Description

Technical Field

[0002] As people's demands for quality of life continue to improve, related technologies have introduced air conditioners that are equipped with ion generators to generate ions. The airflow blown into the room by the air conditioner contains ions, which can purify and sterilize the indoor air to improve the user experience. However, the ion generators in related technologies are often located at the air outlet, and the air outlet is often equipped with an air guide component to adjust the airflow direction at the air outlet. Ions are easily adsorbed by the air guide component, making it difficult for the ions to diffuse into the indoor air, which in turn leads to a decrease in the sterilization and purification effects of the ions in the air. Therefore, this problem needs to be solved. Utility Model Content

[0045] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0046] Reference below Figures 1-10 An air conditioner according to an embodiment of the present invention is described.

[0047] Reference Figure 2-Figure 4 According to an embodiment of the present invention, the air conditioner includes a housing assembly 20, an air duct assembly 40, a heat exchanger assembly 30, and an ion generator 50. The housing assembly 20 is formed with an air inlet 21 and an air outlet 22. The air duct assembly 40 is arranged in the housing assembly 20 and includes an air duct volute 41 and a fan assembly 44. The air duct volute 41 has an air duct 414. The fan assembly 44 is installed in the air duct volute 41. The fan assembly 44 has a wind wheel 441. Located in the air duct 414, the heat exchanger assembly 30 is disposed in the housing assembly 20 and is located between the air duct assembly 40 and the air inlet 21. The ion generator 50 is disposed in the housing assembly 20 and is mounted on the air duct volute 41. The ion generator 50 includes an electrically connected high-voltage transformer 51 and an ion emitter 52. The ion emitter 52 is located downstream of the wind wheel 441 and is mounted on the side wall of the air duct 414. When the air conditioner is operating, the wind wheel 441 drives air into the housing assembly 20 through the air inlet 21 and flows toward the heat exchanger assembly 30. After heat exchange in the heat exchanger assembly 30, the air flows toward the air duct 414. The air in the air duct 414 is blown into the room through the air outlet 22 to increase or decrease the temperature of the room.

[0048] The high-voltage coil 51 is electrically connected to the ion emitter 52, and the high-voltage coil 51 provides the required high voltage electricity to the ion emitter 52, thereby ensuring that the ion emitter 52 can generate ions, such as BE ions. The ion generator 50 is installed in the air duct volute 41, which can support and fix the ion generator 50. The ion emitter 52 is installed on the side wall of the air duct 414, so that the BE ions ejected by the ion emitter 52 can be blown directly into the air duct 414, so that these BE ions can follow the air flow in the air duct 414 and then be blown into the room through the air outlet 22. For example, the presence of BE ions in the air flow can enable the air conditioner to purify the air and remove bacteria, viruses, dust and other small particles in the air, which helps to improve the user experience.

[0049] For example, an air guide component for adjusting the direction of airflow is provided at the air outlet 22. The air guide component may be an air guide plate or a louver mechanism, and the BE ions move downward under the action of their own gravity. If the ion emitter 52 is provided at the air outlet 22, the BE ions ejected by the ion emitter 52 will be directly adsorbed by the air guide component at the air outlet 22 to a greater extent, resulting in too few BE ions blown out into the room from the air outlet 22, resulting in poor effect of BE ion sterilization and air purification of the air conditioner.

[0050] The ion generating device 50 is installed on the air duct volute 41 and the ion emitter 52 is located on the downstream side of the wind wheel 441. In this way, the distance between the ion emitter 52 and the air outlet 22 can be extended. When the air flow flows in the air duct 414, within this longer distance, the BE ions follow the air flow, and the injection direction of the BE ions can be changed. For example, the nozzle of the ion emitter 52 is facing downward, causing the injection direction of the BE ions to face downward, and the wind wheel 441 drives the air flow to flow forward from back to front. The forward-flowing air flow can change the movement direction of the BE ions so that the BE ions flow forward as much as possible, instead of directly diffusing downward, so that when the BE ions flow through the air outlet 22, the flow direction of the BE ions is closer to the horizontal direction. This can reduce the adsorption amount of BE ions by the air guide component at the air outlet 22, thereby effectively increasing the amount of BE ions blown into the room, so that more BE ions can diffuse into the indoor air, and thus can enhance the effect of the air conditioner BE ions on sterilizing and purifying the indoor environment.

[0051] For example, a rotatable wind guide plate is provided at the air outlet 22, and a wind dispersion hole is formed on the wind guide plate that penetrates the wind guide plate along the thickness direction of the wind guide plate. When the wind guide plate is in a closed position, the ion generating device 50 is installed on the air duct volute 41 and the ion emitter 52 is located on the downstream side of the wind wheel 441. In this way, the distance between the ion emitter 52 and the air outlet 22 can be extended. When the air flow flows in the air duct 414, within this longer distance, for example, BE ions move downward due to their own gravity. The forward-flowing air flow can change the movement direction of the BE ions so that the BE ions flow forward as much as possible. When the BE ions flow through the air outlet 22, the flow direction of the BE ions is closer to the thickness direction of the wind guide plate. This can effectively reduce the adsorption amount of the wind guide plate and the BE ions, so that more BE ions can flow out from the wind dispersion hole, thereby achieving better air purification and sterilization effects.

[0052] According to the air conditioner of the embodiment of the present invention, the ion generating device 50 is installed on the air duct volute 41, and the ion emitting element 52 is located on the downstream side of the wind wheel 441, which can extend the distance between the ion emitting element 52 and the air outlet 22. Within this longer distance, the air flow is driven by the wind wheel 441 to flow forward from back to front. The forward-flowing air flow can change the direction of ion movement so that the ions flow forward as much as possible. This can reduce the amount of ion adsorption by the air guide component at the air outlet 22, thereby effectively increasing the amount of ions blown into the room, which is beneficial to enhancing the effect of the ions blown out by the air conditioner on sterilizing the indoor environment and purifying the air.

[0053] Reference Figure 3-Figure 5 According to some embodiments of the present invention, the air duct 414 has a first side wall 415 and a second side wall 416 that are opposite to each other along the width direction, and the ion emitter 52 is installed on the first side wall 415. By installing the ion emitter 52 on the first side wall 415 on one side of the air duct 414 along the width direction, the blocking area of ​​the ion emitter 52 on the flow cross-section of the air duct 414 can be reduced, thereby reducing or avoiding the increase in the flow resistance of the airflow in the air duct 414 due to the ion emitter 52 blocking the flow cross-section of the air duct 414 being too large.

[0054] Reference Figure 3 、 Figure 5 and Figure 6 According to some embodiments of the present invention, the ion emitter 52 is snap-connected to the first side wall 415, so that the installation method of the ion emitter 52 on the first side wall 415 is simple and has strong stability, and the maintenance or replacement of the ion emitter 52 is more convenient.

[0055] Reference Figure 4-Figure 6According to some embodiments of the present invention, the ion emitter 52 includes an ion emitter head 521, which faces the second side wall 416. The ion emitter 52 is installed on the first side wall 415 on one side of the air duct 414 along the width direction, and the ion emitter head 521 faces the second side wall 416 on the other side of the air duct 414 along the width direction. The ejected ions can move toward the other side of the air duct 414 along the width direction, so that the ions cover the flow cross-section of the air duct 414 as much as possible, thereby making the ions more fully contact with the airflow in the air duct 414, and the initial position and direction of the ions ejected by the ion emitter head 521 can maintain a certain distance from the first side wall 415, which can reduce the adsorption loss of ions by the first side wall 415 to a certain extent.

[0056] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the rotation axis of the wind wheel 441 and the air duct volute 41 both extend in the vertical direction, and the ion emitter 52 is disposed in the vertical direction. The rotation axis of the wind wheel 441 extends in the vertical direction, and the wind wheel 441 rotates about the rotation axis. The air duct volute 41 also extends in the vertical direction. When the wind wheel 441 is in operation, the rotation of the wind wheel 441 can drive airflow to flow smoothly in the air duct 414. By arranging the ion emitter 52 in the up-down direction so that the rotation axis of the ion emitter 52 and the wind wheel 441 and the extension direction of the air duct volute 41 are the same, the adsorption loss of ions by the wind wheel 441 can be reduced. For example, the ion emitter 52 is installed on the first side wall 415 and is arranged in the horizontal direction, which may cause the distance between the ion emitter 52 and the wind wheel 441 to be too small. The distance between the ion emitter 52 and the wind wheel 441 is too small, resulting in the ions being adsorbed by the wind wheel 441. By arranging the ion emitter 52 in the up-down direction, it can be ensured that the ion emitter 52 maintains a certain distance from the upstream wind wheel 441, thereby reducing the adsorption loss of ions by the wind wheel 441.

[0057] Reference Figure 4 、 Figure 6 and Figure 10 According to some embodiments of the present invention, the ion emitting element 52 includes a plurality of ion emitting heads 521 arranged in the up and down directions. The plurality of ion emitting heads 521 can increase the amount of ions ejected, thereby increasing the amount of ions blown into the room, thereby improving the sterilization and purification effect of the air conditioner on the indoor air.

[0058] In the description of the present invention, “plurality” means two or more.

[0059] Reference Figure 4 、 Figure 6 and Figure 10According to some embodiments of the present invention, the ion emitter 52 includes two ion emitter heads 521, which are located at the upper and lower ends of the ion emitter 52, respectively. By providing two ion emitter heads 521 at the upper and lower ends of the ion emitter 52, the coverage of the ions can be effectively increased, thereby increasing the amount of ions diffused into the indoor air through the air outlet 22. Furthermore, the two emitter heads can also improve the reliability of the ion emitter 52. If one emitter head malfunctions, the other emitter head can still normally eject ions, and the air conditioner can still achieve the effect of purifying and sterilizing the indoor air.

[0060] Reference Figure 3 、 Figure 8 and Figure 9 According to some embodiments of the present invention, a mounting opening 417 is formed on the first side wall 415, and the ion emitter 52 is mounted in the mounting opening 417. The ion emitter 52 includes an ion emitter head 521, and the ion emitter head 521 faces the air duct 414. The mounting opening 417 facilitates the installation of the ion emitter 52 on the first side wall 415. The mounting opening 417 penetrates the first side wall 415. When the ion emitter 52 is installed in the mounting opening 417, the ion emitter head 521 can be directed toward the air duct 414, so that the ejected ions flow directly into the air duct 414, and the electrical connection between the ion emitter 52 and the high-voltage package 51 is facilitated.

[0061] Reference Figure 3 、 Figure 5 and Figure 9 According to some embodiments of the present invention, the ion emitting element 52 includes an ion emitting frame 522, which is mounted on the mounting opening 417. The ion emitting frame 522 includes an ion emitting seat 523 and an ion emitting cover 524. The ion emitting cover 524 is connected to the side of the ion emitting seat 523 facing the air duct 414. The ion emitting cover 524 and the ion emitting seat 523 together define an emitting chamber. The ion emitting head 521 is mounted on the ion emitting seat 523 and is located in the emitting chamber. At least a portion of the ion emitting cover 524 is located in the air duct 414. The ion emitting cover 524 has a plurality of through holes 525 formed therein, which connect the emitting chamber with the air duct 414. The ion emitting head 521 faces the through holes 525. The ion emitting cover 524 being at least partially located in the air duct 414 may include the following situations: for example, a portion of the ion emitting cover 524 may be located in the air duct 414; or another example, another portion of the ion emitting cover 524 may be located in the air duct 414.

[0062] The ion emission base 523 secures and supports the ion emission head 521 and the ion emission cover 524. The ion emission cover 524 protects the ion emission head 521 within the emission chamber, reducing or preventing damage to the ion emission head 521 from external impacts. The emission chamber is connected to the air duct 414 via a through hole 525, and the ion emission head 521 faces the through hole 525, ensuring that the ions ejected by the ion emission head 521 flow smoothly into the air duct 414.

[0063] Optionally, the ion emission frame 522 is provided with a first limit buckle 527, and the first limit buckle 527 cooperates with the installation port 417. Through the cooperation of the first limit buckle 527 and the installation port 417, the ion emission frame 522 and the first side wall 415 can be snapped together, so that the connection method between the ion emission frame 522 and the first side wall 415 is simple and has strong stability, and it is convenient to install or remove the ion emission frame 522 on the first side wall 415, and through the cooperation of the first limit buckle 527 and the installation port 417, the assembly position of the ion emission frame 522 on the first side wall 415 can be ensured to be accurate.

[0064] Among them, there can be multiple first limit buckles 527, for example, the first limit buckles 527 can be provided at both ends of the ion emission frame 522 in the up and down directions, and the ion emission component 52 is arranged in the up and down directions, so as to further enhance the stability of the connection between the ion emission frame 522 and the first side wall 415.

[0065] Optionally, a second limiting buckle 528 is provided on the ion emission cover 524, and a mounting hole is provided on the ion emission seat 523. The second limiting buckle 528 cooperates with the mounting hole. By cooperating with the second limiting buckle 528 and the mounting hole, a snap-on connection between the ion emission cover 524 and the ion emission seat 523 can be achieved, so that the connection method between the ion emission cover 524 and the ion emission seat 523 is simple and has strong stability, and is convenient for the installation or disassembly between the ion emission cover 524 and the ion emission seat 523. By cooperating with the second limiting buckle 528 and the mounting hole, the assembly position between the ion emission cover 524 and the ion emission seat 523 can be ensured to be accurate.

[0066] Among them, there can be multiple second limit buckles 528, and the second limit buckles 528 can be multiple and arranged at circumferential intervals along the ion emission cover 524. The number of mounting holes is the same as the number of second limit buckles 528 and corresponds one to one, which can further enhance the connection stability between the ion emission cover 524 and the ion emission seat 523.

[0067] Reference Figure 5 、 Figure 6 and Figure 10According to some embodiments of the present invention, the rotation axis of the wind wheel 441 and the air duct volute 41 both extend in the vertical direction. The ion emitting element 52 is disposed in the vertical direction and includes multiple ion emitting heads 521 arranged in the vertical direction. The multiple ion emitting heads 521 are respectively directed toward through-holes 525 at different positions. While the ion emitting cover 524 protects the multiple ion emitting heads 521, the multiple ion emitting heads 521 are directed toward through-holes 525 at different positions. This ensures that the ions ejected by the multiple ion emitting heads 521 can all flow smoothly into the air duct 414 through the through-holes 525 at corresponding positions, thereby effectively increasing the coverage of the ions and thereby increasing the amount of ions diffused into the indoor air through the air outlet 22.

[0068] Reference Figure 6 and Figure 10 According to some embodiments of the present invention, the ion emitter 52 includes a discharge tip 526, which is disposed on the ion emitter seat 523 and is located within the emission chamber. The discharge tip 526 can generate a higher electric field strength at a lower voltage. The higher electric field strength can promote the ion emitter 52 to emit ions. By including the discharge tip 526 in the ion emitter 52, the ion emission efficiency can be improved. By locating the discharge tip 526 within the emission chamber, the ion emission cover 524 can, to a certain extent, protect the discharge tip 526, and can also reduce or prevent injuries to users due to accidentally touching the discharge tip 526 or entering the area with higher electric field strength.

[0069] Reference Figure 3-Figure 5 According to some embodiments of the present invention, the ion emitter 52 is located at the airflow outlet 412 of the air duct volute 41, so that ions can be directly blown toward the air outlet 22 along with the airflow in the air duct 414. By locating the ion emitter 52 at the airflow outlet 412 of the air duct volute 41, a certain distance can be maintained between the ions and the fan assembly 44, and the ions' residence time in the air duct 414 is shortened, thereby reducing ion adsorption losses by the fan assembly 44.

[0070] Reference Figure 4 and Figure 5 According to some embodiments of the present invention, the rotation axis of the wind wheel 441 and the air duct volute 41 both extend in the up and down directions, and the ion emitter 52 is located at the upper end of the air duct volute 41, so that when the ions ejected by the ion emitter 52 are impacted by the airflow in the air duct 414, the movement path of the ions can form a parabolic motion trajectory. This parabolic motion trajectory allows the ions to stay in the air duct 414 longer, and also allows the ions to contact the airflow in a larger range, thereby following the airflow toward the air outlet 22 to increase the amount of ions blown out into the room through the air outlet 22.

[0071] Reference Figure 3-Figure 5 According to some embodiments of the present invention, the air duct volute 41 includes two air ducts 414 arranged along the left and right directions, and the fan assembly 44 includes two wind wheels 441. The two wind wheels 441 are respectively located in the two air ducts 414, and the rotation axis of the wind wheel 441 and the air duct volute 41 both extend in the up and down directions. The air outlet 22 is located at the front of the casing assembly 20 and is two arranged along the left and right directions. The two air outlets 22 are respectively connected to the two air ducts 414. The two air outlets 22 can make the air outlet area of ​​the air conditioner larger, thereby increasing the air outlet volume of the air conditioner, and improving the cooling / heating effect of the air conditioner. The two air outlets 22 arranged along the left and right directions can also make the airflow distribution more uniform.

[0072] The high-voltage coil 51 is mounted at the front end of the air duct volute 41 and is located between the two air ducts 414. There are two ion emitters 52. The air duct 414 has a first sidewall 415 and a second sidewall 416 that are oppositely disposed along the width direction. The first sidewall 415 of the two air ducts 414 is located on the side of the two air ducts 414 that is close to each other. The two ion emitters 52 are respectively mounted on the first sidewall 415 of the two air ducts 414. While the high-voltage coil 51 provides the required high voltage electricity to the ion emitters 52, its location between the two air ducts 414 avoids blocking the airflow within the air ducts 414 and increasing airflow resistance. The two ion emitters 52 are located in the two air ducts 414, respectively, ensuring that the airflow within both air ducts 414 can come into contact with the ions, thereby changing the direction of ion movement. This makes the ion distribution of the air blown out by the air conditioner more uniform, and can also effectively increase the amount of ions at the air outlet 22 of the air conditioner, allowing more ions to diffuse into the indoor air, thereby improving the purification and sterilization effect of the air conditioner on the indoor air.

The front volute 411 can support and fix the ion generator 50. The ion generator 50 is installed on the front volute 411, which can ensure that the ion generator 50 is located in the air duct 414, thereby ensuring that ions are ejected toward the air duct 414.

[0075] Reference Figure 4 and Figure 5 According to some embodiments of the present invention, the high-voltage package 51 and the ion emitter 52 are arranged in the up and down directions. While the high-voltage package 51 and the ion emitter 52 are electrically connected to realize the high-voltage package 51 transmitting high voltage to the ion emitter 52, the space inside the air duct volute 41 can be fully utilized, so that the high-voltage package 51 and the ion emitter 52 are arranged in order in this part of the space.

The mounting groove 423 facilitates the assembly of the high-voltage transformer 51 on the intermediate connecting portion 421, making the overall structure of the high-voltage transformer 51 and the intermediate connecting portion 421 compact and facilitating maintenance or replacement of the high-voltage transformer 51.

[0079] Reference Figure 4 、 Figure 5 and Figure 9 According to some embodiments of the present invention, the high-voltage transformer 51 is connected to an input wiring harness 511 and an output wiring harness 512. The input wiring harness 511 is connected to the air conditioner's electrical control box, and the output wiring harness 512 is connected to the ion emitter 52. Both the input wiring harness 511 and the output wiring harness 512 are routed along the intermediate connection portion 421. The electrical control box can supply power to the high-voltage transformer 51 via the input wiring harness 511, and the high-voltage transformer 51 can transmit the high voltage power to the ion emitter 52 via the output wiring harness 512, causing the ion emitter 52 to eject ions. The high-voltage transformer 51 is detachably mounted on the middle connection part 421, and the input wiring harness 511 and the output wiring harness 512 are both routed along the middle connection part 421. The space inside the air duct volute 41 can be fully utilized, so that the high-voltage transformer 51, the input wiring harness 511 and the output wiring harness 512 are arranged in order in the middle connection part 421 of the air duct volute 41, and the high-voltage transformer 51, the input wiring harness 511 and the output wiring harness 512 can be avoided from blocking the air duct 414 and increasing the resistance during airflow.

[0080] In addition, the high-voltage package 51 is located between the two air ducts 414, and the two first side walls 415 are located on the side of the two air ducts 414 close to each other, so that the distance between the high-voltage package 51 and the two ion emitting elements 52 located on the first side walls 415 of the two air ducts 414 is relatively close. In this way, the length of the output wire bundle 512 between the high-voltage package 51 and the two ion emitting elements 52 can be reduced, which can reduce the loss in the energy transmission process to a certain extent.

[0081] Reference Figure 4 、 Figure 5 and Figure 9According to some embodiments of the present invention, the electrical control box is located below the air duct volute 41, and the input wiring harness 511 is routed in the vertical direction. The intermediate connecting portion 421 is provided with a plurality of routing buckles 424 spaced apart in the vertical direction. The routing buckles 424 cooperate with the input wiring harness 511 to limit the position of the input wiring harness 511. The routing buckles 424 can limit the position of the input wiring harness 511, ensuring that the routing position of the input wiring harness 511 on the intermediate connecting portion 421 is accurate. By routing the input wiring harness 511 in the vertical direction and with the plurality of routing buckles 424 spaced apart in the vertical direction, the routing buckles 424 can guide the input wiring harness 511 along the set path, preventing the input wiring harness 511 from becoming entangled with other wiring harnesses, and facilitating subsequent maintenance and troubleshooting.

[0082] For example, the routing buckle 424 can define a routing space together with the intermediate connecting part 421, and at least part of the input wiring harness 511 can be accommodated in the routing space, which can make the overall structure of the input wiring harness 511 and the intermediate connecting part 421 compact, and can play a certain protective role for the input wiring harness 511, reducing or avoiding damage to the input wiring harness 511 caused by external components.

[0083] Reference Figure 4 and Figure 5 According to some embodiments of the present invention, the high-voltage coil 51 is located below the ion emitter 52. Since the electronic control box is located below the air duct volute 41, the high-voltage coil 51 is located below the ion emitter 52, so that the distance between the high-voltage coil 51 and the electronic control box is closer. This can reduce the length of the input wiring harness 511 between the high-voltage coil 51 and the electronic control box, and to a certain extent reduce the loss in the energy transmission process.

By having two ion emitting elements 52 located in two air ducts 414 respectively, it can be ensured that ions can flow smoothly toward the corresponding air outlet channels 251 and then diffuse into the indoor air through the corresponding air outlets 22, thereby achieving the sterilization and air purification effects of the air conditioner.

With ions located at the air outlet 412, the forward-flowing airflow redirects the ion movement, directing the ions as far forward as possible. This reduces the amount of ions adsorbed by the air guide assembly at the air outlet 22, thereby effectively increasing the amount of ions blown into the room.
