[0057] The following is for reference. Figures 1-22 The air conditioner 100 according to the present invention can buffer the airflow, reduce the backflow air volume, ensure the air volume of the air conditioner 100, reduce the pressure pulsation on the surface of the volute 3, reduce the vibration and noise in the centrifugal air duct 75, improve the user experience, and ensure the comfort of use.

[0058] like Figures 1-22 As shown, an air conditioner 100 according to an embodiment of the present invention includes: a body 1, a volute assembly 7, and a volute tongue 3.

[0059] The main body 1 is provided with an air inlet 112 and an air outlet 122. A centrifugal air duct 75 is formed inside the volute assembly 7. A centrifugal impeller 5 is installed inside the centrifugal air duct 75. The volute assembly 7 is provided with a volute air inlet 73 and a volute air outlet 74, which are respectively connected to the centrifugal air duct 75. A heat exchanger assembly 2 is provided between the volute air inlet 73 and the main body air inlet 112. The volute air outlet 74 is connected to the main body air outlet 122. The volute tongue 3 is made of soft material and is installed at the volute air outlet 74.

[0060] In this context, air conditioner 100 refers to an air conditioning unit, which includes an air conditioning unit and other structures. Air conditioner 100 is a unit used to provide air to a space (generally enclosed) to handle temperature changes. The function of air conditioner 100 is to regulate parameters such as temperature, humidity, cleanliness, and airflow velocity of the air in a room (or enclosed space, area) by generating cool or hot air to meet the requirements of human comfort or process control. In this embodiment, air conditioner 100 may refer to a wall-mounted air conditioner 100.

[0061] Specifically, the air conditioner 100 is provided with a body 1, which is located on the outermost side of the air conditioner 100. The air conditioner 100 can be installed on a wall or other location through the body 1, which facilitates the installation of the air conditioner 100 and ensures the reliability of the air conditioner 100 in use. An installation space can be formed inside the body 1, and the operating parts of the air conditioner 100 can be installed in the installation space and fixedly connected to the body 1, thereby ensuring the reliability of the installation of the parts and ensuring the reliability of the operation of the air conditioner 100.

[0062] The unit 1 is equipped with an air inlet 112 and an air outlet 122. Outside air can enter the unit 1 through the air inlet 112 and undergo heat exchange inside the unit 1 to cool or heat the airflow. The cooled or heated airflow can be delivered to the room through the air outlet 122 to cool or heat the room, thus meeting different user needs.

[0063] Furthermore, the air conditioner 100 is also provided with a volute assembly 7, which is installed inside the body 1 and can be fixed to the body 1 by means of integral molding or connectors. A centrifugal air duct 75 is formed inside the volute assembly 7. The volute assembly 7 also forms a volute air inlet 73 and a volute air outlet 74. Both the volute air inlet 73 and the volute air outlet 74 are connected to the centrifugal air duct 75. A centrifugal impeller 5 is provided inside the centrifugal air duct 75. The centrifugal impeller 5 is rotatable relative to the volute assembly 7. When the centrifugal impeller 5 rotates, the airflow can enter the centrifugal air duct 75 through the volute air inlet 73 and, after being accelerated by the centrifugal impeller 5, can be discharged from the centrifugal air duct 75 through the volute air outlet 74.

[0064] Furthermore, a heat exchanger assembly 2 is provided between the volute air inlet 73 and the body air inlet 112. After the outside airflow enters the body 1 through the body air inlet 112, it can flow through the heat exchanger assembly 2 to exchange heat with the heat exchanger assembly 2, so that the airflow can be heated or cooled. The heated or cooled airflow can enter the centrifugal air duct 75 through the volute air inlet 73 to be accelerated by the centrifugal impeller 5. The volute air outlet 74 is connected to the body air outlet 122, so that the heat-exchanged and accelerated airflow can be delivered to the body air outlet 122 through the volute air outlet 74, and then delivered to the room through the body air outlet 122, thereby heating or cooling the indoor environment.

[0065] When indoor cooling is required, the airflow can exchange heat with the heat exchanger assembly 2 at the heat exchanger assembly 2, so that the airflow becomes low-temperature airflow. The low-temperature airflow enters the centrifugal air duct 75 for acceleration, and then is delivered to the air outlet 122 of the unit through the volute air outlet 74, so as to deliver the airflow into the room to cool the room. When indoor heating is required, the airflow can exchange heat with the heat exchanger assembly 2 at the heat exchanger assembly 2, so that the airflow becomes high-temperature airflow. The high-temperature airflow enters the centrifugal air duct 75 for acceleration, and then is delivered to the air outlet 122 of the unit through the volute air outlet 74, so as to deliver the airflow into the room to heat the room and ensure user comfort.

[0066] In addition, the air conditioner 100 is also equipped with a volute tongue 3, which is installed at the air outlet 74 of the volute. When the airflow flows through the centrifugal air duct 75 to the air outlet 74 of the volute, and then through the air outlet 74 to the air outlet 122 of the unit, the airflow can pass through the volute tongue 3. The volute tongue 3 is made of a soft material, such as foam. The soft material of the volute tongue 3 allows the airflow to be buffered when it impacts the volute tongue 3, reducing the backflow of airflow into the centrifugal air duct 75. This ensures the airflow to the air outlet 122 of the unit, guarantees the air volume of the air conditioner 100, improves the user experience, and reduces the pressure pulsation on the surface of the volute tongue 3, thereby reducing vibration and noise in the centrifugal air duct 75 and ensuring user comfort.

[0067] According to the embodiment of the present utility model, the air conditioner 100 has a soft material volute tongue 3 at the air outlet 74 of the volute. When the airflow flows to the air outlet 74 of the volute, it can be buffered at the volute tongue 3, thereby reducing the backflow of airflow, ensuring the air volume of the air conditioner 100, improving the user experience, and reducing the pressure pulsation on the surface of the volute tongue 3, thereby reducing the vibration and noise in the centrifugal air duct 75, ensuring user comfort, better performance, and wider applicability.

[0068] In some embodiments, the volute assembly 7 is provided with an air guide mounting plate 76, which is located at the volute air outlet 74, and the volute tongue 3 is mounted on the air guide mounting plate 76.

[0069] Specifically, the volute assembly 7 is installed inside the body 1, and as... Figures 1-3As shown, the volute assembly 7 is provided with an air guide mounting plate 76. The air guide mounting plate 76 can be integrally formed with the volute assembly 7, or it can be connected to the volute assembly 7 via connectors, etc. The air guide mounting plate 76 is located at the volute air outlet 74. That is, when the airflow flows through the centrifugal air duct 75 to the volute air outlet 74, it can flow through the air guide mounting plate 76 and then flow to the air outlet 122 of the unit. The volute tongue 3 is installed on the air guide mounting plate 76. The volute tongue 3 can be connected to the air guide mounting plate 76 by means of adhesive, snap-fit, or connectors. The volute tongue 3 is made of soft material, so that the airflow can be buffered at the volute tongue 3 when it flows through the air guide mounting plate 76, reducing airflow backflow, ensuring air volume, and reducing vibration and noise in the centrifugal air duct 75, ensuring user comfort.

[0070] In some embodiments, the volute tongue 3 is detachably connected to the air guide mounting plate 76. The volute assembly 7 is provided with the air guide mounting plate 76, and the volute tongue 3 is mounted on the air guide mounting plate 76, such that the volute tongue 3 is positioned at the volute outlet 74. This allows the airflow from the centrifugal duct 75 to the volute outlet 74 to pass through the volute tongue 3, thereby buffering the airflow. Figure 1 As shown, the volute tongue 3 is detachable from the air guide mounting plate 76. That is, the volute tongue 3 can be connected to the air guide mounting plate 76 by means of snap-fit ​​or connectors, which makes installation convenient and facilitates cleaning and maintenance of the volute tongue 3, saving maintenance time and reducing maintenance costs.

[0071] In some embodiments, the air guide mounting plate 76 is formed with an air guide mounting groove 761, the volute tongue 3 is formed with an air guide boss 31, the volute tongue 3 is mounted on the side of the air guide mounting plate 76 away from the air outlet 74 of the volute, the air guide boss 31 extends into the air guide mounting groove 761, and the air guide boss 31 is formed with a boss air guide surface 311 facing into the air outlet 74 of the volute.

[0072] Specifically, the volute tongue 3 is detachably mounted on the air guide mounting plate 76, facilitating installation and subsequent maintenance, and as... Figures 1-9 As shown, the air guide mounting plate 76 is configured as an air guide mounting groove 761, which extends through the air guide mounting plate 76. The volute tongue 3 has an air guide protrusion 31, which protrudes towards the side of the volute tongue 3. The volute tongue 3 can be installed on the side of the air guide mounting plate 76 away from the volute outlet 74 by means of connectors or snap-fit. The air guide protrusion 31 of the volute tongue 3 can extend from the side of the air guide mounting plate 76 away from the volute outlet 74 into the air guide mounting groove 761, and the air guide protrusion 31 protrudes towards the volute outlet 74.

[0073] Furthermore, such as Figures 5-6As shown, the air guide mounting plate 76 is configured as an arc-shaped plate bent towards the air outlet 74 of the volute, and the volute tongue 3 is also configured as an arc-shaped part. The air guide protrusion 31 is set on the outwardly protruding arc-shaped surface of the volute tongue 3. When the volute tongue 3 is installed on the air guide mounting plate 76, the air guide protrusion 31 can be placed in the air guide mounting groove 761, so that the air guide mounting groove 761 can limit the air guide protrusion 31 and ensure the installation stability of the volute tongue 3. The side of the air guide protrusion 31 facing the air outlet 74 of the volute forms a protruding air guide surface 311. When the airflow passes through the air outlet 74 of the volute, it can impact the protruding air guide surface 311, so that the protruding air guide surface 311 can buffer the airflow and guide the airflow, so that the airflow flows towards the air outlet 122 of the machine body, reducing airflow backflow, and reducing vibration and noise in the centrifugal air duct 75, ensuring user comfort.

[0074] In some embodiments, there are multiple air guide mounting slots 761, which are distributed at intervals along the width direction of the volute air outlet 74, and multiple air guide protrusions 31, which extend to the air guide mounting slots 761 in a one-to-one correspondence.

[0075] Specifically, the air guide mounting plate 76 is provided with an air guide mounting groove 761, and the volute 3 is provided with an air guide boss 31, which can extend into the air guide mounting groove 761, and as... Figures 1-5 As shown, the air guide mounting groove 761 can be configured in multiple ways, such as two, three, or four. In this embodiment, the air guide mounting groove 761 is configured in three ways. The air guide protrusion 31 can also be configured in multiple ways, such as two, three, or four. In this embodiment, the air guide protrusion 31 is configured in three ways. The multiple air guide protrusions 31 are configured in a one-to-one correspondence, so that each air guide protrusion 31 can extend into the corresponding air guide mounting groove 761. This allows the multiple air guide mounting grooves 761 to limit the corresponding air guide protrusion 31, thereby ensuring the installation stability of the volute tongue 3 at multiple locations.

[0076] Furthermore, multiple air guide mounting slots 761 are spaced apart along the width direction of the volute air outlet 74, so that when multiple air guide protrusions 31 extend into the corresponding air guide mounting slots 761, the multiple protrusion air guide surfaces 311 of the air guide protrusions 31 are also spaced apart along the width direction of the volute air outlet 74, thereby ensuring the contact area between the airflow and the protrusion air guide surfaces 311 when the airflow passes through the volute air outlet 74, so as to ensure the buffering effect on the airflow.

[0077] In addition, the width of the air guide mounting groove 761 located in the middle of the air guide mounting plate 76 can be set to be greater than the width of the air guide mounting grooves 761 located on both sides of the air guide mounting plate 76, so that the area of ​​the central boss air guide surface 311 is larger, thereby increasing the contact area between the airflow and the boss air guide surface 311, so as to improve the buffering effect of the airflow, reduce backflow, and increase the air volume.

[0078] In some embodiments, the air guide mounting plate 76 has an air guide surface 762 facing the air outlet 74 of the volute, and the boss air guide surface 311 is flush with the air guide surface 762.

[0079] Specifically, the air guide boss 31 of the volute tongue 3 can extend into the air guide mounting groove 761 and extend towards the air outlet 74 of the volute. The side of the air guide boss 31 facing the air outlet 74 of the volute forms a boss air guide surface 311, allowing the airflow at the air outlet 74 of the volute to flow through the boss air guide surface 311, thus buffering and guiding the airflow. Figure 5 as well as Figure 9 As shown, the air guide mounting plate 76 also has an air guide surface 762. The air guide surface 762 is formed on the side of the air guide mounting plate 76 facing the air outlet 74 of the volute. When the air guide boss 31 extends into the air guide mounting groove 761, the air guide surface 762 can be flush with the boss air guide surface 311. This makes the air guide mounting plate 76 and the side of the volute tongue 3 near the air outlet 74 of the volute form a complete curved surface, so as to reduce the wind resistance at the junction of the air guide boss 31 and the air guide mounting groove 761 and ensure the airflow velocity.

[0080] In some embodiments, the volute tongue 3 is detachably connected to the air guide mounting plate 76 via a connector 32. The volute tongue 3 is mounted on the air guide mounting plate 76, and as... Figures 7-8 As shown, the volute tongue 3 can be detachably connected to the air guide mounting plate 76 via the connector 32. The connector 32 can be a bolt or the like. The structure is simple, the installation cost is low, and it is easy to disassemble. Furthermore, the detachable connection of the volute tongue 3 to the air guide mounting plate 76 via the connector 32 allows the volute tongue 3 to be replaced, which facilitates the later maintenance of the volute tongue 3 and reduces maintenance costs.

[0081] In some embodiments, the volute 3 is provided with a first connecting hole 33, the air guide mounting plate 76 is provided with a connecting post 763, the connecting post 763 is formed with a second connecting hole 7631, and the connector 32 passes through the first connecting hole 33 and extends into the second connecting hole 7631 to be threadedly engaged with the connecting post 763.

[0082] Specifically, the volute tongue 3 is detachably connected to the air guide mounting plate 76 via the connector 32, and as shown... Figure 8As shown, the volute 3 is provided with a first connecting hole 33, and the air guide mounting plate 76 is provided with a connecting post 763, and the connecting post 763 is provided with a second connecting hole 7631. When the volute 3 is installed on the air guide mounting plate 76, part of the connecting post 763 can extend into the first connecting hole 33, and the connecting member 32 can be sequentially inserted into the first connecting hole 33 and the second connecting hole 7631 to engage with the connecting post 763 threadedly, thereby allowing the volute 3 to be installed on the air guide mounting plate 76.

[0083] Furthermore, the connecting post 763 is partially placed inside the first connecting hole 33, which can ensure the installation accuracy of the connector 32 and save installation time. A gasket 34 is provided on the side of the volute 3 away from the air guide mounting plate 76. The connector 32 can be sequentially inserted into the gasket 34, the first connecting hole 33 and the second connecting hole 7631. When the connector 32 is threaded with the connecting post 763, the connector 32 can press against the gasket 34 to avoid damage to the volute 3 and ensure the reliability of the connection.

[0084] In addition, in actual installation, multiple first connecting holes 33 and connecting posts 763 can be set and set one-to-one, so that multiple connectors 32 can be sequentially inserted into the corresponding first connecting holes 33 and second connecting holes 7631, ensuring connection reliability, reducing the force on each connector 32, ensuring the reliability of the connector 32, and extending the service life of the connector 32.

[0085] In some embodiments, the volute assembly 7 includes a volute body 71 and a volute cover 72. The volute body 71 is connected to the bottom of the housing 1. The volute cover 72 is detachably connected to the volute body 71 to jointly define the centrifugal air duct 75. The volute cover 72 and the volute body 71 jointly define the volute air outlet 74. The volute tongue 3 is installed on the volute cover 72.

[0086] Specifically, the body 1 contains a volute assembly 7, and as shown in the image. Figure 10 and Figures 12-14 As shown, the volute assembly 7 is provided with a volute body 71 and a volute cover 72. The volute body 71 can be connected to the bottom of the body 1, that is, the volute body 71 can be connected to the upper wall of the bottom of the body 1. The volute body 71 can be connected to the bottom inside the body 1 by means of integral molding or other methods, or it can be connected to the bottom inside the body 1 by means of connectors, etc., which is flexible in setting.

[0087] The volute cover 72 is connected to the volute body 71 and together with the volute body 71 defines the centrifugal air duct 75. The volute body 71 is connected to the bottom of the unit 1, that is, the centrifugal air duct 75 is also formed at the bottom of the unit 1. The centrifugal air duct 75 is connected to the volute air outlet 74. The volute air outlet 74 is directly opposite the unit air outlet 122, so that the volute air outlet 74 can be set close to the unit air outlet 122, so that the airflow can be directly output to the room through the unit air outlet 122 after being accelerated and pressurized by the centrifugal impeller 5, reducing energy loss, ensuring airflow speed, and improving the user experience.

[0088] Furthermore, the volute cover 72 is detachably connected to the volute body 71, and the volute body 71 can be fixedly connected to the bottom inside the machine body 1, so that the volute cover 72 is detachable relative to the machine body 1, which facilitates the installation of the centrifugal impeller 5. The volute cover 72 can be installed on the volute body 71 after the centrifugal impeller 5 is placed in the centrifugal air duct 75, which can ensure the reliability of the operation of the centrifugal impeller 5. Moreover, when the centrifugal impeller 5 needs to be maintained or cleaned in the future, the volute cover 72 can be separated from the volute body 71, which facilitates the maintenance of the centrifugal impeller 5 in the future and saves maintenance time.

[0089] Furthermore, the volute tongue 3 is installed on the volute cover 72, that is, the volute tongue 3 is set at the air outlet 74 of the volute, so that the airflow can flow along the volute tongue 3 when it flows through the air outlet 74 of the volute, so that the volute tongue 3 can guide the air to the air outlet 122 of the machine body. The volute tongue 3 is made of foam material, etc. After the high-speed airflow flowing out of the centrifugal impeller 5 in the centrifugal air duct 75 collides with the volute tongue 3, it can be buffered by the volute tongue 3, which can reduce the airflow returning to the centrifugal air duct 75, reduce the secondary flow formed at the volute tongue 3, and suppress the pressure pulsation generated on its surface, reduce the vibration and noise in the centrifugal air duct 75, and improve the user experience.

[0090] In some embodiments, the volute body 71 is provided with a snap-fit ​​portion 711, and the volute cover 72 is provided with a snap-fit ​​mating portion 721, and the snap-fit ​​portion 711 and the snap-fit ​​mating portion 721 are snap-fit ​​mating.

[0091] Specifically, the volute cover 72 is detachably connected to the volute body 71, and as... Figures 1-3 as well as Figures 12-14As shown, the volute body 71 is provided with a snap-fit ​​portion 711, which can be configured as a snap-fit ​​buckle, a snap-fit ​​protrusion, a snap-fit ​​groove, or a snap-fit ​​hole, etc. The volute cover 72 is provided with a snap-fit ​​mating portion 721, which can also be configured as a snap-fit ​​buckle, a snap-fit ​​protrusion, a snap-fit ​​groove, or a snap-fit ​​hole, etc. One of the snap-fit ​​portion 711 and the snap-fit ​​mating portion 721 is configured as a snap-fit ​​buckle, and the other is configured as a snap-fit ​​hole. That is, when the snap-fit ​​portion 711 is configured as a snap-fit ​​buckle, the snap-fit ​​mating portion 721 is configured as a snap-fit ​​hole, and when the snap-fit ​​mating portion 721 is configured as a snap-fit ​​buckle, the snap-fit ​​portion 711 is configured as a snap-fit ​​hole. In this embodiment, the snap-fit ​​portion 711 is configured as a snap-fit ​​buckle, and the snap-fit ​​mating portion 721 is configured as a snap-fit ​​hole.

[0092] Furthermore, when the volute cover 72 is installed on the volute body 71, the snap-fit ​​buckle can extend into the snap-fit ​​hole to engage with it, thereby allowing the volute cover 72 to be detachably installed on the volute body 71. Multiple snap-fit ​​parts 711 and multiple snap-fit ​​mating parts 721 can be configured, with each set corresponding to a specific part. When the centrifugal impeller 5 is operating, the volute cover 72 has a relative displacement tendency relative to the volute body 71, causing the snap-fit ​​parts 711 and 721 to be subjected to force. By setting multiple snap-fit ​​parts 711 and 721, the force can be distributed to multiple points, thereby reducing the effect of the force and preventing breakage of the snap-fit ​​parts 711 and 721, ensuring snap-fit ​​reliability and extending service life.

[0093] In some other embodiments, the volute body 71 is provided with a first positioning part 712, and the volute cover 72 is provided with a first positioning mating part 722, and the first positioning part 712 and the first positioning mating part 722 are positioned and mated.

[0094] Specifically, the volute cover 72 is detachably connected to the volute body 71, and as... Figures 1-3 as well as Figures 12-14 As shown, the volute body 71 is provided with a first positioning part 712, which can be configured as a positioning protrusion, a positioning groove, or a positioning hole, etc. The volute cover 72 is provided with a first positioning mating part 722, which can also be configured as a positioning protrusion, a positioning groove, or a positioning hole, etc. One of the first positioning part 712 and the first positioning mating part 722 is configured as a positioning protrusion, and the other is configured as a positioning groove. That is, when the first positioning part 712 is configured as a positioning protrusion, the first positioning mating part 722 is configured as a positioning groove, and when the first positioning mating part 722 is configured as a positioning protrusion, the first positioning part 712 is configured as a positioning groove. In this embodiment, the first positioning part 712 is configured as a positioning protrusion, and the first positioning mating part 722 is configured as a positioning groove.

[0095] Furthermore, when the volute cover 72 is installed on the volute body 71, the positioning protrusion can extend into the positioning groove to engage with it, thus facilitating accurate connection between the volute cover 72 and the volute body 71. This ensures the accuracy of the engagement between the snap-fit ​​part 711 and the snap-fit ​​mating part 721. Multiple first positioning parts 712 and multiple first positioning mating parts 722 can be configured, with each pair corresponding to the other. When the centrifugal impeller 5 is operating, the volute cover 72 has a relative displacement tendency relative to the volute body 71, causing the positioning engagement points of the first positioning parts 712 and the first positioning mating parts 722 to be subjected to force. By configuring multiple first positioning parts 712 and the first positioning mating parts 722, the force can be distributed to multiple points, thereby reducing the effect of the force and preventing breakage of the first positioning parts 712 and the first positioning mating parts 722, ensuring positioning reliability and extending service life.

[0096] In this embodiment, the edge of the connection between the volute body 71 and the volute cover 72 is provided with a limiting rib 713 and a rib groove 723. Alternatively, the rib groove 723 can be provided at the edge of the connection between the volute body 71 and the limiting rib 713 at the edge of the connection between the volute cover 72, or the limiting rib 713 can be provided at the edge of the connection between the volute body 71 and the rib groove 723 at the edge of the connection between the volute cover 72. In this embodiment, the edge of the connection between the volute cover 72 and the limiting rib 713 are provided. When the volute cover 72 is installed on the volute body 71, the limiting rib 713 can be placed within the rib groove 723, ensuring the reliability of the connection at the edge and the sealing of the connection, thus ensuring the airflow delivery effect.

[0097] In some embodiments, the air inlet 112 is located on the top wall 111 of the body 1, and / or the air outlet 122 is located on the bottom wall 121 of the body 1. The air inlet 112 can be located only on the top wall 111 of the body 1, or the air outlet 122 can be located only on the bottom wall 121 of the body 1, or the air inlet 112 can be located on the top wall 111 of the body 1, while the air outlet 122 is located on the bottom wall 121 of the body 1. The arrangement is flexible.

[0098] Specifically, the unit 1 is located on the outermost side of the air conditioner 100, and as follows: Figures 10-11 as well as Figure 22As shown, the unit 1 is provided with a chassis 12 and a front frame 11. The front frame 11 is detachably connected to the chassis 12 to form a complete unit 1. The front frame 11 and the chassis 12 can be connected by connectors, etc., which is convenient for installation and facilitates the maintenance and cleaning of the air conditioner 100 in the future. The front frame 11 is installed on the top of the chassis 12. The front frame 11 is provided with a top wall 111. The air inlet 112 of the unit can be set on the top of the front frame 11, that is, the air inlet 112 of the unit can be set on the top wall 111.

[0099] Furthermore, the air outlet 122 is formed on the chassis 12, so that the air inlet 112 is located at the top of the body 1 and the air outlet 122 is located at the bottom of the body 1. The heat exchanger assembly 2 is detachably installed on the face frame 11, which can increase the heat exchange time of the airflow in the body 1, ensure the heat exchange effect of the airflow, and thus ensure the performance of the air conditioner 100. Moreover, the air outlet 122 is located on the chassis 12, so that the airflow can blow downward, increase the heat radiation range of the air conditioner 100, improve the heating speed, and ensure user comfort.

[0100] In some other embodiments, the volute air outlet 74 is located on the bottom wall 121 of the volute assembly 7, and the volute air outlet 74 is open downwards and directly facing the body air outlet 122.

[0101] Specifically, the unit 1 is provided with a bottom wall 121. When the unit 1 is installed on a wall, the bottom wall 121 is located at the bottom of the unit 1, and the unit air outlet 122 is located on the bottom wall 121 of the unit 1. The volute assembly 7 is also connected to the bottom wall 121 of the unit 1, and the volute air outlet 74 is located on the bottom wall 121 of the volute assembly 7. The volute air outlet 74 faces downward and is open to the unit air outlet 122, that is, the unit air outlet 122 is located below the unit 1, so that high temperature airflow or low temperature airflow can be delivered to the unit air outlet 122 through the volute air outlet 74, and then delivered to the lower part of the unit 1 through the unit air outlet 122, so that the air conditioner 100 can deliver air close to the wall.

[0102] Furthermore, when the air conditioner 100 is in heating mode, the density of the high-temperature airflow is relatively low. Under natural conditions, the high-temperature airflow will flow upward. By placing the air outlet 122 of the unit on the bottom wall 121 and opening it downward, the high-temperature airflow can be delivered a long distance to the bottom of the room while adhering closely to the wall. This ensures the reliability of the downward delivery of the high-temperature airflow, improves the heating speed of the air conditioner 100, and increases the radiation range of the hot airflow, thereby ensuring the heating effect of the air conditioner 100 and improving the user experience.

[0103] In other embodiments, there are two volute air inlets 73, and the two volute air inlets 73 are located at the two ends of the volute assembly 7, respectively.

[0104] Specifically, when the centrifugal fan 5 rotates, the airflow after heat exchange flows into the centrifugal duct 75, so that it is accelerated by the centrifugal fan 5 and delivered outdoors, and as... Figures 12-14 As shown, the volute assembly 7 has a volute air inlet 73, which is connected to the centrifugal air duct 75. This allows the airflow after heat exchange to enter the centrifugal air duct 75 through the volute air inlet 73. There are two volute air inlets 73, which are respectively located at both ends of the volute assembly 7, that is, both ends of the centrifugal air duct 75 are provided with volute air inlets 73. The two volute air inlets 73 are respectively connected to the two axial ends of the centrifugal impeller 5. When the centrifugal impeller 5 rotates, the two volute air inlets 73 can simultaneously deliver airflow into the centrifugal air duct 75, thereby increasing the airflow delivery speed, ensuring the airflow volume of the air conditioner is 100, and the centrifugal impeller 5 can centrifugally deliver the airflow, which can increase the airflow velocity and air pressure, ensuring the airflow velocity delivered to the room and improving the user experience.

[0105] In some embodiments, the air conditioner 100 further includes a drive structure 4 and a fan shaft 6, with a centrifugal fan 5 mounted outside the fan shaft 6, and the drive structure 4 connected to the fan shaft 6 to drive the centrifugal fan 5 to rotate.

[0106] Specifically, the air conditioner 100 also includes a drive structure 4 and a fan shaft 6. The centrifugal fan 5 is mounted outside the fan shaft 6 and fixedly connected to the fan shaft 6. One end of the fan shaft 6 can be connected to the drive structure 4, and the other end is rotatably supported on the body 1, so that when the drive structure 4 is operating, it can drive the fan shaft 6 to rotate, thereby driving the centrifugal fan 5 to rotate. A wheel shaft mounting seat 65 is provided at the bottom inside the body 1. A mounting bearing 651 is detachably mounted on the wheel shaft mounting seat 65. A bearing shaft 64 is formed at one end of the fan shaft 6 near the wheel shaft mounting seat 65. The bearing shaft 64 can extend into the mounting bearing 651, so that the mounting bearing 651 can support the fan shaft 6 and ensure the reliability of the rotation of the fan shaft 6, reduce the friction generated when the fan shaft 6 rotates, reduce power loss, and reduce the operating energy consumption of the air conditioner 100.

[0107] Furthermore, such as Figures 13-16 As shown, the drive structure 4 is provided with a drive motor 41 and a motor mounting base 42. The motor mounting base 42 is provided with a mounting base body 43 and a mounting cover 44. The mounting base body 43 can be connected to the machine body 1. The mounting cover 44 is connected to the mounting base body 43 and can jointly define the motor mounting space 46 with the mounting base body 43. The mounting base body 43 is connected to the machine body 1, so that the drive motor 41 is fixed relative to the machine body 1 after being installed in the motor mounting space 46. The motor mounting space 46 is open on the side facing the wind turbine shaft 6, so that the drive motor 41 can be poweredly connected to the wind turbine shaft 6, thereby ensuring the reliability of the drive motor 41 driving the wind turbine shaft 6.

[0108] Furthermore, the mounting cover 44 is detachably connected to the mounting base body 43, and the mounting base body 43 can be fixedly connected to the bottom inside the machine body 1, making the mounting cover 44 detachable relative to the machine body 1. This facilitates the installation of the drive motor 41. The mounting cover 44 can be installed on the mounting base body 43 after the drive motor 41 is placed in the motor mounting space 46, which can ensure the reliability of the drive motor 41 operation. Moreover, when the drive motor 41 needs to be maintained or cleaned in the future, the mounting cover 44 can be separated from the mounting base body 43, which facilitates the maintenance of the drive motor 41 in the future and saves maintenance time.

[0109] In addition, such as Figures 13-14 As shown, the mounting body 43 is provided with a mounting part 431, and the mounting cover 44 is provided with a mounting mating part 441. Both the mounting part 431 and the mounting mating part 441 are provided with mounting holes, and the mounting part 431 and the mounting mating part 441 are provided correspondingly. The bolt 45 is suitable for being inserted into the mounting part 431 and the mounting mating part 441 in sequence, that is, the bolt 45 can be inserted into the two mounting holes in sequence to connect the mounting cover 44 and the mounting body 43. The bolt 45 has a simple structure, low setting cost, and convenient installation, which can ensure the reliability of the connection between the mounting body 43 and the mounting cover 44.

[0110] Furthermore, when the mounting cover 44 is installed on the mounting base body 43, the mounting part 431 and the mounting mating part 441 are aligned, and the bolts 45 are sequentially inserted through the mounting part 431 and the mounting mating part 441 to detachably connect the mounting base body 43 and the mounting cover 44. Multiple mounting parts 431 and multiple mounting mating parts 441 can be provided, with each pair corresponding to the other. When the drive motor 41 is operating, the mounting cover 44 has a relative displacement tendency relative to the mounting base body 43, causing the bolts 45 inserted through the mounting part 431 and the mounting mating part 441 to be subjected to force. By providing multiple mounting parts 431 and mounting mating parts 441, the force can be distributed to multiple locations, thereby reducing the effect of the force and preventing the bolts 45 from breaking, deforming, or coming loose, ensuring connection reliability and extending the service life of the bolts 45.

[0111] Furthermore, the mounting base body 43 is provided with a second positioning part 432, which can be configured as a positioning protrusion, a positioning groove, or a positioning hole, etc. The mounting cover 44 is provided with a second positioning mating part 442, which can also be configured as a positioning protrusion, a positioning groove, or a positioning hole, etc. One of the second positioning part 432 and the second positioning mating part 442 is configured as a positioning protrusion, and the other is configured as a positioning groove. That is, when the second positioning part 432 is configured as a positioning protrusion, the second positioning mating part 442 is configured as a positioning groove, and when the second positioning mating part 442 is configured as a positioning protrusion, the second positioning part 432 is configured as a positioning groove. In this embodiment, the second positioning part 432 is configured as a positioning groove, and the second positioning mating part 442 is configured as a positioning protrusion.

[0112] Furthermore, when the mounting cover 44 is installed on the mounting base body 43, the positioning protrusion can extend into the positioning groove to engage with the positioning groove, thereby facilitating the accurate connection between the mounting cover 44 and the mounting base body 43. This ensures the alignment of the mounting part 431 and the mounting mating part 441, thereby ensuring the accuracy of the connector insertion and improving the installation speed. In addition, multiple second positioning parts 432 and multiple second positioning mating parts 442 can be provided, with each of the multiple second positioning parts 432 and multiple second positioning mating parts 442 corresponding to each other.

[0113] When the drive motor 41 is operating, the mounting cover 44 has a relative displacement tendency with respect to the mounting body 43, which causes the positioning mating part of the second positioning part 432 and the positioning mating part 442 to be subjected to force. By providing multiple second positioning parts 432 and second positioning mating parts 442, the force can be distributed to multiple points, thereby reducing the effect of the force and preventing the second positioning parts 432 and the second positioning mating parts 442 from breaking, ensuring positioning reliability and extending service life.

[0114] In addition, the second positioning and mating part 442 can be provided at the lower end of the mounting cover 44 and has an arc-shaped protrusion. The second positioning part 432 can be configured as an arc-shaped groove. The arc-shaped protrusion can be inserted into the arc-shaped groove in the circumferential direction, which can ensure the installation accuracy and limit the lower end of the mounting cover 44 to ensure the installation stability.

[0115] In some embodiments, the drive motor 41 is provided with a motor shaft 411, which can pass through the motor mounting space 46 and extend toward the wind turbine shaft 6, so that the motor shaft 411 can be fixedly connected to the wind turbine shaft 6, thereby enabling the motor shaft 411 to rotate when the drive motor 41 is running, so as to drive the wind turbine shaft 6 to rotate together.

[0116] Specifically, the end of the impeller shaft 6 is provided with a connecting hole 61, which is coaxially arranged with the impeller shaft 6 and opens towards the motor shaft 411, allowing the motor shaft 411 to extend into the connecting hole 61. The impeller shaft 6 is also provided with a through hole 62, which is located on the outer peripheral wall of the impeller shaft 6 and extends radially, allowing the through hole 62 to communicate with the connecting hole 61. A limiting groove 412 is formed on the outer peripheral wall of the motor shaft 411. 2 and the through hole 62 can be distributed radially, and the positioning member 63 can be inserted into the through hole 62. The end of the positioning member 63 can press against the limiting groove 412 of the motor shaft 411 so that the positioning member 63 can be limited and pressed against the motor shaft 411, thereby allowing the motor shaft 411 to be circumferentially limited and engaged with the wind turbine shaft 6, so that the motor shaft 411 and the wind turbine shaft 6 are fixedly connected. The connection method is simple and can ensure the installation cost. The positioning member 63 can also be a bolt, etc.

[0117] In some embodiments, there are multiple centrifugal impellers 5, and the multiple centrifugal impellers 5 are installed at intervals along the axial direction of the impeller shaft 6. There are multiple volute assemblies 7, and the multiple centrifugal impellers 5 are installed in the multiple volute assemblies 7 in a one-to-one correspondence.

[0118] Specifically, a centrifugal fan 5 is installed inside the body 1, and as follows: Figure 10 as well as Figure 22 As shown, multiple centrifugal impellers 5 are configured, i.e., two, three, or four centrifugal impellers 5 are provided. The multiple centrifugal impellers 5 are spaced apart along the axial direction of the impeller shaft 6. The multiple centrifugal impellers 5 are all sleeved on the outside of the impeller shaft 6 and are all fixedly connected to the impeller shaft 6. When the drive structure 4 drives the impeller shaft 6 to rotate, the multiple centrifugal impellers 5 can rotate with the impeller shaft 6. The multiple centrifugal impellers 5 are correspondingly provided with multiple volute air outlets 74 and multiple body air outlets 122, so that the multiple centrifugal impellers 5 can deliver air to the outside, improve the air delivery efficiency, expand the air delivery range of the air conditioner 100, improve the cooling or heating effect of the air conditioner 100, and ensure the user experience.

[0119] Furthermore, multiple volute assemblies 7 are provided, and these volute assemblies 7 are spaced apart along the axial direction of the impeller shaft 6. Centrifugal air ducts 75 are formed inside each of the multiple volute assemblies 7. Multiple centrifugal impellers 5 are installed in the multiple volute assemblies 7 in a corresponding manner, so that when each centrifugal impeller 5 rotates, the airflow can flow to the corresponding centrifugal air duct 75. Multiple air outlets 122 are also provided, and each air outlet 122 is connected to the corresponding centrifugal air duct 75 through the volute air outlet 74. This allows each centrifugal impeller 5 to deliver air to the corresponding air outlet 122, ensuring the air volume of each air outlet 122 and thus ensuring the user experience.
