[0038] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0039] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0040] Example 1

[0041] like Figures 1 to 9 As shown, in this embodiment, the air conditioner air outlet adopts a mounting plate 1 arranged symmetrically on the left and right. Between the two mounting plates 1, an upper adjustment component and a lower adjustment component are rotatably connected respectively. Each adjustment component includes a main adjustment plate 2 rotatably connected to the mounting plate 1. One end of the main adjustment plate 2 is rotatably connected to a secondary adjustment plate 3, and the top end of the main adjustment plate 2 is fixedly connected to a return flow plate 4.

[0042] The main regulating plate 2 has an arc-shaped structure along the cross-section perpendicular to the line connecting the two mounting plates 1, and the protruding direction of its arc-shaped structure faces the return plate 4.

[0043] The return plate 4 is also an arc-shaped structure, with the same curvature as the auxiliary regulating plate 3, ensuring the streamline and smoothness of the overall structure of the air outlet.

[0044] The end of the main regulating plate 2 away from the secondary regulating plate 3 adopts a cylindrical structure, which is tangent to the arc-shaped structure of the main regulating plate 2; at the same time, the end of the return plate 4 away from the secondary regulating plate 3 bends toward the two main regulating plates 2, and the bent part extends between the two main regulating plates 2, further optimizing the structure of the return and mixing chamber.

[0045] Multiple front adjustment pipes 6, middle adjustment pipes 7 and rear adjustment pipes 8 are fixedly connected to the main adjustment plate 2. These pipes are evenly distributed along the line connecting the two mounting plates 1. The front adjustment pipes 6 are all located on the side closer to the secondary adjustment plate 3, while the rear adjustment pipes 8 are located on the side farther away from the secondary adjustment plate 3, and the middle adjustment pipes 7 are located between the two.

[0046] All the adjusting tubes (front adjusting tube 6, middle adjusting tube 7, rear adjusting tube 8) are hollow structures, penetrating the main adjusting plate 2 and the return plate 4, the top end of the hollow part is communicated with the space on the upper side of the return plate 4, and the bottom end is communicated with the space on the lower side of the main adjusting plate 2, so as to realize the premixing effect.

[0047] A plurality of heat conducting pipes 9 are fixedly connected in the main adjusting plate 2, the heat conducting pipes 9 are uniformly distributed along the connecting line between the two mounting plates 1, and each heat conducting pipe 9 is located between two adjacent rear adjusting tubes 8, so that the uniform heat conduction is effectively realized, and the local temperature difference is reduced.

[0048] A plurality of impellers 5 are arranged at the positions where the main adjusting plate 2 and the auxiliary adjusting plate 3 are rotationally connected, the impellers 5 protrude 1-3 mm from the bottom end of the main adjusting plate 2 at the positions close to the two main adjusting plates 2.

[0049] In order to ensure the movement of the impellers 5 and the cooperation with the external airflow, the main adjusting plate 2 and the auxiliary adjusting plate 3 are provided with grooves matched with the outer ends of the impellers 5 at the positions corresponding to the impellers 5, and the return plate 4 is provided with air inlets at the positions corresponding to the impellers 5, so as to realize the guidance and distribution of the airflow.

[0050] The two auxiliary adjusting plates 3 arranged symmetrically upwards and downwards are fixedly connected with adjusting sheets 10 at the positions corresponding to the front adjusting tubes 6, the middle adjusting tubes 7 and the rear adjusting tubes 8 at one end close to each other, the adjusting sheets 10 are made of bimetallic material, although the structure is mainly reserved in the embodiment, but it provides a technical basis for the subsequent temperature response adjustment.

[0051] The main adjusting plate 2 is fixedly connected with an adjusting gear 11 at the position rotationally connected with the mounting plate 1, the outer end of the adjusting gear 11 is engaged with a driving gear 12, the driving gear 12 is connected with the adjusting gear 11 through an external driving system, so as to realize the linkage rotation of the main adjusting plate 2, the auxiliary adjusting plate 3 and the return plate 4, thereby accurately adjusting the air outlet.

[0052] In the actual use process, the working process of the air conditioner air outlet is as follows:

[0053] Air outlet adjustment

[0054] The external driving system applies a rotating force to the adjusting gear 11 through the driving gear 12, so that the main adjusting plate 2 rotates in linkage.

[0055] When it is needed to increase the area of the air outlet, the two main adjusting plates 2 rotate to one side of the auxiliary adjusting plate 3 respectively, so that the air outlet is increased; on the contrary, when it is needed to reduce the area of the air outlet to increase the airflow speed, the two main adjusting plates 2 rotate to the auxiliary adjusting plate 3, thereby reducing the air outlet.

[0056] Airflow acceleration and premixing preheating

[0057] Due to the tapered air inlet structure formed between the main adjustment plate 2 and the secondary adjustment plate 3, the reduced air supply port cross-sectional area can significantly increase the local airflow speed according to the Venturi effect, forming a low-pressure area near the secondary adjustment plate 3.

[0058] The cold air enters the mixed air chamber through the gap of about 4-5 mm between the main adjustment plate 2 and the return plate 4. In the mixed air chamber, the front adjustment pipe 6, the middle adjustment pipe 7, and the rear adjustment pipe 8 pre-mix the airflow, fully mixing the originally low-temperature air conditioning cold air with the indoor return air, appropriately increasing the supply air temperature, and effectively reducing the dewing phenomenon.

[0059] Uniform heat distribution and external gas introduction

[0060] The multiple heat-conducting pipes 9 are uniformly distributed in the main adjustment plate 2, rapidly conducting heat to each part, reducing local temperature difference, and reducing dewing caused by excessive temperature difference.

[0061] At the same time, the impeller 5 is driven to rotate when the airflow passes through, which further promotes the introduction of external gas into the mixed air chamber through the air inlet on the return plate 4, pre-mixing with the cold air, and making the entire supply air system temperature more balanced.

[0062] Through the control of the external driving system on the drive gear 12, the adjustment gear 11 drives the main adjustment plate 2 and the secondary adjustment plate 3 to rotate together, realizing flexible adjustment of the air supply port area, quickly switching between increasing the air supply coverage area and improving the airflow speed according to the needs, meeting the requirements of preventing dewing under different working conditions.

[0063] Stable airflow guidance and pre-mixing effect, the main adjustment plate 2 and the return plate 4 are both arc-shaped structures, and are finely designed in structure to ensure that the airflow flows stably and smoothly in the air supply port area, forming a low-pressure area locally through the Venturi effect, fully mixing the cold air with the return air in the mixed air chamber, achieving the purpose of preheating the air conditioning cold air, and effectively preventing dewing.

[0064] Uniform heat distribution and local temperature difference reduction, the heat-conducting pipes 9 are uniformly arranged in the main adjustment plate 2, rapidly transferring heat to each part, reducing local temperature difference, and reducing the risk of dewing caused by excessively low local temperature.

[0065] Reserved advantages of auxiliary adjustment structure, although the adjustment sheet 10 mainly serves as a structural reservation in this embodiment, its bimetallic property provides potential technical support for temperature response adjustment, further enhancing the anti-dewing function, and ensuring the system still has high reliability and safety in low-temperature environments.

[0066] Through the above structural configuration and working process, this embodiment can play a significant role in adjusting the air outlet area, accelerating the airflow velocity, achieving full premixing of cold air and return air, and balancing heat transfer, ultimately achieving the purpose of effectively preventing condensation, increasing the air supply temperature of the air conditioner, and improving the quality of the air supply.

[0067] Example 2

[0068] like Figures 1 to 9 As shown, this embodiment adds a temperature response adjustment function to the basic structure of embodiment 1. All structural components are fixedly connected and configured according to numerical identifiers. Its structure includes:

[0069] Basic structural parts

[0070] Mounting plate 1 is symmetrically arranged on the left and right sides, providing support and a fixed base for the entire air conditioning vent.

[0071] The main adjustment plate 2 is rotatably connected to the mounting plate 1 to form an adjustment mechanism. Its cross-section is an arc-shaped structure (the protruding direction faces the return plate 4), and one end is provided with a cylindrical structure. This structure is tangent to the arc-shaped structure of the main adjustment plate 2 to ensure the smoothness of the overall structure.

[0072] One end of the auxiliary regulating plate 3 is rotatably connected to the main regulating plate 2, and together with the regulating plate 10, they form a temperature response area through a fixed connection.

[0073] The return plate 4 is fixedly connected to the top of the main regulating plate 2. It is also an arc-shaped structure with the same curvature as the auxiliary regulating plate 3. It is used to guide outside air into the mixing chamber.

[0074] The impeller 5 is installed at the rotatable connection between the main regulating plate 2 and the auxiliary regulating plate 3. Its outer end protrudes 1-3 mm from the bottom of the main regulating plate 2 near the position between the two main regulating plates 2, and cooperates with the air inlet on the return plate 4 to achieve enhanced airflow efficiency.

[0075] The front regulating pipe 6, the middle regulating pipe 7, and the rear regulating pipe 8 are fixedly connected to the main regulating plate 2 and are evenly distributed along the line connecting the two mounting plates 1. The front regulating pipe 6 is closer to the side of the secondary regulating plate 3, the rear regulating pipe 8 is located away from the secondary regulating plate 3, and the middle regulating pipe 7 is located between the two. These pipes are all hollow structures that pass through the main regulating plate 2 and the return plate 4. The top of their interiors is connected to the upper space of the return plate 4, and the bottom is connected to the lower space of the main regulating plate 2, which facilitates the premixing of air.

[0076] The heat pipes 9 are all arranged inside the main regulating plate 2 and are evenly distributed between the two mounting plates 1. Each heat pipe 9 is located between two adjacent rear regulating pipes 8 to evenly transfer the heat on the main regulating plate 2 and reduce the local temperature difference.

[0077] Temperature response regulation section

[0078] The adjusting piece 10 is the core temperature response component of the present embodiment, and is made of bimetallic material. The adjusting piece 10 is arranged in the region corresponding to the front adjusting pipe 6, the middle adjusting pipe 7 and the rear adjusting pipe 8 in structure, and is connected to the main adjusting plate 2 by a fixed manner at the end away from the auxiliary adjusting plate 3. When the air temperature is lower than the preset threshold (which is higher than the dew point), the end of the adjusting piece 10 close to the auxiliary adjusting plate 3 will bend away from the main adjusting plate 2 due to the bimetallic effect, thereby driving the corresponding adjusting pipe (the front adjusting pipe 6, the middle adjusting pipe 7 or the rear adjusting pipe 8) to open.

[0079] Transmission mechanism

[0080] The adjusting gear 11 is fixedly connected at the rotating connection between the main adjusting plate 2 and the mounting plate 1.

[0081] The driving gear 12 is engaged with the adjusting gear 11 and is driven by an external driving system. The driving gear 12 drives the main adjusting plate 2, the auxiliary adjusting plate 3 and the return plate 4 to rotate as a whole, thereby adjusting the area of the air outlet.

[0082] In use, the driving gear 12 is driven to rotate by the external driving system as needed. The driving gear 12 drives the adjusting gear 11 to rotate in the process of rotating, and the adjusting gear 11 further drives the main adjusting plate 2, the auxiliary adjusting plate 3 and the return plate 4 to rotate together. When it is needed to increase the area of the air outlet, the two main adjusting plates 2 are driven to rotate away from each other at the end close to the auxiliary adjusting plate 3. When it is needed to reduce the area of the air outlet to increase the air flow rate, the two main adjusting plates 2 are driven to move closer to each other at the end close to the auxiliary adjusting plate 3. Since the air pressure blown out from the air conditioner is relatively constant, the air flow rate and pressure flowing between the two auxiliary adjusting plates 3 will change after the area of the air outlet is adjusted. In practice, the two auxiliary adjusting plates 3 are rotated so that the distance between the ends of the two auxiliary adjusting plates 3 away from the main adjusting plate 2 is greater than the distance between the ends of the two auxiliary adjusting plates 3 close to the main adjusting plate 2. At this time, the Venturi nozzle structure is formed between the upper adjusting assembly and the lower adjusting assembly arranged symmetrically above and below. The air flow rate at the position between the two main adjusting plates 2 close to the auxiliary adjusting plate 3 is accelerated, and the pressure in this region is reduced. The accelerated air flow rate helps to reduce the condensation.

[0083] When the temperature of the air flow between the two main adjusting plates 2 reaches the preset threshold, the adjusting sheet 10 at the corresponding position starts to deform, thereby causing the corresponding front adjusting pipe 6, middle adjusting pipe 7 or rear adjusting pipe 8 to be opened, at this time, the front adjusting pipe 6 is arranged close to the auxiliary adjusting plate 3, and the position is low in air pressure under the action of the air flow, thereby causing the air flow at the top end of the front adjusting pipe 6 to flow to the space between the two main adjusting plates 2 under the action of the air pressure difference, and after the adjusting sheet 10 close to the auxiliary adjusting plate 3 moves away from the main adjusting plate 2, the air pressure difference is caused between the side close to the main adjusting plate 2 and the side away from the main adjusting plate 2 of the adjusting sheet 10, thereby causing the middle adjusting pipe 7 and the air at the top end to flow to the side close to the adjusting sheet 10, and since the front adjusting pipe 6, the middle adjusting pipe 7 and the rear adjusting pipe 8 are communicated with the space needing to be adjusted in temperature, the air entering the front adjusting pipe 6, the middle adjusting pipe 7 and the rear adjusting pipe 8 is premixed with the air of the air conditioner, thereby causing the temperature of the air flowing between the two auxiliary adjusting plates 3 to be appropriately increased, so that the dew condensation is reduced.

[0084] In use, the plurality of heat-conducting pipes 9 uniformly distribute the heat on the main adjusting plate 2, thereby reducing the temperature difference of each part of the main adjusting plate 2 and reducing the possibility of dew condensation on the main adjusting plate 2.

[0085] When the air flow flows between the two auxiliary adjusting plates 3, the air flow drives the plurality of impellers 5 to rotate, the impellers 5 drive the external air to flow in the process of rotating, so that the external air enters the space away from the auxiliary adjusting plate 3 between the two main adjusting plates 2 through the gap between the main adjusting plate 2 and the return plate 4, and the entering external air is premixed with the air of the air conditioner, thereby increasing the temperature of the air and reducing the possibility of dew condensation.

[0086] When the distance between the two main adjusting plates 2 close to the auxiliary adjusting plate 3 is reduced, the air flow speed between the two main adjusting plates 2 close to the auxiliary adjusting plate 3 is increased, thereby increasing the rotating speed of the impeller 5.

[0087] Rotating the main adjusting plate 2 and the auxiliary adjusting plate 3 can adjust the air flow direction, each main adjusting plate 2 and auxiliary adjusting plate 3 can be independently adjusted, the main adjusting plate 2 can be adjusted by using a driving system to adjust the angle or manually rotating the main adjusting plate 2, and the auxiliary adjusting plate 3 is adjusted by manual adjustment.

[0088] The utility model discloses through, adjustable main adjusting plate 2 and auxiliary adjusting plate 3, through adjusting main adjusting plate 2 and auxiliary adjusting plate 3 angle, adjust the air supply coverage area, avoid cold air concentration and lead to local low temperature.

[0089] The main adjusting plate 2 and the auxiliary adjusting plate 3 form a tapered air outlet structure, the air outlet cross-sectional area is reduced, the wind speed is increased, such as the Venturi effect, and the contact time of the cold air with the air outlet surface is reduced.

[0090] The return air plate 4, the impeller 5, the front regulating pipe 6, the middle regulating pipe 7 and the rear regulating pipe 8 are mixed by introducing return air, and a mixed air chamber is formed between the two main regulating plates 2. The mixed air chamber is arranged in front of the air supply port, and part of the indoor return air is mixed with the cold air to appropriately increase the air supply temperature and reduce the temperature difference.

[0091] A variable cross-section air port is formed between the two main regulating plates 2 and the two auxiliary regulating plates 3. The opening and closing degree of the air port is adjusted by an external driving system or manually, so as to control the air volume and air speed and avoid cold accumulation at a low speed.

[0092] Working process

[0093] Basic regulating process

[0094] In use, the external driving system first applies a rotating force to the regulating gear 11 through the driving gear 12, and then synchronously rotates the main regulating plate 2, the auxiliary regulating plate 3 and the return air plate 4.

[0095] When it is necessary to increase the air supply coverage area, the two main regulating plates 2 are respectively rotated to one side of the auxiliary regulating plate 3; conversely, in order to increase the air flow speed, the two main regulating plates 2 are rotated to approach the auxiliary regulating plate 3, so as to adjust the air outlet area.

[0096] In this process, a tapered air port (Venturi nozzle structure) is formed between the upper and lower symmetrical regulating assemblies, so that the local air flow speed near the main regulating plate 2 is accelerated, and the local air pressure is reduced, which is helpful to prevent dewing.

[0097] Temperature response automatic regulating process

[0098] When the air temperature flowing through the air supply port is reduced and reaches a preset threshold value (the threshold value is higher than the dew point), the regulating sheet 10 at the corresponding position senses the temperature change. Due to the bimetallic characteristic, one end of the regulating sheet 10 near the auxiliary regulating plate 3 is bent and moves away from the main regulating plate 2.

[0099] The deformation of the regulating sheet 10 causes the front regulating pipe 6, the middle regulating pipe 7 or the rear regulating pipe 8 to be opened. Specifically:

[0100] The front regulating pipe 6 is located near the auxiliary regulating plate 3, and under the action of the lower local air pressure, the gas at the top end of the front regulating pipe 6 flows to the space between the two main regulating plates 2 under the action of the air pressure difference.

[0101] At the same time, the middle regulating pipe 7 and the rear regulating pipe 8 are opened under the driving of the regulating sheet 10, forming an additional gas inlet channel.

[0102] The gas entering through the regulating pipes 6, 7 and 8 is premixed with the air conditioning cold air, so that the gas temperature in the mixed air chamber is increased, thereby effectively reducing the dewing phenomenon caused by excessive temperature difference.

[0103] Auxiliary air mixing and heat balance

[0104] In the adjustment process, the heat pipes 9 arranged uniformly in the main adjustment plate 2 uniformly distribute heat to each part, reduce the local temperature difference, and further prevent the risk of condensation caused by too low local temperature.

[0105] At the same time, when the air flow passes through the two auxiliary adjustment plates 3, it drives the impeller 5 to rotate, accelerates the outside air to enter the air mixing chamber through the gap between the main adjustment plate 2 and the return plate 4, and the outside air and the air conditioning cold air are fully premixed in the air mixing chamber, which improves the supply air temperature as a whole.

[0106] When the distance between the two main adjustment plates 2 near the auxiliary adjustment plate 3 decreases, the air flow speed in this area further increases, which promotes the increase of the rotating speed of the impeller 5, and enhances the introduction effect of the outside air.

[0107] Temperature self-adaptive adjustment, using bimetallic adjustment sheet 10, when the air temperature is lower than the preset threshold, automatic bending occurs, so that the front adjustment pipe 6, the middle adjustment pipe 7 or the rear adjustment pipe 8 is opened, so that the premixed gas enters the air mixing chamber, rapidly improves the supply air temperature, and effectively prevents the occurrence of condensation.

[0108] Precise air flow control and air mixing effect, through the external driving system to drive the drive gear 12, the adjustment gear 11, the main adjustment plate 2, the auxiliary adjustment plate 3 and the return plate 4 are linked and rotated to realize flexible adjustment of the supply air outlet area. The Venturi nozzle structure formed in the adjustment process can accelerate the air flow, reduce the local air pressure, further optimize the premixing effect, ensure that the cold air and return air are fully mixed, so as to reduce the risk of condensation.

[0109] Heat balance distribution and rapid response, the heat pipes 9 arranged uniformly in the main adjustment plate 2 can quickly and uniformly distribute heat to each part, reduce the local temperature difference, and ensure that the adjustment sheet 10 and the adjustment pipes 6, 7, 8 respond quickly. The intelligent response of the bimetallic adjustment sheet 10 enables the system to quickly adjust when the ambient temperature changes, ensuring that the supply air temperature is always in the ideal range of preventing condensation.
