Detailed Description
Example 1. A control component is arranged in an electric control system of the household appliance, and the circuit of the control component is connected with an electric control device as a circuit control component. The display control device of the switching key is connected with the electric control device; the switching key switches the electric control system of the machine from an operation mode to a self-checking mode, switches the electric control system including the electric control device and each control component into a standby detection state in abnormal operation, and only the selected control component in the detection state is operable.
First, the electric control device is detected in a self-test mode. A control switch or a relay is arranged in a shunt output circuit of the electric control device, the control switch or the relay is connected with a control component to form a loop and control the on or off circuit mode of the control component, and an output indicator is connected into each output circuit of the electric control device to form an independent detection loop to start the electric control device to run; whether the electric control device is normal or not is judged by monitoring whether the output indicator has different prompting contents and whether the electric control device is in a detection state of being switched on or switched off respectively. The output indicator is either a display window device corresponding to either voltage or current, or an indicator light device, or a prompt buzzer device. As long as the output indicator has response and judges that the output circuit normally has output. And in the same way, the output circuits of the electric control device are respectively and independently detected. The output indicator is not limited to the above-described device, and may be another device reflecting the normality of the shunt output circuit. Through the self-checking of the electric control device, the condition that each branch output circuit of the electric control device is in a normal state is determined.
On the basis, the control switch or the relay arranged on each branch output circuit controls the on and off of the control component circuit connected in each branch output circuit, and self-checking is carried out on the related control component.
The control switch or relay is not arranged in the shunt output circuit of the electric control device, and the shunt output circuit and the control component are detected together when the shunt output circuit is directly connected with a circuit loop formed by the control component.
On the basis, all the control components and related linkage items can be sequentially and automatically selected and detected, the control components to be detected can be selected by using a selection key, and related detection items can be directly selected according to a fault phenomenon. Selecting a control component to be detected from the control components which can be detected by the display control device, and prompting the state of the control component in the operation mode by the display control device; when the circuit of the related control component is started to operate, the control component is in a working state, and the display control device correspondingly gives a prompt corresponding to the fact that the related component is in the working state; when the circuit of the related control component is closed, the control component is in a closed state, and the display control device correspondingly gives a prompt that the corresponding related control component is in the closed state; judging whether the related control components are normal or not according to whether prompts corresponding to different detection states appear or not; and after the self-checking mode is exited, the electric control system restores the running mode.
In this case, the control components of the household appliances include, but are not limited to, a compressor driving circuit device, a current overload protection device, a temperature control device for an air conditioner and a refrigerator, and a refrigerant leakage prevention device for the air conditioner and the refrigerator compressor; the display screen of the television controls the circuit arrangement, and switching power supply and line output device of the television; a drum driving system of the washing machine, a temperature control and heating system of the water heater; the over-burning protection device of microwave oven and electric cooker, the reset device after the overload of the circuit of the household electrical appliance, and the key control components of the household electrical appliance such as the relay, the sensor control device and the like arranged in the electric control circuit. And setting corresponding individual detection items for the control components in the self-test mode. The corresponding display control device correspondingly prompts the working or closing state mode of the control component; such as displaying a hint 1 or 0. Pressing the stop key exits the self-test item of the control component.
In the case, all the electric control components which have great influence on the normal operation of the household appliance machine can be used as the control components to be listed in the self-checking test of the case for detection.
On the basis of the individual self-checking items of each control component, the linkage operation conditions of the corresponding related control components can be further expanded, and the individual self-checking items can also be expanded into the self-checking items of linkage of the control components. In view of the fact that the functions of the related control components of various household appliances are different, and in the actual operation process, the 'operation time' usually exists among the actions of the control components, such as the steps of starting, moving parts, operating, cooling, heating and warming, and the like, so that the 'waiting time' exists when the corresponding control components are detected in a linkage mode. In this embodiment, the operation mode reflects a time period corresponding to a real operation condition of the control component in the detection state. In the linkage detection items of the control components, the 'operation time' existing between actions of the control components is detected so as to truly reflect the 'operation time' existing between the actions of the relevant control components executed by the circuit in the normal operation process of the machine electric control system.
Example 2. On the basis of the embodiment 1, the operation mode is changed into a simulation operation mode; the simulation operation mode refers to an operation mode corresponding to the control component under the actual longer time process condition in the process of simulating and replacing the operation of the machine in the preset time. In order to reduce the corresponding test times and in some cases present during the operation of the household appliance, it is difficult to test the condition according to the actual "running time" of the machine. In general, during the self-checking of the control unit, the actual long time during the operation of the substitute machine is simulated in a preset time period, such as 3-8 seconds, that is, the "operation time" existing between the actions of the substitute control unit in the operation mode is simulated in 3-8 seconds, so as to shorten the corresponding checking time. In particular, in some cases it is difficult to detect the actual "run time" of the machine. In this way, the detected actions of the relevant control components are both clearly distinguished and the "run time" existing between actions in run mode is compressed. The simulation operation mode is particularly suitable for an automatic detection mode which automatically detects all detection items in sequence and outputs detection data in a self-detection mode.
Example 3. On the basis of the above embodiments, a user code encoding system, a data processing and transmitting device and a remote terminal with a user code identification system are also provided. The user code coding system and the data processing and transmitting device are located on the household appliance local machine.
The user code coding system is internally or externally arranged on the local machine and comprises a setting key, a user parameter prompting interface and a user code computing system, wherein user parameters are input through the setting key under the user parameter prompting interface and are used as source data to generate a user code which is only corresponding to the local machine according to the user code computing system, and the user code at least comprises one code of a machine type code, an address code or a communication code; the data transmission device establishes a data intercommunication link with a remote terminal at least through a data transmission mode of one of an internet mode, a data wireless communication transmission mode or a data wired communication transmission mode: or setting a user code, entering a simulation operation mode in a self-checking mode, transmitting automatic detection data corresponding to each control component to the remote terminal, and identifying the user code in the detection data by the remote terminal through the set user code identification system to confirm the identity of the received detection data and then analyzing and judging. The remote code is rejected for detection data for which no user code is set or for which the user code setting is unsatisfactory. On the basis, the remote terminal sends detection conclusion data to the local terminal through one of three data transmission modes by using a local user code. After the user code coding system identifies and confirms the user code of the received detection conclusion data, the data processing and transmitting device of the local machine receives the detection conclusion data and displays the detection conclusion data on the display and control device.
The user code may be one of several types, typically:
user code 1: RO6a2562B214062 denotes: an RO reverse osmosis membrane 6 type water purifier; machine end number a 2562; using area Wuxi city river area street (postcode)
User code 2: 72LW/DH A8561C051082384613 represents: 72LW/DH air conditioner; machine end number a 8561; telephone 82384613 using local Wuxi city (area code)
User code 3: 21N15AAA2864D Mobile phone 13961712345 of No. 987 cell phone in Xincun No. 987 river, street, north of Wuxi city, Jiangsu river

User code 5: 1097A3182 Ejinshuiqi @163.com, which shows: 1097 type gas water heater; machine end number a 3182; using the local tin-free city (mailbox registry), mailbox jingshuiqi @163.com
User code 6: WP750a3062Q1234567890, representing: WP350 type microwave oven; machine end number a 3062; the use region has no tin city (QQ registration place), QQ No. 1234567890
Among the user codes, the patterns of the user codes 1, 2, and 3 are preferable.
Since the corresponding remote terminal knows the model setting series of each household appliance product, only a representative content part needs to be indicated in the model code setting, and the model does not need to be completely indicated to shorten the length of the model code. The letters a are preceded by a model code. Similarly, machine tail numbers, address codes, communication codes, etc. are easily identified. The address code provides as detailed a specific address as directly as possible in view of the need for home repair.
Generally, after the household appliance is installed and powered on, the user code of the household appliance is set through the user code coding system. On the basis, the user code of the local terminal can be sent to the remote terminal for registration through pressing a key. The electric control device starts to operate the monitoring filtering channel after confirming that the corresponding user code is generated.
The internet comprises a wired internet and a wireless internet. Such as including a Wifi network.
Example 4. Example 4 is the most preferred example. On the basis of the above embodiments, a user code encoding system, a data processing and transmitting device and a remote terminal with a user code identification system are also provided. The user code coding system and the data processing and transmitting device are located on the household appliance local machine.
The user code coding system is internally or externally arranged on the local machine and comprises a setting key, a user parameter prompting interface and a user code computing system, wherein user parameters are input through the setting key under the user parameter prompting interface and are used as source data to generate a user code which is only corresponding to the local machine according to the user code computing system, and the user code at least comprises one code of a machine type code, an address code or a communication code; the data processing transmission device establishes data intercommunication link with the remote terminal at least through one data transmission mode of an internet mode, a data wireless communication transmission mode or a data wired communication transmission mode. The remote terminal sends detection request signal data to the user code coding system of the local terminal by using the user code registered by the local terminal. The user code coding system of the local machine identifies the user code of the received request signal data through an additional user code identification device, and prompts the detection request information on the display control device after the user code of the local machine is confirmed. The local user agrees to perform remote detection by pressing keys. The remote terminal enters the local machine after being approved and controls to switch the electric control system of the local machine from the running mode to the self-checking mode and then enters the simulation running mode, each control component is automatically detected in sequence, whether the relevant control component is normal or not is judged according to the detection data corresponding to the state change of the relevant control component, and the running mode of the electric control system of the local machine is recovered after the automatic detection is finished and the self-checking mode is exited. And meanwhile, the detection conclusion data is displayed on a display and control device of the machine.
As another mode of remote detection, after a user code coding system of a local machine is identified and confirmed by an additional user code identification device, a remote terminal directly enters the local machine by using a user code registered by the local machine and controls an electric control system of the local machine to be switched from an operation mode to a self-checking mode, then the electric control system enters a simulation operation mode, each control component is automatically detected in sequence, whether the relevant control component is normal or not is judged according to detection data corresponding to the state change of the relevant control component, and the operation mode of the electric control system of the local machine is recovered after the automatic detection is finished and the self-checking mode is exited. And meanwhile, the detection conclusion data is displayed on a display and control device of the machine.
As an improvement, the remote terminal can periodically set the remote automatic detection of the water purifier in the self-checking mode to enter the simulation operation mode through three modes, and the remote automatic detection is performed once every a period of time.
As a refinement, the user code also comprises a time code, i.e. the user code is a code comprising at least one of a model code or an address code or a communication code or a time code. When the user code set by the user code encoding system further includes a time code, the time code may include a native activation time.
After the machine is installed and powered on, time correction is carried out. The native user code is then set by the user code encoding system. And then the user code including the local starting time is sent to the remote terminal for registration. Correspondingly, the remote terminal automatically sets the starting time of the local machine between 2 and 4 hours in the early morning to start the remote automatic detection of the relevant control components of the local machine in the simulated operation mode in the self-checking mode, thereby avoiding influencing the use of the water purifier by a user as much as possible.
In addition, as a further improvement, the time code may include a purchase date or an activation date of the machine. On the basis, the complete time code is formed by combining the purchase date and the specific time of electrifying the water. The remote terminal determines the warranty period of the machine through the date parameter information of the machine purchasing of the local machine in the user code; and adjusting and determining the specific time range of the remote terminal for implementing remote automatic detection on the machine by the remote terminal according to the specific time parameter information of the electrified water. For the remote automatic detection which is carried out regularly, the specific date of each remote automatic detection can be determined by the purchase date, and on the basis, the specific time for controlling the remote automatic detection can be correspondingly and automatically adjusted by the remote terminal according to the specific time for electrifying water to pass.

In the above embodiments, the internet includes a wired internet and a wireless internet. Such as including a Wifi network.
When the data transmission device of the computer adopts an internet mode, the data transmission device is communicated with the internet through a wired network or a wireless network to realize data link, and the detection data of the computer is sent to the remote terminal through the internet.
In addition, the data transmission device of the local device may transmit the detection data of the local device to the remote terminal in a wireless communication transmission mode.

in the above embodiments, the self-checking mode is a "self-checking" mode in which the machine electronic control system can perform analog detection on a certain control component by a simple key-press auxiliary operation of a machine operator, and the result of the detection judgment is notified to the operator. The biggest difference from the conventional professional maintenance detection is that the self-checking mode does not need an operator to carry out box opening point-by-point detection and observation on parameter values by means of an external detection instrument, and the targeted object is a common user. Usually, the judgment prompt in the self-checking mode is very simple, or only the action process is demonstrated to be clear to an operator. Therefore, professional maintenance personnel can also carry out quick detection through the self-checking mode. On the basis, the machine local machine or the whole remote monitoring system including the machine local machine can automatically complete the detection of a certain control part, and inform an operator of the detection and judgment result, thereby realizing a full-automatic detection mode. It should be noted that even if all the control components of the machine are operational in the self-test mode, the normal operation mode cannot be replaced by operation of the machine in the self-test mode. In other words, the parameter detection performed in the normal operation state of the machine belongs to the "on-line monitoring" in the operation process of the machine, which is different from the "analog" self-detection mode in the present case. After the electric control system enters the self-checking mode, the machine is in a standby state and cannot be started normally. And the machine can be normally started to operate only after the electric control system exits the self-checking mode.
The technical scheme of the application is not only suitable for all white household appliances but also suitable for all black household appliances. Although each product has its own special function and characteristics, the content of the self-checking item of the corresponding control component is accessed, and is not limited to the self-checking item disclosed in the above embodiments.
On the basis of the above embodiments, the protection scope of the present application includes, but is not limited to, the above embodiments. The technical means and principles in the above embodiments may be recombined to derive a new embodiment as required, and the present application also falls within the protection scope of the present application.
