The shell is equipped with insulating layer.The loss for avoiding cold is arranged in this, improves the utilization rate of cold.
The course of work of this intelligence cold-storage domestic fan is as follows：
(1) cold-storage works：
When cold-storage works, the second relay output control instruction of control terminal drives the second water pump, the output of third relay
Control instruction drives semiconductor chilling plate, the 4th relay to export control instruction and drive cooling fan；Meanwhile the of cold-storage water tank
Two temperature sensors acquire the temperature of water storage in cold-storage water tank, then by third interface to singlechip feedbsck.
The control of water storage temperature in cold-storage water tank：According to the water storage temperature of second temperature sensor detection and water storage setting temperature
Difference between degree controls the start-stop of the second water pump, semiconductor chilling plate and cooling fan, realizes the control of water storage temperature.Work as storage
When coolant-temperature gage is less than or equal to -1 DEG C of water storage set temperature, the second water pump, semiconductor chilling plate and cooling fan are stopped, no
Cool down again to water storage；When water storage temperature is greater than or equal to+1 DEG C of water storage set temperature, the second water pump, semiconductor chilling plate and dissipate
Air-heater, which opens work, reduces water storage temperature, and water storage temperature is made to be eventually held within water storage set temperature ± 1 DEG C.
Opening sequence between second water pump, semiconductor chilling plate and cooling fan：Cooling fan is first opened, is delayed 10 seconds
Open semiconductor chilling plate and the second water pump.It is to give heat dissipation aluminium block precooling first to open cooling fan.Second water pump, semiconductor
Stopping sequence between cooling piece and cooling fan：First stop semiconductor chilling plate, is delayed 10 seconds and stops cooling fan and second
Water pump, it is to dissipate waste heat to heat dissipation aluminium block that delay, which stops cooling fan, and it is to take away semiconductor that delay, which stops the second water pump,
The cold of cooling piece cold end allows the raising of its temperature to be unlikely to surface sweating.
(2) air-supply work：
When air-supply work, the first relay output control instruction driving pressure fan, speed adjusting module and the speed change water of control terminal
It pumps (i.e. the first water pump), while the first temperature sensor acquires the air outlet temperature of shell, then by second interface to microcontroller
Feedback.
The air outlet temperature control at air-supply end：It is set with air outlet according to the air outlet temperature of the first temperature sensor detection
Difference between temperature, speed adjusting module export different voltage, to adjust the rotating speed of velocity fluctuation pump, to realize air outlet temperature
Control.When air outlet temperature is greater than or equal to+5 DEG C of air outlet set temperature, velocity fluctuation pump full speed operation；Work as air outlet
When temperature is less than+5 DEG C of air outlet set temperature, speed governing works velocity fluctuation pump in proportion.After being reduced because of air outlet temperature, no longer need
Cold that will be too big, reduces the rotating speed of velocity fluctuation pump, water velocity also reduces, unit interval water flow in the bronze pan tube at end of blowing
It reduces, the final cold for blowing end is also reduced, otherwise after air outlet temperature increases, need to promote the rotating speed of velocity fluctuation pump, final to increase
The cold for adding air-supply end realizes the function of air-supply end cold automatic adjustment.
Stopping sequence between velocity fluctuation pump and pressure fan：First stop velocity fluctuation pump, be delayed 10 seconds out-of-blast machines, delay
Out-of-blast machine is to allow the raising of its surface temperature to be unlikely to condense to take away the cold of bronze pan tube and aluminum fin-stock.
(3) co-ordination：
At work, driving refrigeration end is remotely controlled by smart mobile phone, allows water recycle stream between cold-storage water tank and refrigeration end
Dynamic, refrigeration end refrigeration heat absorption makes the water storage temperature in cold-storage water tank reduce, and by water storage temperature control water storage set temperature ±
Within 1 DEG C.Then operation air-supply end and velocity fluctuation pump, allow cold water to be circulated between air-supply end and cold-storage water tank, cold water stream
Through blow end bronze pan tube when, cold water with air-supply end send out wind carry out heat exchange, then from the air outlet of shell flow out wind-warm syndrome
Degree reduces.Because air-supply end and the water storage of cold-storage water tank before velocity fluctuation pump work have reached lower temperature, can be sent out at air-supply end
The wind of lower temperature, the water storage temperature rise of cold-storage water tank after the work of air-supply end, when water storage temperature is set greater than or equal to water storage
When+1 DEG C of constant temperature degree, refrigeration end works on the second water pump makes water storage supplement cold, final to blow end sustainable a period of time
The wind for sending out lower temperature, reaches human comfort's effect.
Above-mentioned specific implementation mode is the preferred embodiment of the utility model, can not be defined to the utility model,
Other any changes made without departing from the technical solution of the utility model or other equivalent substitute modes, are included in
Within the scope of protection of the utility model.
