Definitions

  • the present invention relates to an electric boiler comprising at least one vertical cylindrical tank containing a heat transfer liquid, and at least one heating body immersed in this liquid, this tank comprising at least one inlet orifice for the heat transfer liquid and at least one orifice for outlet of this liquid, said inlet and outlet orifices being connected to a network of use.
  • boilers which generally include a storage tank for the heat-transfer liquid and a heat sink designed to heat this liquid. These boilers often contain a relatively large volume of water and therefore have a high thermal inertia. In addition, their size is such that they cannot be easily mounted in a small apartment and cannot be used as individual heaters. see, for example, GB-A-2,092,282.
  • the present invention proposes to overcome these drawbacks by providing a boiler of very small dimensions, which lends itself well to use as an individual heating device which can be mounted in a small apartment and in particular in furniture elements. a kitchen.
  • the inlet and outlet orifices are respectively coupled to a supply pipe and to a discharge pipe which are arranged tangentially with respect to the cylindrical tank, and in that said supply pipe is close to the bottom of the tank and said discharge pipe is close to the top of the tank, in such a way that a cylindrical turbulence oriented from bottom to top is formed inside said tank.
  • the boiler is characterized in that the tank has several inlets, each of which is connected to a supply pipe tangential to the walls inside the tank.
  • This tank can also have several outlets, each of which is connected to a tangential discharge pipe with respect to the interior walls of the tank.
  • the supply tube forms an acute angle with a straight line parallel to the axis of the reservoir.
  • the angle is advantageously between 0 and 80 °.
  • the boiler comprises several tanks mounted in battery.
  • these tanks can be mounted in series.
  • these tanks are mounted in parallel.
  • each tank contains a battery of elongated heating bodies arranged centrally in the volume of liquid contained in this tank.
  • the boiler can comprise four tanks arranged symmetrically along the sides of a square and the supply pipes on the one hand and the discharge pipes on the other hand are respectively connected at two points of the circuit of use .
  • the tangential tubes are distributed regularly around the walls of the tank.
  • the electric boiler 10 shown essentially comprises a vertical cylindrical tank 11 containing a heat transfer liquid and at least one heating body 12 immersed in this liquid.
  • the heating body consists of three immersion heaters 13 which are mounted at the base of a closure element 14 fixed to the upper end of the reservoir 11 to ensure a sealed closure of this reservoir.
  • the closure device 14 comprises a lower base 15 threaded, intended to be screwed into the neck of the reservoir 11, equipped with a complementary thread 16.
  • the latter is equipped with a supply pipe 17 close to the bottom of the tank and a discharge pipe 18 close to the top of this tank.
  • the inlet pipe 17 defines the inlet to the tank 11 and the outlet pipe 18 defines the outlet from this tank.
  • the inlet and the outlet are tangential and oriented in such a way that the circulation inside the tank takes place in the form of a cylindrical turbulence oriented from bottom to top.
  • the axis 19 of the supply pipe 17 forms with a vertical 20, an angle ⁇ which is preferably between 0 and 80 ° and advantageously close to 60 °.
  • the axis of the discharge pipe 18 can form a right angle with the vertical.
  • the electric boiler comprises a single cylindrical tank in which are housed the heating bodies necessary to ensure the supply of sufficient electric energy for. cause rapid and effective heating of the heat transfer liquid contained in this tank.
  • the embodiment according to Figure 2 and which is the preferred form of the electric boiler according to the invention, comprises four tanks 11 each containing a heat transfer liquid and intended to each receive at least one immersion heater to ensure the heating of the heat transfer liquid.
  • Each of these reservoirs comprises a supply pipe 17 and a discharge pipe 18 which are preferably arranged so as to allow a substantially tangential penetration of the heat transfer liquid into the tank and also a tangential discharge of this liquid from the tank.
  • the four reservoirs 11 are coupled together via one hand of their supply pipe 17 and secondly by their discharge pipe 18. All the supply pipes 17 are connected to a conduit inlet 21 and all the evacuation pipes are connected to an outlet duct 22.
  • ducts are connected to a usage network preferably comprising a certain number of heat exchangers constituted by heating radiators.
  • the supply pipes are arranged in such a way that the circulation inside the tanks takes place along a substantially helical trajectory going from the supply pipe to the discharge pipe.
  • the various reservoirs 11 are arranged in a star and connected to the outlet conduit 22 by the evacuation pipes 18.
  • Figures 4 and 5 illustrate a variant according to which the reservoir 11 comprises several supply pipes and at least one discharge pipe.
  • the inlet pipes 30 are arranged in such a way that they open out inside the tank at points angularly offset by 120 °.
  • these supply pipes are arranged substantially tangentially with respect to the inner wall of the tank 11 and finally their axis forms an angle ⁇ which is between 0 and 80 ° and preferably around 60 ° relative to the vertical.
  • This arrangement makes it possible to create inside the tank a helical circulation illustrated schematically by the arrows 31.
  • This helical circulation has the main advantage of improving the passage of the heat transfer liquid over the immersion heaters and thereby increasing the yield of the boiler by considerably reducing the time required to bring the heat transfer liquid to the desired temperature.
  • the discharge pipe 32 can be arranged in a horizontal plane. It is preferably mounted tangentially with respect to the walls of the tank. It can be split or even tripled. However, it will be noted that obtaining a helical turbulence inside the tank is essentially due to the geometric arrangement of the intake pipes which act as injectors.
  • the various immersion heaters are supplied with power through a circuit controlled either by a programmable device or by thermostats or by other temperature sensors. These different heaters can be ordered individually or in combination as required.
  • the heat transfer liquid is propelled by a pump mounted on the circuit (not shown) inside the tank (s) of the boiler.
  • the different supply pipes constitute a distributor which allows the same flow of fluid to be brought into the different tanks.
  • the helical circulation inside the tank ensures the best possible heat exchange between the immersion heaters and the heat transfer liquid.
  • the different tanks can be arranged in line instead of being arranged in a star. It is possible to connect them in series or to connect them in parallel.
