Detailed ways

In order to solve at least one of the above technical problems, the present invention first provides a refrigeration and freezing device 1. Figure 1 is a schematic cross-sectional view of a refrigeration and freezing device 1 according to an embodiment of the present invention.

Referring to Figure 1, the refrigeration and freezing device 1 of the present invention includes a box 10. The box 10 defines a storage compartment 11 for storing items, a ripening compartment 12 for ripening items therein, and a cooling unit 10 for cooling. The refrigeration air duct 13 of the air flow is configured to selectively communicate with the storage compartment 11 and/or the ripening compartment 12 . That is to say, the refrigeration air duct 13 can be connected to the storage compartment 11 and the ripening compartment 12 at the same time, or it can be connected to one of the storage compartment 11 and the ripening compartment 12, or it can not be connected to the storage room. The chamber 11 communicates with any one of the aging chambers 12 .

In addition to the storage compartment 11 for general storage, the refrigeration and freezing device 1 of the present invention also has a ripening compartment 12. The user can directly place the items to be matured in the ripening compartment 12 for ripening, so that the user can Homemade cooked food. Furthermore, in the present invention, the ripening compartment 12 is configured such that the refrigeration air duct 13 is selectively connected to the storage compartment 11 and/or the ripening compartment 12, whereby the storage compartment 11 and the ripening compartment can be selectively supplied to the storage compartment 11 and the ripening compartment 12 at the same time. The cooling airflow is sent to the storage compartment 11 to lower the temperature of the storage compartment 11 and the ripening compartment 12 at the same time. The cooling airflow is only sent to the storage compartment 11 to lower the temperature of the storage compartment 11. The cooling airflow is only sent to the ripening compartment 12. To lower the temperature of the ripening compartment 12 or stop the cooling air flow into the storage compartment 11 and the ripening compartment 12, so as to use the refrigeration air duct 13 of the refrigeration and freezing device 1 to simultaneously cool the storage compartment 11 and the ripening compartment 12. Refrigeration, clever design, improves the utilization rate of cold air and reduces energy consumption.

At the same time, in order to continuously supply air to the surface of the object to be matured (especially meat food), the refrigeration and freezing device 1 of the present invention further includes an internal circulation fan 22, and the internal circulation fan 22 is configured to controllably promote ripening. The air flow in the chamber 12 circulates across the surface of the object to be matured. Each time the refrigeration air duct 13 stops delivering cooling air flow into the ripening compartment 12, the internal circulation fan 22 is turned on to drive the air flow in the ripening compartment 12 to circulate, that is, the internal circulation of the air flow in the ripening compartment 12 is realized. When the refrigeration air duct 13 delivers cooling airflow to the ripening chamber 12, the surface of the object to be matured already has a continuous air supply. Therefore, every time the refrigeration air duct 13 starts to deliver cooling airflow to the ripening chamber 12, Turn off the internal circulation fan 22 to avoid excessive surface wind speed in the maturation environment. The refrigeration and freezing device 1 of the present invention controls the start and stop state of the internal circulation fan 22 according to the temperature status/refrigeration conditions in the ripening compartment 12, thereby ensuring that the ripening compartment 12 always has a suitable ambient temperature and at the same time ensures ripening. The compartment 12 always has continuous air supply, thereby providing the best ripening environment for the products to be matured in real time, and improving the ripening effect of the products to be matured.

In some embodiments, as shown in Figure 1, the refrigeration air duct 13 of the refrigeration and freezing device 1 of the present invention is connected to the storage compartment 11 through the first air supply air duct 14, and is connected to the storage compartment 11 through the second air supply air duct 15. The 12 ripening rooms are connected. Moreover, the refrigeration and freezing device 1 also includes a refrigeration fan 21 to increase the cooling air flow in the refrigeration air duct 13 to be transported outward. The refrigeration fan 21 is configured to controllably introduce the cooling air flow in the refrigeration air duct 13 into the storage compartment 11 through the first air supply duct 14, and/or to control the cooling air flow in the refrigeration air duct 13 through the second air supply air duct. Road 15 introduces the ripening chamber 12. That is to say, when the refrigeration fan 21 is started, the cooling air flow in the refrigeration air duct 13 of the present invention can be selectively transported to the storage compartment 11 through the first air supply air duct 14 and all through the second air supply air duct. 15 is transported to the ripening room 12, and part of it is transported to the storage room 11 through the first air supply duct 14, while the other part is transported to the ripening room 12 through the second air supply duct 15, or the supply to the storage room is stopped at the same time. Chamber 11 and ripening chamber 12.

The refrigeration air duct 13 of the present invention communicates with the storage compartment 11 through the first air supply duct 14, and communicates with the ripening compartment 12 through the second air supply duct 15, and uses the refrigeration fan 21 to controlly disperse the refrigeration air. The cooling air flow in the duct 13 is introduced into the storage compartment 11 through the first air supply duct 14, and/or the cooling air flow in the refrigeration air duct 13 is introduced into the ripening compartment 12 through the second air supply duct 15, so that the storage The compartment 11 and the ripening compartment 12 share a refrigeration fan 21 and use two different air supply ducts to supply air, which ensures the accuracy of temperature control in the storage compartment 11 and the ripening compartment 12 and improves the temperature control. The utilization rate of the storage space of the refrigeration and freezing device 1 reduces production costs.

In some embodiments, as shown in FIG. 1 , the refrigeration and freezing device 1 of the present invention is provided with an evaporator 40 in the refrigeration air duct 13 . The evaporator 40 is used to exchange heat with the air flow to form a heat exchanger for the storage compartment 11 . and/or cooling air flow in the aging chamber 12. Specifically, the storage compartment 11 of the present invention is a refrigeration compartment, and the evaporator 40 is a refrigeration evaporator.

In some embodiments, the box 10 also defines an internal circulation air duct 16 that communicates with the maturation chamber 12 . As shown in Figure 1, the internal circulation air duct 16 is continuously distributed at the bottom and rear of the maturation chamber 12. The internal circulation fan 22 is provided in the internal circulation duct 16 and is located behind the ripening chamber 12 . Specifically, the internal circulation air duct 16 is embedded in the rear area of the refrigeration and freezing device 1, which does not occupy the ripening space and increases the effective working area in the ripening chamber 12. In addition, the present invention reduces the noise generated by the motor and the fan to a certain extent by arranging the internal circulation fan 22 in the encapsulated internal circulation duct 16. At the same time, it does not need to be installed inside the ripening chamber 12, and the appearance is beautiful and safe. High performance and improved user experience.

FIG. 2 is a schematic enlarged view of part A in FIG. 1 . Figure 3 is a schematic diagram of the air flow in which the refrigeration air duct 13 is simultaneously connected to the storage compartment 11 and the ripening compartment 12 according to an embodiment of the present invention. FIG. 4 is a schematic diagram of the air flow in which the refrigeration air duct 13 is only connected to the storage compartment 11 according to an embodiment of the present invention.

Figure 5 is a schematic diagram of the air flow in which the refrigeration air duct 13 is only connected to the ripening chamber 12 according to an embodiment of the present invention. Figure 6 is a schematic diagram of the air flow during internal circulation of the air flow in the ripening chamber 12 according to an embodiment of the present invention.

Referring to Figures 2 to 6, the maturation chamber 12 has a maturation air supply port 121 that allows external airflow to flow into it, an internal circulation return air port 122 that is connected to the internal circulation air duct 16, and an internal circulation air return port 122 that allows the internal airflow to escape back to the refrigeration air duct 13. Refrigeration return air outlet 123. In some embodiments, the ripening air supply port 121 is configured to selectively communicate with or disconnect from the second air supply duct 15 to control the conduction state between the refrigeration air duct 13 and the ripening chamber 12 .

Further, one end of the internal circulation air duct 16 is connected to the ripening chamber 12 through the internal circulation return air outlet 122, and the other end of the internal circulation air duct 16 is formed by converging with the air flow outlet of the second air supply air duct 15, and is connected with the ripening air supply outlet. 121 connected. The second damper 32 is provided, and the second damper 32 is configured to controllably open or close the air flow outlet of the second air supply duct 15, thereby controlling the communication state between the ripening chamber 12 and the refrigeration air duct 13. That is to say, the second air supply air duct 15 and the internal circulation air duct 16 share a ripening air outlet 121, which reduces the number of openings in the ripening chamber 12. On the one hand, it simplifies the structure of the refrigeration and freezing device 1 and reduces the cost. While reducing its cost, it also reduces the occupied area of the air duct structure, which is helpful for the design of the embedded air duct structure; on the other hand, it beautifies the appearance of the maturation chamber 12 and improves the user experience.

Specifically, when the second air door 32 is opened, that is, the air flow outlet of the second air supply duct 15 is opened, as shown in Figures 3 and 5, the second air supply duct 15 is connected to the ripening air outlet 121, so that the ripening room The chamber 12 can be connected to the refrigeration air duct 13 through the ripening air supply port 121 and the second air supply duct 15, so that driven by the refrigeration fan 21, the cooling air flow in the refrigeration air duct 13 can be smoothly sent from the refrigeration air supply port. After blowing over the surface of the objects to be matured, the ripening chamber 12 returns from the refrigeration return air outlet 123 to the refrigeration air duct 13, thereby reducing the ambient temperature in the ripening chamber 12 and ensuring the surface wind speed of the objects to be matured. When the second damper 32 is closed, that is, the air flow outlet of the second air supply duct 15 is closed, as shown in Figures 4 and 6, the cooling air flow in the refrigeration air duct 13 cannot enter the ripening chamber 12. At this time, the ripening The air supply port 121 is only connected to the internal circulation air duct 16. Under the impetus of the internal circulation fan 22, the air flow in the ripening chamber 12 circulates between the ripening chamber 125 and the internal circulation air duct 16, so that the ripening chamber 12 is not changed. While maintaining the internal ambient temperature, the surface wind speed of the items to be matured is ensured.

Further, the internal circulation air duct 16 includes an internal circulation return air duct 162 located between the internal circulation return air outlet 122 and the internal circulation fan 22, and an internal circulation air supply air located between the internal circulation fan 22 and the ripening air supply port 121. Road 161. The internal circulation return air duct 162 is semi-enclosed and distributed below and behind the ripening compartment 12 , and the internal circulation air supply duct 161 is located behind the ripening compartment 12 . That is to say, the entire internal circulation air duct 16 will not occupy the space of the ripening compartment 12, thereby increasing the effective working area in the ripening compartment 12 and improving the user experience.

In some specific embodiments, the ripening chamber 12 includes a shell 124 defining a ripening cavity 125 for containing items to be aged. As shown in Figures 1 and 2, the ripening air supply port 121 is opened on the rear top of the casing 124, and the ripening air outlet and refrigeration air return port 123 are opened on the front side of the casing 124, so as to facilitate the entry of the ripening cavity from the ripening air supply port 121. The airflow of 125 flows through the entire ripening chamber 125 as much as possible and then radiates out from the ripening air outlet or refrigeration return air outlet 123, extending the flow path of the airflow in the ripening chamber 125 as much as possible to ensure that all parts of the items to be matured can be obtained Blow dry. Preferably, the ventilation area of the ripening air outlet and the refrigeration return air outlet 123 is substantially the same as the ventilation area of the ripening air supply port 121, thereby achieving a more stable air flow in the ripening cavity 125. In addition, the height of the geometric center of the ripening air outlet and the refrigeration return air outlet 123 is lower than the height of the geometric center of the ripening air supply outlet 121 . In some specific embodiments, the uppermost sides of the ripening air outlet and the refrigeration return air outlet 123 are both lower than the uppermost side of the ripening air outlet, thereby achieving a more sufficient air circulation between the ripening space and the external space, further improving the ripening efficiency. The uniformity of air supply everywhere in the cavity 125 ensures that the products to be matured have a uniform ripening effect.

In some embodiments, the ripening cavity 125 is provided with a storage grid for placing items to be matured. The storage grid has a plurality of hollow meshes, and the storage grid is spaced apart from the bottom wall of the ripening cavity 125 to facilitate the simultaneous flow of air. The upper and lower surfaces of the items to be matured placed on the rack are blown, thereby ensuring that both the upper and lower surfaces of the items to be matured can achieve the air-drying effect as quickly as possible.

In some embodiments, a first damper 31 is provided at the airflow outlet of the first air supply duct 14, and the first damper 31 is configured to controllably open or close the airflow outlet of the first air supply duct 14, thereby controlling The communication state between the storage compartment 11 and the cooling air duct 13. Moreover, an air flow channel 126 is formed in the storage compartment 11 to allow the air flow in the storage compartment 11 to return to the refrigeration air duct 13 through the refrigeration return air duct 18 . In a specific embodiment, the ripening compartment 12 is disposed in the storage compartment 11 , and the ripening compartment 12 includes a shell 124 . The front plate and the bottom plate of the housing 124 are spaced apart from the door and the bottom wall of the storage compartment 11 respectively to form the above-mentioned airflow channel 126 . Specifically, the refrigeration return air outlet 123 of the ripening compartment 12 is provided on the front panel of the casing 124 , and the refrigeration return air outlet 123 is connected with the storage compartment 11 to allow the air flow in the ripening compartment 12 to enter from the refrigeration return air outlet 123 Storage compartment 11, and flows back to the refrigeration air duct 13 through the above-mentioned air flow channel 126 and the refrigeration return air duct 18.

Specifically, when the first air door 31 is opened, that is, the air flow outlet of the first air supply duct 14 is opened, as shown in Figures 3 and 4, the first air supply duct 14 is connected with the storage compartment 11, so that the storage compartment 11 is connected. The storage room 11 can be connected with the refrigeration air duct 13 through the first air supply duct 14. At this time, driven by the refrigeration fan 21, the cooling air flow in the refrigeration air duct 13 can be smoothly transported to the storage compartment 11. After flowing through the internal space of the storage compartment 11, it enters the refrigeration return air duct 18 from the above-mentioned airflow duct 126 and returns to the refrigeration air duct 13, thereby continuously reducing the ambient temperature in the storage compartment 11. When the first damper 31 is closed, that is, the air flow outlet of the first air supply duct 14 is closed, as shown in Figures 5 and 6, the cooling air flow in the cooling air duct 13 cannot be transported to the storage compartment 11, thus stopping the cooling. Cooling of storage room 11.

Referring to Figures 3 to 6 below, the refrigeration air duct 13 is connected to the storage compartment 11 and the ripening compartment 12 at the same time, is connected to one of the storage compartment 11 and the ripening compartment 12, and is not connected to the storage compartment. The air flow under four working conditions in which any one of the chamber 11 and the ripening chamber 12 is connected will be introduced.

When both the storage compartment 11 and the ripening compartment 12 need to be refrigerated, see FIG. 3 , the refrigeration fan 21 is turned on, the internal circulation fan 22 is turned off, and the first damper 31 and the second damper 32 are both opened. At this time, the refrigeration air duct 13 is connected to the storage compartment 11 through the first air supply duct 14. Driven by the refrigeration fan 21, the cooling air flow enters the storage compartment 11 from the first air supply duct 14. After passing through the internal space of the storage compartment 11, it enters the refrigeration return air duct 18 from the above-mentioned air flow channel 126 and returns to the refrigeration air duct 13, thereby realizing the refrigeration cycle of the storage compartment 11. At the same time, the refrigeration air duct 13 is connected to the maturation chamber 12 through the second air supply duct 15. Driven by the refrigeration fan 21, the cooling air flow in the refrigeration air duct 13 is sent from the refrigeration air supply port into the maturation chamber 12, and is blown After passing through the surface of the object to be matured, the self-refrigeration return air outlet 123 flows through the air flow channel 126 and the refrigeration return air duct 18 and returns to the refrigeration air duct 13, thereby realizing the refrigeration cycle of the ripening chamber 12.

When the storage compartment 11 needs to be refrigerated and the ripening compartment 12 does not need to be refrigerated, see Figure 4. The refrigeration fan 21 is turned on, the internal circulation fan 22 is turned on, the first damper 31 is opened, and the second damper 32 is closed. At this time, the cooling air duct 13 is only connected to the storage compartment 11 through the first air supply duct 14. Driven by the refrigeration fan 21, the cooling airflow enters the storage compartment 11 from the first air supply duct 14. After flowing through the internal space of the storage compartment 11, it enters the refrigeration return air duct 18 from the above-mentioned air flow channel 126 and returns to the refrigeration air duct 13, thereby realizing the refrigeration cycle of the storage compartment 11. At the same time, the refrigeration air supply port is only connected to the internal circulation air supply duct 161. Driven by the internal circulation fan 22, the air flow in the ripening chamber 125 enters the internal circulation return air duct 162 from the internal circulation return air port 122. The circulating air supply duct 161 then returns to the ripening chamber 125 from the ripening air supply port 121. That is to say, the air flow circulates in the ripening chamber 125, the internal circulation return air duct 162, the internal circulation fan 22, and the internal circulation air supply duct 161. The circulating flow between them realizes the internal circulation of the air flow in the ripening chamber 12.

When the storage compartment 11 does not need to be refrigerated and the ripening compartment 12 needs to be refrigerated, see Figure 5. The refrigeration fan 21 is turned on, the internal circulation fan 22 is turned off, the first damper 31 is closed, and the second damper 32 is opened. At this time, the refrigeration air duct 13 is only connected to the maturation chamber 12 through the second air supply duct 15. Driven by the refrigeration fan 21, the cooling air flow in the refrigeration air duct 13 is sent from the refrigeration air supply port into the maturation chamber 12, After blowing over the surface of the object to be matured, the self-refrigeration return air outlet 123 flows through the air flow channel 126 and the refrigeration return air duct 18 and returns to the refrigeration air duct 13, thereby realizing the refrigeration cycle of the ripening chamber 12.

When neither the storage compartment 11 nor the ripening compartment 12 needs to be refrigerated, see Figure 6, the refrigeration fan 21 is turned off, the internal circulation fan 22 is turned on, and the first damper 31 and the second damper 32 are both closed. At this time, the refrigeration air supply port is only connected to the internal circulation air supply duct 161. Driven by the internal circulation fan 22, the air flow in the ripening chamber 125 enters the internal circulation return air duct 162 from the internal circulation return air port 122. The internal circulation air supply duct 161 then returns to the ripening chamber 125 from the ripening air supply port 121. That is to say, the air flow flows through the ripening chamber 125, the internal circulation return air duct 162, the internal circulation fan 22, and the internal circulation air supply duct. The circulating flow between 161 realizes the internal circulation of the air flow in the ripening chamber 12.

The present invention also provides a control method for the refrigeration and freezing device 1 described in any of the above embodiments. Figure 7 is a schematic flow chart of a control method for the refrigeration and freezing device 1 according to one embodiment of the present invention. Refer to Figure 7 .

The material environment and the maturation environment of the material to be matured improve the user experience.

In some embodiments, the above step S704 may specifically include:

Compare the first ambient temperature with the first preset temperature threshold, and compare the second ambient temperature with the second preset temperature threshold.
