When the temperature in the cabinet body rises to a set value, the bimetallic strip 14 deforms, the pull rope 26 is pulled to pull the inner air duct barrier plate 25 to slide downwards, the first elastic piece 26 is compressed, the inner air inlet 131 is in an open state, at the moment, air enters the inner air inlet 131 from the upper air inlet 11, the reason that the air inlet is changed into the upper air inlet is that the humidity of the ground surface is the largest, the humidity is smaller as the air enters from the upper portion, and the humidity of the entering air is reduced as the humidity of the air is smaller as the humidity is larger.

It can press touch control switch 34 after bimetallic strip 14 warp on, thereby make compressor 33 circular telegram, compressor 33 rotates, condensate agent compression with in the cooling tube 32 enters into condenser pipe 31, thereby make the temperature reduction on the condenser pipe 31, the air that makes inside air intake 131 get into passes through condenser pipe 31 earlier, make the steam condensation in the air on condenser pipe 31, thereby reduce the humidity that gets into the air, and compressor 33 is connected with humidity varistor components and parts 132, humidity varistor components and parts 132 are according to the size of the change resistance of humidity, thereby the speed of control compressor 33 rotational speed, thereby change the temperature of condenser pipe 31, the steam condensation efficiency of air is passed through in the control.

The condensed water from the condensation pipe 31 enters the water storage box 18 through the condensed water collection box 17 for storage.

After dust or water vapor adheres to the surface of the observation window 41, light emitted from the emitter 61 is difficult to pass through the observation window 41, so that the receiver 62 cannot receive a signal, and thus an instruction is given to the intelligent lock 7, the motor 551 is powered on, the motor 551 is started to drive the flat gear 552 to rotate, the hanging and sweeping device 51 slides downwards along the guide rail rack 53, the right guide block 513 on the hanging and sweeping device 51 drives the magnetic piston 542 to slide together in the downwards sliding process, so that the air pressure person is pressed into the water storage box 18, the air pressure in the water storage box 18 is increased, the sliding plug 19 is pushed upwards to block the water inlet 181, a closed space is formed in the water storage box 18, the magnetic piston 542 continuously slides downwards, the air pressure in the water storage box 18 is continuously increased, the water stored in the water storage box is pressed out from the bottom of the magnetic piston 542 to the nozzle 521 on the water spray pipe 52, and the water is sprayed on the observation window 41, when the hanging and sweeping device 51 slides downwards, water is sprayed firstly, then the observation window 41 is swept, when the hanging and sweeping device 51 runs to the lowest end, the motor 551 rotates reversely, so that the hanging and sweeping device 51 slides upwards along the guide rail rack 53, the right guide block 513 on the hanging and sweeping device 51 drives the magnetic piston 542 to slide upwards together in the process of sliding upwards, air in the water storage box 18 is pumped into the inflator 541, the air pressure in the water storage box 18 is reduced, the sliding plug 19 slides downwards, so that the external air can enter the water storage box 18 through the water inlet hole 181, as the receiver 62 is fixedly arranged in the cabinet door 4, when the hanging and sweeping device 51 drives the transmitter 61 to move, the receiver 62 cannot receive signals all the time, when the hanging and sweeping device 51 slides upwards and downwards once and returns to the starting position of the upper part, the observation window is wiped clean at this time, so the receiver 62 can receive signals, therefore, the intelligent lock 7 is instructed to stop electrifying the motor 551, and the cleaning can be automatically carried out when dust or water vapor is attached to the observation window 41.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
