Description
Technical Field
The utility model relates to the field of furniture, in particular to the heating field of furniture such as sofas and chairs.
Background
The furniture such as the sofa, the chair and the like is common furniture for people to live at home, and in cold winter, if the sofa and the chair can be heated, the comfort performance is greatly improved, and the health of people can be favorably influenced.
The heating mode of sofa and chair at present mainly is the electric heat membrane heating, and this kind of mode is the mode heating that utilizes heat-conduction, appears the heat source part overheated easily, feels uncomfortable problem, uses for a long time and still can lead to the user to appear adverse reactions such as dry skin, dry mouth and get angry. And the heat source is contacted with the human body in a short distance, so that the hidden danger of electric leakage exists.
To address the aforementioned deficiencies of heat conduction heating, improve comfort and save energy, a number of solutions to convection heating have emerged. Application 201811205154.9 proposes a home bi-directional airflow smart sofa that uses an electric heater to heat the air entering from the fresh air duct, and then heats the sofa with a fan and a wind pan. In such a forced air supply scheme, heat is easy to continuously and rapidly escape along with the air flow, and energy is wasted. Application 201920932638.7 proposes an intelligent sofa with temperature adjusting function, which uses heating pipes and heating wires to heat the air inside the sofa, and then blows hot air to the cushion through the exhaust blades. Although this type of scheme has avoided heating the new trend, because the cushion has thermal-insulated function, the heat gives off to other directions easily, and the energy waste is still great.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a sofa of warm braw heating to alleviate among the prior art the great and inhomogeneous problem of heating of energy waste.
The utility model provides a technical scheme that its technical problem adopted is:
a sofa heated by warm air uses a warm air blower to circularly heat air in the sofa. The warm air blower generally uses an electric warm air blower. The sofa cushion, the backrest, the armrests and other places which are often contacted with the human body are provided with thick sponge and other materials to form an elastic layer, so that the sofa cushion has a heat insulation function, if the air in the sofa is heated, the heat is dissipated towards other directions, and an ideal heating effect cannot be achieved. In order to make the heat generated by the electric fan radiate towards the direction of the cushion, the backrest and the armrests, an air heating layer is added below the elastic layers of the cushion, the backrest and the armrests. One side of the air heating layer faces the elastic layer, the opposite side of the elastic layer is composed of heat insulation materials, and the heat insulation capacity of the heat insulation materials is larger than that of the elastic layer. The core meaning of the air heating layer is to form a directional heat transfer structure, and adding other structures between the elastic layer and the air heating layer is still within the scope of the scheme. In order to uniformly heat the air in the air heating layer, two groups of flow guide pipes are respectively arranged at an air inlet and an air outlet of the electric heating fan, the flow guide pipes extend to each area of the air heating layer, a plurality of small holes are formed in the flow guide pipes, and the distribution and the pore size of the holes are optimized according to hydromechanics. The electric fan heater is installed inside the sofa, and for the convenience of installation and maintenance, the electric fan heater can also be installed outside the sofa, and extend the honeycomb duct out of the sofa.
The utility model has the advantages that:
the utility model provides a sofa of warm braw heating, uses the electric fan heater to the inside air cycle heating of sofa, and the electric fan heater generally uses the electric fan heater, and beneficial effect is that, the inside air of sofa is few, only needs very little power just can make the inside air of sofa reach and maintain suitable temperature, and then makes the sofa reach and maintain suitable temperature, and energy-conserving effect is showing. Increase an air zone of heating below the elastic layer of cushion, back and handrail, the one side in air zone of heating is towards the elastic layer, and the relative face in elastic layer comprises thermal insulation material, and thermal insulation material's thermal-insulated ability is greater than the elastic layer, and beneficial effect is, forms directional heat transfer structure, makes the heat shift towards the elastic layer, shifts towards cushion, back and handrail direction promptly, improves heating effect, reduces energy waste. In order to enable the air in the air heating layer to be uniformly heated, two groups of flow guide pipes are respectively arranged at the air inlet and the air outlet of the electric heating fan, the flow guide pipes extend to each area of the air heating layer, a plurality of small holes are formed in the flow guide pipes, and the distribution and the pore size of the holes are optimized according to hydromechanics. The electric air heater is installed inside the sofa, and is convenient for installation and maintenance, and the electric air heater can also be installed outside the sofa, and extends the aforementioned honeycomb duct outside the sofa.

Fig. 1 is a schematic view of the internal structure of the sofa heated by warm air according to the present invention.
In the figure, 1, a sofa, 2, an electric heating fan, 2-1, an air inlet, 2-2, an air outlet, 3, a flow guide pipe, 4, small holes, 5, a cushion, 6, a backrest, 7, an elastic layer, 8, an air heating layer and 9, heat insulation materials.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Example one
In fig. 1, the embodiment of the present invention is a sofa heated by warm air.
As shown in fig. 1:
a sofa 1 heated by warm air is characterized in that an electric heating fan 2 is arranged inside the sofa 1 to circularly heat air inside the sofa. The sofa 1 is characterized in that thick sponge and other materials are arranged at the positions, such as the cushion 5 and the backrest 6, of the sofa 1, which are often contacted with a human body to form an elastic layer 7, and an air heating layer 8 is additionally arranged below the elastic layer 7 of the cushion 5 and the backrest 6. One side of the air heating layer 8 faces the elastic layer 7, the opposite side of the elastic layer 7 is composed of a heat insulating material 9, and the heat insulating capability of the heat insulating material 9 is greater than that of the elastic layer 7. In order to uniformly heat the air in the air heating layer 8, two groups of flow guide pipes 3 are respectively arranged at an air inlet 2-1 and an air outlet 2-2 of the electric heating fan 2, the flow guide pipes 3 extend to each area of the air heating layer 8, and a plurality of small holes 4 are formed in the flow guide pipes 3.
