Fall under the scope of the present invention.
Below with reference to coming exemplified by the process of the detection control method of the indoor apparatus of air conditioner operation present invention to inspection of the invention
Control method is surveyed to be described in detail.Referring next to Fig. 2, the figure be the present invention the detection control method for air-conditioning the step of
Flow chart.As shown in Fig. 2, the detection control method mainly includes the following steps that：
S101：Obtain the time that air-conditioning exits heating mode；
S102：Judge that air-conditioning exits whether time of heating mode is more than the scheduled time；If it is not, then step is performed again
Rapid S101；If it is, perform step S103；
S103：Detect the temperature near electric heater unit；
S104：Judge whether the temperature near electric heater unit is more than the first predetermined temperature；If it is not, then perform step
S105；If it is, perform step S106；
S105：The power supply of the air-conditioning is not cut off；
S106：Obtain ambient temperature；
S107：Calculate the difference of the temperature and ambient temperature near electric heater unit；
S108：Judge whether the difference is more than the second predetermined temperature；If it is not, then perform step S105；If so,
Then perform step S109；
S109：Failure linkage signal is sent to executive component；
S110：The power supply of air-conditioning is cut off by executive component.
Specifically, as shown in Fig. 2, first in step S101, the time that the air-conditioning exits heating mode is obtained, so as to
The control device can whether normal power down makes accurate judgement to electric heater unit 11.It is understood that in the sky
After tune exits heating mode, if electric heater unit 11 can normal power down, within a period of time, electric heater unit 11 or have
There is higher residual temperature.Therefore, after the air-conditioning exits heating mode, if the first temperature sensor 16 at once fills electrical heating
Put the temperature near 11 to measure, the residual temperature of electric heater unit 11 will influence measurement result at this time, so as to cause mistake
Judging result.In other words, the first temperature sensor 16 need over time again to the temperature near electric heater unit 11 into
Row measurement, so that the temperature measured at this time can accurately reflect the open and-shut mode of electric heater unit 11, so as to strengthen the detection control
The reliability of method processed.It should be noted that the heating mode described in this preferred embodiment be not limited only to it is now air-conditioned
Heating mode, specifically, as long as when the air-conditioning is in the pattern, electric heater unit 11 is in "on" position, and the pattern is just
It is the heating mode described in this preferred embodiment.
Then in step s 102, by the control device judge the air-conditioning exit heating mode time it is whether big
In the scheduled time.In other words, the air-conditioning needs in the given time fully heat dissipation, then, then makes the control device to electricity
Temperature near heating unit 11 measures, so that the temperature can accurately reflect the opening and closing device of electric heater unit 11.Can
With understanding, since different air-conditionings have different built-in component and structure, the heat dissipation effect of different air-conditionings also differs
Sample；Technical staff was needed according to the heat dissipation effect of the air-conditioning come the sets itself scheduled time, so that the air-conditioning can be pre-
Fix time it is interior fully heat dissipation, so that the accuracy of measurement data be effectively ensured.
Further, in the judgement of step S102, if the time that the air-conditioning exits heating mode is less than or equal to
The scheduled time, then illustrate that the air-conditioning is also no and sufficiently radiated；At this time, step S101 is continued to execute, so as to when institute
Air-conditioning is stated again measure the temperature near electric heater unit 11 after fully radiating.Meanwhile if the air-conditioning exits
The time of heating mode is more than the scheduled time, then illustrates that the air-conditioning fully radiates, and the control device can start to obtain
The temperature near electric heater unit 11 is taken, and accurate judgement is carried out to the open and-shut mode of electric heater unit 11 according to the temperature.
Therefore, in the judgement of step S102, if the time that the air-conditioning exits heating mode is more than the scheduled time, step is performed
S103, i.e., by the temperature near the first temperature sensor 16 detection electric heater unit 11, effectively to judge electric heater unit
11 open and-shut mode.
Further, in step S104, judge whether is temperature near electric heater unit 11 by the control device
More than the first predetermined temperature；If the temperature near electric heater unit 11 is less than or equal to first predetermined temperature, illustrate
Relay 13 normally disconnects, meanwhile, the also normal switching-off of electric heater unit 11.It is understood that only when electricity adds
11 normal switching-off of thermal, and the air-conditioning in the given time fully radiate in the case of, near electric heater unit 11
Temperature can be just reduced under the first predetermined temperature.At this time, step S105 is performed, i.e., does not cut off the power supply of the air-conditioning, makes institute
State the operation program normal switching-off of air-conditioning.In addition, it will be appreciated to those of skill in the art that preferably, described first
Predetermined temperature is set as 28 DEG C；Certainly, technical staff can also according to actual use situation sets itself described in the first pre- constant temperature
Degree.
In addition, in step S104, if the temperature near electric heater unit 11 is more than first predetermined temperature, say
Bright relay 13 is possible to not disconnect normally, and therefore, electric heater unit 11 may also not have normal switching-off.At this time, in order into
One step ensures the reliability of judging result, performs step S106, i.e., described control device is obtained by second temperature sensor 17
Ambient temperature.It is appreciated that when, after the scheduled time, if the temperature near electric heater unit 11 is also greater than institute
State the first predetermined temperature and then there may exist two kinds of situations：A kind of situation is, the normal switching-off of electric heater unit 11, still,
Ambient temperature is also very high at this time, and the air-conditioning can not fully radiate in the given time, therefore cause electric heater unit 11
Neighbouring temperature is also greater than first predetermined temperature；Another situation is that electric heater unit 11 does not have normal switching-off, because
This, is although the temperature of external environment is relatively low at this time, under the heat effect of electric heater unit 11, after the scheduled time,
Temperature near electric heater unit 11 still can be more than first predetermined temperature.
Further, after obtaining ambient temperature in step s 106, step S107 is performed, i.e., is filled by the control
Put the difference for calculating temperature and ambient temperature near electric heater unit 11.It is understood that electric heater unit 11 is attached
Near temperature and the difference of ambient temperature are bigger, and the heat exchange rate between the air-conditioning and external environment is also faster, i.e. institute
The radiating rate for stating air-conditioning is also faster；In other words, the difference of the temperature near electric heater unit 11 and ambient temperature is got over
Small, the heat exchange rate between the air-conditioning and external environment is also slower, i.e., the radiating rate of described air-conditioning is also slower.Further
Ground, in the case that the temperature near electric heater unit 11 is more than first predetermined temperature, if near electric heater unit 11
Temperature and ambient temperature also there are larger difference, then illustrate that electric heater unit 11 does not have normal switching-off；Meanwhile in electricity
In the case that temperature near heating unit 11 is more than first predetermined temperature, if temperature near electric heater unit 11 with
Ambient temperature only exists less difference, then illustrates the normal switching-off of electric heater unit 11.
Further, in step S108, judge whether the difference is more than the second pre- constant temperature by the control device
Degree；At this time, if the difference is less than or equal to second predetermined temperature, illustrate that relay 13 normally disconnects, together
When, the also normal switching-off of electric heater unit 11.In the case, the air-conditioning is performed step S105, i.e., do not cut off described
The power supply of air-conditioning, makes the operation program normal switching-off of the air-conditioning.In addition, it will be appreciated to those of skill in the art that
Preferably, second predetermined temperature is set as 20 DEG C；Certainly, technical staff can also be according to actual use situation sets itself
Second predetermined temperature.
In addition, in step S108, if the difference is more than second predetermined temperature, illustrate electric heater unit 11
Neighbouring temperature, there are larger difference, has faster at this time, between the air-conditioning and external environment with ambient temperature
Heat exchange rate, i.e., the radiating rate of described air-conditioning are also very fast；Under the premise of herein, the difference is also greater than the described second pre- constant temperature
Degree, then illustrate that the relay 13 of the air-conditioning is not normal and disconnect, therefore, electric heater unit 11 does not have normal switching-off yet.This
When, step S109 is performed, even if the control device sends failure linkage signal to failure linkage executive component 14, so that
Failure linkage executive component 14 is able to carry out step S110.In step s 110, failure linkage executive component 14 can cut off institute
State the power supply of air-conditioning so that the power supply of electric heater unit 11 is cut off by force so that effectively avoid electric heater unit 11 it is non-can
The problem of opening for a long time under control state and cause the indoor unit internal temperature of the air-conditioning excessive, so as to the indoor unit
Inner body plays more preferable protective effect, and then dramatically improves the security of the air-conditioning.
Finally it should be noted that above-described embodiment is the preferred embodiments of the invention, it is not intended as to the present invention
The limitation of protection domain.Those skilled in the art can be properly added or delete as needed one when actually using the present invention
Part steps, or exchange the order between different step.This basic principle changed not departing from the present invention, belongs to this
