Referring to fig. 1 and 2, the utility model discloses an intermittent drying and dehumidifying device, which comprises a drying and dehumidifying box 1, wherein the drying and dehumidifying box 1 is provided with a fresh air inlet 2, a humid air inlet 3 and a humid air outlet 4, a controller 5, a temperature and humidity sensor 11 connected with the controller 5, a dehumidifying drier 6, a three-way electromagnetic valve 7, a pipeline fan 8 and a two-way electromagnetic valve 9 are arranged in the drying and dehumidifying box 1, and a valve hole I of the three-way electromagnetic valve 7 is communicated with the humid air inlet 3; a valve hole II of the three-way electromagnetic valve 7 is communicated with the inner space of the drying and dehumidifying box 1; a valve hole III of the three-way electromagnetic valve 7 is communicated with the moist air outlet 4, and a valve port I of the two-way electromagnetic valve 9 is communicated with the fresh air inlet 2 through a pipeline fan 8; and a second valve port of the two-way electromagnetic valve 9 is communicated with the inner space of the drying and dehumidifying box 1.

In the structure, the controller 5, the temperature and humidity sensor 11, the dehumidification dryer 6, the three-way electromagnetic valve 7, the pipeline fan 8 and the two-way electromagnetic valve 9 are purchased standardized components, the installation and maintenance are more convenient and humanized due to the modular design, and the two-way electromagnetic valve 9 is a two-position two-way direct-acting electromagnetic valve. The three-way electromagnetic valve 7 is a two-position three-way stop type electromagnetic valve, because the valve hole I and the valve hole III need to be controlled independently.

Preferably, an ac contactor 10 is installed in the drying and dehumidifying box 1, the controller 5 controls the dehumidifying dryer 6 through the ac contactor 10, and the dehumidifying dryer 6 has high power and high current, so that it needs to be controlled through the ac contactor 10, and the duct fan 8 is a micro duct fan 8.

As shown in the figure, the drying and dehumidifying box 1 comprises a box body 12 and a box cover 13 hinged with the box body 12 through a hinge, a quick clamp 14 for locking the box cover 13 is arranged between the box cover 13 and the box body 12, and the structure is convenient for later maintenance and installation.

The working principle of the application is briefly described as follows: when in actual use, the moist air inlet 3 is communicated with a closed space (to-be-dried box) needing dehumidification; the dehumidifying dryer 6 in the device absorbs the moisture in the air nearby to gradually reduce the air humidity of the communication space in the whole box body 12. With the continuous infiltration of external moisture, the moisture absorbed in the dehumidifying dryer 6 gradually tends to be saturated, and the humidity in the box also gradually rises; when the humidity reaches the upper limit set by the controller 5, the controller 5 is started, the power supply is switched on, the dehumidifying dryer 6 starts to heat, and the moisture absorbed in the dehumidifying dryer 6 is evaporated; and meanwhile, the valve hole is closed to prevent the evaporated water vapor from flowing back into the box body 12 to be dried. Meanwhile, the micro pipeline fan 8 is started; the first valve port is communicated with the air outside the lead-in box; the valve hole III is communicated with the water vapor discharged by evaporation. After hours of work, the dehumidification box is heated and evaporated in the way, and the inside and the outside circulate, so that all the moisture absorbed before the dehumidification drier 6 is discharged out of the box step by step, and the humidity in the dehumidification box is reduced step by step; when the humidity in the box reaches a set lower limit, the controller 5 closes the dehumidification dryer 6 to heat, and simultaneously closes the micro pipeline fan 8, the valve port I and the valve port III to connect the valve port I; the air inside and outside the dehumidifying box is isolated and then communicated with the box to be dried, and the dehumidifying dryer 6 starts to absorb the moisture in the air in the communicated space in the whole box body 12, so that the aim of reducing the relative humidity in the box to be dried is achieved; the operation is repeated in cycles.

The functions and the flow are as follows:

in daily time, wet air enters from the first valve hole and enters the inner space of the drying and dehumidifying box 1 through the second valve hole of the two-position three-way cut-off type electromagnetic valve, and moisture in the air is adsorbed by the dehumidifying dryer 6;

when the temperature and humidity sensor 11 detects that the humidity of the inner chamber of the dehumidifier is greater than or equal to 60%, the temperature and humidity controller 5 sends an instruction signal to the controller 5, and the controller 5 controls the dehumidification dryer 6, the two-position three-way cut-off electromagnetic valve, the micro pipeline fan 8 and the two-position two-way direct-acting electromagnetic valve to be electrified simultaneously and successively; at the moment, the first valve port, namely the humid air inlet 3 is in a closed state, and the first valve port, namely the fresh air inlet 2 is opened; a valve hole III, namely a humid air outlet 4 is also opened due to the electrification of a two-position three-way cut-off type electromagnetic valve; the micro pipeline fan 8 is electrified to start working, so that high-speed flowing new air enters the inner space of the drying and dehumidifying box 1 and enters the inner chamber of the dehumidifying drier 6 to be mixed with high-temperature moisture evaporated after being heated by the dehumidifying drier 6 to be blown out of the drying and dehumidifying box 1 through the valve hole three, and the dehumidifying process is finished.

After the dehumidification process lasts for a period of time, when the humidity in the box is reduced and the temperature and humidity sensor 11 detects that the humidity is less than or equal to 25%, the device can automatically stop all electric appliances to work, the dehumidification completes one cycle, the two-position three-way stop type electromagnetic valve controls the opening of the valve hole, then the dehumidification step is carried out, and the next cycle process is continued.

In the above, the dehumidification control can be realized by manually setting the parameters of the temperature and humidity controller 5, the upper limit parameter is the start of dehumidification air draft, and the lower limit parameter is the stop of the operation of each electric appliance. The parameters are generally set to be an upper limit parameter of-60-65% and a lower limit parameter of-25-40%; and can be set according to actual conditions.

In summary, the device is suitable for the types requiring dehumidification and drying: the drying agent is used for household, electronic products, clothes, industrial products and the like, and objects needing drying do not need to be burnt, exploded or corroded in a closed space. The device is an independent work circulation device, when in installation, only a humid air inlet is communicated with a dried facility, and the dried facility is generally an electric box to complete moisture absorption, heating drying and fresh air circulation regeneration; the device has the advantages of automatic control of the whole work, compact design, reasonable layout, portability, small size, small occupied space and convenient installation and use.

The above detailed description is made on the intermittent drying and dehumidifying device provided by the embodiment of the present invention, and the specific examples are applied herein to explain the principle and the implementation of the present invention, and the description of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
