The present invention relates to the cooking time display of the electric pressure cooker, in particular, to determine the serving capacity of the rice to be cooked to determine the required time of the cooking process, to display the remaining time counted down and the remaining time when displaying the steaming process time The present invention relates to a cooking time remaining display device and a method of an electric pressure thermal cooker that accurately displays the estimated time of completion of the cooking process as the remaining time.

As civilization develops, people develop and develop various kinds of tools for daily life more conveniently. For example, there are numerous devices such as automobiles, televisions, washing machines, refrigerators, air conditioners, computers, telephones, and the like as an auxiliary means for enriching and convenience of modern life. In the case of cars, it is convenient to carry out walking, the television can check the scenery and news from afar, the washing machine helps to wash clothes, the refrigerator to keep food from being damaged, and the air conditioner Computers save you the trouble of thinking, and phones deliver urgent news quickly.

Electric rice cookers or rice cookers (hereinafter referred to as electric rice cookers) are very useful in modern life, especially in housewives, where time is very short. Such an electric rice cooker is largely divided into a cooking process for cooking rice to be cooked rice, and a thermal insulation process for preserving rice built by the cooking process in a state of a constant temperature.

According to the prior art with reference to Figure 1, when describing the control device of the rice cooker, the heating unit 10, the control unit 20, the display unit 30, the key button unit 40, the temperature sensing unit 50 It is configured to include.

The key button unit 40 is provided with a plurality of key buttons on the outer surface of the rice cooker and selects and inputs various operation modes such as cooking and reheating, cooking menu selection and cancellation, and commands input from the key button unit 40. The signal is input to the control unit 20. The control unit 20 displays the state of the input command signal and the operating state of the electric rice cooker on the display unit 30, and controls and monitors the heating unit and the temperature sensing unit to cook the electric rice cooker process mode, moxibustion process mode, thermal insulation process mode Operate with

For example, the control unit 20 confirms the command signal input of the cooking from the key button unit 40 starts the heating by controlling the heating unit 10, the predetermined temperature of the bottom temperature sensor and the lid mounted on the bottom of the rice cooker of the rice cooker Monitor the temperature sensing unit 50 consisting of the upper temperature sensor mounted in place to measure and confirm the internal temperature of the rice cooker. The display unit 30 displays the operating state and the measured temperature under the control of the controller.

Referring to the general cooking process of the electric rice cooker with reference to Figures 2 and 1 are largely divided into a steaming process of heating the rice cooked by heating and steaming the rice cooked in the cooking process.

The ripening step can be subdivided into a soaking step (T1), a heating step (T2), and a boiling step (T3). When the command signal for selecting the cooking mode is input from the key button unit 40, the control unit 20 controls the heating unit 10 to increase the internal temperature of the rice cooker so that water is absorbed into the rice inside the inner pot. Step T1 is performed for a predetermined time. In other words, before the temperature of the inner pot is rapidly increased, the rice is absorbed with sufficient moisture to obtain an optimal gelatinization state.

Here, the luxury state refers to a phenomenon in which MICELLE collapses in order from the outside. In general, starch is composed of a dense bundle of starch molecules in close contact with each other, which cannot enter water molecules, which is called micelles. When water is supplied to these starch molecules and heated, the micellar structure melts and the molecules widen between molecules, creating a gap, which is called swelling. This swelling is a phenomenon in which the viscosity of the rice increases and the whole becomes a translucent uniform colloidal material.

When the soaking step (t1) is completed, a heating step (t2) is performed to rapidly increase the temperature inside the rice cooker to heat the rice sufficiently absorbing moisture, and then the inner temperature of the rice cooker is cooked by heating the inner pot. A boiling process t3 is performed to rise up to.

After the completion of the cooking process, the cooking process of the gelatinization process in which the rice is rice is finished by performing a steaming process (t4) of heating the cooked rice to a predetermined temperature for a predetermined time, and the rice cooker is kept warm by the warming process. The mode is switched.

In one example, the cooking process of the cooking process is terminated when the temperature value detected by the temperature sensor 50 by the temperature sensor mounted on the bottom of the rice cooker reaches the temperature value previously input to the control unit 20. In addition, the time required for the start and end of the cooking process is different depending on the amount of rice input for cooking.

The controller 20 controls the heating unit to heat the cooker, and then monitors the temperature sensing unit 50 to count the time until the cooker reaches a predetermined temperature and counts the serving capacity of the rice put into the cooker. Or can be determined. However, this conventional technology can check or determine the serving capacity of the rice put in after a certain time has passed by the cooking process, so it is necessary to wait a lot of time to determine and display the time required for cooking, cooking in an electric rice cooker The required time or cooking end time could not be displayed.

This prior art has a problem that it is not possible to adjust the time to prepare the side dishes because the time required to complete the cooking or the completion time of cooking until the rice is finished after the rice is started at the start of cooking.

In addition, when the serving capacity of the rice put by the electric pressure thermal cooker user is not expected at the beginning of the time required for the cooking process, there is a problem to wait while monitoring and attention until the completion of cooking.

The present invention displays the expected completion time for cooking at the beginning of the rice in the rice cooker and start cooking, in particular, the expected cooking capacity of the rice put into the rice cooker in the middle serving and displays the normal remaining time in the moxibustion process It is an object of the present invention to provide an apparatus and method for controlling the cooking time remaining of an electric pressure thermal rice cooker to be displayed.

In addition, the present invention can anticipate the completion time of cooking in the state of cooking with an electric pressure cooker, providing a sense of mental stability to prepare a side dish and other foods to increase the user's preference and mass production possible It is an object of the present invention to provide a device and a method for controlling the remaining time of cooking rice cooker.

Hereinafter, according to the present invention having the configuration as described above, it will be described in detail with reference to the accompanying drawings, the display device and the method of cooking remaining time of the electric pressure thermal cooker.

In order to explain the present invention, Figure 3 is a functional block diagram of the cooking time remaining display device of the electric pressure thermal cooker according to an embodiment of the present invention, Figure 4 is a cooking residue of the electric pressure thermal cooker according to an embodiment of the present invention Figure 5 is a time display method flow chart, Figure 5 is a flow chart of the operation method of the moxibustion process of the electric pressure thermostat rice cooker according to an embodiment of the present invention, Figure 6 is a diagram illustrating a pressure cooker control algorithm according to an embodiment of the present invention, Figure 7 is the present invention Is a state diagram of a table recorded in a table section according to an example.

In describing an example of the present invention, description is omitted for well-known technical contents that are not directly related to the present invention, and thus clearly conveys the gist of the present invention without obscuring the gist of the present invention.

Referring to FIG. 3, when the cooking time display device of the electric pressure thermal cooker according to an embodiment of the present invention is described, a heating unit 100 generates heat to heat the rice cooker; A temperature sensing unit 110 for detecting an internal temperature of the rice cooker; Table unit 120 for recording the cooking process time and the steaming process time for each cooking capacity to a table; A control unit 130 for performing cooking with the cooking time of the middle serving and controlling and monitoring to display the corrected remaining time by searching; Counting unit 140 for counting the total time required for the cooking process and the moxibustion process and cooking; A display unit 150 displaying remaining time of the cooking process and the moxibustion process; A key button unit 160 for inputting a control command of the cooking process and the warming process; This configuration is included.

According to the present invention having the above configuration, when the cooking time display device of the electric pressure thermal cooker is described, the controller 130 monitors the key button unit 160 and confirms that a command signal for cooking is mounted on the rice cooker. Since the heating unit 100 is heated to control the inside of the cooker to generate a predetermined temperature.

Although there are differences depending on the model and design of the electric pressure thermal rice cooker, in general, the heating unit 100 is provided at the lower part and the side and the lid of the rice cooker, respectively.

The control unit 130 monitors the temperature detecting unit 110 to detect the internal temperature of the rice cooker, and receives and analyzes the time information after the start of cooking from the counter 140 to determine the serving capacity of the rice put into the rice cooker. do. This determination takes advantage of the fact that the time for reaching the predetermined temperature set by the serving capacity of the rice put into the rice cooker is different. That is, when the serving capacity of the rice is small, the time to reach a predetermined temperature is short, and when the rice serving capacity is large, the time is long. Referring to FIG. 7, the time for reaching a predetermined temperature of two servings of rice is within about three minutes, within four minutes for four servings, within seven minutes for six servings, and for eight servings. Dosage takes less than 9 minutes and 10 servings takes more than 10 minutes.

As such, when confirming the quoted capacity of the rice put into the rice cooker, it is possible to check the total time required for the cooking process. The cooking process is divided into a cooking process that continuously heats rice in a ready-to-eat state and a moxibustion process that contains proper moisture. This time is confirmed by repeated experiments. In general, there is little difference depending on the water content of the rice. Rice gradually loses its moisture content after harvesting by harvest. In addition, the rice becomes more viscous or sticky if it absorbs enough moisture before ripening.

Referring to the attached FIG. 6, the control algorithm of the electric pressure thermal cooker according to the present invention will be described. The controller 130 repeats the experiment when a command signal for proceeding the cooking process is input from the key button unit 160. And secured by the effort, the soaking process of heating the cooker by controlling the heating to the main heater, the top heater, the side heater constituting the heat generating unit 100 for the time of T1 until the inside of the cooker is detected as T1 temperature Proceed.

At this time, since the controller 130 cannot check the serving capacity of the rice put into the rice cooker, the time corresponding to the middle serving is set, the counter is controlled to proceed with the down count, and the remaining counted down time is displayed on the display unit 150. Provided and displayed.

The controller 130 monitors the temperature sensing unit 110 to detect the T1 temperature, and monitors the counter 140 to take the time of T1, so when it is confirmed that the soaking process is completed, the temperature of T2 is reached. The primary heating process is processed for a time, and when the primary heating is completed, the secondary heating process is performed for a time of T3 to reach the temperature of T3. When the secondary heating is complete, the boiling process is performed for the time of T4 to reach the temperature of T4 again. The whole process is called a ripening process, and the control unit 130 controls the main heater, the top heater, and the side heater constituting the heat generating unit 100 in a heated state.

Since the control unit 130 is in a state in which the serving capacity of the input rice cannot be confirmed at the initial stage when the cooking command signal is input, the control unit 130 sets the time required for the cooking process of the intermediate serving and controls the counter 140 to count down. At the same time, since the remaining time counted down is checked and provided to the display unit 150, the remaining time of the cooking process is displayed. In addition, while the cooking process is processed, the controller 130 monitors the temperature sensing unit 110 and the counter 140 to determine how much time has elapsed as the cooking temperature and cooking time of the cooker are started. That is, when the internal temperature of the rice cooker reaches a predetermined temperature, the cooking time is checked and the table 120 is searched for the identified time, so that the serving capacity of the rice put into the rice cooker is determined.

When the serving capacity of the rice put into the rice cooker is determined, the time required for the cooking process is checked by searching the table unit 120, and it is set initially, and is compared with the cooking process time corresponding to the intermediate serving. That is, it is checked whether the time of the found ripening process is small or large in comparison with the ripening process time searched by the serving amount of the injected rice and the ripening process time of the middle serving initially set.

If the time of the ripening process found in this confirmation is long, that is, more time is needed, the control unit 130 counts down by the counting unit 140 and provides a down count of the remaining time provided and displayed on the display unit 150. The display unit 150 stops and displays the stopped remaining time on the display unit 150. In addition, the control unit 130 is determined by monitoring the counting unit 140, the cooking process time required for serving capacity and the internal temperature of the cooker confirmed by monitoring the temperature sensing unit 110 reaches a predetermined temperature. In this case, the display of the ripening process time to be displayed in the stopped state is erased, the corresponding steaming process time is displayed, and the counter is controlled and down counted. The moxibustion time down counted as described above is based on the determined serving capacity, so the correct remaining time is displayed.

The moxibustion process is a state in which the cooked rice is not fully inflated yet, so lower the internal temperature of the rice cooker and let the rice absorb enough water so that the rice expands completely so that it is a good rice to eat smoothly. The cooker is heated by the heater. The controller 130 maintains the moxibustion 1 process for T5 hours, maintains the moxibustion 2 process for T6 hours, and then operates the solenoid valve to discharge the internal steam of the pressure cooker. The process of step 3 is processed, and when the moxibustion 3 process is completed, the moxibustion process is completed and the cooking process is completed, and the thermal insulation process is performed. When the moxibustion process is completed, the display unit 150 indicates the completion of the moxibustion process and operates a routine of the heat insulation process.

That is, the present invention displays cooking time by middle serving when cooking starts, displays remaining time by down count, corrects when the moxibustion process is started, and corrects the remaining time by moxibustion process. This has the advantage of predicting completion time.

Referring to Figure 4, when the method of displaying the remaining cooking time of the electric pressure thermostat rice cooker according to an embodiment of the present invention, the process of heating and operating in the cooking process of the middle serving when cooking; Displaying the remaining time of the cooking process, determining the cooking capacity, and setting the moxibustion process time; Correcting the remaining time with the retrieved cooking process time and confirming the end of the cooking process; Operating the moxibustion routine and the warming routine; This is the configuration that is included.

The moxibustion routine may include: checking the moxibustion process time and controlling the invention; Displaying the time to be counted down; Displaying cooking completion at the end of the moxibustion process; Included configuration.

With reference to the accompanying Figures 4 and 5 below, with reference to the drawings described above, according to an example of the present invention, it will be described in detail the method of displaying the cooking time of the electric pressure thermal cooker.

If it is confirmed by the control unit 130 to analyze the command signal input from the key button unit 160 to collect (S100), regardless of the serving capacity of the rice put into the rice cooker set the cooking process time by the middle serving ( S110), so that the heating unit 100 consisting of the main heater and the top heater and the side heater generates heat to operate the rice cooker (S120).

Since the control unit 130 controls the counting unit 140, the counting process time is down counted to a middle serving rice capacity, and the down counting time is displayed as the remaining time to be completed until the ripening process is completed. And display the result (S130).

The control unit 130 monitors the temperature detecting unit 110 to detect the internal temperature of the rice cooker, and monitors the counter 140 to detect the time required from the start of cooking to the present, and thus detected information To determine the serving capacity of the rice put into the rice cooker (S140). At this time, the controller 130 analyzes the time required for the cooker to reach a predetermined temperature, thereby determining the serving capacity of the injected rice. The data is secured by repeated experiments and efforts, and the table unit 120 is used as a table. Recorded and maintained.

When determining the serving capacity of the rice put into the rice cooker, the controller 130 retrieves the time required for the cooking process of the determined cooking capacity and the time required for the moxibustion process from the table 120 (S150), respectively. The moxibustion process time searched by the serving capacity determined as described above is set to the moxibustion process time of the cooking process in progress (S160).

In addition, it is checked whether the larger value is compared with the ripening process time (hereinafter retrieval time) retrieved by the determined serving capacity of the rice and the ripening process time (set time) set as an intermediate serving as initially set (S170). .

When the search time is determined by the controller 130 to be greater than the set time, the counting unit 140 is controlled to stop the down count of the set time and display the current remaining time value at which the down count is stopped in a fixed state. 150) (S180). The remaining time value output in the fixed state as described above is continued until the end of the cooking process (S200).

In addition, when the setting time is confirmed by the control unit 130 to be greater than the search time, the counting unit 140 is controlled to continue the down counting of the set time, and the remaining counting time is provided to the display unit 150 for display. And (S190), such a display method continues until the end of the cooking process (S200).

Therefore, in the present invention, the cooking time by the middle serving is displayed from the beginning of cooking and the remaining time by the down count is displayed, and thus the cooking time can be expected.

The control unit 130 confirms that the cooking process is completed, and operates the routine of the moxibustion process (S210). 5, the moxibustion process routine will be described in detail with reference to FIG. 5. The moxibustion time set by the controller 130 is checked (S300), and the heat generation by the moxibustion process is controlled and operated (S310).

The controller 130 controls the counter 140 to provide the display unit 150 with the remaining counted down time of the set moxibustion process time (S320). When it is confirmed by the controller 130 that the moxibustion process is completed (S330), the display unit 150 is controlled to display the completion of cooking (S340).

Moxibustion process time is different depending on the cooking capacity of the rice put into the rice cooker, as shown in the attached Figure 7 as an example, it takes about 9 minutes for two servings, about 12 minutes for 6 servings. In the case of a 10 serving dose, it takes about 15 minutes and these results are obtained by repeated experiments and efforts.

If it is confirmed by the control unit 130 that the moxibustion process routine is completed, the heat insulation process routine is operated and proceeds to the end (S220).

Therefore, when the rice is put into the electric pressure thermal rice cooker and starts cooking, the present invention having the above configuration displays the remaining time by the middle serving, corrects and displays the cooking capacity in the checked state, and finally in the moxibustion process. Since the display is accurate, there is an advantage of predicting the time required for cooking overall.

Although the present invention has been described as an example, it is not necessarily limited to such an example, and various modifications can be made without departing from the spirit of the present invention. Therefore, one example disclosed in the present invention is not intended to limit the technical spirit of the present invention but to explain, and the scope of the technical spirit of the present invention is not limited by the one example.
