That the filter disc (5) with the lid (7) can be removed from the base plate (6) parallel to the inner wall, 2. That the closure cover (7) can be placed on the filter disc with two or more short (12) or long spacers (8) and is secured against falling off, 3. That the telescopic tube with sound insulation (11) is extended on the room side by a funnel (4). 4. That a temperature-controlled heating element (9) is located in the telescopic tube (3) or in the funnel (4).

Description

[0001] This air intake element consists of an outer weather protection hood (1) with a foil non-return valve (2), a telescopic tube (3) with a funnel (4), and a closable inner cover with a dust filter (5). Once installed, the air intake element is concealed behind the radiator. To change the filter, the dust filter (5) is removed laterally from the base plate (7) using the cover (6), and the dust filter (5) is then washed or replaced. After cleaning the dust filter (5), the cover (7) is placed onto the dust filter (5) using the long metal spacers (8) and then slid back onto the base plate (6) until it stops. In case of smog alert, the dust filter (5) is removed laterally using the cover (7), the cover (7) is rotated, and then placed back onto the dust filter (5) using the short metal spacers (12).After the dust filter (5) has been pushed back into the base plate (12) from the side, the air intake opening is practically airtight. An air gap of 20 mm behind the radiator is sufficient for installation. The cover is either magnetically attached or secured to the filter with spring elements (10) to prevent it from falling off. A soundproofing insert (11) reduces noise transmission.

[0002] A hand drill (up to 115 mm diameter) is sufficient to drill the opening for the DN100 telescopic pipe. The telescopic pipe is extended on the room side by a funnel (5), effectively doubling the usable filter area. A temperature-controlled heating element (9) ensures comfort in winter. Project idea: Air intake element for installation behind radiators. My name:

[0003] My name is Peter Moser and I was the manufacturer and developer of the decentralized ventilation system inVENTer. My company, Öko-Haustechnik GmbH, sold approximately 50,000 wall-mounted fans before I sold the company.

[0004] I have previously worked on developing small heat pumps, but without success, as the German supplier market could not provide suitable components (including inverter technology). I would like to sell my idea and assist with its implementation, if desired.

[0005] Advantage for manufacturers • Simple parts

[0006] Disadvantage: • No?

[0007] Advantages for the installer • Inexpensive wall penetration possible through hand drilling

[0008] Disadvantage • During renovation, some plaster must be removed from the edge of the wall opening.

[0009] Advantages for landlords / homeowners • Visually unobtrusive inner panel. The inner panel can be hidden behind a picture when the heater is operating without a radiator.

[0010] Disadvantage: • No?

[0011] Advantages for tenants • Discreet ventilation with heat recovery, lower energy costs when the wall-mounted heat pump with integrated heat recovery (DE202025002886) is used. • Dehumidification of the room air

[0012] Disadvantage: • Cold air intrusion during severe frost, if the air supply elements cannot be mounted behind radiators. • Sometimes dry fresh air in winter Lockable air inlet element for installation behind radiators

[0013] literature DE202016005865U1 DE102014200583A1 State of the art

[0014] Lockable air supply elements for controlled ventilation without heat recovery essentially consist of an outer weather protection hood, a telescopic tube with sound insulation, and an inner lockable cover with an air filter. The air filter is sometimes integrated into the telescopic tube for large wall openings (150 mm diameter). The inner cover adds 5 to 8 cm in height (DE102014200583A1) to provide space for a large dust filter and the locking mechanism. If the air supply element is to be placed under the window, only 15 to 20 mm of space is available behind the radiator. The inner cover according to patent DE102014200583A1 could be installed if the cover were removable from the side. DIN 1946 for controlled ventilation additionally requires a locking mechanism for the cover of the air supply element. This is provided for all decentralized ventilation systems and disc valves.The flat inner aperture (DE102014200583A1) lacks a locking mechanism. QUOTES INCLUDED IN THE DESCRIPTION
