Description

Technical field

The present invention relates to compact electric household convectors using a tubular electric heater containing a resistive heating element as a heating element.

State of the art

The prior art device for adjusting the temperature of an object (see US 2013108253, CL F24F 7/00, publ. 2013 [1]).

A known device for controlling the temperature of an object [1] comprises a housing including an internal cavity, an air intake allowing air to enter the said cavity and openings for releasing heated air.

The known device is equipped with tools that allow you to control the desired constant temperature of the heated room, using temperature sensors that send the necessary signals to the control unit, which directly adjusts the temperature of the air stream leaving the outlet. However, the presence in the design of the device [1] of the indicated means, ensuring the maintenance of a stable temperature in the room, greatly complicates, and therefore, increases the final cost of the finished product, further intended for retail sale.

The heat transfer device is known from the prior art (see US 2013206373, class F28F 13/00, publ. 2013 [2]).

Known heat transfer device includes front and rear panels of circular longitudinal section, which are connected along the borders of the side wall, forming a disk enclosure.

The well-known technical solution [2] is used exclusively for cooling heat-generating devices in systems using built-in reactive heat sinks, in addition, the inventive concept and design features of the technical solution [2] do not imply the possibility of equipping it with heating elements that realize, for example, the effect of convection. Thus, a disadvantage of the known technical solution can be considered a very limited functional scope.

The closest analogue of the proposed technical solution is the electrothermal heating system (see US 2012223065, F24H 1/10, publ. 2012 [3]).

The known technical solution [3] consists of a removable upper and lower plates of circular cross section, which are connected along the borders of the side wall forming the disk casing, with inlet and outlet openings, inside of which there is an electric heating element.

In the known electrothermal system [3], the aforementioned inlet and outlet openings are used for a flow of refrigerant directly in contact with electrical elements to initiate a heating process. Thus, the operation of the known electrothermal system [3] is based on the use of a refrigerant, which, when boiling and during evaporation, removes heat from the element to be cooled, and after further condensation transfers heat to the environment, thereby heating any room.

In addition to using electricity for the functioning of the well-known electrothermal system [3], it is necessary to use coolant, which significantly increases the material costs of operation, in addition, when using the well-known electrothermal system [3] in everyday conditions, an additional drawback will be the need for regular maintenance, which consists in in monitoring the level and properties of the refrigerant, as well as the need for periodic replenishment or complete replacement.

Disclosure of invention

The objective of the invention is the creation of a heating device using a convection effect, having a compact, original design with the manufacture of a housing in the form of a disk (shortened cylinder), while maintaining stable effective heat transfer properties.

The technical result of the invention, which is objectively manifested in the course of its manufacture and use, is the implementation of this purpose, which consists in the execution of the convector body in the form of a disk (shortened cylinder), as well as the enhancement of the heat exchange process.

The specified technical result, realizing the task set before the invention, is achieved due to the fact that the disk convector contains a vertically oriented disk-shaped body of round shape, inside of which a tubular electric heater is installed in its lower part, containing a resistive heating element equipped with a control unit, while the said body has a front , the back and side surfaces, on the lower and upper parts of the housing, respectively, the inlet openings for entering air and vents for heated air.

Preferably, if the control unit is made with mechanical or touch control to adjust the operating parameters.

It is advisable if the means of touch or mechanical control is located on the side surface of the housing.

In one of the preferred embodiments, the disk convector body is equipped with removable legs-supports.

It is preferable if the tubular electric heater is made curved in an arc and equipped with additional resistive heating elements.

It is advisable if the round-shaped disk-shaped case is made expanding downward.

According to one of the feasible manufacturing options, the disk-shaped convector body is made with a uniform increase in depth in the direction opposite to the movement of the heated air, formed by the deviation of the predominantly lower part of the front surface from the vertical axis to the side external to the body and the corresponding side surface section expanded to connect to it .

The implementation of the housing of the proposed convector, consisting of a front, rear and side surface - disk-shaped (shortened cylinder) of a rounded shape, preferably expanding downwards, inside of which a resistive heating element is installed to implement a continuous stable heat transfer process - solves the problem of creating a heat transfer device, the casing of which is made in the form a disk (shortened cylinder), inside of which, in its lower part, a resistive heating element is placed that can create to find the conditions for effective and stable heat transfer, while ensuring the formation of the laminar motion of the heated air stream with reduced resistance and increased temperature, effectively heating the selected room.

In addition, the implementation of the resulting disk case, made in the form of a "shortened cylinder" with a preferably uniform increase in depth in the direction opposite to the movement of the heated air, formed by the deviation of the predominantly lower part of the front panel from the vertical axis to the side external to the case and the corresponding extended to it before connecting to the lower part of the front panel of the housing with a section of the aforementioned side wall - allows you to freely place inside the housing, in parts of it, resistive heating elements of various sizes, shapes and configurations, instantly heating the incoming air flow, which is then free, due to the preferred expansion of the lower part of the body is directed upward towards the outlet openings, while providing additional strengthening of the laminar motion of the heated air stream with an additional reduced resistance and correspondingly elevated temperature, since the cross section of the channel in which the movement is carried out is heated of the air flow relatively broad and without any hindrance, and output channels for heated air as close as possible to the heating element and discharged air does not have time to cool.

- building 1;

- front surface 2;

- back surface 3;

- side surface 4;

- tubular electric heater 5;

- inlets for incoming air 6;

- outlet openings for heated air 7;

- control panel 8;

- support legs 9.

The disk convector comprises a vertically oriented disk-shaped body 1 of a rounded shape.

The disk-shaped casing 1 is made expanding downward, inside of which a tubular electric heater 5 containing a resistive heating element is placed in its lower part.

The housing 1 of the disk convector is equipped with a control unit.

The disk convector is installed on a solid surface, stationary or mobile, using removable tilt-adjustable legs-supports 9 for heating the room and connected to the electric network. The tubular heater 5 continuously and efficiently heats the air flow coming through the inlet openings 6, which is then freely and unobstructed by expanding the lower part of the housing 1, and then freely flows upward, passing through the corresponding channel formed inside the housing 1, while laminar movement is ensured said heated air flow with reduced resistance and elevated temperature, since the cross section of the channel in which the the air flow is relatively wide and made without any obstacles to the movement of the air flow, and the outlet openings 7, into which the heated air flow further enters, are made close to the tubular electric heater 5 and, as a result, the maximum heated air flow is heated, heating the corresponding the room.

The front 2, rear 3 and side 4 surfaces of the proposed disk convector, form a round disk-shaped body 1, expanding downward, inside of which a resistive heating element of a tubular electric heater 5 is installed in its lower part for continuous continuous heat transfer process.

Thus, in addition to enhancing the heat transfer process, while maintaining stable effective heat transfer properties, the invention solves the problem of creating a heat transfer device, the housing 1 of which is made in the form of a disk (shortened cylinder), inside of which, in its lower part, a tubular electric heater 5 s is placed a resistive heating element, which successfully creates the conditions for effective and stable heat transfer, while quickly heating the selected room.
