Description

The present invention relates to a high frequency heating cooker.

In some cooking menus using a conventional high-frequency heating cooker, cooking is completed by adding a seasoning to the object to be heated and stirring it after the heating control is completed. For example, carbonara is made by mixing eggs, seasonings, etc. with pasta that has been warmed by heating control. Patent Document 1 describes a cooking cooker provided with a speaker unit that outputs a heating end notification sound for notifying that heating by the heating unit has ended.

FIG. 5 is a flowchart showing heating control. Here, Napolitan will be described as an example. First, the user places a container containing pasta, vegetables, bacon, water, etc. in the heating chamber 2.

<Step S101>
It detects whether or not the start key (not shown) of the operation unit 6a is pressed.

<Step S102>
If YES in step S101, the weight sensor 5 measures the weight of the food to be heated placed in the heating chamber 2 and transmits it to the control means 9. The control means 9 calculates the heating time of the object to be heated by using the weight information. The control means 9 may substitute the heating time preset for each cooking menu without calculating the heating time using the weight information.

<Step S103>
The control means 9 controls the electric power supplied from the inverter circuit of the inverter board 8 to the magnetron 7. As a result, the food is heated by the microwave supplied from the magnetron 7. Then, the control means 9 starts measuring the cooking time after the heating is started.

<Step S104>
The control means 9 determines whether or not the first predetermined time has elapsed. Until YES in step S105, in other words, until the first predetermined time elapses, it is a heating time for the purpose of heating the foodstuff in the container at once. The heating output here is W1. That is, the control means 9 instructs the inverter board 8 so that the heating output becomes W1 until the first predetermined time elapses.

<Step S105>
The infrared sensor 39 measures the temperature of the food in the heating chamber 2 and transmits it to the control means 9. The control means 9 uses this temperature information to calculate the time until the food reaches a predetermined temperature, and uses that time to recalculate the time until the heating is completed. That is, the control means 9 calculates the time related to the second predetermined time by using the infrared sensor 39.

<Step S106>
The control means 9 determines whether or not a second predetermined time has elapsed from the start of heating. The second predetermined time is a time that changes based on the time until the heating is completed recalculated in step S105. That is, when it is calculated in step S105 that the remaining 90 seconds are reached until the predetermined temperature is reached, the time from the recalculation to the second predetermined time is 90 seconds. By recalculating the time in step S105 in this way, the heating time can be varied according to the state of the food material, and the finish after the end of the second predetermined time can be kept constant.

Until YES in step S106, that is, until the second predetermined time elapses, it is a heating time for the purpose of slowly heating the foodstuff in the container in order to bring it into a desired state.

Assuming that the heating output in step S106 is W2, the control means 9 instructs the inverter board 8 so that the heating output becomes W2 until the second predetermined time elapses. Here, it is desirable to instruct W1> W2. As a result, overheating of the food material can be suppressed and an appropriate heating state can be maintained.

<Step S107>
If YES in step S106, the control means 9 instructs the notification unit 34 to play a notification sound in order to inform the user that the time for adding the seasoning or the like has been reached. That is, the control means 9 instructs the notification unit 34 to perform the first notification after the lapse of the second predetermined time.

Further, the control means 9 instructs the display unit 6b to display information indicating that it is time to add the seasoning or the like. Then, the control means 9 instructs to stop the heating control. That is, the control means 9 instructs the magnetron 7 and the inverter board 8 to stop heating the object to be heated from the instruction to give the first notification until the start key is pressed. do.

For the notification in step S107, the notification unit 43 or the operation / display unit 44 of the terminal device 61 may be used.

<Step S108>
The user opens the door 3, puts the seasoning in the container in the heating chamber 2, and closes the door 3. For example, put ketchup in a container and mix. Then, the user presses the start key of the operation unit 6a again. In step S108, it is detected whether or not the start key is pressed.

Here, a method is conceivable in which the door open / close sensor (not shown) provided in the heating cooker Z detects that the door 3 is closed, so that the heating control is restarted even if the start key is not pressed. However, if the heating control is started by closing the door 3, if the door is opened and closed without putting the food material into the heating chamber 2, there is a possibility that the door 3 operates in a no-load state. On the other hand, such a situation can be avoided by restarting the heating control by pressing the start key.

<Step S109>
If YES in step S108, the preset heating control is restarted. The third predetermined time, which is the heating time from step S109 to step S110, is calculated by the control means 9 based on the weight of the food measured by the weight sensor 5 in step S102.

The third predetermined time may be calculated based on the weight measured by the weight sensor 5 at the time of step S109. In this case, since the weight of the food material at the time of step S109 is the food material containing the seasoning, the heating time includes the increase / decrease of the seasoning added. However, instead of the calculation method, the third predetermined time is based on the weight of the food measured by the weight sensor 5 in step S102, that is, the weight measured by the weight sensor 5 by the time when the first predetermined time elapses. May be calculated. As a result, the food can be heated in the originally required heating time regardless of the increase or decrease in the seasoning.

Further, the control means 9 may calculate the third predetermined time based on the temperature rise rate of the infrared sensor 39 in step S109. As a result, for example, when the temperature of the food has dropped due to the user taking time to add the seasoning or the like in step S108, the food can be heated to a temperature desirable for the user.

Assuming that the heating output in step S109 is W3, W1> W2 ≦ W3 is desirable. As a result, the finished state of the food material at the end of step S110 can be kept constant.

<Step S110>
When the third predetermined time is reached, the control means 9 instructs the inverter board 8 to stop the oscillation of the microwave from the magnetron 7. Then, the control means 9 instructs the notification unit 34 to play a notification sound in order to notify the user that the cooking has been completed. That is, the control means 9 instructs the notification unit 34 to perform the second notification after the lapse of the third predetermined time. The notification sounds in steps S110 and S107 may have different notification contents (for example, different melody).
