Description

[0001] Technical field

[0002] The utility model relates to heating devices, more specifically to devices with forced convection, designed for targeted heating of rooms of any purpose and creating a thermal curtain effect; preferably installed in a window or doorway.

[0003] Technology Level

[0004] Convectors with forced ventilation are known, in which a fan provides effective forced air convection with adjustable speed. For this purpose, the casing is equipped with grilles or diffusers, allowing the flow of hot air to be directed throughout the room. In particular, a convector is known that has a casing containing a heating unit, enclosed in a casing and insulated from the casing, and an air supply unit. Temperature sensors are installed inside the casing of the heating unit on the side of the air supply unit. High and low voltage inputs are located in one of the casing walls (RU patent No. 2343364, IPC F24H 3 / 04, published January 10, 2009).

[0005] A disadvantage of the well-known convector is that the hot air flow directed forward essentially fails to reach the window surface. When the window fogs up, which typically occurs when humidity inside the home is very high and / or outside temperatures are low, the heating unit cannot clear the glass of condensation.

[0006] Also known is a convector comprising a housing with vertically oriented front and rear panels, air intake grilles located in the lower part of the housing and air outlet grilles located in the upper part of the housing, a heating unit located with the possibility of interacting with the air flow in the lower part of the housing above the air intake grilles (patent RU No. 93943, IPC F24H 3 / 04, H05B 3 / 28, A61L 9 / 22, published 10.05.2010).

[0007] A known profile for fastening a double-glazed window unit in a window opening (RU patent No. 229197, IPC E06B 3 / 67, published September 25, 2024) addresses the issue of heating the glazing zone by installing a heating pipe from the room being heated. For this purpose, the slope is fitted with mounting elements spaced along the length of the mounting and stop clips with removable clamps, into which the heating pipe (from the heating system) is inserted. The pipe is secured in the clips at a distance from the slope surface, creating a zone of heated air around the pipe. This zone is covered by a cover with a U-shaped cross-section. Gaps are provided between the slope and the edge sections of the cover, allowing air heated by the pipe to escape and rise.

[0008] The disadvantage of the known solution is the low efficiency of heating the glazed area of ​​the window due to the lack of forced supply of warm air to the window surface.

[0009] A known floor-mounted convector, traditionally installed near windows or glass doors, comprises a housing containing a heat exchanger. The housing has a top grille, side, front, rear, and bottom walls, with the heat exchanger located within the housing, creating air spaces between the heat exchanger and the housing walls. A fan with a flare directed toward the heat exchanger is installed in one of the side air spaces within the casing (RU Patent No. 180413, IPC F24H 3 / 06, F24D 3 / 16, published June 13, 2018).

[0010] A disadvantage of the well-known convector is the limited heat exchange between the heat exchanger surface and the air in the heated room due to the large outlet area and the lack of directional heating. In-floor convectors are also difficult to clean, easily become clogged, and, as a result, result in inconsistent heat output and low reliability.

[0011] Disclosure of the essence of the utility model

[0012] The objective of the utility model is to create a reliable and efficient convector for heating rooms with a large area of ​​glazed windows, with a compact design.

[0013] The technical result is to increase the efficiency of heating a room by creating a convector for heating rooms with a thermal curtain function.

[0014] The specified technical result is achieved in that the directional heating convector contains a box-type housing, on the front panel of which a cover is installed, inside the housing there is a heat exchanger and fans, while, according to the utility model, along the side of the housing there is a slot diffuser with the possibility of directed air release in a direction perpendicular to the front panel of the housing, while along the opposite side of the housing there is an air intake slot opening.

[0015] In addition, according to the utility model, the heat exchanger is made in the form of a water heating battery, while in the cover of the housing there is a chamber for distributing the air pumped by the fans with an opening in the end part for the passage of air into the slot diffuser.

[0016] In addition, according to the utility model, the heat exchanger is made in the form of an electric heating element.

[0017] In addition, according to the utility model, the convector has a vertically oriented housing.

[0018] In addition, according to the utility model, the number of fans is selected depending on the length of the device.

[0019] In addition, according to the utility model, the front panel of the case has a beveled corner.

[0020] The declared convector is designed for installation in an opening in a wall (window or door) and simultaneously performs the function of a convector capable of heating large rooms, and the function of an effective thermal curtain for heating extensive glazing.

[0021] The convector's compact design fits easily into a window opening, for example, without reducing natural light. Thanks to a slot diffuser with a directed air outlet perpendicular to the front panel, the unit generates a warm air flow along its entire length, which not only prevents condensation from forming on the window glass but also provides reliable protection from cold draughts.

[0022] The air intake opening is large enough to avoid significant fan resistance in the suction zone. When using a hot-water heating system, the air expelled by the fans first enters the forced-air distribution chamber, where it is distributed along the entire length of the convector and exits through a slot diffuser.

[0023] Due to the air exiting through a narrow slot diffuser and its relatively high velocity, it forms a unique jet. When released near a flat surface, such as a window, it adheres to it and can travel quite a distance along the window surface.

[0024] Experience has shown that when installed vertically, a convector can block cold airflow through a window several meters wide. During testing of a vertical convector, a horizontal warm air stream generated by a convector placed on a slope immediately adjacent to solid glazing was recorded at a distance of 12 meters. This result was achieved largely due to the Coanda effect, whereby a directed airflow exiting the diffuser tends to deflect toward the window along which it is directed, and under certain conditions, appears to adhere to it. The device is very compact in width (from 175 mm), making it suitable for use on window or door slopes in various renovation and construction projects.

[0025] This ensures a larger area of ​​distribution of the air heated by the device by distributing the air flow over a flat heated surface (for example, a window) and creating a thermal curtain effect, thereby increasing the efficiency of heating the room, while the compact size of the convector and its installation in the wall opening allow it to fit optimally into the design of the room, preserving usable space.

[0026] Brief description of drawings

[0027] The convector is explained with graphic materials, where:

[0031] Fig. 4 - the effect of a thermal curtain in a wall opening.

[0032] The following items are indicated by the positions on the drawings: 1 - housing, 2 - cover, 3 - heating block, 4 - air supply block, 5 - front panel of the housing, 6 - air intake slot, 7 - slot diffuser, discharge air, 8 - heat exchanger, 9 - fans, 10 - distribution chamber.

[0033] Implementation of a utility model

[0034] The directional heating convector comprises a box-type housing 1 with a cover 2, inside which there is a heating unit 3, placed in a casing and insulated from the housing 1, and an air supply unit 4 (Fig. 1, 2).

[0035] A cover 2 is installed on the front panel 5 of the housing 1. An air intake slot 6 is made along the side of the housing 1, while a slot diffuser 7 is made along the opposite side of the housing for directed air discharge in a direction perpendicular to the front panel 5 of the housing 1.

[0036] The front panel 5 of the housing 1 has a beveled corner, due to which the side wall of the housing on the side of the air intake opening 6 is wider than the side wall on the side of the diffuser 7. This shape makes the housing 1 more compact and allows, when installed, for example, in a window opening, not to clutter it and to ensure good penetration of light for natural illumination of the room.

[0037] Figures 1-3 show a heating unit 3 located along the housing and containing a heat exchanger 8, which is designed as a hot-water heating battery. However, the heat exchanger design shown in Figures 1 and 2 is not limiting, since the claimed technical result can also be achieved using an electric heating element as a heat exchanger.

[0038] The air supply unit 4 is also located along the housing and contains a group of low-noise fans 9, the number of which depends on the length of the device. In addition, the number of fans 9 and the fans themselves are selected in such a way that the generated noise pressure does not exceed the maximum permissible values ​​​​and the operation of fans 9 does not create unnecessary discomfort. Fans 9 ensure high heat transfer of the device, as well as active equalization of the temperature inside the room, which helps to avoid the formation of cold or overheated zones. If a hot water heating battery is used, the air supply unit 4 is installed after the heating unit 3 (Fig. 2). In this case, to evenly heat all areas of the opening, the air pumped by fans 9 first enters the air distribution chamber 10 located in the cover 2. The air distribution chamber 10 has an opening in the end section for the passage of air into the slot diffuser 7.

[0039] When using a heating element, fans 9 are installed in housing 1 to provide airflow around the heating element to prevent it from overheating. When using heating element 8 as a heat exchanger, air passing through it is uniformly heated, eliminating the need for distribution chamber 10.

[0040] Maintaining the set temperature and adjusting the fan speed can be accomplished in both manual and automatic modes. Manual adjustment of fan speed is achieved using the smooth fan speed control knob (not shown). Turning this knob simultaneously adjusts the heat output limit and sound pressure.

[0041] For manual control, the device can be equipped with a thermostatic head to control the room temperature. The externally controlled device comes with a thermostat controller, which regulates the power of heating unit 3 to ensure the room climate matches the selected parameters. Additionally, the convector can be connected to a smart home system via WiFi.

[0042] The convector is installed in an opening in the wall, ensuring a minimum clearance (a) from the corner of 15 mm to allow opening of the cover 2 and performing maintenance (Fig. 2, 3). When turning on the convector, the user sets the desired room temperature, for example, 25°C, and the fan speed using the controls. The heat exchanger 8 heats the air entering through the air intake slot 6, which is large enough not to create strong resistance to the operation of the fans 9 in the suction zone. When using a hot water heating battery as a heat exchanger 8 (Fig. 2), the air pumped by the fans 9 first enters the chamber 10, is distributed there along the entire length of the casing 1 and exits through the diffuser 7 with a force set by the fans.

[0043] When the unit is installed on a window slope, the generated air flow creates an effective thermal curtain, preventing cold air from entering the room and eliminating the possibility of condensation on the window surface. The unit is especially effective when mounted vertically (Fig. 4).

[0044] Thanks to its design features, the convector provides a larger area for heated air distribution by distributing the air flow along a flat surface along the window. Using the convector will not only heat the room but also create an effective thermal curtain along the window opening, eliminating condensation.
