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 When baking bread at home, generally a kneader, a fermenter,
Although equipment such as a stick and an oven is used, it is difficult to control the temperature and time, and it requires considerable skill. In order to solve these problems, there has been proposed a bread maker capable of storing the kneading, fermenting, and oven functions as shown in FIGS. 4 and 5 in one device and baking bread at a predetermined time. I have.

4 and 5, a frame 2 is provided inside a main body 1, and a motor 3 is provided on the frame 2.
The firing chamber 5 to which the heater 4 is mounted is fixed, and the firing chamber 5
Inside, a firing case 7 having kneading blades 6 is detachably mounted. The rotating force of the motor 3 is applied to the kneading blade 6 by the small pulley 8, the belt 9, the large pulley 10, the couplings 11, 1 and 2.
Conveyed by two. Reference numeral 13 denotes an outer lid that covers the upper opening of the firing chamber 5, and 14 denotes an inner lid that surrounds the inside of the outer lid 13. Further, an inner lid 15 is provided inside the inner lid 14, and a yeast container 16 is disposed at a central portion of the inner lid 15. Reference numeral 17 denotes a control circuit for adjusting time, temperature, and power.

With such a configuration, bread ingredients are put into the baking case 7,
When the timer is set, the operation starts at a predetermined time, and the kneading, fermentation, and baking steps are automatically performed, and the bread is baked at a predetermined time.

Problems to be Solved by the Invention In the above-mentioned conventional bread making machine, since the upper part of the baking chamber 5 has a high temperature exceeding 200 ° C. in the baking process, the lid covering the upper opening of the baking chamber 5 is covered with the outer lid 13 and the inner lid 13. There is a problem that the lid 14 and the inner lid 15 must be formed in a triple structure. This is for the following reason.

That is, since the outer lid 13 becomes an outer shell, the temperature must be lowered to a temperature that is not hot even if touched by a hand. Therefore,
The outer lid 13 cannot be formed of metal, and must necessarily use resin. In addition, the inner lid 14 must be provided inside the outer lid 13 to provide a heat insulating layer for air. However, in order to maintain strength, the inner lid 14 and the outer lid 13 must be locked with a screw or the like.However, if the outer lid 13 and the inner lid 14 are directly locked with a screw, the temperature of the threaded portion becomes lower. Since it rises, the resin of the outer lid 13 must use a super heat-resistant resin, which is very expensive. Therefore, in order to lower the temperature of the inner lid 14, the inner lid 15 must be further disposed between the inner lid 14 and the firing chamber 5. Further, since the yeast container 16 is formed of a super heat-resistant resin and is locked to the inner lid 15, it has a very complicated structure.

An object of the present invention is to provide a bread maker which solves such a conventional problem.

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention locks a yeast container formed of a super heat-resistant resin with a screw at a central portion inside an outer lid covering an upper opening of a firing chamber. Further, an inner lid made of sheet metal is locked to the yeast container with a screw.

Action According to the above configuration, the inner lid, which is heated to a high temperature, is locked with a screw to the yeast container molded of super heat-resistant resin, so that the screw locking portion of the yeast container is melted even when the screw is heated to a high temperature, It is not deformed, and the yeast container is screwed to the outer lid, but this screw is separated from the hot inner lid, and also provides a layer of air insulation between the outer lid and the inner lid. Since it is located, even if the outer lid is molded with a general-purpose resin, the screw locking portion of the outer lid does not melt or deform. As a result, a very simple lid structure is obtained, and the lid can be manufactured at low cost.

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

In the figure, a frame 22 is provided inside a main body 21, and a motor 23 and a heating means 24 composed of a heater are mounted on the frame 22, and a firing chamber 25 is fixed, and the firing chamber 25 includes vanes. A firing case 27 having kneading means 26 is detachably mounted. The rotation force of the motor 23 is applied to the kneading blades 26 by a small pulley 28, a belt 29, a large pulley 30, and a coupling 3.
Communicated by 1,32. An outer lid 33 covers the upper opening of the firing chamber 25. The outer lid 33 is formed of a general-purpose resin. 34
Is an inner lid surrounding the inside of the outer lid 33. The outer lid 33
A yeast container 35 formed of a super heat-resistant resin is fixed at the center with screws 36, and the inner lid 34 is fixed to the yeast container 35 with screws 37. With such a configuration, the inner lid 34 is fixed to the outer lid 33 via the yeast container 35.

Next, the operation of the configuration of the above embodiment will be described. First, bread materials such as flour, salt, sugar, butter, and water are put into the baking case 27. When the operation is started, the bread ingredients are kneaded, and after a certain period of time, dry yeast is mixed and further kneaded. Next, it shifts to a fermentation process. When shifting to this fermentation step, degassing for kneading is performed in a certain cycle, and primary, secondary, tertiary,
It proceeds with the shaping fermentation, and then moves on to the baking step. In this firing step, the upper central portion in the firing chamber 25 has a temperature of 200 ° C. or higher, so that the temperature of the inner lid 34 and the screws 37 fixing the inner lid 34 also exceed 200 ° C. This temperature is the temperature at which melting and deformation occur in general-purpose resin, but since the screw 37 is locked to the yeast container 35 formed of super heat resistant resin, the screw part of the yeast container 35 may melt and deform. There is no. Also, a screw that locks the yeast container 35 to the outer lid 33
36 is separated from the hot inner lid 34, and the outer lid 33 and the inner lid 34
The temperature is lowered to a temperature that can be sufficiently endured by a general-purpose resin. Therefore, the locking portion of the screw 36 of the outer lid 33 does not melt and deform.

According to the present invention, as is apparent from the description of the above embodiment, the inner central portion of the outer lid that covers the upper opening of the firing chamber includes:
Lock the yeast container molded with super heat resistant resin with screws,
Further, since the inner lid made of sheet metal is screwed to the yeast container with a screw, a middle lid is further provided between the inner lid and the baking chamber as in the conventional case, and the lid is made into a triple structure, and the temperature of the outer lid is increased. Therefore, it is not necessary to lower the size, and it can be manufactured at a low cost with a simple structure.
