  • the treatment line 220 is more easily accessible for cleaning by the cross section which becomes larger after the constriction 223.
  • a closure arrangement 240 having a closure element 241 is arranged on the treatment line 220.
  • the closure element 241 can be brought into a closing and a passage position, wherein the treatment line 220 is closed in the closed position by the closure element 241, and in the passage position feed 150 can be transported through the treatment line 220.
  • Fig. 1 and 2 show the closure element 241 in the forward position.
  • the closure element 241 designed as a slide can be moved by a translational movement from passage to closing position and vice versa.
  • the treatment line 220 is sealed by the closure element, so that no food can be transported from the reservoir 251 through the treatment line 220 to the collection container 252.
  • closure member 241 By the closure member 241 in the closed position prevents feed 150 from leaking out of the reservoir 251, without this should be treated by steam.
  • the closure element 241 In the closed position, the closure element 241 is arranged at the first end 224 of the treatment line. The closure element 241 is thus preceded in the closed position of the treatment area 22 in the transport direction 221. This makes it possible to clean the treatment line 20, in particular the treatment area 222, without having to remove the food from the storage container 251. This cleaning can z. Example, take place in that steam is performed with closed treatment line 220 via the steam nozzle 230 and the nozzle opening 231 in the treatment line 220 to clean them.
  • the closure assembly 240 is further provided with a resilient member 242 configured as a spring to bring the closure member 241 into the closed position.
  • the closure arrangement 240 is in operative connection with the steam nozzle 230.
  • the closure element 241 can be brought into the passage position by vapor pressure.
  • this operative connection is realized in that a pressure chamber 246 is connected to the steam nozzle 230 via a valve 45. By opening this valve 245, steam may enter the pressure chamber 246, thereby causing the closure member 241 to move from the closed position to the open position against the pressure of the elastic member 242.
  • an overflow line 243 is connected to the space of the elastic element 242.
  • An overflow line opening 244 of the overflow line 243 is arranged on the treatment area 222 of the treatment line 20, so that the treatment area 222 is connected to the space of the elastic element 242 of the closure arrangement 240.
  • This overflow line 243 escapes the gas which is in the control room of the elastic element as soon as it shrinks when opening the closure element 241, (ie the enlargement of the pressure chamber 246), and compresses the elastic element together ..
  • the passing treated food 254 and an eventual (ie not necessarily necessary) underpressure in the collecting container 252 generates a negative pressure at the overflow line opening 244.
  • the steam connection 234 of the steam nozzle 230 is connected via a steam hose made of silicone 13 of a steam generator 20 and a reheater 50.
  • the steam nozzle 230 can thus be supplied with steam via the steam connection 13 and the steam hose, the steam generated by the steam generator 20 and the reheater 50 being supplied in the steam direction for treating a feed 150 via the steam connection 13 through the steam hose of the steam nozzle 230.
  • the steam-conducting section of the steam hose is constant in the steam direction.
  • Pressure chamber storage container collecting container treated food

Abstract

L'invention concerne un appareil électroménager (10), comprenant un générateur de vapeur (20) et un premier contenant de liquide (26) destiné à recevoir un certain volume de liquide, ledit appareil électroménager (10) présentant un réchauffeur (50) qui permet de céder de la chaleur à la vapeur produite par le générateur de vapeur (20), et qui est disposé au moins partiellement dans ou contre le premier contenant de liquide (26) de façon que le réchauffeur (50) soit en communication thermique avec le volume de liquide lorsque ce dernier se trouve dans le premier contenant de liquide (26). La présente invention permet d'obtenir, à l'aide de moyens simples, constructifs et économiques, un appareil électroménager qui permette de produire une vapeur sèche pour la préparation d'aliments ou pour fins de nettoyage. On peut notamment obtenir une réduction des dimensions d'un appareil électroménager pour la production de vapeur sèche. On peut également obtenir de manière simple des résultats particulièrement bons lors de la préparation d'aliments.
