Description

Technical Field

[0001] This utility model belongs to the field of air conditioning air supply technology, and in particular relates to a refrigeration air conditioning air supply device. Background Technology

[0002] An air conditioner is a device that artificially regulates the air in a specific space to meet human comfort and production needs. Most existing air conditioners use a cross-flow fan to continuously bring air into the fins of the evaporator for heat exchange, and then send the cooled air into the room, thus achieving the function of delivering cool air.

[0003] Chinese patent CN219160577U discloses an air supply structure for an air conditioner. The paper states that it "includes an air conditioning unit, an installation component, and an air supply component. The air conditioning unit specifically consists of a compressor, a blower, and a return air fan. The installation component is installed on one side of the air conditioning unit, and the air supply component is installed on the same side as the installation component." This invention, by incorporating an air supply component, utilizes a protective cover to enclose the air outlet duct, a filter plate to filter the air, ensuring clean indoor air, a micro motor to drive a drive shaft to rotate, which in turn drives a guide plate to rotate, thereby controlling the airflow direction, a guide fan to direct hot and cold air within the air supply duct to prevent uneven airflow, a one-way valve to prevent backflow, and elastic clips to facilitate the disassembly and cleaning of the guide plate, achieving excellent air supply performance.

[0004] However, the above process is cumbersome and inconvenient to disassemble and assemble the filter. After long-term use, the filter will become clogged and needs to be disassembled in time. At the same time, in the above solution, the guide fan is located above the air supply duct, which will draw in fresh air from outside when it is working. This will also draw in external dust and heat, further increasing the filtration burden on the filter plate and reducing the cooling effect. Therefore, it is necessary to design a cooling air conditioning air supply device. Utility Model Content

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Example 1

[0027] A preferred embodiment of the refrigeration and air conditioning air supply device provided by this utility model is, for example... Figures 1 to 5 As shown: A refrigeration and air conditioning air supply device includes an air supply duct 1; a filter assembly 2 installed on one side of the air supply duct 1, the filter assembly 2 being used to discharge pure gas from the exhaust duct 3; an exhaust duct 3 fixedly connected to one side of the bottom end of the air supply duct 1, the top end of the exhaust duct 3 communicating with the bottom end of the air supply duct 1, an axial flow fan 4 fixedly connected to the upper end of the inner wall of the exhaust duct 3, and a grille 5 engaged at the bottom end of the exhaust duct 3; and an air regulating assembly 6 installed at the lower end of the exhaust duct 3, the air regulating assembly 6 being used to adjust the airflow direction.

[0028] It should be noted that some existing air conditioning air supply devices still have certain shortcomings in actual use. After long-term use, the filter screen will become clogged and needs to be disassembled in time. At the same time, in the above solution, the deflector fan is located above the air supply duct, which will draw in fresh air from outside when it is working. This will also draw in external dust and heat, further increasing the filtration burden on the filter screen and reducing the cooling effect.

[0029] In this embodiment, one end of the air supply duct 1 is connected to the air outlet of the refrigeration air conditioner. After the air conditioner's cold air is filtered again by the filter component 2, the cold air can be blown out from the bottom of the exhaust duct 3 by the axial flow fan 4 to realize the air supply operation of the refrigeration air conditioner. In addition, the air adjustment component 6 is set to change the air outlet direction to meet the air supply needs under different conditions. Furthermore, the grille 5 is set to prevent large impurities from entering the interior of the exhaust duct 3.

[0030] In a further preferred embodiment of the present utility model, the filter assembly 2 comprises: a fixing groove (206) provided on one side of the bottom end of an air supply duct 1, and a sealing plate (202) arranged on one side of the bottom end of the air supply duct 1; a dust collection box 201 fixedly connected to the top end of the sealing plate 202, wherein the top end of the dust collection box 201 is fixedly connected with a filter plate 203 extending into the air supply duct 1; and a mounting structure 204 assembled on one side of the bottom end of the air supply duct 1, wherein the mounting structure 204 is configured to realize quick disassembly and assembly of the sealing plate 202 and the bottom end of the air supply duct 1.

[0031] In a further preferred embodiment of the present utility model, a sealing strip 205 is fixedly connected to the upper end of the surface of the sealing plate 202, and the sealing strip 205 is in a shape of a square ring.

[0032] In a further preferred embodiment of the present utility model, the sealing plate 202 is convex, and the cross-sectional area of the bottom end of the sealing plate 202 is larger than that of the opening of the fixing groove 206.

[0033] In this embodiment, cold air is filtered by the filter plate 203, so as to prevent impurities such as dust from being blown out from the bottom end of an exhaust duct 3 together, which causes discomfort to indoor users, and impurities such as dust filtered out by the filter plate 203 will fall into the dust collection box 201 for storage after sedimentation, reducing the number of times of disassembling and cleaning the filter plate 203. Besides, by using the sealing plate 202 with a larger area and the square-ring-shaped sealing strip 205, the sealing performance between the sealing plate 202 and the inside of the fixing groove 206 is improved, so as to prevent cold air from accidentally leaking from the gap.

[0034] In a further preferred embodiment of the present utility model, the mounting structure 204 comprises: mounting grooves 2047 provided at equal intervals on the bottom end of the air supply duct 1, wherein a sliding rod 2045 is fixedly connected to the inner wall of the mounting groove 2047, a sliding block 2044 is slidably connected to the surface of the sliding rod 2045, and a mounting block 2042 is fixedly connected to the lower end of one side of the sliding block 2044; a mounting spring 2046 wound on the surface of the sliding rod 2045, wherein two ends of the mounting spring 2046 are respectively fixedly connected with one side of the sliding block 2044 and the inner wall of the mounting groove 2047; and mounting holes 2041 provided at equal intervals on one side of the sealing plate 202.

[0035] In a further preferred embodiment of the present utility model, one end of the mounting block 2042 and the inside of the mounting hole 2041 form a clamping structure, and there are three mounting holes 2041 and three mounting blocks 2042 arranged at equal intervals respectively.

[0036] In a further preferred embodiment of the present utility model, a pulling frame 2043 is fixedly connected to one side of the sliding block 2044, and the pulling frame 2043 is mountain-shaped.

[0037] In this embodiment, by actuating the pull bracket 2043, the sliding block 2044 slides on the surface of the slide rod 2045 to compress the mounting spring 2046, thereby causing the mounting block 2042 to slide completely away from the inside of the mounting hole 2041, thus realizing the disassembly and opening of the sealing plate 202 from the inside of the fixing groove 206. During installation, the elastic force of the mounting spring 2046 can be used to make the sliding block 2044 slide and drive the mounting block 2042 to slide and lock into the inside of the mounting hole 2041, ensuring the firm and stable engagement of the sealing plate 202 and the fixing groove 206, thereby realizing the quick disassembly and assembly between the sealing plate 202 and the bottom end of the air supply duct 1.

[0038] Example 2

[0039] Based on Embodiment 1, a preferred embodiment of the refrigeration and air conditioning air supply device provided by this utility model is as follows: Figures 1 to 5 As shown: The air conditioning component 6 includes: a reserved groove 602 opened at the lower end of one side inside the exhaust pipe 3, with gears 606 rotatably connected at equal intervals to the inner wall of the reserved groove 602; a pneumatic telescopic rod 607 fixedly connected to the lower end of one side of the back of the exhaust pipe 3, the output end of the pneumatic telescopic rod 607 extending into the interior of the reserved groove 602 and fixedly connected to a toothed plate 604, the toothed plate 604 meshing with the surface of the gears 606; and a guide plate 601 rotatably connected at equal intervals to the lower end of the inner wall of the exhaust pipe 3, one end of the guide plate 601 being fixedly connected to one end of the gears 606.

[0040] In a further preferred embodiment of the present invention, a sliding groove 603 is provided at the lower end of the inner wall of the reserved groove 602, and a sliding plate 605 that slides and engages with the inside of the sliding groove 603 is fixedly connected to both sides of the toothed plate 604.

[0041] In this embodiment, the pneumatic telescopic rod 607 is activated to drive the toothed plate 604 to slide, and the sliding plate 605 slides inside the slide groove 603, so that the toothed plate 604 slides smoothly. The meshing between the toothed plate 604 and the gear 606 causes the gear 606 to rotate, which in turn drives the guide plate 601 to rotate. This allows the tilt angle of multiple guide plates 601 to be changed, so that the air outlet direction can be changed to meet the air supply needs under different conditions.

[0042] In summary, the filter assembly 2 filters the supplied cold air, preventing dust and other impurities from being discharged through the exhaust duct 3. At the same time, the dust collection box 201 can collect the filtered dust and other impurities, reducing the number of times the filter plate 203 needs to be disassembled and reassembled. Furthermore, the installation structure 204 allows for quick disassembly and cleaning of the sealing plate 202 and the filter plate 203, and the air adjustment assembly 6 can adjust the direction of air supply.
