Definitions

  • the present invention relates to a heating device comprising an insulating casing divided into two upper and lower compartments enclosing a thermal storage block provided with electrical heating resistors, respectively a heat exchanger and a fan.
  • the storage heaters generally include a block of refractory bricks, electrical resistances to heat this block, a closed loop circuit to circulate air in order to extract the heat accumulated in the block, a fan placed in this circuit and an air / water exchanger to heat the water of a central heating installation.
  • all the other elements are susceptible to failure, hence the importance of designing a device allowing rapid troubleshooting. Indeed, such a device called to operate without interruption for several consecutive months, it is essential that the failure of one of the organs can be repaired quickly. Depending on the position of the organs, they are difficult to access and intervention can be made even more difficult due to the heat accumulated in the block. These various factors can therefore make the repair long and painful.
  • the faulty part on the organ responsible for the failure may require a more or less delicate intervention, this part may possibly be lacking and, once the organ has been repaired, it must be replaced. be correctly positioned in the appliance.
  • DE-OS 1,579,181 relates to an accumulator heater in which the fan is integral with a casing which is detachably mounted on the lower part of the apparatus and which advances on the front face thereof.
  • a heat exchanger and a deflector are slidably mounted on two rails, extending under the accumulation block.
  • the fan was brought back in a way towards the front to make it independent and move its motor away from the hot air channel and a deflector was placed in the normal place of the fan to guide the air through the fan wheel.
  • the object of the present invention is to remedy these drawbacks at least in part by proposing an apparatus the design of which greatly facilitates any urgent intervention following the failure of an organ while offering protection to sensitive organs vis-à-vis heat.
  • the subject of this invention is a heating appliance comprising an insulating casing divided into two upper and lower compartments containing a thermal storage block provided with electrical heating resistors, respectively a heat exchanger and a fan, this appliance also comprising a closed circuit air circulation channel having convex channels passing through said block, connecting a distribution channel to an air collecting channel, both communicating with the outlet, respectively the inlet of said fan through said heat exchanger .
  • This device is characterized by the fact that this heat exchanger and this fan are integral with a support since mun removably mounted in the lower compartment, at least a portion of this support serving to delimit the lower part of said air circulation channel and forming a partition between the drive and pivoting members on the one hand, and the fan wheel on the other hand located inside this channel.
  • the apparatus illustrated comprises a frame 1 in the form of an inverted U. Its horizontal part carries a stack of refractory bricks 2 forming the accumulation block 3. Cast iron elements 4 are interposed between each brick level 2. These elements 4 each provide a housing 5 receiving an electrical resistance 6. Convection channels are formed on the faces of the elements 4 between the opposite faces of the accumulation block 3 adjacent to the front face illustrated by this figure. These channels make an air distribution channel 7 communicate with a collecting channel 8. Two openings 9 and 10 communicate the channels 7 and 8 respectively with the lower space located between the branches of the U-shaped frame 1. A covered metal casing internally with thermal insulation, the envelope covers the entire part of the device which has just been described and thus forms an upper compartment of this device intended to be closed by an insulating panel placed against the face of the accumulation block 3 illustrated.
  • a lower compartment is formed inside the frame 1 in the shape of an inverted U, and is intended to receive a drawer 12 illustrated in the pulled position and between two front plates 12a and 12b of which are arranged an air-water heat exchanger 13 intended to come at a certain distance from the vertical branch of the frame 1 to allow the passage of the air leaving the opening 10, a tangential fan of which we essentially see the motor 14 disposed on the front of the front plate 12a of the drawer 12 the wheel of which extends over the entire depth of the drawer 12 and an air distribution flap 15 mounted oscillating and controlled by a synchronous servo-motor 16 also disposed on the front of the front plate 12a of the drawer 12.
  • This distribution flap 15 is used to distribute the air between the opening 9 and a bypass passage formed under the horizontal branch of the frame 1. This air distribution is carried out as a function of the power necessary for heating the water.
  • the flap 15 is constituted by a half-cylinder oscillating between the two limit positions in which it closes the opening 9, respectively the bypass passage.
  • a seal 12c placed behind the front plate 12a bears against the frame 1.
  • a seal can also be placed behind the rear plate 12b, in particular to protect the rear bearing from the fan zone .
  • the air-water heat exchanger 13 is connected to the central heating circuit by two conduits 17 and 18 for supplying and discharging water respectively.
  • the contact between the transverse branch of the frame 1 and the metal casing 11 ensures a slight heat loss, at most 5% when the accumulation block 3 is at its maximum temperature of 650 ° C.
  • the role of this loss is to provide protection in the lower compartment and prevent the building from buckling and the water from turning into steam in the event of a power failure occurring when the accumulation block is very hot. Tests have shown that a small loss is enough to achieve this goal. The energy expenditure is also tolerable, the loss of 5% decreasing as the temperature of the accumulation block decreases.
  • the drawer 12 housed in the lower compartment of the appliance contains all of the members liable to cause a breakdown necessitating the shutdown of the appliance and consequently the shutdown of the heating installation.
  • the drawer 12 can be separated from the appliance by removing the panel from the casing attached to the open face of the appliance illustrated in the drawing, by disconnecting the conduits 17 and 18 from the water circulation circuit and by pulling out the drawer.
  • the breakdown requires significant work or if this breakdown occurs at a time when it cannot be repaired quickly, it suffices to replace a spare drawer instead while waiting for the cause of the breakdown to be repaired.
  • Such an intervention requires only a few minutes of work so that it can be done in an emergency even on a public holiday, without causing an extended shutdown of the installation. For this, the installer only needs to have a spare drawer in working order.
  • This feature is important since it allows the installation of the device, only its side face, giving access to the drawer 12 and the electrical resistors 6, to be released.
  • the resistors 6 can be removed from the block 3 by simply sliding them out of their housings 5.
