Abstract
The utility model relates to a fan for cooling and warming. A PTC electric heating element and radiation fins are made into a circular heater which is positioned in front of the ordinary fan blades and the cool and warm air can be selected by a switch; the utility model has the advantages of fast heat generation, high heat effect, long service life and high safety.
Description
The utility model relates to a kind of cooling warm air machine.
Traditional electric fan wind that can only blow on, thereby can only use in summer, be placed winter.In recent years released a few money warm-air driers and cooling warm air machine, they adopt electric heating wire or far infrared quartz pipe as heater, and heating efficiency is not high, and the life-span falls short of.
The purpose of this utility model is to provide a kind of and can blows out cool breeze and also can blow out warm braw, and the hot blast starting is fast, thermal efficiency height, safe in utilization and cooling warm air machine that the life-span is long.
The utility model is achieved in that by some equidistant metal fins parallel to each other and constitutes the dentation radiator, two dentation radiators are fixed on " PTC " electric heating piece two sides and make fan-shaped heater, several so fan-shaped heaters constitute circular heating body, its diameter equals or is slightly larger than fan air channel diameter, circular heating body is installed in the place ahead of the fan blade of conventional fan, and the heater front also is equipped with safety enclosure." PTC " the two poles of the earth and the fan motor selector switch by separately respectively are access to power supply.When switch cut out " PTC " power supply, fan blew out cool breeze; " PTC " heating when connecting power supply, fan blows out warm braw.
Because the heating of " PTC " electric heating element is fast, electrothermal efficiency is high, so the warm braw starting is fast.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is overall structure figure of the present utility model.
Fig. 2 is the partial structurtes figure of the heater of " PTC " electric heating piece and radiating fin formation.
Fig. 3 is an electrical schematic diagram of the present utility model.
As shown in Figure 1, the utility model is installed the circular heating body (2) with the radiating fin formation by " PTC " before the fan blade of common rotary blade fan (1), and cool warm braw selector switch (3) can be installed in any position of fan drum.
Fig. 2 has provided the sixth structure of circular heating body.The radiating fin that is fixed on " PTC " electric heating piece two sides constitutes fan-shaped heater, just in time constitutes circular heating body by six such heaters, place on the air channel, circular heating body also can by more than six or the fan-shaped heater of suitable equal portions below six constitute.The diameter of circular heating body equals or is slightly larger than fan air channel diameter.
In the electrical schematic diagram shown in Figure 3, fan motor and " PTC " electric heating element are access to power supply in the lump by selector switch separately.In addition, motor and " PTC " electric heating piece also are connected to thermal cut-off separately, to guarantee safety.
Characteristics of the present utility model are that this device can blow out cool breeze, can blow out warm braw again, all can use throughout the year, and have the advantages such as the hot blast starting is fast, the thermal efficiency is high, use safety, the life-span is long.
Claims (4)
1, a kind of cooling warm air machine is made up of common electrical fan, " PTC " electric heating element, radiating fin, control switch and safety enclosure etc., it is characterized in that constituting the dentation radiator by some parallel equidistant metal fins; Two dentation radiators are fixed on " PTC " electric heating element two sides and constitute fan-shaped heater; The plurality of sector heater constitutes circular heating body; Circular heating body places the place ahead of fans.
2, cooling warm air machine according to claim 1, the diameter that it is characterized in that described circular heating body equal or are slightly larger than fan air channel diameter.
