detailed description

The present invention firstly provides a refrigerating and freezing device, and FIG. 1 is a schematic structural diagram of a refrigerating and freezing device according to an embodiment of the present invention. The refrigerating and freezing device 1 of the present invention includes a box body 10 , and a refrigerating chamber 11 for storing items is defined in the box body 10 . Further, the box body 10 may also define a freezing room and/or a cooling room. The refrigerating compartment 11, the freezing compartment and the temperature-changing compartment are selectively opened or closed through doors pivotably arranged on the front side of the box body 10, respectively.

In particular, the refrigerating and freezing device 1 further includes a ripening device 20, which is arranged in the box body 10, and is used for ripening the food to be ripened therein. Thus, the low-temperature and high-humidity environment in the box body 10 can be effectively used to promote the ripening of the products to be ripened in the ripening device 20, and no special cooling device and humidifying device are required, which reduces the cost. The refrigerating and freezing device 1 integrated with the ripening device 20 not only has the traditional function of storing and keeping fresh in a low-temperature environment, but also has a ripening function, which enriches the functions of the refrigerating and freezing device 1 .

Fig. 2 and Fig. 3 are schematic cross-sectional views of the aging device according to one embodiment of the present invention, taken along vertical sectional planes in different orientations, and Fig. 4 is a schematic cross-sectional view of the maturing device according to one embodiment of the present invention, taken along the horizontal sectional plane . Further, the ripening device 20 is selectively communicated with the refrigerating chamber 11, that is to say, the maturing device 20 may communicate with the refrigerating chamber 11 under certain conditions, or may not communicate with the refrigerating chamber 11 under other conditions. The aging device 20 may include an internal circulation fan 25 and an external circulation fan 27 .

Figure 5 is a schematic diagram of the air flow path of the aging device when the internal circulation fan is independently activated according to an embodiment of the present invention, and Figure 6 is a schematic diagram of the air flow path of the aging device when the external circulation fan is independently activated according to an embodiment of the present invention. Referring to Fig. 5 and Fig. 6, the internal circulation fan 25 is used to promote the airflow in the ripening device 20 to circulate inside it, thus, the internal circulation fan 25 can be used to ensure the surface wind speed requirement of the ripened product. The external circulation fan 27 is used for controlling the airflow in the refrigerating chamber 11 to flow into the aging device 20 when the air humidity in the aging device 20 exceeds a preset maximum humidity threshold. Thus, when the humidity in the ripening device 20 is relatively high (for example, the product to be ripened has just been put in), the airflow with a relatively low humidity in the refrigerating chamber 11 can be introduced into the ripening device 20 by using the external circulation fan 27, so as to properly reduce the humidity. The humidity in the ripening device 20 avoids spoilage of the ripened product.

Specifically, the refrigerating room 11 has a storage environment for refrigerating and keeping fresh, and the temperature therein is approximately between 0°C and 8° C., and the humidity in the refrigerating room 11 is usually higher than that of the indoor environment, which is more suitable for keeping food fresh. The ripening device 20 is usually closed. When the food is just put into the ripening device 20 in the early stage of ripening, the food itself has a large water content and a lot of volatile water, which leads to excessive humidity inside the ripening device 20, which may exceed the temperature of the food to be ripened. The highest humidity threshold (eg 90%) required for aging, thus causing food spoilage. At this time, the humidity in the refrigerator compartment 11 is relatively low, and the humidity in the refrigerator compartment 11 can be reduced by introducing the airflow in the refrigerator compartment 11 into the ripening device 20 , which does not require a special dehumidification device and simplifies the structure of the ripening device 20 .

It can be seen that after the application integrates the aging device 20 on the refrigeration and freezing device 1, the original storage environment in the refrigeration and freezing device 1 is fully utilized to realize the aging environment with suitable temperature and humidity in the aging device 20. The design idea is novel and the structure is ingenious , and greatly reduce the cost.

In some embodiments, the ripening device 20 is arranged in the refrigerator compartment 11, and includes an external air inlet 211 for the airflow in the refrigerator compartment 11 to flow into it and an external air outlet for the airflow inside the ripening device 20 to flow out. 212. The external air inlet 211 communicates with the air inlet of the external circulation fan 27 , and the external air inlet 211 and/or the external air outlet 212 are selectively opened or closed by dampers. That is to say, after the aging device 20 is installed in the refrigerator compartment 11, it is only necessary to open an external air inlet 211 on the aging device 20, and the air in the refrigerator compartment 11 can be made under the action of the external circulation fan 27 without setting up an additional air duct. The air flow directly enters the aging device 20 through the external air inlet 211, which simplifies the structure. Moreover, the opening and closing of the external air inlet 211 and the external air outlet 212 are adjustable and controllable through the damper, avoiding the problem that the external air inlet 211 and the external air outlet 212 are always open, which may easily lead to the problem of mutual odors between the interior of the aging device 20 and the interior of the refrigerator compartment 11 , it can also form a relatively closed environment in the ripening device 20, which is beneficial to the ripening of the products to be ripened.

Specifically, the external air inlet 211 communicates with the airflow inlet of the external circulation fan 27 and the refrigerator compartment 11 . In one embodiment, the external air outlet 212 can communicate with the inside of the aging device 20 and the cold storage room 11 , so that the air flow from the aging device 20 can return to the cold storage room 11 . At this time, there is no need to set up an air duct, and the external circulation fan 27 drives the airflow to circulate between the interior of the aging device 20 and the refrigerating room 11. Humidity regulation is faster. In another embodiment, the external air outlet 212 can also communicate with the inside of the maturing device 20 and other compartments in the box 10, such as an evaporator chamber for accommodating an evaporator, so that the air flow out of the maturing device 20 flow to the evaporator chamber. At this time, the external circulation fan 27 can drive the airflow to circulate between the interior of the ripening device 20, the refrigerating chamber 11 and the evaporator chamber, and the humidity of the airflow in the evaporator chamber is lower than that in the refrigerating chamber 11. Quickly adjust the humidity in the aging device 20.

In some embodiments, the ripening device 20 further includes an outer casing 21 and an inner casing 22 disposed inside the outer casing 21 , and an air supply channel 24 is defined between the outer casing 21 and the inner casing 22 . The inside of the inner casing 22 is defined with a maturation chamber 23 for accommodating the food to be matured. The maturation chamber 23 communicates with the airflow inlet of the inner circulation fan 25 through the inner air return port 224 provided on the inner casing 22, and through the interior The internal air outlet 222 on the housing 22 communicates with the air passage 24 . The internal circulation fan 25 is used to drive the airflow inside the outer casing 21 to circulate between the air supply channel 24 and the aging chamber 23 . The air outlet of the external circulation fan 27 communicates with the air supply channel 24 to drive the air flow in the refrigerator compartment 11 to flow to the aging chamber 23 through the external air inlet 211, the air supply channel 24 and the internal air supply opening 222, and to make the air in the aging room 23 The air flows to the outside of the aging device 20 through the external air outlet 212 .

That is to say, the ripening device 20 adopts an inner and outer two-layer shell structure, the inner shell 22 forms a ripening chamber 23 , and the inner shell 22 and the outer shell 21 form an air supply channel 24 . No matter the airflow driven by the internal circulation fan 25 or the external circulation fan 27 is sent to the aging chamber 23 through the air supply channel 24, and the two share the air supply channel 24, which not only simplifies the structure, but also facilitates the passage of the air supply channel 24. The design of the extended path transports the air flow therein to the aging chamber 23 relatively uniformly, so as to improve the aging effect of the products to be aged.

In some embodiments, the lateral sides of the inner casing 22 are spaced apart from the lateral sides of the outer casing 21 to form two air supply channels 24 . Two air supply passages 24 extend along the longitudinal direction (ie perpendicular to the transverse direction) of the inner housing 22 and the outer housing 21 , and the air supply passages 24 are located laterally outside the inner housing 22 and laterally inside the outer housing 21 . That is to say, the lateral side plate 221 on one side of the inner housing 22 is spaced from the lateral side wall on this side of the outer housing 21, thereby forming one of the air supply passages 24; the other side of the inner housing 22 The lateral side plate 221 on one side is spaced apart from the lateral side wall of the housing 21 on this side, thereby forming another air supply channel 24 .

Further, the internal air outlets 222 are defined on the two lateral side panels 221 of the inner casing 22 . That is to say, each lateral side plate 221 is provided with an internal air outlet 222 . Thus, the airflow in the two air supply channels 24 can be allowed to be sent to the aging chamber 23 through the internal air supply openings 222 on the two lateral side plates 221 respectively. When the internal circulation fan 25 is activated, the internal air flows into the aging chamber 23 from the two lateral sides of the aging chamber 23 at the same time, which improves the uniformity of the air supply in the lateral direction of the aging chamber 23, thereby improving the aging effect of the products to be matured . When the external circulation fan 27 is activated, the airflow in the refrigerating chamber 11 flows into the aging chamber 23 from the two lateral sides of the aging chamber 23 at the same time, which improves the uniformity of the air supply in the lateral direction of the aging chamber 23, thereby quickly and evenly The humidity in the ripening chamber 23 is adjusted accurately.

In some embodiments, there are multiple air supply ports 222, and the number and/or size of the multiple air supply ports 222 are set to make the air flow sent to all parts of the aging chamber 23 uniform, which further improves the aging effect of the products to be matured. .

Specifically, each lateral side plate 221 of the inner casing 22 has multiple air outlets 222 . The arrangement of the air outlets 222 on the two lateral side plates 221 can be arranged symmetrically.

Further, the size of each air supply port 222 is the same, and the arrangement density of the plurality of air supply ports 222 on each lateral side plate 221 in the height direction of the inner casing 22 is uniform. The air outlets 222 on the two lateral side plates 221 are arranged at the same density in the height direction of the inner casing 22 . Thus, the uniformity of the air supply in the height direction of the aging chamber 23 can be improved, which not only ensures that the upper surface and the lower surface of the object to be matured have a uniform air blowing effect; but also makes the aging chamber 23 in the height direction. Humidity regulation in each area is relatively uniform.

Specifically, multiple air supply ports 222 on the same lateral side plate 221 may be arranged in multiple rows and multiple columns, and the hole spacing between any two adjacent air supply ports 222 in the height direction is the same.

The applicant realizes that by using an internal circulation fan 25 or an external circulation fan 27 to drive the airflow in the two air supply passages 24 to flow to the aging chamber 23, the internal circulation fan 25 and the external circulation fan 27 must be located at the ends of the two air supply passages 24. upstream. Therefore, in the flow direction of the airflow in the air supply channel 24 (ie, the longitudinal direction of the inner housing 22), the flow velocity of the airflow gradually decreases. For this reason, when the size of each air supply port 222 is the same, the arrangement density of the plurality of air supply ports 222 on each lateral side plate 221 in the direction of air flow in the air supply channel 24 increases stepwise or gradually. .

Thus, the defect that the airflow velocity in the airflow channel 24 decreases gradually in the direction of the airflow flow can be compensated for by increasing the arrangement density of the airflow ports 222, thereby improving the uniformity of the airflow in the longitudinal direction of the aging chamber 23, and not only It is ensured that each region of the surface of the object to be matured in the longitudinal direction has a uniform airflow blowing effect, and the humidity adjustment of each region of the aging chamber 23 in the longitudinal direction is relatively uniform.

Specifically, in one embodiment, the arrangement density of the plurality of air supply openings 222 on the lateral side plate 221 in the flow direction of the airflow in the air supply channel 24 increases step by step. That is to say, the transverse side plate 221 can be divided into several sections in the longitudinal direction, and the distribution density of the air supply ports 222 in each section is the same in the airflow direction, and the several sections arranged in sequence along the airflow direction The arrangement density of the air outlets 222 in each section increases gradually. Specifically, multiple air supply ports 222 on the same lateral side plate 221 can be arranged in multiple rows and multiple columns, and the hole spacing between any two adjacent air supply ports 222 in the direction of air flow in the same section is the same. same. The hole spacing between two adjacent air supply ports 222 in the longitudinal direction of the inner housing of several sections arranged in sequence along the air flow direction increases gradually.

In another embodiment, the arrangement density of the plurality of air supply openings 222 on the lateral side plate 221 gradually increases along the flow direction of the airflow in the air supply channel 24 . That is to say, the density increase of the air outlets 222 is uniform in the air flow direction. Specifically, multiple air supply ports 222 on the same lateral side plate 221 can be arranged in multiple rows and multiple columns, and the hole spacing between two adjacent air supply ports 222 in the direction of airflow flow increases equidistantly.

It can be seen that, through the special design of the air supply channel 24 and the air supply port 222 in this application, uniform air blowing effect and relatively uniform humidity can be obtained for the food to be matured in the horizontal direction, height direction and vertical direction, and the food to be matured The ripening effect is better.

In some embodiments, the inner housing 22 further includes an end plate 223 connected between the two lateral side plates 221 , and the internal air return port 224 is opened on the end plate 223 . The external air inlet 211 is opened on the shell wall of the outer shell 21 opposite to the end plate 223 . The external air outlet 212 is located on the other side of the aging device 20 opposite to the side where the end plate 223 is located, and communicates with the refrigerator compartment 11 . Both the inner circulation fan 25 and the outer circulation fan 27 are arranged between the outer casing 21 and the inner casing 22 .

Thus, both the internal airflow flowing into the aging chamber 23 and the external airflow from the refrigerating chamber 11 can flow out from the internal air return port 224 and the external air outlet 212 after passing through a relatively long path in the aging chamber 23 . The blowing time of the internal airflow on the surface of the mature object is longer, which fully exerts the air-drying effect of the airflow on the surface of the mature object. The path of the external airflow flowing through the maturation chamber 23 is relatively long, which can fully cover each area in the maturation chamber 23, and the humidity regulation effect is better.

In some embodiments, the outer circulation fan 27 is located on the outer side of the inner circulation fan 25 away from the inner casing 22 . The outer circulation fan 27 and the inner circulation fan 25 can be separated by a partition plate 28 to avoid the influence of the air supply air path of the two fans. Both the external circulation fan 27 and the internal circulation fan 25 are located at the rear side of the aging device 20, that is, the end plate 223 is the rear end plate. On the rear side of the box body 10, the user is not easy to feel the noise generated when the fan is running.

Further, both the inner circulation fan 25 and the outer circulation fan 27 are centrifugal fans with one-way air inlet and two-way air outlet. Therefore, not only can the air flow be blown to the two air supply channels 24 in two opposite directions at the same time, but also reduce the space occupied by the inner circulation fan 25 and the outer circulation fan 27, making the structure of the aging device 20 more compact , The volume is smaller, so as to avoid occupying too much space in the box body 10 .

In some embodiments, the outer casing 21 is a cylinder with a front opening. The inner casing 22 is a drawer with an open top, and the inner casing 22 is arranged in the outer casing 21 in a push-pull manner.

That is to say, the outer casing 21 of the ripening device 20 is in the form of a cylinder, and the inner casing 22 is in the form of a drawer. Putting in the food to be ripened or taking out the food to be ripened from the ripening chamber 23 improves the convenience of the user's operation.

In some embodiments, the inner casing 22 is provided with a storage grid 26 for shelving objects to be ripened. The storage grid 26 has a plurality of hollow mesh holes, and the storage grid 26 is spaced apart from the bottom plate of the inner casing 22. .

That is to say, there is a certain space above and below the rack 26, and the rack 26 is hollowed out to facilitate the airflow to blow the upper and lower surfaces of the objects to be matured on the rack 26, thereby ensuring Both the upper surface and the lower surface of the object to be matured can reach the air-drying effect as soon as possible.

Moreover, the hollowed-out rack 26 also reduces the contact area between the object to be ripened and the grid rack 26, which prevents parts of the surface of the object to be ripened from being spoiled due to lack of airflow.

The present invention also provides a control method for the refrigerating and freezing device 1 described in any one of the above embodiments, the control method comprising:

Obtain the air humidity in the aging device 20;

When the air humidity in the ripening device 20 exceeds the preset maximum humidity threshold, start the external circulation fan 27 to blow the airflow in the refrigerator compartment 11 into the ripening device 20; when the air humidity in the ripening device 20 is less than or equal to the preset maximum humidity Independently start the internal circulation fan 25 to promote the airflow in the aging device 20 to circulate inside it.

As a result, the original storage environment in the refrigerating and freezing device 1 is fully utilized to realize a ripening environment with suitable temperature and humidity in the aging device 20, the design idea is novel, the structure is ingenious, and the cost is greatly reduced.

Specifically, the above-mentioned preset maximum humidity threshold may be the highest humidity that can ensure that the ripened product achieves a ripening effect. For different types of products to be ripened, the value of the preset maximum humidity threshold may be different. For example, for the aging of meat, the preset maximum humidity threshold may be any humidity value between 85% and 95%.

Fig. 7 is a schematic flowchart of a control method of a refrigerating and freezing device according to an embodiment of the present invention. In a specific embodiment, the control method of the present invention may specifically include:

Step S101, obtaining the air humidity in the aging device 20;

Step S102, judging whether the air humidity in the aging device 20 exceeds the preset maximum humidity threshold; if so, go to step S103, if it is enough, go to step S104;

Step S103, start the external circulation fan 27 to blow the airflow in the refrigerating chamber 11 into the aging device 20;

Step S104, independently start the internal circulation fan 25, so as to promote the airflow in the aging device 20 to circulate inside it.

It can be understood that when the external circulation fan 27 is activated, the internal circulation fan 25 may not be activated to avoid air flow disturbance.

In some embodiments, the external air inlet 211 and the external air outlet 212 are respectively provided with a first damper 213 and a second damper 214 . In these embodiments, the control method of the present invention also includes:

When the air humidity in the aging device 20 exceeds the preset maximum humidity threshold, the first damper 213 and the second damper 214 are controlled to open the external air inlet 211 and the external air outlet 212 respectively; the air humidity in the aging device 20 is less than or equal to the preset When the humidity is the highest, the first damper 213 and the second damper 214 are controlled to close the external air inlet 211 and the external air outlet 212 respectively.

That is to say, in some other embodiments, the above step S103 may further include: controlling the first damper 213 and the second damper 214 to respectively open the external air inlet 211 and the external air outlet 212 . The above step S104 may further include: controlling the first damper 213 and the second damper 214 to close the external air inlet 211 and the external air outlet 212 respectively. Thereby, it is possible to avoid the generation of cross-smell or unnecessary air flow between the ripening device 20 and the refrigerating chamber 11 when the external circulation fan 27 does not need to be activated.

Those skilled in the art should understand that the refrigerating and freezing device 1 of the present invention can be a cross-by-side refrigerator, and the aging device 20 communicates with one of the refrigerating chambers 11 at the upper part.

In some other embodiments, the refrigerating and freezing device 1 may not be limited to the refrigerator structure shown in FIG. 1 , but may also be a double-door refrigerator, and the ripening device 20 communicates with the upper refrigerating chamber.

In some other embodiments, the refrigerating and freezing device 1 may not be limited to the refrigerator structure shown in FIG. 1 , but may also be a three-door refrigerator, and the ripening device 20 communicates with the upper refrigerating chamber.
