Description

Air supply device and mode control method for air supply device
Technical Field
The present invention relates to an air blower and a mode control method for the air blower, and more particularly, to an air blower that can use an external power supply and a rechargeable battery as power supply sources, and a mode control method for the air blower.
Background
Generally, an electric fan is a device that rotates predetermined blades by using an electric motor to send wind in a selected direction. The wind passing through such an electric fan generates a flow of air and performs a function of cooling a person or a room by taking heat from the person.
Such an electric fan does not substantially perform a function of ventilating or purifying air since it operates to circulate indoor air, which is the same in the case of an air conditioning apparatus such as an air conditioner.
The electric fan circulating air indoors as described above has a limitation in that indoor pollutants are circulated together because only a simple air flow is generated, and further air quality is degraded because dust and impurities existing indoors are scattered due to the generation of the air flow.
With the recent increase in air pollutants, the problem of the atmospheric environment has become a social problem. In particular, it is known that a sandstorm and mote which flow from the wind of chinese province in spring cause respiratory diseases such as bronchitis and asthma, and cardiovascular and cerebrovascular diseases. Therefore, it is the current situation that the utilization rate of the air cleaner as an electric appliance in spring is increasing.
In addition, in order to improve the living environment, a warm air blower that can supply warm air is used in winter.
That is, most of the households mainly use an air cleaner for purifying air in spring and winter, use an electric fan in summer, use a heater unit in winter, and the like, and thus have three products of an air cleaner, an electric fan, and a heater unit, and use them as seasonal home appliances, respectively, so that it is troublesome to arrange a plurality of devices, and the storage time is longer than the use time, and the utilization rate of the devices is low, and various devices are expensive, thus having a problem of low economic efficiency.
Accordingly, recently, a blowing device capable of providing functions of an electric fan, a fan heater, and an air cleaner in one device is being developed.
In addition, such a blower needs to be supplied with power in order to rotate a predetermined blade by the operation of a motor to blow air in a selected direction, and further, needs to be supplied with power in order to generate heat for a heater operated to generate warm air.
In this case, an external power supply is basically available as a power supply source, and a built-in rechargeable battery may be additionally used in the case of a small-sized home appliance in which mobility is important.
However, when used as a fan heater, the power supply from the rechargeable battery is not suitable for safety reasons or may have a problem that the capacity of the rechargeable battery is insufficient compared to the power consumption of the heater.

Further, the air supply device 1 may further include a filter portion 14, and the filter portion 14 is disposed on the air moving passage and is configured to filter particles in the air passing through the air moving passage.
The case 10 may be composed of an upper case 10a and a lower case 10b combined with the exhaust port side front grill 11, so that the case 10 may be opened to replace parts (e.g., blower parts) inside the case 10 or used when assembling or disassembling a function expanding module that provides an additional function to the blower according to user's convenience, as shown in fig. 2.
The holder 20 supports a lower portion of the blower 1, and is configured to tilt the blower 1 in the vertical direction or to reciprocate in the horizontal direction.
Although not shown in the drawings, a control circuit unit for controlling the air blowing unit 13 and the heat generating unit 12 may be provided in the casing 10, particularly in the holder 20, and such a control circuit unit is preferably disposed in a space in the casing 10 in which a driving motor of the air blowing unit 13 is particularly disposed or in a position adjacent to the space.
The support 30 is used for applying an external power source to the air blower 1, and a power supply unit is provided on the upper surface of the support 30 and connected to the external power source. When the air blowing device 1 is mounted on the support base 30, a power supply connection portion (not shown) provided on the bottom surface of the air blowing device 1 is connected to the power supply portion, and external power is supplied to the air blowing device 1.
In addition, a rechargeable battery for supplying power to the air blowing device 1 may be provided on the stand 20. Thus, in a state where the air blower 1 is mounted on the support base 30, the air blower 1 or the rechargeable battery can be driven by the external power supplied through the support base 30, and in a state where the air blower 1 is separated from the support base 30, the air blower can be driven by the power charged in the rechargeable battery. In addition, the power supply portion may be formed to protrude upward from the center of the upper surface of the support base 30, and the power supply connection portion may be formed to be recessed in the center of the bottom surface of the air blowing device 1 so that the power supply portion can be inserted.

Here, in the mode, as shown in fig. 2, the blowing unit 13 is disposed in an air moving passage connecting the air intake unit and the air exhaust unit in the casing 10, and as the driving motor of the blowing unit 13 rotates the blowing fan while receiving power from the power supply source, the outside air of the casing 10 flows into the air intake unit and is exhausted to the air exhaust unit through the air moving passage (blowing mode).
In the air moving passage, the filter 14 is provided between the air suction part and the air blowing part 13 to filter particles or impurities in the air flowing in from the air suction part, thereby discharging clean air (air cleaning mode), or the heating part 12 provided between the air discharge part and the air blowing part 13 is operated to heat the air passing through the air blowing part 13, thereby discharging warm air (warm air mode), etc., so that the air blowing part, the heating part, and the filter can be selectively arranged or operated on the air moving passage in the case 10 to realize different modes.
In addition, when the blower 13, the heat generating unit 12, and the filter 14 are all installed and operated, the clean air from which contaminants are removed can be used in a warm air-air cleaning mode in which the clean air is discharged in a warm heated state.
Fig. 5 is a block diagram of an air supply apparatus according to an embodiment of the present invention, which is capable of using an external power source and a rechargeable battery as power supply sources.
As described above, the blower device of the present invention can use the external power supply 30 and the rechargeable battery 21 as the power supply sources, and in particular, the driving motors of the heat generating unit 12 and the blower unit 13 receive power from the external power supply 30 or the rechargeable battery 21 as the power supply source and operate.
As described above, the control unit 22 may be included in the casing 10, particularly, in the control circuit unit provided inside the holder 20 for controlling the air blowing unit 13 and the heat generating unit 12, and the control unit 22 determines whether or not the rechargeable battery is used as the power supply source when the air blowing device is operated, and controls the operation to be in a mode selected from the restricted operable modes by restricting the operable mode by at least one of the first mode in which the heat generating unit 12 is required to operate and the second mode other than the first mode in which the air blowing unit 13 is required to operate.
As will be described in further detail below, when it is determined that the rechargeable battery is used as the power supply source, the control portion 22 may exclude the first mode in which the heat generating portion needs to be operated from the operable modes for safer and more stable operation. In this case, the first mode may be a warm air mode in which the air blowing unit and the heat generating unit are required to operate, and the second mode may be an air blowing mode in which the heat generating unit is not required to operate but only the air blowing unit operates or an air cleaning mode in which the air blowing unit and the filter unit operate.
At this time, when determining that the rechargeable battery is used as the power supply source, the control section 22 may control the first mode not to be displayed as the operable mode to be excluded from the selection range. For example, the air blowing mode and the air cleaning mode that change in accordance with the cycle of pressing the selection/input button of the mode display unit 42 are visually displayed. In this case, the visual display may be displayed by a single small LED alongside the mark indicating each mode.
Alternatively, the air blowing mode, the air cleaning mode, and the non-selection of the mode are visually displayed, which change in accordance with the cycle of pressing the selection/input button of the mode display unit 42. In this case, the visual display may be displayed by a single small LED aligned with a mark indicating each mode, and any small LED may not be turned on when the mode is not selected. Thus, the mode that the user can not select is not displayed as the operable mode and is automatically excluded from the selection range, and thus the effort, time, and the like related to the selection are eliminated, facilitating the use of the user.
In addition, the control unit 22 may control the inside of the blower to be sterilized by the ultraviolet-a LED provided in the casing 10. Further, it may be controlled to measure the concentration of the fine dust using a particle sensor provided on a side of the casing 10, for example, not the side provided with the display portion 40 but on the other side, and to display a color corresponding to the measured concentration of the fine dust on the air status indicator lamp 10c shown in fig. 1. The operation of the control unit is generally performed regardless of whether an external power source or a rechargeable battery is used as a power source, but may be performed in conjunction with the present invention to determine whether to operate, if necessary.
Fig. 6 is a flowchart of a mode control method for an air-blowing device capable of using an external power supply and a rechargeable battery as power supply sources according to another embodiment of the present invention. Here, the detailed operations and effects in the respective steps, which are the same as those already mentioned in the description of the air blowing device, are omitted.
Referring to fig. 6, a method of controlling a mode of an air blowing device capable of using an external power supply and a rechargeable battery as power supply sources begins with a step of preparing the air blowing device (S10), the air blowing device including: a housing provided with an air moving passage for connecting an air suction port and an air discharge port; an air supply part which is configured on the air moving channel and is used for forming air flow from the air suction port to the air exhaust port; and a heating part arranged on the air moving channel for heating the air passing through the air moving channel. If the power of the air blowing device is turned on using the external power or the rechargeable battery as the power supply source (S20), a step of determining whether or not the rechargeable battery is used as the power supply source is performed (S30).
Then, the step of limiting the operable mode by at least one of a first mode requiring the operation of the heat generating unit and a second mode other than the first mode requiring the operation of the air blowing unit is executed. This step is further specifically described below. If it is determined in the previous step that the rechargeable battery is used as the power supply source, the step of removing a part of all modes from the operable mode (S40), that is, the step of removing the first mode from the operable mode, is performed. If it is determined in the preceding step that the external power source is not used as the power source, instead of the rechargeable battery, the step of identifying all modes as the operable mode (S50) is performed, that is, the first mode and the second mode are both set as the operable mode, and the first mode is not excluded from the operable mode.
Finally, step S60 of operating in a mode selected from the restricted operable modes is executed, and the mode control method of the air blowing device is ended.
In this way, in the blower apparatus capable of using the external power supply and the rechargeable battery as the power supply sources, the operable mode is restricted according to the type of the power supply source, and therefore, safe and stable operation can be ensured. Further, the mode excluded from the operable modes is not displayed as the operable mode and is thereby excluded from the selection range, so that the convenience of the user can be improved.
In general, terms used in this specification are generally intended to be interpreted as "open" terms, especially in the claims (e.g., the body of the claims) (e.g., "comprising" should be interpreted as "including but not limited to," "having" should be interpreted as "having at least the above," and "includes" should be interpreted as "includes but is not limited to"). When a specific number is set forth in a claim recitation, such an intent is explicitly recited in the claim, and if not so, it is to be understood that such intent is not present.
Only certain features of the invention have been illustrated and described in this specification, but various modifications and changes may occur to those skilled in the art. It is therefore to be understood that the appended claims are intended to cover all such changes and modifications as fall within the true spirit of the invention.
