IMPLEMENTATION OF THE USEFUL MODEL

IR electric heater contains a base (2), inside of which there is a flat heater (3) (hereinafter referred to as a heater), and a heating panel (1) installed on the base (2), while the heating panel (1) is made in the form of two sheets of glass ( 8, 9), glued together with an adhesive layer (11) - glass "Triplex", while on the inner surface of the glass sheet (8) a low-emission coating (10) is made, on the surface of which metallized current-carrying buses (6) with electrical leads ( 7) to supply power to the IR heater. On the inner surface of the second glass sheet (9), only a low-emission coating (10) or a low-emission coating (10) can be made, on the surface of which metallized current-carrying buses (6) with electrical leads (7) are applied. As glass with a low-emission coating (10), silicate tempered K-glass is used, and as glass without a low-emission coating (10), silicate tempered glass is used.

The heating panel (1) can contain more than two sheets glued together with an adhesive layer (11), while a low-emission coating (10) is made on the inner surface of one of the glass sheets, on the surface of which metallized current-carrying buses (12) with electrical leads ( 7), and at least on the inner surface of the remaining glasses in the heating panel (1) they are made without a low-emission coating (10), only a low-emission coating (10), or a low-emission coating (10), on the surface of which metallized current-carrying buses are applied (6) with electrical leads (7).

Metallized bus bars (6) are applied by the gas-dynamic method, which is based on the effect of fixing solid particles on a surface moving at supersonic speed. The tire application technology includes heating compressed air, forming a supersonic air flow, feeding a powder material, accelerating it by a supersonic air flow and directing it to the surface of the workpiece. Powders of metals (copper, aluminum, zinc), alloys or their mechanical mixtures with abrasive fractions can be used as powder materials for the formation of current-carrying buses.

As the heater (3), any known flat heaters with metal, ceramic heaters, including infrared heaters, are used, for example, the heater (3) has a structure similar to that of the heating panel (1) described above. The heater (3) is fixed inside the base (2) on its lateral sides parallel to the horizontal plane, or at an angle β up to 90 ⁰ to the horizontal plane. One or more heaters can be fixed in the base (2). When using multiple heaters, they are fixed on one horizontal line and can be tilted at the same or different angles. The inclination of the heater (3) ensures that foreign bodies and particles that have fallen on the heater (3) are rolled off during operation in an environment in which a lot of moisture accumulates on the sole of the shoe. The heater (3) is installed under the grate (4) installed on the upper surface of the base.

On the low-emission coating (10), electrically insulated zones (5) are made in the form of a track through which no electric current passes, therefore, the electrically insulated zones (5) do not heat up. The tracks are made in the form of a strip of 0.5-1 mm of various configurations and can be made in the form of a straight or curved strip, a closed strip that forms various geometric shapes, for example, circles, hexagons, etc. The electrically insulated zones (5) provide a decrease in the released specific power, therefore, makes it possible to obtain an IR heater of a given power during the manufacturing process, which ensures the efficiency of simultaneous heating of all parts of the user's body, i.e. there is no overheating or no heating of the user's body.

The heating panel (1) is installed vertically or at an angle α of no more than 45 ^° (from –45 ^° to +45 ^° ) to the vertical plane. The heating panel is installed through a rectangular hole in the base (2) in the channel located at the bottom of the base (2). Fixation in the channel is carried out by means of damper elements adjacent to the surface of the heating panel and a clamping bar installed between the channel and the damper element. Installation of the heating panel (1) allows the user to lean his back on the heating panel (1) at an angle, ensures the efficiency of simultaneous heating of all parts of the user's body and the minimum time for the transfer of thermal energy from the heating panel (1) to the user's body, because the user's back and back of the legs are at the same time in contact with the heating panel (1). Heating panel (1) a rectangular hole in the base is located at a distance from the edge of the rear surface of the base (2), which allows the formation of a protrusion (12) in the rear of the product after installing the heating panel (1), which ensures the formation of the center of mass line within the dimensions of the base (2), which prevents the IR heater from tipping over, therefore, injury safety when using the IR heater increases and provides the possibility of non-stationary installation (mobility) of the IR heater. For the possibility of rigid installation of the IR heater, the base (2) has three holes in the lower part for fixing it to the floor / ground surface using anchors or a similar fixation method. At an angle α of more than 45 ^°, the stability of the IR heater is disturbed, which can lead to overturning, therefore, the efficiency of simultaneous heating of all parts of the user's body and the minimum time for transferring thermal energy from the heating panel (1) to the user's body are ensured.

The use of a heater (3) and a heating panel (1) for heating ensures the efficiency of simultaneous heating of all parts of the user's body.

On the rear side of the IR heater, on the base (2) in the area of the heating panel (1), there is a casing on which the controls for the intensity of the product heating can be located. Under the casing, there is a sealed switching unit, where the contacts for connecting the heater are concentrated with the possibility of connecting it to a fixed network, or connecting a power cord with grounding for using the heater near a power outlet.

The base of the IR heater is equipped with control and monitoring elements for the heating temperature of the heater (3) and the heating panel (1). By using temperature controllers with temperature sensors, it is possible to reduce the energy consumption of the product and be able to regulate the maximum heating temperature for comfortable use of the heater.

Preferably, the glass used to make the heating panel is made by grinding or polishing the perimeter.

To give an aesthetic look, on the front panel of the heater along the perimeter of one or more glasses, a pattern can be applied by silk-screen printing or by another method.

The safety of the heater is due to the use of glued glass, which means that when the triplex is destroyed, its fragments will not get rid of the adhesive composition and cannot harm health. In addition, when the heated glass is destroyed, electric current ceases to flow through it, which also reduces the risk of electric shock due to the violation of the integrity of the heating panel.

The heater has a metal base (2), it is a metal platform with a channel-shaped reinforcement, it is imperative to connect the ground to the base (2), which also reduces the risk of injury due to electric current.

When tempered glass is used for the manufacture of the heater (3) and the heating panel (1), high mechanical strength of the indicated elements of the IR heater is ensured due to the presence of residual surface stresses in the thickness of the glasses used.

As an adhesive layer (11) when gluing glass sheets (8, 9) in a triplex, various types of adhesive are used, for example, a cured adhesive layer of a solution of a high molecular weight polyester oligomer in methyl methacrylate in the form of a photocurable composition, or a polyvinyl butyral film, or ethyl vinyl acetate film.

The claimed electric infrared heater is designed to heat the human body in adverse environmental conditions, namely, in conditions of low ambient temperature and a long stay in such conditions. In addition, the heater has reliable safe elements in its composition, namely:

the heating element is made of tempered glass glued together, of which at least one has a low-emission conductive coating, which is a source of thermal energy when an electric current passes through it. This coating is directed towards the inside of the formed triplex to ensure electrical safety. When the triplex is destroyed, there are no large fragments with sharp edges, and if the heated glass is destroyed, electric current ceases to flow through it;

the heater is grounded to a metal base, which is also one of the ways to increase the safety of the product;

the product is designed in such a way that during its operation it does not have a tendency to tip over;

the product consists of materials with high mechanical strength, which affects the durability of its service and the possibility of using it in public places.

The declared IR electric heater allows you to form a modular structure consisting of several IR heaters connected by bolting their base bodies (2) together, which allows you to organize modules for heating several users.

The declared IR electric heater can be used:

during public events in the open air to warm up personnel who are outside for a long time at negative temperatures;

at police posts;

at the posts of workers of transport services (for heating personnel who are for a long time at low ambient temperatures);

in recreation areas of winter sports centers (ski resorts, etc.);

in other places where it may be required.

The device operates in the following way (for example, a flat heater with a design similar to that of a heating panel). The user stands on the grate (4) of the base, if necessary, leans back against the heating panel (1). The heating of the human body from the heating panel (1) is carried out by IR radiation, and heating of the human feet is carried out by IR radiation and convection. AC or DC voltage is supplied to the low-emission (conductive) coating (10) of the heating panel (1) of the IR electric heater through electrical leads (7) and metallized metallized current-carrying buses (6). When electric current passes through the low-emission coating (10) of the K-glass sheet (8) of the heating panel (1), heat energy is released on the coating (10), which heats the K-glass sheet (8) over its entire surface to a temperature of no more than 60 ° C, while the glass sheet (8) of the heating panel (1), as a material with a high emissivity value, effectively emits infrared radiation through the surface of the glass sheet (8) of the heating panel (1) of the IR electric heater, as a result of which the entire body of the user is heated. ... When an electric current passes through the low-emission coating (10) of the K-glass sheet (8) of the heater (3), thermal energy is released on it, heating the K-glass sheet (8) over its entire surface to a temperature of no more than 60 ° C, while the glass sheet (8) of the heater (3), as a material with a high emissivity value, effectively emits infrared radiation through the surface of the glass sheet (8) of the heater (3) of the IR electric heater, while the heater (3) is located below the upper surface of the base ( 2), the user's feet are heated due to IR radiation and the transfer of heat generated in the inner space of the base (2) from IR radiation by convection flows, which are caused by the heating of the heater (3), the passage of air flows from under the bottom of the base and the exit of convective flows through the lattice (4).
