Abstract
The utility model relates to a mixed fused salt heat accumulating type electric heater which comprises an outer machine case. A front shell, a rear shell, a top cover, and a base plate are assembled to form the outer machine case. An operation panel and an air outlet are arranged on and formed in the upper portion of the front shell. A wall bracket is arranged on the rear shell. A draught fan is arranged at the bottom of the outer machine case and fixed on a draught fan fixing plate. A fused salt box which is full of fused salt is arranged in the center of an outer shell. Heating pipes are arranged in the fused salt box and fixed on the top cover of the fused salt box. A temperature controller, a heater power source wire, and a draught fan power source wire are further installed on the top cover of the fused salt box. Two air ducts are arranged in the rear side of a fused salt box body. When the thermal load is large or the temperature of the fused salt is low, an inner air duct is opened to increase heat release of the electric heater. When the thermal load is small or the temperature of the fused salt is high, an outer air duct is opened. Rock wool thermal insulation materials are filled between the outer side of the outer air duct and the outer shell of a machine body and between the front side of the fused salt box and the front side of the machine body. The rock wool thermal insulation materials are used for preventing excessive heat loss. Not only is running cost of the electric heater reduced, but also power grid peak valley is eased.

The specific embodiment
Shown in Fig. 1,2,3,4, a kind of fused salt accumulated electric heater, comprise by fore shell 1, back cover 2, top cover 10, the housing that base plate 4 assembling of castor 3 constitutes is installed, whole housing is stainless steel, right-hand member at the housing top cover is provided with guidance panel 5, power switch is arranged on the guidance panel, be used for the unlatching of control electric heater; Microcomputer controller is used for the configuration switch machine time.Be air outlet 6 in the upper end of fore shell, air outlet is the shutter form, and wind enters from the base plate slit, is flowed out by air outlet via interior air channel 7 or 8 backs, outer air channel.Be provided with wall bracket 11 at back cover, be used for fixedly electric heater.Be provided with blower fan 12 at organism bottom, it is installed on the blower fan fixed head 13.Body center is the fused salt case 15 that is full of fused salt 14, and the fused salt case also all is stainless steel, and fused salt case center is arranged side by side with two serpentine heating pipes 16, is fixed on the top cover of fused salt case, and heating power is respectively 800W.All be filled with rock wool heat-preservation material 17 in fused salt case front side and body front side, be used for preventing that excessively scattering and disappearing of heat from reaching the temperature that reduces housing outer surface, prevent from scalding.4 places are equipped with power line 18 at the housing base plate, and power line is with the glass fiber protective sleeve outward, and it is aging to prevent that high temperature from causing power line.At top cover 10 temperature controller 19 is installed, is used for monitoring and controlling the heating-up temperature of whole process.Be connected to reinforcement 20 at fused salt case 15 front and back face down bondings, be that symmetry axis has evenly been arranged 7 stainless steel stiffening pieces with the electric heater center line, ability for increasing fused salt case opposing thermal stress, be staggeredly arranged up and down, prevent from hindering flowing of fused salt, described blower fan 12 is opened when thermic load reduces than big or temperature of molten salt, strengthen the heat convection of electric heater and room air, to meet the demands.Wind deflector 9 is used for regulating the flow direction of wind, and when big or temperature of molten salt was low when thermic load, wind deflector 9 pushed 8 places, outer air channel, opens interior air channel 7, and when less or temperature of molten salt was higher when thermic load, wind deflector 9 pushed interior 7 places, air channel, opens outer air channel 8.Heating tube 16 is at 20:00---and 08:00 opened in the time in second day, was used for the heating fused salt.08:00---20:00 stops in the time by day, and the heat that utilizes fused salt to renew heats.
Operation principle:
Open switch, connect power supply, set the electric heater open and close time by the microcomputer controller on the guidance panel, open the heating tube switch, heating tube is started working, constantly emit heat, will to be increased to preset temperature maximum heating temperature commonly used be about 450 ℃ to temperature of molten salt in the default available machine time, and this moment, heating tube quit work automatically.As time goes on, fused salt is externally heat radiation constantly, when early stage, temperature of molten salt was higher, mainly the heat loss through radiation by the hull outside surface heats, if thermic load is big or when needing quick rising indoor temperature, can open blower fan, realize above purpose by the heat convection that strengthens air.When temperature is reduced to preset temperature, open blower fan, wind deflector is pushed interior air channel, starts working in outer air channel, and outer air channel is near hull outside, the interior air channel of temperature decreases, air enters from the space of housing bottom, through outside the air channel flow out from air outlet after being heated, heat is taken to indoor, realize the purpose of heating, when temperature further reduces, wind deflector is pushed outer air channel direction, start working in interior air channel, interior air channel is near the fused salt case outside, temperature increases in outer air channel to some extent, and air enters from the space of housing bottom equally, flows out from air outlet after interior air channel is heated, heat is taken to indoor, realize the heating purpose.The rock wool heat-preservation cotton of filling between fused salt case and housing had both prevented that the too fast of heat scattered and disappeared, and also the hull outside surface temperature was reduced to the temperature that human body can bear, and prevented the generation of scald accident.
