Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an air conditioner. Background Technology

[0002] As people's demands for quality of life continue to rise, air conditioners, equipped with ion generators, produce ions. The airflow blown into the room contains these ions, which can purify and sterilize the indoor air, improving the user experience. However, these ion generators are often located at the air outlet, which is typically equipped with air guide components to regulate the airflow direction. Ions are easily adsorbed by these components, making it difficult for them to diffuse into the indoor air, thus reducing the effectiveness of ion sterilization and air purification. This issue needs to be addressed. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide an air conditioner in which an ion generator is installed in the duct casing, and the ion emitter is located downstream of the impeller. This extends the distance between the ion emitter and the air outlet. Within this longer distance, the impeller drives the airflow to flow forward from back to front. This forward-flowing airflow alters the direction of ion movement, causing the ions to flow as far forward as possible. This reduces the amount of ions adsorbed by the air guide components at the air outlet, effectively increasing the amount of ions blown into the room. This enhances the sterilization and air purification effects of the ions blown out by the air conditioner.

[0044] 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.

[0045] The following is for reference. Figures 1-11This invention describes an air conditioner according to an embodiment of the present invention.

[0046] Reference Figure 1 , Figure 2 and Figure 4 An air conditioner according to an embodiment of the present invention includes a housing assembly 20, an air duct assembly 40, a heat exchanger assembly 30, and an ion generator 50. The housing assembly 20 has an air inlet 21 and an air outlet 22. The air duct assembly 40 is disposed within 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, and the impeller 441 of the fan assembly 44 is located within the air duct 414. The heat exchanger assembly 30 is disposed within the housing assembly 20 and is located between the air duct assembly 40 and the air inlet 21. The ion generator 50 is disposed within the housing assembly 20 and is installed in the air duct volute 41. The ion generator 50 includes a high-voltage transformer 51 electrically connected to an ion emitter 52, and the ion emitter 52 is located downstream of the impeller 441. When the air conditioner is working, the fan wheel 441 drives the airflow through the air inlet 21 into the casing assembly 20 and flows to the heat exchanger assembly 30. After the airflow is heated by the heat exchanger assembly 30, it flows toward the air duct 414. The airflow in the air duct 414 is blown out to the room through the air outlet 22 to heat or cool the room.

[0047] The high-voltage transformer 51 is electrically connected to the ion emitter 52, providing the necessary high-voltage electricity to ensure that the ion emitter 52 can generate ions, such as negative ions. With the ion generator 50 located within the housing assembly 20 and the ion emitter 52 positioned downstream of the impeller 441, these negative ions can flow with the airflow in the duct 414 towards the air outlet 22 as the airflow moves. They are then blown into the room through the air outlet 22. For example, the presence of negative ions in the airflow can purify the air, removing bacteria, viruses, dust, and other fine particulate matter, thus improving the user experience.

[0048] For example, an air guide component for adjusting the airflow direction is provided at the air outlet 22. The air guide component can be an air guide plate or a louver mechanism, etc., and the nozzle of the ion emitter 52 faces downward, so that the negative ion is sprayed downward. If the ion emitter 52 is located at the air outlet 22, more of the negative ions sprayed by the ion emitter 52 will be directly absorbed by the air guide component at the air outlet 22, resulting in too few negative ions being blown into the room from the air outlet 22, resulting in poor air sterilization and air purification effect of the air conditioner.

[0049] By installing an ion generator 50 on the duct housing 41 and placing the ion emitter 52 downstream of the impeller 441, the distance between the ion emitter 52 and the air outlet 22 is extended. During the airflow within the duct 414, the negative ions follow the airflow over this longer distance, altering their spray direction. For example, the nozzle of the ion emitter 52 points downwards, causing the negative ions to spray downwards. The impeller 441 drives the airflow forward from back to front. This forward-flowing airflow alters the direction of negative ion movement, directing them forward rather than downward. Consequently, when the negative ions pass through the air outlet 22, their flow direction is closer to horizontal. This reduces the amount of negative ions adsorbed by the air guide components at the air outlet 22, effectively increasing the amount of negative ions blown into the room. This allows more negative ions to diffuse into the indoor air, enhancing the air conditioner's sterilization and air purification effects.

[0050] For example, a rotatable air guide plate is provided at the air outlet 22. The air guide plate has diffuser holes that penetrate the air guide plate along its thickness direction. When the air guide plate is in the closed position, the ion generator 50 is installed on the duct housing 41 and the ion emitter 52 is located downstream of the impeller 441. This can extend the distance between the ion emitter 52 and the air outlet 22. When the airflow flows in the duct 414, within this longer distance, for example, if the negative ion jet direction is downward, the forward-flowing airflow can change the movement direction of the negative ions so that the negative ions flow forward as much as possible. When the negative ions flow through the air outlet 22, the flow direction of the negative ions is closer to the thickness direction of the air guide plate. This can effectively reduce the amount of negative ions adsorbed by the air guide plate, allowing more negative ions to flow out from the diffuser holes, thereby achieving better air purification and sterilization effects.

[0051] According to the embodiment of the present invention, the air conditioner has an ion generator 50 installed on the duct volute 41, and the ion emitter 52 is located downstream of the impeller 441. This extends the distance between the ion emitter 52 and the air outlet 22. During this longer distance, the impeller 441 drives the airflow to flow forward from back to front. The forward-flowing airflow can change the direction of ion movement so that the ions flow forward as much as possible. This reduces the amount of ions adsorbed by the air guide component at the air outlet 22, thereby effectively increasing the amount of ions blown into the room. This is beneficial for enhancing the effect of the ions blown out by the air conditioner on sterilizing and purifying the indoor environment.

[0052] Reference Figures 2-4According to some embodiments of the present invention, the ion emitter 52 is installed in the air duct 414, so that the airflow in the air duct 414 can directly drive the flow of negative ions, thereby effectively changing the flow direction of negative ions and enabling negative ions to move as far as possible toward the air outlet 22.

[0053] Reference Figure 3 , Figure 4 and Figure 6 According to some embodiments of this utility model, the ion emitter 52 is located at the airflow outlet 412 of the duct volute 41, so that ions can be directly blown towards the air outlet 22 along with the airflow in the duct 414. By positioning the ion emitter 52 at the airflow outlet 412 of the duct volute 41, a certain distance can be maintained between the ions and the fan assembly 44, and the residence time of the ions in the duct 414 is shorter, which can reduce the adsorption loss of ions by the fan assembly 44.

[0054] Reference Figure 4 , Figure 6 and Figure 8 According to some embodiments of this utility model, the rotation axis of the impeller 441 and the volute 41 of the air duct extend in the vertical direction. The ion emitter 52 is arranged along the width direction of the air duct 414, which is perpendicular to the vertical direction. By arranging the ion emitter 52 along the width direction of the air duct 414, the ions released by the ion emitter 52 can more evenly cover the entire cross section of the air duct, thereby ensuring that the airflow can contact the ions and effectively change the direction of ion movement, so that the ions follow the airflow towards the air outlet 22 as much as possible.

[0055] Reference Figure 4 , Figure 6 and Figure 8 According to some embodiments of the present invention, the ion emitter 52 includes an ion emitter head 521, which is located in the middle of the air duct 414 in the width direction of the air duct 414. This can extend the distance between the ion emitter head 521 and the wall of the air duct 414, reducing or avoiding the possibility of ion adsorption on the wall of the air duct 414. Furthermore, the ion emitter head 521 being located in the middle of the air duct 414 can also allow ions to cover both sides of the air duct 414 as much as possible, ensuring that the airflow on both sides of the air duct 414 can come into contact with ions when flowing, thereby allowing more ions to flow towards the air outlet 22 with the airflow.

[0056] For example, if the ion emitter 521 is closer to one side of the air duct 414 in the width direction, the ions may have difficulty flowing to the area on the other side of the air duct 414. By positioning the ion emitter 521 in the middle of the air duct 414 in the width direction, this dead zone can be reduced, allowing the ions to cover the entire flow section of the air duct 414 as much as possible.

[0057] Reference Figure 4 , Figure 6 and Figure 8 According to some embodiments of this utility model, the rotation axis of the impeller 441 and the duct volute 41 both extend in the vertical direction. The ion emitter 52 is located at the upper end of the duct volute 41. This allows the ions ejected by the ion emitter 52 to form a parabolic trajectory when impacted by the airflow in the duct 414. This parabolic trajectory allows the ions to stay in the duct 414 for a longer time and also allows the ions to come into contact with the airflow over a larger area, thereby following the airflow toward the air outlet 22 to increase the amount of ions blown into the room through the air outlet 22.

[0058] Reference Figure 4 , Figure 6 and Figure 8 According to some embodiments of this utility model, the ion emitter 521 faces downward, and the ions can use their own gravity to make more ions come into contact with the airflow in the air duct 414, thereby enabling the airflow to effectively change the direction of ion movement and increase the amount of ions blown into the room through the air outlet 22.

[0059] Reference Figure 3 , Figure 4 and Figure 6 According to some embodiments of the present invention, an installation bracket 415 is provided inside the air duct 414. The installation bracket 415 is connected to the air duct volute 41. The ion emitter 52 is installed on the installation bracket 415. The installation bracket 415 can facilitate the connection of the ion emitter 52 on the air duct volute 41, and the installation bracket 415 can support and fix the ion emitter 52.

[0060] Reference Figure 7 , Figure 8 and Figure 10 According to some embodiments of the present invention, the ion emitter 52 is snapped onto the mounting bracket 415, which makes the connection between the ion emitter 52 and the mounting bracket 415 simple and has strong stability. The snap-fit ​​connection between the ion emitter 52 and the mounting bracket 415 makes the installation or removal of the ion emitter 52 and the mounting bracket 415 more convenient.

[0061] Reference Figure 8 , Figure 10 and Figure 11According to some embodiments of the present invention, the mounting bracket 415 is provided with a socket 416, and the ion emitter 52 is provided with a pin 523. The pin 523 is inserted into the socket 416. Through the plug-in connection between the pin 523 and the socket 416, the connection between the ion emitter 52 and the mounting bracket 415 can be simple and has strong stability, making the installation or disassembly of the ion emitter 52 and the mounting bracket 415 simpler.

[0062] Optionally, the ion emitter 52 also includes an ion emitter frame 522, which has a pin 523 that inserts into a socket 416. The ion emitter head 521 is mounted on the ion emitter frame 522, which provides fixation and support for the ion emitter head 521. By inserting the pin 523 on the ion emitter frame 522 into the socket 416 of the mounting bracket 415, a plug-in connection can be achieved between the ion emitter frame 522 and the mounting bracket 415, thereby achieving a fixed connection of the ion emitter 52 on the mounting bracket 415.

[0063] Reference Figures 8-10 According to some embodiments of the present invention, a first mounting groove 417 is formed on the mounting bracket 415, and the ion emitter 52 is mounted in the first mounting groove 417. The first mounting groove 417 can facilitate the ion emitter 52 to be accommodated therein, thereby facilitating the assembly of the ion emitter 52 on the mounting bracket 415, and making the overall structure of the ion emitter 52 and the mounting bracket 415 compact.

[0064] Reference Figure 7 , Figure 8 and Figure 10 According to some embodiments of this utility model, the rotation axis of the impeller 441 and the duct volute 41 both extend in the vertical direction. Multiple reinforcing support members 418 are arranged at intervals in the vertical direction within the duct 414. Each reinforcing support member 418 is connected to two side walls in the width direction of the duct 414, and at least some of the reinforcing support members 418 constitute a mounting bracket 415. The side walls can support and fix the reinforcing support members 418, and the reinforcing support members 418 can enhance the overall structural strength of the duct assembly 40. By having at least some of the reinforcing support members 418 constitute the mounting bracket 415, the overall structural strength of the mounting bracket 415 can be enhanced, thereby improving the supporting effect of the mounting bracket 415 on the ion emitter 52.

[0065] Wherein, at least a portion of the reinforcing support member 418 constitutes the mounting bracket 415, which may include the following situations: for example, a portion of the reinforcing support member 418 may constitute the mounting bracket 415; as another example, a portion of the reinforcing support member 418 may constitute the mounting bracket 415.

[0066] In the description of this utility model, "multiple" means two or more.

[0068] A high-voltage transformer 51 is installed at the front end of the duct housing 41 and is located between two ducts 414. Two ion emitters 52 are located within the two ducts 414 respectively. While the high-voltage transformer 51 provides the necessary high-voltage electricity to the ion emitters 52, its location between the two ducts 414 avoids obstructing airflow and increasing airflow resistance. The two ion emitters 52, located within the two ducts 414 respectively, ensure that the airflow within both ducts 414 can contact the ions to change their direction of movement, resulting in a more uniform distribution of ions emitted by the air conditioner. This also effectively increases the amount of ions at the air outlet 22, allowing more ions to diffuse into the indoor air, thereby improving the air conditioner's purification and sterilization effects.

[0069] Reference Figure 3-Figure 5 According to some embodiments of this utility model, the air duct volute 41 includes a detachably connected front volute 411 and an air duct baffle 413. The front volute 411 and the air duct baffle 413 are detachably connected, making maintenance or replacement of either the air duct baffle 413 or the front volute 411 more convenient. The front volute 411 and the air duct baffle 413 together define two air ducts 414, with the air duct baffle 413 located between the two air ducts 414. The ion generator 50 is installed on the front volute 411. The air duct baffle 413, located between the two air ducts 414, ensures isolation between the two air ducts 414, preventing airflow interference between the two channels. The front volute 411 provides support and fixation for the ion generator 50. The installation of the ion generator 50 on the front volute 411 ensures that the ion generator 50 is located within the air duct 414, thereby ensuring that ions are sprayed towards the air duct 414.

[0070] Reference Figure 3-Figure 5According to some embodiments of the present invention, the front volute 411 includes a left volute portion 419, a right volute portion 420, and a middle connecting portion 421. In the left-right direction, the middle connecting portion 421 is located between the left volute portion 419 and the right volute portion 420. The middle connecting portion 421, the left volute portion 419, and the right volute portion 420 together define two air ducts 414. The middle connecting portion 421 defines a receiving space 422, which is located between the two air ducts 414. The high-voltage pack 51 is installed in the middle connecting portion 421 and is located in the receiving space 422. The accommodating space 422 facilitates the housing of the high-voltage transformer 51, making the assembly of the high-voltage transformer 51 on the intermediate connecting part 421 more convenient and allowing the overall structure of the high-voltage transformer 51 and the intermediate connecting part 421 to be more compact. Furthermore, the installation of the high-voltage transformer 51 on the intermediate connecting part 421 between the left volute 419 and the right volute 420 allows the high-voltage transformer 51 to be closer to the ion emitters 52 located in the two air ducts 414. This reduces the length of the wiring harness between the high-voltage transformer 51 and the two ion emitters 52, thereby reducing energy loss during transmission to some extent.

[0074] Reference Figure 4-Figure 6 According to some embodiments of this utility model, the high-voltage transformer 51 is connected to an input harness 511 and an output harness 512. The input harness 511 is connected to the control box of the air conditioner, and the output harness 512 is connected to the ion emitter 52. Both the input harness 511 and the output harness 512 are routed along the intermediate connection portion 421. The control box can supply power to the high-voltage transformer 51 via the input harness 511, so that the high-voltage transformer 51 can transmit high-voltage electricity to the ion emitter 52 via the output harness 512, so that the ion emitter 52 can eject ions. The high-voltage transformer 51 is detachably installed in the intermediate connection part 421, and the input harness 511 and the output harness 512 are both routed along the intermediate connection part 421. This makes full use of the space inside the air duct housing 41, so that the high-voltage transformer 51, the input harness 511 and the output harness 512 are arranged in an orderly manner in the intermediate connection part 421 of the air duct housing 41. This also avoids the high-voltage transformer 51, the input harness 511 and the output harness 512 from blocking the air duct 414 and increasing the resistance to airflow.

[0075] Reference Figure 4-Figure 6 According to some embodiments of this utility model, the electrical control box is located below the duct housing 41. The input wiring harness 511 is routed vertically. Multiple wiring clips 424, spaced vertically, are provided on the intermediate connecting part 421. The wiring clips 424 cooperate with the input wiring harness 511 to limit its position. The wiring clips 424 limit the input wiring harness 511, ensuring accurate positioning of the input wiring harness 511 on the intermediate connecting part 421. By routed vertically and spaced vertically, the wiring clips 424 guide the input wiring harness 511 along a predetermined path, preventing it from tangling with other wiring harnesses and facilitating later maintenance and troubleshooting.

[0076] For example, the wiring clip 424 can define a wiring space with the intermediate connection part 421. At least part of the input wire harness 511 is accommodated in the wiring space, which can make the overall structure of the input wire harness 511 and the intermediate connection part 421 compact, and can play a certain protective role for the input wire harness 511, reducing or avoiding damage to the input wire harness 511 caused by external components.

[0077] Reference Figure 7, Figure 8 and Figure 10 According to some embodiments of this utility model, a first limiting buckle 425 is provided on the intermediate connecting part 421, and a second limiting buckle 524 is provided on the ion emitter 52. The second limiting buckle 524 is engaged with the first limiting buckle 425. The first limiting buckle 425 can limit the ion emitter 52, ensuring that the assembly position of the ion emitter 52 on the air duct volute 41 is accurate. The engagement between the second limiting buckle 524 and the first limiting buckle 425 can realize the engagement connection between the ion emitter 52 and the intermediate connecting part 421. This makes the connection between the ion emitter 52 and the intermediate connecting part 421 simple and has strong stability. The engagement connection between the ion emitter 52 and the intermediate connecting part 421 makes it more convenient to install or remove the ion emitter 52 on the intermediate connecting part 421.

[0078] For example, the assembly process of the ion generator 50 on the duct housing 41 can be as follows: the pin 523 of the ion emitter 52 is inserted into the socket 416, the second limiting buckle 524 on the ion emitter 52 is engaged with the first limiting buckle 425 on the intermediate connecting part 421, so that the ion emitter 52 is more stably installed on the mounting bracket 415, and the high voltage transformer 51 is installed in the second mounting groove 423 of the intermediate connecting part 421. The input wiring harness 511 is connected to the electrical control box. The input wiring harness 511 and the output wiring harness 512 are both routed along the intermediate connecting part 421 and the wiring buckle 424 cooperates with the input wiring harness 511 to limit the input wiring harness 511, thus completing the assembly process of the ion generator 50 on the duct housing 41.

[0079] For example, the disassembly process of the ion generator 50 on the duct housing 41 can be as follows: the second limiting buckle 524 of the ion emitter 52 is disengaged from the first limiting buckle 425 on the intermediate connecting part 421, and the pin 523 of the ion emitter 52 is disengaged from the socket 416 to remove the ion emitter 52 from the mounting bracket 415. The high voltage transformer 51 is removed from the second mounting groove 423, the connection between the input harness 511 and the control box is disconnected, and the connection between the wiring buckle 424 and the input harness 511 is disconnected, thus completing the disassembly process of the ion generator 50 on the duct housing 41.

The second cover 453 is disposed on the air duct baffle 413 and is integrally formed with the air duct baffle 413. This can enhance the overall structural strength of the second cover 453 and the air duct baffle 413 to a certain extent, and can eliminate the assembly process between the second cover 453 and the air duct baffle 413.

Each reinforcing support member 418 is connected to two side walls in the width direction of the air duct 414, and at least some of the reinforcing support members 418 form a mounting bracket 415. The intermediate connecting part 421 is provided with a first limiting buckle 425 and the intermediate connecting part 421 forms a second mounting groove 423.

[0094] The ion emitter 52 is located at the upper end of the duct housing 41. The ion emitter 52 includes an ion emitter head 521, which is located in the middle of the duct 414 in the width direction and faces downwards. The ion emitter 52 is provided with a second limiting buckle 524, which engages with a first limiting buckle 425. The ion emitter 52 is engaged with a mounting bracket 415, which has a first mounting groove 417. The ion emitter 52 is mounted in the first mounting groove 417. The mounting bracket 415 also has an insertion hole 416, and the ion emitter 52 has a pin 523 inserted into the insertion hole 416. The high-voltage transformer 51 is detachably mounted in the second mounting groove 423.

[0095] The high-voltage transformer 51 is connected to an input harness 511 and an output harness 512.

[0096] The electrical control box is located below the duct housing 41, and the input wiring harness 511 is routed in the vertical direction. The middle connecting part 421 is provided with multiple wiring clips 424 arranged at intervals in the vertical direction. The wiring clips 424 cooperate with the input wiring harness 511 to limit the input wiring harness 511.

[0097] For example, the assembly process of the ion generator 50 on the duct housing 41 can be as follows: the pin 523 of the ion emitter 52 is inserted into the socket 416, the second limiting buckle 524 on the ion emitter 52 is engaged with the first limiting buckle 425 on the intermediate connecting part 421, so that the ion emitter 52 is more stably installed on the mounting bracket 415, and the high voltage transformer 51 is installed in the second mounting groove 423 of the intermediate connecting part 421.

[0099] When the air conditioner is working, the fan wheel 441 drives the airflow through the air inlet 21 into the casing assembly 20 and towards the heat exchanger assembly 30. After heat exchange in the heat exchanger assembly 30, the airflow flows towards the air duct 414. The airflow in the air duct 414 flows towards the air outlet 251 and is then blown out into the room through the air outlet 22 to heat or cool the room. The ions emitted by the ion emitter 52 flow downwards. Because the ions are located at the air outlet 412, the forward-flowing airflow can change the direction of ion movement, causing the ions to flow forward as much 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.
