Description
Technical Field
The invention relates to the field of air purification in general, and particularly relates to a fresh air purification system with a remote control function.
Background
Today's air purification systems often employ multiple filter devices, such as multiple layers of filter paper, to filter out various harmful components, such as particulate matter, odor molecules, etc., from the air. However, such air systems often employ high power fans to achieve the desired air filtration rate due to increased wind resistance caused by the provision of excessive filtration devices. However, this causes a problem in that the high-power fan inevitably generates noise, for example, up to 55-60 db, and may cause a problem in heat dissipation.
In addition, the existing air purification system is generally placed indoors and is not communicated with the outside, so that fresh air cannot be introduced. The existing air circulation system with the fresh air function can not flexibly adjust the fresh air quantity between no fresh air and 100 percent fresh air.
In addition, existing air conditioning systems or purification systems typically do not have remote control functionality, such that a user must breathe unclean air for a period of time even if the purification system is turned on immediately after returning home.
Disclosure of Invention
The task of the invention is to provide a fresh air purification system with a remote control function, which can reduce noise and heat dissipation and flexibly adjust fresh air volume between no fresh air (pure internal circulation) and 100% fresh air (forced exhaust circulation), and through the remote control function of the fresh air purification system, a user can start the fresh air purification system in advance and control the operation of the fresh air purification system before reaching a room provided with the fresh air purification system, so that the air in the room reaches the expected temperature and has ideal air quality at the moment when the user reaches the room.
This task is solved through a new trend air purification system who has remote control function, and this new trend air purification system includes:
the air inlet device is provided with an air inlet and an axial flow fan and is used for introducing air into the fresh air purification system;
the air outlet device is provided with an air outlet and a centrifugal fan and is used for discharging air from the air purification system;
the air channel is used for guiding air between the air inlet device and the air outlet device;
an air filtering device arranged in the air duct, the air filtering device being used for filtering air;
fresh air device, it arranges relatively with the air intake, fresh air device includes:
a multi-purpose tuyere communicated to the outside; and
an air volume adjusting plate rotatably disposed in the multipurpose tuyere, wherein the air volume adjusting plate is configured to:
rotating to a closed position in the inner circulation mode to prevent air from being discharged to the outside from the multipurpose outlet; or
The fan is rotated to a half-open position under a fresh air mode so as to introduce air into the fresh air purification system from the outdoor through the multipurpose air opening; and
a remote control device configured to receive remote control commands from a user to enable the user to remotely activate and control operation of the fresh air purification system.
The fresh air purification system with the remote control function at least has the following advantages: (1) noise and heat dissipation are reduced because by using one ventilator at each of the inlet and outlet, the power requirements for each ventilator can be reduced, thereby reducing the power of each of the two ventilators and thus the noise, as compared to using a single ventilator, which is based primarily on the unique recognition by the inventors that the noise generated by the two ventilators is additive, whereas the noise of a single ventilator used to achieve the power (or ventilation capacity) of the two ventilators will be much higher than the sum of the noise of the two ventilators, e.g., 5-10 db higher, and thus the noise will be greatly reduced using two ventilators; (2) the centrifugal fan is adopted at the air outlet, so that the noise can be further reduced, because the centrifugal fan with the same power has larger suction force than the axial flow fan, the axial flow fan with smaller power can be adopted at the air inlet in order to realize the same air circulation speed, and the noise is further reduced; (3) by arranging the air volume adjusting plate at the position opposite to the air inlet, the fresh air volume can be flexibly adjusted between no fresh air (pure internal circulation) and 100 percent fresh air (forced exhaust circulation), which is realized in the invention by the following mode: under the internal circulation mode, the air quantity adjusting plate is completely closed, so that no outdoor air enters the fresh air purification system through the multipurpose air opening, and the effect of pure indoor circulation is realized; in a fresh air mode, the air volume adjusting plate is half-opened, so that air is introduced into the fresh air purification system from the outdoor through the multipurpose air opening, and the fresh air volume can be conveniently adjusted by controlling the opening and closing degree of the air volume adjusting plate; (4) by means of the remote control, the user can remotely start the fresh air purification system and control its operation so that the air of the room has the desired air quality already at the moment the user arrives in the room.

With this extension, remote control can be facilitated for the user, since mobile devices such as cell phones, tablet computers, personal digital assistants or laptop computers are typically carried around by the user and can conveniently access the internet or cellular mobile networks. Furthermore, the authentication means on the existing mobile devices are also reliable, for example, the user can be reliably verified by the authentication means such as TouchID, voice password, character password of apple inc, so as to prevent malicious third parties from remotely operating the fresh air purification system.
In a further embodiment of the invention, it is provided that the fresh air purification system further comprises an air conditioning device, the evaporator of which is arranged in the air duct. Through the expansion scheme, the fresh air purification system has an air conditioning function, and the evaporator of the air conditioning device is directly arranged in the air duct, so that the air conditioning function can be directly realized in the fresh air purification system, and the independent air circulation for the air conditioner is cancelled, so that the electric energy is saved.
In a preferred embodiment of the present invention, it is provided that, in the forced draft mode, the air quantity adjusting plate is rotated to the open position to discharge the air from the air inlet directly to the outside through the multipurpose outlet. Through this preferred scheme, can realize taking a breath fast, because under the forced draft mode, the air regulation board is opened completely for the air that gets into new trend air purification system can be basically directly discharged to the open air through the multipurpose wind gap from the air intake, thereby discharges the indoor air through the multipurpose wind gap fast in order to realize the effect of taking a breath fast.
In a further preferred embodiment of the invention, it is provided that, in the pure fresh air mode, the air inlet is closed and the air volume control plate is rotated into the open position. Through this preferred scheme, can realize pure new trend circulation, under this condition, outdoor air directly gets into new trend air purification system and participates in the air cycle through the multipurpose wind gap.
In a further preferred embodiment of the invention, it is provided that the remote control is further configured to perform at least one of the following actions:
causing the fresh air purification system to enter a pre-purification mode in which an axial fan and a centrifugal fan are operated to filter air within a predetermined time or to reach a predetermined air index, in accordance with the received remote control command;
causing the fresh air purification system to enter a pre-temperature control mode in which an axial flow fan, a centrifugal fan, and an air conditioning device are operated to reach a predetermined temperature, according to the received remote control command;
causing the fresh air purification system to enter a forced-ventilated mode according to the received remote control command;
the fresh air purification system is caused to enter a fresh air mode according to the received remote control command; and
and causing the fresh air purification system to enter a pure fresh air mode according to the received remote control command.
Through the preferred scheme, the fresh air purification system can be remotely controlled to enter various operation modes, such as a pre-purification mode, a pre-temperature control mode, a forced air exhaust mode, a fresh air mode and a pure fresh air mode. Therefore, the user can remotely optimize indoor air parameters, such as increasing the oxygen content through a fresh air mode, a forced air mode and a pure fresh air mode, removing harmful substances through a purification mode, and realizing the appropriate indoor temperature through a temperature control mode, wherein the fresh air mode is suitable for gradually increasing the oxygen content through a small amount of ventilation, and the forced air mode and the pure fresh air mode are both suitable for achieving the purpose of rapidly increasing the oxygen content through a large amount of ventilation. The forced air exhaust mode and the pure fresh air mode are different in that fresh air is introduced from other inlets such as doors and windows in the forced air exhaust mode, so that the ventilation speed of the forced air exhaust mode is higher than that of the pure fresh air mode, and the air inlets in the forced air exhaust mode are more, wherein the introduced fresh air directly enters the indoor without being purified and controlled in temperature; in the pure fresh air mode, fresh air is introduced from the multipurpose air port of the fresh air purification system, so that the air exchange speed is slightly slower than that in the forced exhaust mode, but the introduced fresh air enters the room after being purified and optionally subjected to temperature control. It follows that the forced draft mode is suitable for use when the outdoor air quality is good or for rapid ventilation when remotely controlled (when no one is in the room), while the pure fresh air mode is suitable for use when the outdoor air quality is poor, since the pure fresh air mode can completely isolate the polluted air from the room. The user can flexibly select among these modes to perform remotely according to actual situations.
In one embodiment of the invention, the fresh air cleaning system further comprises a fresh air intake fan which is configured to introduce air from the outside into the air cleaning system when the air volume adjustment plate is rotated into the half-open position.

On the other hand, by directly arranging the centrifugal fan behind the air filtering device, the wind speed passing through the air filtering device can be maximized, thereby increasing the wind resistance of the air filtering device, achieving better filtering effect, because the wind resistance is proportional to the square of the wind speed and proportional to the thickness of the air filtering device, and thus increasing the wind speed will more effectively increase the wind resistance than increasing the thickness of the air filtering device, thereby providing better filtering effect.

Detailed Description
Fig. 1 shows a block diagram of a fresh air purification system 100 with remote control according to the present invention.
The fresh air purification system 100 comprises an air intake device comprising an air inlet 101 and an axial fan 102 for introducing air into the air purification system 100.
The fresh air purification system 100 further comprises an air outlet device, which comprises an air outlet 108 and a centrifugal fan 107, and the air outlet device is used for discharging air from the air purification system 100.
The fresh air purification system 100 further includes an air duct 109, the air duct 109 connects the air inlet device and the air outlet device, and the air duct is used for guiding air between the air inlet device and the air outlet device. In fig. 1, a wind tunnel 109, for example, connects the wind inlet 101 with the wind outlet 108 to guide air. The air duct 109 can have any particular shape, such as cylindrical, prismatic, etc., or can be formed by only sealed walls of the fresh air purification system 100.
The fresh air purification system 100 further comprises a fresh air device disposed opposite to the air inlet 101 and including an air volume adjusting plate 110 and a multipurpose air port 111, for example, in fig. 1, an inlet of the multipurpose air port 111 is disposed opposite to an air outlet of the axial-flow fan 102. The multipurpose tuyere 111 is communicated to the outside of the room, for example, connected to the outside of the room through a pipe. The air quantity adjusting plate 110 is rotatably disposed in the multipurpose tuyere 111 to control the quantity of fresh air introduced into the fresh air purifying system 100 from the outside by rotation. The air volume adjusting plate 110 is configured to: rotated to a closed position in the inner circulation mode so as to prevent air from being discharged to the outside from the multipurpose tuyere 111; and rotated to a half-open position in the fresh air mode to introduce air from outdoors into the fresh air purification system 100 through the multi-purpose air opening 111. In addition, the air volume adjusting plate 110 can also realize an optional forced discharging mode and a pure fresh air mode, which will be explained later. The control of the fresh air volume can be easily achieved by adjusting the opening degree of the air volume adjusting plate 110, wherein the air volume adjusting plate 110 can be driven by a synchronous motor. The inventor finds that when a small angle, for example, an angle of 5 ° to 30 °, especially 10 °, is formed between the air volume adjusting plate 110 and a perpendicular line (i.e., a vertical line in the drawing) from the rotation axis of the air volume adjusting plate 110 to the edge of the multi-purpose air opening 111, that is, when the fresh air volume accounts for 5% -10% of the whole air circulation, a satisfactory indoor air index can be obtained, and at this time, people in a room feel comfortable, so that energy saving is achieved while air quality is ensured. The air quantity adjusting plate 110 is optionally further configured to rotate to an open position in the forced draft mode so as to discharge air from the intake vent 101 directly to the outside through the multipurpose vent 111. By this preferred solution, a rapid ventilation can be achieved. In addition, the air volume adjusting plate 110 can also operate in a pure fresh air mode, at this time, the air inlet 101 is closed, and the air volume adjusting plate 110 rotates to an open position, and under the condition, all the air entering the fresh air purifying system 100 is outdoor air, namely fresh air.
The fresh air purification system 100 further comprises an air filtration device 106, the air filtration device 106 being arranged in the air duct 109, the air filtration device 106 being configured to filter air. In fig. 1, the air outlet direction of the air filter device 106 is parallel to the air inlet direction of the centrifugal fan 107, and the centrifugal fan 107 is arranged such that the air outlet direction of the centrifugal fan 107 is parallel to the opening direction of the air outlet 108. Through such an arrangement, the length of the air duct 109 can be reduced, thereby reducing the power of the ventilators 101 and 108, because the centrifugal ventilator 107 can change the wind direction, i.e. the wind outlet direction thereof is perpendicular to the wind inlet direction thereof, and therefore, through the zigzag arrangement of the air filtering device 106, the centrifugal ventilator 107 and the wind outlet 108, compared with the arrangement in which the three are all in a linear air duct, the length of the air duct can be reduced, thereby reducing the power of the ventilators 101 and 108, and reducing the noise. On the other hand, by arranging the centrifugal fan 107 directly behind the air filtering device 106, the wind speed through the air filtering device 106 can be maximized, thereby increasing the wind resistance of the air filtering device 106, achieving a better filtering effect, because the wind resistance is proportional to the square of the wind speed and proportional to the thickness of the air filtering device 106, and thus increasing the wind speed will increase the wind resistance more effectively than increasing the thickness of the air filtering device 106, thereby providing a better filtering effect 106. It should be noted that the arrangement of the air filtering device 106, the centrifugal fan 107 and the air outlet 108 in fig. 1 is only exemplary, and in other embodiments, the air can be discharged from different directions by changing the arrangement of the three (e.g. rotating the three), for example, from the back or from the front.
In fig. 1, the air filtration device 106 illustratively includes a HEPA high efficiency screen and an activated carbon screen, not specifically shown. The HEPA high-efficiency net is characterized in that the filtering effect on particles with the diameter of 0.1-0.3 mu m is good, and particulate pollutants such as smoke, dust, bacteria and the like can be greatly reduced. Since the activated carbon well adsorbs volatile organic compounds such as formaldehyde, toluene, hydrogen sulfide, chlorobenzene, etc. and other pollutants in the air, the air can be better purified. It should be noted that the use of HEPA high efficiency screens and activated carbon screens is merely exemplary, and in other embodiments, the air filtration device 106 may also include other screens, such as screens for filtering out particles having a particle diameter of 0.1 μm to 2.5 μm.
In fig. 1, the air purification system 100 optionally includes a coarse screen 103 for primary filtering of the air. The coarse screen 103 is preferably arranged in the air flow direction before the evaporator 104 of the air conditioning unit, but other positions are also conceivable. The coarse screen 103 may first filter out large particles in the air, thereby facilitating subsequent fine filtering.
The fresh air purification system 100 optionally further comprises an air conditioning device comprising an evaporator 104 and an outdoor air conditioner 105, wherein the evaporator 104 is arranged in the air duct 109 and the outdoor air conditioner 105 is arranged outdoors. In a preferred aspect, the air conditioning apparatus is a cooling and heating type air conditioner, and the evaporator 104 of the cooling and heating type air conditioner is configured to cool in a cooling mode and convert to a condenser and heat in a heating mode. For a detailed description of the cooling and heating dual-purpose air conditioner, refer to fig. 3. In another preferred embodiment, the air conditioner is a digital variable capacity direct expansion air conditioner. In the direct expansion type air conditioner, the refrigerant directly exchanges heat with air, and intermediate links of indirect heat exchange such as air cooling, water cooling and the like are not needed, so that the loss is reduced.
Furthermore, the fresh air purification system 100 comprises a remote control 112, wherein the remote control 112 may be a separate control module or may be part of a central control unit of the fresh air purification system 100. The remote control device 112 is configured to receive remote control commands from a user to enable the user to remotely start the fresh air purification system 100 and control the operation of the fresh air purification system 100. Thus, the fresh air purification system 100 can be controlled to operate, for example, to purify air, increase the oxygen content of air, or adjust the temperature of the room before the user returns home, and the specific remote control process will be further described in fig. 2. To implement the wireless communication function, the remote control 112 may have a wireless communication module.
The air circulation process in the fresh air purification system 100 with remote control function according to the present invention is explained as follows. In fig. 1, the direction of indoor air circulation is shown by a single arrow.
In the internal circulation mode, under the ventilation effect of the axial-flow fan, air enters the air inlet 101, and because the air volume adjusting plate 110 is completely closed, the air enters the air duct 109 through the axial-flow fan 102. In the air duct 109, the air first passes through the coarse filter screen 103 to filter out large particles in the air, and then optionally passes through an evaporator of an air conditioning device to be conditioned, i.e., heated or cooled, and the conditioned air then travels along the air duct 109 and passes through the air filtering device 106 to filter out fine particles in the air and other harmful substances or impurities; the filtered air then enters the centrifugal fan 107 immediately after the air filtration device 106 and leaves the fresh air purification system 100 from the air outlet 108 after being redirected vertically.
In the fresh air mode, air enters the fresh air purification system 100 from the air inlet 101 under the suction of the axial-flow fan 102, and meanwhile, since the air volume adjusting plate 110 is half-opened (for example, opened by 10 °), outdoor air enters the fresh air purification system 100 through the multipurpose air inlet 111 under the suction of the axial-flow fan 102, and the air flow mixed with the outdoor air enters the air duct 109, and then exits the fresh air purification system 100 from the air outlet 108 through an optional temperature control process and a filtering process.
In the forced-draft mode, air enters the fresh air purification system 100 from the air inlet 101 under the suction force of the axial-flow fan 102, and meanwhile, due to the fact that the air volume adjusting plate 110 is fully opened (for example, opened by 90 °), the air entering through the air inlet 101 is substantially directly discharged to the outside from the multipurpose air outlet 111, so that rapid ventilation is achieved.
In the pure fresh air mode, the air inlet 101 is closed and the air volume adjusting plate 110 is fully opened, so that only outdoor air enters the fresh air purification system 100 through the multipurpose air inlet 111, and pure fresh air circulation is realized. The fresh air mode is suitable for gradually increasing the oxygen content through a small amount of air exchange, and the forced exhaust mode and the pure fresh air mode are both suitable for achieving the purpose of quickly increasing the oxygen content through a large amount of air exchange. The forced air exhaust mode and the pure fresh air mode are different in that fresh air is introduced from other inlets such as doors and windows in the forced air exhaust mode, so that the ventilation speed of the forced air exhaust mode is higher than that of the pure fresh air mode, and the air inlets in the forced air exhaust mode are more, wherein the introduced fresh air directly enters the indoor without being purified and controlled in temperature; in the pure fresh air mode, fresh air is introduced from the multipurpose air port of the fresh air purification system, so that the air exchange speed is slightly slower than that in the forced exhaust mode, but the introduced fresh air enters the room after being purified and optionally subjected to temperature control. It follows that the forced draft mode is suitable for use when the outdoor air quality is good or for rapid ventilation when remotely controlled (when no one is in the room), while the pure fresh air mode is suitable for use when the outdoor air quality is poor, since the pure fresh air mode can completely isolate the polluted air from the room. The user can flexibly select among these modes to perform remotely according to actual situations.
The fresh air purification system 100 with remote control function according to the present invention has at least the following advantages: (1) noise and heat dissipation are reduced because by using one ventilator 102 and 107 at the inlet 101 and outlet 108, respectively, the power requirements for each ventilator 102 and 107 can be reduced, thereby reducing the ventilator power and hence noise, compared to using a single ventilator, which is based primarily on the unique recognition by the inventors that the noise generated by two ventilators is additive, whereas the noise of a single ventilator used to achieve the power (or ventilation capacity) of two ventilators will be much higher than the sum of the noise of the two ventilators, e.g. 5-10 db higher, and hence the noise will be greatly reduced using two ventilators; (2) by adopting the centrifugal fan 107 at the air outlet 108, the noise can be further reduced because the centrifugal fan with the same power has a larger suction force than the axial fan, so that the axial fan with smaller power can be adopted at the air inlet in order to realize the same air circulation speed, thereby further reducing the noise; (3) by arranging the air volume adjusting plate 110 at a position opposite to the air inlet 101, the fresh air volume can be flexibly adjusted between no fresh air (pure internal circulation) and 100% fresh air (forced exhaust circulation), which is realized in the invention by the following way: in the internal circulation mode, the air volume adjusting plate 110 is completely closed, so that no outdoor air enters the fresh air purification system 100 through the multipurpose air opening 111, and the effect of pure indoor circulation is realized; in the fresh air mode, the air volume adjusting plate 110 is half-opened, so that air is introduced into the fresh air purification system 100 from the outside through the multipurpose air opening 111, and the fresh air volume can be conveniently adjusted by controlling the opening and closing degree of the air volume adjusting plate 110; (4) by means of the remote control 112, the user can remotely activate the fresh air purification system 100 and control its operation such that the air of the room has reached the desired temperature and has the desired air quality at the moment the user arrives in the room.
Fig. 2 shows an operating environment 200 of the fresh air purification system 100 with remote control according to the present invention.
In fig. 2, the fresh air purification system 100 is connected to a router 204 through a wireless connection 207, the wireless router 204 in turn being connected to the internet 203. It should be noted here that this connection is merely exemplary, and in other embodiments, the fresh air purification system 100 may access the internet 203 via a wired connection, or communicate directly with the user's mobile device 201 via a mobile cellular connection.
A user's mobile device 201, e.g. a smartphone, is connected to the internet 203 via a wireless connection 205. It should also be noted here that this manner of connection is merely exemplary, and in other embodiments, the user's mobile device 201 may communicate directly with the fresh air purification system 100 via a cellular mobile connection.
A mobile device application 202 is installed on the user's mobile device 201, through which mobile device application 202 the user can input remote control commands which are transmitted to the fresh air purification system 100 via the internet 203 or a mobile cellular network in order to remotely start up and control the operation of the fresh air purification system 100.
To ensure security, a verification server 206 is optionally provided, which is configured to authenticate the user. For example, the user enters user credentials such as a fingerprint, password, etc. into the mobile device application 202 and the user credentials are then transmitted to the verification server 206 to verify it, and only after the user authentication is successful can the user's mobile device connect to and communicate with the fresh air purification system 100, otherwise the user is denied control access to the fresh air purification system 100. By using the verification server 206, security may be improved, preventing malicious third parties from remotely manipulating the fresh air purification system 100. In addition, when the user uses the mobile device application 202 for the first time, the mobile device application 202 and the fresh air purification system 100 may be paired, for example, the user may input a unique identification code provided by a manufacturer of the fresh air purification system 100 into the mobile device application 202 to complete the pairing between the mobile device application 202 and the fresh air purification system 100, and after the pairing is successful, the mobile device application 202 may be used to remotely control the fresh air purification system 100. Other pairing approaches are also contemplated, such as by obtaining a short message passcode or a dynamic password in an appropriate manner (e.g., obtaining a passcode or dynamic password from the public office to bind the cell phone to the fresh air purification system 100) and entering it into the mobile device application 202 to complete the provisioning, etc.
On the mobile device application 202, a user may enter a variety of remote control commands to cause the fresh air purification system 100 to start up and enter different modes of operation. For example, in the pre-purification mode, the axial fan 101 and the centrifugal fan 107 are operated to filter air for a predetermined time or to reach a predetermined air index, wherein the user can set the time or air index for air purification through the mobile device application 202, such as setting the required oxygen content, PM index, etc., to be reached, and then the fresh air purification system 100 is operated remotely until the index is reached. In this case, the fresh air purification system 100 is equipped with an air quality sensor for detecting air indicators such as air oxygen content, air particles, and the like. In the pre-temperature control mode, the axial fan 101, the centrifugal fan 107 and the air conditioning device are operated to reach a predetermined temperature, and a user can set the temperature to be reached through the mobile device application 201, wherein the fresh air purification system 100 is remotely operated until the temperature is reached, and then enters the energy saving mode or the intermittent operation mode to maintain the temperature. In addition, the user may also input a remote control command to cause the fresh air purification system 100 to enter a fresh air mode, a forced air mode, or a pure fresh air mode.
Fig. 3A and 3B illustrate the operation principles of heating in summer and heating in winter of the air conditioner for both cooling and heating purposes, respectively. The refrigeration principle is as follows (see fig. 3A): after the air conditioner is powered on, the low-pressure steam of the refrigerant is sucked by the compressor 304 and compressed into high-pressure steam, and then the high-pressure steam is discharged to the condenser 301; meanwhile, outdoor air sucked by the fan flows through the condenser 301 to take away heat emitted by the refrigerant, so that high-pressure refrigerant vapor is condensed into high-pressure liquid. The high pressure liquid enters the evaporator after passing through the filter (not shown) and the throttling device 305, and is evaporated at a corresponding low pressure, absorbing ambient heat; meanwhile, the fan continuously introduces air into the evaporator 302 for heat exchange, and sends the air that has released heat and become cold to the room. Thus, the indoor air continuously circulates and flows to achieve the purpose of reducing the temperature. The heating principle of the cooling and heating dual-purpose air conditioner (see fig. 3B) is the reverse of the cooling principle, except that the original evaporator 302 serves as the condenser 302 'and the original condenser 301 serves as the evaporator 301'.
