Description

Vacuum cleaner equipped with turbidity correction function and method of operation thereof

[0001] The present invention relates to a vacuum cleaner equipped with a turbidity correction function and a method of operation thereof, and more specifically, to a vacuum cleaner equipped with a turbidity correction function that corrects the contamination level measured by a turbidity sensor based on a preset standard contamination level and a method of operation thereof.

[0002] The vacuum cleaner can clean dry by sucking up dust or using a brush, or wet by spraying steam onto the floor or supplying water to a rotating mop. Additionally, the water used for cleaning (wash water) is recovered through the vacuum cleaner's suction motor and suction pipe.

[0003] Additionally, after cleaning, the vacuum cleaner can perform cleaning of the rotary mop when mounted on its charging device (e.g., station). At this time, the rotary mop is cleaned by supplying steam or water from the station. The water used to clean the rotary mop (cleaning water) is then recovered through the vacuum cleaner's suction motor and suction pipe.

[0004] The vacuum cleaner controls cleaning intensity and performs rotary mop cleaning based on the contamination level of the cleaning water sucked in through the suction pipe. At this time, the vacuum cleaner uses a turbidity sensor placed in the suction pipe to measure the contamination level of the cleaning water; however, the measurement accuracy of the turbidity sensor varies depending on the surrounding environment. For example, in the case of a vacuum cleaner used for a long period, the measurement sensitivity of the turbidity sensor may change as the surrounding environment changes due to discoloration, ignition, etc. Consequently, in the case of conventional technology, the contamination level of the cleaning water may be measured inaccurately, and there was a problem in that the vacuum cleaner could not optimally perform cleaning intensity or rotary mop cleaning due to the inaccurate contamination measurement.

[0005] Meanwhile, self-cleaning technology for vacuum cleaner mop is generally performed in the form of wetting, washing, and drying. In this regard, conventional technology performed self-cleaning uniformly according to a pre-set procedure without considering the degree of contamination of the mop. Consequently, self-cleaning that does not consider the degree of contamination of the mop had problems such as excessive energy consumption relative to the level of contamination or insufficient cleaning of the mop.

[0006] The present invention was devised to solve the problems described above, and the objective of the present invention is to provide a vacuum cleaner equipped with a turbidity correction function capable of accurately measuring the contamination level of washing water by correcting the contamination level measured by a turbidity sensor based on a preset standard contamination level, and a method of operation thereof.

[0007] Another objective of the present invention is to provide a cleaner equipped with a turbidity correction function capable of calculating the contamination level of washing water and efficiently performing washing of a rotary mop based on the calculated contamination level of washing water, and a method of operating the same.

[0008] The objectives of the present invention are not limited to the problems mentioned above, and other objectives and advantages of the present invention not mentioned may be understood from the following description and will be more clearly understood by the embodiments of the present invention. Furthermore, it will be understood that the objectives and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims.

[0009] A vacuum cleaner equipped with a turbidity correction function according to the present invention for solving the problem described above is characterized by the technical feature of calculating the pollution level measured by a turbidity sensor by correcting it based on a preset standard pollution level.

[0010] Specifically, the contamination level of the washing water measured by the turbidity sensor is corrected based on a preset standard contamination level, which is the contamination level measured when the washing water is at its lowest contamination level, thereby reflecting changes in the surrounding environment of the turbidity sensor and enabling the calculation of the washing water contamination level.

[0011] For the above purpose, a vacuum cleaner having a turbidity correction function according to one embodiment of the present invention comprises: a turbidity sensor unit for measuring the contamination level of washing water sucked through a suction pipe; and a processor unit for calculating the contamination level of the washing water by correcting the contamination level of the measured washing water based on a preset standard contamination level.

[0012] Preferably, the above-mentioned standard contamination level is the contamination level of the washing water measured at the time of completion of the rotary mop washing of the vacuum cleaner.

[0013] Preferably, the preset standard contamination level is the lowest contamination level measured by the turbidity sensor unit during a preset time.

[0014] Preferably, the processor unit divides the contamination level of the washing water into a plurality of contamination level ranges based on the preset standard contamination level, sets a contamination level corresponding to each contamination level range, and then calculates a contamination level corresponding to the contamination level range corresponding to the measured contamination level of the washing water.

[0015] Preferably, the system further includes a rotary mop washing unit that performs washing on the rotary mop based on the contamination level of the calculated washing water.

[0016] Preferably, the rotary mop washing unit estimates the contamination level of the rotary mop based on the contamination level of the calculated washing water and the cleaning time, and performs washing on the rotary mop based on the estimated contamination level of the rotary mop.

[0017] Preferably, the rotary mop washing unit sets the washing intensity for the rotary mop higher as the estimated contamination level of the rotary mop increases.

[0018] Preferably, the rotary mop washing unit controls the amount of detergent and water introduced for washing the rotary mop according to the set washing intensity.

[0019] Preferably, the rotary mop washing unit controls the washing time and rinsing time for the rotary mop according to the set washing intensity.

[0020] Preferably, the system further includes a notification unit that provides a notification to the user when the contamination level of the calculated washing water is greater than or equal to a preset limit contamination level.

[0021] Meanwhile, a method of operation of a vacuum cleaner equipped with a turbidity correction function according to one embodiment of the present invention comprises: a step of measuring the contamination level of washing water sucked through a suction pipe; and a step of calculating the contamination level of the washing water by correcting the contamination level of the measured washing water based on a preset standard contamination level.

[0022] Preferably, the step of calculating the contamination level of the washing water includes a process of dividing the contamination level of the washing water into multiple sections based on the previously set standard contamination level, setting a contamination level corresponding to each contamination level section, and then calculating a contamination level corresponding to the contamination level section corresponding to the measured contamination level of the washing water.

[0023] Preferably, the method further includes the step of performing washing on the rotary mop based on the contamination level of the calculated washing water.

[0024] Preferably, the step of performing washing on the rotary mop comprises: a process of estimating the contamination level of the rotary mop based on the contamination level of the calculated washing water and the cleaning time; and a process of performing washing on the rotary mop based on the estimated contamination level of the rotary mop.

[0025] Preferably, the method further includes the step of providing a notification to the user when the contamination level of the calculated washing water is greater than or equal to a preset limit contamination level.

[0026] According to the present invention, the contamination level of the washing water measured based on a standard contamination level is corrected to have the effect of accurately measuring the contamination level of the washing water.

[0027] Furthermore, according to the present invention, since the standard contamination level is set in response to changes in the external environment (e.g., water tank, suction pipe), it has the effect of accurately measuring the contamination level of the washing water even during long-term use.

[0028] In addition, according to the present invention, if the measured contamination level of the washing water exceeds a preset limit contamination level, it provides a notification to the user, thereby inducing the user to check the status of the vacuum cleaner.

[0029] Furthermore, according to the present invention, by performing cleaning of the rotating mop of a vacuum cleaner based on the contamination level of the rotating mop estimated based on the contamination level of the cleaning water, the cleaning of the rotating mop is performed efficiently, thereby providing the effect of saving energy.

[0033] FIG. 4 is a flowchart of a cleaning method for a vacuum cleaner equipped with a turbidity correction function according to one embodiment of the present invention.

[0034] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. However, in describing the present invention, descriptions of already known functions or configurations will be omitted in order to clarify the gist of the present invention.

[0035] Hereinafter, a vacuum cleaner equipped with a turbidity correction function according to the present invention and a method of operation thereof will be described in detail with reference to FIGS. 1 to 4.

[0036] FIG. 1 is a configuration diagram of a vacuum cleaner equipped with a turbidity correction function according to one embodiment of the present invention, and FIG. 2 is a flowchart of an operation method of a vacuum cleaner equipped with a turbidity correction function according to one embodiment of the present invention.

[0037] Referring to FIG. 1, a vacuum cleaner (100) equipped with a turbidity correction function according to one embodiment of the present invention includes a turbidity sensor unit (110), a processor unit (120), a rotary mop cleaning unit (130), a notification unit (140), etc.

[0038] The turbidity sensor unit (110) measures the contamination level of the washing water used to wash the rotating mop of the vacuum cleaner (100) (see step S210 of FIG. 2).

[0039] For example, the turbidity sensor unit (110) may be formed of a plurality of sensors and may consist of a light-emitting unit that emits light of a specific wavelength range and a light-receiving unit that receives light emitted from the light-emitting unit. In this case, the light-emitting unit may be implemented as an LED that emits light of a specific wavelength range, and the light-receiving unit may receive light irradiated from the light-emitting unit.

[0040] When light is irradiated from the light-emitting unit toward the light-receiving unit, the irradiated light passes through the washing water and is input into the light-receiving unit. When the light-receiving unit receives the light that has passed through the washing water, a voltage is applied to an internal resistor, and the turbidity sensor unit (110) measures the degree of contamination of the washing water based on the voltage applied to the light-receiving unit.

[0041] For example, the turbidity sensor unit (110) can measure the contamination level of the washing water by expressing the voltage applied to the resistor of the light receiving unit in 12 bits. Specifically, when the voltage applied to the resistor is expressed in 12 bits, the turbidity sensor unit (110) can express the voltage applied to the resistor of the light receiving unit as a voltage level of 4096 by corresponding the minimum value (min) and maximum value (max) of the voltage applied to the light receiving unit to 0 and 4095, respectively. Accordingly, it can be seen that the closer the voltage level is to 0, the higher the contamination level of the washing water, and the closer the voltage level is to 4095, the lower the contamination level of the washing water.

[0042] However, the turbidity sensor unit (110) may have a deviation in measurement accuracy depending on the surrounding environment. For example, the aging of the light-emitting unit and / or light-receiving unit, contamination, discoloration, ignition of the surrounding environment of the turbidity sensor, etc., may cause the contamination measurement sensitivity of the turbidity sensor unit (110) to change, resulting in an error in the contamination measurement. Accordingly, the vacuum cleaner (100) according to the present invention corrects the contamination measured based on a preset standard contamination level to accurately calculate the contamination level of the washing water.

[0043] The processor unit (120) calculates the contamination level of the washing water by correcting the contamination level measured by the turbidity sensor unit (110) based on a preset standard contamination level (see step S220 of FIG. 2).

[0044] In this regard, FIG. 3 is a detailed flowchart for step S220 of FIG. 2.

[0045] Referring to FIG. 3, the processor unit (120) loads a preset standard contamination level (refer to step S221 of FIG. 3).

[0046] Here, the preset standard contamination level is the contamination level measured when the washing water is at its cleanest. The processor unit (120) can measure the contamination level of the washing water by setting the contamination level measured when the contamination level of the washing water is at its lowest as the standard contamination level, thereby reflecting changes in the environment around the turbidity sensor.

[0047] In this case, the pre-set standard contamination level can be implemented as the contamination level of the washing water measured at the end of the rotary mop washing of the vacuum cleaner (100).

[0048] The point at which the rotary mop cleaning ends is when the contamination level of the cleaning water is at its lowest, and the cleaner (100) can set the contamination level of the cleaning water measured at each point at which the rotary mop cleaning ends as the reference contamination level.

[0049] In addition, the preset standard pollution level can be implemented as the lowest pollution level measured by the turbidity sensor unit (110) during a preset time.

[0050] For example, the preset time can be implemented as the lowest contamination level among the contamination levels measured during the 48 hours prior to the end of the rotational mop wash.

[0051] In this way, the processor unit (120) can set the lowest contamination level among the contamination levels measured for a certain period of time in an environment with the lowest contamination level of the washing water as the reference contamination level, and correct the contamination level of the washing water measured based on the set reference contamination level to accurately calculate the contamination level of the washing water.

[0052] For reference, the processor unit (120) can manage data regarding the standard contamination level through a permanent storage device (e.g., EEPROM), and thereby maintain the standard contamination level even when the power of the vacuum cleaner (100) is turned off.

[0053] The processor unit (120) divides the contamination level of the washing water into multiple sections based on a preset standard contamination level (see step S222 of FIG. 3).

[0054] Preferably, the processor unit (120) divides the contamination level of the washing water into multiple sections based on a voltage level corresponding to a preset standard contamination level.

[0055] For example, assuming that the voltage level corresponding to the preset standard contamination level is 4000 and the contamination level is divided into four sections, the processor unit (120) can divide it into four sections such as 4000~3001, 3000~2001, 2000~1001, and 1000~0.

[0056] Meanwhile, for example, assuming that the voltage level corresponding to the preset standard contamination level is 3500 and the contamination level is divided into four sections, the processor unit (120) can divide the contamination level into four sections such as 3500~2626, 2625~1751, 1750~876, and 875~0.

[0057] Then, the processor unit (120) sets a contamination level corresponding to each contamination level range (see step S223 of FIG. 3).

[0058] For example, assuming that the voltage level corresponding to the preset standard contamination level is 4000 and the contamination level is divided into four sections, the processor unit (120) can set the contamination level to 1 for the section from 4000 to 3001, set the contamination level to 2 for the section from 3000 to 2001, set the contamination level to 3 for the section from 2000 to 1001, and set the contamination level to 4 for the section from 1000 to 0.

[0059] Meanwhile, for example, assuming that the voltage level corresponding to the previously set standard contamination level is 3500 and the contamination level is divided into four sections, the processor unit (120) can set the contamination level to 1 for the section from 3500 to 2626, the contamination level to 2 for the section from 2625 to 1751, the contamination level to 3 for the section from 1750 to 876, and the contamination level to 4 for the section from 875 to 0.

[0060] Then, the processor unit (120) calculates a contamination level corresponding to a contamination level range corresponding to the contamination level of the washing water measured by the turbidity sensor unit (110) (see step S224 of FIG. 3).

[0061] For example, assuming that the voltage level corresponding to the preset standard pollution level is 4000 and the pollution level is divided into 4 sections, and the voltage level corresponding to the pollution level measured by the turbidity sensor unit (110) is 1800, the processor unit (120) calculates the pollution level corresponding to the measured pollution level as 3.

[0062] Meanwhile, for example, if the voltage level corresponding to the preset standard pollution level is 3500 and the pollution level is divided into four sections, and the voltage level corresponding to the pollution level measured by the turbidity sensor unit (110) is 1800, the processor unit (120) calculates the pollution level corresponding to the measured pollution level as 2.

[0063] Then, the processor unit (120) determines whether the contamination level of the calculated washing water is greater than or equal to a preset limit contamination level (see step S230 of FIG. 2).

[0064] For example, assuming that the set limit of contamination is 3 and the calculated contamination level of the washing water is 4, the processor unit (120) determines that the calculated contamination level of the washing water is greater than or equal to the set limit of contamination.

[0065] Additionally, the processor unit (120) can determine whether the contamination level is greater than a preset limit based on the voltage level corresponding to the contamination level of the washing water measured by the turbidity sensor unit (110).

[0066] For example, assuming that the voltage level corresponding to the contamination level of the washing water measured by the turbidity sensor unit (110) is 3000 and the voltage level corresponding to the preset limit contamination level is 500, the processor unit (120) determines that the contamination level of the washing water measured is lower than the limit contamination level (for reference, the voltage level and the contamination level are opposite to each other).

[0067] Meanwhile, for example, if the voltage level corresponding to the contamination level of the washing water measured by the turbidity sensor unit (110) is 250 and the voltage level corresponding to the preset limit contamination level is 500, the processor unit (120) determines that the measured contamination level of the washing water is higher than the limit contamination level.

[0068] If it is determined that the contamination level calculated by the processor unit (120) is less than a preset limit contamination level, the rotary mop washing unit (130) performs rotary mop washing based on the calculated contamination level (see step S240 of FIG. 2).

[0069] The rotary mop washing unit (130) can perform rotary mop washing by setting the rotary mop washing intensity higher as the contamination level of the produced washing water increases.

[0070] For example, the rotary mop washing unit (130) can classify the rotary mop washing intensity into “strong,” “medium,” and “weak,” and set the rotary mop washing intensity based on the calculated contamination level.

[0071] And, the rotary mop washing unit (130) can control the amount of detergent and water supplied to the rotary mop washing according to the set rotary mop washing intensity.

[0072] For example, the rotary mop washing unit (130) controls the amount of detergent and water to be supplied relatively more than the amount of detergent and water supplied when the rotary mop washing intensity is "weak", if the set rotary mop washing intensity is "strong".

[0073] Additionally, the rotary mop washing unit (130) can control the rotary mop washing time and rinsing time according to the set rotary mop washing intensity.

[0074] For example, the rotary mop washing unit (130) controls the time so that if the set rotary mop washing intensity is "strong," the washing and rinsing are performed for a relatively longer time than the washing and rinsing time set when the rotary mop washing intensity is "weak."

[0075] Meanwhile, if the calculated contamination level is greater than or equal to a preset limit contamination level, the processor unit (120) notifies the notification unit (140), and the notification unit (140) provides a notification to the user (see step S250 of FIG. 2).

[0076] For example, if the calculated contamination level is greater than the limit contamination level, the processor unit (120) determines that the contamination is severe because foreign matter has not been removed from the suction pipe, and the notification unit (140) can notify the user of this so that the user can check the condition of the vacuum cleaner (100).

[0077]

[0078] Hereinafter, with reference to FIG. 4, a cleaning method for a vacuum cleaner equipped with a turbidity correction function according to one embodiment of the present invention will be described in detail.

[0079] FIG. 4 is a flowchart of a cleaning method for a vacuum cleaner equipped with a turbidity correction function according to one embodiment of the present invention.

[0080] As described above, a vacuum cleaner (100) equipped with a turbidity correction function according to one embodiment of the present invention determines whether the contamination level of the washing water calculated by the processor unit (120) is greater than or equal to a preset limit contamination level (see step S230 of FIG. 2), estimates the contamination level of the rotating mop, and performs washing of the rotating mop based on the estimated contamination level of the rotating mop.

[0081] Referring to FIG. 4, the processor unit (120) measures the cleaning time of the vacuum cleaner (100) (refer to step S410 of FIG. 4).

[0082] For reference, if the level of contamination in the area where the vacuum cleaner (100) performs cleaning is high, the cleaning time is longer, and if the level of contamination in the cleaning area is low, the cleaning time is shorter.

[0083] Then, the processor unit (120) estimates the contamination level of the rotary mop based on the calculated contamination level and the measured cleaning time (see step S420 of FIG. 4).

[0084] The processor unit (120) can estimate the contamination level of the rotary mop as one of "high," "medium," or "low" based on the calculated contamination level and the measured cleaning time.

[0085] For example, if the time taken to perform cleaning is 45 minutes or more and the calculated contamination level is high (e.g., contamination level 4), the contamination level of the rotating mop can be estimated as "high." On the other hand, if the time taken to perform cleaning is less than 20 minutes and the calculated contamination level is low (e.g., contamination level 1), the contamination level of the rotating mop can be estimated as "low."

[0086] Then, the rotary mop washing unit (130) performs washing on the rotary mop based on the estimated contamination level of the rotary mop (see step S430 of FIG. 4).

[0087] Preferably, the rotary mop washing unit (130) performs rotary mop washing by setting the rotary mop washing intensity higher as the estimated contamination level of the rotary mop increases.

[0088] For example, the rotary mop washing unit (130) can set the washing intensity to "strong" when the contamination level of the rotary mop is "high," set the washing intensity to "medium" when the contamination level of the rotary mop is "medium," and set the washing intensity to "weak" when the estimated contamination level of the rotary mop is "low."

[0089] Additionally, the rotary mop washing unit (130) controls the amount of detergent and water to be added to the rotary mop washing based on the set washing intensity, and controls the time for performing rotary mop washing and rinsing.

[0090] For example, the rotary mop cleaning unit (130) can control the vacuum cleaner (100) to supply relatively more detergent and water than the cleaning strength "weak" when the cleaning strength is set to "strong" when the rotary mop cleaning is performed.

[0091] The rotary mop washing unit (130) can control the cleaner (100) to perform rotary mop washing and rinsing for a longer period as the washing intensity increases.

[0092] For example, assuming the washing intensity is set to "strong," the washing unit (130) can control the washing time and rinsing time for the washing mop to be at least 15 minutes each, assuming the washing intensity is set to "medium," it can control the washing time and rinsing time for the washing mop to be at least 10 minutes and less than 15 minutes each, and assuming the washing intensity is set to "low," it can control the washing time and rinsing time for the washing mop to be at least 5 minutes and less than 10 minutes each.

[0093] Accordingly, the cleaner (100) can efficiently perform cleaning of the rotary mop by controlling the cleaning performance according to the degree of contamination of the rotary mop.
