[Industrial applications]

 The present invention relates to a kind of a fan for both cooling and heating, and particularly refers to a structure in which a kind of electric appliance can be used as a hot fan and a cold fan.

[0002]

[Prior art]

 Although familiar air conditioners are used for both summer and winter, the cost of consumption is very high, and they are used only in fixed rooms and cannot be moved as needed, so heaters and fans are widely used. However, this is because two types of electric appliances are used and stored alternately in the summer and winter, which not only wastes the cost of consumption but also the space of the house, and the heater For example, the structure generates heat, but the hot air does not flow, and in use it does not feel warm unless you are near a heater, which is a well-known fact and a drawback that needs to be overcome It is.

The structure of the present invention generally includes a base 1, two bearings 2, a joint 3, a joint outlet 4 and some heat generating blades 5.

The main base 1 includes a base tube 11, in which an insulating sleeve 12 is mounted, and positive and negative power contacts 13 are screwed into insulating points at front and rear positions of the tube wall. The outer diameters of the two bearings 2 are equal, and the diameter of the shaft hole is one large and one small.

Since the joint 3 is formed by injection molding of plastic, a hat-shaped plate 31, a front tube 32 and a rear tube 33 are provided, and the outer diameter of the rear tube 33 is a> b> c. The conductive fins 331 and 332 are provided on the wall surface of the conductive fins 331 and 332, of which the conductive fin 331 is from the stage a to the end of the stage c and another conductive fin 332 is the stage a From the end to the end of the b-th stage, on the front surface of the hat-shaped plate 31, both facing spring contacts 311 and 312 are provided, which are separately connected to the both conducting fins 331 and 332, respectively.

A screw hole 333 is provided on the step wall surface of the post-joint pipe a, and a notch 321 is provided at a pipe opening of the front pipe 32. The joint outlet 4 is formed by plastic injection molding, and has a protruding base plate 41 and a pipe 42, in which a reinforcing aluminum pipe 43 is mounted and fixed by screws 44 on the outer wall of the pipe. In addition, circuit contacts 45 and 46 that face each other are provided in the tube 42 of the joint outlet 4.

The heat generating blade 5 is formed by laminating and fixing two aluminum alloy plates, and an electric heater 51 is mounted between the two aluminum alloy plates. Heat radiation fins 52 arranged in a shape are provided, the heat generating blades 5 are fixed to a convex body 531 on the outer wall of the aluminum alloy tube 53, and the circuit electric wires are housed in the tube. A temperature control switch 54 is connected to circuit contacts 45 and 46 in the body and is provided on the front end face of the aluminum alloy tube 53.

The above-described members of the present invention fix the base 1 to the front end of the motor 6 during assembly, and the respective end faces of the two bearings 2 are mounted in the base sleeve 12 with insulating washers 21, 22, 23. Are separately fixed by two packing sleeves copper 24, the joint rear tube 33 is inserted into the holes of both bearings, and the motor shaft 61 is passed therethrough. The joint outlet 4 is fixed in the aluminum alloy tube 53 by attaching a heat-resistant insulator 55 to the protruding base plate 41, and the heat generating blade 5 is jointed by the joint outlet 4. 3 and tightened with the notch 321 at the mouth using the set screw 44 of the reinforced aluminum tube 43, and the spring contact 3 of the joint 11 and 312 are in contact with the circuit contacts 45 and 46 in the joint outlet, and after the joint, the conductive fins 331 and 332 on the wall of the tube are also separately in contact with the front and rear shaft holes of the two bearings 2. The outer wall surface was packed with the packing sleeve copper 24, and was electrically connected to the insulating sleeve 12 and the packing sleeve copper 24 in which the screws of the positive and negative power contacts 13 on the base tube were tightened, and the temperature control switch 54 was turned on to set the temperature. Sometimes, the heat generating body 51 in the heat generating blade 5 generates heat, and the heat is radiated by the heat radiating fins 52 on both surfaces of the heat generating blade. When the motor starts, the heat generating blade 5 rotates to generate hot air, and this kind of heat is generated. The flowing hot air not only raises the indoor temperature, but also does not require the human body to approach the heat generating blades in use. Is rotated, it can be used as a general fan. If the heat-generating blades are used as a fan, the effect may be different. Therefore, when removing and cleaning the heat-generating blades before summer, replace them with general fan blades. The fan and heating blade of the fan use the same motor and are used alternately in both the summer and winter seasons, which has the effect of saving consumption costs and storage space, and can be moved as needed. is there.

The above-described present invention is constructed by assembling a motor of a general electric fan and a speed change switch as peripheral members. In order to meet the need for low-speed rotation of the heat generating blade, the speed change switch is used in the embodiment. You can add a low speed control push button.
