Rotated in shape housing and be provided with moving block, the cavity volume of some both ends connections is provided with the moving block, the cavity volume both ends are equal
Strainer is provided with, silica-gel desiccant is arranged at intervals with some cavity volumes, has in the cavity volume of silica-gel desiccant and is equipped with
Heating wire, the moving block are connected with motor output shaft, and the first air intake blower fan, second gas are provided with first air flue
The second air intake blower fan, the motor, the heating wire, first air intake blower fan and the second inlet air wind are provided with road
Machine is respectively connected with control device；The distribution box includes two kinds of working statuses：1st, the first air intake blower fan operation, described second
Air intake blower fan is out of service, the motor at first air flue turn to the cavity volume with silica-gel desiccant with
First through hole connection, the motor at second air flue turn to the cavity volume with silica-gel desiccant with
Second through hole connects and starts the electric-heating-wire-heating；2nd, the second air intake blower fan operation, first air intake blower fan
Out of service, the motor at second air flue turns to the cavity volume and described first with silica-gel desiccant
Through hole connects, and the motor at first air flue turns to the cavity volume and described second with silica-gel desiccant
Through hole connects and starts the electric-heating-wire-heating；Two states are alternately.Using the structure in distribution box in use, described
One air intake blower fan is run, and second air intake blower fan is out of service, and the motor at first air flue turns to tool
The cavity volume for having silica-gel desiccant is connected with the first through hole, and the motor at second air flue turns to tool
The cavity volume for having silica-gel desiccant connects with second through hole and starts the electric-heating-wire-heating, under the state, the first gas
Silica-gel desiccant at road plays the role of dry air, and the silica-gel desiccant heating at the second air flue by moisture evaporation from the
Two through holes discharge aqueous vapor；After a period of time is run, the second air intake blower fan operation, first air intake blower fan stops fortune
OK, the motor at second air flue turns to the cavity volume with silica-gel desiccant and connects with the first through hole
Logical, the motor at first air flue turns to the cavity volume with silica-gel desiccant and connects with second through hole
To lead to and start the electric-heating-wire-heating, under the state, the silica-gel desiccant at the second air flue plays the role of dry air, and

Drying prescription, saves maintenance cost, prevents condensation in distribution box, prevents from climbing the generation of electricity, abnormal flashover electric discharge phenomena, improves distribution box
Security performance.
In above-mentioned technical proposal, it is preferred that the first humidity sensor is equipped with first air flue, in second air flue
Equipped with the second humidity sensor, first humidity sensor and second humidity sensor connect with the control device
Connect.First gas is entered by first humidity sensor and second humidity sensor detection using the structure
The air humidity in road and second air flue, working status is changed when humidity reaches certain value, so as to prevent from coagulating in distribution box
Dew, prevents from climbing the generation of electricity, abnormal flashover electric discharge phenomena, improves the security performance of distribution box.
In above-mentioned technical proposal, it is preferred that be equipped with the first temperature sensor in the babinet, the babinet is externally provided with second
Temperature sensor, it is described when the first temperature sensor detection temperature is higher than the second temperature sensor detection temperature
Distribution box performs another working status：First air intake blower fan and the one of operation of second air intake blower fan, positioned at institute
State the motor at the first air flue and at second air flue turn to the cavity volume with silica-gel desiccant with it is described
Second through hole connects.Using the structure by the first temperature sensor detection case body temperature, examined by second temperature sensor
Ambient air temperature is surveyed, when the first temperature sensor detection temperature is higher than the second temperature sensor detection temperature, at this time
Condition without condensation in babinet, thus need not with silica-gel desiccant adsorb vapor will not in babinet condensation, because
This, which performs above-mentioned working status, can save the energy.
Compared with prior art, the present invention have the advantages that：Using the structure during distribution box use, the
Temperature on one temperature sensor detection electric elements installation position, the environment of the external side of second temperature sensor detection detection case are empty
Temperature degree, three-temperature sensor detect the temperature of evaporator；The power of refrigerating plant is controlled by control device, so that
First temperature sensor detection temperature ＞ three-temperature sensors detection temperature >=second temperature sensor detection temperature, at this time ring
Border air has steam when passing through evaporator and is condensed in spirality channel, and air passes through spiral element during air inlet
Road produces centrifugal force and can adhere to dust on condensed water, and condensed water, which is built up, in spirality channel spills into check valve
Top is entered in water storage cavity volume by check valve, so as to prevent water shortage in water storage cavity volume, and passes through condenser in water storage cavity volume
And the heat heat exchange that electric elements are sent, rejecting heat in the water in water storage cavity volume so that tank surface temperature raises,
So as to prevent that condensation, condenser and electric elements can generate heat, make in electric elements during the work time everywhere on babinet
If disclosure satisfy that during, the first temperature sensor detection temperature ＞ three-temperature sensors detection temperature >=second temperature passes
In the case of sensor detection temperature, the i.e. controllable refrigerating plant of control device is closed, so that the energy is saved, can using the device
It is anti-condensation, while can prevent that excessive realize of temperature is radiated at electric elements, while prevent dust from entering during air inlet
Into babinet.
