The lower lid a33 was made of resin, and the lower lid b35 was made of metal. Further, the space 3 formed by the upper lid 36, the lower lid a33, and the lower lid b35
7 was separated by a rib 38 provided on an upper lid 36.

Problems to be Solved by the Invention In such a conventional automatic bread maker, the lower lid a33 and the lower lid b
Because the space 35 is divided and the space 37 is divided by the ribs 38, the temperature of the portion where the lower cover a33 is located is lower than the temperature of the portion where the lower cover b35 is located. For this reason, when steam emitted during baking the bread leaks from between the cooking chamber 34 and the lower lid b35, there is a problem that the lower lid a33 cools down and condenses on the storage unit 32.

Accordingly, a first object of the present invention is to provide an automatic bread maker having a simple structure and which does not cause dew condensation on a storage unit. The second object is to prevent a large amount of water vapor leaking from the shape of the lower lid from flowing toward the storage section, and to increase the strength of the flat portion of the lower lid. Third, the object is to increase the strength between the drawn shape portion and the flat portion of the lower lid. The fourth object is to stabilize the dimensions and flatness of the lower lid by preventing extra force from acting between the drawn portion and the flat portion of the lower lid in the assembled state.

Means for Solving the Problems In order to achieve the above object, the present invention forms a lower lid covering a cooking chamber and a storage section with a series of materials, and comprises a series of hollow spaces between the lower lid and the upper lid. Then, a groove is provided on the outer periphery of the flat portion of the lower lid with a gap from the drawn portion, a cut-and-raised portion is provided at a position of the gap between the groove portion and the drawn portion, and a hole provided in the cut-and-raised portion is formed in the gap. It is shifted from the position in the left-right direction.

In the present invention, the lower lid that covers the cooking chamber and the storage section is formed of a series of materials, and the space between the lower lid and the upper lid is formed of a series of hollow spaces, so that the steam leaking from the cooking chamber is rapidly cooled. This can prevent the occurrence of dew condensation on the storage section. In addition, by providing a groove in the flat part with a gap from the throttle shape part, the strength of the lower lid is increased, and the flow of water vapor is suppressed in the part of the gap to prevent a large amount of water vapor from flowing into the storage part. it can. further,
By disposing the cut-and-raised portion provided on the outer periphery of the lower lid at a position with a gap, the strength between the drawn portion and the flat portion can be increased, and the lower lid can be prevented from being deformed during handling.
Also, by shifting the cut-and-raised hole provided at the gap position from the gap position to the left and right, no extra force acts between the drawn shape part and the flat part of the lower lid when assembled. Part deformation can be prevented. Therefore, the dimensions and flatness of the lower lid are stable, the tightness between the cooking chamber and the lower lid is improved, and excess leakage of heat and steam can be prevented.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 and 2, reference numeral 1 denotes an electric motor. The rotation of the electric motor 1 is transmitted to a kneading blade 5 in a kneading container 4 mounted in a cooking chamber 3 via a belt 2. 6 is a kneading container 4

And a main body cover provided above the cooking chamber 3. The main body cover 7 is provided with a storage section 9 for receiving a measuring spoon 8 and the like beside the cooking chamber 3. Body cover 7
Is covered with a lid 10, and the lid 10 has a lower lid 11 and an upper lid.
Consists of 12 parts. The lower lid 11 is composed of a squeezed portion 11a for closing the cooking chamber 3 and a flat portion 11b for covering the storage portion 9.
Then, the drawn shape portion 11a and the flat portion 11b are made of the same series of materials. A series of hollow spaces 13 are formed between the lower lid 11 and the upper lid 12. Reference numeral 14 denotes an air hole provided around the throttle-shaped portion 11a.

Next, the operation and operation of the configuration of the embodiment will be described. First, bread materials such as flour and water are put in a kneading container 4 in which kneading blades 5 are set, mounted on the cooking chamber 3, and the lid 10 is closed. Then, when the switch is turned on and energized, the electric motor 1 rotates, and the rotation is transmitted to the kneading blades 5 in the kneading container 4 via the belt 2 to knead the bread material and produce the dough. And after fermenting for a certain period of time, heater 6
And the material in the kneading container 4 is fired. At this time,
Excess moisture in the ingredients turns into steam and the cooking chamber 3 and lower lid
A part leaks from between 11 and a part enters the lid 10 through the air hole 14, and the others leak in all directions. Storage section 9 and lower lid
During the period of 11 the air flow is slow and condensation forms if the water vapor is cooled rapidly. However, a flat part covering the storage part 9
Since 11b is made of a series of materials connected to the squeezed portion 11a covering the cooking chamber 3, the temperature of the flat portion 11b covering the storage portion 9 rises with firing. Further, since a series of hollow air 13 is also provided between the lower lid 11 and the upper lid 12, the air is warmed as a whole and the temperature rises with firing. As a result, the temperature also increases between the storage section 9 and the flat section 11b, the leaked water vapor is not suddenly cooled, and there is no condensation on the storage section 9.

In the embodiment shown in FIG.
The groove 15 is provided in the plane part 11b with an opening 1c, and the plane part 11b
The strength can be increased as compared with the case where is simply a planar shape. Further, since the gap 11c is provided, the steam leaking from the cooking chamber 3 is blocked by the gap 11c and escapes toward the air hole 14, so that the inflow of the steam into the storage portion 9 is reduced. Therefore, in addition to the effect of the above-described embodiment, dew condensation on the storage unit 9 is eliminated.

In the embodiment shown in FIG. 4 and FIG.

Then, in this embodiment, the cut-and-raised b17 is formed by
By providing at the position of the gap 11c between 1a and the groove portion 15, the strength of the gap 11c is increased, the lower lid 11 can be hardly bent at the upper portion 11c, and the lower lid 11 is deformed during handling and cooked. There is no large gap between the chamber 3 and the space.

Also, if the width of cut-and-raised a16 is widened or connected like cut-and-raised b17, cut-and-raised a1
The spring property of 6 increases, and the assemblability when inserting the lower lid 11 into the upper lid 12 deteriorates, but by cutting and raising only b17 and making it wider than the width of a16, drawing without impairing the assemblability, Bending can be prevented over a wide portion of the shape portion 11a and the groove portion 15.

Further, by shifting the hole 18 provided in the cut-and-raised b17 from the position of the gap 11c in the left-right direction, even if the hole 18 is pulled by the fitting claw 19 when the upper lid 12 and the lower lid 11 are assembled, the lower lid
Since the bending force does not act on the position of the gap 11c of 11 and the lower lid 11 is not deformed, the dimensions and flatness of the lower lid 11 are stable, and the tightness between the cooking chamber 3 and the lower lid 11 is good. It is possible to prevent excessive leakage of heat and steam. Accordingly, it is possible to make delicious bread with good dew condensation and good fire.
