Detailed Description
Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The embodiments described in the examples below do not represent all embodiments consistent with the application. Merely exemplary of systems and methods consistent with aspects of the application as set forth in the claims.
Ethylene is used as ripening gas, which not only accelerates metabolism of fruits and vegetables and shortens the preservation period of food materials. Simultaneously, ethylene can promote the maturation of food materials. However, when the ethylene concentration in the refrigerator is too high, the metabolism of fruits and vegetables is increased, the fresh-keeping period of the fruits and vegetables is shortened, and when the ethylene concentration is too low, the ripening effect of the fruits and vegetables is poor. Especially, the ethylene concentration required by fruits and vegetables with different maturity is different, and the refrigerator can not automatically control the ethylene concentration according to the maturity of the fruits and vegetables, so that the fresh-keeping and ripening effects of the fruits and vegetables are poor.
To solve the problem that the refrigerator can not automatically control the ethylene concentration. Referring to fig. 1 and 2, some embodiments of the present application provide a refrigerator including: the device comprises a refrigerating chamber 1, a ripening area 2, a special area air duct, an air inlet air door 3, an air outlet air door 4, a first gas sensor 6, a second gas sensor 9, an ethylene remover 7, a fan 8 and a controller.
The ripening area 2 is arranged in the refrigerating chamber 1, a special area air channel is connected with the ripening area 2, the first gas sensor 6 and the ethylene remover 7 are arranged in the ripening area 2, the second gas sensor 9 is arranged in the refrigerating chamber 1, the air inlet air door 3 and the air outlet air door 4 are arranged in the special area air channel, and the controller is respectively connected with the air inlet air door 3, the air outlet air door 4, the first gas sensor 6, the second gas sensor 9 and the ethylene remover 7.
The controller is used for: a first gas concentration detected by the first gas sensor 6 is obtained, the first gas concentration including a first ethylene concentration. A second gas concentration detected by the second gas sensor 9 is acquired, the second gas concentration including a second ethylene concentration. Calculating the maturity of the food materials in the ripening zone 2 according to the first gas concentration and the second gas concentration; obtaining an ethylene concentration range corresponding to the food material maturity according to the food material maturity; if the first ethylene concentration and/or the second ethylene concentration exceeds the ethylene concentration range, control instructions are sent to the air inlet air door 3, the air outlet air door 4, the fan 8 and the ethylene remover 7 to control the first ethylene concentration and/or the second ethylene concentration to be within the ethylene concentration range.
Since the ripening area 2 is provided in the refrigerating chamber 1, it is possible to place mature food materials in the refrigerating chamber 1, place immature food materials in the ripening area 2, detect the gas concentration in the ripening area 2 by the first gas sensor 6, and detect the gas concentration in the refrigerating chamber 1 by the second gas sensor 9. Then, the opening or closing of the ethylene remover 7, the blower 8, the air inlet door 3 and the air outlet door 4 is controlled by the gas concentrations detected by the first gas sensor 6 and the second gas sensor 9. For example, when the second ethylene concentration in the second gas concentration detected by the second gas sensor 9 exceeds the maximum ethylene concentration of the cooked food material stored therein, it means that the ethylene concentration in the refrigerating chamber 1 is too high to be advantageous for the cooked food material stored therein, and ethylene can be blown into the ripening zone 2 by controlling the blower 8 and the ethylene remover 7 to be turned on, and the ethylene concentration in the refrigerating chamber 1 can be reduced by the ethylene remover 7 of the ripening zone 2. When the first ethylene concentration in the first gas concentration detected by the first gas sensor 6 exceeds the maximum ethylene concentration for preserving the uncooked food material, the effect of reducing the ethylene concentration can be achieved by controlling the opening of the ethylene remover 7, the air inlet air door 3, the air outlet air door 4 and the fan 8.
In some embodiments, the ripening area 2 is further provided with an air inlet 31 and an air outlet 41, the air inlet 31 and the air outlet 41 are arranged in the special air channel, the air inlet 31 is connected with the air inlet air door 3, and the air outlet 41 is connected with the air outlet air door 4. Through the air inlet 31 and the air outlet 41, the ventilation in the ripening zone 2 can be realized. For example, the air in the special air duct may enter the ripening area 2 from the air inlet 31, and the air in the ripening area 2 may be discharged into the special air duct from the air outlet 41. The air inlet 31 is connected with the air inlet door 3, the air outlet 41 is connected with the air outlet door 4, and the flow of the air in the ripening area 2 can be controlled through the air inlet door 3 and the air outlet door 4 so as to control the concentration of ethylene in the ripening area 2. For example, when the ethylene concentration in the ripening area 2 is too high, the ethylene remover 7 can not effectively reduce the ethylene concentration, the air in the ripening area 2 and the air in the special area air duct can be circulated by opening the air inlet air door 3 and the air outlet air door 4, so that the ethylene concentration in the ripening area 2 is reduced. By providing the air outlet 41 and the air inlet 31, it is convenient to control the ethylene concentration in the ripening zone 2.
In some embodiments, the first gas sensor 6 and the second gas sensor 9 are each one or more of a semiconductor gas sensor, an electrochemical gas sensor, a catalytic combustion gas sensor, a thermal conductivity gas sensor, an infrared gas sensor, and a solid electrolyte gas sensor. A gas sensor is a transducer that converts a certain gas volume fraction into an electrical signal. For example, semiconductor sensors are fabricated using oxidation-reduction reactions of gases at the semiconductor surface to cause the resistance of the sensing element to occur, and specific materials may be used to increase the sensitivity of the sensor to certain types of gases. Electrochemical sensors can derive gas concentration by measuring the current generated by the gas as it is oxidized or reduced at the electrode. Through setting up first gas sensor 6 and second gas sensor 9, can be accurate detect the gas concentration of cold-stored room 1, ripening zone 2, judge the ripeness condition of food through gas concentration to obtain ethylene concentration through the gas concentration that detects, and then judge whether ethylene concentration is exceeding ethylene concentration range according to the ripeness condition of food. The ethylene concentration is conveniently controlled in a correct range, and the fresh-keeping effect or ripening effect is improved.
In some embodiments, the ethylene remover 7 is a device that removes ethylene based on one or more principles of physical adsorption material, physical catalysis, photocatalysis, ozone reaction, chlorine dioxide reaction. Wherein the ethylene remover 7 can physically and chemically remove ethylene from the gas. For example, the physical catalysis can use activated carbon, alumina and other materials to adsorb ethylene, and can also use photocatalysis, ozone and chlorine dioxide to oxidize and decompose ethylene, and an ethylene remover 7 is arranged in the ripening zone 2, so that the ethylene concentration of the ripening zone 2 and the refrigerating chamber 1 can be conveniently controlled.
In some embodiments, the refrigerator further comprises a ventilation membrane 5, wherein the ventilation membrane 5 is arranged on the upper wall of the ripening zone 2, and the ventilation membrane 5 is used for communicating the refrigerating chamber 1 and the ripening zone 2. Wherein the gas permeable membrane 5 is an ethylene separation membrane module. Through setting up ventilated membrane 5 at the upper wall of ripening zone 2, can pass through ethylene separation membrane module with the ethylene that the food metabolism of cold-storage chamber 1 produced and shift to ripening zone 2 on the one hand, reduce cold-storage chamber 1 ethylene concentration, improve the fresh-keeping effect of food in the cold-storage chamber 1, on the other hand can also improve ripening zone 2 ethylene concentration, be convenient for promote ripened food.

For example, when the first gas sensor 6 detects the first gas concentration in the ripening zone 2, the first gas concentration includes a carbon dioxide concentration, an ethanol concentration, and a first ethylene concentration, the controller calculates the food ripeness according to the carbon dioxide concentration and the ethanol concentration after obtaining the first gas concentration, and when the result of calculation is that the food ripeness is already reached, it is calculated whether the first ethylene concentration is within a first preset range. When the first ethylene concentration exceeds the maximum value of the first preset range, the first ethylene concentration needs to be reduced, and the controller can control the fan 8 and the ethylene remover 7 to be started, so that the first ethylene concentration in the ripening zone 2 is reduced, and the first ethylene concentration is controlled within the first preset range. The ethylene concentration in the ripening zone 2 is automatically controlled by turning on the controller fan 8 and the ethylene remover 7.
In some embodiments, if the food material maturity is immature, obtaining a second preset range; if the first ethylene concentration is greater than the maximum value of the second preset range, the controller sends an opening instruction to the fan 8 and the ethylene remover 7 so as to control the fan 8 and the ethylene remover 7 to be opened; if the first ethylene concentration is smaller than the minimum value of the second preset range, sending a discontinuous opening instruction to the fan 8 and the ethylene remover 7 so as to control the fan 8 and the ethylene remover 7 to be opened discontinuously. When the ethylene concentration in the ripening zone 2 is greater than the maximum value of the second preset range, it is necessary to reduce the ethylene concentration in the ripening zone 2, and the blower 8 and the ethylene remover 7 may be controlled to be turned on, and the ethylene is adsorbed or decomposed by the ethylene remover 7, so that the ethylene concentration is reduced. When the ethylene concentration in the ripening area 2 is smaller than the minimum value of the second preset range, the ethylene concentration in the ripening area 2 needs to be increased, the ethylene in the refrigerating chamber 1 enters the ripening area 2 through the breathable film 5 by simply starting the fan 8, and then the ethylene remover 7 is intermittently started, so that the ethylene concentration in the ripening area 2 is kept in the second preset range. The ripening effect of the ripening area 2 is improved by controlling the fan 8 and the ethylene remover 7 to be opened intermittently.
It can be understood that when the second ethylene concentration in the second gas concentration in the refrigerating chamber 1 is higher than the preset range, the blower 8 is turned on to enable the ethylene in the refrigerating chamber 1 to enter the ripening chamber through the air permeable membrane 5, and then the ethylene remover 7 is turned on to adsorb and decompose the ethylene, so as to achieve the effect of reducing the ethylene concentration in the refrigerating chamber 1 and improve the fresh keeping capability of the refrigerating chamber 1.
