TECHNICAL FIELD OF THE INVENTION

The present invention is directed to a boiler built into a piece of furniture, a piece of furniture for embedding a boiler, a method of installing a boiler and a method of maintaining a boiler. It applies, in particular, to boilers in homes and commercial or industrial premises.

STATE OF THE ART

Home boilers of people or companies with limited space currently have several drawbacks.

In the first place, these boilers are cumbersome because of the volume of the different parts composing them. This space is particularly troublesome in the case of boilers positioned in kitchens.

Second, the presence of these boilers in living spaces, such as a kitchen or a bathroom, harms the aesthetics of these places. Usually, these boilers are attached to a wall or wall and require connections to exposed pipes because of this positioning. This positioning also causes congestion of the walls or surfaces on which the boilers are positioned.

Third, the weight and the usual height positioning of these boilers causes maintenance and installation difficulties due to the inaccessibility of these boilers.

To overcome some or all of these disadvantages, existing systems position the boilers on wall brackets so as to de-clutter the floor of a room. However, these systems do not meet, in particular, the disadvantage related to the maintenance and installation of the boiler. Other existing systems compact the components of the boiler to reduce its bulk. However, these systems do not allow easy maintenance of the boiler because of the increased proximity between the various components.

DESCRIPTION OF EXAMPLES OF EMBODIMENT OF THE INVENTION The present description is given in a non-limiting manner.

In FIG. 1, which is not to scale, a sectional view of one embodiment of the boiler 10 which is the subject of the present invention is observed. This boiler 10 insertable in a cabinet, comprises: - an inlet 105 for a heat transfer fluid, - an inlet 110 for a fuel, - an inlet 115 for air, - at least one removable flexible hose 180 fixing, - a means 160 for detecting a branching anomaly; means 165 for transmitting a signal representative of the detection of a branching anomaly; means 170 for opening / closing at least one input; , 110 and 115, a means 175 for transmitting, to a remote control panel, a wireless signal representative of the detection of a connection anomaly, a means 120 for heating the coolant by combustion of the fuel, output 125 for the heat transfer fluid heated, - an output 125 for combustion gas, - a means 145 for fixing a conduit 150 rigid and removable connection - a means 130 for attachment to a support 135 moving in a piece of furniture, a handle 140 to move the boiler along an axis of displacement of the moving support, - a box 190 for reducing the noise volume of noise emitted by the boiler and - a means 195 for absorbing vibration of the boiler. The inlet 105 for a coolant is, for example, a conduit having means for attachment to a hose 180. This fixing means is, for example, a tapping or a screw thread positioned at one end of the inlet of in order to fix a connection to the fastening means. This connection is also attached to the hose 180 through a screwing action for example. The coolant is, for example, water. The inlet 110 for a fuel is, for example, a conduit having means for attaching to a flexible hose 180. This fixing means is, for example, a tapping or a screw thread positioned at one end of the inlet so as to to fix a connection to the fastening means. This connection is also attached to the hose 180 through a screwing action for example. The fuel is, for example, natural gas. The inlet 115 for air is, for example, a conduit having means for attachment to a flexible hose 180. This fixing means is, for example, a tapping or a screw thread positioned at one end of the inlet in order to fix a connection to the fixing means. This connection is also attached to the hose 180 through a screwing action for example.

In variants, the inlet for air 115 comprises a duct allowing the air to be drawn from the immediate environment around the boiler, this duct being connected to an electric pump, for example.

The device comprises, preferably, a flexible hose 180 per inlet, 105, 110 and 115, of the boiler 10.

At least one removable flexible hose 180 for fastening the inlets, 105, 110 and 115 to at least one irremovable fluid and fuel supply duct 185 is, for example, a rubber hose covered with a braided steel tube. . In variants, the pipe is made of plastic, made of stainless steel. Preferably, a flexible hose 180 configured to carry water is made of stainless steel and a flexible hose 180 configured to carry gas is made of plastic or rubber. This flexible pipe 180 is configured to have a length greater than the maximum distance between, on the one hand, the inlet, 105, 110 or 115, to which this flexible pipe 180 is associated, and, on the other hand, a pipe 170, when the boiler 10 is at one end of the displacement made possible on the moving support 135.

At least one irremovable supply conduit 185 is, for example, a ride pipe previously positioned in a room in which the boiler 10 is installed. Each supply duct 185 has an outlet positioned in the cabinet in which the boiler 10 is embedded thanks to an opening on a wall of this piece of furniture allowing the ducts 185 to pass through.

The means 120 for heating the heat transfer fluid by combustion of the fuel is, for example, a burner configured to carry out the combustion of natural gas entering the fuel inlet 110. The combustion of the fuel causes heating of the coolant entered in the inlet 105 for heat transfer fluid.

The heated coolant is discharged from the boiler 10 through an outlet 125 for heat transfer fluid. This heat transfer fluid outlet is, for example, a rigid and open cylindrical section pipe comprising a fastening means 145 to a rigid coupling conduit 150. This fixing means 145 is, for example, a so-called "American" or "bicone" fitting allowing a clipping of the conduit 150 to the coupling. This type of fastening means has the advantage of allowing quick and easy attachment or removal of the rigid conduit 150.

The fuel that has been burned is removed from the boiler 10 by an outlet 125 for combustion gas. This outlet 125 notably allows the evacuation of fumes and condensates resulting from the combustion of the fuel. This outlet for combustion gas is, for example, a rigid and open cylindrical section pipe comprising a fixing means 145 to a rigid coupling conduit 150. This fixing means 145 is, for example, a so-called "American" or "bicone" fitting allowing a clipping of the conduit 150 to the coupling. The cylindrical section pipe of the outlet 125 for combustion gas has a diameter greater than the diameter of the outlet 125 for heat transfer fluid so that the outlet 125 for the coolant and the outlet 125 for combustion gas are coarsely concentric.

The outlets 125 are preferably positioned on the same face of the boiler 10 as the handle 140 for embedding or extracting the boiler 10 of the furniture.

The fastening means 145 of a rigid duct 150 and removable connection between the concentric outlets 125 of the boiler 10 and a removable duct 155 for flue gas and heat transfer fluid allow separate evacuation of the combustion gas and heat transfer fluid by a single conduit. This evacuation by a single conduit reduces the volume dimensioning of the boiler 10. The rigid conduit 150 is further sealed.

The outlets 125 are preferably positioned on a lower part of the boiler 10 and facing downwards of the boiler 10, the rigid duct 150 then having a bend for directing the combustion gas and the coolant towards the exhaust duct 155. irremovable. This non-removable evacuation conduit 155 is, for example, a collective conduit for a sealed boiler, abbreviated "3CEp". This non-removable evacuation conduit 155 is for example positioned inside the cabinet in which the boiler 10 is recessed by means of an opening on the base of this piece of furniture. This non-removable evacuation conduit 155 is fixed to the rigid conduit 150 by means of a US or bicone type ratio, for example.

The boiler 10 further comprises a means 160 for detecting a connection anomaly between the rigid duct 150 and removable connection and the outputs 125 of the boiler or the evacuation duct 155 irremovable. This detection means 160 is, for example, a mechanical or electronic sensor configured to detect a contact between the rigid conduit 150 and the outputs 125 or the exhaust duct 155. This sensor is associated with an electronic circuit configured to control the sending a signal when a branching anomaly is detected. A branching anomaly may correspond, for example, to a leaky connection badly made by a user.

The detection means 160 is also configured to perform the detection of a connection anomaly between a flexible pipe 180 and, on the one hand, the inlets 105, 110 and 115 of the boiler 10 or, on the other hand, the supply ducts 185. This detection means 160 implements, to carry out this detection, other mechanical or electronic sensors similar to the sensors used to determine a connection anomaly of the rigid duct 150.

The means 165 for transmitting a signal representative of the detection of a branching anomaly is, for example, a light-emitting diode or a beeper, for example. When an anomaly is detected, the light-emitting diode changes color, for example, from green to red. In the case of a beeper, the beeper emits a punctual and periodic beep as long as a branching anomaly is detected. The anomaly detected may correspond to a connection anomaly of a flexible hose 180 or rigid conduit 150.

The opening / closing means 170 of at least one input, 105, 110 and 115, configured to keep each said input 105, 110 and 115 closed, as long as a connection abnormality of the connecting conduit 150 is detected is for example, a solenoid valve actuated by the electronic circuit of the detection means 160. When a connection anomaly is detected, a closing command of the solenoid valve is emitted by the detection means 160 until the anomaly connection is no longer detected. This solenoid valve prevents the boiler 10 from being supplied with heat transfer fluid, fuel and / or air. In variants, only the fuel inlet 110 is affected by the opening / closing means 170.

The opening / closing means 170 is also configured to keep at least one, or each, input 105, 110 and 115 closed, as long as a connection failure of the hose 180 is detected.

The transmission means 175, with a remote control unit, of a wireless signal representative of the detection of a connection anomaly of the connecting conduit 150 is, for example, an antenna configured to transmit a wireless signal to the Central. This wireless signal implements, for example, the Wifi standard or a data network of a cellular network such as the Internet. In variants, the transmission means 175 is wired and connected to a data network, such as the internet for example. In variants, the transmission means 175 transmits a wireless signal representative of the detection of a connection anomaly to a communicating portable terminal associated with the boiler 10.

The transmission means 175 is also configured to carry out the transmission of a wireless signal representative of the detection of a connection anomaly of the flexible pipe 180.

The box 190 for reducing the noise volume emitted by the boiler surrounds, for example, the boiler 10 and has acoustic insulation walls. These walls comprise, for example, a polystyrene layer positioned between two partitions.

The vibration absorption means 195 of the boiler 10 is, for example, a set of antivibration pads positioned under the boiler 10 or under the support 135 in displacement.

The fixing means 130 to a support 135 in displacement is, for example, a set of screws making it possible to fix the boiler 10 to a rail 139, this rail 139 acting as support 135 in displacement on a set of wheels 137 positioned along walls of the furniture so as to horizontally move the boiler according to an axis formed by the wheels 137.

In preferred embodiments, the displacement support 135 is conversely a set of wheels 137 configured to roll on rails 139 positioned inside the cabinet, these wheels allowing a displacement of the boiler 10.

More generally, the displacement of the boiler 10 implements at least one wheel 137 moving along a rail 139.

The boiler 10 comprises a handle 140 for moving the boiler 10 along an axis of displacement of the support 135 in displacement. This handle 140 moves the boiler 10 from an installation position to an exposure position of the components of the boiler 10.

Thus, as understood by reading the present description, the boiler 10 object of the present invention has several advantages. By moving the boiler 10 along an axis of the cabinet, in which the boiler 10 is recessed, maintenance of the boiler 10 is facilitated. This displacement generates association constraints between the inlets and the outlets of the boiler 10 with the supply and discharge ducts of the room in which the cabinet is positioned. The boiler 10 object of the present invention solves this problem through the rigid conduit 150 and the flexible pipes 180. The embedding of the boiler 10 in a cabinet allows to hide the boiler 10 and reduce the space generated by this boiler 10.

This piece of furniture 20 for embedding a boiler 10 comprises: at least one opening 205 for a supply duct for heat transfer fluid, in air and in irremovable fuel for supplying a heat-transfer fluid inlet and a fuel inlet for the boiler 10, at least one opening 210 for an irremovable exhaust duct for products of combustion and for condensates of the coolant for evacuating the products of combustion and the condensates of coolant generated by the boiler 10, a support 215 in displacement of the boiler so as to alternately position the boiler 10 facing the supply duct and the exhaust duct or at least partially outside the cabinet which comprises two parallel rails 220 and a means 225 for adjusting the gap between the rails 220.

The piece of furniture 20 roughly comprises six faces, five faces of which are fastened to one another in irremovable manner.

At least one opening 205 for a heat-transfer fluid, air and immovable fuel supply duct is, for example, an opening positioned on one lateral face among the irremovable faces.

At least one opening 210 for exhaust duct is, for example, an opening positioned on a lower face among the irremovable faces.

The support 215 moving the boiler is, for example, a set of rails 220 or wheels forming at least one axis of displacement for the boiler 10. The distance between the rails 220 is adjusted by an adjustment means 225 of the gap between the rails. This adjustment means 225 is, for example, a rack on which two rail supports 220 are positioned, these rail supports 220 each comprising a means of displacement along the rack and a means for locking the positioning of the rail support. . The moving means is, for example, a toothed wheel configured to move along the rack.
