Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bread maker that automatically performs a series of steps of kneading, fermenting, and baking by charging bread ingredients and bake bread at a predetermined time. It is.

2. Description of the Related Art In general, bread making methods include the straight-cooking method and the medium noodle method. A bread maker that automatically kneads, pastes, ferments, and bake using the medium noodle method is shown in FIGS. The structure was as shown in FIG.

That is, a frame 2 is provided inside the main body 1, and the frame 2 has a firing chamber 5 in which a motor 3 and a heating means 4 are mounted.
Is fixed, and a baking case 7 having kneading means 6 is removably mounted in the baking chamber 5. Further, the kneading means 6 has a small pulley 8, a belt 9, a large pulley
10, which are transmitted via connectors 11 and 12. Reference numeral 13 denotes a lid for covering the firing chamber 5, and a central portion of the lid 13 is provided with an yeast container 14 for storing dry yeast. An openable / closable valve 15 is attached to the lower surface of the yeast container 14. By opening the valve 15, dry yeast is put into the baking case 7. 16 is a solenoid, lever
The valve 15 is opened and closed via 17. 18 is a valve support for holding the valve 15, 19 is an inner lid, and 20 is a circuit for timer, temperature and power control. With such a configuration, materials such as flour and water are charged into the baking case 7, and dry yeast is charged into the yeast container 14. When the switch is turned on, each process is automatically performed and bread is baked at a predetermined time. It is.

Problems to be Solved by the Invention The process of the middle noodle method is pre-kneading → sleeping → yeast feeding → main kneading → fermentation → baking, but in order to make finer soft bread, pre-kneading → sleeping → yeast Input →
There is a method called a medium seed method having a process of middle kneading → sleep → yeast feeding → main kneading → fermentation → baking. in this case,
It is necessary to divide the yeast into two parts, and when the first amount of dry yeast falls into the predetermined amount of dry yeast falling from the yeast container 14, the yeast container 14 is closed with the valve 15. There is a need. At this time, in the conventional configuration, the valve 15 repels the dry yeast, which causes a problem that the dry yeast scatters and protrudes from the firing case 7.

The present invention solves such a conventional problem.
It is an object of the present invention to provide a bread maker capable of surely feeding a dry yeast into a baking case without splashing dry yeast when a predetermined amount of yeast falls and a valve closes during the first yeast feeding. Is what you do.

Means for Solving the Problems In order to solve the above problems, the present invention provides a valve for opening and closing the lower surface opening of the yeast container incorporated in the lid to drop the yeast into the firing case, and around the valve. Are arranged around the wall.

Operation In the above configuration, when the first yeast input, when the dry yeast falling from the yeast container reaches a predetermined amount, the valve blocks the lower end opening of the yeast container and closes.
At this moment, the dry yeast scatters around the valve. However, in the present invention, since the wall surrounding the periphery of the valve is provided,
The scattered dry yeast is blocked by this wall and does not scatter outside the wall, and as a result, the dry yeast falls directly below and is surely put into the firing case.

Embodiment An embodiment of the present invention will be described below with reference to FIGS.

In FIGS. 1 to 4, a firing case 23 detachably provided in a firing chamber 22 having a heating means 21 constituted by an electric heater is formed in a bottomed cylindrical shape having an open upper side. A kneading means 24 made up of blades is provided at the inner bottom of 23. The kneading means 24 is linked to a drive source via couplings 25 and 26. 27 is a temperature sensor for detecting the temperature of the firing case 23 and controlling the heating means 21 and the like; 28 is a lid for opening and closing the upper opening of the firing chamber 22;
It has 29. A yeast container 30 is mounted in a space between the lid 28 and the inner lid 29. This yeast container
An opening 31 is provided in the center of the lower surface of 30 and this opening
A valve support 33 that supports a valve 32 that closes the opening 31 is attached around the periphery of the valve 31. The valve support 33 has a wall 34 formed around the periphery of the valve 32, and the valve support 33 is sandwiched between the yeast container 30 and the inner lid 29. Also,
A solenoid 35 drives the valve 32. The solenoid 35 drives the valve 32 via a lever 36. Reference numeral 37 denotes a spring for returning the lever 36, and reference numeral 38 denotes a spring for returning the valve 32. A control circuit 39 controls the heating means 21, the kneading means 24, the solenoid 35 and the like.

In the above configuration, all steps of bread production will be briefly described. First, bread materials such as flour, salt, sugar, butter, and water are charged into the baking case 23, and dry yeast is also charged into the yeast container 30. Then, when the operation is started, the above-mentioned bread ingredients are kneaded, and after a certain period of time, a predetermined amount of dry yeast is added, and the process for aged is started. After a certain period of time,
The remaining dry yeast is charged and the process proceeds to the main kneading process, where the primary, secondary and tertiary fermentation is performed. In the process, degassing for kneading is performed in a certain cycle, the process proceeds to the shaping fermentation, and then proceeds to the firing process.

Next, the operation of the yeast dosing mechanism of the present invention in the above bread manufacturing process will be described. First, when a predetermined time elapses after the start of operation, the first yeast injection is performed. In this operation, as shown in FIG. 3, the shaft 35a of the solenoid 35 is pulled in the direction of arrow A by the magnetic force, and the lever 36 attached to the end of the shaft 35a of the solenoid 35 rotates in the direction of arrow B. Push the valve shaft 32a to open the valve 32. As a result, the dry yeast in the yeast container 30 falls into the baking case 23. When a predetermined amount of dry yeast falls, the magnetic force of the solenoid 35 is cut off, so that the force of the return spring 37 of the lever 36 and the force of the return spring 38 of the valve 32 cause the valve 32 to return.
Closes the opening 31 of the yeast container 30. At this time, the valve 32 blocks the dry yeast flowing from the opening 31 of the yeast container 30 on the way, so that upward and lateral forces are applied to the falling dry yeast. As a result, the dry yeast scatters around the valve 32. However, in one embodiment of the present invention, since the wall 34 is formed on the valve support 33 so as to surround the periphery of the valve 32, the dry yeast scattered around the valve 32 is blocked by the wall 34. As a result, the dry yeast does not scatter outside the wall 34. Therefore, the dry yeast is reliably injected into the baking case 23 by a predetermined amount without protruding from the baking case 23 located below the yeast container 30. Note that the first dry yeast feeding amount can be set based on the opening time of the valve 32 (the energizing time of the solenoid 35) or the like.

In the above embodiment, the valve support 33 is formed with the wall 34 for preventing the yeast from being scattered when the valve 32 is closed during the dry yeast introduction, but the support 33 is surrounded by the inner lid 29. Even if the ring-shaped wall 34 is formed as described above, the same effect can be obtained.

According to the present invention, as apparent from the description of the above embodiment, a valve for opening and closing the lower opening of the yeast container for storing the yeast and dropping the yeast into the baking case is provided. With the surrounding wall, even if the valve is closed during the yeast injection, the presence of the wall prevents the yeast from scattering around the valve, and as a result, the yeast is placed under the yeast container. Can be surely put into the firing case located at the position. As a result, the dry yeast can be put in several times, so that finer and softer bread can be made.
