Description

HEATING DAY DEVICE

The utility model relates to the field of electrothermia and can be used in heating devices made using flat electric heaters.

A device for heating, containing a flat electric heater with a non-metallic resistive element, electrodes and protective insulating layers (see author's certificate No. 542361, N 05 B 3/34, 1977, USSR). The disadvantages of the known device for heating include the presence of sharp edges on the insulating field, damage to which upon involuntary impacts by an edge leads to delamination of the insulation, which violates the continuity of the electric heater and can lead to damage to the resistive element, loss of presentation and failure.

These disadvantages are overcome in an improved heating device comprising a flat electric heating panel with a fringe supporting a support (Patent No. 1777659, Н 05 В 3 / 36.1992, USSR). However, this device also has disadvantages. Minimizing the thickness and cross-section of the edging to acceptable sizes, which provide reliable protection of the sharp edges of the electric heater from chips and delaminations, leads to an increase in the flexibility of a flat electric heater, bending and warping under thermal conditions, and deteriorating consumer properties when used. An increase in the thickness of the insulating layers and the dimensions of the cross-section of the edging frame leads to an increase in the mass of the electric heater and unnecessary material costs associated with its manufacture, which is also disadvantageous.

As a prototype adopted a device for heating according to patent J6 1777659. The main objective of the development is to create a device for heating, based on a new technical solution, the use of which would eliminate the indicated drawbacks, new 5 Н05 В 3/28

Improve reliability and operational efficiency in the field.

The purpose of the utility model is to improve its operational properties.

The task and the specified goal are respectively solved and achieved in a new technical solution by increasing the rigidity of the edging of a flat electric heating panel.

To this end, in a heating device comprising a flat electric heating panel with a fringing bearing a support, the fringing of its flat electric heating panel is made in the form of a pair of parallel-mounted frames fastened together by profiled spacers.

The distinctive features of the device for heating are the following significant features:

- the execution of the edging of a flat electric heating panel in the form of a pair of frames,

- at the same time ustanoadshnmkh among themselves,

- fastened with profiled spacers.

The essence of the utility model is illustrated by drawings. Figure 1 presents a General view of the device for heating in isometry. Figure 2 is a plan view thereof. In FIG. 3 is a side view. In FIG. 4 is a plan view. Figure 5 is a section along aa. Figure 6 is a section along BB. Figure 7 is a section along BB.

The heating device comprises a flat electric heating panel I, a fringing made in the form of paired parallel frames 2 and 3, fastened together by profiled spacers 4, one of the frames 2 or 3 covering the edge of the flat electric heating panel I along its entire contour, and the other is at a distance from it, equal to the size of the gap 5 between them, determined by the length of the spacers 4, fastened to the frames 2 and 3 by means of screws 6 and glue. Support frame 7 is fixed on the frame 2, designed to support the heating device in a horizontal operating position. Profiled spacers 4 may have a circular cylindrical; spherical or zigzag shape and to be made in the form of knitting needles, plates, mesh, mesh structure of the willows of the material, similarly as frames 2 and 3,

for example, wood, polyurethane, rubber or fiberglass. Frames 2 and 3 and profiled put 4 on surfaces 8, 9 and 10 can be made smoothly glossy or decorative. The current leads II and 12 of the flat electric heating panel I are equipped with an electrical connector 13 and a plug 14. The flat electric heating panel I is a layered structure made of non-metallic materials containing a resistive element 15 with electrodes 16 and 17, protected by a coating layer 18 and 19. For ease of assembly and reliability of fastening, the edging frame 2 has grooves 20 for placement and fastening by the edges of the plane Coy electric heating panel I.

Using the device for heating is as follows. When you turn on the plug 14 in the power supply, heat from the resistive element 15 is transferred through the layers of the coating 18 to the box 21, for example, for heating dishes.

Tests of a sample of a heating device made using a new technical solution showed positive results and the feasibility of its industrial production.
