Description

Technical Field

[0001] The present application belongs to the technical field of electrical equipment, and in particular relates to a drawer and a refrigeration device. Background Art

[0002] The refrigeration drawer or temperature-controlled drawer of an air-cooled refrigerator typically features an independent air intake and return system for circulating cooling and temperature control. Since drawers typically slide back and forth, and the refrigerator's air ducts are often located at the rear of the refrigerator, the intake and return systems are typically located on the side of the drawer space near the back of the refrigerator. Considering the tendency of cold air to sink, the intake and return vents are located in the upper and lower areas of the drawer, respectively. This allows the incoming air to be fully distributed throughout the drawer and the return air to be stably collected, achieving both air-cooling effectiveness and circulating air efficiency.

[0003] Among them, the specifications of the return air vent match the air duct structure inside the refrigerator, so the specifications of the return air vent are usually smaller; during use, when there is a lot of food and materials stored in the drawer, the return air vent at the bottom of the drawer is easily blocked by the stored food or materials, or even blocked, affecting the air cooling circulation effect, resulting in unsatisfactory refrigeration effect. Summary of the Invention

[0004] The present application provides a drawer and a refrigeration device, which aims to at least to some extent solve the technical problem that the return air vents in the refrigerator refrigeration drawer are easily blocked by stored items, resulting in poor ventilation.

[0005] In one aspect of an embodiment of the present application, a drawer is provided, comprising:

[0006] ontology;

[0007] The return air cavity is arranged on the main body, and the return air cavity is provided with a return air window and a return air collection port, and the area of the return air window is larger than the area of the return air collection port, so that the airflow in the main body enters the return air cavity through the return air window, and then is collected and discharged from the return air collection port.

[0008] In some embodiments, the return air cavity is arranged on the inner side of the side wall of the body.

[0009] In some embodiments, the return air cavity includes:

[0010] The box body is formed on the inner side of the side wall of the main body, and the return air collection port is opened on the side wall of the main body;

[0011] The cover body is buckled on the box body, and the return air window is opened on the cover body.

[0012] In some embodiments, the return air cavity is arranged on the outer side of the side wall of the body.

[0013] In some embodiments, the return air cavity includes:

[0014] The box body is formed on the outer side surface of the side wall of the body, and the return air window is opened on the side wall of the body;

[0015] The cover body is buckled on the box body, and the return air collection port is opened on the cover body.

[0016] In some embodiments, a first filter element is provided at the return air window.

[0017] In some embodiments, the width of the return air window is 50% to 80% of the width of the inner cavity of the main body.

[0018] In some embodiments, the height of the return air window is less than or equal to 30% of the height of the inner cavity of the main body.

[0019] In some embodiments, the ventilation area of the return air window is about 8 to 30 times the ventilation area of the return air converging port.

[0020] Another aspect of the embodiments of the present application further provides a refrigeration device including the drawer.

[0021] The embodiments of the present application have at least the following beneficial effects:

[0022] The drawer and refrigeration device provided in the embodiment of the present application include a main body and a return air cavity provided on the main body, wherein the return air cavity is provided with a return air window and a return air collection port, and the airflow in the main body can flow into the return air cavity through the return air window, and then be collected at the return air collection port to flow out of the return air cavity and enter the return air flow channel of the refrigerator. The area of the return air window is larger than the area of the return air collection port. On the one hand, the return air collection port satisfies the matching connection between the drawer and the return air flow channel inside the refrigerator. On the other hand, the relatively larger return air window can be used to return air, thereby increasing the range of the area where air can be returned. To a certain extent, it increases the difficulty of the stored objects in the main body blocking or even blocking the return air window, thereby reducing the risk of the stored objects significantly blocking or even blocking the return air port, so that the return air area in the drawer is maintained above a certain level, ensuring the smoothness and efficiency of the return air, and thus maintaining the stability of the cooling effect.

[0037] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] In addition, this application may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0039] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0040] Air-cooled refrigerators often have air inlets and return vents in the refrigeration drawer or temperature-controlled drawer. These connect to the refrigerator's internal air duct, controlling the drawer's temperature through circulating air. The return vents are typically designed to match the refrigerator's internal flow path, resulting in a ventilation area much smaller than the drawer's inner wall area. Furthermore, the return vents are located in the lower area of the drawer, making them easily obstructed or even completely blocked by the drawer's stored items. This severely impacts the air circulation between the drawer and the refrigerator, resulting in suboptimal cooling.

[0041] To this end, the embodiments of the present application provide a drawer and a refrigeration device, which aim to solve, to a certain extent, the technical problem that the return air vent is easily blocked by stored items, resulting in poor cold air circulation and affecting the air cooling efficiency.

[0042] Figure 1 A first structural diagram of a drawer in an embodiment of the present application is shown; Figure 4 A second structural diagram of a drawer in an embodiment of the present application is shown; Figure 7 Shown Figure 4 Schematic diagram of the return air principle inside the drawer.

[0043] See also Figure 1 、 Figure 4 as well as Figure 7 In some embodiments, a chamber structure with a larger return air area can be provided on the drawer to reduce the risk of obstruction of the return air duct by stored items within the drawer. This allows the return air area within the drawer to remain above a certain level, thereby maintaining unobstructed cooling return air ducts inside and outside the drawer. The drawer may include a body 1 and a return air chamber 2 provided on the body 1. The return air chamber 2 may include a return air window 21 and a return air converging port 22.

[0044] The return air collection port 22 matches the circulating return air flow channel 3 inside a refrigeration device such as a refrigerator. When the drawer is installed in place, the return air collection port 22 is connected to the circulating return air flow channel 3.

[0045] The return air window 21 is arranged on the side of the return air cavity 2 close to the storage cavity 11 in the main body 1, so that the return air window 21 can be connected to the storage cavity 11 of the main body 1. The airflow in the main body 1 flows into the return air cavity 2 through the return air window 21, and then converges through the return air gathering port 22, continuously flows out of the return air cavity 2, and enters the circulating return air duct 3.

[0046] The circulating return air duct 3 has a lower air pressure than the storage cavity 11 of the main body 1, thereby forming a relatively negative pressure area, which can guide the airflow in the main body 1 through the return air window 21, and converge and flow out of the return air gathering port 22, and then enter the circulating return air duct 3.

[0047] The return air area of the return air window 21 is larger than the return air area of the return air gathering port 22, so that the return air window 21 has a larger ventilation area than the return air gathering port 22, and is more difficult to be significantly blocked in the main body 1, thereby reducing to a certain extent the risk of the return air window 21 being significantly blocked to threaten the smoothness of the return air, and maintaining the reliability and stability of the circulating air cooling.

[0048] The drawer and refrigeration device provided in the embodiment of the present application include a main body and a return air cavity provided on the main body, wherein the return air cavity is provided with a return air window and a return air collection port, and the airflow in the main body can flow into the return air cavity through the return air window, and then be collected at the return air collection port to flow out of the return air cavity and enter the return air flow channel of the refrigerator. The area of the return air window is larger than the area of the return air collection port. On the one hand, the return air collection port satisfies the matching connection between the drawer and the return air flow channel inside the refrigerator. On the other hand, the relatively larger return air window can be used to return air, thereby increasing the range of the area where air can be returned. To a certain extent, it increases the difficulty of the stored objects in the main body blocking or even blocking the return air window, thereby reducing the risk of the stored objects significantly blocking or even blocking the return air port, so that the return air area in the drawer is maintained above a certain level, ensuring the smoothness and efficiency of the return air, and thus maintaining the stability of the cooling effect.

[0050] See also Figure 1 、 Figure 2 and Figure 3 In some embodiments, in order to reduce the risk of interference between the return air cavity 2 and the surrounding structure of the drawer, the return air cavity 2 can be set in the storage cavity 11 inside the main body 1.

[0051] In some embodiments, in order to reduce the ventilation area of the return air window 21 that is blocked by the stored items, the return air cavity 2 can be set on the inner side of the side wall 12 of the main body 1.

[0052] In some embodiments, the return air cavity 2 may be disposed on a side wall of the body 1 that is closest to the circulating return air duct 3 in the refrigeration equipment.

[0053] In some embodiments, the return air cavity 2 can be configured as a split structure for ease of processing and cleaning. The return air cavity 2 can include a box body 23 and a cover body 24 .

[0054] The box body 23 can be disposed on the inner side surface of the side wall 12 of the main body 1 , and the cover body 24 is matched and snapped onto the box body 23 to form a closed box structure.

[0055] In some embodiments, in order to obtain a larger return air area, the return air window 21 may be opened on the cover 24 .

[0056] In some embodiments, the box body 23 can be formed on the inner side surface of the side wall 12 of the main body 1, that is, the side wall 12 is used as a side wall of the box body 23, and a first cylindrical structure 23a is protruded on the inner side surface of the side wall 12. The cover body 21 can be matched and snapped on the first cylindrical structure 23a to form a return air cavity 2.

[0057] In order to connect the return air cavity 2 with the circulating return air channel 3 in the refrigeration equipment, a return air collection port 22 may be opened on the side wall 12 of the main body 1 .

[0058] In some embodiments, the length of the first cylindrical structure 23a can be set to match the inner side length of the side wall 12 of the main body 1, so that the return air cavity 2 has a sufficiently large length; thereby, the return air window 21 can be set relatively larger to further increase the anti-blocking ability of the return air window 21.

[0060] join Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 In some embodiments, in order to prevent the return air cavity 2 from occupying the storage cavity 11 in the main body 1 , the return air cavity 2 may be disposed outside the main body 1 .

[0061] In some embodiments, in order to reduce the risk of interference with the surrounding structure of the drawer and maintain a larger ventilation cavity, the return air cavity 2 can be set on the outer surface of the side wall 12 of the main body 1.

[0062] In some embodiments, to enhance the structural strength of the drawer, a reinforcing ring rib 13 may be provided at the edge of the top port of the body 1. The return air chamber 2 may be positioned below the reinforcing ring rib 13, thereby improving the drawer's space utilization to a certain extent, adapting to the structure surrounding the drawer, and reducing the risk of interference.

[0063] In some embodiments, the return air cavity 2 can be configured as a split structure for ease of processing and cleaning. The return air cavity 2 can include a box body 23 and a cover body 24 .

[0064] The box body 23 can be disposed on the outer surface of the side wall 12 of the main body 1 , and the cover body 24 is matched and snapped onto the box body 23 to form a closed box structure.

[0065] A return air window 21 may also be opened on the cover 24 to adapt to connect to the circulating return air duct 3 .

[0066] In some embodiments, the box body 23 can be formed on the outer surface of the side wall 12 of the main body 1, that is, the side wall 12 is used as a side wall of the box body 23, and a second cylindrical structure 23b is protruded on the outer surface of the side wall 12. The cover body 21 can be matched and snapped on the second cylindrical structure 23b to form a return air cavity 2.

[0067] In order to connect the return air cavity 2 and the storage cavity 11 , a return air window 21 may be opened on the side wall 12 of the main body 1 .

[0068] In some embodiments, the length of the second cylindrical structure 23b can be set to match the length of the outer surface of the side wall 12 of the main body 1, so that the return air cavity 2 has a sufficiently large length; thereby, the return air window 21 can be set relatively larger to further increase the anti-blocking ability of the return air window 21.

[0069] In some embodiments, in order to facilitate assembly and disassembly of the cover 24, a snap-fit structure may be provided between the cover 24 and the box body 23, thereby facilitating assembly and disassembly.

[0070] In some embodiments, the hook 24 a may be disposed on the cover 24 , and a slot may be provided on the box 23 , in which the hook 24 a is engaged.

[0071] The positions of the hook 24a and the slot may also be interchanged, and there is no specific limitation here.

[0072] In some embodiments, considering that there is a long connection gap between the cover body 24 and the box body 23, in order to avoid sharp noise during the return air process due to the formation of an air gap, a seal may be provided on the cover body 24 and / or the box body 23 to seal the connection gap between the cover body 24 and the box body 23.

[0073] On the other hand, it can also avoid the connection gap between the sealing cover 24 and the box body 23 causing insufficient return air pressure in the return air cavity 2, thereby ensuring the reliability of return air.

[0074] In some embodiments, considering the diversity of the stored items in the main body 1 , in order to prevent small-sized items from entering the return air cavity 2 and blocking the connected flow path, a first filter element 25 may be provided at the return air window 21 .

[0075] In some embodiments, in order to facilitate processing and simplify installation, the first filter element 25 and the return air window 21 can be integrally formed.

[0076] In some embodiments, in order to prevent small particles from entering the return air cavity 2 , the upper limit of the pore size specification of the first filter element 25 may be set to 6 mm.

[0077] In order to prevent the pore size of the first filter element 25 from being too small and affecting ventilation smoothness, the lower limit of the pore size of the first filter element 25 can be set to 4 mm; thus, the pore size specification range of the first filter element 25 can be 4 mm to 6 mm.

[0078] In some embodiments, the first filter element 25 can be set as a grille plate 25a; accordingly, the width of the grille holes of the grille plate 25a ranges from 4mm to 6mm, and the length range of the grille holes can be flexibly set to take into account both ventilation fluency and structural strength performance.

[0079] In some embodiments, a second filter element 26 may be provided in the return air confluence port 22 to prevent debris from passing through. The aperture of the second filter element 25 may also be in the range of 4 mm to 6 mm.

[0080] In some embodiments, the second filter element 26 may also be integrally formed in the return air conduit 22 .

[0081] In some embodiments, the second filter element 26 may be configured as a filter grid.

[0082] In some embodiments, in order to facilitate connection to the circulating return air duct 3 in the refrigeration equipment, the return air collection port 22 can be set as a pipe. When connected to the circulating return air duct 3, the return air collection port 22 can be sleeved on the end connector of the circulating return air duct 3.

[0083] In some embodiments, the width of the storage cavity 11 of the main body 1 can be fully utilized, and the width of the return air window 21 can be set to be greater than or equal to 50% of the width of the inner cavity of the main body 1, which can form a larger ventilation area and reduce the risk of poor ventilation in the flow channel.

[0084] On the other hand, the width of the return air window 21 can be set to be less than or equal to 80% of the width of the inner cavity of the main body 1, so as to avoid the return air window 21 being too large in area, resulting in excessive dispersion of the air flow circulation and affecting the air flow flow; therefore, the width of the return air window 21 can be set to 50% to 80% of the width of the inner cavity of the main body 1.

[0085] In some embodiments, the return air window 21 may be disposed on a side close to the bottom of the body 1 to facilitate the return air to flow into the return air cavity 2 .

[0086] In order to prevent the return air window 21 from being too high, so that the incoming air flow is directly sucked into the return air window 21 and affects the circulation of the air flow in the storage cavity 11, the height of the return air window 21 can be set to 30% or less of the height of the main body cavity.

[0087] In some embodiments, the ventilation area of the return air window 21 can be set to about 8 to 30 times the ventilation area of the return air gathering port 22, that is, the return air area of the return air window 21 is much larger than the ventilation area of the return air gathering port 21, so as to fully improve the return air smoothness in the main body 1 and reduce the risk of poor return air.

[0088] In some embodiments, considering that the ventilation area of the return air window 21 may be much larger than the ventilation area of the return air gathering port 22, in order to reduce the local turbulence and noise formed in the return air cavity 2, the distance between the return air window 21 and the return air gathering port 22 can be controlled to avoid being too close.

[0089] Therefore, the distance between the return air window 21 and the return air collection port 22 is controlled to be 8 mm or above to take into account both ventilation smoothness and low disturbance noise.

[0090] On the other hand, the distance between the return air window 21 and the return air collection port 22 can be limited to 20 mm or less to reduce the space occupied by the return air cavity due to the large distance and to avoid insufficient air flow backflow. Therefore, the thickness of the return air cavity 2 can be generally 8 to 20 mm.

[0091] In some embodiments, the left and right widths of the drawer body 1 can be set to 400mm to 600mm, in the height direction, the height range of the return air window 21 can be set to 50 to 100mm, the thickness of the return air cavity 2 can be set to 8 to 20mm, and the specifications of the return air collection port 22 can be set to 20×70mm.

[0092] In some embodiments, a refrigeration device is also provided, comprising the above-mentioned drawer.
