Description

 The present invention relates to apparatuses for heating, boiling and keeping water in a heated state for a long time. It belongs to the category of consumer goods and can be used in production, at home, in the field of catering / canteens, cafes, restaurants /, in collective rural and farm enterprises.

 A known apparatus for boiling water economar, comprising a housing with a built-in heating element, a device for turning it off, a lid with a handle, a fitting for draining water and an audible warning device; this unit is the closest analogue. The general disadvantages of the analogue are that the metal case during breakdown of insulation at any moment can be exposed to “touch voltage”, which is unsafe, especially in rooms with increased danger, with conductive floors / metal, concrete, earth, etc. /. In addition, after heating and boiling, they quickly cool down, and for re-heating the water, an additional energy consumption is required, and during the initial heating of the water through the metal casing, additional thermal energy is consumed. A serious drawback is that in the event of accidental rollover, the possibility of burns with hot water is not excluded. the cover and drain pipe do not have locking devices for locks, latches, etc.

 In addition, the possibility of direct ingress and concentration of moisture, which, flowing down the walls of the cavity or wires, can cause a short circuit at the contacts of the input connector, is not ruled out.

 The disadvantage is that the upper switch, due to unstable pressure and temperature during steam generation and at the same time consumption on the sound signaling device, will work unstably, which can cause burning or burning of contacts, and this reduces the reliability of the whole device. A rigidly mounted handle of the housing creates inconvenience when filling and full pouring of water through the lid. All these disadvantages are eliminated in the proposed apparatus. The technical result of this invention is the creation of the safest, most reliable and most economical heating apparatus, capable of not only heating, boiling, but also keeping water in a heated state for a long time.

 The essence of the invention lies in the fact that to achieve the technical result, the apparatus for boiling water economer, comprising a housing with a built-in electric heating element with a device for turning it off, a cover with a handle, a pipe for draining water and an audible warning device, is equipped with an additional thermally insulated body with a cover and heat-reflecting insulation while thermal insulation is placed between the housings and covers, a water drain fitting is located in the lower part of the housing, it is insulated and connected It is connected with a drain valve, the lid has locks and hinges, the steam chamber combined with a handle is installed, the sound signaling device is made as a bell, contains a vibrator and is placed in the chamber, and the cavity of the inner case and the steam chamber are connected by means of a thermally insulated pipe for supplying steam to the bell vibrator.

 In addition, the device for shutting off the heating element contains a float and an associated lever and a rod of insulating material.

 In (Fig. 1) shows the proposed apparatus.

 The device contains the following items.

 1. The outer electrical and thermal insulation wall of the housing.

 2. Internal heat-reflecting / mirror inside / wall. It can be simultaneously insulating.

 3. Water.

 4. Cover for external current and heat insulating housing.

 5. The cover of the internal heat-reflecting housing.

 6. Electrical and thermal insulation gasket.

 7. Lock or latch of electric and heat-insulating cover.

 9. Electro and heat-insulating rod.

 10. Electrical and thermal insulation switch lever.

 11. The body of the float.

 12. The float.

 13. The switch.

 14. Wires.

 15. Electrical insulating input.

 16. Electrical insulation block.

 17. Electrical plug contacts.

 18. Fuse.

 19. Closed type electric heating element.

 20. Drain shut-off valve.

 21. The locking device drain drain valve.

22. Electrical and heat insulating fitting
23. Respiratory opening.

 24. Heat and electrical insulating pipe.

 25. Vibrator mechanical bell.

 26. Stand vibromechanical steam call.

 27. Ringer cup holder.

 28. Cup vibromechanical bell.

 29. The hole connector.

 30. Funnel wave suppressor.

 31. The lower acceptable level.

 32. The steam chamber.

 33. Electro and thermally insulated handle.

 34. Steam passage holes.

 In general, the design of the “Electric double-insulated samovar consists of several main components: external heat and an electrically insulated body and cover 1 and 4; an internal heat-reflecting sealed body and cover 2 and 5. Between the walls of the cases and covers there is air or other heat and electrical insulation. Internal the case can be made of stainless steel with a polished inner surface or glass with a mirrored inner surface, but there can be other non-oxidizing heat-resistant materials and necessarily with a heat-reflecting surface. In this case, the energy saving will be slightly lower, but it will and will depend on the quality and thickness of the heat insulation between the cases. Covers 4 and 5 can be combined, that is, tightly interconnected by electrical and thermal insulation material and can be either removable with locking locks or latches 7 and 8, or folding with hinges and a lock or latch.The built-in heating element of the closed type 19 is electrically connected via wires 14 to the device for automatic disconnection if there is no, selection or boiling off of water, which contains: a float 12, a float chamber 11, an electric and heat-insulating rod 9 and a lever 10 and a switch 13. The sound signaling device from the start of boiling of bell-type water contains: a pipe 24, a vibrator 25, a stand 26, holder 27, ringer cup 28, steam chamber 32. An acoustic signaling device on the lid 4 together with an insulated handle 33.

 The shut-off valve 20, 21 is heat and electrically insulated by the fitting 22.

 Operating principle.

 Pouring water to the lower edge of the funnel-shaped wave-reflector 30, which is also an indicator of the upper water level and to reduce water boiling during boiling, and to reduce the ingress of water into the respiratory opening of the lid, closing and locking the lids 5 and 4 with locks or latches 7, connecting to the network through connector 17, heat the water to a boil. Having boiled, the vapors through the openings 34 under small pressure enter the breathing hole 23 and the pipe 24, at the outlet of which a vibrator 25 vibrates, which, by hitting the metal cup of the bell 28, signals the start or boiling of water.

 In the absence, selection or boiling of water to an acceptable lower level, the float 12 under the influence of its own weight and the weight of the rod 9 drops down and through a kinematic connection of the electric and thermally insulated rod 9 and the lever 10 automatically disconnects the electric heater 19 from the network, preventing its combustion.

 This economical, reliable and safe apparatus is capable of not only heating, boiling, but also keeping water in a heated state for a long time, and with high-quality manufacturing and good design can be competitive in the world market.
