Description

Electric warmer with at least one carbon layer

The invention relates to the technical field of electricians, in particular to an electric heating device comprising a carbon plastic (carbon) layer, which has the advantage that the heating device can be used as a single heater or as a main heat source or an additional energy-saving effective heat source according to the characteristics of a heating system of a room (such as an independent house, a day-care center, a hospital, a gymnasium, an office or a factory building and the like).

It is known that residential rooms, industrial plants, individual houses, and the like are heated using electrical equipment and systems. Including radiator formula electric heater, for example: oil or other types of heaters using liquid as a heat carrier, and fan heaters, convectors, air conditioners and infrared electric heaters for heating air.

The temperature of the shell of the oil radiator can be as low as 60 ℃, indoor oxygen can not be combusted, and the oil radiator has flame retardance and no noise.

The oil radiator has the defects of large capacity and consumption power of 0.5kW to 2 kW. When the radiator is used, it takes a long time to heat the room, so that the equipment is not used, is not efficient, and cannot be used as a main heating device of a heating system. Also, the oil radiator is heavy, requires a large amount of material and is complicated in manufacturing process.

The fan heater has low cost, low efficiency and reliability, high energy consumption, easy ignition, harm to air and incapability of serving as a main heat source for indoor heating.

The power of the warm-air blower (web address: gettoptim. com/uk/teplovetilyator object. html. on 23.3.2018) is 800W to 3 kW.

The fan heater with the power of 2000W can heat a room with the temperature of 20 square meters, and the fan heater must continuously work because the temperature of the room is immediately reduced due to the shutdown, so that the fan heater has low efficiency, the power consumption is increased, and the performance coefficient is low.

In addition, the fan heater is not completely environment-friendly, some bad manufacturers use plastics to manufacture parts, the plastics can release harmful substances at high temperature, and the fan heater is used in a closed room, so that the fan heater has great harm to the health of users.

Since the heating element may be contaminated with inflammable substances such as dust and fabric particles, the apparatus may cause a fire at a high temperature.

An electric convector is also known as a heater,

its disadvantages are high energy consumption and low efficiency.

An electric converter with a power of 1kW can heat a room of 10-12 square metres but cannot be used as a main heat source. The electric converters cannot be used to build heating systems because of their high energy consumption and high material costs, which results in high costs of the created systems.

The air conditioner with the heating function has low efficiency, large energy consumption, high price, complex design and limited use according to the climate conditions.

The consumed power of the air conditioner is generally 1.6kW to 7 kW. Some air conditioners consume 9kW of power.

When the air conditioner is used for indoor heating, the indoor temperature is reduced in a short time due to the shutdown, so the air conditioner needs to be started for a long time, namely: the air conditioner should be continuously operated for heating, thereby resulting in high energy consumption and high operation cost.

In conclusion, the air conditioner is used as a main heating device, and has the advantages of high energy consumption, high cost, low reliability and low efficiency.

The infrared electric heater is also a well-known heater (http:// lovet-ingenera. com/otoplenie/radiator-oboglev/kak-vybrat-karbonovyj-obogrevatel. html, http:// aqueo. ru/otoplenie/obogrevali/obzor-nochnykh-obogrevatejj. html, http:// www.teploline.com.ua/infrazeni-obrivai. html), (Ukra utility model No. 44667, IPC H05B1/00, H05B3/00, published in 2009, 10.12.19.19.Ukra utility model No. 115979, IPC 20105B 3/16, published in 7.5.10.9.655, Ukra utility model No. 2011, published in 8.12.12.12.12.7.12.7.25.12.12.12.7.7.25.12.12.12.12.7.7.25.12.12.25.12.12.7.12.12.7.7.7.25.12.12.12.12.12.12.7.25.12.12.12.12.7.7.7.7.12.7.7.7.

The infrared warmer may form a localized heating zone.

The infrared heater may heat the objects located in the room and then dissipate the heat. (https:// ru. wikipedia. org/wiki/% D% 98% D% BD% 84% D% 80% D% B% BA% D% 80% B% D% 81% D% BD% 8B% D% B _% D% BE% D% B% BE% D% B% D% B% D% 80% D% B% D% B% D% 82% D% B% BB% D% 8C, http:// infrasonic-obihrvai/teplov/the-printfile-of-infrarayed-dates html, http:// lovet-ingrener. com/opienever/ogrev-evvbrybrat-isobuy-htyj html)

When used in a small room, the infrared heater is more energy efficient than the above heating apparatus, but it cannot be used as a main heat source in a heating system.

Direct acting infrared warmers have the drawback of not being able to continuously provide comfortable conditions for the indoor user, thus narrowing the user's range.

When the infrared wave directly acts on the human body, because furniture, floor, wall and other article dispel the heat after being heated, the people is in warm district, and on the other hand, under the influence of radiant energy, people self generates heat. It is best to design the warmer as a long wave warmer, but this is not the case, and the warmer may emit medium and short infrared beams harmful to the human body, depending on power, human skin, and clothing worn when heated. This effect is not beneficial and undesirable and is not beneficial to human health, as long as people stay in the sun and feel uncomfortable.

When the warmer is fixedly installed on a ceiling or a wall, the radiation direction of the warmer cannot be changed, and the warmer may radiate a working area (such as a working area of a store cashier, a working area of a production workshop provided with specific installation equipment, and a working area of a limited indoor space where students are located) where the user is located and cannot move, and the user may feel uncomfortable when staying in the working area for a long time, and unforeseen consequences such as health hazards may be caused.

In addition, heating of the indoor contents by the infrared warmer may cause some application defects of the infrared warmer.

Currently, many artificial materials and chemical materials are used for interior decoration. Furthermore, most modern furniture and items are made of man-made, plastic or chemical materials. These materials and articles emit harmful pollutants when heated, which are not good for human health, and especially emit short infrared waves when a high-power infrared warmer is used.

At present, an electric warmer is newly disclosed (RU patent No. 132662, IPC H05B 3/30, published in 2013, 9, 20), which comprises a housing, a heater and a heat dissipation assembly arranged in the housing, wherein the assembly is a volume unit with an inner channel, two film heaters are also used, the two film heaters are arranged in the front wall and the rear wall of the housing and abut against the housing wall and the heat dissipation assembly arranged between the film heaters, a steel plate is arranged above the heat dissipation assembly, and the steel plate is overlapped with the top by 20-30%.

The upper and lower parts of the shell can be provided with openings, and the diameter of the opening at the lower part of the shell is larger than that of the opening at the upper part of the shell.

In addition, the heat dissipation assembly can be designed into a radiator form, and a vertical channel formed by parallel steel plates is arranged in the heat dissipation assembly.

The film warmer comprises a curved resistive heating element located between two flexible, heat resistant, electrically insulating films and having an output connected to a power source. The heating element is a single electrically conductive wire that is bent to form a curvilinear element.

The electric warmer is a convection warmer and has the following disadvantages:

the heating of the air is carried out during the transport of the thin film heater, which, according to its design rules, causes the oxygen in the air to "burn" and evaporate the moisture. The warmer also causes overheating of the air, the heat dissipating components are contaminated by the harmful substances released from the contaminated particles and therefore cannot be used continuously, for long periods of time and at night, and the warmer must not be fixed to a wall, ceiling or other place where the entire room can be heated efficiently and quickly, since the cold air partially dilutes the directional air flow of the warmer circulation and the air does not spread throughout the room. Meanwhile, the warmer has high energy consumption and low efficiency and safety.

Recently, a top-mounted infrared electric heating system (RU patent No. 126098, IPC F24D10/00, published in 2013, 3, 20, 8) has been disclosed, in which an infrared thin film heater is used, which is made of a flexible carbon electric heater element selected according to its similar products.

The overhead infrared heating system comprises a suspended ceiling, wherein the suspended ceiling comprises an angle section bar arranged adjacent to a wall, a supporting arm with a cross section and a decorative suspended ceiling plate, and the decorative suspended ceiling plate is arranged in a suspended ceiling unit, a heat insulation pad, a heat reflection film and an infrared film electric heater. Infrared film electric heaters, each provided with a pin-type plug and socket connector, and an electric wire having a pin-hole type plug and socket connector extending on a support frame so as to connect the thin film electric heaters, are installed on a portion of the ceiling plate, and have a size not exceeding the size of the front surface of the ceiling plate in the unit, and are equipped with a heat reflection film and a heat insulation pad.

The infrared thin film electric heater is designed in the form of a flexible carbon electric heater element.

The heat insulation pad and the heat reflection film are integrated with the Penofol material.

The infrared warmer is designed as a flexible carbon electric heater element, such as HEAT P L US corporation (carbon heating film).

The infrared thin film electric heater (infrared heating film) has the following disadvantages:

one is that the direction of action is reduced to the extent that the users are unable to receive infrared radiation and continue to be heated (at least on the skin), while it also causes undesirable heating of the objects in the room, thereby decomposing and releasing harmful substances, and in addition, it heats the air to a lesser extent than necessary, so that the heater is a low-efficiency, low-safety and high-energy-consumption heater.

For the above reasons, the infrared film electric heater cannot be used as a main heating device of a heating system for houses, apartments, industrial plants, offices, and the like.

Another disadvantage is that the infrared thin film electric heater is inefficient because it is not designed to use a continuous carbon layer but carbon strips spaced apart from each other, which does not maximize the area of the electric heater to increase efficiency.

The invention relates to a novel high-efficiency, energy-saving and safe electric heater, which at least comprises a carbon layer. Due to the novel design, the invention can generate heat with low cost and reduce the electric cost of the support. Meanwhile, the invention also has the characteristics of simple design and manufacture, easy use, easy maintenance and the like.

An electric warmer (accessible to the mains) with at least one carbon layer can solve the above-mentioned problems. According to the solution, the electric warmer comprises an infrared heating film and is made of a metal casing, in which a heat reflecting layer, a heating layer and a ground layer are provided. The heating layer comprises one or more layers of infrared heating films made of a continuous carbon heating layer, a heat reflecting layer is arranged on one side of the heating layer, and on the other side of the heating layer, the front wall of the metal shell of the warmer is positioned behind a grounding layer which can transmit infrared radiation.

According to the scheme, the grounding layer capable of transmitting infrared waves is an outer layer of the infrared heating film or is arranged into a separate layer.

According to an aspect, an electric warmer with at least one carbon layer is provided with a temperature regulator, such as a remote temperature regulator.

According to an aspect, the housing has a front wall, a rear wall, an upper wall, a lower wall, and side walls.

According to a solution, the electric heater with at least one carbon layer is fixed on the ceiling and/or walls, or mounted on the floor.

The technical scheme is characterized by being the basic characteristic of the invention, and the expected technical effect can be realized by setting, such as: high efficiency, energy-conservation, high coefficient of performance, function are perfect etc, especially can realize low-cost heat, high heat dissipation and reduce the electric energy loss, can regard this device as the main heat source of indoor heating alone simultaneously or combine a plurality of warmers to constitute solitary heating system for heating such as house, apartment, industry factory building, office's department to provide the safety guarantee for the user, enlarge the user scope, increase user's quantity.

In addition, the invention simplifies the design and manufacturing process, and has convenient and safe use and easy maintenance.

The basic characteristics of the scheme and the technical effects realized by the characteristics are as follows:

among the electric heater who contains the carbon-layer, the zone of heating include the infrared heating film more than the one deck, in the metal wall of shell was located to the zone of heating, infrared radiation heated the antetheca of shell at first, then heated the remaining wall to effective heating metal, effective heat dissipation, the transmission that the infrared radiation passed through metal component is excluded.

In the room where the warmer is installed, as the metal is heated to a high level, the indoor air is also heated efficiently.

The metal near the infrared heating film is heated to cause the increase of the performance coefficient of the warmer, and because the infrared radiation can not penetrate through the metal, the air convection can be realized and the efficient heat dissipation can be realized only by leading the infrared radiation to the metal layer. Since metal is a barrier to infrared radiation, there is no need to direct infrared light onto items, materials, and users.

Because of the high performance coefficient of the infrared heating film, the high performance coefficient infrared irradiation layer is used as a continuous carbon layer, the high thermal conductivity of metal and the safety thereof, the warmer with high efficiency, safety and high performance coefficient can be produced.

Therefore, in creating a heating system suitable for free standing private houses or high-rise apartments, factory kitchens, the described warmer can be used as the main heat source, wherein the individual heating devices do not have to be in communication with each other, the number and power of which can be designed according to the house, apartment or room, and can be installed on any surface, anywhere, to achieve the most efficient heating.

The warmer is simple in design and manufacturing process, such as: the components are simple and easy to obtain, and the size and the power are not limited. The power of the warmer can be changed by using a plurality of layers of infrared heating films, and the thickness of the infrared heating films is not large, so that the warmer is not thickened obviously.
