Abstract

The present invention can collect data of gas generation, a gas generation period, or a type of gas of food through information detected by a sensor unit of a food container. According to the present invention, a food decomposition determination device is a simple type to be easily handled and transported and does not need additional control except on and off control of a power switch, thereby allowing an old man who is hard to use an electronic/electric device to easily use the device. Therefore, the present invention uses the device when a user is uncertain that the food is decomposed to directly determine whether the food is decomposed and remove a concern of being harm to health by eating the decomposed food. Moreover, according to the present invention, a bacteria detection device affecting decomposition of the food enables a detection sensor to be easily attached thereto, wherein it is important that a storage container has to be sealed.

Description

Refrigerator informs the bacteria generation according to the type and location of food}

Bacterial sensor, food spoilage, Arduino. Refrigerator for corruption

As the technology for storing food is developed, technologies for storing food for a long time without altering the inherent flavor of cooking ingredients have been developed. In the past, food was frozen and stored in a freezer compartment of a refrigerator, but this method has a problem that the flavor is slightly lower than the original when food is cooked by defrosting. Now, rather than frozen, interest in storage technology that does not deteriorate food for as long as possible in a refrigerated state has increased. So, now, the number of households using a kimchi refrigerator together with a refrigerator has increased considerably rather than a conventional refrigerator. However, using a kimchi refrigerator in parallel with a conventional refrigerator has a disadvantage in that it is not economical because space consumption and power consumption are increased. Accordingly, the disclosed technology relates to an apparatus and method for detecting bacteria using a portable terminal in order to solve this disadvantage, and more particularly, to an apparatus and method for detecting and displaying bacteria in a portable terminal by being connected to a portable terminal . With the development of electric/electronic and communication technologies, portable terminals that allow users to freely move while holding and talk freely using wireless have become widespread. These portable terminals have now become a necessity that everyone of all ages has at least one. However, since such a portable terminal is used in contact with or in close contact with the human body, particularly a person's ear and mouth, etc., when sweat or saliva emitted from the user gets on the surface of the portable terminal, various kinds of harmful bacteria are generated. In addition, while carrying the portable terminal, contamination occurs due to the surrounding environment, and harmful bacteria are generated. In order to solve this problem, a sterilization device for a portable terminal, etc., having a function of sterilizing bacteria in a portable terminal has been proposed, but there is a problem in that it is not possible to accurately grasp how much bacteria proliferate in the portable terminal possessed by the user. In addition, in the case of conventional sterilization devices for portable terminals, most of them are proposed as separate devices such as stationary type, so that users can easily identify the degree of bacteria in their mobile terminal whenever necessary, and recognize the necessity of sterilization of the mobile terminal. There is a problem that cannot be done.

Increasing the number of senior citizens is emerging as a new social problem as it goes into a highly industrialized society, and the acceleration of nuclear familyization is accelerating the composition of a generation consisting of only the elderly, either voluntarily or by others. In the case of the elderly, since the sense of smell is relatively aging, it is very difficult to know whether food is spoiled by smell. Therefore, there are often cases where the food is in danger of fatal to health by not knowing that the food is spoiled and being eaten as it is. Accordingly, it is intended to invent a smart bacterial sensor that can visually check the spoilage of food and a refrigerator that works together with it.

The present invention detects a characteristic chemical component that appears when food is spoiled using a sensor connected to an Arduino Uno, and when a characteristic chemical component that appears when food is spoiled is detected, the food is spoiled visually and aurally. By marking, in particular, when elderly people with an aging sense of smell are uncertain whether food is spoiled, a food spoilage determination machine was invented to accurately identify and respond to food spoilage. For this invention, an Arduino acidity measurement sensor, a carbon dioxide sensor, and ammonia and sulfide odor sensors are connected to a food container to analyze various gas generation information over the elapsed period of the food to determine the degree of corruption, and a warning with an LED or speaker. Make a mark.

Normally, food spoilage is caused by bacteria. In the spoiled food, peculiar phenomena, changes in color or the occurrence of a peculiar smell are observed. In the presence of air, the food is decayed by aerobic bacteria, resulting in acetate, sulfate, carbon dioxide, etc. It is known that hydrogen sulfide, ammonia, methane gas, carbon dioxide, etc. are generated by anaerobic bacteria in the absence of air.

Therefore, in order to check whether food is spoiled, it is necessary to detect a characteristic unique chemical component that appears when the food spoils. For example, if the generation of carbon dioxide is detected or other components are detected, it is possible to immediately check whether the food is spoiled. Sensors that detect chemical components during food spoilage as described above are already widely known. Accordingly, the present invention proposes a device that uses this known sensor to determine whether food is spoiled or not.

Packaged foods generate carbon dioxide (CO2) or water (H2O) when decaying, because carbon compounds burn and cause the same mechanism as the chemical reaction below.

Fig. 1 is an embodiment of the present invention

It is possible to collect data such as gas generation and cycle or type of gas for food through the information detected by the sensor part of the food container.

The food spoilage determination device of the present invention is a simple type that is easy to handle and transport, and does not require any other operation other than the ON/OFF operation of the power switch, so it can be easily used even for the elderly who are vulnerable to the use of electronic/electrical devices.

Therefore, it is possible to immediately determine whether or not the food is spoiled by using it when it is questionable whether or not the food is spoiled, and it is possible to eliminate the risk of health hazards caused by eating spoiled food. In addition, the food spoilage of the present invention can be affected. It is important to ensure that the bacteria detection device is easily attached to the detection sensor and that the reservoir is sealed.
