In addition, because the positive ions and the negative ions can reach the indoor space along with the high-speed airflow and do not need to enter the air conditioner, the contact between the positive ions and the negative ions and metal parts in the air conditioner can be reduced, the attenuation and loss of the positive ions and the negative ions are reduced, and the reliable sterilization effect is ensured. Specifically, the specific position of the air outlet area is related to the setting position and the air outlet direction of the fan 600 of the air conditioner, and the air outlet area can be determined through numerical simulation and experimental tests for the designed air conditioner and the fan 600 thereof. Specifically, the discharge electrode 200 is a carbon brush type discharge electrode.

Specifically, the number of the discharge electrodes 200 is at least one, and when the number of the discharge electrodes 200 is at least two, the at least two groups of the discharge electrodes 200 are spaced along the profile of the air outlet 100.

Specifically, the air conditioner is a ducted air conditioner, and has the advantages of good hiding performance, low manufacturing cost and convenience in use and maintenance. As shown in fig. 6, the space in the casing 400 is divided into an air inlet side and an air outlet side by the partition 402, the blower 600 is located on the air inlet side, the heat exchanger 700 can be disposed in the air outlet side, and the airflow blown out from the blower 600 firstly passes through the heat exchanger 700 for heat exchange and then is blown out from the air outlet 100, that is, the discharge electrode 200 can be located on the air outlet side of the casing 400 and located downstream of the heat exchanger 700. In addition, the ducted air conditioner can be arranged with a blast pipe at the air outlet 100 of the casing 400, and also can be arranged with an air inlet pipe at the air inlet 404 of the casing 400, and the final air supply position and air inlet position can be changed by specifically configuring the blast pipe and the blast pipe, and the blast pipe can be specifically communicated with the indoor space to realize indoor air return and outdoor space communication, so as to introduce outdoor fresh air, realize flexible air supply scheme and air inlet scheme, and improve the air inlet and outlet flexibility of the air conditioner. Of course, the ducted air conditioner can be provided with only the blast pipe, only the air inlet pipe, or both the blast pipe and the air inlet pipe. When an air inlet duct is provided, the ion generating module 800 may be specifically disposed at the air inlet 404 of the housing 400, rather than at an end of the air inlet duct remote from the air inlet 404, to shorten the routing path.

Example two:

as shown in fig. 6, on the basis of the first embodiment, the second embodiment provides an air conditioner, which further includes a fan 600, the fan 600 is located in the casing 400, and the discharge electrode 200 is disposed toward the air outlet direction of the fan 600.

In this embodiment, it is further defined that the air conditioner further includes a blower 600 located within the case 400. By making the discharge electrode 200 face the air outlet direction of the fan 600, that is, in the width direction of the air outlet 100, the air outlet area is defined as the area corresponding to the fan outlet 602 of the fan 600, so that the high-speed airflow blown out from the fan 600 can directly act on the discharge electrode 200, which is helpful for blowing a large amount of positive ions and negative ions, and further can bring a large amount of positive ions and negative ions into the room by using the high-speed airflow, thereby further killing bacteria and viruses in the indoor air and improving the air quality. For example, as shown in fig. 6, in the width direction of the outlet 100, a G region corresponding to the fan 600 is an outlet region.

Specifically, as shown in fig. 6, the blower 600 has a blower outlet 602, in the width direction of the air outlet 100, the distance between the central point of the blower outlet 602 and the discharge electrode 200 is a first distance d1, the distance between two points where the blower outlet 602 is farthest away is a second distance d2, and the ratio of the first distance d1 to the second distance d2 is 1/3 or less. For the fan 600, the wind speed is greatest at the center point of the fan outlet 602, and the closer the center point of the fan outlet 602 is, the greater the wind speed. The distance between two points (i.e. the second distance d2) farthest from the fan outlet 602 represents the width of the fan outlet 602, and the discharge electrode 200 is arranged in the range where the distance between the discharge electrode 200 and the center point of the fan outlet 602 is less than or equal to 1/3 of the width of the fan outlet 602, that is, the air outlet area is defined as the middle 2/3 section of the fan outlet 602, so that the air speed in the air outlet area is higher than that in other areas, and the air speed is sufficiently high, which is beneficial to blowing a large amount of positive ions and negative ions in a centralized manner, and further, a large amount of positive ions and negative ions can be brought into a room by using high-speed airflow, so that bacteria and viruses in indoor air can be further killed, and the air quality is improved.

Example three:

as shown in fig. 2, based on the first embodiment or the second embodiment, the third embodiment provides an air conditioner, further comprising a heat exchanger 700, wherein the heat exchanger 700 is located in the casing 400, and the discharge electrode 200 is located between the heat exchanger 700 and the casing 400.

In this embodiment, a heat exchanger 700 is further disposed in the casing 400 to exchange heat with the air flow passing through the heat exchanger 700, so as to adjust the temperature of the air flow, and thus adjust the temperature of the indoor space. In the height direction of the air outlet 100, because a narrow airflow channel is defined between the heat exchanger 700 and the housing 400 at the air outlet 100, the airflow flowing through the narrow airflow channel has a large wind speed, and by arranging the discharge electrode 100 at the narrow airflow channel, that is, in the height direction of the air outlet 100, the air outlet area is defined as the area between the heat exchanger 700 and the housing 400, the high-speed airflow flowing between the heat exchanger 700 and the housing 400 can directly act on the discharge electrode 200, which is helpful for blowing a large amount of positive ions and negative ions, and further can bring a large amount of positive ions and negative ions into the room by using the high-speed airflow, so that bacteria and viruses in the indoor air can be further killed, and the air quality can be improved. Specifically, two regions may be formed between the heat exchanger 700 and the housing 400 in the height direction of the air outlet 100, and the discharge electrode 200 may be located in any one of the two regions, for example, may be located in a region toward which the fan outlet 602 faces, that is, the discharge electrode 200 is disposed toward the air outlet direction of the fan 600, for example, as shown in fig. 2, in the height direction of the air outlet 100, a region B on the lower side of the air outlet 100 toward which the fan 600 faces is an air outlet region. Of course, the discharge electrodes 200 may be located in both regions (the number of the discharge electrodes 200 is at least two groups).

Specifically, as shown in fig. 7, a set of discharge electrodes 200 may be disposed at the air outlet 100 corresponding to the blower 600, or as shown in fig. 8, when the air outlet 100 has a large width, two sets of discharge electrodes 200 are symmetrically disposed at the air outlet 100 along the width direction, so as to improve the contact chance between bacteria and viruses in the air flow and the discharge electrodes 200, which is helpful for improving the sterilization effect. Further, whether one, two or more sets of discharge electrodes 200 are provided, as referred to above, at least part of the discharge electrodes 200 may be provided in the air outlet area below the air outlet 100.

In some embodiments, the number of the fans 600 is at least two, and at least one set of the discharge electrodes 200 is correspondingly disposed on each fan 600.

In this embodiment, by providing at least two fans 600 and arranging all fans 600 coaxially, the air supply width of the air outlet 100 can be increased, and it is ensured that each position along the air supply width direction has a large airflow velocity, which is helpful to ensure the uniformity of air supply. At this time, at least one set of discharge electrodes 200 is correspondingly configured for each fan 600, so that the high-speed airflow blown by each fan 600 can be matched with the discharge electrodes 200, that is, the airflow blown out along each part of the air supply width can be affected by positive ions and negative ions, thereby being beneficial to fully killing bacteria and viruses in the airflow flowing out through the air outlet 100 and improving the air supply cleanliness. And positive ions and negative ions released by the discharge electrodes 200 can enter the room along with high-speed airflow, so that the quantity of the positive ions and the negative ions entering the room can be increased, bacteria and viruses in the indoor air can be killed, and the indoor air quality is improved.

Specifically, as shown in fig. 10, three fans 600 are arranged in parallel, as shown in fig. 9, a set of discharge electrodes 200 may be arranged in the air outlet area on the lower side of the air outlet 100 at the position corresponding to the air outlet direction of each fan 600, and a set of discharge electrodes 200 may be further added in the air outlet area on the upper side of the air outlet 100, that is, two sets of discharge electrodes 200 are symmetrically arranged along the height direction, so as to increase the contact chance between bacteria and viruses in the supply air flow and the discharge electrodes 200, which is helpful for improving the sterilization effect.

Example four:

on the basis of any of the above embodiments, the fourth embodiment provides an air conditioner, and the distance between the discharge electrode 200 and the metal part of the air conditioner is greater than or equal to 15 mm.

In this embodiment, the positive ions and the negative ions released from the discharge electrode 200 encounter the metal member, and are absorbed by the metal member to be attenuated and lost. By keeping the distance between the discharge electrode 200 and the metal member of the air conditioner at 15mm or more and further at 16mm or more, the degree of attenuation of positive ions and negative ions can be reduced, thereby ensuring a sufficient sterilization effect.

In this embodiment, the discharge electrode 200 includes a positive electrode 202 and a negative electrode 204, which are used in a pair, and on which a high voltage is loaded, and which are capable of releasing positive ions and negative ions. The distance E between the positive electrode 202 and the negative electrode 204 is larger than or equal to 15mm, so that the possibility of loss caused by direct neutralization of just-emitted positive ions and negative ions can be reduced, the distance E between the positive electrode 202 and the negative electrode 204 is smaller than or equal to 32mm, a sufficient discharge effect can be ensured, a large amount of positive ions and negative ions can be released, and both the positive ions and the negative ions are helpful for ensuring sufficient positive and negative ion generation amount, so that a reliable sterilization effect is realized, and the sterilization efficiency is improved. Further, the distance E between the positive electrode 202 and the negative electrode 204 is equal to or greater than 16mm and equal to or less than 30 mm.

It is understood that since the mounting bracket 300 is used to fixedly connect the discharge electrode 200, the mounting bracket 300 is also provided at the air outlet 100. Specifically, the number of the mounting brackets 300 is identical to the number of the discharge electrodes 200 and is arranged in a one-to-one correspondence, i.e., one mounting bracket 300 connects one set of the discharge electrodes 200.

As shown in fig. 3, the mounting bracket 300 is provided with a diversion surface 302, and the diversion surface 302 extends from the air outlet 100 to the inside of the housing 400 and inclines towards the water pan 500.

In this embodiment, when the air conditioner operates in the cooling mode, condensed water is easily generated since the temperature of the air flow is low. The installation support 300 is provided with the flow guide surface 302 extending towards the inside of the shell 400, the flow guide surface 302 is inclined towards the water receiving tray 500 in the shell 400 while extending, condensed water formed on the installation support 300 can be guided to flow along the flow guide surface 302 under the action of gravity, meanwhile, the installation support 300 is provided with the water leakage port 304 facing the water receiving tray 500, the water leakage port 304 is specifically positioned at one end of the flow guide surface 302 extending into the inside of the shell 400, the condensed water flowing along the flow guide surface 302 can flow into the water receiving tray 500 through the water leakage port 304, the discharge of the condensed water is realized, the condensed water collection on the installation support 300 is favorably reduced, the reliable operation of the discharge electrode 200 is ensured, and the reliable sterilization effect is ensured.
