Abstract

PURPOSE: To turn off a switch when a bread case is taken out of the body even if dust has entered between the bread case and the actuation piece by providing an automatic baking device with the switch closing the power source circuit on charging the bread case, the actuation piece actuating the switch, and an elastic piece increasing the repulsive force of the switch. CONSTITUTION: An elastic piece 36 fixed to a switch 19 is positioned between the switch 19 and a switch lever 37 as an actuating piece. When wastes like bread crumbs have entered between the switch lever 37 and the bread case 8, bread can be baked in a usual way and then, the jamming wastes are pushed up by the repulsive force of the elastic piece 36, when the bread case 8 has been taken out of the oven chamber 6 and hence, the switch 19 is turned off.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an automatic bread maker that can produce freshly baked bread at a desired time by simply adding all ingredients, for example.

[Conventional technology]

Figure 5 is a sectional view showing a conventional automatic bread maker.
An oven chamber (6) equipped with a heater (4) and a heat shield plate (5) on the outer periphery is fixed. (8) is the oven chamber (6
A rectangular parallelepiped bread case is detachably attached inside ) and equipped with a kneading blade (7). , is decelerated and driven by a small pulley U.A is a handle attached to the top of the bread case (8), and a fixed stand fixed to the chassis (2) with supports configured on both sides of the αsFi oven chamber. I and the bread case (8) are held together by a connector rotatably installed at the bottom of the oven chamber (6).
It is linked to Ill.

The frame is a shaft for transmitting rotational force from the connector port 9 to the kneading blades ( ), and is rotatably supported by a transfer bearing Bad. A kneading blade (7) is detachably attached to the upper part of the shaft αη. (19 is a switch. When the bread case (8) is set, the switch lever ■, which is an operating piece, is suppressed by the bottom of the bread case (8) and turned on. It supports the tip of the CI'l+ heater (4). The insulator C that supports the rear end and the insulator C that supports the rear end are fixed to the oven chamber +61 with screws.The OFi thermoelectric sensor is pressed by a spring C4+ so that it comes into contact with the bread case (8). The fan is configured on the top of the motor (3) and is covered by a fan cover■.

It is configured to discharge heat from the motor (3) to the outside. @ is an upper lid that covers the upper part of the main body case (1), and consists of a reflector plate (■) that covers the upper part of the oven chamber (6) and an upper heat shield plate s2. ■ is a solenoid installed between the upper lid ■ and the heat-transmitting plate to open the bottom of the yeast container C311. A cover that covers the top of the Cl5ti yeast container 611, [Yes] is a control unit that controls bread baking, and (To) is a transmission unit that opens and closes the shutter (To) by the operation of solenoid ω with lever E linked to solenoid ω. It is.

Next, the operation will be explained. With the above configuration, put ingredients other than yeast (flour and water) into the bread case (8) and close the top lid +271'z. Next, open the cover of the yeast container, add yeast, and start operation.

Motor (3) rotates, mouth 11 small pulley, bell I-+9
1. The rotational force is transmitted to the kneading blades ( ) in the bread case (8) through the large pulley αrJf, and the material in the bread case (8) is kneaded.

During the process, the solenoid ■ operates to drop the yeast in the yeast container Gυ, which is further kneaded to make bread dough.

During the baking process, gas is vented, and finally the heater (4) is energized and the temperature is controlled by a temperature sensor to bake the bread. All of these are performed based on commands from the control unit □□□, and bread baking is completed.

[Problem that the invention seeks to solve]

The conventional switch +19Fi switch had a spring inside, which provided the repulsive force of the switch lever ■,
Because the repulsive force of the spring itself was small, it was not possible to obtain sufficient repetitive force. Therefore, if dirt gets stuck between the switch lever ■ and the bread case (8), the bread case (
8) Even if the switch was removed, the repulsion force was weak, so the switch 11g remained on due to dust getting stuck, and it was unable to demonstrate its performance as a safety switch. This invention was made to solve the above-mentioned problems, and aims to improve the repetitive force of the operating plate.

[Means to solve the problem]

The automatic bread maker according to the present invention includes a baking device including a reflector in the upper part of the oven chamber and a heater in the lower part, and a bread case provided in the oven chamber.

A kneading device provided at the bottom of the bread case and having kneading blades transmitted and driven by a motor, a switch that closes the power circuit when the bread case is attached, an operating piece that operates the switch, and a kneading device that controls the repulsive force of the switch. and an increasing elastic piece, the elastic piece being provided between the switch and the operating piece.

[Effect]

In the automatic bread maker according to the present invention, the repulsive force of the switch is increased by the elastic piece provided between the switch and the operating piece.

[Embodiments of the invention]

Hereinafter, parts of an embodiment of the present invention that are different from the conventional automatic bread maker shown in FIG. 4 will be explained.

(to) is an elastic piece fixed to the switch fi9, and is located between the switch σ9 and the switch lever Gn, which is the operating piece. In the automatic bread maker configured as described above, when dust such as bread crumbs enters between the switch lever (support) and the bread case (8).

After normal use, when the bread is finished, when the bread case (8) is removed from the oven chamber (6), the repulsive force of the elastic piece 1 pushes up the clogged garbage, so switch αg.
is turned off.

〔Effect of the invention〕

As described above, according to the present invention, elasticity is provided between the switch and the operating piece, so even if dirt enters between the bread case and the operating piece, the repulsive force of the operating piece increases. For,
You can push it up and take out the entire bread case (8). The viewing circuit is open and safety is maintained. We can provide highly reliable products.
