Description

Electric device with fan module{ELECTRIC APPARATUS COMPRISING A FAN MODULE}

The present specification relates to an electric device having a fan module.

An electric device having a fan module may be used in a drying device (or dryer) or a dust collector (or vacuum cleaner). For example, the drying device may be used to dry the wet hair of a person or of a companion animal (or pet) by spraying hot or cold air. In addition, the dust collecting device may be used to collect dust, hair, or foreign matter by using a dust collecting force (or suction force) generated by rotation of the fan module.

The air may be blown toward the nozzle 500 through the blowing path 146.

The heater module 150 may heat air discharged toward the air outlet according to the rotation of the blowing fan 133.

The heater module 150 according to the first example is disposed to surround the driving motor 131 of the fan module 130 to rapidly increase the temperature of the wind (or air) blown toward the nozzle 500 by the fan module 130 To generate hot air. The heater module 150 is disposed between the first guide member 141 and the second guide member 143 of the blowing guider 140 to dissipate heat on the blowing path 146 by the fan module 130. The wind blown through the blowing path 146 may be heated.

The heater module 150 may be implemented to rapidly generate heat or cool rapidly by an applied heater power source (or heater voltage). The heater module 150 according to an example may be rapidly heated or rapidly cooled within a range of 2 seconds to 5 seconds. For example, the heater module 150 may be heated to about 200 degrees for 2 seconds to 5 seconds or cooled to less than 10 degrees in a heated state. Here, for 2 seconds to 5 seconds, the heating temperature (or heating temperature) of the heater module 150 may be changed according to the voltage and/or current level of the applied heater power. For example, the magnitude of the voltage and/or current of the heater power source may be set such that the initial heating time of the heater module 150 is 5 seconds or less, more preferably 3 seconds or less.

The heater module 150 may be implemented to generate a noise of about 60dB to 70dB in the electric device according to the frictional sound generated by friction with the wind blown through the blowing path 146.

The heater module 150 according to an example may include a first heat shield member 151, a second heat shield member 153, and a heating member 155.

The first heat-blocking member 151 is implemented to surround the driving motor 131 of the fan module 130 to block heat generated by the heat generation of the heating member 155 from being transferred to the driving motor 131. In this way, it is possible to prevent damage to the driving motor 131 due to heat. The first heat shield member 151 according to an example may be disposed to surround the second guide member 143 of the blowing guide 140. For example, the first heat shield member 151 is implemented in the form of a cylindrical tube and is disposed between the first guide member 141 and the second guide member 143 of the blowing guide 140, and the blowing guide 140 It may be disposed close to the second guide member 143 of.

The first heat shield member 151 according to an example may include mica. For example, the first heat shield member 151 may include muscovite, phlogopite, biotite, or synthetic mica. In this case, synthetic mica may contain fluorine instead of hydroxide ions present in natural mica. When the first heat-blocking member 151 includes biotite, the first heat-blocking member 151 emits far-infrared rays, thereby providing an effect according to the far-infrared rays to a user or companion animal.

The second heat shield member 153 is implemented to surround the first heat shield member 151 so that heat generated by the heat generation of the heat generating member 155 is transferred to the first case 110 and the second case 130. It is possible to block transmission, thereby preventing thermal deformation or heating of the first case 110 and the second case 130 due to heat. The second heat shield member 153 according to an example is disposed between the first guide member 141 and the first heat shield member 151 of the blowing guide 140, and the first guide member of the blowing guide 140 It can be placed close to 141.

The second heat shield member 153 according to an example may include mica. For example, the second heat shield member 153 may be made of the same material as the first heat shield member 151.

The heat generating member 155 is disposed between the first heat shield member 151 and the second heat shield member 153 and is blown toward the nozzle 500 by the fan module 130 by heating according to the applied heater power. It can heat up the wind (or air) rapidly. The heating member 155 may be implemented to rapidly generate heat by the applied heater power (or heater voltage) or to be rapidly cooled when the heater power (or heater voltage) is cut off. For example, the heating member 155 may glow red within 2 to 5 seconds from the time when the heater power is applied by the applied heater power to emit heat. The heating member 155 may be expressed as a heating element or a heating strip.

The heating member 155 according to an example may be rapidly heated or rapidly cooled within a range of 2 seconds to 5 seconds. For example, the heating member 155 may be heated to about 200 degrees for 2 seconds to 5 seconds or cooled to less than 10 degrees in a heated state. Here, the heating temperature (or heating temperature) of the heating member 155 for 2 seconds to 5 seconds may be changed according to the voltage and/or current level of the applied heater power source. To this end, the heating member 155 according to the present specification is implemented with a thin metal material having a thickness of 0.02 mm to 0.1 mm, so that rapid temperature increase and rapid cooling are possible, and the elevated temperature is kept constant without increasing the temperature due to accumulated heat. I can. For example, the heating member 155 may have a shape of a thin film strip (or thin film plate) made of stainless steel instead of a coil made of nickel chromium wire.

When the heating member 155 according to an example has a thickness exceeding 0.1mm, the initial heating time increases, and as the heating time increases, the heating temperature gradually increases due to the accumulated heat, so that the heating temperature or the raised temperature is constant. Difficulty maintaining or controlling them. In addition, when the heating member 155 has a thickness of less than 0.02 mm, problems due to the initial heating time and heat accumulation are improved, but may be damaged during the assembly (or module) process of the electric device due to the relatively thin thickness. That is, as the heating member 155 has a thinner thickness, there is an advantage in that the initial heating time and the problem due to heat accumulation can be improved, but there is a disadvantage in that it may be damaged during the assembly (or module) process of the electric device. Therefore, the heating member 155 may have a metal plate shape made of stainless steel having a thickness of 0.02mm to 0.1mm, but considering the advantages and disadvantages according to the thickness, the heating temperature, and the accumulated heat, the heating member 155 is 0.04mm. It is preferable to have a metal plate shape made of stainless steel having a thickness of to 0.08mm and a width of 1.5mm or more. According to the experiment, it was confirmed that when 9V heater power was applied to the heating member 155 having a thickness of 0.04mm for 10 minutes, the heating member 155 maintained a constant temperature of about 200 degrees.

The heating member 155 according to an example may include a plurality of fixing portions 155a, a first power terminal T1, and a second power terminal T2.

Each of the plurality of fixing portions 155a may be formed on the heating member 155 to have a predetermined interval. For example, each of the plurality of fixing parts 155a may protrude from the heating member 155 to a predetermined height.

The first power terminal T1 may be electrically coupled to one end of the heating member 155. The first power terminal T1 may receive the first heater power. For example, the first power terminal T1 may receive a DC voltage of positive polarity (+).

The second power terminal T2 may be electrically coupled to the other end of the heating member 155. The second power terminal T2 may receive second heater power. For example, the second power terminal T2 may receive a negative DC voltage.

The heating member 155 is rapidly heated by a current flowing according to the first heater power applied to the first power terminal T1 and the second heater power applied to the second power terminal T2 to release heat. I can.

The heater module 150 according to an example may further include a heater support member 157 for supporting the heating member 155.

The heater support member 157 may be disposed between the first heat blocking member 151 and the second heat blocking member 153 to support the heating member 155. The heater supporting member 157 according to an example may include a plurality of heater supporting portions for supporting the heating member 155.

Each of the plurality of heater support parts may support each of the plurality of fixing parts 155a formed on the heating member 155. Each of the plurality of heater support portions according to an example may include a first support portion 157a and a second support portion 157b parallel to the first support portion 157a.

Each of the first support part 157a and the second support part 157b may support a corresponding fixing part 155a among a plurality of fixing parts 155a formed on the heating member 155. Each of the first support part 157a and the second support part 157b according to an example has a length and width set from the lower surface of the heater support member 157 so as to be parallel to each other along the height direction Z of the heater support member 157 It may include a slit shape formed by. For example, each of the first support portion 157a and the second support portion 157b may include a stepped slit shape having a stepped portion for fixing or supporting the heating member 155.
