Abstract
ABSTRACT OF THE DISCLOSURE
A frame for a window consists of a plurality of glazed sashes, each glazed sash includ-ing a window pane. There are an outer glazed sash, an inner, room-side glazed sash and an intermediate glazed sash and at least one air channel. The inner glazed sash and the intermediate glazed sash are connected together so as to form a combined assembly capable of installation in the frame as a unit. The assembly includes an electric heating element pro-vided on the room-side window pane of the assembly.
A reflective layer is provided upon a pane surface of the window assembly which surface is situated out-wardly of the heating element to reflect back in a room-side direction heat radiation coming outward from the heating element.

Description
The present invention relates to a window comprising a frame, an outer glazed sash and an inner glazed sash, and a channel for fresh air and/or cir-culating air, the room-side window pane preferably being made as an electric heating element and an outer pane surface is provided with a coating in order to reflect back heat radiation coming outward from the heating element-.~
The object is to provide a new window func-tioning as an air circulation and heating means in aroom and the installation of which is convenient.
In accordance with a particular embodiment of the invention there is provided a window compris-ing a frame, said window being mounted in a wall in a room, a plurality of glazed sashes, each glazed sash including a window pane, said glazed sashes compris-ing an outer glazed sash, an inner, room-side glazed sash, including a room-side window pane, and an intermediate glazed sash, and at least one air channel, said inner glazed sash and said intermediate glazed sash being connected together so as to form a combined assembly capable of installation in the frame as a unit, said assembly including an electric heating element provided on said room-side window pane of said assembly, there being provided a reflective layer upon a pane surface of the window assembly, which surface is situated outwardly of said heating element to reflect back in a room-side direction heat radiation coming outward from the heating element.
Numerous advantages are achieved by the invention. The apparatus combination formed by the inner glazed sash and the middle glazed sash, can handle heating and filtration of incoming air and it further comprises the electrical equipment of the t 3nq3~2 inner window pane which pane functions as a heating element, whereby a window may be used with a conven-tional, existing frame and outer glazed sash, the installation can be carried out by a carpenter with-out special training. The inner glazed sash profile functioning as an air channel promotes the heating of fresh air and the muffling of noise, it is not neces-sary to lead circulation--air into the space between the windows, instead it can be mixed with fresh air inside the glazed sash profile.
The air stream is directed along the surface of the heated pane, whereby the temperature of the fresh air rises. From the point of view of air circulating and heating it is advantageous to direct the stream of air upward into the room. If wished, it is easy to change the stream of air to be blown from the side and~or from up downward. A
blower may be placed in the upper part of the inner glazed sash, where it is protected, for example, from washing water. The blower does not need a glazed sash of its own, in addition, for example, a filter cloth, a one-way valve, regulating means and needed electric wirings may be installed in the glazed sash profile.
The middle glazed sash forms a lid for the filter and the blower, whereby the filter can be easily checked and changed only by opening the middle glazed sash. The profile of the inner glazed sash is preferably in two parts, which makes it easy to install the wirings and operating devices.
In the following the invention will be described with reference to the enclosed drawing, the Figures 1 and 2 of which show vertical sections 1 3'J9302 of a window according to the invention; the embodi-ments differ from each other only for the part of the inner pane functioning as a heating element.
The window according to the invention comprises a frame 1 and an outer glazed sash 2 of normal structure. An esssential novelty is a unit formed by an inner glazed sash 3 and a middle glazed sash 4, which unit preferably comprises, for example, a blower 5 and a filter 6.
Fresh air flows preferably from the upper portion of the outer glazed sash, arrow 7, into the space between the outer glazed sash and the middle glazed sash and into the lower portion 10 of the window through the filter 6 installed between the inner glazed sash 3 and the middle glazed sash 4, arrow 11. In case the locations 9 and 15 of the sealings 8 would change place the filter 6 would correspondingly be in the upper portion of the window, whereby fresh air would advantageously be let in at the lower portion.
Openings 12 are formed in the inner glazed sash 3, through which openings air flows upward along the warmed up surface 13 of the pane and forward via the space 14 into the blower 5, at the location of which the sealing 8 is at location 15, whereby air is allowed into the blower only from the middle space 16 where it has been warmed up.
From the blower 5 the air flows inside the glazed sash, for example, to its lower edge 17, from where it is directed through a slot 18 upward along the surface of the heated pane, arrow 19. A sealing 20 is arranged in the slot 18 which sealing to its configuration interacts with the edges 21 and 22 of the profile in such a way that it can either shut the slot or open it, when it is bended into the space 23.
1 3n93(~2 The room-side window pane 24 comprises an electric resistance known per se, whereby the pane may function as an effective heating element and the pane (surface) 13 next to it in the outward direction S reflects heat radiation preferably selectively.
In the inner glazed sash, preferably in connection with the filter 6, it is possible to install an easily moving-flap 26 which keeps the connection between the filter 6 and the openings 12 clear when air is flowing inward, but closes the connection if the direction of the stream of air for some reason changes to the opposite.
The middle glazed sash 4 covering the filter cloth and the aspirating opening of the blower is hinged from its side to the inner glazed sash 3 preferably in such a way that when opening it the filter and a blower wing will show, whereby it is easy to reach them.
At the point of the blower 5 there is an opening in the inner glazed sash profile for the air stream, and for mixing the inner air or circulation air 28 with the incoming air there is correspondingly an opening 29 and a by-flow opening 31 at the point of the sealing 30 in the profile. The inner surfaces 32 of the inner glazed sash profile 3 may be provided with a sound dampening material.
The heating pane at the room-side may be, according to Figure 1, a single pane or alter-natively, according to Figure 2, a vacuum pane structure 33, whereby the air flow occurs from the outside 16, 34 of a pane 13 provided with a surface reflecting heat radiation selectively.
Alternatively, the surface reflecting heat radiation may be provided in the middle pane or in the outermost pane, both in Figure 1 and in Figure 2.
The object is to provide a new window func-tioning as an air circulation and heating means in aroom and the installation of which is convenient.
In accordance with a particular embodiment of the invention there is provided a window compris-ing a frame, said window being mounted in a wall in a room, a plurality of glazed sashes, each glazed sash including a window pane, said glazed sashes compris-ing an outer glazed sash, an inner, room-side glazed sash, including a room-side window pane, and an intermediate glazed sash, and at least one air channel, said inner glazed sash and said intermediate glazed sash being connected together so as to form a combined assembly capable of installation in the frame as a unit, said assembly including an electric heating element provided on said room-side window pane of said assembly, there being provided a reflective layer upon a pane surface of the window assembly, which surface is situated outwardly of said heating element to reflect back in a room-side direction heat radiation coming outward from the heating element.
