With continued reference to fig. 1-3, in some embodiments, the fresh air machine further comprises: a heat exchanger 8 and a third fan 9;
the heat exchanger 8 is provided with a first air inlet, a first air outlet, a second air inlet and a second air outlet;
the shell 1 is also provided with a second indoor air inlet 14 and an outdoor air outlet 15;
specifically, the first air inlet is communicated with the outdoor air inlet 11 and the first indoor air inlet 13 through the first air duct 101;
the first air outlet is communicated with the air inlet of the electronic filter 2;

In the embodiment of the present invention, the outdoor air flows in from the outdoor air inlet 11, passes through the heat exchanger 8, and enters the electronic filter 2, and meanwhile, the outdoor air flows in from the second indoor air inlet 14, passes through the heat exchanger 8, enters the fourth air duct 104, and flows out from the outdoor air outlet 15. In this way, in the indoor/outdoor air exchange scenario, the air flowing from the outdoor into the indoor exchanges heat with the air flowing from the indoor into the outdoor in the heat exchanger 8, and the temperature of the air entering the indoor is made appropriate.
The heat exchanger 8 may be an existing heat exchanger, and it can be understood that two air flows for heat exchange in the heat exchanger respectively flow in different channels, that is, in the heat exchange process, only heat is exchanged between the air flows of different air paths without air mixing, thereby preventing mutual pollution of indoor air and outdoor air.
Further, as shown in fig. 1, the first air inlet and the second air outlet of the heat exchanger 8 may be provided with a filter screen 81 for filtering the air.
The heat exchanger 8 is used in an indoor/outdoor air exchange scenario in which the first damper 110 is opened and the second damper 130 is closed.

Referring to fig. 4a and 4b, there is shown a structure of an ionizer 22, the ionizer 22 including: a hollow electrode column 221, a ground electrode column 222, a support structure 223, a first electrode strip 224 and a second electrode strip 225;
the ground electrode column 222 is fixed at the central axis position of the hollow electrode column 221 through a support structure 223;
the first electrode strips 224 are distributed on the outer wall of the hollow electrode column 221, and the second electrode strips 225 are distributed on the inner wall of the hollow electrode column 221;
the first electrode strip 224 comprises a plurality of first tip electrodes 2241 directed to the outside of the hollow electrode column 221, and the second electrode strip 225 comprises a plurality of second tip electrodes 2251 directed to the inside of the hollow electrode column 221;
the high voltage generator 3 is electrically connected with the hollow electrode column 221;
wherein, after the air flows into the air cleaner, power is supplied to the hollow electrode column, the first tip electrode 2241 is discharged to purify the air flowing through the outer wall of the hollow electrode column 221, and the second tip electrode 2251 is discharged to purify the air flowing through the inner wall of the hollow electrode column 221.
The material of the first tip electrode 2241 and the second tip electrode 2251 is a material having good conductivity, for example: copper, aluminum, nickel, etc., when the hollow electrode column 221 is energized, the first and second tip electrodes 2241 and 2251 can discharge, thereby generating negative ions, plasma, ozone, etc., to purify the air.
The ground electrode column 222 functions to generate a large voltage difference between the second tip electrode 2251 and the ground electrode column 222, thereby performing a discharge. It can be understood that, in a practical application scenario, when the ionizer is installed inside the air purifier, a grounded cylinder electrode is disposed outside the ionizer, so that a large voltage difference is generated between first tip electrode 2241 and the cylinder electrode, thereby achieving discharge.
As shown in fig. 4a, the supporting structure 223 is a cross-shaped supporting frame, the number of the supporting structures 223 can be 2, and the supporting structures 223 are respectively arranged at the upper end and the lower end of the hollow electrode column 221 to fixedly connect the electrode column 222; the number of the supporting structures 223 may also be 3 or more, and the supporting structures are respectively disposed at the upper and lower ends and the middle portion of the hollow electrode column 221 to ensure that the ground electrode column 222 is fixed and stable.
It should be noted that the material of the supporting structure 223 should be non-conductive material to avoid short circuit between the ground electrode column 222 and the hollow electrode column 221.
In the embodiment of the present invention, when air flows through the ionizer 22, it simultaneously flows through the outer and inner walls of the hollow electrode column 221, and power is supplied to the hollow electrode column 221, so that the first and second tip electrodes 2241 and 2251 discharge to simultaneously purify the air flowing through the outer and inner walls of the hollow electrode column 221. Because all set up the pointed end electrode at hollow electrode post 221 outer wall and inner wall and discharged the purification, can make the air purification efficiency of the ion purifier of unit length promote to original about 2 times, promoted ion generator's air purification efficiency under the unit size greatly, like this under the condition that purification efficiency satisfies the demand, can reduce ion generator's size, and then reduce air purifier's overall dimension, avoid air purifier to occupy more interior space.
In some embodiments, the first electrode strips 224 are distributed on the outer wall of the hollow electrode column 221 along a spiral direction, and the second electrode strips 225 are distributed on the inner wall of the hollow electrode column 221 along a spiral direction;
the first electrode belt 224 is spiraled in the same direction as the second electrode belt 225.
Furthermore, the connecting line of the adjacent first tip electrode 2241 is a spiral line, and a first inclination angle is formed between the connecting line and the horizontal plane; the line connecting adjacent second tip electrodes 2251 is a spiral line and has a second inclination angle with respect to the horizontal plane.
It can be understood that the electrode strips are distributed on the hollow electrode column 221 along the spiral direction, so that the tip electrodes only need to be arranged along the electrode strips to realize that the connecting line of the adjacent tip electrodes is a spiral line. When air flows through the tip electrode, the air is guided according to the spiral arrangement of the tip electrode, so that the air flows on the outer wall and the inner wall of the hollow electrode column 221 in a vortex mode, turbulence formed by mutual disturbance of the air is reduced, and wind noise of the air purifier is reduced; simultaneously, the vortex air current flows stably and is favorable to the purification to the air, further improves air purifier's air purification efficiency.
Specifically, the first inclination angle is any angle from 3 ° to 45 °, and the second inclination angle is any angle from 3 ° to 45 °, so that the air purifier can obtain a good wind noise reduction effect and air purification efficiency. It is understood that the first and second tilt angles may be the same and may be different.
It should be noted that when the spiral direction of the electrode strips is set, the environmental factors applied to the air purifier are considered, specifically, the local turning force direction is considered, and the turning force influences the swirling flow of the fluid, so that when the gas is guided, the guiding direction needs to be matched with the turning force direction.
Specifically, when the use area of the air purifier is northern hemisphere, along the gas flow direction, the spiral direction of the electrode belt is counterclockwise; when the use area of the air purifier is the southern hemisphere, the spiral direction of the electrode belt is clockwise along the gas flowing direction. Therefore, the influence of the deflection force on the flow of the air flow can be avoided, and the smooth flow of the air is ensured.
Referring to fig. 5a to 5e, there is shown a structure of an ionizer 22 including: hollow electrode column 31, ground electrode column 32, support structure 33;
the hollow electrode column 31 is formed by curling a parallelogram-shaped conductive plate;
the ground electrode column 32 is fixed at the middle shaft position of the hollow electrode column 31 through a supporting structure 33;
a plurality of electrode areas 310 which are parallel to each other are arranged on the side wall of the hollow electrode column 31;
the electrode area 310 includes a plurality of first tip electrodes 311 and a plurality of second tip electrodes 312 integrally formed with the hollow electrode column 31;
the first tip electrode 311 bends towards the outer wall of the hollow electrode column 31, and the second tip electrode 312 bends towards the inner wall of the hollow electrode column 31;
the high voltage generator 3 is electrically connected with the hollow electrode column 31;
after the air flows into the air purifier, power is supplied to the hollow electrode column, so that the first tip electrode 311 discharges to purify the air flowing through the outer wall of the hollow electrode column, and the second tip electrode 312 discharges to purify the air flowing through the inner wall of the hollow electrode column.
The hollow electrode column 31 is formed by winding a conductive plate made of a material having good conductivity, such as: copper, aluminum, nickel, and the like, since the first tip electrode 311 and the second tip electrode 312 are integrally formed with the hollow electrode column 31, the first tip electrode 311 and the second tip electrode 312 are also materials having good electrical conductivity, and when the hollow electrode column 31 is energized, the first tip electrode 311 and the second tip electrode 312 can discharge electricity, thereby generating negative ions, plasma, ozone, and/or other substances to purify the air.
The ground electrode column 32 functions to generate a large voltage difference between the second tip electrode 312 and the ground electrode column 32, thereby performing a discharge. It can be understood that, in a practical application scenario, when the ionizer is installed inside the air purifier, a grounded cylinder electrode is disposed outside the ionizer, so that a large voltage difference is generated between the first tip electrode 311 and the cylinder electrode, thereby achieving discharging.
As shown in fig. 5a, the supporting structure 33 is a cross-shaped supporting frame, the number of the supporting structures 33 can be 2, and the supporting structures 33 are respectively arranged at the upper end and the lower end of the hollow electrode column 31 to fixedly connect the electrode column 32; it should be noted that the material of the supporting structure 33 should be non-conductive material to avoid short circuit between the ground electrode column 32 and the hollow electrode column 31.
In the embodiment of the present invention, when passing through the ionizer, it simultaneously passes through the outer wall and the inner wall of the hollow electrode column 31, and at this time, power is supplied to the hollow electrode column 31, so that the first tip electrode 311 and the second tip electrode 312 are discharged to simultaneously purify the air passing through the outer wall and the inner wall of the hollow electrode column 31. Because all set up sharp-end electrode at hollow electrode post 31 outer wall and inner wall and discharged and purify, can make the air purification efficiency of the ion purifier of unit length promote to original about 2 times, promoted ion generator's air purification efficiency under the unit size greatly, like this under the condition that purification efficiency satisfies the demand, can reduce ion generator's size, and then reduce air purifier's overall dimension, avoid air purifier to occupy more interior space.
In the embodiment of the invention, the ion generator adopts the hollow electrode column, and the hollow electrode column is provided with the first tip electrode and the second tip electrode which are integrally formed with the hollow electrode column, wherein the first tip electrode is bent towards the outer wall of the hollow electrode column, and the second tip electrode is bent towards the inner wall of the hollow electrode column, so that the air flowing through the outer wall and the inner wall of the hollow electrode column is purified by discharging through the first tip electrode and the second tip electrode, the air purification efficiency of the ion generator under the unit size is improved, and the size and the purification effect of the ion generator can be considered.
In fig. 5b to 5d, when the hollow electrode shaft 31 is machined, a plurality of electrode regions 310 parallel to each other are first defined on the conductive plate, and the electrode regions 310 shown in fig. 5b are rectangular. After the electrode area 310 is determined, a first tip electrode 311 and a second tip electrode 312 are machined in the determined electrode area 310.
Referring to fig. 5c, the conductive plate is cut in the electrode area 310, thereby forming tip electrodes alternately opposing in the electrode area 310.
It should be noted that the cutting shapes of the first tip electrode 311 and the second tip electrode 312 shown in fig. 5c are only schematic, and in the actual processing process, a person skilled in the art can adjust the cutting shapes according to the actual product requirements.
After the cutting of the first tip electrode 311 and the second tip electrode 312 is completed, the first tip electrode 311 is bent toward the outer wall of the conductive plate (the outer wall refers to the outer wall after the conductive plate is curled into the hollow electrode post 31), and the second tip electrode 312 is bent toward the inner wall of the conductive plate (the inner wall refers to the inner wall after the conductive plate is curled into the hollow electrode post 31). As shown in fig. 5d, for the single electrode region 310, the first tip electrode 311 and the second tip electrode 312 are respectively directed to both sides of the conductive plate from a top view.
After the bending of all the first and second tip electrodes 311 and 312 is completed, the conductive plate is curled, thereby obtaining the hollow electrode column 31.
It is understood that, as shown in fig. 5e, there is a joint 313 formed by connecting two ends of the conductive plate on the side of the curled hollow electrode column 31, and the joint 113 may be fixed by a bolt or by welding, and the fixing manner of the joint 113 is not particularly limited in the embodiment of the present invention.
In some embodiments, the electrode region 310 is inclined from the horizontal plane.
In the embodiment of the present invention, since the electrode area 310 has an inclined angle with the horizontal plane, the first tip electrode 311 and the second tip electrode 312 processed in the electrode area 310 also have an inclined angle with the horizontal plane, and the tip electrodes with the inclined angles can generate a flow guiding effect on air in addition to discharging and purifying air. Thus, when air flows through the outer wall and the inner wall of the hollow electrode column 31, the air is guided by the first tip electrode 311 and the second tip electrode 312, so that the air flows in a vortex mode on the outer wall and the inner wall of the hollow electrode column 31, turbulence formed by mutual disturbance of the air is reduced, and wind noise of the air purifier is reduced; simultaneously, the vortex air current flows stably and is favorable to the purification to the air, further improves air purifier's air purification efficiency.
Further, the inclination angle may be any angle of 3 ° to 45 °. Referring to fig. 5b and 5e, after the conductive plate is curled, the lower side of each electrode region 110 can be connected with the upper side of the next electrode region 310 by using a proper inclination angle, so that the sidewall of the curled hollow electrode column 31 forms a spiral winding structure to guide the air flowing through, thereby forming a vortex air flow.
It should be noted that when the inclination direction of the electrode region 310 is set, an environmental factor applied to the air purifier is considered, specifically, the environmental factor is a local turning force direction, and the turning force affects the swirling flow of the fluid, so that when the gas is guided, the guiding direction needs to be matched with the turning force direction.
Specifically, when the use area of the air purifier is northern hemisphere, along the gas flowing direction, the sidewall of the curled hollow electrode column 31 should form a spiral winding structure with the spiral direction being counterclockwise; when the air purifier is used in the southern hemisphere, the sidewall of the curled hollow electrode column 31 should form a spiral winding structure with a clockwise spiral direction along the air flowing direction. Therefore, the influence of the deflection force on the flow of the air flow can be avoided, and the smooth flow of the air is ensured.
In some embodiments, in the ionizer shown in fig. 4a and 4b described above or the ionizer shown in fig. 5a to 5e described above, the tip shapes of the first tip electrode and the second tip electrode are both triangular, and the apex angle is not more than 45 °.
The tip electrode with the parameter range can obtain better discharge effect and improve the efficiency of air purification.
Referring to fig. 6a and 6b, fig. 6a is an electric field profile of the tip electrode and fig. 6b is an energy profile of the tip electrode. As can be seen from fig. 6a, in any tip model, the electric field is concentrated on the surface of the conductor and is significantly concentrated at the tip than at other positions. The electric field intensity of the arc tip model (i.e. the model on the right side in fig. 4 a) at the tip is larger than that of the triangle tip model (i.e. the model on the left side in fig. 6 a), but the electric field of the triangle tip model is more concentrated at the tip, and it can be seen from fig. 4b that the energy is concentrated and distributed only near the tip of the conductor, and the energy of the arc tip model (i.e. the model on the right side in fig. 6 b) at the tip is larger than that of the triangle tip model (i.e. the model on the left side in fig. 6 b), but the range of the triangle tip model is wider.
Therefore, the sharper the position on the surface of the conductor, the higher the charge density of the tip of the conductor, the stronger the field intensity nearby, and the concentrated energy distribution near the tip.
