Hereinafter, in conjunction with the accompanying drawings, a method for automatically adjusting the heat retention performance of a cooking appliance, an apparatus for automatically adjusting the heat retention performance of a cooking appliance, and a cooking appliance according to an embodiment of the present application will be described.

In an embodiment of the present application, the cookware may be a detachable cooker, and the detachable cooker may be a detachable electric rice cooker or a detachable electric pressure cooker.

As shown in FIG. 1 , the cooking appliance according to the embodiment of the present application measures the weight of the base 10 , the appliance body 20 , and the appliance body 20 , and puts the food into the appliance body 20 . and a weight measuring device 30 for obtaining weight information.

The instrument body 20 is suitable for mounting on the base 10 and is detachable with respect to the base 10 . In addition, the city household electricity can be directly connected to the base 10 , but the urban household electricity is not directly connected to the appliance body 20 . When the appliance body 20 is placed on the base 10 , the base 10 provides power or thermal energy for cooking for the appliance body 20 . Specifically, the heating device of the base 10 provides power for cooking to the appliance body 20 on the base 10 by wireless or a power supply method through a terminal, or by heating plate heating, microwave heating or electromagnetic heating, etc. Heat energy for cooking is provided to the appliance body 20 on the base 10 .

In one embodiment of the present application, the weight measuring device ( 30) may install a weight sensor 31 such as a photoelectric weight sensor, an electromagnetic weight sensor, a capacitive weight sensor, a resistance strain weight sensor, and the like, and a specific type may be selected according to actual demand. As shown in FIG. 2 , a plurality of weight sensors 31 may be installed, and the weight sensors 31 may be installed under the instrument body 20 .

As shown in Figure 3, when the appliance body 20 and the base 10 constitute a complete cooking appliance (that is, when the user puts the appliance body 20 on the corresponding base 10) , the weight measurement device 30 effectively avoids measuring the weight of the base to measure the weight of the instrument body 20 through the weight sensor 31, and reduces the weight measurement distance of the weight measurement device, thereby measuring the weight improve accuracy.

As shown in FIG. 3 , a supporting position may be installed in the lower portion of the instrument body 20 , and the weight sensor 31 is installed corresponding to the supporting position. Here, there may be four support positions, and the four support positions are respectively installed to correspond to four corners of the lower part of the instrument body 20 , and the weight sensors 31 may be four, and four weight sensors 31 . may be installed to correspond to each of the four support positions, and accordingly, the weight information of the instrument body 20 obtained by each weight sensor 31 basically matches, thereby improving the accuracy of weight measurement.

The above embodiment is only one specific embodiment of the present application, and the measurement of the weight of the instrument body 20 may be implemented in other ways, but will not be described in detail herein.

4 is a flowchart of a method for automatically adjusting the warming performance of a cooking appliance according to an embodiment of the present application. As shown in FIG. 4 , the method for automatically adjusting the warming performance of a cooking appliance according to an embodiment of the present application includes the following steps. In other words:

S1, when the cookware enters the keep warm state, the initial weight of the rice inside the appliance body is acquired through the weight measuring device, and the lid opening and closing operation of the cookware is detected to determine whether the cookware has a lid opening operation during the warming process. decide whether

Specifically, when power is connected to the cookware, the cookware enters the standby state, the user selects the cooking function according to their own demand, and when the user selects the function, the amount of rice to be added is presented, and the user presents After adding the appropriate amount of rice and water, press the start button, and the cookware starts to cook the rice. In general, the cookware automatically enters the keep warm state after completing cooking. After the cookware enters the keeping warm state, two situations may occur. The first situation is a situation in which the user frequently opens and closes the upper lid of the cookware when the user eats during the warming process, in other words, A situation in which the upper lid is opened and closed frequently may occur, and the second situation is a situation in which the user does not open the upper lid of the cookware all the time between two meals during the warming process. There may be situations in which opening and closing operations do not occur. In order for the rice after warming to achieve the same effect as freshly cooked rice, different warming methods should be used in preparation for the above two situations.

Specifically, after the cookware enters the keep warm state, the initial weight (m1) of the rice inside the appliance body is acquired and recorded through the weight measuring device, and the lid opening operation of the cookware is detected in the process of keeping the cooker warm. It may be determined whether a lid opening operation exists, and whether an upper lid opening operation exists in the cooking appliance may be determined according to existing technology. If there is an upper lid opening operation in the cooking utensil within a certain period of time (eg, within 1 hour), the warming control method of the situation in which the lid opening operation corresponding to the first situation exists is performed, otherwise, the second situation Executes the warming control method in a situation in which the lid opening operation corresponding to ' does not exist.

S2, if there is a lid opening operation in the cooking appliance during the warming process, the actual weight of the rice inside the appliance body is acquired in real time through the weight measuring device, and it is determined whether the current actual weight is greater than the initial weight.

S3, if the current actual weight is greater than the initial weight, when the temperature inside the cookware reaches the preset reference temperature keeping temperature, the target temperature of the heating appliance's upper lid and the heating power of the upper lid of the cookware are reduced, Controls so that the target temperature for keeping the lower part of the cooker and the power consumed for heating the lower part of the cookware are maintained as they are.

Specifically, it is possible to further classify the warming conditions in the warming process of the cookware. For example, in the first situation, the user frequently opens and closes the upper lid of the cookware during the meal process to unpack the rice from the appliance body. Not only may there exist, but there may also exist a situation where cold rice is put into the appliance body, that is, in the first situation, the amount of rice inside the appliance body increases (eg, when cold rice is put inside the appliance body and eaten at the next meal) ) or decreased (by unpacking rice at a meal). In order to improve the taste of rice after warming, different warming methods can be used for these two situations.

Specifically, if there is an opening operation in the warming process of the upper lid of the cookware and the actual weight (m2) of the rice inside the appliance body acquired in real time through the weight measurement device is greater than the initial weight (m1), any adjustment According to a normal warming process, the temperature inside the appliance body may reach a preset reference warming temperature (eg, a warming temperature that can be reached by the existing technology) without even doing it. Then, after the temperature inside the appliance body reaches a preset reference keeping temperature, the target temperature of the upper lid of the cookware and the heating power of the upper lid of the cookware are controlled to decrease so that the surface of the rice becomes dry or yellow. At the same time, it is possible to maintain the warming temperature of the lower part by controlling the heating power of the lower part of the cookware to be maintained as it is.

In addition, in one embodiment of the present application, when the lid opening operation is present in the cooking utensil during the warming process, if the current actual weight is less than the initial weight, The heating power is increased, the heating power of the lower part of the cookware is decreased, and the heating target temperature of the lower part of the cookware is controlled to be maintained as it is.

Specifically, if there is an opening operation in the warming process of the upper lid of the cookware and the actual weight (m2) of the rice inside the appliance body acquired in real time through the weight measurement device is smaller than the initial weight (m1), the It controls the heating target temperature of the upper lid and the heating power of the upper lid of the cookware to increase, the heating power for the lower part of the cookware is decreased, and the target keeping temperature of the lower part of the cookware is maintained as it is, and accordingly, the upper and lower A small temperature difference is ensured to prevent the formation of condensate.

In addition, FIG. 5 shows a logical process of a method for automatically adjusting the warming performance when a lid opening operation is present in the warming process of the cookware. As shown in FIG. 5 , automatic heating performance adjustment when a lid opening operation exists The method includes the following steps. In other words:

S101, start warming.

S102, when the warming is started through the weight measuring device, the weight (m1) of the rice inside the appliance body is acquired and recorded.

S103, the actual weight (m2) is recorded by continuously acquiring the weight of the rice inside the appliance body through the weight measuring device.

In S104, it is determined whether there is a case where m2>m1. If present, step S105 is performed, and if not, step S108 is performed.

S105, first, according to the normal warming process, the temperature inside the appliance body reaches the reference warming temperature.

S106, after reaching the reference warming temperature, the target temperature of the top cover is decreased.

S107, reduce the heating power of the upper lid.

In S108, it is determined whether there is a case where m2 < m1. If present, step S109 is performed, and if not, step S112 is performed.

S109, increase the target temperature for keeping the top lid warm.

S110, increase the heating power of the upper lid.

S111, reduce the heating power of the lower part.

S112, it is determined whether the nearest time at which the lid opening operation occurs has elapsed for more than one hour. If more than one hour has elapsed, step S113 is performed; otherwise, the flow returns to step S103.

S113, enters the warming process with the lid not opened.

In one embodiment of the present application, when the lid opening operation does not exist in the cooking appliance during the warming process, the actual weight of the rice inside the appliance body is acquired in real time through the weight measuring device, and the difference value between the initial weight and the current actual weight to determine whether the difference between the initial weight and the current actual weight is greater than a first preset threshold value by obtaining controlling the target keeping temperature and heating power of the lower part of the cookware to be reduced and maintaining the target keeping temperature of the upper lid of the cookware and heating power of the upper lid of the cookware as they are; If the difference between the initial weight and the current actual weight is less than or equal to the first preset threshold, the heating target temperature of the lower part of the cookware and the heating power of the lower part of the cookware are maintained as they are, and the heating target temperature of the upper lid of the cookware is maintained as it is. and the heating power of the upper lid of the cookware is controlled so that it is maintained as it is.

Specifically, in the case of the second situation, if the user does not open the top lid of the cookware all the time during the warming process, the process of evaporating moisture inside the appliance body, condensing it on the upper lid, and flowing back into the appliance body is continuously repeated. . Here, the process of evaporating the moisture and the process of condensing on the upper lid are two different physical change processes, so the two situations can be further distinguished, in other words, different warming methods can be used.

Specifically, if there is no lid opening operation in the cooking appliance during the warming process, the actual weight (m2) of the rice inside the appliance body is acquired and recorded in real time through the weight measuring device, and the initial weight (m1) and the current actual weight (m2) is obtained, and the difference between the initial weight (m1) and the current actual weight (m2) is a first preset threshold value (n1) (n1 can be adjusted in advance according to the entire heating system, generally 2 It is judged whether or not it is greater than the amount of warming evaporation for ~4 hours). When the difference value between the initial weight (m1) and the current actual weight (m2) is greater than the first preset threshold value (n1), the heating power of the lower part of the cookware is reduced and the target temperature of the lower part of the cookware is reduced, so that the inside of the appliance body At the same time, control so that the heating target temperature of the upper lid of the cookware and the heating power of the upper lid of the cookware are maintained as they are, otherwise, the heating target temperature of the lower part of the cookware and the lower part of the cookware are maintained. The heating power is maintained as it is, and the heating target temperature of the upper lid of the cookware and the heating power of the upper lid of the cookware are maintained as they are. In other words, the normal warming process is maintained and the temperature is not controlled.

In addition, in one embodiment of the present application, the target warming target temperature of the lower portion of the cookware and the heating power of the lower portion of the cookware are reduced, and the target keeping temperature of the upper lid of the cookware and the heating power of the upper lid of the cooker are maintained as they are. After controlling to be so, the actual weight change value of the rice inside the appliance body is obtained, and it is determined whether the actual weight change value of the rice inside the appliance body is greater than a second preset threshold value, and the actual weight of the rice inside the appliance body When the change value is greater than the second preset threshold, the heating power of the lower part of the cookware is increased and the heating power of the lower part of the cookware is increased, the heating power of the upper lid of the cooker is increased, and the heating power of the upper cover of the cooker is increased. The temperature is controlled to be maintained as it is, and when the actual weight change value of the rice inside the appliance body is less than or equal to the second preset threshold value, the heating target temperature of the lower part of the cookware and the heating power of the lower part of the cooker are maintained as they are, The control is performed so that the target temperature for keeping the upper lid of the cookware and the heating power of the upper lid of the cookware are maintained as they are.

Specifically, after controlling so that the target keeping temperature of the lower part of the cookware and the heating power of the lower part of the cookware are reduced and the target keeping temperature of the upper lid of the cookware and the heating power of the upper lid of the cooker are maintained as they are, the weight is measured The device acquires and records the actual weight (m3) of the rice inside the appliance body in real time, and calculates the actual weight change value of the rice inside the appliance body, that is, m3-m2, so that the actual weight change value m3-m2 is It is determined whether or not it is greater than the second preset threshold value n2 (the value of n2 may be the weight of water that has formed within 2 to 4 hours, specifically, it can be adjusted according to the actual dripping situation). If the actual weight change value m3-m2 is greater than the second preset threshold value (n2), the heating power of the upper lid of the cookware is increased (if side heating is possible, the side heating power can be appropriately increased) At the same time to achieve the effect of evaporating water quickly, the heating power of the lower part of the cookware is increased and the heating power of the lower part of the cookware is increased, and the heat preservation target temperature of the upper lid of the cookware is maintained as it is, otherwise, The control is performed so that the target keeping temperature of the lower part of the cookware and the heating power of the lower part of the cookware are maintained as they are, and the target keeping temperature of the upper lid of the cookware and the heating power of the upper lid of the cookware are maintained as they are. Maintain the process and do not control the temperature.

In addition, FIG. 6 shows a logical process of the method for automatically adjusting the thermal insulation performance when the lid opening operation does not exist in the thermal insulation process of the cookware, and as shown in FIG. 6 , the thermal insulation performance when the lid opening operation does not exist The automatic adjustment method includes the following steps. In other words:

S201, start warming.

S202, when the warming is started through the weight measuring device, the weight of the rice inside the appliance body is acquired and the initial weight (m1) is recorded.

S203, the actual weight (m2) is recorded by continuously acquiring the weight of the rice inside the appliance body through the weight measuring device.

In S204, it is determined whether there is a case where m1-m2>n1. If present, step S205 is performed, and if not, step S207 is performed.

As described above, in the method for automatically adjusting the thermal insulation performance of the cooking appliance according to the embodiment of the present application, the thermal insulation performance of the rice is further improved by controlling the thermal insulation temperature and power consumption by linking the weight of the rice inside the appliance body to the heating process. It has a relatively high use value because it effectively avoids the surface of the rice from drying out, turning yellow, or scorching, so that the rice after warming is the same as freshly cooked rice.

In actual use, the user often cooks a larger amount of rice to keep it warm or for other purposes when cooking using a cooking utensil, in other words, there is often leftover rice, and the remaining rice is spoiled if not handled in a timely manner. Or the taste decreases, which has an unpleasant effect on the user. In consideration of this, in an embodiment of the present application, after the cookware completes cooking and enters the warming state, whether there is rice remaining inside the appliance body according to the actual weight of the rice inside the appliance body acquired in real time , and if there is rice remaining inside the appliance body and the duration reaches a first preset time, the cooking appliance is controlled to generate the remaining rice notification information.

Here, the step of determining whether there is leftover rice inside the appliance body according to the actual weight of the rice inside the appliance body acquired in real time includes a change in the weight of the rice inside the appliance body according to the actual weight of the rice acquired in real time acquiring a situation; And, when it is determined that the actual weight of the rice inside the appliance body is maintained within the second preset time and is greater than or equal to the preset weight according to the change in the weight of the rice, it is determined that there is rice remaining inside the appliance body, Here, the second preset time is smaller than the first preset time, and the first preset time, the second preset time, and the preset weight may specifically determine a reference value according to an actual situation. For example, the first preset time may be 12h, the second preset time may be 1h, and the preset weight may be 100g.

Specifically, after the cookware completes cooking and enters the warming state, the initial weight (m1) of the rice inside the appliance body is acquired through the weight measuring device, and the actual weight m3 of the rice inside the appliance body is acquired in real time. Acquire the change in the weight of the rice inside the main body in real time.

After acquiring the weight change situation of the rice inside the appliance body in real time, it is determined whether there is food remaining inside the appliance body according to the weight change situation. For example, after cooking the rice, the user eats shortly thereafter. The weight of the rice inside the appliance body constantly changes during the meal process, but after a certain period of time has elapsed, for example, after the user has finished eating. The weight of the rice inside the appliance body is no longer changed, in this case two situations can exist. The first situation is a situation where there is no rice left inside the appliance body, and the weight obtained at this time is approximately 0 g. Therefore, it is determined whether there is remaining rice inside the appliance body by determining whether the change in the weight of the rice inside the appliance body and the weight of the remaining rice within a predetermined time is greater than a predetermined value.

For example, assuming that the initial weight obtained after completing cooking is 1000 g and the user ate 800 g of rice during the meal, the weight of the rice inside the appliance body within a certain time after the user has finished eating is 200 g (pre-set in advance). weight greater than 100 g), and in this case, it can be determined that there is remaining rice inside the appliance body. Then, it is determined that there is leftover rice inside the appliance body, and the time is recorded, or the time is continuously recorded from the base of the current time, and when a certain time (eg, 12h) is reached, the inside of the appliance body is Recognizing that the storage time of the remaining rice is relatively long, the cooking appliance is controlled to generate notification information of the remaining rice. For example, the user is notified through a buzzer, a voice, or a display lamp to prevent the user from damaging the physical health by forgoting the leftover rice for a long time and not processing it, such as losing the taste of the rice, changing the quality of the rice, or giving off an odor.

In addition, Figure 7 is a flowchart of a method for detecting the remaining rice of the cooking appliance according to an embodiment of the present application. As shown in FIG. 7 , the method for detecting the remaining rice of the cooking appliance includes the following steps. In other words:

S301, reset the weight measurement data, select the cooking function and rice type.

S302, the user is presented with the amount of rice to be added, and the user adds the corresponding amount of rice and water according to the suggestion.

S303, start cooking.

S304, cooking is completed.

S305, warming or cooking ends.

S306, after completion of cooking, the initial amount of rice (m1) is calculated by collecting the weight measurement data of the weight measurement device.

S307, after the user eats a certain amount of rice (m4), the remaining amount of rice is n3=m1-m4.

S308, it is determined whether n3≥100g is continuously changed for a certain period of time.

S309, it is determined whether the remaining rice storage time t ≥ the set remaining rice storage time t2 is satisfied. If "Yes", step S310 is performed, and if "No", step S309 is performed.

S310, notify the user so that the user can process in time.

Here, what needs to be explained is that the remaining rice storage time is generally set to a relatively long time, for example 12h in the above example, but there may be situations in which the user eats during this period. , and the other situation is to eat the leftover rice. In the first situation, you can delete the current record and start cooking again, but in the second situation, if you eat the remaining rice, the user can select cooking again from the base of the remaining rice. The period of validity is much shorter than that in one case. Therefore, in this case, the current record is not erased and the time is recorded continuously on this basis. For example, in preparation for this, a button to cook leftover rice is added so that the user presses the button first before cooking to maintain the currently recorded time and cook again, and also after the user eats in the above-mentioned manner. It judges whether there is leftover rice, and if there is, it continuously records the time on the basis of the time recorded before that, so that the remaining rice notification is not correct by using the remaining rice to cook again, and Avoid the effect of rice on the user's health.

In addition, since the storage time of the remaining rice is set to a relatively long time, a battery is installed inside the cooking utensil to supply power to the remaining rice notification module to prevent a situation in which the user cannot be notified when the city household electricity is cut off. It further improves the reliability of the Bob notification. In addition, by adding a corresponding setting button, the first preset time and preset weight can be set to implement personalized customization and meet the actual needs of various users and different regions. For example, some users cannot tolerate leftover rice for more than 6 hours, and for example, the storage time of leftover rice in a hot and humid area is much shorter than that in a low temperature dry area. Therefore, it is possible to meet the actual demand of the user by adding the corresponding setting button.

In addition, in one embodiment of the present application, the cooking appliance performs wireless communication with the mobile terminal, and when there is rice remaining inside the appliance body and the duration reaches a first preset time, the remaining rice through the mobile terminal Generates notification information.

Specifically, when the cooking utensil is connected to the user's mobile terminal through a network and is connected to the network, the remaining rice notification information may be transmitted to the user in real time through the mobile terminal to notify the user. For example, in the case of an office worker, if you cook too much rice in the morning and do not eat it all, you may be able to buy vegetables and prepare a meal again without even thinking about the fact that there is rice left at home after a busy day. When you come home and find that there is leftover rice in the cookware, you can think about whether to throw away the rice or cook a new one, or you can eat outside and forget the fact that there is rice left at home and eat it the next morning because you cannot handle it in time. If you find leftover rice in cooking utensils, you have to spend a lot of time cleaning moldy and stinky food, which makes you feel bad and lowers the user experience. Therefore, if the user is notified in time through the mobile terminal, whether the user is at home or outside, the situation of remaining rice can be grasped in real time, and the situation as described above can be effectively avoided by selecting according to the situation of remaining rice. .

In another embodiment of the present application, the cooking utensil communicates with the cloud server, and when there is rice remaining inside the unit body and the duration reaches a first preset time, the cooking utensil transmits the remaining rice information to the cloud It is transmitted to the server, and the cloud server statistically and analyzes the remaining rice information, generates rice amount notification information according to the analysis result, and transmits the rice amount notification information to the cooking utensil when cooking with the cooking utensil.

Specifically, although the user is presented with the amount of rice and water to be added when the user selects the cooking function, this suggestion presents the upper and lower limits of the amount of rice and water to be added, and the proportional relationship between rice and water, and the user's actual meal amount It is not decided based on this, and the user himself cannot accurately grasp the actual amount of rice required, so after cooking, there is often a lot of rice left.

In the embodiment of the present application, when there is food left inside the appliance body and the duration reaches a first preset time, that is, when the cookware kills the remaining rice notification information, the food leftover information is transmitted to the cloud server. After transmitting and analyzing the leftover food information through the cloud server, notification information of the amount of food to be cooked is generated according to the analysis result. For example, if the weight of the remaining rice three times in a row exceeds a certain weight value (for example, 200 g), the amount of cooking that the user does not necessarily need (for example, the remaining cold rice is more preferable when making fried egg rice) In order to avoid wastage by appropriately reducing the amount of food to be cooked, it generates notification information of the amount of food to be cooked, such as "There is too much rice left. Be careful about saving", and sends the notification information to the cooker when cooking is resumed.

In addition, in the above examples, the case of cooking rice is all taken as an example, but the present application is similarly applied to porridge, ribs, soup, cake, yogurt, and the like, and will not be described in detail here.

Therefore, in the method for detecting leftover rice in the cooking appliance according to the embodiment of the present application, the weight value of the food inside the appliance body is obtained in real time through the weight measurement data collected through the weight measurement device after the cooking appliance completes cooking, It is determined whether there is food left inside the appliance body according to the weight value obtained in real time. By generating notification information to notify the user to process it in a timely manner, it is prevented that the remaining rice storage time is too long and the taste of the rice is deteriorated or deteriorated, causing a bad odor and affecting the health of the user.

In addition, an embodiment of the present application provides a non-transitory computer-readable storage medium in which a computer program is stored, and when the program is executed by a processor, a method for automatically adjusting the warming performance of the cooking appliance is implemented.

The non-transitory computer-readable storage medium according to an embodiment of the present application performs the automatic control method of the heat preservation performance of the cooking appliance, thereby more accurately improving the heat preservation performance of the rice and effectively avoiding the surface of the rice from drying out, yellowing, or rotting.
