The technical FIELD TO WHICH the INVENTION RELATES.

The present invention relates to a rotary nozzle, designed to bring the rotation of the drive unit. The nozzle can be used in electric household or kitchen devices kitchen harvesters and the like. The nozzle can be used for grinding, blending, mixing or whipping flowable materials, particularly food products.

BACKGROUND of INVENTION

In the French patent document FR 1397685 disclosed rotary nozzle containing one wire frame extending from the drive shaft of the nozzle. Single wire frame can be divided into three sections or portion along the length of the wire frame, with the first section protrudes outward relative to the drive shaft, the second section includes two spaced to each other at an angle segment and the third section returns the wire frame back to the drive shaft. The second section and the segments are arranged so that during the rotation of the nozzle lower end of the second section behind its upper end. Each angular segment forms a link in a wire frame. The said links are positioned so that they intersect each other, i.e. the wire frame is twisted around its longitudinal axis. According to FR 1397685, so the I form attachments promotes mixing or aeration, achieved through the nozzle.

The problem associated with the known nozzle, is that although is improved mixing, this action of the nozzle is not optimized and may be subject to further refinement.

The OBJECTIVE of the INVENTION

The present invention is directed to improved well-known in the prior art rotary nozzles, in order to optimize the increase in volume when whipping and stirring, adding to the effect of aeration and reduce the time required for material processing.

The INVENTION

The above object is achieved by means of rotary nozzles made with the possibility of bringing into rotation in a given direction of rotation. The nozzle comprises a drive shaft made with the possibility of connection with a driving device, with the drive shaft forms a longitudinal axis around which it rotates the nozzle, and includes a housing nozzle containing at least one wire frame, which is connected to the drive shaft and which extends from the drive shaft in the direction of the longitudinal axis, and after many changes in its direction, is returned to the drive shaft. At least one wire frame contains the first section, containing the first two segment connecting wire is lochnaw frame with the drive shaft, and a second compartment that contains two of the top segment and the bottom two segments. Each upper segment is connected with the corresponding first segment of the first section, along with a corresponding lower segment of the second section. At least one wire frame further comprises a third section containing two third segment, each third segment connected to the third segment and one bottom segment of the second section. Each pair of mutually connected upper and lower segments of the second section form a plane which is essentially parallel to the longitudinal axis or is it at a slight angle, these mutually United upper and lower segments form an angle with respect to each other in said plane, so that the mutually connected upper segments and lower segments have different angular orientation with respect to the longitudinal direction. The upper segments of the second section inclined relative to the longitudinal axis at an angle in the range from 15° to 35°.

The special geometry of the nozzle of the present invention significantly reduces the time of application and significantly increase whipped the volume of the food product compared to other wire framework.

The inventors have found that stirring, or the effect of aeration nasadq the prior art is not optimal, as this effect is achieved only through part of its second section. Therefore, as found by the authors of the invention, the mixing and/or the effect of aeration can be improved provided that no angular velocity, which is the same for any rotating part of the nozzle, and the actual speed of the upper and lower segments of the second section will be essentially constant and maximum essentially over the entire height of the second section. This was achieved through the fact that each pair of mutually connected upper and lower segments of the second section, i.e. each "link" wire frame forms a plane that is essentially parallel to the longitudinal axis. This leads to the fact that each part of such a link will have the same, maximum speed during the rotation of the nozzle. Such improvement of the nozzle is known from the prior art, in which the nozzle to provide maximum speed only on a small portion of the segments of the second section.

It should be understood that in the context of the present invention, the term "small angle" is used to denote the angles between the plane in which are located respective mutually United upper and lower segments and the longitudinal axis that leads to the actual speed of these segments is close or equal to the maximum is the value. Thus, the plane, which has a small angle relative to the longitudinal axis, is within the scope of the invention. In practice, these angles can be in the range from zero to fifteen degrees in either direction, i.e. during the rotation of the first nozzle section describes the circumference of a larger outer diameter than the third section, and Vice versa.

According to a variant implementation, the angle between the upper and lower segments is in the range from 120° to 140°, preferably about 130°. As it turned out, this range of angles provides very good results aeration flowable materials and, therefore, increasing their volume. In particular, this range of angles gives good results, as for whipping and mixing.

According to a variant implementation, the lower end of the respective upper segment lags behind its upper end, and the upper end of the corresponding lower segment lags behind its lower end in the direction of rotation. During the rotation of the nozzle such an arrangement will allow the lower segments to raise food material upward, and the upper segments to bring down food material down. In addition, churning down the upper segments allows to reduce time of processing of food material.

According to a variant implementation, referred to the lower end of the said lower segment is behind the aforementioned upper end of the said upper end of the said upper segment in the direction of rotation angle of delay, these angle delay is preferably in the range from 5° to 30°. Thus, the upper part of the link formed by the interconnected segments of the second section, is always ahead of its bottom, which effectively prevents the displacement of fluid material from the body of the nozzle for rotating the nozzle.

According to a variant implementation, the first segments of the first section inclined at an angle within the range from 0° to 45°, in the direction of the third section and deflected from the plane perpendicular to the longitudinal axis.

According to a variant implementation, the upper segments of the second section inclined relative to the longitudinal axis at an angle, comprising about 25°.

According to a variant implementation, the third segment of the third section is located at an angle to the drive shaft, which is in the range from 0° to 30° and deflected from the plane perpendicular to the longitudinal axis, the said angle is preferably about 10°. The reduction of this angle will allow the nozzle to process more material with each rotation, which allows to reduce the processing time. On the other hand, the increase of this angle improves the control nozzle. The optimum was found angle of about 10°.

According to a variant implementation of the mentioned wire frame has a round cross section. This keygen is provides good workability of the wire frame.

According to a variant implementation, the attachment contains the two above-mentioned wire frame, in order to further improve the performance of the nozzle.

The invention additionally relates to a kitchen appliance, food processor, and similar devices, comprising a housing and a drive unit installed in the above case, with the aforementioned drive device comprises a connecting device for connection with the rotary nozzle in accordance with the invention.

Other rotary nozzles are known, e.g. from GB-977, 761, in which is disclosed a nozzle comprising at least one wiry nozzle element, originating from the drive shaft, then continued in the direction of the drive shaft, and, finally, after two changes of direction, returning back to the drive shaft. The wire element can essentially be divided into three sections. The first section is a straight section extending from the drive shaft. The second section also rectilinear and extends along the drive shaft. The third section is rectilinear and extends from the end of the second section to the drive shaft. During the rotation of the nozzle end of the first section ahead of the end of the third section. The first, second and third sections are initially made by the fold is of metal wire into a flat rectangle. Then two opposite sides, which must form the second section, arches out of the original plane of the rectangle in opposite directions, so that one half of the rectangle is in a plane having a slope relative to the plane of the other half. Due to the bending, the second section have a certain angle with respect to the longitudinal axis of the drive shaft. Due to the inclined second section disclosed in GB-977761 nozzle during operation has a striking influence on the material being processed. At the same time, is relatively mild aeration effect.

Similarly, in patent US-5590962 disclosed nozzle containing a wire element which is serially from the first, second and third sections. Patent US-5590962 is intended to ensure the improvement of the nozzles so as to exclude invalid sprinkling of food material during mixing. During operation the first section, which is the closest section to the drive shaft, behind the third section. The second section is divided into an upper segment and lower segment of approximately equal length. Due to the fact that the upper segment behind the lower segment, when viewed in the direction of rotation of the nozzle, the food material is especially intensively treated lower segments, moves or is braceletsa up. The food material in the lower segments rises upwards and radially outwards. In the upper segments of the food material moves only in the radial outward direction, i.e. horizontally, as these segments are directed slightly radially outward, but essentially parallel to the drive shaft. In the result of rising food material is accelerated horizontally, allowing you to avoid splashing of food material. Besides the fact that the upper segments being parallel to the drive shaft, the patent US-5590962 prescribes the placement of the lower segments at an angle equal to at least 60 degrees or more relative to the drive shaft, for optimum increase the amount of food material.

Additional preferred embodiments of the rotary nozzle in accordance with the invention described in the claims and in the following description with reference to the drawings, in which:

Figure 1 presents a side view of the nozzle according to the present invention;

Figure 2 presents a perspective view of the nozzle shown in figure 1; and

3 shows the bottom view of the nozzle shown in figure 1.

DETAILED DESCRIPTION of EXAMPLES

According to the present invention, figures 1, 2 and 3 shows a rotary beater or whisk 1. The nozzle 1 comprises a drive shaft 2, one is the once which has connecting part 4, adapted for connection with a driving device of kitchen appliance, food processor, or similar devices. The drive shaft 2 forms a longitudinal axis 16 and can be fitted with devices such as nasal clamp for secure attachment of the drive shaft 2 of the said cooking device. Drive unit can be manual or motor-driven. The nozzle 1 can be used with electric kitchen appliances, hand or not. Kitchen appliances can, for example, be equipped with one nozzle or two nozzles, rotating in opposite directions. According to the present invention, the nozzle 1 is rotated in the direction of rotation indicated by the arrow R. the Speed of rotation may be, for example, in the range from 300 to 1200 or 1500 rpm in Other words, according to the present invention, the nozzle 1 is particularly suitable for use with food products.

The free end 12 of the drive shaft 2 opposite to the connecting part 4, provided with a housing 6 of the nozzle. Case 6 nozzle includes one or more wire frames 8 and 10. However, it should be noted that it is also possible to equip the nozzle 1 only one wire frame. The invention will be further described with reference to the rotational nozzle containing two wire frames, but not to limit the flax sense.

Each wire frame 8 and 10 has a height h and a width W. In the illustrated embodiment, the wire frame 8 and 10 are perpendicular to each other, i.e. at an angle of about 90°. This is best seen in figure 3. Therefore, the wire frame 8 and 10 are uniformly distributed along the direction R of rotation.

Wire frame 8 and 10 are made by bending a wire, preferably a metal wire, in the specified form. The free ends of the wire frame 8 and 10 connected to the free end 12 of the drive shaft 2 through the sleeve. However, there are other ways of fastening the wire frame to the drive shaft 2, for example, by welding. Wire frame 8 and 10 intersect with each other at the lower end of the nozzle 1. Wire frame 8 and 10 preferably consists of a wire having a circular cross-section, but not in a restrictive sense. Wire frame 8 and 10 are preferably connected to each other at the intersection of 14, where both wire frames overlap with each other. This increases the mechanical resistance of the nozzle 1.

Figures 1 and 2 detail shows the General form of wire frame 8 and 10. Wire frame 8 and 10 contain the first section I, located in the upper part of the housing 6 of the nozzle, the second section II, located in the Central part of the body 6 of the nozzle, and a third section III, located in the lower part is of orpus 6 nozzles. This is shown in figure 1.

Each first section I contains the first two segment 8A, 8h, 10A, 10h, which in the example of figure 2 are essentially straight and directed essentially radially outward from the drive shaft 2. It is also possible that the first segments 8A, 8h, 10A, 10h, will have a curved shape. It is shown that the first segments 8A, 8h, 10A, 10h have the angle from the Y plane (the plane Y shown only in two dimensions in figure 1, but the plane Y perpendicular to the longitudinal axis 16 of the nozzle 1 according to the third section III of the housing 6 of the nozzle. In a practical embodiment, the angle may be in the range from 0° to 45°, or in the range from 10° to 40°, for example about 30°. However, it is also possible and other values of the angle. The first section I connects the second section II to the drive shaft 2. For practical reasons, the first section is also made of wire, but alternatively may, for example, have the form of a disk. There are also other ways to create the first section within the scope of the invention.

Each second section II single wire frame contains two upper segment 8b, 8g, 10b, 10g and two lower segment 8c, 8f, 10c, 10f. In the figures the upper segments shown pointing downwards. The upper segments 8b, 8g, 10b, 10g are located in a plane having an angle of inclination β relative to the longitudinal axis 16.

In practice Eskom embodiment, the angle β is in the range from 15° to 35°, the optimal value is about 25°. In addition, the lower segments are located in a plane which is inclined to the longitudinal axis 16 at an angle in the range from 15° to 35°, or preferably from 20° to 30°, the optimal value is from about 22° to 25 °.

Two lower segment 8c, 8f, 10c, 10f also on the figures is directed downward and located at an angle γ relative to the respective upper segments with which they are connected. As shown in figure 2 and 3, each wire frame consists of two mutually connected upper and lower segment 8b, 8c; 8g, 8f; 10b, 10c and 10g, 10f, so that each mutually connected pair of upper and lower segments forms a link in the body 6 of the nozzle. As shown in figure 2 and 3, such links or each interconnected upper and lower segment of the second section II of the form corresponding to the plane of XA and Xb, which are essentially parallel to the longitudinal axis 16. In other words, the mentioned plane XA and Xb do not intersect the longitudinal axis 16. As best shown in figure 3, this leads to the fact that the second section II and its segments are located as close as possible to the outer radius or width W of the housing 6 of the nozzle and, thus, rotation of the nozzle 1 they all have one actual speed (not just speed). It should be noted that the plane of XA and Xb may also is be located at small angles relative to the longitudinal axis 16. In fact, it is clear that in the context of the present invention, the term "small angle" is used to denote the angles at which the actual speed of these segments is close or equal to the maximum value. Thus, the plane, which has a small angle relative to the longitudinal axis, is within the scope of the invention. In practice, these angles can be in the range from zero to fifteen degrees in either direction, i.e. during the rotation of the first nozzle section describes the circumference of a larger outer diameter than the third section, and Vice versa.

In the above-mentioned planes XA and Xb corresponding mutually United upper and lower segments form an angle γ with respect to each other, these segments have different angular orientation relative to the longitudinal axis 16. The angle γ is essentially in the middle of the second section II, i.e. between the upper and lower segments having approximately the same length. The angle γ is about 130° (figure 1 and 2). The angle γ is a compromise for whipping and mixing and preferably is in the range from 120° to 140°. Optimal for whipping the angle γ is about 140°, while the optimal mixing angle γ is about 120°.

Every third section contains two third segment 8d, 8e; 10d, 10e extending essentially pleased the material outward relative to the longitudinal direction 16, like the first segment of the first section. The third segment of the third section can be inclined at an angle δ from plane Z to the free end 12 of the drive shaft 2 (the Z plane is shown in figure 1 only in two dimensions, but it is perpendicular to the longitudinal axis 16 of the nozzle 1).

In a practical embodiment, angle δ may be in the range from 0° to 30°, for example about 10°. Decrease the angle δ will allow the nozzle to capture more of the processed material at each rotation, thereby reducing the processing time. On the other hand, increasing the angle δ improves the control nozzle. Optimum recognized as the angle δ of about 10°.

Every third segment 8d, 8e; 10d, 10e connected with other third segment of the same wire frame 8 and 10 so as to close the mentioned wire frame, connecting with each other, both of the second section II of the corresponding wire frame.

Turning to the second section II single wire frames, in particular, to a single link, formed by two mutually connected by upper and lower segments, as can be seen in figure 2, referred to a mutually United upper segments and lower segments have mutually opposite angular orientation with respect to the direction R of rotation, so that the lower end 50 of the respective upper segment 8g behind its upper end 30, and so that the top end 50, converging with the lower end of the upper segment corresponding to the lower segment 8f behind its lower end 40 in the direction R of rotation. In the processed fluid material rises up the lower segment (segments) and break down the top segment (segments).

An additional result is that third segments 8d, 8e; 10d, 10e of the third section behind the first segments 8A, 8h, 10A, 10h first section I on the angle ε in the direction R of rotation. In a practical embodiment, the angle ε may be in the range from 5° to 30°, for example, may be about 15°. Thus, the upper part of the link formed by mutually connected segments in the second section, always ahead of her bottom, which effectively prevents the displacement of fluid material from the body of the nozzle for rotating the nozzle.

Thus, the second section II is located between the first section I and the third section III, so that the maximum diameter of the wire part (width W) is not exceeded, although the ends of the lower and upper segments of the second section are located essentially at the same distance of about 0.5*W, from the longitudinal axis 16.

Proposed by the present invention, the nozzle is an improvement compared to existing rotary nozzles. The advantage of the above described nozzle making is in its geometric form, providing a significant reduction in the time use and a significant increase in the volume of treated material compared to straight wire frames. Proposed by the present invention, the nozzle is cheap and provides an attractive basic functions for hand mixer.

The special geometry of the nozzle of the present invention significantly reduces the time of application and significantly increase whipped the volume of the food material in comparison with the other wire frames. During the rotation of the nozzle, the lower segments of the second sections II raise food ingredients, while the upper segments of the second section II knock food ingredients down. Through this procedure in the ingredients enter the air, and increases the amount compared to other existing wire frames. According to the invention, the nozzle is further enhanced due to the fact that all of these parts of the nozzle, i.e. the upper and lower segments of the second sections, the highest possible speed and mentioned this speed is essentially constant along the entire length of the second section.
