In some implementations, the refrigeration system may be a refrigerated circulation system consisting of a compressor, condenser, throttling device and evaporator 27, etc. The evaporator 27 is configured to directly or indirectly provide cold energy within the storage compartment. The refrigeration system itself of the refrigerated freezer is well known to those skilled in the art and will not be repeated here. Additionally, a cooling chamber may be installed within the box 20, and specifically, may be installed on the rear side of the third storage chamber. The inside of the cooling chamber is used to accommodate the evaporator (27). The number of cooling chambers and evaporators 27 may be one or more. When there is one evaporator 27, cold energy can be provided to all storage chambers, and when there are multiple evaporators 27, each evaporator 27 can provide cold energy to one storage chamber.

In some embodiments of the present invention, as shown in FIG. 2, at least one shelf 40 is installed in the first storage compartment, and the first storage compartment is divided into at least two storage spaces 21 by the shelf 40. Divide it into The refrigerated freezer further includes an air flow path system and a level generating device (50). The air flow path system has at least two vents, at least two first vents 81, and an on-off control device. Each vent communicates with the cooling chamber and one storage space 21, and each first vent 81 communicates with one storage space 21 and the cooling chamber. The on-off control device 60 is configured to control the airflow from the cooling chamber to flow toward one or more of the at least two vents, so that all or part of the airflow flows toward the corresponding storage space 21. Specifically, the on-off control device 60 may cause the airflow from the cooling chamber to flow only toward one storage space 21, or may cause the airflow to flow toward two or more storage spaces 21 at the same time. . That is, it can be used to control the ventilation of each storage space 21.

The level generating device 50 is configured to generate at least two sets of level commands. Each level command set includes a plurality of level commands, and each level command set controls one storage space 21 to correspond. Each level command includes control information for positioning the corresponding storage space 21 within one target temperature or one target temperature range, so that the refrigeration freezer turns on and off the control device 60 according to each level command. control, and furthermore, to control the temperature within the corresponding storage space (21).

For example, in some embodiments, the level generating device 50 includes at least two display control panels installed on the inner wall of each storage space 21 . Each display control panel is configured to receive a signal and generate a level command of one level command set. Additionally, each display control panel is configured to display the type of article recommended for storage in the corresponding storage space 21 . Each display control panel may be installed adjacent to a corresponding storage space (21). Additionally, each display control panel can input information using sliding, clicking, etc. methods.

Additionally, the display icon may be directly a text. That is, all information related to the corresponding level command can be displayed on the screen.

Since the above embodiment is provided with an air flow path system and a level generating device 50, independent areas of the refrigerator refrigeration compartment are divided and temperatures of 2°C, 5°C, and 10°C (low, medium, and high) are determined in the separated areas of each floor. It can be implemented to independently control various levels of temperature. Therefore, users can adjust the temperature of each layer of the refrigerator according to their needs and habits. Through balanced control of temperature and humidity, an optimal storage environment for various foods is realized, and users can choose the optimal storage space. Provide guidance on placing food correctly. Before this application, the refrigerator had the same temperature on each floor, but because the optimal storage temperature and humidity were different for each food, users were unable to carelessly put some instant foods and tropical fruits with low storage temperatures in the refrigerator. The temperature was too low to be eaten right away, so users could not place it outside, and tropical fruits had to be stored between 8 and 10 degrees Celsius to maintain optimal preservation time, so they could not be placed in the refrigerator. Food put in the refrigerator was also not in the optimal temperature range, so the food spoiled quickly, causing serious waste. An embodiment of the present invention allows food to be stored in an optimal storage space by freely adjusting the temperature of each layer of the refrigerator according to the user's needs, and guides the user to correctly place food in the optimal storage space. Each storage space (21) has its own independent air discharge and independent ventilation functions, and each storage space (21) implements multi-stage temperature changes and can be freely switched.

Furthermore, if the number of level commands in each level command set is relatively large, a new level can be used when the target temperature in the storage space changes by 1 degree Celsius. This is also called stepless level control. For example, there may be 11 levels between 0°C and 10°C, so each storage space 21 can adjust its temperature arbitrarily between 0°C and 10°C. Of course, you can also set only three levels between 0℃ and 10℃: 0℃ ice temperature range, 4℃ golden range, and 10℃ tropical fruit range.

Additionally, each air outlet communicates with one storage space 21 through a corresponding air outlet. In some specific embodiments, it is the same as the shunt blowing device in CN104879994A, CN106196840A, etc. Rotation of the adjustment member may be driven by a motor and gear transmission mechanism. For example, if there are three storage spaces (21) and three air outlets, there are 7 or 8 options, such as fully open, fully closed, one air outlet open (3 ways), and two of them open (3 ways). Blowing mode can be implemented.

The three first vents 81 and the second vents 82 are sequentially installed along the vertical direction. Each first vent 81 is installed on one lower side of the corresponding storage space 21. The second vent 82 is installed on one lower side of the drawer space 22. The at least two air outlets include a first air outlet, and a second air outlet and a third air outlet installed on both sides of the first air outlet. The first air outlet faces upward.

There are four air vents communicating with the storage space 21 at the uppermost side, the first air vent, and are installed on both sides of the upper part and the middle part of the storage space 21, respectively. There are two second air vents communicating with the intermediate storage space 21, and each is installed on both sides of the upper part of the storage space 21. There is only one air vent communicating with the storage space 21 at the lowest side, the third air vent, and is installed on one upper side of the storage space 21.

Furthermore, as shown in FIGS. 6 and 7, the blowing assembly 70 includes a first blowing air duct 71, a second blowing air duct 72, a crossover air duct 73, and a third blowing air duct. An air duct 74 is installed. The lower end of the first blowing air duct 71 communicates with the first air outlet, and the upper part communicates with the four first blowing ports. The second blowing air duct 72 is installed on one side of the first blowing air duct 71, the lower end communicates with the second air outlet, and the upper part communicates with one second blowing port and the crossover air duct 73. The crossover air duct 73 crosses the first blowing air duct 71 and communicates with the second blowing port. The third blowing air duct 74 is installed on the other side of the first blowing air duct 71, and the lower end communicates with the third air outlet, and the upper end communicates with the third blowing port. Preferably, both the third blowing air duct 74 and the third blowing port are located on one side of the first blowing air duct 71, which is far from the ventilation assembly 80. As shown in FIG. 8, a ventilation air duct is installed within the ventilation assembly 80, and each first ventilation opening 81 communicates with the ventilation air duct.

In the embodiment of the present invention, as shown in FIGS. 4 and 5, the cold air coming out of the cooling chamber is delivered into the blower assembly 70, and the blower assembly 70 is equipped with an air volume distributor, that is, a shunt blower. The distributor implements independent blowing or a random blowing combination of the air flow paths on each floor to reach each floor. After being ventilated through the independent vents on each floor, it flows into the ventilation air duct assembly and returns to the cooling room. The space between the shelf 40 and the inner liner of the box 20 is sealed to prevent and control cold air from settling and affecting temperature fluctuations in the lower layer. On the display control panel, 2℃, 5℃, and 10℃ selection buttons (or low, medium, high) level selection are installed, and at the same time, storage type information is displayed to remind the user which item was placed in which zone. . When ventilation is required in the storage space 21 on the first floor (the storage space 21 on the uppermost side), the air comes out through the first blower, passes through the shelf 40, and reaches the bottle holder 31 and the first door body ( 30) is reached. Due to the installation of the first vent 81, the air is returned and ventilated through the first floor vent to complete one refrigeration cycle. When the temperature of the temperature sensor 51 corresponding to each floor storage space 21 reaches a predetermined temperature, the corresponding air outlet on the shunt blower is closed to stop blowing. The temperature between the shelf 40 and the bottle holder 31 is the same. The second floor storage space 21 (middle storage space 21) has the same air flow path circulation as the first floor storage space 21. Part of the air in the third floor storage space 21 (lowest storage space 21) passes through the shelf 40 and reaches the bottle holder 31 and the first door 30, and the remaining part reaches the drawer area. It transports cold air, and controls the cold energy rate of each floor through different sizes of vents to achieve a predetermined temperature balance. When the temperature sensor 51 detects that the temperature of the storage space 21 is high and requires blowing air, the distributor blows air to one floor. One independent air vent is installed in each storage space (21) and drawer space (22), and the size of each air vent goes through rigorous calculations and simulations, taking into account factors such as heat conduction and cooling capacity, and three first air vents from top to bottom. The area ratio of the four vents including the vent 81 and the second vent 82 is preferably 6:2.5:1.5:10.

The refrigerating and freezing device according to an embodiment of the present invention can implement temperature control for each multi-layer area of the refrigerating compartment. Each layer can realize three levels of temperature change. Users are free to select the temperature range according to their needs. The size ratio of the tuyeres is rigorously calculated to achieve temperature balance. The installation structure of the vent is an air flow path circulation method in which the vent, the shelf 40, and the bottle holder 31 are matched with each other to control temperature changes and humidity in the refrigerating and freezing device. Each display control panel is installed on the side wall of each storage space 21 for easy operation and may be located close to the first door 30. It is convenient for users to use because they can adjust it arbitrarily according to their habits. It can also reduce waste by guiding users to store food properly. You can extend the shelf life of foods that could not be stored in the refrigerator before by putting them in the refrigerator. Food can be stored in an optimal temperature and humidity environment, greatly improving preservation. Each floor zone is ventilated only when needed, saving energy by preventing food from getting too cold.
