Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to an anti-clogging refrigeration and air conditioning device. Background Technology

[0002] An air conditioner, or air conditioner, consists of four parts: a refrigeration (heating) cycle system, an air circulation and ventilation system, an electrical control system, and a housing. It is a small air conditioning unit that maintains a certain temperature, humidity, airflow speed, cleanliness, and freshness of the air in the conditioned space. The compressor compresses the gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then sent to the condenser (outdoor unit) to dissipate heat and become a room-temperature, high-pressure liquid refrigerant (hence the hot air blown out by the outdoor unit). The refrigerant then enters the evaporator (indoor unit) through a capillary tube. As the space suddenly increases and the pressure decreases after the refrigerant reaches the evaporator from the capillary tube, the liquid refrigerant vaporizes and becomes a low-temperature gaseous refrigerant, thus absorbing a large amount of heat. The evaporator then cools down, and the indoor unit's fan blows indoor air through the evaporator, resulting in cold air being blown out by the indoor unit.

[0003] The following problems exist in the air conditioning cooling process: 1. Dust gets into the pipes during the cooling process, and the pipes will become blocked after long-term use; 2. It is difficult to replace the blocked pipes, and the replacement increases the maintenance cost. Therefore, a blockage-proof air conditioning equipment is being developed. Utility Model Content

[0004] This utility model proposes an anti-clogging refrigeration and air conditioning device, which solves the problem in related technologies that dust gets mixed into the pipes during the refrigeration process, and the pipes will become blocked after long-term use.

[0012] As a further technical solution, the transmission ratio between the driven tooth and the meshing tooth is 1:1, the cleaning frame and the connecting disc are both circular structures, and the diameters of the cleaning frame and the connecting disc are matched.

[0013] As a further technical solution, the cleaning frame and the connecting pipe are movably connected by a bearing, and a flow hole is opened at the center of the cleaning frame.

Detailed Implementation

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-4 As shown, this embodiment proposes an anti-clogging refrigeration and air conditioning device, including...

[0029] Pipe box 1, with connecting pipes 2 installed on opposite sides of pipe box 1;

[0030] The screw cleaning assembly 3 is installed inside the pipe box 1 and the connecting pipe 2;

[0031] Limit linkage component 4 is installed inside pipe box 1;

[0032] The rotary cleaning assembly 3 includes a knob 3-1, a portion of which is inserted into the pipe box 1. A connecting plate 3-2 is provided at the bottom of the knob 3-1, and a scraper 3-3 is provided at the bottom of the connecting plate 3-2. The scraper 3-3 is in contact with the inner wall of the pipe box 1. A cleaning frame 3-4 is provided inside the connecting pipe 2, and a cleaning blade 3-5 is provided on the side wall of the cleaning frame 3-4. The cleaning blade 3-5 is in contact with the inner wall of the connecting pipe 2.

[0033] In this embodiment, after the knob 3-1 is rotated, the connecting plate 3-2 rotates, which in turn drives the scraper 3-3 to rotate, thereby cleaning the inner wall of the pipe box 1 and preventing dust from accumulating. When the cleaning rack 3-4 inside the connecting pipe 2 rotates, the cleaning blade 3-5 also cleans the inner wall of the connecting pipe 2.

[0034] Specifically, the bottom of the pipe box 1 is provided with a cleaning port 3-6, and the opposite sides of the pipe box 1 are provided with connecting ports 3-7. The connecting pipe 2 is sealed and inserted into the connecting port 3-7.

[0035] In this embodiment, the cleaning port 3-6 is in a blocked state during use. The cleaning port 3-6 can remove the dust that falls after cleaning. The connecting port 3-7 is used to connect the pipe box 1 and the connecting pipe.

[0036] Furthermore, the limiting linkage component 4 includes a limiting piece 4-1, which is disposed on the rotating connecting plate 3-2. A limiting ring groove 4-2 is provided on the inner surface of the pipe box 1, and the limiting piece 4-1 is embedded inside the limiting ring groove 4-2. A meshing tooth 4-3 is provided at the edge of the connecting plate 3-2, and a driven tooth 4-4 is provided on one side of the cleaning frame 3-4. The meshing tooth 4-3 and the driven tooth 4-4 mesh with each other.

[0037] In this embodiment, the limiting piece 4-1 is embedded in the limiting ring groove 4-2 and rotates smoothly. When the meshing teeth 4-3 on the connecting plate 3-2 rotates, it drives the driven teeth 4-4 to rotate as well, thereby realizing that the wall scraper 3-3 and the cleaning knife 3-5 rotate at the same time to clean the inner wall of the pipe box 1 and the connecting pipe 2.

[0038] Furthermore, the transmission ratio between the driven tooth 4-4 and the meshing tooth 4-3 is 1:1, and both the cleaning frame 3-4 and the connecting disc 3-2 are circular structures, with the diameters of the cleaning frame 3-4 and the connecting disc 3-2 matching.

[0039] In this embodiment, after manually turning the knob 3-1, the driven tooth 4-4 and the meshing tooth 4-3 are in a synchronized state, so that the cleaning knife 3-5 and the wall scraping knife 3-3 rotate synchronously.

[0040] Furthermore, the cleaning frame 3-4 is movably connected to the connecting pipe 2 via a bearing. A flow hole 5 is opened at the center of the cleaning frame 3-4. A rotating disc 6 is provided at the upper end of the knob 3-1. The knob 3-1 is movably connected to the pipe box 1 via a bearing. There are 3 scraper blades 3-3. The outer side of the scraper blades 3-3 is fitted to the pipe box 1. The pipe box 1 has a cylindrical structure. The upper and lower ends of the pipe box 1 are connected by semi-circular joints.

[0041] In this embodiment, the flow hole 5 is used for air flow.

[0042] Furthermore, both the wall scraper 3-3 and the cleaning blade 3-5 have triangular cross-sections. The bottom of the wall scraper 3-3 is provided with a cleaning cavity, which corresponds to the position of the cleaning port 3-6. Both the meshing tooth 4-3 and the driven tooth 4-4 are 45° inclined surfaces. The cleaning frame 3-4 and the connecting plate 3-2 are perpendicular to each other. There are two connecting pipes 2 and two cleaning frames 3-4. Each cleaning frame 3-4 is equipped with three cleaning blades 3-5, and the multiple cleaning blades 3-5 are evenly distributed on the side wall of the cleaning frame 3-4.

[0043] In this embodiment, the cleaning cavity is used for the accumulation of scraped-off dust, and the rotating disc 6 is more convenient for manual rotation.

[0044] When cleaning of the air conditioning pipes is required, rotating the knob 3-1 causes the connecting plate 3-2 to rotate, which in turn causes the scraper 3-3 to rotate, thereby cleaning the inner wall of the pipe box 1 and preventing dust accumulation. When the cleaning rack 3-4 inside the connecting pipe 2 rotates, the cleaning blade 3-5 also cleans the inner wall of the connecting pipe 2. The limiting plate 4-1 is embedded in the limiting ring groove 4-2 and rotates smoothly. When the meshing teeth 4-3 on the connecting plate 3-2 rotates, it causes the driven teeth 4-4 to rotate accordingly, thus realizing that the scraper 3-3 and the cleaning blade 3-5 rotate simultaneously to clean the inner walls of the pipe box 1 and the connecting pipe 2.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
