In addition, when describing pipelines or channels, the "connected" and "connected" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0060] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0061] Negative ions are negatively charged oxygen molecules that can combine with particulate matter such as dust, pollen, and bacteria in the air, causing them to settle to the ground, thereby purifying the air. Negative ions can also neutralize positive charges in the air, reducing the impact of static electricity on the human body and equipment.

[0062] The function of the air conditioner negative ion generator is to improve the air quality by releasing negative ions. Therefore, the air conditioner negative ion generator can improve the indoor air quality, reduce the spread of bacteria, viruses and harmful particles, improve the air freshness, and benefit people's health and comfort.

[0063] The air purification devices in the related art are mostly used in cabinet air conditioners, see Figure 1 . The negative ion return air purification device 1 of the air conditioner includes an outer frame structure 2 and a high-voltage power supply module 3, a micro-electrostatic purification module 4 and an electrostatic dust removal module 5 installed in the outer frame structure 2. The electrostatic dust removal module 5 is connected to the negative high-voltage contact of the high-voltage power supply module 3 to ionize the air to produce a large number of air negative ions. The pollutants in the air combine with the negative ions and then flow through the micro-electrostatic purification module 4 connected to the positive high-voltage contact of the high-voltage power supply module 3. The pollutants are collected by the micro-electrostatic purification module 4, which can further achieve efficient purification treatment of pollutants such as PM2.5, and can also sterilize and degrade volatile harmful gases.

[0064] The above-mentioned negative ion return air purification device 1 can purify pollutants, but since the negative ions generated by the electrostatic dust removal module 5 ionizing the air will be adsorbed when passing through the micro-electrostatic purification module 4, the content of negative ions in the air entering the room is relatively low.

[0065] Based on the above problems, a combined air conditioner 100 is provided in an embodiment of the present application. The combined air conditioner 100 is an air treatment device assembled from various air treatment functional sections, and is an important component of the central air conditioning system. The functional sections of the combined air conditioner 100 generally include a primary new return air section, a surface cooling water retaining section, a heating section, a humidification section, a secondary return air section, a fan section, a silencer section, a medium efficiency filtration section, a sterilization and purification section, and a heat recovery section. The combined air conditioner 100 is generally composed of more than three functional sections, and different air treatment requirements are achieved through the combination of different functional sections.

[0066] See also Figure 2 In the embodiment of the present application, a combined air conditioner 100 is provided, which includes a purification section 10, a fan section 20 and an air outlet section 30. The purification section 10, the fan section 20 and the air outlet section 30 are sequentially connected along the air flow direction F1 and are interconnected. The treated air can enter the room through the purification section 10, the fan section 20 and the air outlet section 30 in sequence.

[0067] The fan section 20 includes a fan 21, and the fan 21 is used to introduce the treated air from the fan section 20 into the air outlet section 30. The air outlet section 30 is used to discharge the treated air into the room through the air outlet 80.

[0068] For example, see Figure 2 The fan section 20 also includes a motor 22, which is connected to the fan 21 and is used to drive the fan 21 to operate so that the fan 21 can work normally. The outlet of the fan 21 is also provided with a flow equalizing plate 23, which can make the air flowing out of the fan 21 more uniform.

[0069] For example, see Figure 3 In the embodiment of the present application, the combined air conditioner 100 further includes a mixed air filter section 40. The mixed air filter section 40, the purification section 10, the fan section 20 and the air outlet section 30 are sequentially connected along the air flow direction F1 and are interconnected. The mixed air filter section 40 includes a primary filter 41, which can filter dust particles larger than 5 microns in the air.

[0070] The mixed air filter section 40 is connected to the return air outlet 60 and the fresh air outlet 70. The indoor air entering from the return air outlet 60 and the outdoor air entering from the fresh air outlet 70 are mixed and enter the mixed air filter section 40 for filtration. The filtered air then enters the purification section 10 for purification, is introduced into the outlet section 30 through the fan section 20, and then enters the room through the outlet 80.

[0071] For example, see Figure 4In the embodiment of the present application, the combined air conditioner 100 further includes a surface cooling section 50. The surface cooling section 50, the purification section 10, the fan section 20 and the air outlet section 30 are sequentially connected along the air flow direction F1 and are interconnected. The surface cooling section 50 includes a heat exchanger 51 and a water receiving tray 52. ​​The heat exchanger 51 can cool down or heat up the air entering the combined air conditioner 100 to adjust the temperature of the air. The heat exchanger 51 is installed in the surface cooling section 50. The water receiving tray 52 is installed on the base of the surface cooling section 50 to collect the water vapor condensed on the heat exchanger 51.

[0072] The indoor air entering from the return air outlet 60 and the outdoor air entering from the fresh air outlet 70 are mixed and enter the surface cooling section 50 to adjust the temperature. The temperature-adjusted air then enters the purification section 10 for purification, is introduced into the air outlet section 30 through the fan section 20, and then enters the room through the air outlet 80.

[0073] For example, see Figure 5 In the embodiment of the present application, the combined air conditioner 100 further includes a mixed air filter section 40 and a surface cooling section 50. The mixed air filter section 40, the surface cooling section 50, the purification section 10, the fan section 20 and the air outlet section 30 are sequentially connected along the air flow direction F1 and are interconnected. The mixed air filter section 40 includes a primary filter 41, and the surface cooling section 50 includes a heat exchanger 51 and a water receiving tray 52.

[0074] The indoor air entering through the return air outlet 60 and the outdoor air entering through the fresh air outlet 70 are mixed and enter the mixed air filter section 40 and the surface cooling section 50 for filtering and temperature adjustment, and then enter the purification section 10 for purification. After being introduced into the air outlet section 30 through the fan section 20, the air enters the room through the air outlet 80.

[0075] See also Figure 6 Combined with Figure 2 The purification section 10 includes an installation cavity and a purification device 11 located in the installation cavity, and the purification device 11 is connected to the inner wall of the installation cavity. In this way, the treated air flows into the fan section 20 through the purification device 11, so that the treated air can be purified. The purification device 11 includes a purification module 12, and the purification module 12 is used to purify the treated air, so that the air flowing through the purification section 10 is fully purified.

[0076] The purification module 12 includes a first ionization unit 121 and an adsorption unit 122. The first ionization unit 121 is located on a side of the adsorption unit 122 away from the fan section 20. In this way, the air entering the purification module 12 first passes through the first ionization unit 121 and then passes through the adsorption unit 122.

[0077] The air entering the purification module 12 is ionized by the first ionization unit 121 to generate negative ions, and some dust in the air adsorbs the negative ions and carries negative charges. When the air is ionized by the first ionization unit and flows through the adsorption unit 122, the dust carrying negative charges is adsorbed on the adsorption unit 122.

[0078] Continue to see Figure 2 The combined air conditioner 100 further includes a second ionization unit 123, which is disposed in the purification section 10 and is used to ionize the air flowing through the adsorption unit 122 to obtain negative ions. The air flowing through the adsorption unit 122 is ionized for the second time when passing through the second ionization unit 123. Since the dust in the air that is easy to adsorb negative ions has been adsorbed by the adsorption unit 122, more negative ions can be ionized when the air flows through the second ionization unit. Therefore, the efficiency of the purification module in generating negative ions is improved, thereby improving the efficiency of air purification.

[0079] Therefore, the combined air conditioner 100 provided in the embodiment of the present application can improve the efficiency of generating negative ions in the purification section 10, thereby improving the efficiency of air purification.

[0080] In some embodiments, see Figure 7 The second ionization unit 123 is disposed in the purification module 12. The second ionization unit 123 is located on a side of the adsorption unit 122 close to the fan section 20. The second ionization unit 123 is used to ionize the air flowing through the adsorption unit 122 to obtain negative ions.

[0081] It is understandable that by disposing the second ionization unit 123 in the purification module 12 , the space utilization rate of the purification section 10 can be improved, thereby reducing the volume of the combined air conditioner 100 .

[0082] In some embodiments, see Figure 8 The purification device 11 includes a plurality of purification modules 12, and the purification modules 12 are used to purify the treated air. The combined air conditioner 100 is adapted by combining the plurality of purification modules 12. Each purification module 12 is connected to an adjacent purification module 12, so that the purification area can be increased, so that the air flowing through the purification section 10 can be fully purified.

[0083] It is understandable that the purification device 11 can be easily replaced and repaired by combining multiple purification modules 12. If a single purification module 12 is damaged, only the damaged module needs to be replaced, thereby reducing maintenance costs.

[0084] In addition, the standardized production of the purification module 12 can also improve production efficiency. When the combined air conditioner 100 is used in different scenarios, the number and shape of the purification module 12 can be adaptively selected for different models of the combined air conditioner 100, thereby reducing the design cost and production cost of the purification device 11.

[0085] Continue to see Figure 8 The purification module 12 further includes a first edge 124 and a second edge 125 . In two adjacent purification modules 12 , the first edge 124 of one purification module 12 is connected to the second edge 125 of the other purification module 12 .

[0086] In this way, the number and arrangement and connection method of the purification modules 12 can be adjusted according to different combined air conditioners 100.

[0087] Exemplarily, a circular hole 126 is formed on the first edge 124 and the second edge 125 , and the first edge 124 and the second edge 125 of two adjacent purification modules 12 can be connected by screws or bolts.

[0088] In some embodiments, see Fig. 9 Combined with Figure 7 The purification module 12 includes: an electric control assembly 127, a first power transmission electrode sheet 1271 and a second power transmission electrode sheet 1272. In order to enable the first power transmission electrode sheet 1271 and the second power transmission electrode sheet 1272 to be energized, the first power transmission electrode sheet 1271 and the second power transmission electrode sheet 1272 are connected to the electric control assembly 127, and the electrical properties of the first power transmission electrode sheet 1271 and the second power transmission electrode sheet 1272 are opposite. In order to enable the second ionization unit 123 to ionize molecules in the air, the second ionization unit 123 is connected to the electric control assembly 127.

[0089] The first power transmission electrode sheet 1271 is connected to the electric control assembly 127 and is used to supply power to the first ionization unit 121. The second power transmission electrode sheet 1272 is connected to the electric control assembly 127 and is used to supply power to the adsorption unit 122.

[0090] Pollutants such as dust in the air are more likely to combine with negative ions. In order to remove dust in the air, the first ionization unit 121 and the adsorption unit 122 have opposite electrical properties, and the first ionization unit 121 is negatively charged and the adsorption unit 122 is positively charged.

[0091] In this way, the first ionization unit 121 ionizes the air entering the purification module 12, and the negatively charged dust and other pollutants flowing through the first ionization unit 121 are adsorbed and filtered when entering the positively charged adsorption unit 122, thereby achieving the first purification of the air. The second ionization unit 123 has the same electrical properties as the first ionization unit 121 and is also negatively charged. The air flowing out of the adsorption unit 122 is ionized for the second time in the second ionization unit 123. Since pollutants such as dust that are easy to bind to negative ions have been removed, the efficiency of generating negative ions by the second ionization is higher, thereby increasing the negative ion content in the room.

[0092] It is understandable that an indicator light may also be provided on the electric control assembly 127 to display the operating status of the purification module 12 .

[0093] In some embodiments, see Fig. 9 Combined with Figure 7 The first power transmission electrode sheet 1271 and the second power transmission electrode sheet 1272 are located on the same side of the electric control assembly 127 . Thus, the first ionization unit 121 and the adsorption unit 122 are also located on the same side of the electric control assembly 127 .

[0094] It can be understood that in order to achieve a better purification effect, the first ionization unit 121, the adsorption unit 122 and the second ionization unit 123 are located on the same side of the electronic control assembly 127, and in order to be able to be connected to the electronic control assembly 127 for power supply, they are located on the side where the first power transmission electrode sheet 1271 is located.

[0095] The purification module 12 further includes a first powered electrode sheet 1211, which is located on the side of the first ionization unit 121 facing the electric control assembly 127. In this way, through the abutment between the first powered electrode sheet 1211 and the first power transmission electrode sheet 1271, the electric control assembly 127 supplies power to the first ionization unit 121, thereby achieving primary ionization of the air.

[0096] On this basis, see Fig. 9 Combined with Figure 7 The purification module 12 further includes a second powered electrode sheet 1221 , which is located on a side of the adsorption unit 122 facing the electric control assembly 127 .

[0097] In this way, through the contact between the second powered electrode sheet 1221 and the second power transmission electrode sheet 1272, the second power transmission electrode sheet 1272 supplies power to the second powered electrode sheet 1221, and the electric control assembly 127 supplies power to the adsorption unit 122, and the electrical property is opposite to that of the first ionization unit 121. Therefore, the adsorption unit 122 is positively charged. The dust in the air after passing through the first ionization unit 121 is negatively charged, and the positively charged adsorption unit 122 can adsorb and collect the negatively charged dust.

[0098] In some embodiments, see Fig. 9 The second ionization unit 123 includes: a support rod 1231 and an ionization unit 1232. The support rod 1231 is connected to the electric control assembly 127 and to the ionization unit 1232. It can be understood that the support rod 1231 is connected between the electric control assembly 127 and the ionization unit 1232, and the power of the electric control assembly 127 can be transmitted to the ionization unit 1232, and the ionization unit 1232 performs secondary ionization on the air.

[0099] In order to achieve higher ionization efficiency and higher content of negative ions generated by ionization, the ionization unit 1232 includes a discharge needle 1233 for discharging.

[0100] It should be noted that the discharge phenomenon that occurs at the sharp part of an object under the action of a strong electric field is called tip discharge. When the charge of the conductor and the surrounding environment are the same, the sharper the tip of the conductor, the more obvious the tip effect. This is because the sharper the tip, the greater the curvature, the higher the surface charge density, and the stronger the field strength near it.

[0101] In some embodiments, see Fig.10 and Fig.11 The ion unit 1232 includes a protective plate 1236, and the protective plate 1236 forms a receiving space 1234. The discharge needle 1233 is located in the receiving space 1234. The receiving space 1234 can provide protection for the discharge needle 1233 to prevent the discharge needle 1233 from being hit during transportation or installation. In addition, during installation, the discharge needle 1233 is not easy to accidentally injure the staff, which can ensure the safety of the staff.

[0102] One of the two opposite sides of the accommodation space 1234 in the air circulation direction F1 is a closed wall surface, and the other side is provided with a discharge port 1235, and the discharge port 1235 is connected to the installation cavity. The discharge needle 1233 includes a root and a tip. The root of the discharge needle 1233 is connected to the closed wall surface of the accommodation space 1234, and the tip of the discharge needle 1233 faces the discharge port 1235. The tip of the discharge needle 1233 can discharge to the installation cavity through the discharge port 1235. In this way, the air passing through the adsorption unit 122 can be ionized by the tip of the discharge needle 1233 at the discharge port 1235.

[0103] Exemplarily, the accommodating space 1234 may be provided with at least one communication port penetrating the protective plate 1236 in a direction perpendicular to the air circulation direction F1. The communication port is connected to the installation cavity, and the discharge needle 1233 may enter and exit the installation cavity through the communication port, which facilitates the installation of the discharge needle 1233. In addition, the air in the installation cavity may enter and exit the installation cavity through the communication port, and may be ionized by the discharge needle 1233 near the installation cavity, thereby improving the ionization efficiency of the second ionization unit 123.

[0104] Exemplarily, the protective plate 1236 may also be provided in two pieces, the two protective plates 1236 are connected to the support rod 1231 along a direction perpendicular to the air flow direction F1, and a receiving space 1234 is formed between the two protective plates 1236, and the discharge needle 1233 is located in the receiving space.

[0105] Exemplarily, the accommodating space 1234 may also be semicircular.

[0106] In some embodiments, see Fig.12 The purification module 12 includes a shell 128, which has a purification chamber 1281 and a first mounting hole 1282 and a second mounting hole 1283 connected to the purification chamber 1281. The first mounting hole 1282 and the second mounting hole 1283 are arranged opposite to each other along the air circulation direction F1. Compared with the first mounting hole 1282, the second mounting hole 1283 is closer to the fan section 20. In this way, there is enough space in the shell 128 to install the first ionization unit 121, the adsorption unit 122 and the second ionization unit 123. The first ionization unit 121, the adsorption unit 122 and the second ionization unit 123 are sequentially installed in the purification chamber 1281 of the shell 128 along the air circulation direction F1, and the second ionization unit 123 is located at the second mounting hole 1283.

[0107] In this way, when the air entering the purification module 12 is ionized by the first ionization unit 121 and then flows through the adsorption unit 122, the dust with negative charge is adsorbed on the adsorption unit 122. The air passing through the adsorption unit 122 is ionized again when it flows through the second ionization unit 123. The dust in the air that is easy to adsorb negative ions has been adsorbed by the adsorption unit 122, and more negative ions can be ionized when the air flows through the second ionization unit 123. In this way, the purification module 12 can complete the primary ionization-adsorption-secondary ionization of the air to achieve purification of the air.

[0108] It can be understood that, in order to simplify the structure, the housing 128 includes a first wall plate 1284, a second wall plate 1285, a third wall plate 1286 and an electric control assembly 127, and the electric control assembly 127 is also a part of the housing 128. The electric control assembly 127, the first wall plate 1284, the second wall plate 1285 and the third wall plate 1286 are sequentially connected around the first ionization unit 121 and enclose the purification chamber 1281. The first wall plate 1284 is arranged opposite to the electric control assembly 127.

[0109] In some embodiments, see Fig.12 The purification device 11 further includes a filter 24, which is disposed at the first mounting hole 1282 and can simply filter the air entering the purification module 12. The filter 24 is detachably connected to the housing 128, so that the filter 24 can be regularly disassembled, replaced or cleaned, which is beneficial to improving air quality.

[0110] Exemplarily, the filter screen 24 is detachably connected to the housing 128 via a rotatable stopper 241. Fig.13 At this time, the limiter 241 is in the locked position, and the limiter 241 limits the position of the filter 24, so that the filter 24 is connected to the housing 128. When the limiter 241 rotates to the edge of the electric control assembly 127, the lock on the filter 24 can be released, and the filter 24 can be disassembled for cleaning and replacement.

[0111] In some other embodiments, the filter 24 may also be detachably connected to the housing 128 by screws or bolts, and when replacing or cleaning the filter 24, the filter 24 can be removed by simply removing the screws or bolts.

[0112] In some embodiments, see Fig.14 In order to limit the filter 24, a first limiting portion 1273 is provided on the side of the electric control assembly 127 facing the first ionization unit 121, and a limiting surface 1274 is provided on the side of the first limiting portion 1273 close to the filter 24. The limiting surface 1274 abuts against the filter 24, so as to limit the position of the filter 24.

[0113] In order to cooperate with the first position limiting portion 1273 to limit the position of the filter 24, a first flange 1289 bent toward the electric control assembly 127 is provided on the edge of one side of the first wall plate 1284 away from the second mounting hole 1283, and the filter 24 is connected to the side of the first flange close to the second mounting hole 1283. The first flange 1289 cooperates with the first position limiting portion 1273 to limit the position of the filter 24.

[0114] In order to limit the positions of the first ionization unit 121 and the adsorption unit 122, a second limiting portion 1287 and a third limiting portion 1288 are provided on the side of the first wall plate 1284 facing the purification chamber 1281. The second limiting portion 1287 is used to limit the position of the first ionization unit 121, and the third limiting portion 1288 is used to limit the position of the adsorption unit 122.
