Abstract

PURPOSE:To rotate a second shaft for turning a turntable and a first shaft for turning blades in a vessel each at a speed suited to their specific uses by setting the two shafts coaxially and providing each shaft with a separate drive device. CONSTITUTION:In the drive unit 8, a turntable 20 for a mount base and a kneading pan 21 as a vessel are detachably mounted. When high frequency heating or heater-heating is applied, a rotary shaft 23 is mounted in a turntable- kneader drive unit 8 by fitting a joining protrusion 24 in the shaft 23 into a groove in the top of a second shaft 18. When dough is kneaded for baking, the joint 30 of a rotary shaft 28 is joined with the joint 13 of a first shaft 12 by fitting protrusions on the top of a bearing case 11 into corresponding holes 31 in a bearing case 25 so that a kneading pan 21 can be mounted in place in the heating chamber 2. The first shaft 12 and the second shaft 18 do not act unfavorably upon each other's performance.

Description

[Detailed description of the invention] g) Industrial application field The present invention relates to a heating cooker.

(b) Conventional Technical Utility Model Publication No. 56-32174 discloses a cooking device in which a kneading container with keyaki wings is detachably installed in a heating chamber for kneading and roasting bread dough. . However, in this structure, the keyane blades are rotationally driven by the blower motor, which requires a large number of pulleys to transmit power from the motor to the keyane blades, making the structure complex and difficult to assemble. It was something.

On the other hand, some heating cookers such as microwave ovens are equipped with a turntable on the bottom wall of the heating chamber. Therefore, it is conceivable to use the drive source of the power-bow turntable as the drive source of the kneading blades, but while the rotation speed normally required for a turntable is about 5 rpm, the rotation speed of the kneading blades is 2 rpm.
It is desirable that the speed be approximately 0.00 rpm, and such dual use has been difficult.

(c) Problems to be Solved by the Invention The object of the present invention is to provide a heating cooker that is capable of kneading and roasting bread dough and has a simple structure.

)! ! A heating cooker of the present invention includes a heating chamber, a heating source, first and second driving sources, and a heating chamber provided on a bottom wall of the heating chamber,
A first shaft rotationally driven by a drive source, and the! a second shaft provided coaxially with the a1 axis and rotationally driven by the second drive source; a container removably attached to the bottom wall of the heating chamber; and a second shaft rotatably provided at the bottom of the container. The container body is characterized by comprising a container body made of a blade body which is rotationally driven by the first shaft when mounted, and a stand which is rotated and driven by being removably engaged with the second shaft.

(E) Effect When the container body is used, the blade body is driven by the first Fi driving source, and when the mounting table is used, the @ placing table is driven by the second driving source.

(f) Example An embodiment of the present invention will be described in detail below based on the drawings.

+11 is the main body of the open range, (2) is a heating chamber formed within the main body, and (3) is a door that opens and closes the opening of the heating chamber. f4] f51 are heaters provided at the upper and lower parts of the heating chamber (2), respectively, and (6) is a magnetron that supplies high frequency waves into the heating chamber (2) via the waveguide (7). A drive unit (8) for rotationally driving a turntable and baking blades of a bread case, which will be described later, is provided on the bottom wall (2&) of the heating chamber (2). Here, (9) is the bottom wall (2
The recess in a) (1 (fl) is a bearing fixed through a bearing case (II), Q is a hollow cylindrical first shaft rotatably supported by the bearing, and G is the upper end of the fjltl shaft. A joint is attached to the joint, Q4aaE is a pulley attached to the lower end of the first axis Qη, and am is a motor as a first drive source that rotationally drives the first axis 0η via a belt (Iφ) and a pulley aη.

In addition, Ol is the first shaft (provided coaxially with the first shaft in the hollow part of one shaft), and Al is the second shaft as a second drive source that directly rotationally drives the second shaft. It is a torque motor, and the structure is such that the IEI shaft (I'A) and the second shaft 6 do not interfere with each other's rotation.

The drive unit (8) has a turntable holder as a mounting base and a bread case as a container body which are detachable, and these can be selectively attached.

The turntable consists of a placing part and a hollow rotating shaft attached to the central part of the lower surface of the placing part by spot welding.

When performing normal high-frequency heating or heater heating with this open range, as shown in Figure 2, the engagement protrusion F241 in the rotating shaft (to) should be connected to the second shaft (I, the retaining groove C on the top surface). figure)
to engage the turntable with the drive unit (8) K
Finished 11th. Then, if the turntable holder is rotated at a low speed (for example, about 5 rpm) by a torque motor during heating, it will be on the turntable! It is possible to prevent uneven heating of the object to be heated by the IC device.

A pan case (21) Fi, a container having a bearing case on the lower surface and attached to the bottom wall (2&) of the heating chamber (2) via the bearing case (2) and the round; bearing(
A rotating shaft (
(c), a spring impeller as a blade attached to the upper end of the rotating shaft and located inside the container, and engaged with the joint 01 when attached to the bottom wall (2a) of the container; and a joint that transmits the rotational force of the first shaft to the rotating shaft (c).

Therefore, when roasting bread dough using this open range, the engagement protrusion C (not shown) formed on the upper part of the bearing case (11) is inserted into the retaining hole formed in the bearing case (A). (31) Connect the joint (end) of the rotating shaft (c) to the joint Ql of the 1lEi shaft 6m while engaging K, and install the bread case Q1) into the heating chamber (2).

Due to the engagement between the engagement protrusion and the retention hole (2), the container (26)
is fixed in the heating chamber (21) without undesired rotation.

Then, by putting bread ingredients such as flour and yeast into the container (26) and rotating the cage impeller at high speed (for example, zoorpms degrees) by a motor, the dough can be kneaded. Subsequently, when the heater 141 [fi] is energized, the bread can be roasted.

The heater (41+51% magnetron (6), motor 019) of this open range is electronically controlled by a control circuit such as a microcomputer (not shown), and automatically performs everything from kneading dough to roasting in good condition. can be done.

According to the above configuration, the second axis (Is) for driving the turntable and the l@1 axis for driving the kneading blades (A) of the bread case (21) are provided coaxially on the 0 axis, and Since the driving source is provided, the first axis θ2 and the second axis do not adversely affect each other's operations, and each axis can be driven to rotate at a speed suitable for each purpose.

Although this embodiment has been described with reference to the case where bread dough is pounded, the present invention can be used in various other ways, such as when making rice cakes.

(G) Effects of the Invention According to the present invention, the second shaft that drives the @ placing stand and the first shaft that drives the blade of the container body are provided coaxially, and a drive source is provided for each of them. Each shaft does not affect the operation of the other, and each shaft can be driven to rotate at a speed suitable for each purpose.

Furthermore, since the structure is simple, even if two drive sources are provided, it can be manufactured at relatively low cost.
