RU178872U1 - SLIDING KNIFE KNIFE FOR KNIFE - Google Patents

Abstract

A nozzle for a power electric drive, mainly a food processor for cutting food products into cubes, the body of which consists of a top cover with a vertical inlet channel, a round-shaped working chamber, a knife-divider assembly located inside the working chamber directly under the cover, a fixed lattice-knife assembly is claimed located under the node of the knife-divider, the output channel of the finished product. The main difference from the known solutions is that the lock of the knife-divider assembly to the top cover is in the form of a movable element with an oval hole of variable width. For fixing, the node of the knife-divider contains a shaft with a groove.

Description

The inventive utility model relates to household kitchen appliances, in particular to nozzles for a power electric drive - for example, for a food processor, mainly for cutting products.

The level of technology.

Currently, there are several varieties of nozzles, similar to the claimed.

For example, W02010012727A1 and DE202012103248U1 disclose the design of a locking device that secures the cover on the body. The main feature is to transmit the force in the axial direction from the rotating unit with the knife to the body in order to reduce the deflection of the rotating unit of the knife and the corresponding increase in the gap between the fixed knives and the movable one. W02010012727A1 discloses a cover fixing device on a housing with a force receiving force element in the form of a locking ring.

A family of devices is known in which the lid is fixed to the housing using snap locks. For example, patent RU 2490118.

Most devices with bayonet-mounted housing and cover, such as Kenwood MGX400

(https://www.manualslib.com/manual/1095385/Kenwood-Mgx400.html#manual - description), and with latches made with a round or close to round shape lid.

However, the listed and many other documents are devoted to a greater degree to the organization of the operation of knives and to protect them from breakage and abnormal operating modes.

All existing technical solutions for nozzles for the harvester have a significant drawback, namely the difficulty of fixing the nodes of the movable and fixed knives.

One of the main factors affecting the simplicity and / or reliability of the assembly is the junction of the nodes of the movable and fixed knives.

In known, including the above-mentioned technical solutions, the connection is performed by fixing on the peripheral part of the nodes, or fixing a previously assembled package of cutting nodes on the peripheral part of one of them, for example, by common latches or bayonet connection. Example, Kenwood MGX400

(https: // www. manual slib.com / manual / 1095365 / Kenwood-Mgx400.html # manual - description).

The disadvantage of fixing latches is the complexity of the design, the presence of additional parts of complex shape, complicating the washing with water at the end of the working cycle.

The Kenwood MGX400 is selected as a prototype.

The technical result achieved by the claimed utility model is to increase the security of the structure from clogging by product particles (noise immunity of the structure), improve the orientation of the mating elements during assembly, increase the speed of assembly, reduce the number of technological operations during assembly.

DESCRIPTION OF THE GRAPHIC MATERIAL FIG. 1. shown device is a prototype

In FIG. 2 shows the composition of parts and components of the device

In FIG. 3 shows a cross section of the device, as well as a side view and top view.

In FIG. 4 shows a lock structure for fixing a movable knife assembly.

The claimed technical result is achieved due to the implementation of the fixing device connecting the nodes of the movable and fixed knives quick disconnect - in the form of a movable latch, actuated without the use of additional tools and having two extreme positions - fixed and unlocked.

DETAILED DESCRIPTION

The claimed technical result is also achieved due to the implementation of the locking device 9, connecting the nodes of the movable 4a and fixed 4b knives quick disconnect - in the form of a movable latch 9, actuated without the use of additional tools and having two extreme positions - fixed (Fig. 4a) and unlocked (Fig 4b).

The nozzle of a food processor designed for cutting food products into cubes, the body of which consists of a top cover 2 with a vertical input channel 5 for loading the product and feeding it to the knives, a working chamber located directly under the top cover of the divider 4a, rotating on a horizontal shaft the plane driven through the shaft by means of a power drive, a fixed knife-grill 4b located inside the housing of the working chamber directly under the knife-divider 4a, the output channel of the finished Product 3. The main difference from the known ones is the fastening of the knife-divider 4a in the node of the fixed knife-grill 4b using a movable latch 9, which enters the groove on the outer surface of the shaft for fixing.

The movable lock 9 contains a rounded oblong hole for fixing in the groove on the outer surface of the shaft, having a variable width, a smaller hole size corresponds to the smallest diameter of the specified groove on the shaft, and the larger size exceeds the shaft diameter of the knife-divider assembly.

The movable latch 9 can be held by the holder 10.

The movable latch 9 may include an additional hole for sliding with your finger.

The movable latch 9 has two extreme positions corresponding to the latched and latched positions.

The device operates as follows.

For the nozzle of a food processor designed for cutting food products into cubes, the design of a locking device 9 for connecting the node 4a of the movable knife-divider and the node 4b of the fixed knife is claimed using the movable lock 9 included in the groove on the outer surface of the shaft of the node of the knife-divider 4a. The movable latch 9 may include a rounded elongated hole having a variable width for fixing in the groove axis of the node of the knife-divider. The greatest width of the specified elongated hole must exceed the diameter of the shaft of the knife-divider, the smallest width of the hole must correspond to the diameter of the groove on the shaft of the node 4a of the knife-divider. The movable latch 9 can be held by the holder 10.

The movable latch 9 may include an additional hole for sliding with your finger.

The movable latch 9 can have two extreme positions - fixed and unlocked.

A movable latch 9, mounted on the node 46 of the fixed knife, is transferred to the unlocked position (figb). The fixed knife assembly 4b is connected to the splitter knife assembly 4a. The movable latch 9 is moved to the locked position (Fig. 4a).

The device is industrially applicable, since each part can be manufactured on industrial equipment in large-scale and mass production.
