DETAILED DESCRIPTION

[0043] The following describes in detail embodiments of the present application. 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 only used to explain the present application and are not to be construed as limiting the present application.

[0044] The air conditioner according to an embodiment of the present application is described below with reference to Figures 1 to 13.

[0045] With reference to Figures 1 to 8, an air conditioner according to an embodiment of the present application includes: a housing 1, a fan component 2, a heat exchanger component 3, and a purification device, wherein the fan component 2, the heat exchanger component 3, and the purification device are disposed within the housing 1. The housing 1 has an air inlet 11 and an air outlet 12. The heat exchanger component 3 is disposed within the housing 1 and is located between the air inlet 11 and the fan component 2. A mounting cavity 4 is defined between the heat exchanger component 3 and the housing 1, which is opposite to and in communication with the air inlet 11. The purification device includes a purification assembly, which is detachably mounted within the mounting cavity 4 in a front-to-rear direction. Thus, when the purification assembly needs to be cleaned, repaired, or replaced, it is no longer necessary to laboriously disassemble and assemble the purification assembly from the top of the air conditioner. Instead, the purification assembly can be conveniently installed or removed from the front side of the air conditioner, thereby facilitating maintenance of the purification assembly.

[0046] The purification assembly includes a purification module 511 and a filter provided on the purification module 511. The filter is located on the side of the purification module 511 adjacent to the air inlet 11. Driven by the fan component 2, the air entering the housing 1 from the air inlet 11 first flows through the filter and is filtered by the filter. The filtered air then flows to the purification module 511 and is further purified by the purification module 511. By providing a purification device, the air entering the housing 1 can be purified to improve the air quality of the air. By providing the filter on the purification module 511, the filter can make full use of the space on the side of the purification module 511 adjacent to the air inlet 11, which is conducive to reducing the installation space occupied by the filter and the purification module 511 on the air conditioner, making the structure inside the air conditioner more compact, and also conducive to the miniaturization design of the air conditioner.

[0047] For example, the filter can filter out foreign matter such as dust, hair, and mosquitoes in the air. The air passes through the filter before entering the purification module 511, which can prevent foreign matter such as dust, hair, and mosquitoes in the air from entering the purification module 511, thereby preventing these foreign matter from adversely affecting the purification function of the purification module 511.

[0048] For example, the purification module 511 may have purification functions such as dust removal, odor removal, dehumidification, formaldehyde removal, removal of harmful bacteria, and disinfection.

[0049] When the air conditioner is working, the fan component 2 drives the air flow from the air inlet 11 into the casing 1, and the air flows through the filter screen and purification module 511 of the purification component in turn. Then, the air purified by the purification component flows to the heat exchanger component 3 and exchanges heat with the heat exchanger component 3. Then, the air after heat exchange is discharged into the room from the air outlet 12 under the driving action of the fan component 2, thereby adjusting the indoor temperature.

[0050] For example, the process of installing the purification component in the installation cavity 4 may include the following steps: first, installing the purification module 511 in the installation cavity 4 along the front-to-back direction; then, installing the filter on the purification module 511 along the front-to-back direction.

[0051] For example, the process of installing the purification component in the installation cavity 4 may include the following steps: first, installing the filter on the purification module 511; then, installing the filter and the purification module 511 together in the installation cavity 4 along the front-to-back direction.

[0052] Optionally, the air conditioner can be a split-type air conditioner, for example, the air conditioner can be a split-type wall-mounted air conditioner, the air conditioner includes an air-conditioning indoor unit 100 and an air-conditioning outdoor unit, the air-conditioning indoor unit 100 includes the above-mentioned casing 1, fan component 2, heat exchanger component 3 and purification device, and the air inlet 11 can be formed at the top of the casing 1.

[0053] For example, if the purification module 511 and the filter of the air conditioner's purification assembly are located at the air inlet 11 at the top of the housing 1, since the indoor unit 100 of a split wall-mounted air conditioner is usually located near the indoor ceiling, the distance between the purification module 511 and the filter and the indoor ceiling is small. When cleaning or replacing the purification module 511 and the filter, one needs to laboriously reach from the top of the housing 1 between the air conditioner and the indoor ceiling, and then remove or install the purification module 511 and the filter from the top of the housing 1, which is inconvenient. However, if the purification module 511 and the filter of the purification assembly are detachably installed in the installation cavity 4 along the front-to-back direction, the purification module 511 and the filter can be removed or installed from the front side of the air conditioner. The front side of the air conditioner has ample operating space and is relatively low, making related operations more convenient.

[0054] According to the air conditioner of the embodiment of the present application, by making the purification component include a purification module 511 and a filter, and making the filter provided on the purification module 511, the filter can make full use of the space on the purification module 511 adjacent to the air inlet 11, which is beneficial to reducing the installation space occupied by the purification module 511 and the filter on the air conditioner and is beneficial to the miniaturization of the air conditioner; by making the purification component detachably installed in the installation cavity 4 along the front-to-back direction, it is convenient to disassemble and assemble the purification module 511 and the filter from the front side of the air conditioner, thereby facilitating the cleaning or replacement of the purification module 511 and the filter.

[0055] With reference to Figures 1 and 2, according to some embodiments of the present application, the air conditioner further includes an air guide plate 15, which is disposed at the air outlet 12 of the housing 1. The air guide plate 15 can be moved to open or close the air outlet 12. Air dispersion holes 16 are also provided on the inner side of the air guide plate 15. Optionally, when the air guide plate 15 is in a position closing the air outlet 12, the air dispersion holes 16 can be opened, allowing air exhausted from the air outlet 12 to enter the room through the air dispersion holes 16. This allows the air conditioner to have multiple air supply modes, which is conducive to meeting the different usage needs of users.

[0056] Referring to Figures 10 and 11 , according to some embodiments of the present application, the filter and purification module 511 are detachably connected. For example, the filter and purification module 511 are connected via a fastening connection, a snap-on connection, or other similar connection methods. The detachable connection between the filter and purification module 511 facilitates separate maintenance, such as cleaning and replacement, of the filter and purification module 511.

[0057] 10-11 , according to some optional embodiments of the present application, the filter is detachably mounted on the purification module 511 along the front-to-back direction, and the purification module 511 is detachably mounted in the installation cavity 4 along the front-to-back direction. By detachably mounting the filter on the purification module 511 along the front-to-back direction, and detachably mounting the purification module 511 in the installation cavity 4 along the front-to-back direction, the filter and the purification module 511 can be conveniently assembled and disassembled from the front side of the air conditioner; when the filter alone needs to be cleaned or replaced, the filter can be conveniently assembled or disassembled from the front side of the air conditioner, thereby facilitating relevant maintenance on the filter; when the purification module 511 needs to be cleaned, repaired, or replaced alone, the filter can also be conveniently disassembled from the purification module 511 before relevant maintenance operations are performed on the purification module 511.

[0058] With reference to Figures 10-11, according to some optional embodiments of the present application, a guide and retaining groove 5111 is formed on the purification module 511. The edge of the filter is received in the guide and retaining groove 5111 to retain the filter. By forming the guide and retaining groove 5111 on the purification module 511, the guide and retaining groove 5111 provides guidance and retaining effect on the filter disposed on the purification module 511. This guiding effect allows the filter to be accurately installed on the purification module 511. Furthermore, the retaining effect of the guide and retaining groove 5111 on the filter facilitates stable installation of the filter on the purification module 511.

[0059] Referring to Figures 10 and 11 , according to some optional embodiments of the present application, guide slots 5111 are formed on the left and right ends of the purification module 511, respectively. The left and right ends of the filter are respectively accommodated in the two guide slots 5111. During installation and removal of the filter, the left and right ends of the filter can slide relative to the guide slots 5111 in the front-to-back direction, allowing the filter to be removably mounted on the purification module 511 in this direction. For example, the filter can be slid from front to back, guided by the guide slots 5111, and removed from the purification module 511 in the back-to-front direction. By making the filter removable in the front-to-back direction, the filter can be easily installed or removed from the front side of the air conditioner when cleaning or replacement is required, thereby facilitating filter maintenance.

[0060] With reference to Figures 10 and 11, according to some optional embodiments of the present application, the guide limit slot 5111 includes a limit section 5113 and a guide section 5112. The guide section 5112 is connected to the front side of the limit section 5113. The guide section 5112 gradually decreases in size along the thickness direction of the filter in the direction of filter insertion. When inserting the filter into the guide limit slot 5111, the filter slides from the guide section 5112 to the limit section 5113; when removing the filter from the guide limit slot 5111, the filter slides from the limit section 5113 to the guide section 5112. By gradually decreasing the guide section 5112 in the thickness direction of the filter in the direction of filter insertion, the space in front of the guide section 5112 is larger, facilitating the insertion and removal of the filter.

[0061] 10-11 , according to some embodiments of the present application, a disassembly handle 5114 is provided at the front end of the purification module 511. Providing the disassembly handle 5114 at the front end of the purification module 511 facilitates installation of the purification module 511 in the installation cavity 4 along the front-to-back direction using the disassembly handle 5114, and facilitates removal of the purification module 511 from the installation cavity 4 along the front-to-back direction using the disassembly handle 5114.

[0062] 1-5 , according to some embodiments of the present application, the purification module 511 is in an arc shape that curves toward the air inlet 11. By making the purification module 511 in an arc shape that curves toward the air inlet 11, the purification module 511 can better match the structure of the heat exchanger, so that the purification module 511 can fully utilize the space defined between the heat exchanger component 3 and the air inlet 11 of the housing 1, which is conducive to increasing the purification area of ​​the purification module 511. It can also prevent the purification module 511 from interfering with or colliding with the heat exchanger during installation in the installation cavity 4 or during removal from the installation cavity 4, thereby making it easier to install the purification module 511 in the installation cavity 4 and fully utilizing the space within the installation cavity 4.

[0063] According to some embodiments of the present application, the filter is in an arc shape that curves toward the air inlet 11. By making the filter in an arc shape that curves toward the air inlet 11, the filter can better match the structure of the purification module 511, making it easier to install the filter in the purification module 511.

[0064] With reference to Figures 1-5, according to some optional embodiments of the present application, a housing 1 includes a face frame 13 and a panel 14. An air inlet 11 is formed on the top of the face frame 13, and an installation opening 131 is formed on the front side of the face frame 13. The installation opening 131 is opposite to and communicates with the installation cavity 4. The purification assembly can be placed into or removed from the installation cavity 4 through the installation opening 131. The panel 14 is mounted on the front side of the face frame 13 and can be opened by movement. For example, the process of installing the purification assembly into the installation cavity 4 is as follows: first, the panel 14 is moved to open the front side of the face frame 13, exposing the installation opening 131 on the front side of the face frame 13; then, the purification assembly is placed into the installation cavity 4 through the installation opening 131. For example, the process of removing the purification assembly from the installation cavity 4 is as follows: first, the panel 14 is moved to open the front side of the face frame 13, exposing the installation opening 131 on the front side of the face frame 13; then, the purification assembly is removed from the installation cavity 4 through the installation opening 131. By forming the installation opening 131 on the front side of the face frame 13 , it is convenient to install or remove the purification component at the installation opening 131 , and other components of the air conditioner can be prevented from interfering with the installation or removal of the purification component.

[0065] 1-13 , according to some optional embodiments of the present application, the purification module 511 includes a purification bracket 512 and a purification core 513. The purification bracket 512 is formed with a ventilation cavity 5121. The purification core 513 is mounted in the ventilation cavity 5121. The filter is mounted on the purification bracket 512 and is located on a side of the purification core 513 adjacent to the air inlet 11. The purification core 513 includes an electrostatic dust removal component 5131. The purification device includes a high-voltage power supply 52, which is electrically connected to the electrostatic dust removal component 5131 to power the electrostatic dust removal component 5131. Air entering the housing 1 through the air inlet 11 first flows through the filter, and then the filtered air flows toward the ventilation cavity 5121 of the purification bracket 512 and flows through the purification core 513, which purifies the air.

[0066] Optionally, the purification bracket 512 is an insulating member, for example, the purification bracket 512 may be a plastic member, which can avoid the risk of electric shock caused by accidentally touching the purification bracket 512 .

[0067] For example, the electrostatic dust removal assembly 5131 includes a dust collecting sheet and a fixing card, and the dust collecting sheet can be installed on the purification bracket 512 via the fixing card. There are multiple dust collecting sheets spaced apart along the first direction, and the fixing card is formed with multiple slots spaced apart. The multiple dust collecting sheets are respectively inserted into the multiple slots. The fixing card is detachably connected to the purification bracket 512, so that the dust collecting sheet can be detachably connected to the purification bracket 512 by being inserted into the slots of the fixing card. The connection between the dust collecting sheet and the fixing card is simple, which facilitates installation and removal operations. By making the fixing card detachable from the purification bracket 512, the dust collecting sheet is inserted into the slot of the fixing card, which makes it convenient to maintain and replace the fixing card and the dust collecting sheet. Moreover, if it is found that the dust collecting sheet or the fixing card has quality problems or is installed incorrectly during the installation of the electrostatic dust removal assembly 5131 on the purification bracket 512, adjustments can be made in a timely manner.

[0068] Gaps are formed between the multiple dust collecting sheets. When the air entering the purification module 511 flows through the electrostatic dust removal component 5131, it will enter these gaps between the dust collecting sheets, so that the multiple dust collecting sheets can absorb and collect particulate dust in the air to perform a purification function.

[0069] High-voltage power supply 52, also known as a high-voltage generator, is used to generate high voltage. After boosting the voltage, high-voltage power supply 52 transmits the boosted voltage to electrostatic precipitator assembly 5131 to meet the high-voltage power requirements of electrostatic precipitator assembly 5131. By providing high-voltage power supply 52, high-voltage power supply 52 can power electrostatic precipitator assembly 5131 of the purification assembly, thereby enabling the electrostatic precipitator components of electrostatic precipitator assembly 5131 to perform their electrostatic precipitator functions, allowing the purification device to perform its purification function and improve air quality.

[0070] By making the purification core 513 an electrostatic dust removal component 5131, the electrostatic dust removal component 5131 has an electrostatic dust removal function and can absorb particles, dust, etc. in the air flowing through the purification core 513. The electrostatic dust removal component 5131 can be reused by cleaning and no longer needs to be replaced frequently.

[0071] According to some optional embodiments of the present application, a plurality of ventilation holes 5122 are further formed on the purification bracket 512, and the plurality of ventilation holes 5122 are located on a side of the purification bracket 512 that is bent toward the direction close to the air outlet 12, and the plurality of ventilation holes 5122 are spaced apart along the left and right directions. Optionally, the plurality of ventilation holes 5122 are connected to the ventilation cavity 5121, and the plurality of ventilation holes 5122 are arranged relative to a portion of the purification core 513. By forming a plurality of ventilation holes 5122 on the purification bracket 512, the wind resistance of the purification bracket 512 to the air can be reduced, which is conducive to the air entering from the air inlet 11 to flow more smoothly through the purification module 511; and more air can flow toward the purification core 513 through the ventilation holes 5122 to obtain the purification effect of the purification core 513, which is conducive to improving the purification effect of the air conditioner.

[0072] According to some optional embodiments of the present application, the air conditioner includes an electronic control box, which is arranged in the casing 1. The high-voltage power supply 52 has an input wiring harness and the input wiring harness is electrically connected to the electronic control box. The electronic control box can be electrically connected to an external power supply, and the electronic control box can supply power to the high-voltage power supply 52.

[0073] When the air conditioner is working, the high-voltage power supply 52 supplies power to the electrostatic dust removal component 5131 of the purification module 511. The electrical control box of the air conditioner can control whether the electrostatic dust removal component 5131 is working through the high-voltage power supply 52. ​​If the electrostatic dust removal component 5131 is working, the purification module 511 can purify part of the air entering the casing 1 to remove particles, dust, etc. contained in the air entering the casing 1.

[0078] 1-5 , according to some optional embodiments of the present application, the housing 1 includes a face frame 13 and a panel 14. An air inlet 11 is formed at the top of the face frame 13, and a mounting port 131 and a mounting groove 132 are formed on the front side of the face frame 13. The mounting port 131 is opposite to and connected to the mounting cavity 4. The purification component can be placed in or taken out of the mounting cavity 4 through the mounting port 131. The high-voltage power supply 52 is installed in the mounting groove 132. The panel 14 is installed on the front side of the face frame 13 and the front side of the face frame 13 can be opened by movement. By forming a mounting groove 132 on the front side of the face frame 13 and installing the high-voltage power supply 52 in the mounting groove 132, the high-voltage power supply 52 can be stably installed in the casing 1, reducing or avoiding unnecessary movement of the high-voltage power supply 52; in addition, the mounting groove 132 is formed on the front side of the face frame 13, which makes the installation and disassembly operations of the high-voltage power supply 52 more convenient, and facilitates related wiring operations on the high-voltage power supply 52 from the front side of the face frame 13, such as facilitating wiring operations between the high-voltage power supply 52 and the electrical control box, the high-voltage power supply 52 and the negative ion generator, etc.

[0079] Referring to Figures 1 to 5, according to some optional embodiments of the present application, the mounting groove 132 is located on the right side of the mounting port 131, and the mounting groove 132 is located on the right side of the mounting cavity 4. By making the mounting groove 132 located on the right side of the mounting port 131 and the mounting cavity 4, the high-voltage power supply 52 is installed in the mounting groove 132, and the high-voltage power supply 52 is located on the right side of the mounting cavity 4 and the mounting port 131.

[0080] Referring to Figures 4 and 5 , according to some optional embodiments of the present application, the high-voltage power supply 52 is removably mounted in the mounting slot 132 in the front-to-back direction. Specifically, the high-voltage power supply 52 can be installed in the mounting slot 132 from the front to the back on the front side of the face frame 13; the high-voltage power supply 52 can be removed from the mounting slot 132 from the back to the front. This arrangement facilitates inspection and maintenance of the high-voltage power supply 52.

[0081] For example, the purification device can be installed in the casing 1 through the following process: first, the high-voltage power supply 52 needs to be positioned with reference to the installation groove 132 of the surface frame 13, and the high-voltage power supply 52 is installed in the installation groove 132; then, the high-voltage power supply 52 can be electrically connected to the electrical control box through the input wiring harness, and the high-voltage power supply 52 can be electrically connected to the negative ion generator, etc. through the wiring harness; then, the purification module 511 of the purification component is placed in the installation cavity 4 along the front-to-back direction, and an electrical connection is formed between the power connection part of the purification module 511 and the output contact 521 of the high-voltage power supply 52; finally, the filter net of the purification component is inserted into the guide limit groove 5111 of the purification module 511 along the front-to-back direction.

[0082] With reference to Figures 12-13, according to some optional embodiments of the present application, the high-voltage power supply 52 includes a switch element 523 for controlling the on / off state of the high-voltage power supply 52. ​​When the panel 14 closes the front side of the face frame 13, the switch element 523 is in a closed state, and the power supply circuit between the high-voltage power supply 52 and the purification module 511 is in a conductive state. When the panel 14 opens the front side of the face frame 13, the switch element 523 is in an open state, and the power supply circuit between the high-voltage power supply 52 and the purification module 511 is in a disconnected state. By providing the switch element 523 for controlling the on / off state of the high-voltage power supply 52, control over the on / off state of the power supply circuit of the high-voltage power supply 52 can be conveniently achieved. Furthermore, when the panel 14 opens the front side of the face frame 13, the high-voltage power supply 52 is in a disconnected state, providing a power-off protection function to prevent accidental harm to the human body caused by the high-voltage power supply 52.

[0083] Referring to Figures 12-13 , according to some optional embodiments of the present application, switch 523 is a trigger-type switch, which is triggered by panel 14; when panel 14 closes the front side of face frame 13, panel 14 triggers switch 523 to switch to the closed state. Trigger-type switches are highly reliable and operate flexibly, accurately completing the task of controlling the power supply circuits of high-voltage power supply 52 and purification module 511. Switching between the closed and open states of switch 523 is achieved by simply opening and closing panel 14, eliminating the need for other auxiliary operations. Therefore, switch 523 is simple to control and easy to operate.

[0084] Referring to Figures 12-13 , according to some optional embodiments of the present application, a trigger protrusion 141 is provided on the rear side of the panel 14. When the panel 14 closes the front side of the face frame 13, the trigger protrusion 141 triggers the switch member 523 to switch to the closed state. When the panel 14 closes the front side of the face frame 13, the trigger protrusion 141 presses against the switch member 523, causing the switch member 523 to switch to the closed state. When the panel 14 opens the front side of the face frame 13, the trigger protrusion 141 moves with the panel 14 to remove the pressure on the switch member 523, causing the switch member 523 to switch to the open state. By providing the trigger protrusion 141 on the rear side of the panel 14, the trigger protrusion 141 can accurately trigger the switch member 523 to switch to the closed state when the panel 14 closes the front side of the face frame 13. The trigger protrusion 141 has a simple structure and is easy to form.

[0085] 12-13 , according to some optional embodiments of the present application, the high-voltage power supply 52 includes a power supply housing 524, a switch member 523 is disposed within the power supply housing 524, and a relief hole 5241 is formed in the power supply housing 524. A trigger spring 5242 is disposed within the relief hole 5241. When the panel 14 closes the front side of the face frame 13, the trigger protrusion 141 presses the trigger spring 5242 backward, deforming it so that the trigger spring 5242 contacts the switch member 523, triggering the switch member 523 to switch to the closed state. When the panel 14 opens the front side of the face frame 13, the trigger spring 5242 disengages from the switch member 523, causing the trigger switch to switch to the open state.

[0086] By setting an avoidance hole 5241 and setting a trigger spring piece 5242 in the avoidance hole 5241, the avoidance hole 5241 is used to avoid the trigger protrusion 141, so that the trigger protrusion 141 can easily contact and trigger the switch component 523. When the panel 14 closes the front side of the face frame 13, the trigger protrusion 141 moves with the panel 14, and the trigger protrusion 141 contacts the trigger spring piece 5242 and transmits external force to the trigger spring piece 5242, so that the trigger spring piece 5242 is deformed and can accurately and stably trigger the switch component 523.

[0087] With reference to Figures 6-8 and 12-13, according to some optional embodiments of the present application, the panel 14 includes a panel body 14 and a panel bracket 14. The panel bracket 14 is detachably connected to the rear side of the panel body 14, and a trigger protrusion 141 is formed on the panel bracket 14, which protrudes rearward. By providing the panel bracket 14, the panel bracket 14 supports the panel body 14, which helps to improve the strength of the panel 14. The rearward-protruding trigger protrusion 141 formed on the panel bracket 14 facilitates the panel 14 to accurately trigger the switch 523 of the high-voltage power supply 52 via the trigger protrusion 141 when the panel 14 is closed against the front side of the face frame 13.
