Description

The invention relates to the field of hookah smoking and relates to technological equipment kalaudu - a device in which red-hot coals are placed, heating the bowl for tobacco and the tobacco in it.

A traditional hookah consists of a shaft with a channel inside. A bowl (chilim) is installed in the upper part of the shaft, where tobacco or tobacco mixture is poured. The cavity of the chilim, where tobacco smolders, is connected with the mine channel. Specially prepared tobacco is placed in chilim, covered with foil, in which small holes are pierced, and hot hookah coal is placed on top. How many holes there will be in the foil for the hookah depends on how much air and heat will enter the chilim, which means that this directly affects how much the tobacco heats up and how good (light) the draft will be. The number of holes made in the hookah foil depends on the preferences of the smoker and the hookah experience. At the same time, the main task of the foil is to prevent direct contact between tobacco and coal. If there is too much heat, the tobacco starts to burn and an unpleasant aftertaste appears. From the hot coal on the foil, the chilim and the tobacco in it heat up, and during the puff, when hot air passes through the holes in the foil, the tobacco begins to smolder, and the fragrant syrup with which the tobacco is saturated evaporates. It is this process that provides a rich and fragrant hookah smoke. Then this smoke descends through a channel in the mine and passes through the liquid in the flask, as a result of which it is cooled and cleared of some harmful substances.

Despite the simplicity of the design, in order to get the proper result, the use of foil requires a great experience of the hookah operator. The foil, on which the hot coal is placed, should not come into contact with the tobacco in the chilim, it is necessary to maintain a gap of 3-5 mm between them.

From the prior art in the designated area, a bowl for placing coals is known, otherwise - kalaud.

Known technical solution kalaud, patented in the Russian Federation in

as a utility model under No. 205985 (13) U1, A24F 5/00 (2006.01)

(priority date 04/28/2021).

The meaning of this kaloud is to exclude the direct interaction of hookah coals and tobacco.

Features common with the claimed solution are the implementation of the kaloud in the form of an open metal tray, in the bottom of which there is a perforation.

The disadvantage of this solution lies in the fact that the bottom of the kaloud is made single-layer and the hookah coals heat up those parts of the smoking mixture more, over which the coals are directly smoldering.

The closest compared to the claimed solution is a technical solution (see American application for invention No. US2016037825A1 "HOOKAH BOWL WITH ONE-TIME INSERT" with a priority date of 08/06/2014).

The patented design is a prefabricated bowl for a hookah, which has a removable composite insert, consisting of a crucible part for placing the smoking mixture with an open top, a lower part with many holes, a side wall and an upper insert, above which the coal is placed directly. In the upper part of the insert there are also holes for heat from the coal to get inside the insert.

The disadvantage of this solution is a weak heat-insulating barrier between coal and tobacco, made in the form of a thin metal insert, as a result of which tobacco heats up unevenly, burns quickly and unevenly, which significantly increases tobacco consumption and worsens the organoleptic properties of the smoke inhaled during hookah smoking.

Technical result

The technical result of the proposed technical solution is to prevent the burning of tobacco located in the chilim, and in its longer and more uniform smoldering due to the fact that air passing through the kaloud with coals evenly enters the container with tobacco (chilim) while smoking a hookah through a double bottom, in which there is an air layer between the upper and lower layers, in which the hot air drawn in during the puff is mixed and the air temperature is equalized throughout the volume of this layer, as a result of which, due to properly selected perforation in the lower part of the bottom, in chilim along air heated to the same temperature uniformly enters its entire area. For all this, the inventive kaloud has a structure in the form of an open-top container with a double bottom and a wall, in the lower part of which horizontal slots and / or perforations are made to allow air to enter the lower part of the container, which is necessary to maintain the stability of the smoldering process of coals in kalaud. At the same time, the lower layer of the bottom is perforated, and on the outer surface of the upper layer of the bottom there are ribbed sections located opposite the horizontal slots and/or perforations in the wall, intended for coals, and rising above the ribbed sections of the platform with through channels, designed to pass through them heated in kalaude of air. For efficient air circulation inside the kaloud, elevated platforms with through channels are made and located below the upper edge of the wall.

In the kaloud of the proposed design, optimal conditions for smoldering coals are created, while the temperature and volume of air that enters the chilim during puffing, necessary for optimal smoldering of tobacco, are provided by selecting:

- thicknesses of the upper and lower layers of the bottom,

- the size and density of perforations on the lower layer of the bottom, where the parameters of the holes and their location depend mainly on the chilim used in the hookah (chilim with a flat bottom or spherical, chilim with one central passage channel or chilim with several passage channels, which can be located as in the center, and along the perimeter of the bottom of the chilim),

- wall thickness and height,

- heights of platforms with channels rising above the bottom;

- diameters of the channels passing through the platforms rising above the bottom.

The figure shows a section of the kaloud, where:

1 - the bottom layer of the bottom;

2 - perforation made on the bottom layer of the bottom;

3 - wall;

4 - slots and/or perforations in the wall through which air enters;

5 - upper layer of the bottom;

6 - ribbed sections;

7 - towering platforms;

8 - through channels;

9 - air gap between the lower and upper layers of the bottom;

10 - side, passing along the upper edge of the wall.

Description of the proposed technical solution

Kalaud is made in the form of a container open from above, having a double bottom with through air channels in each layer, between layers 1 and 5 of which there is an air gap 9 and a wall 3 with slots and/or perforations 4 in the lower part, through which air enters the kalaud.

The lower layer of the bottom 1 has a perforation 2, and on the upper layer of the bottom 5 there are ribbed sections 6 intended directly for placing coals and platforms 7 towering above them, through which predominantly vertical through channels 8 pass.

The perforation 2 can be either evenly or randomly distributed over the bottom layer of the bottom 1, or located mainly in its central part, or mainly along the edge.

Each ribbed section 6 is located between raised platforms 7 with through channels 8 and a wall section 3, in the lower part of which, opposite these ribbed sections 6, there are slots and/or perforations 4.

In kalaud, it is preferable to make three sections with ribbed surfaces 6, but there can be two or four.

Kalaud can have a structure where all elevated platforms 7 with through channels 8 are made either integrated with the walls 3 or closely adjacent to them, as well as a structure where one elevated platform 7 with through channels 8 is located in the center of the tank, the remaining elevated platforms 7 are made or combined with the walls 3, or closely adjacent to them.

Elevated platforms 7 with through channels 8 are located below the upper edge of the wall 3.

The heated kaloud can be carried either with the help of a grip, for the use of which a side can be made outside the kaloud, in the upper part of the wall, or carried by the handle, which is attached to the wall.

For the manufacture of kaloud, a material is selected that has good thermal conductivity and retains heat for a long time.

When smoking a hookah, smokers inhale smoke, as a result of which a draft (vacuum) is created, as a result of which the air heated in the kalaud is sucked into the chilim, in which, in turn, the process of smoldering of tobacco resumes or intensifies throughout the volume.

EXAMPLE OF PERFORMING KALAUDA

Kalaud is made in the form of a steel bowl with a double bottom. The height of the kaloud is 34 mm, the inner diameter of the bowl is 71 mm, the wall thickness is 2 mm, the thickness of the bottom layers is 3 mm lower and 2 mm upper. Between the layers of the bottom there is an air gap 3 mm thick. On the upper layer of the bottom of the kaloud there are three ribbed sections and four elevated platforms with through channels, while three platforms are located along the wall and are made united with it, and the fourth is located in the center of the bowl. The height of the raised platforms with through holes is 10 mm. In each platform, 3 through channels with a diameter of 4 mm were made. Three horizontal slots located opposite the ribbed sections are made on the wall, above which nine holes with a diameter of 2 mm (perforations) are made. The lower layer of the bottom has a perforation consisting of 54 holes with a diameter of 2 mm, where these holes are evenly spaced along concentric circles radiating from the center.

The wall of the kaloud ends on the outside with a 4 mm high rim.
