RU226068U1 - AUTOMATIC HEAT SENSITIVE VENTILATION WINDOW - Google Patents

Abstract

A utility model may have a frame of various shapes with a damper installed in this frame, made with the ability to automatically rotate inside it when the temperature changes due to the fact that the window contains a bracket and a thermobimetallic rotation drive element with an attachment element on the bracket, pivotally connected to the bracket , wherein the thermobimetallic element of the rotation drive is made in the form of a thermobimetallic plate with a bend connected to the inner side of the frame by means of a fastening element, for example a thumbscrew.

Description

A utility model is claimed to be a technical solution for an automatically opening window designed to maintain a given temperature in rooms by automatically opening and closing when the set air temperature inside enclosed spaces (volumes) is exceeded or decreased. This design can be used in agriculture and as an automatic ventilation device for greenhouses and greenhouses on personal plots, as well as in other rooms where ventilation is required.

The task facing the window vent developers is to create a new vent design that is more convenient and economical to manufacture and reliable during operation.

The most similar in design and method of operation is known from the prior art: an Automatic heat-sensitive ventilation window (see Patent for utility model No. 144544), which contains a housing with a damper installed in it on an axis with the possibility of rotation and a thermobimetallic element for driving its rotation. The damper is equipped with a bracket fixedly attached to it, offset from the longitudinal axis of rotation of the damper and pivotally interacting with a rotation drive fixedly fixed to the body in the form of an L-shaped lever made of a thermobimetallic plate. The housing has a locking screw for stationary fixation of the damper through a stopper in the manual installation mode and a mechanism for adjusting the position.

The disadvantage of this window design is that the thermobimetallic drive element has a complex shape and is inconvenient to manufacture and install in the frame.

The inventive window is shown in figure 1 and figure 2.

In fig. 1 - window;

In fig. 2 - thermobimetallic element of the L-shaped rotation drive.

In fig. 3 - thermobimetallic element of the rotation drive with bends and an attachment element on the bracket with a welded ring.

In fig. 4 - thermobimetallic element of the rotation drive with bends and an element of the attachment to the bracket, made in the bend.

In fig. 5 - window with a stiffening element located on the surface of the front side of the damper.

In fig. 6 - window with a stiffening element located on the surface of the back side of the damper, where:

1 - frame;

2 - axis of rotation of the damper;

3 - stiffening element;

4 - damper;

5 - bracket;

6 - thermobimetallic element of the rotation drive;

7 - element of the attachment to the bracket;

8 - bend with nozzle;

9 - bend for fastening to the frame;

10 - fastening element.

The technical result of the proposed solution is the expansion of the range of vents with a thermobimetallic element of the rotation drive, where the vents can be of any shape (rectangular, round, trapezoidal, etc.) by changing the shape of the thermobimetallic element of the rotation drive 6. This change allows more simply mount the thermobimetallic element of the rotation drive 6 on the inner side of the frame 1, regardless of the shape of the frame, and the force creating the torque of the damper increases compared to the force applied to the damper in the analogue, because this force is directed perpendicular to the axis of rotation of the window, due to which the efficiency of the thermobimetallic element of the rotation drive 6 increases.

The range of vents can also be expanded due to options for the thermo-bimetallic element of the rotation drive:

the thermobimetallic element of the rotation drive can be made in the form of an L-shaped bent plate, one end of which has a welded connection with the attachment element on the bracket 7, put on the bracket 5 (see Fig. 2);

the thermobimetallic element of the rotation drive can be made in the form of a plate, the ends of which are bent in opposite directions (see Fig. 3, Fig. 4).

In this case, in all versions of the thermobimetallic element of the rotation drive, the bend 9 is rigidly attached from the inside to the side of the frame 1 by means of a fastening element, and the opposite end of the plate is hingedly connected to the bracket 5 by means of a connecting element 7, which can be used as a ring welded to the end thermobimetallic element of the rotation drive, or, in the case of making the thermobimetallic element of the rotation drive in the form of a plate bent on both sides - in the form of a round hole on the bend 8.

Depending on the material of the damper 4, the window may include a damper stiffening element 3, which can be located both on the front side of the damper 4 (see Fig. 5) and on the back side of the damper 4 (see Fig. 6). The rotation axes of the damper 2 can be rigidly fixed both to the frame 1 and to the stiffening element of the damper 3, which also increases the range of manufactured vents.

Description of the design of the proposed window

The automatic heat-sensitive ventilation window contains a frame 1, a damper 3 installed in the frame and rotatable on an axis 2, a thermobimetallic element of the rotation drive 6, a bracket 5, hingedly interacting with a thermobimetallic element of the rotation drive 6 fixed on the body. Thermobimetallic element of the rotation drive 6 made in the form of a thermobimetallic plate and has a bend that is rigidly fixed on the inner side of the frame by means of a fastening element 10, for example a thumbscrew bent at the ends in opposite directions.

The thermobimetallic element of the rotation drive 6 can be made in the form of a thermobimetallic plate having only one bend - bend 9, which is rigidly fixed on the inner side of the frame 1 by means of a fastening element 10, for example a thumbscrew, or in the form of a thermobimetallic plate having a bend at the ends 8 and bend 9, turned in opposite directions.

Bracket 5 has a hinge connection with the attachment element on bracket 7. Bracket 7 can either be welded to the thermobimetallic element of the rotation drive 6, or can be drilled in the bend 8 of the thermobimetallic element of the rotation drive 6.

If the damper is of sufficient strength, the bracket 5 can be directly connected to the damper, or the damper can additionally be equipped with a stiffening element 3, which can be made in the form of a metal plate and can be contact-connected both to the front surface of the damper 4 and to its rear side ( see Fig. 1 and Fig. 2), for example, with bolts. The rotation axis of the damper 2, inserted into the frame, can be attached to the stiffening element 3, or elements for fixing the rotation axis can be installed on it, having a rigid connection with the frame 1.

An axis 2 is installed in the frame 1, on which a damper 4 is rotatably installed.

The element for fastening the plate to the frame 10 can be made in the form of a screw and a wing nut, which allows this nut to be screwed in during manual assembly.

The size of the thermobimetallic element of the rotation drive 6 is designed such that when the plate is heated, the additional force created in this plate rotates the valve 4 to the desired angle.

The shutter 4 is preferably made of plastic or other sheet material.

The frame 1 is preferably made of metal, but can also be made of any shape-holding material: wood or plastic.

The shape of the frame can be different: rectangular, round in the form of a trapezoid.

The automatic temperature-sensitive ventilation window works as follows.

The edges of the damper 4 in the closed state (at low ambient temperatures) are adjacent to the inner sides of this frame, and when the temperature rises, the damper rotates across the frame 1 at an angle of up to 90°.

When the air temperature inside a closed room increases, the thermobimetallic element of the rotation drive 6 is deformed, resulting in a force transmitted from the thermobimetallic element of the rotation drive 6 through axis 5 to the damper 4. Due to the created moment of force relative to axis 2, the damper 4 begins to rotate and open synchronously with a gradual an increase in the indoor air temperature, and when the air temperature reaches 40...45°C, damper 4 takes a position with a rotation angle of 90° (opens completely). When the air temperature inside a closed room decreases, the thermobimetallic element of the rotation drive 6 is deformed in the opposite direction and the damper 3 begins to gradually close the flow area of the ventilation vent. When the indoor air temperature reaches 15°C, the damper rotation drive 4, made in the form of a thermobimetallic element of the rotation drive 6 from a thermobimetallic plate, ensures that the damper 4 completely covers the flow area of the ventilation vent.
