DETAILED DESCRIPTION

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a dehumidifier with low-temperature anti-freezing function, including a dehumidifier shell 1. An air intake grille 7 is fixedly installed on the rear end of the dehumidifier shell 1. Two temperature sensors 12 are symmetrically fixedly installed on the inner bottom end of the air intake grille 7 to monitor the temperature of the incoming air in real time. A dustproof net 13 is fixedly installed on the inner side of the end of the air intake grille 7 near the dehumidifier shell 1 to filter dust and other impurities in the air. A guide frame 14 is fixedly installed inside the dehumidifier shell 1 at the position of the air intake grille 7. A reflective film 15 is attached to the inner top of the guide frame 14. A heater 16 is fixedly installed on the reflective end face of the bottom end of the reflective film 15 at the inner top of the guide frame 14. The heat emitted by the heater 16 can be reflected to the inner side of the guide frame 14 through the reflection of the reflective film 15 to improve the heating efficiency.

[0023] An exhaust grille 3 is fixedly installed on the inner side of the top center of the dehumidifier housing 1. A controller 4 is fixedly installed inside the top of the dehumidifier housing 1. A display screen 2 is fixedly installed on the upper front of the dehumidifier housing 1. The controller 4 transmits operating information to the display screen 2 for display. Users can view the equipment's operating status through the display screen 2. A transparent viewing window 6 is fixedly installed on the lower front of the dehumidifier housing 1. The transparent viewing window 6 allows users to easily observe the water level inside the water collection tank 8. The dehumidifier body 9 is fixedly installed inside the dehumidifier housing 1. Exhaust fans 10 are evenly fixedly installed at the top output end of the dehumidifier body 9. An exhaust pipe 11 is fixedly installed above the output end of the dehumidifier body 9. Universal wheels 5 are evenly fixedly installed at the bottom of the dehumidifier housing 1. The universal wheels 5 allow for flexible movement of the dehumidifier housing 1 for convenient use. A water collection tank 8 is movably inserted into the lower rear of the dehumidifier housing 1. The water collection tank 8 is made of transparent material. The transparent viewing window 6 is located directly in front of the water collection tank 8, allowing for easy observation of the water level inside the water collection tank 8 for handling condensate.

[0024] The controller 4 is electrically connected to the display screen 2, the dehumidifier body 9, the exhaust fan 10, the temperature sensor 12, and the heater 16. By setting the control program through the controller 4, the corresponding heating power can be activated to heat the air in accordance with the ambient temperature.

[0025] The air guide frame 14 is designed in an M shape. The end of the air guide frame 14 away from the air intake grille 7 is fixedly installed at the input end of the dehumidifier body 9. External air enters through the end near the air intake grille 7, moves upward and is heated by the heater 16, and then moves to the end near the dehumidifier body 9 to enter the interior of the dehumidifier body 9. The M-shaped design can guide the air to the position of the heater 16 for easy heating of the air. The top of the exhaust pipe 11 is fixedly installed inside the top of the dehumidifier housing 1, and the top of the exhaust pipe 11 is located directly below the air outlet grille 3.

[0026] Working Principle: During use, the control program is first set via controller 4. Then, the dehumidifier housing 1 is pushed to the desired dehumidification position by external force. Next, controller 4 controls the dehumidifier body 9 and exhaust fan 10 to start dehumidification. The exhaust fan 10 draws air out of the dehumidifier body 9 and discharges it through exhaust pipe 11. The reduced air pressure inside the dehumidifier body 9 draws in air from outside the dehumidifier housing 1 through the guide frame 14. After dehumidifying the air, the dehumidifier body 9 discharges it through exhaust pipe 11. The outside air is filtered through dust filter 13 to prevent dust and debris from entering and damaging the dehumidifier body 9. Condensed water drips into the water collection tank 8 through the drain pipe. The water level inside the water collection tank 8 can be observed in real time through the transparent viewing window 6. The temperature sensor 12 monitors the temperature of the air entering the dehumidifier housing 1 in real time and transmits it to the controller 4. When the temperature information received by the controller 4 is lower than the preset value, the controller 4 controls the heater 16 to start. The heater 16 heats the incoming air. The controller 4 can set different heating power for the air heater 16 for different temperature zones, so as to achieve the required temperature range for the air delivered to the dehumidifier body 9 and avoid the impact of low temperature on dehumidification.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
