The present invention relates to a wireless cleaner, to control the battery charging of the wireless cleaner.

In general, the user mounts the wireless cleaner used in the cradle after using the wireless cleaner. In addition, the cradle of the wireless cleaner usually serves as a charger.

Therefore, when the wireless cleaner is not used, that is, in a mounted state, the battery of the wireless cleaner may be charged. Accordingly, when the user does not use the wireless cleaner for a predetermined period of time, the battery is fully charged and remains fully charged. This is because the size of the battery provided is limited due to the characteristics of the wireless cleaner which is easy to move and can carry, so that the user can ensure the maximum use time when using the wireless cleaner. Therefore, the battery of the wireless cleaner can be charged and maintains a full charge state even though the wireless cleaner has sufficient battery power as the user uses the wireless cleaner for a short time.

However, in general, charging of a battery is a process of generating a charge difference between anodes through oxidation and reduction. And the battery restricts the movement of the charge on the cathode through the internal structure. Therefore, when the charging proceeds, the electric pressure applied to the internal structure of the battery is increased by the electric charge difference, that is, the voltage. Therefore, as charging progresses and the voltage to be charged increases, deterioration of the internal structure of the battery may be accelerated. Therefore, as described above, there is a problem in that the life of the battery can be drastically reduced when the battery is maintained in a fully charged state, that is, when a state having a maximum voltage difference is maintained.

1A is a block diagram illustrating the configuration of a wireless cleaner 1 according to an embodiment of the present invention. And Figure 1b is an exemplary view showing an example of the power consumption information is collected in the wireless cleaner according to an embodiment of the present invention.

First, referring to FIG. 1A, the wireless cleaner 1 according to an embodiment of the present invention is connected to the control unit 100 and the control unit 100, and the power supply unit 110 and memory controlled by the control unit 100 It may be configured to include (120), the driving unit 130, and the display unit 140. In addition, it may be configured to further include a communication unit 150. The components shown in FIG. 1 are not essential in implementing the wireless cleaner 1, so the wireless cleaner 1 described herein may have more or fewer components than those listed above. have.

First, the driving unit 130 may include various components necessary for driving the wireless cleaner 1. For example, the driving unit 130 includes a suction unit (not shown), a motor and a rotating blade for generating an air pressure difference for suctioning dust, and a dust container in which the suctioned dust is collected and the suctioned dust is returned to the outside. And a filter to prevent discharge.

In addition, the driving unit 130 may include an input unit (not shown) capable of receiving user input for executing various operations of the wireless cleaner 1. Then, the control unit 100 may control at least one of the components of the driving unit 130 to be driven according to a user input applied through the input unit.

Meanwhile, the power supply unit 110 may receive power from the battery 112 provided by the control of the control unit 100 and supply power required for the operation of each component. The battery may be a built-in battery made to be charged, and when the wireless cleaner 1 is mounted on a cradle, it may be charged through power supplied from the charging section of the cradle. Hereinafter, it is assumed that the cradle is a charging cradle including a charging unit capable of charging the battery 112 of the wireless cleaner 1.

The memory 120 may include various data for driving and operating the wireless cleaner 1. The memory 120 may store information related to a power consumption pattern of the wireless cleaner 1.

Here, the information related to the power consumption pattern may be a power consumption pattern analyzed from the power consumption information of the wireless cleaner 1 and the collected power consumption information. In addition, it may include information on the period in which the power consumption information is collected.

Meanwhile, the power consumption information may be collected by the control unit 100. For example, when the wireless cleaner 1 detects a departure from the cradle, the controller 100 may store the battery 112 charging level at that time as the 'power level before use' in the memory 120. In addition, when the wireless cleaner 1 is mounted on the cradle 160 again, the charging level of the battery 112 at that time may be stored in the memory 120 as a 'power level after use'. In addition, the difference between the pre-use power level and the post-use power level may be stored in the memory 120 as power consumption information. For example, when the power level before use is 100% and the power level after use is 80%, power consumption may be calculated and stored as 20%.

Meanwhile, at least one of the power level before use and the power level after use may be collected by a cradle on which the wireless cleaner 1 is mounted. Fig. 1B shows an example of such a case.

For example, when the user uses the wireless cleaner 1, the wireless cleaner 1 may be detached from the cradle 160 as shown in the first drawing at the top of FIG. 1B. In addition, when the wireless cleaner 1 is mounted, the charging unit 162 and the charging terminal 170 of the cradle 160 may be in contact with each other as shown in the second drawing at the bottom of FIG. 1B.

First, as shown in the first drawing of FIG. 1B, when the detachment of the wireless cleaner 1 is detected while the wireless cleaner 1 is mounted as shown in the first drawing of FIG. 1B, the battery 112 of the wireless cleaner 1 charged up to now ) Power level can be measured. For example, when fully charged, the cradle 160 may measure the power level of the battery 112 to 100%.

In this state, when the user uses the wireless cleaner 1 and then mounts the wireless cleaner 1 on the cradle 160 as shown in the second drawing of FIG. 1B, first of the wireless cleaner 1 battery 112 The residual power level can be measured. In addition, the difference between the measured power level and the measured residual power level before the wireless cleaner 1 leaves the cradle 160 may be calculated. And the calculated difference may be the power consumption while the user is using the wireless cleaner 1.

Meanwhile, when the power consumption according to the user's use is calculated, the cradle 160 may transmit it to the wireless cleaner 1. For example, the cradle 160 may be formed to allow communication with each other when the wireless cleaner 1 is mounted. Alternatively, the cradle 160 may be formed to enable wireless communication with the wireless cleaner 1. In this case, the power consumption information calculated by the cradle 160 is transferred from the cradle 160 to the wireless cleaner 1 in a state in which the wireless cleaner 1 is detached from the cradle 160, that is, being used by a user. Can be sent.

In addition, the controller 100 may control the overall operation of the wireless cleaner 1. The controller 100 may determine whether the wireless cleaner 1 is in a used state, and when it is determined that the wireless cleaner 1 is in a used state, may control the driving unit 130 to perform a cleaning function according to a user input.

For example, the control unit 100 may determine that the wireless cleaner 1 is currently in use when it leaves the cradle. On the other hand, when the wireless cleaner 1 is mounted on the cradle, it can be determined that the state is not being used. The difference between the power level of the battery 112 measured when the wireless cleaner 1 is detached from the cradle and the power level of the battery 112 measured when the wireless cleaner 1 is mounted on the cradle is used as power consumption information. Can be calculated. Accordingly, the power consumption information may be calculated and collected whenever the wireless cleaner 1 leaves the cradle 160.

Meanwhile, the control unit 100 may collect the power consumption information according to a preset period. In addition, the power consumption pattern of the wireless cleaner 1 may be analyzed based on the collected power consumption information. Here, the power consumption pattern may be calculated as a percentage (%) of power consumed by the battery 112 on average whenever the user uses the wireless cleaner 1. For example, when the user uses 20% of the power on average every time the user uses the wireless cleaner 1, the controller 100 may determine that the power consumption according to the power consumption pattern of the wireless cleaner 1 is 20%. have.

Meanwhile, when the power consumption pattern of the wireless cleaner 1 is analyzed, the controller 100 may limit the maximum charge amount according to the analyzed power consumption pattern. That is, when it is determined that the power consumption according to the power consumption pattern is 20% as described above, the controller 100 may set the maximum charge amount to a limited value of 20% from the currently set maximum charge amount. For example, if the currently set maximum charge amount is 100%, the control unit 100 may set '80% ', which is limited from 100% to 20%, as the maximum charge amount. Then, when the battery 112 is charged, the power source 110 may be controlled to be charged up to 80% of the maximum charge.

Then, when a predetermined period elapses again, the power consumption pattern is analyzed by analyzing the power consumption information collected during the period, and the maximum charge amount can be reset again according to the analyzed power consumption pattern. In this case, assuming that the currently set maximum charge amount is 80% and the power consumption according to the analyzed power consumption pattern is 20% again, '60% ', which is more limited from 80% to 20%, may be set as the maximum charge amount. .

Therefore, the control unit 100 of the wireless cleaner 1 of the present invention can avoid charging and discharging the battery 112 by avoiding a power level section in which deterioration of the battery may occur severely. That is, assuming that the user consumes an average of 20% of power, if the battery is always fully charged, charging and discharging of the battery occurs repeatedly between 80% and 100% sections, so that battery deterioration may be accelerated. And, accordingly, the life of the battery may be significantly shortened.

On the other hand, under the same assumption, the present invention can limit the maximum charge amount according to the power consumption used by the user. Therefore, during a period of time, charging and discharging is performed between 100% and 80% sections, and a power level section in which charging and discharging is performed between 80% and 60% sections may be changed. Then, since the maximum voltage charged in the battery 112 can be reduced, the electrical pressure applied to the internal structure of the battery 112 can be reduced. Therefore, the deterioration of the life of the battery 112 may be delayed, and the life of the battery 112 may be increased.

On the other hand, when the power consumption is calculated, the controller 100 may determine whether the actual wireless cleaner 1 is used according to the calculated amount of power consumption. For example, if the power consumption is not higher than a predetermined level, the controller 100 may determine that the wireless cleaner 1 is not actually used although it is removed from the cradle. In addition, when it is determined that it is not actually used, the calculated power consumption may not be included as collected power consumption information for analysis of the power consumption pattern.

Meanwhile, the display unit 140 may display the remaining power level of the current battery 112 under the control of the control unit 100. As an example, the display unit 140 may include a plurality of LEDs or a display capable of displaying images or text. In addition, the current power level of the battery 112 may be displayed based on at least one of the plurality of LEDs or characters and images displayed on the display unit.

Here, the display unit 140 may display the current power level of the battery 112 according to the ratio of the measured remaining power level of the battery 112 to the currently set maximum charge amount. In this case, the control unit 100 may control the display unit 140 to display the currently set maximum charge amount. Alternatively, the display unit 140 may display the current power level of the battery 112 as a ratio of the remaining power level to the total charge amount of the battery 112. In this case, the control unit 100 may indicate that the maximum charge amount is currently limited, thereby indicating to the user that charging over a certain level may be restricted.

Meanwhile, the wireless cleaner 1 according to an embodiment of the present invention may further include a communication unit 150. Here, the communication unit 150 may include one or more modules for performing communication with the wireless cleaner 1 and surrounding devices (for example, the cradle 160). To this end, the communication unit 150 may include at least one short-range communication module such as a Bluetooth ™, Radio Frequency Identification (RFID), or Infrared Data Association (IrDA) module.

In addition, the communication unit 150 may perform communication with a preset server including at least one wireless Internet module such as a wireless LAN (WLAN) and a wireless-Fidelity (Wi-Fi) module. In this case, the control unit 100 may transmit power consumption information collected during a predetermined period to the preset server through the communication unit 150. Then, the server may analyze the power consumption pattern according to the user's use of the wireless cleaner 1 during the predetermined period based on the collected power consumption information. In addition, the analyzed power consumption pattern may be transmitted to the wireless cleaner 1. Then, the controller 100 may limit the maximum charge amount of the battery 112 based on the power consumption according to the received power consumption pattern.

Hereinafter, a method for controlling power transmission of the wireless cleaner 1 that can be implemented in the wireless cleaner 1 configured as described above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential features of the present invention.

2 is a flowchart illustrating an operation process of limiting the maximum charge amount according to the analyzed power consumption pattern in the wireless cleaner according to an embodiment of the present invention.

Referring to FIG. 2, first, the controller 100 of the wireless cleaner 1 according to an embodiment of the present invention may first determine whether there is a preset maximum charge amount (S200). In addition, if there is no preset maximum charge amount, an initial value of the maximum charge amount may be set (S202). Here, the initial value of the maximum charge amount may be set to 100%.

Meanwhile, in step S200 or step S202, when the maximum charge amount is set, the controller 100 may limit the charge amount of the battery 112 of the wireless cleaner 1 according to the currently set maximum charge amount. That is, whenever the wireless cleaner 1 is charged after use, the charge amount of the battery 112 may be limited according to the currently set maximum charge amount. And whenever the wireless cleaner is used, power consumption can be measured. In addition, information on the measured power consumption may be collected (S204). Here, the power consumption may be measured by the cradle 160. In this case, the power consumption measured by the cradle 160 may be transmitted to the wireless cleaner 1 and collected.

Meanwhile, in step S204, the controller 100 may collect only power consumption information having a value equal to or greater than a preset size. That is, the power consumption information measured when the user detaches the wireless cleaner 1 from the cradle but remounts it without using it may not collect it.

Meanwhile, in step S204, when power consumption information is collected, the control unit 100 may determine whether a preset use period has elapsed (S206). Here, the use period may be any period determined to be most suitable through a number of experiments related to the life of the battery 112 according to an embodiment of the present invention. Alternatively, the period of use may be a period arbitrarily set by the user.

Here, the starting point of the period of use may be a point at which the maximum charge amount has been previously set. Therefore, if there is no previously set maximum charge amount, a point in time at which the initial value of the maximum charge amount is set in step S202 may be a starting point of the use period.

In addition, if the preset use period has elapsed in step S206, the controller 100 may analyze the power consumption pattern of the wireless cleaner 1 based on the power consumption information collected in step S204 (S208). . For example, in step S208, on the basis of the collected power consumption information, an average percentage of power consumed by the battery 112 is calculated every time the user uses the wireless cleaner 1 during the predetermined period. It can be a step.

Meanwhile, the collection of power consumption information in step S204 may be performed in a preset server that has received power consumption information from the wireless cleaner 1. In addition, the analysis of the power consumption pattern in step S208 may also be performed in the preset server.

In this case, the step S204 may include receiving the measured power consumption every time the user uses the wireless cleaner 1 from the wireless cleaner 1 or the cradle 160. In addition, the step S208 may include the step of analyzing the power consumption pattern by the preset server based on the power consumption amounts received in the step S204, and transmitting the analyzed power consumption pattern back to the wireless cleaner 1. have.

Meanwhile, when the power consumption pattern is analyzed in step S208, the controller 100 may change the currently set maximum charge amount based on the analyzed power consumption pattern (S210). For example, in step S210, the controller 100 may set the maximum charge amount as low as the average power consumption of the currently analyzed power consumption pattern. That is, when the currently set maximum charge amount is 80% and the average power consumption of the currently analyzed power consumption pattern is 30%, the controller 100 may set the maximum charge amount to 50%.

On the other hand, if the maximum charge amount is changed in step S210, the controller 100 may initialize the count of the usage period (S212). Then, it is possible to proceed to step S200 again. And the process from step S200 to step S206 can be performed again. In this case, since the currently set maximum charge amount is 50%, the controller 100 may limit the charge amount so that the battery 112 is not charged up to 50% or more. Then, according to the determination result of step S206, the process proceeds to step S200 again, or the process of steps S208 to S212 can be performed to change the maximum charge amount again.

On the other hand, in the above description, it has been determined whether or not a preset use period has elapsed in step S206, but the step S206 is a process of determining whether the number of charge / discharge cycles of the wireless cleaner 1 battery 112 exceeds a preset number of days. You can. In this case, when charging / discharging is performed more than a preset number of times according to the currently set maximum charge amount, the controller 100 proceeds to steps S208 and S210 to analyze the power consumption pattern again, and determines the maximum charge amount according to the analyzed power consumption pattern. You can change it.

3 is an exemplary view showing an example in which the power consumption section is changed according to the limitation of the maximum charge amount in the wireless cleaner 1 according to the embodiment of the present invention.

First, the graph 300 illustrated in FIGS. 3A and 3B shows the power level of the battery 112 expressed as a percentage. In addition, the first section 310 represents a power level section when charging is close to 100%, and the second section 320 represents a power level section when charging is about 50%. On the other hand, as described above, the higher the charging voltage, the more unstable and the longer the battery life deteriorates, so the first section 310 maintains a more stable state of the battery compared to the second section 320 As a result, the life of the battery may be less deteriorated.

Referring first to FIG. 3 (a), FIG. 3 (a) shows an example in which an initial value of a maximum charge amount is set according to an embodiment of the present invention. Here, since the initial value of the maximum charging amount is set to 100%, charging can be made up to 100%.

Meanwhile, the power consumption section 350 illustrated in (a) of FIG. 3 shows a consumption section according to the currently analyzed power consumption pattern.

In this case, as shown in (a) of FIG. 3, in order to prevent repeated charging and discharging being included in the power consumption section 350, a section in which the life of the battery is severely deteriorated, the present invention provides the maximum charge amount of the battery. , It can be limited based on the analyzed power consumption pattern. Accordingly, assuming that the amount of power consumed each time the user uses the wireless cleaner 1 is similar, as shown in (b) of FIG. 3, the power consumption section 350 gradually decreases due to the limitation of the maximum charge amount. It may be moved to a section (eg, a second section) in which the lifetime deterioration is less generated.

Meanwhile, as described above, when the process of limiting the maximum charge amount of the battery 112 based on the analyzed power consumption pattern is repeated, the maximum charge amount may be set to a predetermined level or less. For example, the remaining chargeable amount according to the currently set maximum charge amount may be less than the power consumption amount according to the currently analyzed power consumption pattern. For example, if the average power consumption according to the currently analyzed power consumption pattern is 60%, and the currently set maximum charge amount is 50%, the controller 100 may determine that the currently set maximum charge amount is set to a predetermined level or less. In this case, the control unit 100 may reset the currently set maximum charge amount to set the maximum charge amount to exceed the predetermined level or initialize the maximum charge amount.

4 is a flowchart illustrating an operation process of resetting the maximum charge amount in the wireless cleaner 1 according to an embodiment of the present invention in this case.

First, the controller 100 may determine whether the maximum charge amount changed in step S210 of FIG. 2 is equal to or less than a predetermined level (S400). Here, the predetermined level may be a predetermined power level. Or, it may be a power level corresponding to the power consumption according to the currently analyzed power consumption pattern. That is, when the power consumption according to the currently analyzed power consumption pattern is 30%, the predetermined level may be a power level of 30%.

In addition, when it is determined in step S400 that the maximum charge amount changed in step S210 of FIG. 2 is not below the predetermined level, the controller 100 may maintain the maximum charge amount changed in step S210 of FIG. 2. On the other hand, when it is determined in step S400 that the currently changed maximum charge amount is less than the predetermined level, the controller 100 may reset the maximum charge amount changed in step S210 of FIG. 2 (S402).

For example, the controller 100 may initialize the maximum charge amount in step S402. In this case, the maximum charge amount may be set to 100% again. Alternatively, the controller 100 may set the maximum charge amount to have a value equal to or greater than a preset minimum value. For example, if the maximum charge amount changed in step S210 is 40%, the controller 100 may set the maximum charge amount to a preset minimum value of 50%.

Alternatively, the controller 100 may set a maximum charge amount as a sum of a power consumption according to the currently analyzed power consumption pattern and a preset lowest value. For example, if the preset minimum value is 30% and the power consumption according to the currently analyzed power consumption pattern is 20%, the controller 100 may reset the maximum charge amount to 50% (30% + 20%).

Meanwhile, when the maximum charge amount is limited as described above, the control unit 100 may display the power level of the battery 112 according to the limited maximum charge amount in various ways. 5 is an exemplary view showing various examples of displaying a state of charge of a battery in a state in which the maximum charge amount is limited in the wireless cleaner 1 according to an embodiment of the present invention.

First, FIG. 5 (a) shows an example of a display unit 510 displaying a power level of a battery through a plurality of LEDs. In this case, the control unit 100 may emit the LED according to the ratio of the power level (remaining power amount) of the current battery 112 to the currently set maximum charge amount.

That is, in the state where the currently set maximum charge amount is set to 80%, if the current power level of the battery 112 is 60%, 4 of the 5 LEDs 512 may emit light. That is, the current power level (60%) may be displayed based on the currently set maximum charge amount (80%). In this case, the control unit 100 may further display another LED 514 indicating that the current maximum charge amount is set, thereby indicating to the user that the current maximum charge amount is limited.

Meanwhile, FIG. 5B shows an example of the display unit 520 that displays the power level of the battery as a graphic object in the form of a gauge. In this case, the controller 100 may display the power gauge 522 according to the ratio of the power level of the current battery 112 to the currently set maximum charge amount.

Therefore, if 80% of the current total battery is charged, and the currently set maximum charge amount is 80%, the power gauge 522 may be displayed at the maximum as shown in FIG. 5B. In this case, the control unit 100 may further indicate the currently set maximum charge amount, thereby indicating that the current battery charge amount is up to 80%.

On the other hand, as described with reference to (a) and (b) of FIG. 5, the display unit may display only the actual charging state of the battery, and may further indicate that the current maximum charge amount is set. Fig. 5C shows an example of such a case.

Referring to FIG. 5 (c), FIG. 5 (c) shows an example of a display unit 530 displaying a power level of a battery through a plurality of LEDs.

For example, when the currently set maximum charge amount is 80%, the control unit 100 may limit charging of 80% or more from the charge amount of all rechargeable batteries. Therefore, even when the wireless cleaner 1 is mounted on the cradle, as shown in FIG. 5 (c), the battery may not be charged more than 80%.

In this case, the control unit 100 may emit only a number corresponding to the actual charge amount of the battery, that is, four LEDs 532. In addition, another LED 534 that further indicates that the maximum charge has been made according to the currently set maximum charge amount may be further emitted to indicate to the user that the maximum charge amount is currently limited and that the maximum charge amount is set according to the set maximum charge amount.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention.
