Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to a vertical air conditioner with a mixing and equalizing airflow function. Background Technology

[0002] Currently, with the widespread use of air conditioning and the promotion of health concepts, users have increasingly higher requirements for the comfort of air conditioning airflow. Traditional air conditioners deliver strong airflow, blowing cold air directly, resulting in a poor user experience and frequent air conditioning-related illnesses. More users expect the air from their air conditioners to be gentle, cool but not cold. Current technologies include using air vents to block the air outlet, and designs that incorporate structures on the air vents to disperse the airflow. All these solutions aim to reduce the feeling of coldness from the airflow directly hitting the user. However, the main purpose of these existing technologies is to prevent the airflow from blowing directly on the person by creating obstacles in the airflow field, thus all of which have some impact on the airflow, such as affecting air volume and generating noise. Summary of the Invention

[0003] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0004] This disclosure provides a vertical air conditioner with a mixing and equalizing function to solve the problem of direct cold air blowing without affecting the airflow.

[0009] The heat exchanger is located inside the housing;

[0010] The first fan is positioned near the first air inlet, the second fan is positioned near the second air inlet, and the heat exchanger is positioned between the first fan and the air outlet, forming a first airflow duct from the first air inlet through the heat exchanger to the air outlet; the second air inlet and the second fan are positioned away from the heat exchanger, forming a second airflow duct from the second air inlet to the air outlet without passing through the heat exchanger.

[0011] Optionally, the vertical air conditioner with mixing and equalizing function of the present invention further includes: a second fan, which is located near the second air inlet and away from the heat exchanger.

[0012] Optionally, the vertical air conditioner with mixing and equalizing air function of the present invention further includes: an air damper disposed between the second air inlet and the air outlet, the air damper being switchable between an open position and a closed position; when the air damper is in the open position, the second air duct is open; when the air damper is in the closed position, the second air duct is closed.

[0013] Optionally, when the damper is in the closed position, the first and second drainage ducts are connected near the damper; when the damper is in the open position, the first and second drainage ducts are not connected.

[0014] Optionally, the vertical air conditioner has a mixed airflow mode and a normal cooling mode. When in the mixed airflow mode, the damper is in the open position; when in the normal cooling mode, the damper is in the closed position.

[0015] Optionally, the vertical air conditioner with mixing and equalizing air function of the present invention further includes: a drive mechanism, the output end of which is connected to the damper, for driving the damper to switch between an open position and a closed position.

[0016] Optionally, the vertical air conditioner with mixing and uniform air function of the present invention further includes: an air guide component located inside the casing near the air outlet and configured to match the shape of the air outlet, wherein an air guide cavity is provided inside the air guide component, and the air outlet ends of the first air duct and the second air duct are respectively connected to the air guide cavity.

[0017] Optionally, the second air duct includes a guide section that extends from the exhaust port of the second fan to the outlet port.

[0019] Optionally, the first air inlet and the first fan are located below the heat exchanger, and the second air inlet, the second fan, and the air outlet are located above the heat exchanger.

[0020] The vertical air conditioner with mixing and uniform airflow function provided in this embodiment establishes a channel through which the fan directly draws in airflow / indoor air from the external indoor environment. This portion of the airflow / indoor air does not pass through the heat exchanger and is fully mixed and uniformly with the heat exchange air that enters from the first air inlet and has undergone heat exchange in the heat exchanger. It is then blown out from the air outlet as the fan operates, making the airflow gentler, cool but not cold, and improving comfort.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0041] Combination Figure 1-7 As shown, this embodiment of the present disclosure provides a vertical air conditioner, including: a casing 1, which is provided with a first air inlet 11, a second air inlet 12 and an air outlet 13; a first fan 21 located inside the casing 1; and a heat exchanger 3 located inside the casing 1; wherein, the first fan 21 is located near the first air inlet 11, and the heat exchanger 3 is located between the first fan 21 and the air outlet 13, forming a first airflow duct (heat exchange airflow duct) from the first air inlet 11 through the heat exchanger 3 to the air outlet 13; the second air inlet 12 is located away from the heat exchanger 3, forming a second airflow duct (non-heat exchange airflow duct) from the second air inlet 12 to the air outlet 13 without passing through the heat exchanger 3.

[0042] By setting up an independent second air duct, a portion of the indoor air is driven by the second fan 22 and enters the duct through the second air inlet 12. Without passing through the heat exchanger 3, it mixes with the heat exchange air that flows through the heat exchanger 3 from the first air inlet 11 driven by the first fan 21 near the air outlet 13 to form mixed air, which is then blown out through the air outlet 13, thus ensuring that the blown air is softer and the comfort is improved.

[0043] Optionally, the vertical air conditioner also includes a second fan 22, located near the second air inlet 12 and away from the heat exchanger 3.

[0044] By setting up a second fan, it is possible to ensure that the indoor air / non-heat exchange air entering the second air intake duct / non-heat exchange air intake duct through the second air inlet 12 meets the required flow rate, thereby improving the effect of mixing and uniform airflow.

[0045] Optionally, the vertical air conditioner also includes a damper 4, which is disposed between the second air inlet 12 and the air outlet 13. The damper 4 can switch between an open position and a closed position. When the damper 4 is in the open position, the second air duct is open; when the damper 4 is in the closed position, the second air duct is closed.

[0046] Combination Figure 3 and Figure 4 As shown, the damper 4 can be installed between the second air inlet 12 and the second fan 22.

[0047] Optionally, when the damper 4 is in the closed position, the first and second drainage ducts are connected near the damper 4; when the damper 4 is in the open position, the first and second drainage ducts are not connected.

[0048] Combination Figure 4 As shown, when the damper 4 is in the closed / vertical position, the portion from the second air inlet 12 to the damper 4 is blocked, thus isolating it from other parts inside the casing 1. Correspondingly, when the damper 4 is in the open / horizontal position, the heat exchange air entering the casing 1 from the first air inlet 11 and flowing through the heat exchanger 3 can enter the second air duct through the opening at the open / horizontal position of the damper, and then flow to the air outlet 13 via the second fan 22.

[0049] Combination Figure 5 As shown, when damper 4 is in the open / horizontal position, the second drainage duct / non-heat exchange air drainage duct is open, and damper 4 itself constitutes part of the second drainage duct (lower base plate). Correspondingly, since damper 4 is in the horizontal position, the heat exchange air flowing through heat exchanger 3 cannot enter the second drainage duct / non-heat exchange air drainage duct through this position, thus isolating the second drainage duct / non-heat exchange air drainage duct from the first drainage duct / heat exchange air drainage duct. The second drainage duct / non-heat exchange air drainage duct forms a closed channel structure except for the openings at both ends. This arrangement ensures that the heat exchange air flowing through heat exchanger 3 does not mix with the indoor air in the second drainage duct prematurely, thereby guaranteeing the flow rate of the indoor air that eventually mixes with the heat exchange air.

[0050] Optionally, the vertical air conditioner has a mixed airflow mode and a normal cooling mode. When in the mixed airflow mode, the damper 4 is in the open position (in conjunction with...). Figure 5 (as shown); when in normal cooling mode, damper 4 is in the closed position (in conjunction with...). Figure 4 (As shown).

[0051] By configuring two operating modes in the vertical air conditioner and setting a damper 4 between the second air inlet 12 and the air outlet 13, users can choose to use the mixed airflow mode or the regular cooling mode according to the indoor environment and their own needs, thereby meeting different user requirements.

[0052] Furthermore, the mixed airflow mode can be set with multiple speed settings. Correspondingly, the second fan 22 can be an adjustable speed fan. By switching the operating mode of the second fan 22, the flow rate of indoor air / heat exchange air in the second air intake duct can be adjusted to better meet the user's needs. When the vertical air conditioner is in the normal cooling mode, the second fan 22 can be turned off to save electricity.

[0053] Optionally, the vertical air conditioner also includes a drive mechanism, the output of which is connected to the damper 4 for driving the damper 4 to switch between an open position and a closed position.

[0054] The drive mechanism can be a stepper motor / pulse motor 5, whose output shaft is connected to the pivot of the damper 4.

[0055] The stepper motor / pulse motor 5 can be set to drive the damper 4 to open when the vertical air conditioner switches from the normal cooling mode to the mixed airflow mode, so that the indoor air enters the second airflow duct; and when the vertical air conditioner switches from the mixed airflow mode to the normal cooling mode, it reverses to drive the damper 4 to close, thereby preventing the indoor air from entering the second airflow duct.

[0056] Optionally, the vertical air conditioner also includes an air guide 6, located inside the casing 1 near the air outlet 13 and configured to match the shape of the air outlet 13. An air guide cavity is provided inside the air guide 6, and the air outlet ends of the first and second air guide ducts are respectively connected to the air guide cavity.

[0057] When the vertical air conditioner is in the mixed airflow mode, the heat exchange air from the first airflow duct and the indoor air from the second airflow duct can be fully mixed in the airflow cavity constructed by the air guide 6, and the mixed air is blown into the indoor space through the air outlet.

[0058] Optionally, the second air duct includes a guide section 7 that extends from the exhaust port of the second fan 22 to the outlet 13.

[0059] Furthermore, the guide section 7 is configured to gradually decrease in the radial direction and gradually increase in the circumferential direction from the exhaust port of the second fan 22 to the outlet 13.

[0060] Combination Figures 3 to 6 As shown, the air outlet 13 of this vertical air conditioner has a roughly circular (or annular) structure, and correspondingly, the air guide 6 has a roughly annular structure. The guide section 7 of the second air duct is designed to gradually narrow in the radial direction, which facilitates the rapid flow of indoor air into the air guide 6 and mixing with the heat exchange air. Furthermore, combined with... Figures 3 to 6 As shown, the upper wall of the guide section 7 is configured to extend downwards from the exhaust port of the second fan 22, causing the airflow direction of the indoor air / non-heat exchange air flowing out of the guide section 7 to be inclined downwards, which helps to mix with the heat exchange air flowing through the heat exchanger 3 below; and the guide section 7 is configured to gradually expand in the circumferential direction, such as Figure 6 and Figure 8As shown, this arrangement expands the mixing area between indoor air / non-heat exchange air and heat exchange air flowing through heat exchanger 3 in the air guide 6, which is beneficial for thorough mixing. It should be noted that the circumferential expansion dimension of the guide section 7 can be adjusted according to the mixing effect requirements and the airflow rate. For example, the outlet end of the guide section 7 (i.e., the outlet end of the second air duct) can be a fan shape concentric with the air outlet 13, or even a ring-shaped outlet forming around the entire circumference of the guide 6. Furthermore, in conjunction with... Figures 2 to 5 As shown, the outlet of the guide section 7 does not face directly toward the air outlet 13 of the casing, but rather toward the area radially outward of the air outlet 13 (the area above the air outlet 13), thereby preventing indoor air / non-heat exchange air from flowing directly out of the air outlet 13 without mixing with the heat exchange air. That is, the size of the air outlet 13 is smaller than the size of the outlet end of the first guide duct, and the outlet end of the second guide duct is located outside the outlet end of the first guide duct, ensuring that the air from the first guide duct and the second guide duct is mixed before being discharged through the air outlet.

[0061] Furthermore, combined Figures 2 to 6 as well as Figure 8 As shown, the inner wall of the air guide 6 facing the outlet of the airflow section 7 is constructed into a tapering structure that extends obliquely towards the air outlet 13 of the casing, and a through hole is provided at the position corresponding to the air outlet 13. That is, the flow cross-section of the air guide 6 gradually decreases along the airflow direction. In addition, in order to improve the airflow flow and avoid the generation of eddies, the inner wall of the air guide 6 around the air outlet is constructed into an arc-shaped tapering structure. This tapering structure is conducive to guiding non-heat exchange air / indoor air and heat exchange air to mix fully. Furthermore, under the guidance of the tapering inner wall of the air guide 6, the airflow gradually converges towards the airflow center direction (the direction of the central axis of the air outlet 13) as it flows towards the air outlet 13, generating a converging effect, making the airflow stronger and the air delivery distance longer, ensuring that the vertical air conditioner can effectively achieve the needs of long-distance air delivery and strong air delivery.

[0062] Optionally, the air guide 6 is curved and is fastened to the air outlet of the first air duct and the air outlet of the second air duct; and a through hole is provided in the center of the curved air guide 6, which is adapted to communicate with the air outlet 13.

[0063] Optionally, the first air inlet 11 and the first fan 21 are located below the heat exchanger 3, and the second air inlet 12, the second fan 22 and the air outlet 13 are located above the heat exchanger 3.

[0064] This design makes full use of the internal structure and spatial configuration of the vertical air conditioner, ensuring that the airflow in the second and first air ducts does not interfere with each other before they are fully mixed near the air outlet 13, thus guaranteeing the flow rates of the heat exchange air and the indoor air and improving the effect of mixing and uniform airflow.

[0065] The casing 1 of the vertical air conditioner may include a front casing located at the front and a rear casing located at the back, combined with Figure 2 and Figure 3 As shown, the first air inlet 11 is located at the lower part of the rear casing. To increase the air intake, the first air inlets 11 are distributed on the back and two sides of the lower part of the vertical air conditioner, allowing indoor air to flow into the casing 1 of the vertical air conditioner from different directions through the first air inlets 11. The first fan 21 is located inside the casing 1 near the first air inlet 11, allowing the airflow flowing into the casing 1 through the first air inlet 11 to quickly enter the first air duct / heat exchange air duct. A heat exchanger 3 is installed at the outlet of the first fan 21, combined with... Figure 3 As shown, the heat exchanger 3 consists of two plate-shaped structures. These two plate-shaped structures are inclined from bottom to top and converge / join at the upper end to form a heat exchange space for airflow to exchange heat. The upward extension of the heat exchanger 3 increases the heat exchange area of ​​the airflow and improves the heat exchange effect.

[0066] Combination Figures 2 to 5 As shown, the second air inlet 12 is located on the upper part of the rear casing, away from the first air inlet 11 and the heat exchanger 3. The size of the second air inlet 12 is determined according to the required mixing ratio of non-heat exchange air. The second fan can be located above the vertical air conditioner, for example, close to the upper end plate of the casing 1. This arrangement not only keeps the first air inlet and the heat exchanger 3 away, but also minimizes the space occupied by other components inside the casing 1, which is beneficial to the internal layout of the vertical air conditioner.
