[0002] Air conditioner evaporator is an important component in air conditioning system, its main role is to utilize the evaporation characteristics of refrigerant at low pressure to absorb the heat of indoor, to realize refrigeration effect.In refrigeration cycle, liquid refrigerant is evaporated into gaseous state when absorbing the heat of indoor air, so that the temperature of indoor will drop.

[0003] Through the retrieval, Chinese patent application No. CN201610768274.4 discloses an automobile air conditioner evaporator, comprising a heat exchange module, the heat exchange module comprises an upper air chamber and a lower air chamber, the upper air chamber and the lower air chamber are communicated by a plurality of porous flat tubes, fins are arranged between adjacent porous flat tubes, and a half partition plate is arranged in the middle of the upper air chamber and the lower air chamber. The invention has the following advantages: 1. The evaporating chamber of the parallel flow evaporator provided by the invention can prevent incorrect installation during installation process, improve installation efficiency, and prevent misalignment of the liquid inlet chamber and the gas outlet chamber to a certain extent; 2.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] Please refer to Figures 1-6 The utility model provides a technical scheme:

[0029] A kind of evaporimeter, comprising:

[0030] The main body 1 of evaporimeter, the main body 1 includes shell and fin in shell, copper pipe 2 is installed on the main body 1, the air inlet face of shell is integrally formed with retaining ring 3;

[0031] Further include the dustproof mechanism being arranged in retaining ring 3;Dustproof mechanism includes dustproof net plate 4 and rubber ring 5, dustproof net plate 4 is clamped in retaining ring 3, and the contact surface of dustproof net plate 4 and retaining ring 3 inner wall is provided with rubber ring 5, and the both sides frame of dustproof net plate 4 is provided with handle 6;

[0032] The positioning mechanism is used for positioning the dust screen plate 4, and comprises inclined blocks 9 slidably inserted into the blocking ring 3. The two groups of inclined blocks 9 are symmetrically arranged on both sides of the blocking ring 3, and the inclined surfaces of the inclined blocks 9 face the air inlet surface of the main body 1. One end of each inclined block 9 is provided with a limiting plate 13, and the outer wall of the limiting plate 13 is provided with a connecting rod 10. The outer wall of the blocking ring 3 is further provided with a Z-shaped plate 11, the connecting rod 10 is slidably inserted into the Z-shaped plate 11, and the connecting plates 12 are arranged between the end portions of the two groups of connecting rods 10 on the same side of the blocking ring 3. The connecting rod 10 is sleeved with a compression spring 14 between the limiting plate 13 and the inner wall of the Z-shaped plate 11, and the outer wall of the connecting plate 12 is provided with a pulling block 15.

[0033] In use, the air contacts the main body 1 of the evaporator through the dust screen plate 4 in the blocking ring 3, and cooperates with the external filter screen, so that the double filtering function is realized, thereby reducing the possibility of dust contacting the evaporator, avoiding the influence of dust accumulation on the heat exchange efficiency of the evaporator, and ensuring the performance of the air conditioning system and the air quality in the room.

[0034] When the dust screen plate 4 is installed, the rubber ring 5 is arranged on the inner wall of the blocking ring 3, and then the dust screen plate 4 is pressed into the blocking ring 3 through the hand-held handle 6. Since the inclined surfaces of the inclined blocks 9 face outward, and the compression spring 14 is arranged on the connecting rod 10 on one side of the inclined block 9, the frame of the dust screen plate 4 can be easily pressed into the blocking ring 3 when the frame contacts the inclined block 9, so that the installation of the dust screen plate 4 is completed. After the inclined block 9 is reset, the dust screen plate 4 can be positioned to avoid disengagement.

[0035] When the dust screen plate 4 is removed, the inclined block 9 is retracted by pulling the pulling block 15, so that the locking of the dust screen plate 4 is released, and the dust screen plate 4 can be taken out through the handle 6, thereby facilitating the cleaning and replacement of the dust screen plate 4.

[0036] The filtering material of the dust screen plate 4 is HEPA filter screen material. The HEPA high-efficiency filter screen has a removal efficiency of more than 99.7% for particles with a diameter of 0.3 microns (1 / 200 of the diameter of hair), and is the most effective filtering medium for smoke, dust, bacteria and other pollutants.

[0037] Further, please refer to Figures 3-4 :

[0038] One side of the rubber ring 5 is integrally formed with a protrusion 7, and the inner wall of the blocking ring 3 is provided with a sealing groove 8 corresponding to the protrusion 7.

[0039] After the installation of the dust screen plate 4 is completed, the frame of the dust screen plate 4 and the inner wall of the blocking ring 3 have good sealing performance under the cooperation of the rubber ring 5, the boss and the sealing groove 8, so that the air can only contact the main body 1 of the evaporator after passing through the dust screen plate 4.

[0040] For further details, please refer to Figures 4-6 :

[0041] A threaded hole 16 is provided on the inclined surface of the inclined block 9. A positioning screw 17 is installed in the internal thread of the threaded hole 16. A knob is provided at one end of the positioning screw 17, and the other end of the positioning screw 17 abuts against the edge surface of the dustproof mesh plate 4 after passing through the threaded hole 16.

[0042] By opening a threaded hole 16 on the inclined surface of the inclined block 9, after the dustproof mesh plate 4 is installed, the positioning screw 17 is installed inside the threaded hole 16 by turning the knob, and the end of the positioning screw 17 presses against the edge of the dustproof mesh plate 4. This design can make the connection between the dustproof mesh plate 4, the rubber ring 5 and the retaining ring 3 tighter, improving the sealing performance and dustproof performance. On the other hand, the positioning screw 17 can lock the position of the dustproof mesh plate 4 to prevent the dustproof mesh plate 4 from falling off and shaking.

[0043] When it is necessary to remove the dustproof mesh 4, simply rotate the knob to remove the positioning screw 17.

[0044] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
