Detailed Description
The present invention first provides a refrigerating and freezing apparatus, and fig. 1 is a schematic structural view of a refrigerating and freezing apparatus according to an embodiment of the present invention. The refrigerating and freezing apparatus 1 of the present invention includes a cabinet 10, and a refrigerating chamber 11 for storing articles is defined in the cabinet 10. Further, the housing 10 may also define a freezer compartment and/or a temperature change compartment. The refrigerating chamber 11, the freezing chamber and the temperature varying chamber are selectively opened or closed by a door body pivotably provided at the front side of the cabinet 10, respectively.
In particular, the refrigerating and freezing apparatus 1 further includes a ripening device 20, and the ripening device 20 is provided in the case 10 for ripening the to-be-ripened substance therein. Therefore, the low-temperature and high-humidity environment in the box body 10 can be effectively utilized to promote the ripening of the to-be-ripened matters in the ripening device 20, a special cooling device and a special humidifying device are not required, and the cost is reduced. The refrigerating and freezing device 1 integrated with the ripening device 20 not only has the function of preserving the stored articles in the traditional low-temperature environment, but also has the ripening function, thereby enriching the functions of the refrigerating and freezing device 1.
Fig. 2 and 3 are schematic cross-sectional views of the ripening apparatus according to one embodiment of the present invention taken along vertical cross-sections of different orientations, and fig. 4 is a schematic cross-sectional view of the ripening apparatus according to one embodiment of the present invention taken along horizontal cross-sections. Further, the ripening device 20 is selectively communicated with the refrigerating chamber 11, that is, the ripening device 20 may be communicated with the refrigerating chamber 11 under certain conditions or may not be communicated with the refrigerating chamber 11 under other conditions. The curing apparatus 20 may include an inner circulation fan 25 and an outer circulation fan 27.
Fig. 5 is a schematic view of an airflow path of the ripening apparatus according to an embodiment of the present invention when the inner circulation blower is started alone, and fig. 6 is a schematic view of an airflow path of the ripening apparatus according to an embodiment of the present invention when the outer circulation blower is started alone. Referring to fig. 5 and 6, the internal circulation fan 25 is used to promote the air flow in the ripening device 20 to circulate inside, thereby ensuring the surface wind speed of the to-be-ripened objects by using the internal circulation fan 25. The external circulation fan 27 is used to controllably induce the air flow in the refrigerator compartment 11 into the interior of the ripening device 20 when the humidity of the air in the ripening device 20 exceeds a preset maximum humidity threshold. Thus, when the humidity in the ripening device 20 is high (for example, the to-be-ripened object is just put in), the air flow with relatively low humidity in the refrigerating chamber 11 can be introduced into the ripening device 20 by using the external circulation fan 27 to properly reduce the humidity in the ripening device 20 and avoid the to-be-ripened object from spoiling.
Specifically, the refrigerating chamber 11 has a refrigerated and fresh-keeping storage environment, the temperature in the storage environment is approximately between 0 ℃ and 8 ℃, and the humidity in the refrigerating chamber 11 is generally higher than the humidity in the indoor environment, so that the storage environment is more suitable for the fresh-keeping of food materials. The ripening apparatus 20 is typically closed, and the food itself contains a relatively high moisture content and a relatively high volatile moisture content during the early ripening stage of the food just placed in the ripening apparatus 20, which results in excessive humidity inside the ripening apparatus 20 and may exceed the maximum humidity threshold (e.g., 90%) required for ripening of the food to be ripened, thereby causing spoilage of the food. At this time, the humidity in the refrigerating chamber 11 is relatively small, and the humidity in the refrigerating chamber 11 can be reduced by introducing the air flow into the ripening device 20, without a special dehumidifying device, simplifying the structure of the ripening device 20.
Therefore, after the ripening device 20 is integrated on the refrigerating and freezing device 1, the original storage environment in the refrigerating and freezing device 1 is fully utilized to realize the ripening environment with proper temperature and humidity in the ripening device 20, so that the design thought is novel, the structure is ingenious, and the cost is reduced to a great extent.
In some embodiments, the ripening device 20 is disposed inside the refrigerating chamber 11 and includes an external air inlet 211 for the air flow inside the refrigerating chamber 11 to flow into the inside thereof and an external air outlet 212 for the air flow inside the ripening device 20 to flow out. The external air inlet 211 communicates with an 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 a damper. That is, after the ripening device 20 is disposed in the refrigerating chamber 11, only the external air inlet 211 is required to be formed in the ripening device 20, and the air flow in the refrigerating chamber 11 can directly enter the ripening device 20 through the external air inlet 211 under the action of the external circulating fan 27 without providing an additional air channel, so that the structure is simplified. In addition, the opening and closing of the external air inlet 211 and the external air outlet 212 are adjustable and controllable through the air door, so that the problem that the interior of the ripening device 20 and the interior of the refrigerating chamber 11 are mutually and mutually connected with each other easily due to the fact that the external air inlet 211 and the external air outlet 212 are always opened is avoided, a relatively closed environment can be formed in the ripening device 20, and the ripening of the to-be-ripened objects is facilitated.
Specifically, the external air intake 211 communicates the air flow inlet of the external circulation fan 27 with the refrigerating compartment 11. In one embodiment, the external air outlet 212 may communicate the interior of the ripening device 20 with the refrigerating compartment 11 so that the air flow from the ripening device 20 returns to the refrigerating compartment 11. At this time, it is not necessary to provide an air duct, and the external circulation fan 27 drives the air flow to circulate between the inside of the ripening device 20 and the refrigerating chamber 11, and the flow path is short, the driving force is strong, and the flow rate of the air flow is fast, so that the humidity adjusting speed in the ripening device 20 is fast. In another embodiment, the external air outlet 212 may also communicate the interior of the curing device 20 with other compartments within the housing 10, such as an evaporator compartment for housing an evaporator, so that air flow from the curing device 20 flows to the evaporator compartment. At this time, the external circulation fan 27 can drive the air flow to circulate between the refrigerator compartment 11 and the evaporator compartment inside the ripening device 20, and the humidity of the air flow in the evaporator compartment is lower than the humidity of the air flow in the refrigerator compartment 11, so that the humidity in the ripening device 20 can be adjusted relatively quickly.
In some embodiments, the curing apparatus 20 further includes an outer housing 21 and an inner housing 22 disposed within the outer housing 21, with an air supply passage 24 defined between the outer housing 21 and the inner housing 22. The inside of the inner casing 22 defines a ripening chamber 23 for containing a ripening substance, and the ripening chamber 23 communicates with an air flow inlet of an inner circulation fan 25 through an inner return air inlet 224 formed in the inner casing 22 and communicates with an air supply passage 24 through an inner air supply outlet 222 formed in the inner casing 22. The internal circulation fan 25 is used for driving the air flow in the outer casing 21 to circulate between the air supply passage 24 and the curing chamber 23. The air flow outlet of the external circulation fan 27 is communicated with the air supply channel 24 to drive the air flow in the refrigerating chamber 11 to flow to the ripening chamber 23 through the external air inlet 211, the air supply channel 24 and the internal air supply 222 in sequence, and to flow the air flow in the ripening chamber 23 to the outside of the ripening device 20 through the external air outlet 212.
That is, the curing device 20 has a two-layered structure of an inner and an outer casing, a curing chamber 23 is formed in the inner casing 22, and an air supply passage 24 is formed in the outer casing 21 and the outer casing 22. The air flow driven by the inner circulation fan 25 and the outer circulation fan 27 is sent to the ripening chamber 23 through the air supply channel 24, and the two air supply channels 24 are shared, so that the structure is simplified, and the air flow in the air supply channel 24 is conveniently and relatively uniformly conveyed to the ripening chamber 23 through the design of the extending path of the air supply channel 24, so that the ripening effect of the to-be-ripened matters is improved.
In some embodiments, the lateral sides of the inner housing 22 are spaced apart from the lateral sides of the outer housing 21, respectively, to form two air supply channels 24. Both of the air supply passages 24 extend in the longitudinal direction (i.e., a direction perpendicular to the lateral direction) of the inner case 22 and the outer case 21, and the air supply passages 24 are located laterally outside the inner case 22 and laterally inside the outer case 21. That is, the lateral side plate 221 of one side of the inner case 22 is spaced apart from the lateral side wall of the outer case 21 at the side, thereby forming one of the air supply passages 24; the other lateral side plate 221 of the inner casing 22 is spaced apart from the lateral side wall of the outer casing 21 on the side, thereby forming another air supply passage 24.
Further, the inner air supply opening 222 is opened at both lateral side plates 221 of the inner casing 22. That is, each lateral side plate 221 is provided with an internal air supply port 222. This allows the air flows in the two air supply passages 24 to be sent to the curing chamber 23 through the inner air supply openings 222 in the two lateral side plates 221, respectively. When the internal circulation fans 25 are started, the internal air flows from both lateral sides of the ripening chamber 23 into the ripening chamber 23 at the same time, improving the uniformity of the air flow in the lateral direction of the ripening chamber 23, thereby improving the ripening effect of the to-be-ripened matters. When the external circulation fan 27 is started, the air flow in the refrigerating compartment 11 simultaneously flows into the ripening compartment 23 from both lateral sides of the ripening compartment 23, improving the uniformity of the air flow in the lateral direction of the ripening compartment 23, thereby rapidly and uniformly adjusting the humidity in the ripening compartment 23.
In some embodiments, the number of the air outlets 222 is plural, and the number and/or the size of the plurality of air outlets 222 are set so that the air flow to the ripening chamber 23 is uniform, thereby further improving the ripening effect of the to-be-ripened objects.
Specifically, the number of the air outlets 222 on each lateral side plate 221 of the inner casing 22 is plural. The arrangement of the plurality of air outlets 222 on the two lateral side plates 221 may be symmetrically arranged.
Further, the size of each air outlet 222 is uniform, and the distribution density of the plurality of air outlets 222 on each lateral side plate 221 in the height direction of the inner casing 22 is uniform. The plurality of 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. Thereby, the uniformity of the air supply in the height direction of the ripening chamber 23 can be improved, and not only the uniform air flow blowing effect of the upper surface and the lower surface of the to-be-ripened object is ensured; but also the humidity adjustment of each area of the ripening chamber 23 in the height direction can be made relatively uniform.
Specifically, the plurality of air outlets 222 on the same lateral side plate 221 may be arranged in a plurality of rows and columns, and the hole spacing between any two adjacent air outlets 222 in the height direction may be the same.
The applicant has appreciated that the air flow in the two air supply channels 24 is driven to the ripening chamber 23 by means of one inner circulation fan 25 or one outer circulation fan 27, the inner circulation fan 25 and the outer circulation fan 27 necessarily being upstream of the two air supply channels 24. Accordingly, the flow velocity of the air flow gradually decreases in the air flow direction in the air supply passage 24 (i.e., the longitudinal direction of the inner housing 22). For this reason, when the sizes of the air outlets 222 are the same, the arrangement density of the plurality of air outlets 222 on each lateral side plate 221 in the air flow direction in the air flow passage 24 is stepwise increased or gradually increased.
Therefore, the defect that the airflow velocity in the air supply channel 24 decreases in the airflow flowing direction can be overcome by increasing the arrangement density of the air supply openings 222, so that the air supply uniformity of the ripening chamber 23 in the longitudinal direction is improved, the uniform air supply blowing effect of the surface of the to-be-ripened matters in the longitudinal direction is ensured, and the humidity adjustment of the ripening chamber 23 in the longitudinal direction is uniform.
Specifically, in one embodiment, the arrangement density of the plurality of air outlets 222 on the lateral side plate 221 in the air flow direction in the air flow passage 24 is stepwise increased. That is, the lateral side plate 221 may be divided into a plurality of sections in the longitudinal direction, and the distribution density of the air outlets 222 in each section in the airflow direction is the same, and the distribution density of the air outlets 222 in the plurality of sections sequentially arranged along the airflow direction gradually increases. Specifically, the plurality of air outlets 222 on the same lateral side plate 221 may be arranged in a plurality of rows and columns, and the hole spacing between any two adjacent air outlets 222 in the airflow direction in the same section is the same. The hole pitch between two air inlets 222 adjacent in the inner casing longitudinal direction of the sections arranged in order along the air flow direction gradually increases.
In another embodiment, the arrangement density of the plurality of air outlets 222 on the lateral side plate 221 in the air flow direction in the air flow channel 24 is gradually increased. That is, the degree of increase in the arrangement density of the air supply ports 222 in the air flow direction is uniform. Specifically, the plurality of air outlets 222 on the same lateral side plate 221 may be arranged in a plurality of rows and columns, and the hole spacing between two adjacent air outlets 222 in the air flow direction may be increased equidistantly.
Therefore, the air supply channel 24 and the air supply opening 222 are specially designed, so that the to-be-cooked object can obtain uniform air flow blowing effect and uniform humidity in the transverse direction, the height direction and the longitudinal direction, and the to-be-cooked object has good ripening effect.
In some embodiments, the inner housing 22 further includes an end plate 223 connected between its two lateral side plates 221, with an internal return air port 224 opening onto the end plate 223. The external air inlet 211 is formed in a housing wall of the outer housing 21, which is disposed opposite to the end plate 223. The external air outlet 212 is located at the other side of the ripening device 20 opposite to the side where the end plate 223 is located, and communicates with the refrigerating chamber 11. The inner circulation fan 25 and the outer circulation fan 27 are each disposed between the outer case 21 and the inner case 22.
Thus, both the internal air flow flowing into the ripening chamber 23 and the external air flow from the refrigerating chamber 11 can flow through a long path in the ripening chamber 23 and then flow out from the internal return air port 224 and the external air outlet port 212, respectively. The internal air flow blows for a longer time on the surface of the to-be-cooked object, and fully plays the air drying role of the air flow to-be-cooked object. The external air flow has a longer path through the ripening chamber 23, and can cover all areas in the ripening chamber 23, so that the humidity adjusting effect is better.
In some embodiments, the outer circulation fan 27 is located outside of the inner circulation fan 25 away from the inner housing 22. The outer circulation fan 27 and the inner circulation fan 25 can be separated by a separation plate 28, so as to avoid the influence of the supply air paths of the two fans. The outer circulation fan 27 and the inner circulation fan 25 are both positioned at the rear side of the ripening device 20, that is, the end plate 223 is a rear end plate, and when the ripening device 20 is placed in the box 10, the inner circulation fan 25 and the outer circulation fan 27 are both positioned at the rear side of the box 10, so that a user does not easily feel noise generated when the fans are operated.
Further, the inner circulation fan 25 and the outer circulation fan 27 are centrifugal fans with unidirectional air inlet and bidirectional air outlet. Therefore, not only the air flows can be blown to the two air supply channels 24 respectively in the two opposite directions at the same time, but also the space occupied by the inner circulation fan 25 and the outer circulation fan 27 is reduced, so that the structure of the curing device 20 is more compact and the volume is smaller, thereby avoiding occupying too much space in the case 10.
In some embodiments, the outer housing 21 is a cylinder with a front side opening. The inner housing 22 is a drawer with an open top, and the inner housing 22 is slidably disposed in the outer housing 21.
That is, the outer casing 21 of the ripening device 20 is in a cylindrical form, the inner casing 22 is in a drawer form, and the inner casing 22 is slidably disposed in the outer casing 21, so that the to-be-ripened object is conveniently put into the ripening chamber 23 in the inner casing 22 or taken out from the ripening chamber 23, thereby improving the convenience of the user's operation.
In some embodiments, the inner housing 22 is provided with a rack 26 for placing the to-be-cooked objects, the rack 26 has a plurality of hollow meshes, and the rack 26 is spaced from the bottom plate of the inner housing 22.
That is, the upper and lower parts of the rack 26 have a certain space, and the rack 26 is hollowed out, so that the airflow can blow the upper and lower surfaces of the to-be-cooked objects placed on the rack 26 at the same time, thereby ensuring that the upper and lower surfaces of the to-be-cooked objects can reach the air drying effect as soon as possible.
In addition, the hollow-out storage net frame 26 also reduces the contact area between the to-be-cooked object and the storage net frame 26, and avoids the putrefaction and deterioration of part of the surface of the to-be-cooked object caused by the fact that the to-be-cooked object cannot be contacted with air flow.
The present invention also provides a control method of the refrigerating and freezing apparatus 1 described in any of the above embodiments, the control method comprising:
acquiring the air humidity in the ripening device 20;
starting the external circulation fan 27 to blow the air flow in the refrigerating compartment 11 into the ripening device 20 when the air humidity in the ripening device 20 exceeds a preset maximum humidity threshold; the internal circulation fans 25 are individually activated when the air humidity in the ripening device 20 is equal to or less than a preset maximum humidity to promote the circulation of the air flow in the ripening device 20.
Therefore, the original storage environment in the refrigerating and freezing device 1 is fully utilized to realize the ripening environment with proper temperature and humidity in the ripening device 20, the design thought is novel, the structure is ingenious, and the cost is reduced to a great extent.
Specifically, the preset maximum humidity threshold may be the maximum humidity that can ensure that the to-be-cooked object achieves the ripening effect. The preset maximum humidity threshold may be different for different types of to-be-cooked products. For example, for meat ripening, the preset maximum humidity threshold may be any humidity value between 85% and 95%.

It will be appreciated that when the outer circulation fan 27 is activated, the inner circulation fan 25 may not be activated to avoid turbulence.
In some embodiments, the external air inlet 211 and the external air outlet 212 are provided with a first damper 213 and a second damper 214, respectively. In these embodiments, the control method of the present invention further includes:
when the air humidity in the ripening device 20 exceeds a preset maximum humidity threshold value, the first air door 213 and the second air door 214 are controlled to open the external air inlet 211 and the external air outlet 212 respectively; when the air humidity in the ripening device 20 is less than or equal to the preset maximum humidity, the first air door 213 and the second air door 214 are controlled to close the external air inlet 211 and the external air outlet 212 respectively.
That is, in other embodiments, the step S103 may further include: the first and second dampers 213 and 214 are controlled to open the external air inlet 211 and the external air outlet 212, respectively. The step S104 may further include: the first and second dampers 213 and 214 are controlled to close the external air inlet 211 and the external air outlet 212, respectively. Thus, generation of a cross taste or unnecessary airflow between the ripening device 20 and the refrigerating chamber 11 when the external circulation fan 27 is not required to be started can be prevented.
