[0019] The disclosure of this invention will become more readily understood with reference to the accompanying drawings. It will be readily understood by those skilled in the art that these drawings are for illustrative purposes only and are not intended to limit the scope of protection of this invention. Furthermore, similar numbers in the drawings are used to denote similar components, wherein:

[0020] Figure 1 This is a rear view of a fan coil unit according to an embodiment of the present invention;

[0021] Figure 2 This is a rear view including the fan coil unit of the ion generating device according to an embodiment of the present invention;

[0022] Figure 3 This is a perspective view of an ion generating apparatus according to an embodiment of the present invention; and

[0023] Figure 4This is a side view of an ion generating apparatus according to an embodiment of the present invention. Detailed Implementation

[0024] Figure 1 This is a rear view of the fan coil unit according to an embodiment, specifically a view viewed from the inside of the partition 3 of the fan coil unit. The fan coil unit according to the embodiment may include a motor 1 located in the center, which is mounted, for example, on the partition 3. The output shafts 11, 12 of the motor 1 can be connected to fans (not shown) located on either side of the motor in fan housings 21, 22, thereby driving the fans in the housings 21, 22 to rotate, delivering air out of the plane defined by the partition 3 and into the room. The housings 21, 22 may be, for example, centrifugal fan housings, cross-flow fan housings, or housings of other types of fans. Although the illustration shows two housings 21, 22 on either side of the motor 1 and the fans therein, in other embodiments, it should be understood that only one housing and fan on one side of the motor 1 may be present. In addition to the conventional return air inlet, the fan coil unit according to the embodiment of the invention also has a plurality of holes 31 formed on the partition 3, for example, above the motor 1 or at other suitable locations. Because the air in the area corresponding to the multiple holes 31 on the inner side of the partition 3 can be partially drawn away by the fan, a negative pressure will be formed in this area, and some air will be drawn into the room outside the partition 3. Figure 2 As shown, according to an embodiment of the present invention, the ion generating device 4 can be installed aligned with the plurality of holes 31, thereby allowing the ion generating device 4 to add plasma, positive and negative ions, and negative ions into the return air passing through the plurality of holes 31. A portion of the return air can be drawn by a fan and thus added to the indoor air circulation, while another portion returns to the room through other channels, such as returning to the room through the plurality of holes 31. As described herein, plasma, negative ions, and positive and negative ions can purify the air, remove odors, and / or sterilize. It should be understood that although the ion generating devices according to various embodiments are described herein in conjunction with air circulation systems, particularly fan coil units of air conditioning systems, in alternative embodiments, the ion generating devices according to the embodiments can be applied to other air circulation systems, such as fresh air systems, air purifiers, etc.

[0025] Continue to refer to Figure 3 and Figure 4An ion generating apparatus according to an embodiment of the present invention is described, comprising: a power module 100; a negative electrode plate 5 connected to the power module 100; the negative electrode plate 5 having a first side 51 and a second side 52, and a ground plane 6 spaced apart from the first side 51 of the negative electrode plate 5, the first side 51 of the negative electrode plate 5 including a plurality of plasma needles 53 extending toward the ground plane 6, the plurality of plasma needles 53 not in contact with the ground plane 6 (spaced apart); a positive electrode plate 7 spaced apart from the second side 52 of the negative electrode plate 5, the positive electrode plate 7 being connected to the power module 100 and having an polarity opposite to that of the negative electrode plate 5, and a plurality of carbon fiber brushes 54, 74 arranged on opposite sides of the negative electrode plate 5 and the positive electrode plate 7, the carbon fiber brushes 54 being arranged in corresponding positions. In some embodiments, the plurality of carbon fiber brushes 54 on the negative electrode plate 5 may be provided with a negative high voltage by the power module 100, and the plurality of carbon fiber brushes 74 on the positive electrode plate 7 may be provided with a positive high voltage by the power module 100. Negative electrode 5 and positive electrode 7 can be printed circuit boards with copper wires to conduct power supply voltage to the carbon fiber brush and plasma needle locations. Power module 100 can be connected to a conventional power supply, such as a 220V power supply, and convert it to a high voltage to be applied to positive electrode 7 and negative electrode 5. To generate both negative and positive ions, negative electrode 5 can have a voltage greater than that of positive electrode 7, for example, the voltage of negative electrode 5 is between 1.5 and 2.5 times that of positive electrode 7. In some embodiments, positive electrode 7 can have a voltage of +5 kV and negative electrode 5 can have a voltage of -10 kV, i.e., the voltage of negative electrode 5 is twice the voltage of positive electrode 7. In this case, both negative and positive ions are formed between positive electrode 7 and negative electrode 5. The ion generating device based on embodiments of the present invention can simultaneously generate positive and negative ions, negative ions, and plasma. Furthermore, in the ion generating device based on the embodiments of the present invention, the plasma generating device and the positive and negative ion generating devices share the same negative electrode plate 5, which improves the integration of the device, making the device particularly compact and able to be installed in the narrow space on the back side of the partition plate 3.

[0026] In some embodiments, such as Figure 4 As shown more clearly in the diagram, the ground plane 6, negative electrode 5, and positive electrode 7 can be arranged parallel to each other. In some embodiments, the distance between the negative electrode 5 and the ground plane 6 is comparable to the distance between the negative electrode 5 and the positive electrode 7, for example, both distances are 40 mm, or for example, the distance between the negative electrode 5 and the ground plane 6 and the distance between the negative electrode 5 and the positive electrode 7 are both in the range of 30 mm to 50 mm. In some embodiments, the ion generating device 4 further includes a first mounting bracket 8 and a second mounting bracket 9 connected to the two ends of the ground plane 6, the negative electrode 5, and the positive electrode 7, and the power module 100 can be disposed in the first mounting bracket 8 or the second mounting bracket 9. For example, as shown in the diagram... Figure 4As shown, in this embodiment, the power module 100 is disposed in the second mounting bracket 9 and enclosed by the housing of the second mounting bracket 9. In some embodiments, the first mounting bracket 8 and the second mounting bracket 9 have mounting holes 81, 91 to facilitate fixing them to the partition plate 3 by bolts.

[0027] In some embodiments, the carbon fiber brushes 54, 74 of the negative electrode plate 5 and the positive electrode plate 7 are held together in a bundle by carbon fiber brush protective covers 55, 75, which can be attached to the negative electrode plate 5 and the positive electrode plate 7. As shown in the figure, the carbon fiber brushes 54, 74 on the negative electrode plate 5 and the positive electrode plate 7 are spaced at an appropriate distance, thereby forming negative ions and positive and negative ions therebetween. Figure 3 As shown more clearly in the diagram, the ground plane 6 may be provided with openings 61 corresponding to the positions of the plurality of plasma needles 53, thereby generating plasma. The ground plane 6 may be made of stainless steel, such as S50C.

[0028] In some embodiments, the plurality of plasma needles 53 on the first side 51 of the negative electrode plate 5 and the plurality of carbon fiber brushes 54 on the second side 52 of the negative electrode plate 5 are positioned correspondingly. Since the negative electrode plate 5 is a printed circuit board, arranging the plasma needles 53 and carbon fiber brushes 54 on both sides of it in a corresponding position simplifies the design and manufacturing of the printed circuit board. In some embodiments, the plurality of plasma needles 53 on the first side 51 of the negative electrode plate 5 and / or the plurality of carbon fiber brushes 54 on the second side 52 of the negative electrode plate 5 are arranged uniformly at equal intervals to generate more uniform plasma, negative ions, and positive and negative ions.

[0029] According to some aspects, the present invention also aims to protect a fan coil unit including an ion generating device according to various embodiments. The fan coil unit includes a partition 3 with a plurality of holes 31. A motor 1 is disposed on the back side of the partition 3. A volute 21, 22 is arranged on at least one or both sides of the motor 1. A fan is located in at least one volute and driven by the motor 1 via motor shafts 11, 12. The ion generating device 4 is disposed on the back side of the partition 3 aligned with the plurality of holes 31, thereby adding generated ions to the return airflow passing through the holes.

[0030] According to some aspects, the present invention also aims to protect an air conditioning system comprising a fan coil unit according to various embodiments.

[0031] The specific embodiments described above are merely for the purpose of more clearly illustrating the principles of the present invention, wherein the various components are clearly shown or described to make the principles of the present invention easier to understand. Various modifications or variations can be readily made to the present invention by those skilled in the art without departing from the scope of the invention.
