[0028] This utility model relates to a fresh air dehumidifier, specifically including a main unit installed indoors, a fresh air inlet 20 installed outdoors, and an exhaust outlet 21. The internal structure of the main unit is as follows: Figures 1-4 As shown, the main components include a housing 1, a fan bracket 2 installed inside the housing 1, a fan 3 fixed to the fan bracket 2, a condenser 4 installed on one side of the fan 3, an evaporator 5 installed on one side of the condenser 4, a humidity sensor 6, a temperature sensor 7, a filter screen 8, a baffle plate 9, a water collection tank 10, a drain pipe 11, support feet 12, and an anti-slip pad 13. A control console 16 is installed on the outside of the main unit, including a display screen 17, operation buttons 18, and a wireless communication module 19. A fresh air inlet 20 and an exhaust outlet 21 are connected to the main unit via fresh air ducts and exhaust ducts, respectively. Valves 22 are also installed at the fresh air inlet 20 and the exhaust outlet 21, which are intelligently controlled by a controller (not shown in the figure). The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0029] First, the main unit's casing 1 is the foundational structure of the entire fresh air dehumidifier. Its material can be high-strength engineering plastics or metal, offering excellent corrosion resistance and weather resistance. The internal space of casing 1 is rationally designed to accommodate all components of the main unit and ensure their normal operation. The fan bracket 2 includes a horizontally positioned base plate, vertically positioned columns on the base plate, and a horizontally positioned top plate on top of the columns. The fan 3 is fixed to the top plate. This design ensures stable operation of the fan 3, reducing vibration and noise. The function of the fan 3 is to introduce fresh outdoor air into the main unit through the fresh air duct, while simultaneously exhausting humid indoor air through the exhaust duct. The condenser 4 and evaporator 5 are respectively located on both sides of the fan 3. The condenser 4 condenses the moisture in the air into liquid water, while the evaporator 5 heats the condensed air, maintaining its temperature within a suitable range.
[0030] Humidity sensor 6 and temperature sensor 7 are installed inside housing 1 to monitor indoor air humidity and temperature in real time, respectively, and transmit this data to the controller. Based on the monitoring data from humidity sensor 6 and temperature sensor 7, the controller intelligently adjusts the operating status of fan 3, condenser 4, and evaporator 5 to achieve optimal dehumidification and reduce energy consumption. For example, when indoor humidity is high, the controller increases the operating power of fan 3 and condenser 4 to improve dehumidification efficiency; when indoor humidity is low, the controller reduces the operating power of fan 3 and condenser 4 to reduce energy consumption. Simultaneously, temperature sensor 7 monitors indoor temperature to prevent evaporator 5 from overheating and affecting indoor air comfort.
[0031] The fresh air inlet 20 is connected to the main unit's casing 1 via a fresh air duct. The fresh air duct can be made of flexible or rigid PVC material, offering good airtightness and durability. A valve 22 is installed at the fresh air inlet 20, controlled by a controller. This valve can open or close as needed to prevent direct entry of outdoor air and ensure fresh air quality. For example, in cases of poor air quality or high outdoor humidity, the controller will close valve 22 to reduce the chance of outdoor air entering the room. The exhaust outlet 21 is connected to the main unit via an exhaust duct made of the same material as the fresh air duct. A valve 22 is also installed at the exhaust outlet 21, controlled by the controller, to expel humid indoor air. By intelligently controlling the valves 22 at the fresh air inlet 20 and exhaust outlet 21, this invention maintains indoor air circulation while preventing the direct entry of polluted outdoor air.
[0032] The main unit's casing 1 also contains a filter 8, which is installed at the connection between the fresh air intake 20 and the main unit. Figure 1 As shown. Filter 8 can be made of high-efficiency filter materials, such as HEPA filters, which can effectively filter harmful substances such as dust, pollen, and bacteria from outdoor air, ensuring the quality of fresh air entering the room. Filter 8 can be fixed inside the housing 1 with clips, making it easy for users to clean or replace it regularly to maintain its filtering effect. In addition, sealing rings can be provided on both sides of filter 8 to enhance airtightness and prevent unfiltered air from directly entering the room.
[0033] The baffle plate 9 is positioned between the condenser 4 and the evaporator 5, such as... Figure 3As shown. The guide plate 9 has an arc-shaped structure, with its two ends fixed to the inner wall of the housing 1. The design of the guide plate 9 effectively guides condensate to flow quickly into the water collection tank 10, preventing condensate from accumulating inside the main unit and causing malfunctions such as corrosion and short circuits. The water collection tank 10 is located at the bottom of the guide plate 9 and can be made of stainless steel or corrosion-resistant plastic. Its capacity is reasonably designed to hold a certain amount of condensate. The water collection tank 10 is connected to the outside of the main unit through a drain pipe 11, one end of which extends outside the main unit to drain the condensate. The drain pipe 11 can be made of PVC or metal pipe, which has good corrosion resistance and structural strength. The design of the water collection tank 10 and the drain pipe 11 ensures the dryness inside the main unit and improves the dehumidification effect.
[0034] The bottom of the main unit's casing 1 is equipped with support feet 12, such as... Figure 2 As shown. There can be four support feet 12, evenly distributed at the bottom of the housing 1, ensuring the stability and balance of the main unit. The bottom of each support foot 12 is equipped with an anti-slip pad 13, which can be made of rubber or silicone, providing good anti-slip performance and shock absorption to prevent displacement or vibration of the main unit during use. Furthermore, the height of the support feet 12 is adjustable, allowing users to adjust them according to the actual installation environment to ensure the levelness and stability of the main unit.
[0035] Ventilation holes 14 are provided on both sides of the casing 1, such as... Figure 4 As shown. The number and placement of the ventilation holes 14 are rationally designed to effectively dissipate heat and prevent the internal temperature of the host from becoming too high. A dust filter 15 is provided on the outside of the ventilation holes 14. The dust filter 15 can be made of stainless steel or nylon mesh, which has good air permeability and dustproof effect, ensuring the cleanliness of the inside of the host. The design of the ventilation holes 14 and the dust filter 15 not only improves the heat dissipation efficiency of the host, but also prevents dust from entering the host, extending the service life of the host.
[0036] Console 16 is located on the outside of the host, such as... Figure 1 As shown in the diagram, the control panel 16 is equipped with a display screen 17 and operation buttons 18. The display screen 17 is connected to the controller and can display the indoor humidity and temperature in real time, as well as the operating status of the main unit. The operation buttons 18 are connected to the controller, allowing users to manually adjust functions such as adjusting dehumidification intensity, turning the unit on and off, and setting timers. The control panel 16 also includes a wireless communication module 19, which is connected to the controller for communication with external smart devices. For example, users can remotely control the operating status of the main unit using smartphones or tablets, improving ease of use. The wireless communication module 19 can employ communication technologies such as Wi-Fi, Bluetooth, or 4G / 5G to achieve remote monitoring and control.
[0037] The following describes the specific operating principle and process of this novel fresh air dehumidifier. First, fresh outdoor air enters the main unit through the fresh air inlet 20, passes through the filter 8, and then enters the housing 1. The filter 8 effectively removes harmful substances such as dust, pollen, and bacteria from the air, ensuring the quality of the air entering the room. Next, the air entering the main unit is processed by the condenser 4, which condenses the moisture in the air into liquid water. The liquid water flows onto the guide plate 9. The arc-shaped structure of the guide plate 9 effectively guides the condensate to quickly converge into the water collection tank 10. The water collection tank 10 discharges the condensate from the main unit through the drain pipe 11, keeping the inside of the main unit dry.
[0038] After being dehumidified by condenser 4, the air continues to be heated by evaporator 5. Evaporator 5 raises the air temperature to a suitable range, preventing the air from entering the room at an excessively low temperature, which would affect indoor comfort. The heating power of evaporator 5 can be intelligently adjusted according to indoor temperature and humidity, achieving precise control. For example, when the indoor temperature is low, evaporator 5 increases its heating power to raise the air temperature; when the indoor temperature is high, evaporator 5 reduces its heating power to prevent the indoor temperature from becoming too high.
[0039] Based on monitoring data from humidity sensor 6 and temperature sensor 7, the controller intelligently adjusts the operating status of fan 3, condenser 4, and evaporator 5. Fan 3 has multiple speed settings, which control the amount of fresh air entering the room. The operating power of condenser 4 and evaporator 5 can also be dynamically adjusted according to indoor humidity and temperature to ensure a balance between dehumidification effect and energy consumption. For example, when indoor humidity is high, the controller increases the speed of fan 3 and the cooling power of condenser 4 to improve dehumidification efficiency; when indoor humidity is low, the controller reduces the speed of fan 3 and the cooling power of condenser 4 to reduce energy consumption. Temperature sensor 7 monitors indoor temperature, and the controller adjusts the heating power of evaporator 5 accordingly to maintain the indoor air temperature within a suitable range.
[0040] The valves 22 at the fresh air inlet 20 and the exhaust outlet 21 are intelligently controlled by a controller. When the indoor air quality is good and the humidity is moderate, the controller opens the valve 22 at the fresh air inlet 20 and closes the valve 22 at the exhaust outlet 21, allowing fresh outdoor air to enter the room. When the indoor air quality is poor or the humidity is high, the controller opens the valve 22 at the exhaust outlet 21 and closes the valve 22 at the fresh air inlet 20, expelling the humid indoor air through the exhaust duct. By intelligently controlling the valves 22, this invention effectively maintains indoor air circulation while preventing the direct entry of undesirable outdoor air, thus improving the quality of fresh air.
[0041] Users can manually adjust the dehumidifier using the operation buttons 18 on the control panel 16, such as adjusting the dehumidification intensity, turning it on and off, and setting a timer. The display screen 17 shows the indoor humidity and temperature in real time, as well as the operating status of the main unit, helping users understand the current indoor environment. Furthermore, the wireless communication module 19 can communicate with external smart devices, allowing users to remotely control the main unit's operation. For example, users can remotely turn the dehumidifier on or off, set the dehumidification intensity and timer, and ensure that the indoor humidity and temperature are within a suitable range when they return home while traveling or away from home.
[0042] The specific installation process of this novel fresh air dehumidifier is as follows: First, place the main unit's casing 1 in a suitable indoor location, and adjust the height of the support feet 12 to ensure the main unit's levelness and stability. Next, connect one end of the fresh air duct to the fresh air inlet 20 and the other end to the outdoor fresh air source. Similarly, connect one end of the exhaust duct to the exhaust outlet 21 and the other end to the indoor exhaust vent. During installation, pay attention to the airtightness and secure fixing of the ducts to avoid air leakage and loosening. Finally, install the filter 8 at the connection between the fresh air inlet 20 and the main unit, ensuring a good seal on both sides of the filter 8. After installation, the user can start the fresh air dehumidifier by operating button 18 or through an application on a smart device, and adjust and control it according to the needs of the indoor environment.
[0043] The specific application scenario of this novel fresh air dehumidifier is as follows: Assume a user lives in a humid southern region where indoor humidity is often above 80%, which is detrimental to human health and the preservation of belongings. The user can install this novel fresh air dehumidifier and set the appropriate range for indoor humidity and temperature via the control panel 16, for example, setting the indoor humidity between 40% and 60% and the temperature between 25 and 30 degrees Celsius. After the main unit starts, fresh outdoor air enters the main unit through the fresh air inlet 20, passes through the filter 8, and then enters the housing 1. The condenser 4 condenses the moisture in the air into liquid water, which flows through the guide plate 9 into the water collection tank 10 and is discharged from the main unit through the drain pipe 11. The air dehumidified by the condenser 4 is then heated by the evaporator 5 to increase the air temperature, ensuring a comfortable indoor temperature. Simultaneously, the humidity sensor 6 and temperature sensor 7 monitor the indoor environment in real time, and the controller intelligently adjusts the operating status of the fan 3, condenser 4, and evaporator 5 based on the monitoring data to ensure a balance between dehumidification effect and energy consumption. For example, when the indoor humidity is high, the controller will increase the speed of fan 3 and the cooling power of condenser 4 to improve dehumidification efficiency; when the indoor humidity is low, the controller will reduce the speed of fan 3 and the cooling power of condenser 4 to reduce energy consumption. Users can also remotely control the operation status of the fresh air dehumidifier using smart devices via wireless communication module 19 to achieve real-time monitoring and intelligent adjustment.
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
