Description

The utility model relates to means for satisfying a person’s vital needs, and more specifically to equipment for supplying hot food and, in particular, hot drinks, and can be used for storage, delivery, and dosed leave to a consumer of hot drinks, for example coffee.

The issue of providing consumers with food and drinks in dynamic times and / or in unforeseen situations, and in large quantities, has always been relevant and, as witnessed by history, has been solved in a variety of ways and means. With mass crowds, a more or less substantial part of the latter always has a need to satisfy natural needs, in particular a desire to satisfy thirst and at the same time be artificially stimulated, for example, with the help of a popular invigorating drink - coffee (or tea, or something else from the same a number of drinks). Means for satisfying such a need were created in different ways and had significant design differences according to the purpose and method of use. Particularly interesting in this regard are portable (i.e. portable) systems and, in particular, thermoses.

State of the art

Known containers, and in fact thermoses, electrically heated liquid contents. Such thermoses include, most often, coform tanks inserted one into another with a gap between the walls either evacuated or filled with a heat insulating material and a heat insulating lid (stopper), and the inner tank is equipped with a heater - thermoelectric, electric, and in some cases even a burner operating on gaseous or liquid fuel. [1-5].

These technical solutions have mainly narrow, special areas of use and limited functionality.

Thermoses and similar thermostatic devices with advanced functions are also known - in addition to storing and transporting liquids, providing the possibility of draining the contents. [6-8]

A common drawback of these technical solutions are also narrow, special areas of use and limited functionality.

A portable electrothermos is also known that contains two thermos thermally insulated in one general thermally insulated volume, while one thermos is heated to boil water, and the brewed substance (for example, ground coffee beans) is enclosed in a water-permeable shell and, after boiling, boiling water is poured into a thermos with brewed substance and thus get thermostated desired drink. [9]

The main disadvantage of this technical solution is the difficulty of use, in particular the preparation of the required drink, as well as a cumbersome constructive solution.

Closest to the claimed utility model in its technical essence and the achieved technical result, the proposed one is a portable thermal container containing a body with thermal insulation, an inner chamber and a lid and

This container is equipped with electric heating and temperature control. [10]

The main disadvantage of this technical solution is a narrow, specific area of use and limited functionality.

The technical result, the achievement of which the creation of the claimed utility model is aimed, is to expand the functionality by providing the possibility of quantitative control of the content and dosed flow rate of thermostatic fluid, as well as improving the logistic scheme of using the facility.

The technical result achieved is achieved by the fact that a portable thermos dispenser comprising an external case with thermal insulation and an internal chamber, a lid with a thermal sensor attached to it and an internal electric heater additionally includes a pressure sensor and a microcompressor mounted on the lid, connecting to the cavity of the internal chamber through a channel in the lid, as well as a drain hose with an electromagnetic valve functionally connected to the dispenser equipped with a meter, while the drain hose is connected to the outlet pipe from a calibration hole in the wall of the outer casing and communicating with the inner chamber through a connecting sleeve in the wall, an electric heater is placed between the casing with thermal insulation and the inner chamber under the bottom of the latter and connected to an external current source through an insulated adapter sleeve fixed to the wall of the outer casing, and the temperature sensor, sensor pressure, the solenoid valve through a dispenser with a counter, and a microcompressor are functionally connected to a control unit including a microprocessor and a GPS navigator and and a lid is mounted on the surface of the lid facing the cavity of the inner chamber for fastening the permeable bag, and the inlet of the drain hose in the wall of the inner chamber is closed by a replaceable filter.

Corresponding conformal containers with coaxial openings (or necks) installed one into the other with a gap, which, for example, can be filled with heat-insulating material, can be used as a thermos case. At the same time, the shape and physical dimensions of the composition of two containers, as well as the ratio of the sizes of its individual parts, are not significant and are determined only by ergonomic principles - for example, the portable version may have a cross-section in profile that fits comfortably to the back and has a capacity that complies with applicable standards manually transferred cargo.

Accordingly, both the form and the method of fastening and sealing the lid is not decisive and is limited only by the quality of the functional purpose.

The outer shell of the thermos can be equipped with straps with the possibility of adjusting the length. In this case, swivels can be installed on the case.

The thermos can also be equipped with a backpack bag with adjustable shoulder straps.

As an option, the drain hose can be optionally equipped with a flow heater.

Naturally, the drain hose is made of a polymer material having the appropriate flexibility, ductility, heat resistance and chemical inertness - i.e. comply with sanitary standards for use in the food industry.

The aforementioned provision applies equally to all parts, parts, assemblies and elements that make up the thermos-doser - corrosion resistance, chemical inertness, etc. performance.

Naturally, the inventive thermos-dispenser as a component of the system includes an electric power source (it should be noted that the current source is not presented on the diagrams and explanatory graphic materials, since it is the default object).

An external source of electricity (connected to a thermos-doser if necessary) can have a voltage of 220 V, safe 36 V or 12 V (in the latter case, the connecting wire can be made with a car cigarette lighter, which significantly extends the mobility and autonomy of the system as a whole.

As a temperature sensor, Danfoss, Sensata, Honeywell, etc. can be used. devices.

As a pressure sensor, sensors of the MPD-02, MPD-07 type can be used; CANOpen BUS CMP; DMP 331 et al.

As a microcompressor, (it should be noted that the liquid from the thermos is fed by gravity, however, the tightness of the container provided by a closed lid with a seal implies excessive pressure), for example, a Fuzzy Logic microcompressor (with automatic setting of the upper inflation limit).

An embodiment of the unit for maintaining and regulating the pressure of the medium (pressure sensor-microcompressor) in the inner chamber as a pair of pressure sensor with display - bellows manual pump [PSA-91P sensor (AUTONICS) - Hacoc TMG-040] is also possible.

Alternatively, miniature thermometers with a display, for example, Labon GA, or VT1189, can be used as an element of thermal monitoring. As an electromagnetic valve, for example, valves of the Omal EP system (415024, 412024) can be used

As a dispenser, for example, a dispenser of the type DRAGONLAB variable (adjustable volume) can be used.

As a counter, for example, meters like SI8 (RF) or type ST (Republic of Korea) can be used, while the latter has support for the RS 485 communication interface.

As a microprocessor can be used, for example, microprocessors C8008 9070R, C4004 H611, D4004 2676A, intel i-386 b, etc.,

As a GPS tracker can be used. For example, trackers TR-203A, TR-151.

It should be noted that in the claimed utility model standard units and blocks of various types and modifications of various manufacturers can be used, and the main criterion for using these units and blocks is their suitability for functional signs and parameters: power, design, dimensions and other similar technological and technical features and features.
