Description

GAS RADIATOR
TECHNICAL FIELD The present invention relates to a gas radiator.
More specifically, the present invention relates to a room-heating gas radiator.
BACKGROUND ART
A room-heating gas radiator normally comprises a burner, a combustion chamber, and a fan, which are housed inside a shell, through which a stream of air drawn from the room is conveyed and fed back into the room on withdrawing a given amount of heat from the combustion chamber. Room heating often causes a fall in the relative humidity of the air in the room, to the extent that humidification is required to restore a relative humidity level which is comfortable for human occupation.
Rooms are normally humidified using humidifying appliances comprising a tank and an electric resistor for evaporating water, or using a dish of water fitted to the heating appliance which heats and evaporates the water.
A dish is simpler and cheaper than an appliance, but often spoils the look of the heating appliance, and is not always easy to fit on.
DISCLOSURE OF INVENTION
It is an object of the present invention to provide a gas radiator, which provides for troublefree room humidification without spoiling the look of the gas radiator itself.
According to the present invention, there is provided a gas radiator, which comprises a shell having a number of lateral walls and housing a gas burner; a combustion chamber; and a fan for directing a stream of air through said shell; the gas radiator being characterized in that the shell comprises a seat located inside the shell, communicating with the outside of the shell, and for housing a dish of liquid.
The gas radiator according to the present invention is particularly advantageous by the seat inside the shell concealing the dish when fitted to the gas radiator.
BRIEF DESCRIPTION OF THE DRAWINGS A number of non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying drawings, in which:
Figure 1 shows a side view, with parts removed for clarity, of a gas radiator in accordance with the present invention;
Figure 2 shows a view in perspective, with parts in section and parts removed for clarity, of a detail of the Figure 1 gas radiator; Figure 3 shows a larger-scale section, with parts removed for clarity, of a detail of the Figure 1 radiator;
Figure 4 shows a larger-scale view in perspective of a dish fittable to the Figure 1 radiator;
Figure 5 shows a section, with parts removed for clarity, of a variation of the Figure 3 detail .
BEST MODE FOR CARRYING OUT THE INVENTION
Number 1 in Figure 1 indicates as a whole a room- heating gas radiator.
Radiator 1 comprises a frame 2 defined by a supporting plate, to which are fitted a combustion chamber 3, a burner 4, a heat exchanger 5, a fan 6 for directing a stream of air over the outside of combustion chamber 3 and heat exchanger 5, a fan 7 for feeding combustion air into combustion chamber 3 , and a control unit 8. A gas pipe 9 connects the gas mains (not shown) to burner 4.
Chamber 3 extends in a horizontal direction Dl along a substantially horizontal axis A, and is connected directly to burner 4, and via a header 10 to heat exchanger 5. Combustion chamber 3, exchanger 5, and header 10 have fins 11 extending perpendicularly to axis A to direct the air stream from fan 6 in a substantially vertical direction D2 and increase heat exchange between the combustion fumes and the air stream. Fins 11 are equally spaced with a spacing P in direction Dl .
Combustion chamber 3 comprises an inlet 12; an outlet 13; and a flow section S, which is perpendicular to axis A and substantially rectangular with the long sides parallel to direction D2. Inlet 12 and outlet 13 are surrounded by respective flanges 12a and 13a; and chamber 3 is defined by four flat walls 14 and 15, two of which (walls 14) are parallel, while the other two (walls 15) converge towards outlet 13 so that section S is minimum at outlet 13 and maximum at inlet 12. Flange 13a is connected to header 10; flange 12a is connected directly to burner 4; and walls 14 and 15 define a casing 16 extending about axis A.
Gas radiator 1 also comprises a shell 17 housing the above components and comprising two major lateral walls 18, only one of which is shown in Figure 1, two minor lateral walls 19 and 19a, a grilled top wall 20, and a perforated bottom wall 21. One major lateral wall 18 is fixed to a support, and the other major lateral wall 18 has a cover 22 for access to a control panel (not shown) of control unit 8. With reference to Figures 2 and 3, lateral wall 19a comprises a pocket 23 formed in shell 17 and for housing a dish 24 of water (Figure 4) . Both lateral walls 19 and 19a are curved with their concavities facing inwards of shell 17. The top half of lateral wall 19a with pocket 23 comprises an ogival, curved, outwardly-concave portion 25; and the bottom half of curved portion 25 is covered by a wall 26 integral with wall 19a and curved to form pocket 23 together with curved portion 25. Pocket 23 has a top edge 27 for supporting dish 24.
With reference to Figure 4, dish 24 has a mouth 28 surrounded by a rim 29, which projects outwards to rest on edge 27 of pocket 23; dish 24 tapers in section from mouth 28; and pocket 23 defines a seat 30 for housing, retaining, and concealing dish 24.
With reference to Figure 1, pocket 23 and, in use, dish 24 are located close to header 10 carrying the hot fumes, so that the water in dish 24 is heated and evaporated.
In actual use, the tapered shape of dish 24 enables it to be inserted into and removed from pocket 23 easily. For example, to insert dish 24, dish 24 is placed next to the top of curved portion 25, over pocket 23, and is then lowered into pocket 23 so that rim 29 rests on edge 27. To remove dish 24, the top, e.g. rim 29, of dish 24 is simply gripped, and the above steps repeated in reverse.
The location of pocket 23 is particularly advantageous by enabling dish 24 to be positioned over pocket 23 without projecting with respect to top wall 20, thus enabling dish 24 to be inserted and removed easily, even when gas radiator 1 is installed beneath a window sill.
Moreover, pocket 23 is formed integrally in wall 19a without substantially altering the design of gas radiator 1, and provides for concealing dish 24, which therefore need not be particularly attractive.
In the Figure 5 variation, 19b indicates a lateral wall forming part of a shell 17b and to which dish 24 can be fitted. Like shell 17, shell 17b comprises a wall 19 with no seat 31, two major lateral walls 18, top wall 20, and bottom wall 21. Wall 19b is made of aluminium alloy, as is the whole of shell 17b of which it forms part, and comprises, at the top, a seat 31 for housing dish 24 and accessible from the outside of shell 17b. Seat 31 is defined by an ogival opening 32 in wall 19b, and by a curved, inwardly-concave portion 33 located beneath a curved, outwardly-concave portion 34. Portions 33 and 34 are oppositely curved, are separated by opening 32 at their respective points of maximum curvature, and are offset at opening 32.
Portion 33 has a top edge 35 for supporting rim 29 of dish 24.
Dish 24 is inserted and removed in the same way as described with reference to seat 30 in Figure 3.
Seat 31 is formed easily by simply cutting an aluminium wall, and then deforming portions 33 and 34 in opposite directions to define opening 32 and seat 31. The Figure 5 variation has the further advantage of enabling the air stream to flow directly over dish 24 and so rapidly evaporate the water in dish 24.
