All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Aiming at the problem that the existing air conditioner cannot completely avoid blowing out cold air in a cold air prevention mode, the embodiment of the invention provides a cold air prevention control method and device for the air conditioner and the air conditioner, so that the problem is solved, the air conditioner can completely avoid blowing out cold air, and the user experience is improved.
To facilitate understanding of the present embodiment, a method for controlling cold air resistance of an air conditioner according to an embodiment of the present invention will be described in detail. Wherein, the air conditioner includes organism, air outlet and the wind-guiding door of locating the air outlet, and here the wind-guiding door includes: an outer air guide door and an inner air guide door; the outer air guide door can also be called a large air guide door, is arranged on the outer side of the cover plate of the machine body, and is matched with the air outlet in size and used for closing the air outlet; the inner air guide door can also be called a small air guide door. In addition, the air conditioner also comprises a controller arranged in the machine body, and an inner ring sensor and an indoor coil sensor which are in communication connection with the controller, wherein in practical application, the inner ring sensor is used for collecting the temperature of the inner ring and sending the temperature of the inner ring to the controller; the indoor coil pipe sensor is used for collecting the temperature of the indoor coil pipe and sending the collected temperature of the indoor coil pipe to the controller, so that the controller controls the air conditioner to operate according to the corresponding mode according to the temperature of the inner ring and the temperature of the indoor coil pipe. It should be noted that, the air conditioner is further provided with a PTC (Positive Temperature Coefficient) electric auxiliary heating element at the air outlet, and further includes other components such as a compressor, which may be specifically set according to actual conditions, and the embodiment of the present invention is not limited herein.
In addition, the air conditioner is also provided with a zero wind feeling mode, namely the zero wind feeling air conditioner, when a zero wind feeling instruction sent by a user through an air conditioner remote controller is received, the controller controls the air conditioner to operate according to the zero wind feeling mode, for example, in the zero wind feeling mode, the controller adjusts the angles of the outer air guide door and the inner air guide door to prevent the air conditioner from directly blowing.
Based on the air conditioner, an embodiment of the present invention provides a cold air prevention control method for an air conditioner, as shown in fig. 1, the method includes the following steps:
step S102, when the air conditioner is started according to a heating mode, acquiring the temperature of an inner ring;
specifically, when a user performs heating starting operation through an air conditioner remote controller, the controller controls the air conditioner to be started according to the heating mode according to the operation, and obtains the inner ring temperature collected by the inner ring sensor, so that whether the air conditioner enters a cold air prevention mode or not is controlled according to the inner ring temperature.
Step S104, judging whether the inner ring temperature is not greater than a preset inner ring temperature threshold value;
specifically, after receiving the inner ring temperature, the controller judges whether the inner ring temperature is not greater than a preset inner ring temperature threshold, and if so, namely the inner ring temperature is less than or equal to the preset inner ring temperature threshold, the controller indicates that the temperature is low at the moment and needs to perform a cold air prevention mode; otherwise, if the temperature of the inner ring is not larger than the preset temperature threshold value of the inner ring, the cold air prevention mode does not need to be entered at the moment, and the controller controls the air conditioner to directly operate according to the heating mode. Preferably, the preset inner-ring temperature threshold may be set to 20 ℃, or may be set according to actual situations, which is not limited to be described in the embodiment of the present invention.
Step S106, if yes, controlling the air conditioner to enter a cold air prevention mode; wherein the cold air prevention mode comprises a first stage and a second stage; in the first stage, the indoor fan is controlled to rotate reversely to blow out cold air in the air duct reversely, and meanwhile, the PTC is started to heat to obtain warm air; and in the second stage, controlling the indoor fan to rotate forwards, and blowing out warm air forwards according to the zero-wind-sense mode until the cold-wind-proof mode is exited.
Specifically, in the cold air prevention mode, the controller first controls the air conditioner to enter a first stage, in which the indoor fan is controlled to be reversed, or also called reversed, so as to reversely blow out cold air in the air duct at the moment, and the PTC is forcibly turned on to electrically heat air in the air conditioner; and after entering the second stage, the controller controls the indoor fan to rotate forwards to blow out the heated warm air forwards and blow out the warm air forwards according to the zero-wind-sense mode.
The air conditioner also comprises an outer air guide door and an inner air guide door, so that when warm air is blown out in the positive direction according to the zero wind sense mode, the controller also controls the outer air guide door to be opened, and simultaneously controls the inner air guide door to be closed, so that the direct direction of the discharged warm air to a user is avoided, meanwhile, the preheating time of the user can be given, namely, the air conditioner discharges non-cold air, and the temperature of the air conditioner does not rise directly to the user, so that the temperature sensed by the user is slowly increased, and the comfort of the user is improved. It should be noted that, after the PTC is forcibly turned on to be electrically heated in the first stage, the PTC is always in a working state, which improves the heating efficiency, thereby reducing the operating time of the second stage, reducing the waiting time of the user, and simultaneously alleviating the reliability problem caused by sudden pressure change of the system; and controlling the state of the PTC according to the actual condition until the cold air prevention mode is exited.
Further, after exiting the cold-blast protected mode, the method further comprises: the air conditioner is controlled to operate according to the heating mode, and because the air output by the air conditioner is warm air when the heating mode starts to work, on the basis of ensuring the comfort level of a user, the air conditioner continues to heat through the heating mode until the temperature set by the user is reached, so that the air conditioner can be operated from opening, the air conditioner can be prevented from blowing out cold air completely, and the user experience is improved.
Therefore, according to the air conditioner cold air prevention control method provided by the embodiment of the invention, the cold air in the air conditioner is blown out reversely through the first stage, then the air in the air conditioner is heated through the second stage, and the warm air is blown out forwardly according to the zero-wind-sensation mode, so that the direct blowing is avoided, the cold air blown out by the air conditioner is completely avoided, and the user experience is improved.
Further, since the cold wind prevention mode includes two stages, the method further includes: judging whether the air conditioner reaches a switching condition; wherein the switching condition comprises an operating time or an indoor coil temperature; if yes, the air conditioner is controlled to be switched from the first stage to the second stage. Specifically, after the air conditioner enters the cold air prevention mode, the air conditioner operates according to the first stage, and when the switching condition is met, the controller controls the air conditioner to be switched from the first stage to the second stage, so that the cold air prevention function of the air conditioner is realized through the first stage and the second stage.
In one possible handover method, the method includes: acquiring first time of reverse operation of an indoor fan; judging whether the first time reaches a preset first time threshold value; if yes, the air conditioner is controlled to be switched from the first stage to the second stage. Specifically, when the air conditioner operates according to a first stage, the controller controls the indoor fan to rotate reversely so as to discharge the cold air in the air duct, meanwhile, the controller also obtains a first time when the indoor fan rotates reversely, and when the first time reaches a preset first time threshold value, the air conditioner is controlled to enter a second stage from the first stage, so that the indoor fan is ensured to rotate reversely for a certain time by setting the first time threshold value so as to blow out the cold air in the air conditioner reversely, and the direct blowing to a user is avoided. The first time threshold may be 30s, or may be the remaining value, and may be specifically set according to an actual situation.
In another possible switching manner, the method includes: acquiring the temperature of a first indoor coil; judging whether the temperature of the first indoor coil reaches a preset first temperature threshold value or not; if so, acquiring the reached first duration; judging whether the first duration time reaches a preset second time threshold value or not; if yes, the air conditioner is controlled to be switched from the first stage to the second stage. Specifically, because in the first stage, the controller still forces to open PTC and opens and carry out electrical heating, consequently, can also judge the cold wind condition of blowing out through indoor coil pipe temperature, the first indoor coil pipe temperature that indoor coil pipe sensor gathered is acquireed to the controller promptly, and reach when first indoor coil pipe temperature predetermines first temperature threshold, and, when duration satisfied the second time threshold, control air conditioner gets into the second stage from the first stage, thereby ensure that PTC has carried out the heating of sufficient time to the air in the air conditioner, avoided withdrawing from air conditioner output cold wind behind the cold wind prevention mode. Preferably, the first temperature threshold may be set according to a comfortable temperature of a human body, such as 37 ℃ or 38 ℃, and may be set according to actual conditions.
Further, prior to the step of exiting the cold-blast protected mode, the method further comprises: acquiring the temperature of a second indoor coil; judging whether the temperature of the second indoor coil reaches a preset second temperature threshold value or not; if so, acquiring the reached second duration; judging whether the second duration time reaches a preset third time threshold value; if yes, the air conditioner is controlled to exit the cold air prevention mode. Specifically, in the second stage, acquire the indoor coil pipe temperature of second that indoor coil pipe sensor gathered, and reach predetermined second temperature threshold when the indoor coil pipe temperature of second, and, when the duration that reaches predetermined third time threshold, control air conditioner withdraws from and prevents cold wind mode, thereby when guaranteeing to withdraw from and prevent cold wind mode, the air heating in the air conditioner reaches sufficient temperature, ensure that the air at this moment is non-cold wind completely promptly, so that when operating according to the heating mode, exhaust air is non-cold wind completely, the condition that has partial cold wind in the exhaust air has been avoided, and then user's experience degree has been guaranteed.
This is illustrated here for ease of understanding. Another method for controlling the cold air prevention of an air conditioner, as shown in fig. 2, comprises the steps of:
step S202, the air conditioner is started to operate according to a heating mode;
step S204, judging whether to enter a cold air prevention mode; specifically, the temperature of the inner ring is obtained, and whether the temperature of the inner ring is not greater than a preset inner ring temperature threshold value is judged; if yes, executing step S206, otherwise, executing step S214; wherein the cold air prevention mode comprises a first stage and a second stage;
step S206, entering the first stage, controlling the indoor fan to reverse, and simultaneously starting PTC heating; in addition, in the first stage, it is also determined whether a handover condition is reached, here, the first time threshold is 30s, the first temperature threshold is 37 ℃, and the second time threshold is 15s as an example;
step S208, controlling the air conditioner to enter a second stage when the reverse running time of the indoor fan reaches 30S or the temperature of the first indoor coil reaches 37 ℃ and lasts for 15S;
specifically, in the first stage, the reverse running time of the indoor fan can be acquired, whether the reverse running time of the indoor fan reaches 30s or not is judged, and if yes, the air conditioner is controlled to enter the second stage; or obtaining the temperature of the first indoor coil, and controlling the air conditioner to enter the second stage when the temperature of the first indoor coil reaches 37 ℃ and the duration time reaches 15s or not;
step S210, in the second stage, controlling the indoor fan to rotate forwards, and blowing out warm wind forwards according to a zero wind sensation mode; meanwhile, the temperature of the second indoor coil is obtained to judge whether the cold air prevention mode exits, wherein the second temperature threshold is 40, and the third time threshold is 15s as an example;
step S212, when the temperature of the second indoor coil reaches 40 ℃ and the duration time reaches 15S, controlling the air conditioner to exit the cold-proof mode;
and step S214, operating according to a heating mode.
Therefore, the air conditioner cold air prevention control method provided by the embodiment of the invention is used for starting the zero-wind-feeling air conditioner according to the heating mode and then entering the cold air prevention mode; and, the cold air prevention mode includes two stages: in the first stage, an indoor fan is controlled to reversely rotate, cold air in an air duct is reversely blown out, and PTC heating is started to obtain warm air; in the second stage, the indoor fan is controlled to rotate forwards, warm air is blown out forwards in the zero-wind-sense mode, direct blowing is avoided, preheating time is given to a user until the user exits from the cold-wind-prevention mode, cold air blown out by the air conditioner is completely avoided, and user experience is improved.
