Oppfinnelsen angår en vegg-varmeventilator med et hus for opptagelse av en vifte og et elektrisk varmelegeme samt av gitre overdekkede tilluft- og fraluftåpninger. The invention relates to a wall heating ventilator with a housing for accommodating a fan and an electric heater as well as supply air and exhaust air openings covered by grids.

Ved varmeventilatorer av denne type er det kjent å anordne radialvifter eller tangentialvifter i huset. Disse vifter er utført som selvstendige byggeenheter og som sådanne omfattet •av varmeventilatorens hus. Bortsett fra at disse vifter nødvendig-gjør en betydelig fremstillingsomkostning for veggvarmeventilatoren, krever de kjente veggvarmeventilatorer også en stor økonomisk om-kostning. With heating ventilators of this type, it is known to arrange radial fans or tangential fans in the house. These fans are made as independent building units and as such are included •in the heating fan's housing. Apart from the fact that these fans necessitate a significant manufacturing cost for the wall heating ventilator, the known wall heating ventilators also require a large financial cost.

Formålet med oppfinnelsen er å tilveiebringe en vegg-varmeventilator med enkel oppbygning og å forbedre luftgjennom-gangen. The purpose of the invention is to provide a wall heating ventilator with a simple structure and to improve the air passage.

Ifølge oppfinnelsen oppnås ovennevnte formål ved at tilluft- og fraluftapningene er anordnet med samme akse i husets front- og bakvegg, og. at det mellom tilluft- og fraluftåpningene i huset er anordnet en aksialvifte'. På' denne måte er det tilveie-brakt en vegg-varmeventilator med rettlinjet luftgjennommatning på tvers av frontsiden og med forholdsvis liten strømningsmotstand. According to the invention, the above-mentioned purpose is achieved by the supply air and exhaust air openings being arranged with the same axis in the front and rear walls of the house, and. that an axial fan is arranged between the supply air and exhaust air openings in the house'. In this way, a wall-heating ventilator has been provided with a rectilinear air feed across the front side and with relatively little flow resistance.

Viftehjulet og tilluft- og fraluftåpningene er hensiktsmessig anordnet koaksialt i forhold til hverandre.. Videre The fan wheel and the supply air and exhaust air openings are suitably arranged coaxially in relation to each other.. Further

er den mulighet til stede å anordne tilluft- og/eller fraluftåpningen akseparallelt på- avstand fra viftehjulaksen, dvs. for-skjøvet i forhold til viftehjulet. is it possible to arrange the supply air and/or exhaust air opening parallel to the axis at a distance from the fan wheel axis, i.e. offset in relation to the fan wheel.

I en ytterligere utførelsesform av vegg-varmeventi-latoren er det i fraluftåpningen anbrakt et luftledegitter som fortrinnsvis er dannet av en ramme og et antall i avstand over hverandre på denne fast eller innstillbart angripende, vannrette lister eller liknende som tilsammen dekker fraluftåpningen forover på luftgjehnomslippelig måte.. Listen kan være avgrenset, In a further embodiment of the wall heating fan, an air guide grid is placed in the exhaust air opening, which is preferably formed by a frame and a number at a distance above each other on this fixed or adjustable attacking, horizontal strips or the like which together cover the exhaust air opening forward in an air-permeable manner .. The list can be limited,

av plane og/eller skråttstilte flater eller være vinkelbøyd over of flat and/or inclined surfaces or be bent over at an angle

delbredder. I en foretrukket utførelse rager viftehjulet fritt dreibart inn i et sylinderavsnitt som strekker seg foran fraluft-åpningens luftledegitter i huset og er utformet med en deldybde av huset. Sylinderavsnittet er fortrinnsvis utformet i ett stykke med luftledegitteret. Fraluften strømmer således inn i det av sylinderavsnittet omfattede område av luftledegitteret, mens det utvendig ved siden av sylinderavsnittet i luftledegitteret oppnås lufttilførselssoner som i forbindelse med den på baksiden anordnede tilluftåpning tilveiebringer gunstige strømningsverdier for vifteluften. partial widths. In a preferred embodiment, the fan wheel projects freely rotatably into a cylinder section which extends in front of the exhaust air opening's air guide grille in the housing and is designed with a partial depth of the housing. The cylinder section is preferably designed in one piece with the air guide grid. The exhaust air thus flows into the area of the air guide grid covered by the cylinder section, while on the outside, next to the cylinder section in the air guide grid, air supply zones are achieved which, in connection with the supply air opening arranged at the back, provide favorable flow values for the fan air.

Endelig er det også sørget for å anbringe varmelegemet i strømningsretningen koaksialt foran eller bak viftehjulet i huset, og å anordne et fritt mellomavsnitt i varmelegemet, i hvilket avsnitt viftemotoren rager inn. Finally, care has also been taken to place the heater in the flow direction coaxially in front of or behind the fan wheel in the housing, and to arrange a free intermediate section in the heater, in which section the fan motor protrudes.
