  • the drainage ring 213 is formed by laminating one or a plurality of outgoing fire rings 2031, and the third grooves 2131 on the drainage ring 213 are aligned to form a gas passage through the gas delivery passage of the gas distribution chamber 204 and the outer flame ring 203.
  • the intake length of the outer flame ring 203 can be adjusted, thereby changing the pressure loss of the gas from the gas distribution chamber 204 into the gas delivery passage of the outer flame ring 203.
  • the amount acts to adjust the intake pressure of the gas delivery passage of the outer flame ring 203 to ensure the stability of the combustion of the exiting fire hole.
  • the lower portion of the inner flame ring 206 is provided with a certain inner flame ring 2062, which is mainly for ensuring that the height of the inner flame ring 206 is suitable for the height of the inner casing inner cavity to meet the fixing requirement.
  • the upper top cover 202 is provided with an axially extending pin hole and is fixed by the pin 201.
  • the large ring air retaining ring 214 hermetically seals the inner flame ring 206 from the upper surface, ensuring that the gas entering the outer flame ring 203 must pass through the draft ring 213.
  • the inner fire hole is formed by alternately stacking the inner flame stop ring 2062 and the inner fire ring 2061.
  • the inner fire ring 2061 and the inner flame ring 2062 are alternately stacked to increase the fire area of the inner fire hole, that is, to improve the combustion efficiency of the inner fire hole, and vice versa, to reduce the combustion efficiency of the inner fire hole;
  • the combustion efficiency of the exiting fire hole is adjusted, thereby effectively achieving a simple adjustment of the combustion efficiency of the burner.
  • the inner fire hole and the outer fire hole share the gas distribution chamber 204 air intake, effectively ensuring that the exit fire hole has sufficient gas replenishment amount, which is an effect that cannot be achieved by using an independent air intake passage to supply air to the outer fire hole.
  • the upper top cover 202 is provided with a safety column 210 for preventing the bottom of the pot from completely sealing the top of the burner.
  • the The safety post 210 is designed as a hollow cylinder that can be directly placed over the top of the pin 201.
  • the intake end of the air inlet seat 209 is connected to the main passage tube 403.
  • the air inlet seat 209 is provided with a retaining ring.
  • the chamfer provided on the main passage tube 403 prevents liquid from penetrating into the air inlet seat 209.
  • the connection gap with the main channel tube 403 prevents rust and prolongs the service life.

Abstract

L'invention concerne une cuisinière intégrée comprenant une chambre de pré-mélange pleine à soufflage d'air comprenant un corps du type meuble (500) comprenant une unité de cuisinière. Une admission d'air (5011) est disposée au niveau de la partie supérieure du corps (500). L'admission d'air (5011) est raccordée à une boîte de collecte d'air. L'admission d'air d'un ventilateur (503) est disposée à l'intérieur de la boîte de collecte d'air et le ventilateur (503) est également raccordé à une conduite d'évacuation d'air (504). Un trou d'installation (302) est disposé au fond d'une cuvette de propreté (301). Un brûleur (200) est disposé à l'intérieur du trou d'installation (302) et assure l'étanchéité du trou d'installation (302). Un support de casserole (100) est disposé à l'intérieur de la cuvette de propreté (301). Le support de casserole (100), la cuvette de propreté (301) et le brûleur (200) forment une zone de combustion de chambre de poêle fermée dans laquelle il est possible d'empêcher l'air d'entrer depuis le dessous, le brûleur (200) étant proche du sommet du trou d'installation (302). Une conduite de gaz est raccordée à une chambre de pré-mélange pleine (211) du brûleur (200) par le biais d'un robinet à tournant réglable. Le robinet à tournant réglable et un dispositif de commande peuvent commander le volume d'air selon les informations d'admission de gaz, de sorte que le gaz et l'air atteignent un rapport logique.
