Description

Technical Field

[0001] The present invention is a multifunctional storage system for error recovery of an execution control module. More specifically, it relates to a multifunctional storage system which uses a first control module and a second control module as two microcomputers. If an error occurs in each of the above modules, repair is performed in different ways, thereby improving the stability of the system. Background Art

[0002] With the recent deterioration of fine dust concentration, not only the air quality of indoor spaces, but also the handling and management of clothes, shoes, quilts, etc. that may be attached with various pollutants floating outdoors and indoors have attracted increasing attention. As a result, devices for removing pollutants and managing clothes, shoes, quilts, etc. have been developed, and the demand for devices with various functions related to this has also tended to increase.

[0003] Generally, a clothing care device cleans clothing through a dust shaking, humidification, dehumidification and finishing process. Such dust shaking, humidification, dehumidification and finishing steps are controlled by a microcomputer (hereinafter referred to as "microcomputer") in the clothing care device. More specifically, the microcomputer controls electronic devices such as a blower and a heat pump module in a mechanical room of the clothing care device, thereby achieving cleaning of clothing.

[0004] A microcomputer may refer to a microprocessor that constitutes the calculation processing unit of a computer with one or more large-scale integrated circuits (LSI), and a microcomputer equipped with a pad for mounting interface circuits with storage devices and peripheral devices, and can receive various control signals and electrical signals, and control various devices driven by receiving electrical signals. This microcomputer can store a variety of algorithms and various data in order to directly control electronic products, and can process and generate control signals every time it receives a specific input signal.

[0005] For example, when a microcomputer equipped in a clothing care device inputs a command to work the clothing care device, it outputs a signal for controlling a blower, a heat pump module, etc. by calculating stored algorithms or data, thereby executing the entire process of cleaning clothes.

[0006] In addition, the microcomputer may malfunction due to various reasons such as calculation errors that may occur during repeated calculations, or input of noise or erroneous signals. For example, the microcomputer may fail to receive or respond to external signals due to surges such as system failures, or may fall into an erroneous operating state such as a runaway phenomenon that generates an output signal that is completely different from the expected signal. Accordingly, if an erroneous operating state of the microcomputer occurs, the electronic equipment installed with the microcomputer and various devices including the microcomputer cannot be normally controlled or operated, and thus it is necessary to recognize and correct it.

[0007] As for the prior art for detecting the erroneous working state of a microcomputer and restoring it, Korean Patent Publication No. 1997-0071209 is disclosed. The prior art is a "microcomputer operation monitoring control device", which discloses a control device having an external monitoring timing unit and automatically initializing the microcomputer when the normal working state of the microcomputer is restored. However, the prior art is a structure using a single microcomputer, and there is no means to replace such a microcomputer when an erroneous working state occurs, so it has a problem of poor performance in maintaining system stability.

[0008] Therefore, recently, there has been increasing attention paid to the necessity of a technology for controlling a laundry treating apparatus using a plurality of microcomputers to improve the stability of the system and to enable the laundry treating apparatus to operate normally even when a specific microcomputer malfunctions.

[0009] (Patent Document 1) Korean Patent Publication No. 1997-0071209 Summary of the invention

[0014] Technical Solution

[0015] In order to solve the problems mentioned above, the present invention provides a multifunctional storage system, which uses a predetermined operation signal to control work, and the multifunctional storage system includes: a memory unit 410, the memory unit 410 is used to store control information; a first control module 401, if an error of the first control module 401 is confirmed, after the first control module 401 is initialized, the control information is loaded from the memory unit 410, and the operation signal is sent to the second control module 402 using the control information; and a second control module 402, if an error of the second control module 402 is confirmed, after the second control module 402 is initialized, the control information is requested from the first control module 401 and received, the operation signal is generated using the received control information, and the work is controlled using the operation signal transmitted to the second control module 402 or generated with the help of the second control module 402.

[0016] In addition, preferably, the first control module 401 is a module electrically connected to the operating unit 610 .

[0017] In addition, preferably, the multifunctional storage system includes: a storage room 100; and a mechanical room 200, the control information is information about the working state of the mechanical room 200, and the operation signal is a signal of a command for operating the mechanical room 200.

[0018] In addition, preferably, when the first control module 401 uses the control information to send an operation signal to the second control module 402, the first control module 401 is restored by using the control information. If it is confirmed through the control information that the mechanical room 200 is executing a humidification mode or a dehumidification mode, an operation signal for executing a forced dehumidification mode of the mechanical room 200 is sent from the first control module 401 to the second control module 402, thereby generating an operation signal for the forced dehumidification mode of the mechanical room 200 of the second control module 402, and the forced dehumidification mode of the mechanical room 200 is executed with the aid of the operation signal.

[0019] In addition, preferably, the forced dehumidification mode of the machine room 200 is formed in a manner that the dehumidification intensity or the execution time is variable, and the dehumidification intensity or the execution time depends on the execution time of the humidification mode of the machine room 200 .

[0020] In addition, preferably, when the first control module 401 confirms the mode being executed by the machine room 200 using the control information, if it is confirmed that the machine room 200 is in the standby mode, the first control module 401 keeps the machine room 200 in the standby mode.

[0021] In addition, preferably, when the second control module 402 generates an operation signal using the control information received by the second control module 402, it confirms whether the mechanical room 200 is working through the control information. If it is confirmed that the mechanical room 200 is working, an operation signal is generated to allow the mechanical room 200 to continue working.

[0022] In addition, preferably, the control information includes the mode of the machine room 200, the remaining time of the mode, and information of a program executed by combining at least one of the modes in a time series. The operation signal is an electrical signal related to the remaining time of the mode being executed by the machine room 200 and the remaining mode of the program being executed by the machine room 200 when the error of the second control module 402 is confirmed.

[0023] In addition, preferably, when the second control module 402 confirms that the machine room 200 is in the standby mode based on the control information, the second control module 402 continues to keep the machine room 200 in the standby mode.

[0024] In addition, preferably, the memory unit 410 receives and stores the control information from the second control module 402, and the second control module 402 transmits the control information to the memory unit 410 at a set time period, or transmits the control information to the memory unit 410 each time the mode of the machine room 200 changes.

[0025] In addition, preferably, the operation signal further includes a compensation operation signal of the mode being executed by the machinery room 200, and the compensation operation signal further increases the humidification intensity or the dehumidification intensity in the mode.

[0026] In addition, preferably, the first control module 401 and the second control module 402 are formed to realize communication in a protocol manner by using a predetermined sending signal. When the second control module 402 requests the control information from the first control module 401, if the sending signal of the second control module 402 does not match the protocol of the first control module 401, the first control module 401 processes the sending signal of the second control module 402 as an invalid value, and the second control module 402 retransmits the sending signal to re-request the control information to the first control module 401, and retransmits it within a set number of times until the first control module 401 processes the sending signal as a valid value. If the number of times the sending signal is retransmitted from the second control module 402 to the first control module 401 exceeds the set number of times, either the first control module 401 or the second control module 402 is initialized.

[0027] In addition, preferably, the storage room 100 side has the first control module 401, the memory unit 410 and the display panel unit, and the machine room 200 side has the second control module 402.

[0028] Effects of the Invention

[0029] The present invention utilizes two microcomputers and enables them to communicate with each other, so that the structure of the user interface can be freely drawn and can be flexibly expanded or reduced, thereby increasing the scalability and compatibility.

[0030] Furthermore, when errors are detected in the first control module and the second control module, error recovery methods are formed differently from each other, so that in terms of stability, the most optimized error recovery method can be provided to the first control module having an operating unit and the second control module controlling the machine room.

[0031] Furthermore, if an error occurs when the machine room is operating in any mode, since the second control module is connected to the first control module, the operation of the machine room can be restored stably in a very short time, thereby preventing damage to the clothes stored in the storage room.

[0064] In order to explain the "multi-functional storage system", the following description is based on the situation where clothes are stored in the storage room and cleaned, but it is clear in advance that in addition to clothes, bedding, dolls, etc., which need periodic cleaning, can also be stored in the storage room and cleaned.

[0065] In addition, the term "program" used below is a higher level concept of "mode". For example, "clothing care program" is a concept in which "pre-treatment mode", "humidification mode", "dehumidification mode" and "post-treatment mode" are connected in a time series. The user can select "program" or just "mode".

[0066] 1. Description of the multifunctional storage system structure

[0067] Reference Figures 1 to 3 The multifunctional storage system according to the present invention includes a storage room 100 , a mechanical room 200 , a recycling module 300 , a storage unit 410 , and control modules 401 , 402 .

[0068] The storage chamber 100 is a space for storing clothes and the like and removing pollutants or malodorous substances. For this purpose, after the temperature inside the storage chamber 100 rises to a high temperature, natural humidified air flows in as circulating air and can be circulated. On the inner side of the storage chamber 100, a circulating filter disassembly and assembly portion (not shown), a circulating air inlet, and a circulating air outlet are arranged on the lower surface. The circulating filter disassembly and assembly portion is provided as an opening that allows easy disassembly and assembly of the circulating filter unit 229 located in the machine room 200 for maintenance, replacement, etc.

[0069] The circulating air inlet 141 and the circulating air outlet 142 are openings for allowing the circulating air inside the storage chamber 100 to flow in and out from the machine chamber 200, respectively. The circulating air inlet is formed to communicate with the fan unit 230 and discharge the air from the machine chamber 200 to the storage chamber 100, and the circulating air outlet is formed to circulate the air from the storage chamber 100 to the machine chamber 200. In addition, the portion in the storage chamber 100 that communicates with the circulating air inlet is formed to be inclined toward the upper side, so that the air flowing in from the circulating air inlet has a predetermined angle from the bottom surface inside the storage chamber 100 to the upper side and is discharged to the inside of the storage chamber 100 (meaning that it is not discharged in a vertical direction, but discharged in an inclined manner). As a result, compared with the case where the circulating air discharged from the circulating air inlet is in a vertical direction, it contacts the clothes stored in the storage chamber 100 with a wider area, thereby improving the cleaning efficiency.

[0070] The machine room 200 is a space that circulates air in the "clothing care program" by allowing air to flow in from the storage room 100 and be filtered, and then flowing out as circulating air to naturally humidify the air. The machine room 200 includes an air inlet 210, a first flow path 220, a fan unit 230, a second flow path 240, an air outlet 250, a dehumidifier 260, a water supply tank 270, and a condensation tank 280.

[0071] The air intake port 210 is a portion for sucking outside air into the machine room 200. The air exhaust port 250 is a portion for receiving outside air filtered from the second flow path 240 and discharging it to the outside. The air intake port 210 and the air exhaust port 250 can be opened or closed according to selection. A cleaning filter unit disassembly portion (not shown) is provided at the air intake port 210, so that a cleaning filter unit 219 can be provided. The cleaning filter unit 219 plays a role in filtering the outside air sucked in the 'air cleaning mode' which is another program of the multifunctional storage system, and may include a pre-filter, a high-efficiency air filter, etc., but is not limited thereto.

[0072] The first flow path 220 is connected to the air inlet 210, the second flow path 240 and the fan unit 230. A circulation filter unit 229 is provided inside the first flow path 220. The circulation filter unit 229 can filter the circulating air. Since the circulation filter unit 229 may include a humidification filter, when the water retained in the supply water tank 270 is supplied to the humidification filter, the moisture is provided to the circulating air passing through the humidification filter, thereby forming naturally humidified air. The user can disassemble and assemble the circulation filter unit 229 by opening a door (not shown) and approaching the circulation filter disassembly and assembly portion (not shown).

[0073] Due to the operation of the fan unit 230, the air inside the storage room 100 flows into the second flow path 240 through the circulating air outlet 142, and flows back into the first flow path 220 toward the fan unit 230. In this process, the air passes through the humidification filter of the circulation filter unit 229 to become naturally humidified air. It passes through the second flow path 240 again and is supplied to the storage room 100 through the circulating air inlet. This process is repeated, so that the circulating air continues to circulate between the storage room 100 and the machine room 200. The circulating air contains pollutants or malodorous substances in the storage room 100, and since they are not discharged to the outside, a comfortable environment is provided to the user.

[0074] The second flow path 240 receives filtered external air or circulating air from the fan unit 230. The second flow path 240 is selectively connected to any one of the storage chamber 100 and the exhaust port 250, and includes a first flow path conversion component 241 and a second flow path conversion component 242 for controlling the second flow path 240. The first flow path conversion component 241 and the second flow path conversion component 242 change the flow path by working in pairs. In one embodiment, the first flow path conversion component 241 and the second flow path conversion component 242 may be components that rotate around an axis, or may be any mechanism that selectively changes the flow path.

[0075] The dehumidifier 260 is used to perform the function of dehumidifying the circulating air flowing in the storage chamber 100. The dehumidifier 260 may be a heat pump, for example, but is not limited thereto. The dehumidifier 260 may generate heat during the dehumidification process, but this heat will not be discarded, but can be used for clothing care. For example, after the storage chamber 100 is heated to about 50 to 70 degrees Celsius by the heat generated during the dehumidification process of the dehumidifier 260, the normal temperature circulating air is received from the second flow path 240 through the circulating air inlet, so that pollutants and even odorous substances such as clothes can be removed. As another example, as mentioned above, the heat generated during the dehumidification process of the dehumidifier 260 is supplied to the humidification filter of the circulation filter unit 229, or is provided to the pipe connecting the supply tank 270 and the humidification filter, so that the naturally humidified air that performs the circulating air function can also be heated. The above-mentioned temperature is an example, not limited to this, and various changes can be made. In addition, one of the dehumidifier 260 and the circulation filter unit 229 (ie, the humidification filter) may be selectively operated so as not to interfere with each other.

[0076] The supply water tank 270 retains water to be supplied to the humidification filter provided in the circulation filter unit 229. For this purpose, it is connected to the circulation filter unit 229 by a pipe. The condensation water tank 280 collects and retains condensed water generated by the storage chamber 100, or collects and retains condensed water generated in the process of saturated humid air generated by the storage chamber 100 flowing into the first flow path 220 or the second flow path 240 of the machine room 200 and condensing. For this purpose, the storage chamber 100 and / or the first flow path 220 and / or the second flow path 240 are connected by a pipe. In order to fill the water or remove the filled condensed water, it is preferred that both the supply water tank 270 and the condensation water tank 280 are easily accessible to the user.

[0077] Although the machine room 200 may be located in any direction with respect to the storage room 100, it is preferably located at the lower part of the storage room 100. This is because the condensed water or saturated wet air condensed in the storage room 100 can flow into the machine room 200 due to its own weight and be discharged to the outside through the condensed water tank 280.

[0078] The recirculation module 300 helps the circulation of the circulating air. Since the recirculation module 300 recirculates the circulating air on the upper side of the storage chamber 100, the convection phenomenon can be realized more smoothly in the entire storage chamber 100. In addition, since the recirculation module 300 operates independently of the operation of the machine chamber 200, it can also operate to remove pollutants such as clothes stored in the storage chamber 100. Figures 1 to 3 The diagram is based on a state in which the recirculation module 300 is provided, but it is of course not necessary to provide the recirculation module 300. In addition, even if the recirculation module 300 is provided, when the fan unit 230 is operated, the recirculation module 300 does not operate but can operate independently.

[0079] The memory unit 410 is a space for storing information about the multifunctional storage system. The memory unit 410 may include an EEP-ROM (Electrically Erasable and Programmable ReadOnly Memory), but is not limited thereto as long as it is a type that can store memory. The EEP-ROM can write and delete information with the help of the control modules 401 and 402. The EEP-ROM can be composed of a non-volatile memory, and the information stored in the non-volatile memory will be retained and will not be deleted even if the power supply stops due to power disconnection. In the following description, the memory unit 410 and the control modules 401 and 402 are described as separate structures, but this refers to functional separation, not physical separation. According to the system and equipment embodied, the memory unit 410 and the control modules 401 and 402 can be formed as one body.

[0080] The first control module 401 is a module electrically connected to the operation unit 610. When the user selects a desired program or mode and inputs it into the operation unit 610, the first control module 401 sends an operation signal to the second control module 402. Figure 1 The operation unit 610 is disposed outside the door 600 for the convenience of the user's input operation. In addition, a display panel is disposed to visually provide the user with information on the status of the multifunctional storage system in operation, and the display panel can be formed in a touch-sensitive manner for the user to input.

[0081] The second control module 402 is a module for electrically controlling the components located in the machine room 200. The second control module 402, which receives the operation signal from the first control module 401, transmits the command signal to the components in the machine room 200 in an electrically manner, so that they operate. For example, when the user selects the clothing care program, it means that the clothing care program is selected and input to the first control module 401, and the second control module 402 receives the operation signal related to the pre-treatment mode, humidification mode, dehumidification mode and post-treatment mode of the clothing care program from the first control module 401, which is executed in a time series manner, and controls the operation of the components corresponding to each mode.

[0082] In addition, the first control module 401 and the memory unit 410 are disposed on the storage room 100 side, so as to prevent electronic interference of components in the machine room 200. The second control module may be disposed in the machine room 200.

[0083] 2. Description of the mechanical room mode of the multifunctional storage system

[0084] (1) Description of clothing care procedures

[0085] Step S100 is a step of executing a 'clothing care program'.

[0086] The machine room 200 can execute the detailed processes constituting the clothing care program, namely, the pre-treatment mode, the humidification mode, the dehumidification mode, and the post-treatment mode. In the following, the clothing care program is roughly divided into the pre-treatment mode, the humidification mode, the dehumidification mode, and the post-treatment mode for explanation, but an additional mode related to the cleaning of the clothing can also be added. In addition, the operation of the clothing care program can operate the machine room 200 in a manner of sequentially executing the pre-treatment mode, the humidification mode, the dehumidification mode, and the post-treatment mode, but the pre-treatment mode and the post-treatment mode can be partially or completely omitted according to the user's choice.

[0087] 1) Description of humidification mode

[0088] Reference Figure 2 , the operation of the structure of the machine room 200 in the humidification mode will be described.

[0089] In the humidification mode, the air sucked by the fan unit 230 passes through the circulation filter unit 229 and forms natural humidified air. In order to circulate the natural humidified air to the storage chamber 100, the circulation air inlet and the circulation air outlet are opened. Among them, the humidification filter is arranged in the circulation filter unit 229, and water is supplied from the supply tank 270 to the humidification filter of the circulation filter unit 229, and it can also be formed so that the water retained in the supply tank 270 is forcibly supplied by using a supply pump (not shown).

[0090] The humidification mode circulates the naturally humidified air to the storage chamber 100, thereby humidifying the internal environment of the storage chamber 100. Accordingly, the clothes stored in the storage chamber 100 can be humidified. The air particles contained in the naturally humidified air will combine with the pollutant particles and the malodorous substance particles adhering to the clothes, and when the dehumidification mode described later is operated, the pollutant particles and the malodorous substance particles will be removed from the clothes in the process of dehumidifying the clothes.

[0091] in addition, Figure 2 The fan unit 230 is described as being an intake fan, but may be an exhaust fan. In this case, the configuration of the structure inside the machine room 200 may be rearranged in a manner suitable for the exhaust fan.

[0092] 2) When working in dehumidification mode

[0093] Reference Figure 3 , the operation of the structure of the machine room 200 in the dehumidification mode is described.

[0094] In the dehumidification mode, the dehumidifier 260 in the machine room 200 operates to dehumidify the circulating air flowing in the storage room 100. In order to dehumidify 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 operation of the dehumidification mode may be retained in the condensed water tank 280. By executing the dehumidification mode, pollutant particles and odorous material particles adhering to the clothes can be removed from the clothes.

[0095] 3) When working in pre-processing mode and post-processing mode

[0096] Reference Figure 3 , the operation of the structure of the machine chamber 200 in the pre-processing mode and the post-processing mode will be described.

[0097] The pretreatment mode is the starting step of the clothing care program, and performs the function of exhausting air to initially remove dust or pollutants of relatively large particle size adhering to clothing, etc. The pretreatment mode is also called "air shower mode", which means the process of spraying air with strong force. Before formally removing pollutants from the clothing adhering to the inside of the storage chamber 100, the pollutants are shaken off in advance, thereby improving the cleaning efficiency of the clothing. In the pretreatment mode, the circulation filter unit 229 and the dehumidifier 260 do not work, and only the fan unit 230 works.

[0098] The post-processing mode is the final step of the clothing care program, and performs the function of supplying air through the fan unit 230 to remove foreign matter that may still remain in the clothing and re-dry the inside of the storage chamber 100. The post-processing mode is also called the 'air smoothing mode'. Although the structure of the machine chamber 200 in the pre-processing mode and the post-processing mode is the same, the output of the fan unit 230 can be controlled differently from each other. For example, the output of the fan unit 230 in the pre-processing mode can be formed to be relatively larger than the output of the fan unit 230 in the post-processing mode.

[0099] In addition, this manual explains that the humidification mode and the dehumidification mode are executed between the pre-treatment mode and the post-treatment mode, and the humidification mode and the dehumidification mode can be repeated multiple times. The user can adjust the number of executions of the humidification mode and the dehumidification mode according to the type of clothes or the type of fabric stored in the storage room 100.

[0100] Moreover, in the pre-processing mode and the post-processing mode, the storage chamber 100 and the machine chamber 200 are interconnected, and are preferably performed in a state isolated from the outside air. In particular, when the pre-processing mode is performed, if the machine chamber 200 is not isolated from the outside air, foreign particles inside the storage chamber 100 may be discharged to the outside of the multifunctional storage system, resulting in poor air quality in the space where the multifunctional storage system is configured. In the post-processing mode, in order to isolate the influence of humidity and temperature on the space where the multifunctional storage system is configured, it is preferred to operate in a state where the machine chamber 200 is isolated from the outside air.

[0101] (2) Description of air cleaning mode

[0102] Reference Figure 4 , the operation of the structure of the machine room 200 in the air cleaning mode is described.

[0103] The air cleaning mode is a mode in which only the machine room 200 operates to clean the outside air independently of the storage room 100. That is, when the outside air is polluted, clean clothes etc. can be placed inside the storage room 100, so the outside air does not flow into the storage room 100.

[0104] If the user selects the air cleaning mode, the exhaust valve 650 of the door 600 is opened, and the air inlet 210 is also opened.

[0105] The first flow path switching member 241 and the second flow path switching member 242 of the machine room 200 operate to connect the second flow path 240 with the exhaust port 250 and isolate it from the storage room 100 and the first flow path 220. In this process, the storage room 100 and the machine room 200 become independent spaces.

[0106] The fan unit 230 is working. Due to the operation of the fan unit 230, external air flows into the first flow path 220 toward the fan unit 230 through the air inlet 210. In the process of passing through the air inlet 210, the external air is filtered by means of the cleaning filter unit 219 located at the air inlet 210. In the process of passing through the first flow path 220, it can be further filtered by means of the circulation filter unit 229 located at the first flow path 220. In this way, in the process of forcibly circulating the air by means of the fan unit 230, the humidification filter located in the circulation filter unit 229 can be dried. Therefore, by drying the humidification filter that is usually supplied with water from the water supply tank 270, the proliferation of bacteria on the humidification filter is prevented, and the problem of odor generation can be solved at one stroke. The filtered external air passing through the fan unit 230 passes through the second flow path 240 and is exhausted to the outside through the exhaust port 250.

[0107] By repeating this process, the multifunctional storage system according to the present invention performs a function of an air cleaner. External air continues to flow into the machine room 200 and is filtered, and the filtered air continues to be exhausted.

[0108] Since the air cleaning mode can be performed regardless of whether the user opens the door 600, it is preferable. During the operation of the air cleaning mode, the user can place clothes and the like inside the storage chamber 100 or take out clothes and the like by freely opening the door 600. The water supply tank 270 can be filled with water and the water in the condensation tank 280 can be drained at any time. Since the door 600 does not cover the air inlet 210 and the air outlet 250 is in a state of being open inside the door 600, the opening of the door 600 does not affect the operation of the air cleaning mode.

[0109] When the user is far away from the multifunctional storage system, that is, cannot clearly see the position of the operating unit 610, the user can confirm whether the system is currently operating in the air cleaning mode or the clothing care program by only confirming whether the exhaust valve 650 is open.

[0110] 3. Instructions for error recovery of the control module of the multi-functional storage system

[0111] (1) When an error is detected in the first control module

[0112] When an error is detected in the first control module 401, in order to explain the method of recovering the error, refer to Figure 5 and Figure 6 Provide explanation.

[0113] The first control module 401 is electrically connected to the memory unit 410 so as to be communicable, and this may be implemented as a wire harness for wired connection.

[0114] The error recovery method of the first control module 401 includes steps S100 to S124.

[0115] The error confirmation of the first control module 401 can be performed by a watchdog as a monitoring means. The watchdog can be configured to confirm the abnormal state of the first control module according to a set time period. More preferably, it can be configured to confirm in real time.

[0116] Step S100 is a step of initializing the first control module 401 , which means resetting.

[0117] Step S110 is a step in which the first control module 401 loads control information from the memory unit 410. The operation of the machine room 200 mentioned above can store the mode information of the machine room 200 in the memory unit 410 each time any mode is ended. The first control module 401 can receive the type of the mode and program in the current operation and the remaining time information through the memory unit 410.

[0118] Step S120 is a step in which the first control module 401 sends an operation signal to the second control module 402 using the control information loaded from step S110, and includes steps S121 to S124.

[0119] Specifically, step S121 is a step of using the control information to restore the first control module 401. In this process, the display panel linked to the first control module 401 can be configured to display the restored control information.

[0120] Step S122 is a step in which the first control module 401 uses control information to confirm whether the mechanical room 200 is executing a humidification mode or a dehumidification mode. If the mechanical room 200 is executing a humidification mode, residual moisture is left in the current storage room 100. If it is not removed, there is a risk of damaging clothing materials. If the mechanical room 200 is executing a dehumidification mode, it means that the dehumidification mode has not been terminated, and in this case, the problem of residual moisture will also occur. That is, in step S122, it is a step to confirm whether there is residual moisture in the current storage room 100, which is related to the execution of the forced dehumidification mode to be executed later.

[0121] Step S123 is a step in which, when it is confirmed in step S122 as the previous step that the machine room 200 is in the humidification mode or the dehumidification mode, the first control module 401 sends an operation signal to the second control module 402 to execute the forced dehumidification mode of the machine room 200. That is, it means that the current state of the storage room 100 has residual moisture and is in a state where the residual moisture needs to be removed.

[0122] Step S124 is to generate an operation signal of the forced dehumidification mode of the machine room 200 by means of the second control module 402, and execute the forced dehumidification mode of the machine room 200. The 'forced dehumidification mode' can work in the same way as the aforementioned 'dehumidification mode', but the specific control information such as the dehumidification intensity and time can be formed differently.

[0123] Furthermore, the forced dehumidification mode of the machine room 200 executed in step S124 can be set as follows, so that the dehumidification intensity or the execution time of the forced dehumidification mode is variable, and the dehumidification intensity or the execution time of the forced dehumidification mode depends on the execution time of the humidification mode of the machine room 200. The humidity of the storage room 100 will be different according to the execution time of the humidification mode, and the execution time of the humidification mode and the humidity of the storage room 100 are matched and set in the first control module 401 or the second control module 402, so that it is possible to configure a configuration without configuring an expensive and precise humidity sensor inside the storage room 100.

[0124] (2) When an error is detected in the second control module

[0125] When an error is detected in the second control module 402, in order to explain the method of recovering the error, refer to Figure 7 and Figure 8 Provide explanation.

[0126] The second control module 402 is electrically connected to the first control module 401 so as to communicate with each other, which can be formed by a wired connection harness. In addition, the first control module 401 and the second control module 402 can also be configured with a communication module (not shown) for wireless communication.

[0127] The error recovery method of the second control module 402 includes steps S200 to S232 .

[0128] Step S200 is a step of initializing the second control module 402 , which means resetting.

[0129] Step S210 is a step in which the second control module 402 requests control information from the first control module 401. In step S200, since the second control module 402 is initialized, the operation of the components of the machine room 200 will also be reset in a very short time, such as a few milliseconds (ms), and the second control module 402 requests control information from the first control module 401, thereby obtaining control information including the currently running program, mode, and remaining time.

[0130] Step S220 is a step in which the second control module 402 receives control information from the first control module 401 .

[0131] 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 step S231 and step S232 .

[0132] Step S231 is a step in which the second control module 402 confirms whether the machine room 200 is in operation through control information, that is, it is the first time to confirm whether the machine room 200 is in operation or in a standby state.

[0133] Step S232 is a step of generating an operation signal to continuously execute the operation of the machine room 200 if it is confirmed in step S231 that the machine room 200 is in operation. To be more specific, the control information includes the mode information of the machine room 200, the remaining time information of the mode being executed (or the execution time information of the mode), and the program information of different modes combined in a time series. In order to continuously execute the operation of the machine room 200, the remaining time information and the remaining mode information are included, and the operation signal means an electrical signal for the remaining time information and the remaining mode information.

[0134] In addition, the operation signal in step S232 may also include a compensation operation signal. The compensation operation signal may further increase the humidification intensity or humidification time in the humidification mode. Moreover, the dehumidification intensity or dehumidification time may also be further increased in the dehumidification mode. As a modified example of the above, the humidification intensity and the dehumidification intensity may be increased only during a set time period, and if the humidification mode and the dehumidification mode are executed for more than the set time period, the humidification intensity and the dehumidification intensity may be returned to a normal state.

[0135] (3) If there is a communication error between the first control module and the second control module

[0136] Reference Figure 8 , indicating a communication error between the first control module 401 and the second control module 402 .

[0137] The first control module 401 and the second control module 402 are configured to communicate with each other using electrical signals and in a protocol manner.

[0138] At this time, when the second control module 402 requests control information from the first control module 401, if the signal sent by the second control module 402 does not match the protocol of the first control module 401, error recovery is performed by executing steps S310 to S330.

[0139] Step S310 is a step in which the first control module 401 processes the transmission signal of the second control module 402 as an invalid value. The first control module 401 and the second control module 402 respectively set the range of the transmission and reception protocol value, and if the value is not within the set range, it is processed as an invalid value.

[0140] Step S320 is a step in which the second control module 402 retransmits a signal for re-requesting control information to the first control module 401, and retransmits within a set number of times until the first control module 401 processes the signal as a valid value. At this time, when the second control module 402 re-requests control information from the first control module 401, the request is made with a set time as a period.

[0141] Step S330 is a step of initializing either the first control module 401 or the second control module 402 if the number of retransmissions of the signal sent from the second control module 402 to the first control module 401 exceeds the range of the set number of times in step S320. Of course, in this process, both the first control module 401 and the second control module 402 may be initialized, and even if both are initialized according to the predetermined number of times, if they are not processed as valid values, a warning is provided to the user to inform the user of a failure or even damage on the communication interface side.

[0142] In the above, in this specification, the embodiments shown in the drawings are described so that those skilled in the art can easily understand and implement the present invention, but this is only exemplary. For those skilled in the art, various modifications and equivalent other embodiments can be understood from the embodiments of the present invention. The protection scope of the present invention shall be determined according to the patent claims.
