Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic bread maker that can produce freshly baked bread simply by adding predetermined ingredients.

2. Description of the Related Art A conventional automatic bread maker has a structure as shown in FIG. 3, for example (Japanese Patent Application Laid-Open No. 56-3028).

That is, there is a kneading blade 3 in a bread baking mold 2 placed in a baking chamber 1 containing a predetermined material, and this kneading blade 3 is driven by a motor 4 to knead the predetermined material placed in the bread baking mold 2. Use as bread dough.

After the kneading, a heater 6 insulated and wound around the outside of the baking chamber 1 is energized, and the temperature and time are controlled by the circuit 6 to carry out fermentation and leaven the bread 7. After this fermentation, the pants are baked using the heater 6 while controlling the temperature and time using the circuit. At this time, high-temperature hot air comes out from the gap between the main body case 8 and the lid 9, which may accidentally cause a person to burn the pants. It will cause burns if you touch it.

Moreover, at this time, high-temperature hot air and steam generated inside the firing chamber 1 are not completely exhausted from the steam hole 10 provided in the lid 9, but are also leaked to the outside through the gap between the main body case 8 and the lid 9. It is something that will be lost. Therefore, if the opening of the steam hole 10 is made larger to prevent leakage from the gap between the main body case 8 and the lid body 9, the fermentation process time of the bread 7 will be longer, and since it will be heated by the heater 5, The surface of the bread 70 is dried by the outside air, and as a result, the bread 7 does not grow large and cracks occur, making it impossible to obtain high-quality bread.

Problems to be Solved by the Invention However, in the conventional configuration shown in FIG. It may leak outside and cause burns if people accidentally touch it.
Steam condenses and flows down the main body case, staining the product, condensed water flows into live parts and breaks the insulation, and even in the following abnormal situations, for example, if only water is accidentally poured into the product. However, when the circuit 6 fails and becomes continuously energized, there is a problem in that the main body case 8 is deformed by the high temperature air.

The object of the present invention is to provide an automatic bread maker that solves these problems.

Means for Solving the Problems In order to solve the above problems, the present invention provides a ceiling frame that is attached to the upper part of the main body case and supports the upper end of the firing chamber, and that protrudes upward from the upper surface of the main body case. A rib is provided, a heat exhaust hole communicating with the outside air is provided in the rib, and a lower lid of a lid body that covers the upper part of the main body case in an openable and closable manner overlaps the outer periphery of the rib.

Function According to the above structure, a rib provided on the top frame so as to protrude upward from the upper surface of the main body case is provided with a heat exhaust hole that communicates with the outside air, and furthermore, the upper part of the main body case can be opened and closed on the outer periphery of this rib. The bottom lid of the lid body overlaps the top of the lid, and the high-temperature air and steam generated inside the baking chamber when baking bread is much hotter than the outside air and has a lower specific gravity, so it does not rise. In this case, the main body is formed by the drift effect of thermal convection air as the temperature rises in the firing chamber, due to the above-mentioned configuration with heat exhaust holes and the overlap configuration between the outer periphery of the ribs and the lower lid of the lid body. Air from the bottom of the case flows out through the heat exhaust hole to the top, forming an air wall that can block high-temperature air and steam generated from inside the firing chamber.
This prevents high-temperature air and steam from leaking from the gap between the lid and the main body case, and prevents burns from coming into contact with such high-temperature air and steam, and prevents condensation of steam from condensing on the main body case. It can also prevent water from flowing down, and even during abnormal situations.

It is also possible to prevent the main body case from deforming due to hot air.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 and 2. In Figures 1 and 2, 11 is a chassis, and a main body case is attached to the chassis 11 and has a lower body 12 made of sheet metal, and a lower body 12 that is attached to this lower body 12 and molded from synthetic resin. It is composed of an upper body 13. A motor 14 is attached to the shear 711, and the rotation of this motor 14 is caused by a belt 16 that is placed around a small pulley 15 attached to a rotating shaft.
Power is transmitted to a dog pulley 18 rotatably attached to a bearing 17 press-fitted into the chassis 11, which rotates a lower connector 19 fixed to the dog pulley 18 by caulking or the like. There is a bread baking mold 21 inside the baking chamber 2Q whose bottom part is fixed to the chassis 11, and this bread baking mold 21 is connected to a bread baking mold stand 22.
The position is fixed by The bread baking mold 21 has a kneading blade 23 detachably provided on the upper connector 22 that contacts the lower connector 19 and transmits rotation. A heater 26, which is attached by screwing a fixed insulator 24 and a fixing metal fitting 26, and a sensor 27, which holds a thermistor inside, are attached to the side surface of the firing chamber 2o.

The ceiling frame 28 is attached to the upper part of the upper body 13 with screws, etc.
It also supports the upper end of the firing chamber 20. A heat shield plate 29 made of a metal plate whose surface is coated to reflect as much radiant heat as possible is provided with a gap between it and the outer surface of the firing chamber 20, and its upper part is inserted into the groove 30 of the ceiling frame 28.
In addition, the end face of the top frame 28 is brought into contact with the top frame 28 to prevent hot air from flowing out in the direction of the upper body 13 as much as possible. In addition, the lower part of the heat shield plate 29 is bent to connect the chassis 11 and the firing chamber 2o.
The firing chamber 2o and the chassis 11 are fixed by screwing together.

As shown in FIG. 2, the top frame 28 is provided with a lip 31 that protrudes upward from the upper surface of the upper body 13 constituting the main body case, and this lip 31 has a heat exhaust hole 32 that communicates with the outside air.
At the same time, an inclined surface 311L is formed at the upper part of the outer peripheral part.

Furthermore, a firing lid 3 that forms a firing space above the firing chamber 2o
3 is elastically attached to the lower lid 34 constituting the lid body,
The lower lid 34 is screwed to the upper lid 36 constituting the lid body, and the sloped surface 341L formed on the inner circumference of the lower lid 34 overlaps the sloped surface of the lip 31 when the lid body is closed. ing. A yeast container 36 is attached to the baking lid 33, and a valve 37 is attached to a hole in the yeast container 36 in the opening direction of the bread baking mold 21 so that it can be opened and closed, and is biased by a spring in the closing direction. A valve lever 38 is provided at one end of the valve 37, and a solenoid 39 is attached to the upper lid 36. A lever 40 is movably attached to the tip of the plunger of this solenoid 39, and when in operation, this lever 40 acts as a valve lever. 38 to open the valve 37.

An exhaust guide 41 is sandwiched and fixed between the upper lid 36 and the lower lid 34, and the lower lid 34 located below the exhaust guide 41 is open. Further, the baking lid 33 is provided with a steam hole 42 .

Next, to explain the operation of this embodiment, when ingredients such as water, flour, sugar, and salt are put into the bread baking mold 21 and the panel 43 having a circuit (not shown) is operated, the operation of the circuit first causes the motor 14 to Rotate.

The kneading blades 23 are rotated by power transmission to knead the materials. When this kneading is completed, the yeast 44 enters the kneading mode, and when the set time has elapsed, the solenoid 39 is activated, the valve 37 is opened, and the yeast 44 falls into the baking mold 21. After this, the motor 14 rotates again to knead the materials. When the kneading is completed, the heater 26 is energized to adjust the temperature of the bread baking mold 21, and the process proceeds to primary fermentation, secondary fermentation, and shaping fermentation. Between each fermentation, the motor 14 is slightly rotated to remove gas. After shaping and fermenting, the fermented bread 45 is baked by energizing the heater 26, and when the process is finished, a buzzer sounds to notify the finished product.In this way, everything from kneading to baking is performed automatically, so ingredients are added. You can make bread with just that.

Here, a lip 31 is provided on the ceiling frame 28 so as to protrude upward from the upper surface of the upper body 13 constituting the main body case, and a heat exhaust hole 32 that communicates with the outside air is provided in this lip 31,
Furthermore, a lower lid 34 of a lid body that covers the upper part of the upper body 13 in an openable and closable manner overlaps the outer periphery of this lip 31. It is much hotter than
In addition, the specific gravity is also light, so it rises, but in this case, the heat exhaust hole 3
2, and the configuration in which the outer periphery of the lip 31 and the lower lid 34 of the lid body overlap, the lower body 12 of the main case is formed by the triad action of thermal convection air as the temperature rises in the firing chamber 20. Since air from the bottom of the firing chamber 2o flows out to the upper part through the heat exhaust hole 32 and forms an air wall, high-temperature hot air and steam generated from inside the firing chamber 2o are blocked. Through these actions, it is possible to prevent high-temperature hot air and steam from leaking from the gap between the lower lid 34 that constitutes the lid body and the upper podium 13 that constitutes the main body case, and also to prevent these high-temperature hot air and steam from leaking. It is possible to prevent burns caused by contact with steam, steam condensing on the main body case and flowing down, and furthermore, it is possible to prevent the main body case from deforming due to hot air in abnormal situations.
