Description

Boiler installation device facilitating the replacement or repair thereof

The present invention relates to a device for installing the element producing heat or hot water (sanitary and / or for heating purposes of a room or premises), generally a so-called mural boiler, but may also concern a another type of heat generator such as a module connected to a heat pump PAC, for example an air-water heat pump, an appliance producing DHW (domestic hot water), ... The installation of the boilers according to the state of the technique requires fixing the device to the support (usually a wall of the building), as well as adaptations of the pipes, the elements of smoke and electrical connection. The replacement of a boiler involves an expertise of the person carrying out the work but also of the working time and the material with all the costs that implies. Such a replacement also requires emptying the heating system, since in general there are no valves on the circuit.

The boilers are becoming more and more efficient, so that their size varies during the improvements and according to the brands. This implies to the installer important adaptation work.

Another problem inherent to the installation of wall boilers is that it is often necessary to use new anchors in the wall, which can cause problems of embrittlement of a part of the wall, for example if a new anchor point is too close to an old anchor point.

The present invention essentially relates to a system allowing simple and rapid disassembly or replacement of the boiler (or an alternative device) by an installer even poorly qualified, while avoiding problems of connection or leakage, and even problems anchor points. In just a few minutes, one boiler can be replaced by another and the installation can be returned to service. This greatly facilitates the maintenance work, repair or adaptation of the device to technological developments or user needs. It also makes it easier to switch from an installation with a boiler producing instant hot water to an installation with DHW (domestic hot water) accumulation, or even to an air-water heat pump. Throughout the lifetime of the installation, the user can easily and inexpensively adapt the heat generator to the changing needs and benefit more easily from technological developments. The manufacturer ensures greater loyalty to its brand. For the installer, the work of the first installation and the management of future interventions are simplified.

Features and details of an advantageous embodiment (given by way of example only) will become apparent from the following detailed description in which reference is made to the accompanying drawings.

In these drawings:

Figures 1a and b are perspective views of the support Figures 2a and b are perspective views of the boiler

Figure 3 is an overview of the support with the boiler

Figures 4a and b show the quick-connect systems for fumigation

Figure 5 shows a schematic diagram of the contents of the lower housing of the support.

The present invention consists of a support (S) with a frame (14) which will be fixed to the wall by any means of attachment (eg screws, hooks, etc.). The top of the support is equipped with an element (14B) with tubes 2A, 2B adapted to be connected to the smoke ducts (1) (supply of fresh air, extraction of fumes).

The bottom of this element has two pipes (2), one for the arrival of air fiais to the boiler and another for the discharge of flue gas. These two pipes are connected to the boiler by means of quick-fit couplings (38) or elements closing around the ducts (32).

The bottom (or face resting on the wall) of the support (14) is equipped with a device for hanging the boiler C by simply laying on a slide (3). Such a slide 3 makes it possible to move the boiler C by simple translation so as to better adapt the position of one or ducts, for example flue gas exhaust from the boiler. It can also be equipped with hooks up and down (4) for the installation of safety straps during installation and removal of the boiler. Said hooks can also be used to limit the displacement of the boiler during the removal of means solidarisant the boiler C on the support S.

The bottom of the support or lower element 14A is equipped with a housing (5). The upper part of this housing has different connections 6 necessary for the connection of the boiler to the installation (19) (29) (gas inlet, water, inlet / return of the heating circuit, DHW outlet, condensate evacuation), as well as a guide support (7) for accurately positioning the boiler above the connections (6) in order to have only to insert a seal and screw each connection. These connections can also be of the type quick couplings secured by a clip or any other means. The housing 5 is advantageously removably mounted on the frame 14.

The housing (5) has the valves necessary to isolate the boiler (10) of the various circuits or installations of the house or buildings, but also one or more valves for filling the installation (8) and purging the boiler ( 9). For ease of use and to avoid handling errors, the valve groups (boiler isolation, purging, filling) can be recognized by color codes.

The housing 5 is also advantageously equipped with an outlet to an expansion vessel (11) and a housing (12) for electrical connection and control accessories.

The wall bracket is connected to the heating system via the housing (5).

The present invention includes a wall mount for a heat generator. The wall bracket is manufactured in a lens of great durability and reliability. It consists of a rigid back (14) having orifices for passing the screws that will fix it to the wall. It also comprises a transverse hook bar (3) about two-thirds of its height and two guide elements (7) in the vicinity of the lower housing to position and maintain the boiler at a height and distance well defined.

The top of the frame 14 has a horizontal return (forming the upper element 14B) to the front on which are fixed two pipes (2A, 2B) with characteristics adapted to allow an air supply and a discharge of the burnt gases, a the pipes connected, on the one hand, to ducts opening out of the building, and on the other hand to boiler ducts. The lower end of these pipes 2A, 2B is positioned in height, to ensure spacing (advantageously standardized by the manufacturer of the boiler) with the upper end of the air supply ducts and flue gas discharge of the boiler. The lower end of the pipes 2A, 2B is adapted to cooperate with quick connectors (32 or 38). The upper part of these pipes 2A, 2B is connected to an adapter (advantageously single) (1) intended to be connected to a chimney of the building. This adapter can be dismantled to allow the installer to select the desired chimney outlet type (80-80, 60-100; 80-125, with non-return valve, straight or angled ...). The adapter 1 will advantageously be adapted to provide a connection to a conduit with characteristics in accordance with the wishes of the installer. The upper element 14B then advantageously comprises a branch box 14D for connecting the inner channel of the adapter 1 to the pipe 2B and connecting the outer channel of the adapter 1 to the pipe 2A.

The housing 5 can be designed to be detached from the frame 14. This removable housing 5 allows easy attachment of the frame 14 on a wall. The upper part of this housing has the connections (6) to the boiler for the outlets of the gas supply pipes (28), to go (27) and return (26) of the heating circuit, inlet of cold water (24) (or Arrival / Return to an external exchanger) and hot water outlet (25) (or Arrival / Return to an external exchanger). These connections 6 can be of the type secure quick connectors (for example by a clip). The frame 14 may optionally be equipped with a system that moves the boiler vertically relative to the housing 5 or a system for moving vertically at least the upper part of the housing 5 relative to the boiler. This then allows an easy correct placement of the boiler with respect to the position of the connectors 6, and thus allows, after bringing the boiler closer to one another to the connections 6, to connect the connections 6 to the boiler tubes by means of simple free nuts (with screw thread), with a seal provided by a suitable seal. Sealing is then done by placing a suitable round seal and tightening by nut (hexagonal) on the screw thread of the boiler tube. The upper part of the casing 5 is completed by an orifices (15) allowing the introduction of a discharge pipe (advantageously of the flexible type) of the condensates. The different dimensions (diameter, height, spacing) meet for example the standards of a particular manufacturer of the boiler. Thus, when the boiler is placed on the support following the guides (7) and the hooking bar (3), the smoke outlets (18) will be ideally positioned to be connected using quick couplers (32 or 38). ) and the various connections (19) gas, hydraulic and condensate drain (29) located at the bottom of the boiler will be precisely located above the connectors 6 positioned at the top of the housing (5) so that it does not remain operator to insert a gasket and screw tighten a free nut for each fitting.

The bottom of the housing 5 presents the outlets with screw threads (13) allowing the connections of liquid, gas and condensate discharge (33). The inside of a housing corresponds, for example, to the schematic diagram shown in FIG. 5 with the presence of a siphon for the evacuation of the condensates (23), the non-return valves 21 and possibly a filter (20). It will advantageously be equipped with at least one gas shutoff valve (10) and one valve (10) for each element of the hydraulic circuit, thus making it possible to isolate the support and the boiler from the installation and if necessary to Ventilation opening to meet current safety standards for gas. It will also include on the inlet (s) and return (s) of the heating circuit a deflection with valves (9) to purge water from the boiler before disassembly and after isolating it from the installation and ideally valve arrangement (8) for controlling a filling set (22). The cold water inlet and the DHW outlet (domestic hot water) each have a bridge (16) coupled to a polarizer preventing the placement of boilers with DHW production by external balloon when the bridge (16) is present. When placing a boiler with a flask or other type of external heat exchanger, this bridging must be dismantled, providing the necessary connections to the heat exchanger (A / R to the heat exchanger coil, cold water inlet and DHW outlet). .

On one side of the housing, a connector (12) will be placed which will be connected to the electrical network and to the regulation elements (generally by two-wire BUS). This connector will connect the boilers with a cable equipped with a simple plug.

The design of the boiler when it remains very similar to that of a conventional boiler. The special requirements are a standardization of the positioning of the smoke outlets (18) and the connections to the heating circuit (19), DHW, gas, condensate drain (29) and electrical connector (17). As well as a standardization of the outer shape (30) so that the boiler is positioned perfectly and stably on the attachment bar and the guides of the support. The boiler may be provided with small protective blocks for laying the appliance on the floor (31). On the other hand, the manufacturer will be able to reduce the manufacturing cost of the boiler by integrating elements such as filters, non-return valves, a filling set, etc. into the wall support. The boiler will no longer have to be equipped with a boiler. expansion tank if the support requires the placement of it at the installation. The general design also becomes simpler because the boiler must not be planned to be repaired on site and therefore mainly by the front of it, but allow a repair in the workshop or on site with a 360 ° access or repair by ensuring a possible horizontal displacement of the boiler relative to the frame.

With regard to quick-fitting couplings, it is possible, for example, to use a coupling which is positioned around the end pieces and with a hinge (35) closed by a clamping clip (36) or a coupling which is tightened by screwing on a no screws (37), these fittings being provided with the necessary seals (34)
