[0035] A dehumidifier is a machine that converts humid air into dry air for discharge. Depending on the application scenario, dehumidifiers can be divided into industrial and residential dehumidifiers. Existing dehumidifiers typically pass air through an evaporator and condenser, then through a ventilator, with air discharged from the top of the unit, completing the dehumidification cycle.

[0036] The dehumidifier structure in the related art has the technical problem that the dew point temperature is single and cannot be adjusted.

[0037] Please refer to Figure 1-Figure 3This embodiment provides a dehumidifier structure, which can effectively improve the technical problems mentioned above, can achieve dual dew point temperature dehumidification, and at the same time achieve the purpose of stable and adjustable dew point, which is more convenient to use.

[0038] The dehumidifier structure includes a compressor 120, a condenser 10, a liquid reservoir 100, a first evaporator 20, a first electronic expansion valve 40, a second evaporator 30 and a second electronic expansion valve 50. The outlet pipe of the compressor 120 is connected to the inlet pipe of the condenser 10. The compressor 120 is used to compress and pressurize the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas to provide power for the refrigeration system. After the high-temperature and high-pressure gas refrigerant enters the pipe of the condenser 10, its temperature is dissipated through the pipe of the condenser 10, and the heat of the high-temperature and high-pressure gas is transferred to the air, which is used to cool the refrigerant from the high-temperature and high-pressure gas to a medium-temperature and high-pressure liquid, thereby achieving the refrigerant. Heat dissipation; the outlet pipe of the liquid reservoir 100 is connected to the condenser 10, and the liquid reservoir 100 is used to store the medium-temperature and high-pressure liquid refrigerant output from the condenser 10, and can provide stable refrigerant for the first electronic expansion valve 40 and the second electronic expansion valve 50; the first evaporator 20 is connected to the condenser 10, the first electronic expansion valve 40 is connected to the inlet pipe of the first evaporator 20, the second evaporator 30 is connected to the condenser 10, and the second electronic expansion valve 50 is connected to the inlet pipe of the second evaporator 30; wherein, the first electronic expansion valve 40 and the second electronic expansion valve 50 are used to adjust the dew point temperature of the first evaporator 20 and the second evaporator 30 respectively.

[0039] Specifically, a condensing fan 11 is installed on the condenser 10, and the condensing fan 11 can accelerate the heat exchange between the heat inside the condenser 10 and the air, thereby quickly cooling the refrigerant from high-temperature and high-pressure gas to medium-temperature and high-pressure liquid.

[0040] In this embodiment, a tee 60 is provided on the outlet pipe of the condenser 10. The tee 60 is used to divide the outlet pipe of the condenser 10 into a first pipe and a second pipe. The first pipe is connected to the first evaporator 20, and the second pipe is connected to the second evaporator 30. Specifically, the tee 60 is provided on the outlet pipe of the liquid reservoir 100, and the tee 60 divides the pipe into two, which are respectively connected to the inlet positions of the first electronic expansion valve 40 and the second electronic expansion valve 50.

[0041] It should be noted that the first electronic expansion valve 40 and the second electronic expansion valve 50 are used to reduce the pressure of medium-temperature and high-pressure refrigerant to a low-temperature and low-pressure gas-liquid mixed refrigerant, thereby providing the first evaporator 20 and the second evaporator 30 with a low-temperature and low-pressure gas-liquid mixed refrigerant. The first electronic expansion valve 40 and the second electronic expansion valve 50 both have built-in stepper motors, which are connected to an external control module. The stepper motors are driven to rotate by the external control module, so that the stepper motors adjust the opening and closing degrees of the first electronic expansion valve 40 and the second electronic expansion valve 50, thereby adjusting the refrigerant flow and pressure entering the first evaporator 20 and the second evaporator 30 respectively, thereby realizing the regulation of the dew point temperature of the first evaporator 20 and the second evaporator 30.

[0042] In this embodiment, the adjustment range of the stepper motors of the first electronic expansion valve 40 and the second electronic expansion valve 50 are both 0-480 steps.

[0043] Specifically, after the refrigerant enters the first evaporator 20 and the second evaporator 30, it vaporizes into a low-temperature, low-pressure gaseous refrigerant. When the low-temperature, low-pressure gaseous refrigerant flows inside the first evaporator 20 and the second evaporator 30, it can absorb heat from the air to achieve cooling.

[0044] It should be noted that the outlet pipe of the first evaporator 20 and the outlet pipe of the second evaporator 30 are connected to the return air pipe of the compressor 120 at the same time, and a one-way valve 110 is provided on the outlet pipe of the first evaporator 20 to control the flow direction of the refrigerant and prevent the refrigerant flowing out of the outlet pipe of the second evaporator 30 from flowing into the first evaporator 20, affecting the temperature control of the first evaporator 20.

[0045] Furthermore, in order to speed up the heat exchange between the heat in the second evaporator 30 and the air, an evaporation fan 140 is provided on the second evaporator 30 .

[0046] It can be understood that the heat in the air is taken away by the refrigerant in the first evaporator 20 and the second evaporator 30, thereby reducing the outlet air temperature. When the outlet air relative humidity reaches 100%, the temperature at this time is the dew point temperature. At this time, the gaseous water in the air above the first evaporator 20 and the second evaporator 30 will be liquefied into liquid water. In order to collect the liquid water in the first evaporator 20 and the second evaporator 30, a water receiving tray 130 is provided at the bottom of the first evaporator 20 and the second evaporator 30.

[0047] It should also be noted that the dehumidifier structure also includes an outer shell 70, a first partition 80 and a second partition 90. The first partition 80 is arranged in the outer shell 70. The first partition 80 is used to isolate the internal space of the outer shell 70 from the first dehumidification air duct 101 and the second dehumidification air duct 102. The first evaporator 20 is installed in the first dehumidification air duct 101, and the second evaporator 30 is installed in the second dehumidification air duct 102. The first electronic expansion valve 40 and the second electronic expansion valve 50 are both installed on the first partition 80. The second partition 90 and the first partition 80 are arranged parallel to each other, and the second partition 90 is arranged in the outer shell 70. The second partition 90 is used to isolate the internal space of the outer shell 70 from the condensation air duct 103. The condensation air duct 103 and the first dehumidification air duct 101 are arranged adjacent to each other, and the condenser 10 is installed in the condensation air duct 103.

[0048] Specifically, the outer shell 70 is a vertical square structure, the first partition 80 and the second partition 90 are both arranged horizontally, the first partition 80 and the bottom surface of the outer shell 70 are parallel, the second partition 90 is located above the first partition 80, the bottom surface of the first partition 80 and the bottom surface and side wall of the outer shell 70 jointly define the first dehumidification air duct 101, the top surface of the first partition 80, the bottom surface of the second partition 90 and the side wall of the outer shell 70 jointly define the second dehumidification air duct 102, and the top surface of the second partition 90, the side wall and top surface of the outer shell 70 jointly define the condensation air duct 103. The condenser 10 is installed in the condensing air duct 103, the first evaporator 20 is installed in the first dehumidification air duct 101, the second evaporator 30, the compressor 120 and the liquid storage tank 100 are all installed in the second dehumidification air duct 102. By forming a stacked structure through the condensing air duct 103, the first dehumidification air duct 101 and the second dehumidification air duct 102, the floor space of the dehumidifier can be effectively reduced.

[0049] In this embodiment, the air inlets and outlets of the first dehumidification duct 101 and the second dehumidification duct 102 are both disposed on the sidewalls of the housing 70. The air flow direction of the first dehumidification duct 101 is opposite to that of the second dehumidification duct 102. Specifically, the air inlets and outlets of the first dehumidification duct 101 and the second dehumidification duct 102 are disposed opposite to each other, thereby achieving air convection and thereby cooling and dehumidifying the air.

[0050] Specifically, an exhaust port 104 is provided at the top of the shell 70, and the exhaust port 104 is connected to the condensation air duct 103. An exhaust flange is installed at the position of the exhaust port 104, and the exhaust pipe is installed at the exhaust port 104 through the exhaust flange. The gas in the shell 70 is discharged through the exhaust pipe.

[0051] Specifically, the condenser 10 is fixed to the top surface of the housing 70 , and the condensing fan 11 of the condenser 10 can accelerate the heat exchange between the condenser 10 and the air, thereby transferring the heat in the condenser 10 to the air.

[0052] It should also be explained that a fin fixing plate 150 is provided at the bottom of the outer shell 70, and the first evaporator 20 is fixed on the fin fixing plate 150 to achieve installation. The first evaporator 20 is used to cool and dehumidify the wind flowing through the first dehumidification air duct 101. A wind valve 160 is provided at the front end of the first evaporator 20. The wind valve 160 is rotated by the wind valve actuator 170 to rotate the drive shaft hinge angle, thereby used to adjust the ventilation cross-sectional area of ​​the air duct. The inlet of the wind valve 160 is fixed with an air outlet reducer 180, and the top surface of the second partition 90 is also provided with a fin fixing plate 150. The second evaporator 30 is fixed on the fin fixing plate 150.

[0053] In this embodiment, the outer shell 70 includes a column 71 and a plurality of wind plates 72. The column 71 and the plurality of wind plates 72 together form a vertical square structure. The evaporating fan 140 of the second evaporator 30 is installed on the wind plate 72 at the air outlet of the second dehumidification air duct 102, and is used to increase the convection speed of the air in the second dehumidification air duct 102. The speed of the evaporating fan 140 is adjustable, thereby realizing the control of the dehumidification amount and dew point temperature.

[0054] In this embodiment, thermal insulation is provided on both sides of the first partition 80 and the second partition 90. The thermal insulation can isolate the first dehumidification air duct 101 and the second dehumidification air duct 102, preventing heat exchange between the first evaporator 20 and the second evaporator 30, thereby eliminating heat conduction.

[0055] It can be understood that all the air plates 72 of the housing 70 are provided with thermal insulation cotton to prevent heat exchange with the outside world.

[0056] Specifically, in order to filter out dust and large solid particles in the first dehumidification duct 101, a filter 190 is provided in the first dehumidification duct 101. The filter 190 can be pulled out and arranged at the air inlet of the first dehumidification duct 101, and the filter 190 covers the side of the air outlet reducer 180 away from the air valve 160.

[0057] In addition, the dehumidifier structure further includes an electrical box 200 , which is installed in the condensing air duct 103 .

[0058] In summary, the present invention provides a dehumidifier structure comprising a condenser 10, a first evaporator 20, a first electronic expansion valve 40, a second evaporator 30, and a second electronic expansion valve 50. The first evaporator 20 is connected to the condenser 10, the first electronic expansion valve 40 is connected to the inlet pipe of the first evaporator 20, the second evaporator 30 is in communication with the condenser 10, and the second electronic expansion valve 50 is connected to the inlet pipe of the second evaporator 30.
