The rotational driving force of the electric motor 102 is transmitted to the driving pulley 106, the belt 107, and the driven pulley 108, and the kneading provided at the inner bottom portion of the bread container 110 for storing the bread material such as flour, water, yeast, etc. in the baking chamber 109. The blade 111 is rotationally driven to knead the bread material. Reference numeral 112 denotes a lid that covers the upper portion of the baking chamber 109 so as to be freely opened and closed. Reference numeral 113 denotes a heater that is controlled by the operation substrate 104 and controls the temperature of the baking chamber 109 in the same manner as the electric motor 102.
[0004]
By controlling the electric motor 102 and the heater 113 according to the command of the control means, bread making processes such as a bread material kneading process, a kneading process, a degassing process, and a bread baking process are sequentially performed to produce bread. In addition, the terminal portion 114 of the heater 113 protrudes from the baking chamber 109 to the lower part inside the main body. Further, the separate substrate 105 is disposed horizontally in order to avoid the terminal portion 114 at the bottom of the main body, and is electrically connected to the operation substrate 104 by the cable 115.

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0016]
1 to 4, an electric motor 2 is built in the main body 1, and the electric motor 2 is arranged at the lower part of the main body 1 and is electrically connected to the operation board 4 according to an instruction from the operation board 4 built in the operation unit 3. The power supply board 5 is rotated and stopped by switching. The rotational driving force of the electric motor 2 is transmitted to the driving pulley 6, the belt 7 and the driven pulley 8, and the kneading provided at the inner bottom of the bread container 10 for storing the bread material such as flour, water and yeast in the baking chamber 9. The blade 11 is rotationally driven to knead the bread material. Reference numeral 12 denotes a lid that covers the upper portion of the baking chamber 9 so as to be freely opened and closed. Reference numeral 13 denotes a heater that is controlled by the operation substrate 4 and controls the temperature of the baking chamber 9 in the same manner as the electric motor 2. By controlling the electric motor 2 and the heater 13 according to the command of the control means, bread making processes such as a bread material kneading process, a kneading process, a degassing process, and a bread baking process are sequentially performed to make bread. Further, the terminal portion 14 of the heater 13 protruded from the firing chamber 9 toward the lower part inside the main body. The power supply board 5 is electrically connected to the operation board 4 by a cable 15.
[0017]
The main body 1 is mainly composed of a body 16 and an upper frame 17 constituting the upper part, and the power supply substrate 5 is disposed between the outer surface of the baking chamber 9 and the inner surface of the body 16 and is attached to the upper frame 17 via a holder 20. ing. Further, the operation unit 18 incorporating the operation board 4 is attached so as to cover the power supply board 5 from above. As a result, since the operation board 4 and the power supply board 5 are located close to each other, the wiring work by the cable 15 is reliable and easy, and the assemblability is remarkably improved. Moreover, since the power supply board | substrate 5 can be set | placed vertically avoiding the heater connection part 14, a dead space can be decreased and a product can be designed compactly.
[0018]
Further, a vent hole 19 is provided on the side surface of the body 16 at substantially the same height as the power supply board 5, and a wall 21 is provided at a position opposed to the vent hole 19 integrally with the holder 20 to which the power supply board 5 is attached. Yes. As a result, the heat from the heater 13 during the baking of the pan staying in the main body 1 can be discharged from the vent hole 19, and the electronic components on the operation board 4 and the power supply board 5 can be prevented from being overheated. When liquid such as water is applied from the outside due to the shielding by the wall 21, water is applied to the charging parts such as the electronic components on the board and the heater terminal part 14 to prevent the user from getting an electric shock and to the deep part inside the main body. It can prevent intrusion. In addition, it is possible to prevent the components, electric wires, and the like in the main body from being unsightly visible from the outside due to the shielding by the wall 21.
[0019]
The wall 21 provided integrally with the holder 20 is provided with a lattice shape 22. As a result, when a liquid such as water is applied from the outside, the scattering of water can be mitigated by the resistance by the lattice, and the penetration into the deep part in the main body can be more reliably prevented. The same effect can be obtained even if the lattice shape 22 is a convex or concave dimple shape. Moreover, since the wall 21 is curved, the effect can be further improved.
[0020]
Further, the wall 21 provided integrally with the holder 20 is inclined in a direction away from the heater terminal portion 14.
[0021]
As a result, when a liquid such as water is applied from the outside, the direction in which the water scatters can be changed, and the penetration of water into the deep part in the main body where the charging unit such as the heater terminal 14 is located can be more reliably prevented.
[0022]
The holder 20 has an upper portion coupled to the upper frame 17 and has a boss 23 extended on the baking chamber 9 side. Thereby, when inserting the terminal or cable 15 for electric wiring on the power supply board 5 at the time of assembly, or when a strong impact is applied to the main body, a load is applied to the power supply board 5 and the holder 20 toward the baking chamber 9 side. In this case, the holder 20 can be supported by the baking chamber 9, and damage to the power supply substrate 5 and the holder 20 can be prevented.
[0023]
The holder 20 is made of a thermoplastic resin, and a gap is provided between the boss 23 and the baking chamber. Thereby, it can prevent that the boss | hub front-end | tip part becomes high temperature and melt | dissolves with the heat | fever of the baking store | warehouse | chamber 9 which becomes high temperature from the heat | fever of the heater 13 at the time of bread baking.
[0024]
Three bosses 23 are provided at different heights in the product height direction. Thereby, the holder 20 can be supported by the firing chamber 9 when the power source substrate 5 and the holder 20 are more reliably loaded on the firing chamber side.
[0025]
Further, the holder 20 is provided with four ribs on the inner wall side of the body 16 integrally with the holder so as to be higher than the electronic components on the power supply board 5. As a result, when the body 16 is deformed inward due to an external load or impact, the load is received by the rib 24, so that no force is directly applied to the electronic components on the power supply substrate 5, thereby preventing the substrate from being damaged. Can do. In addition, since the ribs are provided at four locations, upper, lower, left and right, it is possible to stably receive deformation of the body and prevent damage to the substrate more reliably.
[0026]
A gap is provided between the rib 24 and the inner wall surface of the body 16. As a result, it is possible to prevent the rib and the body from rubbing due to vibration generated when the bread material is kneaded, and to prevent generation of sound and damage to the rib due to vibration.
[0027]
Further, since the body 16 is white and the wall 21 is also white, the air holes are not conspicuous, and the appearance quality and design of the product are not impaired.
[0028]
【The invention's effect】
As described above, according to the present invention, the heat staying in the main body can be discharged from the hole, and the penetration of water or the like from the outside into the deep part of the main body can be prevented by shielding with the wall. Further, it is possible to prevent the inside of the main body from being visible from the outside due to the shielding by the wall. Further, the substrate can be placed vertically in the upper part of the body while dissipating heat, and a compact product can be realized.
