Abstract

PURPOSE:To improve the cutting/crushing performance and to improve the durability of a cutting edge without changing a cutter by switching the rotational direction in accordance with the kind of food to be worked. CONSTITUTION:Power of a motor 3 which is contained in a main body 1, and whose rotational direction is switched by a forward/backward rotation switching device 2 is transferred to a shaft 7 through a pulley 4, a belt 5 and a pulley 6. The shaft 7 passes through a vessel 8, and is fitted to a freely attachable/ detachable rotating body 9 accompanied with a turn-stopper. Also, on the rotating body 9, a cutter 10 is provided, and on the vessel 8, a cover 11 for covering the upper opening part is provided. Subsequently, in a cutter 21, cutting blades 21a, 21b whose cutting edge angles theta1, theta2 in the forward turn direction and the backward turn direction are different from each other are provided in a rotating body 22, and the cutting edge angles theta1, theta2 of the cutting blade 21a, 21b are set as theta1<theta2. In such a way, at the time of cutting soft food, the cutting blade 21a is used by operating in the forward turn direction, and at the time of crushing hard food, the cutting blade 21b is used by operating in the backward turn direction.

、全ての食品を同一の刃物で加工するものであった。BACKGROUND OF THE INVENTION Conventionally, in this type of cooking device, a cutter 31 is generally provided on a rotating body 32 that rotates in one direction, as shown in FIG. 5, and all foods are processed with the same cutter. there were.

発明が解決しようとする課題 しかし、このような従来の調理器では、果物や野菜など
の柔らかい食品の切削も、乾燥した豆などの堅い食品の
粉砕も同じ刃物で行なうため、切削や粉砕に最適な刃物
、つまり刃先角度がより鋭利な刃物にすると、堅い食品
の粉砕時の刃先の耐久性が低下し、逆に刃先の耐久性を
向上するために刃先角度を大きくしすぎると、柔らかい
食品の切削時に、切削抵抗が大きくなり切削性能が低下
するという相反する問題があり、この二つの問題を同時
に解決することは困難であった。Problems that the invention aims to solve However, with these conventional cookers, the same blade is used to cut soft foods such as fruits and vegetables and crush hard foods such as dried beans, making them ideal for cutting and crushing. If you use a sharper knife, that is, a knife with a sharper edge angle, the durability of the edge will decrease when grinding hard foods, and conversely, if you increase the edge angle too much to improve the durability of the edge, it will reduce the durability of the edge when grinding hard foods. During cutting, there are contradictory problems in that cutting resistance increases and cutting performance deteriorates, and it has been difficult to solve these two problems at the same time.

本発明はこのような課題を解決するため、加工する食品
の種類に応じて最適条件で加工することができる電動調
理器を提供するこきを目的とする。In order to solve these problems, the present invention aims to provide an electric cooker that can process foods under optimal conditions depending on the type of food to be processed.

課題を解決するための手段 本発明は上記目的を達成するために、モータにより容器

物を設けたものである。Means for Solving the Problems In order to achieve the above object, the present invention includes a rotating body driven in a container by a motor, and a forward/reverse rotation switching device for this rotating body. On the other hand, a blade with a different cutting edge angle or an angle between the cutting edge line on the same radius and the radial direction of the rotating body, or a combination thereof is provided.

作用 本発明は、上記した構成により、加工する食品の種類に
応じて、正逆回転方向を切り換えることにより最適な刃
物で食品を加工するものである。Function: According to the present invention, with the above-described configuration, food is processed with an optimal cutter by switching between forward and reverse rotation directions depending on the type of food to be processed.

つまり、柔らかな食品の切削時は刃先角度小の刃物で食
品を加工し、堅い食品の粉砕時は刃先角度大の刃物で食
品を加工することとなる。In other words, when cutting soft foods, the food is processed with a knife with a small edge angle, and when grinding hard foods, the food is processed with a knife with a large edge angle.

実施例 以下本発明の電動調理器の実施例について第１図〜第４

However, when looking at the cutting edge angle along the food processing direction, the angle of the cutting edge is θ5 and θ6, and there is no struggle between θ3 and θ4, and the cutting edge 31a in the forward direction is better at cutting in the reverse direction. Blade 3
It is sharper than 1b. Therefore, when cutting soft foods, the cutting blade 31a is operated in the forward direction, and when grinding hard foods, the cutting blade 31b is operated in the reverse direction.
