Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The cooking appliance maturity judging device and method provided by the application can be applied to the application environment of the cooking appliance shown in fig. 1. The cooking appliance can be a steaming oven specifically, and the cooking appliance cooking judging device is arranged in the steaming oven and used for collecting gas in the cooking appliance to obtain collected gas; filtering water vapor in the collected gas to obtain a gas to be detected; detecting the odor value of the gas to be detected and acquiring an odor value threshold corresponding to the cooked state of the preset cooked food; and judging whether the cooked food is cooked or not according to the detected odor value and the odor value threshold. After the cooking utensil cooking judging device detects that the cooked food is cooked, the cooking utensil cooking judging device can send a message to a controller of a steaming oven, and the controller of the steaming oven sends a 'cooked' prompt message to a user, for example, a 'biting and stinging' sound prompt can be sent; or sending out a prompt voice of 'food is cooked', and the like.
As shown in fig. 2, the present application provides a cooking appliance maturity judging apparatus, comprising a gas collecting assembly 100, a gas sensing assembly 200 and a maturity judging assembly 300; the gas collection assembly 100 collects gas in the cooking appliance, the gas sensing assembly 200 filters vapor in the collected gas to obtain gas to be detected, the odor value of the gas to be detected is detected, the detected odor value result is sent to the cooking judging assembly 300, the cooking judging assembly 300 obtains an odor value threshold corresponding to the cooked food cooked state, and whether the cooked food is cooked or not is judged according to the odor value result and the preset odor value threshold.
The gas collection assembly 100 is used to collect gas inside the cooking appliance and collect the collected gas to the gas sensing assembly 200. Specifically, the gas collection assembly 100 can be understood as a gas collection assembly that collects gas within the cooking appliance to the gas sensing assembly 200.
The gas sensing assembly 200 is used for filtering vapor in the collected gas to obtain a gas to be detected, and detecting an odor value in the gas to be detected. On one hand, the water vapor is prevented from influencing the detection result of the odor value because the water vapor is filtered firstly; on the other hand, the influence of water vapor on the service life of the gas value detection hardware can be avoided. Specifically, the gas sensor assembly 200 mainly includes a water vapor filter element and an odor value detector, wherein the water vapor filter element filters water vapor in the collected gas, the gas after filtering the water vapor is sent to the odor value detector, the water vapor filter assembly can adopt a conventional net-shaped filter structure, and because gas molecules are smaller than the water vapor, a filter net with a pore size smaller than the water vapor and larger than air molecules can be arranged to filter the collected gas water vapor, further, in order to prevent the oil molecules (important objects for detecting the odor value) in the gas from being blocked and filtered by the filter net, a novel filter mode can be adopted, for example, a filter net which adsorbs polar molecules can be adopted, because the water vapor belongs to polar molecules, the water vapor can be adsorbed by the filter net, and the oil molecules belong to nonpolar molecules, which can pass through the filter net, so as to be subsequently captured by the odor value detector, And (6) detecting. The odor value detection device may be a gas sensor, and further, in order to achieve higher-accuracy odor value detection, a gas sensor array may be used for detection, and high-accuracy detection may be achieved by using the sensor array.
The cooking judging component 300 is used for comparing the odor value output by the gas sensing component 200 with an odor value threshold corresponding to a preset cooked state of the food, and if the odor value reaches the odor value threshold, judging that the food is cooked; if the smell value does not reach the smell value threshold value, the food is judged to be not cooked temporarily, and the cooking is required to be continued. The preset threshold value of the odor value corresponding to the cooked food in the cooked state is a preset value, and specifically, the preset threshold value of the odor value corresponding to the cooked food in the cooked state can be obtained by collecting the odor value corresponding to the food in the experimental state and writing the odor value into the cooking judging assembly 300 for storage. Optionally, different corresponding smell values in the cooked state can be obtained through experiment collection for different foods, and these data are all written into the cooking judging component 300, and the cooking judging component 300 can actively identify and analyze the type of the food or read the corresponding smell value of the current food in the cooked state based on user operation (for example, the user presses a button for cooking bread).
The cooking utensil maturity judging device collects gas in a cooking utensil to obtain collected gas; filtering water vapor in the collected gas to obtain a gas to be detected; detecting the odor value of the gas to be detected and acquiring an odor value threshold corresponding to the cooked state of the preset cooked food; and judging whether the cooked food is cooked or not according to the detected odor value and the odor value threshold. In the whole process, the collected water vapor in the gas is filtered, so that the influence of the water vapor on the subsequent detection precision of judging the maturity based on the odor value is avoided, and the accurate maturity judgment is realized.
In one embodiment, the judging assembly 300 is further configured to detect a composition of the gas to be detected; identifying a type of food cooked based on the composition; and acquiring an odor value threshold corresponding to the cooked food in a cooked state according to the type of the cooked food.
In the present embodiment, the doneness determining component 300 analyzes the type of the cooked food by active analysis and identification, and further obtains an accurate odor threshold corresponding to the cooked state of the cooked food. In practical application, different foods can release different smells in the cooking process, namely different foods can release gas substances with different components in the cooking process, so that the type of the cooked food can be identified according to the components by detecting the components of the gas to be detected. The odor threshold values corresponding to the cooked states of different foods are stored in the storage space of the judging component in advance, the odor threshold values corresponding to the cooked states of the foods can be stored in a corresponding relation table mode, and the odor threshold values corresponding to the cooked states of the foods can be obtained by directly looking up the table when the types of the cooked foods are identified.
In one embodiment, the gas sensing assembly 200 employs a separation mode for adsorbing polar molecules to filter vapor in the collected gas.
In other application scenarios, the traditional steam filter has filter screens with 18-30 meshes, 40-100 meshes and 480 meshes according to the user requirement, but only a single component can be filtered after determining the type of the filter screen, i.e. the mesh number. When being applied to the cooking utensil scene, because the inside gas of cooking utensil is complicated, the smell of food, the concentration of vapor all have certain difference, the tradition leads to the water net can not filter vapor completely, thereby the net of ventilating can filter the smell of food and cause the gas sensor array to detect the food smell value and can not judge the ripe intelligence of food. Further analysis finds that water is polar molecules and oil is nonpolar molecules, the traditional steam filter is improved, a filter screen of a steam filter part in the gas sensing assembly 200 is made of a special silica gel material which only adsorbs the polar molecules but not adsorbs the nonpolar molecules, the smell of food can be completely adsorbed by water vapor generated in the cooking process of the cooking appliance but not adsorbed by the water vapor, and the smell of the food can be filtered while the water vapor generated in the cooking process and the water vapor generated in the mode selection are filtered by distinguishing the smell and the water vapor generated in the cooking process of the cooking appliance, so that the water vapor can not enter the gas sensor array to be condensed into liquid water to damage the gas sensor array. Furthermore, the steam concentration that different quantity and kind of edible material produced in the culinary art process is also different, and steam filter accessible discernment steam concentration carries out the conversion of filtering strength, avoids still carrying out high-strength steam when steam concentration is less and filters, causes the wasting of resources.
As shown in fig. 3, in one embodiment, the gas sensor assembly 200 includes a silica gel filter 220 and a gas sensor array 240 connected in sequence, the silica gel filter 220 is connected to the gas collection assembly 100, and the gas sensor array 240 is connected to the judgment assembly 300.
Here a silica gel filter 220 is used to adsorb polar molecules. As already mentioned above, water molecules belong to polar molecules and oil molecules belong to nonpolar molecules, and the silica gel filter screen separates the water molecules from the oil molecules by means of adsorption polarity analysis (water molecules), thereby achieving effective water vapor filtration. In addition, the odor value is detected by adopting a gas sensor array mode, and the high-precision odor value detection is further realized.

s200: and collecting gas in the cooking utensil to obtain collected gas.

In the whole process, the collected water vapor in the gas is filtered, so that the influence of the water vapor on the subsequent detection precision of judging the maturity based on the odor value is avoided, and the accurate maturity judgment is realized.
In one embodiment, the method for judging the cooking utensil further comprises the following steps: detecting the composition of the gas to be detected; identifying a type of food cooked based on the composition; and acquiring an odor value threshold corresponding to the cooked state of the preset cooking food according to the type of the cooking food.
In the embodiment, the type of the cooking food is analyzed by adopting an active analysis and identification mode, and then the accurate odor value threshold corresponding to the cooked state of the cooking food is obtained. In practical application, different foods can release different smells in the cooking process, namely different foods can release gas substances with different components in the cooking process, so that the type of the cooked food can be identified according to the components by detecting the components of the gas to be detected. The odor threshold values corresponding to the cooked states of different foods can be stored in the storage space in advance, the odor threshold values can be stored in a corresponding relation table mode, and the odor threshold values corresponding to the cooked states of the foods can be obtained by directly looking up the table when the types of the cooked foods are identified.
In one embodiment, filtering water vapor in the collected gas to obtain the gas to be detected comprises: and filtering water vapor in the collected gas by a separation method of adsorbing polar molecules to obtain the gas to be detected.
The separation method for adsorbing the polar molecules specifically means that water vapor in collected gas is adsorbed by adsorbing the polar molecules, so that effective distinguishing of water molecules and oil molecules is realized, and the water vapor in the gas is effectively filtered out on the premise of not influencing subsequent odor value detection aiming at the oil molecules.
In one embodiment, detecting the odor value of the gas to be detected comprises: and detecting the odor value of the gas to be detected through the gas sensor array.
