Description

Technical Field

[0001] Embodiments of the present disclosure relate to a cordless vacuum cleaner and a control method thereof. Background Art

[0002] A corded vacuum cleaner can perform a suction function by connecting a power plug to a power outlet during operation. On the other hand, a cordless vacuum cleaner can be charged by electric energy when on standby, and perform a suction function by using the charged electric energy during operation. Therefore, the movement of the corded vacuum cleaner may be restricted by a power line connecting the power plug and the cleaner body to each other, because when a user is using the corded vacuum cleaner, the power plug needs to be connected to a power outlet, while the movement of the cordless vacuum cleaner may not be restricted by the power line when it is being used, because when the cordless vacuum cleaner is being used, the power plug does not need to be connected to a power outlet.

[0003] The cordless vacuum cleaner may include a battery that stores charged electrical energy. The battery may be disposed at a designated portion of the cleaner body. When the capacity of the battery increases, the use time and adsorption performance of the cordless vacuum cleaner may be improved. Therefore, in terms of use time and adsorption performance, it may be advantageous to use a performance-type battery with increased capacity. On the other hand, when the capacity of the battery decreases, the weight of the battery may be reduced. Therefore, in terms of user convenience, it may be advantageous to use a lightweight battery with reduced capacity. When the cordless vacuum cleaner is used, the discharge trend of the battery may change according to the capacity of the battery. Since it is used cordlessly, the cordless vacuum cleaner requires a battery, and it is important that the installed battery can be used for a long time and safely. Summary of the invention

[0071] In an embodiment of the present disclosure, the PCB 1130 may control the adsorption motor 1110. In an embodiment, the PCB 1130 may include: a processor (hereinafter, referred to as a first processor 1131) configured to control communication with the brush device 2000; a first switch device 1132 connected to a signal line; a switch device (hereinafter, referred to as a pulse width modulation (PWM) control switch device 1133) (for example, a field effect transistor (FET), a transistor, or an insulated gate bipolar transistor (IGBT)) configured to control power supply to the brush device 2000; and a load detection sensor 1134 (for example, a shunt resistor, a shunt resistor and an amplification circuit (operational amplifier (OP-AMP)), a current detection sensor, or a magnetic field detection sensor (non-contact method)) configured to detect a load of the brush device 2000. Hereinafter, for ease of description, for example, a FET may be described as an embodiment of the PWM control switch device 1133, and a shunt resistor may be described as an embodiment of the load detection sensor 1134.

[0072] In an embodiment of the present disclosure, the first processor 1131 may obtain data related to the state of the adsorption motor 1110 (hereinafter, also referred to as state data). The first processor 1131 may send the state data of the adsorption motor 1110 to the main processor 1800. The first processor 1131 may send a signal (hereinafter, referred to as a first signal) to the brush device 2000 through the signal line by controlling (e.g., turning on or off) the operation of the first switch device 1132 connected to the signal line. The first switch device 1132 is a device that changes the state of the signal line to low.

The first processor 1131 may send the data indicating the current state of the brush device 2000 or the data indicating the type of the brush device 2000 included in the second signal to the main processor 1800.

[0074] In an embodiment of the present disclosure, the dust collection container 1200 can contain foreign matter sucked up from the surface to be cleaned. The dust collection container 1200 can be configured to filter out dust or dirt in the air introduced by the brush device 2000, and collect the filtered dust or dirt. The dust collection container 1200 can be configured to be attached to the main body 1000 or detached from the main body 1000.

[0075] In an embodiment of the present disclosure, the dust collecting container 1200 can collect and store foreign matter included in the air discharged to the outside. The dust collecting container 1200 can collect foreign matter by a cyclonic method of separating foreign matter by centrifugal force. The air from which foreign matter has been removed by the cyclonic method can be discharged to the outside of the main body 1000. In an embodiment, for example, a multi-cyclone separator can be arranged inside the dust collecting container 1200. The dust collecting container 1200 can be configured so that foreign matter is collected below the multi-cyclone separator.

[0076] In an embodiment of the present disclosure, the dust collection container 1200 may include a dust collection container door (also referred to as a cover 10 of the dust collection container 1200), which is configured so that the dust collection container 1200 is opened when connected to the station 200. The dust collection container 1200 may include: a first dust collection portion, in which relatively large foreign matter is mainly collected; and a second dust collection portion, in which relatively small foreign matter collected by the multi-stage cyclone separator is collected. Both the first dust collection portion and the second dust collection portion may be configured to open outward when the dust collection container door is opened.

[0077] In an embodiment of the present disclosure, the filter portion 1300 may filter out fine particulate matter that is not filtered out by the dust collection container 1200. The filter portion 1300 may include a discharge port for discharging air passing through the filter to the outside of the cordless vacuum cleaner 100. In an embodiment, the filter portion 1300 may include, for example, a motor filter or a HEPA filter.

[0078] In an embodiment of the present disclosure, the pressure sensor 1400 can measure the pressure inside the flow path (hereinafter, also referred to as flow path pressure). The pressure sensor 1400 disposed at the adsorption end (e.g., adsorption conduit 40) can measure the flow velocity change at the corresponding position by measuring the static pressure. The pressure sensor 1400 can be an absolute pressure sensor or a relative pressure sensor.

[0079] In an embodiment of the present disclosure, when the pressure sensor 1400 is an absolute pressure sensor, the main processor 1800 may sense a first pressure value before the adsorption motor 1110 operates through the pressure sensor 1400. The main processor 1800 may sense a second pressure value after the adsorption motor 1110 operates at the target RPM. The main processor 1800 may obtain the difference between the first pressure value and the second pressure value as the pressure value inside the flow path. The first pressure value may be a pressure value according to internal / external influences such as weather, altitude, the state of the cordless vacuum cleaner 100, and the amount of dust introduced. The second pressure value may be a pressure value according to the driving of the adsorption motor 1110 and according to internal / external influences such as altitude, the state of the cordless vacuum cleaner 100, and the amount of dust introduced. The difference between the first pressure value and the second pressure value may be a pressure value according to the driving of the adsorption motor 1110. Therefore, when the difference between the first pressure value and the second pressure value is used as the pressure value inside the flow path, internal / external influences other than the adsorption motor 1110 may be reduced. In an embodiment, the flow path pressure measured by the pressure sensor 1400 can be used, for example, to identify the current use environment state of the brush device 2000 (e.g., the state of the surface to be cleaned (hard floor, carpet, mat or corner) or the state of being lifted from the surface to be cleaned). In an embodiment, the flow path pressure measured by the pressure sensor 1400 can be used, for example, to measure the adsorption power that changes according to the degree of contamination or dust collection of the dust collection container 1200.

[0080] In an embodiment of the present disclosure, the pressure sensor 1400 may be disposed at the adsorption end (e.g., adsorption duct 40). The adsorption duct 40 may be a structure in which the dust collection container 1200 and the extension tube 3000 are connected to each other or the dust collection container 1200 and the brush device 2000 are connected to each other so that the fluid including foreign matter can move to the dust collection container 1200. In an embodiment, for example, in consideration of the contamination of dirt / dust, the pressure sensor 1400 may be disposed at the end of the straight portion of the adsorption duct 40 (or the inflection point of the straight portion and the curved portion). In an embodiment, the pressure sensor 1400 may be disposed, for example, at the center of the straight portion of the adsorption duct 40. When the pressure sensor 1400 is disposed at the adsorption duct 40, the pressure sensor 1400 is disposed at the front end of the adsorption motor 1110 that generates adsorption power, and therefore, the pressure sensor 1400 may be implemented as a negative pressure sensor.

[0081] In the present disclosure, the pressure sensor 1400 is disposed at the adsorption duct 40, but the embodiments of the present disclosure are not limited thereto. The pressure sensor 1400 may be disposed at the discharge end (e.g., inside the motor assembly 1100). When the pressure sensor 1400 is disposed at the discharge end, the pressure sensor 1400 is disposed at the rear end of the adsorption motor 1110, and thus, the pressure sensor 1400 may be implemented as a positive pressure sensor. In addition, a plurality of pressure sensors 1400 may be disposed in the cordless vacuum cleaner 100.

The first battery 1510 may be a large-capacity battery that may improve the adsorption performance of the main body 1000 by increasing the output power. In an embodiment, the first battery 1510 may output a power of about 730 watts (W). In the present disclosure, a large-capacity battery may also be referred to as a performance battery, for example.

[0084] In an embodiment of the present disclosure, the second battery 1520 may have a second ID. The second battery 1520 may have a second capacity. The second capacity may be less than the first capacity. In an embodiment, the second capacity may be, for example, a battery capacity for operating the main body 1000 for about 60 minutes in general mode. The second battery 1520 may have a second weight. The second weight may be less than the first weight. In an embodiment, the second weight may be about 500g.

In addition, the cordless vacuum cleaner 100 in the embodiment of the present disclosure can operate the adsorption motor 1110 according to the state of the at least one battery 1500, thereby improving the stability of the at least one battery 1500, the life of the at least one battery 1500, and the use time of the at least one battery 1500.

[0171] In the following, reference will be made to Fig.14 The power consumption of the suction motor 1110 according to the operation mode of the cordless vacuum cleaner 100 is described.

[0172] Fig.14 is a table showing an embodiment of a result of controlling the output of the adsorption motor 1110 according to an operation mode of the cordless vacuum cleaner 100 according to the present disclosure.

[0173] In an embodiment of the present disclosure, at least one processor 1800 of the main body 1000 of the cordless vacuum cleaner 100 may set the power consumption of the adsorption motor 1110 for each operation mode of the cordless vacuum cleaner 100. In an embodiment, the at least one processor 1800 may set the power consumption of the adsorption motor 1110 to about 580W in the jet mode, for example. In an embodiment, the at least one processor 1800 may set the power consumption of the adsorption motor 1110 to about 320W in the super power mode, for example. In an embodiment, the at least one processor 1800 may set the power consumption of the adsorption motor 1110 to about 113W in the power mode, for example.

[0174] In an embodiment of the present disclosure, at least one processor 1800 may increase the rotation RPM of the impeller of the adsorption motor 1110 by increasing the power consumption of the adsorption motor 1110. When the rotation RPM of the adsorption motor 1110 increases, the vacuum degree and flow rate inside the cordless vacuum cleaner 100 may increase, and thus the dust adsorption power of the cordless vacuum cleaner 100 may increase. In an embodiment, the adsorption power in the jet mode may be about 220W. In an embodiment, the adsorption power in the super power mode may be about 125W. In an embodiment, the adsorption power in the power mode may be about 40W. In an embodiment, the adsorption power in the general mode may be about 18W.

[0176] The usage time of the cordless vacuum cleaner 100 in the embodiment of the present disclosure may be shortened as the power consumption and the suction power increase. The at least one processor 1800 may control the power output from the at least one battery 1500 according to the operation mode of the cordless vacuum cleaner 100 .

[0177] In the following, reference will be made to Fig.15Power consumption according to the type of at least one battery 1500 and a normal mode or an overload mode of the at least one battery 1500 is described.

[0178] Fig.15 is a table showing an embodiment of a result of controlling the output of the adsorption motor 1110 according to an operation mode of the cordless vacuum cleaner 100 according to the present disclosure.

[0179] In an embodiment of the present disclosure, at least one processor 1800 of the main body 1000 of the cordless vacuum cleaner 100 may identify the type of at least one battery 1500 and an abnormality of at least one battery 1500. The at least one processor 1800 may control the maximum output mode based on the type of at least one battery 1500. In an embodiment, for example, in the spray mode of the light-weight type battery, compared with the performance type battery, the at least one processor 1800 may set the output of the adsorption motor 1110 to be low.

[0180] In an embodiment of the present disclosure, when the state of at least one battery 1500 is abnormal, in the abnormal mode, at least one processor 1800 may operate in the overload mode or the protection mode. In the overload mode, at least one processor 1800 may reduce the output of the adsorption motor 1110 in at least one operation mode including the maximum output mode. In an embodiment, for example, compared to the normal mode, at least one processor 1800 may reduce the output of the adsorption motor 1110 in the spray mode and the overpower mode to protect at least one battery 1500 in the overload mode. In the protection mode, at least one processor 1800 may stop the output of the adsorption motor 1110 in at least one operation mode including the maximum output mode. In an embodiment, for example, compared to the normal mode, at least one processor 1800 may stop the output of the adsorption motor 1110 in the spray mode and the overpower mode to protect at least one battery 1500 in the overload mode.

[0181] In the following, reference will be made to Fig.16 A full charge voltage and a final discharge voltage of at least one battery 1500 according to an operation mode are described.

[0182] Fig.16 is a table showing an embodiment of a result of controlling at least one of a full charge voltage or a final discharge voltage of the battery 1500 according to an operation mode of the cordless vacuum cleaner 100 according to the present disclosure.

[0183] In an embodiment of the present disclosure, at least one processor 1800 of the main body 1000 of the cordless vacuum cleaner 100 may identify an operation mode of the cordless vacuum cleaner 100. In an embodiment, the at least one processor 1800 may, for example, identify which mode of the jet mode, the super power mode, the power mode, and the general mode the operation mode of the cordless vacuum cleaner 100 corresponds to. The at least one processor 1800 may identify the power consumed by the adsorption motor 1110 in the current operation mode of the cordless vacuum cleaner 100. The at least one processor 1800 may identify the usage time in the current operation mode of the cordless vacuum cleaner 100.

[0184] In an embodiment of the present disclosure, at least one processor 1800 may control at least one of a full charge voltage or a final discharge voltage of at least one battery 1500 based on an operation mode of the cordless vacuum cleaner 100. The full charge voltage may be a voltage when the at least one battery 1500 is fully charged. The final discharge voltage may be a voltage at a cut-off time when the at least one battery 1500 stops outputting power. The at least one processor 1800 may set the full charge voltage and the final discharge voltage of the at least one battery 1500 differently to improve the life and usage time of the at least one battery 1500.

[0185] In an embodiment of the present disclosure, at least one processor 1800 may reduce the full charge voltage and increase the final discharge voltage in the maximum output mode of the adsorption motor 1110. In an embodiment, for example, when the cordless vacuum cleaner 100 is in the spray mode, the at least one processor 1800 may control the full charge voltage of the at least one battery 1500 to be about 4.10V and the final discharge voltage to be about 2.8V. In the spray mode, which is the maximum output mode of the adsorption motor 1110, the power supplied by the at least one battery 1500 to the adsorption motor 1110 may be maximum to maximize the output power of the adsorption motor 1110. The maximum output mode of the adsorption motor 1110 may directly affect the life of the at least one battery 1500. Therefore, when the cordless vacuum cleaner 100 is in the spray mode, the at least one processor 1800 may control the full charge voltage and the final discharge voltage of the at least one battery 1500 in consideration of the improvement of the life of the at least one battery 1500.

[0186] In an embodiment of the present disclosure, at least one processor 1800 may increase the full charge voltage and reduce the final discharge voltage in an operation mode other than the maximum output mode of the adsorption motor 1110. When the output of the adsorption motor 1110 is reduced, the at least one processor 1800 may increase the full charge voltage and reduce the final discharge voltage. In an embodiment, for example, when the cordless vacuum cleaner 100 is in the super power mode, the at least one processor 1800 may control the full charge voltage of the at least one battery 1500 to about 4.16V and the final discharge voltage to about 2.6V. In an embodiment, for example, when the cordless vacuum cleaner 100 is in the power mode, the at least one processor 1800 may control the full charge voltage of the at least one battery 1500 to about 4.2V and the final discharge voltage to about 2.6V. In an embodiment, for example, when the cordless vacuum cleaner 100 is in the general mode, the at least one processor 1800 may control the full charge voltage of the at least one battery 1500 to about 4.2V and the final discharge voltage to about 2.5V. The cordless vacuum cleaner 100 can reduce the influence of the full charge voltage and the final discharge voltage on the life of the at least one battery 1500 in the operation mode other than the maximum output mode. Therefore, the at least one processor 1800 can increase the full charge voltage and reduce the final discharge voltage in the operation mode other than the maximum output mode to increase the usage time of the cordless vacuum cleaner 100.

[0187] The cordless vacuum cleaner 100 in the embodiment of the present disclosure can control at least one of the full charge voltage or the final discharge voltage of at least one battery 1500 according to whether the operation mode is the maximum output mode or other modes. At least one of the full charge voltage or the final discharge voltage of at least one battery 1500 can be controlled differently in consideration of both the life of the at least one battery 1500 and the usage time of the cordless vacuum cleaner 100.

[0188] In the following, reference will be made to Fig.17 A method of controlling power consumption according to the temperature of at least one battery 1500 is described.

[0189] Fig.17 is a table showing an embodiment of a result of controlling the output of the adsorption motor 1110 according to temperature information of the battery 1500 of the cordless vacuum cleaner 100 according to the present disclosure.

[0190] In an embodiment of the present disclosure, the main body 1000 of the cordless vacuum cleaner 100 may further include a temperature sensor 1547. The temperature sensor 1547 may obtain temperature information of the at least one battery 1500. In an embodiment, the temperature sensor 1547 may be disposed adjacent to the at least one battery 1500, for example.

[0191] In an embodiment of the present disclosure, at least one processor 1800 of the main body 1000 of the cordless vacuum cleaner 100 may control the temperature sensor 1547 to obtain temperature information of at least one battery 1500. At least one processor 1800 may control power consumption of the adsorption motor 1110 according to the heating level of at least one battery 1500.

[0192] In an embodiment of the present disclosure, when the temperature information of at least one battery 1500 is equal to or greater than a first threshold temperature, at least one processor 1800 may gradually reduce the output of the adsorption motor 1110. In an embodiment, for example, when the temperature of at least one battery 1500 is equal to or greater than about 60 degrees Celsius (°C) and less than about 65°C, power consumption may be reduced by about 10%. In an embodiment, for example, when the temperature of at least one battery 1500 is equal to or greater than about 65°C and less than about 70°C, power consumption may be reduced by about 30%. At the first threshold temperature or higher, the at least one processor 1800 may gradually reduce the output of the adsorption motor 1110 in consideration of the life of the at least one battery 1500 and the usage time of the at least one battery 1500.

[0193] In an embodiment of the present disclosure, when the temperature information of at least one battery 1500 is equal to or greater than a second threshold temperature greater than the first threshold temperature, the at least one processor 1800 may stop the operation of the adsorption motor 1110. In an embodiment, when the temperature of at least one battery 1500 is equal to or greater than about 70° C., the operation of the adsorption motor 1110 may be stopped. Excessive heating of at least one battery 1500 may, for example, directly affect the life of at least one battery 1500. Therefore, at the second threshold temperature or higher, the at least one processor 1800 may immediately stop the operation of the adsorption motor 1110, first considering the safety and life of the at least one battery 1500.

[0194] In the following, reference will be made to Fig.18 A method of controlling a full charge voltage and a final discharge voltage of at least one battery 1500 according to a use cycle of the at least one battery 1500 is described.

[0195] Fig.18 is a table showing an embodiment of a result of controlling at least one of a full charge voltage or a final discharge voltage of the battery 1500 according to a use cycle of the cordless vacuum cleaner 100 according to the present disclosure.

[0196] In an embodiment of the present disclosure, at least one processor 1800 of the main body 1000 of the cordless vacuum cleaner 100 may obtain a use cycle of at least one battery 1500. The use cycle may be the number of times that at least one battery 1500 has reached a fully charged state and / or a fully discharged state according to charging, use, and discharging of the at least one battery 1500. In an embodiment, the at least one processor 1800 may obtain the use cycle of at least one battery 1500 by, for example, dividing the range of the use cycle into a range of 300 times or less, a range between 301 times and 600 times, a range between 601 times and 800 times, and a range of 801 times or more.

[0197] In an embodiment of the present disclosure, when the use cycle of at least one battery 1500 increases, at least one processor 1800 may reduce the full charge voltage of at least one battery 1500 and increase the final discharge voltage of at least one battery 1500. Considering the life of at least one battery 1500, when the use cycle increases, at least one processor 1800 may reduce the full charge voltage of at least one battery 1500 and increase the final discharge voltage of at least one battery 1500. In an embodiment, for example, when the use cycle is equal to or less than 300 times, at least one processor 1800 may control the full charge voltage of at least one battery 1500 to about 4.16V and the final discharge voltage of at least one battery 1500 to about 2.7V. In an embodiment, for example, when the use cycle is between 301 and 600 times, at least one processor 1800 may control the full charge voltage of at least one battery 1500 to about 4.10V and the final discharge voltage of at least one battery 1500 to about 2.8V. In an embodiment, for example, when the usage cycle is between 601 and 800 times, the at least one processor 1800 may control the full charge voltage of the at least one battery 1500 to about 4.05 V and the final discharge voltage of the at least one battery 1500 to about 2.89 V. In an embodiment, for example, when the usage cycle is equal to or greater than 801 times, the at least one processor 1800 may control the full charge voltage of the at least one battery 1500 to about 4.00 V and the final discharge voltage of the at least one battery 1500 to about 3.0 V. Therefore, the at least one processor 1800 may minimize or recover the shortening of the life of the at least one battery 1500 according to the increase in the usage cycle.

[0198] In an embodiment of the present disclosure, in consideration of a usage cycle when the cordless vacuum cleaner 100 is used in a maximum output mode, at least one processor 1800 may reduce a full charge voltage of at least one battery 1500 and increase a final discharge voltage of at least one battery 1500. When the cordless vacuum cleaner 100 is used in a maximum output mode, the life of at least one battery 1500 may be greatly affected. Therefore, at least one processor 1800 may control a full charge voltage and a final discharge voltage in consideration of only a usage cycle in a maximum output mode that greatly affects the life, so as to recover the shortened life of at least one battery 1500. In an embodiment, for example, at least one processor 1800 may reduce a full charge voltage of at least one battery 1500 and increase a final discharge voltage of at least one battery 1500 in consideration of only a usage cycle when the cordless vacuum cleaner 100 is used in a spray mode having the highest output among convenient situations in which the cordless vacuum cleaner 100 is used alone. At least one processor 1800 may not consider a usage cycle in an operation mode that has a relatively small impact on the life of at least one battery 1500. Therefore, the at least one processor 1800 can prevent the usage time of the at least one battery 1500 from being shortened unnecessarily.

[0199] The cordless vacuum cleaner 100 in the embodiment of the present disclosure may include a main body 1000 and a station 200. The main body 1000 in the embodiment of the present disclosure may include: an adsorption motor 1110 configured to rotate a fan to suck up dust; at least one battery 1500 to supply power to the adsorption motor 1110; and at least one processor 1800.

[0203] In an embodiment of the present disclosure, the body 1000 may further include a battery coupling portion 1550 coupled to the at least one battery 1500. The at least one processor 1800 in an embodiment of the present disclosure may identify the type of the at least one battery 1500 based on whether the terminal accommodating portion 1560 of the at least one battery 1500 contacts the identification terminal 1551 of the battery coupling portion 1550.

[0204] In an embodiment of the present disclosure, when at least one battery 1500 is a large-capacity battery, at least one processor 1800 may control the output of the adsorption motor 1110 to be a first output. When at least one battery 1500 is a small-capacity battery, at least one processor 1800 may control the output of the adsorption motor 1110 to be a second output lower than the first output.

[0205] In an embodiment of the present disclosure, when the at least one battery 1500 is in the normal mode, the at least one processor 1800 may control the output of the adsorption motor 1110 to the third output. When the at least one battery 1500 is in the overload mode, the at least one processor 1800 may control the output of the adsorption motor 1110 to the fourth output lower than the third output.

[0206] In an embodiment of the present disclosure, at least one processor 1800 may operate the adsorption motor 1110 in one of a first mode in which the output has a first intensity and a second mode in which the output has a second intensity lower than the first intensity.

[0207] In an embodiment of the present disclosure, the body 1000 may further include a temperature sensor 1547. The at least one processor 1800 may control the temperature sensor 1547 to obtain temperature information of the at least one battery 1500. When the temperature information is equal to or greater than a first threshold temperature and less than a second threshold temperature higher than the first threshold temperature, the at least one processor 1800 may gradually reduce the output of the adsorption motor 1110. When the temperature information is equal to or greater than a second threshold temperature higher than the first threshold temperature, the at least one processor 1800 may stop the adsorption motor 1110.
