As shown in fig. 1 and 2, the application provides an energy-saving fan 1 self-cleaning air conditioning unit, which comprises necessary components of the air conditioning unit such as a fan 1, an evaporator 2, a condenser 3 and the like, and also comprises an energy storage tank 4, a condenser heat exchange tube 5, an evaporator heat exchange tube 6, a liquid collecting tank 7, a liquid storage tank 8 and an atomization nozzle 9;
the energy storage tank 4 is insulated and internally filled with heat exchange medium, and the energy storage tank 4 is communicated with the condenser heat exchange tube 5 and the evaporator heat exchange tube 6, so that the heat exchange medium can flow inside the energy storage tank 4, the condenser heat exchange tube 5 and the evaporator heat exchange tube 6;

The heat exchange medium is preferably brine with a certain concentration, mainly because brine has low cost and lower solidifying point, so that the heat exchange medium cannot be frozen and solidified when flowing through the surface of the low-temperature evaporator 2, and the heat exchange tube 6 of the evaporator is blocked.
The pipelines of the condenser heat exchange tube 5 and the condenser 3 and the pipelines of the evaporator heat exchange tube 6 and the evaporator 2 can be fixed together in a multi-layer staggered lamination mode, namely, the pipelines of the condenser heat exchange tube 5 and the condenser 3 are coiled into a plate shape or a sheet shape in a roundabout way and are fixed together in a lamination mode, and multiple layers are repeatedly stacked in the mode, so that the pipelines of the condenser heat exchange tube 5 and the condenser 3 are laminated and alternated mutually between the layers, the contact area between the two is further increased by a compression space, and the heat exchange efficiency is increased; the evaporator heat exchange tube 6 achieves the same effect by adopting the coiling mode as the pipeline of the evaporator 2.
So when condenser 3 during operation heat transfer medium circulates between the pipeline of condenser 3 through condenser heat transfer pipe 5, on the one hand can help condenser 3 cooling, on the other hand can absorb the temperature that condenser 3 released and make self temperature rise, after high temperature heat transfer medium backward flow to energy storage jar 4 inside, can improve the whole temperature of energy storage jar 4 inside heat transfer medium again, and then store the energy that condenser 3 released.
In addition, after the whole device works for a long time, one layer of ice crystals can be condensed on the surface of the evaporator 2, at the moment, the high-temperature heat exchange medium in the energy storage tank 4 is conveyed to the evaporator heat exchange tube 6, and the flowing high-temperature heat exchange medium releases heat energy to the surface of the evaporator 2, so that ice crystals on the surface of the evaporator 2 can be promoted to melt, and compared with the traditional heating wire heating defrosting, the scheme invokes the heat originally released by the condenser 3 in the device to replace the heating wire to work, and further improves the energy utilization rate of the whole device.
On the other hand, the application sets a liquid collecting tank 7 at the bottom of the evaporator 2 for collecting the ice crystal melting water and storing the ice crystal melting water in a liquid storage tank 8 so as to take the ice crystal melting water in the liquid storage tank 8 as a water source at a proper time and spray the ice crystal melting water to the surface of the fan 1 in the form of water mist through an atomization nozzle 9, on one hand, the water mist can neutralize static electricity on the surface of the fan 1 and reduce dust adhesion in air, on the other hand, the water mist gathers as water drops on the surface of the fan 1, the water drops can combine the dust adhered on the surface of the fan 1 and are thrown out in the rotating process of the fan 1, and the purpose of cleaning the surface of the fan 1 is achieved.
In addition, the water mist is sprayed on one side of the air inlet of the fan 1 and is positioned near the condenser 3, so that the water mist can move towards the surface of the fan 1 under the action of air flow, and the water mist can evaporate and absorb the temperature of air near the condenser 3, so that the cooling efficiency of the condenser 3 is improved.
According to the application, the annular circulation passages are required to be established between the condenser heat exchange tube 5 and the evaporator heat exchange tube 6 and the energy storage tank 4, so that the flow of heat exchange media between the heat exchange tubes is facilitated, and further the heat exchange is realized.
Further, two communicating parts are respectively arranged between the condenser heat exchange tube 5 and the evaporator heat exchange tube 6 and the energy storage tank 4, so that an annular passage is formed between the condenser heat exchange tube 5 and the evaporator heat exchange tube 6 and the energy storage tank 4, and heat exchange medium can flow unidirectionally in the condenser heat exchange tube 5 or the evaporator heat exchange tube 6 and circulate between the condenser heat exchange tube 5 and the energy storage tank 4 or between the evaporator heat exchange tube 6 and the energy storage tank 4.
The application considers that the unidirectional flowing heat exchange medium can more guide the heat on the surface of the condenser 3 to flow to the energy storage tank 4, and is more beneficial to outputting the heat in the energy storage tank 4 to the surface of the evaporator 2, so that a driving element is required to start the driving action on the flow of the heat exchange medium in the passage.
Further, a first unidirectional pump 11 is arranged at the communication part of the condenser heat exchange tube 5 and the energy storage tank 4, and the heat exchange medium can flow unidirectionally in the condenser heat exchange tube 5 and circulate in the condenser heat exchange tube 5 and the energy storage tank 4 under the drive of the first unidirectional pump 11;
the communication part of the evaporator heat exchange tube 6 and the energy storage tank 4 is provided with a second unidirectional pump 12, and the heat exchange medium can flow unidirectionally in the evaporator heat exchange tube 6 and circulate in the evaporator heat exchange tube 6 and the energy storage tank 4 under the drive of the second unidirectional pump 12.
The application considers that when the evaporator 2 works normally, the heat exchange medium is not easy to exist in the evaporator heat exchange tube 6, otherwise, the heat exchange medium can be solidified and crystallized under the continuous low temperature effect of the surface of the evaporator 2, so that the evaporator heat exchange tube 6 is blocked.
Further, the second unidirectional pump 12 drives the flow direction of the liquid to face the inside of the energy storage tank 4, the electromagnetic valve 13 is arranged at the liquid inlet position of the evaporator heat exchange tube 6 relative to the energy storage tank 4, and the electromagnetic valve 13 can switch a communicating object of the evaporator heat exchange tube 6 at the position, wherein the communicating object is the energy storage tank 4 or the atmosphere;
therefore, when the evaporator 2 is frosted, the electromagnetic valve 13 is communicated with the heat exchange medium in the energy storage tank 4, under the action of the second unidirectional pump 12, the heat exchange medium firstly extrudes the air in the original hollow evaporator heat exchange tube 6 into the energy storage tank 4, and then outputs heat in the evaporator heat exchange tube 6 for defrosting, when the defrosting is finished, the electromagnetic valve 13 interrupts the communication between the evaporator heat exchange tube 6 and the energy storage tank 4, and enables the evaporator heat exchange tube 6 to be communicated with the atmosphere, and the second unidirectional pump continuously works, so that the outside atmosphere can refill the whole evaporator heat exchange tube 6, the heat exchange medium participated in the evaporator heat exchange tube 6 is extruded into the energy storage tank 4, and after the evaporator heat exchange tube 6 is re-hollowed, the second unidirectional pump 12 stops operating.
According to the application, in the scheme, gas flows into the energy storage tank 4 in the process that the heat exchange medium flows into the evaporator heat exchange tube 6 and the heat exchange medium flows out of the evaporator heat exchange tube 6, and meanwhile, as the heat exchange medium absorbs the heat released by the condenser 3, the temperature in the energy storage tank 4 is increased to cause the expansion of the air volume in the energy storage tank 4, so that the high pressure in the energy storage tank 4 is caused.
Further, the top of the energy storage tank 4 is provided with a pressure relief opening 14, and the pressure relief opening 14 is used for guiding out redundant gas in the energy storage tank 4.
In addition, the application considers that dust is mixed with the liquid collecting tank 7 and the evaporator 2 after long-term use, and if the dust enters the liquid storage tank 8 along with ice crystal melting water and flows to the atomizing nozzle 9, the atomizing nozzle 9 is easy to be blocked.
Further, a layer of filter screen 15 is fixed above the liquid outlet 10, and the filter screen 15 is used for preventing dust in the liquid collecting tank 7 and on the surface of the evaporator from being mixed in ice crystal melting water and flowing into the liquid storage tank 8, so that the communication port inside the liquid storage tank 8 is prevented from being blocked by the dust.
Meanwhile, the filter screen 15 also has a cleaning requirement because the filter screen 15 can collect dust on its surface while filtering dust, thereby blocking the filter holes.
Further, a cleaning brush 16 is arranged above the filter screen 15, and the cleaning brush 16 can scratch the surface of the filter screen 15 at random, so that dust on the surface of the filter screen 15 is cleaned.
The cleaning mode of the cleaning brush 16 on the filter screen 15 can adopt a mode of rotating the brush body to make the brush head scratch the surface of the filter screen 15 reciprocally, so as to clean the filter screen 15, and the specific design is as follows.
Further, the middle part of the cleaning brush 16 is a disc-shaped rotator, the rotation center of the disc-shaped rotator is rotationally connected to the inner wall of the machine body above the filter screen 15, the brush body of the cleaning brush 16 is composed of soft hairs, the soft hairs extend outwards perpendicular to the lateral surface of the disc-shaped rotator, and when the cleaning brush 16 rotates, the top of the soft hairs can scratch the surface of the filter screen 15.
The driving force for the rotation of the cleaning brush 16 may be derived from the above gas which is increased from time to time inside the tank 4, and when the surplus gas inside the tank 4 is discharged from the pressure relief port 14, the discharged gas may be used as power to drive the cleaning brush 16.
Further, the cleaning brush 16 is driven by a pneumatic motor 17 connected with a side instrument, an air inlet of the pneumatic motor 17 is communicated with the pressure relief opening 14, and the air overflowed from the pressure relief opening 14 can push a rotor inside the pneumatic motor 17 to rotate and drive the cleaning brush 16 to rotate.
Considering that the energy storage tank 4 needs to store the heat taken from the condenser 3 so as to be output to the evaporator 2 at an appropriate time, it needs to have a heat-retaining capability.
Further, the energy storage tank 4 comprises a shell 18 and an inner container 19, and a vacuum layer 20 is arranged in the middle of the shell 18 and the inner container 19.
Wherein the vacuum layer 20 can reduce the heat loss of the heat exchange medium inside the energy storage tank 4 in the storage state.
