[0019] The following will be described in detail in combination with the accompanying Figure 1 - Figure 4 The present application will be further described in detail.

[0020] Embodiment I:

[0021] A total heat exchanger with a dust prevention structure for air conditioning, referring to Figure 1 - Figure 4The utility model provides an air -conditioning has the full heat exchanger of dust -proof structure, including shell 1 and dust falls subassembly shell 1's inside equal interval is installed with multiple heat exchange pipes 2, the outside sliding connection of heat exchange pipe 2 has annular dust -wiping hoop 3, the inner wall of shell 1 is fixedly connected with servo motor 4, the output of servo motor 4 is fixedly connected with lead screw 5 through coupling, the outside of lead screw 5 is connected with sliding block 6, and the one side of sliding block 6 is fixedly connected with adjusting plate 7, and multiple annular dust -wiping hoop 3 are all fixedly connected in the outside of adjusting plate 7, when the full heat exchanger works, air carries out heat exchange in shell 1 through heat exchange pipe 2, when air flows on the surface of heat exchange pipe 2, dust and other impurities are easy to adhere on heat exchange pipe 2, to solve this problem, annular dust -wiping hoop 3 is arranged outside heat exchange pipe 2, when needing to clean dust, start the fixedly connected servo motor 4 of shell 1 inner wall, and the output of servo motor 4 drives lead screw 5 to rotate through coupling, because the outside of lead screw 5 is connected with sliding block 6, according to the screw nut transmission principle, the rotation of lead screw 5 will make sliding block 6 move along the axial direction of lead screw 5. The adjusting plate 7 of one side fixedly connected sliding block 6 will also move, and multiple annular dust -wiping hoop 3 are all fixedly connected in the outside of adjusting plate 7, so the movement of adjusting plate 7 will drive annular dust -wiping hoop 3 to slide on heat exchange pipe 2, to scrape the dust on the surface of heat exchange pipe 2.

[0022] With reference to Figure 2 , dust falls subassembly includes the rectangular groove 8 of setting in the bottom of shell 1, and multiple interval rods 9 are fixedly connected in the inside equal interval of rectangular groove 8, after annular dust -wiping hoop 3 scrapes the dust on the surface of heat exchange pipe 2, the dust will drop down. Rectangular groove 8 is located at the bottom of shell 1, provides a space for the dust of centralized drop and collection, interval rod 9 plays the role of support on one hand, guarantees the stability of the structure of rectangular groove 8, on the other hand, there is a certain gap between interval rod 9, so that the dust can pass through the gap and fall down from rectangular groove 8 smoothly, avoids the dust to accumulate in rectangular groove 8.

[0023] With reference to Figure 1 , the outside wall of shell 1 is provided with a slot, and an observation window 10 is installed in the slot of shell 1. When the full heat exchanger is running, the operator can directly observe the inside of the shell 1 through the observation window 10, such as observing the dust accumulation degree on the surface of the heat exchange pipe 2, judging whether to start the cleaning device; Also can observe the running state of each part, such as the running state of servo motor 4, so as to find out the problems in the running process of the equipment in time, and maintain and handle in time, to ensure the normal operation of the full heat exchanger.

[0024] With reference to Figure 1 And Figure 2The top of the shell 1 is fixedly connected with a horizontal plate 11, and two mounting holes 12 are formed in the interior of the horizontal plate 11. When the total heat exchanger is installed, the horizontal plate 11 can be fixed at a specified installation position, such as a wall, a ceiling or other equipment support, by using connecting members such as bolts and nuts through the mounting holes 12, and the design of the two mounting holes 12 can ensure the stability of the installation of the total heat exchanger.

[0025] The working principle of the total heat exchanger with a dustproof structure for an air conditioner according to the embodiment is as follows: the servo motor 4 is preferably of HBS57 type, and the servo motor 4 is electrically connected with an external power source through a switch. When the total heat exchanger is installed, the horizontal plate 11 can be fixed at a specified installation position, such as a wall, a ceiling or other equipment support, by using connecting members such as bolts and nuts through the mounting holes 12, and the design of the two mounting holes 12 can ensure the stability of the installation of the total heat exchanger. When the total heat exchanger is working, air exchanges heat in the shell 1 through the heat exchange pipes 2. The heat exchange pipes 2 are electrically connected with an external power source through a switch. When air flows on the surface of the heat exchange pipes 2, dust and other impurities are easily attached to the heat exchange pipes 2. To solve this problem, the annular dust scraping hoops 3 are arranged outside the heat exchange pipes 2. When it is necessary to clean dust, the servo motor 4 fixedly connected to the inner wall of the shell 1 is started through the switch. The output end of the servo motor 4 drives the screw rod 5 to rotate through a coupling. Since the screw rod 5 is externally threadedly connected with the sliding block 6, according to the screw rod and nut transmission principle, the rotation of the screw rod 5 will make the sliding block 6 move along the axial direction of the screw rod 5. The self-locking condition can be calculated by the following formula: self-locking condition = friction coefficient x tan (screw angle) ≥ 1. The angle at which the threads of the screw rod 5 are formed is 20 degrees. The adjusting plate 7 fixedly connected to one side of the sliding block 6 will also move. Since the plurality of annular dust scraping hoops 3 are fixedly connected to the outside of the adjusting plate 7, the movement of the adjusting plate 7 will drive the annular dust scraping hoops 3 to slide on the heat exchange pipes 2, so as to scrape off the dust on the surface of the heat exchange pipes 2. The operator can directly observe the situation inside the shell 1 through the observation window 10, such as observing the dust accumulation degree on the surface of the heat exchange pipes 2 to determine whether it is necessary to start the cleaning device. The running state of each component, such as the operation of the servo motor 4, can also be observed, so as to timely find problems occurring in the running process of the equipment, and timely maintain and handle the problems, to ensure the normal running of the total heat exchanger.
