452 943 Den i fig. 2 visade utformningen av skyddsplåten 15 med perforerade och ogenom- släppliga zoner har visat sig ge en sådan styrning av den av fläkten 16 cirkulerade varmluften att en i stort sett jämn temperaturfördelning uppnås i ugnens hela inre. Såsom är känt inom omrâdet bidrar även en periodisk omkastning av fläktens rotations- riktning till det goda resultatet. Det har visat sig lämpligt att styra fläktens reversering på så sätt, att den period, under vilken luftströmmen från fläkten riktas in mot ugnen, är omkring en tredjedel av den period, under vilken luftströmmen går i motsatt riktning. Perioderna har lämpligen en längd av ca en respektive tre minuter. Patentkrav452 943 The design of the protective plate 15 with perforated and impermeable zones shown in Fig. 2 has been found to give such a control of the hot air circulated by the fan 16 that a substantially even temperature distribution is achieved in the entire interior of the oven. As is known in the art, a periodic reversal of the direction of rotation of the fan also contributes to the good result. It has been found appropriate to control the reversal of the fan in such a way that the period during which the air flow from the fan is directed towards the furnace is about one third of the period during which the air flow goes in the opposite direction. The periods suitably have a length of about one and three minutes, respectively. Patent claims 1. Konvektionsugn innefattande åtminstone en vid ugnens ena sidovägg anordnad, reverserbar axialfläkt (16) för cirkulation av varmluft i ugnen, samt en framför fläkten anordnad, luftgenomsläpplig skyddsplåt (15) med en central, genomsläpplig zon flšc), samt en genomsläpplig sidozon (l5a,15b) utefter var och en av skyddsplåtens vertikala sidokanter, varvid ogenomsläppliga zoner (l5d,l5e) är belägna mellan den centrala zonen och sidozonerna, k ä n n e t e c k n a d därav, att den centrala zonen flšcf sträcker sig i vertikalled över i huvudsak hela skyddsplåten och har större utbredning nedtill än upptill.A convection oven comprising at least one reversible axial fan (16) arranged at one side wall of the oven for circulating hot air in the oven, and an air-permeable protective plate (15) arranged in front of the fan with a central, permeable zone flšc), and a permeable side zone (l5). , 15b) along each of the vertical side edges of the protective plate, impermeable zones (l5d, l5e) being located between the central zone and the side zones, characterized in that the central zone flšcf extends vertically over substantially the entire protective plate and has greater distribution at the bottom than at the top. 2. Konvektionsugn enligt patentkravet l, k ä n n e t e c k n a d därav, att den när- mast ugnsdörren (12) belägna sidozonen (l5a) har större bredd än den vid inotsatto kanten av skyddsplåten (15) belägna sidozonen (lSb).Convection furnace according to Claim 1, characterized in that the side zone (15a) located closest to the furnace door (12) has a greater width than the side zone (15b) located at the inserted edge of the protective plate (15).
