SK500572023U1 - Kitchen hood with air ionizer - Google Patents

Abstract

A kitchen hood with an air ionizer consisting of a body (1) of the hood, which is equipped with an intake opening (2) of vapors, behind which a fan (3) is arranged for sucking in vapors, and which is further equipped with a cleaning filter (5) and an exhaust opening (6), while the hood is equipped with an ionization unit (7) with an exhaust opening (8) located in the body of the hood (1) to blow ionized air into the kitchen area, and is further equipped with a switching and closing flap (4) for directing the sucked vapors into of the cleaning filter (5) or the intake air into the ionization unit (7) to ionize the air after the heat preparation of the food is finished.

Description

The technical solution concerns a kitchen hood for extracting unwanted gaseous substances (hereinafter referred to as fumes) arising during the thermal preparation of food, equipped with an air ionizer to clean the air in the kitchen space when the process of thermal food preparation is not taking place.

Current state of the art

At the present time, a whole range of kitchen hoods is known, which ensure the extraction of unwanted vapors arising in the process of heat preparation of food from the kitchen area, which are usually located above the stoves. Other hoods usually contain a body with a fan and have intake openings for sucked in vapors and exhaust openings that can bring the filtered air back into the kitchen space through filter media or can be connected to channels that take the vapors away from the kitchen to the outside. Other hoods thus only have a function enabling the extraction of unwanted vapors with the exhaust of the extracted vapors outside the kitchen area or with the exhaust of these vapors after they have been cleaned through the filter back into the kitchen area.

However, the vapors filtered in this way do not sufficiently ensure a comfortable atmosphere in the kitchen.

The essence of the technical solution

The listed shortcomings are largely eliminated by the kitchen hood with air ionizer according to the technical solution, which is put into operation at a time when the process of heat preparation of food is not taking place. This kitchen hood consists of a hood body, in which a fan is placed behind the suction opening to suck in fumes. The absorbed vapors enter the pipe located behind the fan, which is equipped with a switchable shut-off valve.

This switching closing flap is controlled mechanically or, in an advantageous embodiment, electrically or electronically by means of a smart phone, etc., and allows, in its one position, to direct the sucked vapors to the cleaning filter and from it back to the kitchen area or outside the kitchen to the exterior, or in its second position direct the sucked air into the ionization unit located in the body of the hood, while this ionization unit is put into operation only after the end of the heat preparation of the food. In the ionization unit, the ionization of the supplied air is carried out and the air is then taken back to the kitchen through the air outlet of the ionization unit located in the body of the hood. The ionization unit is placed in the body of the hood and then, after switching on, cleans the contaminated air and neutralizes odors, bacteria, pollen and smoke emissions, and then returns the cleaned air back to the kitchen area. The ionization unit is switched on only after the end of the heat preparation of the food and after the end of the hood's basic function, by switching the switching and closing flap to the position for air supply to this ionization unit, preferably at night or when there are no people in the household - air ionization should not be carried out in the presence of people in the kitchen. The ionization unit is powered directly by electric current 230V/50Hz, or 110-120V/60Hz, if this voltage is used or through a transformer.

Implementation examples

Example no. 1

A kitchen hood with an air ionizer according to this embodiment consists of a body 1 of the hood, which is equipped with a vapor intake opening 2, behind which a fan 3 is arranged to suck in vapors, which are then directed from the fan 3 through the switching and closing flap 4 to the cleaning filter 5 and then from it through the air vent 6 into the kitchen area. In the body 1 of the hood, the ionization unit 7 is then further arranged for ionization and cleaning of contaminated air, while it is switched on only after the end of the thermal preparation of food by switching the switching and closing valve 4 to the position enabling

SK 50057-2023 U1 air supply to the ionization unit 7. From this ionization unit 7, ionized, i.e., purified air is directed into the kitchen space through the outlet opening 8 of the ionization unit located in the body 1 of the hood. The ionization unit 7 and the switching and closing valve 4 are controlled electrically, with a voltage of 230 V/50 Hz, while their switching is carried out electronically using a smart phone.

Example no. 2

A kitchen hood with an air ionizer as per embodiment no. 1, with the difference that the vapors are directed outside the kitchen space to the exterior through the exhaust opening 9, and that the switching of the switching and closing flap 4 and the start of the ionization unit 7 is carried out using the electric switch 9 10 located on the body 1 of the hood.

Industrial applicability

The technical solution is primarily usable in the kitchens of households, but also in the kitchens of large-capacity catering facilities.
