Problems solved by technology

Obviously, this dispersion effect introduced into the design and manufacturing process will inevitably lead to a significant increase in production costs. The reason is that the degree of standardization of production is lower than expected—that is, a situation that is familiar to those skilled in the art, so no further work is required. explain

Embodiment Construction

[0016] The present invention is primarily based on the following considerations: as its main purpose is to provide a gas burner which can potentially be adapted to ensure a heat output which can vary over a considerable range, and where such a wide range of heat output should be possible by means of corresponding Since regulation is performed by controlling variables rather than burner size, the solution sought, and thus found, is to define some features of the burner which effectively increase the efficiency of the burner while preferably reducing the space requirement, i.e. increasing the burner of compactness.

[0017] However, in order to achieve the above goals, it is necessary to avoid direct combustion of the gas at the outlet of the gas nozzle, and at the same time set an intermediate premixing zone between the flame zone and the nozzle outlet.

[0018] It has been found that by providing such a premixing zone upstream of the flame zone, ie before the flame zone, an op...

Abstract

The invention relates to a food oven with a premix burner for a steam boiler, said food oven comprising a steam generating boiler, a gas burner, means for generating a forced air flow through and injecting gas into the burner, from the burner extends and is adapted to deliver exhaust gas through the outer duct of the boiler, wherein the gas burner comprises a first inner body, preferably cylindrical, and a second outer body directly communicating with the outer duct and accommodating the first inner body, Thereby forming a pre-mixing area in the hollow space between the two; the outer surface of the first inner body is provided with a plurality of first holes distributed over the entire outer surface, while the surface of the second outer body is provided with a plurality of corresponding second holes. The holes, the second holes are preferably arranged to cover only a single defined portion of the respective outer surface and communicate directly with the outer conduit.

Description

technical field [0001] The present invention relates to an improved oven for cooking food comprising a boiler for generating steam. Background technique [0002] It is well known in the prior art that there are ovens which are suitable for steaming food, i.e. cooking food by steaming, and which, in addition to being able to cook food by any of a number of conventional methods, and which are therefore provided with suitable It is also adapted to subject food to a specific cooking mode by passing a stream of steam into the cooking chamber to fill its interior. [0003] For example, in the German patent application No. 20307161.1 submitted by the applicant of the present invention, the basic features and characteristics of the above-mentioned oven have been described in detail, therefore, reference is made to this application for more convenience and brevity here. [0004] Ovens of this type are also described in detail in other publications, such as European patent EP 1 11692...
