CONSTITUTION:This machine is provided with a baking chamber 1 having a heater 2, a bread baking mold 3, a kneading blade 6 provided on an internal bottom part of the bread baking mold 3, a temperature detecting section 7 to detect temperature in the baking chamber 1 and a controller 19 to control the baking of bread by temperature from the temperature detecting section 7. Moreover, the controller 19 has a finishing process in which the heater 2 is energized electrically by a low power for a fixed time after the end of a baking process to stop the energization of the heater 2 when the temperature from the temperature detecting section 7 is down below a fixed time. As a result, electric energization is performed by the low power for a fixed time to keep fishing condition of the bread until the bread baking mold 3 is taken out of the baking chamber 1. When the bread baking molding 3 is taken out, the temperature from the temperature detecting section 7 drops below a fixed value in a short time thereby enabling the stopping of the electric energization of the heater 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic bread maker used at home.

[0002]

2. Description of the Related Art A conventional automatic bread maker will be described below with reference to the drawings.

In FIG. 5, reference numeral 1 denotes a baking chamber, which has a heater 2 arranged at a lower portion thereof and a bread baking mold 3 detachably mounted on an upper portion of the heater 2. Reference numeral 4 is a motor, and a kneading blade 6 is rotationally driven by a belt 5 that transmits the power of the motor 4. The outer surface of the baking pan 3 is provided with a temperature detecting portion that comes into contact with the outer surface and detects the temperature of the baking pan 3 for process determination and temperature adjustment. Reference numeral 8 is a lid that covers the baking chamber 1 so as to be openable and closable, and reference numeral 9 is a control device that controls the entire baking process. The operation unit 1
Reference numeral 0 denotes a signal for starting or canceling cooking to the control device 9 by operating a key switch, which is provided on the front surface of the bread maker main body together with a display section 11 having a display lamp for displaying the progress of cooking and the like. There is. Reference numeral 12 denotes a bread baking type switch which detects whether or not the baking type 3 is set.

In the automatic bread machine having such a structure,
As shown in FIG. 6, the cooking process at the time of baking the bread sounds an end buzzer at the end of the baking process, and if the person does not take out the baking bakery mold 3 from the baking chamber 1, it directly enters the finishing process, and the heater 2 is 30% for 10 minutes. Energize, then 2 for 20 minutes
After 0% energization and then 10% energization for 30 minutes, the state becomes non-energized, and during this period, the display unit 11 indicates that the finishing process is in progress.

If the baking pan 3 is taken out during this finishing process, the baking mold switch 12 detects this and finishes the finishing process, and it is in a standby state, that is, in the initial state when the power supply is first connected to this baking machine. In a state where the cancel switch on the operation unit 10 is operated to be turned on, all the actuators are stopped and are waiting for an input from the operation unit 10.

[0006]

However, the above conventional structure requires the baking type switch 12,
If the bread baking die switch 12 is simply omitted due to cost reduction or the like, even if the bread baking die switch 3 is taken out, it cannot be detected. Therefore, the finishing process cannot be automatically terminated, and the intermittent energization state of the heater 2 is continued for one hour, so that it is impossible to energize the heater 2 in the finishing process in consideration of safety. It was a thing. Therefore, if the bread is not taken out promptly after the baking process, there is a problem that the bread is broken or becomes watery.

[0007] The present invention solves the above-mentioned problems of the prior art. Even if the bread-baking type switch is eliminated, the bread does not break or become watery, and there is no danger of burns and the like in a safe automatic bread machine. The first purpose is to provide

A second object is to improve convenience by omitting one switch operation so that it can be automatically placed in a standby state without operating the cancel switch of the operation section in the finishing process. ..

[0009]

In order to achieve the above object, a first means for solving the problems of the present invention is a baking chamber having a heater, a bread baking mold detachably mountable in the baking chamber, and the baking pan. The control is provided with a kneading blade provided on the inner bottom of the mold and driven by a motor, a temperature detecting unit for detecting the temperature in the baking chamber, and a control device for controlling bread baking according to the temperature from the temperature detecting unit. The device has a finishing process in which the heater is energized with low power for a certain period of time after the firing process is completed, and the energization of the heater is stopped when the temperature of the temperature detection unit falls below a certain temperature. ..

Further, in the second means for solving the problems, the control device is configured such that, in the finishing process after the completion of the firing process, the finishing process is terminated and the standby state is reached at the time when the energization of the heater is stopped. is there.

[0011]

According to the present invention, since the heater is energized with low power for a certain period of time while leaving the finishing process even if the baking-type switch is eliminated, the bread is prevented from breaking or becoming watery. While you can
Since the temperature in the baking chamber immediately drops to a constant temperature after taking out the bread baking mold from the baking chamber, energization of the heater can be stopped in a short time.

Further, it is possible to omit a single switch operation (operation of the cancel switch) by automatically controlling the standby state after the heater is de-energized.

[0013]

When t exceeds 60 minutes, (j) the heater 2 is energized to 0% and (k) energization is stopped, but the state continues the finishing process.

When the lid 8 is opened and the bread baking mold 3 is taken out during this period, the air in the baking chamber 1 is replaced with the outside air, so that the line 2 in FIG.
As shown by the dotted line, the temperature θ of the temperature detector 7 decreases rapidly, and when θ becomes θ1 or less, the heater 2 is energized with 0% (k).
Next, the power supply stops. However, until the cancel key is pressed, the display of the finishing process is continued, and when the cancel key is pressed, (l) and (m) the display of the finishing process disappears and the standby state is entered. This means that the user clearly recognizes that cooking has been completed by operating the cancel key.

Next, the operation of the second embodiment will be described with reference to FIG. 4. After the end buzzer sounds, the finish stroke is entered, and the duty of the heater 2 changes depending on the time t after the finish stroke. It is the same as the flow chart of FIG. 3, and when the temperature θ of the temperature detection unit 7 decreases and becomes less than θ1 (n) after opening the lid 8 and taking out the bread baking mold 3, the heater 2 is energized by 0% and the energization is stopped. With (p), the finishing process is completed and the machine enters the standby state.

[0022]

As is clear from the above description, the automatic bread maker of the present invention is a heater that does not have a conventional baking type switch when the baking type is taken out of the baking chamber after the bread is prepared. Power is automatically turned off after a few minutes without continuing to turn on electricity for a certain period of time, so it does not impair the finish of the bread and moreover it can prevent the risk of burns etc. and is highly safe. Will be things.

Further, when the finishing process is finished at the same time when the power supply is stopped and the standby state is set, the standby state is automatically set without operating the cancel key after the baking pan is taken out, so that one key operation can be omitted. It will be convenient.
