Abstract
The utility model discloses a refrigerator capable of prompting food fresh preservation degree, which is capable of detecting freshness of foods in the refrigerator and reminding a user of the freshness. A gas sensor is mounted in a storage chamber of the refrigerator, and connected with a gas detection data input end of a refrigerator controller through an A/D (analog-to-digital) converter, a preset freshness data storage device is connected with a data input end of the refrigerator controller, a freshness level voice signal input end of the refrigerator controller is connected with a signal input end of a voice prompter. The gas sensor is added to the refrigerator to detect air content in the refrigerator so as to detect freshness of foods in the refrigerator and to prompt users on freshness, so that users can well master the conditions of the foods in the refrigerator so as to handle situations in time and prevent food spoilage.
Description
Technical field
The utility model relates to a kind of refrigerator, in particular, relates to a kind of refrigerator that the food fresh keeping degree is reminded that has.
Background technology
Nowadays refrigerator has become the electrical equipment of indispensability in people's life, the vegetables that people's custom will buy, melon and fruit, meat etc., even the food of not eating up is stored in the refrigerator.Just allow the people forget easily and the thing of storage is many more, and addle after making the long-time placement of food, not only influence the smell of refrigerator, and the food that addles can quicken addling of interior other food of refrigerator.Cause the waste of food.
The utility model content
The utility model is in order to overcome weak point of the prior art, and providing a kind of can detect the freshness of food in the refrigerator, and the user is carried out the refrigerator that freshness is reminded.
The utility model is achieved through the following technical solutions:
A kind of refrigerator that has the prompting of food fresh keeping degree, it is characterized in that, in refrigerator storeroom inside gas sensor is installed, described gas sensor detects data input pin by A/D converter with the gas of refrigerator controller and is connected, preset the freshness data storage and be connected with the data input pin of described refrigerator controller, described refrigerator controller freshness class voice signal output part is connected with the signal input part of voice prompting device.
Described gas sensor is at least a in CO gas sensor, ethylene gas sensor, the these hydrogen sulfide gas sensor.
The utlity model has following technique effect:
The utility model detects the air content in the refrigerator by add gas sensor in refrigerator, thereby realize detection to food freshness in the refrigerator, and the user is carried out the prompting of freshness, make the user can be good at grasping the situation of food in the refrigerator, in time handle, prevent spoilage.
Description of drawings
Fig. 1 has the internal circuit schematic diagram of the refrigerator of food fresh keeping degree prompting for the utility model is a kind of.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Fig. 1 has the internal circuit schematic diagram of the refrigerator of food fresh keeping degree prompting for the utility model is a kind of, in refrigerator storeroom inside gas sensor is installed, described gas sensor detects data input pin by A/D converter with the gas of refrigerator controller and is connected, preset the freshness data storage and be connected with the data input pin of described refrigerator controller, described refrigerator controller freshness class voice signal output part is connected with the signal input part of voice prompting device.
Wherein, described gas sensor is at least a in CO gas sensor, ethylene gas sensor, the these hydrogen sulfide gas sensor, can select as required.
At first, when obtaining food difference freshness by experiment, the concentration and the relative scale of gases such as surrounding air carbon monoxide, ethene, hydrogen sulfide, these data are copied in the refrigerator chip database, and set the spoilage early warning value, will be scheduled to the food freshness data and deposit in and preset in the freshness data storage.
Gas sensor detects the concentration and the relative scale of gases such as carbon monoxide, ethene, hydrogen sulfide in the interior air of refrigerator in real time, deliver in the refrigerator controller, the data that refrigerator controller detects gas sensor with preset the normal data of storing in the freshness data storage and compare, thereby judge the freshness of food in the refrigerator.If reach the spoilage early warning value, because of vegetables, it is different with ratio to discharge gaseous species when fruit and meat etc. addle, then compare and carry out preliminary judgement by further data, when the user opens refrigerator next time, to voice prompting device, the food by which kind of type of voice suggestion user has the sign that obviously addles to refrigerator controller, and the user can promptly and accurately be handled food with freshness class voice signal output part.
Claims (2)
1. one kind has the refrigerator that the food fresh keeping degree is reminded, it is characterized in that, in refrigerator storeroom inside gas sensor is installed, described gas sensor detects data input pin by A/D converter with the gas of refrigerator controller and is connected, preset the freshness data storage and be connected with the data input pin of described refrigerator controller, described refrigerator controller freshness class voice signal output part is connected with the signal input part of voice prompting device.
2. a kind of refrigerator that the food fresh keeping degree is reminded that has according to claim 1 is characterized in that, described gas sensor is at least a in CO gas sensor, ethylene gas sensor, the these hydrogen sulfide gas sensor.
