The invention discloses a sofa heated by warm air, relates to the field of furniture, and particularly relates to heating of furniture such as sofas and chairs. A sofa heated by warm air uses a warm air blower to circularly heat air in the sofa. An air heating layer is added under 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, so that a directional heat transfer structure is formed. Two groups of flow guide pipes are respectively arranged at the air inlet and the air outlet of the fan heater, the flow guide pipes extend to each area of the air heating layer, and a plurality of small holes are formed in the flow guide pipes. The fan heater is installed inside or outside the sofa. The sofa has the advantages that the sofa can reach and maintain a proper temperature with small power, the energy-saving effect is remarkable, and the whole heating is uniform.

Description

Sofa heated by warm air

Technical Field

The invention relates to the field of furniture, in particular to the field of heating of furniture such as sofas, chairs and the like.

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 household bidirectional airflow intelligent sofa, which uses an electric heater to heat air entering from a fresh air pipe, and then heats the sofa through a fan and a wind disk. In such a forced air supply scheme, heat is easy to continuously and quickly escape along with the air flow, and energy is wasted. Application 201920932638.7 proposes an intelligent sofa with temperature adjusting function, which uses a heating pipe and a heating wire to heat air inside the sofa, and then blows hot air to a cushion through an exhaust blade. 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.

Disclosure of Invention

The invention aims to provide a sofa heated by warm air, which solves the problems of large energy waste and uneven heating in the prior art.

The technical scheme adopted by the invention for solving the technical problems is as follows:

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 enable air in the air heating layer to be uniformly heated, 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 hydrodynamics. 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 beneficial effects of the invention are:

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 heating layer below the elastic layer of cushion, back and handrail, the one side of air heating layer is towards the elastic layer, and the face that the elastic layer is relative 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 the heating effect, reduces the energy waste. In order to make the air of air zone of heating can the even heating, install two sets of honeycomb ducts respectively at electric fan's air intake and air outlet, the honeycomb duct extends to each region of air zone of heating, set up a plurality of apertures on the honeycomb duct, and optimize the distribution and the aperture size in hole according to hydrodynamics, beneficial effect is, this kind of water conservancy diversion structure can break through the hindrance of various barriers in the air zone of heating, optimize the air runner, make the intraformational air of air zone of heating can be even and smooth circulation heating, make the whole even heating of sofa ability. 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.

Detailed Description

The invention is further illustrated by the following examples in conjunction with the drawings.

Example one

In fig. 1, the embodiment of the present invention is a warm air heated sofa.

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 seat 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 seat 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.
