But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.
The refrigerator has the functions of preserving, refrigerating and freezing food materials. First, the structure, function, and the like of the refrigerator will be described in detail. The refrigerator provided by the embodiment of the application comprises a compressor, a refrigerating fan, a condensing fan, a door body (a door), a refrigerator body and a display screen; the door body is arranged on the outer side of the box body; the compressor, the refrigeration fan and the condensation fan are arranged in the box body, the controller is arranged on the box body and in the box body, and the controller is electrically connected with the compressor, the refrigeration fan and the condensation fan.
In order to bring better user experience, the refrigerator can determine the food material information in the storage room according to the associated tags, and monitor the freshness of the food material according to the food material information, so that a user can eat the food material better; however, the purchased food materials can carry harmful substances, or the food materials can generate harmful substances along with the accumulation of the harmful substances, so that the health of the user can be damaged when the user eats the food materials. There is a need for a target substance degradation function to remove harmful substances in food materials and provide healthier food materials for users.
In some embodiments, the target substance to be degraded may be purine, nitrite, pesticide residue, oxalic acid, and the like. In the specific implementation manner of the present application, oxalic acid is taken as an example to explain the technical scheme of the present application.
Oxalic acid is a metabolite in organisms, widely distributed in plants, animals and fungi, and performs different functions in different organisms. Oxalic acid is a harmful substance in food, and long-term intake of food with high oxalic acid content can affect the absorption of minerals by human body, resulting in anemia, renal calculus and other symptoms. Oxalic acid is not easy to be oxidized and decomposed in human body, and the product formed after metabolism belongs to acidic substance, which can cause the pH value in human body to lose balance, and can cause poisoning after being too much eaten. In addition, if oxalic acid meets calcium and zinc in human body, calcium oxalate and zinc oxalate are generated, and are difficult to absorb and discharged out of body, thus influencing the absorption of calcium and zinc. The children need a large amount of calcium and zinc for growth and development, and if the calcium and the zinc are deficient in the body, the deficiency not only can cause poor development of bones and teeth, but also can affect the intelligence development.
In order to solve the above problems, the present application provides a method for degrading a target substance, so as to remove harmful substances in food materials and provide healthier food materials for users.
As shown in fig. 1, the program steps of the method for degrading target substances of the refrigerator, which are executed by the refrigerator in the following embodiments, are all performed by the controller in cooperation with other components in the refrigerator.
In order to realize the target substance degradation method, the refrigerator is also provided with a degradation device which is fixedly connected to the inner wall of the storage chamber through a buckle, and the top of the degradation device is provided with a top cover, so that a user can add the degradation substance to the degradation device through the top cover; and a plurality of small holes are formed in the two sides of the degradation device, so that the degradation device can release the degradation gas. Electric valves are arranged on two sides of the degradation device and electrically connected with the controller, and the electric valves are configured to control the degradation device to release and stop releasing degradation gas. The top of the storage room is fixedly provided with a sensor which is electrically connected with the controller, and the sensor is configured to detect the concentration of the target substance in the storage room in real time.
S101: and responding to a degradation instruction of a user, controlling the degradation device to perform degradation operation, releasing degradation gas, and performing timing operation.
The refrigerator can obtain a degradation instruction sent by a user. The degradation instruction can be directly sent to the refrigerator by a user or sent to the refrigerator by the user through other equipment.
In some embodiments, the user may send the degradation instruction to the refrigerator through a control device, where the control device may be a remote controller, a mobile phone, a tablet computer, or the like.
In some embodiments, the user may also send degradation instructions directly to the refrigerator. For example, directly sending voice commands, touch commands, etc. to the refrigerator.
After receiving the degradation instruction, a controller in the refrigerator controls electric valves on two sides of the degradation device to be started so that the degradation device releases degradation gas from the small hole; the controller in the refrigerator controls the sensor to detect the concentration of the target substance in the storage chamber while the electrically operated valves at both sides of the degradation device are activated. In some embodiments, the target substance is oxalic acid, and the concentration of oxalic acid may be calculated from the concentration of the degradation gas.
In some embodiments of the present application, the degradation device is a chlorine dioxide release device and the degradation substance is chlorine dioxide, the chlorine dioxide comprising a variety of forms including, but not limited to, chlorine dioxide solid particles, chlorine dioxide microcapsules, or chlorine dioxide gel. Wherein the diameter of the plurality of small holes of the chlorine dioxide release device is smaller than the diameter of the chlorine dioxide particles, the chlorine dioxide microcapsules or the chlorine dioxide gel.
The oxalic acid component in the food material can be degraded through the treatment of chlorine dioxide with certain concentration. The degradation principle is as follows: oxalic acid is a reducing substance, is easily oxidized and decomposed, and chlorine dioxide has strong oxidizing property, so that oxalic acid in food materials can be oxidized by chlorine dioxide. The chlorine dioxide does not affect the original flavor and appearance quality of fruits and vegetables in the treatment process, and is suitable for degrading oxalic acid in food materials in a refrigerator; and the chlorine dioxide also has the functions of sterilization and peculiar smell removal, and can further purify the storage environment in the refrigerator.
S102: and detecting whether a termination condition is met, wherein the termination condition comprises that the timing time reaches a preset time and/or the concentration of the target substance is equal to a preset concentration value.
When the electric valves on the two sides of the degradation device are started, a controller in the refrigerator starts timing operation, the timing duration is compared with the preset duration, and when the timing duration reaches the preset duration, the termination condition is determined to be met.
After the degradation device releases the degradation gas, the controller determines the concentration of the target substance according to the concentration of the degradation gas sensed by the sensor, and when the concentration of the target substance is equal to the preset concentration, the controller determines that the termination condition is met.
S103: and controlling the degradation device to stop releasing degradation gas and change the refrigeration state of the storage chamber to a preset state when the end condition is detected to be met.
When the termination condition is met, the controller controls the electric valves on the two sides of the degradation device to be closed, the degradation device stops releasing the degradation gas, the storage chamber returns to the preset state to operate, and the preset state can be a common refrigeration state.
As shown in fig. 2, the following example is an example explanation based on the above steps:
after food materials are put into the storage chamber 1, a user opens the oxalic acid reducing function button arranged on the display screen 5, the chlorine dioxide release device 3 and the chlorine dioxide concentration sensor 4 in the storage chamber 1 are simultaneously started, and the chlorine dioxide release device 3 releases degradation gas, namely chlorine dioxide gas; when the chlorine dioxide concentration sensor 4 detects that the concentration of chlorine dioxide in the storage chamber 1 is 0.5ppm, the controller 2 controls the electric valves 33 and 34 on the two sides of the chlorine dioxide release device 3 to be closed, the chlorine dioxide release device 3 stops releasing chlorine dioxide gas, the storage chamber 1 returns to a common refrigeration state to operate, after 24 hours, the controller 2 automatically controls the electric valves 33 and 34 on the two sides of the chlorine dioxide release device 3 to be opened, the chlorine dioxide release device 3 continues to release chlorine dioxide gas, the chlorine dioxide gas contacts with food materials in the storage chamber 1, and oxalic acid in the food materials is degraded.
Referring to fig. 3, in some embodiments of the present application, the method further comprises:
s201: acquiring the freshness of food materials in the storage chamber every preset time and recording the times of degradation operation;
s202: and when the freshness of the food materials is lower than a preset freshness threshold value, or the degradation operation times exceed preset times, controlling a display screen to display an interface prompt and play a voice prompt in a user interface so as to prompt a user to process the food materials.
By acquiring the freshness of the food materials in the storage chamber and recording the number of degradation operations, on one hand, the concentration of degradation gas in the storage chamber can be controlled, and meanwhile, the service life of the chlorine dioxide release device can be prolonged, so that waste is avoided, and electricity is saved; on the other hand, the situation that the food materials are placed in the storage chamber for a long time and are treated by oxalic acid for many times, so that the nutritional value is reduced and the food is influenced is avoided.
Referring to fig. 4, in some embodiments of the present application, the method further comprises:
s301: acquiring the door state of the storage chamber door;
s302: when the door state of the storage chamber is a closed state, controlling the degradation device to perform degradation operation according to a first rule; the first rule is a degradation cycle for controlling the degradation device to operate for a preset number of times within a preset time length;
s303: when the state of the door of the storage chamber is changed, controlling the degradation device to perform degradation operation according to a second rule; the second rule is that the degradation device is controlled to stop executing degradation operation when the condition that the termination condition is met is detected.
The start-stop control of the degradation device is divided into a first rule (automatic control) and a second rule (door opening and closing control). Under the condition that the storage chamber is not opened, the degradation device runs for a preset number of degradation cycles within a preset time length, and in some embodiments, the degradation device automatically closes after continuously working for at most 3 cycle cycles, so that the situation that a user forgets to close the oxalic acid reduction function key can be prevented, and the service life of chlorine dioxide can be prolonged.
When the chamber door state of storeroom was closed state all the time in first time length, degradation device was according to first rule operation, if when detecting the chamber door state change of storeroom once more, the electric valve of controller control degradation device both sides opened, according to established rule operation. The established rule is that the degradation device is controlled to stop executing degradation operation when the termination condition is met. It should be noted that the change in the door state of the storage chamber means that the door state of the storage chamber is changed from "closed" - "open" - "closed".
