Technical Field

[0001] The present invention relates to the technical field of air treatment, and in particular to a method for purifying air using an air treatment system. Background Art

[0002] Existing air treatment devices only have ventilation functions, but do not have the function of disinfecting and sterilizing the air in the use space. If there are often gaseous pollutants such as oil smoke, formaldehyde or carbon monoxide in the use space, the gaseous pollutants will adhere to the walls for a long time and remain there or cause bacteria to grow. Summary of the invention

[0014] S25: After the ozone concentration in the use space is reduced to the health standard, the door control module and the window control module are started to open the doors and windows of the use space.

[0015] According to one embodiment of the present invention, in step S25, the method for reducing the ozone concentration in the use space to the health standard is: waiting time T2 to allow the ozone to decay naturally; or exhausting the ozone in the use space through ventilation; or opening the windows of the use space to exhaust the ozone to the outside through the windows.

[0016] According to one embodiment of the present invention, the ventilation device has a main control module, an air quality detection module and a fan module, and the air quality detection module and the fan module are connected to the main control module signal; when the air in the use space is purified by the ventilation method, the fan module runs, sucks the air in the use space and allows the outside air to enter the use space through the door or window of the use space to replenish air, the air quality detection module detects the air quality of the use space, and the main control module adjusts the operating power of the fan module according to the air quality conditions.

[0017] According to one embodiment of the present invention, the ozone disinfection module, the human body detection module, the door control module and the window control module are connected to the main control module signal. When the fan module is not started and the air quality detection module detects that the air quality in the use space is not up to standard, the main control module starts the human body detection module, and when the human body detection module does not detect a user in the use space, the air treatment system will use a disinfection method to disinfect the use space to purify the air in the use space.

[0018] According to an embodiment of the present invention, the human body detection module is a human body sensor. In step S21, the human body sensor detects whether there is a user in the use space and sends the information to the main control module.

[0019] According to one embodiment of the present invention, the human detection module is a camera, and the camera's field of view is the entire usage space. In step S21, the camera takes a photo of the usage space and transmits it to the main control module.

The human detection module transmits photos to the main control module and the APP module at the same time. The main control module controls the air treatment system to purify the air in the use space by ventilation or disinfection according to the user's instructions.

[0021] According to one embodiment of the present invention, during the process of the air treatment system using a disinfection method to purify the air, if a user needs to enter the use space, the ozone disinfection module stops running, the window control module controls the windows of the use space to open, and the ventilation device starts and ventilates the use space to accelerate the discharge of ozone in the use space.

[0022] According to one embodiment of the present invention, the ozone disinfection module includes an ozone generator and a blowing device. In step S23, when the ozone generator is started, the blowing device is started at the same time, and the blowing device blows the ozone generated by the ozone generator to promote the diffusion of ozone in the use space.

[0023] According to one embodiment of the present invention, when the ventilation device is applied to the kitchen space and installed above the stove, the ozone disinfection module is installed in the electrical control cavity of the ventilation device, the electrical control cavity of the ventilation device has an exhaust port arranged along the width direction, the air outlet side of the blowing device faces the exhaust port, the blowing device can operate alone, when the stove is running and the user is cooking in the kitchen space, the air treatment system uses ventilation method to purify the kitchen air, the fan module starts and draws out the fumes generated by cooking, the blowing device starts and exhausts air downward, forming an air curtain between the user and the stove.

[0024] Compared with the prior art, the method for purifying air by the air treatment system of the present invention has the following advantages:

[0025] The method for purifying air by the air treatment system of the present invention can switch between the ventilation method and the disinfection method to purify the use space. When the ventilation method is used, the air in the use space can be updated; when the disinfection method is used, if the human body detection module detects that there is no user in the use space, the doors and windows of the use space can be closed through the door control module and / or the window control module, and then the ozone disinfection module is controlled to release ozone to the use space. Ozone can disinfect and sterilize the air environment and walls of the use space, purify the air, and improve the air quality of the use space. Since it has been confirmed that there is no one in the use space and the doors and windows are closed when the ozone is released, it can prevent ozone from affecting the user, and the sterilization effect on the use space can be improved by closing the doors and windows.

However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0036] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0039] See also Figures 1 to 5The present invention discloses an air treatment system, which includes a ventilation device 1, an ozone disinfection module 2, a human body detection module 3, a door control module 4 and / or a window control module 5; the ventilation device 1 is used to ventilate the use space, and the ozone disinfection module 2 is used to release ozone to the use space; the human body detection module 3 is used to detect human activities, the door control module 4 is used to control the opening and closing of the door of the use space, and the window control module 5 is used to control the opening and closing of the door of the use space.

[0040] In this embodiment, the use space can be a kitchen, or a toilet or a storage room, etc. The use space has a door for users to enter and exit the use space. The use space can also have windows for users to open windows for ventilation. The ventilation device 1 is used to drive the flow of gas. For example, the gas in the use space can be discharged outside the use space so that fresh air can enter the use space to achieve ventilation of the use space. The ventilation device 1 can be a separate fan, or it can be a range hood or air purifier with a fan module 13.

[0041] The human detection module 3 is used to detect whether there is human activity in the use space to confirm whether there is anyone in the use space. The ozone disinfection module 2 is used to release ozone, which can sterilize and disinfect the air environment and walls of the use space, purify the air, improve the air quality of the use space, and reduce the growth of bacteria in the use space. Ozone has a wide spectrum of sterilization and can kill bacteria, viruses and a variety of microorganisms. It also has a strong function of removing mold, fishy smell, odor and other odors. After ozone disinfection is completed, the excess oxygen atoms combine into oxygen after 30 minutes, which does not cause pollution and has low consumption of consumables.

[0042] The door control module 4 is used to drive the door of the use space to open or close, and the window control module 5 is used to control the window of the use space to open or close. The air handling system can control the opening or closing of the door and window of the use space through the door control module 4 and the window control module 5. Specifically, taking the door control module 4 as an example, the door control module 4 includes a first slide rail, a first pulley, a first drive motor, a first transmission gear and a first transmission rack. The first slide rail is installed on the ground of the use space, the first pulley is installed at the bottom of the door, and the first pulley and the first slide rail are rollingly matched. The first drive motor is electrically connected to the main control module 11, and the drive shaft of the first drive motor is connected to the first transmission gear to drive the first transmission gear to rotate. The first transmission gear is meshed with the first transmission rack to convert the rotation of the first transmission gear into the linear motion of the first transmission rack. The first transmission rack is connected to the door to drive the door to move. Therefore, the main control module 11 can drive the door of the use space to reciprocate along the first slide rail by controlling the driving shaft of the first driving motor to rotate in the forward direction or the reverse direction, thereby controlling the door of the use space to open or close.

[0043] Correspondingly, the window control module 5 includes a second slide rail, a second pulley, a second drive motor, a second transmission gear and a second transmission rack. The second slide rail is installed on the windowsill of the use space, the second pulley is installed on the bottom of the window, and the second pulley and the second slide rail are in rolling cooperation. The second drive motor is electrically connected to the main control module 11, the drive shaft of the second drive motor is connected to the second transmission gear to drive the second transmission gear to rotate, the second transmission gear is meshed with the second transmission rack to convert the rotation of the second transmission gear into the linear motion of the second transmission rack, and the second transmission rack is connected to the window to drive the window to move. Therefore, the main control module 11 can drive the window of the use space to reciprocate along the second slide rail by controlling the drive shaft of the second drive motor to rotate in the forward direction or the reverse direction, thereby controlling the window of the use space to be opened or closed.

[0044] See also Figure 6 and Figure 7 The present invention also discloses a method for purifying air by an air treatment system, the method for purifying air by an air treatment system includes a ventilation method and a disinfection method; when the ventilation method is used to purify the air in the use space, the purification method includes the following steps:

[0045] S11: Confirm that the door or window of the occupied space is open;

[0046] S12: The ventilation device 1 is started and ventilates the use space;

[0047] S13: After the purification is completed, the ventilation device 1 is closed;

[0048] When disinfection is used to purify the air in an occupied space, the purification method includes the following steps:

[0049] S21: The human body detection module 3 confirms that there is no user in the usage space;

[0050] S22: Confirm that the doors and windows of the occupied space are closed;

[0051] S23: Ozone disinfection module 2 starts and releases ozone into the use space;

[0052] S24: The ozone disinfection module 2 is closed after the running time T1;

[0053] S25: After the ozone concentration in the use space is reduced to the health standard, the door control module 4 and the window control module 5 are started to open the doors and windows of the use space.

[0054] The ventilation method and the disinfection method can be switched. The user can choose to switch by himself, or the air handling system can automatically switch according to the current environment of the use space.

[0055] When using the ventilation method to purify the air in the use space, the air treatment system first confirms that the door or window of the use space is in an open state. The specific confirmation method can be to detect the rotation position of the drive shaft of the drive motor. After confirming that the doors and windows of the use space are in an open state, the ventilation device 1 is started to drive the airflow in the use space to flow outdoors, so that fresh air from the outdoors can enter the use space through the door or window, thereby achieving air renewal in the use space. After the ventilation device 1 is started for a preset time, it can be considered that the purification is completed, and the ventilation device 1 is controlled to be closed. It can be understood that in the process of ventilating the use space, since fresh air is harmless to the human body, there is no need to first confirm whether there is a human body in the use space.

[0056] When using disinfection to purify the air in the use space, the human body detection module 3 needs to first detect whether there is user activity in the use space. If there is user activity, the purification is suspended to prevent the ozone released by the ozone disinfection module 2 from affecting the user's body. If there is no user activity, first confirm whether the door or window of the use space is in a closed state. The specific confirmation method can be to detect the rotation position of the drive shaft of the drive motor. If the doors and windows of the use space are in an open state, the purification is suspended to avoid ozone flowing directly to the outdoors after release, affecting the purification effect. If it is confirmed that the doors and windows of the use space are in a closed state, the ozone disinfection module 2 starts and releases ozone to the use space. After the ozone disinfection module 2 runs for T1, it can be considered that there is enough ozone in the use space, and T1 can be calculated according to the release rate of the ozone and the amount of ozone required to diffuse the entire use space. After the ozone disinfection module 2 is turned off, the ozone concentration in the use space will gradually decrease. When the ozone concentration in the use space is reduced to the health standard, it means that the ozone concentration in the use space is no longer harmful to the human body, and the ozone has also fully disinfected the bacteria in the use space. At this time, the door control module 4 and the window control module 5 can be controlled to start, and the doors and windows of the use space can be opened, so that users can move normally in the use space.

[0057] In the method for purifying air with an air treatment system of the present invention, in step S25, the method for reducing the ozone concentration in the use space to the health standard is: waiting time T2 to allow the ozone to decay naturally; or exhausting the ozone in the use space through ventilation; or opening the windows of the use space to exhaust the ozone to the outside through the windows.

[0058] T2 can be obtained based on the decay rate of ozone and the amount of decay required to reach the health standard. The time required for the natural decay of ozone is longer, and at the same time, ozone can fully disinfect the bacteria in the use space. Another way is that after the disinfection method is completed, the method of purifying air in the air treatment system is switched to the ventilation method, that is, the ventilation device 1 is started to absorb and discharge the ozone and air in the use space to the outside. This method can reduce the ozone concentration in the use space to the health standard more quickly, and in the process of discharging ozone through the ventilation device 1, when ozone flows through the ventilation device 1 and the external exhaust pipe connected to the ventilation device 1, the ozone can disinfect the ventilation device 1 and the external exhaust pipe. Another way is to open the window of the use space and discharge ozone to the outside through the window. It can be understood that the window of the use space is generally directly connected to the outdoor air, and the door of the use space may lead to other rooms indoors. Therefore, the door of the use space cannot be opened in this way to avoid ozone from spreading to other spaces indoors, and to avoid people from accidentally breaking into the use space when the ozone concentration is not reduced to the health standard.

[0059] The method for purifying air by an air treatment system of the present invention, the ventilation device 1 has a main control module 11, an air quality detection module 12 and a fan module 13, the air quality detection module 12 and the fan module 13 are connected to the main control module 11 by signal; when the air in the use space is purified by the ventilation method, the fan module 13 runs, sucks the air in the use space and allows the outside air to enter the use space through the door or window of the use space to replenish air, the air quality detection module 12 detects the air quality of the use space, and the main control module 11 adjusts the operating power of the fan module 13 according to the air quality conditions.

[0060] The main control module 11 can receive the detection result signal from the air quality detection module 12, and send a control signal to the fan module 13. When the air in the use space is purified by the ventilation method, the fan module 13 absorbs and discharges the original air in the use space to the outside, and the fresh air outside naturally enters the use space through the doors and windows as a supplement of new air. In this process, the air quality detection module 12 detects the air quality of the use space and sends the detection result to the main control module 11. If the air quality of the use space is still not up to standard after the fan module 13 runs for a preset period of time, the main control module 11 will increase the operating power of the fan module 13 to increase the ventilation rate of the use space and shorten the ventilation time. The air quality detection module 12 can be a PM2.5 detection module or a detection module for other pollutants.

[0061] According to the method for purifying air by the air treatment system of the present invention, the ozone disinfection module 2, the human body detection module 3, the door control module 4 and the window control module 5 are signal-connected with the ventilation device 1 by the main control module 11. When the fan module 13 is not started and the air quality detection module 12 detects that the air quality of the use space is not up to standard, the main control module 11 starts the human body detection module 3, and when the human body detection module 3 does not detect a user in the use space, the air treatment system will use a disinfection method to disinfect the use space to purify the air in the use space.

[0062] The main control module 11 can receive the detection result signal from the human body detection module 3, and send control signals to the ozone disinfection module 2, the door control module 4 and the window control module 5. The air quality detection module 12 will first detect the air quality of the use space. If the air quality meets the standard, no disinfection is required; if the air quality does not meet the standard, it is necessary to start the ozone disinfection module 2 to release ozone for disinfection. Of course, before starting the ozone disinfection module 2, the human body detection module 3 needs to first detect whether there is user activity in the use space. If there is user activity, the ozone disinfection module 2 will not be started to prevent ozone from affecting the user's body; if there is no user activity, the ozone disinfection module 2 will be started.

[0063] The air quality and the presence or absence of human activities in the use space are triggering conditions for the disinfection mode. When the air quality detection module 12 detects that the air in the use space is not up to standard and the human detection module 3 detects that there is no user in the use space, the air treatment system switches to the disinfection method, the main control module 11 starts the ozone disinfection module 2, the door control module 4 or / and the window control module 5, the door control module 4 closes the door of the use space or / and the window control module 5 closes the window of the use space, and the ozone disinfection module 2 releases ozone to the use space. Ozone can disinfect and sterilize the air environment and walls of the use space to improve the air quality of the use space. Since it has been confirmed that there is no one in the use space and the doors and windows are closed when the ozone is released, it can prevent ozone from affecting the user and improve the sterilization effect of the use space by closing the doors and windows.

[0064] In the method for purifying air by an air treatment system of the present invention, the human body detection module 3 is a human body sensor. In step S21, the human body sensor detects whether there is a user in the use space and sends the information to the main control module 11. The human body sensor can directly detect whether there is a user in the use space. Compared with detecting human activities by laser or other methods, the detection result of the human body sensor is more real and reliable, thereby further preventing the air treatment system from mistakenly entering the disinfection mode when there is human activity in the use space, so as to improve the safety performance of the air treatment system.

[0065] In the method for purifying air by the air treatment system of the present invention, the human body detection module 3 is a camera, and the field of view of the camera is the entire use space. In step S21, the camera takes a photo of the use space and transmits it to the main control module 11, and the main control module 11 determines whether there is a user in the use space based on the photo. The main control module 11 pre-stores comparison data for determining whether there is a human body in the photo. After the camera takes a photo of the use space and transmits it to the main control module 11, the main control module 11 will parse the image data of the photo and compare it with the pre-stored comparison data. If the data matches, it means that there is a user in the use space. Detecting whether there is a human body in the use space by shooting can make the detection process more intuitive and effective, and further improve the reliability of the detection results.

[0066] The method for purifying air by an air treatment system of the present invention also includes an APP module, which is connected to the main control module 11 and the human detection module 3. The human detection module 3 transmits photos to the main control module 11 and the APP module at the same time. The main control module 11 controls the air treatment system according to the user's instructions to purify the air in the use space by using a ventilation method or a disinfection method.

[0067] The APP module can be installed on the user's smart terminal, such as the user's mobile phone or smart watch. In this way, the smart terminal can realize communication connection with the main control module 11 through the APP module, so that the user can interact with the air treatment system through the smart terminal. After the human body detection module 3 takes a photo of the use space, it can be transmitted to the user's smart terminal through the APP module. The user can judge whether there is a human body in the use space. After confirming that there is no human body in the use space, the user can control the door control module 4 and the window control module 5 to close the doors and windows of the use space through the smart terminal, and control the ozone disinfection module 2 to release oxygen. The APP module supports users to choose the ventilation method or disinfection method to disinfect the use space, which can further improve the safety performance of the air treatment system.

[0068] According to the method for purifying air by an air treatment system of the present invention, when the air treatment system adopts a disinfection method to purify air, if a user needs to enter a use space, the ozone disinfection module 2 stops running, and after the window control module 5 controls the windows of the use space to open, the ventilation device 1 starts and ventilates the use space, thereby accelerating the discharge of ozone in the use space.

[0069] In the process of air treatment system using disinfection method to purify air, the air treatment system can detect in real time whether the door is opened to confirm the user's intention to enter the use space. If the door is detected to be opened, it means that the user needs to enter the use space. At this time, the ozone disinfection module 2 stops releasing ozone, the window control module 5 controls the windows of the use space to open, and the ventilation device 1 starts to accelerate the ozone flow to the outside to prevent ozone from causing harm to the user who is about to enter the use space. In another embodiment, when the user needs to enter the use space, the intention instruction of entering the use space can also be sent to the air treatment system through the intelligent terminal. After receiving the instruction, the air treatment system can also shut down the ozone disinfection module 2 in time, and make the window control module 5 control the windows of the use space to open, and control the ventilation device 1 to start. In this way, in the process of air purification by disinfection method, even if the user needs to enter the use space, the ozone concentration in the use space can be reduced in time.

[0070] In the method for purifying air by the air treatment system of the present invention, the ozone disinfection module 2 includes an ozone generator 21 and a blowing device 22. In step S23, when the ozone generator 21 is started, the blowing device 22 is started at the same time, and the blowing device 22 blows the ozone generated by the ozone generator 21 to promote the diffusion of ozone in the use space. The ozone generator 21 can generate ozone by high-voltage discharge, ultraviolet irradiation or electrolysis, and the blowing device 22 is used to generate airflow to bring ozone into the use space and diffuse it in the use space. In this way, ozone can be diffused in the entire use space faster and more fully, thereby improving the disinfection effect of the use space.

[0071] The method for purifying air by an air treatment system of the present invention is that when the ventilation device 1 is applied to a kitchen space and installed above a stove, the ozone disinfection module 2 is installed in the electric control chamber of the ventilation device 1, and the electric control chamber of the ventilation device 1 has an exhaust port arranged along the width direction, and the air outlet side of the blowing device 22 faces the exhaust port. The blowing device 22 can operate alone. When the stove is running and the user is cooking in the kitchen space, the air treatment system uses a ventilation method to purify the kitchen air, the fan module 13 is started and the fumes generated by cooking are sucked out, and the blowing device 22 is started and exhausts air downward to form an air curtain between the user and the stove.

[0072] The ventilation device 1 is a range hood, which has a smoke collecting chamber and an air suction port connected to the smoke collecting chamber. The fan module 13 is arranged in the smoke collecting chamber. The range hood also has an electric control chamber, which is located at the front side of the head of the range hood. The ozone disinfection module 2 is arranged in the electric control chamber of the range hood. An exhaust port is arranged on the bottom plate of the electric control chamber. When the ozone disinfection module 2 is started, the ozone gas flows out through the exhaust port. When the range hood is running, the fan module 13 is started to generate negative pressure at the air suction port, so that the oil smoke near the air suction port can be sucked into the smoke collecting chamber and discharged outside the use space after purification. Installing the ozone disinfection module 2 in the electric control chamber of the range hood can not only improve the installation convenience of the ozone disinfection module 2 on the range hood, but also facilitate the subsequent maintenance and replacement of the ozone module. When the user starts the cooker to cook, the range hood enters the oil fume suction mode. In the oil fume suction mode, the fan module 13 starts to absorb and exhaust the oil fume generated during the cooking process, and at the same time, the blowing device 22 starts to blow air downward through the exhaust port to produce a wind curtain. The wind curtain can separate the oil fume from the user and prevent the oil fume from directly hitting the user from the front, so as to improve the user's cooking experience. It can be understood that in the oil fume suction mode, the ozone generator 21 remains closed to prevent the generation of ozone from affecting the user. In this way, the ozone disinfection module 2 can play different functions in different working modes of the range hood, thereby improving the overall operation effect of the air treatment system.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
