Description

The utility model relates to electrical engineering, mainly to the field of heating equipment, namely to convectors used in heating systems, and can be used for heating residential, public and industrial premises.

Known electric convector containing a housing made of thin sheet steel with air inlets located at the bottom and horizontal air outlets located in the upper part of the housing, a front heat-emitting panel, a heating element made of an electric heater (TENA), an electronic thermostat, an arm on the outside of the back for wall mounting, a thermal switch and fasteners, characterized in that the electronic temperature controller consists of a housing, a protective cover, a clamp Strap with labyrinth passages for passing air, electronic circuit board, wherein the thermostat housing with a hermetic plastic transparent viewing screen and leakproof buttons on the front side. (Patent for utility model of the Russian Federation No. 133594, F24H 3/04, publ. 20.10.2013).

The known device is reliable in operation and provides a quick restoration of favorable climatic conditions when cold air flows into the room by equipping it with a built-in electronic temperature controller with the ability to control the temperature, both on the device itself and remotely using the remote control.

The disadvantages of this device are the complexity of the design of the housing and functional elements; large dimensions; the possibility of dust penetrating into the convection chamber during convector operation through air inlets horizontally located at the bottom of the casing, as well as the possibility of dust penetrating into the convection chamber through horizontal air outlets in the inoperative (off) state of the converter.

Known convector containing a housing formed by interconnected front panel consisting of the front, sides, upper and lower sides of the housing, and the rear panel, while the housing has at least one air outlet in its upper part of the front side, and inside the housing at least one heat exchange element is placed, at least one air outlet is closed by a mesh, the cell side of which lies in the range from 1.5 to 5 mm. (Patent for utility model of the Russian Federation No. 139081, F24H 3/00, publ. 04/10/2014).

The advantage of this device is the use of a grid to close the air outlet, which prevents the penetration of dust into the convection chamber. However, the grid is located directly on the inclined air outlet in the upper part of the front side of the housing, which does not exclude the possibility of dust entering the convection chamber through the air outlet inclined holes in the inoperative (off) state of the converter.

The limitations of the device are the design complexity, because the case consists of a front panel consisting of front, sides, upper and lower sides; sufficiently large dimensions; the possibility of dust penetrating into the convection chamber when the convector is working through air inlets located horizontally at the bottom of the casing (i.e. parallel to the floor covering).

The closest is a convector containing a housing made of a front flat panel and a rear volume panel, the space between which forms a convection chamber, an electric heating element made of tubular, equipped with fins and mounted horizontally inside the rear volume panel, an air intake grill located in the lower part of the body, an outlet for the passage of air located in the upper part of the housing, and fasteners. (Patent for a utility model of the Russian Federation No. 141837, F24H 3/04, publ. 06/20/2014).

In this device, the functional elements are fixed inside the convection chamber by means of fasteners, which are made in the form of left and right plastic fasteners, each of which contains slots for fixing functional elements and latches for engagement with the side walls of the convection chamber, which complicates the design and increases its dimensions . In this device, the supporting elements with rollers are fixed in the holes of the left and right plastic mounting cases and are located at an angle protruding beyond the longitudinal dimension of the housing, which also increases the overall dimensions of the device as a whole. The rear volume panel of this device has a box-like structure and forms the side walls of the housing, and the air outlet is closed by blinds located between the front flat panel and the rear volume panel, which prevents dust from entering the inoperative (turned off) state of the converter, but it requires opening the blinds when switched on convector, which can lead to overheating of the converter and failure of the electric heating element when the blinds are closed, for example, when the consumer forgets to open it, especially when the thermostat is in the maximum heating position. The box-like structure of the case leads to the formation of slightly heated zones in the region of the corners of the walls. The air intake grill in the known technical solution is made in the form of a separate part and is located in the lower part of the housing parallel to the floor covering, which leads to large penetration of dust into the convection chamber when the convector is in operation.

Thus, the disadvantages of the known device are: insufficiently efficient convection of the air flow, the complexity and large dimensions of the structure, insufficiently high reliability.

The task solved by the utility model is the improvement of technical and operational characteristics and usability.

The technical result obtained using the utility model is to increase the convection efficiency, simplify and reduce the dimensions of the structure, and improve reliability.

To solve the problem with the achievement of the specified technical result in a known convector containing a housing made of a front flat panel and a rear volume panel, the space between which forms a convection chamber, an electric heating element installed inside the rear volume panel, an air intake grill located in the lower part of the body , an outlet for the passage of air located in the upper part of the housing, and fastening elements, according to the claimed utility model, the rear volume the nascent panel is made trough-like with smooth conjugation of all parts of its single wall, the air outlet is made in the front flat panel, the air outlet grill is installed, installed in the upper part of the body between the front flat panel and the rear volume panel in front of the air outlet, and the air intake grill is made in the form of holes made in the lower part of a single wall of the rear volume panel.

Possible additional embodiments of the device, in which it is advisable that:

- the upper part of the rear volume panel was overhanging above the air outlet, formed by the upper edge of the rear volume panel and the upper edge of the front flat panel;

- the electric heating element was tubular, equipped with fins and mounted horizontally inside the rear volume panel;

- fasteners installed on the rear volume panel were used;

- a thermostat was installed, installed on the side or top on the rear volume panel;

- support elements with rollers were introduced, fixed at the bottom of a single wall of the rear volume panel;

- the maximum distance between the supporting elements was chosen smaller than the longitudinal overall dimension of the housing.

The indicated advantages of the utility model are illustrated by the best embodiment with reference to the accompanying drawings.

FIG. 2 - image of the convector, view of the rear volume panel;

FIG. 3 is the same as FIG. 2, view of the front flat panel;

FIG. 4 is the same as FIG. 2, side view;

FIG. 5 is the same as FIG. 2, top view;

FIG. 6 is the same as FIG. 2, with the rear volume panel removed.

The convector (Fig. 1-6) contains a housing 1 made of a front flat panel 2 and a rear volume panel 3, the space between which forms a convection chamber 4. An electric heating element 5 is installed inside the rear volume panel 3. An air intake grill 6 is located in the lower part of the housing 1. The outlet 7 for the passage of air is located in the upper part of the housing 1. The fastening elements 8 are used to install functional elements inside the housing 1 and fasten the panels themselves and can be selected structurally different, for example Example, it is possible to use bolts, screws, various types of latches, brackets, guide supports, electrical connectors for wires, etc.

The rear volume panel 3 is made trough-like with smooth conjugation of all parts (in the places where the corners are mated) of its single wall. (The trough-shaped form is the shape of a tetrahedral irregular truncated pyramid, the bases of which are rectangles, and the height of the pyramid passes through the centers of the rectangles. Moreover, the faces of the pyramid are smoothly interconnected with each other and with the bases.) The outlet 7 for air passage is made in the front flat panel 2. Introduced an output air grill 9, which is installed in the upper part of the housing 1 between the front flat panel 2 and the rear volume panel 3 in front of the air outlet 7. The air intake grill 6 is made in the form of holes 10 made in the lower part of a single wall of the rear volume panel 3 (Fig. 2).

The electric heating element 5 is made tubular, equipped with fins and mounted horizontally inside the rear volume panel.

In contrast to the closest analogue, fastening elements 8 directly mounted on the rear volume panel 3 (Fig. 2) can be used, therefore, the front flat panel 2 can be practically free from the front of the fastening elements 8 (Fig. 3) or contain their minimum quantity.

In the inventive device, as in analogs, a temperature controller 11 (Fig. 2, 4-6) can be introduced, mounted on the rear volume panel 3 (side or top), while the transverse dimensions of the device due to the implementation of the rear volume panel 3 trough-like do not increase.

Supporting elements 12 with rollers can be inserted into the device, fixed at the bottom of a single wall of the rear volume panel 3 (Fig. 2-6). The device may also have brackets (not shown in FIGS. 2-6) for wall mounting of the converter.

To reduce the overall longitudinal dimension of the convector (Fig. 2, 5), the maximum distance L between the supporting elements 12 is chosen smaller than the longitudinal overall dimension M of the housing 1.

The convector works (Fig. 1) as follows.

The convector is installed in the working position on the floor in a convenient place for heating. Unheated air enters the convector through the holes 10 of the intake grill 6 (Fig. 1, 2), located with an inclination of the relative floor covering due to the trough-like shape of the rear volume panel 3. The electric heating element 5 (Fig. 1, 6) is controlled by thermostat 11 (Fig. 2 4-6) is turned on to a minimum level of heating to remove possible dust particles on the floor. In this case, a minimum level of convection is formed, and solid dust particles, without burning, enter through the air outlet grille 9 (Fig. 1, 3) into the outlet 7 for air passage. In the same way, possible small dust particles are removed from the air outlet grill 9, accumulated in the absence of prolonged use of the convector in a dusty room. Solid and small particles of dust after the passage of the outlet 7 are deposited in front of the front flat panel 2, where the intake of cold air is not performed. If the convector is not used for a short time or is in an un-dusty room, dust does not settle on the air outlet grill 9, since the air outlet 7 (horizontal) is located on the front flat panel 2 and the air outlet 9 is inside the convector between the front flat panel 2 and the rear volume panel 3 in front of the outlet 7. In addition, to prevent dust from entering the air outlet grille 9 even in a sufficiently dusty room allows the option in which the top Thread portion of the rear panel 3 is made of bulk overhanging the outlet opening 7 for the air passage (Figs. 1, 3), formed by the upper edge of the rear panel 3 and the bulk upper front edge plane of the panel 2.

Then, the thermostat 11 increases the heating level of the electric heating element 5. In the convection chamber 4, the air is heated, its volume increases, excessive pressure is created, and the heated air flow through the air outlet grill 9 exits the outlet 7 with force.

Thus, they increase the reliability of the functioning of the structure and eliminate the ignition of dust.

To improve convection, the volume panel 3 is made trough-like with smooth conjugation of all parts of its single wall, and the air outlet 7 is made in the form of a gap between the upper edge of the front flat panel 2 and the front upper edge of the rear volume panel 3 (Fig. 1, 2) . For effective convection, the area of the exhaust duct should not have sharp transitions, and the duct should be quite smooth (this is well known when designing chimneys of furnaces). As can be seen from FIG. 1 and especially from FIG. 2 since the front flat panel 2 is located in one plane, and the rear volumetric panel 3 is made trough-like, then in the direction from the electric heating element 5 to the outlet 7, the air exhaust channel first has the same U-shape with a flat rear surface and inclined lateral sides, smoothly conjugated, and further the same U-shape, but with a gradual smooth decrease in the height of the U-shape and a gradual smooth increase in the width of the U-shape, thereby ensuring the same airflow area water channel. And since the air outlet channel in the rear volumetric panel 3 is formed from a single wall with smooth conjugation of all its parts, there are no sharp transitions relative to the initial dimensions of the area of the air outlet channel towards the outlet 7.

The simplification and reduction of the dimensions of the structure is directly noticeable from the diagram and the presented images of the claimed device relative to the closest analogue. In addition, the simplification of the design is additionally achieved through the use of fastening elements 8 directly mounted on the rear volume panel 3 (Fig. 2, 4-6). To further reduce the dimensions (Fig. 3, 5), the maximum distance L between the supporting elements 12 is chosen smaller than the longitudinal overall dimension M of the housing 1 (the supporting elements 12 in the longitudinal direction do not protrude beyond the housing 1, and this convector dimension is determined by the longitudinal dimensions of the front flat panel 2 and rear surround panel 3).

The international standard ISO 9241-11 defines "usability" as the degree to which a product can be used by certain users in a certain context of use to achieve certain goals with due efficiency, productivity and satisfaction.

The term "usability" can be regarded as a synonym for the word "ergonomics" with the difference that the latter determines the minimum of specific physical efforts when using a thing, and the first - the final total degree of convenience, a measure of the intellectual effort necessary to obtain useful qualities of this thing and the speed to achieve a positive result when managing it.

As shown above, the improvement of "usability" is directly manifested in the design (flat front panel, ease of operation) and in its operation (dust removal, horizontal direction of the heated air stream, multi-mode).

The most successfully declared convector is industrially applicable for heating residential, public and industrial premises.
