Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The main solution of the embodiment of the invention is as follows: based on the cooking appliance comprising the storage box and the detection device arranged corresponding to the storage box, the detection signal of the detection device is obtained, the storage state information of the cooking appliance is determined according to the detection signal, and if the storage state information meets the set cooking condition, the cooking appliance is controlled to execute cooking operation.

In the prior art, the automatic cooking function of the electric appliance can immediately execute cooking operation after receiving a starting instruction of the function, so that the problem of poor cooking effect exists.

The invention provides the solution, and aims to effectively detect the material state in the cooking appliance so as to meet the cooking requirement of a user.

The embodiment of the invention provides an operation control method which is applied to detecting the material state in a cooking appliance. The cooking appliance can be any electric appliance with a storage box for loading cooking materials, such as an electric cooker, a coffee machine, a food processor, a wall breaking machine and the like.

Cooking utensil includes storage case and corresponds the detection device that the storage case set up. The detection device is specifically used for detecting the loading condition of the storage box and/or the placement condition of the storage box in the electric appliance. The type of the detection device can be set according to actual conditions, and for example, the detection device can be one or more of a light detection device, an elastic detection device, an image detection device, a weight detection device, a temperature detection device and the like, which can accurately measure the material condition. The position of the detection device can be set according to actual conditions, for example, the detection device can be arranged outside the storage box, inside the storage box, above the storage box or below the storage box.

Based on the above cooking appliance, an embodiment of the operation control method of the present application is provided. In the present embodiment, referring to fig. 1, the operation control method includes the steps of:

step S10, acquiring a detection signal of the detection device;

the detection signal is specifically a characterization signal obtained by detecting the storage condition of the cooking appliance by the detection device. The type of the detection signal varies with the detection device, and may include, for example, a light detection signal, an image signal, a deformation signal of the material storage box, a temperature signal, and the like.

The transmitted signal, the received signal, the variation of the signal, the variation rate of the signal and the like of the detection device are monitored to obtain the detection signal. The acquisition mode of the detection signal can be adapted to different principles of the detection device for detecting the material, for example, when the detection device comprises a signal transmitter and a signal receiver, the signals of the two modules need to be monitored simultaneously to obtain the detection signal; for another example, when the detection device is an image acquisition module, the detection device can directly acquire an image signal acquired by the image acquisition module to obtain a detection signal therein.

Specifically, step S10 may be performed after receiving a start instruction of the cooking function input by the user.

Specifically, in this embodiment, the storage box includes a light-transmitting portion, the detection device includes a light detection device disposed corresponding to the light-transmitting portion, based on which the detection signal includes a light detection signal, and then step S10 includes: and determining the storage state information according to the optical detection signal. In particular, the light detection means may be a light sensor or may be a detection assembly having a light emitter and a light receiver. Different material storage states of the cooking utensil form different light detection signals in the light detection device. For example, the optical detection signal is different when a material is placed than when no material is placed; the optical detection signals are different when the material storage box is placed in the electric appliance and not placed in the electric appliance.

S20, determining the storage state information of the cooking appliance according to the detection signal;

the storage state information specifically refers to characteristic information representing the current material placement condition of the cooking appliance. The storage state information may include information on the material storage amount of the storage tank, information on the placement state of the storage tank, and/or information on the temperature of the material in the storage tank.

Different detection signals correspond to different storage state information. The corresponding relation between the detection signal and the storage state information can be established in advance based on the detection principle, the installation position and the like of the detection device, and the storage state information corresponding to the current detection signal can be determined based on the corresponding relation. Specifically, different set material storage state information in the corresponding relationship may correspond to different set characteristic signals, and if the detection signal matches the set characteristic signal, the set material storage state information corresponding to the set characteristic information may be determined to be the current material storage state information of the cooking appliance.

For example, can produce different signals in detection device when the material is placed and not placed to the storage case, then can acquire signal that detection device corresponds respectively when multiple different materials are placed to the storage case and when not placing as first sample, first characteristic signal and the second characteristic signal that corresponds respectively when obtaining the storage case and placing the material when not placing the material based on first sample analysis, the first state and the first characteristic signal relevance of material are placed to the storage case, the second state and the second characteristic signal relevance of material formation first corresponding relation are not placed to the storage case. Based on this, when the detection signal matches the first characteristic signal, the stock state information is determined to be in the first state, and when the detection signal matches the second characteristic signal, the stock state information is determined to be in the second state.

If the storage box is provided with different detection signals formed by different amounts of materials in the detection device, the signals corresponding to the storage box when different amounts of materials are placed can be obtained as second samples, and the third characteristic signals corresponding to the storage box when different amounts of materials are placed are obtained based on analysis of the second samples. And associating different third characteristic signals with the material storage amount of the corresponding material storage box to form a second corresponding relation. Based on the above, when the third characteristic signal matched with the detection signal exists, the material storage amount of the material storage box associated with the matched third characteristic signal can be determined as the material storage state information.

Or different detection signals can be formed in the detection device when the storage box is placed at the designated position and is not placed at the designated position, then signals respectively corresponding to the storage box when the storage box is placed at the designated position and is not placed at the designated position for multiple times can be obtained and serve as third samples, fourth characteristic signals and fifth characteristic signals respectively corresponding to the storage box when the storage box is placed at the designated position and is not placed at the designated position are obtained based on analysis of the third samples, the storage box is placed at the designated position and is associated with the first characteristic signals, and the storage box is not placed at the designated position and is associated with the second characteristic signals to form a third corresponding relation. Based on the above, when the detection signal is matched with the fourth characteristic signal, the storage state information can be determined that the storage box is placed at the designated position, and when the detection signal is matched with the fifth characteristic signal, the storage state information can be determined that the storage box is not placed at the designated position.

Step S30, judging whether the storage state information meets set cooking conditions or not;

if the storage state information meets the set cooking condition, executing a step S40; and if the material storage state information does not meet the set cooking condition, executing step S50.

The cooking condition setting specifically refers to a standard that the cooking appliance aims to cook food meeting the requirements of the user and the required storage condition reaches. The cooking conditions may specifically include the amount of material stored required for cooking, the requirement of the storage box for placement position, the temperature of the material required for cooking, and the like.

The set cooking conditions may be pre-existing default conditions of the system or may be determined based on parameters input by the user.

The set cooking conditions may be different depending on the type of cooking. For example, porridge and rice may correspond to different set cooking conditions. Specifically, the user can determine the cooking type required by the user by analyzing the instruction input by the user, and then read the corresponding pre-stored cooking condition as the set cooking condition.

And step S40, controlling the cooking appliance to perform cooking operation.

And S50, controlling the cooking appliance to stop executing the cooking operation and outputting prompt information.

The storage state information meets the set cooking conditions, and the current storage state of the cooking appliance can be considered to ensure that the cooking appliance cooks food meeting the requirements of users by using the materials currently stored in the storage box, so that cooking operation (for example, materials are transported to a cooking cavity or the storage box is directly heated, and the like) can be performed; the storage state information does not meet the set cooking condition, and the current storage state of the cooking appliance can be considered to be difficult to ensure that the cooking appliance cooks food meeting the requirements of a user by using the materials currently stored in the storage box, so that the cooking operation is forbidden to be executed, and prompt information is output to prompt the user, so that the user can adjust the storage state of the cooking appliance in time. Specifically, different stock state information can correspond to different prompt messages, so that a user can accurately know the content required to be adjusted at the current period.

The prompt information may specifically include output in the form of display, sound, light, and the like. For example, the display screen of the cooking appliance may be controlled to display the prompt information or push the prompt information to the terminal of the user to prompt the user.

The operation control method provided by the embodiment of the invention is based on the fact that the operation control method comprises a material storage box and a detection device arranged corresponding to the material storage box, the method detects the material storage state information of the cooking appliance based on a detection signal of the detection device before cooking, cooking is carried out only when the material storage state information meets set cooking conditions, effective detection on the material state in the cooking appliance and whether the material state meets the cooking requirements or not is realized through acquisition of the material storage state information and matching of the material storage state information and the set cooking conditions, and the material storage state can be matched with the cooking requirements during cooking of the cooking appliance, so that the cooking requirements of users are met. Wherein, do not carry out the culinary art when storage state and culinary art demand mismatch to avoid the safety problem that no-load culinary art leads to, also can avoid the not good problem of culinary art effect that the material is not enough to lead to, further ensure that the culinary art operation can accurately match with user's culinary art demand.

Further, based on the above embodiment, another embodiment of the operation control method of the present application is provided. In this embodiment, the storage box includes a light-transmitting portion, the detection device includes a light detection device disposed corresponding to the light-transmitting portion, the detection signal includes a light detection signal, the light detection device includes a first light detection module, and the light-transmitting portion includes a first sub light-transmitting portion disposed corresponding to the first light detection module. Based on this, the storage status information includes the placement status information of the storage bin, and referring to fig. 2, the step of determining the storage status information according to the optical detection signal includes:

step S21, determining a first magnitude relation between a first optical detection signal and a first set signal threshold; the first optical detection signal is a signal detected by the first optical detection module;

specifically, the first optical detection signal can be obtained from a signal detected by the first optical detection module, which is acquired in real time after the cooking appliance is started or after a setting instruction of a user is received.

The first setting signal threshold is specifically a preset critical value for distinguishing the light detection signal detected by the first light detection module corresponding to different states of the material storage box relative to the cooking device (e.g., a state that the material storage box is already placed in the cooking device or a state that the material storage box is not placed in the cooking device). The first setting signal threshold may be different according to an optical characteristic of the first sub light-transmitting portion and/or a signal detection characteristic of the first light detection module.

The first magnitude relation specifically includes that the first optical detection signal is greater than a first set signal threshold, the first optical detection signal is less than the first set signal threshold, and the first optical detection signal is equal to the first set signal threshold.

And S22, determining the placement state information of the storage box according to the first size relationship.

The placement state information of the bin specifically refers to position state information representing the current bin relative to the cooking appliance. Specifically, the placement state information of the material storage box comprises information that the material storage box is placed on the cooking appliance and information that the material storage box is not placed on the cooking appliance.

The different first size relations correspond to different storage box placement state information. The corresponding relationship between the first size relationship and the placement state information of the material storage box can be established in advance based on the light characteristics of the first sub light transmission part and the signal detection characteristics of the first light detection module. The storage box placing state information corresponding to the current first size relation can be determined based on the corresponding relation to represent the placing state of the storage box on the current cooking appliance.

In this embodiment, the first sub light-transmitting portion is provided with a total reflection prism. When the first sub light-transmitting part is aligned with the first light detection module, light emitted by the first light detection module can be reflected back to the first light detection module under the action of the total reflection prism; when the first sub light transmission part and the first optical detection module are staggered or far away from each other, the light emitted by the first optical detection module cannot return to the first optical detection module due to the absence of total reflection. Specifically, in this embodiment, when the first optical detection module cannot receive the light emitted by the first optical detection module, the corresponding detection signal is infinite; when the first light detection module receives the light emitted by the first light detection module, the corresponding detection signal is close to 0. Based on this, if the first magnitude relation is that the first optical detection signal is greater than the first set signal threshold, it is determined that the storage bin is not placed on the cooking utensil; if the first magnitude relation is that the first optical detection signal is smaller than or equal to the first set signal threshold, the storage box placement state information is determined that the storage box is not placed in the cooking utensil.

For example, the cooking device is provided with two storage boxes, one storage box is a rice box and is used for placing rice, the other storage box is a water tank and is used for discharging water, the placing state information can comprise placing state information of the rice box and placing state information of the water tank, based on the placing state information, a first light detection signal corresponding to the rice box is defined as X1, a first light detection signal corresponding to the water tank is defined as X2, a first set signal threshold value is A, the rice box can be considered not to be placed in the cooking device when X1 & gtA, the water tank can be considered not to be placed in the cooking device when X1 & ltA & gt, the rice box can be considered to be placed in the cooking device when X2 & ltA & gt is not larger than A, and the rice box can be considered to be placed in the cooking device when X2 & ltA.

Further, in this embodiment, the total reflection prism has a first surface, a second surface and a third surface, the first surface is disposed on the outer surface of the storage box, and the second surface and the third surface are perpendicularly intersected and located in the storage box. Specifically, the third surface is the outer surface of the storage box, the first surface and the second surface are the inner surfaces of the storage box, and when the storage box is placed in the cooking device, the first light detection device is arranged outside the storage box and corresponds to the third surface. The light emitted by the first optical detection device is vertically incident to the first surface, and is reflected on the second surface and the third surface in sequence, and finally the reflected light is incident to the first optical detection device.

In this embodiment, the storage box is accurately characterized in placement state based on the first magnitude relation between the first optical detection signal and the first set signal threshold, so that whether the storage box of the cooking device is placed on the cooking device is accurately identified, cooking can be performed subsequently when the storage box is confirmed to be placed in the cooking device, and safety risk or device damage caused by no-load cooking of the cooking device is avoided.

Further, based on the above embodiment, another embodiment of the operation control method of the present application is provided. In this embodiment, the optical detection apparatus further includes a second optical detection module, where the second optical detection module and the first optical detection module are disposed at an interval, and specifically, the second optical detection module may be located above the first optical detection module. The light transmission part also comprises a second sub light transmission part which is arranged corresponding to the second light detection module, and the second sub light transmission part is positioned above the first sub light transmission part. The light transmission structure of the second sub light transmission part and the light transmission structure of the first sub light transmission part can be set to be the same or different structures according to actual requirements. When the light transmission structure of the second sub light transmission part is different from the light transmission structure of the first sub light transmission part, in order to avoid mutual interference of detection results, a partition plate can be arranged in the storage box to separate the spaces corresponding to the two sub light transmission parts.

In this embodiment, the material storage status information further includes material placement status information of the material storage tank, and based on this, referring to fig. 3, after step S22, the method further includes:

specifically, the second optical detection signal can be obtained from a signal detected by the second optical detection module, which can be obtained in real time after the cooking appliance is started or after a setting instruction of a user is received, and the first optical detection signal and the second optical detection signal can be obtained simultaneously or sequentially according to actual requirements.

The second setting signal threshold is specifically a preset critical value for distinguishing the light detection signals detected by the second light detection modules corresponding to different states of the material placed in the material storage tank (for example, the material exists in the material storage tank, the material does not exist in the material storage tank, different amounts of the material are stored, and the like). The second setting signal threshold may be different according to an optical characteristic of the second sub light-transmitting portion and/or a signal detection characteristic of the second light detection module.

Specifically, the deviation amount between the second setting signal threshold and the first setting signal threshold is greater than or equal to a preset value. For example, if the first threshold value is defined as A and the second threshold value is defined as B, | A-B | > the predetermined value. In the present embodiment, the preset value is 50, and in the present embodiment, is 50, and other embodiments may also be set as 45, 80, 60, and the like according to the actual situation. In the embodiment of the present invention, the first optical detection signal, the second optical detection signal, the first setting signal threshold, and the second setting signal threshold are all values of digital quantities into which analog quantity voltages of the optical detection device are converted. The preset value is set, so that different storage state information in the cooking appliance can be accurately identified, and whether the subsequent accurate judgment on the storage state information meets the cooking requirement or not is guaranteed.

The second magnitude relationship specifically includes that the second optical detection signal is greater than a second setting signal threshold, the second optical detection signal is less than the second setting signal threshold, and the second optical detection signal is equal to the second setting signal threshold.

And S24, determining the material placement state information according to the second size relationship.

The material placement state information specifically refers to characteristic information representing the material placement condition of the current material storage tank. Specifically, in this embodiment, the material placement state information may include first state information and/or second state information, and the like. The first state information is information that materials in the material storage box exist or do not exist, and the second state information is information of material storage quantity in the material storage box.

The different second size relationships correspond to different material placement state information. The correspondence between the second size relationship and the material placement state information may be established in advance based on the optical characteristics of the second sub light-transmitting portion and the signal detection characteristics of the second optical detection module. And determining the material placing state information corresponding to the current second size relationship based on the corresponding relationship to represent the material placing state in the current storage box.

In this embodiment, the material placement state in the material storage tank is accurately characterized based on the second magnitude relationship between the second optical detection signal and the second setting signal threshold, so that the material placement state in the cooking device is accurately identified, cooking can be performed only when the material placement state is confirmed to meet the cooking requirement, and the problem of poor cooking effect caused by too much or too little material is avoided.

Further, in this embodiment, the material placement state information includes first state information, where the first state information is information about existence or nonexistence of the material in the storage bin, and the step S24 includes:

step S241, if the second size relationship matches the set size relationship corresponding to the storage bin, determining that the first state information is that materials exist in the storage bin; a (c)

In step S242, if the second size relationship does not match the set size relationship, it is determined that the first status information indicates that no material exists in the storage bin.

In this embodiment, the preset magnitude relationship specifically refers to a magnitude relationship between the second optical detection signal and the second setting signal threshold when the material exists in the material storage box, and may be determined in advance according to the signal detection characteristic of the second optical detection module, the material characteristics stored in the material storage box, the optical characteristics of the light-transmitting portion, and the like.

It should be noted that, in other embodiments, the set size relationship may also refer to a size relationship between the second optical detection signal and a second set signal threshold when the preset material does not exist in the material storage box, at this time, if the second size relationship matches the set size relationship, it is determined that the first status information is that the material does not exist in the material storage box, and if the second size relationship does not match the set size relationship, it is determined that the first status information is that the material exists in the material storage box.

Specifically, in this embodiment, before step S24, the method further includes:

step S01, obtaining the material type stored in the storage box and the structural characteristic information of the second sub light transmission part;

the material types can be classified according to the optical characteristics of the materials, and different material types have different light guide effects (such as reflection, transmission and the like) on light irradiated to the surfaces of the materials. Specifically, in this embodiment, the material types include materials (such as rice, soybean, flour, etc.) capable of reflecting light and materials (such as water, clear soup, snow ice, etc.) capable of transmitting light. The refractive index of the light transmitting material is larger than the refractive index of the second light transmitting sub-portion.

The structural characteristic information specifically refers to characteristic information of a structure of a light guiding effect (such as reflection, projection and the like) of the light path emitted by the second light detection module on the second sub light transmission part.

The structural characteristic information and the material type can be pre-stored parameters or parameters input by a user based on actual use conditions.

And S02, determining the set size relation according to the material type and the structural characteristic information.

Different material types and different structural characteristic information correspond to different set size relationships. Specifically, when the type of the material is a material capable of reflecting light and the structural characteristic information is that the second sub light-transmitting portion is a planar light-transmitting structure, determining that the set magnitude relationship is that the second optical detection signal is smaller than the second set signal threshold; and when the material type is a light-transmitting material and the structural characteristic information is that a total reflection prism is arranged on the second sub light-transmitting part, determining that the set size relationship is that the second optical detection signal is greater than the second set signal threshold value.

The total reflection prism in this embodiment has the same structure as the total reflection prism in the above embodiments, and details are not described herein.

The planar light-transmitting structure specifically refers to a light-transmitting structure having two oppositely disposed light-transmitting planes, and when light is irradiated to one light-transmitting plane, the light can be emitted from the other light-transmitting plane.

When the second sub light-transmitting part is of a plane light-transmitting structure and the storage box is used for materials capable of reflecting light, on the basis of confirming the alignment of the second sub light-transmitting part and the second light detection module based on the placement state information of the storage box, if materials capable of reflecting light exist in the space of the storage box where the second sub light-transmitting part is aligned, the light emitted by the second light detection module is incident into the second sub light-transmitting part and then projected into the corresponding inner space of the storage box, and the materials capable of reflecting light existing in the inner space can emit the light back to the second sub light-transmitting part and projected back into the second light detection module through the second sub light-transmitting part; if there is no material capable of reflecting light in the space of the storage box aligned with the second sub light-transmitting portion, the light emitted by the second light detection module enters the second sub light-transmitting portion and then is projected into the corresponding inner space of the storage box, and the light cannot be reflected because the inner space is air, and cannot return to the second light detection module.

When the second sub light-transmitting part is a total reflection prism and the storage box is used for loading light-transmitting materials, on the basis of confirming the alignment of the second sub light-transmitting part and the second light detection module based on the placement state information of the storage box, if the light-transmitting materials exist in the space of the storage box where the second sub light-transmitting part is aligned, after light emitted by the second light detection module enters the second sub light-transmitting part, the light is transmitted into the light-transmitting material serving as the optically dense medium from the inside of the second sub light-transmitting part of the optically sparse medium, and the light cannot return to the second light detection module due to the light-transmitting of the light-transmitting material; if no light-transmitting material exists in the space of the storage box where the second sub light-transmitting parts are aligned, after the light emitted by the second light detection module enters the second sub light-transmitting parts, the light is transmitted to the air serving as the optically thinner medium from the inside of the second sub light-transmitting parts of the optically denser medium, and the light is totally reflected back to the second light detection module.

Specifically, in this embodiment, when the second optical detection module cannot receive the light emitted by the second optical detection module, the corresponding detection signal is infinite; when the second optical detection module receives the light emitted by the second optical detection module, the corresponding detection signal is close to 0. Based on the above, when the type of the material is a material capable of reflecting light and the structural characteristic information is that the second sub light-transmitting part is a plane light-transmitting structure, a second optical detection signal is smaller than a second set signal threshold value to represent that the material exists in the material storage box; when the material type is a light-transmitting material and the structural characteristic information is that the second sub light-transmitting part is provided with a total reflection prism, a second light detection signal larger than a second set signal threshold value can be adopted to represent that the material exists in the material storage box.

For example, the cooking device is provided with two material storage tanks, one material storage tank is a rice tank and is used for storing rice, the other material storage tank is a water tank and is used for discharging water, the material storage state information can comprise rice storage state information and water storage state information, a second sub light transmission part of the rice tank is of a plane light transmission structure, and a second sub light transmission part of the water tank is a total reflection prism, based on the second sub light transmission structure, a second light detection signal corresponding to the rice tank is defined as Y1, a second light detection signal corresponding to the water tank is defined as Y2, a second setting signal threshold value is B, it can be considered that the rice is not placed in the internal space of the rice tank corresponding to the second sub light transmission part when Y1 & gtB is greater than or equal to Y1, and it can be considered that the rice is placed in the internal space of the rice tank corresponding to the second sub light transmission part when Y1 & ltB is smaller than or equal to B; the water is considered to be placed in the inner space of the water tank corresponding to the second sub light-transmitting part when X2 is more than or equal to B, and the water is considered not to be placed in the inner space of the water tank corresponding to the second sub light-transmitting part when X2 is less than or equal to B.

In this embodiment, different storage boxes correspond to different set size relationships for determining whether materials exist in the storage boxes, wherein the set size relationships are determined by combining structural features of the second sub light-transmitting portions in the storage boxes and the materials stored in the storage boxes, so that whether the materials exist in the storage boxes can be accurately determined based on the set size relationships.

Further, in this embodiment, the material placement status information further includes second status information, and after determining that the first status information indicates that the material exists in the storage bin (in step S241), the method further includes:

step S25, acquiring a set storage amount corresponding to the second optical detection module;

The corresponding relationship between the second light detection module and the set storage amount can be determined in advance according to the capacity of the storage box, the set height of the second light detection module and the like and stored in the memory.

And S26, determining the material storage amount information according to the set storage amount.

Specifically, the acquired set storage amount is used as the material storage amount information.

In this embodiment, when it is determined that there is a material in the storage area of the storage tank corresponding to the second optical detection module based on steps S23 and S24, how much material is stored in the storage tank is determined based on the set storage amount corresponding to the second optical detection module, so as to realize effective representation of the storage amount of the material in the storage tank, and ensure that cooking can be started only when the storage amount of the material in the storage tank meets the cooking requirement of the user, so as to ensure cooking effect.

Further, in this embodiment, the number of the second optical detection modules is plural, the plural second optical detection modules are arranged at intervals along the vertical direction, and the number of the second size relationships corresponding to the second optical detection modules is plural. Based on this, the second optical detection signal that every second detection module corresponds can be to whether there is the material in the corresponding inner space of storage case to carry out the sign, and step S241 includes: if at least one of the second size relationships is matched with the set size relationship, determining that the first state information is that the material exists in the material storage box; step S242 includes: and if the second size relationships are not matched with the set size relationship, determining that the first state information indicates that no material exists in the storage box. Based on the above, the materials in the storage area corresponding to the second optical detection module at any height in the storage box are considered to be stored in the storage box; if the storage areas in the storage boxes corresponding to all the second optical detection modules do not have materials, the storage boxes can be considered as not having materials stored therein.

On this basis, step S25 includes: determining a target detection module among the plurality of second light detection modules; the target detection module is a second optical detection module with a corresponding second size relation matched with the set size relation; and acquiring the set storage amount corresponding to the target detection module. Here, the material storage area in the storage box that the second optical detection module corresponds just can regard as target detection module when having the material, and based on this, along with the difference of the material storage volume in the storage box, can have one or more target detection module. When the number of the set storage amounts corresponding to the acquired target detection modules is multiple, the multiple set storage amounts can be used as the material storage amount information, and one set storage amount can be selected as the material storage amount information. Specifically, when the number of the set storage amount is one, the material storage amount information is determined to be the set storage amount; and when the set storage amount is a plurality of, determining that the set storage amount with the largest numerical value in the set storage amounts is the target storage amount, and determining that the material storage amount information is the target storage amount.

It should be noted that, in other embodiments, when the cooking appliance is not provided with the first light detection module, the second light detection module and the corresponding second sub light-transmitting portion in this embodiment may also be provided, and the material placement state information of the storage bin may be determined according to the related scheme of the second light detection module mentioned in this embodiment.

The target storage amount required for cooking specifically refers to the amount of material required to be placed in the storage box when the amount or shape of food obtained by the cooking operation can meet the user's demand. The target storage amount can be automatically identified based on the cooking type for selection, can be obtained by directly acquiring parameters input by a user, and can also be stored as default parameters.

For example, the storage box is used for placing rice, and when a user needs to cook porridge, the target storage amount can be 150ml; when the user needs to cook, the target storage volume can be 300ml. Based on the above, when the storage box is placed in the cooking appliance and the amount of rice stored in the storage box is at least 150ml, porridge can be cooked, otherwise, the porridge cooking operation cannot be executed; when the storage box is placed in the cooking utensil and the amount of stored rice is at least 300ml, the cooking is started, otherwise, the cooking operation of cooking is not executed. For another example, the storage box is used for placing water, and when a user needs to cook porridge, the target storage amount can be 400ml; when the user needs to cook, the target stock quantity may be 330ml. Based on the above, when the material storage box is placed in the cooking appliance and the water quantity stored in the material storage box is at least 400ml, the porridge can be cooked, otherwise, the cooking operation of the porridge can not be executed; when the storage box is placed in the cooking utensil and the amount of rice stored in the storage box is at least 330ml, the cooking is started, otherwise, the cooking operation of cooking is not executed.

Specifically, the materials stored in the two storage boxes are matched with the materials to be cooked. Based on the above, when the placing state information of the material storage boxes corresponding to the two material storage boxes meets a first set condition and the material placing state information corresponding to the two material storage boxes meets a second set condition, determining that the material storage state information meets a set cooking condition; otherwise, determining that the storage state information does not meet the set cooking condition. The target storage amount corresponding to the water tank can be determined according to the target storage amount of the rice tank.

For example, one storage box is used for containing rice, the other storage box is used for discharging water, the rice cooking and the rice cooking have different rice quantity and water quantity requirements, when a user needs to cook the porridge, the target storage quantity of the rice can be 150ml, the target storage quantity of the water can be 400ml, the rice and the storage boxes used for containing the water are both placed in a cooking appliance, the rice quantity stored in one storage box is at least 150ml, the rice quantity stored in one storage box is at least 400ml, the porridge cooking can be started, and otherwise, the porridge cooking operation cannot be executed; for another example, when a user needs to cook rice, the target storage amount of rice may be 300ml, the target storage amount of water may be 330ml, both the rice and the storage boxes for storing water are placed in the cooking device, and only if at least 300ml of rice is stored in one storage box and at least 330ml of rice is stored in one storage box, the cooking will be started, otherwise, the cooking operation for cooking rice will not be performed.

In the apparatus shown in fig. 5, the processor 1001 may be configured to call the operation control program stored in the memory 1002 and perform the operations of the relevant steps of the operation control method in any of the above embodiments.

Further, the embodiment of the invention also provides a cooking appliance, which can be any electric appliance with a storage box 1 for loading cooking materials, such as an electric cooker, a coffee maker, a food processor, a wall breaking machine and the like.

In one embodiment, referring to fig. 6 to 8, the cooking appliance specifically includes a storage bin 1, a detection device 2 and a controller (not shown) in the above embodiments. The detection device 2 is arranged corresponding to the material storage box 1, the detection device 2 is connected with the controller, and the controller can read detection signals of the detection device 2.

The detection device 2 is specifically a device for detecting the situation of the material storage tank 1 when the material is loaded and/or the situation of the material storage tank 1 when it is placed in an electrical appliance.

The type of the detecting device 2 can be set according to actual conditions, and for example, the detecting device can be one or more of a light detecting device, an elastic detecting device, an image detecting device 2, a weight detecting device 2, a temperature detecting device 2, and the like, which can accurately measure the condition of the material.

The number of the detecting devices 2 can also be set according to actual conditions, and can be 1, 2, 5 or 6. Specifically, in this embodiment, one material storage box 1 is correspondingly provided with at least two detection devices 2, one is used for detecting the placement state information of the material storage box 1, and the other is used for detecting the material storage amount information of the material storage box 1. Wherein the detection device 2 for detecting the material storage amount information of the storage box 1 can be a plurality of to realize the accurate detection of the different material storage amounts of the storage box 1.

In the present embodiment, the detection device 2 is provided outside the magazine 1. In other embodiments, the detection device 2 may be disposed inside the magazine 1, above the magazine 1, or below the magazine 1, according to actual conditions.

This embodiment provides a cooking utensil, corresponds storage case 1 in cooking utensil and is provided with detection device 2 to the controller is connected with detection device 2, and from making the controller can be based on detection device 2's detection signal and realizing automatic accurate discernment to the material condition before the culinary art according to the relevant flow in the above-mentioned operation control method, just begin the culinary art operation when guaranteeing that the material state satisfies the culinary art requirement, with the effective improvement that realizes cooking utensil culinary art effect.

In an embodiment, referring to fig. 7 to 10, the magazine 1 includes a light-transmitting portion 3, the detection device 2 includes a light detection device, the light-transmitting portion 3 is disposed corresponding to the light detection device, and the light detection device is connected to the controller. Specifically, in the present embodiment, the entire case body of the magazine case 1 is a structure of a transparent material (for example, acrylonitrile-styrene copolymer). In other embodiments, the magazine 1 may also be a partially light-transmissive structure, and only the light-transmissive portion 3 is required to be disposed at a position to be detected, and the light-transmissive portion 3 is not required to be disposed at other positions. The light detection means may be an illumination sensor or may be a detection assembly having a light emitter 201 and a light receiver 202. For example, the light detection means may comprise an infrared light emitter 201 and an infrared light receiver 202.

Different storage states of the cooking appliance (such as whether the storage box 1 is placed or not, whether the storage box 1 is used for placing materials or not, and whether the storage box 1 is used for placing materials are different) can form different light detection signals in the light detection device. For example, when the light detection device is an illumination sensor, when a natural light source or an electronic light source irradiates the inside of the material storage box 1, the illumination intensity detected by the illumination sensor is small when the material storage box 1 stores materials; the illuminance that light sensor detected is great when storage case 1 did not deposit the material. Based on this, in this embodiment, the difference of the light detection signal that light detection device's light detection characteristic, the printing opacity characteristic of storage case 1, the printing opacity characteristic of material etc. difference formed in light detection device is combined to can realize the accurate discernment detection to the cooking utensil storage condition through the light detection signal.

In an embodiment, referring to fig. 7 to 11 and 14, the light-transmitting portion 3 includes a total reflection triangular prism, and when the material storage space corresponding to the light-transmitting portion 3 is empty, the light emitted by the light detection device enters the total reflection triangular prism, and enters the light detection device after total reflection occurs. Specifically, the optical detection device includes light emitter 201 and light receiver 202, when optical detection device and total reflection prism counterpoint set up, the light that light emitter 201 launched enters into the total reflection prism, if do not have the material in the material parking space of storage box 1 with 3 counterpoints of printing opacity portions, then the air belongs to the light sparse medium in the storage box 1, and printing opacity portion 3 belongs to the optical density medium for the solid structure, therefore the light of inciding in the total reflection prism can take place the total reflection, the reflection light path can enter into light receiver 202 and form corresponding signal. Based on this, when the light detection device and the total reflection prism of the storage box 1 are not aligned or the storage box 1 is placed with a transparent material (such as water) to form an optically dense medium, the light incident into the total reflection prism will not be totally emitted but will be transmitted into the storage box 1, and the light receiver 202 will not detect the reflected light. Based on this, can realize whether having deposited the printing opacity material condition through the printing opacity characteristic of total reflection prism to storage case 1's the condition of placing, storage case 1 internal correspondence light detection device and realize accurate discernment.

In one embodiment, referring to fig. 7 to 11, and fig. 14, the light detection device includes a light emitter 201 and a light receiver 202, wherein the light emitter 201 is spaced apart from the light receiver 202; a surface of the total reflection prism facing the optical transmitter 201 and the optical receiver 202 is defined as an incident surface, a direction in which the optical transmitter 201 and the optical receiver 202 extend is defined as a reference direction, and a width d1 of the incident surface along the reference direction is within an interval range of [5mm,9mm ]. Specifically, total reflection prism has first surface, second surface and third surface, first surface is located storage case 1's surface, the second surface with the third surface intersects perpendicularly, and is located in storage case 1, the second surface has relative first limit and the second limit that sets up, the third surface has relative third limit and the fourth edge that sets up, first limit with the third edge is connected. The third surface is the surface of storage case 1, and first surface and second surface are the internal surface of storage case 1, and light detection device locates the outside of storage case 1, and sets up with the third surface interval. When the storage area corresponding to the optical detection device is empty, the light emitted by the optical detection device is vertically incident to the first surface, and is reflected on the second surface and the third surface in sequence, and finally the reflected light is incident to the optical receiver 202. The second surface and the third surface are perpendicularly intersected through the first edge and the third edge. In the present embodiment, the width d1 of the incident surface in the reference direction may be 7mm; in other embodiments, the width d1 of the incident surface along the reference direction may also be selected to be 6mm, 5.5mm, 7.5mm, 8mm, 8.5mm, and the like according to actual requirements. In this embodiment, since the incident surface is along when width d1 of reference direction is too small, incident light and reflected light in the total reflection prism easily influence each other, lead to storage state information detection's result inaccurate, and the incident surface is along when width d1 of reference direction is too big, light easily diverges and causes light loss, through the accuracy that influences storage state information detection result. Based on this, controlling the width d1 of the incidence surface along the reference direction within the interval range of [5mm,9mm ] can be beneficial to ensuring that the material storage state information of the cooking appliance can be accurately obtained based on the optical detection signal.

Further, with reference to fig. 14, a distance d2 between the light emitter 201 and the light receiver 202 is smaller than or equal to a width d1 of the incident surface along the reference direction, so that the light receiver 202 can effectively detect the reflected light, and the accuracy of detecting the stock state information is further ensured.

Further, in an embodiment, referring to fig. 13 to 14, the light detecting device further includes a light emitter 201, a light receiver 202, a first light focusing element 41, and a second light focusing element 42, wherein the first light focusing element 41 is disposed between the light emitter 201 and the light-transmitting portion 3, and the second light focusing element 42 is disposed between the light receiver 202 and the light-transmitting portion 3. Because the light is inevitably diffused to a certain degree in the propagation process, when the light emitter 201 emits the light to the light transmission part 3, the light can be ensured to be incident into the light transmission part 3 under the action of the first light gathering part 41, and especially when the light transmission part 3 is a total reflection prism, the light can be ensured to be accurately incident into the total reflection prism at an incident angle of 90 degrees; the second light-condensing element 42 can ensure that the reflected light can be deflected toward the light receiver 202, and the light receiver 202 can effectively collect the reflected light. Based on this, the arrangement of the first light gathering part 41 and the second light gathering part 42 is beneficial to further ensure that the optical detection signal detected by the optical detection device can accurately reflect the material state.

Specifically, referring to fig. 13 to 14, a first inclined plane is disposed on one side of the first light gathering member 41 facing the light emitter 201, a second inclined plane is disposed on one side of the second light gathering member 42 facing the light receiver 202, the first inclined plane and the second inclined plane are arranged at an included angle, and an angular bisector of the included angle between the first inclined plane and the second inclined plane is located between the light emitter 201 and the light receiver 202. The light emitted from the light emitter 201 is refracted by the first slope and then enters the light-transmitting portion 3 from the first light-focusing member 41, and the light emitted from the light-transmitting portion 3 enters the second light-focusing member 42 and then is refracted by the second slope and then enters the light receiver 202.

With reference to fig. 12 to 13, an included angle α between the first inclined surface and the second inclined surface is within an interval [130 °,180 ° ]. In the present embodiment, the included angle α between the first inclined surface and the second inclined surface is 150 °.

The first sub light-transmitting part 31 of the first material storage box 11 is a total reflection prism, and the second sub light-transmitting part 32 is a plane light-transmitting structure. Based on this, the light detection signal of the first light detection module 21 of the first storage box 11 can be used to represent whether the first storage box 11 is placed in the cooking utensil, and the light detection signal of the second light detection module 32 of the second storage box 12 can be used to represent whether the material and the storage amount of the material are present in the first storage box 11.

Because the first light detection module 21 corresponding to the first storage box 11 is fixedly arranged in the cooking appliance, and the first storage box 11 is detachable, when the first storage box 11 is not placed in the cooking appliance, no total reflection prism of the first storage box 11 reflects the light emitted by the first sub-detection module 21, the light emitted by the first light detection module 21 cannot be reflected back to the first light detection module 21 corresponding to the first storage box 11, and the first light detection module 21 cannot detect a light reflection signal thereof; when the first storage box 11 is placed in the cooking appliance, the total reflection prism reflects light emitted by the corresponding first light detection module 21, so that the light emitted by the first light detection module 21 corresponding to the first storage box 11 is reflected back to the first light detection module 21, and the first light detection module 21 corresponding to the first storage box 11 can detect the light reflection signal.

Since the material stored in the second material storage box 12 is transparent to light, when the second material storage box 12 is located in the cooking utensil, the light emitted by the second light detection module 22 corresponding to the second material storage box 12 enters the corresponding total reflection prism, and when no material is stored in the area of the second material storage box 12 corresponding to the second light detection module 22, the light is totally reflected in the total reflection prism, and the reflected light returns to the second light detection module 22, when a transparent material is stored in the area of the second material storage box 12 corresponding to the second light detection module 22, under the transparent action of the transparent material, the light is not totally reflected in the total reflection prism, and the second light detection module 22 cannot detect the reflected light signal, so that accurate identification of the material stored in the second material storage box 12 can be achieved based on the difference between the detection signals of the second light detection module 22 corresponding to the second material storage box 12 and the material state reflected by the detection signals detected by the second light detection module 22 corresponding to the second material storage box 12.

In this embodiment, when the storage tanks 1 for loading different materials are arranged in the cooking appliance, the first light detection module 21 to the second light detection module 22 are correspondingly arranged, so that the placing states of the different storage tanks 1 in the cooking appliance and the storage amounts of the loaded different materials are accurately identified, and when the cooking appliance needs to cook different materials cooperatively, the corresponding storage states of the various materials can enable the cooking effect of the cooking appliance to meet the user requirements.
