Description

Technical Field

[0001] The present application relates to the field of washing equipment, and in particular to a fault detection method, device, storage medium and electronic equipment. Background Art

[0002] Washing equipment can be understood as equipment that runs a washing program to wash objects, and is widely used in life. The operation stages of washing equipment such as dishwashers include a washing stage, a drying stage, and a storage stage, and the above multiple stages are performed in sequence. In other words, the washing equipment runs the washing program, the drying program, and the storage program in sequence as time passes, and can also run the drying program to dry objects.

[0003] According to the working requirements of the washing equipment, different drying methods can be used to run the drying program. Drying methods are generally divided into active, passive and adsorption drying. Active drying usually refers to a drying method that directly or indirectly heats the water through an external energy source to evaporate the water. Adsorption drying usually refers to a drying method that uses specific adsorption materials (such as silica gel, molecular sieves, etc.). When the air containing moisture flows through a drying tower filled with such adsorbents, the moisture is absorbed by the adsorbent, thereby achieving a drying effect. Passive drying is a drying method that uses a fan to forcibly remove moisture from the cavity. Washing equipment such as dishwashers often use passive drying methods to dry the washing cavity containing kitchen utensils. Utility Model Content

[0004] The embodiments of the present application provide a fault detection method, device, storage medium and electronic device, which can detect whether a washing device can operate normally and improve the reliability of the washing device. The technical solution is as follows:

[0005] The embodiment of the present application provides a washing device, the washing device comprises a controller, a washing cavity and an exhaust device, the exhaust device comprises an exhaust port and a first air inlet, the first air inlet and the washing cavity are connected, the exhaust port is connected to the external environment, and a regulating valve is arranged in the exhaust device:

[0006] The controller is connected to the exhaust device, and the controller is used to detect whether the washing cavity is connected to the external environment before controlling the operation of the washing device, and send a first adjustment instruction to the exhaust device when it is detected that the washing cavity is connected to the external environment;

[0007] The exhaust device adjusts the regulating valve to close the first air inlet in response to the first regulating instruction, so that the washing cavity is not connected to the external environment;

[0008] The controller is also used to detect whether the washing cavity is connected to the external environment after sending the first adjustment instruction and a first preset time has passed, and determine that the washing device is faulty when it is detected that the washing cavity is still connected to the external environment after sending the first adjustment instruction a first preset number of times.

[0009] The beneficial effects brought about by the technical solutions provided by some embodiments of the present application include at least:

[0010] The present application proposes a washing device including a controller, a washing cavity and an exhaust device, wherein the exhaust device includes an exhaust port and a first air inlet, the first air inlet is connected to the washing cavity, the exhaust port is connected to the external environment, and a regulating valve is arranged in the exhaust device. The drying principle of the washing device is to determine the preset conditions for drying completion based on the disconnected cavity and the external environment before operation, and to determine that the parameters of the cavity such as temperature and humidity meet the preset conditions after running the drying program, and to determine that the drying of the washing cavity is completed. In other words, if the cavity is detected to be connected to the external environment before the washing device is operated, it is impossible to determine whether the drying in the cavity is completed after running the drying program. Therefore, when the controller detects that the washing cavity is connected to the external environment before controlling the operation of the washing device, it sends a first adjustment instruction to the exhaust device. In response to the first adjustment instruction, the exhaust device adjusts the regulating valve to close the first air inlet so that the washing cavity is not connected to the external environment. The controller detects whether the washing cavity is connected to the external environment after sending the first adjustment instruction and after a first preset time, and determines that the washing device is faulty when the washing cavity is still connected to the external environment after sending the first adjustment instruction to a first preset number of times. In other words, when the exhaust device repeatedly responds to the first adjustment instruction to adjust the regulating valve to close the first air inlet, the controller still detects that the washing chamber is connected to the external environment and determines that the washing device has a fault. The washing device proposed in this application can detect faults of the washing device before operation, ensure that the washing device can operate normally, such as washing programs, drying programs, storage programs, etc., and improve the working reliability of the washing device.

[0020] The present application is described in detail below with reference to specific embodiments.

[0021] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in the embodiments of this specification are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions. For example, the object features, interactive behavior features and user information involved in this specification are all obtained with full authorization.

[0022] Washing equipment, which can be understood as equipment that runs a washing program to dry objects, is widely used in life. The operation stages of washing equipment such as dishwashers include a washing stage, a drying stage, and a storage stage, and the above multiple stages are carried out in sequence. In other words, the washing equipment runs the washing program, the drying program, and the storage program in sequence as time passes, and can also run the drying program to dry objects.

[0023] like Figure 1 The figure is a schematic diagram of the structure of a washing device provided in an embodiment of the present application. Figure 1 The washing device shown includes a controller 103, a washing cavity 101 and an exhaust device 102. The exhaust device 102 includes an exhaust port and a first air inlet. The first air inlet is connected to the washing cavity 101, and the exhaust port is connected to the external environment. A regulating valve is arranged in the exhaust device 102.

[0024] By adjusting the state of the regulating valve 1021, the opening of the first air inlet of the exhaust device 1021 in the external environment is controlled, that is, the flow rate of the external environment entering the washing chamber 101 is adjusted. In other words, the opening of the regulating valve 1021 is related to the flow rate of the gas allowed to pass through the first air inlet. The larger the opening of the regulating valve 1021, the larger the flow rate of the gas allowed to pass through the first air inlet, and the larger the opening of the regulating valve 1021, the smaller the flow rate of the gas allowed to pass through the first air inlet.

[0025] like Figure 1 As shown, the regulating valve 1021 is in the second state, and the valve plate of the regulating valve 1021 is in Figure 1 At 1 of the upper exhaust device 102, the washing chamber 101 is connected to the external environment through the first air inlet and the exhaust port. Figure 2 As shown, the regulating valve 1021 is in the first state, and the valve plate of the regulating valve 1021 is in Figure 1 2 of the upper exhaust device 102, at this time, the washing chamber 101 is not connected to the external environment.

[0026] Figure 1The washing equipment shown can be any type of washing equipment such as a hot air circulation oven, a spray dryer, a flash dryer, a vacuum drying oven, a belt dryer, a fluidized bed dryer, a drum dryer, etc. For example, a hot air circulation oven is suitable for drying and curing of food, chemical raw materials, electronic components, ceramic products, etc. The hot air circulation evenly heats the cavity through the circulating hot air system so that the objects placed in the cavity can be dried, and the hot air is discharged to the external environment through the air inlet and exhaust port of the exhaust device. The washing equipment can also be any equipment such as a dishwasher, a microwave oven, etc. that needs to run multiple types of working programs, and the above multiple types of working programs include drying programs. In other words, the present application does not impose any restrictions on the type of washing equipment.

[0027] According to the working requirements of the washing equipment, different drying methods can be used to run the drying program. Drying methods are generally divided into active, passive and adsorption drying. Active drying usually refers to a drying method that directly or indirectly heats the water through an external energy source to evaporate the water. Adsorption drying usually refers to a drying method that uses specific adsorption materials (such as silica gel, molecular sieves, etc.). When the air containing moisture flows through a drying tower filled with such adsorbents, the moisture is absorbed by the adsorbent, thereby achieving a drying effect. Passive drying is a drying method that uses a fan to forcibly remove moisture from the cavity. Washing equipment such as dishwashers often use passive drying methods to dry the washing cavity containing kitchen utensils.

[0028] Therefore, it is necessary to perform fault detection for the washing machine to run the drying program to avoid various faults that cause the washing machine to be unable to continue working. Figure 3 , which is a schematic diagram of a device fault detection method proposed in the present application, which is executed by a controller 101 and an exhaust device 102 .

[0029] In this embodiment, the controller 101 is connected to the exhaust device 102 103. Optionally, the controller 101 can be implemented in at least one hardware form of digital signal processing (DSP), field programmable gate array (FPGA), and programmable logic array (PLA). The above-mentioned processing module can be a combination of one or more of an integrated central processing unit (CPU), a graphics processing unit (GPU), and a modem. Among them, the CPU mainly processes the operating system, user interface, and application programs; the GPU is responsible for rendering and drawing the content to be displayed on the display screen; and the modem is used to process wireless communications. It can be understood that the above-mentioned modem may not be integrated into the integrated processing unit or the micro control unit, but may be implemented separately through a chip.

[0030] Among them, the memory may include a random access memory (RAM) and may also include a read-only memory (Read-Only Memory). Optionally, the memory includes a non-transitory computer-readable storage medium. The memory can be used to store instructions, programs, codes, code sets or instruction sets. The memory may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for at least one function (such as a touch function, a sound playback function, an image playback function, etc.), instructions for implementing the following various method embodiments, etc.; the data storage area may store data involved in the following various method embodiments, etc. The memory may also be optionally at least one storage device located away from the controller 101.

[0031] S101. Before controlling the operation of the washing device, the controller detects whether the washing cavity is connected to the external environment?

[0032] The controller 103 can obtain a drying instruction for controlling the washing device to run a drying program, and the start instruction can be obtained based on the triggering condition of the start instruction. The triggering condition can be set according to actual needs, and the triggering condition can be a time condition, a business type condition, or an operation type condition, for example: triggering the start instruction when a specified time arrives; or triggering the start instruction when a specified business type is executed; obtaining the start instruction when a specified operation type is detected, etc.

[0033] In response to the drying instruction, before controlling the washing device to operate, it is detected whether the washing cavity 102 is connected to the external environment. The method for detecting whether the washing cavity 102 is connected to the external environment may be to detect whether the relevant parameters of the washing cavity 102 and the external environment are consistent. For example, it is detected whether the pressure of the washing cavity 102 is consistent with the pressure of the external environment. If it is detected that the pressure of the washing cavity 102 is consistent with the pressure of the external environment, the washing cavity 102 may be connected to the external environment.

[0034] In one embodiment, the method for detecting whether the washing cavity 101 is connected to the external environment may be: in response to a drying instruction for running a drying program, detecting the state of the regulating valve before running the drying program; if it is detected that the state of the regulating valve is not the first state, determining that the washing cavity is connected to the external environment. In other words, in this embodiment, whether the washing cavity is connected to the external environment is detected by detecting the state of the regulating valve.

[0035] In this embodiment, the washing device further includes a micro switch. The regulating valve 1021 is composed of a micro switch, a valve plate and a control motor. The micro switch is arranged at Figure 1 1 of the exhaust device 102. Before running the drying program, the state of the micro switch is detected. When the micro switch is in a closed state, it indicates that the regulating valve 1021 is in the first state. When the micro switch is in an open state, it indicates that the regulating valve 1021 is not in the first state, and the washing cavity 101 is connected to the external environment.

[0036] In one embodiment, the washing device includes a washing program and a drying program, and the controller 103 controls the washing device to detect whether the washing cavity is connected to the external environment before running the washing program. Before running the washing program, detecting whether the washing cavity 101 is connected to the external environment ensures that heat in the washing cavity will not be lost when the washing program is running, and also ensures that the fault detection method is executed in the washing initialization stage.

[0037] This test starts from low zero, providing the data required for determining the preset conditions for the completion of drying for the subsequent running of the drying program. In other words, the number of rotations of the counter representing the number of times the washing equipment runs the drying program is reset to zero, and the temperature, humidity, pressure data, etc. of the external environment are directly read to provide data for the subsequent running of the washing program and the drying program in sequence. The data is related to running the drying program and determining the preset conditions for the completion of drying of the washing cavity.

[0038] Running the washing program and the drying program in sequence when the washing cavity is not connected to the outside world can reduce the possibility of failure of the washing device when running the washing program and improve the working reliability of the washing device.

[0039] S102. When the controller detects that the washing cavity is connected to the external environment before the washing equipment is operated, the controller sends a first adjustment instruction to the exhaust device. In response to the first adjustment instruction, the exhaust device adjusts the adjustment valve to close the first air inlet to prevent the washing cavity from being connected to the external environment.

[0040] When the controller 103 detects that the washing chamber 101 is connected to the external environment before the washing device is operated, the controller 103 sends a first adjustment instruction to the exhaust device 102 .

[0041] The exhaust device 103 adjusts the regulating valve to close the first air inlet in response to the first regulating instruction, so that the washing chamber 101 is not connected to the external environment. In other words, when it is detected that the washing chamber 101 is connected to the external environment, the regulating valve 1021 is adjusted to the first state of closing the first air inlet.

[0042] like Figure 1 As shown, the exhaust device 102 responds to the first adjustment instruction and instructs the control motor of the regulating valve 1021 to control the valve plate to rotate counterclockwise by a preset angle (for example, 70°) until it is adjusted to the following angle: Figure 2 As shown, the first air inlet is closed, and the washing cavity 101 is not connected to the external environment.

[0043] In another embodiment, the washing device includes a micro switch, and the micro switch is connected to the regulating valve. The exhaust device 102 adjusts the regulating valve 1021 to close the first air inlet by adjusting the micro switch to a closed state. When the exhaust device 102 detects that the micro switch is in a closed state, it determines that the regulating valve is in a state such as Figure 2 The first state is shown.

[0044] S103. After sending the first adjustment instruction and after a first preset time has passed, the controller detects whether the washing cavity is connected to the external environment?

[0045] After sending the first adjustment instruction and after the first preset time has passed, the controller 103 detects again whether the washing chamber 101 is connected to the external environment. The first preset time can be any time set by relevant personnel. For example, the preset time is 80 seconds, and the control motor of the control valve 1021 is controlled to control the valve plate to rotate counterclockwise by a preset angle to adjust the control valve to the first state, and after 80 seconds from the start of rotation to the time when the micro switch is in a closed state, it is detected whether the washing chamber is connected to the external environment.

[0046] In this embodiment, by setting the first preset time length, the accuracy of detecting whether the washing cavity is connected with the external environment after the regulating valve is adjusted to close the first air inlet can be improved, thereby avoiding the problem of detecting whether the washing cavity is connected with the external environment while the regulating valve is still being adjusted, resulting in detection errors.

[0047] S104: After sending the first adjustment instruction to the first preset number of times, the controller detects that the washing cavity is still connected to the external environment, and determines that the washing device is faulty.

[0048] When the controller 103 sends the first adjustment instruction and detects that the washing cavity is connected to the external environment after the first preset time, it can continue to send the first adjustment instruction to the exhaust device 102, so that the exhaust device 102 adjusts the regulating valve to close the first air inlet based on the first adjustment instruction. Until the controller 103 detects that the washing cavity is still connected to the external environment after sending the first adjustment instruction to the first preset number of times, it is determined that the washing device is faulty and the drying program cannot be run. The first preset number of times can be any number set by relevant personnel, for example, 10 times.

[0049] After determining that the washing equipment has failed, the controller 103 may take fault intervention measures, which may include displaying fault information on the equipment, sending alarm prompts, etc., or stopping the operation of the washing equipment, or recording the time and condition of the failure, as well as possible influencing factors, to provide a basis for subsequent analysis, etc.

[0050] In this embodiment, the first adjustment instruction is sent to the exhaust device multiple times to adjust the adjustment valve to the first state to close the first air inlet, and the controller again detects whether the washing cavity is connected to the external environment after each sending of the first adjustment instruction and after a first preset time period, thereby improving the success rate of adjusting the adjustment valve to close the first air inlet so as to smoothly control the washing equipment to run the drying program, attempting to solve the malfunction of the washing equipment and improve the working reliability of the washing equipment.

[0051] S105: When the controller detects that the washing cavity is not connected to the external environment, the controller controls the washing device to operate.

[0052] Exemplarily, the controller 103 detects that the micro switch of the exhaust device 102 is in a closed state, that is, it is determined that the washing chamber 101 is not connected to the external environment, and then controls the washing device to run the drying program normally. During the normal operation of the washing device, the control motor of the exhaust device 102 is instructed to drive the valve plate to rotate clockwise, gradually increasing the opening until the washing chamber meets the preset conditions determined based on the washing chamber not connected to the external environment, and the drying program is determined to be completed. For example, the preset conditions are related to temperature information, and the drying is confirmed to be completed when it is determined that the information such as temperature and humidity in the washing chamber 101 is close to the temperature and humidity of the external environment.

[0053] The present application proposes a washing device including a controller, a washing cavity and an exhaust device, wherein the exhaust device includes an exhaust port and a first air inlet, the first air inlet is connected to the washing cavity, the exhaust port is connected to the external environment, and a regulating valve is arranged in the exhaust device. The drying principle of the washing device is to determine the preset conditions for drying completion based on the disconnected cavity and the external environment before operation, and to determine that the parameters of the cavity such as temperature and humidity meet the preset conditions after running the drying program, and to determine that the drying of the washing cavity is completed. In other words, if the cavity is detected to be connected to the external environment before the washing device is operated, it is impossible to determine whether the drying in the cavity is completed after running the drying program. Therefore, when the controller detects that the washing cavity is connected to the external environment before controlling the operation of the washing device, it sends a first adjustment instruction to the exhaust device. In response to the first adjustment instruction, the exhaust device adjusts the regulating valve to close the first air inlet so that the washing cavity is not connected to the external environment. The controller detects whether the washing cavity is connected to the external environment after sending the first adjustment instruction and after a first preset time, and determines that the washing device is faulty when the washing cavity is still connected to the external environment after sending the first adjustment instruction to a first preset number of times. In other words, when the exhaust device repeatedly responds to the first adjustment instruction to adjust the regulating valve to close the first air inlet, the controller still detects that the washing chamber is connected to the external environment and determines that the washing device has a fault. The washing device proposed in this application can detect faults of the washing device before operation, ensure that the washing device can operate normally, such as washing programs, drying programs, storage programs, etc., and improve the working reliability of the washing device.

[0054] In another embodiment, Figure 4 As shown, the washing device also includes a storage program. The controller 103 controls the washing device to detect whether the washing cavity is connected to the external environment before running the storage program.

[0055] S201, the controller detects whether the washing cavity is connected to the external environment before controlling the washing device to operate

[0056] See the above S101, which will not be repeated here.

[0057] S202. When the controller detects that the washing cavity is not connected to the external environment before the washing equipment is operated, the exhaust device sends a second adjustment instruction to the exhaust device. In response to the second adjustment instruction, the exhaust device adjusts the adjustment valve to open the first air inlet to connect the washing cavity to the external environment.

[0058] The exhaust device 103 responds to the second adjustment instruction to adjust the regulating valve to open the first air inlet to connect the washing chamber 101 with the outside environment. In other words, when it is detected that the washing chamber 101 is not connected with the outside environment, the regulating valve 1021 is adjusted to the second state of opening the first air inlet.

[0059] like Figure 2As shown, the exhaust device 102 responds to the first adjustment instruction and instructs the control motor of the regulating valve 1021 to control the valve plate to rotate clockwise by a preset angle (for example, 70°) until it is adjusted to the following angle: Figure 1 As shown, the first air inlet is opened, and the washing cavity 101 is connected to the external environment.

[0060] In another embodiment, the washing device includes a micro switch, and the micro switch is connected to the regulating valve. The exhaust device 102 adjusts the regulating valve 1021 to open the second air inlet by adjusting the micro switch to the disconnected state. When the exhaust device 102 detects that the micro switch is in the disconnected state, it determines that the regulating valve is in the state as follows: Figure 1 The second state is shown.

[0061] S203: After sending the second adjustment instruction and after a second preset time has passed, the controller detects whether the washing cavity is connected to the external environment?

[0062] After sending the second adjustment instruction and the second preset time has passed, the controller 103 detects again whether the washing chamber 101 is connected to the external environment. The second preset time can be any time set by relevant personnel. For example, the preset time is 70 seconds, and the control motor of the control valve 1021 is controlled to control the valve plate to rotate clockwise by a preset angle to adjust the control valve to the second state, and after 70 seconds from the start of rotation to the timer, it is detected again whether the washing chamber is connected to the external environment by detecting whether the micro switch is in the disconnected state.

[0063] In this embodiment, the first preset time length and the second preset time length are different, which can improve the flexibility of setting the washing device and meet the complex needs of users in using the washing device.

[0064] S204: After sending the second adjustment instruction to the second preset number of times, the controller detects that the washing cavity is not connected to the external environment, and determines that the washing device is faulty.

[0065] After determining that a fault has occurred during the operation and maintenance procedures of the washing equipment, fault intervention measures are taken. The fault intervention measures may include displaying fault information on the equipment, sending alarm prompts, etc., or stopping the operation of the washing equipment, or recording the time and condition of the fault, as well as possible influencing factors, to provide a basis for subsequent analysis.

[0066] In one embodiment, the fault intervention measure taken when determining that the washing equipment has a pre-operation fault is different from the fault intervention measure taken when determining that the washing equipment has an operation maintenance measure fault.

[0067] For example, it is determined that the fault intervention measure taken when the washing equipment fails before operation is to stop the operation of the washing equipment, and the fault information is displayed on the equipment and an alarm prompt is sent; it is determined that the fault intervention measure taken when the washing equipment fails in operation and maintenance measures is to record the time, condition, and possible influencing factors of the fault.

[0068] Because the consequences of a malfunction in the washing program or drying program of the washing equipment are more serious than the consequences of a malfunction in the storage instruction, the fault intervention measures taken by the former are safer than the fault intervention measures taken by the latter, thereby reminding the user that the operating stages of the washing equipment when a malfunction occurs are different.

[0069] S205: The controller determines that the washing cavity is connected to the external environment, and then controls the washing equipment to run a storage program.

[0070] In this embodiment, the washing device includes a storage program. Before the washing device runs the storage program, the controller 103 and the exhaust device 102 perform the following steps: Figure 4 The fault checking method shown is used to detect whether the washing equipment is faulty, and the storage program can be run when the washing cavity is connected to the external environment.

[0071] In another embodiment, the washing device includes a washing program, a drying program and a storage program, and the washing program, the drying program and the storage program are sequentially executed after the washing device is operated. Before the washing device is operated, the controller 103 and the exhaust device 102 execute the following Figure 3 When it is determined that the washing chamber is not connected to the outside environment, the washing device is controlled to perform the washing program and the drying program in sequence. When the controller 103 detects that the washing device meets the preset conditions corresponding to the washing chamber not being connected to the outside environment, the drying program is completed. Before the washing device runs the storage program, the controller 103 and the exhaust device 102 perform the following steps: Figure 4 The steps shown detect whether the washing device is faulty and a storage program can be run when the washing cavity is connected to the external environment.

[0072] In another embodiment, the washing device includes a washing program, a drying program and a storage program, and the washing program, the drying program and the storage program are sequentially executed after the washing device is operated. Before the washing device is operated, the controller 103 and the exhaust device 102 execute the following Figure 3 The steps shown detect whether the washing device is faulty. If it is determined that the washing cavity 101 is always connected to the external environment before the washing device is operated, it is determined that the washing device is faulty.

[0073] In another embodiment, the washing device includes a drying program and a storage program, and the drying program and the storage program are sequentially executed after the washing device is operated. Before the washing device operates the drying program, the controller 103 and the exhaust device 102 execute the following Figure 3 The steps shown detect whether the washing device is faulty. If it is determined that the washing cavity 101 is always connected to the external environment before the washing device runs the drying program, it is determined that the washing device is faulty.

[0074] The washing machine provided by the present application performs a fault detection method before and after operation to detect whether a fault occurs when the washing machine is running a washing program, a drying program, or a storage program. The washing machine provided by the present application has high working reliability and meets the complex use needs of users.

[0075] like Figure 5 The figure is a schematic diagram of the structure of a washing device provided in an embodiment of the present application. Figure 5 The washing device shown includes a controller 203, a washing cavity 201 and an exhaust device 202. The exhaust device 202 includes an exhaust port and a first air inlet. The first air inlet is connected to the washing cavity 201, and the exhaust port is connected to the external environment. A regulating valve is arranged in the exhaust device 202.

[0076] A fan 2022 is provided at the exhaust port side of the exhaust device 202. The fan 2022 is mainly responsible for providing airflow to accelerate the evaporation of surface moisture of the objects to be dried in the washing cavity 201.

[0077] The controller 203 is also used to send a fan information acquisition instruction to the fan when it is detected that the washing cavity is not connected to the external environment. The fan 2022 responds to the fan information acquisition instruction and sends fan information to the controller 203. The controller is also used to receive fan information and determine that the washing device is faulty when it is detected that the fan information does not meet the normal conditions of the fan.

[0078] A temperature and humidity sensor 2023 is provided in the air duct of the exhaust device 202. The temperature and humidity sensor 2023 is a sensor for measuring and monitoring the temperature and humidity in an environment or a specific space, and is usually composed of components such as a temperature and humidity sensor, a signal processing circuit, and a data output interface. In this embodiment, the temperature and humidity sensor is used to obtain temperature and humidity information of the external environment.

[0079] Temperature information is usually measured by a thermistor (such as a thermocouple, a thermistor or a semiconductor sensor) in the temperature and humidity sensor 2023. The above components will change their physical properties (such as resistance value, voltage output, etc.) according to the ambient temperature, and then convert these changes into electrical signals, which are processed by the built-in circuit to obtain accurate temperature values. Humidity information can be obtained through a variety of sensors, such as capacitive humidity sensors, resistive humidity sensors, dew point hygrometers, dry-bulb thermometers, etc.

[0080] The controller 203 is also used to send a temperature and humidity information acquisition instruction to the temperature and humidity sensor 2023. The temperature and humidity sensor 2023 responds to the temperature and humidity information acquisition instruction and sends the temperature and humidity information as the temperature and humidity information of the external environment to the controller 2023. The controller 203 is also used to control the washing device to run a drying program and / or a storage program according to the temperature and humidity information.

[0081] Specifically, it is a schematic diagram of a device fault detection method proposed in the present application, which is executed by the controller 201.

[0082] S301, receiving a start instruction for controlling a washing device to run a drying program and / or a storage program.

[0083] See the above S101, which will not be repeated here.

[0084] S302. Before running the drying program, check whether the washing cavity is connected to the external environment?

[0085] See the above S101, which will not be repeated here.

[0086] S303: Before running the drying program, detect whether the washing cavity is connected to the external environment, and send a first adjustment instruction to the exhaust device.

[0087] See the above S102, which will not be described again here.

[0088] S304. After sending the first adjustment instruction and after a first preset time has passed, detect whether the washing cavity is connected to the external environment?

[0089] See the above S103, which will not be described again here.

[0090] S305. After sending the first adjustment instruction to the first preset number of times, detect whether the washing cavity is still connected to the external environment?

[0091] See the above S104, which will not be described again here.

[0092] S306: When it is determined that the washing cavity is not connected to the external environment, a fan information acquisition instruction is sent to the fan.

[0093] Before running the washing program, it is detected that the washing cavity is not connected to the outside world, and a fan information acquisition instruction is sent to the fan 2022. The fan 2022 responds to the fan information acquisition instruction and sends the fan information to the controller 2022.

[0094] Exemplarily, the fan information may include the working state information of the fan 2022, such as whether the fan 2022 is in an on state or an off state, etc. Exemplarily, the fan information may also include the performance parameters of the fan, such as the running speed or frequency data, wind pressure data, power data and fan data of the fan 2022, etc. The fan information may also include other types of information, which may be set by relevant personnel as needed.

[0095] S307, receiving wind turbine information and detecting whether the wind turbine information meets normal wind turbine conditions.

[0096] When the fan information does not meet the normal conditions of the fan, it is confirmed that the washing equipment is faulty.

[0097] According to the normal conditions of the fan, determine whether the multiple data included in the fan information meet the normal conditions. Exemplarily, the normal conditions of the fan include the ranges when the multiple data are normal. When it is detected that a certain data in the fan information is not within the above range that characterizes that the data is normal, it is determined that the fan information does not meet the preset normal conditions. For example, the fan information includes the performance parameters of the fan, specifically including the operating speed, frequency data, wind pressure data, power data and fan data of the fan. The preset normal conditions include the normal ranges corresponding to the above data respectively. Further, according to the received fan information, it is determined whether the operating speed, frequency data, wind pressure data, power data and fan data are within their respective normal ranges.

[0098] S308: When the fan meets normal conditions, send a temperature and humidity information acquisition instruction to the temperature and humidity sensor.

[0099] The temperature and humidity sensor 2023 responds to the temperature and humidity information acquisition instruction and sends the temperature and humidity information to the controller 203 as the temperature and humidity information of the external environment.

[0100] S309. The controller is also used to control the washing equipment to run a drying program according to the temperature and humidity information.

[0101] In this embodiment, when the regulating valve 2021 is in the first state, that is, the washing chamber 201 is not connected to the external environment, the temperature and humidity information of the exhaust device 202 is obtained through the temperature and humidity sensor 2023. At this time, the temperature and humidity information is equivalent to the temperature and humidity information of the external environment.

[0102] In one embodiment, the controller 203 is also used to send a fan start instruction to the fan 2022 when it detects that the fan information meets the normal conditions of the fan, and to send a temperature and humidity information acquisition instruction to the temperature and humidity sensor 2023 based on a preset frequency within a preset time period after sending the fan start instruction 2022.

[0103] At this time, the fan 2022 responds to the fan start command, and sucks the gas in the washing chamber 201 and discharges it to the outside environment through the exhaust port. In other words, within a preset time period after the fan 2022 sucks the gas in the washing chamber 201 and discharges it to the outside environment through the exhaust port, the temperature and humidity sensor 2023 receives multiple temperature and humidity information acquisition instructions based on a preset frequency, and sends multiple temperature and humidity information to the controller 203 based on the preset frequency. For example, the preset time period is 60 seconds and the preset frequency is 10 seconds, then the temperature and humidity sensor 2023 sends temperature and humidity information to the sensor 203 based on receiving the temperature and humidity information acquisition instruction every 10 seconds.

[0104] The controller 203 is also used to run a drying program and / or a storage program according to the target temperature and humidity information that meets the preset conditions among the multiple temperature and humidity information received within the preset time period. The target temperature and humidity information that meets the preset conditions among the multiple temperature and humidity information, for example, the temperature and humidity that are the minimum values ​​and the humidity that are the minimum values ​​among the multiple temperature and humidity information, respectively, determines the above minimum temperature and the minimum humidity as the target temperature and humidity information. The drying program and / or the storage program are run based on the above target temperature and humidity information to smoothly determine that the washing device completes the drying program and / or the storage program.

[0105] In one embodiment, the exhaust device 202 further includes a second air inlet, which is connected to the external environment, and the regulating valve 2021 is rotatably installed between the first air inlet and the second air inlet. The exhaust device 202 adjusts the regulating valve 2021 in response to the first adjustment instruction to close the first air inlet and open the second air inlet. Figure 5 The temperature and humidity sensor 2023 detects the temperature and humidity information of the external environment in response to the temperature and humidity information acquisition instruction, and sends the temperature and humidity information of the external environment to the controller 203.

[0106] In this embodiment, the controller 203 detects that the washing chamber 201 is connected to the external environment, and sends a first adjustment instruction to the exhaust device 202. In response to the first adjustment instruction, the exhaust device 202 adjusts the regulating valve 2021 to close the first air inlet and open the second air inlet. Here, the second air inlet and the exhaust port in the air duct of the exhaust device 202 are connected to the external environment, and the temperature and humidity information detected by the temperature and humidity sensor 2023 can be used as the temperature and humidity information of the external environment. The controller 203 controls the washing device to run the drying program and / or the storage program based on the above temperature and humidity information as the temperature and humidity information of the external environment.

[0107] S310: After sending the first adjustment instruction to the first preset number of times, if it is detected that the washing chamber is still connected to the external environment, it is determined that the washing device is faulty.

[0108] See the above S104, which will not be described again here.

[0109] The drying principle of the washing equipment is to determine the preset conditions for the completion of drying based on the unconnected cavity and the external environment before operation. The information required for the preset conditions is obtained through a temperature and humidity sensor. After running the drying program, when it is determined that the parameters of the cavity such as temperature and humidity meet the preset conditions, it is determined that the drying of the washing cavity or the storage of the washing cavity is completed.

[0110] Therefore, before controlling the washing device to run the drying program and / or the storage program, the controller obtains the fan information through the fan and / or controls the fan to start and receives the temperature and humidity information of the temperature and humidity sensor to detect whether the washing device is faulty and control the normal operation of the washing device. The washing device proposed in this application can detect faults of the washing device before operation, ensure that the washing device can operate normally such as the washing program, drying program, storage program, etc., and improve the working reliability of the washing device.

[0112] The above disclosure is only the preferred embodiment of the present application, which certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
