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.
The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
A maintenance method of an air conditioner according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1 to 2.
As shown in fig. 1 and 2, a maintenance method of an air conditioner according to an embodiment of a first aspect of the present invention includes the steps of:
obtaining the expected operation time length T of the air conditioner according to the design service lives of a plurality of electrical components of the air conditioner and the weight value of each electrical component in the total operation time length of the air conditioner, wherein the expected operation time length T is the sum of the products of the design service lives of all the electrical components and the corresponding weight values;
the method comprises the steps of firstly determining the type of the electric components in the air conditioner, wherein the electric components can comprise a compressor, an indoor motor and an outdoor motor according to the type of the electric components, but not limited to the type of the electric components, determining the design service life of each electric component according to the type of each electric component and the specification of each electric component, then determining the weight value of each electric component in the total operation time of the air conditioner by considering the operation condition and the aging condition of each electric component, and combining the weight value of each electric component and the design service life to obtain the expected operation time T of the air conditioner.
Recording the actual operation time lengths of the plurality of electrical components, multiplying the actual operation time lengths of the plurality of electrical components by the corresponding weight values and summing to obtain the actual operated time length t of the air conditioner;
when the air conditioner operates, each electrical component in the operated air conditioner can be detected, the actual operation time length of each electrical component is obtained, and the actual operation time length and the weighted value of the corresponding electrical component are weighted and summed, so that the actual operation time length t of the air conditioner is obtained.
And comparing the actual running time T of the air conditioner with the expected running time T of the air conditioner to obtain the maintenance information of the air conditioner. For example, after the actual running time T of the air conditioner is compared with the expected running time T of the air conditioner, when the actual running time T is less than the expected running time T, the air conditioner can continue to work normally; when the actual running time T is more than or equal to the expected running time T, all electrical components in the air conditioner can be powered off to prompt a user that the safety of the air conditioner is low, and meanwhile, a warning signal can be sent out to remind the user to replace the air conditioner.
According to the maintenance method of the air conditioner, the expected operation time length of the air conditioner 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 length of the air conditioner, the actual operation time lengths of the plurality of electrical components are multiplied by the corresponding weight values and summed to obtain the actual operation time length of the air conditioner, and finally the actual operation time length of the air conditioner is compared with the expected operation time length of the air conditioner to obtain the maintenance information of the air conditioner. Therefore, the safe service life of the air conditioner can be more accurately judged, whether the air conditioner can work normally can be effectively obtained, the air conditioner can be effectively prevented from running for a long time, and the use safety of the air conditioner is improved.
According to some embodiments of the invention, the plurality of electrical components includes a compressor, an indoor motor, and an outdoor motor. The compressor, the indoor motor and the outdoor motor are important electrical components in the air conditioner, the actual running time T and the expected running time T of the air conditioner are calculated according to the design service lives and the weighted values of the three electrical components, so that the actual running time T and the expected running time T of the air conditioner can be basically close to the actual running time and the actual expected running time of the air conditioner, and the safe service life of the air conditioner can be judged more accurately while the convenience in calculation is guaranteed.
According to some embodiments of the present invention, a switch for controlling whether a plurality of electrical components are powered off is provided in the air conditioner;
and sequentially selecting a 1 st time node, … … and an Nth time node according to the expected running time T in the time sequence, wherein N is a positive integer greater than or equal to 2.
It is understood that the expected operation time period T is specifically divided into several parts, which are not set, and can be determined according to the actual demand of the air conditioner. For example, N can be set to be 2 or more and 5 or less, N can be 2, 3, 4 or 5, and thus the range of N is set between 2 and 5, which not only can avoid the overlarge judgment range caused by the undersize value of N, thereby avoiding the problem of larger potential safety hazard of the air conditioner caused by the low sensitivity of the user to the prompting signal sent by the air conditioner, but also can avoid the overlarge time node caused by the overlarge value of N, thereby avoiding the trouble of the user caused by frequent occurrence of maintenance information in the whole expected running time of the air conditioner. In the following description, N is taken as 3 as an example.
When the actual running time t reaches the ith time node, the air conditioner sends out first maintenance information, the switch keeps the on state, and i is a positive integer which is greater than or equal to 1 and smaller than N. For example, referring to fig. 2, when the actual running time reaches the 1 st time node, the air conditioner may issue a warning for regular maintenance (i.e., first maintenance information) to the user through the display screen, for example, in the word "E1", and the warning word disappears when the user presses one key, and the switch remains on. At the moment, the user can select to check the use state of each electrical component in the air conditioner, and the air conditioner can be reused after the safety of the electrical components is confirmed; or, the first maintenance information can be directly ignored, the power supply of the air conditioner is switched on again, the air conditioner is continuously used, and the check is carried out when the air conditioner is available. Here, it should be noted that although the first maintenance information disappears when the air conditioner is powered off, the data of the actual operating time period of the air conditioner is not cleared.
Similarly, when the actual running time reaches the 2 nd time node, the air conditioner may issue a warning of regular maintenance (i.e., first maintenance information) to the user through the display screen, for example, in the word "E1", while the switch remains on. At the moment, the user can select to check the use state of each electrical component in the air conditioner, and the air conditioner can be reused after the safety of the electrical components is confirmed; or, the first maintenance information can be directly ignored, the power supply of the air conditioner is switched on again, the air conditioner is continuously used, and the check is carried out when the air conditioner is available. It should be noted that the data of the actual running time of the air conditioner is not cleared yet.
And when the actual running time T reaches the Nth time node, the actual running time T reaches the expected running time T, and the switch is switched off to cut off the plurality of electrical components after the air conditioner sends the second maintenance information for the preset time.
And when the actual running time reaches the Nth time node, the actual running time reaches the expected running time, the air conditioner sends out second maintenance information, and the switch is switched 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 air conditioner may send a second maintenance message, for example, the word "E1", to the user through the display screen, and the switch turns off the plurality of electrical components, so that the air conditioner may not be normally used.
According to some embodiments of the present invention, after the air conditioner issues the second maintenance message and the switch is opened to power off the plurality of electrical components, the method further comprises:
and clearing the forced disconnection instruction of the switch when the actual running time t reaches the Nth time node. The user can contact after-sales personnel to overhaul the air conditioner, confirms whether the switch can be closed, and when the switch can be closed, the air conditioner can be recovered to be normally used. If the switch can not be closed, the air conditioner is abandoned and a new air conditioner is bought again in order to ensure the use safety of the user.
And the air conditioner sends out third maintenance information each time the air conditioner is started and at least one electric component is started. Specifically, when the air conditioner is started and any important electrical component is started, the air conditioner 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) so as to remind a user to replace the air conditioner with a new one as soon as possible. The third protection information can be cleared by one key when the air conditioner is started, but when the air conditioner is started next time and any important electrical component is started, the air conditioner can send the third protection information through the display screen again to remind a user to replace the air conditioner.
Optionally, the switch is a safety solenoid valve, but is not limited thereto. The safety electromagnetic valve can be connected with a live wire of a power line. Before the actual running time T of the air conditioner reaches the expected running time T of the air conditioner, the safety electromagnetic valve is always in a closed state, and the normal running of the air conditioner is in an out-of-control state. At this time, the electric components in the air conditioner can be safely operated. When the actual running time T reaches the expected running time T, the safety electromagnetic valve is disconnected, the air conditioner cannot be normally used at the moment so as to remind a user to check the air conditioner, the use safety and the use reliability of the air conditioner are improved, and meanwhile, the switch can be disconnected when the electrical component is in short circuit so as to increase the safety of the electrical component.
A method for maintaining an air conditioner according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 2.
Firstly, the types of the electrical components in the air conditioner are determined, the air conditioner can be divided into a compressor, an indoor motor and an outdoor motor according to the types of the electrical components, but the air conditioner is not limited to the three types, the design service life of each electrical component can be determined according to the type and the specification of each important electrical component, then the weight value of each electrical component is determined by considering the running condition and the aging condition of each electrical component, and the expected running time length T of the air conditioner can be obtained by combining the weight value and the design service life of each electrical component. When the air conditioner is started to operate, the operated air conditioner can be detected, the actual operation time length of each electrical component is obtained, and the actual operation time length is combined with the weight value of the electrical component, so that the actual operation time length t of the air conditioner is obtained.
As shown in fig. 2, T includes N stages in chronological order, for example, N is 3, so that the expected operation time period T of the air conditioner is divided into 3 stages, i.e., T1, T2, and T3, i.e., T1 is 1/3T, i.e., T2 is 2/3T, and i.e., T3 is T, and T is compared with Ti, and a prompt is given according to the comparison result to facilitate the user's determination on the safety of the air conditioner.
When T is less than T1(T1 ═ 1/3T), continuing to operate the accumulated actual operated time T of the air conditioner;
when T is greater than or equal to T1 and less than T2(T1 is 1/3T, and T2 is 2/3T), the air conditioner sends first maintenance information, which indicates that the safety of the air conditioner begins to be reduced, a user can perform operation according to the sent warning prompt, such as clearing the first maintenance information option or performing a power-off maintenance option, and the user can select the first maintenance information option according to the requirement, such as the user does not have time to perform maintenance temporarily, or the first maintenance information option can be selected to be cleared when the service condition of the air conditioner is considered to be good; after the option of clearing the first maintenance information is selected, the air conditioner continues to operate and the actual operating time t of the air conditioner is accumulated; when the user needs to overhaul, the power-off overhaul option can be selected, after the power-off overhaul option is selected, the air conditioner is powered off so that the user can overhaul the air conditioner, after the air conditioner is overhauled, the air conditioner is restarted, and then the actual running time of the air conditioner continues to accumulate.
When T is greater than or equal to T2 and less than T3(T2 is 2/3T, T3 is T), the air conditioner sends first maintenance information, which indicates that the safety of the air conditioner is slightly low, a user can operate according to the sent first maintenance information, such as clearing the first maintenance information option or performing a power-off maintenance option, and the user can select according to needs, such as the user does not have time to perform maintenance temporarily, or the user can select to clear the first maintenance information option when the service condition of the air conditioner is considered to be good; after the option of clearing the first maintenance information is selected, the air conditioner continues to operate and the actual operating time t of the air conditioner is accumulated; when the user needs to overhaul, the power-off overhaul option can be selected, after the power-off overhaul option is selected, the air conditioner is powered off so that the user can overhaul the air conditioner, after the air conditioner is overhauled, the air conditioner is restarted, and then the actual running time of the air conditioner continues to accumulate.
When T is equal to T3(T3 ═ T), the air conditioner sends out second maintenance information, which indicates that the safety of the air conditioner is low, the air conditioner stops working and is powered off forcibly, and a user can operate according to the sent out second maintenance information; if the air conditioner is selected to be maintained, after-sales personnel needing to be connected with the air conditioner carry out maintenance, and the air conditioner can be operated again after the after-sales personnel carry out maintenance; if the air conditioner is selected to be replaced, the use safety of the air conditioner is improved.
When T is larger than T3, the user can be considered to use the air conditioner in emergency, and at the moment, third maintenance information is sent out when the air conditioner is used each time to prompt that the safety of the air conditioner used by the user is too low, so that the user can select to replace the air conditioner as soon as possible.
As shown in fig. 2, the air conditioner maintenance apparatus according to the embodiment of the second aspect of the present invention includes a storage module, a monitoring module, a determining module and a maintenance module.
The storage module is used for obtaining the expected operation time length T of the air conditioner according to the design service lives of a plurality of electrical components of the air conditioner and the weight value of each electrical component in the total operation time length of the air conditioner, and the expected operation time length T is the sum of the products of the design service lives of all the electrical components and the corresponding weight values.
The storage module can record the actual running time t of the air conditioner and cannot stop accumulating along with the closing of the air conditioner; meanwhile, after the weight values of all electrical components in the air conditioner are judged, the expected operation time length T of the air conditioner is recorded into the storage module, the actual operation time length T and the expected operation time length T in the air conditioner can be better stored, and data loss after the air conditioner is powered off is prevented.
The monitoring module is used for recording the actual operation time lengths of the plurality of electrical components, multiplying the actual operation time lengths of the plurality of electrical components by the corresponding weight values and summing the multiplied actual operation time lengths to obtain the actual operated time length t of the air conditioner. The monitoring module can automatically monitor the operation condition and the operation time of each electrical component after the air conditioner operates, the operation condition and the operation time are combined with the weight value to obtain the actual operation time t of the air conditioner, the t is input into the storage module, meanwhile, the operation condition of each electrical component can be monitored, and when the electrical components are damaged, a signal can be fed back to the air conditioner and a prompt alarm is sent out.
The judging module is used for comparing the actual running time T of the air conditioner with the expected running time T of the air conditioner. The judging module can compare the size relationship between the actual running time T of the air conditioner and the expected running time T of the air conditioner; specifically, the judging module can compare the actual running time T of the air conditioner with the size relationship between T1 and TN, so that a feedback signal can be sent to the air conditioner according to the comparison result, warning information can be sent to the air conditioner, and when second warning information needs to be sent to the air conditioner, a signal can be also fed back to the safety maintenance module.
The maintenance module is used for obtaining the maintenance information of the air conditioner. The safety electromagnetic valve can be used as a maintenance module, and when the maintenance module receives a signal from the judgment module, the safety electromagnetic valve can be disconnected, so that the air conditioner is powered off forcibly, the air conditioner cannot be used continuously, and a user is forced to repair or replace the air conditioner. It should be noted that the safety electromagnetic valve can be installed on the live wire connecting the air conditioner and the power supply to have a better power-off effect, and when the feedback signal is not received, the safety electromagnetic valve is in a closed state.
Therefore, according to the maintenance device of the air conditioner, the service condition of the air conditioner can be monitored, the actual running time T of the air conditioner is measured after the expected running time T of the air conditioner is determined, the actual running time T is compared with the expected running time T, different warning information is sent out on the air conditioner according to the comparison result to remind a user of the safety condition of the air conditioner, and the user can maintain, detect or replace the air conditioner according to the safety condition of the air conditioner to guarantee the service safety of the air conditioner.
According to the air conditioner of the embodiment of the third aspect of the present invention, the maintenance method of the air conditioner according to the embodiment of the first aspect of the present invention described above is adopted.
According to the air conditioner provided by the embodiment of the invention, by adopting the air conditioner maintenance method provided by the embodiment of the first aspect of the invention, the safe service life of the air conditioner can be more accurately judged, the use safety of the air conditioner is improved, and the cost is reduced.
