Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to a control method and a control device of a fresh air conditioner and the air conditioner.
Background
An air conditioner is an essential household appliance in daily life. Air conditioners on the market currently have a wide variety of types and functions. The fresh air conditioner can meet the daily requirement of people on refrigeration or heating, and can also obtain outdoor fresh air by opening the fresh air function so as to guarantee the quality of indoor air.
However, the fresh air conditioners on the market have more complaints, which not only affect the use experience of users, but also are not favorable for public praise of air conditioner manufacturers. The complaints of the fresh air conditioner are mainly caused by the following reasons: when the user did not open the new trend function, the new trend air outlet was automatic air-out. The condition is that the existing fresh air conditioner is not additionally provided with a fresh air switch door, when outdoor environment is strong wind, outdoor wind is injected into the fresh air switch door from a fresh air pipeline and flows through a fresh air part, and the fresh air fan blade can be blown to rotate due to large wind pressure, so that the fresh air outlet is blown out. The fresh air function is not opened, but the fresh air outlet is air-out. Most users do not understand the principle, generally, the fresh air function is considered to be turned on by mistake and cannot be turned off, complaints are easy to cause, and the trust of the users on the brand of the air conditioner is reduced.
In order to solve the problem that the fresh air outlet discharges air when the fresh air function is not opened, the prior art mostly adopts a method of discharging air to the outside, but the specific wind speed of outdoor strong wind and the specific situation of fresh air motor rotation caused by the outdoor strong wind are not considered in the method. The problem that the fresh air outlet of the fresh air outlet cannot be exhausted out of the room for a long time or the fresh air motor is damaged can be caused.
Disclosure of Invention
In view of this, the present invention provides a control method, a control device and an air conditioner for a fresh air conditioner, so as to solve the problem of air outlet of a fresh air outlet when a fresh air function is not turned on, prevent outdoor air from directly blowing a user and reduce complaints of the user.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a control method of a fresh air conditioner is characterized in that when a fresh air function of the air conditioner is started, a fresh air motor rotates forwards to convey outdoor air indoors, and rotates backwards to convey indoor air outdoors, and when the fresh air function is not started and the fresh air motor rotates forwards to cause air to flow out of a fresh air outlet in the current state of the air conditioner, automatic fresh air motor control is achieved, and the following steps are specifically adopted: firstly, detecting a counter electromotive force E generated by the current fresh air motor due to forward rotation, and acquiring a forward rotation speed R1 output by the current fresh air motor according to the counter electromotive force E; then the fresh air motor is started and rotates reversely, and the reverse rotation speed R2 is R1+ A. The rotating speed of the fresh air motor in the positive rotation is determined by combining the rotating speed of the fresh air motor in the positive rotation under the external blowing action, so that the fresh air outlet stops air outlet. The problem that the rotating speed of the reverse rotation of the fresh air motor is directly adjusted to the maximum, the fresh air motor is stopped and rotated emergently, and the service life of the fresh air motor is influenced is avoided.
Further, the control method of the fresh air conditioner comprises the following steps:
s1, detecting whether a fresh air function is started, if so, normally operating the fresh air function by the air conditioner, and if not, executing a step S2;
s2, detecting whether the rotating speed of the current fresh air motor is 0, if so, jumping to the step S6, and if not, executing the step S3;
s3, detecting whether the fresh air motor is in reverse rotation, if so, jumping to the step S6, and if not, executing the step S4;
s4, starting a fresh air motor, reversing the fresh air motor, and controlling the fresh air motor automatically;
s5, after the first preset time T1, closing the fresh air motor, and returning to the step S2;
and S6, enabling the air conditioner to be in a normal standby state.
The control method of the fresh air conditioner can accurately judge whether the air outlet of the fresh air outlet is caused by opening the fresh air function or by backward flowing of fresh air, is simple and convenient, only needs to detect the rotation condition of the fresh air motor, and does not need to detect other conditions.
Further, A is 100-. When the reverse rotation speed R2 of the fresh air motor is determined, A is output on the basis of R1, so that the fresh air motor is ensured to stop rotating and the temperature rise of the fresh air motor is reliable, and the fresh air motor is protected.
Furthermore, when the fresh air motor is started and reversed, only the fresh air motor is started to enable the fresh air motor to be reversed, and the fresh air function is not started. The display panel of the air conditioner is free from the sign of the fresh air function, and the misunderstanding of a user is avoided.
Further, in step S5, the first preset time T1 is to ensure that after the time, the fresh air motor is turned on to rotate reversely to counteract the forward rotation of the fresh air motor, so that the fresh air motor does not rotate, and the fresh air outlet does not discharge air.
Furthermore, when the control method of the fresh air conditioner is adopted, if the fresh air function is detected to be opened at any time, the control of the fresh air conditioner is directly quitted, and the fresh air function is entered. When detecting the new trend function and opening, it is relatively poor to explain indoor air quality, needs the air between outdoor and the indoor to circulate and exchange, need not consider the no end air-out of new trend air outlet this moment.
Compared with the prior art, the control method of the fresh air conditioner has the following advantages:
(1) by adopting the control method of the fresh air conditioner, the reverse rotation speed of the fresh air motor is reasonably controlled when the fresh air motor is started to reversely rotate, so that the fresh air motor can be quickly stopped from rotating, and the fresh air outlet can not discharge air any more. The emergency stop rotation of the fresh air motor is avoided, and meanwhile, the temperature rise of the fresh air motor can be ensured to be reliable.

fig. 1 is a flowchart of a control method of a fresh air conditioner according to an embodiment of the present invention.
Detailed Description
The inventive concepts of the present disclosure will be described hereinafter using terms commonly employed by those skilled in the art to convey the substance of their work to others skilled in the art. These inventive concepts may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
The control method of the fresh air conditioner is used for the air conditioner, the air conditioner comprises an indoor unit, an outdoor unit and a fresh air component, and the fresh air component comprises a fresh air motor, fresh air blades, a fresh air inlet, a fresh air outlet, a fresh air duct and a fresh air pipeline. The fresh air inlet and the fresh air outlet are communicated through the fresh air duct. The fresh air outlet is communicated with the indoor space, and the fresh air inlet is communicated with the outdoor space through a fresh air pipeline. The fresh air motor is connected with the fresh air fan blade, and the fresh air motor is used for driving the fresh air fan blade to rotate forwards or backwards. Preferably, set up the new trend part in indoor set, the new trend part of being convenient for is direct to the indoor new trend of carrying.
In the invention, the fresh air motor is arranged to drive airflow to flow in from the fresh air inlet and flow out from the fresh air outlet in forward rotation, and to drive airflow to flow in from the fresh air outlet and flow out from the fresh air inlet in reverse rotation. When the fresh air function of the air conditioner is started, the air conditioner has a fresh air mode or an air exhaust mode by controlling the forward rotation or the reverse rotation of the fresh air motor. It should be noted that the forward rotation or the reverse rotation of the fresh air motor is a relative state, or the reverse rotation of the fresh air motor may be performed, and the airflow flows in from the fresh air inlet and flows out from the fresh air outlet, and the forward rotation of the fresh air motor causes the airflow to flow in from the fresh air outlet and flow out from the fresh air inlet.
When the air conditioner is in a fresh air mode, the fresh air motor rotates positively and drives the fresh air fan blades to rotate, so that outdoor air is sucked from the fresh air inlet, passes through the fresh air duct and is blown into a room through the fresh air outlet, and fresh outdoor air is conveyed into the room, so that the indoor air quality is improved, and the use experience of a user is improved. When the air conditioner is in the mode of airing exhaust, the fresh air motor rotates reversely and drives the fresh air fan blades to rotate so that indoor air is sucked from the fresh air outlet, passes through the fresh air duct and is exhausted outdoors through the fresh air inlet, and indoor dirty air is conveyed to the outdoor, so that the influence of the indoor air polluted by carbon dioxide, smoke and the like on the health of a user is avoided. Through opening the new trend function, when the user used the air conditioner in inclosed indoor space relatively, also can guarantee the quality of indoor environment, promote user's use and experience and feel.
The fresh air pipeline of the fresh air component is communicated with the outdoor environment, and the condition that the fresh air function is not started but the fresh air fan blade rotates can be caused under the interference of the outdoor environment due to the fact that the outdoor environment is changeable. For example, when the fresh air function is not started, outdoor wind can be poured into the fresh air duct to cause fresh air to flow backwards when the outdoor wind is in a strong wind day, and the fresh air fan blade can be blown to rotate due to the large wind pressure and the fresh air can be blown out from the fresh air outlet. Although the fresh air fan blade does not obtain the driving action provided by the fresh air motor, the fresh air fan blade can be blown by outdoor strong wind, and the fresh air outlet blows air. The user does not open at the new trend function, but when feeling the air-out of new trend air outlet, can regard as the new trend function mistake to open or the new trend part breaks down usually, leads to unnecessary complaint, has brought unnecessary trouble for user and air conditioner factory.
Therefore, the application provides a control method of a fresh air conditioner, which is used for accurately judging whether fresh air flows backwards or not and timely solving the problem of air outlet of a fresh air outlet when the fresh air flows backwards.
As shown in fig. 1, the control method of the fresh air conditioner includes the following steps:
s1, detecting whether a fresh air function is started, if so, normally operating the fresh air function by the air conditioner, and if not, executing a step S2;
specifically, whether detect the new trend function and open the accessible sensor and confirm whether the new trend function operates, perhaps whether accept the signal that the new trend function was opened. Under the general condition, the air conditioner automatically starts the fresh air function when detecting that the indoor air quality does not meet the preset condition, or starts the fresh air function when receiving an opening instruction sent by a user. When the fresh air function is opened, the fresh air motor naturally rotates, and the fresh air outlet also has air outlet. At the moment, the wind at the fresh air outlet is not caused by the backward flow of the fresh air, but is caused by the electric energy provided by the air conditioner for the fresh air motor. And the fresh air function is started as the active operation of the user, so that the user cannot think that the fresh air function is started by mistake.
S2, detecting whether the rotating speed of the current fresh air motor is 0, if so, jumping to the step S6, and if not, executing the step S3;
specifically, the misunderstanding of the user is only caused by the air outlet of the fresh air outlet when the fresh air function is not opened. Therefore, the rotating speed of the fresh air motor needs to be further judged when the fresh air function is not started. When the fresh air function is not started, if the rotating speed of the fresh air motor is 0, the fresh air cannot flow backwards. When the fresh air function is not started, if the rotating speed of the fresh air motor is not 0, the situation that the fresh air motor rotates due to the fact that fresh air flows backwards is probably shown.
S3, detecting whether the fresh air motor is in reverse rotation or not, if so, jumping to a step S6, and if not, executing a step S4;
specifically, detect the new trend motor reversal when the new trend function is not opened, explain that blow to the new trend motor reversal that outdoor arouses from indoor induced draft, the new trend air outlet does not air-out this moment also can not cause user's misunderstanding, consequently need not to handle, and the air conditioner keeps normal standby.
S4, starting a fresh air motor, reversing the fresh air motor, and controlling the fresh air motor automatically;
specifically, detect the new trend motor corotation when the new trend function is not opened, the new trend air outlet can the air-out this moment, very probably causes the new trend motor corotation because the new trend flows backward. If two conditions that the fresh air function is not started and the fresh air motor rotates forwards are met, the situation that the fresh air flows backwards is indicated.
The control method of the fresh air conditioner can accurately judge whether the air outlet of the fresh air outlet is caused by the opening of the fresh air function or the backflow of the fresh air, is simple and convenient, only needs to detect the rotation condition of the fresh air motor, and does not need to detect other conditions.
Because the fresh air outlet is but the air-out when the new trend function is not opened, cause user's complaint easily, consequently need take corresponding measure to make the new trend take place when the new trend flows backward the fresh air outlet does not go out the air. In the invention, the fresh air outlet is controlled by the automatic fresh air motor to ensure that no air is blown out.
More specifically, the following steps are adopted for entering the automatic fresh air motor control: firstly, detecting a counter electromotive force E generated by the current fresh air motor due to forward rotation, and acquiring a forward rotation speed R1 output by the current fresh air motor according to the counter electromotive force E; then the fresh air motor is started and rotates reversely, and the reverse rotation speed R2 is R1+ A. Turning on and reversing the fresh air motor means that the air conditioner provides electric energy for the fresh air motor to enable the fresh air motor to normally work and reverse, and the turning on and reversing of the fresh air motor is different from the turning of the fresh air motor under the blowing action of outdoor wind power. The back electromotive force E refers to the terminal voltage between two phases of the fresh air motor when the air conditioner is not started. The back electromotive force E of the fresh air motor can be detected through electric control. Since the detection method of the back electromotive force E and the obtaining of the rotation speed R1 of the fresh air motor by the back electromotive force E are both prior arts, they are not described herein again. Utilize counter electromotive force E to confirm the corotation rotational speed R1 of new trend motor output, can open the rotational speed R2 of new trend motor reversal by more accurate definite, quick messenger's new trend air outlet is no longer the air-out, reduces the air-out of new trend air outlet and blows directly to user.
When the fresh air function is not opened, the fresh air outlet automatically blows air because outdoor strong wind flows back to the fresh air pipeline, and the fresh air motor rotates forwards under the action of larger wind pressure. In order to prevent the fresh air outlet from discharging air, the fresh air motor is only required to stop rotating forwards. At the moment, the reverse rotation of the fresh air motor is started to offset the forward rotation of the fan under the action of outdoor air pressure, so that the fresh air motor stops rotating, and outdoor air is reduced from blowing a user through the fresh air outlet. When the fresh air motor is started to rotate reversely, only the fresh air motor is started to rotate reversely, and the fresh air function is not started, so that a mark without the fresh air function on a display panel of the air conditioner appears, and misunderstanding of a user is avoided.
When the fresh air motor is started to rotate reversely, the reverse rotation speed of the fresh air motor needs to be reasonably controlled, so that the fresh air motor stops rotating rapidly, and the fresh air outlet does not exhaust air. The outdoor environment condition changes according to the change of seasons, terrains and other factors, and the rotating speed of the fresh air motor in positive rotation is different when outdoor wind blows in different weather. If the rotation speed of the fresh air motor which is turned on for directly stopping rotation when fresh air flows backward is adjusted to the maximum, the fresh air motor can be stopped and rotated emergently, and the service life of the fresh air motor is influenced. Therefore, the rotating speed of the fresh air motor in the forward rotation mode needs to be specifically combined with the rotating speed of the fresh air motor in the forward rotation mode under the external blowing action to determine the rotating speed of the fresh air motor in the reverse rotation mode for stopping the rotation.
Specifically, the forward rotation speed R1 output by the current fresh air motor is obtained according to the counter electromotive force E when the fresh air motor rotates forward, but when the fresh air motor is started to rotate reversely, the reverse rotation speed of the fresh air motor is only set to be R1, so that the fresh air motor can only be ensured to stop rotating, and the heat dissipation problem of the fresh air motor is ignored. Therefore, a plurality of outputs A are needed on the basis of R1 to ensure that the fresh air motor stops rotating and the temperature rise of the fresh air motor is reliable. A is determined according to the model of the fresh air motor or selected by an air conditioner manufacturer according to experience values. More specifically, A is 100-.
S5, after the first preset time T1, closing the fresh air motor, and returning to the step S2;
specifically, after the fresh air motor is turned on to rotate reversely for the first preset time T1 in step S4, the fresh air motor is turned off to stop the reverse rotation of the fresh air motor. The first preset time T1 is to ensure that after the time, the fresh air motor is started to rotate reversely to counteract the forward rotation of the fresh air motor caused by the backward flow of the fresh air, so that the fresh air motor does not rotate any more, and the fresh air outlet does not exhaust air any more. The first preset time T1 may be determined according to an empirical value of an air conditioner manufacturer. The first preset time T1 may be 20-40 min. More specifically, the first preset time T1 is 30 min. In order to ensure that the fresh air outlet does not output air when the fresh air function is not opened in a new step, after the fresh air motor is closed within the first preset time TI, the step S2 is returned to detect whether the rotating speed of the current fresh air motor is 0 or not.
S6, the air conditioner is in normal standby state.
It should be noted that when the control method of the fresh air conditioner is adopted, if the fresh air function is detected to be opened at any time, the control of the fresh air conditioner is directly quitted, and the fresh air function is entered.
By adopting the control method of the fresh air conditioner, the problem of air outlet of the fresh air outlet when the fresh air function is not started can be timely and conveniently detected, and corresponding measures can be timely adopted. Open the new trend motor reversal through the initiative to the more accurate rotational speed R2 that adjusts the new trend motor reversal is equal to R1+ A according to the circumstances of the new trend motor corotation that concrete new trend flows backward and arouses, reach the purpose that makes new trend motor stall, the new trend air outlet does not go out the air, when avoiding the new trend air outlet air-out to arouse the user misunderstanding, can effectively protect the new trend motor, prevent new trend motor emergency braking or the unable radiating problem effectively of new trend motor.
The application also provides a control device of the fresh air conditioner, and the control method of the fresh air conditioner is used for controlling the air outlet of the fresh air conditioner caused by the backflow of fresh air. Fresh air conditioner controlling means includes: the rotating speed acquisition module is used for acquiring the rotating condition of the fresh air motor, such as the forward rotation or the reverse rotation of the fresh air motor; the time acquisition module is used for acquiring time information, such as first preset time T1 for starting the reverse rotation of the fresh air motor; the electric control acquisition module is used for acquiring the back electromotive force E of the fresh air motor; and the control module is used for regulating and controlling the control process of the fresh air conditioner according to the rotation condition of the fresh air motor, the back electromotive force E of the fresh air motor and other information.
