Detailed description of the invention
Fig. 1 is the flow chart of the operating process for the control method that the present invention prevents abnormal sound.
Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
What the present invention provided a kind of air conditioner prevents abnormal sound control method, and it is different that Fig. 1 is that air conditioner according to the present invention prevents
The operating process flow chart for ringing control method, as shown in Figure 1, this method includes following content:
Firstly, heating mode is transferred to afterwards for a period of time in air conditioner operation refrigeration mode or dehumidification mode, the heating mode
The inner blower operating of lower air-conditioning is without entering the auxiliary heat pattern of electricity；Obtain the cooler compressor under refrigeration mode or dehumidification mode
Continuous operation time, when being transferred to heating mode obtain electric heating tube humidity value；
By the compressor continuous operation time and compressor preset time T 1, the humidity value and default humidity critical point
H is compared respectively, if meeting OnNow condition, the auxiliary heat pattern of electricity for controlling the air conditioner is opened immediately；
The OnNow condition includes the compressor continuous operation time < T1, and the humidity of the electric heating tube
Value < H, it is preferable that T1 10min, H are the critical point to form droplet.Therefore, it under instant entry condition, refrigeration mode or removes
The compressor continuous operation time of wet model is smaller, and the humidity value of electric heating tube is less than H, shows the surface of electric heating tube at this time
Therefore basic no generation condensed water directly initiates the auxiliary heat pattern of electricity, air conditioner in the case where meeting OnNow condition
Abnormal sound will not be generated.
Secondly, controlling the auxiliary heat pattern delayed start-up of the electricity if being unsatisfactory for the OnNow condition.Delayed start-up
Main purpose is to utilize the blowing effect of inner blower by electric heating tube surface in a heating mode before the auxiliary heat pattern starting of electricity
Water evaporation is condensed, abnormal sound will not be generated to air conditioner after guaranteeing the auxiliary heat pattern starting of electricity.
Specifically it is divided into two kinds of situations:
(1) as the compressor continuous operation time < T1, and when the humidity value >=H, the air conditioner enters delay
State, the delay state include: the inner blower starting operation of the air conditioner under heating mode.Such case, compressor connect
The continuous duration of runs is shorter but humidity value >=H, shows that the surface of electric heating tube at this time produces a small amount of condensed water, therefore, obtains
The runing time > inner blower of the runing time of the inner blower of the air conditioner under heating mode, the inner blower of the air conditioner is pre-
If after time T2, the air conditioner delay state terminates, the auxiliary heat pattern of electricity of the air conditioner is opened.Preferably, T2 5min,
After running T2 by inner blower at this time, the condensed water on electric heating tube surface all substantially can be dried up into evaporation,
(2) as the compressor continuous operation time >=T1, and when the humidity value > H, the air conditioner enters delay
State, the delay state include: the inner blower starting operation of the air conditioner under heating mode.Such case, compressor connect
The continuous duration of runs is longer and humidity value > H, shows that the surface of electric heating tube at this time produces a large amount of condensed water, therefore, obtains
The runing time of the inner blower of the air conditioner under heating mode, when the runing time > inner blower of the inner blower of the air conditioner
After preset time T 2, the real-time wet angle value of the electric heating tube at this time is obtained, if the real-time wet angle value < H, the air conditioner
Delay state terminates, and the auxiliary heat pattern of electricity of the air conditioner is opened.
Preferably, if real-time wet angle value >=H at this time, illustrate the T2 of inner blower operation at this time not by the solidifying of electric heating tube surface
Whole evaporations are born water, then inner blower constantly obtains the real-time wet angle value of the electric heating tube in a heating mode, described in acquisition
The time interval of real-time wet angle value is inner blower preset time T 2, i.e., the real-time humidity of electric heating tube is detected after each run T2
Value, until the real-time wet angle value < H, the condensed water on electric heating tube surface all evaporates under interior fan action at this time, described
Air conditioner delay state terminates, and the auxiliary heat pattern of electricity of the air conditioner is opened.
It should be noted that generally there is no compressor continuous operation time >=T1, and the case where humidity value < H.
More than, the present invention by control method be added two time conditions and a damp condition judgement, accurately
The starting of the auxiliary heat of control electricity is avoided long in air-conditioning so that all being evaporated condensed water using inner blower blowing before the auxiliary thermal starting of electricity
Start the auxiliary heat of electricity after the operation of time refrigeration/dehumidification and the case where violent abnormal sound occur, promotes the comfort that user uses；Another party
Face, condensed water all evaporate before the auxiliary thermal starting of electricity, will not cause adverse effect to electric heating tube, extend making for electric heating tube
Use the service life.
Second aspect of the present invention, provide a kind of air conditioner prevents abnormal sound control system, prevents abnormal sound control using above-mentioned
Method processed, the system comprises: module is obtained, for obtaining air conditioner compressor under refrigeration mode or dehumidification mode
The runing time of inner blower under continuous operation time and heating mode；Humidity sensor, for detecting at the electric heating tube
Humidity value；Judgment module, for judging whether the air conditioner meets entry condition；Control module, for meeting starting
After condition, the auxiliary heat pattern of the air conditioner starting electricity is controlled, entry condition here includes OnNow condition and meets air-conditioning
The condition that device delay state terminates.
Third aspect present invention provides a kind of air conditioner, including inner blower, compressor and electric heating tube, also comprising above-mentioned
Prevent abnormal sound control system, wherein the humidity sensor is set on the electric heating tube, the humidity sensor be one
It is a or multiple, it preferably 3, is evenly distributed on the electric heating tube, realization more accurately detects the wet of the electric heating tube
Angle value.
Although present disclosure is as above, present invention is not limited to this.Anyone skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
