[0054] Air conditioners typically achieve air heat exchange through a heat exchange device and air purification through a purification device. In existing air conditioners, the purification device and the heat exchange device usually share a common air duct. This means that while the heat exchange device is exchanging heat with the air, the placement of the purification device within the air duct can easily create air resistance for the heat exchange airflow, thereby reducing the air volume output by the air conditioner and lowering the user experience.

[0055] In view of the above, the present invention provides an air conditioner, which includes an indoor unit, wherein the indoor unit can be a wall-mounted indoor unit, a ceiling-mounted indoor unit, or a floor-standing indoor unit. For ease of understanding, the following embodiments will use a wall-mounted indoor unit as an example for illustration. Please refer to... Figures 1 to 10 The attached figure shows a specific embodiment of the air conditioner indoor unit provided by the present invention.

[0056] Please see Figure 1 , Figure 5 and Figure 6The indoor unit of the air conditioner proposed in this invention includes a heat exchange device 100 and a purification device 200. The heat exchange device 100 forms a heat exchange air duct 111 and is used to exchange heat with the air passing through the heat exchange air duct 111 before discharging it. The purification device 200 is installed on the heat exchange device 100 and forms a purification air duct 211. The purification device 200 is used to purify the air passing through the purification air duct 211 before discharging it. The purification air duct 211 and the heat exchange air duct 111 are independently arranged.

[0057] In the technical solution provided by this invention, the heat exchange duct 111 enables air heat exchange, and the purification duct 211 enables air purification. The independent arrangement of the heat exchange duct 111 and the purification duct 211 ensures that the heat exchange function and the purification function of the air conditioner indoor unit are independent and do not affect each other, avoiding mutual interference between air heat exchange and air purification. This helps to reduce the wind resistance generated by the purification device 200 on the heat exchange airflow and ensure the heat exchange air volume. Moreover, users can choose to heat exchange, purify, or perform both heat exchange and purification simultaneously according to their actual needs, which contributes to the functional diversity of the air conditioner indoor unit.

[0058] It is understood that the heat exchange device 100 is used to exchange heat with the air, that is, to heat or cool the air, so as to adjust the indoor temperature to a temperature that makes the user feel comfortable; the purification device 200 is used to purify the air. Specifically, the purification includes sterilizing and disinfecting the indoor environment, reducing dust and haze, removing harmful decoration residues and unpleasant odors, so as to make the indoor air more conducive to the user's health.

[0059] The heat exchange device 100 can be an independent heat exchange equipment or product including a heat exchanger and other structures. After being assembled with the purification device 200, it is packaged in a shell structure to form the indoor unit of the air conditioner. Alternatively, a conventional air conditioner body can directly constitute the heat exchange device 100 described in this embodiment. Based on this, the purification device 200 and the conventional air conditioner body are separately set up, and can be connected to the conventional air conditioner body as needed. In the following embodiments, the conventional air conditioner body is used as an example to illustrate the heat exchange device 100.

[0060] The heat exchange device 100 includes a housing 110 forming the heat exchange duct 111, and the housing 110 is provided with a heat exchange inlet 112 and a heat exchange outlet 113 respectively communicating with the heat exchange duct 111; the purification device 200 includes an outer shell 210 forming the purification duct 211, and the outer shell 210 is provided with a purification inlet 212 and a purification outlet 213 respectively communicating with the purification duct 211.

[0061] The purification device 200 is installed on the heat exchange device 100. Specifically, the purification device 200 can be encapsulated inside the housing 110, making the overall structure of the air conditioner indoor unit compact; or the purification device 200 can be installed outside the housing 110, so that the disassembly and assembly of the purification device 200 does not affect the structural integrity of the heat exchange device 100, making it more convenient to disassemble and replace the purification device 200.

[0062] The purification device 200 and the heat exchange device 100 are connected by a detachable connection structure. The detachable connection structure can take various forms:

[0063] In one embodiment, the detachable connection structure includes a latching part 261 and a latching hole part (not shown in the figures) that interlock with each other. One of the latching part 261 and the latching hole part is disposed on the housing 110, and the other is disposed on the outer casing 210. The specific form of the latching part 261 and the latching hole part is not limited, and they can be designed with different shapes, sizes and materials to correspond to different mounting carriers.

[0064] In one embodiment, the detachable connection structure includes a matching threaded portion (not shown in the drawings) and a threaded hole portion 262. One of the threaded portion and the threaded hole portion 262 is disposed on the housing 110, and the other is disposed on the outer casing 210. It can be understood that the threaded hole portion 262 is a threaded hole formed on the mounting carrier, and the threaded portion can be a bolt or other structure adapted to the threaded hole to achieve threaded fixation between the housing 110 and the outer casing 210; alternatively, the threaded portion can also be another threaded hole adapted to the threaded hole, and the two threaded holes are used to achieve threaded fixation between the housing 110 and the outer casing 210 through an additional bolt or other structure.

[0065] In one embodiment, the detachable connection structure may simultaneously include the aforementioned snap-fit ​​portion 261, snap-fit ​​hole portion, screw connection portion, and screw hole portion 262, thereby achieving a secure installation of the housing 110 and the outer casing 210. The specific features of the snap-fit ​​portion 261, snap-fit ​​hole portion, screw connection portion, and screw hole portion 262 are as described above and will not be repeated here.

[0066] Specifically, please refer to Figure 1 and Figure 4 When the heat exchange device 100 is specifically manifested as a conventional air conditioner body, the housing 110 of the heat exchange device 100 includes a chassis and a face frame. The chassis is provided with a snap-fit ​​portion and the face frame is provided with a screw hole portion 262. The purification device 200 is provided with a snap-fit ​​portion 261 that engages with the snap-fit ​​portion and a screw portion that engages with the screw hole portion 262 at the corresponding position.

[0067] The heat exchange duct 111 and the purification duct 211 are set independently of each other. Furthermore, the heat exchange inlet 112, the heat exchange outlet 113, the purification inlet 212 and the purification outlet 213 are set at intervals to ensure that no duct section of the heat exchange duct 111 and the purification duct 211 is shared, thereby helping to prevent crossflow between the heat exchange airflow in the heat exchange duct 111 and the purification airflow in the purification duct 211.

[0068] Please see Figure 1 , Figure 5 and Figure 6 In one embodiment, the purification device 200 includes a fan assembly 250, which is disposed in the purification duct 211 and is used to introduce air into the purification duct 211 from the purification air inlet 212 and discharge it through the purification air outlet 213.

[0069] The specific form of the fan assembly 250 is not limited; it can be any suitable fan structure, such as a centrifugal fan or an axial fan. The fan assembly 250 can be optionally installed at the purified air outlet 213 so that the air is fully purified in the purified air duct 211 and then directly delivered from the purified air outlet 213.

[0070] To improve the overall compactness of the indoor unit of the air conditioner, the purification duct 211 can be configured to extend in a straight line or bend along the contour surface of the heat exchange device 100. In one embodiment, the purification duct 211 is located below the heat exchange device 100, and the fan assembly 250 is located on one side of the heat exchange device 100. Based on this, the purification air inlet 212 is located below the heat exchange device 100, and the purification air outlet 213 is located on the side of the heat exchange device 100. After the purified airflow flows below the heat exchange device 100, it flows upward along the side of the heat exchange device 100 under the action of the fan assembly 250, and is finally discharged from the purification air outlet 213, which helps to increase the ventilation volume and expand the purification area.

[0071] One of the heat exchange air inlet 112 and the purification air inlet 212 is located at the upper end of the indoor unit of the air conditioner, and the other is located at the lower end of the indoor unit of the air conditioner. Taking the heat exchange air inlet 112 located at the upper end of the indoor unit of the air conditioner and the purification air inlet 212 located at the lower end of the indoor unit of the air conditioner as an example, the vertical arrangement of the heat exchange air inlet 112 and the purification air inlet 212 can fully separate the heat exchange air inlet 112 and the purification air inlet 212, so that the air intake of the heat exchange device 100 and the air intake of the purification device 200 will not interfere with each other.

[0072] Both the heat exchange air outlet 113 and the purification air outlet 213 are arranged facing forward, and they are staggered along the length and vertical direction of the indoor unit. When the indoor unit is mounted on the wall at the back, the front of the unit is exposed to the indoor environment. By setting the openings of both the heat exchange air outlet 113 and the purification air outlet 213 to face forward, the heat-treated air and the purified air are directly introduced into the indoor environment, which helps to improve air handling efficiency.

[0073] The purification air outlet 213 is located adjacent to the heat exchange air inlet 112. That is, the purification air outlet 213 is located around the heat exchange air inlet 112. Under the action of the airflow formed at the heat exchange air inlet 112, the purified airflow in the purification duct 211, after being sent out from the purification air outlet 213, forms a return flow around the heat exchange air inlet 112. The return air enters the heat exchange duct 111 for heat exchange treatment, making the heat exchange airflow sent out through the heat exchange air outlet 113 cleaner and healthier.

[0074] In addition, please see Figures 2 to 3 , Figure 9 In one embodiment, the purification device 200 includes an electronic control component 220 disposed within the purification air duct 211. It is understood that the electronic control component 220 provides power and control signals to components within the purification device 200, such as the fan assembly 250. Disposing of the electronic control component 220 within the purification air duct 211 increases the overall compactness of the purification device 200. Furthermore, since the electronic control component 220 is prone to generating heat during operation, the continuous flow of purified air within the purification air duct 211 under the action of the fan assembly 250 effectively carries away the heat generated by the electronic control component 220, resulting in good cooling of the electronic control component 220. This eliminates the need for additional heat dissipation components, reducing the overall cost of the indoor air conditioning unit while also increasing its operational reliability.

[0075] Further, please refer to Figures 8 to 10 In one embodiment, the purification air duct 211 includes a main air duct 211a and a receiving groove 211b that are interconnected, the receiving groove 211b extending along the airflow direction of the main air duct 211a; the electronic control component 220 is installed in the receiving groove 211b.

[0076] In view of the above, when the main air duct 211a is arranged below the heat exchange device 100 and extends along the length of the heat exchange device 100, the receiving groove 211b is arranged in parallel with at least a part of the air duct section of the main air duct 211a. That is, the receiving groove 211b extends along the airflow direction of the main air duct 211a, so that more parts of the electronic control component 220 housed in the receiving groove 211b can exchange heat with the purified airflow in the main air duct 211a, thereby improving the heat dissipation effect of the electronic control component 220.

[0077] The slot of the receiving groove 211b is formed in the outer shell 210 of the purification device 200, allowing the receiving groove 211b to communicate with the external environment of the purification device 200. After the electronic control component 220 is inserted into the receiving groove 211b through the slot, the electronic control component 220 can be quickly installed in the purification air duct 211. In a further embodiment, the outer shell 210 also includes a cover plate 211c, which is used to cover the slot of the receiving groove 211b after the electronic control component 220 is installed into the receiving groove 211b, thus preventing the electronic control component 220 from coming out of the slot of the receiving groove 211b.

[0078] Please see Figures 2 to 3 In one embodiment, the electronic control assembly 220 includes an electronic control board 221 and an electronic control box 222 mounted on the electronic control board 221. The electronic control box 222 is provided with a through hole 223 at the connection between the main air duct 211a and the receiving groove 211b. The through hole 223 is used to expose the corresponding part of the electronic control board 221 in the main air duct 211a.

[0079] The specific structure of the control board 221 is not detailed in this design. The control box 222 has a mounting slot for mounting the control board 221. There are several ways to install the control board 221 in the control box 222, such as using a snap-fit ​​structure to hold and fix the control board 221, using a limiting structure to limit and abut the control board 221, using a screw-fit structure to screw and fix the control board 221, or using an adhesive structure to adhesive and fix the control board 221, etc.

[0080] The through-hole 223 allows at least a portion of the electronic control board 221 to be directly exposed within the main air duct 211a, enabling direct heat exchange with the purified airflow and reducing energy loss during heat conduction through the connecting wall between the main air duct 211a and the receiving groove 211b. The through-hole 223 can take various forms, such as multiple heat dissipation holes dispersed on the connecting wall, or multiple grid holes arranged in a grid pattern within the connecting wall.

[0081] Similarly, there are multiple ways to install the electrical control box 222 in the receiving slot 211b. For example, in this embodiment, the electrical control box 222 is fixedly installed in the receiving slot 211b by screw fastener 224. After the electrical control component 220 is inserted into the receiving slot 211b, the electrical control box 222 is positioned in a set position in the receiving slot 211b by adapting the size of the receiving slot 211b or by setting a positioning structure in the receiving slot 211b. This facilitates the user to operate the screw fastener 224 from the outside of the air conditioner indoor unit, thus achieving the screw-fixed fixation of the electrical control box 222 in the receiving slot 211b.

[0082] Please see Figures 5 to 7 In one embodiment, the electronic control assembly 220 further includes an electro-purification module 225 disposed at the through hole 223, the electro-purification module 225 being electrically connected to the electronic control board 221. The power supply and control signals for the electro-purification module 225 are provided by the electronic control board 221. Therefore, under the control of the electronic control board 221, the electro-purification module 225 performs secondary sterilization and disinfection on the airflow passing through the main air duct 211a, which helps to further optimize the air purification effect.

[0083] It is understood that there are various specific designs for the electro-purification module 225. Specifically, the electro-purification module 225 may include an ultraviolet (UV) disinfection module and / or a plasma disinfection module. Taking the UV disinfection module as an example, the UV disinfection module is, for instance, a UV lamp. The UV lamp is installed on the side of the control board 221 facing the main air duct 211a, with the light-emitting side of the UV lamp facing the main air duct 211a, for secondary sterilization and disinfection of the purified airflow passing through the main air duct 211a. When the electro-purification module 225 is a plasma disinfection module, the plasma disinfection module utilizes a bipolar plasma electrostatic field to decompose and break down negatively charged bacteria, polarize and adsorb dust, achieving secondary sterilization and filtration of the air. It should be noted that the electro-purification module 225 can be configured as either a UV disinfection module or a plasma disinfection module, or it can be configured as both, to further optimize the air purification effect.

[0084] Next, please refer to Figure 1 , Figure 4 and Figure 9 In one embodiment, the purification device 200 includes a filter assembly 230 disposed in the purification air duct 211, the filter assembly 230 being used to filter the air passing through the purification air duct 211. The filter assembly 230 is used to filter out dust, haze particles, etc. from the air.

[0085] The specific selection of filter components 230 is not limited. For example, formaldehyde removal filters, HEPA (High Efficiency Particulate Air) filters, activated carbon filters, and filter paper filters can be selected.

[0086] The location of the filter assembly 230 within the purification duct 211 is not limited; it can be placed anywhere within the purification duct 211. For example, the filter assembly 230 can be placed at the purification air inlet 212, which facilitates the disassembly and cleaning of the filter assembly 230.

[0087] In one embodiment, multiple filter components 230 are stacked along the airflow direction at their location. It should be noted that a larger number of filter components 230 enables multi-stage air filtration and purification, but also increases air resistance to some extent; conversely, a smaller number of filter components 230 reduces the impact on the airflow volume, but weakens the filtration and purification effect. Therefore, the number of filter components 230 must be set within a reasonable range.

[0088] In one embodiment, the purification device 200 further includes a mounting bracket 240 disposed on the purification air duct 211. The mounting bracket 240 has multiple mounting positions, each of which is used to install one of the filter components 230. The mounting bracket 240 is generally a cylindrical structure adapted to the shape of the purification air inlet 212 to realize the communication between the purification air duct 211 and the indoor environment. The inner wall of the cylindrical structure may be provided with protruding limiting ribs, and multiple limiting ribs are spaced apart along the airflow direction within the cylindrical structure. Each limiting rib is used to define one mounting position, or every two adjacent limiting ribs jointly define one mounting position. Of course, the mounting position can also be defined by other structures disposed on the mounting bracket 240, which is not limited here.

[0089] The multiple installation positions provide sufficient installation space for the filter assembly 230. Users can install the filter assembly 230 in at least one of the multiple installation positions according to their actual needs, thereby achieving user customization of the purification device 200.

[0090] Please see Figure 7In one embodiment, the mounting bracket 240 is disposed at the purification air inlet 212 and has an inner end extending from the purification air inlet 212 into the purification air duct 211 and an outer end extending out of the purification air inlet 212. The inner end is provided with a stop structure 241, which abuts against and limits the outer shell 210 located on the periphery of the purification air inlet 212. The stop structure 241 is an annular stepped structure protruding from the side wall of the mounting bracket 240 and extending along the circumferential direction of the mounting bracket 240, which helps to prevent the mounting bracket 240 and at least one filter assembly 230 mounted on the mounting bracket 240 from detaching from the purification air duct 211.

[0091] In view of the above, the air conditioner includes an indoor unit, and the detailed structure of the indoor unit can be referred to the above-described embodiments of the indoor unit, which will not be repeated here.
