Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric cooking device such as a food processor, and is intended to perform various kinds of cooking with one device.

Traditionally, the functions of cooking appliances include those with relatively high rotation speeds of 1000 rpm to 3000 rpm, such as food processors, and low speed ones of 20 Orpm to 500 rpm, such as bread kneaders and whisks. It is broadly divided into

There was a big problem in obtaining these two functions in one device.

In other words, if you replace multiple blades or cutters in one container and use them at different speeds, if you accidentally use the blades for low speed at high speed, the blades will fly off due to the high load of ingredients such as bread kneading. It was extremely dangerous.

The present invention solves this problem, and is designed for low speed and
The rotation direction is changed between high-speed and high-speed applications, and attachments can be selectively equipped to suit each rotation direction.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 houses a power unit consisting of a heater 2 whose rotating direction can be changed as appropriate in the main body of the cooking device, and a speed reduction mechanism 3 that includes a clutch and gears.

Reference numeral 4 denotes a power section side connector attached to an output shaft 5 protruding from the main body 1, and a plurality of retaining sections 6 are provided around the connector.

Reference numeral 7 denotes a connector on the container side that engages with the connector 4, and is provided with a plurality of retaining portions 8 that fit between the retaining portions 6.

Reference numeral 9 denotes a container removably placed on the main body 1, and a main shaft 10 is rotatably supported at the center bottom of the container through a meckle 11 passing through the inside and outside.

The above-mentioned connector 7 is attached to the end of the main shaft 10 outside the container 9.

Further, an attachment 12 such as a cutter member having knife-like cutters 11 in two stages, upper and lower, is detachably attached to the end of the main shaft 10 inside the container 9.

13 is a container lid that covers the opening of the container 9.

Reference numeral 14 denotes an attachment having blades 15 having a framework structure made of wire rods, and in this example, one for foaming is shown.

This attachment 14 can be installed on the main shaft 10 selectively with the attachment 12.

Reference numeral 16 denotes a protrusion for transmitting power provided at a portion of the main shaft 10 that fits with the attachments 12 and 14, and is provided perpendicular to the main shaft 10.

Reference numeral 17 denotes an engagement member of an attachment that engages with the protrusion 16, and is provided integrally with the attachment members 1-12 and 14, respectively.

The engaging member 17 has one side with an inclined surface 18 that pushes up the attachment when the projection 16 rotates in one direction, and the other side with a transmission surface that acts in the direction of fixing the attachment to the main shaft 10 when the projection 16 rotates in the other direction. It is set as side 19.

The inclined surface 18 and the transmission surface 19 of the retaining member 17 are oriented in opposite directions on the attachments 12 and 14.

In the above configuration, the attachment 14 is designed to be in the state shown in FIG. 4A when the main shaft 10 is rotating in one direction at low speed, and in the state shown in FIG. 4B when the main shaft 10 is rotating at high speed in reverse rotation. It is designed to be.

Of course, the attachment 12 maintains the relationship between the engaging member 17 and the protrusion 16 so that power is transmitted at high speeds.

Therefore, at high speed, as a food processor,
Furthermore, at low speeds, it can be used for bread kneading and whipping.

Furthermore, if attachment 14 is incorrectly equipped at high speed,
The attachment 14 is pushed up, no power is transmitted, and there is no danger.

In this way, the present invention uses unidirectional rotation of the power part for high speed,
Since it rotates in the other direction at a low speed and is equipped with a selection of attachments to suit each type of cooking, it is possible to safely perform many types of cooking with one device, and its practical value is extremely great.
