In another embodiment of the present specification, the home appliance control unit 110 extracts a first temperature value from each of the plurality of first thermal image images through the temperature calculation unit 114, and if all of the extracted first temperature values do not match The average value of the extracted first temperature values can be selected as the first temperature value. Likewise, the home appliance control unit 110 extracts a second temperature value from each of the plurality of second thermal image images through the temperature calculation unit 114, and if all of the extracted second temperature values do not match, the extracted second temperature value The average value can be selected as the second temperature value.

The home appliance control unit 110 can calculate an accurate temperature value by extracting a first temperature value and a second temperature value from a plurality of first thermal image images and a plurality of second thermal image images, and calculate an accurate emissivity through this. Customized administration can be performed depending on the type of tableware.

Meanwhile, emissivity has a value between 0 and 1. The emissivity is a value predetermined by experiment and may have different values depending on the type of tableware and the material of the tableware. Taking the material of tableware as an example, glass has an emissivity of 0.92, wood has an emissivity of 0.90, plastic has an emissivity of 0.84, stainless steel has an emissivity of 0.59, and stainless steel has an emissivity of 0.92. In the case of stainless plate materials, each has an emissivity value of 0.34.

However, the dishes accommodated in the racks 101 and 102 may not accommodate only one material, but may accommodate a mixture of two or more materials. In this case, the total emissivity may vary depending on the emissivity of each material of the received dishes and the amount of the received dishes.

However, according to the present specification, even when tableware of two or more materials are mixed and accommodated in the rack, if only the first temperature value and the second temperature value are obtained, the home appliance control unit 110 determines the tableware through the emissivity calculation unit 115. The emissivity can be calculated, and it can be determined what type of dishes are accommodated in the racks 101 and 102 or whether the dishes made of a predominant material are stored. Accordingly, the home appliance control unit 110 may perform a third operation according to the determined type of tableware.

The home appliance control unit 110 may determine the third administration through the administration decision unit 116. The third administration may include a basic administration, an additional drying administration, and an additional rinsing administration, and the administration decision unit 116 may select one of the administrations to determine the administration to be performed in the next step.

When the third stroke is determined to be an additional drying stroke, the home appliance control unit 110 performs an additional drying stroke through the drying device 112, and when the third stroke is determined to be an additional rinsing stroke, the washing motor located at the lower part of the tub 108 (107) is controlled, and washing water is sprayed into the tub through the lower nozzle (104b) connected to the sump (106) and the upper nozzle (104a) and top nozzle (104c) connected to the washing water flow path (109) to perform an additional rinsing cycle. It can be done.

Figure 8 is a flowchart showing the step-by-step administrative operation sequence of a dishwasher according to an embodiment of the present invention.

Referring to FIG. 8, the dishwasher 10 according to an embodiment of the present invention operates in the following stages: preliminary washing (S101), main washing (S103), rinsing (S105), heated rinsing (S107), and drying (S109). can do.

When a user loads used dishes into the racks 101 and 102 of the dishwasher 10, food residue may remain on the dishes. Therefore, the dishwasher 10 can perform preliminary washing (S101) in the first cycle. During the preliminary washing (S101) process, the detergent is not guided to the bottom of the tub, so the bulky food on the dishes is first removed using only the washing water without detergent.

The dishwasher 10 performs the main washing (S103) process after the preliminary washing (S101). When the dishwasher 10 performs the main washing (S103) of dishes using only washing water and no detergent, oil stains on the dishes are not washed well, so the dishes are washed by removing oil stains through main washing using detergent.

After the main washing (S103) is completed, the dishwasher 10 discharges the used washing water to the outside through the sump 106, supplies new washing water, and performs a rinsing (S105) process.

Afterwards, the dishwasher 10 performs a heated rinse (S107) cycle using high-temperature heated washing water, rinsing the dishes once again and simultaneously raising the temperature of the surface of the dishes, allowing moisture on the surface of the dishes to easily evaporate in a short period of time. Let it happen.

Finally, the dishwasher 10 dries the dishes by performing a drying (S109) process and completes all steps necessary for washing the dishes.

Figure 9 is a diagram showing the basic concept of changing the washing course according to an embodiment of the present invention.

Referring to FIG. 9, the basic operation for changing the washing course according to an embodiment of the present invention is to first run the terminal application (ThinQ App) on the user terminal 20 and send a standard course command for the washing cycle to the dishwasher ( Send to 10).

Here, the standard course command sent from the user terminal 20 may be wirelessly transmitted directly to the dishwasher 10 or may be transmitted to the dishwasher 10 via the management server 30.

Accordingly, the dishwasher 10 performs a washing operation in a standard course according to the standard course command. For example, the standard course may perform one of the above-described preliminary washing (S101), main washing (S103), rinsing (S105), heated rinsing (S107), and drying (S109).

At this time, the dishwasher 10 may generate a washing noise of, for example, 45 to 55 decibels (dB), which is unpleasant to the human ear, due to a washing operation according to a standard course.

Accordingly, for example, while the user is watching TV in the living room, his or her TV viewing may be interrupted by the washing noise generated from the dishwasher 10.

Therefore, the dishwasher 10 according to the present invention changes the washing course with a washing noise of 45 to 55 decibels (dB) to a low-noise course with a noise level that is, for example, 4 decibels (dB) lower than the washing course by receiving a course change signal. So it works.

The user checks the current washing course of the dishwasher 10 through the terminal application (ThinQ App) of the user terminal 20, and changes to the low noise course as follows according to the washing course control method according to the embodiment of the present invention. Run.

The user terminal 20 changes the washing course by changing the operation mode, for example, from the standard course operation at 01:00 hours to the low noise course operation at 01:40 hours according to the user's operation.

Here, the low-noise course changes the washing operation so that the noise caused by the operation of the dishwasher 10 changes to, for example, 41 to 51 decibels (dB), which is 4 decibels (dB) lower than the 45 to 55 decibels (dB) of the standard course. is to execute.

Figure 10 is an operation flowchart illustrating a method of controlling a washing course of a management server according to an embodiment of the present invention.

Referring to FIG. 10, the server communication unit 310 of the management server 30 according to an embodiment of the present invention receives a course change signal from the user terminal 20 (S1002).

Next, the server control unit 320 checks the washing cycle performed by the dishwasher 10 at the time of receiving the course change signal (S1004).

Here, the dishwasher 10 transmits packet data regarding the operating state to the management server 30 at regular intervals. The management server 30 recognizes the current operating state of the dishwasher 10 through packet data related to the operating state received from the dishwasher 10. Accordingly, the management server 30 recognizes the state of the washing cycle of the dishwasher 10 at the time of receiving the course change signal from the user terminal 20.

Next, the server control unit 320 generates a washing course control command that controls the speed and washing time of the washing motor corresponding to the recognized washing stroke according to the course change signal (S1006).

Next, the server control unit 320 transmits the generated washing course control command to the server communication unit 310 (S1008).

Next, the server communication unit 310 transmits the washing course control command received from the server control unit 320 to the dishwasher 10 (S1010).

In step S1004, if the server control unit 320 determines that the washing cycle performed by the dishwasher 10 at the time of receiving the course change signal is a prewash cycle, the server control unit 320 selects the standard course of the prewash cycle in step S1006. A washing course control command can be generated to change in real time to a low-noise course that reduces the amount of noise generated by 3.7 to 4.0 decibels (dB).

At this time, the server storage unit 330 stores the noise reduction amount for each washing cycle of the dishwasher 10 as data. In addition, the dishwasher 10 also stores the noise reduction amount for each washing cycle as data in the storage unit 150, similar to the noise reduction amount stored in the server storage unit 330 of the management server 30. For example, the amount of noise reduction for each cleaning cycle is 3.7 to 4.0 decibels (dB) for the pre-cleaning cycle, 3.6 to 5.0 decibels (dB) for the main cleaning cycle, 3.9 decibels (dB) or more for the rinsing cycle, and 3.9 decibels (dB) or more for the heat-rinsing cycle. It can be stored in the storage unit 150 at 3.0 to 4.2 decibels (dB).

Accordingly, in the management server 30, the server control unit 320 determines the low noise reduction amount corresponding to the pre-washing cycle of the recognized dishwasher 10 from 3.7 to 3.7 based on the noise reduction amount stored in the server storage unit 330. The goal is to generate a cleaning course control command that sets the level to 4.0 decibels (dB).

The biggest cause of noise in the dishwasher 10 is the rotation speed (rotation per minute) of the washing motor that performs the washing process. Therefore, the dishwasher 10 has a noise reduction amount of 3.7 to 4.0 decibels (dB) based on the noise reduction amount stored in the storage unit 150 according to the washing course control command received from the management server 30 during the pre-washing process. Reduce the rotation speed of the washing motor as much as possible.

In step S1004, if the server control unit 320 determines that the washing process performed by the dishwasher 10 at the time of receiving the course change signal is the main washing process, in step S1006, the server control unit 320 determines the standard course of the main washing process. It is possible to generate a washing course control command that changes in real time to a low-noise course that reduces the amount of noise generated from 3.6 to 5.0 decibels (dB).

That is, based on the noise reduction amount stored in the server storage unit 330, the server control unit 320 determines that the low-noise reduction amount corresponding to the main washing cycle of the recognized dishwasher 10 is 3.6 to 5.0 decibels (dB). The goal is to generate a washing course control command that allows

Accordingly, the dishwasher 10 has a noise reduction amount of 3.6 to 5.0 decibels (dB) based on the noise reduction amount stored in the storage unit 150 according to the washing course control command received from the management server 30 during the main washing process. Reduce the rotation speed of the washing motor as much as possible.

If the server control unit 320 determines in step S1004 that the washing cycle executed by the dishwasher 10 at the time of receiving the course change signal is a rinsing cycle, the standard course of the rinsing cycle occurs in step S1006. A cleaning course control command can be created that changes in real time to a low-noise course that reduces the amount of noise by more than 3.9 decibels (dB).

That is, based on the noise reduction amount stored in the server storage unit 330, the server control unit 320 ensures that the low sound reduction amount corresponding to the recognized rinse cycle of the dishwasher 10 is 3.9 decibels (dB) or more. Generating a washing course control command.

Therefore, the dishwasher 10 is washed so that the noise reduction amount is 3.9 decibels (dB) or more based on the noise reduction amount stored in the storage unit 150 according to the washing course control command received from the management server 30 during the rinsing cycle. This reduces the rotation speed of the motor.

If it is confirmed in step S1004 that the washing cycle performed by the dishwasher 10 at the time of receiving the course change signal is a heat rinse cycle, the server control unit 320 changes the standard course of the heat rinse cycle in step S1006. It is possible to generate a washing course control command that changes in real time to a low-noise course that reduces the amount of noise generated from 3.0 to 4.2 decibels (dB).

That is, based on the noise reduction amount stored in the server storage unit 330, the server control unit 320 determines that the low noise reduction amount corresponding to the recognized heat rinse cycle of the dishwasher 10 is 3.0 to 4.2 decibels (dB). The goal is to generate a washing course control command that allows

Accordingly, the dishwasher 10 has a noise reduction amount of 3.0 to 4.2 decibels (dB) based on the noise reduction amount stored in the storage unit 150 according to the washing course control command received from the management server 30 during the heat rinse cycle. Reduce the rotation speed of the washing motor as much as possible.

Figure 11 is a diagram showing an example of a change point for each unit cycle of a dishwasher according to an embodiment of the present invention.

Referring to FIG. 11, the dishwasher 10 according to an embodiment of the present invention makes low noise while operating a standard course for each unit stroke such as prewash, main wash 1, main wash 2, rinse, heated rinse 1, and heated rinse 2. When changing courses, the administration time can be optimized in real time according to customized logic.

Here, the stroke timing matching logic matches compensation at the beginning of the change stroke so that cleaning performance is not affected, as shown in Table 1 below.

For example, when the dishwasher 10 receives a course change signal at the beginning, middle, or end of the main wash 1 cycle (change point = middle period), it performs a compensation operation according to the real-time change to the low-noise course for each unit stroke. It is applied and executed from the start of the main washing 1 process, which is the start of the change process (①). In other words, the dishwasher 10 compensates by matching the compensation time to the beginning of the change process. At this time, the dishwasher 10 operates from the time of change compensation until the end of the course.

In addition, when the dishwasher 10 receives a course change signal at the end of the main wash 2 cycle (change point = end), the dishwasher 10 performs a compensation operation according to the real-time change to the low-noise course at the main wash at the start of the change cycle for each unit stroke. 2 It is applied and implemented from the start of the administration (②).

Additionally, when the dishwasher 10 receives a course change signal at the time of the rinse cycle (③), the dishwasher 10 may apply and execute a compensation operation according to the change cycle to the rinse cycle.

Additionally, when the dishwasher 10 receives a course change signal at the middle of the first heat rinse cycle (④), the dishwasher 10 may apply and execute a compensation operation according to the change cycle at the middle of the first heat rinse cycle.

In addition, when the dishwasher 10 receives a course change signal at the beginning of the second heat rinse cycle (⑤), the dishwasher 10 may apply and execute a compensation operation according to the change cycle at the beginning of the second heat rinse cycle.

The dishwasher 10 according to an embodiment of the present invention can change and set change parameters such as washing motor rpm, washing time, temperature, and Vario for the real-time change time of the low noise mode based on the standard course. Here, rpm represents the rotation speed (rotation per minute) of the washing motor for 1 minute. The dishwasher 10 may include a washing motor for operating the washing pump, a drain motor for operating the drain pump, and a vario motor for changing the flow path of the vario valve.

Therefore, the dishwasher 10 according to the present invention controls the washing motor, which causes the largest noise. In other words, the dishwasher 10 according to an embodiment of the present invention can better implement a low-noise mode as the rotational speed (rpm) of the washing motor is lower, but it must be able to perform a minimum washing operation. The minimum washing operation can be performed by the minimum rotation speed (rpm) of the washing motor at which the spraying arm can be rotated by the spraying pressure of the washing water exiting the nozzle 104 from the tub 108. In addition, the low-noise course can increase the washing time and washing water temperature to meet the corresponding performance.

Vario indicates a change in the spraying position of the spraying nozzle. The spray nozzle includes a top arm (T), an upper arm (U), and a lower arm (L), and each nozzle and the variable valve are connected through a connector. do. The top nozzle sprays washing water vertically downward, and the upper nozzle sprays washing water vertically upward, so dishes stored in the upper rack are washed. The lower nozzle sprays washing water vertically upward, washing dishes stored in the lower rack. Therefore, the dishwasher 10 can control the spray position and spray amount of the spray nozzle that sprays washing water by controlling the vario valve through the vario motor.

The dishwasher 10, for example, proceeds for 2 minutes with respect to the pre-wash (Pre1) cycle, and at the initial point of the pre-wash cycle when a course change signal is received, the rpm of the washing motor (Motor) is adjusted to, for example, the lower side. (L) can be changed from 1620 rpm to 1980 rpm, the top side (U) can be changed from 1530 rpm to 1870 rpm, and the top side (T) can be changed from 1980 rpm to 2380 rpm.

At this time, in the case of Vario change, for example, the cleaning stroke can be controlled by changing the upper, lower, and top positions of the variable valve in the low noise course to be different from each position in the cleaning course.

In addition, the home appliance control unit 110 changes the washing time from 50 seconds (s) to 70 seconds (s) of the washing course to 1240 seconds (s) to 1510 seconds (s) of the low noise course at the initial point of the pre-washing cycle. , the temperature washing time is changed from 54 seconds (s) to 66 seconds (s) in the washing course to 1240 seconds (s) to 1510 seconds (s) in the low noise course, and the temperature is changed from 50 ℃ to 60 ℃ in the low noise course. It can be controlled by changing the course from 57℃ to 70℃.

In addition, the dishwasher 10 can control the washing process of the low-noise course by changing the main washing 1 (Main1) process in the same way as the change to the pre-washing process described above. At this time, the dishwasher 10 may perform a bubble detection operation for 30 seconds after, for example, a 9-minute main washing cycle (Main1).

In addition, the dishwasher 10 performs a bubble detection operation for, for example, 30 seconds and then performs a washing operation for, for example, 10 minutes for the main wash 2 (Main2) cycle, and changes to the same as the main wash 1 cycle described above. The cleaning cycle of the low-noise course can be controlled. At this time, changing the Vario can be done in the same way as changing the pre-cleaning process. In addition, the home appliance control unit 110 may change the washing time, temperature, washing time, and temperature to be the same as main washing 1.

In addition, the dishwasher 10, for example, performs a rinse cycle (Rinse1) for 1 minute, changes the speed of the washing motor at the beginning of the rinse cycle, changes the lower side (L) from 1620 rpm to 1980 rpm, and changes the upper side L to 1620 rpm to 1980 rpm. By changing (U) from 1530 rpm to 1870 rpm and top side (T) from 1980 rpm to 2380 rpm, the washing cycle of the low noise course can be controlled.

In addition, the dishwasher 10, for example, performs a heated rinse 3 (H_Rinse3) cycle for 6 minutes, and at the beginning of the heated rinse 3 cycle, the washing time is changed from 50 seconds (s) to 70 seconds (s) of the washing course. The low noise course is changed from 1240 seconds (s) to 1510 seconds (s), and the upper, lower, and top positions of the vario valve of the low noise course are changed to be different from each position of the washing course, so that the cleaning cycle of the low noise course is changed. You can control it.

In addition, the dishwasher 10 performs a heated rinse operation for, for example, 4 minutes or 1 minute for the heated rinse 4 (H_Rinse4) cycle, and changes to a low noise course in the same manner as the heated rinse 3 (H_Rinse3) cycle described above. You can control it. Additionally, the dishwasher 10 may perform the heat rinse 5 (H_Rinse5) cycle for, for example, 1 minute after the heat rinse 4 (H_Rinse4) cycle.

FIG. 12 is a flowchart illustrating a method for controlling a washing course of a dishwasher according to an embodiment of the present invention.

Referring to FIG. 12, in the dishwasher 10 according to an embodiment of the present invention, the function performing unit 130 performs a washing course (S1202).

For example, the function performing unit 130 may perform one of the pre-cleaning process, main washing process, rinsing process, and heat rinsing process.

Next, the input units 120 and 140 receive a course change signal commanding to change the washing course to a low noise course with a lower noise level than the washing course (S1204).

For example, the communication unit 120 may receive a course change signal from the user terminal 20 or a washing course control command from the management server 30.

Additionally, a course change signal can be received from the user interface unit 140 through manipulation according to the user's menu selection.

Next, the home appliance control unit 110 recognizes the washing cycle of the washing course currently being performed in the dishwasher 10 (S1206).

For example, the home appliance control unit 110 may recognize one of the pre-washing process, main washing process, rinsing process, and heat rinsing process.

Next, the home appliance control unit 110 controls the washing stroke of the low noise course by changing the speed of the washing motor of the low noise course corresponding to the recognized washing stroke (S1208).

At this time, the home appliance control unit 110 may control the washing process of the low-noise course by lowering the speed of the washing motor of the low-noise course than that of the washing course.

Additionally, the home appliance control unit 110 may control the washing cycle of the low-noise course by changing the washing time of the low-noise course or the temperature of the low-noise course.

Here, when the washing process of the currently recognized washing course is the pre-washing process or the main washing process, the home appliance control unit 110 controls the speed of the washing motor at the initial point of the pre-washing process or the main washing process, 1800 below the washing course. to 2600 rpm, the lower side (L) is changed to 1620 rpm to 1980 rpm, the upper side of the washing course is changed from 2500 to 2600 rpm, the upper side (U) is changed to 1530 rpm to 1870 rpm, and the upper side of the washing course is changed from 2200 to 2500 rpm. By changing the top side (T) from 1980 rpm to 2380 rpm, the washing cycle of the low noise course can be controlled. That is, the home appliance control unit 110 can control the speed of the washing motor at a speed that is 10 to 40% lower than the speed of the washing course.

In addition, the home appliance control unit 110 adjusts the washing time at the initial point of the pre-cleaning process or main washing process from 50 seconds (s) to 70 seconds (s) of the washing course to 1240 seconds (s) to 1510 seconds (s) of the low noise course. ), or change the temperature washing time from 54 seconds (s) to 66 seconds (s) of the washing course to 1240 seconds (s) to 1510 seconds (s) of the low noise course, or change the temperature to 50 ℃ to 50 ℃ of the washing course. The cleaning cycle of the low noise course can be controlled by changing from 60°C to 57°C to 70°C of the low noise course, or by changing the upper, lower, and top positions of the vario valve of the low noise course to be different from each position of the cleaning course.

In addition, when the washing stroke of the currently recognized standard course is a rinse stroke or a heat rinse stroke, the home appliance control unit 110 sets the lower side (L) to 1620 with respect to the speed of the detail chuck motor at the initial point of the rinse stroke or heat rinse stroke. By changing the rpm to 1980 rpm, changing the upper side (U) to 1530 rpm to 1870 rpm, and changing the top side (T) to 1980 rpm to 2380 rpm, the washing cycle of the low noise course can be controlled.

In addition, the home appliance control unit 110 adjusts the washing time at the initial point of the rinse cycle or heat rinse cycle from 50 seconds (s) to 70 seconds (s) of the wash course to 1240 seconds (s) to 1510 seconds (s) of the low noise course. Alternatively, the cleaning stroke of the low-noise course can be controlled by changing the upper, lower, and top positions of the variable valve of the low-noise course to be different from each position of the cleaning course.

Meanwhile, the storage unit 150 of the dishwasher 10 may store data in which the washing performance score for each washing cycle is calculated based on internal test standards. Accordingly, the management server 30 generates a washing course control command containing a washing performance score corresponding to the currently recognized washing cycle of the dishwasher 10 based on the washing performance score stored in the server storage unit 330 to wash the dishes. It can be transferred to the washing machine (10).

Therefore, when the point in time at which the washing course is changed to the low-noise course is the pre-washing process or the first main washing process, the home appliance control unit 110 can control the washing performance by changing it from the score of the standard course to the score of the low-noise course. .

In addition, the home appliance control unit 110 selects the current washing course, the pre-washing cycle or the first main washing course, based on the washing performance score stored in the storage unit 150 according to the course change signal input through the input units 120 and 140. In the case of a washing cycle, the washing time, temperature, rotation speed of the washing motor, etc. can be controlled to change from the score of the standard course to the score of the low-noise course.

Additionally, when the point at which the standard course is changed to the low-noise course is the second main cleaning process, the cleaning performance may be changed from the score of the standard course to the score of the low-noise course.

Accordingly, the dishwasher 10 selects the second main wash course, which is the current wash course, based on the wash performance score stored in the storage unit 150 according to the wash course control command received from the management server 30 during the second main wash process. Depending on the washing process, the washing time, temperature, rotation speed of the washing motor, etc. can be controlled to change from the standard course score to the low noise course score.

Additionally, when the change point from the standard course to the low-noise course is the rinsing cycle, the cleaning performance may change from the score of the standard course to the score of the low-noise course.

Accordingly, the dishwasher 10 performs the standard washing cycle according to the rinsing cycle, which is the current washing course, based on the washing performance score stored in the storage unit 150 according to the washing course control command received from the management server 30 during the rinsing cycle. You can control the washing time, temperature, rotation speed of the washing motor, etc. to change the score of the course to the score of the low-noise course.

Additionally, when the point at which the standard course is changed to the low-noise course is the first heat rinse cycle, the cleaning performance may be changed from the standard course score to the low-noise course score.

Accordingly, the dishwasher 10 performs the first heat, which is the current wash course, based on the wash performance score stored in the storage unit 150 according to the wash course control command received from the management server 30 during the first heat rinse cycle. Depending on the rinsing cycle, the washing time, temperature, rotation speed of the washing motor, etc. can be controlled to change from the standard course score to the low noise course score.

Additionally, if the point at which the standard course is changed to the low noise course is the second heat rinse cycle, the cleaning performance may not change from the score of the standard course.

Therefore, the dishwasher 10 performs the second heat, which is the current wash course, based on the wash performance score stored in the storage unit 150 according to the wash course control command received from the management server 30 during the second heat rinse cycle. Depending on the rinsing cycle, the washing time, temperature, rotation speed of the washing motor, etc. can be controlled to maintain the standard course score.

The parameters of the low noise mode may have different values from the parameters of the low noise course. For example, the speed of the washing motor in the low noise mode may be different from the speed of the washing motor in the low noise course.

Additionally, the parameters of the low noise mode may have the same values as the parameters of the low noise course. For example, the speed of the washing motor in the low noise mode and the speed (rpm) of the washing motor in the low noise course are the same, and only the execution time of the same washing cycle in each mode may be different.

Parameters of the low noise mode may include washing water injection pressure, washing time, washing temperature, and speed of the washing motor.

The control unit 110 lowers the washing water spray pressure to the lowest washable spray pressure according to the parameters of the low noise mode, makes the washing time longer than the washing course, increases the washing temperature compared to the washing course, and lowers the speed of the washing motor compared to the washing course. The cleaning cycle can be controlled to run in low noise mode.

The nozzle 104 is connected to the sump 106 and rotates to spray washing water into the tub toward the racks 101 and 102 according to the spray pressure. The lowest spraying pressure that can be washed is the control unit 110 that lowers the speed (rpm) of the washing motor so that the washing process is performed in a low-noise mode, so that the washing water sprayed from the nozzle 104 flows into the racks 101 and 102 adjacent to the nozzle 104. This is the pressure that is sprayed enough to reach the surface. Therefore, the lowest spray pressure capable of cleaning may mean the lowest speed (rpm) of the cleaning motor capable of cleaning in low-noise mode.

The washing process may be one or more of a pre-cleaning process, a main washing process, a rinsing process, a heat rinsing process, and a drying process.

The pre-washing process is a process that circulates the washing water by driving the washing motor without detergent being administered from the detergent dispenser and measures the amount of contamination through a turbidity sensor. The main washing process circulates the washing water with detergent being administered from the detergent dispenser. This is the process of washing dishes by ordering them. The rinse cycle involves rinsing with water without detergent, and the heated rinse cycle heats the dishes with hot water and can help dry the dishes in the upcoming drying cycle. In the rinse/heat rinse cycle, rinse is administered from a detergent dispenser to improve the hydrophilicity of dishes, which can help evaporate water remaining on the surface of dishes during future drying. Each stroke can be omitted, duplicated, or adjusted depending on course settings and options.

The prewashing process is a process in which bulky food on dishes is first removed using only wash water without detergent because the detergent is not guided to the bottom of the tub. The main washing process is performed after the pre-washing process. If the dishwasher performs the main washing of the dishes with only washing water and no detergent, the oil stains on the dishes are not cleaned well, so the main washing using detergent removes the oil stains and cleans the dishes. It is a cleaning process. The rinsing process is a process in which, when the main washing process is completed, the used washing water is discharged to the outside through the sump and new washing water is supplied to perform rinsing. The heated rinse cycle is a process that rinses the dishes again by performing a heated rinse using high-temperature heated washing water and simultaneously increases the temperature of the surface of the dishes so that the moisture on the surface of the dishes can easily evaporate in a short period of time.

Between each stroke, a process of draining the washing water used during the administration and supplying new washing water is included. A water supply process may be included before the pre-washing process. A drainage and water supply process may occur between pre-washing and washing, between washing and rinsing, between heat rinsing and rinsing, and a drainage process may occur between heat rinsing and drying. . Water can be supplied by controlling the Aqua Stop (not shown) of the water supply unit to supply water to the sump through the water supply passage, and by controlling the drain motor connected to the sump, water can be drained out of the sump and the dishwasher through the drain passage. .

Among the main washing process, rinsing process, and heating rinsing process, the execution time of the rinsing process may be longer than that of the main washing process and the heating rinsing process.

Among the main washing process, rinsing process, and heating rinsing process, the execution time of the main washing process may be longer than that of the rinsing process and the heating rinse process.

The dishwasher 10 according to another embodiment of the present invention improves washing performance while reducing noise so that washing performance is not affected even when changing to the low noise mode parameters in real time when changing to low noise mode while executing a normal washing course. In order to maintain the same level, the spray pressure of the washing water can be lowered, the washing time can be increased, and the washing temperature can be increased.

Here, the low noise mode lowers the speed of the washing motor compared to the washing course so that the washing water spray pressure is the lowest spray pressure possible for washing, increases the washing time to maintain the washing performance, and increases the washing temperature to execute the washing cycle. means mode.

If a course change signal is input during the execution of the main washing process of the washing course, the control unit 110 changes the parameters (washing time, washing temperature, etc.) from the washing course to the low noise mode in real time at the time of inputting the course change signal, and Depending on the parameters of the mode, the main cleaning process in low noise mode is controlled to be executed from the input point to the remaining time of the main cleaning process, and thereafter, the main cleaning process in low noise mode is additionally performed for the first time allocated to the main cleaning process in low noise mode. You can control it to run.

For example, while executing a 20-minute main wash cycle, the control unit 110 of the dishwasher 10 selects a low-noise mode signal from the user terminal 20 through an app at the 10-minute main wash cycle. When a course change signal is received, the washing temperature is raised to 50~60℃, the speed (rpm) of the washing motor is lowered to LT2450~2550/L2550~2650/U2500~2600, and the main washing time in low noise mode is set to 20 minutes. And, the function performing unit 130 is controlled to execute the main cleaning process in low noise mode for the remaining 10 minutes of the main cleaning process. Next, the control unit 110 performs the main cleaning cycle in low noise mode at a cleaning temperature of 50 to 60°C and the speed (rpm) of the cleaning motor at LT2450 to 2550/L2550 to 2650/U2500 to 2600 for 20 minutes. Controls this to be executed. Therefore, the main cleaning cycle in low-noise mode is run for a total of 30 minutes, including 10 minutes of the cleaning course and 20 minutes of additional low-noise mode. As described above, the first time allocated to the main cleaning process in low noise mode may be, for example, 20 minutes. The first time allocated to the main cleaning process in the low noise mode according to the embodiment of the present invention is not limited to this.

When a course change signal is input while executing the rinsing cycle of the washing course, the control unit 110 changes the washing course to the low-noise mode parameters (washing time, washing temperature, etc.) in real time at the time of input, and changes the settings according to the low-noise mode parameters. The low noise mode rinsing cycle can be controlled to be executed from the input point until the remaining time of the rinsing cycle, and thereafter, the low noise mode rinsing cycle can be controlled to be additionally executed for the second time allocated to the low noise mode rinsing cycle.

For example, while executing a 25-minute rinse cycle, the control unit 110 of the dishwasher 10 changes the course to the low-noise mode through an app from the user terminal 20 when the rinse cycle has been performed for 15 minutes. Upon receiving the signal, the washing temperature is raised to 62~68℃, the speed (rpm) of the washing motor is lowered to LT2550~2650/U2250~2450, the rinse stroke time in low noise mode is set to 25 minutes, and the rinse cycle of the washing course is set to 25 minutes. Control the rinse cycle in low noise mode to run for the remaining 10 minutes of the cycle. Next, the control unit 110 controls the rinsing cycle in low noise mode to be executed at a washing temperature of 62 to 68°C and a speed (rpm) of the washing motor of LT2550 to 2650/U2250 to 2450 for 25 minutes of rinsing cycle time in low noise mode. Therefore, the rinse cycle in quiet mode runs for a total of 35 minutes, including 10 minutes of the wash cycle and an additional 25 minutes in quiet mode. As described above, the second time allocated to the rinse cycle in the quiet mode may be, for example, 25 minutes. The second time allocated to the rinsing cycle in the low noise mode according to the embodiment of the present invention is not limited to this.

When a course change signal is input while executing the heat rinse cycle of the wash course, the control unit 110 changes the parameters (wash time, wash temperature, etc.) from the wash course to the low noise mode in real time at the point of input, and performs the heat rinse from the point of input. The heating rinse stroke in low noise mode is controlled to be executed according to the parameters of the low noise mode until the remaining time of the stroke, and thereafter, the heating rinse stroke in low noise mode is additionally controlled to be executed for the third time allocated to the heating rinse stroke in low noise mode. You can.

For example, while executing a 3-minute heat rinse cycle, the control unit 110 of the dishwasher 10 selects the low-noise mode mode through an app from the user terminal 20 at the time of executing the heat rinse cycle for 1 minute. When a course change signal is received, the washing temperature is raised to 50~58℃, the speed (rpm) of the washing motor is lowered to LT2450~2550/L2550~2650/U2300~2400, and the heat rinse cycle time in low noise mode is set to 3 minutes. Set and control the rinse cycle in low noise mode to run for the remaining 2 minutes of the heated rinse cycle of the cleaning course. Next, the control unit 110 sets the cleaning temperature to 50 to 58°C and the speed (rpm) of the washing motor to LT2450 to 2550/L2550 to 2650/U2300 to 2400 for 3 minutes for the heating rinse cycle in low noise mode. Control it to run. Therefore, the heat rinse cycle in low noise mode is run for a total of 5 minutes, including 2 minutes of the washing cycle and an additional 3 minutes in low noise mode. As described above, the third time allocated to the heating rinse cycle in the low noise mode may be, for example, 3 minutes. The third time allocated to the heat-rinsing cycle in the low-noise mode according to the embodiment of the present invention is not limited to this.

The control unit 110 lowers the speed of the washing motor compared to the washing course so that the washing water spray pressure is the lowest washable spray pressure for the low-noise mode washing process including the main washing process, rinsing process, and heated rinsing process, and sets the washing temperature. It can be controlled to execute a low-noise mode cleaning cycle by raising it above the cleaning course.

In the low-noise mode, among the first time allocated to the main wash cycle, the second time allocated to the rinse cycle, and the third time allocated to the heat rinse cycle, the first time or the second time is the longest, and the third time is the shortest. It could be time.
