Definitions
- the present invention relates to a combination cooling and heating fan structure, and more particularly to a combination cooling and heating fan structure that can limit a driving device and a fan blade assembly thereof to rotate at a reduced rotational speed when a heating device of the fan structure is started to produce hot air.
- the currently commercially available dual fan cooler and heater includes a heating device, which heats air surrounding it to produce hot air, and a fan blade assembly, which rotates to blow the produced hot air through an indoor environment to gradually increase the temperature of the indoor environment. It is noted the rotational speed of the fan blade assembly will indirectly extend or shorten the time needed to increase the indoor temperature. When a user increases the rotational speed of the fan blade assembly to enhance air convection in the indoor environment, the temperature of the produced hot air will inevitably reduce more quickly, and more time is needed to increase the indoor temperature.
- a primary object of the present invention is to provide a combination cooling and heating fan structure, which is able to limit a driving device thereof to rotate within a specific rotational speed range when the fan structure blows hot air in an indoor environment, so as to effectively avoid quick loss of heat energy of the hot air and to shorten the time needed to increase the temperature of the indoor environment.
- the combination cooling and heating fan structure includes a driving device, a heating device and an electronic device.
- the driving device drives a fan blade assembly to rotate; the heating device is able to produce hot air; and the electronic device is electrically connected to the driving device and the heating device and includes a regulating unit, a processing unit and a limiting module.
- the regulating unit of the electronic device can control the driving device to rotate within a preset first rotational speed range to thereby drive the fan blade assembly of the fan structure to rotate and cause cold convection.
- the regulating unit can also selectively increase or reduce the rotational speed of the driving device within the first rotational speed range.
- the processing unit of the electronic device can control the heating device to produce hot air.
- the limiting module of the electronic device can limit the driving device to rotate within a second rotational speed range, which is smaller than the first rotational speed range, so that the fan blade assembly blows the produced hot air to cause heat convection.
- the limiting module includes a speed-limiting unit and a current-dividing unit.
- the speed-limiting unit is electrically connected to the driving device for limiting the driving device to rotate at a speed within the second rotational speed range.
- the current-dividing unit is electrically connected to the processing unit, the regulating unit, the speed-limiting unit and the heat device for selectively transmitting an external power supply to only the regulating unit or to both of the speed-limiting unit and the heating device. And, the speed-limiting unit and the current-dividing unit together form the limiting module.
- the processing unit generates a first control signal to the current-dividing unit when only the driving device is started, so that the current-dividing unit having received the first control signal transmits the external power supply to only the regulating unit.
- the processing unit generates a second control signal to the current-dividing unit when both of the driving device and the heating device are started, so that the current-dividing unit having received the second control signal transmits the external power supply to both of the speed-limiting unit and the heating device.
- the limiting module includes a suppressing unit and a current-dividing unit.
- the suppressing unit is electrically connected to the regulating unit and the processing unit for suppressing the regulating unit, so that the regulating unit can increase or reduce the rotational speed of the driving device only within the second rotational speed range.
- the current-dividing unit is electrically connected to the regulating unit and the heating device for selectively transmitting an external power supply to only the regulating unit or to both of the regulating unit and the heating device. And, the suppressing unit and the current-dividing unit together form the limiting module.
- the processing unit generates a first control signal to the current-dividing unit, so that the current-dividing unit starts only the driving device via the regulating unit and limits the driving device to rotate at a speed within the first rotational speed range.
- the processing unit generates a second control signal to both of the current-dividing unit and the suppressing unit, so that the driving unit rotates at a speed within the second rotational speed range and the heating device is driven to produce hot air.
- the current-dividing unit and the processing unit together constitute a microprocessor.
- the combination cooling and heating fan structure further includes a wireless receiver module electrically connected to the electronic device and a sensing device electrically connected to the electronic device.
- the wireless receiver module is wirelessly connected to a portable mobile device, so that the portable mobile device can remotely start the driving device and the heating device via the wireless receiver module.
- the sensing device detects different physical quantities in an indoor environment.
- the electronic device is caused to turn off the driving device and the heating device when the sensing device detects any specific physical quantity is higher or lower than a preset value.
- the sensing device includes a temperature sensor unit for sensing an indoor temperature and a humidity sensor unit for sensing an indoor humidity level. The electronic device stops the driving device and the heating device from operating when the temperature sensor unit detects an indoor temperature that is too high relative to a corresponding preset value or the humidity sensor unit detects an indoor humidity level that is too low relative to a corresponding preset value.
- the driving device includes an oscillating assembly for causing the fan blade assembly to oscillate, and the electronic device is able to selectively control the oscillating assembly to oscillate the fan blade assembly.
- the first and the second rotational speed range have the same low limit while the first rotational speed range has a high limit larger than that of the second rotational speed range.
- the present invention is characterized in that, when the driving device and the heating device are started simultaneously, the limiting module of the electronic device limits the driving device to rotate within the second rotational speed range for the fan blade assembly to blow hot air through an indoor environment and cause heat convection, which can effectively increase the temperature of the indoor environment while preventing quick loss of thermal energy during the heat convection.

- the housing 20 internally defines a receiving space 21 communicable with an environment outside the housing 20 .
- a starting device 30 In the housing 20 , there are mounted a starting device 30 , a driving device 40 , a heating device 50 , an electronic device 60 , and a fan blade assembly 70 .

- the heating device 50 is mounted in the receiving space 21 to locate in front of the fan blade assembly 70 . Further, the heating device 50 is able to heat air inside the receiving space 21 to produce hot air.
- the electronic device 60 mainly includes a limiting module 61 , a processing unit 62 , an AC-to-DC converter 63 , and a regulating unit 64 .
- the limiting module 61 is composed of a current-dividing unit 611 and a speed-limiting unit 612 .
- the current-dividing unit 611 is electrically connected to the processing unit 62 , the AC-to-DC converter 63 , the regulating unit 64 , the speed-limiting unit 612 and the heating device 50 .
- the speed-limiting unit 612 is connected to the driving device 40 .
- the processing unit 62 is electrically connected to the starting device 30 for receiving the driving start signal and the heating start signal. In the case only the driving start signal is received, the processing unit 62 generates a first control signal to the current-dividing unit 611 . On the other hand, in the case both of the driving start signal and the heating start signal are received, the processing unit 62 generates a second control signal to the current-dividing unit 611 . In a preferred embodiment of the present invention, the processing unit 62 and the current-dividing unit 611 together constitute a microprocessor 65 .
- the regulating unit 64 is electrically connected to the driving device 40 , while the AC-to-DC converter 63 is electrically connected to the current-dividing unit 611 of the limiting module 61 to receive an external AC power supply.
- the AC-to-DC converter 63 functions to convert the external AC power supply into an external DC power supply and transmit the external DC power supply to the current-dividing unit 611 of the limiting module 61 .
- the current-dividing unit 611 selectively transmits the received external DC power supply to only the regulating unit 64 or to both of the speed-limiting unit 612 of the limiting module 61 and the heating device 50 .
- the regulating unit 64 when receiving the external DC power supply, transmits the external DC power supply to the driving device 40 , so that the fan blade assembly 70 is driven by the driving device 40 to rotate in the receiving space 21 and accordingly cause air therein to flow.
- the regulating unit 64 can selectively increase or reduce a rotational speed of the driving device 40 within a first rotational speed range. In the illustrated first preferred embodiment, the regulating unit 64 achieves the increase or reduction of the rotational speed of the driving device 40 by changing the resistance of the driving device 40 ; and the driving device 40 is controlled by the regulating unit 64 to rotate at a speed ranged between 30 and 1400 rpm.
- the speed-limiting unit 612 When the speed-limiting unit 612 receives the external DC power supply, it transmits the received external DC power supply to the driving device 40 , so that the driving device 40 drives the fan blade assembly 70 to rotate in the receiving space 21 and accordingly cause air therein to flow.
- the speed-limiting unit 612 can limit the driving device 40 to rotate within a second rotational speed range, which is smaller than the first rotational speed range.
- the first and the second rotational speed range have the same low limit while the first rotational speed range has a high limit larger than that of the second rotational speed range.
- the speed-limiting unit 612 limits the driving device 40 to rotate within the second rotational speed range by limiting the resistance of the driving device 40 to change within a specific resistance range.
- the driving device 40 is controlled by the speed-limiting unit 612 to rotate at a speed ranged between 30 and 300 rpm.
- the processing unit 62 When receiving the driving start signal only, the processing unit 62 generates the first control signal to the current-dividing unit 611 of the limiting module 61 .
- the current-dividing unit 611 of the limiting module 61 transmits the external DC power supply to the driving device 40 via the regulating unit 64 , so that the fan blade assembly 70 is driven by the driving device 40 to rotate in the receiving space 21 and accordingly causes air therein to flow, which causes cold convection to thereby reduce the temperature of an indoor environment.
- the regulating unit 64 When the driving start switch 31 is turned to different magnitudes of rotational speed, the regulating unit 64 will correspondingly cause changes in the rotational speed of the driving device 40 to increase or reduce an air flow rate of the cold convection.
- the driving start switch 31 is turned to a rotational speed of 600 rpm, and the regulating unit 64 correspondingly drives the driving device 40 to rotate at a speed of 600 rpm.
- the driving start switch 31 and the heating start switch 32 are turned on at the same time, so that the driving start switch 31 generates the driving start signal to the processing unit 62 while the heating start switch 32 generates the heating start signal to the processing unit 62 .
- the processing unit 62 receives both of the driving start signal and the heating start signal, it generates the second control signal to the current-dividing unit 611 of the limiting module 61 .
- the current-dividing unit 611 of the limiting module 61 transmits the external DC power supply to the speed-limiting unit 612 and the heating device 50 at the same time.
- the speed-limiting unit 612 further transmits the received external DC power supply to the driving device 40 for the latter to drive the fan blade assembly 70 to rotate in the receiving space 21 . And, the rotation of the fan blade assembly 70 causes indoor air to flow.
- the heating device 50 when the heating device 50 receives the external power supply, it starts heating the air in the receiving space 21 to produce hot air, which is blown by the fan blade assembly 70 into the indoor environment to cause heat convection to thereby increase the temperature of the indoor environment. Since the speed-limiting unit 612 can limit the driving device 40 to rotate within the second rotational speed range, the driving device 40 will drive the fan blade assembly 70 to rotate at a low speed and slowly blows the produced hot air into the indoor environment, which effectively prevents quick loss of thermal energy during the heat convection and shortens the time needed to increase the indoor temperature.
- the speed-limiting unit 612 limits the driving device 40 to rotate at a speed ranged between 30 and 300 rpm, so that the driving device 40 drives the fan blade assembly 70 to rotate at a speed ranged between 30 and 300 rpm.

- the current-dividing unit 611 of the limiting module 61 when it receives the first control signal, it transmits the external DC power supply to only the regulating unit 64 , which controls the driving device 40 to drive the fan blade assembly 70 to rotate within the first rotational speed range.

Meanwhile, when the suppressing unit 613 receives the second control signal, it suppresses the regulating unit 64 , so that the regulating unit 64 drives the driving device 40 to rotate only at a speed within the second rotational speed range, bringing the fan blade assembly 70 to also rotate within the second rotational speed range.
- a combination cooling and heating fan structure 1 according to a third preferred embodiment of the present invention is different from the first one in that the starting device 30 thereof further includes a wireless receiver module 80 , which is electrically connected to the processing unit 62 .
