Description

Method for Recover an Error of Control Module of Multi-Function Storage System}

The present invention is a control module error recovery method of a multi-functional storage system, more specifically, using two microcomputers, a first control module and a second control module, and when an error occurs in each of these, an algorithm for performing recovery It relates to a control module error recovery method of a multi-functional storage system that improves the stability of the system by configuring differently from each other.

Recently, as fine dust concentrations have deteriorated, interest in the treatment and management of clothes, shoes, and blankets, which may adhere to various pollutants floating outdoors and indoors, as well as air quality in indoor spaces is increasing. Accordingly, devices for removing pollutants and managing clothes, shoes, and blankets are being developed, and demand for devices having various functions related thereto is increasing.

In general, the clothes management apparatus is configured to clean clothes through dusting, humidification, dehumidification and finishing processes. These dusting, humidification, dehumidification and finishing steps are controlled by a microcomputer (hereinafter referred to as'microcomputer') provided in the clothes management device, and more specifically, a blower fan provided in the machine room of the clothes management device, and heat. It is configured to clean clothes by controlling electronic devices such as a pump module by the microcomputer.

A microprocessor is a microprocessor composed of one or several large-scale integrated circuits (LSIs) of the computer's operation processing unit, and a microcomputer that is mounted on a board with a memory device and an interface circuit with peripheral devices attached thereto. It is possible to control various devices that receive control signals and electric signals and drive them by receiving electric signals. Such a microcomputer may store a plurality of algorithms and various data to directly control an electronic product, and is provided to generate a control signal by processing a specific input signal whenever it is received.

For example, a microcomputer provided in a clothing management device cleans clothing by outputting a signal to control a blower fan, a heat pump module, etc. by calculating a stored algorithm or data when a command to operate the clothing management device is input. You will perform the overall administration.

Meanwhile, the microcomputer may malfunction due to various causes, such as an operation error, noise, input of an incorrect signal, etc. that may occur during a repetitive operation process. For example, the microcomputer may not receive external signals or respond to external signals due to surging such as system down, causing a runaway phenomenon that generates an output signal completely different from the intended signal. You may fall into a malfunctioning state of the device. Accordingly, when a malfunction occurs in the micom, the electronic device in which the micom is installed and various devices including the same cannot be normally controlled or operated, and thus it is necessary to detect and correct it.

Korean Patent Laid-Open Publication No. 1997-0071209 is disclosed as a prior art for checking and recovering the malfunction of the microcomputer. The prior art discloses a control device that includes an external watchdog timer unit as a'microcomputer operation monitoring control device' and automatically initializes the microcomputer when the microcomputer recovers from normal operation. However, since the prior art is a configuration using a single microcomputer, there is no means to replace the microcomputer when a malfunction occurs, and thus there is a very low problem in terms of maintaining the stability of the system.

Accordingly, in recent years, there is a need for a technology that improves the stability of the system by controlling the laundry treatment device using a plurality of micoms, and enables the laundry treatment device to operate normally even when a specific micom malfunction occurs. .

In addition,'course' used below is a higher concept of'mode'. For example,'clothing management course' includes'pre-treatment mode','humidification mode','dehumidification mode', and'post-treatment mode' in time series. It is a connected concept. The user can select'Course' and only'Mode'.

1. Description of the structure of the multifunctional storage system

1 to 3, the multifunctional storage system according to the present invention includes a storage room 100, a machine room 200, a recirculation module 300, a memory unit 410, and control modules 401 and 402.

The storage room 100 is a space in which clothes, etc. are accommodated to remove pollutants or odor substances. To this end, after the interior of the storage chamber 100 rises to a high temperature, natural humidified air may be introduced and circulated as circulating air. Inside the storage chamber 100, a circulation filter detachable part (not shown), a circulation air inlet, and a circulation air outlet are located on the lower surface. The circulation filter detachable part is an opening provided to easily detach and detach the circulation filter unit 229 located in the machine room 200 for repair or replacement.

The circulating air inlet (not shown) and the circulating air outlet (not shown) are openings through which circulating air inside the storage chamber 100 flows in and out of the machine room 200, respectively. The circulating air inlet is communicated with the fan unit 230 so that air is discharged from the machine room 200 to the storage room 100, and the circulating air outlet is configured to allow air to flow from the storage room 100 to the machine room 200. It is formed to be circulated. In addition, the portion in communication with the circulating air inlet in the storage chamber 100 is formed to be inclined upward, so that the air introduced from the circulating air inlet is at a predetermined angle upward from the bottom surface of the storage chamber 100. And is formed to be discharged into the storage chamber 100 (meaning that it is discharged obliquely, not in a vertical direction). Accordingly, cleaning efficiency can be increased by contacting clothes stored in the storage chamber 100 with a larger area than when the circulating air discharged from the circulating air inlet is in a vertical direction.

The machine room 200 is a space that circulates air by introducing and filtering air from the storage room 100 in the'clothing management course' and then outflowing natural humidified air as circulating air. The machine room 200 includes an intake port 210, a first channel 220, a fan unit 230, a second channel 240, an exhaust port 250, a dehumidifying unit 260, a supply tank 270, and a condensate tank ( 280).

The intake port 210 is a part that sucks outside air into the machine room 200. The exhaust port 250 is a part that receives the filtered outside air from the second flow path 240 and discharges it to the outside. It can be open or closed depending on your choice. A clean filter unit detachment part (not shown) is located in the intake port 210 so that the clean filter unit 219 may be located. The clean filter unit 219 functions to filter outside air sucked in the'air clean mode', which is another course of the multifunctional storage system, and may include a pre-filter, a HEPA filter, etc., but is not limited thereto.

The first flow path 220 communicates with the intake port 210, the second flow path 240, and the fan unit 230. A circulation filter unit 229 is located inside the first flow path 220. The circulation filter unit 229 may function to filter circulating air. The circulation filter unit 229 may include a humidification filter, so when the water stored in the supply water tank 270 is supplied to the humidification filter, moisture is supplied during the passage of the circulation air to form natural humidified air. The user can remove or install the circulation filter unit 229 by opening a door (not shown) and accessing the circulation filter detachment unit (not shown).

By the operation of the fan unit 230, the air inside the storage chamber 100 flows into the second flow path 240 through the circulating air outlet 142, and flows back into the first flow path 220, so that the fan unit 230 ). In this process, air passes through the humidification filter of the circulation filter unit 229 to become natural humidified air. It passes through the second flow path 240 again and is supplied to the storage chamber 100 through the circulating air inlet. As this process is repeated, circulating air continuously circulates between the storage room 100 and the machine room 200. The circulating air contains pollutants or odorous substances in the storage chamber 100, but since they are not discharged to the outside, a comfortable environment is provided to the user.

The second flow path 240 receives filtered outside air or circulating air from the fan unit 230. The second flow path 240 is selectively communicated with any one of the storage chamber 100 and the exhaust port 250, and It includes a first flow path switching member 241 and a second flow path switching member 242 for control. The first flow path conversion member 241 and the second flow path conversion member 242 are paired and operated to change the flow path. In one embodiment, the first flow path conversion member 241 and the second flow path conversion member 242 may be members that rotate about an axis, but any mechanism for selectively changing the flow path may be adopted.

The dehumidifying unit 260 performs a function of dehumidifying circulating air flowing through the storage chamber 100. The dehumidifying unit 260 may be, for example, a heat pump, but is not limited thereto. Heat may be generated while the dehumidifying unit 260 performs dehumidification, but such heat is not wasted and may be used in clothing management. For example, after the storage chamber 100 is heated to about 50 to 70 degrees Celsius using heat generated during the dehumidification process by the dehumidifying unit 260, the room temperature is circulated from the second flow path 240 through the circulating air inlet. By receiving air, contaminants such as clothing or odorous substances can be removed. For another example, as described above, heat generated in the process of dehumidifying by the dehumidifying unit 260 is supplied to the humidifying filter of the circulation filter unit 229 or to the tubing connecting the supply water tank 270 and the humidifying filter. Provided, it is also possible to heat natural humidified air that functions as circulating air. It goes without saying that the above-described temperature is an example, and is not limited thereto and may be variously changed. In addition, only one of the dehumidifying unit 260 and the circulation filter unit 229 (ie, a humidifying filter) may be selectively operated so as not to interfere with each other.

The supply water tank 270 stores water to be supplied to the humidification filter provided in the circulation filter unit 229. To this end, it is connected to the circulation filter unit 229 through tubing. The condensed water tank 280 collects and stores the condensed water generated in the storage room 100, or the saturated humid air generated in the storage room 100 is the first flow path 220 or the second flow path 240 of the machine room 200 It collects and stores condensed water generated in the process of flowing into and condensing. To this end, the storage chamber 100 and/or the first flow path 220 and/or the second flow path 220 are connected by tubing. In order to fill with water or discard the filled condensate, it is preferable that the user can easily access both the supply water tank 270 and the condensate water tank 280.

The machine room 200 may be located in any direction with respect to the storage room 100, but it is preferable to be located under the storage room 100. This is because the condensed water or saturated humidified air condensed in the storage room 100 can be introduced into the machine room 200 by its own weight, and thus can be discharged to the outside through the condensed water tank 280.

The recirculation module 300 helps circulation of the circulating air. Since the recirculation module 300 recirculates the circulating air from the upper side of the storage room 100, the convection phenomenon is made more smoothly throughout the storage room 100. In addition, by operating independently of whether or not the machine room 200 is operated, it may be operated to remove contaminants such as clothes stored in the storage room 100. 1 to 3 are shown on the basis of the state in which the recirculation module 300 is provided, but it goes without saying that the recirculation module 300 may not be provided. In addition, even if the recirculation module 300 is provided, the recirculation module 300 does not operate when the fan unit 230 is operated, and may be formed to operate independently.

The memory unit 410 is a space for storing information on a multifunctional storage system. The memory unit 410 may include an EEP-ROM (Electronically Erasable and Programmable Read Only Memory), but is not limited thereto as long as it is a type capable of storing a memory. In the EEP-ROM, information may be written and deleted by the control modules 410 and 402. The EEP-ROM may be composed of a non-volatile memory in which information stored therein is not erased and maintained even when power supply is stopped due to power off. In the following description, the memory unit 410 and the control modules 401 and 402 have been described as separate configurations, but this refers to functional separation, not physical separation. The memory unit 410 and the control modules 401 and 402 may be integrally formed according to the implemented system and device.

The first control module 401 is a module electrically connected to the operation unit 610. When the user selects a desired course or mode and inputs it to the operation unit 610, the first control module 401 is configured to transmit an operation signal to the second control module 402. As shown in FIG. 1, the operation unit 610 is provided on the outer surface of the door unit 600 to provide convenience to the user's input operation. In addition, in order to visually inform the user of information on the state of the multifunctional storage system currently in operation, a display panel is provided, and the display panel may be formed to enable user input through a touch method.

The second control module 402 is a module that electrically controls components located in the machine room 200. The second control module 402, which has received the operation signal from the first control module 401, operates them by electrically transmitting a command signal to the components in the machine room 200. For example, when the user selects the clothing management course, this means that the selection of the clothing management course is input to the first control module 401, and the second control module 402 It receives operation signals for time-series execution of the pre-processing mode, humidifying mode, dehumidifying mode and post-processing mode constituting the management course, and controlling the operation of components corresponding to each mode.

Meanwhile, since the first control module 401 and the memory unit 410 are provided on the side of the storage room 100, electronic interference of components in the machine room 200 may be prevented. The second control module may be provided in the machine room 200.

2. Description of the machine room mode of the multifunctional storage system

(1) Clothing management course description

Step S100 is a step in which a'clothing management course' is performed.

The machine room 200 may perform a pre-treatment mode, a humidification mode, a dehumidification mode, and a post-treatment mode, which are detailed processes constituting the clothing management course. Hereinafter, the clothes management course is largely divided into a pre-treatment mode, a humidification mode, a dehumidification mode, and a post-treatment mode, but an additional mode related to cleaning of clothes may be added. Meanwhile, the machine room 200 may be operated so that the operation of the clothing management course is performed in the order of a pre-treatment mode, a humidification mode, a dehumidification mode, and a post-treatment mode, but the pre-treatment mode and the post-treatment mode are partially or completely It is structured so that it can be omitted.

1) Description of humidification mode

The operation of the components of the machine room 200 in the humidification mode will be described with reference to FIG. 2.

In the humidification mode, the air sucked by the fan unit 230 passes through the circulation filter unit 229 and is formed as natural humidified air. In order to circulate the natural humidified air into the storage chamber 100, the circulating air inlet and the circulating air outlet are opened. Here, a humidification filter is provided in the circulation filter unit 229, water is supplied to the humidification filter of the circulation filter unit 229 from the supply water tank 270, and to the supply water tank 270 using a supply pump (not shown). It can be formed so that the stored water is forcibly supplied.

In the humidification mode, natural humidified air is circulated to the storage room 100 to create a humid environment inside the storage room 100. Accordingly, humidification may be applied to the clothes stored in the storage room 100. The air particles contained in the natural humidified air are combined with the pollutant particles and odor particles embedded in the clothing, and the pollutant particles and odor particles are removed from the clothing together in the process of dehumidifying the clothing during the dehumidification mode operation described later.

Meanwhile, in FIG. 2, the fan unit 230 has been described based on the suction fan, but may be formed of a discharge fan, and in this case, the arrangement of components inside the machine room 200 may be rearranged to suit the discharge fan.

2) In dehumidification mode operation

The operation of the components of the machine room 200 in the dehumidification mode will be described with reference to FIG. 3.

In the dehumidification mode, the dehumidifying unit 260 inside the machine room 200 operates, thereby dehumidifying the circulating air flowing through the storage room 100. For dehumidification of the storage room 100, the fan unit 230 is operated to circulate dry air, and the circulating air inlet and the circulating air outlet 142 are opened. Condensed water generated during the dehumidification mode operation may be stored in the condensate water tank 280. By performing the dehumidification mode, contaminant particles and odorant particles adhering to the clothing can be removed from the clothing.

3) In pre-processing mode and post-processing mode operation

The operation of the components of the machine room 200 in the pre-processing mode and the post-processing mode will be described with reference to FIG. 3.

The pretreatment mode is the starting stage of the clothing management course, and plays a role of primarily removing dust or contaminants having a relatively large particle size adhered to cloth by discharging air. The pretreatment mode is also referred to as the'air shower mode' and refers to the process of strongly spraying air. Prior to removing contaminants from the clothes inside the storage room 100 in earnest, the contaminants may be shaken off in advance to increase the cleaning efficiency of the clothes. In the pretreatment mode, the circulation filter unit 229 and the dehumidification unit 260 do not operate, and only the fan unit 230 is configured to operate.

The post-treatment mode is a finishing step of the clothing management course, by supplying air through the fan unit 230 to remove foreign substances that may remain in the clothing once more and to redry the interior of the storage room 100. Play a role. The post-processing mode is also referred to as'air smoothing mode'. The operation of the components of the machine room 200 in the pre-processing mode and the post-processing mode is the same, but the output of the fan unit 230 may be controlled differently. For example, the output of the fan unit 230 in the pre-processing mode may be formed to be relatively larger than the output of the fan unit 230 in the post-processing mode.

On the other hand, in the present specification, between the pre-treatment mode and the post-treatment mode, the humidification mode and the dehumidification mode are described, but the humidification mode and the dehumidification mode may be repeatedly performed a plurality of times, and the user may use the storage compartment 100 The number of times the humidification mode and the dehumidification mode are performed can be adjusted according to the type of clothing stored in the device or the type of fabric.

In addition, in the pre-treatment mode and the post-treatment mode, both the storage room 100 and the machine room 200 are in communication with each other, but are preferably performed in a state in which the outside air is blocked. In particular, when performing the pretreatment mode, if the machine room 200 is not blocked from outside air, foreign matter particles inside the storage room 100 may be discharged to the outside of the multifunctional storage system. This is because it can be reduced. Even in the post-processing mode, in order to block the influence on the humidity and temperature of the space in which the multifunctional storage system is located, it is preferable that the machine room 200 is operated in a state where the outside air is blocked.

(2) Description of air cleaning mode

The operation of the components of the machine room 200 in the air cleaning mode will be described with reference to FIG. 4.

The air cleaning mode is a mode in which only the machine room 200 is operated independently from the storage room 100 to perform a function of purifying the outside air. That is, since clean clothes, etc. may be located inside the storage room 100 while the outside air is contaminated, it is an operation mode in which outside air does not flow into the storage room 100.

When the user selects the air cleaning mode, the exhaust door 650 of the door 600 is opened and the intake port 210 is also opened.

The first flow path conversion member 241 and the second flow path conversion member 242 of the machine room 200 operate to communicate the second flow path 240 with the exhaust port 250, and the storage room 100 and the first flow path 220 Block from ). In this process, the storage room 100 becomes an independent space from the machine room 200.

The fan unit 230 operates. With the operation of the fan unit 230, outside air is introduced into the first flow path 220 through the intake port 210 and is directed toward the fan unit 230. In the process of passing through the intake port 210, outside air is filtered by the clean filter unit 219 located in the intake port 210. In the process of passing through the first flow path 220, it may be further filtered by the circulation filter unit 229 located in the first flow path 220. In this way, in the process of forcibly circulating air by the fan unit 230, the humidification filter located in the circulation filter unit 229 can be dried. Drying of the humidification filter receiving water from the supply tank 270 at all times. Through this, the proliferation of bacteria in the humidification filter can be prevented, and the problem of generating odor can be solved at once. The filtered outdoor air that has passed through the fan unit 230 passes through the second flow path 240 and is exhausted to the outside through the exhaust port 250.

As this process is repeated, the multifunctional storage system according to the present invention performs a kind of air purifier function. The outside air is continuously introduced into the machine room 200 and filtered, and the filtered air is continuously exhausted.

It is preferable that the air cleaning mode can be performed regardless of whether the user opens the door 600. Even during the air cleaning mode operation, the user can freely open the door 600 to place clothes or the like inside the storage room 100 or take out clothes or the like. At any time, water can be filled in the supply tank 270 and the water in the condensed water tank 280 can be discharged. Since the door 600 does not cover the intake port 210 and the exhaust port 250 is opened from the inside of the door 600, the opening of the door 600 does not affect the air cleaning mode operation.

The user checks only whether the exhaust door 650 is open even at a location far from the multifunctional storage system, that is, a location where the control unit 610 is not clearly visible, and whether the user is currently operating in the air cleaning mode or in the clothing management course. I can confirm.

3. Description of error recovery method of control module of multifunctional storage system

(1) When an error in the first control module is confirmed

When an error in the first control module 401 is confirmed, it will be described with reference to FIGS. 5 and 6 for explanation of a method for recovering the error.

The first control module 401 is configured to be electrically connected to the memory unit 410 to enable communication, and may be configured as a harness connected by wire.

The error recovery method of the first control module 401 includes steps S100 to S124.

Error checking of the first control module 401 may be performed by a watch-dog that is a monitoring means. The watchdog may be configured to check the abnormal state of the first control module at a preset time period, and more preferably, may be configured to check in real time.

Step S100 is a step in which the first control module 401 is initialized, which means reset.

Step S110 is a step in which the first control module 401 loads control information from the memory unit 410. In the above-described operation of the machine room 200, mode information of the machine room 200 may be stored in the memory unit 410 whenever an arbitrary mode is terminated. The first control module 401 may receive information about a currently operating mode and course type and remaining time through the memory unit 410.

Step S120 is a step in which the first control module 401 transmits an operation signal to the second control module 402 by using the control information loaded in step S110, and steps S121 to S124 ).

Specifically, step S121 is a step in which the first control module 401 is restored using the control information. In this process, it may be configured to display the restored control information on the display panel interlocked with the first control module 401.

In step S122, the first control module 401 uses the control information to check whether the machine room 200 is performing a humidification mode or a dehumidification mode. When the machine room 200 performs the humidification mode, since residual moisture is present in the storage room 100 at present, there is a risk of damaging the cloth if not removed. When the machine room 200 performs the dehumidification mode, it means that the dehumidification mode is not completed. In this case, there may also be a problem in that residual moisture is present. That is, in step S122, in connection with the execution of the forced dehumidification mode to be performed later, it is a step of checking whether residual moisture is present in the current storage room 100.

In step S123, when it is confirmed that the machine room 200 is performing the humidification mode or the dehumidification mode in the previous step S122, the first control module 401 is transferred to the second control module 402 in the machine room 200. This is the step of transmitting an operation signal for performing the forced dehumidification mode of ). That is, the current state of the storage room 100 means that residual moisture is present, and that the residual moisture needs to be removed.

Step S124 is a step in which an operation signal for the forced dehumidification mode of the machine room 200 is generated by the second control module 402 to perform the forced dehumidification mode of the machine room 200. Here, the'forced dehumidification mode' may operate in the same manner as the'dehumidification mode' described above, but specific control information such as intensity and time of dehumidification may be formed differently.

In addition, the forced dehumidification mode of the machine room 200 performed in step S124 is formed so that the dehumidification strength or the execution time of the forced dehumidification mode is variable, but the dehumidification strength or the forced dehumidification mode execution time is performed in the humidification mode of the machine room 200 It can be set to depend on time. The humidity of the storage room 100 may be different according to the operation time of the humidification mode. The first control module 401 or the second control module ( By setting it at 402, it can be configured so that it is not necessary to provide an expensive and precise humidity sensor inside the storage room 100.

(2) When an error of the second control module is confirmed

When an error in the second control module 402 is confirmed, it will be described with reference to FIGS. 7 and 8 for explanation of a method for recovering the error.

The second control module 402 is configured to be electrically connected to and communicated with the first control module 401, which may be configured as a harness connected by wire. Further, the first control module 401 and the second control module 402 may each include a communication module (not shown) for wireless communication.

The error recovery method of the second control module 402 includes steps S200 to S232.

Step S200 is a step in which the second control module 402 is initialized, which means reset.

Step S210 is a step in which the second control module 402 requests control information from the first control module 401. Since the second control module 402 is initialized in the step S200, the operation of the configuration of the machine room 200 is also reset for a very short time, for example, several milliseconds (ms), and the second control module 402 ) Requests control information from the first control module 401 to receive control information including a course, a mode, and a remaining time that is currently in progress.

Step S220 is a step in which the second control module 402 receives control information from the first control module 401.

Step S230 is a step of generating an operation signal using the control information received by the second control module 402 in step S220, and specifically includes steps S231 and S232.

In step S231, the second control module 402 checks whether the machine room 200 is operating through control information. That is, it is primarily to check whether the machine room 200 is in operation or in a standby state.

In step S232, when it is determined that the machine room 200 is operating in step S231, an operation signal is generated to continue the operation of the machine room 200. More specifically, the above-described control information includes mode information of the machine room 200, remaining time information of a mode being executed (or execution time information of a mode), and course information in which different modes are combined in a time series. It includes both remaining time information and remaining mode information so as to continue the operation of the machine room 200, and the operation signal means an electrical signal for the remaining time information and the remaining mode information.

Meanwhile, the operation signal in step S232 may further include a compensation operation signal. The compensation operation signal may relatively further increase the humidity strength or increase the humidification time in the humidification mode. In addition, even in the dehumidification mode, the dehumidification strength may be relatively further increased or the humidification time may be further increased. As a modification of the above, it is configured to perform the humidification mode and dehumidification mode by intensively increasing the humidification strength and dehumidification strength for only a preset time, and then return the humidification strength and dehumidification strength to a normal state when the preset time elapses. I can.

(3) In case of communication error between the first control module and the second control module

A communication error between the first control module 401 and the second control module 402 will be described with reference to FIG. 8.

The first control module 401 and the second control module 402 are formed to enable communication using electrical signals, and are configured to communicate with each other in a protocol manner.

At this time, when the second control module 402 requests control information from the first control module 401, the transmission signal of the second control module 402 does not match the protocol of the first control module 401 , The error is recovered by performing steps S310 to S330.

Step S310 is a step of processing the transmission signal of the second control module 402 as an invalid value in the first control module 401. The first control module 401 and the second control module 402 respectively set a range of a transmission/reception protocol value, and if the value is not within the set range, it treats it as an invalid value.

In step S320, the second control module 402 retransmits a transmission signal for re-requesting control information to the first control module 401, but within a range of a preset number, the first control module 401 In this step, the transmission signal is retransmitted until it is processed as a valid value. At this time, the second control module 402 re-requests the control information to the first control module 401 is configured to request a predetermined period of time.

Step (S330) is, in step (S320), when the number of retransmissions of the transmission signal from the second control module 402 to the first control module 401 exceeds the range of the preset number, the first control module 401 ) Or the second control module 402 is initialized. Of course, in this process, it may be configured to initialize both the first control module 401 and the second control module 402, and even if all of the first control module 401 and the second control module 402 are initialized a predetermined number of times, if not processed as a valid value, an alarm is sent to the user. Can be provided to inform the failure or damage of the communication port side.

In the above, the present specification has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention, but this is only exemplary, and those skilled in the art can use various modifications and equivalents from the embodiments of the present invention. It will be appreciated that embodiments are possible. Therefore, the scope of protection of the present invention should be determined by the claims.
