Description

[Detailed description of the invention] "Industrial application field" This invention involves putting flour, water, baking powder, etc. into a bread baking case, kneading the flour, etc. in the bread baking case, and performing primary fermentation and secondary fermentation. The present invention relates to a blower device for a bread maker that is used to bake bread after baking.

"Prior Art" Conventionally, after kneading bread ingredients, primary fermentation and secondary fermentation of the dough was carried out at natural temperature in an oven chamber.

``Problems that the invention seeks to solve'' In the conventional technology, the temperature inside the oven chamber is affected by the outside temperature of the baking oven, making it impossible to obtain a constant fermentation environment and resulting in poor fermentation of the dough. It was hot. Therefore, we developed a technology to send hot or cold air into the bread baking case inside the oven, but it is necessary to have the air exhaust port facing above the baking case. There was a problem in that the duct that was formed made it extremely difficult to take out the bread.

``Means for Solving the Problems'' However, the present invention includes a bread baking case in which bread ingredients are fed, kneaded, fermented, and baked.
In a device in which the baking case is removably installed in the oven chamber on the upper part of the baking oven body, the top cover of which is installed so that the top lid can be opened and closed, the outside air intake passage is equipped with a blower fan on the intake side and a heating heater on the exhaust side. A duct is formed in the baking oven body and has an air exhaust port facing above the baking case to send air from the fan, and the duct is divided at a joining position between the baking oven body and the top cover. They are formed and connected in a row so that they can swing freely.

"Function" Therefore, according to this invention, by moving the exhaust port of the duct to a ventilation position overlapping with the baking case in a plan view during bread making, hot or cold air can be sent only into the baking case, and the temperature around the dough can be maintained at the optimum fermentation temperature more efficiently than by adjusting the temperature of the entire oven chamber, and the ventilation fan and heater can be made smaller than before.
By making the structure compact and reducing costs, a good fermentation environment can be created, and by moving the exhaust port of the duct to a storage position above the baking case where it does not overlap in a plan view when removing bread, the duct is prevented from becoming an obstacle when removing and installing the baking case (removing bread) or cleaning the oven interior, and the installation and removal of the baking case and cleaning of the oven interior can be performed smoothly.

Then, the heater 35 is operated as appropriate to send hot air or cold air into the baking case 16, and the temperature inside the case 16 is maintained at the optimum fermentation temperature of about 28 degrees to carry out primary fermentation and secondary fermentation, respectively. Later, the heater 15 is activated to bake bread in the oven chamber A, and when baking the bread, this internal temperature is measured by the thermistor 28.
When the internal temperature rises above the setting and the bread is baked, the heater 15 is switched off based on the thermistor 28 output, and the blower fan 3 is turned off.
1 blows cold air to cool the baked bread to the same level as the outside temperature, completing the bread production.

After baking the bread, open the top lid 5, move the guide duct 36b from the air blowing position to the storage position, remove the baking case 16 from the inner case 11 and take it out of the baking oven body 2, and remove the bread from the baking case 16. It is something to take out.

"Effects of the Invention" As is clear from the above embodiments, the present invention includes a bread baking case 16 in which bread ingredients are fed, kneaded, fermented, and baked, and a baking oven main body 2 in which a top lid 5 is installed so that it can be opened and closed. In an apparatus in which the baking case 16 is removably installed in the upper oven chamber A, the outside air intake air passage 30 is connected to the baking oven body 2, and has a blower fan 33 on the intake side and a heating heater 35 on the exhaust side. In addition, the air exhaust port 38 is made to face above the firing case 16, and the fan 3 is connected to the firing case 16.
A duct 36 is provided for blowing air from the oven 3, and the duct 36 is divided into parts at the joining position of the baking oven body 2 and the upper lid 5, and the duct 36 is connected so as to be swingable. Case 1 for firing 38 parts of the wind opening
By moving the air blowing position to the position that overlaps the air blowing position 6 in plan view, hot air or cold air can be sent only into the baking case 16, which is more efficient than adjusting the temperature of the entire oven chamber A. In addition to being able to maintain the temperature at the optimum temperature for fermentation, the blower fan 33 and heating heater 35 can be made smaller than before, making the structure more compact and reducing costs, creating a favorable fermentation environment. By moving the air exhaust port 38 of the duct 36b to a storage position above the baking case 16 where it does not overlap in plan view when taking out the bread, the duct 36b can be used to remove the baking case 16 (bread removal) and attach it, or to clean the oven chamber A. This has practical effects such as preventing the baking case 16 from becoming a hindrance, and making it possible to smoothly attach and detach the baking case 16 and to clean the inside of the oven chamber A.
