Sauna stove lid structure and a sauna stove equipped with the lid structure

Abstract

A lid solution of a sauna stove, in which the lid is formed of a lid plate (43) that covers the sauna stove and is made of glass and of a lid frame (44) that positions outside the sauna stove. The lid plate (43) of the sauna stove is broader than an outer mantle (20) of the sauna stove and the frame (44) moves the lid plate (43) through protrusions of the lid plate (43). When closed, the lid plate (43) is on its own weight on top of the stone drum or outer mantle (20) of the sauna stove. The frame (44) is a profile that is open from the front or side and the lid plate (43) of the sauna stove is replaceable without tools by pulling out an old lid plate and pushing in a new in replacement.

Description

BRIEF INTRODUCTION OF DRAWINGS

(1) FIGS. 1-3 show prior known lid structures of a sauna stove;

(2) FIG. 4 shows cross-section of a lid structure of a sauna stove according to a useful embodiment, when seen from the front; and

(3) FIG. 5 shows a side view of an opening mechanism of the lid.

DETAILED DESCRIPTION

(4) The invention will be described with reference to an applicable embodiment.

(5) FIG. 4 is a cross-section of a lid 50 (FIG. 5) of a sauna stove, seen from the front. On top of an outer mantle 20 of the sauna stove and the stone space 42 there is a lid plate 43 made of glass.

(6) As a moving mechanism of the glass plate there are U-shaped lifting profiles 441 or F-shaped lifting profiles 442, or frames 44, outside a sauna stove mantle. When the lid is closed, the glass plate rests on its own weight on the outer mantle 20 of the sauna stove. An opening of the lifting profile, that is as the frame, is substantially higher than the thickness of the glass plate such that the lid can settle onto the body of the sauna stove without engaging to the upper or lower peg 45 of the profile 441. The lid plate 43 can be made also of two or more parts. The parts of the lid plate may reach to be supported by opposite sides of the frame.

(7) In an embodiment, the top of the sauna stove is formed to comprise a plait or fold and the lid is formed such that the parts of the lid plate settle against the outer mantle of the sauna stove in a gentle upwards or downwards opening V-shape. In this case, the parts of the lid plate are preferably arranged to be removable from the right hand and/or left hand side of the sauna stove when seen from the front (such that the axle remains behind the sauna stove).

(8) The pegs 45 of the profile 441 need not be uniform but the profile 441 may be formed of plural, even point-like parts, that are substantially lined, forming a similar pattern as the pegs 45 of the profile 441. The lifting profile 441 may be also L-shaped, in which case it has no upper peg. This is possible because the glass is by gravity on the lower peg.

(9) FIG. 5 is a side view of an opening mechanism of the lid. In the rear edge of the sauna stove there is a lid axle or pivoting 22 of a frame. The frame 44 has an overhang 51, to which an axle 52 is fixed of an opening motor of the lid that acts as an opening organ 24. The axle opens and closes the lid. The lid plate 43 is on its own weight on a lower peg of the frame 44.

(10) The frame 44 may be rectangular when seen from top, but it can be also of another shape. Preferably, the frame is formed to enable sliding the lid plate 43 into the profile 441 of the frame 44 from one side, such as from front or side. The frame does not necessarily contain any restraint that should be removed or over which the lid plate should be lifted on removal from the profile 441 of the frame 44 even though some embodiments may provide one. A side of the frame may prevent a possible hot air flow between the lid plate 43 and the mantle 20 from directing straight towards an adjacent wall. In an embodiment, there is a detachably attachable side of the frame that covers also a fourth side and that is removable for replacing the glass.

(11) Following advantages are attained by the solution.

(12) The lid is inexpensive to manufacture.

(13) No thermal expansion caused tensions form between glass and metal. The lid plate can be formed of one or more parts. A lid plate originally made of one part can be replaced by two or more parts.

(14) Replacing the glass requires no tools. An old glass is pulled (for example from the front) away and a new one is pushed in replacement.

(15) Play between the frame profile and the lid plate reduces risk of breaking of the lid plate. If, for example, a bather tries to prevent closing of the lid by placing a sauna ladle on the outer mantle of the sauna stove while lid is closing, the linear actuator driving the lid may complete the closing movement thanks to the play without breaking the glass lid.

(16) The replaceable glasses can be dyed and patterned.

(17) The replaceable glasses are easy to remove for cleaning and/or painting of the glasses.

(18) The structure can be used in sauna stoves of all shapes, for example with round sauna stoves when seen from the top.

(19) The structure can be used independent of the method of heating, for example in wood heated and electrically heated sauna stoves.

(20) A lid plate of a sauna stove can be surrounded with the frame on 1-4 sides such that hot air flow directly sideways is prevented from the possible gap between the glass and the mantle and the glass plate floating on the sauna stove can be used with fire safety nearer inflammable wall structures than without a frame that covers a zone under and over the glass plate.
