Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
A dehumidifier maintenance method according to an embodiment of the present invention is described below with reference to fig. 1 to 2. It should be noted that the step numbers in the present application, such as S1, S2, S3, S4, and the like, are only for convenience of describing the present solution, and are not to be construed as limiting the order of the steps. That is, for example, the execution order of steps S1, S2, S3, and S4 may be specifically determined according to actual needs, and is not limited to the control in the order of S1 to S4.
As shown in fig. 1, the dehumidifier maintenance method according to the embodiment of the first aspect of the present invention includes the following steps:
s1, obtaining the expected operation time of the dehumidifier according to the design service lives of a plurality of electrical components of the dehumidifier and the weight value of each electrical component in the total operation time of the dehumidifier, wherein the expected operation time is the sum of the products of the design service lives of all the electrical components and the corresponding weight values. In the description of the present invention, "a plurality" means two or more.
Wherein, canThe important electrical components in the dehumidifier are determined according to the specific type of the dehumidifier, and then the design service lives of the electrical components are determined according to the use specifications of the electrical components. The weight value of each electrical component in the total running time of the dehumidifier can be determined according to the aging condition of each electrical component in the running of the dehumidifier. For example, three important electrical components, each having a design life T, may be included in the dehumidifierA、TB、TCThe weight values of the three electrical components are XA、XB、XCIf the expected operation time T of the dehumidifier is equal to TA×XA+TB×XB+TC×XC. Therefore, the expected operation time of the obtained dehumidifier is closer to the actual effective operation time of the dehumidifier.
And S2, recording the actual operation time lengths of the plurality of electrical components, and correcting the actual operation time lengths of the plurality of electrical components to respectively obtain the effective operation time lengths of the plurality of electrical components.
In the step S2, because the loads borne by each electrical component during operation are different, the contribution rate of each electrical component to the operation duration of the dehumidifier is different, and the actual operation duration of each electrical component can be obtained through the a/D conversion between the currents. It should be noted that, the a/D conversion between currents means that the current of each electrical component is converted into a voltage, and the actual operation time length of each electrical component is obtained. It is to be understood that the order of acquiring the actual operation time period of each electrical component is not limited so as to be able to accurately acquire the relevant data.
And S3, multiplying the effective operation time lengths of the plurality of electrical components by the corresponding weight values and summing to obtain the actual operated time length of the dehumidifier.
That is, the effective operating time period of each electrical component obtained in the above step S2 is multiplied by the weight value corresponding to each electrical component in the step S1, and the obtained results are summed up, thereby obtaining the actual operated time period of the dehumidifier.
And S4, comparing the actual running time of the dehumidifier with the expected running time of the dehumidifier to obtain the maintenance information of the dehumidifier.
Specifically, the actual running time of the dehumidifier obtained in the step S3 is compared with the expected running time of the dehumidifier obtained in the step S1, and when the actual running time is shorter than the expected running time, the dehumidifier can continue to work normally; when the actual running time is longer than or equal to the expected running time, the dehumidifier can send out a warning signal to remind a user to replace the dehumidifier, and the user can turn off the dehumidifier at the moment, so that the use safety of the user is ensured.
According to the dehumidifier maintenance method provided by the embodiment of the invention, the expected operation time of the dehumidifier is obtained through the design service lives of the plurality of electrical components and the weight value of each electrical component in the total operation time of the dehumidifier, the actual operation time of the plurality of electrical components is corrected to respectively obtain the effective operation time of the plurality of electrical components, the effective operation time of the plurality of electrical components is multiplied by the corresponding weight values and summed to obtain the actual operated time of the dehumidifier, and finally the actual operated time of the dehumidifier is compared with the expected operation time of the dehumidifier. Therefore, the safe service life of the dehumidifier can be more accurately judged, whether the dehumidifier can work normally can be effectively obtained, the ultra-long-time running and long-time starting running of the dehumidifier are avoided, and the use safety of the dehumidifier is improved.
In some embodiments of the present invention, referring to fig. 1, according to different operation modes of the dehumidifier, the effective operation time periods of the plurality of electrical components are multiplied by the correction coefficients in the corresponding operation modes to obtain the effective operation time periods of the plurality of electrical components, respectively. Because the operating modes of the dehumidifier are different, the loads born by the same electrical components are different, so that the contribution rate of each electrical component to the operating time of the dehumidifier is different, the correction coefficient of each electrical component is respectively given in the different operating modes of the dehumidifier, and the predicted operating time of the dehumidifier can be closer to the actual effective operating time of the dehumidifier by combining with weighted calculation.
Further, the plurality of electrical components include a compressor and an indoor fan, and the operation mode includes a dehumidification mode and a non-dehumidification mode, where it should be explained that the non-dehumidification mode does not refer to all modes except the dehumidification mode, and the non-dehumidification mode refers to a mode in which the dehumidifier does not turn on the dehumidification function. In the dehumidification mode, both the compressor and the indoor fan operate. At this time, the dehumidifier has high power and high current, and has high impact force on electric lines and various internal components, which is not beneficial to prolonging the service life of the dehumidifier, so the correction coefficient in the dehumidification mode can be required as follows: the value of the correction coefficient of the compressor can be equal to 1 or slightly larger than 1 so as to reflect the running time of the compressor or enlarge the running time of the corrected compressor; the value of the correction coefficient of the indoor motor can be slightly larger than 1 so as to enlarge and correct the running time of the indoor motor. In the non-dehumidification mode, the compressor stops working, and the indoor fan works. At the moment, the power of the whole dehumidifier is small, the current is small, and the compressor is not started, so the actual operation time of the compressor is 0, and the value of the correction coefficient of the compressor can be slightly more than 0; the value of the correction coefficient of the indoor motor may be equal to 1 or slightly less than 1, so as to reflect the operated time of the indoor motor or reduce the operated time of the indoor motor. Therefore, the dehumidifier is better in accordance with the actual use situation of the user, and the accuracy of the actual running time of the dehumidifier obtained in the step S3 is ensured.
Furthermore, in the non-dehumidification mode, the actual operation duration of the indoor fan is taken as the operation duration of the compressor, and the operation duration of the compressor is multiplied by the correction coefficient of the compressor in the non-dehumidification mode, so as to obtain the effective operation duration of the compressor. In the non-dehumidification mode, the compressor stops working, the indoor fan works, and the actual running time of the indoor fan is substituted for the running time of the compressor, so that the contribution rate of the compressor to the running time of the dehumidifier in the non-dehumidification mode can be recorded more truly.
In some optional embodiments, the plurality of electrical components further include a water pump, in the dehumidification mode, the compressor, the indoor fan and the water pump all work, at this time, the dehumidifier is in normal operation, and a value of a correction coefficient of the water pump may be slightly greater than 1, so as to enlarge and correct an already-operating time period of the water pump. In the non-dehumidification mode, the compressor stops operating and at least one of the indoor fan and the water pump operates. In other words, in the non-dehumidification mode, the compressor stops working, the indoor fan stops working, and the water pump works normally; or the compressor stops working, the indoor fan normally works, and the water pump stops working; or the compressor can stop working, and the indoor fan and the water pump can work normally. In the non-dehumidification mode, when the water pump works normally, the value of the correction coefficient of the water pump can be equal to 1 or slightly less than 1, so that the running time of the water pump is reflected faithfully or the running time of the water pump is corrected in a shortened mode.
Of course, the mode operation of the dehumidifier may also include other modes, where other modes may be, but are not limited to, a standby mode or a water-full shutdown mode. At this time, important electrical components in the dehumidifier, such as a compressor, an indoor fan, a water pump, etc., are stopped, and thus, are not counted in the calculation of the actual operating time period of the dehumidifier.
As shown in fig. 2, according to some embodiments of the present invention, a switch for controlling whether a plurality of electrical components are powered off is disposed in the dehumidifier, and the expected operation duration is sequentially selected from a 1 st time node, … …, and an nth time node according to a time sequence, where N is a positive integer greater than or equal to 2. It can be understood that the expected operation time T is specifically divided into several parts, which are not set, and can be determined according to the actual requirement of the dehumidifier. For example, N may be set to 2 ≦ N ≦ 5, and N may be 2, 3, 4, 5, avoiding frequent occurrences of maintenance information throughout the expected operational duration of the dehumidification machine. In the following description, N is taken as 3 as an example.
And when the actual running time reaches the ith time node, the dehumidifier sends out first maintenance information, the switch keeps a switch-on state, and i is a positive integer which is more than or equal to 1 and less than N. For example, referring to fig. 2, when the actual running time reaches the 1 st time node, the dehumidifier may send a first maintenance message, such as "E1" word, which does not flicker, to the user through the display screen, and the switch remains on. When the user cuts off power, the first maintenance information disappears. At the moment, a user can select to check the use states of all the electric components in the dehumidifier, and the dehumidifier can be reused after the safety of the electric components is confirmed; or, the first maintenance information can be directly ignored, the power supply of the dehumidifier is switched on again, the dehumidifier is continuously used, and the examination is carried out when the dehumidifier is available. Here, it should be noted that although the first maintenance information disappears when the dehumidifier turns off the power supply, the data of the actual operating time period of the dehumidifier is not cleared. Alternatively, the switch may be a relay, but is not limited thereto.
Similarly, when the actual running time reaches the 2 nd time node, the dehumidifier can send a first maintenance message which does not flicker to the user through the display screen, such as the word "E1", and meanwhile, the switch, such as the relay, keeps the on state. When the user cuts off power, the first maintenance information disappears. At the moment, a user can select to check the use states of all the electric components in the dehumidifier, and the dehumidifier can be reused after the safety of the electric components is confirmed; or, the first maintenance information can be directly ignored, the power supply of the dehumidifier is switched on again, the dehumidifier is continuously used, and the examination is carried out when the dehumidifier is available. The data of the actual running time of the dehumidifier still cannot be cleared.
When the actual running time reaches the Nth time node, the actual running time reaches the expected running time, and the dehumidifier sends the second maintenance information for a preset time, the switch such as a relay is turned off to cut off the power of the plurality of electrical components. For example, referring to fig. 2, when the actual running time reaches the 3 rd time node, the dehumidifier may send a flashing second maintenance message, for example, the word "E1", to the user through the display screen, and continuously flash for 10 seconds, and at the same time, the switch, for example, the relay, disconnects the plurality of electrical components, and at this time, the dehumidifier may not be normally used.
Further, when the actual running time reaches the ith time node, the working electric component stops working, the dehumidifier sends out first maintenance information, and the switch keeps on state. When the dehumidifier is in a dehumidification mode, the compressor, the indoor motor and the water pump receive a 'turn-off' instruction at the same time, and the compressor, the indoor motor and the water pump stop working at the moment. When the dehumidifier is in a non-dehumidification mode, one of the indoor motor and the water pump which is in a working state receives a 'turn-off' instruction. At the moment, the actual running time of the dehumidifier does not reach the expected running time, and the purpose that the dehumidifier sends the first maintenance information is to remind a user to perform maintenance inspection on the dehumidifier, so that the use safety of the dehumidifier is ensured. And the power supply of the dehumidifier is switched on again, the dehumidifier can be continuously used, and meanwhile, the data of the practical running time of the dehumidifier cannot be cleared.
And when the actual running time reaches the Nth time node, the actual running time reaches the expected running time, the working electrical components stop working, and the switch is switched off to cut off the plurality of electrical components after the dehumidifier sends the second maintenance information for the preset time. At this time, the switch, such as a relay, disconnects a plurality of electrical components, and at this time, the dehumidifier cannot be normally used, and a user needs to replace the dehumidifier.
According to some embodiments of the present invention, as shown in fig. 2, after the dehumidifier issues the second maintenance warning message and the switch is turned off to power off the plurality of electrical components, the method further includes:
and clearing the forced disconnection instruction of the switch when the actual running time reaches the Nth time node. The user can contact with after-sales personnel to overhaul the dehumidifier, and confirm whether the script command of forcibly executing the power-off action on the switch can be brushed off, and when the forced-off command of the switch can be cleared, the dehumidifier can be recovered to be normally used. If the forced disconnection instruction of the switch cannot be cleared, the dehumidifier should be abandoned and a new dehumidifier should be bought again in order to ensure the use safety of the user.
Further, after the forced disconnection instruction of the clearing switch, the dehumidifier is started every time, and the dehumidifier sends out third dimension protection information. Specifically, when the dehumidifier is started and any one of the electrical components is started, the dehumidifier sends out third maintenance information through the display screen, but other functions are invalid (for example, the switch forcibly turns off the function of the electrical component). The third maintenance information can be cleared by one key when the dehumidifier is started, but when the dehumidifier is started next time and any electric part is started, the dehumidifier can send the third maintenance information through the display screen again to remind a user to replace the dehumidifier.
The dehumidifier maintenance device (not shown) according to the second aspect of the present invention comprises a storage module, a monitoring module, a judging module and a maintenance module.
The storage module is used for obtaining the expected operation time of the dehumidifier according to the design service lives of a plurality of electrical components of the dehumidifier and the weight value of each electrical component in the total operation time of the dehumidifier, and the expected operation time is the sum of the products of the design service lives of all the electrical components and the corresponding weight values. That is to say, the storage module is used for storing the design service life of each electrical component, the weight value of each electrical component in the total running time of the dehumidifier, the correction coefficient of each electrical component in different running modes and the expected running time of the dehumidifier.
The monitoring module is used for recording the actual operation duration of the plurality of electrical components and correcting the actual operation duration of the plurality of electrical components so as to respectively obtain the effective operation duration of the plurality of electrical components, and the effective operation duration of each electrical component can adopt an accumulation principle. And multiplying the effective running time of the plurality of electrical components by the corresponding weight values and summing to obtain the actual running time of the dehumidifier, wherein the actual running time of the dehumidifier can also adopt an accumulation principle.
The judgment module is used for comparing the actual running time of the dehumidifier with the expected running time of the dehumidifier. The judging module comprises an operation mode judging module and an actual operation time length judging module. The operation mode judging module can acquire a signal according to the operation mode selected by the user and judge whether the dehumidifier is in a dehumidification mode or a non-dehumidification mode. The actual running time length judging module compares the acquired actual running time length T with the pre-written expected running time length T, and if T respectively reaches T1, T2 or T3, the actual running time length judging module sends a corresponding instruction to the maintenance module, and the maintenance information can be cleared; when T is greater than T3 and the dehumidifier continues to operate, the actual operating time length judging module only sends a corresponding instruction to the maintenance module when the dehumidifier is started and any electrical component is started each time.
The maintenance module is used for obtaining maintenance information of the dehumidifier. Specifically, the maintenance module is configured to receive an instruction of the actual operation duration determination module, and perform a related action: when the maintenance module judges that T is T1 or T is T2, the maintenance module sends first maintenance information which does not flicker to a user through a display screen, for example, the word 'E1', and when the user cuts off the power supply, the first maintenance information disappears. At the moment, a user can select to check the use states of all the electric components in the dehumidifier, and after the safety is confirmed, the power supply is switched on again to use the dehumidifier; or directly neglecting the first maintenance information, directly switching on the power supply again, continuously using the dehumidifier, and checking when the dehumidifier is available. When the actual running time T reaches the expected running time T3, the dehumidifier sends flickering second maintenance information to the user through the display screen, for example, the character of 'E1', continuously flickers for 10 seconds, and then the dehumidifier is turned off through the control switch to forcibly execute a 'power-off' action, so that the electric components stop working, and at this time, the user cannot normally use the dehumidifier.
At this time, the user has two ways to quit the maintenance module: firstly, after-sales personnel are contacted for maintenance, whether a script command of forcibly executing a power-off action on a switch can be brushed off is determined, and the dehumidifier is enabled to be recovered to be normally used; and secondly, in order to ensure the use safety, the dehumidifier is abandoned and a new dehumidifier is bought again.
When the script command of 'switch forced execution' power-off 'action' is brushed off, the maintenance module receives the instruction of the actual running time length judgment module, only when the dehumidifier is started and any electric component is started every time, namely when T is larger than T3, the maintenance module sends third maintenance information to remind a user of replacing the dehumidifier as soon as possible, meanwhile, the third maintenance information can be cleared by one key when the dehumidifier is started, and when the dehumidifier is started next time and any electric component is started, the maintenance module sends the same third maintenance information again to remind the user.
