In the drawings, like reference numerals are used throughout the drawings.

In addition, in the entire specification, when a part is referred to as being 'connected' to another part, it may be referred to as 'indirectly connected' not only with 'directly connected' .

1 is a block diagram showing functions of a power saving control apparatus according to an embodiment of the present invention.

1, a power saving control apparatus 100 according to an exemplary embodiment of the present invention may include a usage pattern generation unit 10 and a power source control unit 20, and may further include a human body detection sensor 30, (40).

Hereinafter, a power saving control apparatus 100 according to an embodiment of the present invention will be described with reference to FIG.

The power saving control device 100 may be located between the device 200 and the power source 300 to electrically connect the device 200 and the power source 300 as shown in FIG. Accordingly, the power saving control device 100 can adjust the electrical connection between the power source 300 and the device 200, and can adjust the amount of power supplied to the device 200 by the power source 300.

Specifically, the power saving control device 100 may adjust an amount of power supplied to the device 200 in consideration of a usage pattern of the device 200 by the user. That is, the device 200 is supplied with the operating power for operating the device 200 at a time when the device 200 is mainly used, and when the device 200 is not used mainly, The power consumed by the device 200 can be minimized.

In addition, the human body detection sensor 30 and the illuminance sensor 40 may be further used to compensate the power amount control using the usage pattern. That is, if the human body detection sensor 30 does not detect the human body even though the device 200 is used in the time zone in which the device 200 is used, the device 200 may not supply the device with the operating power, It is possible to supply the operation power to the device 200 when the human body detection sensor 30 detects the human body. In addition, if the illuminance sensor suddenly recognizes the illuminance at night and illuminance over a predetermined value is suddenly inputted, operation power is supplied to the apparatus 200 regardless of the usage pattern, Adjustment can be supplemented.

The device 200 collectively refers to mechanical and electrical devices having a specific purpose, and includes all household appliances such as a water purifier, a bidet, a dehumidifier, an air purifier, a refrigerator, and an air conditioner.

The device 200 can receive input from a user, and the operation can be controlled according to the input. Specifically, the device 200 may be in an operation standby state, and may perform an operation requested by a user at the request of the user. Here, the apparatus 200 may consume power even during the standby state, and more power than the amount of power consumed by the user may be consumed in the standby state.

For example, in the case of a water purifier, the water stored in the hot water tank can be continuously heated to provide the user with hot water. In this case, even though the user does not use the hot water, Power can be consumed.

Accordingly, in order to reduce the amount of power consumed in the operation standby state, the usage pattern of the apparatus 200 may be grasped and the amount of power supplied to the apparatus 200 may be adjusted according to the usage pattern. Particularly, in the case of the apparatus 200 in which the pattern of use is constantly formed according to a life pattern of a user such as a water purifier or a bidet, the power saving control apparatus 100 is preferably used. Also, it is more effective to apply the power saving control device 100 to the device 200, which has a longer waiting time for operation than the actual used time and consumes a large amount of power during the operation standby time.

Here, in order to obtain the usage pattern of the apparatus 200, it is necessary to detect the operation of the apparatus 200, and the operation of the apparatus 200 can be detected by various methods. Specifically, when a user applies an input for controlling the operation of the apparatus 200 to the apparatus 200, the apparatus 200 may be controlled based on a user's input or a control signal corresponding to the input. It is possible to detect an operation. Alternatively, the operation of the apparatus 200 may be sensed based on whether the apparatus 200 is actually operated or a control signal for the operation is input by an input of the user.

The power source 300 may be any power source capable of supplying power to the device 200, and may be generally a commercial AC power source or a battery. In addition, a DC or AC generator may be used as the power source 300.

1, the power saving control device 100 includes a usage pattern generation unit 10 for generating the usage pattern, and a power control unit 20 for controlling the amount of power supplied to the device 200 according to the usage pattern. (20).

The usage pattern generation unit 10 generates a usage pattern by sensing the operation of the device 200. The usage pattern generation unit 10 accumulates the operation time during which the device 200 operates during a reference period, .

Here, the operation time is a time between a time when the device 200 starts operation and a time when the device 200 ends the operation, and the reference time is a time unit for recording the operation time. That is, a section in which the apparatus 200 operates is recorded in a given reference time. Thereafter, the usage pattern can be obtained by repeatedly recording the recording between the above-mentioned openings during the reference period.

For example, if 24 hours is a reference time, the operation time of the device 200 during the 24 hours is recorded. Thereafter, when the operation time of the device 200 is accumulated for a week on the basis of the 24 hours, a usage pattern for a week of the device 200 can be obtained.

Generally, the operation time of the device 200 is measured at a reference time of 24 hours, but a usage pattern may be obtained at a reference time of 6 hours, 12 hours, 48 hours, or the like. In addition, the reference period can be selected in various ways, such as three days, one month, and so on.

In addition, after the reference period is set to 5 days and 2 days, it is possible to generate weekday usage pattern and weekend use pattern separately by separating weekday and weekend, and power saving control is performed in a separate usage pattern according to weekday and weekend It is also possible to do. Considering the living patterns of modern people living at work, there may be differences in life patterns between weekdays and weekends. Particularly, in household appliances such as water purifiers, bidets, and refrigerators in which the usage pattern is determined according to the user's living pattern, Similarly, it may be desirable to vary the power saving control operation according to usage pattern of weekday and weekend.

In addition, it is possible to generate seasonal usage patterns by combining the usage patterns by season after generating the usage patterns monthly, and it is also possible to perform power saving control according to the season. In the case of a water purifier, there is a significant difference in the amount and temperature of hot water used in winter and in summer, and in the case of a bidet, there is a large difference in the temperature of washing water for washing a local part. Accordingly, it is possible to save power consumed by the device 200 such as the water purifier and the bidet by using the seasonal usage pattern.

2 (a) is an example of a usage pattern generated by the usage pattern generation unit 10 of the power saving control device 100 according to an embodiment of the present invention. Is a weekly usage pattern for a water purifier generated by accumulating and recording for one week.

Referring to FIG. 2 (a), the operation time (a) is mainly distributed between 7:00 am and 8:00 pm, between 1:00 pm and 2:00 pm, and between 7:00 pm and 8:00 pm. That is, it can be confirmed that the water purifier is frequently used at a meal time. Therefore, it is possible to save the power consumed by the water purifier, in particular, the power consumed for generating the hot water, by supplying the operating power before and after the meal time and by supplying the power saving power other than the meal time.

Here, the operation time (a) represents the time at which the water purifier was actually used in the past, and it can be seen that the water purifier is likely to be used again at a position where the operation time (a) is concentrated. Therefore, in consideration of the degree of compactness of the operation time (a), a section for supplying the operating power is extended for a section in which the operation time (a) is concentrated, and a section for supplying the operation power It is necessary to reduce the section for supplying the operating power.

Referring to FIG. 2 (a), the operation time (a) may be concatenated to be set as an operation period (b). Specifically, if the time interval between the operation time (a) is within a predetermined time interval (d), the time interval between the operation time (a) and the operation time is set to one operation period (b) . The fact that the time interval between the operation times is close means that the water purifier is more likely to operate again between the time intervals and that the time interval between the operation times is long means that the probability that the water purifier will operate again It can mean low. Therefore, if the time interval between the operation time (a) is within the predetermined time interval (d), one operation period (b) is set and the operation power is supplied to the device 200 during the operation period (b) can do.

That is, as shown in FIG. 2 (a), since the operation time (a) is concentrated between 7:00 am and 8:00 am and corresponds to within the predetermined time interval (d) And one operation period (b) including each time interval. This is also the case between 1 pm to 2 pm and 7 pm to 8 pm.

However, in the case of the operation time generated at 1:00 am in FIG. 2 (a), since there is no other operation time within the predetermined time interval d, a separate operation period (b) may not be set. That is, since only one operation is performed at 3:00 am for one week, the water purifier is less likely to operate at 3:00 am again. Accordingly, the power saving power, which is not the operating power, can be applied to the water purifier for 3 o'clock in the morning.

As described above, the usage pattern for the water purifier can be generated as shown in Fig. 2 (a) by setting the operation period (b) after accumulating and recording the operation time (a) on the basis of 24 hours, And power can be supplied to the water purifier using the usage pattern.

2 (b) shows an example in which the power supply control unit 20 of the power saving control apparatus 100 according to the embodiment of the present invention supplies electric power to the water purifier according to the usage pattern of FIG. 2 (a) , The operation of the power source control unit 20 will be described with reference to FIG. 2 (b).

The power control unit 20 can adjust the power supply to the device 200 according to the usage pattern. The period set in the operation pattern b in the usage pattern is a period during which the device 200 is expected to be used and the operation power can be applied to the device 200 during the operation period b. Here, the operating power may be the power required for the device 200 to perform a normal operation.

On the other hand, a period other than the operation period (b) is a period in which the device (200) is expected to be unused, so that power saving power is applied to the device (200) can do. Here, the power saving may be the minimum power for the device 200 to wait for operation. The power control unit 20 may limit the amount of power supplied to the device 200 by the power source 300 and supply the reduced power to the device 200. Further, Can be blocked.

Referring to FIG. 2 (b), P1 is a graph showing power consumption in a water purifier according to a conventional power saving control method, and P2 is a graph showing power consumption in a water purifier according to power saving control using the usage patterns. Here, the higher the position of the graph, the more power is consumed.

In the case of P1, conventionally, the power saving control is performed by simply using an illuminance sensor and cutting off the power supplied to the water purifier at a predetermined cycle at night. That is, since the use of the water purifier can not be predicted in advance, the amount of electricity supplied to the water purifier can not be actively reduced, and the amount of electricity saved by the power saving control is also insignificant.

On the other hand, in the case of P2, since the power saving control is performed in consideration of the usage pattern of the user, operating power is supplied so that the water purifier can perform a normal operation in the operation period, . Therefore, when compared with the above-mentioned P1, it is possible to more effectively save the amount of power wasted in the time period when the water purifier is not actually used. Here, it can be seen that P2 is more power-saving than P1, as shown by the hatched portion in Fig. 2 (b).

When the power supply control unit 20 supplies power to the water purifier, as shown in FIG. 3, it is possible to divide each interval and supply power corresponding to the interval. In addition, power can be supplied according to the set interval even if the interval is not within the above-mentioned range. That is, it is possible to set the preheating section and the waiting section before and after the operation opening, the preheating power in the preheating section, and the standby power in the waiting section.

In the case of the water purifier, for example, after the electric power supplied to the water purifier is cut off according to the power saving control, in order to supply the hot water of the target temperature immediately required by the user in the operation period, It is necessary to heat the hot water stored in the hot water tank. Then, when operating power is supplied to the water purifier in the operation period, it may be possible to accurately provide the hot water having the target temperature desired by the user. In addition, rather than stopping the power supply to the water purifier immediately after the end of the operation area, it is preferable to supply the standby power during the standby time so as to correspond to the hot water supply demand of the user, which may be present. FIG. 3 shows an example of the preheating period and the waiting period, and the length of the preheating period, the waiting period, and the sizes of the preheating power and the standby power may be variously configured.

However, since the power supply to the water purifier is controlled on the basis of past usage patterns, a problem may occur when the user uses the water purifier in a time zone not set as the operation period in the usage pattern. That is, when the user uses the water purifier in a time zone other than the operation period, the water purifier can not provide the user with the desired hot water.

In this manner, when an input to the apparatus 200, that is, a control signal, or the like is inputted in a section other than the operation section, the apparatus 200 can be supplied with operation power corresponding to the input of the control signal . However, even if the operation power is supplied in response to the input of the control signal, it may take a long time until the user provides the hot water of the desired temperature, which may lead to user dissatisfaction.

Accordingly, the power saving control apparatus 100 according to an exemplary embodiment of the present invention further includes a human body sensor 30 and an illuminance sensor 40, thereby solving a problem that may occur when only the usage pattern is used.

The human body detection sensor 30 senses a human body located within a predetermined distance from the device 200 and may generate a detection signal when the human body is sensed. Here, the human body detection sensor 30 can be any of sensors that are generally used to detect a human body, such as a temperature sensing sensor, a displacement sensor, and an infrared ray sensor.

In general, a user needs to access the device 200 in order to use the device 200, and when the user approaches the predetermined distance, the device 200 may be considered to be used by the user.

In the case of the water purifier or the bidet, the user needs to approach the water purifier in order to extract hot water or cold water from the water purifier. In the case of the bidet, User access is essential for the use of.

Therefore, even when the usage pattern does not correspond to the operation area, the operation power can be supplied to the device 200 when the detection signal is input. On the other hand, if the detection signal is not inputted even though the operation gap is provided, the user may not supply the operation power to the device 200 by determining that the device 200 is not used.

The illuminance sensor 40 measures the brightness of light input to the apparatus 200 and outputs an illuminance value corresponding to the brightness of the light. The illuminance sensor 40 discriminates between night and day using the illuminance sensor 40 . That is, when the illuminance value measured by the illuminance sensor 40 is less than the minimum illuminance value, it is discriminated as night, and when the illuminance value exceeds the minimum illuminance value, it can be discriminated as day. Here, if the night is determined, the power control unit 20 may supply additional nighttime power to the device 200 to reduce the amount of power consumed by the device 200. [ It is also possible to reduce the amount of power supplied to the device 200 by supplying the nighttime power regardless of the usage pattern when the illuminance sensor 40 determines that the nighttime is used Do.

Here, the day and night can be distinguished by using the illuminance sensor 40, in addition to the method of using the minimum illuminance value, the change rate of the illuminance value with time may be used. In the case of distinguishing the night and the day using the rate of change of the illumination value according to the time, that is, the gradient of the illumination value, it is determined that the night and day change only when the illumination value gradually rises or falls with time, It can be excluded if it turns on suddenly, or when the interior light turns off and becomes dark. Therefore, in this case, there is an advantage that the change of actual night and day can be more accurately known.

FIG. 4 is a graph showing a change with time of the illuminance value measured by the illuminance sensor 40 of the power saving control apparatus 100 according to an embodiment of the present invention. Referring to FIG. 4, 40 will be described.

Referring to FIG. 4, the illuminance value gradually decreases with time, and since the illuminance value is measured below the minimum illuminance value (lx_min), it can be discriminated as night after 20:00. Thereafter, there is a sudden rise in illuminance value (C) between 2 o'clock and 3 o'clock in the morning, which can be seen as a situation where the user turns on the interior lamp at night.

Here, strong light of at least a predetermined value (at least the minimum illumination value) is suddenly input to the illuminance sensor 40 for measuring the brightness of light input to the apparatus 200, which means that the user lights the interior lamp, The user can determine that the user intends to use the device 200 if the user has turned on the room lamp where the device 200 is located.

Accordingly, the power control unit 20, which has supplied the nighttime power from 20 o'clock after, generates an unexpected signal when the sudden rise in the illuminance value C is detected, and supplies operating power to the device 200, The device 200 of FIG.

However, since the apparatus 200 may not be used after the interior lamp is turned on, it is possible to use the human body sensor 30 together with the illuminance sensor 40 to control the power saving control Operation can be performed.

That is, when an unexpected signal is generated due to the rise of the illuminance value C, since the user turns on the interior light for the activity, once the preheating power is supplied to the device 200, Since the probability that the user will use the device 200 becomes higher when the user approaches the device 200 to such an extent that the detection signal is generated by the human body detection sensor 30, Operating power may be supplied to prepare for use of the device 200. [

Thereafter, when the illuminance value suddenly becomes dark again and the illuminance value decreases below the preset value, it can be regarded that the user turns off the indoor lamp, and in this case, the power supply to the apparatus 200 can be immediately blocked , The device 200 may be supplied with standby power during the standby time so as to prepare for the use of the device 200 of the user who may be thereafter.

For example, the water purifier may be located in a dark kitchen at night. At this time, the power supply controller 20 may limit the power supply to the water purifier to a minimum according to the usage pattern or the light intensity sensor 40 . Thereafter, the user can turn on the interior lamp of the kitchen suddenly while entering the kitchen, and the illuminance sensor 40 located in the water purifier can measure the illuminance value higher than a predetermined value. In this case, the power control unit 20 generates an unexpected signal and supplies operating power to the water purifier to prepare for the use of the user's water purifier.

When the user turns on the interior light of the kitchen at the late night and enters the kitchen, it can be expected to use the water purifier in many cases. Therefore, before the user uses the water purifier, have.

However, the user may not use the water purifier, such as a microwave oven, instead of using the water purifier. In contrast, when the outbreak signal is input, preheating power is first supplied to the water purifier, and then, when the body sensor 30 detects the human body and generates a detection signal, it can supply operating power to the water purifier. The user can determine that the user wants to use the water purifier when the interior light is turned on and the user approaches the water purifier. In this case, when the detection signal is generated together with the outbreak signal, the hot water is rapidly supplied, so that the water purifier can quickly cope with the user's use of hot water.

5 is a graph illustrating an example in which the power controller 20 of the power saving controller 100 according to an exemplary embodiment of the present invention supplies power according to a usage pattern, a sensing signal, and an illuminance value. Specifically, P 1 is a graph showing the power consumption of the water purifier according to the conventional power saving control method, and P 3 is a graph showing power consumption of the water purifier when the power saving control is performed according to the usage pattern (b) It is a graph showing the power consumed.

It is possible to supply power by considering the sensing signal s by the human body detection sensor 30 in addition to the usage pattern b as compared with the usage pattern b in FIG. s) is inputted, it can be confirmed that the operation power is continuously supplied.

In addition, although there is no use pattern (b) set in advance near 2 o'clock in the morning, it can be confirmed that the power supplied to the water purifier suddenly rises due to the detection signal (s). This is different from P2 in FIG. 2 (b), since the human body sensor 30 is used in the case of P3, there is an advantage that it can cope with a user's operation in a section other than the usage pattern (b). Here, the shaded portion represents the amount of power saved in the case of P3 in comparison with P1.

6 is a schematic diagram showing a water processor including a power saving control device according to an embodiment of the present invention.

6, the water processor may include a filter portion f, a heater h, a water outlet valve v1, a hot water outlet valve v2, and a power saving control device 100. [

Hereinafter, a water processor according to an embodiment of the present invention will be described with reference to FIG.

First, the water processor may be used for various purposes such as processing wastewater or the like, producing ultrapure water, or the like for industrial use or domestic use (including business use), and particularly relates to a water treatment machine used for drinking. The water processor for drinking water may be collectively referred to as a water purifier in a narrow sense since water is supplied and filtered to generate purified water for drinking. As described above, the water purifier is configured to be able to supply the user with the purified water at room temperature filtered by the filter unit, and can supply the user with hot water and / or cold water by heating / cooling the purified water at normal temperature .

The water handler for drinking includes not only water but also functional water which supplies various functional water such as ionized water, carbonated water, and oxygenated water. In addition, there may be a water heater, a water cooler, and an ice maker for heating or cooling water supplied from a water bottle or the like or generating ice. Therefore, the water treatment unit can be used as a generic term for the water purifier, the functional water machine, the water heater, the water cooler, the ice water heater, and the like and a device having a combination of these functions.

The filter unit f removes particulate impurities, heavy metals and other harmful substances contained in the raw water such as tap water or natural water introduced into the water treatment unit by filtering the incoming raw water.

Specifically, the filter unit f may be a sediment filter, a pre-carbon filter, a reverse osmosis membrane filter, a post-carbon filter, The number and the order of the filters may be variously changed according to the filtration method of the water processor or the filtration performance required by the water processor. . For example, a pretreatment composite filter in which the sediment filter and the pre-carbon filter are integrated may be used, and an ultrafiltration filter may be provided instead of the reverse osmosis membrane filter. It is also possible that a micro filter or another functional filter is provided instead of or in addition to the above-described filter.

The sediment filter is capable of filtering foreign matter and suspended matters contained in raw water by applying a nonwoven fabric, and the free carbon filter is capable of filtering chlorine components and odors contained in raw water by applying surfactant charcoal. The reverse osmosis membrane filter can filter fine particles of about 0.001um, and the post-carbon filter is superior to the surface activated carbon of the pre-carbon filter in adsorbing power, so that the pigment and odor can be removed. The hollow fiber membrane filter can filter the bacteria contained in the raw water by applying a hollow fiber membrane.

The heater h may be one which heats the purified water stored in the hot water tank of the water processor, by heating the purified water to generate hot water of a target temperature desired by the user. That is, in order to use the hot water of the user, the purified water stored in the hot water tank may be continuously heated and maintained at a constant temperature. In this case, since the amount of power consumed in the operation waiting time in which the hot water is not actually used is large, the amount of power consumed in the operation waiting time can be minimized by using the power saving control device 100.

As described above, the usage pattern generation unit 10 of the power saving control apparatus 100 can generate a usage pattern for use of the hot water of the water handler, specifically, the hot water outlet valve v2, So that the usage pattern can be generated. Since the opening and closing of the hot water outflow valve v2 is controlled by the main control unit of the water processor, it is possible to generate the usage pattern by sensing a control signal for opening and closing the hot water outlet valve v2 generated by the main control unit . Alternatively, if the input requesting the user to provide hot water is input to the water number processor in the form of an electrical signal, it is also possible to generate the usage pattern by sensing the electrical signal.

The power control unit 20 of the power saving control device 100 determines whether the usage pattern generated by the usage pattern generation unit 10, the detection signal of the human body detection sensor 30, The power supply to the heater h can be adjusted. More specifically, the operating pattern may supply the operating power during the operating period and may supply the power saving power during the operating period other than the operating period, and may supply the operating power when the sensing signal is input even during the operating period. Also, it is possible to prepare for the case where the user suddenly uses the water handler at night by using the illuminance sensor 40.

Here, the water processor may include a cooler for cooling the purified water in place of the heater (h). The cooler is used to cool the purified water by using a thermoelectric element (TEM) or a refrigerant gas. Like the heater (h), the cooler constantly cools the coolant stored in the cold water tank . Therefore, since the cooler consumes a large amount of power consumed during the operation standby time, the power saving control device 100 may be utilized to reduce the amount of power consumed during the operation standby time.

The water processor may include at least one of the heater h and the cooler, and may include the heater h and / or the cooler to form a water temperature controller. That is, the water processor may include a water temperature regulator including at least one of a heater h for heating the purified water and a cooler for cooling the purified water to generate an integer having a target temperature.

Here, the power saving control device 100 may generate a usage pattern for each of the heater h and the cooler, and perform a power saving control operation for each of the heater h and the cooler.

Additionally, although not shown, there may be a bidet including a power saving control device according to an embodiment of the present invention. The bidet may include a bidet body, a toilet seat, a nozzle unit, a water supply unit, a human body sensor, an illuminance sensor, and a power saving control unit. Here, the human body detection sensor, the illuminance sensor, and the power saving control device have been described above, and a detailed description thereof will be omitted here.

The toilet seat includes a seat provided on the front of the bidet body for the user to sit on, and the temperature of the seat can be adjusted by heating the seat according to an input target sheet temperature. A heating wire for raising the temperature of the seat may be provided in the seat of the toilet seat portion, and the seat seat may heat the seat by supplying electric power to the heating wire.

Here, the toilet seat portion may continuously heat the hot wire in preparation for seating of the user, but in this case, the amount of power consumed in the standby time during which the user is not actually seated may be excessive. Therefore, the amount of power consumed in the operation waiting time can be minimized by using the power saving control device.

The power saving control device may generate a seating pattern of a user with respect to the change-over seat portion by using a usage pattern generating portion, and more specifically, by using a seating detection sensor included in the change- . The seating detection sensor may sense a pressure applied to the toilet seat by the seating of the user to detect whether or not the user is seated. Accordingly, the power saving control device can adjust the amount of power supplied to the toilet seat portion using the usage pattern, the sensing signal, and the illuminance value, as described above.

The water supply unit supplies washing water to the nozzle unit, and the temperature of the washing water can be adjusted by heating the washing water according to the input target washing water temperature. The nozzle unit can wash the local portion of the user using the washing water supplied by the water supply unit and spray the washing water by adjusting the spray intensity, the spray position and the spray time according to the input nozzle control signal. Here, the water supply unit may include a heater for supplying the raw water from the water supply or the like to the wash water used in the nozzle unit, and heating the wash water.

However, the water supply unit can continuously heat the washing water in preparation for the use of the bidet of the user, as in the case of the toilet seat unit, but in this case, an excessive amount of electric power may be consumed during the operation standby time. Therefore, a usage pattern for use of the wash water can be generated using the usage pattern generator of the power saving control device, and the power saving operation can be performed using the generated usage pattern. Specifically, the usage pattern of the water supply unit can be generated by sensing the washing water spraying of the nozzle unit. As described above, the power saving control apparatus supplies the water supply unit with the use pattern, the sensing signal, and the illuminance value The amount of power can be adjusted.

7 and 8 are flowcharts illustrating a power saving control method according to an embodiment of the present invention.

7 and 8, a power saving control method according to an exemplary embodiment of the present invention may include a usage pattern generation step S10 and a power source control step S20. In the usage pattern generation step S10, May include an operation time recording process S11 and an operation interval setting process S12.

Hereinafter, a power saving control method according to an embodiment of the present invention will be described with reference to FIGS. 7 and 8. FIG.

The use pattern generation step (S10) can detect the operation of the apparatus and generate a usage pattern for the apparatus. In order to control the power saving of the apparatus, a usage pattern can be generated by grasping a time zone in which the apparatus is mainly used, and power supply to the apparatus can be adjusted based on the usage patterns.

More specifically, the usage pattern generation step S10 may include an operation time recording step S11 and an operation interval setting step S12.

The operation time recording process S11 may cumulatively record the operation time during which the device operates, during a reference period. That is, an interval during which the apparatus operates in a given reference time is repeatedly recorded during the reference period. For example, the operation time during which the apparatus operates in the 24 hours may be accumulated for a week, with 24 hours being a reference time. Here, the reference time and the reference period can be variously selected, and thus various usage patterns such as a weekly usage pattern, a monthly usage pattern, and a seasonal usage pattern can be generated.

The operation interval setting process S12 may include the operation time including the operation time and the time interval if the time interval between the operation times is within a predetermined time interval from the usage patterns generated in the operation time recording process S11 Section. The operation time is recorded from the time when the apparatus starts operation to the time when the operation ends, and it can be determined that the time period during which the operation time is concentrated is a time zone in which the user mainly uses the apparatus. Therefore, it is preferable that the operation period is set to a high operation period in which the apparatus is likely to be used for the time period in which the operation time is dense.

In the usage pattern generation step (S10), the operation time may be recorded, an operation period may be set to generate a usage pattern for the apparatus, and power saving control may be performed on the apparatus using the usage pattern.

The power saving control step (S20) can adjust the power supply to the apparatus according to the usage pattern. Specifically, it is possible to supply the operating power corresponding to the operation area in the usage pattern, and to supply the reduced power in the section other than the operation section. In this case, since the amount of power consumed in the section other than the operation section in which the apparatus is not used can be minimized, waste of power can be prevented.

In the case of supplying the operating power, the preheating period and the waiting period may be set before and after the operating period to supply the preheating power and the standby power, respectively. Since the operation section is a section in which the device can be actually used, power can be supplied to the device in the preheating period before the operation section so that the user can perform a desired operation simultaneously with the start of the operation section. In addition, since there may be a case where the user uses the apparatus again after the operation period, power can be supplied during the standby period to prepare for the standby period.

In addition, in the power saving control step (S20), when the apparatus includes a human body sensor, an illuminance sensor, and the like, the use pattern is generated using the sensing signal generated by the human body sensor and the illuminance value generated by the illuminance sensor It is possible to compensate the power supply control.

Since the usage pattern is generated based on the past operation of the apparatus, there may be an operation of the user deviating from the usage pattern. Therefore, it is possible to cope with the operation of the user who deviates from the usage pattern by using the human body sensor and the illuminance sensor. That is, when the human body detection sensor detects a human body and generates a detection signal, it is possible to supply operation power to the apparatus even when the human body does not correspond to the usage pattern. On the contrary, The operating power may not be supplied.

In addition, when the illuminance not less than the preset value is input to the illuminance sensor suddenly at night, the operating power can be supplied to the apparatus so that the user can prepare for using the apparatus. In this case, it is also possible to supply preheating power to the apparatus first, and then to control the operation power to be supplied only when the human body detecting sensor generates the detection signal.

Additionally, according to another embodiment of the present invention, there may be a bidet with a power saving control function. The bidet b100 having the power saving control function according to an embodiment of the present invention includes a sensor unit b110, a usage pattern analysis unit b120, a usage pattern A storage unit b130, a bidet control unit b140, and an operation unit b150.

The sensor unit b110 is used to acquire information necessary for use of the bidet by the user and analysis of the bidet usage pattern of the user. The sensor unit b110 includes a distance sensor b111, a toilet seat sensor b112, an illuminance sensor b113, b114), and the like.

The distance sensor b111 and the toilet seat sensor b112 are installed at predetermined positions of the bidet to check whether the bidet is used by the user. The use of the distance sensor b111 and the toilet seat sensor b112 to check whether or not the bidet is used corresponds to general matters to those skilled in the art, and a detailed description thereof will be omitted.

The light intensity sensor b113 is installed on the side of the bidet to measure the room brightness.

The temperature sensor b114 is installed in a drying duct (not shown) of the bidet to measure the room temperature.

The usage pattern analyzing unit b120 analyzes the bidet use pattern by the user using the information acquired by the sensor unit b110.

At this time, the usage pattern analyzer b120 may analyze the information acquired for a predetermined period of time (for example, one week) to obtain more reliable bidet usage pattern information and acquire the bidet usage pattern information based on the analyzed information.

Also, the usage pattern analyzer b120 may analyze the usage pattern according to the indoor brightness information obtained by the ambient light sensor b113.

The usage pattern storage unit (b130) stores the bidet usage pattern information analyzed by the usage pattern analysis unit (b120).

The bidet control unit b140 controls the bidet usage pattern information based on the information obtained by the sensor unit b110 and the bidet usage pattern information analyzed by the usage pattern analysis unit b120 or the bidet usage pattern information stored in the usage pattern storage unit b130. And may include a toilet seat temperature control unit b141, a hot water tank heating unit b142, and a hot air temperature control unit b143.

The toilet seat temperature control unit b141 refers to the bidet usage pattern information and stores the toilet seat temperature at a low temperature (for example, 32 degrees) in comparison with the user-set temperature (for example, 32 degrees) during the time when the bidet usage frequency by the user is less than a predetermined reference value For example, 25 degrees). This makes it possible to reduce the energy consumption consumed to maintain the toilet seat temperature unnecessarily.

The hot water tank heating unit b142 controls the hot water tank to be heated only when it is confirmed that the bidet is being used by the user based on the information obtained by the sensor unit b110.

The warm air temperature control unit b143 adjusts the warm air temperature according to the season based on the temperature information acquired by the sensor unit b110. For example, when the room temperature acquired by the sensor unit b110 is low, the hot air temperature is controlled to be the set temperature, and when the room temperature is high, the hot air temperature can be controlled to be lower than the set temperature.

The operation unit b150 receives an input for controlling operation of the bidet from a user, and can be configured in the same manner as an operation unit provided in a conventional bidet.

10 is a view showing an example of a result of analyzing a user bidet use pattern for power saving control according to the present invention.

Referring to FIG. 10, it can be seen that the use of the bidet by a user during one day is not uniformly distributed over time but distributed around a specific time, for example, around morning, lunch, and evening.

Accordingly, by analyzing the bidet use patterns of the user and performing the power saving control of the bidet by using the pattern, the energy saving effect can be further enhanced while ensuring convenience of the user.

The present invention is not limited to the above-described embodiments and the accompanying drawings.
