Description

Constant temperature and humidity plasma air sterilizer Technical Field

[0001] This utility model relates to the field of disinfection equipment, and in particular to a constant temperature and humidity plasma air disinfection machine. Background Technology

[0002] For indoor environments with high cleanliness requirements, air purifiers are needed to filter and disinfect the air. However, existing air purifiers cannot regulate the temperature and humidity of the air during the filtration and disinfection process, and may even cause the air to become increasingly dry, making them unsuitable for direct application in indoor environments with constant temperature and humidity requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a constant temperature and humidity plasma air sterilizer that can adjust temperature and humidity.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] A constant temperature and humidity plasma air sterilizer includes a housing with an air inlet at the lower end and an air outlet at the upper end. Inside the housing, between the air inlet and outlet, arranged sequentially from top to bottom, are a first filter, a constant temperature and humidity module, a plasma generator, and a second filter. The constant temperature and humidity module includes a water collection tank, an evaporator, and a fan. The water collection tank is located below the evaporator. The fan has an air inlet at the lower end and an air outlet at the upper end. The evaporator has heat exchange copper tubes. An electric heating element is installed inside the water collection tank. A temperature sensor and a humidity sensor are installed inside the air outlet. An air conditioner outdoor unit is installed outside the air sterilizer and connected to the heat exchange copper tubes.

[0006] With the above structure, air is drawn into the sterilizer through the inlet, undergoes preliminary filtration through the first filter, then the air temperature is adjusted by the constant temperature and humidity module, the air is sterilized by the plasma generator, and finally, it undergoes secondary filtration through the second filter before being blown out through the outlet. Temperature and humidity sensors at the outlet measure the temperature and humidity of the blown air. When the air humidity is too high and needs to be reduced, the outdoor unit of the air conditioner introduces refrigerant into the heat exchange copper pipes. Moisture in the air condenses on the heat exchange copper pipes, forming condensate, thus reducing the air humidity. The condensate drips into the water collection tank. When the air temperature is too low and needs to be increased, the electric heating element heats the water in the water collection tank, accelerating water evaporation and increasing the moisture content in the air. When the air temperature is too low and needs to be increased, the outdoor unit of the air conditioner introduces a heating medium into the heat exchange copper pipe, which heats the air passing through. When the air temperature is too high and needs to be decreased, the outdoor unit of the air conditioner introduces a cooling medium into the heat exchange copper pipe, which cools the air passing through. This invention can simultaneously adjust the air temperature and humidity while filtering and disinfecting the air, in order to meet the requirements of both high cleanliness and constant temperature and humidity in indoor environments.

[0007] Preferably, in order to ensure that air passes through the evaporator normally, a wind guide plate is provided above the water tank. The wind guide plate is trumpet-shaped, with a lower opening at the lower end and an upper opening at the upper end. The diameter of the upper opening is smaller than the diameter of the lower opening.

[0008] Preferably, in order to facilitate the collection of condensate in the water collection tank, a water collection plate is provided below the evaporator. The water collection plate is funnel-shaped, with a water inlet at the upper end and a water outlet at the lower end. The diameter of the water inlet is larger than the diameter of the water outlet, and the diameter of the water outlet is less than or equal to the diameter of the opening on the air guide plate.

[0009] Preferably, to avoid too much or too little water in the water collection tank, the water collection tank is equipped with a water supply pipe and a water discharge pipe.

[0010] Preferably, in order to facilitate the detection of the liquid level in the water collection tank, the water collection tank is equipped with a low liquid level sensor and a high liquid level sensor, with the low liquid level sensor located below the high liquid level sensor.

[0011] Preferably, in order to facilitate the control of the opening and closing of the water supply pipe and the water outlet pipe, both the water supply pipe and the water outlet pipe are equipped with solenoid valves.

[0012] Preferably, in order to ensure the filtration effect of the first filter device and the second filter device, the first filter device is a pre-filter and the second filter device is a medium-efficiency filter.

[0013] Preferably, in order to ensure the filtration effect of the first filter device and the second filter device, the first filter device is a pre-filter and the second filter device is a high-efficiency filter. Attached Figure Description

The water collection tank is provided with an electric heating tube 13. The air outlet is provided with a temperature sensor 14 and a humidity sensor 15. An air conditioner outdoor unit 16 is provided outside the air sterilizer and is connected to the heat exchange copper tube. A wind deflector 17 is installed above the water tank. The wind deflector is trumpet-shaped, with a lower opening 18 at its lower end and an upper opening 19 at its upper end. The diameter of the upper opening is smaller than the diameter of the lower opening. A water collection plate 20 is installed below the evaporator. The water collection plate is trumpet-shaped, with a water inlet 21 at its upper end and a water outlet 22 at its lower end. The diameter of the water inlet is larger than the diameter of the water outlet, and the diameter of the water outlet is less than or equal to the diameter of the opening on the wind deflector. The water collection tank is equipped with a water supply pipe 23, a water discharge pipe 24, a low liquid level sensor 25, and a high liquid level sensor 26. The low liquid level sensor is located below the high liquid level sensor. Both the water supply pipe and the water discharge pipe are equipped with solenoid valves.

[0018] In some cases, the first filtration device is a pre-filter and the second filtration device is a medium-efficiency filter.

Temperature and humidity sensors at the outlet measure the temperature and humidity of the blown air. When the air humidity is too high and needs to be reduced, the outdoor unit of the air conditioner introduces refrigerant into the heat exchange copper pipes, causing moisture in the air to condense into condensate, thus reducing the humidity. The condensate drips into the water collection tank. When the air humidity is too low and needs to be increased, the electric heating element heats the water in the water collection tank, accelerating evaporation and increasing the moisture content in the air. When the air temperature is too low and needs to be increased, the air conditioner... The outdoor unit introduces a heating medium into the heat exchange copper pipes, which heats the air passing through them. When the air temperature is too high and needs to be lowered, the outdoor unit introduces a cooling medium into the heat exchange copper pipes, which cools the air passing through them. Low and high level sensors detect the water level in the water tank to prevent it from becoming too high or too low. When the water level is too low, the solenoid valve of the water supply pipe is opened to add water to the tank. When the water level is too high, the solenoid valve of the drain pipe is opened to release excess water. This invention can simultaneously adjust the air temperature and humidity during air filtration and disinfection to meet the requirements of a clean and constant temperature and humidity indoor environment.
