[0040] Figure 1 is a schematic structural diagram of a wind shielding member shielding an air inlet according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 5 The embodiment of the utility model provides a vertical indoor unit 100, including a casing 10, an air guide 20 and a wind shield 40. The casing 10 defines a main air duct 110 and forms an air outlet connected to the outlet of the main air duct 110. The air guide 20 defines a sub-air duct 30, and the sub-air duct 30 extends in the axial direction of the air outlet. The air guide 20 is configured to move in the axial direction of the air outlet so that an air outlet gap is defined between the air outlet portion 250 of the air guide 20 and the air outlet of the casing 10, or they are interlocked to prevent air from flowing out. The air guide 20 forms an air inlet 280 located on the air duct wall of the sub-air duct 30, and the air inlet 280 is communicated with the main air duct 110. The wind shield 40 is connected to the guide member along the axial movement of the air outlet, and the guide member is connected to the housing 10, so that the guide member defines a movement stroke, in at least one stroke position, the wind shield 40 blocks the air inlet 280 of the air guide member 20, blocking the main air duct 110 and the sub-air duct 30. In at least another stroke position, the wind shield 40 opens part or all of the air inlet 280 of the air guide member 20, connecting the main air duct 110 and the sub-air duct 30.

[0041] In the present embodiment, the air guide member 20 can move axially. When the air guide member 20 moves in a direction away from the air outlet, the air outlet portion 250 of the air guide member 20 is interlocked with the air outlet, and the heat exchange air is blown out from the air outlet portion 250 of the air guide member 20. The air outlet is more concentrated, thereby increasing the air outlet distance. When the air guide member 20 moves in a direction close to the air outlet, the air outlet portion 250 of the air guide member 20 forms an air outlet gap with the air outlet, and the heat exchange air is blown out from the air outlet gap. The air outlet is more dispersed, the air outlet distance is short, and the air outlet is more uniform. In addition, the surrounding wall of the air guide member 20 has an air inlet 280, and the axial movement of the wind shield member 40 can block, partially block, or open the air inlet 280. By changing the opening degree of the air inlet 280, the air intake at the air inlet 280 is adjusted, thereby changing the air outlet.

[0042] By moving the air guide 20, the heat exchange air is blown out from the air outlet or the air outlet gap, and the air supply distance of the vertical indoor unit 100 is adjusted, so that the heat exchange air can be blown to the indoor space near and far from the vertical indoor unit 100, thereby adjusting the temperature of the indoor space near and far from the vertical indoor unit 100. The air guide 20 can quickly adjust the temperature of the indoor space, make the indoor temperature evenly distributed, improve the efficiency of temperature regulation, solve the problem of uneven temperature regulation efficiency, and thus improve the user experience. In addition, by moving the wind shield 40, the opening degree of the air inlet 280 is changed to adjust the air outlet of the vertical indoor unit 100, thereby adjusting the indoor temperature, making the indoor temperature uniform, and improving the user experience.

[0043] In some embodiments of the present invention, the vertical indoor unit 100 further includes a limiting member, which is fixedly connected to the casing 10 to limit the air guide member 20 from moving along the limiting member.

[0044] In the present embodiment, during the axial movement of the air guide member 20, the limit member radially limits the air guide member 20, so that the axial constraint of the air guide member 20 during the movement of the air guide member 20 is more precise, preventing the air guide member 20 from shaking up and down and left and right, and avoiding eccentric shaking or jamming of the air guide member 20 during the movement, making the movement of the air guide member 20 smoother and improving the user experience.

[0045] In some embodiments of the present invention, Figures 1 to 3 As shown, the limiting member includes at least two first guide rods 510, which extend along the axial direction of the air guide member 20. The first guide rods 510 are arranged around the circumference of the air guide member 20 so that the first guide rods 510 support the axial movement of the air guide member 20.

[0046] In this embodiment, both ends of the first guide rod 510 are mounted on the housing 10, and at least two first guide rods 510 are evenly arranged around the air guide member 20 to support the air guide member 20 and prevent the air guide member 20 from eccentrically shaking or getting stuck. Preferably, the stopper includes three first guide rods 510.

[0047] In some embodiments of the present invention, the vertical indoor unit 100 further includes a limiting member, which is fixedly connected to the casing 10 to limit the wind shielding member 40 from moving along the limiting member.

[0048] Since the windshield 40 has a relatively large stroke, it is easy for the windshield 40 to get stuck during the movement. In this embodiment, during the axial movement of the windshield 40, the limiter limits the windshield 40 in the radial direction, so that the limiter can more accurately constrain the axial direction of the windshield 40 during the movement, preventing the windshield 40 from shaking up and down or left and right, and avoiding eccentric shaking or getting stuck during the movement of the windshield 40, so that the movement of the windshield 40 is smoother, and the user experience is improved.

[0049] In some embodiments of the present invention, Figures 1 to 3 As shown, the limiting member includes at least two second guide rods 520, which extend along the axial direction of the wind shield 40. At least two second guide rods 520 are arranged around the circumference of the wind shield 40 so that the second guide rods 520 support the axial movement of the wind shield 40.

[0050] In this embodiment, both ends of the second guide rod 520 are mounted on the housing 10. When the wind shield 40 is at the air inlet 280 of the wind guide 20, the wind shield 40 is located inside the wind guide 20, and therefore, the second guide rod 520 is located inside the wind guide 20. At least two second guide rods 520 are evenly arranged around the wind shield 40 in the circumferential direction to support the wind shield 40 and prevent the wind shield 40 from eccentrically shaking or getting stuck. Preferably, the limiting member includes three second guide rods 520.

[0051] In some embodiments of the present invention, the vertical indoor unit 100 further includes a limiting member, which is fixedly connected to the casing 10 to limit the air guide member 20 and the air shield member 40 to move along the limiting member.

[0052] In the present embodiment, during the axial movement of the air guide member 20 and the wind shield member 40, the limit member radially limits the air guide member 20 and the wind shield member 40, so that the axial constraint of the air guide member 20 and the wind shield member 40 during the movement of the limit member is more precise, preventing the air guide member 20 and the wind shield member 40 from shaking up and down and left and right, and avoiding eccentric shaking or jamming of the air guide member 20 and the wind shield member 40 during the movement, making the movement of the air guide member 20 and the wind shield member 40 smoother, thereby improving the user experience.

[0053] In some embodiments of the present invention, Figures 1 to 3As shown, the limiting member includes at least two first guide rods 510 and at least two second guide rods 520, the first guide rods 510 extending along the axial direction of the wind guide member 20, and the first guide rods 510 are arranged around the circumference of the wind guide member 20, so that the first guide rods 510 support the axial movement of the wind guide member 20. The second guide rods 520 extend along the axial direction of the wind shield member 40, and at least two second guide rods 520 are arranged around the circumference of the wind shield member 40, so that the second guide rods 520 support the axial movement of the wind shield member 40.

[0054] In some alternative embodiments of the present invention, the limiting member includes a slide rail and a slider. The inner wall of the casing 10 is provided with a plurality of slide rails extending along the axial direction of the air outlet, and the air guide 20 and the air shield 40 are provided with a plurality of protruding sliders, and the sliders move in the slide rails to prevent the air guide 20 and the air shield 40 from eccentrically shaking during movement, which may cause the air guide 20 or get stuck. The slide rails and the sliders are arranged in a one-to-one correspondence. Alternatively, slide rails are arranged on the outer wall surface of the air guide 20 and the air shield 40, and sliders are arranged on the inner wall surface of the casing 10, which can also prevent the air guide 20 and the air shield 40 from eccentrically shaking or getting stuck during movement.

[0055] In some embodiments of the present invention, Figures 1 to 3 As shown, the peripheral wall of the wind guide 20 extends outwardly in the circumferential direction to form a first connection portion 210 and a second connection portion 220, and the first connection portion 210 and the second connection portion 220 are provided with connection holes that allow the first guide rod 510 to pass through. The end of the wind shield 40 close to the air outlet extends outwardly to form a third connection portion 410, and the peripheral wall of the wind shield 40 extends outwardly in the circumferential direction to form a fourth connection portion 420, and the fourth connection portion 420 is far from the end of the air outlet. The third connection portion 410 and the fourth connection portion 420 are provided with connection holes that allow the second guide rod 520 to pass through.

[0056] In this embodiment, the wind guide member 20 and the wind shield member 40 are provided with connecting holes, the wind guide member 20 is connected to the first guide rod 510 through the connecting hole, and the wind shield member 40 is connected to the second guide rod 520 through the connecting hole, and the connecting method is simple and convenient.

[0057] In some embodiments of the utility model, one end of the air guide 20 close to the air outlet 250 extends inward to form a first extension portion, and when the wind shield 40 moves along the air outlet, the third connection portion 410 pushes the first extension portion to define an air outlet gap between the air outlet 250 of the air guide 20 and the air outlet. Alternatively, one end of the air guide 20 away from the air outlet 250 extends inward to form a second extension portion, and when the wind shield 40 moves along the air outlet, the third connection portion 410 drives the second extension portion to make the air outlet 250 of the air guide 20 and the air outlet fit together to prevent air from flowing out.

[0058] In this embodiment, the axial movement of the wind shield 40 drives the axial movement of the air guide member 20, so that the air guide member 20 and the air outlet define an air outlet gap or fit together, thereby changing the air outlet position and air outlet distance of the heat exchange air to enhance the user experience.

[0059] In some embodiments of the utility model, the vertical indoor unit 100 includes a stop wall, and the stop wall is located between the fourth connection part 420 and the second extension part. The stop wall is configured to abut against the fourth connection part 420 when an air outlet gap is defined between the air outlet part 250 of the air guide member 20 and the air outlet to prevent the air shielding member 40 from continuing to move along the air outlet. Alternatively, the stop wall is configured to abut against the second extension part when the air outlet part 250 of the air guide member 20 and the air outlet are engaged with each other to prevent the air guide member 20 from continuing to move along the air outlet.

[0060] In this embodiment, when the wind shielding member 40 moves to the extreme positions at both ends, the stop wall abuts against the fourth connecting portion 420 or the second extension portion to avoid excessive movement of the air guide member 20, thereby ensuring that the air guide member 20 accurately reaches the position that defines the air outlet gap between the air outlets or the position that is mutually interlocked with the air outlets.

[0061] In some embodiments of the present invention, Figure 3 As shown, the wind shield 40 has a channel arranged along the axial direction, so that when the wind shield 40 blocks the air inlet 280 of the air guide 20, the heat exchange wind enters the sub-air duct 30 from the wind shield 40.

[0062] In this embodiment, when the wind shield 40 blocks the air inlet 280 of the air guide 20, the heat exchange air in the main air duct 110 can enter the sub-air duct 30 through the channel of the wind shield 40. When the wind shield 40 opens the air inlet 280 of the air guide 20, the heat exchange air in the main air duct 110 can enter the sub-air duct 30 through the air inlet 280, thereby realizing the axial and radial air supply of the vertical indoor unit 100.

[0063] In some embodiments of the present invention, Figure 1 and 3 As shown, the guide member includes a rack portion 710, and the rack portion 710 is fixedly arranged at the bottom of the wind shield 40 along the axial direction of the wind shield 40. The vertical indoor unit 100 also includes a driving motor 80 and a gear 720 connected to the motor shaft of the driving motor 80. The driving motor 80 and the gear 720 are fixedly arranged on the housing 10, and the gear 720 is meshed with the rack. The driving motor 80 is configured to drive the motor 80 shaft to rotate so that the gear 720 drives the wind shield 40 to move along the axial direction of the air outlet.

[0064] In this embodiment, the driving motor 80 is turned on, driving the motor shaft to rotate, and the motor shaft drives the gear 720 to rotate, so that the rack moves along the axial direction of the windshield 40, thereby driving the axial movement of the windshield 40. The gear 720 rack transmission works smoothly, has high reliability, can ensure a constant transmission ratio, and the windshield 40 maintains a uniform speed during the movement process, so that the air intake and air outlet distance are adjusted more evenly, thereby improving the user experience.

[0065] In some embodiments of the present invention, Figures 1 to 5 As shown, the air outlet portion 250 is trumpet-shaped, and the large-diameter end of the air outlet portion 250 faces the direction of the air outlet. The air guide 20 also includes a plurality of body portions 260 and a connecting member 270. The plurality of body portions 260 are connected to the air outlet portion 250 along the axial direction of the air outlet, and the body portion 260 is trumpet-shaped in the opposite direction of the air outlet portion 250; the plurality of body portions 260 are arranged at intervals along the axial direction of the air outlet, and any two adjacent body portions 260 and any two adjacent body portions 260 and air outlet portions 250 form an air inlet 280. The plurality of connecting members 270 are evenly distributed along the periphery of the plurality of body portions 260 to connect the plurality of body portions 260 and the air outlet portion 250 together.

[0066] In this embodiment, the end of the air outlet 250 close to the air outlet is a large-diameter end. When the air is discharged, the air outlet angle is larger, and the heat exchange air distribution area is larger, which improves the indoor temperature adjustment rate and thus improves the user experience. The large-diameter end of the main body 260 is at the end away from the air outlet. When the heat exchange air enters from the air inlet 280, it flows along the wall surface of the main body 260 toward the air outlet, playing a role in guiding the air.

[0067] The utility model further provides an air conditioner, comprising a vertical indoor unit 100 as in any one of the above embodiments.

[0068] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
