Description

The invention relates to the field of ventilation and air conditioning, namely to clean the air entering the room through the window.

A device is known for natural ventilation of the room, which provides cleaning and regulation of the air flow entering the room. The device is placed in a window and contains a housing with a supply air channel made in the form of a maze with sound-absorbing elements located on the walls. An air filter is installed at the entrance to the channel, and at the exit of the blinds (utility model of the Russian Federation No. 8782, IPC 6 F 24 F 13/18). Precipitation is ensured by a protective grill installed in front of the air filter. Such a device will have a sufficiently high aerodynamic drag due to its design, as well as due to the fact that it should be limited in size, since it occupies part of the window area and reduces the illumination of the room. Therefore, in conditions of natural ventilation, the scope of the device is reduced mainly to micro-ventilation. The installation of such a device in an existing window requires a change in the design of the latter, in particular the removal of part of the glazing or leaf element of the window.

A filtering device for windows and doors is also known, which provides cleaning of the air entering the room through an open window. This device is installed on the outside of the window on the frame. It contains an air-purifying part and a light transmitting part (application for the invention of Germany No. DE 19707218 A1, IPC 6 F 24 F 13/00, E 06 B 7/02). The latter serves to ensure that the overall dimensions of the device as a whole correspond to the dimensions of the frame to which the device is attached, without interfering with the flow of daylight to the window, which is ensured by the manufacture of the light transmitting part from transparent materials. Weather protection is provided by installing a protective louvre grille on the air cleaning part. The device does not need means of regulating the air flow passing through it, since this regulation is provided by the opening angle of the window sash. Installing such a device on an existing window requires minimal changes in the design of the latter, related to the mounting locations of the device.

This filtering device for windows and doors is the closest to the claimed invention in essence and is selected as a prototype.

However, such a filtering device also reduces the illumination of the room with daylight, since part of the surface of the window is covered by an opaque or slightly transparent air cleaning part, and installation on the last protective grill complicates the design of the device.

The basis of the claimed invention is the task of creating a window device for air purification, which would more easily protect the air-purifying part from precipitation and which would have a higher light transmission compared to the prototype by changing the shape of the light-transmitting part, the ratio of the overall dimensions and location of the air-cleaning parts.

This problem is solved in that the window device for air purification, consisting of a light-transmitting part and an air-cleaning part, according to the invention is characterized in that the light-transmitting part is made in the form of an air duct, one end of which is fastened on the outer side of the window block to the frame of the opening for the leaf element, and at the other end directed downward, an air purifying part is installed having a depth in the direction of movement of the air stream less than any other overall dimension thereof.

The implementation of the light-transmitting part in the form of an air duct, one end of which is fixed to the outer side of the window unit to the frame of the opening for the leaf element, and the other side, downward, has an air-cleaning part, which provides the walls of the light-transmitting part from above and from the sides to protect the air-cleaning part from precipitation. This allows you to do without a protective louvre grille, which simplifies the design. In addition, the specified shape of the light transmitting part provides such a position of the air cleaning part, in which it will not face the window with a working surface located on the air flow path, but with one of the side surfaces.

The implementation of the air cleaning part so that its depth in the direction of movement of the air flow is less than any other overall size, with the above position of the air cleaning part increases the light transmission of the device compared to the prototype. This is due to the fact that the air cleaning part will cover a relatively smaller part of the translucent filling of the window, since the area of any of the side surfaces of the air cleaning part, equal to the product of its depth by one of the other overall dimensions, will be less than the area of any of the other outer surfaces of the air cleaning part. The increase in the light transmittance of the device is also confirmed by calculations based on the normative documents methodology given in the textbook "Architectural Physics", ed. N.V. Obolensky. M., "Architecture-S", 2003, p. 110. The maximum result will be achieved when the end of the light transmitting part is directed vertically downward, the working surfaces of the air cleaning part are perpendicular to the plane of the window, and the air cleaning part is located opposite the bars of the window block.

As in the prototype, the transparency of the light transmitting part is ensured by the use of translucent materials for its manufacture. At the same time, from structural and other considerations, individual elements can also be made of opaque materials, in particular, elements for attaching the light-transmitting part to the window unit, elements for installing an air-cleaning part, part of the walls adjacent to these elements.

The air cleaning part of the device can be performed as an air filter for cleaning air from dust and other aerosols, but can also include elements for cleaning air from harmful gases, for example, activated carbon.

According to one embodiment of the window device for air purification, the air purifying part is made as a flat fibrous air filter, which ensures high light transmission of the device due to the insignificant depth of the filter, as well as the ease of replacing or cleaning the filter material in domestic conditions.

According to another embodiment of the window device for air purification, the device is made as a removable, hermetically mounted on the window unit. This option makes it possible to install the device on the windows of existing buildings with minimal changes in the design of window blocks relating to the mounting points of the device, allows you to remove the device from the window.

The drawing shows the proposed device.

The invention will be more clear from consideration of a specific embodiment. The drawing shows a removable window device for air purification mounted on the outside of the window unit. The device contains a light transmitting part (duct) 1, made, for example, of organic glass. The air-cleaning part 2 is located in it (in the direction of the arrow), in this case, frame 3 with filter cloth 4. The window device is hermetically sealed by means of a seal 5 to the frame 6 of the opening 7 in the window unit in which the casement element of the window is installed, in this case transom 8 .

The filtering device operates as follows.

When opening the casement element of the window (vents, transoms) 8, air exchange between the room and the surrounding space will begin. The air passing into the room through the filter cloth 4 will be cleaned of dust, soot, tree pollen and other aerosols. The air exchange will be controlled by the degree of opening of the casement element of the window.

Within the scope and essence of the claimed invention defined by the patent claims, various modifications and additions are possible, which are not limited to the present description of the proposed device and are obvious to specialists in the field to which it relates.
