Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, and particularly relates to a single-unit dual-temperature freezer. Background Art

[0002] A freezer, also known as a refrigerator or a freezer cabinet, is an electrical appliance used to store food, beverages, or other items that need to be preserved at a low temperature. It mainly works through a refrigeration system to lower the temperature inside the cabinet to a suitable level for preserving these items, preventing food spoilage, bacterial growth, or keeping beverages cool. The working principle of a freezer is mainly based on a refrigeration cycle, including key components such as a compressor, a condenser, an expansion valve, and an evaporator. The compressor compresses the refrigerant into a high-temperature and high-pressure gas, which then dissipates heat and cools down through the condenser, becoming a high-pressure liquid. After the high-pressure liquid is throttled and depressurized by the expansion valve, it enters the evaporator, absorbs heat in the evaporator, and evaporates into a low-temperature and low-pressure gas, thereby achieving the refrigeration effect.

[0003] However, most freezers on the current market often use a single refrigeration device to regulate the temperature of the entire freezer space. When it is necessary to simultaneously achieve two different temperature environments of refrigeration and freezing, the traditional method is to configure two independent refrigeration devices. The parallel operation of the two refrigeration devices will significantly increase energy consumption, occupy more space, and at the same time, since each refrigeration device needs to independently reach the set temperature, the overall cooling speed is relatively slow, affecting the use efficiency. Summary of the Utility Model

[0030] Such as Figures 1 - 7As shown in the figure, a single-unit double-temperature freezer in an embodiment of the present utility model includes a cabinet body 1, a refrigeration unit 2, and a circulation structure 3. A partition plate 11 is arranged inside the cabinet body 1, and the partition plate 11 divides the cabinet body 1 into a refrigerating chamber 12 and a freezing chamber 13; the refrigeration unit 2 is arranged at one end of the cabinet body 1 close to the freezing chamber 13; the circulation structure 3 is arranged on the partition plate 11. An air inlet 31 and a first air return port 32 are arranged on one side of the circulation structure 3 close to the freezing chamber 13, and an air outlet 33 and a second air return port 34 are arranged on one side of the circulation structure 3 close to the refrigerating chamber 12. The air inlet 31 is communicated with the air outlet 33, and the first air return port 32 is communicated with the second air return port 34. By arranging the cabinet body 1, its internal space is divided into two independent areas by the partition plate 11, allowing users to store food in a suitable temperature environment according to different food storage requirements; by arranging the refrigeration unit 2, it can quickly respond to the cooling requirements of the freezing chamber 13; by arranging the circulation structure 3, it allows air to flow between the refrigerating chamber 12 and the freezing chamber 13, and maintains different temperatures in the two areas through the cooling effect of the refrigeration unit 2; an air inlet 31 and an air outlet 33 are arranged on one side of the circulation structure 3 close to the freezing chamber 13. The air inlet 31 allows cold air to enter the circulation structure 3, and the air outlet 33 sends the cooled cold air into the refrigerating chamber 12. The hot air in the refrigerating chamber 12 can reach the first air return port 32 through the second air return port 34, enter the freezing chamber 13, mix with the cold air in the freezing chamber 13 or be cooled separately by the refrigeration unit 2, and then return to the refrigerating chamber 12 through the first air return port 32, forming an air circulation in the refrigerating chamber 12.

[0031] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The circulation structure 3 includes an air inlet plate 35, a blower 36, an air outlet plate 37 and a wind deflector 38. The air inlet plate 35 is fixedly connected to one side of the partition plate 11 close to the freezer compartment 13, the air outlet plate 37 is fixedly connected to one side of the partition plate 11 close to the refrigerating compartment 12, the blower 36 is fixedly connected to the air outlet plate 37, and the wind deflector 38 is arranged on the side of the air inlet plate 35 close to the blower 36. The wind deflector 38 divides the air inlet plate 35 into an air inlet area 351 and a return air area 352, effectively preventing the direct mixing of cold air and hot air and improving the accuracy of temperature control; The air inlet 31 and the first return air inlet 32 are arranged on the air inlet plate 35, the air outlet 33 and the second return air inlet 34 are arranged on the air outlet plate 37. The air inlet 31 is communicated with the air outlet 33 through the air inlet area 351, and the first return air inlet 32 is communicated with the second return air inlet 34 through the return air area 352. The air inlet plate 35 is fixedly connected to one side of the partition plate 11 close to the freezer compartment 13, so that the air inlet plate 35 can directly contact the cold air released from the freezer compartment 13 or the air cooled by the refrigeration unit 2. The air inlet 31 is arranged on the air inlet plate 35 to allow this cold air to enter the circulation structure 3. When the blower 36 operates, it will generate a strong air flow, suck in the cold air introduced by the air inlet plate 35 and discharge it through the air outlet 33 of the air outlet plate 37; At the same time, the first return air inlet 32 is also arranged on the air inlet plate 35 to return part of the air that has passed through the refrigerating compartment 12 and has been heated to the circulation structure 3 so that it can be re-cooled and then sent back to the refrigerating compartment 12 or the freezer compartment 13 to form an air circulation; The air outlet 33 is arranged on the air outlet plate, so that the cold air accelerated and cooled by the blower 36 can directly blow to the refrigerating compartment 12, thereby realizing the rapid adjustment of the temperature in the refrigerating compartment 12. At the same time, the second return air inlet 34 is also arranged on the air outlet plate to return the air that has been heated in the refrigerating compartment 12 to the circulation structure 3 to maintain a constant temperature in the refrigerating compartment 12. This embodiment utilizes the combination of the air inlet plate, the blower 36 and the air outlet plate to realize the air circulation and temperature adjustment between the refrigerating compartment 12 and the freezer compartment 13. By controlling the rotation speed of the blower 36 and adjusting the sizes of the air inlet 31, the air outlet 33 and the return air inlets, the temperatures in the refrigerating compartment 12 and the freezer compartment 13 can be accurately controlled to meet the storage requirements of different items.

[0032] The air flow path is as follows: Air inlet path: Enter the air inlet area 351 through the air inlet 31, and then driven by the blower 36, the cold air is discharged through the air outlet 33 and sent to the refrigerating compartment 12 for cooling; Return air path: The hot air (or the heated air) in the refrigerating compartment 12 enters the return air area 352 through the second return air inlet 34 and returns to the freezer compartment 13 through the first return air inlet 32.

[0033] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The air inlet 31 is provided in the middle of the bottom of the air inlet plate 35, which can more effectively capture the cold air from the bottom of the freezer compartment 13. Since cold air is usually heavier than hot air, they will naturally sink and accumulate at the bottom of the refrigerator, which can ensure that the cold air is efficiently sucked into the circulation system and then accelerated by the fan 36 and distributed to the refrigerating compartment 12 and the freezer compartment 13.

[0034] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The first air return opening 32 is provided on both sides of the air inlet plate 35. By setting the air return opening on both sides of the air inlet plate 35, the air that has passed through the refrigerating compartment 12 or the freezer compartment 13 and may have warmed up can be more effectively guided back into the circulation system for re-cooling, which helps to maintain the temperature stability inside the refrigerator. It can make the air form a more complex flow pattern inside the refrigerator, which helps to reduce the temperature gradient and ensure that the temperature in each corner can reach the set value.

[0035] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The air outlet 33 is provided in the middle of the air outlet plate 37, which can make the air outlet direction of the fan 36 more stable and reduce the noise and vibration generated by the air flow disorder.

[0036] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The second air return opening 34 is provided at the top of the air outlet plate 37. In this embodiment, the top of the air outlet plate 37 is set as an open structure, and the open part of the air outlet plate 37 is the entire first air return opening 32, which can enable the warmed-up air to flow back into the circulation system of the refrigerator more smoothly. The recirculated hot air can be mixed with the newly entered cold air and then cooled again by the refrigeration unit 2, thereby forming a closed-loop air circulation system, which helps to enhance the intensity and efficiency of the air circulation and improve the overall cooling performance of the refrigerator.

[0037] As a preferred embodiment of the present utility model, it may further have the following additional technical features: A third air return opening 39 is provided at the bottom of the air outlet plate 37. The third air return opening 39 is communicated with the first air return opening 32 to form a more complex and efficient air circulation path, which helps to increase the air flow speed and coverage range inside the refrigerator, so that more hot air can be recovered in time and re-enter the refrigeration cycle, thereby improving the cooling efficiency of the entire refrigerator. Since the hot air will naturally rise inside the refrigerator while the cold air sinks, setting the third air return opening 39 at the bottom of the air outlet plate 37 can more effectively recover the sinking cold air or the hot air that has not been fully cooled. After these airs enter the circulation system through the third air return opening 39, they will also be cooled by the refrigeration unit 2.

[0038] As a preferred embodiment of the present utility model, it may further have the following additional technical features: The air outlet plate 37 includes a main board 371, a first side plate 372, and a second side plate 373. One end of the main board 371 is fixedly connected to the first side plate 372, and the end of the main board 371 away from the first side plate 372 is fixedly connected to the second side plate 373. The first side plate 372 and the second side plate 373 are respectively fixedly connected to the partition plate 11. The second air return opening 34 is provided on the first side plate 372 and the second side plate 373, and the third air return opening 39 is provided at the bottom of the first side plate 372 and the second side plate 373, so that the air outlet plate 37 can form a relatively closed structure with multiple openings, facilitating the flow and circulation of air. The second air return opening 34 is provided on the first side plate 372 and the second side plate 373, thereby collecting the hot air inside the freezer more widely. The third air return opening 39 is provided at the bottom of the first side plate 372 and the second side plate 373, further enhancing the efficiency of air circulation. The air outlet plate 37 not only guides the outflow of cold air but also realizes the recovery and re-cooling of hot air through the second air return opening 34 and the third air return opening 39, helping to reduce the temperature gradient inside the freezer and improve the uniformity of temperature distribution.

[0039] In this embodiment, the temperature of the freezer compartment 13 is -22°C to -18°C, and the temperature of the refrigerating compartment 12 is 2°C to 8°C.

[0040] The working principle of the single-unit dual-temperature freezer of this embodiment is as follows: The refrigeration unit 2 operates, first reducing the temperature of the air near the freezer compartment 13. The air inlet 31 captures the cold air from the bottom of the freezer compartment 13. When the temperature of the refrigerating compartment 12 needs to be adjusted, the fan 36 starts, generating a strong air current, sucking in the cold air introduced by the air inlet plate 35 and accelerating it through its interior. The accelerated cold air is directly blown towards the refrigerating compartment 12 through the air outlet 33 in the middle of the air outlet plate 37, realizing the rapid adjustment of the temperature inside the refrigerating compartment 12. The hot air inside the refrigerating compartment 12 flows back to the first air return opening 32 through the second air return opening 34 provided at the top of the air outlet plate 37. The additional third air return opening 39 is located at the bottom of the first side plate 372 and the second side plate 373 of the air outlet plate 37, further recovering the cold air or the hot air that has not been fully cooled and has accumulated at the bottom of the freezer due to natural sinking. These hot air are mixed with the cold air introduced from the freezer compartment 13 or are separately re-cooled by the refrigeration unit 2, and then the fan 36 discharges the cooled air into the refrigerating compartment 12, thus realizing a cycle process.

[0041] The single-unit dual-temperature freezer of this embodiment has a reasonable structural design and is convenient to use. For other devices with similar usage requirements, this structure can also be adopted. In this embodiment, the single-unit dual-temperature freezer can reduce unnecessary energy consumption, improve the overall energy efficiency ratio of the freezer, increase the storage space of the freezer, and effectively improve the usage efficiency.
