[0001] The present invention relates to the field of air conditioning, and in particular to an air detection device, a duct machine, a method and a computer-readable storage medium. Background Art

[0002] The cleanliness of indoor air always affects the comfort and sense of security of residents. The musty smell and odor in the room directly affect the living experience of residents. Colorless and odorless harmful gases such as carbon monoxide and coal gas pose a huge threat to the life safety of residents, especially at night when residents are sleeping soundly and cannot detect the leakage of harmful gases in time, which threatens the life safety of residents.

[0003] Therefore, the prior art discloses a method of integrating an air purifier into a ducted air conditioner, so that the ducted air conditioner has both a temperature regulation function and an air purification function, thereby achieving functional diversification, while saving more space and cost. However, the ducted air conditioner with an air purification function in the prior art has a single operating mode and still requires a large operating power, which significantly increases the power consumption of the ducted air conditioner. In addition, when the ducted air conditioner is not performing air purification, a large amount of normal air will still pass through the purification device, reducing the service life of the purification device. Summary of the invention

[0004] In view of this, the present invention aims to propose an air detection device, a duct machine, a method and a computer-readable storage medium to solve the problems in the prior art that the duct machine with air purification function has a single operating mode, high energy consumption, and cannot determine whether effective purification has been performed.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] An air detection device includes an air duct and a detection unit, wherein a first flow channel and a second flow channel are arranged inside the air duct, a purification module is arranged in at least one of the flow channels, and a control door is arranged between the first flow channel and the second flow channel, wherein the control door controls the opening or closing of the first flow channel and the closing or opening of the second flow channel according to the detection result of the detection unit. By arranging a double air duct for air outlet, the purification function is increased without affecting normal use, and odors and some dangerous gases are filtered, and the safety performance is good. The switching between different flow channels is controlled by the control door, and the power consumption is small and easy to operate; and the purification module is arranged in the second flow channel, so that during normal air supply, the air does not contact the purification module, and the purification module does not cause obstruction to the air intake, thereby ensuring the air intake in the air duct, and at the same time is isolating the purification module from the outside air, preventing the normal air from consuming the purification module, and extending the service life of the purification module.

[0007] Furthermore, an air inlet is provided at one end of the air duct, and an air outlet is provided at the other end, and a fan and a heat exchanger are included between the air inlet and the air outlet, and the detection unit includes a first detection unit and a second detection unit, the first detection unit is provided at the air inlet, and the second detection unit is provided at the air outlet. The setting of the first detection unit enables the first detection unit to continuously detect whether the air entering the air duct contains abnormal gases 24 hours a day, regardless of whether the fan is running, to ensure the safety of the indoor environment, and the setting of the second detection unit enables the air quality to be detected only when the fan is running, which can effectively detect the purification effect of the purification module on the one hand, ensure the indoor air quality, and on the other hand, improve its service life.

[0008] Furthermore, the first flow channel is set as a straight flow channel, and the second flow channel is set at least on one side of the first flow channel. The first flow channel is set as a straight flow channel to ensure smooth air flow during normal air outlet; the second flow channel is set on one side of the first flow channel to ensure that the first flow channel and the second flow channel are effectively distinguished and do not affect each other.

[0009] Furthermore, an upper bottom plate is provided between the first flow channel and the second flow channel, a first notch and a second notch are provided between the two ends of the upper bottom plate and the lower bottom surface of the first flow channel, respectively, and the control door is provided at the two ends of the upper bottom plate for closing or opening the first notch and the second notch. It is ensured that the air entering the air duct through the air inlet enters the second flow channel through the first notch for purification and then is discharged through the second notch, so as to ensure smooth air flow in the second flow channel, prevent a large amount of air from accumulating in the second flow channel and being unable to be discharged, thereby affecting the air intake, and improve the operating stability of the air detection device and the air duct machine.

[0010] Furthermore, the second flow channel is arranged between the first notch and the second notch, the control door is arranged as a rotatable or movable partition, and the control door is used to close or open the second flow channel. The first notch forms an air inlet of the second flow channel, and the second notch forms an air outlet of the second flow channel, so as to facilitate the smooth circulation of air in the second flow channel, and the control door is arranged as a rotatable or movable partition, so as to facilitate the control of the selection and switching between the first flow channel and the second flow channel.

[0013] 1) By setting up a double air duct outlet, the purification function is increased without affecting normal use, filtering odors and some dangerous gases, and the safety performance is good. In addition, the normal air supply and air purification are completely separated, so that during normal air supply, the air does not contact the purification module, and the purification module does not hinder the air intake, ensuring the air intake in the air duct. At the same time, the purification module is isolated from the outside air to prevent normal air from consuming the purification module and extend the service life of the purification module. In addition, by rotating the lighter baffle to control the switching between different flow channels, the power consumption is small and easy to operate.

[0014] 2) The first detection unit is set up so that regardless of whether the fan is running or not, the first detection unit can continuously detect whether the air entering the air duct contains abnormal gases 24 hours a day to ensure the safety of the indoor environment. The second detection unit is set up so that the air quality is only detected when the fan is running. On the one hand, it can effectively detect the purification effect of the purification module to ensure the indoor air quality, and on the other hand, it can improve its service life.

[0015] The present invention also provides an air detection method, using the above-mentioned air detection device, the method comprising:

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figure 1~2 As shown, this embodiment provides an air detection device, including an air duct 1 and a detection unit, the detection unit is used to detect air components, the detection unit is arranged inside or at the end of the air duct 1, the front and rear ends of the air duct 1 are respectively provided with an air inlet 13 and an air outlet 14, and a fan 2, a heat exchanger 3 and a purification module 6 are arranged between the air inlet 13 and the air outlet 14 in the air duct 1;

[0036] A first flow channel 9 and a second flow channel 10 are arranged inside the air duct 1 . A purification module 6 is arranged in at least one of the flow channels. Preferably, the purification module 6 is arranged in the second flow channel 10 .

[0037] In normal air supply mode, air passes through the first flow channel 9 and is discharged from the air outlet 14. In air purification mode or alarm mode, air passes through the second flow channel 10 and is filtered and purified by the purification module 6 and is discharged from the air outlet 14. A control door is provided between the first flow channel 9 and the second flow channel 10. The control door controls the switching of the first flow channel 9 and the second flow channel 10 according to the detection result of the detection unit, that is, the control door controls the opening or closing of the first flow channel 9 and the closing or opening of the second flow channel 10 according to the detection result of the detection unit.

[0038] By setting up a double air duct outlet, the purification function is increased without affecting normal use, filtering odors and some dangerous gases, and the safety performance is better. In addition, the normal air supply and air purification are completely separated, so that during normal air supply, the air does not contact the purification module 6, and the purification module 6 does not hinder the air intake, ensuring the air intake in the air duct. At the same time, the purification module 6 is isolated from the outside air to prevent normal air from consuming the purification module and extend the service life of the purification module 6. In addition, by rotating the light-weight partition to control the switching between different flow channels, the power consumption is small and easy to operate.

[0039] As part of an embodiment of the present invention, the air detection device described in this embodiment also includes a control unit and an alarm unit 15. The detection unit, the control unit and the alarm unit are electrically connected to ensure effective signal transmission. The specific setting positions of the control unit and the alarm unit 15 are not limited.

[0040] The control unit switches between different operation modes according to different signals detected by the detection unit. When the detection unit detects that the air entering the air duct 1 contains abnormal components, the control unit controls the alarm unit 15 to automatically alarm, and the control unit controls the partition to rotate and switch to the second flow channel 10 to execute the air purification mode; when the detection unit detects that the air purified by the purification module 6 through the second flow channel 10 still contains abnormal gases, that is, the abnormal gases cannot be absorbed by the purification module 6, the control unit controls to enter the alarm mode, and the alarm unit continues to alarm; when the detection unit detects that the air entering the air duct 1 does not contain abnormal components, the control unit controls the partition to rotate and switch to the first flow channel 9 to execute the normal air supply mode.

[0041] Furthermore, the judgment standard of whether the air contains abnormal components in this embodiment is set according to the actual content of harmful substances that the human body can withstand, or can also be set independently according to the user's own habits and needs.

[0042] This embodiment sets the above three operating modes so that users can choose according to actual conditions. It has a wide range of applications and is convenient for the promotion and application of the above air detection device.

[0043] The air detection device also includes a selection terminal. When the user needs to actively remove odors or harmful substances in the indoor air, the user can also manually choose to turn on the air purification mode through the selection terminal. When the user has no air purification needs, the user can manually choose to turn on the normal air supply mode. It has a wide range of applications.

[0044] Furthermore, the first flow channel 9 is configured as a straight flow channel to ensure smooth air flow during normal air outlet; the second flow channel 10 is configured on at least one side of the first flow channel 9 .

[0045] Preferably, the second flow channel 10 is arranged at the lower part or side of the first flow channel 9, the top or one side of the second flow channel 10 is flush with the bottom or one side of the first flow channel 9, and the second flow channel 10 is arranged between the heat exchanger 3 and the air outlet 14, and the opening or sealing of the second flow channel 10 is controlled by the control door. In this way, the first flow channel 9 and the second flow channel 10 are distinguished, so that the normal air supply mode and the air purification mode do not affect each other.

[0046] Furthermore, the control door can be configured as a rotatable or movable partition, which has a simple structure and is easy to operate.

[0047] An upper bottom plate 16 is arranged between the first flow channel 9 and the second flow channel 10 , and the upper bottom plate 16 forms the top plate of the second flow channel 10 . A lower bottom plate 17 parallel to the upper bottom plate 16 is arranged below the upper bottom plate 16 , and the second flow channel 10 is formed between the upper bottom plate 16 and the lower bottom plate 17 .

[0048] A first notch 19 and a second notch 20 are respectively arranged between the two ends of the upper base plate 16 and the lower bottom surface 18 of the first flow channel 9. The second flow channel 10 is arranged between the first notch 19 and the second notch 20. The first notch 19 forms the air inlet end of the second flow channel 10, and the second notch 20 forms the air outlet end of the second flow channel 10, ensuring that the air entering the air duct 1 through the air inlet enters the second flow channel 10 through the first notch 19 for purification and then is discharged through the second notch 20, thereby ensuring smooth air flow in the second flow channel 10, preventing a large amount of air from accumulating in the second flow channel 10 and being unable to be discharged to affect the air intake, thereby improving the operating stability of the air detection device and the air duct machine.

[0049] Furthermore, control doors are provided at both ends of the upper bottom plate 16 for sealing or opening the first notch 19 and the second notch 20, that is, the control door is used to close or open the second flow channel 10. The control door includes a first baffle 4 and a second baffle 8, the first baffle 4 is connected to one end of the upper bottom plate 16 through a first driving device 5, and the second baffle 8 is connected to the other end of the upper bottom plate 16 through a second driving device 7. The first baffle 4 is used to open or close the first notch 19, and the second baffle 8 is used to open or close the second notch 20.

[0050] Preferably, the first driving device 5 and the second driving device 7 are both configured as shaft motors to facilitate the rotation of the first partition 4 and the second partition 8, and the shaft motor has a simple structure, which saves the internal space of the air duct 1 and avoids affecting the air flow.

[0051] Furthermore, the detection unit includes a first detection unit 11 and a second detection unit 12. The detection unit sends the detected signal to the control unit, and the control unit controls the rotation of the rotatable first partition 4 and the second partition 8 according to the detection signal, thereby realizing the switching of different operation modes.

[0052] The first detection unit 11 is arranged at the air inlet 13, or at the front end of the air inlet 13, or at a position close to the air inlet 13 before the fan 2, and is used to detect whether the air entering the air duct 1 contains abnormal gas. The second detection unit 12 is arranged at the air outlet 14 or at the front end of the air outlet 14, and is used to detect whether the air passing through the second flow channel 10 can be purified and absorbed by the purification module 6. Preferably, the second detection unit 12 is arranged after the second flow channel 10, and more preferably, the second detection unit 12 is arranged at the air outlet end or after the air outlet end of the second flow channel 10. The arrangement of the first detection unit 11 enables the first detection unit 11 to detect the air quality 24 hours a day regardless of whether the fan 2 is running, so as to ensure the safety of the indoor environment; the second detection unit 12 only detects the air quality when the fan 2 is running, which can effectively detect the purification effect of the purification module 6 on the one hand, ensure the indoor air quality, and on the other hand, improve its service life.

[0053] When the air detection device starts to operate, the fan 2 runs, and the air circulates in the air duct 1. At this time, the first detection unit 11 located at the air inlet 13 detects the air quality of the incoming air in real time, and the second detection unit 12 located near the air outlet 14 detects the air quality of the outgoing air in real time, and sends the detected signal to the control unit. When the abnormal components in the air passing through the purification module 6 cannot be purified and absorbed, the second detection unit 12 can detect it in time, ensuring the quality of the air discharged into the room through the air duct 1. At the same time, the second detection unit 12 has a certain indication function for the purification module 6, and promptly reminds the user whether the purification module 6 needs to be replaced, cleaned or replaced.

[0054] If the first detection unit 11 detects that there is no abnormality in the air composition, the control unit controls the first partition 4 and the second partition 8 to rotate to be flush with the lower bottom surface 18 of the first flow channel 9, thereby closing the air inlet and outlet ends of the second flow channel 10, so that the air does not contact the purification module 6 and is directly discharged through the first flow channel 9. This is the normal air supply mode.

[0055] If the first detection unit 11 detects abnormal air composition, the control unit controls the alarm unit 15 to automatically alarm. At the same time, the control unit controls the first baffle 4 and the second baffle 8 to rotate to contact the upper bottom surface 21 of the first flow channel 9, close the two ends of the first flow channel 9, open the second flow channel 10, and execute the air purification mode. The air enters the second flow channel 10 for air purification.

[0056] If the second detection unit 12 also detects abnormal air composition, it means that the purification module 6 cannot effectively purify the abnormal components in the air. The control unit controls the first partition 4 and the second partition 8 to maintain contact with the upper bottom surface 21 of the first flow channel 9, and continues to close the two ends of the first flow channel 9. The second flow channel 10 remains open. The control unit controls the fan 2 to stop running. At the same time, the control unit controls the alarm unit 15 to make a continuous alarm prompt and execute the alarm mode.

[0057] Preferably, the first detection unit 11 and the second detection unit 12 are configured as gas sensors to accurately detect whether the air passing through the detection units contains abnormal components, thereby improving detection accuracy.

[0058] More preferably, the purification module 6 includes a first filter layer 61, a second filter layer 62, a third filter layer 63, a fourth filter layer 64 and a fifth filter layer 65 in sequence from the air inlet end to the air outlet end. The first filter layer 61 and the fifth filter layer 65 are both configured as activated carbon filter elements, the second filter layer 62 and the fourth filter layer 64 are both configured as activated silicon filter elements, and the third filter layer 63 is configured as an alumina filter element. In this way, the air undergoes multi-stage filtration and can purify a variety of abnormal gases, thereby ensuring that the air containing abnormal gases is fully purified, thereby improving the safety and comfort of the user's indoor living environment.

[0059] Furthermore, the abnormal components described in the present invention include: dangerous gases such as hydrogen sulfide, carbon monoxide, carbon dioxide, formaldehyde, combustible gases, or harmful particulate matter, etc.
