In the case of 5, the flange 41 provided on the outer periphery of the upper end is supported by the inner pot support sleeve 2, and is held to maintain a plurality of slits between the bottom portion and the inner wall of the peripheral wall and the inner pot accommodating portion 5.

Next, the action of the electronic pot of the present embodiment configured as described above will be described.

First, the quantified food consisting of rice 43 (such as white rice) and water 44 The material 42 is placed in the inner pot 40, and is housed in the inner pot accommodating portion 5, and the lid body 30 is closed. At this time, the lid switch detecting unit 19 detects that the lid body 30 is closed, and transmits the detection signal to the control unit 16. In addition, since the inner pot 40 is housed in the inner pot accommodating portion 5, the weight detecting device 10 is pressed, and the inner pot detecting device 8 confirms that the inner pot 40 is actually placed. At this time, the current time is usually displayed on the display unit 25.

When the operation start portion 21 is operated in this state, the high-frequency current controlled by the control portion 16 is supplied to the induction heating coil 6 to generate an alternating magnetic field, the inner pot 40 is induced to be heated, and the cooking of the food material 42 is started. rice. Then, after the preheating process, the rice cooking process, the simmering process, and the cooking process, the heat transfer process is carried out (hereinafter, the cooked food material 42 is referred to as rice 45).

At this time, from the state in which the food material 42 is cooked, the weight detecting device 10 detects the total weight W0 of the inner pot 40 including the rice 45, and transmits the detection signal to the control unit 16.

Then, the lid body 30 is opened (the lid switch detecting portion 19 detects that the lid body 30 is opened and transmits the detection signal to the control portion 16), and when the rice 45 is placed in the bowl, When the weight detecting device 10 detects the load W2 at this time, if the W2-W0 is a positive value, the control unit 16 determines that a certain amount of rice is taken out from the inner pot 40, and switches the display content of the display unit 25 to rice. 45 intake of calories. Then, the weight detecting device 10 detects the weight of the rice 45 (in the bowl) taken out from the inner pot 40, in other words, the weight W1 of the remaining rice 45 including the inner pot 40.

The control unit 16 multiplies the amount W (i.e., W0-W1) of the rice 45 by the energy e (cal/g) per unit weight of the rice 45, based on the rice 45. The amount of calculation energy E1=e*W is calculated to calculate the calorific value (kcal) until the lid switch detecting unit 19 detects that the lid body 30 is closed, as shown in FIG. 3, on the display unit 25 of the operation unit 20. The amount of calorie intake (kcal) is automatically reported by digital display. The figure shows that the calorie intake is 178 kcal. Further, when the lid switch detecting unit 19 is not provided, the intake heat is digitally displayed on the display unit 25 at a specific time after the rice 45 is taken out.

As described above, the reason why the weight detecting device 10 detects the load W1 when the rice 45 is placed in the bowl will be described. First, in the present invention, since a dedicated operation button is not required, it is not known whether the rice 45 is moved from the inner pot 40 when the lid body 30 is opened, and the total weight of the inner pot 40 is detected at the time when the lid body 30 is opened. W0, however, the display unit 25 still displays a general display such as time display.

In this state, when the rice cooker is placed in the inner pot 40 and the load of the inner pot 40 is caused, the weight detecting device 10 detects the load W2 and transmits the detection result to the control unit 16. When W2-W0 is a positive value, the control unit 16 determines that the rice 45 has been removed from the inner pot 40, and switches the display content of the display unit 25 from the normal display to the display of the calorific value.

Then, as described above, the weight W of the rice 45 taken out from the inner pot 40 is used to calculate the calorie intake amount, and the intake heat is digitally displayed on the display unit 25 before the lid body 30 is closed. When the lid body 30 is closed, the display content on the display unit 25 is restored to a normal display such as time indication.

Then, when the rice 45 is taken out from the same inner pot 40 for the second time and the third time, the control unit 16 memorizes the total weight W1 of the inner pot 40 containing the rice 45 after the first rice 45 is taken out. Then, it is detected that when the cover 30 is opened When the second rice 45 is used, the load W2 applied to the inner pot 40, if W2-W1 is a positive value, it is determined that the rice 45 is taken out again, and the content of the display unit 25 is switched to the calorie intake, according to the above method. The intake heat is calculated based on the amount of the rice 45 taken out, and the number is indicated on the display unit 25 while the lid 30 is opened. The effect of taking rice 45 after the third time is the same.

According to the present embodiment, when the user takes out the rice 45 from the inner pot 40 (during the bowl to the bowl), the energy E1 of the extracted rice 45 is taken as the calorie intake amount (kcal), and the display unit is displayed while the lid body 30 is being opened. 25 automatic display, therefore, it is not necessary to operate a dedicated operation button at this time as in the conventional case, and the user can easily confirm the calorie intake, thereby enhancing health awareness and suppressing excessive calorie intake.

[Embodiment 2]

In the electronic pot of the first embodiment, the heat of intake (kcal) of the rice 45 taken out from the inner pot 40 by the speaker 18 as the notification device is reported by sound (for example, "00 calories").

In the present embodiment, since it is not necessary to numerically display the amount of heat taken by the rice 45 taken out from the inner pot 40 on the display unit 25, it is not necessary to change the display content of the display unit 25. Therefore, it is used to judge whether or not the detection of the load W1 when the rice 45 is in the bowl is to be notified by voice. In the same manner as in the first embodiment, when the rice cooker is placed in the inner pot 40 and the internal pan 40 is loaded, the weight detecting device 10 detects the load W2 and transmits the detection result to the control unit 16. When the control unit 16 has a positive value of W2-W0, it is determined that the rice 45 is removed from the inner pot 40. And judged to be voice notification. Following it, The weight detecting device 10 detects the weight W2 of the inner pot 40 containing the rice 45 after the rice 45 is taken out from the inner pot 40, and calculates the take-out amount of the rice 45 based on W0-W2.

According to the calculation procedure of the calorie intake (kcal), the calculation result is converted into a voice, and the calorie is reported by the voice during the period in which the lid 30 is opened.

According to the present embodiment, the electronic pan does not need to look at the display of the display unit 25, and it is possible to concentrate on the rice 45 (filling the rice into the bowl). Further, in the present embodiment, in addition to the sound notification by the speaker 18, the heat intake of the taken-out rice 45 may be digitally displayed on the display unit 25 according to the first embodiment.

In the first embodiment, the amount of heat intake (kcal) of the rice 45 is numerically displayed on the display unit 25. However, in the present embodiment, the display unit 25 displays the ingestion in a plurality of small segments. Heat.

In the present embodiment, in the lower portion of the display unit 25, an indicator 26 in which a plurality of segments composed of liquid crystals are arranged in the horizontal direction is formed as a notification means, and for example, "small amount" is displayed on one side (the left side of the figure). On the other side, "Multiple" is displayed.

In the present embodiment, as in the case of the second embodiment, the detection of the load of the inner pot 40 when the rice 45 is placed in the bowl can be omitted. In the same procedure, the calorie intake (kcal) of the rice 45 taken out is calculated, and the result is indicated by the indicator 26 in an analogous manner while the lid 30 is opened.

According to the present embodiment, the user of the electronic pot can intuitively understand the calorie intake of the rice 45 taken out based on the indicator 26, so that the health awareness can be further enhanced. Further, in the present embodiment, the intake heat of the rice 45 taken out may be numerically displayed on the display unit 25 as in the first embodiment, and the indicator 26 may be analogized.

In the above description, the case where the heat is taken in a small section such as a liquid crystal is described as an example. However, the indicator may not be represented by a liquid crystal or the like. For example, a plurality of light-emitting members may be used to constitute the indicator, which is the same as when the small segment is indicated. Intuitively understand the calorie intake, which in turn enhances health awareness.

In each of the above-described embodiments, the case of cooking the food material 42 (rice 45) composed of rice (white rice) 43 and water 44 will be described, but the ingredients other than white rice (for example, black rice, small bean rice, etc.) The energy value per unit weight is stored in the control unit 16 in advance, and the correct information on the calorie intake can be easily confirmed as in the case of white rice.
