Description

The invention relates to technological equipment intended for heating tobacco with hookah coals in specialized hookah service establishments.

In particular, the invention considers the design of a device for placing heated hookah coals, regulating the heat of hookah coals or a device for controlled heating of a hookah mixture. Such devices are called kalaud (cloud), heat keeper (Heat Keeper), hotkeeper, alpha hook (Alpha Hookah), block, head - - a device in which red-hot coals are placed, the heat from which heats the tobacco or smoking mixture in the hookah bowl. As a device, it is used not only to place heated hookah coals over a chilim (a cup of tobacco), but also to control the amount of heat coming from these coals towards a chilim filled with tobacco or smoking mixture.

This device, as a rule, consists of a container and a lid, which is regulated by a handle and can be slightly opened. Heated coal is placed inside the container, and the device is placed on the cup. Its peculiarity is that there is no need to obtain complete tightness. Such designs are described, for example, in RU 171519, US 8459269, 9237770. This device has the advantageous advantages of:

- made of metal, it heats up quickly and cools down quickly (it is worth immersing it in cold water and after a couple of seconds it cools down);

- the material does not burn through, is intended for long-term repeated use;

- holds the required amount of coal (2-4 pieces);

- during smoking, you can remove it and cool the tobacco in case of fire;

- the cover allows to control heat and to avoid burning of tobacco;

- due to the fact that coal does not directly affect tobacco, the amount of carbon monoxide decreases.

Thus, a device for accommodating heated hookah coals is known, which is a container with a bottom for accommodating heated hookah coals and with a side wall extending from the bottom, in which through holes are made for supplying air from the external environment into the container, while passages are made in the container to direct the heat flow from heated hookah coals to the area outside the bottom (US 2019320712, A24F 1/30, H05B 3/46, 10/24/2019).

In the known solution, the passages are made in the form of vertically oriented holes in the side walls, which are aligned with the holes in the bottom, which allows the heat from the coals to be directed into the passage and out of it into the smoldering zone of the smoking mixture. Air from the external environment enters the coals through large diameter holes in the side wall of the container. In addition, so that the heat flow does not “leave” upwards (convective rise mode), but, wrapping it up, gets into vertical holes in the side wall, this container is used with a special lid, which is installed on the open edge of the side wall of the container so that between the inner surface of the lid and the end surface of the side wall forms a gap. Also in the lid there are holes for air supply to the cavity of the container.

This decision is accepted as a prototype for both declared objects.

Heating the tobacco or smoking mixture in the chilim determines the quality of the smoke inhaled by the consumer. Three temperature points can be distinguished in different areas of tobacco in chilim. The first point is the outer surface of contact of tobacco with heat from coals, the heating temperature reaches 350-400 ° C (at the moment of puffing). The second point is the temperature inside the tobacco in the container under the outer surface layer, the temperature is 200-240°C. The third point is the middle layer of the tobacco itself, the constant temperature "in cruising mode" is 100-105°C.

In fact, tobacco does not burn in a hookah cup, and when heated, only the moisture from the syrup evaporates. All dense steam is obtained precisely by evaporation, and not by combustion. Given this, there are some important points related to temperature.

The level of smokiness depends on the content of glycerin in tobacco, it begins to evaporate at about 100 ° C. In all modern tobaccos, this component is sufficient, and at the right level of heat, they will smoke well. Tobacco syrup also contains sugar, and at about 168°C it will burn, resulting in an unpleasant burnt caramel flavor. To prevent this from happening, it is necessary to make the heating uniform, the heating temperature of the entire mass of tobacco or mixture within 100-105 ° C is considered sufficient, at which the tobacco wet mass is brought to a boil and steam is formed without unpleasant taste sensations. In particular, this also applies to the surface layer of the mixture in chilim.

When steam is drawn in, a low pressure area is formed in the area under the bottom of the tank, as a result of which the heat from the coals begins to flow through the passages into the area under the bottom (outside the bottom). In this case, air is sucked in both through the holes in the roof and through the holes in the side wall, which leads to the formation of a mixed flow consisting of air and heat heated from smoldering / burning coals. This ensures a decrease in the temperature of the heat entering the chilim with the smoking mixture. The decrease in the temperature of the heat flow occurs due to the transfer of heat from the flow to the walls of the container and heat exchange with fresh air.

The disadvantage of the design of the container lies in its technological complexity. The container is made by precision casting with simultaneous formation of through holes in the side wall. In this regard, the thickness of the walls of the container is different, which, when cooled, leads to the formation of stress concentrators and marriage. A container for burning hookah coals belongs to the category of simple solutions and is usually made by stamping or extrusion / drawing from thin sheet material (duralumin, aluminum or steel). The production of small-sized (approximately 7 to 7.5 cm in diameter) containers by casting moves the product from the category of cheap and simple to the category of expensive and difficult-to-precise products.

In addition, this container cannot be used without a lid. It is the cover that ensures the redirection of the heat flow from vertical movement to counterflow, that is, in the direction opposite to the convective rise of heated air. The entrances to the vertically oriented holes in the side wall are located on the end surface of the open edge of the container, that is, in the zone of direct mixing of hot and cold flows. As a result of heat transfer, the heat flow breaks off the edge of the side wall and exits into the external environment.

The advantage of this solution is that it implements the labyrinth movement of the heat flow, mixing with the flow of fresh air, during the passage of which the temperature of the heat of the flow (coconut charcoal produces a temperature in the range from 600 to 700 ° C, and the smoldering temperature of charcoal during hookah smoking is about 450-500 ° C.) decreases to a level at which, in the process of vaporization from the smoking mixture, there is no burning of the components included in the mixture.

However, in a well-known solution, hookah coals heated to red or red-orange color from all sides are placed on the bottom and kept for some time so that the heat can heat the mixture to the point where steam is released from it. After laying hookah coals in a state of ignition, the bottom is heated, on which these coals lie. The bottom acquires a temperature almost equal to the temperature of heated coals. But the container with coals is located above or on the bowl with the smoking mixture. Therefore, the heat from the bottom is also transferred to the surface layer of the mixture and heats it at an accelerated pace to high temperatures (significantly more than 100°C). The heat flow mixed with air from heated coals leaves the tank in the area of holes along the periphery of the bottom, and the central zone of the chilim is directly heated from the bottom in its central part. Thus, in the known solution, uneven heating of tobacco or smoking mixture occurs: overheating occurs in the central and surface zones of the mixture and heating to nominal temperatures in the periphery zone. This uneven heating is formed due to the fact that the through holes through which the heated flow moves are free passages and do not provide a delay in the movement of this flow or the removal of excess heat.

The present invention is aimed at achieving a technical result, which consists in improving the heat transfer properties of the device by eliminating direct heating of the bottom of the container of this device by passing the flow heated from the heat of the coals through slot-like slots that act as air chokes that slow down the movement of the superheated flow towards the chilim.

This technical result is achieved by the fact that in the device for placing heated hookah coals, containing a base for placing heated hookah coals, in which passages are made to direct the heat flow from the heated hookah coals placed on the base to the area located under the bottom of the tank, the base is made of three plates located from each other, the first of which, which serves to accommodate heated hookah coals, is made on the surface of the central part with through slots with a width of 100 to 350 microns for the heat flow to pass through them into the area under this plate, the second plate is located under the first, attached to it and is made with a central through hole with a diameter not less than the transverse dimension of the central part of the first plate, and the third plate is made solid and attached from below along the periphery to the second plate to form a cavity between the plates for receiving the heat flow passing through the slots of the first plate and with formation at the place of attachment of the third plate to the second plate of openings for the heat flux to exit from the specified cavity.

For this embodiment, the device can be equipped with a grate located on the first plate, made with a handle for laying heated hookah coals over the slots of the first plate. And these through-slots on the first plate can be made radially oriented or arranged in concentric circles or arranged in parallel lines.

In the device, all plates can be made round in plan or square in plan. In addition, the second plate can be provided with a handle.

The specified technical result is achieved by the fact that in the device for placing heated hookah coals, containing a container with a bottom for placing heated hookah coals and a side wall extending from the bottom, in which through holes are made for supplying air from the external environment into the container, while the containers are made passages for directing the heat flow from heated hookah coals to the area located under the bottom of the tank, in the side wall of the tank in the area above the bottom, through holes are made to pass the air flow from the external environment into the tank, the bottom is made of three plates located from each other, the first of which, serving to accommodate heated hookah coals, is made on the surface of the central part with through slots with a width of 100 to 350 microns for the passage of heat flow through them into the area under this plate, the second plate is located under the first, attached to it and made with a central through hole diameter not less than transverse the size of the central part of the first plate, and the third plate is made solid and attached from below along the periphery to the second plate to form between the plates a cavity for receiving the heat flow passing through the slots of the first plate and forming openings at the place of attachment of the third plate to the second plate for the heat flow to exit from the said cavity.

In this embodiment, the device can be equipped with a grate located inside the container on the first plate for laying heated hookah coals over the slots of the first plate. And the through slits on the first plate can be made radially oriented or arranged along concentric circles or arranged along parallel lines.

The side wall or side walls of the container may be circular in plan or square in plan. In this case, the side wall of the container can be connected to the second plate, or the edge sections of the second plate can be bent to form the side wall of the container.

The second plate can be made with a handle, and the side wall of the container is made in the form of a separate part and fixed on this plate.

The device can be equipped with a lid made in the form of a plate connected to the handle or a container turned upside down, repeating the shape of the side wall of the container in plan, while the side wall of the lid or its bottom is connected to the handle. And in the bottom of the lid, through holes can be made for the passage of air from the external environment into the container of the device.

These features are essential and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

According to this utility model, a new design of a device for placing heated hookah coals is considered. The device allows you to regulate the heat of hookah coals and form an adjustable heating of the hookah mixture for uniform and constant heating of the entire mixture in the chilim (cup) with heat, at which the components of the smoking mixture go into a state of steam.

Within the framework of this application, three versions of the device are considered.

In the general case, according to the first embodiment (Fig. 1-6), the device for placing heated hookah coals is a metal base in the form of a flat structure, in which passages are made to direct the heat flow from the heated hookah coals placed on the base to the area located under the bottom containers.

The base is made of three plates 1-3 located from each other. The first plate 1 is intended for placing heated hookah coals on it. On the surface of the central part of this plate, through slots 4 with a width of 100 to 350 microns are made for the passage of heat flow from heated hookah coals through them into the area under this plate. These through-slots 4 on the first plate 1 can be arranged in concentric circles (figure 3) or made radially oriented (figure 4) or arranged in parallel lines or in any other pattern (not shown in the drawings). The pattern of the location of the slots itself is not essential for the formation of the process of passing the heat flow from the coals to the side under the plate.

In fact, this plate is a holder for coals. There are two possible examples of holding hookah coals on this plate. According to the first example, heated coals can be placed directly on this plate over the slots. According to the second embodiment, the device can be equipped with a grate 5 located on the first plate, made with a handle 6 (Fig. 6) for laying heated hookah coals over the slots 4 of the first plate 1. The use of the grate 5 makes it possible to reduce the heating of the first plate by eliminating contact of the coals with plate and ensure natural heat dissipation (convective heat dissipation to the environment). Besides. The grate provides a quick replacement of cooling coals with new heated ones.

The second plate 2 is located under the first one, attached to it and made with a central through hole with a diameter not less than the transverse dimension of the central part of the first plate (on which through slots 4 are made). This plate 2 can be made with a handle to enable removal of the entire device from the chilim at the end of the smoking process (the handle in this case is made of a material with low thermal conductivity). The execution example is not illustratively presented.

The third plate 3 is made solid and is attached from below along the periphery to the second plate 2 to form between the plates 1-3 a cavity 7 for receiving the heat flow passing through the slots 4 of the first plate 1 and forming openings 8 at the point of attachment of the third plate to the second plate (Fig. 2) to exit the heat flow from the specified cavity. Thus, the heat flow leaves the device along the periphery and enters the chilim zone.

Attachment of the third plate can be obtained by welding or forming, when the second and third plates, as well as the elements connecting the plates, are obtained from a single sheet of metal by forming, i. connection of plates can be obtained both in the course of performing a separate technological operation in relation to already finished plates, and simultaneously with the manufacture of the second and third plates from a single workpiece.

All plates 1-3 can be made round in plan, square or polygonal in plan. The form factor of the plates and the device as a whole is not essential for achieving the technical result. The device and wafer form factor information is provided to demonstrate the applicability of the device to various chilim shapes.

A feature of this device is that in it the heat flow from heated hookah coals to the chilim zone passes through slit-like through slots with a width of 100 to 350 microns. Slots of this size in the field of pneumodynamics belong to the type of pneumothrottles used to change the flow rate by creating local pneumatic resistance to the moving air flow. In this case, these air throttles are constant, that is, unregulated, the resistance of which (the value of the flow area, the shape or length of the channel) cannot be changed during operation. Pneumatic throttles are mainly used to control the speed of movement and the speed of filling or emptying containers in order to create time delays and ensure a constant flow rate. The cuts are made using laser cutting. In addition, these slits provide filtration, keeping out large particles of coal and ash, protecting the tobacco mixture in the chilim from harmful impurities. The choice of the transverse size of the slots (width from 100 to 350 microns) is due to the following. At a size of less than 100 microns, passages are formed that. In fact, they practically do not let the heat flow through, but delay it, making the process of smoking difficult. However, this size is limited by the technical capabilities of laser cutting. With an increase in the transverse size of the slots more than 350 μm, a picture of an increase in the flow of the heated flow into the chilim zone is visible. In fact, when the upper limit is exceeded, the slots turn into micro-holes. And taking into account the fact that there are a lot of these cracks, an increase in the transmitted heat to chilim is formed. The choice of the specified range is combined with the fact that it is possible not to control the length of each slot, but to perform the entire central part of the plate 1 with slots, as shown in Fig. 3. Covering the entire central part of the plate 1 with slots is necessary, taking into account the fact that, as a rule, two to four coals are placed on the plate 1 and it is not known how they will be placed on the plate 1 in relation to the pattern of the slots. And the supply of heat flow through the slots passes only in those areas where coals lie.

Considered according to the first variant, the device belongs to the category of open combustion devices, which means free exchange between the surrounding environment and the heat source. In FIG. 4 shows schematically the passage of fresh and heated air flows in the device. In the area where heated hookah coals are placed, a heat flow is formed that flows in all directions in the same way: into the external environment and into the channels of the slots. At the same time, fresh air flows are directed to the hookah charcoal zone to maintain combustion / smoldering coals and mix cold and heated air mass flows. This is a zone of open type of burning/smoldering of coals. Since the process of mixing the heat flow with the flow of fresh air is uncontrollable (the process of oxidative reactions stylishly depends on the type of coal and the temperature and air of the environment), then in the open mode, the heat temperature of the mixed flow can range from 600 to 700 ° C (for coconut charcoal), or be in the smoldering temperature range (for charcoal) of about 450-500°C. Part of the mixed heat flow is convectively discharged into the environment, but the temperature level of burning of smoldering coals remains the same (supported by the process of spontaneous smoldering of hookah coals themselves).

Another part of the heat flow formed in the lower zone of hookah coals from the side adjacent to the slots 4 is forcibly directed through the slotted passages of these slots into the cavity 7 at the moment of smoking (puffing), when a low pressure zone is formed in the cavity. The slots 4 are used as elements for limiting the volume of the heat flow supplied to the chilim and as elements for regulating the rate of drawing the heat flow into the cavity 7.

From the cavity 7, the heat flow through the peripheral openings 8 is supplied to the chilim to the peripheral zone of tobacco or smoking mixture. While in the cavity 7, the heat flow partially gives off part of the heat through the metal of the device, and when leaving the openings, the heat flow is mixed with air from the external environment with a decrease in the total temperature of the flow to a temperature of about 100-105°C. Thus, the heat flow at the outlet of the device is reduced to a level at which, in the process of vaporization from the smoking mixture, the components included in the mixture are not burned out.

Thus, the considered design of the device allows, with open smoldering / burning of hookah coals, to ensure a decrease in the temperature of the heat coming from the coals to close to normalized ones due to the fact that the heat flow goes through a labyrinthine path, on which heat is taken off by the structures of the tank design, and due to the normalized (that is, supplying in constant doses in doses) supplying heat towards the chilim through pneumothrottles.

In the considered embodiment, the smoldering of hookah coals occurs in the mode of open air access due to a freely flowing oxidative reaction with atmospheric oxygen. Limiting the access of air to the smoldering zone of hookah coals allows you to increase the heat by limiting the release of heat flow into the atmosphere.

This mode of operation is illustrated by the example of the second and third embodiments of the device (Fig. 7-11).

A feature of these embodiments is that, unlike the first embodiment, the device is made with side walls, the bottom of which repeats the design of the device according to the first embodiment.

In the general case, the device for placing heated hookah coals according to Fig.7-11 contains a container with a bottom for placing heated hookah coals and a side wall 9 extending from the bottom, in which through holes 10 are made for supplying air from the external environment into the container. Passages are made in the tank itself to direct the heat flow from the heated hookah coals to the zone located under the bottom of the tank. Through holes 10 for passing the air flow from the external environment into the container are made in the side wall of the container in the area above the bottom.

The bottom of this container with side walls completely repeats the design of the base according to Fig. 1-5 (first option).

The side wall of the container for the exemplary embodiment of FIG. 10 is circular in plan and is a hollow cylinder (second embodiment), and for the example of FIG. 7 and 8, the side walls of the container are square in plan (straight or inclined upwards from the bottom) (third version). In this case, different examples of the execution of the side wall are possible. For example, the side wall 9, as a separate part, of the container can be connected to the second plate 2 (Fig. 10) or the edge sections of the second plate 2 are bent to form the side wall of the container (Fig. 8).

The second plate, carrying the side walls, can be made with a handle 11 (Fig. 13), and the side wall 9 of the container is made in the form of a separate part and fixed to this plate with a handle. This will allow you to safely remove the container from the chilim or place the container with coals.

Also, the device can be equipped with a grate 12 (without a handle) located inside the container on the first plate 1 for laying heated hookah coals over the slots of the first plate (Fig. 12 and 14).

When placed, heated hookah coals inside the container rest either directly on plate 1 on parts of the surface with slots in the plate or on the grate on the first plate. Air enters the cavity of the container through the open upper opening of the container (Fig. 9 and 11), providing smoldering coals. The heated air/heat from the coals rises convectively. Tank walls are used to direct the flow upwards and avoid side spread. The process does not have a dynamic character, since most of the heat goes up into the environment. When the heat flow rises up in the area under the coals, a low pressure zone arises, which causes air to be blown through the holes 10. Stable smoldering of the coals occurs.

The dynamic process of moving the flow of heat occurs at the moment of suction of the hookah tube, at which a low pressure zone is formed inside the tube and in the cup (chilim). Since during the convection movement of the heated masses, a low pressure zone is formed, the air from the external environment forcibly begins to flow into the cavity of the tank through the open opening and through holes 10 in the side wall of the tank, providing the process of smoldering/burning of coals on the sides facing the bottom. The air coming from the external environment is mixed upwards by the rising heat flow coming from the coals, and the mixed duct enters the cavity 7, from where the heat flow goes outside, heading for the smoking mixture.

In this case, it should be taken into account that the plate 3 is external and is in contact with the external environment, the temperature of which is significantly lower than the temperature of the heated flow. There is a transfer of part of the heat from the heat to the outer plate, which in relation to the flow is an element of lowering the temperature of the heat flow. The temperature curve of the change during tightening looks approximately as follows. The temperature on the surface of the coals is approximately 600°C; when puffed, the heat flow mixes with air from the external environment through the open top of the container. There is a decrease in the temperature at the inlet in the area of the entrance to the cavity 7 to about 300-350°C. The heat flow enters the air cavity 7, where, due to the heat exchange of the plate 2 with the external environment, the temperature drops to 120-150°C. Then the heat flow exiting through the openings 8 in the plate 3 enters the air gap zone between the container and the chilim (this zone is approximately 5 cm) and is directed to the surface of the smoking mixture (to the peripheral zone), the temperature of which is significantly lower than the temperature of the incoming heat flow. There is a heat transfer between the mixture and the flow, at which the temperature drops to normalized 100-105°C. With each puff, the dynamic process is repeated. According to the rules of smoking, there should be pauses between puffs, at the moment of which the dynamic process smoothly turns into a stationary one without a pressurization of heat into the smoking mixture.

Thus, the considered design of the device allows, with open smoldering / burning of hookah coals, to ensure a decrease in the temperature of the heat entering the coals to close to normalized ones due to the fact that the heat flow goes through a rather long (labyrinth) path, on which heat is removed by the structures of the tank structure.

In the considered example, the smoldering of hookah coals occurs in the mode of open air access to the container due to a freely flowing oxidative reaction with atmospheric oxygen. Limiting the access of air to the smoldering zone of hookah coals allows you to increase the heat by limiting the release of heat flow into the atmosphere. To limit the heat from hookah coals escaping into the external environment, a cover 13 (Fig. 14) is used, which is put on the container.

The lid 13 is made in the form of a plate 15 connected with the handle 14, which is the upper part of the lid, and a side wall 16, which repeats the shape of the side wall of the container in plan. A side wall of the lid may be associated with the handle. In fact, a lid is a container turned upside down, the wall of which or the bottom is connected to the handle. The lid plate 15 can be provided with through holes 17 (slots) for passing air from the external environment into the container of the device or for releasing heat from the container into the environment. Through holes 17 solve the problem of releasing heat from the tank into the environment in a stationary mode of smoking a hookah and entering air into the tank in a dynamic smoking mode. As a rule, the lid is made of a material with low thermal conductivity (to prevent burns) or from the material of the container, but the handle of the lid is made of a material that ensures that it does not heat up more than 40 ° C during normal use of the hookah. The lid is made with holding and/or centering elements 19 to hold it from above on the side wall of the container.

In the stationary mode of smoking (a temporary pause between puffs), the heat flow from smoldering / burning hookah coals rises and mostly passes through the holes in the lid to the outside. The other part passes unnaturally and enters the cavity 7 between the plates 1-3 in the area where the smoking mixture is located. Thus, the mixture heating mode is maintained.

The present invention is industrially applicable. A feature of the invention is the multilayer construction of the tank bottom with a labyrinth heat flow outlet. The double bottom protects the hookah mixture from local overheating, as well as from the ingress of red-hot (burning) coal particles into the tobacco mixture. The container has a double bottom, hot air from the coals passes into the double bottom of the container, is distributed in the space of the double bottom and exits through the holes in the bottom bottom plate. This design ensures uniform heating of the hookah mixture by changing the temperature of the heat flow coming from the device into this mixture.
