Description

The utility model relates to personal protective equipment for heating a person at low ambient temperatures without the risk of overcooling the body and can be used in industrial, medical, sports, household, special and military work clothes of operators, personnel who are on scheduled, combat duty, pilots and drivers transport ground, water and air means, so that each of them could timely fulfill the production, planned, operational, tactical or combat mission.

Work in low temperatures, refers to extreme human activities. The problem of maintaining the heat of the human body is very relevant, however, all types of domestic heating protective clothing are morally obsolete. To create a modern heating vest, the peculiarities of the processes of the “man-heating vest-environment” system are taken into account.

Known clothing made in the form of linen containing a heating unit with heating elements connected to a power supply (patent RU No. 2192766, 2002). The clothes are additionally equipped with an electrocardiograph, a control unit. Heating elements are placed on the inside of the right and left halves and back of work clothes. A moisture-absorbing fabric is placed around the perimeter of the heating elements. The heating block contains a set of heating elements designed to be applied to the area of projections of the liver, gall bladder, spleen, thoracic lymphatic duct and pancreas. The control unit is configured to turn on the heating elements when detecting acute arrhythmias of the heart, or in the prevention of acute disorders of cerebral circulation, blood flow in organs and body systems. Clothing provides heating of these areas with heating elements up to 42 ° C.

The disadvantage of this clothing is that it does not provide the thermoregulatory needs of all temperature-sensitive zones. Improving the activity of reproductive cells is achieved only when using clothes that have special areas that provide effective thermoregulation of reproductive tissues and organs

Known comfort vest (patent RU No. 79021, 2008), made of fabric and equipped with pockets for heat-cold storage elements, and heat-cold storage elements are made of cotton fabric and filled with wool of merino sheep, previously washed with water infusion of roots and leaves of male fern and sprayed with an aqueous solution of colloidal silver.

The disadvantage of this device is the low efficiency of using heating elements due to the small local heat transfer from them, which leads to uneven heating of the body and, as a result, uneven blood supply, and therefore, the likelihood of decompression sickness increases.

Known electric heating kit "Penguin", including an electric heated vest, slippers, cord and three pairs of low-voltage connectors. A person is heated by eleven electric heating elements mounted in a vest and slippers. The elements are tapes of electrically conductive fabric in insulation of polyethylene and connected in parallel (Handbook "Personal Protective Equipment" edited by SL Kaminsky. Publishing House "Chemistry", 1989, p. 163).

However, the known electric heating complex is unreliable in operation due to the presence in the design of the heating element of a large number of docking units. In addition, the implementation of electric heating elements as a whole with clothing worsens the conditions for monitoring technical parameters and maintenance during operation.

The closest analogue is the design of heat-protective clothing (patent RU No. 2177236, 2001), made in the form of a vest, the main details of which - the back and shelves - are connected to each other by stitching only at the shoulder seams, while the clothing contains fixation devices placed on the edges of the sides and the lower parts of the side edges of the back and shelves, and the heat-insulating inserts having the shape of a rectangle and made in the form of multilayer packages of materials are attached by tuning on the surface of the main parts in horizontal rows in the form of separate compartments with vertical gaps between them, and horizontal sections between them are provided with horizontal sections without them, vertical gaps between the inserts are made in the form of wings with vertically placed cords and clamps at the ends, and multilayer bags are formed by two layers of down-proof material with a feather mixture between them.

The disadvantage of this design is that when weather conditions change, it is necessary to manually change the distance between the heat-insulating inserts and there is a difficulty in maintaining this distance during operation, the closure of the structure is regulated by means of fixation in the middle of the shelf and the side edges of the parts, which creates difficulties in operation when performing special tasks .

The objective of the utility model is: ensuring normal operation at low temperatures, increasing the working time of a specialist without risking his life in conditions of low ambient temperatures, increasing ease of use, reducing the fire hazard of heating elements, increasing the efficiency of a heating vest.

The technical result consists in eliminating the imbalance in the temperature balance of heating.

The technical result is achieved by the fact that a heating vest containing a back and a shelf connected to each other by means of fixation located on the shoulder edges, sides of the sides and the lower parts of the side edges of the back and the shelf, flexible heating elements having the shape of a polygon and made in the form of multilayer packages inserted into the chest and back parts of the heating vest from the inside, and flexible heating elements are made of wire made of polyester threads with resistive spraying Yebra, with installed temperature sensor, the heating power is provided from the vest batteries connected by wires to the flexible heating elements and connected to the heating control unit with button controls heating modes.

More specifically, the task is solved by the fact that:

a) heat transfer is increased with the help of weakened insulation in temperature-sensitive zones, while the insulation is weakened in places that are not protected by fat, to improve the response to increased metabolism by demand and to enhance heat transfer, for example, through conduction and radiation to the surface of the skin;

b) providing enhanced steam exchange through special ventilation of temperature-sensitive zones with the flexibility to quickly intensify heat production by improving steam exchange, for example, by transferring excess heated air or moisture, for example, by convection and evaporation of sweat from the skin surface.

The essence of the utility model is that a heating vest, the main details of which are the back and shelves, are connected to each other by means of fixation located on the shoulder edges, sides of the sides and lower parts of the side edges of the back and shelves, and flexible heating elements having the shape of a polygon and, made in the form of multilayer packets inserted into the chest and back parts of the heating vest from the inside, made of wire made of dacron threads with resistive silver sputtering.

Built-in temperature sensors provide automatic temperature control during the formation of a multifunctional and zonal temperature field of a heating vest. The maximum improvement in the activity of human reproductive cells is achieved by placing flexible heating elements, taking into account temperature-sensitive zones of a person.

Therefore, the claimed utility model meets the requirements of novelty.

The heating elements are decentralized, i.e. with offset, which allows you to connect it stepwise, taking into account the creation of zone adaptive heating, and have a built-in system of thermoregulation and thermal shutdown, which completely eliminates the possibility of overheating of a person, even if the operating conditions were violated.

The zonal temperature field of the heating vest makes it possible to take into account the location of temperature-sensitive zones of a person and to provide effective thermoregulation of reproductive tissues and organs.

The essence of the utility model is illustrated in the drawings:

- in FIG. 1 shows a general view of a heating vest;

- in FIG. 2 shows a view of a person with locations for flexible heating elements, taking into account temperature-sensitive zones;

- in FIG. 3 presents the front and back sides of the chest of the vest;

- Fig 4 presents the front and back sides of the back of the vest;

- in FIG. 5 shows a layered diagram of flexible heating elements.

The heating vest consists of a chest 1 and a back 2 parts of a heated vest 3 from the inside, which are inserted with flexible heating plates 4, made of a wire made of dacron threads with resistive silver sputtering, which provides multifunctionality and zonality of the temperature field of the heating vest 3.

The arrangement of flexible heating elements 4 made of a wire made of dacron yarns with resistive silver sputtering for chest 1 and back 2 parts is shown in FIG. 3, 4. In addition to the electric wire made of dacron threads with resistive silver sputtering, temperature sensors 5 are installed in the flexible heating elements 4, which automatically maintain the set heating temperature.

The system of "Velcro" 6 allows you to tightly fix on top of the outer clothing chest 1 and back 2 of the heating vest 3.

The heating vest 3 is powered by lithium-ion polymer rechargeable batteries 7, made in the form of a flat block, which is placed in the pockets 8 of the heating vest 3, to fix the position of the rechargeable batteries 7 in the pocket 8, a valve 9 is used, which is closed with Velcro. All this is placed on top of the outer clothing.

Placing the batteries 7 on the chest side 1 of the vest 3 ensures that the batteries 7 do not interfere with operation. For example, external pockets 8 for batteries 7 may be placed more forward (backward) for convenience. The location of the batteries 7 also provides easy access to them. For example, you can use one hand to easily remove (replace) batteries. It should be noted that the batteries 7 can be placed where necessary.

The batteries 7 are connected by wires to the flexible heating elements 4 and are connected to the heating control unit 10.

Under the clothes is also the heating control unit 10 of vest 3 with a control button for heating modes. Pre-charging the batteries 7 is carried out using a charger from the 220 V network when in a stationary structure. After turning on the flexible heating elements 4, the heating does not work continuously, but only if necessary.

In the heated vest 3 there are provided internal cavities (pockets), closed with Velcro flaps, for accommodating the flexible heating elements 4 in the chest 1 and on the back 2 parts of the heating vest 3. The flexible sections of the heating elements 4 are made of elastic materials with sewn-in heating wires made from dacron filaments with a resistive coating of silver, and are connected to the batteries 7 using switching wires and pads 11.

Flexible heating elements 4 are made of four layers arranged in the following sequence (from top to bottom) in accordance with FIG. 5:

the first layer A - is intended for intense heat transfer to the body, and also provides a snug fit of the heating elements 4 to the heated surface, a sufficiently thin part of the first layer of heating elements provides a minimum thermal gap;

the second layer B is a layer with placed heating elements 4, which can be connected stepwise and in groups, temperature sensors 5 of flexible heating elements 4 are placed on the same layer;

the third layer B is a protective insulating layer with low thermal conductivity and high permeability to thermal radiation;

the fourth layer G - the reflective layer is placed on the outside of the flexible heating element 4. The reflective surface of the layer is directly connected with the material of the insulating layer, for example, by applying a metal foil to the insulating layer by vacuum evaporation. This layer is designed to reduce heat transfer from the heating element to the external environment, with the placement of a ground loop along its perimeter (not shown in the figure).

The use of an adiabatic pad provides heat retention and increases the emission of heat rays by flexible heating elements.

The properties of each of the layers of the flexible heating element 4 together allow us to provide the claimed technical result.

A wire made of dacron yarns with a resistive coating of silver in flexible heating elements 4 is placed mainly horizontally. The horizontal nature of the placement of dacron threads with resistive silver sputtering leads to more efficient heating of a person. In particular, the horizontal placement of resistive silver plating yarns in the flexible heating elements 4 creates a more uniform temperature field than other resistive silver spraying dacron threads. Resistively coated silver lavsan threads are sewn into the inner layer of flexible heating elements 4.

Thus, the heating elements 4 made of lavsan filaments with resistive silver sputtering are not only soft, light and flexible, but also absolutely safe from the point of view of the possibility of electric shock and fire hazard.

The heating vest operates as follows.

A heating vest 3 is worn over clothes.

When voltage is applied to the flexible heating elements 4 of the vest 3, an electric current passes through the Dacron threads with resistive silver sputtering, placed in the chest 1 and on the back 2 parts of the vest 3 in the flexible heating elements 4, they (elements) are heated to the design temperature, thereby the heating element 4 generates heat for heating.

Flexible heating elements 4 of vest 3 during heating provide an optimal temperature field for heating. The tight fit of the heating vest 3 to the outer garment is ensured by means of “Velcro” 6, which prevents heat loss, while maintaining a constant temperature in the clothes.

The decentralized placement of the flexible heating elements 4 provides the possibility of stepwise regulation of the heating of body parts depending on the ambient temperature. Creating a uniform temperature field for heating is carried out by using flexible heating elements 4 of vest 3, which provides multifunctionality and zonality of the temperature field of the heating vest 3.

Upon reaching the set heating temperature of the flexible heating elements 4 of the vest 3, the temperature sensors 5 are activated and the flexible heating elements 4 are turned off, providing multifunctionality and zonality of the temperature field of the heating vest 3.

Thus, the proposed device allows you to ensure the zoning of the temperature field of heating and increase the efficiency of the use of flexible heating elements 4 due to the effective heat transfer from them and increase the heat transfer surface.

The technical and economic efficiency of the proposed device is that the use of a heating vest 3 allows for better thermal contact between the two environments, due to the tight fit of the heating surface to the outer clothing and, accordingly, increase the efficiency of flexible heating elements 4.

The maximum temperature of a flexible heating element made of dacron threads with resistive silvering does not exceed plus 25-28 ° C, and in case of burnout of an electric wire made of dacron threads with resistive silvering, it does not ignite, which increases fire and explosion safety heating vest in general.

The creation of an adaptive temperature field of heating provides multifunctionality and zonality of the temperature field of a heating vest. The core of the heating elements may have a different shape. In flexible heating elements, Mylar with resistive silver coating is laid out in a zigzag or horizontal fashion, using at least two electrical conductors connected in parallel, which increases the reliability of heating during operation.

To regulate the heating of the heating vest, flexible heating elements can be connected stepwise and in groups, depending on the ambient temperature, which significantly reduces the energy cost of maintaining a given temperature and allows the maximum use of the thermal energy of electric heaters for heating.

The increase in efficiency is achieved due to the fact that flexible heating elements 4 are used in the design of the heating vest, which can significantly increase the area of the zonal temperature field, ensuring the creation of a more comfortable human existence in various harsh extreme conditions.

This version of the heating vest 3 is characterized by the mobility of the dressing process due to the use of Velcro fasteners 6. The heating vest is very convenient for forced prolonged exposure to cold. This applies to professions such as divers, drillers, oil workers, gas workers, employees of the Ministry of Emergencies, the State Automobile Inspectorate, military personnel, security guards, and others. The heating vest is also used by extreme sportsmen, hunters, and fishermen.
