Description

DK 180793 B1 1 A kitchen installation for use in exhausting kitchen fumes and a structure and building comprising said kitchen installation Field of the invention — The present invention relates in general to the field of kitchen installations. More specifically the present invention relates in a first aspect to a kitchen installation for exhausting cooking fumes from a kitchen. In a second aspect the present invention relates to a structure comprising a kitchen installation according to the first aspect of the invention.

In a third aspect the present invention relates to a building comprising a kitchen installation according to the first aspect of the invention or comprising a structure according to the second aspect of the invention.

In a fourth aspect the present invention provides a use of a kitchen installation according to the first aspect of the invention for removing cooking fumes during cooking.

Background of the invention Within the field of cooking and kitchens, it is customary in modern homes to provide for exhaustion of cooking fumes originating from cooking food. By removing cooking fumes originating from cooking, moist air and particles of grease can be removed from the interior of a kitchen, thereby avoiding moist and grease deposits on various surfaces in the kitchen. Moreover, in recent years it has been found that the process of broiling meat will lead to formation of unhealthy compounds which in certain instances are carcinogenic. Such carcinogenic compounds may be spread as particles in the indoor air in the kitchen. Accordingly, providing adequate ventilation in the area above a stove or an oven in a kitchen — will imply a healthier indoor climate. Such ventilation is conventionally provided by means of a fume hood.

It has been a conventional belief that in order to provide adequate exhaustion of fumes originating from cooking food, the fume hood has to be oriented horizontally above the stove so that the fumes originating from cooking food enter the fume hood in an upward direction.

Therefore, most installations for exhausting of cooking fumes from a kitchen are in the form of a fume hood comprising a horizontally oriented box shaped element extending from a wall at a position above a stove.

, DK 180793 B1 A ventilator in the fume hood provides for creating low pressure in the channel leading fumes away from the fume hood, thereby constantly sucking out air and hence fumes originating from food being cooked on a stove.

Some fume hoods comprise a drawer which can be retracted from the housing defining the contour of the fume hood.

Thereby the position of the area through which fumes are being exhausted can be changed.

Accordingly, conventional fume hoods take up a not insignificant amount of space and thereby presents an unaesthetic appearance.

The company Thermex discloses on page 13 in their product catalog titled "Thermex Design- line 2011/2012” a kitchen installation for exhausting cooking fumes from a kitchen.

The kitchen installation named Integra comprises a wall mounted front panel comprising a through-going channel which leads to horizontal flow channel making a bend in a vertical direction.

The flow channel is arranged within the wall onto which the front panel is mounted.

An external motor provides for suction of air through the flow channel as well as the through- — going channel in the front panel.

The Integra installation also comprises a filter.

This document, however, does not disclose that the filter is arranged at an inclined orientation.

Thereby only a non-optimum efficiency of air flow through the flow channel and the through- going channel in the front panel, as provided by the external motor, is attained.

Therefore, there exists a need for a kitchen installation which provides for efficient exhaustion of cooking fumes and which is having a less clumsy and hence more aesthetic appearance.

It is an objective of the present invention to provide a kitchen installation for exhausting cooking fumes from a kitchen having a simplified visible design and hence a more aesthetic appearance without compromising fume exhaustion efficiency. — Brief description of the invention These objectives are fulfilled according to the first, the second, the third, and the fourth aspect of the present invention.
