Description

Electric stove control method for maintaining the temperature of the contents {METHOD OF CONTROLLING HEATING AREA FOR MAINTAINING THE TEMPERATURE OF THE CONTENTS}

The present invention is a method for controlling a crater of an electric range for maintaining the temperature of the contents, and in more detail, firstly, the specific heat of the contents is estimated through the operation of the crater, and secondly, the user's desired temperature is maintained through the estimated specific heat. It relates to a cooking zone control method of an electric range that calculates the energy required for and supplies energy corresponding to the calculated energy from the crater.

An electric range is a cooking device that cooks food using an electric heater or a separate crater as a heat source, and an induction heater using an induction heating method according to the heating method and a radiant heater using an electric resistance method are provided. have.

As power is applied to the induction heater, a high-frequency voltage of a predetermined size is applied to the working coil to generate a magnetic field around the working coil, and the magnetic line of the induced magnetic field generated at this time generates an eddy current inside the crater. Then, the cooking zone is heated by this eddy current to cook.

Meanwhile, in the radiant heater, a predetermined power is applied to a heating coil inside the crater to emit high-temperature radiant heat due to self-heating of the heating coil, thereby cooking.

Such an electric range is usually equipped with a plurality of cooking areas, and is used in a hybrid form that allows the user to select an appropriate cooking area according to the type, quantity, and purpose of the food to be cooked by setting the output power of each cooking area differently. have. Unlike conventional gas ranges, electric ranges do not have the risk of explosion, are easy to use, do not generate soot due to incomplete combustion of gas, and are constructed by covering the top of the heating element with a flat top plate, so they have an aesthetic advantage. However, the number of users is increasing.

On the other hand, in recent years, interest in the technology of keeping the contents of a container placed on a crater for heating has been raised. Conventional techniques related to thermal insulation are generally configured in a manner in which the cooking zone heating time is controlled according to a user's set temperature. However, although there is a difference according to the physical properties of the contents, there is a problem in that the temperature of the contents of the container cannot be precisely controlled because the method is uniformly controlled only with time.

As a prior art, Korean Utility Model Registration No. 20-0178604 is disclosed. The prior art is a technology related to a pot that alerts the completion of cooking, and after the total heating time of a specific dish according to the amount of cooking is built in a timer in advance, when the user selects the amount of cooking, the timer operates and the set time elapses. It is a configuration that sounds an alarm. The prior art does not disclose an algorithm for keeping the contents warm, and simply depends only on the time set in the timer, so the temperature of the contents of the container cannot be precisely controlled, and the difference between the value selected by the user and the actual measured value is There is a problem with low reliability since it is highly likely to occur.

In addition, unlike the position shown in FIG. 1, the installation position of the faucet unit 120 may be changed according to the number, arrangement, and aesthetics of the crater H, and is not limited to the illustrated embodiment. Here, the water outlet control of the faucet unit 120 may be electronically controlled through the input unit 130 to be described later, but a valve is provided in the faucet unit 120 itself, and a mechanical control method is adopted to open and close by a user's manual operation. Can be.

'Crater (H)' is composed of a crater 1 (H1), a crater 2 (H2), and a crater 3 (H3) having different sizes and outputs. Accordingly, the user can select and use any one of a crater 1 (H1), a crater 2 (H2), and a crater 3 (H3) according to the size of the containers to be used or the output of the crater required by the user. A description of a method of heating the contents of the container P in the crater H of the electric range 100 will be omitted.

The'input unit 130' is touch-sensitive and performs a function of inputting a specific instruction signal by a user. The upper surface of the input unit 130 is formed of a touch screen panel, and the input unit 130 is modularized, so that only the input unit 130 can be replaced. The'input unit 130' is provided in a position convenient for the user to access among the upper surface of the main body 110 so as to facilitate the user's manipulation. In the input unit 130, a signal instructing the operation of the faucet unit 120 and the crater (H) is input from the user, and the start and end of the water outlet from the faucet unit 120, the amount of water out, the operation time and output intensity of the crater (H), etc. Various indication signals including a may be input. The input unit 130 includes a first region to an Nth region, and each region is configured to transmit a different indication signal to the control unit 170.

Description of control method of electric range

3 is a flowchart of a method for controlling a cooking zone for an electric range according to the present invention. 3, the present invention includes steps (S110) to (S150).

Step (S110) is a step in which the operation of the crater H is started after the initial temperature T0 of the contents in the container P located on the crater H is measured by the temperature sensor unit 101. As described above, the temperature sensor unit 101 can be regarded as the content temperature through the temperature measurement of the container (P). The initial content temperature (T0) is required in the process of calculating the energy supplied from the crater (H).

Step S120 is a step in which the crater H is operated by the control unit 170 so that the contents reach a preset first temperature T1. Here, it is preferable that the crater H is maintained and operated at a maximum output value in a preset range, and the first temperature T1 is the boiling point of the contents. Here, the first temperature (T1) is set as the boiling point of the contents, when the temperature of the contents reaches the boiling point, there is no temperature change for a predetermined time. Using this principle, the control unit 170 easily determines the boiling point. Because you can. The temperature sensor unit 101 senses the temperature of the contents in real time, and the temperature information of the sensed contents is transmitted to the control unit 170 in real time. When the temperature of the contents does not rise for a predetermined time set in advance, the control unit 170 determines that the temperature of the contents has reached a boiling point. In order to reach the boiling point quickly, the crater (H) is preferably operated at its maximum output. However, when the crater H is operated at the maximum output depending on the type of contents, the condition of the contents may be damaged, so it is preferable to configure the output level to be adjusted according to the user's setting.

The output value of the crater H is configured to be selectable from a first output mode to an Nth output mode, wherein the first output mode is the minimum output, and the Nth output mode is the maximum output. It is preferable that the output temperature of the crater H is set to gradually increase as the first output mode goes to the Nth output mode. Here, in the first to Nth output modes, the operating time of the crater H is preset for each of the crater H, and the crater H is controlled through the output temperature and the operating time of the crater H. Here, the output value means the output energy per unit time. The output mode of the crater H can be adjusted not only by the output energy per unit time (in proportion to the temperature of the crater H), but also by setting the operating time of the crater H. This is because when the operating time increases, the output energy of the crater H also increases.

On the other hand, when the content does not reach the first temperature T1 within a preset time, the first temperature T1 is reset to a third temperature T3 close to the current temperature of the content, and the first energy E1 ) May be calculated through the time required until reaching the third temperature T3. The preset time refers to the maximum heating time of the crater (H), and it is undesirable in terms of energy consumption that the crater (H) is operated indefinitely to reach the first temperature (T1). , I set the time limit.

In step S130, the required time until the content reaches the first temperature T1 is calculated and transmitted to the control unit 170, and the control unit 170 uses the required time to This is the step in which 1 energy (E1) is calculated. Here, the first energy E1 is preferably calculated through the product of the output value per unit time of the crater H and the required time.

Step (S140) is a step in which the second energy (E2) required to maintain the content temperature at a preset second temperature (T2) by the control unit 170 is calculated, the first energy calculated in step (S130) This is a step in which the second energy E2 is calculated through (E1) and a predetermined equation. More specifically, a predetermined formula may be calculated using Q=CㅇMㅇΔT as an example (C is a specific heat, M is a mass, and ΔT is a temperature change). It is usefully used when the contents contain other cooking materials other than the water discharged from the faucet part 120. For example, when the stew is kept warm, it is cumbersome to separately obtain the specific heat since the stew is in a state in which other cooking ingredients are mixed in addition to water.

In this case, the energy supplied from the crater (H) is calculated through the product of the output value per unit time of the crater (H) and the required time, as described above, and ΔT is the first temperature (T1) minus the initial temperature (T0). If one value is applied, the product of C (specific heat) and M (mass) can be calculated at once. The second energy E2 required by the product of the calculated C (specific heat) and M (mass) and the second temperature T2 set by the user may be calculated.

In this process, the first energy (E1) is calculated by further considering the loss energy lost to the container (P) or air among the energy supplied from the crater (H), and the output value per unit time of the crater (H) and the required time A value obtained by subtracting the loss energy from the product of may be determined as the first energy E1. It is practically difficult to transfer all of the energy supplied from the crater H to the contents of the container P without loss. For a more accurate calculation of the second energy E2, it is desirable to further consider this loss energy. In addition, it is preferable to consider the thermal energy of the contents when the boiling point is reached when calculating the second energy (E2). Meanwhile, the second temperature T2 can be selected by the user, and the user generally uses the content to be maintained at a specific temperature below the boiling point rather than maintaining a boiling state.

Step (S150) is a step in which the second energy (E2) is supplied from the crater (H) to the contents in the container (P), and the output of the crater (H) is controlled by the control unit 170 to control the contents in the container (P). This is a step in which the temperature is maintained at the second temperature T2. As will be described later, the crater H may be operated intermittently or continuously in order to supply the second energy E2 to the contents.

Specifically, the control unit 170 may be configured to receive temperature information of the contents in the container P provided in real time from the temperature sensor unit 101 and intermittently operate the crater H at a preset time interval. .

4, a temperature change according to the first embodiment of intermittently operating the crater H is shown. In FIG. 4, when the control unit 170 receives temperature information of the contents in the container P provided in real time from the temperature sensor unit 101, and the temperature information of the contents is less than the second temperature T2, the crater H Is shown to operate. More precisely, when the temperature falls below the second temperature (T2), the crater (H) is not operated immediately, but is configured to operate when the crater (H) falls below the predetermined temperature set in advance than the second temperature (T2). It is desirable to be. Assuming that the crater (H) is intermittently operated, when the second temperature is set to the reference temperature for the crater (H) operation, the crater (H) operation is turned on and off too frequently, thereby reducing power consumption. It is for sake.

It is preferable to turn off the operation of the crater H based on the case where the temperature of the contents reaches the second temperature T2. This is because even if the operation of the crater H is turned off, the contents are heated by residual heat. As a modification of the operation of the crater H, when the temperature information of the contents exceeds the second temperature T2 by a preset value, the operation of the crater H may be stopped.

Referring to FIG. 5, a temperature change according to the second embodiment of continuously operating the crater H is shown. Also in FIG. 5, the control unit 170 is configured to receive temperature information of the contents of the container P provided in real time from the temperature sensor unit 101. Here, the control unit 170 is configured to supply only energy necessary to keep the temperature of the contents constant at the second temperature T2, and this energy supply is continuously provided by the crater H. The second energy E2 supplied here is determined while calculating the first energy E1, as described above.

Meanwhile, in the electric range provided with the faucet part 120, water as much as a user's desired capacity may be discharged through the input part 130. When the user inputs the amount of water in the input unit 130, information about the amount of water in water is transmitted from the input unit 130 to the control unit 170, and the first energy (E1) and the second energy (E2) can be easily calculated using the water amount information. have. After heating only water in the empty container P, it can be very usefully used when the user desires to keep the water at a specific temperature (heat insulation).

Even in this case, a predetermined formula of Q=CㅇMㅇΔT can be applied. Since the specific heat of water is a known constant value, a process of obtaining M (mass) is required. In order to obtain M (mass), it is possible to use information on the amount of water outlet measured through a flow sensor built into the faucet part 120. This is because the density of water is also a known constant value. In addition, the mass of water in the container (P) can be determined through the mass change of the container (P) before and after water outlet from the faucet part 120 using a mass sensing sensor (not shown) provided on the side of the crater (H). have.

In the above, the present specification has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention, but this is only exemplary, and those skilled in the art can use various modifications and equivalents from the embodiments of the present invention. It will be appreciated that embodiments are possible. Therefore, the scope of protection of the present invention should be determined by the claims.
