Problem to be Solved by the Invention However, in such a conventional heating cooker, the volume of the material in the kneading container 4 continues to swell during the heating process of fermentation and baking after kneading, so that after baking is completed, the volume of the material in the kneading container 4 as shown in FIG. As shown in FIG. 2, the bread 12 spreads so as to come into close contact with the inside of the kneading container 4 and the rotating blades 6.

When taking out the baked bread 12 from the kneading container 4 in such a state, even if you remove the kneading container 4 from the heating chamber 1, turn the kneading container 4 upside down, and shake or hit it strongly, the bread 12 will not knead. There is a problem that it cannot be taken out from the container 4.

When the dough is baked, the temperature of the kneading container 4 is close to 150° C., and if the bread is left to cool down, the baking will proceed further and the bread will be overly burnt.

The operation of quickly removing bread from such a high-temperature kneading container was extremely difficult due to the risk of burns.

The present invention solves these conventional problems, and provides a cooking device that has a simple structure, allows baked bread to be easily taken out of a kneading container, and is easy to use.

Means for Solving the Problems The heating cooker of the present invention is provided with a heater as a heating device in a heating chamber in which food is stored and cooked, and a kneading container is detachably provided in the heating chamber. A rotary vane and a rotary coupler connected to the rotary shaft are provided at the bottom, and are driven by a rotary drive unit.The rotary shaft is equipped with a spring that always presses against the bottom of the kneading container. The rotating blade moves upward by pushing up the spring.

Function: The heating cooker of the present invention makes bread by kneading the ingredients in the kneading container, then fermenting and baking them, but the dough swells after baking and the bread sticks tightly to the kneading container. However, by pushing up the spring from the bottom of the kneading container, the rotating blades move upward. As this happens, the bread moves along with the rotating blade in the direction of being pushed out of the kneading container, and the bread is no longer in close contact with the bottom and sides of the kneading container.
Bread can be easily taken out of the kneading container.

In addition, since this spring normally acts to press the rotating blade against the bottom of the kneading container, it also acts as a seal to prevent liquids such as water from leaking out when placed in the kneading container. be.

FIG. 3 is a sectional view showing the state when bread is baked in the kneading container of the cooking device of the present invention.

When bread ingredients such as flour, yeast, and water are placed in the kneading container 26 and set in the heating chamber, the control section controls the motor and heater according to the bread making process.

First, the rotating blades 26 rotate to knead the materials. Next, the heating chamber is adjusted to the fermentation temperature and the yeast is fermented. As a result, the material in the kneading container becomes bread dough.

Once the bread dough is completed, the temperature inside the heating chamber is raised and baking begins. The bread dough continues to rise during the fermentation and baking process, and as shown in FIG.

At this time, the bread 36 is baked so as to come into close contact with the wall surface of the kneading container 24 and the rotating blade 26 due to its swelling.

Due to this close contact, it is extremely difficult to remove the baked bread 36 from the kneading container 24.

FIG. 4 is a sectional view showing an operation state in which baked bread is removed from the kneading container of the cooking device according to the present invention.

In FIG. 4, when the coupler 2 is pushed up by hand, the spring 34 is compressed, the shaft 27 moves upward, and the rotary vane 26 fitted thereto is lifted. By this operation, the baked bread 36 is also lifted from the kneading container 24 together with the rotary blade 26, and once the bread 36 and the kneading container 24 are no longer in close contact with each other, the bread 36 can be easily taken out by simply pulling it out. Become. In FIG. 4, the kneading container is shown in an upright position, but it will be easier to take out the dough if the kneading container is turned upside down.

FIG. 5 is a sectional view showing another embodiment of the kneading container of the heating cooker according to the present invention.

In FIG. 5, a push-up plate 40 is provided in addition to the shaft 38 and rotating blades 39 provided in the kneading container 37. The push-up plate 40 is placed in close contact with the bottom of the kneading container 37 and is connected to a shaft 41. A compression spring 43 is installed between the shaft 41 and the stand 42 to keep the push-up plate 40 up and down the kneading container 37.
is pressed down to the bottom side. By manually pushing up the shaft 41, the spring 43 contracts and the push-up plate 40 rises to the position shown by the two-dot chain line.

By this operation, the baked bread is pushed up and removed from the kneading container.

Effects of the Invention As described above, since the heating cooker of the present invention has a structure in which the rotary blades or the push-up plate are movable in the axial direction, it has many practical effects as described below, although it is a partial structure. can demonstrate.

(1) Baked bread expands in the kneading container and sticks tightly to the container, making it extremely difficult to take it out.However, according to the present invention, it can be rotated by simply pressing the connector with your finger. Since the blade lifts up and pushes directly up from the r of the bread, the adhesion between the bread and the container is reliably broken and the bread can be easily taken out, making it possible to realize an extremely user-friendly heating cooker.

If you leave the kneading container until it cools down, the remaining heat in the container will advance the baking of the bread, eliminating the problem of over-burnt bread.

(2) Since the bread can be taken out easily, there is no need for dangerous operations such as strongly shaking or tapping a hot kneading container, which was required in the past, and the operation is highly safe and there is no fear of burns. , it becomes easier to use from this aspect as well. In addition, since the bread can be easily taken out, there is no need to make mistakes such as deforming the bread when taking it out, and it is possible to heat the bread in a well-baked shape.

(3) In addition to flour, the kneading container is often filled with liquid substances such as water, eggs, and milk.Also, the kneading container is often left in this state for a long time, and then the timer is set to start kneading after a certain amount of time has elapsed. A seal structure is extremely important to prevent this liquid material from leaking from the kneading container, but since the shaft is constantly pushed downward by the spring, the sealing member and This means that the upper part of the shaft is always kept in close contact, ensuring a reliable seal.
A highly reliable heating cooker that does not cause malfunctions due to liquid leakage.

(4) As shown in Figure 5, if the push-up plate is provided separately from the rotary vane, the configuration of the rotary vane, shaft, bearing, etc. can be shortened, and the height of the stand can be lowered, resulting in a compact kneading container. can do.

In addition, by using it in combination with a push-up plate or by providing a plurality of push-up plates, it is possible to make it easier to take out the bread.

(5) Since the coupler is always pushed down by the spring, the coupler on the main body side and the coupler on the kneading container side are always pressed together and connected, making it possible to connect the rotation more reliably. In addition, if there is a gap or rattling in the shaft part, it may cause noise such as vibration noise, but since the spring is biased in one direction, rattling in the shaft part can be visually monitored, and vibrations can be caused. This means that a quiet heating cooker with less noise can be realized.

As mentioned above, the simple configuration has many effects,
To provide a convenient and easy-to-use heating cooker.
