Description

DESCRIPTION

Double flow electric air heater

Technical object of the invention

The present invention describes an electric heater with double flow and independent operation. One of the compartments is prepared so that the air flow is directed towards the feet and the other directs the air flow at the height of the person's body. In this way, the solution in which the best-known heater in the shops in the industry has a mobile deflector that allows directing the flow up or down is improved.

Sector of the technique to which the invention refers

The invention presented is framed in the Sections of Current Necessities of Life and Mechanics, Lighting, Heating, in its sections of Personal or Domestic Objects and Heating, Stoves, Ventilation of the International Patent Classification (IPC), industrially focusing on the manufacture of heating devices and for air conditioning in homes, offices, offices or premises in general.

Background of the invention

With reference to small-sized household appliance-type heating devices, several inventions are registered. Some refer to hand dryers, others to hair dryers, others are intended to heat water very quickly and others fall into the field of those known as fan heaters whose function is to heat small rooms, bathrooms, living room, bathrooms and the like.

Invention ES-0119807 U entitled "An electric heating device" describes a water heater designed to be incorporated into water pipes.

Invention ES-0387456 A1 "Improvements in the construction of electrical heating devices" describes a device for heating liquids.

These are not related to the invention described in this document, which falls under the apparatus known as fan heaters, one of which is the one registered with Utility Model number ES-0254644 U, which basically comprises a fan arranged to generate a forced current of air and a battery of electrical resistances through which the air is forced to circulate, experiencing an increase in temperature.

Other inventions close to that of this document are those registered as ES-1179133 U entitled "Infrared Heater" and ES-1180284 U entitled "Infrared Heater" which also fall within the fan heaters because their operation is based on passing air, in a forced way, by hot elements so that the air current is projected in the room to be heated.

The inventor is not aware of any precedent that applies the solution described in this document, so he considers that it is something new in the current state of the art.

Summary description of the invention

The fan heater of the invention belongs to the family of fan heaters or convector devices whose operating principle is to pass air, driven by a fan, through one or more electrical resistors that heat it.

It differs from halogen heaters whose operation is the emission of infrared radiation by halogen resistors, infrared resistors or quartz resistors. Infrared emitters heat metallic or ceramic surfaces and subsequently, by means of forced convection on the surfaces, heat the air in a room, obtaining less electricity consumption than conventional electric thermo fans.

In closed spaces, both heating devices can be used, while, outdoors or in rooms with draughts, it is recommended to use halogen heaters, since infrared radiation is not affected by air currents and directly affects the surface. area to heat.

The object of the invention is basically specified in an air heater that, in the same casing, contains two heating devices with the particularity that the outlet flow in each of the two sections is emitted in different directions. One of them with a certain inclination upwards and the other sensibly horizontal.

Both sections with their selector and regulating devices can function completely independently, although the inventor's idea is that they do so simultaneously so that the user receives heat both from the waist up and down.

The drawing section, as an inseparable part of the document, and the detailed explanation of an embodiment of the invention describe all the details of the invention, which is a novelty in the field of fan heaters, since none is known that generates double airflow. in different directions.

Detailed explanation of an embodiment of the invention

Double-flow electric fan heater consisting of an electric heater that, in the same casing, incorporates two conventional-type heating devices. In an embodiment preferred by its inventor, the fan heater (1) (Figs. 1 to 4) comprises a casing with its support legs (2), whose internal volume is divided into two parts that allow the circulation of two independent flows of air. For the air intake there is a first grille (6.1) and a second grille (6.2), both located in the upper part of the appliance.

The air flow on both sides is generated thanks to the existence of a first turbine (3.1) and a second turbine (3.2), the same, which, absorbing air from the outside, propel it towards the front part, passing respectively through the group of resistances first. (4.1) and by the second resistance group (4.2) coming out in two different directions.

On one of the sides, which is shown in (Fig.1), the first resistance group (4.1) is arranged, in a vertical position, protected by the casing, near the inclined grill with deflector fins (5.1). The air outlet flow is thus directed upwards.

On the opposite side, shown in (Fig.3), the second group of resistances (4.2) is also placed in a vertical position, facing the vertical grille with deflector fins (5.2). With that arrangement, the exhaust air is directed forward.

This configuration of the fan heater has the advantage that the person who wants to get warm receives hot air both in the upper part of his body, above the waist, and in the lower part, below it.

As the blades of both grills with deflector fins (5.1) and (5.2) rotate simultaneously on their longitudinal axes, it is possible to regulate, within certain limits, the flow outlet angle. To do this, there is an inclined grill orientation flange (9.1) and a vertical grill orientation flange (9.2) that even allow activation with the foot without having to get up.

On the other hand, each of the sides of the fan heater has its corresponding first and second selectors (7.1) (7.2) with at least four positions. One of them It maintains the passage of electric current through all the resistances (4.1) and (4.2) of its group, heating the air to the highest temperatures. In another position, only one or two resistors are loaded, so the temperature achieved is lower. In the third position of the selectors (7.1) and (7.2), the resistors do not receive current, so the generated air flow is at room temperature. In the fourth position of each of the selectors, the stop/start of the apparatus is controlled.

There is also a first regulator (8.1) and a second regulator (8.2), in the corresponding sections of the air heater that are used to control the temperature by means of thermostats.

The two sections of the fan heater (1) of the invention work independently so that the user can choose to use both at the same time or just one of them.

The fan heater is manufactured in various powers, the powers of the two sections being the same or different.

In another form of embodiment, conceived by the inventor, only one turbine is installed with its grid that directs the air flow towards the two sections, thus resulting in an apparatus with a lower manufacturing cost.

It is not considered necessary to make the content of this description more extensive so that a person skilled in the art can understand the scope and advantages derived from the invention, as well as develop and put into practice the object of the same. However, it must be understood that the invention has been described according to preferred embodiments of the same, modifications being possible without this affecting or implying any alteration of the foundation of said invention. In other words, the terms in which this description of the invention has been set forth should always be taken broadly and not limitingly.
