Based on the hardware structure, the embodiment of the fresh air system control method is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the fresh air system control method of the present invention, and the first embodiment of the fresh air system control method of the present invention is provided.
In a first embodiment, the fresh air system control method includes the following steps:
step S10: and when a fresh air closing instruction is received, closing the fresh air function according to the fresh air closing instruction.
It should be understood that the execution main body of this embodiment is the fresh air system control device, the fresh air system control device has functions of data communication, program operation, device driving, and the like, the fresh air system control device may be a computer device such as a computer or a control device such as an electronic control box, and of course, other devices having similar functions may also be used, and this embodiment is not limited thereto.
It can be understood that the fresh air system is mainly used for conveying air from the outdoor to the indoor, and simultaneously filters the conveyed air, thereby being beneficial to improving the indoor air quality. Referring to fig. 3, fig. 3 is a schematic diagram of an air exchange channel of a fresh air system. The air exchange channel of the fresh air system comprises a fresh air pipe and a fresh air structure air channel, and a filter screen is arranged between the fresh air pipe and the fresh air structure air channel and used for filtering air. The inside channel of the fresh air pipe can be directly communicated with the external space, air is sucked from the external space, the air is conveyed to the fresh air structure air channel, and the air is conveyed to the indoor space from the fresh air outlet after being treated by filtering and the like.
It should be noted that the fresh air system may be a fresh air blower or an air conditioner. When the new trend system is the air conditioner, when the installation, the air exchange passageway of new trend system can be connected through merging with the interior quick-witted inside and outside the air conditioner, a sharing installation pipe, and the inside accessible baffle of installation pipe keeps apart the air exchange passageway of new trend system and the interior quick-witted connection of interior quick-witted inside and outside the air conditioner. The present embodiment mode will be described by taking an air conditioner as an example.
It can be understood that the fresh air function means that the fresh air system is in an operating state, and air is sucked from the outside and fresh air is conveyed to the inside. The fresh air system also comprises input equipment such as a remote controller or a touch screen and the like, and the input equipment is used for realizing man-machine interaction. The remote controller or the touch screen is provided with keys, such as a power-on key, a power-off key and the like. The user can input the fresh air closing instruction by pressing the shutdown key so as to control the fresh air system to stop working. Of course, the interaction mode between the user and the fresh air system may also adopt a voice control mode, and the like, which is not limited in this embodiment.
It should be noted that the fresh air system further comprises a fan, when the fresh air function is started, the fan is in an electrified running state, and fresh air is conveyed from outside to inside through the fan. When the fresh air function is closed, the power supply of the fan is stopped so as to close the driving motor of the fan, and therefore the fresh air function is closed.
Step S20: and generating a first driving signal according to the fresh air closing instruction.
It should be noted that, in order to prevent the inner wall of the fresh air duct or the surface of the fresh air outlet and the fresh air inlet of the indoor unit from being condensed and frozen, a preset sealing assembly is arranged at the inlet of the fresh air duct in the embodiment. The sealing assembly comprises a sealing valve plate, and when the sealing valve plate is closed, the sealing valve plate can seal the fresh air pipe, so that two sides of the sealing valve plate are not communicated with each other. In addition, the gap between the sealing valve plate and the fresh air pipe is also provided with a sealing rib to improve the sealing performance. The sealing valve plate is also connected with a stepping motor through a rotating connecting rod, and after the motor is electrified, the rotating connecting rod is driven to rotate through the rotation of an output shaft of the motor, so that the sealing valve plate is pushed to open and close.
The first drive signal is a drive signal of the stepping motor. Specifically, the first driving signal may be a voltage signal, and the voltage signal is input to a power control module of the stepping motor, so as to control the power on and off of the stepping motor, and when the stepping motor is powered on, the motor rotates. Meanwhile, the voltage signal can also control the positive rotation and the negative rotation of the motor. For example, when the sealing assembly needs to be closed, the stepping motor is electrified and keeps rotating forwards; when the sealing assembly needs to be opened, the stepping motor is electrified and keeps reversing.
It can be understood that when the fresh air system control equipment receives a fresh air closing instruction, a voltage signal can be generated through the internal trigger, and the voltage signal is transmitted to the power supply control module of the stepping motor, so that the control of the sealing component is realized.
Step S40: and closing a preset sealing assembly at the inlet of the fresh air pipe according to the first driving signal so as to enable the inner channel of the fresh air pipe to be in an isolated state from the external space.
It can be understood that when the received instruction is a fresh air closing instruction, the first driving signal enables the motor of the preset sealing assembly to be electrified, the preset sealing assembly at the inlet of the fresh air pipe is closed, and therefore the inner channel of the fresh air pipe is isolated from the external space.
In the first embodiment, when a fresh air closing instruction is received, a fresh air function is closed according to the fresh air closing instruction; generating a first driving signal according to the fresh air closing instruction; and closing a preset sealing assembly at the inlet of the fresh air pipe according to the first driving signal so as to enable the inner channel of the fresh air pipe to be in an isolated state from the external space. According to the invention, the sealing assembly is arranged at the inlet of the fresh air duct, and when the fresh air system does not operate, the inlet of the fresh air duct is sealed, so that external air is prevented from permeating into the fresh air duct, and condensation and icing on the inner wall of the fresh air duct or the surface of a fresh air outlet and a common air inlet of an indoor unit are avoided. In addition, the dust can be prevented from being accumulated in the internal channel of the fresh air pipe, and insects such as mosquitoes and cockroaches are prevented from crawling.
Referring to fig. 4, fig. 4 is a schematic flow chart of a control method of a fresh air system according to a second embodiment of the present invention, and the control method of the fresh air system according to the second embodiment of the present invention is provided based on the first embodiment shown in fig. 2.
In the second embodiment, before the step S40, the method further includes:
step S301: when a fresh air closing instruction is received, a first preset timer is started.
It should be noted that, because the closing process of the fresh air function is not complete instantaneously, when the fresh air function is closed, air still circulates. Also, the closing process of the seal assembly cannot be accomplished instantaneously. Therefore, when the two processes run simultaneously, noise is generated, which affects the user experience.
In the present embodiment, the two processes are shifted from each other, and a delay is provided for the closing process of the seal assembly when the fresh air closing command is received. Specifically, when a fresh air closing instruction is received, a first preset timer is started to time, so that a time delay function is realized.
Step S302: and judging whether the timing time of the first preset timer reaches a first preset time.
It should be noted that the first preset time may be set to about 10 seconds. When the timing time of the timer does not reach 10 seconds, the fresh air function is not completely closed, and the operation is not performed at the moment. When the timing time of the timer does not reach 10 seconds, the fresh air function is completely closed, and the sealing assembly can be closed at the moment. Of course, the first preset time may also be set to other values according to the user requirement, which is not limited in this embodiment.
Step S303: and when the timing time of the first preset timer reaches the first preset time, closing a preset sealing assembly at the inlet of the fresh air pipe according to the first driving signal so as to enable the inner channel of the fresh air pipe to be in an isolated state from the external space.
It can be understood that after the fresh air function is completely closed, the sealing assembly closing process is executed, and the generation of noise can be avoided. In specific implementation, the stepping motor corresponding to the preset sealing assembly is electrified according to the first driving signal so as to drive the preset sealing assembly to close; recording first power-on time of the stepping motor, and judging whether the first power-on time reaches third preset time; and when the first electrifying time reaches the third preset time, stopping electrifying the stepping motor so as to enable the inner channel of the fresh air pipe and the external space to be in an isolated state.
It should be noted that, in order to ensure the safety of the sealing assembly, the speed of the sealing valve sheet cannot be too fast when the sealing assembly is controlled to open and close. Therefore, it is necessary to maintain the stepper motor energized for a certain amount of time to ensure that the seal assembly is fully closed. Usually the live time is about 5 seconds, sets up to predetermine the time and is 5 seconds promptly, when step motor circular telegram, records the live time, after the live time reaches 5 seconds, breaks off step motor's power, and seal assembly closes completely this moment, and fresh air pipe inner channel is in the isolated state with exterior space. Of course, the power-on time may be set to other values, which is not limited in this embodiment.
It should be noted that, in order to prevent the situation that the power-on time is set too long, after the sealing assembly is closed, the stepping motor is still running, which affects the service life of the stepping motor, and the torque of the stepping motor can be detected. Through setting up the moment of torsion threshold value, when the motor moment of torsion reaches the moment of torsion threshold value, disconnection step motor power prevents that step motor from burning out.
In the second embodiment, when a fresh air closing instruction is received, a first preset timer is started; judging whether the timing time of the first preset timer reaches a first preset time or not; and when the timing time of the first preset timer reaches the first preset time, closing a preset sealing assembly at the inlet of the fresh air pipe according to the first driving signal so as to enable the inner channel of the fresh air pipe to be in an isolated state from the external space. This implementation has avoided closing the new trend function simultaneously and has closed the noise that seal assembly produced through setting up the time delay closing between the new trend function and closing seal assembly, has improved user experience.
Referring to fig. 5, fig. 5 is a schematic flow chart of a control method of a fresh air system according to a third embodiment of the present invention, and the control method of the fresh air system according to the third embodiment of the present invention is provided based on the first embodiment and the second embodiment. The present embodiment is explained based on the first embodiment.
In the third embodiment, after the step S40, the method further includes:
step S50: and when a fresh air starting instruction is received, generating a second driving signal according to the fresh air starting instruction.
The second drive signal is a drive signal of the stepping motor. Specifically, the second driving signal may be a voltage signal, and the voltage signal is input to a power control module of the stepping motor, so as to control the power on and off of the stepping motor, and when the stepping motor is powered on, the motor rotates. Meanwhile, the voltage signal can also control the positive rotation and the negative rotation of the motor. For example, when the sealing assembly needs to be closed, the stepping motor is electrified and keeps rotating forwards; when the sealing assembly needs to be opened, the stepping motor is electrified and keeps reversing.
It can be understood that when the fresh air system control equipment receives a fresh air closing instruction, the fresh air system control equipment can generate two voltage signals through the internal trigger and transmit the voltage signals to the power supply control module of the stepping motor, so that the control of the sealing assembly is realized.
Step S60: and opening a preset sealing assembly at the inlet of the fresh air pipe according to the second driving signal so as to enable the internal channel of the fresh air pipe and the external space to be in a straight-through state.
It can be understood that when the received instruction is a fresh air opening instruction, the second driving signal enables the motor of the preset sealing assembly to be electrified, and the preset sealing assembly at the inlet of the fresh air pipe is opened, so that the inner channel of the fresh air pipe and the external space are in a direct connection state.
Step S70: and starting the fresh air function according to the fresh air starting instruction so as to suck fresh air through the fresh air pipe.
It can be understood that the fresh air system is mainly used for conveying air from the outdoor to the indoor, and simultaneously filters the conveyed air, thereby being beneficial to improving the indoor air quality. After the fresh air function is opened, the air is sucked from the external space, conveyed to the fresh air structure air channel and conveyed to the indoor space from the fresh air outlet after being treated by filtering and the like.
It should be noted that, since the opening process of the sealing assembly cannot be completed instantaneously, the opening process of the fresh air function is not complete instantaneously. Therefore, when the two processes run simultaneously, noise is generated, which affects the user experience. In the embodiment, the two processes are staggered, and when a fresh air starting instruction is received, a delay is set for the starting process of the fresh air function. Specifically, when a fresh air starting instruction is received, a second preset timer is started; judging whether the timing time of the second preset timer reaches a second preset time or not; and when the timing time of the second preset timer reaches the second preset time, executing the step of starting a fresh air function according to the fresh air starting instruction so as to suck fresh air through the fresh air pipe.
It should be noted that the second preset time may be set to about 10 seconds. When the timing time of the timer does not reach 10 seconds, the sealing assembly is not completely opened, and the action is not carried out at the moment. When the timing time of the timer does not reach 10 seconds, the sealing assembly is completely opened, and at the moment, new workers can be started. Of course, the second preset time may also be set to other values according to the user requirement, which is not limited in this embodiment.
It should be noted that, also in order to ensure the safety of the sealing assembly, the speed of the sealing valve plate cannot be too fast when controlling the opening and closing of the sealing assembly. When the sealing assembly is opened, the stepping motor corresponding to the preset sealing assembly is electrified according to the second driving signal so as to drive the preset sealing assembly to be opened; recording second power-on time of the stepping motor, and judging whether the second power-on time reaches fourth preset time; and when the second electrifying time reaches the fourth preset time, stopping electrifying the stepping motor so as to enable the inner channel of the fresh air duct and the external space to be in a direct connection state.
It should be noted that, the normal power-on time may be about 5 seconds, that is, the preset time is set to 5 seconds, when the stepping motor is powered on, the power-on time is recorded, and after the power-on time reaches 5 seconds, the power supply of the stepping motor is turned off, at this time, the sealing assembly is completely opened, and the inner channel of the fresh air duct and the external space are in a direct connection state. Of course, the power-on time may be set to other values, which is not limited in this embodiment.
It should be noted that, in order to prevent the situation that the setting of the power-on time is too long, after the sealing assembly is opened, the stepping motor still runs, which affects the service life of the stepping motor, the torque of the stepping motor can be detected. Through setting up the moment of torsion threshold value, when the motor moment of torsion reaches the moment of torsion threshold value, disconnection step motor power prevents that step motor from burning out.
It should be noted that, when the fresh air system is not in operation, the air flow in the fresh air channel is not smooth, and the air quality is not good. For avoiding the start-up of new trend function, directly carry the not good air of quality to indoor, this embodiment sets up the ladder when the new trend function starts and starts, mixes the air in the passageway.
In concrete implementation, a fresh air driving motor is started according to the fresh air starting instruction; and adjusting the rotating speed of the fresh air driving motor to a preset rotating speed according to a preset time interval and a preset speed ratio so as to start the fresh air function, and sucking fresh air through the fresh air pipe.
To more clearly illustrate the technical solution, the following description is made with reference to examples:
the time interval is set to be 30 seconds, the speed regulation ratio is 1.5, and the initial rotating speed of the fan is 100rad/min when the fresh air driving motor is started. Then, after the fresh air driving motor is started, the fan runs at 100rad/min, and after 30 seconds, the rotating speed of the fan is changed into 150 rad/min; after 30 seconds, the fan speed is changed to 225rad/min until the rated speed is reached. Of course, the time interval and the speed ratio may be other values, and the embodiment is not limited thereto.
In a third embodiment, when a fresh air starting instruction is received, a second driving signal is generated according to the fresh air starting instruction; opening a preset sealing assembly at the inlet of the fresh air pipe according to the second driving signal so as to enable the internal channel of the fresh air pipe and the external space to be in a straight-through state; and starting the fresh air function according to the fresh air starting instruction so as to suck fresh air through the fresh air pipe. When the new trend function was opened, this embodiment opened seal assembly earlier, set up the time delay between the two simultaneously, avoided producing the noise. In addition, when the fresh air driving motor is started, the air in the channel is mixed by setting the ladder to start, and the situation that the air with poor quality in the channel is directly conveyed indoors is avoided.
In addition, an embodiment of the present invention further provides a storage medium, where a fresh air system control program is stored on the storage medium, and the steps of the fresh air system control method are implemented when the fresh air system control program is executed by a processor.

In addition, referring to fig. 6, fig. 6 is a diagram illustrating a fresh air system control device according to an embodiment of the present invention.
In this embodiment, the fresh air system control device includes:
and the fresh air function control module 10 is used for closing the fresh air function according to the fresh air closing instruction when receiving the fresh air closing instruction.
It can be understood that the fresh air system is mainly used for conveying air from the outdoor to the indoor, and simultaneously filters the conveyed air, thereby being beneficial to improving the indoor air quality. Generally, the air exchange channel of the fresh air system comprises a fresh air pipe and a fresh air structure air duct. The inside channel of the fresh air pipe can be directly communicated with the external space, air is sucked from the external space, the air is conveyed to the fresh air structure air channel, and the air is conveyed to the indoor space from the fresh air outlet after being treated by filtering and the like.
It should be noted that the fresh air function means that the fresh air system is in an operating state, and air is sucked from the outside and fresh air is conveyed to the inside. The fresh air system also comprises input equipment such as a remote controller or a touch screen and the like, and the input equipment is used for realizing man-machine interaction. The remote controller or the touch screen is provided with keys, such as a power-on key, a power-off key and the like.

Of course, the interaction mode between the user and the fresh air system may also adopt a voice control mode, and the like, which is not limited in this embodiment.
It should be noted that the fresh air system further comprises a fan, when the fresh air function is started, the fan is in an electrified running state, and fresh air is conveyed from outside to inside through the fan. When the fresh air function is closed, the power supply of the fan is mainly stopped so that the driving motor of the fan is closed, and the fresh air function is closed.
And the signal generating module 20 is configured to generate a first driving signal according to the fresh air closing instruction.
It should be noted that, in order to prevent the inner wall of the fresh air duct or the surface of the fresh air outlet and the fresh air inlet of the indoor unit from being condensed and frozen, a preset sealing assembly is arranged at the inlet of the fresh air duct in the embodiment. The sealing assembly comprises a sealing valve plate, and when the sealing valve plate is closed, the sealing valve plate can seal the fresh air pipe, so that two sides of the sealing valve plate are not communicated with each other. In addition, the gap between the sealing valve plate and the fresh air pipe is also provided with a sealing rib to improve the sealing performance. The sealing assembly is further connected with a stepping motor through a rotating connecting rod, and after the motor is electrified, the rotating connecting rod is driven to rotate through the rotation of the output shaft of the motor, so that the sealing assembly is pushed to be opened and closed.
