Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a quick-cooling drawer and a refrigerator. Background Art

[0002] In modern home life, as one of the core appliances in the kitchen, the importance of household refrigerators is self-evident. In order to store various ingredients more efficiently and keep them fresh and tasty, household refrigerators are generally designed with drawer structures in the freezer and refrigerator compartments. These drawers are not only convenient for users to store ingredients by category, but also can isolate odors to a certain extent, improving the preservation of ingredients.

[0003] In order to further improve the refrigeration performance of the refrigerator, especially to meet the needs of users for quick freezing of food, air vents are usually set on the surface of the drawer. These air vents are closely connected with the quick freezing air duct inside the refrigerator to form an efficient cold air circulation system. When the refrigerator starts the quick freezing function, the cold air will quickly flow into the drawer through these air vents, accelerating the freezing process of the food and ensuring that the food can quickly reach the ideal freezing state.

[0004] However, in actual use, due to improper stacking of ingredients or the different sizes and shapes of the ingredients themselves, the air vents are easily blocked. Once the air vents are blocked, the circulation of cold air will be hindered and cannot be evenly distributed to every corner of the drawer, thus affecting the freezing effect of the ingredients, causing some ingredients to be frozen unevenly or frozen for too long, and may also increase the energy consumption of the refrigerator and shorten its service life.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0031] In some technologies, the air outlet of the refrigerator is easily blocked due to improper stacking of food, thereby affecting the freezing effect of the food and causing uneven freezing of some food. In order to solve this technical problem, the present application provides a quick cooling drawer and a refrigerator. The structures of the quick cooling drawer and the refrigerator are described below:

[0032] For example, in modern home life, as one of the core appliances in the kitchen, the importance of household refrigerators is self-evident. In order to store various types of food more efficiently and maintain their freshness and taste, drawer structures are generally designed in the freezing and refrigerating compartments of household refrigerators. These drawers are not only convenient for users to store food in categories, but also can isolate odors to a certain extent and improve the preservation effect of food.

[0033] In order to further improve the refrigeration performance of the refrigerator, especially to meet the needs of users for quick freezing of food, air vents are usually set on the surface of the drawer. These air vents are closely connected with the quick freezing air duct inside the refrigerator to form an efficient cold air circulation system. When the refrigerator starts the quick freezing function, the cold air will quickly flow into the drawer through these air vents, accelerating the freezing process of the food and ensuring that the food can quickly reach the ideal freezing state.

[0034] However, in actual use, due to improper stacking of ingredients or the different sizes and shapes of the ingredients themselves, the air vents are easily blocked. Once the air vents are blocked, the circulation of cold air will be hindered and cannot be evenly distributed to every corner of the drawer, thus affecting the freezing effect of the ingredients, causing some ingredients to be frozen unevenly or frozen for too long, and may also increase the energy consumption of the refrigerator and shorten its service life.

[0035] like Figure 1 As shown, it is a structural schematic diagram of the medium-speed cold drawer in this application.

[0036] In view of the above problems, the first aspect of the present application provides a rapid cooling drawer, comprising:

[0037] A drawer body 1 is provided with a handle portion 11 and a storage cavity 2 for storing items; a first rapid cooling air duct 3 is provided at the bottom of the storage cavity 2, a second rapid cooling air duct 4 is provided between the storage cavity 2 and the handle portion 11, and the first rapid cooling air duct 3 and the second rapid cooling air duct 4 are connected; the storage cavity 2 can be set to any one of aluminum, copper, iron metal or plastic materials; preferably, the storage cavity 2 is set to aluminum.

[0038] A first air inlet 12 is provided on a side of the drawer body 1 away from the handle portion 11, and the first air inlet 12 is communicated with the first rapid cooling air duct 3; the first air inlet 12 is connected to the refrigeration equipment in the refrigerator, and the first air inlet 12 is used to transmit cold air to the first rapid cooling air duct 3, thereby providing cold air to the accommodating cavity 2 and providing a low-temperature environment for the food in the accommodating cavity 2.

[0039] A plurality of first protrusions 21 and first through holes 22 are provided on one side of the accommodating cavity 2 close to the handle portion 11; the provision of the first protrusions 21 can prevent the food placed in the accommodating cavity 2 from clogging the first through holes 22, and the first through holes 22 are located between the gaps of the first protrusions 21. When food is placed in the accommodating cavity 2, the provision of the first protrusions 21 can prevent the food from clogging the first through holes 22, thereby avoiding the problem of obstruction of the circulation of cold air.

[0040] Exemplarily, the first protrusions 21 are distributed on the side wall surface of the accommodating cavity 2 near the handle portion 11 in a specific arrangement and shape. From the appearance, the first protrusions 21 are protruding structures on the wall surface, and they maintain a certain distance from each other, forming a series of staggered gaps. The first through holes 22 are arranged between the gaps formed by the first protrusions 21. Each first through hole 22 can provide cold air to the accommodating cavity 2. Among them, the size and shape of the first through hole 22 are also precisely calculated, which is necessary to ensure that the cold air can pass smoothly, and to consider the overall structural strength and stability of the accommodating cavity 2.

[0041] For example, when the user places food in the accommodating cavity 2, the food may be randomly stacked in the accommodating cavity 2 due to its own shape, texture and other factors. If there is no structural setting of the first protrusion 21, the food placed in the accommodating cavity 2 may block the surface where the first through hole 22 is located. Once the first through hole 22 is blocked, the cold air cannot flow normally in the accommodating cavity 2, which will cause uneven temperature distribution in the accommodating cavity 2. Food in some areas (food far from the first through hole 22) may not be fully cooled, affecting the preservation effect of the food.

[0042] However, due to the existence of the first protrusion 21, when food is placed in the accommodating cavity 2, the first protrusion 21 will have a certain obstructive effect on the food, preventing the food from being directly stacked on the first through hole 22. When the food encounters the first protrusion 21, it will be forced to change its stacking method, thereby forming a certain space between the gaps of the first protrusion 21, so that the first through hole 22 can always remain unobstructed. In this way, cold air can smoothly flow through the first through hole 22 in the accommodating cavity 2, ensuring that the temperature of each area in the accommodating cavity 2 is uniform, avoiding the problem of cold air circulation being obstructed due to food blocking the first through hole 22, thereby effectively improving the quality and effect of food preservation.

[0043] A plurality of first air outlets 41 are provided on the side of the second rapid cooling air duct 4 close to the accommodating chamber 2, and the positions of the first air outlets 41 correspond to the positions of the first through holes 22, so that the second rapid cooling air duct 4 is connected to the accommodating chamber 2. A plurality of first air outlets 41 are provided on the side of the second rapid cooling air duct 4 close to the accommodating chamber 2, and the first air outlets 41 and the first through holes 22 are located in the same horizontal direction, that is, the positions of the first air outlets 41 correspond to the positions of the first through holes 22, and the cold air enters through the first air inlet 12, is transmitted to the second rapid cooling air duct 4 through the first rapid cooling air duct 3, and then is transmitted to the accommodating chamber 2 through the first air outlet 41, so as to realize the rapid cooling function of the accommodating chamber 2.

[0044] In this embodiment, a plurality of second through holes 23 are provided at the bottom of the accommodating cavity 2; a plurality of second air outlets 31 are provided on the side of the first rapid cooling air duct 3 close to the accommodating cavity 2, and the positions of the second air outlets 31 correspond to the positions of the second through holes 23, so that the first rapid cooling air duct 3 is connected to the accommodating cavity 2.

[0045] It is understandable that, in the actual operation of the refrigeration equipment, when a plurality of first air outlets 41 are provided only on the side of the second speed cold air duct 4 close to the accommodating chamber 2, some potential problems will be faced. Since the food itself has different shapes and sizes, coupled with the uncertainty of the placement method of the user during use, it is very likely that the food placed on the side close to the second speed cold air duct 4 will completely block the first air outlet 41 due to its large size or inappropriate placement. Once the first air outlet 41 is completely blocked, the cold air blown out from the second speed cold air duct 4 cannot be blown normally to the area in the accommodating chamber 2 away from the second speed cold air duct 4. In this case, the cold air will be unevenly distributed inside the accommodating chamber 2. The food close to the side of the second speed cold air duct 4 can be directly blown by the cold air, and the temperature can drop rapidly, while the food far away from the side of the second speed cold air duct 4 cannot be exposed to enough cold air, resulting in uneven cooling of the food in the entire accommodating chamber 2.

[0046] For example, uneven cooling will greatly reduce the efficiency of food cooling. Food that could have been cooled quickly in a short time will now take longer to reach the ideal temperature, which not only increases the energy consumption of the refrigerator, but also reduces the efficiency of the equipment. On the other hand, uneven cooling will also affect the cooling effect of food. If the temperature of food in different areas is too different, it may cause the quality of the food to decline or even deteriorate.

[0047] In order to effectively solve the above problems, the present application is provided with a plurality of second through holes 23 at the bottom of the accommodating chamber 2, which are evenly distributed on the bottom wall of the accommodating chamber 2. At the same time, a plurality of second air outlets 31 are provided on the side of the first rapid cooling air duct 3 close to the accommodating chamber 2, and the second air outlets 31 correspond to the second through holes 23. When the refrigeration equipment starts to run, the cold air in the first rapid cooling air duct 3 will be blown out through the second air outlet 31, and then enter the interior of the accommodating chamber 2 through the second through hole 23 at the bottom of the accommodating chamber 2. In this way, cold air will also be continuously blown out from the bottom of the accommodating chamber 2, forming a cold air flow path from the bottom to the top. This cold air blown out from the bottom cooperates with the cold air blown out from the first air outlet 41 of the second rapid cooling air duct 4 to form a more uniform and comprehensive cold air circulation system.

[0048] Based on the above structure, no matter where the food is placed in the accommodating chamber 2, it can be evenly blown by the cold air. Even if the food near the second rapid cooling air channel 4 blocks the first air outlet 41, the second through hole 23 at the bottom of the accommodating chamber 2 can ensure that enough cold air enters, thereby ensuring that the cold air is evenly distributed inside the accommodating chamber 2. In this way, the efficiency and effect of rapid cooling of food are effectively improved, which can not only save energy but also better ensure the quality and freshness of food.

[0049] In this embodiment, a plurality of second protrusions 24 are disposed at the bottom of the accommodating cavity 2. In order to further prevent the second air outlet 31 from being blocked, the present application provides a plurality of second protrusions 24 at the bottom of the accommodating cavity 2.

[0050] Exemplarily, the present application arranges a plurality of second protrusions 24 at the bottom of the accommodating cavity 2; the arrangement of the second protrusions 24 can prevent the food placed in the accommodating cavity 2 from clogging the second through hole 23, and the second through hole 23 is located between the gaps of the second protrusions 24. When food is placed in the accommodating cavity 2, the arrangement of the second protrusions 24 can prevent the food from clogging the second through hole 23, thereby avoiding the problem of obstruction of the circulation of cold air.

[0051] like Figure 2 , which is a schematic structural diagram of the first protrusion / second protrusion and the first through hole / second through hole in one embodiment of the present application.

[0052] In this embodiment, the first protrusion 21 and the second protrusion 24 are configured to be hemispherical. By configuring the first protrusion 21 and the second protrusion 24 to be hemispherical, it is possible to further prevent food from blocking the air outlet between the first protrusion 21 or the second protrusion 24.

[0053] For example, from the perspective of physical structural characteristics, the hemispherical shape has a unique curved surface morphology. Compared with sharp edges or flat structures, the surface of the hemispherical shape is smoother and rounder. When the food is placed in the accommodating cavity, the food will come into contact with the first protrusion 21 and the second protrusion 24 under the action of its own gravity and possible shaking, squeezing and other factors. If it is a sharp edge or a flat structure, the food can easily get stuck at the edge or gap of these structures, and then it may accumulate and block the air outlet located therebetween. However, when the food contacts the hemispherical protrusion, it will slide down along its smooth curved surface instead of being stuck like encountering sharp edges, thereby greatly reducing the possibility of food accumulation on the protrusion.

[0054] Secondly, when food applies pressure to the hemispherical protrusion, the hemispherical curved surface can evenly disperse this pressure. In contrast, when a sharp-edged structure is subjected to pressure, the stress will be concentrated at the corners, causing the food to deform or break. In addition, the hemispherical protrusion helps to guide the airflow. When the cold air flows out of the air outlet, the hemispherical protrusion can act like a guide plate to allow the airflow to pass more smoothly. Even if some food is close to the air outlet, the hemispherical protrusion can change the direction of the airflow, so that the cold air is more evenly distributed in the accommodating cavity 2.

[0055] For example, in actual use scenarios, there are many types of food, various shapes, and various ways of placement. For example, some irregularly shaped fruits and vegetables, or frozen foods with wrinkled packaging, etc., are easily in complex contact with the protruding structure after being placed in the accommodating cavity. The hemispherical first protrusion 21 and the second protrusion 24 can guide the airflow well by virtue of their smooth and rounded surfaces, and can effectively prevent food from accumulating on their surfaces. Even if the food moves to a certain extent in the accommodating cavity, the hemispherical protrusion can reduce the friction between the food and the protrusion, making it less likely for the food to stay at the air outlet position, thereby further preventing the food from blocking the air outlet between the first protrusion 21 or the second protrusion 24, and ensuring that the food in the accommodating cavity 2 is evenly cooled.

[0056] like Figure 3 , which is a schematic structural diagram of the first protrusion / second protrusion and the first through hole / second through hole in another embodiment of the present application.

[0057] In this embodiment, the first protrusion 21 and the second protrusion 24 are arranged in a strip shape. Compared with the first protrusion 21 and the second protrusion 24 being arranged in a semicircle, the first protrusion 21 and the second protrusion 24 in a strip shape can reduce the difficulty of manufacturing the accommodating chamber 2 for the manufacturer while not reducing the cooling effect.

[0058] In this embodiment, the first through hole 22 is disposed between adjacent first protrusions 21, and the first protrusion 21 is disposed between adjacent first through holes 22; the second through hole 23 is disposed between adjacent second protrusions 24, and the second protrusion 24 is disposed between adjacent second through holes 23. The first protrusions 21 and the first through holes 22 are alternately arranged on one side of the accommodating chamber 2 close to the second speed cooling air duct 4; the second through holes 23 and the second protrusions 24 are alternately arranged on the bottom of the accommodating chamber 2.

[0059] In this embodiment, the above structure has the following advantages:

[0060] 1. Optimize air flow distribution and improve cooling efficiency

[0061] Uniform exhaust: The alternating arrangement of the first protrusion 21 and the second protrusion 24 and the first through hole 22 and the second through hole 23 can make the cold air more evenly distributed to all corners of the accommodating cavity when passing through the through holes. For example, when the cold air blows out from the first through hole 22, the first protrusion 21 will guide the airflow to change direction to avoid the airflow being directly concentrated in one area, so that the food in the entire accommodating cavity can be blown by the cold air more evenly, thereby improving the refrigeration efficiency. Increased airflow disturbance: The alternating arrangement of protrusions and through holes increases the disturbance of the airflow. This disturbance can break the dead corners of the airflow that may exist in the accommodating cavity, allowing the cold air to better contact the food and accelerate the heat exchange process of the food.

[0062] 2. Ensure smooth ventilation

[0063] Guide food distribution: The alternating arrangement of protrusions and through holes can also guide the distribution of food in the accommodating cavity. Under the action of gravity and airflow, food tends to fill the space between the protrusions instead of accumulating in the through holes. In this way, the through holes can always remain unobstructed, ensuring the normal circulation of cold air, so that the refrigeration equipment can work continuously and stably.

[0064] 3. Enhance structural strength and improve the stability of the accommodating cavity

[0065] Dispersing stress: The first protrusion 21 and the second protrusion 24 are provided to help disperse the stress on the wall of the receiving cavity. When food is placed in the receiving cavity 2, the receiving cavity 2 is subjected to a certain pressure. The protrusions can disperse the stress to the surrounding area to avoid the pressure being concentrated at a certain point, thereby improving the bearing capacity of the wall of the receiving cavity 2 and reducing the risk of deformation or rupture of the wall due to pressure concentration.

[0066] Increase structural stability: The alternating structure of protrusions and through holes increases the overall structural stability of the accommodating cavity and improves the accommodating cavity's ability to resist deformation. Even when subjected to external impact or vibration, the accommodating cavity can maintain a relatively stable shape, ensuring the normal operation of the refrigeration equipment.

[0067] In this embodiment, the first air outlet 41 is provided on the side of the accommodating chamber 2 close to the handle 11, and the second air outlet 31 is provided at the bottom. Although such a setting can realize the delivery of cold air to a certain extent, there is a problem of insufficient cold air support near the top of the side of the accommodating chamber 2 away from the handle 11. When the refrigeration device is turned on, cold air is generated from the refrigeration system and delivered to the vicinity of the accommodating chamber 2 through the quick cooling channel. The first air outlet 41 and the second air outlet 31 will blow cold air into the accommodating chamber 2 respectively, but due to the lack of a special cold air delivery setting for the top of the side of the accommodating chamber 2 away from the handle 11, this area often becomes a weak zone for cold air distribution. If it is in this state for a long time, the degree of cooling of food in different areas of the accommodating chamber 2 will be significantly different. The food close to the air outlet can be cooled quickly, while the food at the top of the side away from the handle 11 may be cooled slowly because it does not get enough cold air, which will not only affect the preservation effect of the food, but also may cause the food to deteriorate.

[0068] In order to solve the above problems, the present application sets a second air inlet 25 on the side of the top of the accommodating chamber 2 away from the handle portion 11. When the refrigeration device is running, the cold air enters the accommodating chamber 2 through the second air inlet 25. Since its entry position is located at the top of the side of the accommodating chamber 2 away from the handle portion 11, this area can be directly cooled. After the cold air enters the accommodating chamber 2, a more uniform air flow distribution will be formed in the accommodating chamber 2. It will cooperate with the cold air blown out from the first air outlet 41 and the second air outlet 31 to form a three-dimensional cold air circulation system. Through the above structure, the cold air can evenly cover every corner of the accommodating chamber 2. Whether it is the side close to the handle portion 11 or the top of the side away from the handle portion 11, sufficient cold air can be supplied. In this way, no matter where the food in the accommodating chamber 2 is, it can be blown by uniform cold air, thereby ensuring that the food can be evenly cooled in all directions. This not only improves the preservation quality of food and prolongs the preservation time of food, but also significantly improves the refrigeration effect of the refrigeration device.

[0069] In this embodiment, the handle 11, the accommodating chamber 2, the first rapid cooling air duct 3, and the second rapid cooling air duct 4 are connected by a fixing member. Through the setting of the fixing member, the handle 11, the accommodating chamber 2, the first rapid cooling air duct 3, and the second rapid cooling air duct 4 are integrated. In daily use, the rapid cooling drawer will be frequently pulled out and pushed in, and the handle 11 will be subjected to repeated tension and pressure. If there is no reliable connection of the fixing member, the handle 11 may loosen due to long-term stress, or even separate from the accommodating chamber 2, resulting in the rapid cooling drawer being unable to be used normally. The presence of the fixing member makes the connection between the handle 11 and the accommodating chamber 2 more stable, can withstand greater external forces, and is not prone to loosening or damage. The integrated structure also enhances the overall strength and stability of the rapid cooling drawer. When facing external impact or vibration, the rapid cooling drawer can better maintain its shape and structure, and is not prone to deformation or damage. This not only extends the service life of the rapid cooling drawer, but also improves its reliability and safety, and improves the user experience.

[0070] In this embodiment, a plurality of pulleys 5 are relatively arranged at the bottom of the drawer body 1. When the user wants to take out the quick cooling drawer from the refrigeration device, he only needs to gently hold the drawer handle and apply a small horizontal pulling force, and the pulley 5 will roll smoothly on the contact surface with the internal guide rail or base of the refrigeration device. Since the pulley converts sliding friction into rolling friction, the friction force is greatly reduced, and the user can easily and smoothly pull out the drawer body 1 without spending a lot of effort. Similarly, when pushing the drawer back to the refrigeration device, the pulley 5 can also ensure that the drawer slides in smoothly, and the entire operation process is easy and comfortable, which greatly improves the user experience.

[0071] For example, if the pulley 5 is not provided, direct friction will occur between the bottom of the drawer body 1 and the contact surface inside the refrigeration device. During the frequent pushing and pulling process, the friction will cause the coating or material at the bottom of the drawer body 1 to gradually wear out, resulting in scratches, paint peeling, etc., which will not only affect the appearance of the drawer, but also make the bottom of the drawer rough, further exacerbating the friction. At the same time, the guide rails or base inside the refrigeration device will also be deformed or damaged due to long-term friction. The provision of the pulley 5 effectively avoids the wear and tear caused by friction between the drawer body 1 and the refrigeration device, thereby extending the service life of the drawer body 1 and the refrigeration device.

[0072] A second aspect of the present application provides a refrigerator, comprising:

[0073] A quick cooling drawer as described in any of the above embodiments.

[0074] It is worth noting that the effects of the above refrigerator embodiment can refer to the effects of the above quick cooling drawer embodiment, which will not be described in detail here.

[0075] The present application provides a quick cooling drawer, which is applied to an air-cooled refrigerator. The quick cooling drawer is arranged in the refrigerator compartment, freezer compartment or temperature-changing compartment of the air-cooled refrigerator. The refrigerator is provided with an air duct and an air outlet connected to the compartment and the drawer. The drawer is movably accommodated in the freezer compartment of the air-cooled refrigerator. A protruding structure and a through hole are arranged at the bottom of the accommodating cavity 2 and on the side close to the handle portion 11. A quick cooling air duct is arranged between the bottom of the accommodating cavity 2 and the drawer body 1, and between the accommodating cavity 2 and the handle portion 11. The quick cooling air duct transmits cold air into the through hole. The arrangement of the protruding structure can prevent the through hole from obstructing the transmission of cold air into the accommodating cavity 2 when the food is placed in the accommodating cavity 2, so that the food in the accommodating cavity 2 can achieve a quick cooling effect.

[0076] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application.
