Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to an outdoor air conditioning unit with secondary filtration capability. Background Technology

[0002] An outdoor unit of an air conditioner is part of a central air conditioning or split air conditioning system. Its main function is to expel heat from the indoor unit to the outdoor unit, thereby reducing the indoor temperature.

[0003] During operation, a large amount of air flows inside the existing outdoor unit of an air conditioner, which can easily lead to the accumulation of dust inside.

[0004] To overcome the above-mentioned defects, a prior art Chinese patent (publication number: CN219199424U) discloses an air intake volume adjustment mechanism for an air conditioning unit, including a housing, a housing cover, and an air inlet located at the bottom of one side of the housing; a filter plate is fixedly connected between the front and back sides of the housing cavity; a deflector plate can be moved up and down by a lead screw, a vertical rod, and a movable plate, thereby adjusting its position. Since there are multiple air inlets, the position of the deflector plate can be adjusted to block a certain number of air inlets, thereby reducing the amount of air entering the air inlet and thus reducing the air intake volume. Since the air inlet frequently brings in outside air, the filter plate filters dust and impurities in the air entering the air inlet. Over time, a large amount of dust and impurities will accumulate on the surface of the filter plate. Because a cleaning brush is installed on the side of the deflector plate near the filter plate, the lead screw can not only adjust the air intake volume but also clean the impurities on the surface of the filter plate.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation: when the filter screen filters the air drawn into the outdoor unit of the air conditioner, dust will adhere to the filter screen, and existing filter screens are generally located inside the casing, making it inconvenient to disassemble and clean the filter screen. Utility Model Content

[0006] The purpose of this utility model is to provide an outdoor air conditioning unit with secondary filtration capability, so as to solve the problem in the above-mentioned background technology that when the filter screen filters the air drawn into the outdoor unit of the air conditioner, dust will adhere to the filter screen, and the existing filter screen is generally located inside the casing, which makes it inconvenient to disassemble and clean the filter screen.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an outdoor air conditioning unit with secondary filtration capability, comprising an outer casing, wherein a bottom plate and a top plate are respectively fixedly connected to the top and bottom of the outer casing by bolts, and the bottom plate is connected to the mounting bracket.

[0008] The top plate has a dustproof structure inside, and two mounting holes are fixedly connected to the top of the top plate. The dustproof structure includes a mounting frame that is slidably connected to the inside of the mounting holes, and a filter screen is fixedly connected inside the mounting frame. There are two mounting frames and two filter screens, and the mounting frames and filter screens are distributed in an L-shaped structure inside the outer shell.

[0009] The front of the outer casing is equipped with a direct-blowing structure to deflect the wind direction.

[0010] Preferably, an adsorption strip is fixedly connected to the top of the mounting frame, and a handle is fixedly connected to the top of the adsorption strip. Both the adsorption strip and the handle are designed as L-shaped structures. The bottom of the adsorption strip and the top of the top plate are in contact with each other, and a magnet is provided at the bottom of the adsorption strip. The adsorption strip is adsorbed onto the top of the top plate by the magnet.

[0011] Preferably, the housing has two independent spaces inside, and an electronic control component and a compressor component are fixedly connected inside the right side of the housing, and the electronic control component and the compressor component are separated from each other by a partition.

[0012] Preferably, fins are fixedly connected to the inside of the left side of the outer shell, and the fins are distributed in an L-shaped structure on the rear side of the inner side of the outer shell, and the fins are composed of metal sheets that are equidistantly distributed along the inner side of the outer shell.

[0013] Preferably, each end of the fin is provided with a mounting rail, and each mounting rail consists of two symmetrically distributed guide rails, and the inner side of each mounting rail is slidably connected to the mounting frame.

[0014] Preferably, the rear and left sides of the outer shell are provided with ventilation openings, and the ventilation openings are aligned with the fins. The outer shell is provided with a bracket, and the upper and lower ends of the bracket are fixedly connected to the bottom plate and the top plate, respectively. A motor is fixedly connected in the middle of the bracket, and a fan is fixedly connected to the output end of the motor.

[0015] Preferably, a metal pipe is fixedly connected inside the fin, and the metal pipe is distributed in an S-shape inside the fin. Both ends of the metal pipe are connected to the compressor assembly, and the fin is located between two mounting frames.

[0016] Preferably, the anti-direct-blow structure includes a guide groove fixedly connected to the front side of the outer shell, and the outer shell has an opening, and a protective net is fixedly connected inside the opening. The guide groove has guide strips that are evenly distributed inside, and the ends of the guide strips in the guide groove all extend upwards, and the protective net is located inside the guide groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This type of outdoor air conditioning unit with secondary filtration can separate the handle and the adsorption strip by pulling the handle at the top of the adsorption strip. Then, the adsorption strip drives the mounting frame to slide upward in the mounting hole, so that the mounting frame with the filter screen moves upward. This separates the dustproof structure formed by the mounting frame, filter screen, adsorption strip and handle from the outer shell and top plate, thus facilitating the cleaning and replacement of the filter screen.

[0019] Furthermore, since the guide strips of the guide groove extend upwards, when air comes into contact with the guide groove and guide strip, the guide groove and guide strip will guide the air, causing the air to flow upwards, thus preventing the air discharged from the outdoor unit of the air conditioner when it is installed at a low position from blowing directly onto people and objects.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides the following technical solution:

[0029] An outdoor air conditioning unit with secondary filtration includes an outer casing 1. The top and bottom of the outer casing 1 are respectively fixedly connected to a bottom plate 2 and a top plate 3 by bolts, and the bottom plate 2 is connected to a mounting bracket.

[0030] The top plate 3 has a dustproof structure inside, and two mounting holes 4 are fixedly connected to the top of the top plate 3. The dustproof structure includes a mounting frame 5 that is slidably connected to the inside of the mounting holes 4, and a filter screen 6 is fixedly connected inside the mounting frame 5. There are two mounting frames 5 and two filter screens 6, and the mounting frames 5 and the filter screen 6 are distributed in an L-shaped structure inside the outer shell 1.

[0031] The front of the outer casing 1 is equipped with a direct-blowing structure to deflect the wind direction.

[0032] The top of the mounting frame 5 is fixedly connected to an adsorption strip 7, and the top of the adsorption strip 7 is fixedly connected to a handle 8. Both the adsorption strip 7 and the handle 8 are designed as L-shaped structures. The bottom of the adsorption strip 7 and the top of the top plate 3 are attached to each other. The bottom of the adsorption strip 7 is provided with a magnet, and the adsorption strip 7 is adsorbed to the top of the top plate 3 by the magnet.

[0033] The housing 1 has two independent spaces inside, and the electrical control component 12 and the compressor component 13 are fixedly connected inside the right side of the housing 1. The electrical control component 12 and the compressor component 13 are separated from each other by a partition.

[0034] A fin 14 is fixedly connected to the inside of the left side of the outer shell 1. The fin 14 is distributed in an L-shape on the rear side of the inner side of the outer shell 1. The fin 14 is composed of metal sheets that are equidistantly distributed along the inner side of the outer shell 1.

[0035] Both ends of the fin 14 are provided with mounting rails 19, and each mounting rail 19 consists of two symmetrically distributed guide rails, and the inner side of each mounting rail 19 is slidably connected to the mounting frame 5.

[0036] Ventilation openings 17 are provided on the rear and left sides of the outer casing 1, and the ventilation openings 17 are aligned with the fins 14. A bracket 15 is provided inside the outer casing 1, and the upper and lower ends of the bracket 15 are fixedly connected to the bottom plate 2 and the top plate 3 respectively. A motor is fixedly connected in the middle of the bracket 15, and a fan 16 is fixedly connected to the output end of the motor.

[0037] A metal pipe 18 is fixedly connected inside the fin 14, and the metal pipe 18 is distributed in an S-shape inside the fin 14. Both ends of the metal pipe 18 are connected to the compressor assembly 13. Meanwhile, the fin 14 is located between two mounting frames 5.

[0038] During equipment use, the compressor assembly 13 will be in operation. The compressor assembly 13 draws in low-pressure, low-temperature refrigerant gas, and through compression, the pressure and temperature of the refrigerant are increased, transforming it into a high-temperature, high-pressure gas. The high-temperature, high-pressure refrigerant gas exchanges heat with the outside air through the metal pipe 18 and fins 14, and the outside air is driven by the fan 16 to blow over the fins 14, carrying away the heat in the refrigerant, causing the refrigerant temperature to drop and undergo a phase change, transforming it into a liquid state. The condensation process transforms the refrigerant from a gaseous state to a liquid state. Subsequently, the condensed liquid refrigerant flows through the pipe to the expansion valve of the indoor unit. The low-temperature, low-pressure refrigerant absorbs heat from the indoor air in the evaporator of the indoor unit, transforms back into a gaseous state, and is sent back to the compressor assembly 13, thus completing one cycle.

[0039] During the heat exchange process between the metal pipe 18 and the fins 14 and the outside air, the fan 16 blows outside air over the heat sink. At this time, the fan 16 will draw outside air into the housing 1 through the vent 17. As the outside air enters the housing 1, it will be filtered for the first time by the filter 6 located on the outside of the fins 14. After filtration, the air will flow inside the fins 14 to dissipate heat from the metal pipe 18 and remove the heat from the refrigerant. After the air flows through the fins 14, it will be filtered for the second time by the filter 6 on the inside of the fins 14, thereby achieving dust prevention treatment for the fins 14 and the inside of the housing 1.

[0040] The dust intercepted by the filter screen 6 will adhere to the filter screen 6. By pulling the handle 8 at the top of the adsorption strip 7, the handle 8 and the adsorption strip 7 will be separated from each other. Then, the adsorption strip 7 will drive the mounting frame 5 to slide upward in the mounting hole 4, so that the mounting frame 5 and the filter screen 6 will move upward. This will separate the dustproof structure formed by the mounting frame 5, the filter screen 6, the adsorption strip 7 and the handle 8 from the outer shell 1 and the top plate 3, making it easier to clean and replace the filter screen 6.

[0041] Example 2: Based on Example 1, a direct-blow protection structure is also disclosed, the specific structure of which is as follows:

[0042] The anti-direct-blow structure includes a guide groove 10 fixedly connected to the front side of the outer shell 1, and the outer shell 1 is provided with an opening, and a protective net 9 is fixedly connected inside the opening. The guide groove 10 is fixedly connected with guide strips 11 that are evenly distributed, and the ends of the guide strips 11 in the guide groove 10 all extend upward, and the protective net 9 is located inside the guide groove 10.

[0043] During the process of the fan 16 driving outside air to blow over the fins 14, the air will enter the interior of the housing 1 and be discharged from the interior of the housing 1 through the opening on the front side of the housing 1 and the protective net 9. Since the ends of the guide strips 11 of the guide groove 10 extend upward, when the air comes into contact with the guide groove 10 and the guide strips 11, the guide groove 10 and the guide strips 11 will guide the air to flow upward, preventing the air discharged by the air conditioner outdoor unit when it is installed at a low position from blowing directly on people and objects.
