For example, if water is detected by the high level sensor 152, the controller may determine that the water level is high within the housing 110, and if water is detected by the low water level sensor 153, the controller may determine that the water level is low within the housing 110. can do. When the control unit previously stores the installation heights of the standard water level detection sensor 151, the high level detection sensor 152, and the low water level detection sensor 153, a specific water level within the housing 110 may also be grasped.

The reference water level detection sensor 151 is for detecting the lowest water level in the housing 110. If the heating device 120 is exposed to the air, such as a ceramic heater, if it is overheated and causes a fire or malfunction, the control unit It is preferable to stop the operation of the heating device 120 when water is not detected by the reference water level detection sensor 151 .

Unexplained reference numeral 180 is a safety device for detecting abnormal overheating of the heating device 120 and cutting off the current supplied to the heating device 120, in addition to controlling the heating device 120 by the control unit, steam is doubled. It is desirable to prevent fire or failure of the generator 100.

Meanwhile, the steam generator 100 according to an embodiment of the present invention may further include a temperature sensor 160 for measuring the temperature inside the housing 110 .

The temperature sensor 160 is inserted from the top of the housing 110 into the interior, and the control unit controls the steam in the housing 110, specifically the first space S1, based on the internal temperature measured through the temperature sensor 160. It is possible to determine whether or not it has occurred or to diagnose a failure of the heating device 120 .

The installation location of the temperature sensor 160 is not particularly limited, but according to another embodiment of the present invention, the temperature sensor 160 is not the upper part of the housing 110, but a water level detecting means, preferably a reference water level detecting sensor ( 151 may be inserted into the housing 110.

Control method of clothes handling device

Meanwhile, FIG. 10 is a diagram illustrating a control method of a laundry treatment apparatus according to an embodiment of the present invention.

As shown in FIG. 10, in the control method of the laundry treatment apparatus according to an embodiment of the present invention, the heating device 120 of the steam generating apparatus 100 heats water to generate steam, and the laundry treatment room 11 A steam operation step (S10) providing steam to the inside and a drying operation step (S20) drying the inside of the laundry treatment room 11 by supplying hot air to the laundry treatment room 11 may be included.

FIG. 11 is a step-by-step flow chart embodying the steam stroke step of FIG. 10 .

As shown in FIG. 11, in the steam stroke step (S10), the first water supply step (S101) of supplying water to the housing 110 of the steam generator 100, and the initial steam generation after the first water supply step (S101) An initial water supply step (S110) of supplying water to the high level of the housing 110 of the device 100, and a water supply cycle (T1) using whether or not the high level of the housing 110 is detected after the initial water supply step (S110) Calculate, An intermediate continuous water supply step (S120) of supplying water to the housing 110 based on the number of water supply n calculated according to the water supply cycle T1 may be included.

In the first water supply step (S101), since the clothes treatment course input by the user includes a steam stroke, steam is generated according to the steam stroke in the clothes treatment course, and steam is generated in advance before steam is supplied to the clothes treatment room 11. It may be a step of supplying water to the housing 110 of the device 100.

The initial water supply step (S110) of supplying water to the high level of the housing 110 is a step of entering the steam stroke, operating the heating device 120 (S1101) and generating steam, but, differently from this, the first water supply step (S101) is A predetermined amount of water may be supplied entirely within the housing 110 .

If there is no water contained in the housing 110 and the heating device 120, such as a ceramic heater, is exposed to the air, it may overheat and cause a fire or malfunction. Before entering the stroke and heating the heating device 120, a predetermined amount of water may be supplied in the housing 110.

Here, it is preferable to supply water in the housing 110 until the low water level in the housing 110 is detected.

Specifically, FIG. 12 is a step-by-step flow chart embodying the first water supply step of FIG. 11 .

As shown in FIG. 12, in the first water supply step (S101) according to an embodiment of the present invention, first, the water level of the housing 110 of the steam generator 100 is detected using the water level detecting means 150 ( S1011) can be done.

At this time, when the control unit detects the low water level of the housing 110 by the water level detecting means 150, the initial water supplying step (S101) may be terminated and the initial water supplying step (S110) may be performed. This is because the minimum amount capable of preventing overheating even when the heating device 120 is heated by the operation (S1101) is accommodated in the housing 110.

If, unlike this, the control unit does not detect the low water level of the housing 110 by the water level detection means 150, the water supply pump device may be operated (S1014), but according to a preferred embodiment of the present invention, the water pump Before operating the device (S1014), it may be determined whether the high level of the housing 110 is sensed by the water level detection means 150 (S1013).

Because, since the control unit enters the steam stroke and must control the water level of the housing 110 using the water supply pump device after the initial water supply step (S110), it is necessary to detect the water level of the housing 110 in advance before entering the steam stroke. for determining errors.

Specifically, since the water level of the housing 110 of the steam generator 100 gradually rises from a low water level to a high water level when water is supplied, the controller uses the water level detecting means 150 by performing steps S1012 and S1013. When the low water level of the housing 110 is not detected, but the high water level of the housing 110 is detected, it is determined that there is a water level detection error due to a failure of the water level detection means 150, and outputs to the outside using various signals (S1015).

If the control unit determines that there is a water level detection error before entering the steam stroke, the steam stroke may be entered and the steam stroke step (S10) may be ended without operating the heating device 120. Of course, at this time, it is preferable that the control unit does not perform the drying process step (S20) as well.

Thereafter, the control unit may enter the steam stroke and perform the initial water supply step (S110).

13 is a step-by-step flow chart embodying the initial water supply step of FIG. 11;

As shown in FIG. 13, in the initial water supply step (S110) according to an embodiment of the present invention, when entering the initial water supply step (S110), the control unit uses the temperature sensor 160 to vaporize in the housing 110. The heating device 120 may be operated until the temperature of the steam outlet 130 through which steam is discharged to the outside or the temperature within the housing 110 reaches a predetermined temperature (S1102).

That is, the control unit compares the temperature of the housing 110 or the steam outlet 130 measured using the temperature sensor 160 with the preset temperature until it is equal to or higher than the preset temperature (S1102). The heating device 120 may be operated (S1101). Here, the predetermined temperature is a temperature at which water can boil and vaporize, and may be, for example, 95° C. or higher.

Then, the control unit according to an embodiment of the present invention operates the water pump device (S1104), but determines whether the high level in the housing 110 of the steam generator 100 is detected by the water level detecting means 150 (S1105) Thus, the operation of the water supply pump device (S1104) can be continued so that water is supplied to the high level in the housing 110.

The control unit measures the temperature of the housing 110 or the steam outlet 130 using the temperature sensor 160, determines whether the measured temperature has reached the preset temperature (S1102), and then determines whether the measured temperature is the preset temperature. If it has reached, the water supply pump device may be operated (S1104) to supply water in the housing 110, but according to a preferred embodiment of the present invention, the control unit uses the temperature sensor 160 to control the housing 110 or After measuring the temperature of the steam outlet 130 and determining whether the preset temperature has been reached (S1102), before operating the water pump device (S1104), the control unit determines whether a high level in the housing 110 is detected (S1103). )can do.

When entering the initial water supply step (S110), since the water level in the housing 110 of the steam generator 100 may be high or higher, the controller according to an embodiment of the present invention first controls the heating device ( 120) is operated, but the water supply pump device is not operated until the housing 110 is not detected as a high level, and then the water level in the housing 110 can be adjusted to a high level by performing S1104 and S1105.

That is, the control unit first vaporizes the water stored in the housing 110 by continuing to operate the heating device 120 until the high level of the housing 110 is not detected by the water level detecting means 150 (S1103), and once the water level After lowering, the water supply pump device may be operated until the water level in the housing 110 becomes high (S1104).

After all, when entering the initial water supply step (S110), if the water level of the housing 110 is higher than or equal to the low water level, even if the water level exceeds the high level, when entering the intermediate continuous water supply step (S120), the water level of the housing 110 is higher than or equal to the high level. may have a high-level state.

Thereafter, the control unit may perform an initial water supply step (S110) and then an intermediate continuous water supply step (S120).

The intermediate continuous water supply step (S120) according to an embodiment of the present invention largely includes a step of calculating the water supply cycle (T1) and a water supply step of operating the water pump device to supply water to the housing 110. can

Among them, FIG. 14 is a step-by-step flowchart of a method for calculating a water supply cycle according to an embodiment of the present invention.

As shown in FIG. 14, in the step of calculating the water supply cycle in the intermediate continuous water supply step (S120) according to an embodiment of the present invention, the controller starts counting the time using a timer (S1201). ) may be included.

Specifically, upon entering the intermediate continuous water supply step (S120), the control unit may be in a state in which the heating device 120 continues to operate, and at this time, the water level of the housing 110 may be in a state in which a high level is detected. At this time, According to a preferred embodiment, the water level of the housing 110 may not exceed the high water level.

In this state, the control unit can start counting using a timer. At this time, since the heating device 120 continues to operate, after a predetermined time elapses after starting counting, the water stored in the housing 110 is evaporated by vaporization. By going out of the housing 110, the water level of the housing 110 may be lowered from a high level.

Here, the predetermined time may be a time until the high level of the housing 110 is not detected (S1202) by the operation of the heating device 120, and the predetermined time is used herein. Among the terms, it may refer to the water supply cycle (T1).

That is, the control unit may count the time taken until the high level in the housing 110 is not detected in the high water level state in the housing 110 during the operation of the heating device 120, and set this as the water supply cycle T1.

After all, since the output of the heating device 120 of the steam generating device 100 is different for each product, the amount of evaporation or steam discharge generated by the operation of the heating device 120 is different for each product. However, the control unit according to an embodiment of the present invention calculates the water supply cycle T1 and adjusts the number of times of water supply and/or evaporation based on the calculated water supply cycle T1, so that the steam injection amount provided in the laundry treatment room 11 can be constantly adjusted. , it is possible to stably control the heating devices 120 having various outputs that are not identical.

Then, the control unit according to an embodiment of the present invention needs to continuously supply water in the housing 110 to continuously generate steam. That is, in the intermediate continuous water supply step (S120) after the initial water supply step (S110), the control unit may intermittently operate the water supply pump device to supply water as much as the evaporation amount of water.

FIG. 15 is a step-by-step flow chart embodying the intermediate continuous water supply step of FIG. 11 .

As shown in FIG. 15, the control unit according to an embodiment of the present invention performs the first and second water supply steps (S121 and S122) of supplying water to the high level of the housing 110 using a water pump device, At this time, the second water supplying step (S122) may be repeated (S1225) based on the number of times of water supply (n).

Specifically, in the intermediate continuous water supply step (S120), the control unit first performs the first water supply step (S121) to operate the water supply pump device (S1211), but the water level detection means 150 detects the high level in the housing 110 It can operate until (S1212), and when detecting the high level in the housing 110, the operation of the water pump device can be stopped (S1213).

That is, in the first water supply step (S121), the control unit may supply water in the housing 110 using a water supply pump device, but supply water until the water level in the housing 110 reaches a high level.

When entering the first water supply step (S121), since the operation of the heating device 120 is continuing from before, the water level in the housing 110 may not be high, so the control unit uses the water pump device to control the housing ( 110), it is possible to supply water to the high level, and after the water supply is made to the high level, the control unit can stop the operation of the water pump device (S1213).

Here, steps S1211 and S122 may be steps in which water is supplied to the housing 110, and step S1213 may be a step in which water is vaporized by the heating device 120 and evaporated.

That is, throughout the first water supplying step (S121) and the subsequent second water supplying step (S122) according to an embodiment of the present invention, the water supplying section and the evaporating section may be alternately repeated over time.

After the first water supplying step (S121), the control unit enters the second water supplying step (S122), and determines whether the high level in the housing 110 is not detected by the water level detecting means 150 or the water supplying cycle (T1) has elapsed. It can be judged (S1221).

Here, in order to determine whether the water supplying period T1 has elapsed in step S1221, the control unit may start the water supplying period T1 when entering the second water supplying step S122. In other words, the operation of the water pump device in the first water supply step (S121) is stopped (S1213) and then the water supply cycle (T1) is started, or in the process of repeating the second water supply step (S122), the second water supply step ( After the operation of the water supply pump device in S122 is stopped (S1224), the water supply cycle (T1) can be started.

As a result, the control unit according to an embodiment of the present invention may operate the water pump device to supply water up to the high level in the housing 110 when the high level in the housing 110 is not detected by the water level detecting means 150. , Not limited to this, the control unit according to an embodiment of the present invention determines whether the water supply cycle T1 has elapsed (S1221) regardless of whether the high level in the housing 110 is not detected, and operates the water supply pump device. By doing so, water can be supplied to a high level in the housing 110 .

Thereafter, the control unit operates the water supply pump device (S1222) until the high level in the housing 110 is detected by the water level detection means 150 (S1223), but when the high level in the housing 110 is detected (S1223), the water supply pump The operation of the device may be stopped (S1224). That is, after a water supply section in which the water supply pump device is operated to a high level in the housing 110 to supply water, an evaporation section in which water is vaporized by the heating device 120 by stopping the operation of the water supply pump device may follow. .

The second water supplying step (S122) may be repeated (S1225) by the control unit based on the number of times n of water supplying.

Here, the number of times of water supply (n) may be a value obtained by dividing the total stroke time of the intermediate continuous water supply step (S120) or the total stroke time of the initial water supply step (S110) and the intermediate continuous water supply step (S120) by the water supply cycle (T1). (see equation below).

[mathematical expression]

Here, the number of times of water supply (n) may be an integer greater than or equal to 0.

As a specific example, in step S1225, the control unit may determine whether the second water supplying step (S122) is less than the number of times of water supply (n), and if the second water supplying step (S122) is less than the number of water supplying (n), the second water supplying step ( S122) is repeated, and in contrast, if the second water supplying step (S122) is equal to or more than the number of water supplying times (n), the intermediate continuous water supplying step (S120) can be ended.

Eventually, the control unit may repeat the second water supplying step (S122) n-1 times, including the first water supplying step (S121), in the intermediate continuous water supplying step (S120), the water supply pump device by the number of times (n) of supplying water By operating the water supply to the high water level in the housing 110 can be repeated.

Accordingly, the steam generation of the steam generator 100 can also continue without interruption, and since the operation of the water pump device is repeated based on the number of times of water supply n calculated according to the water supply cycle T1, the heating device 120 Even if there is a difference in evaporation amount or steam discharge amount for each product based on the difference in output for each product, steam is provided in the clothes treatment room 11 by adjusting the number of water supply (n) (or number of evaporation) accordingly, so it is irrelevant to the difference in output for each product. Preferably, the control unit may provide a constant amount of steam to the laundry treatment room 11 as much as an intended amount.

On the other hand, an example of the operation of the water supply pump device and the heating device 120 throughout the steam stroke according to an embodiment of the present invention is illustrated in FIG. 17 over time.

As shown in FIG. 17, in the first water supply step (S101), the operation of the heating device 120 is yet to start, but the water supply pump device does not operate if the water level of the housing 110 is higher than the low water level, but otherwise operates. can do.

Thereafter, after entering the initial water supply step (S110), the operation of the heating device 120 can be continued until the steam stroke ends, and the water level in the housing 110 is high in the water supply pump device in the initial water supply step (S110). It can be operated once to become, and the operation can be repeated n times so that the water level in the housing 110 becomes high in the intermediate continuous water supply step (S120).

As described above, in the intermediate continuous water supply step (S120), in the step of calculating the water supply cycle (T1), the water pump device may not operate, but throughout the first and second water supply steps (S121 and S122) The water pump device can repeat operation and stop as many times as n times.

Of course, throughout the first and second water supply steps (S121 and S122) in which the water pump device repeats operation and stop, the heating device 120 continues to operate, and the water pump device stops operating When there is, a section in which steam is generated is formed, and a water supply section and an evaporation section may be alternately and repeatedly arranged.

On the other hand, as described above, in the second water supply step (S122) in the intermediate continuous water supply step (S120) according to an embodiment of the present invention, the water pump device can be operated repeatedly (S1225) as many as n-1 times, At this time, even though the water supply pump device is operated repeatedly as many as n−1 times in the second water supply step (S122), there may be a remaining time within the preset total steam stroke time. Here, the total steam operation time may be a preset time allocated to the steam operation included in the clothes treatment course input from the user, and the total steam operation time is determined by the steam operation in the initial water supply step (S110) entering the steam operation. It may correspond to a section up to the intermediate continuous water supply step (S120) that ends.

16 is a step-by-step flowchart of a method of repeating water supply according to another embodiment of the present invention.

As shown in FIG. 16, the controller performs the initial water supply step (S110) and the intermediate continuous water supply step (S120) after entering the steam stroke, and determines whether the remaining time remains, that is, whether the current total steam stroke time has elapsed. A step of doing (S1227) may be further included.

Specifically, after performing the second water supplying step (S122) once, the control unit determines whether the second water supplying step (S122) has been repeated less than n times (or as many as n times in the intermediate continuous water supplying step (S120)) (S1225) And, if the second water supplying step (S122) is repeated n-1 times, it is determined whether there is the remaining time, and if there is, it is determined (S1226) whether the remaining time is less than the water supplying period (T1). can

That is, when the controller repeats the second water supplying step (S122) less than n-1 times, the second water supplying step (S122) is additionally repeated, and the second water supplying step (S122) is n-1 times. If the remaining time is less than the water supply cycle (T1) (S1226) after performing one or more times, it is determined whether the entire steam stroke time has elapsed (S1227), and if the current steam stroke time has not elapsed, the steam stroke is performed immediately. Alternatively, the steam operation may be terminated after waiting for the remaining time (a pause time may be provided) in consideration of the relationship with other follow-up operations.

When the steam stroke ends, it is preferable that the control unit does not operate the feed water pump device any more so that additional water is not supplied in the housing 110 . In addition, it is preferable to stop the operation of the heating device 120 so that steam is no longer provided in the laundry treatment room 11 .

If, in step S1227, the control unit determines that the entire steam stroke time has elapsed, or in step S1226, the control unit repeats the second water supplying step (S122) n-1 or more times, but the remaining time is the water supply cycle (T1). If it is determined that there is an abnormality, it is determined that an error has occurred in the calculation of the water supply cycle (T1) or a failure has occurred in the water supply pump device, and a steam generation error can be output to the outside (S1230).

When a notification about the steam generation error is output (S123), the control unit may stop the operation of the water pump device and the heating device 120 and then end the steam administration step (S10). At this time, the inside of the laundry treatment room 11 Since a humid atmosphere may be formed thereafter, a drying process step (S20) may be performed.

Meanwhile, the control unit according to an embodiment of the present invention may perform the drying operation step (S20) after the steam operation step (S10) is finished (see FIG. 10).

By performing the steam administration step (S10), a humid atmosphere is formed inside the laundry treatment room 11. As a result, there is a concern that mold may occur in the laundry treatment room 11, and clothes accommodated in the laundry treatment room 11 may also get wet due to a humid atmosphere. Therefore, the control method according to an embodiment of the present invention , When the steam stroke (S10) is normally terminated, as well as after various abnormal terminations such as a steam generation error (S1230) or a lack of water in the housing 110, the control unit supplies hot air to the clothes treatment room (11). It is preferable to perform the drying process step (S20).

In order to supply hot air in the clothes treatment room 11, a heater capable of heating air (for example, an electric heater or a gas heater) or a heat pump may be provided inside the machine room 20, but in one embodiment of the present invention As described above, the laundry treatment apparatus according to the present invention may provide dehumidified or heated air in the laundry treatment room 11 by using a heat pump device.

Meanwhile, the steps shown in FIGS. 10 to 16 described above or the steps according to an embodiment of the present invention described above are not essential, so a control method having more steps or fewer steps may be implemented.

In the above, preferred embodiments of the present invention have been described in detail with reference to the drawings. The description of the present invention is for illustrative purposes, and those skilled in the art will understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention.
