Is carried out, and moreover to rotate the blade between them since the heat while interchanging the bottom side of the glutinous rice and the upper glutinous rice in the cooking casing, it is possible to uniformly moderately water-heating in a short time. In addition, since the rotation speed or rotation speed of the blades during the rice cooking process can be changed according to the state and amount of glutinous rice being heated, the rotation speed of the blades is too high and the blades are scattered in the cooking case. It is too late and the whole is not stirred, or the number of rotations in the state where the glutinous rice has progressed to paste becomes sticky, or the glutinous rice that is in contact with the cooking case becomes too scorched. In addition, it is possible to make a stable and consistent texture regardless of room temperature fluctuations, voltage fluctuations, and material variations, and is easy to use.

  The fourth invention determines the cooking time of the rice cooking process and / or the sticking process according to the temperature immediately after the start of cooking of any one of the first to third inventions, because the room temperature is low or When the temperature rise in the cooking case is slow due to the amount of cooked rice, a sufficient amount of heat can be obtained for the glutinous rice to be gelatinized by setting the rice cooking process time longer. Also, if the room temperature is low even during the sticking process, the lid is opened during the sticking process, and the temperature in the cooking chamber suddenly drops, so the blades are loaded. can do. Further, by determining the cooking time based on the temperature immediately after the start of cooking, the amount of heat for cooking the glutinous rice can be obtained without excess or deficiency, and the cooking time is set according to the state of the glutinous rice.

  In particular, the fifth aspect of the present invention is to hold the cooking room when the time has elapsed without the operation of shifting to the process to be performed by the user after completion of the rice cooking process of any one of the first to fourth aspects of the invention. Therefore, the temperature is kept at an optimum temperature for a certain period of time, whereby the inside of the cooking case can be maintained at the optimum temperature for sticky rice.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
The cooking device in the 1st Embodiment of this invention is demonstrated using FIGS. FIG. 1 is a cross-sectional view showing a schematic configuration of a cooking device in the present embodiment.

  In FIG. 1, 1 is a blade, 2 is a cooking case in which the blade 1 is detachably attached to the bottom, and a material such as glutinous rice or water, 3 is a driving means for rotating the blade 1, A cooking chamber for cooking rice cake, 5 is a heating means that serves as a heat source during the rice cooking process, 6 is a control for controlling the driving means 3, the heating means 5, and a temperature detection means 9 for detecting the temperature of the cooking chamber 4. Means, 7 is an input means for selecting a cooking course, 8 is a display means for displaying the cooking course, and 10 is for sealing the cooking chamber 4 during use and for putting the cooking case 2 in and out before and after use. It is a lid.

  About the cooking appliance comprised as mentioned above, the operation | movement / effect | action is demonstrated below.

  First, wash the glutinous rice and water according to the amount of the glutinous rice into a cooking case 2 fitted with blades 1, attach it to the main body 15, close the cooking chamber 4 with the lid 10, and use the input means 7 Select to start the operation. Hereinafter, the cooking device operates according to the process diagram of FIG.

  First, it consists of two processes, a rice cooking process and a sticking process, and reaches the first predetermined temperature θ1 while energizing the driving means 3 and rotating the blade 1 during the temperature rise (t0 → t1) in the initial stage of the rice cooking process. Until the heating means 5 is energized.

  As described above, by stirring the blade 1 during the rice cooking process, the lower glutinous rice on the cooking case 2 and the upper glutinous rice are heated while being exchanged.・ Can be heated.

  Moreover, the stirring during the rice cooking step causes the blade 1 to move intermittently at a rotation of about 0.5 to 2.0 seconds every 10 seconds to 1 minute depending on the elapsed time and the temperature in the cooking chamber 4. Furthermore, when the pasting of the glutinous rice in the cooking case 2 is almost finished, the entire glutinous rice during cooking is reliably stirred uniformly by rotating the blade 1 for about 20 seconds. At this time, sufficient moisture and heat can be obtained for pasting the glutinous rice that has not been obtained with sufficient moisture and heat by uneven heating in the rice cooking process so far. As described above, the drive means 3 is controlled by the control means 6 so that the glutinous rice in contact with the cooking case 2 is not burnt at a rotation speed at which the grains of glutinous rice are not crushed. Since the blades 1 are stirred in an appropriate and uniform manner, moisture can be made uniformly.

  In the present embodiment, during the rice cooking process, the heating means 5 is energized while gently rotating the blade 1 every few seconds until the temperature of the cooking chamber 4 reaches the first predetermined temperature θ1. The temperature rise is continued, and immediately after the inside of the cooking chamber 4 reaches the first predetermined temperature θ1, the energization rate to the heating means 5 is immediately reduced to a second predetermined temperature θ2 lower than the first predetermined temperature θ1. To hold for a predetermined time (t1 → t2). Further, after holding the temperature at the second predetermined temperature θ2 for a predetermined time (t1 → t2), in the attaching step, the blade 1 is stirred up by increasing the power supply rate to the driving means 3.

  Next, a control example when the temperature at the start of cooking is low will be described with reference to the process diagram of FIG.

  In this control example, when the temperature at the start of cooking is θ0 ′ lower than θ0 by a certain temperature, the heating means 5 is energized until it reaches the first predetermined temperature θ1 ′ from θ0 ′ in the rice cooking process, and the cooking chamber The temperature rise continues until the temperature of 4 reaches the first predetermined temperature θ1 ′, and immediately after the cooking chamber 4 reaches the first predetermined temperature θ1 ′, the heating means 5 is energized immediately. The temperature is held for a predetermined time at a second predetermined temperature θ2 ′ lower than the first predetermined temperature θ1 ′ at a reduced rate.

  At this time, θ2 ′ is a temperature lower than θ2 in the process chart shown in FIG. 2, and θ1 ′ is a temperature lower than θ1 in the process chart shown in FIG. In addition, the time (t1 → t2) to be held at the second predetermined temperature θ2 ′ and the time for the attaching process (t2 → t3) are determined by the temperature of the cooking chamber 4 detected by the temperature detecting means 9 immediately after the start of cooking. Is done.

  FIG. 4 is a process diagram showing still another example of control of the cooking device in the present embodiment. This will be described below with reference to the process diagram of FIG.

  During the rice cooking process, the rotation speed and rotation speed of the blades 1 are controlled by the temperature of the cooking chamber 4, but even if a predetermined time (t1) elapses after the start of operation, the temperature detection means 9 detects the cooking chamber 4. When the temperature does not reach the first predetermined temperature θ1, the number of rotations of the blade 1 is small, and the glutinous rice in the cooking case 2 may not be sufficiently stirred and become uneven. Therefore, in the present control example, when the first predetermined temperature θ1 is not reached even after the predetermined time (t1) has elapsed, the energization rate of the driving means 3 is increased, and the rotational speed of the normal blade 1 or more is increased. The blades 1 are rotated for a predetermined time at the number of rotations. Thereby, the heating nonuniformity in the rice cooking process initial stage which arises when there are few rotation speeds of the blade | wing 1 can be prevented.

  Moreover, after a rice cooking process is complete | finished, although a user can be made to transfer to the process attached with the input means 7, when time passes without a user performing this operation, it energizes the heating means 5 and is a cooking case. You may make it hold | maintain at the optimal temperature for sticky rice in 2.

  In the above-described embodiment, the cooker having a mochi has been described as an example. However, bread may be made as an automatic bread maker, or a dough such as udon or pasta may be made.

  Moreover, the time of each process demonstrated in the said embodiment, the rotation speed of the blade | wing 1, etc. do not limit this invention.

  As described above, the cooker according to the present invention can make a stable and well-made rice cake in a short time by rotating the blade according to the heating state of the glutinous rice in the cooking case during the rice cooking process. Therefore, it can be applied to various cookers.
