Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a garment processing apparatus and a control method thereof, and more particularly, to a garment processing apparatus and its control method capable of easily grasping whether or not the garment processing apparatus is normally installed.

The clothes processing apparatus is a device for washing or drying clothes such as a washing machine or a dryer. In addition to such washing and drying, a refresher has been recently provided in addition to a washing machine and a dryer provided with a refresh function for removing odors and wrinkles.

These clothes processing apparatuses are equipped with various loads. These various loads are supplied with power and control signals, respectively, and perform corresponding operations.

The garment processing apparatus is generally installed as one apparatus to receive power from the outside, and is connected to various peripheral apparatuses. For example, to be supplied with water from an external water source.

The external water source may be provided to supply hot water as well as cold water, and the clothes processing apparatus should be connected to each water source to receive cold water and hot water.

In the case of a washing machine, a dryer, or a washing / drying machine in a clothes processing apparatus, vibration may be generated due to the driving of the drum. Such vibration may be caused to a greater extent if there is an abnormality in the self-installation of the clothes processing apparatus. For example, in the case of the installation of the clothes processing apparatus, when the level is not leveled or when the rigidity of the installed floor itself is not sufficient, a vibration outside the normal range may be generated.

On the other hand, in the case of a drum washing machine or a dryer, the tub is generally fixed to the cabinet with a shipping bolt or the like when the initial product is released. That is, it is intended to prevent damages such as drums, tubs, cabinets, and suspensions due to a large impact applied to the entire product when the product is transported.

The clothes processing apparatus may have various loads such as a motor, a heater, a drain pump, a steam generator, and the like as well as various valves for receiving cold water or hot water from the outside. It is common to check whether the load itself is normal before the product is released. That is, it is checked whether each of the loads is operating normally during the manufacturing process of the product, and a product that operates normally is released.

However, the environment in which the clothes processing apparatus is installed may vary widely, and the user or installer who installs the clothes processing apparatus may also be very diverse. Therefore, there may arise a problem that the clothes processing apparatus itself is not normally installed irrespective of whether or not each load operates normally.

For example, a cold water valve to which cold water is to be introduced may be connected to an external hot water supply source, and conversely, a hot water valve to which hot water is to be introduced may be connected to an external cold water supply source.

For example, even though the drain pump is operating normally, the drain hose may not properly connect to the outside drain, which may prevent the garment handling device from functioning properly.

For example, the installation position of the garment disposal apparatus may not be leveled or the shipping bolt may not be removed, so that the garment disposal apparatus may not operate properly.

Therefore, even though the various loads themselves are normal, abnormal operation may occur as a whole of the clothes processing apparatus, which may be caused by installation problems. In this case, the user determines that the clothes processing apparatus is abnormal and issues a repair request.

This problem is undesirable for users as well as providers of garment processing devices. This is because the user makes an unnecessary service request, and the provider of the garment processing apparatus (the seller or the garment processing apparatus producer) also provides unnecessary services and wastes time and money. Therefore, it is desirable that the user, the product installer, and the apparel processing apparatus provider can easily grasp whether the clothes processing apparatus is normally installed.

However, it is not very easy to grasp that it is a normal installation when installing the clothes processing apparatus. That is, it is very easy to check whether the various loads are operating normally and whether or not the entire clothes processing apparatus is operated normally. This is because, since the installation of the clothes processing apparatus is performed by a person, there is always room for mistakes and errors.

The present invention basically aims to solve the problem of the above-mentioned conventional clothes processing apparatus.

It is an object of the present invention to provide a garment processing apparatus and a control method thereof that can easily grasp not only the normal operation of various loads of the garment processing apparatus but also whether or not the garment processing apparatus itself is normally installed.

According to an embodiment of the present invention, there is provided a garment processing apparatus and a control method thereof, in which a purchaser (user) and an installer can visually grasp not only whether a clothes processing apparatus is normally installed, but also whether or not various loads are normally operating. Accordingly, the user can improve the reliability of the clothes processing apparatus itself, the installer installing the apparatus, and the supplier supplying the same.

The present invention provides a clothes processing apparatus and a control method thereof that can reduce the time required to install and inspect the clothes processing apparatus efficiently and simply.

An embodiment of the present invention is to provide a clothes processing apparatus and a control method thereof that can easily input the execution of the installation inspection course and easily grasp the execution result.

A clothes processing apparatus and a control method thereof capable of easily checking and correcting problems that may occur during installation such as a mistaken connection between an external cold water supply source and a hot water supply source, Method. That is, the present invention is to provide a garment processing apparatus and its control method capable of confirming and correcting a problem that may occur only during installation, not as a problem of the product itself, as an execution of an installation inspection course.

According to an aspect of the present invention, there is provided a method of controlling a clothes processing apparatus, the method comprising: receiving power from a clothes processing apparatus through a power input unit; Receiving a start of installation inspection course; Performing the installation inspection course by driving the clothes processing apparatus to check whether a plurality of loads of the clothes processing apparatus operate normally and whether the clothes processing apparatus is normally installed; And a notification step of a result of the installation inspection course.

The plurality of loads may be constituted to cause a physical change by an operation. When the electric energy is applied, it can be said to cause a physical change such as water level change, temperature change, air flow, driving of the drum or fan (variable RPM), vibration of the drum or the tub. Therefore, basically, these loads must be operated so that the clothes processing apparatus can perform the garment processing.

The driving of such a load can be sensed and controlled by a plurality of sensors. The sensor includes various sensors such as a temperature sensor, a water level sensor, a vibration sensor, and a hall sensor, and the sensors perform a garment process with a predetermined flow by the feedback control of the sensing result.

In the step of performing the installation inspection course, it is preferable that the predetermined inspection step is performed sequentially for each of the plurality of loads. That is, whether or not the load is normally operated for each load is performed through the corresponding inspection step, and these inspection steps can be performed sequentially. Here, the inspection step is a step of checking not only whether the load itself is abnormal, but also whether it is properly installed. Therefore, each time each inspection step is performed, it is possible to easily determine whether the load is abnormal and whether the installation is abnormal related to the load.

Preferably, the clothes processing apparatus is provided with a course selection unit for selecting a clothing processing course, and the input of the installation inspection course is performed separately from the course selection unit. This is because the use frequency of the installation inspection course is remarkably small and needs to be used only in a very special situation.

Preferably, the garment processing apparatus is provided with an NFC module, and after the power is applied, the installation inspection course input is performed through NFC tagging corresponding to a request to start installation inspection course from the outside. When a normal installation inspection course is inputted, it is preferable that a buzzer sound is generated.

During the installation inspection course, if the NFC tagging corresponding to the installation inspection course start request is performed, the request is preferably ignored. At this time, it is preferable that a buzzer sound is generated, which means that the request is ignored.

If the NFC tagging corresponding to the request for the result of the installation inspection course is performed during the installation inspection course, the progress rate of the installation inspection course may be transmitted to the outside.

The notifying step may include displaying the result of the installation inspection course or transmitting the result to the outside.

The garment processing apparatus is provided with a display, and each time the respective inspection steps are performed, the normal operation of the load can be displayed on the display. And, when the installation inspection course is finished, the result can be displayed on the display. In addition, during the progress of the installation inspection course, it is possible to indicate whether the progress or the inspection step for a certain load is proceeded in the display. It is also possible to display the inspection result of the load each time each corresponding inspection step ends.

It is preferable that the inspection step is started after the operation of all the loads for checking whether the normal operation is performed is stopped in the installation inspection course before the respective inspection steps are started. Therefore, it is possible to prevent the load from being influenced by the operation of another load to be inspected.

Wherein the clothes processing apparatus includes an avalve valve or a cold water valve connected to an external cold water supply source as a load and the installation inspection course includes an inspection step corresponding to the avalve valve or the cold water valve, It is preferable to check whether the water level changes and the temperature rises by the operation of the valve or the cold water valve.

Here, when the avalve valve or the cold water valve operates and the water level rises, the valve itself may be operating normally. However, if there is no change in the water level, it means installation error. This can mean that the faucet, which is the external water source, is locked.

On the other hand, although the water level is rising, a temperature rise exceeding the normal temperature range may not be detected. In this case, it can be determined that the valve is properly connected to the external cold water source. On the contrary, if a temperature rise exceeding the normal temperature range is detected, it is determined that the valve is connected to the external hot water source, so that it can be judged as an installation error.

Wherein the clothes processing apparatus includes a hot water valve connected to an external hot water supply source as a load, wherein the installation inspection course includes an inspection step corresponding to the hot water valve, and in the inspection step, It is desirable to check for changes and temperature increases.

When the water level change due to the operation of the hot water valve, that is, the water level rise occurs, it can be judged that the hot water valve operates properly. However, if the temperature rise beyond the normal temperature range is not detected, it can be judged that the hot water valve is connected to the external cold water source.

On the other hand, both the hot water valve and the cold water valve operate normally, and temperature rise exceeding the normal temperature range may not be detected at all during operation of both. At this time, the installation error may be irrelevant due to the problem of the external hot water source itself. For example, the boiler is turned off or the valve in which the domestic hot water is introduced is locked.

Accordingly, it is possible to grasp the installation error by performing the installation inspection course, and to grasp the state of the external facility connected to the clothes processing apparatus. Therefore, the installer can explain not only the clothes processing apparatus but also the relationship between the surrounding facility and the clothes processing apparatus to the user.

The load may include a valve for supplying cold water, a motor for driving the drum, a heater for heating cold water, a drain pump for draining water, and a valve for supplying hot water.

Wherein the installation inspection course comprises: an inspection step for a valve for supplying cold water; An inspection step for a heater for heating the supplied cold water; An inspection step for a drain pump for draining the supplied water; And a check step sequence for valves supplying hot water. In other words, it is possible to organically arrange the time for generating the water level change and the temperature change, and the operation time point of the loads associated therewith, thereby significantly reducing the time required for the installation inspection course.

It is preferable that the inspection step for the motor is performed with the highest priority and the drainage pump is driven during the inspection step for the motor so that the installation inspection course is performed up to the set water level.

If the drain pump fails to perform the drainage to the set water level for a preset time, it is preferable to terminate the installation inspection course without performing the following inspection steps.

It is preferable to check the model of the garment processing apparatus to be inspected before performing the respective inspection steps and omit the inspection step if there is no load to be performed on the garment processing apparatus. Thus, one installation inspection course can be applied to a wide variety of models.

According to an aspect of the present invention, there is provided a method of controlling a clothes processing apparatus, the method comprising: receiving power from a clothes processing apparatus through a power input unit; Receiving an installation inspection course start via the NFC module; In order to confirm whether or not a plurality of loads of the clothes processing apparatus are normally operated and whether the clothes processing apparatus is normally installed, the predetermined inspection steps are sequentially performed for each of the plurality of loads to perform the installation inspection course step; And transmitting the result of the installation inspection course to an external terminal through the NFC module.

When the power is applied, the start of the installation inspection course can be inputted by the NFC tagging in the initial state of the clothes processing apparatus, that is, without any input to the garment processing apparatus. The installation inspection course may be performed immediately by the NFC tagging, and the installation inspection course may be performed when the input of the start / pause input part is performed.

It is preferable that the inspection step is carried out such that the corresponding load is directly driven. In the case of a valve, it is not only whether the valve is opened, the heater is heated in the case of a heater, the rotation of the rotor in the case of a motor, the driving of the pump in case of a drain pump, It is preferable to operate it directly. The purpose of this study is to identify the abnormalities or errors in the installation of the clothes processing device itself as well as the abnormality of the load itself through physical changes actually occurring due to the operation of the load.

Wherein the clothes processing apparatus includes a plurality of valves for supplying cold water from an external cold water supply source as a load into the tub, the installation inspection course includes inspection steps corresponding to each of the plurality of valves, It is preferable that each of the plurality of valves is inspected for normal operation by inspecting a change in the water level in the tub.

These valves may include cold water valves, bleach valves, avalves valves and condensate valves. Of course, depending on the model, certain valves may be omitted or added.

It is preferable to check the temperature inside the tub before the water supply in the first inspection step among the inspection steps corresponding to each of the plurality of valves and to check the temperature inside the tub after the water supply in the last inspection step.

The inspection sequence of the valves may be a cold water valve, a bleach valve, a condensate valve and an avalanche valve. A temperature check in the tub may be performed before the water supply by the cold water valve, and finally, a temperature check in the tub after the water supply by the avalanche valve. You can check the temperature change through these two temperatures. The change in water level in each step implies normal operation of each valve, which means that these valves are normally connected to the external cold water supply source if no temperature change occurs substantially. Thus, it is possible to check this normal series connection through a single temperature change check.

It is possible to provide a clothes processing apparatus and a control method thereof that can easily grasp not only whether the various loads of the clothes processing apparatus are normally operated but also whether the clothes processing apparatus itself is normally installed or not through the embodiment of the present invention.

According to an embodiment of the present invention, it is possible to provide a garment processing apparatus and a control method thereof, which can visually confirm whether a purchaser (user) and an installer are normally installed, as well as whether or not the clothes processing apparatus is normally installed. . Accordingly, the user can improve the reliability of the clothes processing apparatus itself, the installer installing the apparatus, and the supplier supplying the same.

The present invention can provide a clothes processing apparatus and a control method of the same, to which an installation inspection course can be efficiently and simply installed and inspected by reducing the time required to perform the installation inspection of the clothes processing apparatus.

It is possible to provide a clothes processing apparatus and a control method thereof that can easily input the execution of the installation inspection course and easily grasp the execution result through the embodiment of the present invention.

A clothes processing apparatus and a control method thereof capable of easily checking and correcting problems that may occur during installation such as a mistaken connection between an external cold water supply source and a hot water supply source, Method can be provided. That is, it is possible to provide a clothes processing apparatus and a control method thereof that can check and correct a problem that may occur only during installation, not as a problem of the product itself, as an execution of an installation inspection course.

Figure 2 is a flow diagram illustrating a control flow according to one embodiment of the present invention; And
3 is a detailed control flow of the installation inspection course shown in Fig.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a clothes processing apparatus according to an embodiment of the present invention. Of course, this block diagram may also be a block diagram of a conventional garment processing apparatus.

The garment processing apparatus 100 includes a control unit 10, a user input unit 20, and a plurality of loads 50. The plurality of loads 50 are configured to be driven according to a control command of the controller 10, and are hardware driven to process garments through the clothes processing apparatus.

For example, the clothes processing apparatus 100 is a washing / drying machine in which both a washing function and a drying function can be performed. In a garment processing apparatus having different main functions such as a washing machine, a dryer or a refresher, the specific load may be omitted. In addition, the specific load can be omitted in spite of being the same kind of clothes processing apparatus.

For example, in the case of a washer / drier, the circulation pump 61 may be omitted as needed and the circulation of the wash water may not be performed. If necessary, the steam heater 57 and the steam valve 56 may be omitted and the steam function may not be provided.

For example, in the case of a pure washing machine, the condenser valve 53, the fan motor 62 and the drying heater 63 may be omitted.

Therefore, in the case of the clothes processing apparatus according to the embodiment of the present invention, not only the loads shown in Fig. 1 but also other loads may be included, on the contrary, the specific load may be omitted.

Generally, the provider providing the clothes processing apparatus 100 produces and sells various types of clothes processing apparatuses such as washing machines, dryers, laundry / driers, and refreshers. In addition, various kinds of washing machines are produced and sold even in the case of a specific clothes processing apparatus, for example, a washing machine. They can be divided into models or products and have unique identification codes. Thus, through the identification code, the garment processing apparatus can determine which loads are included and which loads are not included.

That is, the installation inspection course that can be applied to this embodiment means that it can be used for a general purpose in a clothes processing apparatus as well as a specific model. The installation inspection course can be provided to judge whether all possible loads are normal or not. Depending on the model, the inspection for a specific load can be omitted.

Hereinafter, for convenience of explanation, the respective loads will be described with reference to the washing machine shown in Fig.

The load 50 in this embodiment is hardware that receives and operates electrical energy through the control signal of the control unit 10. [ Therefore, a physical change is generated in the clothes processing apparatus 100 according to the operation of the load 50. [

The main motor 51 may be a unit for driving the drum in which the clothes are accommodated. That is, the control unit 10 controls the drum to rotate. Washing, rinsing, dewatering, drying, and so on.

The cold water valve 52, the condensate valve 53, the bleach valve 54 and the avalve valve 55 may be solenoid valves and on / off is performed through the control signal of the controller 10 They can be called subordinates.

The cold water valve 52 may be a unit for allowing cold water (which may be referred to as tap water at room temperature) from an external cold water supply source to flow into the clothes processing apparatus 100. In particular, the valve may be opened to allow cold water to flow into the tub for washing. Generally, when the cold water valve 52 is opened, the cold water may flow into the tub after passing through the detergent box. Here, the tub is configured to store wash water, and the drum is rotatably provided in the tub.

The condensate valve 53 may be a unit for supplying cold water (cooling water) to remove moisture in the air during drying. Likewise, when the condensate valve 53 is opened, cold water is supplied to the clothes processing apparatus to condense moisture in the humidifier. Therefore, it can be said that the humidifier is converted into dry air.

The bleach valve 54 and the avalanche valve 55 may have similar functions as the cold water valve 52. That is, it may be a valve for introducing cold water into a bleach box and an avalanche box. The valves 54 and 55 may be omitted if necessary, or may be provided to allow bleach and a detergent to be introduced into the drum or the tub at an appropriate time in a clothes processing apparatus in which a bleaching agent and a detergent box are separately provided.

The steam valve 56 may be provided in the clothes processing apparatus 100 provided with the steam function. Likewise, it can be said that the cold water is opened to generate steam. When the steam valve 56 is opened, cold water can be supplied to the steam generator. Of course, the steam valve 56 may be included in a case where the steam generator is provided separately from the tub.

The cold water valve 52, the condensate valve 53, the bleach valve 54, the avalanche valve 55 and the steam valve 56 may all be operated to supply cold water to the clothes processing apparatus. Accordingly, when these valves are operated, a physical change in which cold water is supplied to the clothes processing apparatus is generated.

The steam heater 57 refers to a heater that generates water by heating water in the steam generator. Accordingly, when the steam heater 57 is operated, the water is converted into steam and a physical change in which the temperature rises is generated.

The washing water heater 58 may be a heater for heating water supplied in the tub. That is, it may be a unit for heating the washing water for washing. Therefore, when the washing water heater 57 is operated, the water is heated and a physical change in which the temperature rises is generated.

The drain pump 59 may be a unit for discharging the washing water in the tub to the outside of the clothes processing apparatus 100. When the drain pump 59 is operated, the wash water in the tub is physically discharged to the outside.

The fan motor 62 is a load for generating a flow of air, and the drying heater 63 may be a heater for heating the air. Thus, with the arrangements necessary for drying, their operation will cause a physical change in air circulation and rise in air temperature.

Generally, the garment processing apparatus 100 can perform various courses for garment processing. A course input unit 22 may be provided to select such a course. In addition, an option input unit 24 for changing various conditions can be provided in a specific course. If the course input unit 22 and the option input unit 24 are selected differently, all of the loads described above may be operated, and the specific loads may not be operated.

For example, when only a general washing course is selected, the washing course can be performed using only cold water and terminated. At this time, among the loads shown in Fig. 1, the main motor 51, the cold water valve 52 and the drain pump 59 are operated, and other loads may not be operated.

For example, when the bleach option, the avalanche option, the steam option, the hot water option, the drying option, and the like are all input together with the specific laundry course, the loads shown in FIG. 1 are all operated to end the selected laundry course will be.

On the other hand, the clothes processing apparatus 100 may include various sensors 70. The sensor 70 may include a wide variety of sensors such as a water level sensor, a temperature sensor, a vibration sensor, a hall sensor, and the like. Through sensing and feedback of these sensors, it can be judged whether or not the various loads are operating normally. Of course, through the sensing and feedback of these sensors, the garment processing course is performed according to the set conditions.

Specifically, the sensor 70 may be configured to control the operation of the various loads 50 by sensing the height of the water, the temperature difference, the displacement, the change of the magnetic force, and the like. That is, it may be configured to detect a physical change due to the operation of the load 50. Therefore, in the present embodiment, configurations that cause physical changes by operation are referred to as a load 50, and configurations that detect a physical change caused by their operation may be referred to as a sensor 70. [

The loads 50 are driven through electrical energy, and the normal state of the load itself can be electrically inspected. However, although the load 50 itself is normal, the load 50 may not be normally operated due to an installation error, and the garment processing apparatus itself may not operate normally.

For example, the cold water valve 53 may be controlled to be opened at an appropriate time through the control of the control unit 10. [ Even if the cold water valve 53 is normally opened, the cold water may not normally enter the clothes processing apparatus 100. That is, when the problem of the external water source itself or the faucet of the external water source is locked, the normal cold water supply is not performed even though the cold water valve 53 is normal. In this case, if a change in the water level is not detected through the water level sensor, the garment treating apparatus can detect an abnormality and stop the entire operation of the garment treating apparatus. Thus, a specific load can be detected anomaly while the clothes processing apparatus is being used.

However, as shown in Fig. 1, it is not easy to judge whether or not each of the loads is operating normally, because the frequency with which a very wide variety of loads are all used by a single clothes processing apparatus operation is very small. In addition, it is not easy to determine the problem due to installation errors even though it is operating normally.

In order to solve such a problem, as will be described later, according to the embodiment of the present invention, a clothes processing apparatus and a control method thereof which can perform installation inspection course can be provided.

Meanwhile, as shown in FIG. 1, the user input unit 20 may be provided in the present embodiment, and the user can perform desired clothing processing by operating the user input unit 20.

Specifically, the user input unit 20 may include a power input unit 21. For use of the clothes processing apparatus, the user can select the power input unit 21 and apply power to the clothes processing apparatus. The control unit 10 can automatically control the power source to be released when the garment processing is completed.

After the user selects the power input unit 21, the user can select a desired clothing processing course. That is, a plurality of courses can be provided, and the user can select a desired specific course through the course input unit 22. [

Meanwhile, various options can be selected in the course. For example, various options may be selected depending on the model, such as the temperature of the wash water, the RPM of the drum, the number of rinses, whether the steam option is used, and whether the drying option is used. That is, the user can select a course through the course input unit 22 and select various options in the course through the option input unit 24. [

When the selection of this user is finished, the user can select the start / pause input section 23 so that the clothes processing apparatus substantially starts performing the course. Thereafter, the clothes processing apparatus performs an operation according to a predetermined flow according to the user's selection, and then ends.

In this embodiment, the display 30 may be included. The display 30 may be provided to display various information such as an operation state of the current clothes processing apparatus, a selection item of the user, and the like. Time information on the execution time or remaining time of the course may also be displayed on the display 30.

A large amount of information is recently processed in the display 30 so that the display control unit 12 for controlling the display 30 and the main control unit 11 for controlling the various loads 50 are separately provided. That is, the control unit 10 may include a main control unit 11 and a display control unit 12. Therefore, it is possible to prevent the main control unit 11 and the display control unit 12 from being overloaded.

In this embodiment, a communication module for wireless communication with an external terminal may be included. As an example of such a communication module, an NFC module 40 may be provided. The NFC module 40 may be controlled by the display controller 12. [

Recently, external terminals equipped with NFC modules are widely used. These NFC modules are basically installed in external terminals such as smart phones. Thus, various information can be exchanged between the smartphone and the garment processing apparatus by executing the application of the smart phone.

Communication through this NFC module can be used to extend the physical limitations of the user input 20. In addition, communication via this NFC module may be used to extend the performance limit of the display 30. [ Details thereof will be described later.

Hereinafter, the control flow of the clothes processing apparatus according to the present embodiment will be described in detail with reference to Fig.

When the clothes processing apparatus is installed for the first time, the user or the installer basically selects the power input unit 21 to apply power to the clothes processing apparatus 100. That is, the clothes processing apparatus 100 performs step S100 of applying power by the input of the power input unit 21. [

In general, the user or the installer does not separately take measures for the normal operation of the clothes processing apparatus and for the installation inspection when such power input is performed. That is, it is common to only perform visual actions to the extent that the product is properly installed.

When the power is applied, the user can sequentially select the course input unit 22 and the start / pause input unit 23 to operate the garment processing apparatus to process the garment. That is, although there is an exception, the course selection through the course input unit 22 is the highest priority user selection.

However, in the present embodiment, the installation inspection course can be input in the initial state after the power is applied. That is, step S200 may be performed in which the installation inspection course is input in priority to the input of the course input unit 22.

The installation inspection course is a course for checking whether or not the clothes processing apparatus is normally installed, unlike a general clothing processing course. In addition, the installation inspection course can be a course for checking whether a plurality of loads are operating normally. Therefore, it is preferable that the installation inspection course is executed when the clothes processing apparatus is installed for the first time. Of course, the installation inspection course can be executed even after the product is repaired. That is, the frequency of execution of the installation inspection course is very low. For this reason, it is not preferable to select the installation inspection course through the course selection unit 22. [

According to the present embodiment, it is preferable to be able to input the installation inspection course through a separate input unit or means other than the course selection unit. For example, an installation inspection course can be entered via a hidden button.

Specifically, according to the present embodiment, an installation inspection course may be input (S200) through NFC tagging corresponding to a request to start installation inspection course from an external terminal. That is, after the power is applied, the installer can input an external terminal equipped with the NFC module to the NFC module of the garment processing apparatus to perform the installation inspection course. Of course, it is preferable that an appropriate application is installed in the external terminal so that such a request can be performed.

On the other hand, other selections such as selection of the course selector after power is applied can be preceded. At this time, NFC tagging for requesting installation inspection course may be performed. NFC tagging can also be performed during the course of a typical garment processing course. At this time, the apparel processing apparatus 100 is informed that it is not a normal request. For example, a buzzer may sound to inform the user that the input is abnormal.

When a normal installation inspection course input is generated in the initial state after power is applied, that is, when all the loads are off, the garment processing apparatus performs the installation inspection course (S300). That is, all loads are operated to check whether all the loads are normal, and whether or not the clothes processing apparatus is normally installed. Specific installation inspection courses will be described later.

When the installation inspection course is completed, step S400 of notifying the user of the inspection result is preferably performed. That is, the test result can be informed to the user through various methods such as voice, text, and graphics. For example, the test result may be displayed on the display 30, or the test result may be transmitted to the external terminal.

When the installation inspection course is completed, the clothes processing apparatus can be automatically released after a predetermined time has elapsed. First, when the installation inspection course is completed, a buzzer may sound to indicate completion. The power can be automatically released after a lapse of a predetermined time (for example, 5 seconds) after the buzzer sounds.

NFC tagging can be performed within this preset period. That is, the external terminal can be tagged to the NFC module. When such tagging occurs, the apparel processing apparatus can transmit the inspection result to the external terminal. When the transmission of the inspection result is completed, the power of the clothes processing apparatus can be released. The installation inspection course may be substantially terminated (S500) by releasing the power supply.

These test results indicate whether the various loads are operating normally and whether the clothes handling unit is properly installed. Details of this will also be described later.

FIG. 3 shows a concrete flow of the installation inspection course execution (S300) shown in FIG.

First, when the normal installation inspection course input (S200) is performed, the installation inspection course is started (S301). The start of the installation inspection course is started when the driving of all the loads to be inspected is stopped, that is, in the off state. In addition, it is preferable that a subsequent inspection step is performed in a state in which all loads are stopped after the specific inspection step described later is completed.

When the clothes processing apparatus is a washing machine, it is preferable to perform the main motor checking step (S302) first. That is, a step of checking whether the motor driving the drum is abnormal, whether it is in normal operation, or the like is performed.

It is preferable to operate the drain pump 59 before driving the drum. This is because there is room for the washing water to remain in the tub during the inspection for product launch, and the residual of the washing water may affect the inspection step for other loads. For example, it may affect the load of the motor, vibration, sensing the water level in the tub, and the like.

Therefore, the drain pump 59 is driven until the predetermined level is sensed. Here, the predetermined water level is the water level corresponding to the full drainage, and the water level can be sensed according to the kind of the water level sensor in Khz unit.

Basically, when it is sensed that the predetermined level is not reached by the operation of the drain pump 59 within a predetermined time (for example, 60 seconds), it can be judged that a problem has occurred in the basic drainage of the washing machine. Therefore, in this case, it is preferable to end the installation inspection course without performing all subsequent inspection steps.

The installer or service technician will be able to identify the drainage related anomaly or anomaly early and take appropriate action. For example, the drain hose can be connected properly. After this action, the installation inspection course can be re-run.

When there is no abnormality related to the drain pump 59, the main motor can be controlled to be driven. The target RPM of the main motor can be controlled in multiple stages. The target RPM is controlled by the first RPM (for example, 108 RMP) in the vicinity of the resonant RPM, and the time to reach the first RMP is checked. Then, the maximum UB value (vibration amount) in the first RPM is measured. Then, the target RMP is controlled to the second RMP (for example, 1000 RMP) which is the dehydration RPM, and the time to reach the second RMP is checked.

Through the motor checking step S302, whether or not the drain pump is abnormal, the UB value, the abnormality of the motor, the first RMP non-arrival or the second RMP non-arrival can be checked.

The motor inspection step S302 may store the result values and terminate the next inspection step. However, as described above, in the case of the drain pump 59 or more, no further inspection steps are performed.

If the UB value appears largely through the motor inspecting step S302, it is possible to grasp the horizontal problem of the clothes processing apparatus, the problem of non-separation of the stud bolt (that is, the sealing bolt) have. In addition, each of the causes of unreachability to target RMPs can be grasped. Therefore, the installer or the service engineer can perform proper repairing of the product or normal installation of the product through the result of such motor inspection step.

When the motor inspection step S302 is completed, it is preferable that steps S310 to check whether abnormality or normal installation of a valve or the like associated with the external cold water source is performed are performed. That is, it is checked whether there is an abnormality or a normal installation of the structures for allowing the cold water to flow into the clothes processing apparatus from the external cold water source after the drainage is normally performed.

A plurality of such configurations may be provided and may be omitted or added depending on the model or the product. However, this configuration is the same in that when the valve is opened, cold water is supplied from the external cold water source to the clothes processing apparatus. And the order between them can be changed.

First, the cold water valve inspection step S311 may be performed. The cold water valve S52 is a valve for supplying cold water to the turbine from an external cold water source. It is possible to drive the cold water valve S52 for the preset time and to sense the water level in the tub after the water level stabilization. Then, the temperature before the water supply can be sensed. Therefore, when this step ends, the water level change and the tub temperature value before the water supply can be stored.

Here, when the water level change occurs, it can be understood that the cold water valve S52 operates normally. Of course, this is the case when the rise in water level is sensed.

When the cold water valve inspection step S311 is completed, the condensate valve inspection step S312, the bleacher valve inspection step S313 and the avalanche valve inspection step S314 can be sequentially performed. These condensate valves, bleach valves and avalve valves can be omitted or added depending on the model. Thus, the model check can be performed at the beginning of the inspection step, and if the model does not include such a configuration, the inspection step can be omitted.

Here, the cold water valve, the condensate water valve, the bleach valve, and the avalve valve may be referred to as valves for supplying cold water to the inside of the tub connected to the external cold water supply source. Therefore, when these valves operate normally, the water level in the tub rises. Therefore, it is checked whether the water level rises in each inspection step. If a rise in water level is checked, at least these valves can be judged to be operating normally.

However, during installation, these valves may be connected to an external hot water source other than the external cold water source. Therefore, in the last inspection step among the inspection steps for these valves, in this embodiment, the tub temperature after water supply is sensed in the avalve valve inspection step (S314).

That is, in the first inspection step for the valves supplying the cold water to the turbine, the temperature after the feed water is sensed in the last inspection step for the valves before and after the water supply. Then, the pre-feed temperature and post-feed temperature can be compared. If the temperature difference is not large, it can be judged that the external cold water source is normally connected. However, if the difference in temperature is large, it can be judged that it is connected to the external hot water source instead of the external water source. That is, it can be judged that the installation is abnormal.

Comparing the temperatures through the plurality of steps sufficiently reflects the characteristics of the hot water source. This is because it is difficult to immediately supply hot water of the desired temperature range. Therefore, it can be judged that the external water source is properly connected with sufficient time.

In addition, the time required for the inspection steps can be reduced because the water supply is performed through several valves. That is, since the water level sensing and re-watering by one water supply can reduce the time for separately calculating the drainage and water level standards.

Therefore, by sequentially performing the inspection steps for the valves for supplying the cold water to the turbine, the total execution time for the installation inspection course can be remarkably reduced. Of course, the inspection reliability can be further increased.

On the other hand, a steam valve S56 may be included as a valve for supplying cold water to the clothes processing apparatus. Similarly, in a model in which a steam generator is excluded, this inspection step may be omitted. It is preferable that the steam valve is performed after the completion of the inspection step of all the valves for supplying the cold water with the turbine.

When the steam generator is provided in the form of a container, the water level inside the steam generator may be sensed and the abnormality of the steam valve S56 may be inspected. If the steam generator is provided in the form of a tube, the water level in the tub may be sensed and the abnormality of the steam valve may be inspected.

When the inspection step of the steam valve S56 is completed, the step of inspecting the steam heater S320 is preferably performed. It is possible to judge whether or not the steam heater is normal by comparing the temperature before and after the operation of the steam heater. Of course, if no steam generator is provided, this step may be omitted. It is preferable that the inspection steps of the steam valve and the steam heater are performed sequentially. This is because it is possible to prevent overheating of the heater and reduce the inspection time required by sequentially performing heating after the water supply.

On the other hand, when the inspection step of the valves associated with the cold water and the inspection step associated with steam, if necessary, are completed, the washing water heater inspection step S330 is preferably performed. Cold water is supplied to the inside of the tub before this inspection step is performed. Therefore, even if the washing water heater is driven immediately, the problem of overheating does not occur. In addition, the time required for additional water supply can be reduced. Of course, additional water supply may be needed if the water level is sensed below the minimum water level for heating (the water level sensed at the nearest previous point in the present step). However, if the previously sensed water level is above the minimum water level, no additional water level sensing or additional watering need be performed. Therefore, the time required for the installation inspection course can be significantly reduced.

In this step, the water temperature in the tub before and after heating can be compared. Therefore, it is possible to easily grasp whether or not the washing water heater is operating normally.

Thereafter, the drain pump inspection step S340 may be performed. When performing this step, the water level in the tub is at a relatively high water level. Therefore, it is possible to check whether the drain pump is normal by performing drainage stepwise. In the main motor inspection step S302, it can be said whether the drain pump is capable of performing a substantially complete drainage, and in this inspection step, it is practically examined whether the drainage pump operates normally over the entire operation water level range can do.

When the drain pump inspection step S340 is completed, it is preferable that the inspection step S350 for the hot water valve 60 is performed. That is, it is preferable to perform the inspection step for the hot water valve 60 after draining all the washing water associated with the cold water. The hot water valve 60 may be a valve that allows hot water to flow into the clothes processing apparatus from an external hot water source.

First, it is possible to determine whether the operation of the hot water valve 60 itself is abnormal through the change of the water level by the water supply. The difference between the temperature in the tub before the water supply and the temperature in the tub after the water supply can check whether or not the water is properly connected to the external hot water source. For example, if there is no difference in temperature, it can be judged that it is once connected to the external cold water source. However, it can be considered in combination with the above-described determination result in the cold water valve or the like. This is because, for example, if both valves are functioning normally and the result is that there is no temperature change, it may be a problem of the external hot water source itself. That is, it may be judged that there is a problem such as a boiler abnormality or a valve closure of an external water source. Therefore, it is possible to check not only the connection error of the connection hose but also whether the external water supply sources are normal or not.

Thereafter, if necessary, the circulation pump inspection step S360, the fan motor, and the drying heater inspection step S370 may be performed.

The circulation pump test is a process of judging whether the pump operates normally by changing the water level by driving the circulation pump.

Fan motor and dry heater inspection are provided in a washing machine that provides a drying function, so this step may be omitted if the model does not have this function.

In this step, it is preferable that a multiple is performed first. Then, the fan motor is driven to check whether the fan motor normally reaches the Mokpo RMP. When the fan motor is driven normally, it is possible to check whether the temperature rises by driving the dry heater. Therefore, it is possible to check whether the fan motor and the dry heater operate normally or not through this step.

When the inspection steps are sequentially performed and terminated, all the loads are turned off (S380), and the inspection steps are terminated. Thereafter, as shown in FIG. 2, the result notification step S400 is performed, and the installation inspection course is finally terminated (S500).

In the above-described steps, all the loads are directly driven to check whether there is a physical change. Therefore, it is possible to grasp not only whether each load itself is normal, but also whether it is normally installed during the installation process.

This installation inspection course is started and terminated sequentially as in the case of a general laundry course, and it is possible to check whether or not the normal operation is practically performed for each of the loads. In addition, it is possible to grasp whether the entire clothes processing apparatus is normal or not in a relatively short time by organically performing inspection steps for each load.

From the user (consumer) point of view, after purchasing and installing the product, it is possible to visually confirm that the product is normally installed, while checking details of the product abnormality. Therefore, the reliability of the product itself and installation can be increased.

The reliability of the product itself and the reliability of the service can be increased in terms of the provider (seller) including the installer and the service article. In addition, it is possible to prevent unnecessary follow-up action due to the problem of the installation process not the abnormality of the product itself.

Therefore, through the apparel processing apparatus and its control method to which the installation inspection course is applied, the satisfaction of the user can be improved and the reliability of the provider can be ensured.
