Abstract

PURPOSE:To attain proper automatic heating by automatically performing the excitation time setting for the first cooking and continuous cooking by the operation of a single cooking key. CONSTITUTION:In an oven toaster, for example, when an automatic key 9 is operated, a microcomputer 5 judges whether 5min have elapsed since the completion of the previous cooking, if 5min have elapsed, it judges as the first cooking and sets the total cooking time T to 210sec. If 5min have not elapsed, it judges as the continuous cooking and sets the time T to 140sec. After the time T is set, the computer 5 turns a heater output command 6 on, a relay 7 is closed, a heater 8 is excited to start cooking, subsequently when the time T elapses, the command 6 is turned off, the relay 7 is opened to stop the excitation of the heater 8, and cooking is completed. Branch points are shown as 210sec and 140sec, but the branch points may be set at two or three points or more instead of just one point, the change of the time T at each branch point can be also considered. The cooking time is thereby automatically modified, and constant finish results are invariably obtained.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a cooking device equipped with a heating source such as an electric heater. [Prior Art] Conventionally, a cooking device using an electric heater , a configuration as shown in FIG. 3 is known.

31st 'Ati, open toaster toaster automatic cooking? In the INIm block diagram, (1
) is a commercial power supply, and (2) is an electric heater control circuit, which is composed of a microcomputer (5) and a heater output command (6). (3) is an electric heater heating circuit controlled by electric heater control circuit +2), and relay (7),
Consists of an electric heater (8). In addition, (4) is the toast automatic key human power section, the first key is l and the consecutive key a
Consists of D.

In such conventional heating cooking, when performing automatic toast cooking, the user presses the toast automatic key manual part (4).
While inputting -, select the first key 01 for the first cooking, or select the continuous key a9 for continuous cooking. The contents of the selected key are sent to the microcomputer (5), and the microcomputer (5) issues a heater output command (6).
) is sent to the relay ()) of the electric heater heating circuit (3), and a heater output command (6) is sent to close the contact of the relay (7) for a certain period of time according to the selected key. ) is energized for the above specified period of time.

In this case, the fixed time of the heater output command (6) is set shorter when the consecutive key αυ is selected than when the first key 01 is selected (by Even in continuous cooking when the internal temperature is high, automatic cooking is possible by heating for an appropriate amount of time depending on the user's selection.

[Problem to be solved by the invention]

In such conventional heating cookers, the user must decide whether to cook for the first time or for continuous cooking, so any cooking within a few minutes of the end of the first cooking is considered to be continuous cooking. There was a problem in that the user's selection criteria as to whether proper heating could be achieved were unclear. In order to solve this problem, there is a method of checking the temperature inside the heating chamber using a temperature sensing element such as a thermistor and determining the appropriate heating time according to the temperature inside the heating chamber, but the equipment is expensive. There was a drawback.

This invention was made to solve these problems, and aims to provide an easy-to-use and inexpensive heating cooker.

[Means to solve the problem]

The heating cooker according to the present invention has a heating circuit connected to a power source, and a heating circuit that can be energized for one time by operating a cooking key.
The control circuit includes a control circuit that sets cooking for the first time and continuous cooking, and when the cooking key is operated within a certain period of time after the end of the first cooking, the control circuit determines that the cooking is the continuous cooking, and the control circuit determines that the cooking is the continuous cooking. The heating circuit is energized for a set period of time.

[Effect]

The heating cooker according to the present invention can determine whether to cook for the first time or continuously by using a single cooking key and perform proper automatic heating.

〔Example〕

Figure 1 shows a toaster oven which is an embodiment of this invention.
111 is a control block diagram of the automatic toast cooking of
The l1m circuit consists of a microcomputer (5) and a heater output command (6). (3) is an electric heater heating circuit (
3) and consists of a relay (7) and an electric heater (8). 114) is the toast automatic key human power department.

It consists of an automatic cooking key (9).

Next, the operation of this embodiment will be explained using FIG. 2.

FIG. 2 is a flowchart showing the operation of the embodiment shown in FIG. 1. When the commercial power is turned on, the start is shown in step α2, and the process waits in step 0 for reception of the automatic key (9). When the automatic key is accepted in step 01, the microcomputer-C5) determines in step I whether 5 minutes have passed since the previous cooking was completed.

If 5 minutes have passed, it is determined that it is the first time of cooking, and the time of full cooking is f'.
o"l Set T to step 9 as T=210 seconds.

If it is determined in step I that 5 minutes have not passed since the end of the previous cooking, it is determined that the heating chamber is still full and continuous cooking is being performed, and the total cooking time T is set to T=140 seconds in step 0e. In other words,
The total cooking time T (T=140 seconds) of continuous cooking is shorter than the total cooking time 1n17 ('l'=210 seconds) of the first cooking, and can be automatically stacked. After setting the total cooking time T, go to step 1 and turn on the heater output command (6) from the microcomputer (5), close the relay (), and energize the electric heater (8) to start cooking. Start. Step 0 [Yes], 09. In step 2, it is determined whether T time has passed since the start of cooking, and if T time has passed, the heater output command is turned off in step 2B, the relay (7) is opened, the electric heater (8) is de-energized, and cooking is started. Step to finish ■
. Then, the automatic cooking key (9) returns to the reception standby state again.

Although the above embodiment describes the automatic cooking of toasts using an open heating cooker, the present invention is not limited thereto, and can be applied to, for example, open-cooked pizzas, gratins, cutlets, and cakes. Furthermore, in the above example, the turning point is 5 minutes after the end of the previous cooking.
Continuous cooking with 2nd cooking T = 210 seconds? = 140 seconds.

It is also possible to set not only one branch point, but also two, three, etc., and change the time T each time.

〔Effect of the invention〕

As described above, according to the present invention, the automatic g4 heating cooker
Since the time settings for the first and continuous cooking can be automatically changed using a single cooking key in q, it is possible to provide an easy-to-use device that does not require the user to make selections, and the cooking time is automatically adjusted. This has the effect that cooking items can always have a constant finished result.
