[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0030] Combination Figure 1-9As shown, this embodiment of the present disclosure provides an air conditioner including: a housing 100, a jet channel 200, a rotating part 300, and a jet outlet 301. The housing 100 includes an annular air outlet 101; the jet channel 200 is disposed at the center of the annular air outlet 101; the rotating part 300 is rotatably connected to one end of the jet channel 200 facing the annular air outlet 101, and closes that end; the jet outlet 301 is disposed on the rotating part 300.

[0031] The air conditioner provided in this embodiment has a rotating part 300 and a jet channel 200 for jetting at the circular part of the annular air outlet 101. The jet outlet 301 is disposed on the rotating part 300. As the rotating part 300 rotates, it changes the air outlet angle of the jet outlet 301. The high-speed airflow ejected from the jet outlet 301 drives the air outlet direction of the entire annular air outlet 101 to change. In turn, the air conditioner is driven to vent air through the jet, so that the whole has a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0032] Optionally, the housing 100 defines an air outlet cavity 102, and both the annular air outlet 101 and the other end of the jet channel 200 are connected to the air outlet cavity 102. In this way, both the annular air outlet 101 and the jet air outlet of the air conditioner are supplied with airflow from the air outlet cavity 102, simplifying the structure of the jet air outlet, and the temperature of the jet air outlet is the same as the temperature of the air outlet from the annular air outlet 101, which helps to maintain the stability of the overall air conditioner air outlet temperature.

[0033] Optionally, the jet channel 200 is connected to the jet fan 201, and the other end of the jet channel 200 is connected to the air outlet cavity 102 inside the housing 100. In this way, the jet channel 200 can draw air from inside the air outlet cavity 102, so that the jet and the air source of the air conditioner are consistent, and the temperature of the jet outlet air is the same as the temperature of the air outlet air 101, which is conducive to maintaining the stability of the overall air conditioner outlet temperature.

[0034] Optionally, the housing 100 is provided with a jet air inlet 103, the jet channel 200 is connected to the jet fan 201, and the air inlet end of the jet fan 201 is connected to the jet air inlet 103. In this way, the jet channel 200 draws air from outside the air conditioner, and the unheated or uncooled airflow outside the air conditioner mixes with the heated or cooled airflow inside the air conditioner, preventing the air conditioner's outlet temperature from being too high or too low, and improving the overall comfort of the air conditioner's airflow.

[0035] Optionally, a switching valve 202 is provided inside the jet channel 200. In this way, the switching valve 202 provided inside the jet channel 200 can control the opening or closing of the jet channel 200, thereby controlling the opening or closing of the jet air outlet or the size of the jet air outlet. By adjusting the jet air outlet, the air outlet of the annular air outlet 101 is affected, enabling the air conditioner to have a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0036] Optionally, a centrifugal fan 400 is installed inside the air outlet cavity 102, with the air outlet end of the centrifugal fan 400 facing the jet channel 300, and a heat exchanger 500 is installed between the centrifugal fan 400 and the jet channel 300. In this way, by using the centrifugal fan 400 to provide airflow, and by installing the heat exchanger 500 at the air outlet end of the centrifugal fan 400, a stable airflow that has undergone heat exchange through the heat exchanger 500 can be provided to the air conditioner.

[0037] Optionally, one end of the jet channel 200 faces the outlet of the centrifugal fan 400. This allows the air outlet of the centrifugal fan 400 to blow directly into the jet channel 200, making the jet air intake smoother and improving the jet efficiency.

[0038] Optionally, the heat exchanger 500 includes a first heat exchange plate and a second heat exchange plate. One side of the first heat exchange plate is connected to one side of the second heat exchange plate, and the first heat exchange plate and the second heat exchange plate have a set angle to form a conical structure, with the opening of the cone facing the air outlet of the centrifugal fan 400. In this way, the air outlet of the centrifugal fan 400 can pass through the heat exchanger 500 more evenly, thereby improving the heat exchange efficiency of the heat exchanger 500.

[0039] Optionally, a sealing baffle 401 is provided around the air outlet end of the centrifugal fan 400, which divides the air outlet cavity 102 into an upper part and a lower part. In this way, by setting the sealing baffle 401 at the air outlet end of the centrifugal fan 400 to separate the space defined inside the housing 100, the airflow at the air inlet and air outlet of the centrifugal fan 400 is prevented from mixing, thereby improving the stability of the air conditioning operation.

[0040] Optionally, the outlet of the centrifugal fan 400 is directed vertically towards the upper side inside the housing 100. This allows for efficient air delivery, reduces unnecessary wind resistance, and improves the air delivery efficiency of the centrifugal fan 400.

[0041] Optionally, the housing 100 has an air inlet grille 104 on its side, and the air inlet of the centrifugal fan 400 faces the air inlet grille 104. This facilitates the centrifugal fan 400 to draw air through the air inlet grille 104, making the airflow smoother, and the air inlet grille 104 effectively filters the airflow, making the air entering the air conditioner cleaner.

[0042] Optionally, the rotating part 300 has a bowl-shaped structure, and the jet outlet 301 is located within a preset distance from the circumference of the bowl-shaped structure. This bowl-shaped structure of the rotating part 300 facilitates installation on the inner side of the annular outlet, and the preset distance of the jet outlet 301 within the circumference of the bowl-shaped structure of the rotating part 300 brings the jet outlet 301 closer to the circumference of the bowl-shaped structure. This allows the jet airflow from the jet outlet 301 to be closer to the annular air outlet 101, better changing the airflow direction of the annular air outlet 101. This enables the air conditioner to have various airflow modes, meeting diverse needs for different airflow patterns.

[0043] Optionally, the jet nozzle 301 protrudes from the bowl-shaped structure and is inclined. This protrusion of the jet nozzle 301 from the bowl-shaped structure increases its range, allowing the airflow to travel further. Furthermore, the inclined arrangement of the jet nozzle 301 on the bowl-shaped structure allows the airflow ejected from it to form an angle with the air outlet of the air conditioner, better driving changes in the overall air outlet angle of the air conditioner. This enables the air conditioner to have various air outlet modes, further improving the air outlet effect.

[0044] Optionally, a guide vane 206 is provided on one side of the jet outlet 301. In this way, the guide vane 206 is provided on one side of the jet outlet 301, which has the function of guiding the air outlet of the jet outlet 301, changing the air outlet direction of the jet outlet 301, and increasing the air delivery distance of the jet outlet. In turn, the airflow ejected from the jet outlet 301 drives the overall air outlet angle of the air conditioner to shift, so that the air conditioner can have a variety of air outlet modes.

[0045] Optionally, the guide vane 206 is disposed on the side of the jet outlet 301 away from the center of the rotating part 300, and the guide vane 206 is inclined as a whole towards the center of the rotating part 300. In this way, it has a guiding effect on the air outlet of the jet outlet 301, causing the air outlet direction of the jet outlet 301 to deviate towards the center of the rotating part 300, thereby changing the air outlet direction of the jet outlet 301 and improving the air outlet effect.

[0046] Optionally, the preset distance is less than or equal to one-third of the radius of the bowl-shaped structure. If the preset distance is greater than one-third of the radius of the bowl-shaped structure, the airflow ejected from the jet nozzle 301 will be farther from the air outlet of the air conditioner, thus reducing the impact of the airflow ejected from the jet nozzle 301 on the air outlet of the air conditioner. This would prevent the air outlet of the air conditioner from shifting with the airflow ejected from the jet nozzle 301, thereby reducing the overall airflow efficiency of the air conditioner. Therefore, setting the preset distance to less than or equal to one-third of the radius of the bowl-shaped structure not only allows the airflow ejected from the jet nozzle 301 to be closer to the air outlet of the air conditioner, and the air outlet of the air conditioner will also shift with the airflow ejected from the jet nozzle 301, improving the overall airflow efficiency of the air conditioner, but also allows the airflow ejected from the jet nozzle 301 to form a certain angle with the air outlet of the air conditioner, better driving changes in the overall air outlet angle of the air conditioner, thus enabling the air conditioner to have a variety of air outlet modes.

[0047] Understandably, the preset distance is the distance between the circumference of the bowl-shaped structure and the jet opening 301.

[0048] Alternatively, a bowl-shaped structure refers to a structure that protrudes outward from the middle, narrows towards the center at the mouth and bottom, and has a smaller diameter at the mouth than at the middle. This makes the outer surface of the bowl-shaped structure arc-shaped, which, when applied to an air conditioner, guides the airflow and improves the air conditioner's efficiency.

[0049] Optionally, the opening of the bowl-shaped structure is positioned facing one end of the jet channel 200. In this way, the airflow in the jet channel 200 enters the rotating part 300 through the opening of the bowl-shaped structure, allowing the airflow in the jet channel 200 to enter the rotating part 300 stably, making the airflow smoother and improving the stability of the airflow.

[0050] Optionally, the bottom of the bowl-shaped structure is an arc-shaped surface. In this way, the arc-shaped surface structure can guide the airflow of the air conditioner and cooperate with the air outlet of the air conditioner to make the airflow of the air conditioner ring-shaped. The rotating part 300 can better drive the ring-shaped airflow offset, so that the air conditioner as a whole has a variety of air outlet modes and improves the air outlet effect.

[0051] Optionally, one end of the jet channel 200 is provided with a horn-shaped connecting structure 203, and the diameter of the rim of the horn-shaped connecting structure 203 is the same as the diameter of the rim of the bowl-shaped structure. In this way, the jet channel 200 is connected to the bowl-shaped structure through the horn-shaped connecting structure 203. When installed in an air conditioner, the horn-shaped connecting structure 203 has a circumferential guiding effect on the airflow flowing outside it, so that the airflow forms an annular air outlet area under the guidance of the horn-shaped connecting structure 203, thereby improving the air outlet efficiency of the air conditioner.

[0052] Optionally, the rim of the flared connecting structure 203 and the rim of the bowl-shaped structure are connected by a bearing. This bearing makes the connection between the flared connecting structure 203 and the bowl-shaped structure more flexible, allowing relative rotation between them and improving the stability of the rotating part 300 of the bowl-shaped structure.

[0053] Optionally, the center of the rotating part 300 and the center of the jet channel 200 are on the same axis. This ensures that the airflow in the jet channel 200 can flow smoothly and stably to the rotating part 300, further improving the airflow efficiency.

[0054] Optionally, one end of the horn-shaped connecting structure 203 is a first circular connecting port 204, and the other end is a second circular connecting port 205. The first circular connecting port 204 is connected to one end of the jet channel 200, and the second circular connecting port 205 is connected to one end of the rotating part 300. In this way, by connecting the first circular connecting port 204 and the second circular connecting port 205 of the horn-shaped connecting structure 203 to the jet channel 200 and the rotating part 300 respectively, the horn-shaped connecting structure 203 can tightly connect the jet channel 200 and the rotating part 300, ensuring that the airflow flows smoothly and stably from the jet channel 200 to the rotating part 300.

[0055] Optionally, the diameter of the first circular connection port 204 is smaller than the diameter of the second circular connection port 205. This allows the horn-shaped connection structure 203 to more tightly connect the bowl-shaped structure to the jet channel 200. When installed in an air conditioner, the air outlet passes through the horn-shaped connection structure 203, which guides the airflow passing through it. Combined with the air outlet, this creates a ring-shaped airflow, giving the air conditioner a variety of airflow modes and improving its overall airflow performance.

[0056] Optionally, the diameter of the first circular connection port 204 is half the diameter of the second circular connection port 205. This allows for stable guidance of the airflow passing through the horn-shaped connection structure 203, and, in conjunction with the air conditioner's outlet, ensures that the air conditioner's airflow is circular, thus enabling the air conditioner to have a variety of airflow modes and further improving its airflow performance.

[0057] Optionally, the air conditioner also includes a drive unit 600. The drive unit 600 is connected to the rotating part 300 and configured to drive the rotating part 300 to rotate. In this way, the drive unit 600 provides power to the rotating part 300, so that the jet port 301 can rotate with the rotating part 300. As a result, when the airflow in the jet channel 200 is ejected through the jet port 301, the direction of the jet changes with the rotation of the rotating part 300, thereby changing the overall air outlet direction of the air conditioner.

[0058] Optionally, the drive device 600 includes: a ring gear 601, a gear 602, and a drive motor 603. The ring gear 601 is fixedly connected to one side of the rotating part 300, the gear 602 meshes with the ring gear 601, and the output shaft of the drive motor 603 is connected to the gear 602. Thus, the gear 602 rotates under the drive of the drive motor 603, and through the meshing structure between the gear 602 and the ring gear 601, it drives the ring gear 601 to rotate, thereby driving the rotating part 300 to rotate. This makes the drive more direct and efficient. Furthermore, under the drive of the drive device 600, the position of the jet outlet 301 on the rotating part 300 changes accordingly, thereby changing the direction of the airflow ejected from the jet outlet 301, allowing the jet outlet 301 to discharge air in multiple directions. The ring gear 601 is located on the side of the rotating part 300 connected to the trumpet-shaped connecting structure 203.

[0059] Optionally, the drive motor 603 is fixedly installed inside the horn-shaped connecting structure 203. This not only makes reasonable use of the internal space of the horn-shaped connecting structure 203 and prevents the drive motor 603 from occupying a large installation space of the rotating part 300, but also ensures that the drive motor 603 does not affect the rotation of the rotating part 300, thereby improving the stability of the rotating part 300 during rotation.

[0060] Optionally, the drive motor 603 is fixed to the inner wall of the horn-shaped connecting structure 203 or the conical channel via the motor bracket 604. This makes the drive motor 603 more securely fixed and improves the stability of the rotation of the drive rotating part 300.

[0061] Optionally, the rotating part 300 includes an airflow passage 207. The airflow passage 207 is disposed inside the rotating part 300, with one end connected to the jet channel 200 and the other end connected to the jet outlet 301. In this way, the airflow is transported from the jet channel 200 to the jet outlet 301 through the airflow passage 207, so that the airflow can be kept smooth during the rotation of the rotating part 300, thereby improving the stability of the jet airflow.

[0062] Optionally, the airflow passage 207 and the jet channel 200 are rotatably connected. This rotatable connection makes the connection between the airflow passage 207 and the jet channel 200 more flexible, ensuring that relative rotation can occur between the airflow passage 207 and the jet channel 200, preventing the jet channel 200 from affecting the rotation of the airflow passage 207, and improving the stability of the rotation of the airflow passage 207.

[0063] Optionally, the airflow passage 207 is offset from the center of the rotating part 300 to the periphery. In this way, the direction of the airflow is changed by the offset airflow passage 207, thereby enabling the airflow to flow more efficiently and stably toward the jet outlet 301, reducing airflow resistance and improving the stability of the jet outlet.

[0064] Optionally, the flow area of ​​the airflow passage 207 gradually decreases from the jet channel 200 to the jet outlet 301. This causes the flow area of ​​the airflow within the airflow passage 207 to gradually decrease along the flow direction, converting static pressure into dynamic pressure and increasing the airflow velocity at the jet outlet 301. This allows the jet to maintain a higher flow velocity, which in turn better drives the deflection of the airflow direction of the annular air outlet 101, enabling the air conditioner to have various airflow modes to meet diverse needs.

[0065] Optionally, the maximum flow area of ​​the airflow passage 207 is greater than or equal to twice its minimum flow area, and less than or equal to four times its minimum flow area. Thus, when the maximum flow area of ​​the airflow passage 207 is less than twice its minimum flow area, the difference between the maximum and minimum flow areas is too small, resulting in a weak funnel effect within the airflow passage 207. This reduces the efficiency of the airflow converting from static pressure to dynamic pressure, leading to a slower increase in airflow velocity and consequently reducing the outlet velocity of the jet nozzle 301, thus diminishing the jetting effect. Conversely, when the maximum flow area of ​​the airflow passage 207 is more than four times its minimum flow area, the difference between the maximum and minimum flow areas is too large, causing the airflow to flow too quickly towards the minimum flow area. This results in excessive airflow accumulation and congestion within the airflow passage 207, leading to excessive wind resistance and affecting normal airflow. Therefore, setting the maximum flow area of ​​the airflow passage 207 to be between two and four times its minimum flow area allows for a funnel effect during airflow within the passage, increasing airflow velocity, while also reducing wind resistance and ensuring more stable airflow.

[0066] Optionally, the maximum flow area of ​​the airflow passage 207 is three times its minimum flow area. This ensures stable airflow within the airflow passage 207 while creating a funnel effect during the flow, increasing the airflow velocity and thus enhancing the jet effect.

[0067] Optionally, the jet outlet 301 has an arc-shaped structure. This creates an arc-shaped airflow effect, matching the airflow from the annular air outlet 101. This allows the jet outlet to better influence the airflow from the annular air outlet 101, causing it to deflect. Furthermore, the arc-shaped jet outlet 301 increases the area of ​​the jet outlet, further influencing the airflow from the annular air outlet 101 and more efficiently shifting its direction. This results in the air conditioner having a variety of airflow modes to meet diverse user needs.

[0068] Optionally, the arc of the jet nozzle 301 is greater than or equal to π / 3 and less than or equal to 2π / 3. When the arc of the jet nozzle 301 is less than π / 3, the nozzle becomes too small, causing airflow to accumulate at the nozzle, resulting in airflow congestion and preventing rapid ejection, thus reducing jet velocity and effect. When the arc of the jet nozzle 301 is greater than π / 3, the airflow is too smooth and cannot be ejected at high speed, causing the airflow from the nozzle to fail to affect the overall airflow of the air conditioner, reducing the airflow effect. Setting the arc between 2π / 3 and π / 3 allows the airflow from the jet nozzle 301 to better drive changes in the overall airflow angle of the air conditioner, causing the airflow to shift and thus improving the jet effect.
