Detailed ways

The present invention firstly provides a method for controlling a refrigerating and freezing device. 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 . Specifically, a refrigerating room, a freezing room and/or a temperature-changing room for storing articles may be defined inside the box body 10 . The refrigerating chamber, the freezing chamber and/or the temperature-changing chamber are selectively opened or closed through doors pivotably arranged on the front side of the box body 10 .

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 function of storing and keeping fresh in a traditional low-temperature environment, but also has a ripening function, which enriches the functions of the refrigerating and freezing device 1 .

Fig. 2 is a schematic sectional view taken along a horizontal sectional plane of the aging device according to an embodiment of the present invention. The ripening device 20 is defined with a ripening chamber 23 for placing the food to be ripened. The aging room 23 can be provided with a storage rack 26 for shelving the objects to be matured. There is a certain space above and below the storage grid 26, and the storage grid 26 is hollowed out to facilitate airflow while shelving on the storage grid 26. The upper and lower surfaces of the object to be matured are blown to ensure that both the upper surface and the lower surface of the object to be matured can be blown by the airflow evenly. 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.

Further, the ripening device 20 also includes a distance acquisition device 27 for acquiring the distance between the products to be aged contained in the ripening chamber 23 and each circumferential side wall of the ripening chamber 23 .

Fig. 3 is a schematic flowchart of a control method of a refrigerating and freezing device according to a first embodiment of the present invention. The control method of the refrigerating and freezing device of the present invention comprises:

Step S101, obtaining the distance between the product to be matured in the aging chamber 23 and each circumferential side wall of the aging chamber 23; and

Step S103 , when the distance between the object to be matured and any circumferential side wall of the aging chamber 23 is less than a preset minimum distance threshold, a prompt signal indicating that the object to be matured is too close to the wall of the aging chamber 23 is sent.

That is to say, the control method of the present invention judges whether the object to be matured is too close to the wall of the aging chamber 23 or even touches the wall of the aging chamber 23 by obtaining the distance between the object to be matured and each circumferential side wall of the aging chamber 23. risk, and remind the user that the food to be ripened is too close to the wall of the ripening chamber 23 by sending a prompt signal when the risk exists, so that the user can adjust the position of the food to be ripened in the ripening chamber 23 in a timely manner, thereby reducing the number of food to be ripened The probability of corruption due to touching the wall of the ripening chamber 23.

Specifically, the above prompt signal may be an acoustic signal, a light signal, other types of signals capable of reminding, or any combination of two or more signals.

However, the applicant realizes that it is not enough to send a prompt signal only when the object to be matured is too close to the wall of the aging chamber 23, and this risk cannot be prevented, and the user cannot know which part of the aging chamber 23 the object to be matured is far from. The circumferential side walls are too close to adjust blindly. Therefore, it would be better if the scene of the object to be ripened in the ripening chamber 23 can be observed. The applicant further realized that, based on the particularity of the ripening process, the ripening device 20 is usually closed, and its internal humidity requirements are relatively high, especially in the early stage of ripening, the food itself has a relatively high water content and a large amount of volatile moisture. The humidity in 20 can be as high as 90%. Therefore, if an imaging device or lighting device is installed in the ripening device 20 , the safety and stability of the imaging device or lighting device will be higher, and the cost will be higher. For this reason, the present application designs a control method of another embodiment.

Fig. 4 is a schematic flowchart of a control method of a refrigerating and freezing device according to a second embodiment of the present invention. In some embodiments, after acquiring the distance between the product to be ripened in the ripening chamber 23 and each circumferential side wall of the ripening chamber 23, the control method of the present invention further includes:

Step S1021, draw a simulated image according to the distance between the object to be matured and each circumferential side wall of the aging chamber 23, the simulated image includes the simulated figure of the product to be matured and the simulated figure of each circumferential side wall of the matured chamber 23, and The positional relationship between the simulated figure of the object to be matured and the simulated figure of each circumferential side wall of the aging chamber 23 is consistent with the actual positional relationship between the object to be matured and each circumferential side wall of the aging chamber 23; and

Step S1023 , outputting the above-mentioned simulation image on the display screen of the refrigerating and freezing device 1 .

That is to say, the present application also draws a simulated image according to the distance between the product to be matured and each circumferential side wall of the mature chamber 23 , and outputs the simulated image on the display screen of the refrigerating and freezing device 1 . Thus, the user can intuitively and clearly understand the actual positional relationship between the object to be matured and each circumferential side wall of the aging chamber 23 through the simulated image displayed on the display screen, so that the user can determine whether the object to be matured needs to be adjusted. The position, and the specific adjustment direction when the position needs to be adjusted, so that the user can accurately adjust the position of the object to be cooked according to the information displayed on the display screen, which improves the user experience.

Moreover, the present application uses the obtained distance to draw and display simulated images instead of displaying real images. There is no need to install imaging devices, lighting devices and other structures in the ripening chamber 23, which simplifies the structure of the ripening device 20 and reduces its cost.

It can be understood that the above-mentioned step S1021 and step S1023 are preferably before step S103, so as to play a better preventive role in advance.

Specifically, the positional relationship between the simulated figure of the object to be matured and the simulated figure of each circumferential side wall of the aging chamber 23 is consistent with the actual positional relationship between the object to be matured and each circumferential side wall of the matured chamber 23, which means What’s more, in the simulation image, the orientation of each circumferential side wall simulation figure relative to the simulated figure of the object to be matured is consistent with the actual orientation of each circumferential side wall relative to the object to be matured. In the simulation image, each circumferential side wall The distance relationship between the simulated figure and the edge of the simulated figure of the object to be matured is consistent with the actual distance between each circumferential side wall and the edge of the object to be matured.

In some embodiments, the drawn simulated image may be a two-dimensional planar image or a three-dimensional stereoscopic image. Regardless of whether it is a two-dimensional planar image or a three-dimensional stereoscopic image, the simulated image can be a simplified diagram including the simulated figure of the object to be matured and the simulated figure of each circumferential side wall of the ripening chamber 23 . For example, when the simulated image is a two-dimensional planar image, the simulated figure of the object to be matured can be a simple planar figure similar to the outer contour of the object to be matured, and the simulated figure of each circumferential side wall of the ripening chamber 23 can be able to represent each Lines for the approximate location of the circumferential sidewall. Therefore, on the basis of ensuring that the user can clearly see the positional relationship between the object to be matured and each circumferential side wall of the aging chamber 23, the difficulty of drawing the simulation graph is reduced, and the control logic and calculation process are simplified.

In some embodiments, the distance between the object to be matured and each circumferential side wall of the aging chamber 23 is the vertical distance from the edge of the object to be matured closest to the circumferential side wall to the circumferential side wall. That is to say, the present application specifically sets the distance between the object to be matured and each circumferential side wall of the aging chamber 23 as the minimum vertical distance between the object to be matured and the circumferential side wall. This is because the applicant realizes that the shape of the object to be matured may be irregular, resulting in that the distance between the edge of the object at different positions on the same side and the circumferential side wall of that side may be different. The present application only needs to judge the vertical distance between the edge of the object to be matured that is closest to the circumferential side wall and the peripheral side wall to effectively avoid edges at other positions of the object to be matured from being too close to the wall of the aging chamber 23 . In this way, the requirements for the distance acquisition device 27 can be reduced, and the number of distance acquisition devices 27 can be reduced.

Fig. 5 is a schematic flowchart of a control method for a refrigerating and freezing device according to a third embodiment of the present invention. In some embodiments, the control method of the present invention also includes:

Step S1022 , marking in the simulated image the minimum vertical distance between the edge of the simulated figure of the object to be matured and the simulated figure of each circumferential side wall of the ripening chamber 23 . Wherein, the minimum vertical distance between the edge of the simulated pattern of the object to be matured and the simulated pattern of each circumferential side wall of the aging chamber 23 is equal to the distance from the acquired edge of the object to be matured that is closest to the circumferential side wall to the circumference. Vertical distance to the side wall.

That is to say, the vertical distance from the edge of the object to be matured that is closest to a certain circumferential side wall to the circumferential side wall can be marked in the simulation image, and marked as the edge of the simulated figure of the object to be matured and the matured object. The minimum vertical distance between the simulated graphics of each circumferential side wall of the chamber 23 is used to facilitate the user to more intuitively obtain the actual distance information between the edge of the object to be matured and the wall surface of the aging chamber 23 .

It can be understood that the above step S1022 may be after step S1021 and before step S1023.

In some embodiments, the control method of the present invention also includes:

When the distance between the ripened product and any circumferential sidewall of the aging chamber 23 is less than the preset minimum distance threshold, the sign of the minimum vertical distance marked in the flashing simulation image that is less than the preset minimum distance threshold is displayed on the display screen.

That is to say, the user can be conspicuously reminded that the food to be ripened is too close to the wall of the ripening chamber 23 by flashing, and can quickly judge which circumferential side wall of the ripening chamber 23 is too far away from the distance mark blinking in the simulation image. It is convenient for the user to quickly and accurately adjust the position of the food to be matured.

Specifically, this step can be performed together with the above-mentioned step S103, that is, sending out a prompt signal and blinking a distance mark at the same time. In some alternative embodiments, it is also possible to first send out a prompt signal and then flash the distance mark, or to flash the distance mark first and then send out the prompt signal.

Fig. 6 is a schematic flowchart of a control method of a refrigerating and freezing device according to a fourth embodiment of the present invention. In other embodiments, the control method of the present invention also includes:

Step S1021', acquiring actual image information in the ripening chamber 23; and

Step S1022', output actual image information on the display screen of the refrigerating and freezing device 1.

Wherein, the actual image information acquired in step S1021' includes at least the image of the object to be matured and the lower image of each circumferential side wall of the aging chamber 23, so that the user can observe the object to be matured and each circumferential side wall of the aging chamber 23 the distance between.

Likewise, the above-mentioned steps S1021' and S1022' are preferably before step S103, so as to have a better preventive effect in advance.

Further, the above actual image information can be obtained through the camera device 28 installed in the ripening chamber 23 . The camera device 28 can be a camera with a light source and better waterproof and moisture-proof performance.

Preferably, the camera device 28 can be arranged at the center of the top of the aging chamber 23, so as to comprehensively capture the images of the object to be matured and each circumferential side wall of the aging chamber 23, and avoid blind spots.

Further, the distance between the object to be matured and each circumferential side wall of the aging chamber 23 can be obtained by a plurality of distance sensors arranged in the aging chamber 23 around the object to be matured. Specifically, the distance sensor may be an infrared ranging sensor, a radar ranging sensor or other suitable ranging sensors. The distance sensors can be evenly distributed around the food to be matured.

The present invention also provides a refrigerating and freezing device, and FIG. 7 is a schematic structural block diagram of the refrigerating and freezing device according to an embodiment of the present invention. Referring to FIG. 1 and FIG. 7 , the refrigerating and freezing device 1 of the present invention includes a cabinet 10 , a ripening device 20 and a control device 30 .

The ripening device 20 is arranged in the box body 10, and defines a ripening chamber for placing the food to be ripened therein. The ripening device 20 includes a distance acquiring device 27 for acquiring the distance between the product to be ripened and each circumferential side wall of the ripening chamber 23 . The control device 30 includes a processor 31 and a memory 32, the memory 32 stores a machine executable program 33, and the machine executable program 33 is used to implement the control method described in any of the above embodiments when executed by the processor 31.

Specifically, the processor 31 may be a central processing unit (central processing unit, CPU for short), or a digital processing unit or the like. The processor 31 sends and receives data through the communication interface. The memory 32 is used to store programs executed by the processor 31 . The memory 32 is any medium that can be used to carry or store desired program codes in the form of instructions or data structures and can be accessed by a computer, and can also be a combination of multiple memories. The above-mentioned machine-executable program 33 can be downloaded from a computer-readable storage medium to a corresponding computing/processing device or downloaded to a computer or an external storage device via a network (such as the Internet, a local area network, a wide area network, and/or a wireless network).

Fig. 8 is a schematic sectional view taken along a vertical sectional plane of the aging device according to an embodiment of the present invention. In some embodiments, the aging device 20 includes an outer casing 21 , an inner casing 22 and a circulation fan 25 disposed in the outer casing 21 , and the aging chamber 23 is formed in the inner casing 22 . 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 extending longitudinally. The longitudinal direction here means the longitudinal direction of the inner case 22 and the outer case 21 and is perpendicular to the transverse direction thereof.

Fig. 9 is a schematic diagram of the air flow path in the aging device according to an embodiment of the present invention. Further, the air supply channel 24 communicates with the aging chamber 23 through the air supply ports 222 provided on the two lateral side plates 221 of the inner casing 22, and the circulation fan 25 is used to drive the airflow in the outer casing 21 to flow between the air supply channel 24 and Circulation flows between the aging chambers 23 . That is to say, the ripening device 20 has a two-layer structure of an inner casing 22 and an outer casing 21 . Driven by the circulating fan 25 , the airflow in the two air supply passages 24 is respectively sent to the aging chamber 23 through the air supply ports 222 provided on the two lateral side plates 221 of the inner casing 22 . That is to say, the air flow flows into the aging chamber 23 from two lateral sides of the aging chamber 23 simultaneously, which improves the uniformity of air supply in the lateral direction of the aging chamber 23, thereby improving the aging effect of the food to be aged.

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 . Thereby, the uniformity of air supply at various places in the height direction of the aging chamber 23 can be improved, thereby ensuring that the upper surface and the lower surface of the object to be matured have a uniform airflow blowing effect, and the aging effect of the object to be matured is improved.

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 realized that the same circulation fan 25 is used to simultaneously drive the airflow in the two air supply ducts 24 to flow to the aging chamber 23 , and the circulation fan 25 must be located upstream of the two air supply ducts 24 . Therefore, in the flow direction of the airflow in the air supply duct 24 (that is, 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 duct 24 decreases gradually in the airflow direction can be compensated for by increasing the arrangement density of the airflow ports 222, thereby improving the uniformity of airflow in the longitudinal direction of the aging chamber 23. 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 aging effect of the object to be matured is improved.

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 can be obtained in the horizontal direction, the height direction and the vertical direction of the ripening object, and the aging effect of the ripening object is better. .

In some embodiments, an end plate 223 between the two lateral side plates 221 of the inner shell 22 is provided with an air return port 224 for allowing the air in the aging chamber 23 to flow to the outside of the inner shell 22 . The circulation fan 25 is arranged between the outer casing 21 and the inner casing 22 , and the airflow inlet of the circulation fan 25 communicates with the air return port 224 , and the airflow outlet of the circulation fan 25 communicates with the two air supply channels 24 .

As a result, the airflow flowing into the aging chamber 23 can flow through a longer path in the aging chamber 23 and then flow out from the air return port 224, and the airflow blows the surface of the ripening object for a longer time, fully exerting the airflow to dry the aging object. effect.

In some embodiments, the air return port 224 is opened on the rear end plate of the inner shell 22 at the rear side of the box body 10 , and the circulation fan 25 is fixed on the outside of the rear end plate.
