In some embodiments, the second air duct 552 extends along the front-rear direction X. In this way, the second air duct 552 can guide the cold air entering the air guide 5 to extend along the front-rear direction X, expanding the coverage area of ​​the cold air in the front-rear direction X and improving the uniformity of the cooling distribution in the second compartment 12. In particular, the second air duct 552 extending along the front-rear direction X can guide the airflow to flow towards the opposite side of the air supply port 772 when the air supply port 772 (corresponding to the air inlet 53 on the air guide 5) is located on the rear side, allowing the cold air to flow over a larger area in the front-rear direction X and improving the uniformity of the cooling distribution.

[0126] See also Figure 11 In some embodiments, the air duct 55 includes not only the first air duct 551 and the second air duct 552, but also a third air duct 553. The third air duct 553 and the second air duct 552 are connected to opposite ends of the first air duct 551, and the third air duct 553 is connected to the first air duct 551 at an angle and communicates with the air supply port 772 through the first air duct 551. In this way, after the cold air enters the air guide 5, it can not only be diverted and guided by the first air duct 551 and the second air duct 552, but also have its direction changed by the third air duct 553 when it flows out of the first air duct 551. This helps to further expand the flow range of the cold air, guide the cold air to flow more fully through the second compartment 12, improve the uniformity of cold distribution, and improve the cooling effect.

[0127] The third air duct 553 can be configured in various ways.

[0128] For example, see Figure 11 In some embodiments, the third air duct 553 and the second air duct 552 are parallel to each other. In this way, the third air duct 553 can guide the cold air flowing out of the first air duct 551 to flow in a direction parallel to the second air duct 552, so that the cold air can flow parallel to both sides of the first air duct 551 and enter the second compartment 12, thereby improving the uniformity of cold distribution and enhancing the cooling effect.

[0129] See also Figure 11 In some embodiments, the third air duct 553 and the second air duct 552 bend to the same side relative to the first air duct 551. In this way, the third air duct 553 can guide the cold air flowing out of the first air duct 551 to flow in the direction of the cold air flow in the second air duct 552, forming a roughly П-shaped flow path inside the air guide 5, guiding the cold air to flow more fully through the second compartment 12, improving the uniformity of cold distribution and improving the cooling effect.

[0130] In the aforementioned embodiments, the air duct 55 can be implemented by setting a partition plate 59 inside the air guide 5, which cleverly utilizes the internal space of the air guide 5 to achieve uniform distribution of cooling capacity in a limited space and improve the cooling effect.

[0131] As an improvement, baffles can be further installed in the air guide duct 55 to further divide the air guide duct 55, so as to achieve more precise guidance of cold air, more fully guide the cold air to be evenly distributed, improve the uniformity of cold air distribution, and improve the cooling effect.

[0132] For example, see Figure 11In some embodiments, a first partition 56 is provided in the first air duct 551, which divides the first air duct 551 in the width direction. In this way, the cold air entering the first air duct 551 can be further diverted by the first partition 56, and guided by different parts in the width direction of the first air duct 551, it flows more fully through different areas of the second compartment 12, improving the uniformity of cold distribution and improving the cooling effect.

[0133] For example, see Figure 11 In some embodiments, a second partition 57 is provided in the second air duct 552, which divides the second air duct 552 in the width direction. In this way, the cold air entering the second air duct 552 can be further diverted by the second partition 57, and guided by different parts in the width direction of the second air duct 552, it flows more fully through different areas of the second compartment 12, improving the uniformity of cold air distribution and improving the cooling effect.

[0134] For example, see Figure 11 In some embodiments, a third partition 58 is provided in the third air duct 553, which divides the third air duct 553 in the width direction. In this way, the cold air entering the third air duct 553 can be further diverted by the third partition 58, and guided by different parts in the width direction of the third air duct 553, it flows more fully through different areas of the second compartment 12, improving the uniformity of cold air distribution and improving the cooling effect.

[0135] In the foregoing embodiments, the second chamber 12 can be a variable temperature chamber 15 to improve the uniformity of cold distribution in the variable temperature chamber 15 and improve the cooling effect of the variable temperature chamber 15.

[0136] The following will provide further details. Figures 1-17 The example shown.

[0137] like Figure 1 As shown, in this embodiment, the refrigerator 100 has a lower freezer compartment inside its body 1, which is divided into a first compartment 11, a third compartment 13, and a second compartment 12 arranged sequentially from top to bottom. The first compartment 11, the third compartment 13, and the second compartment 12 serve as the freezer compartment 14, the deep freezer compartment 16, and the variable temperature compartment 15, respectively, arranged sequentially along the vertical direction Z, forming the upper, middle, and lower compartments of the freezer compartment. At this time, the freezer compartment 14 (first compartment 11) is located at the top of the freezer compartment, and the variable temperature compartment 15 (second compartment 12) is located at the bottom of the freezer compartment, which is also the bottom of the body 1. In this embodiment, a compressor compartment is located behind the variable temperature compartment 15 (second compartment 12), therefore, the space in the variable temperature compartment 15 (second compartment 12) is relatively small.

[0138] Depend on Figure 1 As can be seen, in this embodiment, the freezer compartment is equipped with a rotatable and closable door 91. The door 91 controls the opening and closing of the entire freezer compartment; that is, the opening and closing of the first compartment 11, the third compartment 13, and the second compartment 12 are controlled by the door 91 as a whole. When the door 91 is open, the front ports of the first compartment 11, the third compartment 13, and the second compartment 12 are all open. When the door 91 is closed, the front ports of the first compartment 11, the third compartment 13, and the second compartment 12 are all closed.

[0139] like Figure 1 As shown, in this embodiment, a detection element 93 is provided on the door 91 to detect whether the door 91 is open. When the door 91 is detected to be closed, all the fans 80 and all the dampers 92 mentioned below are opened to supply air for cooling and meet the cooling requirements; when the door 91 is detected to be open, all the fans 80 and all the dampers 92 mentioned below are closed to save energy.

[0140] like Figure 1 and Figure 2 As shown, in this embodiment, a drawer assembly 2 is provided in the first compartment 11. The drawer assembly 2 includes a drawer drawer 23, three drawers 17, and a drawer cover 28. The drawer drawer 23 is movably disposed in the first compartment 11 via slide rails or the like. The three drawers 17 are two first drawers 21 and one ice-making drawer 29, which are arranged side by side in the drawer drawer 23 along the left-right direction Y, so that when the drawer drawer 23 is pushed or pulled, the ice-making drawer 29 and the two first drawers 21 can move back and forth together, moving between the pulled-out position and the pushed-in position. The pulled-out position and the pushed-in position are the extreme positions of pulling out and pushing in, respectively.

[0141] Specifically, by Figure 1 and Figure 2 As can be seen, in this embodiment, the two first drawers 21 are a flash-freezing drawer 26 (preset cooling temperature -5℃) and a quick-freezing drawer 27 (preset cooling temperature -18℃), respectively. The flash-freezing drawer 26, the quick-freezing drawer 27, and the ice-making drawer 29 (preset cooling temperature -50℃) are arranged sequentially in the drawer compartment 23 from left to right. At this time, in the left-right direction Y, the quick-freezing drawer 27 is located in the middle, and the flash-freezing drawer 26 and the ice-making drawer 29 are located on both sides, on the outer side. The drawer compartment 23 can drive the flash-freezing drawer 26, the quick-freezing drawer 27, and the ice-making drawer 29 to move back and forth between the pulled-out position and the pushed-in position.

[0142] like Figure 2 As shown, the top of each of the two first drawers 21, which are respectively used as the flash-freezing drawer 26 and the quick-freezing drawer 27, is provided with a drawer cover 28 to close the top opening of the two first drawers 21 and prevent air leakage.

[0143] In addition, by Figure 1 and Figure 2 As can be seen, in this embodiment, each of the second compartment 12 and the third compartment 13 has only one drawer 17, namely the second drawer 3 and the third drawer 4. Specifically, the second drawer 3 and the third drawer 4 are the variable temperature drawer 31 and the deep freezer drawer 41 (preset cooling temperature -42℃), respectively.

[0144] As can be seen, in this embodiment, the freezing area is provided with five drawers 17, namely two first drawers 21 used as flash-freezing drawer 26 and quick-freezing drawer 27, a second drawer 3 used as variable temperature drawer 31, a third drawer 4 used as deep-freezing drawer 41, and an ice-making drawer 29.

[0145] Among them, the cooling requirements of the ice drawer 29 are quite different from those of the other drawers. It adopts a different cooling method than the other drawers, such as using a cold source other than the cooling system 6 mentioned below, which will not be described in detail here.

[0146] The following section will focus on the cooling methods of the four drawers other than the ice maker drawer 29.

[0147] In this embodiment, the two first drawers 21, which are used as the flash-freezing drawer 26 and the quick-freezing drawer 27 respectively, adopt a cooling method of direct air intake without passing through the first compartment 11, so as to realize flash-freezing and quick-freezing temperature zones directly cooled in the same compartment, achieving efficient and uniform flash-freezing and quick-freezing effects with less space. The second drawer 3, which is used as the variable temperature drawer 31, and the third drawer 4, which is used as the deep-freezing drawer 41, adopt a traditional cooling method of air supply through the compartment. However, considering the small space of the variable temperature compartment 15, the air duct 55 in the air guide 5 is used to even out the cooling load, so as to improve the uniformity of cooling load distribution and improve the cooling effect of the variable temperature compartment.

[0148] Specifically, such as Figures 3-5 As shown, each of the two first drawers 21, which are used as the flash-freezing drawer 26 and the quick-freezing drawer 27 respectively, is provided with an air inlet 22 and an air outlet 221 for supplying cold air to and out of the two first drawers 21 used as the flash-freezing drawer 26 and the quick-freezing drawer 27.

[0149] For easy distinction, the air inlet 22 and air outlet 221 on the flash freezer drawer 26 are called flash freezer air inlet 24 and flash freezer air outlet 241, respectively, while the air inlet 22 and air outlet 221 on the quick freezer drawer 27 are called quick freezer air inlet 25 and quick freezer air outlet 251, respectively.

[0150] like Figure 3As shown, the rear wall of the flash-freezing drawer 26 is provided with two flash-freezing air inlets 24 and two flash-freezing air outlets 241. The two flash-freezing air inlets 24 and two flash-freezing air outlets 241 are divided into two groups, each group including one flash-freezing air inlet 24 and one flash-freezing air outlet 241. Thus, the flash-freezing drawer 26 has two groups of flash-freezing air inlets 24 and flash-freezing air outlets 241. The two groups of flash-freezing air inlets 24 and flash-freezing air outlets 241 are arranged alternately along the left-right direction Y on the rear wall of the flash-freezing drawer 26, and each group of flash-freezing air inlets 24 and flash-freezing air outlets 241 includes one flash-freezing air inlet 24 and one flash-freezing air outlet 241. In the same group of flash-freezing air inlets 24 and flash-freezing air outlets 241, the flash-freezing air inlets 24 are located above the flash-freezing air outlets 241.

[0151] And, as Figure 4 As shown, cooling channels 261 are provided in the left and right side walls 263 of the flash-freezing drawer 26. The cooling channels 261 on both sides are connected to two sets of flash-freezing air inlets 24 and flash-freezing air outlets 241, respectively, so that cold air can be introduced into the left and right side walls 263 of the flash-freezing drawer 26. In this way, the left and right side walls of the flash-freezing drawer 26 can be cooled, preventing the items in the flash-freezing drawer 26 from directly contacting the air and drying out, so as not to affect the quality of the flash-frozen items.

[0152] Specifically, by Figure 4 As can be seen, in this embodiment, a flow channel plate 262 is provided inside the cooling channel 261. The flow channel plate 262 extends along the length of the cooling channel 261, but does not extend the entire length of the cooling channel 261, so that the cooling channel 261 is divided into upper and lower flow channel segments by the flow channel plate 262. These two flow channel segments are separated from each other at the rear end and are respectively connected to the instantaneous freezing air inlet 24 and the instantaneous freezing air outlet 241, while they are connected to each other at the front end, thus achieving the desired effect. Figure 13 and Figure 14 As shown by the middle arrow, the cold air reaching the flash-freezing air inlet 24 can enter the cooling channel 261 through the upper flow channel section, bypass the end of the flow channel plate 261, and then flow from the lower flow channel section to the flash-freezing air outlet 241, and flow out to the outside of the cooling channel 261, thus achieving the wall cooling effect.

[0153] Figure 5 The structure of the first drawer 21, which serves as the quick-freezing drawer 27, is further shown. (As shown) Figure 5 As shown, in this embodiment, the first drawer 21, which serves as the quick-freezing drawer 27, has only one air inlet 22 and one air outlet 221 on its rear wall. That is, it has one quick-freezing air inlet 25 and one quick-freezing air outlet 251. The quick-freezing air inlet 25 and the quick-freezing air outlet 251 are arranged vertically, with the quick-freezing air inlet 25 located above the quick-freezing air outlet 251. Both are connected to the storage cavity 20 of the quick-freezing drawer 27 so that cold air can enter and exit the storage cavity 20 of the quick-freezing drawer 27 to directly contact and cool the items inside the quick-freezing drawer 27.

[0154] The two first drawers 21, which serve as flash-freezing drawer 26 and quick-freezing drawer 27, the second drawer 3, which serves as variable-temperature drawer 31, and the third drawer 4, which serves as deep-freezing drawer 41, are all cooled by the cooling system 6. The cooling system 6 is located at the rear of each drawer in the freezer compartment and is used to cool the four drawers in the freezer compartment except for the ice-making drawer 29.

[0155] Figures 6-9 as well as Figures 13-17 The structure of the cooling system 6 and its relationship with each drawer are further illustrated.

[0156] like Figures 6-9 As shown, in this embodiment, the cooling system 6 includes an air duct 7, two fans 80 (i.e., the first fan 81 and the second fan 82), and two evaporators 8 (i.e., the first evaporator 83 and the second evaporator 84). The two fans 80 and the two evaporators 8 are all mounted on the air duct 7 and are used to supply cold air to the four drawers through the air duct 7.

[0157] Specifically, such as Figures 6-9 As shown, in this embodiment, the air duct component 7 includes a housing 71, an end cap 72, and an air duct plate 73. The housing 71 and the end cap 72 are disposed opposite each other in the front-rear direction X. The housing 71 is located behind the end cap 72. The end cap 72 covers the front opening of the housing 71. The air duct plate 73 is disposed between the housing 71 and the end cap 72.

[0158] Depend on Figure 8 As can be seen, in this embodiment, the housing 71 is provided with two vents, namely a first vent 751 and a second vent 771. The first vent 751 and the second vent 771 are arranged at intervals along the left-right direction Y, and are blocked by a baffle plate to prevent airflow from interfering with each other. Furthermore, the first fan 81, the second fan 82, the first evaporator 83 and the second evaporator 84 are all disposed on the housing 71. The first evaporator 83 and the second evaporator 84 are both disposed on the back of the housing 71, located on the side of the housing 71 away from the air duct plate 73. Moreover, the first evaporator 83 and the first fan 81 are a group, disposed on the side of the first vent 751, and arranged sequentially below the first vent 751 in a bottom-to-top direction, for supplying cooling to the flash-freezing drawer 26, the quick-freezing drawer 27 and the deep-freezing drawer 41. The second evaporator 84 and the second fan 82 form another group, located on one side of the second vent 771, and arranged sequentially below the second vent 771 from bottom to top, for supplying cooling to the variable temperature drawer 31. At this time, the first evaporator 83 and the second evaporator 84 are arranged side-by-side along the left-right direction Y on the air duct component 7, located behind the freezer compartment 14 (first compartment 11), the deep freezer compartment 16 (third compartment 13), and the variable temperature compartment 15 (second compartment 12) in the freezing zone. Furthermore, combined with... Figure 8 and Figure 15 As can be seen, in this embodiment, the first evaporator 83 and the second evaporator 84 are located above the variable temperature chamber 15. At this time, the second evaporator 84, which is used to supply cooling to the variable temperature chamber 15, does not occupy the space of the variable temperature chamber 15, and is more suitable for the small space of the variable temperature chamber 15 due to the presence of a compressor compartment.

[0159] During operation, the first fan 81 drives the airflow through the first evaporator 83, cools it down to become cold air, and drives the corresponding cold air through the first vent 751 into the air duct component 7, so that it flows to the flash freeze drawer 26, quick freeze drawer 27 and deep freeze drawer 41 through the air outlet 741 and the interface 781 on the air duct plate 73 of the air duct component 7; while the second fan 82 drives the airflow through the second evaporator 84, cools it down to become cold air, and drives the corresponding cold air through the second vent 771 into the air duct component 7, so that it flows to the variable temperature drawer 31 through the air supply port 772 and other air outlets on the air duct plate 73 of the air duct component 7.

[0160] Depend on Figure 9 As can be seen, in this embodiment, the air duct plate 73 is provided with three sets of air supply outlets 741 and return air outlets 742. Among them, two sets of air supply outlets 741 and return air outlets 742 are used as two sets of flash-freezing air supply outlets 752 and flash-freezing return air outlets 753, corresponding to the two sets of air inlets 22 and air outlets 221 (i.e., two sets of flash-freezing air inlets 24 and flash-freezing air outlets 241) of the flash-freezing drawer 26. Specifically, the flash-freezing air supply outlets 752 correspond one-to-one with the flash-freezing air inlets 24, so as to connect the cooling channel 261 of the flash-freezing drawer 26 with the air duct component 7, and the air duct component 7 directly delivers cold air to the left and right side walls of the flash-freezing drawer 26 for cooling. The flash-freezing return air vent 753 corresponds one-to-one with the flash-freezing air outlet 241, so that the airflow after cooling the left and right side walls of the flash-freezing drawer 26 flows out from the cooling channel 261, through the flash-freezing air outlet 241 to the flash-freezing return air vent 753 for return air. In addition, the remaining set of air inlets 741 and return air inlets 742 are used as quick-freezing air inlets 761 and quick-freezing return air inlets 762, corresponding to the air inlet 22 and air outlet 221 (i.e., quick-freezing air inlet 25 and quick-freezing air outlet 251) of the quick-freezing drawer 27. Specifically, the quick-freezing air inlet 761 corresponds to the quick-freezing air inlet 25 to connect the storage cavity 20 of the quick-freezing drawer 27 to the air duct component 7, so that cold air is delivered to the storage cavity 20 of the quick-freezing drawer 27 for cooling. The quick-freeze return air vent 762 corresponds to the quick-freeze air outlet 251, so that the airflow from the storage cavity 20 of the quick-freeze drawer 27 flows through the quick-freeze air outlet 221 to the quick-freeze return air vent 762 for return air.

[0161] More specifically, in combination Figures 6-7 , Figure 9 as well as Figures 13-16As can be seen, in this embodiment, each air supply port 741 and each return air port 742 protrudes forward from the air duct plate 73. Correspondingly, the end cover 72 located on the front side of the air duct plate 73 is provided with through holes, allowing each air supply port 741 and each return air port 742 to extend to the outside of the end cover 72 and respectively connect with each air inlet 22 and each air outlet 221, so that each air supply port 741 and each air inlet 22 and each return air port 742 and each air outlet 221 can be separately connected. Thus, each air supply port 741 and each air inlet 22 and each return air port 742 and each air outlet 221 can be connected or separated as their respective drawers (i.e., the flash freezer drawer 26 and the quick freezer drawer 27) are pushed and pulled, forming a movable air duct structure.

[0162] Among them, such as Figure 13 and Figure 14 As shown, in this embodiment, the instantaneous freezing air inlet 752 and the instantaneous freezing air inlet 24, as well as the instantaneous freezing return air inlet 753 and the instantaneous freezing air outlet 241, are connected to each other, enabling the detachable engagement between the air inlet 22 and the air outlet 221 of the instantaneous freezing drawer 26 and the instantaneous freezing air inlet 752 and the instantaneous freezing return air inlet 753 of the air duct component 7. This allows the instantaneous freezing air inlet 752 and the instantaneous freezing air inlet 24, as well as the instantaneous freezing return air inlet 753 and the instantaneous freezing air outlet 241, to be inserted into each other for connection and ventilation cooling when the drawer 23 is pushed inward and the instantaneous freezing drawer 26 is pulled out to the pulled-out position. This allows the instantaneous freezing air inlet 752 and the instantaneous freezing air inlet 24, as well as the instantaneous freezing return air inlet 753 and the instantaneous freezing air outlet 241, to be separated, cutting off the corresponding air ducts and stopping the instantaneous freezing cooling.

[0163] And such Figure 15 and Figure 16 As shown, in this embodiment, the quick-freezing air inlet 761 and quick-freezing air inlet 25, as well as the quick-freezing return air inlet 762 and quick-freezing air outlet 251, are connected to achieve a separable connection between the air inlet 22 and air outlet 221 of the quick-freezing drawer 27 and the quick-freezing air inlet 761 and quick-freezing return air inlet 762 of the air duct component 7. This allows the quick-freezing air inlet 761 and quick-freezing air inlet 25, as well as the quick-freezing return air inlet 762 and quick-freezing air outlet 251, to be inserted into each other for connection and ventilation and cooling when the drawer 23 is pushed inward and the quick-freezing drawer 27 is pulled out to the pulled-out position. This allows the quick-freezing air inlet 761 and quick-freezing air inlet 25, as well as the quick-freezing return air inlet 762 and quick-freezing air outlet 251, to be separated, cutting off the corresponding air ducts and stopping quick-freezing cooling.

[0164] Since the flash-freezing drawer 26 and the quick-freezing drawer 27 are arranged side by side in the drawer compartment 23 along the left-right direction Y, and move back and forth with the drawer compartment 23, the flash-freezing drawer 26 and the quick-freezing drawer 27 can be pushed in or pulled out synchronously simply by pushing and pulling the drawer compartment 23. This allows for the synchronous engagement or disengagement of the movable air ducts corresponding to the flash-freezing drawer 26 and the quick-freezing drawer 27, making it convenient for the flash-freezing drawer 26 and the quick-freezing drawer 27 to start and stop refrigeration at the same time.

[0165] Moreover, since the flash-freezing drawer 26 and the quick-freezing drawer 27 obtain cooling capacity through movable air ducts, and the corresponding movable air ducts can be disconnected when the flash-freezing drawer 26 and the quick-freezing drawer 27 are pulled out, the flash-freezing drawer 26 and the quick-freezing drawer 27 can be removed from the cabinet 1 after being pulled out for cleaning or replacement. This not only makes them convenient to use, but also helps to further improve the cooling effect.

[0166] In addition, by Figures 13-16 As can be seen, in this embodiment, each air inlet 741 and each air outlet 742 is provided with a sealing element 89 to seal the air intake, reduce cold leakage, and improve the cooling effect. For easy distinction, the sealing elements 89 corresponding to the flash freezer drawer 26 and the quick freezer drawer 27 can respectively become the first sealing element 85 (see...). Figure 14 ) and second seal 86 (see Figure 16 ).

[0167] The structures of each seal 89 can be the same or different. In this embodiment, at least some seals 89 include a sleeve 87 and a flange 88. The flange 88 is located at the end of the sleeve 87 away from the first drawer 21 and is folded relative to the sleeve 87 to form a flange, making the corresponding seal 89 approximately Ω-shaped. Thus, when the drawer 23 is pushed, causing the blast freezer drawer 26 and the quick-freeze drawer 27 to move backward, the blast freezer drawer 26 and the quick-freeze drawer 27 can compress the seals 89 on the corresponding air inlets 741 and air outlets 742, automatically forming a tight seal, enhancing the sealing performance of the movable air duct structure, reducing cold leakage, and effectively cooling. Because the approximately Ω-shaped seals 89 can be more fully compressed and more tightly sealed, they are more conducive to reducing cold leakage and improving the cooling effect.

[0168] Additionally, returning Figure 9 In this embodiment, each air outlet 741 is provided with a damper 92 to control whether each air outlet 741 is open, thereby controlling whether each air outlet 741 is connected to each air inlet 22, so as to control whether to supply cooling to the blast freezer drawer 26 and the quick freezer drawer 27.

[0169] During operation, if the blast freezer drawer 26 and the quick-freeze drawer 27 are pushed to the advanced position, the dampers 92 at the air outlets 741 corresponding to the blast freezer drawer 26 and the quick-freeze drawer 27 will open. This allows the cold air entering the air duct component 7 under the drive of the first fan 81 to flow through the connected air outlets 741 to the blast freezer air inlets 24 and the quick-freeze air inlets 25, respectively, to perform wall cooling and direct contact air cooling on the blast freezer drawer 26 and the quick-freeze drawer 27. After a period of ventilation, since the preset cooling temperature of the blast freezer drawer 26 is higher, it will reach its preset cooling temperature first. At this time, the dampers 92 at the air outlets 741 corresponding to the blast freezer drawer 26 will be closed to stop supplying cold to the blast freezer drawer 26, while the dampers 92 corresponding to the quick-freeze drawer 27 will remain open to continue supplying cold to the quick-freeze drawer 27, so that the quick-freeze drawer 27 reaches its own preset cooling temperature.

[0170] See also Figure 9 In this embodiment, the air duct plate 73 is also provided with two sets of connection ports 781 and return ports 782. Both sets of connection ports 781 and return ports 782 are connected to the deep freeze chamber 16, so that the cold air flowing into the air duct component 7 under the drive of the first fan 81 can flow into the deep freeze chamber 16 via the two sets of connection ports 781, and transfer cold energy from the deep freeze chamber 16 to the deep freeze drawer 41 inside the deep freeze chamber 16 for cooling. The cooled airflow can flow out from the deep freeze drawer 41 and return via the two sets of return ports 782. Each connection port 781 is also provided with a damper 92 to control whether cold air is supplied to the deep freeze chamber 16, facilitating the control of the deep freeze chamber 16 to reach and maintain the required preset cooling temperature.

[0171] As can be seen, in this embodiment, the deep-freeze compartment 16 and the flash-freeze drawers 26 and 27 arranged side-by-side in the freezer compartment 14 are all cooled by the same fan 80 and evaporator 8, resulting in a simpler structure, fewer components, and lower cost. Since the flash-freeze drawers 26 and 27 are arranged in the same compartment and both directly obtain cold air from the ductwork 7 through a movable duct structure, without needing to transfer cold air through their respective compartments, the cooling efficiency is higher, the cooling effect is better, and they occupy less space.

[0172] Although Figure 9 As shown in this embodiment, the set of interfaces 781 and return ports 782 corresponding to the quick-freezing return air inlet 762 and the deep-freezing chamber 16 are located on the side close to the second fan 82. However, it should be understood that the corresponding gas flow path will not be affected by the second fan 82 and will not be able to deliver and return air smoothly. This is because the air duct component 7 is actually equipped with a barrier to separate the set of interfaces 781 and return ports 782 corresponding to the quick-freezing return air inlet 762 and the deep-freezing chamber 16 from the flow path corresponding to the second fan 82, so that the two airflows do not affect each other and can deliver and return air smoothly.

[0173] See also Figure 9 In this embodiment, the air duct plate 73 is also provided with an air supply port 772 and an air return port 773. The air supply port 772 and the air return port 773 are located on one side of the second fan 82 in the left-right direction Y, and are arranged below the second fan 82 in the direction from top to bottom. They are respectively used to communicate with the air inlet 53 on the air guide 5 located above the variable temperature chamber 15 and the variable temperature chamber 15, so that the airflow can flow into the interior of the air guide 5. Under the guidance of the air guide duct 55 inside the air guide 5, the air carries the cold air through the entire variable temperature chamber 15, improving the cooling uniformity of the variable temperature chamber 15. After circulating through the variable temperature chamber 15 and completing the cooling of the variable temperature drawer 31, the air is returned from the air return port 773.

[0174] Combination Figure 9 , Figure 7 and Figure 6 As can be seen, in this embodiment, the air supply port 772 protrudes forward from the air duct plate 73 and extends to the outside of the end cover 72. This facilitates the cooperation between the air supply port 772 and the air inlet 53 on the air guide 5, connecting the air guide duct 55 inside the air guide 5 with the air duct 7, and supplying cold air to the variable temperature chamber 15.

[0175] Figures 10-12 The structure of the air guide 5 is shown.

[0176] like Figures 10-12 As shown, in this embodiment, the air guide 5 includes a first plate 51 and a second plate 52. The first plate 51 is open downwards, and the second plate 52 covers the lower opening of the first plate 51, forming an inner cavity together with the first plate 51. An air inlet 53 is provided on the rear wall of the inner cavity, and the air inlet 53 communicates with the air supply port 772 on the air duct 7. Specifically, see [link to documentation]. Figure 17 An air supply port 772 is inserted into an air inlet 53 to allow air to pass through the air inlet 53 into the inner cavity. Furthermore, a partition plate 59 is provided in the inner cavity. The partition plate 59 is generally H-shaped and is arranged on a first plate 51 and a second plate 52 to divide the inner cavity into an air guide duct 55, which includes a first air duct 551, a second air duct 552 and a third air duct 553.

[0177] The first air duct 551 is located at the rear of the inner cavity, communicating with the air inlet 53, and extending along the left-right direction (Y). The second air duct 552 and the third air duct 553 are located at opposite ends of the first air duct 551, and both bend forward from the first air duct 551, making the first air duct 551, second air duct 552, and third air duct 553 roughly Π-shaped together. Specifically, the second air duct 552 and the third air duct 553 are located on the left and right sides of the first air duct 551. The second air duct 552 is separated from the first air duct 551 by a partition plate 59 and is not connected to it, while the third air duct 553 is connected to the first air duct 551, so that the third air duct 553 is connected to the air inlet 53 through the first air duct 551. Furthermore, the second air duct 552 and the third air duct 553 are parallel to each other, both extending along the front-back direction (X).

[0178] Based on the above settings, such as Figure 11 As shown by the arrow, the airflow entering the air guide 5 from the air inlet 53 is divided into two streams by the partition plate 59. One stream enters the second air duct 552 located on the left-right side and flows from back to front along the second air duct 552. The other stream first enters the first air duct 551 and, guided by the first air duct 551, flows along the left-right direction Y towards the third air duct 553 located on the other side of the left-right direction. After reaching the third air duct 553, it flows from back to front under the guidance of the third air duct 553.

[0179] Since the airflow entering the air guide 5 will eventually flow from back to front in the second air duct 552 and the third air duct 553, therefore, Figure 12 As shown, in this embodiment, an air outlet 54 is provided on the portion of the second plate 52 facing the variable temperature chamber 15 (that is, the bottom wall of the second plate 52) corresponding to the tail of the second air duct 552 and the third air duct 553. The air outlet 54 connects the second air duct 552 and the third air duct 553 with the variable temperature chamber 15, so that when the airflow flows from back to front along the second air duct 552 and the third air duct 553 to the tail of the second air duct 552 and the third air duct 553, it can flow into the variable temperature chamber 15 through the air outlet 54 for cooling.

[0180] Combination Figure 11 and Figure 15 as well as Figure 17It is understood that, under the action of the first air duct 551, the second air duct 552 and the third air duct 553, the air guide duct 55 can guide the cold air to flow to both sides and the opposite side of the air intake direction of the air inlet 53 (or air supply port 772). Specifically, in this embodiment, the air guide duct 55 guides the cold air flowing into the air guide 5 from the rear air inlet 53 to flow on the left and right sides, and flows from back to front on both sides, and finally enters the variable temperature chamber 15 from the front side for cooling. The cooled airflow returns from the return air port 773 on the rear air duct 7. In this case, the airflow can carry the cold energy throughout the entire variable temperature chamber 15, effectively improving the uniformity of cold energy distribution and improving the cooling effect of the variable temperature chamber 15. In particular, because the air duct 55 allows the airflow to flow from the front side into the variable temperature chamber 15 and out of the variable temperature chamber 15 from the rear side for return air, the air inlet and return air of the variable temperature chamber 15 are at opposite ends of the air duct 5, specifically at the two ends of the air duct 5 in the front-rear direction X, which are far apart. This is more conducive to the airflow carrying the cold energy throughout the entire variable temperature chamber 15, improving the uniformity of cold energy distribution and improving the cooling effect of the variable temperature chamber 15.

[0181] Furthermore, the uniform cooling capacity of the variable temperature compartment 15 is achieved by installing a partition in the air guide 5, which is already located at the top of the variable temperature compartment 15, to construct an air guide duct 55. This eliminates the need for additional space and allows for uniform distribution of cooling capacity within the limited space of the variable temperature compartment 15, which is small due to the compressor compartment at the rear. This effectively improves the cooling effect of the variable temperature drawer 31 and optimizes the spatial layout for better cooling performance. Although the original air guide 5 is also located at the top of the variable temperature compartment 15, it lacks an internal air guide duct 55, resulting in uneven cooling capacity distribution. In particular, the air guide 5, located at the top of the variable temperature compartment 15 and equipped with an internal air guide duct 5, can cleverly cooperate with the second evaporator 84, which is located on the back of the air guide 7 and above the variable temperature compartment 15 due to space constraints. This allows airflow to enter the variable temperature compartment 15 from the front and exit from the rear for return air, improving the uniformity of cooling capacity distribution and enhancing the cooling effect of the variable temperature compartment 15.

[0182] And, as Figure 11 As shown, in this embodiment, the second plate 52 has multiple air outlets 54 on the portion of its surface facing the variable temperature chamber 15 (i.e., the bottom wall of the second plate 52) corresponding to the tail ends of the second air duct 552 and the third air duct 553. These multiple air outlets 54 are arranged side by side in the left-right direction Y, and each air outlet 54 is elongated (e.g., rectangular or oblong), with its long axis along the front-back direction X. In this way, cold air can flow from the front through multiple elongated air outlets 54 arranged in the left-right direction Y into the variable temperature chamber 15, resulting in more uniform airflow. Therefore, this is beneficial for further improving the uniformity of cold air distribution in the variable temperature chamber 15 and enhancing its cooling effect.

[0183] In addition, such as Figure 11 and Figure 12 As shown, in this embodiment, a first partition 56, a second partition 57, and a third partition 58 are respectively provided in the first air duct 551, the second air duct 552, and the third air duct 553. The first partition 56, the second partition 57, and the third partition 58 extend along the length direction of the first air duct 551, the second air duct 552, and the third air duct 553, and are respectively located at the middle of the width direction of the first air duct 551, the second air duct 552, and the third air duct 553, thus separating the first air duct 551, the second air duct 552, and the third air duct 553 in the width direction. In this case, the airflow can flow more evenly in the first air duct 551, the second air duct 552, and the third air duct 553. The process of the airflow flowing in the first air duct 551, the second air duct 552, and the third air duct 553 is also the process of the airflow flowing at the top of the variable temperature chamber 15. Therefore, by setting baffles in the first air duct 551, the second air duct 552, and the third air duct 553 to guide the airflow to flow more evenly in the first air duct 551, the second air duct 552, and the third air duct 553, it is beneficial to further improve the uniformity of the cold distribution in the variable temperature chamber 15, thereby improving the cooling effect of the variable temperature chamber 15.

[0184] As can be seen, this embodiment, by arranging two first drawers 21 side by side in the same compartment, which serve as the flash-freezing drawer 26 and the quick-freezing drawer 27 respectively, and by providing movable air ducts based on the air outlet 741 and the air inlet 22 for the two first drawers 21 respectively, can not only realize the disassembly of the two first drawers 21 for easy cleaning and replacement, but also realize the direct transfer of cold energy from the air duct component 7 to the two first drawers 21, reducing cold energy loss, improving the uniformity of cold energy distribution, improving refrigeration efficiency, and improving refrigeration effect.

[0185] Furthermore, the movable air ducts corresponding to the two first drawers 21 are equipped with sealing elements 89 with flanges 88. When the two first drawers 21 are pushed in, the sealing elements 89 can be squeezed to automatically seal, which can further reduce the loss of cold energy and improve the cooling effect.

[0186] Furthermore, by setting a partition in the air guide 5 located at the top of the variable temperature compartment 15 to construct an air guide duct 55, the cooling capacity of the variable temperature compartment 15 can be evenly distributed. This can achieve uniform distribution of cooling capacity within a limited space, effectively improve the cooling effect of the variable temperature drawer 31, and improve the cooling performance of the refrigerator 100.

[0187] In addition, by intelligently controlling the door 91 and the damper 92, the fan 80 and the damper 92 can work normally when the door 91 is closed, and automatically close when the door 91 is open, which can achieve energy-saving operation and improve ease of use.

[0188] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this application.
