[0002] Freezers, as a common household appliance, can be divided into direct-cooling freezers and air-cooling freezers based on their cooling method. Air-cooling freezers enclose the finned evaporator in an open space, using a fan to force air convection circulation, bringing the cooling energy generated by the evaporator into the storage space.

[0024] The inventors discovered that in some existing refrigeration equipment, a cold film layer mode is used to avoid manual defrosting. In the air-cooled mode, the finned evaporator is enclosed in an open space, and the cooling energy generated by the finned evaporator is carried into the storage space by forced air convection through a fan. However, in some existing horizontal refrigeration equipment, the placement and arrangement of the finned evaporator are unreasonable, resulting in long air ducts that affect heat exchange efficiency and increase equipment power consumption.

[0025] In view of this, this embodiment provides a refrigeration device that can improve and reduce the loss of evaporator cooling capacity, thereby reducing energy consumption. The solution provided in this embodiment will be described in detail below.

[0026] Please see Figure 1 , Figure 1 The refrigeration device provided in this embodiment may include a refrigerator, freezer or other equipment used for low-temperature storage. The refrigeration device is mainly composed of a first compartment 100 with an upward opening, a second compartment 200, a heat insulation component 300 and an evaporator component 400.

[0027] The refrigeration equipment provided in this embodiment is a horizontal design. The first chamber 100 and the second chamber 200, with their openings facing upwards, are storage spaces for items, allowing for direct access to and removal of items from above. For example, the refrigeration equipment provided in this embodiment can be a horizontal dual-temperature zone refrigeration equipment.

[0028] A heat insulation component 300 is vertically disposed between the first chamber 100 and the second chamber 200 to separate the two chambers and prevent heat transfer between them. In the refrigeration equipment provided in this embodiment, the required refrigeration temperatures in the first chamber 100 and the second chamber 200 are different. Heat transfer may affect the temperature stability of each chamber, thereby affecting the storage effect of the items. The presence of the heat insulation component 300 can effectively reduce unnecessary heat transfer between the first chamber 100 and the second chamber 200, allowing the first chamber 100 and the second chamber 200 to maintain relatively independent temperature environments, meeting the storage temperature requirements of different items.

[0029] The evaporator assembly 400 is disposed within the first chamber 100 and abuts against the side wall of the first chamber 100 facing the second chamber 200. The evaporator assembly 400 includes an evaporator cavity 410, a finned evaporator 420, and a cooling fan 430. The evaporator cavity 410 is a relatively enclosed space, providing a stable operating environment for the finned evaporator 420 and the cooling fan 430. The finned evaporator 420 is used to exchange heat with air during the refrigeration process, absorbing heat from the air to lower its temperature. The cooling fan 430 is used to accelerate airflow, enabling the air to exchange heat with the finned evaporator 420 more quickly, thus improving refrigeration efficiency.

[0030] Optionally, the refrigeration equipment provided in this embodiment further includes a compressor 720 connected to the finned evaporator 420. The compressor 720 is used to compress low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure refrigerant gas. The compressor 720 is connected to other components of the refrigeration system through pipes to form a closed refrigeration cycle. When the refrigeration equipment starts cooling, the compressor 720 begins to work, continuously drawing in low-temperature, low-pressure refrigerant gas returning from the finned evaporator 420 and compressing it.

[0031] The finned evaporator 420 consists of multiple fins 422 and pipes 421. The fins 422 are located on the surface of the pipes 421 to increase the heat exchange area and improve heat exchange efficiency. High-temperature, high-pressure refrigerant gas is discharged from the compressor 720, cooled by the condenser, and becomes a medium-temperature, high-pressure liquid. It then passes through a throttling device to reduce its pressure before entering the finned evaporator 420. Inside the finned evaporator 420, the refrigerant liquid evaporates into a low-temperature, low-pressure gas, thereby absorbing heat from the surrounding environment. A cooling fan 430 is used to transport the low-temperature air around the finned evaporator 420 to the first compartment 100 and / or the second compartment 200.

[0032] Specifically, the evaporator cavity 410 includes a first heat exchange component communicating with the first chamber 100 and a second heat exchange component penetrating the insulation component 300 and communicating with the second chamber 200. The first heat exchange component allows air circulation between the evaporator cavity 410 and the first chamber 100. When the cooling fan 430 is working, the air cooled by the finned evaporator 420 is delivered to the first chamber 100 through the first heat exchange component, thereby cooling the first chamber 100. The second heat exchange component penetrates the insulation component 300 and communicates with the second chamber 200, similarly enabling air circulation between the evaporator cavity 410 and the second chamber 200, allowing cooled air to also be delivered to the second chamber 200, providing cooling to the second chamber 200.

[0033] Based on the above design, in the refrigeration equipment provided in this embodiment, by setting the evaporator between the two chambers of the horizontal refrigeration equipment, the length of the air duct can be effectively reduced. That is, the length of the gas transmission path from the finned evaporator 420 to the cold air fan 430 to the first chamber 100 and / or the second chamber 200 is reduced, thereby reducing the loss of cooling capacity, improving the refrigeration effect, reducing energy consumption, and reducing production and installation costs.

[0034] Furthermore, the refrigeration equipment provided in this embodiment adopts air-cooled refrigeration, which can achieve frost-free refrigeration and eliminates the need for manual defrosting by the user.

[0035] In some possible implementations, the first heat exchange component includes a first air outlet 511 and a first air return outlet 512. In the vertical direction, the first air outlet 511 is located above the first air return outlet 512, and the first air return outlet 512 is located at the bottom of the first compartment 100. The first air outlet 511 and the first air return outlet 512 cooperate to form a reasonable circulation path within the first compartment 100.

[0036] When the cooling fan 430 operates, it delivers air cooled by the finned evaporator 420 into the first chamber 100 through the first air outlet 511. Since the first air outlet 511 is located at the top, the cooling air diffuses downwards, allowing for thorough heat exchange with the items in the first chamber 100. The hot air rises and then flows back to the evaporator cavity 410 through the first return air inlet 512 located at the bottom, where it is cooled again. This helps improve the temperature uniformity within the first chamber 100, ensuring effective cooling.

[0037] The second heat exchange assembly includes a second air outlet 521 and a second air return outlet 522. In the vertical direction, the second air outlet 521 is located above the second air return outlet 522, and the second air return outlet 522 is located at the bottom of the second chamber 200. The second air outlet 521 and the second air return outlet 522 cooperate to form a reasonable circulation path within the second chamber 200.

[0038] Optionally, please see Figure 2 The second air outlet 521 and the second air return outlet 522 pass through the side wall of the first cavity 100, the heat insulation component 300 and the side wall of the second cavity 200 in sequence, thereby communicating with the interior of the second cavity 200.

[0039] When the cooling fan 430 operates, it delivers the air cooled by the finned evaporator 420 into the second chamber 200 through the second air outlet 521. Since the second air outlet 521 is located at the top, the cooling air diffuses downwards, allowing for thorough heat exchange with the items inside the second chamber 200. The hot air rises and then flows back to the evaporator cavity 410 through the second return air inlet 522 located at the bottom, where it is cooled again. This helps improve the temperature uniformity within the second chamber 200, ensuring effective cooling.

[0040] In actual operation, when the refrigeration equipment starts working, air flows in the first chamber 100 and the second chamber 200 according to the aforementioned circulation path. In the first chamber 100, cold air enters from the first air outlet 511, diffuses downwards, absorbs heat upon contact with the objects, and becomes hot air. The hot air rises to the top and flows back to the evaporator cavity 410 through the first return air inlet 512. In the second chamber 200, cold air enters from the second air outlet 521, similarly diffuses downwards, and the hot air rises and flows back to the evaporator cavity 410 through the second return air inlet 522.

[0041] This allows the refrigeration equipment to form an effective air circulation within the first chamber 100 and the second chamber 200, improving refrigeration efficiency and temperature uniformity. This air circulation method ensures that all parts of each chamber receive sufficient cooling, preventing excessive temperature differences.

[0042] In some possible implementations, the insulation component 300 includes an insulating foam layer with good insulation properties, effectively preventing heat transfer between the first compartment 100 and the second compartment 200. When the required cooling temperatures for the first compartment 100 and the second compartment 200 differ, the insulating foam layer can reduce unnecessary heat exchange between the two compartments, thereby better stabilizing the temperature within both compartments.

[0043] For example, the first chamber 100 and the second chamber 200 can be two relatively independent cavities with a gap between them. The heat insulation component 300 is disposed in the gap between the two cavities and fills the gap.

[0044] In addition, the soft texture of the insulating foam layer allows it to fit well with various components, reducing gaps and further improving the insulation effect. Furthermore, the insulating foam layer also has some sound insulation properties, which can reduce the noise generated by refrigeration equipment during operation.

[0045] Specifically, the heat insulation component 300 can be made of various materials, such as cyclopentane foam, polyurethane foam, polystyrene foam, etc. In this embodiment, the heat insulation foam layer can be provided with an opening that penetrates the heat insulation foam layer in the horizontal direction. The opening is connected to the evaporator cavity 410 to form the second air outlet 521 and the second return air outlet 522.

[0046] In some possible implementations, the evaporator cavity 410 includes a cavity housing 411 that covers the surface of the insulating foam layer facing the first chamber 100 to form the evaporator cavity 410.

[0047] Optionally, the cavity shell 411 typically possesses a certain degree of strength and sealing performance, protecting the components within the evaporator cavity 410 from external environmental influences. The cavity shell 411 prevents dust, moisture, and other impurities from entering the evaporator cavity 410, ensuring the normal operation of the finned evaporator 420 and the cooling fan 430. Simultaneously, the sealing performance of the cavity shell 411 reduces cold air leakage and improves refrigeration efficiency.

[0048] For example, the cavity shell 411 can be snapped onto one side of a relatively flat insulating foam layer. On the side facing the first chamber 100, the cavity shell 411 can have an opening connecting the first chamber 100 and the evaporator cavity 410, thus forming a first air outlet 511 and a first air return outlet 512. On the side facing the second chamber 200, the insulating foam layer can have an opening penetrating horizontally through the insulating foam layer, which connects to the evaporator cavity 410, thus forming a second air outlet 521 and a second air return outlet 522.

[0049] Based on the above design, in this embodiment, the cavity shell 411 is covered on the surface of the heat insulation foam layer facing the first chamber 100, so that the heat exchange efficiency between the evaporator cavity 410 and the first chamber 100 is better, ensuring the cooling efficiency of the first chamber 100. The second chamber 200 is also separated from the evaporator cavity 410 by a foam layer, which can prevent the evaporator cavity 410 from directly exchanging heat with the second chamber 200 and avoid the temperature in the second chamber 200 being too low.

[0050] In some possible implementations, the cooling temperature of the first compartment 100 is lower than that of the second compartment 200.

[0051] For example, the first compartment 100 can be used to store items that require lower temperatures, such as frozen foods, meat, and seafood. These items typically need to be stored at lower temperatures to maintain their freshness and quality. Lower temperatures can inhibit the growth and reproduction of microorganisms, extending the shelf life of the items. The second compartment 200 can be used to store items that require relatively higher temperatures, such as fruits, vegetables, and beverages. These items can maintain better taste and nutritional components at appropriate refrigeration temperatures.

[0052] When the refrigeration equipment is operating, by adjusting parameters such as the refrigerant flow rate and the operating power of the compressor 720, the first compartment 100 reaches a lower cooling temperature, while the second compartment 200 reaches a relatively higher cooling temperature. During this process, the evaporator assembly 400 provides cooling capacity to the first compartment 100 and the second compartment 200 respectively through the first heat exchange assembly and the second heat exchange assembly. Because the first compartment 100 has a lower cooling temperature, it requires more cooling capacity to maintain its temperature, which may increase the cooling capacity supplied by the evaporator assembly 400 to the first compartment 100.

[0053] In practical applications, users can place different items in different compartments according to their needs. For example, users can put frozen meat in the first compartment 100 and fresh fruits and vegetables in the second compartment 200. In this way, the refrigeration equipment can provide a suitable storage temperature environment for different items, meeting the diverse needs of users.

[0054] In some possible implementations, the refrigeration equipment also includes an electrically operated damper 600 located on the air supply path between the cooling fan 430 and the second air outlet 521. That is, the air supply path from the cooling fan 430 to the second air outlet 521 needs to pass through the electrically operated damper 600 first.

[0055] The electric damper 600 is a device whose opening and closing degree can be controlled by electricity. When cooling is required for the second chamber 200, the electric damper 600 opens, and the air cooler 430 delivers air cooled by the finned evaporator 420 through the electric damper 600 to the second air outlet 521, and then into the second chamber 200. By controlling the opening degree of the electric damper 600, the airflow into the second chamber 200 can be adjusted. For example, when the temperature of the second chamber 200 is high, the opening degree of the electric damper 600 can be appropriately increased to increase the airflow and accelerate the cooling speed; when the temperature of the second chamber 200 is close to the set value, the opening degree of the electric damper 600 can be decreased to reduce the airflow and maintain a stable temperature.

[0056] In actual operation, refrigeration equipment is usually equipped with a temperature sensor to monitor the temperature of the second compartment 200. When the temperature sensor detects that the temperature of the second compartment 200 is higher than the set value, the control system will send a signal to open the electric damper 600 to a larger angle, increasing the airflow. As the temperature of the second compartment 200 decreases, when the temperature approaches the set value, the control system will gradually reduce the opening degree of the electric damper 600 until the temperature stabilizes near the set value.

[0057] This design, with the electric damper 600, allows the refrigeration equipment to more flexibly control the temperature of the second chamber 200, improving the equipment's temperature control accuracy and energy efficiency. Precise control of the airflow prevents over-cooling and reduces energy waste. Simultaneously, it better meets users' personalized temperature needs for the second chamber 200.

[0058] Please see Figure 3 When the first chamber 100 has a cooling request while the second chamber 200 does not, the compressor 720 starts running, the cold air fan 430 starts running, and the electric damper 600 is in the closed state. The air in the first chamber 100 begins to circulate, obtains cooling through the finned evaporator 420, and is sent out through the first air outlet 511 by the cold air fan 430. After exchanging heat with the items in the first chamber 100, it becomes a relatively hot air flow and flows back to the evaporator cavity 410 from the first return air outlet 512 to circulate again until the cooling request of the first chamber 100 ends.

[0059] Please see Figure 4 When the second chamber 200 has a cooling request, regardless of whether the first chamber 100 has a cooling request, the compressor 720 starts running, the air cooler 430 starts running, and the electric damper 600 is in the open state. Cool air is obtained from the finned evaporator 420 and simultaneously delivered to the outside through the second air outlet 521 and the first air outlet 511 by the air cooler 430. The air exchange occurs in the second chamber 200 and the first chamber 100 respectively, and then returns to the evaporator cavity 410 through the second return air outlet 522 to recirculate until the cooling request of the second chamber 200 ends and the electric damper 600 closes. At this time, if the first chamber 100 still has a cooling request, the compressor 720 and the air cooler 430 continue to run until the cooling request of the first chamber 100 ends.

[0060] In some possible implementations, the bottom of the second chamber 200 is higher than the bottom of the first chamber 100 in the vertical direction, and the refrigeration equipment also includes a compressor cavity 710 located below the second chamber 200 and a compressor 720 located within the compressor cavity 710.

[0061] The compressor chamber 710 provides a relatively independent working space for the compressor 720, which can reduce the impact of noise and vibration generated by the compressor 720 during operation on other components. At the same time, the compressor chamber 710 can also play a certain protective role, preventing external dust, moisture and other impurities from entering the compressor 720, thus extending the service life of the compressor 720.

[0062] In this embodiment, the compressor cavity 710 is positioned below the second chamber 200. This arrangement serves two purposes: firstly, it maximizes the use of space, making the equipment more compact. By strategically arranging the positions of components within a limited space, the space utilization rate of the equipment is improved, reducing the floor space required. Secondly, since the compressor 720 generates heat during operation, placing it below the second chamber 200 prevents this heat from affecting the temperature of the first chamber 100. The temperature inside the first chamber 100 is typically lower, while the temperature inside the second chamber 200 is typically higher. Isolating the compressor 720 from the first chamber 100 and placing it on one side of the second chamber 200 reduces the impact of the compressor 720's heat on the first chamber 100, ensuring the temperature stability of the first chamber 100.

[0063] Thus, the rational placement of the compressor chamber 710 and compressor 720 not only improves the space utilization of the refrigeration equipment but also ensures the temperature stability of the second chamber 200 and the operational reliability of the equipment. Through this structural design, the refrigeration equipment can operate more efficiently and stably.

[0064] In some possible implementations, the second return air vent 522 is located at the same height as at least part of the finned evaporator 420 in the vertical direction.

[0065] Specifically, since the compressor 720 chamber is located below the second chamber 200, the bottom of the second chamber 200 is raised, and correspondingly, the position of the second return air vent 522 is also raised. In this case, the second return air vent 522 and at least part of the finned evaporator 420 are at the same horizontal height.

[0066] Thus, when the second return air vent 522 is at the same height as at least part of the finned evaporator 420, the hot air returning from the second chamber 200 can exchange heat more directly with the finned evaporator 420. During its ascent, the hot air does not need to undergo excessive turns and flow to directly reach the surface of the finned evaporator 420 and make full contact with it. This improves the efficiency of heat exchange, allowing the hot air to cool down more quickly before being transported back to the second chamber 200 through the second air outlet 521, achieving a more efficient refrigeration cycle.

[0067] In actual operation, when the cooling fan 430 is working, it delivers cooled air to the second chamber 200 through the second air outlet 521. The air exchanges heat with the items in the second chamber 200, increasing its temperature and becoming hot air. As the hot air rises, and since the second return air outlet 522 is at the same height as at least part of the finned evaporator 420, the hot air can quickly enter the evaporator cavity 410 through the second return air outlet 522 and exchange heat with the finned evaporator 420. During this process, the heat of the hot air is absorbed by the finned evaporator 420, lowering its temperature, and then it is again delivered to the second chamber 200 by the cooling fan 430 to continue the refrigeration cycle.

[0068] This improves the heat exchange efficiency and cooling performance of the refrigeration equipment. In this way, energy loss during the refrigeration process is reduced, energy utilization efficiency is improved, and the temperature of the second room (200°C) can be lowered more quickly to meet the user's cooling needs.

[0069] In some possible implementations, the refrigeration device also includes a first door 810 located on the opening side of the first compartment 100 and capable of closing the opening of the first compartment 100, and a second door 820 located on the opening side of the second compartment 200 and capable of closing the opening of the second compartment 200.

[0070] The main function of the first door 810 and the second door 820 is to seal the openings of the first chamber 100 and the second chamber 200, reducing the entry of external heat. When the doors are closed, they form a relatively enclosed space, preventing hot air from entering the cavity and maintaining a stable internal temperature. At the same time, the doors also prevent dust, moisture, and other impurities from entering the cavity, protecting the items inside.

[0071] In practical use, users open the corresponding door when they need to retrieve or place items. After completing the task, the door should be closed promptly to minimize heat loss. The door is typically sealed with sealing materials, such as rubber sealing strips, to improve its sealing performance. This further reduces heat transfer and enhances the energy efficiency of the refrigeration equipment.

[0072] In some possible implementations, the refrigeration equipment also includes a defrost drain pipe located outside the first compartment 100 and the second compartment 200 and communicating with the evaporator cavity 410. The defrost drain pipe is located outside the first compartment 100 and the second compartment 200 to prevent defrost water from affecting the items inside the cavity. If defrost water flows directly into the first compartment 100 or the second compartment 200, it may cause the items to become damp or damaged, affecting their storage quality.

[0073] When the refrigeration equipment undergoes defrosting, the frost on the surface of the finned evaporator 420 is typically melted into water through heating or other methods. This defrosting water collects at the bottom of the evaporator cavity 410 and is then drained from the equipment through a defrosting drain pipe connected to the evaporator cavity 410. The defrosting drain pipe generally has a certain slope to ensure that the defrosting water flows out smoothly and avoids water accumulation.

[0074] In actual operation, defrosting is typically performed at regular intervals to ensure the cooling efficiency of the finned evaporator 420. When defrosting begins, defrost water gradually forms and flows into the bottom of the evaporator cavity 410, then flows out of the device along the defrost drain pipe. To prevent the defrost water from freezing and clogging the pipe during drainage, the defrost drain pipe may be wrapped with insulation material or a heating device may be installed around the pipe.

[0075] This design, with its defrost drain pipe, ensures the proper functioning of the refrigeration equipment's defrosting process, prevents defrost water from affecting items inside the cavity, and improves the equipment's reliability and stability. Timely drainage of defrost water ensures the finned evaporator 420 always maintains optimal operating condition, enhancing the overall performance of the refrigeration equipment.

[0076] In summary, this application provides a refrigeration device that, by placing the evaporator between two compartments of a horizontal refrigeration device, can effectively reduce the length of the air duct, reduce cold loss, improve the refrigeration effect, reduce energy consumption, and reduce production and installation costs.

[0077] In addition, the functional modules in the various embodiments of this application can be integrated together to form an independent part, or each module can exist independently, or two or more modules can be integrated to form an independent part.
