Description

Application area

The utility model relates to multifunctional electromechanical household appliances, in particular to combines and / or blenders intended for grinding various products, such as cheese, vegetables, fruits, eggs, etc.

The level of technology.

Two blenders with a nozzle for cutting food products into cubes are known from the prior art (patents RU 138969 dated 03.12.2013 and RU 142656 dated 01.04.2014). The nozzle in both patents is made in the form of a cutting tool rotating around an axis of rotation above the cutting grate and resting on its supporting device with its radial peripheral and sections. The cutting tool is a monolithic part containing two knives with cutting edges, on the radial-peripheral section of each of which an arcuate element is made to fit the support device, and a hub with a shaped hole for the possibility of mounting the cutting tool on the rotation shaft.

Another blender with a nozzle for cutting food products into cubes is also known (patent RU 144806 from 05.21.2014). The nozzle is made in the form of a cutting tool with a cutting grill and is a monolithic part with cutting edges on opposite sides, with arcuate elements on the end parts and with a shaped hole in the center for mounting the cutting tool on the shaft of rotation. The cutting tool on both sides of the shaped hole has an arcuate profile, the cutting edge is formed by horizontal sharpening of the upper part of the cutting tool.

The disadvantage of the above nozzles for cutting food products into cubes, which are part of the blenders, is the connection of the cutting tool and the supporting device, which is carried out only with the help of a hub with a shaped hole on the rotation shaft. That is, when the cutting tool is connected to the support device at the slightest bias, either end or radial runout can occur. Moreover, if the products placed in the blender for grinding are large enough and have an uneven density, then the probability of the aforementioned failure increases. This can lead to earlier deterioration of the blender and a significant reduction in its service life. The problem of reducing wear and increasing the service life can be solved due to a more reliable form of attachment between the supporting device and the cutting tool.

The closest in technical essence is a device for cutting products (RU 2490118 from 07.28.2009), where the nozzle is made in the form of a cutting tool with cutting knives rotating above a flat surface with a cutting grill, and a support device. The cutting knives are made compound, with a shaped hole in the center for mounting the cutting tool on the shaft of rotation, while the end ends of the knives are soldered into a thickening located on the ring-shaped element designed to snap the locking element. The element is a device made in the form of the letter "G", where the upper shelf is horizontal and made curved to find it on the thickening of the annular element a of the cutting tool.

The disadvantage of this device is the connection of the fixing devices with a thickening on the annular element of the cutting tool, which can lead to earlier wear of the device due to:

- the possibility of wear of the thickening made of plastic by casting;

- a straight vertical shelf of the fixing element, which does not fix the support device, due to which the latter can "walk", that is, not be in a rigidly fixed state.

In addition, there remains the possibility of nonspecial damage to the thickening (cut, incision, etc.) both during operation of the device and during cleaning, which will make it impossible to connect the support device and the cutting tool with the help of fixing elements, which will automatically remove the device from system (operation). To solve the problem of increasing the service life: it is possible due to a more reliable form of fastening between the supporting device and the cutting tool.

The objective of the claimed utility model is to create a device for cutting into cubes with a nozzle, allowing a longer operation of the product.

The technical result is achieved by creating a device with a nozzle for cutting into cubes, including a support device, a cutting tool with knives made integral and connected by a hub with a shaped hole in the middle, locking elements and characterized in that the latter are made in such a way that the curved vertical part abuts against the supporting device for rigid holding it, and the horizontal part with a bent end for taking by hands is on the surface of the ring-shaped element, made flat and inside which the ends of the knives are soldered.

A possible development option of the main technical solution is that the locking elements in an amount of at least two pieces are located evenly on the side surface of the supporting device.

A possible development of the main technical solution is that the locking elements can be made of spring steel.

A possible development option for the main technical solution is that the fixing elements can be made of plastic by injection molding.

A development option for the main technical solution is possible, which consists in the fact that the bent end for taking the horizontal part of the fixing element by hands can be located in acute fragility with respect to the horizontal part of the fixing element.

A development option for the main technical solution is possible, which consists in the fact that the bent end for taking the horizontal part of the fixing element by hands can be at right angles to the horizontal part of the fixing element.

To disclose the claimed technical solution of the device with a nozzle for cutting into cubes in FIG. 1-2 is a graphical description, where:

in FIG. 1 shows a device with a nozzle for dicing, in which:

pos. 1 - supporting device; pos. 2 - a cutting tool, which includes knives (item 3), made compound, with a hub with a shaped hole (item 4) in the center for mounting the cutting tool on the shaft of rotation; fixing elements (pos. 5) in the amount of at least two pieces, located evenly on the side surface of the supporting device and holding the cutting tool (pos. 2); pos. 6 - a flat surface of the annular element of the cutting tool, at the end of which, in contrast to the closest analogue, there is no thickening.

At the same time, the locking elements (pos. 5) can be made both from a steel spring and by injection molding.

In FIG. 2 depicts a locking element (item 5), where:

the upper horizontal shelf (pos. 7) is made straight for maximum contact with the flat surface of the ring-shaped element (pos. 6) of the cutting tool (pos. 2) with a bent end for taking it by hand (pos. 8). The vertical shelf (pos. 9) is a curved element, where at point A there is maximum contact with the supporting device (pos. 1).

At the beginning of operation of the device with the nozzle for cutting into cubes, the cutting tool (pos. 2) is installed in the supporting device (pos. 1) and connected to the hub with a shaped hole (pos. 4) in the center on the rotation shaft. After that, the open locking elements (pos. 5) are turned towards the center of the device (shaped hole) and are pushed by their upper horizontal shelves (pos. 7) onto the flat surface (pos. 6) of the ring-shaped element of the cutting tool (pos. 2) until full fit to each other. The locking elements in an amount of at least two pieces are evenly distributed on the side surface of the supporting device.

At the same time: due to the larger plane of contact of the flat surface of the annular element and the upper horizontal shelves (pos. 7) of the fixing elements (pos. 5), a greater degree of pressing of the shelves with respect to the cutting tool arises, which allows it to stabilize when the cutting tool is installed (pos. 2) with a slight bias, which leads to a longer operation of the device. In this case, the contact of the fixing elements (pos. 5) with the supporting device (pos. 1) at point A keeps the latter from “walking”, that is, the supporting device is in a rigidly fixed state. Thus, the above actions together solve the task.

At the same time, for convenience, there is a bent end on the upper shelf of the fixing element, designed for picking up the element (pos. 5) (pos. 5), which allows you to disassemble and assemble the nozzle for dicing. This end can be made at an acute angle or perpendicular to the upper flange of the locking element.

Next, a device with a nozzle for dicing is installed for further operation in a kitchen appliance, in particular a blender, chopper or food processor.
