Detailed Description
The present invention first provides a control method of a refrigerating and freezing apparatus, and fig. 1 is a schematic structural diagram 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. Specifically, the case 10 may define therein a refrigerating compartment, a freezing compartment, and/or a temperature changing compartment for storing articles. The refrigerating chamber, the freezing chamber and/or the temperature varying chamber are selectively opened or closed by a door 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 is a schematic cross-sectional view of a ripening apparatus according to one embodiment of the present invention, taken along a horizontal cross-section. The ripening device 20 defines therein a ripening chamber 23 for placing the to-be-ripened substance. The ripening chamber 23 may be provided with a rack 26 for holding the to-be-cooked object, and a certain space is provided above and below the rack 26, and the rack 26 is hollowed out, so that air flow can blow the upper and lower surfaces of the to-be-cooked object placed on the rack 26 at the same time, thereby ensuring that the upper and lower surfaces of the to-be-cooked object can uniformly receive air flow. 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.
Further, the ripening device 20 further comprises distance acquiring means 27 for acquiring the distance between the to-be-ripened substance accommodated in the ripening chamber 23 and each circumferential side wall of the ripening chamber 23.
Fig. 3 is a schematic flow chart of a control method of a refrigerating and freezing apparatus according to a first embodiment of the present invention. The control method of the refrigeration and freezing device of the invention comprises the following steps:
step S101, obtaining the distance between the to-be-cooked object in the ripening chamber 23 and each circumferential side wall of the ripening chamber 23; and
step S103, when the distance between the to-be-cooked object and any circumferential side wall of the ripening chamber 23 is smaller than the preset minimum distance threshold, a prompt signal for indicating that the to-be-cooked object is too close to the wall surface of the ripening chamber 23 is sent out.
That is, the control method of the present invention judges whether there is a risk of approaching the wall of the ripening chamber 23 or even touching the wall of the ripening chamber 23 by obtaining the distance between the ripening object and each circumferential side wall of the ripening chamber 23, and when there is the risk, alerts the user that the ripening object is approaching the wall of the ripening chamber 23 by sending out the alert signal, so that the user and the field can conveniently adjust the position of the ripening object in the ripening chamber 23, thereby reducing the probability of spoilage of the ripening object due to touching the wall of the ripening chamber 23.
Specifically, the prompting signal may be an acoustic signal, an optical signal, other types of signals capable of playing a role in prompting, or a combination of any two or more signals.
However, the applicant has realized that it is not sufficient to give a warning signal only when the object to be matured is too close to the wall of the maturing chamber 23, that this risk cannot be prevented, and that the user cannot know which circumferential side wall of the maturing chamber 23 is too close to the bottom, so that adjustment is blind. Therefore, if a scene of the to-be-matured object in the maturing chamber 23 can be observed better. The applicant has further appreciated that, based on the particularities of the ripening process, the ripening device 20 is generally closed and the humidity inside it is high, especially in the early stages of ripening, the food itself is high in water content, the volatile water content is high, and the humidity inside the ripening device 20 can be as high as more than 90%. Therefore, if the imaging device or the lighting device is provided in the curing device 20, the safety and stability of the imaging device or the lighting device are required to be high, and the cost is also high. For this purpose, the present application contemplates a control method of another embodiment.
Fig. 4 is a schematic flow chart of a control method of a refrigerating and freezing apparatus according to a second embodiment of the present invention. In some embodiments, after obtaining the distance between the to-be-matured in the maturing chamber 23 and each circumferential side wall of the maturing chamber 23, the control method of the present invention further includes:
step S1021, drawing a simulation image according to the distance between the to-be-cooked object and each circumferential side wall of the ripening chamber 23, wherein the simulation image comprises a simulation pattern of the to-be-cooked object and a simulation pattern of each circumferential side wall of the ripening chamber 23, and the position relationship between the simulation pattern of the to-be-cooked object and the simulation pattern of each circumferential side wall of the ripening chamber 23 is consistent with the actual position relationship between the to-be-cooked object and each circumferential side wall of the ripening chamber 23; and
step S1023, outputting the simulation image on the display screen of the refrigeration and freezing device 1.
That is, the present application also draws a simulation image according to the distance between the to-be-matured object and each circumferential side wall of the maturing chamber 23, and outputs the simulation image on the display screen of the refrigerating and freezing apparatus 1. Therefore, the user can intuitively and clearly know the actual position relationship between the to-be-cooked object and each circumferential side wall of the ripening chamber 23 through the simulation image displayed on the display screen, so that the user can conveniently determine whether the to-be-cooked object needs to be adjusted in position and the specific adjustment direction when the to-be-cooked object needs to be adjusted in position, the user can accurately adjust the position of the to-be-cooked object according to the information displayed on the display screen, and the use experience of the user is improved.
In addition, the present application draws and displays the analog image by the acquired distance, instead of displaying the real image, and does not require the configuration of an imaging device, an illumination device, and the like in the ripening room 23, thereby simplifying the configuration of the ripening device 20 and reducing the cost thereof.
It will be appreciated that steps S1021 and S1023 described above are preferably prior to step S103 in order to provide a better early preventative effect.
Specifically, the positional relationship between the simulated pattern of the to-be-cooked object and the simulated pattern of each circumferential side wall of the cooking chamber 23 coincides with the actual positional relationship between the to-be-cooked object and each circumferential side wall of the cooking chamber 23, meaning that the orientation of each circumferential side wall simulated pattern with respect to the to-be-cooked object coincides with the actual orientation of each circumferential side wall with respect to the to-be-cooked object in the simulated image, and the distance magnitude relationship between each circumferential side wall simulated pattern and the edge of the to-be-cooked object coincides with the actual distance magnitude relationship between each circumferential side wall and the edge of the to-be-cooked object in the simulated image.
In some embodiments, the drawn analog image may be a two-dimensional planar image or a three-dimensional stereoscopic image. The simulation image may be a schematic diagram including a simulation pattern of the to-be-matured object and a simulation pattern of each circumferential side wall of the maturing chamber 23, whether it is a two-dimensional plane image or a three-dimensional stereoscopic image. For example, when the simulated image is a two-dimensional planar image, the simulated pattern of the to-be-cooked object may be a simple planar pattern similar to the outer contour of the to-be-cooked object, and the simulated pattern of each circumferential side wall of the cooking chamber 23 may be a line capable of representing the approximate position of each circumferential side wall. Therefore, on the basis of ensuring that a user can clearly and definitely see the position relationship between the to-be-cooked object and each circumferential side wall of the ripening chamber 23, the drawing difficulty of the simulation graph is reduced, and the control logic and the calculation process are simplified.
In some embodiments, the distance between the to-be-cooked object and each circumferential side wall of the ripening chamber 23 is the vertical distance of the edge of the to-be-cooked object closest to the circumferential side wall from the circumferential side wall. That is, the present application sets the distance between the to-be-cooked object and each circumferential side wall of the ripening chamber 23 specifically to the minimum vertical distance between the to-be-cooked object and the circumferential side wall. This is because the applicant has appreciated that the appearance of the to-be-cooked object may be irregular, resulting in that the distance between the edge of the to-be-cooked object at different positions on the same side and the circumferential side wall of that side may be different. The method and the device can effectively avoid the situation that the edge of the other position of the to-be-cooked object is too close to the wall surface of the ripening chamber 23 only by judging the vertical distance between the edge of the to-be-cooked object closest to the circumferential side wall and the circumferential side wall. Thereby, the requirements for the distance acquiring devices 27 can be reduced, and the number of distance acquiring devices 27 can be reduced.
Fig. 5 is a schematic flow chart of a control method of a refrigerating and freezing apparatus according to a third embodiment of the present invention. In some embodiments, the control method of the present invention further comprises:
in step S1022, the minimum vertical distance between the edge of the simulated pattern of the to-be-matured object and the simulated pattern of each circumferential side wall of the maturing chamber 23 is marked in the simulated image. Wherein the minimum vertical distance between the edge of the simulated pattern of the to-be-cooked object and the simulated pattern of each circumferential side wall of the cooking chamber 23 is equal to the acquired vertical distance of the edge closest to the circumferential side wall of the to-be-cooked object from the circumferential side wall.
That is, the vertical distance of the edge of the actually obtained to-be-cooked object closest to a certain circumferential side wall from the circumferential side wall may be marked in the simulation image and as the minimum vertical distance between the edge of the to-be-cooked object simulation pattern and each circumferential side wall simulation pattern of the ripening chamber 23, so that the user can more intuitively obtain the actual distance information between the edge of the to-be-cooked object and the wall surface of the ripening chamber 23.
It is understood that the step S1022 may be performed after the step S1021 and before the step S1023.
In some embodiments, the control method of the present invention further comprises:
and when the distance between the to-be-cooked object and any circumferential side wall of the ripening chamber 23 is smaller than a preset minimum distance threshold value, flashing the mark of the minimum vertical distance smaller than the preset minimum distance threshold value marked in the simulated image on the display screen.
That is, the user can be reminded of the fact that the object to be matured is too close to the wall surface of the maturing chamber 23 in a flashing manner, and the distance between the object to be matured and the circumferential side wall of the maturing chamber 23 can be judged rapidly and accurately by means of the flashing distance mark in the simulation image, so that the user can adjust the position of the object to be matured rapidly and accurately.
Specifically, this step may be performed together with the above step S103, i.e., the prompt signal and the blinking distance identification are issued at the same time. In some alternative embodiments, the prompt signal may be sent out first and then the distance identifier may be flashed, or the prompt signal may be sent out first and then the distance identifier may be flashed.
Fig. 6 is a schematic flow chart of a control method of a refrigerating and freezing apparatus according to a fourth embodiment of the present invention. In other embodiments, the control method of the present invention further comprises:
step S1021', obtaining the actual image information in the ripening room 23; and
step S1022' outputs actual image information on the display screen of the refrigerating and freezing apparatus 1.
The actual image information obtained in step S1021' includes at least an image of the to-be-cooked object and a lower image of each circumferential side wall of the cooking chamber 23, so that the user can observe the distance between the to-be-cooked object and each circumferential side wall of the cooking chamber 23.
Likewise, the above steps S1021 and S1023 are preferably before step S103 in order to provide a better early prevention effect.
Further, the above-mentioned actual image information may be obtained by an image pickup device 28 provided in the ripening room 23. The camera device 28 may be a camera with a light source and good waterproof and moistureproof performances.
Preferably, the image pickup device 28 may be disposed at the center of the top of the ripening chamber 23 so as to comprehensively acquire images of the to-be-ripened objects and the respective circumferential side walls of the ripening chamber 23, avoiding dead corners.
Further, the distance between the to-be-cooked object and each circumferential side wall of the ripening chamber 23 may be obtained by a plurality of distance sensors disposed around the to-be-cooked object within the ripening chamber 23. In particular, the distance sensor may be an infrared distance sensor, a radar distance sensor or other suitable distance sensor. The distance sensors may be uniformly distributed around the object to be cooked.
The present invention also provides a refrigerating and freezing apparatus, and fig. 7 is a schematic block diagram of a refrigerating and freezing apparatus according to an embodiment of the present invention. Referring to fig. 1 and 7, the refrigerating and freezing apparatus 1 of the present invention includes a cabinet 10, a ripening apparatus 20, and a control apparatus 30.
The ripening device 20 is disposed in the case 10, and defines a ripening chamber therein for placing the to-be-ripened objects.

Fig. 8 is a schematic cross-sectional view of a ripening apparatus according to one embodiment of the present invention taken along a vertical cross-section. In some embodiments, the ripening device 20 includes an outer casing 21, and an inner casing 22 and a circulation fan 25 provided inside the outer casing 21, and the ripening chamber 23 is formed in the inner casing 22. The lateral sides of the inner case 22 are spaced apart from the lateral sides of the outer case 21, respectively, to form two air supply passages 24 extending in the longitudinal direction. The longitudinal direction herein means the longitudinal direction of the inner case 22 and the outer case 21 and is perpendicular thereto in the transverse direction.
Fig. 9 is a schematic view of the airflow path in the ripening apparatus according to one embodiment of the present invention. Further, the air supply passage 24 communicates with the curing chamber 23 through air supply openings 222 provided in both lateral side plates 221 of the inner casing 22, and the circulation fan 25 is for driving the air flow in the outer casing 21 to circulate between the air supply passage 24 and the curing chamber 23. That is, the curing device 20 has a two-layer structure of an inner case 22 and an outer case 21. The air flows in the two air supply channels 24 are respectively sent to the curing chamber 23 through air supply openings 222 formed in two lateral side plates 221 of the inner casing 22 under the driving of the circulating fan 25. That is, the air flow simultaneously flows into the ripening chamber 23 from both lateral sides of the ripening chamber 23, 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 substance.
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, thereby ensuring that the upper and lower surfaces of the to-be-ripened object have a uniform air flow blowing effect, and improving the ripening effect of the to-be-ripened object.
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 realized that the air flow in the two supply air ducts 24 is driven simultaneously to the ripening chamber 23 by the same circulation fan 25, and that the circulation fan 25 is necessarily located upstream of the two supply air ducts 24. Accordingly, the flow velocity of the air flow gradually decreases in the air flow direction in the air supply duct 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 duct 24 decreases in the airflow flowing direction can be overcome by increasing the arrangement density of the air supply openings 222, the air supply uniformity of the ripening chamber 23 in the longitudinal direction is improved, the uniform airflow blowing effect of the surface areas of the to-be-cooked object in the longitudinal direction is ensured, and the ripening effect of the to-be-cooked object is improved.
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 supply passage 24 increases stepwise. 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 in the transverse direction, the height direction and the longitudinal direction, and the to-be-cooked object has good curing effect.
In some embodiments, the end plate 223 of the inner casing 22 connected between the two lateral side plates 221 thereof is provided with an air return port 224 for the air flow in the curing chamber 23 to the outside of the inner casing 22. The circulating fan 25 is disposed between the outer casing 21 and the inner casing 22, and an air flow inlet of the circulating fan 25 is communicated with the return air inlet 224, and an air flow outlet of the circulating fan 25 is communicated with the two air supply channels 24.
Thus, the air flow flowing into the ripening chamber 23 can flow out from the air return port 224 after flowing through a longer path in the ripening chamber 23, the blowing time of the air flow on the surface of the to-be-ripened object is longer, and the air drying effect of the air flow on the to-be-ripened object is fully exerted.
In some embodiments, the return air port 224 is formed in a rear end plate of the inner casing 22 at the rear side of the casing 10, and the circulation fan 25 is fixed to the outer side of the rear end plate. That is, when the curing device 20 is placed in the case 10, the circulation fan 25 is positioned at the rear side of the case 10, and the user does not easily feel noise generated when the circulation fan 25 is operated.
In some embodiments, the circulation fan 25 is a centrifugal fan with unidirectional air intake and bidirectional air outlet. Therefore, not only the air flow of the air return port 224 can be blown to the two air supply channels 24 respectively towards two opposite directions, but also the space occupied by the circulating fan 25 is reduced, so that the ripening device 20 has a more compact structure and a smaller volume, and thus, the occupation of excessive space in the box 10 is avoided.
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, a refrigerator compartment 11 for storing articles is defined in the case 10, and a ripening device 20 is provided in the refrigerator compartment 11. The storage temperature of the refrigerating chamber 11 is usually in the range of 0 to 8 ℃, and is suitable for the requirements of the to-be-cooked object on the ripening temperature.

Even if the humidity in the ripening device 20 is not proper, it is convenient to adjust by the air flow in the refrigerating chamber 11. Therefore, the ripening device 20 is provided in the refrigerating chamber 11, so that the temperature and humidity conditions of the refrigerating chamber 11 itself can be fully utilized, and the cost can be reduced to the maximum extent.
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.
