Abstract
A boiler particularly for humidifiers, provided with a tank, supported by supporting elements, which have a filling and discharging orifice. A centrifugal discharge pump is supported by the supporting elements in a position that faces the orifice, so that the axis of its impeller substantially coincides with the axis of the orifice.
Description
- The present invention relates to a boiler particularly for humidifiers.
- Boilers are currently known which comprise:
- a substantially cylindrical tank, provided with a filling and discharging orifice;
- a support, which can be associated with a wall and is adapted to support the tank in a substantially vertical position;
- a centrifugal pump, which is arranged at the orifice and is adapted to empty the tank.
- Usually, commonly commercially available generic centrifugal pumps are used.
- Pumps of this type are associated with the support at the orifice of the tank and the axis of their impeller is substantially perpendicular to the axis of the orifice.
- A duct for connection between the orifice and the pump casing faces the impeller axially, while a delivery duct is arranged radially to the impeller to discharge the liquid aspirated by the pump through the connection duct.
- This solution has drawbacks, including the fact that it is necessary to provide suitable connections between the tank, at the orifice, and the pump connecting duct, which is sized by the pump manufacturer for generic uses and therefore is not dedicated to connection to the tank of the boiler.
- Another drawback of such boilers is that since the discharge pump is arranged with an axis that is substantially transverse with respect to the axis of the tank, it is particularly bulky.
- The aim of the present invention is to provide a boiler, particularly for humidifiers, that has, other characteristics being equal, a smaller space occupation than currently known ones.
- Within this aim, an object of the invention is to provide a boiler that has a pump dedicated to the connection to the tank and therefore does not require adapters for their connection.
- Another object of the invention is to provide a boiler that is structurally simple and easy to use and can be manufactured with low costs.
- This aim and these and other objects that will become better apparent hereinafter are achieved by a boiler, particularly for humidifiers, provided with a tank, supported by supporting means, which has a filling and discharging orifice, characterized in that it comprises a centrifugal discharge pump that is supported by said supporting means in a position that faces said orifice, the axis of the impeller of said centrifugal pump substantially coinciding with the axis of said orifice.
- Further characteristics and advantages of the invention will become better apparent from the following detailed description of a preferred but not exclusive embodiment of the boiler according to the invention, illustrated by way of non-limiting example in the accompanying drawings, wherein:
-
FIG. 1 is a perspective view of a boiler according to the invention; -
FIG. 2 is a perspective view of a detail of the boiler according to the invention, without the tank; -
FIG. 3 is a top plan view of the detail shown inFIG. 2 of the boiler according to the invention; -
FIG. 4 is a sectional view of the boiler according to the invention, taken along the line IV-IV ofFIG. 3 ; -
FIG. 5 is an enlarged-scale sectional view, taken along the line V-V ofFIG. 3 , of the boiler according to the invention; -
FIG. 6 is a front elevation view of a boiler of the currently known type. - It is noted that anything found to be already known during the patenting process is understood not to be claimed and to be the subject of a disclaimer.
- With reference to
FIG. 6 , the reference letter A generally designates a known type of boiler, provided with a cylindrical tank B that has a filling and discharging orifice connected by means of a connector C to a centrifugal pump D. - In particular, the tank B is arranged vertically and has the tubular connector C arranged substantially vertically.
- The centrifugal pump D is radially associated with the connector C, and therefore its axis E, at right angles to the axis F of the connector C, is substantially horizontal.
- A filling duct G is associated with a filling port provided radially to the connector C in order to fill the tank B.
- With reference to
FIGS. 1 to 5 , thereference numeral 10 generally designates a boiler, particularly for humidifiers, which is provided with atank 11 that is conveniently cylindrical, is supported by supportingmeans 12 and is provided with a filling and dischargingorifice 13. - A particularity of the
boiler 10, according to the invention, is that it comprises acentrifugal discharge pump 14 supported by the supportingmeans 12 in a position that faces theorifice 13. - The axis X of an
impeller 17 of thecentrifugal pump 14 substantially coincides with the axis of theorifice 13. - Advantageously, the
centrifugal pump 14 comprises a casing 15, which has achamber 16 for accommodating theimpeller 17 that is associated with aneck 18 for connection to theorifice 13. - At least one
port 19 for filling thetank 11 is conveniently provided on theneck 18 and at least one dischargingport 20 is conveniently provided on theaccommodation chamber 16. - Advantageously, the
boiler 10 according to the invention comprises filling and dischargingducts 21 for thetank 11. - The supporting means 12 conveniently comprise a
panel 22 that can be associated with a wall and is provided with ashelf 23 for supporting thecentrifugal pump 14 and with supportingbrackets 24 for thetank 11. - The filling and discharging
ducts 21 preferably comprise - a filling
duct 25, which is preferably associated with the fillingport 19, - a discharging
duct 26, which is conveniently associated with the dischargingport 20. - Conveniently, the
boiler 10 according to the invention comprises - a filling
connector 27, supported by theshelf 23 and connected to the fillingduct 25, and - a discharging
connector 28, which is supported by theshelf 23 and is connected to the dischargingduct 26. - In practice it has been found that the invention achieves the proposed aim and objects, providing a boiler, particularly for humidifiers, which has, other characteristics being equal, a smaller space occupation than currently known ones, by way of the fact that it comprises a dedicated centrifugal pump arranged coaxially to the orifice of the tank.
