The following description of the embodiments of the present invention will be made with reference to the accompanying drawings, in which it is apparent that the embodiments described below are some, but not all embodiments of the invention.
A fresh-keeping apparatus 100 according to an embodiment of the present invention is described with reference to fig. 1 to 3, and is applicable to a refrigeration device such as a refrigerator, a freezer, and the like, and the fresh-keeping apparatus 100 will be described with specific examples.
Referring to fig. 1, the fresh-keeping device 100 provided by the embodiment of the invention comprises a storage container 110, wherein the storage container comprises a frame 112 and a drawer 111, an accommodating space 113 is arranged in the frame 112, an opening matched with the drawer 111 is formed in one side of the frame 112, the drawer 111 can enter the accommodating space 113 through the opening, so that the drawer 111 and the frame 112 are matched to form a closed space, and food materials such as fruits and vegetables can be stored conveniently.
It may be appreciated that the storage container 110 is provided with the illumination module 120 and the oxygen removal module 130, where the illumination module 120 is used to provide illumination for the food material in the storage container 110, and the oxygen removal module 130 is used to replace oxygen in the storage container 110 outside the storage container 110, so that a low oxygen environment can be formed in the storage container 110, and thus the functions of illumination and cultivation and low oxygen fresh keeping are combined together.
Referring to fig. 1, specifically, the illumination module 120 and the deoxidizing module 130 are installed at the top of the frame 112, and an opening corresponding to the illumination module 120 may be provided at the top of the frame 112, so that the light emitted by the illumination module 120 may illuminate the food in the drawer 111. Set up the bleeder vent at the top of frame 112, bleeder vent and accommodation space 113 intercommunication, the department at the bleeder vent is installed to deoxidization module 130, and the oxygen accessible bleeder vent in the accommodation space 113 gets into deoxidization module 130, can displace accommodation space 113's oxygen to accommodation space 113 outside through deoxidization module 130, reduces accommodation space 113's oxygen content to make accommodation space 113 form the hypoxic environment. It should be noted that, the oxygen removal module 130 is not limited to be installed on the frame 112, and taking a refrigerator as an example, the oxygen removal module 130 may also be installed on a body of the refrigerator, so that the oxygen removal module 130 is kept in communication with the inside of the accommodating space 113 through the air holes.
It can be understood that when the light waves generated by the illumination module 120 are used for illuminating the food materials, the gene expression and the key enzyme activity for nutrient synthesis in the metabolic pathway of the fruits and vegetables can be regulated and controlled, so that the content of functional active substances in the fruits and vegetables is increased, and the effect of increasing the nutrition of the food materials is achieved; the deoxidization module 130 is used for forming a low-oxygen environment in the accommodating space 113, so that the aerobic respiration of fruits and vegetables can be inhibited under the low-oxygen environment, the consumption of organic matters such as sugar and the like can be reduced, and the preservation period of the fruits and vegetables can be prolonged. In addition, the low-oxygen environment can also effectively inhibit the breeding of aerobic bacteria and anaerobic bacteria, prevent microorganisms from putrefactive fruits and vegetables, inhibit the activity of certain enzymes, inhibit the production of ethylene, delay the after-ripening and aging processes, and be beneficial to keeping the nutrition and freshness of fruits and vegetables.
It should be noted that, in the embodiment, the frame 112 and the drawer 111 may be installed in a refrigerating chamber of a refrigerator, and by integrating the functions of light raising and low oxygen preservation on the preservation device 100, food materials such as fruits and vegetables may be directly stored in the drawer 111 during use. Considering that the low-oxygen environment is suitable for storing food materials for a long time, the drawer 111 can be deoxygenated through the deoxygenation module 130, the oxygen concentration in the drawer 111 is reduced, the illumination module 120 is started to illuminate the food materials in the low-oxygen environment, the negative effects of increasing the opening degree of plant air holes, accelerating the respiration and transpiration, shortening the fresh-keeping period and the like caused by illumination can be effectively reduced in the low-oxygen environment while the content of the fruit and vegetable nutrients is improved, that is, the content of the fruit and vegetable nutrients can be improved, the fresh-keeping period of fruits and vegetables can be prolonged, and the requirements of consumers on the fruit and vegetable nutrients and the fresh-keeping period can be met.
In the embodiment, the operation process of the deoxidizing module 130 and the illumination module 120 is controlled by a controller, specifically, the controller controls the deoxidizing module 130 to operate first to deoxidize, so that the oxygen concentration in the drawer 111 reaches the level of the low-oxygen environment, and then controls the illumination module 120 to be started for illumination.
It should be noted that, the fresh-keeping device 100 can detect the oxygen concentration in the drawer 111 in real time through an oxygen concentration sensor (not shown in the drawings), and the controller obtains the oxygen concentration data detected by the oxygen concentration sensor, determines whether the oxygen concentration reaches the low oxygen environment according to the oxygen concentration, and controls the lighting module 120 to be turned on after the oxygen concentration reaches the low oxygen environment. In addition, considering that the high humidity environment is advantageous to suppress the transpiration of food materials, the fresh keeping device 100 further detects the humidity in the drawer 111 through a humidity sensor (not shown in the drawings), and the controller may control the illumination module 120 according to the oxygen concentration and the humidity, thereby further improving the fresh keeping effect.
It will be appreciated that the oxygen removal module 130 performs an oxygen removal process in the drawer 111, and a certain time is required to reach a low oxygen environment, and in some embodiments, the controller may determine the oxygen removal time according to the oxygen removal rate of the oxygen removal module 130 and the volume of the drawer 111, and control the lighting module 120 to be turned on according to the oxygen removal time. That is, when the deoxidizing module 130 works for a set time, the controller controls the illumination module 120 to be turned on for illumination.
It should be noted that, the oxygen output rate of the oxygen removal module 130 may be determined by a factory test, for example, for the 20L drawer 111, the oxygen concentration after 1, 2, and 3 hours of oxygen removal may be obtained by the test, so as to obtain the oxygen removal rate. It is understood that when the drawer 111 is opened, the oxygen concentration in the drawer 111 can reach about 20%, and the time required for reaching a low oxygen environment with a certain concentration can be calculated according to the oxygen reduction speed, that is, the oxygen removal time can be determined. Thus, after the drawer 111 is opened and closed again, the deoxygenation module 130 is operated to start the illumination module when the deoxygenation time is reached, so as to achieve the purposes of illumination and cultivation increase and fresh keeping.
Referring to fig. 2, in some embodiments, the illumination module 120 includes an LED lamp, and a controller is connected to the LED lamp, through which the illumination intensity and the switching time of the LED lamp can be controlled. It can be understood that specific illumination intensity is matched for different food materials, so that accumulation of functional active ingredients in fruits and vegetables is facilitated, and the nutritional value of the fruits and vegetables can be improved in a short time.
Considering that the promotion effect can reach the limit after illumination reaches a certain time, further illumination can not continue to promote the accumulation of functional active ingredients, but quality decay can be easily caused, therefore, the controller can adjust the starting time of the LED lamp, and the illumination module 120 is closed and illumination is stopped after the illumination reaches a preset time, so that fruits and vegetables can maintain the level of high functional active substances, and decay acceleration caused by illumination is avoided; meanwhile, the fresh-keeping agent is matched with the fresh-keeping agent to be kept in a low-oxygen environment, so that the aim of prolonging the fresh-keeping period is fulfilled.
It should be noted that, the LED lamp that the embodiment adopted is the blue light LED lamp, and the blue light wave is favorable to promoting the accumulation of berry anthocyanin, is applicable to berry food material, and the controller can match specific blue light illumination intensity to shine at preset time, thereby can effectively improve anthocyanin content and synthase activity.
In some embodiments, the LED lamp may be a red LED lamp, which may be advantageous to increase chlorophyll and carotenoid content of the green vegetables. Specifically, different colored lights can be selected according to the types of food materials, corresponding illumination intensity and illumination time are matched, the content of functional active substances in fruits and vegetables is rapidly improved, and a user can eat fruits and vegetables with higher nutrition in a short time.
It should be noted that, the LED lamp of the embodiment includes a lamp bead and a lamp cap (not shown in the drawing), the lamp cap cover is disposed on the lamp bead, the lamp bead and the lamp cap are mounted on the top of the frame 112 through the metal plate, the lamp cap has a light reflection function, so that the light emitted by the lamp bead can be concentrated and irradiated to the inner side of the drawer 111, and the light utilization rate is improved. The number of the lamp beads can be set according to practical application requirements, and the number of the lamp beads is not limited.
Referring to fig. 2 and 3, the oxygen removing module 130 is installed at the top of the outside of the frame 112, and the oxygen removing module 130 is based on the electrochemical reduction principle, also called electrochemical oxygen removing module 130, to displace oxygen in the accommodating space 113 to the external space through the electrolytic reduction reaction, thereby maintaining the accommodating space 113 in a state of low oxygen concentration.
Specifically, the deoxidizing module 130 includes a liquid storage box 131, the liquid storage box 131 is mounted at the top of the frame 112, the liquid storage box 131 is loaded with electrolyte, two electrodes are further arranged in the liquid storage box 131, the two electrodes are an anode and a cathode (not shown in the drawing), a waterproof breathable film is arranged on one side of the liquid storage box 131 facing the storage container 110, the waterproof breathable film is arranged at an air vent of the frame 112, the deoxidizing module 130 can be in contact with air in the accommodating space 113 through the waterproof breathable film, the cathode is arranged on the waterproof breathable film, and the anode is a metal nickel screen.
The working principle of the deaeration module 130 is that oxygen in the drawer 111 enters the liquid storage box 131 through a waterproof and breathable film, and the oxygen entering the liquid storage box 131 passes through the cathodeElectrochemical reduction to OH-and/or HO 2 OH-and/or HO 2 Diffusion into the anode in the electrolyte produces O by oxidation reaction 2 The method comprises the steps of carrying out a first treatment on the surface of the O produced by anode 2 And then discharged to the external space through the air outlet, so that the oxygen concentration in the drawer 111 can be reduced.
It should be noted that, the oxygen removal module 130 is completed based on electrochemical reaction during the oxygen removal process, the oxygen removal module 130 only reacts with oxygen, and the oxygen removed by the oxygen removal module 130 can be directly discharged to the outside of the drawer 111 or discharged to the outside of the refrigerator through an exhaust pipe. Compared with the mode of pumping air by adopting a vacuum pump to obtain a low-oxygen environment, the fresh-keeping device 100 provided by the embodiment of the invention has the characteristics of low noise and low cost, and is more practical and reliable.
A freshness-preserving control method according to an embodiment of the present invention, which is applicable to, but not limited to, the freshness-preserving apparatus 100 shown in the above-described embodiment, will be described below with specific examples.
Referring to fig. 4, the fresh-keeping control method of the embodiment includes, but is not limited to, the following steps:
step S100, controlling the operation of the deoxidizing module to enable a low-oxygen environment to be formed in the storage container;
step S200, when the oxygen concentration in the storage container is lower than a first preset value, the illumination module is controlled to be started to illuminate the food materials, and the illumination module is controlled to be closed after the preset time.
It will be appreciated that, in the above-described preservation apparatus 100 according to the above-described embodiment of the preservation control method, the specific structure of the preservation apparatus 100 may refer to the structure of the embodiment shown in fig. 1 to 5, and the specific control process may be performed by the control apparatus of the refrigerator. The storage container 110 includes a frame 112 and a drawer 111 disposed in the refrigerator, and after food is placed in the drawer 111, the operation of the oxygen removal module 130 is controlled, oxygen in the drawer 111 is discharged to an external space through the oxygen removal module 130, the oxygen content in the drawer 111 is reduced, and as the oxygen removal module 130 continuously discharges oxygen, the oxygen concentration in the drawer 111 is gradually reduced, thereby forming a low oxygen environment in the drawer 111.
Considering that the oxygen concentration is lower than a certain range, the oxygen respiration of fruits and vegetables can be inhibited, the consumption of organic matters such as sugar is reduced, and the purpose of prolonging the fresh-keeping period of the fruits and vegetables is achieved, the fresh-keeping device 100 of the embodiment can detect the oxygen concentration in the drawer 111 in real time through the oxygen concentration sensor, and the fresh-keeping device 100 can be controlled to accurately achieve a low-oxygen environment. In addition, the low-oxygen environment can also effectively inhibit the breeding of aerobic bacteria and anaerobic bacteria, prevent microorganisms from putrefactive fruits and vegetables, inhibit the activity of certain enzymes, inhibit the production of ethylene, delay the after-ripening and aging processes, and be beneficial to keeping the nutrition and freshness of fruits and vegetables.
In step S200, when the oxygen concentration in the drawer 111 is lower than the first preset value, the illumination module 120 is controlled to be turned on, and the illumination module 120 irradiates the food materials in the drawer 111, so that the generated light wave can regulate and control the gene expression and the activity of key enzymes for synthesizing nutrients in the metabolic pathway of the fruits and vegetables, and effectively improve the content of functional active ingredients in the fruits and vegetables, thereby being beneficial to quickly improving the nutrition level of the food materials. Considering that the effect of illumination on promoting food nutrient accumulation has a certain limit, in the embodiment, when illumination reaches a preset time, the illumination module 120 is controlled to stop illumination, so that fruits and vegetables can keep high levels of functional active ingredients, and the condition of decay acceleration caused by overlong illumination is reduced.
It can be understood that by controlling the illumination in the low-oxygen environment, the low-oxygen environment can effectively reduce the negative effects of plant pore opening increase, respiration and transpiration acceleration, fresh-keeping period shortening and the like caused by the illumination while improving the content of the nutrients of the fruits and the vegetables, so that the combination of the illumination raising and low-oxygen fresh-keeping functions is realized based on the control method, the content of the nutrients of the fruits and the vegetables can be improved, the fresh-keeping period of the fruits and the vegetables can be prolonged, and the requirements of consumers on the nutrients and the fresh-keeping period of the fruits and the vegetables can be met.
In some embodiments, the deoxidizing module 130 performs deoxidizing treatment in the drawer 111, and a certain time is required to reach the oxygen concentration to reach the low-oxygen environment, so that the deoxidizing time can be determined according to the deoxidizing rate of the deoxidizing module 130 and the volume of the drawer 111, and the illumination module 120 is controlled to be turned on according to the deoxidizing time, that is, when the deoxidizing module 130 works for a set time, the illumination module 120 is controlled to be turned on to illuminate, so that the purposes of illumination raising and low-oxygen fresh keeping are achieved.
The control method in the embodiment sets the first preset value of the oxygen concentration to 5%, and the preset time for which the illumination module 120 is turned on is 2 hours, that is, when the oxygen concentration in the drawer 111 is lower than 5%, the illumination module 120 is controlled to be turned on, and after 2 hours of illumination passes, the illumination module 120 is controlled to be turned off.
It can be understood that different illumination time can be set according to different types of food materials, so that the nutrient content of the food materials can reach a better level, and the accumulation of functional active ingredients affecting the food materials due to overlong or too short illumination time can be reduced. For example, the illumination time may be 1h, 2.5h, 3h, etc.
The illumination module 120 can be controlled to match different illumination intensities for different food materials, for example, for blueberries rich in anthocyanin, the anthocyanin gene expression and the synthase activity improvement can be effectively promoted by matching specific blue light intensity, so that the accumulation of functional active ingredients is quickened.
Referring to FIG. 5, in some embodiments, the freshness control method includes, but is not limited to, the following steps:
step S210, obtaining the oxygen concentration and the food variety in the drawer;
step S220, when the oxygen concentration in the drawer is lower than 5%, controlling to start the illumination module to illuminate the food materials, and adjusting the illumination intensity of the illumination module according to the type of the food materials;
and step S230, controlling to turn off the illumination module after 2 hours.
It should be noted that, the embodiment LED lamp may be a blue light or red light LED lamp, and the blue light wave is favorable to promoting accumulation of berry anthocyanin, and the red light can be favorable to improving chlorophyll and carotenoid content of green vegetables. The method specifically can select different colored lights according to the types of food materials, and control and match corresponding illumination intensity and illumination time, so that the content of functional active substances of fruits and vegetables is rapidly improved, and a user can eat fruits and vegetables with higher nutrition in a short time.
Because the transpiration effect of fruits and vegetables can be quickened under the condition of illumination, the preservation period is not beneficial to prolonging, and it can be understood that the transpiration effect is beneficial to being restrained under the environment of high humidity, the preservation device 100 of the embodiment can detect the humidity in the drawer 111 through the humidity sensor, thereby judging whether the humidity in the drawer 111 meets the requirement, when the humidity reaches the level capable of restraining the transpiration effect, the illumination module 120 is controlled to be started for illumination and raising, the transpiration effect generated in the illumination process is reduced, and the influence on the preservation of fruits and vegetables due to the transpiration effect can be reduced.
Specifically, the fresh-keeping control method may determine the humidity condition in the drawer 111, and when the humidity in the drawer 111 reaches the second preset value, control the illumination module 120 to illuminate the food. It should be noted that, the high humidity environment is favorable for suppressing the transpiration, the low oxygen environment is favorable for suppressing the respiration, so that the illumination module 120 is controlled to be turned on after the conditions of low oxygen and high humidity are satisfied in the drawer 111, so that the food materials are illuminated under the conditions of low oxygen and high humidity, and the low oxygen environment can effectively reduce the negative effects of increasing the plant air hole opening degree, accelerating the respiration and transpiration, shortening the fresh-keeping period and the like caused by illumination while improving the content of the nutrients of the fruits and the vegetables, thereby improving the content of the nutrients of the fruits and the vegetables and prolonging the fresh-keeping period of the fruits and the vegetables and meeting the requirements of consumers on the nutrients and the fresh-keeping period of the fruits and the vegetables.
In this embodiment, the second preset value of humidity may be set to 90%, that is, when the humidity in the drawer 111 reaches 90%, it is determined that a high humidity environment is formed in the drawer 111, which may be suitable for suppressing the transpiration.
Referring to FIG. 6, in some embodiments, the freshness control method includes, but is not limited to, the following steps:
step S110, controlling the operation of the deoxidizing module to enable a low-oxygen environment to be formed in the drawer;
step S240, judging the oxygen concentration and humidity in the drawer;
and S250, when the oxygen concentration in the drawer is lower than 5% and the humidity reaches 90%, controlling the blue LED lamp to be turned on for 2 hours.
It should be noted that, when the oxygen concentration in the drawer 111 has not been reduced to 5% or the humidity has not been reached to 90%, the operation of the deaerating module 130 is kept for deaerating, and the LED lamp is temporarily turned off until the low-oxygen and high-humidity environment is satisfied, and then the LED lamp is turned on.
It can be understood that when the drawer 111 is opened to store food, the oxygen concentration and humidity in the drawer 111 will change, and after the drawer 111 is closed again, the oxygen concentration and humidity may not reach the conditions of low oxygen and high humidity, so in the embodiment, after the drawer 111 is opened and closed, the oxygen removal module 130 is controlled to operate, and the oxygen concentration and humidity in the drawer 111 is determined again to determine whether the conditions of low oxygen and high humidity are reached. When the conditions of low oxygen and high humidity are reached in the drawer 111, the LED lamp can be controlled to be turned on again for illumination.
