Description

Heater electrothermal.

Object of the invention

The invention, as expressed in the statement of The present specification refers to a heater electrothermal that contributes to the function to which a series is intended of advantages and innovative features, apart from others inherent in its organization and constitution, which will be described in detail later.

More specifically, the object of the invention consists of a specially designed electrothermal heater to be applicable in the heating of water with gel that used for washing paint guns, especially in the automotive industry, without this being a limitation.

Background of the invention

As is known, the guns that are used to apply paint, by spraying said paint with the intervention of an air compressor, they have a hole in its nozzle of a very small size, which leaves the painting.

Said hole, for proper operation of the gun, it must be completely clean in each use, in order to avoid its obstruction, which is usually done by applying soapy water or water with washing gel, the cleaning being more effective if said water is very hot, thing which is not always easy to achieve quickly and comfortable.

Moreover, at present, and as reference to the state of the art, it should be mentioned that, on the part of the petitioner, the existence of no other is unknown electrothermal heater that has characteristics technical, structural and constitutive similar to those that advocates the present invention, which is intended to solve The problem described.

Explanation of the invention.

Thus, the invention consists essentially of a electrothermal heater, applicable, as mentioned, especially in the automobile sector, to heat the water with gel that is used in the washing of paint guns.

To do this, the heater is configured as a lightweight and easily manageable device (less than 1.5 kg), constituted by a housing in whose interior, properly coupled to an aluminum plate, incorporates four plates low voltage thermoelectric concretely four cells peltier, working at 12 V each and 6 Amps, having a temperature regulator that allows water to be heated to the desired temperature, between 0 and 100 ° C.

The aforementioned peltier cells, since they are thermoelectric devices characterized by the appearance of a temperature difference between the two faces of a semiconductor when a current flows through it, to compensate thermal expansion of the cold and avoid breakage, are covered with an elastomeric foam thermal insulation band, such such as Armaflex® type.

Likewise, it is important to note that once introduced the plate, to which the aforementioned have been attached plates or cells, inside the housing, it is filled with epoxy resin and closes so that it is fully armored and waterproof.

The heater, for connection to the network, It has a hose internally metal and externally lined to withstand high temperatures, provided at its end of an IP67 connector, also complying with said regulations all the set of the apparatus, since it works submerged in water.

It should be noted that the heater also has of a handle to easily immerse it, which acts, In addition, as protection from the heat source, isolating it from the user's hand

Finally, the heater presents a picture of maneuvers equipped with a timer to control the time of operation and a digital display with the controller temperature, which is properly connected to a NTC sensor that is placed inside the housing, near the plates.

The new electrothermal heater represents, therefore, an innovative structure of features structural and constitutive unknown so far for such end, reasons that together with its practical utility, endow it with sufficient basis to obtain the privilege of exclusivity that is requested.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, is attached herein descriptive, as an integral part of it, of a game of planes, in which with an illustrative and non-limiting nature, represented the following:

Figure number 1.- Shows a view schematic of the aluminum plate to which the thermoelectric plates that incorporates the heater object of the invention.

Figure number 2.- Shows a view schematic of the open housing, showing the plate that incorporates inside as well as the insulation band that covers The thermoelectric plates.

Figure number 3.- Shows an external view of the heater, in which the main parts and elements that you understand.

Preferred Embodiment of the Invention

In view of the aforementioned, and in accordance with the numbering in it adopted, you can see an example of realization of the electromagnetic heater, which comprises the elements detailed below.

Thus, as seen in figures 1 and 2, the heater (1) in question is constituted from a housing metal (2), inside, suitably coupled to a aluminum plate (3), incorporates four thermoelectric plates (4) low voltage, specifically four peltier cells, which they work at 12 V each and 6 Amps (in series at 24 V).

Said plates (4) or peltier cells, for compensate for the thermal expansion of the cold and avoid breakage, they are covered with a thermal insulation band (5).

The housing (2), once the plate is inserted (3), with the plates (4) coupled to them and covered by the band Insulation (5), incorporates an epoxy resin filler (no represented) and is completely waterproof.

For its part, the heater (1), for its network connection, available, connected to the housing (2) and conveniently connected to the wiring (6) to the plates (4), of a hose (7), internally metallic and externally lined to withstand high temperatures, provided at its end with a connector IP67 (8), as well as a handle (9) to immerse it with facility, which also acts as a focus protection for heat, insulating it from the user's hand.

Finally, according to figure 3, it is appreciated Like the heater (1), it has a control panel (10) equipped of a timer (11) to control the operating time and of a digital display (12) with temperature regulator (13), which is properly connected to an NTC sensor (no represented) that is placed inside the housing (2), near the plates (4).

In this way, heater operation (1) consists of submerging the housing (2), holding it by the handle (9) in the water with gun wash gel, connected to the network via connector (8) provided on the end of the hose (7), and, by means of the regulator (13) provided in the control panel (10) indicate the temperature you want to obtain.

Describe sufficiently the nature of the present invention, as well as the way of putting it into practice, not it is considered necessary to extend its explanation so that any subject matter expert understands its scope and advantages that derive from it, stating that, within its essentiality, may be implemented in other forms of embodiment that differ in detail from that indicated by way of example, and which will also achieve the protection that collects as long as it does not alter, change or modify its principle fundamental.
