[0061] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as limiting the present application.

[0062] An air conditioner according to an embodiment of the present application is described below with reference to the drawings.

[0063] like Figures 1-8 As shown, an air conditioner according to an embodiment of the present invention includes: a housing 10 and an air handling unit 20. An air outlet cavity 104 may be provided inside the housing 10. A first air outlet 105 communicating with the outside is formed on the side wall of the air outlet cavity 104, for example, the first air outlet 105 is formed on the front side wall of the air outlet cavity 104. A portion of the housing 10 constitutes the side wall of the air outlet cavity 104. Here, when the air conditioner is placed in an indoor space for operation, the outside refers to the indoor space.

[0064] The air handling unit 20 can be housed inside the casing 10. The air handling unit 20 may include an air handling unit 4. The air handling unit 20 may have an air inlet 411 and a first air outlet 2211. When the air handling unit 20 is working, the air entering the air handling unit 20 through the air inlet 411 can be processed by the air handling unit 4. After passing through the air handling unit 20, the air flows into the air outlet cavity 104 through the first air outlet 2211 of the air handling unit 20. The airflow in the air outlet cavity 104 is blown out into the room through the first air outlet 105, thereby improving the indoor air quality.

[0065] Optionally, when the air handling unit 20 is operating, airflow enters the air handling unit 4 through the air inlet 411, and the airflow can be humidified, purified, etc. by the air handling unit 4. If the air inlet 411 is connected to the indoor air, the air handling unit 4 processes the indoor air before it flows into the room, improving the indoor air quality; if the air inlet 411 is connected to the outdoor air, the air handling unit 4 processes the introduced outdoor air before it flows into the room, thus processing the fresh air while introducing it, further improving the indoor air quality.

[0066] Optionally, the air conditioner may further include an air guide mechanism 60 for opening and closing the first air outlet 2211. The air guide mechanism 60 is movably disposed within the housing 10 along the axial direction of the first air outlet 2211. When the air guide mechanism 60 opens the first air outlet 2211, the first air outlet 2211 is connected to the first air outlet 105 through the air outlet cavity 104; when the air guide mechanism 60 closes the first air outlet 2211, the first air outlet 2211 is isolated from the first air outlet 105. Through the movable air guide mechanism 60 disposed within the housing 10, the connection and isolation between the first air outlet 2211 and the first air outlet 105 of the air handling unit 20 can be achieved by moving the air guide mechanism 60. Therefore, the airflow from the first air outlet 105 can be controlled by controlling the movement of the air guide mechanism 60.

[0067] The outer peripheral side of the first air outlet 2211 can be provided with a light-emitting component 3, which can extend along the circumference of the first air outlet 2211, for example, the light-emitting component 3 can be arc-shaped or ring-shaped. The light-emitting component 3 can be arranged adjacent to the first air outlet 2211. When the light-emitting component 3 emits light, the boundary position of the first air outlet 2211 can be seen from the outside, which facilitates the user to more intuitively see the position of the first air outlet 2211. When the light-emitting component 3 is working, the light-emitting component 3 is adapted to emit light towards the air outlet cavity 104, and the user can see the light emitted by the light-emitting component 3 towards the air outlet cavity 104 from the first air outlet 105. By seeing the light in the air outlet cavity 104, the user can more intuitively obtain the state of the air treatment device 20, improve the convenience of using the air conditioner, and meet the higher needs of the user.

[0068] For example, when the air treatment device 20 is working, the light-emitting component 3 can be controlled to be turned on, and the light emitted by the light-emitting component 3 is emitted towards the air outlet cavity 104. In this way, the user can see the light in the air outlet cavity 104 through the first air outlet 105, so as to more conveniently and intuitively obtain that the air treatment device 20 is currently in a working state. When the air treatment device 20 is not working, the light-emitting component 3 can be controlled to stop working, so that there is no longer light emitted by the light-emitting component 3 towards the air outlet cavity 104 in the air outlet cavity 104. The user can also conveniently and intuitively obtain that the air treatment device 20 is currently in a non-working state. By controlling whether the light-emitting component 3 is turned on according to whether the air treatment device 20 is working, the user can quickly and intuitively understand whether the air treatment device 20 is currently in a working state.

[0069] Further, when the air treatment device 20 is in a working state, the indoor air quality can also be understood through the light-emitting color of the light-emitting component 3. For example, the air conditioner can include an air quality detection device for detecting the indoor air quality. The air quality detection device can detect the carbon dioxide content, formaldehyde content, PM2.5 content, etc. in the room. The air quality detection device can communicate with the light-emitting component 3, and the light-emitting component 3 can adjust the light-emitting color according to the detection result of the air quality detection device. When the indoor air quality is different, the light-emitting component 3 can emit light of different colors. For example, the indoor air quality result detected by the air quality detection device can be divided into poor, medium and good. When the indoor air quality result is poor, the light-emitting component 3 emits red light; when the indoor air quality result is medium, the light-emitting component 3 emits yellow light; and when the indoor air quality result is good, the light-emitting component 3 emits green light. In this way, the user can quickly and intuitively understand the current indoor air quality from the light-emitting color of the light-emitting component 3, so as to make the use of the air conditioner more convenient, improve the user experience, and meet the higher needs of the user.

[0070] The air conditioner of the present application can comprise an air heat exchange device 80, and the air treatment device 20 can be located on one side of the air heat exchange device 80, for example, the air treatment device 20 is located on the upper side or lower side of the air heat exchange device 80, and the air heat exchange device 80 can exchange air with the air heat exchange device 80, so as to adjust the indoor environment temperature.

[0071] Optionally, the air conditioner can be a split type air conditioner, for example, the air conditioner can be a split floor type air conditioner or a split wall type air conditioner; the air conditioner can also be a one-piece type air conditioner. When the air conditioner is a split type air conditioner, the air conditioner comprises an air conditioner indoor unit 100 and an air conditioner outdoor unit, wherein the air conditioner indoor unit 100 comprises the above-mentioned air treatment device 20 and air heat exchange device 80.

[0072] According to the air conditioner of the embodiment of the present application, by arranging the air treatment device 20, the indoor air quality can be improved, and by arranging the light emitting component 3 on the outer peripheral side of the first air outlet 2211, when the air treatment device 20 is working, light is emitted by the light emitting component 3 towards the air outlet cavity 104, so that the user can more intuitively see the position of the first air outlet 2211, and the user can more intuitively obtain the state of the air treatment device 20, the convenience of using the air conditioner is improved, and the higher needs of the user are met.

[0073] According to some embodiments of the present application, with reference to Figures 4-11 , the air treatment device 20 can comprise an air treatment unit 4 and an air outlet box body 2 arranged on the air treatment unit 4, the air outlet box body 2 can be arranged above the air treatment unit 4, and an air outlet cavity 201 can be defined in the air outlet box body 2, the air outlet cavity 201 communicates with the inner cavity of the air treatment unit 4, and a first air outlet 2211 can be formed on the air outlet box body 2, the first air outlet 2211 communicates with the air outlet cavity 201. When the air treatment device 20 is working, the first air outlet 2211 can communicate with the first air outlet 105 through the air outlet cavity 104, the air entering the inner cavity of the air treatment unit 4 from the air inlet 411 flows into the air outlet cavity 201 of the air outlet box body 2 after being treated by the air treatment unit 4, and then flows into the air outlet cavity 104 in the cabinet 10 through the first air outlet 2211, and finally blows out to the indoor through the first air outlet 105 on the cabinet 10, so that the indoor air quality can be improved. By arranging the air outlet box body 2, the air treated by the air treatment unit 4 can be guided into the air outlet cavity 104.

[0074] The air outlet box 2 further has a receiving cavity 231 for receiving the light emitting component 3. The light emitting component 3 is received in the receiving cavity 231. The receiving cavity 231 has a light transmitting portion 232 on the side facing the air outlet cavity 104. The light emitting component 3 emits light through the light transmitting portion 232 into the air outlet cavity 104. The light emitting component 3 is received in the receiving cavity 231 formed on the air outlet box 2, which facilitates the installation of the light emitting component 3 and makes the structure compact. The air blown out of the first air outlet 2211 has less influence on the light emitting component 3. For example, when the air blown out of the first air outlet 2211 is humidified air, the humidified air has less influence on the light emitting component 3.

[0075] Optionally, the light transmitting portion 232 can be a light transmitting hole. The light transmitting portion 232 can also be a transparent solid structure.

[0076] According to some optional embodiments of the present application, referring to Figures 1-11 The air conditioner can further include an air guide mechanism 60 movably arranged in the casing 10 along the axial direction of the first air outlet 2211. For example, when the axial direction of the first air outlet 2211 is the vertical direction, the air guide mechanism 60 is movably arranged in the casing 10 along the vertical direction. The air guide mechanism 60 is moved to open and close the first air outlet 2211, thereby facilitating the control of the communication and isolation between the first air outlet 2211 and the first air outlet 105, and the control of the air outlet of the first air outlet 105. The projection of the light transmitting portion 232 on the reference plane is at least partially located in the projection of the air guide mechanism 60 on the reference plane. The reference plane is perpendicular to the axial direction of the first air outlet 2211. For example, when the axial direction of the first air outlet 2211 is the vertical direction, the reference plane is parallel to the horizontal plane. When the air guide mechanism 60 closes the first air outlet 2211, the air guide mechanism 60 covers at least a portion of the light transmitting portion 232, thereby changing the amount of light emitted by the light emitting component 3 into the air outlet cavity 104 through the light transmitting portion 232.

[0077] For example, when the air guide mechanism 60 opens the first air outlet 2211, the air guide mechanism 60 is spaced apart from the light-transmitting portion 232 and does not cover the light-transmitting portion 232, and the light emitted by the light-emitting component 3 is emitted to the air outlet cavity 104 through the entire light-transmitting portion 232, at this time, the amount of light in the air outlet cavity 104 can be seen from the outside, and the brightness is large; when the air guide mechanism 60 closes the first air outlet 2211, the air guide mechanism 60 covers at least part of the light-transmitting portion 232, when part of the light-transmitting portion 232 is covered by the air guide mechanism 60, the light emitted by the light-emitting component 3 is emitted to the air outlet cavity 104 from the part of the light-transmitting portion 232 that is not covered, and when the light-transmitting portion 232 is completely covered by the air guide mechanism 60, the light emitted by the light-emitting component 3 can be emitted to the air outlet cavity 104 from the gap between the light-emitting component 3 and the air outlet body 2 after passing through the light-transmitting portion 232. Compared with the air guide mechanism 60 opening the first air outlet 2211, when the air guide mechanism 60 closes the first air outlet 2211, the amount of light emitted by the light-emitting component 3 to the air outlet cavity 104 is significantly reduced under the same light-emitting amount of the light-emitting component 3. In this way, the user can conveniently and more intuitively understand whether the air guide mechanism 60 opens the first air outlet 2211 and whether the first air outlet 105 normally blows air by observing the amount of light or the brightness in the air outlet cavity 104.

[0078] According to some optional embodiments of the present application, referring to Figures 6-8 , at least one second air outlet 211 is formed on the circumferential side wall of the air outlet body 2, for example, two second air outlets 211 are formed on the circumferential side wall of the air outlet body 2, and the two second air outlets 211 can be located on opposite sides of the air outlet body 2. A second air outlet 106 is formed on the casing 10 opposite and in communication with the second air outlet 211, the number of second air outlets 106 can be the same as the number of second air outlets 211 and correspond one by one, at least part of the air flow flowing into the air outlet body 2 can be discharged from the second air outlet 211 and blown out to the room through the second air outlet 106. After the air entering the inner cavity of the air treatment unit 4 from the air inlet 411 is treated by the air treatment unit 4, it can be discharged from at least one of the first air outlet 2211 and the second air outlet 211 flowing into the air outlet cavity 201 of the air outlet body 2, thereby enriching the air outlet effect of the air treatment device 20, increasing the air outlet amount of the air treatment device 20, and improving the efficiency of the air treatment device 20 in adjusting the indoor air quality.

[0079] Optionally, a grille can be provided at the second air outlet 211.

[0080] Optionally, the second air outlet 106 can be provided with a damper 16 for opening and closing the second air outlet 106, and the damper 16 is rotatably arranged at the second air outlet 106. The damper 16 can be one or multiple. When the damper 16 is one, the opening and closing of the second air outlet 106 can be realized by rotating the damper 16; when the damper 16 is multiple, the opening and closing of the second air outlet 106 can be realized by rotating the multiple dampers 16. By arranging the rotatable damper 16 at the second air outlet 106, the opening and closing of the second air outlet 106 can be conveniently controlled, so that the air outlet of the second air outlet 106 can be conveniently controlled.

[0081] It should be noted that the "multiple" in the present application refers to two or more than two.

[0082] Optionally, the control of the damper 16 and the air guiding mechanism 60 can be independent of each other, so that the air outlet control of the first air outlet 105 and the second air outlet 106 can be independent of each other, so that the air outlet of the air treatment device 20 can be further diversified.

[0083] For example, when the air guiding mechanism 60 opens the first air outlet 2211 and the damper 16 closes the second air outlet 211, the airflow entering the inner cavity of the air treatment unit 4 from the air inlet 411 flows into the air outlet cavity 201 in the air outlet box 2 after being treated by the air treatment unit 4, and then flows into the air outlet cavity 104 through the first air outlet 2211, and finally blows out to the room through the first air outlet 105. When the air guiding mechanism 60 closes the first air outlet 2211 and the damper 16 opens the second air outlet 211, the airflow entering the inner cavity of the air treatment unit 4 from the air inlet 411 flows into the air outlet cavity 201 in the air outlet box 2 after being treated by the air treatment unit 4, and then flows into the air outlet cavity 104 through the first air outlet 2211, and finally blows out to the room through the first air outlet 105. When the air guiding mechanism 60 opens the first air outlet 2211 and the damper 16 opens the second air outlet 211, the airflow entering the inner cavity of the air treatment unit 4 from the air inlet 411 flows into the air outlet cavity 201 in the air outlet box 2 after being treated by the air treatment unit 4. Part of the airflow flowing into the air outlet cavity 201 flows into the air outlet cavity 104 through the first air outlet 2211, and finally blows out to the room through the first air outlet 105; the other part flows out to the room through the second air outlet 211 and the second air outlet 106 in turn, so that the air outlet volume can be increased, and the air quality adjustment efficiency of the air treatment device 20 can be improved.

[0084] In some optional embodiments of the present application, with reference to Figure 5 、 Figures 9-12, the projection of the light-transmitting portion 232 on the reference plane can be located within the projection of the air guiding mechanism 60 on the reference plane, when the air guiding mechanism 60 closes the first air outlet 2211, the air guiding mechanism 60 completely covers the light-transmitting portion 232, and a light-transmitting channel can be defined between the air guiding mechanism 60 and the air outlet housing 2, a radially inner end of the light-transmitting channel can be opposite to the light-transmitting portion 232, and a radially outer end of the light-transmitting channel can be formed as a light outlet 233. When the air guiding mechanism 60 closes the first air outlet 2211, the light emitted by the light-emitting component 3 enters the light-transmitting channel through the light-transmitting portion 232, then propagates along the light-transmitting channel in a radial direction, and finally exits the light-transmitting channel from the light outlet 233 into the air outlet cavity 104.

[0085] In this way, when the air treatment device 20 is working, when the air guiding mechanism 60 closes the first air outlet 2211, the light emitted by the light-emitting component 3 can still propagate into the air outlet cavity 104 through the light-transmitting channel although the air guiding mechanism 60 completely covers the light-transmitting portion 232, so that the user can still see the light emitted by the light-emitting component 3 from the air outlet cavity 104, thereby enabling the user to directly obtain information that the air treatment device 20 is currently in a working state. Moreover, since the amount of light emitted by the light-emitting component 3 into the air outlet cavity 104 is significantly reduced when the air guiding mechanism 60 closes the first air outlet 2211 relative to when the air guiding mechanism 60 opens the first air outlet 2211, the user can not only obtain information that the air treatment device 20 is currently in a working state, but also obtain information that the first air outlet 105 is currently closed by the air guiding mechanism 60 and the first air outlet 105 stops air outlet.

[0086] According to some optional embodiments of the present application, referring to Figure 5 , Figures 9-12 , the accommodating cavity 231 extends along the circumference of the first air outlet 2211, the light-emitting component 3 can have a shape that is adapted to the shape of the accommodating cavity 231, the light-emitting component 3 extends along the circumference of the first air outlet 2211, and the light-transmitting portion 232 can also extend along the circumference of the first air outlet 2211, and the circumferential extension length of the light-transmitting portion 232 can be substantially consistent with the circumferential extension length of the light-emitting component 3, so that light emitted by different position portions of the light-emitting component 3 can be directly emitted into the air outlet cavity 104 through the opposite portions of the light-transmitting portion 232. The radial width of the light-transmitting portion 232 can be smaller than the radial width of the light-emitting component 3. In this way, the light emitted by the light-emitting component 3 is emitted into the air outlet cavity 104 through the relatively narrow light-transmitting portion 232, so that the light emitted by the light-transmitting portion 232 is more concentrated and has higher brightness, and the user can more conveniently directly see the boundary position of the first air outlet 2211, and this arrangement also enables the light-emitting component 3 to have an elongated strip-shaped light-emitting effect and have a more beautiful appearance.

[0087] According to some optional embodiments of the present application, referring to Figure 5 ,Figures 9-12 The light-transmitting part 232 can be arranged adjacent to the outer periphery of the first air outlet 2211, so that the light-transmitting part 232 can better indicate the position of the first air outlet 2211. For example, the light-transmitting part 232 can be annular, and the annular light-transmitting part 232 can constitute the peripheral edge of the first air outlet 2211. Thus, when the light-emitting component 3 is working, the entire peripheral edge position of the first air outlet 2211 can be conveniently and more intuitively obtained by seeing the annular light ring presented in the air outlet cavity 104, and the appearance is more beautiful.

[0088] Optionally, the light-emitting component 3 can be annular and extend along the circumference of the first air outlet 2211, the accommodating cavity 231 can also be annular and extend along the circumference of the first air outlet 2211, the light-emitting component 3 is mounted to the accommodating cavity 231 along the circumference of the accommodating cavity 231, and the light-transmitting part 232 can also be annular and extend along the circumference of the first air outlet 2211, and the annular light-transmitting part 232 can constitute the peripheral edge of the first air outlet 2211. Thus, the light-transmitting part 232 is more uniform along the circumference of the light-transmitting part 232, and the annular light ring presented in the air outlet cavity 104 can conveniently and more intuitively obtain the entire peripheral edge position of the first air outlet 2211, and the appearance is more beautiful.

The fixing support 23 can be annular and arranged around the air outlet piece 22. The fixing support 23 is connected with the box body 21, and the fixing support 23 facilitates the connection between the air outlet piece 22 and the box body 21. The fixing support 23 and the air outlet piece 22 can jointly define an accommodating cavity 231. The fixing support 23 and the air outlet piece 22 jointly define the accommodating cavity 231, which facilitates the formation of the accommodating cavity 231 and the installation of the light-emitting component 3.

[0090] In some optional embodiments of the present application, referring to Figures 5-12The accommodating groove 2212 can be formed on the air outlet piece 22 at the outer circumferential side of the first air outlet 2211, the light emitting component 3 is arranged in the accommodating groove 2212, the accommodating groove 2212 can extend along the circumference of the first air outlet 2211, for example, the accommodating groove 2212 can be annular and extend along the circumference of the first air outlet 2211. The side of the accommodating groove 2212 facing the air outlet cavity 104 is open to form an open port, the fixing support 23 can cover a part of the open port in the radial direction of the first air outlet 2211, and the inner wall of the accommodating groove 2212 and the fixing support 23 can define an accommodating cavity 231, and the part of the open port that is not covered can constitute a light transmission part 232. This arrangement can facilitate the installation of the light emitting component 3, for example, the light emitting component 3 can be installed in the accommodating groove 2212 before the fixing support 23 is installed on the air outlet piece 22. By making the part of the open port of the accommodating groove 2212 that is not covered by the fixing support 23 constitute the light transmission part 232, the formation of the light transmission part 232 is facilitated, and at this time the light transmission part 232 is formed as a light transmission hole. The width of the light transmission part 232 in the radial direction of the first air outlet 2211 can be less than the width of the open port of the accommodating groove 2212 in the radial direction of the first air outlet 2211, so that the light emitted by the light emitting component 3 through the light transmission part 232 is more concentrated, narrow-gap light emission is achieved, and the user can more easily see and the appearance is more aesthetically pleasing.

For example, the accommodating groove 2212 is formed on the air outlet piece 22 of the air outlet box 2 at the outer circumferential side of the first air outlet 2211, and when the light emitting component 3 is arranged in the accommodating groove 2212, the inner wall of the accommodating groove 2212 can be formed with the first buckle hole 2213. When the light emitting component 3 is installed in the accommodating cavity 231 or the accommodating groove 2212, the installation and fixation of the light emitting component 3 can be facilitated by inserting the first buckle 314 on the light emitting component 3 into the first buckle hole 2213, and the light emitting component 3 can be easily removed from the accommodating cavity 231, facilitating replacement and maintenance of the light emitting component 3, etc.

[0092] In some optional embodiments of the present application, referring to Figure 9 、 Figure 10 、 Figures 21-24The positioning protrusion 315 is formed on the side of the light emitting component 3 away from the light transmitting portion 232, and the positioning hole 2214 is formed on the wall of the accommodating cavity 231. When the light emitting component 3 is installed into the accommodating cavity 231 or the accommodating groove 2212, the positioning protrusion 315 on the light emitting component 3 is inserted into the positioning hole 2214, so that the light emitting component 3 is preliminarily positioned in the accommodating cavity 231, which indicates that the installation position of the light emitting component 3 is accurate, and the first clamping portion 314 is clamped into the first clamping hole 2213, so that the light emitting component 3 can be accurately and reliably installed and fixed in the accommodating cavity 231.

[0093] According to some embodiments of the present application, referring to Figures 21-24 The light emitting component 3 can include a lamp holder 31, a light emitting element 33 and a lamp cover 32.

Specifically, when the air guide mechanism 60 moves upward to a first set position, the air guide mechanism 60 opens the first air outlet 2211, and at this time, part of the air guide mechanism 60 can be accommodated in the air outlet cavity 104; when the air guide mechanism 60 moves downward to a second set position, the air guide mechanism 60 closes the first air outlet 2211.

[0116] The air guide mechanism 60 includes an air guide mechanism body 6a, a lining plate 6b and a decorative cover 6c. The lining plate 6b is arranged between the air guide mechanism body 6a and the decorative cover 6c, specifically, the lining plate 6b is arranged at the top of the air guide mechanism body 6a, and the decorative cover 6c covers the upper surface of the lining plate 6b. The lining plate 6b is detachably connected to the air guide mechanism body 6a, and the decorative cover 6c is connected to the lining plate 6b through an adhesive layer.

The abutting line between the first air guide portion 611 and the second air guide portion 621 is arranged around the first air guide portion 611, the length of the abutting line between the first air guide portion 611 and the second air guide portion 621 is greater than half of the circumference of the first air guide portion 611, the abutting line between the first air guide portion 611 and the second air guide portion 621 extends downwardly in the front-rear direction, and the abutting line between the first moving portion 612 and the second moving portion 622 extends in the up-down direction.

[0118] The spacer plate 6b is formed with limiting holes 63b and first fixing holes 62b, the limiting holes 63b are two and arranged adjacent to the rear side of the spacer plate 6b, the first fixing holes 62b are four and arranged adjacent to the four corner portions of the spacer plate 6b respectively, and the limiting holes 63b and the first fixing holes 62b are formed in the portion of the spacer plate 6b which is not formed with the convex 61b. The air guide mechanism body 6a is formed with second fixing holes 6112 corresponding to the first fixing holes 62b and limiting protrusions 6111 cooperating with the limiting holes 63b, the limiting protrusions 6111 are formed on the first air guide portion 611, and the limiting protrusions 6111 are four, two of which are arranged adjacent to the rear side of the first air guide portion 611 and spaced apart in the left-right direction, and the other two of which are arranged adjacent to the front side of the first air guide portion 611 and spaced apart in the left-right direction. The second fixing holes 6112 are four, two of which are formed on the first air guide portion 611 and arranged adjacent to the front side corner portion of the first air guide portion 611, and the other two of which are formed on the second air guide portion 621 and arranged adjacent to the rear side corner portion of the second air guide portion 621.

[0119] When the spacer plate 6b is connected with the air guide mechanism body 6a, the first fixing holes 62b on the spacer plate 6b and the second fixing holes 6112 on the air guide mechanism body 6a can be corresponded, and at the same time, the limiting protrusions 6111 on the air guide mechanism body 6a can be inserted into the limiting holes 63b on the spacer plate 6b, so that the assembly between the spacer plate 6b and the air guide mechanism body 6a can be preliminarily positioned, and then the first fasteners such as screws are arranged in the first fixing holes 62b and the second fixing holes 6112, so that the spacer plate 6b and the air guide mechanism body 6a can be reliably connected.

[0120] The first air flow channel 610 is formed in the first air guide part 611 and has both front and rear ends open. The second air flow channel 620 is formed in the second air guide part 621 and has both front and rear ends open. The first air guide part 611 has four third clamping holes 6113 formed near the four corners of the first air guide part 611. The second air guide part 621 has four third clamping holes 6211 formed near the four corners of the second air guide part 621.

[0121] When the air guide mechanism 60 opens the first air outlet 2211, the decorative cover 6c, the first air guide part 611, the second air guide part 621, a part of the first moving part 612 and a part of the second moving part 622 are located in the air outlet cavity 104. The first air guide part 61 and the second air guide part 62 are butted along the front-rear direction. The rear side of the first air flow channel 610 and the front side of the second air flow channel 620 are butted and communicated. When the first air guide part 61 and the second air guide part 62 are connected and assembled into the air guide mechanism body 6a, the first air flow channel 610 in the first air guide part 61 and the second air flow channel 620 in the second air guide part 62 are communicated and jointly form a total air flow channel which penetrates the air guide mechanism body 6a along the front-rear direction. Thus, the air flow entering the air outlet cavity 104 from the first air outlet 2211 of the air treatment device 20 can flow to the first air outlet 105 through the space between the air guide mechanism 60 and the inner wall of the air outlet cavity 104, and can flow to the first air outlet 105 through the air flow channel on the air guide mechanism 60 (in turn through the second air flow channel 620 and the first air flow channel 610). Thus, the resistance of the air flow entering the air outlet cavity 104 to the first air outlet 105 can be reduced, the air outlet can be smoother, and the overall air outlet of the first air outlet 105 can be more uniform.

[0122] The driving assembly 70 comprises a driving mechanism 71 and a driving part 72, the driving part 72 comprises a rack 721 and is arranged on the side of the second moving part 622 away from the first moving part 612, and the left and right sides of the driving part 72 are respectively provided with guide ribs 723 extending in the up-down direction. The first moving part 612 is formed with two third fixing holes 6121 arranged in the up-down direction, the second moving part 622 is formed with two fourth fixing holes 6221 arranged in the up-down direction, and the driving part 72 is formed with two fifth fixing holes 722 arranged in the up-down direction. The second fastener is arranged in the fifth fixing hole 722, the fourth fixing hole 6221 and the third fixing hole 6121. When assembling the first air guide 61, the second air guide 62 and the driving part 72, the third buckle 6211 is clamped into the third buckle hole 6113, so that the first air guide part 611 of the first air guide 61 is connected with the second air guide part 621 of the second air guide 62, so that the first air flow channel 610 in the first air guide part 611 and the second air flow channel 620 in the second air guide part 621 are connected and form an air flow channel extending in the front-back direction, and the front and back sides of the air flow channel are open. The second fastener is arranged in the fifth fixing hole 722 of the driving part 72, the fourth fixing hole 6221 of the second moving part 622 and the third fixing hole 6121 of the first moving part 612, so that the driving part 72 is installed on the second moving part 622, and the first moving part 612 and the second moving part 622 are connected, reducing the assembly process and improving the assembly efficiency.

[0123] The driving mechanism 71 comprises a gear transmission mechanism 712 and a driving motor 711, the gear transmission mechanism 712 comprises three gears 7121 engaged in sequence, the gear 7121 at the beginning of the gear transmission mechanism 712 is connected with the driving motor 711, and the gear 7121 at the end of the gear transmission mechanism 712 is engaged with the rack 721. The driving assembly 70 further comprises a driving box 73, the driving mechanism 71 is arranged in the driving box 73, the gear transmission mechanism 712 and the driving motor 711 are arranged in the driving box 73, the driving box 73 is formed with an avoiding opening 733, part of the gear 7121 at the end of the gear transmission mechanism 712 extends out of the driving box 73 through the avoiding opening 733 and is engaged with the rack 721. The driving box 73 defines a first cavity 731 and a second cavity 732, the driving motor 711 and the gear 7121 at the beginning of the gear transmission mechanism 712 are arranged in the first cavity 731, and the remaining two gears 7121 in the gear transmission mechanism 712 are arranged in the second cavity 732, wherein the avoiding opening 733 is formed on the side wall of the second cavity 732, and the first cavity 731 is located outside the air duct.

[0124] The part of the driving box 73 defining the first cavity 731 can be located outside the air outlet box 2, so that the driving motor 711 is located outside the air outlet cavity 201, i.e. outside the air duct of the air treatment device 20, avoiding the influence of the airflow in the air treatment device 20 on the driving motor 711, for example, avoiding the influence of the humidified airflow in the air treatment device 20 on the driving motor 711. The part of the driving box 73 defining the second cavity 732 is located inside the air outlet cavity 201, so that the structure is compact, and the other two gears 7121 of the driving mechanism 71 are located inside the air outlet cavity 201, but since the other two gears 7121 of the driving mechanism 71 are installed in the second cavity 732 of the driving box 73, the influence of the airflow in the air outlet cavity 201 on the meshing of the gears 7121 can be well avoided.

[0125] Further, the driving box 73 includes a first box body 734 and a second box body 735 which are detachably connected, so as to facilitate disassembly, maintenance, etc. of the driving mechanism 71.

[0126] When assembling the air guiding mechanism 60 and the air outlet piece 22, the first moving part 612 and the second moving part 622 of the air guiding mechanism body 6a are inserted into the guide cavity 2241 of the guide piece 224 and can move up and down, the guide protrusions 723 on the driving part 72 cooperate with the guide grooves 2242 on the side wall of the guide cavity 2241, and in the process of moving the air guiding mechanism 60 up and down, the first moving part 612 and the second moving part 622 of the air guiding mechanism body 6a move along the guide of the guide cavity 2241, and at the same time move up and down along the guide grooves 2242 through the guide protrusions 723, realizing the guiding effect of moving the air guiding mechanism 60 up and down, so that the air guiding mechanism 60 can stably move in the up and down direction.

[0127] The upper surface of the air outlet part 221 of the air outlet piece 22 is formed with a receiving groove 2212 located at the outer circumferential side of the first air outlet 2211, the receiving groove 2212 extends in the circumferential direction of the first air outlet 2211 in a ring shape, the light emitting component 3 is arranged in the receiving groove 2212, and the light emitting component 3 is in a ring shape and consistent with the extension direction of the receiving groove 2212. The side of the receiving groove 2212 facing the air outlet cavity 104 is open to form an open port, the fixing support 23 covers part of the open port in the radial direction of the first air outlet 2211, the fixing support 23 covers most of the open port in the radial direction of the first air outlet 2211, and the covered part of the open port is away from the first air outlet 2211. The inner wall of the receiving groove 2212 and the fixing support 23 define a receiving cavity 231, and the part of the open port that is not covered constitutes a light transmission part 232, the light transmission part 232 is a light transmission hole, the light transmission part 232 is in a ring shape and constitutes the circumferential edge of the first air outlet 2211. The radial width of the light transmission part 232 is smaller than the radial width of the light emitting component 3, and the radial width of the light transmission part 232 is smaller than the radial width of the open port of the receiving groove 2212.

[0128] The projection of the light transmission part 232 on the reference surface is located in the projection of the air guide mechanism 60 on the reference surface. When the air guide mechanism 60 moves upward to open the first air outlet 2211, the light transmission part 232 is spaced apart from the air guide mechanism 60 in the up-down direction by a certain distance. At this time, the light emitted by the light emitting component 3 passes through the light transmission part 232 and is emitted upward into the air outlet cavity 104, and the amount of light entering the air outlet cavity 104 is relatively large. When the air guide mechanism 60 closes the first air outlet 2211, the air guide mechanism 60 and the air outlet box 2 define a light transmission channel, the radial inner end of the light transmission channel is opposite to the light transmission part 232, and the radial outer end of the light transmission channel is formed as a light outlet 233. The light emitted by the light emitting component 3 enters the light transmission channel through the light transmission part 232 and propagates radially to the light outlet 233 and is emitted from the light outlet 233 to the air outlet cavity 104 in a substantially radial direction. Compared with opening the first air outlet 2211 by the air guide mechanism 60, the light emitting direction of the light emitting component 3 and the amount of light emitted into the air outlet cavity 104 are changed.

[0129] The light emitting component 3 is in a ring shape, for example, the light emitting component 3 can be a quadrilateral ring shape. The light emitting component 3 includes a lamp holder 31, a light emitting piece 33, a lamp cover 32, and a light guide cover 34, the lamp holder 31, the lamp cover 32, and the light guide cover 34 are all in a closed ring shape, the light emitting piece 33 is a light emitting belt, and the light emitting piece 33 is in an open ring shape. The two ends of the opening of the light emitting piece 33 are provided with a wire harness electrically connected with the light emitting piece 33, which is connected with the circuit board in the electric control box assembly of the whole machine to realize power supply to the light emitting piece 33.

[0130] A mounting groove 310 is formed on the lamp holder 31, and the light-emitting element 33 is disposed within the mounting groove 310. The lamp holder 31 is opaque. A radially outwardly extending wire outlet 317 is also provided on the lamp holder 31, through which the wiring harness connecting to the light-emitting element 33 exits. The lamp cover 32 is transparent and covers the open end of the lamp holder 31. At least a portion of the lamp cover 32 is accommodated within the mounting groove 310. A first limiting surface 311 may be formed on the inner peripheral wall of the mounting groove 310, and the light-emitting element 33 is mounted on the side located away from the lamp cover 32 from the first limiting surface 311. A sealing groove 321 for accommodating sealant is formed on the outer peripheral wall of the lamp cover 32, and the sealing groove 321 extends annularly along the circumference of the lamp cover 32. A plurality of pressing protrusions 322 are formed on the side of the lamp cover 32 adjacent to the light-emitting element 33, and the plurality of pressing protrusions 322 are spaced apart along the circumference of the lamp cover 32. When the lamp cover 32 is installed into the lamp holder 31, sealant is filled into the sealing groove 321 of the lamp cover 32. The lamp cover 32 is then installed into the mounting groove 310 of the lamp holder 31. When the lamp cover 32 abuts against the first limiting surface 311 in the mounting groove 310, it indicates that the lamp cover 32 is installed in place. The lamp cover 32 is sealed to the lamp holder 31 through the sealant, and the multiple pressing protrusions 322 on the lamp cover 32 press against the light-emitting element 33, so that the light-emitting element 33 is stably fixed in the mounting groove 310.

[0131] Multiple second latches 316 are formed on the inner peripheral wall of the lamp holder 31. These second latches 316 are arranged at intervals along the circumference of the lamp holder 31. Similarly, multiple second latches 316 are formed on the outer peripheral wall of the lamp holder 31. The light guide hood 34 has multiple second locking holes 341 formed on its inner peripheral wall. These second locking holes 341 can be arranged at intervals along the circumference of the light guide hood 34. The light guide hood 34 also has multiple second locking holes 341 formed on its outer peripheral wall.

[0132] Furthermore, a second limiting surface 312 is formed on the inner peripheral wall of the lamp holder 31, extending in a ring shape along the circumference of the lamp holder 31; a third limiting surface 313 is formed on the outer peripheral wall of the lamp holder 31, extending in a ring shape along the circumference of the lamp holder 31. When the light guide cover 34 is assembled and connected to the lamp holder 31, the inner peripheral wall of the light guide cover 34 abuts against the second limiting surface 312, and the outer peripheral wall of the light guide cover 34 abuts against the third limiting surface 313, indicating that the light guide cover 34 is installed in place, and causing the second latch 316 on the inner peripheral wall of the lamp holder 31 to engage with the second latch hole 341 on the inner peripheral wall of the light guide cover 34, and the second latch 316 on the outer peripheral wall of the lamp holder 31 to engage with the second latch hole 341 on the outer peripheral wall of the light guide cover 34, thereby facilitating the connection between the light guide cover 34 and the lamp holder 31.

[0133] On the side of the lamp holder 31 away from the light guide 34, a plurality of first latches 314 are formed, and the plurality of first latches 314 are spaced apart in the circumferential direction of the lamp holder 31. On the side of the lamp holder 31 away from the light guide 34 (e.g., the bottom surface of the lamp holder 31), two positioning protrusions 315 are also formed, and the two positioning protrusions 315 are spaced apart in the circumferential direction of the lamp holder 31. The positioning protrusions 315 and the first latches 314 are located on the same side of the lamp holder 31, and at least one first latch 314 is provided between the two positioning protrusions 315. The bottom wall of the receiving groove 2212 has a first latch hole 2213 that mates with the first latch 314 and a positioning hole 2214 that mates with the positioning protrusion 315. When the light-emitting component 3 is installed into the receiving groove 2212, the positioning protrusion 315 on the light-emitting component 3 can be inserted into the positioning hole 2214 to initially position the light-emitting component 3 in the receiving groove 2212, indicating that the installation position of the light-emitting component 3 is accurate at this time, and the first buckle 314 is engaged in the first buckle hole 2213, so that the light-emitting component 3 can be accurately and reliably installed and fixed in the receiving groove 2212.

[0134] When the air handling unit 20 is working, the light-emitting component 3 can be turned on, and the light emitted by the light-emitting component 3 can be projected into the air outlet cavity 104 in a roughly circular shape. When the air handling unit 20 is not working, the light-emitting component 3 can be turned off. Thus, the user can intuitively and conveniently understand whether the air handling unit 20 is in working condition by observing whether there is light from the light-emitting component 3 in the air outlet cavity 104. Furthermore, when the air handling unit 20 is working, the light-emitting component 3 emits more light into the air outlet cavity 104 when the air guide mechanism 60 opens the first air outlet 2211 compared to when the air guide mechanism 60 closes the first air outlet 2211, allowing the user to more intuitively determine whether air is being discharged from the first air outlet 105.

[0135] When the air conditioner is working, it can control one of the air handling unit 20 and the air heat exchanger 80 to work, or it can control both the air handling unit 20 and the air heat exchanger 80 to work.

[0136] When only the air heat exchanger 80 is working, the second fan component 81 operates, and indoor air enters the first installation cavity from the heat exchange inlet 101 and exchanges heat with the heat exchanger component 82 before flowing out into the room from the heat exchange outlets 102 on both sides, thereby regulating the indoor temperature.

[0137] The operation of the air handling unit 20 may include the following situations: only one of the three air inlets 411 that is connected to the outside air is open; only one of the three air inlets 411 that is connected to the outside air is open; all three air inlets 411 are open.

[0138] The first scenario: If only one of the three air inlets 411, which is connected to the outside air, is open, the operation of the air handling unit 20 may include the following situations:

[0139] When only the air handling unit 20 is working, the first fan component 41 is working. When only air needs to be discharged from the first air outlet 105, the air guide plate 16 closes the second air outlet 106, and the air guide mechanism 60 opens the first air outlet 2211. At this time, the first air outlet 2211 is connected to the first air outlet 105 through the air intake chamber. The air introduced from the outside is purified by the purification component 43 and flows upward into the air outlet chamber 201 of the air outlet box 2. It does not pass through the humidification component 42 for humidification, and then flows into the air intake chamber from the first air outlet 2211. Finally, it flows out into the room from the first air outlet 105, thereby introducing outdoor air into the room. At this time, it is possible to purify the outdoor air introduced from the air inlet 411 before it flows into the room, thus improving the indoor air quality.

[0140] When only the second air outlet 106 is needed, the air guide plate 16 opens the second air outlet 106, and the air guide mechanism 60 closes the first air outlet 2211. The air introduced from the outside is purified by the purification component 43 and flows upward into the air outlet cavity 201 of the air outlet box 2. Then, after being humidified by the humidification component 42, it is blown into the room through the two second air outlets 211 and the two second air outlets 106 in sequence. The air introduced from the outside no longer flows out from the first air outlet 105, but flows out into the room from the second air outlets 211 on both sides through the second air outlets 106. Thus, outdoor air can be introduced into the room. At this time, the outdoor air introduced from the air inlet 411 can be purified and humidified before flowing into the room, thereby improving the indoor air quality.

[0141] When air needs to be discharged simultaneously from the first air outlet 105 and the second air outlet 106, the air guide mechanism 60 opens the first air outlet 2211, and the air guide plate 16 opens the second air outlet 106. The first fan component 41 drives the airflow to enter the first fan component 41 from the air inlet 411, and then flows upward. After being purified by the purification component 43, the purified airflow flows upward into the air outlet cavity 201. A portion of the airflow in the air outlet cavity 201 does not pass through the humidification component 42 for humidification and passes through the first air outlet 106. Air 211 is blown upwards into the air intake cavity and then out into the room through the first air outlet 105. Another part is humidified by the humidification component 42 and then blown out from the two second air outlets 211 and the second air outlet 106 in sequence. Fresh air introduced from the outside is simultaneously discharged from the first air outlet 105 and the second air outlet 106, increasing the air outlet range and realizing multi-dimensional three-dimensional air outlet. At this time, the outdoor air introduced from the air inlet 411 can be purified, partially humidified and then flow into the room, which can quickly and effectively improve the indoor air quality.

[0142] Optionally, when the air handling unit 20 is operating, the first air outlet 2211 can be in a normally open state. For example, the first air outlet 2211 opens when the first fan component 41 is powered on and closes when the first fan component 41 stops. The second air outlet 106 can be opened depending on whether humidification is needed. The second air outlet 106 can be opened when humidification is needed and closed when humidification is not needed.

[0143] The second scenario: If only one of the three air inlets 411, which is connected to the indoor air, is open, the operation of the air handling unit 20 may include the following situations:

[0144] When only the air handling unit 20 is working, the first fan component 41 is working. When only air needs to be discharged from the first air outlet 105, the air guide plate 16 closes the second air outlet 106, and the air guide mechanism 60 opens the first air outlet 2211. At this time, the first air outlet 2211 is connected to the first air outlet 105 through the air intake chamber. The air introduced from the room is purified by the purification component 43 and flows upward into the air outlet chamber 201 of the air outlet box 2. It does not pass through the humidification component 42 for humidification, and then flows into the air intake chamber from the first air outlet 2211. Finally, it flows out into the room from the first air outlet 105, thereby purifying the indoor air and improving the indoor air quality.

[0145] When only the second air outlet 106 is needed, the air guide plate 16 opens the second air outlet 106, and the air guide mechanism 60 closes the first air outlet 2211. The air introduced from the room is purified by the purification component 43 and flows upward into the air outlet chamber 201 of the air outlet box 2. Then, after being humidified by the humidification component 42, it is blown out into the room through the two second air outlets 211 and the two second air outlets 106 in sequence. The air introduced from the room no longer flows out from the first air outlet 105, but flows out into the room from the second air outlets 211 on both sides through the second air outlets 106. Thus, the indoor air can be purified and humidified, and the indoor air quality can be improved.

[0146] When air needs to be discharged simultaneously from the first air outlet 105 and the second air outlet 106, the air guide mechanism 60 opens the first air outlet 2211, and the air guide plate 16 opens the second air outlet 106. The first fan component 41 drives the airflow to enter the first fan component 41 from the air inlet 411, and then flows upward. After being purified by the purification component 43, the purified airflow flows upward into the air outlet cavity 201. A portion of the airflow in the air outlet cavity 201 does not pass through the humidification component 42 for humidification and passes through the first air outlet. 2211 blows upwards into the air intake cavity and out into the room through the first air outlet 105. Another part is humidified by the humidification component 42 and then blown out from the two second air outlets 211 and the second air outlet 106 in sequence. The air introduced from the room is simultaneously discharged from the first air outlet 105 and the second air outlet 106, increasing the air outlet range and realizing multi-dimensional three-dimensional air outlet. At this time, the indoor air introduced from the air inlet 411 can be purified, partially humidified and then flow into the room, which can quickly and effectively improve the indoor air quality.

[0147] Optionally, when the air handling unit 20 is operating, the first air outlet 2211 can be in a normally open state. For example, the first air outlet 2211 opens when the first fan component 41 is powered on and closes when the first fan component 41 stops. The second air outlet 106 can be opened depending on whether humidification is needed. The second air outlet 106 can be opened when humidification is needed and closed when humidification is not needed.

[0148] The third scenario: When all three air inlets 411 are open, the operation of the air handling unit 20 may include the following situations:

[0149] When only the air handling unit 20 is working, the first fan component 41 is working. When only air needs to be discharged from the first air outlet 105, the air guide plate 16 closes the second air outlet 106, and the air guide mechanism 60 opens the first air outlet 2211. At this time, the first air outlet 2211 is connected to the first air outlet 105 through the air intake chamber. The air introduced from the room and the air introduced from the outside are purified by the purification component 43 and then flow upward into the air outlet chamber 201 of the air outlet box 2. Without being humidified by the humidification component 42, the air flows into the air intake chamber from the first air outlet 2211 and finally flows out into the room from the first air outlet 105. This can purify the indoor air, improve the indoor air quality, and introduce fresh air and purify the introduced fresh air.

[0150] When only the second air outlet 106 is needed, the air guide plate 16 opens the second air outlet 106, and the air guide mechanism 60 closes the first air outlet 2211. The air introduced from the room and the air introduced from the outside are purified by the purification component 43 and flow upward into the air outlet chamber 201 of the air outlet box 2. Then, after being humidified by the humidification component 42, it is blown out into the room through the two second air outlets 211 and the two second air outlets 106 in sequence. The air introduced from the room and the air introduced from the outside no longer flow out from the first air outlet 105, but flow out into the room from the second air outlets 211 on both sides through the second air outlets 106. Thus, the indoor air can be purified and humidified, improving the indoor air quality. Fresh air can also be introduced and purified and humidified.

[0151] When air needs to be discharged simultaneously from the first air outlet 105 and the second air outlet 106, the air guide mechanism 60 opens the first air outlet 2211, and the air guide plate 16 opens the second air outlet 106. The first fan component 41 drives the airflow to enter the first fan component 41 from the air inlet 411, and then flows upward. It is first purified by the purification component 43, and the purified airflow flows upward into the air outlet cavity 201. A portion of the airflow in the air outlet cavity 201 does not pass through the humidification component 42 for humidification and is blown upward through the first air outlet 2211 into the air intake cavity and then through the first air outlet. Air 105 is blown into the room, and another part is humidified by the humidification component 42 and then blown out from the two second air outlets 211 and the second air outlet 106 in sequence. Air introduced from the room and air introduced from the outside are simultaneously blown out from the first air outlet 105 and the second air outlet 106, increasing the air outlet range and realizing multi-dimensional three-dimensional air outlet. At this time, the indoor air introduced from the air inlet 411 can be purified and partially humidified before flowing into the room, which can quickly and effectively improve the indoor air quality. Fresh air can also be introduced and purified and partially humidified.

[0152] Optionally, when the air handling unit 20 is operating, the first air outlet 2211 can be in a normally open state. For example, the first air outlet 2211 opens when the first fan component 41 is powered on and closes when the first fan component 41 stops. The second air outlet 106 can be opened depending on whether humidification is needed. The second air outlet 106 can be opened when humidification is needed and closed when humidification is not needed.

[0153] When both the air handling unit 20 and the air heat exchanger 80 are working, the indoor temperature can be regulated and the indoor air quality can be improved. The working state of the air handling unit 20 can be referred to the above description.
