Description

This utility model relates to the technique of drying food products and can find application in electrical devices for drying fruits, berries and vegetables, mainly in domestic conditions.

A device is known for drying berries, vegetables and fruits, comprising a cylindrical body vertically mounted on legs with a bottom, an electric heater and an axial fan located inside the cylindrical body above the bottom and electrically connected to a control unit mounted on the body, while the bottom surface swept by the fan blades is made perforated, and trays for placement of products to be dried, an electric heater is placed above the fan relative to the bottom of the case, the fan motor and electric the heater is rigidly fixed to the crosspiece, attached to the body, the food trays are made in the form of coarse sieves mounted on top of each other over the electric heater, a temperature regulator is installed inside the body volume, electrically connected to the control unit, and the fan blades are placed in a cylindrical ring rigidly attached to the bottom of the body (patent RU 104021 U1, filing date 10/27/2010, published 05/10/2011).

A well-known household electric dryer containing a base with holes, an engine, an impeller located in the discharge chamber, heating elements, belt-mounted pallets and a top cover with an outlet channel, characterized in that there is an annular gap between the outer and inner walls of each pallet, the cross-sectional area of the discharge chamber decreases from the center to the periphery, and the outlet of the discharge chamber communicates with an annular gap (patent RU 149711 U1, filing date 03/14/2014, published 01/20/2015).

For example, electric household dryers for fruits and vegetables SUPRA DFS-311 and Polaris PFD 0605D are also known, which include a housing with an electronic control element installed in it with the possibility of setting the drying time and temperature, as well as a heating element and a fan with a vertical nozzle, This is equipped with a drying unit in the form of belt-mounted removable trays and lids (https://www.supra.ru/catalog/sushilki_dlya_fruktov_i_ovoshchey_arkhiv/sushilka_dlya_ovoshchey_i_fruktov_supra_dfs_311/ and https://www-polar i-fruktov / polaris-pfd-0605d /? sphrase_id = 662923).

A common disadvantage of known electric household dryers is the low reliability associated with the possibility of accidental contact with foreign objects (products for drying) on the fan blades, and, as a result, the safety element burns out, the device fails and the device needs to be repaired.

As the closest technical solution, an electric household dryer for vegetables and fruits Ezidri Ultra FD1000 was selected, which contains a housing (base) with a mechanical control element installed with the possibility of setting the drying time and temperature, as well as a heating element, a fan with a vertical nozzle, a drying unit is installed on the body in the form of removable pallets lying on top of each other and a lid with an opening. The pallets are made in the form of sieves and have openings in the central part, each sieve being equipped with two rims of different diameters arranged coaxially (http://www.hvdraflow.co.nz/Ezidri.aspx).

The disadvantage of the closest analogue, as well as well-known household electric dryers, is the low reliability.

A technical problem, the solution of which is provided by the claimed utility model, is the creation of a new design of a household electric dryer, which prevents foreign objects from getting on the impeller blades and breaking the electric dryer.

The technical result obtained by using the inventive utility model is to increase the reliability of the device.

The technical result is achieved by the fact that the household electric dryer contains a base closed with openings and made with holes, in which an engine and a control unit are located under the first cover and impellers and heating elements located above the engine, while sieves are located on the base under the second cover with an aperture having openings in the central part, each sieve is provided with two rims located coaxially, according to a utility model, the electric dryer is provided with a screen laid on the first cover under the holes of the sieves and made with the possibility of passing air.

The present utility model is illustrated by drawings (Fig. 1-2), an example of a household electric dryer on which, however, is not the only possible, but clearly demonstrate the possibility of achieving the claimed technical result. Moreover, the above examples of the claimed utility model do not limit the possibilities of its implementation, not beyond the scope of the utility model, and are not exhaustive.

In FIG. 1 shows a frontal section of the inventive electric dryer, FIG. 2 is an image of leader B.

With reference to FIG. 1-2 are indicated:

1 - the base of the electric dryer;

2 - legs of the electric dryer;

3 - the first cover of the base of the electric dryer;

4 - electric motor;

5 - heating element;

6 - control unit;

7 - safety element;

8 - impeller;

9 - sieves;

10 - the second cover of the electric dryer;

11 - holes of the base 1;

12 - hole cover 10;

13 - holes sieve 9;

14 - the central channel of the electric dryer;

15 - holes cover 3 for air;

16 - sieve 9;

17 sieve 9;

18 - peripheral through channel of the sieves 9;

19 - screen;

20 - holes for air inlet in the sieve 9;

21 - holes for the exit of air from the sieve 9.

According to a utility model, a household electric dryer contains a base 1, which can be performed on legs 2 (Fig. 1). Legs 2 can be equipped with sound absorbing dampers (not shown). In the upper part of the base 1 of the electric dryer, a first cover 3 is installed, which covers the base 1. At the base 1 is an electric motor 4. A heating element 5 and a safety element 7 are attached to the cover 3 of the base 1. A control unit 6 is mounted in the base 1, which can located, for example, in the lateral part of the base 1. At the base 1, an impeller 8 is placed above the engine 4, which serves to pump heated air into the drying zone. For air intake from the atmosphere into the electric dryer, holes 11 are provided, which are located in the base 1 (Fig. 1).

On the base 1 on top of each other, forming tiers, sieves 9 are installed, which are covered from above with a second lid 10 (Fig. 1). To exit the air from the dryer, a hole 12 is provided in the cover 10 of the electric dryer. Each sieve 9 has a hole 13 in the central part, which, when the sieves are installed in tiers, forms a central channel 14 (Fig. 1, 2). For air circulation in the cover 3 of the base 1, holes 15 are made, which can be located under the central channel 14 (Fig. 1, 2).

On the peripheral side of the sieve 9 are equipped with rims 16 and 17 located coaxially one after another with decreasing diameter from the first rim 16 to the second rim 17 (Fig. 1). An annular gap, which is formed between the rims 16 and 17 of the sieves 9, with a tiered arrangement of the latter, forms a peripheral through channel 18 (Fig. 2). The electric dryer is equipped with a screen 19 located on the first cover 3 under the openings 13 of the sieves 9 and made with the possibility of passing air, for example in the form of a grid (Fig. 1, 2). At the inlet of each sieve 9 there is an opening 20 for air inlet, and at the outlet of the sieve 9 there is an opening for air to enter the central channel 14.

The inventive utility model works as follows.

The required number of sieves 9 is installed on the base 1. Through the holes 11 of the base 1, the air enters the dryer and is heated by the heating element 5. Using the impeller 8, air is pumped into the drying zone through the peripheral channel 18. Then, the heated air stream enters through each channel 18 into the sieve 9 through the hole 20, where the products are dried, then the air stream leaves the sieves 9 through the hole 21 in the Central channel 14 and then enters the hole 12 of the cover 10 of the electric dryer and is discharged into the atmosphere. In order to protect the dryer from breakage, a screen 19 is installed on the cover 3, which prevents foreign objects, for example, drying products, from entering through the holes 15 of the cover 3 on the impeller 8 or the engine.
