Multifunctional electric heater

Abstract

The invention relates to a multifunctional electric heater for purifying, humidifying and heating indoor air. A shell front plate, a shell left side plate, a shell right side plate, a shell upper cover, a shell rear upper plate, a shell rear middle plate and a shell base form a box body; the box body is respectively provided with a control panel, an air outlet mesh enclosure, a plurality of air guide vanes, an air outlet temperature sensing probe, two air inlet mesh enclosures and a power switch; the box body is internally and fixedly provided with a lower heat insulation box body, an upper heat insulation box body, a cross flow fan, a main circuit board, a temperature control probe and a temperature control switchgear, a high-voltage packet, an air inlet temperature sensing probe and a humidifying water tank; two heat exchange tube covers provided with far infrared heating tubes are provided with a plurality of heat radiating fins at intervals and fixed in the upper box body; a shell splint fixedly provided with a dust absorption mesh plate and a touch switch is fixed in the box body in the shell rear upper plate; and two rows of tapered mesh covers and two rows of discharging needles are fixed on the shell splint. The multifunctional electric heater has the characteristics of high thermal efficiency, energy source conservation and capability of decomposing formaldehyde contained in the air and achieving the aims of sterilizing and purifying the air.

Description

Technical field [0001] The invention relates to an indoor air purification, humidification and heating device, in particular to a multifunctional electric heater. Background technique [0002] Existing indoor heating devices, such as electric heaters, generally use radiant heating, but their shortcomings are that they rely on natural air flow for heating. The heating effect is not good, that is, the temperature difference between places close to electric heaters and places far away from electric heaters The heating effect is large, and the heating time is slow, the time is long, and the time is uneven.

Problems solved by technology

[0002] Existing indoor heating devices, such as electric heaters, generally use radiation heating. The disadvantage is that they are heated by natural air flow, and the heating effect is not good, that is, the temperature contrast between the place close to the electric heater and the place far away from the electric heater. The heating time is relatively large, and the heating time is slow, long, and uneven. The heating effect of the device that uses the direct heating method of the wind-blown electric heating wire solves the shortage of the radiation heating method, but the heating wire is always in a high current state. The power consumption is relatively large, and the shortcomings of the above two heating methods are also manifested in: the heated indoor air is dry, and if the indoor humidity is increased, a humidifier needs to be installed. The above two products have no function of purifying the air, and the cost is high and inconvenient to use.

The patent application number is 201210039423.5, which is an air purification and humidification multifunctional electric heater. Its characteristics are: 1. It uses far-infrared heating tubes to generate heat, shading heat exchange tube sleeves, heat sinks to absorb heat and dissipate heat, and heats up quickly. Far-infrared heating tubes 2. The electric fan blows the heated air on the water surface in the air purification and humidification tank at the lower end to take away water molecules, and the humidification effect is obvious 3. The electric fan heats up the indoor air reciprocally and blows it into the air purification and humidification tank, making the air contact with the water inside and keeping the floating dust objects in the air in the water, which plays a role in purifying the indoor air and is beneficial The human body is healthy, but there are still some deficiencies, such as the air purification effect is not optimal, the humidification effect is poor, and the germs, suspended solids in the air and formaldehyde gas produced by indoor living appliances cannot be removed.
