Abstract
The utility model relates to a two-purpose cooling and warming fan with easily-separable electric heater which adopts an electric heater composed of a PTC heat-generating ceramic, a heat sink and a thermal insulating frame plate. The PTC heat-generating ceramic and the heat sink are separately and fixedly arranged on the thermal insulating frame plate. The electric heater is fixedly arranged behind the fan wing or in the front of the fan wing. When the fan works, the fan blows the hot air. When the hot air is not needed, the electric heater can be dismounted and is stored in the storage box arranged on the fan. The two-purpose cooling and warming fan with easily-separable electric heater has high efficiency, simple installation, high safety and convenient operation.
Description
The dismountable cold-hot dual purpose fan of electric heater is a kind of household electric appliance of novelty, relates to the manufacturing technology of Cold-warm fan.
At present commercially available its heating element of cold-hot dual purpose fan normally adopts resistance wire, is fixed on a certain position in the fan, though it can cold, hot two-purpose, because the employing resistance wire, so power consumption, the efficiency of heating surface are very low.Though adopt the warm-air drier power saving of PTC pottery as heating element, efficiency of heating surface height is not suitable for doing summer air-cooling fan because heating element for the big resistance of air-flow generation, therefore makes only suitable blowing hot-air and uses.
The purpose of this utility model provides a kind of fan that dismountable electric heater is housed, and becomes the warm braw fan after making fan load onto this electric heater when the need blowing hot-air, becomes air-cooling fan unload this electric heater when need are blown a cold wind over after, to improve the utilization rate of fan.In addition, electric heater is detachable, has made things convenient for the cleaning to electric heater, avoids the long-term back dust stratification that uses to reduce heating power.
The utility model is to constitute like this, some packaged electric heaters of being made up of PTC heating pottery and radiating fin are fixedly mounted on the back or the front of the fan wind wing, by fan back side back cover inhaled air, warm behind electric heater when the wind wing rotates, warm braw is sent in the rotation of the wind wing.When not needing to blow warm braw, can be collected in the depository dish that is provided with on the fan depository dish interior or that be provided with in addition after the electric heater dismounting.
The utility model has improved the utilization rate of fan owing to adopted dismountable electric heater, has made things convenient for the cleaning to electric heater, and the electric heater that unloads under the back is collected in the special depository dish, can not damage.The utility model is installed, and dismounting easily, and is safe in utilization, convenient.
Accompanying drawing is embodiment of the present utility model, wherein:
Fig. 1 the utility model front view;
Fig. 2 the utility model sectional drawing;
Fig. 3 the utility model cut-away view;
Fig. 4 electric heater schematic representation;
Fig. 5 the utility model electrical schematic diagram.
Now the utility model will be further described in conjunction with the accompanying drawings.
Among the figure, fan speed-regulating switch 1, electric heater switch 2, tutorial light 3 is installed on the fan frame and is connected with power circuit, and depository dish 4 is arranged on the bottom of fan, and wind direction ring 5 is installed in the front portion of the wind wing 7, motor 9 is fixedly mounted on the fixing frame 6, and the wind wing 7 is fixedly mounted on the rotatingshaft of motor 9.Electric heater 8 is by two partiting thermal insulation frame plates 10, electric heater power plug 11, and radiating fin 12, PTC heating pottery 13 assembles, and radiating fin 12 and PTC heating pottery 13 are provided with at interval, are fixed on the partiting thermal insulation frame plate 10.At cold day or need blow warm braw the time electric heater 8 is contained in the fan, earlier power plug 11 is inserted in the power socket 16 that is fixed on the fan frame during installation, by on screw on the electric heater 8 14 and the fan frame and fixing frame 6 on screw 17 usefulness key screw electric heaters 8 be fixed on the fixing frame 6 and fan frame at the wind wing 7 back sides, as need not blow warm braw the time, can put into depository dish 4 to electric heater 8 after the dismounting.The fan back cover is fixed on the fan frame back side by screw 15.
After the utility model is connected power supply, tutorial light 3 indications, press fan speed-regulating switch 1 as required or press fan speed-regulating switch 1 and electric heater switch 2 after, fan is blown a cold wind over or warm braw.The utility model can be provided with many grades of fan speed-regulating switches and heater button, so that to blowing a cold wind over or blowing warm braw and fully regulate.
