Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] like Figure 1-3 As shown, the utility model provides a novel high-efficiency low-temperature resistant dehumidifier, comprising a dehumidifier casing 1, a partition 2 is fixedly arranged inside the dehumidifier casing 1, and a defrosting assembly is arranged at the bottom inside the dehumidifier casing 1.

[0030] Specifically, the defrosting component includes a micro fan 3 and a heating box 6. The micro fan 3 and the heating box 6 are fixedly arranged at the bottom of the dehumidifier housing 1. The micro fan 3 is located on the left side of the heating box 6. The suction end of the micro fan 3 is fixedly provided with a suction pipe 4. The other end of the suction pipe 4 is opened on the left side of the upper end surface of the partition 2. The outlet end of the micro fan 3 is fixedly provided with a connecting pipe 5. The other end of the connecting pipe 5 is fixedly arranged at the air inlet of the heating box 6. The outlet of the heating box 6 is fixedly provided with an outlet pipe 7. The other end of the outlet pipe 7 is opened on the right side of the upper end surface of the partition 2. The advantage is that when the micro fan 3 is started, the micro fan 3 can transport the cold air at the upper end of the partition 2 to the inside of the heating box 6 through the suction pipe 4 and the connecting pipe 5. The heating box 6 heats the cold air and transports it back to the upper end of the partition 2 through the outlet pipe 7, thereby forming a cycle, so that it can play a defrosting role, which is convenient for the dehumidifier to be used in cold areas.

[0031] Specifically, a solenoid valve 8 is installed inside the air suction pipe 4 and the air outlet pipe 7. The advantage is that when defrosting is needed, the solenoid valve 8 is opened to start the micro fan 3 and the heating box 6 for defrosting, and when defrosting is not needed, the air suction pipe 4 and the air outlet pipe 7 can be closed.

[0032] Specifically, a water collecting box 15 is fixedly arranged on the left side of the upper end surface of the partition 2, a drainage hole 16 is provided on the back of the water collecting box 15, an evaporator 10 is installed at the bottom of the water collecting box 15, a condenser 14 is sleeved on the outside of the evaporator 10, a compressor 11 is installed at the top of the dehumidifier housing 1, an expansion valve 13 and a condenser 12 are installed on the upper end surface of the partition 2, the expansion valve 13 is located between the water collecting box 15 and the condenser 12, and a connecting pipe is arranged between the evaporator 10 and the compressor 11, the compressor 11 and the condenser 12, the condenser 12 and the expansion valve 13, and the expansion valve 13 and the evaporator 10. The advantage is that the arrangement of the evaporator 10, the compressor 11, the condenser 12, the expansion valve 13, and the condenser 14 can play a role in dehumidification.

[0033] Specifically, a temperature and humidity sensor 9 is installed on the left side of the top of the dehumidifier housing 1, and installation slots 17 are provided on both sides of the dehumidifier housing 1. A ventilation component is provided inside the installation slot 17. The advantage is that the temperature and humidity sensor 9 can monitor the temperature and humidity.

[0034] Embodiment 2:

[0035] like Figure 1-4 As shown, as an improvement to the previous embodiment. Specifically, the ventilation assembly includes a filter plate 18 and a fan 19. The filter plates 18 are installed on both sides of the inside of the installation slot 17, and the fan 19 is installed between the filter plates 18 on both sides. The advantage is that the arrangement of the filter plate 18 facilitates the installation of the fan 19, and the arrangement of the fan 19 can play a ventilation role.

[0036] Specifically, a protective shell 20 is fixedly arranged on the back of the dehumidifier housing 1, a water collecting box 21 is arranged inside the protective shell 20, a drain pipe 22 is opened on the upper end surface of the protective shell 20, and the other end of the drain pipe 22 is connected to the drain hole 16, and a control panel 23 is installed on the front of the dehumidifier housing 1. The advantage is that the water droplets condensed in the condenser tube 14 can drip downward and fall into the water collecting box 1 15, and then the water droplets can flow into the inside of the water collecting box 21 through the drain hole 16 and the drain pipe 22, so that the water generated by the dehumidifier can be collected.

[0037] When the dehumidifier is used in a cold area and frost occurs, the personnel open the solenoid valve 8 through the control panel 23 to start the micro fan 3 and the heating box 6. The micro fan 3 can transport the cold air at the upper end of the partition 2 to the inside of the heating box 6 through the air suction pipe 4 and the connecting pipe 5. The heating box 6 heats the cold air and transports it back to the upper end of the partition 2 through the air outlet pipe 7, thereby forming a cycle, which can play a defrosting role. After the defrosting is completed, the solenoid valve 8 can be closed, and then the dehumidifier can be started. The low-pressure gas in the connecting pipe becomes high-pressure gas under the action of the compressor 11, and then the condenser 1 2 becomes a high-pressure liquid, becomes a low-pressure liquid under the action of the expansion valve 13, and becomes a low-pressure gas under the action of the evaporator 10, thus forming a cycle. When the low-pressure liquid becomes a low-pressure gas, the evaporator 10 absorbs heat, and the left fan 19 transports the external humid gas to the right. The moisture inside the humid gas is adsorbed on the condenser 14 under the action of the evaporator 10, and then the water droplets drip down into the water collecting box 1 15, and finally enter the interior of the water collecting box 2 21 through the drainage hole 16 and the drainage pipe 22 to complete the collection. The dehumidified gas is discharged into the room under the action of the fan 19 on the right.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
