Description

Field of application of the invention

The invention serves the technical field of air conditioning and ventilation of rooms according to IPC: F24F7 / 013 using wall or window fans which convey air through the wall or the window.

Previous state of the art

Although there are more than 500 patents and utility models of the IPC categories after sighting: E06B7 / 02; F24F7 / 013 and F24F7 / 06 already a variety of active ventilation systems, which can usually be installed firmly in walls, window frames, windows or sash, but these are relatively expensive to purchase and can be, for example. difficult or impossible to realize with tenancy agreements, as in most cases the substance specified on site is damaged or a complete exchange of components is necessary. The hitherto registered flexible systems, without damaging the given structures, are in the view of the instructor in their installation way too complicated, too large or technically misaligned or based on falsely assumed facts and thus effective or ineffective. Standard room fans in tabletop or raised legs found in many households only achieve a placebo effect, but no real cooling in the room. Also, the standard fan placed at the wide open window is limited in its effectiveness, since it confuses the natural convection current in a room and largely by a so-called "flow short circuit" (problematic even in many other systems) only sucks in the indoor air and back in Circulation.

Problem description from the perspective of the applicant

Especially in the hot summer months, many people face the problem of effective room ventilation. Although it is cooler in the evening, the night or in the morning, but many people shy for a variety of reasons, their windows or balcony doors fully open and tilt this only. Reasons for this are often fear of theft / burglary or children in the household for which a completely opened window could become a danger. Similarly, lack of space, penetrating noise, danger to pets, etc ... In addition, many people feel the draft in cross ventilation (for example, two opposite windows open) as unpleasant. The problem is that the room air with the tilt function and the associated so-called night ventilation needed in the summer time three to six hours to be replaced once. For comparison: in winter, the same ventilation method is used for 30-75 minutes. Also missing many households (very often in tenancies in apartment buildings) lack of windows on opposite sides of the house in an apartment, to strengthen the possibility of air exchange in the living room through cross-ventilation.

solution Description

The desired goal is now to strengthen the natural convection current in a room so that the walls, the floor, the ceiling and the furnishings cool down better overnight and thus the warming of the room due to high outside temperatures on the following day remains manageable. The system must be easy to install, affordable in cost, and free from structural alterations to the premises to be usable by the masses. The result is a compact system (roughly similar to an oversized whistle), which has at least one chamber-side suction port (large housing part with integrated technology) and at least one opposite discharge port (narrow, elongated shaft). The housing is provided with an electrically operated fan, which can be selected in a variety of designs (tangential, radial, etc.) in addition to the housing and the housing shape. This system is now attached to the upper horizontal edge of a tiltable sash or door leaf. Thanks to the integrated fan, the warm air of the convection current present in the room, which naturally also reaches the outside via the upper horizontal edge of the tilted window sash or door leaf, is forced out of the room (depending on the fan power). This has the consequence that over the vertical side openings of the tilted window sash or the door leaf, increasingly cooler outside air enters the room and thus the ventilation effect is amplified by the factor of the fan used. Due to the greater spatial separation between inflowing and outflowing air, in contrast to many devices currently on the market, a solution for reducing a "flow short circuit" is also found.

embodiment

The solid housing ( 1 ) of the fan system to be protected (similar to the shape of a whistle) is approximately centered over the housing width with a correspondingly wide and deep groove ( 2 ), which serves for rapid attachment to the upper part of the window sash by attaching the device. This groove can be rigid, depending on the type of window in different product variants or mechanically adjustable with variable groove width ( 3 ), which allows individual attachment to a variety of window types. Stability gets the system automatically through the existing rubber seal, which is mounted towards the outside of the window sash or door leaf and is loaded by the flat support no more than by a standard closure, as well as the weight of the system and on the inside of the sash frame or door leaf adjacent housing wall. This can further increase the adhesion and should be equipped for better vibration damping with its own rubber coating. On the room-side part of the housing leads a power supply cable ( 4 ) to the outside, which by a on this part of the housing or on the cable itself mounted switch ( 5 ) can be interrupted and supplies a mounted inside the housing electric fan. For example, directed obliquely upward, is located on the room side of the large housing part, the suction port ( 6 ), which is provided with a grid or the like to protect the user from contact with the internal fan. On the outlet side, after the groove for attaching, the outflow channel ( 7 ) slightly curved down, so that the blown air is discharged through under the window frame and does not pass through reflection in the interior again. This would be best to improve also a use as a table fan, with an adjustable about the horizontal axis tail realized.

• - Dem Gerät kann ein Ständer (8) ähnlich eines auf dem Kopf stehenden T's in baugleicher Tiefe beigelegt werden. So lässt es sich auch als Tischventilator verwenden. Hier könnte auch eine Ladeeinheit für die weiter unten genannte Akkuversion integriert werden.
• - Um den Sicherheitsgedanken des Systems zu bestärken, kann dieses zusätzlich mit einem auf Erschütterungen sensiblen Sensor und einer damit verbundenen Signaleinheit ausgestattet werden.

Further equipment features for further product development or different product variants:

• - The unit can be equipped with a stand ( 8th ) similar to an upside-down T's in the same depth be settled. So it can also be used as a table fan. Here also a charging unit for the battery version mentioned below could be integrated.
• - In order to strengthen the safety concept of the system, this can be additionally equipped with a shock-sensitive sensor and an associated signal unit.
• Furthermore, a user-programmable time control ( 9 ) increase the convenience of handling.
• - An optional speed control ( 10 ) would help against resonances on the mounting object and for use as a table fan.
• - Equipping with a powerful battery would make the system more flexible and independent of local power sources in the field of application.

Achieved benefits:

The system to be protected allows easy mounting and commissioning within a few minutes. The targeted integration of the device into the given processes of room ventilation makes it possible to use the cooler outside air more effectively and thus achieve a higher efficiency than with conventional devices. It is cost-effective for almost anyone to produce, as well as to bring affordable prices on the market and requires no structural change. In addition, unlike many previous solutions, it provides a real cooling and general improvement of the room climate with approximately the same energy consumption, as the effect of the "flow short circuit" is minimized. Other features include the user's need for security through the vibration sensor with signal unit, the desire for flexibility through the integration of a rechargeable battery, the stand for use as a desk fan, and the convenience of using a speed controller and programmable timing, as well as using a smart home Satisfy control. In addition, the device to be protected offers further application areas, because as well as for the "simple" discharge of hot air on hot summer days, the system can also be used year round for removing moist air from bathrooms and kitchens. In this sense, it could also minimize tobacco smoke as well as other exposures in polluted premises. For these purposes, a suction side filter would be used on the system to protect it from e.g. To protect fats and oils.
