Description

New fan of many mode
Technical Field
The invention belongs to the technical field of indoor air purification, and particularly relates to a multi-working-mode fresh air machine.
Background
The fresh air machine is the air purification equipment which is very commonly used at present, and can introduce and filter outdoor air and send the air into a room. Traditional new fan is one-way positive pressure formula, and new fan only can send into the new trend indoor promptly to developments keep indoor atmospheric pressure to outdoor pressure a little, and indoor air then passes through the door and window gap and outwards escapes, and the function is comparatively single.
Therefore, bidirectional fresh air fans gradually appear in the market, and the fresh air fans can introduce outdoor fresh air into a room and discharge indoor foul air out of the room. The new fan comprises a shell, wherein an exhaust channel and a new air channel are arranged in the shell, the new air channel is provided with a new air filtering inlet and a new air outlet which are formed on the shell, and the new air fan is fixedly arranged in the shell and used for providing power for guiding new air from the new air filtering inlet to the new air outlet; the air exhaust channel is provided with an air exhaust inlet and an outdoor air inlet and outlet which are formed on the machine shell, an air exhaust fan is fixedly arranged in the machine shell, and the air exhaust fan is used for providing power for guiding waste air from the air exhaust inlet to the outdoor air inlet and outlet. A first exhaust branch and a second exhaust branch communicated with the two ends of the exhaust channel are formed in the exhaust channel, and a first fresh air branch and a second fresh air branch communicated with the two ends of the fresh air channel are formed in the fresh air channel; the shell is internally provided with a heat exchanger which is connected to the first exhaust branch and the first fresh air branch to exchange heat between the waste air and the fresh air; the air exhaust channel and the fresh air channel are also provided with reversing valves, the reversing valves can be switched to a first state or a second state, respond to the switching of the states and conduct the first air exhaust branch and the first fresh air branch and cut off the second air exhaust branch and the second fresh air branch, or cut off the first air exhaust branch and the first fresh air branch and conduct the second air exhaust branch and the second fresh air branch.
The existing new fan has the following defects: (1) Besides a fresh air channel and a fresh air fan, an independent exhaust channel and an independent exhaust fan are additionally arranged in the shell to realize the function of exhausting indoor waste gas to the outside, and the exhaust channel and the fresh air channel exist simultaneously, so that the volume of the whole machine is doubled, and the operation energy consumption of the fresh air fan is increased; (2) When the fresh air fan and the exhaust fan work simultaneously, in order to prevent fresh air entering a room from being sucked into the exhaust inlet in a short time, the distance between the fresh air outlet and the exhaust inlet needs to be set to be far as possible, and even pipelines need to be installed at the fresh air outlet or the exhaust inlet so as to extend the fresh air outlet and the exhaust inlet to different spatial positions, so that the shell volume is further increased, and even the indoor space is occupied; the fresh air fan and the exhaust fan do not work simultaneously, so that the problem that fresh air is exhausted in a short time can be avoided, but the volume of the fresh air is still increased greatly; (3) The air purifier can only be used for sending filtered fresh air into a room, but the filtered fresh air has less air volume because of passing through a filter element; in some special cases, a large amount of fresh air cannot be directly sent into the room to accelerate air circulation.
Disclosure of Invention
The invention aims to provide a multi-working-mode fresh air fan which not only has a fresh air (filtering) introducing function, a fresh air direct blowing function and a waste air discharging function, but also has smaller integral volume and low operation energy consumption.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a multi-working-mode fresh air fan comprises a shell, wherein a fresh air filtering inlet facing outdoors, an outdoor air inlet and outlet and an indoor air inlet and outlet facing indoors are formed in the shell, and a filtering component is arranged at the fresh air filtering inlet;
the shell internal rotation be connected with the mechanism of blowing, should blow the mechanism and have shutoff outdoor wind access & exit and lead the new trend of new trend to indoor wind access & exit department from new trend filtration entry and draw into the position, directly blow the position with new trend that leads indoor wind access & exit to and lead the exhaust air exhaust position of outdoor wind access & exit to the exhaust air of indoor wind access & exit.
In the invention, one side of the shell facing the indoor is only provided with an indoor air inlet and outlet which can be used as a fresh air outlet and an exhaust air inlet; one side which can face the outdoor is provided with a fresh air filtering inlet and an outdoor air inlet and outlet which can be used as an exhaust outlet and a fresh air direct blowing inlet; meanwhile, the blowing mechanism is rotatably connected in the shell, and the blowing mechanism can reach a corresponding working position when rotating relative to the shell, so that different airflow channels are formed in the fresh air machine.
When fresh air is required to be introduced into a room for filtering, the blowing mechanism rotates to block an outdoor air inlet and outlet, and under the suction of the blowing mechanism, outdoor fresh air can only pass through the fresh air filtering inlet and is filtered by the filtering assembly and then enters the room from the indoor air inlet and outlet to form a fresh air filtering passage, and at the moment, the fresh air fan is positioned in a fresh air introducing position; when fresh air needs to be rapidly introduced into a room to drive indoor air to circulate, the blowing mechanism rotates to ensure that an outdoor air inlet and outlet is not blocked, and because no filtering component is arranged at the outdoor air inlet and outlet, outdoor fresh air can easily enter the room from the outdoor air inlet and outlet through the indoor air inlet and outlet to form a fresh air direct blowing passage, and at the moment, the blowing mechanism is positioned at a fresh air direct blowing position; when the indoor waste air is required to be discharged to the outdoor, the blowing mechanism rotates to enable the outdoor air inlet and outlet not to be blocked, the indoor waste air enters the fresh air machine from the indoor air inlet and outlet and flows out of the outdoor air inlet and outlet to the outdoor under the suction of the blowing mechanism to form an air exhaust passage, and the blowing mechanism is located at a waste air discharge position.
Obviously, in the fresh air introducing position and the fresh air direct blowing position, the wind directions of the blowing mechanisms introduce outdoor wind into the room; and in the waste air discharge position, the wind direction of the blowing mechanism is opposite.
The invention only sets one blowing mechanism, even if the fresh air machine has different functions, the fresh air can be introduced into the room after being filtered, the fresh air can be directly blown into the room to accelerate the indoor air circulation, and the indoor waste air can be discharged out of the room, thereby not only saving the power cost and reducing the operation energy consumption, but also reducing the volume of the fresh air machine.
Moreover, in the new fan, the new trend filters the route, the new trend directly blows the route and air exhaust between the route not independent setting, and also not parallel simultaneously, but overlap each other and form in turn, only need to change the circumferential position of the mechanism of blowing in the casing and blow the direction and can switch the air current route in the new fan, so make the whole volume of new fan design littleer.
In the above-mentioned new fan of many mode, blow mechanism include:
the wind direction regulating and controlling device comprises a wind direction regulating and controlling housing and a first circumferential driver, wherein the wind direction regulating and controlling housing is rotatably arranged in a shell;
the wind wheel is rotatably arranged in the wind direction regulating and controlling housing, and the second circumferential driver is used for driving the wind wheel to rotate in two directions;
an air suction port and an air supply port which are positioned at the periphery of the wind wheel are formed on the wind direction regulating and controlling housing, a fresh air filtering passage is formed among the fresh air filtering inlet, the air suction port, the air supply port and the indoor air inlet and outlet, a fresh air direct blowing passage is formed among the outdoor air inlet and outlet, the air suction port, the air supply port and the indoor air inlet and outlet, and an air exhaust passage is formed among the indoor air inlet and outlet, the air suction port, the air supply port and the outdoor air inlet and outlet;
the wind direction regulating cover shell at the fresh wind introducing position seals the outdoor wind inlet and outlet so that the wind wheel filters the outdoor fresh wind through the fresh wind filtering passage and then enters the room, the wind direction regulating cover shell at the fresh wind direct blowing position opens the outdoor wind inlet and outlet so that the wind wheel directly blows the outdoor fresh wind into the room through the fresh wind direct blowing passage, and the wind direction regulating cover shell at the waste wind discharging position opens the outdoor wind inlet and outlet so that the indoor waste wind is discharged to the outside through the air discharging passage;
the first circumferential driver and the second circumferential driver are both connected with a control module, and the control module controls the first circumferential driver and the second circumferential driver to work according to instructions so as to cut off or communicate a fresh air filtering passage, a fresh air direct blowing passage or an air exhausting passage.
The wind wheel and the wind direction regulation and control housing are respectively provided with an independent circumferential driver, and the wind wheel and the wind direction regulation and control housing can independently work according to the control instruction of the control module without mutual influence. The wind wheel is rotatably connected in the wind direction regulating and controlling housing, and the second circumferential driver can drive the wind wheel to rotate in two directions (forward rotation or reverse rotation) to attract air so as to determine the approximate guiding direction of the fresh air fan to the airflow (so that fresh air enters the room from the outside or waste air is discharged out of the room from the room); the wind direction regulating cover shell is driven by the first circumferential driver to rotate relative to the casing, so that the air suction opening and the air supply opening respectively reach different working positions to assist the wind wheel in regulating the air flow direction.
When fresh air needs to be introduced, the wind direction regulating and controlling housing rotates according to the instruction of the control module, so that the air supply outlet reaches the position opposite to the indoor wind inlet and outlet, at the moment, the wind direction regulating and controlling housing can just block the outdoor wind inlet and outlet, the fresh air filtering passage is communicated, the fresh air direct blowing passage and the air exhaust passage are cut off, and the outdoor fresh air enters the indoor space through the fresh air filtering passage under the suction of the wind wheel (the wind wheel rotates in the positive direction); when fresh air needs to be quickly introduced into a room to drive indoor air to circulate, the wind direction regulating and controlling housing rotates according to the instruction of the control module, so that the air supply outlet is still communicated with the indoor wind inlet and outlet while the outdoor wind inlet and outlet are not blocked (completely not blocked or partially blocked), and the outdoor fresh air enters the room through the fresh air direct blowing passage under the suction of the wind wheel (the wind wheel rotates positively); when the indoor waste air needs to be exhausted, the wind direction regulating and controlling cover shell rotates according to the instruction of the control module, so that the air supply outlet reaches the position opposite to the outdoor air inlet and outlet, the air exhaust passage is communicated at the moment, and the indoor waste air is exhausted out of the room through the air exhaust passage under the suction of the wind wheel (the wind wheel rotates reversely).
Obviously, the forward rotation and the reverse rotation of the wind wheel are only relative, and the invention has no special requirement on the specific steering of the wind wheel under different working states; meanwhile, the wind direction regulating and controlling cover can rotate 360 degrees in the casing, and the wind direction regulating and controlling cover has no special requirement on the steering of the wind direction regulating and controlling cover.
In the invention, the instruction received by the control module can be sent by a user control operation panel or a remote controller, or can be generated by the control module after receiving and comparing monitoring data sent by an environment monitoring module connected with the control module; the environment monitoring module can monitor indoor and outdoor environment states in real time and send monitoring results to the control module, and the control module compares indoor numerical values and outdoor numerical values of the same environmental parameters and automatically generates corresponding instructions according to comparison results.
Under the fresh air introducing position and the fresh air direct blowing position, the circumferential position of the wind direction regulating and controlling housing relative to the casing is changed, but the air supply outlet is communicated with the indoor wind inlet and outlet all the time to supply air to the indoor. In order to ensure that two working states are feasible, in the multi-working-mode fresh air fan, the circumferential width of the indoor air inlet and outlet is larger than the circumferential width of the air supply outlet, the air supply outlet at the fresh air introducing position and the air supply outlet at the fresh air direct blowing position are respectively positioned at different circumferential positions of the indoor air inlet and outlet, and the two circumferential positions are not overlapped or partially overlapped.
In the multi-working-mode fresh air fan, the circumferential width of the air suction opening is greater than the circumferential width of the fresh air filtering inlet or the indoor air inlet and outlet, and a radial air passing gap which is convenient for air flow to radiate from the fresh air filtering inlet or the indoor air inlet and outlet to the air suction opening is formed between the wind direction regulating and controlling housing and the casing;
the periphery of the wind direction regulating and controlling housing is provided with a first plugging piece which is positioned in the radial overfire air gap and is used for plugging the outdoor wind inlet and outlet under the fresh wind introduction position.
The circumferential widths of the fresh air filtering inlet and the indoor air inlet and outlet are greatly limited by the shape of the outer side surface of the machine shell (mostly a plane or a cambered surface with a small radian), and the circumferential width of the exhaust inlet can be set to be larger because the exhaust inlet is arranged on the circumferential surface of the wind direction regulating and controlling housing so as to increase the air inlet amount; in order to facilitate the air flow to radiate to the air suction opening from the fresh air filtering inlet or the indoor air inlet and outlet, the air direction regulating and controlling housing does not contact with the casing in the whole circumferential direction, but a radial air passing gap is reserved, and a first plugging piece is additionally arranged on the periphery of the air direction regulating and controlling housing so as to plug the outdoor air inlet and outlet under the fresh air introducing position.
In the multi-working-mode fresh air machine, the periphery of the wind direction regulating and controlling housing is further provided with a second blocking piece located in the radial air passing gap, a first air passing opening corresponding to the position of the air supply opening is formed in the second blocking piece, and the second blocking piece is in sealing contact with the outer edges of the opening of the air supply opening, the opening of the indoor air inlet and the opening of the outdoor air inlet and outlet at the outer edge of the opening of the first air passing opening so as to prevent air leakage.
Because a radial air passing gap is separated between the air supply outlet and the indoor air inlet and outlet (under the fresh air introduction position) and between the air supply outlet and the outdoor air inlet and outlet (under the waste air discharge position), in order to prevent fresh air or waste air from flowing into the radial air passing gap from the air supply outlet, the periphery of the wind direction regulating and controlling housing is also provided with a second plugging piece, and the second plugging piece can plug the radial air passing gap outside the air supply outlet so that the fresh air or the waste air only passes through the first air passing outlet from the air supply outlet and enters the indoor air inlet and outlet or the outdoor air inlet and outlet, and the air leakage phenomenon can not occur, thereby achieving the purpose of centralized air supply.
In the multi-working-mode fresh air machine, the wind direction regulating and controlling housing is further provided with a third plugging piece located in the radial overfire gap, and the blowing mechanism is provided with a closing position enabling the third plugging piece to plug the outdoor wind inlet and outlet and enabling the second plugging piece to plug the indoor wind inlet and outlet.
When the blowing mechanism is in a closed position, the second plugging piece completely plugs the indoor air inlet and outlet, the first air passing opening is not exposed at the indoor air inlet and outlet, and the third plugging piece plugs the outdoor air inlet and outlet (note that when the first plugging piece plugs the outdoor air inlet and outlet, the first air passing opening is exposed at the indoor air inlet and outlet); when the blowing mechanism is in the closed position, the new fan can stop working, and outdoor dust is prevented from entering the room when the new fan is stopped.
In the multi-working-mode fresh air machine, the wind direction regulating and controlling housing comprises a left housing and a right housing, wherein one side of the left housing and the other side of the right housing are detachably and fixedly connected through a first sealing piece, and the other side of the left housing and the other side of the right housing are detachably and fixedly connected through a second sealing piece;
the air supply opening is formed between the left housing and the right housing and is symmetrically arranged with the first plugging piece relative to the central axis of the wind direction regulating housing, and the circumferential width of the first plugging piece is smaller than that of the indoor wind inlet and outlet so as to prevent the indoor wind inlet and outlet from being plugged at the waste wind discharge position.
According to the invention, the wind direction regulating and controlling housing is separately arranged into the left housing and the right housing, and the first plugging piece and the second plugging piece can be just used on the opposite two sides of the left housing and the right housing to play a role in connecting the left housing and the right housing, so that the assembly and the overhaul of the wind direction regulating and controlling housing and the overhaul of the wind wheel are more convenient.
Because the air supply outlet is respectively aligned with the indoor air inlet and the outdoor air inlet and outlet under the fresh air introducing position and the waste air discharging position, and the first plugging piece is aligned with the outdoor air inlet and outlet under the fresh air introducing position, in order to facilitate the control module to control the first circumferential driver, the positions of the first plugging piece and the air supply outlet are set to be symmetrical about the central axis of the wind direction regulating and controlling housing; meanwhile, in order to avoid the first blocking piece from blocking the indoor air inlet and outlet under the waste air discharge position, the circumferential width of the first blocking piece is set to be smaller than that of the indoor air inlet and outlet.
In the multi-working-mode fresh air blower, the circumferential width of the air suction opening is greater than the circumferential width of the air supply opening so as to facilitate large-amount air suction and centralized air supply;

In the invention, the circumferential width of the air suction opening is larger, so that the wind wheel can suck a large amount of air, and the working efficiency is improved; the circumferential width of the air supply outlet is relatively small, so that concentrated air supply at a certain circumferential position of the casing is facilitated, and the volume of the casing can be correspondingly reduced.
Because the relative position of supply-air outlet needs to set up first shutoff piece, consequently inlet scoop and supply-air outlet's position is adjacent. Because the distance between the two is relatively close, the wind wheel can not directly lead the air to the air supply opening from the air suction opening in a short distance and in a large amount, and an air guide channel needs to be additionally arranged, so that the air suction opening is only arranged on one side of the air supply opening to reserve a space for the arrangement of the air guide channel.
In the invention, the air guide channel starts from the air suction opening, bypasses the opposite side of the air suction opening of the wind wheel route and then reaches the end of the air supply opening; under the centrifugal action of the wind wheel, the airflow is accelerated by the wind guide channel and then leaves the wind direction regulating and controlling housing from the air supply opening.
In order to block short-distance ventilation between the air suction opening and the air supply opening, the wind shielding piece is arranged on the wind direction regulating and controlling cover shell.
Preferably, in the multi-operation-mode fresh air blower, a front end of the wind shielding member extends towards the wind wheel, and is formed with a wind shielding surface facing the air suction opening to prevent the air flow from directly entering the air supply opening from the air suction opening, and a first wind guiding surface facing the air supply opening to guide the air flow in the wind guiding channel into the air supply opening;
the air supply opening is provided with an air guide grid, and at least two second air guide surfaces which are positioned on different circumferential positions of the air supply opening are formed on the air guide grid to dispersedly supply air.
The front end of the wind shielding piece extends to the wind wheel to form a partition between the air suction opening and the air supply opening, and the wind shielding surface facing the air suction opening can prevent the air flow from flowing to the air supply opening from the air suction opening and guide the air flow to the wind wheel; since the air supply opening is not directly opposite to the terminal of the air guide channel, the wind shield has a first air guide surface facing the air supply opening, the first air guide surface plays a role of guiding the air flow in the air guide channel into the air supply opening, and the first air guide surface is preferably in an arc shape.
Meanwhile, an air guide grid is arranged at the air supply opening, and a second air guide surface on the air guide grid and the first air guide surface relay the air flow to the air supply opening. And each second air guide surface is positioned on different circumferential positions of the air supply opening, so that the air flow from the air guide channel is uniformly supplied to each circumferential position of the air supply opening to distribute air supply.
The air guide grille can be arranged at the first air passing opening of the second plugging piece and extends towards the air supply opening, so that the second air guide surface is in butt joint with the air guide channel.
In the multi-working-mode fresh air machine, the casing comprises a main case, a support is fixedly arranged in the main case, the blowing mechanism is rotatably connected in the support, a heat dissipation gap is reserved between the support and the main case, and a heat dissipation port communicating the inner space of the support with the heat dissipation gap is formed in the support;
a second air passing port corresponding to the indoor air inlet and outlet is formed in the support, a wind shielding convex edge extending into the indoor air inlet and outlet is arranged on the outer edge of an opening of the second air passing port, and the wind shielding convex edge is in sealing fit with the inner peripheral wall of the indoor air inlet and outlet;

In the invention, the blowing mechanism is not directly contacted with the main case, but is separated by the bracket and the heat dissipation gap, thereby being beneficial to the heat dissipation of the blowing mechanism. Meanwhile, the bracket is provided with a wind shielding convex edge which is in sealing fit with the inner peripheral wall of the indoor air inlet and outlet, so that airflow can directly pass through the second air passing opening and the indoor air inlet and outlet and can not enter the heat dissipation gap through the gap between the second air passing opening and the indoor air inlet and outlet.
According to the invention, the fresh air outlet and the outdoor air inlet and outlet are arranged on the filtering mechanism which is detachably and fixedly connected with the main casing, and the first filtering piece is also detachably arranged on the filtering casing, so that the first filtering piece does not occupy the internal space of the fresh air machine, the distance between the first filtering piece and the fresh air filtering inlet is short, the fresh air which is not filtered only passes through the filtering casing and does not enter the fresh air machine, and the cleaning and maintenance cost of the fresh air machine is reduced; only need to filter the casing and dismantle from the new trend fan main part, can filter the entry to the new trend, outdoor wind access & exit and clean, removable second filters the piece simultaneously, has simplified the clearance procedure greatly.

As shown in fig. 14, as can be seen from fig. 3 and 4, the blowing mechanism 2 of the present embodiment includes a wind direction regulating cover 21 rotatably installed in the bracket 15, and a first circumferential driver 22 for driving the wind direction regulating cover 21 to rotate. The first circumferential driver 22 adopted in this embodiment is a stepping motor, the stepping motor is detachably mounted at the bottom of the support 15, and an output shaft of the stepping motor passes through the support 15 and then is fixedly connected with the wind direction regulating housing 21.
A wind wheel 23 is rotatably mounted in the wind direction regulating housing 21, and two ends of a central shaft of the wind wheel 23 are rotatably connected with an end cover 13 of the wind direction regulating housing 21 through bearings; moreover, one end of the central shaft extends out of the wind direction regulating and controlling housing 21 and is fixedly connected with an output shaft of the second circumferential driver 24, and the second circumferential driver 24 adopted in the embodiment is a motor.
The wind direction regulating cover 21 is detachably mounted with a driving cover 25 covering the second circumferential driver 24, at this time, the bottom end of the wind direction regulating cover 21 is directly rotatably connected with the bracket 15 through the rotating lubricant 26, and the top end of the wind direction regulating cover 21 is rotatably connected with the bracket 15 through the rotating lubricant 26 by the driving cover 25.
As shown in fig. 14, the wind direction regulating cover 21 of the present embodiment includes a left cover 211 and a right cover 212, and each of the left cover 211 and the right cover 212 has a substantially arc-shaped cross section; one side of the left cover 211 and the right cover 212 is detachably and fixedly connected through a first blocking piece 27, and the other side of the left cover 211 and the right cover 212 is detachably and fixedly connected through a second blocking piece 28, so that a wind wheel accommodating space is finally surrounded.
As shown in fig. 15, 16, 17 and 18, in conjunction with fig. 14, the removable connection between the first and second closeouts 27, 28 and the left and right housing shells 211, 212 is: a row of buckling parts 213 are integrally formed on both sides of the left cover 211 and the right cover 212, and a buckling groove 213a is formed on each buckling part 213; two rows of hook-shaped portions 271 are integrally formed on the first blocking member 27, two rows of hook-shaped portions 281 are integrally formed on the second blocking member 28, the positions of the hook-shaped portions 213 correspond to those of the hook-shaped portions one by one, and the left housing 211 and the right housing 212 can be fixedly connected together by placing the hook-shaped portions into the corresponding fastening grooves 213 a.
In this embodiment, the wind direction regulating cover 21 has an air inlet 211a formed on the left cover 211 and an air outlet 212a formed between the left cover 211 and the right cover 212, and the second blocking element 28 has a first air passing opening 282 corresponding to the air outlet 212 a; obviously, the outer edge of the opening of the first air passing opening 282 and the outer edge of the opening of the air supply opening 212a are in sealing contact, and no air leakage occurs between the two. The first closing member 27 is located opposite to the air blowing port 212 a.
As shown in fig. 20 and 21, the circumferential width of the fresh air filtering inlet 511 and the indoor air inlet/outlet 111 is greatly limited by the shape of the outer side surface of the casing 1 (mostly, a plane or a cambered surface with a small radian), and the circumferential width of the air suction inlet 211a can be set larger by setting the circumferential surface of the wind direction regulating housing 21, so as to increase the intake air volume of the wind wheel 23; in order to facilitate the air flow from the fresh air filtering inlet 511 or the indoor air inlet/outlet 111 to the air suction inlet 211a, the wind direction regulating housing 21 is not in contact with the casing 1 along the entire circumference, but a radial air gap 6 is left.
However, the existence of the radial air gap 6 is not favorable for regulating the air flow direction, so that the first blocking piece 27 and the second blocking piece 28 are arranged on the periphery of the wind direction regulating cover 21, and the first blocking piece 27 and the second blocking piece 28 are used for limiting the air flow direction at proper time besides being used for connecting the left cover piece 211 and the right cover piece 212.
The first blocking member 27 is used for blocking the outdoor wind inlet/outlet 512 at an appropriate time, and the second blocking member 28 is used for being in sealing contact with the second air passing opening 172 or the opening outer edge of the outdoor wind inlet/outlet 512 at an appropriate time to prevent the air flow from the first air passing opening 282 into the radial air passing gap 6.
Since the wind direction control housing 21 can rotate relative to the casing 1, the positions of the air suction port 211a and the air supply port 212a can be moved, so that the wind direction control housing 21 is in different working states.
As shown in fig. 19 and 20, when fresh air needs to be filtered and introduced into the room, the wind direction regulating housing 21 rotates to enable the first blocking piece 27 to block the outdoor wind inlet/outlet 512, at this time, the second blocking piece 28 is in sealing contact with the outer edge of the opening of the second air passing opening 172 at the outer edge of the opening of the first air passing opening 282, so that the airflow directly flows from the air supply opening 212a to the indoor wind inlet/outlet 111, under the suction of the wind wheel 23 (at this time, the wind wheel 23 rotates forward), the outdoor fresh air can only enter the fresh air machine through the fresh air filtering inlet 511, and after being filtered by the first filter 53, the fresh air sequentially flows through the air suction opening 211a, the wind wheel 23, the air supply opening 212a, the first air passing opening 211a, the wind wheel 23 air guide channel 212b, the air supply opening 212a, the first air passing opening 282, the second air passing opening 172 and the indoor wind inlet/outlet 111, and is sequentially communicated with each other, so as to form a fresh air filtering passage; at this time, the indoor wind inlet/outlet 111 serves as a fresh wind outlet, and the wind direction control housing 21 is located at a fresh wind introduction position.
As shown in fig. 23 and 24, when fresh air needs to be introduced into the room quickly to accelerate air circulation, the wind direction regulating housing 21 is rotated to prevent the first blocking piece 27 from blocking the outdoor wind inlet/outlet 512 (it may be not blocked at all or partially blocked); because the circumferential width of the indoor air inlet/outlet 111 (and the second air passing opening 172) is greater than the circumferential width of the air supply opening 212a (and the first air passing opening 282), even if the position of the first blocking piece 27 is deviated, the air supply opening 212a is still communicated with the indoor air inlet/outlet 111, and at this time, the outdoor air inlet/outlet 512, the air suction opening 211a, the wind wheel 23, the air supply opening 212a, the first air passing opening 282, the second air passing opening 172 and the indoor air inlet/outlet 111 are sequentially communicated to form a fresh air direct blowing passage; because the first filtering piece 53 is not arranged at the outdoor air inlet/outlet 512, outdoor fresh air can easily enter the room through the fresh air direct-blowing passage from the outdoor air inlet/outlet 512, at the moment, the outdoor air inlet/outlet 512 is used as a fresh air direct-blowing inlet, and the wind direction regulating housing 21 is positioned at a fresh air direct-blowing position.
As shown in fig. 21 and 22, when the indoor waste air needs to be discharged to the outdoor, the wind direction regulating cover 21 rotates to make the supply port 212a align with the outdoor wind inlet/outlet 512, at this time, the second blocking piece 28 is in sealing contact with the opening outer edge of the outdoor wind inlet/outlet 512 at the opening outer edge of the first air inlet 282, and the first blocking piece 27 is opposite to the indoor wind inlet/outlet 111, but because the circumferential width of the first blocking piece 27 is smaller than the circumferential width of the indoor wind inlet/outlet 111, the first blocking piece 27 cannot block the indoor wind inlet/outlet 111, at this time, the wind wheel 23 rotates reversely under the suction of the wind wheel 23, the indoor waste air sequentially flows through the indoor wind inlet/outlet 111, the second air inlet 172, the suction port 211a, the wind guiding channel 212b of the wind wheel 23, the supply port 212a, the first air inlet 282 and the outdoor wind inlet/outlet 512, and is discharged to the outdoor, and the indoor wind inlet/outlet 111, the second air inlet/outlet 172, the suction port 211a, the wind guiding channel 212b, the supply port 282, the first air inlet/outlet 282 and the outdoor wind guiding channel 512 are sequentially communicated with each other to form an outdoor wind guiding channel 512; at this time, the indoor air inlet/outlet 111 serves as an exhaust air inlet, the outdoor air inlet/outlet 512 serves as an outdoor air inlet/outlet, and the wind direction control housing 21 is in the waste air exhaust position.
In the embodiment, the fresh air filtering channel, the fresh air direct blowing channel and the air exhaust channel are not independently arranged, are not parallel at the same time, are overlapped and can be switched mutually, the cutting off or the communication of different air flow channels can be realized only by changing the circumferential position and the blowing direction of the blowing mechanism 2 in the shell 1, and the whole volume of the fresh air fan can be designed to be smaller.
As shown in fig. 25 and 26, the outer peripheral wall of the right casing 212 is further provided with a third blocking member 210 in the radial air passing gap 6, and the wind direction regulating casing 21 further has a third operating state: and a closed position.
As shown in fig. 25, when the wind direction control housing 21 is in the closed position, the second blocking piece 28 completely blocks the indoor wind inlet/outlet 111, and at this time, the first air passing opening 282 is not exposed at the indoor wind inlet/outlet 111, and at the same time, the third blocking piece 210 blocks the outdoor wind inlet/outlet 512; so when new fan stop work, no matter be indoor air or outdoor air can not get into in the new fan.
Obviously, the forward rotation and the reverse rotation of the wind wheel 23 are only relative, and the invention has no special requirement on the specific steering of the wind wheel 23 under different working conditions; meanwhile, the wind direction regulating cover 21 can rotate 360 degrees in the machine shell 1, and the invention has no special requirement on the steering.
In the blowing mechanism 2, the first circumferential driver 22 and the second circumferential driver 24 are both connected with the control module 3, and the control module 3 can control the first circumferential driver 22 and the second circumferential driver 24 to work according to the received instruction so as to cut off or communicate the fresh air filtering passage, the fresh air direct blowing passage or the air exhaust passage, so that the blowing mechanism 2 is in different working states.
In this embodiment, the instruction received by the control module 3 may be sent by a user controlling an operation panel or a remote controller, or may be sent by an environment monitoring module (not shown in the figure) connected to the control module 3; environmental monitoring module is integrated in new fan, can carry out real-time supervision to indoor outer environmental status and send corresponding instruction to control module 3 according to the monitoring result.
For example, the environment monitoring module can monitor indoor and outdoor temperature and humidity, and various gas components (including oxygen, carbon dioxide, carbon monoxide, formaldehyde, ammonia gas, hydrogen, methane, flue gas, and the like) in the air or the concentration of dust in real time, and if the indoor temperature and humidity or the concentration of oxygen are monitored to be too low, an instruction is sent to the control module 3, and the control module 3 opens the fresh air filtering passage to enable the blowing mechanism 2 to be in a fresh air introducing position (or opens the fresh air direct blowing passage to enable the blowing mechanism 2 to be in a fresh air direct blowing position); if the concentration of harmful gases such as indoor carbon dioxide and the like is overhigh, the temperature and humidity are overhigh or the dust is too much, an instruction is sent to the control module 3, the control module 3 opens the air exhaust passage to enable the blowing mechanism 2 to be in the waste air exhaust position (or opens the fresh air direct blowing passage to enable the blowing mechanism 2 to be in the fresh air direct blowing position).
A micro-heating module (not shown) may be further disposed on the fresh air filtering path to heat the fresh air introduced into the room. The micro-heating module is also connected with the control module 3, and when the indoor temperature is too low, the control module 3 starts the micro-heating module when fresh air is introduced.
In order to ensure that the first blocking member 27 or the second blocking member 28 is in sealing contact with the outer edge of the opening of the outdoor air inlet/outlet 512, the outer edge of the outdoor air inlet/outlet 512 is surrounded by a sealing baffle 56, the first blocking member 27 in the fresh air introducing position is in sealing contact with the sealing baffle 56 to block the outdoor air inlet/outlet 512, and the second blocking member 28 in the waste air discharging position is in sealing contact with the sealing baffle 56 at the outer edge of the opening of the first air passing opening 282 to prevent air leakage.
As shown in fig. 15, 20 and 21, and as can be seen from fig. 14, in the present embodiment, in order to increase the intake air volume, the circumferential width of the air suction opening 211a is large, and extends almost to the entire left cover 211; and the circumferential width of the blowing port 212a is relatively small to intensively blow air.
In this embodiment, the air supply opening 212a is located between the left housing 211 and the right housing 212, and the distance between the air supply opening 211a and the air suction opening 211a is relatively small, so that the wind wheel 23 cannot directly introduce air from the air suction opening 211a to the air supply opening 212a at a short distance, and an air guide channel 212b needs to be additionally arranged, so that the air suction opening 211a is only arranged on one side of the air supply opening 212a, and a space is reserved for the air guide channel 212 b.
In this embodiment, the wind guide channel 212b starts from the wind suction port 211a, bypasses the right housing 212 on the opposite side of the wind wheel 23 from the wind suction port 211a, and then reaches the wind supply port 212 a; under the centrifugal action of the wind wheel 23, the airflow is accelerated through the wind guide channel 212b and then leaves the wind direction regulating cover 21 from the air supply outlet 212 a.
Meanwhile, an air guide 214 between the air suction port 211a and the air supply port 212a is convexly arranged on the inner peripheral wall of the left housing 211, the front end of the air guide 214 extends to the wind wheel 23 to form a partition between the air suction port 211a and the air supply port 212a, and a wind shielding surface 214a facing the air suction port 211a and a first air guiding surface 214b facing the air supply port 212a are formed on the air guide 214; the wind shielding surface 214a can prevent the airflow from flowing from the air suction port 211a to the air supply port 212a directly, and guide the airflow to the wind wheel 23; the first air guiding surface 214b serves to guide the air flow in the air guiding passage 212b into the air outlet 212 a.
In this embodiment, the first wind guiding surface 214b is arc-shaped and smoothly connected to the wind guiding channel 212 b; correspondingly, the air guide grille 283 is arranged at the first air passing opening 282 of the second blocking piece 28, the air guide grille 283 is also provided with a second air guide surface 283a which is arc-shaped like the first air guide surface 214b, and the windward end of the second air guide surface 283a extends towards the air supply opening 212a so as to face the air flow from the air guide channel 212 b.
As shown in fig. 20, at least two second air guiding surfaces 283a are formed on the air guiding grill 283, which are located at different circumferential positions of the first air passing opening 282 (at the axial position of the first air passing opening 282, the number of the second air guiding surfaces 283a is not limited, and may be two or a multiple of two, depending on the grill density), so as to disperse and send the air flow from the entire circumferential positions of the air passing opening 212a and the first air passing opening 282, and avoid the air flow from concentrating on the side where the first air guiding surface 214b is located.
The air suction inlet 211a is only arranged on the left housing 211, but the fresh air filtering inlets 511 are arranged on two sides of the outdoor air inlet 512 in pairs; when the first blocking member 27 in the fresh air introducing position blocks the outdoor air inlet/outlet 512, in order to facilitate the supply of air to the air suction opening 211a through the fresh air filtering inlet 511 on the other side of the outdoor air inlet/outlet 512, the outdoor air inlet/outlet 512 of this embodiment is not as high as the radial air supply gap, but an air passage is reserved at two ends of the outdoor air inlet/outlet 512.
As shown in fig. 15, which is combined with fig. 20, 21 and 15, the filter member 29 is also detachably mounted at the air suction port 211a, and the filter member 29 can not only assist the first filter member 53 in filtering fresh air when fresh air is introduced, but also filter indoor waste air when waste air is exhausted; the kind of the filter member 29 can be arbitrarily selected.
As shown in fig. 15, in the present embodiment, the filter member 29 is mounted on the left housing 211 in the following manner: the outer periphery of the left housing 211 is provided with a mounting groove 211b matched with the filter element 29, and the width and length of the mounting groove 211b are both larger than that of the air suction opening 211a, so that the opening outer edge of the air suction opening 211a supports the filter element 29; meanwhile, the outer peripheral side of the left cover 211 is provided with a limit frame 211c for limiting the filter element 29 in the mounting groove 211b, and the width of the limit frame 211c is smaller than that of the mounting groove 211b to form a filter element mounting opening 211d.
As can be seen from fig. 21, when the fresh air blower is in the waste air discharge position, the second filter mounting port 211d is exposed at the indoor air inlet/outlet 111, and the second filter 29 can be easily mounted or dismounted in the room.
The working principle of the new fan of this embodiment is:
when the air blowing mechanism is used, the power supply is started, the environment monitoring module monitors indoor and outdoor environment parameters in real time and sends monitoring results to the control module 3, the control module 3 compares indoor numerical values and outdoor numerical values of the same environment parameters, and automatically generates corresponding instructions according to the comparison results to control the air blowing mechanism 2 to work;
if it is monitored that the indoor numerical value of one or more environmental parameters is too low, such as too low oxygen concentration, too low temperature and humidity, the control module 3 starts the first circumferential driver 22, the first circumferential driver 22 drives the wind direction regulating and controlling housing 21 to rotate to enable the first blocking piece 27 to block the outdoor wind inlet/outlet 512, and at this time, the second blocking piece 28 is in sealing contact with the outer edge of the opening of the second wind inlet/outlet 172 at the outer edge of the opening of the first wind inlet/outlet 282; the control module 3 drives the second circumferential driver 24 at the same time, the second circumferential driver 24 drives the wind wheel 23 to rotate in the forward direction, under the attraction of the wind wheel 23, the fresh air filtering inlet 511, the air suction inlet 211a, the wind guide channel 212b, the air supply outlet 212a, the first air passing inlet 282, the second air passing inlet 172 and the indoor air inlet and outlet 111 are sequentially communicated to form a fresh air filtering passage, and outdoor fresh air enters the room after being filtered by the first filter element 53 and the filter element 29 on the fresh air filtering passage to adjust the indoor oxygen concentration or the indoor temperature and humidity; when the indoor temperature is low and needs to be raised, the control module 3 simultaneously starts the micro-heating module to heat the fresh air flowing through the fresh air filtering passage and then enters the room, at the moment, the indoor air inlet/outlet 111 serves as a fresh air outlet, and the air direction regulating housing 21 is located at the fresh air introducing position;
if it is monitored that the indoor numerical value of one or more environmental parameters, such as carbon dioxide, carbon monoxide, formaldehyde, smoke, etc., is too high, the fresh air can be introduced to dilute the indoor air in the above manner, but it is preferable to switch the fresh air machine to the exhaust mode to exhaust the indoor waste air as soon as possible, that is, the control module 3 sends a control instruction to the first circumferential driver 22, the first circumferential driver 22 drives the wind direction regulating housing 21 to rotate to make the wind supply outlet 212a align with the outdoor wind inlet/outlet 512, at this time, the second blocking piece 28 is in sealing contact with the outer edge of the opening of the outdoor wind inlet/outlet 512 at the outer edge of the opening of the first wind passing outlet 282, and the first blocking piece 27 is directly opposite to the indoor wind inlet/outlet 111, but since the circumferential width of the first blocking piece 27 is smaller than the circumferential width of the indoor wind inlet/outlet 111, the first blocking piece 27 cannot block the indoor wind inlet/outlet 111; the control module 3 drives the second circumferential driver 24 at the same time, so that the second circumferential driver 24 drives the wind wheel 23 to rotate reversely, under the suction of the wind wheel 23, the indoor air inlet/outlet 111, the second air passing outlet 172, the air suction inlet 211a, the wind guide channel 212b, the air supply outlet 212a, the first air passing outlet 282 and the outdoor air inlet/outlet 512 are communicated to form an air exhaust passage, indoor waste air is filtered by the filter element 29 at the air suction inlet 211a and then is exhausted to the outdoor through the air exhaust passage, at this time, the indoor air inlet/outlet 111 is used as an air exhaust inlet, the outdoor air inlet/outlet 512 is used as an outdoor air inlet/outlet, and the wind direction regulating housing 21 is in a waste air exhaust position;
besides adopting the fresh air introducing position to introduce outdoor fresh air and adopting the waste air discharging position to discharge indoor waste air, under the relatively emergent condition, the wind direction regulating and controlling housing 21 can be positioned at a fresh air direct blowing position so as to rapidly blow in fresh air to the indoor space to accelerate air circulation; at this time, the control module 3 sends a control instruction to the first circumferential driver 22, the first circumferential driver 22 drives the wind direction regulating housing 21 to rotate to enable the first blocking piece 27 to unblock (completely unblock or partially unblock) the outdoor wind inlet/outlet 512 and the air passing port 212a to still expose (partially expose or completely expose) at the indoor wind inlet/outlet 111, the control module 3 simultaneously drives the second circumferential driver 24 to enable the second circumferential driver 24 to drive the wind wheel 23 to rotate in the forward direction, under the suction of the wind wheel 23, the outdoor wind inlet/outlet 512, the air suction port 211a, the air guide channel 212b, the air supply port 212a, the first air passing port 282, the second air passing port 172 and the indoor wind inlet/outlet 111 are sequentially communicated to form a fresh wind direct blowing passage, at this time, the outdoor wind inlet/outlet 512 is used as a fresh wind direct blowing inlet, the indoor wind inlet/outlet 111 is used as a fresh wind direct blowing inlet, and at this time, the wind direction regulating housing 21 is located at a fresh wind direct blowing position;
