Description

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

Conventional technology A conventional automatic bread maker had a structure as shown in Fig.
Publication No. 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, the heater 5, which is 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 to rise the bread 7. After this fermentation, the bread 7 is baked by the heater 5 while controlling the temperature and time by the circuit 6, but 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 damage to people. It will cause burns if touched. 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, and the main body case 8 and the lid 9 are
It leaks outside through the gap between the 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 7 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. This can leak outside and cause burns if a person accidentally touches it, steam can condense on the main body case 8 and flow down, staining the product, or the condensed water can flow into live parts and destroy insulation. Furthermore, the main body case 8 may be deformed by high-temperature hot air in the following abnormal situations, such as when only water is added by mistake, or when the circuit 6 breaks down and becomes continuously energized. There was a problem.

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 lower lid of a lid body that covers the upper part of the main body case so as to be openable and closable is overlapped on the outer periphery of the rib, and a heat exhaust hole communicating with outside air is provided on the upper surface of the rib located above the overlapping part. It is something that

According to the above configuration, the lower lid of the lid body that covers the upper part of the main body case so as to be openable and closable overlaps the outer periphery of the rib provided on the ceiling frame so as to protrude upward from the upper surface of the main body case, and this overlap Heat exhaust holes are provided on the top surface of the ribs located above the bread baking chamber to communicate with the outside air. Since the specific gravity is also light, it rises.In this case, due to the overlapping structure between the outer periphery of the rib and the lower lid of the lid body and the structure of the heat exhaust hole provided on the top surface of the rib, heat convection occurs as the temperature in the firing chamber increases. Air from the bottom of the main body case formed by air drift flows out to the top through the heat exhaust hole and forms an air wall, which blocks high-temperature hot air and steam generated from inside the firing chamber. These actions prevent high-temperature hot air and steam from leaking from the gap between the lid and the main body case, and also prevent burns and burns caused by coming into contact with these high-temperature hot air and steam. It also prevents steam from condensing on the main body case and flowing down, and also prevents the main case from deforming due to hot air in abnormal situations. Heat exhaust holes are provided on the top surface of the rib located above the overlap with the lid, so even if water is accidentally spilled above the product, it is less likely that the water will flow into the main case. At the same time, since the air flowing out from the inside of the main body case to the heat exhaust hole has a flow velocity, due to the ventilee effect due to this flow velocity, outside air flows into the internal space of the lid body, improving the blocking performance of high temperature hot air and steam. It has the effect of cooling the upper surface of the main body case.

and an upper body 13 molded from synthetic resin. A motor 14 is attached to the chassis 11, and the rotation of the motor 14 is controlled by a belt 16 placed around a small pulley 15 attached to a rotating shaft, and a large pulley 18 rotatably attached to a bearing 17 press-fitted into the chassis 11. power is transmitted,
Rotate the lower connector 19 fixed to the large pulley 18 by caulking or the like. There is a bread baking mold 21 inside the baking chamber 20 whose bottom part is fixed to the chassis 11.
This bread baking mold 21 is fixed in position by a bread baking mold stand 22. The bread baking mold 21 has an upper connector 22 that contacts the lower connector 19 to transmit rotation.
There is a kneading blade 23 that is detachably provided. On the side surface of the firing chamber 20, a heater 26 is attached by screwing a fixed insulator 24 and a fixing metal fitting 25, and a sensor 27 holding a thermistor inside is attached.
The ceiling frame 28 is attached to the upper part of the upper body 13 with screws or the like, and 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. The end surface of the ceiling frame 28 is brought into contact with the upper body 1 so that the hot air is as much as possible.
This prevents it from leaking in the direction of 3. Further, the lower part of the heat shield plate 29 is bent and placed between the chassis 11 and the firing chamber 20, and the firing chamber 20 and the chassis 11 are fixed by screwing together.

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

Furthermore, a firing lid 33 that forms a firing space above the firing chamber 20 is elastically attached to a lower lid 34 that constitutes a lid body, and this lower lid 34 is screwed to an upper lid 35 that constitutes a lid body. When the lid is closed, an inclined surface 34a formed on the inner circumference of the lower lid 34
is made to overlap the sloped surface of the rib 31. Note that the heat exhaust hole 32 is provided on the upper surface of the rib 31 located above this overlapped portion. A yeast container 36 is attached to the baking lid 33.
A valve 37 is attached to a hole in the yeast container 36 in the opening direction of the bread baking mold 21, and is attached to the valve 37 so as to be openable and closable.
A valve lever 38 is attached to one end of the valve 37, and a solenoid 39 is attached to the upper lid 35. A lever 40 is attached to the tip of the plunger of the solenoid 39.
This lever 40 is attached freely during operation.
The structure is such that the valve lever 38 comes into contact with the valve lever 38 to open the valve 37.

An exhaust guide 4 is provided between the upper lid 35 and the lower lid 34.
1 is fixed with a sandwich bench, and the exhaust guide 4
The lower lid 34 located below 1 is open. Further, the baking lid 33 is provided with a steam hole 42 .

Next, to explain the operation of this embodiment, ingredients such as water, flour, sugar, and salt are placed in the bread baking mold 21.
When the panel 43 having a circuit (not shown) is operated, the motor 14 is first rotated by the operation of the circuit, and the kneading blades 23 are rotated by power transmission to knead the material. When this kneading is finished, it enters the kneading mode, and when the set time until the kneading is finished, the solenoid 3
9 operates, valve 37 opens, and yeast 44 falls into bread 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 heater 26 is energized to bake the fermented bread 44, and when the process is finished, a buzzer sounds to notify the finished product.In order to automatically perform everything from kneading to baking, ingredients are added. You can make bread with just that.

Here, a rib 31 is provided on the top 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 communicating with the outside air is provided in this rib 31. 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 the upper body 31.
The high-temperature air and steam generated inside the baking chamber 20 when baking bread are much hotter than the outside air.
In addition, since the specific gravity is light, it rises, but in this case, due to the configuration in which the heat exhaust hole 32 is provided and the configuration in which the outer periphery of the rib 31 and the lower lid 34 of the lid body overlap,
Air from the bottom of the lower body 12 of the main case, which is formed by the drift effect of thermal convection air as the temperature rises in the firing chamber 20, flows upward through the heat exhaust hole 32 and forms an air wall. High-temperature air and steam generated from inside the firing chamber 20 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 body 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.

Furthermore, the outer periphery of the rib 31 and the lower lid 3 that constitutes the lid body.
Since the heat exhaust hole 32 is provided on the upper surface of the rib 31 located above the overlapped portion with the rib 31, even if water is accidentally spilled onto the product, the water will not be absorbed by the upper body 13 that constitutes the main case. The amount of air flowing into the lower body 12 is reduced, and since the air flowing out from the inside of the main body case consisting of the upper body 13 and the lower body 12 to the heat exhaust hole 32 has a flow velocity, the ventilating effect due to this flow velocity is reduced. In contrast, outside air can flow into the internal space of the upper lid 35 and lower lid 34 that constitute the lid body, further improving the blocking performance of high-temperature hot air and steam. It has the effect of cooling the upper surface.

Effects of the Invention As is clear from the description of the embodiments described above, according to the present invention, a lid that covers the upper part of the main body case in an openable and closable manner is attached to the outer periphery of a rib provided on the ceiling frame so as to protrude upward from the upper surface of the main body case. The lower lid of the body overlaps, and the upper surface of the rib located above this overlap part is provided with a heat exhaust hole that communicates with the outside air, so that the high temperature heat and steam generated inside the baking chamber during bread baking are removed from the lid. It is possible to prevent leakage from the gap between the body and the main body case, and also to prevent burns from coming into contact with these high-temperature hot air and steam, as well as preventing steam from condensing on the main body case and flowing down. Furthermore, it is possible to prevent the main body case from deforming due to hot air in the event of an abnormality.Moreover, by providing a heat exhaust hole on the top surface of the rib located above the overlap between the rib and the bottom cover. Even if water is accidentally spilled on top of the product, it is less likely that the water will flow into the main body case, and the ventilary effect due to the flow rate of air flowing from the inside of the main body case to the heat exhaust hole , it is possible to further improve the blocking performance of high-temperature hot air and steam.
