Description
Technical field
The utility model relates to family and the equipment of place heating such as office in a kind of winter, specifically is warm (heat) blower fan of a kind of electricity.
Background technology
Existing winter, the equipment of place heating such as family and office was various in style, and the energy is different.Consider that from aspects such as the sanitation and hygiene energy are convenient the existing general electric heating equipment that adopts roughly has heating air conditioner, electrothermal furnace and electric warm-air machine etc.The heating effect of heating air conditioner is generally undesirable, and especially outdoor temperature is low more, and its heating effect is just poor more, and indoor heating surface (area) (HS is little, and indoor intensification effect is undesirable, and power consumption is too big, can loss-rate big, simultaneously, it heats agent has certain negative effect to atmospheric environment.Electrothermal furnace can only can not make indoor air temperature rise near making the body local heating by free convection heat transfer.Comparatively speaking, electric warm-air machine has certain use advantage, and indoor air temperature is raise, its can loss-rate again less than heating air conditioner, and atmospheric environment do not had any negative effect.
But the electric warm-air machine ubiquity of prior art is following not enough: the structure of electric warm-air machine (is the electric calorifier of CN2379725Y, the warmer of CN2349481Y etc. as notification number) is generally and is provided with an electric heater near air outlet, the cold air that enters electric warm-air machine only with the little electric heater of area of dissipation carry out a convection current contact heat promptly enter indoor, the heat of electric heater fails to obtain sufficient heat exchange, the wind of discharging is not warm, area to indoor heating is still less, indoor intensification effect is still undesirable, it is still bigger to consume energy, can loss-rate still bigger.Simultaneously, because the present technique field forms a kind of long-term common recognition, electric warm-air machine heating itself does not need to establish the insulation layer, so its metal shell very easily heats up to scald one's hand and peels, if the then easily aging distortion of plastic casing.Stay ventilation gap between inside and outside shell and stay mode such as louvre to solve if adopt, its effect is still undesirable, and simultaneously, it is indoor that part cold wind is entered without heating, both influenced indoor intensification effect, additionally increased energy consumption again.
The utility model content
The technical problems to be solved in the utility model is, overcomes above the deficiencies in the prior art, provide a kind of indoor heating surface (area) (HS big and energy consumption is little can little, the indoor intensification of loss-rate electric warm-air machine satisfactory for result.
Technical solution of the present utility model is, a kind of electric warm-air machine with following structure is provided, comprise the housing of sealing, main electric heater, with indoor cold wind air inlet that communicates and hot blast exhaust outlet and be located at electric fan in the cold wind air inlet, it also comprises main heat exchanger, attached electric heater, attached heat exchanger; It is that electric heater and heat exchanger are between the two for heat transfer by heat conduction or to leave the gap be that electric heater is the heat radiation heat transfer with heat exchanger between the two that main, attached electric heater is fixed together with master, attached heat exchanger respectively; Attached electric heater and attached heat exchanger be arranged in electric fan with the air channel of preheating chamber; The air inlet of main heat exchanger communicates with the preheating chamber at the air outlet place of attached heat exchanger, and the hot blast exhaust outlet of main heat exchanger communicates with indoor.
Described housing preferably is made of housing case and metal inner tube folder insulation layer; Described master, attached heat exchanger preferably all adopt the aluminium foil finned type heat exchanger.
After adopting above structure, the utility model had both kept the original advantage of the electric warm-air machine of prior art, had increased the following advantage that electric warm-air machine did not have of prior art again:
One, owing to increased main heat exchanger, the area of dissipation of main electric heater is multiplied, preheating chamber and attached electric heater in addition, the setting of attached heat exchanger, make the indoor cold air and the master that enter in the electric warm-air machine, attached electric heater and master, the heat of attached heat exchanger obtains sufficient heat exchange, make the heat of electric heater obtain fully effectively utilizing, its thermal efficiency is very high, it is awfully hot to enter indoor wind, indoor temperature rising speed and effect are all very good, the area of room air heating increases (same power consumption, its heating surface (area) (HS increases by 40%～50% than the electric warm-air machine of prior art).Heat its energy consumption of same careat descend significantly (same heating surface (area) (HS, its energy consumption descends 40%～50% than the electric warm-air machine of prior art) conversely speaking.Can loss-rate little.
Two, the setting of housing insulation layer, but all heats in the electric warm-air machine are all discharged by the hot blast exhaust outlet in the concentrated area, make the globality of indoor intensification harmonious better, also more accelerated indoor programming rate.Simultaneously, the setting of housing insulation layer has fundamentally solved the metal shell defective of decortication (lacquer etc.), the very easily aging distortion of plastic casing of scalding one's hand that very easily heats up.
Three, this electric warm-air machine is simple and compact for structure, and volume is little.
