Abstract

PURPOSE: To easily bake a full-scale cake as well as cook rice by an electric rice cooker. CONSTITUTION: The rice cooker comprises a pot 2 stored inside a body for storing a heated material, a bottom heating means 4 for heating the pot, a pot sensor 7 for detecting the temperature of the pot and controlling the bottom heating means, a lid heating means 5 mounted inside the lid, an operation part 6 mounted on the body with a button at least for starting a rice cooking course and a cake baking course, and a control means for driving/controlling the bottom heating means and the lid heating means. In the rice cooker, a first set temperature is predetermined in the cake baking course, and a second set temperature is predetermined to be increased by the remaining heat after the heating by the bottom heating means is temporarily suspended when the temperature of the heated material reaches the first set temperature. As a result, rice can be cooked and a cake can be baked as well in the body 1 with the operation of one button. In addition, the overshoot of the temperature rise of the bottom of the pot is inhibited, and therefore, the cake can be easily baked and excessive burning or drying of the lower layer of the cake can be prevented.

Description

Cooker {COOKER}

The present invention relates to a cooker capable of baking a cake.

A cooker is cooked only, and it is common until recently to use an oven when baking a cake.

On the other hand, however, especially in families with children, there are many opportunities for mothers to make cakes as a means of promoting communication between parents and children. In this case, when cooking food as mentioned above, a cooking machine is used, and when baking a cake, an oven is used. That's why preparation and time are needed.

The cooking apparatus of the present invention has a pot for receiving the heated object, a bottom heating unit for heating the heated object through the pot, and a pot sensor for detecting the temperature of the heated object accommodated in the pot. And a control unit for incorporating at least the white rice course and the cake course, and a control unit for driving the bottom heating unit by incorporating the white rice course and the cake course. In the cake course, the first set temperature and the second set temperature are set in advance. Then, when the temperature detected by the pot sensor reaches the first set temperature, the heating by the bottom heating unit is temporarily stopped, and the temperature is increased by excess heat until the second set temperature is reached.

Fig. 1 is a characteristic diagram of the "cake course 1" of the cooking machine in the first embodiment of the present invention, in which the temperature and the change of the detection temperature of the pot sensor 7 and the lid sensor 8 which are temperature sensing elements are shown. The relationship of the heating control according to this is shown. 2 is a cross-sectional view of the rice cooker in the present embodiment. 3 is a block diagram related to heating control of a cooker.

The cooking appliance according to the present embodiment includes a main body 1, a pot 2 which accommodates the heated object and a cover 3 that covers the opening of the upper surface of the main body 1 and the pot 2 by receiving the heated object. Have The bottom heating part 4 which contacts the outer bottom part of the pot 2 and heats the heated object through the pot 2, and the lid heating part 5 which is installed in the lid 3 to heat the heated object 5 Has Moreover, it has the operation part 6, the pot sensor 7, and the cover sensor 8. The operation part 6 is provided in the main body 1, and operates at least a white rice course and a cake course. Specifically, it is an operation button. The pot sensor 7 contacts the center of the outer bottom of the pot 2, and detects the temperature of the heated object through the pot 2. The lid sensor 8 is installed in the lid 3 and detects the temperature in the pot 2. The timer 9 measures the time of each process. The control part 10 is based on the input from the pot sensor 7, the cover sensor 8, the timer 9, and the operation part 6, The bottom heating part 4, the cover heating part 5, and the notification part ( 11) drive control. The control unit 10 incorporates a white rice course and a cake course. The notification unit 11 notifies that all are baked, and this is made of a buzzer or the like.

In the cooking apparatus comprised as mentioned above, the operation | movement and operation | movement at the time of cooking by the cake course of FIG. 1 are demonstrated. First, the cake batter is accommodated in the pot 2, and is installed as shown in FIG. Then, when the cake course is selected and input from the operation unit 6 and the cooking switch is turned on, cooking starts.

Following the cooking start, the heating process is carried out after a waiting process for waiting for an arbitrary time. In the heating step, the control unit 10 controls the bottom heating unit 4 and the lid heating unit from the heating start of the pot 2 until the detection temperature of the pot sensor 7 reaches the preset first set temperature T1. 5) Power on.

Next, a thermal heating process is performed. In the excess heat heating process, the control part 10 stops heating of the pot 2 by the bottom heating part 4, and raises the temperature of the cake batter by the extra heat. In the heating step described above, the heating temperature in the above-described heating step is a second set temperature (the pot sensor 7 is higher than the temperature and suitable for baking the cake after the detection temperature of the pot sensor 7 reaches the first set temperature T1). It continues until it detects T2). Here, T1 is set to 115 ° C and T2 to 125 ° C. In addition, the lid heating part 5 also supplements the heating of the pot 2 during this thermal heating process.

Next, a baking process is performed. In the baking process, the bottom heating part 4 and the lid heating part 5 heat the pot 2 in the predetermined optimal process time. Here, the process time is set to 40 minutes. Then, the timer 9 measures the time, and after the predetermined 40 minutes have elapsed, the control unit 10 terminates the energization of the bottom heating unit 4 and the lid heating unit 5, and at the same time, the notification unit 11 runs out. Inform that it is baked.

As described above, the heating cooking method of the present embodiment includes a heating step, a thermal heating step and a baking step. In the heating step, the heated object in the pot is heated at a constant output until the first set temperature T1 set in the bottom heating unit 4 is reached. In the excess heat heating step, the heating by the bottom heating unit 4 is temporarily stopped until the second set temperature T2 set in advance in the bottom heating unit 4 is reached from the first set temperature T1, and the heating target object is heated. The water is heated by heat. Thereby, the temperature rise of a pot bottom suppresses excess overshoot, and also bakes a cake easily, and also prevents the cake lower layer from being excessively baked. In addition, the bottom heating part 4 and the lid heating part 5 are heated from above and below to realize more authentic cake baking. In addition, in this embodiment, although T1 = 115 degreeC and T2 = 125 degreeC was set, T2 is the temperature which rises from T1 to the excess heat, and can be changed suitably by the heating setting of the bottom heating part 4. In addition, T1 is not limited to the said numerical value, It can change according to the material of a cake batter.

On the other hand, in the lid heating part 5, the heating time M1 which is a time suitable for supplementing the heating to a cake surface layer is set. The control unit 10 energizes the lid heating unit 5 based on the heating time M1 to heat the heated object. Here, heating time M1 is set to 20 minutes. The baking time is set in advance in the same manner as in the first embodiment, and 40 minutes is set here. Then, the timer 9 measures the time, and after the predetermined 40 minutes have passed, the energization of the bottom heating unit 4 and the lid heating unit 5 is finished, and the notification unit 11 is burned out.
