Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an additive dropping device for an automatic bread maker, in which bread is baked at a desired time only by setting a predetermined material.

2. Description of the Related Art Conventionally, as an additive for an automatic bread maker of this kind (among various types, hereafter described as yeast), a dropping device configured as shown in FIGS. 3 and 4, for example, is used. Are known.

Referring to the drawing, reference numeral 1 denotes a separation wall located above a kneading container (not shown), and the separation wall 1 communicates with a hole 1a of the separation wall 1 to drop yeast toward the kneading container. A yeast container 3 having a lower opening 2 is provided. Reference numeral 5 denotes an on-off valve which engages with a lever 4 of a driving device (not shown) such as a solenoid to open and close the hole 1a of the separation wall 1. The on-off valve 5 is associated with a flat valve portion 5a and the driving device. A rotary shaft 5b rotatably supporting the joint valve portion 5a,
Due to the tension coil spring 6, the valve portion 5a is always in the hole of the separation wall 1.
It is urged to abut 1a.

However, in such a configuration, after the valve unit 5a is opened by the operation of the driving device and the yeast is dropped, when the driving device is released, the valve unit 5a is separated by the tension coil spring 6 so that the separation wall is separated. The driver hit the No. 1 and produced a loud tapping noise, which hindered sleep during driving at night.

In addition, there is a method of baking the yeast which is widely and generally performed at present, in which yeast is divided into two portions, and in such a configuration, the opening time of the valve portion 5a, that is, the driving device Even if the operation time is controlled, the amount of yeast dropped will be inaccurate (large variation) and the valve 5a
Causes the yeast to scatter widely and protrude out of the kneading container, or close the valve 5a while the yeast is falling.
Yeast gets caught between the container and the separating wall 1, and the moisture (moisture) in the kneading container enters the yeast container 3 to fix the yeast, and then the yeast does not drop and bread cannot be made at all. There was a problem.

The present invention solves such a problem, and suppresses the sound at the time of dropping additives such as yeast, and eliminates biting and scattering of additives so that the additives can always be dropped separately by a fixed amount. The purpose is to do so.

Means for Solving the Problems In order to solve this problem, the present invention relates to a kneading container provided in a cooking chamber and having a kneading blade transmitted and driven by a motor at an inner bottom portion, and a kneading container positioned above the kneading container. An additive container having an opening at the lower end for dropping the additive toward the kneading container, and a drop hole at a position overlapping the opening below the additive container and slidably supported. Gate valve, a driving device for operating the gate valve, and a separation wall having a hole at a position below the gate valve and offset from the opening, and the gate valve is slid by the driving device. Thus, the discharge hole of the gate valve is aligned with the hole of the separation wall, and the additive in the discharge hole is dropped into the mixing container.

Function With this configuration, when the additive such as yeast is dropped, the valve is opened and closed by sliding motion compared to the conventional example in which the valve is rotated and hit against the separation wall, so that the generated sound can be suppressed small. Is capable of constantly dropping a constant volume without the occurrence of biting or scattering of additives.
