Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a device for heating the air outlet of a comfort air conditioner in a refrigerant system. Background Technology

[0002] An air conditioning outlet is a component in an air conditioning system used to deliver treated cool or hot air to the indoor space. It is the interface for heat exchange between the air conditioner and the indoor environment. The device for heating the air outlet of a refrigerant-based comfort air conditioning system is designed to increase the temperature of the air outlet. By improving the air duct design of the air conditioning outlet, the air flows more smoothly within the duct, reducing heat loss. At the same time, some devices are equipped with auxiliary fans to accelerate airflow and improve the heat exchange efficiency between the air and the heat exchanger inside the air conditioner, thereby increasing the air temperature at the outlet.

[0003] A search revealed Chinese Patent Publication No. CN110440431B, which discloses a profile and an air outlet for a central air conditioner. This profile has a slot extending along its longitudinal direction, penetrating both ends of the profile's longitudinal length, with the slot's opening facing the inner side or top of the frame. This profile can be used to form the frame of a central air conditioner's air outlet (i.e., an air outlet or return air inlet). By providing a slot on the profile, with the slot's opening facing the inner side or top of multiple frames, and the slot penetrating both ends of the profile's longitudinal length, components such as air guides, connecting columns, hinges, or clips for the central air conditioner's air outlet can be inserted into the slot from both ends of its longitudinal length, thus securing them in the slot. This simplifies assembly, makes assembly quick and easy, and improves production efficiency. However, the airflow from the air conditioner's outlet generates significant noise during operation, potentially causing discomfort to personnel exposed to the air jet for extended periods. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a device for heating the air outlet of a comfort air conditioning system using fluorine, aiming to improve the problem that the airflow from the air conditioning outlet in the prior art generates a lot of noise when blowing, which can cause discomfort to people who are in the area around the air conditioner for a long time.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for heating the air outlet of a comfort air conditioner in a refrigerant system, comprising a body, wherein multiple silencing mechanisms are equidistantly installed at the bottom of the body to reduce the noise of the air outlet; multiple covering mechanisms are equidistantly installed at the bottom of the body to cover the area; the silencing mechanism includes an elongated hollow plate, which is equidistantly installed at the bottom of the body; a support plate is fixedly connected to the bottom of the elongated hollow plate; an elongated rod is fixedly connected to an adjacent side of the outer wall of the support plate; multiple elastic ropes are fixedly connected to the outer wall of the elongated rod at equal intervals; multiple air guide plates are fixedly connected to an adjacent side of the outer wall of the support plate at equal intervals; a piston cylinder is fixedly connected to the lower middle part of the inner wall of the air guide plate; a venting groove is opened on the outer wall of the piston cylinder; a piston rod is fixedly connected to the bottom end of the elastic rope; a static pressure box is fixedly connected to the lower middle part of the outer wall of the elongated hollow plate; multiple venting grooves are equidistantly opened on the left and right sides of the outer wall of the static pressure box.

[0006] The above technical solution involves installing a long hollow plate at the bottom of the machine body, with a guide plate below it forming a flow channel. The layout of the guide plate disperses the airflow velocity and reduces noise generated by turbulence. When the airflow passes through the guide plate, the airflow impact force acts on the elastic pull rope, causing it to stretch slightly. The piston rod connected to the bottom of the elastic pull rope then reciprocates inside the piston cylinder. As the piston rod moves inside the piston cylinder, it compresses the air inside the cylinder. The compressed air is slowly discharged through the venting groove on the outer wall of the piston cylinder, reducing the noise frequency. The static pressure box connected to the long hollow plate is connected to the airflow channel through a venting groove. The internal space of the static pressure box can buffer airflow pressure fluctuations, stabilize the outlet static pressure, and reduce noise caused by sudden pressure changes, achieving a better noise reduction effect.

[0007] As a further description of the above technical solution: The covering mechanism includes a movable plate, which is equidistantly installed at the bottom of the machine body. A spring is installed on the top of the movable plate, and a covering cloth is installed on the top of the movable plate. Multiple drive mechanisms are equidistantly arranged at the bottom of the machine body.

[0008] The above technical solution allows the movable plate to unfold the covering cloth as it moves, while the spring is stretched. When the covering cloth needs to be retracted, the spring assists in rolling it up.

[0009] As a further description of the above technical solution: The driving mechanism includes a motor, which is equidistantly mounted on the bottom of the machine body. A worm gear is fixedly connected to the output end of the motor. Multiple threaded rods are equidistantly rotatably connected to the inner wall of the static pressure box. A worm wheel is fixedly connected to the bottom end of each threaded rod. Multiple hollow short blocks are equidistantly fixedly connected to the upper part of the inner wall of the static pressure box. A support short plate is installed at the bottom of the motor. A driving battery is fixedly connected to the bottom of the support short plate. Multiple sliding grooves are equidistantly opened on the inner wall of the static pressure box.

[0010] The above technical solution involves a drive battery supplying power to a motor, which in turn drives a worm gear to rotate. The worm gear meshes with a worm wheel, transmitting the rotational motion to a threaded rod. As the threaded rod rotates, a movable plate on the outer wall slides along a groove. When the motor rotates forward, the threaded rod drives the movable plate to slide outward, increasing the unfolded area of ​​the cover cloth and reducing the exposed area of ​​the ventilation slots. When the motor rotates in reverse, the movable plate slides inward, shrinking the cover cloth and increasing the opening area of ​​the ventilation slots. By controlling the unfolded area of ​​the cover cloth, the temperature of the air conditioning outlet and the comfort of the airflow can be adjusted.

[0011] As a further description of the above technical solution: The outer wall of the movable plate is slidably connected to the inside of the chute, and the bottom end of the covering cloth is fixedly connected to the top of the movable plate.

[0012] Through the above technical solution: the chute can limit the movement trajectory of the moving plate, the bottom end of the covering cloth is fixedly connected to the top of the moving plate, and the moving plate can move synchronously with the covering cloth.

[0013] As a further description of the above technical solution: The worm gear meshes with the worm wheel, and the left and right ends of the outer wall of the covering cloth are rotatably connected to the interior of the hollow short block.

[0014] The above technical solution involves the meshing of a worm gear and a worm wheel, which drives the worm wheel to rotate synchronously. The hollow short block serves to support the rotation of the covering cloth.

[0015] As a further description of the above technical solution: The top end of the spring is fixedly connected to the bottom of the hollow short block, and the bottom end of the spring is fixedly connected to the top of the moving plate.

[0016] Through the above technical solution: the hollow short block serves to support and fix the spring, and the movement of the moving plate will pull the spring to extend.

[0017] As a further description of the above technical solution: The interior of the movable plate is threadedly connected to the outer wall of the threaded rod, and the bottom of the motor is fixedly connected to the top of the supporting short plate.

[0018] The above technical solution allows the moving plate to move up and down by rotating the threaded rod, while the supporting short plate serves to fix and support the motor.

[0019] As a further description of the above technical solution: The outer wall of the machine body is fixedly connected with multiple air supply slots at equal intervals, and adjustable louvers are installed inside the air supply slots.

[0020] The above technical solution involves multiple air ducts evenly distributed on the outer wall of the unit, serving as extended channels for the air conditioner's air outlets. This guides the directional flow of treated air. When the adjustable louvers tilt upwards, the cold air rises, taking advantage of the sinking nature of cold air to avoid blowing directly on people. When heating, the louvers tilt downwards, accelerating the descent and ascent of hot air, thus improving the uniformity of indoor temperature.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the air guide plate forms a flow channel, disperses the airflow speed, reduces noise, and the airflow impacts the elastic pull rope, causing it to stretch or vibrate slightly. The piston rod then reciprocates, compresses the air and slowly discharges it, reducing the noise frequency. This avoids the problem of the airflow from the air conditioner vent generating a lot of noise when blowing, which could cause discomfort to people who are in the area around the air conditioner for a long time.

[0022] 2. In this utility model, by starting the motor worm gear to rotate and drive the threaded rod, the moving plate slides laterally, thereby unfolding or folding the cover cloth. When the cover cloth is unfolded, the ventilation groove is blocked, reducing the amount of return air drawn in by the negative pressure zone in the static pressure box. When the cover cloth is folded, the opening area of ​​the ventilation groove increases, allowing more return air to be drawn into the static pressure box and mixed with the supply air, increasing the outlet air temperature. The mixing ratio can be controlled by adjusting the opening size, and energy recovery is achieved while increasing the outlet air temperature, without the need for additional energy consumption, thus avoiding energy waste.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a device for heating the air outlet of a comfort air conditioner in a refrigerant system. The device includes a body 1, with multiple silencing mechanisms 2 equidistantly installed at the bottom of the body 1 to reduce airflow noise. Multiple covering mechanisms 3 are also equidistantly installed at the bottom of the body 1 to control the area covered. Each silencing mechanism 2 includes a long hollow plate 201 equidistantly installed at the bottom of the body 1. A support plate 205 is fixedly connected to the bottom of the long hollow plate 201. A long rod 203 is fixedly connected to one adjacent side of the outer wall of the support plate 205. Multiple elastic pull ropes 204 are fixedly connected to the outer wall of the long rod 203 at equal intervals. Multiple air guide plates 202 are fixedly connected to one adjacent side of the outer wall of the support plate 205 at equal intervals. A piston cylinder 209 is fixedly connected to the lower middle part of the inner wall of the air guide plate 202. A venting groove 210 is provided on the outer wall of the piston cylinder 209. The elastic pull ropes 204... A piston rod 208 is fixedly connected to the bottom end. A static pressure box 207 is fixedly connected to the lower middle part of the outer wall of the long hollow plate 201. Multiple ventilation slots 206 are equidistantly opened on the left and right sides of the outer wall of the static pressure box 207. The outer wall of the moving plate 301 is slidably connected to the inside of the sliding groove 3044. The bottom end of the covering cloth 302 is fixedly connected to the top of the moving plate 301. The sliding groove 3044 can limit the movement trajectory of the moving plate 301. The bottom end of the covering cloth 302 is fixedly connected to the top of the moving plate 301. The movement of the moving plate 301 can drive the covering cloth 302 to move synchronously. The worm 3048 is meshed with the worm wheel 3047. The left and right ends of the outer wall of the covering cloth 302 are rotatably connected to the inside of the hollow short block 3045. The worm 3048 is meshed with the worm wheel 3047, thereby driving the worm wheel 3047 to rotate synchronously. The hollow short block 3045 supports the covering cloth 302 to rotate. Specifically, a long hollow plate 201 is installed at the bottom of the body 1, and the air guide plate 202 below it forms a flow channel. The layout of the air guide plate 202 can disperse the airflow velocity and reduce the noise generated by turbulence. When the airflow passes through the air guide plate 202, the airflow impact force acts on the elastic pull rope 204, causing it to be slightly stretched. The piston rod 208 connected to the bottom end of the elastic pull rope 204 then reciprocates within the piston cylinder 209. When the piston rod 208 moves within the piston cylinder 209, it compresses the air inside the cylinder. The compressed air is slowly discharged through the venting groove 210 on the outer wall of the piston cylinder 209, reducing the noise frequency. The static pressure box 207 connected to the long hollow plate 201 is connected to the airflow channel through the venting groove 206. The internal space of the static pressure box 207 can buffer airflow pressure fluctuations, stabilize the outlet static pressure, and reduce noise. To reduce noise caused by sudden pressure changes and achieve a better sound insulation effect, the outer wall of the movable plate 301 is slidably connected to the inside of the slide groove 3044, and the bottom end of the covering cloth 302 is fixedly connected to the top of the movable plate 301. The slide groove 3044 can limit the movement trajectory of the movable plate 301. The bottom end of the covering cloth 302 is fixedly connected to the top of the movable plate 301. The movement of the movable plate 301 can drive the covering cloth 302 to move synchronously. The worm 3048 is meshed with the worm wheel 3047. The left and right ends of the outer wall of the covering cloth 302 are rotatably connected to the inside of the hollow short block 3045. The meshing of the worm 3048 and the worm wheel 3047 can drive the worm wheel 3047 to rotate synchronously. The hollow short block 3045 supports the rotation of the covering cloth 302.

[0027] Reference Figure 1 , Figure 6 and Figure 7 The covering mechanism 3 includes a movable plate 301, which is equidistantly installed at the bottom of the machine body 1. A spring 303 is installed on the top of the movable plate 301, and a covering cloth 302 is installed on the top of the movable plate 301. Multiple drive mechanisms 304 are equidistantly arranged at the bottom of the machine body 1. Each drive mechanism 304 includes a motor 3041, which is equidistantly installed at the bottom of the machine body 1. A worm gear 3048 is fixedly connected to the output end of the motor 3041. Multiple threaded rods 3046 are rotatably connected at equal intervals to the inner wall of the static pressure box 207. A worm wheel 3047 is fixedly connected to the bottom end of each threaded rod 3046. Multiple hollow short blocks 3045 are fixedly connected at equal intervals in the upper part of the inner wall of the static pressure box 207. A support short plate 3042 is installed at the bottom of the motor 3041. A drive battery 3043 is fixedly connected to the bottom of the support short plate 3042. Multiple sliding grooves 3044 are opened at equal intervals in the inner wall of the static pressure box 207. The top of the spring 303 is fixedly connected to the bottom of the hollow short block 3045. The bottom of the spring 303 is fixedly connected to the top of the moving plate 301. The hollow short block 3045 plays the role of supporting and fixing the spring 303. The movement of the moving plate 301 will pull the spring 303 to extend. Specifically, when the coverage area needs to be adjusted, the motor 3041 starts and drives the worm 3048 at the output end to rotate. The worm 3048 meshes with the worm wheel 3047, transmitting the rotational power to the threaded rod 3046. The worm wheel 3047 is fixed at the bottom of the threaded rod 3046, so the threaded rod 3046 rotates synchronously with the worm wheel 3047. When the threaded rod 3046 rotates, its outer thread engages with the hollow short block 3045, which is fixed to the inner wall of the static pressure chamber 207. This drives the moving plate 301 to slide laterally along the slide groove 3044. When rotating forward, the moving plate 301 unfolds outward; when rotating in reverse, it retracts inward. During the sliding process of the moving plate 301, the top-fixed covering cloth 302 is pulled synchronously. Guided by the rotation of its left and right ends within the hollow short block 3045, it unfolds or folds smoothly, preventing the cloth from getting stuck or wrinkled. A spring 303 is installed on the top of the moving plate 301. When the covering cloth 302 is retracted, its elastic tension assists in its winding and retraction, improving the smoothness of adjustment. When the covering cloth 302 unfolds, the ventilation slot 206 is partially or completely blocked, reducing the negative pressure zone in the static pressure chamber 207 and reducing the return air... As the suction volume decreases and the covering cloth 302 shrinks, the opening area of ​​the ventilation groove 206 increases, allowing more return air to be drawn into the static pressure box 207 and mixed with the supply air, thus increasing the outlet air temperature. The supply air must first pass through the static pressure box 207, utilizing the suction effect of its side openings in the negative pressure zone to achieve hot mixing of supply and return air, preventing low-temperature air from blowing directly onto the human body. The mixing ratio can be controlled by adjusting the opening size, and energy recovery is achieved while increasing the outlet air temperature. The top of the spring 303 is fixedly connected to the bottom of the hollow short block 3045, and the bottom of the spring 303 is fixedly connected to the top of the moving plate 301. The hollow short block 3045 serves to support and fix the spring 303, and the movement of the moving plate 301 will pull the spring 303 to extend.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The interior of the movable plate 301 is threadedly connected to the outer wall of the threaded rod 3046. The bottom of the motor 3041 is fixedly connected to the top of the support short plate 3042. By rotating the threaded rod 3046, the movable plate 301 can be moved up and down. The support short plate 3042 serves to fix and support the motor 3041. Multiple air supply slots 4 are fixedly connected at equal intervals on the outer wall of the body 1. Adjustable louvers 5 are installed inside the air supply slots 4. The multiple air supply slots 4 are equally distributed on the outer wall of the body 1, serving as an extension channel for the air conditioner outlet, guiding the directional flow of the treated air. When the blades of the adjustable louvers 5 are tilted upward, the cold air rises and takes advantage of the sinking characteristic of cold air to avoid blowing directly on the human body. When heating, the blades are tilted downward, accelerating the descent of hot air and the ascent of hot air, thus improving the uniformity of indoor temperature. Specifically, the interior of the movable plate 301 is threadedly connected to the outer wall of the threaded rod 3046, and the bottom of the motor 3041 is fixedly connected to the top of the support short plate 3042. By rotating the threaded rod 3046, the movable plate 301 can be driven to move up and down. The support short plate 3042 serves to fix and support the motor 3041. Multiple air supply slots 4 are fixedly connected at equal intervals on the outer wall of the body 1. Adjustable louvers 5 are installed inside the air supply slots 4.

When heating, the blades are tilted downward, accelerating the descent and ascent of hot air, thus improving the uniformity of indoor temperature.

[0029] Working principle: The elongated hollow plate 201 is installed at the bottom of the body 1. The air guide plate 202 below it forms a flow channel. The layout of the air guide plate 202 can disperse the airflow speed and reduce the noise generated by turbulence. When the airflow passes through the air guide plate 202, the airflow impact force acts on the elastic pull rope 204, causing it to be slightly stretched. The piston rod 208 connected to the bottom end of the elastic pull rope 204 then reciprocates in the piston cylinder 209. When the piston rod 208 moves in the piston cylinder 209, it will compress the air in the cylinder. The compressed air is slowly discharged through the vent groove 210 on the outer wall of the piston cylinder 209, reducing the noise frequency. The static pressure box 207 connected to the elongated hollow plate 201 is connected to the airflow channel through the vent groove 206. The internal space of the static pressure box 207 can buffer the airflow pressure fluctuation, stabilize the outlet static pressure, and reduce the noise caused by sudden pressure changes, achieving a better sound insulation effect. This avoids the problem of the airflow from the air conditioner outlet generating a lot of noise when blowing, which may cause discomfort to people who are in the area around the air conditioner for a long time. When the coverage area needs to be adjusted, the motor 3041 starts and drives the worm 3048 at the output end to rotate. The worm 3048 meshes with the worm wheel 3047, transmitting the rotational power to the threaded rod 3046. The worm wheel 3047 is fixed at the bottom of the threaded rod 3046, so the threaded rod 3046 rotates synchronously with the worm wheel 3047. When the threaded rod 3046 rotates, its outer thread engages with the hollow short block 3045, which is fixed to the inner wall of the static pressure box 207. This drives the moving plate 301 to slide laterally along the slide groove 3044. When rotating forward, the moving plate 301 unfolds outward; when rotating in reverse, it retracts inward. During the sliding process of the moving plate 301, the top-fixed covering cloth 302 is pulled synchronously. Guided by the rotation of its left and right ends within the hollow short block 3045, it unfolds or folds smoothly, preventing the cloth from getting stuck or wrinkled. A spring 303 is installed on the top of the moving plate 301. When the covering cloth 302 is retracted, the elastic tension assists in its winding and retraction, improving smooth adjustment. When the covering cloth 302 is open, the ventilation slots 206 are partially or completely blocked, reducing the amount of return air drawn in by the negative pressure zone in the static pressure box 207. When the covering cloth 302 is closed, the opening area of ​​the ventilation slots 206 increases, and more return air is drawn into the static pressure box 207 to mix with the supply air, increasing the outlet air temperature. The supply air must first pass through the static pressure box 207, utilizing the suction effect of its side openings in the negative pressure zone to achieve hot mixing of supply and return air, avoiding low-temperature air blowing directly onto the human body. The mixing ratio can be controlled by adjusting the size of the openings, and energy recovery is achieved while increasing the outlet air temperature, without additional energy consumption, thus avoiding energy waste.
