Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall front view of the bread maker, and FIG. 2 is an overall explanatory diagram of the bread maker. Bread maker (1) top cover (2)
And an outer case (3), a lower case (4), an inner case (8), and a pan case (9). The mixing blade (11) provided in the pan case (9) is rotated by a motor (10). It is configured to be. The upper lid (2) is provided with a handle (12), and the upper lid (2) has a structure that can be opened and closed via a hinge (13) with respect to the outer case (3). In addition, a menu section (5) is provided on the front of the bread maker (1) so that menu input, menu display, and the like can be performed.

An exhaust duct (6) for releasing heat is provided above the outer case (3). The exhaust duct (6) is provided with a slide lever (7) for changing the opening amount. Further, the bread maker (1) has a blowing path (14), and has a structure capable of blowing hot or cold air during mixing or after firing. A heater (15) is arranged around the inner case below the inner case (8) so as to surround the pan case (9), and the heater (15) is a heater holder (16a) (16b).
Has been fixed by. In addition, around the heater (15), an adapter (17) for a steaming pan detachably attached to the bread maker body (1) is attached.

FIG. 3 is a perspective view of the steaming pan adapter (17), and FIG. 4 is a partial sectional view taken along line AA of FIG. The adapter (17) is composed of a cylindrical outer peripheral portion (18), an inner peripheral portion (19), and a bottom portion (20), and the inside thereof is a steam generating water storage portion (21). The adapter (17) is provided with a heater insertion recess (22) for contacting the heater (15).

An adapter fixing recess (23) is provided on the outer peripheral portion (18), and by fitting the heater (15) and the heater holder (16a), the adapter (17) can be used to make a pan. It is configured to be fixed around the bread case (9) inside the machine (1).

FIG. 5 is a functional block diagram of the bread maker (1), and FIG. 6 is a flowchart simply showing the operation of the bread maker (1). Hereinafter, description will be made according to this flowchart.

First, the user puts water and various bread ingredients into the pan case (9), mounts or removes the adapter (17), and adjusts the opening amount of the exhaust duct (6) for releasing heat by a slide lever. Adjust by (7). At this time, when the adapter (17) is attached, a certain amount of water is put into the steam generating water storage section (21) (step S-1). Then, a menu is selected by the menu section (5), and a start button (not shown) is pressed (step S-2).
At this time, the selection data is displayed on the menu section (5) which is also the menu display section (26) via the control section (24).

The bread maker (1) sends information selected by the menu section (5), which is a menu input section (25), to the control section (24), and the control section (24) bake the selected bread. It is determined whether the process is performed or the steaming process is performed.
(Step S-3).

The exhaust duct (6) is provided with a switch (27a) for detecting the open / closed state. The switch (27b) is turned on in a closed state and turned off when opened.
In the same way, switch (28
a) is provided, and a circuit (28b) is provided in which a switch is turned on in a mounted state and turned off in a non-mounted state. The water reservoir (21) of the adapter (17) is also provided with an electrode (29a) for detecting the presence or absence of a certain amount of water or more. When the water level becomes a certain amount or more, a current flows between the electrodes (29a). Is flowing and the switch is turned on, and if it is less than that, the electrode (29a)
The circuit (29) turns off because there is no water as a conductor between them. Each of these signals is a logic circuit (30)
Are output to the control unit (24) as a signal A and a signal B.

When this switch is turned on, each circuit (27b) (28b) (29b) outputs a signal of "1", and when each switch is turned off, each circuit (27b) (28b) (29b) ) "
A signal of "0" is output, and this signal is passed through a logical circuit (30) through a logical product circuit (30a) (30b), a negative logical product circuit (30c), and a logical product circuit (30d) having one of the negative inputs. When the exhaust duct is closed, the adapter (17) is attached, and the water level indicates a certain level or more, the signal A outputs "1", the exhaust duct is open, and the adapter (17) is not attached. If the water level is less than the predetermined amount even if the state is or the adapter (17) is attached, "1" is output to the signal B.
The control unit (24) determines this according to the discrimination information in the previous step.
In the case of the baking step, the signal B is selected and input, and in the case of the steaming step, the signal A is selectively input. If not, it is determined that the user is not ready (step S-4).

If the preparation is not completed, an alarm warning is issued (step S-5), and the bread making operation is stopped. If the preparation is completed, the operation time of each step for bread making (for example, primary mixing, rest, secondary mixing, fermentation, rounding, molding fermentation, heater heating) is called from the storage unit (31) and set. Is performed (step S-6), and information is sent to the drive control unit (32) so as to sequentially perform each step, and the drive control unit (32) performs a bread-making operation according to the information (step S-6).
-7), the bread making operation is terminated at the same time as the entire process is completed. During each fermentation step, the heater may be heated in the fermentation step, but this is for keeping the dough at 20 to 30 ° C. Even if water is contained in the water storage part (21), the amount of evaporation is small and there is no problem. .

In the above embodiment, the adapter using the detachable steaming pan (17) is shown. However, a structure in which the steam generating water storage section (21) is fixed to the main body of the bread maker (1) may be used. The shape is not particularly limited.

[0018]

Since the present invention is configured as described above, the following effects can be obtained.

By providing a water storage section near the heater,
Steamed bread can be made with one bread maker, and high quality steamed bread can always be obtained. In addition, by selecting whether to perform a steaming process or a firing process by menu input by providing a water storage amount, a water storage unit, and exhaust gas opening / closing detection means, if the preparation is not completed, the baking operation is stopped and Since it is possible to activate an alarm, it is possible to prevent the start of bread making and the failure of bread making before preparations are completed.
