Description

Technical Field

[0001] The present invention relates to a non-fog humidifier. Background Art

[0002] With the continuous development of technology, humidifiers are deeply loved by consumers for humidifying dry air, compensating for moisture in the air, and improving the comfort of the living environment.

[0003] Most traditional humidifiers use an atomizing device to heat and atomize water and then output it into the air for humidification. Although this type of humidifier can humidify dry air and compensate for moisture in the air, the humidification technology of the humidifier generally uses electronic technologies such as ultrasonic waves to break water into particulate form to form atomized water vapor for humidifying the air. As a result, the humidifier has a complex structure, high manufacturing cost, poor humidification effect, and the particulate water inhaled into the human body has certain health hazards to the human body, and the reliability is low.

[0004] Therefore, enterprises have developed a non-fog humidifier with natural humidification, which filters and purifies the air through a wet curtain to ensure the safety and reliability of the use of the humidifier. At the same time, the physical humidification method of natural humidification reduces the production cost of the humidifier. Since traditional humidifiers are provided with a separate water tank inside the humidifier, when the water in the water tank needs to be replenished, the water tank must be removed from the humidifier and reinstalled into the humidifier after replenishment.

[0037] The present invention will be further described below in conjunction with the drawings and embodiments.

[0038] Refer to Figures 1-14, a fogless humidifier, comprising a body assembly 10, a water tank 20 and a wet curtain assembly 40. The body assembly 10 and the water tank 20 are arranged at an upper and lower interval. There is an annular air outlet area 30 between the body assembly 10 and the water tank 20. The wet curtain assembly 40 is arranged in the annular air outlet area 30. The body assembly 10 at least includes a casing 100 with openings at both upper and lower ends. The lower end of the casing 100 is internally communicated with the wet curtain assembly 40. A fan assembly 60 is arranged inside the wet curtain assembly 40. An inlet hood 110 is arranged at the upper part of the casing 100. An inlet cavity 111 is arranged inside the inlet hood 110. An annular air inlet area 120 is formed between the outer wall of the inlet hood 110 and the inner wall of the casing 100. The annular air inlet area 120 is downwardly communicated with the inside of the wet curtain assembly 40. A pipeline assembly 920 extending downward to the upper part of the water tank 20 is further arranged on the casing 100. A water discharge pipeline 921 and a water supply pipeline 922 are respectively arranged inside the pipeline assembly 920. The lower end of the water discharge pipeline 921 is internally communicated with the water tank 20. The upper end of the water discharge pipeline 921 is internally communicated with the inlet cavity 111. A water supply assembly 50 is further arranged inside the casing 100. One end of the water supply assembly 50 is connected to the upper end of the water supply pipeline 922, and the other end is connected to the wet curtain assembly 40. A water pump assembly 80 is arranged inside the water tank 20. The output end of the water pump assembly 80 is connected to the lower end of the water supply pipeline 922.

[0039] In the present invention, when water needs to be added to the water tank, an external water source is added to the inlet cavity, and then enters the inside of the water tank through the water discharge pipeline.

[0040] In the present invention, during operation, the fan assembly 60 is started, driving external air to enter the casing 100 from the annular air inlet area 120, and then the air passes downward through the driving of the fan assembly 60 through the wet curtain assembly 40 and is output to the outside from the annular air outlet area 30.

[0041] While the fan assembly 60 is started, the water supply assembly can extract the water inside the water tank 20 and then transport it to the wet curtain assembly to be fused with the wet curtain to moisten the wet curtain. At the same time, the operation of the fan assembly can drive external air through the wet curtain. During this process, the air passes through the wet curtain and is mixed with the moisture in the wet curtain to form moist air, which is blown out from the annular air outlet area 30 and mixed with the external air, thereby achieving the humidifying effect.

[0042] See Figure 3 and Figure 4, a first heating component 70 is provided in the casing 100 above the fan component 60.

[0044] In the existing mist-free humidifier, water is first heated, then the heated water is sprayed on the wet curtain, and then the air flows through the wet curtain and mixes with the water molecules of the wet curtain to achieve mist-free humidification. In the present invention, a first heating component is provided between the annular air inlet area and the fan component.

[0045] The first heating component can enable the external air drawn in by the fan component to be heated by the first PTC ceramic heater 720 to form hot air, and the heated hot air then passes through the wet curtain and blows to the outside. By the contact between the hot air and the wet curtain, part of the unatomized water molecules can be further heated and atomized by the hot air. To reduce the water content in the air and improve the humidification effect.

[0046] See Figure 10 and Figure 11 , an annular installation area 101 is further provided in the casing 100. The water supply component 50 is provided in the annular installation area 101.
