Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a vertical air conditioner. Background Technology

[0002] Air conditioners are widely used for indoor temperature regulation. In existing air conditioners, cross-flow fans are generally used as the power source and are placed in the air duct to drive the airflow. However, cross-flow fans are bulky and have a small air volume. At the same time, in existing air conditioners, due to the position of the air inlet and outlet, the airflow enters the air duct through the air inlet and is blown out through the fan and outlet. During this process, the airflow has many turns, resulting in low airflow smoothness, large air volume loss, and significant noise pollution caused by airflow disturbance.

[0003] In summary, existing air conditioners suffer from problems such as low air volume, weak temperature regulation, and poor noise reduction. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical air conditioner to solve the technical problems of existing air conditioners having small air volume, weak temperature regulation effect, and poor noise reduction effect.

[0005] To solve the above problems, this utility model provides a vertical air conditioner, including a housing, the front panel of the housing is provided with a front air outlet, and the back panel of the housing is provided with an air inlet;

[0006] The housing is equipped with a mixed-flow fan, the air inlet of which faces the air inlet and the air outlet of which faces the front air outlet.

[0007] The vertical air conditioner provided by this utility model has an air duct formed inside the shell. A compact, high-volume, and low-noise mixed-flow fan is used inside the air duct as the power source to drive the airflow. While ensuring the air volume and temperature regulation effect of the vertical air conditioner, it can effectively reduce the overall size of the vertical air conditioner, reduce its space occupation, reduce its operating noise, and improve its ease of installation and user comfort.

[0008] Simultaneously, the air inlet, mixed-flow fan, and front air outlet are arranged from back to front, with the mixed-flow fan's suction port facing backward towards the air inlet and its exhaust port facing forward towards the front air outlet. During operation, under the suction action of the mixed-flow fan, indoor air enters the duct from the air inlet, exchanges heat with the evaporator, and then continues forward through the suction port into the mixed-flow fan. Driven by the mixed-flow fan, it then flows forward through the exhaust port to the front air outlet, and is finally blown out through the front air outlet, thus completing the airflow within the duct. On one hand, the mixed-flow fan's suction port corresponds to the air inlet of the casing, and the mixed-flow... The exhaust port of the fan corresponds to the front air outlet of the casing. The air intake port has a smoother airflow and a larger air volume into the air duct through the air inlet. The air outlet has a smoother airflow and a larger air volume into the front through the air outlet. On the other hand, the airflow path through the air duct is generally from back to front, with fewer airflow turns. The airflow through the air duct is smoother, the air volume loss is lower, and the noise pollution caused by airflow disturbance is less. This further improves the air supply effect and temperature regulation effect of the vertical air conditioner, as well as the quiet operation and user comfort of the vertical air conditioner.

[0009] Optionally, the mixed-flow fan has an annular flow channel, the axis of the annular flow channel is consistent with the front-to-back direction, and the annular flow channel opening at the rear end of the annular flow channel serves as the air intake, and the annular flow channel opening at the front end of the annular flow channel serves as the air exhaust.

[0012] Optionally, the partition covers the rear end of the front air outlet and is recessed relative to the front air outlet.

[0013] Optionally, a support frame is provided in the rear air duct, and the mixed-flow fan is connected to the support frame.

Detailed Implementation

[0027] 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.

[0028] This embodiment provides a vertical air conditioner, such as... Figures 1-5 As shown, the device includes a housing 100, a front panel 131 of which has a front air outlet 140, and a back panel 133 of which has an air inlet 150. A mixed-flow fan 200 is provided inside the housing 100, with the air intake 210 of the mixed-flow fan 200 facing the air inlet 150 and the air exhaust 220 of the mixed-flow fan 200 facing the front air outlet 140.

[0029] In the vertical air conditioner provided in this embodiment, the casing 100 forms an air duct 180. A compact, high-volume, and low-noise mixed-flow fan 200 is used in the air duct 180 as the power source to drive the airflow. While ensuring the air volume and temperature regulation effect of the vertical air conditioner, it can effectively reduce the overall volume of the vertical air conditioner, reduce its space occupation, reduce its operating noise, and improve its ease of installation and user comfort.

[0030] Simultaneously, an air inlet 150, a mixed-flow fan 200, and a front air outlet 140 are arranged from back to front, with the air intake 210 of the mixed-flow fan 200 facing backward toward the air inlet 150, and the air exhaust 220 of the mixed-flow fan 200 facing forward toward the front air outlet 140. During operation, under the suction action of the mixed-flow fan 200, indoor air enters the air duct 180 from the air inlet 150, exchanges heat with the evaporator 500, and continues forward through the air intake 210 into the mixed-flow fan 200. Driven by the mixed-flow fan 200, it flows forward through the air exhaust 220 to the front air outlet 140, and is then blown out forward through the front air outlet 140, thus completing the airflow within the air duct 180. On one hand, the air intake 210 of the mixed-flow fan 200... The air inlet 150 of the housing 100 corresponds to the air inlet 150 of the housing 100, and the air outlet 220 of the mixed flow fan 200 corresponds to the air outlet 140 of the housing 100. The air inlet 210 has a smoother air intake and a larger air volume into the air duct 180 through the air inlet 150, and the air outlet 220 has a smoother air supply and a larger air supply volume into the front through the air outlet 140. On the other hand, the airflow path through the air duct 180 is generally from back to front, with fewer airflow turns. The airflow through the air duct 180 is smoother, the air supply loss is lower, and the noise pollution caused by airflow disturbance is less. This further improves the air supply effect and temperature regulation effect of the vertical air conditioner, and also improves the quiet operation and user comfort of the vertical air conditioner.

[0031] Specifically, such as Figures 1-5 As shown, the housing 100 includes a top plate 110, a bottom plate 120, and a side plate 130 surrounding the two. The side plate 130 specifically includes a front panel 131 located on the front side, a back plate 133 located on the rear side, and a side plate 132 connecting the two. The side plate 132 consists of two pieces, which are located at the two ends of the left-right Y direction. The mixed flow fan 200 is specifically an annular mixed flow fan, which is surrounded by an annular flow channel 230. The axis of the annular flow channel 230 is consistent with the front-back X direction. The annular flow channel opening at the front end of the annular flow channel 230 serves as an exhaust port 220, and the annular flow channel opening at the rear end serves as an intake port 210.

[0032] Specifically, such as Figure 2 As shown, the 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 in 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 accelerating exhaust port 220. A ring of ribs 270 arranged at intervals along its circumference is also provided at the exhaust port 220 of the mixed-flow fan 110 to achieve spiral high-speed airflow.

[0033] In this embodiment, as Figure 3 and Figure 5As shown, the front panel 131 includes a first panel area 131a and a second panel area 131b from top to bottom. The extension height of the second panel area 131b is 0.7 to 0.9 of the extension height of the front panel 131, and the opening of the second panel area 131b forms a front air outlet 140. The air inlet 150 is located on the back panel 133, without occupying the panel area of ​​the front panel 131. The first panel area 131a near the top of the front panel 131 can serve as a control panel for user operation. The area of ​​the front panel 131 below the first panel area 131a is opened to form a large-area open air inlet 150. Specifically, the width of the air inlet 150 is approximately the same as that of the front panel 131, and the height of the air inlet 150 is approximately 0.7 to 0.9 times the overall height of the front panel 131 and the housing 100. This increases the front air outlet area of ​​the vertical air conditioner, thereby further improving the air outlet smoothness and air volume of the vertical air conditioner. During operation, the airflow blown out through the front air outlet 140 has a larger range, which can quickly achieve temperature regulation of the indoor environment, and the temperature regulation uniformity is higher, resulting in higher user comfort.

[0034] In this embodiment, there are at least two mixed-flow fans 200, and each mixed-flow fan 200 is distributed along the Z-direction of the height. The front air outlet 140 has a large extension height and air outlet area, so at least two mixed-flow fans 200 are provided. Each mixed-flow fan 200 is located in the area of ​​the front air outlet 140 and is arranged at intervals along the Z-direction of the height. This allows the entire air outlet area of ​​the front air outlet 140 to effectively outlet air without increasing the volume of the housing 100, thereby further increasing the overall air volume and temperature regulation effect of the vertical air conditioner.

[0035] like Figures 2-6 As shown, there are two mixed-flow fans 200, both of which are located in the area of ​​the front air outlet 140 and are arranged at intervals in the vertical direction.

[0036] In this embodiment, a support frame 190 is provided inside the housing 100, and the mixed-flow fan 200 is connected to the support frame 190. The support frame 190 can fix the position of the mixed-flow fan 200 in the air duct 180, and at the same time support the mixed-flow fan 200 upward to ensure the positional stability of the mixed-flow fan 200.

[0037] In this embodiment, as Figure 1 and Figure 2As shown, a zero-air deflector 300 is installed at the front air outlet 140. The zero-air deflector 300 is configured to disperse the airflow. The zero-air deflector 300 is provided with multiple zero-air holes or multiple impellers and other airflow dispersion structures 310. When the airflow blown by the mixed-flow fan 200 flows through the airflow dispersion structure 310, it can be dispersed into air masses with lower flow velocity and higher noise reduction effect, and then blown forward. While achieving the function of regulating the indoor ambient temperature, it reduces the unpleasant experience caused by the direct airflow from the front of the vertical air conditioner to the user, and further improves the quietness of the vertical air conditioner and the comfort of use.

[0038] The zero-airflow panel 300 can be sized to match the front air outlet 140 and be embedded in the front air outlet 140 to shield it; or, the zero-airflow panel 300 can be slightly larger than the front air outlet 140 and abut against the front end of the front air outlet 140, completely covering it to shield it.

[0039] In this embodiment, as Figures 2-5 As shown, the housing 100 has a partition 170 inside, which is located between the front air outlet 140 and the back plate 133. The partition 170 and the front air outlet 140 form a front air duct 181, and the partition 170 and the back plate 133 form a rear air duct 182. The partition 170 is provided with a connection hole 171. The mixed flow fan 200 is housed in the rear air duct 182, and the front end of the mixed flow fan 200 is inserted into the connection hole 171. The exhaust port 220 extends into the front air duct 181. The partition 170 divides the air duct 180 inside the housing 100 into two relatively independent cavities, namely the front air duct 181, the cavity between the front panel 131, the zero-air plate 300 and the partition 170, and the rear air duct 182, the cavity between the partition 170 and the back panel 133. During operation, indoor air flows forward into the rear air duct 182 through the rear air inlet 150, and then enters the mixed flow fan 200 through the air intake 210. Subsequently, it is blown into the front air duct 181 through the exhaust 220 at its front end. The airflow entering the front air duct 181 can diffuse and flow to the surrounding area under the resistance of the airflow dispersion structure 310, and is blown outward through the airflow dispersion structure 310 in that area.

[0040] In this embodiment, the air duct 180 is divided into a front air duct 181 and a rear air duct 182 by a partition 170. On the one hand, the intake airflow and exhaust airflow of the mixed flow fan 200 can be separated into the rear air duct 182 and the front air duct 181 respectively, thereby reducing the disturbance between the two airflows, ensuring the smoothness of airflow, reducing noise pollution caused by airflow disturbance, and further improving the air volume and quiet operation of the vertical air conditioner. On the other hand, the airflow blown out by the mixed flow fan 200 enters the smaller front air duct 181 and can flow and diffuse quickly in the front air duct 181, thereby blowing forward more evenly through the entire area of ​​the zero air plate 300, ensuring the effective use of the entire area of ​​the zero air plate 300, the smooth blowing of airflow, and improving the uniformity of air outlet.

[0041] Specifically, in this embodiment, as Figure 5 As shown, the partition 170 covers the rear end of the front air outlet 140 and is recessed relative to the front air outlet 140. The partition 170 and the zero-air plate 300 cover the front and rear sides of the front air outlet 140 respectively. The area of ​​the front air duct 181 formed by the two is consistent with the area of ​​the front air outlet 140, and the front and rear thickness of the front air duct 181 is smaller, thereby further reducing the spatial volume of the front air duct 181 and reducing the corner space formed between the front air duct 181 and the front panel 131. Correspondingly, it further improves the flow and diffusion of airflow entering the front air duct 181, improves the comprehensiveness and uniformity of the outward blowing of the zero-air plate 300, and at the same time reduces the air volume loss and noise pollution caused by the flow of air in the edge corner space of the front air duct 181, thereby further ensuring the air volume and quiet operation of the vertical air conditioner.

[0042] Specifically, along the front-to-back X direction, the thickness of the front air duct 181 is 0.15 to 0.25 times the thickness of the rear air duct 182.

[0043] In this embodiment, as Figure 2 , Figure 4 and Figure 6 As shown, the housing 100 is provided with a drive structure 400, which is connected to the zero-air vane 300. The drive structure 400 is configured to: drive the zero-air vane 300 forward to form an annular side air outlet 160 with the edge of the front air outlet 140; or drive the zero-air vane 300 backward to block the front air outlet 140. The zero-air vane 300 can move back and forth under the drive of the drive structure 400, and by varying its relative position to the front air outlet 140, it forms different airflow patterns, allowing the vertical air conditioner to enter different temperature control modes. Specifically, the vertical air conditioner has a zero-airflow mode and an annular airflow mode, wherein:

[0044] In zero-wind mode, such as Figure 1 and Figure 2As shown, the zero-airflow plate 300 blocks the front air outlet 140. When the user needs large-area, high-comfort, and rapid temperature adjustment, the drive component can be controlled to drive the zero-airflow plate 300 to move backward and embed itself in or abut against the front end of the front air outlet 140 to completely block the front air outlet 140. During operation, the vertical air conditioner enters the zero-airflow mode. After the airflow enters the front air duct 181 through the exhaust port 220, it can only be dispersed by the airflow dispersion structure 310 of the zero-airflow plate 300 before being blown forward with a large area and low flow rate (only the flow direction of the local airflow is shown in the figure), thereby achieving rapid temperature adjustment and ensuring the user's physical comfort.

[0045] This zero-wind mode is particularly suitable for cooling regulation, and can quickly cool a large area in front of the floor air conditioner.

[0046] In the circular air outlet mode, such as Figure 3 and Figure 4 As shown, the zero-wind plate 300 is located in front of the front air outlet 140 and forms a ring-shaped side air outlet 160 with the edge of the front air outlet 140. When a user is in front of the vertical air conditioner and does not want to be blown by the airflow, the drive component can be controlled to drive the zero-air plate 300 forward away from the front air outlet 140 until the zero-air plate 300 and the front air outlet 140 reach a preset distance. Then, the outer periphery of the zero-air plate 300 and the outer periphery of the front air outlet 140 can form a ring-shaped side air outlet 160. During operation, the vertical air conditioner enters the ring-shaped air outlet mode. After the airflow enters the front air duct 181 through the exhaust port 220, since the airflow dispersion structure 310 in the zero-air plate 300 has a greater air resistance than the side air outlet 160, the airflow entering the front air duct 181 is preferentially blown out to the corresponding side through the side air outlet 160 (only the flow direction of the local airflow is shown in the figure). This forms a ring-shaped three-dimensional air outlet area on the side of the vertical air conditioner, which reduces the forward blowing area of ​​the airflow while achieving the adjustment of the indoor ambient temperature.

[0047] Specifically, in this embodiment, as Figure 2 , Figure 4 and Figure 6As shown, the zero-wind plate 300 is slidably connected to the housing 100 in the X direction along the front-back direction, and the rear side of the zero-wind plate 300 is provided with a rack 320 extending backward; the drive structure 400 includes a rotary drive member 410 and a drive gear 420 that is connected to the rotary drive member 410, and the drive gear 420 meshes with the rack 320. In use, the rotary drive 410 drives the drive gear 420 to rotate in the first direction, thereby driving the rack 320 to move the zero-air vane 300 backward toward the front air outlet 140 until the zero-air vane 300 blocks the front air outlet 140. When the zero-air vane 300 is in this position, the vertical air conditioner can be in the off, standby, or zero-air mode. Alternatively, the rotary drive 410 drives the drive gear 420 to rotate in the second direction opposite to the first direction, thereby driving the rack 320 to move the zero-air vane 300 forward away from the front air outlet 140 until a preset distance is reached between the zero-air vane 300 and the front air outlet 140, forming a side air outlet 160 between their outer edges. When the zero-air vane 300 is in this position, the vertical air conditioner is in the circumferential air outlet mode.

[0048] The drive structure 400 and rack 320 can be two or more sets, and are arranged at intervals along the height direction Z of the zero wind plate 300. In use, multiple sets of drive structures 400 and corresponding racks 320 cooperate to synchronously drive different positions of the zero wind plate 300 in the height direction Z, so as to improve the stability of the drive of the zero wind plate 300.

[0049] like Figure 2 and Figure 4 As shown, the partition 170 is provided with a insertion hole 172, and the rack 320 is slidably inserted into the insertion hole 172 in the X direction along the front-back direction; the drive structure 400 is installed in the rear air duct 182, and its drive gear 420 meshes with the part of the rack 320 that extends rearward into the rear air duct 182.

[0050] In this embodiment, as Figure 3 and Figure 5As shown, the back panel 133 includes a first plate 133a, a second plate 133b, and a third plate 133c in sequence along the circumference of the housing 100. The second plate 133b is parallel to the front air outlet 140, and the first plate 133a and the third plate 133c extend from back to front away from each other. The air inlet 150 includes a first side air outlet provided on the first plate 133a, a rear air outlet provided on the second plate 133b, and a second side air outlet provided on the third plate 133c. The horizontal cross-sectional profile of the area enclosed by the back panel 133 is approximately trapezoidal, and the area where the air inlet 150 is located simultaneously covers the first plate 133a, the second plate 133b, and the third plate 133c of the back panel 133. This gives the vertical air conditioner a large air inlet 150, thereby ensuring its air intake and delivery volume and ensuring the temperature regulation effect of the indoor environment. At the same time, when the user needs to place the vertical air conditioner against a wall or in a corner, since the extension directions of the first plate 133a, the second plate 133b, and the third plate 133c are different, even if one or even two of them are blocked by a wall or surrounding objects, there is still an unobstructed air intake area, which can ensure the normal use of the vertical air conditioner, thereby reducing the limitation on the location of use of the vertical air conditioner and improving the applicability of the vertical air conditioner.
