Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bread baking apparatus that heats a bread baking mold with a heater.

BACKGROUND OF THE INVENTION Conventionally, this type of bread baking apparatus has generally had a structure as shown in FIG.

That is, the structure was such that a bread baking mold 2 was provided in a baking chamber 1, an upper heater 3 was provided above the bread baking mold 2, and a lower heater 4 was provided below the bread baking mold 2.

In addition, conventional automatic bread making machines, for example,
As shown in Publication No. 28, it had a structure as shown in FIG.

That is, a bread baking mold 8 is provided inside the baking chamber 7, and a heater 9 is provided on the outside.The heater 9 heats the entire baking chamber 7, and the control circuit 1o controls the temperature to bake the bread 11. It was something.

Problems to be Solved by the Invention However, in the configuration shown in FIG. 6, the heaters are divided into 3 degrees for the upper heater and 4 for the lower heater, resulting in high parts costs and problems in that it takes a lot of time to assemble. Furthermore, since the upper heater 3 is close to the top of the bread 6 and the temperature of the upper heater 3 is high, uneven baking may occur on the top of the bread 6. Furthermore, it was necessary to separately control the energization of the upper heater 3 and the lower heater 4, or to switch them manually.

Further, due to the structure of the upper heater 3 and lower heater 4, the lid 6 can be opened and closed horizontally to prevent burns, making it difficult to set the bread baking mold 2.

In addition, in the automatic bread making machine shown in FIG. 6, since the heater 9 is located outside the baking chamber 7, the temperature of the bread 11 rises slowly, resulting in a long baking time and a thick crust of the bread. In addition, the outer shell 12 easily became hot to the touch, and even though it was covered with a heat insulating material 13, it was still hot to the touch. 1 more bread
Because there was no heat source on the top of bread 11, the top of bread 11 was undercooked and turned white, resulting in an unbalanced baked color. In addition, since the heater 9 is wrapped around the outside of the firing chamber 7 with mica or the like interposed therebetween, there may be assembly variations, and the degree of thermal contact between the firing chamber 7 and the heater 9 may change over long periods of use, resulting in variations in firing. Was.

The present invention solves these conventional problems and provides a bread baking apparatus that is capable of reliable baking and is easy to use.

They are arranged under the extension of the side surface of the bread baking mold 24, and the interval 26 is larger on the longitudinal side of the bread baking mold 24, and the dimensions are 26 to 45 mm.

Furthermore, the heater 23 is connected to the bottom of the bread baking mold 24 and the baking chamber 2.
It is located between the bottom surface of 6 and the bottom surface of 6. In addition, the temperature sensing section 27
is a position where the heater 23 is not placed below.
It is fixed to the side surface of the firing chamber 26 where the power terminal is located, and the ambient temperature inside the firing chamber 26 is sensed and the input to the heater 23 is controlled by the circuit 28 to perform temperature control. Here, even if the heater 23 is located below the side surface of the bread baking mold 24, the distance 26 allows bread 29 to be baked with good color balance and less uneven baking.

FIG. 3 shows a third embodiment, in which the heater 30 is a glass tube heater that has a coiled heater wire inside and whose outer surface is made of glass, ceramic, etc. Facing the gap 33 between the side surface and the side surface of the bread baking mold 32, two of them are arranged on the longitudinal side of the bread baking mold 32 below the extension of the side surface of the bread baking mold 32.
3 is 26-46 tma. The temperature sensing section 34 senses the temperature by contacting the bottom surface of the bread baking mold 32, and controls the temperature by controlling the input of the heater 3o with the circuit 36. In particular, the two heaters 3o are electrically connected in series, so that the temperature can be controlled by one input control circuit, and bread 36 with well-balanced browning and less uneven baking can be provided.

Next, another embodiment of an automatic bread maker using the bread baking apparatus of the present invention will be described.

FIG. 4 shows an automatic bread maker according to the fourth embodiment.
7 is the main body, 38 is a chassis, a motor 39 and a firing chamber 40
The bread mold holder 41 is fixed thereto. A small pulley 42 is fixed to the motor 39, and a large pulley 44 is connected to the motor 39 via a belt 43.
Pulley shaft 45. Power is transmitted to the lower connector 46. Inside the baking chamber 4o, there is a bread baking mold 48 equipped with a removable kneading blade 47, and a blade shaft 6o and a connector top 61 are pivotally supported on a bread mold holder 49 fixed to the bottom of the bread mold 48.
It is removably fitted to the bread-shaped pedestal 49.

Also, the distance between the side surface of the baking chamber 40 and the side surface of the bread baking mold 48 is 6.
A heater 63 is disposed at 2, and a temperature sensing section 64 is fixed to the firing chamber 40 at an upper position where the heater 53 is not disposed. This temperature sensing portion 64 is elastically supported and is in pressure contact with the side surface of the bread baking mold 48.

Furthermore, there is a lower cover 65 and an upper lid 66 above the firing chamber 4o,
The water container 57 set on the lid top 66 has a valve 68 and a spring 5.
9 is attached, the valve 68 is opened by the operation of the solenoid 6o, and the water in the water container 67 enters the bread baking mold 48.

Next, to explain the operation of this embodiment, ingredients such as flour, yeast, sugar, and salt are put into the bread baking mold 48, and the circuit 6
When the panel 62 at the top of 1 is operated, the motor 39 is first rotated by the operation of the circuit 61, and the training 9 is started by power transmission.
The blades 47 are rotated to stir the ingredients, and the solenoid 6o is operated to start supplying water into the bread baking mold 48 to start kneading. When kneading is completed, the heater 53 is energized and the fermentation proceeds through primary fermentation, secondary fermentation, and shaping fermentation. During this fermentation process, the motor 39 is slightly rotated to remove gas. After shaping and fermenting, this device automatically performs everything from kneading to baking, with a buzzer sounding to notify you of the completion of the fermented bread 63.

Since the heater 63 is located in the baking chamber 4o and the heat mass is small, the temperature rises quickly and the bread can be baked in a short time, and the temperature of the main body 37 rises, making it safe for human contact. . Furthermore, when stirring the ingredients for kneading, the materials are scattered and contaminate the firing chamber 4o, but since the heater 63 is fixed almost floating in the space inside the firing chamber 40, it is easy to clean, and the scattered materials can be easily removed from the heater. There are no negative effects, and there is little variation in bread making due to product variation or aging.

In addition, there are fewer parts that come into contact with the bread baking mold 48, the breadboard is covered in space, and there is no insulation material, so the rise in dough temperature during the kneading process is kept low, resulting in well-kneaded, high-quality bread. There is.

Also, in the fermentation process, by arranging the heaters 63 at intervals 62, the sides and bottom of the bread baking mold 48 are uniformly heated as explained in baking, and due to the convection of hot air,
By heating the upper part of the bread baking mold 48, the bread dough can be fermented evenly and evenly.

Effects of the Invention The present invention reduces the number of parts around the heater by locating the heater under the extension of the side of the baking mold, and also reduces the number of parts for the heater input switch or control circuit as well. This reduces assembly man-hours and significantly reduces costs.

In addition, when baking bread, the sides and bottom of the bread are heated by the heater's direct radiant heat and convection, which increases the ambient temperature in the baking chamber, and the bread baking mold conducts heat, resulting in less uneven baking. The indirect radiant heat from the heater due to the distance between the side walls of the baking chamber and the heat convection of the hot air result in less variation in surface temperature and less uneven baking. Therefore, when looking at the baked state of the bread as a whole, it is possible to provide bread with a well-balanced baked color and high quality both in appearance and internal appearance.
