Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, some configurations which are not related to the gist of the present invention may be omitted or compressed, but the configurations omitted are not necessarily those not necessary in the present invention, and they may be combined by a person having ordinary skill in the art to which the present invention belongs. .

FIG. 1 is a view for explaining a scale integrated cooking device using a smart device according to an embodiment of the present invention. FIG. 2 (a) is a schematic view for explaining a base plate, a load cell and a heating means in the cooking apparatus shown in FIG. FIG. 2B is a block diagram for explaining the detailed configuration of the cooking apparatus shown in FIG. 1. FIG.

1 and 2, a balance-type cooking apparatus 10 (hereinafter referred to as "cooking apparatus") using a smart device according to an embodiment of the present invention includes a main body 11, a key input unit 12, The sensor 13, the vibration sensor 14, the base plate 15, the load cell 16, the heating means 17, the screen output unit 18, the audio output unit 19, 21 and a memory 22. [

Other components of the cooking apparatus 10 are mounted on the main body 11 and a key input unit 12, a sound pressure sensor 13, a screen output unit 18 and an audio output unit 19 are provided on the front surface.

The key input unit 12 is for receiving a user's command. The user can load the recipe information stored in advance in the memory 22 through the key input unit 12, or perform stepwise material survey confirmation or step- Or a setting command such as a feeding mode can be input.

The sound pressure sensor 13 is for recognizing a sound, and can recognize the rattle sound of the lid of the cooking container 40 placed on the receiving plate 15 or recognize the sound of the baby. The sound information recognized by the sound pressure sensor 13 is transmitted to the control unit 21. The control unit 21 analyzes the sound information to determine whether a sound of a specific pattern has occurred, and then performs control. The user can input a user command by voice instead of the key input unit 12. At this time, the voice command of the user can be obtained from the sound pressure sensor 13. [

The vibration sensor 14 is for recognizing the vibration. For example, the vibration sensor 14 can recognize the vibration generated when the lid of the cooking container 40 put on the receiving plate 15 swings.

The reason why the sound or vibration generated when the lid of the cooking container 40 is tumbled by the sound pressure sensor 13 or the vibration sensor 14 is to recognize that the overflow phenomenon occurs in the cooking process, It is possible to check the overflow phenomenon even if only one of them is detected. Therefore, any one of the multi-surface sound pressure sensor 13 and the vibration sensor 14 for the function alone may be excluded. However, if both the sound pressure sensor 13 and the vibration sensor 14 are used, a more accurate overflow phenomenon can be confirmed.

The support plate 15 is installed on the upper portion of the main body 11 and is cooked while the cooking vessel 40 is placed on the support plate 15.

The load cell 16 serves as an electronic balance by measuring the weight of the material placed in the container or container placed on the receiving plate 15. [ The weight information of the container or material measured by the load cell 16 is transmitted to the control unit 21. [

The heating means 17 provides heat to the container placed on the support plate 15. In this embodiment, the induction system for providing heat by an electromagnetic induction method is mounted. 2, the heating means 17 may be a coil forming an alternating magnetic field when an alternating current is supplied.

Of course, it is also possible to apply an electric range (highlighting) or a gas range heating means 17 according to the embodiment. When the electric range system is applied, the heating means 17 may be a coil for heating the bed plate 15 by generating heat when power is supplied. Further, when the gas range system is applied, the heating means 17 may be a crater for generating a fire using gas as a raw material. Of course, in the case of the gas range system, the shape of the bed plate 15 must be changed so that the flame can be directly transferred to the cooking vessel 40.

The screen output unit 18 is provided for outputting related information necessary for a cooking process such as a setting menu or weight information of a measured material.

The voice output unit 19 is provided for outputting voice announcements and alarms necessary for the cooking process.

The local communication means 20 is provided for connecting a communication channel with a smart device 30 such as a smart phone, a tablet PC, a smart TV, a smart refrigerator, a computer, and transmitting / receiving necessary information. For example, the short-range communication unit 20 may connect the communication channel using Bluetooth or Wi-Fi, and receive the recipe information or the user command from the smart device 30. [

The control unit 21 processes the weight information measured by the load cell 16 to be output through the screen output unit 18 or outputs the recipe information received from the smart device 30 and stored in the memory 22 in a step- Or a setting menu for allowing the user to select a user command, or to adjust the thermal power of the heating means 17 according to the set recipe information. The control unit 21 analyzes the sound information measured by the sound pressure sensor 13 or the vibration sensor 14 and controls the operation of the heating unit 17 when a specific event occurs.

The memory 22 is provided for storing information necessary for the cooking process or information set by the user. For example, when recipe information or setting information is received from the smart device 30 via the short-range wireless communication means, the setting information may be stored in the memory 22, and the setting information directly input through the key input unit 12 may be stored in the memory 22 . The information stored in the memory 22 is read by the control unit 21 and output through the screen output unit 18 or used for controlling the heating means 17. [

The cooking apparatus 10 according to the embodiment of the present invention described above will be further specified through an example of the operation process of the cooking apparatus described in Figs. 3 to 5 below.

Fig. 3 is a flowchart for explaining an example of the operation process of the cooking appliance shown in Fig. 1. Fig. More specifically, FIG. 3 shows an example in which the cooking process is automatically performed in accordance with the recipe information set in the control unit 21 of the cooking apparatus 10.

The user can retrieve the recipe information through the smart device 30. When the recipe information retrieved from the smart device 30 is received by the local communication means 20 of the cooking appliance 10, The stored recipe information may be stored in the memory 22 or may be set to start cooking (S305). At this time, a dedicated application that can be interlocked with the cooking apparatus 10 according to the embodiment of the present invention is installed in the smart device 30, and the recipe information is retrieved through the dedicated application and the recipe information is received , The recipe information includes control information that allows the cooking apparatus 10 to control the thermal power in steps. Of course, such exclusive application and dedicated recipe information for setting the cooking appliance 10 can be provided by the supplier who supplied the cooking appliance 10 or a company associated therewith.

When the recipe information stored in the memory 22 is loaded or the recipe information received via the local communication means 20 in real time is set in the control unit 21, the user places the cooking container 40 on the base plate 15, (Balance) is initialized (S310). If the heating means 17 of the cooking apparatus 10 provides heat in an induction manner, the cooking vessel 40 also needs to use a dedicated vessel for the induction range. The reason for initializing the load cell 16 is that the weight of the cooking container 40 should be excluded from the weight of the food.

Then, the control unit 21 processes the cooking-related information, that is, the recipe information, in a step-by-step manner through the screen output unit 18 in accordance with the recipe information. For example, if the ramen is cooked, a message of 'Prepare 550 ml (or 550 g) of water' can be output first through the screen output unit 18. Also, the control unit 21 may output the phrase output from the screen output unit 18 through the voice output unit 19 by voice. Guidance texts and voices can be linked to recipe information and are stored in a matching state.

Thereafter, the user pours water into the cooking container 40 according to a phrase guided through the screen output unit 18 or the sound output unit 19. At this time, in the load cell 16, the weight is measured according to the amount of water contained in the cooking container 40, and the weight information measured by the load cell 16 is output through the screen output unit 18 by the control unit 21, The user can accurately follow 550 ml (550 g) of water while checking the weight displayed on the screen output unit 18. [

Meanwhile, if there is a variety of food ingredients required in the cooking process, if the screen output unit 18 guides the materials to be prepared in order, the user puts the respective materials on the plate 15, You can prepare. Of course, if the containers supporting the materials are different from each other, it is possible to carry out the weight initialization process first and then perform the weight measurement after putting the container containing the respective materials first.

In addition, when it is confirmed that a predetermined amount of material is prepared in the process of checking the weight of each material, the control unit 21 controls to output the announcement message " a predetermined amount of material is prepared " . If the weight of the material is insufficient or too large, the control unit 21 can inform the user of the excess or the shortage, and the user can add as much material as needed or remove the material from the overflowing material. Of course, depending on the user's eating habits, there may be a case in which a specific ingredient is placed more or less than a recipe more than the recipe. Therefore, the user can input an OK button for cooking using a specific material through the key input unit 12 In response to this, the control unit 21 stores the material information of the over-or-under state in the memory 22, and can refer to it later in the cooking process.

Of course, the control unit 21 reads the excess or defective material information stored in the memory 22 again in the cooking process using the same recipe, and then outputs the material information to the control unit 21 to guide the preparation of the specific material in accordance with the eating habits of the user It is possible.

When the weight of all the materials is checked, the control unit 21 heats the cooking vessel 40 placed on the base plate 15 according to the recipe information, and adjusts the thermal power based on the time set by the cooking step.

For example, in the case of ramen cooking, the control unit 21 outputs information such as 'boil water' on a screen or voice, and at the same time starts the operation of the heating means 17 to heat the water contained in the cooking vessel 40. Since the amount of water is determined in the recipe information, control information on how to boil the water for a few minutes with the firepower will also be stored in the recipe information. Accordingly, the control unit 21 controls the heating unit 17 to boil the water for a specific time with the specific heat power according to the recipe information.

If the user inputs the weight of the water in the recipe information in a random manner, or if the user inputs a lot of water, the control unit 21 may adjust the time for boiling water or the thermal power to match the amount of water . Of course, since the information on excess and defective materials deviating from the recipe is stored in the memory 22, the control of the thermal power control or the time control according to the excess or deficiency of the specific material in the cooking process can be flexibly controlled by the control unit 21.

If the water is boiling through the first heating process, then the control unit 21 can output an announcement message 'Please put a face', and if the user puts the face through the weight changed through the load cell 16 After confirming whether or not it is possible to carry out the following process. That is, counting is started from the point of time when the surface is inserted, and is heated for a proper time. Likewise, when the introduction of other materials is guided through each step and whether or not the material is input through the load cell 16, the cooking can be completed while reducing or increasing the thermal power.

3, the cooking apparatus 10 according to the present invention measures the weight of the material placed on the bed plate 15 and displays the weight of the material on the bed, By measuring and displaying the weight in real time in the cooking process, it is possible for the cooker to prepare a predetermined amount of ingredients in preparation for cooking and to check whether the cooking process is proceeding well with a predetermined amount of ingredients.

In addition, since the firepower control is automatically performed for a proper time according to the cooking progress process through the restaurant information received from the smart device 30, it is possible to prevent the cooker from failing to control the firepower.

Particularly, in the cooking apparatus 10 according to the present invention, since the balance and the heating means 17 are integrally formed in one main body 11, space utilization is high and the apparatus can be effectively used in a narrow kitchen.

Fig. 4 is a flowchart for explaining another example of the operation procedure of the cooking apparatus shown in Fig. 1. Fig. That is, the present invention relates to a specific situation that may occur during the automatic cooking process of the cooking appliance 10 described with reference to FIG. 3, so that the overflowing phenomenon during the cooking process can be quickly detected and the firepower control can be performed.

That is, during the process of heating the food contained in the cooking container 40 according to the process of FIG. 3, the contents may boil over. Therefore, the control unit 21 of the cooking apparatus 10 confirms in real time whether the contents are overflowing through the sound pressure sensor 13 and / or the vibration sensor 14 (S405).

When the food boils and overflows, the lid of the cooking utensil 40 vibrates with a rattle sound while rocking. Accordingly, the sound pattern and the vibration pattern information corresponding to the rolling sound are stored in the memory 22 in advance. When the sound pressure sensor 13 or the vibration sensor 14 detects sound and vibration, the control unit 21 It is determined whether sound and vibration are sound and vibration of a specific pattern stored in advance in the memory 22, and then it is determined whether or not the sound is overflowed. Of course, the control unit 21 may determine not to compare patterns of sound and vibration, but to overflow if sounds and vibrations of a predetermined size or more are recognized.

If it is confirmed that the food is boiling in the control unit 21, the control unit 21 controls the heating unit 17 to lower the thermal power to the lowest level so as to stop the overflow phenomenon. Then, To increase the firepower <S415>.

Of course, when the food is overcooked, the user can recognize the fact and control the firepower of the cooking utensil 10. However, if the user is left out, a considerable amount of food may already be overflowed to the cooking appliance 10, so that the cooking appliance 10 immediately recognizes the overflow phenomenon through the process of FIG. 4, It is possible to minimize the problems such as the failure to cook due to food overflow and the contamination of the support plate 15.

Fig. 5 is a flowchart for explaining another example of the operation process of the cooking appliance shown in Fig. 1. Fig. That is, the cooking apparatus 10 according to the embodiment of the present invention has a function of transmitting / receiving information to / from the smart device 30 via the local communication means 20, a function of automatically controlling the heating means 17, ) To analyze the sound of a specific pattern after recognizing the sound. These functions can be useful for parents who feed formula.

In other words, in the case of newborn babies, feeding should be done at short intervals regardless of nighttime. Breastfeeding is not a long process to prepare for breastfeeding, but breastfeeding requires boiling and boiling powdered milk, so the process of breastfeeding is quite long. Especially when you can not check the time to feed because you are at bedtime, you will not be able to make any preparations until the child bursts into a hungry crying at night. The cooking apparatus 10 according to the embodiment of the present invention can support such a problem to be minimized.

That is, the user (parent) can create a milking diary through the smart device 30. A breastfeeding log is a kind of record that records the amount of time and amount of breastfeeding given to newborn babies. In recent years, a milking log may be recorded through a dedicated application installed in the smart device 30.

Therefore, if the feeding log function is provided in a dedicated application that can be interlocked with the cooking appliance 10 according to the embodiment of the present invention and the user creates a feeding log in the dedicated application, the local communication means 20 of the cooking appliance 10 It is possible to perform short-range communication with the smart device 30 to periodically receive the lactation log information created in the smart device 30 and store the information in the memory 22 or share it in real time to set the control device 21 in the step S505. have.

Then, when the user puts the cooking container 40 prepared for the purpose of removing the powdered milk into the bed plate 15 and puts the water on the bed, the control unit 21 sets the feeding mode through the key input unit 12 Start working in feeding mode. The operation in the feeding mode means that the control unit 21 starts the operation of the heating means 17 after the control unit 21 determines the timing of the later feeding and promptly heats the milk powder contained in the cooking vessel 40.

There are various criteria for determining the feeding time point by the control unit 21 according to a predetermined setting, but in this embodiment, it is judged based on the baby's crying and the milking log.

That is, after the mode is set to the feeding mode, the control unit 21 analyzes the sound information recognized through the sound pressure sensor 13 and detects the sound of a specific pattern (pattern corresponding to the baby crying sound) stored in the memory 22 &Lt; S515 >

Newborns may cry when they are hungry, but they may cry for other reasons. Therefore, the heating means 17 should not be operated to feed the babies immediately because the baby's crying has been recognized. That is, when the baby's crying sound is recognized through the sound pressure sensor 13, the control unit 21 checks the milking log stored in the memory 22 or shared with the user's smart device 30 in real time, (S520). That is, it is judged whether 3 hours have elapsed from the existing feeding time. Depending on the newborn and the number of months, the feeding cycle is most common from 3 hours to 4 hours. Of course, the feeding cycle may be set by the user in advance, or the control unit 21 may analyze the feeding log stored in the memory 22, calculate the average feeding cycle of the baby, and set the reference feeding cycle.

The control unit 21 recognizes the baby's crying sound in the control unit 21 and operates the heating unit 17 to operate the milking unit 17 in step S525, Thereby rapidly heating the material. Therefore, it is possible to greatly reduce the time required for the user to check whether the feeding time has come, prepare time for reaching the kitchen to boil the water, and prepare for feeding the milk.

Of course, the control unit 21 is set in the feeding mode to judge whether the baby crying and the feeding time have come, and even if the heating means 17 is operated, the heating is stopped after a predetermined time.

In addition, since the infant is often fed during a period of time irrespective of the crying sound of the baby during the daytime, when the infant is set in the infant feeding mode, It is possible to start the heating only at the time of arrival of the baby, and to start the heating only at the time of the night when the crying of the baby and the arrival of the feeding time are all confirmed.

As described in detail above, the cooking apparatus 10 according to the present invention measures the weight of the material placed on the support plate 15 and displays the weight of the material on the screen. Thus, the weight of the materials required for cooking can be measured, By measuring the weight, it is possible for a beginner to prepare a certain amount of ingredients during cooking preparation, and to check whether the cooking process is proceeding well with a certain quantity of ingredients.

In addition, since the firepower control is automatically performed for a proper time according to the cooking progress process through the restaurant information received from the smart device 30, it is possible to prevent the cooker from failing to control the firepower.

Particularly, in the cooking apparatus 10 according to the present invention, since the balance and the heating means 17 are integrally formed in one main body 11, space utilization is high and the apparatus can be effectively used in a narrow kitchen.

In addition, if the contents are boiled over during the cooking process, recognize the overturning sound or vibration of the lid, check whether it is overflowed, and immediately lower the firepower to the lowest level and raise it step by step, .

In addition, when receiving the milking diary from the smart device 30 and storing it, and when the lactation mode is set, the heating means 17 is automatically activated when the lactation time has come or the baby's crying has been recognized, Can be saved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And additions should be considered as falling within the scope of the claims of the present invention.
