A device for controlling a biofireplace burner shutter includes two panels mounted in the upper part of the burner, between which there are shutter elements including a shutter with a serrated edge, a handle protruding from a slot in the biofireplace casing, the handle having a toothed rack and rotatably fixed between the panels a gear located between the gear rack of the handle and the gear edge of the shutter.

Description

The utility model relates to controls for the shutter of the burner and is designed to adjust the height of the flame of the fuel cartridge of the biofireplace.

The following technical solutions are known from the prior art.

A known mechanism for controlling the shutter of a fireplace burner (application for US patent No. 20122210998, published 08/23/2012).

A control device for a chimney chimney flap is known, characterized in that a lever is attached to the flap axis with which a rod is connected, the free end of which protrudes from the wall of the fireplace, is equipped with an exhaust handle (RF patent No. 32577, published 01.05.2005).

The closest analogue to the patented solution is a control device for the shutter of the fireplace burner, the design of which contains a shutter that moves along the guides. The shutter has a handle that protrudes through the slot of the lid. When moving the handle along the slot, the shutter moves along the guides, thereby adjusting the width of the opening of the combustion zone (Canadian patent No. 2546173, 05/06/2005).

The disadvantage of the closest analogue is the location of the shutter handle near the combustion zone, leading to its strong heating, which creates a risk of burns when moving it by hand. To move it requires an additional long pusher, which creates inconvenience to the consumer. Also, the presence of slots for the shutter handle in the upper panel can lead to the release of biofuel vapors and their ignition outside the combustion zone.

The problem solved by the proposed utility model is to increase safety and at the same time ease of use of the shutter control device for the consumer during the operation of the bio-fireplace.

The problem is solved by developing an external handle that controls the movement of the shutter through the interaction of gear elements and does not heat up during the burning of the flame.

The technical result of the patented solution is to increase the safety of controlling the shutter of a biofireplace burner by eliminating the likelihood of burns to the consumer, which is ensured by moving the damper control handle to a safe zone from the point of view of heating.

The specified technical result is achieved due to the design of the device for controlling the flap of the biofireplace combustion zone, including two panels mounted in the upper part of the burner, between which there is a shutter with a serrated edge, a handle protruding from a slot in the biofireplace body, and the handle has a gear rack between the panels a gear is mounted rotatably located between the gear rack of the handle and the gear edge of the shutter. On the contour between the upper and lower panels are spacers that limit the movement of the shutter in extreme positions.

Due to the use of a three-layer design of the upper part of the biofireplace, a solid top panel without additional slots (there is only a burning gap), the use of toothed control elements for the shutter, it is possible to move the shutter control handle out of the combustion zone and out of the areas of strong heating of the biofireplace elements. Unlike the closest analogues, the handle is located on the side of the biofireplace body, which is convenient for the user and allows you to move the handle to the right / left to open / close the shutter with minimal effort. In addition, the composite design of the shutter reduces the contact of the handle with fire and prevents its heating, which could cause burns to the consumer’s hands. At the same time, there are no extra slots on the upper front panel of the biofireplace, which provides additional tightness of the combustion zone, allowing biofuel vapors to exit only through the combustion gap.

Next, the solution is illustrated by reference to the figures, which show the following.

FIG. 1 is a view of a shutter control device in an open position.

FIG. 2 is a view of a shutter control device in an intermediate position.

FIG. 3 is a view of the shutter control device in the closed position.

FIG. 4 is a general view of the assembled product from the side of the flap control handle.

The control device of the flap of the combustion zone of the biofireplace 1 is made in the form of a three-layer "sandwich", consisting of:

- bottom panel 2 mm thick;

- the middle part with a thickness of 3 mm, where all the elements of the damper (handle, gear, shutter) move;

- top panel 4 mm thick.

Holes are made in the panels, which, when the panels are installed opposite each other, form a combustion zone 2.

In the space between the panels there are elements of the shutter: shutter 3, which is larger than the opening of the combustion zone 2 and obscures the combustion zone 2 when moving the shutter. One side of the shutter is beveled and has a toothed edge 4.

The handle 5 of the shutter has a gear rack 6. The gear 7 is placed between the gear edge of the shutter 4 and the gear 6 of the handle in such a way that the teeth of the wheel are located between the teeth of the handle rail on one side and between the teeth of the edge of the shutter on the other side.

The handle 5 moves in the slot in the directions shown by the arrows in FIG. 1. At the same time, the gear rotates in the same direction as the handle moves, and the shutter moves in the opposite direction.

The shutter 3 has a slot 9, inside which there is a protrusion 8, attached to the bottom panel, and when the shutter 3 is moved, it slots 9 along the protrusion 8, specifying the direction of movement.

Opening the shutter 3 is carried out by moving the handle 5 to the right, which leads to the rotation of the gear 7 clockwise, which in turn leads to the movement of the shutter 3 to open.

On the contour between the upper and lower panels are spacers 10, which limit the movement of the shutter in extreme positions.

Closing the shutter of the combustion zone is carried out in the reverse order of movement of all elements of the damper.

In the manner described, by increasing or decreasing the combustion zone with the shutter, you can adjust the height of the flame of the biofireplace burner.
