Description

Technical Field

[0001] This utility model belongs to the field of refrigerator-related technical technology, and in particular relates to a freezing component and a refrigerator. Background Technology

[0002] The temperature of the freezer compartment in a T-type refrigerator is usually set at -18℃ or lower. When the freezer door is opened in a normal temperature environment, the user will clearly feel the cold air leaking out, causing discomfort to the legs or other body parts close to the freezer compartment due to the large temperature difference.

[0003] Currently, existing T-shaped refrigerators typically address the discomfort users experience when opening the freezer door through a programmed airflow control design within the freezer compartment. However, when the fan in the freezer compartment's airflow system stops, cold air still escapes through the gap between the door liner and the drawer front cover (with a distance ≥10mm), causing the drawer front cover surface temperature to be too low. While reducing the distance between the door liner and the drawer front cover can decrease cold air leakage, it hinders cold air circulation, thus affecting the uniformity of the freezer compartment temperature. Furthermore, because the drawer front cover is in direct contact with the low-temperature airflow from the airflow outlet, its temperature still cannot be effectively raised, failing to fundamentally solve the problem of user discomfort due to the low temperature when their body is near the drawer front cover. Utility Model Content

[0004] In view of this, it is necessary to provide a refrigeration component and refrigerator for solving the above-mentioned technical problems.

[0005] A freezing assembly for use in a refrigerator, the freezing assembly comprising:

[0006] The freezer enclosure is designed to form a freezer compartment.

[0007] A refrigeration air duct is installed on the refrigeration unit, and the refrigeration air duct has an air outlet that is connected to the refrigeration compartment;

[0008] A drawer is housed within the freezer compartment and is positioned corresponding to the air outlet. The drawer includes a drawer body and a front cover. The front cover is located on one side of the drawer body and connected to it. The front cover encloses an air supply channel. An air inlet is provided on the front cover, and the air supply channel can communicate with the corresponding air outlet through the air inlet. The front cover includes a drawer panel.

[0009] A heat insulation pad is provided corresponding to the drawer. The heat insulation pad is located in the air supply channel of the corresponding drawer. The heat insulation pad is located between the drawer panel and the drawer air inlet and faces the drawer panel. It is used to block the cold air introduced by the drawer air inlet from blowing towards the drawer panel.

[0010] Understandably, by setting up an air supply channel for circulating cold air into the drawer front cover and adding a heat insulation pad inside the air supply channel, the cold air can be blocked from blowing directly onto the drawer panel. This reduces the direct impact of cold air on the drawer panel, thereby lowering the temperature of the outer surface of the drawer panel and preventing it from becoming too cold. In this way, the problem of low temperature discomfort when the user's body is close to the drawer front cover is solved.

[0011] In one embodiment, the heat insulation pad is attached to the drawer panel and abuts against the drawer panel for sealing.

[0012] Understandably, attaching the heat insulation pad to the drawer front panel not only facilitates its installation inside the drawer front cover but also ensures that the heat insulation pad effectively blocks cold air from entering the drawer front cover.

[0013] In one embodiment, the front cover of the drawer is also provided with a drawer air outlet, which is located below the drawer air inlet in the height direction of the refrigerator and is connected to the air supply channel.

[0014] A drawer sealing strip is provided on the outer peripheral surface of the drawer front cover. The drawer sealing strip is located on the outside of the drawer air inlet and the drawer air outlet, and the drawer sealing strip can enclose and seal the drawer front cover in the drawer located in the freezer compartment.

[0015] It is understandable that drawer seals are used to seal the cold air circulation in the drawer, thus ensuring that the circulating cold air does not pass over the outer side of the drawer panel, thereby further reducing the temperature of the outer surface of the drawer front cover.

[0016] In one embodiment, the number of drawers is configured to be multiple, and the multiple drawers are arranged sequentially along the height direction of the refrigerator.

[0017] In one embodiment, the area of ​​the air inlet of each drawer is greater than twice the area of ​​the corresponding air outlet; and the area of ​​the air inlet of each drawer is greater than the area of ​​the air outlet.

[0018] It is understandable that by setting the ventilation area as described above, the speed at which cold air enters the air supply duct can be reduced, and the cold air can be made to flow out of the air supply duct quickly.

[0019] In one embodiment, the area of ​​the plurality of air outlets decreases sequentially from top to bottom along the height direction of the refrigerator;

[0020] Furthermore, the area of ​​the air outlet of the drawer is greater than or equal to the sum of the areas of the corresponding air outlet and the air outlets above it.

[0021] It is understandable that by setting the ventilation area as described above, the uniformity of the temperature inside the freezer room can be improved.

[0022] In one embodiment, the freezing assembly further includes a freezing door with a door seal, and the freezing door is able to abut and seal against the freezing cabinet via the door seal.

[0023] It is understandable that using door seals to achieve a tight seal between the freezer door and the freezer compartment ensures good sealing of the freezer compartment, thus maintaining a good temperature and reducing the workload of the corresponding compressor and other refrigeration components in the freezer assembly, thereby reducing energy consumption.

[0024] In one embodiment, the drawer panel is partially recessed toward the drawer body and has a handle.

[0025] The handle portion is U-shaped.

[0026] Understandably, designing the recessed handle on the drawer panel as a U-shape increases the area of ​​the handle, making it easier for users to reach inside and pull the drawer out of the freezer, thus improving the user experience.

[0027] In one embodiment, the drawer body is slidably connected to the freezer body via a slide rail mechanism;

[0028] The slide rail mechanism is equipped with a push-spring component, which can drive the drawer to pop out of the freezer body a preset distance.

[0029] Understandably, using a slide rail mechanism with a push-out component to automatically pop the drawer out of the freezer allows the user to grab and pull it out, thus improving the user experience.

[0030] In addition, this application also provides a refrigerator, including the freezing components described above.

[0031] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0032] The refrigeration unit and refrigerator for which this application seeks protection have an air supply channel for circulating cold air to the drawer inside the front cover of the drawer, and an insulation pad is added inside the air supply channel of the front cover of the drawer. The insulation pad is used to block the cold air from blowing onto the drawer panel of the front cover of the drawer. This reduces the direct blowing of cold air onto the drawer panel, thereby lowering the temperature of the outer surface of the drawer panel and preventing overcooling. In this way, the problem of low temperature discomfort when the user's body is close to the front cover of the drawer is solved. Attached Figure Description

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] The refrigeration assembly 100 claimed in this application specifically refers to the freezer compartment structure of a T-type refrigerator. Of course, the aforementioned refrigeration assembly can also be applied to single-door refrigerators, three-door refrigerators, etc., which will not be elaborated upon here.

[0045] like Figures 1 to 6As shown, the refrigeration assembly 100 provided in this application includes a freezer body 10, a freezer duct 20, a drawer 30, and a heat insulation pad 40; the freezer body 10 encloses a freezer compartment 11; the freezer duct 20 is installed on the freezer body 10 and has an air outlet 21 that communicates with the freezer compartment 11; the drawer 30 is housed in the freezer compartment 11 and is correspondingly arranged with respect to the air outlet 21; the drawer 30 includes a drawer body 31 and a drawer front cover 32, the drawer front cover 32 is disposed on one side of the drawer body 31 and connected to the drawer body 31, and the drawer front cover 32 encloses the freezer compartment 11. An air supply channel 301 is formed, and a drawer air inlet 302 is provided on the drawer front cover 32. The air supply channel 301 can communicate with the corresponding air outlet 21 through the drawer air inlet 302. The drawer front cover 32 includes a drawer panel 321. A heat insulation pad 40 is correspondingly disposed with the drawer 30. The heat insulation pad 40 is disposed in the air supply channel 301 of the corresponding drawer 30, and is positioned between the drawer panel 321 and the drawer air inlet 302, facing the drawer panel 321, to prevent the cold air introduced by the drawer air inlet 302 from blowing onto the drawer panel 321. Here, the drawer panel 321 specifically refers to the side of the drawer front cover 32 away from the freezing air channel 20, and is positioned so that the user's body is close to the drawer panel 321 when the user pulls out the drawer 30. It should be noted that other structural components and working principles in the freezing assembly 100 of this application can adopt existing conventional methods, and will not be elaborated here.

[0046] As can be seen from the above, the refrigeration component 100 of this application has an air supply channel 301 for supplying cold air circulation to the drawer 30 inside the drawer front cover 32, and a heat insulation pad 40 is added inside the air supply channel 301 of the drawer front cover 32. The heat insulation pad 40 is used to block the cold air from blowing onto the drawer panel 321 of the drawer front cover 32. This reduces the direct blowing of cold air onto the drawer panel 321, thereby reducing the temperature of the outer surface of the drawer panel 321 and avoiding overcooling. In this way, the problem of low temperature discomfort when the user's body parts are close to the drawer panel 321 is solved.

[0047] like Figures 1 to 3 As shown, in this application, the number of drawers 30 is configured to be multiple, and the multiple drawers 30 are arranged sequentially along the height direction of the refrigerator. Here, the number of drawers 30 is configured to be three. It can be understood that in other embodiments, the number of drawers 30 may also be one, two, four, or even more, which will not be elaborated here.

[0048] like Figure 1 , Figure 5As shown, in one embodiment, a drawer air outlet 303 is also provided on the drawer front cover 32. The drawer air outlet 303 is located below the drawer air inlet 302 in the height direction of the refrigerator and is connected to the air supply channel 301. That is, the cold air circulation of the drawer 30 can pass through the air supply channel 301 of the drawer front cover 32 from top to bottom. Here, in this embodiment, the drawer air outlet 303 of the upper drawer 30 is located directly above the drawer air inlet 302 of the lower drawer 30, and the drawer air outlet 303 of the upper drawer 30 can discharge cold air towards the drawer air inlet 302 of the lower drawer 30.

[0049] like Figure 2 As shown, in one embodiment, the area of ​​the drawer air inlet 302 in each drawer 30 is more than twice the area of ​​the corresponding air outlet 21; and the area of ​​the drawer air inlet 302 in each drawer 30 is greater than the area of ​​the drawer air outlet 303. This reduces the speed at which cold air enters the air supply channel 301 and allows the cold air to flow out of the air supply channel 301 quickly. It should be noted that when cold air enters the drawer air inlet 302 from the air outlet 21 of the refrigeration duct 20 through the drawer body 31, the pressure of the cold air is lower and the air speed is slower due to the larger area of ​​the cold air flow. However, when the cold air passes through the air supply channel 301 and is discharged from the drawer air outlet 303, the pressure of the cold air increases and the air speed increases due to the smaller area of ​​the drawer air outlet 303, thus facilitating the rapid flow of cold air.

[0050] like Figure 6 As shown, in this embodiment, the area of ​​the multiple air outlets 21 decreases sequentially from top to bottom along the height of the refrigerator; and the area of ​​the drawer air outlet 303 in the drawer 30 is greater than or equal to the sum of the areas of the corresponding air outlet 21 and the air outlets 21 above it, so that the cold air discharged from all the air outlets 21 of the freezer air duct 20 can be returned through the return air vent 22 at the bottom of the freezer air duct 20, and promote the circulation of cold air in each drawer 30, thereby improving the uniformity of the temperature in the freezer compartment. Here, the sum of the areas of the corresponding air outlet 21 and the air outlets 21 above it specifically refers to the sum of the areas of the corresponding air outlet 21 and the areas of all the air outlets 21 located above it.

[0051] like Figure 4As shown, in one embodiment, the drawer panel 321 is partially recessed towards the drawer body 31 and forms a handle 3211; wherein, the handle 3211 is U-shaped, which increases the area of ​​the handle 3211, thereby making it easier for the user to reach into the handle 3211 and pull the drawer 30 out of the freezer body 10, thus improving the user experience. Here, the handle 3211 is located at the top of the drawer panel 321, a design that is more ergonomic.

[0052] like Figure 2 As shown, in one embodiment, the drawer body 31 is slidably connected to the freezer compartment 10 via a slide rail mechanism 310. The slide rail mechanism 310 is equipped with a push-spring component (not shown), which can push the drawer 30 out of the freezer compartment 10 a preset distance. In other words, the user can press the drawer panel 321 to activate the push-spring component. When the user releases the drawer panel 321, the drawer 30 automatically springs out a preset distance under the force of the push-spring component, allowing the user to grab and pull out the drawer 30, thus improving the user experience. It should be noted that the specific structure and working principle of the slide rail mechanism 310 and the push-spring component can adopt existing conventional methods, and will not be elaborated upon here.

[0053] like Figure 1 , Figure 5 As shown, in one embodiment, the heat insulation pad 40 is attached to and seals against the drawer panel 321. Specifically, the heat insulation pad 40 can be pasted onto the drawer panel 321. This not only facilitates the installation of the heat insulation pad 40 inside the drawer front cover 32, but also ensures that the heat insulation pad 40 effectively blocks cold air from entering the drawer front cover 32. Here, the heat insulation pad 40 can be specifically configured as heat insulation foam, silicone pad, etc.

[0054] like Figure 1 , Figures 3 to 5 As shown, in one embodiment, a drawer sealing strip 50 is provided on the outer peripheral surface of the drawer front cover 32. The drawer sealing strip 50 is located on the outside of the drawer air inlet 302 and the drawer air outlet 303. The drawer sealing strip 50 can enclose and seal the drawer front cover 32 located in the freezer compartment 11, thus ensuring that the circulating cold air of the drawer 30 does not pass through the outer side of the drawer panel 321, thereby further reducing the temperature of the outer surface of the drawer panel 321. Here, the drawer sealing strip 50 is configured as a hollow structure, which facilitates the deformation of the drawer sealing strip 50 under pressure.

[0055] like Figure 1As shown, in one embodiment, the refrigeration assembly 100 further includes a refrigeration door 60, which is provided with a door seal 61. The refrigeration door 60 can be sealed to the refrigeration cabinet 10 through the door seal 61, so that the refrigeration compartment 11 has good sealing performance and good temperature retention. This reduces the workload of the corresponding compressor and other refrigeration components in the refrigeration assembly 100, and has the effect of reducing energy consumption.

[0056] In addition, this application also provides a refrigerator, including the aforementioned freezing component 100.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
