Description

The subject of this utility model is a device for collecting heat from a heating element, in particular a fireplace, and transferring it to a room.

BACKGROUND OF THE INVENTION

The need for heating devices of this type is enormous and steadily increasing, but the fireplace inserts still need improvements to increase their efficiency while reducing the amount of fuel needed to generate heat and the amount of unwanted gases released.

There have been experiments with forced air flow around the cast iron surface from which the fireplace inserts are made. This achieved a more efficient heat dissipation from the cast iron surface.

WO 9729327, part of the prior art, discloses a gas fireplace assembly comprising a turbine rotatably mounted in a first conduit through which flue gas flows. This turbine is coupled to free-flow fans located in a second duct immediately downstream of the gas burner and drives them so that the flowing air that is heated in the second duct is carried by the duct and pushed into the room.

Another solution in the prior art, Polish utility model application no. 116824, discloses a heating fireplace with a heat exchanger, which in a housing forming an air chamber comprises a fireplace insert with a focus and a flue, wherein the heat exchanger is located in the air chamber at the top of the box above the fireplace insert and the flue. The heat exchanger takes the form of radiator tubes. Between the cabinet and the fireplace insert is a partition separating heated air from cold.

The essence of the technical solution

The object of the present utility model was to develop a device that would increase the air flow around the heated fireplace material, in particular around its back wall, to capture heat and dissipate it into the room.

A device capturing heat from a heater and comprising a turbine and a vent is characterized in that an electrically driven turbine in the housing is mounted on its housing. In addition, the apparatus is equipped with a thermostat comprising a regulator and a temperature switch in the form of a head which are interconnected by a capillary, the housing and the rear wall of the heater forming a vent parallel to the rear wall, and there are openings on the turbine cover.

Preferably, the thermostat has a control range between 50 ° C and 300 ° C.

Preferably, these openings are protected by a grid.

Preferably, the device is used in heaters such as fireplaces.

Preferably, the turbine is equipped with anti-vibration pads.

The design of this device is universal and, after appropriate modifications of the vent, can be used in any heating element in the form of a fireplace. The solution according to this utility model greatly increases the comfort of using the fireplace, because the user has the option to decide at what temperature the rear wall the system will turn on and start to transfer heat more efficiently to the room.

In addition to increasing the thermal efficiency, the functionality of the device increases. Better efficiency means that less fuel (wood) is required to generate rated power, making the heater more economical. For the end user, this means fewer fuel injections into the heater and thus savings. This solution reduces emissions of harmful gases into the environment.

EXAMPLES

In a preferred embodiment, the heat sink comprises a turbine 3 in a housing 6 mounted on the housing 2, which together with the rear wall 1 of the fireplace forms a vent parallel to the rear wall 1 of the fireplace. housing

SK 7106 Υ1 and the box are made of structural steel S235JR. The individual elements of this construction are cut from sheet metal using a laser with an accuracy of ± 0.03 mm and then bent on the press brake. The use of such devices (numerically controlled machine tools, CNC) in the production process ensures that the individual elements of the system fit perfectly together. The casing 6 of the turbine 3 has two openings 7 and 8 for sucking in cold air from outside, which is directed into the vent. The holes are protected by a special grille to prevent the user from contacting the turbine blades. The end of the vent is shaped to direct the heated air over the fireplace towards its front. A single-phase thermostat is connected to the turbine electrical circuit. This thermostat comprises a regulator 5 and a temperature sensor 4 in the form of a head which are interconnected by a capillary. The head is mounted directly on the back wall of the fireplace, at a location previously determined by tests carried out with a pyrometer (non-contact thermometer). The thermostat control range is between 50 and 300 ° C. The user has very convenient access to the controller, which is intuitive to operate. Anti-vibration washers 9 were used to prevent vibration transmission to the vents during turbine assembly. The turbine is powered from a 230 V power grid and generates a noise level of approximately 35 dB that does not affect the convenience of the system at all. The efficiency of the turbine is approximately 135 m ³ / h at a maximum power input of 26 watts. If required, the system can be equipped with higher power turbines. Electrical connections are made of high temperature resistant silicon cables. The cables used are halogen-free (do not release harmful gases during combustion) and are self-extinguishing. The power cable is connected to the housing using a flexible grommet. Such a solution prevents the cable from breaking and tearing. The device is grounded, so it meets strict safety standards.
