Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, specifically a refrigerator that combines air heat exchange with direct cooling and cyclic control refrigeration for food preservation. Background Technology

[0002] Currently, in both domestic and international markets, traditional air-cooled refrigerators are commonly used. These refrigerators employ a single air-cooling technology and unit configuration. The refrigerator compartment is typically divided into two parts: a freezer compartment with a temperature setting of -18°C and a refrigerator compartment with a temperature setting of 4°C. People usually store fruits and vegetables, dairy products, tea, and alcoholic beverages in the refrigerator compartment (4°C) for preservation. However, because traditional air-cooling technology is used for preservation, its biggest advantages are rapid cooling, fast temperature reduction, and good cooling effect. However, due to the characteristics of air-cooling technology, fruits and vegetables, dairy products, tea, and traditional Chinese medicine stored in the refrigerator compartment are prone to continuous loss of moisture, nutrients, and protein, resulting in a continuous change in appearance. This leads to a short shelf life and a high risk of mold and rot, resulting in significant food loss and waste. If people consume these unhealthy products, it can lead to health problems and even endanger their lives. Under normal circumstances, fruits and vegetables stored in a traditional refrigerator at an ambient temperature of 4°C will last for about 5-10 days. Beyond this time, the quality of fruits and vegetables will change, and the moisture, nutrients, and proteins in them will continuously be lost, resulting in a change in appearance. The medicinal properties and activity of Chinese herbal medicines will also change, failing to achieve the desired medicinal effect.

[0003] However, existing refrigerator technologies still have the following problems in actual use:

[0004] 1. Simplified refrigeration design: Traditional air-cooled refrigerators typically have a simplified refrigeration design, using a single air-cooling refrigeration technology design and configuration;

[0005] 2. Fixed refrigeration temperature: The design temperature is fixed at 4 ℃. Placing fruits, vegetables, dairy products, and tea in a passive and fixed refrigeration temperature of 4 ℃ will not meet the requirements for the preservation temperature and humidity of fruits, vegetables, dairy products, and tea, nor will it meet the requirements for the preservation of cell activity of fruits, vegetables, dairy products, and tea.

[0006] 3. Temperature and humidity values ​​are controlled in a fixed and singular manner, without the use and implementation of dynamic temperature and temperature difference control management and real-time monitoring methods;

[0007] 4. The structural design is too simplistic, lacking the design and installation of air (oxygen) heat exchange equipment (intake pipe, intake fan, intake and exhaust pipes, exhaust fan and exhaust port) and control system;

[0008] 5. No negative ion membrane was designed or installed;

[0009] 6. No visual detectors or video surveillance systems and equipment were designed and installed;

[0010] 7. No carbon dioxide detector, humidifier, or dehumidifier were designed and installed;

[0011] 8. No video surveillance cameras or monitors (TV screens) were designed and installed for 0℃-10℃ monitoring.

[0012] 9. No capillary tube (copper tube) equipment was designed and installed;

[0013] 10. No dynamic temperature difference control system and control module were designed and installed;

[0014] 11. No WAF remote control power on / off and control module was designed and installed;

[0015] 12. No infrared antivirus equipment or control module was designed and installed;

[0016] To address the aforementioned issues, a refrigerator combining air heat exchange with direct cooling and circulating control refrigeration is provided for food preservation. Utility Model Content

[0017] The purpose of this utility model is to provide a refrigerator that combines air heat exchange with direct cooling and cyclic controlled refrigeration to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a refrigerator that combines air heat exchange with direct cooling and cyclic controlled refrigeration, comprising a refrigerator, an exhaust fan installed in the inner cavity of the refrigerator, a compressor installed in the inner cavity of the refrigerator, a condenser installed at the bottom of the inner cavity of the refrigerator, multiple graphene sheets installed in the inner cavity of the refrigerator, wheels installed at the bottom of the refrigerator, multiple shelves arranged sequentially from top to bottom in the inner cavity of the refrigerator, an exhaust vent installed on the rear side of the inner cavity of the refrigerator, a capillary tube fixedly embedded in the inner cavity of the side wall of the refrigerator, a controller installed on the refrigerator, and a monitoring component installed in the inner cavity of the refrigerator.

[0018] Preferably, the wheel is a self-locking swivel wheel.

[0019] Preferably, the monitoring component includes a first video sensor, an infrared disinfection sensor, a temperature and humidity sensor, a quantum sensor, a second video sensor, and a carbon dioxide sensor. The first video sensor is disposed at the front of the refrigerator, the infrared disinfection sensor is disposed in the inner cavity of the refrigerator, the temperature and humidity sensor is disposed in the inner cavity of the refrigerator, the quantum sensor is disposed in the inner cavity of the refrigerator, the second video sensor is disposed in the inner cavity of the refrigerator, and the carbon dioxide sensor is disposed in the inner cavity of the refrigerator.

[0020] Preferably, the refrigerator is equipped with a display and a controller at the front end.

[0021] Preferably, the refrigerator is provided with a display screen on its top.

[0022] Preferably, the refrigerator's inner cavity is provided with a negative ion membrane.

[0023] Preferably, the condenser is connected to a drying and filtering device via a pipe.

[0024] Preferably, the condenser is equipped with a cooling fan.

[0025] Preferably, the drying and filtering device is equipped with a throttling device, the other end of which is connected to the compressor, and the other end of the compressor is fixedly connected to the condenser.

[0026] Preferably, the compressor is equipped with an evaporator.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] This system employs a combination of multiple systems and modules, integrating a video area with a dedicated preservation area. It utilizes air (oxygen) heat exchange technology and a dynamic, multi-temperature, multi-temperature-difference, closed-loop, infinitely circulating refrigeration control design and method. The dynamic air (oxygen) heat exchange, combined with direct cooling and circulating refrigeration, maintains a preservation temperature range of 0℃-10℃. It can maintain the freshness of different fruits and vegetables, dairy products, tea, and pharmaceuticals in real time, based on their properties and characteristics, as well as their requirements for temperature, temperature difference, humidity, and environmental conditions. This technology places all fruits and vegetables, dairy products, tea, and pharmaceuticals in the same preservation space (freshness compartment), ensuring that they do not affect each other's preservation effect or cross-contamination of odors, effectively protecting the food products. This product effectively preserves the moisture, nutrients, and protein in fruits, vegetables, dairy products, tea, and pharmaceuticals, maintaining their original flavor and texture. It utilizes a differentiated design structure, dynamic temperature control, differentiated temperature difference control, diverse modular applications, precise and diversified product categorization and preservation, and visualized product monitoring. The design structure, equipment configuration, and preservation methods employ a closed-loop, multi-temperature, multi-difference, infinitely cyclical control system with dynamic refrigeration and preservation temperatures between 0℃ and 10℃. While the overall design and combined applications of the refrigeration unit are unified, the control systems operate independently. It achieves integration (overall refrigerator design, modular application), separation (all configured control modules and systems are independent and controlled separately), and video (the entire food refrigerator is equipped with a visual monitoring module and system for real-time video monitoring). It adopts an air (oxygen) heat exchange and ventilation circulation refrigeration control system, which implements a design configuration and control method that allows for ventilation every 12 hours for 20 minutes each time, and air (oxygen) heat exchange time nodes.

[0029] The system implements a circulating air (oxygen) hot and cold exchange mechanism, constantly exchanging harmful gases (carbon dioxide) inside the refrigerator through the refrigerator's exhaust vents. Simultaneously, fresh air (oxygen) from outside is introduced into the refrigerator, creating a continuous, large-scale circulation of fresh air (oxygen). This ensures sufficient fresh air (oxygen) to maintain the cell activity of food products stored inside, keeping them in an optimal dormant state and meeting the refrigerator's optimal temperature and humidity requirements. For fruits and vegetables, dairy products, and tea, dynamic, infinitely circulating temperature and temperature difference control, along with dynamic, time-based real-time air (oxygen) hot and cold exchange, is implemented to expel harmful gases from the refrigerator. Fresh air (oxygen) from outside the refrigerator is introduced into the refrigerator cabinet, effectively purifying and circulating the air. This allows the cells of fruits, vegetables, dairy products, and tea to maintain a suitable temperature and humidity for cell activity within this sealed, cold environment. This ensures sufficient fresh air (oxygen) for the cells of these products, putting them in a state of "dormancy." This dormancy preserves the original cell activity, moisture, nutrients, protein, appearance, and overall quality and safety of the products.

[0030] This effectively guarantees the quality of fruits and vegetables, dairy products, and tea, ensuring that moisture, nutrients, and protein are not lost and the appearance remains unchanged, ultimately achieving the goals of preservation, food safety, and health. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1 to 7This utility model provides a technical solution: a refrigerator combining air heat exchange with direct cooling and circulating control refrigeration, including a refrigerator 1. The refrigerator 1 has an exhaust fan 2 and a compressor 3 installed inside the refrigerator 1. The refrigerator 1 has a condenser 4 at the bottom of the refrigerator 1. The refrigerator 1 has multiple graphene sheets 5 inside the refrigerator 1. The refrigerator 1 has wheels 6 at the bottom of the refrigerator 1. The refrigerator 1 has multiple shelves 7 arranged from top to bottom inside the refrigerator 1. The refrigerator 1 has an exhaust vent 8 at the rear of the refrigerator 1. The refrigerator 1 has a capillary tube 9 fixedly embedded in the side wall of the refrigerator 1. The refrigerator 1 has a controller 11. The refrigerator 1 has a monitoring component installed inside the refrigerator 1. At a normal temperature of 25°C, the direct cooling unit starts to start refrigeration and at the same time starts the air (oxygen) heat exchange control system. The air (oxygen) heat exchange system starts to implement positive and negative pressure heat exchange ventilation in the refrigerator compartment, one is to input air (oxygen) and the other is to expel carbon dioxide and harmful gases inside the refrigerator 1. The air (oxygen) heat exchange system processes air (oxygen) input and carbon dioxide exhaust every 8 hours for 20 minutes each time. The operating timelines for air (oxygen) input and exhaust (thermal carbon dioxide) are: 0-8 hours for the first cycle; 8-16 hours for the second cycle; and 16-24 hours for the third cycle. This cycle repeats continuously. After refrigerator 1 completes the first, second, and third heat exchange cycles, its control system operates on a pre-designed control flow, time intervals, number of air exchanges, and timing intervals, continuously cycling through the heat exchange process to maintain fresh air (oxygen) within refrigerator 1. At a normal temperature of 25°C, the refrigerator 1 control system automatically activates the direct cooling compressor and begins cooling. When the direct cooling compressor 3 starts working and rapidly lowers the temperature at a rate of 0.42°C per minute, after 60 minutes, when the refrigerator compartment temperature drops from 25°C to 0°C, the refrigerator 1 control system automatically stops the direct cooling compressor 3. The system automatically starts the direct-cooling compressor 3 to begin cooling when the temperature in the refrigerator compartment of refrigerator 1 naturally rises from 0°C to the maximum temperature of 10°C after 30 minutes at an upward rate of 0.33°C per minute. When the temperature in the refrigerator compartment of refrigerator 1 rapidly decreases from the maximum temperature of 10°C to the minimum temperature of 0°C after 30 minutes, the system automatically stops the direct-cooling compressor 3 and simultaneously ceases cooling. This closed-loop, dynamic, temperature-differential, and infinitely cyclical cooling and preservation process is repeated.After refrigerator 1 completes the first, second, and third fixed temperature and time value workflow, the refrigerator 1 control system will implement infinite loop control of cooling according to the designed control process, temperature nodes, and time nodes to ensure that the temperature, humidity, and oxygen levels in refrigerator 1 achieve the purpose of freshness and preservation.
