Description

The utility model relates to household appliances and can be used for whipping, mixing, grinding, etc. food products.

The well-known electric mixer MVR-203 EM / 0, currently manufactured by the Energy Concern in Voronezh, contains an electric drive, including an electric motor, gearbox and other devices for transmitting movement to working bodies, a housing with sockets on the ends and side walls to accommodate the drive units, a set of nozzles.

The disadvantages of this electromixer are:

-higher complexity, increased weight due to the presence of a large number of auxiliary connecting parts (shield, frame, flange, cover, etc.) and fasteners;

-the lack of a single basis for the placement of the main components of the electric drive (electric motor, gearbox) leads to low quality and accuracy of assembly;

-limited functionality, i.e. due to insufficient electric motor power, nozzles such as a meat grinder, vegetable cutter, etc. cannot be used, and an increase in electric motor power is limited by the overall dimensions of the case,

The purpose of the proposed utility model is to reduce the complexity and weight, improve the quality of the assembly, expand the functionality.

This goal is achieved by the fact that in an electric mixer containing an electric motor, including a motor, fan, speed switch, a worm gear with two worm wheels and two hubs for installing nozzles, an ejector, a flange for attaching high-speed nozzles and a housing consisting of two parts, a cast base with a flange for attaching high-speed nozzles, with niches and holes for installing and securing an electric motor, fan, worm gear, worm wheel and hub otorrhea are integrally formed, and the speed selector and stripper are combined in one assembly mounted on the housing, the bottom of which there tsrisposobleniv organized for laying the cord.

Figure 1 shows the design of the electronic mixer, General view; on d.2 view rim fsh1; on fig.Zonation about ravorazvavnyh aries nodes electric drive; figure 4 body; figure 5 switch operating modes; Fig.6 ejector.

The electric mixer consists of an electric drive, which includes an electric motor I, on a shaft 2 of which a coupling 3 is mounted on one side, which serves to connect the working bodies of high-speed nozzles, and on the other hand, a fan 4 and a worm 5 are made integral with the shaft 2. Worm 5 is paired with worm wheels 6, 7 made at the same time with hubs 8, 9. Hubs 8,9 serve for connecting working bodies of low-speed nozzles and at the same time, the outer surface ıx is a sliding bearing. Worm 5 with worm wheels 6.7 form a worm gear with a gear ratio of I 30. The electric drive also includes a speed switch 10, and an ejector P. Speed switch 10 has four half-positions corresponding to zero, low, medium and high frequency of rotation of the electric motor I. For convenience in operation, the ejector II and the speed switch 10 are combined into one node mounted on the housing. The case consists of two parts 12, 13 made of plastic AN) -202 @ -31 TU6-05-1587-84. The connection of the housing parts 12.13 is carried out by screws and latches.

The housing has holes for installing nozzles. In the back of the case, high-speed nozzles are connected (turbo-esser, mixer cup and coffee grinder). To protect against contact with the shaft 2, when the motor I is operating, there is a shutter 14.

In the lower part of the casing there is a latch button 15, which serves to hold high-speed nozzles, as well as two holes for connecting low-speed nozzles (spiral, frame, corolla beater), which are rotated through a worm gear, and a device 16 for organized laying of the cord 17 for connecting the electromixer to network 220 V.ch

To install the main parts of the electric drive there is a base 18 made by injection molding. Along with the base 18, a flange 19 is made, for connecting high-speed nozzles, as well as niches and holes, for installing and fixing the electric motor I, fan 4, gearbox. At the base 17 there are two openings through which Щ) the hubs of 8.9 worm wheels 6.7 go around. Metal bushings are inserted into these holes, which serve as cages of sliding bearings (hubs).

Elvctra preparation (jixgra to work

Set the speed selector II to position O corresponding to zero speed. In this position, motor I is disconnected from the power supply.

Whipping mode

For the preparation of light, liquid mixtures, such as: cream, batter, egg whites, sauces, etc. one or two frame nimbuses are inserted into the holes of the hubs with a light pressure. The power cord 17 is connected to AC power. Set the speed selector 10 to one of three combinations. Position I corresponds to the minimum frequency of rotation of the electric motor I. In this position, part of the stator winding of the electric motor is energized by the alternating current network. In position 2, a single-period voltage supplied from the network through a rectifier diode (not shown) is supplied to the stator winding of the electric motor and the speed of the electric motor I increases. In position 3, the entire stator winding is connected to AC power. In this position, the maximum speed is 16000-18000 s. When the speed switch 10 is set to one of three positions, the shaft 2 starts to rotate. The rotation from the shaft 2 and the worm 5 is transmitted to the worm wheels 6.7, and, accordingly, to the hubs 8.9. Together with the hubs 8.9, the nozzles rotate. After preparing the mixture, the speed switch 10 is set to position O, and the nozzles are removed by pressing the ejector button II. The pusher rods II press on the nozzle rods, which come out of sticking with the hubs 8.9. After disconnecting the nozzles, the ejector II rotates to its original position using a spring located in the ejector.

Mixer mode

For chopping vegetables and fruits, making cocktails, grinding coffee, a connecting hole is used located at the rear of the case. To do this, it is necessary to move the curtain 14, insert the counterpart of the coupling 3 located, for example, on the shaft of the coffee grinder. In the connection flange 19 of the internal TB I will answer Еу / i / acTb,

position / sleep the coffee grinder case, I | ga9 at w / 5 with the latch of the latch button 15. Set the speed switch 10 to position O, connect the power cord 17 to the power source. Speed switch 10 put in one of three positions. To electric motor I

voltage is supplied from the power source. Shaft 2 begins to rotate, Rotating shaft 2 hvr§z clutch 3 is transmitted to the working bodies (knives) of high-speed nozzles.

After grinding the coffee, set the speed switch 10 to position O, press the latch button and remove the coffee grinder.

To reduce the collector pulsations arising during the operation of the electric motor I, the radio interference filter is included in the electric drive (not shown in Fig.).

Thus, using the unified LIT09 base in the proposed electric mixer on which there is a flange for connecting high-speed nozzles, niches and holes for installing and securing an electric motor, fan, worm gear, in which the worm wheels and hubs are made at the same time, this reduces the complexity by eliminating additional installation - connecting and fastening parts, reduce weight, improve the quality and accuracy of assembly, put a more powerful electric motor and thereby expand the functionality The new features of the electromixer due to the compact placement of the main volumetric units of the electric drive (electric motor, fan, worm gear).

For convenience in work, the speed switch and the ejector are combined into one node.

Currently 25 pieces are manufactured and tested. electric mixers made in accordance with the proposed application for a utility model. Tests confirmed the reliable operation of the proposed electric mixer.
