Description

Food Mixer {MIXER FOR FOOD}

The present invention relates to a mixer, and more particularly, to perform various functions such as crushing, cutting, mixing, and chopping various foods such as meat and vegetables in a quick and effective manner, minimizing foods sticking to the surface of the cutter and It is about a food mixer that can reduce the operating time.

Mixer, a kind of food processor, is widely used to finely chop, mix, stir or cut and grind various foods including fruits, vegetables, grains, garlic and peppers. Various types of cutters can be selectively changed and used according to the use.

1 shows an electric mixer disclosed in Korean Utility Model Registration No. 20-0380639 as an example of such a mixer. As shown, a main body 40 having a built-in electric motor and provided with various switches, It is detachably coupled to the upper part, and the center of the bottom surface is engaged with the electric motor shaft to form a rotating shaft which is rotated by receiving the rotational force, and the upper part of the container 10 opened to put food, and the rotating shaft of the container 10 Removably coupled is composed of a cutter 30 for cutting and crushing food according to the rotation of the electric motor and a lid 20 for opening and closing the upper portion of the container (10).

Therefore, when the food is put into the container 10 and the lid 200 is covered, and the electric motor is operated by operating the switch of the main body 40 according to various functions, the cutter 30 engaged with the electric motor shaft rotates in the container 10. The food is cut and crushed.

However, the plate-type general cutter 30 used in such a mixer has a simple shape, and the food is easily attached to the surface due to the nature of being mounted on the bottom surface of the container 10, and the stirring function is extremely poor. The centrifugal force according to the rotation of the cutter 30 is not easily flowed, so only the food in the lower portion of the container 10 is cut and pulverized, and the food in the upper portion cannot be cut and crushed properly.

Not only that, even if the rotating operation is continued, only the food in the lower part is crushed and the cutter 30 remains idle for a predetermined time, and eventually, the food is not cut and crushed evenly and the load of the electric motor is large, causing frequent breakdowns. There is a problem that causes a loss of power.

That is, the food is cut by the contact with the cutter 30 in accordance with the rotation of the electric motor, the food is repeatedly cut in contact with the food repeatedly in accordance with the continuous rotation of the cutter 30, in the process of the food itself Since the sticky ingredients that occur to interfere with the flow of food, the lumps of food that is not finely crushed stagnates on the upper portion of the container 10, thereby preventing smooth grinding.

Accordingly, there have been various proposals for cutters having a technical purpose to improve cutting and grinding ability of food and to reduce operating time.

For example, the grinding cutter disclosed in the Republic of Korea Utility Model No. 20-0415696 has a rotational direction of the cutter at the end of each blade 22 of the rotary knife 20 is formed symmetrically about the axis of rotation, as shown in FIG. The sawtooth 24 is formed in a wavy shape having a predetermined width while forming a plurality of round shapes that are curved at a predetermined curvature in the opposite direction.

However, this is just a tooth 24 is formed on the pair of blades 22, which are simply staggered with each other up and down, and due to the morphological characteristics of the toothed blade 22, such as kimchi or raw sweet potatoes, such as kimchi or raw sweet potatoes, It is suitable for cutting and crushing large foods, but soft foods such as tofu are not easily cut and crushed, and when the cutter is rotated at high speed, the food does not scatter all around in the container and often revolves in a specific position, resulting in perfect Of course, there is a problem in that the grinding is not made, but the electric motor can be operated for a long time.

On the other hand, the grinding blade for the mixer disclosed in Republic of Korea Utility Model No. 20-0424032, the upper blade 20 is formed with an upper blade 21 of the form bent both ends, as shown in Figure 3, and the upper blade It consists of a lower blade 30 installed to intersect with respect to (20), in particular the lower blade 30 is the first blade 32 bent downward and the second blade bent upward from the first blade (32) (33) and the bending blade 34 formed in the one edge part of this 2nd blade 33, and the bending horizontal blade 35 formed in the other edge part.

However, it is bent to extend both ends of the upper blade 20 positioned at the upper side to be inclined at an upward angle, and both ends of the lower blade 30 positioned at the lower side are bent to extend at an angle downwardly, respectively, each of which is extended Since the width of the part is gradually narrowed outwardly, it is merely a morphological feature formed by bending both ends of the upper blade 20 and the lower blade 30 at a monotonous angle so that the time required for cutting and pulverizing food is considerably increased. Long, gaps due to the difference in height between the upper blade 20 and the lower blade 30, the food is not cut and crushed into even particles suitable for the purpose, in particular large or lump-like particles such as garlic, meat or ice Food has the disadvantage of injuring by causing the food to bounce upwards, and when it is operated for a long time, water is produced from the food, and it becomes thin like rice porridge. There is a serious problem of changing into a puzzling state.

In other words, in order to effectively cut and crush food in a bulky or rigid form, food must collide with the cutter, then scatter in all directions, and then collide with the cutter in a continuous manner. Because it is formed in a simple form that is overlooked, the cutting and crushing action does not occur effectively such that food easily adheres to the wall of the container according to the moisture content and viscosity of the food.

Therefore, the present inventor focuses on solving the above-mentioned matters and problems, and performs foods quickly and effectively while uniformly cutting, crushing, mixing, and chopping, minimizing foods sticking to the surface of the cutter, and minimizing the operating time of the blender.
