Detailed Implementation

[0034] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0035] This embodiment provides a cabinet-type air conditioner, such as... Figures 1-3 As shown, the device includes a housing 100, which has an air inlet 170 and a main air outlet 131 located above the air inlet 170. A first mixed-flow fan 200 is provided inside the housing 100. The first mixed-flow fan 200 is located in the junction area between the air inlet 170 and the main air outlet 131. The first mixed-flow fan 200 is arranged horizontally, and the air intake of the first mixed-flow fan 200 is located at its bottom and faces downward, while the air exhaust is located at its top and faces upward.

[0036] In the cabinet air conditioner provided in this embodiment, the housing 100 forms an air duct 180. The air inlet 170 is located below the main air outlet 131. The first mixed-flow fan 200 is housed in the air duct 180 and is located at the junction of the air inlet 170 and the main air outlet 131. Specifically, the air intake of the first mixed-flow fan 200 is located at its bottom end and the air exhaust is located at its top end. The air intake of the first mixed-flow fan 200 can be located above the air inlet 170 or at the top edge of the air inlet 170. The air exhaust of the first mixed-flow fan 200 can be located below the main air outlet 131 or at the bottom edge of the main air outlet 131. The bottom air intake of the first mixed-flow fan 200 faces downward and the top air exhaust faces upward. The flow direction of the internal flow channel of the first mixed-flow fan 200 is consistent with the arrangement direction of the relative positions of the air inlet 170 and the main air outlet 131.

[0037] The first mixed-flow fan 200 is defined with its air intake port 210 and exhaust port 220. During operation, the first mixed-flow fan 200 starts running, with the air inlet 170 approximately entirely below the first air intake port 210. The first air intake port 210 generates an upward suction effect on the entire air inlet 170. Under this suction effect, indoor air flows into the air duct 180 through the air inlet 170 and then turns upwards, entering the flow path of the first mixed-flow fan 200 through the first air intake port 210. The airflow then... The air inlet 170 flows into the air duct 180 and then into the first air intake 210 in the same direction. At the same time, the main air outlet 131 is located almost entirely above the first exhaust outlet 220. The first exhaust outlet 220 can discharge airflow to the main air outlet 131, which covers a large air outlet area. The airflow flows into the air duct 180 through the first exhaust outlet 220 and then into the main air outlet 131 in a consistent flow. Furthermore, the airflow blows forward over a large area through the main air outlet 131, thereby completing the temperature regulation of the indoor environment.

[0038] In this embodiment of the cabinet air conditioner, on the one hand, a compact, high-volume, and low-noise first mixed-flow fan 200 is used as the power source, which can effectively improve the air volume and temperature regulation effect of the cabinet air conditioner. At the same time, it can also reduce the overall size of the cabinet air conditioner, reduce its space occupation, reduce its operating noise, and improve its layout convenience and user comfort. On the other hand, the first mixed-flow fan 200 is located in the junction area between the air inlet 170 and the main air outlet 131, and its flow direction is consistent with the relative position of the air inlet 170 and the main air outlet 131. During operation, the overall airflow in the air duct 180 is relatively smooth, thereby reducing the impact of airflow disturbance on the air volume and the noise pollution generated. Accordingly, the air volume and temperature regulation effect of the cabinet air conditioner are further improved, and the noise pollution generated during its operation is effectively reduced, thus improving the user comfort of the cabinet air conditioner.

[0039] In this embodiment, as Figure 1 and Figure 3As shown, the housing 100 has a lower air outlet 132 located below the air inlet 170. A second mixed-flow fan 300 is installed inside the housing 100. The air intake of the second mixed-flow fan 300 is located at its top, and the air exhaust of the second mixed-flow fan 300 is located at its bottom and adjacent to the lower air outlet 132. The housing 100 specifically includes a top plate 110, a bottom plate 120, and a side panel 10A connecting the two. The side panel 10A includes an upper cylindrical section 10a and a lower cylindrical section 10b from top to bottom. The main air outlet 131 is located in the upper cylindrical section 10a, and the extension area of ​​the main air inlet 170 in the vertical direction is 1 / 3 to 1 / 2 of the overall height of the side panel 10A. The air inlet 170 is located in the lower cylindrical section 10b, and the lower air outlet 132 is located in the bottom area of ​​the lower cylindrical section 10b.

[0040] During use, users can choose to activate the first mixed-flow fan 200 and the second mixed-flow fan 300 according to their needs, so that the cabinet air conditioner enters different temperature adjustment modes and adjusts the indoor temperature accordingly, thereby improving the functionality of the cabinet air conditioner. The air intake of the second mixed-flow fan 300 is defined as the second air intake, and the air exhaust outlet as the second air exhaust outlet. When the second mixed-flow fan 300 is activated, since it is located in the lower area of ​​the air duct 180 and is situated between the lower air outlet 132 and the air inlet... In the junction area of ​​air inlet 170, when the second mixed flow fan 300 is running, the second air inlet at its top can generate a downward suction effect on the air inlet 170. The air flows into the air duct 180 through the air inlet 170 and turns downward to enter the flow channel of the second mixed flow fan 300 through the second air inlet, and the overall flow direction of the airflow is consistent. At the same time, the lower air outlet 132 is located below the second air outlet of the second mixed flow fan 300. The second air outlet can blow air outward at a low position and with high flow consistency through the lower air outlet 132.

[0041] Specifically, in this embodiment, when the cabinet air conditioner has a main air inlet 170 located in the upper larger area and a lower air outlet 132 located at the bottom, the cabinet air conditioner can be controlled to enter a rapid temperature adjustment mode, a cooling mode, or a heating mode according to the start / stop status of the first mixed-flow fan 200 and the second mixed-flow fan 300.

[0042] In the rapid temperature adjustment mode, both the first mixed-flow fan 200 and the second mixed-flow fan 300 are activated. When the user needs the indoor environment to quickly reach the target temperature, the cabinet air conditioner can be adjusted to enter the rapid temperature adjustment mode, and the first mixed-flow fan 200 and the second mixed-flow fan 300 will be activated accordingly. The first mixed-flow fan 200 and the second mixed-flow fan 300 are located at the upper and lower ends of the air inlet 170, respectively. Under the suction action of the first mixed-flow fan 200 and the second mixed-flow fan 300, the indoor air flows into the air duct 180 through the upper area of ​​the air inlet 170, enters the first mixed-flow fan 200 upward, and is blown forward at a high position and over a wide area through the main air outlet 131; the air flowing into the air duct 180 through the lower area of ​​the air inlet 170 enters the second mixed-flow fan 300 downward and is blown forward at a low position through the lower air outlet 132, thereby forming a large airflow area at the front of the cabinet air conditioner to achieve rapid temperature adjustment of the indoor environment. Specifically, the rapid temperature adjustment mode can be used for either cooling or heating.

[0043] In cooling mode, the first mixed-flow fan 200 starts and the second mixed-flow fan 300 stops. When the user needs the cabinet air conditioner to maintain cooling regulation of the indoor environment, the cabinet air conditioner can be adjusted to enter cooling mode, and the first mixed-flow fan 200 will start accordingly while the second mixed-flow fan 300 remains off. Under the suction action of the first mixed-flow fan 200, the indoor air flows into the air duct 180 through the air inlet 170 and then all of it enters the first mixed-flow fan 200 upwards. It is then blown forward at a high position and over a wide area through the main air outlet 131. The cold air at a higher position gradually descends during the forward flow, thereby maintaining cooling regulation of the indoor environment and ensuring uniform temperature regulation.

[0044] In heating mode, the first mixed-flow fan 200 is turned off, and the second mixed-flow fan 300 is turned on. When the user needs the cabinet air conditioner to maintain the heating regulation of the indoor environment, the cabinet air conditioner can be adjusted to enter the heating mode, and the second mixed-flow fan 300 will be turned on accordingly while the first mixed-flow fan 200 remains off. Under the suction action of the second mixed-flow fan 300, the indoor air flows into the air duct 180 through the air inlet 170 and then all enters the second mixed-flow fan 300 downwards. It is then blown forward at a low position through the lower air outlet 132. The lower-positioned hot air gradually rises during the forward flow, thereby maintaining the heating regulation of the indoor environment and ensuring the uniformity of temperature regulation.

[0045] In this embodiment, as Figures 1-3As shown, the top of the housing 100 is provided with a top air outlet 111. When the first mixed-flow fan 200 is started, in addition to being blown forward over a large area through the main air outlet 131, the airflow can also be blown upward over a small area through the top air outlet 111. The airflow blown out through the top air outlet 111 is at a relatively high height, which can further improve the uniformity of temperature regulation while ensuring the regulation of indoor ambient temperature, thereby further increasing the diversity of air outlet modes of the cabinet air conditioner and improving its functionality.

[0046] Specifically, such as Figures 1-3 As shown, the top air outlet 111 is located on the top plate 110; or, as... Figures 5-7 As shown, the top air outlet 111 can be formed by a spaced arrangement between the top of the top plate 110 and the top of the side panel 10A.

[0047] In this embodiment, as Figure 3 and Figure 6 As shown, a first air guide assembly 600 is provided inside the housing 100. The first air guide assembly 600 is configured to guide the airflow blown out by the first mixed-flow fan 200 at the first air outlet to the main air outlet 131; as shown... Figure 3 and Figure 7 As shown, a second air guide assembly 700 is provided inside the housing 100. The second air guide assembly 700 is configured to guide the airflow blown by the first mixed-flow fan 200 at the second air outlet position to the top air outlet 111. The first mixed-flow fan 200 is an annular mixed-flow fan, with an annular flow channel 230 formed inside its housing. The axis of the annular flow channel 230 is consistent with the vertical direction. The first mixed-flow fan 200 can reach the first air outlet position or the second air outlet position by adjusting its air outlet direction and air outlet path. When the first mixed-flow fan 200 is located at the first air outlet position, the airflow blown through its first exhaust port 220 flows to the first air guide assembly 600, and under the guiding action of the first air guide assembly 600, flows vertically to different height areas of the main air outlet 131, so that the airflow can pass through the entire main air outlet 131. The airflow is blown forward over a large area with a high flow rate and relatively uniform distribution, ensuring the effectiveness of the main air outlet 131. When the first mixed-flow fan 200 is located at the second air outlet position, the airflow blown out through its first exhaust port 220 flows to the second air guide assembly 700, and under the guidance of the second air guide assembly 700, it flows upward to the top air outlet 111, and is blown outward at a high position and with a small area through the top air outlet 111, ensuring the effective airflow of the top air outlet 111 and reducing the occurrence of the airflow being blown outward through the main air outlet 131 during the upward flow of the airflow, which would lead to the top air outlet 111 being ineffective.

[0048] Specifically, such as Figure 6As shown, the first mixed-flow fan 200 is equipped with a high-speed motor 240, which has an annular flow channel 230, and a conical diffuser 250 is formed at the center of the annular flow channel 230. The outer periphery of the annular flow channel 230 is a guide ring 260, thereby forming an annular acceleration first exhaust port 220. The first exhaust port 220 of the first mixed-flow fan 200 is also provided with a ring of ribs 270 arranged at intervals along its circumference to achieve spiral high-speed airflow.

[0049] The structure of the second mixed-flow fan 300 can be the same as that of the first mixed-flow fan 200.

[0050] Specifically, the first air guide assembly 600 may include a plurality of air guide rings 610 arranged in a stacked and spaced manner along the vertical direction, and each air guide ring 610 is flared out from bottom to top.

[0051] In this embodiment, as Figures 1-3 As shown, when the top air outlet 111 is located on the top plate 110, the housing 100 also includes a guide protrusion 190 located above the top air outlet 111, and the sidewall of the guide protrusion 190 is concave or inclined from its middle part to its edge. The airflow blown upward through the top air outlet 111 comes into contact with the guide protrusion 190 and is dispersed and flows in all directions under the guiding action of the guide protrusion 190, so that the airflow can flow into the indoor space rather than the roof, thereby ensuring the temperature regulation effect of the top air outlet 111 on the indoor environment.

[0052] Similarly, such as Figures 5-7 As shown, when the top air outlet 111 is formed by the gap between the top of the top plate 110 and the top of the side plate 10A, the bottom of the top plate 110 is provided with a guide protrusion 190, and the side wall of the guide protrusion 190 is concave upward from the middle to the edge. When the first mixed flow fan 200 is in the second air outlet position and blows the airflow upward to the top area of ​​the upper cylinder section 10a through its first exhaust port 220, the airflow comes into contact with the guide protrusion 190 and disperses to the surroundings under the guiding action of the guide protrusion 190, and then blows it outward through the annular top air outlet 111, so as to improve the smoothness of airflow turning and distribution and reduce the disturbance and noise caused by the sharp turning of the airflow.

[0053] When a cabinet air conditioner is equipped with a main air outlet 131 and a top air outlet 111, the cooling mode of the cabinet air conditioner can specifically include a first cooling mode and a second cooling mode, depending on the air outlet status of the main air outlet 131 and the top air outlet 111.

[0054] In the first cooling mode, the first mixed-flow fan 200 starts and is positioned at the first air outlet. The airflow blown by the first mixed-flow fan 200 is blown outward through the main air outlet 131. This creates a large-scale airflow of cool air in the upper area of ​​the cabinet air conditioner, achieving rapid cooling and regulation of the upper area of ​​the cabinet air conditioner and the indoor environment.

[0055] In the second cooling mode, the first mixed-flow fan 200 starts and is positioned at the second air outlet. The airflow from the first mixed-flow fan 200 is blown outward through the top air outlet 111. This creates a cool airflow above the cabinet air conditioner, reducing direct airflow to the user while still cooling and regulating the indoor environment. This cooling mode is particularly suitable for continuous cooling after the indoor temperature has stabilized, improving user comfort and noise reduction while ensuring the indoor temperature remains stable at the target temperature.

[0056] In the rapid temperature adjustment mode and the cooling mode, when the first mixed-flow fan 200 is started, it can be adjusted to be located at the first air outlet or the second air outlet as needed. For example, in the rapid temperature adjustment mode, if the first mixed-flow fan 200 can be started and located at the first air outlet, the cabinet air conditioner will blow air forward through the main air outlet 131 and the lower air outlet 132; or, if the first mixed-flow fan 200 can be started and located at the second air outlet, the cabinet air conditioner will blow air through the top air outlet 111 and the lower air outlet 132.

[0057] In this embodiment, the air inlet 170 includes multiple air intake zones along the circumference of the housing 100, and the multiple air intake zones have different orientations. The arrangement of multiple air intake zones with different orientations serves two purposes: firstly, it increases the air intake area of ​​the air inlet 170, thereby ensuring both the intake and delivery air volume of the cabinet air conditioner, and consequently ensuring the temperature regulation effect of the cabinet air conditioner; secondly, the cabinet air conditioner is less restricted in its usage scenarios, and can be placed against a wall or in a corner, with the placement angle freely adjustable. Even if the wall and surrounding objects obstruct part of the air intake zone, the other unobstructed air intake zones of the air inlet 170 can still receive air normally, ensuring the normal use of the cabinet air conditioner, thus improving its applicability and ease of placement.

[0058] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the side panel 10A is prismatic in shape and specifically includes a front panel 130 at the front end, a back panel 160 at the rear end, a left side panel 140 connecting the left ends of the two, and a right side panel 150 connecting the right ends of the two. The air inlet 170 includes a forward air inlet area 171 on the front panel 130, a left air inlet area 172 on the left side panel 140, and a right air inlet area 173 on the right side panel 150. When a cabinet air conditioner is in use, its front is generally not obstructed by walls or objects. A front air intake zone 171 is set in the lower part of the front panel 130 to make full use of this area, effectively increasing the air intake area of ​​the air inlet 170 and ensuring effective air intake. At the same time, a left air intake zone 172 is set in the lower part of the left side panel 140 of the casing 100, and a right air intake zone 173 is set in the lower part of the right side panel 150 of the casing 100 to increase the air intake area of ​​the air inlet 170. Furthermore, the front air intake zone 171, the left air intake zone 172, and the right air intake zone 173 have different orientations, thereby effectively reducing the obstruction of the air inlet 170 when the cabinet air conditioner is arranged, and ensuring the normal use of the cabinet air conditioner.

[0059] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the left side panel 140 includes a first left panel area 141 and a second left panel area 142 from front to back. The second left panel area 142 extends obliquely to the right from front to back, and the left air intake area 172 is located in the second left panel area 142. The right side panel 150 includes a first right panel area 151 and a second right panel area 152 from front to back. The second right panel area 152 extends obliquely to the left from front to back, and the right air intake area 173 is located in the second right panel area 152. The first left panel 141, top panel 110, first right panel 151, and bottom panel 120 together form the front port of the housing 100. The first left panel 141 and first right panel 151 extend parallel to each other in the front-rear direction, thus forming a regularly shaped rectangular port at the front end of the housing 100. Furthermore, when a user looks at the cabinet air conditioner from directly in front, its left air intake area 172 and right air intake area 173 will not be visible, improving the regularity of the cabinet air conditioner's shape and its visual neatness; the second left panel 142 and the second right panel 120... 152 extends from front to back at an angle towards each other, and the rear ends of the two are respectively connected to the left and right sides of the back panel 160. When the user needs to place the back panel 160 of the cabinet air conditioner against the wall, since the extension directions of the first left panel area 141 and the second right panel area 152 are different from those of the back panel 160, the wall will not block the left air intake area 172 and the right air intake area 173, thereby ensuring the effective air intake of the left air intake area 172 and the right air intake area 173, and ensuring their contribution to the air intake area and air volume of the cabinet air conditioner.

[0060] In this embodiment, as Figure 2 and Figure 4As shown, the air inlet 170 may also include a rear air inlet area 174 located on the back panel 160. The rear air inlet area 174 can further increase the air intake area of ​​the cabinet air conditioner, improve its air intake volume and temperature regulation effect; at the same time, it can further reduce the orientation restrictions when arranging the cabinet air conditioner, and further improve the convenience and applicability of the cabinet air conditioner.

[0061] In this embodiment, as Figure 1 As shown, an air inlet grille 400 is magnetically connected to the front end of the forward air zone 171. The air inlet grille 400 shields the forward air zone 171, and the air inlet holes formed between its grille bars allow airflow to enter the air duct 180. While ensuring air intake, it isolates the inside and outside of the housing 100, protects the evaporator 800, the second mixed flow fan 300 and other components inside the housing 100, and reduces the risk of injury caused by users accidentally inserting their fingers into the air duct 180.

[0062] Similarly, such as Figure 1 As shown, when the main air outlet 131 is located on the front panel 130, the front end face of the main air outlet 131 is magnetically connected to the air outlet grille 500. The air outlet grille 500 covers the main air outlet 131, and the air outlet holes formed between its grilles allow airflow to be blown out. While ensuring airflow, it also protects components such as the first mixed-flow fan 200 inside the housing 100 and reduces the damage caused by users accidentally inserting their fingers into the air duct 180, thereby improving the operational safety of the cabinet air conditioner. In addition, the upper and lower areas of the front port of the housing 100 are respectively provided with air inlet grilles 400 and air outlet grilles 500 of the same form, which makes the front end arrangement of the housing 100 more consistent, thereby improving the visual neatness of the cabinet air conditioner.

[0063] Both the air inlet grille 400 and the air outlet grille 500 are magnetically connected to the housing 100. In use, simply align the air inlet grille 400 and the air outlet grille 500 to their respective positions to achieve magnetic connection to the housing 100, enabling convenient assembly. When cleaning or maintenance is required, simply pull the air inlet grille 400 and the air outlet grille 500 outwards to easily disassemble them, thereby improving the ease of assembly and disassembly of the air inlet grille 400 and the air outlet grille 500, and consequently improving the ease of assembly and maintenance of the cabinet air conditioner.

[0064] In addition to the aforementioned multiple dispersed air intake areas, the air inlet 170 can also extend in a ring shape along the circumference of the housing 100. The lower cylinder section 10b is provided with an air inlet 170 extending in a ring shape, capable of 360° air intake. In use, the air inlet 170 can allow air to enter and exit in 360°. On the one hand, the air intake area of ​​the air inlet 170 and the air outlet area are relatively large, ensuring both the air intake and air supply volume of the cabinet air conditioner, thereby ensuring the temperature regulation effect of the cabinet air conditioner. On the other hand, the use scenarios of the cabinet air conditioner are less restricted. The cabinet air conditioner can be placed in an open space indoors without obstruction, or it can be placed against a wall or in a corner, and the placement angle can be freely adjusted without restriction. Even if the wall and surrounding objects partially obstruct the air inlet 170 and the air outlet, the unobstructed areas of the air inlet 170 and the air outlet can still allow normal air intake and exhaust, ensuring the normal use of the cabinet air conditioner and further improving its applicability and ease of placement.

[0065] In addition to being located on the front panel 130, the main air outlet 131 can also extend in a ring along the circumference of the housing 100. The upper cylinder section 10a is provided with a main air outlet 131 that extends in a ring and can discharge air 360°. After heat exchange, the airflow can be delivered to various areas of the indoor environment in a 360° manner through the main air outlet 131, thereby quickly and evenly regulating the temperature of a large area of ​​the indoor environment and further improving the temperature regulation effect of the cabinet air conditioner.

[0066] Specifically, such as Figure 1 As shown, the side panel 10A is cylindrical, with the upper cylindrical section 10a being an annular air outlet grille and the lower cylindrical section 10b of the side panel 10A being an annular air inlet grille. The entire upper cylindrical section 10a is an annular grille, and the multiple air outlet areas formed by the grille plates or bars together constitute the main air outlet 131. The main air outlet 131 covers the entire area of ​​the upper cylindrical section 10a. Given a fixed volume of the housing 100, this maximizes the air outlet area of ​​the main air outlet 131, thereby ensuring the air volume and temperature regulation effect of the cabinet air conditioner. It also reduces the limitations on usage scenarios caused by obstruction of the main air outlet 131, improving its applicability and ease of installation. The lower cylindrical section 10b is an annular air inlet grille. The entire lower cylinder section 10b is in the form of a ring-shaped grille. The multiple air intake areas formed by the grille plates or grille bars of the air intake grille together form the air intake 170, and the air intake 170 covers the entire area of ​​the lower cylinder section 10b. With a fixed volume of the housing 100, the air intake area of ​​the air intake 170 is maximized, which further ensures the air volume and temperature regulation effect of the cabinet air conditioner. At the same time, it further reduces the limitation of the use scenarios caused by the obstruction of the air intake 170 of the cabinet air conditioner, and improves its applicability and ease of installation.

[0067] In addition, the entire area of ​​the upper section 10a is the main air outlet 131, and the entire area of ​​the lower section 10b is the air inlet 170. While meeting the requirements for air intake and exhaust volume, the volume of the entire casing 100 can be reduced, thereby reducing the overall volume of the cabinet air conditioner and further improving its ease of use.

[0068] In this embodiment, as Figure 6 and Figure 7 As shown, a cylindrical evaporator 800 is provided inside the casing 100. The evaporator 800 is located in the lower cylindrical section 10b, and the first air intake 210 of the first mixed-flow fan 200 is located above the evaporator 800. The arrangement of the evaporator 800 corresponds to the air inlet 170. The first air intake 210 of the first mixed-flow fan 200 is located above the evaporator 800. In use, the first air intake 210 generates an upward suction effect on the space below it. Under the suction effect, the air in the indoor environment can flow into the air duct through the air inlet 170 and flow to the area below the first air intake 210, thereby effectively exchanging heat with the evaporator 800 located in this area. The airflow then enters the first mixed-flow fan 200 through the first air intake 210 and is blown out through the main air outlet 131 or the top air outlet 111, which improves the smoothness of airflow and reduces the occurrence of airflow turning and turbulence, thereby improving the air volume, temperature regulation effect and noise reduction of the cabinet air conditioner.

[0069] In this embodiment, as Figure 6 and Figure 7 As shown, the height extension area of ​​the evaporator 800 corresponds to the height extension area of ​​the air inlet 170. The height of the evaporator 800 is consistent with the height of the air inlet 170 in the lower cylinder section 10b, that is, the bottom end of the evaporator 800 is approximately at the same height as the bottom end of the air inlet 170, and the top end of the evaporator 800 is approximately at the same height as the top end of the air inlet 170. The first air intake 210 of the first mixed flow fan 200 is located above the evaporator 800. In use, the evaporator 800 is almost completely covered by the inside of the air inlet 170. The airflow flowing in through the air inlet 170 can almost entirely flow through the evaporator 800 and exchange heat with it, thereby ensuring that the evaporator 800 fully and sufficiently exchanges heat with the airflow flowing through the air duct, improving the temperature regulation effect of the cabinet air conditioner on the indoor environment, and reducing the occurrence of airflow being blown out without exchanging heat with the evaporator 800.

[0070] When the lower section 10b is cylindrical, it is preferable that, for example... Figure 6 and Figure 7 As shown, the evaporator 800 is an annular cylindrical shape, and the axial direction of the evaporator 800 is consistent with the axial direction of the lower cylinder section 10b.

[0071] In this embodiment, as Figure 6 and Figure 7As shown, the first mixed-flow fan 200 is an annular mixed-flow fan. The first air intake 210 of the first mixed-flow fan 200 faces downward and is connected to the upper port of the evaporator 800. The annular mixed-flow fan has an annular flow channel 330 surrounding its periphery. The first mixed-flow fan 200 is horizontally arranged, and the annular flow channel 330 is approximately coaxial with the evaporator 800. The annular port at the bottom of the annular flow channel 330 serves as its first air intake 210, and the top port serves as its first air exhaust 220. The first air intake 210 is adjacent to and connected to the upper port of the evaporator 800. In use, airflow enters through the air inlet 170 and flows from the outside to the inside of the evaporator 800. After entering the internal space of the cylinder, the air can flow upward and completely into the first air intake 210 under the suction action of the first air intake 210, and then be discharged outward through the first exhaust 220, the main air outlet 131, and the top air outlet 111, thereby ensuring smooth and effective airflow, reducing the occurrence of reduced air volume and noise pollution caused by airflow turbulence in the air duct, and further improving the air volume, temperature regulation effect, quietness and user comfort of the cabinet air conditioner.

[0072] In this embodiment, as Figures 5-7 As shown, an annular partition 123 is provided between the connection between the upper cylinder section 10a and the lower cylinder section 10b and the first mixed-flow fan 200. The first air intake 210 is connected to the internal space of the lower cylinder section 10b, and the first air exhaust 220 of the first mixed-flow fan 200 is connected to the internal space of the upper cylinder section 10a. The annular baffle 123 is approximately a horizontal baffle. The annular baffle 123 is located at the connection between the upper cylinder section 10a and the lower cylinder section 10b, and it acts as a seal and barrier between the housing 100 and the first mixed-flow fan 200, thereby dividing the internal space of the upper cylinder section 10a and the lower cylinder section 10b into upper and lower parts. In use, the first air intake 210 generates an upward suction effect on the internal space of the lower cylinder section 10b. Under the suction effect, the indoor air flows into the annular space of the lower cylinder section 10b through the air inlet 170. Subsequently, the airflow can only flow upward through the first air intake 210 into the first mixed-flow fan 200, and then into the internal space of the upper cylinder section 10a through its first exhaust 220, and then blown outward through the main air outlet 131 or the top air outlet 111.

[0073] The annular baffle 123, in conjunction with the first mixed-flow fan 200, separates the air inlet 170 and the main air outlet 131 on relatively independent sides. This reduces the suction effect of the first air intake 210 on the main air outlet 131, or the blowing effect of the first exhaust 220 on the air inlet 170, as well as the turbulence of the airflow entering the duct between the first mixed-flow fan 200 and the casing 100. This further improves the smoothness and stability of the airflow through the duct, thereby increasing the air volume and temperature regulation effect of the cabinet air conditioner. At the same time, it effectively reduces noise pollution caused by airflow disturbance, improving the quiet operation and user comfort of the cabinet air conditioner.

[0074] Specifically, the annular partition 123 is sandwiched between the upper cylinder section 10a and the lower cylinder section 10b, and extends inward to the first mixed-flow fan 200. Thus, the annular partition 123, the upper cylinder section 10a, and the lower cylinder section 10b are three relatively independent components, which makes them easier to process and assemble, thereby improving the processing and assembly convenience of the cabinet air conditioner.
