  • the present invention relates to improvements in an enclosed gas fireplace apparatus.
  • a gas kamin usually comprises an enclosure with means for supplying fresh air from 15 the outside, and for releasing into the ambient outside the house the products of combustion.

  • the kamin is usually mounted inside a wall, with its front being visible in the room.
  • the front of the kamin is transparent, being usually made of a heat-resistant glass.
  • the gas Prior to burning the gas, the gas is mixed with air at a predefined ratio. If the ratio is inadequate, this may result in a reduced efficiency, and/or black smoke which
  • the air intake may not preserve the desired ratio.
  • the present invention comprises a gas kamin apparatus having an improved structure and method of operation.
  • the kamin is so devised that, when 20 the kamin is mounted inside the wall, its front part, which is made of glass, is located flush with the wall.
  • the kamin is further improved by having its parts covered in glass, including the inside walls and the gas burner.
  • a special heat-resistant glass is used for that purpose.
  • the kamin includes means for controlling the strength of its flames, while preserving a desired ratio of the gas to air mix. This is accomplished using a new structure gas burner, having several parts which can be separately activated under remote control.
  • the front glass is held in place between the frontal wall of the kamin and a frame located in the kamin. Springs are used to press the frame outward, toward the frontal wall of the kamin.

  • the movable part 32 has holes 321 therein, so that pins 312 enter into the holes, allowing a measure of controlled movement of part 32. 5 This allows the front glass 21 to be inserted into the kamin from the outside (from the room), and the frame will hold the front glass in place between parts 31 and 32.
  • the holes 321 have a diameter of about 14 millimeters (mm).
  • the frame 3 is so devised as to prevent fumes from the kamin from exiting into the room.

  • the glass covering the burner is optional, the burner will function without the glass.
  • the glass reflects the flames and the infrared rays emitted from the flames, to 5 improve the efficiency of the kamin.
  • Fig. 7 illustrates means for controlling the strength of the flames in the kamin, while preserving a desired ratio of the gas to air mix.
  • the burner 4 is divided lengthwise into three
  • Each compartment is supplied with gas from a mains input 61, 15 through separate flow control means 62 and injector 63.
  • each flow control means 62 is of the ON/OFF type and is activated by remote control.
  • each flow control means 62 can control the rate of gas flow therein to change the size of the flames in that row accordingly.
  • Each injector 63 generates the mix of gas and air at the desired ratio.
  • a low flame can be activated by opening only one of the control means 62; a high flame can be activated by opening all the control means 62.
  • the burner is divided lengthwise into three channels. Each channel can be activated independently of the others. Each channel has a row of burning outlets.
  • the glass is reflective, that is the fire is reflected in the glass to improve the burner's efficiency. 5
  • the frame holding the front glass has the following characteristics:
  • An integral frame for the glass is attached to the kamin body using screws, to attach the glass to the kamin body and to achieve sealing.
  • An outer frame is then attached, to hide the integral frame and the screws.
  • the new structure of the kamin with its front glass includes a frame mounted in the 25 kamin body close to its front opening.
  • the frame has an outer fixed part and an inner movable part, wherein the movable part is pushed with springs toward the fixed part.
  • the glass is held between these two parts of the frame.
  • the glass is inserted from the outside into the front of the kamin, by pushing the 30 movable frame with the glass, then pushing the glass upwards. This achieves a glass front of the kamin which is depressed only about 2 mm from the front part.
  • the glass is preferably painted in black or other opaque means, to a width of about 10 mm, to hide the inner movable part of the frame.
  • the glass coating reflects infrared waves, to improve the efficiency of the kamin and to facilitate cleaning the kamin.
  • the new burner structure is economical, wherein only part of the rows can be activated, and still there are flames through all the width of the kamin.
  • the duse (nozzle, jet) system is installed in the kamin body and when the burner is mounted therein in its designated location, the gas injection system is attached to the burner and is synchronized with the 20 burner.

Abstract

L'invention concerne une cheminée au gaz comportant un corps de cheminée et une partie avant en verre. La partie avant en verre est faite d'un verre résistant à la chaleur. Un cadre maintient la partie avant en verre en place. Le cadre comporte une partie fixe extérieure, une partie mobile intérieure et une pluralité de ressorts. Les ressorts exercent une pression sur la partie intérieure vers l'extérieur, en direction de la partie avant en verre pour maintenir cette dernière en place. Un bruleur pour une cheminée au gaz comprend trois canaux dans le sens de la longueur. Chaque canal possède des trous sur sa partie supérieure Le bruleur comprend en outre des moyens de commande d'écoulement de gaz indépendants pour chacun de ses canaux.
